Description

Technical Field

[0001] This utility model relates to the field of new energy battery processing technology, specifically to a new energy battery casing spraying equipment. Background Technology

[0002] Spray coating of new energy battery casings is a key process in battery production. Its core is to uniformly and thoroughly coat the surface of the battery's metal casing with an insulating coating to ensure the safety and reliability of the battery module. Therefore, the ability of spray coating equipment to achieve high-quality, seamless coverage of various complex casing structures (especially internal cavities and edges) has become a key indicator for evaluating its performance.

[0003] Patent publication number CN221413563U discloses a new energy battery casing spraying equipment, including a housing, a rotating shaft movably sleeved on the inner surface of the housing, a rotating block fixedly installed on the outer surface of the rotating shaft, a fixing block fixedly installed on the outer surface of the rotating block away from the rotating shaft, a plurality of working plates fixedly connected to the inner surface of the fixing block, a plurality of sliding grooves formed on the outer surface of the plurality of working plates, a plurality of sliding rods movably sleeved on the inner surface of the plurality of sliding grooves, and a plurality of modules fixedly connected to the outer surface of the plurality of sliding rods away from the plurality of working plates.

[0004] To address the limitations of traditional spraying equipment, which cannot adapt to battery casings of different sizes due to fixed fixtures and suffer from low efficiency in single-sided spraying, existing technologies employ an adjustable modular fixture combined with a rotating mechanism. This allows the workpiece to rotate for multi-angle spraying. However, due to the fixed position of the spray gun, relying solely on the workpiece's rotational movement makes it difficult for the paint mist to effectively cover all surfaces of the workpiece's complex internal structure. This can lead to uneven coating thickness and incomplete coverage in critical insulation areas, posing a safety hazard of insulation failure. Furthermore, the efficiency of manually rotating the workpiece still needs improvement. Utility Model Content

[0005] The purpose of this invention is to provide a new energy battery casing spraying device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A new energy battery casing spraying equipment includes an outer casing, a material transfer spraying mechanism on one side of the outer casing, and a water curtain demisting mechanism on the other side of the outer casing.

[0018] The present invention will be further described in detail below with reference to embodiments: Example 1

[0019] like Figure 1-5As shown, this utility model provides a new energy battery casing spraying device, including an outer casing 1. A material transfer spraying mechanism 2 is provided on one side of the outer casing 1, and a water curtain demisting mechanism 3 is provided on the other side. The material transfer spraying mechanism 2 includes a spray pump 21, a paint solution tank 22, a first impeller 23, a second impeller 24, and a base 29. The bottoms of the spray pump 21, the paint solution tank 22, and the first impeller 23 are all fixedly connected to the top of the outer casing 1. One side of the second impeller 24 is fixedly connected to the outside of the outer casing 1. One end of the base 29 is fixedly connected to the inner wall of the outer casing 1. The input end of the spray pump 21 is connected to the inside of the paint solution tank 22 via a conduit. The output of the spray pump 21... The output end of the first impeller 23 is connected to the inside of the first impeller 23 through a conduit. The output end of the first impeller 23 is connected to the input end of the second impeller 24 through a conduit. The output shaft of the first impeller 23 is fixedly connected to a hook 210. The bottom of the hook 210 extends into the inside of the outer casing 1 of the device. One end of the base 29 is rotatably connected to a beam shroud 27. The inside of the beam shroud 27 is fixedly connected to a nozzle 28. One side of the beam shroud 27 is fixedly connected to a swing arm 26. The inside of the swing arm 26 is provided with a conduit and is connected to one end of the nozzle 28. The output end of the second impeller 24 is connected to the inside of the swing arm 26 through a conduit. The output shaft of the second impeller 24 is fixedly connected to a rocker arm 25. One end of the swing arm 26 is provided with a groove. The top end of the rocker arm 25 is slidably connected to the inside of the groove.

