Description

Technical Field

[0001] This utility model relates to the field of cylindrical battery production technology, specifically a cylindrical battery electrode slitting machine. Background Technology

[0002] Cylindrical batteries are widely used primary or secondary batteries in consumer electronics, small energy storage devices, and other fields. Their core functional components are the electrodes. The electrodes are mainly divided into positive electrodes and negative electrodes, and are usually composed of current collectors, active material coatings on the surface of current collectors, and separators. They are the key structures for realizing the storage and conversion of electrical energy during the charging and discharging process of the battery. The processing quality and precision of the electrodes are directly related to the charging and discharging performance, cycle life, and safety and stability of cylindrical batteries.

[0003] The production of cylindrical battery electrodes involves several core processes: First, a slurry containing active materials is prepared by stirring. Then, the slurry is evenly coated onto the surface of the current collector. After drying to remove the solvent from the slurry, the electrode thickness and active material density are controlled through a rolling process. Finally, the electrode enters the "electrode slitting" process. Electrode slitting is accomplished using an electrode slitting machine. The equipment uses rotating slitting rollers to cut the large, rolled electrode into narrower sheets that meet the winding requirements of cylindrical battery cells. The slitting accuracy directly affects the tightness and consistency of the subsequent cell winding.

[0004] Existing electrode slitting machines have significant technical defects in practical applications: when the slitting roller contacts and cuts the electrode, heat is continuously generated due to friction. Although there is an air conditioning system in the clean room and the temperature will not rise, traditional slitting machines lack a directional airflow guiding structure, and the airflow speed is slow. The heat generated by the roller is difficult to dissipate efficiently, and long-term accumulation can easily lead to an increase in the temperature of the roller. This may not only reduce the cutting sharpness and service life of the roller, but also affect the dimensional accuracy of the electrode slitting due to the thermal deformation of the roller. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a cylindrical battery electrode slitting machine to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cylindrical battery electrode sheet slitting machine, comprising a base, a blowing fan installed on one side of the top of the base, and a distribution pipe connected to the air outlet of the blowing fan through a first flexible hose, and a nozzle connected to the top of the distribution pipe; an air suction fan installed on the other side of the top of the base, and an air collection hood connected to the air inlet of the air suction fan through a second flexible hose.

[0007] By adopting the above technical solution, the blower provides an airflow source for heat dissipation, which is delivered to the nozzle through the first hose and the distribution pipe to achieve directional heat dissipation of the slitting roller; the suction fan, together with the air collection hood and the second hose, can promptly recover the cooled airflow, reduce the random flow of airflow inside the slitting machine, improve the heat dissipation efficiency of the slitting roller, and reduce the interference of airflow on the electrode slitting.

[0008] Furthermore, the top of the base is provided with a control cabinet, two mounting brackets and a gearbox. Two crossbeams and two slitting rollers are connected between the two mounting brackets, and both slitting rollers are connected to the gearbox. A top cover is placed on the top of the crossbeams. A motor is installed on one side of one of the mounting brackets, and one of the slitting rollers is connected to the output end of the motor.

[0009] By adopting the above technical solution, the base supports all core components, and the mounting frame and crossbeam together fix the slitting cutter roller; the motor drives the slitting cutter roller to rotate by outputting power, and the gearbox adjusts the transmission parameters of the cutter roller to ensure that the two rollers rotate in a matching manner to achieve precise slitting; the top cover can reduce the entry of external debris into the slitting area, ensure the cleanliness of the slitting environment, and provide the basic conditions for the slitting accuracy of the electrode sheets.

[0010] Furthermore, the nozzle is inclined, and the axis of the nozzle is tangent to the outer ring of the slitting roller.

[0011] By adopting the above technical solution, the direction of the heat dissipation airflow can be optimized. The inclined nozzle can make the airflow accurately target the high-temperature area where the slitting roller contacts the electrode, thereby improving the heat removal efficiency and reducing the risk of thermal deformation of the roller. At the same time, the design that the airflow axis is tangent to the outer ring of the roller can reduce the probability of the airflow blowing directly onto the electrode being slit, and prevent the electrode from vibrating or shifting due to the impact of the airflow.

