Preferably, multi-degree-of-freemechanical mechanical arm 21 is preferably the three-freedom mechanical arm of XYZ axles, and it can drive CCD camera lenses 22
The movement of horizontal two-freedom and vertical direction is realized, and CCD camera lenses 22 are moved to the surface of carrier 30.
In the technical scheme, to carry out IMAQ to the circuit board on carrier 30, the image of collection passes CCD camera lenses 22
Deliver to single-chip microcomputer and carry out image procossing, judge whether pcb board surface glue surface covers completely.
In the technical scheme, the both ends of carrier 30 are respectively supported on the first guiding band 13 and the second guiding band 14, are passed through
Frictional force drives carrier 30 to move.First guiding band 13 and second guides the clearance space between band 14 to place jacking apparatus
40, the area to be detected 11 of the surface of the jacking apparatus 40 as carrier 30, due to more between the conveyer belt 10 of carrier 30 and first
There can be displacement error less, particularly laterally (vertical direction of transfer), after carrier 30 reaches area 11 to be detected, pass through stopper
50, which limit it, is continued to move to, and jacking apparatus 40 rises, and the positioning hole of carrier 30 is correspondingly slipped on keeper 43, so as to realize to carrying
Tool 30 is accurately positioned, and after positioning, is driven CCD camera lenses 22 to be moved to area 11 to be detected by mechanical arm and is carried out IMAQ.
Keeper 43 is to realize the support and positioning to carrier 30, and in a preferred embodiment, keeper 43 is set
There are 4 of rectangular arrangement.
In one embodiment, stopper 50 is cylinder, and the cylinder is fixed on the first guiding band 13 or second and guides band 14
Side, it can protrude from the upper surface of the first conveyer belt 10, and carrier 30 is blocked in into 11, area to be detected in upward stretch out
In one embodiment, keeper 43 has smooth chamfering, and positioning hole is equipped with tapered inner surface, can be so as to
In realizing fast positioning.
Further, formed with least one pcb board locating slot 31 on carrier 30.
