[0027] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments 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 robot 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 unloading tray device installed on the machine platform 1 and located on the front side of the coupling fixture 3, a lens flatness visual inspection mechanism 5 installed on the machine platform 1 and located on the rear side of the coupling fixture 3, and two coupling devices 6 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 loading and unloading robot 2 picks up the coupling devices at the upper and lower material positions 10 and puts them on the coupling fixture 3. 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 efficiency of coupling. When all the coupling positions on the coupling device are coupled, the coupling fixture 3 releases the coupling device, and the loading and unloading robot 2 picks up the coupling device on the coupling fixture 3 and places it on 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 utility model not only performs coupling work simultaneously through the two coupling devices 6, but also realizes the automatic retraction and release of the material tray to realize the automatic feeding of the coupling device. The degree of automation is high, which greatly improves production efficiency and reduces labor costs and labor intensity.

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

[0031] In actual application, when the unloading storage tray layer 16 loaded with material trays is connected to the feed end of the conveying tray mechanism 7, the pushing mechanism 15 pushes the material trays in the unloading 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 unloading Z-axis moving mechanism 12 drives the unloading clamping mechanism 13 and the unloading box 14 to rise or fall the height of one unloading storage tray layer 16, so that the next unloading storage tray layer 16 is connected to the feed end of the conveying tray mechanism 7, and the pushing mechanism 15 can push the material trays in the unloading storage tray layer 16 onto the conveying tray mechanism 7. Of course, the unloading box 14 can supply 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 discharge box 14, the discharge X-axis moving mechanism 11 drives the discharge box 14 to move outward, so that the operator can replenish the material tray into the discharge box 14; in order to further improve production efficiency, after the discharge X-axis moving mechanism 11 drives the discharge box 14 to move outward, the discharge clamping mechanism 13 releases the clamping of the discharge box 14 to take out the empty discharge box 14, and then the fully loaded discharge box 14 is placed on the discharge clamping mechanism 13, and the discharge clamping mechanism 13 clamps the fully loaded discharge box 14 to realize the replacement of the discharge box 14.

[0032] In this 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 in the middle of the discharge end of the conveying tray mechanism 7. The material receiving box 20 is provided with multiple layers of material receiving storage tray layers 22. 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. 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 material tray conveying mechanism 7 conveys the material trays to the material storage tray layer 22 of the receiving box 20, and then the pushing mechanism 21 pushes the material trays to push the material trays into place, improving the positioning accuracy and stability of the material trays within the material storage tray layer 22. The material tray conveying mechanism 7 conveys the material trays layer by layer to the material storage tray layer 22 of the receiving box 20. Each time the receiving box 20 collects a material tray, the receiving box 20 will rise or fall by the height of the material storage tray layer 22. When the receiving box 20 is full of material trays, the receiving X-axis moving mechanism 17 drives the receiving box 20 to move outward, making it easier for the operator to remove the material trays in the receiving box 20, or for the receiving clamping mechanism 19 to release the clamping mechanism 19 on the receiving box 20 so that the operator can replace 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 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 operation, the push block 26 is erected and abuts the limit plate 28 under the elastic force of the elastic member 27. When the feeding tray mechanism 7 is conveying the material tray to the material storage tray layer 22 of the material receiving box 20, the moving material tray will abut the push block 26 and exert a force on the push block 26 to overcome the elastic force, causing the push block 26 to rotate from a vertical state to an inclined or horizontal state until the material tray passes the push block 26. The push block 26 will return to normal operation under the action of the elastic force. At this time, the push-in cylinder 24 drives the movable plate 25 and the push block 26 to move horizontally in the direction close to the material receiving box 20, so that the push block 26 pushes the material tray and pushes the material tray into position. The push-in mechanism 21 of this structural design not only does not interfere with the conveying of the material tray, but also can push the material tray into position normally.

[0036] Specifically, a guide slope is provided on the top of the push block 26; the movable material tray contacts the guide 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 provided above the shooting end of the first visual camera 29, and a second 45° reflector 33 is provided above the shooting end of the second visual camera 30. The shooting light reflected by the first visual camera 29 via the first 45° reflector 32, the shooting light reflected by the second visual camera 30 via the second 45° reflector 33 and the shooting light of the third visual camera 31 intersect and are perpendicular to each other.

[0038] In actual application, 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 to the coupling position of the coupling device, the light curing mechanism 42 light cures the glue on the coupling device after the lens is coupled.

[0041] In this embodiment, the Y-axis angular displacement platform 38 includes an X-axis drive mechanism 45 installed on the lifting base 37, a rotating plate 46 rotatably connected to the lifting base 37, a swing arm 47 connected to the rotating plate 46, a vertical guide rail 48 translationally arranged on the lifting base 37 and connected to the driving end of the X-axis drive mechanism 45, and a slider 49 slidably connected to the vertical guide rail 48. The 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 will drive the slider 49 to slide up and down along the vertical guide rail 48, and the swing arm 47 will rotate 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 screw rod 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 screw rod 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 screw rod 51 to rotate. The rotating X-axis screw rod 51 drives the moving nut 52 to move along the axial direction of the X-axis screw rod 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 making the upper clamping plate 58 and the lower clamping plate 59 loosen the feeding box 14. At this time, the feeding box 14 can be taken away.

[0048] Specifically, the top surface of the 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 upper positioning hole's concave and convex shape. The bottom surface of the 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 lower positioning hole's concave and convex shape. When the discharge clamping mechanism 13 clamps the discharge box 14, the upper positioning hole matches the upper positioning block's concave and convex shape, and the lower positioning hole matches the lower positioning block's concave and convex shape, thereby improving the stability and positioning accuracy of the discharge clamping mechanism 13 clamping the discharge box 14.

[0049] Specifically, the structure of the material receiving clamping mechanism 19 is the same as that of the material discharging clamping mechanism 13 , and the structure of the material receiving box 20 is the same as that of the material discharging box 14 , and the working principles are the same, which will not be repeated here.
