Description

Technical Field

[0001] This disclosure relates to the field of battery drying technology, and in particular to a battery drying device and a battery cleaning machine. Background Technology

[0002] In the later stages of battery production, the surface of the battery usually needs to be cleaned and dried. For example, as disclosed in Chinese Patent Document No. CN208245323U, the battery placed in the cleaning basket can be sequentially transferred to the bubbling coarse washing tank, bubbling cleaning tank, air-draining tank, primary drying tank and secondary drying tank of the cleaning and drying mechanism to effectively remove residual electrolyte and moisture from the battery surface.

[0003] However, from the document Figure 1 It is known that the transfer of the air-cutting and dewatering tank, the primary drying tank and the secondary drying tank is performed by a robotic arm. This not only results in a complex structure, but also in a high operating frequency of the robotic arm, leading to a high frequency of damage.

[0004] Therefore, some scholars have attempted to adopt the drying technology of an automatic battery cleaning and drying device, such as the one described in Chinese patent document CN113023253B. This technology, through the combined use of a specific drying device and a conveyor belt, effectively solves the problems of complex structure and high failure rate associated with traditional robotic arm operation. However, in practical applications, because the air pipes of the specific drying device are bolted to the air pipe support via a first air pipe holder, a second air pipe holder, and a second air pipe holder, the operator must first use auxiliary tools to remove the bolts, then adjust the air pipe angle, and finally tighten the bolts to adjust the air pipe angle, resulting in a complex operation. Furthermore, the aforementioned automatic battery cleaning and drying device uses a single hot air drying method, which cannot effectively remove residual electrolyte and moisture from the battery surface. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a battery drying device and battery cleaning machine that features simple nozzle angle adjustment, high adaptability, good electrolyte and moisture removal effect, and minimal damage to the battery.

[0006] The purpose of this disclosure is achieved through the following technical solution: A battery drying device includes a conveying assembly and a hot air assembly, wherein the hot air assembly is disposed on one side of the conveying area of ​​the conveying assembly; the hot air assembly includes a first fan, a first connecting pipe and a plurality of air pipes; The first connecting pipe is connected to the first fan and has multiple staggered air outlets, each of which faces the conveying area. Each air pipe is a universal bamboo joint pipe, and each universal bamboo joint pipe includes a connected threaded connection part, a bending deformation part, and a nozzle. The threaded connection part is threadedly connected to the corresponding air outlet. The bending deformation part is used to adjust the nozzle at any angle so that each nozzle is located on the outside of the battery. The battery drying device further includes an air cutting assembly, and the hot air assembly and the air cutting assembly are arranged sequentially along the conveying area; the air cutting assembly includes a second fan, a second connecting pipe and a plurality of air knives; each air knife is arranged sequentially along the conveying area, and each air knife is connected to the second fan through the second connecting pipe.

[0007] In one embodiment, the bending and deforming section includes a plurality of sequentially connected bamboo-joint tubes, with each adjacent bamboo-joint tube being rotatably arranged relative to each other.

[0008] In one embodiment, the bending deformation portion is formed with an arc-shaped portion.

[0009] In one embodiment, the first connecting pipe includes a split pipe and a branch pipe that are connected together. The split pipe is connected to the first fan through the branch pipe, and each of the air outlets is staggered along the length of the split pipe.

[0010] In one embodiment, the nozzle is inclined in the conveying area, and the inclination direction of the nozzle is the same as the conveying direction of the conveying area.

[0011] In one embodiment, the nozzle is tilted at an angle of 35° to 55°.

[0012] In one embodiment, the nozzle is a flat nozzle.

[0013] In one embodiment, the drying temperature of the hot air assembly is 60°C to 80°C.

[0014] In one embodiment, the conveying speed of the conveying area is 20 m / min to 30 m / min.

[0015] A battery cleaning machine includes the battery drying device described in any of the above embodiments.

[0016] Compared with the prior art, this disclosure has at least the following advantages: 1) Since the first connecting pipe is connected to the first fan, the first connecting pipe has multiple staggered air outlets. Each air pipe is a universal bamboo joint pipe, and each universal bamboo joint pipe includes a connected threaded connection part, a bending deformation part, and a nozzle. The threaded connection part is threadedly connected to the corresponding air outlet, so that the operator can disassemble and assemble the universal bamboo joint pipe without the aid of auxiliary tools. Since the bending deformation part is easy for the operator to bend and shape, it is beneficial to adjust the nozzle at any angle, so that multiple nozzles are located on the outside of the battery, so as to better adapt to the drying angle of the battery required in actual production, thereby improving the adaptability of the battery drying device to batteries of different specifications. It is not only simple to operate, but also highly adaptable to batteries of different specifications.

