Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic component detection, and more specifically, to a photovoltaic component detection device. Background Art

[0002] Photovoltaic modules are devices that use the photovoltaic effect to directly convert sunlight into electrical energy. Photovoltaic modules are composed of photovoltaic cells, packaging materials, backplanes, connectors and connectors. The packaging materials are used to protect photovoltaic cells from environmental factors. Photovoltaic tiles in photovoltaic modules are a product that combines roof tiles used in traditional buildings with photovoltaic technology. It is used to replace traditional roof materials and has the function of generating electricity, which can convert sunlight into electrical energy. In order to reduce light reflection losses and increase the transmittance of incident light, thereby improving the energy conversion efficiency of photovoltaic modules, a layer of anti-reflection film coating is set on the surface of the packaging materials used in photovoltaic tiles. In order to ensure that the packaging materials can still maintain an efficient and stable working state in various harsh environments, extend their service life, and reduce maintenance costs, testing equipment is required to test the corrosion resistance of the packaging materials during the production and processing process.

[0003] Since the packaging material used for photovoltaic tiles has an arc, in the prior art, a limiting tube is attached to the surface of the packaging material during detection, and then an acidic or alkaline detection reagent is placed in the limiting tube. A light transmitter is used to emit light through the packaging material, and the light emitted by the light transmitter is received by a light receiver. The position where the packaging material is covered with the detection reagent is continuously observed, and the changes in the surface of the anti-reflection film of the packaging material are observed. In order to more closely simulate the conditions that the packaging material may encounter in an actual environment, the detection reagent contained in the limiting tube is made to flow on the surface of the packaging material, and particulate impurities are added to the detection reagent to simulate sand in the air. When detecting the inclined curved surface of the photovoltaic tile, in order to avoid the change in the incident angle of the light beam emitted by the optical device passing through the detection reagent, resulting in a change in the propagation direction of the light beam in the liquid, which affects the clarity and accuracy of the imaging at the light receiving detection end, an anti-corrosion coating is provided on the surface of the light transmitter, and the detection reagent is made to submerge the light transmitter during detection.

[0004] However, since the detection reagent contains particulate impurities when flowing in the restriction tube, the disordered movement of the particulate impurities will damage the output end of the light transmitter, causing the quality of the light beam emitted by the light transmitter to decrease, affecting the quality of the light signal received by the light receiver, and resulting in inaccurate detection of the light transmittance and corrosion changes of the packaging material. Summary of the invention

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Refer to the instruction manual Figures 1 to 7 , a photovoltaic module testing device, comprising a testing box 1, a clamping mechanism 2 is arranged in the testing box 1, and the clamping mechanism 2 is used to clamp a component to be tested 8 and keep the component to be tested 8 in a horizontal state; A mobile driving mechanism 3 is arranged in the detection box 1, and a reagent coating mechanism 4 is arranged on the driving end of the mobile driving mechanism 3. The reagent coating mechanism 4 includes a limiting cylinder 41. The driving end of the mobile driving mechanism 3 is used to drive the limiting cylinder 41 to move and swing. A guide tube 1 45 and a guide tube 2 46 are fixedly arranged on the limiting cylinder 41. The discharge end of the guide tube 1 45 is arranged toward the bottom of the limiting cylinder 41. A circulation tube 49 is also arranged on the limiting cylinder 41. During detection, the limiting cylinder 41 and the surface of the component to be tested 8 are fitted to form a restriction. The guide tube 1 45 and the guide tube 2 46 are used to transport the detection reagent into the limiting cylinder 41. The circulation tube 49 is used to discharge the detection reagent in the limiting cylinder 41. The detection reagent flows and covers the surface of the component to be tested 8. The detection device also includes a detection component, which includes a light emitter 43 and a light receiver 6. The light emitter 43 is used to emit light to the component to be tested 8 covered with a detection reagent so that the light passes through the component to be tested 8. The light receiver 6 is used to detect the light passing through the component to be tested 8. The light emitter 43 is arranged in a limiting tube 41, and the detection reagent in the limiting tube 41 submerges the output end of the light emitter 43. The light receiver 6 is arranged below the component to be tested. The guide tube 1 45 is arranged vertically with the limiting tube 41, and the discharge end of the guide tube 1 45 faces the bottom of the limiting tube 41. The discharge end of the guide tube 2 46 is arranged obliquely in the limiting tube 41. A plurality of auxiliary tubes are fixedly arranged at the bottom end of the circulation tube 49, and the ends of the plurality of auxiliary tubes away from the bottom end of the circulation tube 49 are all fixedly connected to the limiting tube 41.

