Description

Technical Field

[0001] This utility model relates to the technical field of laser engraving equipment, and in particular to a metal ring laser engraving machine. Background Technology

[0002] A laser engraving machine is a device that uses a laser beam to carve permanent marks on the surface of a material or inside a transparent material. The principle is that when a material instantly absorbs the laser light, a physical or chemical reaction occurs, thereby engraving marks, patterns, or text. In the field of metal ring processing, laser engraving machines are widely used to engrave logos, patterns, and other designs on the surface of metal rings.

[0003] However, existing metal ring laser engraving machines have some problems in practical use. On the one hand, the lack of convenient and efficient positioning and fixing devices for metal rings of different sizes and specifications makes it easy for the metal rings to shift during laser engraving, affecting the accuracy and quality of the engraving. On the other hand, the laser emission device of the laser engraving machine may deviate in its emission angle and position during long-term use, requiring frequent calibration and adjustment, which is cumbersome and affects work efficiency. In addition, the waste chips and fumes generated when laser engraving metal rings by existing laser engraving machines can easily permeate the working environment, not only polluting the environment but also potentially harming the health of operators and affecting the normal operation of the laser engraving machine.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] like Figure 1 - Figure 5 As shown, the present application provides a metal ring laser engraving machine 1, comprising:

[0031] The machine base 10 is fixedly mounted with a mounting frame 11, and a laser emitting device 20 is slidably mounted on the mounting frame 11.

[0032] A worktable 30 is disposed on the machine base 10 and located below the laser emitting device 20. The worktable 30 includes a tiltable mounting base 40 and a turntable 50. The turntable 50 is rotatably mounted on the tiltable mounting base 40. Multiple placement slots 51 are spaced apart along the circumferential direction inside the turntable 50. Positioning posts 511 are fixedly installed in the placement slots 51. Arc-shaped clamps 52 are slidably installed on the inner sidewall of the placement slots 51. Springs 53 connect the arc-shaped clamps 52 and the slot wall of the placement slots 51. A first motor 41 is fixedly mounted on the tiltable mounting base 40. The output shaft of the first motor 41 passes through the tiltable mounting base 40 and is connected to the bottom of the turntable 50 to drive the turntable 50 to rotate.

[0033] The machine base 10 serves as the main body of the equipment. A mounting bracket 11 is fixed on it, allowing the laser emitting device 20 to slide and move horizontally. The worktable 30 is located below the laser emitting device 20, and its key feature is the cooperation between the tiltable mounting base 40 and the turntable 50. The turntable 50 has circumferentially distributed placement slots 51 equipped with positioning posts 511. The arc-shaped clamping plate 52 on the inner sidewall is connected to the slot wall via springs 53. The first motor 41 drives the turntable 50 to rotate.

[0034] The positioning pin 511 can be inserted into the inner hole of the metal ring for initial positioning. The arc-shaped clamp 52 is tightly attached to the outer wall of the metal ring under the action of the spring 53, forming a double fixing structure of inner and outer clamping, which effectively prevents the metal ring from shifting during laser engraving and improves the engraving accuracy. The multiple placement slots 51 on the turntable 50 can load multiple metal rings at the same time. The first motor 41 drives the turntable 50 to rotate, so that the metal rings enter the laser engraving area in sequence, eliminating the need for frequent loading and unloading and greatly improving processing efficiency.

[0035] The combination of positioning pin 511, arc-shaped clamping plate 52 and spring 53 forms an adaptive clamping structure, which solves the problem of unstable positioning; at the same time, the circumferential placement slot 51 of turntable 50 and the motor drive design realize automated batch processing and improve work efficiency.

[0036] Furthermore, the tiltable mounting base 40 includes a fixed base 42 fixed to the machine base 10. The top of the fixed base 42 is rotatably connected to a tilting base 43 via a rotating shaft. The top of the tilting base 43 is provided with a mounting groove 431 for mounting the turntable 50. A tilting drive mechanism for driving the tilting base 43 to rotate is provided on one side of the fixed base 42.

