Abstract

PROBLEM TO BE SOLVED: To miniaturize a parts transfer equipment, and improve area productivity in a production line. SOLUTION: A motor 11 can swung centering around a shaft 12. By the rotation of the motor 11, the screw part of a ball screw 15 is rotated, and the nut 14 of the ball screw 15 is moved. One end of a lever 16 is connected to the nut 14, and the lever 16 performs its rotational movement centering around a pin 18(a), therefore, the other end of the lever 16 performs its circular movement, and a tool 19 attached to a sliding part 17 is actuated along the sliding part 17 through a shaft 18(b).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to transfer of parts.

[0002]

2. Description of the Related Art A conventional component transfer device will be described below.

FIG. 4 and FIG. 5 show a conventional component transfer device. In FIG. 4, 41 is a motor, 42 is a ball screw, 43 is a slide guide, and 44 is a main body frame.

The motor 41 and the ball screw 42 are directly connected, and the nut portion of the ball screw 42 is attached to the slide guide 43.
Attached to. All of these are attached to the main body frame 44 to form one unit.

Therefore, by rotating the motor 41, the ball screw 42 rotates and the nut portion moves along the slide guide 43.

By combining the uniaxial units at a right angle, a biaxial component transfer device is formed.

[0007]

However, the above structure has the following problems.

Since the uniaxial drive device is orthogonally combined for two axes, the size in the width direction needs to be increased by two axes and the width of the tool portion.

Further, since the length is increased in the vertical direction as well, the space occupied by the component transfer device becomes much larger than that of the parts to be transferred.

An object of the present invention is to solve the above problems and to provide a small-sized component transfer device with an easy structure.

[0011]

In order to achieve this object, the component transfer device has the following configuration.

The motor is arranged so as to be able to oscillate with respect to the base portion about the shaft. When the motor rotates, the screw portion of the ball screw rotates and the nut portion of the ball screw moves. One end of the lever is connected to the nut, and the lever rotates about the pin, so the other end of the lever moves in an arc, and the tool part attached to the slide part moves along the slide part via the shaft. . Therefore, the tool unit is configured to move up and down by the forward and reverse rotation of the motor.

With this configuration, it is possible to reduce the size of the component transfer device and improve the area productivity in the production line.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) An embodiment of the invention described in claims 1 and 2 will be described.

In FIG. 1, 11 is a motor, 12 is a shaft, 15 is a ball screw, 16 is a lever, and 17 is a slide portion.

The motor 11 can swing about the shaft 12 with respect to the base portion 13. Motor 11
Is rotated, the screw portion of the ball screw 15 is rotated, and the nut portion 14 of the ball screw 15 is moved. Since one end of the lever 16 is connected to the nut 14, and the lever 16 makes a rotational movement about the pin 18 (a), the other end of the lever 16 makes an arc movement and slides via the shaft 18 (b). The tool unit 19 attached to 17 operates along the slide unit 17. Therefore, the tool portion 19 moves up and down by the motor 11 rotating in the forward and reverse directions. By attaching this to a uniaxial operation device, a biaxial component transfer device can be obtained.

(Embodiment 2) An embodiment of the invention described in claim 3 will be described.

In FIG. 2, reference numeral 21 denotes a slide guide, which is coupled to the nut portion 14 of the ball screw. When the motor 11 rotates, the nut 14 of the ball screw operates along the slide guide 21.

(Embodiment 3) An embodiment of the invention described in claim 4 will be described.

In FIG. 3, 31 is a cylinder,
As the cylinder 31 expands and contracts, the lever 16 operates.

[0022]

As described above, according to the present invention, the output shaft of the motor is directly connected to the ball screw, and one end of the lever having the rotation center on the base portion is attached to the nut portion of the ball screw. By attaching the slider to the slide portion, the operation direction can be changed and a small component transfer device can be obtained.
