[0041] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0042] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0044] The feeding and correction device 100 according to an embodiment of the present utility model will now be described in detail with reference to the accompanying drawings.

[0045] like Figures 1 to 3 As shown, the feeding and correction device 100 according to an embodiment of the present utility model includes: a conveying component 10 and a multi-axis correction component.

[0046] Specifically, the conveying assembly 10 includes a frame 15 and a negative pressure conveyor belt 11. The negative pressure conveyor belt 11 is disposed on the frame 15 and is suitable for conveying and adsorbing solar cells. A multi-axis correction assembly is connected to the frame 15 and is configured to independently adjust the position of the frame 15 in multiple directions to correct the solar cells.

[0047] In other words, such as Figures 1 to 3 As shown, the feeding and correction device 100 according to an embodiment of the present invention mainly includes a conveying assembly 10 and a multi-axis correction assembly. The conveying assembly 10 mainly includes a frame 15, a drive wheel 12, a driven wheel 13, and a negative pressure conveyor belt 11. The drive wheel 12 and the driven wheel 13 are spaced apart along the length of the conveying assembly 10. The drive wheel 12 and the driven wheel 13 are rotatably mounted on the frame 15 around their own axes. The drive wheel 12 and the driven wheel 13 are located inside the negative pressure conveyor belt 11, and the drive wheel 12 and the driven wheel 13 are respectively engaged with the negative pressure conveyor belt 11. Thus, the rotation of the drive wheel 12 can drive the negative pressure conveyor belt 11 to rotate, thereby conveying the solar cells through the negative pressure conveyor belt 11. The solar cells can be photovoltaic solar cells.

[0048] like Figure 1 As shown, specifically, the conveying assembly 10 includes two negative pressure conveyor belts 11, which are spaced apart along the width of the conveying assembly 10. Each negative pressure conveyor belt 11 is provided with a corresponding drive wheel 12 and a driven wheel 13. The drive wheels 12 of the two negative pressure conveyor belts 11 can be fixedly connected together by a connecting shaft, and a large gear is fixedly connected to the connecting shaft. The conveying assembly 10 also includes a drive motor 14, which is fixedly connected to the frame. A small gear is fixedly connected to the output end of the drive motor 14. The large gear and the small gear are connected by a transmission belt, so that the drive motor 14 can drive the two negative pressure conveyor belts 11 to move, thereby conveying the photovoltaic cells.

[0049] like Figure 1As shown, the frame 15 also has two negative pressure chambers. The air inlets of the negative pressure chambers can be connected to a fan. By drawing air from the fan, negative pressure can be generated in the negative pressure chambers. The upper side of the negative pressure chambers is an open end. The open ends of the two negative pressure chambers are respectively in contact with the inner wall surfaces of the two negative pressure conveyor belts 11. The two negative pressure conveyor belts 11 are provided with multiple adsorption holes that penetrate along their thickness direction. The adsorption holes are evenly distributed on the outer periphery of the negative pressure conveyor belts 11. In use, the negative pressure chambers can provide adsorption force to the adsorption holes on the negative pressure conveyor belts 11, so that the negative pressure conveyor belts 11 can adsorb photovoltaic cells while conveying them.

[0050] In this embodiment, the multi-axis correction component is connected to the frame 15 of the conveying component 10. The position of the frame 15 can be adjusted in multiple directions through the multi-axis correction component, thereby realizing the position adjustment of the negative pressure conveyor belt 11, and thus realizing the correction of the photovoltaic cells.

[0051] When the negative pressure conveyor belt 11 transports the photovoltaic cells on the negative pressure conveyor belt 11 to the designated position, if there is a positional deviation of the photovoltaic cells, the multi-axis correction component can adjust the position of the frame 15 in one or more directions according to the actual situation, thereby correcting the photovoltaic cells on the negative pressure conveyor belt 11 to the correct position.

