Description

Technical Field

[0001] This invention relates to the field of battery technology, and in particular to a battery rejection device, rejection method, and battery production line. Background Technology

[0002] Among related technologies, cam-splitting turret equipment has high production efficiency and small space occupation, so it is widely used in battery production lines, such as for battery filling lines, cleaning lines before filling hole sealing, and filling hole sealing lines.

[0003] However, during the processing of cam-splitting turret equipment, defective batteries need to be removed by a battery rejection device. However, the linear speed of the batteries rotating inside the turret is relatively fast, making it difficult to accurately remove defective batteries. Furthermore, the battery rejection process may cause the batteries to tip over, which poses a certain safety hazard for some battery-powered production lines. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a battery rejection device with higher rejection reliability and stability.

[0005] This application also proposes a method for rejecting battery rejecting devices.

[0006] This application further proposes a battery production line employing the aforementioned battery rejection device.

[0007] In a first aspect, this application proposes a battery rejection device, comprising: a transition disk, a rejection channel, and a rejection component. The edge of the transition disk has a plurality of receiving portions spaced apart along a first direction, each receiving portion being used to receive a positioning member, in which a battery is placed. The running trajectory of the transition disk is in the first direction. The rejection channel is opposite to the transition disk and located radially outside the receiving portion. The rejection component is located on the side of the receiving portion away from the rejection channel and is used to reject defective batteries. The transition disk is configured to run for a first predetermined time to receive processed batteries and / or defective batteries to the receiving portion, and to pause for a second predetermined time so that the rejection component separates the defective battery and the positioning member from the receiving portion within the second predetermined time.

[0008] According to the battery rejection device of this application embodiment, by moving and stopping the transition plate and cooperating with the rejection component within a second set time, defective batteries located between the rejection component and the rejection channel are rejected. This can reduce the matching accuracy requirement of the rejection component, and can more accurately reject defective batteries, reducing the probability of false rejection due to mismatch in rejection timing.

[0009] According to some embodiments of this application, the rejection channel has at least two battery channels corresponding to the receiving portion. The rejection component includes: a plurality of toggle plates and at least two drive members. The toggle plates are rotatably disposed on the transition plate in a one-to-one correspondence with the receiving portion. The drive members are used to toggle the toggle plates corresponding to the receiving portion opposite to the battery channel to reject defective batteries.

[0010] In the above technical solution, multiple batteries can be moved out in groups to be opposite to multiple battery channels. Even if multiple defective batteries occur in succession, defective batteries can be stably removed, which can reduce the probability of false removal and failure to remove.

[0011] According to some embodiments of this application, the included angle between adjacent driving members is consistent with the included angle between two adjacent receiving parts.

[0012] In the above technical solution, on the one hand, it can realize the independent rejection of defective batteries through multiple channels, which can improve the rejection accuracy and reliability, reduce the probability of batteries tipping over, and thus improve safety. On the other hand, it can simultaneously reject multiple defective batteries, so that when multiple consecutive defective batteries appear on the transition plate, they can also be accurately rejected, reducing the probability of failure to reject them.

[0013] According to some embodiments of this application, the actuating plate includes a first actuating plate and a second actuating plate. The first actuating plate and the second actuating plate are disposed on two opposite surfaces of the transition plate along its own axial direction, and are rotatably disposed on the radial inner side of the receiving part by a rotating shaft, so as to actuate the positioning member radially outward.

[0014] In the above technical solution, the first actuating plate and the second actuating plate are arranged opposite each other in the axial direction of the transition plate, and the first actuating plate and the second actuating plate are pivotally connected to the transition plate through the same rotating shaft, so that the first actuating plate and the second actuating plate can synchronously push the battery to move radially out of the receiving part, so that the force distribution when the battery is rejected is more uniform, reducing the probability of the battery tipping over, thereby improving the safety and reliability of the battery rejection device.

[0015] According to some embodiments of this application, the rejection component further includes a reset member disposed on the rotating shaft and used to drive the toggle plate to reset.

[0016] In the above technical solution, the reset structure of the first and second actuating plates is simpler, which can simplify the structure of the rejection section and reduce the cost of the battery rejection device.

[0017] According to some embodiments of this application, the battery rejection device further includes: a cam divider connected to a transition disk, the cam divider being used to drive the transition disk to rotate according to the interval angle between at least two adjacent receiving parts.

[0018] In the above technical solution, the transition plate is stopped and started by setting a cam divider, and at least two batteries on the transition plate are selectively rejected by the rejection component. On the one hand, the matching accuracy requirement of the rejection component can be reduced, and defective batteries can be rejected more accurately, reducing the probability of false rejection due to mismatch of rejection timing. On the other hand, batteries can be selectively rejected in groups, and even if multiple defective batteries appear in succession upstream, they can be accurately rejected, reducing the probability of failure to reject them, thereby improving the reliability and stability of the battery rejection device.

[0019] According to some embodiments of this application, the cam divider is used to drive the transition disk to rotate according to the interval angle between adjacent multiple receiving parts, and the number of adjacent multiple receiving parts is the number of driving members.

[0020] According to some embodiments of this application, the rejection channel has multiple guide bars, and adjacent guide bars define battery channels, each battery channel being used for the flow of defective batteries and positioning elements.

[0021] According to some embodiments of this application, the number of battery channels is the same as the number of driving components.

[0022] In the above technical solution, by setting up multiple battery channels, and the number of battery channels being consistent with the number of receiving parts that can simultaneously reject defective batteries, defective batteries rejected by different receiving parts can enter different battery channels. Guide bars are used to guide and limit the movement of the batteries, which can reduce the probability of collisions between multiple batteries when there are multiple batteries on the rejection channel, and can also reduce the probability of batteries tipping over, thereby further improving rejection stability and safety.

[0023] According to some embodiments of this application, the cross-sectional area of ​​the guide bar near one end of the transition disk gradually decreases in the direction toward the transition disk.

[0024] In the above technical solution, a guide portion can be provided at one end of the guide bar adjacent to the transition disk. The guide portion of the guide bar is constructed such that the cross-sectional area gradually decreases in the direction adjacent to the transition disk, so that the ends of two adjacent guide bars adjacent to the transition disk can form a flared structure, so as to guide the battery into the battery channel, reduce the difficulty of the battery entering the battery channel, and effectively guide the battery to reduce the probability of the battery tipping over.

[0025] Secondly, this application proposes a method for rejecting batteries using a battery rejection device, comprising:

[0026] This process takes over from the previous step and completes the processing of batteries and defective batteries.

[0027] Remove defective batteries; wherein, within a first set time period, processed batteries and defective batteries are accepted, and within a second set time period, defective batteries are removed.

[0028] According to the battery rejection method of the embodiment of this application, the rejection of defective batteries can be decoupled from the acceptance and transfer of batteries by the transition plate. The acceptance of batteries is carried out within a first set time, and the rejection of defective batteries is carried out within a second set time. During the second set time, the transition plate stops rotating, which can improve the rejection accuracy and rejection quality, and can realize the simultaneous rejection of multiple defective batteries in multiple channels, so as to solve the technical problem that existing rejection devices are difficult to reject multiple defective batteries at the same time.

[0029] Thirdly, this application proposes a battery production line, including: a battery processing device, a feeding turntable, and a battery rejection device. The battery processing device has a conveying device and is used to process batteries. The feeding turntable is connected to the conveying device and is located downstream of the battery processing device, and is used to receive processed batteries and defective batteries. The transition plate is connected to the conveying device and is located downstream of the feeding turntable, and is used to reject defective batteries or transfer processed batteries.

[0030] According to the battery production line of this application embodiment, the unloading turntable is used to unload the processed batteries on the battery processing device. After unloading, the batteries can flow through the battery rejection device and reject defective batteries. This can realize automated rejection and reduce the probability of incorrect rejection and failure to reject, thereby improving the reliability and safety of the battery production line.

[0031] According to some embodiments of this application, the battery production line further includes a loading line and a unloading line. The loading line is located upstream of the battery processing device and is used to supply the batteries to be processed and the positioning components to the battery processing device. The unloading line is located downstream of the transition plate and is used to receive the processed batteries and the positioning components.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0061] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0062] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0063] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0067] In this application, "multiple" means two or more (including two).

[0068] A single battery cell can be a rechargeable battery. A rechargeable battery is a battery cell that can be recharged after it has been discharged, allowing the active materials to be activated and the cell to continue to be used.

[0069] The battery processed in this embodiment is a cylindrical battery. The cylindrical battery includes a cylindrical housing, an end cap, and an electrode assembly. The housing defines an accommodating space with an installation opening. The electrode assembly and an insulating cover are disposed inside the housing, and the installation opening is sealed by the end cap.

[0070] For example, the housing is generally cylindrical and open at one axial end to form a receiving space with an installation port. Electrode components and other functional components such as insulating covers can be installed in the receiving space. The end cap is closed on the installation port of the housing to isolate the internal environment of the battery cell from the external environment. The shape of the end cap is adapted to the shape of the housing. The end cap can be supported by a material with a certain hardness and strength (such as aluminum alloy or carbon fiber plate). The end cap can effectively protect the safety and reliability of the internal components of the housing when squeezed or impacted.

[0071] In some embodiments, the end cap may also be provided with a pressure relief mechanism for releasing internal pressure when the internal pressure or temperature of the battery cell reaches a threshold. The end cap can also be made of various materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and this application embodiment does not impose any special limitations on this.

[0072] In some embodiments, an insulating cover may be provided inside the end cap. The insulating cover can be used to isolate the electrical connection components inside the housing from the end cap to reduce the risk of short circuits. For example, the insulating cover may be made of plastic, rubber, etc., to achieve insulation protection.

