[0002] The cutting of battery electrode tabs is generally done using laser cutting. This process generates a large amount of metal dust, which, when released into the air, not only affects the quality of the produced batteries but also poses a health hazard to operators. Currently, traditional dust removal systems for laser cutting suffer from the following problems: low dust removal efficiency and inability to respond in real time to changes in dust concentration; fixed wind speed in the dust removal device, resulting in high energy consumption and unstable performance. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a battery processing system that uses multiple sensors to monitor dust concentration in real time. A PLC controller receives the dust concentration information and adjusts the dust removal airflow to achieve dynamic dust removal and ensure equipment cleanliness.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A battery processing system, comprising: The dust removal device at the cutting station is partially enclosed within the laser cutting position and includes a lower dust removal pipe located below the cutting position for directly removing dust generated during cutting. A waste interception device is connected to the lower end of the lower dust removal pipe to block waste that is sucked into the lower dust removal pipe due to excessive dust removal wind speed. The discharge device includes a waste conveying device, which is close to the dust removal device at the cutting station and located below the laser cutting position, and is used to convey the cutting waste to the waste disposal area. A space dust removal device, located near the cutting station dust removal device, includes a space dust removal pipe for removing dust that escapes from the cutting station dust removal device; The regulating system includes a PLC controller, which is communicatively connected to the lower dust removal duct and the space dust removal duct, respectively, and is used to control the wind speed of the two ducts.

[0005] This invention utilizes a cutting station dust removal device, a space dust removal device, and a dust removal pipeline to achieve integrated dust removal, ensuring that the dust concentration of the equipment is below the threshold.

[0006] Preferably, in the battery processing system, the dust removal device at the cutting station further includes an upper dust removal pipe and an upper positive pressure dust blocking component, both of which are located above the cutting position and cooperate with each other to form an air wall above the cutting position, for secondary removal of the high-speed dust that splashes upward during cutting, while preventing the high-speed dust from damaging the laser lens.

[0007] Preferably, in the battery processing system, the upper positive pressure dust-blocking component is an air nozzle with its opening facing the cutting position, used to introduce positive pressure gas above the cutting position.

[0008] Preferably, in the battery processing system, the waste interception device includes a guardrail and a first proportional solenoid valve. The first end of the guardrail is connected to the lower end of the lower dust removal pipe, and the second end is connected to the first proportional solenoid valve. The first proportional solenoid valve is communicatively connected to the PLC controller to control the wind speed of the lower dust removal pipe.

[0009] Preferably, in the battery processing system, the discharge device further includes a negative pressure suction pipe detachably connected to the waste conveying device, the negative pressure suction pipe being used to provide negative pressure to the surface of the conveyor belt of the waste conveying device.

[0010] Preferably, in the battery processing system, the rotational speed of the conveyor belt needs to be greater than the running speed of the electrode sheets.

[0011] Preferably, in the battery processing system, the wall of the space dust removal pipe is evenly arranged with several small holes.

[0012] Preferably, in the battery processing system, the space dust removal device further includes a second proportional solenoid valve, which is installed on the space dust removal duct and communicates with the PLC controller to control the airflow speed of the space dust removal duct.

[0013] Preferably, the regulating system of the battery processing system further includes a dust detector and a wind speed detector. The dust detector is distributed on the dust removal device at the cutting station and around the entire system. The wind speed detector is distributed on the lower dust removal pipe and the space dust removal pipe.

[0014] Preferably, the space dust removal device in the battery processing system further includes an FFU system that is communicatively connected to the PLC controller, located at the top of the entire system, for blowing out clean air to ensure the cleanliness of the entire system.

[0015] The present invention has the following advantages due to the adoption of the above technical solutions: 1. The FFU system and the space dust removal device of the present invention are controlled in a coordinated manner: the air blowing of the FFU system and the air suction of the space dust removal device form a directional airflow to maintain the dust concentration inside the system up to standard.

