Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to electrode unwinding and threading devices and winding and unwinding equipment. Background Technology

[0002] The turret-type unwinding mechanism of lithium battery manufacturing equipment generally includes a turret assembly, which typically consists of a turret, multiple rollers, and multiple unwinding devices used to mount and unwind the electrode rolls. During the initial unwinding operation or if automatic tape changing fails, the unwound tape is usually guided to the discharge port before being threaded onto downstream production equipment.

[0003] In related technologies, when the first unwinding operation or automatic tape changing fails, the material tape is usually manually moved to the outlet by entering the unwinding equipment. However, this method of moving the tape is inefficient and there is a certain danger and poor safety when manual entry into the equipment is required. Utility Model Content

The tension wheel assembly includes multiple tension wheels. The conveyor belt forms a closed conveying path through the wheels, and the tension wheel assembly is used to adjust the tension of the conveyor belt. The belt-pulling rod is connected to the conveyor belt and can pull the belt along the conveying path to a preset position under the drive of the conveyor belt.

[0008] As an optional embodiment, the tensioning wheel assembly further includes a tensioning drive mechanism, wherein the plurality of tensioning wheels include movable wheels, and the tensioning drive mechanism is used to drive the movable wheels to move in order to change the length of the conveyor belt between the plurality of tensioning wheels.

[0009] As an optional embodiment, the plurality of tensioning rollers further includes a first tensioning roller and a second tensioning roller, the movable roller is located between the first tensioning roller and the second tensioning roller, and the movable roller is connected to the first tensioning roller via a pressure arm; the driving end of the tensioning drive mechanism is movably connected to the end of the pressure arm near the first tensioning roller, and is used to drive the pressure arm to rotate, so as to drive the movable roller to rotate around the first tensioning roller.

[0010] As an optional embodiment, the pressure arm includes an L-shaped arm formed by a first section and a second section vertically connected together. The movable wheel and the first tensioning wheel are respectively disposed at both ends of the first section, and the first tensioning wheel is disposed close to the second section. The driving end of the tensioning drive mechanism is movably connected to the second section and is used to drive the first section to rotate around the second section.

[0011] As an optional embodiment, the tensioning drive mechanism includes:

[0012] A cylinder, wherein the push rod of the cylinder is used to drive the movable wheel to move;

[0013] A controller is connected to the cylinder and is used to control the air pressure input into the cylinder according to the target tension force, so as to adjust the extension or retraction of the cylinder push rod.

[0014] As an optional embodiment, the electrode unwinding and threading device further includes a lifting mechanism, which includes a cutter assembly mounted on the frame and capable of moving up and down along the vertical direction of the frame, and a follower wheel mounted on the cutter assembly; and when the cutter assembly moves up and down, the follower wheel can rise to lift the conveyor belt or fall away from the conveyor belt, and the tension wheel assembly can synchronously adjust the tension of the conveyor belt.

[0015] As an optional embodiment, the drive wheel is located at the preset position and is located diagonally above the tension wheel assembly, and the conveyor belt between the drive wheel and the tension wheel assembly is inclined.

[0016] As an optional embodiment, the threading mechanism further includes a rotary drive mechanism connected to the drive wheel and used to drive the drive wheel to rotate.

[0017] As an optional embodiment, the threading mechanism further includes a drive rod, the rotary drive mechanism is connected to the drive rod and is used to drive the drive rod to rotate; the drive wheel is disposed on the drive rod and can rotate synchronously with the drive rod.

[0018] A second aspect of this application also provides a winding and unwinding device, comprising:

[0019] A turret, wherein the turret is provided with multiple rollers for mounting material rolls, and the multiple rollers can rotate with the turret;

[0020] In the aforementioned electrode unwinding and threading device, the frame is positioned relative to the turret, and the roller can rotate to a position above the frame so that the unwound strip on the roller can be threaded onto the guide rod.

