Description

Technical Field

[0001] This application belongs to the field of battery technology, and in particular relates to a dust removal device and a laser cleaning system. Background Technology

[0002] Laser cleaning processes generate a large amount of dust and fumes, so laser cleaning systems are generally equipped with dust removal devices. However, current dust removal devices have poor dust removal efficiency and need to be improved. Utility Model Content

[0003] In view of the above problems, this application provides a dust removal device and a laser cleaning system, which aim to improve dust removal efficiency.

[0004] In a first aspect, embodiments of this application provide a dust removal device, including a hood, a conveying pipe, and a power enhancement mechanism; the hood is provided with a suction channel and a partition, the suction channel being divided by the partition into a first channel and a second channel arranged in an alternating manner; both the first channel and the second channel have an air inlet and an air outlet; the conveying pipe is connected to the first channel or the second channel through the air outlet; the power enhancement mechanism is correspondingly arranged with the conveying pipe, and the power enhancement mechanism is used to enhance the gas flow power in the conveying pipe.

[0005] The dust removal device provided in this application embodiment has a first channel and a second channel separated by a partition. The first channel and the second channel are respectively connected to the conveying pipe through an air outlet. The conveying pipe is equipped with a power enhancement mechanism to enhance the adsorption force and air volume. In this way, when the dust is being collected, the gas is less likely to generate eddies after entering the first channel or the second channel, and can cover the entire processing area (multiple edges of the electrode). At the same time, the setting of the power enhancement mechanism can enable the dust generated during processing to be transported to the designated area by the dust removal device as quickly and as much as possible, which helps to improve the dust removal efficiency.

[0006] In some possible implementations of the first aspect, the power enhancement mechanism includes an ejector mechanism for increasing the gas pressure within the delivery pipe by introducing an auxiliary power flow.

[0007] The power enhancement mechanism adopts an ejector mechanism, which has a simple structure, high reliability, and long service life.

[0008] In some possible implementations of the first aspect, the ejector mechanism includes a pneumatic conveyor.

[0009] The ejector mechanism uses a pneumatic conveyor, which has the advantages of low cost, easy installation, no consumables, easy maintenance, flexibility, convenience, and easy automation control.

[0010] In some possible implementations of the first aspect, the power enhancement mechanism and / or delivery pipe are equipped with a throttle valve.

[0011] The throttle valve allows for separate adjustment of the flow rate in different delivery pipes, thereby ensuring that the suction force of each delivery pipe is relatively uniform, and thus making the dust removal effect of the processing areas corresponding to different channels comparable.

[0012] In some possible implementations of the first aspect, a wind speed detection module is provided on the delivery pipe.

[0013] The wind speed detection module allows users to monitor the wind speed in each delivery pipe and adjust the throttle valves based on the monitoring results, ensuring that the air volume in different delivery pipes is comparable, thus achieving comparable dust removal effects in different channels.

[0014] In some possible implementations of the first aspect, the wind speed detection module is located on the air outlet side of the power enhancement mechanism and is spaced apart from the power enhancement mechanism.

[0015] The staggered arrangement of the wind speed detection module and the power enhancement mechanism allows sufficient time and space for the airflow discharged from the power enhancement mechanism to self-adjust and mix, resulting in a more uniform and stable velocity profile (the distribution of flow velocity across the cross-section of the delivery pipe). The wind speed measured by the detection module during this stable phase provides a temporally stable and spatially representative average wind speed, ensuring reliable data and accurate feedback. Furthermore, the higher pressure and velocity of the airflow discharged from the power enhancement mechanism's outlet are mitigated by the aforementioned arrangement, reducing the continuous physical impact and pressure load on the wind speed detection module. This improves the module's durability, reliability, and measurement accuracy, while reducing maintenance frequency and costs.

[0016] In some possible implementations of the first aspect, the delivery pipe includes a hose disposed between the power enhancement mechanism and the wind speed detection module.

