[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1 and Figure 3 The utility model provides a technical solution: a PCB production transfer fixture, including a bottom plate 1, on which two rotating plates 3 placed opposite to each other are arranged, the rotating plate 3 is a frame with an opening on the top surface and the opposite surface, the lower end of the rotating plate 3 on the outer side is hinged to the bottom plate 1 through a hinge shaft 2, the rotating plate 3 can rotate around the hinge shaft 2, and a clamping device that can stably place the PCB board is arranged in the rotating plate 3, the rotating plate 3 is rotated upward around the hinge shaft 2, so that the distance between the upper ends of the two rotating plates 3 is increased, so that the PCB board is conveniently placed between the rotating plates 3, and then the rotating plate 3 is rotated downward, the distance between the rotating plates 3 is reduced, and the squeezing clamping device clamps the PCB board to fix it, and when the PCB board needs to be taken out, it is only necessary to rotate the rotating plate 3 upward, the clamping device releases the PCB board, and the PCB board can be taken out.

[0018] The clamping device includes two clamping blocks 5, which are located in the two rotating plates 3. The clamping block 5 is a concave block, and the open sides of the two clamping blocks 5 are placed facing each other. A compression spring 4 is arranged between the clamping block 5 and the rotating plate 3. The spring 4 is in a compressed state and has elastic force to restore the original state. One end of the spring 4 is connected to the back of the clamping block 5, and the other end is connected to the inner wall of the rotating plate 3 which is parallel to the back of the clamping block 5. When the rotating plate 3 is opened, the PCB board is placed between the clamping blocks 5, the rotating plate 3 is closed, and the clamping block 5 contracts toward the middle, and the PCB board is clamped by the action of the compression spring 4.

[0019] Two parallel clamps 6 are arranged in the clamp block 5, and the clamps 6 are placed perpendicular to the bottom surface of the clamp block 5. A connecting rod 7 is arranged on the outer wall of the clamp plate 6, and the connecting rod 7 is slidably installed on the side wall of the clamp block 5. An inclined plate 8 is arranged on the bottom plate 1, and the inclined plate 8 is located on both sides of the rotating plate 3, and the lower end of the inclined plate 8 is closer to the rotating plate 3 than the upper end. One end of the connecting rod 7 extends out of the clamp block 5 and contacts with the inclined plate 8. A tension spring 9 is arranged between the clamp plate 6 and the clamp block 5, and the two ends of the tension spring 9 are respectively connected to the clamp plate 6 and the clamp block 5. The tension spring 9 is in a stretched state and has the elastic force to restore the original state. When the rotating plate 3 rotates downward, the connecting rod 7, under the action of the inclined surface of the inclined plate 8, causes the two clamps 6 to move toward each other, thereby clamping the PCB board placed therebetween.

[0020] The side wall of the clamping plate 6 is provided with a sponge pad 10. The sponge pad 10 can not only prevent the PCB from sliding and improve stability, but also prevent the PCB from being damaged.

[0021] A universal wheel 13 is provided at the lower end of the bottom plate 1, and a handle 12 is provided on the outer side wall of the rotating plate 3. The universal wheel 13 is provided to facilitate the transportation of the PCB board, and the handle 12 is provided to facilitate the rotation of the rotating plate 3.

[0022] A convex plate 11 is provided on the side wall of the lower end of the rotating plate 3. By providing the convex plate 11, when the PCB board is placed between the rotating plates 3, the lower end of the PCB board contacts the convex plate 11, and the PCB board is pressed downward, so that the convex plate 11 can drive the rotating plate 3 to rotate downward, and the rotating plate 3 automatically closes to clamp and fix the PCB board.

[0023] In the utility model, the working steps of the device are as follows: the rotating plate 3 is rotated upward around the hinge shaft 2 to increase the distance between the openings at the upper ends of the two rotating plates 3, the PCB board is placed between the clamping plates 6, and the PCB board is pressed downward to make the convex plate 11 drive the rotating plate 3 to rotate downward, the clamping block 5 shrinks toward the middle, and the PCB board is clamped left and right by the action of the compression spring 4. When the rotating plate 3 is rotated downward, the connecting rod 7 moves the two clamping plates 6 toward each other under the inclined force of the inclined plate 8 to clamp the PCB board front and back. When the PCB board needs to be taken out, it is only necessary to rotate the rotating plate 3 upward through the handle 12, the distance between the upper ends of the clamping blocks 5 increases, the elasticity of the compression spring 4 decreases, and the clamping plates 6 are under the action of the tension spring 9. The distance between the clamping plates 6 increases, the PCB board is loosened, and the PCB board can be taken out.
