Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hood opening/closing jig in an automobile painting process. More specifically, the present invention relates to a jig for opening and closing the hood of an automobile by a robot in a painting process.

[Prior Art] In the current automobile painting process, while the automobile to be painted is moved within a painting booth, a painting robot first paints the inner surface of the automobile and then paints the outer surface of the automobile.

When painting the interior of a car, it is necessary to open the front hood (hereinafter referred to as the hood), but in current painting factories, the factory equipment is such that this hood opening process is automatically done by robots, that is, unmanned. Designed.

Therefore, conventionally, cars that enter the paint booth are equipped with an arm to open the hood using a robot.
It is fixed to the hood so that it protrudes forward with the hood slightly open.

The reason why the hood can only be opened slightly with the arm protruding forward is that if it is opened wide, the distance between the hood and the paint gun will be smaller.
This is due to the fact that the distance between the front panel and the paint gun is greatly different, resulting in subtle differences in the finish of the paint. For the above reasons, in the process of painting the exterior surface of an automobile, it is essential to paint the front hood of an automobile as close to a closed state as possible.

In recent years, due to the diversification of automobile designs, designs in which the front end panels of automobiles protrude significantly forward have begun to be adopted.

It is not desirable to attach a conventional arm for opening and closing the hood to such a newly designed automobile.

This is because the protrusion of the front end panel gets in the way, and the conventional arm cannot be installed unless the hood is wide open, and if this is done, the color of the paint will be different between the hood and the front panel. This is because such problems arise.

[Problem to be solved by the invention] Therefore, the present invention is capable of keeping the hood almost closed during the exterior painting process, even in newly designed automobiles in which the front end panel protrudes forward. To provide an opening/closing jig which can be opened automatically using conventional factory equipment.

[Means for Solving the Problems] The present invention is a hood opening/closing jig in an automobile painting process, which comprises a primary side jig attached to the body and a secondary side jig attached to the hood. The primary side jig includes (a) a base frame attached to the body so as to extend in the vertical direction, (b) an operating lever, and (c) extending along the base frame by operation of the operating lever, The secondary jig consists of a rod that rotates around its axis, and (d) an engager attached to the rod, and (e) a base attached to the back surface of the hood, and (f) a base attached to the base. It is rotatably mounted in a horizontal plane,
It is characterized by comprising an arm that is engaged with and rotated by the engager of the primary side jig.

[Operation] When using the jig of the present invention, the primary side jig is attached to the body, and the secondary side jig is attached to the back side of the hood. When the control lever is not operated, the rod is not extended, so the overall length is short and the hood can be kept closed.

When the operating lever is operated, the rod rotates while extending, so the hood is lifted, the engager of the primary jig rotates the arm of the secondary jig,
Make the arm protrude in front of the hood. In this state, the robot in the factory equipment can lift the arm and open the hood.

[Example] Next, embodiments of the present invention will be described.

FIG. 4 is a perspective view showing the opening/closing jig after rotational operation, and FIG. 5 is a perspective view showing the opening/closing jig attached to an automobile.

In Fig. 5, A is an opening/closing jig, B is a car,
C is the hood and D is the front end panel.
The opening/closing jig A consists of a primary side jig 1 and a secondary side jig 2, and is designed to be installed in the engine room.

In addition, car B in which jig A of the present invention is used
As shown in FIG. 1, the front end panel D protrudes in front of the hood C in the closed state, and the surface of the hood C and the upper surface of the panel D are substantially flush with each other.

Next, the structure of the opening/closing jig A will be explained based on FIGS. 2 to 4.

