Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, specifically to an ultrasonic spraying machine for battery production. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes to generate an electric current. Traditional batteries are primarily cylindrical in shape. Ultrasonic spraying, also known as ultrasonic atomization, is a spraying process that utilizes ultrasonic atomization technology. Ultrasonic flatbed spraying equipment is specifically designed for glass, thin-film batteries, touchscreens, fuel cells, nanomaterials, etc., and offers advantages such as high spraying efficiency, low flow rate, uniform coating, small atomized particles, and the ability to be heated. Compared to traditional spraying methods like high-pressure spraying, ultrasonic flatbed spraying equipment allows for better control of spraying speed and flow rate, thus eliminating waste such as splattering during the spraying process.

[0003] However, when existing ultrasonic spraying machines spray the cylindrical surface of batteries, a large-area nozzle is required because the surface area of ​​the cylindrical surface is large. When spraying the two ends of the cylindrical body, the area of ​​the ends is smaller than that of the cylindrical body, which easily leads to material waste during the spraying process of the large-area nozzle. Manually changing the nozzle is time-consuming and labor-intensive, which affects production efficiency. Therefore, we provide an ultrasonic spraying machine for battery production. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasonic spraying machine for battery production, in order to solve the problems mentioned in the background art. When the existing ultrasonic spraying machine sprays the cylindrical surface of the battery, the large surface area of ​​the cylindrical surface requires the selection of a large-area structure nozzle. However, when spraying the two ends of the cylindrical body, the area of ​​the two ends is smaller than that of the cylindrical body, which easily leads to material waste during the spraying process of the large-area nozzle.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention achieves the effect of adjusting the spray range at the nozzle by setting a movable guide plate, a screw, a third motor, a through-hole plate, and a tapered hole. Fluid enters the fluid channel from the fluid inlet. The transducer converts high-frequency sound waves into mechanical energy and generates standing waves. When the liquid leaves the atomizing surface of the nozzle, it breaks into uniform micron-sized droplets, which are then uniformly coated onto the substrate surface by a certain amount of carrier gas, achieving the effect of ultrasonic atomization spraying. When spraying the battery column surface, rotating the screw outward causes the movable guide plate to press against the inner wall of the fluid channel, increasing the volume of the fluid channel to transport a large amount of fluid. At this time, the third motor at the spray nozzle drives the third transmission rod to rotate the through-hole plate, causing the tapered hole... The nozzle is transformed into an inverted cone shape, with the small orifice facing inward and the large orifice facing outward. The fluid atomizes at this point and is drawn outward by the carrier gas. Upon reaching the large orifice, the fine mist expands its dispersion range due to the increased orifice diameter, enabling it to coat the cylindrical surface of the battery. When spraying small areas at both ends of the battery, the screw is rotated inward, causing the movable guide plate and damping shaft to rotate. This rotation reduces the size of the fluid channel cavity and the flow rate. The third motor drives the third transmission rod to rotate the through-hole plate, transforming the conical orifice into a regular cone shape, with the large orifice facing inward and the small orifice facing outward. Due to the orifice diameter, the spray atomization area is relatively reduced, thus minimizing material waste without requiring the user to replace the nozzle.

[0020] 2. The first motor drives the first transmission rod and the rotating seat to rotate, so that the battery column can be fully sprayed in a rotating manner during the spraying process. After the battery column is sprayed, the electric cylinder drives the piston rod to extend, so that the clamping blocks on both sides are attached to the surface of the battery column for clamping and fixing. The second motor drives the second transmission rod and the clamping blocks to rotate, so that the battery is rotated. By rotating, the end face of the battery is facing the nozzle for end face spraying, so that each side of the battery is effectively sprayed.

