[0031] In the technical solution of this application, such as Figure 3 As shown, the feeding mechanism includes a mounting plate 3, on which a fixing plate is fixedly mounted. A third motor 9 is fixedly mounted on the fixing plate. The output end of the third motor 9 passes through the fixing plate and is fixedly mounted on a rotating frame 8. When the third motor 9 is started, the rotating frame 8 is driven to rotate, thereby rotating the clamped circuit board to a vertical position, which is convenient for tin plating.

[0032] In the technical solution of this application, such as Figure 2 and 4 As shown, a fourth motor 7 is fixedly installed on the rotating frame 8. A bidirectional lead screw 12 is fixedly installed at the output end of the fourth motor 7. A moving block is threaded onto the bidirectional lead screw 12. When the fourth motor 7 is started, the bidirectional lead screw 12 is rotated, thereby moving the moving block.

[0033] In the technical solution of this application, such as Figure 3 As shown, a clamping plate 10 is fixedly installed on the moving block, and a connecting telescopic rod 11 is fixedly installed on the clamping plate 10. The other end of the connecting telescopic rod 11 is fixedly connected to the side wall of the rotating frame 8. When the moving block moves, it will drive the clamping plate 10 to move. Under the action of the connecting telescopic rod 11, it can be extended.

[0034] In the technical solution of this application, such as Figure 3 As shown, a protective pad is fixedly installed on the other side of the clamping plate 10, which can protect the circuit board by clamping it and prevent damage to the circuit board.

[0035] In the technical solution of this application, such as Figure 5 As shown, a second bidirectional lead screw 13 is fixedly installed at the output end of the first motor 6 through the side wall of the device body 1. A sliding block 14 is threaded onto the second bidirectional lead screw 13. A limit block is fixedly installed on the sliding block 14.

Start the electric push rod 5 to move the feeding mechanism down. Start the fourth motor 7 to rotate the bidirectional lead screw 12, thereby moving the moving block. When the moving block moves, it will move the clamping plate 10 to clamp the circuit board. Then, by rotating the rotating rod, the circuit board is moved into the device body 1. Then, start the third motor 9 to rotate the rotating frame 8, which can rotate the clamped circuit board to the vertical direction for soldering.

The circuit board can be soldered through the nozzle 15. The soldering material can be transported by the liquid pump.
