[0031] The dust collection unit 200 includes a dust collection box 201, one side of which is fixedly connected to the outer surface of the base 101, a vacuum pump 202 is fixedly connected to the upper surface of the dust collection box 201, a dust collection head 204 is fixedly connected to the input end of the vacuum pump 202, a collection box 203 is slidably connected to the inside of the dust collection box 201, and a handle 205 is fixedly connected to the front outer surface of the collection box 203. The punching table assembly 109 is arranged on the upper surface of the dust collection head 204, and the height of the punching table assembly 109 is consistent with the baffle 108. The cylinder 105 is used to drive the puncher 106 to move up and down to achieve high-precision punching of the door outer panel. The adjustment guide rail 103 allows the position of the puncher 106 to be accurately adjusted to ensure the accuracy of the punching position. During the punching process, the generated metal chips and dust will be immediately sucked away by the dust collection head 204, and then transferred to the collection box 203 in the dust collection box 201 for collection. The vacuum pump 202 provides the necessary suction force to ensure the dust collection effect, and can effectively collect all metal chips and dust generated during the processing, reduce pollution in the workplace and improve the cleanliness of the working environment.

The setting of the electric guide rail 109a and the adjustment guide rail 103 can improve the flexibility of punching, facilitate automatic positioning, and improve the convenience of use. The scraps left by punching will fall into the inside of the groove 107, and then the vacuum pump 202 is started to collect the scraps into the inside of the collection box 203 through the dust collector head 204, so as to realize the convenient collection and treatment of waste materials.
