The battery monomer can be at notes liquid mouthful remaining electrolyte around the back after annotating the liquid, through high temperature stewing and formation process, annotate the electrolyte of liquid mouth and can produce the difficult washing of crystallization, and this crystallization can lead to when sealing weld, produces the detonation and leads to the battery weeping, consequently need wash annotating the liquid mouth before sealing weld.

The inventor notices that the current method for removing the residual electrolyte near the single battery filling opening is mainly manual cleaning, and the treatment method has the problems of low cleaning efficiency and poor cleaning effect particularly on the electrolyte crystal in the bottom groove of the sealing nail at the filling opening.

In order to solve the problem that battery monomer annotates liquid mouth cleaning efficiency low and cleaning performance is poor, the applicant research discovery can replace artifical the execution to annotating the washing operation of liquid mouth through the cleaning head rotation, can increase the dynamics of cleaing away to annotating the crystal electrolyte liquid of liquid mouth bottom and guarantee the cleaning performance. Specifically, in order to prevent the electrolyte from remaining around the injection port from crystallizing, repeated scrubbing work around the injection port by a simulation worker is performed, and the cleaning head is driven to reciprocate relative to the injection port of the battery cell while driving the cleaning head.

Based on the above consideration, in order to solve the problems of low cleaning efficiency and poor cleaning effect when residual electrolyte in the electrolyte injection port is manually cleaned, the inventor has conducted extensive research and has designed a cleaning device, wherein the cleaning device is provided with a cleaning mechanism and a driving mechanism, and the driving mechanism drives respective cleaning portions of the cleaning mechanism to reciprocate relative to respective corresponding electrolyte injection ports of cleaned battery cells so as to perform cleaning operation on the current electrolyte injection ports of the battery cells, so that the cleaning device is high in cleaning efficiency and good in cleaning effect. Meanwhile, the cleaning parts can reciprocate relative to the liquid injection port of the battery monomer cleaned by the cleaning parts, so that the liquid injection port of the battery monomer and the periphery of the liquid injection port can be scrubbed in a reciprocating manner, the cleaning range is wide, and the cleaning effect is enhanced.

The cleaning device related to the embodiment of the application can be but is not limited to cleaning the liquid injection port of the single battery, wherein the single battery can be a cylindrical single battery or a square single battery. In addition, the cleaning equipment can also clean other parts of the battery cells, such as end covers, and can also clean other components (such as the whole of the battery module and the battery pack and parts thereof) which need to be cleaned besides the battery cells. The equipment for cleaning the component to be cleaned only by adopting the technical scheme of the cleaning equipment related to the embodiment of the application belongs to the protection scope of the application, and the type of the component to be cleaned is not limited specifically.

The electric toy may include a stationary or mobile electric toy, such as a game machine, an electric car toy, an electric ship toy, an electric airplane toy, and the like, and the spacecraft may include an airplane, a rocket, a space shuttle, a spacecraft, and the like.

The battery cell can be in a cylinder, a flat body, a cuboid or other shapes. The battery cell generally includes a case, an electrode assembly, a terminal, a current collecting member, and the like. The electrode assembly is disposed inside the case and is electrically connected with the pole through the current collecting member.

Electrolyte is injected into the shell and enters between the pole pieces of the electrode assembly to perform electrochemical reaction with active substances on the pole pieces, so that a charging and discharging process is generated.

According to some embodiments of the present application, referring to fig. 1 and 2, the present application provides a cleaning apparatus 10 for cleaning a liquid injection port of a battery cell 20, including a cleaning mechanism 100 and a driving mechanism 200. The cleaning mechanism 100 includes at least one cleaning part 110, and each cleaning part 110 is configured to be rotatable about its central axis. The driving mechanism 200 drives each cleaning unit 110 to reciprocate with respect to the liquid injection port of the corresponding cleaned battery cell 20 while the cleaning unit 110 rotates, so as to perform the cleaning operation on the liquid injection port of the current battery cell 20.

In the use state, the cleaning unit 110 is provided toward the liquid inlet of the battery cell 20, and when the cleaning unit 110 rotates around its center axis, the cleaning unit can rotate and clean the liquid inlet of each corresponding battery cell 20. The cleaning part 110 may be, but is not limited to, a cleaning brush.

