[0027] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0028] like Figures 1 to 7 As shown, the present invention provides a fully automatic lens coupling machine, which includes a machine platform 1, a loading and unloading manipulator 2 installed on the machine platform 1, a coupling fixture 3 installed on the machine platform 1, a lens carrier 4 arranged in parallel with the coupling fixture 3, a material receiving and releasing tray device installed on the machine platform 1 and located on the front side of the coupling fixture 3, a lens flatness visual detection mechanism 5 installed on the machine platform 1 and located on the rear side of the coupling fixture 3, and two coupling devices 6 respectively installed on the machine platform 1 and located on the left and right sides of the coupling fixture 3. The material tray collection and discharge device includes a conveying tray mechanism 7 installed on the machine 1, a discharge tray module 8 arranged on the feed side of the conveying tray mechanism 7, and a receiving tray module 9 arranged on the discharge side of the conveying tray mechanism 7. The middle part of the conveying tray mechanism 7 is provided with upper and lower material positions 10, and the loading and unloading manipulator 2 is movably arranged above the upper and lower material positions 10 and the coupling fixture 3; specifically, the lens flatness visual detection mechanism 5 is electrically connected to the coupling device 6, and the conveying direction of the conveying tray mechanism 7 is parallel to the Y-axis.

[0029] In actual application, the material tray module 8 supplies the material tray loaded with coupling devices (such as PCB boards, etc.) to the conveying material tray mechanism 7, and the conveying material tray mechanism 7 conveys the material tray to the upper and lower material positions 10. The upper and lower material robot 2 picks up the coupling devices at the upper and lower material positions 10 to the coupling fixture 3, and the coupling fixture 3 carries and clamps the coupling devices. Then, the two coupling devices 6 pick up the lenses on the lens carrier 4 respectively, and move the lenses to the lens flatness visual detection mechanism 5 according to the control process. The lens flatness visual detection mechanism 5 performs flatness detection on the lenses picked up by the coupling device 6 and feeds back the detection results to the corresponding coupling device 6, so that the coupling device 6 adjusts the flatness of the lens, and then the coupling device 6 couples the lens to the coupling position of the coupling device, thereby ensuring that the lens can be accurately coupled to the coupling device; wherein, the two coupling devices 6 work independently and do not interfere with each other, which greatly improves the coupling efficiency. When all the coupling positions on the coupling device are coupled, the coupling fixture 3 releases the coupling device, and the loading and unloading manipulator 2 picks up the coupling device on the coupling fixture 3 to the material tray of the upper and lower material positions 10. When all the coupling devices on the material tray are coupled, the conveying material tray mechanism 7 conveys the material tray to the receiving material tray module 9, and the receiving material tray module 9 recycles and stores the material tray. The present invention not only performs coupling work simultaneously through two coupling devices 6, but also realizes the automatic collection and release of the material tray to realize the automatic feeding of the coupling device. The degree of automation is high, which greatly improves the production efficiency and reduces the labor cost and labor intensity.

[0030] In this embodiment, the material discharge tray module 8 includes a material discharge X-axis moving mechanism 11, a material discharge Z-axis moving mechanism 12 installed at the moving end of the material discharge X-axis moving mechanism 11, a material discharge clamping mechanism 13 installed at the moving end of the material discharge Z-axis moving mechanism 12, a material discharge box 14 detachably connected to the clamping end of the material discharge clamping mechanism 13, and an ejection mechanism 15 installed on the side of the main body of the material discharge Z-axis moving mechanism 12 away from the conveying tray mechanism 7. The material discharge box 14 is provided with a plurality of layers of material discharge storage tray layers 16, and the material discharge storage tray layers 16 are used to store material trays. The feeding end of the conveying tray mechanism 7 is used to connect with the material discharge storage tray layer 16, and the ejection mechanism 15 is used to push the material tray in the material discharge storage tray layer 16 onto the conveying tray mechanism 7.

