Technical Field

[0001] This application relates to the technical field of batteries, and particularly to a dust removal device and battery production equipment. Background Art

[0002] Welding is an important link in the battery production process, and substances such as welding slag will be generated during welding. The existence of welding slag will affect the use effect or service life of the battery. Therefore, the cleaning of welding slag after welding is a technical problem that needs to be solved urgently. Summary of the Utility Model

[0003] Based on this, this application provides a dust removal device and battery production equipment to improve the cleaning effect of welding slag, thereby improving the use effect and service life of the battery.

[0004] In a first aspect, this application provides a dust removal device, including: a base; a dust removal component, including a dust suction hood and a cleaning member, the dust suction hood is arranged on the base, the cleaning member is movably arranged in the dust suction hood, and the cleaning member is configured to clean the welding slag on the battery monomer prefabricated part; a first driving mechanism arranged on the base, the first driving mechanism is connected to the cleaning member, and the first driving mechanism is configured to be able to drive the cleaning member to move along a first direction; and a second driving mechanism connected to the base, the second driving mechanism is configured to be able to drive the base to move along the first direction.

[0005] In the technical solution of the embodiment of this application, by setting the first driving mechanism to drive the cleaning member in the dust removal component to move along the first direction, and by setting the second driving mechanism to drive the entire dust removal component to move along the first direction. In this way, the positions of the dust suction hood and the cleaning member in the first direction can be adjusted more flexibly, so that the positions of the dust suction hood and the cleaning member relative to the part to be cleaned in the first direction can be adjusted according to the surface of the part to be cleaned, so that the cleaning member is convenient for cleaning the welding slag while the dust suction hood is convenient for sucking the welding slag, so that the cleaning effect of the welding slag can be improved, and thus the use effect and service life of the battery can be improved. In addition, since the second driving mechanism can quickly move the overall component to a rough position, and the first driving mechanism can adjust the position of the cleaning member, the efficiency of removing welding slag can be improved.

[0006] In some embodiments, the dust removal device further includes a third driving mechanism; the third driving mechanism is connected between the first driving mechanism and the cleaning member, and the third driving mechanism is configured to be able to drive the cleaning member to rotate around a first axis; the extending direction of the first axis is parallel to the first direction.

[0007] By providing the third driving mechanism, the cleaning member can be rotated, so that after the cleaning member reaches the desired position, the cleaning member can be rotated, so that the welding slag can be cleaned. Since the rotating cleaning member can continuously contact the welding slag, the welding slag can be cleaned more quickly through the centrifugal force and friction force generated by the cleaning member.

[0008] In some embodiments, the third driving mechanism includes: a driving member, which is arranged on a base; a first rotating member, which is connected to the driving member; the driving member is configured to drive the first rotating member to rotate around a second axis, and the second axis and the first axis are parallel to each other; and a second rotating member, which is suitable for meshing and connecting with the first rotating member, and the second rotating member can rotate around the first axis in response to the rotation of the first rotating member; wherein the second rotating member has a first side and a second side arranged opposite to each other along a first direction, the first side of the second rotating member is rotatably connected to the first driving mechanism, and the second side of the second rotating member is connected to the cleaning member.

[0009] By configuring the third driving mechanism to include a driving member, a first rotating member and a second rotating member, and the first rotating member and the second rotating member can be meshed and connected, the rotational motion output by the driving member is output to the cleaning member via the first rotating member and the second rotating member. Since the first rotating member and the second rotating member are transmitted by meshing connection, the cleaning member can rotate more continuously and stably during the cleaning process, and power fluctuation can be reduced, thereby improving the cleaning quality. Since the first driving mechanism and the second rotating member are rotatably connected, when the first driving mechanism outputs linear motion, the teeth meshed with the first rotating member and the second rotating member can be used to guide the movement of the second rotating member along the first direction, so that the cleaning member can move more accurately along the first direction under the drive of the second rotating member, which is conducive to controlling the position of the cleaning member, and then is conducive to cleaning welding slag at different positions. At the same time, by arranging the first rotating member and the second rotating member, not only can the driving member be installed in a more suitable position, but also can cooperate with the first driving mechanism to achieve the coexistence of these two motion modes of linear motion and rotational motion, thereby improving the compactness and space utilization of the device as a whole.

[0010] In some embodiments, the first rotating member includes a first rotating part and a plurality of first teeth, the first rotating part is connected to the driving member, and the plurality of first teeth are arranged on the outer peripheral surface of the first rotating part around the second axis; the second rotating member includes a second rotating part and a plurality of second teeth, the plurality of second teeth are arranged on the outer peripheral surface of the second rotating part around the first axis, and the second teeth are suitable for meshing with the first teeth; wherein, along the first direction, the size of the first tooth is larger than the size of the second tooth; or, along the first direction, the size of the first tooth is smaller than the size of the second tooth.

[0011] By controlling the dimensions of the first tooth portion and the second tooth portion in the first direction, the entire thickness range of the corresponding tooth portions can be utilized to achieve the movement of the cleaning member, thereby effectively increasing the effective stroke of the cleaning member moving in the first direction. In this way, there is no need to additionally occupy a large amount of space to set up a complex guiding structure, and the movement of the cleaning member in the first direction is achieved within a relatively compact space, further improving the space utilization rate.

[0012] In some embodiments, the cleaning member includes a seat body and at least one brush unit; the seat body has a first surface and a second surface oppositely arranged in the first direction, the first surface is connected to the first driving mechanism, the second surface is provided with the brush unit, and a gap space is defined between the second surface and the brush unit.

[0013] By defining a gap space between the second surface and the brush unit, not only can a deformation space be provided for the brush unit, which is beneficial to cleaning the welding slag, but also more diffusion space is provided for the welding slag and other impurities to be cleaned, and more disturbances can be generated when the airflow passes through the gap space, which is further beneficial to the detachment of the welding slag and other impurities from the brush unit and is beneficial to the dust removal operation by means of the dust suction hood, thereby improving the welding slag cleaning effect and the dust removal effect.