[0073] The housing is a component used to fit with the end cap to form the internal environment of a battery cell, wherein the formed internal environment can accommodate electrode components, electrolyte, and other parts. The housing and end cap can be separate components, and a mounting port can be provided on the housing. The end cap closes the opening at the mounting port to form the internal environment of the battery cell. The housing can be cylindrical.

[0074] Electrode assemblies are the components within a single battery cell where electrochemical reactions occur. A casing may contain one or more electrode assemblies. Electrode assemblies are primarily formed by winding or stacking positive and negative electrode sheets, typically with a separator between them. The portions of the positive and negative electrode sheets containing active material constitute the main body of the electrode assembly, while the portions without active material each form a tab. The positive and negative tabs can be located together at one end of the main body or separately at both ends. During the charging and discharging process of the battery, the positive and negative active materials react with the electrolyte, and the tabs connect to the electrode terminals to form a current loop.

[0075] It should be noted that the manufacturing process of a cylindrical battery includes at least the following: preparation of electrode components, battery packaging, and battery testing. Battery packaging includes multiple steps such as inserting electrode components into the casing, welding the tabs to the output terminals after inserting the casing, battery electrolyte injection, formation after electrolyte injection, and sealing of the electrolyte injection hole.

[0076] In the existing technology, during the battery processing, it is necessary to remove defective batteries (such as defective batteries in the packaging process, defective batteries that do not meet the requirements in the battery testing process, and batteries that do not meet the requirements in the cleaning of the electrolyte filling hole). However, the accuracy of removing defective batteries is difficult to guarantee, and batteries may be knocked over or removed by mistake. In the case of battery processing after electrolyte filling, knocking over the battery also poses a safety hazard.

[0077] In other words, during battery processing, the battery transfer speed is relatively high. However, if the battery rejection device directly rejects the batteries during the transfer process, the rejection accuracy will be low, and the probability of knocking over batteries during rejection will be high, resulting in lower safety. For example, when using a cam-type turret equipment for battery processing, the battery transfer linear speed is high, requiring precise control of the rejection timing of the battery rejection device. The battery rejection device needs to be triggered with a delay during the rotation of the transition plate. When the defective battery moves to the predetermined position, it should be rejected. The rotation of the transition plate, the arrival of the defective battery, and the triggering of the battery rejection device need to be precisely synchronized. However, the high battery transfer speed is necessary to meet processing efficiency requirements, which will also increase the probability of batteries being knocked over or kicked incorrectly. Furthermore, when there are many defective batteries, rejection failures are more likely to occur.

[0078] Based on this, this application proposes a battery rejection device in which the transition disk moves and stops at a certain time ratio, and the rejection component can reject the battery during the time the transition disk stops. This reduces the synchronization requirements of the rotation of the transition disk, the arrival of defective batteries, and the triggering of the rejection component, thereby reducing the probability of kicking the wrong battery or knocking it over. This improves the rejection accuracy and also reduces safety hazards.

[0079] It is understandable that after the electrolyte is injected, the battery is charged. When the battery rejection device is used on the battery production line after the electrolyte is injected, such as in the cleaning equipment for the electrolyte injection holes (equipment that cleans the area of ​​the electrolyte injection holes of the batteries that have been injected), the probability of the charged battery being kicked over is lower, and the safety is higher.

[0080] It should be noted that the battery production line in this application embodiment can be any battery processing production line such as a battery liquid filling line, a cleaning equipment, or an electrode assembly casing line.

[0081] For example, an embodiment of the present application uses a battery production line as a battery cleaning production line, and describes an embodiment in which a battery rejection device is used to clean the battery filling hole and reject defective batteries.

[0082] First, based on Figure 1 , Figure 2 as well as Figure 7 The overall cleaning process of the battery filling hole cleaning device 100 according to an embodiment of this application will be specifically described.

[0083] The cleaning equipment 100 includes, from upstream to downstream, the following components arranged sequentially along the battery flow path: a feeding line 400, a feeding turntable 200 (with a conveying device 110 and a clamp assembly 120 at the same station), a discharging turntable 300, a battery rejection device 600, and a discharging line 500.

[0084] The feeding line 400 includes a feeding channel, a first drive module, and a transition ratchet 410. Batteries to be cleaned flow in the feeding channel, and the transition ratchet 410 can block and guide the movement of the batteries to the feeding turntable 200.

[0085] The feeding turntable 200 is equipped with a first camera module 420 and a barcode scanning module. After the battery enters the feeding turntable 200, the barcode scanning module can sense the electronic tag on the positioning component 800 (such as a cup) and read the battery information. The first camera module 420 above the feeding turntable 200 can determine whether there are glue nails on the battery entering the feeding turntable 200.

[0086] The cam divider 700 drives the first turntable 111 to rotate. The cam divider 700 can rationally allocate the travel and stop ratio of the first turntable 111 according to a specific drive angle (such as the angular interval between adjacent tooling groups). That is, after rotating by a certain angle according to the drive angle, it stops for a period of time. During rotation, batteries can be loaded and unloaded, and the lifting and clamping of the batteries to be cleaned can be completed simultaneously. Battery cleaning can be performed during the stop period. The clamping assembly 120 is set on the first turntable 111, and multiple clamping assemblies 120 can be used to assemble batteries and position them. The turret 112 is fixed. When the first turntable 111 rotates, the first cam groove 1121 and the second cam groove 1122 on the turret 112 can drive the release member 123 and the clamp 124 respectively, so that the battery can be pushed against the positioning cover plate 125, which facilitates the cleaning component 130 to position the battery. The clamp 124 can clamp the battery to reduce the probability of movement during the battery cleaning process and improve the positioning accuracy and cleaning accuracy. The cleaning component 130 can be arranged at a reasonable position around the first turntable 111 to control the cleaning of the battery with glue nails based on the detection information transmitted by the first camera module 420.

[0087] The feeding turntable 300 is also equipped with a second camera module 510. The feeding turntable 300 is located downstream of the cleaning equipment 100 and can receive the batteries fed by the cleaning equipment 100. The second camera module 510 can perform visual inspection on the fed batteries to detect whether the batteries have been cleaned and the amount of offset after cleaning.

[0088] The battery rejection device 600 is located downstream of the unloading turntable 300. The battery rejection device 600 can reject defective batteries from the unloading batteries based on the detection information of the first camera module 420 and the second camera module 510. Defective batteries include: batteries without glue pins identified by the first camera module 420, and batteries whose offset exceeds the threshold after cleaning identified by the second camera module 510.

[0089] A discharge line 500 is provided downstream of the battery rejection device 600, which is suitable for removing the cleaned batteries.

[0090] For example, such as Figure 2 As shown, the cam divider 700 has an output gear 710, which can be constructed as an incomplete gear. The first turntable 111 is connected to the first meshing tooth 113, the feeding turntable 200 is connected to the second meshing tooth 210, the unloading turntable 300 is connected to the third meshing tooth 310, and the transition plate 610 is connected to the fourth meshing tooth 612. The output gear 710 meshes with the first meshing tooth 113 for transmission. The first meshing tooth 113 also directly or indirectly meshes with the second meshing tooth 210, the third meshing tooth 310, and the fourth meshing tooth 621, so that the feeding turntable 200, the first turntable 111, the unloading turntable 200, and the transition plate 610 rotate synchronously according to a first set time and stop for a second set time.

[0091] Of course, such as Figure 8 As shown, weight reduction holes 103 can be provided on the bodies of the feeding turntable 200, the first turntable 111, the unloading turntable 200, and the transition plate 610. Limiting rods 102 can be provided on the battery transfer areas between the feeding turntable 200 and the first turntable 111, the battery transfer areas between the first turntable 111 and the unloading turntable 200, and the battery transfer areas between the unloading turntable 200 and the transition plate 610. The limiting rods 102 are used to limit the battery during the transfer process to prevent jamming or detachment of the battery.

[0092] It should be noted that the battery filling hole cleaning device 100 in this application embodiment is used to clean the battery after filling and the filling hole is sealed with a rubber nail. After cleaning, the battery needs to be transferred to the next process for welding the sealing cap of the filling hole area.

[0093] The following is for reference. Figures 1-12A battery rejection device 600, a rejection method, and a battery production line according to embodiments of the present invention are described.

[0094] like Figure 7 and Figure 8 As shown, this application proposes a battery rejection device 600, which is used to reject defective batteries. The battery rejection device 600 includes: a transition plate 610, a rejection channel 630, and a rejection component 620.

[0095] The edge of the transition disk 610 has a plurality of receiving portions 611 spaced apart along a first direction. Each receiving portion 611 is used to receive a positioning member 800, in which a battery is placed. The running trajectory of the transition disk 610 is in the first direction. The rejection channel 630 is opposite to the transition disk 610 and is located radially outside the receiving portion 611. The rejection assembly 620 is located on the side of the receiving portion 611 away from the rejection channel 630 and is used to reject defective batteries.

[0096] The transition plate 610 is configured to run for a first set time to receive the processed battery and / or defective battery to the receiving part 611, and pause for a second set time so that the rejection component 620 separates the defective battery and the positioning member 800 from the receiving part 611 within the second set time.

[0097] Specifically, the first direction is the rotation direction, which can be counterclockwise or clockwise. The transition disk 610 can rotate along the first direction, and during the rotation, it can rotate for a first set time and stop rotating for a second set time. During the rotation for the first set time, at least one of the multiple receiving parts 611 provided on the transition disk 610 along the first direction can receive the processed battery or the defective battery, or multiple of the multiple receiving parts 611 can respectively receive the processed battery and the defective battery. Then, the defective battery received by the transition disk 610 can be removed into the rejection channel 630 located on the radial outer side of the transition disk 610 by the rejection component 620.

