Description

Technical Field

[0001] This utility model belongs to the field of battery production technology, and in particular relates to a battery cleaning device. Background Technology

[0002] In the battery production process, a coating process is usually involved. During the coating process, defects such as wrinkles, bubbles and damage are prone to occur. The reason for these problems is mostly because the battery surface is uneven, which is usually caused by impurities on the surface.

[0003] Currently, batteries are typically cleaned of impurities on their surface using battery cleaning equipment before coating to reduce the occurrence of coating defects. However, in existing technology, most battery cleaning equipment can only clean large impurities on the battery surface and cannot remove fine aluminum powder or sand particles, resulting in a lower coating yield. Utility Model Content

[0004] The purpose of this invention is to provide a battery cleaning device to address the aforementioned technical problems.

[0005] In view of this, the present invention provides a battery cleaning device, comprising:

[0006] A feeding device for transporting batteries along a first direction;

[0007] The first cleaning device is installed on the battery transport path and is used to clean the bottom surface of the battery.

[0008] Two sets of second cleaning devices are respectively arranged on both sides of the feeding device along the second direction. The second cleaning devices include:

[0009] The static eliminator is used to remove static electricity from the large surface area of ​​the battery.

[0010] The cleaning mechanism is used to clean impurities adhering to the large surface of the battery;

[0011] The dust-wiping mechanism is used to wipe away impurities adhering to the large surface of the battery.

[0012] The static elimination mechanism, cleaning mechanism, and dust wiping mechanism are arranged sequentially along the battery transport path. The cleaning mechanism is also used to clean the surface of the dust wiping mechanism.

[0013] Furthermore, the cleaning mechanism includes a first brush roller, which is used to clean impurities attached to the large surface of the battery.

[0014] The dust removal mechanism includes a dust removal roller, which is used to wipe away impurities adhering to the large surface of the battery.

[0015] The first brush roller and the dust-wiping roller are arranged in parallel, and when the first brush roller and the dust-wiping roller rotate relative to each other, the first brush roller can clean the surface of the dust-wiping roller.

[0016] Furthermore, the second cleaning device also includes a first drive module for driving the first brush roller and the dust-wiping roller to rotate synchronously.

[0017] Furthermore, the second cleaning device also includes:

[0018] The vacuuming mechanism, mounted on the bracket, is used to remove impurities from the battery that have been processed by the second cleaning device.

[0019] Furthermore, the static eliminator includes a plasma blower module, which is used to blow static electricity away from the large surface of the battery.

[0020] Furthermore, the two plasma blowing modules are installed in a counter-firing configuration along the first direction.

[0021] Furthermore, the first cleaning device includes:

[0022] The second brush roller and the second brush are positioned on the battery transport path to clean the bottom surface of the battery.

[0023] The second drive module is located outside the feeding device and is used to drive the second brush roller to rotate.

[0024] Furthermore, it also includes an auxiliary pushing device, which includes:

[0025] Fixture;

[0026] A push rod is movably mounted on a fixed frame in a first direction and a third direction to assist in pushing the battery along the transport path;

[0027] The transfer module is mounted on a fixed frame and is used to control the movement of the push rod in a first direction and a third direction.

[0028] Furthermore, the transfer module includes:

[0029] Translation module, used to drive the push rod to move along the first direction;

[0030] The lifting module is used to drive the push rod to move in a third direction;

[0031] A buffer module is installed between the drive end of the lifting module and the push rod.

[0032] Furthermore, the feeding device includes:

[0033] A conveyor mechanism used to transport batteries;

[0034] A guiding mechanism is used to guide the moving battery along a first direction.

[0035] One of the above technical solutions has the following beneficial effects:

[0036] The feeding device transports the batteries. A first cleaning device is installed along the transport path to clean the bottom surface of the batteries on the feeding device. After passing through the first cleaning device, the batteries first pass through an anti-static mechanism to remove static electricity from their surface, preventing static electricity from affecting the subsequent cleaning effect. Then, they pass through a sweeping mechanism to remove impurities adhering to the large surface of the battery. Finally, the batteries pass through a dust wiping mechanism to remove carbon powder and dust that are difficult to clean from the large surface of the battery. This achieves effective cleaning of the large surface of the battery, avoiding abnormalities such as poor coating due to dust particles on the battery surface, and improving the coating yield.

