The tail end of the wire soldered on the circuit board is placed on the auxiliary conveying mechanism 130, so that not only the auxiliary supporting function but also the conveying function for the cable can be achieved.

Further, referring to fig. 11, the motor driving the auxiliary conveying mechanism 130 drives one of the belt conveying mechanisms 100 to operate through the transmission mechanism, so that the loading and unloading of the positioning fixture 3 are performed simultaneously, the loading and unloading are performed sequentially, and a driving power can be reduced.

the present invention is not limited to the above-described embodiments, and those skilled in the art will be able to make various modifications without creative efforts from the above-described conception, and fall within the scope of the present invention.