[0034] It should be noted that, since the surface of the component to be tested 8 is provided with an anti-reflection film coating, the corrosion resistance test of the anti-reflection film coating on the surface of the component to be tested 8 is carried out. In order to avoid meaningless damage to the edge of the anti-reflection film coating caused by the detection reagent, and only the upper surface of the component to be tested 8 is exposed to the environment, in order to reduce the production cost, only the upper surface of the component to be tested 8 is provided with an anti-reflection film coating, and damage to other film layers between the surface of the component to be tested 8 and the anti-reflection film coating is avoided. Therefore, for the corrosion resistance test, it is only necessary to place the detection reagent in the test area on the surface of the component to be tested 8 so that the detection reagent is in contact with the component to be tested 8, instead of immersing the component to be tested 8 in the detection reagent for testing; the detection reagent is a chemical reagent, which is used to simulate corrosive substances that may be encountered in the actual environment. Chemical reagents include but are not limited to acid solutions, alkali solutions, salt solutions and organic solvents, etc. Chemical reagents can also select corrosive substances higher than those that may be encountered in the actual environment to detect the corrosion resistance limit of the component to be tested 8. During detection, the limiting tube 41 is fitted with the surface of the component to be tested 8 to form a restriction, and a detection reagent is placed in the limiting tube 41 so that the detection reagent contacts the surface of the component to be tested 8, and the changes in the film surface of the packaging material are observed. In this way, the corrosion resistance of the anti-reflection film coating on the surface of the component to be tested 8 can be detected; a neutral liquid is placed in the limiting tube 41, and particulate impurities are added to the neutral liquid, and flow is generated between the liquid in the limiting tube 41 and the surface of the component to be tested 8, so that the scene of rainwater impacting the surface of the component to be tested 8 in a rainy day environment can be simulated, and the impact or friction resistance of the anti-reflection film coating on the surface of the component to be tested 8 can be detected by observing the changes in the film surface of the packaging material; a detection reagent is placed in the limiting tube 41, and the detection reagent contains particulate impurities, and flow is generated between the detection reagent in the limiting tube 41 and the component to be tested 8, and the changes in the film surface of the packaging material can detect whether the aging speed of the component to be tested 8 will be accelerated when encountering extreme environments, thereby shortening the overall service life. In order to improve the detection efficiency, three limiting cylinders 41 are prepared, and the above three situations are detected synchronously in different limiting cylinders 41, so as to realize the sampling detection of the batch of components 8 to be tested.

[0035] It should also be noted that the packaging material used for the component to be tested 8, i.e., the photovoltaic tile, is designed with a plurality of wavy bends in order to enhance the aesthetics, optimize the light receiving angle, and facilitate drainage. Therefore, the component to be tested 8 also has a plurality of wavy bends. During the detection, the detection reagent needs to be left on the surface of the component to be tested 8 for a period of time. During this period of time, the change in light passing through the film layer in the area can be used to determine the influence of the film layer. For example, the light emitter 43 can be a light source device that directly shines light on the surface of the component to be tested 8, and the light source can pass through the film layer and the component to be tested 8. The light receiver 6 can use a visual recognition unit, i.e., a visual detection camera, to regularly collect images formed by the light component passing through the component to be tested 8, and determine the image conditions, thereby obtaining the influence of the anti-reflection film layer in the area.

[0036] Furthermore, in order to prevent the surface of the detection reagent liquid in the limiting tube 41 from being unstable due to external vibrations, temperature changes or fluid movement, which makes it difficult to keep the liquid surface always perpendicular to the light emitted by the light emitter 43, the light emitter 43 is placed in the limiting tube 41 so that the liquid surface of the detection reagent in the limiting tube 41 submerges the light emitter 43 to avoid the above situation. The light beam emitted by the light emitter 43 is arranged parallel to the length direction of the limiting tube 41. The light receiver 6 includes an optical camera, which can regularly record the macroscopic changes on the surface of the part to be tested 8, such as color, glossiness, transparency, etc., and can compare the changes at different time points to evaluate the corrosion resistance and wear resistance. The detection end of the light receiver 6 can vertically receive the light beam emitted by the light emitter 43 through the part to be tested 8. The light receiver 6 can obtain high-quality images to avoid problems such as image distortion, overexposure or too dark, and blurred image edges. The light receiver 6 also includes a transmittance detector. The transmittance detector vertically receives the light beam emitted by the light emitter 43 through the part to be tested 8 and can detect the transmittance of the part to be tested 8.

