[0063] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0064] Example 1: See Figures 1 to 9 As shown, a fully automatic lens packaging machine comprises a frame 1, a lens conveying mechanism 2 mounted on the frame, a lens power measuring instrument 3, a bag placing mechanism 4, a printing and labeling mechanism 5, a film loading mechanism 6 and a finished product warehouse 7. A controller is also provided, which is electrically connected to the lens conveying mechanism, the lens power measuring instrument, the bag placing mechanism, the printing and labeling mechanism, the film loading mechanism and the finished product warehouse, and controls the operation of the lens conveying mechanism, the lens power measuring instrument, the bag placing mechanism, the printing and labeling mechanism, the film loading mechanism and the finished product warehouse.

[0065] in: Lens power measuring instrument :

[0066] See also Figure 1 As shown, the lens power measuring instrument is arranged at the middle of the lens conveying mechanism, and is used to detect the power of the lens conveyed on the lens conveying mechanism. A detection notch is arranged at the front end of the lens power measuring instrument, and detection components are respectively arranged at the top and bottom of the detection notch.

[0067] Lens conveying mechanism:

[0068] The lens conveying mechanism is used for conveying lenses;

[0069] See also Figures 1 to 4As shown, the lens conveying mechanism 2 includes a first conveying mechanism 21, and the first conveying mechanism 21 includes two first conveying belts 210 parallel to each other, and there is a longitudinal spacing between the two first conveying belts 210, and the middle of the longitudinal spacing has a detection position;

[0070] The rear end of the lens power measuring instrument 3 is installed on the rear side of the middle part of the first conveying mechanism 21, and the front end of the lens power detector 3 is arranged opposite to the detection position. The middle part of the first conveying mechanism passes through the detection gap, and the detection components are respectively located above and below the detection position. The front and rear end bottoms of the lens are respectively conveyed by two first conveyor belts, and the detection position is located in the longitudinal spacing between the two first conveyor belts, and the two detection components are respectively located above and below the detection position. The top surface of the first conveyor belt is conveyed from left to right, and the lens is conveyed from the left side of the first conveyor belt to the right. When passing through the detection position, it is in the detection gap, and the lens is facing the two detection components. The two detection components of the lens power measuring instrument are used to detect the power of the lens.

[0071] See also Figure 1 , 4 As shown, a lens centering mechanism is also provided at the detection position. The lens centering mechanism includes a centering cylinder 22 and two sets of centering parts 23. The centering cylinder 22 is installed on the frame 1 and is arranged directly above the first conveying mechanism. The two sets of centering parts are arranged at intervals in front and back. The centering cylinder drives the two sets of centering parts to approach or move away from each other at the same time. When the two sets of centering parts move away from each other, the two sets of centering parts are located above the front side and above the rear side of the first conveying mechanism. The first conveying mechanism can normally convey the lens to move to the right. When it moves to the detection position, a sensor is set on the frame to detect whether the lens moves to this position. After moving to this position, the first conveyor belt stops working, and the output shaft of the centering cylinder retracts, driving the two sets of centering parts to approach each other, clamping the lens, so that the lens is centered and facing the lens degree measuring instrument, so that the lens degree measuring instrument can accurately detect the degree of the lens.

[0072] The centering member 23 includes two centering rods 231 and a centering rod connecting plate 232 which are arranged at intervals on the left and right. The left end of the centering rod connecting plate is connected to the output shaft of the centering cylinder (the front and rear ends of the centering cylinder are provided with output shafts). The left ends of the centering rod connecting plates of the two groups of centering members are respectively connected to the output shafts of the front and rear ends of the centering cylinder. The two centering rods are arranged at intervals on the left and right, and the top of the centering rod is rotatably connected to the bottom of the centering rod connecting plate. When the output shaft of the centering cylinder retracts, the two groups of centering members are driven to approach each other, and the lens is pushed to the center through the four centering rods, which is convenient for degree detection and ensures the accuracy of degree detection. At the same time, since the centering rod and the centering rod connecting plate are rotatably connected, the lens will not be damaged when it is centered.

[0073] Furthermore, the lens conveying mechanism 2 also includes a second conveying mechanism 24, which is arranged on the front side of the first conveying mechanism 21, and the second conveying mechanism 24 includes a second conveying belt 241. A material transfer mechanism 25 is also provided between the first conveying mechanism 21 and the second conveying mechanism 24, and the material transfer mechanism 25 grabs the lenses on the second conveying belt 241 and places them on the first conveying mechanism 21.

