Description

Technical Field

[0001] The present invention relates to the technical field of motor stator assembly, and particularly to a wire embedding and paper feeding mechanism for motor stator assembly. Background Art

[0002] Insulating paper and slot cover paper are often required in the stator. Since the lengths of the insulating paper and the slot cover paper are different, it is often necessary to install the insulating paper and the slot cover paper into the stator slots in two steps.

[0003] In terms of traditional means, it is necessary to first manually insert the insulating paper into the stator slots, and then repeat the above actions to insert the slot cover paper into the stator slots. On the one hand, the work efficiency of manually inserting the slot cover paper and the insulating paper is low, and the error rate is relatively high, ultimately resulting in a relatively high defective rate of the stator. On the other hand, dividing the installation of the slot cover paper and the insulating paper into two steps takes a relatively long time, directly slowing down the production time and reducing the production efficiency. Moreover, even if mechanical means are used to install the insulating paper and the slot cover paper into the stator slots, traditional means still require cutting the insulating paper and the slot cover paper and first installing them into the mold, and then moving the mold to the machine that can install the insulating paper and the slot cover paper, which is time-consuming and laborious, with low work efficiency and low automation. At the same time, if corresponding effects are to be achieved, usually multiple machines need to cooperate, wasting resources.

[0004] In the utility model patent of the applicant's prior application, the application number is: 202021233713.X, and the name is: A hybrid wire embedding and paper feeding mechanism for motor stator. In this utility model, paper cutting, hybrid paper feeding and wire embedding are integrated into the same frame. The paper feeding part with a new design has high conversion efficiency and does not require manual operation. At the same time, in this application, a four-power drive is used for the wire embedding part, and the components of the wire embedding part do not interfere with each other, and insulating paper and slot cover paper with different lengths can be embedded into the stator at one time, with high work efficiency. However, in this application, the angle of the mold head is not convenient to adjust, and during the operation of the paper feeding mechanism, the length information of the paper cannot be obtained, nor can it be obtained whether the paper is being fed, that is, there may be a situation where the paper feeding mechanism is running but no paper is output. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose a wire embedding and paper feeding mechanism for motor stator assembly.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A wire embedding and paper feeding mechanism for motor stator assembly, comprising a bottom plate, an operation plate, a conversion disk, a die head and a paper feeding mechanism. The bottom plate is fixedly arranged below the operation plate. The conversion disk is rotatably installed at the upper end of the operation plate.

Two corresponding die heads are fixedly installed at the upper end of the conversion disk. The die head is provided with evenly distributed wire embedding channels. A paper feeding mechanism and a paper embedding mechanism adapted to the die head are fixedly installed at the lower end of the operation plate.

[0008] It further includes an angle adjusting mechanism for adjusting the angle of the die head.

[0009] Preferably, the die head includes a tooth protection sleeve, a die chassis, a card slot, a wire package chuck, a guide bar tray, a clutch joint, a push rod, a push head, a fixed guide bar, a storage bar and a wire embedding channel. The lower end of the die chassis is fixedly connected to the tooth protection sleeve. The lower end of the clutch joint passes through the die chassis.

Two corresponding guide bar trays are fixedly arranged inside the tooth protection sleeve. The upper end of the push rod passes through the upper guide bar tray and is fixedly connected to the lower end of the push head. A first groove for inserting the fixed guide bar is arranged on the inner wall of the tooth protection sleeve. A second groove for inserting the storage bar is arranged on the side wall of the guide bar tray. The area between adjacent storage bars forms a wire embedding channel.

A compression spring is fixedly installed on the third mounting plate. The end of the compression spring is rotatably installed with a paper feeding induction wheel. The end of the paper feeding induction wheel passes through the slot cover paper forming channel cover plate. An encoder is fixedly installed on the end face of the paper feeding induction wheel. The paper feeding forming wheel and the paper feeding pressure wheel are rotatably arranged on both sides of the slot cover paper forming channel and the slot cover paper forming channel cover plate. The paper feeding forming wheel and the paper feeding pressure wheel are adapted to each other. A third cylinder is further installed on the third mounting plate. The output end of the third cylinder is installed with a cutter through a tool holder. The cutter is located at the paper outlet of the paper feeding mechanism.

