Transmitting electricity from one location to another can ensure that equipment and machines can work properly, and transmitting signals is used for communication between devices. In order to provide a more reliable and stable electrical connection and ensure reliable conductivity between each wire, welding the wire harness can reduce the contact resistance and improve the stability of the connection;

[0003] It mainly includes a welding head, a transportation device, a positioning device, a control device, and a monitoring device. The welding head is used to weld the wire harness, the transportation device is used to transport the wire harness to achieve the continuity of welding, the positioning device is used to position the wire harness to ensure stability during the welding process and avoid the deviation of the welding position. The control device can drive the welding head to move, thereby welding the wire harness, and the monitoring device is used to monitor the welding quality, temperature, and pressure to ensure the reliability of welding;

[0022] A welding method for harness production and processing, including:

[0023] Step 1: Fix the wire to be welded inside the mounting plate. Then place the mounting plate inside the feeding rack. The electric telescopic rod can drive the ultrasonic welding head to descend. After the ultrasonic welding head descends, the motor drives the bidirectional threaded rod to rotate, thereby driving the second moving plate to move. The movement of the second moving plate can drive the push plate to move, so as to push the wire to be welded into the inside of the welding plate. Then the ultrasonic welding head welds the wire.

[0024] Step 2: When the ultrasonic welding head descends to weld the wire, it can drive the pressing plate to descend. The pressing plate can drive the rack plate to descend when it descends. The descent of the rack plate can compress Spring 1. When the wire welding is completed, the ultrasonic welding head drives the pressing plate to rise to release the pressing on the rack plate, and then drives the rack plate to rise by the elasticity of Spring 1. The rise of the rack plate can drive the gear to rotate. The rotation of the gear can drive the rotating shaft to rotate through the cooperation of the baffle and the baffle. The rotation of the rotating shaft can drive the conveyor belt to rotate. The rotation of the conveyor belt can drive the connecting plate to move;

[0025] Step 3: The movement of the connecting plate can drive the fixed plate to move, and then drive the mounting plate inside the fixed plate to move. During the movement of the mounting plate, the two wires to be welded can be brought into contact through the cooperation of the first convex plate, so as to be welded. At the same time, the fixed plate inside the feeding rack falls into another fixed plate again to ensure the continuity of the welding device;

[0026] Step 4: The welded wire continues to move with the conveyor belt. When it reaches the first blanking port, it can squeeze the moving block to move through the second convex plate. The movement of the moving block can drive the rotating plate to rotate. The rotation of the rotating plate can drive the first moving plate to move. The movement of the first moving plate can drive the first rubber block to move. The movement of the first rubber block can make the wire fall off from the inside of the mounting plate, and then the wire falls into the inside of the workbench through the first blanking port. And the wire continues to move with the conveyor belt and falls into the inside of the workbench again when it passes through the second blanking port, thus completing the blanking of the wire.

[0027] The beneficial effects of the present invention:

[0028] (1) In the present invention, the wire harness to be welded can be fixed inside the mounting plate, and then placed inside the feeding rack. When the conveyor belt operates to transport the wire harness, the mounting plate inside the feeding rack can fall on the wire harness. At the same time, when the conveyor belt transports the wire harness to reach the first blanking port, squeezing the moving block through the second convex plate can make the wire harness at the first blanking port fall off from the current mounting plate and fall into the inside of the workbench through the first blanking port. Then the mounting plate continues to be transported with the conveyor belt and falls into the inside of the workbench through the second blanking port, so as to realize the welding of multiple wire harnesses. It can not only fix multiple wire harnesses before welding, but also automatically complete the separation of the wire harness after welding.

[0029] (2) The present invention drives the rack plate to rise through the elastic force of spring one, and then drives the gear to rotate. Through the cooperation of the baffle and spring two, the conveyor belt is driven to rotate, so as to transport the wire harness. During the transportation process, the mounting plate can be moved through the first convex plate, so that the two wire harnesses to be welded are in contact. When it enters the welding area, the ultrasonic welding head is driven to descend by the electric telescopic rod to complete the welding of the wire harness. During welding, spring one can be compressed, and after welding is completed, the conveyor belt can continue to operate through the reset elastic force of spring one, which can not only ensure the accuracy of welding, but also simplify the welding steps of the operator, thereby improving the welding efficiency.

[0030] (3) The present invention can drive the bidirectional threaded rod to rotate through the motor. The bidirectional threaded rod can drive the second moving plate to move through rotation. The second moving plate can drive the pushing plate to move through movement. The pushing plate can push the wire into the welding area inside the welding plate through movement, so as to complete the positioning of the wire harness during movement, ensure that the area where the wire harness needs to be welded can be welded, and ensure the accuracy of the welding process, further improving the precision and stability of welding.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0049] Please refer to Figure 1 - Figure 14As shown in the figure, the present invention is a welding device and a welding method for wire harness production and processing, including a workbench 1.

