Description

Technical Field

[0001] This invention relates to the field of photovoltaic power plant technology, specifically to a photovoltaic panel testing device for photovoltaic power plants. Background Technology

[0002] Photovoltaic panels, also known as solar panels, are core components that convert solar energy into electrical energy. They are mainly composed of solar cells made of semiconductor materials, tempered glass, EVA film, backsheet, and aluminum alloy frame. A photovoltaic power station is a complete power generation system that converts solar energy into electrical energy and achieves grid-connected or off-grid power supply. It mainly consists of a photovoltaic array composed of multiple photovoltaic panels, an inverter, a combiner box, a distribution cabinet, energy storage equipment, and a monitoring system. According to the installation scale and application scenario, it can be divided into centralized photovoltaic power stations, such as large-scale photovoltaic bases in deserts and Gobi, with a capacity of tens of megawatts or more, connected to the grid through high-voltage transmission lines, and distributed photovoltaic power stations, such as residential rooftops and industrial and commercial building rooftops, with a relatively small capacity, which can be used for self-consumption and surplus electricity can be fed into the grid. As a clean energy power generation project, photovoltaic power stations have the core advantages of zero emissions, zero pollution, and high renewable energy utilization efficiency. They do not consume fossil fuels and do not produce greenhouse gases or pollutants. They can effectively alleviate the problem of traditional energy shortages and help transform the energy structure, which is of great significance to promoting sustainable energy development. Currently, before installing photovoltaic panels in a photovoltaic power station, batches of photovoltaic panels need to be unpacked, positioned, tested for power-on, and screened for qualified products one by one. In the traditional mode, the packaging film on the surface of each photovoltaic panel needs to be removed manually. Not only is unpacking a single panel time-consuming, but manual labor is also susceptible to fatigue and operational proficiency, making it difficult to meet the batch testing requirements before the installation of large-scale power stations. As a result, the testing progress often lags behind the installation progress. Furthermore, after unpacking, the photovoltaic panels need to be manually transported to the testing station, and then the position of the photovoltaic panels needs to be manually adjusted to complete the power-on connection. The unpacking, transportation, positioning, and testing processes are independent of each other, which can easily lead to disconnection of processes, accumulation of workpieces, or waiting for testing. This not only further reduces the overall efficiency, but may also cause damage to the photovoltaic panels due to collisions during manual handling. Summary of the Invention

The third electric telescopic rod 515 is a small, high-precision servo electric telescopic rod, and its telescopic movement is controlled by the controller 2 to provide power for the movement of the telescopic frame 514. The telescopic rod's telescopic movement drives the telescopic frame 514 to move the shearing module 516 horizontally, achieving precise adjustment of the cutting position.

There are four second clamping modules 521, spaced apart from left to right at the bottom of the L-shaped frame 520. Each second clamping module 521 is electrically connected to the controller 2. The second clamping module 521 uses a small electric clamping claw made of soft silicone. Its clamping and releasing actions are controlled by the controller 2, providing a stable force point for the tearing action by evenly gripping the front and rear ends of the photovoltaic panel packaging film. The four second clamping modules 521 work together to ensure even force on the packaging film, preventing damage or residue during tearing. There are two fifth electric telescopic rods 522. The fifth electric telescopic rod 522 is installed at the bottom of the mounting bracket 518 and located outside the two second limit components 519 on the left and right.

[0022] More specifically, the delivery components include: a first guide rail frame 523, a lifting frame 524, a sixth electric telescopic rod 525, a slot seat 526, a second clamping module 521, and a fifth electric telescopic rod 522; there are two first guide rail frames 523, which are respectively installed in the vertical direction on the front and rear sides of the bottom inside the vertical housing 52; there are two lifting frames 524, which are respectively sleeved on the top of the front and rear first guide rail frames 523; there are two sixth electric telescopic rods 525, which are respectively installed in the vertical direction inside the vertical housing 52.

There are two fixtures, with two fixing frames 528 inserted into the inner side of two sets of slot seats 526 respectively.

The fixing frames 528 are made of customized stainless steel clamping frames, and the clamping surfaces are pasted with silicone pads to avoid scratching the edges of the photovoltaic panels. In cooperation with the slot seats 526, under the drive of the seventh electric telescopic rods 527, the photovoltaic panels in the stack except for the bottom one are clamped and fixed in opposite directions. In conjunction with the sixth electric telescopic rod 525, the lifting frame 524 is lifted upward to realize the separation of the bottom single photovoltaic panel, ensuring the continuity and stability of single panel transportation.

