[0036] This application provides a feeding device, specifically, an application in a battery production system for feeding separators. The feeding device of this application will be described in detail below with reference to the accompanying drawings.
[0037] According to Figures 1-6This application provides a feeding device, which includes: a support 1; an unwinding mechanism 2 connected to the support 1, the unwinding mechanism 2 being used to place the diaphragm 22 and unwind the diaphragm 22; and a tensioning assembly, the tensioning assembly including a tensioning roller 30, a connecting member 31 and a counterweight 32, the tensioning roller 30 being movably connected to the support 1 along a first direction X, the connecting member 31 being connected to the support 1 and adjacent to the tensioning roller 30 along the first direction X, one end of the connecting member 31 being connected to the tensioning roller 30 and the other end being connected to the counterweight 32, the tensioning roller 30 being used to wind the portion of the diaphragm 22, and the counterweight 32 being used to drive the tensioning roller 30 to move relative to the support 1 along the first direction X through the connecting member 31, so as to adjust the tension of the diaphragm 22.
[0038] Specifically, the first direction X is as follows: Figure 1 The X-axis direction is shown, and the second direction Z is as follows: Figure 1 As shown in the Z-axis direction, the third direction Y is as follows Figure 1 The Y-axis direction is shown. The first direction X, the second direction Z, and the third direction Y intersect each other pairwise, and further, the first direction X, the second direction Z, and the third direction Y are perpendicular to each other pairwise.
[0039] The support 1 includes a side plate 10, which is vertically arranged along the second direction Z. The side plate 10 is used to install the unwinding mechanism 2 and the tensioning assembly. The unwinding mechanism 2 includes a material roll 20 and a drive component 21. The material roll 20 is rotatably connected to the side plate 10, and the drive component 21 is fixedly mounted on the side plate 10. The output end of the drive component 21 is connected to the material roll 20. A diaphragm 22 is provided on the material roll 20. The drive component 21 drives the material roll 20 to rotate according to the material requirements, thereby releasing the material from the diaphragm 22.
[0040] The connecting member 31 and the tensioning roller 30 are arranged adjacent to each other on the side plate 10 along the first direction X, and the tensioning roller 30 is movable on the side plate 10 along the first direction X. One end of the connecting member 31 is fixedly connected to the tensioning roller 30, and the other end is provided with a counterweight 32. After the diaphragm 22 is unloaded from the roll 20, it is partially wound around the tensioning roller 30. Under the action of the gravity of the counterweight 32, the connecting member 31 drives the tensioning roller 30 to move on the side plate 10 along the first direction X, which can achieve tensioning of the diaphragm 22. By adjusting the size or number of counterweights 32, the gravity of the counterweights 32 can be adjusted, thereby controlling the tension of the diaphragm 22 on the tensioning roller 30 and preventing the diaphragm 22 from being stretched and deformed.
[0041] In this embodiment, a connector 31 connects the tension roller 30 and the counterweight 32. Under the weight of the counterweight 32, the tension roller 30 moves on the support 1 to adjust the tension of the diaphragm 22. The tension of the diaphragm 22 on the tension roller 30 can be adjusted by changing the size or number of counterweights 32. Compared with pneumatic or electric mechanisms, this reduces the cost of the feeding device. Furthermore, since the weight of the counterweight 32 is stable and reliable, it is not limited by power supply or other conditions, thus improving the reliability of the tensioning assembly in adjusting the tension. In addition, by adjusting the number or weight of the counterweights 32, precise control of the tension from zero to any desired tension can be achieved, improving the flexibility and accuracy of tension adjustment.
[0042] In some optional embodiments, the connector 31 includes a connecting wheel 310 and a connecting line 311. The connecting wheel 310 is connected to the bracket 1 and is disposed adjacent to the tension roller 30 along the first direction X. The connecting line 311 is wound around the connecting wheel 310, and one end of the connecting line 311 is connected to the tension roller 30. The counterweight 32 is detachably connected to the other end of the connecting line 311.
[0043] Specifically, such as Figures 2-5 As shown, the connecting wheel 310 can be fixedly connected to the side plate 10 of the bracket 1 and is arranged adjacent to the tension roller 30 along the first direction X. The connecting wheel 310 is used to provide a fulcrum for the connecting line 311 to be wound around, so that the connecting line 311 can slide smoothly on the connecting wheel 310.
