Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an industrial robot,
The present invention relates to a hand-held operation device for operating other industrial automatic machines.

[0002]

2. Description of the Related Art FIG. 4 is a front view showing a conventional hand-held operation device for operating a machine (not shown) while holding it with one hand. As shown in FIG. 4, the conventional hand-held operation device includes a housing 1 that is held by one hand from both sides 1 b and 1 c,
It has an operation unit 3 provided on the upper surface 1a of the housing 1 and an enable switch 20 provided on the side surface 1c.

[0003] The enable switch 20 does not permit the machine to operate when it is not pressed with a finger, but allows the machine to operate when it is pushed down to a finger (operable state), and when it is fully pressed. Do not allow the machine to operate (enabled).

[0004]

However, if the user attempts to operate the operation unit 3 while holding the housing 1 with one hand, there is a problem that the enable switch 20 is inadvertently pushed completely and erroneously operated. In this case, the machine is stopped carelessly.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to obtain a hand-held operation device for preventing a switch provided on a side from being erroneously operated.

[0006]

Means for Solving the Problems According to a first aspect of the present invention, there is provided a housing which is sandwiched by one hand from both sides, an operation unit provided on an upper surface of the housing, and a housing provided on the side surface. ,
An actuator section that retreats by receiving a pressing force from the one hand, and rotates around a fulcrum when pressed and abutted on the actuator section, but pushes back the actuator section with a predetermined urging force, and is pressed by the actuator section. The position of contact with the actuator unit gradually approaches the fulcrum as the position of the actuator unit increases, and an electric state switches according to the rotation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A hand-held operation device according to an embodiment of the present invention will be described. The appearance of the hand-held operation device according to the first embodiment of the present invention is the same as the conventional hand-held operation device shown in FIG. That is, FIG. 4 is a front view showing a hand-held operation device for operating a machine (not shown) while holding it with one hand. The hand-held operation device according to the embodiment has a single-handed
b, 1c, and an operation unit 3 provided on an upper surface 1a of the housing 1. The operation unit 3 includes, for example, a plurality of tact switches arranged in a matrix.

FIGS. 1 to 3 are conceptual views showing the internal structure of a hand-held operation device according to an embodiment of the present invention. In the hand-held operation device according to the embodiment of the present invention, the enable switch 20 shown in FIG. 4 is replaced with the enable switch 2 shown in FIGS.

The enable switch 2 is a rotating cover 2
a, a rod 2b, and a switch 2c. One end of the rotating cover 2 a is rotatably attached to the housing 1. The rod 2b is inserted into a through hole 1d provided in the side surface 1c of the housing 1, one end of the rod 2b contacts the rotating cover 2a, and can freely move through the through hole 1d in the forward and backward directions X1, X2.

The switch 2c has the same structure as the conventional enable switch 20. The switch 2c is a rotary button 2.
ca. One end of the rotation button 2ca is a rod 2b.
Abuts against the other end of the body, and is pushed by the rod 2b so that the center body 2 at the other end is
Rotate around cb. The switch 2c is a rotary button 2c
The electrical state (on, off) switches according to the rotation of a.

The rotating cover 2a and the rod 2b constitute an actuator section.

Next, the operation will be described. When no pressing force is applied to the rotating cover 2a from outside (FIG. 1),
The rod 2b is advanced in the forward direction X1 by the urging force of the switch 2c in the forward direction X1 from the rotary button 2ca. Is in contact with In this state, since the switch 2c is off, the machine is not permitted to operate, and the machine stops operating.

Next, the operator holds the housing 1 with one hand on both sides 1
b, 1c, and presses the rotating cover 2a with a finger. The rod 2b is pushed by the rotating cover 2a and retreats in the retreating direction X2, and the one end of the rotating button 2ca is pushed by the edge 2ba of the rod 2b and turns around the center body 2cb on the other end in the retreating direction X2. Move. When the rotation button 2ca is rotated, the edge 2bb of the rod 2b close to the center body 2cb abuts on the rotation button 2ca instead of the edge 2ba. As described above, when the position (edge 2ba or edge 2bb) where the rod 2b and the rotation button 2ca are in contact with each other approaches the center body 2cb (fulcrum), the rotation button 2ca is drastically rotated by the leverage principle. It stops when the edge 2bb comes into contact with the rotation button 2ca, and the switch 2c is turned on (FIG. 2). Since the switch 2c is turned on, the machine is allowed to operate, and the machine can operate.

Next, the operator pushes the rotating cover 2a dramatically and strongly with a finger. Then, the rod 2b is pushed by the rotating cover 2a and retreats in the retreating direction X2, and one end of the rotating button 2ca is pushed by the edge 2bb of the rod 2b and the central body 2c
It further rotates in the retreating direction X2 about b (FIG. 3). As a result, the switch 2c switches the electrical state from on to off, does not allow the machine to operate, and stops the operation.

As described above, even if the user tries to operate the operation unit 3 with the thumb or the like while holding the housing 1 with one hand, the rotation button 2ca is difficult to turn drastically. 2 can be prevented from being erroneously operated by being completely pressed. This can reduce the burden on the operator.

The rod 2b is connected to the edges 2ba, 2bb.
By replacing the rod with another rod having a different distance therebetween, it is possible to adjust the difficulty of the rotation of the rotation button 2ca.

The rotation button 2ca is formed by using a spring or the like.
The configuration is simpler and the size of the enable switch 2 can be reduced as compared with the configuration in which it is hard to rotate.

[0018]

According to the first aspect of the present invention, even if the user tries to operate the operation unit while holding the housing with one hand, the switch is difficult to turn dramatically, and the switch is erroneously operated. Can be prevented.
