Description

Technical Field

[0001] This application belongs to the technical field of rolling equipment and battery equipment, and specifically relates to a rolling mechanism. Background Technology

[0002] Roller activation is a common process in the automated assembly line of the lithium battery packaging industry. Existing technologies require two actuators to complete the force control and roller displacement in two steps. One actuator controls the distance the roller rises to achieve force control, while the other actuator controls the direction and distance of the roller's movement to achieve rolling displacement.

[0003] However, the above method results in a larger overall machine size, and performing force control and rolling displacement in two steps will affect the overall production line cycle time and reduce production efficiency. Utility Model Content

[0004] The purpose of this application embodiment is to provide a rolling mechanism that can solve at least one of the problems of large size and low production efficiency.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides a rolling mechanism, including: a drive assembly, a first mounting base, a second mounting base, a first elastic element, and a roller assembly;

[0007] The drive component is connected to the first mounting base and is used to drive the first mounting base to move in a first direction;

[0008] The first mounting base has an inclined surface, and the angle between the inclined surface and the first direction is greater than 0° and less than 90°;

[0009] The second mounting base is movably disposed on the inclined surface;

[0010] The first elastic element is elastically connected to the first mounting base and the second mounting base;

[0011] The roller assembly is disposed on the second mounting base, and the roller assembly includes a roller body that is rotatable relative to the second mounting base.

[0012] In this embodiment, the inclined surfaces of the second mounting base and the first mounting base engage, allowing the second mounting base to have both a movement component in the first direction and a movement component in a direction perpendicular to the first direction. Thus, under the combined action of the drive assembly and the first elastic element, reliable control can be achieved over the extrusion force (or the bonding force of the roller assembly on the product material) experienced by the roller assembly during the bonding process, as well as the movement displacement of the roller assembly. Therefore, this embodiment can simultaneously achieve force control of the roller assembly in the first direction and the movement distance of the roller assembly in the direction perpendicular to the first direction using a single mechanism. Compared to related technologies that use two separate mechanisms to perform force control and movement distance, this embodiment reduces the overall size of the mechanism and shortens the bonding time, improving the overall line cycle time and production efficiency.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0031] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0032] refer to Figures 1 to 6 This application discloses a rolling mechanism that can be used to achieve the bonding process of product auxiliary materials. For example, the rolling mechanism can be applied to the bonding process of battery product auxiliary materials. Of course, it can also be applied to other situations, which are not specifically limited here. The disclosed rolling mechanism includes a drive assembly 10, a first mounting base 20, a second mounting base 30, a first elastic member 41, and a roller assembly 50.

[0033] The roller assembly 50 is the core component of the rolling mechanism, which can roll and bond product accessories. The roller assembly 50 includes a roller body 51, which can both squeeze the product accessories and roll on the product accessories to meet the requirements of rolling and bonding of product accessories.

[0034] The second mounting base 30 is a load-bearing component, and the roller assembly 50 can be mounted on the second mounting base 30 to ensure the stability of the roller assembly 50. Furthermore, the roller body 51 can rotate relative to the second mounting base 30 to facilitate rolling and bonding of product accessories. It should be noted that the roller body 51 can be directly rotatably connected to the second mounting base 30, or it can be indirectly rotatably connected to the second mounting base 30 through other components, depending on the actual working conditions.

[0035] The drive assembly 10 is a power component that provides driving force; the first mounting base 20 is a load-bearing component that supports other components. The drive assembly 10 is connected to the first mounting base 20 and drives the first mounting base 20 to move in a first direction. Optionally, the first direction can be a vertical direction, the direction of gravity, or the height direction of the rolling mechanism, etc., and of course, it can be other directions as well, without specific limitation here. For example, when the rolling mechanism needs to roll vertically, the first direction is the vertical direction or the direction of gravity; when the rolling mechanism needs to roll horizontally, the first direction is the horizontal direction.

