Description

Technical Field

[0001] The utility model relates to the field of glass production and processing, in particular to a device for synchronously removing dust from both sides of a flat glass. Background Art

[0002] In the glass product inspection process, especially the optical inspection process, water stains that are difficult to detect with the naked eye, floating dust, and fine impurities such as fluff are clearly visible under the existing ultra-high resolution camera lens. However, the existing optical inspection algorithm cannot distinguish which are defects of the glass product itself and which are water stains, floating dust, and fluff, which can be removed. Extremely fine water stains, floating dust, and fluff can lead to misjudgments and seriously affect the accuracy of optical inspection. It takes a lot of manpower and material resources to make secondary copies of misjudged glass products, which seriously reduces the inspection efficiency. Before the glass is inspected, its surface needs to be dusted. The glass surface dust removal equipment can refer to the Chinese utility model patent with application number CN202320568327.3 and the name of a surface cleaning device for photovoltaic glass production. Although this dust removal equipment has certain cleaning operations, it cannot completely remove impurities such as floating dust and fluff on the glass surface. At present, some large glass manufacturers in the industry have built Class 10,000 dust-free workshops for optical inspection equipment and built special clean rooms to eliminate the interference of fine impurities on optical inspection algorithms. This method also has the following disadvantages: First, the construction cost of Class 10,000 dust-free workshops and special clean rooms is huge, and their daily energy consumption is also very high, which is not affordable for ordinary small and medium-sized manufacturers, and is not conducive to energy saving, cost reduction and efficiency improvement; Second, the construction of Class 10,000 dust-free workshops and special clean rooms requires a large renovation space, or even an independent factory building. It is difficult to carry out corresponding upgrades and renovations on existing production lines (factories) without sufficient renovation space reserved; Third, Class 10,000 dust-free workshops and special clean rooms have a certain threshold for the skills and literacy of operators, which increases the cost of employment.