In FIG. 2, 1 is a primary side jig, and 3 is its base frame. The base frame 3 is a frame-like structure with supporting plates 4 and 5 protruding laterally at the upper and lower ends, and a mounting plate 6 is attached to the upper end and a locking fitting 7 is attached to the lower end. A rod 10 passes through the upper and lower support plates 4 and 5. Rod 10 is the third
As shown in the figure, it consists of an inner rod 11 and an outer rod 12, both of which cannot move relative to each other in the axial direction, but the outer rod 12 can rotate around the inner rod 11. A guide groove 13 is formed on the outer peripheral surface of the external rod 12, and the upper part of the guide groove 13 runs along the axial direction, and the lower part is curved. The tip of a pin 14 fixed to the base frame 3 is fitted into this guide groove 13. Further, a bracket 15 is fixed to the upper end of the external rod 12 so as to protrude laterally, and an engaging element 16 having a fork-like shape is erected at the tip of the bracket 15. Furthermore, a push stand 17 is attached to the upper end of the internal rod 11.

The elevating mechanism of the rod 10 will be explained based on FIG. 21 is a bracket fixed to the support plate 5, and 22 is a bracket fixed to the internal rod 11. Links 23 and 24 are connected by pins between the brackets 21 and 22, and an operating lever 25 is fixed to the upper end of the link 24. When the operating lever 25 is rotated from the lower position shown by the chain line to the upper position shown by the solid line, the rod 1
0 is pushed upwards. When operated in this way, internal rod 11
extends upwardly, and the external rod 12 pivots about its axis as shown by arrow r in FIG.

Next, the secondary jig 2 will be explained based on FIG. 2 again.

E is a U-shaped striker fixed to the back side of the hood C.

The base portion 30 of the secondary side jig 2 is composed of a connecting portion 31 that is connected to the striker E and a support portion 32 that rotatably supports the arm 33, and both are fixedly connected. The connecting portion 31 is a box-shaped member that accommodates the striker E and can be connected with the pin 34 to prevent the striker E from coming off.
The support portion 32 rotatably pivots the base of the arm 33, so that the arm 33 can rotate within a horizontal plane. The arm 33 includes a main body 35 and an engaging arm 36 projecting laterally from the middle thereof. This engaging arm 36 is a member that engages with the engaging element 16 of the primary side jig 1 and rotates the arm 33.

The arm 33 in the above secondary jig 2 is 1
When the rod 10 of the next jig 1 is in the lowered position as shown in FIG. 2, it is oriented laterally, but as shown in FIG. ), when the engager 16 rotates in the direction of arrow R, the arm 33 also rotates in the direction of arrow R and projects forward.

Next, a method of using the opening/closing jig A of the present invention will be explained based on FIG.

The primary side jig 1 is attached to the body side by attaching the mounting plate 6 to the radiator support F of the automobile body with bolts 26 and inserting the locking metal fitting 7 into the engagement hole of the balance panel G. Secondary side jig 2
is attached to the back surface of the hood C by connecting the base 30 to the striker E with a pin 34.

Next, when entering the inner surface painting process, the operating lever 25 is pulled up from the chain line position to the solid line position using the hook H of the automatic work robot installed in the coating booth.

As a result, the rod 10 rotates while rising, so that the hood C is pushed up slightly and the arm 33 projects forward with the hood C open. In this state, the arm 33 is located above the front end panel D and can be easily hooked onto the hook H.

Therefore, as shown in the diagram, arm 3 is attached with hook H.
3 and pull it up to open the hood C and move on to the interior painting process of the car.

In the external painting process, the rod 10 of the primary side jig 1
is kept in a withdrawn state. In this case, the hood C is kept closed, as shown by the chain line, and its upper surface is substantially flush with the upper surface of the front end panel D. Therefore,
In the external surface painting process, the distance between the hood C and the paint gun and the distance between the front panel and the paint gun are approximately equal, so that uneven coating and differences in color do not occur.

In the above embodiments, the example of opening the front hood of an automobile was explained, but the jig of the present invention can be used not only for opening and closing the front hood but also as a jig for opening and closing a trunk lid or a back door.

The term "hood" as used in the utility model claims of this specification includes not only the front hood of an automobile but also all lids such as trunk lids and back doors.

[Effect of the invention] According to the invention, in the automobile painting process,
The hood can be easily opened automatically. Further, since there is no color unevenness or difference in tone between the hood and the adjacent panel, the coating quality is improved.
