Mobile phone liquid crystal screen vertical edging surface adsorption device and using method thereof

Abstract

The invention discloses a mobile phone liquid crystal screen vertical edging surface adsorption device. The mobile phone liquid crystal screen vertical edging surface adsorption device comprises a supporting plate, a plurality of working holes are formed in the plane of the supporting plate and in communication with suction cups, negative pressure holes communicated with the working holes are formed in the adsorption surfaces of the suction cups, air suction holes are formed in the side face of the supporting plate and communicated with the multiple working holes, an annular groove set is formed in the end face, away from the suction cups, of the supporting plate, the annular groove set is provided with a base, a driving piece for driving the base to move in the contour direction of the annular groove set is arranged between the base and the annular groove set, a pushing piece is arranged on the base, the pushing end of the pushing piece is far away from the supporting plate in the direction perpendicular to the contour direction of the annular groove set along the pushing end of the pushing piece of the supporting plate, an extending strip is arranged at the pushing end of the pushing piece, and an edge grinding assembly for grinding the edge of a display screen is arranged at the tail end, far away from the pushing piece, of the extending strip. By the adoption of the arrangement, the vertical edging surface adsorption device has the advantages of being free of direct contact with the display screen and suitable for polishing mobile phone display screens of different sizes.

Description

technical field [0001] The invention relates to the technical field of display screen edging, in particular to an adsorption device for a vertical edging surface of a mobile phone liquid crystal screen and a method for using the same. Background technique [0002] The liquid crystal screen is based on the liquid crystal material as the basic component, and the liquid crystal material is filled between two parallel plates, and the arrangement of the molecules inside the liquid crystal material is changed by voltage, so as to achieve the purpose of shading and light transmission to display different shades and random arrangement. There is a uniform image, and as long as a three-color filter layer is added between two flat plates, a color image can be displayed. [0003] Most of the mobile phone display screens are LCD screens. Since the edges of the mobile phone display screens are relatively sharp, the edges of the liquid crystal display screens will be edged during the produ...

Problems solved by technology

[0004] Although the existing display screen grinding machine can polish the edge of the display screen, with the acceleration of the replacement of mobile phones, the size of the screen surface of the display screen is different. The stroke will increase, and at the same time, the circumscribed circle of the full rotation of the rotating display screen will increase, thereby increasing the use of space, and at the same time, the volume of the grinding machine used to polish the display screen will be relatively large, thereby increasing production costs and use space; and At the same time, when the display screen is clamped by clamping parts, it often causes direct contact with the display screen, which increases the chance of scratching the surface of the display screen.
