Description

Technical Field

[0001] This application relates to the technical field of laser mounting, and in particular to a laser collimation structure. Background Technology

[0002] Currently, as a core component of precision optical systems, the collimation of the output beam of lasers directly affects the performance of downstream optical equipment. Lasers are widely used in laser marking, laser scanning, and laser ranging, as well as in cutting metals.

[0003] In existing technologies, the laser is fixed on the equipment. When it is replaced, it often needs to be calibrated. The calibration method is to adjust the laser by adjusting the screw. When adjusting the screw on one side, the screw on the other side needs to be loosened. When loosening, the laser is prone to movement, which is not convenient for subsequent calibration and adjustment, resulting in wasted time and reduced work efficiency. Summary of the Invention

[0004] To improve the working efficiency of laser collimation, this application provides a laser collimation structure.

[0005] This application provides a laser collimation structure, which adopts the following technical solution:

[0006] A laser collimation structure, comprising:

[0007] The mounting bracket has an internal mounting cavity for mounting the laser.

[0008] Multiple suspended airbags are provided and are all disposed in the mounting cavity. The multiple suspended airbags form a fixed space. The laser is located in the fixed space. Each suspended airbag has at least one through hole, and the through hole is isolated from the air cavity of the suspended airbag.

[0009] Multiple adjusting screws are provided, threadedly connected to the mounting bracket, and the adjusting screws correspond to the through holes and pass through the through holes to abut against the side wall of the laser.

[0010] By adopting the above technical solution, when collimating the laser, the position of the laser is adjusted by rotating the adjusting screw according to the existing position of the laser. During the adjustment process, the suspended airbag limits the laser and reduces the laser's shaking. Moreover, the airbag is elastic and does not affect the adjustment of the laser position by the adjusting screw. At the same time, it can make the laser move smoothly, reduce ineffective adjustments, and thus improve work efficiency.

[0011] Optionally, it also includes:

[0012] An indicator ring is rotatably connected to the mounting bracket and has a sliding hole. The sliding hole is parallel to the axis of the adjusting screw, and the head of the adjusting screw is slidably connected to the sliding hole.

[0013] A graduated ring is mounted on the mounting bracket and sleeved on the indicator ring, allowing relative rotation with the indicator ring;

[0014] A pointer, located on the indicator ring, is capable of rotating along the scale ring.

[0015] By adopting the above technical solution, the laser is installed in a fixed space formed by the suspension airbag. The adjusting screw is screwed into the mounting bracket and passes through the through hole of the suspension airbag to abut against the side wall of the laser. The indicator ring is rotatably connected to the mounting bracket to ensure that the sliding hole is parallel to the axis of the adjusting screw. The head of the adjusting screw is inserted into the sliding hole to achieve sliding connection. The scale ring is sleeved on the indicator ring to ensure that the two can rotate relative to each other. The pointer is fixed to the indicator ring and points to an initial position on the scale ring.

[0016] By observing the relative positions of the scale ring and the pointer, the operator can initially determine the approximate position of the laser. To adjust the laser's position as needed, the operator rotates the adjusting screw. Due to the sliding connection between the adjusting screw and the sliding hole, the screw can move along its axis, thereby pushing the sidewall of the laser and achieving fine-tuning of its position. During the adjustment process, the indicator ring rotates relative to the scale ring as the adjusting screw rotates, and the pointer moves accordingly, indicating the laser's new position in real time. Once the laser's position is adjusted to the correct position, the operator can precisely confirm the laser's final position by observing the pointer's position on the scale ring.

[0017] If necessary, an additional locking device (such as a lock nut) can be used to lock the adjusting screw in its current position to prevent accidental changes in the laser's position.

[0018] By combining the scale ring and pointer, operators can more intuitively understand the current position of the laser and the direction and magnitude of the required adjustment, thereby improving the accuracy of the adjustment.

[0019] The relative rotation design of the indicator ring and the scale ring, as well as the sliding connection between the adjusting screw and the sliding hole, make it easier for operators to adjust the position of the laser without frequently disassembling or moving other parts.

