Description

Technical Field

[0001] The present invention relates to the technical field of cleaning and drying devices, and in particular to a battery aluminum shell cleaning and drying device. Background Art

[0002] Battery aluminum casings are key structural components widely used in various types of rechargeable lithium-ion batteries. They are primarily formed by stamping or stretching aluminum alloys with excellent properties. Their core function is to provide a sturdy, airtight, and lightweight physical container for the internal battery cells, effectively isolating them from external environmental contamination, moisture erosion, and physical shock, thereby ensuring the stable and safe operation of the battery's internal chemical reactions. The aluminum casing's excellent conductivity enables it to serve directly as the battery's negative electrode current collector or be tightly connected to the negative electrode tab, forming an efficient current conduction channel. Its excellent thermal conductivity also helps dissipate heat generated during the battery's charge and discharge processes to the external environment, making it crucial for the battery's thermal management and safety performance.

[0003] Furthermore, aluminum's inherent low density significantly reduces the overall weight of the battery, which is particularly critical for applications seeking high energy density and lightweight construction. Its excellent mechanical strength and ductility also ensure that the housing can withstand certain internal and external pressures during the manufacturing process and subsequent use, maintaining structural integrity. Therefore, battery aluminum housings, with their combined advantages of sealing, electrical and thermal conductivity, lightweight construction, and structural strength, have become an indispensable component of modern high-performance lithium-ion batteries, widely used in new energy vehicle power batteries, energy storage system batteries, and high-end consumer electronics batteries.

DETAILED DESCRIPTION

[0036] Exemplary embodiments of the present application will be described in detail with reference to the drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0037] As Figs. 1 to 3 shown, the embodiment of the present application provides a battery aluminum shell cleaning and drying device, which comprises a cleaning base 1, a rotating spray head 2, a spherical nozzle 3, and a conveying member.

[0038] Specifically, the rotating spray head 2 is fixedly installed on the cleaning base 1, the input end of the rotating spray head 2 is connected with a water source and an air source, and the rotating spray head 2 switches the water source and the air source through a control valve.

[0039] The spherical nozzle 3 is fixedly installed on the top of the rotating spray head 2, and the spherical nozzle 3 is in communication with the flow channel of the rotating spray head 2, and the spherical nozzle 3 is used for circumferential washing of the top of the battery aluminum shell 16.

[0040] The conveying member is fixedly installed on the cleaning base 1, and the conveying member is located on the upper part of the rotating spray head 2, and the conveying member is used for conveying the battery aluminum shell 16.

[0041] In the embodiment, when the battery aluminum shell 16 needs to be cleaned, the conveying member adsorbs and fixes the battery aluminum shell 16 to be cleaned and conveys the battery aluminum shell 16 to the cleaning base 1, and the battery aluminum shell 16 is located outside the rotary spray head 2. Then, the high-pressure water source connected with the rotary spray head 2 is communicated, the rotary spray head 2 rotates and sprays the cleaning liquid, and the cleaning liquid can flush the inner side wall of the battery aluminum shell 16. At the same time, the rotary nozzle at the top of the rotary spray head 2 flushes the top surface and the top side wall of the battery aluminum shell 16. The two cooperate to fully and comprehensively clean the inner wall of the battery aluminum shell 16, thereby improving the cleaning quality of the battery aluminum shell 16. Subsequently, the high-pressure water source is closed, the rotary spray head 2 is connected with the gas source, and the airflow drives the rotary spray head 2 to rotate and dry the inner wall of the battery aluminum shell 16. In order to improve the drying efficiency, a hot gas source can be used to dry the inner wall of the battery aluminum shell 16. Finally, after the battery aluminum shell 16 is dried, the conveying member conveys the battery aluminum shell 16 to the designated storage area, and the cleaning and drying operation of the single battery aluminum shell 16 is completed. The above operation is repeated to realize the continuous cleaning and drying operation of the battery aluminum shell 16.

[0042] In a specific embodiment, the upper surface of the cleaning base 1 is provided with a drainage groove 4, which is arranged in an inclined manner and is used to collect the cleaning liquid of the battery aluminum shell 16. During the cleaning of the battery aluminum shell 16, the cleaning liquid flows along the drainage groove 4 to the bottom position, facilitating the rapid discharge of the cleaning liquid.

[0043] In addition, the input end of the rotary spray head is provided with a three-way electromagnetic valve (not shown in the figure), which is connected with the rotary spray head, the air pressure pump and the water source, respectively.

[0044] When the inner wall of the battery aluminum shell 16 needs to be cleaned, the three ports of the three-way electromagnetic valve are opened, the air pressure pump sends high-pressure gas into the three-way electromagnetic valve, and the water source sends cleaning liquid into the three-way electromagnetic valve. Under the action of the high-pressure gas flow of the air pressure pump, the cleaning liquid is sprayed from the rotary spray head 2 and the spherical nozzle 3 to fully and comprehensively clean the inner wall of the battery aluminum shell 16, thereby greatly improving the cleaning quality of the battery aluminum shell 16.

[0045] When the battery aluminum shell 16 needs to be dried, the water source port of the three-way electromagnetic valve is closed, the air pressure pump sends high-pressure gas into the three-way electromagnetic valve, and the high-pressure gas flows through the rotary spray head 2 and the spherical nozzle 3 to dry the inner wall of the battery aluminum shell, thereby quickly realizing the drying of the battery aluminum shell 16.

