Description

[0002] In the optical technology field, the centering process of optical lens has extremely important role, manual lens centering operation is carried out in prior art, and it is very important to use centering instrument to adjust the concentricity of upper lens and lower lens in the centering process of glued lens. Generally, after adjusting the height of microscope to the appropriate distance and the reference, the upper lens and the lower lens are glued, and the glued lens after air bubble is discharged is placed on the fixture under the centering instrument, the lower lens in the glued lens on the fixture load position is fixed by thumb and index finger, then the crosshair on the display is observed under microscope to determine whether it moves to the reference point position, and the process is the centering process of glued lens. When the crosshair point position is moved, the centering is completed, and the UV lamp is turned on by foot to fix the upper and lower lenses. This process needs to be repeated manually to adjust the concentricity of upper lens and lower lens, and the force applied to the upper lens by the needle fixture held by hand needs to be carefully controlled when the upper lens is slightly adjusted, and the force is too large to cause the special glue used between the upper lens and the lower lens to overflow or cause appearance defect, thereby increasing the defect rate and affecting the production efficiency, which is time-consuming and labor-intensive. Not only slow and high cost, but also ultraviolet light irradiation for a long time is harmful to human body. Manual operation is subjective and has high error rate, which makes the consistency of products poor and the degree of automation low.
[0003] Now some centering devices appear on the market, which can complete centering, but when different models are replaced, the size of glued lens is different, which makes the machine adjustment too complicated.

In the centering process, the concentricity of glued lens is frequently deviated due to external factors. In view of the above problems, it is necessary to study a concentric device for optical lens.

