Description

Technical Field

[0001] This utility model relates to the field of lens manufacturing technology, specifically to a gripping device for manufacturing cemented lenses. Background Technology

[0002] The manufacturing technology of cemented lenses (also known as composite lenses) stems from the demand for aberration correction and performance improvement in optical systems. Its development involves advancements in optical theory, materials science, and precision manufacturing. With the development of science and technology, people have increasingly higher requirements for lens image quality. To meet these high requirements, lens design must strive to eliminate various aberrations that affect image quality. Chromatic aberration is the most important factor affecting image quality. To eliminate chromatic aberration or minimize it, the lenses must be cemented together. Traditional cementing processes have significant shortcomings: low cementing efficiency and low production yield.

[0003] A search revealed a utility model patent with publication number CN213457493U, which discloses an optical lens bonding device. This device primarily relates to the field of optical lens processing equipment technology. It includes a slide rail, a servo motor, and a support. A slider is slidably connected to the slide rail. The output end of the servo motor is connected to a lead screw via a coupling. The lead screw passes through the slider and is threadedly connected to it. A glue container and a cylinder are respectively mounted on the support. A placement groove is provided on the upper surface of the slider, and a bonding platform is placed within the placement groove. A bonding lens is placed within the bonding platform, and a glue inlet hose connecting to the bonding lens is provided on the bonding platform. The desired bonding lens is placed in the bonding platform, and then the bonding platform is placed in the placement groove on the upper surface of the slider. The servo motor is activated, causing the lead screw to rotate, which in turn moves the slider on the slide rail, dripping glue and pressing it together to complete the bonding of the lens. This method ensures high bonding precision, increases the bonding yield, and enables large-scale stable bonding of lens assemblies.

[0004] The aforementioned patent merely places the required cemented lens into a cementing platform, then places the cementing platform into a placement groove on the upper surface of the slider, starts the servo motor to make the lead screw rotate, and then moves the slider on the slide rail to drip glue and press it together to complete the installation of the cemented lens. This ensures high bonding accuracy, improves the bonding yield, and enables large-scale stable cemented lens assembly. However, it cannot fully and flexibly grip the lenses waiting to be bonded. Currently, it requires manual movement of the lenses to the cementing platform before proceeding to the next process. The operation is not meticulous enough, and there is a risk of the lenses falling. In addition, the gripping structure lacks a self-cleaning function. If there are dust or impurities on the lens surface, it will affect the viscosity of subsequent bonding and hinder lens manufacturing.

[0005] Therefore, it is necessary to invent a gripping device for manufacturing cemented lenses to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a gripping device for manufacturing bonded lenses. Before the elastic silicone comes into contact with the object, a controller connected to the device can heat the internal Field alloy to a liquid or soft state, allowing the elastic silicone to deform and wrap around the lens surface. During the wrapping stage, the liquid alloy flows under pressure, adaptively filling the object's contour to achieve seamless clamping. After cooling by a micro fan, the alloy stops heating and quickly solidifies, forming a rigid structure that, together with the concave and convex strips, locks the object, increasing the friction and gripping stability after solidification. This solves the problem in existing technologies where lenses awaiting bonding cannot be gripped flexibly enough. Currently, it is necessary to manually move the lens onto the bonding platform before proceeding to the next process, which is not careful enough and may lead to the risk of the lens falling off.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gripping device for manufacturing cemented lenses, comprising a mounting shell, an electric push rod mounted on the side of the mounting shell, a push block provided on the rear side of the inner wall of the mounting shell, the output end of the electric push rod being fixedly connected to the push block, and a movable rod rotatably connected to the bottom wall of the mounting shell, the number of the movable rods being set to two, the two movable rods being symmetrically distributed about the central axis of the mounting shell, the relatively far side of the two movable rods being connected to the inner wall of the mounting shell by a spring, and a guide slider being hinged to the relatively close side of the two movable rods, and guide grooves being provided on both sides of the push block, the guide sliders matching the guide grooves.

[0008] Preferably, an elastic silicone is fixedly connected to the inner side of one end of the movable rod, the elastic silicone is encapsulated with Field alloy, a PTC heating element is embedded in the inner wall of the elastic silicone, the PTC heating element is in physical contact with the Field alloy, the outer wall of the elastic silicone is evenly distributed with concave and convex strips, and a miniature fan is installed inside the side of the movable rod, the miniature fan being located on the side of the elastic silicone.

[0009] Preferably, a positioning block is provided on the rear side of the inner wall of the mounting shell, and the number of positioning blocks is set to two. The two positioning blocks are symmetrically distributed about the central axis of the push block. A slot is opened on the front side of the positioning block, and the slot is equidistant about the front side of the positioning block.

[0010] Preferably, a limiting cavity two is formed at the other end of the movable rod, and a limiting block two is movably connected to the limiting cavity two through a spring one. A locking rod is fixedly connected to the side of the limiting block two away from the spring one, and the locking rod matches the locking groove.

[0011] Preferably, a jet nozzle is fixedly provided on the side of the movable rod, a miniature air compressor is installed at the bottom of the mounting housing, and a hose connects the jet nozzle and the miniature air compressor.

