[0039] The inventors found in their research that in the production line of battery cells, the oxidation problem of battery cells will affect the production yield and production efficiency of battery cells. Therefore, how to overcome the above problem has become one of the technical problems that need to be solved urgently at this stage.

[0040] In view of this, the utility model provides a device for improving battery cell oxidation, which protects the battery cell through a sealing cover to improve the battery cell oxidation problem, thereby facilitating the improvement of the production yield of the battery cell and the improvement of production efficiency.

[0041] The following is a detailed description with reference to the accompanying drawings and specific embodiments.

[0042] Figure 1 FIG. 1 is a schematic diagram showing a connection of a device for improving oxidation of a battery cell provided in an embodiment of the present application. Figure 2 FIG. 1 is a schematic diagram of a device for improving oxidation of a battery cell provided in an embodiment of the present application. Please refer to FIG. Figure 1 and Figure 2 , the embodiment of the present application provides a device 100 for improving oxidation of a battery cell, comprising a bottom plate 10, a small box material rack 20, a sealing cover 30, a telescopic cylinder 40, a controller 50, a sensing probe 60 and a vacuum machine 70;

[0043] The small box material rack 20 is fixed to one side of the base plate 10, the material box is placed on the small box material rack 20, the battery cells are placed in the material box, the sealing cover 30 is located on the side of the small box material rack 20 away from the base plate 10, the sealing cover 30 and the telescopic cylinder 40 are detachably connected, the controller 50 is electrically connected to the telescopic cylinder 40 and the vacuum machine 70 respectively, and the controller 50 is communicatively connected to the induction probe 60.

[0044] It should be noted that the drawings in this application are for illustration only and do not represent their actual size and actual structure. Figure 2In the figure, the telescopic cylinder 40, the controller 50, the induction probe 60 and the vacuum machine 70 are all illustrated by quadrilaterals, which do not represent their actual structures. It should also be noted that the figure only illustrates the structure of the device 100 for improving the oxidation of battery cells, and does not show the material box and battery cells. The material box is located on the small box material rack 20, and the battery cells are located in the material box.

[0045] Specifically, the present application provides a device 100 for improving the oxidation of battery cells, and the device 100 for improving the oxidation of battery cells includes a bottom plate 10, a small box material rack 20, a sealing cover 30, a telescopic cylinder 40, a controller 50, an induction probe 60 and a vacuum machine 70, wherein the small box material rack 20 is arranged on the bottom plate 10, and a material box is arranged on the small box material rack 20, and the material box is used to hold battery cells. The present application sets a sealing cover 30 and a telescopic cylinder 40, and the sealing cover 30 is detachably connected to the telescopic cylinder 40, and the telescopic cylinder 40 drives the sealing cover 30 to move. When the environment in which the battery cells are located is prone to oxidation of the battery cells, the sealing cover 30 covers the small box material rack 20, and the battery cells in the material box are protected, which is conducive to improving the problem of battery cell oxidation. The present application also provides a controller 50, a sensing probe 60 and a vacuum machine 70. The controller 50 is electrically connected to the telescopic cylinder 40 and the vacuum machine 70 respectively. The sensing probe 60 and the controller 50 are in communication connection. The sensing probe 60 monitors environmental data in real time and transmits the environmental data to the controller 50. When the monitored environmental data is abnormal (prone to oxidation of the battery cells), the controller 50 controls the telescopic cylinder 40 to work, and the telescopic cylinder 40 drives the sealing cover 30 to move. The sealing cover 30 and the bottom plate 10 are buckled together to protect the small box material rack 20 in the sealing cover 30. After the sealing cover 30 and the bottom plate 10 are buckled together, the vacuum machine 70 extracts the air and water vapor in the sealing cover 30, which is beneficial to improving the problem of battery cell oxidation in the small box material rack 20.

[0046] It is understandable that in the device 100 for improving the oxidation of battery cells provided in the present application, the induction probe 60 can monitor the environment and transmit the monitored data to the controller 50. When the controller 50 finds that the monitored environmental data is abnormal, the controller 50 controls the telescopic cylinder 40 to work, and the telescopic cylinder 40 drives the sealing cover 30 to move. The sealing cover 30 and the bottom plate 10 are buckled to protect the battery cells. Such a setting is conducive to timely response to abnormal environments, thereby helping to improve the problem of battery cell oxidation, and then helping to improve the production yield of battery cells. On the other hand, the device 100 for improving the oxidation of battery cells provided in the present application is conducive to isolating a single or a certain area of ​​the small box material rack 20, protecting the battery cells on the small box material rack 20, and reducing the impact on the overall production line, thereby helping to improve production efficiency.

