Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a cleaning device for the bottom of a flower basket and an automated loading and unloading machine. Background Technology

[0002] In the later stages of battery production, dried flower baskets are the primary carriers for transporting battery cells. However, they easily absorb dust and dirt, significantly increasing the risk of cell contamination. On one hand, if the slots in direct contact with the cells are not thoroughly cleaned, they can directly contaminate the cell surface. On the other hand, dust or dirt at the bottom of the baskets can not only contaminate other baskets via the conveyor belt but may also splash onto the cell surface during automated transfer in the front and back film processes, causing quality defects such as pitting. Currently, the dried flower basket wiping machine used in the workshop can only clean the slots; the bottom of the baskets has long lacked effective cleaning methods, resulting in persistent conveyor belt contamination and potential quality issues with the cells.

[0006] In one possible implementation, the cylinder comprises: A cylindrical wall extends along the rotation axis of the rotating component, and the wall surface of the cylindrical wall is a polygonal mesh surface; Two end walls are respectively connected to the opposite ends of the cylindrical wall and together with the cylindrical wall to form a hollow structure. Both end walls are provided with clearance holes for the fixed shaft to pass through.

[0007] In one possible implementation, the liquid nozzle includes a nozzle housing fixed to the fixed shaft, the nozzle housing having a plurality of spray nozzles arranged along the extension direction of the fixed shaft.

[0008] In one possible implementation, the fixed shaft is further provided with an air knife assembly, the air outlet of which faces the top of the gap between two adjacent conveyor belts, and the air outlet blows air towards the bottom of the flower basket being conveyed by the conveyor belt through the hollowed-out rotating surface.

[0010] In one possible implementation, the first mounting plate and the second mounting plate are each provided with mounting bushings corresponding to the first winding member and the second winding member, and the two ends of the first winding member and the two ends of the second winding member are rotatably assembled between the first mounting plate and the second mounting plate through the mounting bushings.

[0011] In one possible implementation, the cleaning device at the bottom of the flower basket further includes a wastewater tank located below the first winding member, the second winding member, and the rotating member.

[0012] In one possible implementation, the drive assembly includes a first motor and a second motor, the output of the first motor being connected to the first winding member, and the output of the second motor being connected to the second winding member.

[0013] This application also discloses an automated loading and unloading machine, including a basket loading unit, a battery cell transport unit and a basket unloading unit arranged in sequence. The basket loading unit includes a cleaning device for the bottom of the basket and multiple conveyor belts. The cleaning device for the bottom of the basket is disposed in the gap between adjacent conveyor belts. The cleaning device for the bottom of the basket is any of the cleaning devices for the bottom of the basket described above.

[0014] Compared with the prior art, the beneficial effects of this application are as follows: In the cleaning device and automated loading / unloading machine for the bottom of the flower basket provided in this application, the bracket is the basic support component of the entire cleaning device.

At the same time, the drive component can adjust the winding speed of the cleaning cloth according to actual production needs, ensuring efficient cleaning of the bottom of the flower basket during continuous production, improving production efficiency and reducing the frequency of manual cloth replacement. The overall structure of the device is simple, installed in the gap between two adjacent conveyor belts, has good compatibility with existing production equipment, and does not occupy too much extra space.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0022] In the later stages of battery production, dried flower baskets are the primary carriers for transporting battery cells. However, they easily absorb dust and dirt, significantly increasing the risk of cell contamination. On one hand, if the slots in direct contact with the cells are not thoroughly cleaned, they can directly contaminate the cell surface. On the other hand, dust or dirt at the bottom of the baskets can not only contaminate other baskets via the conveyor belt but may also splash onto the cell surface during automated transfer in the front and back film processes, causing quality defects such as pitting. Currently, the dried flower basket wiping machine used in the workshop can only clean the slots; the bottom of the baskets has long lacked effective cleaning methods, resulting in persistent conveyor belt contamination and potential quality issues with the cells.

[0023] In view of this, some embodiments of this application provide a cleaning device for the bottom of a flower basket and an automated loading and unloading machine. The first end of the cleaning cloth is wound around a first winding member, and the second end of the cleaning cloth is wound around a second winding member. The portion of the cleaning cloth between the first and second ends passes through a rotating member and is wound around the outside of the rotating member to contact the bottom of the flower basket being conveyed by the conveyor belt. This can clean the bottom of the flower basket, effectively solving the problem that the bottom of the flower basket is dirty and easily contaminates the conveyor belt and battery cells, improving the cleaning process of dried flower baskets and improving the overall quality of battery cell production.

