Description

Technical Field

[0001] This invention relates to the field of eyeglass manufacturing technology, and more specifically to a shaping device for acetate eyeglasses. Background Technology

[0002] Acetate frames are stylish and easy to match with clothing. They combine the solidity of acetate with the texture of metal, reflecting individuality and style. The frame shape has both modern and classic features, with streamlined shapes and richly colored frames that achieve a perfect seamless integration, making them popular among consumers.

[0003] Currently, the main production technology for acetate eyeglasses involves extruding various colored flat profiles using an extruder, milling the eyeglass frame shape using a die milling machine, and then using the plasticity of the material to splice the nose pads and headstocks with chemical raw materials. After drying, the spliced ​​joints are milled, and after processing, they still need to be precisely finished by hand with a scraper.

[0004] The existing technical problem in the production of acetate eyeglass frames is that in order to adapt the frames to the curvature of the face, a bending process is required. Existing acetate eyeglass frame bending machines usually use two hemispherical elastic rubber modules for the upper mold device, and have clearances cut out at the positions of the nose pads and headpieces. The lower mold is a custom-made integral model based on the shape of the product.

[0005] The overall model can only process frames with small curvature (4-5 Base). For frames with large curvature (6-8 Base), a CNC engraving machine is needed to carve the upper and lower molds that perfectly match the shape of the outer surface of the glasses.

[0006] This type of equipment relies on prefabricated upper and lower molds. When it is necessary to produce differentiated products according to different user facial sizes, multiple molds must be prepared. Not only are the mold costs high, but the machine must also be stopped during production to replace the molds in order to meet the product specifications. It is also extremely inconvenient to use.

[0007] In particular, as acetate frames become increasingly prevalent in the fashion industry, the standardized specifications of mass-market eyeglasses are struggling to meet consumers' demands for personalized customization. Existing bending equipment, limited by mold costs, cannot perform customized production, which would result in extremely high production costs.

[0008] Today's consumers seek frames that perfectly match their facial dimensions and features, aiming for a more refined fit and comfortable wearing experience. Therefore, there is a need for acetate eyeglass molding equipment capable of customized production for individual consumers. This equipment would allow for more flexible frame adjustments to accommodate specific facial features (especially key dimensions affecting wearing comfort, such as nose bridge width, eye socket width, and facial curvature), while also reducing production costs and facilitating mass production and promotion. Summary of the Invention

[0009] In order to overcome the shortcomings of the above-mentioned technology, the present invention provides a shaping device for sheet metal eyeglasses.

[0010] The technical solution of the present invention: a shaping device for acetate eyeglasses, the device comprising an arc adjustment device, a frame adjustment device and a PLC controller, wherein the arc adjustment devices are arranged in pairs and a frame placement station is provided between the two arc adjustment devices, the arc adjustment device comprising a plurality of extrusion head mechanisms, a gear engagement mechanism, an advance and retreat platform and a base arranged side by side, the extrusion head mechanism comprising a first extrusion head, a push seat, a lifting platform, a first lead screw and a driven gear;

[0011] The first extrusion head includes a pre-formed arc end facing the frame and an insertion end. The push seat is provided with a slot end and a first wedge-shaped surface. The lifting platform is provided with a second wedge-shaped surface that slides with the first wedge-shaped surface and a lead screw hole. The first lead screw passes through the lead screw hole and rotates with the base. The driven gear is coaxially fixed with the first lead screw. A partition is provided between the base and the two adjacent lifting platforms.

[0012] The gear docking mechanism includes a drive gear, a gear sliding seat, a first transmission belt, a transmission belt motor, and a gear motor. The gear sliding seat is set on the advance and retreat platform and slides along the direction of the rows of several extrusion head mechanisms. The drive gear is rotatably set on the gear sliding seat. The gear motor is fixed on the gear sliding seat and is linked with the drive gear to drive the drive gear to rotate.