[0017] 2) Since the hot air assembly and the air cutting assembly are arranged sequentially along the conveying area, the air cutting assembly includes a second fan, a second connecting pipe, and multiple air knives; each air knife is arranged sequentially along the conveying area, and each air knife is connected to the second fan through the second connecting pipe, so that the cleaned battery passes through the hot air assembly and the air cutting assembly in sequence. The hot air assembly can initially remove the electrolyte and moisture on the surface of the battery. At the same time, in conjunction with the multiple air knives of the air cutting assembly, the additional multiple air knives can better eliminate the electrolyte and moisture remaining on the surface of the battery, achieving a more comprehensive removal of electrolyte and moisture from the surface of the battery, while ensuring minimal damage to the battery. This effectively avoids the problem of damage to the internal structure of the battery caused by the traditional method of using hot air to dry it once, and also effectively avoids the problem of residual electrolyte and moisture on the surface of the battery caused by the traditional method of using hot air to dry it twice.

However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 3One embodiment of the battery drying device 10 includes a conveying assembly 100 and a hot air assembly 200. The hot air assembly 200 is disposed on one side of the conveying area 110 of the conveying assembly 100. The hot air assembly 200 includes a first fan 210, a first connecting pipe 220, and a plurality of air pipes. The first connecting pipe 220 is connected to the first fan 210 and has a plurality of staggered air outlets 2211, each of which faces the conveying area 110. Each air pipe is a universal bamboo joint pipe 230, and each universal bamboo joint pipe 230 includes a connected threaded connection portion 231, a bent deformation portion 232, and a nozzle 233. Please refer to the attached document. Figure 4 The threaded connection 231 is threadedly connected to the corresponding air outlet 2211; the bending deformation part 232 is used to adjust the arbitrary angle of the nozzle 233 so that each nozzle 233 is located on the outside of the battery; the battery drying device 10 also includes an air cutting assembly 300, the hot air assembly 200 and the air cutting assembly 300 are arranged sequentially along the conveying area 110; the air cutting assembly 300 includes a second fan 310, a second connecting pipe and a plurality of air knives 320; each air knife 320 is arranged sequentially along the conveying area 110, and each air knife 320 is connected to the second fan 310 through the second connecting pipe.

[0025] It is understood that, since the first connecting pipe 220 is connected to the first fan 210, the first connecting pipe 220 has multiple staggered air outlets 2211. Each air pipe is a universal bamboo joint pipe 230. Each universal bamboo joint pipe 230 includes a connected threaded connection part 231, a bending deformation part 232, and a nozzle 233. The threaded connection part 231 is threadedly connected to the corresponding air outlet 2211, so that the operator can disassemble and assemble the universal bamboo joint pipe 230 without the aid of auxiliary tools. Since the bending deformation part 232 is easy for the operator to bend and shape, it is beneficial to adjust the arbitrary angle of the nozzle 233, so that multiple nozzles 233 are located on the outside of the battery, so as to better adapt to the drying angle of the battery required in actual production, thereby improving the adaptability of the battery drying device 10 to batteries of different specifications. It is not only simple to operate, but also highly adaptable to batteries of different specifications.

[0026] It should be noted that the traditional air drying methods are generally either single-stage hot air drying or double-stage hot air drying. Single-stage hot air drying usually has a relatively high temperature, which can easily damage the internal structure of the battery. Although double-stage hot air drying solves the problem of damage to the internal structure of the battery caused by the high temperature of single-stage hot air drying to some extent, double-stage hot air drying cannot achieve a more comprehensive removal of electrolyte and moisture remaining on the battery surface. Therefore, in this application, since the hot air assembly 200 and the air cutting assembly 300 are sequentially arranged along the conveying area 110, the air cutting assembly 300 includes a second fan 310, a second connecting pipe, and multiple air knives 320; each air knife 320 is sequentially arranged along the conveying area 110, and each air knife 320 is connected to the second fan 310 through the second connecting pipe, so that the cleaned battery passes through the hot air assembly 200 and the air cutting assembly 300 in sequence. The hot air assembly 200 can initially remove the electrolyte and moisture on the surface of the battery. At the same time, in conjunction with the multiple air knives 320 of the air cutting assembly 300, the additional multiple air knives 320 can better eliminate the electrolyte and moisture remaining on the surface of the battery, achieving a more comprehensive removal of electrolyte and moisture from the surface of the battery, while ensuring minimal damage to the battery. This effectively avoids the problem of damage to the internal structure of the battery caused by the traditional method of using hot air to dry, and also effectively avoids the problem of residual electrolyte and moisture on the surface of the battery caused by the traditional method of using hot air to dry.

