Description

Technical Field

[0001] This utility model relates to the technical field of solid-state battery testing devices; more specifically, it relates to a solid-state battery electrode surface treatment and defect detection device. Background Technology

[0002] Solid-state batteries are a type of battery technology. Unlike the commonly used lithium-ion and lithium-ion polymer batteries, solid-state batteries use solid electrodes and solid electrolytes. When solid-state battery electrodes are manufactured or during after-sales maintenance, multiple tests are required on the surface treatment and defects of the solid-state battery electrodes to ensure safe use.

[0003] Currently, existing solid-state battery testing devices typically use high-magnification microscopes to observe the surface smoothness, uniformity, and microstructure of solid-state battery electrodes. During testing, the optical microscope is usually positioned in a specific location, making it inconvenient to adjust the position according to different testing conditions, thus reducing the practicality of the equipment. Furthermore, existing solid-state battery testing devices generally require a mobile trolley to move the solid-state battery electrodes to the testing equipment before use. During testing, the trolley may shift, affecting the testing results. Additionally, when moving the solid-state battery electrodes to the testing equipment, auxiliary ramps are usually needed to move them to the appropriate position. However, since solid-state battery electrodes are generally heavy, manual pushing is time-consuming and laborious, further reducing the convenience of the equipment. Therefore, there is an urgent need for a solid-state battery electrode surface treatment and defect detection device to solve these problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a solid-state battery electrode surface treatment and defect detection device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a solid-state battery electrode surface treatment and defect detection device, including a base plate, with mounting frames fixedly connected to both sides of the top surface of the base plate, and two sets of mounting frames are provided. The mounting frames are provided with a moving structure inside, and a displacement structure is provided between the two sets of mounting frames. An optical microscope body is fixedly connected to the bottom end of the displacement structure. A temperature detector is fixedly connected to the bottom end of the two sets of mounting frames that are close to each other. A positioning structure is provided inside the mounting frame.

[0006] The moving structure includes a first motor, a second lead screw, and a guide rod, with the first motor installed at the upper end of one side of the outer surface of the mounting bracket.

[0007] The displacement structure includes a movable plate, the outer surface of the second lead screw is fitted with the movable plate, and the guide rod is movably connected to the movable plate;

[0008] The positioning structure includes a movable groove, and there are two sets of movable grooves, with the two sets of movable grooves respectively opened at both ends of one side of the bottom plate.

[0009] Preferably, the moving structure further includes a first lead screw, the output end of the first motor is connected to the first lead screw via a bearing, and one end of the first lead screw is connected to the interior of one side of the mounting bracket via a rotating shaft. A moving block is threaded onto the outer surface of the first lead screw, and a sliding rod is fixedly connected to the interior of the other side of the mounting bracket. A slider is sleeved on the outer surface of the sliding rod. A second lead screw is connected to the side of the slider and the moving block that are close to each other, and a guide rod is fixedly connected to the bottom end of the side of the moving block and the slider that are close to each other. This design can control the overall displacement structure to move back and forth horizontally and longitudinally between the two sets of mounting brackets.

[0010] Preferably, the external dimensions of the movable block are adapted to the internal dimensions of the mounting bracket on one side, and the external dimensions of the slider are adapted to the internal dimensions of the mounting bracket on the other side. This design makes the displacement structure more stable when moving.

[0011] Preferably, the displacement structure further includes a drive motor, which is mounted on the top surface of the moving plate. The output shaft of the drive motor is connected to a first bevel gear. Inside the moving plate, a second bevel gear meshes with the first bevel gear via a shaft, and the second bevel gear is threadedly connected to a second lead screw. This design allows the moving plate to move back and forth on the outer surface of the second lead screw.

[0012] Preferably, the positioning structure further includes a second motor, which is mounted on one end of the outer surface of the base plate. The output end of the second motor is connected to a rotating rod via a bearing. One end of the rotating rod is connected to the bottom of the movable groove on one side via a rotating shaft. A worm gear is fixedly connected to the outer surface of the rotating rod inside the movable groove on one side. A turbine gear meshing with the worm gear is provided inside the movable groove on one side. Guide grooves are provided on both sides of the groove, and guide blocks are inserted inside the guide grooves. A support rod is fixedly connected to the side of the two sets of guide blocks that are close to each other. The support rod is connected to the turbine gear via a rotating shaft. Support blocks are connected to the outer surfaces of both ends of the support rod via bearings. A first movable frame is fixedly connected to the top of the support block. A second movable frame is provided inside the movable groove on the other side. This design allows the first movable frame to move back and forth inside the movable groove.