[0024] The present application will be described in detail below through specific embodiments: The cleaning device at the bottom of the flower basket in this embodiment of the application, such as... Figures 1 to 5 As shown, a cleaning device for the bottom of a flower basket is used to be installed in the gap between two adjacent conveyor belts 80. The conveyor belts 80 are used to transport the flower basket 90. The cleaning device includes a bracket 10, a first winding member 20 and a second winding member 30. The first winding member 20 is rotatably mounted on the bracket 10, and the second winding member 30 is rotatably mounted on the bracket 10. The second winding member 30 is spaced apart from the first winding member 20 and arranged parallel to it.

[0025] like Figure 3 As shown, the cleaning device also includes a rotating component 40, which is rotatably mounted on the bracket 10. The rotating component 40 is parallel to the first winding component 20, and the rotation axis of the rotating component 40 is perpendicular to the conveying direction of the conveyor belt 80. The height of the top of the rotating component 40 matches the height of the conveying surface of the conveyor belt 80.

[0026] like Figure 3 As shown, the cleaning device also includes a cleaning cloth 50. The first end 51 of the cleaning cloth 50 is wound around the first winding member 20, and the second end 52 of the cleaning cloth 50 is wound around the second winding member 30. The portion of the cleaning cloth 50 between the first end 51 and the second end 52 passes through the rotating member 40 and is wound around the outside of the rotating member 40 to contact the bottom 91 of the flower basket conveyed by the conveyor belt 80.

[0027] like Figure 3 As shown, the cleaning device also includes a drive assembly 60, which can drive the first winding member 20 and the second winding member 30 to rotate synchronously, so that the cleaning cloth 50 is wound from the first winding member 20 to the second winding member 30, and the portion of the cleaning cloth 50 wound on the outside of the rotating member 40 is used to clean the bottom of the flower basket.

[0028] In the cleaning device for the bottom of the flower basket provided in this embodiment, the support frame 10 is the basic support component of the entire cleaning device. The first winding member 20 and the second winding member 30 are arranged parallel to each other and spaced apart on the support frame 10, forming a winding system for the cleaning cloth 50. The first winding member 20 is used to store unused cleaning cloths 50, and the second winding member 30 is used to recycle used cleaning cloths 50. Through the cooperation of the two, the cleaning cloth 50 can be continuously supplied and replaced, ensuring that the cleaning work can be carried out continuously. Further, the rotating member 40 is rotatably mounted on the support frame 10, and its rotation axis is perpendicular to the conveying direction of the conveyor belt 80. The height of the top end matches the height of the conveying surface of the conveyor belt 80. The portion of the cleaning cloth 50 between its two ends passes through the rotating member 40 and is wrapped around its outer side. When the flower basket 90 passes through the cleaning device with the conveyor belt 80, the cleaning cloth 50 on the outer side of the rotating member 40 can fully contact the bottom of the flower basket 90, and the bottom of the flower basket 90 is wiped and cleaned by the movement of the cleaning cloth 50. The drive assembly 60 provides power for the winding of the cleaning cloth 50 and can adjust the winding speed of the cleaning cloth 50 to match the conveying speed of the conveyor belt 80. This ensures that when cleaning the bottom of the flower basket, the cleaning cloth 50 can effectively remove dirt without affecting the cleaning effect or wasting the cleaning cloth 50 due to excessively fast or slow speed.

[0029] Therefore, this device effectively solves the problem of dirt on the bottom of the flower basket 90 easily contaminating the conveyor belt and battery cells by placing the cleaning cloth 50 in the gap between two adjacent conveyor belts 80, thus improving the cleaning process of dried flower baskets and enhancing the overall quality of battery cell production. The cleaning cloth 50 is continuously wound from the first winding member 20 to the second winding member 30, allowing the cleaning cloth 50 to continuously refresh the cleaning surface in contact with the bottom of the flower basket 90, preventing the cleaning cloth 50 from becoming dirty due to repeated use and reducing its cleaning effect. Simultaneously, the drive component 60 can adjust the winding speed of the cleaning cloth 50 according to actual production needs, ensuring efficient cleaning of the bottom of the flower basket 90 throughout continuous production, improving production efficiency and reducing the frequency of manual cleaning cloth 50 replacement. The device has a simple overall structure, is installed in the gap between two adjacent conveyor belts 80, has good compatibility with existing production equipment, and does not occupy excessive additional space.

