DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figures 1 to 8 In an embodiment of the present invention, a grinder includes a frame 1, a clamping mechanism 2 and a grinding mechanism 3. The frame 1 includes two support plates 11 spaced apart in the transverse direction, a bearing platform 12 is provided between the two support plates 11, the clamping mechanism 2 includes a bearing frame 21, the bearing frame 21 is arranged on the top of the bearing platform 12, a vertical driving member 22 is provided at the bottom of the bearing platform 12, the telescopic end of the vertical driving member 22 is connected to the bearing frame 21, a longitudinal driving member 23 is provided on the bearing platform 12, a material tray 24 is provided on the movable end of the longitudinal driving member 23, a plurality of rotating driving members 25 are arranged at intervals along the longitudinal direction in the material tray 24, a turntable 26 is provided on the output end of the rotating driving member 25, a plurality of clamps 27 are provided on the top of the turntable 26 along its circumference, and the grinding mechanism 3 is arranged between the two support plates 11 and is located above one of the turntables 26.

[0028] In this embodiment, there are two turntables 26 and rotating drive members 25, the vertical drive member 22 is an oil cylinder, an air cylinder or an electric cylinder, and the rotating drive member 25 is an electric rotating platform. When in use, the staff clamps the tempered film on the clamp 27 of each turntable 26, and then drives the material tray 24 to move longitudinally and vertically under the drive of the vertical drive member 22 and the longitudinal drive member 23, so that each turntable 26 is alternately moved to the polishing mechanism 3 for polishing. During the polishing process, the rotating drive member 25 drives the turntable 26 to rotate, so that each tempered film can be evenly polished. When polishing the tempered film on one of the turntables 26, the staff can re-clamp the tempered film on the other turntable 26. In this way, downtime can be reduced, the process can be smoother, and the polishing efficiency can be improved.

[0029] The longitudinal driving member 23 includes two slide rails 231 spaced apart in the transverse direction, a slide table 232 is slidably arranged on the top of the two slide rails 231, and the material tray 24 is arranged on the slide table 232. A driving wheel 233 and a driven wheel 234 are rotatably arranged in the two slide rails 231. The driving wheel 233 and the driven wheel 234 are spaced apart in the transverse direction, and a transmission belt 235 is sleeved between the driving wheel 233 and the driven wheel 234. The transmission belt 235 has a disconnected structure, and the starting end of the transmission belt 235 is connected to one side of the slide table 232, and the end of the transmission belt 235 is connected to the other side of the slide table 232. A transmission rod 236 is coaxially connected between the two driving wheels 233, and a first driving motor 237 is connected to one of the driving wheels 233. It can be understood that when the longitudinal drive member 23 is operating, the first drive motor 237 drives one of the driving wheels 233 to rotate, and under the transmission of the transmission rod 236, drives the other driving wheel 233 to rotate. The rotation of the two driving wheels 233 pulls the slide 232 along the slide rail 231 through the transmission belt 235, thereby driving the material tray 24 to move longitudinally.

[0030] The clamp 27 includes a bottom plate 271, and the top of the bottom plate 271 is provided with two side plates 272 spaced apart in the longitudinal direction, a fixed clamping plate 273 spaced apart in the transverse direction, and a movable clamping plate 2710, and the movable clamping plate 2710 can be moved away from or close to the fixed clamping plate 273, and a clamping space is limited between the bottom plate 271, the side plates 272, the fixed clamping plate 273 and the movable clamping plate 2710, and a push-out member 274 is provided on the top of the bottom plate 271 on one side of the movable clamping plate 2710. When in use, the staff stacks multiple tempered films in the clamping space in a transverse direction, and then pushes the movable clamping plate 2710 to move toward the fixed clamping plate 273 to press against the tempered film through the push-out member 274, so that the tempered film can be clamped in the clamp 27.

[0031] A slide groove 275 is provided on the top of the bottom plate 271 in the horizontal direction, and a slider 276 is provided on the bottom of the movable clamping plate 2710, and the slider 276 is slidably arranged in the slide groove 275. The arrangement of the slide groove 275 and the slider 276 can guide the movable clamping plate 2710 to prevent the movable clamping plate 2710 from deflecting when moving.

