1. Pick up and place

A pick-and-place mission refers to picking up a piece and placing it on another site. For workers, this is one of the most repetitive tasks today. Boring and vulgar operations can easily lead to worker errors, and highly repetitive body movements can also easily lead to physical fatigue and injury. However, through the use of cobots, it is possible to completely liberate human labor.

In practice, workers are able to use machines to pick up items from pallets or conveyor belts for packaging or sorting. However, picking up items from conveyor belts also requires advanced vision systems. In addition, pick-and-place cobots also require an end-effector to grip objects, which can be a gripper or vacuum suction cup device.

2. Take care of the equipment

Equipment care requires workers to stand in front of CNC machines, injection molding machines, or other similar equipment for a long time to pay attention to the operational needs of the machine, such as replacing tools or replenishing materials. This process is time-consuming and vulgar for the operator.

In this case, the use of cobots not only frees up workers, but also improves productivity by allowing one cobot to maintain multiple machines. Caring cobots, on the other hand, require device-specific I/O docking hardware. These hardware indicate when the robot will enter the next cycle of production or when it needs to replenish the material.

3. Packaging and palletizing

The packaging and palletizing of products falls under a subcategory of the Pick & Place category. Before the product leaves the factory floor, it needs to be properly prepared for transportation, including shrink wrapping, box assembly and loading, box sorting, and pallet placement for shipment. This type of work has a high repetition rate and contains some small loads, making it ideal for replacing manual work with cobots.

Rapid product changeovers are key to the business of high- and low-volume mass production companies. This use requires the use of conveyor tracking to synchronize the movement of the robot and the conveyor. For products with inconsistent shapes, it is also necessary to combine the vision system when using them.

4. Finishing operations

Manual finishing is done by hand, and the process is often strenuous. The sensation caused by something may also cause injury to the operator.

Cobots provide the force, repeatability, and precision needed for finishing. The types of finishing that can be done include polishing, grinding, and deburring.

In addition, humans can teach robots to perform corresponding actions through manual teaching or computer programming. As a result, the robot can be finished with different sizes of parts through an end-effector or a built-in force sensing device.
