All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1-Figure 4 The utility model provides a technical solution: a positioning mechanism, the positioning mechanism comprising: a bottom plate 1, a vertical plate 2 is arranged on the surface of the bottom plate 1, a support rod 3 is arranged inside the vertical plate 2, a positioning ring 4 is sleeved on the surface of the support rod 3, and a positioning rod 5 is arranged on the side of the vertical plate 2;

[0024] A base 6, a support plate 7 is arranged on the surface of the base 6, a moving screw 8 is arranged inside the support plate 7, and a positioning plate 9 is screwed on the surface of the moving screw 8. A PCB circuit board welding processing tool includes the positioning mechanism;

[0025] When the PCB needs to be positioned during use, one end of the PCB is first inserted into the movable groove 10, and then the movable screw 8 can be rotated to move the positioning plate 9 in the movable groove 10, so that the positioning plate 9 can cooperate with the inner side of the support plate 7 to position the PCB. When the side of the PCB needs to be welded, the positioning ring 4 can be first pulled out from a group of positioning rods 5, and the support plate 7 can be rotated. After being rotated to a suitable angle, the positioning ring 4 is sleeved on the other group of positioning rods 5 to fix them, so that the side of the PCB can be welded conveniently.

[0026] Embodiment 2: Based on Embodiment 1, a movable screw 8 is provided to facilitate positioning and clamping of the PCB circuit board. A movable groove 10 is provided on the surface of the support plate 7. A slide groove 12 is provided on the surface of the movable groove 10. A positioning bearing 11 is provided on the end surface of the slide groove 12. The positioning plate 9 can slide in the movable groove 10 and the slide groove 12. One end of the movable screw 8 is fixedly connected to the inner ring surface of the positioning bearing 11. The movable screw 8 can be rotated to displace the positioning plate 9.

[0027] When in use, one end of the PCB circuit board can be placed in the moving groove 10 to perform preliminary positioning of the PCB circuit board to prevent the PCB circuit board from tipping over. Then, the moving screw 8 can be rotated in cooperation with the positioning bearing 11, so that the positioning plate 9 can be moved in the moving groove 10 and the slide groove 12, and the inner side surface of the support plate 7 and the positioning plate 9 can be conveniently cooperated to clamp and position the two side surfaces of the PCB circuit board, thereby facilitating stability during subsequent welding.

[0028] Embodiment 3: On the basis of embodiment 2, in order to facilitate the inclination angle of the PCB circuit board after positioning, a positioning ring 4 is provided, the vertical plate 2 is fixedly connected to the surface of the bottom plate 1, a hole is provided on the side of the vertical plate 2, a bearing 13 is provided in the hole, one end of the support rod 3 is fixedly connected to the inner ring surface of the bearing 13, a card slot 14 is provided on the side of the support rod 3, a plurality of groups of positioning rods 5 provided on the side of the vertical plate 2 are provided, and the plurality of groups of positioning rods 5 are fixedly connected to the side of the vertical plate 2, the base 6 is fixedly connected to the end face of the support rod 3, a limiting hole 15 is provided on the surface of the positioning ring 4, a damping ring 16 is provided in the limiting hole 15, the limiting hole 15 can be sleeved on the positioning rod 5, a slider 17 is provided on the inner side of the positioning ring 4, the slider 17 can be inserted into the card slot 14, and the slider 17 can be displaced along the card slot 14;

[0029] When the PCB circuit board needs to be tilted after being positioned during use, the positioning ring 4 is first removed, and then the support rod 3 can be used in conjunction with the bearing 13 to rotate the support plate 7. After the rotation angle, the positioning ring 4 can be sleeved on the support rod 3 so that the limiting hole 15 is also sleeved on the positioning rod 5, thereby avoiding the problem of continued rotation of the support plate 7. The setting of the damping ring 16 can increase the friction between the limiting hole 15 and the surface of the positioning rod 5 to avoid the positioning ring 4 from detaching from the support rod 3. The slider 17 cooperates with the setting of the card slot 14 to avoid the problem of rotation of the positioning ring 4.

[0030] In actual use, when it is necessary to position the PCB circuit board, first insert one end of the PCB circuit board into the movable groove 10, and then the movable screw rod 8 can be rotated to make the positioning plate 9 move in the movable groove 10, so that the positioning plate 9 can cooperate with the inner side of the support plate 7 to position the PCB circuit board. When it is necessary to weld the side of the PCB circuit board, first the positioning ring 4 can be pulled out from a group of positioning rods 5, and the support plate 7 can be rotated. After rotating to a suitable angle, the positioning ring 4 is sleeved on the other group of positioning rods 5 to fix it, so that it is convenient to weld the side of the PCB circuit board. This avoids the problem that the general positioning structure is relatively fixed. When it is necessary to weld the side of the PCB circuit board, the PCB circuit board needs to be removed and the tilt angle needs to be re-fixed so that welding can be carried out, which is inconvenient and reduces the welding efficiency.
