Rolling shaping equipment for manufacturing composite current collector with anti-bias effect

Abstract

The present invention discloses a rolling shaping device for manufacturing a composite current collector with an anti-bias effect. The present invention relates to the technical field of rolling shaping. In the process of converting a metal plate into a metal foil plate through rolling, the metal plate in the rolling deformation process expands due to its own deformation, causing the center of the plate to deviate from the rolling center position. Therefore, through the rotational connection of the cross shaft and the slot shaft, there is a certain degree of deflection distance in the vertical direction of the plate movement, so that when the plate is tilted due to the shaping pressure during the rolling shaping process, the tilt angle is transmitted to the fixed ring and the cross shaft through the rubber ring, causing it to deflect accordingly. After the fixed ring and the cross shaft are deflected, the elastic cover is compressed to deform, causing it to generate a reaction force to limit the deflection of the fixed ring of the cross shaft. When the composite current collector plate has a tendency to deviate, a force is generated synchronously to limit its deflection, thereby ensuring the position of the plate during the rolling shaping process.

Description

Technical Field

[0001] The present invention relates to the technical field of roller forming, and in particular to a roller forming device for manufacturing a composite current collector with an anti-bias effect. Background Art

[0002] At present, the composite current collector is a battery material with a "sandwich" structure. The current collector is one of the indispensable components of lithium-ion batteries. It can not only carry active substances, but also collect and output the current generated by the electrode active substances, which is beneficial to reduce the internal resistance of lithium-ion batteries and improve the coulombic efficiency, cycle stability and rate performance of the battery. The positive electrode of the current collector uses aluminum foil and the negative electrode uses copper foil.

[0003] In the process of rolling a metal sheet into a metal foil sheet, the center of the sheet deviates from the center of the rolling because the metal sheet expands due to its own deformation during the rolling deformation process. Summary of the invention

Through the arc surface at the bottom of the arc panel, during the roller shaping process, due to the deformation of the plate, the side of the plate close to the guide plate is deformed and bent. At this time, the concave arc surface at the bottom of the guide plate away from the pressure roller provides a certain range for the deformation and bending of the plate, so that the plate can be smoothly shaped. At the same time, the arc panel restricts the plate to avoid wrinkles after shaping due to deformation and bending. The bottom of the arc panel is an arc surface, and the side of the bottom of the arc panel close to the pressure roller is convex downward, and the side of the bottom of the arc panel away from the pressure roller is concave upward.

[0013] The present invention provides a roller-pressing shaping device for manufacturing a composite current collector with an anti-bias effect. It has the following beneficial effects:

[0014] 1. The roller forming equipment for manufacturing the composite current collector with anti-deflection effect is connected by the shaft groove of the cross shaft and the groove shaft, and has a certain degree of deflection distance in the vertical direction of the plate movement. When the plate is tilted due to the shaping pressure during the roller forming process, the tilt angle is transmitted to the fixed ring and the cross shaft through the rubber ring, causing it to deflect accordingly. After the fixed ring and the cross shaft are deflected, the elastic cover is compressed to deform, causing it to generate a reaction force to limit the deflection of the fixed ring of the cross shaft. When the composite current collector plate tends to deviate, a force is generated synchronously to limit its deflection, thereby ensuring the position of the plate during the roller forming process.

[0015] 2. The roller-pressing shaping equipment for manufacturing the composite current collector with anti-bias effect, through the rubber deformation characteristics of the rubber ring, will decompress the rubber ring upward when the plate passes through, causing deformation at the contact position with the composite current collector plate, thereby increasing the contact area with the plate to prevent the plate from being driven to slide during shaping. At the same time, it cooperates with the cross shaft and elastic cover to limit the position of the plate to prevent the plate from shifting.

[0016] 3. The roller-forming equipment for manufacturing composite current collectors with anti-bias effect uses the arc surface at the bottom of the arc panel. During the roller-forming process, due to the deformation of the plate, the side of the plate close to the guide plate is deformed and bent. At this time, the concave arc surface at the bottom of the guide plate away from the pressure roller provides a certain range for the deformation and bending of the plate, so that the plate can be smoothly shaped. At the same time, the arc panel restricts the plate to avoid wrinkles after shaping due to deformation and bending during the shaping process.

