[0046] The Y-direction linear module 201 is fixedly arranged on the lower workbench 54 along the Y direction. A support frame 202 is installed on the Y-direction linear module 201. The support frame 202 is fixed to the movable part of the Y-direction linear module 201, enabling it to move back and forth along the Y direction under the drive of the motor of the Y-direction linear module 201. The rotary cylinder 203 is fixedly installed on the outer side of the support frame 202 through screws. The flipping frame 204 is connected to the inner side of the support frame 202 through bearings. The output shaft of the rotary cylinder 203 is key-connected to the flipping frame 204;

[0047] A plurality of pairs of fixed rods 207 are fixed to the front surface of the flipping frame 204. A clamping cylinder 205 is fixedly installed on the back surface of the flipping frame 204 through screws. The output end of the clamping cylinder 205 is fixedly provided with a clamping rod frame 206 through screws. A plurality of pairs of clamping rods 208 are fixed to the front surface of the clamping rod frame 206. The two clamping rods 208 in each pair are symmetric with respect to the vertical plane of the plane formed by the axis connection line of its corresponding pair of fixed rods 207. Further, the distance between a pair of clamping rods 208 is less than the distance between its corresponding pair of fixed rods 207.

[0048] During feeding, the lens mold 301 is placed at the front end of the feeding table 101. The rotary motor drives the synchronous pulley 102 to rotate, thereby driving the synchronous belt 103 to rotate, and then driving the lens mold 301 to move from front to back along the Y direction;

[0049] The X-direction cylinder 105 drives the Z-direction cylinder 106 to move along the X direction, so that the negative pressure nozzle support 107 reaches above the lens mold 301. The Z-direction cylinder 106 drives the negative pressure nozzle support 107 to move downward along the Z direction, so that the suction cup 109 at the lower end of the negative pressure nozzle 108 contacts the lens mold 301. The negative pressure pump a provides negative pressure, so that the suction cup 109 sucks the lens mold 301. The Z-direction cylinder 106 drives the negative pressure nozzle support 107 to move upward along the Z direction, and lifts the lens mold 301;

[0050] The support frame 202 reaches the corresponding position under the drive of the motor in the Y-direction linear module 201. The rotary cylinder 203 drives the turnover frame 204 to turn to the horizontal, and the front side of the turnover frame 204 faces upward. The X-direction cylinder 105 drives the Z-direction cylinder 106 to move along the X-direction towards the turnover fastening mechanism 2, so that the negative pressure nozzle bracket 107 moves towards the turnover fastening mechanism 2 until each lens mold 301 corresponds to be between a corresponding pair of fixed rods 207 and a pair of clamping rods 208. The Z-direction cylinder 106 drives the negative pressure nozzle bracket 107 to move downward along the Z-direction, so that the lens mold 301 contacts the turnover frame 204, and then the negative pressure is released, and the lens mold 301 is separated from the suction cup 109, and the mold is transferred to the turnover frame 204. Driven by the X-direction cylinder 105 and the Z-direction cylinder 106, the negative pressure nozzle bracket 107 moves upward and along the X-direction, away from the turnover fastening mechanism 2;

[0051] Then the clamping cylinder 205 drives the clamping rod frame 206 to move along the X-direction, and the clamping rod 208 approaches the fixed rod 207 along the clamping rod guide groove 209, so that the clamping rod 208 and the fixed rod 207 clamp the lens mold 301 therebetween. After the lens mold 301 is clamped, the rotary cylinder 203 drives the turnover frame 204 to turn to the vertical, and then it can enter the filling process for processing.

[0052] Refer to Figure 5 , the perfusion assembly 3 includes an X-axis traveling mechanism 302 arranged along the X-axis direction at the topmost part of the fuselage 5 and a deviation rectifying perfusion mechanism 303 located between the turnover fastening mechanism 2 and the X-axis traveling mechanism 302;

[0053] See Figure 6 , the X-axis traveling mechanism 302 includes an X-axis servo slide rail 3021 arranged along the X-axis direction.

It also includes two X-axis auxiliary positioning slide rails 3023 arranged in parallel on both sides of the X-axis servo slide rail 3021, which are used to ensure the directional operation of the lower-suspended deviation rectifying perfusion mechanism 303. A suspension module 3024 is also slidably connected to the surfaces of the X-axis servo motor 3022 and the X-axis auxiliary positioning slide rail 3023, which is used to suspend and fix the deviation rectifying perfusion mechanism 303;

[0054] See Figure 7, the deviation correction perfusion mechanism 303 includes a hanging bracket 3031 connected to the hanging module 3024.

