Description

Technical Field

[0001] The present invention relates to the technical field of solid-state battery manufacturing equipment, and in particular to a solid-state battery film rolling device. Background Art

[0002] Diaphragm rolling is a key process in solid-state battery forming. In the existing technology, solid-state battery raw materials are generally rolled through solid-state battery rolling equipment to ensure that the thickness of the electrode / electrolyte is uniform, dense and defect-free. The rolling effect will directly affect the battery performance and yield.

[0003] For example, a rolling device disclosed in publication number CN206864560U includes a battery fixing device and an extrusion device arranged on one side of the battery fixing device and capable of moving relative to the battery fixing device. The extrusion device includes a rolling roller capable of rotating under the drive of a roller driving device, and a supporting device for supporting and limiting the relative position between the rolling roller and the battery fixing device.

[0004] However, the rolling equipment in the existing technology can only perform one-way reciprocating rolling. The one-way pressure can easily lead to local accumulation or stretching of the raw materials, large fluctuations in the lateral thickness of the membrane, affecting the contact consistency of the battery interface and uneven thickness. In addition, the one-way force will cause the active particles / fibers to be oriented, resulting in anisotropy of ion / electron conduction and reduced battery performance. Summary of the Invention

[0005] In order to solve the technical problems existing in the background technology, the present invention proposes a solid-state battery film rolling device.

[0006] The technical solutions adopted by the present invention to solve the technical problems are as follows:

[0007] A solid-state battery film rolling device includes a mounting base, on which a rolling and forming table and a rolling roller assembly for rolling raw materials are provided;

[0008] The rolling roller assembly includes a rolling support, a forming roller mounted on the rolling support, a lifting module for driving the rolling support to move up and down, and a transverse module for driving the rolling support to move horizontally;

[0009] A forming plate is rotatably mounted on the rolling and forming table, a heating plate for heating the forming plate is embedded in the rolling and forming table, a rotating unit for driving the forming plate to rotate is provided at the bottom of the rolling and forming table, and when the forming roller reciprocates on the forming plate, the rotating unit drives the forming plate to rotate reciprocatingly, and the rotating unit and the transverse movement module alternately drive the forming plate and the forming roller to move.

[0010] Preferably, a heating detection structure is provided on the rolling roller assembly, and the heating detection structure includes a detection bracket and a temperature detection sensor arranged on the detection bracket. The temperature detection sensor is arranged toward the forming plate, and a detection adjustment groove for adjusting the angle of the temperature detection sensor is formed on the detection bracket. Through the above improvements, the temperature detection sensor can accurately detect the temperature of the forming plate to ensure the quality of the rolled film, and the angle of the temperature detection sensor can be adjusted through the detection adjustment groove, which is more convenient for adjusting the position of the temperature detection sensor to ensure the accuracy of temperature measurement.

[0011] Preferably, a heat dissipation channel for rapid cooling is formed in the forming plate, and a cold air delivery structure is provided on the mounting seat, and the output end of the cold air delivery structure is connected to the input end of the heat dissipation channel. Through the above improvements, the cold air delivery structure can deliver cold air to the heat dissipation channel. As the cold air circulates in the heat dissipation channel, it can take away the heat of the forming plate, thereby achieving rapid cooling of the forming plate and causing the formed diaphragm to shrink slightly, thereby making it easier to remove the diaphragm and improving the convenience when cutting the diaphragm.

[0012] Preferably, the rolling roller assembly is provided with a laser projection detection structure, which includes a projection unit and a visual detection head. A forming groove is formed on the forming plate, and the projection unit projects toward the forming plate and constitutes a projection that matches the size of the forming groove. Through the above improvements, after the rolling is completed, the projection unit projects toward the forming plate. If the size of the diaphragm exceeds the projection on the outside, punching is performed to avoid the situation where the diaphragm size is not rolled into place.

