[0051] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that the present invention's explanation of the sorting device of the present invention by the cooperation between the incoming material detection mechanism and the jacking mechanism to achieve the screening of the material head and the sample is only a preferred embodiment, and does not limit the scope of protection of the sorting device. For example, the present invention can also adopt the method of directly pushing the material into the aggregate box when the incoming material detection mechanism detects that the material is a sample, so as to achieve the sorting of the material and the material head.

[0052] It should be understood that the terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, as used herein, the singular forms "a," "an," and "including" may also be intended to include the plural forms. The terms "comprising," "including," and "having" are inclusive and, therefore, specify the presence of the stated features, elements, and / or components, but do not preclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0053] Although the terms first, second, etc. may be used herein to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply a sequence or order when used herein. In addition, in the description of the present invention, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances.

[0054] For ease of description, spatial relative terms can be used in the text to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "front", "back", "center", "inside", "longitudinal", "lateral", "side", "vertical", "outside", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation other than the orientation depicted in the figure. For example, if the mechanism in the figure flips, the element described as "below other elements or features" or "below other elements or features" will then be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include both upper and lower orientations. The mechanism can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0055] Silicon rods are cut into desired thicknesses by a cutter before being exported. Before being formed into wafers, the ends of the rods must be cut off before being sliced ​​into wafers by a cutter. The cut ends and wafers are then transferred to a conveyor belt. Manual sorting is often performed during the conveyor belt's transport, reducing sorting and collection efficiency.

[0056] Based on this, the utility model provides a sorting device, which detects the incoming materials through an incoming material detection mechanism, and the material heads after detection continue to be transmitted. The sample pieces after detection are lifted up by the sample lifting mechanism, thereby realizing the sorting of the material heads and the sample pieces, making it convenient to collect the material heads and the sample pieces separately.

[0057] The specific embodiments of the present invention are described in detail below in conjunction with the sorting device of the first aspect of the present invention.

[0058] It should be noted that the sorting device of the first aspect of the present invention is only a preferred embodiment of the present invention. The sorting device of the present invention can adopt the sorting device of the first aspect of the present invention or other structures. For the convenience of explanation, the sorting device of the first aspect of the present invention is explained in detail below.

[0059] Combine Figures 1 to 3As shown, this embodiment discloses a sorting device, including a first frame 11, a conveyor mechanism 12, an incoming material detection mechanism 13, and a sample lifting mechanism 15. The conveyor mechanism 12 is arranged on the first frame 11, with one side of the conveyor mechanism 12 being the feed end, and the other side of the conveyor mechanism 12 being the discharge end. The incoming material detection mechanism 13 is arranged on the first frame 11 near the feed end of the conveyor mechanism 12, and the incoming material detection mechanism 13 is suitable for identifying materials entering the conveyor mechanism 12. The sample lifting mechanism 15 is arranged below the middle position of the conveyor mechanism 12 and is staggered with the conveyor mechanism 12.

[0060] In the above-mentioned sorting device, when the incoming material detection mechanism 13 detects that the material is a material head, the conveying mechanism 12 transfers the material head to the discharge end, and then the material head is collected by the unloading conveying mechanism 4 connected to the discharge end. When the incoming material detection mechanism 13 detects that the material is a sample, the sample lifting mechanism 15 lifts the sample to separate the sample from the conveying mechanism 12, making it easier to screen the sample from the conveying mechanism 12. In this embodiment, the incoming material detection mechanism 13 and the sample lifting mechanism 15 cooperate with each other to jointly realize the screening of material heads and samples, and cooperate with the sample collection mechanism 2 to realize the collection of samples, and cooperate with the unloading conveying mechanism 4 to realize the temporary storage and collection of samples. Compared with the manual sorting method of material heads and samples, this embodiment can quickly sort material heads and samples, improve the sorting efficiency, and further improve the collection efficiency of material heads and samples.

