Description

TECHNICAL FIELD [0001] The present invention relates to an automation system for compatibility test of wireless power transmission / reception products and a dedicated jig set for the automation system.

The present application relates to a system for automating compatibility testing of wireless power transmission and reception products and a dedicated set of jigs for the same.

The wireless power transmission products are divided into conformity test and interoperability test according to the international standard.

The conformity test described above is a test to check whether the product to be inspected (eg smart phone, smart phone wireless charger) is designed to conform to the international standard (Qi, AirFuel), whether it satisfies the international standard performance specification .

On the other hand, the interoperability test is conducted with the products to be inspected (eg, smart phone, smartphone wireless charger) and standard certified products (eg, smart phone, smartphone wireless charger) To check if it is compatible.

There is only one product to be tested, and one should be tested for interoperability with 200 other company standard certified products. In other words, one test product and 200 standardized products of 200 companies should be tested 200 times. In reality, there are about 200 international standards (Qi, AirFuel) certified products around the world, and it is troublesome to test them all 200 times.

In addition, since the number of international standard certification products is increasing every year, there will be several hundreds of international standard certification products within a few years, so that the number of repetitive tests by workers is increased to several hundreds or more, Reproducibility, accuracy, and the like.

In international standards (Qi, AirFuel) interoperability test, in the past, the operator placed the product to be tested on the test table, brought the standard certified product one by one, and performed the interoperability test manually.

This interoperability test method has a problem that the inspection worker repeatedly performs the test / inspection process 200 times.

Also, it is difficult to perform a proper performance test according to the fatigue of the inspection worker, difficulty in ensuring the reproducibility of the inspection, and low inspection accuracy.

In addition, although the center point between the center of the transmission electric power transmission coil to be inspected and the center of the water electric power reception coil, which is a standard certified product, should be exactly aligned, the operator has difficulty in correctly placing the power reception coil at the center of the transmission coil. This is because it is difficult to precisely check the position of the transmission coil in the transmission, because the center of the coil of the sub-transmission is covered by the top water electricity when the water electricity is placed on the transmission.

In the case of multi-coil transmission with several transmission coils in the transmission line, it is necessary to move the transmission coil center point of the multi-coil transmission line to the side of a certain range (for example, 5 mm) It is difficult to precisely check the position of the transmission coil of the multi-coil transmission electricity because the lower multi-coil transmission electricity is covered by the upper water electricity when it is placed on the coil transmission electricity, It is difficult to observe with the naked eye.

In addition, the wireless power transmission interoperability test is to test whether there is interchangeability between different power transmission and transmission periods, and the worker should be next to the product to be inspected to visually confirm interchangeability between products. At this time, the power supply and the power transmission are in operation, and since the power is being transmitted wirelessly, the worker's human body can be influenced by electromagnetic waves.
