Description

Technical Field

[0001] This utility model specifically relates to an auxiliary device for cutting the edge of a high-refractive-index lens. Background Technology

[0002] High-refractive-index lenses are optical lenses with a higher refractive index than ordinary lenses. They are commonly used in eyeglass manufacturing to meet different refractive errors and wearing needs.

[0003] Currently, after the production of high-refractive-index lenses, their outer edges need to be cut, while the middle part that is to be used is retained. However, during the cutting process, it is also necessary to guide the cutting direction, otherwise cutting deviations will occur, affecting the subsequent use of high-refractive-index lenses. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for cutting the edge of a high-refractive-index lens, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for cutting edges of high-refractive-index lenses, comprising a base, two movable frames, and a marking guide assembly. The high-refractive-index lens is placed on the surface of the base, and a crossbeam is provided between the two movable frames. The marking guide assembly is slidably disposed on the crossbeam. The marking guide assembly includes a movable shell sleeved on the crossbeam, a lifting block is slidably disposed at the head of the movable shell, and a marking wheel is disposed vertically below the lifting block.

[0006] Preferably, the base has sliding grooves at both ends, and the movable frame has a connecting column at its vertical lower end. A roller adapted to the sliding groove is inserted into the connecting column, and the roller extends into the sliding groove.

[0007] Preferably, the surface of the movable frame is provided with a slot for inserting the crossbeam, and the movable frame is provided with an adjustment component for controlling the height of the crossbeam in the slot.

[0008] Preferably, the adjustment assembly includes two protruding plates disposed on the outside of the movable frame, with bolts inserted into the protruding plates and the bolts passing through the crossbeam.

[0009] Preferably, the marking guide assembly further includes a fixed base centrally disposed on the movable housing, and a handle is hinged to the fixed base.

[0010] Preferably, the movable shell head has matching slide rails on both sides and the surface of the lifting block, the upper surface of the lifting block has a downward recessed pressing groove, and the handle extends outward toward the pressing groove to a pressing part.

[0011] Preferably, a spring is provided inside the lifting block, and the other end of the spring is connected to the upper surface of the moving shell head.

[0012] The technical effects and advantages of this utility model are as follows: This auxiliary device for trimming high-refractive-index lenses places the high-refractive-index lens to be trimmed on the base surface. After determining the desired trimming position based on the lens surface, the moving frame is pushed. As the roller slides along the length of the slide groove, two moving frames follow, moving the crossbeam to the desired trimming position. The bolt is tightened to adjust the position of the crossbeam in the slot, allowing the marking wheel to contact the lens surface when pressed. Pressing the handle lowers the pressing part and applies pressure to the pressing groove. Guided by the slide rail, the lifting block descends, allowing the marking wheel to contact the lens. With the movement of the moving housing, a mark can be made on the lens surface, improving the convenience of subsequent trimming and increasing work efficiency. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] To facilitate marking of the lenses to be cut, refer to Figure 1 , Figure 2 and Figure 3As shown, the system includes a base 1, two movable frames 2, and a marking guide assembly. A high-refractive-index lens is placed on the surface of the base 1. A crossbeam 3 is provided between the two movable frames 2. The marking guide assembly is slidably mounted on the crossbeam 3. The marking guide assembly includes a movable shell 4 sleeved on the crossbeam 3. A lifting block 5 is slidably mounted on the head of the movable shell 4. A marking wheel 6 is vertically positioned below the lifting block 5. The high-refractive-index lens to be cut is placed on the surface of the base 1. After determining the desired cutting position based on the lens surface, the movable frames 2 are pushed, and the roller 9 moves along the groove. The slide 7 slides along the length of the slide groove 7, causing the two movable frames 2 to move accordingly, and causing the crossbeam 3 to move to the required cutting position. Tighten the bolt 11 to adjust the position of the crossbeam 3 in the slot so that the marking wheel 6 can contact the lens surface when pressed. As the handle 13 is pressed, the pressing part 15 is lowered and pressure is applied to the pressing groove 14. Under the guidance of the slide rail, the lifting block 5 is lowered so that the marking wheel 6 can contact the lens. With the movement of the movable shell 4, marking can be made on the lens surface to improve the convenience of subsequent cutting.

[0022] For easy adjustment of the height of marker wheel 6, refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the base 1 has grooves 7 at both ends. The movable frame 2 has a connecting column 8 vertically below it. A roller 9 adapted to the groove 7 is inserted into the connecting column 8. The roller 9 extends into the groove 7. As the roller 9 slides along the length of the groove 7, it drives the crossbeam 3 to move, causing the marking wheel 6 to move laterally to the position where the lens needs to be marked. The movable frame 2 has slots for the crossbeam 3 to be inserted. The movable frame 2 is equipped with an adjustment component for controlling the height of the crossbeam 3 in the slot. The adjustment component includes two protruding plates 10 on the outside of the movable frame 2. Bolts 11 are inserted into the protruding plates 10 and pass through the crossbeam 3. The crossbeam 3 has screw holes adapted to the bolts 11. The bolts 11 are arranged in two mirror images. By turning the bolts 11, the position of the crossbeam 3 in the slot can be adjusted according to the distance between the marking wheel 6 and the lens. The marking guide assembly also includes a fixed base 12 centrally located on the movable housing 4, with a handle 13 hinged to the fixed base 12. The movable housing 4 has matching slide rails on both sides of its head and the surface of the lifting block 5. The upper surface of the lifting block 5 has a downwardly recessed pressing groove 14. The handle 13 extends outward towards the pressing groove 14 to a pressing part 15. When the handle 13 is pressed, the pressing part 15 descends towards the pressing groove 14, providing pressure to the pressing groove 14. As the slide rails slide, the lifting block 5 descends at the head of the movable housing 4, causing the marking wheel 6 to descend and come into contact with the lens. Simultaneously, the lifting block 5 lowers, stretching the spring 16. After marking is completed, releasing the handle 13 causes the spring 16 to deform, allowing the lifting block 5 to rise, thus raising the marking wheel 6. A spring 16 is installed inside the lifting block 5, with the other end of the spring 16 connected to the upper surface of the head of the movable housing 4.

[0023] In use, first place the high-refractive-index lens to be cut on the surface of the base 1. After determining the desired cutting position by observing the lens surface, push the moving frame 2. As the roller 9 slides along the length of the slide groove 7, the two moving frames 2 move accordingly, moving the crossbeam 3 to the desired cutting position. Tighten the bolt 11 to adjust the position of the crossbeam 3 in the slot so that the marking wheel 6 can contact the lens surface when pressed. Press the handle 13 to lower the pressing part 15 and apply pressure to the pressing groove 14. Guided by the slide rail, the lifting block 5 lowers so that the marking wheel 6 can contact the lens. With the movement of the moving shell 4, marking can be made on the lens surface.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