[0098] In other words, the transition plate 610 has a plurality of receiving portions 611 distributed along the circumferential direction (i.e., the first direction). The receiving portions 611 can be constructed as an arc-shaped open structure. When the transition plate 610 moves to be tangent to the first turntable 111 of the conveying device 110 at the upstream station, the receiving portion 611 can receive the battery from the first turntable 111. Among the batteries received by the receiving portion 611, there may be defective batteries (such as: batteries that have not been cleaned, or batteries that do not meet the requirements after cleaning). When the transition plate 610 rotates and moves the received battery between the rejection component 620 and the rejection channel 630, the rejection component 620 can reject the defective battery that needs to be rejected.

[0099] In this way, defective batteries can be rejected within the stop time (second set time). The coupling accuracy requirements of the transition plate 610, the relative position of the defective battery, and the triggering delay of the rejection component 620 are lower. There is no need to match the rejection timing. It is no longer affected by the equipment communication time and the reaction time of the rejection component 620. Defective batteries can be rejected more accurately and reliably.

[0100] It should be pointed out that, in combination Figure 8 and Figure 10 As shown, the rejection channel 630 is opposite to the transition plate 610 and is located radially outside the receiving part 611 to receive the batteries rejected by the rejection assembly 620.

[0101] Specifically, the rejection channel 630 is used to receive batteries rejected by the receiving part 611. The side of the receiving part 611 that is radially adjacent to the axis of the transition disk 610 is defined as the radial inner side, and the side of the receiving part 611 that is radially away from the axis of the transition disk 610 is defined as the radial outer side. The actuating plate 621 located on the radial inner side of the receiving part 611 can be used to reject batteries in the receiving part 611. The rejection channel 630 located on the radial outer side of the receiving part 611 is used to receive the rejected batteries, so that the rejected batteries can directly enter the rejection channel 630, improving the reliability of the transfer of defective batteries, further reducing the probability of them tipping over, and improving safety.

[0102] According to the battery rejection device 600 of this application embodiment, by moving and stopping the transition disk 610 and cooperating with the rejection component 620 within a second set time, defective batteries located between the rejection component 620 and the rejection channel 630 are rejected. This can reduce the matching accuracy requirement of the rejection component 620, and can reject defective batteries more accurately, reducing the probability of false rejection caused by mismatch in rejection timing.

[0103] It should be noted that when the battery rejection device 600 of this application embodiment is used for rejecting charged batteries, the probability of accidental rejection and failure to reject is lower, which can also improve the safety of the battery production line.

[0104] like Figure 7 and Figure 8 As shown, the rejection channel 630 has at least one battery channel 632 corresponding to the receiving part 611. The rejection assembly 620 includes: a plurality of toggle plates 621 and at least one drive member 622. The toggle plates 621 are rotatably disposed on the transition disk 610 in a one-to-one correspondence with the receiving parts 611. The drive member 622 is used to toggle the toggle plate 621 corresponding to the receiving part 611 opposite to the battery channel 632 to reject defective batteries.

[0105] In other words, the rejection channel 630 includes multiple battery channels 632 corresponding to the receiving section 611, and the rejection assembly 620 includes multiple toggle plates 621 and multiple drive members 622. The drive members 622 are used to toggle the toggle plates 621 corresponding to the receiving section 611 opposite to the battery channel 632, thereby rejecting the defective batteries in the corresponding receiving section 611. That is, the multiple receiving sections 611 can receive batteries in groups, receiving two or more batteries at a time until they are opposite to the battery channel 632. Any one or more defective batteries in the multiple receiving sections 611 that need to be rejected can be rejected by the corresponding drive members 622 in conjunction with the toggle plates 621.

[0106] In this way, multiple batteries can be moved out in groups to be opposite to multiple battery channels 632. Even if multiple defective batteries occur in succession, defective batteries can be stably removed, which can reduce the probability of false removal and failure to remove.

[0107] It is understandable that the number of driving components 622 is the same as the number of battery channels 632, and the included angle between adjacent driving components 622 is the same as the included angle between two adjacent receiving parts 611.

[0108] like Figure 8 As shown, according to some embodiments of this application, there are multiple toggle back plates, and each receiving part 611 is provided with a corresponding toggle plate 621.

[0109] Specifically, there are multiple actuating plates 621, and each actuating plate 621 is arranged in a one-to-one correspondence with the receiving part 611. The receiving part 611 located between the rejection channel 630 and the driving member 622 can reject defective batteries through the corresponding actuating plate 621. Each battery can be independently rejected by the actuating plate 621 that is arranged in a one-to-one correspondence with the receiving part 611, which can further improve the rejection accuracy and further reduce the probability of the battery tipping over during the rejection process, thereby improving safety.

[0110] like Figure 8 As shown, there are at least two drive cylinders, and the drive member 622 is located radially inside the receiving part 611 and is adapted to drive the removal part to move.

[0111] Specifically, the number of drive components 622 should be consistent with the number of batteries received by the transition plate 610 within the first set time period. Correspondingly, within each second set time period, the number of receiving parts 611 located between the battery channel 632 and the drive components 622 should be consistent with the number of batteries received by the transition plate 610 within the first set time period. This allows multiple drive components 622 to output power to multiple actuating plates 621 located between the battery channel 632 and the drive components 622 in a one-to-one correspondence. For example, there are three receiving parts 611, three actuating plates 621, and three corresponding drive components 622 between the drive components 622 and the rejection channel 630. When any battery in any of the three receiving parts 611 is a defective battery, the defective battery can be rejected by cooperating with the corresponding drive component 622 and the actuating plate 621.

[0112] Furthermore, by making the angular interval between adjacent driving members 622 consistent with the angular interval between adjacent receiving parts 611, the driving accuracy of the driving member 622 can be improved, so that the driving member 622 can accurately push the corresponding toggle plate 621 to remove the battery in the corresponding receiving part 611.

[0113] Therefore, on the one hand, it can realize multi-channel independent rejection of defective batteries, which can improve rejection accuracy and reliability, reduce the probability of battery tipping, and thus improve safety. On the other hand, it can simultaneously reject multiple defective batteries, so that when multiple consecutive defective batteries appear on the transition plate 610, they can also be accurately rejected, reducing the probability of failure to reject them.

[0114] like Figure 8 and Figure 9 As shown, according to some embodiments of this application, the toggle plate 621 is rotatably disposed on the transition disk 610 and is adapted to toggle the battery radially.

[0115] Specifically, the toggle plate 621 is set on the transition plate 610. The toggle plate 621 can be located on the axial direction of the transition plate 610 and can rotate relative to the transition plate 610 so that one end of the toggle plate 621 can move radially away from the transition plate 610 relative to the transition plate 610 to toggle the faulty battery to move radially away from the receiving part 611.

[0116] In this way, the battery can be removed radially from the receiving part 611, which reduces the probability of interference between the receiving part 611 and the battery during the removal process. This makes it easier for the battery to detach from the transition plate 610, reducing the difficulty of removal and also reducing the probability of the battery rotating or tipping during the detachment process, thereby improving safety.

[0117] like Figure 9As shown, according to some embodiments of this application, the toggle plate 621 is rotatably disposed on the radially inner side of the receiving portion 611 via a pivot 6213 to toggle the battery radially outward.

[0118] Specifically, the actuating plate 621 is disposed on the tangent of a virtual circle coaxial with the transition disk 610. The outer diameter of the virtual circle is smaller than the outer diameter of the transition disk 610. One end of the actuating plate 621 is rotatably disposed on the transition disk 610 via a rotating shaft 6213, and the other end can be selectively rotated relative to the transition disk 610, so that the actuating plate 621 can move the battery radially out of the receiving part 611, reducing the difficulty of rejection and improving the smoothness of the movement of the rejected battery.

[0119] like Figure 9 As shown, according to some embodiments of this application, the actuating plate 621 includes: a first actuating plate 6211 and a second actuating plate 6212, the first actuating plate 6211 and the second actuating plate 6212 are disposed on both sides of the transition plate 610 in the axial direction and connected to the same rotating shaft 6213.

[0120] Specifically, the first actuating plate 6211 and the second actuating plate 6212 are arranged opposite each other in the axial direction of the transition plate 610, and the first actuating plate 6211 and the second actuating plate 6212 are pivotally connected to the transition plate 610 through the same rotating shaft 6213, so that the first actuating plate 6211 and the second actuating plate 6212 can synchronously push the battery to move radially out of the receiving part 611, so that the force distribution when the battery is rejected is more uniform, reducing the probability of the battery tipping over, thereby improving the safety and reliability of the battery rejection device 600.

[0121] It should be noted that in some embodiments, a safety device may be provided downstream of the battery rejection device 600. When the defective condition of the battery is characterized by high temperature, combustion or other conditions, the defective battery can be directly rejected by the battery rejection device 600 and placed into the safety device. The safety device may be constructed as a sandbox or other safety structure.

[0122] According to some embodiments of this application, the rejection component 620 further includes a reset member disposed on the rotating shaft 6213 and used to drive the toggle plate 621 to reset.

[0123] The reset member can be constructed as an elastic element such as a torsion spring. The reset member is suitable for keeping the toggle plate 621 in the avoidance position of the battery in the avoidance receiving part 611 under the action of its own elastic force. After the defective battery rejection action is completed, it can also be reset to the avoidance position under the action of the elastic force of the reset member.

[0124] In this way, the reset structure of the first actuating plate 6211 and the second actuating plate 6212 is simpler, which can simplify the structure of the rejection section and reduce the cost of the battery rejection device 600.