[0052] Therefore, according to the feeding and correction device 100 provided in this embodiment, the photovoltaic cells can be transported to a designated position by the negative pressure conveyor belt 11, and the position of the photovoltaic cells can be corrected by adjusting the position of the frame 15 through the multi-axis correction component. Compared with the prior art, the handling and suction process of the transport arm is reduced, which effectively improves the correction efficiency of the photovoltaic cells and reduces the breakage rate of the photovoltaic cells. Moreover, the negative pressure conveyor belt 11 can adsorb the photovoltaic cells during the transportation and correction process, thereby avoiding the shaking of the photovoltaic cells and ensuring the accuracy of the position of the photovoltaic cells. Furthermore, the multi-axis correction component can also perform correction operation on the photovoltaic cells during the transportation process, which can further ensure the correction efficiency of the photovoltaic cells.

[0053] In some embodiments of this utility model, the multi-axis correction assembly includes: a first correction module 20, a second correction module 30, and a third correction module 40. The first correction module 20 is disposed on the frame 15 and is adapted to drive the frame 15 to move along a first direction. The second correction module 30 is disposed on the frame 15 and is adapted to drive the frame 15 to move along a second direction. The third correction module 40 is disposed on the frame 15 and is adapted to drive the frame 15 to rotate around a third-direction extended axis.

[0054] In other words, such as Figures 1 to 3As shown, the multi-axis correction assembly mainly includes a first correction module 20, a second correction module 30, and a third correction module 40. The first correction module 20 can be directly or indirectly connected to the frame 15 and can drive the frame 15 to move along a first direction, which can be any direction parallel to the bearing surface of the negative pressure conveyor belt 11 carrying the photovoltaic cells. The second correction module 30 can be directly or indirectly connected to the frame 15 and can drive the frame 15 to move along a second direction, which is parallel to the bearing surface of the negative pressure conveyor belt 11 carrying the photovoltaic cells and can be perpendicular to the first direction. The third correction module 40 can be directly or indirectly connected to the frame 15 and can drive the frame 15 to rotate around a third-direction axis, which can be a direction perpendicular to the bearing surface of the negative pressure conveyor belt 11 carrying the photovoltaic cells.

[0055] In this embodiment, when the photovoltaic cell shifts in the first direction, the first correction module 20 drives the frame 15 to move along the first direction, and the negative pressure conveyor belt 11 moves along with the frame 15, thereby correcting the photovoltaic cell to the correct position in the first direction. When the photovoltaic cell shifts in the second direction, the second correction module 30 drives the frame 15 to move along the second direction, and the negative pressure conveyor belt 11 moves along with the frame 15, thereby correcting the photovoltaic cell to the correct position in the second direction. When the photovoltaic cell shifts at an angle, the third correction module 40 can... The drive frame 15 rotates around a third-direction extended axis, and the negative pressure conveyor belt 11 moves together with the frame 15. This can correct the angle of the photovoltaic cell to the correct angle. However, since the relative position of the photovoltaic cell and the bearing surface does not change, the position of the photovoltaic cell in the first and second directions will be offset when the photovoltaic cell is transported. Therefore, when the photovoltaic cell is offset at an angle and the conveying component 10 is still transporting the photovoltaic cell, the third correction module 40 needs to work together with the first correction module 20 and the second correction module 30 to correct the photovoltaic cell to the correct position.

[0056] According to one embodiment of the present invention, the first of the first correction module 20, the second correction module 30 and the third correction module 40 is installed on the second, the second is installed on the third, and the frame 15 is installed on the third.

[0057] In other words, the installation positions of the first correction module 20, the second correction module 30, the third correction module 40, and the rack 15 include, but are not limited to, the following:

[0058] Case 1: The first correction module 20 is installed on the second correction module 30, the third correction module 40 is installed on the second correction module 30, and the frame 15 is installed on the third correction module 40.

[0059] Scenario 2: The first correction module 20 is installed on the third correction module 40, the second correction module 30 is installed on the first correction module 20, and the frame 15 is installed on the second correction module 30.

[0060] Case 3: The second correction module 30 is installed on the third correction module 40, the first correction module 20 is installed on the second correction module 30, and the frame 15 is installed on the first correction module 20.

[0061] Case 4: The second correction module 30 is installed on the first correction module 20, the third correction module 40 is installed on the second correction module 30, and the frame 15 is installed on the third correction module 40.

[0062] Case 5: The third correction module 40 is installed on the first correction module 20, the second correction module 30 is installed on the third correction module 40, and the frame 15 is installed on the second correction module 30.

