[0036] Working principle: When in use, the LED lamp beads are placed in the working area on the top of the workbench 2, and then the electric guide rail 2 11 and the electric guide rail 3 12 are controlled to move the dispensing needle 14 under the dispensing machine body 13 to the top of the LED lamp beads that need to be dispensed. Then the dispensing needle 14 will move downward to squeeze the protective cover 17, so that the protective cover 17 overcomes the elastic force of the torsion spring 19 and rotates downward until the dispensing needle 14 extends to the outside of the protective shell 16, so as to facilitate the dispensing of the LED lamp beads above the workbench 2.

[0037] By starting the electric guide rail 1 5, the slider 6 is displaced to the left, and the displacement of the slider 6 drives the workbench 2 to move to the left through the pin shaft 1 3 and the pin shaft 2 4. When the workbench 2 moves to the left side of the guide rail 7, the pin shaft 2 4 will move downward under the action of the arc end of the guide groove 8, so that the workbench 2 is tilted. As the slider 6 moves to the left, the workbench 2 finally moves to a vertical state, and then the LED lamp beads above the workbench 2 fall downward under the action of gravity, and after being guided and concentrated by the blanking plate 9, they fall into the inside of the collection box 10 for easy access.

[0038] When the protective shell 16 needs to be replaced and cleaned, the control rod 18 is pressed so that the two groups of control rods 18 overcome the elastic force of the spring 19 and move closer to each other, so that the wedge block on the top of the control rod 18 is disengaged from the inside of the control groove 20, and the limit of the control rod 18 on the control groove 20 is cancelled. Then, the protective shell 16 can be easily and quickly removed from the bottom of the dispensing machine body 13 for replacement, which is convenient for cleaning the inside of the protective shell 16. The operation is simple and fast, and the work efficiency is improved.
