Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery casing processing technology, specifically a gradient curing device for battery top cover edge wrapping. Background Technology
[0002] With the rapid development of the new energy vehicle and consumer electronics industries, lithium batteries, as core power sources and energy storage units, have received unprecedented attention for their safety and sealing. The battery cover, as a key sealing component of the battery pack, is typically joined to the casing via an edge-wrapping process. The adhesive or coating at the edge must be heated and cured to form a long-lasting and reliable seal.
[0003] Currently, the industry primarily uses integrated heating ovens or fixed hot air guns to cure the edge banding of battery covers. These traditional methods have significant drawbacks: First, integrated heating makes it difficult to uniformly heat the complex edge banding structure, easily leading to localized overheating or underheating, resulting in insufficient or over-curing and affecting sealing reliability; second, one-time integrated heating subjectes the material to enormous thermal stress instantly, easily causing edge deformation, substrate damage, or changes in internal molecular structure, creating potential safety hazards; finally, fixed heating equipment cannot achieve targeted gradient temperature control, making it difficult to meet the requirements of refined and intelligent curing processes in high-end battery manufacturing.
[0004] Therefore, there is an urgent need for a dedicated curing device that can achieve precise temperature control, gradient heating, and a high degree of automation to solve the above-mentioned technical pain points and ensure high quality, high consistency, and high reliability of the battery cover edge curing.

[0013] (III) Beneficial Effects
[0014] This invention provides a gradient curing device for the edge wrapping of a battery cover. It has the following beneficial effects:
[0015] 1. This solution sets up a sliding base that can move around the edge of the battery cover, and integrates an angle-adjustable hot air blower and an infrared heater with a thermal sensor on it. This allows the hot air preheating and infrared precise heating to work together, and the heating strategy can be dynamically adjusted according to real-time temperature feedback. This achieves gradient temperature control and efficient and uniform curing of the edge material from the inside to the outside or from the key area to the secondary area, thereby improving the curing quality and avoiding thermal stress damage.

[0022] This utility model embodiment provides a battery cover edge-sealing gradient curing device, such as... Figure 1-4 As shown, it includes a curing stage 11, a slide rail 12, a battery cover 13, a slider 14, a first slot 15, a first drive shaft 16, a first drive wheel 17, a sliding base 18, a rotating slot 19, a rotating shaft 20, a hot air blower 21, a second slot 22, a third slot 23, a second drive shaft 24, a second drive gear 25, an infrared base 26, a thermal sensor 27, and an infrared heater 28.
[0023] like Figure 1-4 As shown, a slide rail 12 is provided on the curing table 11, and the battery cover 13 is clamped on the curing table 11. The slide rail 12 is arranged around the battery cover 13. A slider 14 is slidably connected inside the battery cover 13. A sliding base 18 is fixedly connected to the slider 14. A hot air blower 21 is rotatably arranged on the side of the sliding base 18 near the battery cover 13. An infrared component is fixedly connected to the end of the sliding base 18 away from the slider 14.
[0024] The sliding base 18 has a rotating slot 19 on the side near the hot air blower 21. The hot air blower 21 is fixedly connected to a rotating shaft 20. The rotating shaft 20 is rotatably connected to the rotating slot 19. The rotating shaft 20 is a semi-cylinder. The shape and size of the rotating slot 19 are matched with those of the rotating shaft 20.
[0025] The rotating slot 19 is also provided with a second slot 22, and the rotating shaft 20 is provided with a third slot 23 on the side near the sliding base 18. Gear teeth are provided in the third slot 23. A second drive shaft 24 is fixedly connected in the second slot 22. A second drive gear 25 is rotatably connected to the second drive shaft 24. The second drive gear 25 meshes with the third slot 23.
[0026] Both sides of the slider 14 are provided with a first slot 15. A first drive shaft 16 is fixedly connected in the first slot 15. A first drive wheel 17 is rotatably connected to the first drive shaft 16. The first drive wheel 17 is rolledly connected to the slide rail 12.
[0027] The infrared component includes an infrared base 26, a thermal sensor 27, and an infrared heater 28. The infrared base 26 is fixedly connected to the sliding base 18. An inclined surface is provided at the end of the infrared base 26 away from the sliding base 18. The thermal sensor 27 is fixedly connected to the side of the infrared base 26 near the battery cover 13. The infrared heater 28 is fixedly connected to the inclined surface of the infrared base 26.
[0028] When this solution performs gradient curing of the battery cover edge, firstly, the operator firmly clamps the battery cover 13 onto the curing table 11, ensuring that the slide rail 12 is set around the edge area of the battery cover 13. Then, the control system of the device is activated, and the first drive shaft 16 drives the first drive wheel 17 to roll on the slide rail 12, causing the slider 14 to slide along the slide rail 12, thereby moving the sliding base 18 and its hot air blower 21 and infrared components around the battery cover 13. At the same time, the second drive shaft 24 engages with the third slot 23 on the rotating shaft 20 through the second drive gear 25, driving the hot air blower 21 to rotate in the rotating slot 19, adjusting the hot air outlet angle, and blowing hot air in a directional manner to preheat and initially cure the edge.
[0029] Then, the thermal sensor 27 on the infrared base 26 monitors the temperature of the edge area of the battery cover 13 in real time and feeds the data back to the control system. The control system adjusts the heating intensity of the infrared heater 28 according to the preset gradient curing curve, while continuing to control the moving speed of the sliding base 18 and the rotation angle of the hot air blower 21 to achieve differentiated heating of different areas, ensuring that the edge is cured gradually from the center to the edge, and avoiding thermal stress concentration.
[0030] Finally, when the thermal sensor 27 detects that the entire edge-sealing area has reached the required curing temperature and remains stable, the control system automatically stops the operation of the hot air blower 21 and the infrared heater 28, the first drive shaft 16 rotates in the opposite direction, causing the slider 14 to return to its initial position, and the operator removes the battery cover 13 that has completed gradient curing, thus completing the entire process.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
