Description

Technical Field

[0001] This utility model belongs to the technical field of lens coating equipment, specifically relating to an automatic lens coating machine. Background Technology

[0002] Resin lens blanks are processed in the workshop through thinning, grinding, and polishing to become finished lenses ready for assembly. During this process, to prevent damage to the non-processed surfaces, a protective film is applied to them. In existing technologies, traditional film application is mostly done manually. The film is applied manually, and after application, the lens is manually cut. This process is time-consuming, inefficient, and the quality of the application cannot be guaranteed. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing an automatic lens coating machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatic lens film applicator, comprising a film conveying structure on which a film component is installed, a lens conveying structure arranged crosswise with the film component and used for conveying lenses below the film component, a lens lifting platform located below the film component in the middle of the lens conveying structure, a lens fixing component at the upper end of the lens lifting platform, a lens gripping component on one side of the lens lifting platform, and a film cutting component vertically and movably arranged above the film component, corresponding to the upper and lower ends of the lens lifting platform.

[0005] In the aforementioned automatic lens coating machine, the lens conveying structure has an upper film conveying section and an lower film conveying section coaxially arranged, and a lens lifting platform is movably positioned between the corresponding ends of the upper film conveying section and the lower film conveying section. By breaking down the lens conveying structure into an upper film conveying section and an lower film conveying section, and emphasizing their coaxial arrangement, the input, processing, and output paths of the lenses are clearly defined. The lenses enter from the upper film conveying section, and after coating is completed on the lifting platform, they are sent out through the lower film conveying section. Simultaneously, the lens lifting platform is movably positioned between the corresponding ends of the two sections, precisely positioning the processing station and making the conveying process more seamless.

[0006] In the aforementioned automatic lens coating machine, both the film loading and unloading conveyors are conveyor belts.

[0007] In the aforementioned automatic lens coating machine, the lens fixing assembly includes several positioning parts arranged circumferentially outward on the upper part of the lens lifting platform. These positioning parts are inclined outwards from the lens lifting platform. Each positioning part has a horizontally positioned placement platform that fits against the lower surface of the lens. The end of each placement platform furthest from the center of the lens lifting platform has an inclined guide portion. The inclined guide portion facilitates the automatic sliding of the lens into the placement platform during placement. The horizontally positioned placement platform ensures stable support of the lens, while the inclined positioning parts restrict lens movement from the side, ensuring the stability of the lens placement and providing a foundation for precise subsequent coating application.

[0008] In the aforementioned automatic lens coating machine, the number of positioning parts is four, evenly distributed circumferentially around the center of the lens lifting platform. The inclined guides on the four positioning parts form a positioning step that contacts the outer circumferential surface of the lens between the end of the guide near the center of the lens lifting platform and the placement platform. The height of the inclined guide is less than the thickness of the lens. The four positioning parts, evenly distributed circumferentially, ensure the symmetry of the force applied to the lens, avoiding positioning offset caused by unilateral force. The contact between the positioning step and the outer circumferential surface of the lens further enhances the positioning effect. The height of the inclined guide is less than the thickness of the lens, ensuring that the guide only acts on the lower edge of the lens and does not obstruct the upper surface.

[0009] In the aforementioned automatic lens coating machine, the lens gripping assembly includes a rotary lifting cylinder disposed on one side of the lens lifting platform. A gripper connecting rod is connected to the rotary lifting cylinder, and a pneumatic lens gripper is located above the lens lifting platform at the end of the gripper connecting rod furthest from the rotary lifting cylinder. The combination of rotation and lifting actions enables the machine to grip lenses from the upper film conveyor, place them on the lens lifting platform, remove them from the lifting platform, and place them on the output film conveyor. The selection of the pneumatic lens gripper is tailored to the thin and fragile nature of lenses. The pneumatic drive allows for control of the gripping force through air pressure adjustment, preventing mechanical hard contact that could scratch or damage the lenses.

[0010] In the aforementioned automatic lens laminating machine, a lifting assembly is connected to the lower end of the lens lifting platform. The lens lifting platform is cylindrical and moves vertically up and down via the lifting assembly. This causes the lens to rise to adhere to the film and descend to detach from the film.

[0011] In the aforementioned automatic lens film applicator, the film conveying structure includes an unwinding roller on which a film component is mounted, and one end of the film component is wound around a circumferentially rotatable take-up roller.