[0016] 2. The present invention provides an upper dust removal pipe and an upper positive pressure dust blocking component above the cutting position. The two work together to form an air wall above the cutting position, which is used to remove the high-speed dust that splashes upward during cutting, and at the same time prevent the high-speed dust from damaging the laser lens.

[0017] 3. This invention utilizes a dust removal device at the cutting station to directly remove dust from the cutting position. At the same time, a guardrail is added to the lower end of the dust removal pipe to prevent excessive dust removal wind speed from causing electrode waste to enter the pipe and cause blockage.

[0018] 4. The present invention sets up dust detectors around the dust removal device at the cutting station and the entire system, and sets up wind speed detectors on the lower dust removal pipe and the space dust removal pipe. The dust detectors monitor the changes in dust concentration in real time, and the PLC controller dynamically adjusts the wind speed of the dust removal device at the cutting station and the space dust removal device according to the detection results. Different dust concentrations correspond to different wind speeds, which achieves both dust removal effect and energy saving effect.

[0019] 5. The negative pressure suction pipe of the present invention is used to provide negative pressure to the surface of the conveyor belt of the waste conveying device. After the electrode tab is cut off at the cutting position, the remaining electrode tab waste falls stably into the waste placement area under the action of inertia and the traction force provided by the conveyor belt.

[0024] The cutting of battery electrode tabs is generally done using laser cutting. This process generates a large amount of metal dust, which, when released into the air, not only affects the quality of the produced batteries but also poses a health hazard to operators. Currently, traditional dust removal systems for laser cutting suffer from the following problems: low dust removal efficiency and inability to respond in real time to changes in dust concentration; fixed wind speed in the dust removal device, resulting in high energy consumption and unstable performance.

[0025] To address the aforementioned technical issues, this invention provides a battery processing system that utilizes a cutting station dust removal device, a space dust removal device, and a dust removal pipeline in a coordinated manner to achieve integrated dust removal, ensuring that the dust concentration of the equipment remains below the threshold.

[0026] like Figure 5 As shown, the battery processing system of the present invention includes: The cutting station dust removal device 1 is partially enclosed within the laser cutting position and includes a lower dust removal duct 11 located below the cutting position for directly removing dust generated during cutting; a waste interception device 2 is connected to the lower end of the lower dust removal duct 11 to block waste material that is sucked into the lower dust removal duct 11 due to excessive dust removal wind speed; a discharge device 3 includes a waste conveying device 32, which is close to the cutting station dust removal device 1 and located below the laser cutting position for conveying cutting waste to the waste disposal area; a spatial dust removal device 4 is located near the cutting station dust removal device 1 and includes a spatial dust removal duct 41 for removing dust that escapes from the cutting station dust removal device 1; and an adjustment system includes a PLC controller, which is communicatively connected to both the lower dust removal duct 11 and the spatial dust removal duct 41 for controlling the wind speed of the two ducts.

[0027] Furthermore, in a preferred embodiment of the invention, such as Figure 6 , 7 As shown, the dust removal device 1 at the cutting station also includes an upper dust removal duct 12 and an upper positive pressure dust blocking component 13, both located above the cutting position. The upper dust removal duct 12 and the upper positive pressure dust blocking component 13 work together to form an air wall above the cutting position, performing secondary removal of the high-speed dust that splashes upward during cutting, while simultaneously preventing the high-speed dust from damaging the laser lens. Preferably, the upper positive pressure dust blocking component 13 is an air nozzle with its opening facing the cutting position, used to introduce positive pressure air above the cutting position.