[0125] The driving member 622 can be constructed as either a driving cylinder or a driving oil cylinder, and the part of the driving member 622 that extends out and is used to push the toggle plate 621 can be formed with a driving protrusion 6221. The surface of the driving protrusion 6221 facing the toggle plate 621 is constructed as an arc surface to improve driving stability.

[0126] Furthermore, the battery rejection device 600 may also include a cam divider 700. Of course, the battery rejection device 600 may also mesh with the conveying device 110, etc., and the cam divider 700 can be used to drive one of the conveying device 110 and the transition plate 610.

[0127] The cam divider 700 is used to drive the transition disk 610 to rotate according to the interval angle between adjacent multiple receiving parts 611, and the number of adjacent multiple receiving parts 611 is the same as the number of driving members 622.

[0128] Therefore, by setting a cam divider 700, which is connected to the transition disk 610, such as the cam divider 700 directly engaging with the transition disk 610, or the cam divider 700 engaging with the first turntable 111, and the first turntable 111 engaging with the transition disk 610, indirect transmission between the cam divider 700 and the transition disk 610 is achieved. This allows the rotation of the transition disk 610 to proceed and stop according to the drive angle of the cam divider 700 and in a time-proportional manner. Each time the disk stops, the rejection assembly 620 selectively rejects the receiving part 611 located between the rejection channel 630 and the drive member 622.

[0129] It is understood that the cam divider 700 is powered to the transition disk 610, and the number of receiving parts 611 located between the rejection channel 630 and the drive member 622 is at least two. During each travel time on the transition disk 610, multiple batteries can be sequentially received to the multiple receiving parts 611 of the transition disk 610. The multiple batteries received during each travel time are defined as a group of batteries, and during each stop time, one or more batteries in the group of batteries can be rejected.

[0130] In this way, by setting the cam divider 700 to realize the movement and stopping of the transition plate 610, and cooperating with the rejection component 620 to selectively reject at least two batteries on the transition plate 610, on the one hand, the matching accuracy requirement of the rejection component 620 can be reduced, and defective batteries can be rejected more accurately, reducing the probability of false rejection due to mismatch of rejection timing. On the other hand, batteries can be selectively rejected in groups, and even if multiple consecutive defective batteries appear upstream, they can be accurately rejected, reducing the probability of not being rejected, thereby improving the reliability and stability of the battery rejection device 600.

[0131] like Figure 7 and Figure 10 As shown, according to some embodiments of this application, the rejection channel 630 has a plurality of guide bars 631, and adjacent guide bars 631 define a battery channel 632, each battery channel 632 being used for the flow of defective batteries and the positioning member 800.

[0132] Specifically, multiple guide bars 631 are formed on the rejection channel 630 to define multiple battery channels 632, and each battery channel 632 can be used for the flow of defective batteries.

[0133] In this way, by setting up multiple battery channels 632, and the number of battery channels 632 being consistent with the number of receiving parts 611 that can simultaneously reject defective batteries, defective batteries rejected by different receiving parts 611 can enter different battery channels 632. The guide strip 631 guides and limits the movement of the batteries, which can reduce the probability of collisions between multiple batteries when there are multiple batteries on the rejection channel 630, and can also reduce the probability of batteries tipping over, thereby further improving rejection stability and safety.

[0134] It should be noted that the rejection channel 630 can be constructed as a conveyor belt, and a guide bar 631 is provided above the conveyor belt so that the battery can move along the rejection channel 630 from one end near the transition plate 610 to the other end away from the transition plate 610 within the battery channel 632.

[0135] like Figure 10 As shown, according to some embodiments of this application, the guide bar 631 has a cross-sectional area that gradually decreases in the direction toward the transition disk 610, near one end of the transition disk 610.

[0136] Specifically, a guide portion 6311 may be provided at one end of the guide bar 631 adjacent to the transition disk 610. The guide portion 6311 of the guide bar 631 is configured such that the cross-sectional area gradually decreases in the direction adjacent to the transition disk 610, so that the ends of two adjacent guide bars 631 adjacent to the transition disk 610 can form a flared structure, so as to guide the battery into the battery channel 632, reduce the difficulty of the battery entering the battery channel 632, and effectively guide the battery to reduce the probability of the battery tipping over.

[0137] Of course, it is understandable that the guide bar 631 can be fixed to the frame of the battery rejection device 600 by the fixing rod 633. The fixing rod 633 can adjust the position of the guide bar 631 on the rejection channel 630 so that the position between adjacent guide bars 631 can be adjusted, thereby realizing the width adjustment of the battery channel 632 to adapt to the rejection of batteries of different specifications and sizes.

[0138] like Figure 7 As shown, according to some embodiments of this application, the battery rejection device 600 further includes a hopper 640, which is located at one end of the rejection channel 630 away from the transition plate 610 and is used to accommodate batteries rejected to the rejection channel 630.

[0139] In this way, the batteries transferred out of the battery rejection device 600 through the rejection channel 630 can be stored in the hopper 640. The hopper 640 can be a relatively isolated hygienic and safe space, which can not only improve safety, but also avoid internal contamination of the batteries stored in the hopper 640, and facilitate the secondary use of defective batteries.

[0140] Combination Figure 7 and Figure 10 As shown, according to some embodiments of this application, the hopper 640 has a feed door 641 and a discharge door 642. The feed door 641 and the discharge door 642 are arranged opposite to each other. The feed door 641 is located at one end of the hopper 640 adjacent to the rejection channel 630 and is adapted to be opened for feeding. The discharge door is located at one end of the hopper 640 away from the hopper 640 and is adapted to be opened for discharging.

[0141] Specifically, the feed door 641 and the discharge door 642 are arranged opposite to each other. The feed door is used to allow batteries on the rejection channel 630 to enter the hopper 640, while the discharge door 642 is used to transfer batteries located in the hopper 640. The discharge door 642 is arranged opposite to the feed door 641, that is, the discharge door 642 is located on the side of the hopper 640 away from the rejection channel 630, which can reduce the difficulty of retrieving batteries in the hopper 640 and improve the convenience of retrieval.

[0142] According to some embodiments of this application, the feed gate 641 and the discharge gate 642 are configured to open selectively.

[0143] In some embodiments, a linkage mechanism is provided between the feed door 641 and the discharge door 642. The linkage mechanism can be constructed as a lever structure, an interlocking structure, etc., to achieve that when the feed door 641 is opened, the discharge door 642 is locked, or when the discharge door 642 is opened, the feed door 641 is locked. In other embodiments, the feed door 641 and the discharge door 642 can be controlled by a controller. The controller is used to control the discharge door 642 drive structure to be de-energized and locked when the feed door 641 is opened, or the feed door 641 drive structure to be de-energized and locked when the discharge door 642 is opened, so as to achieve selective opening, thereby improving the safety of opening the discharge door 642 and retrieving the battery located in the hopper 640, and reducing the probability of foreign objects entering the space where the battery rejection device 600 is located through the hopper 640, thereby improving the reliability and stability of the battery rejection device 600.

[0144] It should be noted that the battery rejection device 600 is a downstream device of the battery processing device. Batteries processed by the battery processing device can be transferred to the battery rejection device 600 for rejection of defective batteries. The battery processing device can be a battery liquid injection device, a battery welding device, a battery casing device, etc. High-frequency lasers may be present in the battery processing device for battery welding or cleaning. The laser protection can be achieved by selectively opening either the feed door 641 or the discharge door 642, thereby improving safety.

[0145] like Figure 12 As shown, this application further proposes a method for rejecting batteries using a battery rejection device 600, the rejection method comprising:

[0146] This process takes over from the previous step and completes the processing of batteries and defective batteries.

[0147] Remove defective batteries; wherein, within a first set time period, processed batteries and defective batteries are accepted, and within a second set time period, defective batteries are removed.

[0148] Specifically, the battery that has been processed in the previous step can be a battery that has been injected with electrolyte by a battery injection device or a battery that has been cleaned by a battery injection hole cleaning device 100. The transition plate 610 can receive the processed battery and the defective battery that appears during the processing within a first set time and move it to be opposite to the rejection channel 630. The battery that the transition plate 610 receives in the receiving part 611 can be selectively rejected into the rejection channel by the drive member 622 within a second set time.

[0149] In this way, the rejection of defective batteries can be decoupled from the reception and transfer of batteries by the transition plate 610. The reception of batteries is carried out within a first set time, and the rejection of defective batteries is carried out within a second set time. During the second set time, the transition plate 610 stops rotating, which can improve the rejection accuracy and quality, and can realize the simultaneous rejection of multiple defective batteries in multiple channels, so as to solve the technical problem that existing rejection devices are difficult to reject multiple defective batteries at the same time.

[0150] This application proposes a battery production line, including: a battery processing device, a feeding turntable 300, and a battery rejection device 600. The battery processing device has a conveying device 110 and is used to process batteries. The feeding turntable 300 is connected to the conveying device 110 and is located downstream of the battery processing device. It is used to receive processed batteries and defective batteries. The transition plate 610 is connected to the conveying device 110 and is located downstream of the feeding turntable 300. It is used to reject defective batteries or transfer processed batteries.

[0151] For example, taking the battery filling hole cleaning device 100 as an example, the conveying device 110 is connected to the unloading turntable 300, and the unloading turntable 300 is connected to the transition plate 610, so that the cleaned batteries and defective batteries on the first turntable 111 in the conveying device 110 can be further transferred to the transition plate 610 through the unloading turntable 300. After the transition plate 610 receives the cleaned batteries and defective batteries, the driving member 622 moves the actuating plate 621 to push the positioning member 800 and defective batteries radially along the receiving part 611 to the rejection channel 630.

