Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a rust prevention device and a battery production line. Background Technology

[0002] The nickel plating process used on the battery cell casing effectively prevents the steel casing from rusting. However, during the end cap welding process, the laser welding of the end cap to the casing damages the nickel plating layer at the weld, leading to rust formation at the weld lines. To prevent rusting, rust-preventive devices are typically used to treat the weld areas.

[0003] The rust prevention devices in the relevant technologies cannot effectively treat rusted areas during use, resulting in poor rust prevention performance. Summary of the Invention

[0004] In view of the above problems, this application provides a rust prevention device and a battery production line, which can solve the problem that existing rust prevention devices cannot effectively treat rusted areas and have poor rust prevention effect during use.

[0005] To solve the above-mentioned technical problems, this application proposes a rust prevention device, comprising:

[0006] A clamping assembly includes a movable base, a first driving member, and a second driving member; the first driving member and the second driving member are both connected to the movable base, and the first driving member and the second driving member can move closer to or further away from each other; A cleaning assembly, disposed downstream of the clamping assembly, is configured to clean the clamped battery cells; A spraying assembly, located downstream of the cleaning assembly, is configured to spray rust-preventive liquid onto preset locations of the cleaned battery cells. A curing component, disposed downstream of the spraying component, is configured to cure the sprayed rust inhibitor; It also includes a base and a conveying assembly, wherein the movable base, the cleaning assembly, the spraying assembly, the curing assembly and the conveying assembly are all disposed on the same side of the base; The conveying component is connected to the movable seat, and the conveying component is configured to drive the movable seat to move along a preset direction.

[0007] In the technical solution of this application embodiment, the battery cell is clamped by a clamping assembly, and then the battery cell is cleaned by a cleaning assembly to remove welding slag and foreign matter from the surface of the battery cell. After cleaning, a spraying assembly is used to spray rust-preventive liquid onto a preset position on the battery cell, namely the welding area, to fundamentally prevent oxidation and rusting in the area corresponding to the welding area of ​​the battery cell. Finally, a curing assembly is used to cure the sprayed rust-preventive liquid to improve its adhesion and durability on the battery cell, preventing the rust-preventive liquid from falling off or shifting due to vibration or friction during subsequent handling, assembly, or storage. This device has a high degree of automation and can effectively treat areas on the battery cell that are prone to rusting, providing excellent rust prevention and significantly improving the product's appearance quality.

[0008] In some embodiments, the clamping assembly further includes a first support arm, a second support arm, and a rotating component; The first support arm and the second support arm are both fixed to the same side of the movable seat. The first driving member is rotatably connected to the first support arm, and the second driving member is rotatably connected to the second support arm. The rotating member is fixed to the first support arm and connected to the first driving member. The rotating member is configured to drive the first driving member to rotate around a first direction, wherein the first direction is the direction in which the first driving member and the second driving member move closer to or further away from each other.

[0009] In this way, after the first driving member and the second driving member approach each other and clamp the corresponding battery cell, the rotating member drives the first driving member to rotate around the first direction. Since the first driving member is rotatably connected to the first support arm and the second driving member is rotatably connected to the second support arm, when the rotating member drives the first driving member to rotate around the first direction, the battery cell located between the first driving member and the second driving member can be rotated synchronously, which facilitates cleaning and spraying different positions of the battery cell.

[0010] In some embodiments, the clamping assembly further includes a third drive member fixed to the side of the movable seat facing the first support arm; The third driving member is provided with a clamping seat, which is configured to clamp the bottom surface of the battery cell. The third driving member is configured to drive the clamping seat to rotate around a second direction, wherein the second direction intersects with the first direction.

[0011] In this way, after the bottom surface of the battery cell is clamped onto the clamping seat, the clamping seat is driven to rotate around the second direction by the third driving component, thereby synchronously driving the battery cell to rotate around the second direction.

[0012] In some embodiments, the clamping assembly further includes a fourth drive member disposed on the side of the movable seat facing the first support arm, the fourth drive member being configured to fix the battery cell on a third-direction side, wherein the third-direction is perpendicular to the plane formed by the first direction and the second direction.

[0013] In this way, the fourth driving component can be used to easily fix the battery cell on the third-party side.

[0014] In some embodiments, the clamping assembly further includes a movable stage connected to the movable seat on the side facing the first support arm, and a fourth drive member fixed to the movable stage on the side away from the movable seat. The movable stage is configured to drive the fourth drive member to move in the second direction and the third direction.

[0015] In this way, the fourth driving component can be easily moved in the second and third directions by the moving platform, so that the fourth driving component can be adjusted in position, which is beneficial to the fixation of the battery cell.

[0016] In some embodiments, the clamping assembly further includes a first detection element connected to the moving stage, the first detection element being configured to detect the energy of the laser when the battery cell is cleaned using a laser.

[0017] In this way, the energy of the laser can be easily detected when using laser cleaning of the battery cell through the first detection component, thus avoiding damage to the surface of the battery cell caused by excessive energy.

[0018] In some embodiments, the cleaning assembly includes a first bracket and a laser generator, the first bracket being fixed to the base and the laser generator being connected to the first bracket.

[0019] In this way, the laser emitted by the laser generator can quickly clean the battery cells.

[0020] In some embodiments, the cleaning assembly further includes a fifth driving member connected to the first bracket and connected to the laser generator, the fifth driving member being configured to drive the laser generator to move in the second direction.

[0021] In this way, the laser generator is moved in the second direction by the fifth driving component, so as to adjust the position of the laser generator and the battery cell, which is beneficial to cleaning the surface of the battery cell.

[0022] In some embodiments, the cleaning assembly further includes an optical path control component connected to the first bracket, the optical path control component being adapted to the laser generator, and the optical path control component being configured to deflect and scan the emission path of the laser.

[0023] In this way, by controlling the deflection and scanning of the laser emission path through the optical path control component, the laser beam can be driven to scan the cell surface along arbitrary trajectories such as straight lines, reciprocating motion, dot matrix, and planar patterns. This transforms the single laser beam emitted by the laser generator into a planar cleaning spot, replacing the traditional mechanical moving platform and significantly improving the efficiency of laser cleaning. Simultaneously, since the areas on the cell surface requiring cleaning are mostly localized and precise regions, the optical path control component can precisely deflect the laser beam to act only on the areas to be cleaned, avoiding sensitive parts of the cell and preventing thermal damage or physical scratches to non-cleaned areas, thus avoiding impacts on the cell's electrochemical and sealing performance. Furthermore, the high-speed, uniform scanning of the optical path control component ensures a uniform energy distribution of the laser beam in the cell cleaning area, preventing excessively high local energy caused by prolonged single-point laser irradiation and avoiding problems such as melting, deformation, and burn-through of the cell surface substrate.

