Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, and specifically discloses a cutting device for optical lens processing. Background Technology

[0002] Lenses are transparent materials with one or more curved surfaces, made of optical materials such as glass or resin. Among them, optical lenses, as a type of lens made of optical glass or resin, are characterized by their good scratch resistance and high refractive index. ， Widely used in fields such as biology, electronics, and chemical engineering, cutting is a crucial process in the production of optical lenses. This is especially true for products like 1.67 high-refractive-index polarizing lenses and 1.61 lenses, which require extremely high optical performance and processing precision. During the production of optical lenses, cylindrical optical glass needs to be cut into the required shapes.

[0003] Existing optical lens cutting devices require fixing the cylindrical optical glass before cutting the other end to obtain the desired optical lens. However, these devices can only cut one lens at a time, requiring multiple cuts to complete the process. This results in low cutting efficiency. Furthermore, the cutting process necessitates repeated adjustments to the device's position to progressively cut the cylindrical optical glass, which is cumbersome and inconvenient.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-4 A cutting device for optical lens processing includes a housing 1, and a cutting mechanism is provided inside the housing 1.

[0024] The cutting mechanism includes a support plate 2 fixedly connected inside the box 1. A support platform 3 is fixedly connected to the upper end of the support plate 2. A placement groove 4 is opened on the upper end of the support platform 3. Multiple evenly distributed wire passage grooves 5 with open structures at both the front and rear ends are opened on the upper end of the support platform 3. A limit mechanism and a spraying mechanism are provided on the upper end of the support plate 2.

[0025] The cutting mechanism also includes a mounting plate 6 located below the support plate 2. A multi-stage electric telescopic rod 7 is installed on the lower end face of the housing 1. The output end of the multi-stage electric telescopic rod 7 is fixedly connected to the lower end face of the mounting plate 6. A number of evenly distributed vertical plates 8 are fixedly connected to the upper end face of the mounting plate 6, located on the front and rear sides of the support plate 2 respectively. The multiple vertical plates 8 are grouped in pairs, and each group of vertical plates 8 is rotatably connected to two vertically distributed rotating shafts 9. One of the rotating shafts 9 is driven by a drive motor 10 installed on the outer wall of one of the vertical plates 8. A number of evenly distributed rollers 11 are fixedly connected to the outer walls of the four rotating shafts 9. The multiple rollers 11 located in the same vertical plane are grouped in four, and each group of rollers 11 is connected to a cutting steel wire 12.

[0026] In this embodiment: When in use, the cylindrical optical glass is placed in the placement groove 4 and limited by the limiting mechanism to prevent the cylindrical optical glass from shifting during the cutting process. Then, the cylindrical optical glass is cut by the cutting mechanism.

[0027] Specifically, the multi-stage electric telescopic rod 7 retracts, causing the mounting plate 6 to move downwards. The mounting plate 6, in conjunction with multiple vertical plates 8, drives multiple rotating shafts 9 and multiple rollers 11 to move downwards. The multiple rollers 11 drive multiple cutting steel wires 12 downwards, bringing the cutting steel wires 12 closer to the cylindrical optical glass. Simultaneously, the drive motor 10 starts, driving one of the rotating shafts 9 to rotate. This rotating shaft 9, in conjunction with multiple rotating shafts 9, drives multiple rollers 11 to rotate. The multiple rollers 11, in conjunction with the multiple cutting steel wires 12, drive the other multiple rotating shafts 9 and multiple rollers 11 to rotate. The roller 11 rotates, and then the multiple cutting steel wires 12 that move downward and rotate cut the cylindrical optical glass, thereby cutting the cylindrical optical glass in one go, effectively improving the cutting efficiency of optical lenses. During the cutting process, cutting fluid is sprayed onto the cutting point by a spraying mechanism. The cutting fluid cools the cylindrical optical glass and the cutting steel wires 12, so that the cutting steel wires 12 can cut the cylindrical optical glass stably. At the same time, by cutting the cylindrical optical glass in one go, there is no need to adjust the position of the cutting mechanism, which is convenient to use.

[0028] Multiple cutting steel wires 12 cut the cylindrical optical glass and move downwards to near the support platform 3. The multiple cutting steel wires 12 enter multiple wire grooves 5 respectively to prevent the support platform 3 from affecting the movement of the cutting steel wires 12 when they are cutting the cylindrical optical glass.

