Description

Technical Field

[0001] The invention belongs to the technical field of carbon dioxide lasers, and in particular relates to an intelligent radio frequency carbon dioxide laser with a lens adjustment function. Background Art

[0002] Smart RF CO2 lasers are devices that use RF excitation technology to excite CO2 gas to produce lasers. These lasers are widely used in industrial processing, scientific research, and medical fields due to their unique working mode and performance characteristics. Smart RF CO2 lasers are mainly composed of a housing, a lens assembly, and multiple optical components. When working, the lasers generated by multiple optical components pass through the lens assembly and are emitted out of the housing, forming a light spot on the target object. The size of the light spot can be adjusted by adjusting the position of the lens assembly or multiple optical components in the housing.

When the position of the lens assembly or multiple optical assemblies is adjusted to adjust the size of the light spot, the shell needs to be disassembled and assembled, and the convenience of adjusting the light spot is insufficient. In addition, during the process of adjusting the position of the lens assembly, dust and other impurities are easily raised due to the movement of the lens assembly. These impurities float around the lens assembly and easily affect the laser beam quality, causing changes in the size, shape and uniformity of the light spot, and the reliability of the light spot adjustment is insufficient.

[0042] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0043] Example

[0044] like Figure 1 - Figure 7 As shown, it is the first embodiment of the present invention, which provides an intelligent radio frequency carbon dioxide laser with a lens adjustment function, including a housing 10, a slide rail 101 is arranged inside the housing 10, a lens assembly 11 and a plurality of optical components 12 are slidably connected to the slide rail 101, and the optical component 12 includes a beam expander assembly 121, an aperture assembly 122, a pump cavity assembly 123, a Q switch assembly 124, and a total reflection mirror assembly 125; a displacement mechanism 20, the displacement mechanism 20 is arranged at the bottom of the housing 10, and the lens assembly 11 and the plurality of optical components 12 are respectively moved along the slide rail 101 through the displacement mechanism 20; the displacement mechanism 20 includes a plurality of adjustment parts 21 corresponding to the lens assembly 11 and the plurality of optical components 12, and the plurality of adjustment parts 21 are driven by a driving part 22 , and a switching mechanism 23 is arranged inside the driving part 22, the switching mechanism 23 can switch the driving part 22 to the corresponding adjusting part 21 respectively, and is used to drive the corresponding adjusting part 21 respectively; wherein the adjusting part 21 includes a first pulley 211 rotatably connected to the driving part 22, and the end of the slide rail 101 away from the driving part 22 is rotatably connected to the second pulley 212, and a transmission belt 213 is connected between the first pulley 211 and the second pulley 212; one side of the plurality of transmission belts 213 is respectively connected to the bottom of the lens assembly 11 and the plurality of optical components 12; a dust removal mechanism 30, two dust removal mechanisms 30 are arranged and are respectively located on both sides of the inner wall of the shell 10, the dust removal mechanism 30 is connected to the lens assembly 11, and is used to absorb impurities such as dust, and the dust removal mechanism 30 includes an electrostatic suction cup 31 and a cleaning roller 32.

[0045] It should be noted that a connecting sheet metal 215 is provided between the lens assembly 11 and the multiple optical assemblies 12 and the transmission belt 213. One end of the connecting sheet metal 215 is fixedly connected to one side of the transmission belt 213, and the other end of the connecting sheet metal 215 is fixedly connected to the corresponding lens assembly 11 or the multiple optical assemblies 12, so as to drive the corresponding lens assembly 11 or the multiple optical assemblies 12 to slide along the slide rail 101 after the transmission belt 213 is activated.

