Description

Technical Field

[0001] This utility model relates to the field of laser production equipment technology, and in particular to a lens bonding device. Background Technology

[0002] As a key component in solid-state lasers, the lens plays a crucial role in the transmission and transformation of the beam within the laser. Currently, the main steps for installing the lens in the optical path of a solid-state laser are as follows: first, the lens is bonded to the lens mount; then, adhesive is manually mixed and applied to the lens mount; the lens is placed on top of the adhesive and pressed down; an indicator light is shone onto the flat end of the lens; the position of the indicator light reflected from the flat end of the lens is observed; and the angle and position of the lens are manually adjusted; finally, the adhesive is cured.

[0003] The above-mentioned lens bonding method has the drawback of making it difficult to ensure that the workers press the lenses with consistent force, resulting in different bonding heights for each lens. At the same time, the adjustment error is relatively large when relying on manual adjustment of the lens angle, and the lens is prone to slight shaking during the glue curing process, which leads to poor bonding consistency between the lens and the lens mount. Utility Model Content

[0004] The main purpose of this invention is to propose a lens bonding device, which aims to solve the problem of poor bonding consistency between the lens and the lens mount in existing lens bonding methods.

The second drive rod is rotatably connected to the second connecting seat and is threadedly connected to the third connecting seat. The third drive rod is rotatably connected to the third connecting seat and is threadedly connected to the fourth connecting seat.

[0010] According to some embodiments of the present invention, the position adjustment mechanism further includes a base and a fourth drive rod. The base is provided with a fourth guide structure extending in the x-direction. The second connecting seat is movably disposed on the fourth guide structure. The fourth drive rod is fixedly connected to the second connecting seat.

[0011] According to some embodiments of the present invention, the angle adjustment mechanism includes a sliding seat, a driving assembly, and a dual-axis rotation assembly. The first connecting seat has an arc surface on one side in the x-direction. The sliding seat is driven by the driving assembly to slide on the arc surface to rotate about an axis extending in the y-direction. The lens fixing mechanism is mounted on the sliding seat through the dual-axis rotation assembly. The lens fixing mechanism is driven by the dual-axis rotation assembly to rotate about a first axis and a second axis that are perpendicular to each other. Both the first axis and the second axis are perpendicular to the y-direction.

[0012] According to some embodiments of the present invention, the driving assembly includes a first telescopic rod and a first elastic element. The sliding seat is connected to the first connecting seat through the first elastic element. The first telescopic rod is disposed on the first connecting seat. The telescopic direction of the first telescopic rod is perpendicular to the y-direction. The first telescopic rod has a first abutting end that can extend to abut against the sliding seat to drive the sliding seat to slide along the arc surface.

[0013] According to some embodiments of the present invention, the dual-axis rotating assembly includes a first rotating seat, a second rotating seat, a second elastic element, a third elastic element, a second telescopic rod, and a third telescopic rod. The first rotating seat is rotatably connected to the sliding seat about a first axis via the second elastic element.

[0015] This utility model has at least the following beneficial effects:

[0016] In this invention, the lens base is first fixed by the lens base fixing mechanism, and the lens is fixed by the mounting structure of the lens fixing mechanism. Then, a position adjustment mechanism drives the lens fixing mechanism to move closer to the lens base fixing mechanism in the z-direction, causing the lens to move to the bonding position of the lens base fixing mechanism and contact the adhesive of the lens base. Next, an angle adjustment mechanism drives the lens fixing mechanism to rotate around axes extending in the x, y, and z directions respectively to adjust the angle of the lens. After the lens is adjusted to the correct position, the position and angle adjustment mechanisms stop moving. After the adhesive has cured, the mounting structure of the lens fixing mechanism is released from the lens, thus completing the bonding of the lens to the lens base. This invention replaces the original manual pressing and adjustment of the lens by the position and angle adjustment mechanisms, ensuring consistent bonding height for each lens and reducing angle adjustment errors. Furthermore, during adhesive curing, the position and angle adjustment mechanisms remain stationary, and the mounting structure continuously fixes the lens to prevent slight movement, thereby improving the bonding consistency of the lens.

[0028] This utility model provides a lens bonding device. Figures 1 to 5 This is a specific embodiment of a lens bonding device provided by the present invention.

[0029] like Figures 1 to 4 As shown, this utility model embodiment provides a lens bonding device 100, including a lens fixing mechanism 1, a position adjusting mechanism 2, an angle adjusting mechanism 3, and a lens base fixing mechanism 4 for fixing a lens base. The lens fixing mechanism 1 has a mounting structure for detachable installation of the lens, and the lens base fixing mechanism 4 has a bonding position for bonding the lens to the lens base. The lens fixing mechanism 1 is mounted on the position adjusting mechanism 2 via the angle adjusting mechanism 3. The lens fixing mechanism 1 is driven by the position adjusting mechanism 2 to move closer to the lens base fixing mechanism 4 in the z-direction so that the lens can move to the bonding position. The lens fixing mechanism 1 is driven by the angle adjusting mechanism 3 to rotate relative to the lens base fixing mechanism 4 about axes extending in the x-direction, y-direction, and z-direction, respectively.

