Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
In one embodiment, as shown in fig. 1, there is provided a two-color painting method for an automobile body, comprising the steps of:
color register is sprayed on the color register area 11;
overlaying a previously prepared master die-cut sheet conforming to the shape of the register area 11 over the register area 11;
the dominant color region 12 is painted with the dominant color.
According to the automobile body double-color spraying method provided by the scheme, the total die-cutting sheet with the shape consistent with that of the color register area 11 is prepared in advance, so that the color register area 11 is directly covered by the prepared total die-cutting sheet in the machining process without on-line on-site cutting, the on-site operation flow is simplified, the operation efficiency is improved, and the operation time is saved.
Particularly, in the case that the shape of the color register area 11 is complicated, it takes much time to cut the film for shielding the color register area 11 on site, which results in a long time for the whole operation and a long time for on-line cutting, and thus the production line has low processing efficiency. On the basis, the total die-cutting piece which is cut in advance is adopted, so that the operation time is saved, batch production is realized on the basis of the total die-cutting piece, the method is easy to realize even if the shape is complex, excessive time cannot be added to the preparation process, and the operation time can be saved on the whole. Therefore, the manufacturing cost can be effectively reduced.
In other words, when the design of the vehicle model is completed, the master die-cut piece is prepared in advance according to the shape of the color register area 11, and the master die-cut piece can be mass-produced in advance, so that the master die-cut piece prepared in advance is directly used on the automobile spraying production line. Specifically, the master die-cut sheet may be covered on the color register area 11 by means of pasting. For example, the overall die-cut sheet, which has an edge with an adhesive member 30 and is directly adhered to the vehicle body 10 along the edge, is shaped to conform to the color register region 11.
Specifically, in one embodiment, as shown in fig. 2, the process of preparing the total die-slice specifically includes the following steps:
acquiring a color separation line between a vehicle type color register area 11 and a main color area 12;

and developing and mass-producing the total die-cut sheet by using the digital-analog.
When the vehicle model design is determined and the color separation line between the color register area 11 and the main color area 12 is determined, a corresponding digital model is established according to the color separation line, and then the digital model is used for batch development and production of the total model slice. The master die-cut piece, which may be a disposable consumable, may be used directly on the painting line, one for each body 10.
Further, the total die-cut piece may be combined from a plurality of die-cut pieces. Specifically, as shown in fig. 3 and 4, the color register area 11 includes a roof area 111, an a pillar area 112, and a rear area 113, which are shaded areas in the drawing. At this time, the total die cut sheet may be divided into a roof area die cut sheet 20 (shown in fig. 5), a left a pillar die cut sheet 21 (shown in fig. 6), a right a pillar die cut sheet 22 (shown in fig. 7), and a rear tail die cut sheet 23 (shown in fig. 8). So that 4 die-cut sheets combine to form a set of said total die-cut sheets. In the use process, 4 die-cut sheets are respectively pasted on the corresponding areas.
Alternatively, instead of being made up of multiple separate die-cut pieces, the total die-cut piece may be a single integral piece of film conforming to the shape of the register area 11. In use, a single piece of film is adhered to the color register area 11 at one time.
Further, in an embodiment, the step of establishing the corresponding digital model according to the color separation line specifically includes the following steps:
and acquiring a space model of the color separation line, and converting the space model into the digital model applied to a plane, so that when the total die slice produced according to the digital model is covered on the color register area 11, the edge contour line of the total die slice is consistent with the color separation line.
In other words, a space pattern is formed based on color separation lines on the vehicle model and is not distributed in a plane, so that the space pattern needs to be converted into a digital model on the plane, and similarly, a shell enclosing a three-dimensional space pattern is unfolded on a plane, so that a total die slice capable of being matched and covered on the color register area 11 is processed according to the digital model.
More specifically, in an embodiment, the color register area 11 includes a roof area and a pillar area, and the step of establishing the digifax further includes the following steps:

The digifax is divided into a roof area digifax and a column area digifax according to the dividing line of the roof area and the column area, in other words, the digifax is divided into a form including the roof area digifax and the column area digifax.
Therefore, in one embodiment, developing and mass-producing the total die-cut slice using the digifax specifically includes:
the roof area die-cut sheets 20 are developed and mass-produced according to the roof area digifax, and the pillar area die-cut sheets are developed and mass-produced according to the pillar area digifax.
The roof area die-cut sheets 20 are then respectively affixed to the roof area and the pillar area die-cut sheets are affixed to the pillar area during the painting process.

the adhesive members 30 are provided at the edges of both the roof covering film and the pillar covering film.
In other words, the roof area die-cut sheet 20 is composed of the roof covering film and the adhesive 30, and the pillar area die-cut sheet is composed of the pillar covering film and the adhesive 30. The roof shielding film and the pillar shielding film are obtained by cutting.
Further, in another embodiment, developing and mass-producing the roof area mold cut sheet 20 according to the roof area digifax and developing and mass-producing the pillar area mold cut sheet according to the pillar area digifax specifically include the following steps:

The shape of the shaping groove is the shape of the total die slice.
Further, in one embodiment, the adhesive member 30 comprises a double-sided adhesive tape which is arranged along the entire circumference of the edge of the corresponding masking film.
In the spraying process, the master mould slice is adhered and covered on the color register area 11 by the double-sided adhesive along the color separation line, and the master mould slice is torn off after the main color area 12 is sprayed.
Further, in one embodiment, as shown in fig. 1, the two-color painting method for the automobile body further comprises the following steps:
