Description

Technical Field

[0001] This utility model relates to the technical field of coating machines, and in particular to the technical field of a high-frequency, high-efficiency experimental battery material coating machine. Background Technology

[0002] In the field of battery production and R&D, the composition and proportioning of the material between the film materials in battery cells (which is a viscous liquid during production and needs to be evenly spread on the electrode film material, then stacked or rolled into a roller and dried to become solid) is crucial, requiring extensive testing. However, in the R&D experimental stage, due to the inability to use batch processing equipment, spreading the viscous liquid material evenly on the film material each time becomes an extremely challenging task. Uneven spreading of the material will directly lead to unevenness between the battery cells, which will seriously affect the overall conductivity of the battery, hindering the accurate acquisition of experimental data and the optimization of battery performance. Therefore, to solve the problem of difficulty and poor effect in material spreading during R&D experiments, there is an urgent need for a device that can achieve uniform material spreading and facilitate adjustment of spreading thickness. Utility model patent with patent number CN202311357006.X discloses a uniform coating mechanism for a horizontal coating machine. When the coating machine is working, the scraping slope is close to the coating surface of the film or paper. In this way, under the action of the scraping slope, excess coating can be scraped off the film or paper and collected into the coating collection box, ensuring the uniformity of coating. However, this coating machine is not suitable for small-batch, high-frequency, intermittent use in laboratories. For materials from different years, a single sheet of film cannot be well fixed, and it cannot guarantee that liquid materials can be efficiently and uniformly covered on the film under high-frequency use conditions. Utility Model Content

Detailed Implementation

[0021] See Figure 1 and Figure 2 This utility model discloses a high-frequency, high-efficiency experimental battery material coating machine, comprising a worktable 1, a material-equalizing guide rail 2, a material-equalizing sliding mechanism 3, a flattening and solidifying film holder 4, a thickness adjustment mechanism 5, and a material-spreading mechanism 6. The worktable 1 is equipped with the material-equalizing guide rail 2, and the material-equalizing sliding mechanism 3 is mounted on the material-equalizing guide rail 2. The material-equalizing sliding mechanism 3 is used to move the material on the material-equalizing guide rail 2. The material in this application is the substance between the film materials in the battery cell. This substance is in a viscous liquid state during production and needs to be evenly spread on the electrode film material, then stacked or rolled into a roller, and becomes a solid material after drying. The material-equalizing sliding mechanism 3 is equipped with a flattening and solidifying film holder 4, which is used to flatten and fix the film material. Figure 2 and Figure 3As shown, the material leveling sliding mechanism 3 includes a material leveling sliding guide seat 31, a material leveling sliding frame 32, and a material leveling sliding linear motor 33. The material leveling sliding guide seat 31 is fixedly mounted on the lower side of the material leveling sliding frame 32. The material leveling sliding linear motor 33 is arranged between the worktable 1 and the material leveling sliding frame 32. The material leveling sliding linear motor 33 is used to drive the material leveling sliding frame 32 to move along the material leveling guide rail 2. By driving the material leveling sliding guide seat 31 and the material leveling sliding frame 32 to slide on the material leveling guide rail 2, the material leveling is achieved by the material leveling mechanism 6. At the same time, as Figure 3 As shown, the material equalization sliding guide seat 31 is set on the material equalization guide rail 2. With the cooperation of the material equalization guide rail 2 and the material equalization sliding guide seat 31, the material equalization sliding frame 32 can be guaranteed to move in a straight line, so that the material is flattened along the direction of movement.

[0022] like Figure 6 and Figure 7 As shown, a cavity is provided inside the flattening and solidifying film holder 4. Solid material suction holes 41, communicating with the cavity, are evenly spaced on the upper surface of the flattening and solidifying film holder 4. A pipe joint for extracting air from the cavity is provided on the side of the flattening and solidifying film holder 4. By connecting an external air extraction device, the air in the cavity is removed, creating a negative pressure within the cavity. This allows the solid material suction holes 41 to adsorb and fix the battery film material, preventing the battery film material from moving during the flattening process. A thickness adjustment mechanism 5 is provided on the worktable 1 to adjust the coating thickness. A spreading mechanism 6 is also provided on the thickness adjustment mechanism 5 to evenly spread the material. According to technical requirements, the material needs to be spread evenly; otherwise, unevenness between the battery cells will affect the overall conductivity. By raising and lowering the spreading mechanism 6 through the thickness adjustment mechanism 5, the distance between the spreading mechanism 6 and the material can be changed, thereby adjusting the thickness of the material after flattening.