[0047] It should be noted that the sealing cover 30 and the telescopic cylinder 40 are detachably connected, so that the sealing cover 30 can be easily disassembled for cleaning, which is beneficial to keep the sealing cover 30 clean, and further beneficial to protect the battery cells on the small box material rack 20. The telescopic cylinder 40 is a cylinder that can drive the sealing cover 30 to move. For example, the model 32 (200*300) produced by Hongyang can be used. This application is only used as an example for illustration and is not limited to this. It should also be noted that the sealing cover 30 can be a transparent or translucent material, such as the sealing cover 30 is made of acrylic (plexiglass). The acrylic material has the advantages of being not easy to break, light weight, good stability, easy to replace, and low cost, but this application is only used as an example for illustration and is not limited to this. The vacuum machine 70 is a machine that can extract air and water vapor from the relatively closed space formed by the sealing cover 30 and the base plate 10, such as a vacuum pump. This application is not limited to this, and it can achieve specific functions.

[0048] Please refer to Figure 2 The present application provides an optional implementation mode, wherein the sealing cover 30 includes a receiving chamber 31 and a receiving chamber entrance 32, the receiving chamber entrance 32 faces the bottom plate 10, and the device 100 for improving the oxidation of the battery cell includes an open state and a closed state. When the device 100 for improving the oxidation of the battery cell is in the open state, the sealing cover 30 is separated from the bottom plate 10, and the small box material rack 20 is located outside the receiving chamber 31; when the device 100 for improving the oxidation of the battery cell is in the closed state, the sealing cover 30 and the bottom plate 10 are buckled to form a closed space, and the small box material rack 20 is located in the closed space;

[0049] The induction probe 60 is located on the side of the bottom plate 10 close to the small box material rack 20; the controller 50 and the vacuum machine 70 are both located on the side of the bottom plate 10 away from the small box material rack 20;

[0050] The bottom plate 10 includes a first through hole 11 , which penetrates the bottom plate 10 along a first direction D1 . The vacuum machine 70 is connected to the first through hole 11 via a pipe 71 . The first direction D1 is a thickness direction of the bottom plate 10 .

[0051] It should be noted that this application Figure 2 Shown is a schematic diagram of the open state of the device 100 for improving battery cell oxidation. The present application does not show the covered state of the device 100 for improving battery cell oxidation. When the device 100 for improving battery cell oxidation is in the covered state, the sealing cover 30 and the bottom plate 10 are buckled together to form an enclosed space, and the small box material rack 20 is located in the enclosed space.

[0052] Specifically, in the device 100 for improving battery cell oxidation in this embodiment, the sealing cover 30 includes a accommodating chamber 31, and an accommodating chamber entrance 32 is provided on a side of the accommodating chamber 31 close to the bottom plate 10, and the accommodating chamber entrance 32 is an entrance for the small box material rack 20 to enter the accommodating chamber 31. The device 100 for improving battery cell oxidation provided in the present application includes an open state and a covered state. The device 100 for improving battery cell oxidation includes a sensing probe 60, which can monitor environmental data in real time. When the data monitored by the sensing probe 60 is normal, the device 100 for improving battery cell oxidation is in an open state, the sealing cover 30 and the bottom plate 10 are separated, and the small box material rack 20 is located outside the accommodating cavity 31; when the data monitored by the sensing probe 60 is abnormal, that is, when it is monitored that the environment is likely to cause battery cell oxidation, the device 100 for improving battery cell oxidation is changed from an open state to a covered state, and the telescopic cylinder 40 moves under the control of the controller 50, and the telescopic cylinder 40 drives the sealing cover 30 to move, and the sealing cover 30 and the bottom plate 10 are buckled to form a closed space, and the small box material rack 20 is located in the closed space, so that the battery cells in the small box material rack 20 are protected in time, which is beneficial to improving the battery cell oxidation problem, and further beneficial to improving the battery cell production yield.

[0053] In order to facilitate the sensing probe 60 to monitor environmental data, the present embodiment sets the sensing probe 60 on the side of the bottom plate 10 close to the small box material rack 20, and the sensing probe 60 is set on the side of the bottom plate 10 close to the small box material rack 20. The environmental data monitored by the sensing probe 60 is closer to the environment in which the battery cell is located, and the monitored data is more accurate, which is more conducive to timely protecting the battery, thereby helping to improve the battery cell oxidation problem, and further helping to improve the battery cell production yield.

[0054] At the same time, the present application sets a first through hole 11 on the bottom plate 10, and the vacuum machine 70 is connected to the first through hole 11 through a pipe 71. The air and water vapor in the enclosed space are extracted by the vacuum machine 70, so that the battery cells on the small box material rack 20 are in a vacuum environment, which is further beneficial to improve the battery cell oxidation problem.

