Embodiment 1

[0024] see figure 1 , a display screen shading tape attachment device, including a conveying rack 1, a transmission rack 2, a movable rack 3, a material rack 4 and a pneumatic rack 5, the top of the conveying rack 1 is installed with a conveyor belt 11, the conveyor belt A limiting device 12 is installed on the right side of 11, the material rack 4 is arranged on the side of the conveyor belt 11, a pneumatic rack 5 is installed on the top of the material rack 4, and a cylinder 51 is installed on the pneumatic rack 5, and the cylinder 51 A piston rod 52 is mounted on the bottom end, and a pressing plate 53 is mounted on the bottom end of the piston rod 52 .

[0025] During operation, the liquid crystal panel is placed on the conveyor belt 11 for an assembly line process. The limiting device 12 ensures the standardization of the position of the liquid crystal panel, and the air cylinder 51 drives the pressing plate 53 to move periodically, so as to squeeze and fit the shading ru...

Embodiment 2

[0031] This embodiment is a further optimization of Embodiment 1. Based on this, please refer to image 3 , the material rack 4 is respectively equipped with a feeding roller 40, a guide roller 41, a spreading plate 42, a primary direction changing roller 43, a secondary direction changing roller 48 and a receiving roller 49. The front end of the material frame 4 A convex plate 47 is installed, an elastic frame 45 is arranged above the convex plate 47 , and an elastic sheet 46 is installed at the bottom end of the elastic frame 45 , and the elastic sheet 46 fits with the convex plate 47 .

[0032] The guide rollers 41 are provided with two lanes and are located on the left and right sides of the material spreading board 42 respectively, and the guiding rollers 41 and the material spreading board 42 are located on the same horizontal line. A limiting block 44 is arranged between the guide roller 41 on the left side and the first-level direction changing roller 43, and a guide p...

Abstract

The invention relates to the field of LED display screens, in particular to a display screen shading tape attachment device, which includes a feeding frame, a transmission frame, a movable frame, a material frame and a pneumatic frame, and a conveyor belt is installed on the top of the feeding frame. The material frame is arranged on the side of the conveyor belt, the top of the material frame is equipped with a pneumatic frame, the pneumatic frame is equipped with a cylinder, the bottom end of the cylinder is equipped with a piston rod, and the bottom end of the piston rod is equipped with a pressing plate, The transmission frame is arranged on the left side of the conveyor belt, a top plate is installed on the top of the transmission frame, a guide rail is installed on the top plate, the movable frame is installed on the guide rail, and a straight rod is installed horizontally on the right end of the movable frame , the top of the straight rod is installed with a spacer frame through the movable shaft, and elastic gaskets are laid on the spacer frame. In the present application, through the cooperation of the crank connecting rod transmission and the secondary connecting rod transmission, the contact between the pressing plate and the liquid crystal panel can be avoided, thereby avoiding pollution on the surface of the liquid crystal panel.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to a display screen light-shielding tape attachment device. Background technique [0002] The reason why LED has been widely valued and developed rapidly is inseparable from its own advantages; these advantages are summarized as: high brightness, low operating voltage, low power consumption, large size, long life, impact resistance and The performance is stable; the development prospect of LED is extremely broad, and it is developing in the direction of higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability and full colorization. LED displays are widely used in sports venues, commercial applications, banks, securities, postal services, docks, shopping malls, stations, postal services, telecommunications, institutions, monitoring, schools, restaurants, hotels, entertainment, and other outdoor advertising. [0003] The Chinese...