[0023] The specific tasks are as follows: Step 1: After the outer packaging of the photovoltaic panels has been initially removed, the stacks are neatly placed on the surface of the horizontal roller conveyor line 51 of the pre-processing mechanism. Then, the controller 2 is activated. According to the built-in preset program, the controller 2 simultaneously activates the horizontal roller conveyor line 51, the distribution components inside the vertical housing 52, the lifting roller conveyor line 53, and the large dual-axis moving platform 55, initiating subsequent automated operations. After the horizontal roller conveyor line 51 is activated, it conveys the stack of photovoltaic panels to the left until the entire stack enters the inner area of ​​the vertical housing 52. The two sixth electric telescopic rods 525 work in tandem, extending or shortening to drive the corresponding lifting frame 524, which slides up and down along the outer side of the first guide rail 523, adjusting the lifting frame 524 to a specified height. This height must ensure that the fixing frame 528 inside the lifting frame 524 avoids the bottom panel and aligns with the front and rear sides of the second photovoltaic panel from the bottom. The seventh electric telescopic rods on the front and rear sides... The telescopic rod 527 extends synchronously, driving the corresponding fixing frame 528 to move towards the center along the inner side of the slot seat 526, thus clamping and fixing the upper photovoltaic panel. Then, the sixth electric telescopic rod 525 extends again, driving the lifting frame 524 and the fixed upper photovoltaic panel to lift upward as a whole. At this time, only the bottom one of the photovoltaic panels in the stack remains on the horizontal roller conveyor line 51. Then, the horizontal roller conveyor line 51 continues to start, conveying the bottom unclamped photovoltaic panel to the surface of the lifting roller conveyor line 53 to complete the single-panel separation operation. The lifting structure inside the lifting roller conveyor line 53 starts, lifting the single photovoltaic panel on the surface of its conveyor roller to the preset height, ensuring that the film-tearing component can accurately align with the packaging film. The large dual-axis moving platform 55 starts, driving the mounting top plate 56 below its moving end, along with the entire set of film-tearing components below the mounting top plate 56, to move to the designated position directly above the lifted photovoltaic panel, waiting for the subsequent film-tearing operation. Step 2: Controller 2 continues to activate the fourth electric telescopic rod 517, the fifth electric telescopic rod 522, the second clamping module 521, the mini electric telescopic rod 511, the second electric telescopic rod 59, the third electric telescopic rod 515, the shearing module 516, and the handling device 3 through a preset program. The fourth electric telescopic rods 522 on both the front and rear sides start synchronously, driving their respective connected mounting brackets 518 to move downwards to a specified height, so that the L-shaped frame 520 below the mounting bracket 518 fits against the front and rear outer sides of the photovoltaic panel. The two fifth electric telescopic rods 522 shorten synchronously. Under the guiding and limiting action of the second limiting component 519, the L-shaped frame 520 moves inwards, so that the four sets of second clamping modules 521 at the bottom of the L-shaped frame 520 align with the photovoltaic panel package. The front and rear ends of the packaging film are gripped firmly by the second clamping module 521, providing a stable force point for the subsequent tearing action. The micro electric telescopic rod 511 extends, driving the suction cup 512 to move downward until it contacts the top center of the photovoltaic panel packaging film. Then, the suction cup 512 activates its vacuum adsorption function, generating a stable vacuum suction force to adsorb the top of the packaging film. Then, the micro electric telescopic rod 511 shortens simultaneously, driving the suction cup 512 to move upward, pulling the top center of the packaging film upward to form a raised force point. At the same time, the second electric telescopic rods 59 on both the front and rear sides shorten simultaneously, driving the top of the connecting rod 510 at the corresponding position to rotate outward. The bottom end of the connecting rod 510 is fixedly connected to the clamping seat 58, and the clamping seat 58 is connected to the mounting frame 57 via a rotating shaft seat. Therefore, the connecting rod 510 will drive the clamping seat 58 to rotate inward around the rotating shaft connection point, ultimately making the front and rear clamping seats 58 precisely align with the front and rear sides of the bottom of the packaging film pulled up below the suction cup 512. Secondary fixation is completed through opposing clamping actions to prevent the packaging film from shifting during subsequent cutting. The third electric telescopic rod 515 extends, driving the telescopic frame 514 to move horizontally to the left along the inner side of the slot frame 513, thereby driving the cutting module 516 at the left end of the telescopic frame 514 to move to the left until the cutting module 516 reaches the packaging film area between the suction point below the suction cup 512 and the clamping point of the clamping seat 58. The cutting module 516 is then activated. A horizontal cut is made in the packaging film of this area. After the cut, the fifth electric telescopic rods 522 on both the front and rear sides extend synchronously, driving the second clamping module 521 to move