Factors Enabling High-Precision Force Control
High-precision contact force detection
Unable to detect minute impacts upon workpiece contact due to sliding resistance and ambient vibration detection.
The unique algorithm automatically resets the reference value to zero based on the average value of sliding resistance and ambient vibration, and it detects the impact of workpiece contact.
Immediate cessation upon contact
Example Problems and Solutions
Problem
We are using adhesives when assembling elements and want to manage the force!
The PPR advantage
It's great to have an all-in-one package with a force sensor integrated.
Since angle adjustment is also required, it is aligned from the position taken by the camera.
Problem
The cover of a module product has become thinner, and we want to manage damage by not pushing it down too much!
The PPR advantage
The PPR is all-in-one, so it can be easily attached. Since there are numerous processes to pick and place small components, we want to adopt them as standard.
The force sensor confirms the impact force and can be used for traceability.
Problem
Workpieces develop cracks with more than a certain amount of load. We want to both reduce cycle time and manage damage!
The PPR advantage
Using the contact stop function, the PPR was able to detect a load of 15 gf and stop. It was able to achieve under 0.2 seconds at a 5 mm stroke, satisfying our requirements.
Installation Support
Support staff who have mastered the use of the PPR will verify many aspects of the implementation to ensure that there are no issues.
We will confirm the details of what product and type of operation you want during the consultation process, so please feel free to contact us.
Technical calculations
(cycle time and load capacity)
We can pre-calculate the feasibility of operations based on the mass and inertia of the conveyed object and the movement pattern.
Testing
(workpiece pick and place trials)
We will perform testing using actual workpieces, nozzles, and other parts to determine whether or not the desired operation can be performed.
Demo machine rental
We would be happy to lend you a demo unit during the consultation process. Please contact us with details of what you're looking for.
Sample programs
We can provide a sample operation program that matches the actual usage concept. You can also contact us about PLC connectivity.
