Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a coating jig for resin parts, which is used for baking coating together with the body of an automobile.

[Prior Art] As a conventional jig for coating resin parts, the one shown in FIG. 4 is known (see Japanese Patent Laid-Open No. 63-270571). That is, the conveyor vehicle 5 is on the conveyor 50.
1 is mounted on the carriage 51, and the columnar support legs 5 are attached to the carriage 51.
2, 52 are erected. A horizontal arm 53 is fixed to the upper ends of the columnar support legs 52, 52, and an inner recess 54a of a plastic bumper 54 is attached to the horizontal arm 53.
, A plurality of bumper support members 55 formed of foamed plastic are fixed.

In such a structure, after aligning the inner recess 54a of the plastic bumper 54 with the bumper support member 55,
The plastic bumper 54 is moved to a predetermined process together with the carrier truck 51 to perform baking coating.

[Problems to be Solved by the Invention] However, in such a conventional coating jig, the carrier truck 51 has columnar support legs 52, 52, a horizontal arm 53,
The bumper support member 55 and the like are provided, and the structure is used only for coating resin parts (plastic bumper 54). Therefore, in addition to the vehicle body carrier used for painting the vehicle body, the resin carrier vehicle 51 provided with the columnar support legs 52 and the like is required.
Equipment costs will increase.

Further, generally, in an automated coating line, management is performed for each carrier vehicle, and coating is performed on an object on the carrier vehicle while moving a plurality of processes. Therefore, when the resin-only carrier truck 51 such as the bumper 54 and the vehicle carrier truck are used together in this way, the resin component and the vehicle body on which the resin component is mounted are painted at different times,
It is not possible to accurately match the paint colors of both.

The present invention has been made in view of such a conventional problem as described above, and aims at reducing the facility cost and performing the coating so that the coating colors of the resin component and the vehicle body on which the resin component is mounted are accurately matched. An object of the present invention is to provide a coating jig for resin parts that can be used.

[Means for Solving the Problems] In order to solve the above problems, according to the present invention, it is possible to lock on a predetermined portion of a vehicle body that is placed on a carrier and moves through a plurality of coating processes and baking and drying processes. An arm portion having a support portion at one end, the other end being spaced from the vehicle body and being located in a peripheral space in a plan view of the vehicle body in a state where the support portion is locked to the predetermined portion; The receiving portion is provided at the other end, and is formed of a resin material and formed into a shape that substantially matches the lower surface of the resin component to be mounted on the vehicle body.

[Operation] In the above configuration, the support portion is locked to a predetermined portion of the vehicle body,
When the resin component is placed on the receiving portion, the resin component on the receiving portion is supported by the vehicle body via the arm portion, and as the carrier vehicle moves, the plurality of coating steps are performed integrally with the vehicle body on the carrier vehicle. And move the baking process. Therefore, it is possible to transfer the resin component to the coating process and the baking / drying process and apply the coating by using only the vehicle carrier for the vehicle body without using a separate carrier vehicle dedicated for the resin component.

In addition, generally, in an automated coating line, since control is performed for each transport carriage and coating is performed while moving multiple processes, resin parts are transported together with the vehicle body on the same transport carriage, and It is possible to paint with the car body at the same time. In this simultaneous coating, in the final coating process, which is the final coating process, for resin parts,
The same color as the car body is manually applied so that the end of the car body is sufficiently painted, and then the car body is automatically air spray painted. At this time, paint particles that are not atomized form dust and fall into the space around the vehicle body. However, since the receiving portion that supports the resin component is provided at the other end of the arm that is separated from the vehicle body and is located in the surrounding space in a plan view of the vehicle body, the dust is generated between the vehicle body and the resin component. It will not fall on the resin parts and will not adhere to the resin parts.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

That is, as shown in FIGS. 1 to 3, the coating jig 10 includes a receiving portion 11 and an arm portion 12.
Reference numeral 20 is a resin component, and 30 is a vehicle body assembled from steel.

The receiving portion 11 is a FRP resin obtained by impregnating a glass fiber base material with an unsaturated polyester resin and molding by a hand lay-up method, and the surface shape of the receiving portion is the lower surface of the resin component 20 to be mounted on the vehicle body 30. It is molded into a shape that substantially matches 21. Then, the receiving portion 21 of the resin component 20 is fitted and placed on the receiving portion 11.

The arm portion 12 is a round bar made of iron and has a predetermined length b, a hook-shaped support portion 13 is provided at one end, and the other end is fixed to the lower surface of the receiving portion 11 by FRP resin. When the support portion 13 is locked to a predetermined portion of the vehicle body 30 (a rear combination lamp mounting hole in this embodiment as described later), the receiving portion 11 is separated from the vehicle body 30 by b (about 250 m).
m) are separated from each other and are located in a peripheral space in a plan view of the vehicle body 30, that is, a space around the vehicle body 30 when viewed from above.
Is shaped to be substantially horizontal.

