[0019] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes. Example 1

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 A schematic structural diagram of a first embodiment of a recognition device based on AI visual technology provided by the present invention; Figure 2 for Figure 1 The structural diagram of the cabinet from another perspective is shown; Figure 3 for Figure 1 A schematic diagram of the top plate structure shown; Figure 4 for Figure 1 The schematic diagram of the protective frame structure shown; Figure 5 for Figure 1 The front section structure diagram of the cabinet shown; Figure 6 for Figure 4 An enlarged schematic diagram of part A is shown. An identification device based on AI visual technology comprises: a cabinet 1, a first drive motor 11 is fixedly installed at the bottom of the cabinet 1, a screw rod 12 is fixedly installed at the output end of the first drive motor 11, a moving plate 13 is threadedly connected to the outer side of the screw rod 12, and support rods 14 are fixedly installed around the top of the moving plate 13; A conveying assembly 2, wherein the conveying assembly 2 is fixedly installed on the top of the cabinet 1; A top plate 3, wherein the top plate 3 is fixedly mounted on the top of the support rod 14, an industrial camera 31 is fixedly mounted on the bottom of the top plate 3, an AI visual recognition host 38 is fixedly mounted on the top of the top plate 3, a rotation groove 32 is opened at one end of the top plate 3, a rotating shaft 33 is fixedly mounted on the inner side of the rotating groove 32, a blocking plate 34 is rotatably connected to the outer side of the rotating shaft 33, a control switch 37 is arranged on the top of the blocking plate 34, a support frame 36 is fixedly mounted on the top of the control switch 37, and the bottom of the support frame 36 is fixedly mounted on the top of the top plate 3; A protective frame 4 is arranged at the bottom of the top plate 3, and sliding frames 41 are fixedly installed on both sides of the protective frame 4, a second driving motor 42 is fixedly installed on one end of one sliding frame 41, and a reciprocating screw 43 is fixedly installed on the output end of the second driving motor 42, and a sliding rod 44 is fixedly installed on the inner side surface of the other sliding frame 41, and a moving frame 45 is arranged at the bottom of the protective frame 4, one end of the moving frame 45 is threadedly connected to the outer side surface of the reciprocating screw 43, and the other end of the moving frame 45 is slidably connected to the outer side surface of the sliding rod 44, and a mounting plate 46 is fixedly installed on the top of the mounting plate 46, and a spraying frame 47 is fixedly installed on the top of the spraying frame 47, and a wiping sponge 48 is arranged on the top of the spraying frame 47.

[0021] When in use, when it is necessary to detect objects of different heights, the user can start the first drive motor 11, so that the first drive motor 11 drives the lead screw 12 to be threadedly connected inside the movable plate 13, thereby adjusting the height of the movable plate 13, and through the setting of the support rod 14, the top plate 3 can be driven to adjust the height, so that the height of the industrial camera 31 can be adjusted, so as to detect objects of different heights and increase the adaptability of the device; The conveying component 2 is fixedly installed on the top of the cabinet 1. It is mainly responsible for conveying the goods to be inspected. It plays a role of transportation in the entire inspection process to ensure that the goods can enter the inspection area smoothly. The industrial camera 31 is responsible for capturing the product image and is an important detection component of the entire recognition device. The AI ​​visual recognition host 38 receives the image captured by the industrial camera 31, analyzes and recognizes it, and obtains the detection result. A rubber pad 35 is fixedly installed on one side of the blocking plate 34. The presence of the rubber pad 35 can play a buffering role when the blocking plate 34 collides with the super-high product, thereby reducing damage to the product and the blocking plate 34 itself. The industrial camera 31 uses a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS) image sensor to capture images. When the detected object is within the shooting field of view of the industrial camera 31, light passes through the protective frame 4 to irradiate the surface of the object, and the reflected light from the surface of the object enters the lens of the industrial camera 31. The lens focuses the light on the image sensor, and the pixels in the image sensor generate corresponding electrical signals according to the received light intensity. For the CCD sensor, these electrical signals are internally charged and amplified. The CMOS sensor directly converts the optical signal into an electrical signal at each pixel and performs digital processing. After a series of processing, the image sensor converts these electrical signals into digital image data and outputs them in a specific image format (such as common BMP, JPEG, etc.). The industrial camera 31 transmits the collected digital image data to the AI ​​visual recognition host 38 through a data transmission interface (such as USB, GigE, etc.) to provide raw data for subsequent analysis and recognition. After receiving the image data transmitted by the industrial camera 31, the AI ​​visual recognition host 38 uses computing power and pre-trained deep learning models or other image processing algorithms to perform analysis and recognition. The deep learning model usually uses a convolutional neural network (CNN), which consists of multiple convolutional layers, pooling layers, and fully connected layers. In the model training phase, a large amount of image data with labeled information (such as the category, size, defect characteristics, etc. of the object) is used to train the CNN model. During the training process, the model continuously adjusts the weights of each neuron in the network to learn the relationship between different features in the image and the labeled information. When the training is completed, the model has the ability to extract features and classify the input image. In practice, When working, the AI ​​visual recognition host 38 inputs the image data transmitted by the industrial camera 31 into the trained model; the convolution layer of the model automatically extracts various features in the image, such as edges, textures, shapes, etc.; the pooling layer compresses and reduces the dimension of the extracted features, reducing the amount of data while retaining key features; after multiple layers of convolution and pooling operations, the fully connected layer will classify and judge according to the extracted features, and output the recognition results of the objects in the image, such as whether the items are qualified, which category of products they belong to, whether there are defects, and the type and location of the defects; the recognition results can be displayed on the display screen, and can also be output to other devices or systems for subsequent processing, such as controlling the sorting device to remove unqualified products; The protective frame 4 is arranged at the bottom of the top plate 3, which plays a protective role for the industrial camera 31 and reduces the impact of external factors on the industrial camera 31; sliding frames 41 are fixedly installed on both sides of the protective frame 4, and a second drive motor 42 is fixedly installed at one end of one slide frame 41, and the second drive motor 42 serves as a power source for the cleaning mechanism; a reciprocating screw rod 43 is fixedly installed at its output end, and a slide rod 44 is fixedly installed on the inner side surface of the other slide frame 41. A moving frame 45 is arranged at the bottom of the protective frame 4, and one end of the moving frame 45 is threadedly connected to the outer side surface of the reciprocating screw rod 43, and the other end is slidably connected to the outer side surface of the slide rod 44. This structure enables the moving frame 45 to perform reciprocating linear motion along the reciprocating screw rod 43 and the slide rod 44 under the drive of the second drive motor 42.

