Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a flat-panel SOFC single-cell testing device. Background Technology

[0002] Solid oxide fuel cells (SOFCs), as a type of all-solid-state power generation device, have significant advantages such as wide fuel adaptability, high energy conversion efficiency, and zero pollution emissions. Among them, planar SOFCs have attracted much attention due to their compact structure and high power density. In order to further optimize the performance of planar SOFCs and promote their commercial application, it is particularly important to conduct accurate and reliable testing on individual cells. Therefore, a special testing device has been invented.

[0003] In existing technologies, most common testing devices employ a single-station design. In practical applications, this single-station testing device requires the placement and installation of batteries before testing, followed by disassembly and re-placement after testing. This significantly negatively impacts testing efficiency, especially when dealing with large-scale testing. When testing a large number of planar SOFC single cells of different specifications and performance, the single-station testing process necessitates a complete installation, testing, and disassembly process for each battery, making the entire testing cycle extremely lengthy and severely slowing down the battery testing progress.

The slider is slidably connected to the guide sleeve, the second connecting rod is slidably connected to the guide seat, and the guide rod is slidably connected to the guide sleeve. The pressure plate assembly is located at one end of the guide rod. When the placement seat rotates, the second connecting rod cooperates with the guide seat to drive the sliding rod to slide, and the sliding rod drives the slider and the rotating block to move.

[0008] In a preferred embodiment of this technical solution, the guide seat has a matching groove at the relative position of the second connecting rod, and the second connecting rod is slidably connected to the groove.

[0009] In the preferred embodiment of this technical solution, the guide sleeve has a matching groove at the relative position of the guide rod, and the guide rod is slidably connected to the groove.

[0010] In a preferred embodiment of this technical solution, the slider has a rotating groove that matches the rotating block, and the rotating block is rotatably connected to the rotating groove.

[0011] According to the preferred embodiment of this technical solution, the pressure plate assembly includes a third mounting base fixedly installed at the end of the guide rod away from the rotating block, a first threaded rod rotatably connected to the third mounting base, a third knob fixedly connected to one end of the first threaded rod, a second sliding seat threadedly connected to the first threaded rod, a limiting pressure plate installed on the second sliding seat, and a fastening bolt threadedly connected to the second sliding seat.

At the same time, the guide rod and the guide sleeve slide groove work together to rotate the limiting pressure plate to one side of the guide sleeve, so as to avoid the limiting pressure plate interfering with the picking up of the battery and further improve the convenience of the staff to pick up the battery.

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a flat-plate SOFC single-cell testing device, comprising a device body 1, a support leg 4 fixedly mounted on the device body 1, a testing component mounted on the device body 1, a first motor 21 fixedly mounted on the device body 1, a first connecting rod 22 fixedly connected to the output end of the first motor 21, a first fixing rod 23 fixedly connected to the first connecting rod 22, a rotating disk 24 rotatably connected to the device body 1, a placement seat 25 fixedly connected to the rotating disk 24, a limiting component mounted on the placement seat 25, a guide component mounted on the device body 1 and the placement seat 25, and a pressure plate component mounted on the guide component. The first fixing rod 23 is slidably connected to the rotating disk 24. The first motor 21 drives the first connecting rod 22 to rotate. The limiting component is used to initially limit the battery position. The guide component is used to adjust the movement of the pressure plate component. Before installation, the required pressure plate component is installed on the guide component according to the actual usage, and the limiting component is adjusted accordingly. The device initially limits the battery to prevent it from moving left or right. Subsequently, as the first motor 21 operates, it adjusts the rotation of the rotating disk 24 and its connected components. The guide component then moves the pressure plate assembly towards the battery, effectively restricting it. During testing, the first motor 21 drives the first connecting rod 22 to rotate, which in turn drives the first fixed rod 23, which is fixedly connected to it, to rotate synchronously. The first fixed rod 23 slides on the rotating disk 24, causing the rotating disk 24 to rotate. This, in turn, rotates the placement seat 25, which is fixedly connected to the rotating disk 24, to a preset position. Testing is then conducted using the testing components. After testing, the first motor 21 adjusts the placement seat 25, moving the battery and components to allow subsequent batteries to enter the testing area for further testing. When the tested battery moves to the disassembly area, the guide component lifts the pressure plate assembly, releasing the restriction on the battery. The operator can then disassemble and reinstall the battery, completing the testing process.

