Description

Technical Field

[0001] This application relates to the technical field of laser engraving equipment, and in particular to a laser engraving device and automotive turn signals produced using the laser engraving device. Background Technology

[0002] Vehicle turn signals are safety signal devices on motor vehicles used to indicate the intention to turn or change lanes. They use flashing yellow light to warn surrounding vehicles and pedestrians to prevent collisions. Vehicle turn signals consist of a base, a circuit board, and an outer cover. In the actual manufacturing process, the circuit board is first installed on the base, and then the outer cover is welded to the base by vibration friction. Finally, it is tempered to relieve stress and then airtightened before lighting.

[0003] The aforementioned traditional automotive turn signals emit light as a whole when illuminated. In practical applications, laser engraving equipment is usually used to add laser engraving technology to the outer cover to optimize light distribution and prevent glare. Therefore, there is an urgent need for a laser engraving equipment that can be used to add laser engraving technology to the outer cover. Summary of the Invention

[0004] In order to add laser engraving to the outer cover of automotive turn signals to optimize light distribution and reduce glare, this application provides a laser engraving device and an automotive turn signal produced using the laser engraving device.

[0005] Firstly, this application provides a laser engraving device, which adopts the following technical solution: A laser engraving device for forming laser engravings on the outer cover of automotive turn signals includes a frame, on which are provided a laser engraving mechanism for performing laser engraving on the outer cover and a clamping assembly for holding the outer cover. A support block is slidably connected to the frame, and the clamping assembly is oscillatingly mounted on the support block. The frame is provided with a sliding assembly for controlling the sliding of the support block and an oscillating assembly for controlling the oscillation of the clamping assembly. The sliding assembly includes a laser engraving area and a loading / unloading area, and the laser engraving mechanism corresponds to the laser engraving area.

[0006] By adopting the above technical solution, the outer cover to be laser-engraved is placed after the clamping component. The outer cover is moved to the laser engraving area by the sliding component. The laser engraving mechanism then performs laser engraving on the outer cover. During this process, the outer cover can be swung relative to the laser engraving mechanism by the swing component to complete the laser engraving. This allows the vehicle turn signal to achieve the effects of optimizing light distribution and preventing glare.

[0007] Preferably, the swing assembly includes a drive worm wheel and a drive worm that mesh with each other. The drive worm wheel and the drive worm are both rotatably disposed within the support block. A swing shaft is coaxially provided on the drive worm wheel. Swing plates are provided at both ends of the swing shaft. The end of the swing plate away from the swing shaft is connected to the clamping assembly. The frame is provided with a placement block for supporting the control block. The control block is slidably connected to the placement block and slides perpendicular to the sliding direction of the support block. The placement block is provided with a control component for controlling the sliding of the control block. The control block is provided with a drive motor. A linkage rod is coaxially provided on the output shaft of the drive motor. A control rod corresponding to the linkage rod is rotatably connected to the support block. The control rod is provided with a first bevel gear. A second bevel gear meshing with the first bevel gear is coaxially provided on the drive worm gear. The control rod is provided with a control groove for the linkage rod to be inserted after sliding.

[0008] By adopting the above technical solution, after the control block slides, the linkage rod on the drive motor is embedded in the control groove of the control rod. After the drive motor is started, the rotation of the control rod can drive the drive worm gear to rotate, thereby driving the clamping assembly connected to the swing plate to rotate synchronously through the rotation of the drive worm gear.

[0009] Preferably, the frame is provided with a protective cover, the protective cover has a clearance groove for the sliding of the support block, both ends of the protective cover are provided with protective plates, the protective plates are rotatably mounted on the placement block, and the placement block is provided with a rotating component for controlling the rotation of the protective plates.

[0010] By adopting the above technical solution, the protective plate and the protective cover work together to provide a smaller operating space, reduce the leakage of dust during the laser engraving process, and ensure the cleanliness of the workshop; the rotating design of the protective plate makes it less likely to interfere with the normal sliding of the support block, thus ensuring the normal use of the equipment.

