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

[0002] Existing wire harness crimping equipment is prone to tangling when crimping long wire harnesses, requiring manual separation. Some wire harnesses also have knots that are difficult to separate, which is time-consuming and labor-intensive. Furthermore, traditional wire harness crimping equipment cannot perform different types of terminal crimping or waterproof plugging on multiple different types of wire harnesses delivered in the same batch, thus affecting processing efficiency. Summary of the Invention

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

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: a wire harness crimping device, comprising a swing arm device and a wire inlet device, a terminal crimping device, a waterproof plug sleeve device, and a crimping device disposed on the periphery of the swing arm device.

The swing arm device is used to drive the wire harness to rotate to the terminal crimping device, the waterproof plug sleeve device and the pressing device respectively for corresponding processing operations. The terminal crimping device is used to crimp the terminal to the rear end of the wire harness, and the waterproof plug sleeve device is used to sleeve the waterproof plug to the rear end of the wire harness.

[0006] The pressing device includes a conveying mechanism, a receiving trough, a wire cutting mechanism, a handling mechanism, a tube threading mechanism, and a pressing mechanism. A first processing position and a second processing position are respectively arranged on both sides along the conveying direction within the pressing device. The conveying mechanism is located between the first and second processing positions and is used to convey the wire harness. The wire cutting mechanism is located between the swing arm device and the conveying mechanism and is used to cut the wire harness. The receiving trough, handling mechanism, and tube threading mechanism are in two sets, respectively located within the first and second processing positions. The two receiving troughs are located below the sides of the conveying mechanism and are used to receive the wire harnesses sliding down from both sides of the conveying mechanism. The tube threading mechanism and the pressing mechanism are located above the conveying mechanism. The pressing mechanism is used to press the front ends of the wire harnesses after tube threading at the first and second processing positions. The handling mechanism is used to clamp the front ends of the wire harnesses at the corresponding processing positions and sequentially transport them to the respective processing mechanisms for the corresponding processing operations.

[0007] Preferably, the pressing device further includes two paralleling mechanisms respectively disposed in the first processing position and the second processing position. The paralleling mechanisms are located between the wire cutting mechanism and the tube threading mechanism. The paralleling mechanisms are used to perform paralleling processing on the wire harness at their processing positions.

[0008] Preferably, the pressing device further includes a heat shrinking mechanism and a take-up carrier located behind the pressing mechanism.

Multiple wire clamps for clamping wire harnesses are arranged side by side along the second direction on the swing arm mechanism. A slide rail, a slider and a connector are provided 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 along the first direction. The output axis of the second drive module passes through the clearance through hole and is connected to the slider.

[0012] 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.

[0013] When the first drive module and the second drive module start simultaneously, the first drive module and the second drive module cooperate to drive the swing arm mechanism to move back and forth along the second direction, so that the wire harnesses on the swing arm mechanism can be switched one by one for processing.

[0014] Preferably, the waterproof plug fitting device includes a frame, on which a first and a second waterproof plug assembly unit and a switching mechanism are respectively provided. The first and second waterproof plug assembly units are used to fit different types of waterproof plugs onto different types of wire harnesses. The first and second waterproof plug assembly units have the same structural principle.

[0015] Preferably, the first waterproof plug assembly unit includes a first conveying mechanism and a first assembly mechanism that are connected to each other. A first transfer mechanism is provided above the first conveying mechanism and the first assembly mechanism for taking out the waterproof plug from the first conveying mechanism and transferring it to the first assembly mechanism.

[0016] The second waterproof plug assembly unit includes a second conveying mechanism and a second assembly mechanism that are connected to each other. A second material transfer mechanism is provided above the second conveying unit and the second assembly mechanism for taking out the waterproof plug from the second conveying mechanism and transferring it to the second assembly mechanism.

