[0097] Working principle: when in use, first start the motor 15, the output shaft of the motor 15 will drive the transmission wheel 23 to rotate, the rotation of the transmission wheel 23 will drive the conveyor belt 4 to transmit, the transmission of the conveyor belt 4 will drive the transmission wheel 2 to rotate, the transmission of the conveyor belt 4 will drive the circuit board on the conveyor belt 4 to move, during the movement, the two guide plates 7 can correct the position of the circuit board to ensure that the circuit board can move horizontally between the two clamping blocks 26, when the sensor 29 senses the circuit board, the sensor 29 will send a signal to the driver 30, the driver 30 will control the motor 15 to stop the motor 15, so that the circuit board will stop between the two clamping blocks 26, then the driver 30 will send a signal to the two electric push rods 28 to start the two electric push rods 28, the output shafts of the two electric push rods 28 will respectively drive the two clamping blocks 26 to move, so that the two clamping blocks 26 are close to each other, the two clamping blocks 26 are close to each other to clamp the circuit board, and at the same time, under the action of the two rubber pads 27, it can be ensured that the circuit board will not be damaged during the clamping process;

[0098] Subsequently, the driver 30 will drive the motor 2 11 and the electric slide rail 14 respectively, and the output shaft of the motor 2 11 will drive the threaded rod 10 to rotate. Under the action of the thread, the rotation of the threaded rod 10 will drive the sliding block 9 to move left and right, and the left and right movement of the sliding block 9 will drive the electric slide rail 14 to move left and right, and the left and right movement of the electric slide rail 14 will drive the slider 15 to move left and right, and the left and right movement of the slider 15 will drive the hydraulic cylinder 16 to move left and right. At the same time, the electric slide rail 14 will also drive the slider 15 to move forward and backward, and the forward and backward movement of the slider 15 will drive the hydraulic cylinder 16 to move forward and backward until the hydraulic cylinder 16 moves to the position on the circuit board that needs to be polished and stops, ensuring that it can adapt to holes in different positions;

[0099] Then the driver 30 will drive the hydraulic cylinder 16 and the motor three 17, the output shaft of the motor three 17 will drive the grinding block one 18 and the fan blade 25 to rotate, the rotation of the grinding block one 18 will drive the grinding block two 31 to rotate, the rotation of the grinding block two 31 will drive the grinding block three 22 to rotate, and at the same time the output shaft of the hydraulic cylinder 16 will drive the motor three 17 to move downward, the downward movement of the motor three 17 will drive the grinding blocks one 18 and the grinding blocks two 31 and the grinding blocks three 22 to move downward, the driver 30 can control the height of the motor three 17 to descend according to the size of the holes in the circuit board, when the holes on the circuit board are small, the smaller holes can be polished and deburred by the grinding block three 22, and when the holes on the circuit board are When the hole is of normal size, the grinding block 2 31 can be used to grind and deburr the hole of normal size. When the hole on the circuit board is large, the grinding block 18 can be used to grind and deburr the larger hole. When the grinding block 18 is in use, the bottom end of the grinding block 3 22 will be against the conveyor belt 4 so as to move up and down. At the same time, the upward movement of the grinding block 3 22 will squeeze the spring 23 to shrink. At the same time, the spring 23 will squeeze the grinding block 2 31 to move upward. The upward movement of the grinding block 2 31 will squeeze the spring 1 20 to shrink, thereby ensuring that the grinding block 18 can operate normally and ensuring that the appropriate grinding block size can be selected according to the size of the hole on the circuit board, thereby improving the overall grinding and deburring efficiency.

[0100] At the same time, the rotation of the fan blades 25 can draw outside air into the protective net 24 and blow it toward the circuit board, ensuring that during the process of grinding the circuit board, the debris generated during grinding can be blown out, ensuring that no debris remains on the surface of the circuit board after grinding. After grinding is completed, the driver 30 will drive the two electric push rods 28 to release the clamping of the two clamping blocks 26 on the circuit board, and then the driver 30 will start the motor 5 again to allow the conveyor belt 4 to continue to drive, thereby grinding the burrs of the holes on the next circuit board, thereby realizing fully automatic grinding of the burrs of the holes on the circuit board.
