[0054] The stacking device provided in the embodiment of the present application can be suitable for handling and sorting silicon wafers and battery cells. For example, the first material is silicon wafers, and the second material is a protective sheet, and the protective sheet can be, for example, pearl cotton. The silicon wafers and pearl cotton are alternately stacked to protect the silicon wafers.

[0055] In the stacking device 1 provided in the embodiment of the present application, the stacking mechanism 11 can transport silicon wafers along the first direction under the driving force of the transport shaft 10; the suction cup mechanism 12 can transport pearl cotton along the first direction under the driving force of the transport shaft 10. For example, the stacking device 1 provided in the embodiment of the present application also includes an auxiliary material bin 15, which is used to feed pearl cotton, and the suction cup mechanism 12 takes pearl cotton from the auxiliary material bin 15. The intermediate transfer platform 13 is used to temporarily store silicon wafers or pearl cotton; for example, the stacking device 1 provided in the embodiment of the present application also includes a transport mechanism 16, which can transport silicon wafers from the previous process to the intermediate transfer platform 13; for example, the silicon wafers are packaged silicon wafers after bagging and folding in the previous process; a blowing mechanism is provided at the intermediate transfer platform 13, which can keep the bag edge of the packaging bag containing silicon wafers folded upward to facilitate the stacking mechanism 11 to take the packaged silicon wafers.

[0056] By using the stacking equipment provided in the embodiment of the present application, the process of picking up and transporting the first material and the second material is a fully automatic process, without the need for human intervention, with a high degree of automation and work efficiency, which is beneficial to reducing production costs; and the supporting positioning platform 14 can position the first material and the second material, thereby improving the positioning accuracy of the placement of the first material and the second material.

[0057] Reference Figure 1b to Figure 1i As shown, in one embodiment, the stacking mechanism 11 includes a pressing assembly 111 and a supporting assembly 112, and the pressing assembly 111 and the supporting assembly 112 are used to cooperate with each other to clamp the first material; the pressing assembly 111 is used to abut against one surface of the first material along the second direction, and the supporting assembly 112 is used to abut against another surface of the first material along the second direction.

[0058] In this specific example, the pressing assembly 111 and the supporting assembly 112 cooperate with each other to clamp the silicon wafer from two opposite surfaces of the silicon wafer, which can not only stably take the silicon wafer but also avoid damage to the silicon wafer. The second direction corresponds to the thickness direction of the silicon wafer.

[0059] Reference Figure 1b to Figure 1i As shown, in one embodiment, the pressing assembly 111 includes a pressing plate 1111, a pressing drive 1112 and a pressing adapter. The pressing drive 1112 can provide a driving force for movement along the second direction. The pressing drive 1112 is connected to the pressing plate 1111 through the pressing adapter.

[0060] In this specific example, the pressing driving member 1112 can drive the pressing plate 1111 to move along the second direction through the pressing adapter, and the pressing assembly 111 clamps the silicon wafer when the pressing plate 1111 moves along the second direction toward the supporting assembly 112; and releases the silicon wafer when the pressing plate 1111 moves along the second direction away from the supporting assembly 112. For example, the pressing driving member 1112 is a cylinder.

[0061] Reference Figure 1b to Figure 1i As shown, in one embodiment, the pressing adapter includes an adapter plate 1113, an adapter 1114 and an adapter guide rod 1115, the adapter 1114 is connected to the pressing drive 1112, and the adapter 1114 is also connected to the adapter plate 1113, one end of the adapter guide rod 1115 is connected to the adapter plate 1113, and the other end is connected to the pressing plate 1111.

[0062] In this specific example, the adapter plate 1113, the adapter 1114 and the adapter guide rod 1115 cooperate with each other to transmit the driving force of the pressing drive member 1112 to the pressing plate 1111. For example, the pressing drive member 1112 is a cylinder, and the extended end of the piston rod of the cylinder is connected to the adapter 1114, and the adapter 1114 is also connected to the adapter plate 1113, so that the adapter 1114 transmits the driving force of the cylinder to the adapter plate 1113; the adapter guide rod 1115 is connected between the adapter plate 1113 and the pressing plate 1111, so as to realize the transmission of the driving force of the cylinder from the adapter 1114 to the adapter plate 1113, and then to the adapter guide rod 1115 and finally to the pressing plate 1111.

[0063] Reference Figure 1b to Figure 1i As shown, in one embodiment, the number of the transfer guide rods 1115 is four, the four transfer guide rods 1115 are distributed at the edge positions of the transfer plate 1113, the four transfer guide rods 1115 are arranged around the adapter 1114, and the adapter 1114 is located in the middle of the four transfer guide rods 1115.

