Description

Technical Field

[0001] The present invention belongs to the technical field of single mold cutting of contact lenses, and specifically relates to an automatic cutting and demoulding machine for a single mold. Background Art

[0002] When contact lenses are produced, resin molds are needed to shape the contact lenses, so that the silicone hydrogel can be injected into the resin mold for curing and molding. When the resin molds of contact lenses are produced, injection molding machines are needed for batch processing. When the resin molds of contact lenses are molded, the molds are also needed to cure the resin, so that the resin molds can mold the contact lens raw materials.

[0003] In the manufacturing process of contact lenses, the contact lenses are made by combining the upper and lower molds. When taking out the lenses, the upper and lower molds are first separated. After separation, the lenses adhere to the molds. The excess material on the side of the upper mold is cut off, and then the mold is heated. The lens is taken out using the lens taking mechanism.

[0004] In the prior art, the patent name: A device and method for extracting dry contact lens sheets, patent number: CN111113963B, discloses a device for extracting dry contact lens sheets, the device includes a dry sheet semi-finished product conveying mechanism, a mold separation mechanism, a collecting mechanism, a dividing plate assembly, a dry sheet taking out mechanism and a dry sheet conveying and storage mechanism; the present invention also provides a method for extracting dry sheets using the device; the present invention utilizes the vibration of the vibration plate in the dry sheet semi-finished product conveying mechanism to send the dry sheet into the mold separation mechanism through a linear conveying track; then utilizes the mold separation mechanism to separate the upper and lower molds of the dry sheet and send them into the collecting mechanism; then utilizes the collecting mechanism to transfer the dry sheet to the dividing plate assembly; then utilizes the dividing plate assembly to soften and separate the lower mold of the dry sheet; then utilizes the dry sheet taking out mechanism to transfer the dry sheet to the dry sheet conveying and storage mechanism; finally utilizes the dry sheet conveying and storage mechanism to realize the conveying and storage of the dry sheet; the present invention replaces the existing manual production mode by adopting automated equipment and methods, thereby solving the problems of high labor intensity and low production efficiency.

[0005] However, the existing equipment uses an automated demoulding device for demoulding, which directly cuts the upper mold and the lower mold from both sides with a cutter. However, since the mold shape of the contact lens is circular, and the upper mold and the lower mold are sealed by downward pressure hot nails, there will be a circle of annular equidistant hot welding points between the joints of the upper and lower molds. However, only cutting the mold with the cutters on both sides will still make it impossible for the upper and lower molds to be fully separated, resulting in the upper mold cannot be sucked out smoothly, resulting in demoulding failure, and the existing demoulding machine can only suck out the upper mold, and cannot directly take out the contact lens, resulting in a waste of production capacity. Even if a robotic arm can be directly set up on top to take the lens, it is still impossible to remove the excess lower mold for discharge, and it is impossible to achieve cyclic automated production. Summary of the invention

[0006] In order to solve the above problems, this paper proposes an automatic cutting and demoulding machine for a single mold, the left end of the cutting and demoulding machine is connected to the vibrating material tray through a discharging conveyor, and a plurality of independent single-mold contact lens molds are arranged inside the vibrating material tray, and the cutting and demoulding machine is provided with a cutting turntable, a mold opening and dividing turntable, a lower mold transfer turntable, a lower mold discharging trough, a material moving clamp arm and a film taking and demoulding turntable from left to right in sequence, the left side of the mold cutting turntable is mutually conductive with the vibrating material tray through the discharging conveyor, the right side of the mold cutting turntable is tangentially connected to the mold opening and dividing turntable, a turntable cutter is arranged on the outside of the rear side of the mold cutting turntable, and a reverse dial is arranged on the inner side of the mold cutting turntable, the mold opening and dividing turntable is an upper and lower double-layer mold opening turntable, the upper right side of the mold opening and dividing turntable is connected to the upper mold discharging port through the upper mold discharging trough, the lower right side of the mold opening and dividing turntable is tangentially connected to the lower mold transfer turntable, the right side of the lower mold transfer turntable is vertically connected to the lower mold discharging trough, and the lower A lower mold heater is provided on the outer rear side of the mold transfer tray, and a material transfer clamp arm is provided on the right side of the lower mold discharge groove in a horizontally movable manner. The right side of the material transfer clamp arm is connected to the film removal and mold ejection turntable, and the four vertical sides of the film removal and mold ejection turntable are provided with a feeding position, a film ejection machine, a film removal position and a lower mold discharge port in a counterclockwise manner from left to right. By improving the original linear mold cutting and mold splitting and adopting the form of an S-shaped multiple turntable, not only can the upper and lower molds be fully cut by the circular cutter, but also the upper and lower molds can be opened and divided automatically by the double-layer mold opening and material dividing turntable. The upper mold discharges the lower mold and transports it to the next section for heating, discharging and ejecting to prepare for the film removal operation. Finally, the lower mold that has completed the film removal can be discharged, completing repeated and efficient automated mold opening production, without the need to transfer to the next step for special film removal operation. The efficiency is improved and the cleanliness and hygiene of the production process can be ensured to prevent pollution.

