Description

Technical Field

[0001] The invention belongs to the field of optical lens packaging, in particular to an optical lens packaging device. Background Art

[0002] Optical lenses are very important components of optical elements. They achieve specific optical functions by adjusting the propagation, focusing or dispersion of light. Common materials include glass and resin, which have excellent optical properties, including high light transmittance, constant refractive index and stable physical and chemical properties.

[0003] The packaging design of optical lenses needs to take into account the protection, storage and safety of the lenses during transportation; this includes covering the outside of the lenses with a film to reduce the impact of external dust and water vapor on the optical lenses, and also to reduce damage to the lenses caused by scratches;

[0004] However, optical lenses are often not in a flat state, and the film cannot be directly attached to the lens surface using the flattening film method. In addition, many optical lenses are easily damaged in high temperature environments, and thermoplastic films cannot be used to wrap the optical lenses. As a result, it is difficult for traditional packaging equipment to cover the surface of the optical lens with a protective film for protection.

[0005] To this end, the present invention provides an optical lens packaging device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: an optical lens packaging device described in the present invention comprises a packaging box, two feeders symmetrically arranged in an upper and lower direction are arranged on the inner side of the packaging box, the feeders are composed of two rotatable winding rollers, a separation film is connected between the two winding rollers, a plurality of bonding films adapted to the lenses to be packaged are distributed above the separation film, a binding frame for fixing the lenses to be packaged is arranged on the inner side of the packaging box, the binding frame is located between the two feeders, a vertical pressing seat capable of being lifted and lowered is arranged on the outer side of the feeder, and two negative pressure machines capable of providing negative pressure to the pressing seat are arranged at one end of the pressing seat away from the separation film;

[0008] By setting up the packaging box and the binding frame, the lens to be packaged is placed in the binding frame, and then the four winding rollers rotate synchronously and in the same direction to move the two bonding films to the upper and lower ends of the lens to be packaged, and the bonding film is pressed by the pressing seat. The area of ​​the bonding film is larger than the bottom area of ​​the pressing seat, and the bottom area of ​​the pressing seat is the same as the surface area of ​​the lens to be packaged. The connection between the bonding film and the separation film is processed by opening holes, and under the pressure of the pressing seat, the separation film can be separated from the bonding film more easily. The separation process is: first let the pressing seat and the separation film fit together, and then start the negative pressure machine to generate negative pressure to adsorb the bonding film, and then drive the pressing seat to make the bonding film close to the lens to be packaged. Since the bonding film is fitted with the pressing seat as a whole at this time, the force generated by the pressure will not cause wrinkles in the bonding film. When the bonding film is fitted with the lens to be packaged, the bonding film and the pressing seat are curved on one side facing the lens to be packaged, and the curvature is the same as that of the bonding film. The lenses to be packaged are the same, so that the separation film can be tightly covered on the lenses to be packaged. At the same time, the lenses to be packaged have been electrostatically treated before packaging so that their surfaces carry charges, so that the bonding film and the lenses to be packaged will bond to each other under the action of electrostatic adsorption, and then the adsorption of the negative pressure machine is turned off, and at the same time the pressing seat is away from the lenses to be packaged, so that the bonding film and the pressing seat are separated from each other. At this time, the upper and lower sides of the lenses to be packaged are wrapped by the separation film, and the packaging work of the lenses to be packaged is completed. The packaged lenses are taken out, and then the winding roller rotates to move the new bonding film to the middle, waiting for the next packaging work. Through this setting, the packaging and laminating work on both sides of the optical lens is realized, the whole process is mechanized and controlled, and the automation is relatively high. The hot melt mechanism is not used to heat the bonding film, so that the bonding film is naturally bonded to the surface of the lens to be packaged. The entire packaging process does not cause damage to the optical lens, thereby ensuring the quality of the finished product after packaging.

[0009] Preferably, a transfer box is installed at the front end of the packaging box, and two symmetrically arranged conveyor belts are installed inside the transfer box, and a plurality of placement tables are fixedly connected to the top transport end of the conveyor belt, and a servo motor for adjusting the position of the binding frame is installed on the outer side of the middle part of the transfer box, and the top surface of the transfer box is rotatably connected to sealing doors on both sides. The sealing doors are opened, and the processed lenses to be packaged are placed on the placement table below the sealing doors. With the transportation of the conveyor belt, the lenses to be packaged are transferred to one side of the servo motor, and the servo motor controls the binding frame to change its position and grabs the lenses to be packaged. After being grabbed and fixed, the lenses to be packaged are moved between two separation films for laminating packaging. After processing is completed, the servo motor controls the binding frame to move to the conveyor belt on the other side, and places the packaged lenses on the placement table. With the operation of the conveyor belt, the lenses are finally moved to the bottom of the sealing door for easy removal. Through this arrangement, the entire packaging equipment is highly automated. It only needs to cooperate with the lens delivery mechanism and the lens recovery mechanism to continuously deliver and recover the lenses, so as to complete the fully automated packaging of the lenses, effectively improving the packaging efficiency.