[0074] In order to shorten the length of the first conveying mechanism, a second conveying belt is also arranged at the front side of the lens conveying mechanism. The top surface of the second conveying belt is conveyed from right to left. A barrier is arranged at the top left end of the second conveying belt to prevent the lens from falling from the second conveying belt. The material transfer mechanism 25 includes a rotary drive member 251, a vertical rod 252, a material transfer cylinder 253 and a material transfer suction cup 254. The rotary drive member is mounted on the frame. The rotary drive member adopts a rotary cylinder or a rotary motor. The bottom of the vertical rod is connected to the driving end of the rotary drive member. The vertical rod is arranged between the first conveying mechanism and the second conveying mechanism and is arranged close to the left end. The material transfer cylinder is mounted on the upper side wall of the vertical rod. The top of the material transfer suction cup is connected to the output shaft at the bottom of the material transfer cylinder. When material transfer is required, the rotary drive member drives the vertical rod to rotate 180 degrees, so that the material transfer suction cup is directly above the left end of the second conveyor belt, and then the output shaft of the material transfer cylinder extends to drive the material transfer suction cup to move downward to absorb a lens on the second conveyor belt, and then the output shaft of the material transfer cylinder retracts to drive the lens to move up and off the second conveyor belt, and the rotary drive member drives the vertical rod to rotate 180°, so that the lens rotates to directly above the first conveying mechanism, and then the output shaft of the material transfer cylinder extends to drive the material transfer suction cup and the lens to move downward and close to the first conveying mechanism, and the material transfer suction cup releases the adsorption force of the lens, and the real-time lens falls onto the first conveying mechanism, and the lens is sent away by the first conveying mechanism.

[0075] See also Figure 1 , 2 As shown, a material placing tray 26 is also provided at the front side of the second conveying mechanism 24. With the setting of the material placing tray, more lenses can be placed in the material placing tray, and then the lenses are placed one by one on the right end of the second conveying belt. In this way, the space occupied, the materials used and the cost can be reduced.

[0076] Bag placing mechanism :

[0077] The bag placing mechanism 4 is disposed at the rear side of the end of the lens conveying mechanism 2 and is used for storing and releasing the lens packaging bag 11 .

[0078] See also Figure 1 , 2As shown in Figures 6 and 7, the bag placing mechanism 4 includes a bag frame component 41, a bag taking component 42, a positioning component 43 and a bag guiding component 44. The bag frame component 41, the bag taking component 42 and the positioning component 43 are arranged above the rear side of the end of the lens conveying mechanism 2, the middle part of the bag guiding component 44 is arranged directly above the end of the lens conveying mechanism 2, the rear end of the bag guiding component 44 is arranged directly below the positioning component 43, and the front end of the bag guiding component 44 is arranged above the front side of the end of the lens conveying mechanism 2.

[0079] A plurality of lens packaging bags are pre-placed in the bag frame component, and the bag taking component takes out one lens packaging bag from the bag frame component each time and releases it, so that the lens packaging bag falls downward onto the positioning component. After the lens packaging bag falls onto the positioning component, the printing and labeling mechanism prints out the degree information of the lens measured by the lens degree measuring instrument, and then affixes the label paper of the printed information on the lens packaging bag (the lens with the printed degree information will be loaded into the lens packaging bag with the printed information), and then the positioning component releases the lens packaging bag, and sends the lens packaging bag into the loading mechanism through the bag guiding component, and the detected lens is loaded into the lens packaging bag through the loading mechanism.

[0080] See also Figure 6 , 7 As shown, the bag frame component 41 includes a bag frame 410, a bag pushing block 411 and a bag limiting plate 412. A bag placing cavity 413 is provided on the top of the bag frame 410. The bottom surface of the bag placing cavity 413 is inclined downward from the back to the front. The front end of the bag placing cavity 413 is connected to the front end surface of the bag frame 410. The bag limiting plate 412 consists of two pieces, which are respectively arranged on both sides of the front end of the bag placing cavity 413. The bag pushing block 411 is slidably set in the bag placing cavity 413 at the rear end of the bag limiting plate 412.

