Abstract
Description
Technical Field
[0001] This invention relates to the field of smart glasses manufacturing equipment technology, specifically to a tooling for locking screws on the hinges of smart glasses frames. Background Technology
[0002] Currently, in order to reduce the weight of smart glasses, manufacturers have extremely high requirements for the weight of metal components. For example, the metal structure of the frame hinge is gradually being simplified to achieve weight reduction. Some manufacturers even split the hinge axis in two to free up space in the middle section for the wiring between the temple and the frame, thus reducing weight.
[0003] Therefore, to achieve a movable hinge for the frame hinge, screws need to be tightened into the threaded holes aligned on both the upper and lower ends of the frame hinge. This requires precise positioning of the smart glasses frame hinge, followed by the use of a positioning and threading screw machine to quickly align the screws with the threaded holes. The screwing and tightening of the smart glasses frame hinge and screws can then be completed manually or automatically. Therefore, it is necessary to design a screw-tightening fixture that precisely positions the smart glasses and the frame and temple hinges to be screwed, and facilitates the quick insertion of screws into the threaded holes on both the upper and lower ends of the hinge. This fixture should be able to quickly tighten the screws on both the upper and lower ends of the hinge, meeting the production needs of mass-producing smart glasses hinge screws. Summary of the Invention
[0004] The problem this invention aims to solve is: addressing the production requirement of precisely, conveniently, and quickly tightening screws at the connection between the frame hinge and temple hinge of existing smart glasses. This invention proposes a screw-tightening fixture to improve the standardization of the screw-tightening process for smart glasses hinges, protect the appearance of the temples and frames during screw-tightening, and meet the production needs of mass-produced smart glasses hinge screw-tightening.
[0005] The technical solution adopted to solve the above problems is:
[0006] A screw-locking fixture for the hinge of a smart glasses frame is proposed, including:
[0007] A flip-up base is provided, with support plates on both the front and rear sides. A flip-up shaft is sleeved through the center of the support plates via a bearing.
[0008] A flipping platform, which mates with the flipping shaft, positions and supports the frame and temples in a fully extended state. The upper surface of the flipping platform is provided with a frame hinge positioning block, a bridge positioning block, a temple positioning block, a hinge seat, and a locking block for positioning the smart glasses.
[0009] The frame hinge positioning block is provided with a frame contour groove that fits the outer and lower surfaces of the frame; the nose bridge positioning block is provided with a nose bridge contour groove that fits the lower surface of the nose bridge, for fully positioning the frame structure; and the temple positioning block is provided with a temple contour groove that fits the outer and lower surfaces of the temple.
[0010] An angled clamping assembly is provided, which pushes and clamps the inner surfaces of the frame housing and temples on the inner side of the frame hinge. The angled clamping assembly includes a push base connected to the flipping platform, two side guide rod and sleeve assemblies, a push block, a push rod, and a flipping wrench.
[0011] The push block is connected by guide rod and sleeve assemblies on both sides and is limited to oblique linear sliding. A push rod is connected in the middle of the push block, and a spring is sleeved between the push block and the push seat. The oblique extension and retraction of the push block is controlled by a flip wrench connected to the other end of the push rod. A frame oblique push head is provided at the end of the push block that contacts the frame housing, and a temple oblique push head is provided at the end of the push block that contacts the temple. Under the action of spring force, the temple oblique push heads continuously maintain pressure on the frame housing.
[0012] The pressure plate is movably hinged to the hinge seat. The pressure plate has an elastic locking hook that cooperates with the locking block set on the flipping platform. The inner surface of the pressure plate is provided with a nose bridge pressure block, a hinge pressure block, and a temple pressure block that fit and press against the frame and temples of the smart glasses to be positioned. It also has a through-taper sleeve that cooperates with the forward threaded holes of the screws to be locked, which are aligned with the frame hinge and temple hinge.
[0013] The through-feed tap sleeve penetrates the pressure plate, and has an inverted conical through hole in the center to facilitate the insertion of the screw. The inverted conical through hole is directly opposite the center of the threaded hole.
[0014] The underside of the flipping platform is provided with a reverse through tap sleeve facing the reverse threaded hole of the locking screw. The reverse through tap sleeve has the same structure as the forward through tap sleeve, and its inverted conical through hole faces the center of the reverse threaded hole.
[0015] Furthermore, the nose bridge pressing block, hinge pressing block, and temple pressing block are respectively pressed against the upper surface of the nose bridge of the frame, the upper surface of the hinge shell on one side of the frame, and the upper surface of the temple.
[0016] Furthermore, the nose bridge pressing block includes a soft nose bridge pressing head and a nose bridge pressing seat, and the nose bridge pressing seat is fastened to the positioning groove opened on the inner surface of the pressing plate by a connector.