[0010] Preferably, the pressing seat is arranged in an arc shape at one end facing the separation membrane, and its curvature is adapted to the curvature of the lens to be packaged. The bonding film is also arranged in an arc shape. A plurality of connecting holes connected to the negative pressure machine are opened at one end of the pressing seat facing the separation membrane. At the bottom of the pressing seat, the arc-shaped pressing seat will also be arc-shaped. The arc-shaped bonding film can be bonded with the pressing seat without wrinkles. The negative pressure generated by the negative pressure machine generates negative pressure through the plurality of connecting holes to adsorb the bonding film. After the bonding film is bonded to the lens to be packaged, the negative pressure of the negative pressure machine is turned off, so that the bonding film can remain on the outside of the lens to be packaged by electrostatic adsorption, thereby completing the bonding work of the bonding film.

[0011] Preferably, an annular sleeve is fixedly connected to the outer side of one end of the pressing seat facing the separation membrane, and a separation pad is fixedly connected to the inner ring of the annular sleeve. The separation pad is woven from a flexible material and can pass airflow through the separation pad. An air pump is fixedly connected to the middle part of the end of the pressing seat away from the separation membrane, and the air pump is connected to a plurality of connecting holes. When the negative pressure generated by the negative pressure machine acts on its own curved surface, the negative pressure force will adsorb the separation pad, allowing the flexible separation pad to fit the curved surface. At the same time, part of the negative pressure can still pass through the separation pad because the air permeable mesh cover structure woven from fine filaments of the separation pad is itself affected by the negative pressure tension. At the same time, part of the negative pressure will also pass through the separation pad. Such a setting will make the negative pressure more evenly dispersed on the surface of the separation pad after passing through the separation pad, thereby generating more uniform suction on the surface of the bonding membrane and reducing damage and deformation to the bonding membrane. At the same time, after the bonding film is bonded to the lens to be packaged, in order to ensure a tight fit, the pressing seat is allowed to continue to maintain a bonding state, and the middle air pump is started. Since the air pump is at the center of the pressing seat, the air pressure will come between the separation pad and the pressing seat. In order to be discharged outward, the air pressure will move outward from the center. During the movement, the pressure of the air pressure acts on the separation pad, and the separation pad indirectly presses the bonding film, so that the bonding film is pressed from the center position to the outside on the surface of the lens to be packaged, ensuring that the bonding film and the lens to be packaged are seamlessly bonded. Since the separation pad is made of flexible material, the entire compression process is uniform and powerful, and the effect and quality are better than direct compression using air pressure. Through this setting, not only can the bonding film be pressed onto the surface of the lens to be packaged without a gap, but also due to the output of air pressure, the bonding film and the pressing seat can be easily separated at this time.

[0012] Preferably, the binding frame is composed of two semicircular frames, wherein two symmetrically arranged electric telescopic rods three are fixedly connected to the outer side of one of the semicircular frames, and the output end of the electric telescopic rod three is fixedly connected to the other semicircular frame. The binding frame is arranged in a form that is narrow in the center and wide at both ends. The two semicircular frames can be separated from each other by extending the electric telescopic rod three. After being transferred to the outside of the lens to be packaged, the electric telescopic rod three is shortened to close the two semicircular frames, thereby clamping the lens to be packaged, thereby completing the function of fixing and releasing the lens to be packaged; according to the structural setting of the binding frame, the binding frame will only clamp the middle part of the lens to be packaged, thereby not hindering the bonding process of the bonding film; at the same time, when the bonding film is required to cover the lens to be packaged In the case of the side of the lens, the following operations are required: after the binding frame fixes the lens to be packaged and moves it between the two separation films, the two pressing seats will stick the bonding film to the upper and lower surfaces of the lens to be packaged, and then the two semicircular frames will separate so that the semicircular frames no longer contact the lens to be packaged. When it is necessary to wrap the side of the lens to be packaged, the area of ​​the prepared bonding film needs to be larger than the surface of the lens to be packaged, so that after the bonding film is attached to the lens to be packaged, the edge of the bonding film will exceed the lens to be packaged, and then the air pumps of the upper and lower pressing seats will be started successively, and the air pressure generated will not only make the bonding film stick to the lens to be packaged, but also the bonding film at the edge will be attached to the side of the lens to be packaged under the action of the airflow leaked from the side of the pressing seat. Since the upper and lower air pumps are started successively, the edges of the two bonding films are attached to the side of the lens to be packaged, and the edges of the two bonding films will also overlap each other. Finally, the binding frame will press and fix the side of the lens to be packaged, and the edges of the two bonding films will be pressed and fixed to the side of the lens to be packaged, thereby realizing the function of fully wrapping the lens to be packaged.

