Description

Technical Field

[0001] The present invention belongs to the field of intelligent manufacturing of automobiles, and particularly relates to a flat wire peeling device with multi-linkage wire dragging and a stator wire forming system. Background Art

[0002] The new energy vehicle industry is booming at an unprecedented speed. As one of the core components of new energy vehicles, the performance of the drive motor directly affects the power performance, economy, and cruising range of the whole vehicle. In recent years, flat wire motors have gradually become the first 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, for the wiring, pin, I-pin, Hair-pin, X-pin of the stator, which are collectively referred to as stator wires in this application, how to efficiently and accurately remove the paint from the wire ends is a technical problem. Traditional manufacturing methods such as manual wire feeding, skin cutting, or laser paint removal have problems such as low production efficiency, difficulty in ensuring the qualification rate of stators, and instability in the four sides of wire end paint removal. This is mainly caused by the unstable support of the flat wire before and after the paint removal station during the wire transmission process, resulting in problems such as uneven and asymmetric wire end paint removal, excessive paint removal on one side and less paint removal on the other side; moreover, with different lengths of flat wire peeling or different paint removal positions, the wire dragging position cannot change accordingly, and manual adjustment leads to a reduction in production efficiency. Therefore, developing an efficient and accurate intelligent stator wire end paint removal device is of great significance for improving the manufacturing quality and production efficiency of flat wire motors.

[0015] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0016] It should be understood that the "system", "device", "unit" and / or "module" used in this specification is a method for distinguishing different components, elements, parts, portions or assemblies at different levels. However, if other words can achieve the same purpose, the described words can be replaced by other expressions.

[0017] Flat wire stripping device A flat wire peeling device with cable-dragging multi-linkage, see Figure 1 - Figure 7 , the flat wire peeling device includes a three-link drive module 100, two guide cable-dragging modules 200, a multi-head paint-removing module 400, a paint and ash suction module 500 and an alignment and cleaning module 600 arranged on a peeling frame 300.

[0018] The two guide cable-dragging modules 200 are arranged on the front and rear sides of the peeling frame 300, and are both mounted on the sliding top plate of the three-link drive module 100 at the bottom.

[0019] Among them, the three-link drive module 100 includes a linkage driver 110, a wire-dragging sliding base 120 that is connected to the upper part of the wire-guiding module 200, a paint-removing sliding base 130 that is connected to the upper part of the paint-removing frame 300, and a variable-spacing link group 140; both ends of the bottom of the wire-dragging sliding base 120 and the paint-removing sliding base 130 are slidably arranged on the variable-spacing linkage rail module 150. Both ends of the variable-spacing link group 140 are fixed, and the middle part is connected to the wire-dragging sliding base 120 and the paint-removing sliding base 130 through a linkage column 141. The bottom of the paint-removing sliding base 130 is also connected to the driving movable end of the linkage driver 110. When the linkage driver 110 drives, it linkage-adjusts the distance between the two wire-guiding modules 200 and the paint-removing frame 300.

[0020] Specifically, the linkage driver 110 uses a linear motor, and the mover of the linear motor is connected to the bottom surface or side surface of the paint-removing sliding base 130. Of course, it can also use methods such as cylinder drive, motor screw drive, motor belt or motor chain drive, etc. Here, a linear motor is preferably used.

[0021] The variable-spacing link group 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, and the inner section of the multi-link telescopic body 142 is connected to the wire-dragging sliding base 120 and the paint-removing sliding base 130 through the linkage column 141.

[0022] The illustrated example is a three-linkage. Of course, it can also be a two-linkage, that is, only one wire-guiding module 200 and the paint-removing frame 300 are provided, and the two-linkage automatically adjusts the distance between the two.

[0023] Among them, the wire-guiding module 200 includes a guiding adjustment seat 210, a wire-groove block 220, and a wire-guiding installation vertical plate 230. The wire-groove block 220 is connected to the top of the wire-guiding installation vertical plate 230 through the guiding adjustment seat 210.

[0024] A guide groove is opened at the top of the wire-groove block 220 for the support and guidance of flat wires. Specifically, the wire-groove block 220 is made of copper.

[0025] Among them, the multi-head paint-removing module 400 includes multiple groups of paint-removing heads 410, a paint-removing adjustment component 420, a paint-removing detection camera 430, and a paint-removing adapter seat 440; the paint-removing heads 410 are installed on the paint-removing adapter seat 440 through the paint-removing adjustment component 420, and the paint-removing detection camera 430 is installed on the paint-removing adapter seat 440 or the paint-removing head 410. The entire multi-head paint-removing module 400 is installed on the paint-removing frame 300 through the paint-removing adapter seat 440.

[0026] Among them, the paint stripping head 410 uses a laser, including a laser light source body and a laser transmission lens module. Referring to the attached drawings, the laser transmission lens emits the laser of the laser light source body and then passes through the processing window to strip the paint from the head of the flat wire by laser.

[0027] The paint stripping adjustment assembly 420 uses linear and angular sliding tables, etc., or can also be in the form of other fine-tuning motors, etc., and is used to adjust the position and angle of the paint stripping head 410.

[0028] The paint stripping detection camera 430 is used to detect the paint stripping effect after the head of the flat wire is processed by the paint stripping head 410.

[0029] Of course, a purging unit can also be set at the paint stripping detection camera 430 to prevent the lens from getting dirty.

[0030] In the illustrated example, four groups of paint stripping heads 410, paint stripping adjustment assemblies 420, paint stripping detection cameras 430, and paint stripping adapter seats 440 are used to perform laser processing on the four sides of the head of the flat wire respectively.

[0031] Among them, the powers of the four groups of paint stripping heads 410 are different. In the case where symmetric paint stripping of the head of the flat wire is required, the powers of the two opposite paint stripping heads 410 are the same. In one example, the powers of the upper and lower paint stripping heads 410 are greater than those of the left and right ones, so as to achieve the processing effect of a flat head rather than a square head.

[0032] Among them, the paint dust absorption module 500 includes a processing shield 510, multiple dust suction branch pipes 520, a dust suction main pipe 530, and an external dust collector and a suction fan. A wire transmission hole is opened in the middle of the processing shield 510, and a processing window is opened on the side. The multiple dust suction branch pipes 520 are connected to the processing shield 510 in a direction intersecting with the processing direction of the multi-head paint stripping module 400. The multiple dust suction branch pipes 520 are aggregated through the dust suction main pipe 530 at the top of the paint stripping rack 300 and then connected to the external dust collector.

[0033] Among them, the guiding and cleaning module 600 includes a guiding groove block 620 installed on the guiding installation bottom plate 610, two groups of correction wheel sets 630 arranged vertically front and back, and a brush chamber 640; the flat wire after paint stripping passes through the correction wheel sets 630 and then passes through the brush chamber 640, and the surface of the copper wire is cleaned by the brushes in the chamber.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
