This testing equipment is widely used in food processing plants, catering companies and other places. In actual applications, steamed bun testing equipment usually requires the use of the following technologies:

After the image recognition algorithm is used to determine that a certain steamed bun has a problem, a signal will be sent to the display 2, and the display 2 will accurately calculate the time when the water pump 18 needs to be started according to the moving speed and distance of the steamed bun, so as to ensure that the ink is accurately The water pump 18 squeezes the ink from the ink cartridge 21 at a certain pressure through the two connecting pipes 26 to form a continuous ink flow, which is sprayed onto the surface of the steamed buns through the nozzle 19 to mark them. The ink is food-grade safe ink to ensure safety and harmlessness. In the large-scale production of steamed buns inspection process, a large number of steamed buns flow quickly on the conveyor belt 3. By marking the steamed buns with problems through inkjet, the staff or subsequent automated sorting equipment can quickly identify the steamed buns with problems without careful inspection one by one, which greatly improves the sorting speed and effectively improves the overall product quality.

In addition, the rotation of the camera can adjust the incident angle of light, so that the light on the surface of the steamed buns is more uniform, reducing shadows and reflections, thereby improving image quality.

[0032] Working principle:

[0033] In the first step, the steamed buns are placed on the conveyor belt 3, and the steamed buns are separated into two groups for transportation by a group of partitions 4 to prevent them from overlapping and affecting subsequent inspection. The high-definition camera 5 is started through the display 2 to take pictures of the steamed buns, and then the appearance characteristics of the steamed buns are analyzed through the image recognition algorithm. The inspection content includes whether the shape is regular, whether there is collapse, deformation, etc., whether the skin is intact, whether there is damage, cracks, etc., whether the color is uniform, and whether there is obvious discoloration, spots or burnt areas. During the inspection process, the motor 22 is started by controlling the display 2. When the motor 22 receives the signal, its output shaft will drive the connecting roller fixed to it to rotate, and the connecting roller will drive the connecting roller fixed to it to rotate during the rotation process. The two connecting blocks 7 are movably connected to the conveyor frame 1 through two pulleys 23 fixed thereunder. At this time, the two connecting blocks 7 and the high-definition camera 5 are driven to move. At this time, the high-definition camera 5 moving in parallel can dynamically track the steamed buns and always maintain a suitable shooting position to ensure that a complete and clear image can be obtained during the movement of the steamed buns. In the case of large-scale production, continuous dynamic detection can quickly process a large number of steamed buns, ensure product quality without affecting production progress, and help improve the accuracy and efficiency of steamed bun detection.

[0034] In the second step, after using the image recognition algorithm to determine that a certain steamed bun has a problem, a signal will be sent to the display 2, and the display 2 will accurately calculate the time when the water pump 18 needs to be started according to the moving speed and distance of the steamed bun, ensuring that the ink is accurately sprayed out when the steamed bun reaches a specific position. The water pump 18 squeezes the ink from the ink cartridge 21 at a certain pressure through two connecting tubes 26 to form a continuous ink flow, which is sprayed onto the surface of the steamed bun through the nozzle 19 to mark it. The ink is food-grade safe ink to ensure safety and harmlessness. In the large-scale production of steamed buns, a large number of steamed buns flow quickly on the conveyor belt 3. By marking the steamed buns with problems by inkjet, the staff or subsequent automated sorting equipment can quickly identify the steamed buns with problems without having to carefully check them one by one, which greatly improves the sorting speed and effectively improves the overall product quality.

[0035] The third step is to start the limit block 24 by controlling the display 2 during the detection process. When the limit block 24 receives the signal, its output shaft will drive the pulley 23 fixed thereto to rotate. During the rotation process, the pulley 23 will drive the fixed box 6 fixed thereto to rotate together. During the rotation process, the fixed box 6 will drive the high-definition camera 5 fixed thereon to rotate. The high-definition camera 5 that can move and rotate in parallel can shoot the steamed buns from different angles, thereby fully displaying the appearance characteristics of the steamed buns. In addition, the rotation of the camera can adjust the incident angle of light, so that the lighting on the surface of the steamed buns is more uniform, reducing shadows and reflections, thereby improving image quality.

Many modifications and variations will be apparent to those of ordinary skill in the art.
