[0032] Referring Figure 1 - Figure 2 as shown, the present solution provides a silicon wafer sorting mechanism, which includes:

[0033] A belt conveyor 1, the belt conveyor 1 extends in a first direction. The belt conveyor 1 includes a supporting portion 2 for supporting silicon wafers and a recessed portion 3 extending in a second direction. The recessed portion 3 can accommodate a main conveying mechanism for conveying silicon wafers, and the second direction is perpendicular to the first direction; and

[0034] A driving member 4, the driving member 4 can drive the belt conveyor 1 to move in a third direction perpendicular to the first direction and the second direction to raise the height of the supporting portion 2, so that the supporting portion 2 can lift the silicon wafers on the main conveying mechanism 16 and move the silicon wafers in the first direction.

[0035] The belt conveyor 1 can be used to support and convey silicon wafers, and it extends in the first direction, that is, its conveying direction is the first direction. In the installed and operating state, the first direction of the belt conveyor 1 can be a horizontal direction.

[0036] The second direction is perpendicular to the first direction and is the width direction of the belt conveyor 1.

[0037] The belt conveyor 1 includes multiple sections arranged in the first direction, that is, the supporting portion 2 and the recessed portion 3. The supporting portion 2 can support silicon wafers, and the recessed portion 3 is used to accommodate the main conveying mechanism 16. The main conveying mechanism 16 is a belt conveying mechanism or a similar mechanism for conveying silicon wafers.

[0038] The silicon wafer sorting mechanism of the present solution is used in conjunction with the main conveying mechanism 16. The silicon wafer sorting mechanism is installed so that the recessed portion accommodates the main conveying mechanism 16. The conveying direction of the main conveying mechanism 16 is the second direction. In addition, in the initial state, the height of the support portion 2 is less than the height of the main conveying mechanism 16, that is, the height of the silicon wafer conveyed by the main conveying mechanism 16 is higher than the height of the support portion 2, so that the silicon wafer on the main conveying mechanism 16 can be conveyed without being affected by the silicon wafer sorting mechanism. When it is necessary to sort the silicon wafers from the main conveying mechanism 16, the driving member can drive the belt conveyor 1 to move along the third direction, that is, move along the thickness direction of the silicon wafer on the main conveying mechanism 16, and the height of the support portion 2 increases, so that the silicon wafer on the main conveying mechanism 16 can be lifted up, so that the silicon wafer is separated from the main conveying mechanism 16, and the silicon wafer moves along the first direction on the support portion 2, that is, the silicon wafer is moved along the first direction so that the silicon wafer is separated from the main conveying mechanism 16, thereby realizing the sorting of the silicon wafer.

[0039] The silicon wafer sorting mechanism can be used to sort out unqualified silicon wafers (or other specific silicon wafers) from the main conveying mechanism 16. The silicon wafer sorting mechanism can be controlled by a control element, such as controlling the driving member 4 and the belt conveyor 1. When sorting is required, the driving member 4 is controlled to drive the belt conveyor 1 to rise. When the belt conveyor 1 lifts up the silicon wafer, the belt conveyor 1 is controlled to operate to move the silicon wafer away from the main conveying mechanism 16. After completing the sorting of the silicon wafers, the control element can control the belt conveyor 1 to stop running and control the driving member 4 to drive the belt conveyor 1 to descend. The belt conveyor 1 returns to a position where the support part 2 is lower than the main conveying mechanism 16 to allow the main conveying mechanism 16 to continue to transport the silicon wafers. Of course, the driving member 4 and the belt conveyor 1 can also be manually controlled by the operator.

[0040] In this solution, the silicon wafer sorting mechanism can be used in conjunction with the silicon wafer conveying mechanism to sort out the silicon wafers on the silicon wafer conveying mechanism. The sorting mechanism and the conveying mechanism cooperate compactly without increasing the conveying path of the silicon wafers, thereby improving the integration.

[0041] In some embodiments, the belt conveyor 1 includes two recessed portions 3 and three supporting portions 2 alternately arranged along the first direction. Figure 1 and Figure 2As shown, the supporting portions 2 and the recessed portions 3 are arranged alternately. The two recessed portions 3 can respectively accommodate two main conveying mechanisms 16, and these two main conveying mechanisms 16 can support the two side edges of the silicon wafer. One of the supporting portions 2 is located between the two recessed portions 3, and the other two supporting portions 2 are located on both sides of the two recessed portions 3. When the belt conveyor 1 is lifted as a whole under the action of the driving member 4, the three supporting portions 2 are all lifted, and the silicon wafer can be moved bidirectionally along the second direction as needed. The two supporting portions 2 located outside the recessed portions 3 can drive the silicon wafer to completely leave the main conveying mechanism 16. In some embodiments, one of the supporting portions 2 located outside the recessed portion 3 has a smaller dimension in the first direction, and the other supporting portion 2 located outside the recessed portion 3 has a larger dimension in the first direction. Correspondingly, the three supporting portions 2 are arranged such that the silicon wafer moves along the direction from the supporting portion 2 with a smaller dimension towards the supporting portion 2 with a larger dimension, and the supporting portion 2 with a larger dimension can carry the silicon wafer to completely leave the main conveying mechanism 16.