[0011] Preferably, a paper feeding servo motor for driving the paper feeding pressure wheel to rotate is installed on the third mounting plate. A fourth gear is installed on the rotating shaft of the paper feeding forming wheel, and a fifth gear is installed on the rotating shaft of the paper feeding pressure wheel. The fourth gear meshes with the fifth gear. The paper feeding servo motor drives the paper feeding pressure wheel to rotate. The paper strip moves forward through the gap between the groove cover paper forming channel and the cover plate of the groove cover paper forming channel. Through the cooperation of the paper feeding induction wheel, the compression spring and the encoder, the length of the paper strip is tracked and detected. When the specified length is reached, the paper strip is cut off by the cutter driven by the third cylinder. The whole device is provided with four groups of paper feeding mechanisms, and the four groups of paper feeding mechanisms work together to effectively improve the paper feeding efficiency.

[0012] Preferably, a sliding plate is further arranged on the third mounting plate. The paper feeding servo motor is fixedly installed on the sliding plate. A second cylinder for driving the sliding plate to move is fixedly installed on the third mounting plate. The second cylinder can drive the sliding plate to move, so that the paper feeding pressure wheel is separated from the paper forming wheel, facilitating the insertion of the paper strip.

[0013] Preferably, the angle adjustment mechanism includes a first mounting plate, an angle adjustment servo motor, a first cylinder, a second mounting plate, a rotating block, an angle adjustment mechanism belt, a positioning block, a first gear, a second gear and a third gear. The first mounting plate is fixedly connected to the second mounting plate through a support rod. The angle adjustment servo motor and the first cylinder are fixedly installed on the first mounting plate. The output shaft of the angle adjustment servo motor drives the rotating block to rotate through the angle adjustment mechanism belt. The rotating block is a hollow structure, and the end of the rotating block is rotatably connected to the second mounting plate. A positioning rod is inserted into the interior of the rotating block. The rotating block can drive the positioning rod to rotate, and the positioning rod can move along the axis of the rotating block. The lower end of the positioning rod is rotatably connected to the output end of the first cylinder. The upper end of the positioning rod is eccentrically provided with a positioning block. The first gear is eccentrically provided with a jack adapted to the positioning block. The first gear meshes with the second gear. The second gear meshes with the third gear. The third gear is used to drive the die head to rotate.

[0014] Preferably, the first gear and the second gear are rotatably installed on a conversion disk. The third gear is fixedly installed between a limit ring and a fixed ring. A connecting ring is sleeved outside the limit ring, and the limit ring is rotatably connected to the connecting ring. The upper end of the limit ring is fixedly connected to the lower end of the die chassis. The connecting ring is fixedly connected to the conversion disk. By the first cylinder, the positioning block is combined with or separated from the first gear. After the positioning block is combined with the first gear, the angle adjustment servo motor can drive the rotating block to rotate. The rotating block drives the positioning rod to rotate. Finally, the first gear is driven to rotate by the positioning block. The first gear, the second gear and the third gear cooperate with each other to drive the die head to rotate and adjust the angle of the die head to ensure the smooth progress of the paper inserting operation.

[0015] Preferably, it further includes a positioning pin. There is a through hole provided on the conversion disk, and the end of the positioning pin is adapted to the jack on the first gear. When the device is in a stopped state, insert the positioning pin into the jack to prevent the mold head from rotating.

[0016] Preferably, the specifications of the wire embedding channels are different.

[0017] The beneficial effects of the present invention are:

[0018] 1. An angle adjustment mechanism is provided in the device. Through the angle adjustment mechanism, the angle of the mold can be conveniently adjusted. That is, during the paper feeding process, after the insulating paper (slot cover paper) is sent to the wire embedding channel by the paper feeding mechanism, the angle adjustment servo motor in the angle adjustment mechanism rotates, driving the rotating block to rotate, and then being transmitted through the first gear, second gear, and third gear, thereby driving the mold head to rotate, automatically adjusting the angle of the mold head, aligning the next wire embedding channel to be paper-loaded with the outlet of the paper feeding mechanism, and effectively improving the processing efficiency.

