Description

Technical Field

[0001] This application relates to the field of automated equipment, and in particular to a positioning mechanism and a laser marking device. Background Technology

[0002] Laser marking technology is one of the largest applications of laser processing. Laser marking uses a high-energy-density laser to locally irradiate materials, causing the surface material to vaporize or undergo a chemical reaction that changes color, thus leaving a permanent mark. Laser marking can produce various texts, symbols, and patterns, with character sizes ranging from millimeters to micrometers, which is particularly significant for anti-counterfeiting purposes. Existing laser marking equipment requires an additional conveying mechanism to transport the material to the marking head during the marking process, making its structure relatively complex.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0046] This application proposes a positioning mechanism, referring to... Figures 1 to 5 The system includes: a chute 21, inclined in arrangement; a first baffle 221, disposed on the chute 21, used to prevent material from sliding within the chute 21; a first drive 222, used to drive the first baffle into the chute 21; and a suction hole 233, located above the first baffle 221, for adsorbing material. When material enters from the upper end of the chute 21, it slides down to the first baffle 221 under gravity and is blocked by the first baffle 221. The material is then adsorbed by the suction hole 233, thus fixing it in place. After marking, the first drive 222 drives the first baffle 221 away from the chute 21 to release the material, which can then slide down the chute 21 to the next station without the need for additional conveying facilities.

[0047] In this embodiment, material is fed into the chute 21 via vibration feeding or other methods. The material enters the chute 21, is blocked by the first baffle 221, and is then adsorbed and fixed by the suction port 233, where it is marked by the marking head 31. After marking is complete, the suction port 233 stops suction, and the first baffle 221, driven by the first drive member 222, moves away from the chute 21, releasing the material. The material can then slide down the chute 21 to the next station without the need for additional conveying facilities. It is worth noting that the section of the chute 21 located above the first baffle 221 refers to the section located diagonally above the first baffle 221 in the extending direction of the chute 21.

[0048] In some embodiments, the section of the chute 21 with suction holes 233 includes a first section and a second section arranged sequentially, with the second section located above the first section. The chute 21 also has a first air passage 231 communicating with the suction holes 233 in the first section and a second air passage 232 communicating with the suction holes 233 in the second section. In this embodiment, the suction holes 233 can be located on the bottom wall or side wall of the chute 21, and two negative pressure air passages can also be provided inside the chute 21. When multiple materials accumulate inside the chute 21 and exceed the range of the first section, the first baffle 221 releases the materials, and the first air passage 231 stops suction, allowing a set number of materials to flow to the next station. The second air passage 232 continues suction to prevent unprocessed materials in the chute 21 from sliding down. When the first baffle 221 returns to the chute 21 and stops the material, the second air passage 232 stops sucking air, and the remaining material in the chute 21 slides into the first section. The first air passage 231 and the second air passage 232 can also suck air at the same time to re-fix the material entering the first section for subsequent marking operations.

[0049] In some embodiments, the positioning mechanism 2 further includes a first cover plate 241 disposed on one side of the first section, and a second driving member 142 for pushing the first cover plate 241 toward the first section. In this embodiment, the depth of the chute 21 can be set to be less than twice the thickness of the material. When the first cover plate 241 is driven by the second driving member 242 and covers the chute 21, it can block the opening of the first section of the chute 21, making the chute depth less than twice the thickness of the material, so that the material entering the first drive will not accumulate in the thickness direction. If accumulation occurs, in the depth direction of the chute 21 or the thickness direction of the material, the material on the upper side may be outside the focal point, and the marking content will be very blurry. At the same time, the material on the lower side will be missed in marking due to the obstruction of the material on the upper side. The arrangement of the first cover plate 241 and the second driving member 242 can avoid the situation where some material is missed in marking and some material is marked blurry due to material accumulation. The first cover plate 241 can also be inclined along the chute 21, and the moving direction is along the width direction of the chute 21. Of course, during the marking process, the first cover plate 241 should still be kept away from the slot to avoid the laser beam and prevent it from blocking the laser beam used for marking.

