For industrial robots, material handling is one of the most important applications in the capture process. Industrial robots are powerful, multi-functional manipulators, and the success of their tasks directly depends on the traction mechanism. Therefore, the traction mechanism at the robot's end effector must be designed according to the actual operation of the task and the requirements of the working environment, resulting in a diverse range of traction mechanism structures. Most mechanical grasping mechanisms are two-jawed, and can be categorized as rotating or translational. Various grasping methods can be divided into internal and external gripping. Based on structural characteristics, they can be classified as antenna, electric, hydraulic, and cat-like mechanisms. The advantages of this model include easy pressure transmission via air, high speed, no medium-level working contamination, better fluidity than hydraulic systems, low pressure loss, and suitability for remote control. What are the types of industrial robot grippers, and what are their characteristics?
Types of industrial robot grippers
1. Rotary connection mechanism crane
The device's fingers are secured to bolt clamps for easy replacement, and the clamps can be significantly expanded.
2. Straight-bar dual-barrel translator
The fingers end with a mechanical device typically mounted on a straight rod, and the installation of the seat completes the process. As gas pressure enters the two vent rods, a gas cylinder gradually moves eastward until the work is finished.
3. Internal preparation for connecting the automatic lifting platform rod.
Force transfer is achieved through four fastening mechanisms. The directional support, unlike the external clamping type, is primarily used to catch thin-walled workpieces with internal holes. After cutting the mechanism supporting the workpiece, three fingers are typically installed to ensure stable positioning within the recess.
Features of industrial robot grippers
The mechanism by which inhalation ends body movement is achieved through suction created by negative pressure in the suction device. This model is primarily advantageous for capturing objects that are large, of moderate thickness, and of varying hardness, such as glass, paper, and steel. Methods for generating negative pressure can be categorized as follows:
1. Extrusion Absorbent Type
The air in the adsorption plate is depleted due to downward pressure, causing the adsorption plate to generate negative pressure in the form of adsorption of the body. This is beneficial for models used to capture small, thin, and lightweight workpieces.
2. Vacuum Adsorption Exhaust Pump
The suction pump vacuum is connected via an electromagnetic control valve. When air is drawn into the suction chamber, the suction tube pulls it away, creating negative pressure to absorb the body. Conversely, when the control valve connects the suction tube to the outer casing in the air, the suction tube loses its suction and reduces its effectiveness.
3. Typically closed cat mechanism
The drilling rig is maintained using powerful spring preload and hydraulic release. It remains in a state of readiness when the machine is unable to perform its task. The infrastructure is a combination of spring pressure that enhances tilting levels, cranes, and other mechanisms, allowing the tiles to act as axially moving seats, pushing the tiles radially.
