[0002] In the production process of camera products, the focus of the lens module needs to be adjusted after assembly to ensure the clarity of the image captured by the lens module. In the past, most lens modules had petals, and the focusing claws could be inserted into the gaps between the petals to adjust the focus. However, for lens modules without petals, such focusing devices are not suitable. Traditional manual focusing is usually used. After connecting the lens module to the computer, the lens module is manually rotated, and the computer screen displays the effect of the lens module in real time. The operator judges the focus by observing the clarity of the image, and finally the program captures the image to judge the result.

The support plate 6 includes a first rotating disk 3A, three equally circumferentially arranged centering gripper devices 3B for clamping the lens module 10, an opening ring device 3C located below the first rotating disk 3A for opening the centering gripper devices 3B, a lens device 3D located above the first rotating disk 3A for focusing the lens module 10, and a first driving device 3E for driving the first rotating disk 3A to rotate the centering gripper devices 3B to focus the lens module 10. The lens module 10 is assembled by distributing three directions around the switching mechanism 2 to the focusing mechanism 3, the dispensing mechanism 4, and the UV curing mechanism 5, with the remaining direction designated as the loading and unloading station. Three equally spaced centering grippers 3B are positioned in the focusing mechanism 3 to clamp the focusing ring in the lens module 10. The first drive device 3E drives the first rotating disk 3A to rotate, causing the centering grippers 3B to rotate around the lens module 10, thus achieving focusing of the lens module 10. An opening ring device 3C located below the first rotating disk 3A pushes the three centering grippers 3B outward to loosen the lens module 10. The switching mechanism 2 then moves the focused lens module 10 sequentially to the dispensing mechanism 4 and the UV curing mechanism 5 to fix the lens module 10.

[0030] The centering gripper device 3B includes a second support plate 3B1 mounted on the first rotating disk 3A and arranged radially, a gripper arm 3B2 slidably disposed on the second support plate 3B1 and used to press and clamp the lens module 10, a gripper opening cam 3B3 disposed at the lower end of the gripper arm 3B2 and used to contact the opening ring device 3C and be pushed away to release the lens module 10, and a first clamping spring 3B4 disposed at the rear end of the gripper arm 3B2 and used to push the gripper arm 3B2 to maintain the clamping tendency of the lens module 10.

[0031] The first rotating disk 3A is also equipped with a triangular positioning plate assembly 3F for centering the lens module 10, and the first support plate 6 is also provided with a gripper elasticity adjustment device 3G and an adjustment pressure monitoring device 3H located next to the first rotating disk 3A for adjusting the clamping force of the centering gripper device 3B.

The triangular positioning plate assembly 3F includes a triangular star plate 3F1 mounted on the first rotating disk 3A and a positioning sleeve 3F2 located at the center of the triangular star plate 3F1 for positioning the lens module 10. The gripper spring force adjustment device 3G includes a first push cylinder 3G1 radially disposed on the side of the first rotating disk 3A, a first motor 3G2 disposed on the first push cylinder 3G1 for driving the spring force adjustment screw 3B8 to rotate, a bit 3G3 disposed on the output shaft of the first motor 3G2 and capable of engaging with the spring force adjustment screw 3B8, and a coupling 3G4 for connecting the first motor 3G2 and the bit 3G3. The front end of the coupling 3G4 is provided with a floating mounting bracket. A connecting sleeve 3G5 is provided for mounting the bit 3G3. A first floating spring 3G6 is provided inside the connecting sleeve 3G5 to press against the rear end of the bit 3G3. The rear end of the bit 3G3 is mounted on the connecting sleeve 3G5 through a connecting pin 3G7. The connecting sleeve 3G5 is provided with a strip-shaped through hole 3G51 for the connecting pin 3G7 to pass through and move. A first retaining ring 3G8 and a second retaining ring 3G9 are installed at both ends of the connecting pin 3G7 to press against the outside of the strip-shaped through hole 3G51.

[0034] The first rotating disk 3A is also provided with three circumferentially distributed first detection probe female seats 3I, which correspond one-to-one with the three centering gripper devices 3B. The first detection probe female seats 3I and the centering gripper devices 3B are alternately distributed on the first rotating disk 3A. When each centering gripper device 3B is adjusting the pressure by docking with the gripper elasticity adjustment device 3G, the corresponding first detection probe female seat 3I can make contact with the adjustment pressure monitoring device 3H. The adjustment pressure monitoring device 3H includes a second push cylinder 3H1 arranged radially on the side of the first rotating disk 3A and a first detection probe male seat 3H2 installed on the second push cylinder 3H1 and capable of making corresponding contact with the first detection probe female seat 3I.

