Description

Technical Field

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

[0002] A photovoltaic module is a device that directly converts solar light energy into electrical energy using the photovoltaic effect. A photovoltaic module is composed of components such as photovoltaic cells, encapsulation materials, backsheets, connectors, and connectors. The encapsulation materials are used to protect the photovoltaic cells from environmental factors. The photovoltaic tiles in a photovoltaic module are a product that combines traditional building roof tiles with photovoltaic technology. It is used to replace traditional roof materials and has the function of generating electricity, and can convert sunlight into electrical energy. In order to reduce light reflection loss and increase the transmittance of incident light, thereby improving the energy conversion efficiency of the photovoltaic module, an antireflection coating film is provided on the surface of the encapsulation material used for the photovoltaic tiles. In order to ensure that the encapsulation material can still maintain an efficient and stable working state in various harsh environments, extend the service life, and reduce the maintenance cost at the same time, a detection device is required to detect the corrosion resistance of the encapsulation material during the production and processing process.

[0003] Since the encapsulation material used for the photovoltaic tiles has a curvature, in the prior art, a limiting cylinder is attached to the surface of the encapsulation material during detection, and then an acidic or alkaline detection reagent is placed in the limiting cylinder. A light emitter emits light through the encapsulation material, and a light receiver receives the light emitted by the light emitter. Continuously observe the position of the encapsulation material covered with the detection reagent, and observe the change of the antireflection coating film surface of the encapsulation material. In order to more closely simulate the conditions that the encapsulation material may encounter in the actual environment, the detection reagent placed in the limiting cylinder is made to flow on the surface of the encapsulation material, and particulate impurities are added to the detection reagent to simulate sand grains in the air. When detecting the inclined curved surface of the photovoltaic tiles, in order to avoid the incident angle of the light beam emitted by the optical device passing through the detection reagent from changing, resulting in the change of the propagation direction of the light beam in the liquid and affecting the clarity and accuracy of the imaging of the light receiving detection end, an anti-corrosion coating is provided on the surface of the light emitter, and the detection reagent is made to submerge the light emitter during detection.

[0004] However, the detection reagent flows in the limiting cylinder. Since the detection reagent contains particulate impurities, the disorderly movement of the particulate impurities will damage the output end of the light emitter, resulting in a decrease in the quality of the light beam emitted by the light emitter, affecting the quality of the optical signal received by the light receiver, and causing the detection of the light transmittance and corrosion change of the encapsulation material to be inaccurate. Summary of the Invention

[0005] A photovoltaic module detection device provided by the present invention aims to solve the following problem: In existing photovoltaic module detection devices, when performing corrosion resistance detection on the encapsulation material of photovoltaic tiles, the detection reagent flows in the limiting cylinder. Since the detection reagent contains particulate impurities, the disorderly movement of the particulate impurities will damage the output end of the light emitter, resulting in a decline in the quality of the light beam emitted by the light emitter, affecting the quality of the optical signal received by the light receiver, and leading to inaccurate detection of the light transmittance and corrosion change of the encapsulation material.

[0016] In a preferred embodiment, the moving drive mechanism includes a mounting seat. The mounting seat is fixedly arranged on the inner wall of the detection box. A second rotation driver is fixedly arranged on the mounting seat. A first belt pulley is fixedly arranged on the output shaft of the second rotation driver.

[0018] The beneficial effects of the present invention are as follows:

[0019] By setting up a reagent coating mechanism, after the limiting cylinder contacts the surface of the component to be measured to form a limit, the detection reagent is sprayed on the component to be measured through the vertically arranged diversion pipe one and the obliquely arranged diversion pipe two. The detection reagent in the limiting cylinder is extracted through the circulation pipe, so that a stable flow direction is formed for the detection reagent in the limiting cylinder. The liquid flow direction is fixed, and the impurity particles in the detection reagent in the limiting cylinder will not move disorderly, and the impurities will not damage the output end of the light emitter, thereby prolonging the service life of the light emitter, and ensuring that the beam quality emitted by the light emitter will not be affected, the light signal quality received by the light receiver will not be affected, and the detection of the light transmittance and corrosion change of the packaging material is relatively accurate.

