Description

Technical Field

[0001] This invention relates to the field of tire engraving technology, specifically to a tire engraving laser generator and its optical path structure. Background Technology

[0002] The tire engraving laser generator and its optical path structure are specialized laser devices used for laser engraving on tire surfaces.

[0003] Conventional tire molding processes involve printing characters, codes, and other information onto the tire surface through a high-temperature vulcanization process in a vulcanizing chamber. This method is time-consuming, costly, and involves complex processes such as mold making, mold selection, inlaying, and printing. In contrast, laser engraving technology can directly engrave characters onto the tire surface at a lower cost and can achieve a fully automated process.

[0004] Conventional engraving methods use fiber lasers. However, since the wavelength of this laser is 1064nm, it has a lower absorption coefficient on rubber compared to the 10600nm carbon dioxide laser, making it prone to carbonization during the marking process. Therefore, the industry trend is to use carbon dioxide laser technology for tire engraving.

[0005] However, due to the harsh environment of tire production, dust and high temperature have a significant impact on the equipment, which can easily lead to damage to the optical path. Furthermore, when transporting tires, the shaking can be transmitted to the engraving mechanism, resulting in defective products. In addition, because the tire sidewalls are uneven and tire styles vary, laser engraving needs to be adapted to the tire surface. Summary of the Invention

[0016] Furthermore, a sealing groove is provided on the side of the laser adapter block near the carbon dioxide laser. The sealing groove has a diameter of 2 mm and a depth of 1 mm. Two symmetrically distributed guide grooves are fixedly installed on the side of the laser adapter block away from the carbon dioxide laser.

[0017] Furthermore, the beam expander mounting mechanism has a sealing groove on the side near the galvanometer, the sealing groove having a diameter of 3mm and a depth of 1mm.

[0018] Furthermore, several rotating shafts are rotatably mounted on the periphery of the connecting disk, and several sliding grooves are opened on the upper side of the stabilizing disk, with limit grooves opened on both opposite sides of the inner wall of the sliding grooves.

[0026] 4. By combining a scanning mechanism and a control console, this invention can scan the surface of a tire, and the control console controls the operation of an electric telescopic rod, thereby adjusting the angle of the engraving mechanism to achieve an adaptive engraving effect.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1: A tire engraving laser generator and its optical path structure, as follows Figures 1-15 As shown,

[0048] The device includes a main body 1, a robotic arm 3 on one side of the main body 1, and a control console 2 on the other side of the robotic arm 3. The control console 2 can control the robotic arm 3, and the scanning mechanism 4 transmits data to the control console 2 by scanning the surface of the tire. The control console 2 can adjust the engraving mechanism 5. The control console 2 controls the robotic arm 3 and the connection between the scanning mechanism 4 and the control console 2 are existing technologies and will not be described in detail here. A stabilizing mechanism 6 is rotatably installed at one end of the robotic arm 3. An adjusting mechanism 7 is movably connected to the lower end of the stabilizing mechanism 6. The engraving mechanism 5 is fixedly installed at the lower end of the adjusting mechanism 7. The engraving mechanism 5 includes a carbon dioxide laser 51, and a laser adapter block 52 is fixedly installed at one end of the carbon dioxide laser 51.

[0049] A sealing groove 521 is formed on the side of the laser adapter block 52 closest to the carbon dioxide laser 51. The sealing groove 521 has a diameter of 2mm and a depth of 1mm. A sealing ring is installed inside the sealing groove 521 to seal and prevent dust from affecting the carbon dioxide laser 51. The sealing ring is existing technology and will not be described in detail here, nor is it shown in the figure. Two symmetrically distributed guide grooves 522 are fixedly installed on the side of the laser adapter block 52 furthest from the carbon dioxide laser 51. The guide grooves 522 can accommodate the beam expander mounting machine. The structure 53 serves as a guide during installation, improving installation efficiency. A beam expander mounting mechanism 53 is fixedly installed on the side of the laser adapter block 52 away from the carbon dioxide laser 51. A sealing groove 531 is opened on the side of the beam expander mounting mechanism 53 near the galvanometer 55. The sealing groove 531 has a diameter of 3mm and a depth of 1mm. A sealing ring is installed in the sealing groove 531, thereby sealing the optical path and preventing dust from affecting the carbon dioxide laser 51. The sealing ring is existing technology and will not be described in detail here, nor is it shown in the figure.

