It may also be arranged at intervals of 45 degrees or 90 degrees. In addition, the push button switch 500 may be coupled to the teaching handle 410 and fixed, or may be coupled to and fixed to the upper structure 100, the lower structure 200, and the support 300. In addition, the push button switch 500 may be a mechanical switch that can be operated by a physical pressing force, for example, may be a tact switch. Alternatively, various switches that can be pressed and operated by manipulation of the teaching handle 410 may be used. In addition, the push button switch 500 may be disposed such that the button portion being pressed faces the teaching handle 410.

Thus, the robot teaching device can be attached to the end of the robot to enable intuitive teaching of the user, and the robot can be controlled by transmitting the operation command directly to the robot through a mechanical switch. It is high and the manufacturing cost can be reduced.

In addition, the teaching handle 410 is the extension portion 420 protruding radially inward from the inner circumferential surface of the ring portion 430, the extension portion 420 is arranged spaced apart from each other in the circumferential direction, the support portion 300 ) Includes a first support portion 310 disposed radially inwardly surrounded by the extension portions 420, and the push button switch 500 is disposed within the extension portions 420 in the radial direction. The first switch 510 may be disposed between the side surface and the first support part 310, respectively.

That is, as illustrated, the teaching handle 410 may have a ring-shaped ring portion 430 formed in a shape in which a plurality of extension portions 420 protrude radially inward from an inner circumferential surface, for example, the extension portion 420. They may be arranged four spaced apart at intervals of 90 degrees in the circumferential direction. The free ends of the extension parts 420 may be formed to be spaced apart from each other without meeting each other. In this case, the support part 300 may include the first support part 310, and the first support part 310 may be disposed radially inward from the free end of the extension parts 420.

In this case, the first support part 310 may be formed in various forms, but in the drawings, four portions formed in the shape of an arc are formed in the form of being disposed at positions close to the free ends of each of the extension parts 420. In addition, the first support part 310 may extend in a form protruding upward from the upper surface of the lower structure 200, such that the lower structure 200 and the first support part 310 may be integrally formed. In addition, the push button switch 500 may include a first switch 510, and the first switch 510 may have an inner surface and a first support portion 310 of the free end portion of the extension portions 420 in the radial direction. The first switch 510 may be fixed to the first support part 310. In addition, the radially inner side surface of the free end portion of the extension portion 420 is formed as a flat surface, the first switch 510 and the extension portion 420 is in contact with the teaching handle 410 is not operated It may be arranged to be in a state or a finely spaced state.

Thus, when the user moves the teaching handle 410 in the x-axis direction or the y-axis direction, the extension 420 presses one first switch 510 to operate the switch to operate the teaching handle 410. In this way, the robot can be controlled to move the robot in a desired direction by receiving an operation signal of a switch operated by being pressed among the first switches 510. In addition, since the protruding bar-shaped extension part 420 is configured to press the first switch 510, the switch may be accurately pressed and operated according to the movement in the x-axis direction or the y-axis direction.

In addition, the support part 300 further includes a second support part 320 disposed between the extension parts 420 in the circumferential direction, and the push button switch 500 extends the circumferential direction. The second switch 520 may be further included between the side surfaces of the parts 420 and the side surfaces of the second support part 320.

That is, as shown, the support part 300 may include a second support part 320, and the second support part 320 may be disposed in the ring part 430 of the teaching handle 410 in the radial direction to be radial. As a result, the second support part 320 may be located in an area where the extension part 420 is formed. In addition, the second support part 320 may be formed in an arc shape, and may be formed between the extension parts 420, respectively, and both sides of the extension part (the surface facing the extension part) may be formed in the circumferential direction. Sides (faces facing the second support) may be spaced apart from each other. The push button switch 500 may be disposed between the extension part 420 and the second support part 320 in the circumferential direction. Accordingly, two second switches 520 may be disposed in proximity or contact with one extension part 420, such that eight second switches 520 may be provided in total. In this case, the second switch 520 may be disposed such that the button portion that can be pressed toward the extension portion 420 or in contact with the extension portion 420, and the second switch 520 is the second support portion 320. It can be coupled to and fixed to.

Thus, when the user rotates the teaching handle 410 about the z-axis, the circumferential side of the extension 420 of the teaching handle 410 presses the second switches 520 to operate the switch. The manipulation of the teaching handle 410 may be sensed, and thus, the robot may be controlled to rotate in a desired direction by receiving the operation signals of the switches operated by being pressed out of the second switches 520. In addition, since the protruding bar-shaped extension part 420 is configured to press the second switches 520, the switch may be operated correctly according to the rotational direction about the z-axis.

In addition, it may further comprise a fourth switch 540 disposed between the inner surface of the ring portion 430 of the teaching handle 410 and the second support portion 320 in the radial direction.

That is, as shown, the fourth switch 540 may be provided between the ring portion 430 and the second support portion 320 of the teaching handle 410, and the inner circumferential surface and the second support portion of the ring portion 430 may be provided. Fourth switch 540 may be provided between the 320 to provide a total of four fourth switches 540. In addition, the fourth switches 540 may be disposed such that the pressed button portion faces the inner circumferential surface of the ring portion 430 or is in contact with the inner circumferential surface, and the fourth switches 540 are coupled to and fixed to the second support portion 320. Can be. In addition, as an example, the fourth switch 540 may be arranged at an angle position rotated by 45 degrees in the x-axis direction and the y-axis direction, and thus the user may teach the handle 410 in an oblique direction in the x-axis direction or the y-axis direction. When the operation of pushing) is pressed, the inner circumferential surface of the ring portion 430 of the teaching handle 410 presses a fourth switch 540 to operate the switch. Accordingly, the manipulation of the teaching handle 410 can be detected. As described above, the robot may be controlled to move in a desired direction by receiving the operation signals of the switches operated by being pressed among the fourth switches 540.

In addition, the push button switch 500 is disposed between the upper structure 100 and the teaching handle 410 and between the lower structure 200 and the teaching handle 410, spaced apart along the circumferential direction The third switch 530 may be further included.
