Supercapacitor Testing And Sorting Machine

Supercapacitor test separator 1 Applicable range: suitable for diameter 4 22mm, aluminum shell length 8 ~ 40mm, test voltage from 0V ~ 5VDC. 2ã?? Test item: ESR (1kHz) fixed current pulse charging 60s charging voltage. Three. Test process: the farad capacitor is fed through the vibrating material tray, and then transferred to the test conveying chain through the flat feeding and the hand over feeding of the manipulator. First, the guide pin is shaped; then, the polarity is tested, and the stepping motor is automatically reversed. After the second foot trimming, the products whose voltage at the test capacitor end is greater than 20mV are put into the retest material box, and the equivalent series resistance ESR (frequency 1kHz, apply 1mA or 10mA current, check Measure the voltage at the end of the capacitor, record the ESR grading range (high ESR, low ESR) of the measured capacitance with the internal resistance test instrument, directly discharge the ESR defect, then detect the open circuit and short circuit, enter the open circuit and short circuit material box, set the constant current charging current I of the capacitor, and pulse the farad capacitor on the test chain for 60s 0.1s, Carry out the voltage test at the end of the capacitor; unqualified voltage products enter into the poor voltage material box; Classification of qualified products (1) High voltage & high ESR (2) High voltage & low ESR (3) Low voltage & high ESR (4) Low voltage & low ESR, unqualified gear is divided into two gears, (5) Open circuit (6) Short circuit, 6 gears in total, then enter the load discharge and short circuit discharge section, six kinds of which are put into the corresponding material box respectively. 4 Performance 1. Single phase AC220V power supply of vibrating plate feeding system, 50 / 60Hz 1. Open circuit short circuit detection power supply DC 0v-5v 10A 1. 60s charging voltage detection single channel constant current setting range: 0.01a-5a can be set, accuracy < 1%; charging time: 60s ± 0.1s; display setting value; voltage test accuracy: display value ± 1%; 1. ESR test range: 0.0001 - 999.99m ; automatic shift from upper limit of setting value m , , K, M; display mode: LCD display precision: display value 1%; setting mode: it can set the range of gear and display the set value.
