Document Type and Number:
WIPO Patent Application WO/2019/006840
Kind Code:
A1
Abstract:
Disclosed is an automatic abrasive paper switching mechanism for a pneumatic grinding and polishing machine. The mechanism comprises a new abrasive paper storage barrel (1) and a used abrasive paper unloading blade (2) located beside the new abrasive paper storage barrel (1), wherein a power source (6) for pushing abrasive paper upwards inside the new abrasive paper storage barrel (1) is arranged below the new abrasive paper storage barrel (1), and an upper end of the new abrasive paper storage barrel (1) is open. By providing the new abrasive paper storage barrel (1), the used abrasive paper unloading blade (2) and the power source (6) for pushing the abrasive paper upwards inside the new abrasive paper storage barrel (1), a robot moves a grinding and polishing head to be in front of the used abrasive paper unloading blade (2), and the robot moves slowly to tear off the used abrasive paper by the used abrasive paper unloading blade (2), and the robot then moves to a position right above new abrasive paper, and the power source (6) presses the abrasive paper onto the grinding and polishing machine, and then the robot moves away, thereby completing the adhesion of the new abrasive paper. The robot continues grinding and polishing, and when grinding and polishing are carried out a certain number of times, the above-mentioned actions are repeated. The automatic abrasive paper switching mechanism enables the automatic replacement of abrasive papers without manual operations, thus solving the safety risk in the prior art.
