Description

Technical Field

[0001] This application relates to the field of eyeglass manufacturing technology, and in particular to an ultrasonic inlay structure for eyeglass hinges. Background Technology

[0002] Currently, the installation of eyeglass hinges is a crucial step in eyeglass manufacturing, directly affecting the lifespan and wearing comfort of the glasses. Traditional installation techniques mostly use mechanical pressing or gluing methods, which have problems such as low precision, poor efficiency, and easy to cause hinge misalignment or frame damage.

[0003] In existing technologies, there are two main types: one is a fixed ultrasonic mounting machine, where the mounting head is in a fixed position and can only process a single frame size. Changing products requires readjusting the equipment, resulting in low production efficiency; the other is a manually adjustable machine, where the mounting head position is adjusted manually to adapt to different products, but the adjustment accuracy depends on the operator's experience and is time-consuming. Neither of these two solutions can achieve rapid and accurate multi-size adaptation.

[0004] Regarding the aforementioned technologies, fixed equipment lacks flexibility and cannot meet the needs of small-batch, multi-variety production; manually adjustable equipment is difficult to guarantee precision, and the adjustment process is prone to human error, resulting in misalignment of hinge mounting positions, high frame damage rates, and also a serious problem of raw material waste. Summary of the Invention

[0005] To address the issues of fixed equipment's poor flexibility in meeting the needs of small-batch, multi-variety production, and the difficulty in guaranteeing the precision of manually adjustable equipment, which is prone to human error during adjustment, leading to problems such as hinge mounting position deviation and high frame damage rate, this application provides an ultrasonic mounting structure for eyeglass hinges.

[0006] This application provides an ultrasonic inlay structure for an eyeglass hinge, employing the following technical solution:

[0007] An ultrasonic inlay structure for eyeglass hinges includes a support frame for overall support, an ultrasonic inlay unit for ultrasonic inlay of the eyeglass hinges is provided on the support frame, a lateral adjustment mechanism for adjusting the lateral position of the ultrasonic inlay unit is provided on the support frame, a longitudinal adjustment mechanism for adjusting the longitudinal position of the ultrasonic inlay unit is provided on the lateral adjustment mechanism, and the ultrasonic inlay unit is mounted on the longitudinal adjustment mechanism.

[0008] By adopting the above technical solution, the horizontal adjustment mechanism and the vertical adjustment mechanism form a "two-dimensional adjustable" adjustment space. With simple adjustments, it can adapt to different sizes of frames (such as children's and adult sizes), different types of hinges (such as spring hinges and ordinary hinges), and even different material inlay requirements. At the same time, an ultrasonic inlay unit that can accurately position the hinge can precisely control the position and direction of the hinge. During the inlay process, the hinge can be accurately vertically implanted into the frame, reducing hinge offset, improving production efficiency, and reducing waste of raw materials.

[0009] Preferably, the ultrasonic embedding unit includes a frame, an ultrasonic transducer, a spring plate, and a welding head. The ultrasonic transducer is installed on the inner wall of the frame, the spring plate is disposed between the welding head and the ultrasonic transducer, and the welding head is connected to the ultrasonic transducer.

[0010] By adopting the above technical solution, the frame is responsible for overall fixation (supporting the ultrasonic transducer and welding head, and preventing overall displacement during vibration); the ultrasonic transducer is the energy source (core functional component); the welding head directly acts on the workpiece (contact execution component); and the spring plate undertakes the auxiliary function of "elastic buffering + pressure compensation" - there are no redundant parts, the structure is simple, and assembly and maintenance are convenient.

[0011] Preferably, the welding head is provided with a hinge positioning head for ultrasonic inlay positioning of the eyeglass hinge.

[0012] By adopting the above technical solution, the hinge positioning head always "holds" the hinge during the inlay process (in conjunction with the pressure applied by the welding head). Even under high-frequency vibration and pressure, the hinge will not shift, ensuring that the ultrasonic energy is fully applied to the contact surface between the hinge and the frame, thus guaranteeing the bonding strength.

