Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery roller presses, and in particular to a main roller wiping roller device for lithium battery roller presses. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Lithium batteries typically consist of a cell, electrolyte, protective circuitry, and outer casing. The cell includes a positive electrode, a negative electrode, and a separator. The positive and negative electrodes are collectively referred to as pole sheets. To improve the density and thickness consistency of the pole sheet surface material, the pole sheets must be rolled after the coating process. This process is called pole sheet rolling. The pole sheets are rolled using the main rollers of a rolling machine. The main rollers must be cleaned after a certain period of use to prevent damage to the pole sheet surface.

[0004] At present, there is a main roller wiping roller device for lithium battery roller press, which uses the wiping roller device to clean the surface of the main roller and complete the roller surface cleaning work. Although the current main roller wiping roller device of lithium battery roller press can automatically clean the surface of the main roller, the use position of the wiping roller device is fixed, resulting in a fixed contact position between the wiping roller device and the main roller. The surface of the main roller is cleaned only by rotational friction, which affects the cleaning effect of the main roller surface. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a main roller wiping roller device for a lithium battery roller press, which overcomes the defects of the current main roller wiping roller device.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] An embodiment of the present invention provides a main roller wiping roller device for a lithium battery roller press, comprising a base plate, a bracket being provided on the base plate, a cleaning roller being provided above the main roller area inside the bracket, a sleeve being coaxially fixed to the end of the cleaning roller, the sleeve at at least one end of the cleaning roller being circumferentially connected to the output shaft of a rotating drive member fixed on a support member, the rotating drive member being able to drive the sleeve to move, and the sleeve being able to generate relative motion along the axis with the output shaft of the rotating drive member, the support member being installed on the bracket, and the sleeve being connected to a reciprocating linear motion drive mechanism on the support member to drive the cleaning roller to perform reciprocating motion along its axis.

[0008] Optionally, the reciprocating linear motion driving mechanism includes a worm provided on the output shaft of the rotational driving member. The worm meshes with at least one worm wheel. The worm wheel is rotatably connected to the support member. A driving rod that rotates synchronously with the worm wheel is provided at an eccentric position of the worm wheel. The driving rod is embedded in a sliding groove provided in the linear motion member. The linear motion member is slidably connected to the support member along the axis direction of the cleaning roller. The linear motion member is connected to the sleeve through a bearing assembly.

[0009] Optionally, both sides of the worm mesh with the worm wheels, and the worm wheels on both sides of the worm are symmetrically arranged with respect to the worm.

[0010] Optionally, the worm wheel is fixedly connected to a wheel shaft. The wheel shaft is rotatably connected to worm wheel support plates located on both sides of the worm wheel. The worm wheel support plates are fixed to the support member. The outer end of the wheel shaft passes through one side of the worm wheel support plate and is connected to one end of a swing rod. The other end of the swing rod is provided with a driving rod to realize the eccentric setting of the driving rod with respect to the center of the worm wheel.

[0011] Optionally, the bearing assembly includes a bearing. The inner ring of the bearing is fixed to the sleeve, and the outer ring of the bearing is connected to a moving frame. The moving frame is fixedly connected to the linear motion member.

[0012] Optionally, a guiding column is provided on the support member. The guiding column passes through the moving frame and is slidably connected to the moving frame. The guiding column is used to guide the movement of the moving frame.

[0013] Optionally, lifting plates are respectively passed through the sleeves at both ends of the cleaning roller. The sleeves are slidably connected to the lifting plates. The lifting plates are slidably connected to the side of the bracket in the vertical direction. The lifting plates are connected to a lifting mechanism installed on the side of the bracket. The lifting mechanism can drive the cleaning roller to lift to adjust the distance between the cleaning roller and the main roller.

[0014] Optionally, the lifting mechanism includes a lead screw with a vertically arranged axis connected to the lifting plate. The lead screw is rotatably connected to the bracket. The lead screw can rotate around its own axis to make the lifting plate move up and down along the support.

[0015] Optionally, the tops of the lead screws of the lifting mechanisms on both sides of the bracket are connected to a transmission shaft through a bevel gear transmission mechanism. The transmission shaft is rotatably connected to the top of the bracket.