[0046] When the present invention is in use, the lasers generated by the multiple optical components 12 pass through the lens component 11 and are emitted outside the housing 10, thereby forming a light spot outside. The operator operates the displacement mechanism 20 from the outside of the housing 10, so that the switching mechanism 23 is actuated to drive the driving part 22 to switch to the corresponding adjustment part 21 respectively, and the driving part 22 drives the corresponding adjustment part 21 to operate, so that the adjustment part 21 drives the corresponding lens component 11 or multiple optical components 12 to slide inside the housing 10, so that the position of the lens component 11 or multiple optical components 12 in the housing 10 can be adjusted from the outside of the housing 10 to adjust the light spot. The size of the housing 10 is avoided from being disassembled and assembled during adjustment in the traditional method, thereby improving the convenience of adjusting the light spot. After the electrostatic suction cup 31 works, it absorbs dust and other impurities raised when the lens assembly 11 moves, thereby reducing the influence of impurities on the laser beam quality and improving the reliability of the light spot adjustment. During the movement of the lens assembly 11, the cleaning roller 32 is also driven to move on the electrostatic suction cup 31 to remove impurities absorbed by the electrostatic suction cup 31, thereby reducing the accumulation of excessive impurities on the electrostatic suction cup 31 and preventing the electrostatic suction cup 31 from continuing to absorb impurities, thereby extending the service life of the electrostatic suction cup 31 and improving the convenience of absorbing impurities.

[0047] In order to ensure the normal operation of the entire laser, a water cooling mechanism is also provided at the bottom of the shell 10. The water cooling mechanism can be simply provided with a pipeline design, that is, it includes a water inlet and a water outlet, and the entire pipeline is located inside the shell 10 to increase the heat dissipation performance of the laser.

[0048] Example

[0049] Reference Figure 1 - Fig.12 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0050] like Figure 7 , Figure 8 and Fig. 9 As shown, the driving part 22 includes a driving cylinder 221 rotatably connected to the shell 10, and a plurality of limit blocks 222 are arranged inside the driving cylinder 221 along the vertical direction. The plurality of limit blocks 222 respectively correspond to the plurality of first pulleys 211, and the limit blocks 222 are slidingly connected to the driving cylinder 221 along the radial direction. A spring 223 is connected between one end of the limit block 222 close to the first pulley 211 and the driving cylinder 221, and a limit hole 214 is provided on the inner wall of one side of the first pulley 211 close to the driving cylinder 221, and the limit block 222 is slidably matched with the limit hole 214.

[0051] It should be noted that rubber strips are arranged between the lens assembly 11 and the multiple optical assemblies 12 and the slide rail 101, which are used to increase the friction between the lens assembly 11 and the multiple optical assemblies 12 and the slide rail 101. The friction is greater than the friction between the outer wall of the driving cylinder 221 and the inner wall of the first pulley 211 when the driving cylinder 221 rotates. When the driving cylinder 221 drives the corresponding adjustment part 21 to move, the driving cylinder 221 is prevented from also driving the remaining adjustment parts 21 to move, so as to avoid affecting the position of the remaining lens assembly 11 or the multiple optical assemblies 12 when the position of one of the lens assembly 11 and the multiple optical assemblies 12 is adjusted.

[0052] like Figure 7 , Figure 8 and Fig. 9 As shown, the switching mechanism 23 includes an adjusting shaft 231 slidably connected to the inside of the driving cylinder 221, and the adjusting shaft 231 is also rotatably connected to the driving cylinder 221. The end of the adjusting shaft 231 close to the adjusting portion 21 is fixedly connected with a thin shaft portion 232, and the outer wall of the thin shaft portion 232 is fixedly connected with a plurality of limit rings 233 along the vertical direction. The plurality of limit rings 233 correspond to the plurality of limit blocks 222 respectively, and the distance between two adjacent limit rings 233 is greater than the distance between two adjacent limit blocks 222.

[0053] It should be noted that the diameter of the thin shaft portion 232 is smaller than the diameter of the adjusting shaft 231. The top of the adjusting shaft 231 extending out of the shell 10 is provided with a connecting groove 237. The upper and lower sides of the limiting ring 233 are both inclined surfaces, which facilitates the end of the limiting block 222 close to the thin shaft portion 232 to move from the outer side of the thin shaft portion 232 along the inclined surface to the outer side of the limiting ring 233, that is, it is convenient for the limiting ring 233 to push the limiting block 222 to move. The outer wall of the thin shaft portion 232 and the end of the limiting block 222 close to the thin shaft portion 232 are both roughened. When the end of the limiting block 222 close to the thin shaft portion 232 abuts against the outer wall of the thin shaft portion 232, the end of the limiting block 222 close to the first pulley 211 is located inside the driving cylinder 221 and does not contact the first pulley 211.