[0017] 4. The roller-pressing shaping equipment for manufacturing composite current collectors with anti-bias effect ensures that the direction of the limiting plate pressing the sliding roller always remains parallel through the cooperation of the limiting plate and the connecting column, so that the deformation degree of the spring is consistent, thereby preventing the sliding roller from tilting in the shaping pressure direction due to the unevenness of the plate during the shaping process, resulting in uneven thickness of the plate after shaping.

DETAILED DESCRIPTION

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0029] The first embodiment, as Figures 1 to 4 As shown, the present invention provides a technical solution: a roller-pressing shaping device for manufacturing a composite current collector with an anti-bias effect, comprising:

[0030] A frame 1 having a frame supporting the mechanism assembly, and a motor 5 is fixedly mounted on the outer side of the frame 1, and a transmission assembly 6 is mounted on the output end of the motor 5;

[0031] An anti-deviation mechanism 2, which is used to limit the composite current collector that has a tendency to deviate during the rolling shaping process, and the anti-deviation mechanism 2 is installed on the top of the frame 1;

[0032] A rolling mechanism 4, which is used to roll and shape the composite current collector, and the rolling mechanism 4 is installed on the top of the frame 1, and the rolling mechanism 4 is connected to the output end of the motor 5 through the transmission assembly 6;

[0033] A material guiding mechanism 3, which is used to guide the composite current collector from the anti-deviation mechanism 2 to the rolling mechanism 4, and the material guiding mechanism 3 is installed on the top of the frame 1, and the material guiding mechanism 3 is located between the anti-deviation mechanism 2 and the rolling mechanism 4;

[0034] The anti-deviation mechanism 2 includes a side plate 201, which is symmetrically mounted on the top of the frame 1, and a groove shaft 203 is symmetrically mounted between the side plates 201, and the two ends of the outer side of the groove shaft 203 are rotatably connected to the inner wall of the side plate 201, and the outer side of the groove shaft 203 is symmetrically provided with an axis groove, and a cross shaft 205 is rotatably mounted at the axis groove of the groove shaft 203, and a fixed wheel 210 is fixedly mounted on the outer side of the cross shaft 205, and a fixed ring 207 is fixedly mounted on the outer side of the groove shaft 203. When the plate is in the process of roller shaping, the moving direction is offset due to the uneven thickness of the plate. When the deflection trend occurs, the offset force is transmitted to the rubber ring 208 and the rotating wheel 209 through the composite current collector plate. After receiving the deflection force, it is transmitted to the fixed ring 207 and the cross shaft 205 through the rotating wheel 209, so that the cross shaft 205 tends to tilt in the shaft groove of the slot shaft 203, so that the elastic cover 206 limits the deflection of the fixed ring 207 and the cross shaft 205, and provides a certain range for deflection buffering. The fixed ring 207 is symmetrically installed along the center position of the axis of the slot shaft 203, and the elastic cover 206 is fixedly installed between the fixed ring 207 and the fixed wheel 210.

[0035] A connecting shaft 202 is rotatably installed on the inner wall of the frame 1. There are two connecting shafts 202 and they are symmetrically installed along the center position of the axis of the side plate 201. A transmission belt 204 is installed on the outer side of the connecting shaft 202 for transmission. A rotating wheel 209 is rotatably installed on the outer side of the fixed wheel 210. The rubber ring 208 on the outer side of the rotating wheel 209 cooperates with the transmission belt 204 to make the top of the plate contact the rubber ring 208 and the bottom of the plate contact the transmission belt 204. In the process of the plate being rolled and shaped and driven to move, the rotating wheel 209 is driven to rotate under the restriction of the fixed wheel 210 and the cross shaft 205 through the rotational connection between the rotating wheel 209 and the fixed wheel 210 and the friction between the plate and the rubber ring 208. A rubber ring 208 is fixedly installed on the outer side of the rotating wheel 209, and the bottom of the outer side of the rubber ring 208 contacts the top of the transmission belt 204.