[0021] As an optional embodiment, the winding and unwinding equipment further includes an outer protective frame, which is mounted outside the turret and has a discharge port that corresponds to the preset position.

[0022] The technical solution provided in this application may include the following beneficial results:

[0023] When the initial unwinding operation or automatic tape changing fails, the tape on the roll falls vertically under gravity. The end of the fallen tape can be threaded onto the guide bar, achieving automatic tape threading. The rotation of the drive wheel drives the conveyor belt along the conveyor path, which in turn drives the guide bar connected to the conveyor belt to move synchronously. This moves the tape threaded onto the guide bar to the preset position, achieving automatic tape threading and avoiding manual entry into the equipment for tape threading and threading operations, thus reducing safety risks. When the contact between the conveyor belt and the pulleys is too tight or too loose, the tension of the conveyor belt can be adjusted through the tensioning pulley assembly to achieve stable tape conveying, improve electrode production efficiency, and reduce safety risks.

[0024] The technical solution of this application can also:

[0025] Because the belt threading mechanism and the cutter assembly are integrated into the frame in this application, when the cutter assembly moves up and down according to its original workflow, it may cause interference between the belt threading action of the belt threading mechanism and the cutter assembly. For example, when the cutter assembly rises above the conveyor belt, the belt guide lever may be unable to pass the cutter assembly and move to the preset position. To prevent interference, this embodiment of the application adds a follower wheel to the cutter assembly, so that the follower wheel rises synchronously when the cutter assembly rises, and can lift the conveyor belt, preventing the cutter assembly from interfering with the belt guide lever's belt-pulling operation. Simultaneously, as the follower wheel rises and falls, the conveyor belt is lifted or loosened, causing changes in the conveyor belt tension. This may cause the conveyor belt to fall off the wheels or become too tightly engaged with the wheels, resulting in slow conveyor belt movement. This embodiment of the application further uses a tensioning wheel assembly to synchronously adjust the conveyor belt tension to prevent the conveyor belt from falling off the wheels or moving too slowly. Therefore, the electrode unwinding and threading device of this application can integrate the threading mechanism and the cutting assembly, and can automatically guide the unwound electrode strip to the discharge port without affecting the operation of the cutting assembly, thereby improving electrode production efficiency and reducing safety risks.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] When the initial unwinding or automatic tape change fails, the unwound tape usually needs to be guided to the outlet before being threaded onto the downstream production equipment. In related technologies, when the initial unwinding or automatic tape change fails, the tape is typically guided to the outlet manually by entering the unwinding equipment. However, this method is inefficient and poses a safety hazard due to the need for manual entry.

[0043] To address the aforementioned issues, this application provides an electrode unwinding and threading device that can automatically guide the electrode strip to the discharge port, thereby improving electrode production efficiency and reducing safety risks.

[0044] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0045] Figure 1 This is a perspective view of the electrode unwinding and threading device shown in the embodiments of this application (the lifting mechanism is descending).

[0046] See Figure 1 This application provides an electrode unwinding and threading device, including a frame 1 and a threading mechanism 3. The threading mechanism 3 includes a belt-pulling rod 30 and a threading assembly 31 mounted on the frame 1. The threading assembly 31 includes a drive wheel 310, a tension wheel assembly 311, and a conveyor belt 312. The drive wheel 310 is rotatably mounted on the frame 1. The tension wheel assembly 311 includes multiple tension wheels 320. The conveyor belt 312 forms a closed conveying path through the wheels, and the tension wheel assembly 311 is used to adjust the tension of the conveyor belt 312. The two ends of the belt-pulling rod 30 are respectively connected to the conveyor belts 312 of the two threading assemblies 31, and can pull the material belt 50 to a preset position 10 along the conveying path under the drive of the conveyor belt 312.

[0047] In this embodiment, the preset position 10 can be an outlet, such as a discharge port. This outlet can be set opposite to the downstream equipment so that the conveyor belt 50 that is pulled to the outlet can be smoothly connected to the conveyor belt on the downstream equipment.

