Referring to fig. 6, in an embodiment, the control module 60 includes an upper computer, and the upper computer is connected to the robot 20, the loading and unloading module 30, the clamping module 40 and the cutting module 50, and is respectively used for controlling the movement of the robot 20 and the movement of the first driving member 331 of the loading and unloading module 30, so as to take and discharge the material to and from the tool 200. Wherein the robot 20 is connected to the control module 60 and moves under the control of the control module 60. Meanwhile, the control module 60 receives the motion information of the manipulator 20 and controls the first driving element 331 of the loading and unloading module 30 to move, so as to load and unload the tool 200. The control clamping module 40 clamps the tool 200 to be machined or the control clamping module 40 releases the machined tool 200, and controls the cutting module 50 to cut the tool 200. In the cutting apparatus 100, in use, the cutter 200 is placed in a tray 300 provided on the loading/unloading table 11, and a plurality of trays 300 are stacked to prevent the trays from slipping.

The clamping mechanism 33 is driven by the manipulator 20 to move to the tray 300, the tool 200 is clamped by the pressing block 334 and the abutting piece 335, meanwhile, the fixing mechanism 42 is driven by the first sliding table 41 to move towards the direction away from the cutting module 50, the manipulator 20 drives the clamping mechanism 33 to move to the collet 4221, the machined tool 200 is clamped by the clamping mechanism 33 from the collet 4221, and meanwhile, the detection thimble is driven by the detection driving piece 4231 to move, so that whether the tool clamped by the collet 4221 is completely taken out is judged. The manipulator 20 drives the loading and unloading module 30 to move out, and the taken-out processed tool is put on the material tray 300 of the processed material level. Another clamping mechanism 33 places the green tool 200 into the collet 4221, and the collet 4221 clamps the green tool 200 under the drive of the clamping drive.

The cutting method of the cutting device 100 of the present application specifically includes the steps of:

s1, establishing a manipulator material taking coordinate system and a material placing coordinate system and setting a cutting reference of the tool to be machined, and moving the manipulator under the material taking coordinate system to drive the feeding and discharging module to clamp the tool to be machined and place the tool to be machined into the collet chuck;

specifically, a manipulator material taking coordinate system and a manipulator material discharging coordinate system are set according to a material level 111 of a material to be processed, a material level 112 of a processed material, and material trays respectively arranged on the material levels on the feeding and discharging worktable 11. The cutting reference of the cutter 200, that is, the length of the head part of the cutter 200 to be cut, is set, and the distance from the cutter 200 to the cutting element 52 by the first sliding table 41 is set, so that the reference is used for each cutting. The manipulator 20 drives the loading and unloading module 30 to move, the tool 200 to be machined is taken out from the tray 300 arranged on the material position to be machined through the clamping mechanism 33, the tool 200 to be machined is installed on the collet 4221, and the collet 4221 clamps the tool to be machined under the action of the clamping driving piece.

S2, the manipulator moves under the discharging coordinate system, the measuring mechanism measures the length of the tool to be machined, and the first sliding table drives the fixing mechanism to move to a preset distance;

specifically, the manipulator 20 moves under the feeding coordinate system and moves along the sliding direction of the first sliding table 41, when the contact block 343 contacts with the tool 200 to be processed, the manipulator 20 stops moving, the length of the tool 200 to be processed is determined according to the moving distance of the manipulator 20, and on the basis of the measured length, the first sliding table 41 moves toward the cutting module 50 according to the measured tool length of the tool to be processed and the preset tool cutting reference, so that the tool 200 to be processed is away from the cutting piece 52 by the preset distance.

S3, the cutting piece moves towards the feeding and discharging module to finish cutting;

specifically, the cutting element 52 moves towards the tool 200 to be machined under the driving of the second sliding table 51, so as to cut the tool 200.
