Description

Technical Field

[0001] The present application belongs to the technical field of silicon wafer production, and in particular relates to a packaging box flipping mechanism and a stacking and packaging device. Background Art

[0002] After the silicon wafers are inspected and sorted by the sorting machine, qualified wafers are collected and stacked in the material box one by one to form a stack, which is also stored in a packaging box for easy transportation. Due to the limited space in the packaging box, there is no extra space for the stack to be clamped by the clamping claws and sent into the packaging box. Therefore, the stack in the material box will be taken out by the clamping mechanism and sent to the pushing mechanism, which will send the stack into the packaging box at the packing station.

[0003] In order to save manpower, the packaging box is generally transported to the packing station via a conveyor line. After the packaging box is filled with stacked wafers, it is transported to the unloading station via a conveyor line. Since the stacked wafers are pushed into the packaging box from a horizontal direction, the opening of the packaging box needs to be open in the horizontal direction. In the process of transporting the packaging box from the packing station to the unloading station, the stacked wafers in the packaging box are easy to slide out from the opening of the packaging box, causing damage to the silicon wafers.

[0058] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0059] After the silicon wafers are inspected and sorted by the sorting machine, qualified wafers are collected and stacked in the material box one by one to form a stack, which is also stored in a packaging box for easy transportation. Due to the limited space in the packaging box, there is no extra space for the stack to be clamped by the clamping claws and sent into the packaging box. Therefore, the stack in the material box will be taken out by the clamping mechanism and sent to the pushing mechanism, which will send the stack into the packaging box at the packing station.

[0060] In order to save manpower, the packaging box is generally transported to the packing station via a conveyor line. After the packaging box is filled with stacked wafers, it is transported to the unloading station via a conveyor line. Since the stacked wafers are pushed into the packaging box from a horizontal direction, the opening of the packaging box needs to be open in the horizontal direction. In the process of transporting the packaging box from the packing station to the unloading station, the stacked wafers in the packaging box are easy to slide out from the opening of the packaging box, causing damage to the silicon wafers.