[0152] According to the battery production line of this application embodiment, the unloading turntable 300 is used to unload the processed batteries on the battery processing device. After unloading, the batteries can flow through the battery rejection device 600 and reject defective batteries. This can realize automated rejection and reduce the probability of incorrect rejection and failure to reject, thereby improving the reliability and safety of the battery production line.

[0153] It should be noted that when the batteries processed on the battery production line are charged batteries, the battery rejection device 600 of this application embodiment can effectively improve safety.

[0154] Furthermore, the battery production line also includes a loading line 400 and a unloading line 500. The loading line 400 is located upstream of the battery processing device and is used to supply the batteries to be processed and the positioning parts 800 to the battery processing device. The unloading line 500 is located downstream of the transition plate 610 and is used to receive the processed batteries and the positioning parts 800.

[0155] In other words, the feeding line 400 feeds batteries to the battery processing device. The batteries processed by the battery processing device and the defective batteries are transported to the transfer plate 610 through the unloading turntable 300. After the defective batteries are removed by the rejection component 620 in conjunction with the transfer plate 610, the processed batteries (i.e. qualified batteries) in the transfer plate 610 can be further transferred out of the battery production line through the unloading line 500.

[0156] The following describes the battery production line structure in detail, using the battery production line of this application embodiment as a battery cleaning line, the battery processing device as a cleaning device 100 for the battery injection hole, and the battery rejection device 600 located downstream of the cleaning device 100 and used to receive the cleaned batteries removed from the cleaning device 100 by the unloading turntable 300.

[0157] This application discloses a cleaning device 100 for battery filling holes. The cleaning device 100 includes a cleaning assembly 130, a conveying device 110, and a clamping assembly 120.

[0158] The cleaning components 130 are multiple and spaced apart along a first direction; the conveying device 110 runs along the first direction and is configured to run for a first set time to convey the battery to be cleaned and pause for a second set time so that the liquid inlet of the battery to be cleaned is cleaned by one of the cleaning components 130; multiple clamping components 120 are spaced apart along the first direction on the conveying device 110, and each clamping component 120 includes a clamp 124 and a release member 123. The clamp 124 is used to hold the battery to be cleaned, and the release member 123 can interact with the clamp 124 to separate the battery to be cleaned from the positioning member 800 within one of the first set times.

[0159] Specifically, the first direction is the rotation direction, which can be counterclockwise or clockwise. The conveying device 110 can rotate along the first direction. During the rotation, it can rotate for a first set time and stop rotating for a second set time. During the rotation within the first set time, batteries to be cleaned can be placed on some of the clamping assemblies 120. The clamping assemblies 120 with batteries to be cleaned can move toward the cleaning assembly 130 along the first direction. During the movement toward the cleaning assembly 130, the release member 123 can separate the batteries to be cleaned from the positioning member 800 (e.g., a cup holder). The release member 123 interacts with the clamp 124 so that after the release member 123 separates the batteries to be cleaned from the positioning member 800, the clamp 124 simultaneously clamps the batteries to be cleaned.

[0160] Furthermore, the clamped battery can be cleaned by passing through the cleaning assembly 130 and the conveying device 110 pausing for a second set time.

[0161] It should be noted that the conveying module can move and stop according to the time ratio of the first set time and the second set time. During the movement (within the first set time), the clamping assembly 120 can simultaneously realize the loading of the battery to be cleaned, the unloading of the battery to be cleaned, the separation of the battery to be cleaned from the positioning member 800 before it moves to the cleaning assembly 130, and the clamping of the battery to be cleaned. During the stop (within the second set time), the cleaning assembly 130 can clean the battery to be cleaned. During the loading of the battery to be cleaned, the separation of the battery to be cleaned from the positioning member 800 and the clamping of the battery to be cleaned can be completed simultaneously. During the unloading of the battery to be cleaned, the battery can be reset and released simultaneously.

[0162] In the existing technology, the battery cleaning equipment 100 has a linear layout. After the battery arrives at the cleaning position, it needs to be lifted and clamped by the clamp 124. These two auxiliary actions take a certain amount of time (e.g., 3 seconds). In other words, these two auxiliary actions occupy 3 seconds of the production cycle. During these 3 seconds, the laser of the cleaning component 130 is still on, which reduces the laser utilization rate, increases equipment cost, and the linear layout also increases space occupation.

[0163] It should be noted that separating the battery to be cleaned from the positioning component 800 within one of the first set time periods means that a loading and unloading process is performed once within each first time period. Multiple batteries to be cleaned can be loaded each time. After multiple batteries to be cleaned are loaded, they move synchronously toward the cleaning component 130. At this time, the batteries to be cleaned are clamped by the clamp 124. Other batteries to be cleaned have been loaded before the first set time period, but have not been cleaned. Therefore, other batteries to be cleaned are still in a state of separation from the positioning component 800 and being clamped, but this is not done within the first set time period. It may be done in the previous first set time period or an earlier first set time period.

[0164] According to the battery cleaning equipment 100 of the present application embodiment, during the process of conveying the battery to be cleaned by the conveying device 110, the clamping assembly 120 can couple the battery loading action with the auxiliary action before battery cleaning, and the battery unloading action with the auxiliary action after battery cleaning. This can reduce processing time, speed up production cycle, improve laser utilization, reduce cleaning costs, and improve production efficiency.

[0165] According to some embodiments of this application, the conveying device 110 cooperates with the clamp 124 and the release member 123 to move the release member 123 relative to the clamp 124 to separate the positioning member 800 from the battery to be cleaned, and the clamp 124 clamps the battery to be cleaned.

[0166] Specifically, during the rotation of the conveying device 110, the clamp 124 and the release member 123 can be driven synchronously so that the clamp 124 and the release member 123 interact. The contact member separates the battery to be cleaned from the positioning member 800 and facilitates the laser-guided positioning of the cleaning component 130. At the same time, the clamp 124 can tighten the battery to be cleaned to prevent the battery from moving during the subsequent cleaning process of the cleaning component 130, thereby improving the cleaning accuracy and cleaning effect. Meanwhile, the clamp component 120 can perform auxiliary actions before and after battery cleaning, all of which can be realized under the drive of the conveying device 110. This can also simplify the structure of the cleaning equipment 100, reduce costs, and improve the space occupied by the cleaning equipment 100.

[0167] like Figure 1 and Figure 2As shown, the conveying device includes a turret 112 and a first turntable 111. A plurality of clamping assemblies 120 are spaced apart on the first turntable 111 along a first direction. The turret 112 is sleeved on the first turntable 111. The turret 112 has a first cam groove 1121 and a second cam groove 1122. The first cam groove 1121 is used to drive the clamp 124, and the second cam groove 1122 is used to drive the release member 123.

[0168] Specifically, the first turntable 111 is provided with a plurality of clamping assemblies 120 at intervals in the first direction, the turret 112 is sleeved on the first turntable 111, the first turntable 111 can rotate relative to the turret 112, and the turret 112 has a first cam groove 1121 and a second cam groove 1122. The release member 123 can contact and drive the first cam groove 1121, and the clamp 124 can contact and drive the second cam groove 1122. The first turntable 111 is adapted to drive the clamping assemblies 120 to rotate in the first direction, so that the first cam groove 1121 and the second cam groove 1122 are respectively used to drive the clamp 124 and the release member 123 to move.

[0169] Specifically, the first turntable 111 can drive the clamp assembly 120 located thereon to rotate. The release member 123 and the clamp 124 on each clamp assembly 120 are respectively located in the first cam groove 1121 and the second cam groove 1122. The first cam groove 1121 can limit the movement trajectory of the release member 123, and the second cam groove 1122 can limit the movement trajectory of the clamp 124, so that the release member 123 can further drive the battery to separate or reset from the positioning member 800 under the drive of the first cam groove 1121, and the clamp 124 can clamp or release the battery under the drive of the second cam groove 1122.

[0170] It should be noted that the first cam groove 1121 and the second cam groove 1122 are used to drive the movement of the clamp 124 and the release member 123, respectively, including: driving the battery away from or towards the positioning member 800, and driving the clamp 124 to clamp or release the battery.

[0171] Understandably, in combination Figure 3 As shown, the first turntable 111 can drive the clamp assembly 120 to move in the first direction. During the rotation of the clamp assembly 120 driven by the first turntable 111, at least a portion of the release member 123 can slide in the first cam groove 1121, and at least a portion of the clamp 124 can slide in the second cam groove 1122, so that within a first set time, the release member 123 can drive the battery away from the positioning member 800 (e.g., lift), and the clamp 124 can clamp the battery. After the battery cleaning is completed, the clamp 124 can release the battery, and the release member 123 can reset, so that the battery is reset to the positioning member 800.

[0172] It should be noted that the clamp assembly 120 is provided with a positioning cover plate 125, that is, the clamp assembly 120 also includes: positioning cover plate 125, the positioning cover plate 125 is connected to the mounting plate 121, the release member 123 is adapted to drive the battery to be cleaned to detach from the positioning member 800 and push against the positioning cover plate 125, and the side of the positioning cover plate 125 away from the battery holder 122 is opposite to the cleaning assembly 130.

[0173] In other words, the positioning cover 125 is used to position the battery. The cleaning assembly 130 can use the positioning cover 125 for visual guidance and, after positioning the cleaning area of ​​the battery to be cleaned, clean the battery. In some embodiments, the release member 123 can be used to move the battery toward the positioning cover 125 and disengage it from the positioning member 800. In other embodiments, the release member 123 can be equivalent to other actuating parts and configured so that the positioning cover 125 moves toward the battery. All of these methods can achieve the same positioning of the battery and facilitate the visual positioning and cleaning guidance of the cleaning assembly 130 to improve the cleaning accuracy. Further details will not be provided here.