[0061] In some embodiments, the incoming material detection mechanism 13 includes a bracket 131, a signal transmitter 132, and a signal receiver 133. The bracket 131 is mounted on the first frame 11 near the feed end of the conveyor mechanism 12. The signal transmitter 132 is mounted on one side wall of the bracket 131. The signal receiver 133 is mounted on the other side wall of the bracket 131, facing the signal transmitter 132. The signal receiver 133 receives the signal from the signal transmitter 132, and the signal transmitter 132 and the signal receiver 133 form a beaming switch. The signal receiver 133 is activated when the signal transmitter 132 receives incoming material.

[0062] The signal transmitter 132 and signal receiver 133 are positioned above the height of the blanks and below the height of the slugs. When a sample arrives, its height is lower than the height of the signal transmitter 132 and signal receiver 133, allowing the signal receiver 133 to detect the signal and identify it as a sample. When a slug arrives, the signal to the signal transmitter 132 is blocked because the slug is higher than the height of the signal transmitter 132 and signal receiver 133, thus identifying it as a slug.

[0063] In some embodiments, the conveying mechanism 12 includes a driving shaft, a driven shaft, a drive motor 126, a linkage assembly, a first rotating wheel 122, a second rotating wheel 123, and a first conveyor belt 121. The driving shaft is connected to the drive motor 126 via a linkage assembly. Two first rotating wheels 122 are coaxially connected to the driving shaft, and two second rotating wheels 123 are coaxially connected to the driven shaft. A first conveyor belt 121 is respectively sleeved between the two first rotating wheels 122 and the two second rotating wheels 123, with a gap between the two first conveyor belts 121. The linkage assembly includes a third rotating wheel 124, a fourth rotating wheel 125, and a transmission chain 127. The third rotating wheel 124 is coaxially connected to the first rotating wheel 122, and the fourth rotating wheel 125 is rotatably mounted on the first frame 11. A transmission chain 127 is sleeved between the third rotating wheel 124 and the fourth rotating wheel 125, and the fourth rotating wheel 125 is connected to the output shaft of the drive motor 126.

[0064] In some embodiments, a sample blocking mechanism 14 is further provided between the two first conveyor belts 121. When the incoming material detection mechanism 13 detects that the material is a sample, the telescopic end of the sample blocking mechanism 14 extends out of the first conveyor belt 121 to block the sample, thereby slowing down the conveying speed of the sample, so that the position of the sample after being lifted by the sample lifting mechanism 15 remains consistent, thereby ensuring the accuracy of the sample feeding.

[0065] Combine Figure 2 As shown, the sample blocking mechanism 14 includes a first cylinder 141, a first connecting plate 142, and a sample blocking rod 143. The first cylinder 141 is retractable in the vertical direction. The piston rod end of the first cylinder 141 is connected to the first connecting plate 142. At least one sample blocking rod 143 is provided and positioned on the first connecting plate 142. When the incoming material detection mechanism 13 detects that the material is a sample, the piston rod of the first cylinder 141 extends, driving the sample blocking rod 143 to extend from the first conveyor belt 121, blocking the sample so that the sample lifting mechanism 15 can lift the sample.

[0066] In some embodiments, the sample lifting mechanism 15 is disposed between the two first conveyor belts 121. Figure 3 As shown, the sample lifting mechanism 15 includes a second cylinder 151, a second connecting plate 152, a lifting rod 153, and a top sheet pad 154. The piston rod of the second cylinder 151 is connected to the second connecting plate 152, and the second connecting plate 152 is connected to a positioning block 155 positioned on the first frame 11 via a telescopic rod 156. At least one lifting rod 153 is provided at the top of the second connecting plate 152, and a top sheet pad 154 is provided on the lifting rod 153. In this embodiment, the top sheet pad 154 can be configured as an elastic top sheet pad so that when it contacts the sample, it can reduce the impact on the sample and provide a buffering and protective effect on the sample.

[0067] The specific embodiments of the present invention are described in detail below in conjunction with the blanking system of the second aspect of the present invention.

[0068] It should be noted that the blanking system of the second aspect of the present invention is only a preferred embodiment of the present invention. The blanking system of the present invention can adopt the blanking system of the second aspect of the present invention or other structures. For the convenience of explanation, the blanking system of the second aspect of the present invention is explained in detail below.