[0011] Preferably, the rotating component includes a rotating gear and a rotating rack that mesh with each other. The rotating gear is rotatably mounted on the placement block, and the rotating rack is mounted on the control block. A protective shaft is coaxially mounted on the rotating gear, and the end of the protective shaft is connected to a protective plate. The protective plate rotates about the protective shaft as its axis of rotation.

[0012] By adopting the above technical solution, during the sliding process of the control block, the rotating rack can drive the rotating gear to rotate, so that the protective plates located on both sides of the control block can rotate with the rotation of the rotating gear. No additional drive source is required, and it is easy to control the rotation time of the protective plates, effectively preventing the possibility of misoperation.

[0013] Preferably, the control block is provided with a limiting rod, and the support block is provided with a limiting groove that cooperates with the limiting rod, wherein the limiting rod is longer than the control rod.

[0014] By adopting the above technical solution, the cooperation between the limiting rod and the limiting groove provides initial positioning for the sliding of the linkage rod toward the control groove, improves the accuracy of the sliding of the linkage rod toward the control groove, and ensures the service life of the equipment to a certain extent.

[0015] Preferably, a plurality of ball bearings are rotatably connected to the support block, and the ball bearings are in contact with the end face of the placement block.

[0016] By adopting the above technical solution, the ball bearings can provide support and positioning for the support block to a certain extent, making it less likely for the support block to collide with the inner wall of the relief groove when it slides into the relief groove.

[0017] Preferably, the placement block is provided with a positioning slide rail, and the control block is provided with a positioning slider that cooperates with the positioning slide rail.

[0018] By adopting the above technical solution, the positioning slider and the positioning slide rail work together to ensure the stability and smoothness of the control block sliding.

[0019] Preferably, the clamping assembly includes a clamping plate connected to a swing plate. A fixed clamping block and a movable clamping block are provided at the end of the clamping plate opposite to the supporting block. The fixed clamping block and the movable clamping block cooperate to clamp the outer cover. The movable clamping block is slidably disposed on the clamping plate. The clamping plate is provided with a clamping groove for sliding the movable clamping block. The clamping plate is provided with a sliding member for controlling the sliding of the movable clamping block. The fixed clamping block, the clamping plate, and the movable clamping block are all provided with friction-increasing protective pads that contact the outer cover.

[0020] By adopting the above technical solution, the sliding component controls the sliding of the moving clamping block, so that the moving clamping block can cooperate with the fixed clamping block to clamp the outer cover, which is convenient for operation. The setting of the friction-increasing protective pad makes it difficult for the outer cover to move relative to the clamping component during the swinging process of the clamping component, and the setting of the friction-increasing protective pad makes the outer cover less likely to be damaged during the clamping process.

[0021] Preferably, the friction-enhancing protective pad is provided with a fitting groove for fitting the outer cover.

[0022] By adopting the above technical solution and setting the fitting groove, the position of the outer cover can be initially positioned during the process of installing the outer cover into the clamping component, ensuring the accuracy and aesthetics of the laser engraving.