[0174] In other words, the first cam groove 1121 and the second cam groove 1122 form a double-layer cam groove structure on the turret 112. Through the cam trajectory cooperation of the two cam grooves, the battery can be clamped and fixed as well as released, the battery can be lifted and lowered (or the positioning cover 125 can be pressed down and lifted). The cleaning component 130 realizes visual guidance and laser cleaning.

[0175] Therefore, through the cooperation of the first turntable 111, the turret 112 and the clamping assembly 120, the battery loading action is coupled with the pre-cleaning auxiliary action, and the battery unloading action is coupled with the post-cleaning auxiliary action, so as to simplify the production cycle and improve production efficiency. At the same time, the cam turret 112 layout can improve the space occupation of the cleaning equipment 100, reduce the space requirements of the factory, and reduce the layout cost.

[0176] like Figure 3 and Figure 4 As shown, the clamp assembly 120 also includes a mounting plate 121 and a battery holder 122, a positioning member 800 is detachably disposed on the battery holder 122, and a clamp 124 and a release member 123 are movably disposed on both sides of the battery holder 122.

[0177] The clamping assembly 120 includes a mounting plate 121, a battery holder 122, a release member 123, a clamp 124, and a positioning cover plate 125. The mounting plate 121 is connected to the first turntable 111. The battery holder 122 is disposed on the mounting plate 121 and is used to place the battery and the positioning member 800. The clamp 124 and the release member 123 are slidably disposed on the mounting plate 121. The positioning cover plate 125 is disposed opposite to the battery holder 122. The clamp 124 is located between the positioning cover plate 125 and the battery holder 122. The release member 123 is located on the side of the battery holder 122 away from the positioning cover plate 125 and is used to drive the battery toward or away from the positioning cover plate 125. The cleaning assembly 130 is adapted to cooperate with the positioning cover plate 125 to position and clean the battery.

[0178] Specifically, the clamp assembly 120 includes a release member 123, a battery holder 122, a clamp 124, and a positioning cover 125, which are sequentially arranged along the axial direction of the battery on the mounting plate 121. The battery can be magnetically fixed in the battery holder 122 by the positioning member 800, and the release member 123 can push the battery out of the positioning member 800. After the battery is extended, it can be pushed against the positioning cover 125 so that the cleaning assembly 130 can position and clean the liquid injection hole area of ​​the battery. At the same time as the battery is extended, the clamp 124 can clamp the battery to prevent the battery from moving during the positioning and cleaning process, thereby improving the positioning accuracy and cleaning quality.

[0179] Thus, the mounting plate 121 is connected to the first turntable 111, and the battery is detachably mounted on the battery holder 122 through the positioning member 800. It can be lifted and clamped by the clamp 124 and the release member 123, which can further improve the cleaning accuracy and cleaning effect, and simplify the structure of the cleaning equipment 100 and reduce the cost of the cleaning equipment 100.

[0180] like Figure 4 As shown, according to some embodiments of this application, the release member 123 includes: a first slider 1231, a first guide rail 1232, and a release member body 1233. The release member body 1233 is disposed on the first slider 1231, the first guide rail 1232 is disposed on the mounting plate 121, and the first slider 1231 is connected to the first cam groove 1121 to drive the first slider 1231 and the release member body 1233 to move along a first direction.

[0181] Specifically, the first guide rail 1232 extends along a first direction, and the first slider 1231 is disposed on the first guide rail 1232 so that the first slider 1231 can move relative to the first guide rail 1232 along the battery axis. The release body 1233 is disposed on the first slider 1231. The first slider 1231 is slidably disposed in the first cam groove 1121 so that during the rotation of the first turntable 111, the cam trajectory of the first cam groove 1121 drives the first slider 1231 to move relative to the first guide rail 1232. Thus, during loading or unloading, the release body 1233 can be in the lower position. During the cleaning process, the release body 1233 can be in the lifting position to lift the battery from the positioning member 800 and push it against the positioning cover plate 125 so that the battery's liquid injection hole area can approach the positioning cover plate 125, thereby facilitating visual guidance of the cleaning assembly 130 and improving the cleaning accuracy and cleaning quality of the cleaning assembly 130.

[0182] Therefore, through the cooperation of the first slider 1231 and the first cam groove 1121, the release body 1233 can move according to the cam trajectory of the first cam groove 1121 to realize the lifting or lowering of the battery. The first turntable 111 cooperates with the turret 112 to drive the first slider 1231. The lifting and lowering of the release part 123 and the rotation of the first turntable 111 are more synchronized, and the cleaning equipment 100 has higher cleaning accuracy and better cleaning effect.

[0183] Combination Figure 4 As shown, according to some embodiments of this application, the clamp 124 includes: two opposing gripper portions 1241 and a first drive plate 1242. The gripper portions 1241 are slidably disposed on the mounting plate 121. The first drive plate 1242 is connected to the second cam groove 1122 and is slidably disposed on the mounting plate 121. The first drive plate 1242 cooperates with the gripper portions 1241 to drive the gripper portions 1241 to move.

[0184] Based on this, the clamp 124 of this application includes a gripper portion 1241 and a first drive plate 1242. The first drive plate 1242 can be connected to the second cam groove 1122 to drive the first drive plate 1242 to move along the axial direction of the battery. The contact end of the first drive plate 1242 and the gripper portion 1241 is constructed as a wedge-shaped fit structure. The gripper portion 1241 is slidably disposed on the mounting plate 121 so that the first drive plate 1242 pushes the gripper portion 1241 to move towards or away from each other in the radial direction of the battery, thereby clamping or releasing the battery. The two gripper portions 1241 can be constructed to be slidably disposed on the mounting plate 121 and can be kept in a released state by means of an elastic member. During the process of the first drive plate 1242 pushing the gripper portion 1241, the elastic force can be overcome so that the two gripper portions 1241 can move towards each other.

[0185] Of course, a drive groove can also be provided on the first drive plate 1242, and a drive block that cooperates with the drive groove can be provided on the corresponding gripper part 1241. The drive groove is constructed as an inclined groove with an angle to the battery axis, and the distance between the upper ends of the two inclined grooves corresponding to the two gripper parts 1241 is less than the distance between the lower ends, so that when the first drive plate 1242 slides down, it pushes the two gripper parts 1241 to move towards each other.

[0186] In this way, by setting up the clamp 124 and enabling the gripper portion 1241 of the clamp 124 to switch between the clamping position and the releasing position under the drive of the second cam groove 1122, the battery clamping action can be synchronized with the battery lifting action, so as to further reduce the production cycle and improve production efficiency.

[0187] According to some embodiments of this application, the gripper portion 1241 includes: a gripper body, a second slider, a second guide rail, and a second drive plate. The second drive plate is connected to the first drive plate 1242 and is slidably disposed on the mounting plate 121. The second guide rail is disposed on the second drive plate, the gripper body is disposed on the second slider, and the second slider and the second guide rail are slidably engaged.

[0188] It should be noted that common battery clamping methods are magnetic clamping or vacuum adsorption positioning. Due to the magnetic force of the magnet or the suction force of the vacuum nozzle, the battery is relatively easy to fall off. Furthermore, when the battery is lifted by the release part 123, there is a certain probability that the battery casing will be scratched by the clamp 124.

[0189] In this application, the first drive plate 1242 is connected to the second drive plate. For example, the first drive plate 1242 and the second drive plate achieve contact power transmission through a wedge structure to push the second drive plate to move radially along the battery. Alternatively, the second drive plate is provided with a drive block, and the first drive plate 1242 is provided with a drive groove. The drive groove is constructed as an inclined groove, and the drive block is slidably disposed in the drive groove to achieve power transmission. Furthermore, the second drive plate is provided with a second guide rail, and a slidable second slider is provided on the second guide rail. The second slider is provided with a gripper body, so that when the gripper body clamps the battery, it can move along with the release member 123 when the battery is pushed to move, thereby reducing the relative displacement between the gripper body and the battery in the clamped state, thereby reducing battery scratches caused by the gripper body, improving cleaning quality, and reducing the probability of battery damage.

[0190] It is understood that the battery casing may be coated with insulating material, and if the gripper body scratches the battery, it may lead to a dangerous situation for the charged battery. This application can reduce the probability of scratching. In the embodiment of the battery cleaning device 100 of this application for cleaning charged batteries, it can also improve the cleaning safety and reliability.

[0191] like Figure 2 As shown, according to some embodiments of this application, the cleaning equipment 100 further includes: a cam divider 700, a conveying device 110 connected to the cam divider 700, a clamping assembly 120 divided into a plurality of clamping groups 101 in a first direction, each clamping group 101 containing at least two clamping assemblies 120, the angular interval between two adjacent clamping groups 101 being a first included angle, and the cam divider 700 being used to drive the conveying device 110 to move along the first direction according to the first included angle.

[0192] Specifically, the cam divider 700 and the first turntable 111 can be configured as a gear meshing transmission structure. The cam divider 700 itself drives the first turntable 111 to rotate through an incomplete gear, so that the first turntable 111 can achieve proportional control between rotation and stop according to the drive angle of the cam divider 700. For example, when the cam divider 700 rotates one revolution, it drives the first turntable 111 to rotate one-third revolution, that is, the travel-stop ratio is 3:3. During the travel, the loading of the battery to be cleaned, the unloading of the battery to be cleaned, the auxiliary actions before cleaning the battery to be cleaned, and the auxiliary actions before unloading the battery to be cleaned can be realized simultaneously.

[0193] In this way, the battery can have a travel time (first set time) and a stop time (second set time) in the first turntable 111. Processing can be carried out during the stop time, that is, intermittent processing can be realized. At the same time, the proportion of battery cleaning time can be greater than the proportion of processing preparation time, so as to improve production efficiency, improve laser utilization, and reduce costs.

