Description

Technical Field

[0001] The utility model relates to the technical field of silicon wafer unloading, in particular to a DC material box for a sorting machine and a sorting machine. Background Art

[0002] At present, solar photovoltaic power generation has been increasing the demand for installation and production capacity in the entire photovoltaic industry due to its advantages of no emission, no noise, mature application technology, safety and reliability. In addition, in order to further reduce silicon costs and increase power generation efficiency, silicon wafers are gradually showing a trend of thinning, large size and rectangular wafers.

[0003] The silicon wafer sorter is an indispensable device for defect and performance detection of finished silicon wafers during the silicon wafer manufacturing process. With the demand for high photovoltaic installed capacity and silicon wafer expansion, the silicon wafer industry has put forward higher requirements on the capacity of the sorter, and the capacity of the high-speed sorter can reach 15,000 PCS / h. At the same time, as the thickness of silicon wafers continues to decrease, the rate of box fragments during the entire sorting process shows an increasing trend. The sorter is equipped with a DC material box facing the end of the main transmission line. Defective silicon wafers and missed silicon wafers will flow into the DC material box at a higher speed during the high-speed transmission of the main transmission line.

[0004] However, in this way, the silicon wafers are very likely to collide and break when flowing into the DC material box, and the collision rebound causes the silicon wafers to be uneven or even scattered on the ground, causing unnecessary loss of silicon wafers and increasing the process fragmentation rate.

[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Combine the following Figure 1 to Figure 2 The utility model describes a direct current material box for a sorting machine.

[0031] like Figure 1 to Figure 2As shown, the embodiment of the utility model provides a DC material box for a sorting machine, which is arranged at the end of the main transmission line of the sorting machine, and the DC material box includes a material box base and a buffer blowing device 1. Specifically, as Figure 1 As shown, the material box base is used to receive materials, such as miscellaneous silicon wafers or untested silicon wafers. The buffer blowing device 1 is arranged on the material box base, for example, a buffer air knife can be selected. The buffer blowing device 1 is used to form gas resistance to the inflowing material to buffer and decelerate the material. The buffer blowing device 1 is provided with an outlet 2 aligned with the end of the main transmission line. Specifically, as Figure 2 As shown, the air outlet 2 can be set as a strip hole. Of course, in other embodiments, the air outlet 2 can also be composed of multiple air outlet holes to achieve buffered blowing. In addition, the buffer air knife is also provided with at least one air inlet connected to the air outlet 2, and the air inlet is connected to the air source through the air inlet line 12.

[0032] With such arrangement, the buffering blowing device 1 is used to make the DC silicon wafers encounter gas resistance when flowing into the material box, so that the DC silicon wafers are decelerated and fall into the base of the material box, which plays a buffering and decelerating role, avoids the silicon wafers from being broken by severe impact, and the phenomenon of silicon wafers falling into the box unevenly or even scattering on the ground due to collision rebound, thereby reducing the fragmentation rate of DC silicon wafers.

[0033] In the embodiment of the utility model, the material box base includes a material box bottom plate 3 and a first baffle plate 4. Figure 1 As shown, the first baffle 4 is bent and connected to the bottom plate 3 of the material box to form an L-shaped DC material box, and the first baffle 4 is opposite to the end of the main transmission line. The buffer blowing device 1 is a pair, and the pair of buffer blowing devices 1 are respectively arranged at both ends of the first baffle 4. In this way, the DC silicon wafer can be prevented from being offset due to uneven force through the air blowing buffer on both sides, and the DC silicon wafer can be effectively prevented from colliding with the first baffle 4.

[0034] Further, in the embodiment of the present utility model, if Figure 2 As shown, a pair of buffer blowing devices 1 are arranged at an angle, and the air outlets 2 of the pair of buffer blowing devices 1 blow air in the direction of the middle position of the first baffle 4. With such an arrangement, the airflows on both sides tend to converge toward the middle, which is beneficial for the airflow to act on the DC silicon wafer, and reliably ensures that the DC silicon wafer slows down the inflow rate under the action of gas resistance to prevent collision and breakage.

[0035] As an optional embodiment of the present invention, the DC material box for the sorting machine also includes a guide rail 5, such as Figure 1As shown, the guide rail 5 is arranged along the transmission direction of the main transmission line, the material box base is slidably connected to the guide rail 5, and the material box base moves along the length direction of the guide rail 5. Specifically, the DC material box also includes a connecting frame 13 and a slider 14. The connecting frame 13 is installed on the lower surface of the material box bottom plate 3. Generally, the connecting frame 13 is located at the center of the material box bottom plate 3 to ensure stable support of the material box base. The slider 14 is installed at the lower end of the connecting frame 13, and the slider 14 is inserted into the guide groove of the guide rail 5, and the slider 14 can slide along the guide rail 5. Therefore, the sliding connection between the material box base and the guide rail 5 is realized through the connecting frame 13 and the slider 14.

[0036] With such arrangement, the magazine base can move forward and backward along the guide rail 5, so that the position can be adjusted according to the size of different silicon wafers, thereby expanding the adaptability of the DC magazine to silicon wafers of different sizes. Figure 1 As for the placement position of the DC material box used for the sorting machine shown in the figure, the direction indicated by the solid arrow in the figure is the transmission direction of the main transmission line, the length direction of the guide rail 5 and the front and back direction; the up and down directions in the figure are the up and down positions.

