1、 控制系統(tǒng)：觸摸屏+PLC+伺服電機(jī)
2、 金屬板移動(dòng)速度：200mm/s
3、 金屬板尺寸：30 cm x 60 cm (12 inches x 24 inches)
4、 碾壓重量：25kg（可根據(jù)需求改變）
5、 碾壓次數(shù)：0~99999次可設(shè)定
6、 碾壓輪要求：辦公室用座椅輪，可360度轉(zhuǎn)動(dòng)
7、 判斷方式：低壓信號(hào)電流判斷
8、 合格/失敗判斷標(biāo)準(zhǔn)：連續(xù)碾壓1250次未與金屬平面短路，或本身開路則合格，反之為失敗。
9、 夾具中心寬度：250mm

Instrument Description:
This instrument is designed and processed in accordance with the requirements of Chapter 7.12 of the customer's DC line test standard 080-1276-K, which is primarily used to detect the anti-seat caster rolling capability of the DC wire. The caster wheels of the simulated office seat are repeatedly rolled over the wire to determine the number of times the wire is resistant to rolling. The instrument is driven by a motor, and the instrument is provided with a defective product judgment function. When the product is rolled, the wire shielding layer or the conductor is connected with the metal plate, the instrument is automatically stopped, and the rolling times are maintained and recorded, and the sound and light alarm is output.
Main technical parameters:
Control system: touch screen PLC servo motor
Speed of metal plate movement: 200mm/s
Plate size:30 cm x 60 cm (12 inches x 24 inches)
Rolling weight:25 kg (can be changed according to requirements)
Rolling times:0-99999 times can be set
Rolling wheel requirements: seat wheel for office,360-degree rotation
Judgment mode: low voltage signal current judgment
The criterion of qualification / failure: 1250 times of continuous rolling without short circuit with metal plane, or if the circuit itself is open, it is qualified, on the contrary, it is failure.
Fixture center width: 250mm
Power supply: AC 22V 50Hz 500W
Shape size: 850mm × 600mm × 750mm (width × depth × height)