[0194] For example, if the drive angle of the cam divider 700 is 120°, then the ratio of travel time to stop time is 1:2. If it takes 1 second to drive the first turntable 111 to rotate 120°, then the stop time is 2 seconds, which provides more time for battery cleaning and higher laser utilization.

[0195] It should be noted that the cam divider 700 drives the first turntable 111 to move, so that the first divider moves and stops according to the travel time and the stop time. During each travel time, multiple batteries can be loaded, that is, multiple batteries can be loaded each time.

[0196] According to some embodiments of this application, the number of cleaning components 130 is the same as the number of clamping components 120 in the clamping group 101, and in the first direction, each clamping group 101 is provided with a corresponding cleaning component 130, or the last clamping group 101 is not provided with a corresponding cleaning component 130.

[0197] According to some embodiments of this application, the number of cleaning components 130 is the same as the number of clamping components 120 in the clamping group 101, and in the first direction, each clamping group 101 is provided with a corresponding cleaning component 130, or each clamping group 101 is provided with a corresponding cleaning component 130, and the last clamping group 101 is not provided with a corresponding cleaning component 130.

[0198] In other words, if there are two fixture components 120 in fixture group 101, then there are also two cleaning components 130; if there are three fixture components 120, then there are also three cleaning components 130.

[0199] In some embodiments, such as Figure 6 As shown, each fixture group 101 is provided with a corresponding cleaning component 130, and the last fixture group 101 is not provided with a corresponding cleaning component 130.

[0200] See Figure 6 For example, each clamp group 101 has three clamp components 120. In the first direction, the first turntable 111 is divided into four regions corresponding to the included angles of adjacent clamp groups 101, which are defined as the head region, the first middle region, the second middle region, and the tail region, respectively. Within each first preset time period, one region of each clamp group 101 moves to the next adjacent region in the first direction. The head region, the first middle region, and the second middle region are each provided with a cleaning component 130. During the flow process, the first turntable 111 rotates 90° at each angle interval between adjacent clamp groups 101, so that the three clamps to be cleaned can be moved to the next adjacent region. Taking a battery as an example, the fixture group 101 containing three batteries to be cleaned first enters the first end area. The cleaning component 130 in the first end area can clean one of the three batteries, such as the first or the third. Then the whole group enters the first intermediate area. The cleaning component 130 in the first intermediate area can clean the second of the three batteries. Then the whole group enters the second intermediate area. The cleaning component 130 in the second intermediate area can clean the third or the first of the three batteries. Finally, the whole group enters the tail end area, and all three batteries to be cleaned in the tail end area are cleaned and can be unloaded and loaded in the tail end area.

[0201] In other embodiments, such as Figure 11 As shown, each fixture group 101 is equipped with a corresponding cleaning component 130.

[0202] See Figure 11For example, each clamp group 101 has three clamping components 120. In the first direction, the first turntable 111 is divided into three regions corresponding to the included angles of adjacent clamp groups 101, defined as the head region, middle region, and tail region, respectively. Within each first preset time period, one region of each clamp group 101 moves to the next adjacent region in the first direction. A cleaning component 130 is correspondingly provided in each of the head region, middle region, and tail region. During the flow process, the first turntable 111 rotates the angular interval between adjacent clamp groups 101 each time, i.e. Rotate 120°. Taking three batteries to be cleaned as an example, the fixture group 101 containing the three batteries to be cleaned first enters the first area. The cleaning component 130 in the first area can clean one of the three batteries to be cleaned, such as the first or the third. Then the whole group enters the middle area. The cleaning component 130 in the middle area can clean the second of the three batteries to be cleaned. Then the whole group enters the tail area. The cleaning component 130 in the tail area can clean the third or the first of the three batteries to be cleaned, and loading and unloading can be performed in the tail area.

[0203] Therefore, each fixture group 101 can achieve the cleaning of all the batteries to be cleaned within the group after multiple first predetermined times and multiple second predetermined times. During the overall flow of the conveying device 110, multiple batteries to be cleaned can be cleaned simultaneously, which can further improve the cleaning efficiency of the cleaning equipment 100.

[0204] Combination Figure 3 , Figure 6 as well as Figure 11 As shown, the first cam groove 1121 has a first trajectory segment and a second trajectory segment. The height difference between the second trajectory segment and the first trajectory segment is consistent with the movement stroke of the release member 123, and the extension angle of the first trajectory segment is less than or equal to the first included angle. The second cam groove 1122 has a third trajectory segment and a fourth trajectory segment. The height difference between the fourth trajectory segment and the third trajectory segment is consistent with the movement stroke of the clamp 124, and the extension angle of the third trajectory segment is less than or equal to the first included angle.

[0205] Specifically, the turret 112 has a first cam groove 1121 and a second cam groove 1122 in an annular shape. At least a portion of the release member 123 extends into the first cam groove 1121, and at least a portion of the clamp 124 extends into the second cam groove 1122. The height difference between the first track segment and the second track segment can drive the release member 123 to move along the battery axis. For example, from the first track segment to the second track segment, the release member 123 rises, and from the second track segment to the first track segment, the release member 123 falls. The height difference between the third track segment and the fourth track segment can drive the clamp 124 to clamp or release the battery. For example, from the third track segment to the fourth track segment, the clamp 124 clamps the battery, and from the fourth track segment to the third track segment, the clamp 124 releases the battery.

[0206] It should be noted that, see Figure 6 As shown, Figure 6 In the illustrated embodiment, the extension angles of the first and third trajectory segments are equal to the first included angle. That is, while the clamp assembly 101 in the second intermediate region moves to the tail end region, the clamp 124 releases the battery and the release component 123 descends. See [reference needed]. Figure 11 As shown, Figure 11 In the embodiment shown, the extension angle of the first trajectory segment and the third trajectory segment is less than the first included angle, that is, when entering the clamp group 101 in the tail end region, the clamp 124 of the clamp assembly 120 where the battery to be cleaned is located is still in the clamping state, and the release member 123 is still in the rising position. After the cleaning of the battery is completed, both the clamp 124 and the release member 123 of the clamp assembly 120 where the battery is located are released.

[0207] Therefore, the extension angles of the first and third trajectory segments can be made more reasonable. The clamping group 101 containing the uncleaned battery can always maintain the battery in a clamped state during the overall movement and stopping process, thereby improving the working stability and reliability of the cleaning equipment 100.

[0208] Combination Figure 6 and Figure 11 As shown, the multiple clamping components 120 within each clamping group 101 are defined as the first clamp to the Nth clamp. In the first direction, the cleaning component 130 corresponding to the previous clamping group 101 is either adjacent to or far away from the first clamping component 130 corresponding to the next clamping group 101.

[0209] Among them, such as Figure 6 As shown, cleaning components 130 are provided in the first end area, the first intermediate area, and the second intermediate area, as follows: Figure 11 As shown, cleaning components 130 are provided in the first, middle and last regions, and the number of clamping components 120 in each clamping group 101 is the same as the total number of cleaning components 130.

[0210] Specifically, the number of clamp components 120 in each clamp group 101 is equal to the total number of cleaning components 130, so that multiple batteries in a group can be cleaned sequentially as they flow through multiple areas. Each cleaning position can clean one of the batteries in a group, and all batteries in the group can be cleaned. This can improve cleaning efficiency, and there can be intervals between adjacent cleaning components 130, which can also reduce the space requirements for laying out the cleaning components 130 and reduce the difficulty of layout.

[0211] Furthermore, such as Figure 6 As shown, in some embodiments, each clamp group 101 includes a first clamp, a second clamp, and a third clamp arranged sequentially in a first direction, corresponding to three cleaning components 130. The cleaning components 130 corresponding to the previous clamp group 101 are arranged with the first clamp in the adjacent group being opposite to the cleaning components 130 in the next clamp group 101. That is, the first clamp of the clamp group 101 located in the first end region is opposite to the cleaning components 130, while the second clamp of the clamp group 101 in the first middle region is opposite to the cleaning components 130, and the third clamp of the clamp group 101 in the second middle region is opposite to the cleaning components 130.

[0212] like Figure 11 As shown, in some other embodiments, each clamp group 101 includes a first clamp, a second clamp, and a third clamp arranged sequentially in a first direction, corresponding to three cleaning components 130. The cleaning component 130 corresponding to the first clamp group 101 is located further away from the first clamp in the group than the cleaning component 130 corresponding to the second clamp group 101. That is, the third clamp of the clamp group 101 in the first end region is opposite to the cleaning component 130, the second clamp of the clamp group 101 in the middle region is opposite to the cleaning component 130, and the first clamp of the clamp group 101 in the tail end region is opposite to the cleaning component 130.

[0213] In this way, by reasonably setting the relative positions of multiple cleaning components 130 on different areas of the first turntable 111 and the corresponding clamp groups 101, multiple batteries in each group can be cleaned after passing through multiple areas of the first turntable 111. This not only makes the spacing between the multiple cleaning components 130 more reasonable, reduces the difficulty of arrangement, reduces the probability of mutual interference, and improves the cleaning accuracy, but also makes reasonable use of the space around the first turntable 111, so that the overall layout of the battery cleaning equipment 100 is more compact and can further improve the space occupation.

[0214] like Figure 5 As shown, according to some embodiments of this application, the cleaning assembly 130 includes a galvanometer module 131 and a camera module 134, with the optical paths of the galvanometer module 131 and the camera module 134 being coaxial.

