Description

Technical Field

[0001] This utility model belongs to the field of wire harness assembly technology, and in particular relates to an automatic wire harness loading machine. Background Technology

[0002] Against the backdrop of exponential growth in demand for AI computing power, high-speed data transmission harnesses, serving as the "nerve vessels" connecting chips, servers, and data centers, directly impact signal integrity and system reliability through their assembly precision and efficiency. Traditional manual clamping methods suffer from low efficiency and poor consistency; therefore, automated harness clamping equipment has become a critical technological requirement in the industry.

[0003] Wire harnesses are typically supplied in rolls, which need to be cut to a set length, then bent into a U-shape, and finally have terminals welded to the ends. Existing technologies, such as the automated wire harness clamp assembly machine disclosed in Chinese Utility Model Patent Publication No. CN222404289U, can perform U-shaped clamping on wire harnesses, but it can only clamp one wire harness at a time. This not only results in low work efficiency, but also makes it impossible to assemble multiple parallel U-shaped wire harnesses simultaneously within a single product. Furthermore, this solution can only clamp wire harnesses that have already been cut to a set length; it cannot cut entire rolls of material to the set length.

[0004] Therefore, it is necessary to provide an automatic wire harness loading machine to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0018] Please refer to Figures 1-13 This embodiment is an automatic wire harness feeding machine 100, which includes: The wire harness feeding device 1 includes a feeding assembly 11 and a cutting module 13; The feeding device 2 includes a first clamping module 23, a second clamping module 26, a first driving member 21 and a second driving member 24. The first driving member 21 drives the first clamping module 23 and the second clamping module 26 to move simultaneously in a first direction, and the second driving member 24 drives the second clamping module 26 to move along a second direction. The first direction is perpendicular to the second direction. The U-type device 3 includes a first U-type mechanism 31 and a first U-type mechanism 31; Locking module 5; The clamp conveying device 4 includes a loading conveyor line 41, a unloading conveyor line 42, and a transfer positioning mechanism 43 located at one end of the loading conveyor line 41 and the unloading conveyor line 42.

[0019] The feeding assembly 11 includes a feeding rack 111, several roll frames 112 arranged on the side of the feeding rack 111, and a first motor 113 that drives the roll frames 112 to rotate. The first motor 113 is mounted on the feeding rack 111, and the wire harness rolls are sleeved on the roll frames 112 and rotate together with the roll frames 112. The cutting module 13 includes a cutter 131 and a cutting support plate 132 that cooperate with each other. Both the cutter 131 and the cutting support plate 132 are driven by a first cylinder 133 to move up and down. When the cutter 131 moves downward to cut, the cutting support plate 132 moves upward and supports the bottom of the wire harness. A guide mechanism 12 and a clamping assembly 14 are also provided between the feeding assembly 11 and the cutting module 13. The cutting module 13 and the clamping assembly 14 are mounted together on a first support frame 15. The clamping assembly 14 includes a clamping cylinder 141 and a pair of clamping rods 142 driven by the clamping cylinder 141 to open or clamp. One clamping rod 142 has several grooves that conform to the shape of the wire harness, and the other clamping rod 142 has several corresponding ribs. The wire harness is positioned in the grooves, and the ribs clamp the wire harness to achieve precise positioning. In this embodiment, two clamping assemblies 14 are provided along the length of the wire harness to ensure clamping stability. In other embodiments, the number of clamping assemblies 14 can be set according to the actual situation. The guiding mechanism 12 includes several support columns 121, a wire block 122 that is movably mounted on the support columns 121, a first sensor 125 located below the wire block 122, and several guide wheel sets 123. The wire block 122 is provided with a clearance through hole 124 for the wire harness to pass through. The first sensor 125 is used to sense the position of the wire block 122. When the first sensor 125 can detect the wire block 122, the wire block 122 is in a low position, and it is determined that the length of the wire bundle released from the wire bundle roll is sufficient, and the feeding stops. If the first sensor 125 cannot detect the wire block 122, the wire block 122 is in a high position, and it is determined that the length of the wire bundle released from the wire bundle roll is insufficient, and the feeding should start.

