Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing, and in particular to a continuous coating plate humidification device. Background Technology

[0002] Currently, in the production of power batteries for electric bicycles, factories use continuous casting and continuous casting-rolling to manufacture grids. Then, qualified grids undergo continuous coating, slitting, paper covering, surface drying, and stacking. However, the slitting, small, wet plates are relatively soft and easily deformed. To ensure the cured plates are straight and neat, a close-packed stacking method is used for curing, i.e., stacked flat or stacked horizontally on a curing rack. It is known that sufficient moisture is required during curing to ensure smooth conversion. However, after surface drying, significant water loss often occurs, and the wet plates are continuously losing water due to their high temperature before stacking. Close-packing makes water replenishment during stacking ineffective. Therefore, it is necessary to replenish and humidify the plates after surface drying and before stacking, without affecting the absorption effect during wrapping.

[0003] For example, Chinese patent CN219540728U discloses a lead-acid battery plate humidification device, including a curing frame and multiple separator assemblies. The curing frame includes two symmetrically arranged supports, the first and second, which have identical structures. Multiple reinforcing rods are arranged between the first and second supports. The first support includes two uprights and multiple mounting plates. A water supply pipe is provided on one side of the curing frame, with an inlet at the bottom and an outlet at the top. A valve is provided at the outlet. Multiple interfaces are provided on the water supply pipe, with a buckle connected to one end of each interface. The separator assemblies include multiple separators, with multiple grooves at the bottom of each separator. Multiple branch pipes are arranged within the grooves, with one end of each branch pipe closed and the other end secured with a buckle. Multiple nozzles are evenly arranged on the lower side of each branch pipe. This utility model achieves uniform humidification of the plates by evenly distributing nozzles at the bottom of the separators, ensuring the humidification effect of the plates. However, the above-mentioned utility model can only replenish water and moisturize lead-acid batteries, and the moisturizing process is achieved by spraying. The humidification effect is not ideal for coated plates and may even cause the plates to stick together. Utility Model Content

[0004] In view of the problems in the prior art that humidifying continuously coated plates may cause adhesion between the plates and the humidification effect is not ideal, this utility model proposes a humidification device that uses atomized water vapor to humidify continuously coated plates, which has an ideal humidification effect, can continuously humidify the plates, and will not cause adhesion between the plates.

[0005] To achieve the above-mentioned technical effects, this utility model is proposed;

[0006] A continuous-coating plate humidification device includes an atomizing pipeline and a humidification box assembly connected to the atomizing pipeline. The atomizing pipeline includes a high-frequency atomizer, a positive fan connected to the high-frequency atomizer, a negative fan connected to the positive fan, the high-frequency atomizer connected to the bottom of the humidification box assembly, and the negative fan connected to a collection box at the top of the humidification box assembly. A conveyor belt assembly is installed in the humidification box assembly.

[0007] The positive and negative fans generate positive and negative pressure respectively, causing the atomized water vapor produced by the high-frequency atomizer to form a mist. The mist enters the humidification box assembly from the bottom and humidifies and replenishes the plates on the conveyor belt assembly inside the humidification box assembly. Then, the mist is collected by the collection box and enters the atomization pipeline, which then transports it to the high-frequency atomizer.

[0008] The humidification chamber assembly includes an isolation cover with a humidification inlet at its bottom. The humidification inlet is connected to the high-frequency atomizer via a humidification output pipe. The isolation cover is the main structure of the humidification chamber assembly and can be made of transparent material for easy observation of its internal operation.

[0009] The conveyor belt assembly is installed inside the isolation cover. The conveyor belt assembly includes a perforated conveyor belt and two drive rollers. The perforated conveyor belt is sleeved on the two drive rollers. The surface of the perforated conveyor belt is provided with several through holes.

[0010] The isolation cover has corresponding material windows on its two side panels. The conveyor belt assembly passes through the two material windows and has a material conveying port between it and the two material windows.

[0011] The isolation hood is equipped with a humidification perforated plate, which has several through holes and is located near the humidification inlet. The humidification perforated plate makes the mist flow into the humidification chamber assembly more uniform and increases the flow rate of the mist flowing through the through holes.

[0012] The top of the isolation cover is equipped with several short recovery pipes, which connect the collection box and the isolation cover. The arrangement of the short recovery pipes reduces the area of ​​the top of the isolation cover, thereby reducing the condensation of atomized water vapor on the top of the isolation cover.

[0013] The positive fan and the negative fan are connected by a recovery pipe, which has multiple bends.