[0055] It should be noted that in the drawings of the present application, the sealing cover 30 is in the shape of a rectangular parallelepiped, but the present application is not limited thereto and can be designed according to actual needs to enable the small box material rack 20 and the bottom plate 10 to be snapped together and opened, and to protect the battery cells when snapped together.

[0056] Please continue to refer to Figure 2 Optionally, a filter screen 80 is further included. The filter screen 80 is located in the accommodating chamber 31 . The filter screen 80 is parallel to the plane where the accommodating chamber inlet 32 ​​is located. The filter screen 80 is at least arranged on one side wall of the sealing cover 30 .

[0057] Specifically, the device 100 for improving battery cell oxidation provided in the present application is further provided with a filter 80 in the accommodating chamber 31 of the sealing cover 30. The filter 80 is parallel to the plane where the entrance 32 of the accommodating chamber is located. The filter 80 avoids the space of the small box material rack 20 and is arranged on at least one side wall of the sealing cover 30. The present application provides an optional implementation method in which the filter 80 is arranged around the inner wall of the sealing cover 30. With such an arrangement, when the device 100 for improving battery cell oxidation is changed from an open state to a closed state, the air entering the accommodating chamber 31 is filtered by the filter 80, which is beneficial to filtering part of the dust in the sealing cover 30, and further beneficial to protecting the battery cells. At the same time, when the device 100 for improving battery cell oxidation is in the closed state, when the vacuum machine 70 draws out the air in the sealing cover 30, it can filter the dust in the sealing cover 30 again, which is beneficial to reducing the impact of dust on the battery cells, thereby further beneficial to protecting the battery cells and further beneficial to improving the production yield of the battery cells.

[0058] It should be noted that, taking the rectangular sealing cover 30 as an example, when the filter 80 is only arranged on part of the side wall of the sealing cover 30, the filter 80 is preferably arranged on the two side walls with larger areas. In this way, the area of ​​the filter 80 is larger and the filtering effect is relatively better. It should also be noted that the function of the filter 80 is to filter dust, so the filter 80 needs to be cleaned and replaced regularly.

[0059] Please continue to refer to Figure 2 Optionally, along the first direction D1, the minimum distance between the filter screen 80 and the accommodating chamber entrance 32 is H, 40cm≤H≤60cm.

[0060] Specifically, the device 100 for improving battery cell oxidation provided in the present application includes a filter screen 80, and the filter screen 80 is parallel to the entrance 32 of the accommodating chamber. Along the first direction D1, the minimum distance between the filter screen 80 and the entrance 32 of the accommodating chamber is H. When the minimum distance H between the filter screen 80 and the entrance 32 of the accommodating chamber is less than 40 cm, the distance between the filter screen 80 and the entrance 32 of the accommodating chamber is too close, that is, the distance between the filter screen 80 and the first through hole 11 is too close, which is not conducive to filtering dust in the sealing cover 30 and may affect the operation of the vacuum machine 70; when the minimum distance H between the filter screen 80 and the entrance 32 of the accommodating chamber is greater than 60 cm, the minimum distance between the filter screen 80 and the entrance 32 of the accommodating chamber is too large, which is not conducive to filtering dust in the sealing cover 30; therefore, the minimum distance H between the filter screen 80 and the entrance 32 of the accommodating chamber is set to 40 cm ≤ H ≤ 60 cm. Such a setting is beneficial to reducing the impact on the operation of other structures in the device and filtering dust in the sealing cover 30. The present application provides an optional implementation manner, in which the minimum distance H between the filter net 80 and the entrance 32 of the accommodating chamber is 42 cm; the present application provides another optional implementation manner, in which the minimum distance H between the filter net 80 and the entrance 32 of the accommodating chamber is 50 cm; the present application provides another optional implementation manner, in which the minimum distance H between the filter net 80 and the entrance 32 of the accommodating chamber is 58 cm; the present application provides another optional implementation manner, in which the minimum distance H between the filter net 80 and the entrance 32 of the accommodating chamber is set to 45 cm ≤ H ≤ 55 cm.

[0061] Please continue to refer to Figure 2 , the present application provides an optional implementation method, which further includes an anti-collision strip, which is arranged around the material box, and the material of the anti-collision strip includes fluororubber or polytetrafluoroethylene. It should be noted that the material box and the anti-collision strip are not shown in the drawings of the present application. The anti-collision strip is to prevent the battery cell from colliding and breaking, so the anti-collision strip is arranged around the material box.