[0063] Case 6: The third correction module 40 is installed on the second correction module 30, the first correction module 20 is installed on the third correction module 40, and the frame 15 is installed on the first correction module 20.

[0064] This ensures that the first correction module 20, the second correction module 30, and the third correction module 40 do not interfere with each other, which is beneficial for the first correction module 20, the second correction module 30, and the third correction module 40 to operate simultaneously to correct the position of the photovoltaic cells.

[0065] According to one embodiment of the present invention, the second correction module 30 is installed on the first correction module 20, the third correction module 40 is installed on the second correction module 30, and the frame 15 is installed on the third correction module 40.

[0066] Specifically, such as Figures 1 to 3 As shown, the second correction module 30 can be installed at the output end of the first correction module 20. The first correction module 20 can drive the second correction module 30 to move in the first direction. The third correction module 40 can be installed at the output end of the second correction module 30. The second correction module 30 can drive the third correction module 40 to move in the second direction. The frame 15 can be installed at the output end of the third correction module 40. The third correction module 40 can drive the frame 15 to rotate around the axis extending in the third direction.

[0067] Therefore, the first correction module 20, the second correction module 30, and the third correction module 40 do not affect each other, which is conducive to the simultaneous operation of the first correction module 20, the second correction module 30, and the third correction module 40 to correct the position of the photovoltaic cells; and the relative position of the third correction module 40 and the conveying component 10 will not change, which is more conducive to adjusting the angle of the photovoltaic cells.

[0068] In some optional examples of this utility model, the feeding and correction device 100 further includes a mounting base 50, and the first correction module 20 includes a first base 21 and a first driving member 22. The first base 21 is movably disposed on the mounting base 50 along a first direction. The second correction module 30 is mounted on the first base 21, and the first driving member 22 is mounted on the mounting base 50. The output end of the first driving member 22 is connected to the first base 21 to drive the first base 21 to move along the first direction.

[0069] In other words, such as Figure 1 As shown, the feeding and correction device 100 is provided with a mounting base 50, which provides a mounting position for the multi-axis correction assembly. Specifically, the first correction module 20 mainly includes a first base 21 and a first drive component 22. The first base 21 is located on the upper side of the mounting base 50, and a slide rail structure is provided between the first base 21 and the mounting base 50 to connect them, so that the first base 21 can be movably connected to the mounting base 50 along a first direction, which can be the width direction of the mounting base 50. The second correction module 30 can be installed on the first base 21, so that when the first base 21 moves along the first direction, the second correction module 30 can be driven to move synchronously. The first drive component 22 can be installed on the mounting base 50, and the output end of the first drive component 22 can be fixedly connected to the first base 21, so that the first base 21 can be driven to move along the first direction through the first drive component 22. The structure is simple and easy to assemble in production.

[0070] In some embodiments of this utility model, the first driving member 22 includes: a first lead screw 221, a first slider 222, and a first motor 223. The first lead screw 221 extends along a first direction and is rotatably mounted on the mounting base 50 around its own axis. The first slider 222 is threadedly connected to the first lead screw 221 and is connected to the first base 21. The first motor 223 is mounted on the mounting base 50, and the output end of the first motor 223 is connected to one end of the first lead screw 221 to drive the first lead screw 221 to rotate.

[0071] Specifically, such as Figure 1As shown, the first driving component 22 mainly includes a first lead screw 221, a first slider 222, and a first motor 223. The axis of the first lead screw 221 is parallel to the first direction. The mounting base 50 is fixedly connected to a first connecting seat suitable for mounting the first lead screw 221. The first lead screw 221 is rotatably connected to the first connecting seat. The first slider 222 is sleeved on the first lead screw 221 and is connected to the first lead screw 221 by a threaded connection. The first slider 222 is also fixedly connected to the first base 21, so that when the first lead screw 221 rotates, the first base 21 can be driven to move along the first direction through the first slider 222. The first motor 223 is fixedly connected to the first connecting seat, and the output end of the first motor 223 is fixedly connected to one end of the first lead screw 221, or connected to it through a gear or other transmission structure, so that the first motor 223 can drive the first lead screw 221 to rotate, thereby driving the first base 21 to move along the first direction through the first motor 223.

