[0026] In terms of specific structure, refer to Figure 4 As shown, the first positioning part 210 in this embodiment is a positioning groove provided on the base 200, which allows the first printed circuit board 100 to be placed. The inner wall of the positioning groove is provided with a support platform 211 capable of supporting the first printed circuit board 100. The shape of the positioning groove is adapted to the shape of the first printed circuit board 100 so that when the first printed circuit board 100 is placed in the positioning groove, the first printed circuit board 100 is positioned in the horizontal direction, and the depth of the support platform 211 is used to position the first printed circuit board 100 in the vertical direction.

[0027] refer to Figure 2 and Figure 3 As shown, the positioning unit in this embodiment includes a mounting block 220 fixed on the base 200, and the mounting block 220 is provided with a threaded hole. The positioning unit also includes a positioning rod 221 screwed into the threaded hole. The end face of the positioning rod 221 away from the mounting block 220 constitutes a positioning surface. When the second positioning block 320 slides to abut against the positioning rod 221, it indicates that the second positioning block 320 has slid into place.

[0028] In this embodiment, there are two positioning rods 221, which are respectively installed on two opposite sides of the mounting block 220. One of the two positioning rods 221 is used to position the second positioning block 320, and the other of the two positioning rods 221 is used to position the third positioning block 330 described below. They operate on the same principle and will not be described again here. It should be noted that it is also feasible to provide positioning rods 221 on the second positioning block 320 and the third positioning block 330, and to provide fixing blocks on the base 200 that can abut against the positioning rods 221.

[0030] In this embodiment, the positioning device can simultaneously position the second printed circuit board 110 and the third printed circuit board 120 relative to the first printed circuit board 100, so as to solder and fix the second printed circuit board 110 and the third printed circuit board 120 onto the first printed circuit board 100.

[0033] By setting the above structure, in the positioning device of this embodiment, the second positioning block 320 and the third positioning block 330 can be moved closer or further apart by rotating the threaded rod. That is, rotating the threaded rod can simultaneously complete the positioning of the second positioning block 320 and the third positioning block 330, which is more convenient to use.

[0034] refer to Figure 2 and Figure 3 As shown, in this embodiment, the second positioning part 321 is a second positioning groove provided on the second positioning block 320. The second printed circuit board 110 can be placed into the second positioning groove and fit against the bottom surface of the second positioning groove. By pre-setting the parallelism between the bottom surface of the second positioning groove and the platform surface of the support platform 211, the parallelism between the second printed circuit board 110 and the first printed circuit board 100 can be ensured. The third positioning part 331 is a third positioning groove provided on the third positioning block 330, which has the same principle as the second positioning groove, and will not be described in detail here.

[0035] In this embodiment, guide units are provided between the second positioning block 320 and the base 200, and between the third positioning block 330 and the base 200, respectively, to form a guide for the second positioning block 320 and the third positioning block 330 to slide on the base 200.

[0038] Based on the above structure, the working process of the positioning device in this embodiment is as follows:

[0039] Rotate the threaded rod to move the second positioning block 320 and the third positioning block 330 away from each other, so that the first positioning groove is exposed;

[0040] The first printed circuit board 100 is placed in the first positioning groove;

[0041] Rotate the threaded rod in the opposite direction to bring the second positioning block 320 and the third positioning block 330 closer together until the second positioning block 320 and the third positioning block 330 abut against the corresponding positioning blocks;
