Description

Technical Field

[0001] This utility model relates to the field of optical material performance testing technology, specifically a solar panel light refractive index tester. Background Technology

[0002] Solar panels, also known as solar cell modules, are thin photovoltaic semiconductor wafers that directly generate electricity using sunlight. They are typically assembled from several solar cells on a single panel and are the core component of a solar power system. Tempered glass is usually installed on the outside of the solar cell module to protect the cells. Since solar panels operate based on the photoelectric effect, the tempered glass must have high light transmittance during manufacturing. Therefore, a solar panel refractive index tester is used to measure the refractive index of the tempered glass. The main purpose is to evaluate its ability to refract and capture light, thereby optimizing the efficiency of the solar panel. Because the refractive index reflects the solar panel material's ability to refract light, various tests allow for the selection of materials with suitable refractive indices to ensure the quality and performance stability of the solar panel products. Therefore, a solar panel refractive index tester is an indispensable instrument in modern solar panel production.

[0003] Existing light refractive index testers mainly consist of a refractive prism holder and a light-entry prism holder. The tempered glass sample is placed on the surface of the refractive prism holder, and the light-entry prism holder is moved downwards to fix the sample for testing. Generally, a light-shielding plate is rotatably connected to the side wall of the light-entry prism holder. During testing, the light-shielding plate is rotated and raised to open the light-transmitting prism, allowing the sample to receive light. However, a slight loosening can occur at the connection between the light-shielding plate and the light-entry prism holder, and the bottom of the light-shielding plate is suspended after movement. Therefore, during testing, collisions during operation can easily cause the light-shielding plate to slide downwards, partially blocking the light-transmitting prism and affecting the stability of light reception by the light-transmitting prism, as well as the accuracy of the light refractive index test. Utility Model Content

[0004] The purpose of this invention is to provide a solar panel light refractive index tester to solve the problem mentioned in the background art that after long-term use, the connection between the light-shielding plate and the light-incoming prism seat will become slightly loose, and the bottom of the light-shielding plate will be suspended after it is moved. Therefore, during the testing process, the light-shielding plate is prone to sliding down due to collisions during operation, causing the light-shielding plate to partially block the light-transmitting prism, affecting the stability of the light-transmitting prism's light reception and the accuracy of the light refractive index test.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solar panel light refractive index tester, which is used to be installed above the main body of the tester, including a sample testing part, a support part, and a light-shielding part.

[0013] Preferably, there are two sets of mounting slots, which are symmetrically distributed on the vertical central axis of the connecting frame. Each set of mounting slots contains several sets of No. 1 telescopic rods.

[0014] By adopting the above technical solution, the opening of the mounting groove facilitates the lateral movement of the connecting plate inside it.

[0015] Preferably, two sets of fixing slots are provided on each of the two inner sidewalls of the support frame. The two sets of fixing slots are symmetrically distributed on the transverse central axis of the support frame. The end of the plug block away from the connecting plate is inserted into the interior of the fixing slot and is in close contact with the inner sidewall of the fixing slot.

[0016] By adopting the above technical solution, the plug-in block can be initially fixed when it is inserted into the fixed slot.

[0017] Preferably, sliding grooves are provided on both inner sidewalls of the support frame. The sliding grooves are located below the fixed slots. A sliding connecting block is slidably disposed on the inner side of the sliding groove. The portion of the sliding connecting block away from the sliding groove extends to the outer side of the light-shielding plate and is fixedly connected to the outer sidewall of the light-shielding plate.

[0018] By adopting the above technical solution, the stability of the light-shielding plate when sliding up and down is improved.

[0019] Preferably, two sets of buffer grooves are provided on the top and bottom surfaces of the support frame body. The two sets of buffer grooves are symmetrically distributed on the vertical central axis, and a second telescopic rod is slidably connected to the inner sidewall of each set of buffer grooves.