[0072] In this embodiment, the first driving member 22 formed by the first lead screw 221, the first slider 222 and the first motor 223 not only has good stability, but also has high precision, which can ensure the correction accuracy of the feeding correction device 100.

[0073] According to one embodiment of the present invention, the second correction module 30 includes: a second base 31 and a second driving member 32. The second base 31 is movably disposed on the first correction module 20 along a second direction. A third correction module 40 is installed on the second base 31. The second driving member 32 is installed on the first correction module 20. The output end of the second driving member 32 is connected to the second base 31 to drive the second base 31 to move along the second direction.

[0074] In other words, such as Figure 1 As shown, the second correction module 30 mainly includes a second base 31 and a second driving member 32. The second base 31 is located on the upper side of the first base 21, and a slide rail structure is provided between the second base 31 and the first base 21 to connect them, so that the second base 31 can be movably connected to the first base 21 along a second direction, which can be the length direction of the mounting base 50. The third correction module 40 can be installed on the second base 31, so that when the second base 31 moves along the second direction, the third correction module 40 can be driven to move synchronously. The second driving member 32 can be installed on the side wall of the first base 21, and the output end of the second driving member 32 can be fixedly connected to the second base 31, so that the second base 31 can be driven to move along the second direction through the second driving member 32. The structure is simple and easy to produce and assemble.

[0075] In some optional examples of this utility model, the second driving member 32 includes: a second lead screw 321, a second slider 322, and a second motor 323. The second lead screw 321 extends along a second direction and is rotatably mounted on the first correction module 20 about its own axis. The second slider 322 is threadedly connected to the second lead screw 321 and is connected to the second base 31. The second motor 323 is mounted on the first correction module 20, and the output end of the second motor 323 is connected to one end of the second lead screw 321 to drive the second lead screw 321 to rotate.

[0076] Specifically, such as Figure 1 As shown, the second driving component 32 mainly includes a second lead screw 321, a second slider 322, and a second motor 323. The axis of the second lead screw 321 is parallel to the second direction. A second connecting seat suitable for mounting the second lead screw 321 is fixedly connected to the side wall of the first base 21. The second lead screw 321 is rotatably connected to the second connecting seat. The second slider 322 is sleeved on the second lead screw 321 and is connected to the second lead screw 321 by a threaded connection. The second slider 322 is also fixedly connected to the second base 31, so that when the second lead screw 321 rotates, the second base 31 can be driven to move along the second direction through the second slider 322. The second motor 323 is fixedly connected to the second connecting seat, and the output end of the second motor 323 is fixedly connected to one end of the second lead screw 321, or connected to it through a gear or other transmission structure, so that the second motor 323 can drive the second lead screw 321 to rotate, thereby driving the second base 31 to move along the second direction through the second motor 323.

[0077] In this example, the second drive unit 32 formed by the second lead screw 321, the second slider 322 and the second motor 323 not only has good stability, but also has high precision, which can ensure the correction accuracy of the feeding correction device 100.

[0078] According to some embodiments of the present invention, both the first driving member 22 and the second driving member 32 are linear motors.

[0079] In some embodiments of this utility model, the third correction module 40 includes: a first connector 41, a second connector 42, and a third motor 43. The first connector 41 is installed on the second correction module 30 and has an installation space.

The third motor 43 is installed on the first connector 41 and is located in the installation space. The output end of the third motor 43 is connected to the second connector 42.

[0080] In other words, such as Figure 1As shown, the third correction module 40 according to the embodiment of the present utility model mainly includes a first connector 41, a second connector 42 and a third motor 43. The first connector 41 and the second connector 42 are rotatably connected together around a third-direction extending axis, so that the first connector 41 and the second connector 42 can form a transfer structure connecting the frame 15 and the second base 31. Specifically, the end of the first connector 41 away from the second connector 42 is fixedly connected to the second base 31, and the second connector 42 is fixedly connected to the lower side of the frame 15. The first connector 41 has a hollow frame structure, which makes the first connector 41 have an installation space. The third motor 43 can be installed in the installation space, thereby reducing the space occupied by the third correction module 40. The third motor 43 can be fixedly connected to the first connector 41, and the output end of the third motor 43 can be fixedly connected to the second connector 42, or connected to the second connector 42 through a gear reduction structure, etc., so that the second connector 42 can be driven to rotate by the third motor 43. The structure is simple and it is convenient to adjust the angle of the frame 15.

