Abstract

PURPOSE:To easily and accurately set a bumper at the prescribed position by fitting a setting recognition part which is vertically provided to the position for masking the opening part formed to the bumper to the inner face of a boxy masking jig. CONSTITUTION:The bumpers 6, 10 of an automobile are placed on a supporting frame 2. Further a boxy masking jig 3 for masking the rears of the bumpers is provided to the part for placing the bumpers placed on the supporting frame 2. Furthermore a setting recognition member 4 which is vertically provided to the position for masking the opening parts formed to the bumpers is fitted to the inner face of the jig 3. As a result, in coating of the bumpers, the bumpers are easily and accurately set at the prescribed position. Therefore while masking failure based on positional failure and interference of a coating robot and the bumpers are prevented, high productivity is achieved.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an automobile bumper painting jig.

[Prior Art] Conventionally, black resin molded products have often been used for automobile bumpers, and in order to improve the overall design of the automobile, only specific parts are painted in the same color as the vehicle body. For example, see Japanese Patent Application Laid-Open No. 62-95178).

Such partial painting is performed by masking the parts to be left black and the opening parts where it is necessary to prevent paint from entering with masking tape or the like. However, especially for the back side where almost the entire surface is masked, in order to reduce the complicated work of applying masking tape etc. along the complex shape, a box-shaped masking jig with an upward opening is used to mask the back side. It may be possible to install the bumper with the front facing down.

However, although such a box-shaped masking jig can be expected to have the advantage of greatly reducing the amount of work required for masking, the gap between the box-shaped masking jig and the bumper must be at most 3 to 5 av. There is also a risk that paint may enter through the gaps and even reach the masked surface side through the openings, resulting in poor appearance.

Furthermore, when painting the front bumper and rear bumper side by side with a painting robot, it is possible to set the movement path of the painting robot as low as possible in order to improve the painting quality. If the gap between the bumper and the bumper is large, the bumper will be in a raised position above the predetermined position, causing the problem that the painting robot will hit the raised bumper when painting the other bumper.

[Problems to be solved by the invention] The present invention has been made in view of the problems in conventional bumper painting as described above, and has a masking jig that can easily mask the back side. To provide a bumper painting jig that allows easy confirmation from above that the bumper is in a predetermined position with respect to the masking jig and that there is no large gap between them.

[Means for Solving the Problems] The present invention provides a support frame on which a bumper of an automobile is placed, a box-shaped masking jig provided in a portion of the support frame on which the bumper is placed, and for masking the rear surface of the bumper, This invention relates to a bumper painting jig comprising a set confirmation member attached to the inner surface of the masking jig and erected at a position for masking an opening formed in a bumper.

[Function] Since the bumper painting jig of the present invention has a box-shaped masking jig, the back surface of the bumper can be easily masked by placing the bumper in a predetermined position.

Furthermore, a set confirmation member is installed upright on the box-shaped masking jig, and this member simultaneously masks, for example, the license mounting hole of the bumper. etc. and the upper end of the set confirmation member below are in the specified positional relationship with almost no gap, and the bumper is placed in the specified position on the painting jig without creating a large gap. is confirmed.

[Example] Next, the bumper painting jig of the present invention will be explained in more detail based on the drawings.

Fig. 1 is a perspective view showing an example of the bumper painting jig of the present invention, Fig. 2 is a vertical cross-sectional view of the bumper painting jig shown in Fig. 1 with a bumper placed thereon, and Fig. 3 is a different set confirmation member. It is a partial perspective view which shows an example.

As shown in FIG. 1, the bumper painting jig of the present invention (
1) includes a support frame (2) on which the bumper of the automobile is placed, a box-shaped masking jig (3) provided on the part of the support frame (2) on which the bumper is placed and used to mask the back side of the bumper, and the box. The masking jig (3) has a set confirmation member (4) attached to the inner surface thereof and erected at a position for masking an opening formed in the bumper. Note that side box-shaped masking jigs (3a) are provided on both sides of the box-shaped masking jigs (3) in the lateral direction.

In particular, in the bumper painting jig (1) shown in Figure 1,
The support frame ('2J) has a front bumper ffi1 part (2a) and a rear bumper mounting part (2b) for placing the front bumper and the rear bumper part side by side.

The box-shaped masking jig (3) is attached to the front bumper mounting part (2a
), but the front bumper mounting part (2a
) and the rear bumper mounting portion (2b), or may be provided on both.

In the bumper painting jig (1) of the present invention shown in FIG. 2, a front bumper (6) is placed on a front bumper placement portion (2a) of a support frame (2).

Masking tapes (5
) is pasted thereon, while the back side is masked by contacting the peripheral edge of the box-shaped masking jig (3). In addition, the license mounting hole (7) on the front bumper (6)
A set confirmation member (4) is erected at a position that covers from below.

In FIG. 2, the front bumper (6) is placed in a predetermined position without forming a large gap with the box-shaped masking jig (3). This can be confirmed by simply checking from the front side that the set confirmation member (4) covers the license attachment hole (sword) of the front bumper (6) without a large gap.

Furthermore, as shown in FIG. 3, the set confirmation member (4)
A protrusion shaped to fit into the corresponding bumper opening (
4a) not only makes it easier to visually confirm the set position as described above, but also makes the masking effect for the opening even more reliable.

In this way, by setting the front bumper (6) while looking at the license attachment hole (7) and the setting confirmation member (4), incorrect setting position can be easily prevented. Therefore, when painting the rear bumper 00 set on the rear bumper mounting part (2b), there is no possibility that the painting robot (old) will interfere with the front bumper (6).

Note that the same effect can be obtained even if the box-shaped masking jig (3) and the set confirmation member (4) are attached to the rear bumper mounting section.

In automotive bumper painting, an assembly line process is generally used in which bumpers are placed one after another on a conveyor, sent one after another to a paint booth and a drying oven, and the bumpers that come out are taken off the conveyor. Therefore, the jig of the present invention, which can easily set a bumper in a short time and without causing positional defects, achieves high work efficiency and stable high quality in bumper painting.

[Effects of the Invention] The present invention makes it possible to easily and accurately set a bumper in a predetermined position during bumper painting.

Therefore, high productivity can be achieved while reliably preventing masking defects caused by poor positioning and interference between the painting robot and the pumper.
