Abstract

This invention relates to the field of wire harness paralleling and crimping equipment, specifically to a wire harness paralleling and crimping device. A multi-line, multi-station processing unit simultaneously processes multiple coils of wire into connecting wires, adapting to the processing of connecting wires with at least one type of the same or different terminals. It allows for flexible and compatible combinations and improves processing efficiency. Multiple connecting wires are transferred and paralleled by a paralleling mechanism, then through a heat-shrink tubing insertion mechanism, a twisting mechanism, and a crimping machine that crimps the rear leads of two sets of parallel connecting wires together to form a single unit. A heat-shrinking mechanism then heat-shrinks and fixes the heat-shrink tubing. Finally, a robotic arm clamps the wire harness for unloading. This method avoids the need for manual assembly of terminal connecting wires to produce one-to-one, one-to-many, or many-to-many wire harnesses, reducing errors during paralleling, incomplete or missed heat-shrink tubing insertion, and improving processing efficiency, saving labor, and reducing processing costs.

Description

Technical Field

[0001] This invention relates to the field of wire harness paralleling and pressing equipment, and more specifically to a wire harness paralleling and pressing equipment. Background Technology

[0002] Terminal connectors, also known as terminal wires or connector terminals, are a type of connector wire widely used in electronic devices. They are wires with connectors and typically consist of two parts: a connector housing and a wire with terminals.

[0003] For wire harnesses composed of multiple terminal connecting wires in one-to-one, one-to-many, or many-to-many configurations, the process typically involves manual stripping of the front end of the connecting wires, terminal crimping, cutting into single connecting wires, and stripping of the rear end, using a processing unit or an automated processing unit. Then, the multiple connecting wires are manually connected together according to actual needs, and heat shrink tubing is inserted. The rear wires of two pairs of connected wires are then connected together by terminal crimping to form a one-to-one, one-to-many, or many-to-many wire harness. Finally, the heat shrink tubing is manually straightened to cover the terminals in the middle of the wire harness, and a heat shrink machine is used to shrink and fix the heat shrink tubing. This method has problems such as easy errors in the wire connection process, incomplete or missing heat shrink tubing, high processing costs, low processing efficiency, and high labor intensity, which is not conducive to saving manpower.

[0015] The beneficial effects of the present invention are as follows: The wire harness paralleling and pressing equipment of the present invention adopts a machine base, and a multi-wire multi-station processing unit, a paralleling mechanism, a heat shrink tubing insertion mechanism, a twisting mechanism, a wire-connecting and pressing machine, a heat shrinking mechanism, and a belt conveyor, all connected to the machine base and arranged sequentially along the wire harness processing direction. The machine base is also connected to a wire gathering and transferring mechanism, a first wire transferring mechanism, a second wire transferring mechanism, and a material unloading robot mechanism. The wire gathering and transferring mechanism is used to transfer the connecting wires of the multi-wire multi-station processing unit to the paralleling mechanism.

The wire gathering and transferring mechanism then transfers multiple connecting wires to the paralleling mechanism for paralleling according to the required number of wires. The first wire transferring mechanism then transfers the paralleled connecting wires to the heat-shrink tubing insertion mechanism to insert heat-shrink tubing into one group of parallel connecting wires. Finally, the paralleled connecting wires are transferred to the twisting mechanism to complete the paralleling of the two groups. The rear conductors of the connecting wires are twisted separately to connect the rear conductors of the single-set parallel connecting wires together. Then, a second wire-moving mechanism transfers and rotates the two sets of parallel connecting wires to contact each other.

This avoids the need for manual assembly of terminal connecting wires to produce one-to-one, one-to-many, or many-to-many wire harnesses, reduces errors during the paralleling process, and minimizes the chance of missing or incorrect heat-shrink tubing. It also improves processing efficiency, saves labor, and reduces processing costs. Attached Figure Description

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0019] like Figure 1-10 As shown, a wire harness paralleling and pressing device includes a machine base 1, and a multi-wire multi-station processing unit 3, a paralleling mechanism 4, a heat shrink tubing insertion mechanism 5, a twisting mechanism 6, a wire pressing and pressing machine 7, a heat shrinking mechanism 8, and a belt conveyor 2, all connected to the machine base 1 and arranged sequentially along the wire harness processing direction. The machine base 1 is also connected to a wire gathering and transferring mechanism 9, a first wire transferring mechanism 10, a second wire transferring mechanism 11, and a material unloading robot mechanism 12. The wire gathering and transferring mechanism 9 is used to transfer the connecting wires of the multi-wire multi-station processing unit 3 to the paralleling mechanism 4. The first wire transferring mechanism 10 is used to transfer the parallel connecting wires of the paralleling mechanism 4 to the heat shrink tubing insertion mechanism 5 and the twisting mechanism 6. The second wire transferring mechanism 11 is used to transfer the parallel connecting wires of the first wire transferring mechanism 10 to the wire pressing and pressing machine 7 and the heat shrinking mechanism 8. The material unloading robot mechanism 12 is used to transfer the wire harnesses of the heat shrinking mechanism 8 into the heat shrinking mechanism 8 and the belt conveyor 2.

