The lithium battery automatic intelligent coating machine is an important equipment in the battery production line. By wrapping the battery aluminum shell with a layer of PE blue film, the battery can realize the functions of weather resistance, corrosion resistance, friction resistance, vibration resistance, oil and water resistance, and reducing the risk of short circuit between the battery core and other components.
The equipment provides the finished battery code scanning for the previous process, then carries out coating, edge cutting, top and bottom glue folding, top cover insulation sheet pasting, size measurement, blanking code scanning, battery insulation test, battery weighing, and finally automatically blanking to the conveyor belt for the next process.
At present, with the development of new energy batteries, the coating machine equipment has risen, and it has become a blue ocean equipment that many automation companies are vying for and increasing investment.

As one of the key equipment for manufacturing lithium batteries, lithium battery automatic coating machine plays an important role in battery quality and manufacturing efficiency. Compared with the current domestic coating machine and foreign coating machine, there are still some pain points to be broken.
1 The coating yield is not high
The battery coating will appear bubbles, wrinkles, scratches, wire drawing damage, unevenness and other phenomena, which directly affect the insulation and thermal conductivity of the lithium battery.
2 Low envelope efficiency
The low positioning accuracy and slow response speed of the processes such as roll roll discharging and folding not only affect the efficiency of the whole machine, but also lead to low utilization rate of blue film.
This means that the battery coating machine that can achieve high quality and high efficiency will be more able to meet the market demand of downstream battery enterprises, so as to gain competitive advantage.
where there are challenges, there are opportunities. Aotong Research Institute specially aims at the demand of high speed and high precision in the core station of the cell coating machine. Through continuous technology docking and research and development innovation, it provides high-performance ATS series servo scheme to help the coating machine complete cell coating with high precision and high quality.
Feeding: The servo motor drives the gripper of the manipulator to realize the function of accurately grabbing the battery and putting it into the coating station.
Feeding: Servo control can set parameters according to the requirements of packaging film, accurate feeding.
Die: aluminum shell battery into the coating station, through the servo scheme, optimize the position setting time, can improve the response speed of the die.
Hanging: The servo motor is used to control the folding position, realizing the symmetry of the side edge up and down, and the high-efficiency folding of the top edge. After folding, squeeze the blue film forward by servo to prevent the corners of the blue film from warping.
☑ Improve production efficiency
Accurate positioning of loading and unloading, folding and other links (side folding positioning accuracy ≤ ± 1.0mm), efficient response, greatly improving the production efficiency of the whole machine.
With the assistance of the servo scheme, it supports parameter setting, status monitoring, built-in alarm and other functions to reduce debugging and downtime.
☑ Reduce production costs
Mechanical jaws replace manual feeding, reducing labor costs.
Servo precise positioning, can accurately control the amount of blue film, reducing material waste.
☑ Improving the quality of the envelope
The yield rate is as high as 99% (except for bad products caused by incoming pollution, etc.), and it is not easy to produce edge warping, bubbles, indentation and flanging.
