Problems solved by technology

[0002] The LCD liquid crystal display needs to detect its own strength during production. The traditional method is manual detection, that is, the display screen to be tested is placed under the pressing device, and the display screen is taken out after the pressing device performs the pressing operation. This method exists The problem of relatively low detection efficiency, and subject to the problem of detection efficiency, manual inspection cannot detect large quantities of display screens one by one, and can only conduct random inspections, resulting in some of the produced display screens entering the market without inspection, and there are quality risks

Embodiment 1

[0020] see Figure 1-4 , the present embodiment provides a pressure-resistant detection device for LCD liquid crystal display production, including a workbench 3 . The upper part of the workbench 3 is provided with a display screen pressing assembly and a display screen conveying assembly. The display screen conveying assembly includes driven pulleys 6 which are respectively rotatably installed on both sides of the workbench 3 and driving pulleys 14 which are rotatably installed below the workbench 3. The two groups of driven pulleys 6 and the drive pulleys 14 are connected by transmission The belt 5 is sleeved and connected. Drive pulley 14 one sides are equipped with gear 9. The display screen pressing assembly controls the gear 9 to rotate intermittently through the transmission assembly.

[0021] Support legs 4 are installed at the bottom of the workbench 3 . The display pressing assembly includes a bracket 2 fixedly connected to the side of the workbench 3 . The supp...

Embodiment 2

[0033] see figure 1 , a pressure-resistant detection device for LCD liquid crystal display production. Compared with Embodiment 1, the side of the bracket 2 is fixedly connected to the workbench 3 through several connecting rods 13 arranged at intervals. One end of the driving rod 10 away from the pressing plate 12 passes between the connecting rods 13 and cooperates with the gear 9 to facilitate the up and down movement of the driving rod 10 .

[0034] In the embodiment of the present invention, through the setting of two sets of driven pulleys 6 and the driving pulley 14, the transmission belt 5 forms a triangular structure, and the driving pulley 14 is driven to rotate intermittently by using the up and down movement of the display screen pressing assembly, thereby realizing the transmission of the transmission belt. The intermittent operation of 5 not only realizes the continuous feeding of the display screen, but also provides stable conditions for the pressing operation ...

Abstract

The invention provides a pressure-resistant detection device for production of LCD liquid crystal display screens, and belongs to the technical field of LCD display screen production, and the device comprises a worktable, wherein the upper part of the worktable is provided with a display screen pressing component and a display screen conveying component, the display screen conveying component comprises driven pulleys rotatably installed on both sides of the worktable respectively and a driving pulley installed under the worktable, and the two sets of driven pulleys and the driving pulley are sleeved and connected through a transmission belt. In the embodiment of the invention, the transmission belt is formed into a triangular structure by the arrangement of the two sets of driven pulleys and the driving pulley, and the driving pulley is intermittently rotated by the up and down movement of the display screen pressing component to achieve intermittent operation of the transmission belt,which can detect large-scale display screens sequentially, has the advantage of high detection efficiency, prevents the undetected display screens from entering the market and improves the productionquality of the display screens.
