Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, specifically relating to a temperature control device for graphite anode materials. Background Technology

[0002] The background technology of temperature control devices for graphite anode materials stems from the temperature sensitivity requirements of lithium-ion batteries. In the early stages of battery manufacturing, the lack of precise temperature control led to unstable anode material structures, affecting battery performance and lifespan. With the development of the lithium battery industry, temperature control technology has gradually evolved from simple air cooling to liquid cooling, phase change materials, and precise temperature control using PID algorithms. This technology is applied in fields such as power batteries, energy storage systems, and consumer electronics, especially in scenarios such as high-rate fast charging and extremely cold environments, ensuring the lithium-ion intercalation efficiency and structural integrity of graphite anodes. It has also extended to emerging fields such as sodium-ion batteries and solid-state batteries, becoming a key technological support for improving battery safety and energy density.

[0003] In existing technologies, temperature control devices for graphite anode materials generally suffer from problems such as uneven temperature distribution, slow response, and high energy consumption. Traditional heating methods, such as resistance wire heating, are prone to local overheating, affecting the consistency of material performance. Air cooling or liquid cooling systems are difficult to achieve rapid and precise temperature adjustment. In addition, residues or contamination are easily generated during material loading and unloading. Manual adjustment methods cannot meet the precision requirements of industrial production. Especially when preparing high-purity anode materials, temperature fluctuations will directly affect the interlayer structure and lithium intercalation efficiency of graphite. Utility Model Content

[0024] 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. Example

[0025] Reference Figures 1-4 This is an embodiment of the present invention, which provides a temperature control device for graphite anode materials, comprising:

[0026] The base plate 101, the support frame 102 fixedly connected to the side wall of the base plate 101, the connecting shell 103 fixedly connected to the side wall of the base plate 101, the wiring hole 104 opened on the side wall of the connecting shell 103, the heating component 105 fixedly connected to the side wall of the support frame 102, the moving component 106 fixedly connected to the side wall of the base plate 101, and the loading component 107 fixedly connected to the side wall of the moving component 106;

[0027] The moving component 106 includes a fixed seat 106a fixedly connected to the side wall of the base plate 101, a slide rail 106b fixedly connected to the side wall of the fixed seat 106a, a linear motor 106c slidably connected to the surface of the slide rail 106b, and a moving seat 106d fixedly connected to the side wall of the linear motor 106c.

[0028] Specifically, the linear motor 106c ensures that the moving component 106 can move quickly, ensuring that the material can be quickly moved away from the heat source when heating the graphite anode material, thus ensuring the accuracy of temperature control during heating.

[0029] Furthermore, the heating assembly 105 includes a heating shell 105a fixedly connected to the side wall of the support frame 102, a fixing plate 105b fixedly connected to the side wall of the heating shell 105a, a limiting rod 105c fixedly connected to the inner wall of the heating shell 105a, a fixing cylinder 105d fixedly connected to the side wall of the fixing plate 105b, and a heating coil 105e wound on the surface of the fixing cylinder 105d, and terminals 105f welded to both ends of the heating coil 105e.

[0030] The loading assembly 107 includes a movable plate 107a fixedly connected to the side wall of the movable seat 106d, a drive motor 107b adapted to be installed on the side wall of the movable plate 107a, and a loading hopper 107c fixedly connected to the output end of the drive motor 107b. The loading assembly 107 also includes a fixed block 107d fixedly connected to the side wall of the movable plate 107a, a baffle 107e fixedly connected to the side wall of the fixed block 107d, and a scraper 107f fixedly connected to the side wall of the baffle 107e.

[0031] It should be noted that a mounting bracket 108 is fixedly connected to the side wall of the connecting housing 103, and an infrared camera 109 is fixedly connected to the side wall of the mounting bracket 108.

[0032] Among them, the infrared camera 109 adopts the FLIR E8 Pro thermal imager, which ensures accurate detection of the material heating temperature and allows for rapid material movement to adjust the temperature.

[0033] In use, material is placed in the loading hopper 107c, and the heating coil 105e is energized through the terminal 105f, starting the linear motor 106c. The linear motor 106c drives the moving base 106d to move, which in turn drives the moving plate 107a to move. The moving plate 107a pushes the loading hopper 107c into the fixed cylinder 105d. After the coil is energized, the fixed cylinder 105d is induction heated, and the temperature of the fixed cylinder 105d rises, thereby heating the material in the loading hopper 107c. Infrared... A linear camera monitors the temperature of the material. Once the temperature reaches the required level, the linear motor 106c returns to its original position, carrying the material out of the fixed cylinder 105d. During feeding, the drive motor 107b starts, driving the hopper 107c to move in a circular motion around the motor output end. The baffle 107e blocks the side wall of the hopper 107c to ensure that the material does not leak from the side. The scraper 107f scrapes the inner wall of the hopper 107c to ensure that there is no material residue in the hopper 107c, reducing losses.

[0034] In summary, the overall structural stability is achieved through the fixed connection between the base plate 101 and the support frame 102. The wiring hole 104 on the side wall of the connecting shell 103 provides a convenient channel for powering the heating coil 105e. In the heating assembly 105, the cooperation between the heating shell 105a and the fixing plate 105b defines the heating space. The limiting rod 105c ensures the precise alignment of the loading assembly 107. The fixing cylinder 105d and the heating coil 105e wound on its surface constitute the induction heating core. With the energization control of the terminal block 105f, efficient heating of the graphite negative electrode material is achieved. The moving assembly 1 06 The sliding connection between the slide rail 106b and the linear motor 106c drives the moving seat 106d to respond quickly, enabling the loading assembly 107 to move away from or near the heat source, thereby accurately controlling the material temperature; the loading hopper 107c achieves tilting and unloading through the drive motor 107b, and the combination of the baffle 107e and the scraper 107f prevents side leakage and thoroughly clears residual material, reducing losses; the infrared camera 109 monitors the temperature in real time and links with the moving assembly 106 to form a closed-loop temperature control system, ultimately achieving multiple improvements in heating efficiency, temperature accuracy, and material utilization.