[0014] The humidification chamber assembly is equipped with a temperature and humidity sensor on its top. The temperature and humidity sensor is used to guide the adjustment of the positive and negative air blowers.

[0015] The beneficial effects of this utility model are:

[0016] The continuous coating electrode humidification device proposed in this utility model can continuously humidify the electrode plates, and the atomizing pipeline can recycle the atomized water vapor, resulting in good humidification effect and preventing adhesion between the electrode plates.

[0025] In the manufacturing process of electric bicycle battery grids, continuous coating and slitting, paper covering, surface drying, and sheet collection are required. After the surface drying process, the plates need to be humidified to ensure the smooth progress of the conversion process. However, the plates themselves are at a high temperature and are constantly losing water, so humidification and water replenishment are necessary after surface drying and before sheet collection. Currently, most battery plate humidification and water replenishment methods involve spraying, which may lead to adhesion between plates in the continuous coating process and is not suitable for the continuous coating process used in this invention. Therefore, this invention proposes a continuous coating plate humidification device that can continuously humidify and replenish water without causing adhesion between plates, and has a better humidification effect than existing technologies. The following specific embodiments illustrate the implementation of this invention. Those skilled in the art can easily understand other advantages and effects of this invention from the content disclosed in this specification. The preferred embodiments of the continuous coating plate humidification device are described below.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, the continuous coating electrode humidification device in this embodiment includes an atomizing pipe 1 and a humidification box assembly 2 connected to the atomizing pipe 1. The atomizing pipe 1 includes a high-frequency atomizer 11, a positive fan 12 connected to the high-frequency atomizer 11, a negative fan 13 connected to the positive fan 12, the high-frequency atomizer 11 connected to the bottom of the humidification box assembly 2, and the negative fan 13 connected to a collection box 26 at the top of the humidification box assembly 2. A conveyor belt assembly 21 passes through the humidification box assembly 2. The atomizing pipe 1 atomizes the liquid and transports the resulting mist stream into the humidification box assembly 2. The conveyor belt assembly 21 passes through the humidification box assembly 2, and the micro water droplets in the mist stream enter the gaps of the wet plate lead paste and are partially absorbed, completing the water replenishment. The remaining mist stream returns to the high-frequency atomizer 11 through the collection box 26 at the top of the humidification box assembly 2. The high-frequency atomizer 11 is connected to a positive fan 12 at its upper end. The positive fan 12 is responsible for generating positive pressure on the high-frequency atomizer 11, sending out the water mist generated by the high-frequency atomizer 11 to form a mist stream. The other end of the positive fan 12 is connected to a negative fan 13. The negative fan 13 is responsible for generating negative pressure in the humidification box, and recycling the remaining mist stream after humidification back to the high-frequency atomizer 11 to form a mist stream circulation. The humidification box assembly 2 is the main place for humidifying the electrode plate. It is equipped with a conveyor belt assembly 21, which is used to transport the electrode plate into the humidification box assembly 2 and transport it out of the humidification box assembly 2 after humidification. The collection box 26 is located at the top of the humidification box assembly 2 and is used to collect the remaining mist stream in the humidification box assembly 2 and collect the mist stream, which is then recycled back to the high-frequency atomizer 11 by the negative fan 13.

[0028] like Figure 1 and Figure 2 As shown, the humidification box assembly 2 includes an isolation cover 22, and a humidification inlet 23 is provided at the bottom of the isolation cover 22. The humidification inlet 23 is connected to the high-frequency atomizer 11 through the humidification output pipe 15. A humidification perforation plate 24 is provided in the isolation cover 22, and a number of through holes are provided on the humidification perforation plate 24. The humidification perforation plate 24 is close to the humidification inlet 23. The main body of the humidifier assembly is an isolation cover 22. In this embodiment, the isolation cover 22 is made of transparent material and has an overall rectangular structure, which facilitates observation of the working conditions inside the isolation cover 22. A humidification inlet 23 is provided at the bottom of the isolation cover 22. The humidification inlet 23 is a four-cornered pyramid shape. Its large diameter end is connected to the bottom surface of the isolation cover 22, and its small diameter end is connected to the high-frequency atomizer 11 through the humidification output pipe 15. A humidification perforated plate 24 is provided at the bottom inside the isolation cover 22. In this embodiment, the humidification perforated plate 24 completely occupies the bottom surface of the isolation cover 22. Several through holes are provided on the humidification perforated plate 24. The mist flow from the humidification inlet 23 passes through the through holes on the humidification perforated plate 24 to form several small mist flows. This process avoids the mist flow from accumulating at the humidification inlet 23 or the mist flow from being uneven when passing through the conveyor belt assembly 21. The through holes on the humidification perforated plate 24 can increase the flow rate of the mist flow to a certain extent and enhance the humidification effect.