[0014] In some embodiments, a plurality of brush units are provided, the brush units are longitudinally extended and arranged on the second surface, and the brush units have a first end and a second end oppositely arranged along the longitudinal direction of the brush unit; the first ends of all the brush units are connected, and the second ends of all the brush units are arranged at intervals around the central axis of the seat body; the extending direction of the central axis of the seat body and the first direction are parallel to each other.

[0015] In this way, not only is it beneficial to make all the brush units form a region with a larger coverage range, which is convenient for cleaning the welding slag, but also the space occupied by the brush units can be reduced as much as possible, thereby being beneficial to improving the dust removal effect.

[0016] In some embodiments, a junction portion is defined at the connection of the first ends of all the brush units, and the center of the junction portion is located on the central axis of the seat body.

[0017] In this way, the force can be more effectively transmitted and distributed to each brush unit, the forces received by each brush unit are relatively balanced, the overall mechanical properties and reliability of the brush are improved, and thus the cleaning effect is improved.

[0018] In some embodiments, a junction portion is defined at the connection of the first ends of all the brush units, and all the brush units are symmetrically arranged about the center of the junction portion.

[0019] In this way, not only is it beneficial to enhance the structural stability, but also it is beneficial to improve the consistency of the cleaning effect.

[0020] In some embodiments, four brush units are provided.

[0021] In this way, while minimizing the space occupied by the brush units as much as possible, the cleaning effect of the cleaning member and the dust removal effect of the dust suction member can be improved.

[0022] In some embodiments, the longitudinal direction of the brush unit is a straight line direction; alternatively, the longitudinal direction of the brush unit is a curved direction.

[0023] When the longitudinal direction of the brush unit is a straight line direction, it is not only beneficial for manufacturing but also conducive to more evenly transmitting force to various parts, improving the stability of the cleaning force and the cleaning effect. When the longitudinal direction of the brush unit is a curved direction, it can not only better conform to the surfaces of various complex shapes but also, when the brush unit encounters obstacles or uneven surfaces, buffer the impact force through its own bending structure, reducing damage to the brush unit and the object to be cleaned. The longitudinal direction of the brush unit can be flexibly set and is not specifically limited herein.

[0024] In some embodiments, the dust suction hood has a circumferential side wall disposed around the central axis of the cleaning member, and a dust suction port is provided on the circumferential side wall of the dust suction hood; the extending direction of the central axis of the cleaning member and the first direction are parallel to each other.

[0025] Since the circumferential side wall of the dust suction hood is disposed around the central axis of the cleaning member, the dust suction ports are distributed around the cleaning member, which is conducive to sucking impurities such as welding slag, thereby improving the dust suction efficiency. At the same time, when the cleaning member is working, it will drive the surrounding air to flow to form an air flow, which enables the dust suction ports to suck impurities such as welding slag along the trend, thereby improving the dust suction effect.

[0026] In some embodiments, a plurality of dust suction ports are provided, and all the dust suction ports are symmetrically arranged on the circumferential side wall of the dust suction hood with respect to the central axis of the cleaning member.

[0027] Since the dust suction ports are symmetrically arranged, a more stable dust suction area can be formed around the cleaning member, enabling impurities such as welding slag to be more evenly sucked from the dust suction ports. At the same time, a plurality of symmetric dust suction ports contribute to forming a more stable air flow field. When impurities such as welding slag are sucked into the dust suction ports, the symmetric layout enables the air flow to enter the dust suction hood orderly, which not only helps improve the dust suction efficiency but also reduces the interference of the air flow on the operation of the cleaning member.

[0028] In some embodiments, the dust removal device further includes a limiting mechanism; the limiting mechanism is located on the moving path of the base moving along the first direction.

[0029] In this way, the limit position of the base can be limited, thereby limiting the dust suction hood in the first direction, so that the cleaning member and the dust suction hood maintain a relatively fixed position during operation, reducing the loosening of components caused by factors such as vibration and shaking, and further contributing to improving the stability and reliability of the device.

[0030] In some embodiments, the limiting mechanism is configured to be controllably moved along a preset path, and the preset path is the moving path of the base moving in the first direction.

[0031] In this way, the position of the dust removal assembly in the first direction can be determined according to the part to be cleaned, and the position of the limiting mechanism can be determined according to this position, and then the limiting mechanism is fixed at the corresponding position to limit the base. In this way, the limiting position can be flexibly adjusted according to different cleaning tasks and the conditions of the parts to be cleaned. Thereby, not only the adaptability of cleaning is improved, but also the reliability of the overall device is further enhanced.

[0032] In some embodiments, the dust removal device further includes a buffer mechanism; the buffer mechanism is located on the moving path of the base moving in the first direction, and the buffer mechanism is configured to buffer when the base moves towards the limiting mechanism.

[0033] In this way, by setting the buffer mechanism, when the base moves towards the limiting mechanism, the buffer mechanism can play a buffering role between the two, which can not only protect each component, but also contribute to improving the smoothness of the base movement.

[0034] In some embodiments, the dust removal device further includes a detection mechanism, and the detection mechanism is configured to detect the displacement of the base in the first direction; the second driving mechanism can adjust the displacement of the base in the first direction in response to the detection signal of the detection mechanism.

[0035] In this way, by setting the detection mechanism, the second driving mechanism can control the displacement of the base, so that the movement of the base is more reliable and stable.

[0036] In some embodiments, the dust removal device further includes an adjustment mechanism; the dust suction hood is connected to the base by means of the adjustment mechanism, and the adjustment mechanism is configured to be able to adjust the distance between the dust suction hood and the base in the first direction.

