In the electric gripper or servo gripper, the motor controls the jaw movement through the electrical input of the robot controller. These robot arm end tools are increasingly appearing in the industrial market. The following are five advantages of using electric grippers compared with other types of robot grippers.
1. Control the position of gripper fingers
By using the coding motor and appropriate control scheme, the position of the jaw can be determined by using the electric clamp. On the contrary, for traditional grippers, it is usually necessary to maintain the full range. When using the electric gripper, you can flexibly use only the minimum necessary clearance to approach the part, and then use the minimum travel to pick it up. Partial opening and closing help to select a wider range of part sizes without affecting the production cycle.
2. Test grip strength
Using the encoder, you can determine whether the gripper has picked up the part. Some electric grippers will transmit this information back to the robot controller. In many applications, in order to prevent errors, the handle must be detected. Doing this at the gripper level avoids putting other sensors into the loop, simplifies integration and reduces overall costs.
3. Control grip and speed
Since the motor current is proportional to the applied torque, the grip paper force applied by the paper tooth can be controlled. The same is true for closing speed. This can be helpful when dealing with fragile parts, for example.
4. No gas pipe: save electricity and maintenance costs
Many companies are shifting from pneumatic to electric to reduce operating costs. An important aspect of this transformation is to reduce the cost of pneumatic hardware and energy costs.
5. Cleaner grip
Some applications require a clean environment, otherwise air leakage may cause pollution. In this case, the electric gripper is the only feasible solution for picking up parts.
What are the advantages and disadvantages of multi-joint robot?
Joint robot is also known as joint manipulator or multi-joint robot. The motion of each joint is rotation, similar to human arm. Joint robot is one of the most common forms of industrial robots in the industrial field today, and it is suitable for mechanical automation in many industrial fields. Multi-joint robots are classified according to the structure of joint robots, for example, five-axis and six-axis joint robots, pallet joint robots, and planar joint robots SCARA, which have different classifications according to the structure; It can also be classified according to the work nature of joint robots, which can be divided into many types, such as: handling robots, spot welding robots, arc welding robots, painting robots, laser cutting robots, etc.
Advantages of multi-joint robot:
1. It has a high degree of freedom, 5~6 axes, and is suitable for almost any track or angle of work;
2. It can program freely and complete fully automated work;
3. Improve production efficiency and controllable error rate;
4. Replace many complex work that is not suitable for human completion and harmful to health, such as spot welding of automobile shell.