[0020] In this embodiment, the workpiece is suspended on the hook of the hook 210 during use, and the door of the device is closed to prevent spray leakage. Then, the spray pump 21 is turned on, and the spray pump 21 draws paint solution from the inside of the paint solution tank 22 and delivers it to the inside of the first impeller 23. The blades inside the first impeller 23 begin to rotate due to the impact of the liquid flow, which drives the hook 210 and the workpiece to rotate. The solution continues to flow along the conduit and enters the inside of the second impeller 24, which drives the rocker arm 25 to rotate. Since the top of the rocker arm 25 slides in the groove of the rocker arm 26, it will drive the rocker arm 26, the beam hood 27 and the nozzle 28 to swing up and down. The paint solution in the conduit is finally sprayed out from the nozzle 28. For the sake of convenience in showing the structure, the two impellers in the figure do not have a speed change structure. In actual production, gears can be added as needed to meet actual requirements. According to the above structural combination, the nozzle 28 can spray towards the workpiece, and the hook 210 drives the workpiece to rotate around the longitudinal axis, realizing a compound motion that can effectively eliminate spray dead angles and improve the reliability of the device. Example 2

[0021] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the water curtain defogging mechanism 3 includes a water curtain shower 32, a curved guide plate 33, and a circulating water tank 34. One side of the water curtain shower 32 and the curved guide plate 33 are fixedly connected to the other side of the inner wall of the outer casing 1 of the device. The surface of the circulating water tank 34 is slidably connected to the other side of the outer casing 1 of the device. One end of the circulating water tank 34 is fixedly connected to a water pump 31. The input end of the water pump 31 is connected to the bottom of the inner wall of the circulating water tank 34 through a conduit. The output end of the water pump 31 is connected to the inside of the water curtain shower 32 through a conduit. A fan 35 is fixedly connected to the outside of one side of the outer casing 1 of the device.

[0022] In this embodiment, the circulating water tank 34 needs to be replenished with clean water frequently. When spraying the workpiece, the fan 35 and water pump 31 are turned on. The fan 35 then blows air towards the workpiece, blowing the paint solution dispersed in the air to the other side of the device. After the water pump 31 is turned on, it draws water from the bottom of the circulating water tank 34 and delivers it to the water curtain shower head 32, from which the water flows out through the holes at the bottom of the water curtain shower head 32 and flows down the surface of the curved guide plate 33, forming a water curtain on the surface of the curved guide plate 33. The fan 35 blows the spray into the water curtain, where the paint will dissolve into the water and flow to the bottom of the device to be collected by the circulating water tank 34. Figure 1 As shown, the top of the device has a ventilation opening to allow the fan 35 to work normally. During use, a small amount of spray may escape from the ventilation opening. Depending on the actual situation, it may be necessary to add a pipe to guide it into the circulating water tank 34 below. After long-term use, the clean water inside the circulating water tank 34 will be contaminated by the paint and needs to be cleaned and replaced regularly.

[0023] The working principle of this new energy battery casing spraying equipment will be explained in detail below.

[0024] like Figure 1-5As shown, during use, the workpiece is suspended on the hook of hook 210, and the door of the device is closed to prevent spray leakage. Then, the spray pump 21 is turned on, and the spray pump 21 draws paint solution from the inside of the paint solution tank 22 and delivers it to the inside of the first impeller 23. The blades inside the first impeller 23 begin to rotate due to the impact of the liquid flow, which drives the hook 210 and the workpiece to rotate. The solution continues to flow along the conduit and enters the inside of the second impeller 24, which drives the rocker arm 25 to rotate. Since the top of the rocker arm 25 slides in the groove of the rocker arm 26, it will drive the rocker arm 26, the beam hood 27 and the nozzle 28 to swing up and down. The paint solution in the conduit is finally sprayed out from the nozzle 28. For the sake of showing the structure, the two impellers in the figure do not have a speed change structure. In actual production, gears can be added as needed to meet actual requirements. Based on the above structural combination, the nozzle 28 can spray towards the workpiece, and the hook 210 drives the workpiece to rotate around the longitudinal axis, achieving a motion that can effectively eliminate spraying dead angles and improve the reliability of the device. The circulating water tank 34 needs to be replenished with clean water frequently. When spraying the workpiece, the fan 35 and water pump 31 are turned on. The fan 35 then blows air towards the workpiece, blowing the paint solution dispersed in the air to the other side of the device. After the water pump 31 is turned on, water is drawn from the bottom of the circulating water tank 34 and delivered to the water curtain shower head 32, flowing out from the holes at the bottom of the water curtain shower head 32 and down the surface of the curved guide plate 33, forming a water curtain on the surface of the curved guide plate 33. The fan 35 blows the spray into the water curtain, where the paint will dissolve into the water and flow to the bottom of the device to be collected by the circulating water tank 34. Figure 1 As shown, the top of the device has a ventilation opening to allow the fan 35 to work normally. During use, a small amount of spray may escape from the ventilation opening. Depending on the actual situation, it may be necessary to add a pipe to guide it into the circulating water tank 34 below. After long-term use, the clean water inside the circulating water tank 34 will be contaminated by the paint and needs to be cleaned and replaced regularly.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
