Description

Technical Field

[0001] This invention relates to a limiting device, and more particularly to an optical lens detection limiting device. Background Technology

[0002] In recent years, optical lenses have been applied to various fields, and the quality requirements for optical crystals have become increasingly stringent. Therefore, optical lenses need to be inspected after processing. During the inspection of optical lens components, it is necessary to limit and fix the optical lenses.

[0003] Patent CN215573698U discloses a fixing device for optical lens inspection. This device includes a base with a mounting box fixedly installed on its top. By activating a servo motor, the output shaft of the servo motor rotates, driving a drive gear. The drive gear drives a driven gear, which in turn drives a bidirectional threaded rod. The bidirectional threaded rod causes two first threaded sleeves connected to its external threads to move relative to or away from each other. Simultaneously, a turntable rotates, causing the threaded rod to rotate. The two threaded rods then cause two second threaded sleeves connected to their external threads to move away from each other. The second threaded sleeves push a roller that is in contact with them downwards via a wedge block. The roller, through a sliding plate, drives two T-shaped clamping blocks above it downwards, thereby clamping and fixing optical lenses of different sizes, improving the inspection efficiency of optical lenses. However, this fixing device is inconvenient to operate when picking up or placing optical lenses, and it lacks a cleaning function; impurities on the surface of the optical lenses can easily affect the inspection accuracy.

[0004] Therefore, we propose an optical lens detection and limiting device that is convenient for picking up and placing and can clean optical lenses. Summary of the Invention

[0005] In order to overcome the shortcomings of existing fixed optical lens devices, such as inconvenience in picking up and placing optical lenses and lack of cleaning function, the technical problem is to provide an optical lens detection and limiting device that is convenient to pick up and place and can clean optical lenses.

[0006] An optical lens detection and limiting device includes a detector, a placement seat, a placement plate, a lifting mechanism, and a cleaning mechanism. The lower part of the detector is connected to the placement seat, and the upper part of the placement seat is slidably connected to the placement plate. The placement plate is provided with a lifting mechanism for pushing out the optical lens, and the placement seat is provided with a cleaning mechanism for cleaning impurities on the surface of the optical lens.

[0007] Furthermore, it also includes a limit ring, which is connected to the front of the placement plate.

[0008] Furthermore, the lifting mechanism includes a first rotating plate, a connecting block, a disc, and torsion springs. The first rotating plate is rotatably connected to the front of the placement plate. The first rotating plate moves backward to contact the placement seat and is then squeezed and rotated by the placement seat. The connecting block is rotatably connected to the rear of the first rotating plate. A disc for placing optical lenses is rotatably connected to the upper part of the connecting block. The disc is located inside the limiting ring. Two torsion springs are connected between the first rotating plate and the placement plate.

[0009] Furthermore, the cleaning mechanism includes a mounting bracket, a sliding rod, a first spring, and an electric cleaning brush. The mounting bracket is connected to the front part of the upper part of the mounting base, and the sliding rod is slidably connected to the middle of the mounting bracket. The first spring is connected between the sliding rod and the mounting bracket, and the electric cleaning brush is connected to the lower part of the sliding rod. The electric cleaning brush cleans the impurities on the surface of the optical lens.

[0010] Furthermore, it also includes a correction mechanism for calibrating the position of the optical lens. The correction mechanism includes a mounting block, a slide bar, a second spring, and a correction ring. The mounting block is connected to the upper part of the detector, and the slide bar is slidably connected to the front of the mounting block. The second spring is connected between the slide bar and the mounting block. The correction ring is connected to the lower part of the slide bar. The correction ring moves downward to align the optical lens.

[0011] Furthermore, it also includes a fixing mechanism for fixing the position of the placement plate. The fixing mechanism includes guide blocks, handles and locking blocks. Guide blocks are symmetrically connected to the left and right sides of the front side of the placement plate. A handle is slidably connected between the two guide blocks. Locking blocks are connected to both sides of the handle. When the locking blocks move backward, they contact the placement seat and lock into the placement seat to fix the position of the placement plate.