[0081] The bag picking component 42 is arranged directly in front of the bag placing cavity 413, and the bag picking component 42 includes a bag picking suction cup 420 and a bag picking cylinder 421. The bag picking suction cup 420 is connected to the output shaft of the bag picking cylinder 421 via a first mounting plate 422, and the bag picking cylinder 421 drives the bag picking suction cup 420 to be inserted into the bag placing cavity 413, or to move forward to leave the bag placing cavity 413.

[0082] In this embodiment, the lens packaging bags are stacked from the back to the front and are located between the bag limiting plate and the bag pushing block. There is a distance between the two bag limiting plates, and the bag taking suction cup is arranged opposite to the lens packaging bags between the two limiting plates. Since the bag pushing block has a certain weight, it will automatically slide forward and press all the lens packaging bags forward, so that the two sides of the frontmost lens packaging bag are limited by the two bag limiting plates and will not fall. The bag taking cylinder is arranged longitudinally, and its output shaft is arranged opposite to the bag placing cavity of the bag frame. When the bag needs to be taken, the output shaft of the bag taking cylinder extends out, driving the bag taking suction cup to move backward and abut against the front side wall of the lens packaging bag at the front side (the bag taking suction cup is between the two bag limiting plates at this time), and the bag taking suction cup generates suction to suck the lens packaging bag at the front side, and then the output shaft of the bag taking cylinder retracts, and the two sides of the lens packaging bag sucked by the bag taking suction cup are deformed and separated from the two bag limiting plates to the front side of the bag frame, and then the bag taking suction cup releases the suction of the lens packaging bag, and the lens packaging bag will automatically fall downward to the positioning component under the weight. In this bag taking method, automatic bag taking can be realized, and only one lens packaging bag is taken at a time. After one lens packaging bag is taken away, the bag pushing block will push the lens packaging bag in the bag placing cavity forward, so that the lens packaging bag at the front side abuts against the two bag limiting plates and is limited by the bag limiting plates.

[0083] See also Figure 6 , 7 As shown, the positioning component 43 includes a positioning plate 431 and a positioning driving part 432 driving the positioning plate 431 to rotate, an upper material guide plate 433 is provided between the positioning plate 431 and the bag frame 410, the top of the upper material guide plate 433 is in contact with or connected to the bottom front side of the bag frame 410, the upper material guide plate 433 is arranged tilted forward from top to bottom, a positioning opening 434 is provided on the top front side of the positioning plate 431, and the positioning driving part 432 drives the positioning opening 434 to be arranged opposite to the upper material guide plate 433, or to make the positioning opening 434 arranged forward;

[0084] The bag guiding component 44 is arranged to tilt downward from the back to the front, and a bag guiding groove 440 penetrating the front and rear ends is provided on the top of the bag guiding component 44 , and the rear end of the bag guiding groove 440 is arranged directly below the positioning plate 431 .

[0085] In this embodiment, after the bag taking component takes out a lens packaging bag, in order to ensure that it normally falls downward to the positioning opening of the positioning plate, the upper material guide plate guides the lens packaging bag so that it falls downward and abuts against the positioning opening of the positioning plate, and then the printed label paper is pasted on the lens packaging bag by the printing and labeling mechanism, and then the positioning drive unit drives the positioning plate to rotate so that the positioning opening rotates forward and downward, releases the supporting force on the lens packaging bag, and pushes the lens packaging bag to fall downward, so that it falls into the guide bag groove, and moves forward through the inclined guide bag groove to fall into the loading mechanism for loading. The setting of the positioning component can support and limit the lens packaging bag, facilitate the label paper to be pasted, and can also make the lens packaging bag after the label paper is pasted fall downward. The middle part of the bag guide component is located directly above the first conveying mechanism, and the front end is located directly above the loading mechanism. After the positioning plate is turned over, the lens packaging bag falls downward into the guide bag groove, and slides forward into the loading mechanism through the inclined guide bag groove.

[0086] The positioning drive unit adopts a rotary cylinder or a rotary motor to drive the positioning plate to rotate.

[0087] More preferably, a lifting mechanism 435 is provided, which drives the positioning component to move up and down. When the lens packaging bag is taken out of the bag frame, the lifting mechanism drives the positioning component to move upward, so that the positioning port is arranged close to the bottom of the upper material guide plate, and the bottom of the lens packaging bag is located in the positioning port. Then the positioning mechanism drives the positioning plate to move downward, so that the lens packaging bag is facing the printing and labeling mechanism and is arranged close to the bag guide component. When the positioning plate is flipped over later, the lens packaging bag can smoothly fall into the bag guide groove and fall downward.

