[0023] The revolution drive unit 23 is located at one end plate 22 of the platform, and a revolution angle measuring component 27 is located at the other end plate 22 of the platform for revolution angle monitoring and limiting.

[0024] The self-rotation drive unit 26 includes a self-rotation driver, a transmission pulley set, a transmission rod, and multiple steering gears; the multiple steering gears are evenly distributed on the top plate 24 of the platform and are connected in series through multiple horizontally arranged transmission rods.

[0025] The material adsorption fixture 25 includes a fixture adapter, a fixture adsorption body, a fixture nozzle, and a short-side reference block; the lower part of the fixture adapter is connected to the top output shaft of the variable transmission of the self-rotating drive unit 26 and the vacuum passage. The short-side reference block is used for end stop limiting of the watch strap.

[0026] The gantry frame 300 includes gantry columns 31 and gantry beams 32, with the bottom ends of the gantry beams 32 installed on the tops of the two gantry columns 31.

[0027] The optical drive module 400 includes an optical lateral drive module 41, a lifting adapter plate 42, and an optical lifting drive module 43. The optical lateral drive module 41 is located between the side of the gantry beam 32 of the gantry frame 300 and the lifting adapter plate 42, driving the lifting adapter plate 42 to move horizontally along the gantry beam to adjust the alignment of the optical detection module 500 with the rotating material platform 200. The optical lifting drive module 43 is located between the other side of the lifting adapter plate 42 and the optical detection module 500, driving the optical detection module 500 to move closer to or further away from the rotating material platform 200.

[0028] In a specific example, the optical lateral drive module 41 and the optical lifting drive module 43 can be made of motor lead screw assembly, linear motor assembly, cylinder slider assembly, etc. The illustrated example uses a motor lead screw assembly.

[0029] The optical detection module 500 includes a camera 52, an optical lens 53, a coaxial light source 54, a first ring light 55, a second ring light 56, a four-zone bar light 57, and a three-zone bar light 58 arranged sequentially from top to bottom on an inclined adapter 51.

[0030] Second Embodiment See Figure 4 and Figure 5 Two sets of rotating material platforms 200 are set on the longitudinal moving ground rail module 100; corresponding to the two sets of rotating material platforms 200, an optical drive module 400 and an optical detection module 500 are respectively set on the longitudinal front and rear sides of the gantry 300.

[0031] The first and second embodiments are in a five-degree-of-freedom linkage configuration.

[0032] Third Embodiment See Figure 6 and Figure 7 A set of rotating material receiving modules 600 is provided on the outer side of the longitudinal end of the longitudinal track module 100. The rotating material receiving module 600 is adapted to the rotating material platform 200 on the corresponding side for receiving and unloading materials. This embodiment adds one rotational degree of freedom, for a total of six degrees of freedom.

[0033] The rotating receiving module 600 includes a rotating column 61, a rotating beam 62, a receiving rotating driver 63, and a receiving adsorption fixture 64. Multiple receiving adsorption fixtures 64 are disposed on the rotating beam 62. The receiving rotating driver 63 drives the rotating beam 62 to rotate and is adapted to the rotating material platform 200 to receive materials.

[0034] During the actual material receiving process, the rotating material stage 200, after the inspection is completed, drives the material adsorption fixture 25 to rotate outward, changing from horizontal to vertical. Correspondingly, the material receiving adsorption fixture 64 of the rotating material receiving module 600 rotates towards the rotating material stage 200 to become vertical. The suction nozzle of the material receiving adsorption fixture 64 approaches the strap on the material adsorption fixture 25. One starts a vacuum to generate negative pressure adsorption, and the other stops the vacuum to release the strap, thus completing the material receiving process.

[0035] To accommodate the narrow, elongated shape of the watch strap, the adsorption bearing surfaces of both the material adsorption fixture 25 and the receiving adsorption fixture 64 are rectangular surfaces adapted to the watch strap.

[0036] Furthermore, a dust removal ion air knife assembly 700 is installed below the gantry beam 32 of the gantry frame 300 for dust removal from the strap of the rotating material carrier 200.
