Description

Technical Field

[0001] This invention belongs to the field of gripper technology, specifically relating to a high-precision gripper mechanism for optical lens barrel cap bonding machines. Background Technology

[0002] An optical lens barrel is a lens or lens group used in an optical system to focus light or form an image. It is widely used in various fields such as photography, videography, microscopy, telescopes, eyeglasses, and photolithography. An optical lens barrel generally consists of two parts: the optical lens barrel itself and the lens cap (CAP). During the production of an optical lens barrel, an assembly machine is used to assemble the optical lens barrel and the CAP.

[0003] The workflow of the CAP bonding machine is as follows: optical lens barrel clamping → CAP pre-tightening → CAP bonding → full length measurement. Specifically, the optical lens barrel is clamped and placed on the pre-tightening seat, and the CAP is clamped and placed on the optical lens barrel. After the pre-tightening seat rotates to pre-tighten the optical lens barrel and CAP, the pre-tightened optical lens barrel and CAP are transferred to the bonding seat. The bonding seat rotates to complete the bonding of the optical lens barrel and CAP, and finally the full length is measured.

[0004] During CAP pre-tightening, the optical lens barrel is placed on the rotating seat using high-precision grippers and fixed by the rotating seat. The CAP is then placed on the optical lens barrel using high-precision grippers. At this time, the rotating seat rotates clockwise 2-3 times and then counterclockwise 1-2 times. The pre-tightened CAP and optical lens barrel are then placed on the next rotating seat and connected by the connecting arm.

[0005] When the angle of the CAP deviates, the lower surface of the CAP will not be parallel to the upper surface of the optical lens barrel. When the CAP and the optical lens barrel are threaded together, the angular deviation will cause the threaded engagement of the CAP and the optical lens barrel to tilt. This will damage the pre-tightened threads of the CAP and the optical lens barrel, resulting in a reduced installation yield and production losses. If the threads of the CAP and the optical lens barrel are tilted, and tightening continues, the threaded engagement of the CAP and the optical lens barrel will generate a large force, causing damage to the CAP or the optical lens barrel. The resulting reaction force may also loosen the screws that fix the high-precision gripper, thus affecting the gripping accuracy of the high-precision gripper.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

The adjustment component determines the tilt angle of the optical lens barrel cap based on the parameters transmitted by the gravity sensing component. After the contact surfaces of the clamping plate and the stabilizing plate separate, the position of the stabilizing plate can be adjusted by the adjustment component to achieve fine adjustment of the position of the optical lens barrel cap.

[0010] In one or more embodiments of the present invention, a plurality of ball bearings are provided on the inner wall of the spherical groove, which makes the ball rotate more smoothly; a cooling groove is provided at the upper end of the mounting part, and a flow passage for dissipating heat from the motor is provided at the lower end of the cooling groove; the cooling groove and the flow passage are filled with lubricating fluid; a liquid distribution passage is connected between the flow passage and the ball bearings, and the liquid distribution passage is used to deliver lubricating fluid to the ball bearings when they rotate.

[0011] In one or more embodiments of the present invention, the clamping plate is provided with a fixing hole, the electric telescopic rod is disposed in the fixing hole, and the outer diameter of the electric telescopic rod is smaller than the outer diameter of the fixing hole; the stabilizing plate is provided with a locking structure that matches the electric telescopic rod, and the stabilizing plate and the electric telescopic rod are easily disassembled and assembled by the locking structure.

[0012] In one or more embodiments of the present invention, a tapered protrusion is provided on one end face of the stabilizing plate near the fixing hole, a section of the tapered protrusion is engaged with the fixing hole, and the outer wall of the tapered protrusion is in close contact with the inner wall of the fixing hole.

[0013] In one or more embodiments of the present invention, the side of the stabilizing plate with the telescopic rod is on the same horizontal plane as the side of the clamping piece with the groove. In the initial state, the anti-slip part protrudes from the side of the stabilizing plate with the telescopic rod, and the outer diameter of the telescopic rod is not greater than the outer diameter of the blind hole.

[0014] In one or more embodiments of the present invention, a mounting frame is vertically arranged on the main body of the bonding machine, and a mounting assembly is slidably connected to the mounting frame in the vertical direction. The mounting assembly is provided with a detection component for detecting the position of the optical lens barrel cover and the optical lens barrel.

