[0026] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides an automatic sorting device based on visual recognition, which is used for an automatic sorting device, comprising: a sorting mechanism 1, a screening mechanism 2 is arranged on the bottom side of the sorting mechanism 1;
[0027] The sorting mechanism 1 includes two support plates 101, a group of guide rollers 102 are movably inserted between the opposite sides of the two support plates 101, a transmission belt 103 is connected between the outer walls of the group of guide rollers 102, a first motor 104 is fixedly installed on one side of the outer wall of one of the two support plates 101, and the output end of the first motor 104 is fixedly connected to one end of the outer wall of one of the guide rollers 102, a U-shaped frame 105 is fixedly installed on the top of the two support plates 101, and a color A color sensor 106 and a PLC controller 107 are fixedly installed on the top of the U-shaped frame 105, and the PLC controller 107 is electrically connected to the color sensor 106. An L-shaped frame 108 is fixedly installed on one side of the outer wall of the two support plates 101, and a second motor 109 is fixedly installed on one side of the outer wall of the L-shaped frame 108. A rotating shaft 110 is movably inserted into the inner wall of the L-shaped frame 108, and one end of the outer wall of the rotating shaft 110 is fixedly connected to the output end of the second motor 109, and a rotating plate 111 is fixedly installed on the top of the rotating shaft 110.
[0028] The working principle here is: starting the first motor 104 will drive the guide roller 102 to rotate, and then drive the conveyor belt 103 to rotate. When the conveyor belt 103 rotates, it can drive the lychees to be transported forward. During the transportation process, the color sensor 106 will identify the color of the lychees, and then transmit the identified information to the PLC controller 107. The PLC controller 107 will control the second motor 109 according to the set information. If the color meets the standard, the second motor 109 will be controlled to rotate forward, and the rotating plate 111 will tilt to the right, and the qualified products will fall into the screening mechanism 2 at the bottom. If the color does not meet the standard, the second motor 109 will be controlled to rotate reversely, and the rotating plate 111 will tilt to the left, thereby achieving the purpose of sorting.
[0029] Embodiment 2, as Figure 1-Figure 4 As shown, the screening mechanism 2 includes a screening box 201, two groups of springs 202 are fixedly installed at the bottom of the screening box 201, and bottom plates 203 are fixedly installed at the bottoms of the two groups of springs 202. Two sieve plates 204 are arranged on the inner surface wall of the screening box 201, and a vibration motor 205 is fixedly installed on one side of the outer wall of the screening box 201. A defective box 112 is arranged at the bottom of the two support plates 101, and the defective box 112 is located at the bottom of the rotating plate 111. A group of anti-roll grooves 113 are arranged on the outer surface wall of the conveyor belt 103, and each anti-roll groove 113 The distances between them are equal, two limit plates 114 are fixedly installed on the top of the two support plates 101, and each two limit plates 114 are respectively located on both sides of the outer wall of the U-shaped frame 105, a water tank 115 is fixedly installed on the bottom of the two support plates 101, a pump 116 is fixedly connected to the bottom of the water tank 115, and a nozzle 117 is fixedly connected to the output end of the pump 116, a water injection end 118 is arranged on the top of the water tank 115, a top cover 119 is arranged on the top of the water injection end 118, and the screening box 201 is arranged at the bottom of the L-shaped frame 108.
[0030] The working principle here is: when the vibration motor 205 is started, vibration will be emitted. Since a spring 202 is provided at the bottom of the screening box 201, the vibration motor 205 will drive the screening box 201 to vibrate when vibrating. At this time, the lychees in the sieve plate 204 can be screened, and the smaller lychees will be screened from the top sieve plate 204 to the bottom sieve plate 204, thereby achieving the purpose of screening the size of the lychees. The lychees that do not meet the color standards will be collected in the defective box 112. The anti-roll groove 113 can prevent the lychees from rolling, and the limit plate 114 can prevent the lychees from rolling off the conveyor belt 103. When the pump 116 is started, the cleaning water in the water tank 115 will be drawn and then sprayed out through the nozzle 117. The sprayed cleaning water can be used to rinse the lychees. Open the top cover 119 and add flushing water to the water tank 115 through the water injection end 118.
[0031] Working principle: When in use, put the lychees on the conveyor belt 103, start the first motor 104, which will drive the guide roller 102 to rotate, and then drive the conveyor belt 103 to rotate. When the conveyor belt 103 rotates, it can drive the lychees to be transported forward, and the anti-roll groove 113 is set on the conveyor belt 103 to prevent the lychees from rolling around and causing damage to the lychees. During the transportation process, the color sensor 106 will identify the color of the lychees, and then transmit the identified information to the PLC controller 107. The PLC controller 107 will control the second motor 109 according to the set information. If the color meets the standard, the second motor 109 will be controlled to rotate forward, and the rotating plate 111 will tilt to the right, and the qualified products will fall into the screening mechanism 2 at the bottom. When the vibration motor 205 is started, vibration will be emitted. Since a spring 202 is provided at the bottom of the screening box 201, the vibration motor 205 will drive the screening box 201 to vibrate when vibrating. At this time, the lychees in the sieve plate 204 can be screened, and the smaller lychees will be screened from the top sieve plate 204 to the bottom sieve plate 204, thereby achieving the purpose of screening the size of the lychees. Then, the pump 116 is started to draw the cleaning water in the water tank 115 and then spray it through the nozzle 117. The sprayed cleaning water can rinse the lychees. If the color does not meet the standard, the second motor 109 will be controlled to reverse, and the rotating plate 111 will tilt to the left. The lychees that do not meet the standard will fall into the defective box 112 for collection. In summary, the problems raised in the above background are solved.
