A battery cell testing system Technical Field

[0001] This utility model relates to the field of solar cell technology, and in particular to a cell testing system. Background Technology

[0002] With the steady development of photovoltaic solar cells, users have put forward higher requirements for the performance and layout of cell testing systems. Generally, the length of the cell testing system along the transmission direction of the cells is too long, resulting in an excessive amount of factory space occupied by the cell testing system, which brings high cost pressure to users.

This allows the cell testing system to meet the cell testing requirements and the space required for the operation of the battery pack testing system. At the same time, compared with battery testing systems in related technologies, the total length L of the battery testing system in this embodiment is smaller, which can reduce the waste of layout space and thus reduce the user's costs in terms of layout space, equipment operation and maintenance.

[0042] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0043] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0044] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0045] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0046] In one specific embodiment, this application provides a solar cell testing system. Referring to FIG1, the solar cell testing system includes a batching station 1, a loading station 2, and an inspection station 3. The solar cell testing system also includes a conveying mechanism 4, which is used to convey solar cells between the batching station 1, the loading station 2, and the inspection station 3. The batching station 1 is used for quality inspection and sorting of the solar cells, the loading station 2 is used for loading the solar cells to be tested into the solar cell testing system, and the inspection station 3 is used for inspecting the solar cells to be tested.

[0047] In this solution, a conveying mechanism 4 is set up between the batching station 1, the loading station 2, and the testing station 3 to ensure the automated operation of the cell conveying in the cell testing system. The setting of the conveying mechanism 4 saves a lot of labor and time costs.

[0048] Referring to Figure 1, the total length of the cell testing system along the transport direction of the cell is L, 3000mm≤L≤3500mm. For example, the total length L of the cell testing system can be 3000mm, 3100mm, 3150mm, 3200mm, 3300mm, 3400mm, 3500mm, etc.

[0049] In this embodiment, when 3000mm≤L≤3500mm, the total length L of the cell testing system along the cell transmission direction is moderate, ensuring that equipment meeting the performance requirements of the cell testing system can be placed. This allows the cell testing system to meet the cell testing requirements and the space required for the operation of the battery pack testing system. At the same time, compared with battery testing systems in related technologies, the total length L of the battery testing system in this embodiment is smaller, which can reduce the waste of layout space and thus reduce the user's costs in terms of layout space, equipment operation and maintenance.

[0050] In one specific embodiment, referring to Figure 1, the total length L of the cell testing system is specifically 3200 mm.

[0051] In one feasible solution, the total length of the cell testing system is 6500mm. To address the issue of the excessive length of the cell testing system, a redesign of the entire cell testing system can reduce its total length along the cell transport direction from 6500mm to 3200mm.

[0052] In other embodiments, the total length L of the battery cell testing system may be 3250mm, 3300mm, or 3100mm.

[0053] In one specific embodiment, the inspection station 3 is used to inspect the solar cells to be tested, thereby determining whether the solar cells meet the requirements. Referring to Figure 1, along the transport direction of the solar cells, the length of the inspection station 3 in the solar cell testing system is B, 2000mm≤B≤2500mm. For example, the length B of the inspection station 3 can be 2000mm, 2050mm, 2100mm, 2200mm, 2300mm, 2400mm, 2500mm, etc.

[0054] In this embodiment, when 2000mm≤B≤2500mm, the length B of the inspection station 3 along the transport direction of the battery cell in the battery cell testing system is moderate, ensuring that equipment meeting the performance requirements of the inspection station 3 in the battery cell testing system can be placed, thereby meeting the testing needs of the battery cells and enabling the battery cell testing system to perform high-precision testing of the battery cells. At the same time, the length of the inspection station 3 in this battery cell testing system is not too large, thus meeting the space required for the operation of the inspection station 3 in the battery pack testing system while reducing waste of layout space, thereby reducing the user's costs in terms of layout space, equipment operation and maintenance, etc.

[0055] In one specific embodiment, referring to Figure 1, the length B of the detection station 3 can be 2331 mm.

[0056] In other embodiments, the length B of the inspection station 3 can also be 2000mm, 2050mm, 2400mm, etc.