[0055] See Figure 8 , the Z-axis displacement installation mechanism 3032 includes a rectangular mounting plate 3032a. On the surface of the mounting plate 3032a, two parallel Z-axis slide rails 3032b are installed along the Z-axis direction. A Z-axis lead screw 3032c is also arranged between the two Z-axis slide rails 3032b. The top of the Z-axis lead screw 3032c is installed with a driving lead screw motor 3032d. A lead screw transmission block 3032e and a Z-axis slider 3032f in the same horizontal plane are respectively sleeved on the surfaces of the Z-axis lead screw 3032c and the Z-axis slide rail 3032b;

[0056] See Figure 9 and Figure 10 , the lead screw transmission block 3032e and the Z-axis slider 3032f in the same horizontal plane are both fixedly connected to the lifting mounting plate 304, so that the lifting mounting plate 304 is arranged along the Y-axis direction and can move up and down along the Z-axis direction. A hot-melt displacement cylinder 305 is installed on the front of the lifting mounting plate 304. The bottom end of the hot-melt displacement cylinder 305 is connected to a hot-melt transmission module 306. The front of the hot-melt transmission module 306 is connected to a plurality of hot-melt perforation needles 307. A perfusion displacement motor 308 is also installed on the top of the lifting mounting plate 304. The bottom end of the perfusion displacement motor 308 is connected to a displacement lead screw 309. The bottom of the displacement lead screw 309 is drivingly connected to a perfusion mounting block 310. The front of the perfusion mounting block 310 is connected to 4 perfusion needle modules 312 through 4 perfusion connecting rods 311. 4 fine-tuning deviation correction motors 313 are also fixedly installed on the bottom surface of the lifting mounting plate 304. The output end of each fine-tuning deviation correction motor 313 is drivingly connected to a perfusion negative pressure defoaming positioning module 314;

[0057] At the top of each perfusion negative pressure bubble removal and positioning module 314, a limit slide rail 315 arranged along the Z-axis direction is clamped through a card slot. A perfusion slide rail 316 is provided on the front surface of the limit slide rail 315. The perfusion slide rail 316 and the perfusion needle module 312 are slidably sleeved to achieve the up and down displacement of the perfusion needle module 312. A hot melt slide rail 317 is provided on the side surface of the limit slide rail 315. The hot melt slide rail 317 and the side surface of the hot melt drive module 306 are slidably sleeved to achieve the up and down displacement of the hot melt perforation needle head 307;

[0058] See Figure 11 , the bottom surface of the perfusion negative pressure bubble removal and positioning module 314 is an arc surface, which matches the arc of the outer edge of the lens mold 301. A circular perfusion needle limit hole 318 and a plurality of negative pressure air extraction and bubble removal holes 319 arranged around the perfusion needle limit hole 318 are also provided on the arc bottom surface of the perfusion negative pressure bubble removal and positioning module 314, which are used to suck out and exhaust the bubbles generated during the mold perfusion process under negative pressure.