[0050] In some embodiments, the positioning mechanism 2 includes a base plate 211 and a mounting plate 213. A protrusion 212 is provided on one edge of the base plate 211. The mounting plate 213 is disposed on the base plate 211 and spaced apart from the protrusion 212. A groove 21 is formed between the protrusion 212 and the mounting plate 213. An elongated hole is provided on the mounting plate 213 for adjusting the distance between it and the protrusion 212. In this embodiment, the elongated hole extends along the width direction of the groove 21. A screw hole corresponding to the elongated hole can be provided on the base plate 211, and a screw penetrating the elongated hole can be screwed into the screw hole. The width of the groove 21 can be adjusted by loosening the screw. After the adjustment is completed, the screw can be tightened, thereby adapting to materials of different widths.

[0051] This application also proposes a laser marking device, referring to... Figures 1 to 8 The system includes the aforementioned positioning mechanism 2, a feeding mechanism 1 including a feeding trough 13, and a marking mechanism 3 including a marking head 31 positioned above the chute 21 and a driving assembly for moving the marking head 31. Material enters the chute 21, is blocked by the first stop 221, and is adsorbed and fixed by the suction hole 233. Marking is then performed by the marking head 31. Afterward, the suction hole 233 stops suction, and the first stop 221 moves away from the chute 21 to release the material. The material can slide down the chute 21 to the next station without additional conveying facilities. For materials of different thicknesses, the driving assembly can be used to move the marking head 31 for focusing.

[0052] In some embodiments, the laser marking equipment further includes: a first sensor 251, disposed in a first section, for detecting material; a second stop 261, disposed at one end of the chute 21 that connects with the feeding trough 13; a third drive 262, for driving the second stop 261 into the chute 21; and a second sensor 252, disposed at one end of the chute 21 that connects with the feeding trough 13, for detecting material. In this embodiment, the second stop 261 is used to control the material entering the chute 21, and the first sensor 251 and the second sensor 252 can be used to detect the quantity of material. N first sensors 251 can be set, and the first sensors 251 are evenly arranged along the length direction of the chute 21, with each first sensor 251 corresponding to one material. When the first stop 221 is in the stopping state, the second stop 261 at the upper end of the chute 21 is in the discharging state. Each time a piece of material is discharged, the second sensor 252 generates a signal change. After N pieces of material have been discharged, the second stop 261, driven by the third drive 262, enters the chute 21 and prevents further material from entering, allowing the feeding trough 13 to stop feeding. When each first sensor 251 detects corresponding material, the suction port 233 can absorb and fix the material, and the marking mechanism 3 performs marking. After marking, the first stop 221 releases the material. As the marked material leaves the first section, the first stop 221 returns to its original position and enters the chute 21 to begin the next round of stopping. Then, the second stop 261 releases the material again, completing the next round of feeding and marking. It is worth noting that N can be 1, 2, or an integer greater than 2. The size of N is determined by the number of marks that the marking head 31 can make at one time. The material in the first section needs to be within the effective marking field of the marking head 31. Of course, multiple chutes 21 can be arranged side by side. Multiple chutes 21 can share a first stop 221 and a first drive 222, which can intercept multiple rows of material at one time and mark multiple rows of material, further improving the marking efficiency.

[0053] In some embodiments, the marking mechanism 3 includes: a vision camera 32, disposed above the slide 21 with its optical axis facing the inner bottom surface of the slide 21; a lens assembly, including a field lens with its optical axis parallel to the slide 21; and a reflective mirror 37, disposed at the intersection of the optical axis of the vision camera 32 and the optical axis of the field lens. The reflective mirror 37 and the lens assembly constitute the marking head 31. In this embodiment, by reasonably arranging the positions of the vision camera 32 and the lens assembly, and by adding the reflective mirror 37, the vision camera 32 and the lens assembly can be kept coaxial. Furthermore, the vision camera 32 can be used for visual positioning of materials and for quality inspection after marking.

