Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, and in particular to a solid-state battery composite electrolyte casting coating equipment. Background Technology

[0002] Solid-state batteries, with their advantages of high energy density, high safety, and long cycle life, are considered the core development direction of next-generation energy storage technology. Composite solid-state electrolytes, as a key material in solid-state batteries, combine the high ionic conductivity of inorganic electrolytes (oxides / sulfides) with the flexibility of polymer electrolytes, representing a mainstream technological approach to resolving the trade-off between ionic conductivity and mechanical strength in single-component electrolytes. The fabrication precision, uniformity, and structural integrity of composite electrolyte membranes directly determine the interfacial impedance, cycle stability, and safety performance of solid-state batteries; therefore, mass production equipment for composite electrolyte membranes has become a core bottleneck restricting the industrialization of solid-state batteries.

[0003] A search revealed a polycarbonate film casting coating device disclosed in patent CN119328968B. The patent states that "limiting the roll before winding prevents movement during winding, improving the quality of the roll. A blower blows air at high speed through a guide frame and a flat spray tube. The cooling roller rotates, driving a threaded rod via a transmission assembly. This rotation, in turn, drives a threaded plate and a rack rod to move horizontally back and forth. The rack rod's horizontal movement then drives a gear and a flat spray tube to oscillate back and forth. This oscillation sweeps the air across the polycarbonate film on the cooling roller surface. Because the spray tube's outlet is flat, the air acts like a scraper, squeezing out air bubbles between the polycarbonate film and the cooling roller. The reciprocating air helps the polycarbonate film adhere better to the cooling roller surface, reducing the likelihood of bulging." However, this device still has the following problems:

[0004] 1. This device only relies on a blower to make the membrane adhere more closely to the surface of the cooling roller and to cool and shape it in conjunction with the cooling roller, but it does not describe the cooling method of the cooling roller. If natural cooling is used to achieve shaping, it is easy to cause insufficient cooling uniformity, and it is impossible to achieve rapid and uniform shaping of the coated composite electrolyte membrane.

[0005] 2. The device does not have a dedicated substrate cleaning structure, so it cannot remove dust, particles and other impurities from the substrate surface in advance. These impurities will embed into the membrane layer during the coating process, causing defects such as pinholes and pits in the electrolyte membrane, which seriously affects the membrane density and performance.

[0006] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Summary of the Invention

[0007] The purpose of this invention is to provide a solid-state battery composite electrolyte casting coating equipment to solve the problems mentioned in the background art, such as the lack of a dedicated cooling circulation structure for the cooling roller, poor cooling uniformity and shaping efficiency, and the absence of a substrate cleaning structure, which makes it easy for substrate impurities to cause pinholes and pits in the electrolyte film, making it difficult to guarantee the quality and precision of the film forming.

[0014] Preferably, the telescopic cleaning mechanism includes a positioning seat fixedly installed on the top surface of the first support frame, a fixing rod fixedly installed on the top and bottom surfaces of the positioning seat, a movable plate slidably sleeved on the outer ring of the fixing rod, a telescopic spring sleeved on the outer ring of the fixing rod between the movable plate and the positioning seat, and a cleaning scraper fixedly installed on the front side of the movable plate.

[0016] Preferably, the fixed rod and the telescopic spring are evenly distributed between the positioning seat and the movable plate, the movable plate is telescopically connected to the positioning seat through the telescopic spring, and the diverting plate is evenly distributed inside the dust collection seat.

[0017] Preferably, the limiting adjustment mechanism includes an adjusting seat threaded onto the outer rings of both ends of the positioning rod, a connecting seat rotatably mounted on the outer ring of the adjusting seat, a support rod fixedly connected to the connecting seat, and a first limiting ring fixedly connected to the end of the support rod away from the connecting seat, the first limiting ring being movably sleeved with the cooling roller.

[0018] Preferably, the limiting adjustment mechanism further includes a second limiting ring fixedly installed on the front side of the first limiting ring, the second limiting ring being movably sleeved with the second auxiliary roller, and a third limiting ring fixedly installed on the rear side of the first limiting ring, the third limiting ring being movably sleeved with the third auxiliary roller.

