[0001] The application relates to the technical field of lens processing, in particular to a polishing machine for optical lens processing. BACKGROUND

[0002] In order to obtain higher surface smoothness, reduce light scattering and form accurate surface shape precision, polishing operation needs to be performed on an optical lens during processing. In the polishing operation, the optical lens is manually adsorbed on a fitting mold, the fitting mold and the lens are then placed on a polishing mold, and the center of the fitting mold is pressed by a single down rod, so that the lens and the polishing mold are tightly attached. In the process of rotating the polishing mold, the down rod drives the fitting mold and the lens to reciprocate, so as to polish the lens.

DETAILED DESCRIPTION

[0035] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of ways other than those specifically described herein, and the present application is not limited to the embodiments described herein as long as they do not depart from the scope of the present application.

[0036] As shown in Figure 1 and Figure 2 , a polishing machine for optical lens processing includes a work chamber 1, the bottom of the work chamber 1 is fixedly provided with a plurality of rotating seats 2 arranged equidistantly from left to right, the rotating seats 2 are driven to rotate by an external motor (not shown in the figure), the polishing seats 3 are installed on the rotating seats 2, as shown in Figure 2 , Figure 7 and Figure 9 , the polishing seats 3 have a concave surface, a convex surface and a plane surface.

[0037] As Figure 1 and Figure 2 shown, the rear side of the working chamber 1 is provided with a horizontal moving seat 4 corresponding to the rotating seat 2, the horizontal moving seat 4 is driven to move left and right by an external electric guide rod (not shown in the figure), the front end face of the horizontal moving seat 4 is provided with a mounting seat 5 rotating by motor two, and the mounting seat 5 is reciprocatingly rotated by motor two working.

[0038] As Figure 1 and Figure 2 shown, the mounting seat 5 is provided with a plug-in seat 6, the plug-in seat 6 is sequentially divided into an axis vertical cylindrical segment and a length direction front and rear extending rectangular segment from front to back, and the plug-in seat 6 is provided with a tooling mechanism 7 for clamping the lens and pressing the lens on the polishing seat 3.

[0039] As Figure 1 , Figure 2 and Figure 3 shown, the tooling mechanism 7 includes a clamping block 700, a plurality of circumferentially uniformly distributed hinged strips 70 are hinged on the cylindrical segment of the plug-in seat 6, the lower end of the hinged strip 70 is hinged with the clamping block 700, and the end face of the clamping block 700 towards the plug-in seat 6 is provided with a pressing block 701, and the lower end face of the pressing block 701 is adapted to the fitting process of different shape end face lenses.

[0040] The plug-in seat 6 is provided with an up and down sliding pressure column 71 penetrating through, and the lower end of the pressure column 71 is fixedly provided with an abutting plate 710.

[0041] As Figure 1 , Figure 2 and Figure 3 shown, the pressure column 71 is provided with a driving unit 72, all clamping blocks 700 clamp the lens and press the edge area of the lens by the driving unit 72, so that the axis of the pressure column 71 is collinear with the axis of the lens, and then the abutting plate 710 presses the center area of the optical lens.

[0042] When working, first, according to the need to polish the polishing mirror surface shape of the polishing lens, the corresponding polishing seat 3 and the pressing block 701 are selected, and the polishing seat 3 is installed on the rotating seat 2 and the pressing block 701 is installed on the clamping block 700, then the plug-in seat 6 is installed on the corresponding mounting seat 5, and finally the lens to be polished is manually held and placed on the polishing seat 3 (at this time the axis of the polishing seat 3 is collinear with the axis of the pressure column 71).