[0031] In practical applications, when the material storage tray layer 16 loaded with material trays is connected with the feed end of the conveying tray mechanism 7, the push-out mechanism 15 pushes the material trays in the material storage tray layer 16 onto the conveying tray mechanism 7, and the conveying tray mechanism 7 conveys the material trays; when it is necessary to supply the next material tray to the conveying tray mechanism 7, the material discharge Z-axis moving mechanism 12 drives the material discharge clamping mechanism 13 and the material discharge box 14 to raise or lower the height of a material storage tray layer 16, so that the next material discharge storage tray layer 16 is connected with the feed end of the conveying tray mechanism 7, and the push-out mechanism 15 can push the material trays in the material storage tray layer 16 onto the conveying tray mechanism 7. Of course, the material discharge box 14 can supply the material trays to the conveying tray mechanism 7 by rising layer by layer from bottom to top, or by descending layer by layer from top to bottom. When there is no material tray in the material discharge box 14, the material discharge X-axis moving mechanism 11 drives the material discharge box 14 to move outward, so that the operator can add material trays to the material discharge box 14; in order to further improve the production efficiency, after the material discharge X-axis moving mechanism 11 drives the material discharge box 14 to move outward, the material discharge clamping mechanism 13 releases the clamping of the material discharge box 14 to take out the empty material discharge box 14, and then the fully loaded material discharge box 14 is placed on the material discharge clamping mechanism 13, and the material discharge clamping mechanism 13 clamps the fully loaded material discharge box 14 to realize the replacement of the material discharge box 14.

[0032] In the present embodiment, the material receiving tray module 9 includes a material receiving X-axis moving mechanism 17, a material receiving Z-axis moving mechanism 18 installed at the moving end of the material receiving X-axis moving mechanism 17, a material receiving clamping mechanism 19 installed at the moving end of the material receiving Z-axis moving mechanism 18, a material receiving box 20 detachably connected to the clamping end of the material receiving clamping mechanism 19, and a pushing-in-place mechanism 21 arranged at the middle of the discharge end of the conveying tray mechanism 7. The material receiving box 20 is provided with a plurality of layers of material receiving storage tray layers 22, and the material receiving storage tray layers 22 are used to store material trays. The discharge end of the conveying tray mechanism 7 is used to connect with the material receiving storage tray layer 22, and the pushing-in-place mechanism 21 is used to push the material tray transported by the conveying tray mechanism 7 to the material receiving storage tray layer 22 into place.

[0033] The working principle of the receiving tray module 9 is similar to that of the discharging tray module 8, so it will not be described in detail. In actual application, the conveying tray mechanism 7 conveys the tray to the receiving tray layer 22 of the receiving box 20, and then the pushing mechanism 21 pushes the tray to push the tray into place, thereby improving the position accuracy and stability of the tray in the receiving tray layer 22; the conveying tray mechanism 7 conveys the tray to the receiving tray layer 22 of the receiving box 20 layer by layer, and each time the receiving box 20 recovers a tray, the receiving box 20 will rise or fall by the height of a receiving tray layer 22. When the receiving box 20 is fully loaded with trays, the receiving X-axis moving mechanism 17 drives the receiving box 20 to move outward, so that the operator can take out the tray in the receiving box 20, or the receiving clamping mechanism 19 releases the clamping of the receiving box 20, and the operator replaces the receiving box 20.

[0034] In this embodiment, the pushing-in-place mechanism 21 includes a fixed seat 23 embedded in the middle of the conveying tray mechanism 7, a pushing-in-place cylinder 24 installed on the fixed seat 23, a movable plate 25 of the piston rod installed on the pushing-in-place cylinder 24, a pushing block 26 rotatably connected to the movable plate 25 in the middle, an elastic member 27 elastically connected between the bottom of the pushing block 26 and the movable plate 25, and a limiting plate 28 arranged on the fixed seat 23. The pushing block 26 is erected and abuts against the limiting plate 28 under the elastic force of the elastic member 27, and the top of the erected pushing block 26 extends out above the conveying surface of the conveying tray mechanism 7; specifically, the elastic member 27 can be an elastic pull belt or a tension spring.

