Perforation device for battery module
A recently filed patent (Publication Number: US20230311179A1) describes a perforation device and system for battery modules. The device includes a loading unit, a fixing unit, and a perforation unit. The loading unit conveys and loads the battery module in a longitudinal direction, while the fixing unit fixes the battery module in place. The perforation unit approaches the battery module and perforates it. The fixing unit contacts the battery module on the opposite side of the perforation unit and suppresses its movement.
The perforation unit can include a longitudinal perforation module that approaches the battery module in the longitudinal direction and perforates it, as well as a transverse perforation module that approaches the battery module in a transverse direction and perforates it. Similarly, the fixing unit can include a longitudinal fixing module that approaches and contacts the battery module in the longitudinal direction to suppress longitudinal movement, and a transverse fixing module that approaches and contacts the battery module in the transverse direction to suppress transverse movement.
In some embodiments, the longitudinal fixing module and transverse fixing module are arranged in pairs, with the battery module positioned between them. The longitudinal perforation module and transverse perforation module move towards the respective pairs of fixing modules to perforate the battery module.
The perforation device can also include a vertical perforation module that approaches the battery module from above and perforates it. The loading unit of the device includes guide frames and loading bars that help convey and align the battery module.
The patent also describes an identification unit that obtains an image of the battery module and a control unit that controls the fixing unit and perforation unit based on the image. A sensor unit can detect the position and attitude of the battery module, and the control unit can use the input signal from the sensor unit or the image to control the loading unit, fixing unit, and perforation unit.
The patent also includes a perforation system that includes a guide device and a perforation device. The guide device conveys and aligns the battery module, while the perforation device perforates the battery module. The guide device includes a guide frame, a first conveying unit, and an alignment unit. The perforation device includes a loading unit, a fixing unit, and a perforation unit. The alignment unit includes a first link and a second link that help align and move the battery module.
Overall, this patent describes a perforation device and system that can efficiently and accurately perforate battery modules, with various configurations and features to ensure proper fixation and movement suppression.
