Material belt conveying device and lithium battery production equipment

Abstract

The utility model relates to a material belt conveying device and lithium battery production equipment. The material belt conveying device comprises a mounting frame, a passing roller, an adjusting assembly and a rotating joint. When the tension of the material belt wound around the passing roller is not uniform, the acting force applied to the passing roller by the material belt is different in the lengthwise direction of the passing roller, namely in the width direction of the material belt, and the passing roller is forced to swing relative to the mounting frame until the stress of the passing roller is balanced again, so that the tension in the width direction of the material belt is balanced. In the continuous change process of the tension, the passing roller can be dynamically adjusted under the action of the restoring force of the adjusting assembly, so that the passing roller is kept in contact with all positions of the material belt in the width direction, and the stress of the passing roller is dynamically balanced. Therefore, the passing roller can adaptively adjust the angle according to the tension change of the material belt, so that the tension distribution of the material belt wound around the passing roller in the width direction is always kept uniform, and the material belt can be effectively prevented from wrinkling.

[0031] Please refer to Figure 1 The present application provides a kind of material belt conveying device 10. In addition, the present application also provides a kind of lithium battery production equipment (not shown in figure), which includes the above-mentioned material belt conveying device 10.

[0032] The lithium battery production equipment can be a winding machine, a die-cutting device, or a cutting and stacking integrated machine, etc. The tape conveying device 10 is used to convey a tab tape or a diaphragm tape, etc. and can make the tension distribution of the tape more uniform in the width direction after the tape passes through the tape conveying device 10, thereby effectively avoiding the generation of wrinkles in the tape, and further improving the quality of the finally prepared battery cell.

[0033] For the winding machine, it generally includes the above-mentioned tape conveying device 10 and a winding needle mechanism. The tab tape and the diaphragm tape can be guided and transitioned by the tape conveying device 10 respectively and then enter the winding needle mechanism for winding, so as to effectively avoid the tab tape and the diaphragm tape from being raised or misaligned due to wrinkles, thereby helping to improve the quality of the winding prepared battery cell.

[0034] For the cutting and stacking integrated machine, it generally includes the above-mentioned tape conveying device 10 and a cutting device. The tab tape is guided and transitioned by the tape conveying device 10 and then enters the cutting device for slicing. The cutting device can cut the tab tape into a plurality of tabs in sequence. Since the tape conveying device 10 can effectively prevent the tab tape from wrinkling, the cutting device can reduce the size error when slicing the tab tape. Moreover, the diaphragm tape required for stacking can also be guided and transitioned by the tape conveying device 10 and then enter the stacking station, thereby ensuring the surface flatness of the diaphragm tape, and further avoiding the battery cell from wrinkling after stacking. It can be seen that the cutting and stacking integrated machine provided with the tape conveying device 10 can also improve the quality of the stacked prepared battery cell.

[0035] Please refer to Figure 2 and Figure 3 , the tape conveying device 10 in an embodiment of the utility model includes mounting frame 100, over roller 200, adjustment assembly 300 and rotary joint 400.

[0036] The mounting frame 100 is used to provide support for the over roller 200 and the adjustment assembly 300. The two ends of the over roller 200 are connected with the two adjustment assemblies 300 through the rotary joints 400 respectively. Specifically, the two adjustment assemblies 300 are generally arranged on the mounting frame 100 along the first direction, and the over roller 200 is located between the two adjustment assemblies 300. More specifically, the mounting frame 100 includes two supporting plates 110 arranged oppositely along the first direction, and the over roller 200 is located between the two supporting plates 110. The two adjustment assemblies 300 are mounted on the two supporting plates 110 respectively. The first direction refers to the left-right direction as shown in Figure 2 and Figure 3 In the actual application scenario of the tape conveying device 10, the first direction is usually the horizontal direction.

[0037] The material belt passing through the material belt conveying device 10 can pass around the passing roller 200 and drive the passing roller 200 to rotate. Specifically, the passing roller 200 can rotate around the first rotation axis. Specifically, in the embodiment, the passing roller 200 includes a roller body 210 and a roller shaft 220, the roller shaft 220 is coaxially arranged with the first rotation axis, and the roller body 210 is rotatably sleeved on the roller shaft 220. The roller body 210 and the roller shaft 220 can be connected by a bearing to enable the roller body 210 to rotate around the roller shaft 220.

