Description

Technical Field

[0001] This invention belongs to the field of intelligent automotive manufacturing, specifically relating to a flat wire peeling device with multi-linkage of a dragline and a stator wire forming system. Background Technology

[0002] The new energy vehicle industry is booming at an unprecedented pace. As one of the core components of new energy vehicles, the performance of the drive motor directly affects the vehicle's power, economy, and driving range. In recent years, flat-wire motors have gradually become the preferred choice for new energy vehicle drive motors due to their high power density, high efficiency, low noise, and good heat dissipation performance.

[0003] However, in the manufacturing process of flat wire motors, the stator wires (pins, I-pins, hair-pins, and X-pins, collectively referred to as stator wires in this application) present a significant technical challenge in efficiently and accurately removing the enamel from their ends. Traditional manufacturing methods, such as manual wire feeding, shearing, or laser enamel removal, suffer from low production efficiency, difficulty in guaranteeing stator pass rates, and instability in enamel removal on all four sides. This is primarily due to the unstable support of the flat wires before and after the enamel removal station during the wire feeding process, resulting in uneven and asymmetrical enamel removal, with some areas receiving more enamel than others. Furthermore, the wire pulling position cannot be adjusted according to the different shearing or enamel removal positions of flat wires of varying lengths, leading to reduced production efficiency due to manual adjustments. Therefore, developing an efficient, precise, and intelligent stator wire end enamel removal device is of great significance for improving the manufacturing quality and production efficiency of flat wire motors. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a flat wire peeling device and a stator wire forming system with multiple linkages for dragging wires, which can solve the above-mentioned problems.

[0005] A multi-linkage flat wire stripping device includes a three-linkage drive module, two guide wire-carrying modules, a multi-head paint removal module and a paint dust absorption module mounted on a stripping frame; the two guide wire-carrying modules are located on the front and rear sides of the stripping frame, and are both mounted on the sliding top plate of the three-linkage drive module at the bottom.

[0006] Furthermore, the three-linkage drive module includes a linkage driver, a cable-carrying sliding base connected to the upper guide cable-carrying module, a tare sliding base connected to the upper tare frame, and a variable-pitch linkage assembly. The cable-carrying sliding base and the tare sliding base are slidably mounted on the variable-pitch linkage slide rail module at both ends. The variable-pitch linkage assembly is fixed at both ends and connected to the cable-carrying sliding base and the tare sliding base in the middle through a linkage column. The bottom of the tare sliding base is also connected to the drive movable end of the linkage driver. When the linkage driver is driven, it adjusts the distance between the two guide cable-carrying modules and the tare frame in a linkage manner.

[0007] Furthermore, the guide cable support module includes a guide adjustment seat, a cable support groove block, and a cable support mounting plate, wherein the cable support groove block is connected to the top of the cable support mounting plate through the guide adjustment seat.

[0008] Furthermore, the multi-head paint stripping module includes multiple paint stripping heads, a paint stripping adjustment component, a paint stripping detection camera, and a paint stripping adapter. The paint stripping heads are installed to the paint stripping adapter via the paint stripping adjustment component, and the paint stripping detection camera is installed to the paint stripping adapter or the paint stripping head. The entire multi-head paint stripping module is installed to the peeling frame via the paint stripping adapter.

[0009] Furthermore, the paint dust absorption module includes a processing cover, multiple suction pipes, a main suction pipe, and an external dust collector and exhaust fan. The processing cover has a cable feed hole in the middle and a processing window on the side. The multiple suction pipes are connected to the processing cover in a cross direction with the processing direction of the multi-head paint stripping module. The multiple suction pipes are connected to the external dust collector after being gathered at the top of the peeling frame through the main suction pipe.

[0010] Furthermore, the flat wire stripping device also includes a guiding and cleaning module, which includes a guide groove block installed on the guiding mounting base plate, two sets of straightening wheels arranged vertically front and back, and a brush chamber; after stripping, the flat wire passes through the straightening wheels and then through the brush chamber for copper wire surface cleaning.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Flat wire peeling device

[0029] A multi-linkage flat wire stripping device, see [link / reference]. Figures 1-7 The flat wire peeling device includes a three-linkage drive module 100, two guide wire support modules 200, a multi-head paint removal module 400, a paint dust absorption module 500, and a guiding and cleaning module 600, all mounted on the peeling frame 300.

[0030] Two guide wire support modules 200 are located on the front and rear sides of the peeling frame 300, and both are installed at the bottom onto the sliding top plate of the three-linkage drive module 100.

