Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, specifically to a visual positioning laser marking device. Background Technology

[0002] Laser marking technology is one of the largest applications of laser processing. Laser marking is a marking method that uses a high-energy-density laser to locally irradiate a workpiece, causing the surface material to vaporize or undergo a chemical reaction that changes color, thereby leaving a permanent mark.

[0003] Chinese Patent No. CN221247350U discloses a visual positioning marking device. Its technical solution includes a laser marking machine body and a fan. A hydraulic cylinder is fixedly installed on one side of the upper surface of the laser marking machine body. A lifting frame is fixedly connected to the end of the output shaft of the hydraulic cylinder. A transverse slide is fixedly installed on the top of the inner wall of the lifting frame. A longitudinal slide is fixedly installed at the sliding end of the transverse slide. A fixed plate is fixedly installed at the sliding end of the longitudinal slide. A transparent protective cover, a visual positioning camera, and a laser marking head are fixedly installed on the lower surface of the fixed plate. A smoke filter is fixedly installed at the output end of the fan. This invention can absorb and filter the smoke generated during laser marking, preventing impurities from adhering to the surface of the visual positioning camera lens, improving visual positioning accuracy, and thus improving marking accuracy. Simultaneously, it can blow away dust and impurities at the marking position on the workpiece surface before marking, further improving marking accuracy.

[0004] However, in the above technical solution, gas is blown into the exhaust duct by a fan, and the gas is blown onto the object to be marked on the fixed fixture to remove the dust on its surface. However, when the device is used, it can only remove some lightly attached dust when the gas blows away the dust on the object surface. For some oily dust and dust attracted by static electricity, it is difficult to remove them when the air force is small, and when the air force is large, it will cause displacement and shaking, resulting in errors during laser marking.

The fixed plate 19 has an accommodating cavity. The lifting plate 20 is slidably connected in the accommodating cavity. The handle is connected to the lifting plate 20.

[0024] The cleaning assembly is connected to the workbench 2. The cleaning assembly includes a first telescopic device 4 and a scraping assembly. Two first telescopic devices 4 are provided, each connected to the workbench 2. The scraping assembly is located on the telescopic end of the first telescopic device 4 and includes a second telescopic device 5, a lifting block 6, a moving plate 7, and a cleaning plate 8. The second telescopic device 5 is positioned above the belt conveyor 3, and its telescopic end is connected to the lifting block 6. Two symmetrically arranged moving plates 7 are located on either side of the lifting block 6. The cleaning plate 8 is connected to the moving plate 7, and the moving plate 7 has an inclined surface that cooperates with the lifting block 6. When the cleaning assembly is in use, the telescopic end of the first telescopic device 4 moves up and down, causing the scraping assembly to approach the item. The telescopic end of the second telescopic device 5 moves the lifting block 6, pushing the moving plate 7 and the cleaning plate 8 horizontally to clean the item's surface. A protective assembly is connected to the workbench 2. When the protective assembly is in use, its protective end unfolds to increase its surface area and reduce laser light reflection.

[0025] Example 2

[0026] like Figures 2-4 As shown, the present invention proposes a visual positioning laser marking device. Compared with Embodiment 1, this embodiment describes the detailed structure of the cleaning component. The cleaning component also includes a support plate 9, which is connected to the telescopic end of the first telescopic device 4. The support plate 9 is connected to the second telescopic device 5, and a through hole is provided on the support plate 9 for the telescopic end of the second telescopic device 5 to pass through.

[0027] The scraping assembly also includes a support frame 10 and a reset assembly, the support frame 10 being connected to the support plate 9;

[0028] In an optional embodiment, the support frame 10 consists of a mounting plate 11 and a connecting plate 12. The mounting plate 11 is connected to the telescopic end of the second telescopic device 5, and two symmetrically arranged connecting plates 12 are connected to the side of the mounting plate 11 away from the second telescopic device 5.

[0029] The reset component is connected to the support frame 10; when the reset component is in use, the moving end of the reset component moves horizontally, pushing the moving plate 7 to move synchronously towards each other.

[0030] The reset assembly includes a guide rod 13, a positioning block 14, and an elastic element 15. There are two guide rods symmetrically arranged. The guide rods 13 are slidably connected to the connecting plate 12. One end of the guide rod 13 is connected to the moving block, and the other end of the guide rod 13 is connected to the positioning block 14. The number of elastic elements 15 corresponds to the number of guide rods 13. The elastic elements 15 are sleeved on the outside of the guide rods 13 and are located between the connecting plate 12 and the moving block. The elastic elements 15 are selected from, but are not limited to, springs.

[0031] In summary, when using this utility model, after the operator sets the text to be laser-marked on the computer on the main body 1 of the laser marking machine, the belt conveyor 3 is started to transport the item to be marked. The item moves from upstream to downstream. When it approaches the cleaning component, the belt conveyor 3 will pause. The first telescopic device 4 is activated to drive the support plate 9 down, which in turn moves the support frame 10 closer to the item to be marked. The cleaning plate 8 is pressed tightly against the surface of the item to be marked. After the telescopic end of the second telescopic device 5 extends, it will drive the lifting block 6 to move. The lifting block 6 contacts the inclined surface on the moving plate 7 through the inclined surfaces on its two sides. The lifting block 6 pushes the moving plate 7 to compress the length of the elastic element 15 and drives the guide rod 13 and the positioning block 14 to move horizontally. The moving plate 7 moves horizontally closer to the edge of the moving plate. The distance between the connecting plate 12, the moving plate 7, and the cleaning plate 8 gradually increases, and the moving plate scrapes the surface of the item to be printed to clean it. After the cleaning action is completed, the first telescopic device 4 and the second telescopic device 5 are reset, and the elastic element 15 rebounds to push the moving plate 7 back to its original position. Then the belt conveyor 3 starts to continue to transport the item to be printed. The item to be printed gradually enters the area below the laser scanning galvanometer of the laser marking machine body 1 for marking. The operator can pull the handle to rotate the protective baffle 17 so that one end of the protective baffle 17 enters the limiting groove on the limiting base 18 to block the laser and the item. At the same time, the operator can also pull the handle to pull out the extension plate 20 to increase the blocking range of the protective baffle 17.