[0059] After the lens mold 301 is loaded and turned to a vertical position, the X-axis walking mechanism 302 drives the correction and perfusion mechanism 303 to move along the X-axis servo slide rail 3021, and at the same time, the Y-axis linear module 201 drives the lens mold 301 to move along the Y direction until the high-definition camera 3033a on the camera adjustment mechanism 3033 is aligned with the lens mold 301. At this time, the lens mold 301 does not move anymore. Since the distance between the high-definition camera 3033a and the hot melt perforation mechanism 3034 is fixed, the entire correction and perfusion mechanism 303 is driven forward by the X-axis walking mechanism 302 for a certain distance. , so that the hot melt perforating mechanism 3034 is located directly above the lens mold 301. At this time, the hot melt displacement cylinder 305 drives the hot melt perforating needle 307 to move downward through the hot melt transmission module 306, and the hot melt pierces the packaging tape at the top of the lens mold 301 to form a circular perfusion hole. After the hot melt puncture is completed, the hot melt displacement cylinder 305 drives the hot melt perforating needle 307 to move upward and reset. After the melt displacement cylinder 35 is reset, the X-axis walking mechanism 302 continues to drive the entire deviation correction perfusion mechanism 303 to move forward a certain distance, so that the perfusion of the bottom surface of the negative pressure degassing positioning module 314 is The needle limiting hole 318 is aligned with the circular perfusion hole, and the fine-tuning correction motor 313 drives the perfusion negative pressure bubble removal positioning module 314 and the perfusion needle module 312 connected to its top groove to perform fine-tuning on the overall displacement to adapt to the problem of deviation in the position of the circular perfusion hole caused by different thicknesses of lenses with different diopters. After the fine-tuning is completed, the displacement screw 309 connected to its bottom end is driven to rotate by the perfusion displacement motor 308, and the displacement screw 309 rotates to transmit the displacement power to the perfusion mounting block 310 connected to its bottom transmission, so that the perfusion mounting block 310 moves downward as a whole, and the perfusion mounting block 310 is also moved downward. The four infusion needle modules 312 connected at the front end by four infusion connecting rods 311 also move downward together and spread into the lens mold 301 from the infusion needle limit holes 318 to infuse the lens raw materials. The infusion needle modules 312 move upward and reset while infusing. At the same time, negative pressure vacuuming is performed through the negative pressure vacuuming holes 319 set on the bottom surface of the infusion negative pressure debubble positioning module 314, thereby expelling bubbles that may be generated during the infusion process and reducing the defective rate of lens preparation. After the infusion is completed, the clamping mechanism drives the lens mold 301 that has been infused to move into the gluing and sealing process for further processing.

[0064] The guide wheel assembly includes a first guide wheel 441 and a second guide wheel 442. Both the first guide wheel 441 and the second guide wheel 442 are connected to the front of the component frame 422 through bearings. The tensioning wheel 432 is located above the first guide wheel 441 and the second guide wheel 442.

[0065] Refer to Figure 16 , the first-stage pressing assembly includes a first-stage pressing cylinder 451, a first-stage pressing wheel bracket assembly 452, and a first-stage pressing wheel 453. The first-stage pressing cylinder 451 is vertically and downwardly fixedly installed on the component frame 422. The first-stage pressing wheel bracket assembly 452 is fixed to the lower end of the output shaft of the first-stage pressing cylinder 451. The first-stage pressing wheel 453 is rotatably connected to the lower end of the first-stage pressing wheel bracket assembly 452. The first-stage pressing cylinder 451 can drive the first-stage pressing wheel 453 to move up and down along the X direction.

[0066] The second-stage pressing assembly includes a second-stage pressing cylinder 461, a second-stage pressing wheel bracket assembly 462, and a second-stage pressing wheel 463. The second-stage pressing cylinder 461 is vertically and downwardly fixedly installed on the component frame 422 along the Z direction. The second-stage pressing wheel bracket assembly 462 is fixed to the lower end of the output shaft of the second-stage pressing cylinder 461. The second-stage pressing wheel 463 is rotatably connected to the lower end of the second-stage pressing wheel bracket assembly 462. The second-stage pressing cylinder 461 can drive the second-stage pressing wheel 463 to move up and down along the Z direction.

[0067] The first-level pressing wheel frame assembly 452 includes a movable bracket 4521, two connecting rods 4522, two springs 4523, and a wheel frame 4524. The movable bracket 4521 is fixedly arranged at the lower end of the output shaft of the first-level pressing cylinder 451. The two connecting rods 4522 are vertically fixed on the movable bracket 4521. Each connecting rod 4522 is connected to the wheel frame 4524 through a spring 4523. The first-level pressing wheel 453 is connected to the wheel frame 4524 through a bearing. When the first-level pressing cylinder 451 drives the first-level pressing wheel 453 to press the tape on the mold, the spring 4523 is compressed, playing a buffering role to prevent the first-level pressing wheel 453 from directly colliding with the mold and being damaged.

[0068] The structures and dimensions of the first-level pressing wheel frame assembly 452 and the second-level pressing wheel frame assembly 462 are the same. The strokes of the first-level pressing cylinder 451 and the second-level pressing cylinder 461 are the same. The height of the second-level pressing cylinder 461 is lower than that of the first-level pressing cylinder 451. After the tape is cut, the second-level pressing wheel frame assembly 462 can further press the tape. To prevent the tape from twisting, the axes of the tensioning wheel 432, the first guiding wheel 441, the second guiding wheel 442, the first-level pressing wheel 453, and the second-level pressing wheel 463 are all parallel.

