[0001] The present invention relates to a vertical transfer device for a robot, and more particularly to a vertical transfer device for a robot, which comprises a fixture, an upper up-down boom and a lower up-down boom, So that the height of the entire gantry equipment can be reduced by making the three-stage vertical transfer possible.

Generally, in the gantry robot, the vertical transfer device moves the moving part upward and downward from the fixing part in order to move the welding articulated robot up and down, so that the joint part between the fixing part and the moving part must be firmly connected.

Such a vertical transfer device conventionally used will be described in detail in the Registration Practical Utility Bulletin No. 20-0159578.

That is, a feature of the conventional vertical transfer device is that a vertical transfer device of a gantry robot for vertically moving a multi-joint robot has an opening having a receiving space therein, and a gravity acting direction And a ball nut that is engaged with a ball screw at the center of the center of gravity so that the gravity of the ball screw can be reduced by the rotation of the ball screw, A vertical transfer device of a gantry robot having a ball screw including a movable part coupled with a fixed part so that the movable part can be selectively moved in the direction opposite to or opposite to the direction of the vertical movement.

In the conventional vertical conveying apparatus having a ball screw as described above, since it has to be raised to the upper part of the gantry by the length of the up-down boom, there is a problem that sufficient free space for the boom is secured in the upper part of the can.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a vertical transfer device using three stages of motors and pinion gears, Stage vertical conveying device which is capable of providing a three-stage vertical conveying device.

According to an aspect of the present invention, there is provided a vertical transfer device including an up-down boom for performing a welding operation using a robot, the vertical transfer device comprising: a fixture for fixing a vertical transfer device; a rack gear formed at one side thereof; A lower up-down boom having a top up-down boom, a rack gear formed at one side thereof and inserted into the upper up-down boom, and a first pinion installed at the fixture and connected to the rack gear of the upper up- And a second pinion gear provided at a lower end of the upper up-down boom and connected to a rack gear of a lower up-down boom, the upper pin down gear having a motor, The up-down boom can be moved up and down, and the second pinion gear connected to the rack gear of the lower up-down boom The up-down due to the lower boom about the vertical three-stage feeding device characterized in that to enable the vertical transfer in three by so that it can be moved up and down.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a vertical transfer apparatus equipped with an up-down boom for performing a welding operation using a robot. The vertical transfer apparatus includes a fixed structure for fixing a vertical transfer device, A lower up-down boom formed with a rack and a rack gear formed at one side thereof and inserted into the upper up-down boom, a motor provided at the upper part of the upper up-down boom, And a second pinion gear provided at a lower end portion of the upper up-down boom and connected to a rack gear of a lower up-down boom, the motor being provided with a first pinion gear connected to a rack of the upper up- The rotation of the pinion gear allows the upper up-down boom to move up and down, and the rack gear of the lower up- So that vertical transfer can be performed by allowing the lower up-down boom to move up and down due to the rotation of the connected second pinion gear.

The effects of the present invention, which can be expected from the above-described configuration and operation, are as follows.

The lower up-down boom can be inserted into the upper up-down boom. Thus, when the boom is raised to the maximum, there is no need for a large space above the gantry.

1 is a sectional view showing a three-stage vertical transfer device according to the present invention,
Fig. 2 is a schematic view showing the operation of the three-stage vertical transfer device of the present invention in a step-by-step manner.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

1 is a cross-sectional view showing a three-stage vertical transfer device according to the present invention. 1, the present invention is characterized in that a first pinion gear 22 is provided on a fixed structure 10, and the first pinion gear 22 includes a speed reducer 23 and a motor 24, Rotation and deceleration rotations are possible.

The upper up-down boom 20 is formed with a rack gear 21 on its side and the rack gear 21 is adapted to engage with the first pinion gear 22. The upper up- And a boom having a size smaller than that of the upper up-down boom can be inserted into the space.

The second pinion gear 32 is provided at the lower end of the upper up-down boom 20. The second pinion gear 32 includes a speed reducer 33 and a motor 34 so that accelerated rotation and decelerated rotation . The lower up-down boom 30 is constructed to be inserted into the upper up-down boom 20, and the upper up-down boom 20,

Likewise, the rack gear 31 is formed on the side surface so as to be engaged with the second pinion gear 32.

 The welding robot 40 is coupled to the lower end of the lower up-down boom 30. The first pinion gear 22 and the second pinion gear 32 are operable to control the vertical movement of the robot. can do. Hereinafter, the operation of the present invention will be described in detail in connection with the drawings. FIG. 2 is a diagram illustrating the operation of the three-stage vertical transfer device in accordance with the present invention in a stepwise manner. The upper and lower up-down boom 20 and the upper-down boom 30 are maximally raised, The boom 20 and the lower up-down boom 30 are all shown in a descending order.

Up and down of the boom is controlled by the rotation of the first pinion gear 22 and the second pinion gear 32 so that the rack gears of the up-down boom, which are respectively engaged with the first pinion gear 22 and the second pinion gear 32, The upper and lower up-down boom 20 and the lower up-down boom 30 can vertically ascend and descend while the first and second up and down booms 21 and 31 move.

Meanwhile, as shown in the figure, when the upper and lower up-down booms rise to the maximum, the lower up-down boom is inserted into the upper up-down boom, so that the upper space due to the rise of the up- , The lower up-down boom inserted in the upper up-down boom descends and can be taken out of the upper up-down boom and the maximum descending length can be longer.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
