Description

Technical Field

[0001] This utility model relates to the field of torsion battery packaging, specifically a feeding structure for a torsion battery packaging machine. Background Technology

[0002] Torsion batteries are ultra-thin energy storage devices that utilize flexible materials and a twistable structure. Through the synergistic effect of internal elastic components and adaptive electrolytes, the battery can still provide stable power supply under extreme deformations such as repeated bending, stretching, or torsion. They are mainly used in electronic fields such as smart wearables, foldable phones, and implantable medical devices, and combine high energy density with mechanical durability. Torsion battery packaging refers to the customized packaging of torsion batteries by using flexible packaging materials and extensible structural designs, combined with precise automated processes, to ensure that the core components of the battery are protected from mechanical stress and damage from the external environment.

[0003] In current twisted battery packaging technology, although the feeding device and battery packaging mechanism have achieved a high degree of automation and integration, and possess mature orientation positioning and precision packaging capabilities, there are still significant technical bottlenecks in the feeding process. Because twisted battery cells must maintain a strictly horizontal spatial posture before packaging to ensure the alignment accuracy of the electrode plates and the packaging mold, existing systems have not yet implemented automated posture correction functions. This results in the feeding process still relying on manual intervention—operators must first tilt batches of battery cells into the storage bin in a non-directional manner, and then manually visually adjust the horizontal placement of each battery cell before transferring them to the conveyor belt. This process not only significantly increases labor costs and operating time, but also leads to increased equipment start-up and shutdown frequency and fluctuations in packaging yield due to random errors in manual operation. Furthermore, there is a risk of battery structural damage caused by contact operation. Based on this, this invention designs a feeding structure for a twisted battery packaging machine to solve the above problems. Utility Model Content

The first brush 304 and the second brush 306 are arranged symmetrically with the first brush 304 and the second brush 306. The leveling mechanism 4 includes an inclined storage net 401. The front and rear ends of the storage net 401 are fixed with limiting plates 402, and the left end is fixed with a mounting plate 403. The mounting plate 403 is fixed with a vibration motor 404. The lower end is provided with a first spring body 405 and its corresponding first spring seat 406.

[0029] Drive system: The first drive motor 309 synchronously drives three sets of first rotating shafts 303 through the first transmission belt 307, and the second drive motor 310 drives three sets of second rotating shafts 305 through the second transmission belt 308.

[0030] Material guiding channel: The internal groove track of the material guiding bin 302 is CNC machined and has a cross-section that is elliptical to fit the torsion battery. The end of the track extends 10mm to the upper surface of the storage net 401.

Inside the guide bin 302, three sets of first rotating shafts 303 drive the first brush 304 and three sets of second rotating shafts 305 drive the second brush 306 to rotate, forming a dynamic combing channel, effectively transferring the batteries and forcing the randomly stacked battery cells to move directionally along the slot track; the combed battery cells then fall into the inclined placement net 401. The vibration motor 404 transmits high-frequency micro-amplitude vibration at a frequency of 50-60Hz through the mounting plate 403. With the elastic support of the first spring body 405 and the second spring body 407, the batteries complete planar posture self-correction within the channel formed by the limiting plate 402; finally, the corrected batteries slide along the inclined surface of the placement net 401 to the conveyor belt 2, maintaining a horizontal state as they enter the subsequent packaging station.