[0015] In one or more embodiments of the present invention, the detection component includes a first detector, a second detector, and a second mounting plate. The first detector and the second detector are both horizontally slidably connected to the second mounting plate. The second detector is located above the first detector.

Compared with the prior art, the high-precision gripper mechanism for the optical lens barrel cap bonding machine of the present invention, by setting a clamping plate and a stabilizing plate, and setting an adjustment component that can adjust the stabilizing plate, ensures that the CAP and the optical lens barrel are always horizontal, avoiding the threads of the CAP and the optical lens barrel not being able to fit properly during the pre-tightening process, which would affect the pre-tightening efficiency of the CAP and the optical lens barrel. By setting a telescopic rod, an anti-slip part and an elastic structure, more stable clamping of the CAP and the optical lens barrel can be achieved. That is, it can avoid the situation where the CAP or the optical lens barrel is tilted during the fitting of the CAP and the optical lens barrel, which would lead to poor thread fit, thereby avoiding a reduction in production yield. It also avoids the reaction force generated when the CAP and the optical lens barrel are tightened due to thread misfit acting on the high-precision gripper, and minimizes the possibility of the screws fixing the high-precision gripper loosening, thus avoiding affecting the gripping accuracy of the high-precision gripper.

[0020] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0021] like Figure 1As shown, in one embodiment of the present invention, a high-precision gripper mechanism is used in an optical lens barrel cap bonding machine. The optical lens barrel cap bonding machine includes a bonding machine body 1, on which a first slide rail 101 is provided. A gripper drive mechanism 3 is laterally slidably connected to the first slide rail 101, and the high-precision gripper mechanism is installed at the lower end of the gripper drive mechanism 3. The gripper drive mechanism 3 can change the position of the high-precision gripper mechanism. A rotating seat 2 is installed on the bonding machine body 1. The high-precision gripper mechanism grips the CAP and then places it on the rotating seat 2. By rotating the rotating seat 2, the CAP can be threadedly connected to the optical lens barrel. By rotating in both directions, the thread fit between the CAP and the optical lens barrel can be detected.

[0022] like Figures 1-3 As shown, the gripper drive mechanism 3 includes a second slide rail 301 and a third slide rail 302 that can slide vertically on the second slide rail 301. A first mounting base 303 is vertically slidably connected to the third slide rail 302. Two second mounting bases 304 are gripped on the first mounting base 303. The second mounting bases 304 are used to drive at least two gripper bodies 4 to clamp the CAP or optical lens barrel. That is, one second mounting base 304 is used to clamp the CAP, and the other second mounting base 304 is used to clamp the optical lens barrel. The driving amplitude of the second slide rail 301, the third slide rail 302, and the first mounting base 303 gradually decreases, thereby achieving higher precision movement and enabling the CAP to make better contact with the optical lens barrel.

[0023] like Figures 3-7 As shown, the gripper body 4 includes gripping pieces 401 for gripping the optical lens barrel cap and the optical lens barrel. Grooves 4012 are formed on the gripping surfaces of multiple gripping pieces 401. A stabilizing plate 402 matching the groove 4012 is provided on the gripping piece 401. The optical lens barrel cap and the optical lens barrel are gripped by the stabilizing plate 402. The gripping pieces 401 and the stabilizing plate 402 are matched, and the stabilizing plate 402 can be separated from the gripping pieces 401. After the stabilizing plate 402 is separated from the gripping pieces 401, its position can be adjusted by an adjustment component. By adjusting the position of the stabilizing plate 402, the position of the CAP or the optical lens barrel can be adjusted, ensuring that the position of the optical lens barrel does not shift when it contacts the rotating seat 2 or when the CAP contacts the optical lens barrel. This prevents the threaded engagement between the CAP and the optical lens barrel from failing due to misalignment. This means that pre-tightening failure can be avoided due to CAP or optical lens barrel misalignment, thereby preventing the failure of pre-tightening from affecting the bonding of CAP and optical lens barrel and reducing production efficiency.