[0215] Specifically, the optical paths of the camera module 134 and the galvanometer module 131 are coaxial, enabling the camera module 134 to provide coaxial visual guidance to the galvanometer module 131. That is, after the camera module 134 captures the position of the injection hole, the galvanometer module 131 can directly perform laser cleaning at the position captured by the camera module 134, so as to accurately determine the location of the injection hole area through visual guidance and further perform laser cleaning.

[0216] It should be noted that the coaxial vision guidance is performed after the positioning cover plate 125 is pressed down. First, the camera module 134 takes a picture and captures the position of the injection hole. Then, the galvanometer module 131 performs laser cleaning in the original position.

[0217] In this way, on the one hand, laser cleaning is achieved through coaxial vision guidance. After the position of the injection hole is captured by taking a picture, the galvanometer module 131 and the battery do not need to be moved, which can reduce the movement error caused by the movement of the cleaning component 130, thereby improving the laser cleaning accuracy and effect. On the other hand, during the vision guidance process, not only can the position that needs to be laser cleaned be determined, but also the incoming material inspection (such as whether there are glue nails, whether there is electrolyte dirt, etc.) can be realized, and the requirements for the mechanical precision of the fixture 124 and the consistency of the incoming battery can be reduced.

[0218] According to some embodiments of this application, the optical path of the cleaning component 130 is coaxial with the positioning cover plate 125, and the positioning cover plate 125 is provided with a baffle to blow away the battery during the cleaning process of the galvanometer module.

[0219] It should be noted that during the laser cleaning process, a large amount of mixed dust consisting of electrolyte and shell material debris will be generated. Therefore, a suction structure can be set on the cleaning equipment 100 to suck up the mixed dust in the area of ​​the cleaning equipment 100, which can improve the cleaning quality and enhance the sealing effect of the injection hole.

[0220] It is understandable that, due to the size of the battery holder 122, the suction structure cannot directly remove all the dust. Correspondingly, a baffle can be set on the positioning cover 125 to generate turbulence, which can further improve the suction effect.

[0221] For example, the spoiler can be constructed as an annular air duct, a spoiler, or other structures.

[0222] like Figure 1As shown, the cleaning equipment according to the embodiment of this application further includes: a loading turntable 200 and a unloading turntable 300. The loading turntable 200 and the unloading turntable 300 are both located on the periphery of the first turntable 111 and are tangent to the first turntable 111. The loading turntable 200 and the unloading turntable 300 are both engaged and driven with the first turntable 111. The loading turntable 200 is used to supply the batteries to be cleaned to the first turntable 111, and the unloading turntable 300 is used to receive the cleaned batteries and defective batteries on the first turntable 111.

[0223] Specifically, the loading turntable 200 is located upstream of the conveying device 110 and is used to load the batteries to be cleaned onto the first turntable 111, while the unloading turntable 300 is located downstream of the conveying device 110 and is used to unload the cleaned batteries and defective batteries from the first turntable 111.

[0224] Furthermore, by enabling the first turntable 111, the feeding turntable 200, and the unloading turntable 300 to engage synchronously, the synchronization of the first turntable 111, the feeding turntable 200, and the unloading turntable 300 can be improved, thereby enhancing the cleaning reliability and stability of the cleaning equipment. At the same time, the feeding turntable 200 and the unloading turntable 300 can also stop and start according to the first and second set times of the conveying device 110, which can also improve the feeding accuracy and unloading accuracy respectively, reduce the probability of the battery tipping over during the feeding and unloading process, and improve the safety and reliability of the cleaning equipment 100.

[0225] In other words, it can not only improve cleaning efficiency and reduce cleaning costs, but also improve the synchronization between various devices and components in the cleaning equipment by the meshing and transmission of the first turntable 111, the feeding turntable 200 and the unloading turntable 300, resulting in higher cleaning accuracy and quality.

[0226] like Figure 1 As shown, according to some embodiments of this application, the cleaning equipment further includes: a feeding line 400, the feeding output end of the feeding line 400 is disposed adjacent to the feeding turntable 200, and a transition ratchet 410 is disposed between the two.

[0227] Therefore, the feeding line 400 can supply the batteries to be cleaned, improving the automation level of the cleaning equipment 100. Furthermore, the ratchet 410 can guide the batteries, reducing the probability of jamming and improving the reliability and stability of the cleaning equipment 100.

[0228] exist Figure 1 In the embodiments shown, according to some embodiments of this application, a first camera module 420 and a barcode scanner are provided near the feeding turntable 200. The first camera module 420 determines whether the battery has a sealing nail, and the barcode scanner reads the battery information.

[0229] Therefore, the presence or absence of adhesive nails in the incoming battery can be identified by the first camera module 420, and the electronic tag on the positioning component 800 can be scanned by the barcode scanner to mark the position of the battery without adhesive nails. This prevents the subsequent cleaning equipment 100 from cleaning the marked batteries, thereby improving the cleaning quality and achieving intelligent control. It also avoids cleaning batteries without adhesive nails and improves safety.

[0230] See Figure 1 According to some embodiments of this application, the cleaning equipment further includes: a feeding line 500, wherein the feeding input end of the feeding line 500 is disposed adjacent to the feeding turntable 300.

[0231] Therefore, the unloading line 500 can promptly transfer the cleaned batteries out of the cleaning equipment 100, improving the level of automation, preventing battery accumulation within the cleaning equipment 100, and further improving processing efficiency.

[0232] According to some embodiments of this application, a second camera module 510 is provided near the feeding turntable 300, which is used to detect the battery after cleaning.

[0233] In this way, the second camera module 510 acquires information about the batteries on the unloading turntable 300, checks the cleaning results, detects the position of the uncleaned batteries and the cleaning offset of each battery, so as to further identify the battery cleaning accuracy.

[0234] Combination Figure 1 and Figure 7 As shown, according to some embodiments of this application, a battery rejection device 600 is also provided between the unloading line 500 and the unloading turntable 300. The battery rejection device 600 is adapted to receive the cleaned batteries and defective batteries flowing out of the unloading turntable 300, and the battery rejection device 600 is adapted to reject defective batteries based on the detection data of the first camera module 420 and the second camera module 510.

[0235] In this way, the battery rejection device 600 can accurately and reliably reject uncleaned batteries and unqualified cleaned batteries (both of which are defective batteries), thereby improving the reliability and stability of the cleaning equipment 100.

[0236] like Figure 1As shown, the feeding line 400 can be bent and extended, with one end for feeding and the other end equipped with a transition ratchet 410. The feeding turntable 200 is tangent to the transition ratchet 410, and the feeding turntable 200 is tangent to the first turntable 111, and is located at the loading and unloading position. A first camera module 420 can be installed above the feeding turntable 200, and a barcode scanner can be installed below it. Multiple clamping assemblies 120 are installed on the first turntable 111, and cleaning assemblies 130 are installed around the first turntable 111. There are multiple cleaning assemblies 130, and each... Cleaning components 130 are provided at each cleaning position. The unloading turntable 300 is tangent to the first turntable 111 and is located at the unloading position. The battery rejection device 600 is located downstream of the unloading turntable 300 and is used to receive the batteries transferred by the unloading turntable 300 and can reject defective batteries. A feeding line 500 is provided downstream of the battery rejection device 600. The feeding line 500 can be bent and is used to remove the cleaned batteries from the cleaning equipment 100, such as to the next process (sealing cap welding process).

[0237] Among them, the feeding turntable 200, the unloading turntable 300, and the transition plate 610 of the battery rejection device 600 are all meshed and driven with the first turntable 111. The first turntable 111 is poweredly connected to the cam divider 700 and can move and stop according to the drive angle of the cam divider 700.

[0238] The galvanometer module 131 and camera module 134 of the cleaning assembly 130 are mounted on the lead screw module 132. The lead screw module 132 is set on the marble base 133 to suppress vibration and improve accuracy. The camera module 134 and the galvanometer module 131 are optically coaxial for visual guidance.

[0239] Referring to the accompanying drawings, the cleaning process of the battery filling hole cleaning device 100 according to this application embodiment is as follows:

[0240] The first turntable 111 rotates under the drive of the cam divider 700, and the feeding turntable 200, the unloading turntable 300 and the transition plate 610 mesh with it and rotate synchronously.

[0241] The battery is carried by the positioning component 800, and the feeding line 400 feeds the battery. The transition ratchet 410 blocks and guides the battery to prevent jamming. After the battery enters the feeding turntable 200, the barcode scanner under the feeding turntable 200 identifies the electronic tag of the positioning component 800 and reads the battery information.

[0242] The battery is fed from the feeding turntable 200 to the first turntable. Before feeding, the first camera module 420 detects whether there are glue nails on the incoming battery. The clamp 124 on the clamp assembly 120 performs coarse positioning on the battery.

[0243] The first turntable 111 continues to rotate, the clamp 124 clamps the battery, and the release part 123 lifts the battery, and the battery cleaning component 130 cleans the battery at its location.

[0244] The first turntable 111 continues to rotate, completing the cleaning and unloading of the batteries to the unloading turntable 300, and then moving to the transition turntable 610;

[0245] The transition plate 610 continues to rotate. The battery packs that have been cleaned on the transition plate 610 are opposite to the rejection channel 630. Based on the battery information identified by the first camera module 420 and the second camera module 510, the driving component 622 corresponding to the defective battery is controlled to push the actuating plate 621. The actuating plate 621 drives the defective battery out of the receiving part 611. The battery that has been removed from the receiving part 611 can move along the battery channel 632 under the guidance and limiting action of the guide bar 631 on the rejection channel 630, opening the feeding door 641 to transfer the defective battery to the hopper 640.

[0246] The transition plate 610 continues to rotate, and after the battery is cleaned, it can be moved to the next process through the unloading line 500. The next process is the welding of the sealing cap of the injection hole.