[0042] Among them, in some embodiments, the belt conveyor 1 includes a first belt 5 and a second belt 6 arranged at intervals along the second direction. The first belt 5 and the second belt 6 respectively include partial supporting portions 2 and partial recessed portions 3. The first belt 5 and the second belt 6 can have the same or similar structures, and the supporting portions 2 and the recessed portions 3 formed thereon are aligned along the second direction. The first belt 5 and the second belt 6 can respectively support the two edges of the silicon wafer.

[0043] In addition, in some embodiments, the belt conveyor 1 includes a first support plate 7 and a second support plate 8 arranged at intervals along the second direction, a first pulley 9 provided on the first support plate 7, and a second pulley 10 provided on the second support plate 8. The first belt 5 is supported on the first pulley 9, and the second belt 6 is supported on the second pulley 10. A plurality of first pulleys 9 on the first support plate 7 can support the first belt 5 so that the first belt 5 is formed in a form having partial supporting portions 2 and recessed portions 3. Similarly, a plurality of second pulleys 10 on the second support plate 8 can support the second belt 6 so that the second belt 6 is formed in a form having partial supporting portions 2 and recessed portions 3. In this solution, the belt is supported by the pulleys to extend along a specific path, thereby forming a specific structure, that is, a structural form having supporting portions 2 and recessed portions 3.

[0044] In addition, in some embodiments, the belt conveyor 1 includes a torque output member 11 disposed between the first support plate 7 and the second support plate 8. The torque output member 11 is drivingly connected to one of the first pulleys 9 and one of the second pulleys 10. The torque output member 11 can be an electric motor, a hydraulic motor, an engine, etc., which is drivingly connected to one of the first pulley 9 and one of the second pulleys 10 to drive the first belt 5 and the second belt 6 to run. Among them, the arrangement of the first pulley 9 and the second pulley 10 can be the same, that is, a plurality of first pulleys 9 and a plurality of second pulleys 10 are aligned in the second direction one by one, and the torque output member 11 can be drivingly connected to a set of aligned first pulley 9 and second pulley 10; of course, in other embodiments, the torque output member 11 can also be drivingly connected to the first pulley 9 and the second pulley 10 that are not opposite to each other.

[0045] In addition, in some embodiments, the belt conveyor 1 includes a support bottom plate 12, and the first support plate 7 and the second support plate 8 are connected to the top surface of the support bottom plate 12, and the driving member 4 is connected to the bottom surface of the support bottom plate 12. The support bottom plate 12 fixedly connects the first support plate 7 and the second support plate 8, and the driving member 4 is connected to the support bottom plate 12 to drive the structures such as the support bottom plate 12 to move up and down in the third direction.

[0046] Among them, in some embodiments, the driving member 4 can be an oil cylinder, a cylinder, an electric cylinder, etc., and is supported by a base 15.

[0047] In addition, in some embodiments, the wafer sorting mechanism further includes a discharge hopper 13 disposed on the side of the belt conveyor 1 along the first direction. After the belt conveyor 1 lifts and supports the wafers, the wafers can be conveyed to the discharge hopper 13 on the side to collect the wafers through the discharge hopper 13.

[0048] Among them, in some embodiments, the discharge hopper 13 extends obliquely. Refer to Figure 1 and Figure 2 As shown, the discharge hopper 13 includes a bottom plate, two side plates and an end plate, and its bottom plate extends obliquely, that is, forms an angle with the horizontal direction. When the wafers fall on the bottom plate, they can continue to slide under the action of gravity.

[0049] In addition, in some embodiments, the wafer sorting mechanism further includes a hopper seat 14 that supports the discharge hopper 13. The hopper seat 14 is disposed at the bottom of the discharge hopper 13 to support the discharge hopper 13 so that the discharge hopper 13 has a suitable height to receive the wafers from the belt conveyor 1.

[0050] On the other hand, refer to Figure 3As shown, this solution also provides a silicon wafer transportation and storage device, which includes the silicon wafer sorting mechanism of the above solution. The silicon wafer transportation and storage device may include a main transfer mechanism 16 and a silicon wafer sorting mechanism, and the silicon wafer sorting mechanism can sort out some specific silicon wafers on the main transfer mechanism 16. In addition, the silicon wafer transportation and storage device may further include a storage mechanism for temporarily storing silicon wafers.
