Description

Technical Field

[0001] The utility model belongs to the technical field of projectors and relates to a grinding device, in particular to a grinding device used for processing a projector lens cover. Background Art

[0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to computers, VCDs, DVDs, BDs, game consoles, DVs, etc. through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools, and entertainment venues. Depending on the working mode, there are different types such as CRT, LCD, and DLP. When the projector is in use, its lens will be equipped with a lens cover to protect the lens. During the production and processing of the lens cover, its edge needs to be polished.

[0003] After searching, it is found that a polishing device for processing a projector lens cover is disclosed in a Chinese patent document [Application number: 202122426123.X; Publication number: CN 215748240 U]. This polishing device for processing a projector lens cover includes a polishing box with a circular block inside, a lens cover is sleeved on the circular block, a cleaning mechanism is provided inside the polishing box, and the cleaning mechanism includes a fixed ring, a connecting rod, a plurality of bristles, a sponge block and a connecting pipe. The bottom end of the fixed ring is fixedly connected to the connecting rod, and the bottom end of the connecting rod is fixedly connected to the polishing box. One end of the plurality of bristles is embedded in the inner wall of the fixed ring, and the inner wall of the fixed ring is fixedly connected to the bottom end of the sponge block. The bristles and the sponge block lens cover are in contact with each other, and the connecting pipe is fixedly inserted into the back of the polishing box. The utility model utilizes the mutual cooperation of the circular block, the fixing ring, the connecting rod, the bristles, the sponge block and the connecting pipe. Water is passed into the connecting pipe, the bristles brush the lens cover, and the sponge block wipes the lens cover, which is beneficial to cleaning the debris when the lens cover is polished, saving working time and improving working efficiency.

[0004] Although this patent is helpful for cleaning debris when grinding the lens cover, this patent can only grind a single lens cover each time, resulting in low processing efficiency. In addition, when taking the lens cover after processing, it is necessary to manually rotate the screw to make the clamping block out of the limit state, which is cumbersome and does not save time and labor, affecting the overall use efficiency. Utility Model Content

[0005] The purpose of the utility model is to address the above-mentioned problems in the existing technology and to propose a grinding device for projector lens cover processing. The technical problem to be solved by the utility model is: how to grind multiple lens covers at the same time and automatically eject the processed lens covers.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

A wear-resistant plate is fixed to the output end of the servo motor, and the bottom surface of the wear-resistant plate is provided with anti-slip patterns.

[0014] With the above structure, the wear-resistant plate can be pushed to contact the lens cover by the electric push rod, and then the wear-resistant plate can be driven to rotate by the servo motor, thereby further driving the lens cover to rotate in the placement slot. During the rotation process, the surface of the lens cover is continuously rubbed by the brush layer, and the burrs on the surface are polished.

[0015] A storage groove is provided in the grinding frame, a grinding plate is slidably connected in the storage groove, a grinding block is fixed on the bottom surface of the grinding plate, a pair of threaded holes connected to the storage groove are vertically provided on the grinding frame, and screws are threadedly connected in the threaded holes, and the bottom end of the screw presses against the grinding plate.

[0034] By adopting the above structure, the driving motor 11 can be used to drive the driving gear 12 to rotate. After the driving gear 12 rotates, it will mesh with the driving gear 2 14 to drive the driving gear 2 14 to rotate. After the driving gear 2 14 rotates, it will drive the driving rotating rod 13 that is coaxially fixed to rotate. The driving rotating rod 13 then drives the driving bevel gear 15 to rotate through the coaxial fixed connection with the transmission bevel gear 15.

At this time, the electric push rod 18 pushes the wear-resistant plate 20 to contact the lens cover, and then the servo motor 19 drives the wear-resistant plate 20 to rotate, thereby further driving the lens cover to rotate in the placement groove 6. During the rotation of the lens cover, the surface is continuously rubbed by the brush hair layer, and the burrs on the surface are polished. At this point, the polishing work is completed, and then the conveying rack 4 is moved out of the grinding rack 2. At this time, the hydraulic push rod 9 can push the ejection block 10, and then the processed lens cover can be ejected through the ejection block 10, so that it is convenient for personnel to take it.
