Description

Technical Field

[0001] The invention belongs to the technical field of clamping jaws, and in particular relates to a high-precision clamping jaw mechanism for an optical lens cover binding machine. Background Art

[0002] An optical lens barrel is a lens or lens group used in an optical system. Its function is to focus or form an image of light. It is widely used in various fields such as photography, videography, microscopes, telescopes, glasses, and photolithography. An optical lens barrel generally consists of an optical lens barrel and a lens cap (CAP). During the production process of an optical lens barrel, a bonding machine is required to assemble the optical lens barrel and the CAP.

[0003] The working process of the CAP binding machine is: optical lens barrel clamping → CAP pre-tightening → CAP binding → full length measurement. Specifically, the optical lens barrel is clamped and placed on the pre-tightening seat, the CAP is clamped and placed on the optical lens barrel, the pre-tightening seat rotates to pre-tighten the optical lens barrel and the CAP, and then the pre-tightened optical lens barrel and the CAP are transferred to the binding seat, the binding seat rotates to complete the binding of the optical lens barrel and the CAP, and finally the full length measurement is performed.

[0004] When the CAP is pre-tightened, the optical lens barrel is placed on the rotating seat by high-precision clamps and fixed by the rotating seat. The CAP is placed on the optical lens barrel by high-precision clamps. At this time, the rotating seat rotates clockwise for 2 to 3 turns, and then rotates counterclockwise for 1 to 2 turns at a certain angle. Then the pre-tightened CAP and optical lens barrel are placed on the next rotating seat and fastened by the fastening arm.

[0005] When the angle of the CAP is offset, the lower surface of the CAP will not be parallel to the upper surface of the optical lens barrel. When the threads of the CAP and the optical lens barrel are matched, the angle offset will cause the matching of the threads of the CAP and the optical lens barrel to tilt, which will cause damage to the threads of the pre-tightened CAP and the optical lens barrel, resulting in a decrease in the installation yield of the CAP and the optical lens barrel, causing losses to production. The threads of the CAP and the optical lens barrel are tilted. At this time, if you continue to twist, the thread matching of the CAP and the optical lens barrel will generate a large force, causing damage to the CAP or the optical lens barrel. The reaction force generated may also cause the screws that fix the high-precision clamp to loosen, thereby affecting the grasping accuracy of the high-precision clamp.

DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0037] like Figure 1As shown, a high-precision clamping mechanism is used for an optical lens cap binding machine in one embodiment of the present invention. The optical lens barrel cap binding machine comprises a binding machine body 1, on which a first slide rail 101 is provided. The first slide rail 101 is laterally slidably connected with a clamping driving mechanism 3, and the high-precision clamping mechanism is installed at the lower end of the clamping driving mechanism 3. The clamping driving mechanism 3 can change the position of the high-precision clamping mechanism. A rotating seat 2 is installed on the binding machine body 1, and the CAP is clamped by the high-precision clamping mechanism and then placed on the rotating seat 2. The rotating seat 2 is rotated so that the CAP can be threadedly connected with the optical lens barrel. The thread matching of the CAP and the optical lens barrel is detected by forward and reverse rotation.

[0038] like Figure 1 to Figure 3 As shown, the clamp driving mechanism 3 includes a second slide rail 301 and a third slide rail 302 that can slide vertically on the second slide rail 301, and a first mounting seat 303 is vertically slidably connected to the third slide rail 302. Two second mounting seats 304 are clamped on the first mounting seat 303, and the second mounting seats 304 are used to drive at least two clamping jaw bodies 4 to clamp the CAP or the optical lens barrel. That is, one of the second mounting seats 304 is used to clamp the CAP, and the other second mounting seat 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 seat 303 is gradually reduced, thereby achieving a higher precision movement, so that the CAP can be in better contact with the optical lens barrel.

