Description

Technical Field

[0001] This application relates to the field of solar cell technology, and in particular to electrode grid line maintenance device and electrode grid line printing system. Background Technology

[0002] Screen printing is a crucial production process in solar cell manufacturing. The working principle of screen printing involves first laying a paste onto a screen with perforated patterns, then applying downward pressure to the screen using a squeegee that reciprocates across the screen. Under this pressure, the paste is forced onto the surface of the solar cell, forming the desired electrode grid lines.

[0003] During the printing of electrode grid lines, various factors such as screen quality, electrode grid line width, ink dryness, and printing parameter adjustments can cause varying degrees of quality defects, including breaks and uneven thickness, in some electrode grid lines. Since the width of electrode grid lines is typically between 25µm and 35µm, these abnormalities are not easily identifiable to the naked eye.

[0004] In current electrode grid line printing equipment, after the paste is printed on the solar cells, a random AOI (Automated Optical Inspection) unit checks the printed electrode grid lines. If any abnormalities are found, the machine issues an alarm, and then manual inspection is conducted to sort out the defective solar cells for isolation and removal from the production line. Finally, the defective solar cells are centrally reworked and repaired. However, when defective solar cells are removed from the production line and then centrally reworked and repaired, the electrode grid lines have already been dried and solidified, exhibiting a certain degree of hardness. This makes manual rework difficult and affects the accuracy and height / width quality of the repaired electrode grid lines. Furthermore, manual removal and subsequent manual rework can easily cause secondary damage to the solar cells, such as fragmentation and scratches. Utility Model Content

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0063] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0064] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0065] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0068] One embodiment of this application provides an electrode grid line printing system for printing electrode grid lines on a solar cell and for online repair of defective electrode grid lines. See also Figure 1 , Figure 1 A top view illustrating the structure of an electrode grid line printing system according to an embodiment of this application is shown. Specifically, the electrode grid line printing system of one embodiment includes a printing apparatus 10 and an electrode grid line inspection device 20. The printing apparatus 10 is used to print electrode grid lines on a solar cell and to inspect the printing quality of the solar cell grid lines after printing. The electrode grid line inspection device 20 is used to repair printing defects such as breaks in the electrode grid lines of abnormal solar cells online.

[0069] Specifically, see Figure 1 In some embodiments, the printing apparatus 10 includes a printing press 11, an AOI (Automated Optical Inspection) inspection mechanism 12, and a fourth conveying mechanism 13.

[0070] The printing press 11 is used to print electrode grid lines on solar cells. As is easily understood, the printing press 11 is equipped with a screen, a squeegee, and related moving parts. The printing press 11 first lays the paste on the screen, then applies a certain downward pressure to the screen through the squeegee, and moves the squeegee back and forth on the screen. Under the pressure of the squeegee, the paste is squeezed onto the surface of the solar cell, so that the paste forms electrode grid lines on the surface of the solar cell.

[0071] The AOI inspection mechanism 12 is connected to the printing press 11 and is used to inspect the printing quality of the electrode grid lines of the solar cells printed on the printing press 11. Specifically, the AOI inspection mechanism 12 can detect whether there are printing defects such as breaks, broken grids, or uneven thickness in the electrode grid lines of the solar cells. When a printing defect is detected in the electrode grid lines of the solar cells, the solar cells are determined to be abnormal and an alarm signal is issued.

[0072] The fourth conveying mechanism 13 is connected to the AOI inspection mechanism 12 and the electrode grid line repair device 20. The fourth conveying mechanism 13 is used to convey the solar cells. Specifically, when the AOI inspection mechanism 12 detects that the electrode grid line printing of the solar cell is normal, the fourth conveying mechanism 13 conveys the normal solar cell to the drying oven for drying. When the AOI inspection mechanism 12 detects an abnormal solar cell, the fourth conveying mechanism 13 conveys the abnormal solar cell to the electrode grid line repair device 20 for repair.