The driving mechanism 200 is drivingly connected to each cleaning unit 110, and drives each cleaning unit 110 to reciprocate with respect to the liquid inlet of the battery cell 20 cleaned by itself while each cleaning unit 110 rotates. The reciprocating direction corresponding to each cleaning portion 110 may be the same or different, and the reciprocating direction corresponding to the reciprocating motion may be a linear direction, a curved direction, or an arc direction. For example, the cleaning part 110 reciprocates in a linear direction in a vertical plane with respect to its central axis, or the cleaning part 110 reciprocates up and down along its central axis, or the cleaning part 110 reciprocates in a circumferential direction around its central axis, or the like. The direction in which each cleaning portion 110 reciprocates is not limited, and it is sufficient if the liquid inlet of the battery cell 20 can be cleaned in a reciprocating manner.

Preferably, the driving mechanism 200 can drive all the cleaning parts 110 to reciprocate synchronously along the preset direction, and the driving manner is simple, which helps to reduce the cost. Specifically, when the predetermined direction is a linear direction, the driving mechanism 200 may be a linear motor, a telescopic cylinder, or the like, which can generate a linear driving force to drive the entire cleaning part 110 to linearly reciprocate. When the predetermined direction is an arc direction, the driving mechanism 200 may be a driving member capable of generating a torque force, such as a rotary rocker arm, to drive the entire cleaning part 110 to move in an arc reciprocating manner. Of course, the driving mechanism 200 may control each cleaning unit 110 to reciprocate independently in each reciprocating direction, and is not limited herein.

The same cleaning part 110 can correspondingly clean at least one battery cell 20, and when the cleaning part 110 reciprocates, the liquid injection port of at least one battery cell 20 to be cleaned can be repeatedly scrubbed. When the cleaning part 110 is large in size, it can cover two or more adjacent battery cells 20, so that the same cleaning part 110 can repeatedly scrub the liquid injection ports of two or more adjacent battery cells 20.

The cleaning device 10 cleans the liquid injection port of the battery cell 20 by the rotation of the cleaning part 110, and has high cleaning efficiency and good cleaning effect. Meanwhile, the driving mechanism 200 drives the respective cleaning parts 110 to reciprocate relative to the liquid injection port of the battery cell 20 cleaned by itself, so that the liquid injection port of the battery cell 20 and the periphery thereof can be scrubbed back and forth, and the cleaning effect is enhanced and the cleaning range is wide.

Referring to fig. 1, in some embodiments, the reciprocating motion of each cleaning portion 110 with respect to the liquid injection port of each corresponding battery cell 20 to be cleaned is a linear reciprocating motion in a plane perpendicular to the central axis of each cleaning portion.

The central axes of the respective cleaning portions 110 may be parallel or may intersect. When the central axes of the cleaning parts 110 are arranged in parallel, the cleaning parts 110 can reciprocate linearly in the same plane. When the central axes of the cleaning parts 110 intersect with each other, at least two cleaning parts 110 linearly reciprocate in different planes, respectively.

In order to achieve the linear reciprocating motion of each cleaning part 110, the driving mechanism 200 may include a driving member such as a linear motor, a telescopic cylinder, etc. to drive each cleaning part 110 to linearly reciprocate, and the specific configuration of the driving mechanism 200 is not limited herein.

In this case, the driving mechanism 200 can drive the respective cleaning units 110 to reciprocate more easily, which contributes to a reduction in facility cost.

In practical applications, it is preferable that the central axes of the cleaning parts 110 are parallel to each other, and in this case, the battery cells 20 can be placed on the same plane, so that the overall structure of the cleaning apparatus is simpler, and the driving manner of the driving mechanism 200 is also simpler. It is further preferable that the driving mechanism 200 drives all the cleaning parts 110 to reciprocate linearly in a plane perpendicular to the central axes of all the cleaning parts 110, and this is easy and contributes to cost reduction. Specifically, all the cleaning parts 110 may be arranged at intervals along a plane perpendicular to the central axis of all the cleaning parts 110, and all the cleaning parts 110 clean the liquid injection ports of one single battery 20 in a one-to-one correspondence manner, so that the single battery 20 can be conveniently loaded and unloaded along the arrangement direction of the cleaning parts 110.

Referring to fig. 1, in some embodiments, the cleaning apparatus 10 includes a worktable 500 having a working surface a with a first cleaning region a1 for placing the battery cells 20, the cleaning apparatus 10 further includes a first moving mechanism 300 and a cleaning member 600, and the cleaning mechanism 100 is connected with the driving mechanism 200 and is commonly mounted on the first moving mechanism 300. The decontaminating member 600 is disposed at one side of the first cleaning area a1 and performs active or passive cleaning of the cleaning mechanism 100, and the first moving mechanism 300 is used for driving the cleaning mechanism 100 to move between the first cleaning area a1 and the decontaminating member 600.

