Description

Technical Field

[0001] This invention relates to the field of rotating mirror bonding technology, and more particularly to a rotating mirror AA bonding assembly and bonding method. Background Technology

[0002] Currently, lenses are used in a variety of products, such as laptops, mobile phones, tablets, and LiDAR, but their structures and assembly methods differ. For example, the principle of LiDAR detecting the presence of objects in front is that the laser light emitted is reflected by a high-speed rotating mirror and then shines on the object being measured. The light is then reflected by the object and the rotating mirror back to the receiver. If there is no object, no light is reflected back, thus determining whether an object is present. The rotating mirror consists of a polyhedral frame and a lens that is attached to the surface of the frame. When the lens is attached to the frame surface, a rotating mirror AA attachment mechanism is used to adjust the position of the lens relative to the frame, ensuring that the angle and height of the lens are accurate in all directions after it is attached to the frame surface.

[0003] Currently, lens manufacturers utilize various rotating mirror AA bonding machines. For example, Chinese invention patent CN116251715A discloses a multi-channel LiDAR lens AA device. This device is used to assemble the LiDAR body and reflective lenses. The multi-channel LiDAR lens AA device includes a frame, an AA unit, an optical inspection mechanism, a glue application mechanism, and a curing mechanism. The AA unit includes an adjustment base and an AA transfer assembly. The adjustment base includes a rotation mechanism and a positioning mechanism located at the movable end of the rotation mechanism. The positioning mechanism is used to fix the LiDAR body. The AA transfer assembly includes an adjustment mechanism and a first clamping assembly located at the end of the adjustment mechanism. The first clamping assembly is used to clamp the reflective lenses. The optical inspection mechanism is located above the AA unit and is used to detect the laser emitted by the LiDAR body and reflected by the reflective lenses. If the patented AA bonding machine does not pre-treat the bonding surfaces of the lenses and frames, these surfaces are prone to contamination. While small contaminants can be aligned with the lens and frame position by the AA bonding mechanism, they can damage the adhesion, leading to quality issues during high-speed rotation. Larger contaminants cannot be aligned at all by the AA bonding mechanism. While the robotic arm positions the lenses and frames when retrieving them from the tray, misalignment occurs during the transfer of lenses to the AA bonding mechanism and during the transfer of frames to the spindle. The more transfers occur, the greater the accumulated misalignment, resulting in inaccurate final bonding of the lenses and frames. Summary of the Invention

[0004] In view of this, the present invention aims to provide a rotating lens AA bonding assembly, which employs a lens cleaning device and a frame cleaning device. Before bonding, the lens and frame are cleaned separately by the lens cleaning device and the frame cleaning device to remove contaminants from the lens and frame. A rotating camera is used to obtain the coordinate position of the lens, a frame detection device detects the center coordinates of the frame, a collimator detects the deflection angle of the lens, and an angle adjustment component and a tilting mechanism adjust the angle of the lens. This solves the problems of not pre-treating the bonding surfaces of the lens and frame, which easily leads to contamination of the bonding surfaces and quality problems, the lens shifting during the robot arm's transfer of the lens to the lens AA bonding mechanism, and the frame shifting during the robot arm's transfer of the frame to the main shaft. The more transfers, the greater the cumulative shift, resulting in inaccurate positioning of the lens and frame when finally bonded together.

Detailed Implementation

[0086] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0087] In this invention, the terms "first," "second," "upper," and "lower," etc., are used for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," "upper," or "lower" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. Where the technical solutions of the embodiments can be combined, they are all within the scope of protection claimed by this invention.

