Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic cell processing, specifically, it relates to an integrated battery string stack rework platform. Background Technology

[0002] Crystalline solar panels are devices that convert solar energy into electrical energy using the photovoltaic effect. Also known as photovoltaic solar panels, they typically consist of multiple photovoltaic cells that absorb sunlight and convert it into direct current (DC) electricity. These panels can be installed on building rooftops, the ground, or other suitable areas to generate or supply electricity. As an important means of clean energy generation, photovoltaic solar panels are receiving increasing attention and widespread application. Globally, governments and businesses are investing in photovoltaic power generation projects to reduce dependence on traditional fossil fuels, decrease environmental pollution, and promote sustainable development.

[0003] In the processing of crystalline solar cells, it is usually necessary to inspect the battery strings with attached busbars to ensure they are up to standard. If any defective (NG) products are found, they need to be reworked to improve the yield. Currently, the inspection of battery strings with attached busbars is typically done manually, with rework only for those that fail inspection. Manual inspection is inefficient, prone to battery string accumulation, and lacks accuracy, posing a risk of missed or false inspections. Therefore, this invention provides an integrated battery string stacking and rework platform. Utility Model Content

[0004] To address the aforementioned issues, this invention provides an integrated battery string stack rework station, which can automatically identify non-compliant (NG) products in the battery string and transfer them to the rework station for inspection. Simultaneously, it can stack NG products during the inspection process, thereby improving automation integration and work efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] An integrated battery string stacking rework station includes a battery string conveyor belt, a camera detection module, a rework moving module, a rework platform, and a stacking elevator. The camera detection module is located above the battery string conveyor belt, the rework platform is located to the side of the battery string conveyor belt, the rework moving module is located between the battery string conveyor belt and the rework platform, and the stacking elevator is located to one side of the battery string conveyor belt.

[0007] As a preferred technical solution, it also includes multiple correction modules, which are respectively disposed on both sides of the battery string conveyor belt.

[0008] As a preferred technical solution, the system also includes a frame, in which the battery string conveyor belt, the alignment module, the camera detection module, the rework moving module, the rework table, and the stacking elevator are all housed.

[0009] As a preferred technical solution, the battery string conveyor belt is configured as two four-segment conveyor belts.

[0010] As a preferred technical solution, the camera detection module includes a first CCD camera, a second CCD camera, and a third CCD camera.

[0011] As a preferred technical solution, the rework mobile module includes a motor linear guide, a guide rail, a support plate, and a transport body. The support plate is drivenly connected to the motor linear guide and slidably connected to the guide rail. There are three sets of transport bodies, all of which are mounted on the support plate. Each set of transport bodies consists of a support column, a lifting cylinder, and a lifting plate. The three sets of transport bodies are respectively positioned within the gaps between the two four-section conveyor belts.

[0012] As a preferred technical solution, the rework station includes a workbench, and the workbench is provided with a transport clearance groove.

[0013] As a preferred technical solution, the stacking elevator includes a stepper motor, a transmission belt, a support frame, and a stacking bracket. The stepper motor is connected to the stacking bracket via the transmission belt. The support frame has slide rails on both sides, and the stacking bracket is slidably connected to the slide rails. The stacking bracket has several stacking columns, and a stacking position is formed between two adjacent stacking columns. The stacking position is located in the gap between the two four-segment conveyor belts.

[0014] As a preferred technical solution, the stacker lifter is provided with 20 stack positions. Beneficial effects

[0015] This invention uses a battery string conveyor belt to transport battery strings with attached busbars. When the battery strings are transported to the camera detection module, the camera detection module takes pictures for inspection. If the battery strings are found to be qualified, they are transported out along the battery string conveyor belt. If the battery strings are found to be defective (NG), the rework moving module transfers the NG battery strings to the rework station for manual inspection. During the inspection, the battery string conveyor belt and the camera detection module continue to work. If NG battery strings are found again, they are stacked by a stacking elevator. After the rework station has completed its inspection, the rework moving module transfers the stacked NG battery strings from the stacking elevator to the rework station for further inspection. This invention achieves automatic identification of NG battery strings and transfers them to the rework station for inspection. At the same time, NG battery strings can be stacked during the inspection process, improving the degree of automation integration and work efficiency. Attached Figure Description

