Description

Technical Field

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

[0002] The existing wire harness butt pressing method uses a single-station pressing device. This means that the two sets of opposing wire harnesses to be butt pressed are located in the receiving trough on the same side of the single station, followed by subsequent operations such as wire merging, heat shrink tubing, and pressing. When the wire harness is long, it is easy for the wire harness to become tangled, requiring manual separation. Some wire harnesses also have knots that are difficult to separate, which is time-consuming, labor-intensive, and affects processing efficiency. Summary of the Invention

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

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

[0005] S1. Install the waterproof plugs and terminals sequentially to the rear ends of multiple wire harnesses;

[0006] S2. The wire harness is conveyed backward one by one by the conveyor line. After the wire harness is conveyed to the set position, the wire cutting mechanism cuts the wire harness. The first conveying mechanism of the left processing position or the right processing position clamps the front end of the wire harness. The main body of the wire harness slides to the left side into the receiving trough of the left processing position or to the right side into the receiving trough of the right processing position according to the set requirements.

[0007] S3. The first conveying mechanism of the left and right processing positions respectively clamps the front end of the wire harness of the corresponding processing position and moves it to the paralleling mechanism of the corresponding processing position. The paralleling mechanism can be used to parallel multiple wire harnesses located in the same processing position or to transfer and place a single wire harness.

[0008] S4. The second conveying mechanisms of the left and right processing positions respectively clamp the front end of the wire harness at the corresponding processing position and convey it to the tube threading mechanism. The heat shrink tubing is then placed on the front end of the wire harness through the tube threading mechanism.

[0009] S5. The third conveying mechanism of the left and right processing positions respectively clamps the front end of the wire harness of the corresponding processing position and moves it to the pressing mechanism. The pressing mechanism presses the front ends of the wire harness of the two corresponding processing positions together.

[0010] Furthermore, it also includes the following steps:

[0011] S6. The fourth transport mechanism clamps the pressed wire harness and transports it backward to the heat shrinking mechanism. The heat shrinking mechanism heats the heat shrink tubing on the wire harness. Then, the fourth transport mechanism transports the wire harness backward to the take-up platform for unified collection.

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

[0013] S1.1. Multiple wire harnesses are fed side by side to the swing arm device through the infeed device. The swing arm device rotates to move the rear ends of the multiple wire harnesses to the waterproof plug fitting device. The waterproof plug fitting device then fits the waterproof plug onto the rear end of the corresponding wire harness.

[0014] S1.2 The swing arm device rotates to move the rear ends of multiple wire harnesses to the terminal crimping device, and the terminal crimping device crimps the terminals to the rear ends of the corresponding wire harnesses.

[0015] Furthermore, the waterproof plug fitting device includes a first conveying mechanism, a first material handling and transfer mechanism, a first assembly mechanism, a second conveying mechanism, a second material handling and transfer mechanism, a second assembly mechanism, and a switching mechanism that cooperate with each other. There are two waterproof plug fitting devices, and each waterproof plug fitting device can fit two different types of waterproof plugs. The two waterproof plug fitting devices can fit up to four different types of waterproof plugs. Step S1.1 also includes the following steps:

[0016] S1.1.1 First, the first type of waterproof plug is connected. The first assembly mechanism and the first wire harness on the swing arm device are both located in the connection position and are set opposite to each other. The first type of waterproof plug is transported by the first conveying mechanism. Then, the first type of waterproof plug is taken out from the first conveying mechanism and transferred to the first assembly mechanism by the first material transfer mechanism. Then, the first type of waterproof plug is connected to the first wire harness by the first assembly mechanism.

[0017] S1.1.2 Then, the second type of waterproof plug is connected. The swing arm device moves horizontally so that the second wire harness moves to the connection position. The second type of waterproof plug is transported through the second conveying mechanism. Then, the second type of waterproof plug is taken out from the second conveying mechanism and transferred to the second assembly mechanism through the second material transfer mechanism. The switching mechanism drives the second assembly mechanism to move horizontally to the connection position and set opposite to the second wire harness. Then, the second type of waterproof plug is connected to the second wire harness through the second assembly mechanism.