[0013] The advancing and retreating platform is equipped with a pair of pulleys. The first transmission belt is sleeved on the pulleys and fixedly connected to the gear sliding seat. The transmission belt motor is located inside the advancing and retreating platform, and its output shaft is linked with the pulleys to drive the gear sliding seat to slide to the position of each driven gear. The advancing and retreating platform is slidably mounted on the base, which is equipped with a drive cylinder. The drive cylinder pushes and pulls the advancing and retreating platform, causing the driving gear to approach and mesh with the driven gear. The first lead screw rotates with the driven gear to drive the lifting platform to move up and down.

[0014] Using the above technical solution, after measuring and obtaining the facial feature dimensions of the customized customer, such as the width of the bridge of the nose, the width of the eye socket, and the curvature of the cheek, the dimensions are calculated and compared with the mass-produced general-purpose frame material. For example, the bridge of the nose and the eye socket are compared with the general-purpose frame material to determine whether the general-purpose frame material is too wide or too narrow, and how much curvature the general-purpose frame material needs to be bent, so as to obtain the dimensional variables required for shaping.

[0015] In a measurement environment, existing facial capture technology can be used to set up targets on facial features and measure the dimensional relationships between the targets using facial capture equipment to obtain dimensional data for shaping.

[0016] After obtaining the dimensional data, the arc adjustment device is started by controlling the PLC controller. Under the operation of the gear docking mechanism, the advance and retreat table and the first transmission belt drive gear sliding seat pass through and approach each of the first lead screws one by one, so that the driving gear meshes with each driven gear in sequence.

[0017] During the meshing process, the gear motor is controlled to rotate a different number of revolutions for each driven gear, causing the lifting platforms on each first lead screw to make different stroke displacements. Due to the sliding fit between the second wedge-shaped surface of the lifting platform and the first wedge-shaped surface of the propulsion seat, the lifting platform, along the position of the first lead screw, will drive the propulsion seat to advance and retract to different depths.

[0018] This allows the first extrusion heads, which were originally in the same parallel row, to move forward or backward, forming a row of matching arc-shaped distributions according to the curvature of the face. In this way, the outline of the extrusion block formed by the parallel first extrusion heads can be adjusted in real time without the need for pre-made molds.

[0019] Meanwhile, because the first extrusion head and the push seat are detachable slot-connected structures, in addition to adjusting the curvature in the horizontal direction relative to the face, the vertical curvature of the face can also be adjusted by replacing the first extrusion head with different vertical curvatures.

[0020] By setting curvature adjustment devices on both sides of the frame, the curvature of the frame is shaped by adjusting and squeezing simultaneously from both sides.

[0021] A further feature of the present invention is that the curvature adjustment device further includes a pad cloth covering the pre-formed arc end of each first extrusion head. The pre-formed arc end is close to the edge of the adjacent first extrusion head and has an arc transition. The pad cloth is provided with a support rib corresponding to the gap at the arc transition between two adjacent first extrusion heads.

[0022] Using the above technical solution, after the first extrusion heads are staggered, a stepped transition is formed between adjacent parts. If directly extruded, corresponding indentations will be formed on the frame. Therefore, an arc transition is provided. However, indentations still exist at the arc transition, and a smooth, integral surface cannot be formed. Therefore, this invention provides a pad to cover the arc end of the first extrusion head. The elasticity and toughness of the pad fill the staggered transition, resulting in a flat surface, so that the surface of the frame after extrusion does not show traces of uneven extrusion. At the same time, the provided support ribs fill the indentations at the arc transition, making the transition area also filled, further enhancing the flatness of the pad surface. The pad can be made of composite materials such as fiber cloth and rubber pads.

[0023] A further feature of the present invention is that the gear sliding seat has an extended end, on which a gear shaft and a second transmission belt are rotatably mounted. The second transmission belt is sleeved with the gear shaft and the output shaft of the gear motor, respectively. The driving gear is coaxially fixed on the gear shaft.