[0025] Please refer to Figures 1 to 4 , the present utility model provides an integrated battery string stacking and rework table. Please refer to Figure 1 , which includes a battery string conveyor belt 1, a camera detection module 2, a rework moving module 3, a rework table 4, and a stack hoist 5. The camera detection module 2 is arranged above the battery string conveyor belt 1, the rework table 4 is arranged on the side of the battery string conveyor belt 1, the rework moving module 3 is arranged between the battery string conveyor belt 1 and the rework table 4, and the stack hoist 5 is arranged on one side of the battery string conveyor belt 1.

[0026] During operation, the battery string conveyor belt 1 conveys the battery string with the bus bar pasted. When it is conveyed below the camera detection module 2, the camera detection module 2 takes pictures for detection. If the battery string is detected to be qualified, it is conveyed out along the battery string conveyor belt 1. If the battery string is detected as a NG product, the rework moving module 3 transfers the NG product battery string to the rework table 4 for manual inspection. During the inspection process, the battery string conveyor belt 1 and the camera detection module 2 continue to work. If the battery string is detected as a NG product again, the stack hoist 5 stacks it. After the rework table 4 finishes the inspection, the rework moving module 3 transfers the NG product battery string stacked in the stack hoist 5 to the rework table 4 for continuous inspection.

[0027] Specifically, it also includes multiple correction modules 6, which are respectively disposed on both sides of the battery string conveyor belt 1. The correction modules 6 can correct the battery string when it enters the battery string conveyor belt 1, so as to facilitate the detection by the camera detection module 2.

[0028] In one embodiment, to achieve alignment of the battery string, the alignment module 6 may include an alignment cylinder 61, an alignment roller 62, and a roller fixing plate 63. The cylinder shaft of the alignment cylinder 61 is connected to the roller fixing plate 63, and the alignment roller 62 is connected to the roller fixing plate 63 via a rotating shaft or the like. The alignment module 6 uses the alignment cylinder 61 to drive the alignment roller 62 to move towards or away from the battery string conveyor belt 1, thereby achieving alignment of the battery string.

[0029] Specifically, it also includes a frame 100, within which the battery string conveyor belt 1, the alignment module 6, the camera detection module 2, the rework moving module 3, the rework table 4, and the stacking elevator 5 are all housed. The frame 100 serves to support the installation and provides centralized control. The battery string conveyor belt 1, the alignment module 6, the camera detection module 2, the rework moving module 3, the rework table 4, and the stacking elevator 5 can be fixed to the frame 100 using screws or other methods; the fixing method is not specifically limited.

[0030] Specifically, please refer to Figure 2 The battery string conveyor belt 1 is configured as two four-segment conveyor belts 11. It should be noted that the battery string itself is quite long. By using two four-segment conveyor belts, the battery string is supported and transported across the two conveyor belts. Each four-segment conveyor belt has three gaps, and during testing, the battery string longitudinally crosses these three gaps, ensuring smooth transport. The presence of these three gaps in the four-segment conveyor belts facilitates the subsequent installation of three sets of handling bodies 34 and stacking positions 56 on the stacking bracket 53. It should be noted that each complete conveyor belt consists of four smaller segments, with gaps between each segment. The conveyor belts 11 are driven by a motor to move the belt, thereby achieving the transport of the battery string.

[0031] Specifically, the camera detection module 2 includes a first CCD camera, a second CCD camera, and a third CCD camera. By taking pictures with the three sets of CCD cameras and comparing the pictures with preset positions, it can be determined whether the busbar laying position on the battery string meets the requirements. If it does not meet the requirements, it is judged as an NG product.