[0013] Preferably, the internal dimensions of the guide groove are adapted to the external dimensions of the guide block, and the external dimensions of the first and second moving frames are adapted to the internal dimensions of the two sets of movable grooves, respectively. This design makes the turbine move more stably.

[0014] The technical effects and advantages of this utility model are as follows: By starting the first motor, the first lead screw is driven to rotate, causing the moving block to move on the outer surface of the first lead screw. Under the action of the second lead screw, the slider moves synchronously on the outer surface of the slide bar. At the same time, the drive motor is started, which drives the first bevel gear to rotate. Because the first bevel gear and the second bevel gear mesh, the second bevel gear is driven to rotate, causing the moving plate to move on the outer surface of the second lead screw. This design allows for adjustment of the horizontal or vertical position of the optical microscope body, enabling the optical microscope body to be adjusted to a suitable position according to different detection conditions. It also allows for careful inspection of the surface finish, uniformity, and microstructure of solid-state battery electrodes, thereby improving the practicality of the equipment to a certain extent.

[0015] By pushing the mobile trolley onto the surface of the base plate, the wheels at both ends of the bottom side of the trolley will respectively engage with the first and second moving frames. Then, starting the second motor drives the rotating rod to rotate, causing the worm gear to rotate as well. Because the worm gear meshes with the worm, the first moving frame and the support block move within the movable slot, simultaneously moving the second moving frame. The second motor stops when the first and second moving frames reach the bottom position on one side of the movable slot. This design prevents the mobile trolley from shifting during the testing of solid-state battery electrodes, thus maintaining stable testing results. Furthermore, the first and second moving frames make moving the solid-state battery electrodes into the testing equipment easier and less labor-intensive, and the operation is simple, improving the equipment's convenience. Moreover, its overall structure is simple and reasonable, highly practical, and easy to promote and apply. Attached Figure Description

[0023] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation.

For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model should fall within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1-3 As shown, this embodiment proposes a solid-state battery electrode surface treatment and defect detection device, including a base plate 1. Mounting brackets 2 are fixedly connected to both sides of the top surface of the base plate 1, and there are two sets of mounting brackets 2. A moving structure 3 is provided inside the mounting brackets 2. A displacement structure 4 is provided between the two sets of mounting brackets 2. An optical microscope body 5 is fixedly connected to the bottom end of the displacement structure 4. A temperature detector 6 is fixedly connected to the bottom end of the two sets of mounting brackets 2 on the side that are close to each other. A positioning structure 7 is provided inside the mounting brackets 2.

[0026] The moving structure 3 includes a first motor 31, a second lead screw 36, and a guide rod. The first motor 31 is mounted on the upper end of one side of the outer surface of the mounting bracket 2. The moving structure 3 also includes a first lead screw 32. The output end of the first motor 31 is connected to the first lead screw 32 via a bearing, and one end of the first lead screw 32 is connected to the inside of the mounting bracket 2 via a rotating shaft. A moving block 33 is threadedly connected to the outer surface of the first lead screw 32. A sliding rod 34 is fixedly connected inside the mounting bracket 2 on the other side, and a slider 35 is sleeved on the outer surface of the sliding rod 34. The slider 35 and the moving block 36 are connected to the sliding rod 36. The second lead screw 36 is connected to the bearing on the side of the blocks 33 that are close to each other, and the guide rod is fixedly connected to the bottom end of the side of the moving block 33 and the slider 35 that are close to each other. This design can drive the moving block 33 to move back and forth on the outer surface of the first lead screw 32 by rotating the first lead screw 32. Under the connection and support of the second lead screw 36, the slider 35 can move synchronously on the outer surface of the slider 34, thereby controlling the moving distance of the displacement structure 4. Under the action of the guide rod, the position of the optical microscope body 5 can always be at the bottom end of the displacement structure 4.

[0027] The external dimensions of the movable block 33 are adapted to the internal dimensions of the mounting bracket 2 on one side, and the external dimensions of the slider 35 are adapted to the internal dimensions of the mounting bracket 2 on the other side. This design makes the movable block 33 and slider 35 more stable when moving, and makes the displacement structure 4 more stable when moving.

[0028] The shifting structure 4 includes a moving plate 41, on the outer surface of the second lead screw 36, and a guide rod is movably connected to the moving plate 41. The shifting structure 4 also includes a drive motor 42, which is mounted on the top surface of the moving plate 41. The output shaft of the drive motor 42 is connected to a first bevel gear 43. Inside the moving plate 41, a second bevel gear 44 is provided through a shaft to mesh with the first bevel gear 43. The second bevel gear 44 is threadedly connected to the second lead screw 36. This design allows the rotation of the first bevel gear 43 to drive the second bevel gear 44 to rotate, so that the second bevel gear 44 can move back and forth on the outer surface of the second lead screw 36, and drive the moving plate 41 as a whole to move on the surface of the second lead screw 36, thereby controlling the horizontal position of the optical microscope body 5 between the two sets of mounting brackets 2.