[0037] The fixed seat 42 and the tilting seat 43 are connected by a rotating shaft. The top of the tilting seat 43 is provided with a mounting groove 431 to fix the turntable 50. The tilting drive mechanism on one side of the fixed seat 42 can drive the tilting seat 43 to rotate. The worktable 30 has an angle adjustment function, which can flexibly adjust the relative angle between the metal ring and the laser beam. When it is necessary to engrave curved or tilted surfaces, the angle of the tilting seat 43 is adjusted by the tilting drive mechanism so that the laser beam irradiates the surface of the metal ring perpendicularly, avoiding deformation of the engraved pattern due to angle deviation, and expanding the equipment's adaptability to processing metal rings of different shapes.

[0038] Furthermore, the tilting drive mechanism includes an electric push rod 44 fixed to the fixed base 42, and the telescopic end of the electric push rod 44 is hinged to the side of the tilting base 43.

[0039] Using an electric actuator 44 as the drive mechanism has the advantage of enabling precise control and automated adjustment of the tilt angle. The electric actuator 44 can be precisely controlled by the electronic control system to adjust the tilt angle of the tilting seat 43 accurately (e.g., any adjustment within the range of 0°-45°), which is more efficient and has a smaller angle error compared to manual adjustment. At the same time, it can be linked with the equipment control system to realize automatic angle switching during the engraving process, adapting to the needs of complex engraving processes.

[0040] Furthermore, an annular slider 54 is fixedly installed at the bottom of the turntable 50, and an annular guide rail 432 is correspondingly provided at the top of the tilting seat 43. The annular slider 54 is slidably connected to the annular guide rail 432, and the cross-section of the annular guide rail 432 is T-shaped.

[0041] A ring-shaped slider 54 is fixed to the bottom of the turntable 50, and a ring-shaped guide rail 432 is provided on the top of the tilting seat 43, with a T-shaped cross-section. This design ensures the smooth rotation and prevents the turntable 50 from slipping off. The cooperation between the ring-shaped slider 54 and the ring-shaped guide rail 432 keeps the turntable 50 concentric during rotation, preventing wobbling; the T-shaped cross-section of the guide rail restricts the vertical displacement of the slider, preventing the turntable 50 from slipping off during high-speed rotation or tilt adjustment, thus improving the safety and reliability of the equipment operation.

[0042] Furthermore, an angle locking mechanism 45 is provided between the fixed base 42 and the tilting base 43. The angle locking mechanism 45 includes a mounting block 451 fixed on the fixed base 42, a locking rod 452 passing through the mounting block 451, and a plurality of locking grooves 433 formed on the side of the tilting base 43. One end of the locking rod 452 is engaged with the locking groove 433, and the other end is fixedly connected to a pull ring 453.

[0043] To fix the angle of the tilting seat 43, an angle locking mechanism 45 is provided between the fixed seat 42 and the tilting seat 43, including a mounting block 451, a locking rod 452, a locking groove 433, and a pull ring 453. One end of the locking rod 452 is engaged in the locking groove 433 on the side of the tilting seat 43, and the other end is connected to the pull ring 453. The beneficial effect of the angle locking mechanism 45 is to ensure that the tilting seat 43 maintains a fixed angle during the engraving process, avoiding angle deviation due to vibration or other factors. When the tilting seat 43 is adjusted to the target angle, the locking rod 452 is engaged in the corresponding locking groove 433 under the action of the pull ring 453, forming a mechanical lock, preventing the change of the worktable angle 30 from affecting the consistency of the engraved pattern, which is especially suitable for batch production scenarios that require repeated processing of the same angle.

[0044] Furthermore, a return spring 454 is sleeved on the outer side of the locking rod 452, and the two ends of the return spring 454 abut against the mounting block 451 and the pull ring 453 respectively.