[0019] Preferably, the cooling circulation mechanism includes diversion grooves opened at equal angles inside the cooling roller, and rotating rings are rotatably installed on the inner rings at both ends of the cooling roller.

[0020] Preferably, the cooling circulation mechanism further includes an inlet pipe fixedly installed on the rotating ring at the right end, the inlet end of the inlet pipe being fixedly connected to a first manifold, the bottom end of the first manifold being connected to a water pump, the water pump being fixedly connected to a support base, and an outlet pipe installed on the rotating ring at the left end, the outlet end of the outlet pipe being connected to a second manifold.

[0021] Preferably, the casting coating mechanism includes a storage tank fixedly installed on the top of the positioning frame. A top cover is bolted to the top of the storage tank. A drive motor is fixedly installed in the middle of the top surface of the top cover. A transmission rod is connected to the shaft end of the drive motor. The top of the transmission rod is rotatably connected to the top cover. A side rod is fixedly installed at an equal angle in the middle of the transmission rod. An anti-stick scraper is fixedly connected to the end of the side rod away from the transmission rod. The outer side of the anti-stick scraper is tightly fitted to the inner wall of the storage tank.

[0022] Preferably, the casting coating mechanism further includes a solenoid valve connected to the bottom of the storage tank, and a coating seat is fixedly connected to the bottom of the solenoid valve.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. By setting up a telescopic cleaning mechanism, the telescopic spring elastically pushes the movable plate to keep the cleaning scraper always in contact with the substrate surface. Combined with the negative pressure dust suction structure formed by the dust collection seat, the diverter plate and the external dust collection equipment, the dust, particles and fine impurities on the substrate surface can be scraped and adsorbed simultaneously before the coating operation. This effectively solves the problem that the traditional coating equipment has inadequate substrate pretreatment and the impurity residue can easily cause pinholes and pits in the electrolyte film. It greatly improves the cleanliness of the substrate surface, ensures the flatness and film density of the subsequent composite electrolyte casting coating, and improves the forming quality of the solid electrolyte film.

[0025] 2. By setting up a limit adjustment mechanism, relying on the linkage adjustment structure of the adjustment seat, connecting seat and support rod, the installation positions of the first limit ring, the second limit ring and the third limit ring can be flexibly and finely adjusted according to the width of the substrate. This allows the three sets of limit rings to form precise limit guidance corresponding to the cooling roller, the second auxiliary roller and the third auxiliary roller, respectively. This effectively corrects the offset and deviation problems in the substrate conveying process, and avoids wrinkles, stretching deformation and edge misalignment of the substrate during coating, conveying and cooling and shaping. It ensures the stability and consistency of substrate conveying and improves the stability of continuous coating operation of the equipment.

[0026] 3. By setting up a cooling circulation mechanism, a water pump drives the coolant through the first manifold and the inlet pipe into the distribution groove inside the cooling roller. Combined with the rotating sealing structure of the rotating rings at both ends, the coolant is circulated. This can uniformly and continuously cool and shape the coated electrolyte membrane, quickly remove the heat generated by the substrate during the coating process, effectively solve the problem of slow electrolyte membrane shaping caused by the lack of a cooling structure in traditional equipment, accelerate the curing and shaping speed of the membrane layer, and improve the structural stability of the composite electrolyte membrane.

[0027] 4. By setting up a casting coating mechanism, the drive motor drives the transmission rod to rotate, so that the stirring blades continuously and evenly stir the composite electrolyte slurry inside the storage tank. At the same time, the anti-stick scraper at the end of the side rod scrapes off the slurry adhering to the inner wall of the storage tank in real time, avoiding slurry sedimentation and clumping, ensuring the overall composition of the slurry is uniform and the flowability is stable. Then, the solenoid valve precisely controls the material and works with the coating seat to complete the uniform casting coating, effectively improving the shortcomings of uneven slurry mixing and unstable coating output of traditional equipment, ensuring the uniform thickness of the electrolyte film, and meeting the production requirements of composite electrolyte films for solid-state batteries.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-8 This invention provides a technical solution: a solid-state battery composite electrolyte casting coating device, including a support base 1.

