By adopting the device, plastic-sealed body strips of different thicknesses can be accurately distinguished.
Description
Technical field
The utility model relates to the plastic-sealed body thickness discriminating device in the semiconductor applications automatic cutting formation system.
Background technology
Along with the diversified development of integrated products, it is identical lead frame to have occurred in this field, and the plastic-sealed body profile is identical, and only plastic-sealed body thickness has the product of minute differences.When on producing, doing these two kinds of products simultaneously, have easily very much the two is obscured together.Therefore, before to the product punching molding, requiring has an ability with the two mechanism that makes a distinction in automatic cutting formation system material loading part.Because this singularity of profile; Common employed portrait processing and detecting can not make a distinction the two; Because in the automatic cutting formation system, generally (plastic-sealed body parallel surface) sampling and distinguish different stripes or defective band directly over band of portrait processing and detecting according to the image of surveyed area, area, color etc.When on the two profile when consistent, this detection method just can not give the two to distinguish.Equally, because the plastic-sealed body thickness phase missionary society very little (like 0.2mm) of the two, and lead frame itself is very thin, easy deformation, and therefore, the method that directly detects with pure mechanical position limitation or sensor also is difficult to realize, has brought very big inconvenience to production.
The utility model content
The purpose of the utility model is exactly to solve the problem that plastic-sealed body thickness has the product differentiation of minute differences, provides a kind of plastic-sealed body caliper zones to divide and detects device.
The technical scheme that the utility model adopts is: the plastic-sealed body caliper zones is divided the detection device; It is characterized in that it comprises mounting blocks, roller installation shaft, roller and proximity transducer; Described roller is fixed on the end of roller installation shaft; Be movably connected on the mounting blocks through fulcrum; Roller installation shaft fulcrum roller end length is less than fulcrum other end length, and roller installation shaft fulcrum roller end top is provided with holddown spring and is squeezed on the roller installation shaft, and roller installation shaft fulcrum other end top is fixed with proximity transducer.
Adopt technique scheme; Plastic-sealed body is when feeding guide process roller; The plastic-sealed body of different-thickness will make roller raise different height, because roller installation shaft proximity transducer end length is greater than opposite side length, make the height change that roller installation shaft proximity transducer end can amplify the other end; Show through proximity transducer again, reach the purpose of differentiation.
Excessive for preventing roller installation shaft rotational angle, the top of roller installation shaft is provided with stop screw.
For optimizing structure, the upper fixed of mounting blocks has the sensor installing plate, and sensor installing plate one end is provided with screw, and with the adaptive bolt of screw, holddown spring is set with the bottom of bolt in the screw.
Be convenient fixedly proximity transducer, above-mentioned proximity transducer is fixed on the sensor installing plate.
For the protection proximity transducer, be enclosed with the sensor protection cover on the proximity transducer.
Above-mentioned rollers installation shaft pivot sensor one side length is 5 times of other end length, and better district effect can be arranged.
In sum, the utility model beneficial effect is: the subtle change of having amplified plastic-sealed body through the roller installation shaft, so the utility model can better be distinguished the plastic-sealed body of subtle change.

Among the figure, 1, mounting blocks, 2, the sensor installing plate, 3, roller, 4, the roller stationary shaft; 5, roller installation shaft, 6, holddown spring, 7, the sensor protection cover, 8, the band back up pad, 9, bearing pin; 10, collar, 11, proximity transducer, 12, bolt, 13, stop screw, 14, feeding guide.
Embodiment
The utility model plastic-sealed body caliper zones is divided the detection device, and like Fig. 1, shown in Figure 2, it comprises mounting blocks 1, roller installation shaft 5, roller 3 and proximity transducer 11; Roller 3 is fixed on the end of roller installation shaft 5 through roller stationary shaft 4, is movably connected on the mounting blocks 1 through fulcrum, and present embodiment is to realize like this; On mounting blocks 1 and roller installation shaft 5, be provided with through hole; Penetrate bearing pin 9 in the through hole, the two ends of bearing pin 9 are fixed with collar 10, make roller installation shaft 5 to rotate around bearing pin 9.Roller installation shaft 5 fulcrum rollers 3 end length are 15 millimeters; Other end length is 60 millimeters; As shown in Figure 2, roller installation shaft 5 fulcrum rollers 3 ends top is provided with holddown spring 6 and is squeezed on the roller installation shaft 5, and roller installation shaft 5 fulcrum other end tops are fixed with proximity transducer 11.The upper fixed of mounting blocks 1 has sensor installing plate 2, and sensor installing plate 2 one ends are provided with screw, and with the adaptive bolt 12 of screw, holddown spring 6 is sleeved on the bottom of bolt 12 in the screw.The top of roller installation shaft 5 is provided with stop screw 13.Stop screw 13 thread connection are on sensor installing plate 2.Be enclosed with sensor protection cover 7 on the proximity transducer 11, sensor protection cover 7 passes through screw retention on sensor installing plate 2.
Band back up pad 8 is installed on the feeding guide 14, when band passes through roller 3, and squeezing roller 3, roller installation shaft 5 other end displacements are bigger, thereby realize distinguishing the plastic-sealed body of different-thickness.
Know by figure; Because being roller to the distance L of pivot point, proximity transducer 11 (can design multiple as required to 5 times of the distance H of fulcrum; Guarantee between the plastic-sealed body gap amplify the back sensor can stable detection to); So the gap (0.2mm) of plastic-sealed body also will be exaggerated 5 times, 1mm has reached near the stable detection scope, and proximity transducer 11 just can accurately detect Different products like this.The design of roller 3 is a benchmark with thin plastic-sealed body, the adjustment of adjustment spring bolt 12, stop screw 13 and proximity transducer 11, and after assurance roller 3 touched band, proximity transducer had signal output.And when roller 3 touches the thicker product of plastic-sealed body, roller 3 will on move, the distance of the other end of roller installation shaft 5 and proximity transducer 11 will increase, two kinds of Different products are so just distinguished in the output of proximity transducer 11 no signals.
Along with the development of semicon industry, the kind of product will get more and more, and the application of this testing agency will be more and more widely.