[0032] The fixing plate 273 is provided with a fixing hole 277, through which a bolt 278 is passed, and the top of the bottom plate 271 is provided with a plurality of threaded holes 279 spaced laterally, through which a bolt 278 passes and is screwed into one of the threaded holes 279. When in use, the installation position of the fixing plate 273 can be adjusted according to the number and size of the tempered films to be polished, thereby adjusting the volume of the clamping space and increasing practicality.

[0033] The push-out member 274 includes a rotating rod 2741 and a fixed block 2742. The fixed block 2742 is arranged on one side of the movable splint 2710. The rotating rod 2741 is rotatably arranged between the fixed block 2742 and the movable splint 2710. A push plate 2743 is provided on the surface of the rotating rod 2741. A first contact block 27410 is provided on the side of the movable splint 2710 away from the fixed splint 273. A second contact block 2744 is provided on the top of the fixed block 2742. The push plate 2743 can be in a first posture parallel to the central axis of the bottom plate 271 or a second posture intersecting the central axis of the bottom plate 271. When the push plate 2743 is in the first posture, the two ends of the push plate 2743 are respectively in contact with the first contact portion and the second contact portion. It can be understood that the push plate 2743 can be rotated by rotating the rotating rod 2741, so that the push plate 2743 can be switched between the first posture and the second posture. When the push plate 2743 is adjusted from the second posture to the first posture, the push plate 2743 can push the movable splint 2710 to move closer to the fixed splint 273. When the push plate 2743 is in the first posture, the movement of the movable splint 2710 can be restricted to prevent the movable splint 2710 from moving away from the fixed splint 273. When in use, the staff rotates the rotating rod 2741 to make the push plate 2743 is in the second posture, and then multiple tempered films are stacked horizontally in the clamping space. After putting in an appropriate amount of tempered films, the rotating rod 2741 is rotated to adjust the push plate 2743 to the first posture, thereby pushing the movable splint 2710 to move toward the fixed splint 273 to press against the tempered film. After polishing, the push plate 2743 is adjusted to the second posture by rotating the rotating rod 2741 to release the restriction on the movable splint 2710, and then push the movable splint 2710 to move away from the fixed splint 273, so that the tempered film can be removed.

[0034] The two ends of the push plate 2743 are provided with outwardly convex arc-shaped contact parts 2745, and the arc surfaces of the two arc-shaped contact parts 2745 face oppositely. When the push plate 2743 is adjusted from the second posture to the first posture, the two outwardly convex arc-shaped contact parts 2745 can contact the first contact block 27410 and the second contact block 2744 respectively, thereby pushing the movable clamping plate 2710 to move closer to the fixed clamping plate 273.

[0035] The upper end of the rotating rod 2741 is provided with a swing arm 2746, the end of the swing arm 2746 is provided with a mounting hole (not shown in the figure), an insertion rod 2747 is inserted into the mounting hole (not shown in the figure), a handle 2748 is provided at the upper end of the insertion rod 2747, and a plug hole 2749 for inserting the plug rod 2747 is provided at the top of the second contact block 2744. When in use, the staff can drive the rotating rod 2741 to rotate through the handle 2748, thereby driving the push plate 2743 to switch between the first posture and the second posture. When the push plate 2743 is in the first posture, the plug rod 2747 can be inserted into the plug hole 2749 to prevent the rotating rod 2741 from rotating, so that the push plate 2743 is always in the first posture, and the movable clamping plate 2710 is restricted.

[0036] The grinding mechanism 3 includes a mounting frame, on which four second drive motors 31 are arranged symmetrically in pairs, wherein grinding discs 32 are arranged on the rotating shafts of two second drive motors 31, and cleaning discs 33 are arranged on the rotating shafts of the other two second drive motors 31, and a plurality of cleaning strips 34 are arranged on the bottom surface of the cleaning disc 33, and the two grinding discs 32 are not on the same horizontal line, and the two cleaning discs 33 are not on the same horizontal line. During grinding, the grinding disc 32 is used to grind the side of the tempered film, and the cleaning disc 33 is used to sweep away the debris generated by grinding. During the grinding process, the turntable 26 rotates under the drive of the rotating drive member 25, so that the tempered film on the turntable 26 moves successively to the bottom of the grinding disc 32 and the cleaning disc 33 for grinding and cleaning.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