[0037] It should also be noted that an exhaust pipe 1 is fixedly connected to the top of the limiting cylinder 41, and the top of the exhaust pipe 1 extends to the top of the limiting cylinder 41. The exhaust pipe 1 is used to exhaust the gas in the limiting cylinder 41. When the limiting cylinder 41 is tilted, the detection reagent inside it will not leak through the exhaust pipe 1.

[0038] The specific implementation scenario is as follows: the component to be tested 8 is clamped by the clamping mechanism 2 so that the component to be tested 8 is kept in a horizontal state, the box door set on the detection box 1 is closed, so that the detection box 1 is in a dark state, and the limiting cylinder 41 is driven to move by the driving end of the mobile driving mechanism 3, so that the limiting cylinder 41 contacts the surface of the component to be tested 8 to form a restriction, and then the detection reagent is input into the limiting cylinder 41 through the guide tube 1 45 and the guide tube 2 46. The detection reagent contains particulate impurities. As the detection reagent increases, the detection solution in the limiting cylinder 41 submerges the light emitter 43, which can prevent the light beam emitted by the light emitter 43 from passing through the incident angle of the detection reagent. Changes occur, causing the propagation direction of the light beam in the liquid to change. When the detection reagent fills the inner cavity of the limiting tube 41, the detection reagent in the limiting tube 41 is extracted through the circulation tube 49. The auxiliary tube can assist in increasing the flow rate of the detection reagent extracted from the limiting tube 41, so that a relative flow occurs between the detection reagent in the limiting tube 41 and the surface of the component to be tested 8. Then, the light source is emitted by the light emitter 43, and the light receiver 6 receives the light source emitted by the light emitter 43 through the component to be tested 8. According to the changes in the light source received by the light receiver 6, the corrosion resistance and wear resistance of the anti-reflection film coating on the surface of the component to be tested 8 are judged. By setting the guide tube 1 45 and the guide tube 2 46, the discharge end of the guide tube 1 45 is set toward the surface of the component to be tested 8, and the discharge end of the guide tube 2 46 is also inclined toward the component to be tested 8. The discharge end of the guide tube 1 45 and the discharge end of the guide tube 2 46 can not only enhance the impact force between the detection reagent and the component to be tested 8, but also more realistically simulate the impact between rainwater and the component to be tested 8 to improve the accuracy of detection. Compared with the prior art, by providing a guide tube 1 45 and a guide tube 2 46 with an inclined discharge end, the detection reagent discharged from the discharge ends of the guide tube 1 45 and the guide tube 2 46 to the limiting tube 41 is discharged by the circulation tube 49, and the liquid forms a stable flow direction and the impact force generated by the flow. Since the liquid flow direction is fixed, the impurity particles in the detection reagent in the limiting tube 41 will not move disorderly, and the impurities will not cause damage to the output end of the light emitter 43, thereby extending the service life of the light emitter 43 and ensuring that the quality of the light beam emitted by the light emitter 43 will not be affected, and the quality of the light signal emitted by the light emitter 43 received by the light receiver 6 will not be affected, and the detection of the light transmittance and corrosion changes of the packaging material is more accurate.

[0039] Refer to the instruction manual Figures 1 to 7In the process of corrosion resistance testing of the component 8 to be tested, in order to facilitate the continuous delivery of the testing reagent into the limiting cylinder 41 and to generate flow between the testing reagent in the limiting cylinder 41 and the component 8 to be tested, specifically, a positioning frame is fixedly provided on the limiting cylinder 41, a storage tank 42 is fixedly provided on the positioning frame, the storage tank 42 is located above the limiting cylinder 41, an annular hollow tube 44 is fixedly provided between the storage tank 42 and the limiting cylinder 41, and the top ends of the guide tube 1 45 and the guide tube 2 46 are both fixedly connected to the annular hollow tube 44. A pump 1 47 and a pump 2 48 are fixedly provided on the storage tank 42, the liquid inlet end of the pump 1 47 extends into the storage tank 42, the liquid discharge end of the pump 1 47 is fixedly connected to the annular hollow tube 44, the top end of the circulation pipe 49 is fixedly connected to the liquid inlet end of the pump 2 48, and the liquid discharge end of the pump 2 48 is fixedly connected to the storage tank 42.