[0013] Preferably, a punching structure is provided on the mounting seat, and the punching structure includes a punching head movably arranged above the forming plate, and a punching unit driving the punching head to move up and down, and a forming groove is formed on the forming plate, and the punching unit drives the punching head to descend and be placed into the forming groove to punch the raw material. Through the above improvements, after the rolling is completed, the punching unit will drive the punching head to descend, so that the punching head is inserted into the forming groove, and the membrane is punched into a specified shape.

[0014] Preferably, a plurality of waste blowing holes are arranged at intervals on the outer periphery of the forming groove. Through the above improvements, after punching is completed, the waste blowing holes will release air, thereby blowing up the punched waste and improving the convenience of waste unloading.

[0015] Preferably, an isolation cover structure is provided on the mounting seat, and the isolation cover structure includes a vacuum isolation cover and a lifting unit for driving the vacuum isolation cover to move up and down, and the vacuum isolation cover is connected to a vacuum pipe and an inert gas input pipe. Through the above improvements, before rolling the solid-state battery, the lifting unit will drive the vacuum isolation cover to descend and cover it on the forming plate. The vacuum pipe is used for vacuuming first, and inert gas is injected into the vacuum isolation cover through the inert gas input pipe to make gas atoms adhere to the surface of the solid-state battery raw material, and then the film is rolled, thereby greatly improving the material properties of the solid-state battery raw material.

[0016] Preferably, a weighing trough is formed on the forming plate, and a number of weighing units are arranged at intervals in the weighing trough. Through the above improvements, the weighing units can be used to accurately calculate the mass of the diaphragm before and after forming, which not only ensures the forming quality but also saves raw materials to reduce manufacturing costs.

[0017] Preferably, a gap adjustment structure is provided on the mounting seat, and the gap adjustment structure includes a lighting unit, a projection receiving plate, and a gap measuring lens. The lighting unit irradiates toward the forming roller so that the projection of the forming roller is mapped on the projection receiving plate, and the gap measuring lens measures the projected gap between the forming roller and the rolling bracket. Through the above improvements, the gap measuring lens can be used to accurately detect the gap between the forming roller and the rolling bracket, so as to improve the adjustment accuracy of the forming roller, thereby improving the rolling quality of the diaphragm.

[0018] Preferably, a supporting guide structure is provided on the rolling and forming table, and the supporting guide structure includes a supporting guide block and a pushing unit for driving the supporting guide block to move toward the forming plate. A supporting groove for the supporting guide block to be placed is formed on the forming plate, and the forming plate rotates along the supporting guide block. Through the above improvements, the stability of the forming block during the rotation process is improved.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] A rolling and forming table and a rolling roller assembly for rolling the raw materials are arranged on the mounting seat. The rolling roller assembly includes a rolling bracket, a forming roller rotatably mounted on the rolling bracket, a lifting module for driving the rolling bracket to move up and down, and a transverse module for driving the rolling bracket to move horizontally. A forming plate is rotatably mounted on the rolling and forming table. A rotating unit for driving the forming plate to rotate is provided at the bottom of the rolling and forming table. When the forming roller reciprocates on the forming plate, the rotating unit drives the forming plate to rotate reciprocatingly. By combining the synchronous reciprocating rotation of the forming plate with the reciprocating rolling of the rolling roller, the force on each area of ​​the raw material is more balanced, and the uneven thickness or stress concentration caused by unidirectional rolling is avoided simultaneously, thereby improving the density of the membrane. The bidirectional movement disrupts the directional arrangement of the particles / fibers, reduces anisotropy, optimizes the uniformity of ion transmission, and shortens the rolling path by rotating the forming plate, reduces the number of repeated rolling times, and improves production efficiency.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] It should be understood that although terms such as upper, middle, lower, top, end, etc. appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for ease of understanding, and are not used to define any direction or order limitation.

[0033] like Figure 1-9 As shown, a solid-state battery film rolling device includes a mounting base 1, on which a rolling and forming table 2 and a rolling roller assembly 3 for rolling raw materials are provided.

