Referring to fig. 4 and 5, embodiment 2 differs from embodiment 1 in that a filling groove 3 for filling the light shielding layer 2 is formed in the light transmissive template 1, and the light transmissive template 1 is positioned and attached to the product 5 before the laser welding process is started.
Referring to fig. 5 and 6, the surface of the transparent template 1 is machined or etched to form a filling groove 3 with a shape opposite to the shape to be welded on the product 5, and then the light shielding layer 2 is filled in the filling groove 3, so that the contour edge of the light shielding layer 2 can be attached to the contour edge of the filling groove 3.
Referring to fig. 4 and 5, the filling groove 3 is accurately machined in advance, so that the outline of a welding area on a product 5 is clear and accurate, and the welding precision is improved. Compared with a processing mode of processing a film in a region to be processed after a metal film is fully coated, the light-transmitting template 1 needs to transmit laser in the application, a laser welding region is carried out on a lower-layer product 5, no polishing processing is carried out, the light transmittance of the transparent template is good, and the processing precision is high. And the processing precision of the filling groove 3 on the light-transmitting template 1 is the contour precision of the shading area 11, and the processing precision is easier to control.
Referring to fig. 4 and 6, the thickness of the light-shielding layer 2 in the filling grooves 3 should be not greater than the depth of the filling grooves 3 so that the light-transmissive templates 1 can be stacked and placed in combination with each other when the light-transmissive templates 1 are stacked and stored.

And then a light shielding layer 2 is sprayed into the filling groove 3, and the light-transmitting template 1 is placed on a product 5 to be welded, so that the filling groove 3 faces the product 5. Laser shines to light-transmitting template 1 from light-transmitting template 1 top, and laser shines when being light-shielding layer 2 and is absorbed, reflects, and when laser shines on light-transmitting template 1 and does not cover light-shielding layer 2 region, laser shines on the work of products 5 through light-transmitting template 1, makes the welding go out on the work of products 5 with the light-transmitting template 1 on not cover the pattern of light-shielding layer 2 regional looks adaptation, and processing is quick, convenient, and the machining precision is higher. Transparent plastic materials are used as the light-transmitting template 1, and the filling groove 3 is not easy to damage during processing. The light shading glue, the daub and the like are directly filled into the filling groove 3 to be used as the light shading layer 2, so that the cost is low, and the processing and the manufacturing are convenient.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