[0017] Power enhancement mechanisms typically generate significant mechanical vibrations and airflow pulsations during operation. Flexible hoses, with their excellent damping and flexibility, can effectively absorb and isolate these mechanical vibrations and airflow pulsations. This reduces the risk of the wind speed detection module being impacted by these vibrations or pulsations, lowering the risk of damage to the module. Furthermore, they can smooth out airflow pulsations to some extent, resulting in more stable airflow reaching the wind speed detection module.

[0018] In some possible implementations of the first aspect, four conveying pipes are provided, arranged around the cover, and each of the four conveying pipes is connected to a different channel. The different channels include a first channel and a second channel.

[0019] This allows the placement of the delivery pipe to be unrestricted by the size of the space enclosed by the enclosure, and also facilitates the installation of the delivery pipe.

[0020] In some possible implementations of the first aspect, the delivery pipe is located in the middle of the length direction of the corresponding channel, which is either a first channel or a second channel connected to the delivery pipe.

[0021] In this embodiment, the conveying pipe is centrally located, which helps to discharge dust located in different areas of the first or second channel, thus improving the dust removal effect.

[0022] In some possible implementations of the first aspect, the dust removal device also includes a fixing element disposed on the cover.

[0023] The fasteners facilitate the fixing and installation of the cover.

[0024] In some possible implementations of the first aspect, the first channel and / or the second channel are provided with a fixing element.

[0025] Both the first and second channels have two sections, which allows the same cover to be fixed by different fasteners. This helps to ensure a stable connection between the cover and other components, and also reduces the number of fasteners and the number of parts in the dust removal device.

[0026] In some possible implementations of the first aspect, the first channel and the second channel extend along a straight line, and the length of the first channel is greater than the length of the second channel.

[0027] Since electrodes are generally rectangular in structure, they have long and short sides. Using the solution provided in this embodiment, the first channel corresponds to the long side of the electrode and is used to absorb dust generated during the cleaning of that side. The second channel corresponds to the short side of the electrode and is used to absorb dust generated during the cleaning of that side. This allows the cover to cover the entire cleaning area of ​​the electrode while keeping the cover's size relatively small, achieving multiple benefits.

[0028] In some possible implementations of the first aspect, the partition is set at an acute angle to the length direction of the first channel, and the partition is set at an acute angle to the length direction of the second channel.

[0029] By adopting the solution provided in this embodiment, dust flowing to the area where the partition is located is less likely to get stuck between the angle formed by the partition and the side wall of the cover, which helps to discharge the dust.

[0030] In some possible implementations of the first aspect, the cover is a one-piece molded structure.

[0031] The cover adopts a one-piece molded structure, which is structurally stable and easy to manufacture.

[0032] Secondly, a laser cleaning system is provided for cleaning electrodes. The laser cleaning system includes a laser cleaning device and a dust removal device provided by any of the above solutions. The dust removal device is located on the side of the laser cleaning device close to the electrodes.

[0033] The effect of the second aspect is the same as that of the first aspect, so it will not be repeated here.

[0034] In some possible implementations of the second aspect, the dust removal device is connected to the laser cleaning device.

[0035] The solution provided in this embodiment can realize the linkage between the dust removal device and the laser cleaning device. Compared with the dust removal device and the laser cleaning device being controlled by drive mechanisms to move separately, the number of drive mechanisms can be saved, the number of mechanisms in the laser cleaning system can be reduced, and its manufacturing cost can be reduced.

[0036] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0054] During the battery manufacturing stage, electrode cleaning plays a crucial role in the quality, performance, and stability of the battery. To address the industry's safety concerns, laser cleaning is performed on battery electrodes during the marking process. This technology uses a high-energy laser beam to irradiate the electrode surface, causing the conductive dust generated and adhering to the electrode surface during production to evaporate or peel off instantly, completely eliminating the risk of explosion and short circuit.

[0055] Laser cleaning processes generate a large amount of dust and fumes, so laser cleaning systems are generally equipped with dust removal devices. However, current dust removal devices have poor dust removal efficiency and need to be improved.

