Detailed Description

Preferred embodiments of the present utility model will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the mechanical gripper with the automatic trimming function provided by the utility model comprises an end pick-up 1 and a plurality of scissor connecting rods 2 movably connected to the end pick-up 1 through a first angle connecting piece 3, wherein each scissor connecting rod 2 is provided with an adjustable scissor 4 through a universal rotating mechanism 5.

The above-described components are described in detail below.

The end effector 1 comprises a main frame 11 formed by splicing a plurality of frame connecting rods, wherein the left side and the right side of the main frame 11 are connected with a plurality of clamping mechanisms 12 and a plurality of sucking mechanisms 13, and the clamping mechanisms and the main frame 11 form a mechanical gripper configuration together. A quick change tray 14 is also provided on the side of the main frame 11 remote from the product for ease of replacement. It should be noted that, to better fix the product, the clamping mechanisms 12 are symmetrically distributed on the left and right sides of the main frame 11, and the suction mechanisms 13 are also symmetrically distributed on the left and right sides of the main frame 11.

The clamping mechanism 12 comprises a pneumatic clamp 121 and a double-stroke cylinder group 122 for providing power for the pneumatic clamp 121, the suction mechanism 13 comprises a suction cup 131 and a single-stroke cylinder 132 for providing power for the suction cup 131, the positions of the pneumatic clamp 121 and the suction cup 131 relative to a product can be respectively adjusted through the double-stroke cylinder group 122 and the single-stroke cylinder 132, and an adjustable gripper is formed by matching with the main frame 11 to fix the product better.

In this embodiment, the plurality of scissor connecting rods 2 are disposed on the left and right sides of the main frame 11 in pairs, and in fig. 1, the number of scissor connecting rods 2 is two. It should be understood that the number of the scissor connecting rods 2 can be other, and the requirements of the use scene can be met. The shearing tool connecting rod 2 is hinged on one frame connecting rod of the main frame 11 through the first angle connecting piece 3 so as to realize rotation adjustment around the frame connecting rod and meet the requirements of shearing angles.

As shown in fig. 2, the adjustable scissors 4 include a pneumatic scissors 41 and a reciprocating cylinder (not shown) connected to the pneumatic scissors 41, and the pneumatic scissors 41 can be driven to reciprocate up and down by the reciprocating cylinder.
