Description

Technical Field

[0001] This utility model relates to the field of optical lens processing equipment technology, specifically to an optical lens thickness grinding and fixing mechanism. Background Technology

[0002] An optical lens is a transparent medium designed based on optical principles. Its main function is to change the direction of light propagation through refraction or reflection, thereby achieving purposes such as focusing, imaging, or vision correction. During the manufacturing process, optical lenses require thickness grinding, which involves a series of physical and chemical processes to achieve the required precision and surface quality.

[0003] Currently, optical lenses are mostly bonded to the grinding fixture using specialized adhesives during processing. However, if the adhesive thickness is uneven, it can easily cause the lens to tilt, resulting in shape errors after grinding.

[0004] Therefore, we propose to design an optical lens thickness grinding and fixing mechanism. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] An optical lens thickness grinding and fixing mechanism includes a base, a mounting seat on the top of the base, an adsorption seat fixedly connected to the center of the top of the mounting seat, a suction cup fixedly connected to the center of the adsorption seat, an electric push rod fixedly connected to the center of the adsorption seat and the mounting seat, a piston fixedly connected to the telescopic end of the electric push rod, and an air hole opened inside the suction cup.

[0008] A movable ring is sleeved on the outer wall of the adsorption seat. The top of the movable ring has an adhesive outlet, and the outer wall of the movable ring has an adhesive injection hole. A locking bolt is inserted through the outside of the movable ring.

[0009] As a preferred embodiment of the optical lens thickness grinding and fixing mechanism of this utility model, the adsorption seat has a vacuum cylinder inside, the piston is tightly fitted to the inner wall of the vacuum cylinder, the air hole is connected to the inside of the vacuum cylinder, and the piston is driven by an electric push rod to descend in the vacuum cylinder, so as to generate negative pressure above the vacuum cylinder, which facilitates negative pressure adsorption of the optical lens.

[0010] In a preferred embodiment of the optical lens thickness grinding and fixing mechanism described in this utility model, the height of the suction cup is one millimeter higher than the top surface of the adsorption seat, which facilitates the inclusion of adhesive to assist in the bonding and positioning of the lens.

[0011] As a preferred embodiment of the optical lens thickness grinding and fixing mechanism of this utility model, a flow channel is provided between the glue injection hole and the glue outlet. The glue injection hole and the glue outlet are connected through the flow channel. The glue injection hole facilitates the injection of adhesive, which is then discharged from the glue outlet. External heating can melt the cured adhesive in the flow channel, thereby cleaning the flow channel and facilitating subsequent glue injection.

[0012] As a preferred embodiment of the optical lens thickness grinding and fixing mechanism of this utility model, the adhesive outlet has a strip-shaped cross-section. After the adhesive is discharged from the outlet, the adhesive can be evenly applied to the periphery of the bottom surface of the lens by rotating the movable ring.

[0013] In a preferred embodiment of the optical lens thickness grinding and fixing mechanism described in this utility model, the locking bolt passes through the movable ring and is threadedly connected to the adsorption seat. After the adhesive cures, the movable ring and the adsorption seat can be locked together, which facilitates subsequent grinding of the optical lens and improves stability.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes the cooperation between the adsorption seat, the movable ring, and the locking bolt. The adsorption seat provides suction to centrally position the lens, ensuring that the lens is positioned horizontally and without tilting. Subsequently, adhesive is injected around the bottom surface of the lens, which not only assists in adhesive fixation but also forms a one-millimeter support layer at the bottom of the lens, facilitating support, balancing the forces on the bottom of the lens, and improving the positioning stability of the lens.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-3 This utility model provides an optical lens thickness grinding and fixing mechanism, including a base 1, a mounting seat 2 on the top of the base 1, an adsorption seat 3 fixedly connected to the center of the top of the mounting seat 2, and a suction cup 4 fixedly connected to the center of the adsorption seat 3.

[0025] In this embodiment, the height of the suction cup 4 is one millimeter higher than the top surface of the adsorption seat 3, which facilitates the inclusion of adhesive to assist in the bonding and positioning of the lens.

[0026] An electric push rod 5 is fixedly connected to the center of the adsorption base 3 and the mounting base 2. A piston 6 is fixedly connected to the telescopic end of the electric push rod 5. An air hole 7 is opened inside the suction cup 4.

[0027] The adsorption seat 3 has a vacuum cylinder 301 inside. The piston 6 is tightly fitted to the inner wall of the vacuum cylinder 301. The air hole 7 is connected to the inside of the vacuum cylinder 301. The piston 6 is driven to descend in the vacuum cylinder 301 by the electric push rod 5, so that a negative pressure is generated above the vacuum cylinder 301, which facilitates the negative pressure adsorption of the optical lens.

[0028] A movable ring 8 is sleeved on the outer wall of the adsorption seat 3. The top of the movable ring 8 has an adhesive outlet 9. The adhesive outlet 9 has a strip-shaped cross section. After the adhesive is discharged from the adhesive outlet 9, the movable ring 8 can be rotated to make it easy to evenly apply the adhesive to the periphery of the bottom surface of the lens.

[0029] The outer wall of the movable ring 8 is provided with an injection hole 10. A flow channel is provided between the injection hole 10 and the outlet 9. The injection hole 10 and the outlet 9 are connected through the flow channel. The adhesive is injected through the injection hole 10 and discharged through the outlet 9. External heating can melt the cured adhesive in the flow channel, thereby cleaning the flow channel and facilitating subsequent injection.

[0030] A locking bolt 11 is provided through the outside of the movable ring 8. The locking bolt 11 passes through the movable ring 8 and is threadedly connected to the adsorption seat 3. After the adhesive cures, the movable ring 8 and the adsorption seat 3 can be locked together, which facilitates the subsequent grinding of the optical lens and improves stability.

[0031] When in use, first place the clean lens on top of the adsorption seat 3, start the electric push rod 5 to drive the piston 6 to descend in the vacuum cylinder 301, and generate negative pressure at the air hole 7 to adsorb the optical lens. Under the adsorption effect, the optical lens is placed horizontally on top of the adsorption seat 3.

[0032] The staff then connected the glue injection tube to the glue injection hole 10 and introduced the adhesive until it overflowed from the glue outlet 9 and gradually flowed on the top of the movable ring 8. After that, the movable ring 8 was rotated back and forth to make the adhesive evenly spread on the periphery of the bottom surface of the optical lens. Then, the adsorption seat 3 and the movable ring 8 were locked and fixed by the locking bolt 11.

[0033] At this point, the optical lens is fixed. Its fixing structure is provided by the central suction seat 3, which not only pre-positions the lens but also ensures that the lens is level. Then, adhesive is injected around the lens and evenly applied to the bottom periphery of the lens to form a one-millimeter adhesive layer that supports and positions the lens. This ensures a tight connection between the periphery of the optical lens and the movable ring 8, uniform force distribution, and improved positioning stability of the lens.

[0034] After processing is completed, the adhesive layer at the bottom of the lens is heated, and then piston 6 is raised to remove the lens. During the heating process, the adhesive in the flow channel can melt simultaneously, making it easier to inject adhesive into the next lens.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
