Figure 3As shown, in this embodiment, four sets of laser coding components 3 are provided, and two sets of laser coding components 3 are arranged in pairs. The two sets of laser coding components 3 are respectively aligned with the two belt conveyor mechanisms of the feeding channel 2. Each set of laser coding components 3 includes laser coding component 3A and laser coding component 3B.

[0044] Limit plates are installed on both sides of the belt conveyor to prevent bottle caps from falling during the conveying process, while the two ends of the belt conveyor are used to connect to other equipment.

[0045] In the above technical solution, the laser coding component 3 is set into four sets, with two sets in each group, and is respectively aligned with the two belt conveyor mechanisms of the feeding channel 2. It can simultaneously code the materials in the two channels, which greatly improves the coding efficiency. Each set of laser coding components 3 includes two components, A and B. This grouping setting can independently control the coding of materials in different channels, ensuring the accuracy and consistency of coding.

[0046] like Figures 3-4 As shown, in this embodiment, the two belt conveyor sidewalls in the feeding channel 2 are equipped with counting sensors 4. Both counting sensors 4 are located upstream of the laser coding component 3. The counting sensors 4 are installed on the two sidewalls of the pneumatic feeding channel 2 and are located upstream of the laser coding component 3. This allows the material entering the coding area to be counted in advance, providing accurate quantity information for the coding operation.

[0048] All of the aforementioned optical or electronic components are commercially available and mature products, so their details will not be elaborated upon in this article.

[0049] This QR code coding device achieves efficient automatic coding within a limited space by setting up a feeding channel 2 and a vertically aligned laser coding component 3 within the hollow cavity 12 of the cabinet 1. The laser coding component 3 is adjustable to adapt to changes in the focal point position required for different process effects, ensuring laser focusing. The overall structure of the device is compact, and the layout of each component is reasonable, making it suitable for use in small spaces.

[0050] The specific working principle is as follows: when the bottle cap enters the feeding channel 2, the bottle cap is transported through the feeding channel 2, the bottle cap passes through the counting sensor 4, the counting sensor 4 counts the passing bottle cap, the odd number of bottle caps are coded by the laser coding assembly 3A on the same channel, and the even number of bottle caps are coded by the laser coding assembly 3B, so as to speed up the coding efficiency, by adjusting the rotation of the adjusting rod 35, the worm 36 is engaged with the worm gear 38 on the vertical rod 37, the top plate 39 is driven to ascend and descend, so as to adjust the height of the coder 34, and the coding requirement of different heights is realized. When coding, the laser 341 is vertically assembled and the output end is vertically upward, the reflecting mirror in the light folding piece 343 reflects the laser to the horizontal direction at a 90° reflection angle, and then the laser is accurately focused on the coding position on the feeding channel 2 through the cooperation of the galvanometer 345 and the lens 346, so as to ensure the definition and accuracy of coding.