[0043] The driving unit 72 works, so that the pressing column 71 is lowered, and all the articulated strips 70 drive the clamping block 700 to approach the circumferential surface of the lens, and the clamping block 700 is attached to the circumferential surface of the lens, and then in the above process, the clamping block 700 drives the lower pressing block 701 to move and the lower end surface of the lower pressing block 701 presses the upper end surface of the lens, so that the axis of the lens is aligned with the axis of the pressing column 71, and the accuracy of clamping the lens is improved. After that, as the pressing column 71 gradually moves down, the lens is pressed tightly to the polishing seat 3 by the pressing plate 710, and finally the center position and the circumferential surface of the lens are subjected to the pressing force, which ensures that the lens is subjected to external pressing force during polishing, and the uniformity of the polishing is improved, which avoids the problem of affecting the final polishing effect due to uneven pressure distribution and improves the polishing accuracy of the lens surface.

[0044] As shown in Figure 2 and Figure 7 , for the case of convex mirror surface polishing and concave mirror surface polishing, the upper end surface of the polishing seat 3 is concave and convex respectively, and the external motor works to rotate the seat 2 and the polishing seat 3 synchronously, and the motor two works to drive the clamped lens to swing left and right reciprocatingly, so as to polish the lower mirror surface of the lens, as shown in Figure 9 , and for the case of polishing a plane lens, the upper end surface of the polishing seat 3 is a plane, and when polishing, the external motor one works to drive the rotating seat 2 and the polishing seat 3 to rotate synchronously, and the external motor guide works to drive the transverse seat 4 and the plane lens to move left and right reciprocatingly, so as to polish the lower mirror surface of the lens.

[0045] When the polishing operation is completed, the pressing column 71 is raised to release the clamping and pressing of the lens and the lens is taken out.

[0046] As shown in Figure 4 , in order to avoid the problem of scratching and damaging the lens due to the direct contact between the clamping block 700 and the lower pressing block 701, the end surface of the clamping block 700 and the lower end surface of the lower pressing block 701 are made of rubber material.

[0047] As shown in Figure 3 , the front end surface of the mounting seat 5 is provided with a plug-in groove 50, the plug-in seat 6 is provided with two left and right distributed butt joints 60, and the mounting seat 5 is provided with two left and right distributed plugs 61, after the plug-in seat 6 is inserted into the plug-in groove 50, the plug 61 is inserted into the corresponding butt joint 60 to lock the plug-in seat 6.

[0048] Before polishing, the installation base 5 and the pressing column 71 are assembled by inserting the installation base 5 into the insertion slot 50, and the insertion seat 6 is locked by inserting the plug 61 into the corresponding butt joint slot 60, so that the installation base 5 is locked and the axis of the pressing column 71 is collinear with the axis of the lower polishing seat 3. After clamping and locking the lens, the axis of the lens can be collinear with the axis of the pressing column 71, avoiding the situation that the convex or concave lens deviates from the center position of the polishing seat 3, and the polishing area cannot be polished according to the set shape in the subsequent reciprocating polishing process, affecting the polishing effect.

[0049] Secondly, the subsequent maintenance or replacement of the pressing block 701 is facilitated by the above-mentioned insertion and installation.

[0050] As shown in Figure 3 and Figure 4 , the lower end face of the abutting plate 710 is made of rubber, and the installation base 5 is provided with an external electric push rod, which drives the pressing column 71 and the abutting plate 710 on it to move downward synchronously.

[0051] During work, the external electric push rod works to continuously move the pressing column 71 and the abutting plate 710 downward, and the clamping block 700 is clamped around the lens by the driving unit 72. Then, as the pressing column 71 moves downward, the lens is pressed on the lower pressing seat by the abutting plate 710. At this time, it needs to be additionally pointed out that the abutting plate 710 is provided with a pressure sensor (not shown in the figure), and the force of the abutting plate 710 pressing the lens is read and fed back to the controller, and the external electric push rod is controlled to control the displacement by the controller, so as to avoid the problem that the subsequent polishing process is affected due to the excessive pressure of the abutting plate 710 on the lens. Secondly, during the polishing process of convex and concave lenses, the lens moves up and down during the left and right reciprocating movement of the installation base 5, and the external electric push rod maintains the downward pressure on the lens. That is, during this process, the lens is always in close contact with the polishing seat 3 and maintains the required downward pressure, avoiding the problem of reduced downward pressure during left and right reciprocating polishing. The above-mentioned pressure sensor and its control process are prior art, not shown in the figure and not described here.