[0081] In some optional embodiments of this invention, the third correction module 40 is configured as a DD motor.

[0082] According to one embodiment of the present invention, the multi-axis correction assembly is configured as a UVW correction platform.

[0083] In this embodiment, the UVW correction platform can meet most of the user's correction needs, and the UVW correction platform can be directly purchased, has good reliability, and is conducive to the production and manufacturing of the feeding correction device 100.

[0084] In some embodiments of this utility model, the feeding and correction device 100 includes two conveying components 10 spaced apart, and each conveying component 10 is respectively provided with a multi-axis correction component.

[0085] In other words, the feeding and correction device 100 can be provided with two conveying components 10 arranged side by side. For example, the two conveying components 10 can be distributed at intervals along the first direction, and each conveying component 10 is provided with a multi-axis correction component, so that the feeding and correction device 100 can simultaneously convey two photovoltaic cells (e.g., the first half and the second half), which can effectively improve the working efficiency of the production line and is beneficial to the feeding and correction of the two halves of the photovoltaic cells.

[0086] The present invention also provides a feeding and correction system, including the feeding and correction device 100 described in any of the above embodiments and a visual positioning unit. The visual positioning unit is electrically connected to the multi-axis correction component and is used to take pictures and position the battery cells on the conveying component 10.

[0087] In other words, the feeding and correction system according to the present invention mainly includes a feeding and correction device 100 and a visual positioning unit. The feeding and correction device 100 is the feeding and correction device 100 described in any of the above embodiments. The visual positioning unit mainly includes a CCD image sensor. The visual positioning unit is directly or indirectly electrically connected to the multi-axis correction component. The visual positioning unit can be located above the conveying component 10. The visual positioning unit can take pictures and position the photovoltaic cells on the conveying component 10, thereby providing the multi-axis correction component with the specific position of the photovoltaic cells (i.e., the offset of the photovoltaic cells). The multi-axis correction component can correct the offset according to the specific position of the photovoltaic cells.

[0088] Since the feeding and correction device 100 according to the present utility model has the above-mentioned technical effects, the feeding and correction system according to the present utility model also has the corresponding technical effects, which will not be described again in this embodiment.

[0089] According to the embodiment of this utility model, when the feeding and correction system is in use, the negative pressure conveyor belt 11 can transport the photovoltaic cells from the initial position to the designated position. After the photovoltaic cells on the negative pressure conveyor belt 11 are displaced to the designated position, the visual positioning unit takes pictures to confirm the offset of the photovoltaic cells. If the photovoltaic cells are offset in the first direction, the first correction module 20 drives the frame 15 to move along the first direction to correct the position of the photovoltaic cells in the first direction. If the photovoltaic cells are offset in the second direction, the second correction module 30 drives the frame 15 to move along the second direction to correct the position of the photovoltaic cells in the second direction. If a deviation occurs simultaneously in the direction, the first correction module 20 drives the frame 15 to move along the first direction, while the second correction module 30 drives the frame 15 to move along the second direction, in order to correct the position of the photovoltaic cell in the first and second directions. If the photovoltaic cell has an angular deviation, the third correction module 40 drives the frame 15 to rotate around the axis extending in the third direction, thereby correcting the angle of the photovoltaic cell. If a deviation still exists in the first and / or second directions after the angle is corrected, the corresponding steps can be continued. After the material feeding and correction process is completed, the first correction module 20, the second correction module 30 and the third correction module 40 are reset to their initial state to facilitate the next material feeding and correction.

[0090] An embodiment of this utility model also provides a battery cell testing and sorting device, including the feeding and correction device 100 or feeding and correction system described in any of the above embodiments. Since the feeding and correction device 100 and feeding and correction system according to the embodiments of this utility model have the above-mentioned technical effects, the battery cell testing and sorting device according to the embodiments of this utility model also has corresponding technical effects, which will not be repeated in this embodiment.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
