REPOSAL successfully developed string winding machine

heading_title

      REPOSAL  takes the string winding machine as the research object and adopts the modal analysis method. Firstly, the vibration principle and the movement principle of the winding mechanism of the small string winding machine are discussed in theory. Based on the principle analysis, the vibration analysis of the ADAMS model of the small copper wire winding mechanism to study the vibration damping characteristics between the roller shaft and the frame is carried out respectively, and the wire winding mechanism of the string winding machine is made using ANSYS software. Modal analysis was carried out for normal operation. Through analysis, the vibration characteristics of the winding mechanism of the string winding machine under normal working conditions are obtained respectively to optimize the vibration damping measures of the winding mechanism. At the same time, the mechanical characteristics of the thin wire and CNC under the normal working state of the CNC winding mechanism are analyzed. , Optimizing the feasibility of applying the CNC cable winding mechanism to the string winding machine cable winding mechanism.

            

       Based on the vibration analysis of the winding mechanism of the string winding machine and the mechanical analysis of the winding mechanism, the roller shaft and the frame factors that affect the vibration characteristics of the small string winding machine are taken as the research objects. The ADAMS software is used to analyze and improve the small string winding. The influence of the vibration generated by the winding mechanism of the winding machine on the thin copper wire and the working environment, and the factors of the thin copper wire and the CNC wire winding mechanism that affect the arrangement characteristics of the copper wire of the small string winding machine are analyzed using ANSYS software to improve the small The twisting and twisting phenomenon of the copper wire that may appear in the winding mechanism of the string winding machine has an effect on the copper wire coil finally obtained. Finally, the winding mechanism of the string winding machine and the winding mechanism are combined to use the actual operation, and the physical principle of the small string wire winding machine platform is used to actually flatten the various types of filaments to finally test the above principle. The final copper wire coil is obtained.

             

The conclusions drawn through the discussion in each chapter mainly include the following:

1. After analyzing the overall structure of the string winding machine, the string winding machine is divided into the string winding machine winding mechanism and the string winding machine with the CNC winding mechanism spindle as the boundary. Cable arrangement. The above mechanism decomposition is to facilitate the study of how to obtain high-quality thin copper wire and how to arrange the thin copper wire neatly on the bobbin.

2. The theoretical analysis of the application of vibration mechanics theory to the winding mechanism of the string winding machine through the actual situation that the periodic movement of the roller shaft of the string winding machine during normal operation produces a periodic excitation force for the entire mechanism Increasing the mass m of the frame and reducing the rigidity k of the screw-compressed sliding table can reduce the vibration transmission rate of the system.

3. The ADAMS simulation model is established by applying the ADAMS software based on the actual situation to verify the theoretical analysis of the applied vibration mechanics. The results show that increasing the equivalent mass of the frame m or reducing the rigidity k of the screw-pressed sliding table or at the same time Increasing the equivalent mass m of the frame and reducing the stiffness k of the screw-pressed sliding table can effectively reduce the peak value of the acceleration curve of the vibration response function caused by the excitation force generated by the motion of the roller shaft to reduce the vibration transmission efficiency. The implementation of the above measures can increase the life of the machine, reduce the burden on the worker's body at the same time, and also greatly improve the quality of the flattened filament.

4 The string winding mechanism of the string winding machine is based on the actual characteristics of various types of wire winding devices and the specific characteristics of the thin copper wires that need to be wired. The numerical control cable arrangement with the characteristics of convenient manufacturing and small occupied area is used as the cable arrangement device

5. Using ANSYS software to simulate the movement and force of the thin copper wire passing between the cable spool and the spool according to the actual conditions. The simulation results show that the fine copper wire is arranged on the bobbin after passing through the CNC cable arrangement mechanism. The force applied during the process is mainly the force along the length of the copper wire that can arrange the copper wire neatly on the take-up spool. The second most important force is to cause the copper wire to flip, and the external force acting on the edge of the copper wire is twisted. At the same time, the displacement of the thin copper wire under the action of tension, gravity and other forces in this process is mainly to ensure that the thin copper wire is neatly arranged. Flip, twist, and twist the displacement forward, backward, left, and right. Through software simulation and actual inspection, a satisfactory copper wire coil was finally obtained. The design purpose of the string winding machine is realized.

    REPOSAL research analyzes and studies how to improve the quality of the flattened filaments under normal working conditions, and discusses how to arrange fine copper filaments on the spools. practice.

