Description

Technical Field

[0001] This application relates to the field of battery processing technology, and in particular to a carrier fixture, a conveyor line, and a battery cleaning device. Background Technology

[0002] Cylindrical batteries are another common type of battery product compared to pouch batteries and rectangular batteries. They are composed of a cylindrical steel shell, internal cells, and other accessories. Due to their advantages such as high capacity, good charge and discharge cycle performance, ability to discharge at high current, and stable electrochemical performance, they are widely used in new energy vehicles, power tools, and other products and equipment.

[0003] Traditionally, in the production process of cylindrical batteries, the cylindrical batteries are placed vertically in a tray. When they are transferred to the cleaning section for cleaning, the cylindrical batteries need to be removed from the tray, the tray is removed, and then the cylindrical batteries are laid down. This process involves many steps, poor production continuity, and affects the efficiency of cleaning. Summary of the Invention

[0004] Therefore, it is necessary to provide a carrier fixture, a conveyor line, and a battery cleaning device to address the problems of numerous process steps, poor production continuity, and low cleaning efficiency.

[0005] On the one hand, this application provides a support fixture, which includes:

[0006] Carrier base, the carrier base being used for mounting and mating with a conveyor line; and,

[0007] The carrier mechanism is mounted on the carrier seat. The carrier mechanism includes a carrier base plate, a first carrier component and a second carrier component. The first carrier component and the second carrier component are arranged opposite each other on the carrier base plate at intervals. The first carrier component and the second carrier component are used to load and support the cylindrical battery in a horizontal position.

[0008] The aforementioned carrier fixture is used in the battery cleaning device. Specifically, it is installed on the conveyor line to load and fix cylindrical batteries. Driven by the conveyor line, the carrier fixture can carry the cylindrical batteries and move synchronously, so that the cylindrical batteries pass through the cleaning actuator and receive the cleaning operation of the cleaning actuator. Afterward, the carrier fixture can carry the cylindrical batteries to further flow backward and successively complete the oiling, drying, coding, IR detection, appearance inspection and tray assembly processes, thus completing the cylindrical battery cleaning section processing operation. Specifically, since the carrier mechanism consists of a carrier base plate and a first carrier assembly and a second carrier assembly mounted on the carrier base plate, and the first carrier assembly and the second carrier assembly are arranged at intervals relative to each other, the cylindrical battery can be placed horizontally on the first carrier assembly and the second carrier assembly, thereby exposing the negative terminal surface and circumferential surface of the cylindrical battery. This allows the carrier fixture to always load and support the cylindrical battery throughout the entire processing flow, such as cleaning and oiling, and the cylindrical battery can always move smoothly and synchronously with the carrier fixture. There is no need to separate the cylindrical battery from the carrier fixture, nor is it necessary to perform operations such as laying down the cylindrical battery or removing the carrier fixture, which greatly simplifies the process steps, ensures production continuity, and improves cleaning and processing efficiency.

Detailed Implementation

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0038] This application provides a battery cleaning device, which is part of a battery processing system and configured in a battery cleaning production line. It is mainly used for a series of processes such as cleaning, oiling, and coding of batteries. Optionally, the battery mentioned in this application specifically refers to a cylindrical battery 20.

[0039] For example, the battery cleaning device includes a conveyor line and multiple cleaning actuators 40. The conveyor line includes a conveyor line body and multiple carrier fixtures 10. The conveyor line body can be any of the mature belt conveyor mechanism, sprocket conveyor mechanism, etc., whichever is more readily available in the prior art. It can be flexibly selected according to actual needs and is not particularly limited here.

[0040] In this embodiment, at least a portion of the conveyor line body is arranged in a ring structure. It is easily understood that the entire conveyor line body can be arranged in a ring structure, or the conveyor line body can include a ring segment, an input end (which can be a straight line or other shape), and an output end (which can be a straight line or other shape). The ring segment has a semi-closed ring structure, with one end of the ring segment at the opening connected to one end of the input end, and the other end of the ring segment at the opening connected to the output end, and so on.