[0037] The output end of the sweeping mechanism is in contact with the output end of the dust wiping mechanism. While the sweeping mechanism is cleaning the large surface of the battery, it is also cleaning the output end of the dust wiping mechanism to remove the dust adhering to the output end of the dust wiping mechanism, thus preventing the dust from accumulating on the output end of the dust wiping mechanism and affecting the dust wiping effect.

[0043] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0045] Example 1:

[0046] This embodiment provides a battery cleaning device, including:

[0047] Feeding device 1 is used to transport batteries along the first direction X;

[0048] The first cleaning device 2 is installed on the battery transport path and is used to clean the bottom surface of the battery.

[0049] Two sets of second cleaning devices 3 are respectively disposed on both sides of the feeding device 1 along the second direction Y. The second cleaning device 3 includes:

[0050] The static eliminator 31 is used to perform static elimination treatment on the large surface of the battery.

[0051] The cleaning mechanism 32 is used to clean impurities attached to the large surface of the battery.

[0052] The dust-wiping mechanism 33 is used to wipe away impurities adhering to the large surface of the battery;

[0053] Among them, the static elimination mechanism 31, the cleaning mechanism 32 and the dust wiping mechanism 33 are arranged sequentially along the transport path of the battery, and the cleaning mechanism 32 is also used to clean the surface of the dust wiping mechanism 33.

[0054] In this technical solution, the battery is transported and its surface is cleaned by battery cleaning equipment before the coating process, such as... Figure 1 As shown, the feeding device 1 can be a conveyor belt or a roller conveyor, etc. The feeding device 1 transports the battery along the first direction X. The first cleaning device 2 is set on the transport path to clean the bottom surface of the battery on the feeding device 1. After the battery passes the first cleaning device 2, it is transported by the feeding device 1 to the space between two second cleaning devices 3. Each second cleaning device 3 consists of a support 36, an antistatic mechanism 31, a sweeping mechanism 32, and a dust-wiping mechanism 33. The antistatic mechanism 31, the sweeping mechanism 32, and the dust-wiping mechanism 33 are all installed inside the support 36 and arranged sequentially along the battery transport path. The battery first passes through the antistatic mechanism 31, which performs antistatic treatment on the battery surface, removing aluminum powder, grit, and tiny plant fibers, which are then carried away and adhered to the battery surface. Next, the battery passes through the sweeping mechanism 32, which cleans and removes impurities adhering to the battery surface. Then, the battery passes through the dust-wiping mechanism 33, which wipes away carbon powder and dust that are difficult to remove from the battery surface. This achieves effective cleaning of the battery surface, avoiding subsequent coating defects caused by impurities on the battery surface and improving the coating yield.

[0055] In addition, the output end of the sweeping mechanism 32 is in contact with the output end of the dust wiping mechanism 33. While the sweeping mechanism 32 is sweeping the large surface of the battery, it will also sweep the output end of the dust wiping mechanism 33 to remove the dust adhering to the output end of the dust wiping mechanism 33, so as to avoid the dust from accumulating on the output end of the dust wiping mechanism 33 and affecting the dust wiping effect.

[0056] Example 2:

[0057] This embodiment provides a battery cleaning device, which, in addition to the technical solution of Embodiment 1 described above, also has the following technical features.

[0058] Furthermore, the cleaning mechanism 32 includes a first brush roller, which is used to clean impurities attached to the large surface of the battery.

[0059] The dust wiping mechanism 33 includes a dust wiping roller, which is used to wipe away impurities attached to the large surface of the battery.

[0060] The first brush roller and the dust-wiping roller are arranged in parallel, and when the first brush roller and the dust-wiping roller rotate relative to each other, the first brush roller can clean the surface of the dust-wiping roller.

