The purpose of the present invention is to solve the shortcomings of the above-mentioned background technology, and provide a coating alignment process after the skin is weakened.

The technical solution adopted in the present invention is: a coating alignment process after the skin is weakened, comprising the following steps:

Step 1: Position the epidermis on the weakened membrane, and form the required weakening line after the cold knife or hob weakening is completed on the surface B of the epidermis;

Step 2: Fix the above-mentioned weakened epidermis on the first jig in reverse, and use the forward projection method to project the position of the weakening line on the surface A of the epidermis on the first jig, and place it on the surface A of the epidermis along the Put white tape on the position of the projected light, that is, mark the position of the weakening line on the surface B of the epidermis on the A side of the epidermis, and provide the visible position of the weakening line of the epidermis on the A side for the next step of epidermis covering;

Step 3: Put the skeleton on the second jig, adjust the position of the epidermis in step 2, align the white tape on the epidermis along the position of the projection light, complete the positioning, then heat it with a heat gun, and manually attach the epidermis to the package over the skeleton.

In the above step 1, the epidermis is provided with positioning holes, and the weakened membrane is provided with positioning pins, and the epidermis and the weakened membrane are positioned by the cooperation of the positioning holes and the positioning pins.

The weakened membrane has a profiling sinking step of the skin, and the profiling sinking step is 0.5mm larger than the contour of the skin.

In the above step 2, positioning holes are provided on the skin, and positioning pins are provided on the first jig, and the skin and the first jig are positioned by the cooperation of the positioning holes and the positioning pins.

In the above step 2, ensure that the position of the projected projection light projected on the first jig is consistent with the position of the weakening line of the surface B of the epidermis.

In the above step 3, ensure that the position of the emitted projection light projected on the second jig is consistent with the position of the weakening line on the skeleton.

The invention effectively reduces the alignment process, improves work efficiency and saves the consumption of auxiliary materials.

The invention ensures that the position deviation between the skeleton and the epidermis after weakening is less than or equal to 2 mm, effectively ensures that the weakening line position of the epidermis coincides with the weakening line position of the skeleton when the epidermis is coated on the skeleton, and reduces errors in the coating process.

The invention solves the problem that the weakening line of the skin and the skeleton is misaligned because the position of the weakening line on the B surface cannot be visually observed when the weakened skin is coated, and improves the yield rate of the product and the efficiency of coating.
