Please refer to fig. 1 to fig. 3; a manufacturing method of large-scale vehicle body color strip paint spraying comprises the following steps:
a planning step, namely collecting lines formed by splicing gaps of vehicle windows, vehicle lamps, vehicle doors and skins on a vehicle body 100, and taking the actually existing lines as a first reference line 1; and a second reference line 2 is formed by extending horizontally and vertically on the basis of the first reference line 1.
A designer establishes two-dimensional coordinate axes of each side face of the vehicle body through two-dimensional drawing software or drawing paper, and a first reference line 1 and a second reference line 2 in the two-dimensional coordinate axes are staggered to form a positioning frame.
A preparation step, in which a designer places a color bar pattern of a vehicle body to be formed on the two-dimensional coordinate axis, divides the color bar pattern of the vehicle body into a plurality of pattern blocks attached to different paint-spraying template papers 3 according to the color bar pattern of the vehicle body and a positioning frame, edits the proper positions of the paint-spraying template papers in the positioning frame, and records the position relation between the edge of each paint-spraying template paper 3 and the positioning frame; thereby forming a paint spray template positioning diagram.
For example, the first reference line 1 is horizontally spaced from the first reference line 1 or vertically spaced from the second reference line 2. So that the exact position of the painted stencil paper 3 on the vehicle body 100 can be easily obtained.
The proper position of each spray painting template paper in the positioning frame can be edited by considering the integrity of the pattern block, the margin required by each spray painting template paper and the like.
In this embodiment, each of the painting template papers 3 has a rectangular structure, and can be conveniently positioned with respect to the first reference line 1 and the second reference line 2 of the positioning frame. In other embodiments, the stencil paper 3 may have other geometric shapes.
And a film pasting step, namely pasting each paint spraying template paper 3 to the corresponding recording position of the vehicle body skin by taking the positioning frame formed by the first reference line 1 and the second reference line 2 as a reference according to the paint spraying template positioning diagram.
A spraying step, tearing off the color strip pattern shape of the spray painting template paper 3 through an easy-to-tear line; the spray painting template paper is sprayed with paint, so that the color bar patterns can be formed in the easily torn line customized patterns in the spray painting template paper 3.
The process method divides the color bar of the car body into a plurality of pattern blocks; and attaching the fragmented spray painting template paper 3 to the vehicle body using a positioning frame formed by the first reference line 1 and the second reference line 2. Can be accurate spray paint and form the colored stripe pattern of automobile body, again can greatly reduced the unrestrained rate of the template paper material that sprays paint, reduce the quantity of the template paper 3 that sprays paint. And after the process improvement method is adopted according to practice, the amount of the paper for painting can be saved by 30-50% by one trolley. The whole template can be hung on the automobile body by a plurality of people in the original workshop, and the whole template can be operated by one person, so that the whole manufacturing efficiency is better and the difficulty is lower.
In addition, the workshop does not have accurate location when the operation originally, and different people of different batches have the error when trailer body, in this application, all adopt same template positioning diagram that sprays paint to first datum line, second datum line on the automobile body are the benchmark, carry out the pad pasting, can keep the car uniformity in batches of preparation more.
In the embodiment, in the preparation step, the vehicle body skin is subjected to base paint spraying; such as pure white base paint spraying of the vehicle body skin.
The margin between the edge of the stencil paper 3 and the internal pattern is preferably 10CM to 30CM. However, in order to prevent the area of the stencil paper 3 from being contaminated during painting, in the present embodiment, the spaced blank portions of each stencil paper 3 are masked with a thin film in the film-attaching step.
In the step of laminating, since only part of the second reference line 2 is needed, when the second reference line 2 is needed, the second reference line 2 needed is laminated on the body skin by using the positioning adhesive tape. Specifically, the positioning tape extends in the horizontal direction or the vertical direction along the first reference line 1 on the vehicle body 100, and is not prone to error.
Wherein, the width of the positioning adhesive tape is preferably 0.5 CM-2.5 CM. The positioning adhesive tape is preferably a yellow adhesive tape or a masking tape.
In this embodiment, adopt the yellow adhesive tape that the width is 1.2CM, its colour is showing, pastes convenient and fast.
To save the spray painting stencil paper 3 even further; in an embodiment, the following processing steps are preferably used for the lines or the ribbon pattern:
and a preparation step, namely, arranging the lines or the ribbon patterns to be formed on the two-dimensional coordinate axis, and recording the position relation between the edges of the lines or the ribbon patterns and the positioning frame.
And a film pasting step, namely pasting edges on two sides of a line or a ribbon pattern by using a positioning adhesive tape by taking a positioning frame formed by the first reference line 1 and the second reference line 2 as a reference, and shielding the outer side of the positioning adhesive tape by using a thin film.
And a spraying step, namely spraying paint on the area of the lines or the ribbon patterns.
Thus, for a line or ribbon pattern, painting of the pattern can be accomplished without the use of the stencil paper 3.
Referring to fig. 4, in the case that the color stripe pattern of the car body has a plurality of complete patterns spaced apart from each other, the preferred method is to assign the complete patterns spaced apart from each other to different stencil papers 3. And each of the painting stencil papers 3 is rectangular. Therefore, the positioning frame formed by the first reference line 1 and the second reference line 2 can be used for positioning, so that the color bar pattern can be attached to an ideal vehicle body position.
Wherein, if a complete pattern width in the colored stripe pattern of automobile body is great, and the pattern on left and right sides is different sides in the height, then can cut apart into a plurality ofly with this complete pattern, splice again, can practice thrift certain template paper 3 that sprays paint.
Therefore, the painting template paper 3 of the manufacturing method for painting the color strips of the large-scale vehicle body can be spliced closely or spliced at intervals according to actual needs.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