[0012] Furthermore, there are two distribution pipes and two first flexible hoses, and the two distribution pipes are connected to the base and the crossbeam respectively through pipe supports.

[0013] By adopting the above technical solution, comprehensive heat dissipation coverage of the double slitting cutter rollers can be achieved. The two distribution pipes and the first flexible hose correspond to the positions of the two slitting cutter rollers respectively. With the pipe support fixing the distribution pipes, the shaking of the distribution pipes during airflow transmission can be avoided, ensuring stable airflow delivery.

[0014] Furthermore, the nozzles are provided in two groups, with multiple nozzles in each group, and the multiple nozzles in each group are equidistantly distributed, and the two groups of nozzles are arranged in a mirror image.

[0015] By adopting the above technical solution, the uniformity and adaptability of the heat dissipation airflow can be improved. The nozzles distributed at equal intervals in each group can make the airflow act evenly on the surface of the slitting cutter roller, avoiding temperature differences in the cutter roller caused by uneven local heat dissipation. The mirrored setting of the two groups of nozzles can accurately adapt to the symmetrical layout of the two slitting cutter rollers, ensuring that both rollers can obtain a stable and uniform heat dissipation effect.

[0016] Furthermore, the position of the gas collecting hood corresponds to the position of the nozzle, and the gap between the gas collecting hood and the nozzle is greater than the diameter of the slitting roller.

[0017] By adopting the above technical solution, both airflow recovery efficiency and equipment operation safety can be taken into account. The air collection hood and nozzle are positioned to accurately capture the airflow blown out from the nozzle and cooled by the cutter roller, thereby improving the recovery efficiency. The gap between the air collection hood and the nozzle is larger than the diameter of the slitting cutter roller, which can avoid structural interference of the air collection hood during the rotation and disassembly of the cutter roller, and ensure the normal operation of the slitting cutter roller.

[0018] Furthermore, there are two gas collection hoods and two hoses, and the two gas collection hoods are connected to the base and the crossbeam respectively by bolts, and the two gas collection hoods are arranged in a mirror image.

[0019] By adopting the above technical solution, efficient recovery and flexible maintenance of dual-path heat dissipation airflow can be achieved. The two air collection hoods and the second hose correspond to two sets of nozzles, which can simultaneously recover the heat dissipation airflow of the double slitting cutter rollers and avoid airflow residue. The bolt connection method facilitates the installation, disassembly and position adjustment of the air collection hoods, reducing the difficulty of later maintenance. The mirror setting is adapted to the symmetrical layout of the double cutter rollers to ensure that the recovery structure and the heat dissipation structure are matched.

[0020] Furthermore, the cross-section of the gas collection hood is trapezoidal.

[0021] By adopting the above technical solution, the trapezoidal cross-section gas collection hood has a larger opening area compared with the traditional rectangular or circular gas collection hood, which can more efficiently capture the dissipated heat dissipation airflow, reduce the stagnation of airflow inside the slitting machine, further improve the airflow recovery efficiency, and reduce the interference of airflow on electrode slitting.

[0022] Furthermore, a plurality of hose clamps are respectively connected to the outer surface of one of the crossbeams, the back of the other crossbeam, and the back of one of the mounting brackets, and the first hose and the second hose are respectively connected to the plurality of hose clamps.

[0023] By adopting the above technical solution, the stability of the pipeline layout can be improved. The hose clamp can position and fix the first hose and the second hose, avoiding the hose from shaking or shifting due to airflow impact during airflow transmission, and reducing the risk of the hose falling and colliding with the electrode plate or equipment components.

[0024] Furthermore, the exhaust end of the intake fan is connected to an exhaust pipe, and the exhaust pipe is a bend with one end inclined downwards.

