Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a vehicle door removing device in an automobile assembly line.

[0002]

[Prior Art]

 In the assembly line of automobiles, when the assembly process is completed and the assembly line is entered, the door is temporarily removed for fitting inside the body, and the door is reattached at the point where the interior fitting is finished.

As shown in FIG. 2, a conventional door removing work is performed by mounting a door support base 4 with casters on a carriage 3 moving on a floor 2 beside a conveyor 1 on which a body B is transported. An operator rides on the dolly 3, loosens the hinge bolts with a hand tool, removes the door 5 from the body B, supports it on the door support 4, and moves the dolly 3 to a hanger conveyor (not shown) to move the door. The door 5 is moved from the support base 4 to the hanger conveyor, and is transported to the assembly station where it is attached to the body B again by the hanger conveyor.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional method, it is an inefficient manual removal work, and the worker has to work on the moving trolley 3 and there is a problem in safety.

An object of the present invention is to provide a vehicle door removing device that solves the above-mentioned conventional problems.

[0006]

[Means for Solving the Problems]

 The gist of the present invention for achieving the above object is a conveyor for carrying a body of an automobile to which a door is attached, and a body positioning device for stopping and positioning a body carried by the conveyor at a door removal position. It is arranged so that it can move back and forth on both sides of the body positioned by this body positioning device, and has a door fixing device, a door engaging claw, a door gripping tool, and a bolt loosening device, and is connected to the robot arm. It consists of a door removal device.

[0007]

[Action]

 With the above configuration, it is possible to automatically perform all operations from the door removal to the hanger conveyor for transporting the door to the subsequent process.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 10 denotes a pit, which is provided with a conveyor 11 for carrying the body B, and a body positioning device 12 for stopping and positioning the body B carried by the conveyor 11 at a door removal position.

A support base 14 is fixedly installed on the floors 13 on both sides of the body B positioned by the body positioning device 12, and can move forward and backward on the support base 14 and engage with an arm of a 6-axis robot 18. A combined door removal device 15 is arranged. The door removing device 15 is composed of a door gripping tool 16 having a door fixing device 16a, a bolt loosening device 17, and a door engaging claw 19. Further, even if the door 5 is displaced from the fixed position, it is connected to the robot arm through a robot wrist 18a having a floating function that allows the door 5 to be opened reliably and a rotating function that allows the door 5 to freely rotate.

In FIG. 1, reference numeral 20 is a hanger conveyor, which conveys the removed door 5 to the re-assembly position. Reference numeral 21 denotes a wax coating device for coating the door 5 with wax during transfer to the hanger conveyor 20.

Since the structure of the present invention is as described above, the body B is conveyed by the conveyor 11 and positioned at a predetermined position by the body positioning device 12 at the door removal position. On the other hand, the door dismounting device 15 is moved forward on the support base 14 toward the side surface of the body B by the robot 18, and the door is engaged with the door engaging claw 19 to move the door 5 at a predetermined angle (about 69 °). Open up to.

Next, the door fixing device 16a is raised to fix the door 5 opened to the predetermined angle, and the bolt loosening device 17 enters the door hinge portion. At this time, the position of the body B is measured by a visual sensor or a distance sensor built in the bolt loosening device 17 to calculate the amount of displacement, and the hinge bolt position is corrected based on the calculated amount of displacement to adjust the hinge. Correctly match the bolt and loosen the hinge bolt.

In the process of loosening the hinge bolt, the door gripping device 16 is moved to the door inner side, and the door gripping device 16 grips the door 5. Then, after confirming that all the hinge bolts have been loosened, the door removing device 15 moves backward to remove the door 5 from the body B, moves to the wax applying device 21, and the wax applying device 21 applies wax to the door hinge surface. Apply.

The door 5 on which the wax application is completed is transferred to the hanger conveyor 20 by the door removing device 15, the door removing device 15 is returned to its original position after the transfer, and the body B is transferred to the next step by the conveyor 11. Complete the export door removal cycle.

[0015]

[Effect of the device]

 As described above, according to the present invention, the body of the automobile to which the door conveyed by the conveyor is attached is positioned by the body positioning device at the door removal position, and the doors are placed on both sides of the body positioned by the body positioning device. The door removal device connected to the robot arm is arranged so that it can be moved back and forth, having an engaging claw, a door gripping tool, and a bolt loosening device. It is possible to automatically perform all the operations up to the hanger conveyor, and the door removal is automated in the automobile assembly line, which has the advantage of improving the production efficiency of automobiles.
