Problems solved by technology

However, the current scribing is carried out directly on the metal, which partially damages the strength of the metal and reduces the service life of the material. In automatic scribing, an optical machine appears, which can use the change of light intensity and wavelength to Patterns are formed on some materials, but in electromagnetic waves, only the energy of ultraviolet light is relatively high. Although the energy of electron beams is higher than that of ultraviolet light, its high energy will damage the performance of materials. Therefore, it is more feasible to use ultraviolet light to scribe, but It is difficult to form a pattern on the substrate with the automatic ultraviolet scribing system alone. Therefore, it is necessary to cooperate with this automatic ultraviolet scribing instrument to form a color pattern on the profile under the action of ultraviolet light to distinguish it from other parts.

Abstract

The invention discloses an automatic marking and color developing function coating which comprises the following components in percentage by weight: 40-70 percent of marking function resin, 10-40 percent of cyclohexanone, 10-20 percent of photosensitizer additive, 5-10 percent of 8'-substituted indole spirooxazine and 5 percent of 1173 photo initiator. The coating is mainly used for the marking and the color developing of ship steel plates and coiled materials. The marking automation and the production efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a functional coating for automatic scribing and color development. Background technique [0002] In the shipbuilding industry, the basic process is the processing of profiles, that is, the scoring and cutting of profiles. For a long time, it is an operation that relies on the inherent skills of workers, with high labor intensity, low production efficiency, poor marking and cutting accuracy, and uncontrollable. With the development of industrial robots and industrial automation technology, the profile robot automatic scribing and cutting system aimed at expanding production automation and improving operation accuracy brings hope to reduce labor intensity and improve production efficiency. [0003] There is also the problem of scribing in the coil industry. Traditional manual scribing consumes a lot of physical strength and manpower, and its speed is difficult to meet the actual needs. It ...
