[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-6 , the present invention provides a technical solution: a machine recognition visual detection device capable of surrounding movement, including a workbench 10, a motor 20, a rotating shaft 201, a belt 202, a placement groove 203, a sleeve 204, a threaded rod 205, a detection head 206, a telescopic rod 207, a first spring 30, a placement plate 301, a suction cup 302, a gravity sensor 303, a vertical plate 304, an electromagnet 305, a pressing plate 306 and a second spring 307;

[0032] This machine recognition visual detection device can fix the position of the recognition target to prevent the position of the recognition target from shifting. The specific implementation method is as follows:

[0033] A limiting mechanism is arranged on the surface of the workbench 10, and the limiting mechanism includes: a first spring 30 is installed on the inner bottom surface of the placement groove 203, and the other end of the first spring 30 is connected to the placement plate 301. A gravity sensor 303 is embedded in the inner bottom surface of the placement groove 203, and suction cups 302 are arranged around the inner bottom surface of the placement groove 203. A vertical plate 304 is fixedly connected to the surface of the workbench 10, and an electromagnet 305 is installed at the top of the vertical plate 304. A pressing plate 306 is slidably installed on the surface of the vertical plate 304, and a second spring 307 is connected between the pressing plate 306 and the vertical plate 304. An opening is arranged on the surface of the placement plate 301, and the opening of the placement plate 301 corresponds to the position of the suction cup 302, and the suction cup 302 is slidably connected to the placement plate 301. The vertical plate 304 and the pressing plate 306 are slidably connected, the pressing plate 306 corresponds to the position of the placement groove 203, and the placement groove 203 and the placement plate 301 are slidably connected, and the bottom of the placement plate 301 is in contact with the surface of the gravity sensor 303.

[0034] Place the recognition target inside the placement slot 203. At this time, the bottom of the recognition target lands on the surface of the placement plate 301. Due to the gravity of the recognition target, the placement plate 301 moves downward, and the end of the placement plate 301 presses against the first spring 30, causing the first spring 30 to contract. At the same time, the placement plate 301 drives the opening towards the suction cup 302, causing the end of the suction cup 302 to leak out from above the opening of the placement plate 301. At this time, the end of the suction cup 302 is in contact with the bottom of the recognition target. At this time, the air between the suction cup 302 and the recognition target is discharged, and at this time, the recognition target can be fixed by the suction cup 302. At the same time, the end of the placement plate 301 presses against the gravity sensor 303. The gravity sensor 303 is under pressure, and the gravity sensor 303 controls the electromagnet 305 to turn on, causing the end of the electromagnet 305 to pop out. The end of the electromagnet 305 pushes the pressing plate 306 downward, causing one end of the pressing plate 306 to move downward inside the vertical plate 304. At this time, the end of the pressing plate 306 moves to the surface of the recognition target, and the recognition target can be fixed between the pressing plate 306 and the placement plate 301. At the same time, the pressing plate 306 presses downward on the second spring 307, causing the second spring 307 to contract.

[0035] This machine recognition vision detection device improves the detection range of the detection head 206. The specific implementation method is as follows:

[0036] The workbench 10 is set as a hollow cylindrical structure, and a motor 20 is installed on the inner bottom surface of the workbench 10; a rotating mechanism is arranged on the surface of the workbench 10, and the rotating mechanism includes: the end of the output shaft of the motor 20 is fixedly connected with a rotating shaft 201, and a belt 202 is sleeved on the surface of the rotating shaft 201. The end of the rotating shaft 201 penetrates through the surface of the workbench 10 and is fixedly connected with a placement slot 203. A threaded rod 205 is rotatably installed inside the workbench 10, and a sleeve 204 is sleeved on the surface of the threaded rod 205, and a detection head 206 is connected to the surface of the sleeve 204. A telescopic rod 207 is connected to the surface of the workbench 10, and the other end of the telescopic rod 207 is connected to the surface of the detection head 206. The rotating shaft 201 is rotatably connected to the workbench 10, and the bottom surface of the workbench 10 is rotatably connected to the placement plate 301. Threads are provided inside the sleeve 204, and the sleeve 204 is threadedly connected to the threaded rod 205, and the threaded rod 205 is rotatably connected to the workbench 10. The bottom of the threaded rod 205 is set as a smooth plane, and a belt 202 is sleeved on the bottom surface of the threaded rod 205. The detection head 206 is arranged on one side of the placement slot 203.

[0037] After the recognition target is fixed, the motor 20 is started. The output shaft of the motor 20 drives the rotating shaft 201 to rotate. The rotating shaft 201 drives the placement groove 203 on the surface to rotate. The placement groove 203 drives the internal recognition target to rotate, causing the recognition target to rotate under the bottom of the pressing plate 306 and simultaneously driving the recognition target to rotate on one side of the detection head 206. When the rotating shaft 201 rotates, the belt roller on the surface of the rotating shaft 201 and the belt 202 drive the belt roller at the bottom of the threaded rod 205 to rotate. At this time, the threaded rod 205 rotates inside the workbench 10. At this time, the sleeve 204 moves up or down along the thread on the surface of the threaded rod 205. At this time, the sleeve 204 drives the detection head 206 to move, causing the detection head 206 to rotate in the vertical direction to detect the recognition target. At the same time, when the detection head 206 moves, it drives the telescopic rod 207 to extend or contract, so that the telescopic rod 207 limits the detection head 206.

[0038] Working principle: When using this machine vision detection device with a circumferential movement function, the rotating shaft 201, belt 202, placement groove 203, sleeve 204 and threaded rod 205 are provided to increase the detection range of the detection head 206. The suction cup 302, gravity sensor 303, electromagnet 305, pressing plate 306 and spring two 307 are provided to fix the position of the recognition target, prevent the position of the recognition target from shifting, and increase the overall practicality.