[0036] The second embodiment is based on the first embodiment. Figures 5 and 6As shown, the material guide mechanism 3 includes a fixed plate 31, a material guide plate 32 is fixedly installed at the center position of the top of the fixed plate 31, slot blocks 33 are fixedly installed on both sides of the top of the fixed plate 31, and the outer sides of the slot blocks 33 are provided with inclined grooves, and the inclined grooves are inclined from bottom to top to the side away from the anti-bias mechanism 2, and a pressing roller 34 is rotatably installed in the inclined groove of the slot block 33, and an elastic ring 36 is fixedly installed in the inclined groove of the slot block 33, and the composite current collector plate driven by the roller pressing and shaping is moved from the anti-bias mechanism 2 to the rolling mechanism 4. The moving plate is supported at the bottom of the plate by the guide plate 32, so that the plate moves toward the rolling mechanism 4, and in the process of moving, it is supported at the top of the plate by the pressure roller 34. At the same time, in the process of the plate passing through, due to the different thickness of the plate, when the plate passes through, the bottom of the plate is restricted by the guide plate 32, and the pressure roller 34 is lifted upward, so that the two ends of the pressure roller 34 squeeze the elastic ring 36 upward, so that the elastic ring 36 is deformed, and the two ends of the outer side of the pressure roller 34 fit with the elastic ring 36. The groove block 33 is fixedly installed with a connecting block 37 on the top of the side of the rolling mechanism 4, and an arc panel 35 is fixedly installed between the connecting blocks 37. The bottom of the arc panel 35 is an arc surface, and the side of the bottom of the arc panel 35 close to the pressure roller 34 is convex downward. After the plate passes through the pressure roller 34, the plate enters the space between the guide plate 32 and the arc panel 35. At the same time, in the process of transmitting the plate to the rolling mechanism 4, the convex arc surface of the bottom of the arc panel 35 close to the side of the pressure roller 34 is used to limit the plate so that it is The top of the guide plate 32 is in contact with the plate, and during the roller shaping process, due to the deformation of the plate, the side of the plate close to the guide plate 32 is deformed and bent. At this time, the concave arc surface of the bottom of the guide plate 32 away from the side of the pressure roller 34 provides a certain range for the deformation and bending of the plate, so that the plate can be smoothly shaped. At the same time, the arc panel 35 restricts the plate to avoid wrinkles after shaping due to deformation and bending during the shaping process, and the bottom of the arc panel 35 is concave upward on the side away from the pressure roller 34.

[0037] The third embodiment is based on the first and second embodiments. Figures 7 to 9As shown, the rolling mechanism 4 includes a support frame 401, the bottom of the support frame 401 is fixedly connected to the top of the frame body 1, and a fixed shaft 402 is rotatably installed on the inner wall of the support frame 401, one end of the fixed shaft 402 is transmission-connected to the output end of the motor 5 through a transmission assembly 6, a fixed roller 403 is fixedly installed at the center position of the outer side of the fixed shaft 402, and a chute block 404 is fixedly installed on the top of the support frame 401 away from the material guide mechanism 3. A roller groove is opened on the outer side of the chute block 404, and the roller groove is inclined from bottom to top toward the side away from the material guide mechanism 3, and the motor 5 utilizes the transmission assembly to drive the roller 403 to rotate. 6 drives the fixed shaft 402 to rotate, so that the fixed shaft 402 drives the fixed roller 403 to rotate, so that the plate is extruded and shaped under the cooperation of the fixed roller 403 and the sliding roller 407, and drives the plate to move. When the fixed roller 403 cooperates with the sliding roller 407, the sliding roller 407 is driven by the spring 410 to drive the connecting column 409 to push the pressing roller plate 408 obliquely downward to contact the surface of the plate. A sliding shaft 405 is slidably installed in the roller groove of the inclined groove block 404, and rings 412 are fixedly installed at both ends of the outer side of the sliding shaft 405. The sliding roller 407 is fixedly installed at the center position of the outer side of the sliding shaft 405.

[0038] A limiting plate 406 is fixedly installed between the chute blocks 404, and a connecting column 409 is slidably installed on the inner wall of the limiting plate 406. A pressure roller plate 408 is installed at the bottom end of the connecting column 409. The bottom of the pressure roller plate 408 fits with the outer side of the sliding roller 407. A positioning ring is provided at the top of the connecting column 409, and a spring 410 is fixedly installed between the positioning ring and the limiting plate 406. A positioning plate 413 is slidably installed at the roller groove of the chute block 404, and a threaded rod 411 is rotatably installed on the top of the positioning plate 413. Before rolling, the worker twists the threaded rod 411 with a wrench to make the threaded rod 411 connected with the chute block 404 through the thread, and cooperates with the rotation connection between the threaded rod 411 and the positioning plate 413 to change the position of the positioning plate 413 in the roller groove of the chute block 404, thereby limiting the maximum distance between the sliding roller 407 and the fixed roller 403. The outer side of the threaded rod 411 is threadedly connected to the inner wall of the chute block 404.