[0039] like Figure 3 to Figure 7 As shown, the clamp body 4 includes a clamping piece 401, and the clamping piece 401 is used to grasp the optical lens barrel cover and the optical lens barrel. A groove 4012 is provided on the grasping surface of the plurality of clamping pieces 401, and a stabilizing plate 402 matching the groove 4012 is provided on the clamping piece 401. The optical lens barrel cover and the optical lens barrel are clamped by the stabilizing plate 402, and the clamping piece 401 matches the stabilizing plate 402. The stabilizing plate 402 can be separated from the clamping piece 401. When the stabilizing plate 402 and the clamping piece 401 are separated, the position of the stabilizing plate 402 can be adjusted by adjusting the assembly. By adjusting the position of the stabilizing plate 402, the position of the CAP or the optical lens barrel can be adjusted to ensure that when the optical lens barrel contacts the rotating seat 2 or the CAP contacts the optical lens barrel, its position will not be offset, so that the threaded fit between the CAP and the optical lens barrel will not fail to fit due to the offset of the CAP or the optical lens barrel. That is, it can avoid preload failure caused by deviation of CAP or optical lens barrel, thereby avoiding the situation where preload failure affects the connection between CAP and optical lens barrel and reduces production efficiency.

[0040] Specifically, the adjustment assembly includes a mounting portion 8, which is mounted on the outer surface of the clamping plate 401 by a first bolt 5 to fix the clamping plate 401 and the mounting portion 8. A spherical groove 801 is provided inside the mounting portion 8, and a sphere 16 is rotatably connected in the spherical groove 801. The sphere 16 is provided with driving wheels 10 in both the horizontal and vertical directions. The driving wheels 10 can drive the sphere 16 to rotate, and the driving 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 is changed, and the electric telescopic rod 7 moves with the stabilizing plate 402, thereby changing the position of the CAP or the optical lens barrel, so that the CAP or the optical lens barrel can be level with the horizontal plane, which is convenient for pre-tightening and binding of the CAP and the optical lens barrel.

[0041] like Figure 3-4 As shown, a fixing hole 4011 for the electric telescopic rod 7 to pass through is opened on the clamping piece 401, and 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 a certain angle in the fixing hole 4011 to adjust the position of the stabilizing plate 402.

[0042] like Figure 3-4 As shown, a plurality of balls 9 for sliding the ball 16 are rotatably connected to the inner wall of the spherical groove 801, so that the friction between the ball 16 and the spherical groove 801 is reduced during the rotation process, thereby improving the service life of the adjustment component.

[0043] like Figure 6 As shown, a cooling groove 803 is opened on the upper end surface of the mounting portion 8, and the cooling groove 803 is filled with a lubricating liquid 12. The lower end of the cooling groove 803 is connected to a flow passage 802, and the flow passage 802 is arranged along the direction in which the motor 11 is arranged. The lubricating liquid 12 can enter the flow passage 802, and can dissipate the heat of the motor 11, thereby improving the service life of the motor 11.

[0044] like Figure 7As shown, a liquid separation passage 804 is provided between the flow passage 802 and the ball 9, and the ball 9 can block one end of the liquid separation passage 804. Due to the gravity of the lubricating liquid 12, the lubricating liquid 12 can be ensured to be always located at the outlet end of the liquid separation passage 804. When the ball 9 rotates, the lubricating liquid 12 can adhere to the surface of the ball 9 to reduce the friction between the ball 9 and the mounting portion 8 during the rotation process, and reduce the resistance during the rotation process of the ball 9. At the same time, the outer surface of the ball 9 with the lubricating liquid 12 attached can contact the mounting portion 8, and the lubricating liquid 12 can adhere to the outer wall of the mounting portion 8 through the ball 9, reducing the resistance during the rotation process of the mounting portion 8. The lubricating liquid 12 can also reduce the heat output by the motor 11, the ball 9 and the mounting portion 8, and at the same time, reduce the friction between the ball 9 and the mounting portion 8 during transportation, thereby improving the service life of the adjustment component.