[0020] By setting up an impurity diffusion mechanism, the stirring head is driven to rotate by the output shaft of the rotary actuator four. The stirring head applies a force to the detection reagent in the limiting cylinder, and is transmitted to the surrounding liquid through the viscosity of the fluid, so that the liquid in the limiting cylinder begins to move. The particulate impurities will move towards the inner wall of the limiting cylinder under the action of gravity, so that the particulate impurities below the light emitter are moved away. At this time, the light beam emitted by the light emitter is received by the light receiver, avoiding the influence of particulate impurities on the detection result.

Detailed implementation manners

[0035] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non - essential improvements and adjustments to the present application according to the above application content.

[0036] Refer to the attached drawings of the specification Figures 1 to 7, a photovoltaic module detection device, including a detection box 1, in which a clamping mechanism 2 is arranged. The clamping mechanism 2 is used to clamp the component to be tested 8 and keep the component to be tested 8 in a horizontal state;

[0037] A moving drive mechanism 3 is arranged in the detection box 1. A reagent coating mechanism 4 is arranged on the drive end of the moving drive mechanism 3. The reagent coating mechanism 4 includes a limiting cylinder 41. The drive end of the moving drive mechanism 3 is used to drive the limiting cylinder 41 to move and swing. A first diversion tube 45 and a second diversion tube 46 are fixedly arranged on the limiting cylinder 41. The discharge end of the first diversion tube 45 faces 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 is attached to the surface of the component to be tested 8 to form a limit. The first diversion tube 45 and the second diversion tube 46 are used to convey the detection reagent into the limiting cylinder 41, and 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;

[0038] The detection device further includes a detection component. The detection component 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 the 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 the limiting cylinder 41, and the output end of the light emitter 43 is submerged by the detection reagent in the limiting cylinder 41. The light receiver 6 is arranged below the component to be tested. The first diversion tube 45 is perpendicular to the limiting cylinder 41, and the discharge end of the first diversion tube 45 faces the bottom of the limiting cylinder 41. The discharge end of the second diversion tube 46 is inclined and arranged in the limiting cylinder 41. A plurality of auxiliary tubes are fixedly arranged at the bottom end of the circulation tube 49, and one end of each of the plurality of auxiliary tubes far away from the bottom end of the circulation tube 49 is fixedly communicated with the limiting cylinder 41.

[0039] It should be noted that since an antireflection film coating is provided on the surface of the component 8 to be tested, in order to avoid meaningless damage to the edge of the antireflection film coating on the surface of the component 8 to be tested, and only the upper surface of the component 8 to be tested is exposed to the environment, and in order to reduce production costs, only the upper surface of the component 8 to be tested is provided with an antireflection film coating, and damage to other film layers between the surface of the component 8 to be tested and the antireflection film coating is also avoided. Therefore, for the corrosion resistance test, it is only necessary to place the test reagent in the test area on the surface of the component 8 to be tested so that the test reagent contacts the component 8 to be tested, rather than immersing the whole component 8 to be tested in the test reagent; the test reagent is a chemical reagent, and the chemical reagent is used to simulate corrosive substances that may be encountered in the actual environment. The chemical reagent includes, but is not limited to, acid solutions, alkali solutions, salt solutions, and organic solvents, etc. The chemical reagent can also be selected to be higher than the corrosive substances that may be encountered in the actual environment to detect the corrosion resistance limit ability of the component 8 to be tested. During the test, the limiting cylinder 41 is attached to the surface of the component 8 to be tested to form a limit, and the test reagent is placed in the limiting cylinder 41 so that the test reagent contacts the surface of the component 8 to be tested, and the change of the film surface of the encapsulating material is observed, so that the corrosion resistance of the antireflection film coating on the surface of the component 8 to be tested can be detected; a neutral liquid is placed in the limiting cylinder 41, particulate impurities are added to the neutral liquid, and a flow is generated between the liquid in the limiting cylinder 41 and the surface of the component 8 to be tested, so that the scenario of rainwater impacting the surface of the component 8 to be tested in a rainy environment can be simulated, and the change of the film surface of the encapsulating material is observed to detect the impact resistance or abrasion resistance of the antireflection film coating on the surface of the component 8 to be tested; a test reagent is placed in the limiting cylinder 41, and the test reagent contains particulate impurities, and a flow is generated between the test reagent in the limiting cylinder 41 and the component 8 to be tested, and the change of the film surface of the encapsulating material is observed to detect whether the component 8 to be tested will accelerate the aging speed in an extreme environment, resulting in a shortened overall service life. In order to improve the test efficiency, three limiting cylinders 41 are prepared, and the above three situations are synchronously tested in different limiting cylinders 41, so as to realize the sampling test of a batch of components 8 to be tested.

