[0002] A lithium battery cell is formed by stacking positive electrode plates, negative electrode plates, and separators in a predetermined order and then hot-pressing them together using a hot-pressing device.

[0003] In the actual production process of lithium battery cells, electrode strips need to be cut into electrode sheets of a predetermined length to meet the requirements of the actual production process using a cutting device. Existing cutting devices typically include a conveying mechanism and a cutting mechanism. The conveying mechanism transports the electrode strips to be cut to the cutting mechanism, which then cuts the electrode strips to obtain electrode sheets of the predetermined length. However, during the conveying process, the electrode sheets may collide with the cutting mechanism due to inertia, causing damage to the electrode sheets and affecting the processing quality and cutting accuracy. Utility Model Content

[0004] The purpose of this application is to provide an electrode cutting device to solve the problem that existing cutting devices may cause the electrode to collide with the cutting mechanism due to inertia during electrode transport.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] This application discloses an electrode cutting device, which includes a conveying mechanism, a carrier, a cutting mechanism, and a fixing mechanism, wherein:

[0008] The carrier is disposed between the conveying mechanism and the cutting mechanism, and the carrier is configured to carry the electrode strip during the conveying of the electrode strip toward the cutting mechanism in a first horizontal direction;

[0009] The cutting mechanism is configured to cut the electrode strip into electrodes of a predetermined length;

[0010] The fixing mechanism is located above the carrier and on the side of the cutting mechanism, and is configured to fix the electrode strip to the carrier before the cutting mechanism cuts the electrode strip.

[0011] This application proposes an electrode cutting device equipped with a fixing mechanism. The fixing mechanism fixes the electrode strip to the carrier before the cutting mechanism cuts the electrode strip, thereby avoiding collision between the electrode strip and the cutting mechanism due to the inertia of the conveying, greatly reducing the defect rate of electrode processing, and improving the processing quality and cutting accuracy of the electrode.

[0012] Optionally, the fixing mechanism includes a mounting plate, a first lifting member, and a clamping member, wherein:

[0013] The first lifting component is movably mounted on the mounting plate, and the clamping component is elastically mounted on the bottom end of the first lifting component. The first lifting component is connected to the cutting mechanism and moves up and down with the cutting mechanism. The first lifting component drives the clamping component to move downward to press the electrode strip against the carrier component.

[0014] By setting the first lifting component to be connected to the cutting mechanism and move up and down synchronously with the cutting mechanism, the cutting mechanism and the first lifting component share a single drive component. The first lifting component does not need to be configured with a separate drive component, resulting in a simple structure and low cost. At the same time, the clamping component is elastically installed on the first lifting component, which enables the clamping component to elastically press the electrode strip against the carrier component, avoiding hard contact between the clamping component and the electrode strip and damage to the electrode strip.

[0015] Optionally, the fixing mechanism also includes a guide rod and an elastic element. The first end of the guide rod is fixedly connected to the clamping element, and the second end of the guide rod is slidably connected to the first lifting element. The elastic element is sleeved on the guide rod, and the top end of the elastic element abuts against the first lifting element, while the bottom end of the elastic element abuts against the clamping element.

[0016] By setting a guide rod, the lifting and lowering of the first lifting component can be guided, thereby improving the stability and reliability of the lifting and lowering of the first lifting component; by sleeve the elastic element on the guide rod and make the two ends of the elastic element abut against the first lifting component and the clamping component respectively, the clamping component is elastically installed on the first lifting component.

[0017] Optionally, the fixing mechanism further includes a second lifting member, a first limiting member, and a second limiting member. The second lifting member is movably mounted on the mounting plate, and the bottom end of the second lifting member is fixedly connected to the clamping member. The first limiting member is adjustablely mounted on the top end of the second lifting member, and the second limiting member is adjustablely mounted on the top end of the first lifting member and abuts against the second lifting member when the first lifting member rises.