[0030] In this invention, the lens base is first fixed by the lens base fixing mechanism 4, and the lens is fixed by the mounting structure of the lens fixing mechanism 1. Then, the position adjustment mechanism 2 drives the lens fixing mechanism 1 to move closer to the lens base fixing mechanism 4 in the z direction, so that the lens moves to the bonding position of the lens base fixing mechanism 4 and contacts the adhesive of the lens base. Then, the angle adjustment mechanism 3 drives the lens fixing mechanism 1 to rotate around the axis extending in the x direction, the axis extending in the y direction, and the axis extending in the z direction, respectively, to adjust the angle of the lens. After the lens is adjusted to the position, the position adjustment mechanism 2 and the angle adjustment mechanism 3 stop moving. After the adhesive has cured, the mounting structure of the lens fixing mechanism 1 is released from the lens to complete the bonding of the lens to the lens base. This invention replaces the original manual pressing and adjustment of the lenses by the position adjustment mechanism 2 and the angle adjustment mechanism 3, ensuring that the bonding height of each lens is consistent and reducing the error of the adjustment angle. At the same time, during the adhesive curing process, the position adjustment mechanism 2 and the angle adjustment mechanism 3 stop moving and the mounting structure always fixes the lens to avoid slight shaking of the lens, thereby improving the bonding consistency of the lens.

[0031] Workers can determine that the lens is properly adjusted in various ways, such as in some embodiments, like Figure 1As shown, the lens bonding device 100 also includes a laser emitting mechanism 5. The bonding position of the lens mount fixing mechanism 4 is located in the optical path of the laser light emitted by the laser emitting mechanism 5, so that after the lens is moved to the bonding position, the angle adjustment mechanism 3 adjusts the flat end of the lens to be perpendicular to the optical path of the laser light emitted by the laser emitting mechanism 5. Since the flat end of the lens is a reflective surface, the worker adjusts the angle of the lens through the angle adjustment mechanism 3 while observing the position of the reflected light from the lens. When the optical path of the reflected light from the lens coincides with the optical path of the laser light emitted by the laser emitting mechanism 5, it indicates that the flat end of the lens is perpendicular to the laser light emitted by the laser emitting mechanism 5, and the lens has been adjusted to the correct position.

[0032] The specific structure of the laser emitting mechanism 5 is not limited, as long as the bonding position of the mirror mounting mechanism 4 is located in the optical path of the emitted light from the laser emitting mechanism 5. For example, in some embodiments, such as... Figure 1 As shown, the laser emitting mechanism 5 includes a laser light source 51 and a reflector group 52. The reflector group 52 is positioned in the optical path of the laser light emitted from the laser light source 51, so that it reflects the emitted light to the bonding position of the lens mounting mechanism 4. This arrangement, relying on the reflector group 52 to reflect the emitted light from the laser light source 51, allows for unrestricted placement of the laser light source 51, improving the applicability of the lens bonding device 100. Specifically, the reflector group 52 includes at least one reflecting lens 521.

[0033] It should be noted that the lens bonding device 100 also includes two cameras, one of which is used to monitor the optical path position of the light reflected from the lens, and the other camera is used to monitor the curing of the adhesive, thereby reducing the error of the worker's naked eye observation and improving the bonding consistency of the lens.

[0034] Furthermore, in some embodiments, such as Figure 1 As shown, the lens bonding device 100 also includes a base 6, on which the laser emitting mechanism 5, the lens mount fixing mechanism 4, and the position adjustment mechanism 2 are all mounted. This arrangement, by placing all components on the base 6, facilitates the movement of the lens bonding device 100.

[0035] Preferably, in some embodiments, such as Figure 1As shown, the lens bonding device 100 further includes an adhesive curing mechanism 7, which includes a bracket 71 and an ultraviolet curing lamp 72. The ultraviolet curing lamp 72 is mounted on the base 6 via the bracket 71, and the lens mount fixing mechanism 4 is located within the irradiation area of ​​the ultraviolet curing lamp 72. This arrangement, by irradiating the lens mount and lens on the lens mount fixing mechanism 4 with the ultraviolet curing lamp 72, accelerates the curing of the adhesive and improves the bonding efficiency between the lens and the lens mount.