[0064] In this specific example, four transfer guide rods 1115 are arranged between the adapter plate 1113 and the pressing plate 1111; for example, the adapter plate 1113 is roughly rectangular, and the four transfer guide rods 1115 are distributed at the four vertex positions of the adapter plate 1113, which helps to evenly and stably transmit the driving force of the pressing drive member 1112 to the pressing plate 1111. In addition, the four transfer guide rods 1115 are arranged around the adapter 1114, and the adapter 1114 is located in the middle of the area enclosed by the four transfer guide rods 1115 at the adapter plate 1113, which can ensure the stability of the transfer plate 1113 in transmitting the driving force of the pressing drive member 1112 and prevent the adapter plate 1113 from being deflected.

[0065] Furthermore, the pressing plate 1111 is also roughly rectangular, and four transfer guide rods 1115 are distributed at the four vertex positions of the pressing plate 1111.

[0066] In other embodiments, if the pressing plate 1111 and / or the adapter plate 1113 are in other shapes, the adapter guide rods 1115 may have other configurations and quantities as long as the stability of the driving force is ensured.

[0067] Reference Figure 1b to Figure 1i As shown, in one embodiment, the adapter plate 1113 is provided with a notch portion 1110, and the adapter 1114 includes a first baffle 1116, a second baffle 1117 and a connecting rod 1118, the first baffle 1116 and the second baffle 1117 are arranged opposite to each other, and the connecting rod 1118 is connected between the first baffle 1116 and the second baffle 1117;

[0068] The connecting rod 1118 is snap-connected with the adapter plate 1113 at the notch 1110 , the first blocking piece 1116 abuts against the surface of the adapter plate 1113 facing the pressing plate 1111 , and the second blocking piece 1117 abuts against the surface of the adapter plate 1113 facing away from the pressing plate 1111 .

[0069] In this specific example, the connecting rod 1118 of the adapter 1114 is connected to the adapter plate 1113 at the notch 1110, so that the adapter 1114 and the adapter plate 1113 are tightly and reliably connected, and the assembly of the two is relatively convenient. In addition, the adapter plate 1113 is connected between the first baffle 1116 and the second baffle 1117, and the adapter plate 1113 abuts against the first baffle 1116 and the second baffle 1117, so that the adapter plate 1113 and the adapter 1114 can be prevented from being loose.

[0070] Furthermore, the pressing assembly 111 further includes four linear bearings 1119, which are connected one-to-one with the transfer guide rod 1115. The linear bearings 1119 can position the transfer guide rod 1115 in the second direction to ensure that the transfer guide rod 1115 does not deflect when moving in the second direction. It can be understood that the transfer guide rod 1115 is extended along the second direction.

[0071] Reference Figure 1b to Figure 1i As shown, in one embodiment, the supporting assembly 112 includes two supporting sub-components, and the supporting sub-components include a supporting plate 1121, a first supporting adapter 1122, a second supporting adapter 1123, a first supporting driving component 1124, and a second supporting driving component 1125; the supporting plates 1121 included in the two supporting sub-components are arranged opposite to each other;

[0072] The first supporting driving member 1124 is connected to the first supporting adapter 1122, the second supporting driving member 1125 is installed on the first supporting adapter 1122, and the second supporting driving member 1125 is connected to the supporting plate 1121 through the second supporting adapter 1123;

[0073] The first supporting driving member 1124 can drive the corresponding supporting plate 1121 to move so that the supporting plates 1121 included in the two supporting sub-members are closer to each other or farther away from each other;

[0074] The second supporting driving member 1125 can drive the corresponding supporting plate 1121 to move along the second direction.

[0075] In this specific example, the supporting plates 1121 included in the two supporting sub-components support the bottom of the first material from both sides of the first material, thereby clamping the first material with the pressing plate 1111. Before the clamping operation begins, the distance between the two supporting plates 1121 is large, and the two supporting plates 1121 are far away from the pressing plate 1111 along the second direction. When performing the clamping operation, the two support plates 1121 are moved closer to each other under the driving force of their respective first support driving members 1124 to be located at the bottom of the first material, and the distance between the two support plates 1121 is reduced; then the support plates 1121 are lifted in the second direction (i.e., moved toward the pressing plate 1111) under the driving force of their respective second support driving members 1125 to support the bottom of the first material, and at the same time, the pressing plate 1111 is pressed down in the second direction (i.e., moved toward the support plate 1121) under the driving force of the pressing driving member 1112, so that the pressing plate 1111 and the support plate 1121 cooperate with each other to clamp the first material.