[0035] The gripper arm 3B2 has a first support guide rod 3B9 and a second support guide rod 3B10 slidably mounted on both sides to support the first clamping spring 3B4. A first pressure plate 3B11 is installed at the other end of the first support guide rod 3B9 and the second support guide rod 3B10 and located in front of the movable pressure adjusting plate 3B7. A pressure sensor 3B12 is provided between the first pressure plate 3B11 and the movable pressure adjusting plate 3B7 to detect the contact pressure between the gripper arm 3B2 and the lens module 10. The first clamping spring 3B4 includes two springs respectively mounted on the first support guide rod 3B9 and the second support guide rod 3B10. The front end of the second support plate 3B1 is formed with a first limiting protrusion 3B14 extending to one side and used to limit the movement of the gripper arm 3B2. The rear end of the gripper arm 3B2 is formed with a second limiting protrusion 3B15 extending upward to the rear end of the first limiting protrusion 3B14. The second limiting protrusion 3B15 is provided with a second buffer 3B16 for contacting and buffering with the first limiting protrusion 3B14.

[0036] A pulley assembly 3J is provided between the first driving device 3E and the first rotating disk 3A for transmission. The pulley assembly 3J is located at the lower end of the first support plate 6. A first tension adjusting wheel 3K and a second tension adjusting wheel 3L are movably provided on both sides of the first driving device 3E to open the pulley assembly 3J and adjust the tension. The opening ring device 3C includes a push sleeve 3C1 located below the first rotating disk 3A and capable of being inserted into the first rotating disk 3A to push the gripper opening cam 3B3, and a third push cylinder 3C2 and a fourth push cylinder 3C3 installed on both sides of the first support plate 6 to push the push sleeve 3C1 to open the gripper opening cam 3B3. One end of the push sleeve 3C1 is conical and contacts and presses against the gripper opening cam 3B3 to push the gripper opening cam 3B3 to expand towards the outer diameter of the first rotating disk 3A. In this invention, the three centering gripper devices 3B maintain a clamping force relative to each other at the center through the reset force of the first clamping spring 3B4. When it is necessary to position the lens module 10, the third push cylinder 3C2 and the fourth push cylinder 3C3 simultaneously drive the push sleeve 3C1 to insert into the first rotating disk 3A and contact and press against the gripper opening cam 3B3. The push sleeve cam 3B3 drives the gripper arm 3B2 to move outward, compressing the first clamping spring 3B4. This forms a clamping space at the center of the docking of the three centering gripper devices 3B. After the lens module 10 is inserted into the clamping space between the three centering gripper devices 3B, the third push cylinder 3C2 and the fourth push cylinder 3C3 simultaneously drive the push sleeve 3C1 to push out of the first rotating disk 3A. This causes the first clamping spring 3B4 in the three centering gripper devices 3B, which has lost its clamping force, to push the gripper arm 3B2 to release the lens module 10. Similarly, when the lens module 10 is released, the opening ring device 3C performs the same action to push the three centering gripper devices 3B to expand outward and release the lens module 10, thereby achieving the clamping and releasing of the lens module 10.

[0037] The focusing mechanism 3 further includes a first X-axis motion module 31 disposed beside the shifting mechanism 2, a first Y-axis motion module 32 disposed on the first X-axis motion module 31, and a first Z-axis motion module 33 disposed on the first Y-axis motion module 32 for driving the first support plate 6 to move. A first support plate 313 is vertically disposed at the rear end of the first support plate 6 and mounted on a first Z-axis guide rail 311 and a second Z-axis guide rail 312. A third Z-axis guide rail 314 and a fourth Z-axis guide rail 315 are disposed on both sides of the first support plate 313 for supporting the movement of the lens device 3D. A first adjusting screw 316 is disposed at the upper end of the first support plate 313 for adjusting the distance between the lens device 3D and the first support plate 6. The distance between the lens device 3D and the lens module 10 is 9mm.

[0038] A camera 34 for visual positioning of the lens module 10 and a laser height measuring device 35 for accurately detecting the height of the first support plate 6 driven by the first Z-axis motion module 33 are provided on one side of the first support plate 6. The camera 34 takes pictures of the lens module 10 to determine its precise position, so that the first X-axis motion module 31, the first Y-axis motion module 32 and the first Z-axis motion module 33 can cooperate to move the first rotating disk 3A onto the lens module 10 and make the lens module 10 accurately pass into the positioning sleeve 3F2 of the triangular positioning plate assembly 3F to prevent the lens module 10 from colliding and being damaged with the triangular positioning plate assembly 3F. The laser height measuring device 35 monitors the height of the first support plate 6 in real time to prevent the lens module 10 from colliding and being damaged with the lens device 3D when passing through the triangular positioning plate assembly 3F.

[0039] Above the switching mechanism 2, a large light plate module 7 is also provided, and the switching mechanism 2 is a four-station switching mechanism. The focusing mechanism 3, the dispensing mechanism 4, and the UV curing mechanism 5 are arranged in sequence around the three stations of the switching mechanism 2, and the other station of the switching mechanism 2 is set as a manual loading and unloading station.

