Industrial robots need an accurate and simple end-effector that can handle many different parts, and it is necessary to know what type of parts will be handled before selecting the gripper of the industrial robot. Precautions for the selection of industrial robot claws
1) Shape
Asymmetrical, tubular, spherical and tapered parts are a headache for robot cell designers, it is very important to consider the shape of the part, some fixture manufacturers are able to pick different fingertips, can add to the fixture to get used to the specific application, and ask if the fixture can be suitable for your detailed application.
2) Size
The minimum and maximum dimensions of the object to be processed are very important data. You need to measure a few other orientations to see the best gripping orientation for the fixture. The need to consider a few shapes of the interior and exterior.
3) Number of parts
Whether it's using a thing changer or a self-habituation fixture, it's important to make sure that the robot can grasp all parts correctly. Tool changers are large and valuable, but they can work on the virtual part of a part with the right customization.
4) Portions
It is essential to know the maximum weight of the part. To understand the payload of the gripper and robot. Secondly, ensure that the gripper has the required clamping force to handle the part.
5) Materials
The information component of the component will also be an important part of the clamping plan. Dimensions and components can be handled by the fixture, and the data needs to be compatible with the fixture to ensure that the parts are gripped. For example, some grippers cannot be used to handle fragile items (e.g. ceramic, wax, thin metal or glass, etc.), simply damaging items. However, in the case of self-accustomed fixtures, gripping the surface can appropriately reduce the impact on the appearance of fragile parts, so force manipulation fixtures can also be part of the solution plan.
6) Production plan
Demand considers whether the production of a product will change over time, and if the assembly line has been making the same parts for the past decade, it probably won't change very often. On the other hand, if the assembly line is going to integrate new parts every year, it should be considered that the fixtures should be able to get used to these additions. It is even possible to consider whether the gripper used is accustomed to other applications. With this in mind, pick a gripper that will allow the gripper to get used to the potential future operation of the robot cell.
Once the part standard is confirmed, this data can be compared to the available fixture standard. After the shape and size of the parts that must be processed, it is possible to check the stroke of the jig that is required. Taking into account the information and weight of the part, the required clamping force is calculated. What are the different parts that the fixture is capable of, being able to see if the robot needs a tool change device, or maybe whether a single fixture is working properly.
Choosing the right gripper can make the industrial robot function well and get the most out of it.

The wire feeding method of the OTC welding robot
1. Push wire feeding method. This kind of wire feeding structure is relatively simple, light weight, and convenient operation and maintenance. However, the wire feeding hose is relatively long, the resistance is greater in the process of wire feeding, the wire feeding process is unstable, and the welding power is simply affected.

OTC robot contacts need to be replaced
Contacts are one of the items that often replace welding materials. During this time, the contact fixes the direction of the wire, and since the instantaneous current that moves when the arc is closed after welding is too simple to melt the contact outlet, it must have a role. The wire and contacts have been welded together, so that the welding can no longer be performed ...

OTC Odichi welding robot problem solving
1. The weld bead and welding trajectory cannot be corrected
First of all, in teach-in mode, the empty walk procedure ensures that the welding orientation is correct. Secondly, consider that there is a problem when soldering*** is searching. At this time, it is necessary to consider the way the welding robot finds the weld bead (arc or laser) to set it.

OTC Odichi welding machine to reduce spatter method
Splash issues
Because metal is thrown from the weld point to adjacent surfaces, spatter reduces power and adds expense to the installation line. After the welding is completed, the welder needs to sort out the weld, and the rest of the data is wasted.
Many welders think it's part of welding. Many people learn ...