[0037] In this way, when the dust suction hood reaches the corresponding position under the drive of the second driving mechanism, the position of the dust suction hood in the first direction can be further adjusted by means of the adjustment mechanism, so that the dust suction hood can be close to or far from the part to be cleaned, and the distance between the dust suction port and the part to be cleaned can be further made appropriate, thereby improving the dust suction effect. In this way, the adjustment mechanism can be used to compensate for the possible driving error of the second driving mechanism.

[0038] In some embodiments, the dust removal device further includes a guiding member disposed on the base and within the dust suction hood; the guiding member is arranged in cooperation with the cleaning member and is configured to guide the movement of the cleaning member in the first direction.

[0039] In this way, on the one hand, the guiding member can guide the movement of the cleaning member in the first direction, which is beneficial for the cleaning member to move along the required path; on the other hand, due to the constraint and support of the guiding member, not only is the cleaning member more stable during movement, but also the cleaning member can be more stable when cleaning the welding slag, thus being beneficial to improving the cleaning effect.

With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing.

[0074] In the present application, the battery cell may include a lithium-ion battery, a sodium-ion battery, a magnesium-ion battery device, etc., and the embodiments of the present application do not limit this. The battery cell can be in the shape of a cylinder, a flat body, a cuboid, or other shapes, and the embodiments of the present application do not limit this either.

[0075] Figure 1 It is a partial exploded structural schematic diagram of a battery cell in some embodiments of the present application. The battery cell 10 refers to the smallest unit that makes up the battery device. As Figure 1 , the battery cell 10 includes a housing 11, an electrode assembly 12, and other functional components.

[0076] The housing 11 is a component for forming the internal environment of the battery cell 10. The housing 11 may include a housing body 11a and an end cap 11b. The housing body 11a is a component for cooperating with the end cap 11b to form the internal environment of the battery cell 10. Among them, the formed internal environment can be used to accommodate the electrode assembly 12, the electrolyte (not shown in the figure), and other components. The housing body 11a and the end cap 11b can be independent components. An opening can be provided on the housing body 11a, and the end cap 11b can be covered at the opening to form the internal environment of the battery cell 10. Without limitation, the end cap 11b and the housing body 11a can also be integrated. The housing body 11a can be in various shapes and sizes, such as cuboid, cylindrical, hexagonal prism, etc. Specifically, the shape of the housing body 11a can be determined according to the specific shape and size of the electrode assembly 12. The material of the housing body 11a can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not make special restrictions on this. The opening of the housing body 11a can be located on the side or bottom of the housing body 11a, and the embodiments of the present application do not limit this.

[0077] The end cap 11b refers to a component that can cover the opening of the housing 11a to isolate the internal environment of the battery cell 10 from the external environment. Without limitation, the shape of the end cap 11b can be adapted to the shape of the housing 11a to fit the housing 11a. For example, the end cap 11b can be made of a material with a certain hardness and strength (such as aluminum alloy). In this way, the end cap 11b is not easily deformed when subjected to extrusion and collision, enabling the battery cell 10 to have higher structural strength and improved safety performance. Functional components such as electrode terminals can be provided on the end cap 11b. The electrode terminals can be used for electrical connection with the electrode assembly 12 to output or input the electrical energy of the battery cell 10. In some embodiments, a liquid injection hole can be provided on the end cap 11b for injecting electrolyte into the interior of the battery cell 10. Of course, the electrode terminals and the liquid injection hole can also be provided on the housing 11a. The material of the end cap 11b can also be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not make special restrictions on this. In some embodiments, a pressure relief mechanism can also be provided on the housing 11a and / or the end cap 11b. The pressure relief mechanism is used to release the internal pressure when the internal pressure or temperature of the battery cell 10 reaches a threshold value to improve the safety performance of the battery cell 10. The threshold design varies according to different design requirements.

[0078] The electrode assembly 12 is a component in the battery cell 10 where an electrochemical reaction occurs. The housing 11 can contain one or more electrode assemblies 12. The electrode assembly 12 is mainly formed by laminating a positive electrode plate and a negative electrode plate, and usually an isolator is provided between the positive electrode plate and the negative electrode plate. The parts of the positive electrode plate and the negative electrode plate with active substances constitute the main body of the electrode assembly 12, and the parts of the positive electrode plate and the negative electrode plate without active substances respectively constitute the electrode tabs. The positive electrode tab and the negative electrode tab can be located at one end of the main body together or at both ends of the main body respectively, can be located at the top of the main body, or can be located on the side wall of the main body, and no specific limitation is made here. During the charging and discharging process of the battery device, the positive electrode active substance and the negative electrode active substance react with the electrolyte, and the electrode tabs are connected to the electrode terminals to form a current loop. The isolator is used to isolate the positive electrode plate and the negative electrode plate and prevent electrons in the battery cell 10 from freely passing through, allowing ions in the electrolyte to flow freely between the positive electrode plate and the negative electrode plate. The isolator can be a thin film component made of materials such as PE (polyethylene) and PP (polypropylene).

[0079] The battery cell 10 further includes a current collector plate 13. The current collector plate 13 is a component for connecting the tabs of the electrode assembly 12 in the housing 11 and connecting the terminal posts. The current collector plate 13 and the tabs are usually connected by welding. The part of the current collector plate 13 covering the opening of the housing 11a of the battery cell 10 can be set to a shape adapted to the shape of the opening of the housing 11a of the battery cell 10, such as a circle. At the same time, the current collector plate 13 can be welded to the tabs of the electrode assembly 12 by welding. Among them, the area and position of the welding area of the current collector plate 13 can be set appropriately according to the needs of welding the tabs. In addition, the shape of the welding area of the current collector plate 13 is not limited and can be determined according to specific circumstances.

[0080] In the process of battery production, welding is an important link. Taking the welding of the current collector plate and the tabs as an example, substances such as welding slag are generated during the welding process of the current collector plate and the tabs. The existence of welding slag will affect the use effect or service life of the battery. Therefore, the cleaning of welding slag after welding is a technical problem that needs to be solved urgently.