[0057] In one specific embodiment, referring to Figure 1, along the transport direction of the battery cells, the sum of the lengths of the batching station 1 and the loading station 2 is A, where 500mm ≤ A ≤ 1500mm. For example, the sum of the lengths A of the batching station 1 and the loading station 2 can be 500mm, 600mm, 700mm, 800mm, 1000mm, 1200mm, 1500mm, etc.

[0058] In this embodiment, the sum A of the lengths of the batching station 1 and the loading station 2 along the cell transport direction in the cell testing system is moderate, ensuring that equipment meeting the performance requirements of the batching station 1 and the loading station 2 in the cell testing system can be placed. This satisfies the space requirements for the operation of the batching station 1 and the loading station 2 in the battery pack testing system while reducing wasted layout space, thereby alleviating user costs related to layout space, equipment operation and maintenance, etc. Furthermore, the moderate length A of the batching station 1 and the loading station 2 in this embodiment will not cause the length B of the detection station 3 to be too small, thus affecting the detection accuracy of the detection station 3 and preventing a reduction in the detection accuracy of the cell testing system.

[0059] In one specific embodiment, the sum A of the lengths of the batching station 1 and the loading station 2 along the transport direction of the battery cells can be 869 mm.

[0060] In one specific embodiment, referring to FIG1, along the transport direction of the battery cells, the loading station 2 is located between the batching station 1 and the inspection station 3.

[0061] In this scheme, after the solar cells in the cell testing system complete quality inspection and sorting at the batching station 1, they are transported to the loading station 2 via the conveyor mechanism 4. The loading station 2 performs precise positioning, efficient transmission, and pre-processing of the solar cells to ensure that they enter the subsequent testing station 3 in the correct posture. After the loading station 2 completes its work, it transports the solar cells to the testing station 3 via the conveyor mechanism 4. The testing station 3 performs electrical performance testing, sorting, and structural defect diagnosis on the solar cells to complete the process of the solar cell testing system in this scheme. Finally, the conveyor mechanism 4 transports the tested solar cells from the testing station 3 to the exit, at which point the process of the solar cell testing system ends.

[0062] In one specific embodiment, referring to Figure 1, the inspection station 3 includes an IV sorting mechanism and an EL inspection mechanism. The IV sorting mechanism performs electrical performance characteristic tests on the solar cells and connects the tested solar cells to the EI inspection mechanism after sorting and testing. The EL inspection mechanism detects internal defects in the solar cells, such as cracks or microcracks. The IV sorting mechanism and the EL inspection mechanism complement each other and work synergistically on the production line. The IV sorting mechanism focuses on sorting based on electrical performance testing, while the EL inspection mechanism focuses on detecting structural defects in the solar cells. Both mechanisms ensure the quality of the solar cells from two dimensions: electrical performance testing and defect diagnosis. The combination of the IV sorting mechanism and the EL inspection mechanism can comprehensively evaluate the performance and quality of the solar cells.

[0063] In the solar cell testing system, testing station 3, consisting of the IV sorting mechanism and the EL testing mechanism, is the core link for quality control and performance evaluation. Integrating the IV sorting mechanism and the EL testing mechanism into the same station and achieving simultaneous testing at both stations via the conveyor mechanism 4 shortens the testing cycle and improves space utilization.

[0064] In other embodiments, the testing station 3 may also include other testing mechanisms, which can be set according to the testing requirements of the battery cells. This application embodiment does not specifically limit the type and number of testing mechanisms on the testing station 3.

[0065] In one specific embodiment, referring to Figure 1, the cell testing system does not include front / back inspection stations. Eliminating the front / back inspection stations further reduces the total length L of the cell testing system along the cell transport direction. Specifically, in this solution, the cell type used in the cell testing system refers to cell types that do not require front / back inspection, such as single-sided cells, highly integrated design cells, standardized products with mature processes, and specially packaged cells. This ensures that the cell testing system without front / back inspection stations still maintains complete testing functionality and does not affect the operation of the cell testing system.

