1. Overview

This system is an automatic sorting system for AC capacitors. When in use, as long as the tested capacitor is inserted into the fixture of the system, the system can automatically test and sort different items of the tested parts according to different test requirements, and collect the test results of each item by classification (qualified products and unqualified products).

2. System Overview

The system is divided into "test discrimination" and "transmission sorting" two parts. The test fixture is installed on the test disc of the transmission sorting part. The operator will send the tested capacitor into the fixture of the system. The system will automatically transmit it to the test head of each test part for automatic test. According to the measured parameters, the qualified products or unqualified products of each grade will be classified and collected separately. (Centralized sorting of nonconforming products of this machine). The system can test and judge the following items of capacitors according to the process:

ACTV1→ACTV2→IR→CAP.DNG1→ΔC1

Setting: in the test range of two-digit arbitrary setting

Test accuracy: 102MΩ is ± 10%,103MΩ is ± 10%,104MΩ is ± 20%.

Unqualified detection: the capacitor whose measured value is lower than the set value is automatically rejected after discharging three stations.
