Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating mechanism for changing the direction of an electronic component as an object to be measured in an automatic carrier for an electronic measuring instrument for measuring the electrical characteristics of the electronic component. .

[0002]

2. Description of the Related Art When measuring the electrical characteristics of electronic parts,
The measurement is performed using the connection terminals such as input, output, and ground of the electronic component that is the object to be measured as measurement terminals. However, for example, some frequency filters have a characteristic that they can be used in an electronic circuit by replacing the input with the output and the output with the input side. However, the measurement results of the characteristics in the case of the two directions are generally not the same value and generally have some differences. Therefore, on the manufacturer side, which terminal should be used by the user as an input terminal or an output terminal when measuring the characteristics for shipping the product should satisfy the standard value desired by the user. To judge. Finally, when the product is used by the user, the manufacturer displays which is the most suitable input terminal and the most suitable output terminal, and the product is shipped to the user (see FIG. 2).

As described above, the same connecting terminal provided on the electronic component is used as a measuring terminal. At that time, it is necessary to use an object to be measured to compare and measure the electrical characteristics as an input side or an output side. It is necessary to change the orientation of a certain electronic component to change it. The reason is that the object to be measured is carried in or out at a predetermined position by an automatic carrier called a handler, but the measuring unit on the electronic measuring instrument side is fixed, and the measuring prober operating there is also at a predetermined position. It is usually set in the direction. Therefore, in order to change the orientations of the input side and the output side and measure the characteristics, the direction of the electronic component that is the object to be measured is changed.

Therefore, in the prior art, a power for changing the direction, such as a stepping motor or a servomotor, is provided separately from the power for automatic conveyance. Therefore, (1) the mechanism is complicated by the amount of the separate provision. (2) A lot of man-hours are required for assembly and adjustment. (3) There is a problem that the cost is increased as a result.

[0005]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to measure an electronic component which is an object to be measured in an automatic carrier for an electronic measuring instrument for measuring the electrical characteristics of the electronic component. With the rotating mechanism used to change the direction, it is possible to easily change the measuring direction of electronic parts without additionally providing power such as a stepping motor or servo motor, which is separate from the power for automatic conveyance. That is.

[0006]

An automatic carrier in an electronic measuring system carries in electronic parts as an object to be measured one after another to a predetermined position based on a predetermined sequence, or It is something that is carried out.

According to the present invention, a cam portion and a rotary plate are provided on a slide table which moves on a slide rail in a predetermined direction by a power source which the automatic carrier already has, and a cutout portion is provided on the rotary plate. Provided. That is, when the slide base starts moving,
The rotation control pin, which is a cam follower, slides following the shape of the cam portion to give a component force to the cutout portion of the rotation plate, so that the rotation plate starts circular motion. When the rotation control pin passes through the cam portion, the circular motion stops, and at the same time, the electronic component, which is the object to be measured and is placed on the rotating plate, is configured to change its direction in a predetermined direction.

[0008]

According to the present invention, the power for horizontal movement when the slide base moves in a predetermined direction on the slide rail is provided by the existing power source that is indispensable for the basic transfer operation as the automatic transfer machine. By using the mechanism to generate the rotational force, it is not necessary to provide a dedicated power source only for changing the direction of the electronic component that is the object to be measured.

FIG. 1 is a conceptual diagram showing one embodiment according to the present invention. In (a) to (d), the rotation state of the rotary plate is shown in a plan view and a side view for each process. (1) In an electronic measurement system, an electronic component, which is an object to be measured, is carried in and out of a predetermined position according to a predetermined sequence by an automatic carrier usually called a handler. As shown in FIG. 1, in the rotating mechanism of the present invention, a predetermined moving direction 1 is set on the slide rail 2 of the X-axis 13 by the power already possessed by the automatic carrier.
A cam 5 and a rotary plate 4 are provided on the sliding base 1 that moves to 1, and a cutout portion 8 is provided on the rotary plate 4.

(2) When the slide base 1 starts to move, the rotation control pin 3, which is a cam follower, slides in the sliding direction 12 on the Y-axis 14 following the shape of the cam 5, and rotates the rotary plate. Since it gives a component force to press the notch 8 of 4,
The rotating plate 4 starts circular movement. (3) Next, when the rotation control pin 3 passes through the cam 5, the circular motion stops, and at the same time, the electronic component 7, which is the object to be measured and is placed on the rotating plate 4, is directed in a predetermined direction. Will be converted. In the present embodiment, the position shown in FIG.
(B) → (C) elapses, and at the position shown in Figure 1- (D), 18
This indicates that the direction of the electronic component 7 is changed by 0 °.

(4) FIG. 2 is a plan view of the surface of the electronic component 7 which is the object to be measured having the connection terminals, in which the input terminal 15, the output terminal 16 and the GND terminal 17 are arranged. Indicates that. (Output ←) or (← Input) indicates that the role of the terminal changes when the direction is changed.

(5) Further, the shape of the rotary plate 4 need not be circular only. (6) Further, even if the shape of the cam 5 of the present embodiment is the same, the notch 8 is formed as the notch 6 having an arbitrary angle, so that the direction change angle can be adjusted to an arbitrary angle.

(7) Further, the rotation control pin 3 has the rotary plate 4
By adding a mechanism for controlling the cutout portion 8 so as not to cover the cutout portion 8, it is possible to deal with the case where the direction change of the electronic component 7, which is the object to be measured, is unnecessary.

(8) The rotating mechanism according to the present invention can be applied not only as a rotating mechanism of an automatic carrier which is a handler in an electronic measuring system, but also as a rotating mechanism for other purposes.

[0015]

Since the present invention is configured as described above, it has the following effects. (1) Since the rotating mechanism as in the present invention does not require a separate dedicated power for changing the direction of the electronic component that is the object to be measured, the cost is reduced by the amount that the mechanism is unnecessary. Down was achieved. (2) Therefore, since the mechanism does not become complicated by that much, the time required for assembly and adjustment can be shortened, and further increase in cost can be prevented. (3) In addition, the measurement result of the characteristic is different when the measurement direction is different, and it is inexpensive even for the object to be measured that needs to be judged and selected based on the result. It became possible to cope easily by the structure of the mechanism.