[0066] When the cell testing system is used to test cells requiring front / back testing, such as bifacial cells, a front / back testing mechanism can be set up outside the cell testing system. For example, a half-cell testing machine with a front / back testing station can be set up outside the cell testing system. The cell testing system in this embodiment is a testing system without a front / back testing mechanism.

[0067] In one specific embodiment, referring to Figure 1, the loading station 2 has a manual loading port. In this solution, when the solar cells in the solar cell testing system arrive at the batching station 1, there may be a situation where the number of solar cells remaining after the quality inspection and sorting are completed at the batching station 1 is too small, which may lead to the subsequent testing station 3 running idle due to the insufficient number of solar cells, resulting in waste.

[0068] In this solution, a manual feeding port is set up at the feeding station 2 to ensure that if the number of remaining cells is too small after the quality inspection and sorting at the batch closing station 1, manual feeding can be carried out to correct the deviation in time and ensure that the cells enter the testing process correctly, thereby avoiding the waste of production capacity during the operation of the cell testing system.

[0069] In one specific embodiment, the cell testing system includes at least one batching station 1 and at least one loading station 2. In this solution, because the testing cycle time of the testing mechanism in the testing station 3 is shortened, the batch size is greatly reduced. Accordingly, in this embodiment, the batching station 1 can be reduced to one, and the loading station 2 can also be reduced to one. This avoids the waste caused by the machine running idle when there are too many batching stations 1, and enables the batching station 1 and the loading station 2 to match the capacity of the testing station 3. This ensures the coordinated operation of the batching station 1 and the loading station 2, and also provides sufficient guarantee for the subsequent operation of the testing station 3.

[0070] In the above embodiments, as shown in FIG2, the batching station 1 includes a first batching station 11 and at least one second batching station 12. The conveying mechanism 4 is arranged along the conveying direction of the battery cells, the first batching station 11 is arranged on the conveying mechanism 4 along the conveying direction of the battery cells, and the second batching station 12 is located on one side or both sides of the first batching station 11.

[0071] When the battery cell testing system is operating normally, that is, when the batching station 1, the loading station 2 and the testing station 3 are all working normally, the first batching station 11 is used to perform quality inspection and sorting of the battery cells. The battery cells transported to the first batching station 11 by the conveying mechanism 4 can be transported towards the loading station 2 under the action of the conveying mechanism 4. At this time, the second batching station 12 is in a non-working state.

[0072] When the loading station 2 and / or the inspection station 3 malfunction, the solar cells on the first batching station 11 cannot be transferred to the downstream loading station 2. At this time, the first robot (not shown in Figure 2, the first robot used to transfer solar cells) can transport the solar cells on the first batching station 11 to the second batching station 12. The second batching station 12 is used to temporarily store the solar cells transported from upstream to the first batching station 11.

[0073] In this embodiment, the second batching station 12 can quickly switch the working state of the batching station 1 to cope with sudden failures. When the main line of the cell testing system is interrupted due to equipment failure, maintenance or accident, the first robot arm set at the batching station 1 will start immediately to transport the cells from the first batching station 11 to the second batching station 12. This avoids a large accumulation of cells on the first batching station 11, and allows the equipment upstream of the batching station 1 to operate normally when the loading station 2 and / or the testing station 3 fail, without the need for the entire cell testing system to be shut down, thus improving the efficiency of the cell testing system.

[0074] In one specific embodiment, as shown in FIG1, the cell inspection system may further include a first track 13 and a second track (not shown in FIG1). The first track 13 may extend along the width direction of the cell inspection system (i.e., the distribution direction of the first batching station 11 and the second batching station 12), and the second track may extend along the height direction of the cell inspection system. A first robotic arm is slidably connected to the first track 13, enabling the first robotic arm to slide along the first track 13. The first track 13 is slidably connected to the second track, enabling the first track 13 to drive the first robotic arm to slide along the second track, thereby moving closer to or away from the first batching station 11 and the second batching station 12 along the height direction of the cell inspection system.