[0017] Furthermore, the hinge pressure block includes a soft hinge pressure head, a spring, and a hinge sealing plate. The hinge pressure head is provided with a stepped platform, which is fitted with a countersunk hole in the pressure plate. A spring is sleeved inside the hinge pressure head, and the end of the spring is held against the hinge sealing plate. The hinge sealing plate and the pressure plate are fastened together by a connector, thereby ensuring that the hinge pressure head keeps pressing the hinge shell of the mirror frame with elastic force.
[0018] Furthermore, the temple pressing block includes a soft temple pressing head and a temple pressing base, and the temple pressing base is fastened to the positioning groove opened on the inner surface of the pressing plate by a connector.
[0019] Furthermore, the front and rear faces of the flipping platform are provided with limiting protrusions. The limiting protrusions stop when they contact the upper face of the support plate. The positions where the limiting protrusions contact the left and right sides of the support plate are used as the limiting positions of the front and back faces of the flipping platform.
[0020] Furthermore, the limiting protrusion on the front side of the flipping platform is provided with a locking block. The locking block cooperates with the elastic locking hook provided on the front end face of the support plate to lock and position the flipping platform after it has been flipped.
[0021] Furthermore, the flipping platform is provided with clearance holes at the positions of the frame and temples of the smart glasses that are positioned and locked.
[0022] Furthermore, the frame contour groove is provided with a lens avoidance groove to protect the protruding lens of the smart glasses camera module, and the temple contour groove is provided with an icon avoidance groove to protect the logo on the outer side of the temple.
[0023] The beneficial effects of the technical solution of this invention are:
[0024] 1. This smart glasses frame hinge screw-locking fixture uses a frame hinge positioning block and a temple positioning block to position and support the temples and frame of the smart glasses to be screwed using a contoured groove structure. It also works with an oblique clamping component, a bridge clamping block, a hinge clamping block, and a temple clamping block to position and clamp the inner and upper surfaces of the frame hinge and temple, thus fully ensuring the positioning accuracy of the screw-locking screw at the connection between the frame hinge and the temple hinge.
[0025] 2. By using the forward and reverse tap sleeves, the screw is precisely aligned with the forward and reverse threaded holes of the screw to be locked, thus meeting the needs of high-precision screw insertion.
[0026] 3. By utilizing the rotational cooperation between the flipping platform and the flipping base, the forward and reverse tap sleeves can be alternately flipped 180 degrees to the upper end face. Manual or robotic personnel can easily insert screws from top to bottom into the inverted conical holes of the forward and reverse tap sleeves. Then, the screws are tightened by an automatic screw machine to complete the hinge assembly. Attached Figure Description

[0041] Please see Figure 1 This embodiment proposes a screw-locking fixture for the hinge of a smart glasses frame.
[0042] The fixture includes a flip base 1, with support plates on the front and rear sides of the flip base 1. A flip shaft 16 is sleeved through the center of the upper end of the support plate via a bearing, and a stop platform is provided on both sides of the upper end of the support plate to fit the flip platform 2.
[0043] See Figure 1 and Figure 2 The tooling includes a flipping platform 2 that fits into the flipping shaft 16. The flipping platform 2 positions and supports the eyeglass frame 20 and temple 19 in a fully extended state. The upper surface of the flipping platform 2 is provided with a frame hinge positioning block 17, a nose bridge positioning block 13, a temple positioning block 5, a hinge seat 12, and a locking block 4 for positioning the smart glasses.
[0044] Specifically, see Figure 1 , Figure 3 , Figure 4 and Figure 6 The frame hinge positioning block 17 is provided with a frame contour groove that fits the outer and lower surfaces of the frame. The nose bridge positioning block 13 is provided with a nose bridge contour groove 131 that fits the lower surface of the nose bridge, which is used to fully position the frame structure. The temple positioning block 5 is provided with a temple contour groove 6 that fits the outer and lower surfaces of the temple 19. After the three sets are fully fitted, the positioning and support of the smart glasses temple 19 and the glasses frame 20 are completed.
[0045] See Figure 3 , Figure 4 , Figure 5 and Figure 6 The tooling includes an oblique clamping assembly 14, which pushes and clamps the inner surface of the frame housing and the inner surface of the temple 19 on the inner side of the frame hinge 21. The oblique clamping assembly 14 includes a push seat 142 connected to the flipping platform 2, two side guide rod sleeve assemblies, a push block 141, a push rod, and a flipping wrench 143.