[0028] Furthermore, such as Figure 8 , 9As shown, the waste interception device 2 includes a guardrail 21 and a first proportional solenoid valve 22. The first end of the guardrail 21 is connected to the lower end of the lower dust removal duct 11, and the second end is connected to the first proportional solenoid valve 22. The first proportional solenoid valve 22 controls the movement of the valve core by receiving a signal from the PLC controller, thereby controlling the wind speed of the lower dust removal duct 11 to achieve intelligent adjustment. Preferably, there are at least two guardrails 21, each using a transparent acrylic cover. The cover 212 is connected to the guardrail box by a magnet for easy disassembly. When waste is sucked into the duct and intercepted by the guardrail 21, the operator can detect the waste through the cover 212 and clean it directly with tweezers. Even if the operator does not detect it in time, the accumulated waste will affect the wind speed of the lower dust removal duct 11. The wind speed detector 5 detects the wind speed change and sends a signal to the PLC controller. Upon receiving the signal, the PLC controller will remind the operator to clean it in time through the human-machine interface.

[0029] like Figure 10 As shown, the discharge device 3 also includes a negative pressure suction pipe 31, which is connected to the waste conveying device 32 by screws. The negative pressure suction pipe 31 provides negative pressure to the surface of the conveyor belt 321 of the waste conveying device 32, causing the conveyor belt 321 to tightly suck up the electrode tab waste generated during cutting. The conveyor belt 321 is close to the dust removal device 1 at the cutting station. After the electrode tabs are removed at the cutting position, the remaining electrode tab waste falls stably into the waste placement area under the action of inertia and the traction force provided by the conveyor belt 321. The rotation speed of the conveyor belt 321 must be greater than the running speed of the electrode sheet to prevent the waste from being unable to be pulled into the dust removal device 1 at the cutting station in time when the rotation speed is low, which would cause internal blockage. At the same time, the discharge device 3 straightens the electrode tab waste to prevent the lower dust removal pipe 11 of the cutting station dust removal device 1 from sucking up the electrode tab waste due to excessive wind speed, which would cause pipe blockage.

[0030] Furthermore, such as Figure 11 and 12 As shown, the space dust removal device 4 also includes a second proportional solenoid valve 42, located near the cutting station dust removal device 1. The second proportional solenoid valve 42 is installed on the space dust removal duct 41 and is communicatively connected to the PLC controller to control the airflow speed of the space dust removal duct 41. Dust generated during cutting cannot be completely removed in the cutting station dust removal device 1 and will escape into the equipment through the gaps between the tooling. The space dust removal device 4 prioritizes the removal of this dust. The airflow speed of the space dust removal device 4 is controlled by the second proportional solenoid valve 42. Preferably, several small holes are evenly arranged on the wall of the space dust removal duct 41.

[0031] Furthermore, such as Figure 5 , 12As shown, the regulating system also includes a dust detector 5 and an air velocity detector 6. The dust detector 5 is distributed on the dust removal device 1 at the cutting station and around the entire system; the air velocity detector 6 is distributed on the lower dust removal duct 11 and the space dust removal duct 41. Specifically, as... Figure 7 As shown, the dust detector 5 is located above the cutting position. The PLC controller receives the signal transmitted by the dust detector 5 and makes a judgment. Based on the judgment result, it transmits a signal to the first proportional solenoid valve 22 to control the wind speed in the lower dust removal duct 11, thereby realizing intelligent wind speed adjustment. Simultaneously, it receives the signal transmitted by the wind speed detector 6 to determine whether the duct is blocked. The control logic of the PLC controller is as follows: Figure 1-4 As shown.

[0032] Furthermore, the space dust removal device 4 also includes an FFU system 7 that is connected to the PLC controller and is located at the top of the entire system to blow out clean air and ensure the cleanliness of the entire system.

