Description

Nest die exchanger {EXCHANGING APPARATUS FOR NEST DIE}

The present invention relates to an automobile assembly line, and more particularly to an automobile panel production line for producing a panel of an automobile by a press.

In general, automotive panel production line uses a press to forge blanks to produce panels.

The produced panel is loaded into the nest die and transferred to the next process.

Here, the nest die is different in size and shape of the panel according to each vehicle type, so a tool that can adjust the gap according to the size of the panel is inserted on the nest die, and then the panel is loaded on the tool.

In addition, in order to transfer panels of different sizes, the hanger mast for installing a vacuum cup to absorb the panels must be replaced.

However, the nest die as described above has to be changed by the operator every time the tool inserted on the nest die is changed.

Therefore, there is a problem in that productivity decreases because the line must be stopped for a time when an operator changes a tool.

In addition, since the operator must manually replace the tool on the nest die by hand, there is a problem that a safety accident may occur due to malfunction of the robot.

Accordingly, the present invention has been made to solve the above problems, to provide a nest die exchange apparatus for exchanging the nest die including the tool without the operator need to replace the tool.

In order to achieve the above object, the present invention, in the nest is formed on the top surface, the tool is inserted into the hole, the panel is mounted on the tool, the coupling for coupling the nest die and the robot for transporting the panel It provides a nested die exchange apparatus comprising a means.

Here, the coupling means is a cup having an upper opening on the top of the nest die and a hemispherical groove formed on the inner circumferential surface, and a rod installed on the robot, having a flange formed at the tip, and an air inlet pipe formed to correspond to the hemispherical groove of the nest die on the outer peripheral surface of the flange. And, it is characterized in that the ball is inserted into the air inlet pipe and installed to be movable to the hemispherical groove.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view schematically showing a nest die exchanger according to the present invention, Figure 2 is a front view showing a coupling means of the nest die exchanger according to the present invention.

According to the above drawings, the nest die 10 has a plurality of holes formed therein, and the tool 12 is inserted into the hole so as to adjust the gap according to the size of the panel, and the panel is loaded on the upper part of the tool 12. .

Nest die exchange apparatus according to a feature of the present invention is characterized in that the coupling means for coupling the robot 14 and the nest die 10 for loading the panel.

The coupling means includes a cup 18 having an upper opening on the upper surface of the nest die 10 and a hemispherical groove 16 formed on an inner circumferential surface thereof, and a flange 20 formed at the front end thereof with a flange 20 formed at the front end thereof. The air inlet pipe 22 is connected to the hemispherical groove 16 of the nest die 10 on the outer circumferential surface of the rod 24 and is inserted into the air inlet pipe 22 and moves to the hemispherical groove 16. It consists of a ball 26 installed to be possible.

The cup 18 has an upper opening so that the flange 20 of the rod 24 can be inserted therein, and a hemispherical groove 16 is formed so that the ball 26 can be inserted into the inner circumferential surface thereof so that the upper surface of the nest die 10 can be inserted. Is installed on.

Such a cup 18 is preferably installed at the center of gravity of the nest die 10 so that the center of the nest die 10 can be maintained when the robot 14 lifts.

The rod 24 has a flange 20 formed at the tip thereof, and an air inlet pipe 22 corresponding to the hemispherical groove 16 of the nest die 10 is connected to the outer circumferential surface of the flange 20 so that the robot 14 It is fixedly installed.

Here, the air inlet pipe 22 is installed to communicate with the compressor inside the rod 24 to receive the high pressure air from the compressor.

The ball 26 is inserted into the air inlet pipe 22 and is inserted into the hemispherical groove 16 by compressed air, thereby coupling the cup 18 and the rod 24.

The ball 26 is installed so that the ball 26 does not escape from the air inlet pipe 22 when compressed air is not supplied to the air inlet pipe 22.

The operation of the nest die exchange apparatus according to the present invention as follows.

Before replacing the panel with other models, prepare the nest die 10 for the size of the panel to be photographed on the tool stand.

When the production of the last panel is finished, the existing hanger mast fixed to the robot 14 is removed and moved to the tool stand.

Next, the robot 14 is moved to move the existing nest die 10 to the tool stand using the nest die exchanger.

Here, the replacement of the nest die 10 using the nest die exchanger according to the characteristics of the present invention is as follows.

The robot 14 is moved to move the rod 24 fixed to the robot 14 to the upper portion of the cup 18, and then the rod 24 enters the inside of the cup 18.

When the rod 24 enters the inside of the cup 18, the compressed air is supplied to the air inlet pipe 22 to form a ball 26 inserted into the air inlet pipe 22 on the inner circumferential surface of the cup 18. Insert into hemispherical groove (16).

When the ball 26 is inserted into the hemispherical groove 16, the cup 18 and the rod 24 are integrally coupled so that the robot 14 is raised to lift the nest die 10.

Next, after the nest die 10 is moved to the tool stand, when the compressed air supplied to the air inlet pipe 22 is blocked, the ball 26 comes out of the hemispherical groove 16 of the cup 18.

When the ball 26 is pulled out, the rod 24 and the cup 18 are separated, so the robot 14 is moved upwards, and then the new nest die 10 placed on the tool stand is moved in the same manner as when the ball is taken out. The replacement work of the nest die 10 is completed.

When the replacement of the nest die is completed, a new hanger mast is installed on the robot and the panel is pressed.

As described above, the nest die exchange apparatus according to the present invention exchanges the entire nest die so that the tool does not need to be plugged into the nest die, thereby saving time and improving productivity.

In addition, there is no need to plug in the tools one by one to prevent workers from accidents,