[0081] To improve at least some of the above problems, the embodiments of the present application provide a dust removal device and a battery production device, which improve the driving mode of the dust removal component to improve the cleaning effect of substances such as welding slag, thereby improving the use effect and service life of the battery.

[0082] It should be noted that the dust removal device disclosed in the embodiments of the present application can be but is not limited to being used in battery cells in the shape of a cylinder, a flat body, a cuboid or other shapes.

[0083] According to some embodiments of the present application, please refer to Figure 2 and Figure 3 , Figure 2 is a schematic three-dimensional structure diagram of a dust removal device 100 provided by some embodiments of the present application, Figure 3 is a schematic front view structure diagram of a dust removal device 100 provided by some embodiments of the present application. The embodiments of the present application provide a dust removal device 100, which includes a base 110, a dust removal component 120, a first driving mechanism 130 and a second driving mechanism 140. The dust removal component 120 includes a dust suction hood 121 and a cleaning member 122. The dust suction hood 121 is arranged on the base 110, and the cleaning member 122 is movably arranged in the dust suction hood 121. The cleaning member 122 is configured to clean the welding slag on the battery cell preform. The first driving mechanism 130 is arranged on the base 110. The first driving mechanism 130 is connected to the cleaning member 122, and the first driving mechanism 130 is configured to be able to drive the cleaning member 122 to move along the first direction F1. The second driving mechanism 140 is connected to the base 110, and the second driving mechanism 140 is configured to be able to drive the base 110 to move along the first direction F1.

[0084] Among them, the base 110 is a basic component for supporting, fixing, or carrying relevant components in the dust removal device 100. The relevant components include a dust removal assembly 120, a first driving mechanism 130, a second driving mechanism 140, etc.

[0085] The dust removal assembly 120 is a combination of relevant components for removing impurities such as welding slag. The dust suction hood 121 is mainly a component for collecting the removed impurities such as welding slag. The dust suction hood 121 can isolate the welding slag and other impurities from the surrounding environment and guide the removed welding slag and other impurities into the dust suction system. Exemplarily, the dust suction hood 121 can cooperate with a negative pressure generating member (such as a fan), utilize the negative pressure generated by the negative pressure generating member to suck out the welding slag and other impurities, and then the welding slag and other impurities can be conveyed to the corresponding component through a pipeline connected to the dust suction hood 121. The cleaning member 122 is a component for cleaning the welding slag. The cleaning member 122 is movably disposed in the dust suction hood 121, that is, the cleaning member 122 is movable relative to the dust suction hood 121, and the position of the cleaning member 122 in the dust suction hood 121 can change. A battery cell preform refers to an intermediate form of a battery cell. For example, it can be a structure after the current collector plate and the tab are welded.

[0086] The first driving mechanism 130 and the second driving mechanism 140 are mechanisms for providing driving force. Both the first driving mechanism 130 and the second driving mechanism 140 are used to output linear motion. The first driving mechanism 130 is used to provide driving force for the movement of the cleaning member 122 along the first direction F1. The first driving mechanism 130 can be various mechanisms that can output linear motion. For example, the first driving mechanism 130 can be a linear motor, a cylinder, or a hydraulic cylinder, etc. The first driving mechanism 130 can transmit power to the cleaning member 122 through a transmission device, or can also transmit power to the cleaning member 122 without passing through a transmission device, and no specific limitation is made here. The second driving mechanism 140 is used to provide driving force for the movement of the base 110 along the first direction F1. Similar to the first driving mechanism 130, the second driving mechanism 140 can also be composed of various power sources and transmission devices, and no specific limitation is made here.

[0087] By setting the first driving mechanism 130 to drive the cleaning member 122 in the dust removal assembly 120 to move along the first direction F1, and by setting the second driving mechanism 140 to drive the entire dust removal assembly 120 to move along the first direction F1. In this way, the positions of the dust suction hood 121 and the cleaning member 122 in the first direction F1 can be adjusted more flexibly, so that the positions of the dust suction hood 121 and the cleaning member 122 relative to the component to be cleaned in the first direction F1 can be adjusted according to the surface of the component to be cleaned. Thus, while the cleaning member 122 is convenient for cleaning welding slag, the dust suction hood 121 is convenient for sucking the welding slag, thereby improving the cleaning effect of the welding slag, and improving the use effect and service life of the battery. In addition, since the second driving mechanism 140 can quickly move the overall component to a rough position, and the first driving mechanism 130 can adjust the position of the cleaning member 122, the efficiency of removing welding slag can be improved.

[0088] It should be noted that taking a cylindrical battery cell as an example, the surface of the current collector plate of the cylindrical battery cell is usually uneven, with grooves and protrusions on the surface of the current collector plate. As a result, when the cleaning member 122 is cleaning the welding slag, it is difficult to control the pressure acting on the surface of the current collector plate, and impurities such as welding slag separated from the current collector plate are likely to splash. In the embodiment of the present application, since the position of the cleaning member 122 relative to the dust suction hood 121 can be controlled by the first driving mechanism 130, and the position of the dust suction hood 121 relative to the part to be cleaned can be controlled by the second driving mechanism 140, the positions of the dust suction hood 121 and the cleaning member 122 can be controlled according to the surface shape of the current collector plate. Thus, while adjusting the pressure of the cleaning member 122 acting on the current collector plate, impurities such as the cleaned welding slag can be sucked by the dust suction hood 121, thereby improving the cleaning efficiency and cleaning effect. In this way, the entry of welding slag into the electrode assembly can be improved, and the risk of short circuit caused by the connection of the positive electrode plate and the negative electrode plate can be reduced, thereby improving the quality and safety performance of the battery.