[0048] In this application embodiment, the number of the belt threading assembly 31 can be set to one, two, or more, and this application does not limit this. When the belt threading assembly 31 is set to one, the middle of the belt-pulling rod 30 is connected to the conveyor belt 312, and the material belt 50 can be threaded through either end of the belt-pulling rod 30, moving with the belt-pulling rod 30 to the preset position 10. When the belt threading assembly 31 is set to two, the two belt threading assemblies 31 are respectively arranged on both sides of the frame 1, the belt-pulling rod 30 is arranged laterally between the two belt threading assemblies 31, and the two ends of the belt-pulling rod 30 are connected to the conveyor belt 312 of the two belt threading assemblies 31, and the material belt 50 can be threaded through the middle of the belt-pulling rod 30, moving with the belt-pulling rod 30 to the preset position 10. When multiple threading assemblies 31 are set, and multiple threading assemblies 31 are spaced apart on the frame 1, the pull rod 30 is horizontally arranged between multiple threading assemblies 31, and the pull rod 30 is connected to the conveyor belt 312 of multiple threading assemblies 31, the material strips 50 of different material rolls 5 can be threaded onto the pull rod 30 between two adjacent threading assemblies 31, so as to realize the threading of multiple material strips 50.

[0049] The working principle of the electrode unwinding and threading device in this embodiment is as follows:

[0050] When the initial unwinding operation or automatic tape changing fails, the tape 50 on the material roll 5 falls vertically under gravity. The end of the fallen tape 50 can be threaded onto the guide bar 30, achieving automatic tape threading. The rotation of the drive wheel 310 drives the conveyor belt 312 to move along the conveyor path, thereby causing the guide bar 30 connected to the conveyor belt 312 to move synchronously. This moves the tape 50 threaded onto the guide bar 30 to the preset position 10, achieving automatic tape threading and avoiding manual entry into the equipment for tape threading and threading operations, thus reducing safety risks. When the contact between the conveyor belt 312 and the wheels is too tight or too loose, the tension of the conveyor belt 312 can be adjusted through the tension wheel assembly 311 to achieve stable conveying of the tape 50, improve electrode production efficiency, and reduce safety risks.

[0051] As an optional embodiment, the electrode unwinding and threading device further includes a lifting mechanism 2. The lifting mechanism 2 includes a cutter assembly 20 mounted on the frame 1 and capable of moving up and down in the vertical direction of the frame 1, and a follower wheel 21 mounted on the cutter assembly 20. When the cutter assembly 20 moves up and down, the follower wheel 21 can rise to lift the conveyor belt 312 or fall away from the conveyor belt 312, and the tension wheel assembly 311 can synchronously adjust the tension of the conveyor belt 312.

[0052] In this embodiment, the frame 1 can be the frame of the winding and unwinding equipment that originally has the cutter assembly 20 installed. By adding the threading mechanism 3 to the original frame, the cutter assembly 20 and the threading mechanism 3 can be integrated. The threading mechanism 3 can be installed and operated within the limited space of the winding and unwinding equipment without disassembling or changing the existing equipment, which can improve the integration and applicability of the equipment.

[0053] During the unwinding of the electrode sheet, the cutter assembly 20 can perform corresponding actions according to the original workflow. For example, after unwinding, the cutter assembly 20 rises to meet the material roll and cuts the material strip 50; or, the cutter assembly 20 rises and falls with the change of the material roll diameter to adapt to material rolls of different diameters.

