DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Please refer to Figures 1 to 5, A visual recognition device, including a printing device body 1, on which a display screen 2 and a paper outlet 3 are provided. At the upper end of the inner wall of the paper outlet 3, two symmetrically arranged L-shaped support plates 4 are fixedly connected. The ends of the two L-shaped support plates 4 are fixedly connected with a baffle 5. A through hole is provided on the right L-shaped support plate 4. A camera 6 is slidably connected to the two symmetrically arranged L-shaped support plates 4. The right side of the L-shaped support plate 4 is connected with a charging cable 7 for charging the camera 6. The front end of the right L-shaped support plate 4 is fixedly connected with a first connecting seat 8, and the front end of the left L-shaped support plate 4 is fixedly connected with a second connecting seat 9. A fixing mechanism 10 is rotatably connected to the second connecting seat 9.

[0020] As Figures 1 to 5 shown, when the visual recognition device in the present utility model is in use, first slide the camera 6 onto the two symmetrically arranged L-shaped support plates 4, then connect the charging cable 7 to the camera 6. Then pull the front end of the L-shaped hook 1005 outwards. The L-shaped hook 1005 drives the inner rod 1004 to move outwards along the sliding cavity 1002, and the spring 1003 is stretched and stores energy. At the same time, rotate the L-shaped hook 1005 upwards so that the upper surface of the inner rod 1004 is in contact with the connecting rod 801. Slowly release the L-shaped hook 1005, and the spring 1003 releases energy, driving the inner rod 1004 to move inwards along the sliding cavity 1002 until the L-shaped hook 1005 is hung on the connecting rod 801, then the camera 6 can be fixed. By performing the opposite operation, the camera 6 can be removed for maintenance and replacement. When printing a product, input the content to be printed on the display screen 2, start the printing device, and the LED light strip 11 lights up. First, print one product. After manually checking that the product is correct, use the camera 6 to take a photo of it and store the taken photo in the system as a reference picture. Then continue to print other products. After each product is printed, the camera 6 will automatically take a photo of it and compare the taken product with the reference picture stored in the system. Those identified as OK will proceed to the next process, and those identified as NG will quickly feedback a signal to the host and stop the printing work to reduce the production of defective products. It should be noted that: a processor is provided inside the printing device body 1. The processor is electrically connected to the camera 6 and also electrically connected to the display screen 2. The processor is used to process and compare the image data taken by the camera 6. If there are problems such as blurring or black spots, it will be prompted through the display screen 2, thus replacing manual inspection. The processing process of the processor is similar to the processing process of a method, system, and mobile terminal for preventing wrong filling of information with the publication number CN104834924B.

[0021] As Figure 2 shown, LED light strips 11 are fixedly connected to both sides of the two L-shaped support plates 4.

[0022] Specifically, the LED light strip 11 improves the brightness at the paper outlet 3, making the photographing effect of the camera 6 better.

[0023] As Figure 5 shown, the first connecting seat 8 includes a connecting rod 801 fixedly connected to the front end of the right L-shaped support plate 4, and a limiting block 802 is fixedly connected to the front end of the connecting rod 801.

[0024] Specifically, the connecting rod 801 is used to connect with the L-shaped hook 1005 on the fixing mechanism 10.

[0025] As Figure 4 shown, the structure of the second connecting seat 9 is the same as that of the first connecting seat 8, and the position of the second connecting seat 9 is lower than that of the first connecting seat 8.

[0026] Specifically, the fixing mechanism 10 can rotate through the outer rod 1001 rotatably connected thereto. When the fixing mechanism 10 is in a horizontal state, the inner rod 1004 can be attached to the connecting rod 801 on the first connecting seat 8.

[0027] As Figure 5 shown, the fixing mechanism 10 includes an outer rod 1001. A sliding cavity 1002 is formed at the front end of the outer rod 1001. A spring 1003 is fixedly connected to the inner wall of the sliding cavity 1002. The output end of the spring 1003 is fixedly connected to an inner rod 1004, and an L-shaped hook 1005 is fixedly connected to the front end of the inner rod 1004.

[0028] Specifically, after the camera 6 slides into the two symmetrically arranged L-shaped support plates 4, the charging cable 7 is connected to the camera 6. Then, the front end of the L-shaped hook 1005 is pulled outward. The L-shaped hook 1005 drives the inner rod 1004 to move outward along the sliding cavity 1002, and the spring 1003 is stretched and stores energy. At the same time, the L-shaped hook 1005 is rotated upward so that the upper surface of the inner rod 1004 is attached to the connecting rod 801. The L-shaped hook 1005 is slowly released, and the spring 1003 releases energy, driving the inner rod 1004 to move inward along the sliding cavity 1002 until the L-shaped hook 1005 is hooked on the connecting rod 801, and then the camera 6 can be fixed. By operating in the reverse manner, the camera 6 can be removed for repair and replacement.
