In full band fixed plate 9；Base 18 is put back to compression chassis rapid fixing clamp 21 on working standard platform 13；Belt-strap is taken out
Go out, bracelet angle is adjusted out by ribbon angle adjustment optical axis 20 and bypasses locking after ribbon fixation clamp 25, by ribbon rapid fixing clamp
25 slide into the locking of ribbon real vehicle installment state position on A-frame 24；Joined by the actual tests that touch screen sets
Number, after PLC process, click start button.
(2) on-test：Air inlet pipe of dusting 17 carries out air blowing by powder injection hole 16 and is dusted, 5 seconds rear bars not rotary type
The ribbon on A-frame 24 in ribbon rapid fixing clamp 25 is driven to open from magnetic approach switch 2 29 with strength dust scraping ring cylinder 27
Beginning carries out downwards backrush campaign, touches magnetic approach switch 3 30 and starts to carry out pull-out campaign upwards, touches magnetic approach
Switching one 28 beginnings carries out downwards backrush campaign, if at the appointed time, rotary type band strength dust scraping ring cylinder 27 is not touched bar
Encounter magnetic approach switch 1, be then considered as seat belt and locking occurs, buzzer sends alarm sound while bar not rotary type band
Strength dust scraping ring cylinder 27 carries out downwards backrush campaign and stops at 3 30 position of magnetic approach switch, and protection seat belt is gentle
Cylinder.Complete to stop at 2 29 position of proximity switch after 10 ribbons pull out backrush motion cycle.Carried out once every 20 minutes
Dust backrush campaign, off-test after 5 hours are pulled out with 10 ribbons.
It should be noted that above-mentioned being for illustration only property of the specific embodiment explanation of the present invention or the original of the explanation present invention
Reason, and be not construed as limiting the invention.Therefore, that what is done in the case of without departing from the spirit and scope of the present invention any repaiies
