Robot gripper and clamp quick-changing mechanism

Abstract

The invention discloses a robot gripper and clamp quick-changing mechanism which comprises a quick-changing mechanism workbench, a robot finger fixing support, quick-changing fingers, a first sensor fixing device, a second sensor fixing device, a robot gripper and quick-changing base grippers. Front and rear positioning mechanisms are arranged on finger fixing blocks, and the robot fingers are replaced through cooperation of the front and rear positioning mechanisms and the quick-change base grippers, so that finger replacement failure caused by movement of the finger fixing blocks in the replacement process is prevented; a mechanism capable of automatically replacing the fingers is additionally arranged in an automatic line, so that the whole production line does not need to be stopped when the fingers are replaced, the production efficiency of the whole production line can be improved, and the time for manually operating a machine is shortened; and the whole operation process of the robot is executed through a prefabricated program sequence, and manual participation is reduced, so that the error probability is reduced, unnecessary safety risks are avoided, and efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a quick-change mechanism for robot grippers and clamps. Background technique [0002] With the continuous improvement of production efficiency, the demand for flexible manufacturing is gradually increasing, especially the flexible manufacturing of multi-variety and small-batch production has become the latest hot topic. It is very important to solve multi-variety, small-batch production processes and tooling fixtures There are two problems. The upgrading of products continues to accelerate. To realize automated production and manufacturing, the highly flexible interchange of robots and fixtures is very critical. How to realize the interchange of robots and fixtures with high efficiency and low cost is particularly important. Existing robot grippers There are the following disadvantages during use: [0003] In the multi-variety and small-batch automated production process, the rep...

AI Technical Summary

Problems solved by technology

[0003] In the multi-variety and small-batch automated production process, the replacement of robots and fixtures is time-consuming and laborious. Multiple equipments are operated online and one equipment is replaced with fixtures. All equipment is shut down and waits. The cost is high, the time is long, and the efficiency is low, which is very unfavorable for automated production (efficiency problem );

[0004] Automated production safety is a very important issue. In the process of product changeover, humans need to go to the production line to participate in the operation. The replacement of robots and grippers is the most involved project. Generally, the time is the longest, limited by space, and the safety risk of the operation process Big (security issue);

[0005] In order to maximize the efficiency and safety of the production line and minimize the downtime of the equipment, it is necessary to use efficient robots and quick-change jaws of the fixture. The current product prices on the market are high, the product design is complicated, and the cost of product failure or damage replacement is high, which is not conducive to large-scale production. Area usage, multi-variety, small-batch production mode is difficult to accept in terms of flexible production cost, which is not conducive to large-scale promotion and popularization (cost issue);

[0006] Common robots and fixtures need to be driven by external force to replace the claws. The product design and production process are complex, not energy-saving and environmentally friendly, and resources are somewhat wasted when the same mechanical performance is achieved (energy-saving and environmental protection issues)
