[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] As Figure 1-16As shown in the figure, a demoulding device for manufacturing contact lenses includes a heating and humidifying component 9, and an automatic feeding component 2, a first feeding component 3, a feeding tray component 4, a female die separation component 5, a female die collection component 6, a second feeding component 7, a male die collection component 8 and a lens transplanting component 10 arranged on a frame 1. The heating and humidifying component 9 is arranged on the top of the feeding tray component 4. The female die separation component 5, the female die collection component 6 and the lens transplanting component 10 are successively arranged along the assembly line direction on the periphery of the feeding tray component 4. The automatic feeding component 2 is arranged on one side of the feeding tray component 4 and is used to realize the automatic conveying of the composite material of the mould and the lens. The automatic feeding component 2 is connected to the feeding tray component 4 through the first feeding component 3, and the first feeding component 3 is used to convey and clamp the composite material of the mould and the lens onto the feeding tray component 4. The feeding tray component 4 rotates and drives the composite material of the mould and the lens to pass through the female die separation component 5 and the female die collection component 6 in sequence, completing the separation of the female die and the male die from the composite material of the lens and the collection operation of the female die. The second feeding component 7 is arranged below the feeding tray component 4 and is used to convey and lift the composite material of the male die and the lens dropped at the position of the female die separation component 5 to the central position at the top of the feeding tray component 4. The male die collection component 8 is arranged below the feeding tray component 4 and is located on one side far from the female die separation component 5.

[0048] Specifically, the present invention adopts the feeding tray component 4 to convey materials in a pipeline manner and effectively integrates multiple working components, greatly improving the integration degree of the device. While keeping the device running efficiently, the occupied space is significantly reduced, providing greater flexibility and convenience for practical applications and avoiding the problem of volume redundancy caused by the scattered arrangement of each component in the traditional device.

[0049] Specifically, the automatic feeding component 2 includes a vibrating disk 201 and a first feeding channel 202. One end of the first feeding channel 202 is communicated with the discharging end of the vibrating disk 201, and the other end of the first feeding channel 202 is communicated with the feeding end of the first feeding component 3.

[0050] Specifically, when using this device, the composite material of the mould and the lens to be demoulded is placed in the vibrating disk 201. After the vibrating disk 201 is started, through its own vibration function, the materials will be arranged and conveyed orderly along the first feeding channel 202. During this process, the first feeding channel 202 not only plays the role of conveying materials, but also precisely adjusts the posture of the injection mould to ensure that it is conveyed into the second feeding channel 308 in the correct posture with the female die facing up and the male die facing down, preparing for the subsequent demoulding operation.

[0051] Specifically, the first feeding component 3 includes a first driving motor 301, a first reciprocating lead screw 302, a first guiding chute 303, a first guiding slider 304, a first mounting plate 305, a first linear motor 306, a first positioning slider 307, a second feeding channel 308, and a material blocking block 309. The second feeding channel 308 is installed between the first feeding channel 202 and the feeding tray assembly 4, and one end of the second feeding channel 308 is communicated with the discharging end of the first feeding channel 202, and the other end of the second feeding channel 308 is communicated with the feeding end of the feeding tray assembly 4. The two material blocking blocks 309 are respectively rotatably connected to both sides of the second feeding channel 308 near the discharging end through torsion springs. The first guiding chute 303 is installed on the long side of the second feeding channel 308, and the first guiding chute 303 is arranged parallel to the second feeding channel 308. One end of the first reciprocating lead screw 302 is rotatably connected to the cavity wall of the first guiding chute 303, and the other end of the first reciprocating lead screw 302 penetrates through the cavity wall of the first guiding chute 303 and is fixedly connected to the power output end of the first driving motor 301. The first guiding slider 304 is slidably connected to the first guiding chute 303, and the first guiding slider 304 is in threaded cooperation with the first reciprocating lead screw 302. The first mounting plate 305 is fixedly connected to one end of the first guiding slider 304 away from the first guiding chute 303. The first linear motor 306 is installed on the first mounting plate 305, and the first positioning slider 307 is fixedly connected to the working end of the first linear motor 306.

[0052] Specifically, during the use process, the material blocking block 309 plays a role in restricting the moving position of the mold and lens composite material. During the specific operation, the first driving motor 301 drives the first guiding slider 304 to perform a reciprocating motion along the length direction of the first guiding chute 303 through the first reciprocating lead screw 302, and then drives the first linear motor 306 installed at the other end of the first guiding slider 304 and fixed through the first mounting plate 305 to smoothly slide along the length direction of the second feeding channel 308. The first linear motor 306 realizes the butting operation between the first positioning slider 307 and the female die of the injection mold by controlling the telescopic change of its working end, so as to realize the individual movement and clamping of the mold and lens composite material moved to the second feeding channel 308 in the first limiting groove 411.

