[0002] Tempered glass is a protective film for mobile phone screens. The thickness of this protective layer is only 0.1 mm. It can completely cover the original screen surface to prevent damage and scratches from external forces, and increase impact absorption.

[0003] According to a disclosed edge and corner grinding device for tempered film processing (publication number: CN213411451U), the above application provides power through a driving member.

The L rod 710 is fitted on the inner wall of the slide groove 713 and reciprocates, which will drive the push block 81 to slide back and forth on the outer wall of the swing rod 711.

[0024] The knocking mechanism 9 includes a transmission rod 91, a rubber rod 92, a steel ball 93, a transmission gear 94, and a rack 95; the transmission rod 91 is rotatably connected to the outer wall of the bent rod 85, the outer wall of the transmission rod 91 is fixedly installed with a rubber rod 92, and the end of the rubber rod 92 away from the transmission rod 91 is fixedly installed with a steel ball 93, and the outer wall of the steel ball 93 is attached to the outer wall of the dust hood 712. When the transmission rod 91 rotates, it cooperates with the rubber rod 92 to drive the steel ball 93 to repeatedly knock on the outer wall of the dust hood 712. The dust attached to the outer wall of the dust hood 712 can be shaken off by the steel ball 93 knocking on the outer wall of the dust hood 712. The outer wall of the transmission rod 91 is fixedly installed with a transmission gear 94, and the outer wall of the inclined rod 82 is fixedly installed with a rack 95, which is meshed with the transmission gear 94. When the transmission rod 91 moves back and forth, it cooperates with the transmission gear 94 and the rack 95 to make it rotate back and forth on the outer wall of the bent rod 85.

[0025] Working principle: start the motor 3 to drive the shaft 4 to rotate. When the shaft 4 rotates, it will drive the grinding wheel 5 to rotate at high speed. The corners of the tempered film can be polished by the rotation of the grinding wheel 5. At the same time, start the industrial vacuum cleaner 6. When the industrial vacuum cleaner 6 is running, it can cooperate with the hose 714 and the dust cover 712 to absorb the dust and debris generated by the grinding of the tempered film to prevent the dust and debris from splashing and affecting the work of the staff. At the same time, it can also prevent the debris from scratching the tempered film. At the same time, the rotation of the shaft 4 will drive the driving gear 76 to rotate synchronously. When the driving gear 76 rotates, it can cooperate with the toothed disc 74 meshing with it to drive the rotating rod 71 to rotate on the outer wall of the column 2. At the same time, the toothed disc 74 will drive the eccentric rod 75 to make a circular motion around the rotating rod 71. While the eccentric rod 75 makes a circular motion around the rotating rod 71, it will reciprocate on the inner wall of the through groove 77. At the same time, the eccentric rod 75 will push and pull the T-shaped rod 72 back and forth, so that the T-shaped rod 72 slides back and forth on the inner wall of the column 2. While the T-shaped rod 72 slides back and forth, it will push and pull the connecting rod 78 back and forth, so that the connecting rod 78 drives the sliding block 79 to slide back and forth on the inner wall of the column 2. While the sliding block 79 slides back and forth on the inner wall of the column 2, it will drive the L-rod 710 to move back and forth synchronously up and down. At the same time, the L-rod 710 will fit the inner wall of the slide groove 713 and move back and forth and push and pull the swing rod 711 back and forth, so that the swing rod 711 rotates back and forth on the outer wall of the support plate 73. While the swing rod 711 rotates back and forth, it will drive the dust hood 712 to swing back and forth up and down on the side of the grinding wheel 5. The dust collection range of the dust collection hood 712 can be expanded through the up and down reciprocating swing of the dust collection hood 712, so that the dust collection hood 712 can fully absorb the dust floating on both sides of the grinding wheel 5, thereby improving the dust removal effect and effectively preventing dust and debris from splashing.

[0026] When the L rod 710 is fitted on the inner wall of the slide groove 713 and moves back and forth, it will drive the push block 81 to slide back and forth on the outer wall of the swing rod 711. When the push block 81 slides back and forth, it will drive the inclined rod 82 to move back and forth synchronously. When the inclined rod 82 moves back and forth, the limit groove 83 will reciprocate and squeeze the bent rod 85, so that the bent rod 85 drives the scraper 84 to slide back and forth on the inner wall of the dust collecting cover 712. When the scraper 84 slides back and forth, it will scrape off the dust attached to the inner wall of the dust collecting cover 712, so as to prevent the dust from accumulating on the inner wall of the dust collecting cover 712 and affecting the dust collection effect of the dust collecting cover 712. At the same time, as the scraper 84 slides back and forth on the inner wall of the dust hood 712, it will drive the fixed plate 86 to move back and forth synchronously, and as the fixed plate 86 moves back and forth, it will drive the push rod 87 to move back and forth synchronously. When the fixed plate 86 drives the push rod 87 to enter the interior of the hose 714, the push rod 87 will squeeze the dust and debris attached to the inner wall of the hose 714, thereby clearing the connection between the hose 714 and the dust hood 712, preventing dust and debris from getting stuck at the connection between the hose 714 and the dust hood 712 and causing the hose 714 to be blocked.

[0027] The bent rod 85 drives the scraper 84 to slide back and forth on the inner wall of the dust collecting hood 712, and at the same time drives the transmission rod 91 to move back and forth synchronously. The reciprocating movement of the transmission rod 91 drives the transmission gear 94 to move back and forth synchronously. The reciprocating movement of the transmission gear 94 cooperates with the rack 95 meshing with it to drive the transmission rod 91 to rotate back and forth on the outer wall of the bent rod 85. The reciprocating rotation of the transmission rod 91 drives the rubber rod 92 to rotate synchronously. The rubber rod 92 drives the steel ball 93 to repeatedly knock on the outer wall of the dust collecting hood 712 while rotating. The steel ball 93 knocking on the outer wall of the dust collecting hood 712 can shake off the dust attached to the outer wall, so that the dust collecting hood 712 can absorb the dust, thereby further improving the dust removal effect.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