[0062] Specifically, in the present embodiment, the device 100 for improving the oxidation of battery cells further includes an anti-collision strip, which is arranged around the material box on the small box material rack 20. Optionally, the material of the anti-collision strip includes fluororubber, or the material of the anti-collision strip includes polytetrafluoroethylene. Fluororubber is a synthetic polymer elastomer with excellent heat resistance, oxidation resistance and corrosion resistance, and polytetrafluoroethylene is a polymer with excellent heat resistance and cold resistance. The present application arranges an anti-collision strip around the material box, and uses fluororubber or polytetrafluoroethylene as the material of the anti-collision strip, which is beneficial to prevent the battery cells from being broken due to collisions, thereby helping to improve the production yield of the battery cells. At the same time, the two materials, fluororubber and polytetrafluoroethylene, are not easily affected by the environment in abnormal environments such as high temperature and high humidity, which is beneficial to improving the structural stability of the device 100 for improving the oxidation of battery cells.

[0063] Please continue to refer to Figure 2 The present application provides an optional implementation in which the sensing probe 60 includes a temperature sensor, and the temperature sensor is communicatively connected to the controller 50 .

[0064] Specifically, the device 100 for improving battery cell oxidation provided in the present application includes a sensing probe 60, which monitors environmental data in real time. In the present embodiment, the sensing probe 60 includes a temperature sensor, which monitors temperature data in real time. A high temperature environment will affect the oxidation of the battery cell. Therefore, a temperature sensor is provided in the present embodiment to monitor temperature data in real time. The temperature sensor is communicated with the controller 50, and the temperature sensor transmits the monitored data to the controller 50. When the controller 50 finds that the temperature exceeds a preset range, the telescopic cylinder 40 drives the sealing cover 30 to move, and the device 100 for improving battery cell oxidation is changed from an open state to a covered state. The vacuum machine 70 extracts air and water vapor in the sealing cover 30 to isolate the battery cell, which is beneficial to protecting the battery cell, improving the problem of battery cell oxidation, and further beneficial to improving the battery cell production yield.

[0065] Please continue to refer to Figure 2 The present application provides an optional implementation scheme in which the sensing probe 60 includes a humidity sensor, and the humidity sensor is communicatively connected to the controller 50 .

[0066] Specifically, the device 100 for improving battery cell oxidation provided in the present application includes a sensing probe 60, which monitors environmental data in real time. In the present embodiment, the sensing probe 60 includes a humidity sensor, which monitors humidity data in real time. In an environment with high humidity, the oxidation of the battery cell will also be affected. Therefore, a humidity sensor is provided in the present embodiment, and the humidity data is monitored in real time by the humidity sensor. The humidity sensor is communicated with the controller 50, and the humidity sensor transmits the monitored data to the controller 50. When the controller 50 finds that the humidity exceeds the preset range, the telescopic cylinder 40 drives the sealing cover 30 to move, and the device 100 for improving battery cell oxidation is changed from an open state to a covered state. The vacuum machine 70 extracts the air and water vapor in the sealing cover 30 to isolate the battery cell, which is beneficial to protecting the battery cell, improving the problem of battery cell oxidation, and further beneficial to improving the battery cell production yield.

[0067] Please continue to refer to Figure 2 Optionally, the sensing probe 60 includes a cleanliness probe, and the cleanliness probe is communicatively connected to the controller 50 .

[0068] Specifically, the device 100 for improving battery cell oxidation provided in the present application includes a sensing probe 60, which monitors environmental data in real time. In the present embodiment, the sensing probe 60 includes a cleanliness probe, which monitors cleanliness data in real time. The cleanliness of the environment in which the battery cell is located will also affect the oxidation of the battery cell. Therefore, a cleanliness probe is provided in the present embodiment, and the cleanliness data is monitored in real time by the cleanliness probe. The cleanliness probe is communicated with the controller 50, and the cleanliness probe transmits the monitored data to the controller 50. When the controller 50 finds that the cleanliness exceeds a preset range, the telescopic cylinder 40 drives the sealing cover 30 to move, and the device 100 for improving battery cell oxidation is changed from an open state to a covered state. The vacuum machine 70 extracts the air and water vapor in the sealing cover 30 to isolate the battery cell, which is beneficial to protecting the battery cell, improving the problem of battery cell oxidation, and further beneficial to improving the battery cell production yield.