[0052] As shown in Figure 2 , Figure 4 and Figure 5 , the driving unit 72 includes a center ring 720, the cylindrical segment of the insertion seat 6 is provided with a center ring 720 sliding up and down, the axis of the center ring 720 is collinear with the axis of the cylindrical segment of the insertion seat 6, and the circumferential surface of the center ring 720 is jointly hinged with the pressing strip 721 between the hinge strips 70.

[0053] The pressing column 71 is sequentially sleeved from top to bottom with a fixing ring 722 and a pressing ring 723, both of which are located between the insertion seat 6 and the center ring 720, and a pressing spring 724 mounted on the pressing column 71 is jointly fixed and sleeved between the fixing ring 722 and the pressing ring 723, and two front and rear distributed pressing blocks 725 are fixedly arranged on the pressing ring 723, and the inner side of the center ring 720 is fixedly provided with a corresponding pressure block 726 corresponding to the pressing block 725.

[0054] In work, the pressing column 71 continuously moves downward, driving the fixing ring 722 and the pressing ring 723 to move downward synchronously, before the abutting plate 710 contacts the mirror surface, the pressing ring 723 drives the pressing block 725 thereon to gradually move downward and contact the pressure block 726, and as the pressing column 71 drives the fixing ring 722 to gradually move downward, the pressing spring 724 is deformed, and the elastic force generated by the deformation of the pressing spring 724 acts on the pressure block 726 through the pressing block 725, so that the center ring 720 has a downward force along the length direction of the pressing strip 721 on the corresponding hinged strip 70 through the pressing strip 721, and the force acting on the hinged strip 70 can be divided into a first component force horizontally and pointing to the pressing column 71 and a second component force vertically downward, wherein the first component force drives the hinged strip 70 to synchronously approach the corresponding clamping block 700, and the second component force drives the hinged strip 70 to have a downward pressing force on the lens through the clamping block 700 and the lower pressing block 701 adhering to the lens, thus the mutual approach of all clamping blocks 700 makes the lens axis and the pressing column 71 axis collinear, and the lower pressing block 701 has a downward pressure on the lens edge, and it needs to be supplemented that in the above process, as the clamping block 700 approaches and adheres to the mirror surface, the lower end of the hinged strip 70 has a tendency to approach the pressing column 71, but as the lower pressing block 701 presses and contacts the mirror surface, the clamping block 700 is limited to avoid the problem of the clamping block 700 separating from the circumferential surface of the lens, and in summary, in the process of the center ring 720 moving downward, the clamping block 700 can abut against the circumferential surface of the lens and the lower pressing block 701 can press the lens.

[0055] As shown in Figure 5 The pressing column 71 is sequentially sleeved from top to bottom with a fixing ring 722 and a pressing ring 723, both of which are located between the insertion seat 6 and the center ring 720, and a pressing spring 724 mounted on the pressing column 71 is jointly fixed and sleeved between the fixing ring 722 and the pressing ring 723, and two front and rear distributed pressing blocks 725 are fixedly arranged on the pressing ring 723, and the inner side of the center ring 720 is fixedly provided with a corresponding pressure block 726 corresponding to the pressing block 725.

[0056] By fixing the fixing ring 722 to different heights, the abutting plate 710 can adapt to convex mirror surface, concave mirror surface and plane mirror surface.