[0036] In order to enable the roller assembly 50 to move in the first direction, in this embodiment of the application, the second mounting base 30 can be disposed on the first mounting base 20. In this way, under the driving action of the driving component 10, the first mounting base 20 can drive the second mounting base 30 to move, and the second mounting base 30 can drive the roller assembly 50 to move synchronously in the first direction.

[0037] In order to enable the second mounting base 30 to move relative to the first mounting base 20 in the first direction and in other directions that form a certain angle with the first direction, in this embodiment of the application, the first mounting base 20 may be provided with an inclined surface 231, the angle between the inclined surface 231 and the first direction being greater than 0° and less than 90°, and the second mounting base 30 is movably disposed on the inclined surface 231.

[0038] Based on the above configuration, the second mounting base 30 and the roller assembly 50 it supports can move along the extension direction of the inclined surface 231. This allows the second mounting base 30 to have a movement component in both the first direction and a direction perpendicular to the first direction, thereby ensuring that the roller assembly 50 moves simultaneously in both the first direction and the direction perpendicular to the first direction to meet the product accessory bonding requirements. It should be noted that the inclined surface 231 exists to allow the roller assembly 50 to transmit the force to the second mounting base 30 when subjected to compression during bonding, enabling the second mounting base 30 to move both in the first direction and in the direction perpendicular to the first direction.

[0039] Optionally, the angle between the inclined surface 231 and the first direction can be in the range of 10° to 80°, such as 5°, 10°, 15°, 20°, 30°, 45°, 50°, 60°, 75°, 80°, etc. Of course, it can also be other degrees, which are not specifically limited here.

[0040] In some more specific embodiments, the first direction can be a vertical direction, and the angle between the inclined surface 231 and the first direction can be 75°.

[0041] To prevent the second mounting base 30 from moving arbitrarily along the inclined surface 231 relative to the first mounting base 20, a first elastic element 41 is elastically connected to the first mounting base 20 and the second mounting base 30. Thus, under the elastic force of the first elastic element 41, the second mounting base 30 can be effectively prevented from moving arbitrarily along the inclined surface 231, thereby ensuring the stability of the second mounting base 30 and the roller assembly 50 it supports. Optionally, the first elastic element 41 can be a spring, elastic strip, elastic sheet, or other similar structure.

[0042] Based on the above, under the combined action of the drive component 10 and the first elastic element 41, reliable control can be achieved over the extrusion force (or the bonding force of the roller assembly 50 on the product auxiliary material) experienced by the roller assembly 50 during the bonding process, as well as the movement displacement of the rolling assembly. Therefore, this embodiment can simultaneously achieve force control of the roller assembly 50 in the first direction and the movement distance of the roller assembly 50 in the direction perpendicular to the first direction using a single mechanism. Compared to the related technologies that use two separate mechanisms to execute force control and movement distance, this embodiment can reduce the overall size of the mechanism and shorten the bonding time, thereby improving the overall line cycle time and production efficiency. It should be noted that the elastic force of the first elastic element 41 is the product of the elastic coefficient (or stiffness coefficient) and the elastic deformation.

[0043] To ensure smooth movement of the second mounting base 30 relative to the first mounting base 20, the rolling mechanism may further include a first slide rail 61 and a first slider 62, with the first slider 62 slidably connected to the first slide rail 61. Alternatively, one of the first slide rail 61 and the first slider 62 may be located on the inclined surface 231, and the other may be located on the surface of the second mounting base 30 facing the inclined surface 231. Specifically, the first slide rail 61 may be located on the inclined surface 231 and extend along the extension direction of the inclined surface 231, while the first slider 62 may be located on the surface of the second mounting base 30 facing the inclined surface 231. Alternatively, the first slide rail 61 may be located on the surface of the second mounting base 30 facing the inclined surface 231, with the extension direction of the first slide rail 61 parallel to the extension direction of the inclined surface 231, and the first slider 62 may be located on the inclined surface 231.

