Description

Drill bit grinding device with ring position calibration function

One, technical field

The utility model relates to drill bit grinding device, relates in particular to the operation that a kind of sharp keen again grinding that can make the drill bit that is arranged with locating ring and locating ring are adjusted calibrating position, the drill bit grinding device of can a serialization finishing automatically with ring position calibration function.

Two, background technology

In the boring preparation process of printed circuit board (PCB), in order effectively to control the drilling depth of drill bit, as shown in Figure 1, generally be that shank at drill bit 1 is arranged with a locating ring 2, the apical margin 2a that utilizes this locating ring gets accurate position foundation when boring as drilling machine main shaft 3, and cooperate the default absolute distance h of the apical margin 2a of this locating ring to the drill lip tip, reach the purpose and the effect of the accurate keyhole degree of depth.Moreover, drill bit is after suitable number of drills, all can cause the relative wear consumption at drill lip position, in order to take into account the boring precision and the economic benefit of printed circuit board (PCB), general practitioner all can adopt again the mode of abrasive drill, the original sharpness of a large amount of drill bits in the reasonable time of recovering to use uses this drill bit heavily covering.

Because the drill lip end of drill bit can cause the locating ring on the drill body to lose original preset standard position after sharp keen grinding again, therefore, the drill bit after grinding again must be adjusted a calibration positioning operation through the ring position again, and use can be provided; Be manually to move the material mode at present, the drill bit to be ground of locating ring will be with, be transferred to drill bit stone grinder place earlier and carry out again sharp keen processing procedure, drill bit is transferred to the last ring machine place with throw-out collar function and encircles adjustment calibration location, a position processing procedure after will grinding again, this prior art means, though can reach the implementation result that drill bit is sharp keen again and the adjustment calibration of ring position is located, yet the material process of moving that it is complicated, cause some whole preparation process efficient effectively to improve, reach problems such as the device space and cost demand are bigger.

Sharp keen again at above-mentioned existing drill bit, adjust the not good problem of calibrating position processing procedure efficient, this case creator formerly develops successively No. the 9,421 8819, domestic patent application, the novel patent of " drill grinder checkout gear " (calling in the following text) with reference to case one, and " feed arrangement of drill grinder " novel patent (calling in the following text) of No. 95200324 with reference to case two, wherein should be with reference to case one, provide the design that combines of a kind of grinder and optical sensing apparatus, with the amount of grinding control of drill bit before reaching effective raising and grinding and the purpose and the effect of the sharp keen again quality testing precision of grinding the back drill bit; And, provide a kind of drill bit input and output material operation that can impel with reference to case one with reference to case two, can reach purpose and effect that automation is finished continuously.

Above-mentioned with reference to case one, two, though can effectively improve the real drawback of dragging efficient of existing lapping device shortcoming, yet, when if it apply to be arranged with the drill bit of locating ring, still need to be collected into last ring machine place in addition with throw-out collar function with grinding the back drill bit, carry out the locating ring of above-mentioned indication and adjust the calibrating position operation, therefore, still have its utility function to treat improved space.

Three, utility model content

Main purpose of the present utility model is to overcome the above-mentioned shortcoming that existing product exists, and a kind of drill bit grinding device with ring position calibration function is provided, include the sharp keen again grinding unit of optical sensing apparatus, drill bit and be set in ring position calibrating installation on the drill bit, make and grind the sharp keen again quality testing while that the back drill bit carries out drill lip, can be by ring position calibrating installation in the lump with the calibration of the locating ring adjustment on drill body location, the sharp keen again of drill bit and the calibration of ring position are accomplished without any letup, more efficient.

The purpose of this utility model is realized by following technical scheme.

The utlity model has the drill bit grinding device of ring position calibration function, it is characterized in that, comprising: an optical sensing apparatus, it has the to be ground and image optics sensing component that grinds the back drill bit of at least one picked-up location; One is ground unit, its have for drill bit plant the location put boring anchor and in order to the emery wheel of sharp keen drill bit again, this is put boring anchor and moves around between an initial position and a final position, and can relatively move with emery wheel, and the drill bit that is carried is ground; A ring position calibrating installation is provided in a side of capture place of optical sensing apparatus, and it has one and the compacting of the locating ring on the drill bit pushed against the band driver of putting the boring anchor apical margin and one drill bit to be raised most advanced and sophisticatedly to drill lip pushes away the brill device till arriving position height surely; Make when grinding the back drill bit and be moved to optics sensing component place and make a video recording, also finish the operation that locating ring on this drill bit is adjusted calibrating position synchronously.

Aforesaid drill bit grinding device with ring position calibration function, wherein the image of optics sensing component picked-up is directly to be presented at screen to compare, analyze for vision, or by computer every data are compared, analyzed to the image of picked-up.

The beneficial effect that the utility model provides has a drill bit grinding device of ring position calibration function is, its include one can absorb to be ground with grind the back drill bit image for analyzing and the optical sensing apparatus of comparison, can be readjusted the ring position calibrating installation of calibrating position with being set in locating ring on the drill bit for the sharp keen again grinding unit of drill bit and; By this device, drill bit is moved to the sharp keen again quality testing while that the optical sensing apparatus place carries out drill lip after grinding, can the sharp keen again of drill bit and the calibration of ring position be accomplished without any letup by ring position calibrating installation in the lump with the calibration of the locating ring adjustment on drill body location, more efficient.