[0088] Printing labeling mechanism :

[0089] See also Figure 6 , 7 As shown, the printing and labeling mechanism 5 is arranged beside the bag placing mechanism 4, and the printing and labeling mechanism 5 is used to print the data measured by the lens power leak tester 3, and to stick the printed label paper on the lens packaging bag 11 released by the bag placing mechanism.

[0090] The printing and labeling mechanism comprises a printing and labeling mechanism and a labeling mechanism, and the printing mechanism prints, releases and reels the label paper.

[0091] The printing mechanism includes a printer (not shown in the printer figure), a unwinding reel 510 and a reel 512. The unwinding reel is used to release the label paper. The released label paper is printed by the printer, and then the label paper is pasted on the lens packaging bag after passing through the labeling mechanism. The release paper peeled off the label paper is then rolled up by the reel.

[0092] See also Figure 6 , 7 As shown, the labeling mechanism includes a pressing block 520 and a pushing portion 521. The pressing block 520 is rotatably arranged below the bag taking component 42 and is arranged on the front side of the positioning component 43. The pushing portion 521 includes a connecting shaft 522, a pushing wheel 523 and a second driving portion 524. The pushing wheel 523 is connected to the connecting shaft 522 via a first bracket 525. The connecting shaft 522 is arranged on the front side of the pressing block 520. The pushing wheel 523 is rotatably installed on the first bracket 525. The rear outer surface of the pushing wheel 523 abuts against the front end surface of the pressing block 520. The second driving portion 524 drives the connecting shaft 522 to rotate and pushes the bottom of the pressing block 520 to rotate backward to apply the label paper to the lens packaging bag.

[0093] In this embodiment, the pressing block is located at the front side of the upper material guide plate, the upper part of the pressing block is connected to the frame for rotation, the push wheel contacts the lower part of the front side wall of the pressing block, and when the bottom of the lens packaging bag is against the bottom surface of the positioning port, the upper part of the lens packaging bag will press the pressing block. The printed label paper will pass through the rear side of the pressing block, and when passing through the rear side of the pressing block, the label paper will be peeled off from the release paper. When the label paper needs to be pasted on the lens packaging bag, the second driving unit drives the shaft to rotate. The second driving unit adopts a rotary cylinder or a rotary motor. The bottom of the first bracket is connected to the outer surface of the shaft. The shaft rotates to drive the top of the first bracket to move backward. When the top of the first bracket moves backward, the bottom of the pressing block is pushed by the push wheel to rotate backward, and the label paper is pasted on the lens packaging bag to achieve the pasting of the label paper. After the lamination is completed, the second driving unit drives the connecting shaft to rotate in the opposite direction, driving the top of the first bracket to rotate backward, thereby releasing the backward thrust on the bottom of the pressing block. During this process, since the top of the pressing block is rotatably connected to the frame, the bottom of the pressing block will automatically rotate forward due to its own weight, breaking away from contact with the lens packaging bag. Subsequently, the positioning plate rotates to release the lens packaging bag after labeling.

[0094] Of course, the printing and labeling mechanism has another structure: the printing and labeling mechanism includes a printer and a pushing part (the printer is equivalent to the pressure block in the above method), the top of the printer is rotatably connected to the frame, the printer is rotatably arranged between the bag taking part and the bag frame part, the print head on the rear side of the bottom of the printer is located in front of the upper material guide plate, the pushing part includes a connecting shaft, a push wheel and a second driving part, the push wheel is connected to the connecting shaft via a first bracket, the connecting shaft is arranged on the front side of the printer, the push wheel is rotatably installed on the first bracket, the rear outer surface of the push wheel is against the front end surface of the printer, the second driving part drives the connecting shaft to rotate, and pushes the bottom of the printer to rotate backward, so that the print head of the printer contacts the lens packaging bag above the positioning plate, and the data measured by the lens degree measuring instrument is directly printed in the lens packaging bag.

