[0019] To better understand this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1 and 2The multifunctional glass grinding head assembly shown includes a housing 10, which is a square box with a lifting mechanism 20 inside. The lifting mechanism 20 includes a lifting motor 21, a lead screw 22, a lead screw nut 23, a lifting plate 24, and a retaining arm 25. The lifting motor 21 is fixedly installed on the inner wall of the housing 10. The lead screw 22 is upright below the lifting motor 21 and rotatably mounted on a rod seat provided on the inner wall of the housing 10. The top end of the lead screw 22 is connected to the lifting motor 21. The lead screw nut 23 is screwed onto the lead screw 22. The back of the lifting plate 24 is fixedly connected to the lead screw nut 23 and slides on the longitudinal guide rail provided on the inner wall of the housing 10. There are two retaining arms 25, which are fixedly mounted on the front of the lifting plate 24 with a vertical distance between them.

[0021] like Figures 2 to 4 As shown, the lifting mechanism 20 is connected to the grinding wheel mechanism 30, which includes a main motor 31, a wheel axle 32, a grinding wheel assembly 33, a pressure plate 34, and a locking bolt 35. The main motor 31 is cylindrical and vertically fixed within two clamping arms 25, with its bottom protruding below the housing 10 through a through hole on the bottom surface of the housing 10. The top of the wheel axle 32 is inserted into the shaft hole at the bottom of the main motor 31 and is connected to the main motor 31, while its bottom protrudes vertically below the main motor 21. The grinding wheel assembly 33 includes a coarse grinding wheel 33.1, a fine grinding wheel 33.2, a polishing wheel 33.3, and a chamfering wheel 33.4, which are sequentially fitted from top to bottom or bottom to top. On the connector 32.1 integrally formed at the bottom center of the wheel axle 32, the pressure plate 34 is sleeved on the locking bolt 35 through its central through hole. The locking bolt 35 is screwed into the screw hole provided on the bottom surface of the connector 32.1 to fix the grinding wheel assembly 33 to the wheel axle 32. The main motor 31 can be driven by the lifting mechanism 20 to move up and down in the through hole, thereby driving the grinding wheel assembly 33 to move along the Z-axis direction below the housing 10. The downward movement of the grinding wheel assembly 33 can cause the coarse grinding wheel 33.1, fine grinding wheel 33.2, polishing wheel 33.3 and chamfering wheel 33.4 to enter the edge grinding station in sequence to process the glass. The upward movement of the grinding wheel assembly 33 can cause the coarse grinding wheel 33.1, fine grinding wheel 33.2, polishing wheel 33.3 and chamfering wheel 33.4 to detach from the glass.

[0022] like Figure 2 and 3As shown, the grinding head assembly also includes a cooling mechanism 40 for cooling the grinding wheel assembly 33 during operation. The cooling mechanism 40 includes a support assembly 41, a sleeve 42, a connecting pipe 43, a connecting ring 44, a water receiving tray 45, a water spray nozzle 46, and a water pipe connector 47. The support assembly 41 includes an inner support ring 41.1 that movably sleeves the periphery of the main motor 31, and an outer support ring 41.2 that is sleeved and fixed to the periphery of the inner support ring 41.1 and fixed within a through hole. The sleeve 42 movably sleeves the main motor 31. The outer casing 42 is divided into an upper thin section and a lower thick section. The upper thin section protrudes from the bottom of the housing 10 and is sealed to the main motor 31 by a sealing ring. The lower thick section movably rests on the rib ring provided at the bottom of the inner support ring 41.1, so that the casing 42 is rotatably mounted in the support seat assembly 41. The connecting pipe 43 is fixed to the bottom of the casing 42, the connecting ring 44 is fixed to the bottom of the connecting pipe 43, and the water receiving tray 45 is fixed to the bottom of the connecting ring 44, so that the casing 42, the connecting pipe 43, the connecting ring 44 and the water receiving tray form a complete structure. The top and bottom of the connecting pipe 43 and connecting ring 44 are joined together to form a closed chamber that surrounds the grinding wheel assembly 33, allowing the connecting pipe 43, connecting ring 44, and water receiving tray 45 to rotate with the sleeve 42. The top of the connecting pipe 43 is fixed to the bottom of the sleeve 42 with screws, and the connecting ring 44 is fixed to the bottom of the connecting pipe 43 with screws. To facilitate cleaning the water receiving tray 45 and disassembling the grinding wheel assembly 33, the water receiving tray 45 is magnetically attached to the bottom of the connecting ring 44 for easy disassembly and assembly. The specific connection method is as follows: Multiple magnets 48 are fixedly arranged around the bottom surface of the connecting ring 44. The water receiving tray 45 is a magnetic metal tray and includes a top-opening disc body 45.1. The periphery of the top opening of the disc body 45.1 is turned outward to form a flange 45.2. The top surface of the flange 45.2 is provided with multiple blind holes. The flange 45.2 is mated and attached to the bottom surface of the connecting ring 44. The magnets 48 are mated with the blind holes one by one, so that the water receiving tray 45 is axially attracted and fixed to the connecting ring 44, and the water receiving tray 45 is circumferentially fixed to the connecting ring 44 so that it can rotate with the connecting ring 44.

