Description

Technical Field

[0001] The invention relates to the technical field of wire harness butt joint and pressing, and in particular to a wire harness butt joint and pressing method. Background Art

[0002] The existing method for butt-jointing and pressing wire harnesses is to press them through a single-station pressing device, that is, the two sets of relative wire harnesses that need to be butt-jointed and pressed are both located in a receiving slot on a single station on the same side for subsequent paralleling, heat shrink tubing, pressing and other operations. When the size of the wire harness is long, the wire harness is prone to winding and needs to be manually separated. Some wire harnesses are even tied into knots, which are not easy to separate, are time-consuming and labor-intensive, and affect processing efficiency. Summary of the invention

[0003] The present invention aims to provide a wire harness butt-jointing and pressing method to solve the above-mentioned technical problems.

[0004] To achieve the above object, the technical solution of the present invention is: a wire harness butt-jointing and pressing method, comprising the following steps:

[0005] S1. Install the waterproof plugs and terminals to the rear ends of multiple wiring harnesses in sequence;

[0006] S2. The wire harnesses are transported backward one by one through the conveyor line. After the wire harnesses are transported to the set position, the wire cutting mechanism cuts the wire harnesses, and the first transport mechanism of the left processing position or the right processing position clamps the front end of the wire harnesses. The main body of the wire harnesses slides to the left side into the receiving trough of the left processing position or slides to the right side into the receiving trough of the right processing position according to the set requirements;

[0007] S3, the first transport mechanisms of the left and right processing positions respectively clamp the front end of the wire harness of the corresponding processing position and transport it backward to the line-joining mechanism of the corresponding processing position, and the line-joining mechanism is used to join multiple wire harnesses located at the same processing position or transfer and place a single wire harness;

[0008] S4, the second transport mechanisms of the left and right processing positions respectively clamp the front end of the wire harness at the corresponding processing position and transport it backward to the tube insertion mechanism, and the heat shrink tube is sleeved on the front end of the wire harness through the tube insertion mechanism;

[0009] S5. The third transport mechanisms of the left and right processing positions respectively clamp the front ends of the wire harnesses of the corresponding processing positions and transport them backward to the pressing mechanism, and the front ends of the wire harnesses of the two processing positions are pressed together by the pressing mechanism.

[0010] Furthermore, the method further comprises the following steps:

[0011] S6, the fourth transport mechanism clamps the pressed wire harness and transports it backward to the heat shrink mechanism, and the heat shrink mechanism shrinks the heat shrink tube on the wire harness. Then the fourth transport mechanism transports the wire harness backward to the wire collection platform for unified collection.

[0012] Furthermore, step S1 further includes the following steps:

[0013] S1.1. Multiple wire harnesses are delivered to the swing arm device in parallel through the wire feeding device. The swing arm device rotates to drive the rear ends of the multiple wire harnesses to move to the waterproof plug sleeve device. The waterproof plug sleeve device sleeves the waterproof plug to the rear ends of the corresponding wire harnesses;

[0014] S1.2. The swing arm device rotates to drive the rear ends of the plurality of wire harnesses to move to the terminal crimping device, and the terminal is crimped to the rear ends of the corresponding wire harnesses through the terminal crimping device.

[0015] Furthermore, the waterproof plug socket device includes a first conveying mechanism, a first material transfer mechanism, a first assembly mechanism, a second conveying mechanism, a second material transfer mechanism, a second assembly mechanism and a switching mechanism that cooperate with each other. There are two waterproof plug socket devices, and each waterproof plug socket device can socket two different types of waterproof plugs. The two waterproof plug socket devices can socket four different types of waterproof plugs at most; step S1.1 also includes the following steps:

[0016] S1.1.1. First, the first type of waterproof plug is sleeved. The first assembly mechanism and the first wiring harness on the swing arm device are both located at the sleeved position and arranged relatively. The first type of waterproof plug is transported by the first conveying mechanism. Then, the first type of waterproof plug on the first conveying mechanism is taken out and transferred to the first assembly mechanism by the first material taking and transferring mechanism. Then, the first type of waterproof plug is sleeved on the first wiring harness by the first assembly mechanism.

[0017] S1.1.2. Then, the second type of waterproof plug is sleeved. The swing arm device is translated to move the second wiring harness to the sleeved position. The second type of waterproof plug is transported by the second conveying mechanism. Then, the second type of waterproof plug on the second conveying mechanism is taken out and transferred to the second assembly mechanism by the second material taking and transferring mechanism. The switching mechanism drives the second assembly mechanism to translate to the sleeved position and be arranged opposite to the second wiring harness. Then, the second type of waterproof plug is sleeved onto the second wiring harness by the second assembly mechanism.