[0056] To address the aforementioned issues, this application provides a dust removal device. In this device, a first channel and a second channel are separated by a partition, and both channels are connected to a conveying pipe via air outlets. The conveying pipe is equipped with a power enhancement mechanism to increase adsorption force and airflow. This design prevents the formation of eddies when the gas enters the first or second channel during dust collection, and ensures coverage of the entire processing area (multiple edges of the electrode). Furthermore, the power enhancement mechanism allows the dust generated during processing to be transported to the designated area by the dust removal device as quickly and extensively as possible, thus improving dust removal efficiency.

[0057] The dust removal device disclosed in this application can be used in laser cleaning systems, electrode processing equipment, or similar processing equipment that use dust removal devices.

[0058] For ease of explanation, the following embodiments use a laser cleaning system as an example.

[0059] Figure 1 This is a schematic diagram of the structure of a laser cleaning system provided in some embodiments of this application.

[0060] like Figure 1 As shown, the laser cleaning system includes at least a laser cleaning device and a dust removal device 100.

[0061] The laser cleaning device generates a beam of a specific wavelength. During laser powder removal, the specific wavelength beam, such as a 1064nm fiber laser, is preferentially absorbed by the dust particles on the surface of the electrode 200. After absorbing energy, the particles instantly vaporize or explode and detach. The substrate material of the electrode 200, due to its high reflectivity to this wavelength of laser, absorbs only a small amount of energy, thus avoiding thermal deformation or chemical changes. By controlling the laser power density between the "dust removal threshold" and the "substrate damage threshold," an energy safety window is formed—for example, for the aluminum foil substrate of the lithium electrode 200, the power density is typically controlled at 5-15W / mm², which can thoroughly remove micron-sized active material powder without damaging the coating structure on the surface of the electrode 200.

[0062] In addition, the laser cleaning system may also include an electrode conveying device 300, etc.

[0063] The electrode conveying device 300 may include, but is not limited to, a robotic arm, a roller conveyor, a conveyor belt, etc. The electrode conveying device 300 is used to convey the electrode 200.

[0064] The dust removal device 100 is generally located below the laser cleaning device and is used to absorb and discharge the dust generated during the processing to a designated area (dust collection box, filter device, etc.) during the operation of the laser cleaning device.

[0065] Figure 2This is a schematic diagram of the structure of a dust removal device provided in some embodiments of this application; Figure 3 This is a structural schematic diagram of the cross-section of a dust removal device provided in some embodiments of this application.

[0066] Please refer to Figures 1 to 3 This application provides a dust removal device 100. The dust removal device 100 includes a cover 10, a conveying pipe 20, and a power enhancement mechanism 30.

[0067] The enclosure 10 contains an air intake channel and a partition 10a. The air intake channel is divided by the partition 10a into a first channel 11 and a second channel 12 arranged in an alternating manner. Both the first channel 11 and the second channel 12 have an air inlet 13 and an air outlet. The delivery pipe 20 is connected to the first channel 11 or the second channel 12 through the air outlet. A power enhancement mechanism 30 is correspondingly provided with the delivery pipe 20, and the power enhancement mechanism 30 is used to enhance the gas flow power within the delivery pipe 20.

[0068] The cover 10 is the main part of the dust removal device 100, which consists of one or more components. It can be connected to the laser cleaning device mentioned above or to the electrode conveying device 300, depending on the specific needs of use.

[0069] The suction channel refers to the hollow structure inside the cover 10, which can contain dust and allow the dust to flow within a certain range. In this embodiment, the shape of the suction channel is adapted to the shape of the edge of the electrode 200, and is arranged in a square shape or similar to a square shape.

[0070] There are two first channels 11 and two second channels 12. The staggered arrangement means that the two ends of the two first channels 11 are connected by two second channels 12 respectively, and adjacent first channels 11 and second channels 12 are separated by partitions 10a.

[0071] The first channel 11 and the second channel 12 are respectively set to correspond to one edge of the electrode 200.

[0072] The air inlet 13 is an opening on the outer wall of the cover 10, which is used to allow gas containing dust, liquid, etc. to enter. The air outlet is an opening on the outer wall of the cover 10, which can connect the target channel (first channel 11 or second channel 12) and the delivery pipe 20, so that the gas containing dust, liquid, etc. inside the cover 10 can be discharged and enter the delivery pipe 20.