[0053] Specifically, to ensure that the injection mold can smoothly and accurately enter the predetermined position, the height of the bottom of the inner cavity of the first feed port 408 is flush with the height position of the bottom of the material supporting plate 414. At the same time, the bottom thickness of the inner cavity of the second feeding channel 308 is the same as the thickness of the material supporting plate 414. When the second feeding channel 308 is fixedly connected to the first feed port 408, its discharge end will be in close contact with the side wall of the material supporting plate 414, and the height of the bottom of the inner cavity of the second feeding channel 308 is flush with the top height of the material supporting plate 414. Such a design enables the side wall of the punch in the injection mold to be smoothly limited and clamped in the first limiting groove 411, avoiding problems such as jamming or misalignment caused by height mismatch.

[0054] Specifically, the rotating disk 404 is suspended above the material supporting plate 414 at a certain height, that is, there is a certain gap between the bottom of the rotating disk 404 and the top of the material supporting plate 414. When the injection mold in the closed mold state is clamped in the first limiting groove 411, the bottom of the punch will contact the top of the material supporting plate 414. At this time, the material supporting plate 414 plays a supporting role for the injection mold; at the same time, the reserved gap is used to accommodate the flange at the bottom of the punch to ensure the stability and accuracy of the entire structure. In this state, the bottom flange of the female mold in the injection mold in contact with the material supporting plate 414 will be higher than the height of the second limiting groove 412 to prevent the second limiting groove 412 from hindering the movement of the injection mold.

[0055] Specifically, the feeding tray assembly 4 includes a fixed disk 401, a cross-shaped frame 402, a material blocking ring 403, a rotating disk 404, a driven gear 405, a driving gear 406, a second driving motor 407, a first feeding port 408, a discharging port 409, a second feeding port 410, a first limiting groove 411, a second limiting groove 412, a material guiding pipe 413 and a material supporting plate 414. The fixed disk 401 is erected on the top of the frame 1 through a support frame. The cross-shaped frame 402 is integrally formed with the fixed disk 401. The material blocking ring 403 is sleeved and connected to the outer peripheral side of the fixed disk 401 through the cross-shaped frame 402. The rotating disk 404 is rotatably sleeved on the fixed disk 401 and is located between the material blocking ring 403 and the fixed disk 401. The driven gear 405 is fixedly connected to the bottom of the rotating disk 404. The second driving motor 407 is installed on the frame 1 through a support frame and is located below the rotating disk 404. The driving gear 406 is fixedly connected to the power output end of the second driving motor 407 through a coupling, and the driving gear 406 meshes with the driven gear 405. A plurality of first limiting grooves 411 and second limiting grooves 412 are equidistantly arranged on the outer peripheral side of the rotating disk 404. The aperture of the second limiting groove 412 matches the outer diameter of the concave die flange, and the aperture of the first limiting groove 411 matches the outer diameter of the punch. The first feeding port 408 is opened on one side of the material blocking ring 403 close to the discharging end of the second feeding channel 308. The discharging port 409 is opened on one side of the material blocking ring 403 close to the concave die collecting assembly 6. The material supporting plate 414 arranged in a semicircular shape is fixedly connected to the top of the cross-shaped frame 402 and is located below the rotating disk 404. One end of the material supporting plate 414 is close to the first feeding port 408, and the other end of the material supporting plate 414 is close to the discharging port 409. The material guiding pipe 413 is penetrated and connected on the material supporting plate 414 and is located below the concave die separating assembly 5. The second feeding port 410 is opened at the central position of the fixed disk 401.

[0056] Specifically, the female die separating assembly 5 includes a second mounting plate 501, a second linear motor 502, second guiding chutes 503, second guiding sliders 504, a sleeve 505, a spring 506 and a second positioning slider 507. The second mounting plate 501 is mounted above the rotating disc 404 through a support frame. The second linear motor 502 is embedded in the second mounting plate 501, and the second linear motor 502 is perpendicular to the second mounting plate 501. A plurality of second guiding chutes 503 are formed on the circumferential side of the working end of the second linear motor 502. The sleeve 505 is slidably sleeved on the working end of the second linear motor 502. A plurality of the second guiding sliders 504 are arranged at equal intervals at the open end of the sleeve 505, and the second guiding sliders 504 are slidably engaged with the second guiding chutes 503. The spring 506 is embedded in the inner cavity of the sleeve 505, and one end of the spring 506 abuts against the bottom of the inner cavity of the sleeve 505, and the other end of the spring 506 abuts against the bottom of the working end of the second linear motor 502. The second positioning slider 507 is fixedly connected to the closed end of the sleeve 505.