[0050] A beam expander 56 is fixedly installed inside the beam expander mounting mechanism 53. One end of the beam expander 56 is fixedly connected to the laser adapter block 52, and the end of the beam expander 56 away from the laser adapter block 52 is fixedly connected to the galvanometer adapter block 54. A galvanometer adapter block 54 is fixedly installed at the end of the beam expander mounting mechanism 53 away from the laser adapter block 52. A galvanometer 55 is fixedly installed on the side of the galvanometer adapter block 54 away from the beam expander mounting mechanism 53. A scanning mechanism 4 is fixedly installed at one end of the engraving mechanism 5.

[0051] The engraving mechanism 5 has an emission port 555 at one end, which is a laser outlet. The stabilizing mechanism 6 includes a fixed body 61, with a connecting plate 62 fixedly installed at the lower end of the fixed body 61. A stabilizing plate 63 is provided on the lower side of the connecting plate 62. The adjusting mechanism 7 includes a fixed plate 73, with several electric telescopic rods 72 on the upper side of the fixed plate 73. A ball is provided between the fixed plate 73 and the electric telescopic rods 72. The fixed plate 73 is movably connected to the electric telescopic rods 72 through the ball. A ball is rotatably installed on the end of the electric telescopic rod 72 away from the fixed plate 73. A groove 74 is opened on the upper side of the fixed plate 73, and a rotating ball 71 is movably installed on the inner wall of the groove 74.

[0052] The engraving mechanism 5 is made of 6061 aluminum alloy, which ensures the overall strength of the engraving mechanism 5. At the same time, the 6061 aluminum alloy has a high thermal conductivity, which further ensures the heat dissipation effect of the engraving mechanism 5 and avoids the impact of high temperature on the carbon dioxide laser 51. 6061 aluminum alloy is existing technology and will not be described in detail here. The engraving mechanism 5 is also equipped with a protective shell made of 6061 aluminum alloy. When the engraving mechanism 5 is rotated to the maximum angle, magnet 67 and magnet 68 will still not come into contact.

[0053] Example 2: A tire engraving laser generator and its optical path structure, as follows Figures 1-15 As shown, the device includes a main body 1, a robotic arm 3 on one side of the main body 1, a control console 2 on one side of the robotic arm 3, a stabilizing mechanism 6 rotatably mounted on one end of the robotic arm 3, an adjusting mechanism 7 movably connected to the lower end of the stabilizing mechanism 6, an engraving mechanism 5 fixedly mounted on the lower end of the adjusting mechanism 7, a scanning mechanism 4 fixedly mounted on one end of the engraving mechanism 5, and a transmission port 555 on one end of the engraving mechanism 5. The stabilizing mechanism 6 includes a fixed body 61, and a connecting plate 62 fixedly mounted on the lower end of the fixed body 61.

[0054] A number of rotating shafts 611 are rotatably mounted around the connecting plate 62. A stabilizing plate 63 is provided on the lower side of the connecting plate 62. The lower side of the stabilizing plate 63 is movably connected to one end of the electric telescopic rod 72 through a ball. A support body 64 is fixedly installed in the middle of the lower side of the stabilizing plate 63. The end of the support body 64 away from the stabilizing plate 63 is movably connected to the rotating ball 71. A number of sliding grooves 66 are opened on the upper side of the stabilizing plate 63. A magnet 68 is fixedly installed on one side of the inner wall of the sliding groove 66. A magnet 67 is slidably installed on the inner wall of the sliding groove 66. The magnetic poles of the magnet 67 are the same as the magnetic poles of the magnet 68. At the same time, the initial position of the magnet 67 is in the middle of the sliding groove 66, so that when the fixed body 61 and the connecting plate 62 swing, the magnet 67 has enough sliding space.

