Description

Technical Field

[0001] The utility model relates to the technical field of LED diffusion plate processing, in particular to a positioning device for LED diffusion plate production. Background Art

[0002] LED diffuser can cause great interference to light. No matter how many degrees the original light distribution curve is, as long as the light passes through the diffuser, it will change the beam angle to 160~176°. The larger the beam angle, the lower the illumination. Therefore, the base material of the diffuser should be made of a material with a lower refractive index, and the interference to light will be lower. It is mainly used in various LED lamps. With the continuous development of the economy, people's demand for LED diffuser is also increasing. During the production process, the LED diffuser needs to be positioned by a positioning device before cutting. A Chinese patent discloses a positioning device for the production of LED diffusers (authorization announcement number CN211682370U). This patent technology discloses a positioning device for the production of LED diffusers. The positioning device for the production of LED diffuser plates includes an operating table; a moving component, the moving component is fixedly mounted on the top of the operating table; a crossbeam, the crossbeam is fixedly mounted on one side of the moving component; a lifting component, the lifting component is slidably mounted on the crossbeam; a cutting machine, the cutting machine is fixedly mounted on the bottom end of the lifting component; a rectangular through hole, the rectangular through hole is opened on the top of the operating table; a sliding block, the sliding block is slidably mounted in the rectangular through hole; two brackets, the two brackets are respectively fixedly mounted on the top of the operating table and the sliding block, and the brackets on the sliding block extend outside the rectangular through hole. The positioning device for the production of LED diffuser plates provided by the utility model has the advantages of being easy to use, simple to operate, easy to quickly position, low cost, and able to effectively improve production efficiency. This patented technology solves the problems that the design of the traditional positioning device for the production of LED diffuser plates still has shortcomings, such as its complex structure, cumbersome operation, high cost, slow positioning speed, and affecting production efficiency.
