The pitch-changing slide rail 65 and the pitch-changing slider 66 are located on the upper surface of the rotating beam 3. The fixture connecting base plate 41 of the material receiving and adsorption fixture 4 is mounted on the pitch-changing slider 66. The floating belt clamp 64 connects the synchronous belt 63 and the fixture connecting base plate 41 from the side of the rotating beam 3.

A floating spring 646 is provided on the floating adapter shaft 644 between the floating bushing 645 and the floating fork. A synchronous belt 63 is fixedly connected between the clamp body 641 and the outer side of the adapter block body of the variable pitch adapter block 642. The top side of the variable pitch floating block 643 is connected to the outer side of the fixture connecting base plate 41 of the receiving adsorption fixture 4.

Two sets of longitudinal moving track modules 100 are arranged side by side on the platform to support and drive the longitudinal overall movement of the rotating material platform 200. The rotating material platform 200 is arranged horizontally and vertically on the longitudinal moving track module 100 to adsorb, carry, and adjust materials. The gantry frame 300 spans across the longitudinal moving track module 100 to support the optical drive module 400 and the optical detection module 500. The optical drive module 400 drives the lateral position and height of the optical detection module 500. The receiving module 600 is adapted to the corresponding side of the rotating material platform 200 for receiving and unloading materials.

[0030] During the actual material receiving process, the rotating material stage 200, after the inspection is completed, drives the material adsorption fixture to rotate outward, changing from horizontal to vertical. Correspondingly, the material receiving adsorption fixture of the receiving module 600 rotates towards the rotating material stage 200 to become vertical. The suction nozzle of the material receiving adsorption fixture approaches the strap on the material adsorption fixture. One starts the vacuum to generate negative pressure adsorption, and the other stops the vacuum to release the strap, thus completing the material receiving.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
