The bolt 27 is threadedly connected with an adjusting clamp plate 26, and the two side walls of the adjusting clamp plate 26 are slidably connected to the inner wall of the fixed frame 25. A heat dissipation structure 3 is installed inside the accommodating groove 11 on one side of the fixed frame 25. The heat dissipation structure 3 includes gears 32 that are meshed with each other, and a rotating rod 33 is fixedly sleeved on the inner wall of the gear 32. A fan 34 is coaxially connected to one end of the rotating rod 33. The servo motor 31 drives a number of gears 32 that are meshed with each other to rotate, so that the rotating rod 33 coaxially sleeved on the inner wall of the gear 32 rotates, which is convenient for the use of the fan 34 and cooperates with the vent 13 to perform cooling treatment during the process of welding circuit boards with the packaging laser, thereby ensuring the welding quality and speed of the circuit boards.

[0029] In this embodiment, the bottom of the receiving groove 11 is symmetrically provided with sliding grooves 12, and the protrusions at both ends of the sliding block 23 are slidably connected in the sliding grooves 12, which is convenient for normal use of the structure.

[0030] Then, the outer wall of the bidirectional threaded rod 21 is threadedly connected to the bottom of one end of the sliding block 23, and the other end of the sliding block 23 is slidably connected to the sliding rod 22, which facilitates the normal use of the structure.

[0036] Working principle: When using the packaged laser to weld the pressure plate, the user first uses the handle to rotate the bidirectional threaded rod 21, which drives the two sliding blocks 23 to move toward each other, and uses the adjusting bolt 27 to adjust the distance between the adjusting clamp 26 and the fixed frame 25 to clamp the circuit board. The packaged laser performs circuit board welding, and then turns on the servo motor 31. The servo motor 31 drives a number of rotating rods 33 with the same number as the gears 32 to rotate through gears 32 that are meshed in pairs, that is, the fan 34 blows air and cooperates with the vent 13 to dissipate heat.