[0089] According to some embodiments of the present application, please continue to refer to Figure 2 and Figure 3 , and in combination with reference to Figure 4 , Figure 4 is a cross-sectional structural schematic diagram of a part of the structure of the dust removal device 100 provided by some embodiments of the present application. The dust removal device 100 further includes a third driving mechanism 150. The third driving mechanism 150 is connected between the first driving mechanism 130 and the cleaning member 122. The third driving mechanism 150 is configured to be able to drive the cleaning member 122 to rotate around the first axis L1. The extending direction of the first axis L1 and the first direction F1 are parallel to each other.

[0090] The third driving mechanism 150 is a mechanism for providing driving force, and the third driving mechanism 150 is used to output rotational motion. The third driving mechanism 150 is connected to the first driving mechanism 130 and the cleaning member 122, which means that the third driving mechanism 150 integrates its own rotational motion with the motion of the first driving mechanism 130 and transmits it to the cleaning member 122. The third driving mechanism 150 can convert and combine different forms of motion according to the working requirements. The third driving mechanism 150 and the first driving mechanism 130 can be interrelated and work together. For example, during the cleaning process, according to the specific conditions of the surface of the current collector plate and the specific connection forms of the third driving mechanism 150, the first driving mechanism 130, and the cleaning member 122, the actions of the first driving mechanism 130 and the third driving mechanism 150 can be controlled to enable the cleaning member 122 to perform cleaning in the required motion mode.

[0091] By providing the third driving mechanism 150, the cleaning member 122 can rotate, so that the cleaning member 122 can rotate after reaching the required position, thereby cleaning the welding slag. Since the rotating cleaning member 122 can continuously contact the welding slag, the welding slag can be cleaned more quickly based on the centrifugal force and frictional force generated by the cleaning member 122. It can be understood that when the surface of the current collector plate is uneven, the surface of the current collector plate is more likely to accumulate welding slag particles, and due to the deeper welding molten pool, the adhesion between the welding slag and the current collector plate is also greater, and it is easier to have the situation of splashing of the cleaned welding slag. Using the rotating cleaning member 122 to clean the welding slag, since the rotating method can make the pressure exerted by the cleaning member 122 on the current collector plate more uniform, not only can the welding slag be cleaned more quickly, but also the situation of splashing of the cleaned welding slag can be improved and the risk of damage to the surface of the current collector plate by the cleaning member 122 can be reduced.

[0092] According to some embodiments of the present application, please continue to refer to Figure 4 , the third driving mechanism 150 includes a driving member 151, a first rotating member 152, and a second rotating member 153. The driving member 151 is disposed on the base 110. The first rotating member 152 is connected to the driving member 151, and the driving member 151 is configured to be able to drive the first rotating member 152 to rotate around the second axis L2. The second axis L2 and the first axis L1 are parallel to each other. The second rotating member 153 is adapted to be meshed and connected with the first rotating member 152, and the second rotating member 153 can generate rotation around the first axis L1 in response to the rotation of the first rotating member 152. Wherein, the second rotating member 153 has a first side s1 and a second side s2 oppositely arranged in the first direction F1, the first side s1 of the second rotating member 153 is rotatably connected to the first driving mechanism 130, and the second side s2 of the second rotating member 153 is connected to the cleaning member 122.

[0093] By configuring the third driving mechanism 150 to include a driving member 151, a first rotating member 152, and a second rotating member 153, and the first rotating member 152 and the second rotating member 153 can be meshed and connected, the rotational motion output by the driving member 151 is output to the cleaning member 122 via the first rotating member 152 and the second rotating member 153. Since the first rotating member 152 and the second rotating member 153 are driven by meshing connection, the cleaning member 122 can rotate more continuously and stably during the cleaning process, which can reduce power fluctuations and thus improve the cleaning quality. Since the first driving mechanism 130 and the second rotating member 153 are rotatably connected, when the first driving mechanism 130 outputs a linear motion, the meshing teeth of the first rotating member 152 and the second rotating member 153 can be used to guide the movement of the second rotating member 153 along the first direction F1, so that the cleaning member 122 can move more accurately along the first direction F1 under the drive of the second rotating member 153, which is beneficial to controlling the position of the cleaning member 122 and further beneficial to cleaning the welding slag at different positions. At the same time, by arranging the first rotating member 152 and the second rotating member 153, not only can the driving member 151 be installed at a more appropriate position, but also it can cooperate with the first driving mechanism 130 to realize the coexistence of two motion modes, namely linear motion and rotational motion, thus improving the overall compactness and space utilization rate of the device.

[0094] Of course, in some other embodiments, the third driving mechanism 150 can also be a driving motor. Specifically, the output end of the first driving mechanism 130 is connected to the driving motor. The output end of the first driving mechanism 130 is used to output a linear motion, and the first driving mechanism 130 is configured to be able to drive the driving motor to move along the first direction F1. The output end of the driving motor is used to output a rotational motion, and the output end of the driving motor rotates around the central axis on its axis. The output end of the driving motor is connected to the cleaning member 122, and the central axis of the output end of the driving motor, the central axis of the cleaning member 122, and the first axis L1 coincide with each other in pairs. In this way, the rotational motion output by the output end of the driving motor can be directly transmitted to the cleaning member 122, enabling the cleaning member 122 to rotate around the first axis L1. It can be understood that compared with the way of configuring the third driving mechanism 150 as a driving motor, configuring the third driving mechanism 150 to include a driving member 151, a first rotating member 152, and a second rotating member 153 is more beneficial to improving the overall compactness and space utilization rate of the device, and is also beneficial to improving the rotational stability of the cleaning member 122.

