[0014] In a possible design, the lifting mechanism includes four electric push rods for lifting four frames, the fixed parts of the four electric push rods are respectively fixedly connected to the bottoms of the four moving blocks, and the tops of the four frames are respectively fixedly connected to the telescopic parts of the four electric push rods.

[0015] In a possible design, the second moving mechanism includes a second motor, a second bidirectional screw and two moving plates, a groove is provided on the top inner wall of the frame, one side of the second motor is fixedly connected to the inner wall of one side of the groove, one end of the second bidirectional screw is fixedly connected to the output end of the second motor, the other end of the second bidirectional screw is rotatably connected to the inner wall of one side of the groove, the tops of the two moving plates are both slidably connected to the top inner wall of the groove, a second screw nut is embedded in one side of the moving plate, the second screw nut is threadedly connected to the second bidirectional screw, and the tops of the two cover bodies are respectively fixedly connected to the bottoms of the two moving plates.

[0016] In a possible design, the clamping mechanism includes two fixing clamps, two clamping plates and two threaded rods. Support plates are fixedly provided on both sides of the top of the machine platform. The bottoms of the two fixing clamps are fixedly connected to the tops of the two support plates, one side of the two clamping plates is slidingly connected to the inner wall of one side of the two fixing clamps, the two threaded rods are threadedly connected to the two fixing clamps, the bottom end of the threaded rod is rotatably connected to the top of the clamping plate, and the top end of the threaded rod is fixedly provided with a knob for facilitating the rotation of the threaded rod.

The telescopic part of the electric push rod pushes the frame and the drill bit to move downward, which is convenient for drilling holes in the PCB board. The first motor drives the drill bit to rotate for drilling operations. After the drilling is completed, the electric push rod contracts and the drill bit is raised. Since four workstations are set, namely, four first motors and four drill bits can drill holes in the four corners of the PCB board at the same time, thereby improving efficiency. The first motor, the second motor and the third motor can select stepper motors, and the first motor, the second motor, the third motor and the electric push rod can be controlled by an external controller.