[0054] According to the above structure, when it is necessary to adjust the positions of the lens assembly 11 and multiple optical components 12, the operator uses a tool to drive the adjustment shaft 231 to move up and down along the driving cylinder 221 through the connecting groove 237, and the adjustment shaft 231 drives the limiting ring 233 to move up and down along the inner wall of the driving cylinder 221 through the thin shaft portion 232. Since the distance between two adjacent limiting rings 233 is greater than the distance between two adjacent limiting blocks 222, only one limiting ring 233 among the multiple limiting rings 233 can correspond to one limiting block 222 at a time, and the limiting ring 233 pushes one limiting block 222 to move along the radial direction of the driving cylinder 221 toward the side close to the first pulley 211, so that the limiting block 222 is inserted into the corresponding limiting hole 214, and the driving cylinder 221 and the first pulley 211 corresponding to the limiting hole 214 are limited. At this time, the spring 223 corresponding to the limiting block 222 is squeezed, and the remaining limiting blocks 222 are locked. Under the elastic action of the corresponding spring 223, block 222 pushes the limit block 222 to move toward the side close to the thin shaft portion 232, so that one end of the limit block 222 close to the thin shaft portion 232 abuts against the outer wall of the thin shaft portion 232, preventing the thin shaft portion 232 and the adjustment shaft 231 from moving downward along the driving cylinder 221 under the action of their own gravity. The operator rotates the driving cylinder 221, and the driving cylinder 221 drives a first pulley 211 to rotate. The first pulley 211 drives the second pulley 212 and the transmission belt 213 to rotate, so that the transmission belt 213 drives the corresponding lens assembly 11 or optical assembly 12 to slide along the slide rail 101, thereby adjusting the position of the lens assembly 11 or optical assembly 12 in the housing 10, so as to facilitate the adjustment of the size of the light spot by adjusting the position of the lens assembly 11 or optical assembly 12 from the outside of the housing 10, avoiding the need to disassemble and assemble the housing 10 during adjustment, and improving the convenience of light spot adjustment.

[0055] After the driving cylinder 221 drives one of the first pulleys 211 to rotate, the limiting holes 214 and the limiting blocks 222 corresponding to the remaining first pulleys 211 may be staggered with the driving cylinder 221, so that when the adjusting shaft 231 drives the thin shaft portion 232 and the limiting ring 233 to move up and down, it is difficult for the limiting block 222 to be inserted into the limiting hole 214. At this time, the end of the limiting block 222 close to the thin shaft portion 232 hinders the limiting ring 233 from moving downward or upward. In this case, due to the distance between the two adjacent limiting rings 233 The operator drives the thin shaft portion 232 and the limit ring 233 to move in a direction opposite to the side where the limit ring 233 is blocked by the limit block 222 through the adjustment shaft 231, so that the plurality of limit rings 233 are not in contact with the corresponding limit blocks 222. At this time, the operator uses a tool to rotate the adjustment shaft 231 through the connecting groove 237, and the adjustment shaft 231 drives the thin shaft portion 232 to rotate. Since the outer wall of the thin shaft portion 232 and the end of the limit block 222 close to the thin shaft portion 232 are both The surface is roughened, and at this time, the limit block 222 abuts against the outer wall of the thin shaft portion 232 under the elastic action of the spring 223, so that when the thin shaft portion 232 rotates, the drive cylinder 221 is also driven to rotate through the limit block 222, so that the limit block 222 and the limit hole 214 are aligned along the radial direction of the drive cylinder 221. In order to facilitate the operator to understand whether the limit block 222 and the limit hole 214 are aligned, the operator can rotate the adjustment shaft 231 while moving the adjustment shaft 231 in a direction, which is the limit ring 2 When the operator is unable to move the adjusting shaft 231 in the direction of the side blocked by the limit block 222, it means that the limit ring 233 is still blocked by the limit block 222, and the limit block 222 is not aligned with the limit hole 214 at this time; when the operator is able to move the adjusting shaft 231 in the direction, it means that the limit ring 233 is not blocked by the limit block 222, and the limit block 222 is aligned with the limit hole 214 at this time, and the limit block 222 is pushed by the limit ring 233 to be inserted into the inside of the limit hole 214 along the radial direction of the driving cylinder 221.