[0020] The movable end of the first driving member 21 is connected to the first support plate 22. The first clamping module 23 is connected to one end of the first support plate 22 and is close to the cutting module 13. The second driving member 24 is disposed on the first support plate 22, and the movable end of the second driving member 24 is connected to the second support plate 25. The second clamping module 26 is disposed on the second support plate 25. The first clamping module 23 includes a second cylinder 231, a third support plate 232 driven by the second cylinder 231 to move along a first direction, and a first clamping unit 233 disposed on the third support plate 232. The second clamping module 26 includes a first rotary motor 261, a fourth support plate 262 driven by the first rotary motor 261 to rotate around a second direction, and a second clamping unit 263 disposed on the fourth support plate 262. The first direction is perpendicular to the second direction. In this embodiment, the first direction is the Y direction, and the second direction is the X direction.

[0021] The first clamping unit 233 and the second clamping unit 263 have the same or similar structures, and both include a base 2331, a sliding plate 2332 slidably disposed on the base 2331, a third cylinder 2333 driving the sliding plate 2332 to slide along a third direction, a pair of sliding blocks 2334 slidably disposed on the base 2331 along a fourth direction, and a pair of first grippers 2335 disposed on the pair of sliding blocks 2334. Each sliding block 2334 is fixedly provided with a cam 2336, and the base 2331 is provided with a first gripper 2335 along the fourth direction. A set of first sliding grooves 2337 extending in a certain direction is provided on the sliding plate 2332, and a set of second sliding grooves 2338 are provided on the sliding plate 2332. The second sliding grooves 2338 are roughly "V" shaped. One end of the cam 2336 extends into both the first sliding groove 2337 and the second sliding groove 2338. When the third cylinder 2333 drives the sliding plate 2332 to move in a third direction, it can drive the cam 2336 to move closer or further away from each other in a fourth direction within the first sliding groove 2337, thereby realizing the opening or clamping action of a pair of first grippers 2335. The base 2331 is provided with a first guide groove 2339 for the sliding plate 2332 to slide and a second guide groove 23310 for the sliding block 2334 to slide. One of the first grippers 2335 is provided with several grooves that conform to the shape of the wire harness, and the other first gripper 2335 is provided with several corresponding ribs. The wire harness is positioned in the groove, and the ribs press the wire harness to achieve precise positioning of the wire harness.

[0022] The third direction is perpendicular to the fourth direction, and the fourth direction is the Z direction, so that the pair of first grippers 2335 can open or close vertically. The structure of the first gripping unit 233 is similar to that of the second gripping unit 263, the difference being that the arrangement directions of the first gripping unit 233 and the second gripping unit 263 are different. The first gripping unit 233 is arranged along the Y direction, so the third direction at the location of the first gripping unit 233 is the Y direction. The second gripping unit 263 is arranged along the X direction, so the third direction at the location of the second gripping unit 263 is the X direction.

[0023] The first U-shaped mechanism 31 and the second U-shaped mechanism 32 have the same structure and both include a third driving member 318, a fifth support plate 311 driven by the third driving member 318 to move in the X direction, a second rotary motor 312 mounted on the fifth support plate 311, a rotary plate 313 driven by the second rotary motor 312 to rotate around the Z axis, a fourth cylinder 314 fixed on the rotary plate 313, and a pair of second grippers 315 driven by the fourth cylinder 314 to open or clamp. One of the second grippers 315 is provided with several grooves that conform to the shape of the wire harness, and the other second gripper 315 is provided with several corresponding ribs. The wire harness is positioned in the grooves, and the ribs press the wire harness to achieve precise positioning of the wire harness. The second rotary motor 312 drives the rotating plate 313 to rotate 90° around the Z-axis. To avoid over-rotation, a first limiting post 316 and a second limiting post 317 are provided on the side of the rotating plate 313. The first limiting post 316 and the second limiting post 317 are both installed on the fifth support plate 311. The first limiting post 316 extends along the X direction and the second limiting post 317 extends along the Y direction. Before rotation, the rotating plate 313 is restricted on the first limiting post 316. After the rotating plate 313 rotates 90°, the rotating plate 313 is restricted on the second limiting post 317. The first limiting post 316 and the second limiting post 317 are provided to ensure that the rotation angle of the rotating plate 313 is exactly 90°, so as to ensure the rotation accuracy.

