[0030] The suspension seat 1 is used to be fixed on a movable slide of a grinding circuit of a grinding device, and the suspension seat 1 is also used to support the installation of other components.

[0031] The lifting mechanism 2 includes a lifting screw 21, a lifting nut 22, a guide rail 23, a lifting slide 24, and a third motor 25. The lifting screw 21 is vertically arranged and supported on the suspension base 1 at both ends by bearing seats. The lifting nut 22 is threadedly engaged with the lifting screw 21. The guide rail 23 is arranged on the suspension base 1 and is parallel to the lifting screw 21. In this embodiment, there are two guide rails 23, which are symmetrically arranged on both sides of the lifting screw 21. The lifting slide 24 is fixedly connected to the lifting nut 22 and slidably engages with the guide rails 23. The third motor 25 is arranged on the suspension base 1 and is transmission-connected to the upper end of the lifting screw 21. In this embodiment, the output shaft of the third motor 25 is connected to the upper end of the lifting screw 21 via a coupling. In this way, the third motor 25 can drive the lifting screw 21 to rotate, thereby driving the lifting slide 24 up and down through the lifting nut 22 to adjust the height position of the lifting slide 24.

[0032] The lifting slide 24 is provided with a mounting seat 5, which forms a cantilever structure with the lifting slide 24, and the middle of the mounting seat 5 is a hole for avoiding air. The mounting seat 5 can move up and down synchronously with the lifting slide 24.

[0033] A hollow rotating platform 6 is provided on the lower side of the mounting base 5. The hollow rotating platform 6 utilizes existing technology. A first motor 61 is provided on one side of the upper end of the hollow rotating platform 6. The lower end of the hollow rotating platform 6 serves as the load end. A guide rail seat 62 is provided on the load end of the hollow rotating platform 6. A clearance hole is also provided in the middle of the guide rail seat 62. A linear guide rail 63 is provided on each side of the lower surface of the guide rail seat 62. The first motor 61 can drive the guide rail seat 62 to rotate via the hollow rotating platform 6.

[0034] The grinding head drive mechanism 4 includes a clamp 41, a main shaft 42 and a second motor 43. The clamp 41 is arranged below the linear guide rails 63 and slides with the two linear guide rails 63. The second motor 43 is arranged on the upper side of the clamp 41 and is located on the inner side of the hollow rotating platform 6. The output shaft of the second motor 43 faces downward, and the upper end of the main shaft 42 is connected to the output shaft of the second motor 43 through a coupling.

[0035] The grinding head assembly 3 includes a handle 31, a rough grinding wheel 32, and a polishing wheel 33. The upper end of the handle 31 is detachably connected to the lower end of the spindle 42. The rough grinding wheel 32 and the polishing wheel 33 are disposed at the lower end of the handle 31, with their axes coinciding. A spacer may be provided between the rough grinding wheel 32 and the polishing wheel 33 to separate them. In this embodiment, the polishing wheel 33 is disposed below the rough grinding wheel 32.

[0036] The grinding head position adjustment mechanism 7 includes a first cylinder 71 and a second cylinder 72. The first cylinder 71 is supported on the side of the guide rail base 62 via a first support block 73. When the telescopic rod of the first cylinder 71 is extended, its front end contacts the side of the clamp 41, pushing the clamp 41 along the length of the linear guide rail 63. The second cylinder 72 is supported on the guide rail base 62 via a second support block 74, located on the opposite side of the first cylinder 71. When the telescopic rod of the second cylinder 72 is extended, its front end contacts the side of the clamp 41, pushing the clamp 41 toward the first cylinder 71. Protective pads can be provided at the front ends of the telescopic rods of the first and second cylinders 71, 72. These pads can be made of a flexible material to cushion the impact when the rods contact the clamp 41 and reduce any noise.

[0037] The second support block 74 is also provided with a limit member 75, which can be a limit screw. A threaded hole or a through hole is provided on the second support block 74, and the limit screw is fixed at the threaded hole or the through hole. The front end of the limit screw is located on the inner side of the second support block 74 and faces the first cylinder 71, and is at the same height as the side of the clamp 41. The number of limit screws can be set to two or more. The limit screw is used to limit the position of the clamp 41 moving toward the second cylinder 72, and at the same time work together with the first cylinder 71 to clamp the clamp 41.

[0038] The module also includes a protective cover 8, which covers the lifting mechanism 2, the grinding head assembly 3, the grinding head drive mechanism 4 and the grinding head position adjustment mechanism 7. The lower end of the protective cover 8 is an open end, and the coarse grinding wheel 32 and the polishing wheel 33 pass through the lower end of the protective cover 8. The setting of the protective cover 8 not only provides safety protection for the working mechanism inside, but also plays a dust-proof role.

[0039] An annular water spray pipe 81 is provided at the lower end of the protective cover 8. Water nozzles 82 are located on the underside of the annular water spray pipe 81. The water outlets of the water nozzles 82 are directed toward the rough grinding wheel 32 and the polishing wheel 33. Multiple water nozzles 82 are spaced apart along the circumference of the annular water spray pipe 81. Liquid flowing from the water nozzles 82 is sprayed toward the rough grinding wheel 32 and the polishing wheel 33, thereby cooling and lubricating the rough grinding wheel 32 and the polishing wheel 33 during grinding or polishing, thereby increasing the service life and polishing effect of the rough grinding wheel 32 and the polishing wheel 33.

[0040] The working principles of the edge grinding and flexible polishing mechanism of the glass processing center grinding head provided by the embodiment of the present invention are as follows:

[0041] During operation, the grinding wheel of the grinding head will rotate 360 ​​degrees along with the hollow rotating platform and then return to the origin. When the workpiece needs to be rough ground, the first cylinder 71 works, and the telescopic rod of the first cylinder 71 extends to push the clamp 41 toward the direction of the second cylinder 72, while driving the main shaft 42, the second motor 43 and the grinding head assembly 3 to move together. When the clamp 41 moves to be supported by the limiter 75, it stops moving. The first cylinder 71 and the limiter 75 work together to fix the clamp 41, and then move the suspension seat 1 to move the rough grinding wheel 32 close to the side of the workpiece. The second motor 43 can drive the rough grinding wheel 32 to rotate and grind the side of the workpiece. After the rough grinding is completed, the lifting mechanism 2 drives the mounting seat 5 to rise, so that the polishing wheel 33 corresponds to the side of the workpiece. At the same time, the telescopic rod of the first cylinder 71 is retracted, and the telescopic rod of the second cylinder 72 is extended to push the clamp 41 toward the direction of the first cylinder 71. 1 has no limit piece 75 on one side, and when the second cylinder 72 is working, the clamp 41 is not connected or abutted with other components on the side close to the first cylinder 71, so that the clamp 41 is in an active state. When the second cylinder 72 pushes the clamp 41 to move, it drives the polishing wheel 33 to press against the side of the workpiece and maintain a certain pressure. The polishing wheel 33 will continue to wear during the operation. Under the action of the control system and the second cylinder 72, the polishing wheel 33 and the side of the glass will always keep close contact with each other for polishing and maintain a certain pressure. When polishing different sides, the first motor 61 drives the guide rail seat 62 to rotate, so that the telescopic rod of the second cylinder 72 is always facing the processing surface, thereby ensuring that the second cylinder 72 presses the polishing wheel 33 to always contact the processing surface, so that every edge will not be missed and the polishing is stable.

[0042] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