[0040] It should also be noted that the encapsulation material used for the component 8 to be tested, i.e., the photovoltaic tile, has multiple wavy bends in its shape design in order to enhance the aesthetic sense, optimize the light reception angle, and facilitate drainage. Therefore, the component 8 to be tested also has multiple wavy bends. When detecting, the detection reagent needs to stay on the surface of the component 8 to be tested for a period of time. Thus, within this period of time, by the change of the light passing through the film layer in this area, the affected situation of the film layer can be judged. For example, simply, the light emitter 43 can be a light source device that emits light directly onto the surface of the component 8 to be tested. The light can pass through the film layer and the component 8 to be tested, and the light receiver 6 can use a visual recognition unit, i.e., a visual detection camera, to periodically collect the images formed by the light passing through the component 8 to be tested and judge the image situation, so as to obtain the affected situation of the antireflection film layer in this area.

[0041] Furthermore, in order to avoid the instability of the liquid surface of the detection reagent in the limiting cylinder 41 due to factors such as external vibration, temperature change, or fluid movement, which may cause difficulty in keeping the liquid surface always perpendicular to the light emitted by the light emitter 43, the light emitter 43 is placed in the limiting cylinder 41 so that the liquid surface of the detection reagent in the limiting cylinder 41 submerges the light emitter 43, which can avoid the above situation. The light beam emitted by the light emitter 43 is arranged parallel to the length direction of the limiting cylinder 41. The light receiver 6 includes an optical camera, which can periodically record the macroscopic changes on the surface of the component 8 to be tested, 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 passing through the component 8 to be tested. The light receiver 6 can obtain high-quality images and avoid problems such as image distortion, overexposure or underexposure, and blurred image edges. The light receiver 6 also includes a light transmittance detector, and the light transmittance detector can detect the light transmittance of the component 8 to be tested by vertically receiving the light beam emitted by the light emitter 43 passing through the component 8 to be tested.

[0042] It should also be noted that an exhaust pipe 1 is fixedly connected to the top of the limiting cylinder 41, and the top end of the exhaust pipe 1 extends above the limiting cylinder 41. The exhaust pipe 1 is used to discharge the gas in the limiting cylinder 41, and the detection reagent inside the limiting cylinder 41 will not leak through the exhaust pipe 1 when the limiting cylinder 41 is tilted.

[0043] The implementation scenario is specifically as follows: The clamping mechanism 2 clamps the component 8 to be measured to keep the component 8 to be measured in a horizontal state. The door of the detection box 1 is closed to make the inside of the detection box 1 in a dark state. The driving end of the moving driving mechanism 3 drives the limiting cylinder 41 to move, so that the limiting cylinder 41 contacts the surface of the component 8 to be measured to form a limit. Then, the detection reagent is input into the limiting cylinder 41 through the first diversion tube 45 and the second diversion tube 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 avoid the change of the incident angle of the light beam emitted by the light emitter 43 passing through the detection reagent, resulting in the change of the propagation direction of the light beam in the liquid. When the detection reagent fills the inner cavity of the limiting cylinder 41, the detection reagent in the limiting cylinder 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 cylinder 41, so that a relative flow is generated between the detection reagent in the limiting cylinder 41 and the surface of the component 8 to be measured. Then, a light source is emitted by the light emitter 43, and the light receiver 6 receives the light source emitted by the light emitter 43 passing through the component 8 to be measured. According to the change of the light source received by the light receiver 6, the corrosion resistance and wear resistance of the antireflection film coated on the surface of the component 8 to be measured are judged. By arranging the first diversion tube 45 and the second diversion tube 46, the discharge end of the first diversion tube 45 is arranged facing the surface of the component 8 to be measured, and the discharge end of the second diversion tube 46 is also inclined and arranged facing the component 8 to be measured. The discharge end of the first diversion tube 45 and the discharge end of the second diversion tube 46 can not only enhance the impact force between the detection reagent and the component 8 to be measured, so as to more realistically simulate the impact generated between rainwater and the component 8 to be measured and improve the detection accuracy. Compared with the prior art, by arranging the first diversion tube 45 and the second diversion tube 46 with an inclined discharge end, the detection reagent discharged from the discharge end of the first diversion tube 45 and the discharge end of the second diversion tube 46 into the limiting cylinder 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 cylinder 41 will not move disorderly, and the impurities will not damage the output end of the light emitter 43, thus prolonging 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 optical signal received by the light receiver 6 from the light emitter 43 will not be affected, and the detection of the light transmittance and corrosion change of the packaging material is more accurate.

