[0002] With the rapid development of electronic devices and electric vehicles, the demand for efficient and reliable battery packs has increased significantly. Traditional battery pack manufacturing processes usually rely on manual assembly and machining, which is not only time-consuming and costly, but may also lead to consistency and reliability issues.

[0020] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below 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 creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] The embodiment of the present invention provides an ultra-high viscosity functional fluid printer system for a battery pack, such as Figures 1 to 10 As shown, it includes: a workbench 10, a fluid printing assembly 20, a first moving assembly 30 and a second moving assembly 40, the first moving assembly 30 is used to drive the workbench 10 to move linearly, and the second moving assembly 40 is used to drive the fluid printing assembly 20 to move; The fluid printing assembly 20 comprises a printing tank 21 having a cavity 211 and used for temporarily storing ultra-high viscosity fluid, and a printing cover 22 and a printing nozzle 23 are respectively installed at both ends of the printing tank 21; a vibration assembly 50 is installed on the printing cover 22; The vibration assembly 50 includes a mounting bracket 51 mounted on the print cover 22, an ultrasonic transducer 52 is mounted on the mounting bracket 51, a vibration rod 53 is connected to the ultrasonic transducer 52, and one end of the vibration rod 53 away from the ultrasonic transducer 52 passes through the print cover 22 and is located in the cavity 211. In this embodiment, the ultrasonic transducer 52 is connected to an ultrasonic wave generator commonly used in the art, and the working principle of ultrasonic wave generation is not repeated here.

[0024] It should be noted that the ultra-high viscosity functional fluid printer system for battery packs provided by the present invention specifically includes a workbench 10, a fluid printing assembly 20, a first moving assembly 30 and a second moving assembly 40, wherein the fluid printing assembly 20 includes a printing tank 21, a printing cover 22 and a printing nozzle 23, and a vibration assembly 50 is installed on the printing cover 22. Through the synergistic effect of the first moving assembly 30 and the second moving assembly 40, the fluid printing assembly 20 is driven to move accurately in a three-dimensional space, ensuring high-precision printing operations, and is suitable for complex shapes or high-precision functional coating printing requirements in battery pack production. Through the use of an ultrasonic transducer 52 and a vibration rod 53, the adhesion and flow resistance of the ultra-high viscosity fluid can be effectively reduced, so that the ultra-high viscosity functional fluid can pass through the nozzle smoothly, thereby improving the stability and printing efficiency of the printer. Since the present invention adopts ultrasonic vibration technology, the probability of nozzle clogging is reduced, thereby reducing the maintenance frequency of the equipment and increasing the service life of the equipment. Therefore, the present invention solves the technical problem of poor fluidity of ultra-high viscosity fluids in the 3D printing process in the prior art.

[0025] In this embodiment, the print cover 22 is fastened to the print tank 21 by screws, and the print nozzle 23 is threadedly connected to the print tank 21; in order to facilitate the removal of the print nozzle 23, the outer wall of the print nozzle 23 is provided with a boss 231 of an integrally formed structure; the print nozzle 23 is provided with a first spray hole 232 and a second spray hole 233, the first spray hole 232 is connected to the cavity 211, the first spray hole 232 and the second spray hole 233 are both circular holes, and the inner diameter of the first spray hole 232 is greater than the inner diameter of the second spray hole 233.

[0026] It should be noted that, through the first nozzle 232 and the second nozzle 233 of two different apertures, the flow rate and fineness of the ejected fluid can be adjusted to achieve a higher precision printing effect, especially when processing complex patterns or fine functional layers, the ejection behavior of the fluid can be better controlled. Since the first nozzle 232 is larger, it can quickly supply the fluid to ensure the smooth flow of the fluid, while the second nozzle 233 provides fine control of the fluid ejection and avoids unevenness during the fluid ejection process. Since the print nozzle 23 is threadedly connected to the print tank 21, it is convenient to disassemble and replace the print nozzle 23, which improves the maintainability of the equipment.

[0027] like Figures 5 to 8 As shown, the vibration rod 53 includes a first vibration part 531, a second vibration part 532 and a third vibration part 533 which are sequentially connected along the third direction, and the first vibration part 531 is connected to the ultrasonic transducer 52; The first vibration part 531 and the second vibration part 532 are both cylindrical, and the first vibration part 531 , the second vibration part 532 and the third vibration part 533 are an integrated structure.