[0013] Preferably, an electric telescopic rod 2 for driving the semicircular frame to move is fixedly connected to the middle part of the outer side of one of the semicircular frames, and the electric telescopic rod 2 is connected to the output end of the servo motor. The servo motor can drive the electric telescopic rod 3 and the restraining frame to rotate, and move the restraining frame to the top of the conveyor belt or between the separation films. At the same time, when grabbing and releasing the lens to be packaged, the electric telescopic rod 3 and the electric telescopic rod 2 can be started synchronously. For example, when fixing the lens to be packaged, the electric telescopic rod 3 is first extended to separate the two semicircular frames, and the electric telescopic rod 2 is shortened to adjust the position of the restraining frame. In this way, there is enough space between the two semicircular frames to grab the lens to be packaged, and the lens to be packaged remains still and stable during fixing and releasing, thereby ensuring stability during fixing and releasing.

[0014] Preferably, the bonding film is composed of an electrostatic adsorption film and an isolation film, the electrostatic adsorption film faces the lens to be packaged, and the isolation film is made of elastic material. When the electrostatic adsorption film contacts the lens to be packaged, it will be bonded to the lens to be packaged under the action of electrostatic adsorption of electric charge, and the isolation film has a certain elasticity. The contact pressure between the bonding film and the pressing seat and the deformation pressure generated during extrusion will be absorbed by the isolation film, and the electrostatic adsorption film will not be affected, thereby ensuring the flatness of the electrostatic adsorption film.

[0015] Preferably, one end of the winding roller is fixedly connected to a driving motor for driving the winding roller to rotate, and the driving motor is fixedly connected to a packaging box. Two sets of restraining seats for restraining the outer edge of the separation membrane are fixedly connected in the packaging box. The winding roller is driven to rotate by the driving motor, and the arc-shaped bonding film is wound around the outside of the winding roller. There are convex or concave structures with the same curvature of the bonding film on the winding surface of the winding roller, which ensures that the bonding film can still maintain its own arc state when it is in a wound state, and the arrangement distance of the bonding film on the outside of the separation membrane is also predetermined, which ensures that when the separation membrane is in a wound state, the inner and outer layers of the bonding film are overlapped with each other, so that the bonding film can be rolled up in an arc state.

[0016] Preferably, the restraining seat is arranged in an elongated strip shape, and a slot is provided on the side of the restraining seat facing the separation membrane, and the edge of the separation membrane is slidably engaged in the slot. The arrangement of the restraining seat allows the discharged separation membrane to always remain on a predetermined horizontal plane, so that the pressing seat can use the same force each time to separate the laminated membrane.

[0017] Preferably, a connecting frame is fixedly connected to the outer side of the pressing seat, the connecting frame is fixedly connected to the electric telescopic rod 1, the electric telescopic rod 1 is fixedly connected to the packaging box, the connecting frame connects the electric telescopic rod 1 and the pressing seat, and the connecting frame is fixed to the side of the pressing seat, which will not affect the normal operation of the air pump and the negative pressure machine.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The optical lens packaging equipment described in the present invention realizes the packaging and laminating work on both sides of the optical lens through the setting of the packaging box and the binding frame. The whole process is mechanized and highly automated, and no hot melt mechanism is used to heat the bonding film, so that the bonding film can be naturally bonded to the surface of the lens to be packaged. The entire packaging process does not cause damage to the optical lens, thereby ensuring the quality of the finished product after packaging.

