For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0033] In the description of the embodiments of the present application, the terms "upper", "lower", "front", "rear", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the application. In addition, the terms "first", "second", etc. are only used to distinguish in the description and have no special meaning.

[0034] like Figures 1 to 6 As shown, this embodiment provides a chain terminal welding tool, including a frame 1, a conveying plate 2, a positioning component 3 and a cutting component 4. The chain terminals on the conveying plate 2 are sequentially conveyed to the welding station, the wire harness and the terminal are welded into shape by ultrasonic welding, and the waste area of ​​the rear terminal after welding is cut off by the cutting component 4.

[0035] Specifically, the frame 1 includes a base 11 and a bottom plate 12 . The conveying plate 2 is disposed on the base 11 and is used to install the terminal A and the wire harness B so as to weld the welding position A1 of the terminal A with the wire harness B.

[0036] Furthermore, a collecting trough 5 is installed on the bottom plate 12 for collecting waste. The collecting trough 5 is detachably connected to the bottom plate 12. After a certain amount of waste is collected, the waste can be poured out or replaced by disassembling, which makes installation, disassembly or replacement more convenient.

[0037] Furthermore, a cutting position 111 is provided on the base 11 , and the cutting position 111 is arranged opposite to the material receiving slot 5 . When the cutting component 4 cuts off the waste of the terminal after welding, the waste is collected through the material receiving slot 5 .

[0038] The cutting assembly 4 in this embodiment is connected to the base 11, and is used to cut the welded terminal A to remove the waste area A2 of the terminal. The cutting assembly 4 includes a driving unit 41 and a cutting knife 42, and the driving unit 41 is used to drive the cutting knife 42 to move. The driving unit 41 uses a cylinder, and the cylinder is used as a power source to save the cost of use. It should be noted that the power source can also use a motor or an electric cylinder to improve the control accuracy, and can be set according to actual needs.

[0039] Furthermore, the base 11 is provided with a through slot 113 , and the cutter 42 moves up and down along the through slot 113 to cut off the waste area of ​​the terminal.

[0040] Specifically, the base 11 is provided with a guide rail 13, the driving unit 41 is connected to the front of the guide block 14, the cutter 42 is connected to the side wall of the guide block 14, and the guide block 14 is slidably connected to the guide rail 13. The driving unit 41 drives the guide block 14 to move up and down along the guide rail 13, and the guide block 14 drives the cutter 42 to move up and down along the through hole 113.

[0041] The positioning assembly 3 in this embodiment is installed on the base 11 and is used to position the terminal A on the conveying plate 2; the positioning assembly 3 includes a mounting seat 31, a moving block 32 and a positioning pin 33, the mounting seat 31 is slidably matched with the base 11, the moving block 32 is connected to the mounting seat 31, the moving block 32 is provided with a positioning pin 33, and the positioning pin 33 is in contact with the waste area A2 of the terminal A.

[0042] By driving the positioning pin 331 to move up and down and engage with the positioning hole on the waste area A2 of the terminal, the terminal chain is positioned to prevent the terminal from tilting or deviating on the conveying plate 2, ensuring that the terminal always remains horizontally positioned on the conveying plate 2, so that the terminal chain can be automatically transferred to the welding station under the positioning guidance of the positioning pin 33.

[0043] Furthermore, a slide rail 15 is provided on the base 11, and the mounting seat 31 is connected to the slider 16, and the slider 16 is slidably matched with the slide rail 15. When the terminal chain sequentially conveys each terminal to the welding station along the conveying plate 2, the mounting seat 31 moves along the slide rail 15, so that the positioning pin 33 sequentially positions the positioning holes on different terminals, thereby achieving real-time positioning of the terminal chain and ensuring welding stability.

[0044] A welding position 112 is provided on the base 11, and a bottom mold (not shown in the figure) is placed below the welding position 112. The bottom mold is used to support the terminal and the wiring harness. The top of the welding position 112 faces the ultrasonic welding head (not shown in the figure). The ultrasonic welding head presses down the wiring harness and the terminal and welds the two into shape.

[0045] The terminal A and the wiring harness B in this embodiment are arranged at an angle of 90 degrees, so that the welding position A1 of the terminal A and the wiring harness B can be welded into shape first, and then the waste area A2 on the welded terminal A can be cut and removed, thereby ensuring the continuity of the process and improving the welding efficiency of the wiring harness and the terminal.

[0046] The base in the embodiment of the present application includes a side plate arranged on the bottom plate and connected to the bottom plate, and a horizontal mounting plate installed on the side plate. The base and the bottom plate form an overall frame of the rack.