[0024] By adopting the above technical solution, the driving gear can extend and mesh with the driven gear one by one.

[0025] A further feature of the present invention is that the frame adjustment device includes a frame base, a plurality of second lead screws, a lead screw motor, and a left nose bridge pressing member and a right nose bridge pressing member adapted to the contour of the nose bridge groove of the frame, a left nose bridge pressing member and a right nose bridge pressing member adapted to the contour of the inner circle of the frame, and an outer nose bridge pressing member adapted to the contour of the outer circle of the frame head.

[0026] The left and right nose bridge extrusion pieces, the left and right frame extrusion pieces, and the outer frame extrusion piece are all equipped with sliding blocks. Each sliding block has a lead screw hole. The frame base is equipped with a groove that fits the frame and a slider groove corresponding to the position of each extrusion piece. Each sliding block is respectively set in the slider groove for sliding engagement. The several second lead screws are respectively inserted into the lead screw holes and are linked with the lead screw motor to drive each extrusion piece to move closer to or away from the frame.

[0027] Using the above technical solution, under the action of each lead screw motor, the left and right nose bridge squeezing components either expand outwards from the nose bridge groove of the frame to increase the width of the nose bridge groove; or drive the left frame squeezing component to squeeze towards the nose bridge groove, cooperating with the nose bridge squeezing component to narrow the width of the nose bridge groove; or the left and right frame squeezing components expand outwards to increase the width of the frame; or the right frame squeezing component cooperates with the outer frame squeezing component to narrow the width of the frame.

[0028] This achieves the purpose of adjusting the bridge of the nose and the size of the frame. Based on this principle, it is possible to set compression components in the vertical direction relative to the frame, or compression components corresponding to other curved parts, to expand or narrow them, which will not be repeated here.

[0029] A further feature of the present invention is that the shaping equipment also includes a turntable, and a grinding machine, an ultrasonic cleaner, and a heating device disposed on the turntable.

[0030] By adopting the above technical solution, the turntable allows operators to complete all steps at a single workstation. Heating devices, such as industrial electric furnaces, preheat the eyeglass frames to prepare them for subsequent shaping and extrusion. A grinding machine polishes the extruded frames, and an ultrasonic cleaner cleans them. After cleaning, the shaping process is complete.

[0031] The beneficial effects of this invention are: No custom molds or mold replacements are required. Real-time measurement of the user's facial features drives the structural contour of the curvature adjustment device, resulting in a contour distribution that fits the face, and the frame is shaped by compression. When further vertical curvature adjustments are needed, different shaped first extrusion heads can be quickly disassembled and assembled for targeted adjustments. Compared to the practicality of producing a complete mold, the first extrusion head has a simple structure, low production cost, and can adapt to diverse, customized, and small-scale production and promotion needs.

Detailed Implementation

[0043] like Figure 1-10 As shown, a shaping device for acetate eyeglasses includes an arc adjustment device 1, a frame adjustment device 2, and a PLC controller. The arc adjustment devices 1 are arranged in pairs, and a frame 5 placement station is provided between the two arc adjustment devices 1. The arc adjustment device 1 includes several extrusion head mechanisms, gear docking mechanisms, advance and retreat platforms 11, and a base 12 arranged side by side. The extrusion head mechanism includes a first extrusion head 13, a push seat 14, a lifting platform 15, a first lead screw 16, and a driven gear 17.

[0044] The first extrusion head 13 includes a pre-formed arc end 131 facing the frame 5 and an insertion end 132. The push seat 14 is provided with a slot end 141 and a first wedge surface 142. The lifting platform 15 is provided with a second wedge surface 151 that slides with the first wedge surface 142 and a lead screw hole. The first lead screw 16 passes through the lead screw hole and rotates with the base 12. The driven gear 17 is coaxially fixed with the first lead screw 16. A partition 121 is provided between the base 12 and the two adjacent lifting platforms 15.