[0038] Since the roller shaft 220 does not need to rotate, it can be directly connected with the rotary joint 400 to simplify the connection structure, and the material belt passing around the passing roller 200 can drive the roller body 210 to rotate around the roller shaft 220. It should be noted that in other embodiments, the roller body 210 and the roller shaft 220 can be fixedly connected, and the roller shaft 220 can be indirectly connected with the rotary joint 400 through a rotating element such as a bearing, so that the passing roller 200 as a whole can rotate around the first rotation axis.

[0039] It should be noted that when the material belt conveying device 10 is in an initial state, the first rotation axis of the passing roller 200 extends substantially in the first direction. The above-mentioned initial state refers to the state when the material belt conveying device 10 is not started to work and the material belt has not yet passed around the passing roller 200.

[0040] Please refer again to Figures 1 to 3 Each adjusting assembly 300 includes an elastic member 320 and a guide member 330, and the two guide members 330 are connected with the two ends of the passing roller 200 through the two rotary joints 400 respectively. The elastic member 320 is connected with the guide member 330 and can exert an elastic force on the guide member 330, which in turn acts on the passing roller 200 through the guide member 330 and the rotary joint 400, thereby exerting a restoring force on the two ends of the passing roller 200.

[0041] The guide member 330 can reciprocate in the first direction. Moreover, the guide member 330 has a tendency to move away from the passing roller 200 under the action of the elastic force provided by the elastic member 320, so that the guide member 330 can exert a pulling force on the passing roller 200 through the rotary joint 400. When the passing roller 200 deviates from the initial state, the passing roller 200 also has a tendency to return to the initial state under the action of the elastic member 320.

[0042] In the embodiment, the guide member 330 includes a guide shaft, and one end of the guide shaft is connected with the rotary joint 400.

[0043] Specifically, a shaft sleeve can be embedded on the support plate 110, and the guide shaft is slidably mounted on the support plate 110 through the shaft sleeve. Specifically, the guide shaft can slide relative to the support plate 110 in the first direction, that is, the guide members 330 located at the two ends of the passing roller 200 can move closer or farther away in the first direction.

[0044] It should be noted that in other embodiments, a guide rail extending in the first direction can also be provided, and a sliding block can also be provided on the guide rail, and the sliding block can also constitute the guide 330.

[0045] More specifically, in the embodiment, the elastic member 320 is provided as a compression spring, the guide shaft has a limiting member 331 at the end away from the rotary joint, and the compression spring is sleeved on the guide shaft. The elastic force generated by the compression spring acts on the guide shaft through the limiting member 321, and then acts on the roller 200 through the rotary joint 400. Moreover, the compression spring is sleeved on the guide shaft and is not easy to fall off, and the compression direction can be well limited by the guide shaft, thereby ensuring the reliability of the elastic member 320.

[0046] In addition, the elastic member 320 can also be provided as any one or a combination of elastic sheets, tension springs, elastic ropes, etc. The elastic member 320 can provide an elastic force, and its form is not limited, and the connection mode of the elastic member 320 in different forms can be adjusted accordingly. For example, when the elastic member 320 is provided as an elastic sheet, it is clamped on the side of the limiting member 321 away from the roller 200 and the back plate 110; when the elastic member 320 is provided as an elastic rope, one end thereof can be fixed to the mounting frame 100, and the other end can be connected to the end of the guide shaft away from the rotary joint 300.

[0047] Further, in the embodiment, the guide 330 includes at least two guide shafts parallel to each other, and the adjusting assembly 300 is provided with a connecting block 340, each guide shaft is connected to the connecting block 340, and the connecting block 340 is connected to the rotary joint 400. The structure formed by the at least two guide shafts parallel to each other and the connecting block 340 has higher stability, and the stability of the guide 330 during sliding can be improved.