[0012] In the aforementioned automatic lens coating machine, the diameter of the lens is smaller than the width of the film, and the width of the film is 10cm-12cm. This ensures that the film completely covers the upper surface of the lens.

[0013] In the aforementioned automatic lens coating machine, the film cutting assembly includes a vertically movable film cutting seat. The lower end of the film cutting seat is equipped with a circular cutter. The circular cutter has an annular cutting section, the inner diameter of which is equal to the lens diameter, and the diameter of the cutting section is 6.6cm-8cm. This ensures that the cut film part is perfectly matched to the lens size, avoiding both excessive waste due to being too large and incomplete coating due to being too small. The vertical movement of the film cutting seat coordinates with the vertical movement of the lens lifting platform. After the lens rises to adhere to the film part, the film cutting seat descends to complete the cutting. The synchronized actions of both ensure accurate cutting timing and demonstrate the synergy of the various components.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. This device automatically transfers the lens, guides the lens into position using an inclined guide, lifts the film on a lifting platform, and uses a rotating lifting cylinder to drive the gripper to pick up the lens. The entire process requires no manual operation, which greatly reduces labor costs. At the same time, it avoids lens contamination or positional deviation that may be caused by manual operation, thus improving operational stability.

[0016] 2. The device utilizes a lens fixing assembly, with four circumferentially evenly distributed positioning parts forming a symmetrical constraint. The positioning steps are in close contact with the outer circumferential side of the lens, ensuring that the center of the lens is precisely aligned with the center of the cutting part of the cutting assembly.

[0017] 3. The tilting guide of the device facilitates automatic lens placement and avoids interference with the adhesion between the film and the upper surface of the lens because its height is lower than the lens thickness. At the same time, the inner diameter of the annular cutting part of the film cutting assembly is consistent with the lens diameter, ensuring that the size of the cut film perfectly matches the lens. The precision control of the entire process from positioning to cutting effectively reduces film offset and size mismatch. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-4 As shown, an automatic lens film applicator includes a film conveying structure 2 on which a film component 1 is installed. Below the film component 1, there is a lens conveying structure 3 arranged crosswise with the film component 1 and used for conveying lenses 31. In the middle of the lens conveying structure 3, there is a lens lifting platform 4 located below the film component 1. The upper end of the lens lifting platform 4 is provided with a lens fixing component 5. A lens gripping component 6 is provided on one side of the lens lifting platform 4. A film cutting component 7 is vertically movable above the film component 1 and is arranged vertically and vertically corresponding to the lens lifting platform 4.

[0025] Combination Figure 1 and Figure 2 As shown, the lens conveying structure 3 has an upper film conveying section 32 and an lower film conveying section 33 arranged coaxially. The lens lifting platform 4 is movably disposed between the corresponding ends of the upper film conveying section 32 and the lower film conveying section 33. By dissecting the lens conveying structure 3 into the upper film conveying section 32 and the lower film conveying section 33, and emphasizing their coaxial arrangement, the input, processing, and output paths of the lens 31 are clearly defined. The lens 31 enters from the upper film conveying section 32, and after the film is applied on the lifting platform, it is sent out through the lower film conveying section 33. At the same time, the lens lifting platform 4 is movably disposed between the corresponding ends of the two sections, accurately positioning the processing station and making the conveying process more continuous.

[0026] Both the film loading conveyor 32 and the film unloading conveyor 33 are conveyor belts.

[0027] like Figure 3As shown, the lens fixing assembly 5 includes several positioning parts 51 arranged circumferentially outward on the upper end of the lens lifting platform 4. The positioning parts 51 are inclined outwards from the lens lifting platform 4. Each positioning part 51 has a horizontally positioned placement platform 52 that fits against the lower surface of the lens 31. Each placement platform 52 has an inclined guide part 53 at its end furthest from the center of the lens lifting platform 4. The inclined guide part 53 facilitates the automatic sliding of the lens 31 into the placement platform 52 during placement. The horizontally positioned placement platform 52 ensures stable support of the lens 31, while the inclined positioning parts 51 restrict the movement of the lens 31 from the side, ensuring the stability of the lens 31 and providing a foundation for precise subsequent film application.