[0012] Furthermore, it also includes a rotating mechanism for automatically sliding the slide bar downwards. The rotating mechanism includes a crossbar, an L-shaped rod, a second rotating plate, a contact block, and a push block. The lower part of the slide bar is connected to the crossbar, and the upper left rear part of the placement seat is connected to the L-shaped rod. The upper part of the L-shaped rod is rotatably connected to the second rotating plate, which is slidably connected to the crossbar. The lower part of the second rotating plate is connected to the contact block, and the left rear part of the placement plate is connected to the push block. The push block moves backwards to contact the contact block, thereby squeezing the contact block to swing.

[0013] Furthermore, it also includes a pressing mechanism for automatically sliding the sliding rod downward. The pressing mechanism includes a horizontal plate, a contact rod, and a pressing block. The horizontal plate is connected to the middle of the sliding rod, and the contact rod is connected to the right side of the horizontal plate. The contact rod is slidably connected to the mounting bracket. The pressing block is connected to the front right side of the placement plate. The pressing block moves backward to contact the contact rod, thereby squeezing the contact rod to slide downward.

[0014] The present invention has the following advantages: 1. The optical lens is placed on the disc, and the placement plate moves backward so that the disc moves the optical lens downward into the limiting ring for limiting. Then, the impurities on the surface of the optical lens are cleaned by an electric cleaning brush to improve the detection accuracy. After the detection is completed, the placement plate moves forward so that the disc moves upward to push the optical lens out for easy removal.

[0015] 2. The correction ring moves downwards, squeezing the optical lens toward the center of the disk, so that the optical lens is directly below the detection port of the detector, making it easier to perform the detection work.

[0016] 3. The locking block moves downwards and engages with the placement seat, thereby fixing the position of the placement plate and preventing abnormal movement of the placement plate during testing.

[0017] 4. The placement plate moves backward, and through the cooperation of the contact block and the push block, the correction ring moves downward automatically to correct the position of the optical lens.

[0018] 5. The placement plate moves backward and, through the cooperation of the pressing block and the contact rod, automatically moves the electric cleaning brush downward to clean the optical lens. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0030] Example 1

[0031] An optical lens detection and limiting device, such as Figures 1-5 As shown, it includes a detector 1, a placement seat 2, a placement plate 3, a lifting mechanism 4, and a cleaning mechanism 5. The placement seat 2 is installed at the lower part of the detector 1, and the placement plate 3 is slidably connected to the upper part of the placement seat 2. The lifting mechanism 4 is provided on the placement plate 3, which can push out the optical lens. The cleaning mechanism 5 is provided on the placement seat 2, which can clean impurities on the surface of the optical lens.

[0032] like Figure 3 As shown, it also includes a limiting ring 10, and the front part of the placement plate 3 is connected to the limiting ring 10.

[0033] When using the device, the operator places the optical lens to be tested on the lifting mechanism 4, and then pushes the placement plate 3 to slide backward on the placement seat 2. The backward sliding of the placement plate 3 causes the lifting mechanism 4 to move downward into the limiting ring 10, which limits the optical lens. After the placement plate 3 moves the optical lens to below the cleaning mechanism 5, the cleaning mechanism 5 cleans the impurities on the surface of the optical lens, improving the accuracy of the test. After cleaning, the placement plate 3 continues to slide backward, moving the optical lens backward, and the tester 1 tests the optical lens.

[0034] like Figure 1 , Figure 3 and Figure 4As shown, the lifting mechanism 4 includes a first rotating plate 41, a connecting block 42, a disc 43, and a torsion spring 44. The first rotating plate 41 is rotatably connected to the front of the placement plate 3. The first rotating plate 41 moves backward to contact the placement seat 2. The connecting block 42 is rotatably connected to the rear of the first rotating plate 41. The disc 43 is rotatably connected to the upper part of the connecting block 42. The disc 43 can hold optical lenses and is located inside the limiting ring 10. Two torsion springs 44 are connected between the first rotating plate 41 and the placement plate 3.