[0028] It should be noted that, since the first vibration part 531 is directly connected to the ultrasonic transducer 52, the ultrasonic energy can be efficiently transmitted from the ultrasonic transducer 52 to the inside of the vibration rod 53. Since the vibration rod 53 needs to withstand the high-frequency vibration generated by the ultrasonic transducer 52, the one-piece molding structure can avoid fatigue damage caused by stress concentration at the connection, so that the service life of the vibration rod 53 is longer.

[0029] like Figures 5 to 8 As shown, the width of the first vibrating portion 531 along the second direction is smaller than the width of the second vibrating portion 532 , and the second vibrating portion 532 is provided with a first conical surface 5331 , a second cylindrical surface 5332 and a third conical surface 5333 sequentially connected along the third direction.

[0030] It should be noted that, since the width of the first vibration part 531 along the second direction is smaller than the width of the second vibration part 532, this design helps to evenly distribute the vibration energy on the entire vibration rod 53, ensuring that the high-viscosity fluid in the printing tank 21 can be sufficiently vibrated, thereby improving the fluidity of the fluid. The first conical surface 5331 and the third conical surface 5333 of the vibration rod 53 provide a smoother transition surface, so that the high-viscosity fluid can be more effectively guided during the flow process. The transition setting of the conical surface helps to evenly guide the fluid to the printing nozzle 23 area, improve the fluidity of the fluid at the printing nozzle 23, reduce the risk of clogging of the printing nozzle 23, and ensure stable injection during the printing process. Since the vibration effect of the vibration rod 53 is more uniform and stable, the fluid injection process is smoother, reducing the blockage or unevenness caused by the high viscosity of the fluid. This not only improves the printing speed, but also ensures the accuracy and consistency of each print.

[0031] like Figures 5 to 8 As shown, at least one first exhaust hole 5311 is formed on the outer wall of the first vibrating portion 531 , at least one second exhaust hole 5321 is formed on the outer wall of the second vibrating portion 532 , and a third exhaust hole 5334 is formed on the outer wall of the third vibrating portion 533 ; Among them, a vent pipe 54 is installed at one end of the first vibrating portion 531 close to the ultrasonic transducer 52, and the vent pipe 54 is respectively connected to the first exhaust hole 5311, the second exhaust hole 5321 and the third exhaust hole 5334. In this embodiment, the vent pipe 54 is connected to an external air source, and the external air source can be nitrogen or air. Nitrogen, as an inert gas, is not easy to react with fluids and is suitable for maintaining the stability of airflow during the printing process of high-viscosity fluids. Air, as a common air source, can also provide basic airflow control functions. The flexible choice of the two enhances the adaptability of the system in different printing environments.

[0032] It should be noted that, since the first exhaust hole 5311, the second exhaust hole 5321 and the third exhaust hole 5334 are respectively located at different parts of the vibration rod 53, it is ensured that the vibration rod 53 can achieve more uniform airflow guidance during the ultrasonic vibration process. The airflow enters the cavity 211 of the printing tank 21 through the above-mentioned exhaust hole, which helps to reduce the viscosity of the fluid and improve the fluidity of the fluid, which is particularly important for the printing operation of high-viscosity fluids. By adjusting the airflow in the exhaust hole, the pressure fluctuation during the vibration process can be effectively balanced, and the phenomenon of fluid injection being affected by the uneven pressure generated during the vibration process can be reduced, thereby improving the stability and reliability of the vibration system. Since the gas enters different parts of the vibration rod 53 through the vent pipe 54, the gas guidance is combined with the vibration, which can effectively balance the local heat and pressure generated during the vibration process, and ensure the long-term stability of the vibration system. The vent pipe 54 is connected to an external air source (nitrogen or air), which can facilitate the adjustment of the intensity and direction of the airflow, thereby optimizing the distribution of the airflow in the vibration rod 53. This design allows the operator to flexibly adjust the amount and direction of the airflow according to the printing requirements, thereby improving the operational flexibility and control accuracy of the system.

