Description

Technical Field

[0001] This utility model relates to the field of battery production, specifically an integrated negative pressure suction nozzle and probe. Background Technology

[0002] The post-formation and capacity testing process is a core step in lithium-ion battery production, directly affecting the battery's capacity, cycle life, and safety performance. In this process, probes and negative pressure nozzles are key pieces of equipment. Probes are used for electrical contact during battery formation and capacity testing, ensuring stable current and voltage transmission. Their gold plating and micro-toothed design reduce contact resistance, minimize heat generation, and improve testing efficiency. The negative pressure nozzle uses a negative pressure system to extract gas, preventing battery expansion and deformation.

[0003] In existing technologies, cylindrical batteries typically require the use of probes and negative pressure nozzles during processing and production to inspect the tabs and remove residual gas from the electrolyte, thereby increasing the yield rate during battery processing. However, in most existing batteries, the distance between the electrolyte inlet and the tab on the same side is too small, and the negative pressure nozzle and probe are mounted on different bases. This makes it easy for poor contact with the tab or nozzle seal failure to occur when inspecting the tab and the electrolyte inlet or removing gas. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the distance between the electrolyte filling port and the tab on the same side of most existing batteries is too small, and the negative pressure suction nozzle and probe are installed on different bases. As a result, when it is necessary to detect the tab and the electrolyte filling port or to suck air, problems such as poor contact with the tab or failure of the suction nozzle seal may easily occur. This utility model proposes an integrated negative pressure suction nozzle and probe.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an integrated negative pressure suction nozzle and probe, including a fixed base, a current probe and a voltage probe fixedly connected to the inner cavity of the fixed base, a negative pressure suction rod fixedly connected to the inner cavity of the fixed base, a suction nozzle fixedly connected to one end of the negative pressure suction rod, a rubber tube fixedly connected to the inner cavity of the negative pressure suction rod, a temperature probe fixedly connected to the inner cavity of the fixed base, an installation hole opened on the top of the fixed base, and an installation mechanism provided on the top of the fixed base.

[0006] Preferably, the mounting mechanism includes a fixing plate, the bottom of which is fixedly connected to the top of a fixing base, a movable plate slidably connected to the top of the fixing plate, a rotating rod rotatably connected to the inner cavity of the movable plate, a fixing block fixedly connected to the top of the fixing plate, a clamping block rotatably connected to the inner cavity of the fixing block, a connecting shaft rotatably connected to the inner cavity of the clamping block, and the inner cavity of the rotating rod rotatably connected to the surface of the connecting shaft.

[0007] Preferably, a reinforcing rod is rotatably connected to the inner cavity of the movable plate, and the surface of the reinforcing rod is rotatably connected to the inner cavity of the rotating rod.

[0008] Preferably, a screw is rotatably connected to one side of the fixed block, and the surface of the screw is threadedly connected to the inner cavity of the moving plate.

[0009] Preferably, the top of the fixed plate has a limiting groove, and the bottom of the movable plate is fixedly connected to a limiting block, the surface of the limiting block being slidably connected to the inner cavity of the limiting groove.

[0010] Preferably, a fixing rod is fixedly connected to the inner cavity of the limiting groove, and the surface of the fixing rod is slidably connected to the inner cavity of the limiting block.

[0011] Preferably, a rubber block is movably bonded to one side of the clamping block, and two rubber blocks are provided, with the two rubber blocks having the same thickness.

[0012] The advantages of this utility model are:

[0013] This invention allows the current and voltage probes to detect the voltage and current of the battery tabs by moving the fixed base. The suction nozzle can adsorb gas from the electrolyte. Simultaneously, the rotation of the screw smoothly moves the moving plate, which in turn drives the clamping block to rotate, thus clamping and installing additional current probes. This not only increases the stability of the current probes, voltage probes, and suction nozzle during use, improving contact stability and sealing during adsorption, but also makes the installation and testing of additional current probes convenient. This expands the range of detectable current values ​​and solves the problems of insufficient distance between the electrolyte inlet and the tab on the same side in most existing batteries, and the separate mounting of the negative pressure suction nozzle and probe on different bases, which easily leads to poor contact with the tab or suction nozzle seal failure when testing or aspirating the electrolyte inlet.

[0020] 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 scope of protection of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses an integrated negative pressure suction nozzle and probe. (Refer to...) Figure 1 and Figure 2 An integrated negative pressure suction nozzle and probe includes a fixed base 5, a current probe 3 and a voltage probe 6 fixedly connected to the inner cavity of the fixed base 5, a negative pressure suction rod 2 fixedly connected to the inner cavity of the fixed base 5, a suction nozzle 7 fixedly connected to one end of the negative pressure suction rod 2, a rubber tube 1 fixedly connected to the inner cavity of the negative pressure suction rod 2, a temperature probe 4 fixedly connected to the inner cavity of the fixed base 5, a mounting hole 8 opened on the top of the fixed base 5, and a mounting mechanism 9 provided on the top of the fixed base 5.

