[0002] Glass-ceramics refers to glass that has been added with certain nucleating substances, and then precipitated with a large number of tiny crystals uniformly through heat treatment, light irradiation, or chemical treatment, forming a dense multiphase complex of microcrystalline phase and glass phase. By controlling the type, quantity, and size of the microcrystals, transparent glass-ceramics, glass-ceramics with zero expansion coefficient, surface-strengthened glass-ceramics, and glass-ceramics of different colors or machinable glass-ceramics can be obtained.

[0024] By adopting the above technical solution, when the screw rod rotates, the lifting block drives the connecting plate to descend. During the descent, the splicing wheel will first be spliced ​​with the square shaft portion of the second connecting shaft. At this time, the connecting plate continues to descend. Due to the cooperation between the square shaft portion and the splicing wheel, the splicing wheel will not descend at this time, which will cause the compression spring to compress, and the connecting plate continues to descend. The first gear and the second gear are meshed. At this time, the second gear cannot continue to descend, and the rack will continue to move with the connecting plate. The rack drives the first gear to rotate, and then drives the second gear to rotate, and then drives the splicing wheel to rotate. The splicing wheel drives the second bevel gear on the second connecting shaft to rotate, and the second bevel gear drives the first connecting shaft to rotate through the first bevel gear, thereby realizing the rotation of the linkage wheel, and the linkage wheel can realize all the functions through the connecting rod.

[0028] 1. The glass is processed through five steps: primary fine carving, 16B double-sided grinding, secondary fine carving 2.5D, side polishing and 2.5D double-sided scanning. Compared with the traditional process, two processes are reduced, the processing time is shortened by 55%, and the glass has no significant difference compared with the traditional processing technology after 4PB testing. Therefore, the process of this application can improve processing efficiency and reduce costs;

[0029] 2. Use the positioning plate to position the glass, place the glass on the supporting block, and make the edge of the glass fit the arc surface of the positioning plate, so that the position of the glass can be easily positioned, and then the position of the glass is fixed by vacuum adsorption, and then the supporting block slides to the outside, and the polishing wheel descends to grind the peripheral edge of the glass;

[0030] When the polishing wheel is lowered, the lifting block drives the connecting plate to move downward, and the plug-in wheel will first be plugged into the square shaft portion of the second connecting shaft, and then the plug-in wheel cannot move downward. During the subsequent lowering process of the connecting plate, the compression spring is compressed. During this process, the first gear descends and meshes with the second gear. After meshing, the first gear cannot move downward. Under the action of the rack, the first gear rotates, driving the second gear to rotate. The second gear drives the second connecting shaft to rotate through the plug-in wheel, and the second connecting shaft drives the linkage wheel to rotate through the second bevel gear and the first bevel gear to realize the sliding of the supporting block. When polishing is completed, the mounting plate drives the polishing wheel to rise, the lifting block drives the connecting plate to rise, and the rack rises accordingly. When the rack rises, an upward force is generated on the first gear, and the first gear will move upward with the rack. At this time, it cannot drive the second gear to rotate, and contacts the lock of the second gear. Under the action of the reset tension spring, the supporting block is reset, and the plug-in wheel will rotate. After the supporting block is reset, the compression spring also gradually recovers, and then the plug-in wheel is separated from the square shaft portion. BRIEF DESCRIPTION OF THE DRAWINGS

This application takes four supporting blocks 2 as an example for explanation. The supporting blocks 2 are cylindrical, and the four supporting blocks 2 are evenly distributed along the circumferential array direction. The supporting blocks 2 are used to support circular glass and fix the glass by vacuum adsorption; the supporting blocks 2 slide on the base 1, and four positioning plates 3 are fixedly installed in the middle position of the base 1. The four positioning plates 3 correspond to the four supporting blocks 2 one by one. The positioning plates 3 are arranged in an arc shape, and the center of curvature of the positioning plates 3 is located on one side of the corresponding supporting blocks 2. When the supporting blocks 2 slide to the side of the corresponding positioning plates 3, the glass is placed on the supporting blocks 2, and the edge of the glass is abutted against the positioning plates 3, so that the position of the glass can be positioned.