[0029] like Figure 1 and Figure 2 As shown, the conveyor belt assembly 21 is installed in the isolation cover 22. The conveyor belt assembly 21 includes a perforated conveyor belt 212 and two drive rollers 211. The perforated conveyor belt 212 is sleeved on the two drive rollers 211. The surface of the perforated conveyor belt 212 is provided with several through holes. The conveyor belt assembly 21 is used to transport the electrode plates, feeding them into the isolation cover 22 for humidification, and then conveying them out of the isolation cover 22 after humidification. The two drive rollers 211 have identical structures, with widths close to the internal width of the isolation cover 22. The width of the perforated conveyor belt 212 is the same as the width of the drive rollers 211. The two drive rollers 211 are parallel to each other at both ends along the length of the isolation cover 22, supporting the perforated conveyor belt 212. An externally connected motor or other drive device rotates the drive rollers 211, causing the perforated belt to rotate around the axis of the two drive rollers 211, thus moving the electrode plates on the perforated conveyor belt 212. Several through holes are provided on the surface of the perforated conveyor belt 212 to facilitate the flow of mist from bottom to top through the perforated conveyor belt 212 and into contact with the electrode plates.

[0030] like Figure 2 As shown, the isolation cover 22 has material windows 221 corresponding to the two side plates on opposite sides. The conveyor belt assembly 21 passes through the two material windows 221, and there is a material conveying port 222 between it and the two material windows 221. In this embodiment, the isolation cover 22 has two material windows 221 opposite to each other on two smaller side plates. The opening area of ​​the two material windows 221 is the same, and the height relative to the humidifying perforated plate 24 is the same. The material windows 221 are used to pass through the conveyor belt assembly 21, and there is a material conveying port 222 between them and the perforated conveyor belt located above. The electrode plate enters the interior of the isolation cover 22 through the material conveying port 222. The size of the opening of the material conveying port 222 is adjusted according to the actual size of the electrode plate.

[0031] like Figure 2 As shown, the top of the isolation cover 22 is provided with several short recovery pipes 25, which connect the collection box 26 and the isolation cover 22. In this embodiment, nine short recovery pipes 25 are arranged at intervals along the length of the isolation cover 22 between the isolation cover 22 and the collection box 26. The design of the short recovery pipes 25 reduces the area of ​​the top surface of the isolation cover 22. That is, by adopting a design similar to the humidification inlet 23 described above, the area of ​​the top of the isolation cover 22 will be much larger, making it easier for water to accumulate on the top of the isolation cover 22.

[0032] like Figure 2 As shown, the positive fan 12 and the negative fan 13 are connected by a recovery pipe 14, which has multiple bends. In this embodiment, the recovery pipe 14 between the positive fan 12 and the negative fan 13 has a much smaller inner diameter than the humidification output pipe 15 and has two bends, which saves space for the electrode plate conveying of the humidification box assembly 2.

[0033] like Figure 2 and Figure 3 As shown, a temperature and humidity sensor 27 is provided on the top of the humidification box assembly 2. The temperature and humidity sensor 27 monitors the temperature and humidity inside the humidification box assembly 2 to regulate the temperature and humidity parameters inside the humidification box assembly 2. Automated equipment can be added in addition to the humidification device in this embodiment to achieve automated control.

[0034] The working process of the continuous coating plate humidification device in this embodiment:

