The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
The schematic diagram of an embodiment of the overturn system that Fig. 3 provides for the utility model, Fig. 4 is the side view of Fig. 3, as shown in Figure 3, Figure 4, the overturn system of this embodiment, comprise trip shaft 1, and be arranged on the side of trip shaft 1 and can be around the roll-over unit 2 of trip shaft 1 rotation, roll-over unit 2 comprises framework 21, it is arranged on the plane at trip shaft 1 place; Connector 4, it is used for framework 21 is fixed to trip shaft 1, and framework 21 is provided support, and framework 21 and connector 4 also can be formed in one certainly; Two suckers 22, the direction that its edge is parallel to trip shaft 1 is arranged at the middle part of framework 21, and sucker 22 is used for silicon chip is adsorbed onto the surface of framework 21; A plurality of cushion blocks 231,232, its respectively a side of the close trip shaft 1 on the surface of framework 21 and away from a side of trip shaft 1 along the direction setting that is parallel to trip shaft 1, cushion block is configured to the silicon chip 3 that suction nozzle 22 is drawn is cushioned, supports and locatees.
The overturn system of this embodiment, two suction nozzles 22 that utilization is arranged in the framework 21 of roll-over unit 2 are drawn silicon chips 3, owing to only use two suction nozzles in the present embodiment, prior art has reduced 1/3 so the quantity of the suction nozzle that need adjust is compared, and the flatness of two suction nozzles ratio is easier to adjust, utilize a plurality of cushion blocks 231 in addition, 232 pairs of silicon chips of being drawn 3 carry out assist location, so it is stable that the horizontal level of silicon chip 3 easily keeps, also reduced workload, and when drawing silicon chip 3 and in switching process, a plurality of cushion blocks 231,232 pairs of silicon chips of being drawn 3 cushion, support and positioning action, silicon chip 3 can not shaken in whole switching process, can frictional impact not take place with other positions of overturn system, thereby reduce the fragmentation rate of silicon chip, and owing to only use two suction nozzles 22, be prior art use suction nozzle quantity 2/3, so reduced the cost of whole system.
The framework 21 of above-mentioned overturn system can be configured to the framework of similar H shape (if connector 4 is one-body molded with framework 21, two cross bars are then arranged), comprise vertical montant of two parallel and described trip shaft 211 and the cross bar 212 parallel with trip shaft 1, a plurality of cushion blocks 231,232 can comprise at least two cushion pieces 231 and at least two hard packing pieces 232, in the present embodiment to comprise that two cushion pieces and two hard packing pieces are that example describes, two cushion pieces 231 are arranged on the side of close trip shaft 1 on the surface of framework 21, promptly the side near trip shaft 1 all is provided with a cushion piece 231 on each the bar montant in two montants 211 of H shape framework 21, and two hard packing pieces 232 are arranged on the side away from trip shaft 1 on the surface of framework 21, promptly all be provided with on the cross bar 212 that 22 of 232, two suction nozzles of a cushion piece are arranged on H shape framework 21 away from a side of trip shaft 1 on each the bar montant in two montants 211 of H shape framework 21.Preferably, hard packing piece 231 and cushion piece 232 are cylindrical.Preferably, the cushion piece on same montant 211 231 is the axial symmetry setting with hard packing piece 232 with cross bar 212.
The framework 21 of above-mentioned overturn system can be provided with baffle plate 5 near a side of trip shaft 1, and for example L shaped baffle plate also can play the effect of support, location and protection to silicon chip 3 in silicon chip 3 switching processes.For example, can near a side of trip shafts 1 a L shaped baffle plate 5 be set all at each bar montant 211 of H type framework 21, one side baffle plate 5 be fixedly installed on the montant 211 be provided with vertical with another side.
Above-mentioned overturn system is in operating process, see on the macroscopic view that suction nozzle 22, cushion piece 231, hard packing piece 232 are to touch silicon chip 3 simultaneously, utilize suction nozzle 22, cushion piece 231,232 pairs of silicon chips 3 of hard packing piece to play support, location and cushioning effect then, make silicon chip 3 in absorption and switching process, keep stable, do not produce and rock, thereby other positions with overturn system do not produce frictional impact, reduce the fragmentation rate of silicon chip.From microcosmic; at first be that hard packing piece 232 contacts with silicon chip 3; because hard packing piece 232 is by the harder materials for support of material; therefore hard packing piece 232 is difficult for taking place deformation; a stable side that supports silicon chip 3; promptly away from a side of trip shaft 1; open suction nozzle 22 then, suction nozzle 22 holds silicon chip, and and then the cushion piece 231 near trip shaft 1 one sides contacts silicon chips 3; when silicon chip 3 contact cushion pieces 231; cushion piece 231 can be subjected to the impulsive force of silicon chip 3, thereby reacts on silicon chip 3, because cushion piece 231 is made by the softer material of material; therefore can reduce the impact of silicon chip; silicon chip 3 is played the effect of buffer protection, like this, hard packing piece 232; 231 pairs of silicon chips 3 of cushion piece all play the effect of assist location and support; silicon chip 3 is stably held by suction nozzle 22, thereby silicon chip can not shake in whole switching process.
In a word, the above is embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model, but is used to illustrate the utility model.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