The worktable 500 is a supporting structure for placing the battery cells 20, and may be a structure such as a supporting plate, a supporting frame, a supporting column, and the like, which is not limited herein. The cleaning mechanism and the driving mechanism 200 may be disposed on the table 500, or may not be disposed on the table 500, which is not limited herein. The working surface a may be, but is not limited to, a plane, and the plane is convenient for carrying the battery cell 20. In the use state, the working surface a may be parallel to the horizontal plane.

When the cleaning mechanism 100 moves to the decontaminating member 600, the decontaminating member 600 actively or passively cleans the cleaning portion 110 of the cleaning mechanism 100. The active cleaning mechanism 100 for the decontaminating member 600 means that the decontaminating member 600 has power and cleaning liquid for cleaning the cleaning part 110, and for example, the decontaminating member 600 includes a high pressure water gun which can flush dirt (electrolyte crystals, etc.) on the cleaning part 110 when high pressure water is sprayed to the cleaning part 110 of the cleaning mechanism. The decontaminating member 600 passively cleans the cleaning mechanism 100 means that the decontaminating member only provides a cleaning solution for cleaning the cleaning mechanism 100, for example, the decontaminating member 600 includes a cleaning tank for holding the cleaning solution. The specific form of the decontaminating member 600 is not limited as long as the cleaning mechanism 100 can perform cleaning at the decontaminating member 600.

First movement mechanism 300 drives wash mechanism 100 and drive mechanism 200 to move together between the first cleaning zone and soil removal member 600. The specific moving manner is not limited, and may be translation, curvilinear movement, and the like, and similarly, the specific structural form of the first moving mechanism 300 is various, and the structures of different moving manners are different, which is not described and defined herein, and those skilled in the art can reasonably set the moving manner according to actual needs.

At this time, after the cleaning mechanism 100 performs the cleaning operation on the liquid injection port of the battery cell 20, the cleaning mechanism is driven by the first moving mechanism 300 to move to the cleaning member 600 to perform the cleaning operation, so as to clean the liquid injection port of the battery cell 20 next time, thereby improving the cleaning effect on the liquid injection port of the battery cell 20 and avoiding cross contamination of the battery cell 20.

Preferably, the first moving mechanism 300 drives the cleaning mechanism 100 and the driving mechanism 200 to move together along the third linear direction (in this case, the first moving mechanism 300 may be a linear motor, a telescopic cylinder, or the like), and in this case, the device structure and the driving manner are simple. Specifically, the third linear direction is perpendicular to the direction of the linear reciprocating motion performed by all the cleaning units 110 in synchronization, so that the cleaning member 600 is not located on the moving path of the cleaning units 110 driven by the driving mechanism 200, contributing to shortening the size of the cleaning apparatus in a certain direction.

In other embodiments, the workbench 500 may be a separate component from the washing apparatus 10, that is, the washing apparatus 10 may not be provided with the workbench 500, and when the washing apparatus 10 is applied to an apparatus having the workbench 500, the washing operation of the washing apparatus 10 on the battery cells 20 provided on the working surface a of the workbench 500 may also be performed.

Referring to fig. 1, in some embodiments, the working surface a has a second cleaning area a2 for placing the battery cell 20, the cleaning element 600 is disposed between the first cleaning area a1 and the second cleaning area a2, and the first moving mechanism 300 is configured to drive the cleaning mechanism 100 to move between the first cleaning area a1, the cleaning element 600 and the second cleaning area a 2.

When the cleaning device 10 is operated, the cleaning mechanism 100 reaches the cleaning member 600 to clean the cleaning portion 110 after cleaning the liquid injection port of the battery cell 20 on the first cleaning area a1, then reaches the first cleaning area a1 to clean the liquid injection port of the battery cell 20 thereon, and then returns to the cleaning member 600 to clean the cleaning portion 110, and so on.

When the cleaning mechanism 100 cleans the liquid injection port of the battery cell 20 on one of the cleaning areas, the second cleaning area a2 can be conveniently loaded, so that the continuous cleaning operation of the cleaning mechanism 100 can be realized, and the working efficiency of the cleaning mechanism 100 is improved.

Certainly, in practical application, the cleaning mechanism 100 may also perform the cleaning operation only for the liquid injection port of the single battery 20 in the first cleaning region a1 or the second cleaning region a2, and at this time, the arrangement of the two cleaning regions facilitates the failure of the corresponding loading and unloading device in one of the cleaning regions, and the cleaning device 10 does not need to be shut down, and the loading and unloading device in the other cleaning region still can be used for loading and unloading the single battery 20, so that the failure influence is reduced, and the reliability of the device operation is improved.