[0024] Each pair of clamping rods 142, first jaws 2335, and second jaws 315 is equipped with several grooves and several ribs, enabling the simultaneous clamping of multiple wire harnesses and achieving a U-shaped action for multiple wire harnesses at the same time, thus improving work efficiency. Moreover, each pair of clamping rods 142, first jaws 2335, and second jaws 315 is equipped with detachable fasteners, such as screws, bolts, and pins. If a wire harness of a different size is to be replaced, the fasteners can be loosened and replaced with clamping rods 142, first jaws 2335, and second jaws 315 that are compatible with the wire harness. This provides good flexibility and adaptability to different sizes of wire harnesses, improving the versatility of the wire feeding machine.

[0025] The locking module 5 includes a locking member 51 and a locking drive member 52 that drives the locking member 51 to move up and down and rotate simultaneously. Both the locking member 51 and the locking drive member 52 are existing technologies, and their designs are readily available and will not be elaborated upon here. In this embodiment, the U-shaped device 3 and the locking module 5 are jointly mounted on a gantry frame 6. The first U-shaped mechanism 31 and the second U-shaped mechanism 32 are located at both ends of the gantry frame 6, and are either close to or far apart from each other along the length of the gantry frame 6. The locking module 5 is located between the first U-shaped mechanism 31 and the second U-shaped mechanism 32. In other embodiments, the specific layout of the first U-shaped mechanism 31, the second U-shaped mechanism 32, and the locking module 5 can be set according to actual conditions and is not limited here.

[0026] The fixture transfer and positioning mechanism 43 includes a first transfer unit 431 that is connected to the loading conveyor line 41, a second transfer unit 432 that is connected to the unloading conveyor line 42, a transfer unit 433 disposed between the first transfer unit 431 and the second transfer unit 432, and a push component 434 that pushes the fixture 200 on the first transfer unit 431 to the transfer unit 433. The loading conveyor line 41 and the unloading conveyor line 42 are arranged vertically at intervals. The first transfer unit 431 includes a first Z-axis drive member 4311 and a first positioning seat 4312 driven by the first Z-axis drive member 4311 to move along the Z direction. The first positioning seat 4312 is provided with a positioning sliding groove 4313 for supporting the clamp 200 and allowing the clamp 200 to slide. The pushing component 434 is located at one end of the first positioning seat 4312, and a limiting piece 4314 is provided at the end of the first positioning seat 4312 near the pushing component 434. When the clamp 200 on the feeding conveyor line 41 moves onto the first positioning seat 4312, the limiting piece 4314 can prevent the clamp 200 from falling off the other end of the first positioning seat 4312. A first supporting block 4315 is provided on one side of the clamp 200, and a fifth cylinder 4316 is provided to drive the first supporting block 4315 to move horizontally. A positioning groove 206 is provided on the side of the clamp 200 to cooperate with the first supporting block 4315. The first supporting block 4315 and the positioning groove 206 are engaged in supporting cooperation. When the first positioning seat 4312 rises, it can restrict the movement of the clamp 200 in the horizontal direction. The pushing assembly 434 includes a pushing cylinder 4341 and a pushing rod 4342 connected to the output shaft end of the pushing cylinder 4341. The movement direction of the first supporting block 4315 is perpendicular to the movement direction of the pushing rod 4342.