[0095] According to some embodiments of the present application, please continue to refer to Figure 4 and, in combination with referring to Figure 5 Figure 5Schematic diagram of the structure in which the first rotating member 152 and the second rotating member 153 provided in some embodiments of the present application cooperate. The first rotating member 152 includes a first rotating portion 152a and a plurality of first tooth portions 152b. The first rotating portion 152a is connected to the driving member 151, and the plurality of first tooth portions 152b are arranged around the second axis L2 on the outer peripheral surface of the first rotating portion 152a. The second rotating member 153 includes a second rotating portion 153a and a plurality of second tooth portions 153b. The plurality of second tooth portions 153b are arranged around the first axis L1 on the outer peripheral surface of the second rotating portion 153a, and the second tooth portion 153b is adapted to mesh with the first tooth portion 152b. Wherein, along the first direction F1, the size of the first tooth portion 152b is greater than the size of the second tooth portion 153b; or, along the first direction F1, the size of the first tooth portion 152b is less than the size of the second tooth portion 153b.

[0096] Exemplarily, taking Figure 4 and Figure 5 as an example, along the first direction F1, the size of the first tooth portion 152b is the first size d1, and the size of the second tooth portion 153b is the second size d2. The first size d1 is less than the second size d2. Of course, the first size d1 can also be greater than the second size d2. The difference between the first size d1 and the second size d2 can be set according to the required stroke, and no specific limitation is made here.

[0097] By controlling the sizes of the first tooth portion 152b and the second tooth portion 153b along the first direction F1, the movement of the cleaning member 122 can be realized by using the entire thickness range of the corresponding tooth portion, thereby effectively increasing the effective stroke of the cleaning member 122 moving along the first direction F1. In this way, there is no need to additionally occupy a large amount of space to set up a complex guiding structure, and the movement of the cleaning member 122 along the first direction F1 is realized in a relatively compact space, further improving the space utilization rate.

[0098] According to some embodiments of the present application, please refer to Figure 6 , Figure 6 Schematic diagram of the cleaning member 122 provided in some embodiments of the present application from a perspective. Figure 6 The perspective shown is Figure 5 the upward perspective from the perspective shown. The cleaning member 122 includes a seat body 122a and at least one brush unit 122b. The seat body 122a has a first surface m1 and a second surface m2 that are oppositely arranged along the first direction F1. The first surface m1 is connected to the first driving mechanism 130, and the second surface m2 is provided with the brush unit 122b. A gap space G is defined between the second surface m2 and the brush unit 122b.

[0099] The brush unit 122b refers to an aggregate formed by aggregating or combining multiple brushes. The brushes are usually made of bristle materials with certain elasticity and wear resistance. The bristle materials can be nylon, etc., without specific limitation here. Parameters such as the length, hardness, and density of the bristles are selected according to different usage scenarios and requirements. Since the brushes have certain elasticity, when the brush unit 122b is pressed against the part to be cleaned, the brushes can deform, and when the brush unit 122b leaves the part to be cleaned, the brushes can recover their deformation. The number of brush units 122b can be one, two, three, five, or other numbers, without specific limitation here.

[0100] By defining a clearance space G between the second surface m2 and the brush unit 122b, not only can a deformation space be provided for the brush unit 122b, which is beneficial for cleaning the welding slag, but also more diffusion space is provided for the impurities such as the welding slag to be cleaned, and more disturbances can be generated when the air flow passes through the clearance space G, which further facilitates the detachment of impurities such as the welding slag from the brush unit 122b and is beneficial for dust removal operation by means of the dust suction hood 121, thereby improving the welding slag cleaning effect and the dust removal effect.

[0101] It can be understood that compared with the case where the brush units 122b are all provided on the second surface m2 of the seat body 122a, since the clearance space G is defined between the second surface m2 and the brush unit 122b, the surface of the part to be cleaned opposite to the seat body 122a is not completely covered by the brush units 122b, so as described above, it is beneficial to improve the welding slag cleaning effect and the dust removal effect.

[0102] According to some embodiments of the present application, please continue to refer to Figure 6 that multiple brush units 122b are provided, the brush units 122b are longitudinally extended and arranged on the second surface m2, and the brush unit 122b has a first end e1 and a second end e2 that are oppositely arranged along the longitudinal direction of the brush unit 122b. The first ends e1 of all the brush units 122b are connected, and the second ends e2 of all the brush units 122b are arranged at intervals around the central axis of the seat body 122a. The extending direction of the central axis of the seat body 122a and the first direction F1 are parallel to each other.

[0103] The central axis of the seat body 122a may coincide with the first axis L1 or have a spacing therebetween, which is not specifically limited herein. In the embodiments of the present application, a situation where the central axis of the seat body 122a coincides with the first axis L1 is illustrated. The brush unit 122b extends longitudinally on the second surface m2, that is, the orthographic projection of the brush unit 122b on the second surface m2 can be generally regarded as a longitudinal member. Since the first ends e1 of all the brush units 122b are connected, the second ends e2 of all the brush units 122b are arranged at intervals around the central axis of the seat body 122a. Along the circumferential direction of the seat body 122a, an interval may be formed between two adjacent brush units 122b, so that the brush units 122b can be generally arranged in a radial pattern.

[0104] In this way, it is not only beneficial to make all the brush units 122b form a larger coverage area, facilitating the cleaning of welding slag, but also can minimize the space occupied by the brush units 122b as much as possible, thereby being beneficial to improving the dust removal effect.

[0105] According to some embodiments of the present application, please continue to refer to Figure 6 , the connection part of the first ends e1 of all the brush units 122b defines a junction H, and the center of the junction H is located on the central axis of the seat body 122a.

[0106] Exemplarily, taking Figure 6 as an example and in combination with referring to Figure 3 and Figure 4 , the center of the junction H is the center point C, and the center point C is located on the first axis L1.

[0107] In this way, the force can be more effectively transmitted and distributed to each brush unit 122b, and the forces received by each brush unit 122b are relatively balanced, improving the overall mechanical performance and reliability of the brush, and thus being beneficial to improving the cleaning effect.