[0095] In this method, the printer is located in front of the upper material guide plate, the upper part of the printer is connected to the frame in rotation, the push wheel contacts the lower part of the front side wall of the printer, and when the bottom of the lens packaging bag abuts against the bottom surface of the positioning port, the upper part of the lens packaging bag will be aligned with the printer's print head. When the lens packaging bag abuts against the positioning port, the lens packaging bag faces the printer, and then the second driving unit drives the shaft to rotate. The second driving unit adopts a rotary cylinder or a rotary motor. The bottom of the bracket is connected to the outer surface of the shaft. The shaft rotates, driving the top of the bracket to move backward. When the top of the bracket moves backward, the push wheel pushes the bottom of the printer to rotate backward, and the printer's print head contacts the front side wall of the lens packaging bag, and the detection information is directly printed on the lens packaging bag. After printing is completed, the second driving unit drives the coupling to rotate in the opposite direction, driving the top of the bracket to rotate backward, thereby releasing the backward thrust on the bottom of the printer. During this process, since the top of the printer is connected to the frame for rotation, the weight of the printer will cause the bottom of the pressing block to automatically rotate forward and be perpendicular to the horizontal plane, breaking away from contact with the lens packaging bag. Subsequently, the positioning plate rotates to release the lens packaging bag with printed detection information.

[0096] A photoelectric sensor may be provided to detect whether there is a lens packaging bag on the positioning port of the positioning plate, so as to ensure that the lens packaging bag can be labeled or printed normally.

[0097] Film loading mechanism:

[0098] See also Figure 1 , 2 As shown in FIGS. 5, 8 and 9, the lens loading mechanism 6 is arranged opposite to the bag placing mechanism 4, and the lens loading mechanism 3 is used to load the lenses after the degree detection into the lens packaging bag 11 covered with label paper.

[0099] The film loading mechanism 6 includes a bag opening mechanism 61, a lens supporting mechanism 62 and a film pushing mechanism 63. The lens supporting mechanism 62 is arranged at the end of the lens conveying mechanism 2. The lens supporting mechanism 62 is used to lift the lens on the lens conveying mechanism 2 and detach it from the top surface of the lens conveying mechanism 2.

[0100] The sheet pushing mechanism 63 and the bag opening mechanism 61 are respectively arranged at the front side and the rear side of the end of the lens conveying mechanism 2, and the sheet pushing mechanism 63 and the bag opening mechanism 61 are respectively arranged at the front side and the rear side of the lens supporting mechanism 62;

[0101] The front end of the bag opening mechanism 61 is arranged directly below the front end of the bag placing mechanism 4, the lens packaging bag released by the bag placing mechanism is released on the bag opening mechanism, and the bag opening mechanism opens the opening of the lens packaging bag;

[0102] The lens pushing mechanism pushes the lens on the lens supporting mechanism into the lens packaging bag.

[0103] In this embodiment, the end of the lens conveying mechanism is located at the right end of the first conveying mechanism, and the lens supporting mechanism is located inside the right end of the first conveying mechanism. Under normal circumstances, when the lens is conveyed to the supporting mechanism, the supporting mechanism pushes the lens on the first conveying mechanism upward to make it separate from the first conveying mechanism. At this time, the bag opening mechanism has released the lens packaging bag with lens detection information released by the bag placing mechanism onto the bag opening mechanism, and then the bag opening mechanism opens the opening at the rear end of the lens packaging bag, which is facing the lens, and then the lens pushing mechanism pushes the lens on the supporting mechanism forward into the lens guarantee bag, so that the lens packaging can be realized.

[0104] See also Figure 5 As shown, the lens support mechanism 62 includes a support block 620 and a support driving member 621, and the support driving member 621 drives the support block 620 to rise and fall; when the support block 620 rises, the top plane of the support block 620 is arranged above the top plane of the first conveyor belt 210, and when the support block 620 moves downward, the top plane of the support block 620 is arranged below the top plane of the first conveyor belt 210;

[0105] Among them, the lens support mechanism is located directly below the bag guide component, the support block is located inside the right end of the first conveying mechanism, and the support driving component adopts a support cylinder. When the output shaft of the support cylinder retracts, the top surface of the support block will be below the top surface of the first conveyor belt. At this time, the first conveyor belt can normally convey the lens to the right. A photoelectric sensor will be set to detect whether there is a lens there. If there is a lens, the support driving component will lift the support block so that the support block lifts the lens on the first conveyor belt above it and separates it from the first conveyor belt. At this time, the support block can also block the lens on the left to prevent the lens from moving to the right. After the lens is lifted up, the film pushing mechanism will push the lens on the support block forward and enter the lens packaging bag to realize the packaging of the lens.

