Description
Technical field
The utility model relates to a kind of cutter sweep of electrostatic protector, is specifically related to positive conducting shell single cutter sweep of a kind of electrostatic protector.
Background technology
In the positive conducting shell cutting process of electrostatic protector, the object of laser is that positive conducting shell preceding working procedure printed cuts off, and laser cutting is in the past all the mode adopting cutting continuously, by the disposable cut-out of just conductor of whole piece many electrostatic protectors.But be cut with shortcoming continuously: the groove that laser cuts formation on ceramic substrate can extend through substrate edges; comprise conductor and there is no the position of conductor; in follow-up manufacturing process, print protective layer can affect combination between protective layer and substrate; cause the aqueous vapor in air easily to invade the functional layer of electrostatic protector from groove, cause the leakage current ultra-specification that electrostatic protector generation causes because of moisture-proof problem.
Summary of the invention
The utility model object is: positive conducting shell single the cutter sweep providing a kind of electrostatic protector, solve the problem that groove cuts to substrate edges, the moisture resistance properties of product has clear improvement.
The technical solution of the utility model is: positive conducting shell single cutter sweep of a kind of electrostatic protector, comprises substrate, locating platform, camera, linear electric motors, laser instrument and automated optical inspection; Described substrate is positioned on described locating platform, and described camera is positioned at directly over described substrate, and described linear electric motors connect described laser instrument.
Further, described camera comprises ccd image sensor, and the pixel of described ccd image sensor is 2,900 ten thousand pixels, and the light source of described camera is the adjustable LED-backlit formula light source of brightness.
Positive conducting shell single cutting method of electrostatic protector, comprises the following steps:
Step 1) described camera is placed in directly over described substrate, be X by described locating platform, Y-direction moves, described substrate is taken pictures, the actual size that piece image is corresponding is 17.5mm*12mm, get three angle bat figure of described substrate, calculate with the position of 3 width images to the printed conductor on the position of described substrate and described substrate, to reach the consistent of described substrate and described linear electric motors movement locus, and calculate the downward shift amount of described printed conductor position;
Step 2) image processing algorithms is by calculating the positional information of described substrate edges, the breakaway line on described substrate and the described printed conductor on described substrate, with reference to UE resistance technological requirement, calculate the data of location, comprise: a) angle rotates: rotate described locating platform, make the breakaway line on described substrate and described linear electric motors angle be less than 0.002 degree and keep this position of rotation; B) position is moved: the horizontal level calculating described printed conductor, when this horizontal position is equipped with downward shift, calculate actual position, the upper-lower position side-play amount then described printed conductor being positioned at the described ccd image sensor of described camera is all transformed on described linear electric motors coordinate;
Step 3) described linear electric motors start to guide described laser instrument to carry out single cutting by the positional information that the described ccd image sensor of described camera obtains, adopt the mode of laser instrument described in good time switch, only cut the conductor part of described substrate, the substrate portion of described substrate is not cut; After cutting knife completes, when the somewhere that described automated optical inspection measures described substrate is bad, laser carries out mark destruction to it.
The utility model has the advantages that: the utility model is undertaken taking pictures by camera and carries out the algorithm location of image processing, adopt the mode of in good time switch laser, only cut conductor part, blank substrate part is not cut, substrate can not be scratched, ensure the seal after its follow-up printing protective layer, the moisture resistance properties of product is had clear improvement; When automated optical inspection detects that a certain material is bad, laser carries out mark destruction to it, can reject in follow-up inspection bag to it, thus reaches the object of not hindering substrate, not affecting air-tightness, improving yield.