[0013] Preferably, the lateral adjustment mechanism includes a first driving member, a first lead screw, a first moving block, and a first annular block. The first driving member is mounted on a support frame. The output end of the first driving member is connected to one end of the first lead screw, and the other end of the first lead screw is rotatably connected to the support frame. The first moving block is threadedly connected to the first lead screw. The first annular block is sleeved on the surface of the support frame, and the moving block is connected to the first annular block.

[0014] By adopting the above technical solution, the first lead screw drive achieves micron-level adjustment, meeting the positioning requirements of small-sized eyeglass workpieces; the combination of the first annular block and the support frame limits swaying and ensures smooth movement; the first drive component directly drives the first lead screw, which has a simple structure and supports automatic control; it can be adapted to the lateral position adjustment of different sized eyeglass frames, improving the applicability of the equipment.

[0015] Preferably, the support frame is provided with a guide groove, and the inner wall of the first annular block is provided with a guide block that cooperates with the guide groove.

[0016] By adopting the above technical solution, after the guide block is embedded in the guide groove, the two form a "mechanical engagement" rather than relying solely on the inner surface of the annular block to adhere to the support frame. During vibration, the annular block is less likely to undergo "relative displacement" with the support frame, reducing positional shifts caused by vibration transmission.

[0017] Preferably, the longitudinal adjustment mechanism includes a support member, a second driving member, a second lead screw, a second moving block, and a second annular block. The support member is mounted on the first annular block, the second driving member is mounted on the top of the support member, the output end of the second driving member is connected to one end of the second lead screw, the other end of the second lead screw is rotatably connected to the inner wall of the support member, the second moving block is threadedly connected to the second lead screw, the second lead screw is connected to the second annular block, the second annular block is slidably connected to the support member, and the second annular block is sleeved on the surface of the support member.

[0018] By adopting the above technical solution, when the second driving component (such as a servo motor) drives the second lead screw to rotate, the second moving block achieves "uniform speed and equal distance" longitudinal movement through thread engagement, avoiding the "displacement overshoot" caused by air pressure fluctuations in the traditional "cylinder push", thereby ensuring that the pressing depth of the welding head needs to be controlled when the eyeglass hinge is inlaid.

[0019] Preferably, the support member has a sliding groove for guiding the second annular block, and one side of the annular block is located in the sliding groove.

[0020] By adopting the above technical solution, the sliding groove runs longitudinally through the support (the length matches the adjustment stroke). When the embedded part of the annular block slides along the groove, the trajectory is strictly limited by the direction of the groove, ensuring that no matter what height it is adjusted to, the movement trajectory of the second annular block is always parallel to the longitudinal axis, avoiding "spiral offset".

[0021] Preferably, the ultrasonic embedding unit further includes a drive motor for driving the ultrasonic embedding unit to operate; the drive motor is mounted on the top of the ultrasonic embedding unit.

[0022] By adopting the above technical solution, the drive motor needs to provide power for the core actions of the ultrasonic embedding unit (such as the embedding and pressing of the welding head), and the top-mounted layout can shorten the power transmission distance.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The horizontal adjustment mechanism and the vertical adjustment mechanism form a "two-dimensional adjustable" adjustment space. With simple adjustments, it can adapt to different sizes of frames (such as children's and adult sizes), different types of hinges (such as spring hinges and ordinary hinges), and even different material inlay requirements. At the same time, an ultrasonic inlay unit that can accurately position the hinge can precisely control the position and direction of the hinge. During the inlay process, the hinge can be accurately inserted vertically into the frame, reducing hinge offset, improving production efficiency, and reducing the waste of raw materials.