[0022] By adopting the above technical solution, when the light-shielding plate is attached and fixed upwards or downwards, it can play a buffering role, effectively reducing the vibration force generated by the collision between the light-shielding plate and the support frame.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] (1) By squeezing the two sets of anti-slip side plates, the push plate moves closer to each other. The push plate moves the connecting plate laterally inside the mounting slot. The connecting plate moves the plug block out of the fixed slot, releases the limiting measures on the light shield and pushes the light shield upward, opening the inside of the light-transmitting prism. At this time, the magnet magnetically attracts the connecting iron plate, causing the light shield to be tightly attached to the inner wall of the support frame. Then, the squeezing force on the push plate is released, the cylindrical spring stops being stressed and stretches outward to reset, and the reset pushing force is applied to the connecting plate. The cylindrical spring pushes the end of the plug block into the inside of the fixed slot, thus forming a light shield that is easy to fix quickly. By the attraction function of the magnet on the connecting iron plate, an auxiliary pushing force is applied to the moving light shield, which has the advantages of convenient and quick operation. At the same time, the top and sides of the light shield are limited and fixed, which increases the stability of the light shield after it is raised, reduces the problem of the light shield sliding down and blocking the light, improves the stability of the light-transmitting prism in receiving light, and improves the accuracy of the light refractive index test.

[0027] (2) By setting buffer structures on the top and bottom surfaces inside the support frame, when the light shield moves upward, the magnet attracts the connecting iron sheet, causing the light shield to collide and stick tightly with the inner wall of the support frame. The top surface of the light shield contacts the damping block, pushing the damping block to move toward the inside of the buffer groove and applying pressure to the buffer spring and the second telescopic rod. Through the cooperation of the buffer spring and the damping block, the upward force of the light shield is elastically buffered. Thus, when the light shield sticks and adheres to the inner wall of the support frame, the vibration force generated between the light shield and the support frame can be effectively reduced, thus having a buffering effect.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0038] Example 1

[0039] Please see Figure 1-7 This embodiment provides a technical solution for a solar panel light refractive index tester: A solar panel light refractive index tester is used to be installed above the tester body 1, including a sample testing part 2, a support part 3, and a light-shielding part 4. All the equipment of the refractive index tester is connected to an external power supply through a power line and connected to a control terminal on the outer wall of the tester body 1 through a data line. Multiple sets of adjustment scale rings are provided on the outer wall of the tester body 1 to control the internal structure of the tester body 1 for adjustment, adjusting the various components of the tester body 1 to align with the light source. A digital display screen is also provided on the outer wall of the refractive prism seat 201 to record the refractive index of the light after passing through the tempered glass sample in the solar cell module. The transmittance of the tempered glass sample is measured by the refractive index data.

[0040] The refractive prism holder 201 and the light-gathering prism holder 202 provide the structural basis for placing and fixing the tempered glass sample. The light-transmitting prism 203 can receive and transmit light, while the reflector 204 reflects light. This scheme enables light to propagate around the sample along a predetermined path, thereby accurately measuring the refraction of light after passing through the tempered glass sample and comprehensively evaluating the optical performance of the sample.

[0041] The support part 3 provides a stable support structure for the light-shielding part 4. The support frame 301 is connected to the main body 1 of the tester through the support rod 302, ensuring the overall stability. The design of the fixed slot 303 and the sliding groove 304 can not only perform initial positioning of the light-shielding plate 401 (the plug block 408 is inserted into the fixed slot 303), but also ensure the smoothness of the light-shielding plate 401 when sliding up and down (the sliding connecting block 409 slides in the sliding groove 304). The magnet 305 magnetically attracts the connecting iron piece 410 on the light-shielding plate 401, further fixing the position of the light-shielding plate. The buffer structure composed of the second telescopic rod 307, the buffer spring 308 and the damping block 309 in the buffer groove 306 plays a buffering role during the movement of the light-shielding plate, reducing the collision and vibration between the light-shielding plate and the support frame, protecting the equipment components, and improving the stability of the light-shielding plate during movement. The aforementioned buffer spring 308 works together with the damping block 309 to achieve buffering. This structure is a common existing buffer component and will not be described in detail here.