[0061] In this technical solution, both the first brush roller and the dust-wiping roller are rotatably mounted on the bracket 36. The surface of the dust-wiping roller is made of polyurethane material, which can be the same material as the eraser for a 2B pencil, and it is in contact with the bristles of the first brush roller. By driving the first brush roller and the dust-wiping roller to rotate synchronously, the bristles of the first brush roller can sweep away impurities attached to the large surface of the battery, while the dust-wiping roller can wipe the large surface of the battery, causing carbon powder, dust, etc. on the large surface to adhere to the surface of the dust-wiping roller, thus achieving a dust-wiping effect. At the same time, because the bristles of the first brush roller are in contact with the surface of the dust-wiping roller, the first brush roller can also clean the surface of the dust-wiping roller, ensuring that the surface of the dust-wiping roller is clean and will not accumulate dust, affecting the next use.

[0062] Furthermore, the second cleaning device 3 also includes a first drive module 34 for driving the first brush roller and the dust-wiping roller to rotate synchronously. The first drive module 34 can consist of a drive motor 341 and a pulley assembly. The drive motor 341 is mounted on a bracket 36. The pulley assembly includes a driving pulley 342, two driven pulleys 343, and a transmission belt 344. The dust-wiping roller and the first brush roller are each connected to a driven pulley 343, and the output of the drive motor 341 is connected to the driving pulley 342. The drive motor 341 controls the rotation of the driving pulley 342, which then drives the two driven pulleys 343 to rotate via the transmission belt 344, thereby achieving synchronous rotation of the first brush roller and the dust-wiping roller. It is worth noting that the drive module 34 can also be other drive structures capable of driving the first brush roller and the dust-wiping roller to rotate synchronously in opposite directions; these will not be described in detail in this embodiment.

[0063] Example 3:

[0064] This embodiment provides a battery cleaning device, which, in addition to the technical solution of Embodiment 1 described above, also has the following technical features.

[0065] Furthermore, the second cleaning device 3 also includes:

[0066] The vacuuming mechanism 35 is mounted on the bracket 36 and is used to remove impurities from the battery that have been treated by the second cleaning device 3.

[0067] In this technical solution, the vacuuming mechanism 35 can be composed of a vacuuming pipe and a negative pressure module. The negative pressure module is installed outside the bracket 36 and communicates with the inside of the bracket 36 through the vacuuming pipe. Through this structural design, the impurities and dust cleaned by the second cleaning device 3 can be vacuumed up immediately, avoiding the impurities and dust from flying and causing pollution, which would affect the cleaning effect of the battery.

[0068] Example 4:

[0069] This embodiment provides a battery cleaning device, which, in addition to the technical solution of Embodiment 1 described above, also has the following technical features.

[0070] Furthermore, the static eliminator 31 includes a plasma blowing module, which is used to blow static electricity away from the large surface of the battery.

[0071] In this technical solution, the plasma blowing module can be an ion fan. The ion fan is used to remove static electricity from the large surface of the battery. Some aluminum powder, gravel and plant fiber particles will be carried away and adhered to the large surface by the ion fan.

[0072] Furthermore, the two plasma blowing modules are installed in a facing-to-facing manner along the first direction X. This structural design allows the airflow direction of the two plasma blowing modules to be adjusted to achieve a circulating return air effect, thereby effectively reducing energy waste, lowering operating costs, and achieving energy conservation and consumption reduction.

[0073] Example 5:

[0074] This embodiment provides a battery cleaning device, which, in addition to the technical solution of Embodiment 1 described above, also has the following technical features.

[0075] Furthermore, the first cleaning device 2 includes:

[0076] The second brush roller and the second brush are positioned on the battery transport path to clean the bottom surface of the battery.

[0077] The second drive module is located outside the feeding device 1 and is used to drive the second brush roller to rotate.

[0078] The second drive module can be a motor directly connected to the second brush roller, or other mechanisms that can drive the second brush roller to rotate, which will not be elaborated here.

[0079] In this technical solution, the second brush roller is rotatably mounted on the feeding device 1, and the bristles of the second brush roller can contact the bottom surface of the battery on the transport path. When the battery is transported by the feeding device 1 through the second brush roller, the bristles of the second brush roller clean the bottom surface of the battery, thereby cleaning the bottom surface of the battery.

[0080] Example 6:

[0081] This embodiment provides a battery cleaning device, which, in addition to the technical solution of Embodiment 1 described above, also has the following technical features.