[0020] 2. The optical lens packaging equipment described in the present invention places the processed lenses to be packaged on a placement table below the sealing door, and with the transportation of the conveyor belt, the lenses to be packaged are transferred to one side of the servo motor, and the servo motor controls the binding frame to change its position and grabs the lenses to be packaged. After being grabbed and fixed, the lenses to be packaged are moved between two separation films for coating and packaging. After the processing is completed, the servo motor controls the binding frame to move to the conveyor belt on the other side, and places the packaged lenses on the placement table. With the operation of the conveyor belt, the lenses are finally moved to the bottom of the sealing door for easy removal. Through this setting, the entire packaging equipment is highly automated. It only needs to cooperate with the lens delivery mechanism and the lens recovery mechanism to continuously deliver and recover the lenses to complete the fully automated packaging of the lenses, effectively improving the packaging efficiency.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 8 As shown, an optical lens packaging device according to an embodiment of the present invention comprises a packaging box 1, wherein two feeders 5 symmetrically arranged in an upper and lower direction are arranged inside the packaging box 1, wherein the feeders 5 are composed of two rotatable winding rollers 9, wherein a separation film 13 is connected between the two winding rollers 9, wherein a plurality of laminating films 14 adapted to lenses 16 to be packaged are distributed above the separation film 13, wherein a restraining frame 17 for fixing the lenses 16 to be packaged is arranged inside the packaging box 1, wherein the restraining frame 17 is located between the two feeders 5, wherein a vertical pressing seat 24 capable of being lifted and lowered is arranged outside the feeders 5, wherein two negative pressure machines 22 capable of providing negative pressure to the pressing seat 24 are arranged at one end of the pressing seat 24 away from the separation film 13;

[0033] When working, traditional optical lenses need to be coated on the outside to reduce the impact of external dust and water vapor on the optical lenses during the subsequent transportation process. However, optical lenses are often not in a flat state, and the film cannot be directly attached to the lens surface by attaching a flat film. In addition, many optical lenses are easily damaged in high temperature environments, and thermoplastic films cannot be used to wrap the optical lenses. As a result, it is difficult for traditional packaging equipment to cover the surface of optical lenses with protective films for protection.

[0034] For example, a high-precision camera lens is a convex lens with arc-shaped upper and lower surfaces. It is necessary to cover both sides of the lens with a protective film. However, laminating on two arc-shaped surfaces is not only prone to errors in the operation process, but also difficult to achieve mechanical automation processing with traditional packaging equipment;

[0035] Through the arrangement of the packaging box 1 and the binding frame 17, the lens 16 to be packaged is placed in the binding frame 17, and then the four winding rollers 9 rotate synchronously and in the same direction, so that the two bonding films 14 move to the upper and lower ends of the lens 16 to be packaged, and the bonding film 14 is pressed by the pressing seat 24. The area of ​​the bonding film 14 is larger than the bottom area of ​​the pressing seat 24, and the bottom area of ​​the pressing seat 24 is the same as the surface area of ​​the lens 16 to be packaged. The connection between the bonding film 14 and the separation film 13 is processed by opening a hole, and under the pressure of the pressing seat 24, the bonding film 14 is pressed. The separation film 13 can be separated from the bonding film 14 relatively easily. The separation process is as follows: firstly, the pressing seat 24 is made to bond with the separation film 13, and then the negative pressure machine 22 is started to generate negative pressure to adsorb the bonding film 14. Then, the bonding film 14 is driven by the pressing seat 24 to approach the lens 16 to be packaged. Since the bonding film 14 is bonded to the pressing seat 24 as a whole at this time, the force generated by the pressure will not cause the bonding film 14 to wrinkle. When the bonding film 14 is bonded to the lens 16 to be packaged, the bonding film 14 and the pressing seat 24 are facing the lens 16 to be packaged. One side of the film 16 is arc-shaped, and the arc is the same as that of the lens 16 to be packaged, so that the separation film 13 can be tightly covered on the lens 16 to be packaged. At the same time, the lens 16 to be packaged has been electrostatically treated before packaging, so that its surface carries a charge, so that the bonding film 14 and the lens 16 to be packaged can be bonded to each other under the action of electrostatic adsorption, and then the adsorption of the negative pressure machine 22 is turned off, and the pressing seat 24 is away from the lens 16 to be packaged, so that the bonding film 14 and the pressing seat 24 are separated from each other. At this time, the upper and lower surfaces of the lens 16 to be packaged are The lens 16 to be packaged is wrapped by the separation film 13, and the packaging work of the lens to be packaged 16 is completed. The packaged lens is taken out, and then the winding roller 9 rotates to move the new bonding film 14 to the middle, waiting for the next packaging work. Through this arrangement, the packaging and laminating work on both sides of the optical lens is realized, and the whole process is mechanized and controlled, with high automation. The bonding film 14 is not heated by a hot melt mechanism, so that the bonding film 14 is naturally bonded to the surface of the lens 16 to be packaged. The entire packaging process does not cause damage to the optical lens, thereby ensuring the quality of the finished product after packaging.