[0073] Specifically, in traditional printing equipment 10, when the AOI inspection mechanism 12 detects an abnormal solar cell, it typically only issues an alarm signal. Printing anomalies such as broken electrode grid lines or broken grids are not addressed promptly, and the abnormal solar cell continues to complete the entire printing process (including drying). Only after the abnormal solar cell has completed testing and sorting are workers isolating and removing it from the production line, and then reworking and repairing it in a centralized manner. However, when the abnormal solar cell is removed from the production line and then reworked, the electrode grid lines have already dried and solidified, exhibiting a certain degree of hardness, which is not conducive to manual rework and affects the accuracy and height / width quality of the repaired electrode grid lines. Furthermore, manual removal and rework can easily cause secondary damage such as fragmentation and scratches to the abnormal solar cell.

[0074] Based on this, an electrode grid line repair device 20 is also provided, used for online repair of printing defects such as breaks and broken grids in the electrode grid lines of abnormal solar cells during the solar cell printing process. See also Figures 2 to 4 In some embodiments, the electrode grid line maintenance device 20 includes a first conveying mechanism 21, a carrying mechanism 22, a visual inspection mechanism 23, and a repair mechanism 24.

[0075] The first conveying mechanism 21 is connected to the printing equipment 10. The first conveying mechanism 21 is used to acquire abnormal battery cells with printing defects from the printing equipment 10 and convey the abnormal battery cells to the repair station. Specifically, the first conveying mechanism 21 is connected to the fourth conveying mechanism 13 of the printing equipment 10. When the AOI inspection mechanism 12 of the printing equipment 10 detects an abnormal battery cell, the fourth conveying mechanism 13 conveys the abnormal battery cell to the first conveying mechanism 21, and then the first conveying mechanism 21 conveys the abnormal battery cell to the repair station.

[0076] A support mechanism 22 is installed at the maintenance station and is connected to the first conveying mechanism 21. The support mechanism 22 is used to support the abnormal battery cells conveyed by the first conveying mechanism 21. Specifically, the support mechanism 22 is used to support and fix the abnormal battery cells at the maintenance station.

[0077] A visual inspection mechanism 23 is installed at the maintenance station. The visual inspection mechanism 23 is used to acquire the location information of the printing defects of abnormal battery cells on the carrier mechanism 22. For example, the visual inspection mechanism 23 first acquires an image of the abnormal battery cell on the carrier mechanism 22, and then uses image recognition and processing technology to locate the location information of the printing defects of the abnormal battery cell through a program algorithm.

[0078] The repair mechanism 24 is set at the inspection station and can repair the printing defects according to the location information of the printing defects.

[0079] For example, the repair mechanism 24 can convert the location information of the printing defect point of the abnormal battery cell located by the visual inspection mechanism 23 into coordinate information, and move to the printing defect point of the abnormal battery cell according to the coordinate information to repair the printing defect point.

[0080] Furthermore, the repair mechanism 24 can use contact dispensing technology to output the same paste used for printing electrode grid lines to the printing defect points of the abnormal solar cell, so as to repair the printing defect points of the abnormal solar cell.

[0081] In the aforementioned electrode grid line inspection device 20 and electrode grid line printing system, when the AOI inspection mechanism 12 of the printing equipment 10 detects an abnormality in the battery cell printing, the fourth conveying mechanism 13 conveys the abnormal battery cell to the first conveying mechanism 21. The first conveying mechanism 21 then conveys the abnormal battery cell to the carrying mechanism 22, which receives the abnormal battery cell. Subsequently, the visual inspection mechanism 23 obtains the location information of the printing defect points of the abnormal battery cell. Then, the repair mechanism 24 repairs the printing defect points of the abnormal battery cell based on the location information of the printing defect points. Finally, the first conveying mechanism 21 conveys the repaired battery cell back to the fourth conveying mechanism 13, which then conveys the abnormal battery cell to the next process (e.g., the drying process). This achieves online repair of printing defects such as breaks and grid breaks in the electrode grid lines of abnormal battery cells during the battery cell printing process, improving the quality and yield of the screen printing of battery cells, while ensuring the accuracy of the repaired electrode grid lines. In addition, it avoids the problem of secondary damage such as fragmentation and scratches to battery cells caused by manual removal and rework.