[0029] As a technical optimization of this utility model, the limiting mechanism includes limiting plates 13 fixedly connected to the upper end face of the support plate 2 and located on the left and right sides of the support platform 3. Each of the two limiting plates 13 has a screw 14 threadedly connected to one side wall facing away from each other. Each of the two screws 14 has an abutment plate 15 rotatably connected to one end facing away from each other. The center of the two abutment plates 15 and the center of the placement groove 4 are on the same straight line.

[0030] In this embodiment: when limiting the cylindrical optical glass, the two screws 14 are rotated by the torsion block. The two screws 14 respectively drive the two abutment plates 15 to move in opposite directions, so that the two abutment plates 15 abut against the two ends of the cylindrical optical glass, thereby limiting the cylindrical optical glass by the two abutment plates 15.

[0031] As a technical optimization of this utility model, the spraying mechanism includes a cavity 16 opened inside the limiting plate 13. Two nozzles 17 communicating with the cavity 16 are fixedly connected to one side wall of each of the two limiting plates 13. The lower end face of the support plate 2 is fixedly connected to pipes 18 communicating with the two cavities 16 respectively. The other end of each of the two pipes 18 extends to the lower end of the inner part of the box 1 and is equipped with a water pump 19 with a filter mechanism.

[0032] In this embodiment: During the cutting process, two water pumps 19 are started, and the two water pumps 19 deliver the cutting fluid to the cavity 16 through two pipes 18. Then, the cutting fluid is sprayed to the cutting point through multiple nozzles 17.

[0033] As a technical optimization of this utility model, tension rollers 20 located between multiple rotating shafts 9 are rotatably connected between the two sets of vertical plates 8.

[0034] In this embodiment, the cutting steel wire 12 can be tensioned by two tensioning rollers 20, so that the wrap angle between the cutting steel wire 12 and the multiple rollers 11 is greater than 120 degrees, and the multiple rollers 11 can effectively drive the cutting steel wire 12.

[0035] As a technical optimization of this utility model, a plurality of evenly distributed slide rods 21 are fixedly connected between the lower end of the inner side of the housing 1 and the lower end face of the support plate 2, and are slidably connected to the mounting plate 6.

[0036] In this embodiment, the mounting plate 6 can be limited by multiple sliding rods 21, so that the mounting plate 6 can move smoothly.

[0037] As a technical optimization of this utility model, both the left and right side walls of the box body 1 are equipped with box doors 22.

[0038] In this embodiment, the two door 22 facilitate the placement of cylindrical optical glass, the retrieval of cut optical lenses, and the positioning of the cylindrical optical glass.

[0039] As a technical optimization of this utility model, an observation window 23 is provided through the front end face of the box 1, and a protective glass is fixedly connected inside the observation window 23.

[0040] In this embodiment: the observation window 23 facilitates the observation of the cutting process of the cylindrical optical glass, and the protective glass can block the observation window 23.

[0041] The working principle and usage process of this utility model are as follows: When in use, the cylindrical optical glass is placed in the placement groove 4, and then the two screws 14 are rotated by the torsion block. The two screws 14 drive the two abutment plates 15 to move in opposite directions, so that the two abutment plates 15 abut against the two ends of the cylindrical optical glass. The two abutment plates 15 limit the cylindrical optical glass and prevent it from shifting during the cutting process. Then, the cylindrical optical glass is cut by the cutting mechanism.

[0042] Specifically, the multi-stage electric telescopic rod 7 retracts, causing the mounting plate 6 to move downwards. The mounting plate 6, in conjunction with multiple vertical plates 8, drives multiple rotating shafts 9 and multiple rollers 11 to move downwards. The multiple rollers 11 drive multiple cutting steel wires 12 downwards, bringing the cutting steel wires 12 closer to the cylindrical optical glass. Simultaneously, the drive motor 10 starts, driving one of the rotating shafts 9 to rotate. This rotating shaft 9, in conjunction with multiple rotating shafts 9, drives multiple rollers 11 to rotate. The multiple rollers 11, in conjunction with the multiple cutting steel wires 12, drive other multiple rotating shafts 9 and multiple rollers 11 to rotate. Thus, the downward-moving and rotating multiple cutting steel wires 12 cut the cylindrical optical glass. During the cutting process, two water pumps 19 are started, and the two water pumps 19 deliver cutting fluid to the cavity 16 through two pipes 18. Then, the cutting fluid is sprayed onto the cutting point through multiple nozzles 17. The cutting fluid cools the cylindrical optical glass and the cutting steel wires 12, allowing the cutting steel wires 12 to stably cut the cylindrical optical glass.
