Example 2

With continued reference to fig. 1 to 4, the automatic stacking device of the present embodiment is disposed at a blanking station of the chip detection apparatus, and is configured to blank a tray carrying chips. That is, the rotation direction of the conveying mechanism 2 in this embodiment is opposite to that in embodiment 1, namely, the material tray is firstly received, then the material tray is conveyed, and finally the material tray is stacked.

Positioning mechanism 5 sets up the pan feeding end at stack mechanism 4, and when the charging tray was in the pan feeding end, positioning mechanism 5 was fixed the position of charging tray earlier, gets by the outside again and puts the equipment and place the chip on the charging tray, treats that the charging tray fills with the back, and conveying mechanism 2 moves and transmits the charging tray to the discharge end, and final elevating system 3 piles up the charging tray with the cooperation of stack mechanism 4. Furthermore, the position of the chip can deviate in the early detection and taking and placing processes, so that the chip can deviate when the chip is placed in a material tray of a feeding end by external taking and placing equipment, and the chip cannot accurately fall into the cavity. Therefore, as shown in fig. 1 and 3, the positioning mechanism 5 of the present embodiment further includes a side pushing cylinder 52 disposed on the stack holder 1 at the side of the tray.

after the feeding end of the conveying mechanism 2 receives the material tray, the diagonal positioning cylinder 51 pushes the material tray to position the material tray. And then, the chips are placed into the tray one by an external taking and placing device. Meanwhile, the side-push cylinder 52 intermittently pushes the tray, so that the chips on the tray fall into the cavity under slight vibration. After the chip is filled on the material tray, the conveying mechanism 2 acts to transfer the material tray to the discharging end. The lifting mechanism 3 lifts up and jacks up the material tray on the conveying mechanism 2, then slowly lifts up, and stops when the material tray contacts with the bottom of the material tray on the supporting claw 423. At this time, the exchanging cylinder 422 drives the supporting claw 423 to retract, the lifting mechanism 3 drives all the material trays to continuously rise to the height H, then the exchanging cylinder 422 drives the supporting claw 423 to extend out, at this time, the supporting claw 423 is located below the material tray at the bottommost layer, the lifting mechanism 3 descends to return to the initial position, and so on, and the stacking of the material trays is completed in sequence.
