Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a display positioning pressing plate tooling table. Background Art

[0002] The main body of the display includes the screen, backlight and screen display electronic control board. In order to ensure the service life of the display, dust cannot enter the inside of the display. Due to changes in the use environment, it cannot be guaranteed that dust impurities will not enter the inside of the screen, especially granular dust. Entering the inside of the screen can easily cause local punctures, and it is very easy to cause the screen to break after being compressed. It will also block the light source and cause uneven screen brightness. In order to ensure the service life of the display, when the electronic control board is loaded on the back panel of the display, sealants or sealing rings must be set at the joints to ensure that air dust does not enter the machine. When using sealants for bonding, a certain pressing force needs to be applied to the screen display electronic control board to ensure that the adhesive is expanded and all surrounding gaps are blocked. The entire display needs to be positioned before pressing, so it is necessary for us to design a positioning fixture. Utility Model Content