[0045] like Figure 1 to Figure 5 As shown, in order to improve the stability of the stabilizing plate 402 in the process of grabbing the CAP or the optical lens barrel, a plurality of evenly distributed blind holes 4021 are provided on the grabbing surface of the stabilizing plate 402, and a telescopic rod 403 is fixedly connected to the bottom wall of the blind hole 4021, and an anti-slip portion 404 is fixedly connected to one end of the telescopic rod 403, and the anti-slip portion 404 contacts the CAP and the optical lens barrel. An elastic structure 405 is provided on the outside of the telescopic rod 403, and the initial state of the telescopic rod 403 is an extended state through the elastic structure 405.

[0046] Specifically, the elastic structure 405 is an air bag or a spring, which can restore the telescopic rod 403 to its original shape. When the anti-slip portion 404 contacts the CAP or the optical lens barrel, the length of the telescopic rod 403 is shortened, and the elastic structure 405 generates deformation energy in the opposite direction, thereby achieving a more stable clamping of the CAP or the optical lens barrel. The outer diameter of the telescopic rod 403 is not greater than the outer diameter of the blind hole 4021, and 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.

[0047] A gravity sensing component is provided between the outer tube and the inner rod of the telescopic rod 403, and the gravity sensing component can also be provided at the bottom of the telescopic rod 403. The gravity sensing component can transmit parameters to the adjustment component through the gravity sensing component. The adjustment component determines whether the CAP or the optical lens barrel is offset according to the transmitted parameters, and adjusts the position of the CAP or the optical lens barrel according to the parameters.

[0048] Preferably, the parameters can be transmitted through the Internet of Things unit, and the transmitted parameters are 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 respectively adjust the position of the CAP or the optical lens barrel according to the adjustment plan.

[0049] like Figure 3-4As shown, one end of the stabilizing plate 402 is fixedly connected with a locking structure 6, and the stabilizing plate 402 is fixed by the locking structure 6 and the electric telescopic rod 7. 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, and it should also be easy to disassemble 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 portion 8 can be disassembled, and the stabilizing plate 402 and the mounting portion 8 can be installed on a new clamping piece 401, which greatly reduces the cost of the clamping jaw body 4 when in use.

[0050] like Figure 3-4 As shown, after the clamping piece 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 conical convex portion 4022 is provided on one end surface of the stabilizing plate 402 close to the fixing hole 4011, a section of the conical convex portion 4022 matches with the fixing hole 4011, and the outer side wall of the conical convex portion 4022 is in close contact with the inner wall of the fixing hole 4011. That is, when the conical convex portion 4022 contacts with the fixing hole 4011, the clamping piece 401 and the stabilizing plate 402 can be clamped, thereby ensuring the stability of the stabilizing plate 402 in the clamping piece 401.

[0051] like Figure 1 , Figure 8 to Figure 13 As shown, a mounting frame 13 is vertically arranged on the binding machine body 1, and the mounting frame 13 is located on the running path of the clamp body 4. A mounting assembly 14 is vertically slidably connected to the mounting frame 13, and a detection assembly 15 for detecting the position of the optical lens barrel cover and the optical lens barrel is arranged on the mounting assembly 14. That is, the clamp body 4 can detect the position of the optical lens barrel and the CAP in the process of clamping the optical lens barrel and the CAP, and at the same time cooperate with the adjustment assembly to adjust the position of the optical lens barrel and the CAP. That is, the detection assembly 15 can realize the secondary detection of the position of the optical lens barrel and the CAP, thereby ensuring that the position of the CAP and the optical lens barrel will not be offset.

[0052] Specifically, the detection assembly 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 contour that matches the optical lens barrel cover and the optical lens barrel.

[0053] like Figure 8-Figure 9As shown, a second sliding groove 15031 and a third sliding groove 15032 are provided on the second mounting plate 1503, 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.