[0042] The sample testing section 2 is located on one side of the outside of the main body 1 of the tester. The sample testing section 2 includes a refractive prism seat 201 connected to the outer wall of the main body 1 of the tester by screws. A light-entering prism seat 202 is provided above the refractive prism seat 201. The light-entering prism seat 202 is rotatably connected to the inner wall of the main body 1 of the tester by bearings. By lifting control, the light-entering prism seat 202 can be moved upward, and the surface of the refractive prism seat 201 can be opened for placing the tempered glass sample in the solar cell module.

[0043] When the light-inlet prism holder 202 moves downward to reset, the sample can be pressed down and fixed. The side of the light-inlet prism holder 202 away from the main body 1 of the tester is connected to the light-transmitting prism 203 by screws. When the light-shielding part 4 moves upward to open the interior of the light-transmitting prism 203, the light-transmitting prism 203 is used to receive light and test the refractive index of the tempered glass sample in the solar cell module. The side of the refractive prism holder 201 away from the main body 1 of the tester is connected to the reflector 204 by screws.

[0044] Above the main body 1 of the tester, an eyepiece 5 is provided. The eyepiece 5 is rotatably connected to the top end of the main body 1 of the tester. When the eyepiece 5 is rotated and adjusted, it is convenient for the staff to observe and adjust the viewing angle of the sample. Below the main body 1 of the tester, a support base 6 is provided. The bottom end of the main body 1 of the tester is bolted to the top surface of the support base 6. The support base 6 provides a supporting function for the main body 1 of the tester. At the same time, an anti-slip pad is provided at the bottom end of the support base 6, which can increase the friction between the main body 1 of the tester and the surface of the workbench.

[0045] The reflecting mirror 204 is connected to the side of the refracting prism base 201 away from the main body 1 of the tester by screws. In this way, the space is utilized particularly, so that after the light passes through the refracting prism base 201 and the light-transmitting prism 203, it can be effectively reflected by the reflecting mirror 204, thereby completing the entire test process of the refractive index of light.

[0046] Embodiment 2

[0047] Please refer to Figure 1-7 , the support part 3 is arranged on the side of the sample testing part 2 away from the main body 1 of the tester, and the support part 3 is connected to the outer side wall of the sample testing part 2. The support part 3 includes a support frame body 301 connected to the outer side wall of the light incident prism base 202 by screws. The inside of the support frame body 301 is a hollow structure. The structural shape of the support frame body 301 is set as a "square" shape. The light shielding plate 401 is arranged inside the support frame body 301. Two groups of support rods 302 are connected to the top end of the support frame body 301 by screws. One end of the two groups of support rods 302 away from the support frame body 301 is connected to the outer side wall of the main body 1 of the tester by screws. The support rods 302 provide a supporting function for the support frame body 301, and the support frame body 301 is fixedly supported on the outer side wall of the sample testing part 2. When the light incident prism base 202 is lifted, the support frame body 301 can be lifted synchronously.

[0048] When the light incident prism base 202 is lifted, the support frame body 301 can be lifted synchronously. This synchronous movement mechanism ensures that the relative position relationship between the support part 3 and the sample testing part 2 remains consistent during the test process. In this way, it is possible to avoid interference problems between the light shielding plate 401 and the light-transmitting prism 203 or other components caused by changes in their relative positions.

[0049] The inside of the support frame body 301 is hollow and has a "square" structure. The light shielding plate 401 is arranged in this internal space. In this way, an accurate guiding and positioning space is provided for the light shielding plate 401. When the light shielding plate 401 moves up and down inside the support frame body 301, it can slide stably along the contour of the "square" shape without deviation or jamming. This design can improve the accuracy of the movement of the light shielding plate 401, thereby ensuring that the operation of blocking and opening the light shielding plate 401 for the light-transmitting prism 203 can be carried out accurately during the test.

