Description

Technical Field

[0001] This application relates to the field of field lens adjustment technology, and in particular to an achromatic field lens adjustment device. Background Technology

[0002] An achromatic field lens is an optical element primarily used to correct chromatic aberration between laser wavelengths (such as 355nm) and visual wavelengths (such as the common 633nm). An achromatic field lens contains multiple lenses, which are arranged to ensure that the laser and visual imaging light are completely coaxial and focused to the same point, causing their focal planes to coincide. Therefore, after the achromatic field lens is assembled, it needs to be adjusted to meet the required effects.

[0003] Currently, existing achromatic field lenses are often not accurately positioned during use, and they tend to wobble during adjustment. Furthermore, they cannot be accurately extended after adjustment, which hinders manual handling and affects processing efficiency. Therefore, there is room for improvement in the existing achromatic field lens adjustment devices. Summary of the Invention

[0004] In order to accurately adjust and process achromatic field lenses, this application provides an achromatic field lens adjustment device.

[0005] The achromatic field lens adjustment device provided in this application adopts the following technical solution:

[0006] An achromatic field lens adjustment device includes an L-shaped bracket; a laser emitter mounted on one side of the upper end of the L-shaped bracket, the laser emitter being used to generate a laser beam; a rotation adjustment assembly mounted in the middle of the upper end of the L-shaped bracket, the rotation adjustment assembly being used to drive the achromatic field lens to rotate intermittently; and a test plate mounted on the L-shaped bracket, the test plate being on the same axis as the center of the laser emitter, the laser beam generated by the laser emitter passing through the achromatic field lens and then illuminating the test plate, the test plate being used to record the size and shape of the light spot.

[0007] Furthermore, the rotation adjustment assembly includes a fixed column, a rotating frame, a positioning groove, a pushing unit, and an adjustment unit. The fixed column is installed in the middle of the upper end of the L-shaped bracket, and the rotating frame is installed on the upper end of the fixed column.

The achromatic field lens is placed inside the positioning groove. Pushing units are evenly installed in the middle of the rotating frame, and each pushing unit corresponds to a positioning groove. An adjustment unit is provided at the lower end of the positioning groove and is installed at the lower end of the rotating frame.

[0008] Furthermore, anti-detachment blocks are symmetrically installed on the inner end of the positioning groove. The anti-detachment blocks have a triangular structure and are made of flexible rubber.

[0009] Furthermore, the pushing unit includes a sliding frame, an annular groove one, an annular groove two, a guide rod, a telescopic spring, and a pushing plate. The rotating frame has a sliding groove evenly arranged in the middle, and the sliding frame is slidably arranged up and down in the sliding groove. An annular groove one is provided on the fixed column, and an annular groove two is provided on the upper and lower sides of the annular groove one. A slider that cooperates with the annular groove two is provided on the sliding frame. A through hole is provided in the middle of the sliding frame, and a guide rod is slidably arranged in the through hole. A telescopic spring is provided on the guide rod, and the inner end of the guide rod is slidably arranged inside the annular groove one. A pushing plate is installed on the outer end of the guide rod.

[0010] Furthermore, the annular groove has a circular structure, and the depth of the annular groove gradually decreases from left to right.

[0011] Furthermore, the second annular groove has a circular structure and gradually slopes upward from left to right.

[0012] Furthermore, the pusher plate has an arc-shaped structure, and a magnet is provided on the concave surface of the pusher plate.

The support frame has a U-shaped structure and is located at the lower end of the positioning groove. Debugging frames are symmetrically installed on the support frame. The debugging frames are rotatable. The lower end of the achromatic field lens is inserted into the debugging frame.

[0014] In the above technical solution, the present invention provides an achromatic field lens adjustment device. The rotating adjustment component in the present invention can position the achromatic field lens and drive it to rotate intermittently. The adjustment unit can accurately adjust the spacing between the lenses inside the achromatic field lens. After the achromatic field lens is tested, the pushing unit first lifts the achromatic field lens upward, so that the lower end of the achromatic field lens is separated from the adjustment unit.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-5 The present invention provides an achromatic field lens adjustment device, comprising an L-shaped bracket 1; a laser emitter 2, which is installed on one side of the upper end of the L-shaped bracket 1, and the laser emitter 2 is used to generate a laser beam; a rotation adjustment component 3, which is installed in the middle of the upper end of the L-shaped bracket 1, and the rotation adjustment component 3 is used to drive the achromatic field lens to rotate intermittently; and a test plate 4, which is installed on the L-shaped bracket 1, with the test plate 4 and the laser emitter 2 on the same axis. The laser beam generated by the laser emitter 2 passes through the achromatic field lens and then illuminates the test plate 4, and the test plate 4 is used to record the size and shape of the light spot.

[0024] In the above technical solution, the achromatic scenes to be debugged are placed one by one on the rotating debugging component 3. The rotating debugging component 3 drives the achromatic scenes to rotate intermittently. When the achromatic scene rotates to the position directly below the laser emitter 2, the laser beam generated by the laser emitter 2 passes through the achromatic field lens and illuminates the test plate 4. The test plate 4 is used to record the size and shape of the light spot, so that the laser and the visual imaging light are completely coaxial and focused on the same point, so that the focal planes of the two coincide. This characteristic helps to achieve clear imaging of the CCD within the field of view and meets the needs of visual positioning laser processing.

