Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, specifically to a fully automatic soldering device for wire harness terminals. Background Technology

[0002] During wire harness fabrication, soldering is necessary. Soldering strengthens the connection between the wire harness terminals and the wires, preventing loosening. This is crucial for ensuring the long-term stability of the electrical connection. Wire joints exposed to air are prone to oxidation, leading to increased resistance and affecting current transmission efficiency. The protective layer formed by soldering effectively prevents oxygen in the air from contacting the copper wire, thus reducing oxidation. Because tin has better conductivity than copper, soldering reduces the wire's resistance, which is beneficial for power transmission and reduces heat generation.

[0003] Existing soldering equipment cannot automate the picking, conveying, flipping and soldering processes. Wire harnesses cannot be soldered at specified angles and positions, thus failing to reduce the need for manual operation and shorten the production cycle. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , 2As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a fully automatic soldering device for wire harness terminals, comprising: an equipment box 1; two picking components located at both ends of the equipment box 1, namely a feeding picking component for feeding and a discharging picking component for discharging, each picking component including a first pneumatic gripper 7 for clamping the wire harness and a drive unit for rotating the first pneumatic gripper 7; a rotating component placed on the top of the equipment box 1, the rotating component being slidably mounted on a movable base 21 on the top of the equipment box 1, and a third motor 25 fixedly connected to the top of the movable base 21. The output end of motor 25 is fixedly connected to pneumatic gripper 22. The conveying assembly is placed on the top of the equipment box 1. The conveying assembly includes two pneumatic grippers 10 slidably disposed on the top of the equipment box 1. A connecting plate 11 is fixedly connected between the two pneumatic grippers 10. A conveying part is provided on one side of the connecting plate 11 for driving the pneumatic grippers 10 to move. The flipping assembly is placed in the middle of the equipment box 1. The flipping assembly includes two pneumatic grippers 17 for rotating the wire harness. A solder resist box 14 and a solder immersion tank 24 are respectively provided on the top of the equipment box 1 at the positions corresponding to the two pneumatic grippers 17.

[0027] It should be noted that this utility model is equipped with a PLC controller. During operation, the first pneumatic gripper 7 rotates around the output end of the first motor 5 under the action of the first motor 5. This gripper 7, in conjunction with the first pneumatic gripper 7, clamps the wire harness from one end. After the fourth pneumatic gripper 22 clamps the wire harness, the third motor 25 drives the wire harness to rotate 90 degrees via the fourth pneumatic gripper 22. The first pneumatic gripper 7 resets under the action of the first motor 5. The third cylinder 23 pushes the fourth pneumatic gripper 22 forward, pushing the wire harness held by the fourth pneumatic gripper 22 into the second pneumatic gripper 10. At this time, the other second pneumatic gripper 10 corresponds to the position of the solder resist box 14, and the second pneumatic gripper 10 clamps the wire... After the solder resist box 14 moves, the second pneumatic gripper 10 moves the wire harness to the third pneumatic gripper 17 located on one side of the solder resist box 14. At this time, another second pneumatic gripper 10 transports the wire harness, which has been dipped in the solder resist box 14, to the third pneumatic gripper 17 located on one side of the tin bath 24. The second rotating shaft 15 drives the two third pneumatic grippers 17 to rotate, thereby placing the wire harness in the solder resist box 14 and the tin bath 24 respectively. This achieves the following: after the wire harness comes into contact with the solder resist box 14, it is transported by the second pneumatic gripper 10 and then brought into contact with the molten solder inside the tin bath 24 by the other third pneumatic gripper 17. Then, the end-picking component clamps and rotates it to the remaining processes.

[0028] Please see Figure 4As shown, the drive unit includes a support frame 2. A first horizontal plate 3 and a second horizontal plate 4 are fixedly connected to the top of the support frame 2. A first motor 5 is fixedly connected to the top of the second horizontal plate 4. A rotating plate 6 is fixedly connected to the output end of the first motor 5. A first rotating shaft 8 is rotatably connected to the end of the rotating plate 6. A first pneumatic gripper 7 is fixedly connected to the bottom of the first rotating shaft 8. Transmission pulleys are fixedly connected to the outer sides of the first horizontal plate 3 and the first rotating shaft 8. Belts are sleeved on the outer sides of the two transmission pulleys.

[0029] It should be noted that in this invention, the first motor 5 drives the rotating plate 6 to rotate around the motor shaft. The rotating plate 6 drives the first pneumatic gripper 7 to swing via the first rotating shaft 8. During this process, the first pneumatic gripper 7 clamps the wire harness and rotates it. One transmission pulley is fixed to the first horizontal plate 3, and the other transmission pulley is rotatably set via the first rotating shaft 8. Due to the friction and traction of the belt, when the rotating pulley rotates around the fixed pulley, the belt is stretched and compressed, causing the rotating pulley to generate a torque and rotate. Thus, while the rotating plate 6 drives the wire harness to rotate around the first motor 5, the first pneumatic gripper 7 itself rotates to adjust the angle of the wire harness.