[0041] Multiple cleaning actuators 40 are arranged in a ring structure along the extension direction of the main body of the conveyor line. It is easy to understand that the purpose of arranging the main body of the conveyor line in a ring structure is to accommodate more cleaning actuators 40. When the carrier fixture 10 carries the cylindrical battery 20 and moves along the ring conveyor section, it can receive continuous cleaning processing from multiple cleaning actuators 40, thereby greatly improving the cleaning efficiency and cleaning effect.

[0042] It is understandable that multiple cleaning stations are divided along the conveying direction of the main body of the conveyor line, with each cleaning station corresponding to a cleaning actuator 40. Alternatively, two or more cleaning stations may share a single cleaning actuator 40. Preferably, this embodiment uses a scheme where one cleaning station is configured with one cleaning actuator 40. During a cleaning cycle, all cleaning actuators 40 remain in the normally open state. This ensures that when the carrier fixture 10 carrying the cylindrical battery 20 passes through different cleaning stations in sequence, it can receive continuous cleaning processing from different cleaning actuators 40, thus ensuring higher cleaning efficiency.

[0043] Please see Figures 1 to 4 Furthermore, this solution employs multiple carrier fixtures 10 sequentially mounted on the main body of the conveyor line along its conveying direction. Each carrier fixture 10 carries at least one horizontally positioned cylindrical battery 20, and the cleaning actuator 40 cleans the cylindrical batteries 20 on the corresponding carrier fixture 10. Therefore, within a single cleaning cycle, multiple cylindrical batteries 20 can be cleaned simultaneously, significantly improving the cleaning efficiency of the battery cleaning device and thus increasing the production efficiency of the cylindrical batteries 20.

[0044] It should be noted that the cylindrical battery 20 is laid horizontally, which means that the central axis of the cylindrical battery 20 is on a horizontal plane.

[0045] Based on the above embodiments, the cleaning actuator 40 includes a power source, a cleaning component, and a cleaning brush 44. Both the cleaning component and the cleaning brush 44 are connected to the power source. The cleaning component is disposed above the support fixture 10 and is used to clean the circumferential surface of the cylindrical battery 20. The cleaning brush 44 is disposed on the side of the support fixture 10 and is used to clean the end face of the cylindrical battery 20.

[0046] It should be noted that the cleaning of the end face of the cylindrical battery 20 mentioned above specifically refers to the negative end face of the cylindrical battery 20 that is away from the positive terminal.

[0047] During operation, the power source synchronously outputs driving force to the cleaning assembly and cleaning brush 44, enabling them to simultaneously clean the circumferential and end faces of the cylindrical battery 20. This increases the cleaning area of ​​the cylindrical battery 20 per unit time, thereby improving cleaning efficiency. Furthermore, by sharing a single power source with the cleaning assembly and cleaning brush 44, the number of power sources required is reduced, thus lowering costs and simplifying the structure of the battery cleaning device.

[0048] Optionally, the power source can be a combination of power sources such as a motor and synchronous transmission chain, or a motor and synchronous transmission belt.

[0049] Please continue reading. Figure 3 and Figure 4In some embodiments, the cleaning assembly includes a bracket 41, a first roller brush 42, and a second roller brush 43, which are rotatably arranged side-by-side on the bracket 41; wherein the rotational torque of the first roller brush 42 is greater than that of the second roller brush 43. For example, the bracket 41 is fixedly mounted on a peripheral component (such as a housing or frame), thereby suspending the entire cleaning assembly above the movement path of the carrier fixture 10. When the cylindrical battery 20 moves into the cleaning station along with the carrier fixture 10, the upward-facing circumferential surface of the cylindrical battery 20 automatically contacts the first roller brush 42 and the second roller brush 43, driving the first roller brush 42 and the second roller brush 43 to rotate, thereby achieving a cleaning process on the circumferential surface of the cylindrical battery 20.