[0039] When in use, a worker passes one end of the composite current collector plate through the anti-deviation mechanism 2, the material guiding mechanism 3 and the rolling mechanism 4 in sequence, and then starts the motor 5, so that the motor 5 drives the rolling mechanism 4 to operate through the transmission assembly 6. During the operation of the rolling mechanism 4, the composite current collector plate is rolled and shaped, and the composite current collector plate is driven to move. At the same time, during the movement, the plate is positioned by the anti-deviation mechanism 2, and cooperates with the material guiding mechanism 3 to guide the composite current collector plate.

[0040] When the moving plate is positioned by the anti-deflection mechanism 2, the rubber ring 208 on the outside of the rotating wheel 209 cooperates with the transmission belt 204, so that the top of the plate contacts the rubber ring 208, and the bottom of the plate contacts the transmission belt 204. In the process of the plate being rolled and shaped and driven to move, the rotating wheel 209 and the fixed wheel 210 are connected in rotation, and the friction between the plate and the rubber ring 208 is used to drive the rotating wheel 209 to rotate under the restriction of the fixed wheel 210 and the cross shaft 205. When the plate is rolled and shaped, due to the uneven thickness of the plate, the moving direction tends to deviate, and the deflection force is transmitted to the rubber ring 208 and the rotating wheel 209 through the composite current collector plate. At the same time, after receiving the deflection force, it is transmitted to the fixed ring 207 and the cross shaft 205 through the rotating wheel 209, so that the cross shaft 205 has a tilting tendency in the shaft groove of the slot shaft 203, so that the elastic cover 206 limits the deflection of the fixed ring 207 and the cross shaft 205, and provides a certain range for deflection buffering.

[0041] When passing through the material guide mechanism 3, the composite current collector plate driven by the roller pressing and shaping moves from the anti-bias mechanism 2 to the roller pressing mechanism 4. The moving plate is supported at the bottom of the plate by the material guide plate 32, so that the plate moves toward the roller pressing mechanism 4, and in the process of moving, the plate is supported at the top of the plate by the pressure roller 34. At the same time, in the process of the plate passing through, due to the different thickness of the plate, when the plate passes through, the bottom of the plate is restricted by the material guide plate 32, and the pressure roller 34 is lifted up, so that the two ends of the pressure roller 34 squeeze the elastic ring 36 upward, so that the elastic ring 36 is deformed. At the same time, after the plate passes through the pressure roller 34, the plate enters the material guide plate In the space between 32 and the arc panel 35, while transmitting the sheet to the rolling mechanism 4, the convex arc surface at the bottom of the arc panel 35 close to the pressure roller 34 is used to limit the sheet so that it contacts the top of the guide plate 32. At the same time, during the roller shaping process, due to the deformation of the sheet, the side of the sheet close to the guide plate 32 is deformed and bent. At this time, the concave arc surface at the bottom of the guide plate 32 away from the pressure roller 34 provides a certain range for the deformation and bending of the sheet, so that the sheet is smoothly shaped. At the same time, the arc panel 35 limits the sheet to avoid wrinkles caused by deformation and bending during the shaping process.

[0042] When the plate is shaped by the rolling mechanism 4, the fixed shaft 402 is driven to rotate by the motor 5 using the transmission assembly 6, so that the fixed shaft 402 drives the fixed roller 403 to rotate, so that the plate is extruded and shaped in cooperation with the fixed roller 403 and the sliding roller 407, and the plate is driven to move. When the fixed roller 403 cooperates with the sliding roller 407, the sliding roller 407 is driven by the spring 410 to drive the connecting column 409 to push the pressing roller plate 408 obliquely downward to contact the surface of the plate. Before rolling, the worker twists the threaded rod 411 with a wrench, so that the threaded rod 411 is connected to the inclined groove block 404 through the thread, and cooperates with the rotation connection of the threaded rod 411 and the positioning plate 413, so that the position of the positioning plate 413 in the roller groove of the inclined groove block 404 is changed, thereby limiting the maximum distance between the sliding roller 407 and the fixed roller 403.

[0043] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
