Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing devices, in particular to a punching platform for circuit board processing. Background Art

[0002] In the production process of printed circuit boards, it is necessary to drill holes. Some of the holes are used to make through holes for copper plating of various layers of circuits, and some are used to make positioning holes, etc. The current drilling method is very simple, that is, put the printed circuit board on the support seat, and then start the motor, so that the drill bit connected to the motor will drill the printed circuit board downward.

[0003] For example, the punching platform for circuit board processing with application number 201711447534.9 reduces environmental pollution, effectively supports the bottom of the circuit board, ensures processing quality, and can fix the circuit board at the center of the drilling template with high positioning accuracy. However, when the drill is drilling, the upper surface of the circuit board will generate a lot of waste chips and dust under the high-speed rotation of the drill bit. It is difficult for this device to reduce the chips and dust generated in this case.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a punching platform for circuit board processing is proposed. Utility Model Content

[0013] 1. The utility model is provided with a base, a slide, a slide rod, a slide seat, an electric telescopic rod, a punching device, a dustproof mechanism, a threaded seat, a dustproof cylinder, a slide cylinder, and a dust collector. When the device is positioned and punched, the slide rod on the slide can be slid to determine the longitudinal position, and the slide seat on the slide rod can be slid to determine the lateral position. The electric telescopic rod is extended, and the punching device can drive the drill bit to perform a punching operation.

This design can effectively reduce the splashing of debris during drilling.

[0014] 2. The utility model adopts the arrangement of a bidirectional screw, a hand wheel, a screw bearing, a ball nut seat, a fixing rod, and a clamping plate. When clamping a circuit board, the bidirectional screw is rotated by the hand wheel to drive the two ball nut seats to move closer to or away from each other, thereby driving the two clamping plates to clamp circuit boards of different sizes through the fixing rod.
