[0043] The working principle of the SMT placement machine with rapid curing of the substrate provided by this utility model is as follows:

[0044] A conveyor frame 6 is installed on top of the placement table 7. A conveyor belt 26 is then installed in the conveyor frame 6 via multiple rotating shafts 27. Multiple sets of second magnetic blocks 25, each consisting of three magnetic blocks, are installed on the outer surface of the conveyor belt 26.

After the mounting is completed, the drive assembly 11 drives the conveyor belt 26 to work, which can move the mounting frame 22 containing the mounted circuit board into the drying frame 9. Then the mounting equipment mounts another mounting frame 22 containing a circuit board. During the mounting process, the conveyor belt 26 stops working, which also allows the circuit board to have sufficient drying time inside the drying frame 9. The circuit board located in the drying frame 9 is quickly cured by the hot air sprayed by the jet assembly 10. After curing, it will move out of the drying frame 9 with the movement of the conveyor belt 26. The operator only needs to remove the mounting frame 22 from the stabilizer 15.

[0046] To improve the stability and rapid curing of SMT placement during transport, a transport frame 6 is installed on top of the placement table 7.
