Description

Technical Field

[0001] This utility model belongs to the field of glass cover grinding technology, and in particular relates to a glass cover grinding device. Background Technology

[0002] Glass cover polishing equipment is used for precision processing of glass surfaces and is commonly found in the manufacturing processes of electronic products such as mobile phones, tablets, and automotive displays.

[0003] Traditionally, glass cover plates are fixed in place using clamps before being polished. While this method uses rubber pads on the clamps to protect the glass cover plate, it is difficult to control the clamping force during the process. Excessive clamping force can still cause the glass cover plate to crack, resulting in economic losses. Therefore, we propose a glass cover plate polishing device. Utility Model Content

[0004] The purpose of this invention is to provide a glass cover plate grinding device. By setting a fixing component, specifically, multiple glass cover plates are placed on multiple placement platforms. Then, a Roots pump is started to draw air out of the annular groove through a connecting pipe, thereby creating a negative pressure. At this time, the glass cover plates are adsorbed and fixed on the placement platforms. This method can quickly and simultaneously fix multiple glass cover plates, while preventing the glass cover plates from breaking. It solves the problem that in traditional glass cover plate grinding, the glass cover plates are usually fixed by clamps, which makes it difficult to control the clamping force during the clamping process, and easily leads to the glass cover plates breaking.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a glass cover grinding device, comprising a base, a grinding box mounted on the top of the base, an electric push rod mounted on the top of the grinding box, and further comprising:

[0058] One specific application of this embodiment is:

[0059] In use, first connect the delivery pipe through the inlet pipe 13 to add glass polishing liquid to the storage tank 21. After adding, place the glass cover plate on the placement platform 241. The positioning block 244 positions the glass cover plate, and the rubber sealing gasket 243 contacts the glass cover plate. Then, place multiple glass cover plates in sequence. After placement, start the Roots pump 15 to suck out the air in the annular groove 222 through the connecting pipe 151, thereby creating a negative pressure. The annular groove 222 is connected to the groove opening 242. At this time, the glass cover plate is adsorbed and fixed on the placement platform 241, and the rubber sealing gasket 243 is used to seal, so that the glass cover plate can be stably fixed on the placement platform 241. This method can quickly and simultaneously fix multiple glass cover plates, while preventing the glass cover plates from breaking. After multiple glass cover plates are fixed, start the electric push rod 224 to drive the annular groove 222 downward. The device moves so that the placement tray 221 is immersed in the glass polishing liquid in the storage tank 21, and the glass cover plate is adhered to the liquid. Then, the electric push rod 224 is activated to drive the placement tray 221 to return to its original position. At this time, the motor 236 is started to drive the turntable 234 to rotate, and the velvet polishing disc 235 rotates along with it. The electric push rod 12 is activated to drive the lifting seat 231 to move downward. The stabilizing rod 232 slides on the vertical rod 233 to make the movement of the lifting seat 231 more stable, and the velvet polishing disc 235 moves downward along with it. When the velvet polishing disc 235 contacts the glass cover plate, the polishing work can be carried out. The use of glass polishing liquid can improve the polishing effect. After the polishing is completed, the electric push rod 12 is activated to drive the lifting seat 231 to move upward to return to its original position, and the motor 236 is stopped. Then, the Roots pump 15 is started to release the negative pressure, thereby releasing the fixation of the glass cover plate. Finally, the staff can take out the glass cover plate.

[0060] When the velvet polishing disc 235 needs to be replaced after prolonged use, the locking nut on the threaded shaft 237 is removed to release the velvet polishing disc 235 from its fixation. Then, the velvet polishing disc 235 is pulled downwards to disengage the elastic plate 252 from the turntable 234, thus completing the disassembly. The new velvet polishing disc 235 is then inserted into the turntable 234. At this time, the insert block 251 drives the elastic plate 252 into the turntable 234. When the elastic plate 252 moves to the top of the turntable 234, it will elastically reset, thereby fixing the velvet polishing disc 235 to the bottom of the turntable 234 and providing support for the velvet polishing disc 235. At the same time, the threaded shaft 237 is also inserted into the turntable 234. Then, the operator can install the locking nut on the threaded shaft 237 to fix the velvet polishing disc 235 onto the turntable 234, thus completing the replacement work. This method eliminates the need for continuous support of the velvet polishing disc 235 during installation, making subsequent locking easier.
