Description

Robot clamping mechanism convenient for adjusting clamping force Technical Field The utility model relates to the technical field of robot clamping mechanisms, in particular to a robot clamping mechanism convenient for adjusting clamping force. Background The robot clamping mechanism is an important part for grabbing, carrying and operating objects when the robot performs tasks, is widely applied to various fields such as industrial production, logistics, medical treatment, service and the like, and is required to adjust the clamping force of the clamping mechanism when clamping electronic products such as circuit boards, so that damage to the circuit boards in clamping is prevented. Through the search, chinese patent "a compound anchor clamps" grant bulletin number "CN218313601U" based on industrial robot is through splint cylinder, movable splint, flexible gasbag and communicating pipe, has realized inflating flexible gasbag, and then carries out flexible clamp to the product and get, avoids producing the damage to the product. In the above application, because the path that the flexible air bag stretches due to sufficient air cannot be controlled, the pressure distribution of the contact surface of the inflated flexible air bag to the product is uneven, and then the local overpressure clamping of the product is easy to cause, so that the clamping effect ‌ of the product is affected. Therefore, a robot gripping mechanism convenient for adjusting gripping force is proposed to solve the above problems. Disclosure of utility model The utility model aims to solve the problems and provide a robot clamping mechanism which is convenient for adjusting clamping force, thereby solving the problem of carrying out partial overpressure clamping on products.