[0024] In some embodiments, the cleaning assembly further includes a galvanometer airflow protection component connected to the laser generator, the galvanometer airflow protection component being configured to form an airflow protection barrier on the optical path control component.

[0025] Because laser cleaning generates dust, rust, paint chips, and molten residue, these impurities can easily splash onto the lens surface of the optical path control component, causing scratches and contamination, leading to optical path deviation and laser energy attenuation. The galvanometer airflow protection component continuously sprays high-pressure airflow to form an airflow protection barrier in front of the lens of the optical path control component, isolating cleaning debris from the lens, preventing impurities from adhering, and preventing damage to the internal components of the optical path control component from reverse laser reflection during the cleaning process.

[0026] At the same time, the high-pressure airflow acts synchronously with the laser beam on the surface of the battery cell to be cleaned, which can immediately blow away the dirt and debris stripped by the laser, and prevent the debris from being heated and melted onto the surface of the battery cell by the laser, thus improving the cleanliness. Moreover, during laser cleaning, the battery cell will generate high temperature in some areas due to laser irradiation. The airflow of the galvanometer airflow protection component can simultaneously cool down the battery cell processing area, preventing the battery cell from deforming due to high temperature.

[0027] In some embodiments, the rust prevention device further includes a dust collector, and the cleaning assembly further includes a first suction pipe, the first suction pipe being fixed to the first bracket and connected to the dust collector.

[0028] This makes it easy to remove impurities after cleaning using a dust collector.

[0029] In some embodiments, the rust prevention device further includes a second detection element connected to the first bracket, the second detection element being configured to detect the air velocity in the first suction duct.

[0030] In this way, by detecting the corresponding wind speed through the second detection device, it is possible to avoid the dust collector being unable to remove the impurities after cleaning due to the low operating wind speed.

[0031] In some embodiments, the spraying assembly includes a second bracket, a nozzle, and a material box. The second bracket is fixed to the base, and both the nozzle and the material box are connected to the second bracket. The nozzle is connected to the material box via a negative pressure pump.

[0032] In this way, the anti-rust liquid in the material box can be easily delivered to the spray nozzle by the negative pressure pump, so as to spray the welded parts on the battery cell.

[0033] In some embodiments, the spraying assembly further includes a sixth drive member and a seventh drive member, the sixth drive member being connected to the second bracket, the seventh drive member being connected to the sixth drive member, and the seventh drive member being connected to the spray head; The sixth driving member is configured to drive the seventh driving member to move in the first direction, and the seventh driving member is configured to drive the nozzle to move in the second direction.

[0034] In this way, the sixth and seventh driving components work together to move the nozzle in the first and second directions, thereby adjusting the position of the nozzle and facilitating the application of the rust inhibitor.

[0035] In some embodiments, the spraying assembly further includes a first curing component disposed on the seventh drive member, the first curing component being configured to pre-cure the anti-rust liquid sprayed onto the battery cell.

[0036] In this way, the rust inhibitor sprayed on the battery cell is pre-cured by the first curing component, which can prevent the rust inhibitor from shifting due to inertia during the movement of the battery cell.

[0037] In some embodiments, the spraying assembly further includes a sensor disposed on the seventh actuator, the sensor being positioned to match the position of the spray head.

[0038] In this way, the sensor can easily detect the position of the battery cell, preventing the nozzle from colliding with the battery cell during use.

[0039] In some embodiments, the spraying assembly further includes a third detection element connected between the spray nozzle and the negative pressure pump, the third detection element being configured to detect the pressure of the rust inhibitor delivered to the spray nozzle.

[0040] In this way, the pressure of the corresponding rust inhibitor is detected by the third detection component, which avoids the rust inhibitor sprayed from the nozzle being too low.

[0041] In some embodiments, the spraying assembly further includes a fourth detection element connected to the second bracket, the fourth detection element being configured to detect airborne particulate matter.

[0042] In this way, by detecting airborne particulate matter through the fourth detection component, the purity of the internal environment can be ensured during spraying.

[0043] In some embodiments, the spraying assembly further includes a first temperature controller and a heating element configured to heat the rust inhibitor in the cartridge, and the first temperature controller configured to detect the temperature of the rust inhibitor in the cartridge.

[0044] In this way, the temperature of the rust inhibitor in the material box can be easily detected by the first temperature controller, so as to avoid the rust inhibitor being too cold during use, which would affect the spraying effect.

[0045] In some embodiments, the curing assembly includes a third support and a second curing component, the third support being fixed to the base and the second curing component being connected to the third support, the second curing component being configured to cure the anti-rust liquid sprayed on the battery cell.

[0046] In this way, the rust inhibitor sprayed on the battery cell is cured by the second curing component, so as to achieve rapid curing of the rust inhibitor, improve the adhesion and durability of the rust inhibitor, and prevent the rust inhibitor from falling off or shifting due to vibration or friction during subsequent handling, assembly or storage.

[0047] In some embodiments, the curing assembly further includes an eighth drive member connected to the third bracket and connected to the second curing component, the eighth drive member being configured to drive the second curing component to move in the second direction.

[0048] In this way, the second curing component is moved in the second direction by the eighth driving component, so that the position of the second curing component and the battery cell can be easily adjusted, which is conducive to the curing of the rust inhibitor.

[0049] In some embodiments, the curing assembly further includes a fifth detection element connected to the second curing component, the fifth detection element being configured to detect airflow velocity.

[0050] In this way, by detecting the airflow speed in the corresponding area through the fifth detection element, the heat generated by the second curing component during operation can be carried away in a timely and uniform manner, avoiding local overheating that could damage the second curing component.

[0051] In some embodiments, the curing assembly further includes a sixth detection element connected to the third support, the sixth detection element being configured to detect air temperature.

[0052] In this way, the temperature data of the corresponding area is detected by the sixth detection element to avoid the deformation of the cell surface material due to excessive temperature, while excessive temperature will reduce the curing rate.

