The inner wall annular array of the turntable body 221 is fixedly connected to a slide rod 222. The inner bottom of the plurality of slide rods 222 is fixedly connected to a middle turntable 223. The bottom of the middle turntable 223 is rotatably connected to the top of the middle part of the chassis 211, and the top annular array of the turntable body 221 is fixedly connected to the arc plate 224. The lens placement mechanism 4 includes a motor placement component connection block 41, and the top of the motor placement component connection block 41 is fixedly connected to a cross plate 42. The top four sides of the cross plate 42 are respectively provided with cross plate slide grooves 43. The middle part of the inner wall of the cross plate 42 is rotatably connected to a screw rod 44. The bottom end of the screw rod 44 extends to the bottom of the outer wall of the motor placement component connection block 41 and is fixedly connected to a gear 45. The top of the screw rod 44 is rotatably connected to a top plate 46. The top annular array of the top plate 46 is provided with a top plate slide groove 47 that runs through to the bottom.

[0037] When it is necessary to cut the optical lens, the motor 218 is started. After the motor 218 is started, the transmission rotating rod 219 rotates. When the rotating rod 219 rotates, it drives the rotating rod 2110 to rotate synchronously. When the rotating rod 2110 rotates, it drives the rotating block 2111 and the fan-shaped rotating plate 2112 to rotate synchronously. When the rotating block 2111 rotates, it rotates into the inner wall of one of the slide groove rods 222 fixed on the inner wall of the turntable body 221, thereby driving the turntable body 221 to rotate as a whole. When the fan-shaped rotating plate 2112 rotates to align with one of the arc plates 224, the turntable body 221 stops rotating. The rotation of the turntable body 221 drives multiple lens placement mechanisms 4 on the outer wall to rotate, and one of the lens placement mechanisms 4 rotates to the lens discharge. When the front bottom of the mechanism 3 is reached, the lens discharging mechanism 3 discharges the optical lens to the top of the top plate 46. At the same time, the turntable body 221 continues to rotate through the abutment of the rotating block 2111. When the turntable body 221 drives the lens placing mechanism 4 to rotate to one side of the multiple second tooth blocks 2114 fixed on the outer wall of the slide groove plate 212, the gear 45 fixed at the bottom end of the screw rod 44 meshes with the multiple second tooth blocks 2114, thereby driving the screw rod 44 to rotate in the middle of the inner wall of the cross plate 42. The meshing columnar transmission rod 48 of the screw rod 44 rotates axially upward on the inner wall of the screw rod 44 on the outer wall of the screw rod. While the columnar transmission rod 48 moves axially upward, it drives multiple rotating rod connecting rods 49 to move upward synchronously. When the rod 49 moves upward, it drives the multiple rotating rods 410 to rotate synchronously. When the multiple rotating rods 410 rotate, it drives the multiple expansion plates 411 to shrink synchronously, thereby fixing the optical lens. At this time, the lens placement mechanism 4 is on the left side of the L-shaped laser cutting head connecting rod 215. At this time, the laser cutting head 2113 is started. After the laser cutting head 2113 is started, the optical lens is cut. After the cutting is completed, the turntable body 221 continues to rotate. When the turntable body 221 drives the lens placement mechanism 4 to rotate to the side of the arc-shaped tooth block connecting plate 213 fixed on the outer wall of the slide groove plate 212, the gear 45 is engaged with the multiple tooth blocks 214 fixed on one side of the arc-shaped tooth block connecting plate 213, thereby driving the screw rod 44 to rotate on the inner wall of the cross plate 42. The middle part rotates in the opposite direction, and the screw rod 44 rotates in the opposite direction, while driving the columnar transmission rod 48 to move axially downward on the outer wall of the screw rod 44, and the columnar transmission rod 48 moves axially downward while driving multiple rotating rod connecting rods 49 to move downward synchronously, and the multiple rotating rod connecting rods 49 move downward while driving multiple rotating rods 410 to rotate synchronously, and the multiple rotating rods 410 rotate while driving multiple expansion plates 411 to expand synchronously, thereby releasing the limit of the optical lens after cutting is completed. At this time, the staff can take out the cut optical lens, and so on and so forth, thereby realizing the purpose of automatic cutting of the optical lens, which not only improves the cutting efficiency of the optical lens, but also reduces the tediousness of manual operation and reduces labor costs.