[0045] The gear docking mechanism includes a drive gear 31, a gear sliding seat 32, a first transmission belt 33, a transmission belt motor, and a gear motor 311. The gear sliding seat 32 is disposed on the advance and retreat platform 11 and slides along the direction of the rows of several extrusion head mechanisms. The drive gear 31 is rotatably disposed on the gear sliding seat 32. The gear motor 311 is fixed on the gear sliding seat 32 and is linked with the drive gear 31 to drive the drive gear 31 to rotate.

[0046] The advancing / retreating platform 11 is provided with a pair of pulleys 111. The first transmission belt 33 is sleeved on the pulleys 111 and fixedly connected to the gear sliding seat 32. The transmission belt motor is set inside the advancing / retreating platform 11, and its output shaft is linked with the pulleys 111 to drive the gear sliding seat 32 to slide to the position of each driven gear 17. The advancing / retreating platform 11 is set on the base 12 for sliding engagement. The base 12 is provided with a drive cylinder 122. The drive cylinder 122 pushes and pulls the advancing / retreating platform 11, driving the driving gear 31 to approach and mesh with the driven gear 17. The first lead screw drives the lifting platform 15 to move up and down as the driven gear 17 rotates.

[0047] After measuring the facial features of the customized customer, such as the width of the bridge of the nose, the width of the eye socket, and the curvature of the cheek, the dimensions are compared with those of the mass-produced general-purpose frame material 5. For example, the dimensions of the general-purpose frame material 5 are compared with those of the bridge of the nose and the eye socket to determine whether they are too wide or too narrow, and how much curvature the general-purpose frame material 5 needs to be bent, thus obtaining the dimensional variables required for shaping.

[0048] In a measurement environment, existing facial capture technology can be used to set up targets on facial features and measure the dimensional relationships between the targets using facial capture equipment to obtain dimensional data for shaping.

[0049] After obtaining the dimensional data, the arc adjustment device 1 is started by controlling the PLC controller. Under the operation of the gear docking mechanism, the advance and retreat table 11 and the first transmission belt 33 drive the gear sliding seat 32 to pass through and approach each of the first lead screws 16 one by one, so that the driving gear 31 meshes with each of the driven gears 17 in sequence.

[0050] During the meshing process, the gear motor 311 is controlled to rotate a different number of revolutions for each driven gear 17, causing the lifting platforms 15 on each first lead screw 16 to make different stroke displacements. Due to the sliding engagement between the second wedge-shaped surface 151 of the lifting platform 15 and the first wedge-shaped surface 142 of the push seat 14, the lifting platform 15 will be driven to advance and retract to different depths along the position of the first lead screw 16.

[0051] This allows the first extrusion heads 13, which were originally in the same parallel row, to move forward or backward, forming a row of adapted arc-shaped distributions according to the curvature of the face. In this way, the outline of the extrusion block formed by the first extrusion heads 13 arranged side by side can be adjusted in real time without the need for pre-made molds.

[0052] Meanwhile, since the first extrusion head 13 and the push seat 14 are detachable slot-connected structures, in addition to adjusting the curvature in the horizontal direction relative to the face, the vertical curvature of the face can also be adjusted by replacing the first extrusion head 13 with different vertical curvatures.

[0053] By setting curvature adjustment devices 1 on both sides of the frame 5, the curvature of the frame 5 is shaped by adjusting and squeezing simultaneously from both sides.

[0054] The curvature adjustment device 1 also includes a pad 4, which covers the pre-arc end 131 of each first extrusion head 13. The pre-arc end 131 is close to the edge of the adjacent first extrusion head 13 and has an arc transition. The pad 4 is provided with a support rib 41 corresponding to the gap at the arc transition between two adjacent first extrusion heads 13.

