Problems solved by technology

[0003] The invention patent with the patent number of 201310086231.4 is the first to propose the automatic detection of lens defects by using the machine vision method, and builds the prototype of the online detection line, but the content involved in the patent is not very specific to the detection of the lens; the patent with the patent number of 201310289482.2 The invention patent proposes a three-disc lens sorting system, which uses a disc structure to switch between loading, unloading and inspection stations, which effectively improves resource utilization, but its overall structure has a great impact on visual detection of light sources and camera layout. Restrictive, and the patented loading and unloading system is not very adaptable to the size of the lens

Embodiment 1

[0022] The lens defect detection process takes the four-station online detection of a single lens defect as an example. The implementation steps are as follows:

[0023] 1. The front-end feeding production line is ready, PLC17 sends a pulse signal for the feeding process through the motor driver 19, and the feeding control motor 1 moves in the X and Y directions to the unloading position of the front-end feeding production line;

[0024] 2. PLC17 controls the electro-pneumatic valve 22 to generate negative pressure through the I / O port, so that the vacuum suction cup 3 for feeding the material will suck up the lens;

[0025] 3. The loading cross slide 2 moves through the lens to the position of the lens clamping jaw of the loading station, and the PLC17 controls the parallel cylinder 8 to perform the clamping task, and at the same time releases the negative pressure in the vacuum suction cup 3 for the material feeding, so that the lens is clamped by the lens Claw...

Abstract

An online detecting device for the defect of a lens is composed of a feeding device, a discharging device, an image collecting device, a dust removal device, a parallel finger, a rotary workbench and a control system. The control system is connected with the feeding device, the discharging device, the image collecting device, the dust removal device, the parallel finger and the rotary workbench. Detecting and recognizing devices are arranged on the rotary workbench at equal intervals. The online detecting device is characterized in that the feeding device is arranged on a clockwise station of the detecting and recognizing devices; the discharging device is arranged on an anticlockwise station of the detecting and recognizing devices; the dust removal device is arranged at the front end of a detecting station, and the center of the dust removal device is located on the circumference of the rotary workbench; the parallel finger is fixed to the rotary workbench. The defect of an automatic detecting technology of the defect of the lens is overcome, and the automation level and efficiency of detection of the defect of the lens are improved.

Description

technical field [0001] The invention relates to an online detection device for lens defects, in particular to an on-line detection system for lens defects using machine vision technology, which belongs to the technical field of mechatronics. Background technique [0002] At present, the automation level of the lens production process is gradually improving, but the lens quality inspection is still all done by manual inspection. On the one hand, lens quality inspection is an important link to ensure the pass rate of ex-factory lenses. Manual inspection largely depends on the experience and technology of inspectors, and is easily affected by subjective factors, individual differences and other factors, resulting in a high false detection rate; On the one hand, real-time monitoring of lens quality is beneficial to guide production equipment and improve the pass rate of lenses in the production process, while manual inspection is not conducive to the connection between productio...