[0016] Optionally, a handle is connected to one end of the transmission shaft;

[0017] Or;

[0018] One end of the transmission shaft is connected to a rotational motion output device fixed to the bracket.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. In the main roller wiping roller device of the present invention, the sleeve at at least one end of the cleaning roller is circumferentially connected to the output shaft of the rotating drive member, and the sleeve is connected to the reciprocating linear motion drive mechanism, so that the sleeve can drive the cleaning roller to rotate around its own axis while the cleaning roller can also make reciprocating linear motion along its own axis. When the cleaning roller cleans the surface of the main roller, it generates a cleaning force along the circumferential direction of the main roller and a cleaning force along the axial direction of the main roller. Compared with the traditional cleaning force that only generates the circumferential direction of the main roller, the cleaning effect is better, and the cleaning effect of the main roller surface is improved.

[0021] 2. In the main roller wiping roller device of the present invention, the rotating driving element utilizes the cooperation of a worm, a worm gear, a driving rod, and a linear motion part to realize the reciprocating motion of the cleaning roller along its own axis. A rotating driving part is adopted, which can output both the rotational motion of the cleaning roller and the reciprocating linear motion of the cleaning roller. The two motions of the cleaning roller can be achieved by using one power device, which reduces the number of power devices used and reduces the cost of the device.

[0022] 3. In the main roller wiping roller device of the present invention, the worm gear drives the linear motion part to perform reciprocating linear motion through the driving rod at the eccentric position. The rotating drive part only needs to output rotational motion in one direction. When the cleaning roller performs high-frequency reciprocating linear motion to improve the cleaning effect, the rotating drive part does not need to perform frequent reversing, which reduces the equipment requirements for the rotating drive part.

[0023] 4. In the main roller wiping roller device of the present invention, the sleeves at both ends of the cleaning roller are connected to the lifting plate, and the lifting plate is connected to the lifting mechanism. The lifting mechanism can drive the cleaning roller to rise and fall, thereby adjusting the distance between the cleaning roller and the main roller, so that the cleaning roller can adjust the distance between the cleaning roller and the main roller according to the cleaning requirements, thereby ensuring the cleaning effect and improving the applicability of the entire cleaning roller device.

[0036] Embodiment 1

[0037] This embodiment provides a main roller cleaning roller device for a lithium battery roller press, as Figure 1 - Figure 2 shown, which includes a base 1. A bracket is fixedly arranged on the upper surface of the base 1. In this embodiment, the base 1 and the bracket can adopt the base 1 and the bracket on the roller press, and there is no need to additionally set corresponding bases and brackets. The bracket includes two bracket plates 2. The bottom ends of the bracket plates 2 are vertically and fixedly connected to the base 1. A top plate 3 is arranged between the top ends of the two bracket plates 2. A main roller area is arranged between the two bracket plates 2. A main roller 4 is arranged in the main roller area. The main roller 4 is used for rolling the battery electrode sheet. The two ends of the main roller 4 are respectively rotationally connected to the two bracket plates 2, and the main roller 4 can rotate around its own axis.

[0038] Above the main roller area, a cleaning roller 5 is provided. The cleaning roller 5 is used to contact the main roller 4 to clean the surface of the main roller 4.

[0039] At both ends of the cleaning roller 5, sleeves 6 are coaxially arranged. The sleeve 6 passes through the lifting plate 7 and the support plate 2, and the sleeve 6 is slidably connected to the lifting plate 7 and the support plate 2. While the sleeve 6 can rotate around its own axis, the sleeve 6 can also move linearly along its own axis direction.

[0040] As Figure 3 shown, the lifting plate 7 is embedded in the lifting groove 8 provided in the support plate 2. The lifting plate 7 is slidably connected to the support plate 2 through the lifting groove 8. The lifting plate 7 can perform vertical lifting movement, thereby driving the cleaning roller 5 to perform vertical lifting movement to adjust the distance between the cleaning roller 5 and the main roller 4.

[0041] Correspondingly, a vertical groove 9 for the sleeve 6 to pass through is opened on the support plate 2 to leave a space for the sleeve 6 to perform vertical lifting movement.