[0055] After the first extrusion heads 13 are staggered, a stepped transition is formed between adjacent parts. If the extrusion is direct, a corresponding indentation will be formed on the frame 5. Therefore, an arc transition is provided. However, there is still a depression at the arc transition, and a smooth overall surface cannot be formed. Therefore, this invention provides a pad 4 to cover the arc end of the first extrusion head. The elasticity and toughness of the pad 4 fills the staggered transition, resulting in a flat surface, so that the surface of the frame 5 after extrusion does not show traces of uneven extrusion. At the same time, the provided support ribs 41 fill the depression at the arc transition, making the transition also filled, further enhancing the flatness of the pad 4 surface. The pad 4 can be made of composite materials such as fiber cloth and rubber pad.

[0056] The gear sliding seat 32 is provided with an extension end 321, on which a gear shaft 323 and a second transmission belt 322 are rotatably mounted. The second transmission belt 322 is sleeved with the gear shaft 323 and the output shaft of the gear motor 311 respectively. The driving gear 31 is coaxially fixed on the gear shaft 323.

[0057] This allows the driving gear 31 to extend and mesh with the driven gear 17 one by one.

[0058] The frame adjustment device 2 includes a frame base 21, several second lead screws 22, a lead screw motor, and a left nose bridge pressing member 23 and a right nose bridge pressing member 24 that are adapted to the contour of the nose bridge groove 51 of the frame, a left nose bridge pressing member 25 and a right nose bridge pressing member 26 that are adapted to the contour of the inner ring 52 of the frame, and an outer nose bridge pressing member 27 that is adapted to the contour of the outer ring on one side of the frame post.

[0059] The left and right nose bridge extrusion pieces, the left and right frame extrusion pieces, and the outer frame extrusion piece 27 are all equipped with sliding blocks. Each sliding block has a lead screw hole. The frame base 21 is equipped with a groove that fits the frame 5 and a slider groove corresponding to the position of each extrusion piece. Each sliding block is respectively set in the slider groove for sliding engagement. The plurality of second lead screws 22 are respectively inserted into each lead screw hole and are linked with the lead screw motor to drive each extrusion piece to move closer to or away from the frame 5.

[0060] Under the action of each lead screw motor, the left nose bridge pressing member 23 and the right nose bridge pressing member 24 either expand from the nose bridge groove of the frame 5 to both sides, increasing the width of the nose bridge groove; or drive the left frame pressing member 25 to press towards the nose bridge groove side, cooperating with the nose bridge pressing member to narrow the width of the nose bridge groove; or the left and right frame pressing members expand to both sides, increasing the width of the frame; or the right frame pressing member 26 cooperates with the outer frame pressing member 27 to narrow the width of the frame.

[0061] This achieves the purpose of adjusting the bridge of the nose and the size of the frame. Based on this principle, it is possible to uniformly set compression parts in the vertical direction relative to the frame 5, or compression parts corresponding to other curved parts, to expand or narrow them, which will not be repeated here.

[0062] The shaping equipment also includes a turntable 61, and a grinding machine, an ultrasonic cleaner, and a heating device mounted on the turntable 61.

[0063] The turntable 61, when rotated, allows operators to complete all steps at a single workstation. Heating devices, such as industrial electric furnaces, preheat the eyeglass frame material for subsequent shaping and extrusion. A grinding machine polishes the extruded frame 5, and an ultrasonic cleaner cleans it. After cleaning, the shaping process of the frame 5 is complete.

[0064] The beneficial effects of this invention are: No custom molds or mold replacements are required. Real-time measurement of the user's facial features drives the structural contour of the curvature adjustment device 1, resulting in a contour distribution that fits the face, and the frame 5 is then shaped by compression. When further vertical curvature adjustments are needed, different shapes of the first extrusion head 13 can be quickly disassembled and assembled for targeted adjustments. Compared to the practicality of producing a complete mold, the first extrusion head 13 has a simple structure, low production cost, and can adapt to diverse, customized, and small-scale production and promotion needs.
