Description

Technical Field

[0001] The present invention particularly relates to a pressure maintaining device for an automated light bar of a display. Background Art

[0002] E-LED light strips are attached to the side of the back panel, also known as edge-entry backlights, and are primarily used in displays. After the light strips are attached to the back panel's side flange using adhesive, they need to be held in place by applying pressure for a period of time.

[0003] The existing method of maintaining pressure is to manually operate the jig so that the jig keeps pressing the light bar for a period of time after being stressed, from placing it in the back panel to operating the jig to press the light bar, and finally squeezing the jig continuously by hand grip to achieve continuous pressure maintenance after the light bar is stressed. The whole process requires manual operation, which is troublesome and time-consuming, and has high labor costs. In addition, the manual pressure application makes the light bar pressure uneven and unstable. Therefore, we propose a pressure maintaining device for automatic light bar of display.

The air pump 403 is arranged at one end of the upper surface of the base plate 1, and one end of the air pump 403 is connected to an electro-pneumatic reversing valve 404 for adjusting the gas flow through a first pipe. The electro-pneumatic reversing valve 404 is connected to the lifting cylinder 401 through a second pipe, which facilitates the lifting of the connecting plate 5 by the lifting cylinder 401.

[0035] Preferably, two lifting cylinders 401 are provided, and the two lifting cylinders 401 are symmetrically arranged at both ends of the connecting plate 5, so as to better drive the connecting plate 5 to rise or fall.

[0036] Preferably, the clamping assembly 8 includes a clamping cylinder 801, a telescopic rod 802, a connecting block 803 and a slide 804. The slide 804 is slidably installed on the inner side of the connecting plate 5, and one end of the slide 804 is fixed to the pressure maintaining plate 7. The clamping cylinder 801 is installed on the slide 804 through the connecting block 803, and one end of the clamping cylinder 801 cooperates with the connecting plate 5 to facilitate driving the pressure maintaining plate 7 to move left and right.

[0037] Preferably, the slide plate 804 is rectangular, and a sliding groove corresponding to the slide plate 804 is opened through the inner side of the connecting plate 5 to facilitate better horizontal movement of the pressure maintaining plate 7.

[0043] The working principle and usage process of the present invention are as follows: when in use, the back plate 2 is placed on the base plate 1, and the back plate 2 is positioned by two positioning blocks 3. Then the lifting cylinder 401 drives the connecting plate 5 to descend through the fixing plate 402, and the telescopic rod 802 contracts and enters the inner side of the clamping cylinder 801, thereby driving the pressure-maintaining plate 7 to move. The pressure-maintaining plate 7 presses the light strip to be tightly attached to the inner wall of the back plate 2, and maintains pressure for a period of time. After maintaining pressure, the telescopic rod 802 extends from the inner side of the clamping cylinder 801, and then the lifting cylinder 401 drives the connecting plate 5 to rise, and the back plate 2 can be replaced. This cycle is repeated to maintain pressure on multiple light strips.