[0057] Specifically, the spring 506 is provided to play a role of abutting and buffering, which can effectively prevent the working end of the second linear motor 502 from generating excessive contact force with the female die of the injection mold during the downward movement. At the same time, the contact surface between the second positioning slider 507 and the female die is set to be an inner concave surface, so that it can be closely attached to the top of the female die. This design increases the contact area between the second positioning slider 507 and the female die, effectively avoiding damage to the contact lenses inside the female die caused by stress concentration. By pressing down the female die, the deformation of the female die is realized, so that the separation operation of the female die, male die and the lens composite material is successfully completed without damaging the lens.

[0058] Specifically, since the material guiding pipe 413 is located directly below the second positioning slider 507, when the female die and the male die in the injection mold are successfully separated, the male die and the lens composite material will naturally fall downward under the action of gravity and accurately fall into the fourth feeding channel 701, preparing for subsequent processing. The separated female die will be in the second limiting groove 412 and, with the continuous rotation of the rotating disc 404, smoothly move into the working area of the female die collecting assembly 6 for orderly blanking and collection.

[0059] Specifically, the female die collection assembly 6 includes a third guiding chute 601, a third guiding slider 602, a third mounting plate 603, a third linear motor 604, a third positioning slider 605, a third feeding channel 606, a second reciprocating lead screw 607, a third driving motor 608, and a first material collection box 609. The first material collection box 609 and the third feeding channel 606 are evenly arranged on one side close to the discharge port 409, and the first material collection box 609 is fixedly connected to the top of the frame 1. One end of the third feeding channel 606 is communicated with the discharge port 409, and the other end of the third feeding channel 606 is communicated with the open end of the first material collection box 609.

[0060] Specifically, when the third feeding channel 606 is installed at the position of the discharge port 409, the height of the inner cavity bottom of the third feeding channel 606 is consistent with the height of the inner cavity bottom of the second limiting groove 412. This design ensures that the female die placed in the second limiting groove 412 can smoothly slide into the third feeding channel 606, thus realizing an efficient and stable material transmission process.

[0061] Specifically, the third driving motor 608 serves as a power source to drive the second reciprocating lead screw 607 to rotate, and drives the third guiding slider 602 to make a reciprocating sliding movement along the length direction of the third guiding chute 601. The third mounting plate 603 connected to the third guiding slider 602 and the third linear motor 604 installed thereon move synchronously. By precisely controlling the telescopic action of the third linear motor 604, the third positioning slider 605 can be brought into contact with the female die, ensuring the accurate feeding and positioning of the material.

[0062] Specifically, the first positioning slider 307, the second positioning slider 507, and the third positioning slider 605 all adopt the same structural configuration.

[0063] Specifically, the second feeding component 7 includes a fourth feeding channel 701, a laser sensor 702, a fourth guiding chute 703, a fourth driving motor 704, a third reciprocating lead screw 705, a fourth guiding slider 706, a fourth linear motor 707, a chuck 708, a pushing block 709, an electric telescopic rod 710, a tray 711, a fifth linear motor 712, a clamping block 713, and a material guiding groove 714. The electric telescopic rod 710 is fixedly installed on the frame 1, and the axis of the electric telescopic rod 710 coincides with the axis of the second feeding port 410. The tray 711 is fixedly connected to the telescopic end of the electric telescopic rod 710, and the size of the tray 711 matches the size of the second feeding port 410. A material guiding groove 714 is formed at the top of the tray 711. The two fifth linear motors 712 are symmetrically installed at the top of the tray 711 and are located on both sides of the material guiding groove 714. The number of the clamping blocks 713 matches the number of the fifth linear motors 712, and the clamping blocks 713 are fixedly connected to the telescopic ends of the fifth linear motors 712. The fourth feeding channel 701 is erected on the top of the frame 1 through a support frame, and the discharging end of the fourth feeding channel 701 is used to fit with the tray 711. The other end of the fourth feeding channel 701 is located directly below the discharging port of the guide pipe 413. The laser sensor 702 is embedded at one end of the fourth feeding channel 701 close to the guide pipe 413. The fourth guiding chute 703 is arranged in parallel on the long side of the fourth feeding channel 701. One end of the third reciprocating lead screw 705 is rotatably connected to the side wall of the fourth guiding chute 703, and the other end of the third reciprocating lead screw 705 penetrates through the side wall of the fourth guiding chute 703 and is rotatably connected to the power output end of the fourth driving motor 704.

