A device and method for eliminating bright edges of a panel light

Abstract

The invention discloses a device for eliminating bright edges of a panel light, which is suitable for the diffusion plate of the panel light, and is characterized in that it includes a linear conveying device, which includes a conveyor belt capable of driving a single diffuser plate to move and a belt located on the conveyor belt. There are two limit guide rails on both sides, and there are line-drawing mechanisms on both sides of the conveyor belt. The relative positions of the line-drawing mechanism and the corresponding side limit guide rails are fixed. Spray head. The advantage of the present invention is that the single diffuser plate moves linearly with the conveyor belt in the linear conveying device, and the limit guide rail limits the moving direction of the single diffuser plate and limits the edge of the diffuser plate. When the single diffuser plate passes under the spraying head, the spraying head sprays black liquid to complete the black edge spraying on the edge of the diffuser plate. The consistency of the edges is good.

Description

technical field [0001] The invention relates to the technical field of panel light production, in particular to a device and method for eliminating bright edges of a panel light. Background technique [0002] In the production process of LED lamps in the prior art, there are often bright edges on the side of the product LED panel lamp. The main reason is that the LED panel lamp is based on the principle of side light emission. For example, the authorized announcement number in the Chinese patent literature It is CN207893504U, and the authorized announcement date is September 21, 2018. The name is "a panel light in the form of upper and lower covers". This utility model discloses a panel light in the form of upper and lower covers, including an aluminum frame. The inner side of the surface frame is fixed with an LED light group with heat-conducting double-sided adhesive tape, the inner plane of the aluminum surface frame is equipped with a diffusion plate, the back of the dif...
