Description

Technical Field

[0001] The invention relates to the technical field of batteries, in particular to an automated production line for zinc-bromine battery separators. Background Art

[0002] Zinc-bromine battery is an energy storage device that uses zinc and bromide as the main electrochemical reactants and is widely used in large-scale energy storage and the integration of renewable energy. The separator of the battery plays a vital role in its operation, mainly preventing direct contact between zinc and bromine in the battery, thus preventing short circuit.

[0003] For example, a Chinese patent with announcement number CN110137417A discloses a battery diaphragm manufacturing device, including a feeding mechanism and a conveyor belt mechanism connected to a conveying path, a cutting mechanism located on the conveying path of the feeding mechanism, a rolling mechanism located on the conveying path of the conveyor belt mechanism, and a constricting mechanism. The feeding mechanism and the conveyor belt mechanism are used for transmitting paper materials, the cutting mechanism cuts the paper materials into specific lengths, the rolling mechanism rolls the paper materials onto a reel, and the constricting mechanism shrinks and seals the ends of the paper materials to form a battery diaphragm. The battery diaphragm manufacturing device of the present invention has a high degree of mechanization, saves time and effort in the production of battery diaphragms, and has high work efficiency.

[0004] However, the above-mentioned battery diaphragm production device can only cut the substrate when making the battery diaphragm, but cannot perform the integrated operation of coating, drying and punching before. Furthermore, when performing these operations after the cutting is completed, the cut material needs to be transferred to other equipment for subsequent processes. The transfer process in the middle will consume extra time, resulting in a longer cycle of the entire battery diaphragm production and a lack of continuity between the various processes. This requires more manpower and time to coordinate the connection of the various processes, thereby reducing the efficiency of the entire production line. Summary of the invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Through the design of the connecting frame, the first transmission column, the conveyor belt, the first connecting plate, the second connecting plate, the second reduction motor, the slitting mechanism, the coating mechanism, the spacing control mechanism and the drying and punching mechanism, when making the diaphragm, the substrate can be rolled onto the outer surface of the release column of the first connecting plate, and the other end of the substrate is laid on the surface of the conveyor belt and fixedly connected to the outer surface of the winding column, so that the substrate fits into the concave part of the conveyor belt surface, and then the second reduction motor, the coating mechanism and the drying and punching mechanism can be started, and the second reduction motor can drive the conveyor belt mounted on the outer surface of the first transmission column to transmit, and the first transmission column is driven to rotate At the same time, the first gear on the other side will mesh with the transmission slitting mechanism to rotate relatively, and the driven slitting mechanism will cooperate with the conveyor belt to pull the substrate, and the pulled substrate will be rolled up on the outer surface by the winding column, and the coating mechanism started at the same time will apply the functional coating to the surface of the substrate and scrape it evenly, and then with the continuous conveying of the conveyor belt and the winding of the winding column, the substrate coated with the functional coating can be dried and punched at the lower end of the conveyor belt drying and punching mechanism, so that a diaphragm is formed between the substrate and the functional coating coated on the surface, and in the coating and drying process, the staff can pass according to the coating thickness and the distance from the drying. The spacing control mechanism is used to control the spacing between the coating mechanism and the conveyor belt according to the actual coating thickness requirements. The spacing control mechanism can also be adjusted according to the distance from the drying. By adjusting the spacing according to the drying distance, the state of the substrate before drying can be better controlled. As the diaphragm is continuously conveyed, the diaphragm can be rolled between the conveyor belt and the slitting mechanism, and then the slitting mechanism can cut the diaphragm into equal sizes. The two sides of the pulled diaphragm will be rolled to the outer surface of the winding column, making the whole process a continuous production process, starting from the laying of the substrate, through The coating, drying, punching, slitting and other processes are completed, and finally the remaining scraps after slitting the diaphragm are rolled up without any pause in between. This allows the production process to proceed continuously and stably, reducing the equipment idle time and labor costs that may be caused by process interruptions, and also helps to ensure the consistency of product quality. At the same time, the slitting mechanism and the winding column help to ensure the flatness of the substrate throughout the production process and avoid problems such as wrinkles. During the coating process, the flat substrate can enable the functional coating to be evenly coated, and during the punching process, it can also ensure the accuracy and quality of the punching, and during the slitting process, it can ensure the accuracy of the slitting size.