[0034] Specifically, the rolling roller assembly 3 includes a rolling bracket 1.1, a forming roller 1.2 rotated on the rolling bracket 1.1, a lifting module 1.3 driving the rolling bracket 1.1 to move up and down, and a transverse module 1.4 driving the rolling bracket 1.1 to move horizontally.

[0035] Furthermore, a forming plate 1.5 is rotated on the rolling and forming table 2, and a rotating unit 1.6 for driving the forming plate 1.5 to rotate is provided at the bottom of the rolling and forming table 2, and when the forming roller 1.2 rolls back and forth on the forming plate 1.5, the rotating unit 1.6 drives the forming plate 1.5 to rotate back and forth, and the rotating unit 1.6 and the transverse module 1.4 alternately drive the forming plate 1.5 and the forming roller 1.2 to move.

[0036] By combining the synchronous reciprocating rotation of the forming plate 1.5 with the reciprocating rolling of the rolling roller, the force on each area of ​​the raw material is more balanced, and the uneven thickness or stress concentration of the membrane caused by one-way rolling is avoided, thereby improving the density of the membrane. In addition, the bidirectional movement disrupts the directional arrangement of particles / fibers, reduces anisotropy, and optimizes the uniformity of ion transmission. The rotating forming plate 1.5 can also shorten the rolling path, reduce the number of repeated rolling, and improve production efficiency.

[0037] For further explanation of the rolling process, first, the forming roller 1.2 rolls in one direction once (from left to right) → the base rotates 15°-30° → the forming roller 1.2 rolls in the opposite direction once (from right to left) → the base rotates in the opposite direction 15°-30° (completes 1 reciprocating cycle). The number can be set according to the thickness of the membrane. If the thickness of the ultra-thin film is set to 1-2μm, the number of rolling times is set to 50-100 times, so that the solid-state battery raw materials are rolled into a uniform membrane.

[0038] Preferably, during the rolling process, the pressure gradient decreases to avoid damage to the membrane.

[0039] like Figure 1 、 Figure 6 As shown, as a further explanation of the temperature control of the forming plate 1.5, a heating detection structure 2.1 is provided on the rolling roller assembly 3. During the rolling and forming process, the solid-state battery raw material is first spread flat on the forming plate 1.5, and the heating plate 1.7 heats up and conducts the temperature to the forming plate 1.5. The heating detection structure 2.1 stops heating after detecting the set temperature, ensuring that the solid-state battery raw material is rolled at a set temperature to ensure the rolling and forming effect.

[0040] Specifically, the heating detection structure 2.1 includes a detection bracket 2.2, and a temperature detection sensor 2.3 arranged on the detection bracket 2.2. The temperature detection sensor 2.3 is arranged toward the forming plate 1.5, and a detection adjustment groove 2.4 for adjusting the angle of the temperature detection sensor 2.3 is formed on the detection bracket 2.2. The temperature detection sensor 2.3 can accurately detect the temperature of the forming plate 1.5 to ensure the quality of the rolled film, and the angle of the temperature detection sensor 2.3 can be adjusted through the detection adjustment groove 2.4, which makes it easier to adjust the position of the temperature detection sensor 2.3 to ensure the accuracy of temperature measurement.

[0041] like Figures 1 to 3 As shown, a further explanation of the implementation method of the rolling roller assembly 3 in this embodiment is provided, the rolling roller assembly 3 includes a rolling bracket 1.1, a forming roller 1.2 rotated on the rolling bracket 1.1, a lifting module 1.3 for driving the rolling bracket 1.1 to move up and down, and a transverse module 1.4 for driving the rolling bracket 1.1 to move horizontally.

[0042] Furthermore, the rolling roller assembly 3 also includes a sliding bracket 1.8, and the rolling bracket 1.1 can be slidably set on the sliding bracket 1.8. The action end of the transverse module 1.4 is connected to the sliding bracket 1.8, and the action end of the lifting module 1.3 is connected to the rolling bracket 1.1, thereby realizing the driving of the forming roller 1.2.

