Description
Technical Field
[0001] This utility model relates to the technical field of solid-state battery molding equipment, specifically to a uniform film rolling device for solid-state batteries. Background Technology
[0002] Solid-state battery rolling process is a key technology for preparing solid electrolyte films. It mainly involves mechanically rolling the electrolyte material into a uniform and dense film. This process can effectively reduce interfacial impedance, improve ionic conductivity, and at the same time ensure controllable film thickness and mechanical strength.
[0003] In existing solid-state battery film rolling processes, traditional film rolling equipment usually lacks a high-precision weighing structure, making it difficult to accurately control the amount of raw materials fed in, easily generating excessive scrap, increasing material waste and production costs. At the same time, excessive raw materials can easily lead to thickness fluctuations during the rolling process, affecting the uniformity and density of the film, thereby reducing the ionic conductivity and interface stability of the solid electrolyte. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model proposes a uniform film rolling device for solid-state batteries.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:
[0006] A uniform film rolling device for solid-state batteries includes a machine base, a film rolling table and a film rolling assembly for film rolling, a film rolling plate on the film rolling table, a heating plate at the bottom of the film rolling plate, and a plurality of weighing units at the bottom of the film rolling plate.
[0007] Preferably, the rolling table is provided with an installation groove, and the weighing unit is placed in the installation groove. Through the above improvements, the weighing unit is placed in the installation groove, which improves the stability of the weighing unit installation and thus improves the weighing accuracy.
[0008] Preferably, the rolling table has an embedding groove, the heating plate is placed in the embedding groove, and the mounting slots are spaced apart on the outer periphery of the embedding groove. Through the above improvements, the heating plate is placed in the embedding groove to ensure the stability of the heating plate installation, and the mounting slots are spaced apart on the outer periphery of the embedding groove to increase the heat conduction distance when the heating plate is heated and reduce the impact on the balancing unit.
[0009] Preferably, a heat insulation ring is provided in the mounting groove, and the heat insulation ring is arranged around the outer periphery of the weighing unit. Through the above improvements, the heat insulation ring can not only increase the stability of the weighing unit, but also provide heat insulation to avoid the high temperature generated by the heating plate from affecting the calculation results.
[0010] Preferably, a weighing groove is formed at the bottom of the rolling plate, and a heat insulation seat is provided in the weighing groove. The weighing end of the weighing unit is placed in the weighing groove and abuts against the heat insulation seat.

In addition, the heat insulation pad is used to isolate heat, so as to avoid affecting the measurement accuracy of the weighing unit.
[0011] Preferably, the rolling plate is provided with a rolling support assembly, which includes a pushing unit and a support block connected to the output end of the pushing unit. When the rolling plate is weighing, the support block is away from the rolling plate. When the rolling plate is rolling, the support block is supported on the bottom of the rolling plate. Through the above improvements, damage to the weighing unit is avoided during the rolling process. When the rolling plate is rolling, the support block is supported on the bottom of the rolling plate, thereby avoiding pressure on the weighing unit from the rolling roller and improving the service life of the weighing unit.
[0012] Preferably, the film rolling assembly includes a sliding bracket, a lifting bracket slidably mounted on the sliding bracket, a transverse module for driving the sliding bracket to move, a lifting unit for driving the lifting bracket to move up and down, and a film rolling roller mounted on the lifting bracket. Through the above improvements, the transverse module and the lifting unit drive the sliding bracket and the lifting bracket to move, so that the film rolling roller rolls the raw material of the solid-state battery back and forth. Furthermore, the lifting unit can quickly adjust the height and pressure of the film rolling roller to improve the film rolling effect.
[0013] Preferably, the sliding bracket is provided with a temperature detection component, which includes a mounting plate and a temperature sensor mounted on the mounting plate, with the sensing end of the temperature sensor facing the rolling plate. Through the above improvements, the temperature on the rolling plate can be accurately detected by the temperature sensor to ensure the rolling quality.
[0014] Preferably, the rolling sheet has a cutting groove. With the above improvement, a cutting knife is placed into the cutting groove to cut the rolled-out film into a specified shape.
[0015] Preferably, a limiting plate is provided on the rolling table, and a positioning sensor is inserted into the limiting plate. The positioning sensor is positioned facing the outer periphery of the rolling table. Through the above improvements, the limiting plate can restrict the installation position of the rolling table, ensuring the stability of the rolling table installation. Furthermore, the positioning sensor can detect whether the rolling table is installed in place, preventing rolling from occurring if the rolling table is not installed in place.
[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0017] By setting several weighing units at the bottom of the rolling plate, the raw materials of the solid-state battery on the rolling plate are weighed before the rolling assembly is rolled, thus avoiding waste. After the rolling is completed, after removing the excess scrap, the rolled film is weighed again to ensure that the film is at a specified weight, thereby improving the uniformity of the rolling and further improving the quality of the solid-state battery.