[0050] Furthermore, because the rotational torques of the first roller brush 42 and the second roller brush 43 are unequal, the cylindrical battery 20 is driven to rotate around its own axis under the action of the torque difference. In this way, the first roller brush 42 and the second roller brush 43 can achieve continuous rotational contact with the entire circumference of the cylindrical battery 20 from a fixed position, thus completing continuous cleaning of the entire circumference of the cylindrical battery 20, achieving better cleaning results and improving cleaning efficiency. The above structural design allows for the rotation of the original battery 20 without the need for a specially designed and installed drive device, saving on drive equipment costs, reducing space occupation, simplifying the structure of the cleaning components, and improving operational reliability.

[0051] It is worth noting that the battery cleaning device also includes a water spraying mechanism, which is installed on one side or above the conveyor line. The water spraying mechanism sprays water onto the cylindrical battery 20 after the carrier jig 10 carries the cylindrical battery 20 into the cleaning station, so that the water can carry away the dirt and impurities washed off by the cleaning brush 44, the first roller brush 42 and the second roller brush 43 from the surface of the cylindrical battery 20, so as to obtain a better cleaning effect.

[0052] like Figure 1 and Figure 2 As shown, a carrier fixture 10 is presented in an embodiment of this application, including a carrier base 11, a carrier mechanism 12, and an electronic information tag 30.

[0053] The carrier base 11 is used to mate with the conveyor line. This allows the carrier base 11 to transmit the power of the conveyor line to the carrier fixture 10, so that the carrier fixture 10 can move along with the conveyor line.

[0054] The support mechanism 12 is mounted on the carrier base 11 and is used to load and support the cylindrical battery 20. Optionally, the support mechanism 12 can be integrally formed with the carrier base 11 or it can be detachably connected, depending on the actual needs. For example, in this embodiment, the support mechanism 12 and the carrier base 11 preferably adopt an integral structure to ensure higher connection strength and improve the overall structural performance of the support fixture 10.

[0055] The support mechanism 12 includes a support base plate 121, a first support assembly and a second support assembly. The first support assembly and the second support assembly are disposed on the support base plate 121 at intervals and opposite to each other. The first support assembly and the second support assembly are used to load and support the cylindrical battery 20 in a horizontal position.

[0056] In summary, implementing the technical solution of this embodiment will have the following beneficial effects: The carrier fixture 10 of the above solution is applied in the battery cleaning device, specifically installed on the conveyor line and used to load and fix the cylindrical battery 20. Under the drive of the conveyor line, the carrier fixture 10 can carry the cylindrical battery 20 to move synchronously, so that the cylindrical battery 20 passes through the cleaning execution mechanism 40 and receives the cleaning operation of the cleaning execution mechanism 40. After that, the carrier fixture 10 can also carry the cylindrical battery 20 to further flow backward and successively complete the oiling, drying, coding, IR detection, appearance inspection and tray assembly processing steps, thus completing the cylindrical battery 20 cleaning section processing operation.

[0057] Specifically, since the support mechanism 12 consists of a support base plate 121 and a first support assembly and a second support assembly mounted on the support base plate 121, and the first support assembly and the second support assembly are arranged at intervals relative to each other, the cylindrical battery 20 can be placed on the first support assembly and the second support assembly in a horizontal position, thereby exposing the negative terminal surface and circumferential surface of the cylindrical battery 20. This allows the support fixture 10 to always load and support the cylindrical battery 20 during the entire processing flow, such as cleaning and oiling. The cylindrical battery 20 can always move smoothly and synchronously with the support fixture 10. It is not necessary to separate the cylindrical battery 20 from the support fixture 10, nor is it necessary to perform operations such as laying down the cylindrical battery 20 or removing the support fixture 10. This greatly simplifies the process steps, ensures production continuity, and improves cleaning and processing efficiency.

