Description

Technical Field

[0001] This utility model belongs to the field of lithium-ion battery manufacturing technology, specifically relating to a lithium battery binder coating temperature control box with a uniform airflow distribution structure. Background Technology

[0002] In the manufacturing process of lithium batteries, the coating process of the electrode sheets is one of the key steps, and its quality directly affects the battery's capacity, cycle life, and safety. After the binder is coated, it needs to be dried and cured in a temperature-controlled chamber. This process requires hot air to be applied evenly to the electrode surface to achieve stable solvent evaporation and dense coating formation. However, traditional temperature-controlled chambers often use fixed nozzles or centralized air supply methods, and the airflow distribution is easily affected by the chamber structure and electrode layout, resulting in inconsistent drying rates in different areas. In addition, fluctuations in ambient temperature and humidity and unreasonable air duct design can also easily cause airflow deviation, eddies, or dead zones, resulting in problems such as changes in coating thickness, edge warping, or decreased adhesion.

[0003] In existing technologies, traditional lithium battery coating temperature control boxes often use fixed air ducts or overall air supply structures, which may make it difficult to adjust the airflow direction. This can easily lead to uneven airflow distribution on the electrode surface, resulting in inconsistent coating drying rates and problems such as edge cracking or solvent residue in the central area.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figures 1-4 This embodiment of the present invention provides a lithium battery binder coating temperature control box with an airflow uniform distribution structure, comprising:

[0028] The supporting mechanism 100 includes a fixed cylinder 101, multiple support rods 102 fixed to the inner wall of the fixed cylinder 101 and arranged in a ring array, a fixed plate 103 fixedly connected to the inner end of each support rod 102, and a fixed frame 104 fixedly installed on the outer periphery of the fixed cylinder 101.

[0029] The adjustment mechanism 200 includes a knob 201 disposed on one side of the fixed frame 104, a connecting rod 202 fixedly connected to the knob 201 at one end, an adjustment rod 203 fixed to the outer surface of the connecting rod 202, a guide rod 204 rotatably connected to the adjustment rod 203, a ventilation component 205 for controlling the wind speed inside the fixed cylinder 101, and a limiting component 206 used in conjunction with the ventilation component 205.

[0030] The ventilation assembly 205 includes a fixed rod 205a fixedly connected to the adjusting rod 203, a fan blade 205b fixed to the free end of the fixed rod 205a, and a movable rod 205c fixed to the outer surface of the fixed plate 103 and hinged to the fan blade 205b.

[0031] When it is necessary to adjust the ventilation angle inside the fixed cylinder 101, the knob 201 can be rotated. The knob 201 drives the connecting rod 202 fixedly connected to it to rotate synchronously. The rotation of the connecting rod 202 drives the adjusting rod 203 fixedly connected to it to move. The adjusting rod 203 drives the guide rod 204 to rotate together, thereby pushing the fixed rod 205a to rotate around the sealed bearing, realizing the adjustment of the swing angle of the fan blade 205b, thereby changing the airflow direction and meeting the air volume distribution requirements under different working conditions.

[0032] Specifically, the limiting assembly 206 includes a limiting wheel 206a fixedly installed on the outer surface of the connecting rod 202, a fixing block 206b fixedly installed on the outer surface of the fixing frame 104, a limiting block 206c rotatably connected to the fixing block 206b and used in conjunction with the limiting wheel 206a, a spring 206d fixedly connected to the limiting block 206c, and a paddle 206e fixedly connected to the limiting block 206c.

[0033] When the angle of the fan blade 205b needs to be adjusted, first press the lever 206e. The lever 206e drives the limiting block 206c, which is fixedly connected to it, to move. The limiting block 206c applies pressure to the spring 206d and disengages from the locking state with the outer circumferential positioning teeth of the limiting wheel 206a, thus unlocking. Then, rotate the knob 201 to adjust the angle. After the adjustment is completed, release the lever 206e. The spring 206d returns to its original position under the action of elasticity, pushing the limiting block 206c to re-lock between the adjacent positioning teeth of the limiting wheel 206a, thus achieving automatic locking of the angle position.

[0034] Furthermore, the support rods 102 are evenly distributed along the inner wall of the fixed cylinder 101 and are bolted to the fixed cylinder 101 and the fixed plate 103 respectively.

[0035] Furthermore, the connecting rod 202 is rotatably inserted into the fixed frame 104, with one end connected to the knob 201 and the other end connected to the adjusting rod 203. A bearing or bushing is provided between the connecting rod 202 and the fixed frame 104.

[0036] Furthermore, the adjusting rods 203 and guide rods 204 are evenly distributed along the outer periphery of the fixed cylinder 101. One end of each adjusting rod 203 is fixedly connected to the connecting rod 202, and the other end is fixedly connected to the fixed rod 205a.

[0037] Preferably, one end of the fixing rod 205a is fixedly connected to the adjusting rod 203, and the other end extends into the inside of the fixing cylinder 101 and is fixedly connected to the fan blade 205b. A sealed bearing is provided at the penetration point between the fixing rod 205a and the side wall of the fixing cylinder 101.

[0038] It should be noted that the outer circumference of the limiting wheel 206a is provided with multiple positioning teeth, and the limiting block 206c is engaged between adjacent positioning teeth under the elastic force of the spring 206d to realize multi-level angular positioning of the knob 201. The other end of the spring 206d is fixedly connected to the fixed frame 104.

[0039] In use, when it is necessary to adjust the ventilation angle inside the temperature control box to optimize airflow distribution, the operator first presses the lever 206e. The lever 206e drives the limiting block 206c, which is fixedly connected to it, to rotate around the fixed block 206b. This causes the limiting block 206c to apply pressure to the spring 206d and compress its stored energy. At the same time, the limiting block 206c disengages from the outer circumferential positioning teeth of the limiting wheel 206a, achieving axial unlocking. Subsequently, the knob 201 is rotated. The knob 201 drives the connecting rod 202, which is fixedly connected to it, to rotate synchronously. The connecting rod 202 drives multiple adjusting rods 203 that are evenly distributed circumferentially. Each adjusting rod 203 moves through a guide rod 204. The rotating connection forms a linkage mechanism, which pushes the fixed rod 205a, which is fixedly connected to it, to rotate around the sealed bearing, thereby driving the fan blade 205b, which extends into the fixed cylinder 101, to swing synchronously, so as to realize the continuous adjustment of the ventilation angle. During this process, the movable rod 205c is hinged to the fan blade 205b to limit the swing range of the fan blade and prevent damage from over-extension. After the adjustment is completed, the lever 206e is released, the spring 206d releases its stored energy, and under the action of elastic force, pushes the limit block 206c to reset, so that it is re-engaged between the adjacent positioning teeth of the limit wheel 206a, realizing the automatic locking of the knob 201 at the new angle position, ensuring that the airflow state is stable and reliable during operation.

[0040] In summary, by setting up an adjustable-angle fan blade 205b assembly and a linkage transmission structure, precise control of the airflow direction inside the temperature control box can be achieved, effectively improving the uniformity of wind speed distribution and avoiding uneven coating drying caused by excessively strong or weak local wind speeds. Combined with a multi-stage positioning and automatic locking limit structure, the adjusted state is ensured to be stable and reliable, preventing deviation during operation, reducing the risk of defects such as edge cracking and solvent residue, and improving coating quality and product yield.