[0020] Because the adjustment process is more intuitive and convenient, operators can complete the laser collimation work more quickly, thereby improving work efficiency.

[0021] The design of the suspended airbag reduces direct contact between the laser and the mounting bracket, lowering friction and vibration. The addition of the indicator ring, scale ring, and pointer does not negatively impact this stability. On the contrary, they help operators perform adjustments more smoothly by providing intuitive adjustment instructions.

[0022] Optionally, the adjusting screw has a cylindrical end located inside the through hole.

[0023] By adopting the above technical solution, the end of the cylindrical adjusting screw can reduce damage to the suspension airbag.

[0024] Optionally, the adjusting screw has a spherical contact end with the laser.

[0025] By adopting the above technical solution, the contact end is spherical, so that when the laser comes into contact with the adjusting screw, the end of the adjusting screw is always tangent, which facilitates the adjustment of the laser position.

[0026] Optionally, each of the suspended airbags has at least two of the through holes.

[0027] By adopting the above technical solution, the setting of two through holes and the corresponding two adjusting screws passing through each airbag can stabilize the position adjustment of the laser, further improve the collimation efficiency, and maintain stability during use.

[0028] Optionally, the mounting bracket is provided with an adjustment assembly, the adjustment assembly including:

[0029] The adjustment plate slides within the mounting cavity of the mounting bracket and abuts against the suspension airbag, squeezing the suspension airbag as it slides.

[0030] An adjusting component is mounted on the mounting frame and connected to the adjusting plate, used to drive the adjusting plate to slide.

[0031] By adopting the above technical solution, when the laser model changes, the position of the adjustment plate is changed by the adjustment component, thereby changing the position of the suspension airbag, so that the suspension airbag can fix lasers of different sizes; at the same time, by adjusting the position of the suspension airbag, the installation of the laser is facilitated, thereby improving collimation efficiency and installation efficiency.

[0032] Optionally, the adjusting member includes:

[0033] A rotating rod is rotatably mounted on the mounting bracket and extends into the mounting cavity;

[0034] A fixing block is provided on the adjustment plate;

[0035] An adjusting block is disposed on the rotating rod and has multiple driving surfaces with different heights. The driving surfaces can abut against the fixed block, and a guide surface is provided between the multiple driving surfaces for smooth transition.

[0036] By adopting the above technical solution, when adjusting the position of the suspension airbag, rotating the rotating rod drives the adjusting block to rotate, so that different driving surfaces abut against the fixed block one by one, thereby changing the position of the adjusting plate. The setting of the adjusting component has a simple structure and is easy to operate, further improving work efficiency.

[0037] Optionally, the adjustment assembly further includes a reset member disposed on the inner wall of the mounting cavity and connected to the adjustment plate, for pulling the adjustment plate away from the suspension airbag.

[0038] By adopting the above technical solution and setting the reset component, the suspended airbag can quickly expand the fixed space, which facilitates the installation of the laser.

[0039] Optionally, the rotating rod is provided with a locking plate, and the mounting bracket is provided with multiple locking slots, the locking plate being able to be inserted into any of the locking slots.

[0040] By adopting the above technical solution, after the position of the suspended airbag is adjusted, the position of the rotating rod is fixed by the locking plate and the locking groove, thereby fixing the position of the suspended airbag and improving the stability of the laser.

[0041] In summary, this application includes at least one of the following beneficial technical effects:

[0042] 1. When collimating the laser, the position of the laser is adjusted by rotating the adjusting screw according to the existing position of the laser. During the adjustment process, the suspended airbag limits the laser and reduces the laser's shaking. The airbag is elastic and does not affect the adjustment of the laser position by the adjusting screw. At the same time, it can make the laser move smoothly, reduce ineffective adjustment, and thus improve work efficiency.

[0043] 2. When adjusting the position of the suspension airbag, rotate the rotating rod, which drives the adjusting block to rotate, so that different driving surfaces abut against the fixed block one by one, thereby changing the position of the adjusting plate. The adjusting component has a simple structure and is easy to operate, further improving work efficiency.