[0108] According to some embodiments of the present application, please continue to refer to Figure 6 , the connection part of the first ends e1 of all the brush units 122b defines a junction H, and all the brush units 122b are symmetrically arranged about the center of the junction H.

[0109] In this way, it is not only beneficial to enhance the stability of the structure, but also beneficial to improving the consistency of the cleaning effect.

[0110] Of course, in some other embodiments, all the brush units 122b may not be symmetrically arranged about the center of the junction H, which is not specifically limited herein.

[0111] According to some embodiments of the present application, please continue to refer to Figure 6 , there are four brush units 122b provided.

[0112] Exemplarily, taking Figure 6 as an example, the four brush units 122b generally form a "cross" shape.

[0113] In this way, while minimizing the space occupied by the brush unit 122b as much as possible, the cleaning effect of the cleaning member 122 and the dust removal effect of the dust suction member can be improved.

[0114] Of course, in some other embodiments, the number of brush units 122b can also be set to six, eight, etc. When there are eight brush units 122b, the eight brush units 122b can generally form a "rice" shape. There is no specific limitation here.

[0115] According to some embodiments of the present application, please continue to refer to Figure 6 , the longitudinal direction of the brush unit 122b is a straight line direction; or, the longitudinal direction of the brush unit 122b is a curved line direction.

[0116] Exemplarily, taking Figure 6 as an example, the situation where the longitudinal direction of the brush unit 122b is a straight line direction is shown.

[0117] When the longitudinal direction of the brush unit 122b is a straight line direction, it is not only beneficial for manufacturing, but also beneficial for more evenly transmitting force to each part, improving the stability of the cleaning strength, and enhancing the cleaning effect. When the longitudinal direction of the brush unit 122b is a curved line direction, it can not only better fit the surfaces of various complex shapes, but also when the brush unit 122b encounters obstacles or uneven surfaces, it can buffer the impact force through its own bending structure, reducing damage to the brush unit 122b and the object to be cleaned. The longitudinal direction of the brush unit 122b can be flexibly set, and there is no specific limitation here.

[0118] According to some embodiments of the present application, please continue to refer to Figures 2 to 4 , the dust suction hood 121 has a peripheral side wall 121a arranged around the central axis of the cleaning member 122, and a dust suction port k is provided on the peripheral side wall 121a of the dust suction hood 121. The extending direction of the central axis of the cleaning member 122 and the first direction F1 are parallel to each other.

[0119] The central axis of the cleaning member 122 can coincide with the first axis L1 or not. In the embodiments of the present application, taking Figure 3 and Figure 4 as examples, the situation where the central axis of the cleaning member 122 coincides with the first axis L1 is shown. The dust suction port k communicates with the inside of the dust suction hood 121. As shown in the situations in the foregoing some embodiments, the dust suction port k can be connected to the inside of the corresponding negative pressure generating member.

[0120] Since the peripheral side wall 121a of the dust cover 121 is arranged around the central axis of the cleaning member 122, the dust suction port k is distributed around the cleaning member 122, which is conducive to the suction of impurities such as welding slag and improves the dust suction efficiency. At the same time, the cleaning member 122 will drive the surrounding air flow to form an airflow when working, so that the dust suction port k can suck in impurities such as welding slag, thereby improving the dust suction effect.

[0121] According to some embodiments of this application, please continue to refer to Figures 2 to 4 There are multiple dust suction ports k, and all of the dust suction ports k are symmetrically arranged on the peripheral side wall 121a of the dust suction cover 121 about the central axis of the cleaning member 122.

[0122] Exemplarily, the number of the suction ports k can be set to two, four or other numbers, which are not specifically limited herein.

[0123] Since the dust suction ports k are symmetrically arranged, a more stable dust suction area can be formed around the cleaning member 122, so that impurities such as welding slag can be more evenly sucked out from the dust suction ports k. At the same time, multiple symmetrical dust suction ports k help to form a more stable airflow flow field. When impurities such as welding slag are sucked into the dust suction ports k, the symmetrical layout allows the airflow to enter the dust hood 121 in an orderly manner, which is not only conducive to improving the dust suction efficiency, but also reduces the interference of the airflow on the operation of the cleaning member 122.

[0124] It should be noted that, in the situations illustrated in some of the aforementioned embodiments, when the brush unit 122b is symmetrically arranged about the central axis of the base body 122a, combined with the symmetrical arrangement of the dust suction port k about the center of the cleaning piece 122, the structure of the dust suction hood 121 can be coordinated with the structure of the cleaning piece 122, which is more conducive to improving the dust removal effect while improving the cleaning quality.

[0125] According to some embodiments of this application, please continue to refer to Figure 2 and Figure 3 The dust removal device 100 further includes a limiting mechanism 160. The limiting mechanism 160 is located on a moving path of the base 110 moving along the first direction F1.

[0126] The limiting mechanism 160 can be a limiting structure such as a limiting plate, a limiting block, etc., and is not specifically limited here.

[0127] In this way, the extreme position of the base 110 can be limited, thereby limiting the dust hood 121 in the first direction F1, so that the cleaning piece 122 and the dust hood 121 maintain a relatively fixed position during operation, reducing the loosening of components caused by vibration, shaking and other factors, thereby helping to improve the stability and reliability of the device.

[0128] According to some embodiments of this application, please continue to refer to Figure 2and Figure 3 The limiting mechanism 160 is configured to be controllably moved along a preset path, and the preset path is the moving path of the base 110 moving along the first direction F1.

[0129] Exemplarily, the limiting mechanism 160 can be a bolt assembly. The dust removal device 100 further includes a mounting base Z. The limiting mechanism 160 is detachably connected to the mounting base Z. By rotating and adjusting the screw in the bolt assembly and fixing the screw with the nut in the bolt assembly, the position of the screw in the first direction F1 can be adjusted.