forward and backward to tear the packaging film cut in the middle to both sides, so that the top of the packaging film is completely broken and detached from the photovoltaic panel body. The large dual-axis moving platform 55 drives the film tearing component to reset and move away as a whole to avoid interfering with subsequent handling actions. The telescopic structure inside the handling equipment 3 is activated, driving its execution end to move above the photovoltaic panel. The photovoltaic panel on the surface of the lifting roller conveyor line 53 is grabbed by vacuum adsorption and transferred to the working area of ​​the detection mechanism 4. The large dual-axis moving platform 55 drives the installation top plate 56 and the film tearing component below it to move to the surface of the lifting roller conveyor line 53.The vacuum adsorption function of suction cup 512 is used to adsorb and grab residual packaging film fragments on the surface of the conveyor line, and then transfer them to a designated collection area outside the equipment for centralized processing, so as to avoid residual film fragments affecting the operation of subsequent equipment or the accuracy of testing; Step 3: The controller 2's internal pre-programmed control system starts the first positioning module 42, the second positioning module 43, the first motor 413, the mounting base 410, the miniature dual-axis moving module 414, the double-end moving platform 47, the cutting robotic arm 48, the clamping robotic arm 49, the first clamping module 418, the first electric telescopic rod 417, the detection plug 416, the lifting suction cup module 46, and the lifting conveyor 6. The handling equipment 3 smoothly places the photovoltaic panel on the surface of the two sets of fixed suction cups 45 on the left and right. The two sets of first positioning modules 42 on the left and right and the two sets of second positioning modules 43 on the front and back start synchronously. Through mechanical positioning, the edge position of the photovoltaic panel is accurately positioned to ensure that the photovoltaic panel is in the correct position. At the reference position of the detection, the clamping mechanisms of the first positioning module 42 and the second positioning module 43 are activated to clamp the edge of the photovoltaic panel. At the same time, the fixed suction cup 45 activates the vacuum adsorption function to adsorb and fix the bottom of the photovoltaic panel. The first motor 413 of the docking parts on the front and rear sides starts synchronously, driving the belt assembly 412 at the corresponding position to rotate. The drive wheel of the belt assembly 412 rotates under the drive of the first motor 413, and works with the driven wheel to realize the circumferential movement of the belt. Since the belt is fixedly connected to the limiting end of the first limiting component 411, the rotation of the belt will drive the miniature dual-axis moving module 414 to move horizontally to the connection on both sides below the photovoltaic panel under the constraint of the first limiting component 411. At the wire connector location, the miniature dual-axis moving module 414 drives the mounting plate 415 at its bottom to perform dual-axis fine-tuning in the front-back and vertical directions, so that the first clamping module 418 below the mounting plate 415 comes into contact with the wire connector. The dual-end moving platform 47 is activated, driving the cutting robotic arm 48 on its left moving end and the clamping robotic arm 49 on its right moving end to move sequentially to the designated position below the photovoltaic panel. The execution end of the cutting robotic arm 48 is activated to cut and remove the transport strap wrapped around the outside of the connecting wire at the bottom of the photovoltaic panel. The clamping robotic arm 49 is activated to organize and lay out the connecting wire after the strap is removed to avoid tangling, and moves the terminal end to the first clamping position. Inside module 418; the first clamping module 418 is activated to clamp and fix the terminal, completing the transfer and positioning of the terminal. The first electric telescopic rod 417 is shortened, driving the first clamping module 418 to move to the left, thereby driving the terminal to be accurately inserted into the inside of the detection plug 416. The detection plug 416 is activated, and by power-on detection, it determines whether there are faults such as open circuits or short circuits in the internal circuit of the photovoltaic panel, and transmits the detection data to the controller 2 in real time. The controller 2 will analyze and process the data to generate the detection results. After the detection is completed, the fixed suction cup 45 stops vacuum adsorption, and the first positioning module 42 and the second positioning module 43 release the clamping and fixing of the photovoltaic panel.Subsequently, the lifting suction cup module 46 is activated, its suction cups adsorbing and fixing the bottom of the photovoltaic panel. The lifting structure of the lifting suction cup module 46, with the assistance of the suction cups, lifts the photovoltaic panel upwards to a designated height. Afterwards, the lifting suction cup module 46 stops adsorbing, and the conveying device 3 restarts, grabbing the photovoltaic panel lifted to the designated height and transferring it to the internal transfer end of the lifting conveyor 6. The lifting conveyor 6 starts, adjusting its height through its own lifting structure, and in conjunction with the telescopic conveying structure, moves the inspected photovoltaic panel to a designated position outside the outer casing 1.