[0018] Furthermore, the waterproof plug fitting device and the terminal crimping device are arranged on the periphery of the swing arm device. 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 mounted on the base. A clearance through hole is opened in the middle of the rotating disk. The first drive module is driven and connected to the rotating disk. Multiple wire clamps for clamping wire harnesses are arranged side by side on the swing arm mechanism. A slide rail, a slider and a connector are arranged on the bottom side of the swing arm mechanism. The connector is fixedly connected to the top side of the rotating disk. The slider is slidably mounted on the slide rail. The output axis of the second drive module passes through the clearance through hole and is connected to the slider.

[0019] When the first drive module is started independently, it drives the rotary table to rotate, which in turn drives the swing arm mechanism to rotate, thereby allowing the wire harness to switch to different workstations for processing.

[0020] When the first drive module and the second drive module start simultaneously, they cooperate to drive the swing arm mechanism to move back and forth, thereby enabling the wire harnesses on the swing arm mechanism to be switched one by one for processing.

[0021] Furthermore, the wire harness pressing type is one-to-one, one-to-many, or many-to-many pressing. When the number of wire harnesses to be pressed at a processing station is one, the paralleling mechanism at that processing station is used to transfer and place a single wire harness. When the number of wire harnesses to be pressed at a processing station is multiple, the paralleling mechanism at that processing station is used to parallelize multiple wire harnesses.

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

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

[0024] The pressing method of the present invention allows two sets of opposing wire harnesses to be pressed to be independently processed by paralleling and heat shrink tubing on the left and right processing positions respectively, and then pressed. The main body of the wire harness can be laid flat and orderly in the receiving groove, so that even if the wire harness is long, it is not easy to get tangled or knotted. This avoids the need for subsequent manual separation, saving time and effort and improving processing efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

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

[0036] S1. Install the waterproof plugs and terminals sequentially to the rear ends of multiple wire harnesses;

[0037] S2. The wire harnesses are conveyed one by one to the rear via the conveyor line 5. After the wire harnesses are conveyed to the set position, the wire cutting mechanism 6 cuts the wire harnesses. 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. The main body of the wire harness slides to the left into the receiving trough 12 of the left processing position 17 or to the right into the receiving trough 12 of the right processing position 18 according to the set requirements. The main body of the wire harness refers to the part other than the front end of the wire harness.

[0038] S3. The first conveying mechanism 8 of the left and right processing positions respectively clamps the front end of the wire harness of the corresponding processing position and moves it to the paralleling mechanism 7 of the corresponding processing position. The paralleling mechanism 7 performs paralleling processing on multiple wire harnesses located in the same processing position or transfers and places a single wire harness.

[0039] S4. The second transport mechanism 9 of the left and right processing positions respectively clamps the front end of the wire harness of the corresponding processing position and transports it to the tube insertion mechanism 14. 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 mechanism 10 of the left and right processing positions respectively clamps the front end of the wire harness of the corresponding processing position and transports it to the pressing mechanism 13. The pressing mechanism 13 presses the front ends of the wire harness of the two corresponding 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. The heat shrink mechanism 15 heat shrinks the heat shrink tube on the wire harness. Then, the fourth transport mechanism 11 transports the wire harness backward to the take-up platform 16 for unified collection.

[0042] This pressing method allows the two sets of opposing wire harnesses to be pressed to be independently processed and heat-shrink tubing-fitted at the processing positions on the left and right sides, respectively, before being pressed together. The main body of the wire harness can be laid relatively orderly and flat in the receiving trough 12. Even if the wire harness is long, it is not easy for it to become tangled or knotted, thus avoiding the need for subsequent manual separation operations, saving more time and effort, and improving processing efficiency.

