Description

Technical Field

[0001] The utility model relates to the technical field of glass coating, in particular to a roller coating device capable of preventing chuck marks. Background Art

[0002] From the perspective of aesthetics, the existing photovoltaic modules have lower and lower requirements for frames, and even cancel the frames, retaining the expansion joints for installation, which can be described as seamless connection. Here, the requirements for the glass surface are more stringent. When AR anti-reflection coating is applied to glass, the clamping mark and the trailing mark need to be strictly controlled.

[0003] like Figure 1 As shown, the main roller is fixed on the machine body, with a high and low leveling device, but it is fixed after adjustment. Since the main roller is in a fixed position, its function is to support the transmission belt and prevent the belt from being greatly deformed. At the same time, it can provide sufficient support when the glass substrate passes through. It is precisely because of this support that the chuck print during glass coating is affected. The reason is that the gap between the coated PU rubber roller and the belt is smaller than the thickness of the glass, generally 0.2-3mm smaller. The rotation direction of the coated PU rubber roller is opposite to the transmission direction of the glass, that is, during the roller coating process, the coated PU rubber roller gives a pushing force to the direction of glass movement. With the support force of the main roller and the friction between the glass and the belt, the glass is squeezed into the rubber roller. At this time, there is a pause in the extrusion deformation process of the glass and the coated PU rubber roller, so the coating on the head will be a little thick, resulting in a color difference band visible to the naked eye, generally 5-7mm, and severe cases can reach 10mm, which is unacceptable. It is inevitable that there is a thickness difference in the glass during the production process. In the nano-level coating, the thickness of 0.1mm is a thousand-level difference relative to the 100-level coating. The deviation of thickness makes a great difference to the deviation and uniformity of the glass surface. Therefore, the utility model adjusts the chuck print through the roller coating equipment and optimizes the influence of the thickness difference on the coating. Utility Model Content
