Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a semi-automatic spraying equipment based on sodium-nickel batteries. Background Technology

[0002] With the rapid development of new energy technologies, sodium-nickel batteries, as a new type of energy storage device, have gradually become a research hotspot in the energy storage field due to their advantages such as high energy density, long cycle life, and safety. The second electrolyte in sodium-nickel batteries is a β”-alumina ceramic tube. However, β”-alumina ceramic tubes are sodium-repellent. For the battery to function properly, molten sodium needs to be evenly spread on the surface of the ceramic tube to reduce interfacial resistance. Therefore, an additional coating needs to be added to the outside of the ceramic tube to reduce the interfacial tension between the ceramic tube and sodium.

[0003] This additional coating is a slurry made from carbon powder, binder, wetting agent, and water in a specific ratio. This slurry is characterized by high viscosity and poor flowability. During battery production, this step involves manually applying the slurry to the surface of the ceramic tube using a brush. However, manual brushing is time-consuming and inefficient, and the efficiency further decreases as worker fatigue increases with working hours. With the continuous increase in sodium-ion battery production capacity, the efficiency of manual brushing cannot meet the demands of mass production.

[0004] Therefore, developing a device capable of efficiently coating the surface of sodium-nickel batteries has become an urgent technical problem to be solved. Utility Model Content

[0050] The purpose of this invention is to address the shortcomings of existing technologies by providing a semi-automatic spraying device based on a sodium-nickel battery.

[0051] Example

[0052] This embodiment provides a semi-automatic spraying device based on a sodium-nickel battery, such as... Figures 1-15 As shown, it includes a frame 1, a slurry supply structure 2, a weighing structure 3, a spraying structure 4, a negative pressure dust collection structure 5, and an electrical control system 6.

[0053] Frame 1 is the main structure of the equipment, constructed from aluminum profiles through welding and bolting, ensuring the overall stability and safety of the equipment. Frame 1 is divided into upper and lower parts by thick metal horizontal partitions. The upper part is the spraying chamber, and the lower part is the electrical control box. The spraying chamber is further divided into two identical left and right spraying chambers by vertical partitions.

[0054] In this embodiment, both the left and right spray booths are equipped with lifting doors 7. A touch screen 8 is installed on the side of the outer frame of the electrical control box. The touch screen 8 is electrically connected to the lifting doors 7 through wiring, etc., so that the lifting doors 7 can be controlled through the touch screen 8.

[0055] The slurry supply structure 2 includes a slurry supply tank 21, a quick-connect plug 22, a material pipe (not shown in the figure), and a spare material storage pipe 23.

[0056] The slurry supply tank 21 is usually a cylindrical container. In this embodiment, there are two slurry supply tanks 21, which are respectively set on the side of the frame on both sides of the spray booth. The quick-connect plug 22 is a standardized interface, and its number corresponds to the number of slurry supply tanks 21. In this embodiment, there is a spare storage pipe 23, which is set on the side of the frame outside the spray booth and is offset from the slurry supply tank 21.

[0057] One port of the quick-connect plug 22 is fixedly connected to the outlet of the slurry supply tank 21, and the other port of the quick-connect plug 22 is detachably connected to one end of the material tube. The other end of the material tube is detachably connected to the spraying structure 4, so that the material tube can be quickly replaced through the quick-connect plug 22.

[0058] The weighing structure 3 includes a weighing sensor 31, a weighing display 32, and connecting lines.

[0059] One end of the weighing sensor 31 is fixedly installed on one side of the top of the frame by a fixing block, and the other end of the weighing sensor 31 is fixedly connected to the top of the slurry supply tank by means of welding, threaded connection, etc. The weighing display 32 is fixedly installed on one end of the top of the frame 1 by means of welding, threaded connection, etc., and the weighing display 32 is connected to the weighing sensor 31 by a connecting line, thereby measuring the weight change of the slurry supply tank 21, calculating the amount of slurry consumed during the spraying process, and recording the data.

[0060] The spraying structure 4 includes a spray gun mechanism 41 and a rotating carrier mechanism 42.

[0061] The spray gun mechanism 41 includes a spray gun 411, a lead screw 412, a lead screw mounting component 413, a support base 414, a first motor 415, and a cable tray 416.