[0035] In normal state, the push block 26 stands upright and contacts the limit plate 28 under the elastic force of the elastic member 27. When the feeding tray mechanism 7 is feeding the feeding tray into the receiving storage tray layer 22 of the receiving box 20, the moving feeding tray will contact the push block 26 and exert a force to overcome the elastic force on the push block 26, so that the push block 26 rotates from a vertical state to an inclined or horizontal state, until the feeding tray passes the push block 26, and the push block 26 returns to normal state under the elastic force. At this time, the push-in-place cylinder 24 drives the moving plate 25 and the push block 26 to move in a direction close to the receiving box 20, so that the push block 26 pushes the feeding tray and pushes the feeding tray into place. The push-in-place mechanism 21 of this structural design not only does not interfere with the feeding of the feeding tray, but also can push the feeding tray into place normally.

[0036] Specifically, a guiding slope is provided on the top of the push block 26; the moving material tray contacts the guiding slope, which facilitates the material tray to drive the push block 26 to rotate so as to facilitate the contact push block 26 to rotate from a vertical state to an inclined or horizontal state, and reduce the friction resistance and wear between the material tray and the push block 26.

[0037] In this embodiment, the lens flatness visual inspection mechanism 5 includes a first visual camera 29, a second visual camera 30 and a third visual camera 31 respectively installed on the machine 1. The first visual camera 29, the second visual camera 30 and the third visual camera 31 are not on the same straight line. A first 45° reflector 32 is arranged above the shooting end of the first visual camera 29, and a second 45° reflector 33 is arranged above the shooting end of the second visual camera 30. The shooting light reflected by the first 45° reflector 32 of the first visual camera 29, the shooting light reflected by the second 45° reflector 33 of the second visual camera 30 and the shooting light of the third visual camera 31 intersect and are perpendicular to each other.

[0038] In actual applications, after the coupling device 6 picks up the lens, it moves to the flatness visual detection area formed by the first visual camera 29, the second visual camera 30 and the third visual camera 31. The first visual camera 29, the second visual camera 30 and the third visual camera 31 cooperate to detect the flatness of the lens and feed back the flatness detection result to the coupling device 6, so that the coupling device 6 adjusts the position and angle (flatness) of the lens according to the flatness detection result to ensure the flatness of the lens.

[0039] In this embodiment, the coupling device 6 includes a coupling X-axis moving mechanism 34 installed on the machine 1, a coupling Y-axis moving mechanism 35 installed on the moving end of the coupling X-axis moving mechanism 34, a coupling Z-axis moving mechanism 36 installed on the moving end of the coupling Y-axis moving mechanism 35, a lifting seat 37 installed on the moving end of the coupling Z-axis moving mechanism 36, a Y-axis angular displacement platform 38 installed on the lifting seat 37, a Z-axis angular displacement platform 39 installed at the angular displacement end of the Y-axis angular displacement platform 38, an X-axis angular displacement platform 40 installed at the angular displacement end of the Z-axis angular displacement platform 39, a clamping mechanism 41 installed at the angular displacement end of the X-axis angular displacement platform 40, a light curing mechanism 42 arranged on the main body of the clamping mechanism 41, and a dispensing mechanism 43 and a visual positioning mechanism 44 respectively installed on the lifting seat 37 and located above the clamping mechanism 41. Specifically, the X-axis angular displacement platform 40 is an X-axis angular displacement slide that can provide rotational motion around the X-axis, the Y-axis angular displacement platform 38 is a Y-axis angular displacement slide that can provide rotational motion around the Y-axis, and the Z-axis angular displacement platform 39 is a Z-axis angular displacement slide that can provide rotational motion around the Z-axis.

[0040] In actual application, the clamping mechanism 41 clamps the lens, and the coupling X-axis moving mechanism 34, the coupling Y-axis moving mechanism 35 and the coupling Z-axis moving mechanism 36 cooperate to adjust the position of the lens and complete the coupling action. According to the lens flatness detection result, the Y-axis angular displacement platform 38, the Z-axis angular displacement platform 39 and the X-axis angular displacement platform 40 cooperate to adjust the flatness of the lens; the visual positioning mechanism 44 is used to visually locate the coupling position of the coupling device, and the glue dispensing mechanism 43 is used to dispense glue at the coupling position of the coupling device. After the clamping mechanism 41 couples the lens at the coupling position of the coupling device, the light curing mechanism 42 performs light curing on the glue on the coupling device after the coupling lens.

