Adhesive test whether the tape is in place, the unglued cell shall be discharged
Battery blanking 1 reliable grasp, no material dropping or entrapped materials, the repeated precision of the mechanism operation ≤±0.05mm
2. Flexible design of the manipulator, the parts such as the manipulator in contact with the product cannot be made of metal
1.3.1Mylar film and substrate feeding
1.1 device functions and introduction
This device is mainly used to realize the assembly (hot fusion) of battery bottom holder sheet and Mylar film, the cell envelope (hot fusion), adhesive and other functions (the following figure is a schematic diagram, subject to the actual design), the specific process is shown in the figure below (for reference only).
The feeding of Mylar film and bottom plate is mainly composed of Mylar film and bottom plate feeding platform, ion fan, bottom plate and mylyn feeding hand, translation module, etc. Because of the friction between Mylar film and film and between the substrate and substrate static electricity will lead to film and film absorption, through the blowing ion wind to remove the static electricity between them, when taking materials through the middle and at both ends of the friction film will be separated, to prevent a time to take more than one, multi-layer.
1.3.2 envelope hot melt location
① Adhesive mechanism is mainly composed of film placement mechanism, adhesive pulling mechanism, adhesive cutting mechanism and adhesive feeding mechanism. The main realization of the enveloped battery tail adhesive, in the adhesive before the battery is fixed, the adhesive feeding mechanism will tape to the battery tail; The rubber feeding mechanism has a vacuum alarm device, which will give an alarm when the rubber is missing or the rubber belt is not sucked up, and remind the staff to replace the rubber belt or cut the rubber again in time.