[0027] The second transfer unit 432 includes a first Y-axis drive member 4321, a sixth support plate 4322 driven by the first Y-axis drive member 4321 to move along the Y direction, a second Z-axis drive member 4323 disposed on the sixth support plate 4322, a seventh support plate 4324 driven by the second Z-axis drive member 4323 to move along the Z direction, and a second positioning seat 4325 and a positioning assembly 4326 disposed on the seventh support plate 4324. The positioning assembly 4326 is located below the second positioning seat 4325. The second positioning seat 4325 is also provided with a positioning sliding groove 4313 for supporting the clamp 200 and allowing the clamp 200 to slide. A second supporting block 4327 is provided on one side of the second positioning seat 4325, which supports the side of the clamp 200, and a sixth cylinder 4328 for driving the second supporting block 4327 to move horizontally. The function of the second supporting block 4327 is the same as that of the first supporting block 4315, and will not be described again here. The positioning component 4326 includes a positioning cylinder 43261 and a positioning pin 43262 driven by the positioning cylinder 43261 to move up and down. The positioning pin 43262 passes through the second positioning seat 4325 and extends into the bottom of the clamp 200 to achieve the positioning of the clamp 200, ensuring the accuracy of the subsequent positioning of the wire harness into the clamp 200 and the tightening of the screws. The second positioning seat 4325 is provided with a clearance through hole for the positioning pin 43262 to move up and down, and the clamp 200 is provided with a positioning hole for the positioning pin 43262 to extend into.

[0028] A visual inspection camera 45 is provided on one side of the second transfer unit 432. The detection light of the visual inspection camera 45 is directed towards the movement path of the second transfer unit 432, so that the second transfer unit 432 can take pictures and inspect the clamp 200 on the second positioning seat 4325 during the up and down movement of the second transfer unit 4325. When the second positioning seat 4325 rises, it detects whether the clamp 200 is qualified. When the second positioning seat 4325 falls, it detects the bending of the wire harness on the clamp 200 and whether the screw tightening is qualified. The second transfer unit 432 is located directly below the locking module 5. After the second transfer unit 432 rises to the position, it facilitates the screw tightening action.

[0029] The transfer unit 433 includes a support base 4331 and a third positioning base 4332 fixed on the support base 4331.

A third supporting block 4333 is provided on one side of the third positioning base 4332, which supports the side of the clamp 200, and a seventh cylinder 4334 for driving the third supporting block 4333 to move horizontally. The function of the third supporting block 4333 is the same as that of the first supporting block 4315, and will not be described again here. The height of the third positioning base 4332 is the same as the height of the unloading conveyor line 42.

[0030] The first positioning seat 4312, the third positioning seat 4332, and the second positioning seat 4325 are located on the same straight line and are connected to each other. When the first positioning seat 4312, the third positioning seat 4332, and the second positioning seat 4325 are at the same height, the pushing component 434 pushes the clamp on the first positioning seat 4312 onto the third positioning seat 4332. At the same time, the clamp on the third positioning seat 4332 is pushed onto the second positioning seat 4325, and the clamp 200 on the second positioning seat 4325 is pushed onto the unloading conveyor line 42. The end of the loading conveyor line 41 is provided with a blocking component 44, which includes a second sensor 441, a blocking plate 442, and an eighth cylinder 443 that drives the blocking plate 442 to move up and down. In this embodiment, a blocking component 44 is also provided at the end of the feeding conveyor 42 to facilitate the removal of the clamp. In other embodiments, no blocking component 44 is provided at the end of the feeding conveyor 42, and the clamp 200 clamping several wire bundles flows directly to the subsequent workstation for subsequent operations.