[0040] The switching mechanism 2 includes a hollow rotating platform 21, a second rotating disk 22 arranged in a cross shape on the hollow rotating platform 21, a mercury slip ring 23 arranged in the middle of the second rotating disk 22 for configuring air pipes and lines, four positioning fixtures 24 arranged at the corners of the second rotating disk 22 for positioning the lens module 10, and a PCBA adapter plate 25 arranged at the lower end of the positioning fixtures 24 for connecting the lens module 10 to transmit data. The focusing mechanism 3, the dispensing mechanism 4, and the manual loading and unloading station are all equipped with conductive connector devices 26 located below the second rotating disk 22 and capable of being lifted to contact and conduct with the PCBA adapter plate 25. A data cable 27 is provided between the lens module 10 and the PCBA adapter plate 25. Four positioning fixtures 24 for holding and clamping lens modules 10 are set on the second rotating disk 22. By evenly distributing the four positioning fixtures 24 around the second rotating disk 22, the hollow rotating platform 21 can drive the second rotating disk 22 to switch positions at equal angles each time. This allows the four positioning fixtures 24 on the second rotating disk 22 to switch sequentially between the manual loading and unloading position, the focusing mechanism 3, the dispensing mechanism 4, and the UV curing mechanism 5, and enables the four positions to work synchronously, thereby improving production efficiency.

[0041] The positioning fixture platform 24 includes a support fixture frame 241 disposed on the PCBA adapter plate 25 for supporting the lens module 10, and a fixture cover plate 242 hinged to the support fixture frame 241 for covering and fixing the lens module 10. The upper end face of the PCBA adapter plate 25 is provided with a plurality of connector interfaces 251 that match the data cable 27, and the lower end face of the PCBA adapter plate 25 is provided with a second detection probe female socket 252 for mating and docking with the conductive connector device 26. The conductive connector device 26 includes a fifth push cylinder 261. The system includes a second detection probe male seat 262 mounted on the fifth push cylinder 261 and used for mating and interlocking with the second detection probe female seat 252; a first positioning pin 263 and a second positioning pin 264 mounted on both sides of the second detection probe male seat 262 and used for docking and positioning at the bottom of the second rotating disk 22; and a first buffer 265 mounted on the fifth push cylinder 261 and used for contacting the bottom of the second rotating disk 22. The bottom of the second rotating disk 22 is provided with a first pin hole seat 221 and a second pin hole seat 222 corresponding to the first positioning pin 263 and the second positioning pin 264, respectively.

[0042] In summary, during operation, an employee installs the lens module 10 onto the positioning fixture 24 from the manual loading / unloading station, and connects the lens module 10 to the PCBA adapter board 25 via the data cable 27. The lens module 10 is then transferred to the focusing mechanism 3 via the switching mechanism 2. Further, the first X-axis motion module 31, the first Y-axis motion module 32, and the first Z-axis motion module 33 in the focusing mechanism 3 cooperate to mount the first rotating disk 3A onto the lens module 10 in the positioning fixture 24. During this process, the opening ring assembly... The device 3C pushes the three centering gripper devices 3B outwards, facilitating the insertion of the lens module 10 into the center of the three centering gripper devices 3B. Then, the opening ring device 3C releases the three centering gripper devices 3B to clamp the lens module 10. Further, the conductive connector device 26 below the focusing mechanism 3 contacts and connects with the PCBA adapter plate 25. The first drive device 3E drives the first rotating disk 3A to rotate via the pulley assembly 3J, causing the adjustment pressure monitoring device 3H and the gripper elasticity adjustment device 3G to sequentially engage with the first detection device of their respective groups. The probe socket 3I and the centering gripper device 3B are connected. The gripper spring force adjustment device 3G drives the spring force adjustment screw 3B8 to rotate based on data feedback from the pressure sensor 3B12. This adjusts the pressure of each centering gripper device 3B in contact with the lens module 10, ensuring accurate pressure measurement and preventing damage to the lens module 10. Furthermore, based on the automatic image analysis program performed by the lens device 3D in conjunction with the lens module 10, the adjustment angle is determined according to the calculated score, allowing for quick and accurate finding of the optimal focal length. The first drive device 3E drives the first rotating disk 3A to rotate via the pulley assembly 3J to complete the focusing of the lens module 10. Further, the switching mechanism 2 transfers the lens module 10 to the dispensing mechanism 4 for dispensing, then the switching mechanism 2 transfers the lens module 10 to the UV curing mechanism 5 for adhesive curing. Finally, the switching mechanism 2 transfers the lens module 10 to the manual loading / unloading station, where the operator removes the focused lens module 10 and replaces it with the lens module 10 to be focused, thus achieving continuous cyclic focusing of the lens module 10. This focusing equipment is mainly for lenses without petals. It uses a three-jaw chuck to grip the lens for focusing. Pressure sensors adjust the pressure of each jaw to ensure uniform force on the lens and maintain focusing stability. After focusing, the image is visually inspected, and adhesive is applied to cure the lens, ensuring the focal length remains constant. The three-jaw chuck automatically focuses the lens, and the program automatically analyzes the image, determining the adjustment angle based on the calculated score. This allows for quick and accurate finding of the optimal focal length, improving work speed and ensuring image quality.