[0023] In a first aspect, this application provides a vehicle turn signal produced using the aforementioned laser engraving equipment, employing the following technical solution: Preferably, the device includes a base, a circuit board, an inner cover, and an outer cover arranged in sequence. The circuit board and the inner cover are mounted on the base by hot riveting welding, and the outer cover is mounted on the base by vibration friction welding. The outer cover is painted and has laser engraving corresponding to the circuit board.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. After placing the outer cover to be laser-engraved on the clamping assembly, the outer cover is moved to the laser engraving area by the sliding assembly. The laser engraving mechanism then performs laser engraving on the outer cover. During this process, the outer cover can be swung relative to the laser engraving mechanism by the swinging assembly to complete the laser engraving. This allows the vehicle turn signal to achieve optimized light distribution and anti-glare effects. The improvement in this application enables the laser engraving equipment to be adapted to the needs of laser engraving on the outer cover. 2. After the control block slides, the linkage rod on the drive motor is embedded in the control slot of the control rod. After the drive motor is started, the rotation of the control rod can drive the drive worm gear to rotate, which in turn drives the clamping assembly connected to the swing plate to rotate synchronously through the rotation of the drive worm gear. During the sliding process of the control block, the rotating rack can drive the rotating gear to rotate, so that the protective plates located on both sides of the control block can rotate with the rotation of the rotating gear. No additional drive source is required, and it is easy to control the rotation time of the protective plates, effectively preventing the possibility of misoperation. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0035] This application discloses a laser engraving device for forming laser engravings on the outer cover 84 of a vehicle turn signal 8. (Refer to...) Figure 1 , Figure 2 and Figure 3 The system includes a frame 1, on which a laser engraving mechanism 11 for laser engraving on an outer cover 84 and a clamping assembly 12 for clamping the outer cover 84 are mounted. A support block 6 is slidably connected to the frame 1. The clamping assembly 12 is oscillatingly mounted on the support block 6. Since the outer cover 84 of the vehicle turn signal 8 is mostly arc-shaped, the angle of the outer cover 84 relative to the laser engraving mechanism 11 can be adjusted by the oscillation of the clamping assembly 12 during the laser engraving process, thereby successfully completing the laser engraving process.

[0036] Reference Figure 3The frame 1 is equipped with a sliding assembly 2 for controlling the sliding of the support block 6. The sliding assembly 2 includes a laser engraving area 21 and a loading / unloading area 22. The laser engraving mechanism 11 corresponds to the laser engraving area 21. The sliding assembly 2 only needs to be able to drive the support block 6 to slide in a straight line. Suitable sliding assemblies 2 can be purchased according to the actual situation of each workshop. In this embodiment, the sliding assembly 2 is a linear guide rail. The linear guide rail includes a guide rail part 23 and two drive sliders slidably disposed on the guide rail part 23. The support block 6 can be fixed to the drive sliders by bolts or welding. There are two loading / unloading areas 22, which are symmetrically arranged on both sides of the laser engraving area 21. When one drive slider is located in the laser engraving area 21 and corresponds to the laser engraving mechanism 11, the other drive slider is located in the loading / unloading area 22. During the laser engraving of an outer cover 84, the laser-engraved outer cover 84 can be removed and a new outer cover 84 can be installed.

[0037] Reference Figure 4 and Figure 5 The clamping assembly 12 includes a clamping plate 121. A fixed clamping block 122 and a movable clamping block 123 are provided at the end of the clamping plate 121 opposite to the supporting block 6. The fixed clamping block 122 and the movable clamping block 123 cooperate to clamp the outer cover 84. The movable clamping block 123 is slidably disposed on the clamping plate 121. The clamping plate 121 is provided with a clamping groove 124 for sliding the movable clamping block 123, and the clamping plate 121 is also provided with a groove for controlling the sliding of the movable clamping block 123. The sliding component includes an adjusting bolt 125 rotatably mounted on the clamping support plate 121. The clamping support plate 121 has a rotating hole for the threaded portion of the adjusting bolt 125 to pass through and rotate. The rotating hole communicates with the clamping groove 124. The movable clamping block 123 has an adjusting threaded hole 126 that engages with the threaded portion of the adjusting bolt 125. When the adjusting bolt 125 rotates, the movable clamping block 123 can slide along the clamping groove 124 under the action of threaded transmission. The fixed clamping block 122, the clamping support plate 121, and the movable clamping block 123 are all provided with friction-increasing protective pads 127 that contact the outer cover 84. The friction-increasing protective pads 127 need to have a certain degree of flexibility so that the outer cover 84 is not easily damaged during clamping. During the clamping of the outer cover 84, the clamping force can be controlled by the sliding of the movable clamping block 123.

