[0005] The utility model provides a printing device, including a printing platform, a drive mechanism and at least two nozzle mechanisms, each of the nozzle mechanisms includes a first drive component and a nozzle component, the first drive component is connected to the drive mechanism, and the nozzle component is connected to the first drive component, each of the first drive components independently drives the nozzle component connected thereto to move, and the drive mechanism drives each of the nozzle mechanisms to move simultaneously.

[0006] In the above-mentioned printing device, 3D printing technology is used to print solid-state batteries, which can simplify the manufacturing process of solid-state batteries and reduce costs. During the printing process, the drive mechanism can drive each nozzle mechanism to move simultaneously relative to the printing platform, and the first drive component of each nozzle mechanism can also drive the nozzle component connected to it to move independently relative to the printing platform, so that each nozzle component can be driven to a desired position by the drive mechanism and each first drive component. In addition, the first drive component of the nozzle mechanism can ensure that there is a certain height difference between the nozzle assembly it drives and the other nozzle assemblies, thereby preventing interference between the nozzle assemblies, and by driving each nozzle assembly to independently spray different printing materials onto the printing platform, a coating with different thickness and pattern is printed on the printing platform. Since the nozzle assemblies do not interfere with each other during the printing process, and each nozzle assembly independently sprays different printing materials, no other components are required between the nozzle assembly and the printing platform. Therefore, different printing materials will not mix with each other during the spraying process, thereby ensuring that the printed coating is free of impurities.

[0007] In one embodiment, the driving mechanism includes a movable part, the first driving assembly is disposed on the movable part, and each of the first driving assemblies independently drives the nozzle assembly connected thereto to move relative to the movable part.

[0017] In one embodiment, each of the nozzle mechanisms further includes a detection component disposed on the first driving component and / or the nozzle component, and the detection component is used to detect the position of the nozzle component.

[0018] With such an arrangement, the detection component can be used to determine whether each nozzle assembly has accurately moved to the printing position and the non-printing position, thereby ensuring the movement accuracy of the nozzle assembly and the printing effect.

In addition, the pneumatic control mechanism has a simple structure, low cost and is easy to control.

[0023] In one embodiment, the nozzle assembly further includes a heating element sleeved outside the material tube.

[0024] With such an arrangement, the printing material stored in the material tube and requiring to be melted for use can be heated by the heating element.

[0025] In one embodiment, the printing device includes three nozzle mechanisms; the nozzle assembly includes a material tube for storing printing raw materials, and the material tube includes a positive electrode material tube, an electrolyte material tube and an edge sealing rubber material tube.

[0043] Traditional solid-state battery manufacturing typically involves separately fabricating the positive and negative electrodes, along with the solid electrolyte layer, and then assembling them into a cell through stacking or winding. This results in a complex and costly manufacturing process. While existing technologies also employ 3D printing to print solid-state batteries, this presents the problem of multiple materials sharing the same discharge channel, leading to impure printed coatings.

[0044] In order to solve the above problems, Figures 1 to 9 As shown, the utility model provides a printing device to simplify the manufacturing process of solid-state batteries and ensure that the printed coating is free of impurities.

[0045] like Figure 1 As shown, specifically, the printing device includes a printing platform 1, a driving mechanism 2 and at least two nozzle mechanisms 3, each nozzle mechanism 3 includes a first driving component 31 and a nozzle assembly 32, the first driving component 31 is connected to the driving mechanism 2, and the nozzle assembly 32 is connected to the first driving component 31, each first driving component 31 independently drives the nozzle assembly 32 connected thereto to move, and the driving mechanism 2 drives each nozzle mechanism 3 to move simultaneously.

[0046] In the printing device provided by the embodiment of the present invention, 3D printing technology is used to print solid-state batteries. There is no need to separately make positive electrode sheets, negative electrode sheets and solid electrolyte layers and then assemble them, which can simplify the manufacturing process of solid-state batteries and reduce costs. During the printing process, the driving mechanism 2 can drive each nozzle mechanism 3 to move relative to the printing platform 1 at the same time, and the first driving component 31 of each nozzle mechanism 3 can also drive the nozzle assembly 32 connected thereto to move independently relative to the printing platform 1, so that each nozzle assembly 32 can be driven to move to the desired position by the driving mechanism 2 and each first driving component 31. In addition, the first driving component 31 of the nozzle mechanism 3 can also drive the nozzle assembly 32 connected thereto to move independently relative to the printing platform 1. The dynamic component 31 can ensure that there is a certain height difference between the nozzle assembly 32 it drives and other nozzle assemblies 32, thereby preventing the nozzle assemblies 32 from interfering with each other, and independently spraying different printing materials to the printing platform 1 through each nozzle assembly 32, so as to print coatings with different thicknesses and patterns on the printing platform 1; since the nozzle assemblies 32 do not interfere with each other during the printing process, no scratches or the like will occur, and each nozzle assembly 32 independently sprays different printing materials, and no other components are required between the nozzle assembly 32 and the printing platform 1, so different printing materials will not mix with each other during the spraying process, so as to ensure that there are no impurities in the printed coating.