[0039] A first support frame 2 and a second support frame 14 are fixedly installed on the front side of the support base 1. A first connecting rod 3 is fixedly installed on the top of the first support frame 2. A first auxiliary roller 4 is rotatably sleeved on the outer ring of the first connecting rod 3. A telescopic cleaning mechanism is fixedly installed on the top surface of the first support frame 2.

[0040] A second connecting rod 15 is fixedly installed at the top of the second support frame 14. A second auxiliary roller 16 is rotatably sleeved on the outer ring of the second connecting rod 15. A positioning rod 17 is installed at the top of the support base 1. A cooling roller 18 is rotatably sleeved on the outer ring of the positioning rod 17. A third support frame 19 is fixedly installed at the rear side of the support base 1. A third connecting rod 20 is fixedly installed at the top of the third support frame 19. A third auxiliary roller 21 is rotatably sleeved on the outer ring of the third connecting rod 20.

[0041] Limit adjustment mechanisms are provided at both ends of the positioning rod 17;

[0042] The cooling roller 18 is equipped with a cooling circulation mechanism inside;

[0043] Positioning frames 35 are fixedly installed on the top surfaces of the second support frame 14 and the third support frame 19, and a casting coating mechanism is installed on the top of the positioning frame 35.

[0044] Furthermore, the telescopic cleaning mechanism includes a positioning seat 5 fixedly installed on the top surface of the first support frame 2. A fixing rod 6 is fixedly installed on the top and bottom surfaces of the positioning seat 5. A movable plate 7 is slidably sleeved on the outer ring of the fixing rod 6. A telescopic spring 8 is sleeved on the outer ring of the fixing rod 6 between the movable plate 7 and the positioning seat 5. A cleaning scraper 9 is fixedly installed on the front side of the movable plate 7. The positioning seat 5 provides a stable installation base for the overall cleaning structure. The fixed rod 6 is used to achieve directional sliding limit of the movable plate 7. The elastic pushing force of the telescopic spring 8 makes the cleaning scraper 9 at the front end of the movable plate 7 always elastically fit against the surface of the substrate, stably scraping away the particulate impurities attached to the surface of the substrate, avoiding rigid scraping damage to the substrate, and ensuring the stability of the pretreatment cleaning.

[0045] Furthermore, the telescopic cleaning mechanism also includes a connecting plate 10 symmetrically installed on the top surface of the positioning seat 5. A dust collection seat 11 is fixedly connected to the bottom end of the connecting plate 10. A diverter plate 12 is installed inside the dust collection seat 11, and a connecting pipe 13 is installed on the top of the dust collection seat 11. The dust collection seat 11 is fixedly supported by the connecting plate 10, so that the dust collection structure and the cleaning scraper 9 form an integrated cleaning structure. With the connection pipe 13 connected to the external negative pressure dust collection equipment, and combined with the diverter plate 12 inside the dust collection seat 11, the negative pressure airflow is evenly distributed, which can quickly absorb and collect the dust and debris scraped off by the scraper, realize the simultaneous operation of scraping and dust collection, remove impurities on the substrate surface, and avoid film defects caused by impurity residue.

[0046] Furthermore, the fixed rods 6 and telescopic springs 8 are evenly distributed between the positioning seat 5 and the movable plate 7. The movable plate 7 is telescopically connected to the positioning seat 5 through the telescopic springs 8. The diverter plates 12 are evenly distributed inside the dust collection seat 11. The evenly distributed fixed rods 6 and telescopic springs 8 can form a uniform and balanced elastic support force on the movable plate 7, ensuring that the cleaning scraper 9 is evenly stressed and adheres more smoothly to the substrate, avoiding cleaning dead corners or scratches caused by uneven local pressure. The evenly distributed diverter plates 12 can balance the negative pressure airflow inside the dust collection seat 11, making the suction force in the dust collection area uniform and improving the impurity cleaning effect.