[0053] In some embodiments, the curing assembly further includes a seventh detection element connected to the third support, the seventh detection element being configured to detect airborne particulate matter.

[0054] In this way, by detecting airborne particulate matter through the seventh testing component, the purity of the internal environment can be ensured during spraying.

[0055] In some embodiments, the curing assembly further includes a second temperature controller connected to the third bracket, the second temperature controller being configured to detect the temperature of the cell surface.

[0056] In some embodiments, the rust prevention device further includes a dust collector, and the curing assembly further includes a second dust suction pipe, which is fixed to the third bracket and connected to the dust collector.

[0057] In this way, dust removal by a dust collector prevents debris from falling onto the anti-rust liquid on the battery cell during the curing process.

[0058] In some embodiments, the rust prevention device further includes a cover connected to the base, wherein the cleaning assembly, the spraying assembly, the curing assembly, and the conveying assembly are all located within the cavity enclosed by the cover and the base.

[0059] In this way, the cooperation between the cover and the base can prevent external debris from affecting the cleanliness of the working areas of the cleaning, spraying, and curing components.

[0060] In some embodiments, the rust prevention device further includes a first isolation component, a second isolation component, and a third isolation component; The first isolation component, the second isolation component, and the third isolation component are all disposed on the base, and the first isolation component, the second isolation component, and the third isolation component are all capable of closing or opening along the first direction; The first isolation component is disposed between the clamping component and the cleaning component, the second isolation component is disposed between the cleaning component and the spraying component, and the third isolation component is disposed between the spraying component and the curing component.

[0061] This effectively isolates the cleaning components, spraying components, and curing components.

[0062] In some embodiments, the rust prevention device further includes a safety protection component disposed on the base and adapted to the clamping assembly; The safety protection component is configured to detect whether an external object enters the working area of ​​the clamping assembly.

[0063] In some embodiments, the cover is provided with at least one switch door, and the switch door is provided with an observation port.

[0064] In some embodiments, the rust prevention device further includes a processor and a status indicator, both of which are mounted on the cover, and the processor is electrically connected to electrical components on the clamping assembly, the cleaning assembly, the spraying assembly, the curing assembly, and the conveying assembly, respectively. The processor is configured to control the status indicator to display different colors when the electrical components are in different states.

[0077] The nickel plating process used on the battery cell casing effectively prevents the steel casing from rusting. However, during the end cap welding process, the laser welding of the end cap to the casing damages the nickel plating layer at the weld, leading to rust formation at the weld lines. Rusting of the battery cell is considered an aesthetic defect, and over time, corrosion can occur at the rusted areas, causing electrolyte leakage. To prevent rusting, rust-preventive devices are typically used to treat the welded areas.

[0078] The rust prevention devices in the relevant technologies cannot effectively treat rusted areas during use, resulting in poor rust prevention performance.

[0079] Based on the above considerations, in order to solve the problem that existing rust prevention devices cannot effectively treat rusted areas and have poor rust prevention effects during use, this application designs a rust prevention device. The rust prevention device includes a clamping component, a cleaning component, a spraying component, a curing component, a base, and a conveying component. The clamping component includes a movable base, a first driving component, and a second driving component. Both the first and second driving components are connected to the movable base and can move closer to or further away from each other. The cleaning component is located downstream of the clamping component and is configured to clean the clamped battery cell. The spraying component is located downstream of the cleaning component and is configured to spray rust-preventive liquid onto a preset position of the cleaned battery cell. The curing component is located downstream of the spraying component and is configured to cure the sprayed rust-preventive liquid. The movable base, cleaning component, spraying component, curing component, and conveying component are all located on the same side of the base. The conveying component is connected to the movable base and is configured to drive the movable base to move along a preset direction.

[0080] In the technical solution of this application embodiment, the battery cell is clamped by a clamping assembly, and then the battery cell is cleaned by a cleaning assembly to remove welding slag and foreign matter from the surface of the battery cell. After cleaning, a spraying assembly is used to spray rust-preventive liquid onto a preset position on the battery cell, namely the welding area, to fundamentally prevent oxidation and rusting in the area corresponding to the welding area of ​​the battery cell. Finally, a curing assembly is used to cure the sprayed rust-preventive liquid to improve its adhesion and durability on the battery cell, preventing the rust-preventive liquid from falling off or shifting due to vibration or friction during subsequent handling, assembly, or storage. This device has a high degree of automation and can effectively treat areas on the battery cell that are prone to rusting, providing excellent rust prevention and significantly improving the product's appearance quality.

[0081] According to some embodiments of this application, such as Figure 3 and combined Figure 4 , Figure 5As shown, this application provides a rust prevention device, which includes a clamping assembly 11, a cleaning assembly 12, a spraying assembly 13, and a curing assembly 14. The clamping assembly 11 is configured to clamp a battery cell and includes a movable base 111, a first driving member 114, and a second driving member 116. Both the first driving member 114 and the second driving member 116 are connected to the movable base 111 and can move closer to or further away from each other. The cleaning assembly 12 is disposed below the clamping assembly 11. The cleaning component 12 is configured to clean the clamped battery cell. The spraying component 13 is located downstream of the cleaning component 12 and is configured to spray anti-rust liquid onto a preset position of the cleaned battery cell. The curing component 14 is located downstream of the spraying component 13 and is configured to cure the sprayed anti-rust liquid. The moving base 111, the cleaning component 12, the spraying component 13, the curing component 14, and the conveying component 15 are all located on the same side of the base 10.

[0083] In this embodiment, both the first driving member 114 and the second driving member 116 can be fixed to the movable base 111 by bolts or snap-fit. The specific method can be determined according to the actual situation, and this embodiment does not limit this.

[0084] In the initial stage, there is a gap between the first driving member 114 and the second driving member 116. The corresponding battery cell can be placed between the first driving member 114 and the second driving member 116 by means of mechanical claws or other components. Subsequently, the first driving member 114 and the second driving member 116 are controlled to move closer to each other to facilitate clamping the corresponding battery cell.

[0085] In this embodiment, the preset position of the battery cell refers to the welding part on the battery cell.

[0086] The preset direction in this embodiment is as follows: Figure 4 The Y-axis direction in the diagram.

[0087] In this embodiment, the conveying component 15 can be a belt conveyor, chain conveyor, etc., and the specific type can be determined according to the actual situation. This embodiment does not limit this.

