In combination with the above description and the above drawings, the operation principle of the tray turning manipulator 4 for turning the tray will be described as follows:
in an initial state, the vibration disc cylinder, the lower plate cylinder 476 and the disc separating cylinder 474) retract, and the other cylinders extend; the upper plate 472 is above. When the material tray needs to be turned over, firstly, the vertical moving mechanism 44 drives the claw hand 46 to descend to an empty material tray position, and the holding plate cylinder 45 drives the claw hand 46 to hold an empty material tray and then ascend; simultaneously, the upper plate cylinder 473 is folded with the upper plate 472; the tray separating cylinder 474 extends to position the trays in the upper layer. Then the tray separating cylinder 474 drives the claw 46 to open, and the vertical moving mechanism 44 rises; while the claw 46 is lifted away. At this time, the empty tray is held by the turnover jig 47. Then, the rotating device 478 drives the overturning jig 47 to overturn, so that the empty tray is overturned by 180 °. Then, the vertical moving mechanism 44 drives the claw 46 to descend, the claw 46 holds the turned empty tray, then the tray-dividing cylinder 474 retracts, and the claw 46 drives the empty tray to be placed back to the original position of the empty tray. Then, the vertical moving mechanism 44 is raised, and the rotating device 478 is reset. After that, the claw 46 descends to pick and place the empty tray on the upper layer of the turnover jig 47 again. The transverse moving mechanism 42 drives the turnover jig 47 to move to the upper part of the full tray. The empty tray on the gripper 46 is then placed on top of the full tray to stack the two trays. Then, the claw 46 descends to grab two trays and ascends (an empty tray is arranged above and a full tray is arranged below); at this time, the lower plate cylinder 476 and the tray dividing cylinder 474 extend to make the lower plate 475 extend to support the lower tray, the tray dividing cylinder 474 clamps the upper tray, meanwhile, the pressing cylinder 479 drives the pressing plate 4791 to make the pressing plate 4791 abut against the lower plate 475, and finally the lower plate 475 presses the two trays. Then, the claw 46 is released to lift and avoid, and the rotating device 478 drives the jig to turn over, so that the two trays turn over by 180 °. At the moment, a full-load tray is positioned above, an empty tray is positioned below, meanwhile, the tray vibrating cylinder vibrates and strikes the tray, so that the chip is turned over from the full-load tray above to the empty tray below (the bottom surface of the chip is downward), finally, the claw 46 descends to hold the two trays, the pressing cylinder 479 is loosened, then the lower plate 475 is opened, and the claw 46 drives the full-load tray to descend to be placed on the lower tray conveying mechanism 3.
The working principle of the chip detecting and sorting machine 100 of the present invention is described below with reference to the above drawings, as follows:
firstly, a tray full of chips (with the bottom surface of the chips facing upward) is manually placed on the tray stacking jig 12 of the first tray feeding mechanism 1, and an empty tray is also manually placed on the second tray feeding mechanism 2. Then, the jacking mechanism 16 jacks and carries the material tray, and the tray dividing mechanism 13 contracts to separate from the material tray. The jacking mechanism 16 then moves down a distance of one tray height. At this time, the tray separating cylinder 474 of the tray separating mechanism 13 extends, and the tray separating inserting plate is inserted between the lowest tray and the tray on the lowest tray, so that the tray on the lowest tray is separated from the tray on the upper tray. At this time, the jacking mechanism 16 drives the material tray at the lowest layer to descend and enables the material tray to be borne on the seat body, and at this time, the front chuck plate cylinder and the rear chuck plate cylinder sequentially extend out to clamp and position the material tray. The chuck driving mechanism 15 may drive the chuck mechanism 14 to move toward the other end along the track groove 11. When moving to the below of first visual detection device 6 and second visual detection device 7 in proper order, the induction system response back that corresponds, chuck actuating mechanism 15 stops, at this moment, first visual detection device 6 shoots the detection to the chip on the charging tray, second visual detection device 7 shoots the detection to the chip on the charging tray to with the result record to control system on. Then, the chuck driving mechanism 15 drives the chuck mechanism 14 to move again, the chuck mechanism 14 reaches the other end of the track groove 11 after the height limit detection of the height limit optical fiber, the tray is released by the chuck mechanism 14, and then the buffer jacking mechanism 17 jacks the detected tray to the buffer supporting block 18 to receive the tray, so that the tray is stacked. Meanwhile, the second feeding tray conveying mechanism 2 conveys the unloaded tray to the other end thereof. At this time, the material tray turning manipulator 4 transfers the empty material tray to one of the lower material tray conveying mechanisms 3, turns over the full material tray on the first upper material tray conveying mechanism 1 and transfers the full material tray to the other lower material tray conveying mechanisms 3 respectively, so that two lower material tray conveying mechanisms 3 are provided with material trays full of chips, and the other lower material tray conveying mechanism 3 is provided with an empty material tray. Thereafter, each of the tray transfer mechanisms 3 transfers the tray to a position below the sorting robot 5. At this time, the third and fourth visual inspection devices 52 and 53 sequentially inspect the chips, and then the sorting robot 5 sorts the chips. Specifically, the control system divides the chips into at least two types, for example, a qualified type and an unqualified type, according to the result of the visual detection, so as to control the sorting manipulator 5, place the first type of chips on a tray on one of the blanking tray conveying mechanisms 3, and place the second type of chips on a tray on the other blanking tray conveying mechanism 3, so that the same type of chips can be placed on the same tray. When each material tray is full, the material tray is conveyed to the discharging end by the corresponding discharging tray conveying mechanism 3 on the material tray, and is stacked on the material tray stacking jig to wait for taking out. When no material tray exists on the lower material tray conveying mechanism 3, the material tray overturning manipulator 4 transfers the full-load material tray on the first upper material tray conveying mechanism 1 to the lower material tray conveying mechanism 3; or the empty tray on the second upper tray conveying mechanism 2 is transferred to the lower tray conveying mechanism 3, so that sorting can be continuously carried out.
Compared with the prior art, because the utility model discloses a set up first charging tray conveying mechanism 1 to the charging tray material loading that is full of carrying the chip, then first charging tray conveying mechanism 1's middle part sets up first visual detection device 6 and second visual detection device 7, utilizes first visual detection device 6 and second visual detection device 7 carry out visual detection to the reverse side of the chip on the charging tray to can detect out the difference of each chip. And then, arranging a second feeding tray conveying mechanism 2 and a plurality of feeding tray conveying mechanisms side by side, turning over the feeding tray full of chips by using the second feeding tray conveying mechanism 2 and the feeding tray turning manipulator 4, transferring the turning tray full of chips onto the discharging tray conveying mechanism 3, and finally detecting the front surfaces of the chips by using the third visual detection device 52 and the fourth visual detection device 53, classifying the chips by using the sorting manipulator 5 and transferring the chips of different types onto different discharging tray conveying mechanisms 3. Therefore, the utility model discloses chip detects sorter 100 need not the manual work and detects and classify, and whole process from last charging tray, detection, sorting and unloading are all accomplished automatically, and degree of automation is high, greatly reduces intensity of labour, improves production efficiency.