[0088] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0089] like Figures 1 to 3As shown, a rotating lens AA bonding assembly includes: a lens bonding device 100, a frame fixing device 200, and a transfer device 300. The lens bonding device 100 includes: a lens fixing device 110, a lens loading device 120, and a lens cleaning device. The lens fixing device 110 includes: a lens fixing mechanism 111 for fixing the lens, and the lens fixing mechanism 111 is movable along the X-axis. The lens loading device 120 is used to receive or output the lens. The frame fixing device 200 includes: a frame fixing device 210, a frame loading device 220, a frame cleaning device 250, an adhesive dispensing device 240, and a frame detection device 230. Figure 10 As shown, the frame fixing device includes: a frame fixing mechanism including a fixing shaft 211, on which the frame is fixed, and the fixing shaft 211 is movable and rotatable along the Y-axis. The lens fixing mechanism 111 moves along the X-axis via the movement of the fixing shaft 211 along the Y-axis, causing the lens and the frame to fit together. A frame loading device 220 is used to receive or output the frame. An adhesive dispensing device 240 is used to dispense adhesive onto the frame. A frame detection device 230 detects the center coordinates of the frame. The transfer device 300 includes: a transfer device and a base plate. The transfer device is movable along the X-axis between the lens bonding device 100 and the frame fixing device 200, and picks up and transfers the lens and the frame. The lens bonding device 100, the frame fixing device 200, and the transfer device 300 are fixed to the base plate.

[0090] Lenses are output through the lens loading device 120, picked up by the transfer device, and then the contaminants on the lenses are removed by the lens cleaning device and fixed on the lens fixing device 110.

[0091] The frame fixing device also includes: a Y-axis drive assembly 214, a driver 213, and a frame detection sensor 212. The Y-axis drive assembly 214 drives the fixed shaft 211 to move along the Y-axis direction. The driver 213 is movably mounted on the Y-axis drive assembly 214 along the Y-axis direction, and the fixed shaft 211 is mounted on the driver 213. Driven by the driver 213, the fixed shaft 211 rotates around the Y-axis. The frame detection sensor 212 detects whether the frame is mounted on the fixed shaft 211. The driver 213 drives the fixed shaft 211 to rotate, making the contact surface of the frame parallel to the lens. The Y-axis drive assembly 214 drives the fixed shaft 211 to move along the Y-axis direction, moving the frame to a position corresponding to the lens. The X-axis drive assembly drives the fixing member 1111 to move along the first direction of the X-axis towards the frame, attaching the lens to the frame.

[0092] like Figure 11As shown, the dispensing device 240 includes a dispensing needle 241, which dispenses adhesive onto the mating surface of the eyeglass frame. The dispensing device 240 also includes a dispensing image acquisition unit 243 and a laser displacement sensor 242. When mounting the eyeglass frame on the fixed shaft 211, the first mating surface on the side of the frame should theoretically be horizontal, but it may deflect during movement. After fixing the frame to the fixed shaft 211, before dispensing adhesive, the laser displacement sensor 242 scans the first mating surface and measures the deflection angle between the first mating surface and the horizontal plane. The frame fixing mechanism controls the rotating fixed shaft 211 to rotate until the first mating surface of the frame is completely horizontal based on the measured deflection angle. Then, the laser displacement sensor 242 scans each bonding surface (the rotating fixed shaft 211 drives the lens frame to rotate each bonding surface to the horizontal in sequence. The rotating fixed shaft 211 is controlled by a DD motor, which has high rotational accuracy). It measures the height of each bonding surface (theoretically, the height of each bonding surface is the same, but it may be different due to processing errors, etc. If the bonding surface is too high, if the lens travel is not adjusted when bonding the lens, the lens may be completely crushed by the glue and cannot reach the preset travel position). Based on the height value of each bonding surface, the subsequent glue dispensing and lens bonding travel is adjusted to improve bonding accuracy and prevent poor bonding.

[0093] Eyeglass frames are output via frame loading device 220, picked up by transfer device, and cleaned by frame cleaning device 250. The frame's center coordinates are then obtained by frame detection device 230. Based on these coordinates, the frame is fixed to fixed shaft 211, and adhesive is applied to the bonding surface. Lens fixing mechanism 111 moves along the X-axis toward fixed shaft 211, while fixed shaft 211 moves along the Y-axis toward lens fixing device, thus bonding the lens to the frame.