[0044] One end of the connecting line 311 is fixedly connected to the tension roller 30, and the counterweight 32 is detachably connected to the other end of the connecting line 311. The connecting line 311 passes around the connecting wheel 310, forming a mechanical transmission system, so that the gravity of the counterweight 32 along the second direction Z can be converted into a tension force that moves the tension roller 30 along the first direction X through the connecting line 311 and the connecting wheel 310. That is, when the gravity of the counterweight 32 acts on the connecting line 311, the connecting line 311 will pull the tension roller 30 to move along the first direction X on the side plate 10, thereby achieving tensioning of the diaphragm 22. By adjusting the size or number of counterweights 32, the magnitude of the tension force acting on the connecting line 311 can be changed, thereby achieving precise control of the tension of the diaphragm 22 on the tension roller 30.
[0045] In this embodiment, tension force is controlled by a few simple mechanical components: connecting wheel 310, connecting line 311, and counterweight 32. Compared to pneumatic or electric mechanisms, this eliminates the need for complex compressed air systems or expensive components such as motors, further reducing the manufacturing cost of the feeding device. Furthermore, the gravity of the counterweight 32 can be more precisely supplied to the tension roller 30 through the connecting line 311 and connecting wheel 310, further improving the reliability of the tensioning assembly in adjusting the tension force.
[0046] In some optional embodiments, the connecting wheel 310 can also rotate relative to the side plate 10 of the connecting bracket 1. This reduces friction when the connecting line 311 slides on the surface of the connecting wheel 310, reduces wear between the connecting line 311 and the connecting wheel 310, extends the service life of both the connecting wheel 310 and the connecting line 311, and thus lowers the replacement cost of the feeding device. Furthermore, the rotating tension wheel allows the connecting line 311 to transmit tension more smoothly, avoiding uneven force transmission caused by jamming or blockage. This allows for faster response to changes in the weight of the counterweight 32 and more rapid adjustment of the tension.
[0047] Optionally, the feeding device also includes a guide rail 33. The bracket 1 includes a first side and a second side disposed opposite to each other along a third direction Y. The guide rail 33 is installed on the first side and extends along the first direction X. The connecting wheel 310 is connected to the second side. One end of the tension roller 30 is provided with a slider 34. A part of the slider 34 is slidably connected to the guide rail 33, and the other part passes through the bracket 1 and is connected to one end of the connecting line 311. The other end of the connecting line 311 is snapped into the counterweight 32.
[0048] like Figure 1 and Figure 5 As shown, the side plate 10 of the bracket 1 includes a first side and a second side disposed opposite to each other along the third direction Y. The guide rail 33 can be installed on the first side by welding, bolts or other means, and the connecting wheel 310 can be installed on the second side. In practical applications, by installing the guide rail 33 and the connecting wheel 310 on different sides of the bracket 1 respectively, the space of the bracket 1 can be reasonably utilized, ensuring that each component has sufficient installation and operation space, and preventing accidental interference between the counterweight 32 and the tensioning roller 30 and other components when adjusting the tension.
[0049] A slider 34 is provided on the tension roller 30. Since the connecting wheel 310 is located on the second side, the corresponding connecting line 311 and counterweight 32 are also located on the second side of the bracket 1. At this time, a portion of the slider 34 needs to be slidably connected to the guide rail 33 on the first side, and the other portion needs to pass through the side plate 10 of the bracket 1, so that one end of the connecting line 311 can be fixedly connected to the slider 34. A corresponding slot is provided on the counterweight 32, and the other end of the connecting line 311 is engaged in the slot, allowing the counterweight 32 to be engaged with the connecting line 311. Under the action of the counterweight 32's gravity, the slider 34 slides along the first direction X on the guide rail 33, thereby allowing the tension roller 30 to move along the first direction X on the side plate 10 of the bracket 1. In practical applications, by sliding the slider 34 on the guide rail 33, when the gravity of the counterweight 32 changes, the slider 34 can quickly respond and adjust the position of the tension roller 30, ensuring the stability and consistency of the tension force.
[0050] Optionally, the bracket 1 is provided with a guide groove 13, which extends along the first direction X and is spaced apart from the guide rail 33 along the second direction Z. The slider 34 includes a first connecting part 340 and a second connecting part 341 arranged at an angle. The first connecting part 340 is slidably connected to the guide rail 33. The second connecting part 341 passes through the guide groove 13 and is fixedly connected to one end of the connecting line 311.
