[0036] Second embodiment:

[0037] Based on the first embodiment, please refer to Figure 3 and Figure 4 , Figure 3 FIG. 1 is a schematic diagram of the installation structure of the rotating electrical machine of the second embodiment. Figure 4 It is a structural schematic diagram of the storage element of the second embodiment. The loading component 109 of this embodiment includes a first workbench 201, a lifting cylinder 202, a rotating motor 203, a mounting plate 204, a suction cup 205 and a storage element 206. The storage element includes a loading plate 207, a screw lift 208 and a limiting rod 209.

[0038] According to this specific embodiment, the storage element 206 is used to store stacked materials, and four suction cups 205 are provided on the mounting plate 204. The four suction cups 205 are arranged on both sides of the mounting plate 204 in a group of two, and the suction cups 205 are connected to the vacuum equipment. When working, the lifting cylinder 202 drives the rotating motor 203, the mounting plate 204 and the suction cups 205 to descend, so that the suction cups 205 can adsorb the materials, and then the lifting cylinder 202 is reset, and the rotating motor 203 drives the mounting plate 204 to rotate 180 degrees. At this time, the lifting cylinder 202 descends again and drives the rotating motor 203, the mounting plate 204 and the suction cups 205 to descend, so that the suction cups 205 place the adsorbed materials on the conveyor belt 103, and the two suction cups 205 on the other side descend to the material surface of the storage element 206, thereby adsorbing the next material, and so on and so forth to achieve continuous loading of materials.

[0039] Among them, the screw lift 208 is connected to the first workbench 201 and is arranged on the first workbench 201; the loading plate 207 is arranged on the screw lift 208 and is connected to the output end of the screw lift 208; the materials to be coded are stacked on the loading plate 207, and the loading plate 207 is driven to rise by the screw lift 208, thereby driving the materials on it to rise, so that the top layer of materials is always maintained at a suitable material taking height.

[0040] Secondly, the limiting rod 209 is fixedly connected to the first workbench 201 and is located on one side of the first workbench 201; there are multiple limiting rods 209, and the material is limited by multiple limiting rods 209 to prevent material deviation from affecting the suction of the suction cup 205.

[0041] Third embodiment:

[0042] Based on the first embodiment, please refer to Figure 5 and Figure 6 , Figure 5 2 is a schematic structural diagram of the guide plate of the second embodiment. Figure 6 It is a schematic diagram of the installation structure of the unloading cylinder of the second embodiment. The unloading component 110 of this embodiment includes a second workbench 301, a collecting seat 302 and a guiding component 303. The guiding component 303 includes a unloading cylinder 304, a guide plate 305 and a unloading plate 306.

[0043] According to this specific embodiment, the second workbench 301 is arranged on the side of the frame 101 away from the first workbench 201; the collecting seat 302 is fixedly connected to the second workbench 301 and is arranged on the second workbench 301; the guide component 303 is arranged on the second workbench 301.

[0044] Among them, the guide plate 305 is rotatably connected to the second workbench 301 and is arranged on the second workbench 301; the unloading cylinder 304 is rotatably connected to the second workbench 301, and the output end of the unloading cylinder 304 is rotatably connected to the guide plate 305; the unloading plate 306 is fixedly connected to the second workbench 301 and is arranged on the second workbench 301; the guide plate 305 is driven to rotate by the unloading cylinder 304. When the product coding is correct and the quality is good, the output end of the unloading cylinder 304 contracts. At this time, one side of the guide plate 305 contacts the conveyor belt 103, so that the material can flow into the collecting seat 302 through the guide plate 305; when it is detected that the product coding is incorrect, the unloading cylinder 304 extends. At this time, the defective products on the conveyor belt 103 fall on the unloading plate 306 and flow into the defective product pile along the unloading plate 306.

[0045] When the die-cutting assembly line code-jetting and code-reading device of the present invention is used, the screw lift 208 in the material storage element 206 drives the loading plate 207 to rise according to a preset program, so that the uppermost material reaches a suitable material-taking height; the lifting cylinder 202 of the loading component 109 drives the rotating motor 203, the mounting plate 204 and the suction cup 205 to descend. When the suction cup 205 descends to the surface of the material, the vacuum device is started to make the suction cup 205 adsorb the material. Then the lifting cylinder 202 resets and rises, and the rotating motor 203 drives the mounting plate 204 to rotate 180 degrees, and the adsorbed material is transferred to the top of the conveyor belt 103. At this time, the lifting cylinder 202 descends again, so that the suction cup 205 places the material steadily on the conveyor belt 103, and the two suction cups 205 on the other side immediately descend to the material surface of the material storage element 206 and start to adsorb the next material, thereby realizing continuous loading; the material moves on the conveyor belt 103 in its running direction. When the first photoelectric sensor 104 detects the material, it sends a signal to the control system. After receiving the signal, the control system controls the spray The coding component 108 is started, and the coding operation is performed on the surface of the material through the nozzle. The material after coding continues to move forward along the conveyor belt 103. When it reaches the area where the lens 106 and the light source 107 are located, the second photoelectric sensor 105 detects the material and feeds back a signal to the control system, triggering the lens 106 to capture high-definition images of the coding content on the surface of the material. The image data collected by the lens 106 is transmitted to the visual inspection system. The visual inspection system uses an algorithm based on deep learning to perform character recognition, QR code decoding, coding integrity detection, coding position detection and other operations on the coding content to determine whether the coding information is complete and accurate; if it is detected that the material coding quality is qualified, the control system controls the output end of the unloading cylinder 304 of the unloading component 110 to retract, and the material can flow into the collection seat 302 along the guide plate 305; if it is detected that the product coding is incorrect, the unloading cylinder 304 extends, and the defective products on the conveyor belt 103 fall on the unloading plate 306 and flow into the defective product pile along the unloading plate 306, thereby realizing automatic separation of qualified products and unqualified products.

[0046] The present invention also includes a die-cutting assembly line type code spraying and reading system, which is applied to the die-cutting assembly line type code spraying and reading equipment.
