Abstract
Description
Technical Field
[0001] This utility model relates to the field of light guide processing technology, specifically to a laser marking device for processing markings on the surface of a light guide. Background Technology
[0002] A light guide is a component that transmits light from one light source to another point a certain distance away with minimal loss. In the automotive industry, light guides are commonly used in various lighting fixtures such as daytime running lights and ambient lights. During the manufacturing process, laser marking equipment is used to create easily distinguishable markings on the surface of the light guide. Since the light guide is generally cylindrical in shape, it needs to be rotated during the marking process to ensure that the surface of the light guide is fully marked.
[0003] For example, Chinese patent document CN117428356A discloses a drill bit laser marking device, including: a worktable; a rotating disk rotatably connected to the worktable; a clamping assembly disposed on the rotating disk; a top plate disposed on the worktable; the clamping assembly includes: a sliding rod slidably connected to a rotating frame; a half gear rotatably connected to the rotating frame; a rotating arm rotatably connected between the half gear and the inner end of the sliding rod; a clamping block slidably connected to the rotating frame; and a rack fixedly connected to the end of the clamping block.
[0004] In the above technical solution, the sliding rod is used to move the clamping blocks closer or further apart to clamp the columnar material. Therefore, when processing the surface of the light guide, the sliding rod needs to be driven repeatedly, which makes it impossible to quickly put the light guide into the surface processing process. This results in the inability to process the light guide in large quantities, affecting the processing efficiency. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a laser marking device for processing markings on the surface of light guides, which can improve the processing efficiency of the surface of light guides.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser marking device for processing markings on the surface of a light guide, comprising a machine base, a connecting platform on the machine base, a laser marking device above the connecting platform, a mounting groove inside the connecting platform, a rolling shaft inside the mounting groove, the rolling shaft being rotatably connected to the inner wall of the connecting platform, multiple rolling shafts being spaced apart from each other, the space between adjacent rolling shafts serving as a placement area for placing the light guide, one end of the rolling shaft extending outside the connecting platform as a connecting end, the connecting end being provided with a driving device, the driving device being used to drive multiple rolling shafts to rotate synchronously, and a detachable support sleeve being provided on the outer periphery of the rolling shaft.
[0007] The present invention is further configured such that: the driving device includes a driving motor, a driving wheel is fixedly mounted on the output end of the driving motor, a driven wheel is fixedly mounted on the outer periphery of the connecting end, and a transmission belt is mounted between the driving wheel and the driven wheel, the transmission belt meshing with the driving wheel and the driven wheel respectively.
[0008] The present invention is further configured such that: the support sleeve includes a first connecting part and a second connecting part, the first connecting part is provided with a first threaded hole that is recessed downward, the second connecting part is provided with a second threaded hole that is through, the second threaded hole can be opposite to the first threaded hole, and the second threaded hole and the first threaded hole are connected by a locking member.
[0009] The present invention is further configured such that: a tensioning wheel is provided on the outer side of the connecting platform, and there are multiple tensioning wheels spaced apart from each other. The tensioning wheels are pressed against the surface of the transmission belt so that the transmission belt and the driven wheel are in full contact.
[0010] The present invention is further configured such that: a connecting groove is provided on the connecting platform, a rotating screw arranged in the vertical direction is rotatably connected in the connecting groove, a connecting seat that can form a threaded engagement with the rotating screw is fitted on the outer periphery of the rotating screw, the tensioning wheel is rotatably connected to the connecting seat, and the connecting seat is adapted to the connecting groove.
[0011] The present invention is further configured such that: an adjusting screw is rotatably connected to the machine base, guide rods are provided on both sides of the adjusting screw, an adjusting seat is fixed at the bottom of the connecting platform, the adjusting seat is provided with an adjusting port and a guide port, the adjusting seat is respectively fitted onto the outer periphery of the adjusting screw and the guide rod through the adjusting port and the guide port, and respectively forms a threaded engagement and a sliding engagement with the adjusting screw and the guide rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] Because multiple rolling shafts are installed, a placement area for the light guide can be formed between adjacent rolling shafts. Therefore, when marking the surface of the light guide is required, the light guide only needs to be placed directly into the placement area, and the laser marking device can then mark the surface of the light guide. When marking the other side of the light guide is required, the rolling shaft is rotated by the drive device. The friction generated by the contact between the light guide and the rolling shaft drives the light guide to rotate, so that the other side of the light guide is aligned with the laser marking device. Therefore, this effectively solves the technical problem in the prior art where the light guide needs to be clamped before it can be rotated when marking the entire surface of the light guide, which makes the overall operation cumbersome. This improves the processing efficiency of the light guide surface. Furthermore, by setting detachable support sleeves on the rolling shafts, different sizes of support sleeves can be replaced to form placement areas of different sizes between adjacent rolling shafts, thus adapting to different sizes of light guides and expanding the overall applicability.