[0058] The carrier fixture 10 in this solution has the ability to support and lift the cylindrical battery 20 throughout the entire process of each step of processing. Unlike existing technologies, it does not require changing or removing the tray. In other words, by using the carrier fixture 10 as a carrier for the cylindrical battery 20, a one-stop high-speed production solution for carrier cleaning is realized. It can complete cleaning, oiling, drying, coding, IR detection, appearance inspection, and tray assembly processes. The equipment layout is compact, and the turntable station can be flexibly configured. In addition, it can also complete the high-speed production of cylindrical batteries 20 and the discharge of NG (non-compliant) batteries.

[0059] Please continue reading. Figure 2 and Figure 3 Furthermore, based on any of the above embodiments, the electronic information tag 30 is installed on the carrier seat 11, and the electronic information tag 30 is used to communicate and cooperate with the information reader installed on the conveyor line.

[0060] Specifically, the carrier base 11 has a cylindrical shape, and therefore has a top surface 111 and a bottom surface 112 that are arranged opposite to each other. The top surface 111 and the bottom surface 112 are two opposite sides in the height direction of the carrier base 11. The support mechanism 12 is installed on the top surface 111, and the bottom surface 112 is recessed to form a mounting hole 112a, in which the electronic information tag 30 is installed.

[0061] For example, the electronic information tag 30 and the information reader use RFID (Radio Frequency Identification) technology. Its working principle is that the information reader and the electronic information tag 30 conduct non-contact data communication to achieve the purpose of identifying the target.

[0062] In other words, each cylindrical battery 20 on the carrier fixture 10 has its own basic battery information, which may include, but is not limited to, manufacturing time, batch number, and power capacity. This basic battery information is stored in its own electronic information tag 30. Furthermore, as the carrier fixture 10 follows the conveyor line through different workstations such as cleaning, oiling, and coding, the corresponding processing completion information is also stored in the electronic information tag 30. Based on this, information readers installed on the conveyor line can monitor and trace the various information of each cylindrical battery 20.

[0063] Specifically, the carrier mechanism 12 installed on the carrier 11 can load and support the cylindrical battery 20 to ensure that the cylindrical battery 20 can move smoothly and synchronously with the carrier fixture 10. In addition, since the carrier 11 is also equipped with an electronic information tag 30, when the cylindrical battery 20 flows with the carrier fixture 10, it can cooperate with the information reader installed on the conveyor line. The information reader can continuously read and record the relevant information of the cylindrical battery 20 in real time, thereby realizing the information traceability of the cylindrical battery 20, binding and monitoring the process information, and ensuring that the production and processing of the cylindrical battery 20 is controllable and safe.

[0064] In the installed and used state, because the carrier mechanism 12 is installed on the top surface 111 of the carrier base 11, the cylindrical battery 20 placed on the carrier mechanism 12 can be completely exposed below the water spraying mechanism, which facilitates the water spraying mechanism to directly spray water onto the cylindrical battery 20 to ensure the cleaning effect. At this time, the electronic information tag 30 is hidden in the mounting hole 112a on the bottom surface 112, so the water spraying is not likely to directly contact the electronic information tag 30, and the cleaning water flowing down the outer wall of the carrier base 11 is also unlikely to come into contact with the electronic information tag 30, thus ensuring the safe and reliable operation of the electronic information tag 30. In addition, the hidden installation method of the electronic information tag 30 also enables it to be used in the entire process of cleaning and oiling, without the need for disassembly, and it is not easy to be lost, ensuring the safe and reliable recording and traceability of the process information of the cylindrical battery 20.

[0065] Please continue reading. Figure 1 and Figure 1 Furthermore, based on the above embodiments, the carrier base 11 is also provided with a positioning groove 113, which extends along the direction from the top surface 111 to the bottom surface 112. The positioning groove 113 is used to engage with a positioning body on the conveyor line, thereby realizing the installation and positioning of the carrier fixture 10 on the conveyor line.