[0030] Please see Figure 2 As shown, a No. 3 cylinder 23 is fixedly connected to the top of the equipment box 1, and the output end of the No. 3 cylinder 23 is fixedly connected to the movable base 21.

[0031] It should be noted that, in this utility model, when the first pneumatic gripper 7 delivers the wire harness into the fourth pneumatic gripper 22, after the fourth pneumatic gripper 22 clamps the wire harness, the fourth pneumatic gripper 22 driven by the third motor 25 rotates. After the angle adjustment is completed, the third cylinder 23 drives the moving seat 21 to move forward, so that the fourth pneumatic gripper 22 places the wire harness into the second pneumatic gripper 10.

[0032] Please see Figure 6 As shown, the conveying unit includes a linear guide rail 9 fixed to the top of the equipment box 1 and a first transmission belt assembly 13 arranged parallel to the linear guide rail 9. The transmission belt of the first transmission belt assembly 13 is fixed to the connecting plate 11. The second pneumatic gripper 10 is slidably connected to the linear guide rail 9. A second motor 12 is fixed to the top of the equipment box 1. The output end of the second motor 12 is fixed to the pulley of the first transmission belt assembly 13.

[0033] It should be noted that both the first transmission belt assembly 13 and the second transmission belt assembly 16 of this utility model include two pulleys and a transmission belt sleeved on the outside of the two pulleys for driving the two pulleys. The equipment box 1 is equipped with multiple position sensors corresponding to the position of the second pneumatic gripper 10 to detect position changes of the second pneumatic gripper 10. The distance between the two second pneumatic grippers 10 is the same as the distance between the two third pneumatic grippers 17, and the distance between the two second pneumatic grippers 10 is the same as the distance between the solder resist box 14 and the fourth pneumatic gripper 22. Equally, when the No. 2 motor 12 drives the No. 1 transmission belt assembly 13 to rotate, the transmission belt drives the connecting plate 11 to slide on the outside of the linear guide rail 9. When one of the No. 2 pneumatic grippers 10 and the No. 4 pneumatic gripper 22 are working in coordination, the other No. 2 pneumatic gripper 10 is working in coordination with the No. 3 pneumatic gripper 17 near the side of the solder resist box 14. When the No. 2 motor 12 and the No. 1 transmission belt assembly 13 drive the connecting plate 11 to move forward to the next working position, the two No. 2 pneumatic grippers 10 are aligned with the two No. 3 pneumatic grippers 17, thus completing the coordination.

[0034] Please see Figure 3 As shown, the flipping assembly also includes a second rotating shaft 15 that is rotatably placed on top of the equipment box 1 via a bracket, a third pneumatic gripper 17 that is fixed to the end of the second rotating shaft 15, a second transmission belt assembly 16 that is provided in the middle of the second rotating shaft 15, and a drive motor that is installed at one end of the second transmission belt assembly 16.

[0035] It should be noted that the drive motor of this utility model is installed inside the equipment box 1. The drive motor is connected to the second rotating shaft 15 through the transmission belt assembly, so as to realize that the third pneumatic gripper 17 clamps the wire harness. Then the second rotating shaft 15 drives the third pneumatic gripper 17 to rotate, so that the wire harness can work with the corresponding solder resist box 14 or tin dipping bath 24.

[0036] Please see Figure 1 , 2 As shown in Figure 3, a first cylinder 18 is fixedly connected to the top of the equipment box 1. A second cylinder 20 is slidably connected to the top of the equipment box 1 via a guide rail and a slider. The second cylinder 20 is vertically arranged and its output end is fixedly connected to a push plate 19. A T-shaped block is fixedly connected to one end of the push plate 19. A T-shaped groove that mates with the T-shaped block is opened at the output end of the first cylinder 18. The T-shaped block slides up and down in the T-shaped groove. A baffle is fixedly connected to the top of the equipment box 1. A rectangular hole that mates with the push plate 19 is opened in the middle of the baffle. One side of the tin-immersion tank 24 is fixedly connected to the push plate 19, so that the tin-immersion tank 24 is suspended above the equipment box 1.

[0037] It should be noted that the second cylinder 20 of this utility model can move along the extension and retraction direction of the first cylinder 18 under the action of the guide rail and the slider. The top of the slider is fixedly connected to a metal rod that is slidably connected to the push plate 19, so as to ensure the stability of the push plate 19 when it is raised and lowered. In this way, the second cylinder 20 drives the push plate 19 to rise and fall, and the push plate 19 drives the tin-immersion tank 24 to rise and fall. One end of the first cylinder 18, under the action of the T-shaped block and the T-shaped groove, allows the first cylinder 18 to drive the push plate 19 to move laterally without affecting the rise and fall of the push plate 19. In this way, the first cylinder 18 can push the push plate 19 forward, and the push plate 19 drives the second cylinder 20 to move laterally at the top of the equipment box 1, so that the tin-immersion tank 24 moves closer to the position of the third pneumatic gripper 17. Furthermore, the second cylinder 20 can drive the push plate 19 to move by raising and lowering, and the push plate 19 drives the tin-immersion tank 24 to adjust its height.