Each support block 2 corresponds to a processing station, and four are taken as an example in this application. In fact, the number of support blocks 2 can be adjusted according to actual processing needs, and the number is not limited.

[0056] The second motor 53 rotates to drive the polishing wheel 51 to rotate, and the first motor 52 rotates to drive the second motor 53 to make a circular motion, that is, to drive the polishing wheel 51 to make a circular motion. The mounting plate 4 descends, so that the polishing wheel 51 contacts the edge of the glass, and the polishing wheel 51 rotates to polish the edge of the glass. The polishing wheel 51 makes a circular motion along the circumference of the glass, and the polishing action of the peripheral edge of the glass can be realized.

[0057] Reference Figure 3 , Figure 4 and Figure 5 The base 1 is provided with four sliding grooves 13 corresponding to the four supporting blocks 2. The four sliding grooves 13 correspond to the four supporting blocks 2 one by one. The lower side of the supporting block 2 is integrally formed with a sliding block 21. The sliding block 21 slides in the corresponding sliding groove 13. The side of the sliding block 21 close to the positioning plate 3 is integrally formed with a limiting rod 22. The base 1 is provided with a reset spring 23 in the sliding groove 13. The reset spring 23 is located on the side of the sliding block 21 close to the positioning plate 3. The reset spring 23 is sleeved on the peripheral side of the limiting rod 22. One end of the reset spring 23 is connected to the sliding block 21, and the other end of the reset spring 23 is connected to the end of the sliding groove 13. In the initial state, under the action of the reset spring 23, the supporting block 2 is located on the side close to the positioning plate 3, and the limiting rod 22 abuts against the end of the sliding groove 13 to locate the position of the supporting block 2. The base 1 is provided with a linkage assembly 6 that drives all the sliding blocks 21 to slide synchronously.

[0058] Reference Figure 5 and Figure 6The base 1 is provided with a receiving groove 14, which is connected to the vertical groove 111. The linkage assembly 6 includes a linkage wheel 61 and a connecting rod 62. The base 1 is located in the receiving groove 14 and is rotatably connected to a first rotating shaft 15. The first rotating shaft 15 rotates vertically. The linkage wheel 61 is coaxially fixed on the upper side of the first rotating shaft 15. A driving rod 611 is fixedly connected to the upper side of the linkage wheel 61. The driving rod 611 is eccentrically arranged with the linkage wheel 61. The driving rod 611 is arranged vertically. There are four driving rods 611. The four driving rods 611 are distributed on the linkage wheel 61 at intervals. There are four connecting rods 62. The four driving rods 611 correspond to the four connecting rods 62 one by one, and the four connecting rods 62 correspond to the four sliding blocks 21 one by one. One end of the connecting rod 62 is hinged to the corresponding driving rod 611, and the other end of the connecting rod 62 is hinged to the corresponding sliding block 21. The base 1 is provided with a driving assembly 10 for driving the linkage wheel 61 to rotate.

[0059] In the initial state, under the action of the reset spring 23, the support block 2 is located on the side close to the positioning plate 3. At this time, the glass is placed on the support block 2, and the position of the glass is positioned by the positioning plate 3. After positioning, the support block 2 adsorbs and fixes the glass, and then the driving component 10 drives the linkage wheel 61 to rotate. The linkage wheel 61 drives the sliding block 21 to slide in the sliding groove 13 through the screw rod 12, so that the support block 2 slides away from the positioning plate 3; then the mounting plate 4 descends, and the polishing wheel 51 polishes the glass. When the polishing operation is completed, the reset spring 23 will drive the support block 2 to reset.