[0048] The rotary joint 400 allows the roller 200 to rotate relative to the guide 320, so that the first rotation axis of the roller 200 swings in a swing plane, and the swing plane is a virtual plane in which the first rotation axis is located. That is, the roller 200 is not fixed relative to the mounting frame 100, but can float in one degree of freedom. In the working process of the material belt conveying device 10, the roller 200 will be affected by the material belt, thereby generating a floating state relative to the initial state. During the floating of the roller 200, the rotary joint 400 will be displaced or deflected, thereby driving the guide 320 to slide relative to the mounting frame 100.

[0049] Please refer to Figure 4 and Figure 5 In one embodiment, the rotary joint 400 includes a first rotation shaft 410 and a second rotation shaft 420, the first rotation shaft 410 is connected to one end of the roller 200, the second rotation shaft 420 is connected to the guide 330, and the guide 330 is slidably mounted on the mounting frame 100.

[0050] In the embodiment, the roller shaft 220 is rotatably connected with the rotary joint 400 through the first rotating shaft 410, and the guide 330 is rotatably connected with the rotary joint 400 through the second rotating shaft 420. The roller 200 and the guide 330 can rotate around the first rotating shaft 410 and the second rotating shaft 420 respectively, and cooperate with the extension and retraction of the guide 330, so that the roller 200 can swing. Moreover, in the swinging process of the roller 200, the guide 330 does not deflect with the roller 200, so the adjusting assembly 300 can always maintain stable position.

[0051] The first rotating shaft 410 and the second rotating shaft 420 extend in a direction substantially perpendicular to the first rotation axis, so the first rotating shaft 410 and the second rotating shaft 420 can better limit the swinging direction of the roller 200, so that the swinging plane is perpendicular to the first rotating shaft 410 and the second rotating shaft 420. That is, the first rotation axis always maintains in a plane, thereby improving the stability in the swinging process of the roller 200.

[0052] Further, in the embodiment, the rotary joint 400 further comprises a connecting body 430, the first rotating shaft 410 and the second rotating shaft 420 are installed on the connecting body 430, one end of the roller 200 is rotatably installed on the connecting body 430 through the first rotating shaft 410, and the guide 330 is rotatably installed on the connecting body 430 through the second rotating shaft 420.

[0053] Specifically, the connecting body 430 can adopt two interval arranged cover plates (not marked in the figure), and the first rotating shaft 410 and the second rotating shaft 420 are both fixed between the two cover plates. The connecting body 430 can facilitate the installation of the first rotating shaft 410 and the second rotating shaft 420. The guide 330 and the roller shaft 220 can extend into the two cover plates and be connected with the second rotating shaft 420 and the first rotating shaft 410 respectively, so as to further limit the degrees of freedom of the guide 330 and the roller shaft 220.

[0054] It should be noted that in other embodiments, the rotary joint 330 can also adopt other structures, such as universal joint, spherical pair, etc.

[0055] In addition, please refer to Figure 6 In another embodiment, each adjusting assembly 300 further comprises a supporting body 310, and the guide 330 is slidably installed on the supporting body 310. The rotary joint 400 comprises a third rotating shaft (not shown in the figure), the third rotating shaft is connected with one end of the roller 200, the adjusting assembly 300 further comprises a rotating connecting piece 350, the rotating connecting piece 350 comprises a fourth rotating shaft (not shown in the figure), and the supporting body 310 is rotatably installed on the mounting rack 100 through the fourth rotating shaft.

[0056] The passing roller 200 is capable of rotating around the third rotation axis, and the supporting body 310 is capable of rotating around the fourth rotation axis relative to the mounting frame 100, and cooperating with the guide 330 to extend and retract, so that the passing roller 200 can realize swinging. The rotating connecting piece 350 can adopt a universal joint, a spherical pair or the like structure, or can be provided as a pin shaft only. The difference from the previous embodiment is that the position of the adjusting assembly 300 is not fixed, but will be offset with the swinging of the passing roller 200. Moreover, the third rotation axis and the fourth rotation axis also extend in a direction substantially perpendicular to the first rotation axis, so that the third rotation axis and the fourth rotation axis can better limit the swinging direction of the passing roller 200, so that the above-mentioned swinging plane is perpendicular to the third rotation axis and the fourth rotation axis.

