仪器说明：
本仪器依据客户的DC线测试标准080-1276-K中第7.12章要求设计加工，主要用于检测DC电线的抗座椅脚轮碾压能力。模拟办公室座椅的脚轮在电线上反复碾压，以此判断电线抗碾压的次数寿命。采用电机驱动，仪器带有不良品判断功能，当产品被碾压后而导致电线屏蔽层或导体与金属板接通时，仪器自动停机，并保持和记录碾压次数，并声光报警输出。
主要技术参数：
1、 控制系统：触摸屏+PLC+伺服电机
2、 金属板移动速度：200mm/s
3、 金属板尺寸：30 cm x 60 cm (12 inches x 24 inches)
4、 碾压重量：25kg（可根据需求改变）
5、 碾压次数：0~99999次可设定
6、 碾压轮要求：办公室用座椅轮，可360度转动
7、 判断方式：低压信号电流判断
8、 合格/失败判断标准：连续碾压1250次未与金属平面短路，或本身开路则合格，反之为失败。
9、 夹具中心宽度：250mm
10、 电源:：AC 22V 50Hz 500W
外形尺寸：850mm×600mm×750mm（宽×深×高）
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)