[0043] Preferably, a slider module 1.9 is provided on the mounting base 1, and the sliding bracket 1.8 is connected to the slider module 1.9, thereby improving the smoothness of the sliding bracket 1.8 during movement.

[0044] like Figure 3 、 Figure 6 、 Figure 7 As shown, as a further explanation of the embodiment of the rotation of the forming plate 1.5, the rotating unit 1.6 is a servo motor, and the action end of the rotating unit 1.6 is connected to the forming plate 1.5, thereby driving the forming plate 1.5 to rotate accurately.

[0045] Furthermore, a supporting guide structure 9.1 is provided on the rolling and forming table 2, and the supporting guide structure 9.1 includes a supporting guide block 9.2 and a pushing unit 9.3 that drives the supporting guide block 9.2 to move toward the forming plate 1.5. A supporting groove 9.4 is formed on the forming plate 1.5 for the supporting guide block 9.2 to be placed, and the forming plate 1.5 rotates along the supporting guide block 9.2.

[0046] Among them, the forming plate 1.5 is arranged in a circular shape, and the supporting guide block 9.2 has a guide part 9.5 and a supporting part 9.6. When rolling, the supporting part 9.6 will be inserted into the supporting groove 9.4, so as to avoid deformation of the forming plate 1.5 during the rolling process, and a guide ball 9.7 is embedded on the inner wall of the guide part 9.5, and the guide ball 9.7 is attached to the outer periphery of the forming plate 1.5 to improve the smoothness of the forming plate 1.5 during the rotation process.

[0047] In some other embodiments, a gap adjustment structure 8.1 is provided on the mounting base 1, and the gap adjustment structure 8.1 includes a lighting unit 8.2, a projection receiving plate 8.3, and a gap measuring lens 8.4.

[0048] Before rolling, the position of the forming roller 1.2 needs to be adjusted, and the lighting unit 8.2 is used to illuminate the forming roller 1.2 so that the projection of the forming roller 1.2 and the rolling bracket 1.1 is illuminated on the projection receiving plate 8.3. The gap measurement lens 8.4 can be used to accurately detect the gap between the forming roller 1.2 and the rolling bracket 1.1 to improve the adjustment accuracy of the forming roller 1.2, thereby improving the rolling quality of the membrane. Example

[0049] like Figure 1 As shown, the difference between this embodiment and the first embodiment is that a heat dissipation channel 3.1 for rapid cooling is formed in the forming plate 1.5, and a cold air delivery structure 3.2 is provided on the mounting base 1, and the output end of the cold air delivery structure 3.2 is connected to the input end of the heat dissipation channel 3.1. The cold air delivery structure 3.2 can deliver cold air to the heat dissipation channel 3.1. As the cold air circulates in the heat dissipation channel 3.1, it can take away the heat of the forming plate 1.5, thereby achieving rapid cooling of the forming plate 1.5 and causing the formed diaphragm to shrink slightly, making it easier to remove, thereby improving the convenience of diaphragm cutting.

[0050] In addition, a plurality of waste blowing holes 5.5 are arranged at intervals on the periphery of the forming groove 5.4. After punching is completed, the waste blowing holes 5.5 will vent air, thereby blowing up the punched waste and improving the convenience of waste unloading.

[0051] Preferably, the diameter of the heat dissipation channel 3.1 is 10 mm, and the heat dissipation channel 3.1 is spirally arranged at intervals of 2 mm in the molding plate 1.5 to evenly cool the entire molding plate 1.5. Example

[0052] like Figures 1 to 4 As shown, the difference between this embodiment and embodiment 1 is that a punching structure 5.1 is provided on the mounting seat 1, and the punching structure 5.1 includes a punching head 5.2 and a punching unit 5.3 that drives the punching head 5.2 to move up and down, and the punching unit 5.3 and the punching head 5.2 are arranged on the first mounting bracket 5.6, and the first mounting bracket 5.6 is driven to move by a direct module, and a forming groove 5.4 is formed on the forming plate 1.5, and the punching unit 5.3 drives the punching head 5.2 to descend and be placed in the forming groove 5.4 to punch the raw material. After the rolling is completed, the punching unit 5.3 will drive the punching head 5.2 to descend, so that the punching head 5.2 is inserted into the forming groove 5.4, and the diaphragm is punched into a specified shape.

