Technical Field

[0001] This utility model relates to the field of infrared repair technology, specifically to a positioning device suitable for PCBA circuit board repair. Background Technology

[0002] PCBA, or Printed Circuit Board Assembly, refers to an assembly technology that mounts electronic components on the surface of a printed circuit board and then connects these electronic components with other components to form a circuit system.

[0003] Because PCBA circuit boards are relatively expensive, they are usually not discarded when damaged or malfunctioning, but rather need to be repaired to prevent waste of resources. However, PCBA circuit boards generally require the removal of the process edges during repair, which makes it difficult to fix them in place, affecting the convenience of operation for staff and further impacting the repair efficiency. Utility Model Content

[0004] In view of the problems existing in the rework of existing PCBA circuit boards, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a positioning device suitable for PCBA circuit board rework, which solves the problem that PCBA circuit boards are generally difficult to fix during the rework process, thus affecting the convenience of operation for workers and further affecting the rework efficiency of PCBA circuit boards.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A positioning device suitable for PCBA circuit board rework includes a first slide rail and a second slide rail. Each of the first and second slide rails has a groove on one side. Two sliders are slidably disposed inside each of the two grooves. A positioning block is fixedly connected to one side of each slider. Each positioning block has a mounting hole at one end, and a pin is fixedly connected inside each mounting hole. A fixing mechanism is provided on one side of each slider, and each slider is fixedly connected to the inside of the groove through a corresponding fixing mechanism. An adjustment mechanism is provided between the first and second slide rails, allowing both the first and second slide rails to move via the adjustment mechanism.

[0008] Preferably, the fixing mechanism includes multiple screws and multiple nuts, each screw is fixedly connected to one side of the corresponding slider, one end of each screw passes through one side of the corresponding slide groove, and each nut is threaded onto the wall of the corresponding screw.

[0009] Preferably, the adjusting mechanism includes two sleeves, two lead screws, two knobs, and two circular plates. The two sleeves are respectively fixedly connected to one side of the first slide rail, the two lead screws are respectively fixedly connected to one side of the second slide rail, the two lead screws are respectively inserted into the interior of the corresponding sleeves, the two knobs are respectively rotatably connected to the outer surface of the sleeves, the two circular plates are respectively fixedly connected to one side of the corresponding knobs, and each of the two circular plates has an internal thread hole matching the lead screw on one side. The two circular plates are respectively threaded onto the rod wall of the corresponding lead screw through the corresponding internal thread hole.

[0010] Preferably, each of the two grooves has a strip-shaped hole on one side, and the two strip-shaped holes are respectively matched with the corresponding screws.

[0011] Preferably, each of the positioning blocks has a placement platform on its upper surface.

[0012] Preferably, each of the placement platforms has a placement slot on one side.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model uses pins set on the lower surface of each positioning block. When the side of the PCBA circuit board has holes, each positioning block can be moved, and then each pin is inserted into the corresponding hole, thereby fixing the PCBA circuit board. If the PCBA circuit board does not have holes, it can be placed on the upper surface of each positioning block, and then the first slide rail and the second slide rail can be moved to move each positioning block, thereby clamping and fixing the PCBA circuit board.

[0015] 2. In this utility model, by rotating each nut and separating it from the first or second slide rail, each slider can be moved. When the slider moves the positioning block to the designated position, each nut is tightened and tightly fitted to the first or second slide rail, so that each slider can be fixed after movement.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a positioning device suitable for PCBA circuit board rework.

[0024] This utility model provides, for example Figure 1-3 The positioning device shown is suitable for PCBA circuit board rework and includes a first slide rail 1 and a second slide rail 2. A slide groove is provided on one side of both the first slide rail 1 and the second slide rail 2. Two sliders 3 are slidably arranged inside the two slide grooves. A positioning block 4 is fixedly connected to one side of each slider 3. A mounting hole is provided at one end of each positioning block 4. A pin 5 is fixedly connected inside each mounting hole. A fixing mechanism is provided on one side of each slider 3. Each slider 3 is fixedly connected to the inside of the slide groove by a corresponding fixing mechanism. An adjustment mechanism is provided between the first slide rail 1 and the second slide rail 2. Both the first slide rail 1 and the second slide rail 2 can move through the adjustment mechanism.

[0025] When the PCBA circuit board has holes on its side, each positioning block 4 can be moved, and then each pin 5 can be inserted into the corresponding hole to fix the PCBA circuit board. If the PCBA circuit board does not have holes, it can be placed on the upper surface of each positioning block 4, and then the first slide rail 1 and the second slide rail 2 can be moved to move each positioning block 4, thereby clamping and fixing the PCBA circuit board.

[0026] In order to ensure that each slider 3 can be fixed after movement, such as Figure 1-2 As shown, the fixing mechanism includes multiple screws 6 and multiple nuts 7. Each screw 6 is fixedly connected to one side of the corresponding slider 3, and one end of each screw 6 passes through one side of the corresponding slide groove. Each nut 7 is threaded onto the rod wall of the corresponding screw 6.

[0027] Rotate each nut 7 to separate it from the first slide rail 1 or the second slide rail 2, and then each slider 3 can be moved. When the slider 3 moves the positioning block 4 to the designated position, tighten each nut 7 and make it fit tightly against the first slide rail 1 or the second slide rail 2, so that each slider 3 can be fixed after movement.

[0028] To make the distance between the first slide rail 1 and the second slide rail 2 adjustable, such as Figure 1-2 As shown, the adjustment mechanism includes two sleeves 8, two lead screws 9, two knobs 10, and two circular plates 11. The two sleeves 8 are fixedly connected to one side of the first slide rail 1, and the two lead screws 9 are fixedly connected to one side of the second slide rail 2. The two lead screws 9 are inserted into the interior of the corresponding sleeves 8. The two knobs 10 are rotatably connected to the outer surface of the sleeves 8. The two circular plates 11 are fixedly connected to one side of the corresponding knobs 10. One side of each of the two circular plates 11 is provided with an internal thread hole that matches the lead screw 9. The two circular plates 11 are threaded onto the rod wall of the corresponding lead screw 9 through the corresponding internal thread hole.

[0029] Rotating the two knobs 10 causes the two circular plates 11 to rotate, which in turn allows each lead screw 9 to move into the corresponding sleeve 8, thereby changing the distance between the first slide rail 1 and the second slide rail 2. This makes the device suitable for PCBA circuit boards of different specifications.

[0030] In order for screw 6 to move, such as Figure 1 As shown, each of the two grooves has a strip-shaped hole on one side, and the two strip-shaped holes are respectively matched with the corresponding screws 6.

[0031] The two slotted holes facilitate the movement of the two screws 6.

[0032] To facilitate the placement of PCBA circuit boards, such as Figure 1-3 As shown, each positioning block 4 has a placement platform on its upper surface, and each placement platform has a placement slot on one side.

[0033] Each placement platform facilitates the placement of PCBA circuit boards, while each placement slot facilitates the placement of components on the sides of the PCBA circuit boards.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