[0027] Before operation, the operator bends and shapes each of the universal bamboo-joint tubes 230 according to the actual battery being produced, adjusting the multiple nozzles 233 of the multiple universal bamboo-joint tubes 230 to the outside of the battery, so that the multiple nozzles 233 are located on the outside of the battery, so as to well adapt to the drying angle of the battery required for actual production; during operation, when the cleaned battery is conveyed by the conveying assembly 100 to the area below the hot air assembly 200, the first fan 210 is started, so that the first fan 210 can draw hot air to the first connecting pipe 220. The first connecting pipe 220 then diverts the fluid to multiple universal bamboo-joint pipes 230, allowing the multiple universal bamboo-joint pipes 230 to more thoroughly remove residual electrolyte and moisture from the battery surface. Next, the second fan 310 is started, allowing the second fan 310 to draw air to the second connecting pipe, and then divert the air to multiple air knives 320, so that the flow rate of the multiple air knives 320 can effectively eliminate the electrolyte and moisture remaining on the battery surface, achieving more comprehensive removal of electrolyte and moisture from the battery surface, while ensuring minimal damage to the battery.

[0028] like Figure 4 As shown, in one embodiment, the bending deformation section 232 includes a plurality of sequentially connected bamboo joint tubes 2321, with each adjacent bamboo joint tube 2321 being rotatably arranged to achieve bending and shaping of the bending deformation section 232.

[0029] It should be noted that the connection structure of the multiple sequentially connected bamboo-joint sub-tubes 2321 of the universal bamboo-joint tube 230, the specific structure of the air knife 320, and the connection structure between the multiple air knives 320 and the second connecting tube are all prior art. Those skilled in the art can obtain them through existing technical solutions, such as the structure of the universal bamboo-joint tube 230 in Chinese Patent Document No. CN205896461U and the structure of the air knife 320 in Chinese Patent Document No. CN115679236A. Therefore, specific descriptions are not provided in this application.

[0030] like Figure 4 As shown, in one embodiment, the bending deformation portion 232 is formed with an arc-shaped portion 2322 to ensure that the universal bamboo tube 230 is in a suitable setting position in the delivery area 110, thereby effectively removing residual electrolyte and moisture from the battery surface.

[0031] In one embodiment, the universal bamboo tube 230 is a plastic universal bamboo tube 230. Since the plastic universal bamboo tube 230 has better elasticity than the metal universal bamboo tube 230, it is easier for the operator to quickly bend and shape it, and the cost is lower.

[0032] In this embodiment, the material of the plastic universal bamboo joint tube 230 is prior art. Those skilled in the art can select the corresponding plastic material according to actual production needs, such as thermoplastic polyurethane or polyvinyl chloride. Therefore, the material of the plastic universal bamboo joint tube 230 is not within the scope of protection of this application. This application only protects the connection relationship and positional relationship between the plastic universal bamboo joint tube 230 and the first connecting tube 220.

[0033] like Figure 3 As shown, in one embodiment, the first connecting pipe 220 includes a connected branch pipe 221 and a branch pipe 222. The branch pipe 221 is connected to the first fan 210 through the branch pipe 222 to realize the connection between the first fan 210 and the first connecting pipe 220. Since each of the air outlets 2211 is staggered along the length of the branch pipe 221, multiple air outlets 2211 are staggered in the branch pipe 221.

[0034] In one embodiment, each of the air outlets 2211 is equidistantly distributed along the length of the diversion pipe 221 to ensure that the multiple universal bamboo joint pipes 230 are evenly distributed along the conveying area 110. This ensures that the airflow of the multiple universal bamboo joint pipes 230 after bending and shaping is more uniform, so that the multiple universal bamboo joint pipes 230 can more comprehensively remove the residual electrolyte and moisture on the battery surface. This effectively avoids the inability to remove the residual electrolyte and moisture on the battery surface due to the weak or strong airflow of individual universal bamboo joint pipes 230.

[0035] In one embodiment, the nozzle 233 is inclined in the conveying area 110 to ensure that the hot air from the nozzle 233 can thoroughly remove residual electrolyte and moisture from the battery surface. Since the inclination direction of the nozzle 233 is the same as the conveying direction of the conveying area 110, the hot air from the nozzle 233 will not interfere with the normal conveying of the battery, thus ensuring that the friction of the airflow from the nozzle 233 on the battery is small, effectively reducing the probability of damage to the battery surface when the hot air assembly 200 dries the battery.