[0066] Furthermore, the carrier seat 11 is also provided with a foolproof part 114, which is located on the side of the groove opening of the positioning groove 113. The foolproof part 114 facilitates visual inspection by processing personnel or automatic detection by visual inspection equipment, preventing the carrier fixture 10 from being installed on the conveyor line in the wrong direction, which could cause damage to the cylindrical battery 20 during subsequent cleaning.

[0067] Furthermore, the carrier seat 11 is also provided with multiple guide grooves 115, which are located on different sides of the carrier seat 11. Since the carrier fixture 10 needs to move along the circular path of the conveyor line, the guide grooves 115 can slide and engage with the guide protrusions on one side of the conveyor line when making turns, thereby guiding the movement of the carrier fixture 10, ensuring the stability of the carrier fixture 10, and ensuring that the carrier fixture 10 will not fall off the conveyor line even when it is driven by the conveyor line to move at high speed in a circular direction.

[0068] Please continue reading. Figure 3In some embodiments, the first support assembly includes a first support roller 123 and two first support columns 122, and the second support assembly includes a second support roller 125 and two second support columns 124. The support base plate 121 is mounted on the top surface 111 of the carrier seat 11. The two first support columns 122 are arranged on one side of the support base plate 121 in the width direction and are spaced apart along the length direction of the support base plate 121. The two ends of the first support roller 123 are respectively connected to the corresponding first support column 122. The two second support columns 124 are arranged on the other side of the support base plate 121 in the width direction and are spaced apart along the length direction of the support base plate 121. The two ends of the second support roller 125 are respectively connected to the corresponding second support column 124. The first support roller 123 and the second support roller 125 are arranged side by side and spaced apart for loading and supporting the cylindrical battery 20.

[0069] The support base plate 121 is assembled and connected to the carrier seat 11 to achieve the assembly and fixation of the support mechanism 12 and the carrier seat 11. The two first pillars 122 and the two second pillars 124 respectively support the corresponding first support rollers 123 and second support rollers 125 to a certain height position, so as to avoid the support base plate 121 from contacting and interfering with the circumferential surface of the cylindrical battery 20 after the cylindrical battery 20 is placed on the first support rollers 123 and second support rollers 125, which would prevent the cylindrical battery 20 from being effectively supported by the first support rollers 123 and second support rollers 125 and affect the installation stability of the cylindrical battery 20. Furthermore, the first and second support rollers 123 and 125, which are arranged side by side at intervals, can simultaneously form line contact with different parts of the circumference of the cylindrical battery 20, providing excellent support stability. Under the weight of the cylindrical battery 20, the first and second support rollers 123 and 125 can simultaneously form a certain clamping and limiting effect on the cylindrical battery 20, preventing the cylindrical battery 20 from flying out when moving in the circumferential direction at excessive speed.

[0070] In this embodiment, the cylindrical battery 20 lies horizontally on the first carrier roller 123 and the second carrier roller 125. During cleaning, the cylindrical battery 20 can be rotated, thereby achieving all-round cleaning of the cylindrical battery 20.

[0071] As described above, in order to reduce the contact area between the first and second support rollers 123 and 125 and the circumferential and end faces of the cylindrical battery 20, thereby reducing the frictional resistance generated by relative rotation and making it easier for the cylindrical battery 20 to rotate smoothly and effectively under the drive of the first roller brush 42 and the second roller brush 43 that form a torque difference, in some embodiments, a first clearance groove 126 is recessed in the middle of both the first and second support rollers 123 and 125; and / or a second clearance groove 127 is recessed at both ends of both the first and second support rollers 123 and 125. Preferably, in this embodiment, the first clearance groove 126 and the second clearance groove 127 coexist.

[0072] Furthermore, the upper surface of the support plate 121 facing away from the carrier seat 11 is provided with at least one drainage ramp 128. The drainage ramp 128 makes it easier for water poured onto the support plate 121 to flow down and drain away, preventing it from accumulating on the support plate 121. Preferably, in this embodiment, the support plate 121 is rectangular, and a drainage ramp 128 is provided at each of its two ends near its length direction, which helps to enhance drainage capacity.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