On the top side inside the workbench 1, there is a conveying component 2. On one side of the top of the workbench 1, there is a feeding component 3. Inside the workbench 1, there is a blanking component 4. The conveying component 2 is used to convey the wire harness, ensuring the continuity of wire harness welding and improving the processing efficiency. The feeding component 3 can fix multiple wire harnesses and position them during transportation by the conveying component 2 to ensure the stability of welding. The blanking component 4 is used to blank the welded wire harness. The adjustment component 6 ensures that the wire harness enters the welding area and ensures the accuracy of welding.

[0050] The conveying component 2 includes two conveyor belts 21, which are respectively arranged on the left and right sides of the top of the workbench 1. On one side of the conveyor belt 21, there is a fixed connection with a rotating shaft 22. On the outer wall of the rotating shaft 22, there is a rotatable connection with a gear 23. On the left and right sides of the top of the workbench 1, there are sliding connections with rack plates 24. The rack plates 24 are meshed with the gear 23. On the left and right sides of the ultrasonic welding head 14, there are fixed connections with pressing plates 25. The bottom of one side of the pressing plate 25 abuts against the top of the rack plate 24. On the outer wall of the rotating shaft 22, there are rotatable connections with a plurality of uniformly distributed baffle plates 27. One side of the baffle plate 27 abuts against the inside of the gear 23. At the bottom of the rack plate 24, there is a fixed connection with a first spring 26, and the bottom end of the first spring 26 is fixed to the inside of the workbench 1.

[0051] When the ultrasonic welding head 14 descends, it can drive the pressing plate 25 to descend. The pressing plate 25 can press the rack plate 24 through descending. The rack plate 24 can squeeze the first spring 26 through descending. When the ultrasonic welding head 14 rises and drives the pressing plate 25 to rise, after releasing the pressing on the rack plate 24, the elastic force of the first spring 26 can drive the rack plate 24 to rise. The rack plate 24 can drive the gear 23 to rotate through rising. The rotation of the gear 23 can drive the conveyor belt 21 to rotate through the cooperation of the baffle plate 27 and the second spring 28.

[0052] The feeding component 3 includes two feeding racks 31, both of which are fixedly connected to one side of the top of the workbench 1.

When the conveyor belt 21 operates, it can drive the connecting plate 32 to move. The connecting plate 32 can drive the fixing plate 33 to move through the movement, and the fixing plate 33 moves to drive the electric wire 35 inside it to move. At the same time, the installation plate 34 inside the feeding rack 31 falls into another fixing plate 33 again, which not only completes the continuity of transportation and processing, but also completes automatic feeding, reduces human intervention, and improves work efficiency.

[0053] The blanking component 4 includes a first blanking port 41 and a second blanking port 42. Both the first blanking port 41 and the second blanking port 42 are arranged inside the workbench 1. A second convex plate 43 is fixedly connected to the top side inside the workbench 1. A moving block 44 is slidably connected inside the installation plate 34. When the moving block 44 is squeezed when it moves to the second convex plate 43, the electric wire 35 can be separated from inside the installation plate 34; when the welded electric wire 35 moves to the first blanking port 41 along with the operation of the conveyor belt 21, the moving block 44 is squeezed by the second convex plate 43 to move. After the moving block 44 moves, the electric wire 35 can be separated from the current installation plate 34, thereby completing the automatic separation of the installation plate 34 and the electric wire 35, and making the electric wire 35 fall separately inside the workbench 1, while the installation plate 34 continues to move along with the conveyor belt 21 and falls to the other side of the workbench 1 through the second blanking port 42.

[0057] The fixing frame 11 is used to fix the fixing block 12. The fixing block 12 is used to fix the electric telescopic rod 13. The electric telescopic rod 13 is used to drive the ultrasonic welding head 14 to lift and lower. The welding plate 15 is used to provide a welding area. The spring IV 65 can prevent the ultrasonic welding head 14 from damaging the push plate 64 and the welding plate 15 when descending through its elastic force. The slide rod II 66 is used to fix the moving route of the moving plate II 63.

[0058] Both sides inside the moving plate I 46 are slidably connected with slide rods I 49. The slide rods I 49 are fixedly connected inside the mounting plate 34.

On both sides of the top of the workbench 1, a first convex plate 37 is fixedly connected. The side of the first convex plate 37 abuts against one side of the mounting plate 34. On the side of the baffle 27 away from the gear 23, a second spring 28 is fixedly connected. The end of the second spring 28 away from the baffle 27 is fixedly connected to the outer wall of the rotating shaft 22. The stabilizing block 36 makes the fixed plate 33 move more smoothly during the movement. The first convex plate 37 is used to adjust the position of the mounting plate 34 so that the two wires 35 to be welded are in contact. The second spring 28 can drive the baffle 27 to reset through its elastic force.

