Problems solved by technology

However, when the parts are relatively small and two kinds of parts are mixed and placed in the same material frame at the same time, when the robot grabs different parts according to the vision system and places them in their respective designated stations, it is easy to cause interference between the robotic arm and the material frame wall , the robot gripper cannot distinguish between two different parts for error prevention, resulting in damage or failure of the placement station

Embodiment Construction

[0011] Such as figure 1 The robot grabbing device shown includes a flange 1 and a connecting rod 2, the flange 1 is used to connect with the robot arm, a cylinder base 3 is fixed at one end of the connecting rod 2, and a cylinder 4 is fixed on the cylinder base 3. A pair of slide blocks 5 are also slidably arranged on the cylinder block 3, such as Figure 2 to Figure 4 The shown cylinder 4 is slidably connected with the two sliders 5 through a pair of V-shaped chutes, and when the cylinder 4 expands and contracts, the two sliders 5 are driven to separate or move closer together under the action of the chutes. Also be respectively provided with connecting plate 6 on two slide blocks 5, be provided with grasping finger 7 respectively on two connecting plates 6, drive connecting plate 6 to move when slide block 5 moves, thereby make two grab fingers 7 Separate or move closer to complete the action of grabbing parts. These two grasping fingers 7 are all parallel to the connectin...

Abstract

The invention discloses a robot grabbing device which comprises a flange and a connecting rod. An air cylinder base is fixed onto the connecting rod; an air cylinder is fixed onto the air cylinder base; a pair of sliding blocks are arranged on the air cylinder base in a sliding mode; the telescopic end of the air cylinder is connected with the two sliding blocks in a sliding mode through a pair ofsliding grooves distributed in a V shape; the air cylinder can control the two sliding blocks to be separated or close through stretching and retracting; each sliding block is provided with a connecting plate; each connecting plate is provided with a grabbing finger deviating from the center of the corresponding connecting rod; the air cylinder base is provided with a pair of electromagnetic induction switches for detecting the stretching and retracting distance of the air cylinder; a proximity switch for detecting the moving distance of one sliding block is further arranged on the air cylinder base; and a detection block matched with the proximity switch for detection is arranged on the sliding block detected by the proximity switch.

Description

technical field [0001] The invention relates to the field of robot automation, in particular to a mechanical grabbing device. Background technique [0002] At present, in the field of industrial automation, industrial robots are widely used. The use of industrial robots is of great significance to ensure personal safety, improve the working environment, reduce labor intensity and reduce costs. The realization of robot movements is jointly completed by the robot body and the end effector. The end effector is also called the hand of the robot. It is a component installed on the wrist of an industrial robot to directly grasp the workpiece or perform operations. Due to the various applications of robots, end effectors are usually specially designed for a specific occasion. [0003] The end effectors of robots in the industrial field generally use cylinders or servo motors to drive mechanical clamping mechanisms to complete the grasping of parts. However, when the parts are rel...