[0022] The top of the screw rod 12 is rotatably connected to the top of the inner side of the cabinet 1 , the movable plate 13 is arranged on the inner side of the cabinet 1 , and the support rod 14 is slidably connected to the inside of the top of the cabinet 1 .

[0023] A rubber pad 35 is fixedly mounted on one side of the blocking plate 34 .

[0024] The top of the wiping sponge 48 abuts against the bottom of the protection frame 3, and the protection frame 3 is made of transparent material.

[0026] A fixing frame 5 is fixedly mounted on one side of the water tank 6 , and a push switch 51 is fixedly mounted on one side of the fixing frame 5 . The push switch 51 is arranged on a side of the spray frame 47 .

[0028] When in use, the spray frame 47 is used to spray cleaning liquid; the protective frame 4 is made of transparent material, which does not affect the shooting of the industrial camera 31 and allows the wiping sponge 48 to clean its bottom; the water tank 6 is used to store cleaning liquid; the cleaning liquid in the water tank 6 is transported to the spray frame 47 through the water pipe 62 by the pump body 61; the push switch 51 and the pump body 61 are electrically connected. When the push switch 51 is pressed once on one side of the spray frame 47, the pump body 61 will start once to transport the cleaning liquid to the inside of the spray frame 47, and then spray it to the inside of the wiping sponge 48 through the water outlet at the top, thereby cleaning the protective frame 4.

[0029] The working principle of the recognition device based on AI vision technology provided by the present invention is as follows: The commodity to be inspected is placed on the conveyor assembly 2, and the conveyor assembly 2 drives the commodity to move. When the commodity moves to the inspection area, if the commodity is at a normal height and does not touch the blocking plate 34, the industrial camera 31 takes an image of the commodity and transmits the image to the AI ​​visual recognition host 38 for analysis and identification. If the commodity is too high and touches the blocking plate 34, the blocking plate 34 rotates around the rotating shaft 33, triggering the control switch 37. The control switch 37 can control the conveyor assembly 2 to stop running to prevent the commodity from continuing to move and colliding with the inspection equipment. When it is necessary to clean the bottom of the protective frame 4, start the second drive motor 42, the second drive motor 42 drives the reciprocating screw 43 to rotate, the movable frame 45 moves left and right under the action of the reciprocating screw 43 and the sliding rod 44, and the mounting plate 46 and the spray frame 47 move accordingly, and the wiping sponge 48 wipes the bottom of the protective frame 4. At the same time, press the push switch 51, the pump body 61 starts, and the cleaning liquid in the water tank 6 is transported to the spray frame 47 through the water pipe 62, and sprayed to the bottom of the protective frame 4, and cleaned with the wiping sponge 48.

In this way, the industrial camera 31 can be protected, the industrial camera 31 can be prevented from being damaged by collision, and the service life of the industrial camera 31 can be increased; In addition, by covering the outer side of the industrial camera 31 with a protective frame 4 and regularly starting the second driving motor 42, the movable frame 45 is driven to drive the wiping sponge 48 to clean the dust at the bottom of the protective frame 4, thereby avoiding dust accumulation and increasing the recognition effect of the industrial camera 31.
