Abstract

PURPOSE:To enable saving works for making an inspection pattern and inputting prior to the inspection by taking in the response from a normal electrical equipment prior to the inspection and automatically inputting to an inspection pattern memory. CONSTITUTION:If an output pattern signal necessary for an inspection is sent from an output part 3 to a normal electrical equipment 2, the response from this electrical equipment 2 is taken in by way of a switching part 7, a necessary inspection pattern is automatically made and input to an inspection pattern memory 4. Then, the switching part 7 is set to the judging part 5 side and on the other hand, another switching part 8 is set to the judging part 5 side to inspect an inspected goods 2. In other words, output pattern signal necessary for the inspection is sent from the output part 3 to the goods under inspection 2 at a predetermined timing and, by comparing the response from the goods under inspection 2 with the inspection pattern stored in the memory 4, an inspection whether the goods 2 is good or not is performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric component inspection apparatus for inspecting an electric component such as a printed wiring board or an electronic component mounting unit to determine whether it is good or bad.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram showing the structure of a conventional inspection apparatus of this type. In the figure, 1 is an inspection device, 2 is an inspected product (electrical component), 3 is an output unit for outputting an output of a predetermined pattern from the inspection device 1 at a predetermined timing, and 4 is provided in the inspection device 1. An inspection pattern storage unit that stores inspection pattern data. Reference numeral 5 is a judgment unit for comparing the response from the inspected product 2 with the inspection pattern, and 6 is a control unit for receiving the timing data from the output unit 3 and controlling the output unit 3, the inspection pattern storage unit 4, the judgment unit 5, and the like. Is.

The inspection device 1 and the inspection object 2 are connected to inspect the inspection object 2. In advance, the inspector operates the normal electrical component 2 for the output pattern from the output unit 3 at a predetermined timing.
The response from is predicted or measured, a necessary inspection pattern is created from the result, and stored in the inspection pattern storage unit 4. In this state, first, when a signal having a predetermined output pattern is sent from the output section 3 of the inspection device 1 to the inspected product 2 at a predetermined timing necessary for the inspection, a response from the inspected product 2 is sent to the inspection device 1. The quality of the inspected product 2 is judged by taking in the data and comparing it with the inspection pattern stored in the inspection pattern storage unit 4 by the determination unit 5.

[0004]

However, according to the above-mentioned conventional structure, the inspector predicts or measures the response of the normal inspected product to the predetermined timing data in advance, and the inspection required for the inspection is performed based on the result. You have to create a pattern, which is a lot of work. Further, it takes time and labor for the inspector to input the created inspection pattern into the inspection pattern storage unit 4, and at that time, an input error may occur.

The present invention has been made to solve the above problems, and saves labor for creating and inputting an inspection pattern prior to performing inspection, and eliminates input errors. An object of the present invention is to provide an inspection device for electrical components that can be used.

[0006]

In order to achieve the above object, the present invention sends an output pattern required for inspection from an output section to an inspected product at a predetermined timing, and stores a response from the inspected product and an inspection pattern storage. In the inspection equipment for electrical equipment that compares the inspection pattern stored in the inspection section with the determination section to inspect the inspected product, the inspection pattern is automatically the response from the normal electrical equipment as the inspection pattern prior to the inspection. The configuration is such that input means for inputting to the storage unit is provided.

[0007]

In the above structure, the inspection device has the learning function of making the response from the normal electric component into the inspection pattern. Therefore, the predetermined output pattern is sent from the output section to the normal electric component prior to the inspection. By doing so, the required inspection pattern is automatically stored in the inspection pattern storage unit, which saves the trouble of creating the inspection pattern and eliminates the occurrence of input errors.

[0008]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a block configuration diagram showing an inspection apparatus for an electric component according to an embodiment of the present invention. The same parts as those in the conventional example shown in FIG.

In FIG. 1, a response from a normal electrical component 2 is fetched between the inspected product 2 and the inspection pattern storage unit 4 and the inspection pattern is automatically stored as a required inspection pattern. A switching unit 7 is provided as an input means for allowing the unit 4 to switchably input and learn. A switching unit 8 is provided between the inspection pattern storage unit 4 and the determination unit 5 and is opened when a response from the normal electrical component 2 is input to the inspection pattern storage unit 4.

The operation of the above structure will be described below. First, prior to the inspection, the switching unit 7 is set on the inspection pattern storage unit 4 side, and the other switching unit 8 is set on the open side. First, if a signal of an output pattern required for inspection is sent from the output unit 3 to the normal electrical component 2, the response from this normal electrical component 2 is taken in via the switching unit 7, and the required inspection pattern is obtained. It is automatically created and input to the inspection pattern storage unit 4. That is, the normal electrical component 2
The response from is input to the inspection pattern storage unit 4 as an inspection pattern necessary for the inspection and learned.
In this case, the creation of the inspection pattern prior to the inspection and the automation of its input can be achieved to reduce the labor and eliminate the risk of an input error.

After that, the switching unit 7 is set on the determination unit 5 side, while the other switching unit 8 is also set on the determination unit 5 side to inspect the article 2 to be inspected. That is, a signal of an output pattern required for the inspection is sent from the output unit 3 to the inspected product 2 at a predetermined timing, and the response from the inspected product 2 is stored in the inspection pattern storage unit 4 in advance. As a result, the quality of the inspected product 2 is inspected.

[0012]

As described above, according to the present invention, a response from a normal electrical component is fetched prior to the inspection and is automatically input to the inspection pattern storage unit as the inspection pattern required for the inspection. Therefore, the labor required for the inspection is reduced, and the risk of an input error is eliminated.
