Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to a dryer for button battery production. Background Technology

[0002] Button batteries, also known as coin cells, are batteries that are shaped like a small button. Due to their small size, button batteries are widely used in various microelectronic products.

[0003] Dryers are typically used in the production of button batteries to dry the packaged batteries, removing excess moisture and ensuring battery stability. The drying temperature and time need to be adjusted according to the battery type.

[0004] An existing button battery processing and drying device, patent application number 202321829014.5, uses a drying equipment setup to rotate a fan blade and simultaneously activate a heating wire. The air blown down by the fan blade is heated by the heating wire, thus drying the battery. A vibration component is used during the drying process to move a screen plate up and down via the output end of an electric telescopic rod. This vibrates and breaks up the batteries on the screen plate, increasing the contact area and allowing excess water to flow down through the holes on the screen plate, achieving a rapid drying effect.

[0005] As mentioned above, existing dryers used in button cell production typically include a sieve plate to hold the button cells, which achieves rapid drying through up-and-down vibration. However, the internal structure of button cells is relatively delicate, and up-and-down vibration may cause uneven mixing of the chemical substances inside the cell, or cause displacement or deformation of the electrode materials, thereby affecting the battery's electrical performance. Furthermore, severe vibration may even damage the internal separator or protective layer of the cell, causing internal short circuits or electrolyte leakage, increasing the risk of battery explosion or fire.

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0032] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0033] This utility model provides a dryer for button battery production, such as... Figures 1 to 5As shown, the device includes a drying chamber 1, a drying device 2 is installed on the inner wall of the drying chamber 1, and a rotating assembly is installed inside the drying chamber 1. The rotating assembly includes a drive component 31, a placement frame 32, and a limiting cover 33. The limiting cover 33 is detachably connected to the placement frame 32. The placement frame 32 includes a receiving groove 321 for placing button batteries. The limiting cover 33 covers the receiving groove 321. The drive component 31 penetrates one side wall of the drying chamber 1, and the placement frame 32 is detachably connected to the drive component 31.

[0034] This application provides a closed environment through a drying chamber 1, and a drying device 2 provides the heat required for drying. A rotating assembly, driven by a drive unit 31, rotates the placement frame 32, ensuring uniform heating of the button battery during the drying process. The design of the placement frame 32 and the limiting cover 33 ensures that the button battery is stably placed in the receiving slot 321 during drying, effectively preventing damage to the button battery. The detachable connection between the drive unit 31 and the placement frame 32 facilitates maintenance and replacement of the placement frame 32.

[0035] In this embodiment, the drying device 2 is an electric heating wire. It should be noted that the electric heating wire is existing technology, and those skilled in the art should be clear about its structure, principle and usage, etc., which will not be described in detail here.

[0036] In this embodiment, the driving component 31 includes a motor 311 and a transmission shaft 312. A transmission arm 322 is provided on the side wall of the placement frame 32, and the transmission arm 322 is sleeved on the outer wall of the transmission shaft 312. In this embodiment, the driving component 31 can stably and efficiently drive the placement frame 32 to rotate, achieving uniform heating and rapid drying of the button battery during the drying process. In other embodiments, the sleeve hole of the transmission arm 322 and the outer wall of the transmission shaft 312 can be connected by an interference fit or a keyway to ensure that the transmission arm 322 can be firmly sleeved on the transmission shaft 312, preventing loosening or falling off during rotation.

[0037] In this embodiment, the placement frame 32 and the limiting cover 33 are provided with a plurality of through holes 323. The through holes 323 are interconnected with the receiving groove 321. Hot air enters the receiving groove 321 through the through holes 323 and is evenly distributed around the button battery, ensuring that each button battery can be fully dried. This can effectively improve the uniformity and efficiency of the button battery in the drying process and avoid uneven drying caused by poor air circulation.

