Description

Technical Field

[0001] The utility model relates to the technical field of conductive film production, and more specifically to a conductive metal film pressing roller mechanism and manufacturing equipment. Background Art

[0002] In today's era of rapid technological development, various electronic devices have become an important part of our daily lives and work. Behind these devices, batteries play an indispensable role.

[0003] Conductive metal film, as the name suggests, is a thin film material that combines electrical conductivity with metallic properties. It possesses excellent conductivity, strength, ductility, and stability, maintaining stable performance under various environmental conditions. These properties make it widely used in batteries. As positive or negative current collectors, it ensures current flow within the battery, improving its energy density and cycle life.

[0004] During the production of conductive metal films, pressure rollers are used in various stages, including vapor deposition, slitting, and packaging. These rollers apply pressure to maintain a stable state during production, preventing wrinkles and warping. They also fine-tune the surface of the conductive metal film to achieve a desired smoothness, enhancing product performance and quality.

[0005] However, the pressure roller in the prior art is usually set off-axis with the conductive metal film winding roller, which can also be understood as an eccentric setting, and is set above the winding roller, relying on its own weight to achieve tangency or offset with the winding roller. This not only limits the setting position of the pressure roller, but also as the conductive metal film on the winding roller gradually becomes thicker, the pressure generated by the pressure roller's own gravity on the conductive metal film along the radial direction of the winding roller gradually decreases, making it impossible to maintain a relatively stable pressure output. Therefore, the reliability of this pressure roller mechanism is poor. Utility Model Content

Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0027] In order to better understand the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments:

[0028] See also Figures 1 to 4 As shown, an embodiment of the present invention provides a conductive metal film pressing roller mechanism, which includes a frame 1, a driving cylinder 2 and a pressing roller assembly 4.

[0029] In this embodiment, the pressure roller assembly 4 includes a pressure roller 41 and two oppositely arranged first ear plates 42. The two oppositely arranged first ear plates 42 are combined to form a swing arm. The driving cylinder 2 and the swing arm are connected by a rotating shaft 5 and a connecting arm 3. Specifically, the output end of the driving cylinder 2 is connected to the lower end of the connecting arm 3, and the upper end of the connecting arm 3 is connected to the rotating shaft 5. When the driving cylinder 2 drives the connecting arm 3 to swing, the rotating shaft 5 rotates accordingly, thereby driving the swing arm connected to the rotating shaft 5 to swing around the central axis of the rotating shaft 5, so as to drive the pressure roller 41 to press on the conductive metal film with a certain pressure value or a pressure within a certain value range, so as to achieve the effect of removing the bulge, thereby keeping the conductive metal film in a tensioned state. Among them, technical personnel in this field can set the pressure value applied by the pressure roller 41 on the conductive metal film according to actual production needs. Therefore, no specific limitation is made here on the pressure value applied by the pressure roller 41 on the conductive metal film.

[0030] Specifically, the two ends of the pressure roller 41 are respectively connected to the two first ear plates 42 for rotation, and the connecting arm 3 and the first ear plate 42 are connected by the rotating shaft 5. The driving cylinder 2 drives the connecting arm 3 to swing to drive the rotating shaft 5 to rotate. When the rotating shaft 5 rotates, the first ear plate 42 swings around the central axis of the rotating shaft 5 to drive the pressure roller 41 to abut against the surface of the conductive metal film. With this design, the driving cylinder 2 can adapt to the swing caused by the pressure roller assembly 4 during movement in real time. On the premise of automatically adjusting its own position in real time, it can also ensure that the angle of the force applied to the connecting arm 3 changes but the magnitude of the force remains relatively stable, thereby ensuring that the pressure applied by the pressure roller 41 on the conductive metal film remains relatively stable, avoiding the unstable and uncontrollable pressure caused by the weight of the pressure roller 41 alone, thereby greatly improving the accuracy and reliability of the pressure roller mechanism.

[0031] The connecting arm 3 includes a base 31 and a bent portion 32. The base 31 and the bent portion 32 are formed by an integral molding process. The base 31 and the bent portion 32 form an angle between the base 31 and the bent portion 32, so that the connecting arm 3 has a curved section. This facilitates the connection of the lower end of the connecting arm 3 to the driving cylinder 2, and the upper end of the connecting arm 3 is conveniently fixed to the rotating shaft 5 via a flange connection. It is worth mentioning that the lower end of the connecting arm 3 and the free end of the push rod of the driving cylinder 2 are hinged to each other, so that the driving cylinder 2 can adapt to the swinging of the swing arm and the connecting arm 3 in real time. Under the premise of automatically adjusting its own position in real time, the driving cylinder 2 can also ensure that the angle of the force applied to the connecting arm 3 changes (adapting to the swinging angle of the swing arm and the connecting arm 3) but the magnitude of the force remains relatively stable. This ensures that the pressure applied to the conductive metal film by the swing arm and the pressure roller 41 remains relatively stable, avoiding the unstable and uncontrollable pressure caused by the weight of the pressure roller 41 alone, thereby greatly improving the accuracy and reliability of the pressure roller mechanism. In addition, the pressure roller 41 no longer relies on its own weight to apply force, and its location is no longer limited to being located above the winding roller 6.

