[0026] Specifically, by setting the accommodating groove 11 on the jig plate 1, during welding, the backlight plate is placed into the accommodating groove 11 for fixation, then the backlight baffle 2 is covered, then the pins 5 on the backlight plate are placed on the backlight baffle 2 to contact the backlight plate, then the wire row needed to be welded with the backlight plate is bent to the backlight baffle 2, then the wire row is fixed by pressing the welding baffle 3, wherein the welding baffle 3 protects the wire row from being accidentally scalded, and in addition, it should be noted that the welding baffle 3 is provided with a welding port 31, and after the welding baffle 3 is covered, the welding port 31 is located at the upper end of the pin 5 of the backlight plate, then cooperates with the top block 4 on one side of the welding port 31 to form an independent welding space, so that the welding is accurate and safe.

[0027] Referring to Figure 3 , the backlight baffle 2 is slidably connected with the jig plate 1, and can also be connected in a hinged manner, wherein the slidably connected manner occupies a larger space of the jig plate 1 and has a complex design; and the hinged connection manner only needs one end of the backlight baffle 2 to be fixed with the jig plate 1, occupies a smaller space of the jig plate 1, and when opened, the backlight baffle 2 is rotated around the hinge, thereby well utilizing the upper space, and compared with the slidably connected manner, the hinged connection manner is easy to operate and has a simple structure; preferably, one end of the backlight baffle 2 is hinged with the jig plate 1. In addition, it should be noted that in order to ensure that the backlight baffle 2 can be horizontal after being covered, the thickness of the backlight plate should be equal to or less than the depth of the accommodating groove 11.

[0028] Referring to Figure 4 , further, the backlight baffle 2 comprises a welding part 21 and an isolation part 22, the welding part 21 is arranged close to one side of the welding port 31 away from the hinged end of the backlight baffle 2, and specifically, the backlight baffle 2 comprises the welding part 21 and the isolation part 22, wherein the length of the isolation part 22 is greater than the length of the welding part 21, the isolation part 22 is arranged across the two ends of the accommodating groove 11, and one end of the welding part 21 extends to be substantially flush with the position of the welding port 31, and the welding part 21 is arranged close to the side of the top block, by arranging the backlight baffle 2 into a special shape, the welding part 21 can be used to separate the welding end 6 from the backlight plate, and at the same time, the welding part 21 can be used to carry the welding end 6; the isolation part 22 crosses the accommodating groove 11 to support the backlight baffle 2, as shown in Figure 3 , by the special shape design of long and short, the space of the short part is more conducive to the bending and storage of the wire row.

[0029] Referring to Figure 1 and Figure 3In the embodiment, the welding partition plate 3 is arranged on the side of the backlight partition plate 2 close to the accommodating groove 11, however, in order to facilitate the folding of the backlight partition plate 2, the welding partition plate 3 is hinged to the jig plate 1. It should be noted that in the actual welding process, the welding gun is easy to touch the welding partition plate 3, which causes the welding partition plate 3 to be scalded or the wire harness pressed at the lower end of the welding partition plate 3 to be scalded. In the embodiment, preferably, the welding partition plate 3 is made of copper foil material, which can prevent the welding partition plate 3 from being scalded by the high-temperature welding gun within a certain period of time, thereby protecting the wire harness pressed at the lower end of the welding partition plate 3 from being scalded by the welding gun.

[0030] Referring to Figure 1 and Figure 4 , the top block 4 can be directly fixed on the jig plate 1, or can be movably arranged on the jig plate 1. The arrangement of the jig plate 1 is fixed, and the head 42 of the top block 4 needs to be inserted into the welding port 31, which means that the head 42 of the top block 4 protrudes into the inside of the accommodating groove 11. Such design is not convenient for taking and placing the backlight plate, and cannot be flexibly adjusted. Preferably, the top block 4 is slidably connected to the jig plate 1. By using the sliding connection, the top block 4 can be slid to a position away from the welding port 31 before the backlight partition plate 2 and the welding partition plate 3 are covered, which can avoid collision with the backlight partition plate 2 and the welding partition plate 3. In addition, it should be particularly noted that the top block 4 is mainly used to top the welding end 6 of the wire harness to the pin 5 of the backlight plate, which not only facilitates the welding operation, but also avoids the situation of scalding by hand. Further, the top block 4 includes a top block body 41 and a head 42, the top block body 41 abuts against one side of the welding partition plate 3, and the head 42 is arranged to extend into the welding port 31.
