Description

Technical Field

[0001] The utility model relates to the technical field of tempered film production, in particular to a tempered film scanning machine. Background Art

[0002] Grinding and polishing technology is an important technical link in the field of modern workpiece surface processing. The surface roughness of the workpiece is reduced by grinding and polishing equipment to obtain a bright and flat surface. Tempered film is a very thin film made of tempered glass, which has the functions of wear resistance and explosion-proof, that is, ordinary glass is tempered. Most of the current mobile phone tempered films are manufactured to prevent the mobile phone screen from falling to the ground and being damaged. In order to meet the high requirements of the tempered glass film surface of smart phones for scanning transparency and texture during production, a scanning machine is used to grind and polish the tempered glass film during the processing of the mobile phone tempered film. The current scanning machine needs to use a special polishing fluid for polishing when working, but lacks a liquid circulation structure, and needs to manually add liquid, and cannot be fully automatically processed. In addition, there will be impurities in the polished liquid when it is recycled. Directly pouring it into the liquid for use will affect the grinding effect and the quality of the workpiece, greatly reducing the yield rate of the workpiece. Utility Model Content

[0019] The filter device 7 includes a filter housing 701, which is a hollow cavity structure. A sponge 704 is installed in the filter housing 701. The bottom of the filter housing 701 is a filter mesh structure 703. The top of the filter housing 701 has an end cover 702. The end cover 702 is fixedly installed with the first liquid inlet pipe 6, and the first liquid inlet pipe 6 is connected to the filter housing 701.

[0020] The feeding device 9 includes a support base 10, a suction cup 11 and a flipping drive mechanism for driving the suction cup 11 to flip. The flipping drive mechanism is installed on the support base 10. The surface of the suction cup 11 is provided with a plurality of vacuum adsorption holes for adsorbing the tempered film. The vacuum adsorption holes are externally connected to a vacuum generator for vacuum adsorption of the tempered film. The other side of the suction cup 11 is installed with the flipping drive mechanism. The flipping drive mechanism drives the suction cup 11 to flip toward the grinding disc 18. A second rotating motor 7 is installed on the suction cup 11 to drive the suction cup 11 to rotate.

[0021] The flipping drive mechanism includes a first driving shaft 12, a second driving shaft 13, a gear 14, a rack 15 and a lifting motor 16. The first driving shaft 12 is vertically connected to the second driving shaft 13, the other end of the second driving shaft 13 is fixedly connected to the suction cup 11, and the second driving shaft 13 is arranged in parallel with the suction cup 11. The two port positions of the first driving shaft 12 are rotatably connected to the support seat 10 through a mounting plate 17, and the mounting plate 17 is fixedly installed with the support seat 10. The gear 14 is fixedly installed on one side of the first driving shaft 12 and is coaxially installed with the first driving shaft 12.

An inwardly concave limiting hole is provided on the grinding table 2 corresponding to the position of the second driving shaft 13.

[0022] Working process: When the tempered film is adsorbed on the suction cup 11 by vacuum, the flipping drive mechanism drives the suction cup 11 to flip the direction of the grinding disc 18, so that the grinding disc 18 and the suction cup 11 are opposite to each other. At this time, the tempered film on the suction cup 11 is in contact with the grinding disc 18. At this time, the rotating motor is running, so that the grinding disc 18 and the suction cup 11 both start to rotate to polish the tempered film. At the same time, the first liquid inlet pipe 6 will flow out the polishing liquid through the filter device 7 and fall on the grinding disc 18. The polishing liquid can assist the grinding disc 18 in polishing the tempered film, and also play a cooling and lubricating role, so that the polishing quality of the tempered glass film is higher. At the same time, after the polishing liquid flows into the grinding disc 18, it can flow back to the first liquid outlet pipe 8 through the gap between the grinding disc 18 and the chamber 201, and then flow back to the water tank 4, waiting to flow in again for use, so the polishing liquid can be recycled to reduce production costs.

[0023] Compared with the prior art, the tempered film polishing machine of the present application has a compact layout, can recycle the polishing liquid, and does not require manual addition, thus reducing the time of manual operation. In addition, a filtering device is also provided in the feeding of the polishing liquid, which can better filter impurities in the polishing liquid, avoid cross-infection of the workpieces, and improve the yield rate of the workpieces.
