The invention discloses a longitudinal moving type PCB board
grinding device which comprises a base, an X-axis feeding mechanism, a carrying die, a door frame, an air cylinder, a guide rod, a supporting plate, a square
pipe, a first support, a rack, a rotating shaft, a
servo motor, a gear, a second support, a speed adjusting motor and a board
grinding mechanism. A PCB is placed in the carrying die. The air cylinder moves downwards to push a template mechanism to make contact with the PCB. The speed adjusting motor works to drive the board
grinding mechanism to conduct board grinding treatment on the PCB. The
servo motor works to drive the rotating shaft to rotate, and therefore the gear is driven to rotate. Due to the fact that the gear is engaged with the rack, the
servo motor can drive the board grinding mechanism to move longitudinally. Meanwhile, the X-axis feeding mechanism can drive the PCB placed in the carrying die to move transversely, and therefore automatic board grinding can be conducted on the PCB. The longitudinal moving type PCB board grinding device is simple in structure and capable of automatically conducting board grinding treatment on the PCB, meanwhile,
abrasive materials make even contact with the PCB, board grinding is even and continuous, and the
automation degree is high. Meanwhile,
integrated design is adopted, and the cost is effectively reduced.