[0038] like Figure 9-10 As shown, the lens discharging mechanism 3 includes a vertical plate 31, the front top of the vertical plate 31 is fixedly connected to an L-shaped connecting plate 32, the left and right sides of the front top of the L-shaped connecting plate 32 are respectively fixedly connected to the discharging mechanism sliding groove rods 33, the tops of the two discharging mechanism sliding groove rods 33 are fixedly connected to vertical rods 36, the tops and bottoms of the inner sides of the two vertical rods 36 are respectively fixedly connected to lens placement tube connection plates 37, the inner walls of the two lens placement tube connection plates 37 are fixedly connected to lens placement plates 38, and the top of the vertical plate 31 is fixedly connected to a hydraulic push rod 36. Rod connecting plate 34, the top of hydraulic push rod connecting plate 34 is fixedly connected with hydraulic push rod 35, the inner side of two discharging mechanism slide slot rods 33 is rotatably connected with push-pull plate 39, the top rear side of push-pull plate 39 is fixedly connected with push block 312, the rear side of push block 312 is fixedly connected to the front side of hydraulic push rod 35, the front side of the inner wall of push-pull plate 39 is fixedly connected with lens unloading tube 310, the bottom of lens unloading tube 310 is rotatably connected with unloading tube bottom cover 311, the top of lens unloading tube 310 is aligned with the bottom of lens placement plate 38;

[0039] When the lens placement mechanism 4 rotates to the front bottom of the lens discharge mechanism 3, the hydraulic push rod 35 is started, pushing the push block 312 to move forward, and the push block 312 drives the push-pull plate 39 to slide forward on the inner side of the two discharge mechanism slide slot rods 33. While the push-pull plate 39 slides forward, it blocks the bottom end of the lens placement plate 38 through the top rear side of the push-pull plate 39 to prevent the optical lenses stored in the lens placement plate 38 from falling out. When the lens discharge tube 310 is aligned with the top of the lens placement mechanism 4, the discharge tube bottom cover 311 is automatically turned open without the obstruction of the front bottom of the L-shaped connecting plate 32, and then the lens is discharged along the As the lens feeding tube 310 falls, after the falling is completed, the vertical rod 36 pulls the push block 312 to drive the push-pull plate 39 to move backward, and then the lens feeding tube 310 is realigned with the bottom of the lens placement plate 38. In this process, when the push-pull plate 39 slides backward, its top rear side no longer blocks the bottom end of the lens placement plate 38, and then the next optical lens to be fed falls into the inner wall of the lens feeding tube 310. At this time, the lens placement mechanism 4 can continue to rotate to move the next batch of optical lenses to the front bottom of the lens discharging mechanism 3, preparing for the next feeding operation, thereby realizing automated feeding and improving production efficiency.