[0017] The first assembly mechanism and the second assembly mechanism are jointly mounted on the switching mechanism. The switching mechanism drives the first assembly mechanism and the second assembly mechanism to move telescopically together, thereby enabling the first assembly mechanism and the second assembly mechanism to switch and perform corresponding types of waterproof plug connection work with the wire harness on the swing arm device.

[0018] Preferably, the first conveying mechanism includes a material box, a vacuum suction pipe, and a vibrating feeding mechanism. The inlet end of the vacuum suction pipe is inserted into the material box, and the outlet end of the vacuum suction pipe is connected to the conveying head end of the vibrating feeding mechanism. The vacuum suction pipe draws the waterproof plugs from the material box and conveys them to the conveying head end of the vibrating feeding mechanism. The vibrating feeding mechanism is used to adjust the waterproof plugs to a vertical position for conveying.

[0019] Preferably, the length direction of the wire harness crimping equipment is defined as the front-to-back direction, the width direction as the left-to-right direction, the wire feeding device and the conveying mechanism are respectively set on the front and back sides of the swing arm device, the wire harness is conveyed from front to back, the first processing position and the second processing position are set side by side, and there are multiple waterproof plug sleeve devices and terminal crimping devices of different types.

[0020] Preferably, the conveying mechanism includes a first, second, third, and fourth conveying gripper.

The second conveying gripper is located between the paralleling mechanism and the pressing mechanism. The third conveying gripper is movably disposed between the pressing mechanism and the heat shrinking mechanism. The fourth conveying gripper is movably disposed between the third conveying gripper and the take-up platform.

[0021] The present invention has the following beneficial effects:

[0022] (1) By setting the infeed device, terminal crimping device, waterproof plug fitting device, and pressing device on the periphery of the swing arm device, the rotation of the swing arm device causes the wire harness to move to the terminal crimping device, waterproof plug fitting device, and pressing device respectively for corresponding processing operations. This allows multiple different types of wire harnesses conveyed in the same batch on the swing arm device to perform different types of terminal crimping or waterproof plug fitting operations. Furthermore, through the first and second processing positions arranged side by side, the conveying mechanism is located between the first and second processing positions. The receiving trough, conveying mechanism, and pipe threading mechanism are in two sets. The tube-connecting mechanism is respectively set in the first and second processing positions. The two receiving troughs are located on both sides below the conveying mechanism. The tube-threading mechanism and the pressing mechanism are located above the conveying mechanism. Through the arrangement of the processing mechanisms inside the pressing device, the wire harness can slide down to both sides into the receiving troughs on both sides and perform corresponding processing steps at the first and second processing positions. Finally, the pressing mechanism performs one-to-one, one-to-many, or many-to-many wire harness pressing processing, thereby effectively avoiding the occurrence of winding and thus avoiding subsequent manual separation operations, saving more time and effort, and improving processing efficiency.

[0023] (2) The first drive module is started independently, which drives the rotary table to rotate, thereby driving the swing arm mechanism to rotate, thus allowing the wire harness to switch to different workstations for processing; the first drive module and the second drive module are started simultaneously, which drives the swing arm mechanism to move back and forth along the second direction, thus allowing the wire harnesses on the swing arm mechanism to be switched one by one for processing. On the one hand, this allows the wire harness to be quickly switched to different processing devices for different processes; on the other hand, it allows multiple wire harnesses to be quickly switched on the same processing device to achieve the same process, thereby improving processing efficiency, and the overall structural layout is more reasonable and compact, occupying less space.

[0024] (3) The waterproof plug fitting device is a dual-station assembly structure, which can realize the automatic and rapid switching and conveying of two different specifications of waterproof plugs, and fit them on the corresponding different types of wire harnesses. It has high versatility, fast production efficiency, and no need to disassemble or replace the fitting device, thus saving economic costs. Attached Figure Description

[0036] See Figure 1-7 As shown, as an embodiment of the present invention, a wire harness crimping device is provided, including a swing arm device 3 and a wire inlet device 1, a terminal crimping device 2, a waterproof plug sleeve device 4 and a crimping device disposed on the periphery of the swing arm device 3.