[0036] In one embodiment, the tilt angle of the nozzle 233 is 35°~55° to ensure that the angle of the hot air coming out of the nozzle 233 is more suitable. Under the premise of ensuring that the friction of the air force of the nozzle 233 on the battery is small, it also ensures that the hot air coming out of the nozzle 233 can more thoroughly remove the residual electrolyte and moisture on the battery surface.

[0037] In one embodiment, the nozzle 233 is a flat nozzle to ensure that the single hot air sweeping area of ​​the flat nozzle is large, effectively avoiding the problem of a large frictional force on the battery caused by a concentrated single hot air sweeping area.

[0038] In one embodiment, the drying temperature of the hot air assembly 200 is 60°C to 80°C to ensure that the drying temperature of the hot air assembly 200 is suitable. This effectively avoids the situation where the drying temperature of the hot air assembly 200 is too low and cannot remove the residual electrolyte and moisture on the battery surface, while also effectively avoiding the situation where the drying temperature of the hot air assembly 200 is too high and damages the internal structure of the battery.

[0039] In one embodiment, the conveying speed of the conveying area 110 is 20 m / min to 30 m / min to ensure that the conveying speed of the battery drying device 10 is suitable. In particular, the wind speed of the first fan 210 is 2800 to 3600 r / min to ensure that the battery is conveyed at a suitable speed in the hot air assembly 200. In this way, while satisfying the requirement of thoroughly removing residual electrolyte and moisture from the battery surface, a high drying efficiency is also guaranteed, and the probability of damage to the battery surface is effectively reduced.

[0040] like Figure 1As shown, this application also provides a battery cleaning machine 1, including the battery drying device 10 described in any of the above embodiments. It includes a cleaning component 20, which is disposed on the side of the hot air component 200 away from the air cutting component 300. That is, the cleaning component 20, hot air component 200, and air cutting component 300 are sequentially arranged along the conveying area 110 to ensure that the cleaned batteries are sequentially conveyed to the hot air component 200 and air cutting component 300 via the conveying component 100, thereby completing the automatic cleaning and drying operation of the batteries. When changing batteries of different specifications, the operator can bend and shape each universal bamboo joint tube 230 to adjust each nozzle 233 of the universal bamboo joint tube 230 to the outside of the battery, thereby ensuring that multiple nozzles 233 can more comprehensively remove residual electrolyte and moisture from the battery surface. This is not only simple and fast to operate, but also highly adaptable to different battery specifications.

[0041] Compared with the prior art, this disclosure has at least the following advantages: 1) Since the first connecting pipe 220 is connected to the first fan 210, the first connecting pipe 220 has multiple staggered air outlets 2211. Each air pipe is a universal bamboo joint pipe 230. Each universal bamboo joint pipe 230 includes a connected threaded connection part 231, a bending deformation part 232, and a nozzle 233. The threaded connection part 231 is threadedly connected to the corresponding air outlet 2211, so that the operator can disassemble and assemble the universal bamboo joint pipe 230 without the aid of auxiliary tools. Since the bending deformation part 232 is easy for the operator to bend and shape, it is beneficial to adjust the arbitrary angle of the nozzle 233, so that multiple nozzles 233 are located on the outside of the battery, so as to better adapt to the drying angle of the battery required in actual production, thereby improving the adaptability of the battery drying device 10 to batteries of different specifications. It is not only simple to operate, but also highly adaptable to batteries of different specifications.

[0042] 2) Since the hot air assembly 200 and the air cutting assembly 300 are arranged sequentially along the conveying area 110, the air cutting assembly 300 includes a second fan 310, a second connecting pipe, and multiple air knives 320; each air knife 320 is arranged sequentially along the conveying area 110, and each air knife 320 is connected to the second fan 310 through the second connecting pipe, so that the cleaned battery passes through the hot air assembly 200 and the air cutting assembly 300 in sequence. The hot air assembly 200 can initially remove the electrolyte and moisture on the surface of the battery. At the same time, in conjunction with the multiple air knives 320 of the air cutting assembly 300, the additional multiple air knives 320 can better eliminate the electrolyte and moisture remaining on the surface of the battery, achieving a more comprehensive removal of electrolyte and moisture from the surface of the battery, while ensuring minimal damage to the battery. This effectively avoids the problem of damage to the internal structure of the battery caused by the traditional method of using hot air to dry it once, and also effectively avoids the problem of residual electrolyte and moisture on the surface of the battery caused by the traditional method of using hot air to dry it twice.

[0043] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
