At present, glass surface spraying has been applied to glass reinforcement in actual production, but in the workshop for glass bottle storage, transportation, customer filling line and other processes, glass bottle surface spraying is often prone to damage and damage, thus significantly reducing the glass The ability of the surface to resist the use of contact, the quality of the glass bottle cannot be guaranteed, and the glass bottle is easily damaged when it reaches the customer.

Defects and deficiencies of existing technical means for glass bottle surface spray inspection:

1. Anti-scratch test: Hold the neck of the bottle with your hand and rub the bodies of the two bottles against each other in the circumferential direction. If there is no scratch, it is qualified. However, this method is difficult to control because the friction of the bottles is difficult to control, so the test results are accurate. The degree is poor.

3. Reciprocating scratch instrument: When using the reciprocating scratch instrument for inspection and testing, the pressure during contact is not controlled, and the test results have no reference.

At present, the Chinese patent whose publication number is CN108439820A discloses a glass bottle surface spraying process. The process is as follows. First, the glass bottle is dedusted, and then the glass bottle is sent to the first electrostatic hanging cup spraying device to spray a layer of UV paint. As the bottom glaze; the glass bottle sprayed with the bottom glaze is sent to the first infrared leveling machine for leveling treatment; the glass bottle after the bottom glaze leveling treatment is sent to the first UV dryer for drying treatment; the bottom The glass bottle after glaze drying is sent to the vacuum coating machine for coating treatment; the coated glass bottle is sent to the second electrostatic hanging cup spraying device to spray a layer of UV paint as the top glaze; the glass bottle sprayed with top glaze Send it to the second infrared leveling machine for leveling treatment; send the glass bottle after the surface glaze leveling treatment to the second UV dryer for drying treatment; send the glass bottle after the surface glaze drying treatment to laser laser engraving Engraved patterns on the machine.
