Description

Technical Field

[0001] This application relates to the field of battery testing technology, specifically a perovskite battery testing platform. Background Technology

[0002] Perovskite solar cells are a novel type of solar cell that primarily uses perovskite-structured materials as the light-absorbing layer. Perovskite materials exhibit excellent performance in terms of photoelectric conversion efficiency and manufacturing cost, thus attracting widespread research and attention.

[0003] To ensure the performance of perovskite solar cells, testing equipment is typically used to test them. Common testing methods include electrical performance testing, stability testing, and charge / discharge testing. Among these, charge / discharge testing is a crucial step in evaluating their performance and stability.

[0004] Charge-discharge tests are typically used to evaluate the energy density and efficiency of batteries. When conducting charge-discharge tests on perovskite batteries, discharge heads are usually placed on both sides of the battery. The two discharge heads form an open-circuit voltage, and the two discharge heads are subjected to multiple charge-discharge cycles to obtain the battery's current, voltage, and capacity data.

[0005] Existing testing devices fix the battery in place by directly contacting both ends of the battery with the discharge head during testing. However, the battery tends to sway as it moves with the transport mechanism. The contact between the discharge head and the battery alone is insufficient to keep the battery stable during testing, leading to poor contact at the electrode-battery connection points. This results in inaccurate measurement results and poses safety hazards. Therefore, it is necessary to provide a perovskite battery testing platform to solve these problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a perovskite solar cell testing platform that eliminates the need for manual loading, unloading, and sorting of the cells to be tested, thereby reducing testing time and saving manpower.

[0008] The technical solution adopted by this application to solve its technical problem is: a perovskite solar cell testing platform, including:

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0036] like Figure 1 As shown, this application provides a perovskite solar cell testing platform, including a platform base 1, the upper end of which is provided with a conveying mechanism 2 for transporting perovskite solar cells;

[0037] The conveying mechanism 2 has two sets of transmission sprockets 21, which are rotatably connected to the upper sides of the platform base 1. In this application, a reduction motor (not shown) is provided on one side of one set of transmission sprockets 21 to drive the transmission sprockets 21 to rotate. A transmission chain 22 is connected to the outer side of the transmission sprockets 21. Multiple sets of placement shells 23 are uniformly fixedly installed on the outer side of the transmission chain 22. The placement shells 23 are used to place the batteries to be tested. Therefore, starting the reduction motor causes the transmission sprockets 21 to rotate, which drives the transmission chain 22 to move. At the same time, the placement shells 23 are driven, thus moving the batteries to be tested.

[0038] Meanwhile, a feeding mechanism 4 is provided on the upper side of the conveying mechanism 2. The feeding mechanism 4 is used to transfer the battery to be tested to the conveying mechanism 2. The feeding mechanism 4 has a placement platform 41 fixedly installed on one side of the platform seat 1. A feeding box 42 is fixedly installed on the upper end of the placement platform 41. A discharge port is provided on the side of the feeding box 42 near the platform seat 1. An inclined plate 43 is fixedly installed at the discharge port. In this application, a switch baffle plate (not shown in the figure) is provided at the discharge port. The number of batteries in the feeding box 42 entering the inclined plate 43 can be controlled by the switch baffle plate.

[0039] The other end of the inclined plate 43 is located above the conveying mechanism 2. A stop 44 is fixedly installed on the side of the inclined plate 43 near the conveying mechanism 2. The stop 44 has an opening that is located above the placement shell 23. Therefore, the battery slides down through the inclined plate 43 and enters the stop 44, and falls down along the opening onto the placement shell 23, thus completing the feeding of the detection mechanism 3.

[0040] like Figures 2-3 As shown, detection mechanisms 3 are provided on both sides of the conveying mechanism 2. The detection mechanism 3 is used to detect the batteries transported on the conveying mechanism 2. The detection mechanism 3 has a control board 31 provided on both sides of the placement shell 23. Multiple sets of electrically connected discharge heads 32 are fixedly installed in the control board 31. It should be noted that there are two sets of detection mechanisms 3 located on both sides of the placement shell 23. The discharge heads 32 of the two sets of detection mechanisms 3 form an open circuit voltage, which facilitates the detection of the batteries on the placement shell 23.