[0019] like Figures 1 to 3As shown, this utility model discloses a laser marking device for processing markings on the surface of a light guide. It includes a machine base 1, a connecting platform 2 on the machine base 1, a laser marking device 12 above the connecting platform 2, a mounting groove inside the connecting platform 2, and a rolling shaft 3 inside the mounting groove. The rolling shaft 3 is rotatably connected to the inner wall of the connecting platform 2. Multiple rolling shafts 3 are spaced apart from each other, with the space between adjacent rolling shafts 3 serving as a placement area for the light guide. One end of each rolling shaft 3 extends outside the connecting platform 2 as a connecting end 31, which is equipped with a driving device for driving the multiple rolling shafts 3 to rotate synchronously. A detachable support sleeve 4 is provided around the outer periphery of each rolling shaft 3. Because multiple rolling shafts 3 are provided, a placement area for the light guide can be formed between adjacent rolling shafts 3. Therefore, when it is necessary to process markings on the surface of the light guide... When marking the surface, the light guide body only needs to be placed directly into the placement area, and the laser marking device 12 can mark the surface of the light guide body. When marking the other side of the light guide body is required, the rolling shaft 3 is driven to rotate by the drive device. The friction generated by the contact between the light guide body and the rolling shaft 3 drives the light guide body to rotate, so that the other side of the light guide body can face the laser marking device 12, thereby improving the processing efficiency of the light guide body surface. Furthermore, by setting a detachable support sleeve 4 on the rolling shaft 3, different sizes of placement areas can be formed between adjacent rolling shafts 3 by replacing different sizes of support sleeves 4, thereby adapting to different sizes of light guide bodies and expanding the overall applicability. The laser marking device 12 can adopt the existing structure.
[0020] In this embodiment, the specific structure of the driving device includes a drive motor 51, a drive wheel 52 is fixedly mounted on the output end of the drive motor 51, a driven wheel 53 is fixedly mounted on the outer periphery of the connecting end 31, and a transmission belt 54 is mounted between the drive wheel 52 and the driven wheel 53. The transmission belt 54 meshes with the drive wheel 52 and the driven wheel 53 respectively. By driving the drive wheel 52 to rotate through the drive motor 51, the driven wheel 53 on each connecting end 31 can be driven to rotate through the transmission belt 54, thus driving each rolling shaft 3 to rotate.
[0021] In this embodiment, the specific structure of the support sleeve 4 includes a first connecting part 41 and a second connecting part 42. The first connecting part 41 is provided with a downwardly recessed first threaded hole, and the second connecting part 42 is provided with a through second threaded hole 421. The second threaded hole 421 can be opposite to the first threaded hole. The second threaded hole 421 and the first threaded hole are connected by a locking member. By fitting the first connecting part 41 and the second connecting part 42 onto the rolling shaft 3 respectively, and making the first threaded hole and the second threaded hole 421 opposite to each other, a locking member that can form a threaded engagement with the first threaded hole and the second threaded hole 421 can be screwed in or out, thereby realizing a detachable connection between the support sleeve 4 and the rolling shaft 3.
[0022] In this embodiment, tensioning wheels 6 are further provided on the outer side of the connecting platform 2. There are multiple tensioning wheels 6, which are spaced apart from each other. The tensioning wheels 6 press against the surface of the transmission belt 54 so that the transmission belt 54 and the driven wheel 53 can fully contact each other. By setting the tensioning wheels 6, the transmission belt 54 can be pressed down, so that the transmission belt 54 can fully contact the driven wheel 53, thereby facilitating the drive motor 51 to drive each driven wheel 53 to rotate stably.
[0023] In this embodiment, a connecting groove 21 is further provided on the connecting platform 2. A rotating screw 7 arranged in the vertical direction is rotatably connected in the connecting groove 21. A connecting seat 8 that can form a threaded engagement with the rotating screw 7 is fitted on the outer periphery of the rotating screw 7. The tensioning wheel 6 is rotatably connected to the connecting seat 8. The connecting seat 8 is adapted to the connecting groove 21. By setting the rotating screw 7, the rotating screw 7 can be driven to rotate, so that the connecting seat 8 fitted on the outer periphery of the rotating screw 7 and forming a threaded engagement can move along the direction of the rotating screw 7 under the guiding action of the mutually adapted connecting groove 21. This allows the tensioning wheel 6 to adjust the squeezing force of the transmission belt 54 to adapt to more usage scenarios.
[0024] In this embodiment, an adjusting screw 9 is further rotatably connected to the machine base 1. Guide rods 10 are provided on both sides of the adjusting screw 9. An adjusting seat 11 is fixed at the bottom of the connecting platform 2. The adjusting seat 11 is provided with an adjusting port and a guiding port. The adjusting seat 11 is respectively fitted around the outer periphery of the adjusting screw 9 and the guiding rod 10 through the adjusting port and the guiding port, and forms a threaded engagement and a sliding engagement with the adjusting screw 9 and the guiding rod 10, respectively. The adjusting screw 9 is driven to rotate by a corresponding motor, so that the adjusting seat 11, which is fitted around the outer periphery of the adjusting screw 9 and forms a threaded engagement with the adjusting screw 9 through the adjusting port, can move along the direction of the adjusting screw 9 under the guidance of the guiding port and the guiding rod 10. In this way, the connecting platform 2 can be fed towards the laser marking device 12, so that the light guides in each placement area can be opposite to the laser marking device 12, thus realizing the surface processing of multiple light guides.
[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