[0056] like Figure 7 , Figure 8 and Fig. 9 As shown, a protrusion 234 is fixedly connected to the outer side of one end of the driving cylinder 221 extending out of the shell 10 at the top, a protrusion ring 102 is provided below the protrusion 234, the protrusion ring 102 is fixedly connected to the outer wall of the shell 10, and a limit cover 235 is provided above the protrusion 234, and the limit cover 235 is threadedly connected to the protrusion ring 102 along the vertical direction.

[0057] It should be noted that a through hole is formed on the top of the limiting cover 235 , the diameter of which is larger than the outer diameter of the driving cylinder 221 and smaller than the outer diameter of the protrusion 234 , and the upper end of the driving cylinder 221 extends out of the limiting cover 235 through the through hole.

[0058] According to the above structure, when there is no need to adjust the position of the lens assembly 11 and the multiple optical components 12, it is necessary to limit the rotation of the driving cylinder 221. The operator rotates the limit cover 235 to make the limit cover 235 move downward along the convex ring 102. The distance between the limit cover 235 and the convex ring 102 in the vertical direction is reduced, so that the limit cover 235 and the convex ring 102 clamp the protrusion 234, limiting the rotation of the protrusion 234, thereby limiting the rotation of the driving cylinder 221. This is convenient for avoiding the operator from accidentally rotating the driving cylinder 221 or the driving cylinder 221 accidentally shaking to rotate the first pulley 211 when the position of the lens assembly 11 and the multiple optical components 12 is not required to be adjusted.

[0059] like Figure 7 , Figure 8 and Fig. 9 As shown, a plurality of scales 236 are provided on the outer side of one end of the top of the adjusting shaft 231 extending out of the driving cylinder 221 . The plurality of scales 236 are distributed along the vertical direction and correspond to the plurality of limit blocks 222 respectively.

[0060] It should be noted that the top of the connecting groove 237 passes through the top of the driving cylinder 221 and extends to the outside of the driving cylinder 221. The upper surface of the top of the driving cylinder 221 is parallel to the horizontal plane, and the upper surface is parallel to the scale 236. The upper surface is used to indicate the scale 236. When a scale 236 is aligned with the upper surface of the top of the driving cylinder 221, the limit block 222 corresponding to the scale 236 is inserted into the interior of the limit hole 214, and the distance between two adjacent limit rings 233 is equal to the distance between two adjacent limit blocks 222 plus the distance between two adjacent scales 236.

[0061] According to the above structure, when the operator moves the adjustment shaft 231 up and down in the vertical direction from the outside of the shell 10, in order to enable the operator to understand which adjustment part 21 the switching mechanism 23 causes the driving part 22 to switch to, the operator can observe the alignment of the scale 236 with the top upper surface of the driving cylinder 221. Since multiple scales 236 correspond to multiple limit blocks 222 respectively, and the distance between two adjacent limit rings 233 is equal to the distance between two adjacent limit blocks 222 plus the distance between two adjacent scales 236, when the top upper surface of the driving cylinder 221 is aligned with a scale 236, it means that the limit block 222 corresponding to the scale 236 is inserted into the inside of the limit hole 214, so that the operator can understand which adjustment part 21 the driving part 22 switches to, so that when adjusting the position, the operator can understand which one of the lens assembly 11 and the multiple optical assemblies 12 is being adjusted.