[0044] Based on the above configuration, the sliding connection between the first slider 62 and the first slide rail 61 ensures that the second mounting base 30 moves smoothly relative to the first mounting base 20 along the extension direction of the inclined surface 231, which helps to improve the stability of the second mounting base 30 and the roller assembly 50 it carries.

[0045] To further improve the smoothness of movement of the second mounting base 30 and the roller assembly 50, the rolling mechanism may further include a first guide rod 71. The first guide rod 71 is fixedly connected to one of the first mounting base 20 and the second mounting base 30, and slidably connected to the other of the first mounting base 20 and the second mounting base 30. Based on this, the first guide rod 71 can guide the second mounting base 30, thereby further improving the smoothness of movement of the second mounting base 30 and the roller assembly 50 it supports. Optionally, the first mounting base 20 may have a first guide hole, with the first guide rod 71 fixedly connected to the second mounting base 30 and slidably passing through the first guide hole; alternatively, the second mounting base 30 may also have a first guide hole, with the first guide rod 71 fixedly connected to the first mounting base 20 and slidably passing through the first guide hole.

[0046] In addition, the first elastic member 41 can be sleeved on the outside of the first guide rod 71. In this way, the first guide rod 71 can also guide and limit the first elastic member 41 to prevent the first elastic member 41 from twisting.

[0047] In some embodiments, the roller assembly 50 may further include a roller bracket 52, with the roller body 51 rotatably connected to the roller bracket 52. This ensures that the roller bracket 52 can install the roller body 51 and ensures the smooth rotation of the roller body 51.

[0048] Considering that the drive assembly 10 drives the roller assembly 50 to move in the first direction through the first mounting base 20 and the second mounting base 30, so that the roller body 51 can contact the product material, in order to prevent the roller body 51 from exerting a large squeezing force on the product material and causing damage to the product material and the product body, in this embodiment of the application, the roller bracket 52 is movably disposed on the second mounting base 30 in the first direction, and the rolling mechanism may further include a second elastic member 42, which elastically connects the roller bracket 52 and the second mounting base 30.

[0049] Based on the above configuration, when the roller body 51 contacts the product auxiliary material, as the drive assembly 10 continues to drive the roller assembly 50 to move in the first direction, the second mounting base 30 and the roller assembly 50 can not only move along the inclined surface 231 of the first mounting base 20, but also the roller bracket 52 can squeeze the second elastic member 42 and move relative to the second mounting base 30 in the first direction. This can effectively prevent the roller body 51 from exerting a large squeezing force on the product auxiliary material and the product body, and ensure the integrity of the product auxiliary material and the product.

[0050] It should be noted that by adjusting the movement distance of the first mounting base 20 in the first direction driven by the drive assembly 10, the movement distance of the second mounting base 30 relative to the first mounting base 20 along the inclined surface 231 (corresponding to the compression amount of the first elastic element 41), the movement distance of the roller bracket 52 relative to the second mounting base 30 in the first direction (corresponding to the compression amount of the second elastic element 42), and the angle between the inclined surface 231 and the first direction, the extrusion force of the roller body 51 on the product auxiliary material can be controlled, thereby effectively preventing excessive extrusion force from causing damage to the product auxiliary material and the product body.

[0051] To ensure smooth movement of the roller bracket 52 relative to the second mounting base 30, the rolling mechanism may further include a second slide rail 63 and a second slider 64, with the second slider 64 slidably connected to the second slide rail 63. Alternatively, one of the second slide rail 63 and the second slider 64 may be located on the second mounting base 30, and the other may be located on the roller bracket 52. Specifically, the second slide rail 63 may be located on the second mounting base 30, and the second slider 64 may be located on the roller bracket 52. Of course, the second slide rail 63 may also be located on the roller bracket 52, and the second slider 64 may also be located on the second mounting base 30.

[0052] Based on the above configuration, the sliding connection between the second slider 64 and the second slide rail 63 ensures that the roller bracket 52 moves smoothly relative to the first mounting base 20 in the first direction, which helps to improve the stability of the second mounting base 30 and the roller assembly 50 it carries.