[0029] like Figure 1-8 As shown, a uniform film rolling device for solid-state batteries includes a machine base 1, a film rolling table 2 on the machine base 1, and a film rolling assembly 3 for film rolling. A film rolling plate 4 is provided on the film rolling table 2, a heating plate 5 is provided at the bottom of the film rolling plate 4, and several weighing units 6 are provided at the bottom of the film rolling plate 4.
[0030] By setting several weighing units 6 at the bottom of the rolling plate 4, the raw materials of the solid battery on the rolling plate 4 will be weighed before the rolling assembly 3 rolls the film, ensuring that a certain amount of solid battery raw materials are rolled, thereby avoiding waste and reducing manufacturing costs.
[0031] Furthermore, after rolling and removing excess scrap, the rolled film is weighed again to ensure it is at a specified weight. This not only improves the uniformity of rolling the film but also ensures the quality of the solid-state battery.
[0032] like Figures 5 to 8 As shown, regarding the further explanation of the installation of the weighing unit 6 in this embodiment, the rolling table 2 is provided with an installation groove 1.1, and the weighing unit 6 is placed in the installation groove 1.1. Placing the weighing unit 6 in the installation groove 1.1 improves the stability of the installation of the weighing unit 6, thereby improving the accuracy of weighing.
[0033] Specifically, the rolling table 2 has an embedding groove 1.2, the heating plate 5 is placed in the embedding groove 1.2, the rolling plate 4 is placed above the heating plate 5, and the heating plate 5 is attached to the bottom of the rolling plate 4. The heating plate 5 is placed in the embedding groove 1.2 to ensure the stability of the installation of the heating plate 5. The mounting grooves 1.1 are distributed at intervals on the outer periphery of the embedding groove 1.2 to increase the heat conduction distance when the heating plate 5 is heated and reduce the impact on the balancing unit 6.
[0034] The rolling plate 4 is square, and the weighing unit 6 is supported at the bottom of the four corners of the rolling plate 4 to ensure the stability of the rolling plate 4.
[0035] Furthermore, a heat insulation ring 1.3 is provided in the mounting groove, and the heat insulation ring 1.3 is arranged around the outer periphery of the weighing unit 6.

The heat insulation pad is used to isolate heat to avoid affecting the measurement accuracy of the weighing unit 6.
[0037] In some other embodiments, a rolling support assembly 2.1 is provided on the rolling table 2, and the rolling support assembly 2.1 includes a pushing unit 2.2 and a support block 2.3 connected to the output end of the pushing unit 2.2. When the rolling plate 4 is weighed, the support block 2.3 moves away from the rolling plate 4. When the rolling plate 4 is rolling, the support block 2.3 supports the bottom of the rolling plate 4.
[0038] When the film is rolled on the film rolling plate 4, the support block 2.3 supports the bottom of the film rolling plate 4, which can effectively prevent damage to the weighing unit 6 during the film rolling process and prevent the weighing unit 6 from being subjected to the pressure of the film rolling roller 3.5, thereby improving the service life of the weighing unit 6.

The transverse module 3.3 and the lifting unit 3.4 drive the sliding bracket 3.1 and the lifting bracket 3.2 to move, so that the film rolling roller 3.5 rolls the raw material of the solid-state battery back and forth. The lifting unit 3.4 can quickly adjust the height and pressure of the film rolling roller 3.5 to improve the rolling effect of the film.
[0040] Among them, the machine base 1 is equipped with a slider module 3.6, and the sliding bracket 3.1 is installed on the slider module 3.6 to improve the smoothness of the sliding bracket 3.1 during the sliding process.

The temperature detection component 4.1 includes a mounting plate 4.2 and a temperature sensor 4.3 disposed on the mounting plate 4.2. The sensing end of the temperature sensor 4.3 is positioned facing the rolling plate 4. The temperature sensor 4.3 can accurately detect the temperature on the rolling plate 4 to ensure the rolling quality.
[0042] Preferably, the mounting plate 4.2 is provided with an adjustment groove 4.4 to adjust the angle of the temperature sensor 4.3, thereby ensuring the accuracy of temperature detection.
[0043] like Figure 5 , Figure 7 As shown, as a further explanation of the embodiment of the rolling sheet 4, the rolling sheet 4 has a cutting groove 5.1 formed on it. A cutting knife is placed into the cutting groove 5.1 to cut the rolled sheet into a specified shape.
[0044] Furthermore, multiple cutting grooves 5.1 are formed on the rolling plate 4, and the cutting grooves 5.1 gradually spread along the outer periphery of the rolling plate 4 to form films of different sizes.
[0045] Furthermore, a limiting plate 5.2 is provided on the rolling table 2, and a positioning sensor 5.3 is inserted on the limiting plate 5.2.