[0054] Furthermore, the laser marking equipment also includes a bracket 33 for mounting the vision camera 32, lens assembly, and reflector 37. The bracket 33 is connected to the drive assembly. In this embodiment, the drive assembly includes a first electric cylinder 34 arranged horizontally and a second electric cylinder 35 located at the drive end of the first electric cylinder 34. The bracket 33 is located at the drive end of the second electric cylinder 35. The second electric cylinder 35 constitutes a servo Z-axis, and the first electric cylinder 34 constitutes a servo X-axis. Both act to adjust the laser focal length and the focal length of the vision camera 32. The vision camera 32 and lens assembly can be raised and lowered to a specified focal length position according to the size of each material, waiting for the instruction to take pictures and position for marking. The vision camera 32 is mounted on the bracket 33, which can eliminate the slight shaking of the vision camera 32, thereby improving the positioning accuracy. A ring light source 36 is also provided on the lower side of the reflector 37, which can be used for illumination compensation when positioning the vision camera 32.

[0055] In some embodiments, the feeding mechanism 1 further includes: a mounting frame 15; a shock absorber mounted on the mounting frame 15; a linear feeder 14 mounted on the shock absorber and connected to the feeding trough 13; and a disc feeder 12 mounted on the shock absorber and connected to the feeding trough 13. In this embodiment, the disc feeder 12 and the linear feeder 14 are used for vibratory feeding, which can feed materials into the storage bin 11. A vibrator can be installed on the storage bin 11, which can periodically feed materials into the disc feeder 12. The disc feeder 12 then arranges the materials sequentially according to the material parameters set by the system, and uniformly faces the marking surface, and conveys them to the feeding trough 13 on the linear feeder 14. The linear feeder 14 then feeds the materials into the chute 21. The shock absorber includes multiple stacked and spaced shock-absorbing blocks 16, which mainly reduce the vibration generated by the disc feeder 12 and the linear feeder 14.

[0056] Furthermore, the laser marking equipment also includes a frame, which has an installation space for accommodating the mounting bracket 15. The mounting bracket 15 is spaced apart from the frame, and the positioning mechanism 2 and the marking mechanism 3 are mounted on the frame. In this embodiment, the mounting bracket 15 is separately mounted from the frame and independently contacts the ground, completely eliminating the influence of the feeding mechanism 1 on the marking mechanism 3. The mounting bracket 15 can be a frame structure constructed of tubular materials, with connecting blocks and reinforcing ribs on its sides, allowing for quick disassembly of the mounting bracket 15. The mounting bracket 15 is located inside the frame, reducing material transport distance and improving marking accuracy.

[0057] In some embodiments, the laser marking equipment further includes a connecting groove 271 connecting the chute 21 and the feeding trough 13, the connecting groove 271 being arc-shaped; the laser marking equipment also includes an air blowing component and a dust suction component disposed on one side of the chute 21. In this embodiment, the chute 21 can be inclined at 45°, specifically disposed on a mounting base. The material can quickly slide into the first section by its own gravity. The feeding trough 13 can be horizontally disposed, and the chute 21 can be inclined. For a smooth transition between the two, an arc-shaped connecting groove 271 can be provided. When the connecting groove 271 is full, the third driving component 262 operates to cause the second material stop component 261 to block the material from pushing forward. The material in the chute 21 moves to the first section to wait for the marking instruction. The dust extraction port removes the dust generated during marking. After marking is completed, the material slides into the receiving container 41.

[0058] In some embodiments, a second cover plate 272 may be provided on the connecting groove 271, which, together with the first cover plate 241, can adjust the groove depth according to the size of the material. When the second sensor 252 senses that the material has been stationary for a period of time, it will transmit a working signal to the third drive member 262 to prevent the material from being pushed forward. The second cover plate 272 and the first cover plate 241 can prevent the material from sliding down and leaving the chute 21. The first sensor 251 and the second sensor 252 may be optical fibers. When the material has not slid down to the first sensor 251 at the marking position (first section), the first drive member 222 pushes the first stop member 221 to extend and block the material at the marking position. At the same time, the second drive member 242 pushes the first cover plate 241 to extend and prevent the material from stacking and being squeezed.

