Description

Technical Field

[0001] This utility model relates to the field of eyeglass manufacturing technology, specifically to a high-efficiency assembly fixture for eyeglass manufacturing. Background Technology

[0002] High-efficiency assembly fixtures for eyeglass manufacturing are mainly used to accurately position and fix components such as frames and temples during the eyeglass manufacturing process, thereby improving assembly efficiency and precision. Through specific structures (such as slots and clamping components), they can adapt to eyeglass components of different specifications and quickly complete processes such as lens insertion and temple connection, reducing manual adjustment time. However, in the temple assembly stage of eyeglasses production, the precise fixing of the temples to components such as the frame is crucial to product quality. The temples have a unique structure, with diverse shapes at the wearing end that contacts the ear. Different styles of eyeglasses have significantly different shapes at the wearing end. Existing assembly fixtures mostly use a uniform fixed mold to fix the temples. Due to the different shapes of the wearing end, there are easily mismatches between the fixed mold and the temple, affecting assembly accuracy. To solve the accuracy problem, changing the mold for different temple shapes can improve adaptability to some extent, but the mold changing process is time-consuming and labor-intensive. Especially in the scenario of producing multiple eyeglass models together, frequent mold changes will significantly reduce production efficiency and increase production costs, making it difficult to meet the needs of efficient and flexible production. Therefore, to address the above problems, a high-efficiency assembly fixture for eyeglasses production is proposed. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-7 This utility model provides a technical solution: A high-efficiency assembly fixture for eyeglass manufacturing includes a fixture base 1. A grooved support 2 for the wearing end and a grooved support 3 for the temple rod are fixedly connected to the bottom of one side of the fixture base 1. A pneumatic pressure mechanism 4 is fixedly installed on the top of the other side of the fixture base 1. An adaptive assembly component 5 is fixed to the front end of the pneumatic pressure mechanism 4. The adaptive assembly component 5 includes a housing 51. An elastic airbag 52 is fixedly installed on one side inside the housing 51. A compression triggering mechanism 6 is installed on the surface of the elastic airbag 52. A pneumatic telescopic rod 53 is fixedly installed on the other side inside the housing 51. A compensating wedge 54 is fixedly connected to the telescopic end of the pneumatic telescopic rod 53. Guide wheels 55 rotate at the four corners of the top of the compensating wedge 54. An installation cavity 56 is provided on the outer side of the inclined block 54. A vibration trigger strip 57 is fixedly connected to the inner side of the installation cavity 56. A guide groove assembly 58 is provided on the inner wall of the housing 51. The guide groove assembly 58 includes an inclined guide groove 581 and an installation groove 582. The included angle between the inclined guide groove 581 and the installation groove 582 is 30°. The installation groove 582 is parallel to the housing 51. The height of the installation cavity 56 is adapted to the height of the installation groove 582. The inclined guide groove 581 is opened in the middle of the inner wall of the housing 51, and the installation groove 582 is opened at the bottom of the inner wall of the housing 51. A linearly arranged protrusion 583 is fixedly connected to the inner side of the installation groove 582. The guide wheel 55 rotates with the inclined guide groove 581. As a further implementation of this solution, there are two adaptive assembly components 5. The positions of the two adaptive assembly components 5 correspond to the positions of the grooved support 2 at the wearing end and the grooved support 3 at the temple rod, respectively, to ensure that the assembly force and precision on both sides are consistent and to avoid the overall structural imbalance of the glasses caused by the assembly error on one side. As a further implementation of this solution, the compression triggering mechanism 6 includes a compression seat 61, which is slidably disposed on the inner wall of the housing 51. A receiving cavity 62 is provided on the inner side of the compression seat 61, and a compression block 63 symmetrically arranged on the inner side of the receiving cavity 62 is fixed thereon. The top of the compression block 63 has an arc-shaped structure to prevent the elastic airbag 52 from being punctured by sharp parts, extend the service life of the component, and ensure the long-term stable operation of the clamp. The compression block 63 fits into the elastic airbag 52. As a further implementation of this solution, the elastic airbag 52 and the pneumatic telescopic rod 53 are parallel to each other. One end of the elastic airbag 52 and the air inlet end of the pneumatic telescopic rod 53 are connected by a gas passage pipe 59. The gas passage pipe 59 and the shell 51 are parallel to each other. The parallel layout reduces the bending loss in the gas transmission process, ensures that the pneumatic telescopic rod 53 can receive gas power in a timely and stable manner, and ensures the continuity and timeliness of the action of the compensating inclined block 54. As a further implementation of this solution, there is a gap between the vibration trigger strip 57 and the mounting cavity 56. The front end of the vibration trigger strip 57 and the front end of the protrusion 583 are both arc-shaped. The vibration trigger strip 57 and the protrusion 583 slide together. When the compensation block 54 moves down along the inclined guide groove 581, it can fill the gap and generate vibration through the cooperation between the protrusion 583 and the vibration trigger strip 57, thereby enhancing the fit. As a further implementation of this solution, the pneumatic pressure mechanism 4 includes a connecting rod base 41, which is fixedly connected to the clamp base 1. An electric cylinder 42 is fixedly connected to the bottom end of the connecting rod base 41. The telescopic end of the electric cylinder 42 passes through the interior of the connecting rod base 41. A swing arm 43 is hinged to the telescopic end of the electric cylinder 42. The front end of the swing arm 43 is fixedly connected to the housing 51. A hinge block 44 is hinged to the middle of the swing arm 43. A hinge seat 45 is hinged to the bottom end of the hinge block 44. The bottom end of the hinge seat 45 is hinged to one side of the connecting rod base 41. Through the hinge structure, the position of the adaptive assembly component 5 is accurate and stable when pressure is applied.

