[0002] Glass substrates, also known as glass plates, are thin sheets of glass with extremely smooth surfaces. They possess excellent optical properties, including high transparency and low light scattering, offering up to 92% visible light transmittance across a broad ultraviolet to mid-infrared wavelength range, ensuring image clarity in display devices. They also exhibit good electrical properties, possessing insulation and voltage resistance, making them suitable for electronic packaging applications and widely used in integrated circuits, flexible electronics, and other electronic fields.

[0023] Please see Figures 1-5 A vacuum adsorption structure for polishing glass substrates includes four suction cups 1 and four sets of suction cup adjustment components. The four sets of suction cup adjustment components are evenly connected to a base plate 2, and each set of suction cup adjustment components is connected to one suction cup 1. The four sets of suction cup adjustment components are connected to a common drive component. The suction cups 1 are connected to an air source and a vacuum generator. They are used to adsorb glass substrates.

[0024] Specifically, the suction cup adjustment assembly includes two fixed seats 3, a lead screw 4, and a lead screw nut 5. A through groove 6 is formed on the base plate 2, and the two fixed seats 3 are connected to the upper surface of the base plate 2 and located at both ends of the through groove 6. The lead screw 4 is rotatably connected to the two fixed seats 3, and the lead screw nut 5 is connected to the lead screw 4. The lead screw nut 5 is connected to the suction cup 1 via a quick-release assembly. One end of the lead screw 4 is connected to a first drive gear 7, which is connected to a drive assembly. The drive assembly includes a ring gear drive gear 8, a rotating shaft 9, and a motor 10. The output end of the motor 10 is connected to the rotating shaft 9, and the other end of the rotating shaft 9 is connected to the ring gear drive gear 8. The end face teeth of the ring gear drive gear 8 mesh with the first drive gear 7. The upper end of the base plate 2 is connected to a top cover 18, and the motor 10 is connected to the top cover 18.

[0025] Specifically, the rotation of motor 10 drives the ring gear drive gear 8 to rotate, the rotation of the ring gear drive gear 8 drives the meshing first drive gear 7 to rotate, the rotation of the first drive gear 7 drives the lead screw 4 to rotate, the rotation of the lead screw 4 drives the connected lead screw nut 5 to move, and the movement of the lead screw nut 5 drives the connected suction cup 1 to move. The forward rotation of motor 10 drives the lead screw 4 to rotate forward, and the forward rotation of lead screw 4 drives the connected suction cup 1 to move towards the edge of the base plate 2. The reverse rotation of motor 10 drives the lead screw 4 to rotate in reverse, and the reverse rotation of lead screw 4 drives the connected suction cup 1 to move closer to the center of the base plate 2.

[0026] Specifically, by setting up four sets of suction cup adjustment components connected to a single drive component, the four suction cups 1 can move outwards simultaneously or move towards the center simultaneously. The suction cups 1 can change positions and can adsorb glass substrates of different sizes for polishing operations.

[0027] Specifically, the quick-release assembly includes a connecting seat 11, with a lead screw nut 5 connected to the upper end of the connecting seat 11 and a deep hole 12 at the lower end. A threaded sleeve 13 is connected inside the deep hole 12. A screw 14 is connected to the upper end of the suction cup 1, and the screw 14 is threadedly connected to the threaded sleeve 13. A threaded hole 15 is formed on the side wall of the connecting seat 11, and an insertion hole 16 is formed on the outer wall of the threaded sleeve 13. A fixing bolt 17 passes through the threaded hole 15 and into the insertion hole 16.

[0028] Specifically, when replacing the suction cup, simply rotate the suction cup to remove it from the threaded sleeve 13. The new suction cup is then threaded onto the threaded sleeve 13 via its own screw 14. The threaded sleeve 13 is secured within the deep hole 12 by two fixing bolts 17, ensuring a stable connection and preventing it from easily falling off.

[0029] Specifically, the upper end face of the top cover 18 is connected to the connecting flange 20 via multiple connecting rods 19. The connecting flange 20 is used to connect to the robotic arm. The robotic arm drives the vacuum adsorption structure to adsorb the glass substrate for polishing.

[0030] This vacuum adsorption structure for polishing glass substrates features four sets of suction cup adjustment components, each connected to a suction cup 1. Driven by a driving component, the four suction cups 1 can simultaneously move outwards or towards the center. The positions of the suction cups 1 can be changed, allowing for the adsorption and polishing of glass substrates of different sizes. The mechanical movement enables the adjustment of the suction cup 1 positions, making operation more convenient.