[0018] By cooperating with the second lifting component, the first limiting component, the second limiting component, and the first lifting component, the movement stroke of the first lifting component and the second lifting component is limited, thereby adjusting the installation height of the clamping component and providing a stable and reliable fixing mechanism; and the installation positions of the first limiting component and the second limiting component are adjustable, thereby realizing the adjustment of the limiting stroke of the first lifting component and the second lifting component.

[0019] Optionally, the bottom surface of the clamping member near the conveying mechanism is provided with an inwardly downward inclined surface, so as to increase the distance between the feeding side of the clamping member and the carrier.

[0020] By setting an inclined surface on the side of the clamping member close to the conveying mechanism, the distance between the feeding side of the clamping member and the carrier member is increased, which facilitates the feeding of the electrode strip between the clamping member and the carrier member.

[0021] Optionally, the conveying mechanism includes a base frame, a first driving component, a conveying roller, a pressure roller, and a second driving component, wherein:

[0022] The conveyor roller is rotatably mounted on the base frame, the fixed end of the first drive member is mounted on the base frame, the drive end of the first drive member is connected to the conveyor roller, and the first drive member is configured to drive the conveyor roller to rotate.

[0023] The pressure roller is located above the conveyor roller. The fixed end of the second drive component is mounted on the base frame, and the drive end of the second drive component is connected to the pressure roller. The second drive component is configured to drive the pressure roller to move up and down relative to the conveyor roller.

[0024] The second driving component drives the pressure roller to descend a preset height so that the electrode strip is pressed against the conveying roller through the pressure roller. The first driving component drives the conveying roller to rotate so as to convey the electrode strip between the pressure roller and the conveying roller.

[0025] The electrode strip is pressed against the conveyor roller by the cooperation of the second drive component, the pressure roller and the conveyor roller; the electrode strip between the pressure roller and the conveyor roller is conveyed by the cooperation of the first drive component, the conveyor roller and the pressure roller, thus providing a conveying mechanism with high conveying efficiency and precise conveying.

[0026] Optionally, the conveying mechanism also includes a first dust hood and a cleaning brush, wherein:

[0027] The first dust suction hood is set around the conveyor roller, and the dust suction end of the first dust suction hood covers the roller surface of the conveyor roller in the second horizontal direction. The first dust suction hood is connected to the air extraction component through a pipe.

[0028] A cleaning brush is installed at the suction end of the first dust hood. The bristles of the cleaning brush contact the roller surface of the conveyor roller and cover the roller surface of the conveyor roller in the second horizontal direction. The cleaning brush is configured to clean the roller surface of the conveyor roller to remove dust from the roller surface of the conveyor roller.

[0029] The air extraction component draws air from the first dust extraction hood through the pipeline to create a negative pressure that sucks away the dust removed from the surface of the conveyor roller.

[0030] By combining the air extraction component, the first dust suction hood, and the cleaning brush, the automatic cleaning of the conveyor roller surface during the rotation of the conveyor roller is achieved, and the dust brushed off is automatically sucked away, preventing the dust on the conveyor roller surface from adhering to the electrode strip and improving the processing quality of the electrode.

[0033] By combining the air extraction component and the second dust suction hood, the dust on the roller surface of the pressure roller is automatically sucked away, preventing the dust on the roller surface from adhering to the electrode belt, and further improving the processing quality of the electrode.

[0034] Optionally, the cutting mechanism includes a base, a third drive unit, an upper cutter, and a lower cutter, wherein:

[0035] The lower cutter is fixed on the base, and the upper cutter and the lower cutter are staggered. The drive end of the third drive unit is connected to the first lifting unit and the upper cutter. The third drive unit is configured to drive the upper cutter and the first lifting unit to move up and down synchronously.

[0036] Before the third driving component drives the clamping component to descend, the distance between the clamping component and the carrier component is smaller than the distance between the upper cutter and the lower cutter.

[0037] By cooperating with the third drive unit, the upper cutter, and the lower cutter, automatic cutting of the electrode strip passing between the upper and lower cutters is achieved, providing a cutting mechanism with a simple structure and high cutting efficiency. Before the third drive unit drives the clamping member to descend, by setting the distance between the clamping member and the carrier member to be smaller than the distance between the upper and lower cutters, the electrode strip is pressed and fixed on the carrier member by the clamping member before cutting the electrode strip.

