Problems solved by technology

Teaching: This requires a good consistency of the product and a very precise fixture; because the lens is an irregular surface, it is difficult to make a very precise fixture, resulting in a high defect rate and requiring a lot of post-processing rework
2D visual positioning: Since the lens is an irregular surface, 2D positioning can only determine the XY plane. Once there is an error in the Z direction, there will be a large deviation in the dispensing track, resulting in a high defect rate
[0003] Traditional curved lens dispensing cannot give precise positions. Once there is a slight difference in the lens or the fixture is not accurate, it will cause abnormal dispensing, and the width and depth information of the dispensing position cannot be given, which will lead to glue dispensing. Some places are full and some places are not enough

Abstract

The invention discloses 3D following closed-loop dispensing equipment of irregular hook face lens. The 3D following closed-loop dispensing equipment of the irregular hook face lens comprises an electric cabinet, a workbench is arranged at the top end of the electric cabinet, a through hole is formed in the middle of the workbench, initial positioning jigs are arranged at a port of the through hole, an angle adjusting jig is arranged at the bottoms of the initial positioning jigs, a vacuum chuck is arranged between the two initial positioning jigs, the rear end of the vacuum chuck is connectedwith a W-axis servo motor, a needle aligning camera is arranged on the left side of the vacuum chuck, supports are arranged on the two sides of the working area, a Y-axis module is arranged on the support on the right side, a Y-axis servo motor is arranged at the rear end of the Y-axis module, and a linear sliding rail is arranged on the support on the right side. According to the 3D following closed-loop dispensing equipment, the technical problems of inaccurate dispensing track, high reject ratio, no closed-loop control, high dependence on the jigs and the like of a traditional curved lens can be effectively solved, gluing does not depend on consistency of the lens and the jigs as well, dispensing can be rapidly and accurately carried out in a closed-loop mode, and the production efficiency of a production line can be greatly improved.

Description

technical field [0001] The invention relates to the fields of intelligent manufacturing, equipment automation and fluid control, in particular to a 3D following closed-loop dispensing equipment for irregularly curved lenses. Background technique [0002] At present, conventional lens dispensing is done by teaching or 2D visual positioning. Teaching: This requires a good consistency of the product and a very precise fixture; because the lens is an irregular surface, it is difficult to make a very precise fixture, resulting in a high defect rate and requiring a lot of post-processing rework. 2D visual positioning: Since the lens is an irregular surface, 2D positioning can only determine the XY plane. Once there is an error in the Z direction, there will be a large deviation in the dispensing track, resulting in a high defect rate. [0003] Traditional curved lens dispensing cannot give precise positions. Once there is a slight difference in the lens or the fixture is not acc...
