Description

Technical Field

[0001] The utility model belongs to the technical field of glass coating, and particularly relates to a loading and unloading system for upper and lower positioning jigs of blue glass. Background Technique

[0002] In the field of optical glass processing and manufacturing, products need to be coated. Generally, the product needs to be placed in a fixture and fixed, and then the fixture is placed in a coating umbrella for coating processing. Because the tolerance between the fixture and the product is small, it is difficult to place the glass sheet, and the manual processing method has low efficiency. An automated device with high efficiency is needed.

[0003] Chinese patent document with publication number CN106239756A discloses an automatic loading and unloading method for a zero standby four-axis robot of an automated production line, which includes the following steps: (1) setting a four-axis robot, a suction cup, a processing position mechanism, a precision fixture, and a glass product placement mechanism that move synchronously with the workbench; (2) the four-axis robot sucks the glass to be processed from the glass product placement mechanism, places the glass to be processed on the precision fixture for precise positioning, and then places it in the processing position mechanism; (3) repeating step (2); (4) while the double-head precision engraving machine processes the glass to be processed in the processing position mechanism, the four-axis robot repeats steps (2) and (3) to place the other two pieces of glass to be processed in the processing position mechanism respectively; (5) the four-axis robot takes out the finished glass; (6) continuously repeating steps (2), (3), (4), and (5).

[0004] When applying the above technical solution to assemble the glass and the fixture, the four-axis robot needs to move the fixture and the glass successively, and the working efficiency is low. At the same time, because the gap between the glass and the fixture is very small, it also requires the four-axis robot to have extremely high positioning accuracy and extremely low repeat positioning error, but correspondingly, it also increases the manufacturing cost and control difficulty. During the assembly process, due to the existence of external factors such as mechanical vibration, and the weak deviation between the glass and the fixture and other factors will cause the failure of the assembly. Therefore, the above technical solution cannot meet the actual use requirements. Content of the Utility Model

[0005] In order to overcome the technical problems in the prior art that placing the glass and the fixture successively will lead to low assembly efficiency. At the same time, the gap between the glass and the fixture is small, requiring high-precision motion control in the assembly process, but this will increase the manufacturing cost and control difficulty. An object of the present utility model is to provide a loading and unloading system for a blue glass positioning fixture. By setting a turntable with multiple operating stations, each station can synchronously perform the loading and unloading of the glass and the fixture, improving the assembly efficiency. At the same time, structures for adjusting the positions of the glass and the fixture are respectively provided, reducing the motion precision of the moving mechanism, increasing the relative position precision between the glass and the fixture, and not increasing the cost and control difficulty of the moving mechanism.
