[0001] The utility model relates to the technical field of cell extrusion, in particular to a high-rate cell extrusion device. Background Technique

[0002] By extruding high-rate cells, physical changes such as deformation and expansion are likely to occur in the internal pole pieces and diaphragms of the cells, and the electrolyte will also flow accordingly, so that the substances inside the cells are evenly distributed, improving the consistency and stability of the cells. Since the numerical values of the length and width changes of high-rate cells of different specifications may be inconsistent, for this situation, the required propulsion amounts of cylinder-like devices in the front-back axial direction and the left-right axial direction fixed on the platform will be inconsistent, thus affecting the accuracy and uniformity of the extrusion process. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a high-rate cell extrusion device to solve the problem that the inconsistent propulsion amounts required by cylinder-like devices may lead to the accuracy and uniformity of the extrusion process for high-rate cells of different specification types with non-equal-proportion scaling in the front and back as mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A high-rate cell extrusion device includes a workbench and a rate cell module placed in the middle of the top surface of the workbench. Four extrusion components for extruding the peripheries of multiple-specification rate cell modules are installed on the top of the workbench, and an adjustment component for controlling the linear sliding of the extrusion components along the workbench is installed on the workbench.

[0005] Four notches are respectively opened at the top of the workbench below the middle parts of the extrusion components.

[0006] The adjustment component includes a threaded rod rotatably installed inside the notch. A slider structure is thread sleeved on the outer surface of the threaded rod. Elastic structures for driving two opposite extrusion components to adjust the distance when the threaded rod rotates are installed on both sides of the slider structure.

[0007] Preferably, a number of chutes are opened at the top of the workbench below the four extrusion components, and one end of each chute extends to the side of the workbench.

[0008] Preferably, the extrusion component includes a fixed frame plate placed on the top surface of the workbench. Two through grooves adapted to the elastic structure are opened at the bottom wall of the fixed frame plate. L-shaped fitting strips adapted to the chutes are installed on both sides of the bottom of the fixed frame plate.

[0009] Preferably, a distance sensor for monitoring the moving distance when the threaded rod rotates is installed on the slider structure, and an audible alarm electrically connected to the distance sensor is installed on the slider structure.

[0010] Preferably, the elastic structure comprises a vertical tube installed on the side of the slider structure, a spring is installed inside the vertical tube, and a connecting cylinder for passing through the through slot is connected to the top of the spring.

[0011] Preferably, a cylinder structure is installed on the fixed frame plate, and an extrusion plate that fits the outer side of the rate battery cell module is installed on the free end of the cylinder structure.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, for a rate cell module with two front and rear specifications and inconsistent length and width values in the size change, the position of the corresponding extrusion assembly on the workbench can be adjusted by rotating the threaded rod for setting the orientation, so as to ensure that the distance between the free end of the extrusion assembly around the rate cell module and the outer side of the rate cell module is consistent when it is not advanced, thereby ensuring the accuracy and consistency of the extrusion process and improving the uniformity and effect of the extrusion.

[0014] 2. In the utility model, by plugging the extrusion assembly into the slide groove on the top of the workbench, and when the through groove on the fixed frame plate moves to the top of the connecting cylinder, the spring uses its own elasticity and reset performance to restore the original state upward while driving the connecting cylinder to extend upward and pass through the inside of the through groove, thereby realizing the screwless assembly operation of the extrusion assembly, and the disassembly and assembly are relatively convenient and easy to use.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] For high-rate battery cells of different specifications, the numerical values of the changes in their length and width dimensions may be inconsistent. In view of this situation, the required propulsion amounts of the cylinder-like devices fixed on the platform in the front-back axial direction and the left-right axial direction will be inconsistent. In order to effectively solve this problem. Please refer to Figures 1 - 4 A high-rate battery cell extrusion device provided by the present invention includes a workbench 1 and a rate battery cell module 2 placed in the middle of the top surface of the workbench 1. Four extrusion components 3 installed on the top of the workbench 1 are used to extrude the periphery of the rate battery cell module 2 of various specifications. An adjustment component 4 installed on the workbench 1 controls the extrusion component 3 to linearly slide along the workbench 1, so as to additionally provide some space required for adjustment on the original adjustment range of the extrusion component 3.

