Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a vehicle window glass mounting device.

(Prior art) The car bodies assembled through the necessary welding process have some differences in construction, and the window glasses that are attached to the mounting frames of these car bodies also have sufficient dimensional accuracy. Not yet.

For this reason, in order to attach a window glass to a car body that has been transported through the required assembly process, two workers usually hold a jig that holds the glass by suction and position the glass with the mounting frame of the car body. While visually confirming the relationship, the windshield was installed to match each vehicle body.

However, this type of work not only requires a considerable amount of labor from the workers as they are dealing with heavy glass, but also, if the workers are unskilled or the two workers do not get along, it may be necessary to adjust the glass to fit the vehicle body. Quality control problems arise when the parts cannot be installed accurately.

(Purpose) The present invention was made in view of such problems,
The purpose is to provide a new device that allows a single operator to precisely mount a window glass in accordance with the vehicle body.

(Structure) In other words, in order to achieve the above object, the present invention includes a guide means disposed above the conveyance path of the vehicle body and perpendicular thereto, and a windshield held by traveling on the guide means. controllable mounting means for transferring and mounting the window glass toward the window glass mounting frame; imaging means for capturing at least the upper portions of both sides of the mounting frame in order to capture the positional relationship between the mounting frame and the transported window glass; and the imaging means an image means for projecting an image captured by the window glass; and a correction operation means for acting on the mounting means to slightly adjust the means in order to correct the positional relationship between the window glass and the mounting frame, and the image is projected on the imaging means. The present invention provides a device for attaching a window glass to a vehicle body with high accuracy by slightly correcting the attaching means using a correcting operation means while visually observing the image.

Therefore, details of the present invention will be explained below based on illustrated embodiments.

The drawing shows one embodiment of the present invention, and reference numeral 1 in the drawing indicates a gate-shaped rail that is arranged to straddle the conveyor 2 and be perpendicular to it. Two television cameras 3, 3 capable of capturing both upper sides of the glass mounting frame 21 of the vehicle body 20 stopped on the conveyor belt 2 are installed, and the images captured by these cameras will be described later. It is configured to display on two cathode ray tubes 17, 17 on the control panel 16.

Reference numeral 4 denotes a window glass mounting robot arranged on the gate-shaped rail 1, and a robot 4, which is driven by a motor (not shown) and runs on the rail 1 in the A first support 8 is suspended, which is controlled by a controller 7 for controlling the axial direction, and a fork that is controlled by a controller 9 for controlling the Y-axis is attached to the support 8. A second support 10 is attached to the rod end of the cylinder 11 so as to be movable parallel to the conveyor belt 2.

This second support 10 also has a jig 12 for suctioning and holding the window glass 22 at the rod end.
The pressing cylinder 13 with attached is the controller 1
4 so as to be rotatable around its axis, and a controller 15 so as to be swingable up and down.

On the other hand, a control panel 16 disposed near the portal guide 1 operates the robot 4 based on the relative positional relationship between the mounting frame 21 and the window glass 22 shown on the two cathode ray tubes 17, 17. The operation panel surface has a correction operation for finely adjusting the window glass 22 held by suction to the jig 12 at a position directly in front of the mounting frame 21 via each controller 7, 9, 14, 15. Button 18 and
Press the modified window glass 22 onto the cylinder 1.
An operation completion button 19 for pressing the mounting frame 21 with the button 3 is provided.

Next, the window glass 22 by the above-mentioned device is
The positioning and mounting operation will be explained below.

When the vehicle body 20 conveyed by the conveyor belt 2 stops at a predetermined mounting position, the traveling main body 5, the first support body 8, and the second support body 10 are connected to a motor (not shown) and cylinders 6, 11, respectively. The second support body 10 is driven to move by a preset amount in the X-axis direction, Z-axis direction, and Y-axis direction.
The upper pressing cylinder 13 rotates to a preset angle of inclination, and then protrudes a rod with a jig 12 at its tip to hold the window glass 22, which is suctioned and held by the jig 12, just in front of the mounting frame 21 of the vehicle body 20. transport to position.

By the way, as mentioned above, the car bodies 20 assembled through the required processes have some differences in the quality of construction, and the window glass 22 is not made with sufficient precision, so this automatic transfer is not possible. Windshield 22 fed by the action
do not necessarily have an accurate positional relationship with the mounting frame 21 of the vehicle body 20, and in this state, the two television cameras attached to the gate-shaped rail 1 to capture images of both upper sides of the mounting frame 21. Two cathode ray tubes 17, 17 on the operation panel 19 caught by 3, 3
will be displayed on the screen.

Therefore, the operator uses the images projected on these cathode ray tubes 17, 17 based on the X and Y reference lines 17a, 17b drawn on the cathode ray tube 17, or the cursor, etc., when making corrections in the vertical direction, for example. To adjust the position of the first support 8 in the Z-axis direction, press one of the correction operation buttons 18 (Fig. 2) with an arrow pointing upward or downward, and operate the cylinder 6 via the controller 7. If you want to make fine adjustments to the left and right, press the correction operation button 18 with a sideways arrow to slightly move the traveling body 5 back and forth. Also, if you want to correct the inclination, use the correction operation buttons on both sides of the top. 18 to slightly rotate the pressing cylinder 13 in the axial direction to accurately position the window glass 22 corresponding to the mounting frame 21 of each vehicle body 20, and finally press the correction completion button 19. is pressed to operate the pressing cylinder 13 to press and fix the window glass 22 to the mounting frame 21.

As described above, according to the present invention, the positional relationship between the vehicle body mounting frame and the transported window glass is projected on the video means, and based on this, the windshield mounting means is adjusted by the correcting operation means. By correcting the slight movement, it eliminates the worker's hand misalignment that occurs when handling heavy objects, and also makes use of the worker's excellent experience to install window glasses on the mounting frames of car bodies that are individually constructed. This allows for highly accurate installation, resulting in stable quality and significant labor savings.