[0023] like Figure 4 As shown, the thickness adjustment mechanism 5 includes a thickness adjustment seat 51, a thickness adjustment lifting guide rail 52, a thickness adjustment guide rail seat 53, a thickness lifting seat 54, a thickness adjustment lifting screw sleeve 55, a thickness adjustment lifting motor 56, and a thickness adjustment lifting screw 57. The thickness adjustment lifting guide rail 52 is vertically mounted on the thickness adjustment seat 51, the thickness adjustment guide rail seat 53 is mounted on the thickness adjustment lifting guide rail 52, and the thickness lifting seat 54 is mounted on the thickness adjustment guide rail seat 53. The thickness adjustment lifting motor 56 is vertically fixed at the upper end of the thickness adjustment seat 51. The thickness adjustment lifting screw 57 is connected to the rotating shaft of the thickness adjustment lifting motor 56 and passes through the thickness adjustment lifting screw sleeve 55 fixed on the thickness lifting seat 54. The rotation of the thickness adjustment lifting motor 56 drives the thickness adjustment lifting screw 57 to rotate, which in turn drives the thickness adjustment lifting screw sleeve 55, the thickness lifting seat 54, and the thickness adjustment guide rail seat 53 to rise and fall, ultimately adjusting the distance between the spreading mechanism 6 and the flat film mounting seat 4.

[0024] like Figure 5 As shown, the material spreading mechanism 6 includes a spreading rod base 61, a rod body 62, and a cut 63. Spreading rod bases 61 are respectively provided at both ends of the rod body 62. The rod body 62 has a cut 63 that forms a vertical cross-section on its arc surface. The material is scraped flat through the cut 63 on the rod body 62, and the arc surface on the other side of the cut 63 can compact the material to a certain extent as it passes over the material surface. Furthermore, a vibration motor is installed inside the rod body 62. The vibration motor includes a vibration motor and an eccentric block, with the eccentric block fixed on the rotating shaft of the vibration motor. The high-speed rotation of the vibration motor drives the eccentric block to rotate at high speed, thereby causing the rod body 62 to vibrate. This reduces the adhesion of material to the rod body 62, preventing uneven surface caused by localized material removal due to material stickiness. Simultaneously, the vibration allows the material to be spread and compacted in situ.

[0025] The working process of this utility model:

[0026] This utility model discloses a high-frequency, high-efficiency experimental battery material coating machine. During operation, the battery film material is first placed on a flat, solidifying base 4. An external air extraction device is used to extract air from the inner cavity of the flat, solidifying base 4 via a pipe connector, creating negative pressure in the material suction holes 41 to adsorb and fix the battery film material. Then, viscous liquid material is placed on the battery film material at regular intervals. Based on the required material thickness, the thickness adjustment lifting motor 56 is activated. The thickness adjustment lifting motor 56 drives the thickness adjustment lifting screw 57 to rotate, causing the thickness adjustment lifting screw sleeve 55, the thickness adjustment seat 54, and the thickness adjustment guide rail seat 53 to rise and fall. This adjusts the distance between the rod 62 in the spreading mechanism 6 and the material on the battery film material, ultimately ensuring the material thickness meets the requirements. After the distance adjustment is completed, start the material leveling sliding linear motor 33 to drive the material leveling sliding frame 32, the flat film fixing seat 4 and the battery film material to move along the material leveling guide rail 2. During the movement, the cut 63 on the rod 62 scrapes the material flat, and at the same time, the arc surface on the other side of the cut 63 presses the material tightly. If a vibration motor is provided, the vibration motor can be started to make the rod 62 vibrate, further ensuring the material leveling and compaction effect and reducing material adhesion.

[0027] This utility model discloses a high-frequency and high-efficiency experimental battery material coating machine. By adsorbing the film material through negative pressure holes, the film material can be well fixed. Through the thickness adjustment mechanism and the material spreading mechanism, the material thickness can be produced as needed, and the material surface is flat, uniform and efficient.

[0028] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