[0076] Optionally, the first supporting driving member 1124 and the second supporting driving member 1125 are both cylinders; optionally, the supporting plate 1121 contained in each supporting sub-member may be an integral plate-like structure, or the supporting plate 1121 contained in each supporting sub-member may include more than two separately arranged sub-plates; optionally, the first supporting adapter 1122 and the second supporting adapter 1123 are both adapter plates, and the shapes and specific structures of the first supporting adapter 1122 and the second supporting adapter 1123 may be flexibly set according to actual conditions.

[0077] Reference Figure 1b to Figure 1i As shown, in one embodiment, the stacking mechanism 11 further includes a side pressure assembly 113, and the side pressure assembly 113 is disposed adjacent to the supporting assembly 112, and the side pressure assembly 113 is configured to abut against the side of the first material.

[0078] In this specific example, the side pressure assembly 113 can assist the pressing assembly 111 and the supporting assembly 112 in clamping the first material; for example, the first material is a package of silicon wafers. Before the clamping operation begins, the side pressure assembly 113 first clamps the package of silicon wafers from the side. On the one hand, it can fix the bag opening of the package of silicon wafers and prevent the bag opening from loosening. On the other hand, the side pressure assembly 113 clamps the package of silicon wafers from the side and slightly lifts it up along the second direction, so that the two supporting plates 1121 can enter the bottom of the package of silicon wafers to support them. In the process of transporting the package of silicon wafers, the side pressure assembly 113 can maintain the clamping state or slightly loosen it. When it is necessary to release the packaged silicon wafers, the side pressure assembly 113 first clamps the packaged silicon wafers from the side, and then the two supporting plates 1121 move away from the pressing plate 1111 along the second direction under the driving force of their respective second supporting driving members 1125 to detach from the bottom of the packaged silicon wafers, and then the two supporting plates 1121 move away from each other under the driving force of their respective first supporting driving members 1124, thereby opening the two supporting plates 1121 to facilitate the placement of the packaged silicon wafers; after the packaged silicon wafers are stably placed, the side pressure assembly 113 is released, and the pressing plate 1111 is lifted along the second direction to finally release the packaged silicon wafers.

[0079] Reference Figure 1b to Figure 1i As shown, in one embodiment, the side pressure assembly 113 includes two side pressure baffles 1131 arranged opposite to each other, and the direction in which the two side pressure baffles 1131 are arranged opposite to each other is perpendicular to the direction in which the supporting plates 1121 included in the two supporting sub-components are arranged opposite to each other;

[0080] The side pressure assembly 113 further includes a side pressure driving member 1132, a side pressure transmission member 1133 and two side pressure adapters 1134, wherein the side pressure adapters 1134 are connected to the side pressure baffles 1131 in a one-to-one correspondence, the side pressure driving member 1132 is connected to the side pressure transmission member 1133, and the two side pressure adapters 1134 are both connected to the side pressure transmission member 1133;

[0081] The side pressure driving member 1132 can drive the two side pressure blocking pieces 1131 to move so that the two side pressure blocking pieces 1131 are closer to each other or farther away from each other.

[0082] In this specific example, the side pressure driving member 1132 transmits the driving force to the side pressure adapter 1134 through the side pressure transmission member 1133, and the side pressure adapter 1134 then drives the side pressure baffle 1131 connected thereto to move, so that the two side pressure baffles 1131 move closer to each other to clamp the first material, or move away from each other to release the first material.

[0083] Optionally, the side pressure driving member 1132 includes a motor and a reducer; the side pressure transmission member 1133 includes a belt and a pulley.

[0084] Reference Figure 1b As shown, in one embodiment, the stacking mechanism 11 also includes a rotating assembly 114, and the pressing assembly 111, the supporting assembly 112 and the side pressure assembly 113 are all connected to the rotating assembly 114, and the rotating assembly 114 can drive the pressing assembly 111, the supporting assembly 112 and the side pressure assembly 113 to rotate around the second direction.

[0085] In this specific example, the pressing assembly 111, the supporting assembly 112 and the side pressure assembly 113 can be rotated around the second direction as a whole, for example, by 90°, through the rotational force of the rotating assembly 114, so as to adapt to different material picking angles and material discharge angles. For example, when picking up materials, the two side pressure baffles 1131 are arranged relative to each other along the first direction, and the supporting plates 1121 included in the two supporting sub-components are arranged relative to each other along the third direction; and when discharging materials, the rotating assembly 114 is rotated by 90° through the rotational force, and the two side pressure baffles 1131 are arranged relative to each other along the third direction, and the supporting plates 1121 included in the two supporting sub-components are arranged relative to each other along the first direction.

