Description

Technical Field

[0001] The present invention relates to the technical field of wire harness production, and in particular to a wire harness production process, equipment and a bending-resistant wire harness assembly. Background Art

[0002] Wire harness production is the process of processing and assembling components such as wires, cables, and connectors to make wire harness products. There is a step in the wire harness production process that requires winding multiple strands of wire harnesses together, which is called wire harness twisting, which directly affects subsequent steps such as terminal crimping.

[0003] In the prior art, when twisting wire harnesses, multiple strands of wire harnesses need to be wrapped into a group using tape. The wire harnesses are not limited before being wrapped, so it is very easy for them to be entangled with each other before the tape is wrapped. Once this happens, when the tape is wrapped again, it is easy for the harness to break due to the stress of the tape wrapping. Summary of the Invention

Simultaneously, the tape revolves around the multi-strand harness, twisting the harness into one strand through the tape, and winding the harness into one strand.

The squeezing force makes the tape fit tightly against the multi-strand wire harness, preventing the tape from being loosely twisted due to the stress of the tape when the tape is wrapped around the multi-strand wire harness.

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] Reference Figures 1-8 The present invention provides a technical solution: a wire harness production process, comprising the following steps: S1: Pull out a section of tape and manually wrap the tape around the initial end of the multi-strand wire harness, install and position the tape, clamp and position the wrapped wire harness so that the wrapped wire harness can only move in the horizontal direction, and laterally restrain the multi-strand unwound wire harness so that the vertical movement of the multi-strand unwound wire harness is restricted; S2: Adaptively clamping the tape-wound multi-strand harness according to its initial size, pulling the tape-wound harness into one strand through rolling friction at the clamping end, and then driving the unwound multi-strand harness to move. Simultaneously, the tape revolves around the multi-strand harness, twisting the harness into one strand through the tape, and winding the harness into one strand. S3: When the wound wire harness is pulled and moved, the tape wrapped around the multi-strand wire harness is squeezed by elastic clamping. The squeezing force makes the tape and the multi-strand wire harness fit tightly together, preventing the tape from being loosely twisted due to the stress of the tape when the tape is wrapped around the multi-strand wire harness. Reference Figures 1-8, a wire harness production equipment, suitable for a wire harness production process, including a base 1, a wire management mechanism is provided on the top of the base 1, the wire management mechanism includes a first support frame 201, the first support frame 201 is fixedly installed on the top of the base 1, and two first fixed plates 202 are fixedly installed on the top of the first support frame 201, and the interiors of the two first fixed plates 202 are both slidably sleeved with first slide bars 203, and the opposite sides of the two first slide bars 203 are fixedly installed with wire management plates 204, and the two wire management plates 204 are mirror-imaged along the central axis of the first support frame 201, and a plurality of elastic ridges 205 are provided on the wire management plates 204, and the elastic ridges 205 are made of rubber. A first spring 206 is installed between the fixing plates 202. By setting up a wire management mechanism, the user inserts the multi-strand wire harness that has not been wrapped with tape into the two wire management plates 204 from top to bottom. Due to the wedge-shaped setting of the top of the wire management plate 204, the wire harness can smoothly enter the position between the two wire management plates 204, and the resilience of the first spring 206 limits the position of the wire harness. After the wire harness is inserted between the connected elastic protrusions 205, the friction force of the elastic protrusions 205 prevents the wire harness from moving in the vertical direction after being pulled, thereby preventing the multi-strand wire harness from being entangled with each other when the tape is about to be wrapped, thereby improving the accuracy of the wire harness twisting. Reference Figures 1-8The top of the first support frame 201 is fixedly installed with a first wiring line 207, and the first wiring line 207 is located on the center line of the first support frame 201. The top of the first support frame 201 is provided with two slide grooves 208. The inner sliding sleeve of the slide groove 208 is provided with a second wiring line 209 and a third wiring line 210. The second wiring line 209 and the wiring plate 204 are fixedly connected by a connecting shaft. The bottom of the second wiring line 209 is integrally formed with two connecting strips 211. A connecting rod 212 is fixedly installed between the two connecting strips 211. The surface of the connecting rod 212 is provided with a driving gear. 213, a first tooth plate 214 is fixedly installed inside the first support frame 201, and a second tooth plate 215 is fixedly installed at the bottom of the third line 210. A limit block is installed on the second tooth plate 215, and a limit groove adapted to the limit block is opened inside the slide 208. The limit groove limits the limit block to only allow horizontal movement while limiting the movement stroke of the second tooth plate 215. The second tooth plate 215 and the first tooth plate 214 are both engaged with the driving gear 213. The second tooth plate 215 and the first tooth plate 214 are respectively located at the top and bottom of the driving gear 213. By setting the first tooth plate 2 14. The second tooth plate 215 and the driving gear 213. When the user inserts the wire harness between the two wire management plates 204, the wire management plate 204 is squeezed by the wire harness and drives the second wire management line 209 to move through the connecting shaft. The connecting bar 211 and the connecting rod 212 cooperate to drive the driving gear 213 to move away from the first wire management line 207. The meshing connection between the driving gear 213, the first tooth plate 214 and the second tooth plate 215 causes the second tooth plate 215 to drive the third wire management line 210 to move at the same time, thereby moving the first wire management line 207 and the second wire management line 207. The gaps between the wiring strips 209 and the gaps between the second wiring strip 209 and the third wiring strip 210 are synchronously enlarged, so that when facing wire harnesses of different sizes, the gaps between the first wiring strip 207 and the second wiring strip 209 and the gaps between the second wiring strip 209 and the third wiring strip 210 can be changed synchronously, thereby avoiding the situation where the gaps between the first wiring strip 207 and the second wiring