The pushing block 709 is fixedly connected to the side of the chuck 708 close to the tray 711.

[0064] Specifically, the laser sensor 702 installed at the feeding end of the fourth feeding channel 701 is used to detect whether the punch and the lens complex material smoothly fall into the fourth feeding channel 701 through the guide pipe 413.

[0065] Specifically, the chuck 708 is used to implement the clamping operation on the side wall of the punch. When the punch and the lens composite material fall into the fourth feeding channel 701, the fourth driving motor 704 is started, and the fourth linear motor 707 is driven by the third reciprocating lead screw 705 to move reciprocally along the length direction of the fourth guiding chute 703. When the fourth linear motor 707 slides to the side of the fourth guiding chute 703 close to the fourth driving motor 704, its working end drives the chuck 708 and the pushing block 709 to move together towards the side close to the fourth feeding channel 701 until the chuck 708 accurately clamps onto the side wall of the punch. Subsequently, the fourth driving motor 704 rotates in the reverse direction, and through the cooperation of the third reciprocating lead screw 705 and the fourth guiding slider 706, drives the fourth linear motor 707, the chuck 708, and the pushing block 709 to move towards the direction close to the tray 711 until the punch and the lens composite material clamped in the chuck 708 are accurately placed at the central position of the material guiding groove 714 opened at the top of the tray 711. At this time, the fourth driving motor 704 stops rotating. During this process, the punch left in the material guiding groove 714 in the previous process will, under the action of the pushing block 709, smoothly fall into the second receiving box 802 through the fifth feeding channel 801.

[0066] Then, the fifth linear motors 712 arranged on both sides of the material guiding groove 714 will drive the clamping blocks 713 to move towards the center together, thereby firmly clamping the punch and the lens composite material placed in the material guiding groove 714 to ensure its stability in subsequent operations.

[0067] Finally, the electric telescopic rod 710 starts to extend, driving the tray 711 and the punch and the lens composite material firmly fixed on the tray 711 to rise smoothly until the top height of the tray 711 is exactly flush with the top height of the fixed disc 401, preparing for the next processing operation.

[0068] Specifically, the punch collection assembly 8 includes a fifth feeding channel 801 and a second receiving box 802. The fifth feeding channel 801 and the second receiving box 802 are both arranged on the opposite side of the fourth feeding channel 701, and the second receiving box 802 is fixedly connected to the top of the frame 1. One end of the fifth feeding channel 801 is used to be in contact with the tray 711, and the other end of the fifth feeding channel 801 is communicated with the opening end of the second receiving box 802.

[0069] Specifically, the heating and humidifying assembly 9 includes an annular pipeline 901, air injection holes 902 and struts 903.

[0070] Specifically, the lens transplanting assembly 10 includes a bracket 1001, a fourth mounting plate 1002, a material taking lifting cylinder 1003, a fifth mounting plate 1004, a stepping motor 1005 and a material taking vacuum suction cup 1006. The bracket 1001 arranged in an L shape is fixedly connected to the top of the frame 1. The material taking lifting cylinder 1003 is fixedly connected to the top end of the bracket 1001 through the fourth mounting plate 1002. The stepping motor 1005 is fixedly connected to the working end of the material taking lifting cylinder 1003 through the fifth mounting plate 1004. The material taking vacuum suction cup 1006 is fixedly connected to the power output end of the stepping motor 1005 through a coupling.

[0071] Specifically, the setting of the heating and humidifying assembly 9 enables water vapor at a certain temperature to be evenly sprayed onto the lens through the air injection holes 902, thereby performing a comprehensive humidifying and heating treatment on the lens. After the humidifying and heating operation is completed, the lens is separated from the convex mold under the suction force of the material taking vacuum suction cup 1006. Subsequently, the material taking lifting cylinder 1003 is activated to drive the stepping motor 1005, the material taking vacuum suction cup 1006 and the separated lens to rise to a predetermined position together. After reaching the predetermined position, the stepping motor 1005 drives the material taking vacuum suction cup 1006 and the lens to rotate and flip by 180 degrees, so that the separated lens can smoothly enter the next process for subsequent operations.
