How to choose the robot claw correctly? The selection of robot claws is always an important part of robot arm design. We have given you the following tips, basic knowledge of grip selection for specific parts.
The selection of fixture is very important for the success or failure of robot unit integration. You need a terminal actuator that can handle as many different parts as possible, and be precise and simple.
First you have to figure out what type of parts this grab will handle. The following lists the key points that we consider systematically when we choose robot claws. Choosing the right grip works well and has good functionality and maximum effect, but if it doesn't fit your application, its advantages will diminish.
size
The minimum and maximum size of the object to be processed is very important data. You need to measure other geometric positions to see the best grip position of the fixture. Internal and external geometry needs to be considered.
weight
The maximum weight of the part must be known. First, we need to understand the payload of the grab and robot. Second, make sure the grip has the required grip to handle the parts.
Material Science
The material composition of the component will also be a very important aspect of the clamping scheme. Dimensions and weights can be handled by clamps and materials need to be compatible with clamps to ensure that the components are held tight. For example, some grab hands cannot be used to handle fragile items (such as ceramics, waxes, thin metals or glass, etc.) and can easily damage the items. But for our adaptive fixture, the grab surface can reduce the impact on the fragile part surface, so the force control fixture can also be part of the solution.
shape
Asymmetrical, tubular, spherical and tapered parts are headache for robot unit designers. It is important to consider the shape of the part. Some fixture manufacturers can choose different fingertips and can be added to the fixture to suit specific applications. Ask if the fixture can be used for your specific application.
Number of parts
Whether using tool changer or adaptive fixture, it is necessary to ensure that the robot tool can correctly grasp all parts. The tool changer is large and expensive, but can work on the virtual part of the part using the right customization tools.
Your production plan
In addition, you should consider whether your production will change over time, and if the assembly line has been making the same parts over the past decade, it may not change frequently. On the other hand, if the assembly line is to integrate new parts every year, it should be considered that the fixture should be able to accommodate these additions. You can even consider using your grip to adapt to other applications. Consider this factor and choose a grab. Ensure that the fixture can adapt to the potential operation of the robot unit in the future.
By determining the part specifications, you can now compare this data to the available fixture specifications. By the shape and size of the parts that must be processed, you can determine the travel of the fixture you need. The required clamping force can be calculated considering the material and weight of the part. What are the different parts that the fixture can handle, can see whether the robot unit needs to change the tool device or whether the single fixture can work normally.