[0040] It should be noted that gate valves are fixedly installed on the discharge end of the pump 1 47, the guide pipe 2 46 and the circulation pipe 49, and the gate valves include but are not limited to electromagnetic valves. The top of the storage tank 42 is fixedly connected to the exhaust pipe 2, and the top of the exhaust pipe 2 extends to the top of the storage tank 42. The exhaust pipe 2 connects the storage tank 42 with the outside.

[0041] It should also be noted that the storage tank 42 contains detection reagents. When the bottom of the limiting cylinder 41 is in contact with the surface of the component 8 to be tested, pump 47 is started, and the liquid inlet end of pump 47 draws the detection reagents in the storage tank 42, and the detection reagents enter the annular hollow tube 44 through the discharge end of pump 47. The detection reagents in the annular hollow tube 44 are discharged into the limiting cylinder 41 through guide tube 1 45 and guide tube 2 46. When the detection reagents in the limiting cylinder 41 are filled, pump 2 48 is started, and the liquid inlet end of pump 2 48 draws the detection reagents in the limiting cylinder 41, and pump 2 48 draws the detection reagents in the limiting cylinder 41 into the storage tank 42 through the circulation tube 49. The circulation of the detection reagents is realized through the cooperation of pump 1 47 and pump 2 48, so that the detection reagents can impact the component 8 to be tested, thereby simulating rainy days.

[0042] Refer to the instruction manual Figure 8 and Fig. 9, the guide tube 1 45 and the guide tube 2 46 cooperate to transport the detection reagent into the limiting tube 41, so that the detection reagent impacts the surface of the component to be tested 8 to simulate severe weather conditions such as rainy days. Since the detection reagent contains particulate impurities, during the process of the particulate impurities moving toward the component to be tested 8, if the light receiver 6 needs to periodically obtain the light emitted by the light transmitter 43 to detect the corrosion condition of the surface of the component to be tested 8, the particulate impurities in the light beam will form a light spot, resulting in inaccurate detection results. In order to solve the above problems, specifically, an impurity diffusion mechanism 7 is provided on the positioning frame, and the impurity diffusion mechanism 7 includes a rotating driver four 71, and the rotating driver four 71 is fixedly arranged on the positioning frame. A stirring head 72 is fixedly arranged on the output shaft of the rotating driver four 71, and the stirring head 72 is located in the limiting tube 41.

[0043] It should be noted that the rotary driver 71 is configured as a motor, and the stirring head 72 of the motor is fixedly disposed on the output shaft of the motor.

[0044] It should also be noted that before the light receiver 6 collects the light beam emitted by the light transmitter 43 at a fixed time, the pump 1 47 and the pump 2 48 are closed to stop the detection reagent in the limiting cylinder 41 from impacting the component to be tested 8, and the rotary driver 4 71 is started. The rotation of the output shaft of the rotary driver 4 71 drives the stirring head 72 to rotate. The rotation of the stirring head 72 applies force to the detection reagent. This force is transmitted to the surrounding liquid through the viscosity of the fluid, causing the liquid to start moving, thereby causing the detection reagent in the limiting cylinder 41 to form a "vortex". Since the detection reagent has a single flow direction in the limiting cylinder 41, the particulate impurities will move toward the inner wall of the limiting cylinder 41 under the action of gravity, so that the particulate impurities under the light transmitter 43 are removed. At this time, the light beam emitted by the light transmitter 43 can be received by the light receiver 6 to avoid the particulate impurities from affecting the detection results.

[0045] Refer to the instruction manual Figure 6 In order to improve the sealing effect between the limiting cylinder 41 and the component to be tested 8 during detection and prevent the detection reagent from leaking from the limiting cylinder 41, specifically, a flexible fitting component 411 is fixedly provided at the bottom of the limiting cylinder 41, and an auxiliary sealing component 412 is fixedly provided at the bottom edge of the limiting cylinder 41. The flexible fitting component 411 is located on the inner side of the auxiliary sealing component 412, and the flexible fitting component 411 is adapted to the auxiliary sealing component 412.

[0046] It should be noted that the flexible fitting component 411 and the auxiliary sealing component 412 are both configured to be silicone rubber. When the corrosion resistance test is performed on the component 8 to be tested, pressure is applied to the limiting cylinder 41 so that the bottom of the limiting cylinder 41 fits tightly with the surface of the component 8 to be tested.