[0023] The fixed base 5 enables the installation and fixation of the negative pressure suction rod 2, the current probe 3, and the voltage probe 6. The current probe 3 and the voltage probe 6 enable the detection of the battery tabs. The negative pressure suction rod 2 connects and fixes the rubber tube 1 and the suction nozzle 7, allowing the rubber tube 1, the suction nozzle 7, and the negative pressure suction rod 2 to work together to extract residual gas in the electrode liquid, increasing the yield of the battery during processing. The temperature probe 4 monitors the temperature of the cylindrical battery during testing. The current probe 3, the voltage probe 6, and the negative pressure suction rod 2 are all existing technologies in this field, so they will not be described in detail here.

[0024] Reference Figure 2 and Figure 3 The mounting mechanism 9 includes a fixed plate 901, the bottom of which is fixedly connected to the top of the fixed base 5. A movable plate 902 is slidably connected to the top of the fixed plate 901. A rotating rod 903 is rotatably connected to the inner cavity of the movable plate 902. A fixed block 904 is fixedly connected to the top of the fixed plate 901. A clamping block 905 is rotatably connected to the inner cavity of the fixed block 904. A connecting shaft 906 is rotatably connected to the inner cavity of the clamping block 905. The inner cavity of the rotating rod 903 is rotatably connected to the surface of the connecting shaft 906. The fixed base 5 can connect and install the movable plate 902 and the fixed block 904 through the fixed plate 901. The movable plate 902 can connect to the rotating rod 903, while the fixed block 904 can connect to the clamping block 905. The connecting shaft 906 installed inside the clamping block 905 can smoothly connect to and limit the rotating rod 903.

[0025] Furthermore, since the top of the movable plate 902 is slidably connected to the top of the fixed plate 901, when the movable plate 902 slides on the top of the fixed plate 901, it can smoothly push or pull the rotating rod 903. The rotating rod 903 can drive the clamping block 905 to rotate through its connection with the connecting shaft 906. After the clamping block 905 rotates to a certain angle, it can connect and fix the additional current probe 3 that needs to be installed. This allows the current probe 3 to detect a larger current value, thereby reducing costs to a certain extent. The negative pressure suction rod 2 and the suction nozzle 7 are located in the center of the fixed base 5.

[0026] Reference Figure 3 and Figure 4 A reinforcing rod 15 is rotatably connected to the inner cavity of the movable plate 902. The surface of the reinforcing rod 15 is rotatably connected to the inner cavity of the rotating rod 903. The reinforcing rod 15 can limit the rotation rod 903 through its connection with the movable plate 902, making the connection between the rotating rod 903 and the movable plate 902 more stable and less prone to shaking or unstable connection when the rotating rod 903 rotates or the movable plate 902 moves.

[0027] Reference Figure 3 and Figure 4 A screw 10 is rotatably connected to one side of the fixed block 904. The surface of the screw 10 is threadedly connected to the inner cavity of the movable plate 902. The screw 10 can smoothly drive the movable plate 902 to move when it rotates through the threaded connection between itself and the movable plate 902, as well as the sliding connection between the movable plate 902 and the top of the fixed plate 901, thereby making the movement operation of the movable plate 902 more convenient and simple.

[0028] Reference Figure 3 and Figure 4 The top of the fixed plate 901 has a limiting groove 11, and the bottom of the movable plate 902 is fixedly connected to a limiting block 12. The surface of the limiting block 12 is slidably connected to the inner cavity of the limiting groove 11. The setting of the limiting groove 11 and the limiting block 12 can effectively increase the stability of the movable plate 902 when sliding on the top of the fixed plate 901, so that when the movable plate 902 moves on the top of the fixed plate 901 by the rotation of the screw 10, it can move more stably and is less likely to rotate or shake slightly due to the rotation of the screw 10.

[0029] Reference Figure 3 A fixing rod 13 is fixedly connected to the inner cavity of the limiting groove 11. The surface of the fixing rod 13 is slidably connected to the inner cavity of the limiting block 12. The fixing rod 13 can limit the limiting block 12, so that the limiting block 12 can limit the moving plate 902 through the connection between itself and the limiting groove 11, while the limiting block 12 itself has high stability.

[0030] Reference Figure 2 and Figure 4 A rubber block 14 is movably bonded to one side of the clamping block 905. Two rubber blocks 14 are provided, and the two rubber blocks 14 have the same thickness. The rubber blocks 14 not only increase the friction between the clamping block 905 and the surface of the additionally installed current probe 3, but also reduce the wear on the surface of the additional current probe 3 when it is installed. Furthermore, the fact that the two rubber blocks 14 have the same thickness makes it less likely that the clamping force will be different or the clamping effect will be poor when the rubber blocks 14 clamp and install the additional current probe 3 due to the difference in thickness.

[0031] Working Principle: During use, the operator can move the fixed base 5, which in turn moves the suction nozzle 7, voltage probe 6, and current probe 3. This allows for the detection of current and voltage at the battery tabs and the extraction of gas from the electrolyte. When a new current probe 3 needs to be installed, the operator inserts it into the mounting hole 8 and then rotates the screw 10. The screw 10 then moves the moving plate 902, which in turn pushes the rotating rod 903. The rotating rod 903, through its connection with the clamping block 905, pushes the clamping block 905, allowing it to rotate around its connection point with the fixed block 904. This clamps and secures the additional current probe 3, making it easy to install and remove, not only for current detection at the tabs.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