[0035] When using the device, the operator places the optical lens to be tested on the disc 43. When the placement plate 3 slides backward, the entire lifting mechanism 4 also moves backward. When the first rotating plate 41 moves backward to contact the placement seat 2, the front of the first rotating plate 41 is squeezed upward by the placement seat 2 and the rear rotates downward. The torsion spring 44 deforms, and the rear of the first rotating plate 41 rotates downward, driving the disc 43 to slide downward through the connecting block 42. The disc 43 slides downward, causing the optical lens to move downward into the limiting ring 10. After the test is completed, the placement plate 3 slides forward, causing the first rotating plate 41 to move forward. When the first rotating plate 41 moves forward and disengages from the placement seat 2, the first rotating plate 41 reverses under the action of the torsion spring 44, driving the disc 43 to slide upward through the connecting block 42. The disc 43 slides upward, pushing the optical lens out for easy handling by the operator.

[0036] like Figure 1 and Figure 5 As shown, the cleaning mechanism 5 includes a mounting bracket 51, a sliding rod 52, a first spring 53, and an electric cleaning brush 54. The mounting bracket 51 is bolted to the front of the upper part of the placement seat 2. The sliding rod 52 is slidably connected to the middle of the mounting bracket 51. The first spring 53 is connected between the sliding rod 52 and the mounting bracket 51. The electric cleaning brush 54 is connected to the lower part of the sliding rod 52.

[0037] When using the device, when the placement plate 3 moves the optical lens backward to below the electric cleaning brush 54, the operator pushes the sliding rod 52 downward. The first spring 53 deforms, and the sliding rod 52 moves downward, causing the electric cleaning brush 54 to move downward to clean the impurities on the surface of the optical lens, thus improving the accuracy of the detection. After cleaning, the operator releases the sliding rod 52. Under the action of the first spring 53 resetting, the sliding rod 52 then moves the electric cleaning brush 54 upward to reset.

[0038] Example 2

[0039] Based on Example 1, such as Figure 1 and Figure 6As shown, it also includes a correction mechanism 6, which can correct the position of the optical lens. The correction mechanism 6 includes a mounting block 61, a slide rod 62, a second spring 63, and a correction ring 64. The mounting block 61 is welded to the upper part of the detector 1. The slide rod 62 is slidably connected to the front of the mounting block 61. The second spring 63 is connected between the slide rod 62 and the mounting block 61. The correction ring 64 is welded to the lower part of the slide rod 62.

[0040] When using the device, after the placement plate 3 moves the optical lens to the rearmost position, the operator pushes the slide bar 62 downwards. The second spring 63 deforms, and the slide bar 62 moves downwards, causing the correction ring 64 to move downwards. The downward movement of the correction ring 64 compresses the optical lens towards the center of the disk 43, so that the optical lens is located directly below the detection port of the detector 1, making it easier to perform the detection work. After the detection is completed, the operator releases the slide bar 62. Under the action of the second spring 63 resetting, the slide bar 62 then moves the correction ring 64 upwards to reset.

[0041] like Figure 1 and Figure 7 As shown, it also includes a fixing mechanism 7, which can fix the position of the placement plate 3. The fixing mechanism 7 includes a guide block 71, a handle 72 and a locking block 73. The guide blocks 71 are symmetrically welded to the left and right sides of the front side of the placement plate 3. The handle 72 is slidably connected between the two guide blocks 71. The left and right sides of the handle 72 are both welded with locking blocks 73. When the locking blocks 73 move backward, they contact the placement seat 2.