[0023] 2. Through the design of the second gear, the second transmission column and the slitting knife column, when the first reduction motor drives the first gear at one end of the first transmission column to rotate, the first gear will mesh with the second gear to rotate, so that the second gear can drive the second transmission column and the slitting knife column to rotate relative to each other, and the second transmission column touches the surface of the conveyor belt, so that the conveyor belt and the second transmission column can rotate synchronously relative to each other, and the diaphragm between the second transmission column and the conveyor belt can be rolled inside and exert a pulling effect, and after the manufactured diaphragm is conveyed and pulled between the conveyor belt and the slitting knife column, the slitting knife column can be The cutting column rolls over the surface of the diaphragm to cut the diaphragm into equal sizes, and the diaphragm scraps after cutting will be rolled up on the surface by the winding column, wherein the diaphragm passing between the second transmission column and the conveyor belt is rolled and exerted with a pulling effect, and the two rotate synchronously relative to each other. This pulling and synchronous rotation mechanism can ensure the stability of the tension of the diaphragm during the slitting process. The stable tension helps to improve the slitting accuracy and avoid problems such as diaphragm deformation or incomplete cutting caused by uneven tension during the slitting process. Moreover, the pulling effect can also make the diaphragm smoothly transmitted on the production line, thereby improving the efficiency of the entire production process.

[0024] 3. Through the design of the storage box, air lift pump, unfolding plate, discharge pipe, branch pipe, scraper, frame, connecting arm and electric push rod, while the substrate is being transported by the conveyor belt, the air lift pump can inject air into the storage box so that the storage box pushes the stored functional coating into the discharge pipe, and the discharge pipe can apply the functional coating on the substrate through the branch pipe, and the scraper at the lower end of the outer surface of the discharge pipe can evenly scrape and apply the coated functional coating on the surface of the substrate, wherein the inner groove of the conveyor belt can prevent the excess coating from being scraped and flowing to both sides, so that the excess coating can be continued to be scraped by the scraper on the surface of the substrate at the rear end, and in the process of scraping the functional coating, the frame at one end of the piston rod can be pushed or pulled by starting the electric push rod, and the frame will be rotated through the connecting arms on both sides, and the frame can be pushed by the piston rod of the electric push rod. The distance between the frame and the conveyor belt can be reduced, and when pulled, the distance between the frame and the conveyor belt can be increased, so that the distance between the scraper and the conveyor belt can be adjusted, and the staff can adjust the coating thickness according to the actual requirements;

[0025] After use, the staff can release the pressure on the flip plate by unscrewing the hand wheel from the outer surface thread of the threaded column, so that the staff can flip and unfold the flip plate to display the branch pipe and the scraper in front of the staff for maintenance operations.

[0026] 4. Through the design of infrared radiation heater, sleeve frame and laser puncher, when the functional material is coated on the surface of the substrate, it will be transported by the conveyor belt to the lower end of another group of frames, and the infrared radiation heater fixedly installed in the other group of frames will dry the coated material on the surface of the substrate. This drying method can quickly and effectively remove moisture or solvent in the coating material, so that the coating material is solidified on the surface of the substrate, and after drying, it can be transported by the conveyor belt to the lower end of the laser puncher, and the laser puncher can irradiate the surface of the diaphragm with a high-energy light beam to locally heat the material and melt or evaporate it, thereby forming holes. Laser drilling has the characteristics of high precision and can accurately control the size, shape and distribution of the holes. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Among them, two groups of spacing adjustment mechanisms 4 are rotatably installed on both sides of the connecting frame 1, and the upper surfaces of the two groups of spacing adjustment mechanisms 4 are respectively fixedly installed with a coating mechanism 3 and a drying and punching mechanism 5. The coating mechanism 3 and the drying and punching mechanism 5 are located at the upper end of the conveyor belt 103 through the overhead spacing adjustment mechanism 4, so that the coating end of the coating mechanism 3 can be inserted between the two groups of enclosure plates 102 and the concave parts of the conveyor belt 103, and touch the surface of the conveyor belt 103, so that it can evenly coat the functional coating on the surface of the substrate. The functional coating can be a polymer, a conductive material, etc. The drying and punching mechanism 5 can dry and punch the coated substrate;