[0053] Furthermore, a laser projection detection structure 4.1 is provided on the rolling roller assembly 3. The laser projection detection structure 4.1 includes a projection unit 4.2 and a visual detection head 4.3. A forming groove 5.4 is formed on the forming plate 1.5. The projection unit 4.2 projects toward the forming plate 1.5 and constitutes a projection that matches the size of the forming groove 5.4.

[0054] After the rolling is completed, the projection unit 4.2 projects toward the forming plate 1.5. If the outer size of the membrane exceeds the projection, punching is performed to avoid the situation where the membrane size is not rolled into place.

[0055] Preferably, a plurality of forming grooves 5.4 are formed on the forming plate 1.5. The forming grooves 5.4 are arranged at intervals on the forming plate 1.5 and continuously expand along the outer contour of the forming plate 1.5. Different sizes of punching heads 5.2 can be matched with the forming grooves 5.4 to punch and form membranes of different sizes.

[0056] When it is necessary to replace a different forming groove 5.4, a filling block can be embedded in another forming groove 5.4 to avoid the diaphragm from being sunken during the rolling process.

[0057] Preferably, the lighting unit 8.2 is arranged on the first mounting bracket 5.6, and the lighting distance is adjusted by moving the first mounting bracket 5.6, thereby improving the detection accuracy. Example

[0058] like Figure 1 、 Figure 2 、 Figure 5 As shown, the difference between this embodiment and the first embodiment is that an isolation cover structure 6.1 is provided on the mounting base 1, and the isolation cover structure 6.1 includes a vacuum isolation cover 6.2 and a lifting unit 6.3 for driving the vacuum isolation cover 6.2 to move up and down. The vacuum isolation cover 6.2 and the lifting unit 6.3 are arranged on the second mounting bracket 6.6, and the second mounting bracket 6.6 is driven to move by the linear module, and the vacuum isolation cover 6.2 is connected to a vacuum pipe 6.4 and an inert gas input pipe 6.5.

[0059] Before rolling the solid-state battery, the lifting unit 6.3 will drive the vacuum isolation cover 6.2 to descend and cover the forming plate 1.5. The vacuum tube 6.4 will be used for vacuuming first, and inert gas will be injected into the vacuum isolation cover 6.2 through the inert gas input pipe 6.5. Gas atoms will adhere to the surface of the solid-state battery raw material, and then the film will be rolled, thereby greatly improving the material performance of the solid-state battery raw material.

[0060] Preferably, a sealing ring 6.7 is provided on the forming plate 1.5. When the vacuum isolation cover 6.2 descends, it abuts against the sealing ring 6.7, thereby improving the vacuuming effect. Example

[0061] like Figure 9As shown, the difference between this embodiment and the first embodiment is that a weighing tank 7.1 is formed on the forming plate 1.5, and a plurality of weighing units 7.2 are arranged at intervals in the weighing tank 7.1. The upper cover of the weighing tank 7.1 is provided with a protective plate. The weighing units 7.2 can accurately calculate the mass of the diaphragm before and after forming, which not only ensures the forming quality but also saves raw materials to reduce manufacturing costs.

[0062] Before the rolling roller assembly 3 is rolled, the raw materials of the solid-state battery on the forming plate 1.5 will be weighed to ensure that a fixed amount of solid-state battery raw materials are rolled, thereby avoiding waste and reducing manufacturing costs.

[0063] Furthermore, after the rolling is completed and the excess scraps are removed, the rolled membrane is weighed again to keep the membrane at a specified weight. This not only improves the uniformity of the membrane rolling, but also ensures the quality of the solid-state battery.

[0064] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