[0038] In other embodiments, the through-hole 323 can take various forms, such as circular, square, or other geometric shapes, to adapt to different design requirements and manufacturing processes. The number and distribution of the through-hole 323 can be adjusted as needed to ensure that hot air can evenly cover the entire receiving groove 321. It should be noted that the size of the through-hole 323 must be smaller than the size of the button cell.

[0039] In this embodiment, the limiting cover 33 includes a fixing part 331 and an anti-detachment part 332 fixedly connected to the fixing part 331. The limiting cover 33 fits into the placement frame 32 through the anti-detachment part 332 to ensure that the limiting cover 33 can be firmly fixed on the placement frame 32, preventing the button battery from falling off or shifting during the drying process, thereby avoiding damage to the internal structure of the battery and ensuring the stability and safety of the battery.

[0040] The annular structure of the anti-detachment part 332 can be implemented in various ways: the anti-detachment part 332 is fitted into the receiving groove 321; or, the anti-detachment part 332 is sleeved on the outer wall of the placement frame 32; or, the anti-detachment part 332 is set as a double-layer annular structure to form a fitting groove, and the placement frame 32 is fitted into the fitting groove.

[0041] In this embodiment, the limiting cover 33 also includes a fixing pin 333, which passes through the anti-detachment part 332 and the placement frame 32, and firmly connects the anti-detachment part 332 and the placement frame 32 together. This prevents the placement frame 32 and the anti-detachment part 332 from separating due to vibration or other external forces during the drying process, thereby ensuring the stability of the button battery during the drying process. This effectively avoids damage to the internal structure of the battery due to vibration during the drying process, and ensures the electrical performance and safety of the battery.

[0042] In other embodiments, the fixing pin 333 may be made of metal to ensure sufficient strength and durability. The fixing pin 333 may be fixed to the anti-detachment part 332 and the placement frame 32 by means of threaded connection, snap-fit ​​connection and other methods.

[0043] In this embodiment, an elastic element 334 and a limiting plate 335 are sequentially arranged on the side of the fixing part 331 facing the placement frame 32. The elastic element 334 is abutting and connected between the fixing part 331 and the limiting plate 335, and the limiting plate 335 abuts against the button battery. In this embodiment, through the cooperation of the fixing part 331, the elastic element 334 and the limiting plate 335, the elasticity of the elastic element 334 is used to press the limiting plate 335 onto the button battery, thereby achieving effective fixation of the button battery, preventing it from moving during the drying process, and thus preventing damage to the internal structure of the battery and the impact on its electrical performance.

[0044] In other embodiments, the elastic element 334 can be made of materials with elastic properties such as springs or rubber pads, and the limiting plate 335 can be made of materials such as metal plates or plastic plates. Their shape and size can be designed according to the specific specifications of the button battery. The specific structure and material selection of the elastic element 334 and the limiting plate 335 can be adjusted according to actual needs to achieve the best fixing effect. For example, the spring constant can be selected based on the battery weight and vibration during the drying process. The thickness and stiffness of the limiting plate 335 can also be designed according to the battery size and the mechanical requirements during the drying process.

[0045] In this embodiment, a control panel 11 and control buttons 12 are provided on the outside of the drying chamber 1.

[0049] This utility model provides a dryer for button battery production. In use, the button batteries are first placed into the receiving slot 321 of the placement frame 32, and then the upper limit cover 33 is placed on top, ensuring a tight fit between the upper limit cover 33 and the placement frame 32. The placement frame 32 is then mounted on the drive shaft 312 via the drive arm 322. Next, the drying equipment 2 and motor 311 are started via the control button 12. The motor 311 drives the drive shaft 312 to rotate, and the drive shaft 312 provides rotational power to the placement frame 32 via the drive arm 322, causing the placement frame 32 to rotate. This ensures the button batteries are evenly heated within the drying chamber 1, achieving the drying effect. Because the placement frame 32 and the upper limit cover 33 are provided with through holes 323, hot air can evenly pass through the through holes 323 to dry the button batteries.