[0046] As a further solution to this embodiment, see [reference]. Figure 3 and Figure 5 The push block 141 is connected by guide rod and guide sleeve assemblies on both sides and is limited to oblique linear sliding. The push block 141 is connected to the middle of the push rod. A spring is sleeved between the push block 141 and the push seat 142. The oblique extension and retraction of the push block 141 is controlled by a flip wrench 143 connected to the other end of the push rod. The flip wrench 143 is movably hinged to the push rod. The flip wrench 143 is provided with an offset right angle block. By selecting different right angle sides to fit with the push seat 142, the oblique extension and retraction distance of the push rod can be controlled and adjusted. A frame oblique push head 1411 is provided at the end of the pressing block that contacts the frame housing, and a temple oblique push head 1412 is provided at the end of the temple that contacts the temple 19. Under the action of spring force, the temple oblique push head 1412 continuously maintains the pressure on the frame housing.
[0047] See Figure 1 and Figure 2 The tooling also includes a pressure plate 9 that is movably hinged to the hinge seat 12. The pressure plate 9 is equipped with an elastic locking hook 3 that cooperates with the locking block 4 provided on the flipping platform 2. The inner surface of the pressure plate 9 is provided with a nose bridge pressure block 11, a hinge pressure block 8, and a temple pressure block 7 that fit and press against the eyeglass frame 20 and temple 19 of the smart glasses to be positioned, as well as a through tap sleeve 10 that cooperates with the forward threaded hole of the screw 22 to be locked that is aligned with the eyeglass frame hinge 21 and the temple hinge.
[0048] The particularly important technical solution is, see [reference] Figure 4 , Figure 6 and Figure 9The through-taper sleeve 10 passes through the pressure plate 9, and has an inverted conical through hole 181 in the center to facilitate the insertion of the screw 22. The inverted conical through hole 181 is directly opposite to the center of the threaded hole and is close to the frame hinge 21.
[0049] Specifically, see Figure 4 and Figure 9 The lower surface of the flipping platform 2 is provided with a reverse through tap sleeve 18 facing the reverse threaded hole of the locking screw 22. The reverse through tap sleeve 18 is positioned by the taper sleeve bracket 23 and has the same structure as the forward through tap sleeve 10. Its inverted conical through hole 181 faces the center of the reverse threaded hole and is close to the bottom of the frame hinge 21.
[0050] By using the forward tap sleeve 10 and the reverse tap sleeve 18, the screw 22 is precisely aligned with the forward and reverse threaded holes of the screw 22 to be locked, thus meeting the high-precision threading requirements of the screw 22.
[0051] Further implementation plans are as follows, see [link / reference] Figure 3 , Figure 4 The nose bridge pressing block 11, hinge pressing block 8 and temple pressing block 7 are respectively pressed against the upper surface of the nose bridge of the frame, the upper surface of the hinge shell on one side of the frame, and the upper surface of the temple 19.
[0052] More specifically, the nose bridge pressing block 11 includes a soft nose bridge pressing head and a nose bridge pressing seat, and the nose bridge pressing seat is fastened to the positioning groove 902 opened on the inner surface of the pressing plate 9 by bolts.
[0053] Further implementation plans are as follows, see [link / reference] Figure 3 , Figure 4 , Figure 5 and Figure 6 The hinge pressure block 8 includes a soft hinge pressure head, a spring, and a hinge sealing plate. The hinge pressure head is provided with a stepped platform, which is fitted with a countersunk hole 901 on the pressure plate 9. A spring is fitted inside the hinge pressure head, and the end of the spring is held against the hinge sealing plate. The hinge sealing plate and the pressure plate 9 are fastened together by a connector, thereby ensuring that the hinge pressure head presses against the hinge shell of the mirror frame with elasticity.
[0054] A further embodiment is that the temple pressing block 7 includes a soft temple pressing head and a temple pressing seat, and the temple pressing seat is fastened to the positioning groove 902 opened on the inner surface of the pressing plate 9 by bolts.
[0055] As a further technical solution of this embodiment, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 7The front and rear faces of the flipping platform 2 are provided with limiting protrusions 202. The limiting protrusions 202 stop when they contact the upper face of the support plate. The stopping platforms where the limiting protrusions 202 contact the left and right sides of the support plate are used as the limiting positions of the front and back faces of the flipping platform 2.
[0056] A further technical solution is to refer to... Figure 2 and Figure 8 The limiting protrusion 202 on the front side of the flipping platform 2 is provided with a locking block 15. The locking block 15 cooperates with the elastic locking hook 3 provided on the front end of the support plate to lock and position the flipping platform 2 after flipping, so as to accurately put the screw 22 on the smart glasses that are locked and positioned, and carry out the screw 22 locking work.
[0057] Further implementation plans are as follows, see [link / reference] Figure 3 The flipping platform 2 is provided with clearance holes 201 at the positions of the frame and temple 19 of the smart glasses that are positioned and locked.
[0058] Further implementation plans are as follows, see [link / reference] Figure 4 The frame contour groove is provided with a lens avoidance groove 171 to protect the protruding lens of the smart glasses camera module, and the temple contour groove 6 is provided with an icon avoidance groove 601 to protect the logo on the outside of the temple 19.