[0030] In the diagram, the X direction is the conveying direction of the conveyor belt 80, the Y direction is the conveying direction perpendicular to the conveyor belt 80, and the Z direction is the extension direction of the fixed shaft 11.

[0031] In one possible implementation, such as Figure 1 and Figure 2 As shown, the bracket 10 includes a fixed shaft 11, which extends along the rotation axis of the rotating member 40.

[0032] like Figure 1 and Figure 2As shown, the bracket 10 also includes a first mounting plate 12 and a second mounting plate 13. The first mounting plate 12 and the second mounting plate 13 are arranged opposite each other along the rotation axis of the rotating member 40. The first winding member 20 and the second winding member 30 are both rotatably assembled between the first mounting plate 12 and the second mounting plate 13.

[0033] like Figure 5 As shown, the rotating component 40 includes a cylindrical body 41, which has a hollow structure and a hollow rotating surface 41a. The fixed shaft 11 is rotatably assembled with the cylindrical body 41. like Figure 4 As shown, the rotating component 40 also includes a liquid nozzle 42, which is disposed inside the cylinder 41. The liquid nozzle 42 sprays liquid toward the cleaning cloth 50 through the hollowed-out rotating surface 41a.

[0034] In this embodiment, as Figure 1 and Figure 2 As shown, the bracket 10 also includes two legs 14 arranged opposite each other along the rotation axis of the rotating member 40. The two ends of the fixed shaft 11 are respectively fixed on the two legs 14, and the first mounting plate 12 and the second mounting plate 13 are respectively fixed on the two legs 14.

[0035] The bracket 10 includes a fixed shaft 11, a first mounting plate 12, and a second mounting plate 13. The first mounting plate 12 and the second mounting plate 13 are used to assemble the first winding component 20 and the second winding component 30, and the fixed shaft 11 is used to assemble the rotating component 40, forming a stable support system. The fixed shaft 11 extends along the rotation axis of the rotating component 40, providing a rotation axis for the rotating component 40, ensuring that the rotating component 40 maintains axial stability during operation and reducing swaying and offset. The first mounting plate 12 and the second mounting plate 13 are arranged opposite to each other to form a clamp-type fixing structure, clamping the first winding component 20 and the second winding component 30 between them, so that the winding components can rotate flexibly while maintaining precise axial positioning, ensuring the smoothness and synchronization of the winding process of the cleaning cloth 50.

[0036] Furthermore, the cylinder 41 of the rotating component 40 features a hollow, perforated rotating surface design, which reduces the overall weight of the device while maximizing the liquid spray channel. The cylinder 41 is rotatably assembled with the fixed shaft 11, and its rotation angle can adaptively adjust according to the contact pressure at the bottom of the basket 90, ensuring that the cleaning cloth 50 and the bottom of the basket 90 always maintain a tight fit. The liquid nozzle 42 is built into the cylinder 41, and the perforated rotating surface can evenly disperse the cleaning liquid sprayed by the liquid nozzle 42 onto the surface of the cleaning cloth 50, forming a continuous and uniform wetted area, providing a basic condition for efficient cleaning.

[0037] Therefore, through a combined cleaning mode of liquid immersion and dynamic wiping, the cleaning cloth 50 softens stubborn stains upon contact with the bottom of the flower basket 90 using the dissolving effect of the cleaning liquid, and then thoroughly removes the stains through physical wiping. The combination of the fixed shaft 11 and the mounting plate improves the vibration resistance and structural rigidity of the bracket 10, maintains the relative position stability of each component, and reduces malfunctions such as the cleaning cloth 50 shifting or the nozzle clogging caused by vibration.

[0038] In some embodiments, such as Figure 5 As shown, the cylinder 41 includes a cylindrical wall 411, which extends along the rotation axis of the rotating member 40, and the wall surface of the cylindrical wall 411 is a polygonal mesh surface.

[0039] like Figure 5 As shown, the cylinder 41 also includes two end walls 412, which are respectively connected to the opposite ends of the cylindrical wall 411 and together with the cylindrical wall 411 form a hollow structure. Both end walls 412 are provided with clearance holes for the fixed shaft 11 to pass through.

[0040] The cylindrical wall 411 extends along the rotation axis of the rotating component 40, and its surface features a polygonal mesh design. On one hand, the polygonal mesh forms regular perforated channels, ensuring that the cleaning liquid, such as alcohol, sprayed from the liquid nozzle 42 passes evenly and unobstructed through the cylinder wall, precisely acting on the surface of the cleaning cloth 50. On the other hand, while maintaining structural strength, the polygonal mesh increases the contact area between the cylinder wall and the cleaning cloth 50, helping the cleaning cloth 50 to better adhere to the cylinder wall, thereby improving the uniformity of the cleaning liquid distribution on the cleaning cloth 50. Furthermore, the edges of the polygonal mesh can also provide a certain scraping effect during the movement of the cleaning cloth 50, assisting in removing larger particles of dirt adhering to the surface and further optimizing the cleaning effect.