[0041] Among them, a first gear 110 is fixedly installed on the outer surface of the other end of the first transmission column 101 fixedly connected to the output shaft of the first reduction motor 108. The first gear 110 is engaged with the slitting mechanism 2. The slitting mechanism 2 rotates between the two sets of connecting frames 1 and is located at the upper end of the first transmission column 101 and contacts the surface of the conveyor belt 103, so that it can perform slitting operations on the diaphragm transported to this position.

[0042] Through the design of the connecting frame 1, the first transmission column 101, the conveyor belt 103, the first connecting plate 104, the second connecting plate 105, the second reduction motor 107, the slitting mechanism 2, the coating mechanism 3, the spacing adjustment mechanism 4 and the drying and punching mechanism 5, when making the diaphragm, the substrate can be rolled onto the outer surface of the release column of the first connecting plate 104, and the other end of the substrate is laid on the surface of the conveyor belt 103 and fixedly connected to the outer surface of the winding column 106, so that the substrate fits into the concave part of the surface of the conveyor belt 103, and then the second reduction motor 107, the coating mechanism 3 and the drying and punching mechanism 5 can be started, and the second reduction motor 107 can drive the first transmission column 101 to drive the outer surface of the substrate.

By adjusting the spacing according to the drying distance, the state of the substrate before drying can be better controlled, and as the diaphragm is continuously conveyed, the diaphragm can be rolled between the conveyor belt 103 and the slitting mechanism 2, and then the slitting mechanism 2 can cut the diaphragm into equal sizes, and the two sides of the pulled diaphragm will be rolled to the outer surface of the winding column 106, so that the whole process is a continuous The continuous production process starts with the laying of the substrate, goes through coating, drying, punching, slitting and other processes, and finally rolls up the remaining scraps after slitting the diaphragm, without any pause in between. This allows the production process to proceed continuously and stably, reducing the equipment idle time and labor costs that may be caused by process interruptions, and also helps to ensure the consistency of product quality. At the same time, the slitting mechanism 2 and the winding column 106 help to ensure the flatness of the substrate throughout the production process, avoiding problems such as wrinkles. During the coating process, the flat substrate can enable the functional coating to be evenly coated, and during the punching process, it can also ensure the accuracy and quality of the punching, and during the slitting process, it can ensure the accuracy of the slitting size.

Moreover, the pulling effect can also make the diaphragm smoothly transmitted on the production line, thereby improving the efficiency of the entire production process.

[0052] Through the design of the storage box 301, the air lift pump 303, the unfolding plate 302, the discharge pipe 311, the branch pipe 310, the scraper 309, the frame 401, the connecting arm 402 and the electric push rod 403, while the substrate is being transported by the conveyor belt 103, the air lift pump 303 can inject air into the storage box 301, so that the storage box 301 pushes the stored functional coating into the discharge pipe 311, and the discharge pipe 311 can apply the functional coating on the substrate through the branch pipe 310, and the scraper 309 at the lower end of the outer surface of the discharge pipe 311 can evenly scrape and apply the coated functional coating on the surface of the substrate, wherein the inner groove position of the conveyor belt 103 is used to avoid excess The paint is scraped and flows to both sides, so that the excess paint can be scraped by the scraper 309 to the surface of the substrate at the rear end. In the process of scraping the functional paint, the electric push rod 403 can be started to push or pull the frame 401 at one end of the piston rod, and the frame 401 can be rotated through the connecting arms 402 on both sides. When the frame 401 is pushed by the piston rod of the electric push rod 403, the distance between the frame 401 and the conveyor belt 103 can be reduced, and when it is pulled, the distance between the frame 401 and the conveyor belt 103 can be increased, thereby adjusting the distance between the scraper 309 and the conveyor belt 103, so that the staff can adjust the coating thickness according to the actual coating thickness requirements;