[0021] 3. The second lead screw linear module is used to move the mounting bracket and the ultrasonic spraying mechanism, allowing the distance between the ultrasonic spraying mechanism and the battery to be adjusted. After spraying, the battery is clamped by the fixture and moved again to the electric unloading plate. The electric unloading plate is opened, allowing the battery to fall down the unloading channel into the rubber and plastic inclined plate. The rubber and plastic material has shock absorption properties, which can reduce the impact force. Through the inclined setting, the battery rolls into the collection trough. The collection trough collects the sprayed battery, giving the equipment automatic loading and unloading and distance adjustment functions. Users can take out the internal battery by opening the material removal cover, which is convenient for users. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Please see Figure 1-6 An embodiment of the present invention provides an ultrasonic spraying machine for battery production, comprising a spraying box 1 and an ultrasonic spraying mechanism 18. One end of the ultrasonic spraying mechanism 18 is provided with a fluid inlet 31, one end of the fluid inlet 31 is provided with a fluid channel 33, and the outer wall of the fluid channel 33 is provided with a transducer 32.

[0031] Also includes:

[0032] A guide plate 35 is adhered to the inner wall of the fluid channel 33. A movable guide plate 37 is rotatably connected to the lower part of the guide plate 35 via a damping shaft 36. A screw 34 is movably connected to one side of the movable guide plate 37 via a universal joint. A nut is threaded onto the screw 34 and fixedly connected to the outer wall of the fluid channel 33. A rubber block 38 is adhered to the lower end of the movable guide plate 37. Specifically, the fluid channel 33 has a square cross-section and a circular opening at its lower end. The movable guide plate 37 is a flat plate. The rubber block 38 deforms when the lower end of the movable guide plate 37 contacts the inner wall of the fluid channel 33, allowing the movable guide plate 37 to retract and be housed within the inner wall of the fluid channel 33, preventing it from being jammed and hindering its movement.

[0033] The spray nozzle 39 is fixedly installed at the lower end of the fluid channel 33. A through-hole plate 40 is fixedly installed at the middle position of the spray nozzle 39. Several tapered holes 43 are provided on the outer wall of the through-hole plate 40. A third motor 41 is fixedly installed on one side of the through-hole plate 40. A third transmission rod 42 is fixedly installed at the output end of the third motor 41. The other end of the third transmission rod 42 is fixedly connected to the through-hole plate 40, so that the output end of the third motor 41 is connected to the through-hole plate 40 through the third transmission rod 42 for driving the through-hole plate 40 to rotate.

[0034] The nozzle spray range is adjusted by setting up a movable guide plate 37, a screw 34, a third motor 41, a through-hole plate 40, and a tapered hole 43. Fluid enters the fluid channel 33 from the fluid inlet 31. The transducer 32 converts high-frequency sound waves into mechanical energy and generates standing waves. When the liquid leaves the atomizing surface of the nozzle, it breaks into uniform micron-sized droplets, which are then uniformly coated onto the substrate surface by a certain amount of carrier gas, achieving the effect of ultrasonic atomization spraying. When spraying the battery column surface, the screw 34 is rotated outwards, causing the movable guide plate 37 to press against the inner wall of the fluid channel 33, increasing the volume of the fluid channel 33 to supply a large amount of fluid. At this time, the third motor 41 drives the third transmission rod 42 to rotate the through-hole plate 40 at the spray nozzle 39, allowing the spray nozzle to spray. The conical orifice 43 is transformed into an inverted cone shape, with the smaller orifice facing inward and the larger orifice facing outward. The fluid atomizes at this point and is drawn outward by the carrier gas. Upon reaching the larger orifice, the fine mist expands its dispersion range due to the increased orifice diameter, enabling it to coat the cylindrical surface of the battery. When spraying a small area at both ends of the battery, the screw 34 is rotated inward, causing the movable guide plate 37 and the damping shaft 36 to rotate. This rotation reduces the size of the fluid channel 33's inner cavity, decreasing the flow rate. The third motor 41 drives the third transmission rod 42 to rotate the through-hole plate 40, transforming the conical orifice 43 into a positive cone shape, with the larger orifice facing inward and the smaller orifice facing outward. Due to the orifice diameter, the spray atomization area is relatively reduced, thus minimizing material waste without requiring the user to replace the nozzle.

