Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment is further described the utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, after the metallurgical blank of powder metallurgy press pressed powder completes, powder metallurgy blank 100 is positioned at press die cavity, blank unloading device horicontal motion mechanism 200 promotes grabbing assembly 210 and arrives blank 100 tops, upper and lower assembly 220 drops to grabbing assembly 210 and blank same level, grasping mechanism 210 moves, and blank is clamped.Then the blank backward B end motion of rising, blows away adhering to dust on blank through dust-blowing device 125,130,140, dust exhaust apparatus 105,110,120.
The effect of dust board 145 keeps off dust in casing 400 front portions, avoids affecting detecting unit.
For protection blank, on grasping mechanism and blank contact-making surface, cover elastomeric material, as rubber, EVA, PU, SBS, POE etc.
In order to ensure higher cleannes, arrange above drifting dust, the dust exhaust apparatus of 3 cover.
For reliably, powder metallurgy blank moves on road 3 road dust boards is set, and below arranges suction port, and top arranges drifting dust mouth.
Move blank left-side images sensor 150, blank image right sensor 170 and blank lower images sensor 160 are set in approach at blank.In the time of above three sensing stations of blank process, imageing sensor captured image passes to graphics processing unit 600 and processes.
Described imageing sensor 160 tops that are arranged on blank stroke horizontal movement direction below arrange dust-break glass plate 180 are also set, and can prevent that like this dust from producing and disturbing imageing sensor 160.
When detection, when blank 100 moves to B end by grasping mechanism, grasping mechanism drops to conveyer belt top, and grasping mechanism 210 discharges blank is placed on conveyer belt, blank front end face image sensor cell 360 is responsible for the crawl of blank front end face, and blank rear end face image sensor cell 310 is responsible for the crawl of blank rear end face, and blank upper surface image sensor cell 300 is responsible for the crawl of blank upper surface, when blank is through elementary area 300, 360, 310 o'clock, image is passed to graphics processing unit 600 by elementary area, graphics processing unit 600 receives that 6 image informations carry out dysnusia processing, if substandard products, send out substandard products signal to controlling organization 700, when receiving defective signal controlling rejecting mechanism, controlling organization 700 moves bad part eject, controlling organization 700 is according to transport tape and grasping mechanism positional information, calculate the rejecting mechanism action moment, reject substandard products, by bad part eject mechanism 500, the upper and lower mechanism 510 of bad part eject, bad part eject mechanism ejecting mechanism 520 is released substandard products to collect mouth 370, if non-defective unit is transferred to later process.
For reduce dust polluting environment prevent product oxidation with or fire, the casing 400 of the utility model embodiment is airtight casings, and is full of inert gas.
For avoiding spurious rays to affect elementary area, by dark box inside application coating, more before application, picture quality does not have marked improvement especially.
In view of LED reliability, the long-life, monochromatic light characteristic, each image sensor cell lighting unit preferentially adopts the illumination of LED dot matrix.
In order to ensure the cleaning of IMAQ part, require the air pressure of IMAQ part to be greater than drifting dust dust collection mechanism and baffle plate formation confined space especially.
In embodiment, B end pressure is greater than C end pressure and is greater than A end pressure.In order to ensure that B end pressure is greater than C end pressure and is greater than A end pressure, be provided with inert gas input port at B end, C end pressure relief opening is smaller compared with A end pressure relief opening aperture.