strip 209 and the gaps between the second wiring strip 209 and the third wiring strip 210 become too small or too large after the size of the wire harness changes, thereby having a wide range of adaptability and a high degree of automation. Reference Figures 1-8The top of the base 1 is provided with a winding mechanism, which includes a support base 301, which is fixedly mounted on the top of the base 1, and a through hole 302 that passes through the left and right sides of the support base 301 is provided. A winding ring 303 is rotatably mounted on the left side of the support base 301, and a plurality of fixed pulleys are rotatably mounted on the left side of the support base 301, which are used to limit the rotation trajectory of the winding ring 303. By providing a transmission belt between the output shaft of the first motor and one of the fixed pulleys through a rotating pulley sleeve, the first motor can be started to drive the fixed pulley to rotate, and further drive the winding ring 303 to drive the tape to rotate. The gap between the two wire arranging plates 204 coincides with the center of the winding ring 303, and a tape positioning rod 304 is installed on the left side of the winding ring 303, and the left side of the tape positioning rod 304 is installed by bolts There is a tape positioning plate 305. By setting a winding mechanism, the user pulls out a section of the tape, puts the tape on the tape positioning rod 304, and fixes the tape positioning plate 305 with bolts. After manually winding the redundant tape onto the multi-strand wire harness, the wire harness wound into one strand is clamped on the two clamping plates 309, and the unwound multi-strand wire harness is placed between the first wiring harness 207, the second wiring harness 209 and the third wiring harness 210. Then, the first motor is started, and through the cooperation of the rotating wheel and the transmission belt, one of the fixed pulleys is driven to rotate, and then the winding ring 303 is driven to rotate, so that the tape begins to be wound around the multi-strand wire harness. At this time, the wound wire harness is pulled, so that the wire harness can be automatically wound with tape without excessive human intervention. Reference Figures 1-8 The top of the base 1 is fixedly installed with a second support frame 306, and the top of the second support frame 306 is fixedly installed with two second fixing plates 307. The interior of the two second fixing plates 307 is slidably sleeved with a second slide bar 308, and the opposite side of the two second slide bars 308 is fixedly installed with a clamping plate 309. A second spring 310 is installed between the clamping plate 309 and the second fixing plate 307. By setting the clamping plate 309, due to the wedge shape of the top of the clamping plate 309, the user can easily clip the wire harness wrapped with the tape between the two clamping plates 309 from top to bottom. The rebound force of the two second springs 310 makes the clamping plate 309 clamp the wire harness. When the wire harness is pulled and moved, the wrapped tape fits more tightly with the wire harness. Reference Figures 1-8The support seat 301 is provided with an adjustment mechanism, which includes a first guide roller 401 and a second guide roller 402. The first guide roller 401 and the second guide roller 402 are arranged on the inner wall of the support seat 301. The support seat 301 is provided with a first adjustment groove 403 and a second adjustment groove 404 which pass through the support seat 301. The interior of the first adjustment groove 403 and the interior of the second adjustment groove 404 are both slidably provided with a first adjustment block 405 and a second adjustment block 406. The first guide roller 401 and the second guide roller 402 are rotatably installed between the two first adjustment blocks 405 and between the two second adjustment blocks 406 respectively. The first adjustment groove 40 3 is fixedly installed inside, and the front first adjustment block 405 and the front second adjustment block 406 are slidably sleeved on the surface of the limit bar. By setting the adjustment mechanism, when the front first adjustment block 405 and the second adjustment block 406 move in opposite directions, the distance between the first guide roller 401 and the second guide roller 402 becomes larger, and conversely, the distance between the first guide roller 401 and the second guide roller 402 becomes smaller, so that the distance between the first guide roller 401 and the second guide roller 402 can be adjusted according to the size of the wire harness. When dealing with wire harnesses of different sizes, there is no need to replace equipment, which greatly saves costs; Reference Figures 1-8, a bidirectional screw rod 407 is rotatably installed between the support seat 301 and the base 1, and the front first adjusting block 405 and the second adjusting block 406 are respectively threadedly sleeved on the two ends of the bidirectional screw rod 407, and the rear first adjusting block 405 is rotatably installed with a first bevel gear 408 and a second bevel gear 409. The internal fixed sleeve of the first bevel gear 408 is provided with a connecting rod, and the connecting rod is fixedly connected to the first guide roller 401, and the first bevel gear 408 and the second bevel gear 409 are meshed. A spline sleeve 410 is fixedly installed inside the second bevel gear 409, and a spline shaft 411 is rotatably installed on the inner top wall of the support seat 301, and the spline sleeve 410 is slidably sleeved on the surface of the spline shaft 411. The second motor and the third motor are installed on the top of the support seat 301, and the output end of the second motor is connected to the top of the bidirectional screw rod 407, and the output end of the third motor is connected to the top of the spline shaft 411. By setting the spline shaft 411 and the spline sleeve 410, When the second motor is started, it drives the bidirectional screw rod 407 to rotate. Since the first adjusting block 405 and the second adjusting block 406 on the front side are both threadedly connected to the bidirectional screw rod 407, and the thread directions at both ends of the bidirectional screw rod 407 are opposite, the first adjusting block 405 and the second adjusting block 406 can move in opposite directions or opposite directions at the same time. When the distance between the front first adjusting block 405 and the front second adjusting block 406 changes, the distance between the rear first adjusting block 405 and the second adjusting block 406 changes at the same time, thereby driving the spline sleeve 410 to move upward or downward, so that it does not affect the start of the third motor to drive the spline shaft 411 and the spline sleeve 410 to rotate. The spline sleeve 410 can slide on the surface of the spline shaft 411, and the meshing connection of the first bevel gear 408 and the second bevel gear 409 causes the first guide roller 401 to rotate, thereby pulling the wiring harness; A bending-resistant wire harness component is suitable for a wire harness production device. The bending-resistant wire harness component is used on the wire harness production device.