[0036] The specific structure of the mirror mount fixing mechanism 4 is not limited, as long as it ensures that the mirror mount fixing mechanism 4 can fix the mirror mount. For example, in some embodiments, such as... Figure 5 As shown, the lens mount fixing mechanism 4 includes two pressing blocks 41 and two abutting blocks 42 that can respectively abut against the adjacent two sides of the lens mount. The two pressing blocks 41 and the two abutting blocks 42 are respectively arranged opposite to each other in the x and y directions, and are respectively close to the corresponding abutting blocks 42 in the x and y directions. With this arrangement, the lens mount is clamped by the cooperation of the two pressing blocks 41 and the two abutting blocks 42, which can accommodate lens mounts of various sizes compared to conventional locking grooves.

[0037] The specific structure of the position adjustment mechanism 2 is not limited, as long as it ensures that the position adjustment mechanism 2 can drive the lens fixing mechanism 1 to move closer to the lens mount fixing mechanism 4 in the z-direction. For example, in some embodiments, such as... Figures 2 to 4 As shown, the position adjustment mechanism 2 includes an xy drive platform 21 and a first connecting seat 22. The xy drive platform 21 is provided with a first guide structure 23 extending along the z-direction. The first connecting seat 22 is movably mounted on the first guide structure 23. The lens fixing mechanism 1 is connected to the first connecting seat 22 through the angle adjustment mechanism 3. The lens fixing mechanism 1 is driven by the xy drive platform 21 to move relative to the lens mount fixing mechanism 4 in the x and y directions. With this configuration, the first connecting seat 22 moves on the first guide structure 23, which can drive the angle adjustment mechanism 3 and the lens fixing mechanism 1 to move in the z-direction. At the same time, the xy drive platform 21 drives the lens fixing mechanism 1 to move in the x and y directions, realizing the position adjustment of the lens in three-dimensional space. Since the rotation of the lens fixing mechanism 1 driven by the angle adjustment mechanism 3 will cause the position of the lens in three-dimensional space to change, it is necessary to use the xy drive platform 21 and the first connecting seat 22 to correct the position of the lens.

[0038] The specific structure of the xy driving platform 21 is not limited, as long as it ensures that the xy driving platform 21 can drive the lens fixing mechanism 1 to move in the x and y directions. For example, in some embodiments, such as... Figures 2 to 4 As shown, the xy driving platform 21 includes a second connecting seat 211, a third connecting seat 212, and a fourth connecting seat 213. The second connecting seat 211 has a second guide structure 214 extending along the y-direction. The third connecting seat 212 is movably mounted on the second guide structure 214. The third connecting seat 212 has a third guide structure 215 extending along the x-direction. The fourth connecting seat 213 is movably mounted on the third guide structure 215. The fourth connecting seat 213 has a first guide structure 23. With this configuration, since the second guide structure 214 and the third guide structure 215 extend along the y-direction and x-direction respectively, the movement of the third connecting seat 212 on the second guide structure 214 and the movement of the fourth connecting seat 213 on the third guide structure 215 can drive the lens fixing mechanism 1 to move in the x-direction and y-direction respectively.

[0039] Furthermore, in some embodiments, such as Figures 2 to 4 As shown, the position adjustment mechanism 2 further includes a first drive rod 24, and the xy drive platform 21 further includes a second drive rod 216 and a third drive rod 217. The first drive rod 24 is rotatably connected to the fourth connecting seat 213 and is threadedly connected to the first connecting seat 22. The second drive rod 216 is rotatably connected to the second connecting seat 211 and is threadedly connected to the third connecting seat 212. The third drive rod 217 is rotatably connected to the third connecting seat 212 and is threadedly connected to the fourth connecting seat 213. With this configuration, the driving principle of each drive rod is similar to that of a ball screw structure. By rotating the first drive rod 24, the second drive rod 216, and the third drive rod 217, the first connecting seat 22, the third connecting seat 212, and the fourth connecting seat 213 can be translated in the z, y, and x directions, respectively. Simultaneously, the rotation of each drive rod allows for fine adjustment of each connecting seat, thereby improving the adjustment accuracy of the lens position.

[0040] It should be noted that, as Figures 2 to 4 As shown, the position adjustment mechanism 2 also includes three handles 28, which are respectively positioned corresponding to the first drive rod 24, the second drive rod 216, and the third drive rod 217. The worker can hold one handle 28 with one hand and the drive rod with the other, facilitating the worker to apply force to the drive rods to rotate them.

