Filling
The pouch cell is received in a holding device for the process Then the electrolyte is directed into the cell and the cell is filled by means of a highly accurate dosing nozzle. Finally the pouch foil is sealed in a vacuum. Then it is inserted in a goods carrier and moves on to forming and ageing.
Monitoring suction pressure
Ensuring reliable gripping
The negative pressure on the suction nozzles makes it possible to fix the electrode sheet in place by inserting it into a folded separator. Monitoring and control of a constant suction pressure is necessary for precise positioning of the electrode sheet.
Enhancing performance
Solution
Series PN vacuum sensors reliably detect the required negative pressure. If the minimum values are not reached, the suction gripper remains in its initial position to prevent damage to the workpieces and systems. If the pressure sensors need to be replaced, the set parameters can be copied to the new sensor via IO-Link. This saves time and prevents possible setting faults.

Robot gripper navigation
Ensuring reliable gripper navigation
Navigation of the gripper is necessary to remove the cells from the goods carrier and to position them in the holding device. Automated gripper systems increase the productivity of many applications, as they carry out monotonous manufacturing steps more quickly and evenly than a human. Monotonous movements with heavy objects are bad for workers’ health and lead to frequent absences. If the robot takes over these activities, the availability of the system increases.

Enhancing performance
Solution
ifm's 3D sensor detects the object position and transmits it to the robot control, which controls the gripper. Automatic adjustment of the coordinate systems of the handling robot and the 3D sensor can save time and money during installation.

Collision avoidance
Preventing collisions while transporting goods
The purpose of collision protection of automated guided vehicles (AGVs) is to protect people and also to protect machines and the robot itself. Correctly avoiding obstacles prevents injuries to persons and reduces machine downtimes while increasing the overall efficiency of operation.

Enhancing performance
Solution
With the O3R robotics platform, ifm offers a multi-camera and sensor system for complex applications. It was developed to manage the degree of automation of the fifth level, complete automation without any interaction of a driver. The O3R robotics platform is specifically designed and dimensioned for application scenarios where several cameras and sensors are used simultaneously in a combined way. The system thus significantly reduces the individual development work for these usually complex applications.

Completeness check of goods carriers
Ensuring resupply for problem-free production
Coordination of automated work steps and intralogistics processes plays an important role in flexible production processes. To ensure prompt resupply of cells or empty goods carriers, the filling quantity of the goods carrier system must be queried. This leads to greater system availability and also saves time and money.
Ensuring system availability
Enhancing performance
Solution
ifm's 3D sensor has a wide variety of uses. A typical application is detecting underfilling. The 3D sensor compares the image with the programmed model and indicates deviation by means of a switching output. It can be integrated into automation systems via digital I/Os or Ethernet interface and ensures necessary communication.
