[0032] In order to more clearly illustrate the embodiments of the present application, the specific implementation methods of the present application will be described below with reference to the accompanying drawings.

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 feeding mechanism, including a fixed plate 1, a conveying trough 2, a transfer component 3 and a positioning component 4. The conveying trough 2 is installed on the fixed plate 1, and the terminal A is installed in the conveying trough 2. The positioning component 4 is used to position several terminals A on the terminal chain, and the transfer component 3 is used to sequentially convey several terminals A to the welding station for welding and forming the wire harness and the terminal.

[0035] Specifically, the transfer assembly 3 is connected to the fixed plate 1 and contacts and cooperates with the terminal A, and is used to sequentially transfer the plurality of terminals A in the conveying trough 2. The transfer assembly 3 includes a driving part, a moving seat 33 and a lifting block 34, wherein the driving part is connected to the moving seat 33, and the lifting block 34 is installed on the moving seat 33, and the lifting block 34 contacts and cooperates with the terminal A.

[0036] Furthermore, the driving part includes a first driving member 31 and a second driving member 32. The first driving member 31 is installed on the fixed plate 1. The driving direction of the first driving member 31 is horizontal and is consistent with the conveying direction of the terminals in the conveying groove 2. The first driving member 31 is used to drive the movable seat 33 to move horizontally; the second driving member 32 is installed in the movable seat 33. The driving direction of the second driving member 32 is vertical and is perpendicular to the conveying direction of the terminals. The second driving member 32 is used to drive the lifting block 34 to move up and down.

[0037] The first driving member 31 and the second driving member 32 are both cylinders, which can save the use cost by using the cylinders as the power source. It should be noted that the power source can also be a motor or an electric cylinder to improve the control accuracy, which can be set according to actual needs.

[0038] This embodiment also includes a guide assembly 5, which includes a slide rail 51 and a slider 52. The slide rail 51 is installed on the fixed plate 1, and the slider 52 slides with the slide rail 51. The slide rail 51 is arranged in a horizontal direction, and the arrangement direction of the slide rail 52 is consistent with the conveying direction of the terminal in the conveying groove 2.

[0039] Furthermore, the movable seat 33 is connected to the slider 52, the output end of the first driving member 31 is connected to the fixed block, the fixed block is fixedly connected to the movable seat 33, and the fixed block is driven to move by the first driving member 31 to link the movable seat 33 to move horizontally along the slide rail 51, so as to provide power for the lifting block 34 to transfer the terminals in the conveying groove 2.

[0040] In this embodiment, each terminal A has a welding position A and a connecting position A2. The welding position A is used for welding with the wire harness. The connecting position A2 has a positioning hole A3 for positioning when conveying the transfer terminal.

[0041] Furthermore, the lifting block 34 includes a lift pin 341 and a clamping block 342, the clamping block 342 is arranged between the two welding positions A1, and the lift pin 341 is inserted into the positioning hole A3; when conveying and transferring the terminal, the lift pin 341 needs to be inserted into the positioning hole A3, and at the same time, the clamping block 342 is inserted between the two welding positions A1, and then the first driving member 31 is moved to drive the terminal chain to move as a whole, and the terminal in front of the terminal chain is transferred to the welding station for the welding position of the terminal and the wiring harness to be welded and formed.

[0042] The positioning assembly 4 in this embodiment is connected to the fixing plate 1 and plugged with the terminal A to position the terminal A. The positioning assembly 4 includes a mounting seat 41, a third driving member 42 and a positioning pin 43, the third driving member 42 is connected to the mounting seat 41, the mounting seat 41 is connected to the fixing plate 1, and the third driving member 42 is in driving connection with the positioning pin 43.

[0043] The positioning pin 41 is driven by the third driving member 42 to move up and down and engage with the positioning hole A3 of the terminal, so as to position the terminal chain, prevent the terminal from tilting or deviating on the conveying trough 2, and ensure that the terminal always maintains a horizontal positioning on the conveying trough 2, so that the terminal chain can be guided by the positioning pin 41, and several terminals on the terminal chain can be automatically transferred to the welding station.

[0044] It should be noted that the third driving member 42 uses a cylinder as a power source, which can save usage costs. A motor or electric cylinder can also be used to improve control accuracy. The specific setting can be made according to actual needs.

[0045] The conveying trough 2 in this embodiment is provided with a first slide groove 21 and a second slide groove 22, the block 342 moves along the first slide groove 21, and the ejector pin 341 moves along the second slide groove 22. The first slide groove 21 and the second slide groove 22 are respectively used to limit the horizontal movement range of the block 342 and the ejector pin 341, and further, the horizontal movement distance of the block 342 and the ejector pin 341 is the spacing between the two terminals A.

[0046] In the chain terminal conveying process, when the front terminal is transferred to the welding station and welded with the wire harness, the subsequent terminal pushes out the terminal chain through the positioning pin, and automatically moves forward and transfers a terminal spacing through the cooperation of the first drive member and the second drive member. The front terminal to be welded can fall directly on the welding station, and the feeding work is completed immediately, which improves the terminal movement speed, realizes the continuous automatic feeding function, ensures the continuity of the action, provides convenience for the welding of the wire harness and the terminal, and thus improves the welding efficiency of the wire harness and the terminal.