[0018] Furthermore, the waterproof plug sleeve device and the terminal crimping device are arranged on the periphery of the swing arm device, and the swing arm device includes a base, a first drive module, a second drive module, a rotating disk and a swing arm mechanism that cooperate with each other. The rotating disk is rotatably arranged on the base, and a clearance through hole is opened in the middle of the rotating disk. The first drive module is drivingly connected to the rotating disk. A plurality of wire clamps for clamping the wire harness are arranged side by side on the swing arm mechanism. A slide rail, a slider and a connecting piece are arranged on the bottom side of the swing arm mechanism. The connecting piece is fixedly connected to one side of the top of the rotating disk. The slider is slidably arranged on the slide rail. The output shaft of the second drive module passes through the clearance through hole in the upward direction and is connected to the slider.

[0019] When the first driving module is started alone, the first driving module drives the rotating disk to rotate, thereby driving the swing arm mechanism to rotate, so that the wiring harness is switched to different stations for processing;

[0020] When the first driving module and the second driving module are started at the same time, the first driving module and the second driving module cooperate with each other to drive the swing arm mechanism to translate back and forth, so that the wiring harnesses on the swing arm mechanism can be switched one by one for processing.

[0021] Furthermore, the lamination type of the wire harness is one-to-one, one-to-many, or many-to-many lamination. When the number of wire harnesses to be laminarized corresponding to the processing position is one, the paralleling mechanism of the processing position is used to transfer and place the single wire harness. When the number of wire harnesses to be laminarized corresponding to the processing position is multiple, the paralleling mechanism of the processing position is used to parallel multiple wire harnesses.

[0022] Furthermore, in step S5, the wiring harness is pressed by riveting or ultrasonic welding.

[0023] The present invention has the following beneficial effects:

[0024] The pressing method of the present invention enables two groups of relative wire harnesses that need to be pressed to be located at the processing positions on the left and right sides respectively to independently perform the wire paralleling process and the heat shrink tube application process, and then perform the pressing process. The main body of the wire harness can be laid in the receiving trough in a relatively orderly and smooth manner, so that the wire harness is longer in size and is not prone to winding and knotting, thereby avoiding subsequent manual separation operations, saving time and labor, and improving processing efficiency.

[0035] See also Figure 1-6 As shown, as an embodiment of the present invention, a wire harness butt-jointing and pressing method is provided, comprising the following steps:

[0036] S1. Install the waterproof plugs and terminals to the rear ends of multiple wiring harnesses in sequence;

[0037] S2, the wire harnesses are transported backward one by one through the conveyor line 5, and after the wire harnesses are transported to the set position, the wire cutting mechanism 6 cuts the wire harnesses, and the first conveying mechanism 8 of the left processing position 17 or the right processing position 18 clamps the front end of the wire harnesses, and the main body of the wire harnesses slides to the left side into the receiving trough 12 of the left processing position 17 or slides to the right side into the receiving trough 12 of the right processing position 18 according to the set requirements, wherein the main body of the wire harnesses refers to the part except the front end of the wire harnesses;

[0038] S3, the first transport mechanisms 8 of the left and right processing positions respectively clamp the front end of the wire harness of the corresponding processing position and transport it backward to the line-joining mechanism 7 of the corresponding processing position, and the line-joining mechanism 7 joins the multiple wire harnesses at the same processing position or transfers and places a single wire harness;

[0039] S4, the second transport mechanisms 9 of the left and right processing positions respectively clamp the front end of the wire harness at the corresponding processing position and transport it backward to the tube insertion mechanism 14, and the heat shrink tube is sleeved on the front end of the wire harness through the tube insertion mechanism 14;

[0040] S5. The third transport mechanisms 10 of the left and right processing positions respectively clamp the front ends of the wire harnesses of the corresponding processing positions and transport them backwards to the pressing mechanism 13, and the pressing mechanism 13 presses the front ends of the wire harnesses of the two processing positions together.

[0041] S6, the fourth transport mechanism 11 clamps the pressed wire harness and transports it backward to the heat shrink mechanism 15, and the heat shrink mechanism 15 shrinks the heat shrink tube on the wire harness. Then the fourth transport mechanism 11 transports the wire harness backward to the wire collection platform 16 for unified collection.

[0042] This pressing method enables two groups of relative wire harnesses that need to be pressed to be located at the processing positions on the left and right sides respectively for independent wire paralleling processing and heat shrink tube sleeve operation, and then pressing processing, and the main body of the wire harness can be laid in the receiving groove 12 in a relatively orderly and smooth manner, and even if the size of the wire harness is long, it is not easy to get tangled or knotted, thereby avoiding subsequent manual separation operations, saving time and labor, and improving processing efficiency.

[0043] Wherein, step S1 further includes the following steps:

[0044] S1.1. Multiple wire harnesses are transported to the swing arm device 3 in parallel through the wire feed device 1. The swing arm device 3 rotates to drive the rear ends of the multiple wire harnesses to move to the waterproof plug sleeve device 4. The waterproof plug sleeve device 4 sleeves the waterproof plug to the rear ends of the corresponding wire harnesses;

[0045] S1.2. The swing arm device 3 rotates to drive the rear ends of the plurality of wire harnesses to move to the terminal crimping device 2, and the terminal crimping device 2 crimps the terminal to the rear ends of the corresponding wire harnesses.