[0047] like Figures 1 to 2 As shown, the drive mechanism 2 includes a movable member 21, and a first drive assembly 31 is disposed on the movable member 21. Each first drive assembly 31 independently drives the nozzle assembly 32 connected thereto to move relative to the movable member 21. The movable member 21 drives each nozzle mechanism 3 to move simultaneously relative to the printing platform 1. Each nozzle mechanism 3 is disposed on the movable member 21 via the first drive assembly 31, so that when the movable member 21 moves relative to the printing platform 1, it can drive each nozzle mechanism 3 to move collectively relative to the printing platform 1. The movable member 21 has a simple structure and is easy to assemble. At the same time, each first drive assembly 31 can independently drive the nozzle assembly 32 connected thereto to move relative to the movable member 21, so that each nozzle assembly 32 moves independently relative to the printing platform 1 to achieve switching between the nozzle assemblies 32.

[0048] like Figures 3 and 4As shown, the nozzle assembly 32 is mounted on the first drive assembly 31. The first drive assembly 31 is used to drive the nozzle assembly 32 mounted thereon to reciprocate in a first preset direction, so that the nozzle assembly 32 approaches or moves away from the printing platform 1. When a nozzle assembly 32 needs to be controlled to spray printing material, the first drive assembly 31 connected to the nozzle assembly 32 is controlled to drive the nozzle assembly 32 to move in the first preset direction toward the printing platform 1, so that the nozzle assembly 32 is in the printing position; and the remaining nozzle assemblies 32 are controlled by the remaining first drive assemblies 31 to remain stationary, so that the remaining nozzle assemblies 32 are in the non-printing position, thereby enabling each nozzle assembly 32 to switch between the printing position and the non-printing position. In addition, the movement direction of the nozzle assembly 32 is consistent, thereby ensuring that each nozzle assembly 32 does not interfere with each other when moving independently relative to the movable member 21, facilitating control.

[0049] like Figure 1 As shown, in one embodiment, the printing platform 1 includes a printing plane 11, and the first preset direction is perpendicular to the printing plane 11. When the printing plane 11 is parallel to the XOY plane shown in the figure, the first preset direction can be Figures 1 to 4 The Z-axis direction shown is such that the movement path of each nozzle assembly 32 when switching between the printing position and the non-printing position is the shortest. The printing plane 11 is also used to absorb and fix the foil before printing, and the foil can serve as a current collector for the solid-state battery.

[0050] Of course, in other embodiments, the first preset direction may also be at an acute angle or an obtuse angle with the printing plane 11, and the nozzle assembly 32 may tilt relative to the printing plane 11 to move closer to or away from the printing plane 11; or, each first drive assembly 31 may also drive the nozzle assembly 32 connected thereto to move along other routes such as a preset curve or broken line. As long as it is ensured that each nozzle assembly 32 does not interfere with each other when moving independently relative to the movable part 21, the embodiments of the present invention are not specifically limited here.

[0051] like Figures 3 and 4As shown, in one embodiment, the first drive assembly 31 includes a first cylinder 311, and the nozzle assembly 32 is connected to the first cylinder 311. Each first cylinder 311 drives the nozzle assembly 32 connected thereto to move independently along a first preset direction relative to the movable part 21 by injecting compressed air, ensuring that there is a certain height difference between the nozzle assembly 32 driven by it and other nozzle assemblies 32, thereby preventing the nozzle assemblies 32 from interfering with each other. Moreover, when the air pressure is stable, the movement position of the first cylinder 311 is relatively accurate, thereby ensuring the movement accuracy of the nozzle assembly 32, and the first cylinder 311 has a simple structure, low cost, and is easy to control. Specifically, the first cylinder 311 includes a first fixed portion 3111 and a first movable portion 3112 that can slide back and forth along a first preset direction relative to the first fixed portion 3111, and the nozzle assembly 32 can be detachably connected to the first movable portion 3112 by means of screws, buckles, clamps, etc.

