[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0047] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0048] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0049] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application.

[0053] In use, the first feeding mechanism 3 places the empty fixture 2 onto the conveying mechanism 1, which then moves the fixture 2 to the next workstation. The second feeding mechanism 4 places copper bars onto the fixture 2, which then moves to the next workstation. The third feeding mechanism 5 places wire harnesses onto the fixture 2, which then moves to the next workstation. The closing mechanism 6 closes the fixture 2, which then moves to the next workstation. The coating mechanism 7 applies flux to the copper bars and wire harnesses, which then moves to the next workstation. Finally, the soldering mechanism 8 applies solder to the copper bars and wire harnesses. The device performs soldering, then moves to the next workstation. The cover-opening mechanism 9 opens the cover of the fixture 2, and the device moves to the next workstation. The unloading mechanism 10 first removes the soldered wire harness, and then the empty fixture 2 is removed and moved back to the first workstation via the conveying mechanism 1, thus repeating the process. This device can automate the assembly of wire harness terminals and copper strips, the application of flux and solder, etc., saving labor costs, improving production efficiency, and is stable and reliable, improving product consistency, increasing yield, and effectively ensuring the quality of finished products.

[0054] like Figure 2 and 3 As shown, in this embodiment, the fixture 2 includes a base 21, a positioning block 22, and a cover plate 23. The positioning block 22 is located on the base 21.

The base 21 is made of metal, and the cover plate 23 is a magnetic component that can be magnetically connected to the base 21.

[0055] like Figure 1 , 4 As shown in Figure 5, in this embodiment, the transmission mechanism 1 includes a first transmission component 11 and a second transmission component 12, wherein the transmission direction of the first transmission component 11 is opposite to the transmission direction of the second transmission component 12.

[0056] The first conveying assembly 11 includes a first support 111, a first drive motor 112, a first conveyor belt 113, a first transmission roller 114, and a plurality of first driven rollers 115.

The first drive motor 112 drives the first transmission roller 114 to rotate. The first conveyor belt 113 is driven and sleeved on the first transmission roller 114 and the first driven rollers. The first conveyor belt 113 is provided with a plurality of limiting grooves 116, and the fixture 2 is placed in the limiting grooves 116.

[0057] The second conveying assembly 12 includes a second support 121, a second drive motor 122, a second conveyor belt 123, a second transmission roller 124, and a plurality of second driven rollers 125.

The first conveyor belt 113 synchronously drives the first driven roller 115 to rotate. The first driven roller 115 supports the first conveyor belt 113, which in turn drives the fixture 2 to move. The limiting groove 116 keeps the position of the fixture 2 relatively fixed relative to the first conveyor belt 113 so that each workstation can carry out operations. Moreover, the limiting groove 116 can prevent the fixture 2 from shifting and falling during movement, thus improving the stability of use.

[0059] In use, the second drive motor 122 is turned on to drive the second transmission roller 124 to rotate. The second transmission roller 124 drives the second conveyor belt 123 to rotate. The second conveyor belt 123 synchronously drives the second driven roller 125 to rotate. The second driven roller 125 supports the second conveyor belt 123, which in turn drives the fixture 2 to move. When the fixture 2 moves back to the first workstation, it is blocked by the stop bar 127 and stays at the position of the first workstation so that the first feeding mechanism 3 can pick it up for repeated use. The two baffles 126 can prevent the fixture 2 from falling off the sides of the second conveyor belt 123 during movement, thus improving the stability of use.

[0063] In use, copper bars are pre-stacked and placed into the loading box 45. The first cylinder 48 is activated, causing the first pusher 47 to extend into the loading box 45 through the through hole 410, pushing the bottom layer of copper bars out of the loading box 45 through the discharge hole 49 and into the loading trough 46. Then, the first pusher 47 is reset, and under gravity, the stacked copper bars fall to the bottom for the next loading. Next, the fourth linear module 42 is activated, moving the second suction head 44 above the loading trough 46. The third linear module 41 is activated, causing the second suction head 44 to descend until it contacts the copper bars. The second vacuum generator is then activated.