[0088] In this embodiment, the movable seat 111 can be bolted to the corresponding chain conveyor. During use, the conveying component 15 drives the movable seat 111 to move along the Y-axis so that the battery cell clamped on the movable seat 111 can move to the corresponding cleaning component 12, spraying component 13 or curing component 14, thereby facilitating the cleaning, spraying and curing of the battery cell.

[0089] In use, the battery cell is clamped by the clamping assembly 11, and then the cleaning assembly 12 cleans the battery cell to remove welding slag and foreign matter from its surface. After cleaning, the spraying assembly 13 sprays rust inhibitor onto the preset positions of the battery cell, i.e., the welding areas, to fundamentally prevent oxidation and rusting in the corresponding areas. Finally, the curing assembly 14 cures the sprayed rust inhibitor, improving its adhesion and durability on the battery cell and preventing it from falling off or shifting due to vibration or friction during subsequent handling, assembly, or storage. This device has a high degree of automation and can effectively treat areas on the battery cell prone to rust, providing excellent rust prevention and significantly improving the product's appearance quality.

The rotating member 115 is configured to drive the first driving member 114 to rotate around a first direction, wherein the first direction is the direction in which the first driving member 114 and the second driving member 116 move closer to or further away from each other.

[0091] The first direction in this embodiment is as follows: Figure 4 The X-axis direction in the diagram.

[0092] In this embodiment, the rotating component 115 can be a stepper motor, a servo motor, etc., and is not limited here.

[0093] In this embodiment, both the first support arm 112 and the second support arm 113 can be fixed to the upper side of the movable base 111 by snap-fit ​​or bolt connection. The first drive member 114 and the corresponding first support arm 112 can be connected by a bearing seat, and the second drive member 116 and the corresponding second support arm 113 can also be connected by a bearing seat. The housing on the rotating member 115 is fixed to the first support arm 112, and the rotating shaft on the rotating member 115 is connected to the corresponding first drive member 114 through a bearing seat. It should be noted that the connection structure between the above components is only an example and is not limited here.

[0094] In use, when the first driving member 114 and the second driving member 116 approach each other and clamp the corresponding battery cell, the first driving member 114 is driven to rotate around the X-axis by the rotating member 115. Since the first driving member 114 is rotatably connected to the first support arm 112 and the second driving member 116 is rotatably connected to the second support arm 113, when the rotating member 115 drives the first driving member 114 to rotate around the X-axis, the battery cell located between the first driving member 114 and the second driving member 116 can be rotated synchronously, which facilitates cleaning and spraying different positions of the battery cell.

[0095] According to some embodiments of this application, such as Figure 4 and combined Figure 5 As shown, the clamping assembly 11 also includes a third driving member 117, which is fixed to the side of the movable seat 111 facing the first support arm 112. The third driving member 117 is provided with a clamping seat, which is configured to clamp the bottom surface of the battery cell. The third driving member 117 is configured to drive the clamping seat to rotate around a second direction, wherein the second direction intersects with the first direction.

[0096] The second direction in this embodiment is as follows: Figure 4 The Z-axis direction is defined in the diagram, where the angle between the Z-axis and the X-axis can be 80°, 85°, 90°, etc. For ease of explanation, the following explanation will use the example of the Z-axis and X-axis being perpendicular to each other.

[0097] The third driving component 117 in this embodiment is a rotary servo motor, which is not limited here.

[0098] In this embodiment, the clamping seat is an overall concave housing, with rubber pads connected to the sidewalls of the concave portion. The clamping seat is bolted to the output shaft of the rotary servo motor. After the battery cell is placed into the corresponding clamping seat, the corresponding battery cell is clamped by the rubber pads.

[0099] It should be noted that the structure of the clamping seat described above is merely an example. Other alternative structures can also be used, such as a U-shaped clamping seat. This application does not impose any special restrictions on the specific structure of the clamping seat, as long as the above structure can achieve the purpose of this application.

[0100] In use, when the first drive member 114 and the second drive member 116 approach each other to clamp the corresponding battery cell, when it is necessary to rotate the battery cell around the Z-axis, the first drive member 114 and the second drive member 116 are controlled to move away from each other so that the bottom surface of the battery cell falls onto the corresponding clamping seat. At this time, the clamping seat clamps the bottom part of the battery cell. Subsequently, the third drive member 117 drives the clamping seat to rotate around the Z-axis, thereby synchronously driving the battery cell to rotate around the Z-axis.

[0101] According to some embodiments of this application, such as Figure 4 and combined Figure 5 As shown, the clamping assembly 11 also includes a fourth drive member 118, which is disposed on the side of the movable seat 111 facing the first support arm 112. The fourth drive member 118 is configured to fix the battery cell on the side of a third direction, wherein the third direction is perpendicular to the plane formed by the first direction and the second direction.

[0102] In this embodiment, the third direction is as follows: Figure 4 The Y-axis direction is perpendicular to the plane formed by the X-axis and Z-axis.

[0103] In this embodiment, the fourth driving component 118 can be a clamping cylinder or the like, and is not limited here.

[0104] In this embodiment, the fourth driving member 118 can be fixed to the upper side of the movable base 111 by bolts or snap-fit. After the fourth driving member 118 is fixed, it can be used to conveniently fix the side of the battery cell in the Y-axis direction to prevent the battery cell from moving in the Y-axis direction during subsequent cleaning.

[0105] According to some embodiments of this application, such as Figure 5 As shown, the clamping assembly 11 also includes a movable stage 119, which is connected to the side of the movable base 111 facing the first support arm 112. The fourth drive member 118 is fixed to the side of the movable stage 119 away from the movable base 111. The movable stage 119 is configured to drive the fourth drive member 118 to move in the second direction and the third direction.

[0106] The second and third directions in this embodiment can be referred to the description above, and will not be repeated here.

[0107] In this embodiment, the mobile platform 119 may include a cylinder and a hydraulic lifting frame. The cylinder may be connected to the upper side of the mobile base 111, and the telescopic end of the cylinder may move along the Y-axis. The hydraulic lifting frame may be connected to the corresponding telescopic end and may extend and retract along the Z-axis. The fourth drive component 118 may be connected to the corresponding hydraulic lifting frame.

[0108] It should be noted that the structure of the mobile station 119 described above is merely an example. Other alternative structures can also be used, such as the mobile station 119 including a linear module that can move along the Y-axis. This application does not impose any special restrictions on the specific structure of the mobile station 119, as long as the above structure can achieve the purpose of this application.