[0019] 2. In the paper feeding mechanism of the device, a paper feeding induction wheel, a compression spring, and an encoder are provided. During the paper feeding process, under the action of the compression spring, the paper feeding induction wheel is in contact with the paper strip. The movement of the paper strip drives the paper feeding induction wheel to rotate, and the paper feeding induction wheel drives the encoder to rotate, obtaining the length information of the paper strip and whether the paper feeding mechanism is working properly, improving the working efficiency of the device.

[0020] 3. In the mold head of the device, wire embedding channels with different specifications are provided. Cooperating with the paper embedding mechanism, paper can be embedded for paper strips of different lengths and widths, further improving the paper embedding efficiency. At the same time, when the wire embedding channel becomes narrower, the floor area of the slot cover paper can be effectively reduced, the slot cover paper is not likely to protrude from the inner wall of the motor electronics, and it is also convenient for the installation of the stator coil.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0041] Refer to Figures 1-18 , a wire embedding and paper feeding mechanism for motor stator assembly, including a bottom plate 1, an operation panel 2, a conversion disk 3, a die head 5 and a paper feeding mechanism 8.

The upper end of the clutch joint 506 is fixedly connected to the lower end of the push rod 507 after passing through the guide bar tray 505. Two corresponding guide bar trays 505 are fixedly arranged inside the tooth guard sleeve 501. The upper end of the push rod 507 passes through the upper guide bar tray 505 and is fixedly connected to the lower end of the push head 508. A first groove for inserting the fixed guide bar 509 is provided on the inner wall of the tooth guard sleeve 501. A second groove for inserting the storage bar 510 is provided on the side wall of the guide bar tray 505. The area between adjacent storage bars 510 forms the inlay channel 511. A wire coil chuck 504 is provided on the outer wall of the tooth guard sleeve 501.

[0044] The specifications of the inlay channels 511 are different. For example, Figure 11 as shown, by adjusting the size of the storage bars 510, the inlay channels 511 can have different lengths or widths, enabling the inlaying of paper strips of different widths.

[0045] The paper feeding mechanism 8 includes a third mounting plate 801, a groove cover paper forming channel 802, a paper feeding induction wheel 803, a compression spring 804, an encoder 805, a paper feeding forming wheel 806, a paper feeding pressure wheel 807, a third cylinder 813, a groove cover paper forming channel cover plate 814, and a cutter 815. The third mounting plate 801 is vertically arranged, and the end of the third mounting plate 801 is fixedly connected to the lower end of the conversion disk 3. A vertically arranged groove cover paper forming channel 802 and a groove cover paper forming channel cover plate 814 adapted to the groove cover paper forming channel 802 are fixedly installed on the third mounting plate 801. A compression spring 804 is fixedly installed on the third mounting plate 801. The end of the compression spring 804 is rotatably installed with a paper feeding induction wheel 803. The end of the paper feeding induction wheel 803 passes through the groove cover paper forming channel cover plate 814. An encoder 805 is fixedly installed on the end face of the paper feeding induction wheel 803. The paper feeding forming wheel 806 and the paper feeding pressure wheel 807 are rotatably arranged on both sides of the groove cover paper forming channel and the groove cover paper forming channel cover plate 802. The paper feeding forming wheel 806 and the paper feeding pressure wheel 807 are adapted to each other. A third cylinder 813 is also installed on the third mounting plate 801. The output end of the third cylinder 813 is installed with a cutter 815 through a tool rest. The cutter 815 is located at the paper outlet of the paper feeding mechanism 8.

[0046] The third mounting plate 801 is equipped with a paper feeding servo motor 808 for driving the rotation of the paper feeding pressure wheel 807. A fourth gear 811 is mounted on the rotating shaft of the paper feeding forming wheel 806, and a fifth gear 812 is mounted on the rotating shaft of the paper feeding pressure wheel 807. The fourth gear 811 meshes with the fifth gear 812.