Of course, in other embodiments, the working surface a may include a greater number of cleaning regions, and accordingly the number of cleaning mechanisms 100 may be increased, which is not specifically limited and described herein.

Preferably, the first cleaning region a1 and the second cleaning region a2 are spaced apart in a direction perpendicular to a direction in which all the cleaning parts 110 reciprocate linearly in synchronization, and at this time, when loading and unloading of the battery cells 20 are performed in the direction of the linear reciprocating motion, loading and unloading of the battery cells 20 may be independently performed in the first cleaning region a1 and the second cleaning region a 2.

Referring to fig. 1 and 3, the first moving mechanism 300 may alternatively include two spaced-apart gantries 310 supported on the working surface a, a linear module 320 disposed on one of the gantries 310, and a linear guide 330 disposed on the other gantry 310, and the cleaning mechanism 100, the driving mechanism 200, and the cleaning member 600 are disposed between the two gantries 310. Specifically, the driving mechanism 200 is connected to the linear module and the linear guide 330, and drives the cleaning mechanism 100 to switch among the first cleaning area a1, the decontaminating member 600 and the second cleaning area a2 when moving along the linear guide 330 under the driving of the linear module 320.

Referring to fig. 4 and 5, in some embodiments, the cleaning element 600 includes a cleaning tank for holding a cleaning solution, and all of the cleaning portions 110 of the cleaning mechanism 100 can extend into the cleaning tank to perform a self-cleaning operation.

When the cleaning mechanism 100 reaches the cleaning member 600, it can be inserted into the cleaning tank to perform a self-cleaning operation. When the cleaning mechanism 100 performs the self-cleaning operation, all the cleaning parts 110 rotate along their own central axes, and the dirt carried by the cleaning parts 110 is dissolved in the cleaning liquid during the rotation.

When the cleaning mechanism 100 reaches the cleaning member 600, the cleaning tank may be raised to a predetermined position or the cleaning mechanism 100 may be lowered to the predetermined position in order to allow the cleaning mechanism 100 to extend into the cleaning tank. Specifically, the cleaning tank may be mounted on a first lifting mechanism, or the cleaning mechanism 100 may be mounted on a second lifting mechanism, and the second lifting mechanism may be mounted on the first moving mechanism 300 via the driving mechanism 200 (or the cleaning mechanism 100 may be mounted on the second lifting mechanism via the driving mechanism 200, and the second lifting mechanism may be directly mounted on the first moving mechanism 300). The first and second lifting mechanisms may be, but are not limited to, lifting cylinders.

Of course, in other embodiments, after the cleaning part 110 extends into the cleaning tank, the cleaning part 110 may be manually cleaned.

The total cleaning portions 110 are parallel to each other means that the central axes of the total cleaning portions 110 are parallel to each other. The second moving mechanism 400 drives the mounting plate 120 to move in a direction parallel to the central axis of the entire cleaning part 110. When the driving mechanism 200 drives the mounting plate 120 to reciprocate, all the cleaning parts 110 synchronously reciprocate in the same direction.

In the use state, the central axis of the cleaning part 110 is arranged along the vertical direction, and the second moving mechanism 400 drives the mounting plate 120 to move along the vertical direction at this time, that is, the lifting of the whole cleaning part 110 is realized.

When the cleaning mechanism 100 reaches above the battery cell 20 located in the first cleaning region a1, the second moving mechanism 400 drives the mounting plate 120 to descend to the cleaning portion 110 to reach the liquid injection port of the battery cell 20. After the cleaning is finished, the second moving mechanism 400 drives the mounting plate 120 to ascend to the cleaning portion 110 and leave from the liquid injection port of the battery cell 20, and the cleaned battery cell 20 can be discharged, so that the battery cell 20 to be cleaned can be charged again.

At this time, the second moving mechanism 400 can accurately clean the cleaning portion 110 to the injection port, and at the same time, facilitate loading and unloading of the battery cell 20.

Of course, the above effect can be achieved by lifting the working platform 500 in other embodiments.

In an embodiment, referring to fig. 2, the second moving mechanism 400 includes a second rail 410 and a power part 420, the second rail 410 extends in a direction parallel to the central axis of the cleaning part 110, the mounting plate 120 is slidably disposed on the second rail 410, and the power part 420 is drivingly connected to the mounting plate 120 and controls the movement along the rails.