[0025] By adopting the above technical solution, the downward-sloping bend design can guide the hot airflow discharged by the suction fan to flow towards the ground, reducing the situation where hot airflow blows directly onto the operator's calves and reducing operational discomfort; at the same time, the hot airflow is discharged towards the ground, which can reduce the probability of it flowing back to the vicinity of the blower, avoid the hot airflow from mixing into the blower airflow, and ensure the stability of the heat dissipation effect.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model, through the arrangement of a purge fan, first hoses, distribution pipes, and nozzles, allows the airflow generated by the purge fan to be flexibly transported to two distribution pipes via two first hoses. The two distribution pipes can then divert the airflow to two sets of equally spaced nozzles, which are inclined and whose axes are tangent to the outer ring of the slitting roller. This not only precisely guides the airflow to the high-temperature area of ​​the slitting roller, improving the efficiency of heat removal from the roller and reducing the risk of decreased sharpness and thermal deformation caused by prolonged high temperatures, but also reduces the probability of the airflow directly blowing onto the battery electrode sheets being slit, thus reducing the possibility of interference from the airflow to the electrode sheets. It can form a directional heat dissipation airflow transmission and action path.

[0028] 2. This utility model, through the arrangement of an air suction fan, a second flexible hose, and an air collection hood, enables the air suction fan to generate negative pressure suction. Combined with the trapezoidal cross-section air collection hood corresponding to the nozzle position, it can efficiently collect the airflow after cooling the slitting roller. This airflow is then transported through the second flexible hose to the air suction fan for discharge. This structure reduces the random flow of cooling airflow inside the slitting machine, lowering the risk of vibration caused by airflow impacting the electrode sheet, thereby reducing problems such as rough edges and dimensional deviations on the electrode sheet caused by the blowing airflow. Furthermore, it accelerates the discharge speed of the hot airflow and allows for the construction of a recovery channel adapted to the cooling airflow.

[0029] 3. The significance of using a flexible hose as the main conveying pipe through the setting of the first and second flexible hoses in this utility model is that the blades on the slitting roller are consumable parts and need to be replaced every once in a while. When replacing them, the top cover needs to be removed or the mounting bracket needs to be removed from the base. If a rigid pipe is used, the pipe will cause obstruction when the mounting bracket is disassembled and installed. However, by using the first and second flexible hoses, the first and second flexible hoses can be moved aside when the mounting bracket is disassembled and installed, without the need to disassemble the pipes; thus reducing interference with the maintenance of existing technology.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] Cylindrical battery electrode slitting machine, such as Figures 1-5 As shown, the system includes a base 1, with a purge fan 9 mounted on one side of the top of the base 1. The outlet of the purge fan 9 is connected to a distribution pipe 11 via a first flexible hose 10. There are two distribution pipes 11 and two first flexible hoses 10. The two distribution pipes 11 are connected to the base 1 and the crossbeam 5 respectively via pipe supports. The top of the distribution pipe 11 is connected to a nozzle 12. There are two sets of nozzles 12, with multiple nozzles in each set. The multiple nozzles 12 in each set are equidistantly distributed. The two sets of nozzles 12 are mirror images of each other and are tilted. The axis of the nozzles 12 is tangent to the outer ring of the slitting roller 7. During the electrode slitting process, the purge fan 9 and the suction fan 13 start synchronously to form a directional airflow circulation system. The blower 9 draws in air from the cleanroom and converts it into a stable blowing airflow. The airflow is transmitted through two first hoses 10. The airflow is then delivered to two distribution pipes 11, which evenly distribute the airflow to two sets of equally spaced nozzles 12. Since the nozzles 12 are inclined and their axes are tangent to the outer ring of the slitting roller 7, the split airflow can precisely act on the high-temperature area where the slitting roller 7 contacts the electrode sheet. This effectively removes heat from the roller, reduces the risk of thermal deformation and sharpness reduction, and decreases the probability of the airflow blowing directly onto the electrode sheet being slit, thus preventing the electrode sheet from shifting due to airflow interference and vibration.