[0046] That is, the swing arm device 3 is rotated to drive the wiring harness to be switched to the waterproof plug sleeve device 4 and the terminal crimping device 2 for processing of corresponding processes, which is more convenient to operate and occupies less space.

[0047] The waterproof plug socket device 4 includes a first conveying mechanism 41, a first material transfer mechanism 42, a first assembly mechanism 43, a second conveying mechanism 44, a second material transfer mechanism 45, a second assembly mechanism 46 and a switching mechanism 47 that cooperate with each other. The switching mechanism 47 is a cylinder. There are two waterproof plug socket devices 4, and each waterproof plug socket device 4 can be socketed with two different types of waterproof plugs. The two waterproof plug socket devices 4 can be socketed with four different types of waterproof plugs at most. Step S1.1 also includes the following steps:

[0048] S1.1.1. First, the first waterproof plug is sleeved. The first assembly mechanism 43 and the first wiring harness on the swing arm device 3 are both located at the sleeved position and arranged relatively. The first waterproof plug is transported by the first conveying mechanism 41. Then, the first waterproof plug on the first conveying mechanism 41 is taken out and transferred to the first assembly mechanism 43 by the first material transfer mechanism 42. Then, the first waterproof plug is sleeved on the first wiring harness by the first assembly mechanism 43.

[0049] S1.1.2. Then, the second waterproof plug is sleeved. The swing arm device 3 is translated to move the second wiring harness to the sleeved position. The second waterproof plug is transported by the second conveying mechanism 44. Then, the second waterproof plug on the second conveying mechanism 44 is taken out and transferred to the second assembly mechanism 46 by the second material taking and switching mechanism 45. The switching mechanism 47 drives the second assembly mechanism 46 to translate to the sleeved position and be arranged opposite to the second wiring harness. Then, the second waterproof plug is sleeved on the second wiring harness by the second assembly mechanism 46.

[0050] This method enables the waterproof plug socket device 4 to automatically and quickly switch and transport two types of waterproof plugs of different specifications, and to socket them on corresponding different types of wiring harnesses. It has high versatility and high production efficiency. There is no need to disassemble and replace the waterproof plug socket device 4, saving economic costs.

[0051] Among them, the waterproof plug sleeve device 4 and the terminal crimping device 2 are arranged on the peripheral side of the swing arm device 3. The swing arm device 3 includes a base 31, a first drive module 32, a second drive module 33, a rotating disk 34 and a swing arm mechanism 35 that cooperate with each other. The rotating disk 34 is rotatably arranged on the base 31. A clearance through hole is opened in the middle of the rotating disk 34. The first drive module 32 is drivingly connected to the rotating disk 34. A plurality of wire clamps 36 for clamping the wire harness are arranged side by side on the swing arm mechanism 35. A slide rail 37, a slider 38 and a connecting member 39 are arranged on the bottom side of the swing arm mechanism 35. The connecting member 39 is fixedly connected to the top side of the rotating disk 34. The slider 38 is slidably arranged on the slide rail 37. The output shaft of the second drive module 33 passes through the clearance through hole and is connected to the slider 38.

[0052] When the first driving module 32 is started alone, the first driving module 32 drives the rotating disk 34 to rotate, thereby driving the swing arm mechanism 35 to rotate, so that the wire harness is switched to different workstations for processing;

[0053] When the first driving module 32 and the second driving module 33 are started at the same time, the first driving module 32 and the second driving module 33 cooperate with each other to drive the swing arm mechanism 35 to move back and forth, so that the wire harnesses on the swing arm mechanism 35 can be switched one by one for processing. Among them, the first driving module 32 and the second driving module 33 are motor structures.

[0054] This arrangement enables the wiring harness to be quickly switched to different processing devices for processing in different processes through the mutual cooperation among the first drive module 32, the second drive module 33, the rotating disk 34 and the swing arm mechanism 35. On the other hand, it enables multiple wiring harnesses to be quickly switched on the same processing device to achieve the processing of the same process, thereby improving the processing efficiency, and the overall structural layout is more reasonable and compact, occupying less space.

[0055] Among them, the lamination type of the wire harness is one-to-one, one-to-many, or many-to-many lamination. When the number of wire harnesses pressed corresponding to the processing position is one, the paralleling mechanism 7 of the processing position is used to transfer and place a single wire harness. When the number of wire harnesses pressed corresponding to the processing position is multiple, the paralleling mechanism 7 of the processing position is used to parallel multiple wire harnesses.

[0056] Among them, each transport mechanism in this embodiment is a transport clamping claw structure.

[0057] In step S5, the wiring harness is pressed by riveting or ultrasonic welding.

[0058] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims will fall within the scope of protection of the present invention.