[0069] Combine Figures 1 to 7 As shown, this embodiment discloses a material unloading system, comprising a sorting device 1, a sample collection mechanism 2, and a material unloading conveyor mechanism 4. The sample collection mechanism 2 is disposed on the side of the sample lifting mechanism 15 and is adapted to collect samples lifted by the sample lifting mechanism 15. The material unloading conveyor mechanism 4 is connected to the discharge end of the conveyor mechanism 12 and is provided with a material holding area 42, which is adapted to collect the material head.

[0070] The above-mentioned unloading system screens out the material heads and samples through the sample collecting mechanism 2. The sample collecting mechanism 2 can collect the samples lifted by the sample lifting mechanism 15. The unloading conveying mechanism 4 can take over the material heads that are not lifted by the sample lifting mechanism 15, thereby realizing the screening and collection of the material heads and samples.

[0071] It should be noted that the material heads in this embodiment are the head materials obtained by cutting the head of the silicon rod or the tail materials obtained by cutting the tail of the silicon rod, and the sample pieces are silicon wafers.

[0072] In some embodiments, the sample collection mechanism 2 includes a sample collection structure 21, a paddle structure 22, and a lifting structure 23. The paddle structure 22 and the lifting structure 23 are both disposed on a second frame 25. The sample collection structure 21 is disposed on one side of the conveying mechanism 12, and a feed port 213 is disposed on a side wall of the sample collection structure 21 opposite to the conveying mechanism 12. The paddle structure 22 and the sample collection structure 21 are disposed on both sides of the conveying mechanism 12, respectively. The paddle structure 22 is adapted to push the samples on the conveying mechanism 12 into the sample collection structure 21. The telescopic end of the lifting structure 23 is connected to the bottom wall of the sample collection structure 21. When the telescopic end of the lifting structure 23 moves, it drives the sample collection structure 21 to rise and fall, thereby changing the collection position of the sample collection structure 21.

[0073] The sample collection mechanism 2 described above uses the conveying mechanism 12 to transport the samples to the position to be shifted, and uses the shifting mechanism 22 to shift the samples on the conveying mechanism 12 into the cavity of the sample collection structure 21. While the sample collection structure 21 is collecting the samples, the lifting mechanism 23 controls the lifting of the sample collection structure 21 so that the area within the sample collection structure 21 that can hold the samples always corresponds to the position of the shifting mechanism 22, thereby continuously collecting the samples. Compared with the current method of manually collecting samples, this embodiment automatically collects the samples throughout the entire process, greatly improving collection efficiency and reducing manual labor.

[0074] The paddle structure 22 includes a paddle claw 221, a paddle drive assembly 223, and a driven rod 224. The fixed end of the paddle drive assembly 223 is mounted on the second frame 25, and the telescopic end of the paddle drive assembly 223 is connected to the paddle claw 221. The telescopic direction of the paddle drive assembly 223 corresponds to the feeding direction. One end of the driven rod 224 is connected to the paddle claw 221, and the other end of the driven rod 224 is slidably mounted on the second frame 25. The driven rod 224 is parallel to the telescopic direction of the paddle drive assembly 223. In this embodiment, when the paddle drive assembly 223 retracts, it drives the paddle claw 221 to move in the feeding direction, pushing the sample into the feed port 213 of the lifting structure 23, thereby feeding the sample. The paddle drive assembly 223 in this embodiment is a paddle cylinder, and the paddle cylinder and the driven rod 224 are respectively located on either side of the sample collection structure. However, the paddle drive assembly 223 is not limited to the paddle cylinder, and other telescopic drive assemblies can also be used.

[0075] The driven rod 224 is slidably disposed on a driven rod positioning seat 225 , and the driven rod positioning seat 225 is disposed on the second frame 25 .

[0076] A paddle pad 222 is provided on the side wall of the paddle claw 221 corresponding to the feed port 213 , and the paddle pad 222 plays a buffering and protective role for the sample.

[0077] Furthermore, a groove is provided on the side of the paddle pad 222 near the feed inlet 213. The groove gradually expands from the side away from the feed inlet 213 to the side near the feed inlet 213, thereby being able to adapt to samples of different diameters. The paddle pad 222 is provided in a V-shape, but is not limited to a V-shape and can also be provided in other shapes.