[0037] The wire feeding device 1 is used to transport the wire harness to the swing arm device 3. The swing arm device 3 is used to drive the wire harness to rotate to the terminal crimping device 2, the waterproof plug sleeve device 4 and the pressing device respectively for corresponding processing operations. The terminal crimping device 2 is used to crimp the terminal to the rear end of the wire harness, and the waterproof plug sleeve device 4 is used to sleeve the waterproof plug to the rear end of the wire harness.

[0038] The pressing device includes a conveying mechanism 52, a receiving trough 12, a wire cutting mechanism 6, a wire paralleling mechanism 7, a handling mechanism, a tube threading mechanism 14, a pressing mechanism 13, a heat shrinking mechanism 15, and a take-up platform 16. A first processing position 17 and a second processing position 18 are respectively arranged on both sides along the conveying direction within the pressing device. The conveying mechanism 52 is located between the first processing position 17 and the second processing position 18 and is used to convey the wire harness. The wire cutting mechanism 6 is located between the swing arm device 3 and the conveying mechanism 52 and is used to cut the wire harness. The wire paralleling mechanism 7, the receiving trough 12, the handling mechanism, and the tube threading mechanism 14 are in two sets, with the two sets of wire paralleling mechanism 7, receiving trough 12, handling mechanism, and tube threading mechanism 14 respectively arranged at the first processing position 17 and the second processing position 18. Within the second processing station 18, the wire-joining mechanism 7 is located between the wire-cutting mechanism 6 and the tube-threading mechanism 14. The wire-joining mechanism 7 is used to perform wire-joining processing on the wires at its processing station. Two receiving troughs 12 are located below the two sides of the conveying mechanism 52, respectively. The two receiving troughs 12 are used to receive the wires that slide down from the two sides of the conveying mechanism 52. The tube-threading mechanism 14 and the pressing mechanism 13 are located above the conveying mechanism 52. The pressing mechanism 13 is used to press the front ends of the wires at the first processing station 17 and the second processing station 18 after tube threading. The heat-shrinking mechanism 15 and the take-up carrier 16 are arranged in sequence behind the pressing mechanism 13. The conveying mechanism is used to clamp the front ends of the wires at the corresponding processing station and transport them in sequence to each processing mechanism for the corresponding processing operation.

[0039] In this design, the length direction of the wire harness crimping device is defined as the front-to-back direction, and the width direction is defined as the left-to-right direction. The wire feeding device 1 and the conveying mechanism 52 are respectively set on the front and back sides of the swing arm device 3. The wire harness is conveyed from front to back. The first processing position 17 and the second processing position 18 are set side by side. Specifically, the crimping device is used to crimp the front ends of the wire harnesses on both sides of the conveying mechanism 52. The crimping type of the wire harnesses on both sides is one-to-one, one-to-many, or many-to-many crimping.

[0040] By arranging the infeed device 1, terminal crimping device 2, waterproof plug fitting device 4, and pressing device on the periphery of the swing arm device 3, and with multiple waterproof plug fitting devices 4 and terminal crimping devices 2 of different types, the rotation of the swing arm device 3 causes the wire harnesses to move to the terminal crimping device 2, waterproof plug fitting device 4, and pressing device respectively for corresponding processing operations. This allows multiple wire harnesses of different types transported in the same batch on the swing arm device 3 to undergo different types of terminal crimping or waterproof plug fitting operations. Furthermore, through the first processing position 17 and the second processing position 18 arranged side-by-side, the conveying mechanism 52 is located between the first processing position 17 and the second processing position 18. The paralleling mechanism 7, the receiving trough 12, the handling mechanism, and the pipe threading mechanism 14 are in two sets. The paralleling mechanism 7, the receiving trough 12, the conveying mechanism, and the tube threading mechanism 14 are respectively arranged in the first processing position 17 and the second processing position 18. The two receiving troughs 12 are located on both sides below the conveying mechanism 52, and the tube threading mechanism 14 and the pressing mechanism 13 are located above the conveying mechanism 52. That is, through the arrangement of the processing mechanisms inside the pressing device, the wire harness can slide down to both sides into the receiving troughs 12 on both sides and perform corresponding processing on the first processing position 17 and the second processing position 18 respectively. Finally, the pressing mechanism 13 performs one-to-one, one-to-many, or many-to-many wire harness pressing processing, thereby effectively avoiding the occurrence of winding phenomenon, thus avoiding subsequent manual separation operation, saving more time and effort, and improving processing efficiency.