[0042] At least one end of the sleeve 6 is connected to a rotation driving member, and the rotation driving member can drive the sleeve and the cleaning roller 5 to rotate around its own axis.

[0043] In this embodiment, the sleeve 6 on one side of the cleaning roller 5 is connected to the rotation driving member. The rotation driving member adopts a motor 10. The motor 10 is installed on a support member. In this embodiment, the support member adopts a support plate 11. The motor 10 is fixed on the support plate 11, and the support plate 11 is fixedly connected to the lifting plate 7.

[0044] The sleeve 6 is sleeved on the outer periphery of the output shaft 10-1 of the motor 10, and the sleeve 6 is circumferentially connected to the output shaft 10-1 of the motor 10. Specifically, a long protrusion 10-2 arranged along its axis direction is provided on the shaft surface of the output shaft 10-1 of the motor 10. The long protrusion 10-2 is embedded in the long groove provided on the inner cylindrical surface of the sleeve 6. The long protrusion 10-2 is slidably connected to the sleeve 6 through the long groove. Thus, the output shaft 10-1 of the motor 10 can drive the sleeve 6 to rotate around its own axis by using the long protrusion 10-2 and the long groove, and at the same time, the sleeve 6 can also perform reciprocating linear motion along its own axis direction.

[0045] The sleeve 6 is also connected to a reciprocating linear motion driving mechanism 12 provided on the support plate 11, and the reciprocating linear motion driving mechanism 12 can drive the sleeve 6 to perform reciprocating linear motion along its own axis.

[0046] As Figure 4 - Figure 6As shown, the reciprocating linear motion driving mechanism 12 includes a worm 12-1 provided on the output shaft 10-1 of the motor 10. The worm 12-1 meshes with at least one worm wheel 12-2. In this embodiment, one worm wheel 12-2 is meshed on each side of the worm 12-1, and the worm wheels 12-2 on both sides are symmetrically arranged with respect to the axis of the worm 12-1.

[0047] The worm wheel 12-2 is rotatably connected to the fixed frame. The axis of the worm wheel 12-2 is perpendicular to the support plate 11, and the fixed frame is fixed on the support plate 11.

[0048] In this embodiment, the fixed frame adopts a channel structure, including a first plate portion 12-3 and second plate portions 12-4 vertically arranged on both sides of the first plate portion. The worm wheel support plates 12-5 connected to the worm wheels 12-2 on both sides are fixed to the second plate portions 12-4. The sleeve 6 of the cleaning roller 5 passes through the first plate portion 12-3 and is slidably connected to the first plate portion 12-3.

[0049] Specifically, the worm wheel 12-2 is fixedly connected to the wheel shaft. Both ends of the wheel shaft are rotatably connected to the worm wheel support plate 12-5 through bearings. The wheel shaft can rotate around its own axis. The upper end of the wheel shaft passes through the upper worm wheel support plate 12-5 and is connected to one end of a swing rod 12-6. The other end of the swing rod 12-6 is connected to a driving column 12-7. The axis of the driving column 12-7 is parallel to the axis of the worm wheel 12-2. The driving column 12-7 is eccentrically arranged with respect to the center of the worm wheel 12-2 and can rotate synchronously with the worm wheel 12-2 around the center of the worm wheel 12-2.

[0050] The driving column 12-7 extends into a chute provided in the linear motion member. The long axis of the chute is perpendicular to the axis of the sleeve 6.

[0051] The linear motion member is slidably connected to the support plate 11 along the axis direction of the sleeve 6. The linear motion member can perform reciprocating linear motion along the axis direction of the sleeve 6.

[0052] Specifically, the linear motion member adopts a T-shaped rod, including a first rod portion 12-8 perpendicular to the axis of the sleeve 6 and a second rod portion 12-9 vertically fixed in the middle of the first rod portion 12-8. The first rod portion 12-8 is provided with a chute. The second rod portion 12-9 is slidably connected to a guide rail 12-10. The guide rail 12-10 is fixed on the first plate portion 12-3 of the fixed frame, thereby realizing the sliding connection between the linear motion member and the support plate 11.