[0031] The three-linkage drive module 100 includes a linkage driver 110, a cable-carrying sliding base 120 connected to the upper part of the guide cable-carrying module 200, a peeling sliding base 130 connected to the upper part of the peeling frame 300, and a variable-pitch linkage group 140. The cable-carrying sliding base 120 and the peeling sliding base 130 are slidably mounted on the variable-pitch linkage slide rail module 150 at both ends. The variable-pitch linkage group 140 is fixed at both ends and connected to the cable-carrying sliding base 120 and the peeling sliding base 130 in the middle through a linkage column 141. The bottom of the peeling sliding base 130 is also connected to the drive movable end of the linkage driver 110. When the linkage driver 110 is driven, the distance between the two guide cable-carrying modules 200 and the peeling frame 300 is adjusted in linkage.

[0032] Specifically, the linkage driver 110 uses a linear motor, and the mover of the linear motor is connected to the bottom or side of the peeling sliding base 130. Of course, cylinder drive, motor screw drive, motor belt or motor chain drive can also be used, but a linear motor is preferred here.

[0033] The variable pitch linkage assembly 140 includes a linkage column 141, a multi-link telescopic body 142 composed of multiple links, and an end fixing column 143. The end fixing column 143 is used to fix the multi-link telescopic body 142 from the outer end. The inner section of the multi-link telescopic body 142 is connected to the cable sliding base 120 and the peeling sliding base 130 through the linkage column 141.

[0034] The illustration shows a three-linkage system. Of course, it can also be a two-linkage system, that is, only one guide cable module 200 and peeling frame 300 are set, and the two-linkage system automatically adjusts the distance between them.

[0035] The guide cable support module 200 includes a guide adjustment seat 210, a cable support groove block 220, and a cable support mounting plate 230. The cable support groove block 220 is connected to the top of the cable support mounting plate 230 through the guide adjustment seat 210.

[0036] A guide groove is formed on the top of the wire support block 220 for supporting and guiding the flat wire. Specifically, the wire support block 220 is made of copper.

[0037] The multi-head paint stripping module 400 includes multiple paint stripping heads 410, a paint stripping adjustment component 420, a paint stripping detection camera 430, and a paint stripping adapter 440. The paint stripping heads 410 are installed onto the paint stripping adapter 440 via the paint stripping adjustment component 420, and the paint stripping detection camera 430 is installed onto the paint stripping adapter 440 or the paint stripping head 410. The entire multi-head paint stripping module 400 is installed onto the peeling frame 300 via the paint stripping adapter 440.

[0038] The paint removal head 410 employs a laser, comprising a laser source and a laser transmission lens module. Referring to the attached diagram, the laser transmission lens directs the laser emitted from the laser source through a processing window to remove paint from the flat wire head.

[0039] The paint removal adjustment component 420 can be a linear or angular slide, or other fine-tuning motors, used to adjust the position and angle of the paint removal head 410.

[0040] The paint removal inspection camera 430 is used to inspect the peeling effect of flat wire ends after processing by the paint removal head 410.

[0041] Of course, a purging unit can also be installed at the paint removal inspection camera 430 to prevent the lens from getting dirty.

[0042] As illustrated, four sets of paint removal heads 410, a paint removal adjustment component 420, a paint removal detection camera 430, and a paint removal adapter 440 are used to perform laser processing on the four sides of the flat wire head, respectively.

[0043] Among them, the four sets of paint removal heads 410 have different powers. When symmetrical flat wire head paint removal is required, the two opposite paint removal heads 410 have the same power. In one example, the power of the top and bottom paint removal heads 410 is greater than that of the left and right sides, thus achieving the processing effect of flat head rather than square head.

[0044] The paint dust absorption module 500 includes a processing cover 510, multiple suction pipes 520, a main suction pipe 530, and an external dust collector and exhaust fan. The processing cover 510 has a cable feeding hole in the middle and a processing window on the side. The multiple suction pipes 520 are connected to the processing cover 510 in a cross direction with the processing direction of the multi-head paint stripping module 400. The multiple suction pipes 520 are collected at the top of the peeling frame 300 through the main suction pipe 530 and then connected to the external dust collector.

[0045] The guiding and cleaning module 600 includes a guide groove block 620 installed on the guiding mounting base plate 610, two sets of straightening wheel sets 630 arranged vertically in front and behind, and a brush chamber 640; after peeling, the flat wire passes through the straightening wheel set 630 and then through the brush chamber 640, and the copper wire surface is cleaned by the brush inside the chamber.

[0046] Stator wire forming system

[0047] Not shown in the figure, the stator wire forming system includes a flat wire feeding module, a flat wire peeling device, a wire cutting module, a flat wire 2D forming device, a flat wire peeling device, a flat wire 3D forming device, a wire type optical inspection mechanism, a carbon brush inspection mechanism, and a feeding and receiving mechanism.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
