[0043] Example 1

[0044] Reference Figures 1 to 10, which is the first embodiment of the present invention, provides an automobile wire harness winding device, which includes a feeding component 100, a transfer component 200, a wire taking-up component 300 and a feeding component 400. The feeding component 100 includes a hopper 101, a drop tube 102 connected to the hopper 101, a buckle 103 arranged at the bottom of the drop tube 102, a spring 104 arranged in the buckle 103, and a wire drum 105 arranged in the hopper 101; the transfer component 200 includes a first motor 201, a rotating rod 202 connected to the first motor 201, a slider 203 arranged on the rotating rod 202, a slide groove 204 arranged outside the slider 203, a positioning block 205 arranged on the slide groove 204, a transfer rod 206 rotatably connected to the slide groove 204, and a spring 104 connected to the positioning block 205. a fixing plate 207 connected to the transfer rod 206, a gear 208 arranged on the transfer rod 206, and a tooth groove 209 arranged on the fixing plate 207; a wire taking-up assembly 300, including a first cylinder 301, a connecting rod 302 connected to the first cylinder 301, a push rod 303 connected to the connecting rod 302, a first gear 304 connected to the push rod 303, a second gear 305 meshing with the first gear 304, and a second motor 306 connected to the second gear 305; and a blanking assembly 400, connected to the push rod 303, including a second cylinder 401, a mounting frame 402 fixedly connected to the second cylinder 401, clamps 403 symmetrically arranged on both sides of the mounting frame 402, a control block 404 connected to the second cylinder 401, and a groove 405 opened on the clamp 403.

[0045] The output shaft of the first motor 201 is fixedly connected to the rotating rod 202, the slider 203 is rotatably connected to the end of the rotating rod 202, the slide 204 is straight, the slider 203 is arranged in the slide 204, the positioning block 205 is fixedly arranged on the back of the slide 204, the fixed plate 207 is provided with an embedding groove 207a, and the positioning block 205 is slidably connected to the embedding groove 207a. The transfer rod 206 penetrates the fixed plate 207 and is rotatably connected to the positioning block 205, the gear 208 is a half gear, the gear 208 is meshed with the tooth groove 209, and the transfer rod 206 is also provided with a soft plug 206a.

[0046] In order to load the wire bobbin 105, the wire bobbin 105 is placed in the hopper 101, and the wire bobbin 105 falls along the drop tube 102 and is arranged vertically. The buckle 103 set at the bottom of the drop tube 102 is opened by the spring 104 to limit the wire bobbin 105 and prevent the bottom wire bobbin 105 from rolling out from the opening 102a.

[0047] In order to move the bobbin 105 from the drop tube 102 to the fixture 403, starting the first motor 201 can rotate the rotating rod 202, and the rotating rod 202 drives the slider 203 to move in a circle, and the slider 203 is embedded in the slide groove 204. The slider 203 can move when it moves in a circle. Since a positioning block 205 is fixedly connected to the slide groove 204, the positioning block 205 slides in the embedding groove 207a, and the embedding groove 207a is set to be a straight line, that is, the positioning block 205 can only move forward and backward along the straight line. Therefore, the slide groove 204 is driven by the slider 203 and can only move forward and backward along the direction of the embedding groove 207a. The transfer rod 206 is also rotatably connected to the positioning block 205, so that the transfer rod 206 and the slide groove 204 move synchronously along the embedding groove 207a. When the transfer rod 206 moves from the leftmost end When it moves to the rightmost end, the gear 208 passes through the tooth groove 209, and the gear 208 rotates, driving the soft plug 206a on the transfer rod 206 to rotate 180 degrees toward the direction of the bobbin 105. When the transfer rod 206 moves to the rightmost end, the soft plug 206a approaches the bobbin 105 and is finally inserted into the bobbin 105. The first motor 201 continues to rotate, and the positioning block 205 moves in the opposite direction to take the bobbin 105 out of the opening 102a. During this period, the bobbin 105 squeezes the buckle 103 and compresses the spring 104. When the bobbin 105 is taken out, the buckle 103 is rebounded and reset by the spring 104, and the upper bobbin 105 falls back to the initial state. When the positioning block 205 moves from the rightmost end to the leftmost end, the bobbin 105 is also moved by the soft plug 206a and transferred from the drop tube 102 to the clamp 403. After the clamp 403 is clamped, the soft plug 206a is withdrawn from the wire barrel 105, and the transfer rod 206 continues to rotate 180 degrees and moves to the rightmost end to circulate, continuously taking material from the wire barrel 105.