Specifically, with continued reference to fig. 2, the second moving mechanism 400 further includes a connecting plate 430, the second rail 410 and the power unit 420 are both mounted on the connecting plate 430, and the connecting plate 430 is connected to the driving mechanism 200 and is driven by the driving mechanism 200 to move, so as to realize the reciprocating motion of the cleaning unit.

Referring to fig. 1 and 10, in some embodiments, the cleaning apparatus 10 includes a work table 500 and a conveying device 700, the work table 500 has a work surface a for placing the battery cells 20, and the conveying device 700 is disposed on the work table 500 and is used for loading and unloading the battery cells 20 on the work surface a.

The conveying device 700 may be, but is not limited to, a robot, a conveying rail 710, a belt, etc., and the conveying device 700 loads and unloads the battery cells 20 onto the working surface a includes conveying the battery cells 20 to be cleaned to the working surface a and removing the cleaned battery cells 20 from the working surface a.

At this time, the conveying device 700 is arranged to realize automatic loading and unloading of the single batteries 20, and the automation degree of the equipment is improved.

The battery cell 20 is placed on the conveying rail 710, and is located on the working surface a when reaching the first rail section under the conveying of the conveying rail 710. When the cleaning mechanism 100 performs a cleaning operation on the single batteries 20 on the working surface a, the single batteries 20 are still in the conveying rails 710, and the single batteries 20 can be limited by the conveying rails 710. Specifically, the conveying rail 710 is configured to form a conveying groove in which the battery cell 20 or the pallet carrying the battery cell 20 is retained. The conveying rail 710 may perform the conveyance of the battery cells 20 based on a conveyor belt, a conveying roller, or the like.

When the battery cell 20 is conveyed to the set position on the working surface a, the battery cell 20 is stopped by the protruding blocking member 800 and cannot be conveyed forward, which indicates that the battery cell 20 is conveyed to the position, and the conveying rail 710 may or may not stop running. After the battery cells 20 are cleaned, the blocking member 800 is switched to the retracted state, and the battery cells 20 leave the working surface a under the conveying of the conveying rail 710, so that the blanking of the battery cells 20 is realized.

The barrier 800 may be, but is not limited to, a telescopic cylinder. The barrier 800 may also include a sensor (e.g., a correlation sensor, a proximity switch, an infrared sensor, etc.) that senses the battery cell 20 when the sensor senses that the barrier 800 has been switched to the extended state. The cleaning device 10 further comprises a controller, the blocking member 800 is in communication connection with the controller, and the controller is configured to control the blocking member 800 to switch to the retraction state and keep for a certain time after the cleaning of the battery cells 20 is completed, so that the plurality of cleaned battery cells 20 can be discharged smoothly even when being sensed by the sensor.

At this time, the conveying rails 710 are directly disposed on the working surface a, so that the process of transferring the single battery cells 20 from the conveying device 700 to the working surface a can be omitted, and the loading and unloading of the single battery cells 20 are faster. Meanwhile, the blocking member 800 is used for limiting the battery cell 20 to be conveyed in place, so that not only can the accurate positioning of the battery cell 20 on the working surface a be realized, but also the conveying rail 710 can be allowed to be kept in a running state all the time, and the running control of the conveying rail 710 is simpler.

Understandably, when the working surface a has a plurality of cleaning areas, the conveying device 700 includes a plurality of first rail sections, and the plurality of first rail sections are disposed in the plurality of cleaning areas in a one-to-one correspondence manner.

In actual operation, the plurality of battery cells 20 may be sequentially conveyed between all the first clamping blocks 910 and all the second clamping blocks 920 by the conveying rail 710 along the feeding and discharging direction, and when the battery cell 20 at the most upstream is blocked by the blocking member 800, the battery cell 20 is in place, and at this time, all the first clamping blocks 910 and all the second clamping blocks 920 are synchronously close to each other to clamp each battery cell 20 under the driving of the first clamping cylinder 930 and the second clamping cylinder 940, respectively.

Of course, when the feeding and discharging direction of the battery cells 20 is not the above-mentioned "moving direction in which the entire cleaning part 110 is synchronously linearly reciprocated along the plane perpendicular to the central axis of the entire cleaning part 110 by the driving mechanism 200", all the first clamping blocks 910 and all the second clamping blocks 920 may also be arranged and moved in the above-mentioned manner. Alternatively, in other embodiments, the clamping driving portion drives each pair of the first clamping block 910 and the second clamping block 920 which are disposed opposite to each other to approach or separate from each other independently, which is not limited herein.