[0038] Reference Figure 3 The friction-enhancing protective pad 127 is provided with a fitting groove 128 for the outer cover 84 to fit into. By setting the fitting groove 128, the position of the outer cover 84 can be initially positioned during the process of installing the outer cover 84 into the clamping assembly 12, ensuring the accuracy and aesthetics of the laser engraving. The friction-enhancing protective pad 127 can be combined with the fixed clamping block 122 and the movable clamping block 123 by adhesive or Velcro. In the actual production process, the appropriate friction-enhancing protective pad 127 can be installed according to the size of the outer cover 84, which improves the applicability to a certain extent.

[0039] Reference Figure 4 and Figure 5 The frame 1 is provided with a swing assembly 3 for controlling the swing of the clamping assembly 12. The swing assembly 3 includes a drive worm gear 31 and a drive worm 32 that mesh with each other. Both the drive worm gear 31 and the drive worm 32 are rotatably mounted in the support block 6. A swing shaft 311 is coaxially mounted on the drive worm gear 31. The swing shaft 311 is fixedly connected to the drive worm gear 31 by a spline. Swing plates 312 are fixedly mounted at both ends of the swing shaft 311. The end of the swing plate 312 away from the swing shaft 311 is fixedly connected to the side wall of the clamping plate 121. When the drive worm 32 rotates, the drive worm gear 31 can drive the clamping plate 121 to rotate synchronously through the swing shaft 311, thereby completing the laser engraving process on the outer cover 84.

[0040] Reference Figure 3 and Figure 6 The frame 1 is provided with a placement block 4 for supporting the control block 5. The control block 5 is slidably connected to the placement block 4. The control block 5 slides perpendicular to the sliding direction of the support block 6. Two positioning slide rails 51 are fixed on the placement block 4. The two positioning slide rails 51 are symmetrically arranged on both sides of the center line of the control block 5. The control block 5 is provided with a positioning slider 511 that cooperates with the positioning slide rail 51. The positioning slider 511 cooperates with the positioning slide rail 51 to ensure the stability and smoothness of the sliding of the control block 5. The placement block 4 is provided with a control component for controlling the sliding of the control block 5. In this embodiment, the control component is a control cylinder 52. The body of the control cylinder 52 is fixed to the placement block 4, and the output shaft of the control cylinder 52 is fixed to the control block 5.

[0041] Reference Figure 3 and Figure 4 The control block 5 is equipped with a drive motor 53, which can be fixed to the control block 5 with bolts. The output shaft of the drive motor 53 is coaxially equipped with a linkage rod 531. The support block 6 is rotatably connected with a control rod 61 corresponding to the linkage rod 531. The control rod 61 is equipped with a first bevel gear 611. The drive worm gear 32 is coaxially equipped with a second bevel gear 321 that meshes with the first bevel gear 611. The control rod 61 is equipped with a control groove 612 for the linkage rod 531 to slide and embed. The end of the linkage rod 531 away from the drive motor 53 is equipped with a linkage inclined surface that provides guidance.

[0042] Reference Figure 1 and Figure 2 A protective cover 7 is fixed on the frame 1, and protective plates 72 are provided at both ends of the protective cover 7. Figure 1To better showcase the protective cover 7, a protective plate 72 is concealed. The protective plate 72 works in conjunction with the protective cover 7 to provide a smaller operating space, reducing dust leakage during laser engraving and ensuring the cleanliness of the workshop. The protective cover 7 is provided with a clearance groove 71 for the sliding of the support block 6. The clearance groove 71 is set along the sliding direction of the support block 6. When the support block 6 slides to the laser engraving area 21, the support block 6 is located in the operating space formed by the cooperation of the protective plate 72 and the protective cover 7, and part of the support block 6 extends out of the operating space through the clearance groove 71. The portion of the support block 6 extending out of the clearance groove 71 in the laser engraving area coincides vertically with the placement block 4. Multiple ball bearings 62 are rotatably connected to the support block 6. As the support block 6 slides from the loading / unloading area 22 toward the laser engraving area 21, the ball bearings 62 sequentially slide to contact the end face of the placement block 4. The number of ball bearings 62 depends on the size of the support block 6, and they are arranged along the sliding direction of the support block 6. The ball bearings 62 provide support and positioning for the support block 6 to a certain extent, preventing the support block 6 from colliding with the inner wall of the clearance groove 71 when it slides into it.