[0082] Furthermore, it also includes an auxiliary pushing device 4, which includes:

[0083] Fixture 41;

[0084] A push rod 42 is movably mounted on a fixed frame 41 in a first direction X and a third direction Z, and is used to assist in pushing the battery to move along the transport path.

[0085] The transfer module is mounted on the fixed frame 41 and is used to control the push rod 42 to move along the first direction X and the third direction Z.

[0086] In this technical solution, during the battery transportation process, the feeding device 1 may stop on the feeding device 1 due to the excessive weight of the battery. By setting an auxiliary pushing device 4, the transfer module installed on the fixed frame 41 drives the pushing rod 42 to move along the first direction X and the third direction Z. The pushing rod 42 can push the battery to a suitable position, ensuring that the feeding device 1 can normally transport the battery along the first direction X, and preventing the battery from stopping and affecting subsequent cleaning operations.

[0087] Example 7:

[0088] This embodiment provides a battery cleaning device, which, in addition to the technical solution of embodiment 6 above, also has the following technical features.

[0089] Furthermore, the transfer module includes:

[0090] Translation module 43 is used to drive push rod 42 to move along the first direction X;

[0091] Lifting module 44 is used to drive push rod 42 to move along the third direction Z;

[0092] A buffer module 45 is provided between the drive end of the lifting module 44 and the push rod 42.

[0093] In this technical solution, the lifting module 44 can be installed on the output end of the translation module 43. The translation module 43 can be a sliding electric cylinder or a sliding pneumatic cylinder, which can drive the lifting module 44 to move linearly in the first direction X. Preferably, a sliding electric cylinder is used, which can drive the lifting module 44 to move stably and accurately along the first direction X.

[0094] The lifting module 44 can be composed of a fixed base 441, a movable base 442 and a driving component 443. The fixed base 441 is installed on the output end of the transfer module. The movable base 442 is movable on the fixed base 441 in the third direction Z. The driving component 443 can be a driving cylinder. The driving cylinder is installed on the fixed base 441 and its output end is connected to the movable base 442. It is used to control the movable base 442 to move in the third direction Z. The push rod 42 is fixedly installed on the movable base 442, thereby realizing the movement of the push rod 42 in the third direction Z.

[0095] In addition, a buffer module 45 is provided at the connection between the movable seat 442 and the drive cylinder. When the push rod 42 accidentally touches the top of the battery while moving along the third direction Z, the buffer module 45 plays a buffering role to prevent the push rod 42 from pressing down on the top of the battery and causing an indentation on the top cover.

[0096] Furthermore, the buffer module 45 consists of a slide rod 451 and an elastic element 452. One end of the slide rod 451 is connected to the output end of the drive cylinder, and the other end passes through the movable seat 442. The elastic element 452 can be a spring sleeve mounted on the slide rod 451, with both ends axially abutting against the ends of the slide rod 451 and the movable seat 442, respectively. A detachable abutment block 453 is provided on the end of the slide rod 451 near the movable seat 442. The abutment block 453 is used to abut against the movable seat 442 and to facilitate the installation of the elastic element 452.

[0097] When the buffer module 45 is working, the drive cylinder controls the slide rod 451 to move, causing the elastic element 452 to abut against the movable seat 442, pushing the movable seat 442 to move, thereby driving the push rod 42 on the movable seat 442 to move. When the push rod 42 abuts against the top cover of the battery, the movable seat 442 will move upward along the third direction Z to squeeze the elastic element 452, causing the spring to be compressed, thereby playing a buffering role and preventing the top cover of the battery from being crushed by the push rod 42.

[0098] Example 8:

[0099] This embodiment provides a battery cleaning device, which, in addition to the technical solution of embodiment 6 above, also has the following technical features.

[0100] Furthermore, the feeding device 1 includes:

[0101] The conveying mechanism 11 is used to transport the battery and can be a roller conveyor; the guiding mechanism 12 is used to guide the moving battery along the first direction X. The guiding mechanism 12 can be a number of guide wheels, which are installed on both sides of the roller conveyor in the second direction Y. When the roller conveyor drives the battery to move, the guide wheels roll into contact with the two large surfaces of the battery, guiding the battery to move along the first direction X.

[0102] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