[0094] The rotating mirror AA bonding assembly described above employs a lens cleaning device and a frame cleaning device 250. Before bonding, the lens and frame are cleaned separately by these devices to remove contaminants. A rotating camera acquires the coordinate position of the lens, a frame detection device 230 detects the center coordinates of the frame, a collimator 1121 detects the deflection angle of the lens, and an angle adjustment component and a tilting mechanism 114 adjust the lens angle. This pre-treatment of the bonding surfaces of the lens and frame removes contaminants, improving quality. It also corrects the offsets caused by the robotic arm transferring the lens to the lens AA bonding mechanism and by the robotic arm transferring the frame to the main shaft, reducing accumulated offsets and ensuring accurate positioning when the lens and frame are finally bonded together.

[0095] Furthermore, such as Figure 4As shown, the lens fixing mechanism 111 includes: a fixing member 1111, a curing member 1112, an angle adjustment assembly, and a lens fixing detection assembly 112. The fixing member 1111 has an adsorption hole communicating with a vacuum device, through which the lens is adsorbed at the end of the adsorption hole. The curing member 1112 is disposed on both sides of the fixing member 1111, and the direction of light emitted by the curing member 1112 is parallel to the lens surface. The angle adjustment assembly includes a horizontal angle adjuster 1114 and a pitch angle adjuster 1113. The horizontal angle adjuster 1114 adjusts the angle of rotation of the fixing member 1111 around the Z-axis, and the pitch angle adjuster 1113 adjusts the angle of rotation of the fixing member 1111 around the Y-axis. Figure 5 As shown, the lens fixing and detection assembly 112 includes a collimator 1121 and a corner image acquisition device 1122. A through hole is also provided on the fixing member 1111. The collimator 1121 is used to adjust the outgoing light rays to coincide with or be parallel to the axis of the through hole.

[0096] During the bonding operation, the lens is fixed to the fixing surface of the fixing member 1111. Preferably, the fixing member 1111 has an adsorption hole penetrating through the fixing surface, and the adsorption hole is connected to an air extraction device. Air extraction is performed when fixing the lens to adsorb it onto the fixing surface. In one embodiment, the horizontal angle adjuster 1114 is a turntable that rotates around the Z-axis. A pitch angle adjuster 1113 is provided on the turntable. The pitch angle adjuster 1113 includes a concave part and a convex part. The surface of the concave part opposite to the convex part is a concave spherical surface, and the surface of the convex part opposite to the concave part is a convex spherical surface that mates with the concave spherical surface. Adjusting the rotation of the convex part around the Y-axis adjusts the pitch angle of the bonding mechanism. After the lens is fixed, the state of the fixing member 1111 is detected by a collimator 1121 to ensure that the light emitted by the collimator 1121 coincides with or is parallel to the axis of the through hole, ensuring that the position and angle of the lens meet the bonding requirements. If the fit is not met, adjust the state of the fastener 1111 using the angle adjustment component.

[0097] Furthermore, the lens fixing device 110 also includes: a tilting mechanism 114 and a lens transfer mechanism 113. For example... Figure 8 As shown, the yaw mechanism 114 includes: a mounting plate 1142, the lens fixing mechanism 111 is fixed on the mounting plate 1142, the mounting plate 1142 is provided with a rotation center, the rotation center is located at one end of the mounting plate 1142 along the X-axis direction, and the other end of the mounting plate 1142 away from the rotation center in the X-axis direction rotates around the rotation center.