[0033] like Figure 1-4 As shown, when the foil material is stained, or when the laser energy fluctuates, causing dust concentration fluctuations during laser cutting, dust escapes from the dust removal device 1 at the cutting station and is detected by the dust detector 5 next to the device. The signal is transmitted to the PLC controller. The PLC controller controls the second proportional solenoid valve 42 connected to the space dust removal device 4 based on the dust concentration signal changes, thereby adjusting the dust removal airflow of the space dust removal device 4. At the same time, the dust detectors 5 around the equipment detect changes in dust concentration, and the PLC controller controls the FFU system 7 to blow in clean gas to form a directional airflow with the suction air of the space dust removal device 4, maintaining the dust concentration inside the machine at the standard level. When the concentration is lower than the set threshold, the dust removal airflow is reduced to achieve energy saving.

[0034] When the dust detector 5 next to the dust removal device 1 at the cutting station detects an increase in the concentration of escaping dust, it indicates an increase in the dust concentration at the cutting station. The PLC controller controls the opening and closing of the first proportional solenoid valve 22 to increase the air velocity in the lower dust removal duct 11 of the dust removal device 1 at the cutting station. The lower dust removal duct 11 is close to the cutting station, and increasing the air velocity can significantly reduce the dust concentration. However, excessively high dust removal air velocity may suck up the cut electrode waste, causing duct blockage; therefore, a guardrail 21 is added. The waste interception device 3 aims to intercept waste, and the guardrail 21 adopts a double-layer structure for more effective interception.

[0035] The PLC controller establishes a mathematical model (known model) based on the relationship between dust concentration and wind speed. The PLC precisely adjusts the wind speed for different dust concentrations, achieving both dust removal and energy saving. Simultaneously, it controls the wind speed in the lower dust removal duct 11 of the cutting station dust removal device 1 to prevent waste material from being sucked away.

[0036] This invention utilizes the coordinated airflow control of the FFU system 7 (blowing) and the spatial dust removal device 4 (suction) to ensure adequate dust concentration within the equipment. The cutting station dust removal device 1 directly collects dust generated during laser cutting, and its suction pipe is equipped with a guardrail 21 to prevent waste material from clogging the pipe. The cutting station dust removal device 1, the spatial dust removal device 4, and the dust removal pipe work together to ensure efficient dust removal. The guardrail 21 cleans up any electrode waste sucked in due to excessive dust removal airflow. The dust detector 5 and the wind speed detector 6 monitor the dust in real time and send the data to the PLC controller, which dynamically adjusts the dust removal airflow based on the dust concentration. This invention achieves intelligent monitoring and adjustment of laser cutting dust, improving dust removal efficiency and reducing energy consumption.

[0037] Based on the above technical solution, the specific technical effects achieved by the present invention are as follows: 1. The FFU system and the space dust removal device of the present invention are controlled in a coordinated manner: the air blowing of the FFU system and the air suction of the space dust removal device form a directional airflow to maintain the dust concentration inside the system up to standard.

[0038] 2. The present invention provides an upper dust removal pipe and an upper positive pressure dust blocking component above the cutting position. The two work together to form an air wall above the cutting position, which is used to remove the high-speed dust that splashes upward during cutting, and at the same time prevent the high-speed dust from damaging the laser lens.

[0039] 3. This invention utilizes a dust removal device at the cutting station to directly remove dust from the cutting position. At the same time, a guardrail is added to the lower end of the dust removal pipe to prevent excessive dust removal wind speed from causing electrode waste to enter the pipe and cause blockage.

[0040] 4. The present invention sets up dust detectors around the dust removal device at the cutting station and the entire system, and sets up wind speed detectors on the lower dust removal pipe and the space dust removal pipe. The dust detectors monitor the changes in dust concentration in real time, and the PLC controller dynamically adjusts the wind speed of the dust removal device at the cutting station and the space dust removal device according to the detection results. Different dust concentrations correspond to different wind speeds, which achieves both dust removal effect and energy saving effect.

[0041] 5. The negative pressure suction pipe of the present invention is used to provide negative pressure to the surface of the conveyor belt of the waste conveying device. After the electrode tab is cut off at the cutting position, the remaining electrode tab waste falls stably into the waste placement area under the action of inertia and the traction force provided by the conveyor belt.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