[0109] In use, the fourth drive unit 118 can be easily moved in the Y-axis and Z-axis directions by the moving stage 119, so that the fourth drive unit 118 can be adjusted in the Y-axis and Z-axis directions, which is beneficial to the fixation of the battery cell.

[0110] According to some embodiments of this application, such as Figure 5 As shown, the clamping assembly 11 also includes a first detection element 110, which is connected to the moving stage 119 and is configured to detect the energy of the laser when the battery cell is cleaned using a laser.

[0111] In this embodiment, the first detection element 110 can be bolted to the corresponding moving stage 119. The first detection element 110 can be a laser energy meter, a laser power meter, etc., which is not limited here.

[0112] During use, the first detection element 110 facilitates the detection of the laser energy when using laser cleaning of the battery cell, thus avoiding excessive energy from damaging the surface of the battery cell.

[0113] According to some embodiments of this application, such as Figure 6 and combined Figure 3 As shown, the cleaning assembly 12 includes a first bracket 121 and a laser generator 122, wherein the first bracket 121 is fixed to the base 10, and the laser generator 122 is connected to the first bracket 121.

[0114] In this embodiment, the first bracket 121 can be fixed to the base 10 with bolts, and the laser generator 122 can also be fixed to the first bracket 121 with bolts. This is not a limitation.

[0115] In use, when the conveying component 15 moves the battery cell clamped on the moving seat 111 to below the laser generator 122, the conveying component 15 stops moving. At this time, the corresponding battery cell can be rotated around the X-axis by the rotating component 115, or the corresponding battery cell can be rotated around the Z-axis by the third driving component 117. After the battery cell position is adjusted, the battery cell can be quickly cleaned by the laser emitted by the laser generator 122.

[0116] According to some embodiments of this application, such as Figure 6 As shown, the cleaning assembly 12 also includes a fifth drive member 123, which is connected to the first bracket 121 and connected to the laser generator 122. The fifth drive member 123 is configured to drive the laser generator 122 to move in the second direction.

[0117] The second direction in this embodiment can be referred to the description above, and will not be repeated here.

[0118] In this embodiment, the fifth driving component 123 can be a linear module, an electric telescopic rod, etc. The specific type can be determined according to the actual situation, and this specification does not limit it in this embodiment.

[0119] During use, the fifth driving component 123 drives the laser generator 122 to move in the Z-axis direction in order to adjust the position of the laser generator 122 and the battery cell, which is beneficial for cleaning the surface of the battery cell.

[0120] According to some embodiments of this application, such as Figure 6 As shown, the cleaning assembly 12 also includes an optical path control component 124, which is connected to the first bracket 121. The optical path control component 124 is adapted to the laser generator 122 and is configured to deflect and scan the emission path of the laser.

[0121] In this embodiment, the optical path control component 124 can be a galvanometer, which is not limited here.

[0122] In use, the optical path control component 124 deflects and scans the emitted laser beam, allowing it to scan the cell surface along arbitrary trajectories such as straight lines, reciprocating motion, dot matrix, and planar patterns. This transforms the single laser beam emitted by the laser generator 122 into a planar cleaning spot, replacing the traditional mechanical moving platform and significantly improving laser cleaning efficiency. Simultaneously, since the areas on the cell surface requiring cleaning are often precisely targeted regions, the optical path control component 124 can precisely deflect the laser beam to ensure it only targets these areas, avoiding sensitive parts of the cell and preventing thermal damage or physical scratches to non-cleaned areas, thus preserving the cell's electrochemical and sealing performance. Furthermore, the high-speed, uniform scanning of the optical path control component 124 ensures a uniform energy distribution of the laser beam across the cell cleaning area, preventing excessively high local energy from prolonged single-point irradiation and avoiding problems such as melting, deformation, or burn-through of the cell surface substrate.

[0123] According to some embodiments of this application, such as Figure 6 As shown, the cleaning assembly 12 also includes a galvanometer airflow protection component 126, which is connected to the laser generator 122 and is configured to form an airflow protection barrier on the optical path control component 124.

[0124] In this embodiment, the galvanometer airflow protection component 126 can be a galvanometer-matched air knife assembly. The galvanometer-matched air knife assembly includes an air knife body, an air path connecting pipe, and a high-pressure air pump. The air knife body has a ring structure and is fitted onto the laser emission end of the optical path control component 124. The high-pressure air pump provides high-pressure airflow to the air knife body through the air path connecting pipe, forming a ring-shaped airflow protection barrier.

[0125] During use, laser cleaning generates dust, rust, paint chips, and molten residue. These impurities can easily splash onto the lens surface of the optical path control component 124, causing scratches and contamination of the lens, leading to optical path deviation and laser energy attenuation. The galvanometer airflow protection component 126 continuously sprays high-pressure airflow to form an airflow protection barrier in front of the lens of the optical path control component 124, isolating cleaning debris from the lens and preventing impurities from adhering. At the same time, it prevents damage to the internal components of the optical path control component 124 from reverse laser reflection during the cleaning process.

[0126] At the same time, the high-pressure airflow acts synchronously with the laser beam on the surface of the battery cell to be cleaned, which can immediately blow away the dirt and debris stripped by the laser, and prevent the debris from being heated and melted onto the surface of the battery cell by the laser, thus improving the cleanliness. Moreover, during laser cleaning, the battery cell will generate high temperature in some areas due to laser irradiation. The airflow of the galvanometer airflow protection component 126 can simultaneously cool down the battery cell processing area, preventing the battery cell from deforming due to high temperature.

[0127] According to some embodiments of this application, such as Figure 6 and combined Figure 1 or Figure 2 As shown, the rust prevention device also includes a dust collector 25, and the cleaning assembly 12 also includes a first dust suction pipe 125, wherein the first dust suction pipe 125 is fixed to the first bracket 121 and is connected to the dust collector 25.

[0128] In this embodiment, the dust collector 25 can be a vacuum cleaner, and there is no limitation here.

[0129] In this embodiment, the first suction pipe 125 can be connected to the corresponding first bracket 121 by a clip. The first suction pipe 125 can be a corrugated pipe, and the length of the corrugated pipe can be adjusted so that the first suction pipe 125 can be connected to the dust collector 25.