[0025] 2. The first lead screw drive enables micron-level adjustment, meeting the positioning requirements of small-sized eyeglass workpieces; the combination of the first annular block and the support frame limits wobbling and ensures smooth movement; the first drive component directly drives the first lead screw, which has a simple structure and supports automatic control; it can be adapted to the lateral position adjustment of different sized frames, expanding the applicability of the equipment;

[0026] 3. When the second driving component (such as a servo motor) drives the second lead screw to rotate, the second moving block achieves "uniform speed and equal distance" longitudinal movement through thread engagement, avoiding "displacement overshoot" caused by air pressure fluctuations in traditional "cylinder push", thereby ensuring that the pressing depth of the welding head needs to be controlled when the eyeglass hinge is inlaid.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0034] This application discloses an ultrasonic inlay structure for eyeglass hinges.

[0035] Reference Figure 1 An ultrasonic inlay structure for eyeglass hinges includes a support frame 100 for overall support, an ultrasonic inlay unit 200 for ultrasonic inlay of the eyeglass hinge, a lateral adjustment mechanism 300 for adjusting the lateral position of the ultrasonic inlay unit 200, and a longitudinal adjustment mechanism 400 for adjusting the longitudinal position of the ultrasonic inlay unit 200. The ultrasonic inlay unit 200 is mounted on the longitudinal adjustment mechanism 400, which is mounted on the lateral adjustment mechanism 300, which is located on the support frame 100. The combination of the lateral adjustment mechanism 300 and the longitudinal adjustment mechanism 400 creates a two-dimensional adjustable space, allowing for easy adjustment to accommodate different frame sizes, different types of hinges, and even inlay requirements for different materials. Furthermore, the use of an ultrasonic inlay unit 200 that can precisely position the hinge allows for precise control of the hinge's position and direction, ensuring accurate vertical insertion of the hinge into the frame during the inlay process. This reduces hinge offset, improves production efficiency, and minimizes raw material waste.

[0036] refer to Figure 2 and Figure 3 The lateral adjustment mechanism 300 includes a first driving member 310, a first lead screw 320, a first moving block 330, and a first annular block 340. The first driving member 310 is mounted on the support frame 100. The output end of the first driving member 310 is connected to one end of the first lead screw 320, and the other end of the first lead screw 320 is rotatably connected to the support frame 100. The first moving block 330 is threadedly connected to the first lead screw 320. The first annular block 340 is sleeved on the surface of the support frame 100, and the moving block is connected to the first annular block 340. Micrometer-level adjustment is achieved through the transmission of the first lead screw 320, meeting the positioning requirements of small-sized eyeglass workpieces. The combination of the first annular block 340 and the support frame 100 limits wobbling and ensures smooth movement. The first driving member 310 directly drives the first lead screw 320, which has a simple structure and supports automatic control. It can be adapted to the lateral position adjustment of different sized eyeglass frames, improving the applicability of the equipment.

[0037] refer to Figure 2 and Figure 3The support frame 100 is provided with a guide groove 350, and the inner wall of the first annular block 340 is provided with a guide block 360 that works with the guide groove 350. The guide block 360 is inside the guide groove 350. After the guide block 360 is embedded in the guide groove 350, the two form a "mechanical engagement" rather than just relying on the inner surface of the annular block to fit against the support frame 100. During vibration, the annular block is less likely to have a "relative displacement" with the support frame 100, reducing the positional shift caused by vibration transmission.

[0038] refer to Figure 2 and Figure 3 The longitudinal adjustment mechanism 400 includes a support member 410, a second drive member 420, a second lead screw 430, a second moving block 440, and a second annular block 450. The support member 410 is mounted on the first annular block 340, and the second drive member 420 is mounted on the top of the support member 410. The output end of the second drive member 420 is connected to one end of the second lead screw 430, and the other end of the second lead screw 430 is rotatably connected to the inner wall of the support member 410. The second moving block 440 is threaded to the second lead screw 430. The second lead screw 430 is connected to the second annular block 450, and the second annular block 450 is slidably connected to the support member 410. The second annular block 450 is sleeved on the surface of the support member 410. When the second lead screw 430 is driven to rotate by the second driving member 420, the second moving block 440 achieves "uniform speed and equal distance" longitudinal movement through thread engagement, avoiding "displacement overshoot" caused by air pressure fluctuations in the traditional "cylinder push", thereby ensuring that the pressing depth of the welding head 240 needs to be controlled when the eyeglass hinge is inlaid.