[0055] A support rod 65 is rotatably mounted on one end of magnet 67. The end of the support rod 65 away from magnet 67 is rotatably connected to the outer side of rotating shaft 611. Limiting slide rods 610 are fixedly mounted on both opposite sides of magnet 67. The end of the limiting slide rod 610 away from magnet 67 is slidably connected to the inner wall of limiting groove 69. When the limiting slide rod 610 and limiting groove 69 are used together, magnet 67 receives maximum upward pulling force when it is located in the middle of limiting groove 69. At this time, the limiting slide rod 610 can restrict the position of magnet 67 and prevent it from being pulled upward. Magnet 67 is pulled out to the outside of the limiting groove 69, which can guide the sliding of magnet 67. The stabilizing plate 63 is relatively stationary relative to the sliding of magnet 67. Therefore, the sliding of magnet 67 can eliminate the shaking from above, thereby ensuring the stability of engraving mechanism 5. Limiting grooves 69 are opened on both sides of the inner wall of slide 66. Adjustment mechanism 7 includes fixed plate 73. Several electric telescopic rods 72 are provided on the upper side of fixed plate 73. A ball is provided between fixed plate 73 and electric telescopic rods 72.

[0056] The fixed plate 73 is movably connected to the electric telescopic rod 72 via a ball. The electric telescopic rod 72 is existing technology and will not be described in detail here. A ball is rotatably installed on the end of the electric telescopic rod 72 away from the fixed plate 73. A groove 74 is provided on the upper side of the fixed plate 73, and a rotating ball 71 is movably installed on the inner wall of the groove 74.

[0057] The working principle of the above embodiment is as follows: the tire is transported to the bottom of the carving mechanism 5 by the conveying device, and the clamping mechanism positions and fixes the tire. The conveying device and clamping mechanism are existing technologies and will not be described in detail here. At this time, the scanning mechanism 4 can scan the outside of the tire and transmit the scanning information to the control console 2. The control console 2 controls the electric telescopic rod 72 to operate. At this time, the electric telescopic rod 72 retracts, the corresponding electric telescopic rod 72 on one side unfolds, and the other electric telescopic rods 72 operate accordingly, thereby completing the angle adjustment of the carving mechanism 5. At the same time, the vibration generated when transporting the tire is transmitted to the robotic arm 3 and the fixed body 61. The shaking fixed body 61 transmits the shaking to the connecting plate 62. At the same time, the connecting plate 62 pulls the support rod 65. The support rod 65 pulls the magnet 67 to slide away from the magnet 68 inside the slide groove 66. At the same time, the corresponding magnet 67 slides away from or closer to the magnet 68 inside the slide groove 66, thereby completing the cancellation of the shaking.

[0058] When engraving begins, the CO2 laser 51 generates a high-power infrared laser beam. With the fixed support of the laser adapter block 52, the output port of the CO2 laser 51 is horizontally aligned with the subsequent optical path, ensuring the beam does not deviate. At this time, supported by the beam expander mounting mechanism 53, the beam expander 56 can be fixed and its horizontal and vertical position adjusted. Simultaneously, the beam expander 56 transforms the thin laser beam generated by the CO2 laser 51 into a coarse parallel beam, thereby increasing the scanning range and focusing energy of the galvanometer 55. The galvanometer adapter block 54 ensures that the expanded parallel beam enters the galvanometer 55 vertically and stably. The two high-speed oscillating mirrors inside the galvanometer 55 control the movement of the laser beam, focusing it onto the tire surface for engraving. Simultaneously, the heat generated by the laser is dissipated outwards through the 6061 aluminum alloy material, achieving heat dissipation. Furthermore, the combination of the sealing grooves 521 and 531 with their internal sealing rings prevents smoke and dust generated during the engraving process from entering the engraving mechanism 5 and causing optical path contamination.

[0059] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