[0106] See also Figure 5 As shown, the lens pushing mechanism 63 includes a pushing block 631 and a pushing block driving member 632. The pushing block driving member 632 is installed at the rear side of the lens conveying mechanism 2. The rear end of the pushing block 631 is connected to the pushing block driving member 632. The pushing block driving member 631 drives the pushing block 631 to move forward and backward and push the lens on the supporting block 620 into the lens packaging bag.

[0107] The front end of the push block 631 is provided with a push opening 633 , which is a V-shaped push opening.

[0108] The push block driving member is a cylinder, which drives the push block to move forward, pushing the lens on the support block into the lens packaging bag to realize the packaging of the lens. In order to ensure that the lens moves forward stably into the lens packaging bag when being pushed away from the support block, a push opening is provided at the front end of the push block, and the push opening is V-shaped, so that the lens moves forward stably and accurately into the lens packaging bag.

[0109] See also Figure 8 , 9 As shown, the bag opening mechanism 61 includes a material bin 610, a bag clamping component 611, a bag blocking component 612 and a bag opening component 613. The top of the material bin 610 has a film loading cavity 6101 penetrating from the front and rear ends. The bottom of the film loading cavity 6101 is arranged to be inclined downward from the back to the front.

[0110] The bag blocking component 612 is disposed at the front end of the film loading cavity 6101 .

[0111] The bag clamping component 611 includes two clamping blocks 6110 arranged opposite to each other and a clamping block driving unit 6111 driving the two clamping blocks 6110 to move closer to or farther away from each other. The two clamping blocks 6110 are respectively arranged on the left and right sides of the symmetrical material bin 610, and the clamping blocks 6110 are arranged on the rear side of the bag blocking component 612 and close to the bag blocking component 612. The clamping block driving unit 6111 drives the inner end of the clamping block 6110 to move into the film loading cavity 6101 or away from the film loading cavity 6101.

[0112] The bag opening component 613 is arranged near the rear end of the material bin 610, and is provided with an upper bag opening suction cup 6130, a lower bag opening suction cup 6131 and a bag opening drive unit. The upper bag opening suction cup 6130 is arranged above the material bin 610, and the lower bag opening suction cup 6131 is arranged below the material bin 610. The bag opening drive unit drives the upper bag opening suction cup and the lower bag opening suction cup to approach each other and enter into the loading cavity, or to move away from each other and leave the loading cavity.

[0113] The bag blocking component 612 includes a baffle 6120 and a baffle driving unit 6121. The top of the baffle 6120 is rotatably connected to the rear end of the loading chamber 6101. The baffle driving unit 6121 drives the baffle 6120 to rotate, so that the baffle 6120 closes or opens the front end of the loading chamber 6101. The baffle driving unit adopts a rotating cylinder or a rotating motor, which drives the baffle to rotate.

[0114] The clamp block driving part is installed at the bottom of the silo, and the two ends of the clamp block driving part are respectively connected to the bottoms of the two clamp blocks; the clamp block driving part is a clamp block cylinder, and the left and right ends of the clamp block cylinder are respectively provided with output shafts, and the output shafts at both ends are respectively connected to the two clamp blocks, and the clamp block cylinder can simultaneously drive the two clamp blocks to move closer to or away from each other.

[0115] The bag opening drive unit includes an upper bag opening cylinder 6132 and a lower bag opening cylinder 6133. The upper bag opening cylinder 6132 is arranged directly above the material bin 610, and drives the upper bag opening suction cup to move downward and close to the bottom surface of the loading cavity, or move upward above the loading cavity; the lower bag opening cylinder 6133 is arranged below the material bin, and a through hole connected to the loading cavity is provided at the bottom of the material bin, and the lower bag opening suction cup is arranged directly opposite to the through hole, and drives the lower bag opening suction cup to move upward through the through hole into the loading cavity, or move downward to below the through hole.