[0098] The tilting mechanism 114 is used to fine-tune the angle of the fixing member 1111. Specifically, in one embodiment, the tilting mechanism 114 includes: a tilting track 1144, a mounting plate 1142, and an angle fine adjuster 1145. The tilting track 1144 is arc-shaped and is fixed to the base with the axis of the rotating shaft 1141 as the center. The lens fixing mechanism 111 is fixed to the mounting plate 1142. A sliding structure that cooperates with the tilting track 1144 is provided on the surface of the mounting plate 1142 relative to the base. A push block 1143 is provided on the mounting plate 1142, and the push block 1143 protrudes from the edge of the mounting plate 1142 near the angle fine adjuster 1145. The angle fine adjuster 1145 is fixed to the base, and two micrometers 11451 are provided opposite to each other on the angle fine adjuster 1145. A rotating shaft 1141 is connected to one end of the mounting plate 1142 away from the angle fine adjuster 1145. The mounting plate 1142 rotates around the rotating shaft 1141. The other end of the mounting plate 1142 is limited by an arc-shaped track. The yaw track 1144 and the rotating shaft 1141 prevent the mounting plate 1142 from moving during rotation. A sliding structure is provided on the lower surface of the mounting plate 1142 to cooperate with the track. On the mounting plate 1142, near the angle fine adjuster 1145, there are multiple screw holes arranged in an arc shape, and the arc formed by each screw hole is centered on the center of the rotating shaft 1141. The angle fine adjuster 1145 is provided with bolt through holes that cooperate with the screw holes. The bolt through holes are preferably elongated arc-shaped holes, and at least two bolt through holes are provided. After rotating the mounting plate 1142 to the appropriate position, fix the angle fine adjuster 1145 in the corresponding position, clamp the push block 1143 from both sides of the push block 1143 with two opposing micrometers 11451, and make a small adjustment to the angle of the lens bonding device by fine adjusting the micrometers 11451.

[0099] like Figure 6 and Figure 7 As shown, the lens transfer mechanism 113, fixed on the mounting plate 1142, includes a transfer platform 1131 and a alignment component 1132. The transfer platform 1131 is connected to the vacuum pump and is used to pick up the lens. The transfer platform 1131 can move and rotate along the Y-axis. The alignment component 1132 includes grippers disposed on both sides of the transfer platform 1131, and the two grippers can move synchronously towards or away from each other. The coordinate values ​​of the lens adsorbed on the transfer platform 1131 are acquired by the corner image acquisition device 1122.

[0100] The lens transfer mechanism 113 also includes a transfer transmission mechanism 1134 extending along the Y-axis. This transmission mechanism is connected to the transfer platform 1131 and the alignment component 1132 via a rotation mechanism 1133, which is movably connected to the transfer transmission mechanism 1134 along the Y-axis. The rotation mechanism 1133 drives the transfer platform 1131 and the alignment component 1132 to rotate around the Y-axis. Before fixing, the lens is first placed on the transfer platform 1131. After the lens is aligned by the alignment component 1132, the transfer platform 1131 is evacuated to absorb the lens. The transfer platform 1131 is rotated 90° around the Y-axis so that the lens faces the corner image acquisition device 1122. The image acquisition device is preferably a camera, with a supplementary light source placed next to the camera. The camera acquires the coordinate values ​​of the lens, preparing for the fixing component 1111 to accurately fix the lens.

[0101] Furthermore, such as Figure 9 As shown, the lens loading device 120 includes: a hopper, a tray, an output track, and an output position sensor. Multiple detection holes are spaced vertically on the side wall of the hopper. Multiple trays are spaced vertically within the hopper and can move vertically. The output track is arranged along the Y-axis, allowing the trays to be output from the hopper. The lowermost detection hole corresponds to the output track. The output position sensor is located on the side wall of the hopper at a position corresponding to the lowermost detection hole.

[0102] Preferably, the frame loading device 220 can adopt the same structure as the lens loading device 120. The only difference is that the tray of the lens loading device 120 is provided with multiple accommodating spaces suitable for accommodating lenses, while the tray of the frame loading device 220 is provided with multiple accommodating spaces suitable for accommodating frames.

