Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to an automatic drilling and positioning device for circuit boards. Background Technology
[0002] In the process of circuit board production, various positioning and mounting holes need to be drilled on the circuit boards. Existing positioning and drilling devices mostly use mechanical clamping to fix the circuit board first, and then drill holes. Mechanical clamping is prone to local deformation and edge damage of the board, and has poor adaptability to flexible boards and irregularly shaped boards, and is difficult to absorb vibrations during drilling. Therefore, in view of the above situation, there is an urgent need to develop an automatic drilling and positioning device for circuit boards that can quickly and accurately position the circuit board with right-angle positioning blocks, and whose flexible fixing mechanism uses elastic clamping airbags to distribute force evenly with surface contact, protecting vulnerable boards, adapting to irregularly shaped boards, and buffering vibrations, in order to overcome the shortcomings of current practical applications and meet current needs.

This achieves rapid and accurate positioning of the circuit board. Then, the solenoid valve 305 is opened, allowing the circuit board to pass under the elastic clamping airbag 302. Next, the high-pressure bidirectional air pump 303 is activated to inflate the elastic clamping airbag 302. As the airbag expands, it gradually presses the circuit board onto the worktable 1. After inflation, the solenoid valve 305 is closed. This ensures that the air pressure inside the elastic clamping airbag 302 remains stable. The elastic clamping airbag 302 can achieve uniform force through surface contact, which can effectively protect vulnerable materials such as flexible boards and ultra-thin boards, and avoid edge damage and local deformation. Its elastic characteristics can adapt to the contour of irregular boards and can also buffer drilling vibration. Then, the PLC controller 10 controls the left and right displacement mechanism 4, the up and down displacement mechanism 6, and the front and back displacement mechanism 8 to drive the drilling mechanism 9 to move in the left and right, up and down, and front and back directions to accurately adjust the position.