[0044] 3. After the position of the suspended airbag is adjusted, the position of the rotating rod is fixed by the locking plate and the locking groove, thereby fixing the position of the suspended airbag and improving the stability of the laser. Attached Figure Description

Detailed Implementation

[0051] The following combination Figures 1 to 5 This application will be described in further detail.

[0052] This embodiment discloses a laser collimation structure.

[0053] Reference Figure 1 and Figure 2 The laser collimation structure includes: a mounting bracket 100 mounted on the device being used; a laser 800 mounted within the mounting bracket 100; a suspending airbag 200 mounted on the mounting bracket 100 for stabilizing the laser 800; and an adjusting screw 300 threaded onto the mounting bracket 100 for adjusting the position of the laser 800. When installing and adjusting the laser 800, the laser 800 is first placed on the suspending airbag 200 on the mounting bracket 100, thus initially connecting the laser 800 to the device being used via the mounting bracket 100. Then, based on the emission of the laser beam from the laser 800, the position of the laser 800 is adjusted by rotating the adjusting screw 300.

[0054] The equipment used can be a marking machine, a laser cutter, or a laser rangefinder. In this embodiment, a laser cutter is preferred. The mounting bracket 100 is fixedly connected to the laser cutter by bolts or welding. The mounting bracket 100 has a cylindrical mounting cavity 110 inside, and multiple threaded holes are evenly distributed on the inner circumferential wall of the mounting cavity 110 for installing adjusting screws 300. One end of the mounting bracket 100 is open for inserting the laser 800, and the other end is closed and has a light-transmitting hole. When the laser 800 is located in the mounting cavity 110, the laser beam emitted by the emitting end of the laser 800 passes through the light-transmitting hole.

[0055] Reference Figure 3 Four airbags 200 are arranged in a ring array and bonded to the inner peripheral wall of the mounting cavity 110. The four airbags 200 form a fixed space on their adjacent sides, and the laser 800 is placed in the fixed space. Each airbag 200 is made of an elastic material (such as rubber) and has an independent air cavity 220 inside. The air cavity is isolated from the outside of the airbag 200, and the side of the airbag 200 near the middle of the mounting cavity 110 is arc-shaped and in contact with the surface of the laser 800. Two symmetrical through holes 210 are opened on the outer surface of the airbag 200. The axis of the through holes 210 is parallel to the moving axis of the threaded hole, and the through holes 210 penetrate the thickness of the airbag but are not connected to the air cavity. That is, the through holes 210 and the airbag 200 are separated by the elastic material.

[0056] Reference Figure 2 and Figure 3 The number of adjusting screws 300 corresponds to the number of through holes 210, with one adjusting screw 300 inserted into each through hole 210. The threaded section of the adjusting screw 300 mates with the threaded hole of the mounting bracket 100. The end of the screw is cylindrical and the tip is machined into a spherical shape, making point contact with the outer wall of the laser 800. The head of the adjusting screw 300 is hexagonal.

[0057] After the laser 800 is inserted into the mounting cavity 110, it is surrounded by four suspended airbags 200, forming an annular fixing space to initially fix the laser 800. The adjusting screw 300 passes through the threaded hole and the through hole 210. By turning the adjusting screw 300, its spherical end is pushed against the side wall of the laser 800, achieving fine adjustment of the radial position of the laser 800. The elastic deformation of the suspended airbags 200 provides cushioning, avoiding rigid contact damage to the laser 800. Furthermore, the suspended airbags 200 initially fix the laser 800, reducing large-scale shaking during the adjustment process. This enhances the adjustment effectiveness of the adjusting screw 300 and facilitates improved collimation efficiency.