[0048] The working process of the paper feeding mechanism 8 is as follows: The paper feeding servo motor 808 drives the paper feeding pressure wheel 807 to rotate. Since the fourth gear 811 meshes with the fifth gear 812, the fifth gear 812 drives the fourth gear 811 to rotate, realizing the rotation of the paper feeding forming wheel 806. The paper strip passes through the paper feeding pressure wheel 807 and the paper feeding forming wheel 806 for forming. The paper strip moves forward through the gap between the slot cover paper forming channel 802 and the slot cover paper forming channel cover plate 814. Through the cooperation of the paper feeding induction wheel 803, the compression spring 804 and the encoder 805, the length of the paper strip is tracked and detected. When the specified length is reached, the cutter 815 is driven by the third air cylinder 813 to cut the paper strip. The whole device is provided with four groups of paper feeding mechanisms 8, and the four groups of paper feeding mechanisms 8 work together to effectively improve the paper feeding efficiency.

[0049] The second air cylinder 809 can drive the slide plate 810 to move, so that the paper feeding pressure wheel 807 is separated from the paper forming wheel 806, facilitating the insertion of the paper strip.

[0050] The angle adjustment mechanism 7 includes a first mounting plate 701, an angle adjustment servo motor 702, a first cylinder 703, a second mounting plate 704, a rotating block 705, an angle adjustment mechanism belt 706, a positioning block 707, a first gear 708, a second gear 709 and a third gear 710. The first mounting plate 701 is fixedly connected to the second mounting plate 704 through a support rod. The first mounting plate 701 is fixedly installed with an angle adjustment servo motor 702 and a first cylinder 703. The output shaft of the angle adjustment servo motor 702 drives the rotating block 705 to rotate through the angle adjustment mechanism belt 706. The rotating block 705 is of a hollow structure, and the end of the rotating block 705 is rotatably connected to the second mounting plate 704. A positioning rod is inserted into the interior of the rotating block 705. The rotating block 705 can drive the positioning rod to rotate, and the positioning rod can move along the axis of the rotating block 705. The lower end of the positioning rod is rotatably connected to the output end of the first cylinder 703. The upper end of the positioning rod is eccentrically provided with a positioning block 707. The first gear 708 is eccentrically provided with a jack adapted to the positioning block 707. The first gear 708 meshes with the second gear 709, and the second gear 709 meshes with the third gear 710. The third gear 710 is used to drive the die head 5 to rotate.

[0051] The first gear 708 and the second gear 709 are rotatably installed on the conversion disk 3. The third gear 710 is fixedly installed between the limit ring 711 and the fixing ring 712. A connecting ring 713 is sleeved outside the limit ring 711, and the limit ring 711 is rotatably connected to the connecting ring 713. The upper end of the limit ring 711 is fixedly connected to the lower end of the die chassis 502, and the connecting ring 713 is fixedly connected to the conversion disk 3.

[0052] It further includes a positioning pin 714. The conversion disk 3 is provided with a through hole. The end of the positioning pin 714 is adapted to the jack on the first gear 708. When the device is in a stopped state, the positioning pin 714 is inserted into the jack to prevent the die head 5 from rotating.

[0053] The working process of the angle adjustment mechanism 7 is as follows: The first cylinder 703 is used to make the positioning block 707 engage or disengage with the first gear 708. After the positioning block 707 engages with the first gear 708, the angle adjustment servo motor 702 can be used to drive the rotating block 705 to rotate. The rotating block 705 drives the positioning rod to rotate, and finally the first gear 708 is driven to rotate through the positioning block 707. The first gear 708, the second gear 709 and the third gear 710 cooperate with each other to drive the die head 5 to rotate and adjust the angle of the die head 5 to ensure the smooth progress of the paper inserting operation.