[0053] An inner end of the second rod portion 12-9 is provided with a connecting rod 12-11. The connecting rod 12-11 is connected to a bearing assembly. The bearing assembly is connected to the sleeve 6. The linear motion member can drive the sleeve 6 to move along its own axis direction through the bearing assembly.

[0054] The bearing assembly includes a bearing 12-12. The inner ring of the bearing 12-12 is sleeved on the outer periphery of the sleeve 6 and fixedly connected to the sleeve 6. The outer ring of the bearing 12-12 is fixedly connected to the moving frame 12-13. The moving frame 12-13 is slidably connected to the support plate 11, and the moving frame 12-13 is fixed to the connecting rod 12-11. The linear motion member can drive the sleeve 6 to perform linear reciprocating motion along its own axis through the moving frame 12-13.

[0055] In this embodiment, the first plate portion 12-3 is provided with a guide post 12-14. The guide post 12-14 passes through the moving frame 12-13 and is slidably connected to the moving frame 12-13. The axis of the guide post 12-14 is parallel to the axis of the sleeve 6. The movement of the moving frame 12-13 is guided by the guide post 12-14. The linear motion accuracy of the sleeve 6 is ensured by the guide post 12-14, and further the linear motion accuracy of the cleaning roller 5 is ensured, preventing uneven cleaning effect of the main roller caused by the deviation of the movement track of the cleaning roller 5.

[0056] The working principle of the reciprocating linear motion driving mechanism in this embodiment is as follows:

[0057] The motor 10 drives the worm 12-1 to rotate. The worm 12-1 drives the worm wheels 12-2 on both sides of it to rotate around their own axes. The worm wheels 12-2 drive the swing rod 12-6 to rotate through the rotating shaft. The swing rod 12-6 drives the driving column 12-7 to move. The driving column 12-7 is matched with the T-shaped rod through the chute. The movement of the driving column 12-7 drives the T-shaped rod to move along the axis direction of the sleeve 6. At the same time, the T-shaped rod drives the moving frame 12-13 to move along the axis direction of the sleeve 6 through the connecting rod 12-11. The moving frame 12-13 drives the sleeve 6 to perform reciprocating linear motion along its own axis through the bearing 12-12. At the same time, the moving frame 12-13 is connected to the sleeve 6 through the bearing 12-12, and the moving frame 12-13 does not affect the rotation of the sleeve 6 around its own axis.

[0058] In this embodiment, the worm wheels 12-2 on both sides of the worm 12-1 and the corresponding linear motion members, guide rails 12-10, moving frames 12-13, guide posts 12-14 and other components are symmetrically arranged with respect to the center of the worm 12-1, so that both sides of the sleeve 6 can receive uniform forces to drive it to perform linear motion, ensuring the linear motion accuracy of the sleeve 6.

[0059] Moreover, the motor 10 uses the cooperation of components such as the worm 12-1, worm wheels 12-2, driving rod 12-7, and linear motion members to realize the reciprocating motion of the cleaning roller 5 along its own axis. By using one motor 10, it can not only provide power for the rotation of the sleeve 6, but also provide power for the reciprocating linear motion of the sleeve 6. Only one power device is required for the two motions of the cleaning roller 5, reducing the number of power devices used and lowering the cost of the device.

[0060] In addition, the worm gear 12-2 drives the linear motion part to perform reciprocating linear motion through the driving rod 12-7 at the eccentric position. The motor 10 only needs to output rotational motion in one direction, and there is no need to use a bidirectional rotation motor. Moreover, compared with the solution using a bidirectional rotation motor, when the cleaning roller 5 performs high-frequency reciprocating linear motion to improve the cleaning effect, it avoids frequent commutation of the bidirectional rotation motor, reduces the equipment requirements for the motor, extends the service life of the motor, enables the cleaning roller 5 to perform reciprocating motion at a higher frequency, and improves the cleaning effect on the main roller 4.

[0061] In this embodiment, the lifting plates 7 slidably connected to the two support plates 2 are both connected to the lifting mechanism provided on the support plates 2.

