Traditional adhesive supply equipment suffers from problems such as insufficient degassing, affecting adhesive quality; limited mixing and dispensing methods, making it difficult to adapt to adhesives of different viscosities; lack of precise monitoring functions for pressure, level, and temperature, making it difficult to detect abnormalities in adhesive supply in a timely manner; and poor equipment maintenance and operation convenience. These issues fail to meet the demands of efficient and high-quality lithium battery production, thus necessitating an improved adhesive supply system to address these problems. Utility Model Content

[0003] The main purpose of this invention is to propose a glue supply system for lithium battery production, which aims to solve the technical problems of insufficient degassing, single mixing and glue dispensing methods, lack of precise monitoring, and inconvenient operation and maintenance of traditional glue supply equipment.

In this embodiment, the feeding assembly includes a feeding pipe 11 and a first switching valve 111. The feeding pipe 11 is connected to both the pressure tank 1 and the feeding device. The first switching valve 111 is mounted on the feeding pipe 11 and is used to control the opening and closing of the feeding pipe 11.

In use, the motor 2 drives the spiral mixing structure to rotate and mix the adhesive, while the speed controller adjusts the output power of the motor 2, thereby regulating the mixing speed of the spiral mixing structure. In this embodiment, the spiral mixing structure can be a specific component such as a mixing paddle or a mixing element, and the adjustable range of the motor 2's output power is between 20W and 450W. During operation, the output power of the motor 2 can be determined batch-wise based on factors such as the viscosity and type of the adhesive, the type and location of the dispensing product, etc. That is, before production, the output power of the motor 2 is adjusted to a specific value, and then maintained at that power during production until the aforementioned factors change. Then, a new output power is determined based on the changed factors. Alternatively, the output power of the motor 2 can be changed at any time based on the monitoring results of the monitoring sensors or the instructions of the operator to adapt to changing production needs.

[0025] Furthermore, the vacuum degassing assembly includes a vacuum pump 4, a vacuum tube 41, and a third switching valve 411. The output end of the vacuum pump 4 is connected to the pressure tank 1 through the vacuum tube 41. The third switching valve 411 is installed at the end of the vacuum tube 41 and is used to control the connection between the vacuum pump 4 and the pressure tank 1. When the adhesive is stirred by the spiral stirring structure, the vacuum pump 4 can be activated to create a vacuum environment in the pressure tank 1 to remove air bubbles from the adhesive. In addition, the vacuum pump 4 can also assist in material extraction during feeding.

[0026] Compared to existing technologies, the vacuum degassing component added to this invention can create a vacuum environment within the pressure tank 1, thereby achieving more efficient and thorough glue degassing. During feeding, a vacuum pump 4 can also assist in material extraction. This design helps improve the quality and efficiency of glue processing. Furthermore, compared to existing technologies with a single stirring method, this invention adjusts the speed of the spiral stirring structure by setting a speed controller to regulate the output power of the motor 2. This allows for adjustment and determination of the motor 2's output power based on factors such as the viscosity and type of glue, the type and location of the dispensing product, and the monitoring results of sensors or operator instructions.

The dispensing controller 5 is used to control the opening and closing of the dispensing valve 125 and the dispensing output. Specifically, a filter 123 and a cleaning drain port 122 are also provided in the middle of the dispensing pipe 12. The filter 123 is used to filter the glue, and the cleaning drain port 122 is used to clean the dispensing pipe 12 and the filter 123, and to discharge the impurities accumulated in the filter 123.

[0029] Preferably, the glue dispensing assembly further includes an air inlet pipe 13 and a precision pressure regulating valve 131. The air inlet pipe 13 is connected to the pressure tank 1 and a compressed air source, respectively.

After the glue in the pressure tank 1 has been processed, compressed air is input into the pressure tank 1 through the air inlet pipe 13, thereby forcing the glue to be discharged from the glue dispensing pipe 12 at the bottom of the pressure tank 1.

[0030] Preferably, the adhesive supply system for lithium battery production further includes a monitoring component, which includes monitoring sensors, a programmable logic controller (PLC), and a touchscreen.

Based on the monitored data signals, the analysis results, the instructions input from the touchscreen, and the preset logic program, it precisely controls the start, stop, and power adjustment of various valves and power components (such as the vacuum pump 4 and the stirring motor 2), thereby ensuring that the entire process of adhesive from feeding, processing to output is automated, stable, and reliable. This design improves equipment maintenance and operational convenience, meeting the high-efficiency and high-quality requirements of lithium battery production.

[0032] Specifically, the working principle and process of this utility model are as follows: Before and during lithium battery production, monitoring sensors can precisely monitor specific data such as pipeline pressure, adhesive level, compressed air humidity, and adhesive temperature. Based on this data and the requirements of adhesive and product production, operators and programmable logic controllers can control the start, stop, and power adjustment of various valves and power components, ensuring an automated, stable, and reliable process for the entire adhesive supply chain, from feeding and processing to output.