[0062] In order to allow the operator to observe the positions of the lens assembly 11 and the multiple optical components 12 after they move during the process of adjusting the positions outside the shell 10, a strip observation window is provided on the top of the shell 10 along the sliding direction of the slide rail 101. The strip observation window is transparent in design, and a detachable shading plate is provided on the outside of the strip observation window. When the operator does not need to observe, the shading plate can be closed to prevent light from passing through the strip observation window.

[0063] like Fig.10 , Fig.11 and Fig.12 As shown, the dust removal mechanism 30 also includes a rotating column 33 slidably connected to the bottom of the shell 10, the rotating column 33 is rotatably connected to the lens assembly 11, the cleaning roller 32 is slidably connected to the top of the rotating column 33 along the vertical direction, the electrostatic suction cup 31 is fixedly connected to the inner wall of the shell 10, the outer side of the cleaning roller 32 is in contact with the electrostatic suction cup 31, a connecting plate 34 is provided above the electrostatic suction cup 31, the connecting plate 34 is fixedly connected to the inner wall of the shell 10, the top of the cleaning roller 32 is slidably connected to the connecting plate 34, and a material changing port 103 is provided on the inner wall of the shell 10, and the material changing port 103 is located at one end of the electrostatic suction cup 31.

[0064] It should be noted that the length dimension of the material replacement port 103 along the vertical direction is greater than the length dimension of the cleaning roller 32 along the vertical direction.

[0065] According to the above structure, after the electrostatic suction cup 31 works, it absorbs impurities such as dust raised when the lens assembly 11 moves, thereby reducing the situation where impurities affect the beam quality of the laser. After the lens assembly 11 moves, it drives the rotating column 33 to move along the bottom of the shell 10. The rotating column 33 drives the cleaning roller 32 to move along the electrostatic suction cup 31 to clean the impurities adsorbed by the electrostatic suction cup 31. During the movement of the cleaning roller 32, the top of the cleaning roller 32 slides along the connecting plate 34, so that the sliding process of the cleaning roller 32 along the electrostatic suction cup 31 is more stable.

[0066] like Fig.10 , Fig.11 and Fig.12 As shown, a gear 35 is fixedly connected to the outside of the rotating column 33 , a rack 36 is provided on the outside of the gear 35 , the gear 35 and the rack 36 are meshed, and the rack 36 is fixedly connected to the bottom inner wall of the housing 10 .

[0067] According to the above structure, when the lens assembly 11 drives the rotating column 33 to slide along the bottom of the shell 10, the rotating column 33 drives the gear 35 to move along the rack 36. Since the gear 35 is meshed with the rack 36, the gear 35 rotates while moving. The gear 35 drives the cleaning roller 32 to rotate through the rotating column 33, so that the cleaning roller 32 rolls along the electrostatic suction cup 31, thereby improving the contact efficiency between the outer surface of the cleaning roller 32 and the electrostatic suction cup 31, thereby improving the efficiency of removing impurities.

[0068] like Fig.10 , Fig.11 and Fig.12 As shown, a slider 331 is fixedly connected to the bottom of the rotating column 33, a groove 104 is opened on the bottom inner wall of the shell 10, the groove 104 and the slider 331 are slidably matched, a baffle 332 is provided above the slider 331, and the baffle 332 is fixedly connected to the bottom inner wall of the shell 10.

[0069] It should be noted that the groove 104 is also rotatably matched with the slider 331 , the inner diameter of the baffle 332 is smaller than the diameter of the slider 331 , and the outer diameter of the baffle 332 is larger than the diameter of the slider 331 .

[0070] According to the above structure, the groove 104 cooperates with the slider 331, so that the sliding process of the rotating column 33 along the bottom of the shell 10 is more stable. In this process, the baffle 332 prevents the slider 331 from moving upward, avoiding the situation where the slider 331 is separated from the groove 104, thereby improving the stability of the sliding process of the rotating column 33.