[0025] See Figure 1-3As shown, in this preferred embodiment, the rotating adjustment assembly 3 includes a fixed column 31, a rotating frame 32, a positioning groove 33, a pushing unit 34, and an adjustment unit 35. The fixed column 31 is installed in the middle of the upper end of the L-shaped bracket 1, and the rotating frame 32 is installed on the upper end of the fixed column 31. The rotating frame 32 is rotatably set and has a U-shaped cross-section. Positioning grooves 33 are evenly arranged on the outer side of the rotating frame 32. The achromatic field lens is placed inside the positioning groove 33. The pushing unit 34 is evenly installed in the middle of the rotating frame 32. The pushing unit 34 corresponds one-to-one with the positioning groove 33. The adjustment unit 35 is set at the lower end of the positioning groove 33 and is installed at the lower end of the rotating frame 32.

[0026] In the above technical solution, the achromatic field lens to be processed is placed inside the positioning groove 33 on the outside of the rotating frame 32. At the same time, the lower end of the achromatic field lens is inserted and engaged with the adjustment unit 35. The rotating frame 32 can drive the achromatic field lens to rotate intermittently. When the achromatic field lens rotates to directly below the laser emitter 2, the laser emitter 2 generates a laser beam that passes through the inside of the achromatic field lens. By adjusting the spacing between the lenses inside the achromatic field lens through the adjustment unit 35, the laser beam can be completely coaxial with the visual imaging light and focused on the same point to meet the subsequent use requirements of the achromatic field lens. After the achromatic field lens is adjusted, the pushing unit 34 first lifts the achromatic field lens upward and then pushes it outward.

[0027] See Figure 4 As shown, as a preferred technical solution in this embodiment, anti-detachment blocks 331 are symmetrically installed on the inner end of the positioning groove 33. The anti-detachment blocks 331 have a triangular structure and are made of flexible rubber.

[0028] In the above technical solution, when the achromatic field lens is placed inside the positioning groove 33, the anti-detachment block 331 can limit the position of the achromatic field lens, prevent the achromatic field lens from shaking or falling off inside the positioning groove 33, and ensure the positioning accuracy of the achromatic field lens.

[0029] See Figure 5As shown, in this preferred embodiment, the pushing unit 34 includes a sliding frame 341, an annular groove 342, an annular groove 343, a guide rod 344, a telescopic spring 345, and a pushing plate 346. The rotating frame 32 has a sliding groove evenly arranged in the middle, and the sliding frame 341 is slidably arranged up and down in the sliding groove. The fixed column 31 is provided with an annular groove 342, and an annular groove 343 is provided on the upper and lower sides of the annular groove 342. The sliding frame 341 is provided with a slider that cooperates with the annular groove 343. The sliding frame 341 is provided with a through hole in the middle, and the guide rod 344 is slidably arranged in the through hole. The guide rod 344 is provided with a telescopic spring 345. The inner end of the guide rod 344 is slidably arranged inside the annular groove 342, and the outer end of the guide rod 344 is installed with a pushing plate 346.

[0030] See Figure 5 As shown, as a preferred technical solution in this embodiment, the annular groove 342 has a circular annular structure, and the depth of the annular groove 342 gradually decreases from left to right.

[0031] Continue reading Figure 5 As shown, as a preferred technical solution in this embodiment, the annular groove 343 has a circular structure and gradually slopes upward from left to right.

[0032] In the above technical solution, when the rotating frame 32 rotates, the rotating frame 32 can drive the sliding frame 341 to move synchronously. The gradually upward tilting annular groove 343 can drive the sliding frame 341 to move upward, so that the pusher plate 346 can drive the achromatic field mirror to move upward. The lower end of the achromatic field mirror separates from the debugging unit 35. Then, the annular groove 342 drives the achromatic field mirror to be gradually pushed outward through the guide rod 344, so that the debugged achromatic field mirror can be moved out of the positioning groove 33, which is convenient for the continuous processing of the achromatic field mirror.

[0033] As a preferred technical solution in this embodiment, the pusher plate 346 has an arc-shaped structure, and a magnet is provided on the concave surface of the pusher plate 346.

[0034] In the above technical solution, the magnet on the concave surface of the pusher plate 346 can be accurately attracted and fixed to the outer wall of the achromatic field mirror, which makes it easy for the pusher plate 346 to drive the achromatic field mirror upward, and facilitates the accurate removal of the achromatic field mirror; when the achromatic field mirror is completely pushed out, the pushed achromatic field mirrors can be collected one by one manually.

[0035] See Figures 4-5As shown, as a preferred technical solution in this embodiment, the debugging unit 35 includes a support frame 351 and a debugging frame 352. The support frame 351 is installed at the lower end of the rotating frame 32. The support frame 351 has a U-shaped structure and is located at the lower end of the positioning groove 33. The debugging frame 352 is symmetrically installed on the support frame 351. The debugging frame 352 is rotatably set, and the lower end of the achromatic field lens is inserted into the debugging frame 352.

[0036] In the above technical solution, when the achromatic field lens is manually placed inside the positioning slot 33, the lower end of the achromatic field lens is inserted into the adjustment frame 352. The two adjustment frames 352 can rotate synchronously to adjust the spacing between the lenses inside the achromatic field lens, thereby achieving the function of adjusting the achromatic field lens, so that the laser beam can be completely coaxial with the visual imaging light and focused on the same point, so as to meet the subsequent use requirements of the achromatic field lens.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
