Description

Technical Field

[0001] The invention relates to the technical field of laser cleaning, in particular to a collimator sheath for multi-posture laser cleaning. Background Art

[0002] Industrial cleaning refers to the cleaning process involved in the industrial production labor process and is closely related to various industrial activities. Although industrial cleaning does not provide the final product, it is one of the key and indispensable links in the industrial production process.

At present, the cleaning industry has penetrated into almost all industrial fields, especially in the high-tech industry, where the role of intelligent multi-posture cleaning of complex workpiece surfaces is particularly prominent.

[0003] Cleaning of attachments on the surface of workpieces is a necessary step in industrial production and has extremely wide demand. Traditional cleaning processes rely heavily on chemical reagents or mechanical polishing. Against this background, various green cleaning technologies have emerged, and laser cleaning technology is one of them. Laser cleaning can be equipped with actuators such as robotic arms and linear modules to perform comprehensive cleaning of objects to be cleaned on the surface of complex workpieces from multiple angles.

[0004] For example, a tire mold laser cleaning device with Chinese utility model publication number CN213353196U discloses that laser light enters a collimator through an optical fiber to form parallel light, which is then reflected onto a first reflector, then onto a second reflector, and then onto a galvanometer mirror. The light is then transmitted to a plano-convex lens through the swing of the galvanometer mirror to converge to a focal point, and then is emitted onto the mold through a window protective mirror. Compressed gas is blown onto the mold cleaning surface through the air duct of the blowing nozzle.

[0042] See also Figure 1-Figure 2 A collimator sheath for multi-posture laser cleaning includes a fixing seat 1, the sheath is installed and fixed as a whole through the fixing seat 1, and a support ring 2 is connected to one side of the fixing seat 1, the support ring 2 is sleeved on the outer wall of the collimator, and a functional segment 3 is integrally formed at the other end of the support ring 2. Considering the accuracy and stability of the collimator, a slot 5 is opened through the surface of the functional segment 3 to avoid interference of the functional segment 3 with the collimator and improve the practicality of the sheath. In addition, considering the overall installation stability of the sheath, a fastening lip 4 is connected to the outside of the functional segment 3, and the fastening lip 4 and the functional segment 3 are integrally formed, and the fastening lip 4 is opened equidistantly on one side of the functional segment 3, and in order to achieve the adjustment effect and adjustment range of the fastening lip 4 , a gap is provided between the fastening lips 4, which is convenient for the user to adjust the tightness of the fastening lips 4 through the gap distance. The fastening lips 4 are fixed and the tightness is adjusted by the clamp 12 during installation, ensuring the installation stability of the fastening lips 4 on the outer wall of the collimator. By fixing the fixing seat 1 and the fastening lips 4 at both ends of the sheath as a whole, the sheath has a good protective effect on the outside of the collimator, avoiding the torque between the collimator and the optical fiber, effectively preventing the collimator from loosening, and ensuring the working quality of the collimator. In order to improve the limiting effect of the fastening lip 4 on the clamp 12 on one side, a folded edge is provided at one end of the fastening lip 4, ensuring the connection stability of the fastening lip 4 and the clamp 12, which is beneficial to extending the overall service life and working quality of the sheath.

[0043] Example 2

[0044] The difference between this embodiment and embodiment 1 is that:

[0045] See also Figure 3 , the fixing seat 1 adopts a polygonal structure, and the support ring 2 and the functional section 3 both adopt a rectangular structure, and the fastening lip 4 is arranged on one side of the functional section 3 corresponding to the rectangle;

[0046] Through such an arrangement, the sheath can adopt different shapes according to different needs, and is highly practical and widely applicable. Moreover, through the corresponding arrangement between the support ring 2 and the functional segment 3, the sheath can be installed and used for collimators of different specifications, thereby expanding the scope of application of the sheath and improving the flexibility of the sheath.

[0047] Example 3

[0048] The difference between this embodiment and embodiment 1 is that:

[0049] See also Figure 4-Figure 7 Considering the installation and use of collimators of different specifications, a size adjustment structure is provided inside the support ring 2. The size adjustment structure includes a telescopic spring 601, and the telescopic spring 601 is fixedly installed on the inner wall of the support ring 2. The other end of the telescopic spring 601 is connected to a connecting plate 602. The cross-section of the connecting plate 602 is an L-shaped structure. The side wall of the connecting plate 602 is fixedly connected to the bottom end of the telescopic spring 601, so that the connecting plate 602 can be adjusted at a distance from the inner wall of the support ring 2 under the elastic action of the telescopic spring 601. Adjustment: Three groups of adjusting rollers 604 are connected to the interior of the connecting plate 602 through a rotating shaft 603. The adjusting rollers 604 form a rotating structure between the rotating shaft 603 and the connecting plate 602, which facilitates the multiple groups of adjusting rollers 604 to rotate separately inside the support ring 2. In addition, considering the fitting effect between the adjusting rollers 604 and the outer wall of the collimator, the adjusting rollers 604 are set in a drum-shaped structure, that is, the diameters at both ends are smaller than the diameter in the middle, which facilitates the fitting and limiting of the middle part of the adjusting rollers 604 and the collimator, which is conducive to adjusting collimators of different sizes.