[0041] To better adjust the position of the control board 31, a drive component 35 is provided on the side of the control board 31 away from the housing 23. The drive component 35 has a slide rail 351 fixedly installed on the upper end of the platform base 1. A slider 352 is slidably connected to the upper end of the slide rail 351. A mounting base 354 is fixedly installed on the upper end of the slider 352. A connecting rod 355 is fixedly installed between the mounting base 354 and the control board 31. At the same time, a first cylinder 353 is fixedly installed on the upper end of the platform base 1. The output shaft of the first cylinder 353 is fixed to the end of the slider 352 away from the control board 31. Therefore, starting the first cylinder 353 can push the mounting base 354 and the slider 352 to slide on the slide rail 351, thereby driving the control board 31 and the discharge head 32 to move as a whole, so that they are attached to the end of the battery to be tested.

[0042] To improve the stability of the battery during the testing process, a pressing member 11 is provided above the testing mechanism 3. The pressing member 11 can press the battery to be tested to prevent shaking during the testing process. The pressing member 11 has support columns 111 fixed to both sides of the conveying mechanism 2, and a top plate 112 is fixedly installed at the upper end of the support column 111. A sliding rod 113 is slidably connected at the center of the top plate 112, and a pressure plate 114 is fixedly installed at the bottom end of the sliding rod 113. The pressure plate 114 is located above the placement shell 23. In this application, both sides of the bottom end face of the pressure plate 114 are set with arc corners, which facilitates the battery to enter under the pressure plate 114.

[0043] Meanwhile, a spring 115 is fixedly installed between the pressure plate 114 and the top plate 112. The spring 115 is sleeved on the outside of the slide rod 113. Therefore, when the conveying mechanism 2 drives the battery to move to the detection mechanism 3, the battery enters under the pressure plate 114 through the arc angle. During this process, the pressure plate 114 will be squeezed upward. At this time, the spring 115 contracts and rebounds, pressing the pressure plate 114 towards the battery, thus pressing the battery to prevent it from shaking during detection.

[0044] like Figure 1 and Figure 4 As shown, a collection mechanism 5 is provided on the side of the detection mechanism 3 away from the feeding mechanism 4. The collection mechanism 5 has a transmission channel 51 fixedly installed on the upper end of the platform base 1. The transmission channel 51 is located on one side of the placement shell 23. A collection box 52 is fixedly installed at the other end of the transmission channel 51. The collection box 52 is used to collect the batteries in the transmission channel 51.

[0045] In order to collect the tested batteries into the conduction channel 51, a fixed seat 53 is fixedly installed on the upper end of the platform base 1. The fixed seat 53 is located on the other side of the placement shell 23. A second cylinder 54 is fixedly installed on the upper end of the fixed seat 53. In this application, the number of the second cylinders 54 is the same as the number of conduction channels 51, and the output shaft of the second cylinder 54 faces the conduction channel 51. A push rod 55 is fixedly installed on the output shaft of the second cylinder 54.

[0046] In this application, the detection mechanism 3, the conveying mechanism 2, and the collection mechanism 5 are controlled by a PLC.

[0047] In summary: When testing perovskite solar cells, the conveying mechanism 2 is started, and then the feeding mechanism 4 is opened to allow the cells to be tested to enter the placement shell 23. The cells then move with the placement shell 23 and enter under the pressure plate 114. The pressure plate 114 presses down on the cells to prevent them from shaking during testing.

[0048] Then, when the battery reaches the detection mechanism 3, the conveying mechanism 2 is stopped, and the discharge head 32 is driven towards the battery by the drive unit 35 until it is attached to both ends of the battery to form an open circuit voltage and the battery is tested.

[0049] After the test is completed, the conveying mechanism 2 continues to transport the battery until it reaches the collection mechanism 5. At this point, the conveying mechanism 2 stops, and then the second cylinder 54 extends, driving the push rod 55 to extend and push the tested battery toward the conduction channel 51. Then the second cylinder 54 is retracted, and the conveying mechanism 2 continues to drive. The above operation is repeated to ensure that the battery remains stable during the test, avoid poor contact between the electrode and the battery due to shaking, ensure the accuracy of the measurement structure, and prevent safety hazards.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