[0024] Specifically, the adjustment assembly includes a mounting part 8, which is mounted on the outer surface of the clamping plate 401 by a first bolt 5, thus fixing the clamping plate 401 and the mounting part 8. A spherical groove 801 is provided inside the mounting part 8, and a sphere 16 is rotatably connected within the spherical groove 801. Drive wheels 10 are provided in both the horizontal and vertical directions of the sphere 16. The rotation of the drive wheels 10 drives the sphere 16 to rotate, and the drive wheels 10 are driven by a motor 11. An electric telescopic rod 7 is provided between the sphere 16 and the stabilizing plate 402. When the sphere 16 rotates, the position of the electric telescopic rod 7 changes, causing the stabilizing plate 402 to move, thereby changing the position of the CAP or optical lens barrel, ensuring that the CAP or optical lens barrel is horizontal, facilitating the pre-tightening and connection of the CAP and optical lens barrel.

[0025] like Figures 3-4 As shown, the clamping plate 401 has a fixing hole 4011 for the electric telescopic rod 7 to pass through. The outer diameter of the fixing hole 4011 is much larger than the outer diameter of the electric telescopic rod 7, so that the electric telescopic rod 7 can swing at a certain angle within the fixing hole 4011 to adjust the position of the stabilizing plate 402.

[0026] like Figures 3-4 As shown, multiple balls 9 are rotatably connected to the inner wall of the spherical groove 801 to make the ball 16 slide, so that the ball 16 reduces friction with the spherical groove 801 during rotation and improves the service life of the adjustment component.

[0027] like Figure 6 As shown, a cooling groove 803 is provided on the upper surface of the mounting part 8. The cooling groove 803 is filled with lubricating fluid 12. The lower end of the cooling groove 803 is connected to a flow passage 802. The flow passage 802 is arranged along the direction in which the motor 11 is set. The lubricating fluid 12 can enter the flow passage 802 to dissipate heat from the motor 11, thereby improving the service life of the motor 11.

[0028] like Figure 7As shown, a liquid distribution passage 804 is provided between the flow passage 802 and the ball bearing 9. The ball bearing 9 can block one end of the liquid distribution passage 804. Due to the gravity of the lubricating fluid 12, the lubricating fluid 12 can always be located at the outlet end of the liquid distribution passage 804. When the ball bearing 9 rotates, the lubricating fluid 12 can adhere to the surface of the ball bearing 9 to reduce the friction between the ball bearing 9 and the mounting part 8 during rotation, thus reducing the resistance during the rotation of the ball bearing 9. At the same time, the outer surface of the ball bearing 9 with the lubricating fluid 12 can contact the mounting part 8, and the lubricating fluid 12 can adhere to the outer wall of the mounting part 8 through the ball bearing 9, reducing the resistance during the rotation of the mounting part 8. The lubricating fluid 12 can also reduce the heat output of the motor 11, the ball bearing 9, and the mounting part 8, and at the same time reduce the friction between the ball bearing 9 and the mounting part 8 during transportation, thereby improving the service life of the adjustment component.

[0029] like Figures 1-5 As shown, to improve the stability of the stabilizing plate 402 during the gripping process of the CAP or optical lens barrel, multiple evenly distributed blind holes 4021 are provided on the gripping surface of the stabilizing plate 402. A telescopic rod 403 is fixedly connected to the bottom wall of the blind hole 4021. One end of the telescopic rod 403 is fixedly connected to an anti-slip part 404, which contacts the CAP and the optical lens barrel. An elastic structure 405 is provided on the outside of the telescopic rod 403, which ensures that the initial state of the telescopic rod 403 is the extended state.

[0030] Specifically, the elastic structure 405 is an air bladder or spring, capable of restoring the telescopic rod 403 to its original shape. When the anti-slip part 404 contacts the CAP or optical lens barrel, the telescopic rod 403 shortens, and the elastic structure 405 generates deformation energy in the opposite direction, achieving a more stable clamping of the CAP or optical lens barrel. The outer diameter of the telescopic rod 403 is no larger than the outer diameter of the blind hole 4021, the telescopic rod 403 is located inside the blind hole 4021, and the surface of the telescopic rod 403 is on the same horizontal plane as the clamping surface of the stabilizing plate 402.

[0031] A gravity sensing component is installed between the outer cylinder and the inner rod of the telescopic rod 403. The gravity sensing component can also be installed at the bottom of the telescopic rod 403. The gravity sensing component can transmit parameters to the adjustment component. The adjustment component determines whether the CAP or optical lens barrel has shifted according to the transmitted parameters, and adjusts the position of the CAP or optical lens barrel according to the parameters.