[0041] Since a large gap needs to be maintained between the lens fixing mechanism 1 and the lens mount fixing mechanism 4 when fixing the lens and the lens mount, to prevent workers from bumping into other parts during fixing, but the adjustment efficiency of the lens position by driving a drive rod is low, therefore in some embodiments, such as Figures 2 to 4 As shown, the position adjustment mechanism 2 further includes a base 25 and a fourth drive rod 26. The base 25 is provided with a fourth guide structure 27 extending in the x-direction. The second connecting seat 211 is movably disposed on the fourth guide structure 27, and the fourth drive rod 26 is fixedly connected to the second connecting seat 211. With this configuration, after the worker fixes the lens and the lens mount to the lens fixing mechanism 1 and the lens mount fixing mechanism 4 respectively, he can hold the fourth drive rod 26 to quickly adjust the position of the lens fixing mechanism 1 in the x-direction to complete the coarse position adjustment. Then, the first drive rod 24, the second drive rod 216, and the third drive rod 217 are used for fine position adjustment, thereby improving the position adjustment efficiency of the lens.

[0042] The specific structure of the angle adjustment mechanism 3 is not limited, as long as it ensures that the angle adjustment mechanism 3 can drive the lens fixing mechanism 1 to rotate about the axes extending in the x-direction, y-direction, and z-direction, respectively. For example, in some embodiments, such as... Figures 2 to 4 As shown, the angle adjustment mechanism 3 includes a sliding seat 31, a driving assembly 32, and a dual-axis rotation assembly 33. The first connecting seat 22 has an arc surface 221 on one side in the x direction. The sliding seat 31 is driven by the driving assembly 32 to slide on the arc surface 221 and rotate about an axis extending in the y direction. The lens fixing mechanism 1 is mounted on the sliding seat 31 through the dual-axis rotation assembly 33. The lens fixing mechanism 1 is driven by the dual-axis rotation assembly 33 to rotate about a first axis and a second axis that are perpendicular to each other. Both the first axis and the second axis are perpendicular to the y direction. With this configuration, when the sliding seat 31 slides on the arc surface 221, it is equivalent to rotating around the axis extending in the y direction, thereby driving the lens fixing mechanism 1 to rotate around the axis extending in the y direction. When the sliding seat 31 stops sliding and the dual-axis rotation assembly 33 is just on one side of the sliding seat 31 in the x direction, one of the first axis and the second axis is parallel to the x direction, and the other is parallel to the z direction. At this time, the dual-axis rotation assembly 33 can drive the lens fixing mechanism 1 to rotate around the axes extending in the x and z directions.

[0043] Furthermore, in some embodiments, such as Figures 2 to 4As shown, the driving assembly 32 includes a first telescopic rod 321 and a first elastic element. The sliding seat 31 is connected to the first connecting seat 22 via the first elastic element. The first telescopic rod 321 is disposed on the first connecting seat 22, and the telescopic direction of the first telescopic rod 321 is perpendicular to the y-direction. The first telescopic rod 321 has a first abutting end that can extend to abut against the sliding seat 31 to drive the sliding seat 31 to slide along the arc surface 221. With this configuration, when the first telescopic rod 321 extends, it can drive the sliding seat 31 to slide upwards or downwards along the arc surface 221, causing the first elastic element to deform. When the first telescopic rod 321 retracts, under the elastic force of the first elastic element, the sliding seat 31 returns to its original position and slides in the opposite direction. Through the cooperation of the first telescopic rod 321 and the first elastic element, the sliding seat 31 can slide upwards or downwards along the arc surface 221. Specifically, the first elastic element is a spring.

[0044] In some embodiments, such as Figures 2 to 4 As shown, the dual-axis rotating assembly 33 includes a first rotating seat 331, a second rotating seat 332, a second elastic element, a third elastic element, a second telescopic rod 333, and a third telescopic rod 334. The first rotating seat 331 is rotatably connected to the sliding seat 31 about a first axis through the second elastic element. The second rotating seat 332 is rotatably connected to the first rotating seat 331 about a second axis through the third elastic element. The second rotating seat 332 is connected to the lens fixing mechanism 1. The second telescopic rod 333 and the third telescopic rod 334 are both disposed on the first rotating seat 331. The extension direction of the second telescopic rod 333 is perpendicular to the first axis. The second telescopic rod 333 has a second abutment end that can extend to abut against the sliding seat 31 to drive the first rotating seat 331 to rotate. The extension direction of the third telescopic rod 334 is perpendicular to the second axis. The third telescopic rod 334 has a third abutment end that can extend to abut against the second rotating seat 332 to drive the second rotating seat 332 to rotate. Similarly, the first rotating seat 331 can rotate clockwise or counterclockwise through the cooperation of the second telescopic rod 333 and the second elastic element, and the second rotating seat 332 can rotate clockwise or counterclockwise through the cooperation of the third telescopic rod 334 and the third elastic element. Specifically, the second elastic element and the third elastic element are torsion springs.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