[0029] Example 2

[0030] like Figure 4 and Figure 5 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0031] The positioning structure 7 includes two sets of movable grooves 71, each set located at one end of an inner side of the base plate 1. The positioning structure 7 also includes a second motor 72, mounted on one end of the outer surface of the base plate 1. A rotating rod 73 is connected to the output end of the second motor 72 via a bearing. One end of the rotating rod 73 is connected to the bottom of the movable groove 71 on one side via a shaft. A worm gear 74 is fixedly connected to the outer surface of the rotating rod 73 inside the movable groove 71. A turbine 75 meshing with the worm gear 74 is provided inside the movable groove 71, and guide grooves 76 are provided on both sides of the groove. Furthermore, guide blocks 77 are inserted inside the guide groove 76, and support rods 78 are fixedly connected to the side of the two sets of guide blocks 77 that are close to each other. The support rods 78 are connected to the turbine 75 through a rotating shaft, and support blocks 79 are connected to the outer surfaces of the two ends of the support rods 78 by bearings. The top of the support block 79 is fixedly connected to the first moving frame 710, and the second moving frame 711 is provided inside the movable groove 71 on the other side. This design, through the action of the two sets of guide blocks 77, can keep the support rods 78 at the same horizontal height, so that the turbine 75 and the worm gear 74 are always engaged, and the first moving frame 710 can be more stable during movement.

[0032] The internal dimensions of the guide groove 76 are adapted to the external dimensions of the guide block 77. The external dimensions of the first moving frame 710 and the second moving frame 711 are adapted to the internal dimensions of the two sets of movable grooves 71, respectively. This design makes the guide block 77 move more stably inside the guide groove 76 and keeps the guide block 77 in a uniform horizontal position. Furthermore, since the external dimensions of the first moving frame 710 and the second moving frame 711 are adapted to the internal dimensions of the top of the movable groove 71, the first moving frame 710 and the second moving frame 711 are more stable during movement.

[0033] Working principle: Before using the equipment, the mobile trolley is pushed from the inclined surface of the base plate 1 to the surface of the base plate 1. When the moving wheels at both ends of the bottom side of the mobile trolley are respectively engaged inside the first moving frame 710 and the second moving frame 711, the second motor 72 is started, which drives the rotating rod 73 to rotate, causing the worm gear 74 on the outer surface of the rotating rod 73 to rotate accordingly. Because the worm gear 75 meshes with the worm gear 74, it can drive the guide blocks 77 on both sides of the worm gear 75 to move synchronously. At this time, under the support of the support block 79, the first moving frame 710 is driven inside the movable groove 71. The top position moves to one side, and drives the second moving frame 711 to move synchronously until the first moving frame 710 and the second moving frame 711 move to the bottom position of one side of the top of the movable slot 71, and then the second motor 72 stops. This design allows the mobile trolley to be easily driven by the first moving frame 710 and the second moving frame 711 when it is pushed to one side of the surface of the base plate 1, which saves manpower and performs positioning operation on the mobile trolley to prevent it from shifting during the detection process. Conversely, by performing the above operation, the mobile trolley can be easily removed from the surface of the base plate 1.

[0034] During equipment use, starting the first motor 31 drives the first lead screw 32 to rotate, causing the moving block 33 to move on the outer surface of the first lead screw 32. Under the action of the second lead screw 36, the slider 35 moves synchronously on the outer surface of the slide bar 34. At this time, the horizontal longitudinal movement distance of the entire displacement structure 4 between the two sets of mounting brackets 2 can be controlled. Then, starting the drive motor 42 drives the first bevel gear 43 to rotate. Because the first bevel gear 43 and the second bevel gear 44 are meshed, the second bevel gear 44 can be driven to rotate, causing the moving plate 41 to move back and forth on the outer surface of the second lead screw 36, thereby controlling the horizontal movement distance of the bottom optical microscope body 5. At this time, the position of the optical microscope body 5 can be adjusted according to different detection conditions, so that the optical microscope body 5 is always in the best and most suitable detection position. After the surface detection of the solid-state battery electrode is completed, the solid-state battery electrode is charged and discharged. At this time, multiple sets of temperature detectors 6 can be used to monitor the temperature changes generated by the solid-state battery electrode during the detection process to assess whether there are internal defects such as short circuits or unevenness. The above is the complete working principle of this utility model.
