FlexiBowl® Installation Guidelines
Support Base and Robot Placement
- The support base on which FlexiBowl® is installed should be as rigid as possible, in order to minimize the transmission of vibrations to the camera.
- The robot should be able to pick the parts on the entire vision area of FlexiBowl®, at any necessary angle. It is fundamental to ensure there is no collision between the robot arm and FlexiBowl®.
- The camera should be installed rigidly, centred and vertical above FlexiBowl® picking area, in order to make the entire surface visible. Regulations in all directions and a strong fixing are advised. Check the handbook and the drawings in the download area of our website for details.
Choosing the Correct Vision System
- In order to choose the correct vision system, keep in consideration that:
-The camera must determine the position of the parts accurately and detect all its essential details;
-The vision system must be able to manage all the necessary cameras;
-It must have a compatible elaboration time in comparison to the required feed rate;
-It must be able to keep a database of all of the receipts of the models to feed.
Robot Movement and Lighting Conditions
- After picking the part, the robot must move from the camera vision area as rapidly as possible, to allow a quick shooting of a new photo. The robot must not block out the camera vision area during the placing of the parts, or any other operation.
- Minimize any disturb produced by environmental light. Prevent any potential rays of light, even when using IR filters.
Lighting and Picking Area
- To ensure a homogeneous illumination in toplight applications, the dimension of the light must be adequately measured in comparison to the picking area.
- In some applications, due to the FlexiBowl® movements, some parts can accidentally fall out from the picking area. According to the type of parts and the requirements of the application, it might be necessary to install dedicated protections. These protections must not obstruct the picking area for the robot.
Handling Parts and System Accuracy
- If you are using a gripper, its fingers must be as slim as possible, so that the littlest space will be reserved as a free zone for picking. It is always advisable to use, where possible, non-bulky picking systems (i.e. suction gripper or inside/above picking systems).
- In those systems where an elevated accuracy (some tenths of mm) is required, we advise the use of “re-centring grippers” or “re-centring intermediary positioning” in order to guarantee the most accurate final placing.
Payload and Performance Considerations
- It is unadvised to exceed the maximum payload value or the parts' total weight.
- The FlexiBowl® system is based on a random principle; therefore, the parts’ availability is not always constant in time. When talking about performances, what we mean by “average feeding rate” is the average “pick and place time” in a few minutes period, without taking into consideration any possible waiting time due to other parts of the implant. We can make tests to determine the feed rate of each part and to verify if/how often a delay can happen.
Feeding Multiple Different Parts and other applications
- The simultaneous feeding of multiple different parts in the same feeder is possible only in rare cases.
We advise you to consult ARS for this kind of application.
- If different parts from the ones that must be fed are present in the vision area, the camera will not recognise them and the robot will not pick them. This will not create any problems to the system itself, but the final feed rate performance may be affected, up to the possible saturation point.
- The robot could remove any “wrong” parts only in rare cases. We advise you to consult ARS for this kind of application.