[0023] Specifically, the working process or working principle of the wire harness production process, equipment and bending-resistant wire harness assembly is as follows: when in use, pull out a section of the tape and manually wrap the tape around the initial end of the multi-strand wire harness, install the tape on the tape positioning rod 304, install the tape positioning plate 305 on the tape positioning rod 304 by bolts, position the tape, and the user starts the second motor to drive the front first adjustment block 405 and the front second adjustment block 406 to move in opposite directions at the same time until the wrapped wire harness can be The first guide roller 401 and the second guide roller 402 are inserted into the gap between the first guide roller 401 and the second guide roller 402, and the contact with the two is maintained. The wound wire harness is clamped between the two clamping plates 309 from top to bottom, and the multiple strands of wire harness that are not wrapped with tape are clamped between the two wire management plates 204. After the wire management plate 204 is squeezed by the wire harness, the second wire management line 209 is driven to move through the connecting shaft, and the driving gear 213 is driven to move away from the first wire management line 207 through the cooperation of the connecting strip 211 and the connecting rod 212. The meshing connection between the gear 213 and the first tooth plate 214 and the second tooth plate 215 causes the second tooth plate 215 to drive the third wiring line 210 to move simultaneously, thereby causing the gap between the first wiring line 207 and the second wiring line 209 and the gap between the second wiring line 209 and the third wiring line 210 to be synchronously enlarged, and multiple strands of wire harnesses that are not wrapped with tape are passed through the gaps between the first wiring line 207, the second wiring line 209 and the third wiring line 210, and the first motor is started, and the gear 213 is driven by the cooperation of the wheel and the transmission belt. , driving one of the fixed pulleys to rotate, and then driving the winding ring 303 to rotate, so that the tape begins to wrap around the multiple wire harnesses, and at the same time starting the third motor to drive the spline shaft 411 to rotate, and through the meshing connection between the spline shaft 411 teeth and the spline sleeve 410 teeth, the spline sleeve 410 drives the second bevel gear 409 to rotate, and through the meshing connection between the second bevel gear 409 and the first bevel gear 408, the first bevel gear 408 drives the first guide roller 401 to rotate through the connecting rod, thereby pulling the wire harness.