[0075] When the equipment downstream of the batching station 1 malfunctions, the first robotic arm slides along the first track 13, aligning itself with the first batching station 11. The first track 13 then moves the first robotic arm along the second track, bringing it closer to the first batching station 11. The first robotic arm grabs the battery cells located at the first batching station 11, and the first track 13 moves the first robotic arm away from the first batching station 11 along the second track. The first robotic arm then slides along the first track 13 until it aligns with the second batching station 12, and the first track 13 moves the first robotic arm closer to the second batching station 12 along the second track. The battery cells on the first robotic arm are then placed on the second batching station 12.

[0076] In other embodiments, the cell inspection device may include a first track 13, which may extend along the width direction of the cell inspection system (i.e., the distribution direction of the first batching station 11 and the second batching station 12), and the first robot arm may be a telescopic structure. When the first robot arm slides along the first track 13 to align with the first batching station 11 or the second batching station 12, the first robot arm extends to approach the first batching station 11 or the second batching station 12, grabs or puts down the cell, and then retracts to move away from the first batching station 11 or the second batching station 12.

[0077] Therefore, the specific structure of the first robotic arm and the track is not limited in the embodiments of this application.

[0078] In the above embodiments, as shown in FIG3, the loading station 2 includes at least one manual loading station 21, which is located on at least one side of the conveying mechanism 4. The operator can replenish the battery cells onto the manual loading station 21, and under the action of a second robot arm (not shown in FIG3) installed at the loading station 2, the battery cells on the manual loading station 21 can be transported to the conveying mechanism 4, so that the battery cells can be conveyed towards the inspection station 3 downstream of the loading station 2 under the action of the conveying mechanism 4.

[0079] In one specific embodiment, as shown in FIG1, the cell detection system may further include a third track 22 and a fourth track (the fourth track is not shown in FIG1). The third track 22 extends along the width direction of the cell detection system, and the fourth track extends along the height direction of the cell detection system. A second robotic arm is slidably connected to the third track 22, allowing the second robotic arm to slide along the third track 22. The third track 22 is also slidably connected to the fourth track, allowing the third track 22 to drive the second robotic arm to slide along the fourth track, thereby approaching the manual loading station 21 along the height direction of the cell detection system. The second robotic arm then picks up the cell located at the manual loading station 21. During the process of the third track 22 driving the second robotic arm to slide along the fourth track, the second robotic arm can also move closer to or further away from the conveying mechanism 4 along the height direction of the cell detection system, thereby placing the cell on the second robotic arm onto the conveying mechanism 4.

[0080] In other embodiments, the cell inspection device may include a third track 22, which may extend along the width of the cell inspection system. The second robotic arm may be a telescopic structure. When the second robotic arm slides along the third track 22 to align with the manual loading station 21, the second robotic arm extends to approach the manual loading station 21. After the second robotic arm grabs the cell located at the manual loading station 21, the second robotic arm retracts and slides along the third track 22 to align with the conveying mechanism 4. The second robotic arm extends to place the cell on the second robotic arm onto the conveying mechanism 4.

[0081] Therefore, the specific structure of the second robotic arm and the track is not limited in the embodiments of this application.

[0082] In this embodiment, at least one manual loading station 21 is set up at the loading station 2. When the number of remaining battery cells after the batching station 1 completes quality inspection and sorting is too small or the equipment upstream of the loading station 2 (e.g., the batching station 1) malfunctions, the operator can manually replenish the loading and make timely corrections and adjustments to ensure that the battery cells correctly enter the testing process. This way, when the station upstream of the loading station 2 malfunctions, the entire battery cell testing system does not need to be shut down, thereby avoiding the waste of production capacity during the operation of the battery cell testing system.

[0083] In the embodiment shown in Figure 3, manual feeding stations 21 can be provided on both sides of the conveying mechanism 4, so that battery cells can be replenished from both sides of the conveying mechanism 4. Of course, one or more manual feeding stations 21 can be provided on one or both sides of the conveying mechanism 4, and this application does not limit the number of manual feeding stations 21.