[0020] In use, the multi-line, multi-station processing unit 3 simultaneously processes multiple coils of wire by stripping the front end, terminalizing the front end, cutting them into single connecting wires, and stripping the rear end. It is compatible with at least one type of connecting wire with the same or different terminal types, allowing for flexible and compatible combinations, and improving processing efficiency. Then, the wire gathering and transferring mechanism 9 transfers multiple connecting wires to the paralleling mechanism 4 for paralleling according to the actual required number. Then, the first wire transferring mechanism 10 transfers the parallel connecting wires to the heat shrink tubing insertion mechanism 5 to insert heat shrink tubing into one group of parallel connecting wires, and then transfers the parallel connecting wires to the twisting mechanism 6 to twist the two groups of parallel connecting wires. The rear-end wires of the wiring are twisted separately to connect the rear-end wires of the single-group parallel connection wires together; then, the second wire-moving mechanism 11 transfers and rotates to bring the rear-end wires of the two groups of parallel connection wires into contact, and the wire-fitting and pressing machine 7 presses the rear-end wires of the two groups of parallel connection wires together to form a one-to-one, one-to-many, or many-to-many wire harness; then, the second wire-moving mechanism 11, in conjunction with the heat-shrinking mechanism 8, moves the heat-shrink tubing to cover the terminal in the middle of the wire harness, and the heat-shrinking mechanism 8 heat-shrinks and fixes the heat-shrink tubing; the unloading robot mechanism 12 clamps the wire harness to the belt conveyor 2 to complete the unloading. This avoids the need for manual assembly of terminal connection wires to produce one-to-one, one-to-many, or many-to-many wire harnesses, reduces problems such as errors in the paralleling process and missing or incomplete heat-shrink tubing, and helps to improve processing efficiency, save labor, and reduce processing costs.

[0021] like Figure 1 and 3As shown, the paralleling mechanism 4 further includes a paralleling bracket 41 connected to the machine base 1, an auxiliary paralleling group 42 connected to the top of the paralleling bracket 41, and a first main paralleling group 43 and a second main paralleling group 44 connected to one side of the paralleling bracket 41 and distributed adjacent to each other. The auxiliary paralleling group 42 is used to transfer the connecting line of the second main paralleling group 44 to be paralleled with the connecting line of the first main paralleling group 43.

[0022] Furthermore, the first main parallel line group 43 includes a first gripper cylinder 431 fixedly connected to the parallel line bracket 41, a first push cylinder 432 fixedly connected to the parallel line bracket 41, and a second gripper cylinder 433 fixedly connected to the output end of the first push cylinder 432 and slidably engaged with the parallel line bracket 41. When the first main parallel line group 43 is paralleled, the first gripper cylinder 431 and the second gripper cylinder 433 abut against each other. The second main parallel line group 44 includes a third gripper cylinder 44 fixedly connected to the parallel line bracket 41. 1. A second push cylinder 442 fixedly connected to the paralleling bracket 41, and a fourth gripper cylinder 443 fixedly connected to the output end of the second push cylinder 442 and slidably engaged with the paralleling bracket 41. When the second main paralleling group 44 is paralleled, the third gripper cylinder 441 and the fourth gripper cylinder 443 abut against each other. The auxiliary paralleling group 42 includes an XZ-axis linear module 421 fixedly connected to the top of the paralleling bracket 41, and an auxiliary gripper cylinder 422 fixedly connected to the output end of the XZ-axis linear module 421. In use, the first push cylinder 432 can push the second gripper cylinder 433 against the first gripper cylinder 431 so that the first group of connecting lines can be paralleled; the second push cylinder 442 can push the fourth gripper cylinder 443 against the third gripper cylinder 441 so that the second group of connecting lines can be paralleled; the XZ axis linear module 421 drives the auxiliary gripper cylinder 422 to move in the XZ axis, and the auxiliary gripper cylinder 422 clamps the second group of parallel connecting lines and moves it to be paralleled with the connecting lines of the first main parallel group 43. Compared with the traditional paralleling mechanism 4, the paralleling mechanism 4 of the present invention is more conducive to saving space and more conducive to flexible paralleling. The configuration can also be flexibly adjusted according to actual needs. For example, only the first gripper cylinder 431 and the third gripper cylinder 441 can clamp the connecting wire; or only the first gripper cylinder 431, the second gripper cylinder 433, and the third gripper cylinder 441 can clamp the connecting wire; or only the first gripper cylinder 431, the third gripper cylinder 441, and the fourth gripper cylinder 443 can clamp the connecting wire; or the second group of parallel connecting wires can be moved to be paralleled with the connecting wires of the first main parallel group 43, and then the wire transfer mechanism 9 can transfer multiple connecting wires to the parallel mechanism 4 so that the third gripper cylinder 441 and the fourth gripper cylinder 443 can clamp the connecting wires again for paralleling. This allows for the subsequent formation of one pair of wire harnesses, one pair of multiple wire harnesses, or multiple pairs of multiple wire harnesses.