The resin part 20 is a part which is a part of the outer panel of the vehicle body injection-molded from a heat-resistant PP material having a heat distortion temperature of 150 to 160 ° C., and is painted in the same color as the vehicle body 30.
In this embodiment, it is a rear combination lamp finisher.

Next, the process of baking coating the resin component 20 using the coating jig 10 according to the present embodiment will be described.

(A) Step of setting on vehicle body As shown in FIG. 3, the coating jig 10 in which the resin component 20 is set in the receiving portion 11 in advance on the vehicle body 30 placed on the transportation dolly 40 as a transportation vehicle. The support portion 13 is locked. This locking merely hooks the support portion 13 in the rear combination lamp mounting hole. As a result, the resin component 20 is set substantially horizontally with respect to the vehicle body 30 with a predetermined gap b.

(B) Primer coating process The vehicle body 30 is moved to the coating booth by the conveyor, and the primer coating is performed on the resin component 20 together with the vehicle body 30 in the booth. This primer coating is electrically conductive,
This is done for the purpose of adhesion and rust prevention.

(C) Intermediate coating process This is a coating process performed for the purpose of adjusting the surface of the coating film and preventing pitching due to stone bounce, etc. In the same manner as (b) above, the resin component 20 as well as the vehicle body 30 can be coated. Done.

(D) Baking and Drying Step While the transport dolly 40 moves in the drying furnace at a constant conveyor speed, the vehicle body 30 and the resin component 20 are baked and dried at the same time. The ambient temperature in the drying furnace is about 170 so that the painted surface temperature of the car body 30 is 140 ° C. for 20 minutes to bake and dry.
It is set to ℃.

(E) Top coating process This is a coating process mainly for beautifying the appearance of the vehicle body, and the resin component 20 is manually operated to have the same color as that of the vehicle body 30 so that the ends thereof are sufficiently coated. Is done. Then, the vehicle body 30 is automatically air-sprayed.

(F) Baking and drying step Baking and drying are performed under the same conditions as in (d).

Next, the operation of the embodiment will be described.

(1) Action in baking / drying process The resin component 20 and the coating jig 10 are exposed to an atmospheric temperature of 170 ° C. in the baking / drying furnace for 20 minutes. However, the receiving portion 21 on the lower surface of the resin component 20 is placed in conformity with the receiving portion 11 of the coating jig 10 and is shielded from the high temperature atmosphere by the receiving portion 11 of the coating jig 10. However, the temperature rise is prevented because the entire resin component is not exposed. Moreover, since the thermal conductivity of the FRP material of the receiving portion 11 is smaller than that of the steel material, the temperature rise of the resin component 20 is prevented more than in the case of the jig in which the receiving portion 11 is formed of steel material.
Incidentally, the measured temperatures of the resin parts with and without the coating jig 10 are 160 ° C. and 168 ° C., respectively. Also,
The resin part 20 is made of a steel body 30 by the arm portion 12.
Since it is arranged apart from the above, the influence of radiant heat from the vehicle body 30 is small, and this also prevents the temperature rise of the resin component 20. Therefore, thermal deformation of the resin component 20 is prevented.

Further, since the resin component 20 is set in a substantially horizontal state by the jig 10, the receiving portion 11 is kept in a matched state under high temperature conditions, and thermal deformation due to tilting is prevented.

(2) Operation in the overcoating process As described above, the resin component 20 is manually operated to be painted in the same color as the vehicle body 30 so that the end portion of the resin component 20 is sufficiently coated, and then the vehicle body 30 is automatically coated. Air spray painted. At this time, the paint particles that are poorly atomized form dust and fall into the space around the vehicle body 30. However, since the resin component 20 is separated from the vehicle body 30 by the length b and is located in the surrounding space of the vehicle body 30 in a plan view, the dust falls into the interval of the length b and reaches the resin component 20. It is possible to avoid the adhesion of dust and improve the coating quality.

[Effect of the Invention] As described above, according to the present invention, the resin component on the receiving portion can be supported at a predetermined portion of the vehicle body that is placed on the carrier and moves through a plurality of coating processes and baking and drying processes. The resin parts can be moved to the painting process and the baking / drying process without preparing a carrier for the resin parts separately from the car carrier for the vehicle body, which can reduce the facility cost. .

In addition, generally, in an automated coating line, control is performed for each carrier truck and coating is performed while moving a plurality of processes. In such an automated line, the resin parts supported by the vehicle body on the carrier truck and the resin parts concerned. Since it is possible to paint on the vehicle body to which is mounted at the same time, it is possible to accurately match the coating colors of both.

Further, since the resin part is supported in the surrounding space in a plan view of the vehicle body, the resin part is sufficiently coated on the end portion in a specific painting process (top coating process) of the plurality of painting processes. After applying the same color as the car body by manual operation, the dust that has fallen does not adhere to the resin parts when the car body is automatically air spray painted. Therefore, it is possible to avoid the deterioration of the coating quality of the resin component while accurately matching the coating colors of the vehicle body and the resin component by simultaneous coating.
