Abstract

PURPOSE:To easily inspect various kinds of components with high reliability by holding a component to be inspected at a constant attitude and setting a turntable so that its one surface contacts the conduction part of the component to be inspected and the other surface abuts on an inspection position. CONSTITUTION:The turntable 7 is equipped with a component normalizing part 8 which holds the attitude of the component 6 to be inspected constant and an abutting element 9 which contacts the conduction part of the component 6 to be inspected on one surface and abuts on the contact 10 on the other surface at the inspection position. Then when the component 6 to be inspected is carried to the inspection position and the contact 10 is elevated, the contact 10 does not abut directly on the conduction part of the component 6 to be inspected, but abuts on the reverse surface of the abutting element 9 to determine inspection conditions. Consequently, even when a component 6 of different size is inspected, the shape of the abutting element 9 is unchanged, so the contact 10 need not be shifted in installation position.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a component inspection device for inspecting the performance, acceptability, defect, etc. of small electronic components.

BACKGROUND OF THE INVENTION In recent years, technological advances in electronic components have been remarkable, with the trend toward smaller size and higher performance of components, and component inspection equipment that automatically inspects these components with high reliability is playing an important role. In this component inspection apparatus, the method of placing the component to be inspected on a turntable and transporting it to each inspection position is advantageous in terms of area efficiency in the case of multiple inspections, shortening of transportation time, and the like.

An example of the above-mentioned component inspection apparatus will be described below with reference to the drawings.

3 to 5 show a conventional component inspection device. In Fig. 3, 1 is the part to be inspected, 2 is the part to be inspected 1
3 is an indexing device that provides intermittent rotational drive to the turntable 2.

4 is a contact that comes into contact with the inspected part 1 at each inspection position and provides inspection conditions; and 6 is a cylinder that moves the contact 4 up and down. As shown in FIG. 4, the turntable 2 is provided with a hole through which the contact 4 passes through the conductive portion of the component 1 to be inspected.

The operation of the component inspection apparatus configured as described above will be explained. The component to be inspected 1 placed on the turntable 2 at the component supply position is transported to each inspection position by the indexing device 3 being driven. At each inspection position, the contact 4 is raised by the cylinder 5 and comes into contact with the conductive portion of the component 1 to be inspected, thereby providing inspection conditions. When the inspection is completed, the cylinder 6 lowers the contact 4 and transports it to the next position. After all inspections are completed,
The part to be inspected 1 is taken out from the turntable 2 at the part taking out position.

Problems to be Solved by the Invention However, with the above configuration, since the contacts come into direct contact with the lower surface of the part to be tested, there is a risk that the posture of the part to be tested may change, and the test conditions such as contact resistance will not be constant. The problem was that reliability could not be guaranteed.

In addition, as shown in FIG. 6, when inspecting a component 1b that is different in size from the component 1a shown in FIG. The problem was that it was not easy.

In view of the above-mentioned problems, the present invention provides a parts inspection device that guarantees high reliability and can easily inspect a wide variety of parts.

Means for Solving the Problems In order to solve all the above problems, the parts inspection device of the present invention has the following features:
The turntable is equipped with a component regulating part that maintains the posture of the component to be inspected in one position, and a contact element that contacts the conductive part of the component to be inspected on one side and contacts the contact on the other side at the inspection position. It is.

Function: With the above-described configuration, the present invention eliminates the risk of changing the posture of the inspected component because the contact does not come into contact with the inspected component. In addition, even when inspecting a wide variety of parts, by keeping the shape of the contact contact surface of the contact element constant, there is no need to change the installation position of the contact, and the inspection of a wide variety of parts can be easily performed.

Embodiment Hereinafter, a component inspection apparatus according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a partially enlarged view of a turntable of a component inspection device according to an embodiment of the present invention. In FIG. 1, 6 is a part to be inspected, 7 is a turntable main body, and 8 is a component regulating part which is attached to the turntable main body 71C and keeps the posture of the part to be inspected 6 constant.

Reference numeral 9 is a contact element made of a highly conductive material that is embedded in the turntable main body 7 and contacts the conductive part of the component to be inspected 6 on the upper surface; 1o is in contact with the contact element 9 at the inspection position, and the contact element 1o Note that the overall configuration of the device is the same as the conventional component inspection device shown in FIG.

The operation of the component inspection apparatus configured as described above will be described below. The basic operation is the same as that of conventional component inspection equipment, but when the component 6 to be inspected is brought to the inspection position and the contact 10 is raised, the contact 1o comes into direct contact with the conductive part of the component 6 to be inspected. Instead, the test condition is applied by contacting the lower surface of the contact element 9.

Accordingly, as shown in FIG. 2, even when inspecting a component to be inspected 6b that is different in size from the component to be inspected 6a in FIG. There is no need to change the installation location.

Effects of the Invention As described above, the present invention provides a component inspection device that includes a turntable on which a component to be inspected is placed and rotates intermittently to an inspection position, and a contact that achieves inspection conditions for the component to be inspected at the inspection position. The turntable has a regulating part that keeps the posture of the part to be inspected constant, and a contact element that contacts the conductive part of the part to be inspected on one side and a contact on the other side at the inspection position. In addition, the posture of the part to be inspected can be kept stable and constant, making it possible to perform highly reliable inspections, and it is also possible to easily inspect a wide variety of parts without changing the installation position of the contacts.

FIG. 4 and FIG. 6 are partially enlarged sectional views of the conventional component inspection device. 7