[0032] Preferably, the parameters can be transmitted through the Internet of Things unit, and the transmitted parameters can be analyzed by the analysis unit. The analysis unit provides an adjustment plan and transmits the adjustment plan to the motor 11. The two motors 11 adjust the position of the CAP or optical lens barrel according to the adjustment plan.

[0033] like Figures 3-4As shown, a locking structure 6 is fixedly connected to one end of the stabilizing plate 402, and the stabilizing plate 402 is fixed to the electric telescopic rod 7 through the locking structure 6. The locking structure 6 can be a threaded locking structure, or a magnet or other structure that can fix the stabilizing plate 402 and the electric telescopic rod 7. It should also facilitate the disassembly of the stabilizing plate 402 and the electric telescopic rod 7. That is, when the clamping piece 401 needs to be replaced, the stabilizing plate 402 and the mounting part 8 can be disassembled and installed on the new clamping piece 401, which greatly reduces the cost of using the gripper body 4.

[0034] like Figures 3-4 As shown, after the clamping plate 401 and the stabilizing plate 402 are separated by the electric telescopic rod 7, the electric telescopic rod 7 can drive the stabilizing plate 402. A tapered protrusion 4022 is provided on one end face of the stabilizing plate 402 near the fixing hole 4011. One section of the tapered protrusion 4022 engages with the fixing hole 4011, and the outer wall of the tapered protrusion 4022 is in close contact with the inner wall of the fixing hole 4011. That is, when the tapered protrusion 4022 contacts the fixing hole 4011, the clamping plate 401 and the stabilizing plate 402 can be engaged, ensuring the stability of the stabilizing plate 402 within the clamping plate 401.

[0035] like Figure 1 , Figures 8-13 As shown, a mounting frame 13 is vertically mounted on the main body 1 of the bonding machine. The mounting frame 13 is located on the running path of the gripper body 4. A mounting assembly 14 is slidably connected vertically to the mounting frame 13. The mounting assembly 14 is equipped with a detection assembly 15 for detecting the position of the optical lens barrel cap and the optical lens barrel. That is, during the process of gripping the optical lens barrel and CAP, the gripper body 4 can detect the position of the optical lens barrel and CAP, and simultaneously adjust the position of the optical lens barrel and CAP in conjunction with the adjustment assembly. In other words, the detection assembly 15 can achieve secondary detection of the position of the optical lens barrel and CAP, thereby ensuring that the positions of CAP and the optical lens barrel do not shift.

[0036] Specifically, the detection component 15 includes a first detector 1501, a second detector 1502, and a second mounting plate 1503. The first detector 1501 and the second detector 1502 are both horizontally slidably connected to the second mounting plate 1503. The second detector 1502 is located at the upper end of the first detector 1501. The second detector 1502 and the first detector 1501 form a detection plane profile that matches the optical lens barrel cover and the optical lens barrel.

[0037] like Figures 8-9As shown, the second mounting plate 1503 has a second sliding groove 15031 and a third sliding groove 15032. The second detector 1502 is slidably connected in the second sliding groove 15031, and the two first detectors 1501 are slidably connected in the third sliding groove 15032. By sliding the second detector 1502 and the first detector 1501, the size of the detection profile of the detection component 15 can be changed, thereby realizing the detection of CAP or optical lens barrels of different specifications.

[0038] The mounting frame 13 has a first sliding groove 1301 and a first through hole 1302. The mounting assembly 14 includes a first mounting plate 1401, which is slidably connected to the mounting frame 13 via the first sliding groove 1301 and the first through hole 1302. One end of the mounting assembly 14 is fixedly connected to a sliding rod 1403 that matches the first through hole 1302. A fixing plate 1402 is slidably connected to the sliding rod 1403. A spring 1404 is sleeved on the sliding rod 1403, and both ends of the spring 1404 are fixed to the first mounting plate 1401 and the fixing plate 1402, respectively. The sliding rod 1403 is slidably connected in the first through hole 1302, meaning that the spring 1404 increases the friction between the first mounting plate 1401 and the fixing plate 1402 and the mounting frame 13, thereby allowing the mounting assembly 14 to slide to any position and stop, preventing it from sliding randomly.