[0052] Furthermore, the printing device also includes a first solenoid valve group connected to the gas source and each first cylinder 311. The first solenoid valve group is used to provide a separate compressed gas to each first cylinder 311. A throttle valve is provided in the first solenoid valve group for adjusting the flow rate of the compressed gas to achieve the purpose of adjusting the movement speed of the nozzle assembly 32 relative to the movable part 21.

[0053] Of course, in other embodiments, the first drive assembly 31 may also include electric guide rails, electric push rods, etc., which can drive each nozzle assembly 32 to move independently relative to the movable part 21 along the first preset direction. The embodiments of the present invention are not specifically limited here.

[0054] like Figures 3 and 4 As shown, in one embodiment, each nozzle mechanism 3 further includes a detection component 33 disposed on the first drive component 31 and / or the nozzle assembly 32. The detection component 33 is used to detect the position of the nozzle assembly 32. Therefore, the detection component 33 can be used to determine whether each nozzle assembly 32 has accurately moved to the printing position and the non-printing position, thereby further ensuring the movement accuracy of the nozzle assembly 32 and the printing effect. Specifically, the detection component 33 can be a travel switch, including a second fixed portion 331 and a second movable portion 332 that can reciprocate along a first preset direction relative to the second fixed portion 331. The second fixed portion 331 is disposed on the first fixed portion 3111 and fixed relative to the first fixed portion 3111. The second movable portion 332 is disposed on the first movable portion 3112 or the nozzle assembly 32 and can move synchronously with the first movable portion 3112 and the nozzle assembly 32 relative to the first fixed portion 3111, so that the second fixed portion 331 and the second movable portion 332 cooperate to detect the position of the nozzle assembly 32 relative to the movable member 21.

[0055] Of course, in other embodiments, the detection component 33 can also be a photoelectric switch or proximity switch provided on the first drive component 31 and / or the nozzle component 32, etc., which can detect the position of the nozzle component 32 relative to the movable part 21. The embodiments of the present invention do not impose specific restrictions here.

[0056] like Figures 3 and 4 As shown, the nozzle assembly 32 includes a material tube 321 for storing printing material. The material tube 321 includes a material outlet 3211 at one end facing the printing platform 1. The printing material is stored in the material tube 321, eliminating the need for connecting the material tube 321 to an external printing material storage device. This reduces the number of connecting pipes and prevents them from interfering with the movement of each nozzle assembly 32 relative to the printing platform 1. The material outlet 3211 facing the printing platform 1 ensures that the material tube 321 accurately positions the printing material on the printing surface 11.

[0057] like Figures 3 and 4 As shown, in one embodiment, an air inlet 3212 is provided at one end of the material tube 321, distal from the discharge port 3211. The printing device further includes a pneumatic control mechanism connected to the air inlet 3212, configured to individually fill the material tube 321 with compressed air through the air inlet 3212. When a particular material tube 321 needs to be controlled to spray printing material, the pneumatic control mechanism connected to that material tube 321 is controlled to pressurize a preset amount of compressed air into that material tube 321 through the air inlet 3212, thereby spraying a predetermined amount of printing material through the discharge port 3211 onto the printing surface 11. The pneumatic control mechanism has a simple structure, low cost, and is easy to control. The preset amount of compressed air injected into the material tube 321 can be adjusted based on the desired amount of printing material, thereby enabling the pneumatic control mechanism to precisely control the discharge amount of each material tube 321.

[0058] Specifically, the pneumatic control mechanism may include an air source processing device, a busbar, an electrical proportional valve, a first solenoid valve group, a second solenoid valve group, a digital pressure gauge, and a vacuum generator. The air source processing device is connected to the air source and is used to remove impurities such as oil and moisture from the compressed air and adjust the total intake air pressure; the busbar is used to split a single compressed gas flow into multiple compressed gas flows; the electrical proportional valve is used to achieve precise air pressure regulation; the first solenoid valve group is used to provide a separate compressed gas to each first cylinder 311; the second solenoid valve group is used to provide a separate compressed gas to each feed pipe 321; and the vacuum generator is used to achieve a negative pressure backflow function. A throttle valve is provided within the vacuum generator to adjust the negative pressure.

[0059] Of course, in other embodiments, the material tube 321 may also be a syringe structure, and the printing material is squeezed out by pushing the plunger in the syringe structure.

[0060] like Figure 2As shown, in one embodiment, the printing device includes three nozzle mechanisms 3. The material pipes 321 of the three nozzle mechanisms 3 are respectively a positive electrode material pipe, an electrolyte material pipe, and an edge-sealing adhesive pipe. The positive electrode material pipe is used to store and spray positive electrode material onto the printing surface 11, the electrolyte material pipe is used to store and spray electrolyte material onto the printing surface 11, and the edge-sealing adhesive pipe is used to store and spray edge-sealing adhesive onto the printing surface 11. This enables integrated printing of the battery positive electrode, electrolyte, and edge-sealing adhesive, meeting the printing requirements of the printing device.