[0033] like Figures 5 to 8 As shown, a first air passage 534 for connecting the first exhaust hole 5311, the second exhaust hole 5321 and the third exhaust hole 5334 is provided in the vibration rod 53, and the first exhaust hole 5311, the second exhaust hole 5321 and the third exhaust hole 5334 are all arranged in the form of circular holes; in this embodiment, the inner diameter of the first exhaust hole 5311 is 2-3 mm, the inner diameter of the second exhaust hole is 1.5-2.5 mm, and the inner diameter of the third exhaust hole 5334 is 1-2 mm; The angles between the first exhaust hole 5311 and the second exhaust hole 5321 and the first air channel 534 are right angles, and the angle between the third exhaust hole 5334 and the first air channel 534 is an obtuse angle.

[0034] It should be noted that the first air channel 534 is connected to the first exhaust hole 5311, the second exhaust hole 5321 and the third exhaust hole 5334, ensuring that the airflow can flow smoothly in the vibration rod 53 and discharge a suitable amount of air at different parts. The design of the air channel enables the airflow to flow more evenly, which helps to reduce the viscosity of the high-viscosity fluid, thereby improving the fluidity of the fluid and avoiding the blockage of the high-viscosity fluid at the printing nozzle 23. By reasonably designing the angle and inner diameter of the first air channel 534 and the exhaust hole, the airflow can work in coordination with the vibration energy to enhance the working efficiency of the vibration rod 53. In particular, the first exhaust hole 5311 and the second exhaust hole 5321 are respectively arranged at right angles to the first air channel 534, and the linear output of the airflow reduces unnecessary airflow diffusion, thereby reducing the instability of the airflow and ensuring more uniform vibration transmission.

[0035] like Figures 5 to 9 As shown, the outer wall of the first vibrating part 531 is sleeved with a rotatably connected stirring member 55 , the axis of the stirring member 55 is eccentrically arranged with respect to the axis of the first vibrating part 531 , and the stirring member 55 overlaps the second vibrating part 532 .

[0036] Specifically, when the vibration rod 53 starts to vibrate, it drives the stirring member 55 to move in an eccentric manner, which can disturb the fluid in a local area and improve the fluidity of the fluid.

[0037] It should be noted that the stirring member 55 is rotatably connected to the outer wall of the first vibrating portion 531 of the vibrating rod 53, and is eccentrically arranged with respect to the axis of the first vibrating portion 531, so that the stirring member 55 does not rotate symmetrically along the axis during the vibration process, but rotates around an offset point, thereby forming a disturbance effect in the fluid. The eccentric setting enhances the stirring effect, so that high-viscosity fluids can be better mixed and transported. With the high-frequency vibration of the vibrating rod 53, the stirring member 55 drives the surrounding fluid to generate disturbances, enhances the fluidity of the fluid, and avoids blockages caused by ultra-high viscosity. This synergistic effect can ensure that the fluid passes through the printing nozzle 23 smoothly, while improving printing quality and efficiency.

[0038] like Figure 5 , Figure 6 and Fig. 9 As shown, the stirring member 55 includes an eccentric stirring ring 551 sleeved with the first vibrating part 531, and the eccentric stirring ring 551 is provided with a first stirring blade 552 and a second stirring blade 553 at intervals, and the eccentric stirring ring 551, the first stirring blade 552 and the second stirring blade 553 are all integrally formed structures; The first stirring blade 552 is provided with a first helical surface 5521 , the second stirring blade 553 is provided with a second helical surface 5531 , the spiral directions of the first helical surface 5521 and the second helical surface 5531 are opposite, and the weight of the first stirring blade 552 is greater than the weight of the second stirring blade 553 .

[0039] Specifically, when the first vibrating part 531 vibrates through the ultrasonic transducer 52, the stirring member 55 rotates accordingly; the stirring member 55 generates continuous fluid disturbance, which improves the fluidity of the high-viscosity fluid. The relative movement of the first stirring blade 552 and the second stirring blade 553 causes the fluid to be pushed evenly, forming an efficient stirring cycle, avoiding the deposition of the fluid in the printing tank 21, and enhancing the fluidity of the fluid.