[0054] The inlay mechanism includes a sleeve 201, a first servo motor 202, a first push plate 203, a first lead screw nut pair 204, a second servo motor 205, a second push plate 206, a second lead screw nut pair 207, a third servo motor 208, a first wire inlay rod mounting plate 209, a second wire inlay rod mounting plate 210, a first wire inlay rod 211, a second wire inlay rod 212, a third lead screw nut pair 213, a fourth servo motor 214, a fourth lead screw nut pair 215, a wire inlay limiting plate 216, and a support column 217. The first servo motor 202 and the second servo motor 205 are fixedly installed on the bottom plate 1. The first servo motor 202 drives the first push plate 203 to move in the vertical direction through the first lead screw nut pair 204. The second servo motor 205 drives the second push plate 206 to move in the vertical direction through the second lead screw nut pair 207. The second push plate 206 is located above the first push plate 203. The upper end of the second push plate 206 is fixedly installed with the first wire inlay rod mounting plate 209. And a third servo motor 208 is also installed on the second push plate 206. The third servo motor 208 drives the second wire inlay rod mounting plate 210 to move in the vertical direction through the third lead screw nut pair 213. The second wire inlay rod mounting plate 210 is located directly above the first wire inlay rod mounting plate 209. And the second wire inlay rod 212 is fixedly arranged on the second wire inlay rod mounting plate 210, and the first wire inlay rod 211 is fixedly arranged on the first wire inlay rod mounting plate 209. The second wire inlay rod 212 and the first wire inlay rod 211 are arranged alternately. The second wire inlay rod 212 and the first wire inlay rod 211 cooperate to form a ring, and the second wire inlay rod 212 and the first wire inlay rod 211 are adapted to the wire inlay channels 511 on the die head 5.

[0055] A fourth servo motor 214 is also installed on the first push plate 203. The fourth servo motor 214 is used to drive the fourth lead screw nut pair 215 to move. The fourth lead screw nut pair 215 is arranged along the axis of the first wire inlay rod mounting plate 209. The lower end of the fourth lead screw nut pair 215 extends below the bottom plate 1. The upper end of the fourth lead screw nut pair 215 is fixedly connected to the wire inlay limiting plate 216. Through grooves adapted to the second wire inlay rod 212 and the first wire inlay rod 211 are opened on the wire inlay limiting plate 216. A sleeve 201 is fixedly installed on the first wire inlay rod mounting plate 209. The sleeve 201 is sleeved outside the fourth lead screw nut pair 215.

[0056] The working process of the inlay mechanism is as follows: During the process of the first push plate 203 and the second push plate 206 rising at the same speed, they drive the first wire inlay rod mounting plate 209 and the sleeve 201 to rise to the designated position together. During this rising process, the fourth lead screw nut pair 215 will rise to the designated position synchronously with the sleeve 201.

[0057] After the fourth lead screw nut pair 215 ascends and jacks up the enameled wire in the die head 5 to reach the specified position in the motor stator 4 through the wire-embedded limit plate 216, the third servo motor 208 starts and drives the third lead screw nut pair 213 to lift, creating a drop between the second wire-embedding rod 212 and the first wire-embedding rod 211.

[0058] After that, the first push plate 203 and the second push plate 206 continue to lift together to the specified position under the driving action of the first servo motor 202 and the second servo motor 205. Then, the first push plate 203 completes the retraction action under the drive of the first servo motor 202. At this time, the fourth lead screw nut pair 215 needs to maintain its position. Since the fourth servo motor 214 is installed on the first push plate 203, the fourth servo motor 214 will drive the fourth lead screw nut pair 215 to rise synchronously. Therefore, the fourth servo motor 214 starts to reverse, keeping the top position of the fourth lead screw nut pair 215 relatively unchanged and stabilizing the enameled wire at a certain position in the motor stator 4.

[0059] Subsequently, under the drive of the second servo motor 205, the second push plate 206 drives the second wire-embedding rod 212 and the first wire-embedding rod 211 of the push rod seat 360 into the final position, that is, pushing the insulating paper and the interlayer slot cover paper into the stator. Then, the third servo motor 208 drives the third lead screw nut pair 213 to continue rising, pushing up the shorter paper to form a specified drop, thus completing the assembly.

[0060] After the assembly is completed, all servo motors retract to complete the reset and wait for the next round of assembly.

[0061] The operation process is as follows: First, the paper feeding mechanism 8 feeds paper to the empty die head 5. After the paper feeding is completed, the conversion disk driving motor 6 switches the conversion disk 3 to move the die head 5 loaded with paper strips above the paper-embedding mechanism and perform the paper-embedding mechanism operation.