[0048] Example 2

[0049] Reference Figures 1 to 15 , is the second embodiment of the present invention, which is different from the first embodiment in that: the telescopic end of the first cylinder 301 is fixedly connected to the connecting rod 302, the connecting rod 302 is symmetrically provided with protrusions 302a, the end of the push rod 303 is provided with a connecting groove 303a, the protrusion 302a is embedded in the connecting groove 303a, the side wall of the push rod 303 is symmetrically provided with strip grooves 303b, the inner wall of the first gear 304 is symmetrically provided with clamping strips 304a, the clamping strips 304a are correspondingly embedded in the strip grooves 303b, the first gear 304 is rotatably arranged in the extension direction of the first cylinder 301, and the output shaft of the second motor 306 is fixedly connected to the second gear 305.

[0050] Compared with Example 1, in order to clamp the bobbin 105, when the transfer rod 206 drives the bobbin 105 to approach the clamp 403, the first cylinder 301 is started to extend the telescopic end of the first cylinder 301, driving the push rod 303 to extend outward so that the clamp 403 can fix the bobbin 105. The strip groove 303b on the push rod 303 is embedded with a clamping strip 304a, so the movement of the push rod 303 does not cause the first gear 304 to rotate. In order to make the push rod 303 drive the bobbin 105 to wind the wire, the second motor 306 is started, and the second motor 306 drives the second gear 305 to rotate, and the first gear 304 is meshed with the second gear 305. Since the clamping strip 304a is embedded in the strip groove 303b, the first gear 304 is meshed with the second gear 305. 03b, the clamping strip 304a can make the first gear 304 drive the push rod 303 to rotate. In order to prevent the rotation of the push rod 303 from affecting the telescopic end of the first cylinder 301, the protrusion 302a on the connecting rod 302 is embedded in the connecting groove 303a. The rotation of the push rod 303 does not cause the connecting rod 302 to rotate. The rotation of the push rod 303 can drive the blanking component 400 fixed at the end to rotate synchronously, that is, the wire reel 105 clamped by the clamp 403 rotates synchronously. A wire clamping groove 105a is provided on the wire reel 105. After the wire reel 105 is clamped, the wire harness head can be clamped into the wire clamping groove 105a manually or by a mechanical arm. After that, the wire reel 105 rotates through the above scheme, and the winding of the wire harness can be completed by continuously winding the wire.

[0051] The remaining structures are the same as those of Example 1.

[0052] Example 3

[0053] Reference Figures 1 to 21 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the end of the push rod 303 away from the connecting groove 303a is fixedly provided with the second cylinder 401, the telescopic end of the second cylinder 401 is fixedly connected to the control block 404, the mounting frame 402 is provided with an embedding hole 402a, the clamp 403 is inserted into the embedding hole 402a, and a transverse groove 402b is provided on the inner wall of the embedding hole 402a. The clamp 403 is also provided with a moving block 403a, and the moving block 403a is symmetrically provided with horizontal bars 403b on the upper and lower surfaces, and the horizontal bars 403b are correspondingly embedded in the transverse groove 402b, and a trapezoidal groove 403c is also provided on the opposite side of the two moving blocks 403a. The side wall of the control block 404 is symmetrically provided with trapezoidal blocks 404a, and the trapezoidal blocks 404a are embedded in the trapezoidal groove 403c. The bottom of the unloading assembly 400 is also provided with a discharge slide 406.

[0054] Compared with Example 2, in order to fix the bobbin 105 sent by the transfer rod 206, when the transfer rod 206 is close to the clamp 403, the first cylinder 301 pushes the clamp 403 out of the bobbin 105 close to the transfer rod 206. When the transfer rod 206 moves to the leftmost end, the second cylinder 401 is started, and the telescopic end of the second cylinder 401s retracts and retracts the control block 404. When the trapezoidal block 404a retracts, the trapezoidal groove 403c is continuously tightened, that is, the moving blocks 403a are close to each other, and a transverse groove 402b is also provided in the embedding hole 402a of the mounting frame 402. The horizontal bar 403b on the moving block 403a is embedded in the transverse groove 402b, so the moving block 403a can only move along the transverse groove 40 2b extension direction, that is, the moving blocks 403a are close to each other along the transverse groove 402b in the mounting frame 402, driving the clamps 403 to be close to each other in the embedding hole 402a until the wire bobbin 105 is clamped, and then the transfer rod 302 moves to the right, first driving the soft plug 206a to pull out the wire bobbin 105, and then reverses the direction to cyclically take out the wire bobbin 105; after clamping the wire bobbin 105, the telescopic end of the first cylinder 301 is recovered, so that the clamp 403 retracts to the initial position, and then the wire bobbin 105 is rotated by the wire taking-up assembly 300 to take up the wire, and after the wire taking-up is completed, the second cylinder 401 moves in the opposite direction to release the clamp 403, and the wire bobbin 105 falls into the discharge slide 406 for discharge, and is automatically transported and transferred with the collected wire harness.

[0055] The remaining structure is the same as that of Example 2.