[0007] The shape of the vibrating material tray is an annular spiral single-mold loading tray. A discharge conveyor is horizontally arranged above the right side of the vibrating material tray. The left end of the discharge conveyor is connected to the vibrating material tray, and the right end of the discharge conveyor is tangently connected to the outer arc of the die cutting turntable.

[0008] The outer edges of the die cutting turntable, the die opening and material dividing turntable and the lower die material transfer plate are all provided with a plurality of die clips, which mesh and intersect with each other according to the number and rotation speed between each other. By arranging mold openings on the outer edges of the die cutting turntable, the die opening and material dividing turntable and the lower die material transfer plate, the rotation speed of these clips can be adjusted according to the different sizes and number of clips of the turntables, thereby realizing the mutual meshing and alternation between these turntables, thereby completing the mutual alternation of the molds.

[0009] A turntable cutter is provided on the rear side of the die-cutting turntable in a mutually tangent manner. The turntable cutter is in the shape of a disc-shaped rotating cutter. The blade of the turntable cutter is aligned with the mold joint in the mold bayonet of the die-cutting turntable for cutting. The lower inner side of the die-cutting turntable is rotated by the mold in the mold bayonet of the die-cutting turntable through a reverse dial wheel. The turntable cutter and the reverse dial wheel rotate in opposite directions with the die-cutting turntable. By having a rotating cutter and a reverse dial wheel, the mold in the mold bayonet can be cut while the mold is rotated in the opposite direction, so that the cutter can fully cut, thereby ensuring that the hot nails between the upper mold and the lower mold are cut completely.

[0010] A mold bayonet is arranged on the outer side of the lower rotating disk of the mold opening and material dividing turntable, and an upper pull rod is arranged on the rear side of the mold bayonet of the mold opening and material dividing turntable. An upper and lower slope lifting disk is arranged on the upper end of the mold opening and material dividing turntable, and the inner side of the upper pull rod is connected to the rotation of the mold opening and material dividing turntable, and the upper end of the upper pull rod is displaced up and down with the top surface of the upper and lower slope lifting disk through the guide wheel, and a lifting step is arranged on the right side of the upper and lower slope lifting disk, and a descending step is arranged on the left side of the upper and lower slope lifting disk, and the bottom surface of the upper pull rod is flush with the upper mold discharge trough through the lifting steps of the upper and lower slope lifting disk, and the lower rotating disk of the mold opening and material dividing turntable The right side of the disk is tangent to the left side of the lower mold transfer disk. The upper mold can be pulled upwards through the upper pull rod through the mold opening and dividing turntable, thereby completing the mold opening of the upper and lower molds, and the upper pull rod can be driven to move up and down through the up and down slope lifting disk. The mold opening and dividing turntable can pull the upper mold up and down and send it into the upper mold discharge trough to complete the upper mold discharge through the upper mold discharge port. When the upper pull rod rotates to the left, it can automatically descend to grab the newly entered mold, completing the automated upper and lower mold dividing operation, and the separated lower mold can enter the lower mold transfer disk from the lower layer to proceed to the next step.