[0023] like Figure 1 , 4 As shown in Figure 5, the heat shrink tubing threading mechanism 5 further includes a heat shrink tubing unwinding machine 51 fixedly connected to the machine base 1, a tubing threading bracket 55 fixedly connected to the machine base 1, a YZ axial linear module 52 fixedly connected to the top of the tubing threading bracket 55, a heat shrink tubing clamping cylinder 53 fixedly connected to the output end of the YZ axial linear module 52, a first cylinder clamping assembly 54 fixedly connected to the machine base 1 and connected to the first wire transfer mechanism 10, and a straightener 56, a bladed finger slide table 57, and a heat shrink tubing recycling tank 58, all fixedly connected to one side of the tubing threading bracket 55 and arranged sequentially along the heat shrink tubing conveying direction; the first wire transfer mechanism 10 includes a first X-direction linear module 101 fixedly connected to the machine base 1, a first wire transfer seat 102 fixedly connected to the output end of the first X-direction linear module 101, and a first wire transfer gripper cylinder 103 fixedly connected to the top of the first wire transfer seat 102. The heat shrink tubing is unwound by the heat shrink tubing unwinder 51, straightened by the straightener 56, and then passed through. The heat shrink tubing clamping cylinder 53 moves along the YZ axis driven by the YZ axis linear module 52. The heat shrink tubing clamping cylinder 53 clamps the heat shrink tubing and pulls it out. Then, the heat shrink tubing is cut by the knife-wielding finger slide 57. The heat shrink tubing clamping cylinder 53 then places the heat shrink tubing into one of the sets of parallel connecting lines. The heat shrink tubing recycling tank 58 facilitates the recycling of the heat shrink tubing that has been cut off by the heat shrink tubing clamping cylinder 53 when the machine stops.

When the rear conductors of the two sets of parallel connecting wires need to be joined, two first double-duty displacement line clamping cylinders 115 respectively clamp the two sets of parallel connecting wires. Two first double-duty rotary cylinders 114 drive the first double-duty displacement line clamping cylinders 115 to rotate the parallel connecting wires so that the rear conductors of the two sets of parallel connecting wires are joined so that the wire bonding press 7 can be crimped to form an integral wire harness. Then, three second double-duty displacement line clamping cylinders 117 clamp the wire harness and transfer it to the heat shrinking mechanism 8.

[0026] like Figure 1 and 7 As shown, the wire-connecting press 7 further includes a terminal press and two pressing manipulators 71 distributed on both sides of the terminal press and connected to the first double-acting displacement wire clamping cylinder 115. The two pressing manipulators 71 are used to clamp the two ends of the wire-connecting wire, and the terminal press is used to press the middle of the wire-connecting wire into a terminal. In use, after the rear wires of the two sets of parallel wire-connecting wires are joined together, the two pressing manipulators 71 clamp the two ends of the wire-connecting wire to complete the handover, so that the terminal press can press the terminals to form an integral wire harness.

[0027] like Figure 1 and 2As shown, the multi-line, multi-station processing unit 3 further includes multiple sets of spaced-apart translational wire feeding mechanisms 31, front stripping and cutting mechanisms 32, terminal crimping machines 33, and rear stripping mechanisms 34 arranged sequentially along the conveying direction of the connecting wires; the wire gathering and shifting mechanism 9 includes a second X-direction linear module 91, a second wire shifting base 92 fixedly connected to the output end of the second X-direction linear module 91, and four spaced-apart second wire shifting gripper cylinders 93 fixedly connected to the top of the second wire shifting base 92. The second wire shifting gripper cylinders 93 are used to clamp the connecting wires output by the rear stripping mechanism 34. Multiple sets of processing mechanisms composed of translational wire feeding mechanisms 31, front stripping and cutting mechanisms 32, terminal crimping machines 33, and rear stripping mechanisms 34 are adapted to process connecting wires of at least one type of the same / different terminals, allowing for flexible and compatible combinations, and improving processing efficiency. The wire gathering and shifting mechanism 9 uses four second wire shifting gripper cylinders 93 to simultaneously clamp and transfer four connecting wires, resulting in higher efficiency. In this embodiment, the multi-line multi-station processing unit 3 includes three sets of spaced-apart translational feeding mechanism 31, front peeling and cutting mechanism 32, terminal crimping machine 33 and rear peeling mechanism 34 arranged sequentially along the conveying direction of the connecting line.