[0061] Of course, in other embodiments, the number of nozzle mechanisms 3 may be two, four, or more. The material pipes 321 of the nozzle mechanism 3 include a positive electrode material pipe, an electrolyte material pipe, and an edge-sealing rubber pipe. The number of nozzle mechanisms 3 and the types of material pipes 321 can be adjusted according to the type of printing material and actual printing requirements, as long as they can meet the printing requirements of the printing device. The embodiments of the present invention are not specifically limited here.

[0062] like Figure 2 As shown, since some of the printing materials for solid-state batteries are solid at room temperature and need to be melted before spraying, the nozzle assembly 32 also includes a heating element 322 that is mounted outside the material tube 321 to heat the printing materials stored in the material tube 321 that need to be melted before use. Specifically, the heating element 322 can be mounted outside the edge sealing rubber tube and is used to heat the edge sealing glue stored in the edge sealing rubber tube to fully melt the edge sealing glue and ensure the edge sealing effect. The heating element 322 can be a heating copper tube, which has good heating effect and low cost.

[0063] like Figures 5 to 7 As shown, in one embodiment, the driving mechanism 2 further includes a second driving component 22, which is used to drive the movable member 21 to reciprocate along a second preset direction. The second preset direction is parallel to the printing plane 11 and can be Figures 5 to 7 The driving mechanism 2 further includes a third driving assembly 23, which is used to drive the movable member 21 to reciprocate along a third preset direction. The third preset direction is parallel to the printing plane 11 and can be Figures 5 to 7 The second driving assembly 22 and the third driving assembly 23 drive the movable member 21 to move to any position on the printing plane 11 on the XOY plane to meet the printing requirements at different positions on the printing plane 11.

[0064] Specifically, the printing device also includes a frame 4, a second drive assembly 22 connected to the frame 4, and the drive mechanism 2 also includes a movable frame 26 connected to the second drive assembly 22. The second drive assembly 22 can be a structure such as an electric guide rail, an electric push rod, a motor pulley assembly, etc. that can drive the movable frame 26 to reciprocate along a second preset direction. A third drive assembly 23 is connected to the movable frame 26, and the movable member 21 is connected to the third drive assembly 23. The third drive assembly 23 can be a structure such as an electric guide rail, an electric push rod, a motor pulley assembly, etc. that can drive the movable member 21 to reciprocate along a third preset direction. Alternatively, the second drive assembly 22 and the third drive assembly 23 can also be configured as a two-axis manipulator, with the movable member 21 connected to the free end of the two-axis manipulator.

[0065] like Figures 8 and 9 As shown, the drive mechanism 2 also includes a fourth drive component 24 connected to the frame 4, and the fourth drive component 24 is used to drive the printing platform 1 to reciprocate along a first preset direction, and the first preset direction is perpendicular to the printing plane 11. Specifically, the fourth drive component 24 can be a structure such as an electric guide rail, an electric push rod, a motor pulley group, etc. that can drive the printing platform 1 to reciprocate along the first preset direction. During the printing process, after the nozzle mechanism 3 sprays and prints each layer of coating, the fourth drive component 24 can drive the printing platform 1 to move a preset distance along the first preset direction toward the side away from the nozzle mechanism 3, so that the nozzle mechanism 3 can continue to spray and print the next layer. The drive mechanism 2 also includes a horizontal component 25 connected to the frame 4 and arranged at the bottom of the printing platform 1. The horizontal component 25 is used to adjust the levelness of the printing platform 1 to ensure the printing effect.

[0066] The printing device provided by the embodiment of the present invention can use the 3D printing slicing algorithm to plan the printing path. The driving mechanism 2 coordinates the movement of each nozzle mechanism 3 and performs the printing action to achieve the effect of fixed-point and quantitative delivery of printing raw materials, thereby achieving the purpose of reducing the loss of solid-state battery materials; it can save the manufacturing cost of the die-cutting mold and reduce the loss in the die-cutting process; the shape of the solid-state battery can be flexibly switched to meet different application scenarios; and because the printing path can be generated at will, while ensuring the accuracy of the driving mechanism 2, each first driving component 31 and the pneumatic control mechanism, it is possible to construct a microscopic three-dimensional structure battery and improve the charging and discharging efficiency of the solid-state battery.
