The invention is named as a manipulator grasping device, which mainly includes a left gripper assembly and a right gripper assembly on the gantry. The gantry is provided with a first control mechanism for controlling the rotation of the left gripper assembly and the right gripper assembly, and the gantry is provided with a second control mechanism for controlling the relative approach or distance between the left gripper assembly and the right gripper assembly. The gantry is provided with a linear guide rail, and the left gripper assembly and the right gripper assembly are both provided with a linear guide rail matching the linear guide rail. The slider is slidingly arranged on the linear guide rail.

The slider is installed on the side of the left gripper assembly and the right gripper assembly close to the door frame, and the linear guide rail is installed on the side of the door frame. The slider and the linear guide rail are installed along one side of the door frame to the other side. In this installation method, when the fork tines of the left gripper assembly and the right gripper assembly extend outward and fork the goods, for some heavy-loaded goods, the left gripper assembly and the right gripper assembly tilt inward, which causes serious wear on one side of the slider and the linear guide rail in the long term, shortens the maintenance cycle of the door frame, increases maintenance costs, is not suitable for heavy-load environments, and also reduces the applicability of the door frame. Utility Model Content
[0003] The technical problem to be solved by the present invention is: in order to solve the problem that the existing left gripper assembly and the right gripper assembly are cooperated with the slider and the linear guide to achieve sliding on the door frame, the slider is installed on the side of the left gripper assembly and the right gripper assembly close to the door frame, the linear guide is installed on one side of the door frame, and the slider and the linear guide are installed along one side of the door frame toward the other side. However, such an installation method causes the left gripper assembly and the right gripper assembly to tilt inward for some heavy-loaded goods when the fork tines of the left gripper assembly and the right gripper assembly extend outward and fork the goods, which causes serious wear on one side of the slider and the linear guide in the long term, shortening the maintenance cycle of the door frame, increasing the maintenance cost, being not suitable for heavy-load environments, and reducing the applicability of the door frame.

The load-bearing rollers are located between the corresponding anti-deflection plate and the left gripper assembly or the right gripper assembly. By rotatably arranging the load-bearing rollers on the portal body, the anti-deflection plates contact the load-bearing rollers when they move, thereby preventing the left gripper assembly or the right gripper assembly from deflecting from the portal body and increasing the load-bearing weight of the left gripper assembly and the right gripper assembly.
[0006] In some preferred embodiments, two sets of sliders and linear guide rails are provided between the left gripper assembly and the right gripper assembly and the portal body along the height direction of the portal body.
[0007] Because the left and right gripper assemblies are positioned one above the other on the mast body and are subject to their own weight, in order to better ensure stable and reliable sliding of the left and right gripper assemblies, in some preferred embodiments, the load-bearing anti-deflection mechanism is located between the two sets of sliders and the linear guide rails. By positioning the sliders of the left and right gripper assemblies at the top and the linear guide rails at the bottom providing support, stable and reliable operation of the left and right gripper assemblies is ensured.
[0008] In some preferred embodiments, a guide groove matching the anti-deflection plate is provided on the rear end surface of the door frame body, and one end of the anti-deflection plate is arranged in the guide groove.
[0009] The beneficial effects of the utility model are as follows: when the manipulator gantry of the logistics robot is in use, the slider and the linear guide are arranged along the height direction of the gantry body, and the cooperation of the load-bearing anti-bias mechanism effectively prevents the left gripper assembly and the right gripper assembly from being overloaded when forking goods, avoids serious wear on one side of the slider and the linear guide rail, ensures stable and reliable sliding between the slider and the linear guide rail, prolongs the maintenance of the slider and the linear guide rail, reduces maintenance costs, and also increases the load capacity of the manipulator gantry body for forking goods for the logistics robot, is suitable for the load weight of more goods, improves the applicability of the manipulator gantry for the logistics robot, and avoids the existing The left gripper assembly and the right gripper assembly are achieved by sliding on the gantry body through the cooperation of sliders and linear guides. The sliders are installed on the side of the left gripper assembly and the right gripper assembly close to the gantry, and the linear guides are installed on one side of the gantry body. The sliders and the linear guides are installed along the direction from one side of the gantry to the other side. In this installation method, when the fork tines of the left gripper assembly and the right gripper assembly extend outward and fork the goods, for some heavy-loaded goods, the left gripper assembly and the right gripper assembly will tilt inward, which will cause serious wear on one side of the slider and the linear guide in the long term, shortening the maintenance cycle of the gantry and increasing the maintenance cost. It is not suitable for heavy-load environments and also reduces the applicability of the gantry. BRIEF DESCRIPTION OF THE DRAWINGS