[0057] Before clamping and polishing, according to the shape (concave, convex or flat) and the shape characteristic specification (such as the concave depth of the concave or the convex height of the convex) of the required polishing mirror surface, the corresponding through groove 727 is selected, and the fixing ring 722 is moved so that the fixing ring 722 is opposite to the through groove 727, and then the locking pin 728 is inserted into the corresponding through groove 727, and thus the fixing ring 722 is locked to the set position, so that when the abutting plate 710 is attached to the abutting mirror surface, the deformation amount of the pressure spring 724 at this time is changed by changing the up-down position of the fixing ring 722, thereby controlling the pressure size of the elastic force distributed on the edge of the mirror surface by the deformation of the pressure spring 724, ensuring that the pressure distribution is uniform and the pressure value meets the required pressure during polishing, and avoiding the problem that the polishing effect of the lens is affected due to excessive pressure.

[0058] As shown in Figure 6 , Figure 8 and Figure 10 , the clamping block 700 is provided with a clamping groove 702 on one side of the end face of the pressing column 71 in the circumferential direction, and the lower pressing block 701 is fixedly provided with a clamping block 703, and the clamping installation of the lower pressing block 701 is completed by clamping the clamping block 703 into the corresponding clamping groove 702.

[0059] By the installation mode between the lower pressing block 701 and the clamping block 700, different shapes of the lower pressing block 701 are replaced to adapt to the abutting requirements of convex mirror surface, concave mirror surface and flat mirror surface respectively.

[0060] As shown in Figure 6 , Figure 8 and Figure 10 , the lower end face of the lower pressing block 701 adapted to the convex mirror surface is concave, the lower end face of the lower pressing block 701 adapted to the flat mirror surface is flat, and the lower end face of the lower pressing block 701 adapted to the concave mirror surface is convex. By replacing different lower pressing blocks 701 to adapt to convex, concave and flat tool clamping, the driving unit 72 makes the lens be centered and clamped, the lower pressing block 701 presses the lens at the edge position of the lens, and the abutting plate 710 presses the lens at the center position of the lens, and the lens is uniformly pressed in a conical shape at the center position of the lens and the circumferential edge position.

[0061] Before polishing, according to the upper side mirror surface characteristics of the lens to be polished, the corresponding lower pressing block 701 is selected, and before clamping and polishing the lens, the corresponding lower pressing block 701 is installed on the corresponding clamping block 700 by inserting the clamping block 703 into the clamping groove 702, and thus the above-mentioned mode is adapted to different mirror polishing requirements, and the plug-in installation mode improves the universality and convenience in the operation process.

[0062] As shown in Figure 5As shown, in order to make the clamping block 700 present a vertical orientation to facilitate the fitting of the lens before the clamping block 700 abuts against the lens, the elastic rope 704 is fixed between the hinge strip 70 and the clamping block 700.

[0063] It needs to be additionally explained that, compared with the polishing technical solution in the prior art, in the present application, the multiple clamping blocks 700 and the pressing block 701 are added to adjust the position of the lens so that the central region of the lens is located directly below the abutting plate 710 before the abutting plate 710 abuts against the central region of the lens, and when the abutting plate 710 abuts against the central region of the lens, the lens is clamped in the circumferential direction by the clamping block 700, thereby improving the stability during polishing. In addition, the pressing block 701 exerts a downward pressing force on the edge region of the lens. In summary, downward pressure is exerted on the central region and the edge region of the lens during polishing, which ensures that the lens is uniformly stressed during polishing and avoids the situation that uneven pressure leads to different material removal rates in different parts of the lens, thereby affecting the polishing uniformity. In addition, the clamping block 700, the pressing block 701 and the driving unit 72 added in the present technical solution are all conventional mechanical components, which can be used multiple times after single installation, and therefore have low cost. At the same time, compared with the economic benefits brought by improving the polishing uniformity of the lens during polishing, the above-mentioned increased cost can be ignored, so that the present technical solution is a specific improvement based on the existing technical conditions and solving the problems of the prior art.

[0065] In addition, the terms "first", "second", "one", "two" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", "one", "two" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise specifically limited.
