A device for repairing large r-angles

Abstract

The invention provides an R corner too large size repairing device. The R corner too large size repairing device comprises a base plate and further comprises a product fixing assembly and a grinding wheel grinding assembly which are arranged on the base plate. The product fixing assembly comprises a product containing groove and a rotation disc which are arranged up and down and fixedly connected,and notches are formed in the four R corner positions of the product containing groove. The grinding wheel grinding assembly comprises at least two grinding wheel grinding pieces arranged at the twoR corner notches in the diagonal line direction of the product containing groove. Each grinding wheel grinding piece comprises a sliding rail, a sliding piece arranged on the sliding rail in a slidingmanner, a grinding wheel and a movable connecting piece, wherein the sliding rail is horizontally arranged on the base plate and is arranged towards the corresponding R corner notch in the length direction, the grinding wheel is arranged on the side, close to the corresponding R corner notch, of the sliding piece, and the movable connecting piece is used for adjusting the grinding thickness of the grinding wheel and making the grinding wheel tightly pressed on the corresponding product R corner. By means of the R corner too large size repairing device, the two R corners, in the diagonal linedirection, of a product can be repaired at the same time, repairing of R corners of multiple products can be achieved as well, and the qualification rate reaches up to 100%.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a device for repairing a large R angle. Background technique [0002] At present, the front and rear cover panels of mobile phones are mostly made of 3D glass. The glass panel of mobile phones basically uses hot bending technology in the molding process. The size of the R angle is too small and scrapped. Therefore, products with a large R angle need to be repaired by the R angle repair device until the R angle meets the requirements to reduce waste and improve production yield. [0003] Most of the existing R-angle repair devices have the following problems: only one R-angle can be repaired at the same time, and two R-angles cannot be repaired at the same time. [0004] The invention patent with the application number of 201210466874.7 discloses a grinding wheel R-angle corrector, which has a semicircular base, and two chutes are opened in the middle of the base, and a...

Problems solved by technology

[0003] Most of the existing R angle repair devices have the following problems: only one R angle can be repaired at the same time, and two R angles cannot be repaired at the same time

Although this invention can process the two sides and R angles of the glass workpiece to the required dimensional accuracy through the grinding wheel, it cannot repair the two sides or two R angles of the glass workpiece at the same time.

[0006] To sum up, there is an urgent need for a large-size R-angle repair device to solve the problem that two R-angles cannot be repaired at the same time in the prior art
