Problems solved by technology
[0003] When performing thin film evaporation processing, it is necessary to ensure that the processing box is in a vacuum state, and when the processing personnel replace the workpiece, the outside air will fill the entire processing box and also cause the internal evaporation molecules to be lost, making the vacuum pump during subsequent processing The workload is large, and it needs to be reheated and evaporated to replenish new evaporated gas; the number of workpieces processed at a time is small, and the replacement process is more time-consuming and laborious
Moreover, the existing glass coatings are uniformly coated, and the types of glass processed are single, which cannot meet the individual needs of different customers.

Embodiment Construction
[0030] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0031] Such as Figure 1-Figure 6 Shown, a kind of glass surface thin film vapor deposition improvement process of the present invention, this process comprises the following steps:
[0032] S1, fixing the glass to be evaporated in the thin film evaporation equipment;
[0033] S2, using a flame to bake the glass in S1 to preheat the glass;
[0034] S3, then, immediately evacuate the film evaporation equipment, and then heat and evaporate the glass to make the film adhere to the glass surface; set a plurality of heating plates arranged in an array on the back of the glass, and while performing evaporation, the heating plate Heating the glass; this process can control the temperature of the glass by setting the heating blocks arranged in an array ...

The present invention relates to the technical field of glass coating, in particular to an improved process for film evaporation on glass surface, which comprises the following steps: S1, fixing the glass to be evaporated in a film evaporation device; S2, using flame to The glass in S1 is baked to preheat the glass; S3, then, the film evaporation equipment is evacuated immediately, and then the film is heated and evaporated to make the film adhere to the surface of the film; multiple arrays are set on the back of the glass The arranged heating plate heats the glass while vapor deposition is being carried out; after S4 and S3 are completed, the glass is taken out for the next step. This process can control the temperature of the glass by setting the heating blocks arranged in an array on the back of the glass, and the gas flow on the glass surface changes due to different heating, so the non-uniformity requirements of the glass coating can be realized.
Description
technical field [0001] The invention relates to the technical field of glass coating, in particular to an improved process of film evaporation on the glass surface. Background technique [0002] Evaporation coating is often called vacuum coating, which is characterized in that under vacuum conditions, the material evaporates and condenses to form a film on the glass surface, and then after high temperature heat treatment, a film with strong adhesion is formed on the glass surface. [0003] When performing thin film evaporation processing, it is necessary to ensure that the processing box is in a vacuum state, and when the processing personnel replace the workpiece, the outside air will fill the entire processing box and also cause the internal evaporation molecules to be lost, making the vacuum pump during subsequent processing The workload is large, and it needs to be reheated and evaporated to replenish new evaporated gas; the number of workpieces processed in a single pro...