[0069] Refer to Figure 14 and Figure 15 As shown in, the negative pressure assembly 47 includes a negative pressure guiding frame 471 and a guiding frame bottom plate 472. The negative pressure guiding frame 471 is fixedly arranged on the assembly frame 422. The guiding frame bottom plate 472 is fixedly arranged on the lower side of the negative pressure guiding frame 471. A tape groove 473 penetrating through the front and back is formed on the negative pressure guiding frame 471. A negative pressure chamber is arranged inside the negative pressure guiding frame 471. A plurality of air vent holes 474 communicating with the negative pressure chamber are formed on the lower side of the negative pressure guiding frame 471. A suction port 475 communicating with the negative pressure chamber is formed on the upper side of the negative pressure guiding frame 471. The suction port 475 is connected to the negative pressure pump b through a connecting hose. After the negative pressure pump b is started, a negative pressure is formed in the negative pressure chamber to adsorb the tape passing through the tape groove 473, making its upper side fit with the negative pressure guiding frame 471 to prevent the glue-coated surface on the lower side of the tape from sticking to the guiding frame bottom plate 472.

[0070] Furthermore, the plane where the lower edge of the air vent hole 474 is located coincides with the tangent plane of the first guiding wheel 441 and the second guiding wheel 442, making the running of the tape smoother.

[0071] The cutting assembly includes a cutting cylinder frame 481, a cutting cylinder 482, a pressing block 483, a bracket 484, and spring scissors 485. The cutting cylinder frame 481 is fixed to the back of the assembly frame 422 and is perpendicular to it. The output end of the cutting cylinder 482 is installed downward on the cutting cylinder frame 481 and is parallel to it. The lower end of the output shaft of the cutting cylinder 482 is fixedly provided with the pressing block 483. The lower end of the cutting cylinder frame 481 is fixedly provided with the bracket 484. The spring scissors 485 are placed on the bracket 484, and the cutting edge of the spring scissors 485 extends between the first pressing wheel 453 and the second pressing wheel 463.

[0072] The tape roll is placed on the tensioning wheel 432 with the glue-coated surface facing downwards. It passes through the negative pressure guiding frame 471 from below the first guiding wheel 441 and the second guiding wheel 442, and then passes through the middle of the two cutting edges of the spring scissors 485 from below the first pressing wheel 453 and the second pressing wheel 463.

[0073] After the lens mold 301 filled with liquid is moved backward from front to back under the action of the Y-direction linear module 201, when it moves to the lower side of the first pressing assembly, the first pressing cylinder 451 drives the first pressing wheel frame assembly 452 to press down, so that the first pressing wheel 453 pastes the tape at the opening on the mold. Then, the cutting cylinder 482 drives the pressing block 483 to move downward, and the pressing block 483 and the bracket 484 squeeze the spring scissors 485 to make its two cutting edges close, and the spring scissors 485 cut the tape. Then the mold continues to move backward, and the second pressing cylinder 461 drives the second pressing wheel frame assembly 462 to press down, so that the second pressing wheel 463 presses the tape firmly.

[0074] The structure of the blanking mechanism 6 is the same as that of the feeding mechanism 1. It is arranged along the Y direction at the rear side of the feeding mechanism 1. After the lens mold 301 is pasted and sealed, the support frame 202 reaches the corresponding position under the drive of the motor in the Y-direction linear module 201, and the rotary cylinder 203 drives the flipping frame 204 to flip to the horizontal position, with the front side of the flipping frame 204 facing upward. The blanking mechanism 6 sucks and places the lens mold 301 on the blanking table for blanking.

[0075] Embodiment 2: Refer to Figure 17 , which is different from Embodiment 1 in that the cutting assembly includes a cutting cylinder frame 481, a cutting cylinder 482, a hot melt wire frame 486, and a hot melt wire 487; the cutting cylinder frame 481 is fixed to the back of the assembly frame 422 and is perpendicular to it. The output end of the cutting cylinder 482 is installed downward on the cutting cylinder frame 481 and is parallel to it. The lower end of the output shaft of the cutting cylinder 482 is fixedly provided with the hot melt wire frame 486, and the hot melt wire 487 is fixedly arranged on the hot melt wire frame 486. The hot melt wire 487 extends between the first pressing wheel 453 and the second pressing wheel 463.

[0076] After the tape is attached to the opening of the mold, the cutting cylinder 482 drives the hot melt wire frame 486 to move downward. The hot melt wire 487 moves downward to contact the tape, thermally melts and cuts the tape, and then the secondary pressing assembly presses the tape tightly against the mold.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