[0040] An air intake fan 13 is installed on the other side of the top of the base 1. The air intake end of the air intake fan 13 is connected to a gas collection hood 16 via a second flexible hose 15. The cross-section of the gas collection hood 16 is trapezoidal, and the position of the gas collection hood 16 corresponds to the position of the nozzle 12. The gap between the gas collection hood 16 and the nozzle 12 is larger than the diameter of the slitting roller 7. Two gas collection hoods 16 and two flexible hoses 15 are provided. The two gas collection hoods 16 are connected to the base 1 and the crossbeam 5 respectively by bolts. The two gas collection hoods 16 are arranged in a mirror image. The air intake airflow and the blowing airflow act synchronously. The negative pressure suction generated by the blower 13 draws air through two air collection hoods 16. The trapezoidal cross-section expands the airflow collection range and efficiently collects the hot airflow after the slitting roller 7 has been cooled. The hot airflow is delivered to the suction blower 13 through two second hoses 15, and finally the airflow is discharged through the exhaust end of the suction blower 13. The airflow recovery generated by the blower 9 avoids the airflow after cooling from flowing randomly inside the slitting machine, reduces the possibility of airflow impacting the electrode sheet and causing vibration, thereby reducing the problems of electrode sheet edge roughness and dimensional deviation, and ensuring slitting accuracy.

[0041] See Figure 1 and Figure 2 In the above embodiment, a control cabinet 2, two mounting brackets 4, and a gearbox 8 are respectively provided on the top of the base 1. Two crossbeams 5 and two slitting rollers 7 are connected between the two mounting brackets 4. Both slitting rollers 7 are connected to the gearbox 8. A top cover 6 is placed on the top of the crossbeams 5. A motor 3 is installed on one side of one of the mounting brackets 4, and one of the slitting rollers 7 is connected to the output end of the motor 3. The equipment is deployed in the clean room required for cylindrical battery production. The base 1 serves as the supporting foundation of the overall structure, providing a stable installation platform for components such as the control cabinet 2, motor 3, and mounting brackets 4. The operator starts the equipment through the control cabinet 2. Once the motor 3 starts, it outputs power to directly drive the slitting roller 7 connected to it to rotate. The gearbox 8 provides transmission to ensure that the two slitting rollers 7 maintain a suitable rotation rhythm. At the same time, the crossbeam 5 and the mounting frame 4 jointly support the core components such as the slitting roller 7 and the top cover 6. The top cover 6 covers the top of the crossbeam 5 and provides basic protection to prevent external debris from entering the slitting area. At this time, the power is generated by the external conveying equipment, and the external guide rollers guide the material to be processed. The whole sheet to be processed is conveyed between the two slitting rollers 7. Through the rotation and cutting of the rollers, the narrow sheet that meets the winding requirements of cylindrical battery cells is completed.

[0042] Example 2:

[0043] Based on the above embodiment 1, in order to increase the structural stability of the first hose 10 and the second hose 15 located above, the following settings are now adopted.

[0044] See Figure 1 and Figure 2In the above embodiment, a plurality of hose clamps 17 are respectively connected to the outer surface of one of the crossbeams 5, the back of another crossbeam 5 and the back of one of the mounting brackets 4. The first hose 10 and the second hose 15 are respectively connected to the plurality of hose clamps 17. The hose clamps 17 are used to position and support the first hose 10 and the second hose 15, so as to prevent the hose from falling off and hitting the electrode during airflow.

[0045] Example 3:

[0046] Based on the above embodiment one, in order to reduce the backflow of hot air and the direct airflow blowing on the calves of the staff, the following settings are now implemented.

[0047] See Figure 2 , Figure 3 and Figure 5 In the above embodiment, the exhaust end of the suction fan 13 is connected to the exhaust pipe 14. The exhaust pipe 14 is a bend, with one end of the exhaust pipe 14 inclined downwards. The downward-inclined bend of the exhaust pipe 14 causes the exhaust airflow to blow obliquely toward the ground, reducing the situation where the airflow blows directly onto the operator's calves, improving operating comfort. In addition, the blown airflow is far away from the purge fan 9, reducing the phenomenon of hot airflow returning to the purge fan 9.