[0084] In the above embodiments, as shown in FIG4, the detection station 3 may include a turntable 31, a first working station 32, a second working station 33, a third working station 34, and a fourth working station 35. The turntable 31 is connected to a drive mechanism for driving the turntable 31 to rotate. The drive mechanism includes, but is not limited to, a stepper motor. The first working station 32, the second working station 33, the third working station 34, and the fourth working station 35 are all connected to the turntable 31 and can rotate under the drive of the turntable 31. The first working station 32, the second working station 33, the third working station 34, and the fourth working station 35 are evenly distributed, that is, the included angle between adjacent working stations among the first working station 32, the second working station 33, the third working station 34, and the fourth working station 35 is 90°.

[0085] As shown in Figure 1, the battery cell testing system includes a first position 3a, a second position 3b, a third position 3c, and a fourth position 3d located around the testing station. The first position 3a is equipped with a third robotic arm (not shown in Figure 1), the second position 3b is equipped with a pressing and testing device, and the third position 3c is equipped with a fourth robotic arm (not shown in Figure 1). The third robotic arm is used to transport the battery cells from the conveyor mechanism 4 upstream of the testing station 3 to the working position at the first position 3a. The pressing and testing device is used to perform pressing and testing on the battery cells located at the second position 3b. The fourth robotic arm is used to transport the battery cells located at the working position at the third position 3c to the conveyor mechanism 4 downstream of the testing station 3.

[0086] Referring to Figures 1 and 4, when the inspection station 3 is in the position shown in Figure 4, the first working station 32 is located at position 3a, meaning the battery cells on the conveying mechanism 4 can be transported to this first working station 32. The second working station 33 is located at position 3b, meaning a pressing detection device is installed at this position. When the loaded battery cells rotate to this position, pressing detection can be performed. The third working station 34 is located at position 3c, meaning that when the pressed-detected battery cells rotate to position 3c, they can be transported by the fourth robotic arm to the conveying mechanism 4, and then unloaded or transported to a station downstream of the inspection station 3. The fourth working station 35 is located at position 3d, meaning that the working station at position 3d is used to wait for battery cells; there are no battery cells at position 3d.

[0087] Taking the embodiment shown in Figure 4 as an example, after the third robotic arm transports the battery cells from the conveying mechanism 4 to the first working position 32 located at the first position 3a, the turntable 31 rotates 90° clockwise under the drive of the driving mechanism, causing the first working position 32 containing the battery cells to rotate to the second position 3b. At the second position 3b, the pressing and testing device performs pressing and testing on the battery cells. At the same time, after the turntable 31 rotates, the second working position 33 rotates to the third position 3c, so that the battery cells on the second working position 33 can be transported to the conveying mechanism 4 by the fourth robotic arm. The third working position 34 rotates to the fourth position 3d to wait for the battery cells. The fourth working position 35 rotates to the first position 3a, so that the battery cells on the conveying mechanism 4 can be transported to the fourth working position 35 by the third robotic arm. After the pressing test is completed, the turntable 31 continues to rotate 90° clockwise under the drive mechanism, causing the first working position 32, where the battery cells are placed, to rotate to the third position 3c. The fourth robotic arm can then transport the tested battery cells from the first working position 32 to the downstream conveying mechanism 4 to complete the battery cell testing. Simultaneously, after the turntable 31 rotates, the second working position 33 rotates to the fourth position 3d to wait for the battery cells, the third working position 34 rotates to the first position 3a, and the battery cells on the conveying mechanism 4 can be transported to the third working position 34 by the third robotic arm. The fourth working position 35 rotates to the second position 3b, where the pressing test equipment can perform pressing tests on the battery cells at the fourth working position 35.

[0088] In this embodiment, the testing station 3 is equipped with a rotary mechanical assembly line, which enables simultaneous operation of multiple processes, improves the tightness of process connection, reduces waiting time, and improves the working efficiency of the cell testing system. In addition, the rotary mechanical assembly line at the testing station 3 saves space in the cell testing system and improves space utilization.

[0089] In the above embodiments, the first robotic arm, the second robotic arm, the third robotic arm, and the fourth robotic arm can all be equipped with suction cups, thereby adsorbing the battery cells through the suction cups and reducing the damage to the battery cells caused by the robotic arms.