[0019] A further embodiment of this solution is as follows: the limiting component includes a first mounting base 26 fixedly mounted on the placement base 25, a first bidirectional threaded rod 27 rotatably connected to the first mounting base 26, a first knob 28 fixedly connected to one end of the first bidirectional threaded rod 27, a first sliding seat 29 threadedly connected to the first bidirectional threaded rod 27, a second bidirectional threaded rod 210 rotatably connected to the first sliding seat 29, a second knob 211 fixedly connected to one end of the second bidirectional threaded rod 210, and a limiting plate 212 threadedly connected to the second bidirectional threaded rod 210. The first knob 28 is used to adjust the rotation of the first bidirectional threaded rod 27, and the second knob 211 is used to adjust the rotation of the second bidirectional threaded rod 210. The rotation of the knob 28 drives the first bidirectional threaded rod 27 to rotate, which in turn drives the two first sliding seats 29 to move closer or further away synchronously along the axial direction of the first bidirectional threaded rod 27, thus achieving preliminary limiting adjustment of the workpiece to be processed on the placement seat 25 in the first direction. Then, the second knob 211 drives the second bidirectional threaded rod 210 to rotate, which in turn drives the two limiting plates 212 to move closer or further away synchronously along the axial direction of the second bidirectional threaded rod 210, thus achieving precise limiting adjustment of the workpiece to be processed in the second direction perpendicular to the first direction. Finally, through the coordinated limiting in both directions, the workpiece to be processed is stably fixed on the placement seat 25, preventing displacement during subsequent operations and improving the overall stability and reliability of the device.

[0020] A further embodiment of this solution is as follows: the guide assembly includes a second mounting base 213 fixedly mounted on the placement base 25, a guide sleeve 214 fixedly mounted on the second mounting base 213, a sliding rod slidably connected to the second mounting base 213 and the placement base 25, a second connecting rod fixedly connected to one end of the sliding rod, a guide seat 226 fixedly mounted on the device body 1, a slider fixedly mounted on the end of the sliding rod away from the second connecting rod, a rotating block rotatably connected to the slider, and a guide rod fixedly mounted on the rotating block. The slider is slidably connected to the guide sleeve 214, and the second connecting rod is slidably connected to the guide seat 226. The pressure plate assembly is attached to the guide sleeve 214 and is located at one end of the guide rod. When the placement seat 25 rotates, it cooperates with the guide seat 226 through the second connecting rod, which drives the sliding rod to slide. The sliding rod drives the slider and the rotating block to move. When the placement seat 25 rotates, it drives the connected second connecting rod to its specific position. Under the constraint of the guide seat 226, the second connecting rod slides along a specific trajectory, which in turn drives the sliding rod to slide along the preset path between the second mounting seat 213 and the placement seat 25. During the sliding of the sliding rod, it simultaneously drives the slider and its connected components to slide stably within the guide sleeve 214, causing the pressure plate assembly to rise and release the restriction on the battery.

[0021] A further solution based on this embodiment is as follows: the guide seat 226 has a matching groove at the relative position of the second connecting rod. The second connecting rod is slidably connected to the groove. The groove can provide a clear and stable sliding trajectory for the second connecting rod, preventing the second connecting rod from deviating during the sliding process. At the same time, through the cooperation between the guide seat 226 and the second connecting rod, the connected component is driven to rise, so that the pressure plate assembly releases the restriction on the battery, so that the staff can install and place the battery.

[0022] A further solution based on this embodiment is as follows: the guide sleeve 214 has a matching groove at the relative position of the guide rod, the guide rod is slidably connected to the groove, and the matching groove on the guide sleeve 214 can strictly constrain the sliding direction of the guide rod to prevent the guide rod from wobbling radially or deviating from the preset path when sliding, ensuring that the guide rod slides stably. At the same time, when components such as the slider are raised, the guide rod cooperates with its groove to drive the pressure plate assembly to rotate to one side of the guide sleeve 214, so as to avoid the pressure plate assembly affecting or interfering with the battery when the staff takes it out.

[0023] A further solution based on this embodiment is as follows: a rotating groove adapted to the rotating block is provided on the slider, the rotating block is rotatably connected to the rotating groove, the rotating groove can provide stable rotational support for the rotating block, ensuring that the rotating block can rotate flexibly around the axis of the rotating groove, and there will be no deviation during the rotation; the adaptation structure between the rotating groove and the rotating block can limit the axial displacement of the rotating block, prevent the rotating block from falling off when rotating or moving with the slider, and ensure the stability of the transmission of the guide assembly.

[0024] A further embodiment of this solution is as follows: the pressure plate assembly includes a third mounting base fixedly installed at the end of the guide rod away from the rotating block, a first threaded rod rotatably connected to the third mounting base, a third knob fixedly connected to one end of the first threaded rod, a second sliding seat threadedly connected to the first threaded rod, a limiting pressure plate 224 installed on the second sliding seat, and a fastening bolt threadedly connected to the second sliding seat. The third knob is used to adjust the rotation of the first threaded rod. By driving the first threaded rod to rotate through the third knob, the second sliding seat can be moved axially along the first threaded rod, thereby adjusting the distance between the limiting pressure plate 224 and the battery, so as to achieve pressing adaptation for batteries of different thicknesses or sizes. Moreover, the limiting pressure plate 224 adopts a detachable design. During use, different limiting pressure plates 224 can be disassembled and replaced to adapt to the required batteries, thereby improving the flexibility and reliability of operation.

