As a key part of the lithium battery production process, the electrolyte injection quantity directly affects the electrochemical performance and safety of the battery. With the scale production of cylindrical batteries and the development of thin and light digital batteries, the application of micro-dispensing pump ushers in a period of opportunity for development.
On the one hand, the segmented application scenarios such as electric vehicles, power tools and light vehicles boost the demand for 18650/21700 cylindrical batteries to usher in an explosive period, and the scale production of batteries requires improved efficiency and more liquid injection stations, which conventional liquid injection pumps can no longer meet the demand.
The smaller, more convenient electrical integration, lower cost and stable accuracy of the microfilling pump came into being and is accelerating the scale penetration in the field.
On the other hand, the development of digital products such as TWS headphones and other thin and light products, Bluetooth and button battery products are becoming smaller and smaller, and the control of liquid injection volume and liquid injection accuracy is becoming more and more demanding, so the introduction of micro-dispensing pump is also imminent.
As a high-tech enterprise focusing on fluid precision control systems and solutions, Guangzhou Ascend's products in the field of lithium have served most of the top 30 customers in lithium, and are widely used in listed companies and multinational companies in the electronics, contact lens, pharmaceutical, medical device, capacitor, biochip, and semiconductor industries, as well as expanding its business to the United States, Japan, Korea, Singapore, Malaysia, Russia, Sweden, Italy and other overseas regions.
Forward-looking targeting micro-dispensing pump applications, Guangzhou Ascend targeted to launch FSH-MIC series micro-dispensing pump, not only digital, cylindrical batteries and other lithium battery application scenario needs, its products are suitable for different mechanical engineering application scenarios including cleaning before welding of aluminum parts, photoresist coating machine, batch of liquid filling support.
Eight advantages of micro-dispensing pump
According to Ascend Guangzhou, the FSH-MIC series micro-dispensing pumps have the following eight advantages in mechanical.
1. Small size, easy to install and integrate.
2. Simple control, +24V voltage signal is sufficient.
3. High purity ceramic with high polishing treatment, no impurities will be precipitated during the process of adding liquid.
4. High precision (down to within 0.3%) and high consistency.
5. Adding volume from μL level to mL level.
6. Fast speed and high efficiency of liquid addition.
7. Acid and alkali resistance, corrosion resistance.
8. High return on investment, service life of 5-10 years or more, very few wearing parts, very low maintenance costs, simple operation and maintenance.
Application scenarios of micro-dispensing pump
1. The link of cleaning before welding of aluminum parts. When welding aluminum and aluminum alloy weldments, the oxide film and oil on the surface of the weld port should be strictly removed before welding, and the quality of removal directly affects the welding operation and the quality of the joint. Micro-dispensing pump does not precipitate any impurities when injecting the cleaning agent, and can operate trouble-free for 7*24 hours.
2. The link of photoresist applicator. FSH-MIC series micro-dispensing pump can spray in photoresist accurately (about 0.2-5ml) on the wafer to ensure consistency between wafers, with strong stability and accuracy.
3. The link of the batch of liquid filling supporting. Micro-dispensing pump supports multi-channel simultaneous work, suitable for high-precision, small dose of liquid dispensing. It can work with the production line and has the advantages of compact structure, easy operation and high reliability.
4. The link of Bluetooth battery, button battery battery liquid injection. The micro-dispensing pump can realize quantitative electrolyte liquid injection, which is resistant to acid and alkali corrosion and ensures the accuracy and stability of liquid injection.
5. The link of 18650/21700 cylindrical battery liquid injection. 18650/21700 and other batteries need smaller size, more convenient electrical integration, lower cost and stable precision micro-dispensing pump because of their fast production line efficiency and many liquid injection stations.
6. The quantitative addition of cleaning agents in the process of painting, bonding, welding and other metal parts surface residual contaminants will seriously reduce the adhesion of the coating, adhesive bonding layer, solidity. micro-dispensing pump discharge a stable amount of liquid to ensure the quality of parts cleaning, effectively avoiding adhesion decline and other problems.
7. The link of medical filling and spraying. Micro-dispensing pumps are widely used in biomedical dispensing, filling and refilling, and micro-spraying because of their high precision and resistance to acid and alkali corrosion.
8. Shielding oil, resulting in a series of problems in the metal coating process, micro-dispensing pump is very critical to the accurate delivery of shielding oil.
In addition to the above applications, Guangzhou Ascend FSH-MIC micro-dispensing pump is also widely used in electronics, contact lenses, pharmaceuticals, medical devices, capacitors, bio-chips, semiconductors and other industries.
