Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass coating technology, and in particular to an optical glass coating fixture. Background Technology
[0002] Optical glass refers to glass materials specifically used in the field of optics, which possess specific optical properties through precise control of their composition and manufacturing process. Optical glass coating refers to the process of depositing metal or dielectric thin films on both sides of optical glass, with the aim of changing the reflection, transmission, polarization and other characteristics of light, thereby improving optical performance.
[0003] In the process of optical glass coating, a clamping structure is needed to hold and fix the glass. For example, Chinese Patent Publication No. CN216585217U discloses an optical glass coating fixture, including a base plate with pneumatic clamping mechanisms symmetrically arranged on both sides. The pneumatic clamping mechanism includes a housing, a longitudinal slider, a transverse slider, and elastic clamping arms. Pneumatic clamping structures and elastic elements are respectively provided on both sides inside the housing. The longitudinal and transverse sliders are slidably disposed within the housing, and the elastic clamping arms are rotatably connected to the longitudinal and transverse sliders respectively. One end of the longitudinal slider is connected to the elastic element, and the other end is in contact with the pneumatic clamping structure. This utility model has a simple structure. Compared with existing fixtures, it is not only more compact in size but also easier to disassemble and assemble, allowing operators to quickly complete related maintenance work. Because it uses pneumatic clamping to control the opening and closing of the elastic clamping arms, it is more stable and has a better clamping effect when clamping workpieces.
[0004] In actual operation, the elastic clamping arm can be replaced with different specifications of elastic clamping arms that are compatible with the glass size by disassembling the elastic clamping arm and the housing. However, the elastic clamping arm is connected to the slider and the housing by a pin, which lacks a structure that facilitates replacement, affecting the replacement efficiency and making it less practical. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of assembling and disassembling the elastic clamping arms, by proposing an optical glass coating clamp.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design an optical glass coating fixture, installed in the machine body, including a flipping mechanism and a set of clamping mechanisms. The set of clamping mechanisms cooperate with each other to clamp the glass from the side, and the set of clamping mechanisms flips the glass through the flipping mechanism.
[0008] The clamping mechanism includes a bracket and two clamps, which are detachably connected to the bracket via a connecting structure.
[0009] Furthermore, the flipping mechanism includes a slide rail, and a pair of support frames are slidably connected to the top of the slide rail via a drive unit. A rotating seat is rotatably connected to the top of each pair of support frames. A motor is also fixedly connected to the side wall of one of the support frames, and the output end of the motor is fixedly connected to the end of the rotating seat.
[0010] Furthermore, a group of the brackets are arranged opposite to each other and are respectively fixedly connected to the ends of the rotating seats on adjacent sides. The clamp extends outward from the end near the bracket, and at least two connecting rods are provided at the bottom of the extended end of the clamp. The clamp is movably inserted into the bracket through the connecting rods.
[0011] Furthermore, the connecting structure includes a protrusion, at least one of the free ends of the connecting rod is provided with the protrusion, the protrusion extends downward along the centerline to form a deformation groove, the protrusion passes through the deformation groove and abuts against the bracket.
[0012] Furthermore, a set of the clamps are arranged in a symmetrical structure, and a recess is provided on the inner side of the clamp along the length direction. The inner wall of the recess is provided with an anti-slip pad, and the side of the glass is engaged in the recess and pressed against the anti-slip pad.
[0013] Furthermore, all of the clamping mechanisms described in the group have the same structure and are set at the same height.
[0014] The advantages of this invention are as follows: A pair of support frames are provided on the slide rail. These support frames can be moved relative to each other via a drive unit to drive a set of clamps to clamp the glass from the side. After the coating on one side of the glass solidifies, the glass is flipped over by a motor-driven rotating seat and a set of clamps, facilitating the coating operation on the other side. Furthermore, the clamps and supports can be easily disassembled and reassembled via a connecting structure. By replacing clamps of different specifications to match the glass size, the clamps can clamp and fix glass of different sizes within a certain range. The structure is simple and highly practical.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5 An optical glass coating fixture is installed in a body 1, including a flipping mechanism 2 and a set of clamping mechanisms 3. The set of clamping mechanisms 3 cooperate with each other to clamp the glass on the side, and the set of clamping mechanisms 3 flips the glass through the flipping mechanism 2.
[0023] The clamping mechanism 3 includes a bracket 31 and two clamps 32, which are detachably connected to the bracket 31 via a connecting structure 4.
[0024] It should be added that after the lens is fixed by a set of clamps 32, the glass surface is in full contact with the reagent. After the coating on one side of the glass solidifies, the set of clamps 32, together with the flipping mechanism 2, drives the glass to flip so as to coat the other side. The coating method is existing technology and will not be described in detail here.