[0045] The beneficial effect of the return spring 454 is improved ease of angle adjustment. When the tilt angle needs to be adjusted, pulling the pull ring 453 disengages the locking rod 452 from the locking groove 433, at which point the return spring 454 is compressed. After adjustment, releasing the pull ring 453 causes the spring 53 to push the locking rod 452 into the new locking groove 433 automatically, eliminating the need for manual alignment, reducing operation steps, and improving adjustment efficiency. From an ergonomic perspective, the return spring 454 simplifies the operation process and avoids potential positioning inaccuracies or jamming when manually inserting the locking rod 452. Especially in scenarios involving frequent angle adjustments, it significantly reduces the operator's workload, conforming to the ease-of-use design principles of industrial equipment.

[0046] Furthermore, the bottom of the placement groove 51 of the turntable 50 is provided with a chip removal hole 55 that extends through to the bottom surface of the turntable 50. The chip removal hole 55 is connected to the chip collection cavity inside the worktable 30, and the diameter of the chip removal hole 55 gradually increases in the direction away from the placement groove 51.

[0047] To address the waste generated during laser engraving, a chip removal hole 55 is provided at the bottom of the placement groove 51 of the turntable 50, extending through to the bottom surface of the turntable 50 and communicating with the chip collection cavity within the worktable 30. The diameter of the chip removal hole 55 gradually increases in the direction away from the placement groove 51. The beneficial effects of this chip removal structure are timely cleaning of waste, maintaining a clean working environment, and preventing equipment malfunctions. Metal fragments generated during laser engraving of metal rings can fall into the chip collection cavity through the chip removal hole 55. The enlarged hole diameter design (such as a trumpet shape) prevents waste from accumulating and clogging the channel, ensuring smooth chip removal. Centralized collection of waste reduces obstruction of the laser beam path, avoiding impact on engraving quality, and also reduces wear on internal equipment parts (such as motors and guide rails), extending the equipment's service life.

[0048] Furthermore, the inner wall of the placement groove 51 is provided with a sliding groove, a sliding rod is fixedly installed on one side of the arc-shaped clamp 52, the sliding rod is slidably connected to the sliding groove, and the spring 53 is sleeved on the outside of the sliding rod.

[0049] The combined design of the arc-shaped clamping plate 52 with the sliding groove, sliding rod, and spring 53 enhances the flexibility and stability of the clamping structure. When the metal ring is placed in the placement groove 51, the arc-shaped clamping plate 52 slides along the sliding rod towards the outer wall of the metal ring under the elastic force of the spring 53 until it tightly adheres to and fixes the metal ring. The sliding design of the sliding rod within the sliding groove ensures the smooth movement of the arc-shaped clamping plate 52. Simultaneously, the elastic force of the spring 53 can be automatically adjusted according to the size of the metal ring, forming a tight and uniform clamping force, effectively preventing deformation of the metal ring due to excessive clamping or displacement due to insufficient clamping force. Furthermore, this design facilitates the quick installation and removal of the metal ring, improving the ease of operation and processing efficiency of the equipment.

[0050] Furthermore, a protective cover 12 is fixedly installed on the top of the machine base 10, and an opening is provided on one side of the protective cover 12, with a closed door rotatably connected to the edge of the opening.

[0051] The protective cover 12 provides the benefit of isolating laser radiation and flying debris, thus improving the safety of equipment use. The protective cover 12 can block laser beam leakage, preventing injury to the operator's eyes or skin; when the closed door is closed, it can prevent metal debris from flying during laser engraving, while also reducing the transmission of processing noise, creating a safe and healthy working environment for operators.

[0052] Furthermore, an exhaust fan 13 is fixedly installed on the top of the protective cover 12, and the air inlet of the exhaust fan 13 is connected to an exhaust pipe 14, one end of which extends into the protective cover 12.

[0053] The beneficial effect of the ventilation system is to promptly remove fumes and harmful gases generated during laser engraving, improving the working environment. High temperatures during metal laser engraving produce metal dust and volatile gases. The exhaust fan 13 extracts and filters the contaminated air from the protective cover 12 through the exhaust pipe 14 (an external dust removal device can be connected), reducing the concentration of harmful substances in the air, protecting the respiratory health of operators, and preventing fumes from adhering to the laser lens and affecting the optical path accuracy, thus ensuring the stability of the engraving quality.

[0054] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