[0069] It should be noted that the controller 50 of the present application determines whether the data is within the data range of a normal environment through the data signal transmitted by the sensing probe 60. The present application takes the sensing probe 60 including a temperature sensor, a humidity sensor and a cleanliness sensor as an example for explanation. When the data monitored by the temperature sensor exceeds 25°C, or the data monitored by the humidity sensor exceeds 60%, or the data monitored by the cleanliness sensor exceeds 35200 particles / m 3 When the controller 50 transmits a downward movement signal to the telescopic cylinder 40, the sealing cover 30 and the bottom plate 10 are closed, and the vacuum machine 70 extracts the air and water vapor in the sealing cover 30. This application only uses this as an example for illustration and is not limited to this. In actual use, it can be designed according to the usage situation. This application provides another optional implementation method, in which the controller 50 is a programmable logic controller, for example, the controller 50 is a PLCs7-200 programmable controller. In this implementation, a PLC program can be loaded into the controller 50 to realize control. In this application, the control process of the telescopic cylinder 40 and the vacuum machine 70 by the controller 50 can adopt the control method of the prior art. This application does not improve the control method, and the technical effect is not based on the control method. At the same time, this application is not based on the control program. This application only uses this as an example for illustration and is not limited to this.

[0070] It should also be noted that the present application provides three situations in which the sensing probe 60 includes a temperature sensor, a humidity sensor or a cleanliness sensor, but this does not mean that the sensing probe 60 can only include one of the temperature sensor, the humidity sensor and the cleanliness sensor. It can also include multiple temperature sensors, humidity sensors and cleanliness sensors, and can also include other sensing probes, such as a pressure sensor for detecting pressure, which can be selected according to actual conditions, and the present application is not limited to this.

[0071] Please continue to refer to Figure 2 The present application provides an optional implementation manner, which further includes a gas pipeline, the gas pipeline is located on the small box material rack 20, the bottom plate 10 includes a second through hole, the second through hole penetrates the bottom plate 10 along a first direction D1, the second through hole is connected to the gas pipeline, and the first direction D1 is the thickness direction of the bottom plate 10.

[0072] It should be noted that the gas pipeline and the second through hole are not shown in the drawings of the present application. The gas pipeline is arranged on the small box material rack 20. The second through hole is similar to the first through hole 11. The gas enters the accommodating cavity 31 of the sealing cover 30 through the second through hole and the gas pipeline.

[0073] Specifically, in this embodiment, the small box material rack 20 also includes a gas pipeline, a second through hole is set on the bottom plate 10, the second through hole penetrates the bottom plate 10 along the first direction D1, and the gas pipeline is connected to the second through hole, that is, on the side of the bottom plate 10 away from the small box material rack 20, gas is introduced into the gas pipeline through the second through hole. Optionally, nitrogen or argon can be introduced into the gas pipeline. Nitrogen and argon are both gases with high stability and are not easy to react with battery cells. On the one hand, it is beneficial to protect the battery cells. On the other hand, when the device 100 for improving the oxidation of battery cells needs to be changed from a closed state to an open state, gas is introduced into the sealing cover 30 to facilitate the separation of the sealing cover 30 and the bottom plate 10. It should be noted that this application only takes the example of nitrogen or argon being introduced into the gas pipeline for explanation, and is not limited to this. In actual use, it can be selected according to actual conditions.

[0074] Please continue to refer to Figure 2 Optionally, the material of the base plate 10 includes one of stainless steel, iron, steel, carbon, and nanomaterials.

[0075] Specifically, as the base plate 10 of the device 100 for improving battery cell oxidation, first of all, it has the function of supporting the small box material rack 20, and at the same time it needs to form a closed space with the sealing cover 30, and it is also necessary to set a first through hole 11 connected to the vacuum machine 70 and a second through hole connected to the gas pipeline on the base plate 10. The material selection of the base plate 10 is particularly important. The present application provides an optional implementation method in which the material of the base plate 10 is stainless steel. Such a configuration is beneficial for the base plate 10 to maintain structural stability in abnormal environments such as high temperature and high humidity. Optionally, the material of the base plate 10 can be selected from 304 stainless steel or 306 stainless steel, but the present application is not limited to this. The material of the base plate 10 can maintain structural stability in abnormal environments (such as high temperature or high humidity environments). The present application provides another optional implementation manner that the material of the base plate 10 includes iron; the present application provides another optional implementation manner that the material of the base plate 10 includes steel; the present application provides another optional implementation manner that the material of the base plate 10 includes carbon, for example, carbon fiber can be used; the present application provides another optional implementation manner that the material of the base plate 10 includes nanomaterials. When nanomaterials are used as the material of the base plate 10, the probability of attenuation of the nanomaterials in a high temperature and high humidity environment is small. Even if attenuation occurs, it can be reinforced by applying nanopaint. Such a configuration is further beneficial for the base plate 10 to maintain structural stability in abnormal environments such as high temperature and high humidity.