[0054] In this embodiment, when the cutter assembly 20 rises above the conveyor belt 312, the belt-pulling lever 30 may be unable to move past the cutter assembly 20 to the preset position 10. To prevent interference, this embodiment adds a follower wheel 21 to the cutter assembly 20, so that the follower wheel 21 rises synchronously when the cutter assembly 20 rises, and can lift the conveyor belt 312, preventing the cutter assembly 20 from interfering with the belt-pulling operation of the belt-pulling lever 30. Simultaneously, as the follower wheel 21 rises and falls, the conveyor belt 312 is lifted or relaxed, causing a change in the tension of the conveyor belt 312. This may cause the conveyor belt 312 to fall off the wheels, or to be too tightly engaged with the wheels, resulting in the conveyor belt 312 moving too slowly. This embodiment further uses a tensioning wheel assembly 311 to synchronously adjust the tension of the conveyor belt 312 to prevent the conveyor belt 312 from falling off the wheels or moving too slowly. Therefore, the electrode unwinding and threading device of this application embodiment can integrate the threading mechanism 3 and the cutter assembly 20, and can automatically guide the unwound electrode strip 50 to the discharge port without affecting the operation of the cutter assembly 20, thereby improving electrode production efficiency and reducing safety risks.

[0055] Since the threading mechanism 3 and the cutter assembly 20 are integrated on the frame 1 in this embodiment, when the cutter assembly 20 moves up and down according to its original workflow, it may cause interference between the threading action of the threading mechanism 3 and the cutting action of the cutting assembly 20. For example, when the cutter assembly 20 rises above the conveyor belt 312, the pull rod 30 may not be able to pass over the cutter assembly 20 to move to the preset position 10. To prevent interference, this embodiment adds a follower wheel 21 to the cutter assembly 20 so that the follower wheel 21 rises synchronously when the cutter assembly 20 rises, and can lift the conveyor belt 312 to prevent the cutter assembly 20 from interfering with the pull rod 30's pull operation. At the same time, as the follower wheel 21 rises and falls, the conveyor belt 312 is lifted or relaxed, which will cause the tension of the conveyor belt 312 to change. This may cause the conveyor belt 312 to fall off the wheels, or be too tightly engaged with the wheels, causing the conveyor belt 312 to move too slowly. This embodiment further adjusts the tension of the conveyor belt 312 synchronously via the tensioning wheel assembly 311 to prevent the conveyor belt 312 from slipping off or moving too slowly. Therefore, the electrode unwinding and threading device of this embodiment integrates the threading mechanism 3 with the cutter assembly 20, and automatically guides the unwound electrode strip 50 to the discharge port without affecting the operation of the cutter assembly 20, thereby improving electrode production efficiency and reducing safety risks.

[0056] Optionally, the tensioning wheel assembly 311 also includes a tensioning drive mechanism 330, wherein the plurality of tensioning wheels 320 include a movable wheel 331, and the tensioning drive mechanism 330 is used to drive the movable wheel 331 to move in order to change the length of the conveyor belt 312 between the plurality of tensioning wheels.

[0057] See Figures 1 to 3 These figures illustrate the working state of the tensioning wheel assembly 311 when the cutter assembly 20 descends. Specifically, since the conveyor belt 312 is a closed connection with a constant total length, when the cutter assembly 20 descends, the section of the conveyor belt 312 that was lifted by the follower wheel 21 is released and is in a loose state. The tensioning drive mechanism 330 drives the movable wheel 331 to move, thereby increasing the length of the conveyor belt 312 between the multiple tensioning wheels, thus achieving tension of the conveyor belt 312 and preventing the conveyor belt 312 from falling off the wheels.

[0058] See Figures 4 to 6 These figures illustrate the working state of the tensioning wheel assembly 311 when the cutter assembly 20 rises. Specifically, since the conveyor belt 312 is a closed connection with a constant total length, when the cutter assembly 20 rises, the section of the conveyor belt 312 that is lifted by the follower wheel 21 is in a tensioned state. The tensioning drive mechanism 330 drives the movable wheel 331 to move, thereby shortening the length of the conveyor belt 312 between the multiple tensioning wheels. This prevents the tension of the lifted section of the conveyor belt 312 from becoming too high and prevents the conveyor belt 312 from being over-tensioned and slowing down its movement.