[0012] Preferably, a horizontal plate is fixedly connected to the middle of the front side of the mounting shell, and an infrared sensor is installed on the front side of the horizontal plate.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. The electric push rod pushes the push block back and forth, and the guide slider slides along the guide groove. This assists the two movable rods to rotate around the connection point with the bottom wall of the mounting shell. This allows the two elastic silicone to clamp lenses of different sizes. Before the elastic silicone comes into contact with the object, the controller connected to the equipment can heat the Feld alloy inside to a liquid or soft state, so that the elastic silicone can deform and wrap around the lens surface. During the wrapping stage, the liquid alloy flows under pressure, adaptively filling the object's contour to achieve seamless clamping. After cooling by a micro fan, the alloy stops heating and quickly solidifies, forming a rigid structure that locks the object with the concave and convex strips, increasing the friction and gripping stability after solidification.

[0015] 2. When the lens is gripped by the two movable rods, the infrared sensor detects the object approaching. The Arduino connected to the manufacturing equipment reads a high-level signal, which triggers the relay. The relay connects the power supply of the miniature air compressor (or opens the solenoid valve). Air is then used to clean the lens surface by air jetting through the air nozzle, avoiding direct bonding that would affect the viscosity. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-6 The illustrated gripping device for manufacturing cemented lenses includes a mounting housing 1. An electric push rod 2 is mounted on the side of the mounting housing 1. A push block 3 is located on the rear side of the inner wall of the mounting housing 1. The output end of the electric push rod 2 is fixedly connected to the push block 3. Two movable rods 6 are rotatably connected to the bottom wall inside the mounting housing 1. The two movable rods 6 are symmetrically distributed about the central axis of the mounting housing 1. The relatively far sides of the two movable rods 6 are connected to the inner wall of the mounting housing 1 by a spring 23. The relatively close sides of the two movable rods 6 are hinged to... Guide slider 10 and push block 3 are provided with guide grooves 11 on both sides. Guide slider 10 matches guide groove 11. Mounting shell 1 can be directly installed in the area of ​​manufacturing equipment near the lens for gluing. After being driven by electric push rod 2, push block 3 is pushed and pulled back and forth. During the movement of push block 3, guide slider 10 slides along guide groove 11. During the sliding process, it will drive movable rod 6 to rotate, so that two elastic silicone 16 can clamp the lens. The setting of spring 23 can help movable rod 6 to reset when electric push rod 2 and push block 3 return to their original positions.

[0027] An elastic silicone rubber 16 is fixedly connected to the inner side of one end of the movable rod 6. The elastic silicone rubber 16 is encapsulated with Field alloy 7. A PTC heating element 8 is embedded in the inner wall of the elastic silicone rubber 16. The PTC heating element 8 is in physical contact with the Field alloy 7. The outer wall of the elastic silicone rubber 16 is evenly distributed with concave and convex strips 9. A miniature fan 22 is installed inside the side of the movable rod 6. The miniature fan 22 is located on the side of the elastic silicone rubber 16. The PTC heating element 8 is attached to the inner side of the cavity of the elastic silicone rubber 16 and is in close contact with the Field alloy 7. This results in minimal thermal resistance and the fastest response. The concave and convex strips 9 can enhance the friction and gripping stability after curing.

[0028] A positioning block 4 is provided on the rear side of the inner wall of the mounting shell 1. The number of positioning blocks 4 is set to two. The two positioning blocks 4 are symmetrically distributed about the central axis of the push block 3. A slot 5 is provided on the front side of the positioning block 4. The slots 5 are equidistantly distributed about the front side of the positioning block 4.

[0029] The other end of the movable rod 6 has a limiting cavity 12. A limiting block 14 is movably connected to the limiting cavity 12 via a spring 13. A locking rod 15 is fixedly connected to the side of the limiting block 14 away from the spring 13. The locking rod 15 matches the locking groove 5. When the movable rod 6 rotates, the locking rod 15 can move in front of the positioning block 4 and automatically engage with the locking groove 5 by the expansion of the spring 13 for locking.

[0030] A jet nozzle 17 is fixedly installed on the side of the movable rod 6, and a miniature air compressor 18 is installed at the bottom of the mounting housing 1. A hose 19 connects the jet nozzle 17 and the miniature air compressor 18. The jet nozzle 17 is connected to the miniature air compressor 18 through the hose 19. It is existing technology to install a solenoid valve at the connection between the hose 19 and the miniature air compressor 18 to control the start and stop of the jet operation. When the object is close, the relay will turn on the power of the miniature air compressor 18 or the solenoid valve will open, so that the jet nozzle 17 can start the jet operation to clean the surface of the lens.

[0031] A horizontal plate 20 is fixedly connected to the middle of the front side of the mounting housing 1, and an infrared sensor 21 is installed on the front side of the horizontal plate 20.

[0032] The working principle of this practical application is as follows:

[0033] Install the mounting shell 1 at the designated moving device position on the equipment. The horizontal or vertical installation can be determined according to the lens placement. The electric push rod 2 is activated and pushes the push block 3 to move. During the movement, the two movable rods 6 move away from each other and closer together. When they are close together, the elastic silicone 16 is used to grip the lens. The preset controller connected to the equipment can heat the Feld alloy 7 inside to a liquid or soft state, so that the elastic silicone 16 can deform and wrap around the lens surface, adaptively filling the object contour to achieve seamless clamping. After cooling by the controller's micro fan 22, the Feld alloy 7 stops heating and quickly solidifies, forming a rigid structure that locks the object with the concave and convex strips 9, increasing the friction and gripping stability after solidification. After successful gripping, the infrared sensor 21 detects the object approaching and controls the jet nozzle 17 to spray air onto the lens surface for cleaning. After cleaning, the lens can be placed on the gluing processing table with the moving device.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
