Description

Technical Field

[0001] The utility model relates to the field of mobile phone tempered glass processing equipment, and more specifically, to a coating device used for the production of mobile phone tempered glass. Background Art

[0002] Tempered glass coating for mobile phones refers to a thin film coated on the surface of the glass. Before leaving the factory, the mobile phone screen is usually covered with a protective film on the upper side of the screen. This can ensure that the screen is always separated from the outer casing during transportation, and the screen of the mobile phone can be protected even if it shakes during transportation.

[0003] A Chinese patent discloses a coating device for the production of tempered glass for mobile phones (publication number CN113977929A), which includes a base, side panels, a cross beam, an adsorption mechanism, a material tray, a pressing frame and a feeding mechanism. A side panel is welded to one end of the upper surface of the base, a cross beam is welded to the inner side of the top of the side panel, a material tray is fixed on the side panel, a pressing frame is arranged on the base, a suspension rod is fixed below the top of the cross beam, a rotating plate is arranged at the bottom end of the suspension rod, pull rods are inserted at both ends of the rotating plate, a pressing plate is fixed to the bottom end of the pull rod, and rubber suction cups are fixed at the four corners of the bottom of the pressing plate. The laminating device used in the production of tempered glass for mobile phones has a simple overall structure. The laminating can be performed without pinching the film by hand, thereby ensuring the cleanliness of the film. At the same time, the difficulty of laminating can be reduced, which helps to improve production efficiency. Mechanization is used instead of manual laminating, which saves time and effort. It has strong stability and is not prone to operating errors. It can effectively improve the qualified rate of finished products. Rubber suction cups are usually used in the process of transporting and moving tempered glass. However, the rubber suction cups have a small adsorption area, and adsorption marks are easily left on the glass screen during the adsorption process. After the adsorption and movement, the screen surface usually needs to be cleaned. Summary of the invention

[0037] A gas connecting pipe 27 is provided inside the fixed platform 8, and the negative pressure suction cup 26 inside the adsorption component 24 is connected to the negative pressure air pump 17 through the gas connecting pipe 27. The negative pressure air pump 17 draws air outward, so that the negative pressure suction cup 26 can generate negative pressure, thereby adsorbing the glass plate workpiece 1 on the lower side.

[0038] Working principle of the utility model: the glass plate workpiece 1 moves at a constant speed on the conveyor belt 2. When the glass plate workpiece 1 moves to the bottom of the fixed platform 8, the second electric push rod 15 is started to push the second connecting member 18 downward to move. The lifting sliding track 22 and the second sliding member 2201 can ensure that the second connecting member 18 is more stable when moving downward. When the adsorption member 24 on the lower side of the fixed platform 8 contacts the surface of the glass plate workpiece 1, the negative pressure air pump 17 is started. The negative pressure air pump 17 generates negative pressure on the negative pressure suction cup 26 on the lower side through the gas connecting pipe 27. When the connecting airbag 25 contacts the surface of the glass plate workpiece 1 on the lower side, a sealed environment is generated between the connecting airbag 25 and the surface of the glass plate workpiece 1, so that the glass plate workpiece 1 can be adsorbed and fixed. As the negative pressure of the negative pressure suction cup 26 increases, the connecting airbag 25 will be compressed upward. The spring can dynamically balance the negative pressure formed between the connecting airbag 25 and the glass plate workpiece 1, and can increase the overall area of ​​adsorption, effectively avoiding the problem that the traditional suction cup device has small adsorption area and large internal negative pressure during adsorption, resulting in residual adsorption marks on the surface of the glass plate workpiece 1. Among them, the third electric push rod 19 can control the vertical adjustment plate 14 to move forward and backward, and the first electric push rod 10 can control the horizontal movement of the first connecting member 9, so that the operator can match and position the adsorption position of the fixed platform 8. When the fixed platform 8 adsorbs and fixes the glass plate workpiece 1, the second electric push rod 15 raises the entire fixed platform 8, and then the hydraulic rod 5 can move the push-pull processing plate 301 to the lower side of the fixed platform 8, so that the glass plate workpiece 1 can be placed on the push-pull processing plate 301, which is convenient for subsequent processing.
