Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention automatically and continuously evaluates a large number of inspection items in parallel to determine pass/fail.
It relates to automatic electrical property inspection equipment for wire and wheel parts that sorts out defective products.

0002

[Prior Art] Conventionally, this type of work was performed manually, and each test item was performed manually by a highly skilled person, making it difficult to improve workability, speed, and measurement accuracy. Furthermore, human errors occurred frequently, making it difficult to deal with them in a planned production process. In addition, because there are many inspection items for wire and wheel parts and many terminals, inspection automation involves repeating single-item continuous measurement devices, or systems that switch and measure multiple items using one measurement terminal. In the former case, there is a problem in that it takes time to determine whether a part is acceptable because the measurement of each item is completed repeatedly for each lot, and it is only known at the time of the final measurement of the characteristic items. Furthermore, when evaluating the characteristics of multiple items using one measurement terminal, it takes a long time to evaluate each item because there are many items, and there is a problem that it is difficult to increase the processing capacity.

0003

[Problems to be Solved by the Invention] The present invention solves the above-mentioned problems and continuously and automatically evaluates the electrical characteristics of multiple items of wire and wheel parts such as transformers and coils. Measurement terminals corresponding to each individual object are prepared in a straight line and can be evaluated continuously.Evaluation of each solid can be completed before the measurement of the entire lot is completed, and evaluation can be performed continuously using a large number of measurement terminals for each characteristic. Therefore, the present invention aims to provide a wire and wheel component electrical characteristic testing device that can significantly shorten evaluation time and save manpower.

0004

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention is an inspection device that continuously and automatically evaluates and determines a plurality of characteristics of wire parts to be inspected in parallel. It is supervised by a computer that individually controls the work of the measurement system that measures the characteristics of parts, organizes the results, and sends signals corresponding to the necessary processing to the measurement and evaluation system, storage system, transportation, and control system. The contact pin probes installed in a straight line for measuring each characteristic are independent for each characteristic item, and the rod feeding mechanism installed on the side feeds the wire parts to be inspected one after another, and each characteristic item is measured in parallel. This is an inspection device that can determine the quality of each part and classify it immediately after the final item is completed.

That is, in a device that continuously and automatically tests the characteristics of coil parts such as transformers and coils, there is a test article delivery unit that stores and supplies the coil parts to be inspected (hereinafter referred to as the test article), and an inspection sorting unit. It basically consists of a measurement table for receiving and storing inspected items after inspection, and a non-defective storage unit for receiving and storing inspected items.It is also located between each unit and device, and is used for pick-and-place and transfer of inspected items to the next equipment. It is equipped with a buffer conveyor for adjustment, controls multiple measuring instruments and their terminals that evaluate the characteristics of multiple predetermined inspection items, and controls these measurement systems, and also organizes and displays the measurement results and determines pass/fail. A computer that instructs the sorting machine is built in, and contact pin probes corresponding to a plurality of designated test items are installed in a straight line on the measuring table, each independently for each test item, and on the side of the contact pin probe. is a multi-item parallel continuous inspection type that has a rod feeding mechanism that brings the test item sent out from the test item delivery unit into contact with the contact pin probe for each inspection item, and then moves it to the contact pin probe for the next inspection item. This is an electrical characteristic testing device for wire and wheel components characterized by its configuration.

[0006]

[Operation] A measuring table with contact pin probes that correspond to multiple electrical property items required for inspection of wire and wheel parts arranged in a straight line, and a rod feeding mechanism that attaches and moves the test piece to each contact pin probe. are set up and measured using each measurement system, parallel measurement processing is performed for each measurement item, the measurement results of each item are judged comprehensively and pass/fail is determined, and the items to be tested are brought in and out for measurement. By controlling the sorting by a computer together with the control of the measurement system mentioned above, multiple inspection items of wire and wheel parts are inspected and sorted in a continuous and automatic parallel manner, and the inspected items are supplied and stored, allowing inspection to be carried out in a short time. Moreover, even in the middle of a large lot, it is possible to classify good products from those that have been inspected.
