[0002] In order to ensure that linear motor module can still be used as motion control under various installation environments, linear motor module still needs to be normally installed under the condition of limited space.
[0003] The linear motor mover not only represents the motion control of the linear motor module, but also has a close relationship with the structure size of the linear motor module. The upper end of the linear motor mover cooperates with the linear motor sliding seat, and the sliding seat connected with the linear motor mover is connected with the sliding block and the guide rail to provide the track and support for the movement of the linear motor mover. As the structure for connecting the upper and lower, the size of the linear motor mover determines the size of the entire linear motor module, so in the traditional linear motor mover specification, the standard size determines that it is difficult for the linear motor module to be closer to a smaller width. SUMMARY
[0004] The inventor of the present application finds that the specification of the standard linear motor mover is limited by the connection of the PCB board, and it is difficult to further reduce it on the basis of the original. Based on this, the technical problem to be solved by the utility model is to provide a linear motor module which further reduces the specification of the linear motor mover by removing the connection of the PCB board, thereby solving the problem that the width of the linear motor module is difficult to be designed to a smaller distance.
[0005] To solve the above technical problems, the utility model adopts the technical scheme of a linear motor module, comprising: a mover substrate, a stator substrate, a plurality of magnetic strips arranged at intervals on the surface of the stator substrate facing the mover substrate, a plurality of coil windings, and a mover core mounted on the surface of the mover substrate facing the stator substrate, a plurality of mover tooth portions corresponding to the coil windings are formed on the mover core opposite to the side of the mover substrate, and each of the mover tooth portions arranged at intervals with adjacent mover tooth portions is correspondingly sleeved with one of the coil windings, each of the coil windings is provided with two outwardly extending lead wires, the lead wires of the plurality of coil windings and the lead wires of the coil windings are connected by a wire, and the other end of the wire cable is used for electrical connection with an external cable.
[0006] The further improved scheme in the above technical solution is as follows:
[0007] 1. In the above scheme, a limiting groove for embedding the sleeve is formed on the side surface of the moving substrate.
[0008] 2. In the above scheme, the limiting groove is formed in the center of the moving part substrate side surface.
[0009] 3. In the above scheme, the coil winding is obtained by processing copper wire, and the lead wire is copper wire.
[0010] 4. In the above scheme, the moving substrate is an aluminum substrate and the stator substrate is an iron substrate.
[0011] 5. In the above scheme, the moving core is composed of several stacked silicon steel sheets.
[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:
[0013] This utility model linear motor module includes a mover base plate, a stator base plate, several magnetic strips spaced apart on the surface of the stator base plate facing the mover base plate, several coil windings, and a mover core mounted on the surface of the mover base plate facing the stator base plate. Each coil winding has two outwardly extending leads. The leads of the coil windings are connected to each other and to one end of an output cable via wires. The other end of the output cable is used for electrical connection with an external cable. A conduit is sleeved on the outer side of the connection between leads and the connection between leads and the output cable. Direct connection of wires replaces the soldering of circuits on the PCB board, realizing electrical connection between coils and between coils and output cables. The conduit improves the convenience of wiring and the stability of the connection structure at the connection point. This simplifies the manufacturing process and saves the space required by using a PCB board, thereby reducing the size of the product. Attached Figure Description