[0038] Optionally, the cutting mechanism also includes a third dust suction hood, which is disposed around the lower cutter. The suction end of the third dust suction hood covers the cutting surface of the electrode strip in the second horizontal direction. The third dust suction hood is connected to the air extraction component through a pipe.

[0039] The air extraction component draws air from the third dust extraction hood through the pipeline to create a negative pressure that removes the dust generated when the upper and lower cutters cut the electrode strip.

[0040] By combining the air extraction component and the third dust extraction hood, the dust generated during the cutting of the electrode strip by the upper and lower cutters is automatically sucked away, preventing dust from adhering to the electrode strip and the cut electrode, thus improving the processing quality of the electrode and also improving the cleanliness of the surrounding environment.

[0052] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] A lithium battery cell is formed by stacking positive electrode plates, negative electrode plates, and separators in a predetermined order and then hot-pressing them together using a hot-pressing device.

[0054] In the actual production process of lithium battery cells, electrode strips need to be cut into electrode sheets of a predetermined length to meet the requirements of the actual production process using a cutting device. Existing cutting devices typically include a conveying mechanism and a cutting mechanism. The conveying mechanism transports the electrode strips to be cut to the cutting mechanism, which then cuts the electrode strips to obtain electrode sheets of the predetermined length. However, during the conveying process, the electrode sheets may collide with the cutting mechanism due to inertia, causing damage to the electrode sheets and affecting the processing quality and cutting accuracy.

[0055] Therefore, this application provides an electrode cutting device; please refer to [link / reference]. Figure 1 As shown, the electrode cutting device provided in this embodiment includes a conveying mechanism 10, a carrier 20, a cutting mechanism 30, and a fixing mechanism 40. The conveying mechanism 10 is disposed in front of the cutting mechanism 30, and the conveying mechanism 10 is configured to move the electrode strip to be cut along a first horizontal direction ( Figure 1 The electrode strip is conveyed to the cutting mechanism 30 in the X direction; the carrier 20 is disposed between the conveying mechanism 10 and the cutting mechanism 30, and the carrier 20 is configured to carry the electrode strip during the conveying of the electrode strip toward the cutting mechanism 30 in the first horizontal direction; the cutting mechanism 30 is configured to cut the electrode strip into electrodes of a predetermined length; the fixing mechanism 40 is located above the carrier 20 and disposed on the side of the cutting mechanism 30, and is configured to fix the electrode strip on the carrier 20 before the cutting mechanism 30 cuts the electrode strip.

[0056] Specifically, the support member 20 is a horizontally positioned support plate.

[0057] As can be seen, the electrode cutting device proposed in this application is equipped with a fixing mechanism 40. The fixing mechanism 40 fixes the electrode strip on the carrier 20 before the cutting mechanism 30 cuts the electrode strip, thereby avoiding the electrode strip from colliding with the cutting mechanism 30 due to the inertia of the conveying, greatly reducing the defect rate of electrode processing, and improving the processing quality and cutting accuracy of the electrode.

[0058] Please see Figure 1 and Figure 4 As shown, in one embodiment, the fixing mechanism 40 includes a mounting plate 41, a first lifting member 42, and a pressing member 43. The first lifting member 42 is movably mounted on the mounting plate 41, and the pressing member 43 is elastically mounted on the bottom end of the first lifting member 42. The first lifting member 42 is connected to the cutting mechanism 30 and moves up and down with the cutting mechanism 30. The first lifting member 42 drives the pressing member 43 to move downward to press the electrode strip against the carrier member 20.

[0059] As can be seen, by setting the first lifting member 42 to be connected to the cutting mechanism 30 and follow the cutting mechanism 30 in lifting and lowering motion, the cutting mechanism 30 and the first lifting member 42 share a driving component. The first lifting member 42 does not need to be configured with a separate driving component, which is simple in structure and low in cost. At the same time, the pressing member 43 is elastically installed on the first lifting member 42, which realizes that the pressing member 43 elastically presses the electrode strip against the carrier member 20, avoiding the pressing member 43 from hard contact with the electrode strip and damaging the electrode strip.