Although due to the existence of practical constraints, the simulation data used in ADAMS and ANSYS software can only select a part from a reasonable interval and cannot apply the data obtained by actual detection of actual sensors with high accuracy, so there will be certain simulation analysis error. However, in the actual development process, we have successfully developed the string winding machine through the accumulation of advanced digital control technology and rich winding technology.

REPOSAL® successfully developed linear motor winding machine

          The linear motor winding machine developed by Suzhou REPOSAL® Electronic Machinery Equipment Co., Ltd. successfully completed the test, achieved success, and was successfully put into production.

          At present, in traditional linear motor winding machines, the stator coils are individually wound and then assembled on the linear motor core in sequence, and then welded between the stator coils. The process is many, the efficiency is low, and there are many process nodes such as manual intervention assembly and welding. At the same time, the quality is unstable, which affects the cost of the traditional linear motor for a long time. The successful research and development of the linear motor winding machine of this specification will further reduce the cost of the linear motor and improve its quality.

          Based on the process of this linear motor winding machine, the company has reached a further research and development agreement with long-term cooperative customers to replace the traditional circular stator coil inner winding process. There are two reasons for its cost to apply the company's linear motor After the winding machine, there is a very large drop space. One is because the existing inner winding stator coil has a toroidal core, so the utilization rate of the material is low. The current plan is to design it as an unfolded type. The utilization rate will be at least doubled. The second is the inner winding of the stator coil. Due to technological limitations, its winding method can only be wound by a single wire. The REPOSAL'slinear motor winding machine winds three windings at the same time, and its processing efficiency is tripled. The combination of the two aspects will greatly reduce the cost of the inner winding stator coil.

          At the same time, Suzhou REPOSAL® Electronic Machinery Equipment Co., Ltd. will further optimize the design and production process, and strive to continue to reduce the cost of the whole machine under the existing cost advantage, so that the production company can save materials and improve efficiency, while also greatly reducing The purchase and use cost of the winding machine-make REPOSAL's partners more competitive.

Common mode inductor winding machine 2

Common mode inductor winding machine 2

The function of common mode inductor is to suppress common mode interference, and it is a relatively important filter inductor.

       

       It is different from a differential mode inductor. Although the two types of inductors are filter inductors, the different functions determine the appearance and winding method will be different. For the common mode inductor, it is wound on the same core, and the two The coil diameter of each winding is the same as the number of turns, but the winding direction is opposite. A set of coils has two pins, so the common mode inductor has 4 pins; while the differential mode inductor is wound on a core and only has A coil, so it has only 2 pins, so the common mode inductance and the differential mode inductance can be distinguished from the number of pins.


     Also because the common mode inductor is two windings with opposite winding directions, the ideal winding effect is that the arrangement of the positive and negative directions is neat.

Solenoid valve winding machine|Solenoid valve coil precision winding machine|Precision winding machine:

        For precision electromagnetic coils, there are usually many turns, which require neat arrangement, and the process design is also divided into two types with and without skeleton.

For frameless coils, steel molds are required to form.Relatively speaking, the precision of steel winding molds is better controlled.

        Under the existing solenoid valve winding machine processing technology, it is not difficult to achieve a size of 0.01mm on both sides of the steel winding mold, and the parallelism on both sides is 0.01

mm is also not difficult. However, if there is no wire frame mold steel wire winding mold, there will be two new problems, one is forming, the winding is completed

After the final removal, there is no skeleton.To prevent the coil from being scattered, it is necessary to use an alcohol fuse or a hot fuse. These two materials

Compared with the ordinary wire, the cost is not small. The second problem is demolding, a thicker one, and more windings

It's quite laborious to remove the coil from a steel mold, it's not like a coil with a small coin, and

What's more, this winding process itself has viscous materials that are melted or hot melted.

        So people also use the second solenoid valve winding machine process, a precision electromagnetic coil with a skeleton.Similarly, this is not a very good process route.

The skeleton is formed by an injection mold, and there are inevitably some problems with injection products, such as deformation, shrinkage, dimensional consistency, etc.

        However, the advantages of this solenoid valve winding machine are also obvious, that is, it is easy to demold and form. It is only because of the poor consistency of the size of the skeleton.

Higher requirements are put forward, the key point is that wire, skeleton structure, skeleton mold, winding tooling, winding machine, every link

Will affect the quality of the winding, in this case, according to our own advantages, we provide a complete service according to customer needs

Including skeleton design, mold structure design, tooling design, and winding machine. In the past successful cooperation, this way of service Gret advantages.
