To point out, Stacking at high speeds and with high precision
Therefore, operations synchronized with the servo motor drive enable high-speed stacking. In fact, the devices have a feature that allows them to correct electrode location (image processing, XY stage).
To clarify, High Throughput
Since the time it takes for stacking to halt is reduced thanks to an independent separator outer circumference winding operation.
As can be seen, proprietary technology reduces contact damage to electrode sheets.
Specifically, Increased maintainability
Consequently, the vertical structure of the major units allows for increased maintainability. Provided that, access to each unit is easier and maintenance time is decreased. When compared to traditional horizontal construction.
Explicitly, Tool change-out to accommodate different product types
While each unit has interchangeable attachments and parameter adjustments. Thus, to accommodate different battery sizes.
Another key point, APPLICATION
To emphasize, Li-Ion Batteries, Li-Ion capacitors, and electrical double-layer capacitors.

Another key point, Automatic Cell Assembly Systems
Therefore, TEXMAC’s HPS (Hitachi Power Solutions) line of automatic cell assembly equipment is suitable for a wide range of applications. For example, laminated, cylindrical, prismatic, and coin-shaped consumer batteries. As well as large automotive secondary batteries and automotive parts for electric vehicles (EVs) and hybrid vehicles (HVs).
To clarify, HPS’ experience and technology gathered over many years of commitment to automatic assembly. Therefore, HPS’s automatic assembly ensures the equipment’s stable operation. As a result, we contribute to increased productivity and high-quality assembly.
As a result, HPS offers a variety of systems. In effect, from a stand-alone unit to a complete manufacturing line. Obviously, according to your specific needs. All in all, to increase your production and efficiency. In a word, HPS can recommend assembly lines. in fact, which combines the cam and linkage mechanism and the servo cylinder mechanism with robot-based assembly.
Certainly, Contamination Free
- Such as optimized design minimizing particulate generated from the machines
- For instance, Cam & Link System for smooth motion
- For one thing, dust isolation mechanism for respective processes
As an illustration, Welding
- Such as, For Resistance Welding
- In particular, Laser Seam Welding
- Friction Stir Welding (FSW)
- Explicitly, Ultrasonic Welding
- Significantly, Laser Spot Welding
- Hot Welding
- Specifically, Crimping
On the positive side, Electrolyte Dispensing
- Therefore, the dispensing system developed by HPS operates under a high vacuum with a metering pump
- While the Injection head operates under high vacuum
- So that, experience-based proposals for the most suitable dispensing and impregnation processes achieve a faster cycle (Prior evaluation for the process using a dispensing testing machine)
