[0042] See Figures 1 to 7 As shown in the drawings, the present application provides a riveting device for riveting blades 10 of a lens, the blades 10 having a first rivet hole 12 and a second rivet hole 14. The riveting device includes a first positioning module 16, a first rotary feeding table 18, a first riveting rotary table 20, a first rivet feeding unit 22, and a first riveting machine 24. The first rotary feeding table 18 is arranged with a plurality of blades 10 to be riveted. The first rivet feeding unit 22 delivers a first rivet 26 to a riveting position of a blade 10 on the first riveting rotary table 20. The first positioning module 16 adsorbs a blade 10 and places the blade 10 at a predetermined position of the first riveting rotary table 20, so that the first rivet hole 12 corresponds to the first rivet 26. The first riveting machine 24 rivets the first rivet 26 to the first rivet hole 12.

[0043] The riveting device further includes a gas jet unit 28 having a gas jet port 30 facing the blades 10. When the first positioning module 16 adsorbs a blade 10, the gas jet unit 28 jets gas to the blade 10 to prevent adhesion of adjacent blades 10. The gas jet port 30 on one side of the blade 10 continuously jets gas, thereby separating two adjacent blades 10 and avoiding the phenomenon of simultaneously adsorbing two blades 10 caused by adhesion between thin-walled parts.

[0044] The blades 10 to be riveted in this embodiment are substantially arc-shaped thin sheets, and two rivets are riveted on both sides of the blades 10.

[0045] In the preferred embodiment, the automatic riveting of the blade 10 and the rivet is realized by setting the first positioning module 16, the first rotary feeding table 18, the first riveting rotary table 20, the first rivet feeding unit 22 and the first riveting machine 24, which greatly speeds up the production. In addition, the air jet port 30 is arranged towards the blade 10, so that when the first positioning module 16 adsorbs the blade 10, the air jet unit 28 sprays air to the blade 10 to prevent adjacent blades 10 from sticking, thereby further solving the problem of difficult separation between adjacent blades 10, and further improving the production efficiency.

[0046] The first rotary feeding table 18 is provided with a blade stacking support 32, which stacks a plurality of blades 10 in the vertical direction. The blade stacking support 32 includes two limiting rods 34 abutting against the outer periphery of the blade 10, and two positioning rods 36 respectively penetrating the first rivet hole 12 and the second rivet hole 14.

[0047] Further, the riveting device further comprises an auxiliary push rod 38, which supports a plurality of blades 10 in the blade stacking support 32 in the vertical direction. And the auxiliary push rod 38 can move up and down in the vertical direction, so that the uppermost blade 10 is always in the uppermost position of the blade stacking support 32, that is, always in the adsorption position.

[0048] The blade stacking support 32 is arranged in a circumferential array on the first rotary feeding table 18. When the blades 10 on a certain blade stacking support 32 are taken, the first rotary feeding table 18 is rotated by a certain angle, so that the blades 10 on the next blade stacking support 32 can be taken.

[0049] Further, the riveting device further comprises a first microscopic vision unit 40. The first positioning module 16 comprises a first blade suction head 42, and a first vision positioning hole 44 is arranged at the first blade suction head 42. When the first blade suction head 42 adsorbs a blade 10, the first microscopic vision unit 40 captures the blade 10 through the first vision positioning hole 44, so that the first vision positioning hole 44 is aligned with the first rivet hole 12, and according to the image information, the first positioning module 16 drives the blade 10 to a predetermined position of the first riveting rotary table 20, so that the first rivet hole 12 corresponds to the first rivet 26, and the first riveting machine 24 rivets the first rivet 26 in the first rivet hole 12.

[0050] Due to the setting of the first microscopic vision unit 40, the centering of the rivet hole on the blade 10 and the rivet can be accurately realized, thereby greatly improving the assembly efficiency and the yield.

[0051] The riveting device further comprises an adsorption position correction table 46, two pins are arranged on the adsorption position correction table 46, the relative position relationship of the two pins is the same as that of the first rivet hole 12 and the second rivet hole 14, after the first blade adsorption head 42 adsorbs the blade 10, the blade 10 is moved to the adsorption position correction table 46, and the adsorption position is corrected by using the position corresponding relationship between the two pins and the first rivet hole 12 and the second rivet hole 14. Since the adsorption position correction table 46 is arranged, the adsorption position can be corrected again to avoid the existence of the adsorption position deviation.

[0052] The riveting device further comprises a second positioning module 48, a blade overturning mechanism 50, a second riveting rotating table 52, a second rivet feeding unit 54 and a second riveting machine 56, the blade overturning mechanism 50 adsorbs the blade 10 riveted with a rivet and overturns the blade 10 by 180 degrees, the second rivet feeding unit 54 feeds the second rivet 57 to the riveting position on the second riveting rotating table 52, the second positioning module 48 adsorbs the blade 10 overturned by 180 degrees to the second riveting rotating table 52 and makes the second rivet hole 14 correspond to the second rivet 57, and the second riveting machine 56 rivets the second rivet 57 in the second rivet hole 14.

