Description

Technical Field

[0001] This utility model relates to the technical field of smart glasses manufacturing equipment, specifically to a positioning fixture for assisting in the dispensing and assembly of eyeglass frames and lenses. Background Technology

[0002] Smart glasses have become a rapidly growing consumer electronics product globally, serving as a smart wearable communication device for young people seeking individuality. With their numerous functions finding effective applications in various fields, global demand for smart glasses is increasing month by month, and they are hailed as the next generation of mobile communication devices that can replace smartphones. In response, many manufacturers of smart glasses have deployed automated mass production equipment to cope with the market boom and the need for rapid delivery of smart glasses.

[0003] In order to accurately glue and assemble the various components of smart glasses, the efficient flow of semi-finished smart glasses needs to be precisely controlled in each process before the product is formed. Among them, the installation process of the eyeglass frame and lens requires the application of a precise positioning clamping fixture. Therefore, a convenient positioning clamping fixture needs to be specially designed. Utility Model Content

[0004] The purpose of this invention is to facilitate the adhesive application and installation of smart glasses and lenses. A convenient quick-release and quick-install positioning and clamping fixture needs to be specially designed to efficiently complete the installation of lenses and smart glasses frames, improve installation accuracy and convenience, and increase mass production efficiency.

[0005] The technical solution adopted to solve the above problems is:

[0006] A positioning fixture for assisting in the dispensing and assembly of eyeglass frames and lenses is proposed, including...

[0007] The base is used to support the jig body.

[0008] A contour stage is used to position the eyeglass frame to be assembled.

[0009] Elastic clamping components used to press and lock the hinges on both sides of the eyeglass frame.

[0010] And a movable clamping component that presses and locks the eyeglass frame in place.

[0011] The contouring stage is mounted on the base via a connector. Its upper surface is equipped with positioning blocks that define the eyeglass frame to be fitted with lenses. These include an upper frame positioning block, a bridge positioning block, and a hinge positioning block. Each positioning block is arranged corresponding to the upper frame, bridge, and hinge positions of the eyeglass frame, respectively. Furthermore, the surfaces of each positioning block that contact the eyeglass frame are provided with contoured curved surfaces to ensure full contact between the positioning blocks and all parts of the eyeglass frame, resulting in precise positioning.

[0012] The elastic clamping assembly is distributed on both sides of the contour stage and includes a hinge base, a hinge shaft, a tension spring, and an elastic pressure block. The elastic pressure block is movably connected to the hinge base through a through-hole in the hinge shaft. The tension spring is mounted between the hinge shaft and the elastic pressure block, driving the elastic pressure block to press down on the eyeglass frame hinge, thus fully positioning the eyeglass frame in the left-right direction.

[0013] The movable clamping assembly is positioned in the front end of the positioning block in the back-to-back direction and is arranged directly opposite the lower left and right frames of the eyeglasses frame. It includes a lower left frame positioning block, a lower right frame positioning block, a pull rod, a connecting rod connected to the pull rod, a slider rail assembly, and a guide pin, a push spring, and a limiting plate that drive the lower left or lower right frame positioning block to slide linearly in the back-to-back direction.

[0014] Furthermore, the lower left and lower right frame positioning blocks are used to position the lower and right frames of the eyeglasses frame, respectively. The lower left and lower right frame positioning blocks have contoured curved surfaces on their contact surfaces with the eyeglasses frame to ensure full contact between the positioning blocks and the eyeglasses frame and accurate positioning.

[0015] Furthermore, the lower left and lower right frame positioning blocks are connected to the left and right ends of the connecting rod, respectively. The middle part of the connecting rod is connected to the pull rod. The lower ends of the lower left and lower right frame positioning blocks are provided with slider rail assemblies. Under the push and pull of the pull rod, the lower left and lower right frame positioning blocks are driven to slide linearly back and forth.

[0016] Furthermore, the lower left and lower right frame positioning blocks each have at least two guide holes on their front faces. The guide holes are clearance-fitted with the guide pin shaft holes. The guide pin is connected to the limiting plate, and the limiting plate is fixedly connected to the front face of the contour stage, thereby restricting the sliding freedom of the guide pin, the lower left frame positioning block, and the lower right frame positioning block in the front-back linear direction.

[0017] Furthermore, the slider of the slider-rail assembly is connected to the lower left and lower right frame positioning blocks, while the rail is connected to the base, ensuring that the lower left and lower right frame positioning blocks are stably and reliably supported by the slider-rail assembly.

[0018] Furthermore, a push spring is sleeved between the guide pin and the guide hole. After the limiting plate is connected to the contouring stage, the lower left and lower right frame positioning blocks are pulled forward by the pull rod and slide, compressing the push spring. When the eyeglass frame is placed and the positioning is completed, the pull force of the pull rod is released. Under the action of the push spring, the lower left and lower right frame positioning blocks are reset and clamp the lower left and right frames of the eyeglass frame.

[0019] The beneficial effects of this utility model are:

[0020] 1. The positioning fixture used to assist in the dispensing and assembly of eyeglass frames and lenses uses a profiling table to position the outer contour of the eyeglass frame to be assembled with lenses. The positioning blocks in each part can be positioned in a targeted manner, resulting in high positioning accuracy.

