[0029] Specifically, the inner wall of the electric slide rail 302 slides in contact with the outer surface of the electric slider 303, the outer surface of the detection probe 3031 is provided with a plurality of lighting lamp heads, the front surface of the No. 2 electric conveyor belt 5 is infinitely close to the rear surface of the No. 1 electric conveyor belt 2, and the height thereof is consistent with the No. 1 electric conveyor belt 2, and the detection probe 3031 and the rotating motor 501 are respectively electrically connected to the controller 301 through wires;

[0030] In this embodiment, the sliding cooperation between the electric slide rail 302 and the electric slider 303 is mainly used to adjust the position of the detection probe 3031, wherein the lighting lamp head can illuminate the SMT patch to facilitate the detection of it by the detection probe 3031, and the setting of the rotating motor 501 is mainly used to drive the guide lever 502, so that the guide lever 502 can guide the SMT patch to move and move it to the No. 2 electric conveyor belt 5, thereby meeting the sorting needs of users.

[0031] In this embodiment, please refer to Figure 1 and Figure 4 The positioning and adjusting mechanism 4 includes a fixed sleeve 401 fixedly mounted on the top of the base plate 1, a locking bolt 402 is arranged on the outer surface of the fixed sleeve 401, and an adjusting column 403 is arranged on the top thereof, and a positioning plate 404 is fixedly mounted on the top of the adjusting column 403;

[0032] Specifically, the fixing sleeve 401 is symmetrically arranged front and back about the top surface of the bottom plate 1, the bottom end of the adjusting column 403 movably penetrates the top end of the fixing sleeve 401 and extends into the inside thereof, and the locking bolt 402 is threadedly penetrated through the outer surface of the fixing sleeve 401 near one end and is in close contact with the outer surface of the adjusting column 403;
