Tester automatic all-purpose and measurement method it uses}

The present invention relates to a general-purpose automatic tester and a measuring method using the same, and more particularly, the functional test and durability, aging test of automotive electronics, mobile phones, copier controllers, mice, hinges, hands-free, carbon resistance PCB, Bluetooth, etc. In doing so, the program and system of the automatic tester are integrated to make it easy and quick to access even those who do not have professional knowledge, and the system can be configured by adding only the cards corresponding to the necessary test items. As a result, the quality and reliability of the products have been greatly improved, allowing consumers to plant good images.

As is well known, an inspection machine refers to a machine that inspects an object by using any device or system when the object cannot be properly inspected by the human eye.

For example, the inspection of 100 µm or less by using a microscope is an example. Furthermore, the system automatically inspects and judges automatically by using a PC and an electronic system, and the robot is applied to the unmanned automatic judgment and automatic. The processing unit is commonly referred to as the inspector.

Core technologies require quite a lot of experience and comprehensive technology such as lighting (optical) technology, lens, camera, image capture, PC technology, program design technology, image processing technology, mechanical technology, electrical & electronic technology, robot technology, and semiconductor technology. It is a machine.

However, the above-described conventional inspection machine has been a lot of problems, such as to avoid the use.

In other words, the conventional inspection machine is now required to secure high-quality manpower, because most of them rely on custom-made, both domestic and foreign, and the production period is long. It's expensive. The reality is that many problems are scattered, including lack of reliability. However, it is burdensome to build such a system by securing high-quality manpower from small and medium-sized companies, and even if the engineer who is in charge of the company leaves the company, it is often rusted as an unusable equipment.

In addition, there are many systems that measure and test single items such as individual DAQ cards on the market, but if you use them, you have to write a separate program, and even the hardware configuration must be tailored to the test object. It is necessary. For this reason, it is difficult for small and medium-sized companies to introduce automatic testers, and it is difficult to secure high-quality manpower.

When the automatic tester is manufactured using the DAQ card, the actual measuring card costs only several million won, and the design program cost, etc., adds up to tens of thousands of won. For this reason, these systems are mainly used by large corporations, but most of them are unable to replace them at the present time when labor costs increase.

In addition, the prior art dedicated system has a non-flexible problem by fixedly combining a number of functions only by dedicated operation, so if the user performs operations such as adding or improving the function of the dedicated system that the user currently possesses, It takes a lot of effort and time to fix the fixed part.

On the other hand, domestic companies are launching equipment that includes ICT functions and functional tests, but this too is not easy without borrowing the skills of advanced engineers, and it is expensive to reach tens of millions of won.

The present invention has been made to solve the problems of the prior art as described above, and the first object of the present invention is to make it easy for the user to easily access by measuring all measurement cards rather than a dedicated tester for a specific product.

The fifth purpose is to supply the operating program free of charge and select only the necessary cards in the system. In order to reduce the cost and to be able to manage the product itself after the production, the 6th objective is to make it possible to attach and detach the functions fixed in the dedicated system. The purpose of the seventh objective is to provide a general-purpose automatic inspector and a measuring method using the same to greatly improve the quality and reliability of the product, thereby allowing consumers to plant a good image.

In order to achieve this purpose, the present invention is provided with a tester to interface data with LPT or USB of the PC 1, to control the respective cards, to store the values measured on each card in the hard disk of the PC and to load the data of the required date It is possible to change the setting according to the characteristics and characteristics of the product to be inspected, and the controller is equipped to manage the production history and upgrade according to the addition of the model.