[0060] Reference Figure 3 , Figure 5 and Figure 7 The lifting block 41 is fixedly connected with a connecting plate 7, which is located in the vertical slot 111. The connecting plate 7 is vertically arranged, and a first lifting slot 71 and a second lifting slot 72 are provided on the connecting plate 7 in the vertical direction. The first lifting slot 71 is located above the second lifting slot 72. The connecting plate 7 is located in the first lifting slot 71 and a first connecting block 8 slides therein, and the connecting plate 7 is located in the second lifting slot 72 and a second connecting block 9 slides therein; a first connecting shaft 81 is rotatably connected to the first connecting block 8, and a first gear 82 is coaxially fixed to the first connecting shaft 81. A rack 73 is fixedly connected to the connecting plate 7 in the vertical direction, and the rack 73 meshes with the first gear 82. In the initial state, due to gravity, the first connecting block 8 is located at the lower end of the first lifting slot 71.

[0061] The connecting plate 7 is located in the second lifting groove 72 and is provided with a compression spring 74. The compression spring 74 is located above the second connecting block 9. The compression spring 74 is vertically arranged. One end of the compression spring 74 is connected to the second connecting block 9, and the other end of the compression spring 74 is connected to the upper groove wall of the second lifting groove 72. The second connecting block 9 is rotatably connected with a second connecting shaft 91, and a second gear 92 is coaxially fixed on the second connecting shaft 91. The second gear 92 is located below the first gear 82, and the diameter of the second gear 92 is smaller than the first gear 82; a plug-in wheel 93 is also coaxially fixed on the second connecting shaft 91, and the plug-in wheel 93 is radially provided with a plug-in groove 931. The plug-in wheel 93 is located on both sides of the opening of the plug-in groove 931 and has counterweights. The counterweights will cause the plug-in groove 931 of the plug-in wheel 93 to be opened downward.

[0062] The driving assembly 10 includes a first bevel gear 101 and a second bevel gear 102. The first bevel gear 101 is coaxially fixed on the first rotating shaft 15. The base 1 is located in the accommodating groove 14 and is also rotatably connected to the second rotating shaft 16. The second rotating shaft 16 rotates in a horizontal direction. The second bevel gear 102 is coaxially fixed on the second rotating shaft 16. A square shaft portion 161 is formed at one end of the second rotating shaft 16 away from the first rotating shaft 15.

[0063] When the screw rod 12 rotates to drive the lifting block 41 to descend, the connecting plate 7 descends accordingly, and the plug-in wheel 93 is plugged into the square shaft portion 161 of the second rotating shaft 16 to form a coaxial fit. After that, the plug-in wheel 93 cannot continue to descend. When the connecting plate 7 continues to descend, the compression spring 74 is compressed; when the connecting plate 7 continues to descend, the first gear 82 and the second gear 92 are meshed. After that, the first gear 82 cannot continue to descend. The first connecting block 8 will slide relatively in the first lifting groove 71, and the rack 73 will continue to descend with the connecting plate 7. At this time, the first gear 82 will be relatively displaced on the rack 73, and the first gear 82 will rotate while walking on the rack 73, thereby driving the second gear 92 to rotate. Because the rack 73 will generate a downward force on the first gear 82, the meshing effect of the first gear 82 and the second gear 92 is better. The second gear 92 drives the plug-in wheel 93 to rotate, the plug-in wheel 93 drives the second rotating shaft 16 to rotate, and the second rotating shaft 16 drives the first rotating shaft 15 to rotate through the second bevel gear 102 and the first bevel gear 101, thereby realizing the rotation of the linkage wheel 61 and the sliding of the supporting block 2.

[0064] When the polishing operation is completed, the screw rod 12 drives the lifting block 41 to rise, driving the connecting plate 7 to rise. When rising, the rack 73 will rise accordingly. At this time, because the rack 73 exerts an upward force on the first gear 82, the meshing effect between the first gear 82 and the second gear 92 is poor, that is, the second gear 92 cannot drive the first gear 82 to rotate well.