[0086] Optionally, the rotating assembly 114 may include a motor, a reducer and a coupling; the rotating assembly 114 is connected to the pressing assembly 111, the supporting assembly 112 and the side pressure assembly 113 through a mounting plate, and the specific structure and setting position of the mounting plate can be adjusted according to actual conditions.

[0087] Reference Figure 1a As shown, the first direction is direction a, the second direction is direction b, and the third direction is direction c. The first direction, the second direction, and the third direction are mutually at predetermined angles; for example, the first direction, the second direction, and the third direction are mutually perpendicular. Of course, the predetermined angle is not necessarily 90°, but can be other angles.

[0088] In addition, the stacking mechanism 11 is further provided with a first pressure regulating valve 115 , and the first pressure regulating valve 115 is used to adjust the pressure output of the pressing assembly 111 .

[0090] The first carrier 141 and the second carrier 142 are arranged adjacent to each other along a first direction, and the first carrier 141 and the second carrier 142 are used to carry the first material and / or the second material respectively;

[0091] The first positioning component 143 is disposed correspondingly to the first carrier 141 , and the second positioning component 144 is disposed correspondingly to the second carrier 142 ;

[0092] The first positioning assembly 143 and the second positioning assembly 144 are both connected to the first positioning drive 145, and the first positioning drive 145 drives the first positioning assembly 143 to move along the first direction to position the first material and / or the second material carried by the first carrier 141 in the first direction; the first positioning drive 145 drives the second positioning assembly 144 to move along the first direction to position the first material and / or the second material carried by the second carrier 142 in the first direction.

[0093] In this specific example, the load-bearing and positioning platform 14 includes a base 140, and the first platform 141 and the second platform 142 are both mounted on the base 140. The first platform 141 and the second platform 142 can perform stacking operations at the same time to improve work efficiency. The first platform 141 and the second platform 142 can also work alternately; for example, after the first material and the second material carried on the first platform 141 complete the stacking operation, while the manipulator takes the first material and the second material from the first platform 141, the next stacking operation can be started on the second platform 142, thereby saving work cycles. In addition, the first platform 141 and the second platform 142 can also correspond to carrying materials of different grades, respectively, thereby improving the versatility of the load-bearing and positioning platform 14.

[0094] During the positioning operation, the first positioning driver 145 drives the first positioning assembly 143 and the second positioning assembly 144 to move simultaneously in the first direction, thereby simultaneously positioning the materials carried by the first carrier 141 and the second carrier 142 in the first direction to improve the efficiency of the positioning operation.

[0095] Reference Figure 1j~Figure 1l As shown, in one embodiment, the first positioning assembly 143 includes a first positioning plate 1431 and a second positioning plate 1432 that are arranged opposite to each other, and the second positioning assembly 144 includes a third positioning plate 1441 and a fourth positioning plate 1442 that are arranged opposite to each other; the second positioning plate 1432 and the third positioning plate 1441 are arranged opposite to each other;

[0096] The first positioning plate 1431 and the third positioning plate 1441 are connected to each other and are commonly connected to the first positioning driver 145 ; the second positioning plate 1432 and the fourth positioning plate 1442 are connected to each other and are commonly connected to the first positioning driver 145 .

When the driving motor 1451 drives the transmission pulley 1452 to rotate and thus drives the transmission belt 1453 to rotate clockwise, the first positioning plate 1431 and the second positioning plate 1432 are close to each other, and at the same time, the third positioning plate 1441 and the fourth positioning plate 1442 are also close to each other; when the driving motor 1451 drives the transmission pulley 1452 to rotate and thus drives the transmission belt 1453 to rotate counterclockwise, the first positioning plate 1431 and the second positioning plate 1432 are separated from each other, and at the same time, the third positioning plate 1441 and the fourth positioning plate 1442 are also separated from each other.

[0098] Reference Figure 1j~Figure 1l As shown, in one embodiment, the carrier positioning platform 14 also includes a third positioning component 146 and a fourth positioning component 147. The third positioning component 146 is arranged corresponding to the first carrier 141, and the third positioning component 146 positions the first material and / or the second material carried by the first carrier 141 in a third direction; the fourth positioning component 147 is arranged corresponding to the second carrier 142, and the fourth positioning component 147 positions the first material and / or the second material carried by the second carrier 142 in a third direction.