[0130] When the laser generator 122 cleans the welding parts of the battery cell, the dust collector 25 is turned on at the same time. The dust, rust, paint chips and other debris generated during the cleaning process are adsorbed through the first dust suction pipe 125 to prevent the debris generated during the cleaning process from falling onto the welding parts of the battery cell.

[0131] According to some embodiments of this application, such as Figure 6 As shown, the rust prevention device also includes a second detection element 127, which is connected to the first bracket 121 and is configured to detect the wind speed in the first dust extraction duct 125.

[0132] In this embodiment, the second detection element 127 can be an anemometer, which is bolted to the first bracket 121.

[0133] During use, the corresponding wind speed is detected by the second detection element 127 to prevent the dust collector 25 from being unable to remove the impurities after cleaning due to insufficient wind speed during use.

[0134] According to some embodiments of this application, such as Figure 7 and combined Figure 8 As shown, the spraying assembly 13 includes a second bracket 131, a nozzle 132, and a material box. The second bracket 131 is fixed to the base 10, and the nozzle 132 and the material box are both connected to the second bracket 131.

[0135] In this embodiment, the second bracket 131 can be fixed to the base 10 with bolts, and the nozzle 132 and the material box can both be connected to the second bracket 131 with bolts.

[0136] In this embodiment, the material box stores rust-preventive liquid, which can be YJ140-6162CY insulating ink. Compared with other materials, this ink has the following advantages: low viscosity, which allows for smooth spraying onto the battery cell; low diffusion, high accuracy, which can accurately spray the areas that need to be sprayed without masking the areas that do not need to be sprayed; high material utilization; low environmental pressure; and low process cost.

[0137] During use, the anti-rust liquid in the material box can be easily delivered to the spray nozzle 132 by the negative pressure pump so as to spray the welded parts on the battery cell.

[0138] According to some embodiments of this application, such as Figure 7 and combined Figure 8 As shown, the spraying assembly 13 also includes a sixth drive member 133 and a seventh drive member 134, wherein the sixth drive member 133 is connected to the second bracket 131, the seventh drive member 134 is connected to the sixth drive member 133, and the seventh drive member 134 is connected to the nozzle 132; the sixth drive member 133 is configured to drive the seventh drive member 134 to move in a first direction, and the seventh drive member 134 is configured to drive the nozzle 132 to move in a second direction.

[0139] The first and second directions in this embodiment can be referred to the description above, and will not be repeated here.

[0140] In this embodiment, the sixth driving component 133 and the seventh driving component 134 can both be linear modules, cylinders, electric telescopic rods, etc. The specific type can be determined according to the actual situation, and this specification does not limit this embodiment.

[0141] In use, the sixth driving component 133 drives the seventh driving component 134 to move in the X-axis direction, and the seventh driving component 134 drives the nozzle 132 to move in the Z-axis direction. This allows the position of the nozzle 132 in the X-axis and Z-axis directions to be adjusted, which facilitates the alignment of the nozzle 132 with the welding part of the battery cell and improves the spraying effect.

[0142] According to some embodiments of this application, such as Figure 7 and combined Figure 8 As shown, the spraying assembly 13 also includes a first curing component 135, which is disposed on the seventh drive component 134 and is configured to pre-cure the anti-rust liquid sprayed on the battery cell.

[0143] In this embodiment, the first curing component 135 can be fixed to the seventh driving component 134 by bolts. The first curing component 135 can be a UV lamp, which is not limited here.

[0144] When in use, after the rust inhibitor is sprayed onto the welding part of the battery cell, the rust inhibitor is pre-cured by the ultraviolet light emitted by the first curing component 135, which can prevent the rust inhibitor from shifting due to inertia during the movement of the battery cell.

[0145] According to some embodiments of this application, such as Figure 7 and combined Figure 8 As shown, the spraying assembly 13 also includes a sensor 136, which is disposed on the seventh drive member 134, and the position of the sensor 136 is adapted to the position of the spray head 132.

[0146] In this embodiment, sensor 136 can be a collision avoidance sensor or a distance sensor, for reference. Figure 8 As shown, both the sensor 136 and the nozzle 132 are located at the lower end of the seventh drive unit 134.

[0147] During use, the sensor 136 can easily sense the position of the battery cell, preventing the nozzle 132 from colliding with the battery cell.

[0148] According to some embodiments of this application, such as Figure 7 and combined Figure 8 As shown, the spraying assembly 13 also includes a third detection element 137, which is connected between the nozzle 132 and the negative pressure pump. The third detection element 137 is configured to detect the pressure of the rust inhibitor delivered to the nozzle 132.

[0149] In this embodiment, the third detection element 137 is a pressure sensor.

[0150] During use, the pressure of the rust inhibitor delivered to the nozzle 132 is detected by a pressure sensor to prevent the rust inhibitor sprayed from the nozzle 132 from being too low.

[0151] According to some embodiments of this application, such as Figure 7 and combined Figure 8 As shown, the spraying assembly 13 also includes a fourth detection element 138, which is connected to the second bracket 131 and is configured to detect airborne particulate matter.

[0152] In this embodiment, the fourth detection element 138 can be fixed to the second bracket 131 by bolts. The fourth detection element 138 can be a PM2.5 sensor, which is not limited here.

[0153] During use, the fourth detection component 138 is used to detect airborne particulate matter in the spraying area to prevent the internal environment from failing to meet the purity standards during spraying.

[0154] According to some embodiments of this application, such as Figure 7 and combined Figure 8As shown, the spraying assembly 13 also includes a first temperature controller 139 and a heating element, the heating element being configured to heat the rust inhibitor in the material box, and the first temperature controller 139 being configured to detect the temperature of the rust inhibitor in the material box.

[0155] The heating element in this embodiment can be an electric heating wire, a heating plate, etc., and is not limited here.

[0156] In this embodiment, the first temperature controller 139 can be fixed to the second bracket 131 by bolts, and the heating element can be fixed to the surface of the material box by bolts.

[0157] During use, the rust inhibitor in the material box is heated by the heating element, and the temperature of the rust inhibitor in the material box is detected by the first temperature controller 139 to avoid the rust inhibitor being too cold during use, which would affect the spraying effect.

[0158] According to some embodiments of this application, such as Figure 9 As shown, the curing assembly 14 includes a third bracket 141 and a second curing component 142, wherein the third bracket 141 is fixed to the base 10, the second curing component 142 is connected to the third bracket 141, and the second curing component 142 is configured to cure the anti-rust liquid sprayed on the battery cell.

