The slide track 410 may be a "T" shaped structure to facilitate the confinement of the collection trough 210, the cutting structure 220, the tool post 240, and the robotic arm 300.
The blade collection assembly 200 includes a collection trough 210, a cutting structure 220, a drive structure 230, a blade holder 240, and a plurality of different blade types 250.
The collection trough 210, tool post 240, and cutting structure 220 are all mounted to the same slide rail 410, and the collection trough 210 and cutting structure 220 are able to move along the slide rail 410. The blade carrier 240 is mounted between the collection trough 210 and the cutting structure 220, and when the collection trough 210 and the cutting structure 220 are close to each other, the cutting structure 220 can push the blade 250 of the blade carrier 240 to extend into the collection trough 210, so as to cut the blade from the plant.
The movement of the collection trough 210 and the cutting device is controlled by a drive structure 230. The driving structure 230 includes a first motor 231, a first link 232, a second link 233, and a third link 234. The first motor 231 can drive the first link 232 to rotate, and the second motor 260 is connected to the middle position of the first link 232, and meanwhile, the first link 232 is also rotatably connected to the working platform 400.

The rotational plane of the first link 232, the rotational plane of the second link 233, and the rotational plane of the third link 234 are parallel to each other. When the first link 232 rotates from the horizontal direction to the vertical direction, the collecting groove 210 and the cutting device approach each other under the pulling of the second link 233 and the third link 234; when the first link 232 rotates from the vertical direction to the horizontal direction, the collecting tank 210 and the cutting device are pushed away from each other by the second link 233 and the third link 234.
The cutting structure 220 comprises a cutting seat 221 and a push rod 222, wherein the cutting seat 221 is slidably connected with the slide rail 410, and the push rod 222 is installed on the cutting seat 221. A cutting hole 211 for cooperating with the blade 250 is provided on the collecting groove 210.
The blade capture assembly 200 operates in the following specific manner:
initially the first link 232 is arranged horizontally, the collection gutter 210 and the cutting structure 220 being separated from each other; after the blade is sent into the collecting tank 210 by the mechanical arm 300, the first motor 231 controls the first link 232 to rotate in the forward direction, at this time, the first link 232 rotates from the horizontal state to the vertical state, the collecting tank 210 and the cutting structure 220 approach each other, during the process that the collecting tank 210 and the cutting structure approach each other, the push rod 222 pushes the blade 250 down from the tool rest 240, and then the blade 250 moves towards the collecting tank 210 along with the push rod 222; when the first link 232 is rotated to the vertical state, the blade 250 is inserted into the cutting hole 211 on the collecting tank 210, and the blade is cut off from the plant; after the cutting is completed, the first motor 231 drives the first link 232 to rotate in the opposite direction, so that the blade 250 exits from the range of the collecting tank 210, and the blade collection operation is completed.
During the withdrawal of the blade 250 from the collection trough 210, the blade 250 snaps back onto the blade holder 240 as the push rod 222 passes the blade holder 240.
Specifically, the tool holder 240 may be configured in a circular shape, a plurality of mounting holes 241 are provided along a circumferential direction of the tool holder 240, and different types of inserts 250 are respectively mounted in the different mounting holes 241. In use, the blade holder 240 is simply rotated so that the desired blade 250 is positioned in the path of travel of the pusher bar 222.
Of course, the circular shape of the blade holder 240 is only one embodiment of the present embodiment, and in other embodiments, the blade holder 240 may be configured in a bar shape, and the blade 250 may be switched by moving the blade holder 240 in the lateral direction.
One of the blade holder 240 and the blade 250 is magnetic, the other is made of metal, and the material of the cutting structure 220 is the same as that of the blade holder 240. The mounting hole 241 is a through hole, the blade 250 and the blade holder 240 are attracted together by magnetic force, when the push rod 222 passes through the mounting hole 241, the blade 250 is pushed out of the mounting hole 241 by the push rod 222, and the blade 250 and the push rod 222 form a magnetic connection, so that the blade 250 is prevented from falling off the push rod 222; as the push rod 222 moves back, the blade 250 re-engages the blade holder 240.
In some embodiments of the present embodiment, the diameter of the mounting hole 241 towards one end of the collecting groove 210 may be larger than the diameter of the mounting hole 241 towards one end of the cutting structure 220, and the diameter of the push rod 222 is the same as the smallest diameter of the mounting hole 241. This enables the blade 250 to be pushed down from the blade holder 240 as the push rod 222 moves towards the collection trough 210; when the push rod 222 moves in a direction away from the collecting groove 210, the bottom of the blade 250 abuts against the small end of the mounting hole 241 when the push rod 222 passes through the tool holder 240, so that the blade 250 is prevented from being always adsorbed on the push rod 222. Of course, by providing the shape of the mounting hole 241 is only one embodiment, and in other embodiments, the magnetic attraction of the blade holder 240 to the blade 250 may be greater than the magnetic attraction of the push rod 222 to the blade 250 to ensure that the blade 250 is attracted to the blade holder 240 when the push rod 222 is withdrawn from the blade holder 240.
When tool holder 240 is configured in a circular shape, the rotation of tool holder 240 can be controlled by a second motor 260 and gear set 270. Specifically, the second motor 260 is mounted on the working platform 400, the second motor 260 is connected with one gear of the gear set 270, the tool holder 240 is connected with the other gear of the gear set 270, and the second motor 260 and the gear set 270 can be used for accurately controlling the rotation angle of the tool holder 240, so that the fast and accurate switching of the blade 250 is realized.
