Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of peristaltic pumps, in particular to a cooling treatment circulating device for coated optical lenses. BACKGROUND

[0002] In the optical lens coating equipment, in order to ensure the stability of the coating process, the substrate needs to be accurately cooled. The system drives the cooling liquid through the peristaltic pump to form a circulation in the closed pipeline. Due to its characteristics of no sealing and fluid isolation, the peristaltic pump can effectively avoid the pollution of the cooling liquid, so as to ensure the purity of the cooling medium flowing through the substrate clamp in the coating cavity, and finally realize high-precision and high-stability temperature control.

[0003] The peristaltic pump drives the rollers or pressing blocks through the transmission assembly to continuously extrude the elastic hose, so that the negative pressure and positive pressure alternating areas are formed in the hose. By using the pressure difference, the hose will suck the fluid from the inlet and push the fluid to the outlet, realizing the non-contact fluid delivery. However, during the rotation of the roller, the roller and the surface of the hose will slide relative to each other during the extrusion process, which will directly cause friction and wear of the hose. Long-term repeated extrusion and friction will cause local material fatigue and wall thickness thinning of the hose, and finally lead to damage, thereby reducing the service life and requiring replacement of the hose. For a long hose, frequent replacement will increase the use cost. SUMMARY