[0041] In this embodiment, the Y-axis angular displacement platform 38 includes an X-axis driving mechanism 45 installed on the lifting seat 37, a rotating plate 46 rotatably connected to the lifting seat 37, a swing arm 47 connected to the rotating plate 46, a vertical guide rail 48 translationally arranged on the lifting seat 37 and connected to the driving end of the X-axis driving mechanism 45, and a slider 49 slidably connected to the vertical guide rail 48, one end of the swing arm 47 away from the rotating plate 46 is rotatably connected to the slider 49, and the Z-axis angular displacement platform 39 is installed on the rotating plate 46.

[0042] In practical applications, the X-axis drive mechanism 45 drives the vertical guide rail 48 to reciprocate along the X-axis. The reciprocating vertical guide rail 48 drives the slider 49 to slide up and down along the vertical guide rail 48, and the swing arm 47 rotates relative to the slider 49. The rotating swing arm 47 drives the rotating plate 46 to rotate around the Y-axis, thereby driving the Z-axis angular displacement platform 39 to rotate around the Y-axis, and further adjusting the angle of the lens clamped by the clamping jaw mechanism 41.

[0043] In this embodiment, the X-axis drive mechanism 45 includes an X-axis motor 50 installed on the lifting seat 37, an X-axis lead screw 51 rotatably connected to the lifting seat 37 and drivingly connected to the output shaft of the X-axis motor 50, a moving nut 52 threadedly sleeved on the X-axis lead screw 51, and a translation seat 53 installed on the moving nut 52 and slidably connected to the lifting seat 37. The vertical guide rail 48 is installed on the translation seat 53.

[0044] In practical applications, the X-axis motor 50 drives the X-axis lead screw 51 to rotate. The rotating X-axis lead screw 51 drives the moving nut 52 to move along the axial direction of the X-axis lead screw 51. The moving moving nut 52 drives the translation seat 53 and the vertical guide rail 48 to translate.

[0045] In this embodiment, the pushing mechanism 15 includes a Y-axis drive mechanism 54 installed on the side of the main body of the feeding Z-axis moving mechanism 12 away from the conveying tray mechanism 7, and a push rod 55 installed on the driving end of the Y-axis drive mechanism 54. The push rod 55 can extend into the feeding storage tray layer 16. In practical applications, the Y-axis drive mechanism 54 drives the push rod 55 to reciprocate, so that the push rod 55 can push out the trays in the feeding box 14 layer by layer.

[0046] In this embodiment, the feeding clamping mechanism 13 includes a U-shaped plate 56 installed on the moving end of the feeding Z-axis moving mechanism 12, a clamping driver 57 installed on the top plate of the U-shaped plate 56, an upper clamping plate 58 installed on the driving end of the clamping driver 57, and a lower clamping plate 59 installed on the bottom plate of the U-shaped plate 56. The upper clamping plate 58 and the lower clamping plate 59 are arranged opposite to each other. The clamping driver 57 is used to drive the upper clamping plate 58 to approach or move away from the lower clamping plate 59; the upper clamping plate 58 and the lower clamping plate 59 cooperate to clamp the feeding box 14; specifically, the clamping driver 57 can adopt a vertically downward cylinder.

[0047] In practical applications, when the feeding box 14 needs to be replaced, the clamping driver 57 drives the upper clamping plate 58 to rise, so that the upper clamping plate 58 is separated from the feeding box 14, thereby enabling the upper clamping plate 58 and the lower clamping plate 59 to release the feeding box 14. At this time, the feeding box 14 can be taken away.

[0048] Specifically, the top surface of the material discharge box 14 is provided with an upper positioning hole, and the bottom surface of the upper clamping plate 58 is provided with an upper positioning block that matches the concave and convex of the upper positioning hole; the bottom surface of the material discharge box 14 is provided with a lower positioning hole, and the top surface of the lower clamping plate 59 is provided with a lower positioning block that matches the concave and convex of the lower positioning hole. When the material discharge clamping mechanism 13 clamps the material discharge box 14, the upper positioning hole matches the concave and convex of the upper positioning block, and the lower positioning hole matches the concave and convex of the lower positioning block, so as to improve the stability and position accuracy of the material discharge clamping mechanism 13 clamping the material discharge box 14.