[0031] The clamp 200 includes a clamp base 201 and a clamp top cover 202. The clamp base 201 has several grooves that conform to the shape of the wire harness and support it. The clamp top cover 202 has several corresponding ribs that press against the upper surface of the wire harness. An elastic element 203 is located at the midpoint between the clamp base 201 and the clamp top cover 202. A clearance space 204 is formed between the clamp base 201 and the clamp top cover 202 to allow the wire harness to enter. A screw 205 is screwed into the center of the clamp top cover 202. Each of the two clamping jaws 315 is provided with threaded holes. A clearance channel 319 for the clamp 200 is provided in the middle of the second clamping jaw 315. The width of the clearance channel 319 is greater than the width of the clamp 200, so that the two pairs of second clamping jaws 315 can grip the wire harness and enter the clearance space 204 from both sides, thereby securing the wire harness into the groove of the clamp. The locking module 5 tightens the screws 205 onto the clamp base 201, assembling the clamp base 201 and the clamp top cover 202 together, thus pressing and positioning the wire harness on the clamp 200, facilitating subsequent processing of the wire harness. The clamp base 201 has a positioning groove on its side. Correspondingly, the first positioning seat 4312, the third positioning seat 4332, and the second positioning seat 4325 have positioning protrusions at the positioning sliding groove 4313. The cooperation between the positioning groove and the positioning protrusions restricts the movement of the clamp 200 in the Z direction.

[0032] When using the automatic wire harness feeding machine 100 provided in this solution, the wire harness roll is placed on the reel frame 112. Several wire harnesses pass sequentially through the clearance through hole 124, guide wheel group 123, clamping assembly 14, and cutting module 13. The second driving member 24 drives the second clamping module 26 to move along the X direction to the cutting module 13. The first gripper 2335 of the second clamping module 26 clamps the wire harness. The second driving member 24 drives the second clamping module 26 to move in the opposite direction along the X direction, pulling the wire harness out to a set length. Then, the clamping assembly 14 clamps the wire harness. At the same time, the second cylinder 231 of the first clamping unit 233 drives the third support plate 232 to drive the first gripper 2335 to extend along the Y direction to clamp the wire harness. The cutting module 13 cuts the wire harness. At this time, the first clamping unit 233 and the second clamping module 26 clamp the left and right ends of the wire harness. The first rotary motor 261 drives the fourth support plate 262 to rotate the second clamping module 26 180°. Then, the first driving member 21 drives the first support plate 22 to move the first clamping unit 233 and the second clamping module 26 along the Y direction to deliver the wire harness to the U-shaped device 3. The two pairs of second jaws 315 of the first U-shaped mechanism 31 and the second U-shaped mechanism 32 respectively take the wire harness from the two pairs of first jaws 2335. The structures of the first jaws 2335 and the second jaws 315 are mutually compatible, that is, the first jaws 2335 or the second jaws 315 are provided with avoidance openings to avoid each other, so that the second jaws 315 can smoothly pass from the two pairs of first jaws 2335. The first U-shaped mechanism 31 and the second U-shaped mechanism 32 receive the wire harness. Their two pairs of second grippers 315 clamp both ends of the wire harness. Then, two second rotary motors 312 drive two rotating plates 313 to rotate the two pairs of second grippers 315 by 90°, forming a U-shaped structure. Simultaneously, the first transfer unit 431 receives the clamp 200 from the feeding conveyor line 41. The pushing component 434 pushes the clamp 200 onto the second positioning seat 4325 of the second transfer unit 432. The second Z-axis drive 4323 drives the second positioning seat 4325 to rise and move directly below the locking module 5. Two third drive components 318 drive the two pairs of second grippers 315 to move along the Y-direction and approach each other. The clamp 315, holding the wire harness, enters the clearance space 204 from both sides of the clamp 200. At the same time, the clamp also enters the clearance channel 319 of the second clamp 315, so that the wire harness is locked into the groove of the clamp. Then, the locking module 5 tightens the screw 205 onto the clamp base 201, and assembles the clamp base 201 and the clamp cover 202, thereby pressing and positioning the wire harness on the clamp 200, realizing the U-shaped action of the wire harness and the locking of the screw. Then, the second Z-axis drive 4323 drives the second positioning seat 4325 to descend, and the pushing component 434 pushes the clamp 200, so that the assembled clamp 200 moves to the unloading conveyor line 42. The clamp 200, which clamps several wire harnesses, flows directly to the subsequent workstation for subsequent operations.

[0033] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