[0039] like Figure 10 As shown, the slide rod 1403 has a threaded hole 14031, and the fixing plate 1402 has a second through hole 14021. The second through hole 14021 passes through the slide rod 1403, and a second bolt 1405 is installed in the second through hole 14021. The second bolt 1405 passes through the second through hole 14021 and is threadedly connected to the threaded hole 14031. The second bolt 1405 can completely lock the first mounting plate 1401 and the fixing plate 1402 onto the mounting bracket 13, thereby ensuring that the mounting assembly 14 will not shake during use and is convenient for long-term use.

[0040] In use, the gripper drive mechanism 3 first slides to the lower end of the optical lens barrel, driving the gripper body 4 to clamp the optical lens barrel onto the rotating base 2. The gripper drive mechanism 3 then slides to the upper end of the CAP (Optical Lens Cap), again driving the gripper body 4 to clamp the CAP and place it on the upper end of the optical lens barrel. This causes the rotating base 2 to rotate the optical lens barrel, resulting in a threaded engagement between the CAP and the optical lens barrel, achieving pre-tightening. When the gripper body 4 clamps the optical lens barrel or CAP, the optical lens barrel or CAP comes into contact with the anti-slip part 404. The gripping action of the gripper body 4 causes the telescopic rod 403 to deform to match the shape of the optical lens barrel or CAP, achieving better clamping of the optical lens barrel or CAP through the telescopic rod 403 and the anti-slip part 404. The telescopic rod 403 applies pressure to the gravity sensing component. If the optical lens barrel or CAP is clamped parallel to the horizontal plane, since the optical lens barrel and CAP are generally circular, the gravity sensing modules mounted on different stabilizing plates 402 will experience the same force. If the gravity sensing modules on different stabilizing plates 402 experience different forces, it can be determined that the optical lens barrel or CAP is not parallel to the horizontal plane. This parameter is transmitted to the adjustment component, which adjusts the position of the optical lens barrel or CAP to ensure that the optical lens barrel or CAP is horizontal to the horizontal plane.

[0041] When the adjustment assembly is in use, it first pushes the stabilizing plate 402 away from the clamping piece 401 via the electric telescopic rod 7, causing the clamping piece 401 and the stabilizing plate 402 to separate by a certain distance. Then, the ball 16 is rotated by the vertical drive wheel 10. After the vertical position is changed, the ball 16 is rotated by the horizontal drive wheel 10, causing the ball 16 to rotate, which in turn rotates the electric telescopic rod 7. The electric telescopic rod 7 changes the position of the stabilizing plate 402 to ensure that the CAP or optical lens barrel is horizontal, preventing the CAP or optical lens barrel from tilting and causing the threaded fit of the CAP and optical lens barrel to fail. This avoids unsuccessful pre-tightening of the CAP and optical lens barrel, which would affect the production yield. The detection assembly 15 performs secondary detection of the optical lens barrel and CAP after the adjustment assembly is completed.

[0042] Furthermore, when the clamping plate 401 malfunctions, the optical lens barrel and CAP can still be clamped simply by driving the stabilizing plate 402 to its position via the electric telescopic rod 7. This provides compensation for damage to the clamping plate 401.

[0043] This invention, by setting a clamping piece 401 and a stabilizing plate 402, and providing an adjustment component capable of adjusting the stabilizing plate 402, ensures that the CAP and the optical lens barrel are always horizontal, preventing the threads of the CAP and the optical lens barrel from failing to mesh during pre-tightening, thus affecting the pre-tightening efficiency. The invention also achieves more stable clamping of the CAP and the optical lens barrel by setting a telescopic rod 403, an anti-slip part 404, and an elastic structure 405. A detection component 15 is installed during the operation of the gripper drive mechanism 3 to perform secondary detection on the CAP and the optical lens barrel on the gripper drive mechanism 3, ensuring that the CAP or the optical lens barrel is horizontal after adjustment by the adjustment component. In the event that the clamping piece 401 cannot function properly, the electric telescopic rod 7 drives the stabilizing plate 402, ensuring that the stabilizing plate 402 can clamp the CAP or the optical lens barrel, thus compensating for the damage to the clamping piece 401.