[0011] A lower mold heater is provided at the outer edge of the rear side of the lower mold transfer disk, and a lower mold discharge groove is provided on the right side of the lower mold transfer disk in a longitudinal and horizontal tangent manner. The lower mold heater is provided at the outer side of the mold clamp of the lower mold transfer disk, and a conveyor belt with a material shifting clamp arm is provided horizontally on the outer side of the front end of the lower mold discharge groove. The material shifting clamp arm is longitudinally provided above the lower mold discharge groove, and the front end of the material shifting clamp arm is moved horizontally by the horizontal conveyor belt. The material shifting clamp arm is moved to the rightmost end and is aligned with each other above the feeding position of the film removal and ejection turntable. Through the lower mold transfer disk, not only can the lower mold that originally moves in an arc be discharged in a regular manner through the lower mold discharge groove, which is convenient for the subsequent grabbing and displacement of the material shifting clamp arm, but also the lower mold heater arranged therebetween can be used to facilitate the subsequent top film and film removal operations of the contact lens to prevent sticking.

[0012] The film taking and demoulding turntable is a four-way vertical indexing turntable. Mold material racks are arranged at the four corners of the outer edge of the film taking and demoulding turntable. The left, right, front and rear directions of the film taking and demoulding turntable are respectively provided with a feeding position, a film taking position, a film ejecting machine and a lower mold discharge port. The film taking and demoulding turntable rotates counterclockwise at a fixed angle. Through the four-way film taking and demoulding turntable, the feeding and film taking operations at the left and right ends are realized, and the ejecting and discharging operations can also be set at the front and rear positions, thus forming a complete cycle of mold taking and film taking, and a complete contact lens can be directly obtained.

[0013] Beneficial effects:

[0014] By improving the original linear die cutting and parting into an S-shaped multiple turntable, not only can the upper and lower molds be fully cut by the circular cutter, but the upper and lower molds can also be opened and divided automatically by the double-layer mold opening and material dividing turntable. The upper mold is discharged and the lower mold is transported to the next section for heating, discharging and top material preparation to prepare for the operation of taking the film. Finally, the lower mold that has completed the film taking can be discharged, completing repeated and efficient automatic mold opening production, without the need to transfer to the next step for special film taking operation. The improvement of efficiency can also ensure the cleanliness and hygiene of the production process, prevent pollution, and further compress the volume of the overall device and reduce the floor space required for production.

[0015] By arranging mold openings on the outer edges of the mold cutting turntable, the mold opening and material dividing turntable and the lower mold transfer turntable, the rotation speed of these openings can be adjusted according to the different sizes and numbers of openings of the turntables, thereby realizing the mutual engagement and alternation between these turntables, thereby completing the mutual alternation of the molds.

[0016] By having a rotating cutter and a reverse dial wheel, the mold in the mold bayonet can be cut while the mold is rotated in the opposite direction, so that the cutter can fully cut, thereby ensuring that the hot nails between the upper mold and the lower mold are cut completely.

[0017] The upper mold can be pulled upwards through the upper pull rod through the mold opening and dividing turntable, thereby completing the mold opening of the upper and lower molds, and the upper pull rod can be driven to move up and down through the up and down slope lifting plate. The upper mold can be pulled up and down by the mold opening and dividing turntable and sent into the upper mold discharge trough to complete the upper mold discharge through the upper mold discharge port. When the upper pull rod rotates to the left, it can automatically descend to grab the newly entered mold, completing the automated upper and lower mold dividing operation, and the separated lower mold can enter the lower mold transfer tray from the lower layer to proceed to the next step.

[0018] The lower die material transfer plate can not only discharge the lower die, which originally moves in an arc shape, in an orderly manner through the lower die material discharge groove, making it easier for the subsequent material transfer clamp arm to grab and move the material, but also can pass the lower die heater arranged therebetween, making it easier for the subsequent top sheet and sheet removal operations of the contact lens to prevent sticking.

[0019] The four-way film removal and demoulding turntable can realize the feeding and film removal operations at the left and right ends, and the top film and discharge operations can be set at the front and back positions, thus forming a complete cycle of mold removal and directly obtaining complete contact lenses.