[0046] Ultrasonic cleaning differs from ultrasonic cleaning, which requires placing the battery aluminum shell 16 in a cleaning solution and using the high-frequency vibrations of ultrasound to clean it. However, the battery aluminum shell 16 is open at one end, and when the battery aluminum shell 16 is in the cleaning solution, there is a certain amount of air pressure inside it, which may prevent the cleaning solution from fully contacting the battery aluminum shell 16, resulting in inadequate cleaning.

[0047] However, this solution adopts suspended cleaning, and the cleaning liquid can fully clean the inner wall of the battery aluminum shell 16, which greatly improves the cleaning quality of the battery aluminum shell.

[0048] Furthermore, the spherical nozzle 3 includes a connecting portion 5 and a spherical spray chamber 6. The connecting portion 5 is fixedly connected to the rotating spray head 2 and communicates with the flow path of the rotating spray head 2. The spherical spray chamber 6 is fixedly mounted on the connecting portion 5 and communicates with the connecting portion 5. The spherical spray chamber 6 is evenly provided with a plurality of spray holes 7, and the spray holes 7 are radially arranged on the spherical spray chamber 6.

[0049] In this embodiment, the rotary nozzle 2 can only perform horizontal cleaning operations and cannot fully clean the top surface of the battery aluminum shell. In order to compensate for the blind spots of the rotary nozzle 2, a rotary nozzle 3 is installed at the top of the rotary nozzle 2. The rotary nozzle 3 has spray holes 7 arranged in the radial direction. During the cleaning process of the cleaning liquid spraying, the top surface of the battery aluminum shell can be fully cleaned, thereby greatly improving the cleaning quality of the battery aluminum shell 16.

[0050] Furthermore, the conveying member includes a mounting frame 8 , a displacement driving member, a lifting cylinder 9 and a fixed suction cup 10 .

[0051] Specifically, the mounting bracket 8 is fixedly mounted on the cleaning base 1 .

[0052] The displacement driving member is mounted on the mounting frame 8 , and is used to drive the lifting cylinder 9 and the fixed suction cup 10 to perform linear motion.

[0053] The lifting cylinder 9 is fixedly mounted on the displacement driving member, and the lifting cylinder 9 is used to drive the fixed suction cup 10 to perform lifting motion.

[0054] The fixed suction cup 10 is fixedly installed on the output end of the lifting cylinder 9, and the fixed suction cup 10 adsorbs and fixes the battery aluminum shell 16 through negative pressure.

[0055] In the embodiment, the displacement driving member comprises a moving guide rail 11, a mounting table 12, an adjusting screw rod 13 and a driving motor 14. The moving guide rail 11 is fixedly installed on the mounting frame 8. The mounting table 12 is slidingly installed on the moving guide rail 11, and the lifting cylinder 9 is fixedly installed on the mounting table 12. The adjusting screw rod 13 is rotatably installed on the moving guide rail 11, and the adjusting screw rod 13 is threadedly connected with the mounting table 12. The driving motor 14 is fixedly installed on the moving guide rail 11, and the driving motor 14 is drivingly connected with the adjusting screw rod 13.

[0056] When the battery aluminum shell 16 needs to be conveyed, first, the fixed suction cup 10 is lowered by the lifting cylinder 9, and the bottom surface of the battery aluminum shell 16 is adsorbed and fixed by the fixed suction cup 10. Then, the driving motor 14 is turned on, and under the driving of the driving motor 14, the adjusting screw rod 13 rotates. The mounting table 12 threadedly connected with the adjusting screw rod 13 cannot rotate with the adjusting screw rod 13 due to the limitation of the mounting table 12, and can only move along the length direction of the adjusting screw rod 13. When the battery aluminum shell 16 moves above the rotating spray head 2, the lifting cylinder 9 lowers the battery aluminum shell 16, so that the battery aluminum shell 16 is sleeved outside the rotating spray head 2. At this time, the inner wall of the battery aluminum shell 16 can be cleaned and dried. Finally, after the cleaning and drying operation of the battery aluminum shell 16 is completed, the lifting cylinder 9 lifts the battery aluminum shell 16, and the displacement driving member conveys the battery aluminum shell 16 to the designated storage area, and the cleaning and drying operation of the single battery aluminum shell 16 is completed.

[0057] In a specific embodiment, the driving motor 14 and the adjusting screw rod 13 are drivingly connected through the worm gear 15. By using the self-locking action of the worm gear 15, the battery aluminum shell 16 can be stably kept at the current position when the driving motor 14 stops working, so as to realize the stable cleaning and drying operation of the battery aluminum shell 16.

[0058] In addition, the driving motor 14 is a servo motor. The servo motor refers to a motor for controlling the operation of a mechanical element in a servo system, and is an auxiliary motor indirect speed changing device. The servo motor can control the speed and the position accuracy is very accurate, and can convert the voltage signal into torque and speed to drive the control object. The servo motor rotor speed is controlled by the input signal and can quickly react. In an automatic control system, the servo motor is used as an execution element, and has the characteristics of small electromechanical time constant and high linearity, and can convert the received electric signal into angular displacement or angular velocity output on the motor shaft.

[0059] The driving motor 14 adopts a servo motor, can accurately control the rotating speed and angular displacement of the driving motor 14, and can accurately set the battery aluminum shell 16 to be cleaned outside the rotating nozzle 2, so as to realize accurate cleaning and drying of the battery aluminum shell 16.

[0062] The above is the preferred embodiment of the present application, it should be pointed out that, for the ordinary skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