[0017] Workflow: Place the temple to be assembled on the wearing end grooved support 2 and the temple rod grooved support 3 above the clamp base 1. The wearing end of the temple corresponds to the wearing end grooved support 2, and the temple rod corresponds to the temple rod grooved support 3. At this time, the adaptive assembly component 5 is in its initial position. When the pneumatic pressure mechanism 4 is activated, the connecting rod base 41 is fixed to the clamp base 1 for support. The telescopic end of the electric cylinder 42 passes through the connecting rod base 41, and its hinged swing arm 43 is fixedly connected to the shell 51 in front and the hinge block 44 in the middle. The bottom end of the hinge block 44 is hinged to the hinge seat 45. The bottom end of the hinge seat 45 is hinged to one side of the connecting rod base 41. Through the hinge structure, the position of the adaptive assembly component 5 is accurate and stable when pressure is applied. The swing arm 43 drives the adaptive assembly component 5 to apply pressure towards the temple. During the movement of the adaptive assembly component 5, the compression triggering mechanism 6 first contacts the upper surfaces of the wearing end grooved support 2 and the temple rod grooved support 3. At this time, the compression seat 61 slides on the inner wall of the housing 51, and the compression block 63 in the inner receiving cavity 62 compresses the elastic airbag 52. The top of the compression block 63 has an arc-shaped structure, which can avoid sharp compression from damaging the elastic airbag 52 and protect the elastic airbag 52. After the elastic airbag 52 is compressed, the internal gas is injected into the pneumatic telescopic rod 53 through the air passage connecting pipe 59, providing power for the movement of the pneumatic telescopic rod 53. The air passage connecting pipe 59 realizes the gas transmission between the elastic airbag 52 and the pneumatic telescopic rod 53, and it is set parallel to the component housing 51 to ensure the stability of the gas transmission path. After receiving the gas, the telescopic end of the retracting rod 53 pushes the compensating inclined block 54 forward. The initial position of the compensating inclined block 54 is aligned with the placement slots of the wearing end grooved support 2 and the temple rod grooved support 3. During the forward movement, the guide wheel 55 extends downward along the inclined guide groove 581 in the middle of the inner wall of the housing 51. The guide wheel 55 moves along the inclined guide groove 581 to provide guidance for the movement of the compensating inclined block 54. The volume of the compensating inclined block 54, which moves downward, fills the gaps that may exist between the temple, the wearing end grooved support 2, and the temple rod grooved support 3. At the same time, the linearly arranged protrusions 583 in the mounting groove 582 come into contact with the vibration trigger strip 57. The two slide together to generate high-frequency vibration. This vibration is transmitted to the temple and the wearing end, making the fit between the wearing end grooved support 2 and the temple rod grooved support 3 tighter, further reducing the gap and ensuring assembly accuracy.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