[0059] Preferably, the plurality of tensioning rollers 320 further includes a first tensioning roller 332 and a second tensioning roller 333, and a movable roller 331 is located between the first tensioning roller 332 and the second tensioning roller 333, and the movable roller 331 is connected to the first tensioning roller 332 through a pressure arm 334; the driving end of the tensioning drive mechanism 330 is movably connected to the end of the pressure arm 334 near the first tensioning roller 332, and is used to drive the pressure arm 334 to rotate, so as to drive the movable roller 331 to rotate around the first tensioning roller 332.

[0060] See Figures 1 to 3 Specifically, in this embodiment, a first tensioning wheel 332, a movable wheel 331, and a second tensioning wheel 333 are provided, and these three tensioning wheels are arranged in an S-shape. The movable wheel 331 is not fixed. When the cutter assembly 20 rises and the conveyor belt 312 is released, the driving end of the tensioning drive mechanism 330 drives one end of the pressure arm 334 to rotate, thereby causing the movable wheel 331 connected to the other end of the pressure arm 334 to rotate clockwise around the first tensioning wheel 332, increasing the distance between the movable wheel 331 and the second tensioning wheel 333, thereby increasing the length of the conveyor belt 312 between the first tensioning wheel 332, the movable wheel 331, and the second tensioning wheel 333.

[0061] See Figures 4 to 6Specifically, when the cutter assembly 20 descends and the conveyor belt 312 is lifted, the drive end of the tension drive mechanism 330 drives one end of the pressure arm 334 to rotate, thereby causing the movable wheel 331 connected to the other end of the pressure arm 334 to rotate counterclockwise around the first tension wheel 332, reducing the distance between the movable wheel 331 and the second tension wheel 333, thereby reducing the length of the conveyor belt 312 between the first tension wheel 332, the movable wheel 331, and the second tension wheel 333.

[0062] More preferably, the pressure arm 334 includes an L-shaped arm formed by the vertical connection of a first segment 3340 and a second segment 3341. The movable wheel 331 and the first tension wheel 332 are respectively disposed at both ends of the first segment 3340, and the first tension wheel 332 is disposed close to the second segment 3341. The driving end of the tensioning drive mechanism 330 is movably connected to the second segment 3341 and is used to drive the first segment 3340 to rotate around the second segment 3341.

[0063] See Figure 3 and Figure 6 In this embodiment, the pressure arm 334 is generally L-shaped. The length of the first segment 3340 is greater than that of the second segment 3341. The two ends of the first segment 3340 are provided with movable wheels 331 and first tensioning wheels 332. In order to reduce the weight of the first segment 3340 and realize the flexible rotation of the movable wheels 331, the width of the first segment 3340 is adapted to the diameter of the movable wheels 331 and the first tensioning wheels 332. In order to connect the drive end of the tensioning drive mechanism 330, the second segment 3341 is provided to realize the connection between the tensioning drive mechanism 330 and the pressure arm 334.

[0064] Preferably, see Figure 7 The tensioning drive mechanism 330 includes a cylinder 3301 and a controller 3302. The push rod of the cylinder 3301 is used to drive the movable wheel 331 to move. The controller 3302 is connected to the cylinder 3301 and is used to control the air pressure input into the cylinder 3301 according to the target tension force, so as to adjust the extension or retraction of the push rod of the cylinder 3301.

[0065] In this embodiment, the controller 3302 can be an electro-proportional valve connected to an air source. It can control the air pressure in the input cylinder 3301 in real time based on a preset target tension force, thereby adjusting the extension or retraction of the push rod of the cylinder 3301 to achieve precise tension control. For example, the greater the extension of the cylinder 3301, the greater the counterclockwise rotation of the movable wheel 331; conversely, the greater the retraction of the cylinder 3301, the greater the clockwise rotation of the movable wheel 331.