[0053] Further, the blade overturning mechanism 50 comprises a blade overturning adsorption head 58 adsorbing the blade 10, an overturning swing cylinder 60 driving the blade overturning adsorption head 58 to overturn, and a overturning mechanism linear module 62 transferring the blade 10.

[0054] Specifically in the embodiment, the first positioning module 16 and the second positioning module 48 have the same structure, the first riveting rotating table 20 and the second riveting rotating table 52 have the same structure, the first rivet feeding unit 22 and the second rivet feeding unit 54 have the same structure, and the first riveting machine 24 and the second riveting machine 56 have the same structure. Of course, the first positioning module 16 and the second positioning module 48 can also have different structures, the first riveting rotating table 20 and the second riveting rotating table 52 can also have different structures, the first rivet feeding unit 22 and the second rivet feeding unit 54 can also have different structures, and the first riveting machine 24 and the second riveting machine 56 can also have different structures.

[0055] Further, the riveting device further comprises a second microscopic vision unit 64, the second positioning module 48 comprises a second blade suction head 66, and a second vision positioning hole 68 is arranged at the second blade suction head 66. When the second blade suction head 66 adsorbs the blade 10 which is turned over by 180 degrees, the second microscopic vision unit 64 takes a picture of the blade 10 through the second vision positioning hole 68, and drives the second positioning module 48 to drive the blade 10 to a predetermined position of the second riveting rotary table 52 according to the image information, and makes the second rivet hole 14 correspond to the second rivet 57. The second riveting machine 56 rivets the second rivet 57 in the second rivet hole 14.

[0056] Since the first rivet feeding unit 22 and the second rivet feeding unit 54 have the same structure, only the first rivet feeding unit 22 will be described in detail below, and the second rivet feeding unit 54 will not be specifically introduced.

[0057] Further referring to Figures 8 to 16 , the first rivet feeding unit 22 comprises an automatic sorting vibration disc 70, a rivet inserting mechanism 72 for inserting the first rivet 26 into the first rivet hole 12, and a conveying mechanism arranged between the automatic sorting vibration disc 70 and the rivet inserting mechanism 72. The conveying mechanism conveys the first rivet 26 from the automatic sorting vibration disc 70 to the rivet inserting mechanism 72.

[0058] Specifically, in this embodiment, the output port of the automatic sorting vibration disc 70 is provided with a rivet feeding groove 74, and the conveying mechanism comprises a rivet taking plate 78 provided with a taking groove 76, and a rivet taking cylinder 80 for driving the rivet taking plate 78 to reciprocate. When the position of the taking groove 76 corresponds to the rivet feeding groove 74, a rivet enters the taking groove 76. The rivet taking cylinder 80 drives the rivet taking plate 78 to move so that the taking groove 76 drives the rivet to the riveting position, and then the rivet inserting mechanism 72 pushes the rivet down.

[0059] Preferably, the reciprocating direction of the rivet taking plate 78 is perpendicular to the extension direction of the rivet feeding groove 74.

[0060] A plurality of riveting bases 82 are arranged along the circumference on the first riveting rotary table 20, that is, a plurality of riveting stations are arranged on the first riveting rotary table 20, and the blade 10 and the rivet are riveted on the riveting base 82.

[0061] When the rivet is fed, the rivet is first sorted and screened by the automatic sorting vibration disc 70, and then is conveyed to the material taking groove 76 and the riveting plug-in mechanism 72 through the rivet conveying groove 74. The rivet material taking plate 78 provided with the material taking groove 76 reciprocates under the pushing of the rivet material taking cylinder 80. When the material taking groove 76 moves to the end of the rivet conveying groove 74, the material taking groove 76 carries a rivet to the position directly above the riveting base 82 on the first riveting rotary table 20. Then, the top rod at the end of the riveting plug-in mechanism 72 pushes the rivet in the material taking groove 76 into the round hole of the riveting base 82, and the rivet feeding work is completed. The rivet and the material taking groove 76 have a certain interference amount. In this way, the rivet will not fall from the material taking groove 76 without external force.

[0062] The riveting device also comprises a discharging mechanism 84 and a storage disc 86. The discharging mechanism 84 is provided with a discharging suction head 88, which adsorbs the blade 10 riveted with two rivets and conveys the blade 10 from the second riveting rotary table 52 to the storage disc 86.

[0063] The first microscopic vision unit 40 comprises a vision camera 41 and a light source 43.