[0050] The light-shielding part 4 is located inside the support part 3. The light-shielding part 4 includes a light-shielding plate 401 slidably disposed inside the support part 3. A connecting frame 402 is connected to the side of the light-shielding plate 401 away from the sample testing part 2 via screws. Mounting grooves 403 are formed on the two outer side walls of the connecting frame 402, and the connecting frame 402 has an "I"-shaped structure. Two sets of mounting grooves 403 are provided inside the connecting frame 402, symmetrically distributed along the vertical central axis of the connecting frame 402. Each set of mounting grooves 403 contains several sets of first-order telescopic rods 404. Telescopic rod 404 provides support and movement for connecting plate 406. Telescopic rod 404 is slidably connected to the inner wall of mounting groove 403. A cylindrical spring 405 is sleeved around the outer circumference of telescopic rod 404. One end of the cylindrical spring 405 is welded to the inner wall of mounting groove 403, and the other end is welded to the outer wall of connecting plate 406. The end of telescopic rod 404 away from connecting bracket 402 is welded to connecting plate 406. A push plate 407 is screwed to the side of connecting plate 406 away from light shield 401. The outer wall of push plate 407... A non-slip side plate 411 is connected by screws. Pushing the non-slip side plate 411 can move the push plate 407, increasing the friction between the hand and the push plate 407, making it easier to move the push plate 407. The side of the connecting plate 406 away from the first telescopic rod 404 is connected to a plug block 408 by screws. When the two sets of push plates 407 are squeezed together and moved closer, the extension and retraction functions of the cylindrical spring 405 and the first telescopic rod 404 can be used to move the connecting plate 406 laterally inside the mounting groove 403. At this time, the connecting plate 406 can drive the plug block 408 to move out of the fixed position. Inside the fixed slot 303, the limiting measures on the light-shielding plate 401 are released, making it easier to push the light-shielding plate 401 upward to open the interior of the light-transmitting prism 203 to receive light. After the position of the light-shielding plate 401 is adjusted upward, the squeezing force on the plug-in block 408 is released. At this time, the cylindrical spring 405 performs a stretching and reset operation. Using the reset force of the cylindrical spring 405, the connecting plate 406 is pushed towards the interior of the fixed slot 303. The connecting plate 406 pushes the plug-in block 408 into the interior of the fixed slot 303, thus achieving the purpose of fixing the light-shielding plate 401.

[0051] Example 3

[0052] Please see Figure 1-7Two sets of fixing slots 303 are provided on each of the two inner sidewalls of the support frame 301. The two sets of fixing slots 303 are symmetrically distributed on the transverse central axis of the support frame 301. The opening dimensions of the fixing slots 303 are the same as the end dimensions of the plug-in block 408. When the end of the plug-in block 408 away from the connecting plate 406 is inserted into the interior of the fixing slot 303 and is in close contact with the inner sidewall of the fixing slot 303, the light-shielding plate 401 after adjusting its height is fixed, reducing the problem of the light-shielding plate 401 sliding down and blocking the light. Sliding grooves 304 are provided on each of the two inner sidewalls of the support frame 301. The sliding groove 304 is located below the fixed slot 303. A sliding connecting block 409 is slidably disposed on the inner side of the sliding groove 304. The sliding connecting block 409 has a "T" shape. The part of the sliding connecting block 409 away from the sliding groove 304 extends to the outer side of the light shield 401 and is connected to the outer side wall of the light shield 401 by screws. When the light shield 401 moves up or down, the light shield 401 drives the sliding connecting block 409 to slide inside the sliding groove 304. This can provide support and sliding cooperation on both sides of the light shield 401, increasing the stability of the light shield 401 when it moves up and down.

[0053] The top and bottom surfaces of the light-shielding plate 401 are connected with connecting iron plates 410 by screws. The top and bottom surfaces of the support frame 301 are connected with magnetic plates 305 by screws. There are two sets of magnetic plates 305, which are respectively located above and below the light-shielding plate 401. When the light-shielding plate 401 is pushed upward, the magnetic plates 305 can magnetically attract the connecting iron plates 410, which helps the top of the light-shielding plate 401 to be tightly attached to the top surface of the support frame 301, thereby saving pushing force and fixing the top of the light-shielding plate 401.