[0057] Under different working conditions, the passing roller 200 can be balanced under the restoring force of the adjusting assembly 300. Please refer to Figure 7 , the force conditions of the passing roller 200 under different working conditions are as follows:

[0058] As shown in Figure 7 (a), when the passing roller 200 is in the initial state, the material belt does not pass through the passing roller 200, so that the resultant force of the passing roller 200 in the direction perpendicular to the first rotation axis is equal to 0; and in the direction parallel to the first rotation axis, i.e. the axial direction of the passing roller 200, the restoring forces provided by the left and right adjusting assemblies 300 are the same in size and opposite in direction, i.e. FS1=FS2, and the resultant force is also equal to 0. Moreover, the direction of the restoring force is consistent with the extension direction of the first rotation axis, so that the component of FS1 and FS2 in the direction perpendicular to the first rotation axis is 0, and the passing roller 200 remains balanced.

[0059] As shown in Figure 7 (b), when the material belt passes through the passing roller 200, the passing roller 200 will tension the material belt, and the material belt will exert a force on the passing roller 200 perpendicular to the first rotation axis, thereby driving the passing roller 200 to be displaced compared with the initial position. The directions of the restoring forces provided by the left and right adjusting assemblies 300 form angles with the first rotation axis of the passing roller 200, which are θ and θ', respectively. At this time, if the tension of the material belt is uniformly distributed along the width direction (i.e. the extension direction of the first rotation axis), then the above-mentioned force is equal to the resultant force of the components of the restoring forces provided by the two adjusting assemblies 300 in the direction perpendicular to the first rotation axis, i.e. sinθ.FS1+sinθ'.FS2=F.

[0060] As shown in Figure 7 (c), when the tension of the material belt is not uniformly distributed along the width direction, it will cause the force exerted by the material belt on the passing roller 200 to be different in the longitudinal direction of the passing roller 200, i.e. the width direction of the material belt. At this time, the force balance of the passing roller 200 is broken, thereby forcing the passing roller 200 to swing relative to the mounting frame 100 until it switches to Figure 7In the state shown in (d), the force acting on the over roller 200 reaches balance again. After the force acting on the over roller 200 reaches balance again, it indicates that the force applied by the material belt on the over roller 200 is consistent in the width direction of the material belt, and thus the tension distribution of the material belt will also become uniform along the width direction.

[0061] In the process of the tension of the material belt changing constantly, the restoring force applied to the over roller 200 can enable the over roller 200 to achieve dynamic adjustment, so as to maintain contact with each part of the width direction of the material belt and enable the force acting on the over roller 200 to reach dynamic balance. That is, the over roller 200 can adaptively adjust the angle of the first rotation axis according to the change of the tension of the material belt, so as to maintain the tension distribution of the material belt after passing through the over roller 200 uniform in the width direction, and thus effectively prevent the material belt from being wrinkled.

[0062] According to the above force analysis, when the tension of the material belt is 0, both θ and θ' are equal to 0°, and when the tension is greater than 0, the force acting on the over roller 200 is necessarily greater than 0, and thus both θ and θ' are necessarily not equal to 0°. That is, as long as the over roller 200 is subjected to the force of the material belt, it will swing, and the specific size of the restoring force FS1 and FS2 is irrelevant. Therefore, there is no requirement for the size of the restoring force provided by the adjusting assembly 300, and thus a resilient member 320 with smaller elastic force can be selected, so as to improve the response speed of the swing of the over roller 200.

[0063] In the related art, in order to solve the problem of uneven tension distribution in the width direction of the material belt, an elastic pre-tightening member such as a pneumatic cylinder or a compression spring is generally arranged at both ends of the swing roller. The elastic pre-tightening member applies an elastic thrust to the swing roller in a direction substantially perpendicular to the axis of the swing roller, so that the swing roller can achieve up and down floating, thereby allowing the angle of the swing roller to be adaptively adjusted according to the change of the tension when the tension of the material belt fluctuates.