[0041] Two end walls 412 are respectively connected to the opposite ends of the cylindrical wall 411, forming a hollow structure together with the cylindrical wall 411, providing installation space for internal components such as the liquid nozzle 42. The clearance holes provided on the end walls 412 are precisely matched to the fixed shaft 11, allowing the fixed shaft 11 to pass smoothly through them. This not only ensures that the cylinder 41 can rotate flexibly around the fixed shaft 11 and achieve adaptive adjustment of the contact pressure with the bottom of the basket 90, but also enhances the overall structural rigidity of the cylinder 41 through the stable connection between the end walls 412 and the cylindrical wall 411, ensuring that the cylinder 41 will not deform or shake during the cleaning process, maintaining the stability of the contact between the cleaning cloth 50 and the bottom of the basket 90 and the consistency of the cleaning effect.

[0042] In other embodiments, the wall surface of the cylindrical wall 411 may also be a circular hole or an irregular perforation, which is not limited here.

[0043] like Figure 2 and Figure 4 As shown, the liquid nozzle 42 includes a nozzle housing 421, which is fixed to a fixed shaft 11. The nozzle housing 421 is provided with a plurality of spray nozzles 422 arranged along the extension direction of the fixed shaft 11.

[0044] Multiple spray nozzles 422 arranged along the extension direction of the fixed axis 11 enable the cleaning liquid to be sprayed evenly onto the cleaning cloth 50, forming a uniform wet layer. When the cleaning cloth 50 comes into contact with the bottom of the flower basket 90, the evenly wetted cleaning cloth 50 can more effectively dissolve and absorb stains, ensuring thorough cleaning of both the central area and the edges of the bottom of the flower basket 90.

[0045] The structure of the nozzle housing 421 fixed to the fixed shaft 11 improves the installation stability of the nozzle. During long-term continuous operation of the cleaning device, the nozzle will not loosen due to vibration or pulling of the cleaning cloth 50, reducing the probability of abnormal cleaning fluid spraying caused by nozzle displacement. The stable installation also makes nozzle maintenance more convenient. Operators can directly inspect, clean, or replace the nozzle through the fixed shaft 11 without the need for large-scale disassembly of the entire cleaning device, reducing the difficulty and cost of equipment maintenance and improving the reliability and operating efficiency of the equipment.

[0046] Specifically, such as Figure 4 As shown, the nozzle housing 421 is partially housed inside the fixed shaft 11 and is used to hold cleaning fluids such as alcohol. The spray nozzle 422 protrudes from the fixed shaft 11. A miniature air pump or a compressed air pipeline can be connected to the outside of the nozzle housing 421 to compress the alcohol inside the housing and spray it out from the spray nozzle 422. Alternatively, hydraulic components such as pistons, gear pumps, or peristaltic pumps can be used to mechanically compress the alcohol and discharge it from the spray nozzle 422. This application does not impose any limitations.

[0047] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, the fixed shaft 11 is also provided with an air knife assembly 43. The air outlet 431 of the air knife assembly 43 faces the top of the gap between two adjacent conveyor belts 80. The air outlet 431 blows air towards the bottom 91 of the flower basket conveyed by the conveyor belt 80 through the hollowed-out rotating surface 41a.

[0048] Airflow acts on the bottom of the basket 90 through the hollowed-out rotating surface 41a, effectively removing water stains, particulate impurities, etc. after washing. The air knife assembly 43 is fixed to the fixed shaft 11. When the basket 90 passes under the air outlet 431 with the conveyor belt 80, the airflow automatically completes the cleaning, saving mechanical moving parts and reducing energy consumption and failure risk. Designed for the gap between adjacent conveyor belts 80, the basket 90 is suspended in the air (without bottom support) when transitioning between the two conveyor belts 80, achieving unobstructed cleaning and improving the cleaning effect. The air knife assembly 43 is combined with the fixed shaft 11, eliminating the need for additional support structures, saving equipment space, and is suitable for production lines with limited space.