[0022] Specifically, as shown in Figure 1 and 4 The top of the workbench 1 is provided with four notches 101 respectively located below the middle of the extrusion components 3. The adjustment component 4 includes a threaded rod 401 rotatably installed inside the notch 101. A slider structure 402 is threadedly sleeved on the outer surface of the threaded rod 401. Elastic structures 403 installed on both sides of the slider structure 402 extend upward into the interior of the extrusion component 3, and are used to drive the two opposite extrusion components 3 to adjust the distance when the threaded rod 401 rotates. When the length and width numerical values of the front and back two specifications and the specification sizes change are inconsistent in the extrusion device, rotate the threaded rod 401 in the corresponding direction, so that the slider structure 402 moves along the corresponding side of its outer surface, thereby driving the extrusion component 3 connected through the elastic structure 403 to move along the top surface of the workbench 1 accordingly, so that the distance between one end of the extrusion component 3 in this direction before propulsion and the rate battery cell module 2 is adjusted to be the same as the distance between the free end of the adjacent extrusion component 3 and the rate battery cell module 2, so as to make the extrusion forces received by the periphery of the rate battery cell module 2 consistent during actual testing, and ensure the accuracy and consistency of the extrusion process.

[0023] For the convenience of disassembling and assembling the extrusion component 3 on the workbench 1, as shown in Figures 2 - 4As shown in the figure, a plurality of sliding grooves 102 are provided at the top of the workbench 1, and are respectively located below the four extrusion components 3. One end of the sliding groove 102 extends to the side of the workbench 1. The extrusion component 3 includes a fixed frame plate 301 placed on the top surface of the workbench 1. Two through grooves 3011 adapted to the elastic structure 403 are provided on the bottom wall of the fixed frame plate 301. L-shaped fitting strips 3012 adapted to the sliding grooves 102 are installed on both sides of the bottom of the fixed frame plate 301. The elastic structure 403 includes a vertical cylinder 4031 installed on the side of the slider structure 402. A spring 4032 is installed inside the vertical cylinder 4031. The top of the spring 4032 is connected to an engagement cylinder 4033 for passing through the through groove 3011. When assembling the extrusion component 3, by applying a downward extrusion force to the engagement cylinder 4033, the spring 4032 is forced to contract inward. At the same time, the engagement cylinder 4033 itself is adjusted to a state where the top is lower than the top surface of the notch 101. Subsequently, the two L-shaped fitting strips 3012 are respectively aligned with the two sliding grooves 102 and pushed to make them slide inward along the inside of the sliding grooves 102 until the through groove 3011 is directly above the engagement cylinder 4033. The extrusion force applied to the spring 4032 is cancelled. While restoring its original state, it drives the engagement cylinder 4033 to extend upward and pass through the inside of the through groove 3011, thereby realizing the screw-free assembly operation of the extrusion component 3, and both disassembly and assembly are relatively convenient and easy to operate.

[0024] When rotating the threaded rod 401 to adjust the position of the extrusion component 3 on the top surface of the workbench 1, in order to effectively avoid a large deviation between the actual moving distance and the preset distance, such as Figure 2 and Figure 4 shown, a distance sensor 4021 for monitoring the moving distance when the threaded rod 401 rotates is installed on the slider structure 402. A sound warning device 4022 electrically connected to the distance sensor 4021 is installed on the slider structure 402. While rotating the threaded rod 401 to drive the slider structure 402 to move along its surface to control the position of the extrusion component 3 on the workbench 1, the distance sensor 4021 is used to real-time monitor the distance between itself and the front inner wall of the notch 101. When the monitored distance value is consistent with the set value, the sound warning device 4022 electrically connected to it emits a specific sound to remind the staff to stop rotating the threaded rod 401, thereby improving the accuracy of the position adjustment of the extrusion component 3 to a certain extent.

[0025] As Figure 3 shown, a cylinder structure 302 is installed on the fixed frame plate 301. An extrusion plate 303 that fits against the outside of the multiple-rate battery cell module 2 is installed at the free end of the cylinder structure 302. By the extension operation of the cylinder structure 302, it is possible to control the extrusion plate 303 to extrude against the outside of the multiple-rate battery cell module 2 in the middle of the top surface of the workbench 1, thereby performing the safety test of the multiple-rate battery cell module 2.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
