The film rolling assembly 3 includes a film rolling roller 6, a lifting unit 7 for driving the film rolling roller 6 to move up and down, and a transverse module 8 for driving the film rolling roller 6 to move horizontally. A cooling channel 3.1 is formed inside the film rolling plate 4, which can quickly cool the film rolling plate 4, causing the film to shrink slightly, thereby making it easier to remove the cut film.

[0029] Throughout the film rolling process, the solid-state battery raw material is laid flat on the film rolling plate 4. The heating plate 5 heats up and conducts the heat to the film rolling plate 4. The downward pressure and height of the film rolling roller 6 can be adjusted by the lifting unit 7. The transverse module 8 drives the film rolling roller 6 to move back and forth, rolling the solid-state battery film laid flat on the film rolling plate 4 back and forth until the set thickness requirement is met, and then the work stops. The sliding bracket 1.1 and the lifting bracket 1.2 are used to drive the film rolling roller 6 to move, which can improve the stability of the film rolling roller 6 during the movement.

[0030] When film thickness adjustment is required, the position of the rolling roller 6 can be quickly adjusted using the lifting unit 7 to control the film thickness without manual adjustment. This not only provides high adjustment accuracy but also reduces the labor intensity of operators.

[0031] Preferably, the lifting unit 7 is an electric cylinder driven by a servo motor to ensure accuracy during the up-and-down movement.

The sliding bracket 1.1 is connected to the moving end of the transverse module 8. By using the sliding bracket 1.1 and the lifting bracket 1.2 to drive the rolling roller 6 to move, the stability of the rolling roller 6 during the movement can be improved.

[0033] The sliding bracket 1.1 has a guide column, and the lifting bracket 1.2 is equipped with a linear bearing. The guide column and the linear bearing work together to improve the smoothness and stability of the lifting bracket 1.2 during the up and down sliding process.

[0034] Furthermore, a slider module 1.3 is provided on the machine base, which is connected to the sliding bracket 1.1 to improve the smoothness of the rolling roller 6 during the back-and-forth rolling process.

[0035] like Figure 2 , Figure 3 As shown, a further explanation of the implementation method for temperature control of the rolling plate 4 is provided: a temperature detection sensor 1.4 is provided on the rolling assembly 3, and the temperature detection sensor 1.4 is positioned facing the rolling plate 4. The temperature detection sensor 1.4 can be used to detect the stability of the rolling plate 4. When the heating temperature reaches the set value, the temperature detection sensor 1.4 will send a signal to the heating plate 5 to stop heating. At the same time, the rolling assembly 3 rolls the solid battery material on the rolling plate 4 back and forth to ensure that the solid battery material is rolled at a suitable temperature to ensure the rolling effect.

[0036] Furthermore, the rolling assembly 3 is provided with a mounting bracket 1.5, and the temperature detection sensor 1.4 is mounted on the mounting bracket 1.5. The mounting bracket 1.5 is provided with an adjustment groove 1.6 for adjusting the angle of the temperature detection sensor 1.4.

[0038] Furthermore, a positioning sensor 2.2 is inserted on the limiting block 2.1 to detect whether the rolling plate 4 is installed in place, thus preventing the rolling assembly 3 from operating when the rolling plate 4 is not installed in place.

[0039] In addition, the limiting block 2.1 has a locking hole 2.5, and the outer periphery of the rolling plate 4 has a locking limiting groove 2.6 that is opposite to the locking hole 2.5. The locking hole 2.5 can be threadedly connected to the screw, and the screw can be inserted into the locking limiting groove 2.6 and abut against the rolling plate 4 to improve the reliability of the installation of the rolling plate 4.

[0040] Preferably, the rolling plate 4 has an embedded groove 2.7, and the heating plate 5 is disposed in the embedded groove 2.7 to ensure the stability of the installation and increase the contact area with the rolling plate 4 to improve the heat dissipation effect of the heating plate.

After the solid battery material is rolled to an appropriate thickness by the rolling assembly 3, the solid battery material can be cut into a set shape by inserting a cutting block into the cutting groove 2.3.

[0042] Furthermore, the outline of the cutting groove 2.3 gradually expands outward, and the cutting groove 2.3 is embedded with a support part 2.4. By using different cutting blocks to cooperate with the cutting groove 2.3, the solid battery raw materials can be cut into different shapes. The support part 2.4 can also play a supporting role during the rolling process to prevent the film from sinking. When there is only one cutting groove 2.3, the support part 2.4 can be used to fill the other cutting grooves 2.3.

[0043] like Figure 6 , Figure 7 As shown, as a further explanation of the implementation of the cooling channel 3.1, the machine 1 is provided with a cold air circulation structure 3.2. The input end and output end of the cooling channel 3.1 are respectively connected to the cold air circulation structure 3.2, which can quickly cool down the rolling plate 4, causing the film to shrink slightly, making it easier to remove the cut film.

[0044] Specifically, the cold air circulation structure 3.2 includes a cooling unit 3.3 and a storage tank 3.4. The storage tank 3.4 can store refrigerant gas. The gas is input into the cooling channel 3.1 by a vacuum pump / compressor, then into the cooling unit 3.3 for cooling, and finally back into the storage tank 3.4 to realize the recycling of cold air.

[0045] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model.