[0044] Refer to the attached drawings of the specification Figures 1 to 7During the process of performing the corrosion resistance test on the component 8 to be tested, in order to facilitate the continuous supply of the test reagent into the limiting cylinder 41 and cause the test reagent in the limiting cylinder 41 to flow with respect to the component 8 to be tested, specifically, a positioning frame is fixedly arranged on the limiting cylinder 41, and a storage tank 42 is fixedly arranged on the positioning frame. The storage tank 42 is located above the limiting cylinder 41. An annular hollow tube 44 is fixedly arranged between the storage tank 42 and the limiting cylinder 41. The tops of the first diversion tube 45 and the second diversion tube 46 are fixedly communicated with the annular hollow tube 44. A first pump 47 and a second pump 48 are fixedly arranged on the storage tank 42. The liquid inlet end of the first pump 47 extends into the storage tank 42, and the liquid discharge end of the first pump 47 is fixedly communicated with the annular hollow tube 44. The top of the circulation tube 49 is fixedly communicated with the liquid inlet end of the second pump 48, and the liquid discharge end of the second pump 48 is fixedly communicated with the storage tank 42.

[0045] It should be noted that gate valves are fixedly arranged on the liquid discharge end of the first pump 47, on the second diversion tube 46, and on the circulation tube 49. The gate valves include, but are not limited to, solenoid valves. The top of the storage tank 42 is fixedly communicated with a second exhaust pipe, and the top of the second exhaust pipe extends above the storage tank 42, so that the storage tank 42 is in communication with the outside.

[0046] It should also be noted that the storage tank 42 contains the test reagent. After the bottom of the limiting cylinder 41 is attached to the surface of the component 8 to be tested, the first pump 47 is started. The liquid inlet end of the first pump 47 extracts the test reagent in the storage tank 42, and the test reagent enters the annular hollow tube 44 through the liquid discharge end of the first pump 47. The test reagent in the annular hollow tube 44 is discharged into the limiting cylinder 41 through the first diversion tube 45 and the second diversion tube 46. After the limiting cylinder 41 is filled with the test reagent, the second pump 48 is started. The liquid inlet end of the second pump 48 extracts the test reagent in the limiting cylinder 41, and the second pump 48 extracts the test reagent in the limiting cylinder 41 back into the storage tank 42 through the circulation tube 49. The cooperation of the first pump 47 and the second pump 48 realizes the circulation of the test reagent, enabling the test reagent to impact the component 8 to be tested to simulate rain.

[0047] Refer to the attached instructions Figure 8 and Figure 9, the first diversion tube 45 and the second diversion tube 46 cooperate to deliver the test reagent into the limiting cylinder 41, so that the test reagent impacts the surface of the component to be tested 8 to simulate harsh climate conditions such as rainy days. Since the test reagent contains particulate impurities, when the particulate impurities move towards the component to be tested 8, if the light receiver 6 needs to regularly obtain the light emitted by the light emitter 43 to detect the corrosion condition of the surface of the component to be tested 8 at this time, the particulate impurities located in the light beam will form light spots, resulting in inaccurate test results. To solve the above problems, specifically, an impurity diffusion mechanism 7 is provided on the positioning frame. The impurity diffusion mechanism 7 includes a fourth rotation drive 71. The fourth rotation drive 71 is fixedly arranged on the positioning frame, and a stirring head 72 is fixedly arranged on the output shaft of the fourth rotation drive 71. The stirring head 72 is located inside the limiting cylinder 41.

[0048] It should be noted that the fourth rotation drive 71 is set as a motor, and the stirring head 72 of the motor is fixedly arranged on the output shaft of the motor.

[0049] It also should be noted that before the light receiver 6 regularly collects the light beam emitted by the light emitter 43, the first pump 47 and the second pump 48 are turned off to stop the impact of the test reagent in the limiting cylinder 41 on the component to be tested 8. The fourth rotation drive 71 is started, and the rotation of the output shaft of the fourth rotation drive 71 drives the stirring head 72 to rotate. The rotation of the stirring head 72 applies a force to the test reagent, and this force is transmitted to the surrounding liquid through the viscosity of the fluid, causing the liquid to start moving, and further forming a "vortex" in the test reagent in the limiting cylinder 41. Since the test reagent in the limiting cylinder 41 has a single flow direction, the particulate impurities will move towards the inner wall direction of the limiting cylinder 41 under the action of gravity, moving the particulate impurities below the light emitter 43 away. At this time, the light beam emitted by the light emitter 43 can be received by the light receiver 6, avoiding the influence of particulate impurities on the test results.