[0116] Before opening the bag, the bag guiding component sends the lens packaging bag into the film loading cavity of the silo. At this time, the bottom of the baffle is arranged close to the bottom surface of the film loading cavity. After the lens packaging bag enters the film loading cavity, its front end will be blocked by the baffle. Then the clamping block driving part drives the two clamping blocks to move inward, enter the film loading cavity, and are located on both sides of the front end of the lens packaging bag. Then the output shafts of the upper bag opening cylinder and the lower bag opening cylinder extend out, driving the upper bag opening suction cup to press against the top of the rear end of the lens packaging bag and the lower bag opening suction cup to press against the bottom of the rear end of the lens packaging bag, and suck the lens packaging bag. Then the output shafts of the upper bag opening cylinder and the lower bag opening cylinder retract, so that the upper bag opening suction cup and the lower bag opening suction cup open the opening at the rear end of the lens packaging bag (in this process, the clamping block can limit the front end of the lens packaging bag, so that the rear end of the lens packaging bag can be opened normally); the film pushing mechanism pushes the lens forward and enters the lens packaging bag. After the film loading is completed, the upper and lower bag opening suction cups release the adsorption of the lens packaging bag (the clamping block of the bag clamping component moves away from the silo, releasing the limit on the lens packaging bag), and then the baffle driving unit drives the bottom of the baffle to rotate forward to open the front end of the film loading chamber. Since the bottom surface of the film loading chamber is tilted downward from the back to the front, the lens packaging bag will automatically move forward and fall from the silo, and then the baffle is reversed to close the front end of the loading chamber and wait for the next lens to be packaged. Among them, a through groove is set at the bottom of the silo, and the through groove is on the rear side of the baffle. A photoelectric sensor is installed at the bottom of the silo below the through groove, which can detect whether there is a lens packaging bag in the film loading chamber, thereby controlling the normal bag opening action and other actions.

[0117] See also Figure 5 , 8As shown in FIG. 9 , the bag opening mechanism 61 is rotatably arranged at the front side of the lens conveying mechanism 2, and a bag opening mechanism driving member 64 is also provided. The bag opening mechanism driving member 64 drives the bag opening mechanism 61 to rotate, so that the front end of the bag opening mechanism 61 swings up and down.

[0118] In this embodiment, the lower rear end of the silo is rotatably connected to the frame, the bag opening mechanism driving component adopts a cylinder, the rear end of the bag opening driving component is rotatably connected to the frame, and the front end output shaft is rotatably connected to the front end side of the silo. When the output shaft of the bag opening driving component is retracted, the rear end of the film loading cavity will face the upward moving support block, so that the lens can smoothly enter the lens packaging bag. At this time, the inclination angle between the bottom surface of the film loading cavity and the horizontal plane is relatively small, and at this time, there is a certain angle between the bottom surface of the film loading cavity and the bottom surface of the bag guiding groove. When the lens packaging bag dropped from the bag guiding groove falls into the film loading cavity, it will get stuck. Therefore, after the loading is completed, the output shaft of the bag opening mechanism driving component extends to push the front end of the material bin to rotate downward, so that the angle between the material bin and the horizontal plane becomes larger and the bottom surface of the film loading cavity and the bottom surface of the bag guiding groove are arranged on the same plane, so that the lens packaging bag containing the lens can quickly fall out of the film loading cavity, and the lens packaging bag in the bag guiding cavity can also smoothly fall into the film loading cavity. After the lens packaging bag is loaded into the film loading cavity, the output shaft of the bag opening mechanism driving component retracts, driving the front end of the material bin to rotate upward, so that the film loading cavity is directly opposite to the lens lifted by the support block.

[0121] A pushing mechanism is provided at the rear side of the finished product bin, and the pushing mechanism is arranged directly below the film loading mechanism;

[0122] The pushing mechanism includes a push plate 72 and a push plate driving part 73 . The push plate driving part is connected to the push plate and drives the push plate to be close to the blocking plate or away from the blocking plate.

[0123] The push plate driving part is a cylinder. The blocking plate is directly placed in the finished product warehouse by its own weight and is slidably connected to the finished product warehouse. After the lens packaging bag loaded with lenses in the loading mechanism falls, it will directly fall between the push plate and the blocking plate. The push plate and the blocking plate are limited so that the lens packaging bag is basically perpendicular to the horizontal plane, so that more lens packaging bags can be placed in the finished product warehouse. After a lens packaging bag enters the finished product warehouse, the push plate driving part drives the push plate to move forward by the thickness of the lens packaging bag loaded with lenses, so that the lens packaging bag in the loading mechanism can fall between the lens packaging bag at the rear of the finished product warehouse and the push plate, so that the lens packaging bags can be sorted from back to front, which is convenient for the operator to take away the sorted products in the finished product warehouse later.
