Description

Technical Field

[0001] This utility model belongs to the field of battery cell testing technology, specifically relating to a reflectivity tester. Background Technology

[0002] In the manufacturing process of solar cells, testing the light reflection intensity of textured sheets across different wavelengths involves multiple aspects, including the optical properties of the materials, measurement methods, and techniques. The reflection intensity of textured sheets is affected by the inherent characteristics of the materials themselves, such as transmittance, reflectance, and absorptivity. These parameters are not only important indicators for evaluating the performance of optical materials but also key bases for developing novel optoelectronic materials.

[0003] Typically, a reflectivity tester is used to measure the reflectivity of the textured film for different wavelengths of light, performing multi-point automatic measurements. The test results are then presented as a visual curve to help customers monitor the reflectivity and film thickness of the solar cells. Existing testers include a tray that extends from the test area. The solar cells are placed on the tray, which then retracts to test them. After testing, the tray extends again to remove the tested solar cells. The tray is equipped with limiting areas and posts that match the solar cells to restrict their movement.

[0004] Reflectivity testers are typically located in a dedicated testing room. The solar cells to be tested on the production line are usually transported to the testing room in containers for testing. During testing, the solar cells need to be taken out of the container and placed on the tester. After the test, the solar cells need to be put back into the container. When the container is far from the tester, the solar cells need to be taken out and put back in, which increases the time spent taking out and putting back the solar cells and affects the efficiency of the test.

[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figures 1 to 5 As shown, a reflectivity tester according to one embodiment of the present invention includes a tester body 11, a tray 12 on the tester body 11, a limiting area 15 on the tray 12 that matches the battery cell 22 to be tested, the limiting area 15 facilitates quick positioning of the battery cell 22 to be tested, and a limiting post 13 located outside the limiting area 15 on the tray 12. When the battery cell 22 to be tested is placed on the tray 12, the limiting post 13 and the limiting area 15 can limit the battery cell 22 to be tested, so that the battery cell 22 to be tested is in an accurate testing position.

[0028] A first support plate 14 is fixedly connected to the main body 11 of the tester, and a second support plate 31 is fixedly connected to the first support plate 14. A housing 21 is provided on the second support plate 31. The housing 21 is located between the second support plate 31 and the tray 12. Multiple first receiving slots 23 that match the limiting area 15 are opened inside the housing 21. The opening of the first receiving slot 23 faces the tray 12. A battery cell 22 is provided inside the first receiving slot 23. The battery cell 22 is parallel to the upper surface of the tray 12.

[0029] The second support plate 31 has a movable groove 32, a movable block 34 is slidably connected in the movable groove 32, a movable plate 35 is fixedly connected to the movable block 34, and a screw 33 threadedly connected to the movable block 34 is rotatably connected to the second support plate 31.

[0030] Specifically, the housing 21 is placed on the movable plate 35, which supports the housing 21. By rotating the lead screw 33, the movable block 34 and the movable plate 35 can be moved up and down, thereby moving the housing 21 up and down, and causing the multiple battery cells 22 inside the housing 21 to move up and down.

[0031] The bottom surface of the topmost battery cell 22 is aligned with the top surface of the tray 12. The end of the battery cell 22 that protrudes from the housing 21 is the pull-out end, which can be easily moved by hand from the first receiving groove 23 to the tray 12. During the removal process, the bottom surface of the battery cell 22 contacts the top surface of the tray 12 until the battery cell 22 moves into the limiting area 15.

[0032] After the battery cell 22 is tested, push the battery cell 22 away from the end face of the housing 21 so that the battery cell 22 moves toward the empty first receiving slot 23. Under the limiting action of the limiting post 13, the battery cell 22 can be guaranteed not to shift its position during the movement until the battery cell 22 is returned to the first receiving slot 23.

[0033] A limiting plate 36 is fixedly connected to the movable plate 35, and a set of limiting frames 37 are fixedly connected to the movable plate 35. The limiting plate 36 and the limiting frames 37 can limit the position of the housing 21, thereby limiting the position of the battery cell 22, so that the position of the battery cell 22 is aligned with the limiting area 15, and the battery cell 22 can move accurately into the limiting area 15. When the battery cell 22 moves to the tray 12, no secondary adjustment is required.

[0034] The second support plate 31 is provided with a scale line 38. When the upper end face of the box 21 is aligned with the scale line 38, the bottom end face of the battery cell 22 is aligned with the upper end face of the tray 12. After testing a battery cell 22, the screw 33 is rotated to move the box 21 upward, and the upper end face of the box 21 is aligned with the scale line 38 above, so that the bottom end face of the next battery cell 22 to be tested is aligned with the upper end face of the tray 12.

[0035] A handle 25 is fixedly connected to the housing 21, a receiving box 26 is fixedly connected to the housing 21, and a cover 41 is provided on the housing 21. Multiple second receiving slots 42 that match the battery cells 22 are opened inside the cover 41.

[0036] Specifically, the cover 41 can be placed on the housing 21 to protect the battery cells 22 when they are moved from the production line to the testing room. When the cells arrive at the testing room, the cover 41 is opened, the housing 21 is placed on the moving plate 35, and the battery cells are removed from the housing 21 for testing. After testing, the cover 41 is placed back on the housing 21, and the tested battery cells 22 are taken back to the workshop. The handle 25 facilitates the movement of the housing 21. The test reports can be placed in the container 26 and taken back together for easy access to the data of the tested battery cells 22.

[0037] The housing 21 has a fixing groove 24 inside, and a fixing plate 43 that matches the fixing groove 24 is fixedly connected to the cover 41. The length of the fixing plate 43 is greater than the length of the battery cell 22 protruding from the housing 21. The fixing plate 43 can be snapped into the fixing groove 24. When the fixing plate 43 is inserted into the fixing groove 24, the protruding battery cell 22 has not yet come into contact with the cover 41, thus supporting the cover 41 and preventing the cover 41 from crushing the battery cell 22.

[0038] When using, refer to Figures 1-5 As shown, the housing 21 storing the battery cell 22 to be tested is placed on the moving plate 35. The position of the battery cell 22 is adjusted by rotating the screw 33. The battery cell 22 can be accurately placed in the limiting area 15 on the limiting post 13 during the process of moving out of the housing 21.

[0039] After placing the battery cell 22 on the tray 12, the battery cell 22 is tested. After the test is completed, the battery cell 22 can be retracted into the box 21 during the process of removing the battery cell 22 from the tray 12, which greatly saves the time of picking up and putting down the battery cell 22 and increases the testing efficiency.

[0040] Compared with the prior art, the reflectivity tester of this utility model can quickly place the battery cell to be tested on the tray, and after the test is completed, it can quickly remove the tested battery cell from the tray and put it back into the container, reducing the time for picking up and putting down the battery cell and increasing the testing efficiency.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
