Description

Technical Field

[0001] The utility model relates to the technical field of glass detection, in particular to an online device for detecting glass breakage. Background Art

[0002] The competition in the photovoltaic market is becoming increasingly fierce. Production capacity is increasing, and costs need to be continuously reduced. In terms of personnel safety, the requirements for the intelligence of equipment are also getting higher and higher. The possibility of glass breaking during the production process is inevitable. The broken glass will cause the production line to be temporarily shut down, affecting production capacity. There are safety risks when personnel handle it, causing work injuries. Therefore, it is necessary to improve the intelligence of the production line and the safety of automation.

[0003] At present, many equipment manufacturers use cameras to develop online detection equipment. Through the system CPU + algorithm combined with the graphic comparison analysis of the defect database, the defects on the glass surface are compared to judge the quality of the glass. This detection method is a good way for high-speed processing. The equipment produced by using camera shooting to judge glass defects will be more expensive, but it can detect defects such as stones, bubbles, open bubbles, scratches, broken corners, etc. in the glass.

[0004] However, if the glass on the production line is broken, especially the broken pieces in front of the coating machine, screen printing machine, and tempering furnace, entering the equipment may cause damage to the equipment, and there are risks of replacement and maintenance such as scratches on the coating rubber roller, broken screen printing screen, and blockage of the tempering furnace. Moreover, the problems of broken glass and broken corners are relatively simple, and the investment cost of using camera photography technology will be relatively high. Especially for the photovoltaic glass deep processing production line, multiple sets need to be configured, the investment cost is higher, and the occupied space is larger. Therefore, in terms of cost saving, high efficiency, safety, and labor saving, we use the fiber optic sensor series sensing mode instead of camera scanning. The use of fiber optic sensors selects the diffuse reflective beam diameter of the fiber optic sensor at a detection distance of about 2mm at a height of 30mm. Through the induction measurement of several or more than a dozen fiber optic sensors, it is determined whether the glass is broken. The basis for the judgment is that when the glass is broken or missing, the size of the entire glass in the length and width directions changes, so we can determine whether the glass is broken or damaged. The system can sound an alarm and even link the front-end and back-end equipment to stop immediately. It can continue production after automatic processing or human intervention. This can avoid inevitable damage to equipment or accessories and minimize downtime and harm to employees.

[0005] The existing technology uses a camera to take pictures and compare them with defect pictures in the database, and then determines whether they are qualified after CPU calculation and analysis. In order to take clear pictures, the camera must be a high-speed camera. At the same time, there are strict requirements on the brightness, spectrum and angle of the light source during the shooting process. The system operation also needs to be responsible for corrections. When the problem is serious, the manufacturer's personnel are required to go to the site for investigation and treatment. Relatively speaking, the level of the operator is required to be high, and it is a bit too heavy to use for a single defect problem of a lobe. The maintenance is highly professional, and the overall cost performance is not high. Utility Model Content