[0025] Furthermore, the flipping mechanism 2 includes a slide rail 21, and a pair of support frames 22 are slidably connected to the top of the slide rail 21 via a drive unit. The top of each pair of support frames 22 is rotatably connected to a rotating seat 23. A motor 24 is also fixedly connected to the side wall of one of the support frames 22, and the output end of the motor 24 is fixedly connected to the end of the rotating seat 23.
[0026] In some embodiments, the drive unit may be a dual-axis lead screw and a drive motor. A pair of support frames 22 are threadedly connected to both ends of the dual-axis lead screw, and the drive motor is fixedly connected to the side of the slide rail 21. The output end of the drive motor is fixedly connected to one end of the dual-axis lead screw, thereby driving the pair of support frames 22 to move relative to each other.
[0027] Furthermore, after a set of clamps 32 clamps the glass from the side, the clamping force of the clamps 32 and the recessed part 322 and the anti-slip pad further increase the friction between the glass and the clamps 32. Then, by driving a motor 24, the glass can be flipped in conjunction with a pair of rotating seats 23 to realize the glass coating operation.
[0028] Furthermore, a set of brackets 31 are arranged opposite to each other and are respectively fixedly connected to the ends of the rotating seats 23 on the adjacent side. The clamp 32 extends outward from the end near the bracket 31. At least two connecting rods 321 are provided at the bottom of the extended end of the clamp 32. The clamp 32 is movably inserted into the bracket 31 through the connecting rods 321.
[0029] More specifically, the connecting structure 4 includes a protrusion 41, at least one of the free ends of the connecting rod 321 is provided with the protrusion 41, the protrusion 41 extends downward along the centerline to form a deformation groove 42, the protrusion 41 passes through the deformation groove 42 and abuts against the bracket 31.
[0030] In this embodiment, at least a pair of connecting rods 321 are fixedly connected to the bottom of one extended end of the clamp 32. The clamp 32 is circumferentially locked by the pair of connecting rods 321 to prevent the clamp 32 from rotating freely.
[0031] Furthermore, the connecting rod 321 is preferably made of a material with deformation capability such as rubber or plastic. The through hole on the bracket 31 corresponding to the protrusion 41 has a straight groove structure. The end of the protrusion 41 is provided with a guide slope. The guide slope is used to reduce the friction force generated when the protrusion 41 and the bracket 31 come into contact.
[0032] Furthermore, when the protrusion 41 comes into contact with the straight groove, it deforms through the deformation groove 42 to avoid the straight groove, and after restoring its deformation, the protrusion 41 comes into contact with the side wall of the bracket 31, thereby achieving the function of fixing the clamp 32.
[0033] It is worth mentioning that the set of clamps 32 in this embodiment is more suitable for side clamping of glass with a circular structure. Considering that different sizes of glass require a set of clamps 32 with matching specifications, the clamps 32 and the bracket 31 are detachably connected, which facilitates assembly on the one hand and easy replacement of clamps 32 that are compatible with the glass on the other.
[0034] In general, a set of clamps 32 are symmetrically arranged when closed, and a recess 322 is provided on the inner side of the clamp 32 along the length direction. The inner wall of the recess 322 is provided with an anti-slip pad, and the side of the glass is engaged in the recess 322 and abuts against the anti-slip pad.
[0035] Specifically, the glass sidewall is engaged in the recess 322 of a set of clamps 32, and the anti-slip pads allow the clamps 32 to better fit against the glass sidewall under the clamping force, further improving the clamping tightness.
[0036] Finally, all of the clamping mechanisms 3 described in the group have the same structure and are set at the same height.
[0037] Working method: During operation, the glass is placed between a set of clamping mechanisms 3. A pair of support frames 22 move relative to each other under the action of the drive unit. The two clamps 32 on both sides clamp the glass on the side through the recessed part 322 and the anti-slip soft pad, so that the coating unit can be used to coat one side of the glass.
[0038] After the glass surface coating cools down, the motor 24 drives one of the rotating seats 23 to rotate. The pair of rotating seats 23 work together to flip the glass over, and then the other side of the glass can be coated.
[0039] Finally, the clamp 32 can be disassembled and replaced to adapt to different sizes of glass within a certain range. At the same time, after pressing the protrusion 41 to retract and disengage from the through hole, the clamp 32 can be replaced. Similarly, when the protrusion 41 passes through the through hole through the deformation groove 42 and recovers its deformation, the protrusion 41 abuts against the side wall of the bracket 31, and the clamp 32 can be fixed.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