[0073] The first channel 11 and the second channel 12 are respectively connected to at least one delivery pipe 20.

[0074] The partition 10a is a plate used to separate the first channel 11 and the second channel 12. It can be integrally formed with the cover 10 or separately connected to the cover 10, depending on the application requirements.

[0075] The power enhancement mechanism 30 is located on the conveying pipe 20 and can be an ejector mechanism, a fan, a vacuum pump, etc. It is used to enhance the adsorption force and air volume of the conveying pipe 20 to improve the dust removal efficiency of the dust removal device 100.

[0076] It is understandable that the delivery pipe 20 is generally equipped with a vacuum pump, exhaust fan and other power devices at the end away from the cover 10, and the power enhancement mechanism 30 is only used to enhance the gas flow power inside the delivery pipe 20.

[0077] Description of the usage process of the dust removal device 100 provided in this application embodiment:

[0078] In use, the air inlet 13 is positioned towards the electrode 200. This allows the air inlet 13 to be more closely attached to the processing area (the surface of the electrode 200). When the laser cleaning device is operating, the dust removal device 100 also operates. After dust and other impurities are generated, the gas carrying the dust can enter the first channel 11 or the second channel 12 through the air inlet 13, and then enter the conveying pipe 20 through the air outlet, and then be discharged to the designated area (dust collection box, filter device, etc.) through the conveying pipe 20. During this process, the power enhancement mechanism 30 can increase the air volume in the conveying pipe 20, so that as much dust as possible can enter the first channel 11 or the second channel 12 through the air inlet 13, and then be discharged through the conveying pipe 20. This allows the dust removal device 100 to quickly remove the dust generated during processing, which helps to improve dust removal efficiency and yield.

[0079] The dust removal device 100 provided in this application embodiment has a first channel 11 and a second channel 12 separated by a partition 10a. The first channel 11 and the second channel 12 are respectively connected to the conveying pipe 20 through an air outlet. The conveying pipe 20 is provided with a power enhancement mechanism 30 for enhancing adsorption force and air volume. In this way, when dust is being collected, the gas is less likely to generate eddies after entering the first channel 11 or the second channel 12, and can cover the entire processing area (multiple edges of the electrode 200). The setting of the power enhancement mechanism 30 can enable the dust generated during processing to be transported to the designated area by the dust removal device 100 as quickly and as much as possible, which helps to improve dust removal efficiency and yield.

[0080] In some embodiments, the power enhancement mechanism 30 includes an ejector mechanism for increasing the gas pressure within the delivery pipe 20 by introducing an auxiliary power flow.

[0081] The ejector mechanism can be a Venturi ejector, a steam / air ejector, etc. It does not directly enhance the main airflow, but uses the energy of the high-pressure fluid (driving medium) to create or enhance the negative pressure (vacuum) and airflow required for dust removal.

[0082] The ejector mechanism has no impellers, bearings, pistons or other moving mechanical parts inside. It has a simple structure, is not prone to wear, requires no lubrication, has no mechanical seal leakage problems, is resistant to high temperature and has high reliability.

[0083] Therefore, the power enhancement mechanism 30 adopts an ejector mechanism, which has a simple structure, high reliability, and long service life.

[0084] In some embodiments, the ejector mechanism includes a pneumatic delivery device.

[0085] Pneumatic conveyors, also known as pneumatic amplifiers, air amplifiers, vacuum conveyors, etc., are a type of supplementary equipment for pneumatic conveying systems that is simple in structure, flexible in use, and requires no expensive investment or maintenance.

[0086] The working principle of a pneumatic conveyor is as follows: Powered by compressed air, the high-speed airflow draws air from the inlet side of the conveyor and ejects it towards the outlet side. Internally, it functions like a straight pipe, allowing materials of appropriate size to pass through.

[0087] The ejector mechanism uses a pneumatic conveyor, which has the advantages of low cost, easy installation, no consumables, easy maintenance, flexibility, convenience, and easy automation control.

[0088] In some embodiments, the power enhancement mechanism 30 and / or the delivery pipe 20 are provided with a throttle valve 40.