[0062] As Figure 7 shown, the lifting mechanism adopts a lead screw lifting mechanism, including a lead screw 13 with a vertical axis. The lead screw 13 is connected to the lifting plate 7, and the lifting plate 7 is vertically slidably connected to the support plate 2 through a lifting groove 8. The rotation of the lead screw 13 can drive the lifting plate 7 to perform vertical lifting motion along the support plate 2.

[0063] The top end of the lead screw 13 is rotationally connected to the top plate 3 through a bearing, and the lead screw 13 can rotate around its own axis.

[0064] Furthermore, in order to ensure the synchronization of the lifting of the two lifting plates, the top ends of the lead screws 13 of the two lifting mechanisms are connected to the transmission shaft 15 through a bevel gear transmission mechanism 14. The transmission shaft 15 is rotationally connected to the top plate 3. Through the transmission shaft 15, the power can be transmitted between the two lead screws 13, enabling the two lead screws 13 to rotate synchronously around their own axes, ensuring that the heights of the two lifting plates 7 always remain the same. At the same time, by adjusting the height of the lifting plate 7 through the lead screw 13, precise height adjustment can be achieved.

[0065] Specifically, the two ends of the transmission shaft 15 are provided with first bevel gears, and the first bevel gears are meshed with the second bevel gears provided at the top of the lead screws 13. When the transmission shaft 15 rotates, it can drive the two lead screws 13 to rotate synchronously through the first bevel gears and the second bevel gears.

[0066] One end of the transmission shaft 15 is connected to the handle 16, and the staff can drive the transmission shaft 15 to rotate through the handle 16. In another embodiment, the transmission shaft 15 is connected to a rotational motion output device fixed on the outer side of the support plate 2. The rotational motion output device adopts a motor, and the output shaft of the motor is connected through a transmission mechanism. The transmission mechanism adopts a chain transmission mechanism or a belt transmission mechanism, etc., which can be set by those skilled in the art according to actual needs.

[0067] In this embodiment, the lifting plate 7 can drive the cleaning roller 5 to lift, so as to adjust the distance between the cleaning roller 5 and the main roller 4, so that the cleaning roller 5 can adjust the distance from the main roller 4 according to the cleaning requirements, ensure the cleaning effect, and improve the applicability of the entire cleaning roller device.

[0068] The working method of the wiping roller device in this embodiment is as follows:

[0069] The staff rotates the transmission shaft through the handle 16. The transmission shaft 15 drives the lead screws 13 on both sides to rotate by means of the bevel gear transmission mechanisms 14 at both ends. The rotation of the lead screws 13 drives the lifting plate 7 to descend. The lifting plate 7 drives the through sleeve 6 and the cleaning roller 5 to move downward until the cleaning roller 5 contacts the surface of the main roller 4. The distance between the cleaning roller 5 and the main roller 4 is adjusted according to the cleaning requirements of the main roller 4, so as to adjust the contact strength between the cleaning roller 5 and the main roller 4. Then, the motor 10 is started. The output shaft 10-1 of the motor 10 rotates. The output shaft 10-1 of the motor 10 drives the cleaning roller 5 to rotate around its own axis through the sleeve 6, and the rotation direction is the same as that of the main roller 4 to clean the surface of the main roller 4. At the same time, the worm 12-1 on the output shaft of the motor 10 rotates, driving the worm gear 12-2 to rotate, thereby driving the T-shaped rod to perform a reciprocating linear motion along the axis of the sleeve 6. The T-shaped rod drives the sleeve 6 to perform a reciprocating linear motion along its own axis through the moving frame 12-13 and the bearing 12-12, so as to facilitate the cleaning roller 5 to evenly clean the surface of the main roller 4, improve the working effect of the cleaning roller 5, and avoid cleaning dead corners on the surface of the main roller.