[0058] Reference Figure 1 and Figure 4In other embodiments, the mounting bracket 100 is further provided with an adjustment indicator assembly, including: an indicator ring 400, a scale ring 500, and a pointer 600. Multiple annular grooves are formed on the outer side of the mounting bracket 100, each corresponding to and communicating with a threaded hole. The indicator ring 400 is fitted into the annular groove on the outer periphery of the mounting bracket 100 and rotates within the groove. A sliding hole 410 is formed on the indicator ring 400, the axis of which is parallel to the axis of the adjusting screw 300, and the head of the adjusting screw 300 slides within the sliding hole 410. The scale ring 500 is fixed to the outer periphery of the mounting bracket 100, and its surface is marked with angle graduations. Multiple scale rings 500 are provided, each corresponding to one of the multiple indicator rings 400. The pointer 600 is fixed to the outer edge of the indicator ring 400 and points to the graduations on the scale ring 500.

[0059] The head of the adjusting screw 300 is embedded in the sliding hole 410 of the indicator ring 400. When the adjusting screw 300 is turned, only the indicator ring 400 needs to be rotated. The indicator ring 400 drives the adjusting screw 300 to rotate, so that the head moves linearly along the sliding hole 410. At the same time, it drives the indicator ring 400 to rotate, so that the pointer 600 indicates the adjustment amount along the scale ring 500, realizing visual adjustment.

[0060] In other implementations, such as Figure 2 and Figure 5As shown, an adjustment assembly 700 is added to the mounting cavity 110 of the mounting frame 100, including: an adjustment plate 710, a reset component 730, and an adjustment component 720. The adjustment plate 710 is a strip-shaped plate located outside the suspension airbag 200, with a slot formed on the side of the suspension airbag 200 corresponding to the adjustment plate 710. The adjustment plate 710 is located within the slot and is bonded to the suspension airbag 200. A guide rod 740 is provided between the adjustment plate 710 and the inner wall of the mounting cavity 110, sliding on the inner wall of the mounting cavity 110 to achieve a sliding connection between the adjustment plate 710 and the mounting cavity 110. The reset component 730 is a reset spring, sleeved on the guide rod 740, with both ends of the reset spring connected to the adjustment plate 710 and the inner wall of the mounting cavity 110 respectively, used to pull the adjustment plate 710 in a direction away from the suspension airbag 200. The mounting frame 100 has multiple rotating holes. Between two threaded holes on the same side; the adjusting member 720 includes a rotating rod 721, a fixing block 722, and an adjusting block 723. The rotating rod 721 passes through a rotating hole on the mounting bracket 100 and extends into the mounting cavity 110. The rotating rod 721 can slide and rotate within the rotating hole. One end of the rotating rod 721 located in the mounting cavity 110 is fixedly connected to the adjusting block 723. The cross-sectional area of ​​the end of the adjusting block 723 away from the rotating rod 721 is smaller than the cross-sectional area of ​​the end near the rotating rod 721. The end of the adjusting block 723 away from the rotating rod 721 has a polyhedral structure and forms multiple driving surfaces 725. In this embodiment, four are preferred, and the four driving surfaces 725 have different opening heights. Guide surfaces are provided between the multiple driving surfaces 725 for smooth transition. The adjusting plate 710 is fixedly connected to the side away from the suspension airbag 200 with a fixing block 722. The fixing block 722 can abut against any driving surface 725.

[0061] In other embodiments, in order to facilitate the fixing of the position of the rotating rod 721, a locking plate 724 is fixedly connected to the rotating rod 721. A plurality of locking grooves 120 are provided on the inner wall of the mounting cavity 110. The locking plate 724 is located in the mounting cavity 110 and corresponds to any locking groove 120. The locking plate 724 can be inserted into any locking groove 120 to fix the angle of the rotating rod 721.

[0062] When the rotating rod 721 rotates, the driving surface 725 of the adjusting block 723 pushes the fixing block 722, causing the adjusting plate 710 to slide towards the suspension airbag 200, squeezing the airbag to change its pre-pressure; the reset spring pulls the adjusting plate 710 back to its initial position when it is released; the adjusted state is fixed by the insertion of the locking plate 724 into the locking groove 120.

[0063] The height difference of the driving surface 725 of the adjusting block 723 corresponds to the graded adjustment of the airbag pre-inflation.

[0064] 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.
