Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a manufacturing method for a vehicle N.

The automatic rear window is manufactured by integrally forming a synthetic resin frame around the outer periphery of the window glass. The 11th bacterium is an oblique view showing a part of the middle rod in the mouth, and Figs. In, 1 is Pode,
2 is an opera window, 6 is glass, 4 is a synthetic resin window, and 5 is a mask jig.

The manufacturing method shown in Figure 2 includes 6 mounting ports; 4 installed frames;
Cover the unpainted area with the mask jig 5, spray paint from the paint gun 7 to paint the painted area indicated by arrow a, and attach the frame 4 to the glass (not shown) with the mounting bolts 6 to close the window. Manufactured.

The manufacturing method shown in FIG. 5 includes integrally forming a frame 4 on the outer periphery of the glass 6 with synthetic resin, covering the non-painted part with a mask jig 5,
Paint is sprayed from the paint gun 7 to paint the painted area a,
manufactures windows.

The window manufactured in this way has a cushioning material 8 and a frame 4.
It is attached to the vehicle body/ξ panel 10 via the sealing material 9.

However, in such conventional window manufacturing methods, in order to prevent paint from adhering to non-painted parts,
Painting was done by covering the area with a mask jig made of metal or resin, which caused the following problems.

(1) The parting line between the painted part and the non-painted part becomes unclear, resulting in poor tread visibility.

(2) Damage to the coating film itself due to attachment and detachment of the jig.

■ High cost due to the use of highly accurate jigs.

■ Requires equipment and man-hours to clean the jig, leading to higher costs.

This invention has been developed to address these conventional problems, and involves forming a removable coating layer on the surface of the window crow in advance, forming a frame and performing surface treatment, and then removing unnecessary coating. By removing the layers,
The purpose is to solve the above problems.

This invention provides a method for manufacturing a window in which a frame is integrally formed with a synthetic resin around the outer periphery of the window glass, and includes the following steps: a) forming a peelable coating layer in advance on at least a portion of the glass including the outer periphery; b) coating. C) forming a surface treatment layer on the frame; and d) applying a coating layer along the inner circumference of the frame. A method for manufacturing a window, which includes the steps of cutting and peeling.

This invention will now be explained based on the drawings. 4 to 11 are vertical cross-sectional views showing a method of manufacturing a window according to an embodiment of the present invention, FIG. 12 is a cross-sectional view of FIG. 11, and FIG. 13 is a horizontal cross-sectional view showing an installed state. Yes, first
The same reference numerals as those in the figures to FIG. 3 indicate the same or corresponding parts.

The window manufacturing method includes applying a removable coating layer 11 in advance to a portion including at least the outer peripheral edge of the side surface of the glass 6.
Form it. The coating layer 11 is formed by applying a liquid material that solidifies into a film, such as a synthetic resin coating agent such as olefin resin or polyvinyl chloride, by spray coating or the like to form a film, which is then solidified into a film. Form. Of course, resins made of the above materials, polycarbonate resins, polyester resins, ABS resin, etc.
It may also be formed by pasting a film of oil or the like.

'The matrix coating layer 11 may be formed on the entire surface of the glass or only on the outer periphery.

The crow 6 with the coating layer 11 formed thereon is set in an injection mold to form a frame 4 around the outer periphery of the crow 6, as shown in FIGS. 4 to 7V. This process is based on so-called outsert injection molding, in which a crow 6 is inserted between a lower mold 16 and an upper mold 14 in which a cavity space 12 is formed in a portion corresponding to the outer periphery of the crow B.
The frame 4 is integrally formed by injecting synthetic resin such as ABS resin. FIG. 4 shows the state in which the glass 6 is set on the lower mold 16, FIG. , the resin is injected through the runner 16 and the gate 17, and Figure 7 shows the extrusion pin 18 extruding the glass 3 with the frame 4 formed thereon.

After the frame 4 has been formed, the crow 3 is then subjected to a surface treatment process. Surface treatments include plating such as chrome plating, vacuum deposition, metal deposition such as sputtering, and painting, and these can be applied alone or in combination. FIG. 8 shows a state in which metal vapor deposition has been performed, and a vapor deposition layer 19 is formed over the entire surface of the coating j-11 of the glass 6H, including the frame 4. Subsequently, as shown in FIG. 9, a mask jig 5 is placed over the non-painted area, and paint is sprayed from a paint gun (not shown) to form a paint film layer 20.

After the surface treatment process has been completed as described above, the glass 6 is cut into the coating layer 11 along the inner peripheral edge of the frame 4 with a cutter 21, as shown in FIG. 10, and as shown in FIGS. Unnecessary portions of the coating layer 11 are peeled off and removed. FIG. 11 shows a cross section taken along the line A-A in FIG. 12, and arrows indicate peeling in five directions.

1''J): The window is completed, and as shown in FIG. 9
The cushioning material 8, sealing material 9, and vehicle body panel 10 shown in the figures to FIG. 11 show virtual positions.

In Example 1, the material and forming method of the coating layer 11 are not limited, and the method for peeling off the surface-treated layer 11 is described in which a cut is made with the cutter 21 after the surface treatment. You may also make a cut in the front. This invention is applicable not only to window windows but also to other vehicle windows.

As mentioned above, according to the present invention, only unnecessary portions of the removable coach ink layer formed on the glass surface before surface treatment are removed after surface treatment, and the following effects can be achieved. is obtained.

■ The parting line between painted and non-painted parts becomes clearer.

■ No need for masking jig, resulting in lower cost.

■ No damage to appearance due to jig wear.

■ Equipment and man-hours required for cleaning jigs can be omitted.

■ Once a coating layer is formed, it can be made bright by surface treatment such as plating or gold maple vapor deposition, and the portion attached to the glass surface can be removed together with the coating layer.