[0082] See Figure 5 In some embodiments, the repair mechanism 24 includes a paste dispensing module 241 and a first drive module 242. The paste dispensing module 241 is used to output paste to the printing defect point. The first drive module 242 is connected to the paste dispensing module 241 and is used to drive the paste dispensing module 241 to move to the printing defect point.

[0083] For example, after the visual inspection mechanism 23 locates the printing defect point of the abnormal battery cell, the first drive module 242 converts the position information of the printing defect point into coordinate information, and drives the pulp dispensing module 241 to move to the printing defect point of the abnormal battery cell according to the coordinate information. Then, the pulp dispensing module 241 outputs pulp to the printing defect point, thereby realizing the repair of the printing defect point.

[0084] Specifically, in one embodiment, the printing defect point discharge module 241 includes a material bucket (not shown), a discharge component 2411, a conveying pipe (not shown), and a peristaltic pump (not shown). Wherein:

[0085] The material container is used to store the paste. For example, the paste may be the same paste used for printing electrode grid lines, such as silver paste.

[0086] The discharge component 2411 is disposed above the bearing mechanism 22 and connected to the first drive module. The discharge component 2411 is used to output slurry. For example, the discharge component 2411 is a tubular component. The discharge component 2411 is detachable. By replacing the discharge component 2411 with a different diameter, the electrode grid lines of different diameters can be repaired.

[0087] The feed pipe connects the feed tank to the discharge unit 2411, and the peristaltic pump is connected to the feed pipe. The peristaltic pump is used to pump the slurry in the feed tank along the feed pipe to the discharge unit 2411, so as to continuously supply slurry to the discharge unit 2411. Furthermore, by controlling the pumping pressure of the peristaltic pump, the speed at which the discharge unit 2411 outputs slurry can also be controlled, thereby ensuring the repair accuracy of the electrode grid lines.

[0088] See Figure 5 The first drive module 242 includes a first lifting module 2421, a first translation module 2422, and a second translation module 2423.

[0089] The first lifting module 2421 is connected to the pulp discharge module 241. The first lifting module 2421 is used to drive the pulp discharge module 241 to lift. Specifically, the first lifting module 2421 is connected to the discharge component 2411 of the pulp discharge module 241. By driving the discharge component 2411 to lift, the discharge component 2411 is brought closer to or away from the abnormal battery cell.

[0090] The first translation module 2422 is connected to the first lifting module 2421. The first translation module 2422 is used to drive the discharge module 241 to move along the first direction of the abnormal battery cell. For example, the first direction of the abnormal battery cell can be the length direction of the abnormal battery cell.

[0091] The second translation module 2423 is connected to the first translation module 2422, and the second translation module 2423 is used to drive the discharge module 241 to move along the second direction of the abnormal battery cell. For example, the second direction of the abnormal battery cell can be the width direction of the abnormal battery cell.

[0092] By linking the first lifting module 2421, the first translation module 2422, and the second translation module 2423, the discharge component 2411 of the discharge module 241 can be driven to move to any position on the abnormal battery cell, so as to ensure that the discharge module can repair the printing defects at any position on the abnormal battery cell.

[0093] For example, in some embodiments, the first lifting module 2421, the first translation module 2422 and the second translation module 2423 can all be cylinders, linear modules or electric push rods, etc., as long as they can drive the discharge component 2411 to make linear movements, and there are no restrictions here.

[0094] See Figure 5 In one embodiment, the visual inspection mechanism 23 includes a camera 231, a third translation module 232 and a fourth translation module 233.

[0095] Camera 231 is used to acquire image information of abnormal battery cells entering the inspection station, and to acquire the location information of printing defects on the abnormal battery cells based on the image information. For example, camera 231 can be a CCD (Charge-Coupled Device) camera 231, thereby acquiring image information of abnormal battery cells using CCD camera 231, and then using image processing algorithms to detect and locate printing defects on abnormal battery cells.

