Description

Technical Field

[0001] The utility model relates to the technical field of automation, in particular to a multifunctional grasping mechanism used at the end of a robot. Background Art

[0002] An automated grasping mechanism is a device used to clamp and manipulate objects in an automated system. It is usually composed of a mechanical claw, actuator, sensor, and control system. It is widely used in industrial robots, automated production lines, warehousing and logistics systems, and other fields to grasp, carry, assemble, and process various objects.

[0003] At present, the suction of the mobile phone middle frame and the clamping of the blister tray to complete the automatic material picking and assembly or discharge mainly rely on the suction cups and air claws in the components to complete the automatic action through pneumatics. However, the inner cavity of the mobile phone product will have many hollows, and there are many types of products, and the positions of the hollows are different. This leads to the need for the existing mechanism to debug the position of the suction cup every time a different product is made. The debugging is very troublesome, and even if there are no hollow positions, there are many small through holes. When the suction cup absorbs the product at this position, the vacuum will be broken (the specified negative pressure cannot be reached) and the product cannot be sucked. Therefore, the position of the suction nozzle needs to be debugged for different products, and it is not easy to find the right position during debugging, which leads to unstable suction and grasping, which will affect the stability of the equipment and make its failure rate high, thereby reducing the overall production capacity of the equipment. In addition, in the production of mobile phone middle frames, a central locking rod is also needed to assemble multiple mobile phone products together for processing. At present, the traditional grasping mechanism requires manual semi-finished products, and then manually insert the locking rod to complete the assembly, which requires a lot of manual input and increases labor costs. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a multifunctional grasping mechanism for the end of a robot, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a multifunctional grasping mechanism for the end of a robot, comprising a mounting plate, wherein two lifting drive cylinders are arranged on the top of the mounting plate through an L-shaped mounting block, and the driving ends of the two lifting drive cylinders are provided with claw driving members, wherein the driving member of one of the claw driving members is provided with a claw, and the driving member of the other claw driving member is provided with an L-shaped clamping plate, and a T-shaped plate is arranged on one side, and a clamping plate is arranged at the bottom of the T-shaped plate, a nozzle mounting plate is arranged below the mounting plate through a mounting column, and four non-contact nozzles are arranged on the nozzle mounting plate.

[0006] Optionally, the clamping surface of the clamping jaw is provided with an anti-slip groove for improving the clamping effect.
