Description

Technical Field

[0001] This invention relates to the field of laser marking technology, and in particular to a novel laser rapid marking device for the bottom lid of milk powder cans. 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. Laser marking can produce various texts, symbols, and patterns, with character sizes ranging from millimeters to micrometers. This is particularly significant for product anti-counterfeiting. The basic principle of laser marking is that a high-energy continuous laser beam is generated by a laser generator. The focused laser acts on the substrate material, causing the surface material to melt or even vaporize instantly. By controlling the path of the laser on the material surface, the desired graphic marking is formed. Laser marking is characterized by non-contact processing, allowing marking on any irregularly shaped surface without deformation or internal stress. It is suitable for marking materials such as metal, plastic, glass, ceramics, wood, and leather. Lasers can mark almost all parts (such as pistons, piston rings, valves, valve seats, hardware tools, sanitary ware, electronic components, etc.), and the markings are wear-resistant. The production process is easily automated, and the marked parts experience minimal deformation. Laser marking machines use a scanning method, where the laser beam is incident on two reflectors. A computer-controlled scanning motor drives the reflectors to rotate along the X and Y axes respectively. After the laser beam is focused, it falls on the workpiece to be marked, thus forming the laser marking mark.

[0003] Existing milk powder manufacturers primarily transport products via assembly lines, printing production dates and other information during the process. Current equipment typically uses single-channel laser marking, resulting in insufficient utilization of the laser machine and limiting the number of markings per unit time. Due to dynamic marking, the printing quality is unstable due to vibrations during transport and wear and tear from long-term use of the conveyor line, leading to customer complaints and ultimately affecting brand image. To address these issues, we propose a novel rapid laser marking device for the bottom lid of milk powder cans. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the technology where milk powder manufacturers primarily transport products via assembly lines, printing information such as production dates during the process. Existing equipment typically uses single-channel laser marking, resulting in insufficient utilization of the laser machine and a limited number of markings per unit time. Furthermore, dynamic marking is susceptible to unstable printing quality due to vibrations during transport and wear and tear from long-term use of the conveyor line, leading to customer complaints and ultimately affecting brand image.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. Place the milk powder can to be marked on the conveyor belt. Activate the second drive to rotate the second connecting shaft, which in turn rotates the power wheel and the transmission belt, conveying the milk powder can. Activate the first sliding lock block to push the first moving plate, which in turn moves the second support rod horizontally. This, in turn, moves the first guide plate horizontally in the opposite direction, allowing the two first guide plates to cooperate and guide the milk powder can placed on the conveyor belt. Activating the second sliding lock block allows adjustment of the working positions of the two second guide plates, facilitating the adjustment of the guiding range. Once the milk powder can moves on the conveyor belt to the anti-error plate, activate the fifth drive to rotate the fourth gear, thereby conveying... The fifth gear rotates, which in turn drives the fifth connecting shaft and the error-proof plate to rotate. The two error-proof plates work together to prevent workers from mistakenly loading large milk powder cans. After passing through the error-proof plate, the milk powder can enters the sorting mechanism, which sorts the sealed milk powder cans into different channels. The dual-channel frequency division mechanism alternately transports the milk powder cans to the laser marking position and keeps them stationary. At the marking position, the milk powder can triggers a sensor, which sends a signal to the control system. The control system sends the marking content to the laser machine, which marks the bottom cover of one channel of milk powder cans. After marking is completed, the laser machine immediately marks the bottom cover of the other channel of milk powder cans, completing the rapid laser marking of the bottom cover of the milk powder cans.

[0018] 2. When the feeding mechanism needs to transport milk powder cans to workbenches of different heights, the limit rod is pulled out to adjust the working height of the second connecting plate, thereby adjusting the working height of the conveyor belt. This facilitates the feeding mechanism to transport milk powder cans to workbenches of different heights. The first driver is turned on to drive the second driver to rotate, which in turn drives the first gear to rotate, and then drives the fourth connecting plate to move vertically. The working height of the power wheel is adjusted, thereby adjusting the feeding height of the conveyor belt. This makes it easier for operators of different heights to use the conveyor belt for feeding, improving the material feeding speed. The fourth driver is turned on to drive the third gear to rotate, which in turn drives the two fourth support plates to move. The installation positions of multiple mounting screws are adjusted to facilitate the fixing of the feeding mechanism and ensure the stability of the feeding mechanism's working state. When it is necessary to move the feeding mechanism, the third driver is turned on to drive the second gear to rotate, which in turn drives the third connecting shaft to rotate, causing the two rollers to rotate and contact the ground, thereby moving the feeding mechanism.

[0019] 3. Error prevention mechanisms are installed sequentially along the conveying direction to prevent workers from loading the wrong workpiece. Further, a feeding guide mechanism is set up to improve the stability of milk powder can feeding. The bottom of the two laser machines and the bottom of the bottom are equipped with continuously rotating turntables, so that the laser machines can mark at random positions on the bottom cover of the milk powder can body. The two laser machines randomly print different fonts to improve the anti-theft marking effect. Attached Figure Description

The sensor and control system includes two laser machines 4 located at the upper and lower ends of the milk powder can body 2, respectively. The feeding mechanism includes a fixed wheel 7 and a drive wheel 8. A conveyor belt 9 is provided between the drive wheel 8 and the fixed wheel 7, and a fixed plate 10 is provided between the drive wheel 8 and the fixed wheel 7. The fixed plate 10 is movably engaged with the feeding guide mechanism, and the error prevention mechanism is also movably engaged with the fixed plate 10. The fixed wheel 7 is connected to a first ground support plate 11 through a first connecting mechanism, and the drive wheel 8 is connected to a second ground support plate 12 through a second connecting mechanism. The first connecting mechanism includes a vertically arranged first connecting plate 13, which is hollow.