[0071] like Fig.10 , Fig.11 and Fig.12As shown, a sliding hole 321 is formed at the bottom of the cleaning roller 32 , and a sliding column 333 is fixedly connected to the top of the rotating column 33 , and the sliding column 333 and the sliding hole 321 are slidably matched along the vertical direction.

[0072] It should be noted that the cross-sectional shapes of the sliding column 333 and the sliding hole 321 are both triangular or rectangular.

[0073] According to the above structure, the sliding column 333 cooperates with the sliding hole 321 to limit the rotating column 33 and the cleaning roller 32 in the radial direction, so that the cleaning roller 32 can be driven to rotate together when the rotating column 33 rotates, and the cleaning roller 32 and the rotating column 33 are quickly disassembled and assembled.

[0074] like Fig.10 , Fig.11 and Fig.12 As shown, a first slide groove 341 is provided inside the connecting plate 34, and the first slide groove 341 is slidably matched with the top of the cleaning roller 32. A second slide groove 342 is provided at one end of the first slide groove 341 close to the material exchange port 103, and a recessed portion 322 is provided at the upper end of the cleaning roller 32, and the recessed portion 322 is slidably matched with the second slide groove 342.

[0075] It should be noted that the inner diameter of the second slide groove 342 is smaller than the inner diameter of the first slide groove 341 and larger than the diameter of the recessed portion 322. The second slide groove 342 is provided with an opening at one end close to the material changing port 103. A door panel 37 is provided on the outer side of the material changing port 103. The door panel 37 is fixedly mounted on the outer wall of the shell 10 to prevent external dust and other impurities from entering the interior of the shell 10.

[0076] The cleaning roller 32 is then moved to the position where the cleaning roller 32 is to be removed from the cleaning groove 341 and to the position where the cleaning roller 32 is to be removed from the cleaning groove 342. The cleaning roller 32 is inserted into the interior of the housing 10, and the recessed portion 322 slides inwardly along the second slide groove 342, so that the recessed portion 322 moves into the first slide groove 341, and the cleaning roller 32 is moved downward, so that the cleaning roller 32 is connected to the rotating column 33, and the top of the cleaning roller 32 is inserted into the interior of the first slide groove 341, so that the cleaning roller 32 is installed, and the cleaning roller 32 is disassembled and assembled, which is convenient for replacing the cleaning roller 32 or taking out the cleaning roller 32 to clean the impurities attached to the cleaning roller 32, thereby improving the convenience of removing impurities. After the cleaning roller 32 is connected to the rotating column 33, the second slide groove 342 and the recessed portion 322 are staggered from each other in the vertical direction, and the second slide groove 342 prevents the cleaning roller 32 from moving outward through the second slide groove 342, thereby preventing the cleaning roller 32 from being separated from the connecting plate 34 during the process of cleaning the electrostatic suction cup 31.

[0077] The working principle of the present invention is as follows: when it is necessary to adjust the position of the lens assembly 11 and multiple optical components 12 to adjust the size of the light spot, the operator moves the adjustment shaft 231 from the outside of the shell 10, so that the driving part 22 switches to the corresponding adjustment part 21 respectively, and then rotates the driving cylinder 221 to drive the lens assembly 11 and one of the multiple optical components 12 to slide through the corresponding adjustment part 21, thereby adjusting the position of the lens assembly 11 or multiple optical components 12 in the shell 10 to adjust the size of the light spot, avoiding the need to disassemble and assemble the shell 10 during adjustment in the traditional way, and improving the convenience of light spot adjustment. In the process of moving the lens assembly 11, the dust removal mechanism 30 works and absorbs impurities such as dust raised by the lens assembly 11 during movement through the electrostatic suction cup 31, thereby reducing the situation where impurities affect the laser beam quality and improving the reliability of light spot adjustment. At the same time, the lens assembly 11 also drives the cleaning roller 32 to move to remove impurities adsorbed on the electrostatic suction cup 31, thereby extending the service life of the electrostatic suction cup 31.

[0078] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