[0035] Before coating the plate, the operator turns on the high-frequency atomizer 11, positive fan 12, and negative fan 13. The high-frequency electric field in the atomizer causes the internal liquid to generate a large number of tiny bubbles. These bubbles quickly break into fine mist particles. The mist particles are formed into a uniform mist flow by the positive fan 12. The mist flow enters the humidification inlet 23 of the humidification box assembly 2 through the humidification output pipe 15. After passing through the humidification perforated plate 24, the mist flow forms multiple mist flows, and the flow rate increases. The mist flow passes through the through holes on the perforated conveyor belt 212 and is then driven by the negative fan 13 to enter the collection box 26 through the recovery short pipe 25. After being collected in the collection box 26, the atomized flow returns to the high-frequency atomizer 11 via the negative fan 13, the recovery pipe 14, and the positive fan 12. The external motor is then turned on to drive the transmission roller. Rotation of 211 drives the perforated conveyor belt 212 to move. The operator places the electrode plate through the material conveying port 222 on one side. The electrode plate enters the isolation cover 22. The micro water droplets in the mist humidify and replenish the electrode plate. Part of the humidified mist is collected by the collection box 26. The temperature and humidity sensor 27 located on the top of the isolation cover 22 guides the adjustment of the positive fan 12 and the negative fan 13. It can monitor the changes in temperature and humidity inside the isolation cover 22 in real time to meet the humidification needs of the electrode plate in different temperature and humidity environments. During this process, no obvious water remains on the surface of the electrode plate, which can prevent the adhesion of adjacent electrode plates and will not affect the subsequent assembly stage of wrapping and suction. Moreover, the pure water at the lower temperature can cool the electrode plate after atomization, reducing water evaporation.

[0036] In this embodiment, the cooperation between the atomizing pipeline and the humidification box assembly enables the electrode humidification process to proceed continuously; the humidification perforated plate makes the atomized flow more uniform inside the humidification box assembly, increasing the flow rate; the electrode plates on the perforated conveyor belt operate in sections, avoiding adhesion between the electrode plates; the positive and negative fans are regulated by temperature and humidity sensors, resulting in good humidification effect; the low-temperature mist flow can cool the electrode plates while humidifying them, which is of practical significance.

[0037] Example 2

[0038] The current methods for humidifying and replenishing battery plates, which mostly involve spraying, may lead to adhesion between plates in continuous coating processes. This method is not suitable for humidifying plates in the continuous coating process used in this invention. Therefore, this invention proposes a continuous coating plate humidification device that can continuously humidify and replenish water without causing adhesion between plates, and also has a better humidification effect than existing technologies.

[0039] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the conveyor belt assembly 21 completely passes through the humidification box assembly 2, allowing multiple electrode plates to be placed on the conveyor belt assembly 21. The continuous coating electrode plate humidification device in this embodiment includes an atomizing pipe 1 and a humidification box assembly 2 connected to the atomizing pipe 1. The atomizing pipe 1 includes a high-frequency atomizer 11, a positive fan 12 connected to the high-frequency atomizer 11, a negative fan 13 connected to the positive fan 12, the high-frequency atomizer 11 connected to the bottom of the humidification box assembly 2, and the negative fan 13 connected to the collection box 26 at the top of the humidification box assembly 2. The conveyor belt assembly 21 passes through the humidification box assembly 2.

[0040] like Figure 1 and Figure 2 As shown, the humidification box assembly 2 includes an isolation cover 22, and a humidification inlet 23 is provided at the bottom of the isolation cover 22. The humidification inlet 23 is connected to the high-frequency atomizer 11 through the humidification output pipe 15. A humidification perforation plate 24 is provided in the isolation cover 22, and a number of through holes are provided on the humidification perforation plate 24. The humidification perforation plate 24 is close to the humidification inlet 23.

[0041] like Figure 4 As shown, the conveyor belt assembly 21 is installed inside the isolation cover 22. The conveyor belt assembly 21 includes a perforated conveyor belt 212 and two drive rollers 211. The perforated conveyor belt 212 is sleeved on the two drive rollers 211, and the surface of the perforated conveyor belt 212 has several through holes. The perforated conveyor belt 212 is lengthened to form a structure similar to an assembly line conveyor belt, making the continuous coating electrode humidification device in this embodiment more functionally complete. The conveyor belt assembly 21 completely passes through the isolation cover 22. The isolation cover 22 has corresponding material windows 221 on its opposite side plates. The conveyor belt assembly 21 passes through two material windows 221, and there is a material conveying port 222 between it and the two material windows 221. The top of the isolation cover 22 is provided with several short recovery pipes 25, which connect the collection box 26 and the isolation cover 22. The positive fan 12 and the negative fan 13 are connected by a recovery pipe 14. The recovery pipe 14 has multiple bends to make room for the conveyor belt assembly 21, making the overall structure more compact. The top of the humidifier box assembly 2 is equipped with a temperature and humidity sensor 27, which is used to control the positive and negative fans.

[0042] The above description is a preferred embodiment of the present utility model, used to illustrate the specific structure and function of the present utility model. It should be noted that, without departing from the principle of the present utility model, those skilled in the art can make foreseeable improvements and modifications to the present utility model, and these improvements and modifications are also within the protection scope of the present utility model.
