Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery production equipment, specifically a uniform and energy-saving baking device for lithium battery cells. Background Technology

[0002] Lithium-ion batteries, as an important energy storage device, are widely used in electric vehicles, consumer electronics, and energy storage power stations. The performance and quality of lithium-ion batteries directly affect the development of these applications, and the cell manufacturing process plays a crucial role in the performance and quality of lithium-ion batteries. Baking is a critical step in the lithium-ion battery cell production process, as it removes moisture and other impurities from the cells, improving their performance and stability. Therefore, the requirements for baking equipment are becoming increasingly stringent.

[0003] The technical problem to be solved by the patent publication number "CN220206195U" for "a lithium battery cell baking device" is to provide a lithium battery cell baking device. The solution adopted is as follows: the bottom end of the baking box is connected to the movable support through a second groove. The movable support is provided with a rotating device. The middle part of the rotating device is connected to the connecting plate through a rotating roller. The side end of the connecting plate is engaged with the tray. The inner end of the baking box is provided with an air outlet. The side end of the air outlet is connected to a hot air blower through a pipe. The output end of the electric push rod is connected to the push plate through a fastener.

[0004] In the aforementioned patent, lithium battery cells are placed in a baking oven, a movable support, a connecting plate, and a tray. Then, a hot air blower and a rotating device are activated. The rotation of the lithium battery cells allows for uniform heating, improving the efficiency of drying and thus enhancing the overall processing efficiency. However, during heating, the lithium battery cells are in direct contact with the rotating device, causing their temperature to rise too quickly and potentially damaging them. Furthermore, the confined space of the device may allow the lithium battery cells to release gases, especially under high temperatures or other specific conditions. If the baking device is too well-sealed, these gases cannot escape in time, leading to a gradual increase in internal pressure. When the pressure exceeds the device's tolerance limit, it could trigger a serious safety accident such as an explosion, posing a significant threat to personnel and equipment.

[0005] To address this issue, the present invention provides a uniform and energy-saving baking device for lithium battery cells. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a uniform and energy-saving baking device for lithium battery cells, which solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a uniform and energy-saving baking device for lithium battery cells, comprising a heating component, the heating component comprising a right working chamber, a top hole being formed at the center of the upper surface of the working chamber, a side hole being formed at the center of the left side surface of the working chamber, a rotating component being arranged above the working chamber, the rotating component comprising a rotating shaft, a second motor being fixedly connected to the top end of the rotating shaft, a placement plate being fixedly connected to the side surface of the rotating shaft, and the top side surface of the rotating shaft being rotatably connected to the inner wall of the top hole.

[0008] Furthermore, a second support frame is fixedly connected to the upper surface of the second motor, the bottom end of the second support frame is fixedly connected to the upper surface of the working chamber, a rotating cylinder is rotatably connected to the bottom side surface of the rotating shaft, the lower surface of the rotating cylinder is fixedly connected to the center of the bottom inner wall of the working chamber, and a partition is fixedly connected to the upper surface of the placement tray.

[0009] By adopting the above technical solution, the lithium battery cells are placed on the upper surface of the placement tray, avoiding direct contact between the cells and the inner wall of the oven during baking, which could lead to localized overheating and damage to the lithium battery cells. Instead, the heat is indirectly transferred to all parts of the cells through the air around them, achieving the beneficial effects of more uniform heating of the lithium battery cells and protecting their condition.

[0010] Furthermore, a blower assembly is provided on the left side of the working chamber. The blower assembly includes a first support frame, a first motor is fixedly connected to the inner surface of the first support frame, the output shaft side surface of the first motor is rotatably connected to the inner wall of the side hole, and the right side surface of the first support frame is fixedly connected to the left side surface of the working chamber.

[0011] By adopting the above technical solution, the first motor drives the fan to rotate, and the air generated by the fan blows the heat generated by the circular electric heating grid into the working chamber, thus extending the service life of the device.

[0012] Furthermore, a fan is fixedly connected to the output shaft of the first motor.

[0013] By adopting the above technical solution, the air volume generated is made more stable through the fan and the first motor.

[0014] Furthermore, a connecting frame is fixedly connected to one end of the left inner wall of the working chamber, and a circular electric heating mesh is fixedly connected to the other end of the connecting frame.

[0015] By adopting the above technical solution, the distance between the circular electric heating mesh and the fan is increased by using a connecting frame to avoid collision between the two.

[0016] Furthermore, a baffle is fixedly connected to the front surface of the top of the working chamber, an extension plate is fixedly connected to the front surface of the bottom of the working chamber, a glass observation plate is slidably connected between the baffle and the working chamber, and a ventilation hole is opened on the right side surface of the working chamber.

[0017] By adopting the above technical solution, the air generated by the fan and the heat generated by the circular electric heating grid can better remove moisture and impurities from the lithium battery cells. The ventilation holes prevent the internal pressure of the device from gradually increasing if the baking device is too well sealed, thus avoiding the inability of heated gas from the lithium battery cells to be discharged in time. This achieves the beneficial effects of improving the drying efficiency of the device and ensuring work safety.

Instead, the heat is indirectly transferred to all parts of the cell through the air around it, achieving a more uniform heating effect and protecting the condition of the lithium battery cells.

[0021] 2. This uniform and energy-saving baking device for lithium battery cells uses the air generated by the fan and the heat generated by the circular electric heating grid to better remove moisture and impurities from the lithium battery cells. The ventilation holes prevent the internal pressure of the device from gradually increasing if the baking device is too well sealed, thus improving the drying efficiency and ensuring work safety.