[0061] A welding method for wire harness production and processing includes:

[0062] Step 1: Fix the wire 35 to be welded inside the mounting plate 34. Then place the mounting plate 34 inside the feeding rack 31. The ultrasonic welding head 14 can be driven to descend by the electric telescopic rod 13. After the ultrasonic welding head 14 descends, the bidirectional threaded rod 62 is rotated by the motor 61 to drive the second moving plate 63 to move. The movement of the second moving plate 63 can drive the pushing plate 64 to move, thereby pushing the wire 35 to be welded into the welding plate 15. Then the wire 35 is welded by the ultrasonic welding head 14.

[0063] Step 2: When the ultrasonic welding head 14 descends to weld the wire 35, it can drive the pressing plate 25 to descend. The descent of the pressing plate 25 can drive the rack plate 24 to descend. The descent of the rack plate 24 can compress the first spring 26. When the wire 35 is welded, the ultrasonic welding head 14 drives the pressing plate 25 to rise to release the pressing on the rack plate 24. Then the rack plate 24 is driven to rise by the elastic force of the first spring 26. The rise of the rack plate 24 can drive the gear 23 to rotate. The rotation of the gear 23 can drive the rotating shaft 22 to rotate through the cooperation of the baffle 27 and the baffle 27. The rotation of the rotating shaft 22 can drive the conveyor belt 21 to rotate. The rotation of the conveyor belt 21 can drive the connecting plate 32 to move.

[0064] Step 3: The movement of the connecting plate 32 can drive the fixed plate 33 to move, and further drive the mounting plate 34 inside the fixed plate 33 to move. During the movement of the mounting plate 34, through the cooperation of the first convex plate 37, the two wires 35 to be welded can be brought into contact, so as to perform welding. At the same time, the fixed plate 33 inside the feeding frame 31 falls into another fixed plate 33 again, ensuring the continuity of the welding device;

[0065] Step 4: The welded wire 35 continues to move along the conveyor belt 21. When it reaches the first discharge opening 41, it can squeeze the moving block 44 to move through the second convex plate 43. The moving block 44 can drive the rotating plate 45 to rotate through movement. The rotating plate 45 can drive the first moving plate 46 to move through rotation. The first moving plate 46 can drive the first rubber block 47 to move through movement. The first rubber block 47 can make the wire 35 fall off from inside the mounting plate 34 through movement. Then, the wire 35 falls into the inside of the workbench 1 through the first discharge opening 41, and the wire 35 continues to move along the conveyor belt 21. When it passes through the second discharge opening 42, it falls into the inside of the workbench 1 again, thus completing the discharging of the wire 35.

[0066] Working principle of the present invention: Fix multiple wires 35 to be welded inside the mounting plate 34. Then, place the mounting plate 34 containing the wires 35 inside the feeding rack 31. Subsequently, the mounting plate 34 falls inside the fixed plate 33. First, drive the ultrasonic welding head 14 to descend by the electric telescopic rod 13, and drive the bidirectional threaded rod 62 to rotate by the motor 61, thereby driving the second moving plate 63 to move. The movement of the second moving plate 63 can drive the push plate 64 to move, so as to push the wires 35 to be welded into the welding area inside the welding plate 15. Then, drive the ultrasonic welding head 14 to descend again by the electric telescopic rod 13. The descent of the ultrasonic welding head 14 can drive the pressing plate 25 to descend. The descent of the pressing plate 25 drives the rack plate 24 to descend, thereby squeezing the first spring 26. At the same time, the descent of the ultrasonic welding head 14 completes the welding of the wires 35. After welding is completed, drive the ultrasonic welding head 14 to ascend by the electric telescopic rod 13, thereby releasing the pressing on the rack plate 24. After the pressing is released, the elastic force of the first spring 26 can drive the rack plate 24 to ascend. The ascent of the rack plate 24 drives the gear 23 to rotate, and drives the rotating shaft 22 to rotate through the cooperation of the baffle 27 and the second spring 28. The rotation of the rotating shaft 22 drives the conveyor belt 21 to operate. The operation of the conveyor belt 21 drives the connecting plate 32 to move, thereby driving the fixed plate 33 to move, so as to complete the transportation of the wires 35. During the transportation process, the mounting plate 34 inside the feeding rack 31 falls into the next fixed plate 33 again. When the welded wires 35 move to the first discharge opening 41 along with the operation of the conveyor belt 21, the moving block 44 is driven to move by the extrusion of the second convex plate 43. The movement of the moving block 44 drives the rotating plate 45 to rotate. The rotation of the rotating plate 45 drives the first moving plate 46 to move, thereby driving the first rubber block 47 to move. The movement of the first rubber block 47 can release the extrusion of the wires 35, so that the wires 35 fall between the first rubber block 47 and the second rubber block 48, thereby completing the automatic separation of the mounting plate 34 and the wires 35, and enabling the wires 35 to fall separately onto the workbench 1. The mounting plate 34 continues to move along with the operation of the conveyor belt 21 and falls onto the other side of the workbench 1 through the second discharge opening 42, completing the separation of the wires 35, simplifying the welding steps of the operator, and thus improving the welding efficiency.
