[0024] In this embodiment, the cylinder 4 can push the sliding frame 5 to slide on the fixed frame 2 and the first guide rod 3, so as to adjust the distance between the two groups of cylinder jaws 11. The motor 8 drives the screw rod 9 to rotate, so that the two cylinder jaws 11 in the same group can slide on the second guide rod 7 to adjust the distance between the two. The circuit board can be clamped and fixed by the cylinder jaws 11, so as to achieve clamping and fixing of circuit boards of different sizes, improve the versatility of the device, save labor costs, and improve overall work efficiency and precision.

[0025] Example 2

[0026] like Figure 1-Figure 4 As shown, a funnel 12 is provided at the bottom of the workbench 1, a fan 13 is installed on one side of the funnel 12, a fixed frame 14 is provided at the bottom of the funnel 12, a collecting box 15 is movably installed inside the fixed frame 14, a handle 16 is provided on one side of the collecting box 15, a stabilizing component includes four fixing rods 23, a top cover 24 is fixedly connected to the top of the fixing rods 23, a punching component includes an electric cylinder 25, the electric cylinder 25 is provided on the top of the top cover 24, and the output end of the electric cylinder 25 movably penetrates the top cover 24. The cover 24 is connected to a pressure plate 26, a plurality of punches 27 are provided at the bottom of the pressure plate 26, a plurality of dampers 17 are provided at the top of the fixed frame 2, a spring 18 is sleeved on the outer side of the damper 17, a placement frame 19 is installed on the top of the damper 17, a discharge pipe 20 is fixedly connected to the bottom of the placement frame 19, two sets of rebound hinges 21 are symmetrically provided on both sides of the inside of the discharge pipe 20, one end of the rebound hinge 21 is connected to a baffle 22, and one end of the discharge pipe 20 is movable through the fixed frame 2 and the workbench 1.

[0027] In this embodiment, suction can be generated by the operation of the fan 13 to suck the debris and dust generated by punching into the funnel 12. When the fan 13 is turned off, the debris and dust will be affected by the gravitational potential energy and fall into the collection box 15. At this time, the handle 16 can be grasped and pulled to pull the collection box 15 out of the fixed frame 14 to clean the debris and dust, thereby reducing the difficulty of manual cleaning, saving labor and time costs, improving work efficiency, and keeping the equipment tidy. The fixing rod 23 and the top cover 24 can maintain the stability of the electric cylinder 25 during operation. The electric cylinder 25 is used to push the pressure plate 26 and the punch needle 27 downward to punch the circuit board. At this time, due to the expansion and contraction rebound of the damper 17 and the spring 18 Due to the influence of the characteristics, the placement rack 19 will provide support for the circuit board, while reducing the vibration caused by punching and improving the stability during punching. When the punch needle 27 completely penetrates the circuit board, under the influence of the downward pressure, the rebound hinge 21 will drive the baffle 22 to rotate and open, so that the debris and dust accumulated above the baffle 22 fall from the discharge pipe 20, thereby preventing the debris and dust from bursting or escaping during punching, thereby keeping the punching machine clean and preventing dust from escaping and causing air pollution. Among them, the rebound hinge 21 is a mechanical device used to connect two solids and allow relative rotation and rapid reset between the two. Its application range is relatively wide, and the devices used are well known to those skilled in the art, so they will not be elaborated in this article.

[0028] The working principle of this embodiment is as follows: when in use, first place the circuit board on the placement rack 19, start the two cylinders 4, push the two sliding racks 5 close together, then start the motor 8 to drive the screw rod 9 to rotate, adjust the position of the cylinder clamp 11, and then when the cylinder clamp 11 moves to the appropriate position, the circuit board can be clamped and fixed, and then the electric cylinder 25 is started to push the pressure plate 26 and the punch needle 27 down to punch the circuit board. At this time, the fan 13 is started. When the punch needle 27 completely penetrates the circuit board, the baffle 22 will be pushed open, so that the debris and dust generated by the punching are affected by the suction of the fan 13 and quickly enter the funnel 12 from the discharge pipe 20. Finally, when the punching is completed, turn off the fan 13, the suction disappears, and the debris and dust are affected by the gravitational potential energy and fall into the collection box 15. At this time, grasp and pull the handle 16 to pull the collection box 15 out of the fixed frame 14, so that the debris and dust can be cleaned, thereby completing the use of the fully automatic punching machine for circuit board production.
