Description

Technical Field

[0001] This invention relates to the technical field of dust removal equipment for stacked lithium batteries, specifically a fully automatic ultrasonic dust removal device for the positive and negative electrode sheets of new energy batteries. Background Technology

[0002] Lithium-ion batteries are a new generation of high-performance, green, and high-energy batteries, and have become a key focus of high-tech development. Lithium-ion batteries possess the following characteristics: high voltage, high capacity, low power consumption, no memory effect, no pollution, small size, low internal resistance, low self-discharge, and high cycle life. Due to these characteristics, lithium-ion batteries have been applied in numerous civilian and military fields, including new energy vehicles, mobile phones, laptops, camcorders, and digital cameras. The lithium battery electrode dust collector is a crucial component of lithium battery production equipment, significantly impacting battery quality and lifespan. The design of the lithium battery electrode dust collector is a critical factor affecting battery production quality. Within the dust collector, the mechanism for die-cutting soft-pack lithium batteries is a particularly critical component.

[0003] Existing technologies typically employ brush rollers or air knives for dust removal in their dust collection mechanisms, resulting in unsatisfactory dust removal performance. Incomplete dust removal fails to effectively clean even highly adhesive dust particles. The cleanliness of the positive and negative electrode sheets has a crucial impact on battery performance. Traditional dust removal methods, such as brush cleaning and negative pressure suction, have many shortcomings, including the tendency for brushes to accumulate dust, scratch the electrode surface, and the inability to thoroughly remove fine particles. However, due to the high cleanliness requirements for the electrode surface and the need to avoid damaging it during dust removal, there is an urgent need for a fully automated ultrasonic dust removal device for the positive and negative electrode sheets of new energy batteries. Summary of the Invention

[0017] Compared with the prior art, the present invention provides a fully automatic ultrasonic dust removal device for positive and negative electrode sheets of new energy batteries, which has the following beneficial effects:

[0018] 1. This fully automatic ultrasonic dust removal equipment for positive and negative electrode sheets of new energy batteries uses front and back brush dust removal components to initially remove large particles and dust from the electrode surface. By setting up front and back ultrasonic dust removal heads and components, the vibration effect of ultrasound is used to further clean the surface of tiny particles and deposits. Front and back electrostatic roller adsorption components adsorb and remove electrostatic dust and tiny particles from the electrode surface, ensuring thorough cleaning. The combination of multiple dust removal technologies improves the adaptability and stability of the equipment. The front and back magnetic rod iron removal components remove ferromagnetic impurities from the electrode, further enhancing the stability and reliability of the equipment. The automated and continuous dust removal process reduces manual intervention, improves production efficiency, and makes the entire dust removal process more efficient and faster, thereby improving overall production efficiency. It features good dust removal effect, easy disassembly, and simple installation, achieving advantages such as strong cleaning ability, high efficiency, and compact structure.

[0019] 2. This fully automatic ultrasonic dust removal equipment for positive and negative electrode sheets of new energy batteries utilizes the characteristics of upper and lower vacuum conveyor belts to place multiple sheets on the vacuum belts for dust removal from both the top and bottom. The two vacuum conveyor belts can work simultaneously to perform double-sided dust removal on the electrode sheets, greatly shortening the dust removal time and improving the dust removal efficiency. The vacuum belt conveyor is continuous, allowing the electrode sheets to be transported from one end to the other continuously while completing the dust removal operation without interrupting the production process. This ensures that both sides of the electrode sheets are thoroughly cleaned, avoiding the problem of incomplete cleaning that may occur with single-sided dust removal.

[0020] 3. This fully automated ultrasonic dust removal equipment for positive and negative electrode sheets of new energy batteries, through the coordinated use of a fixed base, left and right positioning slides, and front and rear positioning slides, can achieve precise positioning of the electrode sheets. This not only improves the accuracy of the electrode sheets during processing but also ensures the smooth progress of subsequent unloading and stacking steps. The coordinated use of a loading robot, an unloading robot, a lifting loading component, and a lifting unloading component realizes automated loading, unloading, and stacking processes, greatly shortening the production cycle and improving production efficiency. It ensures that the electrode sheets are not damaged during processing and maintain their original cleanliness and quality, achieving efficient and precise processing and stacking of the electrode sheets. This not only improves production efficiency and product quality, ensuring high-quality production, but also reduces labor intensity and maintenance costs, bringing significant economic benefits to enterprises.