[0023] like Figure 2 , 3 As shown in Figures 5 and 6, the top of the disc 45.1 is provided with an arc-shaped notch 45.11 connecting the closed chamber to the outside. The glass can be horizontally inserted into the closed chamber along the arc-shaped notch 45.11 and come into contact with the grinding wheel assembly 33 that reaches the edge grinding station. In order to avoid the top and bottom surfaces of the glass from touching the water receiving trays 45 on the upper and lower sides of the arc-shaped notch 45.11, the height of the arc-shaped notch 45.11 is set to be greater than the thickness of the glass. In order to avoid the edge of the glass from touching the water receiving trays 45 on the left and right sides of the arc-shaped notch 45.11, the curvature of the arc-shaped notch 45.11 is set to be no less than 180 degrees. In this way, when the glass is inserted into the arc-shaped notch 45.11 in the center, it will avoid the water receiving trays 45 in the upper, lower and left and right directions, thus preventing the glass from being damaged due to contact with the water receiving trays 45.

[0024] like Figure 2 and3 As shown, in order to further prevent the glass from touching the water receiving trays 45 on both sides of the arc-shaped notch 45.11, the water receiving tray 45 is connected to a servo mechanism 50 for driving the active water receiving tray 45 to actively adjust the angle of its arc-shaped notch 45.11. The servo mechanism 50 includes a servo motor 51, an active wheel 52, a driven wheel 53, and a transmission belt 54. The driven wheel 53 is sleeved on the outer periphery of the upper thin section of the sleeve 42 and fixed to the top of the lower thick section of the sleeve 42 by screws. The servo motor 51 is fixed on the inner side wall of the housing 10. The active wheel 52 is driven on the output shaft of the servo motor 51. The transmission belt 54 is wound around the active wheel 52 and the driven wheel 53. When the grinding wheel assembly 33 moves along the periphery of the glass, the servo motor 51 can simultaneously drive the sleeve 42, connecting pipe 43, connecting ring 44 and water receiving tray 45 to rotate. The time for the water receiving tray 45 to rotate one revolution is set to be the same as the time required for the grinding wheel assembly 33 to rotate one revolution around the glass, so that the water receiving tray 45 and the grinding wheel assembly 33 can rotate synchronously. The water receiving tray 45 actively adjusts the position of its arc-shaped notch 45.11 to accommodate the glass, so that the glass is always centered within the arc-shaped notch 45.11.

[0025] like Figure 3 As shown, the bottom surface of the connecting pipe 43 has an open arc-shaped cavity 43.1, the inner wall has a radially arranged outlet hole 43.2 that connects to the arc-shaped cavity 43.1, and the top surface has an axially arranged inlet hole 43.3 that connects to the arc-shaped cavity 43.1. The lower thicker section of the sleeve 42 has a first inner hole 42.1 that connects to the top and bottom and aligns with the inlet hole 43.3. The driven wheel 53 has a corresponding second inner hole 53.1 that connects to the top and bottom and aligns with the first inner hole 42.1. The outlet hole 43.2 The internal water passage is formed by the arc-shaped cavity 43.1, the water inlet hole 43.3, the first inner hole 42.1 and the second inner hole 53.1; the water nozzle 46 is located inside the arc-shaped notch 45.11, the water nozzle 45 is V-shaped and the water inlet end is inserted and fixed in the water outlet hole 43.2, and the water outlet end is tilted downward and aligned with the contact surface between the grinding wheel assembly 33 and the glass; a water pipe connector 47 is inserted and fixed at the top of the second inner hole 53.1, and the water pipe connector 47 can be connected to a water supply pump set outside the box 10 through a water pipe.
