Description

Technical Field

[0002] Optical lenses are essential components of machine vision systems, directly affecting image quality and the implementation and effectiveness of algorithms. An optical lens consists of lenses and a frame for mounting them. After the lenses and frames are manufactured separately, they need to be assembled. The final step in the assembly process is adhesive curing. This involves applying adhesive to the lens components, such as the final assembled lens element or spacer ring, and connecting it to the lens barrel. The curing of the adhesive prevents internal lens displacement or dislodgement, ensuring high-quality optical performance.

The loading transfer mechanism 31 transports the inspection tray 24 containing the optical lens to be inspected out of the loading magazine hopper 8. The loading robot 1 transfers the optical lens to be inspected to the transfer receiving table 26. The barcode scanner 27 performs an initial barcode scan on the optical lens to be inspected on the transfer receiving table 26. The optical lens is transferred by controlling the movement of the suction pen assembly through the combination of the Y-axis movement module 13, X-axis movement module 12 and Z-axis movement module 14. First, the fixture loading suction pen 17 picks up the optical lens to be inspected from the transfer receiving table 26, and then the fixture unloads the lens. The suction pen 16 picks up the optical lens that has been tested on the test fixture 32. Then, the fixture loading suction pen 17 places the optical lens to be tested that has been picked up onto the test fixture 32. Finally, the fixture unloading suction pen 16 places the picked-up tested optical lens into the NG tray 19 or OK tray 18 according to the test results. During the initial barcode scanning test, if the scan result is NG, the fixture loading suction pen 17 will not pick up the optical lens to be tested from the transfer receiving table 26 and place it onto the test fixture 32. Instead, it will place it directly into the NG tray 19 and then perform the next round of airtightness testing on the optical lens.