[0043] Step S1 further includes the following steps:

[0044] S1.1. Multiple wire harnesses are fed side by side to the swing arm device 3 through the infeed device 1. The swing arm device 3 rotates to move the rear ends of the multiple wire harnesses to the waterproof plug fitting device 4. The waterproof plug fitting device 4 fits the waterproof plug to the rear end of the corresponding wire harness.

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

[0046] That is, by rotating the swing arm device 3, the wire harness is switched to the waterproof plug sleeve device 4 and the terminal crimping device 2 respectively for the corresponding processing work, which makes the operation more convenient and occupies less space.

[0047] The waterproof plug fitting device 4 includes a first conveying mechanism 41, a first material handling and transfer mechanism 42, a first assembly mechanism 43, a second conveying mechanism 44, a second material handling and 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 fitting devices 4, and each waterproof plug fitting device 4 can fit two different types of waterproof plugs. The two waterproof plug fitting devices 4 can fit up to four different types of waterproof plugs. Step S1.1 also includes the following steps:

[0048] S1.1.1 First, the first type of waterproof plug is connected. The first assembly mechanism 43 and the first wire harness on the swing arm device 3 are both in the connection position and are set opposite to each other. The first type of waterproof plug is conveyed by the first conveying mechanism 41. Then, the first type of waterproof plug is taken out from the first conveying mechanism 41 and transferred to the first assembly mechanism 43 by the first material transfer mechanism 42. Then, the first type of waterproof plug is connected to the first wire harness by the first assembly mechanism 43.

[0049] S1.1.2 Then, the second type of waterproof plug is connected. The swing arm device 3 moves to move the second wire harness to the connection position. The second type of waterproof plug is conveyed by the second conveying mechanism 44. Then, the second type of waterproof plug is taken out from the second conveying mechanism 44 by the second material transfer mechanism 45 and transferred to the second assembly mechanism 46. The switching mechanism 47 drives the second assembly mechanism 46 to move to the connection position and set opposite to the second wire harness. Then, the second type of waterproof plug is connected to the second wire harness by the second assembly mechanism 46.

[0050] This method enables the waterproof plug fitting device 4 to automatically and quickly switch between two different specifications of waterproof plugs and fit them onto the corresponding different types of wire harnesses. It has high versatility, fast production efficiency, and does not require disassembly or replacement of the waterproof plug fitting device 4, thus saving economic costs.

[0051] Among them, the waterproof plug sleeve device 4 and the terminal crimping device 2 are arranged on the periphery 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 drivenly connected to the rotating disk 34. Multiple wire clamps 36 for clamping wire harnesses are arranged side by side on the swing arm mechanism 35. A slide rail 37, a slider 38 and a connector 39 are arranged on the bottom side of the swing arm mechanism 35. The connector 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 axis of the second drive module 33 passes through the clearance through hole and is connected to the slider 38.

[0052] When the first drive module 32 is started independently, the first drive module 32 drives the rotary disk 34 to rotate, which in turn drives the swing arm mechanism 35 to rotate, thereby enabling the wire harness to switch to different workstations for processing.

[0053] When the first drive module 32 and the second drive module 33 start simultaneously, they cooperate to drive the swing arm mechanism 35 to move back and forth, thereby enabling the wire harnesses on the swing arm mechanism 35 to be processed one by one. The first drive module 32 and the second drive module 33 are motor structures.

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

[0055] The wire harness pressing type is one-to-one, one-to-many, or many-to-many pressing. When the number of wire harnesses to be pressed at the processing station is one, the paralleling mechanism 7 at the processing station is used to transfer and place a single wire harness. When the number of wire harnesses to be pressed at the processing station is multiple, the paralleling mechanism 7 at the processing station is used to parallelize multiple wire harnesses.

[0056] In this embodiment, each conveying mechanism is a conveying gripper structure.

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

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