The technological process of the two-dimension code anti-theft metal cover comprises the following steps: the method comprises the steps of feeding, stamping, glue injection, drying, covering, inner tagging (a first two-dimensional code), inner tagging detection, inner tagging dust removal, punching, deep drawing, curling, aluminum foil stamping pre-sealing, embossing, outer tagging (a second two-dimensional code), outer tagging detection, outer tagging dust removal, output (including detection rejection), infrared sterilization, appearance detection and packaging.

Step1, firstly, carrying out production such as basic round cover, glue injection, drying and the like by using a gantry punch press, using special coding easy-to-tear cover equipment for use, and adopting a double-channel or above multi-channel structure for an easy-to-tear cover production line.

Stamping: the cover is formed by a GT2A48 full-automatic numerical control press and a special die after punching.

Injecting glue: and (3) after the round cover is basically obtained by stamping, performing round cover glue injection production by adopting a GT2C28 high-speed rotary glue injection machine (glue injection mainly comprises the step of filling sealant in a cover groove and mainly plays a role in combined sealing of a cover and a can cover).

Drying: and after glue injection, heating in a two-section electromagnetic mode to dry the sealant.

And (4) covering: and (3) placing the dried basic cover into a coding station for conveying, utilizing a magnet to adsorb and position, and firstly carrying out integral coding on the outside of the basic cover (the general size is controlled within 6 x 6 mm-15 x 15 mm).

A coding process: A50-100W high-power infrared picosecond laser is adopted, the wavelength is 1064 +/-0.5 nm, the internal and external strong correlation data including laser burning generates graphics or digital information within 0.2-0.6 seconds, such as QR, DM and the like, and the graphics or the digital information are respectively endowed on a tinplate (the set position of the outer surface of a basic cover) and an aluminum film (the aluminum film sealing) to generate internal code and external code identification information, and correlation detection is carried out, wherein the internal and external coding processes are similar.

The detection process is that a detection procedure is carried out after the code assigning step, the codes assigned by the code assigning process are recorded, and a high-definition industrial video system or a camera and the like can be adopted.

Then punching, drawing and curling are carried out. (the punching is to punch a D-shaped inner ring by using a special die on the basis of a basic round cover, and the deep drawing and the curling are mainly to use the special die for the D-shaped ring to perform edge folding and safety protection, so that the problems of scratching and the like in the using process are prevented, and the standard method in the industry is adopted).

Step2, performing aluminum foil punching for pre-sealing and sealing, wherein an aluminum film with a thickness of 0.09mm is generally used, the upper and lower surfaces of the aluminum film are respectively composed of a protective layer and a heat sealing layer, and the coating thickness of the protective layer is generally 1.5 +/-0.5 g/m²Mainly plays a role in preventing the aluminum film from being scratched and protecting the aluminum film from being oxidized; the thickness of the coating film of the heat-sealing layer is generally 9.5 +/-1.5 g/m²The heat sealing process is generally that the upper die is 220 +/-10 ℃, the lower die is 200 +/-10 ℃, the heat sealing pressure is 0.5-0.6MPa, the speed is 80-300 times/minute, finally, the aluminum film hot melt adhesive layer is adhered to the integral code, and adhesive marks are left on the integral code after the aluminum film is torn.

And Step5, comparing the internal and external codes, and comparing the internal and external codes through high-definition camera visual detection and computer software to determine whether the internal and external codes are consistent. If the inner code and the outer code are mistakenly and uniformly rejected, a contact bypass machine (a mechanical arm and the like) or a sinking rejection mechanism is arranged at the tail end of the production line, and when the inner code and the outer code are detected through an outer code detection point, if the inner code and the outer code detection results are inconsistent, the easily torn covers are rejected through a rejection station.

Step6, carrying out surface dust removal and infrared sterilization on the easily torn cover, and then uniformly packaging: ultraviolet irradiation intensity during infrared sterilization is 20-50 μm/cm²And the dust removal and filtration precision is more than 0.2 um.

And Step7, performing metal can manufacturing, filling, two-dimensional code activation (a first two-dimensional code and a second two-dimensional code) and packaging.