[0049] Specifically, such as Figure 1 and Figure 2 As shown, the air knife assembly 43 includes an air knife housing 432, which is fixed on the fixed shaft 11. The air outlet 431 of the air knife housing 432 extends along the extension direction of the fixed shaft 11. Along the conveying direction of the conveyor belt 80, the air knife housing 432 is located downstream of the nozzle housing 421.

[0050] The nozzle housing 421 first sprays liquid (such as cleaning fluid, alcohol, coating liquid, etc.) onto the basket 90 to complete surface treatment or cleaning. The air knife housing 432 uses high-speed airflow (such as compressed air) to promptly blow away residual liquid and impurities at the bottom of the basket 90, preventing liquid dripping and contamination of the conveyor belt 80 or subsequent processes. Both spraying and blowing are non-contact operations, avoiding mechanical contact that could cause wear or contamination to the basket 90. The air outlet 431 is arranged along the extension direction of the fixed shaft 11, and the length of the air curtain is consistent with the width of the conveyor belt 80, allowing continuous blowing of the entire width area of ​​the bottom of the basket 90 during its movement, avoiding lateral missed areas. The air knife and nozzle share the fixed shaft 11, eliminating the need for an independent support structure, resulting in a small longitudinal space occupation and suitability for compact assembly line designs.

[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, mounting bushings 15 are provided on the first mounting plate 12 and the second mounting plate 13 corresponding to the first winding member 20 and the second winding member 30. The two ends of the first winding member 20 and the two ends of the second winding member 30 are rotatably assembled between the first mounting plate 12 and the second mounting plate 13 through the mounting bushings 15.

[0052] The wound component is rotatably mounted on the mounting sleeve 15. The mounting sleeve 15 can be designed as a sliding bearing with an oil hole or an integrated rolling bearing (such as a deep groove ball bearing). It is lubricated periodically through an oil nozzle. During maintenance, only the sleeve part needs to be maintained, without contact with the wound material. The two ends of the wound component are supported by the mounting plate and the sleeve, forming a symmetrical force-bearing structure, which can effectively resist the axial tension and radial pressure generated during material winding and reduce the bending deformation of the wound component.

[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, the cleaning device at the bottom of the flower basket 90 also includes a sewage tank 70, which is located below the first winding member 20, the second winding member 30 and the rotating member 40.

[0054] Wastewater tank 70 promptly collects wastewater dripping from the bottom of cleaning cloth 50, rotating parts 40, and flower basket 90, preventing particulate impurities and chemicals carried by the wastewater from spreading into the production environment. The wastewater is concentrated within the tank, rather than spreading to the ground or equipment crevices, facilitating regular cleaning (such as emptying or pumping) and reducing manual wiping workload. Centralized wastewater collection allows for unified treatment, complying with environmental regulations and avoiding increased wastewater treatment costs or compliance risks associated with decentralized discharge. Whether the cleaning device uses dry wiping (physical friction from cleaning cloth 50 alone) or wet wiping (in conjunction with liquid spraying), wastewater tank 70 effectively collects generated dust and waste liquid, adapting to different cleaning processes.

[0055] In other embodiments, the wastewater tank 70 may also be connected to a filtration and purification system (such as a filter screen or centrifuge) to recover useful components (such as cleaning agents or alcohol) from the cleaning solution, or to separate solid impurities and reuse the solution, thereby reducing consumable costs.

[0056] In some embodiments, such as Figure 3 As shown, the drive assembly 60 includes a first motor 61 and a second motor 62. The output end of the first motor 61 is connected to the first winding member 20, and the output end of the second motor 62 is connected to the second winding member 30.

[0057] Therefore, the two motors can have their speed, torque, and direction adjusted independently via drivers (such as frequency converters or servo controllers) without interfering with each other. A "single-motor debugging" mode is also supported; for example, the first motor 61 can be started separately to check the smooth unwinding of the cleaning cloth 50, or the second motor 62 can be started separately to test the winding tension. The motors can be coaxially mounted (directly connected) or offset mounted (connected across a transmission component) with the winding, adapting to different equipment space constraints.

[0058] This application also discloses an automated loading and unloading machine, including a basket loading unit, a battery cell transport unit, and a basket unloading unit arranged sequentially. The basket loading unit includes a cleaning device for the bottom of the basket and multiple conveyor belts 80. The cleaning device for the bottom of the basket is disposed in the gap between adjacent conveyor belts 80. The cleaning device for the bottom of the basket in this automated loading and unloading machine is the same as the cleaning device for the bottom of the basket mentioned above. Therefore, the automated loading and unloading machine in this embodiment has roughly the same technical effect as the cleaning device for the bottom of the basket mentioned above.
