Description

Technical Field

[0001] The utility model relates to the technical field of fixing equipment for liquid crystal display screen processing, and particularly provides a fixing device for liquid crystal display screen processing. Background Technique

[0002] A liquid crystal display screen is a display device that uses liquid crystal materials to control the passage of light and then display images. The liquid crystal itself does not emit light. It relies on a backlight source (such as an LED or CCFL) to illuminate the pixels, thereby forming a visible image. Due to its light weight, low energy consumption, and good display effect, liquid crystal display screens are widely used in various electronic devices such as televisions, computer monitors, mobile phones, and tablet computers.

[0003] After retrieval, the Chinese patent application number is: CN202010181922.2, which discloses an LED display screen test fixture, including a fixing frame, a left clamping plate, a right clamping plate installed on both sides of the inner wall of the fixing frame, and a detection platform for placing the LED display screen. Two groups of limit sliding grooves are opened on the upper surface of the fixing frame. A power connection port is arranged on the side surface of the fixing frame. A plurality of groups of springs and two groups of limit rods are respectively arranged on both sides of the inner wall of the fixing frame. An adjusting bolt is threadedly connected inside the threaded hole; a limit plate is fixed on the upper surface of the detection platform. Two groups of sliders slidably installed inside the limit sliding grooves are fixed on the lower surface of the detection platform. One end of each of the two groups of sliders is vertically fixed with a push rod. The LED display screen is fixed by moving the right clamping plate, so that the LED display screen is fixed between the left clamping plate and the right clamping plate. At the same time, a buffer mechanism composed of the spring and the left clamping plate avoids large deformation on one side of the LED display screen, thereby avoiding damage to the LED display screen.

[0004] When the above technical solution fixes the display screen, it is necessary to manually rotate the adjusting bolt to drive the left and right clamping plates to clamp and fix the display screen. Such a fixing method is too slow and inefficient for the production and processing of display screens. Moreover, it increases the labor and time costs for fixing the display screen during processing. Therefore, we need to propose a fixing device for liquid crystal display screen processing. Content of the Utility Model

[0031] It further includes a driving mechanism for driving the movement of the side plates 3; the driving mechanism includes a motor 9 and a driving block 11 mounted at the bottom of the base 2, the output end of the motor 9 is fixedly connected with a shaft rod 10 through a coupling, the shaft rod 10 extends above the base 2, the driving block 11 is located at the upper end of the shaft rod 10, two groups of driving arms 12 are arranged in a linear shape on both sides of the driving block 11, a connecting arm 13 is hinged at the end of the driving arm 12, and a convex block 14 is arranged on one side of the side plate 3, and the other end of the connecting arm 13 is hinged to the convex block 14.

[0032] By arranging the base 2 on the bracket 1, and arranging the fixing mechanism including the side plates 3 and the clamping blocks 4 on the base 2, the side plates 3 are slidably mounted on the base 2, the clamping blocks 4 are located at the tops of the side plates 3, and a clamping groove 5 is formed on one side of the clamping blocks 4, and a driving mechanism for driving the two groups of side plates 3 to approach or separate is also arranged.
