Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser marking device technology, and in particular to a non-destructive laser marking online marking device. Background Technology
[0002] Non-destructive laser marking online marking devices are an advanced marking technology that plays a vital role in modern industrial production. This device combines the principle of laser-matter interaction, using a laser beam to burn and etch patterns or text onto the surface of an object, vaporizing the surface material. During this process, the effective displacement of the laser beam is precisely controlled to ensure high precision and high quality marking.
[0003] Non-destructive laser marking online marking devices are mainly divided into several types, such as CO2 laser marking machines, fiber laser marking machines, and ultraviolet laser marking machines. These different types of laser marking machines each have their advantages and are suitable for different materials and marking needs. For example, CO2 laser marking machines perform excellently on non-metallic materials, while fiber laser marking machines excel at marking on metal surfaces. Ultraviolet laser marking machines have the special ability to create invisible marks on transparent material surfaces; these invisible marks only appear under specific conditions, providing both aesthetic appeal and a certain degree of anti-counterfeiting functionality.
[0004] An existing non-destructive laser marking online inkjet printer, in conjunction with a conveyor belt, rapidly laser-marks items to be marked. However, in actual production, these marked items may be conveyed from conveyor belts of other processing lines. Since the items themselves have a certain inertial speed, their landing point cannot be accurately controlled when they reach the conveyor belt where the marking device is located. This results in some items failing to be marked successfully when passing the marking nozzle. The current solution involves adding manual labor between the two conveyor belts, with workers placing the items destined for the next production line in the middle of the conveyor belt. This requires workers to be constantly present at the machine; for a machine operating 24 hours a day, at least three workers are needed to take turns monitoring it, resulting in significant labor costs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-6 A non-destructive laser marking online inkjet printing device includes a mounting frame 1, on which a conveying mechanism is provided. A connecting frame 2 is fixedly installed on the side wall of the mounting frame 1, and a laser marking nozzle 3 is fixedly installed on the connecting frame 2. The laser marking nozzle 3 is positioned directly above the conveying mechanism. Two support frames 4 are fixedly installed at the top of one end of the mounting frame 1, and a support plate 5 is provided on the top of the two support frames 4. Pushing plates 6 are slidably arranged on both sides of the support plate 5. When using this device to laser mark the surface of an item, in order to prevent the item from moving to the edge of the next conveyor belt 9 due to its original inertia, which would be detrimental to the laser marking nozzle 3 marking at the designated position, the support plate 5 is used to support the item, and the two pushing plates 6 push the item to the center of the support plate 5 before it reaches the next conveyor belt 9, facilitating the precise positioning of the laser marking nozzle 3.
[0025] As a preferred embodiment, the conveying mechanism includes two drive shafts 7, which are rotatably mounted at both ends of the mounting frame 1. Conveying rollers 8 are fixedly mounted on the outer side walls of the two drive shafts 7, and conveyor belts 9 are sleeved on the two conveying rollers 8. A motor 10 is fixedly mounted on the side wall of the mounting frame 1, and the output end of the motor 10 passes through the side wall of the mounting frame 1 and is fixedly connected to one of the drive shafts 7. The motor 10 drives the drive shafts 7 to rotate, which in turn drives the conveying rollers 8 to rotate, causing the conveyor belt 9 to move and convey the items that arrive on the conveyor belt 9 to the bottom of the laser marking nozzle 3.
[0026] As a preferred technical solution in this embodiment, a support rod 11 is fixedly connected between the support frame 4 and the supporting railing 5; the supporting rod 11 supports the supporting railing 5.
[0027] As a preferred embodiment, mounting plates 12 are fixedly installed on the tops of both support frames 4, and two push plates 6 are disposed on the tops of the mounting plates 12. A sliding assembly is provided between the mounting plates 12 and the push plates 6. A support column 13 is rotatably connected to the top of the mounting plates 12, and a connecting rod 14 is fixedly installed at the top of the support column 13. A transmission rod 15 is rotatably connected to the two ends of the connecting rod 14 that are far apart from each other. The ends of the two transmission rods 15 that are far away from the connecting rod 14 are respectively rotatably connected to the bottoms of the two push plates 6. Two cylinders 16 are fixedly installed on both sides of the top of the mounting plate 12, and the output ends of the two cylinders 16 are fixedly connected to the bottom of one of the push plates 6. During the use of this device, the cylinders 16 push one of the push plates 6 to move, causing the transmission rod 15 connected to it to drive one end of the connecting rod 14 to rotate around the support column 13, so that the connecting rod 14 drives the other end of the transmission rod 15 to move, thereby driving the other push plate 6 to move accordingly. The push plates 6 can slide based on the sliding assembly limiting the sliding of the two push plates 6.
[0028] As a preferred technical solution of this embodiment, the sliding component includes two slide rails 17, which are fixedly installed on the top two sides of the mounting plate 12. Slider 18s are fixedly installed on the bottom two sides of the two push plates 6 respectively. The two sliders 18 at the bottom of the same push plate 6 are slidably engaged with one end of the two slide rails 17 respectively. Through the sliders 18 and the slide rails 17, the push plate 6 can slide while the push plate 6 is limited in its sliding position.
[0029] As a preferred embodiment, the bottom end of the support column 13 is fixedly connected to the mounting plate 12 via a first gear 19. A second gear 20 is disposed on the first gear 19. The second gear 20 is rotatably mounted on the bottom of the mounting plate 12. A turntable 21 is fixedly mounted on the second gear 20. A crank 22 is rotatably mounted on one side of the bottom of the turntable 21. A push rod 23 is rotatably connected to one end of the crank 22. A connecting plate 24 is fixedly mounted on the end of the push rod 23 away from the crank 22. A top rod 25 is fixedly mounted on the end of the connecting plate 24 away from the push rod 23. A limit plate 26 is fixedly mounted on the side wall of the mounting plate 12. The push rod 23 and the... The top rod 25 is slidably connected to both ends of the limiting plate 26. While the support column 13 rotates, the first gear 19 rotates, driving the second gear 20 to rotate, causing the turntable 21 to rotate. This, in turn, causes the position of the crank 22 connected to the turntable 21 to change continuously, thereby pushing the push rod 23 to move. When the two push plates 6 push the item towards the center of the support plate 5, the top rod 25 retracts under the action of the turntable 21, the push rod 23, and the crank 22. When the item reaches the center position, the two push plates 6 move away from each other, causing the support column 13 to reverse, so that the top rod 25 returns to its original position, pushing the item down from the support plate 5 to the top of the conveyor belt 9. The limiting plate 26 slides and limits the push rod 23 and the top rod 25.