[0028] like Figure 1 and 9 As shown, the heat shrinking mechanism 8 further includes a heat shrinking base 81 fixedly connected to the machine base 1, a Y-axis pushing cylinder 82 fixedly connected to the heat shrinking base 81, a heat shrinking cylinder seat 83 fixedly connected to the output end of the Y-axis pushing cylinder 82 and slidably disposed on the heat shrinking base 81, two fifth gripper cylinders 84 fixedly connected to the heat shrinking cylinder seat 83 and engaged with the second wire transfer mechanism 11, a tube-strapping gripper cylinder 85 fixedly connected to the heat shrinking cylinder seat 83 and located between the two fifth gripper cylinders 84, a heat collection tank 86 fixedly connected to the heat shrinking base 81, a sixth gripper cylinder 87 fixedly connected to both sides of the heat collection tank 86, and a fixedly connected... The heat shrink bracket 81 includes a first cooling fan 88, a seventh gripper cylinder 89 fixedly connected to both sides of the first cooling fan 88, a second cooling fan 810 fixedly connected to the end of the heat shrink bracket 81 and close to the first cooling fan 88, a heat shrink bracket 811 fixedly connected to the machine base 1, a Z-direction drive cylinder 812 fixedly connected to the heat shrink bracket 811, and a hot air gun 813 fixedly connected to the output end of the Z-direction drive cylinder 812. The air outlet of the hot air gun 813 faces the heat collection tank 86. The heat shrink cylinder base 83, the heat collection tank 86, the first cooling fan 88 and the second cooling fan 810 are arranged sequentially along the wire harness processing direction.

[0029] like Figure 1 and 10As shown, the unloading robot mechanism 12 further includes an unloading bracket 121 fixedly connected to the machine base 1, a Y-axis linear module 122 fixedly connected to one side of the unloading bracket 121, an unloading support 123 fixedly connected to the output end of the Y-axis linear module 122, and a first pair of gripper cylinders 124, a second pair of gripper cylinders 125, and a third pair of gripper cylinders 126, all fixedly connected to the unloading support 123 and spaced apart. The unloading support 123 is fixedly connected to a third cooling fan 127 located between the third pair of gripper cylinders 126. The first pair of gripper cylinders 124 is used to transfer the wiring harness of the fifth gripper cylinder 84 to the sixth gripper cylinder 87, the second pair of gripper cylinders 125 is used to transfer the wiring harness of the sixth gripper cylinder 87 to the seventh gripper cylinder 89, and the third pair of gripper cylinders 126 is used to transfer the wiring harness of the seventh gripper cylinder 89 to the belt conveyor 2.

[0030] When the wire harness needs heat shrinking, the second wire-moving clamp cylinder 93 and the tube-straightening clamp cylinder 85 work together to move the heat shrink tubing to cover the terminal in the middle of the wire harness. The Y-axis pushing cylinder 82 drives the heat shrink cylinder seat 83, which in turn drives the fifth clamp cylinder 84, the tube-straightening clamp cylinder 85, and the wire harness to move closer to the heat collection tank 86. Then, the first pair of clamp cylinders 124 transfers the wire harness from the fifth clamp cylinder 84 to the sixth clamp cylinder 87. The Z-axis driving cylinder 812 drives the hot air gun 813 to descend and approach the heat shrink tubing, and the hot air... Gun 813 heats the heat shrink tubing to shrink it and then resets it. Then, the second pair of gripper cylinders 125 transfers the wire harness from the sixth gripper cylinder 87 to the seventh gripper cylinder 89. The first cooling fan 88 and the second cooling fan 810 work together to quickly cool down the wire harness. Then, the third pair of gripper cylinders 126 transfers the wire harness from the seventh gripper cylinder 89 to the belt conveyor 2. At the same time, the third cooling fan 127 further cools down the wire harness to prevent the residual heat of the heat shrink tubing from sticking to foreign objects or sticking to / deforming the belt conveyor 2.

[0031] It should be noted that in this embodiment, the translational wire feeding mechanism 31, the front stripping and cutting mechanism 32, the terminal crimping machine 33, the rear stripping mechanism 34, the terminal pressing machine, and the belt conveyor 2 are all existing technologies, and will not be described in detail here.

[0032] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present invention are within the protection scope of the present invention.