[0041] In this embodiment, the pressing mechanism is a riveting mechanism or an ultrasonic welding mechanism, which can press the wire harness by riveting or ultrasonic welding to ensure the stability of the pressing.

[0042] In this embodiment, 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. The first drive module 32 and the second drive module 33 are motors. The length direction of the swing arm device 3 is the first direction, and the width direction is the second direction. The rotating disk 34 is rotatably mounted on the base 31. A clearance through hole is provided 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 along the second direction on the swing arm mechanism 35. A slide rail 37, a slider 38, and a connector 39 are provided 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 mounted on the slide rail 37 along the first direction. The output axis of the second drive module 33 passes through the clearance through hole and is connected to the slider. 38. Specifically, the first drive module 32 is connected to the rotary disk 34 via a synchronous belt, and the second drive module 33 is connected to the slider 38 via a horizontal swing arm 310. One end of the horizontal swing arm 310 is fixedly connected to the output shaft of the second drive module 33, and the other end is movably connected to the slider 38. When the first drive module 32 is started alone, it drives the rotary disk 34 to rotate, which in turn drives the swing arm mechanism 35 to rotate, thereby allowing the wire harness to switch to different workstations for processing. When the first drive module 32 and the second drive module 33 are started simultaneously, they cooperate to drive the swing arm mechanism 35 to move back and forth along the second direction, thereby allowing the wire harnesses on the swing arm mechanism 35 to be switched one by one for processing. 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.

[0043] In this embodiment, the waterproof plug fitting device 4 is a dual-station assembly structure. The waterproof plug fitting device 4 includes a frame 41, on which first and second waterproof plug assembly units and a switching mechanism 411 are respectively mounted.

The first and second waterproof plug assembly units have the same structural principle. Specifically, the first waterproof plug assembly unit includes a first conveying mechanism 42 and a first assembly mechanism 44 that are connected to each other. A first transfer mechanism 43 is provided above the first conveying mechanism 42 and the first assembly mechanism 44 to remove the waterproof plugs from the first conveying mechanism 42 and transfer them to the first assembly mechanism 44. The second waterproof plug assembly unit includes a second conveying mechanism 45 and a second assembly mechanism 411 that are connected to each other. The second conveying unit and the second assembly mechanism 47 are connected by a second transfer mechanism 46, which is used to remove the waterproof plugs from the second conveying mechanism 45 and transfer them to the second assembly mechanism 47. The first assembly mechanism 44 and the second assembly mechanism 47 are mounted together on the switching mechanism 411, which is a cylinder. The switching mechanism 411 drives the first assembly mechanism 44 and the second assembly mechanism 47 to move together, so that the first assembly mechanism 44 and the second assembly mechanism 47 can switch to connect with the wire harness on the swing arm device 3 to the corresponding type of waterproof plug. This setting can realize the automatic and fast switching and conveying of two different specifications of waterproof plugs and connect them to the corresponding different types of wire harnesses. It has high versatility, fast production efficiency, and does not require disassembly and replacement of the connecting device, thus saving economic costs.