[0021] 2. The elastic clamping component and the movable clamping component can effectively control the adjustment of the spacing between the positioning blocks on the profilograph stage, providing convenience for the picking and placing of eyeglass frames;

[0022] 3. The contoured surface designed with multiple positioning blocks fully conforms to the upper frame, lower frame, bridge, and hinges of the eyeglasses frame, ensuring accurate positioning before clamping while quickly picking up and putting away the eyeglasses frame. This allows for efficient installation of the lenses and smart glasses frames, improving installation accuracy and convenience, and increasing mass production efficiency. Attached Figure Description

[0034] Please see Figure 1 This embodiment proposes a positioning fixture for assisting in the dispensing and assembly of eyeglass frames and lenses, including a base 1 for supporting the fixture body, a contouring platform 2 for positioning the eyeglass frame 7 to be assembled, an elastic clamping assembly for pressing and locking the hinges on both sides of the eyeglass frame, and a movable clamping assembly 5 for pressing and locking the eyeglass frame 7.

[0035] See Figure 1 and Figure 2The contouring stage 2 is fastened to the base 1 with screws. The upper surface is provided with positioning blocks that define the eyeglass frame 7 to be fitted with lenses, including the upper left eyeglass frame positioning block 201, the bridge nose positioning block 202, the upper right eyeglass frame positioning block 203, and the hinge positioning block. Each positioning block is arranged corresponding to the upper left eyeglass frame, upper right eyeglass frame, bridge nose, and hinge positions of the eyeglass frame 7, and each positioning block has a contouring curved surface on the surface that fits against the eyeglass frame 7, including the upper left eyeglass frame contouring curved surface 2011, the bridge nose contouring curved surface 2021, and the upper right eyeglass frame contouring curved surface 2031, to ensure that the positioning blocks are in full contact with each part of the eyeglass frame 7 and that the positioning is accurate.

[0036] See Figure 1 The elastic clamping components are distributed on both sides of the contour stage 2, including a hinge seat 303, a hinge shaft, a tension spring 302, and an elastic pressure block. The elastic pressure block and the hinge seat 303 are movably connected through the hinge shaft hole. The tension spring 302 is mounted between the hinge shaft and the elastic pressure block, which drives the elastic pressure block to press down on the hinge of the eyeglass frame 7, thus fully positioning the eyeglass frame 7 in the left and right directions.

[0037] As a further technical solution of this embodiment, the movable clamping assembly 5 is arranged in the front end of the positioning block in the back-to-back direction and is positioned directly opposite the lower left and lower right frames of the eyeglass frame 7. It includes a lower left frame positioning block 501, a lower right frame positioning block 502, a pull rod 503, a connecting rod 506 connected to the pull rod 503, a slider rail assembly 508, and a guide pin 504, a push spring 507, and a limiting plate 6 that drive the lower left frame positioning block 501 or the lower right frame positioning block 502 to slide linearly in the back-to-back direction.

[0038] More specifically, see Figure 6 The lower left frame positioning block 501 and the lower right frame positioning block 502 are used to position the lower frame and the right frame of the eyeglass frame 7, respectively. The lower left frame positioning block 501 and the lower right frame positioning block 502 are respectively provided with a lower left frame contoured curved surface 5011 and a lower right frame contoured curved surface 5021 on their positioning contact surfaces with the eyeglass frame 7, to ensure that the positioning blocks are in full contact with the eyeglass frame 7 and the positioning is accurate.

[0039] Further implementation plans are as follows, see [link / reference] Figure 4 and Figure 5 The lower left frame positioning block 501 and the lower right frame positioning block 502 are respectively connected to the left and right ends of the connecting rod 506. The middle part of the connecting rod 506 is connected to the pull rod 503. The lower ends of the lower left frame positioning block 501 and the lower right frame positioning block 502 are provided with slider rail assemblies 508. Under the push and pull of the pull rod 503, the lower left frame positioning block 501 and the lower right frame positioning block 502 are driven to slide linearly back and forth.

[0040] Further implementation plans are as follows, see [link / reference] Figure 4The lower left frame positioning block 501 and the lower right frame positioning block 502 each have two guide holes on their front end faces. The guide holes are clearance-fitted with the shaft holes of the guide pin 504. The guide pin 504 is connected to the limiting plate 6, and the limiting plate 6 is fixedly connected to the front end face of the contour stage 2, thereby restricting the sliding freedom of the guide pin 504, the lower left frame positioning block 501, and the lower right frame positioning block 502 in the front-back linear direction.

[0041] Further implementation plans are as follows, see [link / reference] Figure 5 The slider of the slider-rail assembly 508 is connected to the lower left frame positioning block 501 and the lower right frame positioning block 502, while the rail is connected to the base 1, ensuring that the lower left frame positioning block 501 and the lower right frame positioning block 502 are stably and reliably supported by the slider-rail assembly 508.

[0042] As a further technical solution of this embodiment, see [link to relevant documentation]. Figure 4 and Figure 5 A push spring 507 is sleeved between the guide pin 504 and the guide hole. After the limiting plate 6 is connected to the contour table 2, the lower left frame positioning block 501 and the lower right frame positioning block 502 are pulled forward by the pull rod 503, compressing the push spring 507. When the eyeglass frame 7 is placed and the positioning is completed, the pulling force of the pull rod 503 is released. Under the action of the push spring 507, the lower left frame positioning block 501 and the lower right frame positioning block 502 are reset and clamp the lower left and right frames of the eyeglass frame 7.