[0035] Please see Figure 1 A feeding conveyor belt 2 is fixedly installed on one side of the spraying box 1. An electric cover plate 3 is fixedly installed above the end of the feeding conveyor belt 2 near the spraying box 1 via a hinge. An electric unloading plate 4 is fixedly installed inside the spraying box 1 near the electric cover plate 3. The feeding conveyor belt 2 feeds the battery into the interior. The electric cover plate 3 is mainly operated by a motor driving an electric shaft to rotate the cover plate to open and close. It is mainly used to open and block the feeding port. The electric unloading plate 4 works similarly. When it is necessary to unload, the motor is used to rotate and open the electric unloading plate 4 so that the battery can fall below. Under normal conditions, it is in a closed state and is used to temporarily store the batteries transported into the interior.

[0037] Please see Figure 1 , Figure 2 A rotating base 9 is installed below the front end of the ultrasonic spraying mechanism 18. A first motor 10 is fixedly installed below the rotating base 9. A first transmission rod 11 is provided at the output end of the first motor 10, and the output end of the first motor 10 is connected to the rotating base 9 through the first transmission rod 11. The first motor 10 is used to drive the first transmission rod 11 and the rotating base 9 to rotate, so that the battery column can be fully sprayed in a rotating manner during the spraying process.

[0038] Please see Figure 1 , Figure 2 Both sides of the rotating seat 9 are fixedly installed with support frames 12. An electric cylinder 13 is fixedly installed on the outer wall of the support frame 12. The electric cylinder 13 includes a piston rod 14. A second motor 15 is fixedly installed at one end of the piston rod 14. The electric cylinder 13 is connected to the second motor 15 through the piston rod 14. After the battery column is sprayed, the electric cylinder 13 drives the piston rod 14 to extend, so that the clamping blocks 17 on both sides are attached to the surface of the battery column for clamping and fixing.

[0039] Please see Figure 2 The output end of the second motor 15 is provided with a second transmission rod 16. One end of the second transmission rod 16 is fixedly installed with a clamping block 17, and the output end of the second motor 15 is connected to the clamping block 17 through the second transmission rod 16. The second motor 15 drives the second transmission rod 16 and the clamping block 17 to rotate, so that the battery is driven to rotate. By rotating, the end face of the battery is turned towards the nozzle for end face spraying operation, so that each side of the battery is effectively sprayed.

[0040] Please see Figure 1An ultrasonic generator 22 and an air supply box 23 are fixedly installed on one side of the first motor 10, and the ultrasonic generator 22 is electrically connected to the transducer 32.

The ultrasonic generator 22, the air supply box 23 and the liquid supply box 21 are all used to supply the ultrasonic spraying effect required.

[0041] Please see Figure 1 An installation bracket 19 is fixedly mounted on the outer wall of the ultrasonic spraying mechanism 18 by screws. A second lead screw linear module 20 is fixedly mounted on both the upper and lower ends of the installation bracket 19.

The second lead screw linear module 20 is used to drive the installation bracket 19 and the ultrasonic spraying mechanism 18 to move, so that the distance between the ultrasonic spraying mechanism 18 and the battery can be adjusted.

[0042] Please see Figure 1 Below the electric feeding plate 4, there is a feeding channel 24. Below the feeding channel 24, a rubber and plastic inclined plate 25 is fixedly installed. One end of the rubber and plastic inclined plate 25 is provided with a collection trough 26. One end of the collection trough 26 is fixedly installed with a material pick-up cover 27 by a hinge. After the battery is sprayed, it is clamped by the clamp 7 and moved to the electric feeding plate 4 again. The electric feeding plate 4 is opened, so that the battery falls down along the feeding channel 24 into the rubber and plastic inclined plate 25. The rubber and plastic material has shock absorption properties, which can reduce the impact force. Through the inclined setting, the battery rolls into the collection trough 26. The collection trough 26 collects the sprayed battery, so that the equipment has an automatic loading and unloading function. The user can take out the battery inside by opening the material pick-up cover 27, which is convenient for the user.

