New Cured-in-place Liquid Sealant Solution for Battery Cell Module Controllers
During the production of battery sensors, highly viscous liquid sealants are used to protect these sensitive electronic components from external influences and temperature-related stress and physical shock and vibrations.
With the goal of developing a flawless process solution for dispensing and curing liquid gaskets for cell module controllers, the system manufacturer and dispensing expert bdtronic and the UV expert Hönle have teamed up for a manufacturing process using the CPIG method.
Battery sensors play a crucial role in controlling and managing the performance and safety of electric vehicle batteries. They monitor parameters such as temperature, voltage, and current and report this information to the battery management system (BMS), which controls and monitors the battery’s charging and discharging processes.
During the production of such battery sensors, highly viscous liquid sealants are used to protect these sensitive electronic components from external influences such as dust, road salt, and moisture, as well as temperature-related stress and physical shock and vibrations.
These liquid sealants are typically identified as cured-in-place gaskets (CIPG). A machine manufacturer for technologies that include dispensing, bdtronic supplies automated dispensing systems for CIPG applications. These systems can also incorporate modules for plasma pretreatment/surface treatment, UV curing, and camera inspection.
A recent collaboration between bdtronic and Hönle created an inline, five-step process for CIPG dispensing and curing. In the first step, the component contours are pretreated with atmospheric pressure plasma to achieve better adhesion of the sealant. In the second and third steps, the highly viscous CIPG is applied in contours. In the fourth step, curing is carried out using a Hönle UV curing system. Step five involves the optical inspection of the finished part to ensure the highest level of quality and consistency.
