Embodiment Construction
[0036] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] Such as figure 1 As shown, the present invention proposes a two-dimensional code engraving process for metal products, which includes the following steps:
[0038] Step S10, loading the product to be engraved into the positioning jig to position the product to be engraved.
[0039] The specific process is: place the product to be engraved in the positioning jig before the laser is applied to the product to be engraved, and then position the product to be engraved.
[0040] The product to be engraved is loaded into the positioning jig and the product to be engraved is positioned,...

The invention discloses a QR code engraving process for a metal product. The QR code engraving process comprises the following steps: a to-be-engraved product is loaded into a positioning jig and positioned; a laser machine is started, the bottom of the to-be-engraved product is scanned in a laser manner, and a QR code engraving area is formed; and the laser machine is started and a QR code is engraved in a laser manner in the QR code engraving area. According to the QR code engraving process provided by the invention, the surface of the to-be-engraved product is oxidized and becomes rough through a laser beam, so that the non-reflective QR code engraving area can be formed; then, a QR code pattern is engraved in a laser manner in the QR code engraving area, so that a QR code recognition lens can be prevented from being influenced by the reflective effect of a metal surface when recognizing the QR code, and then the QR code on the metal surface can be accurately recognized; and by theadoption of jig positioning and programmable automatic control, the QR code engraving process is applicable to large-batch production and processing, so that the production efficiency can be improvedand the production cost can be reduced.
Description
technical field [0001] The invention relates to the field of two-dimensional code processing, in particular to a two-dimensional code engraving process for metal products. Background technique [0002] As a kind of information identification label, two-dimensional code is widely used in various fields. When the two-dimensional code is used on the metal surface, it is generally realized by pasting the two-dimensional code label. The font color of the two-dimensional code on the two-dimensional code label forms a color difference contrast with the white paper, and the pasted label is easy to be read by the scanning gun lens. Pick. However, the pasted labels are easy to come off and do not take advantage of long-term use. [0003] The existing technology of the existing products to be engraved all uses two-dimensional codes to directly laser onto the metal products, only for laser marking, but due to the high surface finish of the metal products, reflections are generated dur...
