The bottom of the fixing block 7 is fixedly connected to the top of the bottom plate 1. An adaptation mechanism 8 is arranged on the top of the bottom plate 1.

[0023] Referring to Figure 3 , the adaptation mechanism 8 includes long plates 81. The number of long plates 81 is two. The front side and the rear side of the long plates 81 are rotatably connected to the inside of the fixing block 7 through pin shafts. A long block 82 is fixedly connected to the top inside the long plates 81. A sliding rod 83 is slidably connected to the inside of the long block 82. A connecting block 84 is fixedly sleeved on the surface of the sliding rod 83. A positioning plate 85 is fixedly connected to the inside of the connecting block 84. A guiding rod 86 is fixedly connected to the top of the positioning plate 85. The number of guiding rods 86 is three. A first spring 87 is fixedly sleeved on the surface of the guiding rod 86. One end of the first spring 87 is fixedly connected to the top of the positioning plate 85. The other end of the first spring 87 is fixedly connected to a reinforcing plate 88. The bottom of the reinforcing plate 88 is fixedly connected to the top of the long plate 81.

[0024] As a technical optimization scheme of the present invention, by setting the adaptation mechanism 8, when the pneumatic telescopic rod 5 drives the long plates 81 and the positioning plate 85 to contact the surface of the PCB board 3 in cooperation with the pneumatic telescopic rod 5, the first spring 87 is compressed and pushes the positioning plate 85, the connecting block 84, and the guiding rod 86 to move upward. When the long plates 81 are at a right angle, the rebound of the first spring 87 drives the positioning plate 85, the connecting block 84, and the guiding rod 86 to adapt the size of the top of the PCB board 3, facilitating the positioning of the current PCB board 3 and improving the positioning effect of the PCB board 3.

[0025] Referring to Figure 2 , round blocks 9 are fixedly connected to the four corners of the top of the workbench 2. The round blocks 9 are used in cooperation with the PCB board 3.

[0026] As a technical optimization solution of the present utility model, by providing the round block 9, when the PCB board 3 is placed on the workbench 2, the round block 9 can be inserted into the punched hole of the PCB, so as to further strengthen the fixation of the PCB board 3 during the soldering process and improve the fixation effect on the PCB board 3.

[0027] Reference Figure 4 , a second spring 10 is fixedly connected to the rear side of the long plate 81, and the second spring 10 is used in cooperation with the fixed block 7.

[0028] As a technical optimization solution of the present utility model, by providing the second spring 10, when the long plate 81 is disassembled, the long plate 81 can be pushed to compress the spring, so that the long plate 81 exits from the inside of the front fixed block 7, improving the replacement efficiency of the long plate 81.

[0029] Reference Figure 3 , bumpers 11 are fixedly connected to the bottom of the positioning plates 85, and the bumpers 11 are made of rubber material.

[0030] As a technical optimization solution of the present utility model, by providing the bumpers 11, when the positioning plates 85 contact the PCB board 3, the friction between the positioning plates 85 and the PCB board 3 can be increased through the bumpers 11, improving the fixation effect of the positioning plates 85 on the PCB board 3.

[0031] Reference Figure 5 , round hole grooves 12 are formed on the surface of the reinforcing plate 88, and the round hole grooves 12 are used in cooperation with the guide rods 86.

[0032] As a technical optimization solution of the present utility model, by providing the round hole grooves 12, the guide rods 86 can move towards the top of the reinforcing plate 88, reducing the friction of the guide rods 86 and improving the moving effect of the guide rods 86.

[0033] Reference Figure 4 , a reinforcing block 13 is fixedly connected to the top of the long plate 81 by bolts, and the bottom of the reinforcing block 13 is fixedly connected to the top of the long plate 81 by bolts.

[0034] As a technical optimization solution of the present utility model, by providing the reinforcing block 13, the connection between the long block 82 and the long plate 81 can be strengthened and fixed, improving the use rigidity of the long block 82.

[0035] The working principle and use process of the utility model are as follows: when in use, the PCB board 3 is placed on the top of the workbench 2, and the pneumatic telescopic rod 5 is started. The output end of the pneumatic telescopic rod 5 drives the rotating seat 2 6 to flip around the rotating seat 2 6, and then the rotating seat 2 6 pushes the long plate 81, and the long plate 81 and the positioning plate 85 are flipped toward the position of the PCB board 3 around the fixed block 7. At the same time, the pneumatic telescopic rod 5 is gradually extended, and the pneumatic telescopic rod 5 is tilted toward the position of the PCB board 3 through the rotating seat 1 4 as the center. When the positioning plate 85 contacts the surface of the PCB board 3, the spring 1 87 is squeezed and pushes the positioning plate 85, the connecting block 84, and the guide rod 86 to move upward. When the long plate 81 is at ninety degrees, the rebound of the spring 1 87 drives the positioning plate 85, the connecting block 84, and the guide rod 86 to adapt the size of the top of the PCB board 3, so as to facilitate the positioning of the current PCB board 3.

[0036] In summary, the PCB positioning mechanism, through the coordinated use of the base plate 1, the workbench 2, the PCB board 3, the rotating seat 1 4, the pneumatic telescopic rod 5, the rotating seat 2 6, the fixing block 7 and the adapting mechanism 8, solves the problem that when PCB boards of different sizes are positioned, since most of the positioning components can only be adapted to PCB boards of a specific size range, when positioning a PCB board of a larger size, it is necessary to manually replace the corresponding positioning components, resulting in a poor positioning effect of the PCB board and reducing the positioning efficiency of the PCB board.
