[0031] Please see Figures 1-6 As shown, a PCB board processing fixture includes:

[0032] A fixed base 1, wherein a support frame 2 is fixedly connected to the side of the fixed base 1;

[0033] The movable adjustment module 3 is disposed on the upper surface of the fixed base 1, and the movable adjustment module 3 is used to adjust the spacing of the clamp module 4;

[0034] The clamp module 4 is fixedly installed at the upper end of the movable adjustment module 3. The clamp module 4 is provided with a clamping part 403, which can be moved and adjusted. The clamping part 403 is used to adjust the clamping point position during clamping.

[0035] Through the above technical solution, the clamping part 403 can be set to flexibly adjust the clamping point position during clamping, so that it can be adjusted according to different PCB boards to avoid components, pads, traces or other areas that need to be processed and inspected on the PCB. No additional clamping is required, making it flexible and convenient to use and avoiding interference during processing. It is especially suitable for processing different types of PCB boards.

[0036] The fixed base 1 has an internal cavity. The support frame 2 includes a movable plate frame 301 and a fixed plate frame 303. The fixed plate frame 303 is fixedly mounted on the upper surface of the fixed base 1. The movable plate frame 301 is mounted on the upper surface of the fixed base 1 and slides with the fixed base 1. The fixed base 1 has an adjustment part inside, which is used to adjust the position of the movable plate frame 301. Through the above technical solution, by adjusting the distance between the movable plate frame 301 and the fixed plate frame 303, PCB boards of different sizes can be processed within a certain range.

[0037] The adjustment unit includes a movable slider 302, an adjustment screw 304, and an adjustment knob 305. The movable slider 302 is disposed in the inner cavity of the fixed base 1 and is slidably engaged with the fixed base 1. The movable slider 302 is fixedly connected to the movable plate frame 301. The adjustment screw 304 is rotatably connected to the inner wall of the fixed base 1. The adjustment screw 304 passes through the movable slider 302 and is threadedly engaged with the movable slider 302. The adjustment knob 305 is fixedly connected to one end of the adjustment screw 304. Through this technical solution, rotating the adjustment knob 305 can drive the adjustment screw 304 to rotate, and then the rotation of the adjustment screw 304 can drive the movable slider 302 to move. Thus, the movement of the movable slider 302 can drive the movement of the movable plate frame 301, thereby realizing the function of adjusting the spacing.

[0038] Preferably, the movable slider 302 is located in the inner cavity of the fixed base 1, and its top surface is fixedly connected to the bottom of the movable plate frame 301 through a connector, which is a bolt or an integrally formed connecting column;

[0039] The adjustment knob 305 is located on the outside of the end face of the fixed base 1, making it easy for the operator to rotate;

[0040] The clamping module 4 includes a U-shaped fixing block 401, a rotating seat 402, and a clamping part 403. There are two rotating seats 402, which are respectively mounted on the movable plate frame 301 and the fixed plate frame 303 and rotate in cooperation. A U-shaped fixing block 401 is fixedly connected to one end of the rotating seat 402, and the two U-shaped fixing blocks 401 are arranged in a mirror image.

[0041] Both the fixed plate frame 303 and the movable plate frame 301 are threaded with locking bolts 404 at their top positions. With this technical solution, when in use, the rotating seat 402 can be rotated by loosening the locking bolts 404, which in turn allows the PCB board that is clamped and fixed to rotate, thereby achieving the function of adjusting the angle. After tightening, the rotating seat 402 can be locked to achieve the function of fixing the angle.

[0042] A sliding groove is provided on the side wall of the U-shaped fixing block 401, and a pressure plate 405 is slidably connected to the sliding groove of the U-shaped fixing block 401. A clamping part 403 is fixedly connected to both the side wall of the pressure plate 405 and the bottom side wall of the U-shaped fixing block 401.

[0043] A screw 406 is rotatably connected to the upper surface of the pressure plate 405. The screw 406 passes through the U-shaped fixing block 401 and is threadedly engaged with the U-shaped fixing block 401. A rotating part 407 is fixedly connected to the top end of the screw 406. Through this technical solution, rotating the rotating part 407 can drive the screw 406 to rotate, thereby driving the pressure plate 405 to move through the rotation of the screw 406, which in turn drives the clamping part 403 to perform a clamping action, clamping and fixing the side of the PCB board.

[0044] Preferably, the top wall of the U-shaped fixing block 401 has a threaded through hole in the middle; the lower end of the screw 406 is rotatably connected to the center of the upper surface of the pressure plate 405 through a bearing; the threaded section in the middle of the screw 406 passes through the threaded through hole and is threadedly engaged with it; the upper end of the screw 406 is fixedly connected to the rotating part 407.

[0045] The clamping part 403 includes a rectangular crossbar 4031, a clamping claw 4032 and a locking screw 4033, and a sliding groove is provided on the rectangular crossbar 4031.

[0046] The clamping claws 4032 are provided in a plurality of manner, and each of the clamping claws 4032 has a sliding groove on one side that engages with the rectangular crossbar 4031. The clamping claws 4032 are disposed on the rectangular crossbar 4031 and slide in engagement with the rectangular crossbar 4031.

[0047] The side wall of the clamping claw 4032 is threaded with a locking screw 4033. Through this technical solution, by moving the clamping claw 4032, the position and spacing of several clamping claws 4032 can be adjusted, thereby adjusting according to the structure of the object being clamped, so that the clamping claw 4032 avoids electronic components or other areas that need to be processed and inspected on the PCB board. After the clamping claw 4032 is adjusted, it can be locked and fixed by tightening the locking screw 4033.

[0048] Preferably, each gripper 4032 has a threaded hole on its top or side, into which the locking screw 4033 is screwed; when the locking screw 4033 is tightened, its end presses downward against the upper surface of the rectangular crossbar 4031, thereby locking the gripper 4032 in the current position.

[0049] In practical use:

[0050] When it is necessary to clamp PCB boards of different widths, rotate the adjustment knob 305 to drive the adjustment screw 304 to rotate, which in turn drives the movable slider 302 and the movable board frame 301 fixed thereto to slide along the fixed base 1, thereby increasing or decreasing the distance between the two clamping modules 4.

[0051] When it is necessary to adjust the horizontal angle of the PCB board, loosen the locking bolts 404 on the fixed board frame 303 and the movable board frame 301, manually rotate the rotating seat 402 and the U-shaped fixing block 401 connected thereto, thereby driving the PCB board to be clamped to rotate to the required angle, and then tighten the locking bolts 404 to fix it.

[0052] When it is necessary to avoid a specific area of ​​the PCB board, first loosen the locking screw 4033 on the clamping claw 4032, and then slide each clamping claw 4032 along the rectangular crossbar 4031 to make its clamping point avoid the component, pad or trace area; after adjusting it into place, tighten the locking screw 4033 to fix each clamping claw 4032.

[0053] The PCB board is placed between two opposing clamping claws 4032. After adjusting the position, the rotating part 407 is rotated, and the screw 406 drives the pressure plate 405 and the clamping claws 4032 on it to move downward. Together with the clamping claws 4032 on the bottom side wall of the U-shaped fixing block 401, the edges of the PCB board are clamped and fixed. The clamping claws 4032 can move and be fixed independently on the rectangular crossbar 4031, realizing flexible positioning and distribution of clamping points. This ensures that when the PCB board is actually clamped, it can actively avoid electronic components, pads, traces or other processing and inspection areas on it, effectively preventing processing interference.