[0089] A throttle valve 40 is a valve or device that creates throttling resistance to a fluid (gas or liquid) by locally reducing the cross-sectional area of ​​the flow channel. It can precisely regulate and control the flow rate, pressure, or velocity of the fluid. By rotating a handwheel, handle, or using an actuator, the opening area between the valve core and seat can be continuously changed, achieving stepless regulation of flow rate and pressure. Specifically, the throttle valve 40 can be a needle valve, a gate valve (used for regulation), a butterfly valve (partially used for regulation), or an orifice plate (for fixed throttling), etc.

[0090] The power enhancement mechanism 30 and / or the delivery pipe 20 are equipped with throttle valves 40, including the following options: First, the power enhancement mechanism 30 is equipped with throttle valve 40; Second, the delivery pipe 20 is equipped with throttle valve 40; Third, both the power enhancement mechanism 30 and the delivery pipe 20 are equipped with throttle valves 40.

[0091] The throttle valve 40 allows for separate adjustment of the flow rate of different conveying pipes 20, thereby making the suction force of each conveying pipe 20 relatively uniform, and thus making the dust removal effect of the processing areas corresponding to different channels comparable.

[0092] In some embodiments, the delivery pipe 20 is provided with a wind speed detection module 50.

[0093] The wind speed detection module 50 can sense the speed of gas flow (i.e., wind speed) and convert it into a standard electrical signal that can be measured, processed, and transmitted. It is not just a sensor itself, but usually also includes the necessary signal conditioning circuitry to output an analog or digital signal that is easy for microcontrollers (such as Arduino and PLC) to read.

[0094] The wind speed detection module 50 allows users to detect the wind speed in each delivery pipe 20, and adjust each throttle valve 40 according to the detection results so that the air volume in different delivery pipes 20 is equal, thereby making the dust removal effect of different channels equal.

[0095] In some embodiments, the wind speed detection module 50 is located on the air outlet side of the power enhancement mechanism 30 and is spaced apart from the power enhancement mechanism 30.

[0096] The interval setting refers to the existence of a certain distance between the wind speed detection module 50 and the power enhancement mechanism 30.

[0097] The airflow at the outlet of the power enhancement mechanism 30 (such as a fan or ejector) is usually highly turbulent and uneven, with eddies, pulsations, and strong turbulence. If the wind speed detection module 50 is installed close to the outlet of the power enhancement mechanism 30, the measured data will be chaotic and fluctuate greatly in an instant, and cannot represent the true average wind speed.

[0098] The spaced arrangement between the wind speed detection module 50 and the power enhancement mechanism 30 allows sufficient time and space for the airflow discharged from the power enhancement mechanism 30 to self-adjust and mix, resulting in a more uniform and stable velocity profile (the distribution of flow velocity across the cross-section of the delivery pipe 20). The wind speed measured by the wind speed detection module 50 during this stable phase provides a temporally stable and spatially representative average wind speed, ensuring reliable data and accurate feedback. Furthermore, the higher pressure and velocity of the airflow discharged from the power enhancement mechanism 30 reduce the continuous physical impact and pressure load on the wind speed detection module 50, thereby improving its durability, reliability, and measurement accuracy, while reducing maintenance frequency and costs.

[0099] In some embodiments, the delivery pipe 20 includes a hose 21. The hose 21 is disposed between the power enhancement mechanism 30 and the wind speed detection module 50.

[0100] Hose 21 refers to a flexible tube that can be bent, and can be made of rubber, silicone or a flexible tube with a braided layer, etc.

[0101] The power enhancement mechanism 30 typically generates significant mechanical vibration and airflow pulsation during operation. The hose 21 has good damping and flexibility, which can effectively absorb and isolate the aforementioned mechanical vibration and airflow pulsation, thereby reducing the risk of the wind speed detection module 50 being impacted by the aforementioned vibration or pulsation, reducing the risk of damage to the wind speed detection module 50, and can also smooth the airflow pulsation to a certain extent, making the airflow reaching the wind speed detection module 50 more stable.