[0070] Embodiment 2

[0071] This embodiment provides a main roller wiping device for a lithium battery rolling press. Compared with Embodiment 1, the difference lies in that the second plate portion 12-4 and the first plate portion 12-3 of the fixing frame are arranged in a split manner. Preferably, the first plate portion 12-3 and the second plate portion 12-4 are connected by a plug-in structure. The first plate portion 12-3 is fixedly connected to the support plate 11, and the second plate portion 12-4 is not connected to the support plate 11. The second plate portion 12-4 is provided with a plug, and the first plate portion 12-3 is provided with a slot. The second plate portion 12-4 is plugged and connected to the first plate portion 12-3 through the plug and the slot. The second plate portion 12-4 can move away from or towards the first plate portion. Correspondingly, the moving frame 12-13 also adopts a split structure, including a middle part and side parts plugged and fixed on both sides of the middle part through plugs and slots. The side parts are connected to the second rod portion through a connecting rod 12-11. The middle part is fixedly connected to the outer ring of the bearing 12-12. The side parts are slidably connected to the guide post 12-14. The cross section of the guide post 12-14 is rectangular or square. The guide post 12-14 is fixed to the inner side surface of the second plate portion 12-4 through a guide post fixing seat. The guide rail 12-10 slidably connected to the second rod portion 12-9 of the T-shaped rod is also fixed to the inner side surface of the second plate portion 12-4 through a guide rail fixing seat.

[0072] When the side part is plugged and connected to the middle part through the plug and the slot, the middle part can move linearly with the side part. When the side part is separated from the middle part, the middle part cannot move with the side part.

[0073] Two telescopic driving members are provided on the bottom surface of the support plate 11. The telescopic driving members adopt cylinders. The cylinder body of the cylinder is fixed on the bottom surface of the support plate 11. The piston rod of one cylinder is connected to the second plate portion 12-4 on one side through a connecting plate, and the piston rod of the other cylinder is connected to the second plate portion 12-4 on the other side through a connecting plate.

[0074] Through the cylinders, the second plate portions 12-4 on both sides can be driven to move towards or away from the first plate portion 12-3. When the second plate portion 12-4 is separated from the first plate portion 12-3, the side part of the moving frame 12-13 is also separated from the middle part. At this time, the worm gear 12-2 is disengaged from the worm 12-1, and the sleeve 6 cannot perform linear motion along its axis. At this time, when the motor 10 works, the sleeve 6 can only rotate around its own axis, so that the cleaning roller 5 can only rotate around its own axis.

[0075] When adopting this setting method, after the relative positions of the cleaning roller 5 and the main roller 4 along the axis are determined, the worm gear 12-2 and the worm 12-1 are disengaged. At this time, the sleeve 6 cannot move along its axis under the action of the strip-shaped protrusion 10-2 of the output shaft 10-1 of the motor 10 and the friction force of the sleeve 6, and the cleaning roller 5 can continuously clean the set part of the main roller 4.

[0076] Therefore, the main roller cleaning roller device of this embodiment can not only enable the cleaning roller to perform reciprocating linear motion to clean the main roller, but also enable the cleaning roller to stay at a set position along the axis to focus on cleaning a set position of the main roller, ensuring the cleaning effect of the main roller.

[0077] When only a local position of the main roller needs to be cleaned, the cleaning roller can be stopped at a set position along the axis for continuous cleaning, saving the time for the reciprocating motion of the cleaning roller. At the same time, it also avoids the frictional damage to the parts of the main roller that do not need to be cleaned.

[0078] The remaining structures of this embodiment are the same as those of Embodiment 1 and will not be repeated here.

[0079] Embodiment 3

[0080] This embodiment provides a main roller cleaning roller device for a lithium battery roller press. Compared with Embodiment 1, the entire cleaning roller device further includes a photoelectric distance measuring sensor. The photoelectric distance measuring sensor can use existing equipment and includes a transmitting end and a receiving end. The transmitting end is arranged in a groove provided on the bottom surface of the lifting plate, and the receiving end is arranged in a groove provided on the bottom surface of the lifting chute. The lifting distance of the lifting plate can be detected through the photoelectric distance measuring sensor, so as to facilitate the staff to control the distance between the main roller and the cleaning roller, avoiding the frictional damage to the surface of the main roller caused by excessive direct contact force between the cleaning roller and the main roller while ensuring the cleaning effect.

[0081] The remaining structures of this embodiment are the same as those of Embodiment 1 and will not be repeated here.

[0082] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application.
