[0002] During the motor production process, our company needs to place the stator wiring harness in the surrounding Fig.13 In the module, there is a guide plate in the module, which can be driven to expand outward by the extrusion block, and then the wiring harness is squeezed outward to be inserted into the stator slot. There are multiple guide posts for guiding between adjacent wiring harnesses. The wiring harness moves in the direction of the stator wiring harness slot. There may be friction between the stator wiring harness slot and the wiring harness, which can easily cause the wiring harness to scratch the stator wiring harness slot, resulting in defective products. Therefore, a mechanism is needed to guide the stator wiring harness to be inserted and to prevent the wiring harness from damaging the stator wiring harness slot.

[0003] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a motor stator wave winding embedding device to make it more valuable for industrial use. Summary of the invention

[0004] In order to solve the above technical problems, the object of the present invention is to provide a motor stator wave winding embedding device.

[0005] A motor stator wave winding and embedding device of the present invention comprises a frame, a working platform is provided in the middle of the frame, two sets of parallel guide rails are fixed above the working platform, a lower mounting plate is installed on the guide rail through a slider, a lower guide disk is fixed on the lower mounting plate, the outer side of the guide rail is composed of a plurality of guide rollers fixed on the working platform, an upper mounting plate which can move up and down is sleeved on the guide roller, an upper guide disk is fixed on the upper mounting plate, a support plate is fixed on the upper end of the guide roller, an upper pressure assembly is installed on the support plate, and a lower pressure assembly is installed below the working platform.

[0006] This motor stator wave winding wire embedding device has a lower mounting plate that can move forward and backward, and is used to drive the lower guide plate to move to the module installation station. After the module is placed, it is moved to the wire harness embedding station. The upper guide plate and the lower guide plate are used together to guide the wire harness on the module. Under the drive of the upper pressure component and the lower pressure component, the guide plate in the module expands outward to press the wire harness tightly into the wire harness groove of the stator.

[0007] Furthermore, the lower guide plate and the upper guide plate have the same structure and are respectively fixed on the lower mounting plate and the upper mounting plate in a mirror-image manner.

DETAILED DESCRIPTION

[0025] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] See also Figure 1-Figure 3This motor stator wave winding and embedding device has a flat working platform 2 at the upper end of the frame 1. Two parallel guide rails 3 are installed on the working platform 2 through a bracket. The lower mounting plate 4 is movably installed on the guide rails 3 by means of a slider. There are two sets of vertical guide rollers 6 on both sides of the working platform 2. The upper mounting plate 4 is sleeved on the guide rollers 6 so that the upper mounting plate 4 can move up and down. The upper and lower guide plates 5 of the lower mounting plate 4 can be moved to the end of the guide rails 3 to facilitate the placement of the module. After the module is placed, the lower mounting plate 4 is moved to the bottom of the upper mounting plate 7, and the upper pressing assembly 10 and the lower pressing assembly 11 work to push the guide plate 32 in the module outward, driving the wiring harness in the module to be inserted into the wiring harness groove of the stator.

[0027] The lower guide plate 5 installed on the lower mounting plate 4 and the upper guide plate 8 installed on the upper mounting plate 7 have the same structure and are fixedly installed in a mirrored manner, so that the lower guide plate 5 and the upper guide plate 8 can guide the wiring harness on the module.

[0028] See also Figure 5-Figure 9 The lower mounting plate 4 and the upper mounting plate 7 are fixedly connected to the lower guide plate 5 and the upper guide plate 8 through the adapter frame 12. There is a rotatable mechanism in the lower guide plate 5 and the upper guide plate 8. The rack on the outer ring of this rotating structure is engaged with the gear installed on the guide plate motor 13. Therefore, when the guide plate motor 13 is working, it can drive the rotating mechanism in the lower guide plate 5 and the upper guide plate 8 to rotate.

