In addition,, for described pick-up head, it further comprises jaw 16, flexible stylet 17 and softProperty conductive head 18, wherein this jaw 16 is for example the structure with two pawls, described in it is coaxially arranged onThe downside of horizontal synchronization band 15, for providing the chucking power of pick-up head to element to be checked; This flexible stylet17 insulating mounting, in the bottom of described jaw 16, are carried out the same of flexible contact for guaranteeing to element to be checkedTime, also realize the electric detection to element to be checked; 18, this compliant conductive head is wrapped in each flexible spyThe end of pin 17, and for there is suitable distortion in the time contacting with element to be checked, increase thus this and leadContact area between dateline and element to be checked, and guarantee to realize stable with the pin of element to be checkedBe communicated with;
More particularly, referring to Fig. 6, the flexible stylet of insulating mounting on two fingers of jaw, byIn the time that it has certain flexibility therefore at gripping element, can realize flexible contact, reduce elementDamage, in addition the probe other end can be connected with LCR measuring instrument by wire then synchronize realize to unitThe detection of part; Compliant conductive head 18 is wrapped in the end of flexible stylet, like this meeting in the time contacting with elementThere is appropriate distortion, increase the reliability that conductive head is communicated with component pin, and guaranteed conductive headCan realize stable being communicated with the pin of various elements.
Referring to Fig. 4, as another key improvements point of the present invention, described charge module 2 comprises unit to be checkedPart material holding tray 21, trash receptacle 22 and crisp dish 23, this three is all arranged on table surface, and excellentChoosing is set on same straight line, so that the quick location of manipulator; Wherein this element to be checked is containedCharging tray 21 is for holding the element to be checked stripping down from described material strip, and installs in its cardThere is loose and porous structure 24, for adapting to the absorption of different size element to be checked; This trash receptacle 22 forUnderproof element after holding after testing, this crisp dish 23 for example can be designed to moulding of many rectangular arrays holeCharging tray, for qualified element after holding after testing.
More specifically, referring to Fig. 7, shown the solid knot of element material holding tray to be checked and loose and porous structureStructure and full sectional view. As shown in the figure, keep its attitude constant in order to adsorb element to be checked, at material holding trayCard on manufactured some negative pressure of vacuum pore 21a; Under negative pressure pore, be the air chamber 21b that holds gas,The bottom airtube 21c for air feed.
In addition, according to the preferred embodiment of the present invention, the said equipment can also be equipped with supplementary module 5,This supplementary module mainly comprises ion wind generator 51, display unit 52, human-computer interaction device 53 etc.;Wherein ion wind generator is eliminated for detection of region static; Display unit and human-computer interaction device are usedIn realizing the real-time demonstration in Whole Equipment operating process and controlling in real time.
The main running of inspecting and check equipment according to SMD of the present invention by random samples will simply be introduced below.
First, the front several elements on SMD charging tray are peeled off, put into unit to be checked by peeling the element comingPart material holding tray, is then placed in SMD charging tray on blowing end and prepares to check;
Then, five axis robot under look under the guiding of camera, pick up the element to be checked in material holding tray,And synchronously realize the detection of element, afterwards by qualified component as for crisp dish, defective element is as for waste materialBucket;
Finally, material retractable end motor drives material strip by sensor, measures the number of element on material strip,And quantitatively cut in the situation that having demand.
With reference to Fig. 8, show that pick-up head picks up the attitude of detection pin in the time of the element of side. As scheme instituteShow, under depending on camera, element is accurately located after, the attitude of manipulator adjustment oneself is led flexibilityDateline is from both sides near element, then after contacting with element, the raw appropriate distortion of compliant conductive hair, to weekTouch reliably component pin thereby enclose expansion, last clamping element picks up detection.
With reference to Fig. 9, show that pick-up head picks up the attitude while detecting the superincumbent element of pin. As figureShown in, under depending on camera, element is accurately located after, the attitude of manipulator adjustment oneself makes flexibilityConductive head is from above near element, then after contact with element, compliant conductive hair is raw to be out of shape in right amount, toThereby expansion touches component pin reliably, then driving jaw to step up element around. But needIt is to be noted, Fig. 8 and Fig. 9 just analyze the pick process of two kinds of typical elements, otherDissimilar element also can be realized and be picked up and detect by similar mode.
In general, inspect by random samples and check equipment compared with prior art according to SMD of the present invention, passing throughTo the specific aim research and design of Whole Equipment and modules, can realize the quick sampling observation towards charging trayWith check, and synchronously realize picking up and detecting operation of element, and possess that efficiency is high, strong adaptability,The advantages such as testing result is accurate.
Those skilled in the art will readily understand, the foregoing is only preferred embodiment of the present utility modelOnly, not in order to limit the utility model, allly within spirit of the present utility model and principle, doAny amendment, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