[0053] After use, the staff can release the pressure on the flip plate 302 by unscrewing the hand wheel 305 from the outer surface thread of the threaded column 306, so that the staff can flip and unfold the flip plate 302 to display the branch pipe 310 and the scraper 309 in front of the staff for maintenance operations.

[0054] like Figure 8 As shown, the drying and punching mechanism 5 includes an infrared radiation heater 501, which is fixedly installed in another set of frames 401, so that the infrared radiation heater 501 can dry the functional coating on the surface of the substrate.

[0055] A fastening plate 502 is fixedly mounted on one end of the frame 401 , a sleeve frame 503 is fixedly mounted on one end of the fastening plate 502 , and a laser puncher 504 is fixedly mounted inside the sleeve frame 503 , so that the laser puncher 504 can punch holes in the formed diaphragm after drying.

[0056] Through the design of the infrared radiation heater 501, the sleeve frame 503 and the laser punch 504, when the functional material is coated on the surface of the substrate, it will be transported to the lower end of another group of frames 401 by the conveyor belt 103, and the infrared radiation heater 501 fixedly installed in the other group of frames 401 will dry the coated material on the surface of the substrate. This drying method can quickly and effectively remove moisture or solvent in the coating material, so that the coating material is solidified on the surface of the substrate, and after drying, it can be transported to the lower end of the laser punch 504 by the conveyor belt 103, and the laser punch 504 can irradiate the surface of the diaphragm with a high-energy light beam to locally heat the material and melt or evaporate it, thereby forming holes. Laser drilling has the characteristics of high precision and can accurately control the size, shape and distribution of the holes.

[0057] In this embodiment, considering that the distribution of the coating on the substrate is affected by many factors, such as the viscosity of the coating, the coating speed, the pressure of the scraper, etc., a complex equation based on fluid mechanics and coating theory can be introduced to describe this process. For simplicity, it can be assumed that the distribution of the coating on the substrate can be approximated as a two-dimensional diffusion process and is affected by the scraper pressure.

[0058] The coating distribution uniformity equation is as follows:

[0059]

[0060] in:

[0061] C is the concentration distribution of the coating on the substrate (unit: g / m 2 );

[0062] t is time (unit: s);

[0063] D is the diffusion coefficient of the coating (unit: m 2 / s), which describes the ability of a coating to spread spontaneously on a substrate;

[0064] is the Laplace operator, describing the second-order derivative in space;

[0065] is the coating velocity vector (unit: m / s), which describes the speed at which the coating is pushed by the scraper on the substrate;

[0067] is the gradient operator, describing the first-order derivative in space;

[0068] k is the coefficient of influence of scraper pressure on coating distribution (unit: g / (m 2 ·Pa));

[0069] P is the pressure of the scraper on the substrate (unit: Pa).

[0070] Simulation and optimization: Through numerical simulation, this equation can be solved to predict the uniformity of coating distribution on the substrate under different process parameters. This helps to optimize process parameters and improve coating uniformity during the production line design stage.

[0071] Parameter adjustment: In the actual production process, the effectiveness of the equation can be verified by adjusting parameters such as scraper pressure and coating speed and observing the changes in coating distribution. This helps to adjust process parameters in real time to ensure that the uniformity of the coating is optimal.

[0072] Technical effects:

[0073] Improve coating uniformity: By introducing this equation, the distribution process of coating on the substrate can be described more accurately, thereby guiding the optimization of process parameters and improving coating uniformity.