[0062] The support base 414 is integrally formed from a base plate, a back plate, and side plates. The base plate of the support base 414 is fixedly connected to the base plate inside the spraying chamber by welding, threads, etc., and the back plate of the support base 414 is fixedly connected to the side plate inside the spraying chamber by welding, threads, etc. The screw rod mounting component 413 is a square structure with a hollow interior and an open top. The back plate of the screw rod mounting component 413 is fixedly connected to the back plate of the support base 414 by threads, welding, etc. The screw rod 412 is set inside the screw rod mounting component 413. The housing of the first motor 415 is fixedly connected to the top of the screw rod mounting component 413, and the output shaft of the first motor 415 passes through the opening at the top of the screw rod mounting component 413 and is fixedly connected to the screw rod 412 set inside it by a coupling, so that the first motor 415 drives the screw rod 412 to rotate when it moves.

[0063] The spray gun 411 is typically elongated, with a corrosion-resistant nozzle at its head. A slider 417 is fixedly connected to the tail of the spray gun 411. The slider 417 has a slot in the middle, which fits onto one of the vertical plates of the support base 414. One side of the slider 417 is rotatably connected to a lead screw 412, so that when the lead screw 412 rotates under the action of the first motor 415, it drives the slider 417 to slide up and down along the vertical plate of the support base 414, thereby moving the spray gun 411 up and down. In this embodiment, a position sensor can also be installed on the slider 417 to provide feedback on the position information of the spray gun 411 to the electrical control system 6, ensuring the accuracy of the spraying 411.

[0064] The cable tray 416 is fixedly mounted on the back plate of the support base 414. The cable tray 414 is used to organize the wires of the first motor 415, spray gun 411, etc.

[0065] The rotating carrier mechanism 42 is located in the middle of the spraying chamber and is opposite to the spray gun mechanism 41. It includes a rotating platform 421, a dust cover 422, a cylinder 423, a dust-covering assembly 424, a fixing clamp 425, and a second motor 426.

[0066] The rotating platform 421 is a square structure connected by plates at the top and bottom. The upper square structure of the rotating platform 421 is equipped with slide rails 427 on both sides. The ceramic tube 9 to be sprayed is fixedly installed in the middle of the rotating platform 421.

[0067] The dust cover 422 includes two frame-shaped covers on the left and right sides. The interior of both sides of the dust cover 422 is slidably connected to the slide rail 427, so that the two dust covers 422 can slide left and right along the slide rail 427. An opening adapted to the ceramic tube 9 to be sprayed is opened on the top of the dust cover 422 and the side facing the ceramic tube 9 to be sprayed. In order to make up for the gap when the two dust covers 422 are closed, a dust-shielding assembly 424 is fixedly installed on the top of the opening of the dust cover 422. The dust-shielding assembly 424 includes an upper clamping plate 42. 41. Lower clamping plate 4242 and contoured silicone pad 4243. The contoured silicone pad 4243 is disposed between the upper clamping plate 4241 and the lower clamping plate 4242. The lower clamping plate 4242 is fixedly installed on the dust cover 422 by welding, threading, or other methods. The dust-shielding assembly 424 also has an opening adapted to the ceramic tube 9 to be sprayed, thereby filling any gaps that may exist when the dust cover 422 is closed, reducing impact force, protecting the solid electrolyte diaphragm from damage, and ensuring a better sealing effect to prevent slurry contamination of the lower part of the product. A fixing clamp 425 is fixedly installed at the bottom of the horizontal plate of the dust cover 422. The position of the fixing clamp 425 corresponds to that of the dust-shielding assembly 424 and is used to clamp the ceramic tube 9 to be sprayed, improving the stability of the ceramic tube 9 to be sprayed.

