[0022] like Figure 3 As shown, the positioning assembly includes an electromagnet 9 and a two-way cylinder 10. Two two-way cylinders 10 are installed between the discharge plate 8 and the base plate 7 by bolts. The two two-way cylinders 10 are distributed in a cross structure. The two telescopic rods of the two two-way cylinders 10 are connected with electromagnets 9 for limiting the circuit board. The electromagnets 9 are located on the left and right sides and the front and back sides of the discharge plate 8. A soft layer is provided on the telescopic end of the electromagnet 9 at the position in contact with the circuit board to avoid wear of the circuit board. The electromagnet 9 and the two-way cylinder 10 are both electrically connected to the controller 101.

[0023] like Figure 1 As shown, the power assembly includes an electric push rod 3 and a first fixed plate 4. Two first fixed plates 4 are connected to the left and right side walls of the upper part of the shell 1. An electric push rod 3 is installed between the two first fixed plates 4 on the same side by bolts. The telescopic rods of the electric push rod 3 are respectively connected to the front sides of the two ends of the push plate 11 to drive the push plate 11 to move. The electric push rod 3 is electrically connected to the controller 101.

[0024] like Figure 4As shown, it also includes a connecting plate 13, a fan 14, a telescopic tube 15 and an air outlet pipe 16. The connecting plates 13 are symmetrically welded on the left and right sides of the rear side wall of the shell 1. The fan 14 for blowing air is installed between the connecting plates 13.

[0025] When drilling holes in a circuit board, first operate the controller 101 to start the mobile platform 6, and use the mobile platform 6 to drive the base plate 7 and the discharge plate 8 to be pushed forward, then place the circuit board on the discharge plate 8, and then start the electromagnet 9 to extend the telescopic end of the electromagnet 9 so that it is located on the left and right and front and back positions of the circuit board.

The push plate 11 pushes the circuit board to the discharge platform 2 to achieve automatic unloading, making it convenient for the operator to take out the processed circuit board. After completing the operation, the telescopic rod of the electric push rod 3 shortens and resets, driving the push plate 11 to move backward and reset, and then driving the outlet pipe 16 to move backward and reset. After resetting, the fan 14 and the electric push rod 3 are turned off. According to the above operation, the positioning drilling of the remaining circuit boards can continue.