[0066] Optionally, the drive wheel 310 is located at a preset position 10 and is located diagonally above the tension wheel assembly 311, and the conveyor belt 312 between the drive wheel 310 and the tension wheel assembly 311 is inclined.

[0067] See Figure 1 and Figure 3 In this embodiment, the specific location of the preset position 10 is not limited, but it is preferably located at a high position to facilitate the next step of processing, such as connecting the conveyor belt 50 to the outlet, by the staff. By setting the drive wheel 310 at the preset position 10, the drive wheel 310 can be easily driven.

[0068] In this embodiment, the electrode unwinding and threading device can be set below the turret 4. When the material roll 5 on the roller 40 of the turret 4 is fed for the first time or the automatic belt changing fails, the material strip 50 at the beginning of the material roll 5 falls vertically. In order to make the falling material strip 50 fit perfectly on the belt-pulling rod 30, in this embodiment, the initial position of the belt-pulling rod 30 is set below the material roll 5, and the tension wheel assembly 311 is set at the initial position of the belt-pulling rod 30. After this setting, the tension wheel assembly 311 is located below and the drive wheel 310 is located above, so that the belt-pulling rod 30 tilts upward to pull the material strip 50 to the preset position.

[0069] Optionally, the threading mechanism 3 also includes a rotary drive mechanism 34, which is connected to the drive wheel 310 and is used to drive the drive wheel 310 to rotate.

[0070] See Figure 2 and Figure 5 In this embodiment of the application, the rotary drive mechanism 34 is used to drive the drive wheel 310 to rotate, thereby moving the conveyor belt 312. The rotary drive mechanism 34 can be an electric device or a manual device, and this application does not limit it in this regard.

[0071] Preferably, the threading mechanism 3 further includes a drive rod 35, a rotary drive mechanism 34 connected to the drive rod 35 and used to drive the drive rod 35 to rotate; the drive wheel 310 is disposed on the drive rod 35 and can rotate synchronously with the drive rod 35. See also Figure 1 and Figure 2 ,as well as Figure 4 and Figure 5 Taking two belt threading assemblies 31 as an example, in order to achieve synchronous movement of the conveyor belts 312 of the two belt threading assemblies 31, a drive rod 35 is set to connect the two drive wheels 310 of the two belt threading assemblies 31. By driving the drive rod 35 to rotate, the two drive wheels 310 of the two belt threading assemblies 31 can be rotated synchronously, thereby enabling the belt puller 30 to move stably with the two conveyor belts 312 of the two belt threading assemblies 31.

[0072] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a winding and unwinding device and corresponding embodiments.

[0073] See Figure 8This application embodiment also provides a winding and unwinding device, including a turret 4 and the aforementioned electrode unwinding and threading device. The turret 4 is provided with a plurality of rollers 40 for mounting the material roll 5, and the plurality of rollers 40 can rotate with the turret 4. The frame 1 of the electrode unwinding and threading device is arranged relative to the turret 4, and the rollers 40 can rotate to above the frame 1 so that the material strip 50 unwound on the rollers 40 can be threaded onto the guide rod 30.

[0074] In this embodiment, the electrode unwinding and threading device can be located below the turret 4. When the material roll 5 on the roller 40 of the turret 4 is fed for the first time or when the automatic belt changing fails, the material strip 50 at the beginning of the material roll 5 falls vertically. The fallen material strip 50 (see...) Figure 8 The material strip 50 (represented by the dashed line) can be precisely threaded onto the guide rod 30, thereby moving the material strip 50 to a preset position via the movement of the guide rod 30 (see [reference]). Figure 8 The solid line represents the 50mm strip.

[0075] In this embodiment, the frame 1 can be the frame on which the cutter assembly 20 is originally installed in the winding and unwinding equipment. By adding the threading mechanism 3 to the original frame, the cutter assembly 20 and the threading mechanism 3 can be integrated.