[0043] Reference Figure 2 and Figure 6 The protective plate 72 is rotatably mounted on the placement block 4. This rotatable design prevents interference with the normal sliding of the supporting block 6, ensuring the proper functioning of the equipment. The placement block 4 is equipped with a rotating component for controlling the rotation of the protective plate 72. This component includes a meshing rotating gear 41 and a rotating rack 54. The rotating gear 41 is rotatably mounted on the placement block 4, and the rotating rack 54 is mounted on the control block 5. A protective shaft 411 is coaxially mounted on the rotating gear 41, with its end connected to the protective plate 72. As the protective plate 72 rotates around the protective shaft 411, the rotating rack 54 drives the rotating gear 41 to rotate during the sliding of the control block 5. This allows the protective plates 72 located on both sides of the control block 5 to rotate in tandem with the rotating gear 41, eliminating the need for an additional drive source and facilitating control of the rotation time of the protective plate 72, effectively preventing potential misoperation.

[0044] Reference Figure 3 The control block 5 is equipped with a limiting rod 55, and the support block 6 is equipped with a limiting groove that cooperates with the limiting rod 55. The limiting rod 55 is longer than the control rod 61, and the end of the limiting rod 55 is equipped with a limiting inclined surface for guidance. In actual application, the control block 5 first slides until the limiting rod 55 is embedded in the limiting groove. Then, as the control block 5 slides, the linkage rod 531 slides into the control groove 612 embedded in the control rod 61. The cooperation between the limiting rod 55 and the limiting groove provides initial positioning for the sliding of the linkage rod 531 toward the control groove 612, improves the accuracy of the sliding of the linkage rod 531 toward the control groove 612, and to a certain extent ensures the service life of the equipment.

[0045] The implementation principle of a laser engraving device in this application embodiment is as follows: The laser engraving device provided with a frame 1 and a laser engraving mechanism 11 in this application can be obtained directly through procurement. Then, a linear guide rail is installed on the frame 1, and the support block 6 with a clamping component 12 is fixed on the drive slider of the linear guide rail. Finally, the placement block 4 with a control block 5 is installed at the corresponding position.

[0046] In actual use, the outer cover 84 is first placed in the fitting groove 128 in the loading and unloading area 22. Then, the adjusting bolt 125 is rotated to control the sliding clamp 123 to cooperate with the fixed clamp 122 to clamp the outer cover 84. Then, the linear guide rail is started so that the outer cover 84 to be laser engraved slides to the laser engraving area 21. At this time, loading can be performed in the loading and unloading area 22 on the other side.

[0047] Then, the control cylinder 52 is activated to drive the control block 5 to slide. The control block 5 first slides to the limit rod 55 and is embedded in the limit groove to initially position the support block 6. Then, the control block 5 can slide to the linkage rod 531 and be embedded in the control groove 612. During this process, the protective plate 72 can rotate to the designated position with the cooperation of the rotating gear 41 and the rotating rack 54. The drive motor 53 is activated, and the swing assembly 3 drives the clamping assembly 12 to swing the outer cover 84 during the laser engraving process.

[0048] This application embodiment also provides a vehicle turn signal 8 manufactured using the aforementioned laser engraving equipment, see reference. Figure 6 and Figure 7 The assembly includes a base 81, a circuit board 82, an inner cover 83, and an outer cover 84 arranged sequentially. The circuit board 82 and the inner cover 83 are mounted on the base 81 by hot riveting welding, and the outer cover 84 is mounted on the base 81 by vibration friction welding. The outer cover 84 has a paint spraying area and a laser engraving part 841 corresponding to the circuit board 82. In the actual production process, the outer cover 84 is first painted, and then laser engraving is performed on the painted outer cover 84 using a laser engraving machine. After completion, the circuit board 82, the inner cover 83, and the outer cover 84 are installed on the base 81 in sequence according to the above steps to complete the assembly of the vehicle turn signal 8.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