[0024] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.
[0025] Embodiment 1
[0026] Figure 2 As shown, the concentric device 2 provided by the embodiment comprises a centering base 109, the centering base 109 is provided with a first precision displacement table 103, the first precision displacement table 103 is provided with a centering bottom plate 100, the centering bottom plate 100 is vertically provided with a centering side plate 83, the centering side plate 83 is provided with a centering mechanism and a precision motion assembly 123, and the precision motion assembly 123 can drive the centering mechanism to move up and down.
[0027] Further comprising a height assembly 122, the height assembly 122 comprises a first micro differential cylinder 110 and a first air cylinder 111, the first micro differential cylinder 110 is installed on the centering mechanism, the first air cylinder 111 is installed on the centering bottom plate 100, and the extension end of the first air cylinder 111 is installed with a detector 106; when the centering mechanism moves downward, the measuring rod of the first micro differential cylinder 110 can contact the detector 106, the detector 106 can detect the pressure of the centering mechanism on the upper and lower lenses of the glued lenses, and the first micro differential cylinder 110 can adjust the pressure of the centering mechanism on the upper and lower lenses of the glued lenses by adjusting the extension length of the measuring rod.
[0028] Further comprising a side fixing block 105, one end of the side fixing block 105 is fixed on the extension end of the first air cylinder 111, and the other side is freely inserted into the centering bottom plate 100, the detector 106 is installed on the side fixing block 105 and located directly above the extension end of the first air cylinder 111; when the measuring rod of the first micro differential cylinder 110 presses the detector 106 downward, the extension end of the first air cylinder 111 drives the side fixing block 105 to move downward, and the side fixing block 105 prevents the extension end of the first air cylinder 111 from rotating.
[0029] The centering mechanism is fixedly installed with a lifting plate 82, which is arranged on the precise motion assembly 123. The precise motion assembly 123 can block the downward movement of the centering mechanism under the action of gravity through the lifting plate 82, and can drive the upward movement of the centering mechanism through the lifting plate 82. In this embodiment, the precise motion assembly 123 is a cylinder lifting structure. Specifically, as shown in Figure 2 The second cylinder 85 is fixedly installed on the fixed support 80, which is fixedly installed on the centering side plate 83. The lifting plate 82 is arranged on the top of the extending end of the cylinder lifting structure. It can be considered that a jacking column is installed on the top of the extending end of the cylinder lifting structure. At this time, the reserved circular hole on the lifting plate 82 penetrates and is overlapped on the jacking column. When the extending end of the second cylinder 85 extends, it can drive the lifting plate 82 to move upward. The reserved circular hole cooperates with the jacking column to stabilize the lifting plate 82. When the extending end of the second cylinder 85 retracts, the centering mechanism slides downward along the centering side plate 83 under the action of gravity. When the extending end of the second cylinder 85 extends, it drives the lifting plate 82 to move upward, so that the centering mechanism moves upward. In order to prevent the centering mechanism from being pulled out of the centering side plate 83 when moving upward, it can be considered that the left fixed block 81 is fixedly installed on the top end of the centering side plate 83, which limits the centering mechanism.
[0030] Specifically, the centering mechanism includes a guide rail slider 98, which is fixedly installed on the centering side plate 83. The guide rail slider 98 is slidably installed with a lifting fixed block 88. The lifting fixed block 88 is fixedly installed with a centering fixed block 91. The centering fixed block 91 is installed with a horizontal plate 89. The front end of the horizontal plate 89 is installed with a centering cover 90. In order to better ensure the horizontal stability of the horizontal plate 89 during the centering process, at least one pair of baffles can be considered on the front surface of the lifting fixed block 88. The centering fixed block 91 is fixedly installed on the front surface of the lifting fixed block 88, and the centering fixed block 91 is limited by the baffles.
[0031] In order to increase the stability of the centering mechanism, a centering support plate 95 can be considered, which is fixedly installed on the back of the centering side plate 83, and the centering support plate 95 is fixedly connected with the centering bottom plate 100.
[0032] It should be noted that the first precise displacement table 103 is a two-dimensional platform, which can use existing products, and can move in X and Y directions to more accurately adjust the concentricity of the lower lens and the upper lens of the glued lens.
[0033] As Figure 1 , 2As shown, in actual operation, when the centering mechanism moves downward, the measuring rod of the first differential cylinder 110 can contact the detector 106. The detector 106 can detect the pressure applied by the centering mechanism to the upper and lower lenses of the bonded lens. When different products (bonded lenses) are replaced, the height component 122 is adjusted according to the height (thickness) difference before and after the replacement, which can more accurately control the position of the centering cover 90 contacting the lower and upper lenses of the bonded film on the loading position of the fixture. The detector, together with the height component 122, more accurately controls the pressure applied by the centering cover 90 to the lower and upper lenses of the bonded film on the loading position of the fixture, which is consistent with the pressure applied by the centering mechanism to the upper and lower lenses of the bonded lens before and after the replacement of different products (bonded lenses), effectively avoiding glue overflow and poor appearance.
[0034] Example 2
[0035] In this embodiment, the precision motion component can adopt a lead screw structure, and the lifting plate 82 overlaps on the upper surface of the lead screw fixing block 86 of the lead screw structure. Other structures are the same as in Embodiment 1.
[0036] Specifically, such as Figure 3 As shown, in this embodiment, the precision motion component 123 is disposed on the right side of the centering side plate 83. The precision motion component 123 includes a lead screw nut 130, which is disposed on a lead screw fixing block 86. The lead screw fixing block 86 is sleeved on the guide rail rod 96 and the lead screw 85. One end of the guide rail rod 96 is fixed on the left fixed bracket 80, and the other end of the guide rail rod 96 is fixed on the right fixed bracket 99. Bearings are provided in the left fixed bracket 80 and the right fixed bracket 99 to fix the lead screw 85. One end of the lead screw 85 extends out and is connected to the motor 108 through the coupling 101. The motor 108 is disposed on the motor fixing seat 102, which is disposed on the centering side plate 83. The precision motion component 123 can respond faster to achieve fast and slow up and down movement and more precise position positioning, and better match the up and down displacement position of the centering cover 90.