[0032] The first, second, and third CCD cameras are all existing CCD cameras, and their structures, working principles, and control methods are all existing technologies. The first, second, and third CCD cameras can all be fixed to the frame 100 using mounting brackets or similar means.

[0033] Specifically, please refer to Figure 2 The rework mobile module 3 includes a motor linear guide rail 31, a guide rail 32, a support plate 33, and a transport body 34. The support plate 33 is drive-connected to the motor linear guide rail 31 and slidably connected to the guide rail 32. Three sets of transport bodies 34 are provided, each set mounted on the support plate 33. Each set of transport bodies 34 consists of a support column 35, a lifting cylinder 36, and a lifting plate 37, and is respectively positioned within the gap between the two four-section conveyor belts 11. The support column 35 is fixed to the support plate 33 by screws, etc. The lifting cylinder 36 is fixed to the support column 35 and connected to the lifting plate 37, driving the lifting plate 37 to rise and fall. During operation, the motor linear guide rail 31 drives the support plate 33 to move back and forth on the guide rail 32, and the battery strings are transported by the rising and falling of the transport bodies 34. When a defective battery string is detected, the lifting cylinders 36 of the three sets of transport bodies 34 located in the three gaps of the four-section conveyor belt start working, causing the lifting plate 37 to rise and lift the defective battery string. Then, the motor linear guide 31 starts to transfer the lifting cylinders 36 and the lifting plate 37 on the support plate 33 to the rework table 4. The battery string is transferred to the rework table 4 along with the lifting plate 37. Then, the lifting cylinders 36 lower the lifting plate 37, and the battery string is placed on the rework table 4 for inspection. The motor linear guide 31 is a linear guide driven by a motor or an integrated motor to achieve linear drive.

[0034] Specifically, the rework station 4 includes a workbench, on which a transport clearance groove is provided. The purpose of the transport clearance groove is to allow the three transport bodies 34 to pass each other when they pass the workbench and to facilitate the three transport bodies 34 to place the battery string onto the workbench.

[0035] Specifically, please refer to Figure 3The stacking lifting machine 5 includes a stepper motor 57, a transmission belt 51, a support frame 52, and a stacking bracket 53. The stepper motor 57 is connected to the stacking bracket 53 via the transmission belt 51. The support frame 52 has slide rails 54 on both sides, and the stacking bracket 53 is slidably connected to the slide rails 54. The stacking bracket 53 has several stacking posts 55, with a stacking position 56 formed between two adjacent stacking posts 55. The stacking position 56 is located within the gap between the two four-segment conveyor belts 11. It should be noted that the stacking bracket 53 has three rows of stacking posts 55, corresponding to the three gaps of the four-segment conveyor belts. The same horizontal position of the three rows of stacking posts 55 forms a stacking position 56, which is used to stack one string of defective batteries. When the rework station 4 is working, the rework moving module 3 no longer transfers NG battery strings to the rework station 4. At this time, the stacking elevator 5 performs stacking. The stacking position 56 itself overlaps with the three gaps, that is, the NG battery strings are between two adjacent stacking columns 55. At this time, the stepper motor 57 drives the transmission belt 51 to move, which in turn drives the stacking support 53 to lift and stack the NG battery strings. After being lifted, the next stacking position 56 automatically overlaps with the three gaps. When the next battery string enters the inspection, if an NG product is found, the above steps are repeated to stack the batteries.

[0036] In this embodiment, the stacking elevator 5 is provided with 20 stacking positions 56. After the battery string at the maintenance station is maintained, an instruction is sent to transfer the NG battery string from the stacking elevator to the maintenance station 4 for continued maintenance. The stacking elevator 5 then performs an adaptive descent.

[0037] The above structure enables the present invention to automatically identify non-compliant (NG) products in the battery string and transfer them to the rework station 4 for inspection. At the same time, NG products can be stacked during the inspection process, which improves the degree of automation integration and work efficiency.

[0038] This utility model is not limited to the above-described embodiments. If any modifications or variations of this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims of this utility model and equivalent technologies, this utility model also includes such modifications and variations.
