LCD screen backplane leveling mechanism for electronic products

Abstract

The invention discloses a liquid crystal display backboard flattening mechanism used for electronic products. A supporting board of the liquid crystal display backboard flattening mechanism is located between a left guide rail base and a right guide rail base. A vertical air cylinder located under the supporting board is installed on a baseboard, and ejector rods of the vertical air cylinder are connected with the supporting board. The upper surface of the supporting board is covered with an elastic rubber mat. The left guide rail base and the right guide rail base are provided with a left through hole strip and a right through hole strip correspondingly. A rolling shaping rod is located above the supporting board, and the two ends of the rolling shaping rod are embedded into the left through hole strip and the right through hole strip correspondingly. The left end and the right end of a connecting shaft are sleeved with an upper left rolling bearing and an upper right rolling bearing correspondingly. The upper left rolling bearing is located between the connecting shaft and the left guide rail base, and the upper right rolling bearing is located between the connecting shaft and the right guide rail base. A lower left rolling bearing and a lower right rolling bearing are each composed of an inner bearing, an outer bearing and a bearing sleeve. According to the liquid crystal display backboard flattening mechanism used for the electronic products, the flattening effect is good, the flattening efficiency is high, the products are stable in quality and not liable to be broken, and flattening operation aiming to backboards of various thicknesses can be achieved.

Description

Technical field [0001] The invention relates to the processing field of liquid crystal screen backplanes, in particular to a leveling mechanism for liquid crystal screen backplanes used for electronic products. Background technique [0002] At present, the backplanes of electronic product display screens are mostly thin-plate stamping parts. In actual production, the flatness requirements of thin-plate stamping parts are higher, and the flatness is more bad, which seriously affects the product yield. For products with complex processes, the finished product is scrapped due to flatness. Seriously affect the company's efficiency and waste social resources. Therefore, flatness correction is required for defective flatness products. [0003] Technical shortcomings: Fixing the defective flatness products of the jig can only correct the defective products with a certain range of flatness values ​​each time. For the correction of multiple defective products with different flatness values...

Problems solved by technology

[0003] Technical disadvantages: The jig corrects the defective products with flatness. Each adjustment can only correct the defective products with a certain range of flatness values. For the correction of defective products with different flatness values ​​in different ranges, the jig needs to be adjusted.