[0028] The positioning parts 51 are four in number and evenly distributed circumferentially around the center of the lens lifting platform 4. The inclined guide parts 53 on each of the four positioning parts 51 form a positioning step 54 that contacts the outer periphery of the lens 31 between the end of the guide part 53 near the center of the lens lifting platform 4 and the placement platform 52. The height of the inclined guide part 53 is less than the thickness of the lens 31. The four positioning parts 51, evenly distributed circumferentially, ensure the symmetry of the force on the lens 31, avoiding positioning offset caused by unilateral force. The positioning step 54 contacts the outer periphery of the lens 31, further enhancing the positioning effect. The height of the inclined guide part 53 is less than the thickness of the lens 31, ensuring that the guide part only acts on the lower edge of the lens 31 and does not obstruct the upper surface of the lens 31.

[0029] like Figure 2 As shown, the lens gripping assembly 6 includes a rotary lifting cylinder 61 disposed on one side of the lens lifting platform 4. A gripper connecting rod 62 is connected to the rotary lifting cylinder 61, and a lens pneumatic gripper 63 located above the lens lifting platform 4 is provided at the end of the gripper connecting rod 62 away from the rotary lifting cylinder 61. The combination of rotation and lifting actions enables it to grip the lens 31 from the film conveying section 32, place the lens 31 on the lens lifting platform 4, and then remove the lens 31 from the lens lifting platform 4 and place it on the film output conveying section 33. The lens pneumatic gripper 63 is selected to fit the thin and fragile characteristics of the lens 31. The pneumatic drive can control the gripping force by adjusting the air pressure, avoiding mechanical hard contact that could scratch or damage the lens 31.

[0030] like Figure 1 As shown, a lifting assembly is connected to the lower end of the lens lifting platform 4. The lens lifting platform 4 is cylindrical and moves vertically up and down via the lifting assembly. This causes the lens 31 to rise to adhere to the film component 1 and to fall to detach from the film component 1.

[0031] The film conveying structure 2 includes an unwinding roller 21 on which a film component 1 is mounted, and one end of the film component 1 is wound around a take-up roller 22 that can rotate circumferentially.

[0032] Specifically, the diameter of the lens 31 is smaller than the width of the film 1, which has a width of 10cm-12cm. This ensures that the film 1 completely covers the upper surface of the lens 31.

[0033] like Figure 4 As shown, the film cutting assembly 7 includes a vertically movable film cutting seat 71. A circular cutter 72 is located at the lower end of the film cutting seat 71. The circular cutter 72 has an annular cutting section 73, the inner diameter of which is equal to the diameter of the lens 31. The diameter of the cutting section 73 is 6.6cm-8cm. This ensures that the size of the cut film part 1 perfectly matches the lens 31, preventing excessive waste due to excessive size or incomplete film application due to insufficient size. The vertical movement of the film cutting seat 71 coordinates with the vertical movement of the lens lifting platform 4. After the lens 31 rises to adhere to the film part 1, the film cutting seat 71 descends to complete the cutting. The synchronized movements of both ensure accurate cutting timing and demonstrate the synergy of the various components.

[0034] The principle of this embodiment is as follows:

[0035] Lens 31 is placed on the upper film conveyor 32 and conveyed to the lens lifting platform 4. The upper film conveyor 32 has a sensor on the side near the lens lifting platform 4. After sensing the lens 31, the lens gripping assembly 6 grips the lens 31 and places it on the upper end of the lens lifting platform 4. The positioning part 51 fixes the lens 31 so that the center of the lens 31 is centered. The lens lifting platform 4 slowly rises, and the upper surface of the lens 31 gradually contacts the film 1 to complete the bonding. The film cutting seat 71 moves downward, and the circular cutter 72 cuts out the bonding part of the film 1. The film cutting seat 71 rises, the lens lifting platform 4 descends, and the lens gripping assembly 6 removes the lens 31 and places it on the film output conveyor 33 for delivery. At the same time, the film conveying structure 2 starts winding after receiving the signal of the lens lifting platform 4 descending. It pulls the film to the length of one station and pulls the cut film 1 towards the winding roller 22. The unused film 1 moves to the top of the lens lifting platform 4, completing one bonding process.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0037] Although this document frequently uses terms such as film component 1, film conveying structure 2, unwinding roller 21, rewinding roller 22, lens conveying structure 3, lens 31, loading conveyor 32, unloading conveyor 33, lens lifting platform 4, lens fixing assembly 5, positioning part 51, placement platform 52, tilting guide part 53, positioning step 54, lens gripping assembly 6, rotary lifting cylinder 61, gripper connecting rod 62, lens pneumatic gripper 63, film cutting assembly 7, film cutting seat 71, circular cutter 72, and cutting part 73, the possibility of using other terms is not excluded.