[0037] In an optional embodiment of the present invention, the DC material box for the sorting machine further includes a pair of second baffles 6 and a plurality of mounting portions 7. Figure 1 As shown, a pair of second baffles 6 are arranged along the transmission direction of the main transmission line. And a pair of second baffles 6 are respectively arranged at both ends of the material box bottom plate 3, so as to enclose together with the material box bottom plate 3 and the first baffle 4 to form a storage space for accommodating materials. At least two mounting parts 7 are respectively arranged at both ends of the material box bottom plate 3, and each mounting part 7 is spaced apart along the length direction of the material box bottom plate 3, and the second baffle 6 is detachably connected to the mounting part 7. Specifically, the mounting parts 7 on both sides are symmetrically distributed. It should be noted that the number of mounting parts 7 can be specifically determined according to actual design requirements.

[0038] In this way, a pair of second baffles 6 can be installed on the mounting parts 7 at appropriate positions according to the different sizes of DC silicon wafers, so as to adapt to the size of silicon wafers on the one hand, and regulate the falling track of silicon wafers on the other hand, improve the neatness of DC silicon wafers and avoid silicon wafers from falling. Figure 1 As for the placement position of the DC material box used in the sorting machine shown in the figure, the direction indicated by the hollow arrow in the figure is the length direction of the material box bottom plate 3.

[0039] Further, in the embodiment of the present utility model, if Figure 1 As shown, the second baffle 6 is slidably connected to the mounting portion 7, and the second baffle 6 moves along the transmission direction of the main transmission line. In this way, the second baffle 6 can move forward and backward along the transmission direction of the main transmission line, so that the second baffle 6 can be moved forward to extend out of the material box base to serve as a guide rail to assist the silicon wafer to fall into the box.

[0040] In a specific embodiment of the present invention, one of the second baffle plate 6 and the mounting portion 7 is provided with a clamping portion 8, and the other is provided with a clamping slot 9, and the clamping portion 8 is clamped in the clamping slot 9. That is, the second baffle plate 6 is provided with a clamping portion 8, and the mounting portion 7 is provided with a clamping slot 9; or, the second baffle plate 6 is provided with a clamping slot 9, and the mounting portion 7 is provided with a clamping portion 8. For example, Figure 1 As shown, the lower end of the second baffle 6 is provided with a clamping portion 8, and the mounting portion 7 is provided with a matching clamping slot 9. Thus, a clamping structure is formed, so that the second baffle 6 and the bottom plate 3 of the material box are connected as one, which is convenient to operate and easy to disassemble and assemble. Specifically, the clamping slot 9 can be set as an inverted T-shaped slot, and the clamping portion 8 is set as a matching T-shaped clamping portion, so that the two are reliably and firmly connected. In addition, the clamping portion 8 can be slidably set in the clamping slot 9. Of course, in other embodiments, the shapes of the clamping slot 9 and the clamping portion 8 include but are not limited to T-shaped structures.

[0041] As an optional embodiment of the present invention, a notch 10 for taking out materials is provided at the end of the material box bottom plate 3. Specifically, notches 10 are provided at both ends of the material box bottom plate 3. Such a configuration facilitates taking out materials. In addition, when taking out materials, the second baffle 6 can be moved backward along the transmission direction of the main transmission line so as to cooperate with the opening at the bottom of the box to facilitate receiving materials.

[0042] In an optional embodiment of the present utility model, as Figure 2 As shown, a buffer pad 11 is provided on the side of the first baffle plate 4 that contacts the material. Figure 1 As shown, a pair of second baffles 6 are provided with a buffer plate 11 on one side in contact with the material. Specifically, the buffer plate 11 can be made of polytetrafluoroethylene. Thus, it can provide a buffering and protective effect on the silicon wafer, preventing the silicon wafer from collapsing and breaking. Of course, in other embodiments, the material of the buffer plate 11 includes but is not limited to polytetrafluoroethylene.

[0043] In summary, the embodiment of the utility model provides a DC material box for a sorting machine, which can be set at the end of the main transmission line of the sorting machine to receive DC silicon wafers. Specifically, the buffering air blowing device 1 can be used to slow down the silicon wafers and then fall into the box to prevent serious collision with the material box baffle. In addition, with the overall forward and backward movement of the material box base and the movable second baffles 6 on both sides of the material box, it can not only adapt to silicon wafers of different specifications, but also regulate the falling posture of the silicon wafers to avoid uneven falling of the box or even scattering on the ground. At the same time, with the opening of the bottom plate 3 of the material box, it is convenient for production and material collection. Specifically, if Figure 1As shown, when receiving smaller silicon wafers, the base of the material box can be adjusted forward, close to the end of the main transmission line, and the second baffle 6 is adapted to the silicon wafer to be installed in the inner slot 9 and is completely aligned with the edge of the bottom plate 3 of the material box. When receiving larger silicon wafers, the base of the material box can be adjusted backward, away from the end of the main transmission line, and the second baffle 6 is adapted to the silicon wafer to be installed in the outer slot 9 and extends forward to serve as a guide to assist the silicon wafer to fall into the box. When taking out the material, the second baffles 6 on both sides can move backward to cooperate with the notch 10 of the bottom plate 3 of the material box to facilitate the silicon wafer receiving.

[0044] The sorting machine provided by the present invention is described below. The sorting machine described below and the DC material box for the sorting machine described above can refer to each other.

[0045] The utility model also provides a sorting machine, including a DC material box for the sorting machine as described in the above embodiments. With such a configuration, the DC silicon wafers are subjected to gas resistance when flowing into the material box through the buffering air blowing device 1, so that the DC silicon wafers are decelerated and fall into the base of the material box, which plays a buffering and decelerating role, avoids the silicon wafers from being severely impacted and broken, and avoids the phenomenon that the silicon wafers fall unevenly into the box or even scatter on the ground due to collision rebound, thereby reducing the fragmentation rate of the DC silicon wafers. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the DC material box for the sorting machine described above, so it will not be repeated here.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