[0047] Furthermore, the limiting adjustment mechanism includes an adjusting seat 22 threaded onto the outer rings at both ends of the positioning rod 17. A connecting seat 23 is rotatably mounted on the outer ring of the adjusting seat 22. A support rod 24 is fixedly connected to the connecting seat 23. A first limiting ring 25 is fixedly connected to the end of the support rod 24 away from the connecting seat 23. The first limiting ring 25 is movably sleeved with the cooling roller 18. By threading the adjusting seat 22 onto the positioning rod 17, the installation position can be flexibly adjusted according to the actual width of the substrate. The connecting seat 23 and the support rod 24 stably support the first limiting ring 25, thereby limiting and constraining the substrate conveyed at the cooling roller 18 on both sides, effectively preventing the substrate from shifting laterally or deviating during the cooling and shaping stage, and ensuring the stability of the substrate conveying trajectory.

[0048] Furthermore, the limiting adjustment mechanism also includes a second limiting ring 26 fixedly installed on the front side of the first limiting ring 25. The second limiting ring 26 is movably sleeved with the second auxiliary roller 16. A third limiting ring 27 is fixedly installed on the rear side of the first limiting ring 25. The third limiting ring 27 is movably sleeved with the third auxiliary roller 21. The second limiting ring 26, the first limiting ring 25, and the third limiting ring 27 respectively correspond to the second auxiliary roller 16, the cooling roller 18, and the third auxiliary roller 21 to form a continuous limiting and guiding structure, realizing the limiting of the entire conveying path of substrate feeding, cooling, and discharging, avoiding wrinkles, stretching, misalignment and deformation during multi-segment conveying of the substrate, and improving the stability of continuous coating operations.

[0049] Furthermore, the cooling circulation mechanism includes diversion grooves 28 that are equally angled inside the cooling roller 18. Rotating rings 29 are rotatably installed on the inner rings at both ends of the cooling roller 18. The diversion grooves 28 that are equally angled inside the cooling roller 18 can increase the flow area and heat exchange range of the coolant, ensuring uniform temperature around the roller body. The rotating rings 29 at both ends can keep the pipeline sealed and connected when the cooling roller 18 is rotating, preventing coolant leakage and achieving continuous and stable heat exchange during the dynamic rotation of the roller body, providing a structural basis for uniform cooling and shaping of the film.

[0050] Furthermore, the cooling circulation mechanism also includes an inlet pipe 30 fixedly installed on the right rotating ring 29. The inlet end of the inlet pipe 30 is fixedly connected to a first manifold 31, and the bottom end of the first manifold 31 is connected to a water pump 32. The water pump 32 is fixedly connected to the support base 1. An outlet pipe 33 is installed on the left rotating ring 29, and the outlet end of the outlet pipe 33 is connected to a second manifold 34. The water pump 32 provides circulation power, and the externally stored coolant is introduced into the cooling roller 18 through the first manifold 31 and the inlet pipe 30. Then, the coolant flows back through the outlet pipe 33 and the second manifold 34 to form a closed-loop circulation system. This can quickly and evenly remove the heat of the coated film, solve the problems of uneven shaping and low cooling efficiency of traditional air cooling, and achieve rapid and uniform shaping of the electrolyte membrane.

[0051] Furthermore, the casting coating mechanism includes a storage tank 36 fixedly installed on the top of the positioning frame 35. A top cover 37 is bolted to the top of the storage tank 36. A drive motor 38 is fixedly installed in the middle of the top surface of the top cover 37. A transmission rod 39 is connected to the shaft end of the drive motor 38. The top of the transmission rod 39 is rotatably connected to the top cover 37. A side rod 40 is fixedly installed at an equal angle in the middle of the transmission rod 39. An anti-stick scraper 41 is fixedly connected to the end of the side rod 40 away from the transmission rod 39. The outer side of the anti-stick scraper 41 is connected to... The inner wall of the storage tank 36 is tightly fitted, and the bottom end of the transmission rod 39 is equipped with stirring blades 42 at equal angles. The drive motor 38 drives the transmission rod 39 to rotate. The bottom stirring blades 42 can stir the composite electrolyte slurry inside the storage tank 36 in all directions to prevent the slurry from settling, agglomerating and separating. At the same time, the side rod 40 drives the anti-stick scraper 41 to scrape off the slurry adhering to the tank wall in real time, effectively avoiding the slurry from sticking to the wall, drying, deteriorating and wasting. This continuously ensures that the slurry composition is uniform and the fluidity is consistent, providing stable slurry conditions for high-precision casting coating.

