The technical problem to be solved in the present invention be to provide one kind can either carry out workpiece attrition process again can quickly to grinding
Disk carries out repairing, and principle easy to use it is simple, while the high grinding mechanism of the splendid repairing quality of repairing effect.
In order to solve this problem, the present invention proposes a kind of based on the accurate of image detection and abrasive disk surface self-grown
Repairing mechanism, including rectangle little shower nozzle, high power photographic head, two ball screws, abrasive disks, the rectangle little shower nozzle are arranged on the
On one ball screw, and radially at the uniform velocity move above abrasive disk, the rectangle little shower nozzle uniformly sprays the UV for being mixed with abrasive particle
Photocureable coating proceeds by growing certainly for grinding panel surface in grinding panel surface, and the rectangle little shower nozzle both sides also install two
Root UV light lamp tubes, the high power photographic head are arranged on the second ball screw, and radially every a period of time above abrasive disk
A mobile segment distance, shoots abrasive disk surface appearance and then analyzes abrasive disk surface smoothness, the square by image detection
Shape little shower nozzle carries out point compensation according to the region that the result of analysis is inadequate to flatness in sprinkling.
The abrasive disk surface self-grown is that uniformly sprinkling is covered in after grinding panel surface by a kind of UV photocureable coating, is shone
Light-initiated its solidification of UV is penetrated, so as to go out the grinding layer of one layer of uniform ground in abrasive disk superficial growth, its concrete operations is：First
