Note: the telescopic end of the cylinder extends outwards to drive the right upper end connected with the cylinder to move outwards, the left lower end is opened to enable the lower end of the X-shaped holder to be opened to hold the scissors or release the scissors after polishing is completed, and the left upper end and the right lower end are fixed all the time. On the contrary, when the telescopic end of the cylinder is retracted inwards, the scissors are clamped.

The fixing piece is separable from the scissors fixing seat.

Note: the purpose is that the fixing piece can be changed according to the scissors of different styles.

The upper surface of the first part is provided with a positioning groove, and the tip of the scissors can be placed in the positioning groove.

Note: the scissors can be positioned more accurately.

The cross-sectional area of the holding protrusion is gradually reduced from bottom to top.

Note: is beneficial to being inserted into the holes of the scissors handles.

The scissors fixing seats are the same in shape and size, the distances between every two adjacent scissors fixing seats are the same, and the fixing piece is arranged in the middle of the scissors fixing seats.

The scissors holder is connected with the mechanical arm through a flange plate.

Has the advantages that: the workman only need with waiting on the scissors of polishing puts into the mounting of scissors fixing base in proper order, and all the other processes can be handed over by mechanical automation and handle, improve the production automation level greatly.

Detailed Description

A scissors grinding robot workstation comprises a conveyor belt 5, a grinding robot and a grinding machine 1; a scissors fixing seat 51 is fixed on the conveying belt 5, and the grinding robot comprises a mechanical arm 2 and a scissors holder 3; the grinding robot sequentially grabs the scissors from the conveyor belt 5 according to a computer instruction, and moves the scissors to the grinding machine 1 for grinding. The scissors fixing seats 51 are uniformly distributed; the scissors fixing seat 51 is provided with a fixing part which is divided into two parts, the first part 511 is positioned at the tip end of the scissors and props against the scissors, the second part 512 is positioned below the scissors body and supports the scissors, the front end of the second part 512 is provided with a groove, the rear end of the second part 512 is provided with a supporting bulge, and the conveyor belt 5 is driven by the motor to rotate at a constant speed. Each joint of the mechanical arm 2 rotates according to computer instructions. The scissors holder 3 comprises an air cylinder 31 and an X-shaped holder 32, the left upper end of the X-shaped holder 32 is integrally connected with the shell of the air cylinder 3, the right upper end of the X-shaped holder 32 is fixedly connected with the telescopic end of the air cylinder 31, the lower end of the X-shaped holder 32 is provided with a holding plate, one holding plate is provided with a holding protrusion 321, and the holding protrusion 321 can be embedded into a hole of a scissors handle. The fixing member is detachable from the scissors fixing base 51. The first portion 511 has a detent on its upper surface into which the tips of the scissors can be inserted. The cross-sectional area of the grip protrusion 321 gradually decreases from bottom to top. The scissors fixing seats 51 are the same in shape and size, the distance between every two adjacent scissors fixing seats 51 is the same, and the fixing piece is arranged in the middle of the scissors fixing seats 51. The scissors gripper 3 is connected to the robot arm 2 via a flange.
