JPH09276766A - Adhesive applicator for automotive door - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make it possible to evenly apply an adhesive at a specified width on an automotive door by disposing a stopper for correcting the posture of the automotive door by coming into contact with the automotive door in a position where the automotive door inclines and arrives when a hanger holding the automotive door is pushed by a pusher. SOLUTION: The automotive door 2 is held by the hanger 4 in the state of allowing its slight movement and is sent by a transporting rail 1; thereafter, the door is subjected to the application of the adhesive by a coating applicator robot 3. At this time, the hanger carried to the coating application position is pushed by the pusher 7 toward the coating applicator robot 3 and the automotive door 2 held by the hanger 4 is inclined to the extent that the applied adhesive does not sag. At this time, the stopper 8 for correcting the posture of the automotive door 2 by coming into contact with the automotive door 2 is disposed in the position where the automotive door 2 inclines and arrives. As a result, the automotive door 2 is made to attain always the stable posture and the correct application of the adhesive is made possible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive application device for applying an adhesive to an automobile door by an application robot in an automobile door assembly line.

[0002]

2. Description of the Related Art A door for an automobile has a resin sheet covering an inner part having an opening in a pre-process of assembling an interior material after assembling a window elevating device or the like so that dust and water do not enter an inner space. The periphery is sealed with an adhesive (for example, a butyl-based adhesive) (Japanese Utility Model Publication No. 3-40386).

The sealing work by the apparatus of the above publication is to separate an automobile door sent from a dedicated door assembly line from a transport rail, transfer it to a work positioning device, and apply an adhesive by a coating robot. Thus, there is a problem that the mechanism for positioning the door before coating becomes complicated and the device becomes a large-scale device.

As an apparatus for applying an adhesive with a simpler mechanism than this, there is an apparatus shown in FIG. This is for applying the adhesive by the application robot 3 without keeping the automobile door 2 sent by the transport rail 1 of the dedicated door assembly line from the transport rail 1.

The transport rail 1 transports a hanger 4 holding an automobile door 2 in a suspended state, and a guide rail 6 for rolling a guide roller 5 under the hanger is provided below the transport rail 1. .

As shown in FIG. 5, the automobile door 2 is placed in a holding groove 4a provided in the lower portion of the hanger 4, and is slightly moved by the pawls 4b and 4b on both sides, which is restricted from lateral movement. Is held on the hanger 4 in a state in which is allowed.

A pusher 7 using an air cylinder or the like is provided at a position facing the coating robot 3, and when the hanger 4 holding the automobile door 2 reaches the coating position.
The hanger 4 is pushed toward the coating robot 3, and the automobile door 2 is tilted to such an extent that the coated adhesive does not drip from the door.

As described above, with the vehicle door 2 tilted, the coating robot 3 automatically applies the adhesive by moving the coating gun 3a along the coating target point.

[0009]

In the step of applying the adhesive, the automobile door 2 is held by the hanger 4 in a state where some movement is allowed. Therefore, when the hanger 4 is tilted by the pusher 7, as shown in FIG. 6, the vehicle door 2 may rattle in the hanger and take an inclined posture. At this time, the distance between the door application surface and the application gun 3a was varied, and the adhesive could not be applied sufficiently, which necessitated reworking later.

Therefore, the object of the present invention is to make it possible to apply the adhesive sufficiently by keeping the automobile door in a stable posture at the time of the applying operation by the applying robot. And

[0011]

According to the present invention, there is provided a vehicle door adhesive coating apparatus, which is adapted to push a vehicle when a hanger, which is hung on a carrier rail and holds the vehicle door, reaches an adhesive coating position. Push the hanger, tilt the car door held by the hanger so that the adhesive to be applied does not hang down, and move the application robot's application gun along the application target point on the door to apply the adhesive. The device is characterized in that a stopper for hitting the vehicle door and correcting the posture of the vehicle door is provided at a position where the vehicle door is inclined and reaches when the hanger is pushed by the pusher.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION One embodiment of the present invention is shown in FIGS.
Will be described.

In FIG. 1, reference numeral 1 is the transfer rail for moving a hanger 4 holding an automobile door 2 in a suspended state, and 3 is the coating robot having a coating gun 3a. Reference numeral 5 denotes the guide roller provided on the lower part of the hanger, which is guided by a guide rail 6 provided below the transport rail 1 to roll. Reference numeral 7 shown in FIG. 2 is the pusher provided so as to face the coating robot 3, and pushes the hanger 4 carried to the coating position toward the coating robot 3 to hold the hanger 4 on the vehicle door. Tilt 2 so that the applied adhesive does not sag.

Reference numeral 8 denotes a stopper newly provided according to the present invention, which is provided at a position where the vehicle door 2 is inclined and reaches when the hanger 4 is pushed by the pusher 7.
The posture is corrected by hitting the automobile door 2. The stopper 8 makes the coating surface of the door 2 parallel to the moving surface of the coating gun 3a at a constant interval, and hits the door to correct the posture at a position where the movement of the coating gun 3a is not hindered. . In the illustrated example, the belt shape has a shape that follows the lower edge of the door that is out of the movement range of the coating gun, but it may have a shape that abuts the left and right edges of the door.

A protective material 9 such as a rubber tape is attached to the stopper 8 in order to prevent the door 2 from being scratched.

The adhesive applying device having the above structure pushes the door 2 against the stopper 8 by pushing the hanger 4 with the pusher 7 when the hanger 4 holding the automobile door 2 reaches the adhesive applying position. The application surface of the door 2 is kept parallel to the moving surface of the application gun 3a with a constant space. In this state, the coating is performed while moving the coating gun 3a along the coating target point, so that the coating width of the adhesive can be made constant and the coating can be performed evenly and sufficiently.

[0017]

According to the present invention, when the pusher 7 tilts the automobile door 2 held by the hanger 4 suspended on the transport rail 1 together with the hanger 4, the stopper 8 is provided.
Since the posture of the door 2 is corrected by the above, the distance between the application surface and the application gun 3a can be kept constant, and the adhesive can be applied with a constant width and evenly. Therefore, the subsequent reworking work becomes unnecessary and the production cost can be reduced.
