The semiconductor components are tested at different stations through numerous suction nozzles with air pressure suction on the high-speed rotating table. The defective products are classified through polarity testing, steering positioning, performance testing, visual inspection (2D, 3D, 5S), printing, and steering processes, and the qualified products are finally put into taping and packaging.

[0003] Among them, after the tape packaging is completed, it is necessary to use the inkjet mechanism to mark the IC component model, serial number, production date and other information on the tape, which can reduce the time required for processing and improve work efficiency.

When in use, the electric push rod 91 is started by the single chip computer 10, and the telescopic end of the electric push rod 91 drives the U-shaped plate 92 to move upward, and the edges of the left and right ends of the braid are clamped by the cooperation of the guide wheel 1 94 and the guide wheel 2 95;

[0028] At the same time, the convex column on the outer arc surface of the guide wheel 94 is inserted into the hole on the surface of the braid, limiting the relative sliding of the guide wheel 94 and the braid, and then overcoming the elastic force of the tension spring 967 and pulling the sleeve 965 forward, so that the card plate on the outer arc surface of the sleeve 965 leaves between the two adjacent limit plates 968, and at this time, the sleeve 965 and the synchronous pulley 2 963 can rotate relative to each other and rotate the sleeve 965;

Under the torsion of the torsion spring 966, the right guide wheel 94 always applies a rightward force to the braid to tighten the braid.

[0032] Then start the high-pressure pump 7 to spray the ink in the ink cartridge 5 from the nozzle 4 to print on the surface of the tape to mark the IC component model, serial number, production date and other information. During the coding process, start the screw motor 11, and the screw motor 11 is threadedly connected to the screw hole of the slide plate 3 to drive the slide plate 3 to slide in the slide groove 2 to adjust the position of the nozzle 4.