[0054] The mounting frame 13 is provided with a first slide groove 1301 and a first through hole 1302, the mounting assembly 14 comprises a first mounting plate 1401, the first mounting plate 1401 is slidably connected to the mounting frame 13 through the first slide groove 1301 and the first through hole 1302, one end of the mounting assembly 14 is fixedly connected with a slide bar 1403 matching the first through hole 1302, the slide bar 1403 is slidably connected with a fixing plate 1402, the slide bar 1403 is sleeved with a spring 1404, and the two ends of the spring 1404 are respectively fixed to the first mounting plate 1401 and the fixing plate 1402. The slide bar 1403 is slidably connected in the first through hole 1302, that is, the spring 1404 can increase the friction between the first mounting plate 1401 and the fixing plate 1402 and the mounting frame 13, so that the mounting assembly 14 can slide to any position, can stay, and will not slide randomly.

[0055] like Fig.10 As shown, a threaded hole 14031 is provided on the slide bar 1403, and a second through hole 14021 is provided on the fixing plate 1402. The second through hole 14021 passes through the slide bar 1403, and a second bolt 1405 is provided 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 first mounting plate 1401 and the fixing plate 1402 can be completely locked on the mounting frame 13 by the second bolt 1405, thereby ensuring that the mounting assembly 14 will not shake during use, and is convenient for long-term use.

[0056] When in use, first slide to the lower end of the optical lens barrel through the clamp driving mechanism 3, the clamp driving mechanism 3 drives the clamp body 4 to clamp the optical lens barrel, and clamp the optical lens barrel to the rotating seat 2, and then the clamp driving mechanism 3 slides to the upper end of the CAP, the clamp driving mechanism 3 drives the clamp body 4 to clamp the CAP, and place the CAP on the upper end of the optical lens barrel, and make the rotating seat 2 rotate the optical lens barrel, so that the CAP and the optical lens barrel threads match to achieve pre-tightening. When the clamp body 4 clamps the optical lens barrel or CAP, the optical lens barrel or CAP will contact the anti-slip part 404, and the clamping of the clamp body 4 causes the telescopic rod 403 to deform into a shape that matches the optical lens barrel or CAP, and the optical lens barrel or CAP is better clamped by the telescopic rod 403 and the anti-slip part 404. The force on the telescopic rod 403 will exert pressure on 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 installed on different stabilizing plates 402 are subjected to the same force. If the gravity sensing modules on different stabilizing plates 402 are subjected to different forces, it can be determined that the optical lens barrel or CAP is not parallel to the horizontal plane. By passing this parameter to the adjustment component, the position of the optical lens barrel or CAP is adjusted through the adjustment component to ensure that the optical lens barrel or CAP is level with the horizontal plane.

[0057] When the adjustment component is in use, the electric telescopic rod 7 will first push the stabilizing plate 402 to the end away from the clamping piece 401, so that the clamping piece 401 and the stabilizing plate 402 are separated by a distance, and then the ball 16 is rotated by the driving wheel 10 located in the vertical direction. After the vertical position change is completed, the ball 16 is rotated by the driving wheel 10 located in the horizontal direction, so that the ball 16 rotates with the electric telescopic rod 7, and the electric telescopic rod 7 changes the position of the stabilizing plate 402 to ensure that the CAP or the optical lens barrel is horizontal to the horizontal plane, avoiding the CAP or the optical lens barrel from tilting, resulting in the failure of the threaded fit between the CAP and the optical lens barrel, thereby avoiding the situation where the CAP and the optical lens barrel are pre-tightened unsuccessfully and affecting the production yield. The detection component 15 performs a secondary detection of the optical lens barrel and the CAP after the adjustment of the adjustment component is completed.

[0058] In addition, when the clamping piece 401 cannot operate normally, the optical lens barrel and the CAP can also be clamped by only driving the position of the stabilizing plate 402 by the electric telescopic rod 7, so that the clamping piece 401 can have a compensation function after being damaged.

[0059] The present invention provides a clamping piece 401 and a stabilizing plate 402, and provides an adjustment component capable of adjusting the stabilizing plate 402. The adjustment component ensures that the CAP and the optical lens barrel are always horizontal to the horizontal plane, and avoids that the threads of the CAP and the optical lens barrel cannot cooperate during the pre-tightening process, which affects the pre-tightening efficiency of the CAP and the optical lens barrel.