[0042] When using the device, the operator pushes the placement plate 3 backward by pushing the handle 72. The backward movement of the handle 72 causes the locking block 73 to move backward. When the locking block 73 moves backward and contacts the placement seat 2, the locking block 73 continues to move backward and is squeezed upward by the placement seat 2. The upward movement of the locking block 73 causes the handle 72 to slide upward on the guide block 71. When the locking block 73 moves backward and engages with the placement seat 2, under the action of gravity, the handle 72 drives the locking block 73 to move downward and lock into the placement seat 2, thereby fixing the position of the placement plate 3 and preventing abnormal movement of the placement plate 3 during testing. After the test is completed, the operator pulls the handle 72 to slide upward, thereby causing the locking block 73 to move upward. Then the operator pulls the handle 72 forward, and the forward movement of the handle 72 causes the locking block 73 to move forward and disengage from the placement seat 2. At the same time, the forward movement of the handle 72 also causes the placement plate 3 to slide forward and extend.

[0043] like Figure 1 and Figure 8As shown, it also includes a rotating mechanism 8, which can automatically make the slide bar 62 slide downward. The rotating mechanism 8 includes a crossbar 81, an L-shaped bar 82, a second rotating plate 83, a contact block 84, and a pushing block 85. The crossbar 81 is welded to the lower part of the slide bar 62, and the L-shaped bar 82 is welded to the upper left rear part of the placement seat 2. The second rotating plate 83 is rotatably connected to the upper part of the L-shaped bar 82. The second rotating plate 83 is slidably connected to the crossbar 81. The contact block 84 is welded to the lower part of the second rotating plate 83, and the pushing block 85 is welded to the left rear part of the placement plate 3. The pushing block 85 moves backward and contacts the contact block 84.

[0044] When using the device, the placement plate 3 slides backward, causing the push block 85 to move backward. When the push block 85 moves backward and contacts the contact block 84, the push block 85 continues to move backward, squeezing the contact block 84 to swing backward. The contact block 84 swings backward, causing the second rotating plate 83 to swing forward. The second rotating plate 83 swings forward, causing the crossbar 81 to move downward. The crossbar 81 moves downward, causing the slide bar 62 to slide downward, thereby automatically causing the correction ring 64 to move downward to correct the position of the optical lens. When the placement plate 3 slides forward, causing the push block 85 to move forward and disengage from the contact block 84, the slide bar 62 slides upward, causing the crossbar 81 to move upward. The crossbar 81 moves upward, causing the second rotating plate 83 to swing backward, and the contact block 84 swings forward to reset.

[0045] like Figure 1 and Figure 9 As shown, it also includes a pressing mechanism 9, which can automatically make the sliding rod 52 slide downward. The pressing mechanism 9 includes a horizontal plate 91, a contact rod 92 and a pressing block 93. The horizontal plate 91 is welded to the middle of the sliding rod 52, and the contact rod 92 is welded to the right side of the horizontal plate 91. The contact rod 92 is slidably connected to the mounting bracket 51. The pressing block 93 is welded to the front right side of the placement plate 3. The pressing block 93 is inclined at both the front and rear. The pressing block 93 moves backward to contact the contact rod 92.

[0046] When using the device, the placement plate 3 slides backward, causing the lower pressure block 93 to move backward. When the lower pressure block 93 moves backward and contacts the contact rod 92, the lower pressure block 93 continues to move backward, pressing the contact rod 92 downward. The downward sliding of the contact rod 92 causes the horizontal plate 91 to move downward, and the downward movement of the horizontal plate 91 causes the sliding rod 52 to slide downward, thereby causing the electric cleaning brush 54 to move downward to clean the optical lens. When the lower pressure block 93 moves backward and disengages from the contact rod 92, the sliding rod 52 slides upward to reset, and the horizontal plate 91 causes the contact rod 92 to slide upward to reset. When the test is completed, the placement plate 3 slides forward, causing the lower pressure block 93 to move forward, and then presses the contact rod 92 downward again. When the lower pressure block 93 moves forward and disengages from the contact rod 92, the contact rod 92 slides upward to reset.

[0047] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