[0050] Taking into account the tightening effect of one end of the fastening lip 4 when the sheath is fitted on the outer wall of the collimator, in order to achieve synchronous fixation of the clamp 12, a transmission rod 8 is provided through the interior of the support ring 2, and a support spring 9 is provided on the outer wall of the transmission rod 8. At the same time, the transmission rod 8 and the support spring 9 are both provided between the adjusting roller 604 and the inner wall of the support ring 2, and the top of the transmission rod 8 is fitted with the outer wall of the adjusting roller 604. When the adjusting roller 604 is fitted on the outer wall of the collimator and moves toward the inner wall of the support ring 2, the support spring 9 is squeezed, so that the transmission rod 8 is The interior of the support ring 2 extends outward, and a rack 10 is wedge-shapedly connected to the bottom end of the transmission rod 8. Under the action of a gear 11 meshed with the bottom end of one side of the rack 10, the rack 10 drives the gear 11 to rotate when it is squeezed. The gear 11 is provided on one side of the clamp 12, so that the clamp 12 can be adjusted arbitrarily through the gear 11 and the adjusting screw head 13 on the other side. By rotating the gear 11, the clamp 12 can be adjusted through the rack 10 when the transmission rod 8 is squeezed, thereby achieving the effect of tightening the clamp 12 when the sheath is in contact with the outer wall of the collimator.

[0051] Taking into account the movement stability of the rack 10, a slider 14 is fixedly installed at the bottom end of the rack 10, and the bottom end of the slider 14 is slidably connected to a slide groove 15, and the slide groove 15 is opened on the inner wall of the external plate 7, so that the rack 10 can move accurately on the inner wall of the external plate 7 through the slide groove 15 and the slider 14, and the external plate 7 is fixedly connected to the outer wall of the support ring 2 and is arranged below the transmission rod 8, so that the transmission rod 8 and the rack 10 can achieve accurate transmission inside the external plate 7, ensuring the stability of the device. At the same time, considering the movement limiting effect of the rack 10, a return spring 16 is provided between the slider 14 and the external plate 7, and one side of the return spring 16 is fixedly installed to the inner wall of the external plate 7;

[0052] Through such an arrangement, when the support ring 2 is sleeved and installed on the outer wall of collimators of different specifications, the connecting plate 602 can drive the adjusting roller 604 to fit and limit the outer wall of the collimator under the elastic action of the telescopic spring 601, and the rotation setting of the adjusting roller 604 allows the user to rotate the support ring 2 and the sheath as a whole through the adjusting roller 604, which facilitates the adjustment of the position of the functional section 3 and the slot 5, thereby ensuring the working quality and working effect of the sheath;

[0053] At the same time, by arranging a transmission rod 8 on the outer wall of the adjusting roller 604, the rack 10 can realize transmission under the wedge action of the transmission rod 8 and the rack 10, and through the meshing connection between the rack 10 and the gear 11, the rack 10 can adjust the tightness of the clamp 12 through the gear 11, so that the sheath can synchronously adjust the clamp 12 when the collimator is installed, and by arranging an adjustment screw head 13 on the other side of the clamp 12, the user can flexibly adjust the clamp 12 through the adjustment screw head 13, thereby improving the practicality and flexibility of the clamp 12.

[0054] Example 4

[0055] The difference between this embodiment and embodiment 3 is that:

[0056] See also Figure 8 The interior of the size adjustment structure includes a connecting block 605, which is integrally formed on the inner wall of the support ring 2, and a splint 606 is integrally formed on the bottom end of the connecting block 605, and multiple groups of splints 606 are equidistantly arranged in an annular shape inside the support ring 2, and the gaps between each group of splints 606 are the same, and considering the limiting and fitting effect of the splint 606 on the outer wall of the collimator inside the support ring 2, while avoiding damage to the outer wall of the collimator by the splint 606, the splint 606 is arranged in an arc shape, and both ends of the splint 606 are provided with upward warped edges, which facilitates the insertion of the collimator inside the splint 606, thereby achieving a stable sleeve of the support ring 2 on the collimator through the splint 606;

[0057] Through such an arrangement, the support ring 2 can limit the outer wall of the collimator through the clamping plates 606 and the warped edges on both sides. Since the clamping plates 606 have a certain length and elasticity, the clamping plates 606 arranged equidistantly in an annular shape can clamp and limit collimators of different diameters, making it easier for the sheath to be used with collimators of different specifications, thereby improving the practicality of the sheath.

[0058] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