[0052] Furthermore, the casting coating mechanism also includes a solenoid valve 43 connected to the bottom of the storage tank 36. The bottom of the solenoid valve 43 is fixedly connected to the coating seat 44. The solenoid valve 43 precisely controls the flow rate and on / off state of the slurry in the storage tank 36. Together with the coating seat 44, it achieves uniform, stable and quantitative casting coating of the slurry, avoiding problems such as uneven film thickness and coating interruption caused by fluctuating discharge, and effectively improving the coating accuracy of the composite electrolyte membrane.

[0053] Working principle: When this equipment is working, the whole equipment is supported and fixed by the support base 1. The working substrate passes through the top of the first support frame 2 in sequence and forms a continuous conveying path through the first auxiliary roller 4, the second auxiliary roller 16, the cooling roller 18 and the third auxiliary roller 21. During the substrate conveying process, the telescopic cleaning mechanism at the top of the first support frame 2 completes the substrate pretreatment first. The positioning base 5 provides the installation benchmark, the fixed rod 6 slides and guides the movable plate 7, and the elastic action of the telescopic spring 8 makes the cleaning scraper 9 on the front side of the movable plate 7 always elastically fit the substrate surface, and uniformly scrapes off the particulate impurities on the substrate surface. At the same time, the dust collection seat 11 fixed by the connecting plate 10 on the top surface of the positioning base 5 is connected to the negative pressure air source through the top connecting pipe 13, and the negative pressure airflow is evenly distributed by the diverting plates 12 arranged at equal intervals inside the dust collection seat 11, which quickly adsorbs and collects the scraped dust and debris.

[0054] The limiting adjustment mechanism at both ends of the positioning rod 17 is position-adjustable through the threaded adjustment seat 22. The first limiting ring 25, supported by the connecting seat 23 and the support rod 24, is movably sleeved on the outside of the cooling roller 18. At the same time, the second limiting ring 26 and the third limiting ring 27 are respectively sleeved on the outside of the second auxiliary roller 16 and the third auxiliary roller 21, forming a limiting and guiding structure covering the entire process of substrate feeding, cooling and discharging. The limiting position can be flexibly adjusted according to the width of the substrate. In the film cooling and shaping stage, the water pump 32 fixed by the support seat 1 provides circulation power. The coolant is introduced into the cooling roller 18 through the first manifold 31 and the liquid inlet pipe 30, and then flows back through the liquid outlet pipe 33 and the second manifold 34 to form a closed-loop cooling cycle, realizing rapid and uniform heat exchange and cooling of the coated electrolyte membrane.

[0055] During the coating process, the positioning frame 35 at the top of the second support frame 14 and the third support frame 19 provides stable support for the top casting coating mechanism. The top cover 37 is bolted to the top of the storage tank 36. The drive motor 38 above the top cover 37 drives the transmission rod 39 to rotate. The stirring blade 42 at the bottom of the transmission rod 39 continuously stirs the composite electrolyte slurry in the tank. At the same time, the side rod 40 set at equal angles in the middle of the transmission rod 39 drives the anti-stick scraper 41 to stick to the inner wall of the storage tank 36 and scrape off the attached slurry in real time to prevent the slurry from sticking to the wall and drying. Finally, the slurry is precisely controlled by the solenoid valve 43 at the bottom of the storage tank 36 to control the discharge and flow rate, and then the quantitative, uniform and high-precision casting coating operation is completed through the coating seat 44.