[0040] It should be noted that, since the spiral directions of the first helical surface 5521 and the second helical surface 5531 are opposite, during the vibration process, the rotation of the blades and the reverse spiral push of the fluid produce a stronger fluid disturbance effect, reduce the viscosity of the fluid and improve the fluidity of the fluid. Since the weight of the first stirring blade 552 is greater than the weight of the second stirring blade 553, when the eccentric stirring ring 551 rotates, it helps to provide a stronger power to the first stirring blade 552, push more fluid through the stirring area, increase the stirring efficiency, and ensure that the fluid can flow evenly.

[0041] like Figure 5 , Figure 6 and Fig. 9 As shown, the outer wall of the first vibrating portion 531 is provided with a fourth exhaust hole 5312 connected to the vent pipe 54, and the eccentric stirring ring 551 is provided with a second air channel 5511 arranged in an annular shape and connected to the fourth exhaust hole 5312; in this embodiment, the fourth exhaust hole 5312 is connected to the first air channel 534, and the fourth exhaust hole 5312 is located between the second exhaust hole 5321 and the third exhaust hole 5334; At least one first air outlet hole 5522 is formed on the first stirring blade 552 , and at least one second air outlet hole 5532 is formed on the second stirring blade 553 . The first air outlet hole 5522 and the second air outlet hole 5532 are respectively connected to the second air channel 5511 .

[0042] Specifically, the gas enters the first air passage 534 through the ventilation pipe 54, and a part of the gas is discharged from the first exhaust hole 5311, the second exhaust hole 5321, and the third exhaust hole 5334; another part of the gas is discharged from the fourth exhaust hole 5312 and enters the second air passage 5511, and then discharged from the first exhaust hole 5522 and the second exhaust hole 5532.

[0043] It should be noted that the airflow is guided to the first air outlet 5522 of the first stirring blade 552 and the second air outlet 5532 of the second stirring blade 553 through the second air passage 5511, which improves the gas discharge efficiency and enhances the disturbance effect of the stirring member 55, thereby promoting the fluidity of the high-viscosity fluid. In particular, under the action of the eccentric stirring ring 551, the disturbance generated by the first stirring blade 552 and the second stirring blade 553 further optimizes the flow characteristics of the fluid and reduces the unstable printing quality caused by excessive viscosity.

[0044] In summary, in the whole system, the gas is guided by different exhaust holes, which effectively reduces the resistance when the liquid flows, while maintaining the stable operation of the vibration component 50. Through the combination of airflow and ultrasonic vibration, the ultra-high viscosity fluid can pass through the printing nozzle 23 smoothly, avoiding the problem of blocking the printing nozzle 23. Since the airflow can be accurately controlled at multiple positions, the stability of the whole printing process is significantly improved, especially when processing high-viscosity functional fluids, the demand for frequent maintenance is reduced, and the service life of the equipment is improved. Through the design of eccentric setting and spiral surface direction, the first stirring blade 552 and the second stirring blade 553 can continuously promote the fluid during the vibration process, forming a periodic disturbance effect, which helps to break the adhesion of the ultra-high viscosity fluid, thereby improving fluidity. Through the use of the first air outlet 5522, the second air outlet 5532 and the second airway 5511, the guidance of the airflow can enhance the disturbance effect of the first stirring blade 552 and the second stirring blade 553, further reduce the instability of the fluid during the printing process, and ensure the uniformity and accuracy of the print quality.

[0045] like Figures 1 to 3 As shown, the first moving assembly 30 includes a first frame 31, a first driving rod 32 arranged along a first direction is rotatably connected inside the first frame 31, a first moving seat 33 fixedly connected to the workbench 10 is sleeved on the first driving rod 32, and a first moving motor 34 connected to the first driving rod 32 is installed on the first frame 31; At least one first sliding rod 35 arranged parallel to the first driving rod 32 is fixedly installed in the first frame 31 , and a first sliding seat 36 fixedly connected to the workbench 10 is slidably sleeved on the first sliding rod 35 .

[0046] It should be noted that the first driving rod 32 is driven to rotate by the first moving motor 34, which drives the first moving seat 33 to move, and the first slide bar 35 and the first slide seat 36 cooperate to achieve the smooth movement of the workbench 10, which can ensure the movement accuracy of the workbench 10. This design effectively reduces the displacement error caused by vibration or external force interference, and improves the accuracy during the printing process. The sliding cooperation between the first slide seat 36 and the first slide bar 35 ensures the linear movement of the workbench 10 in the first direction, which can not only reduce friction, but also extend the service life of the equipment.