[0053] To further improve the smoothness of the movement of the roller bracket 52, the rolling mechanism may further include a second guide rod 72. The second guide rod 72 is fixedly connected to one of the roller bracket 52 and the second mounting base 30, and slidably connected to the other of the roller bracket 52 and the second mounting base 30. Based on this, the second guide rod 72 can guide the roller bracket 52, thereby further improving the smoothness of its movement. Optionally, the roller bracket 52 may be provided with a second guide hole, and the second guide rod 72 is fixedly connected to the second mounting base 30 and slidably passes through the second guide hole; alternatively, the second mounting base 30 may also be provided with a second guide hole, and the second guide rod 72 is fixedly connected to the roller bracket 52 and slidably passes through the second guide hole.

[0054] In addition, the second elastic member 42 can be sleeved on the outside of the second guide rod 72. In this way, the second guide rod 72 can also guide and limit the second elastic member 42 to prevent the second elastic member 42 from twisting.

[0055] In some embodiments, the drive assembly 10 may include a linear module 11, which includes a drive end connected to the first mounting base 20. The drive end is used to drive the first mounting base 20 to move in a first direction. Based on this, under the driving action of the linear module 11, it can be ensured that the first mounting base 20 can move in the first direction without deviation.

[0056] Optionally, the linear module 11 may include a cylinder, a hydraulic cylinder, an electric cylinder, a matching lead screw and slider, etc. Of course, it may also be in other forms, which are not specifically limited here.

[0057] To prevent excessive movement of some components, the rolling mechanism may further include a limiting block 81 and a limiting switch 82. One of the limiting block 81 and the limiting switch 82 may be located on the drive assembly 10, and the other may be located on the first mounting base 20. The limiting block 81 and the limiting switch 82 are arranged opposite to each other in the first direction. Therefore, during the process of the drive assembly 10 driving the first mounting base 20 to move in the first direction, the cooperation between the limiting switch 82 and the limiting block 81 ensures that the first mounting base 20 does not move excessively, further ensuring that the roller assembly 50 does not move excessively, effectively preventing contact between components.

[0058] In some embodiments, the first mounting base 20 may include a movable plate 21, an adapter plate 22, and a support plate 23. The movable plate 21 is connected to the drive end of the drive assembly 10, and the support plate 23 has an inclined surface 231. The movable plate 21, adapter plate 22, and support plate 23 are connected sequentially; alternatively, two of the movable plate 21, adapter plate 22, and support plate 23 may be integrally formed and connected to the third of the three; or, the movable plate 21, adapter plate 22, and support plate 23 may be integrally formed.

[0059] Based on the above settings, a reliable connection between the first mounting base 20 and the drive assembly 10 can be ensured, and stable support can be achieved for the second mounting base 30 and the roller assembly 50 it carries.

[0060] Optionally, the movable plate 21 can be connected to the drive end of the linear module 11, the adapter plate 22 can be fixedly connected to the movable plate 21, and the adapter plate 22 and the carrier plate 23 can be integrally set; in addition, the limit block 81 can be installed on the movable plate 21, and the limit switch 82 can be installed on the housing of the linear module 11.

[0061] To increase the rolling area, the rolling mechanism may include multiple roller assemblies 50 arranged side by side in a second direction, with the axes of the roller bodies 51 of the multiple roller assemblies 50 being collinear, wherein the second direction is perpendicular to the first direction. In some embodiments, the first direction may be a vertical direction, and the second direction may be a horizontal direction.

[0062] Based on the above configuration, the roller bodies 51 of multiple roller assemblies 50 can be used together for rolling, thereby increasing the contact area with the product materials and increasing the rolling area, which is beneficial to improving the rolling efficiency.

[0063] In some embodiments, the rolling mechanism may further include a fixing frame 90, on which the drive assembly 10 may be mounted to ensure the stability of the drive assembly 10. Exemplarily, the fixing frame 90 may be an L-shaped plate structure, a T-shaped plate structure, a frame, etc.

[0064] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
