[0013] Beneficial Effects

[0014] The utility model provides a circuit board drilling machine calibration and positioning device. Compared with the prior art, it has the following beneficial effects:

[0015] 1. The circuit board drilling machine calibration and positioning device, when it is necessary to drill holes on the circuit board, place the circuit board on the upper end of the placement rack, start the air pump, open the control valve, and allow the air pressure to enter the fixed telescopic rod through the air outlet pipe and the air inlet pipe, so that the fixed telescopic rod begins to push the movable plate to move. After the circuit board and the push plate are pressed against each other, the push plate pushes the piston rod to move, so that the air pressure in the air cylinder begins to increase, and the air pressure is transmitted to the pneumatic telescopic rod through the telescopic hose, so that the pneumatic telescopic rod is extended to push the push rod to move in the push groove, so that the limit block rotates quickly, and the sponge block installed on the limit block squeezes the circuit board, so that the circuit board is fixed in the center position of the placement rack, and the driving mechanism set in the starting punching mechanism is used to move the drilling head to a suitable position, and the punching machine is started, so that the circuit board is more convenient to process and punch holes, so as to avoid errors in the punching positions caused by different fixed positions of the circuit boards when processing different circuit boards.

[0016] 2. The circuit board drilling machine is calibrated and positioned.

As a result, the punching machine can blow the debris generated by punching into the recycling box during the processing of the circuit board, thereby keeping the placement board clean and tidy and making the collection of debris more convenient.

After the circuit board and the push plate 318 are pressed against each other, the push plate 318 pushes the piston rod 308 to move, so that the air pressure in the air cylinder 309 begins to increase, and the air pressure is transmitted to the pneumatic telescopic rod 311 through the telescopic hose 310. The pneumatic telescopic rod 311 is extended to push the push rod 316 to move in the push groove 317, so that the limiter rotates quickly, and the sponge block 315 installed on the limit block 314 squeezes the circuit board, so that the circuit board is fixed in the center position of the placement rack 201, and the driving mechanism set in the starting punching mechanism is used to move the drilling head 217 to a suitable position, and the punching machine 216 is started, so that the circuit board is more convenient to process and punch, thereby avoiding errors in the punching position due to different fixed positions of the circuit boards when processing different circuit boards.

[0031] When the air pump 301 causes the fixed telescopic rod 306 to push the movable plate 307 to squeeze the fixed circuit board, the fixed telescopic rod 306 no longer takes in air, and the air pressure in the air outlet pipe 302 at the output end of the air pump 301 is discharged through the air outlet plate 303, so that the punching machine 216 can blow the debris generated by punching into the recycling box 212 during the processing of the circuit board, thereby keeping the placement board clean and tidy, making the collection of debris more convenient.