[0029] The chassis 14 on the lower guide plate 5 and the upper guide plate 8 is fixedly connected to the adapter frame 12, and the upper plate 15 is fixedly connected to the chassis 14. The lower cover plate 16 and the upper cover plate 17 between the upper plate 15 and the chassis 14 can rotate between the upper plate 15 and the chassis 14. Guide rods 18 arranged at intervals are also fixed between the upper plate 15 and the chassis 14. The upper guide rods 19 and the lower guide rods 20 are sequentially displaced in the gaps between the guide rods 18. The tail end of the upper guide rod 19 is equipped with an upward roller through a bearing, and the tail end of the lower guide rod 29 is equipped with a downward roller through a bearing. The two rollers are respectively stuck in the upper cover plate 17 and the lower cover In the slide groove 21 corresponding to the inner side of the plate 16, the structure of the upper cover plate 17 is consistent with that of the lower cover plate 16, so both have a slide groove 21. The upper cover plate 17 and the lower cover plate 16 are spliced ​​together to form a rotating mechanism in the lower guide plate 5 and the upper guide plate 8. The upper cover plate 17 and the lower cover plate 16 can be rotated under the drive of the guide plate motor 13. When the upper cover plate 17 and the lower cover plate 16 rotate, the relative position of the slide groove 21 changes, and the upper guide rod 19 and the lower guide rod 20 can be driven to extend inward by the roller stuck in the slide groove 21. After the upper guide rod 19 and the lower guide rod 20 extend inward, they are stuck between the upper wiring harness of the module to provide guidance for the movement of the wiring harness.

[0030] See also Figure 1A slide cylinder 22 is installed on the working platform 2 to drive the lower mounting plate 4 to move. The slide cylinder 22 is installed on the inner side of one of the guide rails 3. The slider of the slide cylinder 22 is fixedly connected to the lower mounting plate 4 to facilitate the movement of the lower mounting plate 4.

[0031] See also Figure 2 There are lifting motors 23 on both sides of the support plate 9 for driving the screw 24 to rotate. The lower end of the screw 24 is movably mounted on the top of the screw bracket 26. When the lifting motor 23 drives the screw 24 to rotate, the screw sleeve 25 of the upper mounting plate 7 set on the screw 24 can be driven to move up and down, thereby completing the purpose of driving the upper mounting plate 7 to move up and down.

[0032] See also Figure 3 , Fig.10 , Fig.11 as well as Fig.12 The upper electric cylinder 27 of the upper pressure assembly 10 is fixed on the support plate 9, and the lower electric cylinder 29 of the lower pressure assembly 11 is fixed on the frame 1. The upper pressure block 28 and the lower pressure block 31 are respectively fixed on the upper electric cylinder 27 and the lower electric cylinder 29. The lower pressure block 31 is sleeved in the guide sleeve 30. The upper electric cylinder 27 and the lower electric cylinder 29 respectively drive the upper pressure block 28 and the lower pressure block 31 to move, so that the upper pressure block 28 and the lower pressure block 31 are inserted into the module to compress the guide plate 32 to expand outward to complete the installation of the wiring harness.

[0033] The working principle of the present invention is as follows: When this motor stator wave winding wire embedding device is working, first the lower mounting plate 4 is moved forward driven by the slide cylinder 22, and the module is placed in the lower guide plate 5 on the lower mounting plate 4, and then the slide cylinder 22 drives the lower mounting plate 4 to reset, and then the upper and lower guide plate motors 13 are started, respectively driving the corresponding lower guide plate 5 and the lower cover plate 16 and the upper cover plate 17 in the upper guide plate 8 to rotate, and the upper guide rod 19 and the lower guide rod 20 are inserted into the gap between the upper wire harnesses of the module, and the spacing between the upper guide rod 19 and the lower guide rod 20 is slightly larger than the spacing between the upper wire harness grooves of the stator, and then the upper electric cylinder 27 and the lower electric cylinder 29 drive the upper pressure block 28 and the lower pressure block 29 respectively. 31 is pushed into the module, and the guide plates 32 at the upper and lower ends of the module are pushed outward. The guide plates 32 contact the wiring harness, thereby moving the wiring harness outward and installing the wiring harness in the wiring harness slot of the stator to complete the installation of the wiring harness. Subsequently, the upper electric cylinder 27 and the lower electric cylinder 29 are reset, and the upper pressure block 28 and the lower pressure block 31 are separated from the module. Subsequently, the guide disk motor 13 rotates, respectively driving the lower guide disk 5 and the upper guide rod 19 and the lower guide rod 20 in the upper guide disk 8 to reset, so that the upper guide rod 19 and the lower guide rod 20 are separated from the module. Finally, the slide cylinder 22 drives the lower mounting plate 4 to move to the end of the guide rail 3. At this time, the module with completed wiring can be taken out and enter the subsequent processing station.
