The lifting screw assembly 5 is an existing conventional product, which can adjust the height of the base 4, and the universal wheel 6 with a brake can achieve position fixation.

[0043] Working principle: Move the device to the side of the SMT machine, and extend the feeding bottom plate 13 of the feeding device 1 to the side of the circuit board feeding mechanism of the SMT machine on the workbench. Adjust the height of the base 4 by adjusting the lifting screw group 5, and step on the brake of the universal wheel 6 to fix the position of the device to prevent movement during processing. Place the loading tray 8 containing various chip materials to be processed in the mobile tray 9, and place the mobile tray 9 between the left slot plate 21 and the right slot plate 28 of the tray station assembly. The stepper motor 24 of the lifting tray station device 2 runs, drives the synchronous shaft 23 to rotate, and drives the lifting and lowering of the tray station assembly through the lifting synchronous belt 27. When the mobile tray 9 containing the chips to be mounted is lifted to the same height as the feeding bottom plate, the stepper motor 24 stops rotating. The stepper motor 24 of the feeding device 1 rotates, and the feeding synchronous belt 11 drives the electromagnet fixing seat 15 to move close to the entrance of the feeding base plate. When the reset photoelectric sensor 211 senses the feeding photoelectric baffle 18, the stepper motor 24 stops rotating. The electromagnet 14 on the electromagnet fixing seat 15 is energized to adsorb the mobile tray 9 of the lifting tray station device 2. Then the stepper motor 24 reverses, and the electromagnet fixing seat 15 drives the mobile tray 9 to move in the opposite direction to the exit of the feeding base plate. The positioning photoelectric sensor 212 senses the feeding photoelectric baffle 18, and the stepper motor 24 stops rotating. If the proximity switch 19 senses the mobile tray 9, the placement machine will perform the placement work. If the mobile tray 9 is not sensed, the placement work will not be performed. After the placement is completed, the stepper motor 24 rotates, and the electromagnet fixing seat 15 sends the mobile tray 9 back to the lifting tray station device 2. The electromagnet 14 is powered off and no longer adsorbs the mobile tray 9. In the present application, the control of each sensor, stepper motor 24, and electromagnet 14 is achieved by connecting to the computer of the placement machine and performing signal control, which is an existing conventional control technology and will not be described in detail here.