[0059] When the material slides to the marking position (first section), the optical fiber sensor at the marking position detects that the first four materials have arrived. The second drive unit 242 pulls the first cover plate 241 back to create marking space, while simultaneously adsorbing the material onto the suction port 233. The signal is then fed back to the vision camera 32 and the marking mechanism 3 to start taking pictures and marking the four materials. The dust blowing nozzle 253 blows the dust generated during marking into the dust extraction port to quickly remove the dust. When marking is complete, the first drive unit 222 pulls the first stop 221 back, the suction port 233 stops sucking air and releases the material, and the material rejection nozzle 254 blows air to remove the first four processed materials, preventing the material from sticking to the chute 21. The above process is repeated to achieve rapid batch marking of materials.

[0060] In some embodiments, the laser marking equipment further includes a receiving container 41 located at one end of the slide 21. The receiving container 41 can be filled with water. Some materials are made of brittle materials, such as ceramics and glass, and have very high requirements for impact resistance. The water cushions the falling materials, preventing them from colliding with each other. The receiving container 41 can be housed in a drawer 42. The inner wall of the drawer 42 is also waterproofed and can be used in water. The drawer 42 is slidably connected to the frame via a slide rail 43 and can be housed inside the frame. The drawer 42 completely isolates splashed water droplets from other electronic equipment inside the frame. The slide rail 43 is a heavy-duty slide rail, ensuring smooth extension and retraction. It is worth noting that the material in this embodiment can be a ceramic dielectric filter, but it is not limited to filters.

[0061] The key technical aspects of the laser marking equipment in this embodiment are as follows:

[0062] Key point 1: By tilting the entire fixture at a 45° angle, the vision and laser marking modules are also tilted at a 45° angle to form a perpendicular angle with the fixture plane, so that the material can be pushed forward by its own gravity and can automatically and quickly slide down without any power.

[0063] Key point 2: The internal space of the equipment is narrow, and the feeding mechanism 1 needs to be set separately from the frame to eliminate the influence of vibration on the laser. The installation position needs to be reserved in advance, and the vibration source is completely isolated from the marking mechanism 3 to ensure the high precision of the material.

[0064] Key point 3: The material size and width are very small, which places very high demands on the clamping device during processing. In addition, space is limited. By adopting two-way vacuum suction path to control the start, stop and rejection of materials, the complex mechanism layout is solved and the processing efficiency is improved.

[0065] Key Point 4: There are focal length requirements for vision and laser marking. The surface height of each material is different. It is necessary to use the height difference of each material and the angle of the slide 21 to calculate the optimal focal length for each material, and the drive component will complete the focusing.

[0066] In this embodiment, the working principle of the positioning mechanism and the laser marking equipment is as follows: The laser marking equipment includes a feeding mechanism 1, a positioning mechanism 2, and a marking mechanism 3. The feeding mechanism 1 includes a feeding groove 13; the positioning mechanism 2 includes a slide 21 that docks with the feeding groove 13, a first baffle 221 disposed on the slide 21, and a first driving member 222 that drives the first baffle into the slide 21. The end of the slide 21 away from the feeding groove 13 is obliquely downward. The section of the slide 21 located above the baffle is also provided with a suction hole 233, which is used to adsorb materials; the marking mechanism 3 includes a marking head 31 disposed above the slide 21 and a driving assembly. The material enters the chute 21, is blocked by the first baffle 221, and is adsorbed and fixed by the suction hole 233. The marking head 31 marks the material. Then the suction hole 233 stops sucking air, the first baffle 221 moves away from the chute 21 to release the material, and the material can slide down the chute 21 to the next station without the need for additional conveying facilities. For materials of different thicknesses, the marking head 31 can be moved by the drive component to adjust the focus.