[0130] In this way, the position of the dust removal assembly 120 in the first direction F1 can be determined according to the part to be cleaned, and then the position of the limiting mechanism 160 can be determined according to this position, and the limiting mechanism 160 can be fixed at the corresponding position to limit the base 110. In this way, the limiting position can be flexibly adjusted according to different cleaning tasks and the conditions of the parts to be cleaned. Thereby, not only the adaptability of cleaning is improved, but also the reliability of the overall device is further enhanced.

[0131] According to some embodiments of the present application, please continue to refer to Figure 2 and Figure 3 The dust removal device 100 further includes a buffer mechanism 170. The buffer mechanism 170 is located on the moving path of the base 110 moving along the first direction F1, and the buffer mechanism 170 is configured to buffer when the base 110 moves towards the limiting mechanism 160.

[0132] The buffer mechanism 170 is a device for slowing down or absorbing impact force. Exemplarily, the buffer mechanism 170 can be a spring buffer component, a hydraulic buffer component, a pneumatic buffer component or a rubber buffer component, etc., which are not specifically limited herein.

[0133] In this way, by setting the buffer mechanism 170, when the base 110 moves towards the limiting mechanism 160, the buffer mechanism 170 can play a buffering role between the two, which can not only protect each component, but also contribute to improving the smoothness of the movement of the base 110.

[0134] According to some embodiments of the present application, please continue to refer to Figure 2 and Figure 3 The dust removal device 100 further includes a detection mechanism J, and the detection mechanism J is configured to detect the displacement of the base 110 along the first direction F1. The second driving mechanism 140 can adjust the displacement of the base 110 along the first direction F1 in response to the detection signal of the detection mechanism J.

[0135] Exemplarily, the detection mechanism J can be a displacement sensor. It is not specifically limited herein.

[0136] Thus, by providing the detection mechanism J, the second driving mechanism 140 can control the displacement of the base 110, making the movement of the base 110 more reliable and stable.

[0137] According to some embodiments of the present application, please continue to refer to Figures 2 to 4 , the dust removal device 100 further includes an adjusting mechanism 180. The dust suction hood 121 is connected to the base 110 by means of the adjusting mechanism 180, and the adjusting mechanism 180 is configured to be able to adjust the distance between the dust suction hood 121 and the base 110 along the first direction F1.

[0138] Exemplarily, the adjusting mechanism 180 may include a cylinder 181 and a connecting member 182. The cylinder 181 is connected to the base 110, and the dust suction hood 121 is disposed within the cylinder 181. The connecting member 182 may be a bolt assembly. A strip-shaped hole extending along the first direction F1 may be formed in the cylinder 181, and a through hole corresponding to the strip-shaped hole may be formed in the dust suction hood 121. The connecting member 182 may pass through the through hole and the strip-shaped hole to fixedly connect the cylinder 181 and the connecting member 182. By adjusting the position of the connecting member 182 relative to the strip-shaped hole, the position of the dust suction hood 121 can be adjusted.

[0139] Thus, when the dust suction hood 121 reaches the corresponding position under the drive of the second driving mechanism 140, the position of the dust suction hood 121 in the first direction F1 can be further adjusted by means of the adjusting mechanism 180, enabling the dust suction hood 121 to approach or move away from the part to be cleaned, further ensuring that a proper distance is maintained between the dust suction port k and the part to be cleaned, thereby improving the dust suction effect. In this way, the adjusting mechanism 180 can be used to compensate for possible driving errors of the second driving mechanism 140.

[0140] According to some embodiments of the present application, please continue to refer to Figure 4 , the dust removal device 100 further includes a guiding member 190. The guiding member 190 is disposed on the base 110 and within the dust suction hood 121. The guiding member 190 is configured to cooperate with the cleaning member 122 and is configured to guide the movement of the cleaning member 122 along the first direction F1.

[0141] Exemplarily, with reference to Figure 4 , the cleaning member 122 further includes a connecting rod 122c. The connecting rod 122c connects the second rotating member 153 and the seat body 122a of the cleaning member 122. The guiding member 190 may be sleeved outside the connecting rod 122c. Of course, the guiding member 190 may also be other guiding structures, which are not specifically limited herein.

[0142] Thus, on the one hand, the guiding member 190 can guide the movement of the cleaning member 122 along the first direction F1, which is beneficial to making the cleaning member 122 move along the required path; on the other hand, due to the restraint and support of the guiding member 190, not only is the cleaning member 122 more stable during movement, but also the cleaning member 122 can be more stable when cleaning the welding slag, thereby being beneficial to improving the cleaning effect.

[0143] According to some embodiments of the present application, please continue to refer to Figure 2 and Figure 3 , the dust removal device 100 further includes a mounting base Z, a moving base Y, and a guide rail W. The second driving mechanism 140 and the guide rail W are provided on the mounting base Z. The moving base Y is movably connected to the guide rail W along the first direction F1, and the second driving member 151 is connected to the moving base Y. The moving base Y is connected to the base 110.

[0144] In this way, the second driving member 151 can drive the moving base Y to move in the first direction F1, thereby driving the base 110 to move along the first direction F1. Thus, not only can the movement of the base 110 be more stable, but also it is beneficial to arranging the components of the dust removal device 100, making the whole more compact.

[0145] It should be noted that, in combination with referring to Figure 3 , the limiting mechanism 160, the buffering mechanism 170, and the detection mechanism J shown in the foregoing some embodiments can all be provided on the mounting base Z. The limiting mechanism 160 can limit the moving base Y, the buffering mechanism 170 can buffer the moving base Y, and the detection mechanism J can detect the displacement of the moving base Y. Since the moving base Y is connected to the base 110, in this way, the base 110 can be respectively limited, buffered, and displacement-detected in the first direction F1.

[0146] According to some embodiments of the present application, the present application provides a battery production device, including the dust removal device 100 in any of the above embodiments.