[0047] like Figures 1 to 3 As shown, the second moving assembly 40 includes a second frame 41 connected to the first moving assembly 30, the second frame 41 is slidably connected to a second moving seat 42, and a second driving rod 43 and a second moving motor 44 connected to each other are installed on the second frame 41; the second moving seat 42 is slidably connected to a third frame 45, and a third driving rod 46 and a third moving motor 47 connected to each other are installed on the third frame 45; Among them, the second movable seat 42 is respectively connected with the second driving rod 43 and the third driving rod 46, the second driving rod 43 is arranged along the second direction, and the third driving rod 46 is arranged along the third direction. The first direction, the second direction and the third direction are perpendicular to each other; the printing tank 21 is installed on the third frame 45.

[0048] Specifically, the second frame 41 is fixedly connected to the first frame 31, the third frame 45 is provided with a mounting hole 451, the printing tank 21 passes through the mounting hole 451, the outer wall of the printing tank 21 is provided with a mounting plate 212 of an integrally formed structure, and the mounting plate 212 is fastened to the third frame 45 by screws; the inner wall of the printing tank 21 is provided with a second conical surface 213, and the second conical surface 213 is provided to facilitate the flow of the functional fluid; at least one feed pipe 221 is installed on the printing cover 22, and the feed pipe 221 is provided to facilitate the injection of the functional fluid into the printing tank 21. The second conical surface 213 is provided to enable the functional fluid to flow more smoothly, thereby avoiding the accumulation or stagnation of the fluid in the tank, thereby improving the supply efficiency of the fluid. By providing the feed pipe 221 on the printing cover 22, the functional fluid can be conveniently injected into the printing tank 21, and the feed pipe 221 is connected to a common supply system in the art, which will not be described in detail here.

[0049] It should be noted that since the second drive rod 43 is arranged along the second direction, the third drive rod 46 is arranged along the third direction, and combined with the movement in the first direction, the system can accurately position the printing component in three-dimensional space. By setting the first, second and third directions perpendicular to each other, it is ensured that the printer can move freely and independently in three directions to adapt to more complex printing tasks. This multi-axis coordinated motion mode enables the printer to achieve extremely fine control when performing high-precision functional fluid printing tasks, especially when performing functional coating or printing on surfaces with complex shapes such as battery packs. It has great advantages.

[0050] In summary, the structural design of the present invention enables the printer to improve performance in many aspects when dealing with the printing needs of ultra-high viscosity fluids: through precise three-dimensional motion control, efficient fluid supply system and optimized connection design, the stability, printing quality and work efficiency of the equipment are ensured. These technical effects can greatly improve production efficiency, reduce equipment maintenance costs, and improve printing accuracy in practical applications, and are particularly suitable for functional printing tasks that require high precision and high stability, such as battery packs.

[0051] Working principle: The present invention provides an ultra-high viscosity functional fluid printer system for battery packs, which specifically includes a workbench 10, a fluid printing assembly 20, a first moving assembly 30 and a second moving assembly 40. The fluid printing assembly 20 includes a printing tank 21, a printing cover 22 and a printing nozzle 23, and a vibration assembly 50 is installed on the printing cover 22. Through the synergistic effect of the first moving assembly 30 and the second moving assembly 40, the fluid printing assembly 20 is driven to move accurately in a three-dimensional space, ensuring high-precision printing operations, and is suitable for complex shapes or high-precision functional coating printing requirements in battery pack production. Through the use of an ultrasonic transducer 52 and a vibration rod 53, the adhesion and flow resistance of the ultra-high viscosity fluid can be effectively reduced, so that the ultra-high viscosity functional fluid can pass through the nozzle smoothly, thereby improving the stability and printing efficiency of the printer. Since the present invention adopts ultrasonic vibration technology, the probability of nozzle clogging is reduced, thereby reducing the maintenance frequency of the equipment and increasing the service life of the equipment. Therefore, the present invention solves the technical problem of poor fluidity of ultra-high viscosity fluids in the 3D printing process in the prior art.