[0068] The second motor 426 and cylinder 423 are housed in the electrical control box. The output rod of the second motor 426 is fixedly connected to the rotating platform 421 via a coupling. The telescopic rods of the cylinder 423 are installed on both sides of the rotating platform 421. The piston rod of the cylinder 423 is connected to the dust cover 422 so that the second motor 426 rotates when it receives a command from the electrical control system 6, and drives the rotating platform 421 to rotate via the coupling. When the dust cover 422 needs to be opened, the piston rod of the cylinder 423 extends, pushing one side of the dust cover 422 to open outward. When the dust cover 422 needs to be closed, the piston rod of the cylinder 423 retracts, driving the dust cover 422 to close, covering the rotating platform 421 and preventing dust and slurry leakage. The cylinder 423 and the dust cover 422 can be connected by hinges or other means to realize the opening and closing of the dust cover 422.

[0069] The operator places the ceramic tube 9 to be sprayed onto the fixing fixture 425 and secures it using the clamping mechanism of the fixing fixture 425. The fixing fixture 425 is designed to ensure a firm fixation while avoiding damage to the product surface.

[0070] The negative pressure dust collection structure 5 includes a porous enclosure 51 and a negative pressure air intake 52.

[0071] The perforated enclosure 51 surrounds the perforated plates on both sides of the vertical partition of the spray booth, and the negative pressure suction port 52 is set on the back plate of the frame 1 so that the excess slurry and dust generated during the spraying process can be diffused to the outside of the equipment through the holes of the perforated enclosure 51 and the negative pressure suction port 52, thus protecting the working environment and product quality. In addition, the negative pressure suction port 52 has a reserved interface for connecting an external motor or spray tower to further realize the functions of dust collection and purification.

[0072] The electrical control system 6 includes a controller, a touch screen, electrical components (relays, contactors, circuit breakers, etc.), a motor driver, a cylinder controller, a weighing system interface, an alarm device, and a power module. The controller is connected to the touch screen 8, electrical components, a first motor driver, a second motor driver, a cylinder controller, a weighing structure interface, an alarm structure, and a power module via wiring.

[0073] Parameters are set and operation buttons are used via the touch screen 8. The controller controls the operation of various parts of the equipment. Electrical components realize circuit control and protection. The first motor driver, the second motor driver and the cylinder controller realize precise motion control. The weighing structure interface collects data. The alarm structure provides fault prompts. The power module provides stable power.

[0074] The controller is the core of the electrical control system. It is responsible for receiving and processing instructions from the touch screen and controlling the operation of various parts of the equipment (such as lifting doors, spraying devices, rotating loading fixtures, etc.).

[0075] In this embodiment, the controller is an existing PLC, such as the Siemens S7-1200 series, Omron CP1L series, etc. The specific control method can be referred to the existing technology, and will not be elaborated in this embodiment.

[0076] The specific usage method of the semi-automatic spraying equipment based on sodium-nickel batteries in this embodiment is as follows:

[0077] The slurry supply structure 2 is connected to the material pipe via quick-connect plug 22 to deliver the slurry to the spraying structure 4. After each spraying is completed, the weighing structure 3 measures the weight change of the slurry supply tank 21 via the weighing sensor 31, calculates the amount of slurry consumed during the spraying process, and records the data for subsequent analysis.

[0078] The ceramic tube 9 to be sprayed is manually placed on the rotating carrier mechanism 42 and fixed by the fixing clamp 425. The rotating platform 421 of the rotating carrier mechanism 42 rotates under the drive of the second motor 426, while the spray gun mechanism 41 moves on the slider 417 of the lead screw 412. The height and angle of the spray gun head can be adjusted as needed to ensure the uniformity of spraying.

[0079] The lifting door 7 of the spray booth opens or closes under the command of the electrical control system 6, ensuring that the spraying process is carried out in a closed environment and avoiding external interference.

[0080] Excess slurry and dust generated during the spraying process are sucked in through the porous enclosure 51 and the negative pressure suction port 52. The external motor or spray tower further treats these pollutants to ensure a clean working environment.

[0081] The electrical control system 6 receives operator commands via the touchscreen 8 and controls the movements of the lifting door 7, the spraying structure 4, and the rotating loading mechanism 42. Simultaneously, the system records weighing data and spraying parameters to facilitate subsequent process optimization.

[0082] The equipment in this embodiment can significantly improve production efficiency, increasing it by up to 5 times compared to manual brushing. The operator only needs to feed the material and operate the buttons, reducing manual intervention and shortening the production cycle.