[0051] Specifically, the guide groove 13 penetrates the side plate 10 of the bracket 1 along the third direction Y. The guide groove 13 extends along the first direction X on the side plate 10, and the guide groove 13 and the guide rail 33 are spaced apart along the second direction Z. Specifically, the guide groove 13 can be located above or below the guide rail 33 along the second direction Z. The slider 34 includes a first connecting part 340 and a second connecting part 341. The first connecting part 340 is arranged along the second direction Z, and the second connecting part 341 is arranged along the third direction Y, such that the first connecting part 340 and the second connecting part 341 are arranged at an angle, which can be 90 degrees. The first connecting part 340 is disposed at one end of the tension roller 30 and is slidably connected to the guide rail 33 located on the first side of the side plate 10. The second connecting part 341 passes through the guide groove 13 and is fixedly connected to the connecting line 311 located on the second side of the side plate 10. When the counterweight 32 drives the second connecting part 341 to move along the first direction X in the guide groove 13 via the connecting line 311, the first connecting part 340 drives the tension roller 30 to move along the first direction X on the guide rail 33. In this way, the guide groove 13 can provide guidance for the movement of the second connecting part 341 in the first direction X, which makes the displacement of the tension roller 30 more accurate, reduces the error accumulation caused by the excessive freedom of the slider 34, and further improves the reliability of tension adjustment.
[0052] In some alternative embodiments, the top end of the connecting wheel 310 along the second direction Z is flush with the second connecting portion 341.
[0053] like Figure 2 As shown, the top of the connecting wheel 310 along the second direction Z is flush with the second connecting part 341. In this way, the part of the connecting line 311 between the second connecting part 341 and the top of the connecting wheel 310 is parallel to the first direction X, while the part of the connecting line 311 between the top of the connecting wheel 310 and the counterweight 32 is perpendicular to the second direction Z. This ensures that the tension force is transmitted along the shortest path, reduces unnecessary friction and energy loss, and improves the reliability of tension adjustment.
[0054] Optionally, it also includes at least two driven rollers 4, which are rotatably connected to the support 1, and the at least two driven rollers 4 are respectively disposed on both sides of the tension roller 30 along the second direction Z. The driven rollers 4 are used to wind around the portion of the diaphragm 22.
[0055] Specifically, such as Figures 1-6As shown, the driven roller 4 is rotatably connected to the side plate 10 of the support 1. At least two driven rollers 4 are respectively arranged on both sides of the tension roller 30 along the second direction Z. The diaphragm 22 is fed from the material roll 20 and sequentially wound around one driven roller 4, the tension roller 30, and the other driven roller 4. When the drive member 21 drives the material roll 20 to rotate and feed the material, the driven rollers 4 and the tension roller 30 rotate sequentially to feed the diaphragm 22. The tension force during feeding of the diaphragm 22 is adjusted by moving the tension roller 30 along the first direction X. In practical applications, by setting at least two driven rollers 4, the resistance during feeding of the diaphragm 22 can be reduced.
[0056] It should be noted that the number of driven rollers 4 can be selected according to the actual situation. For example, the number of driven rollers 4 can be 2, 3, 4, etc., and this application embodiment does not make a specific limitation on this.
[0057] In some optional embodiments, the feeding device further includes a cutting component 5, which is fixedly connected to the bracket 1 and disposed adjacent to the tensioning component. The cutting component 5 is used to cut the diaphragm 22.
[0058] Specifically, the support 1 also includes a base plate 11, which is connected to the side plate 10 in the aforementioned embodiment. The base plate 11 is horizontally arranged along the third direction Y. The cutting assembly 5 can be fixedly mounted on the base plate 11 by bolts, clips, etc. The cutting assembly 5 is arranged adjacent to the tensioning assembly. The diaphragm 22 is fed to the cutting assembly 5 through the tensioning assembly. The cutting assembly 5 is used to cut the diaphragm 22. In practical applications, by setting the cutting assembly 5, the diaphragm 22 can be cut to a specific length or shape according to actual production requirements to meet the requirements of subsequent processing or assembly. The cutting assembly 5 can ensure accurate cutting position and avoid errors caused by manual cutting.
[0059] This application embodiment does not specifically limit the structure of the cutting component 5, and can be specifically set according to the actual situation. For example, the cutting component 5 may include, but is not limited to, a cutting platform, a clamping member, a cutting member, and a driving mechanism. The clamping member, the cutting member, and the driving mechanism are disposed on the cutting platform. The cutting platform is used to place the diaphragm 22, the clamping member is used to clamp the diaphragm 22 located on the cutting platform, the cutting member is used to cut the diaphragm 22 on the cutting platform, and the driving mechanism is used to control the operation of the cutting member. In this way, before cutting the material, the diaphragm 22 can be clamped by the clamping member before cutting to prevent misalignment and deformation of the diaphragm 22 during cutting.