The connection mechanism includes a vertically arranged third connecting plate 16, which is hollow. A fourth connecting plate 17 is inserted into the third connecting plate 16, and a first driver 18 is mounted on the fourth connecting plate 17. The output end of the first driver 18 is connected to the power wheel 8. A second driver 19 is mounted on the side wall of the third connecting plate 16, and the output end of the second driver 19 passes through the side wall of the third connecting plate 16 and is connected to a second connecting shaft 20. A first gear 21 is mounted on the second connecting shaft 20, and a first tooth groove meshing with the first gear 21 is mounted on the side wall of the fourth connecting plate 17. A mounting groove 22 is mounted on the first ground support plate 11, and a third driver 23 is mounted on the inner wall of the mounting groove 22.

The opposite side walls of the two second support plates 27 are each connected to rollers 29 through a fourth connecting shaft 28. The milk powder can body 2 to be marked is placed on the conveyor belt 9. The second drive motor 19 is turned on to drive the second connecting shaft 20 to rotate, thereby driving the power wheel 8 to rotate, driving the transmission belt 9 to rotate, and conveying the milk powder can body 2. The first sliding lock block 46 is then opened.Pushing the first moving plate 45 causes the second support rod 44 to move horizontally, which in turn causes the first guide plate 48 to move horizontally in the opposite direction. This allows the two first guide plates 48 to cooperate in guiding the milk powder can body 2, which is placed on the conveyor belt 9, into the feed. Opening the second sliding lock block 51 allows adjustment of the working positions of the two second guide plates 49, facilitating adjustment of the guiding range. The milk powder can body 2 moves on the conveyor belt 9 to the anti-error plate 42.

The system uses a barrier to prevent workers from mistakenly loading larger milk powder cans. After passing through an anti-mistake plate 42, the cans enter a separating mechanism 1, which divides the sealed cans into two channels. A dual-channel frequency-dividing mechanism 3 alternately transports the cans to the marking position on the laser machine 4, where they remain stationary. At the marking position, a sensor on the can 2 is triggered, sending a signal to the control system. The control system then sends the marking information to the laser machine 4. The laser machine 4 marks the bottom cover of one can, and immediately after marking, it marks the bottom cover of the other can, completing the rapid laser marking of the can bottoms.

The first driver 18 is activated, driving the second driver 19 to rotate, which in turn drives the first gear 21 to rotate, thereby causing the fourth connecting plate 17 to move vertically. This adjusts the working height of the power wheel 8, thereby adjusting the loading height of the conveyor belt 9, thus facilitating the transport of milk powder cans to workbenches 6 of different heights. The operator uses the conveyor belt 9 to feed materials, increasing the feeding speed. Activating the fourth drive 34 rotates the third gear 35, which in turn moves the two fourth support plates 33. This allows for adjustment of the mounting positions of multiple mounting screws 31, facilitating the fixing of the feeding mechanism 5 and ensuring its stable operation. When the feeding mechanism 5 needs to be moved, the third drive 23 rotates the second gear 24, which in turn rotates the third connecting shaft 26, causing the two rollers 29 to rotate and contact the ground, thus moving the feeding mechanism 5.

After passing through the error-proof plate 42, the milk powder can body 2 enters the channeling mechanism 1, which divides the sealed milk powder cans into two channels and enters the equipment. The dual-channel frequency division mechanism 3 alternately transports the milk powder cans to the marking position of the laser machine 4 and keeps them stationary. At the marking position, the milk powder can body 2 triggers the sensor, which sends the signal to the control system. The control system sends the marking content to the laser machine 4.

After the marking is completed, the laser machine 4 immediately marks the bottom cover of the milk powder can in the other channel, completing the rapid laser marking of the bottom cover of the milk powder can.

[0034] When the feeding mechanism 5 needs to transport milk powder cans to workbenches 6 of different heights, the limit rod 57 is pulled out to adjust the working height of the second connecting plate 14, thereby adjusting the working height of the conveyor belt 9. This facilitates the feeding mechanism 5 to transport milk powder cans to workbenches 6 of different heights. The first driver 18 is activated, driving the second driver 19 to rotate, which in turn drives the first gear 21 to rotate, thereby causing the fourth connecting plate 17 to move vertically. This adjusts the working height of the power wheel 8, thereby adjusting the loading height of the conveyor belt 9, thus facilitating the transport of milk powder cans to workbenches 6 of different heights. The operator uses the conveyor belt 9 to feed materials, increasing the material feeding speed. The fourth drive 34 is turned on to drive the third gear 35 to rotate, which in turn drives the two fourth support plates 33 to move. The installation positions of the multiple mounting screws 31 are adjusted to facilitate the fixing of the feeding mechanism 5 and ensure the stability of the feeding mechanism 5. When it is necessary to move the feeding mechanism 5, the third drive 23 is turned on to drive the second gear 24 to rotate, which in turn drives the third connecting shaft 26 to rotate, which drives the two rollers 29 to rotate, so that the two rollers 29 contact the ground, thereby moving the feeding mechanism 5.