[0043] Please see Figure 1 An air purifier 28 is fixedly installed above the ultrasonic spraying mechanism 18. A mesh cover 29 is fixedly installed at the air inlet of the air purifier 28. An external exhaust pipe 30 is fixedly installed at the air outlet of the air purifier 28 through a flange. The air purifier 28 uses a fan to draw gas mixed with atomized particles. The gas is affected by the filter screen in the air purifier 28, which reduces the content of internal particles and causes the gas to be discharged to the external exhaust pipe 30, so that the equipment has a gas treatment function and improves its functionality.

[0044] Working principle: During use, the movable guide plate 37, screw 34, third motor 41, through-hole plate 40, and tapered hole 43 are used to adjust the spray range at the nozzle. Fluid enters the fluid channel 33 from the fluid inlet 31. The transducer 32 converts high-frequency sound waves into mechanical energy and generates standing waves. When the liquid leaves the atomizing surface of the nozzle, it breaks into uniform micron-sized droplets, which are then uniformly coated onto the substrate surface by a certain amount of carrier gas, achieving the effect of ultrasonic atomization spraying. When spraying the surface of the battery column, the screw 34 is rotated outward, causing the movable guide plate 37 to press against the inner wall of the fluid channel 33, increasing the volume of the fluid channel 33 to supply a large amount of fluid. At this time, the third motor 41 drives the third spray nozzle 39 to spray. The transmission rod 42 rotates the through-hole plate 40, causing the conical hole 43 to become an inverted cone shape, with the smaller hole facing inward and the larger hole facing outward. The fluid, atomized at this point, is drawn outward by the carrier gas. Upon reaching the larger hole, the fine mist's dispersion range expands due to the increased aperture, allowing it to coat the cylindrical surface of the battery. When spraying small areas at both ends of the battery, the screw 34 is rotated inward, causing the movable guide plate 37 and damping shaft 36 to rotate. This rotation reduces the size of the fluid channel 33's inner cavity, decreasing the flow rate. The third motor 41 drives the third transmission rod 42 to rotate the through-hole plate 40, causing the conical hole 43 to become a right cone shape, with the larger hole facing inward and the smaller hole facing outward. Due to the smaller aperture, the spray atomization area is relatively reduced, thus enabling spraying even when no additional atomization is needed. To reduce material waste when the user replaces the nozzle, the first motor 10 drives the first transmission rod 11 and the rotating seat 9 to rotate, allowing the battery column to be fully sprayed during the spraying process. After the battery column is sprayed, the electric cylinder 13 drives the piston rod 14 to extend, causing the clamping blocks 17 on both sides to clamp and fix the battery column surface. The second motor 15 drives the second transmission rod 16 and the clamping blocks 17 to rotate, causing the battery to rotate. This rotation aligns the end face of the battery with the nozzle for end face spraying, ensuring that each side of the battery is effectively sprayed. The feeding conveyor belt 2 feeds the battery into the interior. The electric cover 3 is mainly operated by a motor-driven electric shaft to rotate and open / close the cover, primarily used for opening and blocking the feed. Similarly, the electric feed plate 4 opens when feeding is needed, allowing the battery to fall below. Under normal conditions, it is closed, temporarily storing the batteries being fed inside. The first linear screw module 5 moves the lower assembly to the battery location, the electric push rod 6 extends downwards, and the electric telescopic rod 8 adjusts the clamps at both ends of the clamp 7 laterally to hold and fix the battery, moving it to the rotating seat 9 for placement. The second linear screw module 20 moves the mounting bracket 19 and the ultrasonic spraying mechanism 18, adjusting the distance between the ultrasonic spraying mechanism 18 and the battery. After spraying, the battery is clamped by the clamp 7 and moved again to the electric feed plate 4, opening the electric feed plate 4.The batteries fall along the feeding channel 24 into the rubber and plastic inclined plate 25. The rubber and plastic material has shock-absorbing properties, reducing impact. The inclined design causes the batteries to roll into the collection trough 26, which collects the coated batteries, enabling automatic loading and unloading. Users can easily retrieve the batteries by opening the unloading cover 27. The gas purifier 28 uses a fan to draw in gas mixed with atomized particles. The gas is filtered within the purifier 28, reducing the particle content, and then discharged through the exhaust pipe 30, providing gas treatment functionality and improving the equipment's overall performance.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