[0159] In this embodiment, the third bracket 141 can be fixed to the base 10 with bolts.

[0160] In this embodiment, the second curing component 142 can be a UV lamp or an ultraviolet lamp, and there is no limitation here.

[0161] When in use, after the anti-rust liquid is sprayed onto the welding parts of the battery cell, the anti-rust liquid is cured by the ultraviolet light emitted by the second curing component 142 after the battery cell is transported to the second curing component 142, thereby improving the adhesion and durability of the anti-rust liquid and preventing the anti-rust liquid from falling off or shifting due to vibration or friction during subsequent handling, assembly or storage.

[0162] According to some embodiments of this application, such as Figure 9 As shown, the curing assembly 14 also includes an eighth drive member 143, which is connected to the third bracket 141 and connected to the second curing component 142. The eighth drive member 143 is configured to drive the second curing component 142 to move in the second direction.

[0163] In this embodiment, the eighth driving component 143 can be a linear module, an electric telescopic rod, etc., and is not limited here.

[0164] In this embodiment, the eighth driving member 143 is bolted to the third bracket 141, and the second curing member 142 can also be bolted to the eighth driving member 143, which is not limited here.

[0165] In use, the second curing component 142 is moved in the Z-axis direction by the eighth driving component 143, which makes it easy to adjust the relationship between the second curing component 142 and the battery cell, thereby facilitating the curing of the rust inhibitor.

[0166] According to some embodiments of this application, such as Figure 9 As shown, the curing assembly 14 also includes a fifth detection element 144, which is connected to the second curing component 142 and is configured to detect the airflow velocity.

[0167] In this embodiment, the fifth detection component 144 can be a wind speed detector, which is not limited here.

[0168] During use, the airflow speed in the corresponding area is detected by the fifth detection element 144 to ensure that the heat generated by the second curing component 142 during operation can be carried away in a timely and uniform manner, avoiding local overheating that could damage the second curing component 142.

[0169] According to some embodiments of this application, such as Figure 9 As shown, the curing assembly 14 also includes a sixth detection element 145, which is connected to the third bracket 141 and is configured to detect air temperature.

[0170] In this embodiment, the sixth detection element 145 can be a temperature sensor, which is not limited here.

[0171] During use, the temperature data of the corresponding area is detected by the sixth detection element 145 to avoid the deformation of the cell surface material due to excessive temperature, while excessive temperature will reduce the curing rate.

[0172] According to some embodiments of this application, such as Figure 9 As shown, the curing assembly 14 also includes a seventh detection element 146, which is connected to the third bracket 141 and is configured to detect airborne particulate matter.

[0173] In this embodiment, the seventh detection element 146 can be fixed to the third bracket 141 by bolts. The seventh detection element 146 can be a PM2.5 sensor, which is not limited here.

[0174] During use, airborne particulate matter is detected by the seventh detection component 146 to prevent the internal environment from failing to meet purity standards during spraying.

[0175] According to some embodiments of this application, such as Figure 9 As shown, the curing assembly 14 also includes a second temperature controller 147, which is connected to the third bracket 141 and is configured to detect the temperature of the cell surface.

[0176] In this embodiment, the second temperature controller 147 can be fixed to the third bracket 141 with bolts. The second temperature controller 147 detects the temperature of the battery cell surface to prevent the surface temperature of the battery cell from becoming too high when the ultraviolet light emitted by the second curing component 142 cures the anti-rust liquid.

[0177] According to some embodiments of this application, such as Figure 9 and combined Figure 1 or Figure 2 As shown, the rust prevention device also includes a dust collector 25, and the curing component 14 also includes a second dust suction pipe 148, which is fixed to the third bracket 141 and connected to the dust collector 25.

[0178] In this embodiment, the dust collector 25 can be a vacuum cleaner, and there is no limitation here.

[0179] In this embodiment, the second suction pipe 148 can be connected to the corresponding third bracket 141 by a clip. The second suction pipe 148 can be a corrugated pipe, and the length of the corrugated pipe can be adjusted so that the second suction pipe 148 can be connected to the dust collector 25.

[0180] When in use, when the second curing component 142 cures the anti-rust liquid on the welding part of the battery cell, the dust collector 25 is turned on at the same time. The dust particles in the curing area are adsorbed through the second dust suction pipe 148 to prevent dust particles from falling onto the anti-rust liquid and affecting the anti-rust effect.

[0181] According to some embodiments of this application, such as Figure 1 and combined Figure 3 As shown, the rust prevention device also includes a cover 19 connected to the base 10, wherein the cleaning component 12, the spraying component 13, the curing component 14 and the conveying component 15 are all located in the inner cavity enclosed by the cover 19 and the base 10.

[0182] In this embodiment, the cover 19 can be bolted to the upper surface of the base 10. At this time, the cleaning component 12, the spraying component 13, the curing component 14 and the conveying component 15 are located in the inner cavity enclosed by the cover 19 and the base 10.

[0183] In this way, the cooperation between the cover 19 and the base 10 can prevent external debris from affecting the cleanliness of the working areas of the cleaning component 12, the spraying component 13, and the curing component 14.

[0184] According to some embodiments of this application, such as Figure 3As shown, the rust prevention device also includes a first isolation component 16, a second isolation component 17, and a third isolation component 18. The first isolation component 16, the second isolation component 17, and the third isolation component 18 are all disposed on the base 10, and the first isolation component 16, the second isolation component 17, and the third isolation component 18 can all be closed or opened in a first direction. The first isolation component 16 is disposed between the clamping component 11 and the cleaning component 12, the second isolation component 17 is disposed between the cleaning component 12 and the spraying component 13, and the third isolation component 18 is disposed between the spraying component 13 and the curing component 14.

[0185] In this embodiment, the first isolation component 16, the second isolation component 17, and the third isolation component 18 can all be automatic closing doors, and no limitation is made here.

[0186] After the clamping component 11 clamps the corresponding battery cell, the first isolation component 16 opens, and the conveying component 15 conveys the clamping component 11 to the cleaning component 12. At this time, the first isolation component 16 and the second isolation component 17 close, and the cleaning component 12 cleans the battery cell.