[0064] In order to avoid the elastic pre-tightening member being excessively compressed and losing elasticity, a resilient member with larger elastic force, i.e., larger elastic modulus, is generally required. However, the fluctuation of the tension of the material belt is generally relatively small, and thus the fluctuation of the tension of the material belt may not be sufficient to overcome the elastic force of the elastic pre-tightening member, so that the swing roller cannot timely achieve floating, and thus cannot play a role in real-time adjustment of the tension of the material belt. The present application optimizes the force acting on the over roller 200 by arranging the adjusting assembly 300, so that the elastic force provided by the resilient member 320 is small enough for the over roller 200 to smoothly float, and the size of the elasticity of the resilient member 320 does not need to be considered. The present application is to overcome the defects in the above related art.

[0065] In addition, please refer again to Figure 1 and Figure 2In the embodiment, the material strip conveying device 10 further comprises a support 500 and an adjusting mechanism 600. The adjusting mechanism 600 comprises a rotating shaft 610 rotatably mounted on the support 500, and the mounting frame 100 is fixedly connected to the rotating shaft 610.

[0066] Specifically, the rotating shaft 610 is capable of rotating around a second rotation axis. When the material strip conveying device 10 is in the initial state, the second rotation axis is parallel to the first rotation axis. When the adjusting mechanism 600 drives the mounting frame 100 to rotate through the rotating shaft 610, the roller 200 and the supporting mechanism 300 as a whole are driven to rotate around the second rotation axis, so as to change the angle of the swing plane. In actual use, the swing plane can be adjusted to be parallel to the horizontal plane by precisely controlling the rotation angle of the rotating shaft 610. In this way, the roller 200 will float in the horizontal plane during the working process, so that the influence of the gravity of the parts can be basically ignored.

[0067] Further, in the embodiment, the adjusting mechanism 600 further comprises a limiting plate 620 and a limiting pin 630. The limiting plate 620 is arranged at least one end of the rotating shaft 610, and the limiting plate 620 is provided with a plurality of circumferentially distributed positioning holes (not shown in the figure). The limiting pin 630 is telescopically mounted on the support 500 and directed to the limiting plate 620.

[0068] By operating the limiting pin 630 to be telescopically inserted into or withdrawn from the corresponding positioning hole, the limiting plate 620 can be locked or unlocked on the support 500. Specifically, the rotating shaft 610 can be mounted on the support 500 through a bearing, and the rotating shaft 610 can be manually rotated around its own axis (the second rotation axis) to drive the mounting frame 100 to rotate. With the rotating shaft 610 driving the limiting plate 620 to rotate, the limiting pin 630 can be operated to be inserted into any positioning hole to fix the limiting plate 620 on the support 500. When it is necessary to adjust the angle of the swing plane, the limiting pin 630 is first pulled out of the current positioning hole, and then the limiting pin 630 is inserted into the opposite positioning hole after the rotating shaft 610 is rotated by the required angle.

[0069] More specifically, the adjusting mechanism 600 generally further comprises a potentiometer 640 mounted on the rotating shaft 610. The potentiometer 640 can record the angle of deflection of the rotating shaft 610 relative to the initial position, so as to facilitate the precise control of the rotation angle of the rotating shaft 610.

[0070] The material belt conveying device 10 and the lithium battery production equipment, when the material belt passing through the roller 200 has uneven tension, the force applied by the material belt to the roller 200 will be different in the longitudinal direction of the roller 200, i.e. the width direction of the material belt, and the roller 200 will swing relative to the mounting frame 100 until the force on the roller 200 is balanced again, thereby balancing the tension in the width direction of the material belt. During the continuous change of the tension, the roller 200 can be dynamically adjusted under the restoring force of the adjusting assembly 300, thereby maintaining contact with each part of the width direction of the material belt and achieving dynamic balance of the force on the roller 200. It can be seen that the roller 200 can adaptively adjust the angle of the first rotation axis according to the change of the tension of the material belt, thereby maintaining the uniform tension distribution of the material belt passing through the roller 200 in the width direction, and effectively preventing the material belt from wrinkling.

[0071] The technical features of the above-described embodiments can be combined in any manner.