[0064] The embodiment also provides a first riveting method for riveting the lens blade 10. The first riveting method comprises the following steps:

[0065] The first positioning module 16, the first rotary feeding table 18, the first microscopic vision unit 40, the first riveting rotary table 20, the first rivet feeding unit 22 and the first riveting machine 24 are provided;

[0066] The first positioning module 16 adsorbs the blade 10 on the first rotary feeding table 18;

[0067] The first rivet feeding unit 22 conveys the first rivet 26 to the riveting position on the first riveting rotary table 20;

[0068] The action of the first positioning module 16 adsorbing the blade 10 and the action of the first rivet feeding unit 22 conveying the first rivet 26 are performed synchronously. The first vision positioning hole 44 is arranged at the first blade suction head 42. When the first blade suction head 42 adsorbs a blade 10, the first microscopic vision unit 40 photographs the blade 10 through the first vision positioning hole 44, so that the first vision positioning hole 44 is aligned with the first rivet hole 12, and according to the image information, the first positioning module 16 drives the blade 10 to the predetermined position of the first riveting rotary table 20, i.e. the corresponding position on the riveting base 82, so that the first rivet hole 12 corresponds to the first rivet 26, and the first riveting machine 24 rivets the first rivet 26 in the first rivet hole 12.

[0069] During the loading of the blade 10, first, the first blade suction head 42 is moved to the field of view of the visual camera, and does not hinder the visual camera from identifying the position of the rivet. Since the first visual positioning hole 44 is large, and after the blade 10 is corrected by the adsorption pose correction table 46, the camera can directly shoot the image of the first rivet hole 12 at one end of the blade 10 through the first visual positioning hole 44. Then, the image processing is performed to obtain the position of the center of the first rivet hole 12 at one end of the blade 10 and the position of the center of the upper surface of the rivet in the same field of view. According to the positional relationship between the two, the first positioning module 16 drives the first blade suction head 42 to complete the centering of the first rivet hole 12 and the rivet on the blade 10, and places the blade 10 on the riveting base 82 to complete the accurate assembly between the blade 10 and the rivet.

[0070] Specifically, after the assembly of the blade 10 and the rivet on the riveting base 82 is completed, the first riveting rotary table 20 carries the riveting base 82 to rotate to the position directly below the riveting head of the first riveting machine 24 to perform riveting, and the riveting work on one side of the blade 10 is completed.

[0071] After the riveting on one side is completed, next, the riveting method further includes the following steps: the first riveting rotary table 20 carries the blade 10 riveted with one rivet to the loading position of the blade turnover mechanism 50, the blade 10 is adsorbed by the blade turnover suction head 58, is taken off from the riveting base 82, and is turned over by 180 degrees so that the other side of the blade 10 faces upward. Then, the linear module 62 of the turnover mechanism transfers the blade 10 to the side for the second riveting, the second blade suction head 66 driven by the second positioning module 48 takes the blade 10 off from the blade turnover suction head 58, and performs the same centering and assembly operation as when the first rivet is installed directly below the second microscopic visual unit 64. Then, the same riveting process as when the first rivet is riveted is performed, so that the second rivet is riveted on the other side of the blade 10.

[0072] After the riveting process on both sides is completed, the micro-assembly process of the blade 10 is completed, the finished product is taken off from the riveting base 82 by the unloading suction head 88 in the unloading mechanism 84, and is transported to the storage tray 86.

[0073] Since the riveting bases 82 on the first riveting rotary table 20 and the second riveting rotary table 52 are respectively arranged in a circular array, a plurality of riveting bases 82 are arranged, that is, a plurality of assembly positions are arranged, and the above steps can be performed at the same time, so that the assembly efficiency is greatly improved.

[0074] The embodiment also provides a second riveting method for riveting the blade 10 for the lens, and the blade 10 has a first rivet hole 12 and a second rivet hole 14. The second riveting method includes the following steps:

[0075] The first positioning module 16, the first rotary feeding table 18, the first riveting rotary table 20, the first rivet feeding unit 22 and the first riveting machine 24 are provided;

[0076] The first positioning module 16 adsorbs the vane 10 on the first rotary feeding table 18, and the air jet unit 28 sprays air to the vane 10 to prevent adjacent vanes 10 from sticking while the first positioning module 16 adsorbs the vane 10;

[0077] The first rivet feeding unit 22 delivers the first rivet 26 to the riveting position on the first riveting rotary table 20;

[0078] The action of the first positioning module 16 adsorbing the vane 10 and the action of the first rivet feeding unit 22 delivering the first rivet 26 are performed synchronously, the first positioning module places the vane 10 at a predetermined position of the first riveting rotary table 20, i.e., a corresponding position of the riveting base 82, so that the first rivet hole 12 corresponds to the first rivet 26, and the first riveting machine 24 rivets the first rivet 26 to the first rivet hole 12.

[0079] The next riveting step of the second riveting method is the same as that of the first riveting method.

[0080] The above is only one specific embodiment of the present application, and any improvement made on the basis of the concept of the present application is considered to be within the protection scope of the present application.
