[0004] However, the prior art does not mention how to solve the offset after cleaning the material, and how to sort the material according to the size of the material when the material is coated by mixing, so that the present application proposes an automatic production line based on online film coating after cleaning to solve the technical problem. SUMMARY

[0005] One technical problem to be solved by the automatic production line based on online film coating after cleaning is that the size of the cover plate glass is measured by the visual measurement system, and the position correction mechanism displaces the cover plate glass to the specified position of the docking unloading conveying channel on the film coating conveying channel according to the size of the cover plate glass, so that the cover plate glass is sorted before film coating, and the subsequent film coating is completed according to the size.

[0010] In some embodiments, the visual measurement system comprises a camera and a light source installed above the film covering conveying channel, the camera is used to take pictures of the cover glass on the film covering conveying channel, and the illumination direction of the light source is towards the film covering conveying channel.

[0011] In some embodiments, the film covering mechanism further comprises a plurality of film covering machines composed of a film storage assembly and a film pressing and cutting assembly, and each film covering machine is respectively connected with a corresponding conveying area.

[0012] In some embodiments, the number of blank conveying channels is several, and each blank conveying channel corresponds to a conveying area.

[0013] In some embodiments, it further comprises a blanking mechanism, which sets conveying position determination data to distinguish the conveying positions on the blank conveying channel and classifies the cover glasses at the corresponding positions into boxes;

The outer sides of the two mounting supports 231 are respectively provided with an upper film pressing roller adjusting cylinder 232. The piston rod of the upper film pressing roller adjusting cylinder 232 is connected with the outer end of the mounting member 233. The mounting member 233 is slidably mounted on the inner side of the corresponding mounting support 231, so that the upper film pressing roller 23a1 is driven to move along the sliding direction of the mounting member 233 by the upper film pressing roller adjusting cylinder 232, thereby adjusting the distance between the upper film pressing roller 23a1 and the lower film pressing roller 23a2.