[0060] In one embodiment, the fixing mechanism 40 further includes a guide rod 44 and an elastic member 45. The first end of the guide rod 44 is fixedly connected to the clamping member 43, and the second end of the guide rod 44 is slidably connected to the first lifting member 42. The elastic member 45 is sleeved on the guide rod 44, and the top end of the elastic member 45 abuts against the first lifting member 42, and the bottom end of the elastic member 45 abuts against the clamping member 43.

[0061] Specifically, the fixing mechanism 40 includes two guide rods 44 spaced apart and two elastic elements 45, each elastic element 45 corresponding to one guide rod 44, and the elastic element 45 is a helical spring or a mold spring.

[0062] It can be seen that by setting the guide rod 44, the lifting of the first lifting member 42 can be guided, thereby improving the stability and reliability of the lifting of the first lifting member 42; by sleeve the elastic member 45 on the guide rod 44 and make the two ends of the elastic member 45 abut against the first lifting member 42 and the pressing member 43 respectively, the pressing member 43 is elastically installed on the first lifting member 42.

[0063] In one embodiment, the fixing mechanism 40 further includes a second lifting member 46, a first limiting member 47, and a second limiting member 48. The second lifting member 46 is movably mounted on the mounting plate 41, and the bottom end of the second lifting member 46 is fixedly connected to the clamping member 43. The first limiting member 47 is adjustablely mounted on the top end of the second lifting member 46, and the second limiting member 48 is adjustablely mounted on the top end of the first lifting member 42 and abuts against the second lifting member 46 when the first lifting member 42 rises.

[0064] Specifically, the first limiting member 47 includes two limiting blocks spaced apart, each limiting block is fitted with a limiting bolt, and the lower end of the limiting bolt is installed on the corresponding limiting block with adjustable thread height. When the second lifting member 46 rises, the upper end of the limiting bolt of the first limiting member 47 abuts against the upper base frame 11 to limit the rising stroke of the second lifting member 46.

[0065] Specifically, the second limiting member 48 includes two spaced-apart limiting blocks, each with a limiting bolt installed on it. The lower end of the limiting bolt is adjustable in height on the corresponding limiting block via a thread. When the first lifting member 42 rises, the upper end of the limiting bolt of the second limiting member 48 abuts against the second lifting member 46. The first lifting member 42 continues to rise, causing the second lifting member 46 to rise synchronously. By adjusting the installation height of the limiting bolt of the second limiting member 48 on the limiting block, the installation height of the clamping member 43 can be adjusted.

[0066] Specifically, the first lifting component 42 and the second lifting component 46 are both mounted on the mounting plate 41 in a liftable manner via a sliding guide pair composed of a linear guide rail and a slider, and the first lifting component 42 and the second lifting component 46 share a set of linear guide rails.

[0067] As can be seen, through the cooperation of the second lifting member 46, the first limiting member 47, the second limiting member 48 and the first lifting member 42, the movement stroke of the first lifting member 42 and the second lifting member 46 is limited, thereby adjusting the installation height of the clamping member 43 and providing a stable and reliable fixing mechanism 40; and the installation position of the first limiting member 47 and the second limiting member 48 is adjustable, thereby realizing the adjustment of the limiting stroke of the first lifting member 42 and the second lifting member 46.

[0068] Please see Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, the bottom surface of the clamping member 43 near the conveying mechanism 10 is provided with an inclined surface 430 that slopes downward toward the inward side, so that the distance between the feeding side of the clamping member 43 and the carrier member 20 is increased.

[0069] It can be seen that by setting an inclined surface 430 on the side of the clamping member 43 close to the conveying mechanism 10, the distance between the feeding side of the clamping member 43 and the carrier member 20 is increased, which makes it easier for the electrode strip to be fed into the space between the clamping member 43 and the carrier member 20.