[0040] Working principle of the present invention: when it is necessary to cut the optical lens, at this time, the motor 218 is started, and the motor 218 is started to drive the rotating rod 219 to rotate, and the rotating rod 219 rotates while driving the rotating rod 2110 to rotate synchronously, and the rotating rod 2110 rotates while driving the rotating block 2111 and the fan-shaped rotating plate 2112 to rotate synchronously, when the rotating block 2111 rotates, it rotates into the inner wall of one of the slide groove rods 222 fixed on the inner wall of the turntable body 221, thereby driving the turntable body 221 to rotate as a whole, and when the fan-shaped rotating plate 2112 rotates to align with one of the arc plates 224, the turntable body 221 stops rotating, and the turntable body 221 rotates to drive multiple lenses on the outer wall to be released. The lens placement mechanism 4 rotates, and when one of the lens placement mechanisms 4 rotates to the front bottom of the lens discharge mechanism 3, the lens discharge mechanism 3 discharges the optical lens to the top of the top plate 46. At the same time, the turntable body 221 continues to rotate through the abutment of the rotating block 2111. When the turntable body 221 drives the lens placement mechanism 4 to rotate to one side of the multiple second tooth blocks 2114 fixed on the outer wall of the slide groove plate 212, the gear 45 fixed at the bottom end of the screw rod 44 meshes with the multiple second tooth blocks 2114, thereby driving the screw rod 44 to rotate in the middle of the inner wall of the cross plate 42. The meshing columnar transmission rod 48 of the screw rod 44 rotates upward on the inner wall of the screw rod 44 on the outer wall of the screw rod. The columnar transmission rod 48 moves axially upward, while driving the multiple rotating rod connecting rods 49 to move upward synchronously. The multiple rotating rod connecting rods 49 move upward, while driving the multiple rotating rods 410 to rotate synchronously. The multiple rotating rods 410 rotate while driving the multiple expansion plates 411 to shrink synchronously, thereby fixing the optical lens. At this time, the lens placement mechanism 4 is on the left side of the L-shaped laser cutting head connecting rod 215. At this time, the laser cutting head 2113 is started. After the laser cutting head 2113 is started, the optical lens is cut. After the cutting is completed, the turntable body 221 continues to rotate. When the turntable body 221 drives the lens placement mechanism 4 to rotate to the outer wall of the slide groove plate 212, When the arc-shaped tooth block connecting plate 213 is fixed, the gear 45 meshes with the multiple tooth blocks 214 fixed on one side of the arc-shaped tooth block connecting plate 213, thereby driving the screw rod 44 to rotate in the opposite direction at the middle of the inner wall of the cross plate 42. The screw rod 44 rotates in the opposite direction while driving the columnar transmission rod 48 to move axially downward on the outer wall of the screw rod 44. The columnar transmission rod 48 moves axially downward while driving the multiple rotating rod connecting rods 49 to move downward synchronously. The multiple rotating rod connecting rods 49 move downward while driving the multiple rotating rods 410 to rotate synchronously. The multiple rotating rods 410 rotate while driving the multiple expansion plates 411 to expand synchronously, thereby releasing the limit of the optical lens after cutting.

[0041] When the lens placement mechanism 4 rotates to the front bottom of the lens discharge mechanism 3, the hydraulic push rod 35 is started, pushing the push block 312 to move forward, and the push block 312 drives the push-pull plate 39 to slide forward on the inner side of the two discharge mechanism slide slot rods 33. While the push-pull plate 39 slides forward, it blocks the bottom end of the lens placement plate 38 through the top rear side of the push-pull plate 39 to prevent the optical lenses stored in the lens placement plate 38 from falling out. When the lens discharge tube 310 is aligned with the top of the lens placement mechanism 4, the discharge tube bottom cover 311 is automatically turned open without the obstruction of the front bottom of the L-shaped connecting plate 32, and then the lens is discharged along the As the lens feeding tube 310 falls, after the falling is completed, the vertical rod 36 pulls the push block 312 to drive the push-pull plate 39 to move backward, and then the lens feeding tube 310 is realigned with the bottom of the lens placement plate 38. In this process, when the push-pull plate 39 slides backward, its top rear side no longer blocks the bottom end of the lens placement plate 38, and then the next optical lens to be fed falls into the inner wall of the lens feeding tube 310. At this time, the lens placement mechanism 4 can continue to rotate to move the next batch of optical lenses to the front bottom of the lens discharging mechanism 3, preparing for the next feeding operation, thereby realizing automated feeding and improving production efficiency.