[0102] In some embodiments, four delivery pipes 20 are provided. The four delivery pipes 20 are arranged around the cover 10. The four delivery pipes 20 are respectively connected to different channels. The different channels include a first channel and a second channel.

[0103] The four conveying pipes 20 are arranged around the cover 10, meaning that all four conveying pipes 20 are located outside the space enclosed by the cover 10, and the four conveying pipes 20 are spaced apart, each corresponding to a different channel. Specifically, one conveying pipe 20 is located outside one of the first channels 11 (i.e., on the side away from the other first channel 11), one conveying pipe 20 is located outside another first channel 11, one conveying pipe 20 is located outside one of the second channels 12, and one conveying pipe 20 is located outside the other second channel 12.

[0104] This allows the placement of the delivery pipe 20 to be unrestricted by the size of the space enclosed by the cover 10, and facilitates the installation of the delivery pipe 20.

[0105] In some embodiments, the delivery pipe 20 is located at the middle of the length direction of the corresponding channel. The corresponding channel is either a first channel 11 or a second channel 12 that communicates with the delivery pipe 20.

[0106] The first channel 11 and the second channel 12 generally extend in a straight line direction, that is, the first channel 11 and the second channel 12 both have a length direction.

[0107] In this embodiment, the conveying pipe 20 is centrally located, which helps to discharge dust located in different areas of the first channel 11 or the second channel 12, thus improving the dust removal effect.

[0108] In some embodiments, the dust removal device 100 further includes a fixing member. The fixing member is disposed on the cover 10.

[0109] A fastener is a component that can be connected to other components (such as a laser cleaning device) to fix the position of the cover 10. It can be composed of one or more components.

[0110] The fasteners facilitate the fixing and installation of the cover 10.

[0111] In some embodiments, the first channel 11 and / or the second channel 12 are provided with a fastener 60.

[0112] The first channel 11 and / or the second channel 12 are provided with fasteners 60, including the following situations: First, the first channel 11 is provided with fasteners 60; Second, the second channel 12 is provided with fasteners 60; Third, both the first channel 11 and the second channel 12 are provided with fasteners 60.

[0113] Both the first channel 11 and the second channel 12 are provided in twos. Regardless of which scheme is adopted, the same cover 10 can be fixed by different fasteners 60, which helps to stabilize the cover 10 and other components. In addition, the number of fasteners 60 is small, and the number of parts of the dust removal device is small.

[0114] In addition, under normal circumstances, the two first channels 11 are symmetrically arranged and the two second channels 12 are symmetrically arranged. By adopting the above arrangement, the forces at both ends or sides of the cover 10 can be balanced.

[0115] In some embodiments, the fastener is an L-shaped plate that is connected to the cover 10 by bolts, welding, or other means. This makes the fastener simple in structure and easy to connect.

[0116] In some embodiments, the first channel 11 and the second channel 12 extend in a straight line, and the length of the first channel 11 is greater than the length of the second channel 12.

[0117] Since the electrode 200 is generally a rectangular structure with a long side and a short side, the solution provided in this embodiment allows the first channel 11 to correspond to the long side of the electrode 200, used to absorb dust generated during the cleaning of the long side of the electrode 200. The second channel 12 corresponds to the short side of the electrode 200, used to absorb dust generated during the cleaning of the short side of the electrode 200. This allows the cover 10 to cover the entire cleaning area of ​​the electrode 200 while keeping the volume of the cover 10 relatively small, achieving multiple benefits.

[0118] In some embodiments, the partition 10a is set at an acute angle to the length direction of the first channel 11, and the partition 10a is set at an acute angle to the length direction of the second channel 12.

[0119] The partition 10a is set at an acute angle to the length direction of the first channel 11, meaning that the surface of the partition 10a is set at an acute angle to the length direction of the first channel 11, such as 30°, 45°, 50°, 60°, etc. The partition 10a is set at an acute angle to the length direction of the second channel 12, meaning that the surface of the partition 10a is set at an acute angle to the length direction of the second channel 12, such as 30°, 45°, 50°, 60°, etc.

[0120] By adopting the solution provided in this embodiment, the dust flowing to the area where the partition 10a is located is less likely to get stuck between the angle formed by the partition 10a and the side wall of the cover 10, which helps to discharge the dust.

