[0016] Compared with the prior art, the present invention has the following advantages and positive effects.

[0017] 1. The present invention is provided with a marking component and a loading and unloading robot component. The first suction cup component and the second suction cup component in the loading and unloading robot component are used for automatic loading and unloading of products to the fixed suction cup. The loading, unloading and fixed suction cups are arranged in a straight line, so that the transfer of products is arranged in a straight line with the shortest distance, saving transportation time and improving work efficiency. The fixed suction cup moves longitudinally relative to the positioning frame, and the marking gun moves laterally relative to the positioning frame, so that the marking gun can print the entire surface area of ​​the product in both longitudinal and transverse dimensions. After printing is completed, the second suction cup component is used for unloading. The whole process can be completed automatically with a high degree of automation, without manual participation, reducing labor intensity and improving work efficiency.

[0018] 2. Setting the loading assembly and unloading assembly with the same structure can reduce processing costs, facilitate inventory, and reduce later maintenance costs. The loading assembly and unloading assembly are symmetrically arranged relative to the fixed suction cup, and the structure is compact. The loading assembly is arranged correspondingly to the first suction cup assembly, and the unloading assembly is arranged correspondingly to the second suction cup assembly. The symmetrical structure satisfies the condition of synchronous movement of the first suction cup assembly and the second suction cup assembly, so that unloading can be carried out at the same time as loading, saving waiting time, shortening the work cycle, and further improving work efficiency;

[0019] 3. A symmetrical and identical first paper tray and a second paper tray are provided. The structure is beautiful and compact. The cost is reduced. The first paper tray is provided at one end close to the positioning frame. The product moves from the first paper tray to the loading assembly, the fixed suction cup, the unloading assembly and the second paper tray in sequence. In addition to the longitudinal movement of the fixed suction cup, the product passes through a U-shaped route. The structure is compact and the layout is set, the footprint is small, the product flow route is the shortest, the work efficiency is improved, and the collection and transportation of the product are also convenient.

[0020] 4. The longitudinal movement of the fixed suction cup is driven by the fourth drive motor and the nut screw structure, the lateral movement of the marking gun is driven by the third drive motor and the nut screw structure, the lateral movement of the first suction cup assembly and the second suction cup assembly is driven by the first drive motor and the nut screw structure, the first suction nozzle is driven by the second drive motor and the nut screw structure, and the loading, unloading, marking lateral movement and longitudinal movement involved in the marking action are all driven by the motor and the nut screw structure. This structure can achieve high-speed operation and ensure accuracy, which is conducive to improving work efficiency;

[0021] 5. The structure of the paper picking component is the same as that of the paper placing component, which reduces the processing cost. The lifting and lowering of the paper picking component is realized by the lifting cylinder, and the movement is realized by the flat plate horizontal cylinder. The process from the first paper placing tray to the loading component is a pre-reserve process, which can be completed during the marking process. Therefore, the time cycle is relatively long. The cylinder structure can meet the production cycle, and the cost is lower and the structure is simpler, which further reduces the cost of the entire structure;

[0022] 6. After the horizontal bracket and the vertical bracket are changed to the fixed position through the long holes, the adsorption area of ​​the first suction nozzle can be changed, which is suitable for the adsorption of products of different specifications. The horizontal plate and the vertical plate can be adjusted to fix their positions to each other through the long holes to meet the needs of adsorption and fixation of products of different specifications.

[0023] 7. The coding is positioned by the CCD visual detection device with high precision. The CCD visual detection device can read the coding content and store it, which is convenient for viewing and editing, and has a high degree of automation;

[0024] 8. After setting up the anti-collision blocks, it is helpful to position the slide at the extreme positions at both ends, thereby ensuring the positioning accuracy of the fixed suction cup. After setting up the anti-collision rubber pads, it has a certain buffering effect on the slide to avoid direct hard contact and cause damage or wear. BRIEF DESCRIPTION OF THE DRAWINGS