[0050] Refer to the attached Figure 6 , during the test, in order to improve the sealing effect between the limiting cylinder 41 and the component to be tested 8 and prevent the test reagent from leaking from the limiting cylinder 41, specifically, a flexible fitting component 411 is fixedly arranged at the bottom of the limiting cylinder 41, and an auxiliary sealing component 412 is fixedly arranged at the bottom edge of the limiting cylinder 41. The flexible fitting component 411 is located inside the auxiliary sealing component 412, and the flexible fitting component 411 is adapted to the auxiliary sealing component 412.

[0051] It should be noted that both the flexible fitting component 411 and the auxiliary sealing component 412 are made of silicone rubber. When performing a corrosion resistance test on the component to be tested 8, pressure is applied to the limiting cylinder 41 so that the bottom of the limiting cylinder 41 is in close contact with the surface of the component to be tested 8. At this time, the flexible fitting component 411 is in close contact with the component to be tested 8, and the auxiliary sealing component 412 is also in close contact with the component to be tested 8, achieving the effect of double sealing and preventing the leakage of the test reagent in the limiting cylinder 41.

[0052] Refer to the attached Figures 1 to 3 When performing a corrosion resistance test on the component to be tested 8, in order to stably clamp and position the component to be tested 8, specifically, two sets of clamping mechanisms 2 are provided. The two sets of clamping mechanisms 2 are respectively arranged on the inner walls of both sides of the test box 1. The clamping mechanism 2 includes a first linear driver 21. A first rotary driver 22 is fixedly arranged on the output end of the first linear driver 21. A pneumatic seat 28 is arranged on the output shaft of the first rotary driver 22. Two clamping seats 29 are slidably arranged on the pneumatic seat 28. The two corresponding clamping seats 29 clamp the component to be tested 8 by moving synchronously in opposite directions. A positioning plate 23 is fixedly arranged on the output shaft of the first rotary driver 22. A first rotating rod 24 and a second linear driver 26 are rotatably arranged on the positioning plate 23. A second rotating rod 25 is rotatably arranged on the first rotating rod 24. The output end of the second linear driver 26 is rotatably arranged with the second rotating rod 25.

[0054] It should also be noted that when the first linear driver 21 is started, the movement of the output end of the first linear driver 21 drives the first rotary driver 22 to move vertically, achieving the effect of adjusting the height of the pneumatic seat 28. When the first rotary driver 22 is started, the rotation of the output shaft of the first rotary driver 22 drives the positioning plate 23 to rotate, achieving the effect of adjusting the rotation of the pneumatic seat 28.

Place the component to be tested 8 between the two clamping seats 29, drive the two clamping seats 29 to approach each other, and the clamping seats 29 clamp the component to be tested 8.

[0055] In contrast to the horizontal clamping of the component 8 to be measured according to the wave bending designed for the component 8 to be measured in the above technical solution, the linear actuator two 26 is activated. The movement of the output end of the linear actuator two 26 drives the rotation of the first rotating rod 24. The rotation of the first rotating rod 24 cooperates with the rotation of the second rotating rod 25 to adjust the swing of the pneumatic seat 28, and then drives the two corresponding clamping seats 29 to approach each other. The edge of the component 8 to be measured is clamped by the clamping seat 29 according to the surface curvature of the component 8 to be measured.

Refer to Figure 13 , when the output shaft of the third rotating drive 35 rotates clockwise, the second moving seat 36 moves leftward on the first moving seat 34 from right to left; when the output shaft of the third rotating drive 35 rotates counterclockwise, the second moving seat 36 moves rightward on the first moving seat 34 from left to right.

[0058] It should also be noted that when the second rotating drive 32 is started, the rotation of the output shaft of the second rotating drive 32 drives the first pulley to rotate.

[0061] It should also be noted that the movement of the output end of the linear actuator four 5 drives the rotation actuator five to move horizontally, and the rotation of the output shaft of the rotation actuator five drives the light receiver 6 to swing horizontally, achieving the effect of adjusting the horizontal position and angle of the light receiver 6, which is beneficial for the collection end of the light receiver 6 to collect the light source emitted by the light emitter 43.