[0025] A further embodiment of this solution is as follows: The test component includes a first fixed bracket 31 fixedly mounted on the main body 1 of the device, a second motor 32 fixedly mounted on the first fixed bracket 31, a second threaded rod 33 fixedly connected to the output end of the second motor 32, a sliding bracket 34 threadedly connected to the second threaded rod 33, a third motor fixedly mounted on the sliding bracket 34, a third threaded rod fixedly connected to the output end of the third motor, an electrical performance test module body threadedly connected to the third threaded rod, and the sliding bracket 34 slidably connected to the first fixed bracket 31. The electrical performance test module body is slidably connected to the sliding bracket 34. The second motor 32 is used to drive the rotation of the second threaded rod 33, and the sliding bracket 34 is moved by adjusting the rotation of the second threaded rod 33. The third motor drives the third threaded rod to rotate, which in turn moves the electrical performance testing module body. When the second motor 32 drives the second threaded rod 33 to rotate, the sliding bracket 34 moves axially along the second threaded rod 33 under the constraint of the first fixed bracket 31, thus adjusting the position of the electrical performance testing module body in the first direction. When the third motor drives the third threaded rod to rotate, the electrical performance testing module body moves axially along the third threaded rod under the constraint of the sliding bracket 34, thus adjusting its position in the second direction, which is perpendicular to the first direction. Through coordinated adjustment in both directions, the electrical performance testing module body can be precisely moved to the test position, adapting to the electrical performance testing needs of components with different specifications and test points, thereby improving testing efficiency and accuracy.

[0026] Working principle: Before installation, select the required limiting pressure plate 224 according to the actual usage. After installing it on the second sliding seat, use the fastening bolts to restrict the limiting pressure plate 224 to complete the installation. According to the battery height, turn the third knob to drive the first threaded rod to rotate. When the first threaded rod rotates, it drives the second sliding seat to slide on the third mounting seat, thereby adjusting the limiting pressure plate 224 to a suitable height. According to the battery size, turn the first knob 28 to drive the first bidirectional threaded rod 27 to rotate. The rotation of the first bidirectional threaded rod 27 drives the first sliding seats 29 on both sides to slide synchronously and mirror-slide, adjusting the vertical position of the limiting plate 212. Then, turn the second knob 211 to drive the second bidirectional threaded rod 210 to rotate. The rotation of the second bidirectional threaded rod 210 drives the limiting plate 212 to move, adjusting the distance between the limiting plates 212. After adjustment, place the battery between the limiting plates 212 and prepare to carry out the test. During testing, the first motor 21 operates, driving the first connecting rod 22 to rotate. The first connecting rod 22 drives the first fixed rod 23, which is fixedly connected to it, to rotate synchronously. The first fixed rod 23 slides on the rotating disk 24, thereby driving the rotating disk 24 to rotate, which in turn causes the placement seat 25, which is fixedly connected to the rotating disk 24, to rotate to a preset position. The test is carried out by the operation of the test components. During testing, the second motor 32 is first started, driving the second threaded rod 33 to rotate. Since the sliding bracket 34 is threaded onto the second threaded rod 33 and slidably connected to the first fixed bracket 31, the rotation of the second threaded rod 33 causes the sliding bracket 34 to move, which in turn causes the electrical performance test module body on the sliding bracket 34 to move synchronously, achieving position adjustment of the test module in the first direction. Then, the third motor works, driving the third threaded rod connected to the output end to rotate, causing the electrical performance test module body to move, achieving fine adjustment of the test module's position in the second direction. Through the coordinated drive of the second motor 32 and the third motor, the electrical performance test module body is precisely moved to a position aligned with the battery test point. Subsequently, the electrical performance test module body is started to test the electrical performance parameters of the SOFC single cell. During the test, the test components monitor the real-time operating status of the test device and the battery test data to ensure the stability of the test process and the accuracy of the data. After the test is completed, the first motor 21 works to adjust the rotation of the rotating disk 24 and its connected components, causing the battery to move, allowing subsequent batteries to enter the test area for further testing. When the placement seat 25 moves the tested battery to the disassembly area, the guide seat 226, in conjunction with the second connecting rod, causes the sliding rod to rise. As the sliding rod rises, the connected slider and rotating block rise synchronously. When the rotating block rises, the guide rod, in conjunction with the guide groove of the guide sleeve 214, causes the third mounting seat and the installed limiting plate 224 to rotate to one side of the guide sleeve 214. This prevents the limiting plate 224 from interfering with the operator's handling of the battery. After the operator removes the tested battery and installs a new battery on the limiting plate 212, the placement seat 25 rotates again to move the battery. Simultaneously, the guide seat 226, in conjunction with the second connecting rod, causes the limiting plate 224 to move closer to the battery, restoring sufficient restriction on the battery. This process is repeated to perform the testing.
