When reference Fig. 1 and even Fig. 3, the Integrated Check out System 10 of the present invention's the 1st embodiment be can to inspection objects 20 such as the film (film) of continuous formation flexible PCB unit, tape (tape) type utilize the automatic pattern Processing inspection of a plurality of shoot parts and visual examination and also not the good merchantable brand image confirm the system that reexamines of (Verify).
Integrated Check out System 10 comprises feeder 100 (feed roller, loader), inspection portion 300, coiled strip portion 200 (winding roller, unloader) and the control part 900 of controlling the many actions of these textural elements.
Have the object 20 of inspection to be wound on the spool 110 in the feeder 100, the inspection object of sending from feeder 100 20 passes through the bending handover portion 310 that offers inspection portion 300 to deflector roll 120.Check that object 20 is wound on the spool 210 of coiled strip portion 200 through inspection portion 300.
When reference Fig. 2 and Fig. 3, inspection portion 300 comprises crooked handover portion 310, pattern inspection portion 320, visual examination portion 330 and not good image confirmation unit 340.
Bending handover portion 310 has the support sector 312 that supports to check object 20, and this support sector 312 makes to transfer along the circumference configuration with certain radius circular-arcly and checks object 20.Support sector 312 comprises 1 group of support roller 314 that mutual isolation is provided with.In inspection portion 300, check the path handover of object 20 by making along bending, compare with the handover length that linearity is transferred under the situation of checking object 20, will relatively prolong handover length, therefore the shoot part of a plurality of quantity can be set with not interfering mutually.Usually in the camera of shoot part, the adjustment component b that fixed support (bracket) a and being used to adjusts position of camera is set to 1 group, therefore requires the installing space greater than the camera size.