[0103] Furthermore, an NG tray is provided on the output track for collecting waste products. The trays are spaced vertically within the hopper, and a transmission mechanism connected to the trays is located at the bottom of the hopper, allowing the trays to move vertically. The transmission mechanism can employ various existing technologies, such as screw-nut transmission mechanisms or rack and pinion transmission mechanisms, which will not be elaborated further. When the lowest tray moves to the lowest detection hole, the output position sensor detects that the tray has reached the output track position and outputs the tray along the output track so that it can be picked up and moved to the transfer station 1131.

[0104] Furthermore, the lens cleaning device is fixed to the base plate, and the lens cleaning device includes a lens cleaning nozzle arranged facing upwards.

[0105] Before installation, the lens must be cleaned to remove contaminants. Move the lens above the lens cleaning nozzle and spray it with plasma water for cleaning.

[0106] Furthermore, such as Figure 2 and Figure 12 As shown, the eyeglass frame cleaning device 250 includes an eyeglass frame blowing mechanism 251 and an eyeglass frame cleaning mechanism 252. The eyeglass frame blowing mechanism 251 is fixed to the base plate and includes an upward-facing blowing nozzle. The top of the blowing nozzle has an inclined surface, and an air hole communicating with an air storage container is provided on the inclined surface. The blowing nozzle can rotate around the Z-axis. The eyeglass frame cleaning mechanism 252 includes an eyeglass frame cleaning nozzle.

[0107] Before the frames are fixed, they also need to be cleaned to remove contaminants. Air is blown off the dust by the frame blowing mechanism 251. After the frames are fixed, plasma water is sprayed onto the mating surfaces of the frames through the frame cleaning nozzle.

[0108] The base is also equipped with a frame detection device 230. After the frame is cleaned of dust by the frame blowing mechanism, before the frame is fixed to the fixing shaft 211, in order to ensure accurate fixing, the frame is moved to the position of the frame detection device 230 to obtain the center coordinate position of the frame.

[0109] Furthermore, such as Figure 12 As shown, the transfer device 300 also includes a gantry 330, which includes two columns and is connected at the top of the two columns by a crossbeam extending along the X-axis. A transfer drive device is provided on the crossbeam and the transfer device is fixed on the transfer drive device, which is movable along the X-axis.

[0110] The gantry 330 spans the lens bonding device 100 and the frame fixing device 200 along the X-axis, facilitating various operations of the transfer device between the lens bonding device 100 and the frame fixing device 200.

[0111] Furthermore, the transfer device includes a first transfer assembly 310 and a second transfer assembly 320. The first transfer assembly 310 includes a first robotic arm and a lens manipulator 311. A lens Z-axis drive mechanism is provided on the first robotic arm, and the lens manipulator 311 is movably connected to the lens Z-axis drive mechanism along the Z-axis. A frame cleaning mechanism 252 is fixed to the first robotic arm. The second transfer assembly 320 includes a second robotic arm 321 and a frame manipulator. A frame Z-axis drive mechanism is provided on the second robotic arm 321, and the frame manipulator is movably connected to the frame Z-axis drive mechanism along the Z-axis. A dispensing device 240 is fixed to the second robotic arm 321.

[0112] The lens robot 311 primarily performs operations such as lens picking, cleaning, inspection, and installation. The frame robot primarily performs operations such as frame picking, cleaning, inspection, and installation. In addition, to facilitate other operations, corresponding devices are installed on the first and second robotic arms 321. For example, an adhesive dispensing device 240 is installed on the second robotic arm 321, and a frame cleaning device is installed on the first robotic arm.

[0113] Similar to the lens cleaning device, the frame cleaning unit is equipped with a frame cleaning nozzle, but the nozzle faces downwards. The frame cleaning unit is mounted on a frame robotic arm. After the frame measurement is completed, the first transfer assembly 310 drives the frame cleaning unit to move to the fixed shaft 211 directly above the frame, performing plasma cleaning on each bonding surface to improve its wettability. Then, the dispensing needle 241 dispenses a precise amount of adhesive according to the height of each bonding surface.