[0048] The implementation principle of this utility model is as follows: First, the equipment is deployed in a clean room required for cylindrical battery production. The base 1 serves as the supporting foundation for the overall structure, providing a stable installation platform for components such as the control cabinet 2, motor 3, and mounting frame 4. The operator starts the equipment through the control cabinet 2. After the motor 3 starts, it outputs power, directly driving the slitting roller 7 connected to it to rotate. The gearbox 8 provides transmission to ensure that the two slitting rollers 7 maintain a suitable rotation rhythm. At the same time, the crossbeam 5 and the mounting frame 4 jointly support the core components such as the slitting roller 7 and the top cover 6. The top cover 6 covers the top of the crossbeam 5 and provides basic protection to prevent external debris from entering the slitting area. At this time, the power is generated by the external conveying equipment, and the external guide rollers provide guidance, etc., to transport the whole sheet to be processed to between the two slitting rollers 7. Through the rotation and cutting of the rollers, the narrow sheet is cut to meet the requirements of the cylindrical battery cell winding.

[0049] During the electrode slitting process, the purge fan 9 and the suction fan 13 start synchronously to form a directional airflow circulation system. The purge fan 9 draws in the air in the clean room and converts it into a stable purge airflow. The airflow is transmitted through two first hoses 10. The upper first hose 10 is positioned and supported by hose clamps 17 to prevent the hose from falling off and hitting the electrode during airflow. The airflow is delivered to two distribution pipes 11 through the two first hoses 10. The two distribution pipes 11 evenly distribute the airflow to two sets of equally spaced nozzles 12. Since the nozzles 12 are inclined and their axis is tangent to the outer ring of the slitting cutter roller 7, the split airflow can accurately act on the high-temperature area where the slitting cutter roller 7 contacts the electrode. This effectively removes heat from the cutter roller, reduces the risk of thermal deformation and sharpness reduction of the cutter roller, and reduces the probability of the airflow blowing directly onto the electrode being slitting, thus preventing the electrode from shifting position due to airflow interference and vibration.

[0050] The suction airflow and the purge airflow work synchronously. The negative pressure suction generated by the suction fan 13 draws air through two air collection hoods 16. The trapezoidal cross-section expands the airflow collection range, efficiently collecting the hot airflow after the slitting roller 7 has cooled down. The hot airflow is delivered to the suction fan 13 through two second hoses 15. The upper second hose 15 is also limited by hose clamps 17. Finally, the airflow is discharged through the exhaust pipe 14 at the outlet of the suction fan 13. The exhaust pipe 14 is a curved pipe with an inclined downward direction, so that the discharged airflow blows obliquely towards the ground, reducing the airflow blowing directly onto the operator's calves and improving operating comfort. The blown airflow is also far away from the purge fan 9, reducing the phenomenon of hot airflow returning to the purge fan 9. The airflow recovery generated by the purge fan 9 avoids the airflow after cooling flowing randomly inside the slitting machine, reducing the possibility of airflow impacting the electrode and causing vibration, thereby reducing the problems of electrode edge roughness and dimensional deviation, and ensuring slitting accuracy.

[0051] When the blades of the slitting roller 7 need to be replaced due to wear from long-term use, first remove the gearbox 8 that is limited by bolts, then remove the gear connected to the end of the slitting roller 7. The gear is keyed. The operator then disconnects the coupling between the slitting roller 7 and the motor 3. After that, the operator can remove the top cover 6 or remove the mounting bracket 4 that is limited by bolts. Since the airflow transmission uses the first hose 10 and the second hose 15, their flexibility allows the hoses to be easily moved aside. The blade replacement operation can be completed without disassembling the pipes, avoiding the obstruction of the maintenance process by rigid pipes, reducing interference with equipment maintenance efficiency, and improving the overall convenience of operation and maintenance. After removing the mounting bracket 4, the operator will remove the crossbeam 5 that is limited by bolts from between the two mounting brackets 4. Then the mounting bracket 4 can be disassembled to facilitate the removal of the slitting roller 7 from the bearings on the two mounting brackets 4.
