Problems solved by technology

[0003] The above-mentioned glue spraying processing method for automotive interiors is prone to uneven glue spraying, so the product defect rate is relatively high, and the processing cycle is also long
In addition, if the grooves of the trim panels are too deep, there will be spray glue that cannot be sprayed in.
[0004] In addition, the composite hot-melt adhesive on the back of the skin of automotive interior parts must be heated to activate the colloid. At the same time, the hot-melt adhesive cools quickly. For some complex shapes, the processing cycle is long, and it is easy to fail, which is not conducive to improving production efficiency.

Embodiment 1

[0029] (1) Compound low-VOC (volatile organic compound) acrylic non-woven substrate double-sided adhesive on the back of the skin;

[0030] (2) Put the back side of the skin compounded with double-sided adhesive into the puncture machine to puncture. Due to the high density of the double-sided adhesive layer, a layer of film is formed, and it is easy to wrap air into it when it is wrapped and cannot be discharged, causing a bulging phenomenon. Use a puncture machine to puncture dense and small holes in the double-sided adhesive layer, which is convenient for coating processing and can prevent air trapping and swelling during coating;

[0031] (3) Put the PP material interior pattern plate into the EDM fixture, and perform spark treatment on the complex shape of the PP material interior pattern plate through the EDM process (such as figure 2 Shown), so that the adhesion is stronger when the EDM area on the template is attached to the skin;

[0032] (4) Put the above-mentioned...

Embodiment 2

[0037] (1) Compound the low-VOC non-substrate double-sided tape on the back of the skin;

[0038] (2) Put the above-mentioned skin compounded with double-sided adhesive back into the puncture machine for puncture, and use the puncture machine to puncture the double-sided adhesive layer into dense and small holes;

[0039] (3) Put the above-mentioned punctured skin face down into the skin bonding fixture, put the bonding surface of the ABS material interior panel into the movable mold, and then press down the movable mold so that the skin and the The large surface of the ABS interior panel is pasted;

[0040] (4) Start the pneumatic insert, and the pneumatic insert punches up to push the skin into the gap reserved by the pattern plate;

[0041] (5) Start the automatic flanging mechanism to flang the skin, and the worker takes out the product to obtain the car door trim product with the skin attached.

Embodiment 3

[0043] (1) Compound the double-sided adhesive on the back of the skin;

[0044] (2) This processing is a relatively moderate shape, so the puncture needles in the areas that are not easy to bulge can be removed, or part of the puncture needles can be removed to increase the needle spacing. The specific spacing can be adjusted according to needs. Put the above-mentioned skin compounded with double-sided adhesive back into the puncture machine for puncture, and use the puncture machine to puncture the double-sided adhesive layer to make small holes;

[0045] (3) Put the PP material interior pattern plate into the electric spark fixture, and discharge the complex shape of the interior pattern plate through the electric discharge process, so that the adhesion force is stronger when the electric spark area on the pattern plate is attached to the skin powerful;

[0046] (4) Put the above-mentioned punctured skin face down into the skin bonding fixture, put the PP material interior ...

Abstract

The invention discloses an automobile door interior trimming panel skin attaching method. The automobile door interior trimming panel skin attaching method is characterized by comprising the followingsteps of (1) compounding a double faced adhesive tape on a skin; (2) perforating intensive and fine holes in the double faced adhesive tape layer on the skin; (3) treating a shaping plate by using anelectric spark process; (4) laminating the surface and the big face of the shaping plate; and (5) flanging. According to the automobile door interior trimming panel skin attaching method, the machining efficiency is high; the automobile door interior trimming panel skin attaching method can be suitable for automobile interior trimming parts with various shapes; by compounding the double faced adhesive tape, the harmful substances are obviously reduced; compared with a traditional adhesive spraying mode, the automobile door interior trimming panel skin attaching method is more environmentallyfriendly; the reject ratio of the products machined by the method is very low; and the production cost can be effectively saved.

Description

technical field [0001] The invention relates to the technical field of production of automobile interior trim parts, in particular to a method for attaching the skin of an automobile door trim panel. Background technique [0002] In order to improve the product grade, many automotive interior parts often cover various skins on the template according to the needs of the product used. Traditional automotive interior parts are basically used as a spray gun to spray solvent-based glue or water-based glue on the back of the skin and the front of the template, and then attach the skin to the template; or spray on the back of the skin and the front of the template Hot melt adhesive, when it needs to be used, heat it to activate the glue, and then stick it to the template. [0003] The above-mentioned glue spraying processing method for automotive interiors is prone to uneven glue spraying, so the product defect rate is relatively high, and the processing cycle is also long. In ad...