[0074] Reduce production costs: Optimizing process parameters can reduce coating waste and the generation of defective products, thereby reducing production costs.

[0075] Improve product quality: Improved coating uniformity helps improve the quality and performance of the final product, such as the conductivity and mechanical strength of the diaphragm.

[0076] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when making the diaphragm, the substrate can be rolled up and sheathed on the outer surface of the release column of the first connecting plate 104, and the other end of the substrate is laid on the surface of the conveyor belt 103 and fixedly connected to the outer surface of the winding column 106, so that the substrate fits into the concave part of the surface of the conveyor belt 103, and then the second reduction motor 107, the air lift pump 303 and the infrared radiation heater 501 can be started, and the second reduction motor 107 can drive the conveyor belt 103 sheathed on the outer surface of the first transmission column 101 to transmit, and the first transmission column 101 is driven to rotate, and the second gear 201 is driven by the other side through the first gear 110 to drive the second transmission column 202 and the slitting knife column 2 03 rotates relative to each other, and the second transmission column 202 contacts the surface of the conveyor belt 103, so that the conveyor belt 103 and the second transmission column 202 can rotate relatively synchronously, and the diaphragm between the second transmission column 202 and the conveyor belt 103 can be rolled inside and exert a pulling effect, and while the substrate is being transported by the conveyor belt 103, the air lift pump 303 can inject air into the storage box 301, so that the storage box 301 pushes the stored functional coating into the discharge pipe 311, and the discharge pipe 311 can apply the functional coating on the substrate through the branch pipe 310, and the scraper 309 at the lower end of the outer surface of the discharge pipe 311 can evenly scrape and apply the coated functional coating on the surface of the substrate, wherein the inner groove position of the conveyor belt 103 is used to pass through the inner groove position of the conveyor belt 103. , so that it can prevent excess paint from being scraped and flowing to both sides, so that the excess paint can be scraped by the scraper 309 to the surface of the substrate at the rear end, and in the process of scraping the functional paint, the frame 401 at one end of the piston rod can be pushed or pulled by starting the electric push rod 403, and the frame 401 will rotate through the connecting arms 402 on both sides, and when the frame 401 is pushed by the piston rod of the electric push rod 403, the distance between the frame 401 and the conveyor belt 103 can be reduced, and when it is pulled, the distance between the frame 401 and the conveyor belt 103 can be increased, thereby adjusting the distance between the scraper 309 and the conveyor belt 103, so that the staff can adjust the distance between the scraper 309 and the conveyor belt 103 according to the actual coating thickness requirements, when the surface of the substrate is coated with functional paint. After the material is coated, it will be conveyed by the conveyor belt 103 to the lower end of another group of frames 401, and the infrared radiation heater 501 fixedly installed in the other group of frames 401 will dry the coating material on the surface of the substrate. This drying method can quickly and effectively remove the moisture or solvent in the coating material, so that the coating material is solidified on the surface of the substrate, and after drying, it can be conveyed by the conveyor belt 103 to the lower end of the laser punch 504, and the laser punch 504 can irradiate the surface of the diaphragm with a high-energy light beam to locally heat the material and make it melt or evaporate, thereby forming holes, that is, completing the production of the diaphragm. Subsequently, as the conveyor belt 103 continues to transport, the produced diaphragm is transported and pulled between the conveyor belt 103 and the slitting knife column 203,The slitting blade column 203 can roll over the surface of the diaphragm to cut the diaphragm into equal sizes, and the slitting diaphragm scraps will be rolled up on the surface by the rolling column 106.

[0077] In summary: The automated production line for zinc-bromine battery separators is a continuous production process, starting from the laying of the substrate, through coating, drying, punching, slitting and other processes, and finally rolling up the remaining scraps after slitting the separators, without any pauses in between. This enables the production process to proceed continuously and stably, reducing the equipment idle time and labor costs that may be caused by process interruptions, and also helps to ensure the consistency of product quality.
