detailed description

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the implementation modes are not limitations of the utility model. Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figures 1 to 4, a backlight dust removal device provided by the utility model includes a frame 1 and a jig 4 for placing the backlight, and also includes a dust suction mechanism 3 and The dust removal mechanism 2, the jig 4 is located below the dust removal mechanism 2; the frame 1 includes two brackets 11 respectively arranged on both sides of the jig 4 and a support horizontal block 12 connected with the two brackets 11; The dust removal mechanism 2 includes a moving seat 22, a blowing part 21 arranged on the moving seat 22, and a displacement driving mechanism 23 for driving the displacement of the moving seat 22. The displacement driving mechanism 23 is arranged on the supporting horizontal block 12 and drives The blowing part 21 moves above the jig 4 ; the dust suction mechanism 3 is connected with the bracket 11 on the blowing side of the blowing part 21 .

In the detection process of the backlight source, it is necessary to keep the surface of the backlight source clean in order to reduce the impact on its detection and improve the accuracy of detection. In practical application, the jig 4 with the backlight placed on it moves to the bottom of the dust removal mechanism 2 through a mechanical mechanism, and then the displacement drive mechanism 23 drives the blower unit 21 to blow and remove the dust from the backlight placed on the jig 4. The dust and other pollutants blown off the surface of the backlight will be scattered in the air. In order to prevent some residual pollutants from falling on the backlight again, the dust suction mechanism 3 is used to absorb the pollutants blown off the surface of the backlight. , so as to ensure the cleaning effect on the back of the backlight, keep the backlight clean, and facilitate the subsequent detection process of the backlight.

In this embodiment, the blowing component 21 includes an air duct 211 and an air knife 212 , and the air knife 212 is installed on the air duct 211 .
