Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0022] like Figures 1 to 4 As shown, an automatic glue coating device for motor coils includes a glue coating platform 1, a conveying platform 5, a conveyor belt 7 and an operating fixture 6. The glue coating platform 1 is used to place a single coil 100 to be glued, the conveying platform 5 is used to transport the coil 100 to be glued, the conveyor belt 7 is used to send away the glued coil 100, and the operating fixture 6 is used to transfer the glued coil 100 on the conveying platform 5 to the glue coating platform 1, and then transfer the glued coil 100 from the glue coating platform 1 to the conveyor belt 7.

[0023] Specifically, the conveying platform 5 includes a driving source, a roller 52, a chain 53 and a conveying belt 51. The chain 53 is meshed with the roller 52 and the output end of the driving source at the same time. The conveying belt 51 is covered on the outside of the roller 52. The driving source can be a motor. The driving source is used as a power source to drive the chain 53 to rotate, thereby driving the roller 52 to rotate, and then using the friction force to drive the conveying belt 51 covered on the outside of the roller 52 to move, thereby realizing the transfer of the coil 100 to be wrapped with rubber.

[0024] The operating fixture 6 includes a driving base 61 and a rotating arm 62, one end of the rotating arm 62 is fixed on the driving base 61, and the driving base 61 can drive the rotating arm 62 to rotate; the free end of the rotating arm 62 can be rotated to the top of the conveying platform 5, the rubber-coated platform 1 and the conveying crawler 7 to realize the transportation of the coil 100. Among them, the free end of the rotating arm 62 is provided with a fixing component, and the fixing component includes a plurality of patches 621 surrounded in a circular ring. When the rotating arm 62 is used to move the coil 100, the fixing component is plugged into the inner ring of the coil 100, and the driving device in the rotating arm 62 drives the plurality of patches 621 to move outward until they are tightly against the inner wall of the coil 100, thereby completing the fixation of the coil 100, and then the conveyance of the coil 100 is realized by rotating the rotating arm 62.

[0025] The rubber-wrapping platform 1 is provided with a tape clamping platform 2, a tape pusher 3 and a shearing member 4, wherein the tape clamping platform 2 comprises a base 21, a first sub-clamping seat 23, a second sub-clamping seat 24 and a main clamping seat 22 which are arranged in sequence, and the tape reel 300 is fixed on the base 21. After the tape 200 passes through the first sub-clamping seat 23 and the second sub-clamping seat 24, the free end is clamped and fixed by the main clamping seat 22. The rubber-wrapping platform 1 is arranged on one side of the tape 200, the tape pusher 3 and the shearing member 4 are arranged on the side of the tape 200 away from the rubber-wrapping platform 1, and the tape pusher 3 and the shearing member 4 are arranged between the first sub-clamping seat 23 and the second sub-clamping seat 24. The tape pusher 3 includes a mounting seat 31 and a roller 32. The mounting seat 31 drives the roller 32 to move toward the coil 100 to be glued, so that the tape 200 is adhered to the side wall of the coil 100; the shearing piece 4 is arranged next to the tape pusher 3 and moves synchronously with the tape pusher 3. After the tape pusher 3 adheres the tape 200 to the coil 100, the shearing piece 4 cuts off the tape 200.

[0026] The main clamping seat 22 includes a base 221 and a clamping member 222. The clamping member 222 can move toward the first sub-clamping seat 23 under the drive of the hydraulic push rod. After the shearing member 4 cuts the tape 200, the rubber-wrapping platform 1 drives the coil 100 to rotate, and the clamping member 222 moves toward the first sub-clamping seat 23. Under the abutment of the roller 52, the tape 200 can be driven to wrap around the side wall of the adhesive coil 100. It should be noted that the tape pusher 3 and the shearing member 4 move horizontally between the base 21 and the main clamping seat 22 along the tensioning direction of the tape 200, and the length of the tape 200 between the shearing member 4 and the main clamping seat 22 is the same as the circumference of the outer wall of the coil 100 to be rubber-wrapped.

[0027] The second sub-clamping seat 24 includes a first section 241 and a second section 242. The first section 241 and the second section 242 can move relative to each other to achieve opening and pressing. When the coil 100 is being coated with rubber, the first section 241 and the second section 242 are pressed together to clamp the tape 200. When the coating is completed, the first section 241 and the second section 242 are opened. At this time, the clamping member 222 can move toward the first sub-clamping seat 23, and after passing through the second sub-clamping seat 24, the free end of the cut tape 200 is re-clamped. The clamping member 222 clamps the free end of the cut tape 200 and then resets it to its original position, so that the next coil 100 can be coated with rubber.

[0028] Furthermore, the base 21 includes a fixed column 211 and a guide column 212 that are arranged at intervals. The fixed column 211 is inserted into the tape reel 300 to fix the tape reel 300. An annular limiting groove 2121 is opened on the side of the guide column 212, and the height of the limiting groove 2121 is the same as the width of the tape 200. When the tape 200 is tensioned, the tape 200 passes through the limiting groove 2121 and is limited by the guide column 212, thereby reducing the situation where the tape 200 moves up and down during the gluing process.

[0029] The present application also provides a method for automatically coating a motor coil, using the above-mentioned automatic coating device for a motor coil, comprising the following steps: S1: using the rotating arm 62 to transport the coil 100 to be glued from the conveyor belt 51 to the glue-coating platform 1; S2: After the tape pusher 3 pushes the tensioned tape 200 to adhere to the side wall of the coil 100 to be glued, the shearing member 4 moves and cuts off the tape 200; S3: The glue coating platform 1 drives the coil 100 to be glued to rotate, and at the same time the main clamping seat 22 moves towards the direction of the second sub-clamping seat 23, and the glue coating is completed after one circle of rotation; S4: The rotating arm 62 moves the glued coil 100 to the conveyor belt 7; S5: The second sub-clamping seat 23 is separated, and the main clamping seat 22 moves to the first sub-clamping seat 24 to clamp the free end of the adhesive tape 200, tensioning the adhesive tape 200 and moving it back to its original position; S6: Repeat steps S1-S5 to carry out the gluing work of the next coil 100.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
