The invention discloses a stretchable rod dust-proofing device of a circuit board edge grinding machine. The stretchable rod dust-proofing device comprises a box body, a groove is formed in the centerof the interior of the box body, a conveying belt is arranged at the bottom end of the groove, edge grinding devices are arranged on the two sides of the top of the conveying belt, the circuit boardis arranged in the center of the top of the conveying belt, a rubber plate is arranged at the top of the circuit board, and stretchable rods are arranged at the top of the rubber plate. According to the stretchable rod dust-proofing device, steel wires drive sliding blocks to move, the sliding blocks drive second connecting rods to deflect towards the side of the stretchable rods, the second connecting rods drive third connecting rods to deflect towards the side far away from the stretchable rods, air inside rubber hoses is discharged through notches of air outlet pipes, rotating gears on theouter sides of rotating rings are fixedly connected with a fixing plate through fixing rods, and spiral springs are arranged inside fixing blocks. The stretchable rod dust-proofing device has the advantages that dust can be prevented from being adsorbed onto the stretchable rods, and the dust on the fixing plate and the stretchable rods can be blown away.
Description
technical field [0001] The invention relates to the technical field of circuit boards, in particular to a dust-proof device for a telescopic rod of a circuit board edging machine. Background technique [0002] The Chinese name of the PCB board is printed circuit board, which is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. Because it is made by electronic printing, it is called "printing". Circuit board, before processing the circuit board, it is necessary to cut and grind the whole substrate. When cutting and edging the PCB board, it is necessary to fix the PCB substrate. In the existing processing equipment, the upper platen is used to clamp PCB substrates are processed. [0003] The clamping device usually uses a telescopic rod, through which the fixed block is attached to the circuit board to be processed to ensure stability, and then it can be processed, but due to grinding ...