[0060] Optionally, it also includes a material pulling assembly 7, which is movably connected to the bracket 1 along the first direction X. The material pulling assembly 7 and the cutting assembly 5 are arranged adjacent to each other along the first direction X. The material pulling assembly 7 is used to drive the diaphragm 22 to move a preset distance along the first direction X.
[0061] Specifically, the material pulling assembly 7 is movably connected to the base plate 11 of the support 1. The material pulling assembly 7 is connected to the diaphragm 22. By moving the material pulling assembly 7 along the first direction X on the support 1, the diaphragm 22 is moved a preset distance on the cutting assembly 5. This preset distance is the preset length that the diaphragm 22 needs to be cut, thereby enabling the cutting assembly 5 to cut the diaphragm 22 to the preset length.
[0062] This application embodiment does not specifically limit the structure of the material pulling assembly 7, and can be specifically set according to the actual situation. For example, the material pulling assembly 7 may include, but is not limited to, a motor screw guide rail drive mechanism and a clamping member. The motor screw guide rail drive mechanism is set on the base plate 11 and connected to the clamping member. The clamping member is used to clamp the diaphragm 22. The motor screw guide rail drive mechanism is used to drive the clamping member to move along the first direction X on the base plate 11. By setting the length parameter of the diaphragm 22, the motor drive screw drives the clamping member to move along the first direction X on the guide rail 33 to achieve fixed-length conveying of the diaphragm 22.
[0063] In practical applications, by setting up the material pulling component 7, the material pulling component 7 can move the diaphragm 22 a preset distance along the first direction X. The length of the diaphragm 22 can be automatically controlled according to the set parameters, ensuring that the position of each cut is accurate and correct, thus improving the cutting accuracy and consistency.
[0064] In some alternative embodiments, a movable component 6 is also included, which is movably connected to the support 1 along a first direction X. The movable component 6 is disposed between the cutting component 5 and the tensioning component, and is used to move the diaphragm 22 of the cutting component 5 to disengage from the cutting component 5.
[0065] like Figures 1-6 As shown, the movable component 6 is movably connected to the base plate 11 of the support 1. The movable component 6 is disposed between the cutting component 5 and the tensioning component. The movable component 6 is used to move the diaphragm 22 on the cutting component 5 a certain distance along the first direction X, so that the end of the diaphragm 22 on the cutting component 5 near the pulling component 7 is a certain distance away from the cutting platform along the first direction X, so that the diaphragm 22 on the cutting component 5 is detached. In this way, when the pulling component 7 needs to clamp the diaphragm 22 on the cutting component 5, the movable component 6 makes the diaphragm 22 detach from the cutting component 5, avoiding the collision between the pulling component 7 and the cutting component 5 when clamping the diaphragm 22, extending the service life of the cutting component 5 and the pulling component 7, and thus extending the service life of the feeding device.
[0066] The embodiments of this application do not specifically limit the structure of the moving component 6, but can be specifically set according to the actual situation. For example, the moving component 6 may include, but is not limited to: a drive motor and a moving part. The drive motor is connected to the base plate 11 and the moving part. The moving part is slidably connected to the base plate 11. The moving part is used to connect the diaphragm 22. The drive motor is used to drive the moving part to move along the first direction X.
[0067] In summary, the feeding device of this application embodiment may include at least the following advantages:
[0068] In this embodiment, a connector 31 connects the tension roller 30 and the counterweight 32. Under the action of the gravity of the counterweight 32, the tension roller 30 moves on the support 1 to adjust the tension of the diaphragm 22. The gravity of the tension roller 30 can be adjusted by adjusting the size or number of the counterweights 32, thereby adjusting the tension of the diaphragm 22 on the tension roller 30. Compared with pneumatic or electric mechanisms, this reduces the cost of the feeding device. Furthermore, since the gravity of the counterweight 32 is stable and reliable, it is not limited by power supply or other conditions, thus improving the reliability of the tensioning assembly in adjusting the tension.
[0069] This application also provides a battery production system, which may specifically include the feeding device of any of the above embodiments.
[0070] It should be noted that in this embodiment, the structure of the feeding device is the same as that of the feeding device in any of the above embodiments, and its beneficial effects are similar, so it will not be described in detail here.