[0044] In this embodiment, the first conveying mechanism 42 includes a material box 48, a vacuum suction pipe 49, and a vibrating feeding mechanism 410. The inlet end of the vacuum suction pipe 49 is inserted into the material box 48, and the outlet end of the vacuum suction pipe 49 is connected to the conveying head end of the vibrating feeding mechanism 410. The vacuum suction pipe 49 sucks up the waterproof plugs in the material box 48 and conveys them to the conveying head end of the vibrating feeding mechanism 410. The vibrating feeding mechanism 410 is used to adjust the waterproof plugs to a vertical position for conveying.

[0045] In this embodiment, the transport mechanism includes first, second, third, and fourth transport grippers 11. The first transport gripper 8 is movably disposed between the wire cutting mechanism 6 and the tube threading mechanism 14. The second transport gripper 9 is located between the wire bundling mechanism 7 and the pressing mechanism 13. The third transport gripper 10 is movably disposed between the pressing mechanism 13 and the heat shrinking mechanism 15. The fourth transport gripper 11 is movably disposed between the third transport gripper 10 and the take-up platform 16. The first, second, and third transport grippers 10 are all two sets facing each other. The first transport gripper 8 clamps the front end of the wire harness and transports it from the wire cutting mechanism 6 to the wire bundling machine. The wire harness is fused at point 7. The second transport gripper 9 clamps the front end of the wire harness and moves it from the fusion mechanism 7 to the tube insertion mechanism 14 for heat shrink tubing installation. Then it is moved to the pressing mechanism 13 to press the front ends of the wire harnesses on both sides. The third transport gripper 10 clamps the pressed wire harness and moves it to the front of the fourth transport gripper 11. The fourth transport gripper 11 clamps the pressed wire harness on the third transport gripper 10 and moves it to the heat shrinking mechanism 15 for heat shrink tubing operation. After that, the heat-shrinked wire harness is moved to the take-up platform 16 for unified collection and processing.

[0046] The present invention also provides a wire harness pressing process, including the wire harness pressing equipment described in the above embodiments, wherein the processing method includes the following steps:

[0047] S1. The infeed device 1 delivers multiple wire harnesses side by side to the swing arm device 3.

The waterproof plug fitting device 4 then fits the waterproof plug onto the rear end of the corresponding wire harness.

[0048] S2. The swing arm device 3 rotates to move multiple wire harnesses to the terminal crimping device 2, and the terminal crimping device 2 crimps the terminals to the rear end of the corresponding wire harnesses.

[0049] S3, the swing arm device 3 rotates to drive multiple wire harnesses to the pressing device. After the conveying mechanism 52 conveys the wire harnesses to the rear position, the wire cutting mechanism 6 cuts the wire harnesses. The conveying mechanism clamps and carries the front end of the wire harnesses. The wire harnesses slide to the left or right side into the receiving trough 12 of the first processing position 17 or the second processing position 18 according to the settings.

[0050] S4. The first transport grippers 8 of the two processing positions respectively pick up the front end of the wire harness at the corresponding processing position and transport it to the wire merging mechanism 7. The wire merging mechanism 7 merges multiple wire harnesses located at the same processing position.

[0051] S5. The second transport grippers 9 of the two processing positions respectively clamp the front end of the wire harness at the corresponding processing position and transport it to the tube threading mechanism 14. The heat shrink tubing is then sleeved on the front end of the wire harness through the tube threading mechanism 14.

[0052] S6. The third transport grippers 10 of the two processing positions respectively clamp the front end of the wire harness of the corresponding processing position and transport it to the pressing mechanism 13. The pressing mechanism 13 then rivets the front end of the wire harness of the two processing positions.

[0053] S7. The fourth transport gripper 11 clamps up the riveted wire harness and transports it to the heat shrinking mechanism 15, where the heat shrinking mechanism 15 performs heat shrinking treatment on the heat shrink tubing.

[0054] S8, the fourth transport gripper 11 clamps up the heat-shrinked wire harness and transports it to the take-up platform 16 for unified collection.