[0054] Two sets of buffer grooves 306 are provided on the top and bottom surfaces inside the support frame 301. The positions of the buffer grooves 306 correspond to the vertical movement positions of the light shield 401. The two sets of buffer grooves 306 are symmetrically distributed on the vertical central axis of the support frame 301. A second telescopic rod 307 is slidably connected to the inner wall of each set of buffer grooves 306. The end of the second telescopic rod 307 away from the buffer groove 306 extends to the outside of the support frame 301. A damping block 309 is welded to the end of the second telescopic rod 307 away from the buffer groove 306. The second telescopic rod 307 and the buffer spring 308 can telescopically move inside the buffer groove 306. A buffer spring 308 is sleeved around the outer circumference of the second telescopic rod 307. 08. One end of the buffer spring 308 is welded to the inner wall of the buffer groove 306, and the other end of the buffer spring 308 is welded to the end of the damping block 309. When the magnet 305 attracts the connecting iron plate 410 and causes the light shield 401 to be in close contact with the support frame 301, the top of the light shield 401 contacts the damping block 309, pushing the damping block 309 to move toward the interior of the buffer groove 306. At this time, the damping block 309 applies a squeezing force to the buffer spring 308 and the second telescopic rod 307. The buffer spring 308 elastically buffers the force of the light shield 401, thereby reducing the vibration force generated by the collision between the light shield 401 and the support frame 301.

[0055] Two sets of magnets 305 are provided above and below the light shield 401. This arrangement ensures that the light shield 401 is subjected to uniform magnetic attraction in the vertical direction. Whether it is the fixation of the light shield 401 after it is moved into place, or the external interference that may be encountered during the test (such as slight collisions), it can be effectively resisted by this all-round magnetic attraction, which further enhances the stability of the fixation of the light shield 401.

[0056] During the raising and fixing of the light shield 401, magnetic adsorption ensures the stable position of the light shield, while the buffer structure plays a role when the light shield approaches the fixed position, avoiding collisions and vibrations caused by excessive pushing or external interference, making the movement and positioning of the light shield 401 smoother and more accurate throughout the test process.

[0057] When using it, first turn on the power switch of the main body 1 of the tester, hold the multiple sets of adjustment scale rings and rotate them in sequence to adjust the various parts of the main body 1 of the tester so that the main body 1 of the tester is aligned with the light source. Lift and move the light-inlet prism seat 202 upward to open the surface of the refraction prism seat 201. After cleaning the surface of the refraction prism seat 201, take out the tempered glass sample from the solar cell module and place it on the surface of the refraction prism seat 201. Move the light-inlet prism seat 202 downward to reset it and press down to fix the sample.

[0058] Next, push the two sets of push plates 407 closer to each other. At this time, the first telescopic rod 404 and the cylindrical spring 405 are compressed and shortened. The push plate 407 drives the connecting plate 406 to move laterally inside the mounting groove 403. Through the connecting plate 406, the plug block 408 is moved out of the fixed slot 303, releasing the limiting measures on the light shield 401. Push the light shield 401 upward to slide until the interior of the light-transmitting prism 203 is fully opened, so that the light-transmitting prism 203 can fully receive light.

[0059] Finally, the height of the light-shielding plate 401 is moved to align with the fixing slot 303 at the upper position. The magnet 305 magnetically attracts the connecting iron plate 410, causing the top of the light-shielding plate 401 to press tightly against the inner wall of the support frame 301, thus fixing the top of the light-shielding plate 401. Simultaneously, as the light-shielding plate 401 moves, it applies a pushing force to the damping block 309, causing it to move inward toward the buffer groove 306. At this time, the damping block 309 applies a squeezing force to the buffer spring 308 and the second telescopic rod 307, utilizing the buffer spring 308 to... The thrust is elastically buffered, and then the squeezing force on the push plate 407 is released. After the cylindrical spring 405 stops being stressed, it is stretched outward to reset, and a reset pushing force is applied to the connecting plate 406. The cylindrical spring 405 pushes the connecting plate 406 and the plug block 408 toward the fixed slot 303 until the end of the plug block 408 is inserted into the fixed slot 303, thus completing the fixing of the plug block 408. The operator holds the eyepiece 5 and rotates it to adjust it to a suitable observation angle. At this time, the test data of the sample is displayed on the digital display screen, and the work is finally completed.