[0096] The third translation module 232 is connected to the camera 231. The third translation module 232 is used to drive the camera 231 to move along the first direction of the abnormal battery cell. For example, the first direction of the abnormal battery cell can be the length direction of the abnormal battery cell.

[0097] The fourth translation module 233 is connected to the third translation module 232. The fourth translation module 233 is used to drive the camera 231 to move along the second direction of the abnormal battery cell. For example, the second direction of the abnormal battery cell can be the width direction of the abnormal battery cell.

[0098] By linking the third translation module 232 and the fourth translation module 233, the camera 231 can be driven to move to any position on the abnormal battery cell, so as to ensure that the camera 231 can acquire image information at any position on the abnormal battery cell, so as to locate and repair the printing defect point at any position.

[0099] For example, in some embodiments, the third translation module 232 and the fourth translation module 233 can be cylinders, linear modules or electric push rods, etc., as long as they can drive the camera 231 to make linear movements, and there are no restrictions here.

[0100] For example, in some embodiments, the visual inspection mechanism 23 and the repair mechanism 24 are respectively disposed on both sides of the support mechanism 22, and in the height direction, the visual inspection mechanism 23 and the repair mechanism 24 are misaligned to prevent the visual inspection mechanism 23 and the repair mechanism 24 from interfering with each other during movement.

[0101] See Figure 5 In some embodiments, the supporting mechanism 22 includes a supporting platform 221 and a second driving module 222, wherein the supporting platform 221 is used to support the abnormal battery cell. The second driving module 222 is connected to the supporting platform 221 and is used to drive the supporting platform 221 to move, thereby adjusting the position of the supporting platform 221 and ensuring that the supporting platform 221 can stably receive the abnormal battery cell conveyed by the first conveying mechanism 21.

[0102] See Figure 5 In one embodiment, the second drive module 222 includes a second lifting module 2221, a fifth translation module 2222, and a sixth translation module 2223. The second lifting module 2221 is connected to the support platform 221 and is used to drive the support platform 221 to move up and down. The fifth translation module 2222 is connected to the support platform 221 and is used to drive the support platform 221 to move along a first direction of the abnormal solar cell. The sixth translation module 2223 is connected to the fifth translation module 2222 and is used to drive the pulp discharge module 241 to move along a second direction of the abnormal solar cell.

[0103] Specifically, the first conveying mechanism 21 first conveys the abnormal battery cell to the top of the carrying mechanism 22. Then, the vision inspection mechanism 23 acquires an image of the abnormal battery cell to locate its position. Subsequently, the fifth translation module 2222 and the sixth translation module 2223 jointly drive the carrying platform 221 to move according to the position of the abnormal battery cell to ensure that the carrying platform 221 is aligned with the abnormal battery cell. Finally, the second lifting module 2221 drives the carrying platform 221 to lift so that the carrying platform 221 receives and supports the abnormal battery cell.

[0104] See Figure 6 In some embodiments, the support platform 221 has a clearance groove 2211 for the passage of the first conveying mechanism 21. This prevents the support platform 221 from interfering with the first conveying mechanism 21 after it has been raised into position.

[0105] Specifically, the support platform 221 includes multiple sub-plates. For example, in this embodiment, the support platform 221 includes three sub-plates, with clearance grooves 2211 formed between adjacent sub-plates. Furthermore, the support platform 221 also includes a connecting plate that connects to the bottom of all sub-plates so that the second drive module 222 can drive all sub-plates to move synchronously.

[0106] See Figure 6 In some embodiments, the support platform 221 is provided with a vacuum suction hole 2212, which is used to adsorb and fix the abnormal battery cell. Specifically, the vacuum suction hole 2212 is connected to a vacuum generating device. By drawing a vacuum into the vacuum suction hole 2212 through the vacuum generating device, the abnormal battery cell can be adsorbed and fixed on the support platform 221, preventing the abnormal battery cell from shifting or misaligning during the repair process.

[0107] See Figure 3 In one embodiment, the electrode grid line repair device 20 further includes a first buffer mechanism 25 and a second conveying mechanism 27, wherein: the first buffer mechanism is used to store the abnormal battery cell to be repaired, the second conveying mechanism 27 is intersected with the first conveying mechanism 21, and the second conveying mechanism 27 is used to transfer the abnormal battery cell to be repaired between the first buffer mechanism 25 and the first conveying mechanism 21.

