[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.
[0025] Regarding the structure of a wrinkle-removing roller, the present invention provides a specific embodiment, referring to... Figure 1As shown, the wrinkle-removing roller in this embodiment includes an annular roller surface, a supporting shaft 1, and a roller surface drive assembly. The supporting shaft 1 passes through the center of the annular roller surface, and the annular roller surface is slidably mounted on the supporting shaft 1. The two ends of the supporting shaft 1 are rotatably mounted through bearing seats. The annular roller surface is divided into a left roller surface and a right roller surface along its radial cross-section. The roller surface drive assembly can drive the left roller surface and the right roller surface to separate or merge. The left roller surface and the right roller surface are each divided at least once along their axial direction. The left roller surface includes at least a first left roller surface 7 and a second left roller surface 8, and the right roller surface includes at least a first right roller surface 9 and a second right roller surface 10. When the substrate contacts the annular roller surface, this embodiment achieves a wrinkle-removing effect by moving away from the side of the annular roller surface that contacts the substrate, while moving towards the substrate on the side that does not contact the substrate. This ensures that the roller surface remains close to the substrate when in contact, thereby achieving continuous wrinkle removal and improving production quality and efficiency to a certain extent.
[0026] As a preferred embodiment, refer to Figure 2 As shown, the roller drive assembly includes a forward and reverse threaded rod 2 disposed opposite to each other inside the annular roller surface and a power mechanism for driving the forward and reverse threaded rod 2 to rotate. The forward and reverse threaded rods are provided with left-hand threads 3 and right-hand threads 4, and the left-hand threads 3 are provided with left-hand threaded sleeves 5, and the right-hand threads 4 are provided with right-hand threaded sleeves 6. The first left roller surface 7 and the first right roller surface 9 are respectively mounted on one of the forward and reverse threaded rods 2 through left-hand threads 3 and right-hand threads 4, and the second left roller surface 8 and the second right roller surface 10 are respectively mounted on the other forward and reverse threaded rod through left-hand threads 3 and right-hand threads 4. The power mechanism includes a drive motor 11, a motor fixing plate 12, an electric slip ring 13, and a coupling 14. The drive motor is mounted on the motor fixing plate 12, and the drive motor is rotatably connected to the forward and reverse threaded rods 2 through the coupling 14. The electric slip ring 13 is installed between the bearing seat and the drive motor 11. In this embodiment, the drive motor cable is connected to the electrical box via an electric slip ring, thereby achieving the purpose of supplying power to the motor.
[0027] In addition, continue to refer to Figure 2 as well as Figure 3As shown, the wrinkle-removing roller is also provided with four guide shafts 15, which are arranged in a matrix at the four corners of the support shaft 1. Roller surface fixing blocks 16 are provided on the concave surfaces of the first left roller surface 7, the second left roller surface 8, the first right roller surface 9, and the second right roller surface 10. The positive and negative threaded screws 2 and the guide shafts 15 located on the same side of the support shaft 1 are rotatably connected to the roller surface fixing blocks 16 on the same side. Linear bearings 17 and buffer limiting sleeves 18 are provided on the guide shafts. Two sets of linear bearings 17 are installed on each guide shaft 15, and the buffer limiting sleeves 18 are located between the two sets of linear bearings 17 on each guide shaft 15. Guide shaft fixing plates 19 and first threaded screw fixing plates 20 are also provided at both ends of the guide shaft 15. One end of the guide shaft 15 is installed on the support shaft 1 through the guide shaft fixing plate 19, and the other end of the guide shaft 15 and one end of the positive and negative threaded screws 2 are installed on the support shaft 1 through the first threaded screw fixing plate 20. The other end of the positive and negative threaded screw 2 is also provided with a second screw fixing plate 21, and the other end of the positive and negative threaded screw 2 is mounted on the support shaft 1 through the second screw fixing plate 21. Through the connection relationship between the annular roller surface, the positive and negative threaded screw, and the guide shaft, it is ensured that the annular roller surface slides synchronously with the linear bearing on the same side and the left-hand threaded sleeve / right-hand threaded sleeve on the same side. In addition, the buffer limit sleeve is to prevent the linear bearing from moving excessively on the guide shaft.
[0028] As a preferred embodiment, refer to Figure 4 and Figure 5 As shown, the wrinkle-removing roller also includes a detection mechanism, which includes a sensor 22, a sensor sensing plate 23, a sensor sensing ring 24, and a sensor sensing base 25. The sensor 22 is installed between the sensor sensing plate 23 and the sensor sensing ring 24 via the sensor sensing base 25. The sensor sensing plate 23 is a circular cover with a notch, and a reset button 26 is also provided at the notch. The sensor sensing ring 24 is a circular ring with two notches, and the sensor sensing ring 24 is fixedly installed on the support shaft 1. In this embodiment, two sets of sensors and sensor fixing bases are axially symmetrically arranged at the edge of the sensor sensing plate port. The starting position of the notch of the sensor sensing ring is exactly relative to the sensor installation position. In this embodiment, the sensor is a photoelectric switch, which can control the movement state of the positive and negative thread screws by detecting the position of the sensor sensing ring. In addition, the wrinkle-removing roller in this embodiment is also equipped with a touch screen. In this embodiment, the stretching amount on the substrate can be controlled by adjusting the stroke of the annular roller surface away from the moving surface through the parameter settings on the touch screen, thereby further improving the production quality and efficiency of the substrate.
[0029] A lithium battery manufacturing apparatus includes the wrinkle-removing roller described above.
[0030] The working principle of this invention is as follows: This scheme divides the annular roller surface radially into a left roller surface and a right roller surface, and the left roller surface and the right roller surface are each divided at least once along their axial direction. When the substrate contacts the roller surface, the roller surface in contact with the substrate moves away under the drive of the drive motor and the positive and negative threaded rods, and stretches the substrate to both sides under the action of friction to achieve the effect of wrinkle removal. At the same time, the roller surface that is not in contact with the substrate moves towards the substrate under the drive of the drive motor and the positive and negative threaded rods, so that the roller surface closes. This ensures that the roller surfaces on both sides are in a closed state every time the substrate contacts the roller surface, so that the roller surface is always moving away when it contacts the substrate, and the substrate is always in a state of stretching to both sides when it contacts the roller surface. In addition, the amount of stretching on the substrate can be controlled by adjusting the stroke of the roller surface moving away through the parameter settings on the touch screen.
[0031] Through the above structure, the present invention can set different movement amounts according to the wrinkling of the substrate, and can ensure that the roller face can continuously remove wrinkles from the substrate, thereby improving production quality and efficiency to a certain extent.
[0032] The above is a detailed description of the preferred embodiments of the present invention. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