[0070] Please see Figure 1As shown, in one embodiment, the conveying mechanism 10 includes a base frame 11, a first driving member 12, a conveying roller 13, a pressure roller 14, and a second driving member 15. The conveying roller 13 is rotatably mounted on the base frame 11. The fixed end of the first driving member 12 is mounted on the base frame 11, and the driving end of the first driving member 12 is connected to the conveying roller 13. The first driving member 12 is configured to drive the conveying roller 13 to rotate. The pressure roller 14 is located above the conveying roller 13. The fixed end of the second driving member 15 is mounted on the base frame 11, and the driving end of the second driving member 15 is connected to the pressure roller 14. The second driving member 15 is configured to drive the pressure roller 14 to rise and fall relative to the conveying roller 13. The second driving member 15 drives the pressure roller 14 to descend a preset height so that the electrode strip is pressed against the conveying roller 13 by the pressure roller 14. The first driving member 12 drives the conveying roller 13 to rotate so as to convey the electrode strip between the pressure roller 14 and the conveying roller 13.

[0071] Specifically, the first driving component 12 includes a motor. The motor's shaft is connected to the shaft of the conveyor roller 13.

[0072] Specifically, the second driving component 15 includes at least one cylinder, the fixed end of which is mounted on the base frame 11, and the driving end of which is connected to the pressure roller 14.

[0073] As can be seen, the electrode strip is pressed against the conveyor roller 13 by the cooperation of the second driving member 15, the pressure roller 14 and the conveyor roller 13; the electrode strip between the pressure roller 14 and the conveyor roller 13 is conveyed by the cooperation of the first driving member 12, the conveyor roller 13 and the pressure roller 14, thus providing a conveying mechanism 10 with high conveying efficiency and precise conveying.

[0074] In one embodiment, the conveying mechanism 10 further includes a first dust suction hood 16 and a cleaning brush 17. The first dust suction hood 16 is disposed around the periphery of the conveying roller 13, and the suction end of the first dust suction hood 16 is in the second horizontal direction ( Figure 1 The first dust suction hood 16 covers the roller surface of the conveyor roller 13 in the Y direction. The first dust suction hood 16 is connected to the air extraction component (not shown in the figure) through a pipe. The cleaning brush 17 is installed at the dust suction end of the first dust suction hood 16. The bristles of the cleaning brush 17 contact the roller surface of the conveyor roller 13 and cover the roller surface of the conveyor roller 13 in the second horizontal direction. The cleaning brush 17 is configured to clean the roller surface of the conveyor roller 13 to remove dust from the roller surface of the conveyor roller 13. The air extraction component draws air from the first dust suction hood 16 through the pipe to form a negative pressure that sucks away the dust removed from the roller surface of the conveyor roller 13.

[0075] It can be seen that by cooperating with the air extraction component, the first dust suction hood 16 and the cleaning brush 17, the automatic cleaning of the roller surface of the conveyor roller 13 is achieved during the rotation of the conveyor roller 13, and the dust brushed off is automatically sucked away, so as to avoid the dust on the roller surface of the conveyor roller 13 from adhering to the electrode belt and improve the processing quality of the electrode.

[0076] In one embodiment, the conveying mechanism 10 further includes a second dust suction hood 18, which is disposed around the pressure roller 14 and moves up and down with the pressure roller 14. The dust suction end of the second dust suction hood 18 covers the roller surface of the pressure roller 14 in the second horizontal direction. The second dust suction hood 18 is connected to an air extraction component through a pipe. The air extraction component draws air from the second dust suction hood 18 through the pipe to form a negative pressure that sucks away the dust on the roller surface of the pressure roller 14.

[0077] It can be seen that, through the cooperation of the air extraction component and the second dust suction hood 18, the dust on the roller surface of the pressure roller 14 is automatically sucked away, preventing the dust on the roller surface of the pressure roller 14 from adhering to the electrode belt, and further improving the processing quality of the electrode.