[0108] Specifically, when a faulty battery cell is being repaired on the carrier mechanism 22, the second conveying mechanism 27 can temporarily transport the faulty battery cell to be repaired from the first conveying mechanism 21 to the first buffer mechanism 25. After the faulty battery cell on the carrier mechanism 22 is repaired and sent out of the carrier mechanism 22, the second conveying mechanism 27 takes out the faulty battery cell to be repaired from the first buffer mechanism 25 and sends it back to the first conveying mechanism 21, so that the first conveying mechanism 21 can transport it to the carrier mechanism 22. This avoids the occurrence of faulty battery cell blockage or stacking, ensuring the smooth operation of the electrode grid line repair device.

[0109] See Figure 7 In some embodiments, the first buffer mechanism 25 includes a first support frame 251, which has multiple first buffer layers 252 spaced apart in the height direction. Each first buffer layer 252 can hold one faulty battery cell, thus enabling the first buffer mechanism 25 to hold multiple faulty battery cells simultaneously. Correspondingly, the second conveying mechanism 27 is vertically adjustable to ensure that the second conveying mechanism 27 can deliver faulty battery cells into different first buffer layers 252.

[0110] Combination Figure 3 For example, the second conveying mechanism 27 is also provided with a first correction mechanism 271, which is used to correct abnormal battery cells, thereby ensuring that abnormal battery cells can accurately enter the first cache layer 252 in the first cache mechanism 25.

[0111] Optionally, the first correction mechanism 271 includes a plurality of first correction wheels, which are respectively disposed on both sides of the second conveying mechanism 27. The correction wheels limit the two sides of the abnormal battery cell, thereby correcting the abnormal battery cell.

[0112] See also Figure 3 The electrode grid line repair device 20 also includes a second buffer mechanism 26 and a third conveying mechanism. The second buffer mechanism is used to store the repaired good battery cells. The third conveying mechanism 28 is intersected with the first conveying mechanism 21 and is used to transfer the repaired good battery cells between the second buffer mechanism 26 and the first conveying mechanism 21.

[0113] Specifically, when the conveying of good battery cells on the production line is congested, the second conveying mechanism 27 can convey the repaired good battery cells on the first conveying mechanism 21 to the second buffer mechanism 26 for temporary storage, thus avoiding the blockage or stacking of good battery cells and ensuring the smooth operation of the electrode grid line repair device.

[0114] See Figure 7 In some embodiments, the second buffer mechanism 26 includes a second support frame 261, which has multiple second buffer layers 262 spaced apart in the height direction. Each second buffer layer 262 can hold one good battery cell, thus enabling the second buffer mechanism 26 to hold multiple good battery cells simultaneously. Correspondingly, the third conveying mechanism 28 is vertically adjustable to ensure that the third conveying mechanism 28 can deliver good battery cells into different second buffer layers 262.

[0115] Combination Figure 3 For example, the third conveying mechanism 28 is also provided with a second correction mechanism 281, which is used to correct the good battery cells so as to ensure that the good battery cells can accurately enter the second buffer layer 262 in the second buffer mechanism 26.

[0116] Optionally, the second alignment mechanism 281 includes multiple second alignment wheels, which are respectively arranged on both sides of the third conveying mechanism 28. The alignment wheels limit the two sides of the good battery cell, thereby realizing the alignment of the good battery cell.

[0117] Optionally, in some embodiments, the first conveying mechanism 21, the second conveying mechanism 27, the third conveying mechanism 28, and the fourth conveying mechanism 13 can all be conveyor belts. Further, a positioning sensor 211 is provided at each intersection of the first conveying mechanism 21 with the second conveying mechanism 27, the third conveying mechanism 28, and the fourth conveying mechanism 13. The positioning sensor 211 is used to detect whether a battery cell exists at the current position to ensure that the battery cell can be conveyed to the correct position.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