[0032] See also Figures 1 and 2 As shown, the frame 1 is also provided with a winding roller 6 for winding the conductive metal film. The central axis of the winding roller 6, the central axis of the pressure roller 41, and the central axis of the rotating shaft 5 are arranged parallel to each other, thereby ensuring that the pressure roller 41 is always tangential to the conductive metal film. Specifically, the winding roller 6 includes a main body 61 and two protrusions 62. The two protrusions 62 are respectively provided at both ends of the main body 61, and the protrusions 62 protrude radially from the main body 61. The provision of the protrusions 62 effectively restrains the conductive metal film on the main body 61 during the winding process, thereby preventing the conductive metal film from deflecting or slipping during the winding process and ensuring winding accuracy.

[0033] See also Figure 1 and Figure 3As shown, two second ear plates 7 are installed on the frame 1, and each second ear plate 7 is provided with a mounting hole that penetrates its thickness. The two ends of the rotating shaft 5 pass through the mounting holes of the two second ear plates 7 respectively and are rotatably connected with the two second ear plates 7. This connection method enables the rotating shaft 5 to rotate around its own axis, and then the rotation of the rotating shaft 5 can be used to drive the swing arm to swing around the central axis of the rotating shaft 5. Under the drive of the driving cylinder, the pressure roller 41 mounted in the swing arm can approach the conductive metal film along a specific direction and always maintain a certain force to press on the surface of the conductive metal film.

[0034] To reduce wear on the rotating shaft 5 and extend its service life, in this embodiment, a rotating component is disposed within the mounting hole and sleeved onto the rotating shaft 5 to rotatably connect the rotating shaft 5 to the second lug 7. More specifically, the rotating component is a bearing or a sleeve. This design helps reduce friction between the rotating shaft 5 and the second lug 7, thereby reducing resistance during rotation. This not only improves the rotation efficiency of the rotating shaft 5 but also extends its service life.

[0035] Preferably, the pressure roller assembly 4 also includes at least one connecting rod 43 and a sleeve 44. Both the connecting rod 43 and the sleeve 44 are mounted between the two first lugs 42, with the sleeve 44 positioned below the two first lugs 42 and the pressure roller 41 positioned above the two first lugs 42. This arrangement stabilizes the overall center of gravity of the pressure roller assembly 4, further enhancing structural stability. More specifically, one of the sleeve 44 and the rotating shaft 5 is provided with a threaded hole, and the other of the sleeve 44 and the rotating shaft 5 is provided with a bolt 9 that engages with the threaded hole. The bolt 9 is inserted into the threaded hole to securely connect the sleeve 44 and the rotating shaft 5. This design makes the connection between the sleeve 44 and the rotating shaft 5 quick and easy, requiring only a few simple rotations to insert and secure the bolt 9, significantly improving installation efficiency. Furthermore, the use of a hinged hole bolt as the bolt 9 improves the shear resistance of the pressure roller assembly 4, allowing it to withstand greater shear forces. This not only increases the overall strength of the pressure roller assembly 4 but also makes the pressure roller assembly 4 more stable during operation.

[0036] Preferably, positioning holes are provided at corresponding positions of the sleeve 44 and the rotating shaft 5, and positioning pins 10 are inserted into the positioning holes for fixing the sleeve 44 and the rotating shaft 5, which not only enhances the connection strength between the sleeve 44 and the rotating shaft 5, but also prevents the sleeve 44 and the rotating shaft 5 from relative rotation or dislocation.

[0037] Preferably, an articulated support 8 is installed at the lower part of the frame 1. In order to facilitate quick installation and disassembly, in this embodiment, the articulated support 8 is fixed to the lower part of the frame 1 by bolts 9, and the tail of the cylinder body of the driving cylinder 2 is hinged to the articulated support 8.

[0038] In this embodiment, the length of the working surface of the pressing roller 41 is 300 mm to 2000 mm, and the length of the working surface matches the width of the conductive metal film.

[0039] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.

[0040] The above is an exemplary description of the present utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the present utility model patent is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present utility model patent, or the concept and technical solution of the present utility model patent are directly applied to other occasions without improvement, they are all within the scope of protection of the present utility model.