[0078] The lifting structure 23 includes a lifting cylinder 231 and a guide assembly 232. The telescopic end of the lifting cylinder 231 is connected to the sample collection structure 21, while the fixed end of the lifting cylinder 231 is mounted on the second frame 25. The guide assembly 232 is positioned between the sample collection structure 21 and the second frame 25 and serves as a guide for the lifting of the sample collection structure. When the piston rod of the lifting cylinder 231 is extended, the sample collection structure 21 is lifted; when the piston rod of the lifting cylinder 231 is shortened, the sample collection structure 21 is lowered.

[0079] The lifting cylinder 231 is a stroke-adjustable cylinder. The lifting structure 23 also includes a lifting limiter 24, which is adapted to limit the lifting stroke of the lifting cylinder 231 to ensure that after each lifting of the lifting cylinder 231, a storage cavity on the sample collection structure 21 corresponds to the position of the pick claw 221.

[0080] The lifting and limiting structure 24 includes a segmented plate 244, a positioning rod 243 and a segmented driving assembly 241. The top of the segmented plate 244 is connected to the sample collecting structure 21. The segmented plate 244 is set on the sample collecting structure 21, and the segmented plate 244 is provided with a segmented hole 246. Figure 6 As shown, segmented hole 246 comprises transverse hole segments 2461 and vertical hole segments 2462 that are alternately arranged in a reciprocating manner. Positioning rod 243 is perpendicular to segmented hole 246 and is slidably assembled within segmented hole 246. The telescopic end of segmented drive assembly 241 is connected to positioning rod 243 and is adapted to drive positioning rod 243 to extend and retract laterally along transverse hole segment 2461.

[0081] Furthermore, the guide assembly 232 includes a fixed portion 2321 and a connecting rod portion 2322. The fixed portion 2321 is fixedly mounted on the sample collection structure 21, and the segmented plate 244 is fixedly mounted on the fixed portion 2321. The connecting rod portion 2322 is vertically mounted on the second frame 25. The fixed portion 2321 is slidably mounted on the connecting rod portion 2322, and can be raised and lowered on the connecting rod 45.

[0082] Further, combined with Figure 7 As shown, the lifting and limiting structure 24 also includes positioning guide rods 242. Two positioning guide rods 242 are provided, one end of each of which is connected to the two ends of the positioning rod 243 extending out of the segmented hole 246, and one end of each of the positioning guide rods 242 is connected to the frame. The positioning guide rods 242 provided in this embodiment can serve as auxiliary guides, preventing the positioning rod 243 from slipping out of the segmented hole 246 during the sliding process.

[0083] The sample collection structure 21 is a sample collection box. The sample collection box includes a box body 211, which is internally provided with a plurality of partitions 212. Each partition 212 divides the sample collection box into a plurality of storage chambers spaced apart from each other. The transverse hole section 2461 is parallel to the partition 212. Each vertical hole section 2462 corresponds to a storage chamber, and the height of the vertical hole section 2462 is the same as the height of the corresponding storage chamber. Therefore, each time the lifting cylinder 231 drives the sample collection box to rise to the same height as the vertical hole section 2462, the lifting cylinder 231 drives the storage chamber to be stored in the sample collection box to a position corresponding to the pick claw 221, ensuring the accuracy of the sample feeding.

[0084] In this embodiment, the transverse hole section 2461 and the vertical hole section 2462 are arranged alternately and reciprocally. Therefore, before the lifting cylinder 231 needs to drive the sample collecting structure 21 to rise, the segmented driving assembly 241 needs to drive the positioning rod 243 to move horizontally to the vertical hole section 2462, and then the lifting cylinder 231 drives the sample collecting structure 21 to rise. When the lifting cylinder 231 drives the sample collecting structure 21 and the segmented plate 244 to rise to a position abutting the positioning rod 243, the positioning rod 243 is limited by the bottom end position of the vertical hole section 2462, and the piston rod of the lifting cylinder 231 also stops rising. At this time, a certain storage cavity on the sample collecting structure 21 is directly opposite the position of the pick claw 221. After the paddle claw 221 has moved the sample into the feed port 213 of the sample collection structure 21, when switching to the next storage chamber, the segmented drive assembly 241 needs to drive the positioning rod 243 to move horizontally to the inlet end of the next vertical hole section 2462, thereby performing a reciprocating motion. The above-mentioned lifting limit structure 24 can effectively control the lifting position of the lifting cylinder 231, making the lifting position of the lifting cylinder 231 and the upward position of each storage chamber more accurate, ensuring that each time the lifting cylinder 231 lifts the sample collection structure 21, the previous storage chamber of the sample collection structure 21 corresponds to the position of the paddle claw 221, thereby ensuring that the paddle claw 221 can accurately move the sample into the storage chamber of the sample collection structure 21.