[0078] Please see Figures 1 to 3 As shown, in one embodiment, the cutting mechanism 30 includes a base 31, a third driving member (not shown in the figure), an upper cutter 32, and a lower cutter 33. The lower cutter 33 is fixed on the base 31, and the upper cutter 32 and the lower cutter 33 are arranged alternately. The driving end of the third driving member is connected to the first lifting member 42 and the upper cutter 32. The third driving member is configured to drive the upper cutter 32 to rise and fall synchronously with the first lifting member 42. Before the third driving member drives the clamping member 43 to descend, the distance between the clamping member 43 and the bearing member 20 is smaller than the distance between the upper cutter 32 and the lower cutter 33.

[0079] Specifically, the third driving component is a drive module consisting of a cylinder, hydraulic cylinder, or motor in conjunction with a transmission assembly. The transmission assembly can be a ball screw pair, a synchronous belt drive pair, or an eccentric wheel linkage mechanism, etc.

[0080] As can be seen, the automatic cutting of the electrode strip passing between the upper cutter 32 and the lower cutter 33 is achieved through the cooperation of the third driving member, the upper cutter 32 and the lower cutter 33, providing a cutting mechanism 30 with a simple structure and high cutting efficiency. Before the third driving member drives the clamping member 43 to descend, by setting the distance between the clamping member 43 and the carrier member 20 to be smaller than the distance between the upper cutter 32 and the lower cutter 33, the electrode strip is pressed and fixed on the carrier member 20 by the clamping member 43 before cutting the electrode strip.

[0081] In one embodiment, the cutting mechanism 30 further includes a third dust suction hood 34, which is disposed around the lower cutter 33. The dust suction end of the third dust suction hood 34 covers the cutting surface of the electrode strip in the second horizontal direction. The third dust suction hood 34 is connected to an air extraction component through a pipe. The air extraction component draws air from the third dust suction hood 34 through the pipe to form a negative pressure that draws away the dust generated when the upper cutter 32 and the lower cutter 33 cut the electrode strip.

[0082] It can be seen that, through the cooperation of the air extraction component and the third dust extraction hood 34, the dust generated during the cutting of the electrode strip by the upper cutter 32 and the lower cutter 33 is automatically sucked away, preventing dust from adhering to the electrode strip and the cut electrode, thus improving the processing quality of the electrode and also improving the cleanliness of the surrounding environment.

[0083] The working principle of the electrode cutting device provided in this application embodiment is as follows:

[0084] S1, the electrode strip is introduced between the conveyor roller 13 and the pressure roller 14, and the second drive unit 15 works to press the electrode strip against the conveyor roller 13.

[0085] S2, the first driving member 12 works to convey the electrode strip between the conveying roller 13 and the pressure roller 14 toward the cutting mechanism 30 to a preset length;

[0086] S3, the third driving component drives the first lifting component 42 and the upper cutting blade 32 to descend synchronously. The first lifting component 42 drives the pressing component 43 to press the electrode strip onto the carrier component 20 first. Then the upper cutting blade 32 descends to the cutting position to cut the electrode strip.

[0087] The electrode cutting device proposed in this application has the following advantages:

[0088] 1) Before the cutting mechanism 30 cuts the electrode strip, the electrode strip is fixed on the carrier 20, which avoids the electrode strip from colliding with the cutting mechanism 30 due to the inertia of the conveyor. This greatly reduces the defect rate of electrode processing and improves the processing quality and cutting accuracy of the electrode.

[0089] 2) The fixing mechanism 40 and the cutting mechanism 30 share a single drive component, which is simple in structure and low in cost;

[0090] 3) The overall structure of the fixing mechanism 40 is compact and occupies little space. Moreover, it adopts a floating clamping method to avoid damaging the electrode strip.

[0091] 4) Both the pressure roller 14 and the conveyor roller 13 are equipped with dust suction covers, which can promptly remove dust from the roller surfaces of the pressure roller 14 and the conveyor roller 13, preventing dust from adhering to the electrode strip and improving the processing quality of the electrode.

[0092] 5) The cutting mechanism 30 is also equipped with a dust suction hood to automatically remove the dust generated during the cutting of the electrode strip, preventing dust from adhering to the electrode strip and the cut electrode, thus improving the processing quality of the electrode and also improving the cleanliness of the surrounding environment.

[0093] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