[0099] In this specific example, the carrier positioning platform 14 also includes a third positioning assembly 146 corresponding to the first carrier 141, and a fourth positioning assembly 147 corresponding to the second carrier 142. Optionally, the third positioning assembly 146 includes a second positioning driver 1461 and a fifth positioning plate 1462 connected to each other, and the second positioning driver 1461 can drive the fifth positioning plate 1462 to move along the third direction to abut and position the material carried by the first carrier 141 in the third direction; the fourth positioning assembly 147 includes a third positioning driver 1471 and a sixth positioning plate 1472, and the third positioning driver 1471 can drive the sixth positioning plate 1472 to move along the third direction to abut and position the material carried by the second carrier 142 in the third direction. Optionally, the second positioning driver 1461 and the third positioning driver 1471 are both cylinders.

[0100] The carrying and positioning platform 14 can accurately position the materials carried on the first platform 141 and the second platform 142, thereby ensuring the smooth progress of subsequent processes; for example, when the robot arm subsequently takes materials from the carrying and positioning platform 14, it can accurately and smoothly grab the materials.

[0101] According to another embodiment of the present application, a stacking method is provided, using the stacking device 1 as described above, the stacking method comprising:

[0102] The second material is transported to the carrying and positioning platform 14 by the suction cup mechanism 12, and the second material is positioned by the carrying and positioning platform 14;

[0103] Then, the stacking mechanism 11 transports the first material from the intermediate transfer platform 13 to the carrying and positioning platform 14 and places the first material on the second material, and the carrying and positioning platform 14 positions the first material;

[0104] The above steps are repeated until a first predetermined amount of the first material and a second predetermined amount of the second material are stacked; wherein the first material and the second material are alternately arranged.

[0105] In the stacking method provided in the embodiment of the present application, referring to Figure 2a As shown, a single second material is transported to the carrying and positioning platform 14 by the suction cup mechanism 12 each time, and a single first material is transported from the intermediate transfer platform 13 to the carrying and positioning platform 14 by the stacking mechanism 11 each time; the first material is, for example, a package of silicon wafers 01, and the second material is, for example, pearl cotton 02. Pearl cotton 02 and packaged silicon wafers 01 are alternately stacked, and the bottom layer is pearl cotton 02 to protect the packaged silicon wafers; and, in order to improve the protective effect on the packaged silicon wafers, after the first predetermined number of packaged silicon wafers are transported, a piece of pearl cotton can be transported by the suction cup mechanism 12 and stacked on the top layer to ensure that the bottom layer and the top layer are both pearl cotton 02; that is, the second predetermined number is 1 greater than the first predetermined number.

[0106] According to another embodiment of the present application, a stacking method is provided, using the stacking device 1 as described above, the stacking method comprising:

[0107] The second material is transported to the intermediate transfer platform 13 by the suction cup mechanism 12; then, at the intermediate transfer platform 13, the first material is placed on the second material to form a stacking group;

[0108] The stacking group is transported from the intermediate transfer platform 13 to the carrying and positioning platform 14 by the stacking mechanism 11, and the stacking group is positioned by the carrying and positioning platform 14;

[0109] The above steps are repeated until a predetermined number of stacking groups are stacked.

[0110] In the stacking method provided in the embodiment of the present application, referring to Figure 2bAs shown, firstly, a first material and a second material are stacked and placed on the intermediate transfer platform 13 to form a stacking group; the first material is, for example, a packaged silicon wafer 01, and the second material is, for example, pearl cotton 02. For example, the suction cup mechanism 12 sucks a piece of pearl cotton to the intermediate transfer platform 13, and then the conveying mechanism 16 conveys the packaged silicon wafers after bagging and folding from the previous process to the intermediate transfer platform 13 and places them on the pearl cotton, and a piece of pearl cotton and a package of packaged silicon wafers form a stacking group 001; then the stacking group 001 is conveyed from the intermediate transfer platform 13 to the bearing and positioning platform 14 by the stacking mechanism 11, and the stacking group is positioned by the bearing and positioning platform 14. Since the stacking mechanism 11 conveys a stacking group each time, the pearl cotton can protect the packaged silicon wafers in the stacking group, so the damage to the packaged silicon wafers that may be caused during the conveying process can be reduced to a certain extent. After the multiple stacking groups are stacked on the supporting positioning platform 14, in order to improve the protection of the packaged silicon wafers, a piece of pearl cotton 02 can be moved by the suction cup mechanism 12 and stacked on the multiple stacking groups to ensure that the bottom and top layers are both pearl cotton 02.