[0187] After cleaning is completed, the second isolation component 17 is opened, and the conveying component 15 conveys the clamping component 11 to the spraying component 13. At this time, the second isolation component 17 and the third isolation component 18 are closed, and the spraying component 13 sprays the battery cell.

[0188] After the spraying is completed, the third isolation component 18 is opened, and the conveying component 15 conveys the clamping component 11 to the curing component 14. Then the third isolation component 18 is closed, and the curing component 14 cures the anti-rust liquid at the welding part of the battery cell.

[0189] In this embodiment, since the cleaning component 12 generates dust, debris, and metal oxide slag during laser cleaning, and is accompanied by airflow disturbance from the high-pressure airflow, the dust / debris can be prevented from drifting to the spraying / curing station by the cooperation of the first isolation component 16 and the second isolation component 17.

[0190] Since the spraying component 13 requires a dust-free and quiet environment during spraying, and will generate atomized paint mist and glue mist, the second isolation component 17 and the third isolation component 18 can work together to prevent the paint mist from spreading to the cleaning station and adhering to the laser galvanometer and lens, causing light path obstruction / energy attenuation. It can also prevent the paint mist from entering the uncured area of ​​the curing station, resulting in coating sagging and uneven curing.

[0191] Since the curing component 14 requires a sealed environment free from stray light interference during curing (UV curing requires high utilization of ultraviolet light), and the ultraviolet light emitted by the UV lamp will produce a slight ozone, isolation can prevent the ultraviolet light in the curing area from directly shining on other workstations and causing equipment components to age. At the same time, it can prevent ozone from spreading to the operating area, and also ensure the temperature / light stability of the curing area, thereby improving the curing uniformity of the rust inhibitor.

[0192] According to some embodiments of this application, such as Figure 1 and combined Figure 2 As shown, the rust prevention device also includes a safety protection component 24, which is disposed on the base 10 and is adapted to the clamping assembly 11. The safety protection component 24 is configured to detect whether an external object enters the working area of ​​the clamping assembly 11.

[0193] In this embodiment, the safety protection component 24 can be a safety light curtain. The safety light curtain detects whether an external object enters the working area of ​​the clamping assembly 11. When an external object is detected entering the working area of ​​the clamping assembly 11, the device is triggered to stop to avoid accidents.

[0194] According to some embodiments of this application, such as Figure 1 As shown, the cover 19 is provided with at least one switch door 20, and the switch door 20 is provided with an observation port 21.

[0195] In this embodiment, one or two opening and closing doors 20 can be provided on the cover 19, and each opening and closing door 20 is provided with an observation port 21.

[0196] In this embodiment, the cover 19 is provided with three switch doors 20, and the positions of the three switch doors 20 correspond to the cleaning component 12, the spraying component 13, and the curing component 14, respectively.

[0197] The cover 19 can be easily opened by the switch door 20, allowing for maintenance in case of malfunctions at the cleaning component 12 station, the spraying component 13 station, and the curing component 14 station. At the same time, the working status of each station can be easily observed through the observation port 21.

[0198] According to some embodiments of this application, the rust prevention device further includes a processor 22 and a status indicator 23, both of which are mounted on the cover 19. The processor 22 is electrically connected to electrical components on the clamping assembly 11, the cleaning assembly 12, the spraying assembly 13, the curing assembly 14, and the conveying assembly 15, respectively. Under different conditions of the electrical components, the processor 22 is configured to control the status indicator 23 to display different colors.

[0199] In this embodiment, the status indicator component 23 can be a three-color light, which corresponds to green, yellow and red. Green corresponds to the overall device being in operation, yellow corresponds to the overall device being in standby mode, and red corresponds to the overall device being in fault mode.

[0200] When in use, the processor 22 controls the status indicator 23 in green when the electrical components are in operation; in yellow when the electrical components are in standby mode; and in red when the electrical components are in a fault state. This makes it easier for staff to quickly inspect and judge the overall operating condition of the device.

[0201] It is understandable that the aforementioned status indicator component 23 may also display other colors to correspond to different operating states, and this is not limited here.

[0202] In summary, when using this device, the battery cell is first placed onto the corresponding clamping assembly 11, where the first drive member 114 and the second drive member 116 on the clamping assembly 11 interact to clamp the battery cell. At this time, the first isolation assembly 16 opens, and then the clamping assembly 11 is moved along the Y-axis to the cleaning assembly 12 via the conveying assembly 15.

[0203] After the clamping assembly 11, along with the corresponding battery cell, moves to the cleaning assembly 12, the conveying assembly 15 stops moving. At this time, the first isolation assembly 16 and the second isolation assembly 17 close. Simultaneously, the rotating component 115 and the third driving component 117 on the clamping assembly 11 cooperate to flip the battery cell to a preset position. Then, the fifth driving component 123 drives the laser generator 122 to move along the Z-axis. After the laser generator 122 is aligned with the battery cell, the fifth driving component 123 stops moving. At this point, the laser emitted by the laser generator 122 can be used to clean the welded parts of the battery cell. The welding slag generated during cleaning can be sucked into the dust collector 25 through the first dust suction pipe 125.

[0204] After cleaning, the second isolation component 17 opens, and the conveying component 15 drives the clamping component 11 to continue moving along the Y-axis to the spraying component 13. After the clamping component 11, along with the corresponding battery cell, moves to the spraying component 13, the conveying component 15 stops moving, and at this time, the second isolation component 17 and the third isolation component 18 close. Subsequently, the interaction between the sixth drive component 133 and the seventh drive component 134 is used to adjust the position of the nozzle 132 on the X and Z axes. Once the position of the nozzle 132 is adjusted, spraying begins on the welding parts of the battery cell. At the same time, the first curing component 135 is used to pre-cure the sprayed rust inhibitor.

[0205] After spraying, the third isolation component 18 opens, and the conveying component 15 drives the clamping component 11 to continue moving along the Y-axis to the curing component 14. After the clamping component 11, along with the corresponding battery cell, moves to the curing component 14, the conveying component 15 stops moving, and the third isolation component 18 closes. Then, the eighth drive component 143 adjusts the position of the second curing component 142 in the Z-axis direction. Once the position of the second curing component 142 is adjusted, the rust inhibitor begins to cure. After curing, all components return to their initial positions. This device has a high degree of automation and can effectively treat areas on the battery cell prone to rust, providing excellent rust prevention and significantly improving the product's appearance quality.
