Technical Field

[0001] This utility model relates to the field of coating laser engraving technology, specifically to a laser engraving device for coating heart rate monitoring lenses. Background Technology

[0002] Laser engraving of coatings is a very mature and widely used technology in modern industry, especially in the fields of electronics, optics, automobiles, and decoration. By using a laser beam to locally remove or change the coating, functions such as fine patterns, conductive paths, and translucent markings can be achieved. It has significant advantages such as high precision, non-contact operation, no consumables, and automation.

[0003] When performing laser engraving on the coating of heart rate monitoring lenses on an automated production line, the engraving is mainly done using a pre-programmed laser program. The engraving speed is very fast. However, if product quality is not monitored, defective products can easily be mixed in and enter the next processing step. Furthermore, independent inspection after engraving would greatly increase production costs and reduce work efficiency. Therefore, it is necessary to design a laser engraving device with an automatic detection structure. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: including a processing table (1), characterized in that: a rotating disk (2) is rotatably connected to the processing table (1), and loading slots (21) are equidistantly provided on the rotating disk (2), a groove is provided at the middle position of the bottom of the loading slot (21), and a backlight (22) is installed at the bottom of the groove; a pair of equipment racks (3) are fixed at the upper end of the processing table (1) and behind the rotating disk (2), and a laser engraving machine (31) and an industrial camera (32) are respectively fixed on the equipment racks (3), and adjacent loading slots (21) are connected in a certain way. Aligned, the processing table (1) is equipped with a feeding conveyor belt (4) and a finished product conveyor belt (5) on both sides. A positioning sensor (41) is fixed at the feeding area outside the feeding conveyor belt (4). A scrap table (6) is fixed at the upper end of the processing table (1) near the finished product conveyor belt (5). A robotic arm (9) is installed between the feeding conveyor belt (4), the finished product conveyor belt (5), the scrap table (6) and the rotating disk (2). A stepper motor that drives the rotating disk (2) to rotate is fixed inside the processing table (1). A controller is fixed at the upper end of the processing table (1).

[0019] The robotic arm (9) consists of a rotating base (91), a telescopic cylinder (92), a horizontal plate (93), and a vacuum suction cup (94). The rotating base (91) is rotatably connected to the upper end of the processing table (1). The telescopic cylinder (92) is fixed to the upper end of the rotating base (91). The horizontal plate (93) is fixed to the output end of the telescopic cylinder (92). The bottom of the horizontal plate (93) of the vacuum suction cup (94) is away from the side of the telescopic cylinder (92). A servo motor that drives the rotating base (91) to rotate is fixed inside the processing table (1).

[0021] Working Principle: First, the entire device is connected to an external power source. After the feeding conveyor belt carries the semi-finished lenses to the feeding area, the robotic arm 9 automatically feeds the lenses using a vacuum suction cup 94. After feeding, the rotating disc 2 allows the lenses to pass sequentially under the laser engraving machine 31 and the industrial camera 32, finally reaching the unloading area. The robotic arm 9 then unloads the lenses. The laser engraving machine 31 engraves on the coating surface, and the industrial camera 32 captures images, achieving visual inspection. During visual inspection, the backlight 22 makes the engraving marks clearer, leading to more accurate visual inspection. Based on the inspection results, the second robotic arm 9 transfers the lenses to the finished product conveyor belt 5 or the waste table 6 for stacking. The column 7 ensures stable stacking of the lenses on the waste table 6. After stacking to a specified height, the height sensor 81 detects the stacking and allows for timely batch retrieval. The entire process achieves automatic inspection of the engraved lenses, improving work efficiency.