[0085] In some embodiments, the unloading conveyor mechanism 4 is connected to the discharge end of the conveyor mechanism 12 via the unloading transition mechanism 3. The unloading transition mechanism 3 and the conveyor mechanism 12 operate synchronously, while the unloading transition mechanism 3 and the unloading conveyor mechanism 4 operate independently. In this embodiment, the unloading transition mechanism 3 serves to transfer the material ends. Because the unloading transition mechanism 3 and the unloading conveyor mechanism 4 operate independently, the unloading conveyor mechanism 4 does not need to move when the conveyor mechanism 12 moves. The unloading conveyor mechanism 4 can collect and temporarily store the material ends.

[0086] The unloading transition mechanism 3 includes a second conveyor belt 31, a third conveyor belt 32, a first rotating shaft and a second rotating shaft. The first rotating shaft and the second rotating shaft are respectively rotatably arranged on the frame of the unloading conveying mechanism 4. The second conveyor belt 31 is sleeved between the first rotating shaft and the driving shaft of the conveying mechanism 12. Two third conveyor belts 32 are sleeved on the first rotating shaft and the second rotating shaft. The second conveyor belt 31 is located between the two third conveyor belts 32.

[0087] In some embodiments, the head and tail ends of the unloading conveyor mechanism 4 are respectively provided with proximity switches 41. When the two proximity switches 41 detect the material head signal at the same time, it indicates that the material head in the waiting area of ​​the unloading conveyor mechanism 4 is full and the material head can be unloaded, and the unloading conveyor mechanism 4 performs the unloading action.

[0088] The specific working process of the above-mentioned blanking system is as follows:

[0089] The material enters the feeding end position of the conveying mechanism 12, and the conveying mechanism 12 transports the material to the position of the incoming material detection mechanism 13, and the signal transmitter 132 sends a signal.

[0090] When conveyor mechanism 12 is transporting a material head, the material head blocks the signal from signal transmitter 132, preventing signal reception by signal receiver 133. Signal receiver 133 then feeds the detection signal back to the controller in real time, which determines that the material is now a material head. The controller issues a continue conveyance command, and conveyor mechanism 12 continues to transport the material head to unloading transition mechanism 3, where it then enters the holding area of ​​the unloading conveyor mechanism and stops to temporarily store the material head. Meanwhile, the feed end of conveyor mechanism 12 continues to feed material, preventing operational stagnation.

[0091] When the conveyor mechanism 12 is conveying a sample, the signal emitted by the signal transmitter 132 is transmitted from above the sample to the signal receiver 133. The signal receiver 133 feeds the detection signal back to the controller in real time, and the controller determines that the material is a sample. The controller issues a material blocking command, controlling the piston rod of the first cylinder 141 to extend. The first cylinder 141 drives the sample blocking rod 143 upward to block the sample. The controller then issues a material raising command, controlling the piston rod of the second cylinder 151 to extend, lifting the sample, and the conveyor mechanism 12 no longer conveys the sample. The controller then issues a sample collecting command, controlling the paddle drive assembly 223 of the paddle mechanism 22 to operate, and the paddle claw 221 paddles the sample into the storage chamber of the sample collection mechanism 21, thereby collecting the sample. After completing one sample collection, the controller sends a lifting command to the lifting cylinder 231, which controls the sample collection structure 21 to rise to the height of one storage chamber, so that the next storage chamber is directly opposite the pick claw 221, so that the next sample can be collected. When the sample collection structure 21 is full of samples, the samples are unloaded.
