Problems solved by technology

Due to the small size and light weight of the small glass sheet, when the rotating speed of the turntable is high, the small glass substrate tends to move relative to the turntable, thereby slipping away from the groove, causing the gap between the small glass substrate and between the small glass substrate and the turntable. Collisions between the small glass substrates cause scratches and abrasions on the surface, affecting the dimensional accuracy and appearance quality of subsequent filters

Abstract

The invention relates to a holding device, which comprises a bearing device with an empty cavity and an air suction device, wherein the bearing device comprises a bearing part. The bearing device is provided with a plurality of through holes communicated with the empty cavity, so as to ensure that when the workpiece to be processed covers the through holes, the workpiece to be processed is matched with the bearing device to form a closed empty cavity. The air suction device which is communicated with the bearing device is used for sucking the air in the empty cavity. The invention further relates to a method for fixing the workpiece to be processed by the holding device. The holding device of the invention has simple structure, and the holding method of the invention has the advantages of convenient operation, excellent holding effect, effective productivity improvement and material conservation.

Description

technical field [0001] The invention relates to the technical field of lens production, in particular to a holding device and a holding method. Background technique [0002] At present, the surface of many industrial products is coated with functional films to improve various properties of the product surface. For example, an anti-reflection film is coated on the surface of the optical lens to reduce the reflectivity of the surface of the lens and reduce the energy loss of the incident light passing through the lens. Another example is to coat a layer of filter film on the surface of the glass substrate to filter out the light of a certain predetermined band, and make various filters.
