Description

Technical Field

[0001] This utility model relates to the field of lithium battery separator technology, and in particular to a novel hot air-assisted drying mechanism for a lithium battery separator coating machine. Background Technology

[0002] Lithium-ion battery films are an important component of lithium-ion batteries, mainly consisting of two parts: the separator and the packaging material. The separator is located between the positive and negative electrodes, used to isolate them and prevent short circuits, while ensuring that lithium ions can pass through the microporous channels normally during charging and discharging to guarantee normal battery operation. Its performance significantly affects key indicators such as the battery's internal resistance, capacity, cycle performance, charge / discharge current density, and safety. Typically, after coating the separator, residual solvents and water need to be dried.

[0003] Existing lithium battery coating methods generally use roller transfer, but this method is only suitable for coatings with low viscosity and low coating amount, and has a narrow applicability. In addition, the heating of the film after the existing lithium battery coating is generally done on the bottom of the film, but the solvent and water on the surface of the film dry slowly, resulting in poor drying effect. Therefore, a new hot air-assisted drying mechanism is needed for lithium battery separator coating machines. Utility Model Content

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the lithium battery separator is placed on the worktable and held in place by the moving mechanism. Then, the rotating rod is rotated to add coating solvent into the storage box. The motor is started, and the motor drives the screw to rotate. The rotation of the screw drives the coating machine to move, and the movement of the coating machine can uniformly coat the lithium battery separator, resulting in a good coating effect.

[0014] In this invention, through the structural design of the auxiliary drying mechanism, the heating block can be turned on to heat and dry the lithium battery separator during the coating process. The heating plate is turned on, and then the motor is started. The motor drives the fan blades to rotate, and the fan blades generate wind to blow the heat generated by the heating plate onto the upper surface of the lithium battery separator. Then, the drying box is moved by the coating machine. In this way, the drying time of the solvent and water on the upper surface of the lithium battery separator can be reduced, and the drying efficiency can be improved. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example:

[0022] like Figure 1-4 As shown, this embodiment provides a novel hot air-assisted drying mechanism for a lithium battery separator coating machine, including a support plate 1, a slide plate 2 fixedly installed on the support plate 1, a worktable 3 fixedly installed on the inner side of the slide plate 2, a lithium battery separator 4 disposed on the worktable 3, a coating machine 5 disposed on the lithium battery separator 4, a moving mechanism 6 disposed at the bottom of the worktable 3, the coating machine 5 fixedly installed on the moving mechanism 6, a vacuum adsorption port 7 disposed on the worktable 3, a heating block 8 disposed inside the worktable 3, a storage box 9 fixedly installed on the coating machine 5, a rotating rod 10 threadedly installed inside the storage box 9, and an auxiliary drying mechanism 11 disposed on one side of the coating machine 5;

[0023] The lithium battery separator 4 is placed on the workbench 3 and adsorbed through the vacuum adsorption port 7. Then, the rotating rod 10 is rotated to remove the rotating rod 10 and add coating solvent into the storage box 9. The driving moving mechanism 6 can drive the coating machine 5 to move and coat the lithium battery separator 4. The heating block 8 can be turned on to heat and dry the lithium battery separator 4. Then, the auxiliary drying mechanism 11 can be driven to assist the heating block 8 in accelerating the drying of solvent and water on the upper surface of the lithium battery separator 4.

[0024] In this embodiment of the utility model, specifically, the moving mechanism 6 includes a support block 61 fixedly installed at the bottom of the workbench 3, a screw 62 rotatably installed in the support block 61, a sliding groove 63 opened on the support plate 1, a screw 64 slidably installed in the sliding groove 63, the screw 64 threadedly sleeved on the screw 62, a connecting frame 65 fixedly installed on the screw 64, the connecting frame 65 slidably installed on the slide plate 2, and the coating machine 5 fixedly installed at the other end of the connecting frame 65;

[0025] To facilitate the coating of the lithium battery separator 4, the lithium battery separator 4 is placed on the workbench 3 and adsorbed through the vacuum adsorption port 7. Then, the rotating rod 10 is rotated to remove the rotating rod 10 and add the coating solvent into the storage box 9. The screw 62 is rotated, and the rotation of the screw 62 drives the screw 64 to move in the slide groove 63. The movement of the screw 64 drives the connecting frame 65 to move, and the movement of the connecting frame 65 drives the coating machine 5 to move. The movement of the coating machine 5 can uniformly coat the lithium battery separator 4.

[0026] In this embodiment of the utility model, a motor 66 is fixedly installed at the bottom of the workbench 3, a screw 62 is fixedly installed at the output end of the motor 66, a sliding sleeve 67 is fixedly installed at the bottom of the workbench 3, the screw 62 is rotatably installed in the sliding sleeve 67, and a limit block 68 is provided on one side of the support block 61, the limit block 68 is fixedly installed on the screw 62.

[0027] The motor 66 provides power to the screw 62, causing it to rotate. The sliding sleeve 67 restricts the position of the screw 62, ensuring that it rotates only within the sliding sleeve 67. The limiting block 68 restricts the position of the screw 62, preventing it from moving out of the support block 61.

[0028] In this embodiment of the utility model, specifically, the auxiliary drying mechanism 11 includes a drying box 111 fixedly installed on one side of the coating machine 5, a heating plate 112 fixedly installed at the bottom of the drying box 111, a motor 113 fixedly installed on the upper surface of the drying box 111, a battery pack 114 fixedly installed inside the motor 113, a rotating shaft 115 fixedly installed at the output end of the motor 113, a fan blade shaft 116 fixedly installed on the rotating shaft 115, and a fan blade 117 fixedly installed on the fan blade shaft 116.

[0029] To accelerate the drying of solvent and water on the lithium battery separator 4, the heating plate 112 is turned on, and then the motor 113 is started. The motor 113 drives the rotating shaft 115 to rotate, which in turn drives the fan blade shaft 116 to rotate. The fan blade shaft 116 then drives the fan blade 117 to rotate, and the fan blade 117 generates airflow that blows onto the heating plate 112. The heat generated by the heating plate 112 is then blown onto the upper surface of the lithium battery separator 4. The drying box 111 is then moved by the coating machine 5, which accelerates the drying of solvent and water on the lithium battery separator 4.

[0030] Working principle: During use, the lithium battery separator 4 is placed on the worktable 3 and adsorbed through the vacuum adsorption port 7. Then, the rotating rod 10 is rotated to remove it, and coating solvent is added to the storage box 9. The motor 66 is started, and the motor 66 drives the screw 62 to rotate. The rotation of the screw 62 drives the screw strip 64 to move in the slide groove 63. The movement of the screw strip 64 drives the connecting frame 65 to move, and the movement of the connecting frame 65 drives the coating machine 5 to move. The movement of the coating machine 5 can uniformly coat the lithium battery separator 4, resulting in a good coating effect. During the coating process, the heating block 8 is turned on. The lithium battery separator 4 can be heated and dried. The heating plate 112 is turned on, and the motor 113 is started. The motor 113 drives the rotating shaft 115 to rotate, which in turn drives the fan blade shaft 116 to rotate. The fan blade shaft 116 drives the fan blade 117 to rotate, and the fan blade 117 generates airflow that blows onto the heating plate 112. The heat generated by the heating plate 112 is then blown onto the upper surface of the lithium battery separator 4. The drying box 111 is then moved by the coating machine 5. This reduces the drying time of the solvent and water on the upper surface of the lithium battery separator 4 and improves the drying efficiency.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