[0039] refer to Figure 3 The support member 410 has a sliding groove 460 for guiding the second annular block 450, and one side of the annular block is located in the sliding groove 460. The sliding groove 460 runs longitudinally through the support member 410. When the embedded part of the annular block slides along the groove, the trajectory is strictly limited by the direction of the groove, ensuring that no matter what height it is adjusted to, the movement trajectory of the second annular block 450 is always parallel to the longitudinal axis, avoiding "spiral offset".

[0040] refer to Figure 4 and Figure 5The ultrasonic embedding unit 200 includes a frame 210, an ultrasonic transducer 220, a spring plate 230, and a welding head 240. The frame 210 is mounted on the second annular block 450, the ultrasonic transducer 220 is mounted on the inner wall of the frame 210, and the spring plate 230 is disposed between the welding head 240 and the ultrasonic transducer 220. The welding head 240 is connected to the ultrasonic transducer 220. The frame 210 is responsible for overall fixation and can support the ultrasonic transducer 220 and the welding head 240, preventing overall displacement during vibration. The ultrasonic transducer 220 is the energy source. The welding head 240 acts directly on the workpiece. The spring plate 230 undertakes the auxiliary function of "elastic buffering + pressure compensation" - there are no redundant parts, the structure is simple, and assembly and maintenance are convenient.

[0041] refer to Figure 4 and Figure 5 The ultrasonic inlay unit 200 also includes a drive motor 260 for driving the ultrasonic inlay unit 200 to work. The drive motor 260 is mounted on the top of the ultrasonic inlay unit 200. The drive motor 260 needs to provide power to the core moving parts of the ultrasonic inlay unit 200. The top-mounted layout can shorten the power transmission distance.

[0042] refer to Figure 4 and Figure 5 The welding head 240 is equipped with a hinge positioning head 250 for ultrasonic mounting and positioning of the eyeglass hinge; the hinge positioning head 250 always "holds" the hinge during the mounting process, and the hinge will not shift even under high-frequency vibration and pressure, ensuring that the ultrasonic energy is fully applied to the contact surface between the hinge and the frame, and ensuring the bonding strength.

[0043] The implementation principle of this application embodiment is as follows: In implementation, according to the change of the eyeglass frame, the first driving member 310 on the horizontal adjustment mechanism 300 is activated. The first driving member 310 drives the first lead screw 320 to rotate, the first lead screw 320 drives the first moving block 330 to move, the first moving block 330 drives the first annular block 340 to move, the moving block drives the vertical adjustment mechanism 400 to move, and the vertical adjustment mechanism 400 drives the ultrasonic inlay unit 200 to move, so that the ultrasonic inlay unit 200 moves to the horizontal coordinate position where the hinge needs to be inlaid. Then, the second driving member on the vertical adjustment mechanism 400 is activated. The second driving component 420 drives the second lead screw 430 to rotate, the second lead screw 430 drives the second moving block 440 to move, the second moving block 440 drives the second annular block 450 to move, and the second annular block 450 drives the ultrasonic inlay unit 200 to move, so that the welding head 240 on the ultrasonic inlay unit 200 performs ultrasonic welding with the hinge component on the eyeglass frame, which facilitates the use of the user, allows for precise control of the hinge position and direction, and can accurately insert the hinge vertically into the frame during the inlay process, reducing hinge offset, improving production efficiency, and reducing waste of raw materials.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