[0121] In some embodiments, the cover 10 is a one-piece molded structure.

[0122] In this embodiment, the cover 10 can be manufactured by an integral molding process such as casting or die casting.

[0123] The cover 10 adopts a one-piece molded structure, which is structurally stable and easy to manufacture.

The laser cleaning system includes a laser cleaning device and a dust removal device 100 provided in any of the above embodiments, the dust removal device 100 being disposed on the side of the laser cleaning device near the electrode 200.

[0125] The laser cleaning system provided in this application embodiment includes the dust removal device 100 provided in any of the above embodiments, and can achieve the same technical effect, which will not be described in detail here.

[0126] In some embodiments, the dust removal device 100 is connected to the laser cleaning device.

[0127] The dust removal device 100 can be connected to the laser cleaning device via the aforementioned fasteners or other connectors, depending on the specific application. The dust removal device 100 and the laser cleaning device can be fixedly connected or detachably connected. When detachably connected, the dust removal device 100 can be replaced with a corresponding one based on the size of the different electrode plates 200.

[0128] By adopting the solution provided in this embodiment, the dust removal device 100 and the laser cleaning device can be linked. Compared with the dust removal device 100 and the laser cleaning device being controlled to move by drive mechanisms respectively, the number of drive mechanisms can be saved, the number of mechanisms in the laser cleaning system can be reduced, and its manufacturing cost can be reduced.

[0129] like Figures 1 to 3As shown, one embodiment of this application provides a dust removal device 100. The dust removal device 100 includes a hood 10, a conveying pipe 20, and a power enhancement mechanism 30. The hood 10 has an internal suction channel and a partition 10a, which divides the suction channel into staggered first channels 11 and second channels 12. Both the first channel 11 and the second channel 12 have an air inlet 13 and an air outlet. The conveying pipe 20 communicates with either the first channel 11 or the second channel 12 through the air outlet. The power enhancement mechanism 30 is correspondingly arranged with the conveying pipe 20 and is used to enhance the gas flow power within the conveying pipe 20. The power enhancement mechanism 30 is a pneumatic conveyor. The power enhancement mechanism 30 or the conveying pipe 20 is equipped with a throttling valve 40.

[0130] A wind speed detection module 50 is provided on the delivery pipe 20. The wind speed detection module 50 is located on the air outlet side of the power enhancement mechanism 30 and is spaced apart from the power enhancement mechanism 30. The delivery pipe 20 includes a flexible hose 21, which is located between the pneumatic conveyor and the wind speed detection module 50.

[0131] Four conveying pipes 20 are provided, arranged around the cover 10, and each of the four conveying pipes 20 is connected to a different channel. Each conveying pipe 20 is located at the middle of the length of its corresponding channel, which is either the first channel 11 or the second channel 12 connected to the conveying pipe 20. The dust removal device 100 also includes a fixing member 60, which is located on the cover 10. Both second channels 12 are equipped with fixing members 60. The fixing members 60 and the air inlet 13 are located on two side walls opposite to the second channels 12, and do not interfere with each other. The first channel 11 and the second channel 12 extend in a straight line, with the length of the first channel 11 being greater than the length of the second channel 12. The partition 10a is set at an acute angle to the length direction of the first channel 11, and also at an acute angle to the length direction of the second channel 12. The cover 10 is a one-piece molded structure.

[0132] The dust removal device 100 can be detachably connected to the laser cleaning device via a fastener. The wind speed detection device is an anemometer.

[0133] The improved structure of the dust collection device 100 enhances dust collection efficiency, thereby improving cleaning efficiency. It can be used in conjunction with a laser cleaning device to achieve high-efficiency cleaning of the electrode 200. The dust collection device provided in this embodiment has advantages such as simple structure and easy quick changeover. Each channel allows for independent adjustment of dust collection efficiency, avoiding the influence of draft eddies on dust collection effects, and allows for independent detection of dust collection wind speed. The improved dust collection device 100 achieves efficient and uniform dust collection, enabling high-efficiency cleaning when used with a laser cleaning device.