[0114] Furthermore, such as Figure 13 As shown, the eyeglass frame manipulator includes an eyeglass frame picking mechanism. The eyeglass frame picking mechanism is connected to the eyeglass frame Z-axis drive mechanism via a connecting bracket 323, which is connected to the eyeglass frame Z-axis drive mechanism at a 45° angle. The eyeglass frame picking mechanism includes an eyeglass frame suction head 322 and an eyeglass frame turntable 324. The eyeglass frame suction head 322 has two eyeglass frame adsorption surfaces at a 90° angle, and air holes communicating with a vacuum pump are provided on the two eyeglass frame adsorption surfaces. The two eyeglass frame adsorption surfaces are each at a 45° angle to the connecting bracket 323. The eyeglass frame turntable 324 fixes the eyeglass frame suction head 322 to the connecting bracket 323, and the eyeglass frame turntable 324 can rotate around the axis of the eyeglass frame suction head 322.

[0115] Based on the obtained coordinate position, the second transfer component 320 and the frame Z-axis drive mechanism work together to drive the frame to a designated position aligned with the fixed axis 211, in preparation for fixing the frame to the fixed axis 211.

[0116] The aforementioned frame manipulator ensures that one of the two frame suction surfaces of the frame suction head 322 is horizontal and the other is vertical. In use, the frame to be installed is picked up via the horizontal suction surface. After the second transfer assembly 320 moves to the frame fixing device 200, the lens that has been properly attached is picked up via the vertical suction surface. The frame suction head 322 is then rotated 90° via the frame turntable 324, bringing the frame to a vertical position and mounting it onto the fixed shaft 211.

[0117] A lens-mounted AA bonding method, comprising bonding a lens to a frame using a lens-mounted AA bonding assembly as described in any one of the above claims, wherein the bonding method includes:

[0120] Preferably, a lens detection and positioning camera is provided on the first transfer component 310. A lens robot 311 (preferably a lens suction head connected to a vacuum device, picking up lenses by vacuuming) is used. Before each lens is picked up, the lens detection and positioning camera first photographs the lens to be picked up in the tray, detecting the front and back of the lens and whether it is damaged (the chamfer dimensions of the front and back edges of the lens are different; the front and back of the lens are determined by the chamfer distance). If a lens is detected as reversed, it is skipped, and the next lens is detected. If a lens is detected as damaged, the lens robot 311 picks it up and places it in the NG tray, and the next lens is detected. After the lens detection and positioning camera has detected the lens, it obtains the coordinate position of the lens. The lens is adjusted to the position aligned with the lens robot 311 by the movement of the tray output track and the first transfer component 310. The lens robot 311 then descends to pick up the lens and sends it to the lens cleaning device for plasma cleaning to remove contaminants from the bottom surface of the lens and improve the wettability of the bottom surface, thereby improving the adhesion of the adhesive.

[0121] S120: The lens robot moves the lens onto the transfer platform, aligns and fixes the lens, rotates the transfer platform 90° so that the lens is set in a vertical direction, obtains the coordinate position of the lens through the corner camera, and moves the lens to the fixing part for fixation.

The frame is picked up by the frame robot and moved to the frame blowing mechanism to remove dust from the frame. The center coordinates of the frame are detected by the frame detection device and the frame robot is moved to the fixed axis position.

[0125] After the frame is cleaned, the second transfer component drives the frame to move directly above the lower camera. The frame detection device obtains the center coordinates of the frame. Based on the obtained coordinates, the second transfer component works in coordination to drive the frame to a designated position aligned with the fixed axis component.

[0126] S220. The lens is picked up from the fixed shaft by the vertically placed frame adsorption surface. The frame suction head rotates 90° so that the frame adsorption surface is vertical and the frame is installed on the fixed shaft.

Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
