(5) embodiment
In order to effectively reduce the ratio of loader part turn-over when driving strip and advancing, the present inventor experimentizes at existing loader on the line and observes, to seek the reason that causes the surface stuck part to produce turn-over in feeder process.In the process of checking repeatedly, find to cause a main cause of electronic component turn-over, be peeling off shell fragment and can press the side that contacts electronic component on the loader, and make it that situation of rollover take place easily.
Please refer to Fig. 3, this figure has shown and has peeled off the situation that shell fragment 16 is urged to electronic component 20 on the strip 14.By can obviously finding out among the figure, when being torn off backward by strip 14 upper surfaces, adhesive tape 18 divests, and when exposing the electronic component 20 that is arranged in the strip groove, what tightly be pressed against adhesive tape 18 and strip 14 tops peels off shell fragment 16 leading edges, can directly be urged to the side of electronic component 20, and its opposite side has upwards been lifted up.Add that strip 14 is that transmission track along supply disk advances fast, therefore under the situation of fast moving, spring takes place and causes the situations of rollover in electronic component 20 easily.
In order to solve the above-mentioned problem that shell fragment 16 leading edges are urged to electronic component 20 of peeling off, the present invention proposes a kind of new-type elastic piece structure of peeling off, and in the hope of when divesting adhesive tape, also can effectively prevent the part generation turn-over in the stopping materials strip groove.Please refer to Fig. 4, this figure has shown the disclosed shell fragment 22 of peeling off.It is to be applied to (please refer to Fig. 1) in the electronic component loader 10 that this kind peeled off shell fragment 22, in order to replace traditional shell fragment 16 of peeling off.As above-mentioned, this peels off shell fragment 22 is to be pressed against strip and adhesive tape top, when strip moves forward, can adhesive tape be divested backward, and expose the electronic component that is arranged in the strip groove one by one along the front end of peeling off shell fragment 22.
As shown in FIG., this peels off shell fragment 22 is sheet structures for a strip, and its front end has " U " font opening 221, the phenomenon that produces turn-over so that each electronic component when peeling off shell fragment 22 front ends, can not be subjected to peeling off the compressing of shell fragment 22.With the shell fragment 22 of peeling off in scheming is example, its " U " font opening 221 comprises that a diameter is the semicircle circular arc (radius R=0.9mm), and should the semicircle circular arc and peel off the spacing (spacing X=0.4mm among the figure) that about 0.4mm is still arranged between the shell fragment front edge of 1.8mm.Like this, no matter what carry out feed is that ((1 * 0.5 * 0.35mm) electronic component, " U " font opening 221 can both allow the electronic component in the strip groove to pass through smoothly to 1.6 * 0.8 * 0.45mm) or 0402 dimensions to 0603 dimensions.Peel off the front end of shell fragment 22 this moment, only can be urged to the upper surface of strip and adhesive tape, and conveniently tear off adhesive tape, and can not touch electronic component fully.
Please refer to Fig. 5, this figure shows to utilize and peels off shell fragment 22 and divest adhesive tape 18, to expose the situation that is arranged in strip 14 groove electronic components 20.Find out by knowing among the figure, when electronic component 20 when peeling off shell fragment 22 front ends, the design of " U " font opening 221 can be avoided peeling off shell fragment 22 and press and contact electronic component 20, and effectively be reduced the situation that electronic component 20 produces rollover, spring.In other words, because the A/F (being 2R) of " U " font opening is slightly larger than the length of electronic component, be with when electronic component passes through " U " font opening, can not be stripped from shell fragment 22 fully and be pressed onto.
In general, the design of above-mentioned " U " font opening 221 is can allow whole electronic component by for considering.Yet, when " U " font opening is wide, can reduces and peel off the effect that the shell fragment front end tears off adhesive tape.Therefore, in preferred embodiment of the present invention, the diameter of the semicircle circular arc of above-mentioned " U " font opening 221 inboards should be controlled between 1.6 to 2.0mm; And this semicircle circular arc and the spacing of peeling off the shell fragment front edge preferably are controlled between 0.4 to 0.5mm.
Peeling off on the shell fragment 22 of " U " font opening 221 rear sides, and has a horizontal finedraw opening 222.This finedraw opening 222 also can be used as and divests tearing off a little of adhesive tape, but only for being used for partly more special strip.As for, on the long side of peeling off shell fragment 22, then have always to the long and narrow flange 223 that extends, stretch and protrude from the front edge of peeling off shell fragment 22 to the forward position along peeling off shell fragment 22 sides.This long and narrow flange 223 can be in the feed program, presses and puts the side edge surface of strip, and make things convenient for strip and adhesive tape separated from one another, also avoids the whole piece strip to produce the phenomenon that turns down simultaneously.In addition, peeling off on shell fragment 22 rear side surfaces, then having two screws 224, be locked in the electronic component loader so that this is peeled off shell fragment 22 by screw.
With above-mentioned when peeling off shell fragment 22 and being bonded in the existing loader, the present invention also can provide a kind of effective reduction part to produce the loader of turn-over situation.Wherein, this loader has comprised a supply disk, and has on the side of supply disk and be used for driving the delivery track that strip advances.As for upper surface, have with the fixed intervals grooves distributed, and in each groove, all put an electronic component at strip.At the upper surface of strip, and attached an adhesive tape,,, and prevented that it is in the process of carrying, by dropping out in the groove in order to the protection electronic component to form airtight recess space.As for the described shell fragment 22 of peeling off, then can be pressed against strip and adhesive tape top, when strip forwards, can be along the front end of peeling off shell fragment, adhesive tape torn off backward divest, and expose the electronic component that is arranged in the strip groove one by one.Because, peel off the front end of shell fragment 22, have " U " font opening 221, so each electronic component that passes through, all be unlikely the front end compressing of being stripped from shell fragment 22 and cause turn-over.
Utilization disclosed peel off shell fragment in loader after, the open design of " U " font, can reduce really part when charging, be subjected to peeling off shell fragment compacting produced turns over the part situation.For example, utilizing traditionally when peeling off shell fragment 16 and carrying out the surface mount processing procedure, part turns over the part fraction defective and is approximately 21Dppm (21/1000000ths); Yet, utilize of the present invention when peeling off shell fragment 22 and carrying out the surface mount processing procedure, the turning over the part fraction defective and can be reduced to 10Dppm (10/1000000ths) of part.Like this, the yield of integral surface adhesion process be can improve, and maintenance and the spent artificial and cost of renewal part reduced.
Though the present invention illustrates as above with preferred embodiments, yet it is not in order to limit spirit of the present invention and scope.Person skilled in the art person is when understanding and utilize other element or mode to produce identical effect easily.Therefore, the modification of being done in not breaking away from spirit of the present invention and scope all should be included in the following claim institute restricted portion.