[0036] A transfer box 2 is installed at the front end of the packaging box 1, and two symmetrically arranged conveyor belts 6 are installed inside the transfer box 2. A plurality of placement tables 7 are fixedly connected to the top transport end of the conveyor belt 6. A servo motor 8 for adjusting the position of the restraining frame 17 is installed on the outer side of the middle part of the transfer box 2. The top surface of the transfer box 2 is rotatably connected to the sealing door 4 on both sides.

[0037] During operation, the sealing door 4 is opened, and the processed lens 16 to be packaged is placed on the placement table 7 below the sealing door 4. With the transportation of the conveyor belt 6, the lens 16 to be packaged is transferred to one side of the servo motor 8. The servo motor 8 controls the binding frame 17 to change its position and grabs the lens 16 to be packaged. After being grabbed and fixed, the lens 16 to be packaged is moved between the two separation films 13 for coating and packaging. After the processing is completed, the servo motor 8 controls the binding frame 17 to move to the conveyor belt 6 on the other side, and places the packaged lens on the placement table 7. With the operation of the conveyor belt 6, the lens is finally moved to the bottom of the sealing door 4 for easy removal. Through this setting, the entire packaging equipment is highly automated. It only needs to cooperate with the lens delivery mechanism and the lens recovery mechanism to continuously deliver and recover the lenses to complete the fully automated packaging of the lenses, effectively improving the packaging efficiency.

[0038] The end of the pressing seat 24 facing the separation film 13 is arranged in an arc shape, and its curvature is adapted to the curvature of the lens 16 to be packaged. The laminating film 14 is also arranged in an arc shape. The end of the pressing seat 24 facing the separation film 13 is provided with a plurality of communication holes 26 connected to the negative pressure machine 22.

[0039] When working, the bottom of the pressing seat 24, when working, the arc-shaped pressing seat 24 will also be arc-shaped, and the arc-shaped bonding film 14 can be bonded with the pressing seat 24 without wrinkles. The negative pressure generated by the negative pressure machine 22 generates negative pressure through multiple connecting holes 26 to adsorb the bonding film 14. When the bonding film 14 is bonded to the lens 16 to be packaged, the negative pressure of the negative pressure machine 22 is turned off, so that the bonding film 14 can rely on electrostatic adsorption to remain on the outside of the lens 16 to be packaged, thereby completing the bonding work of the bonding film 14.

[0040] The outer side of the end of the press-fit seat 24 facing the separation membrane 13 is fixedly connected with an annular sleeve 20, and the inner circle of the annular sleeve 20 is fixedly connected with a separation pad 25, and the separation pad 25 is woven from a flexible material, and the separation pad 25 can pass the airflow, and the middle part of the end of the press-fit seat 24 away from the separation membrane 13 is fixedly connected with an air pump 23, and the air pump 23 is connected with a plurality of communication holes 26;

[0041] During operation, when the negative pressure generated by the negative pressure machine 22 acts on its own curved surface, the negative pressure force will absorb the separation pad 25, allowing the flexible separation pad 25 to fit the curved surface. At the same time, part of the negative pressure can still pass through the separation pad 25, because the separation pad 25 is a breathable mesh structure woven from fine filaments, which is itself affected by the negative pressure tension. At the same time, part of the negative pressure will also pass through the separation pad 25. This arrangement will make the negative pressure more evenly dispersed on the surface of the separation pad 25 after passing through the separation pad 25, thereby generating a more uniform suction force on the surface of the bonding film 14, reducing damage and deformation to the bonding film 14. At the same time, after the bonding film 14 is bonded to the lens 16 to be packaged, in order to ensure a tight fit, the pressing seat 24 is first allowed to continue to remain in the bonding state, and the air pump 23 is started. Since the air pump 23 is located at the center of the pressing seat 24, the air pressure will come between the separation pad 25 and the pressing seat 24. In order to be discharged outward, the air pressure will move outward from the center. During the movement, the pressure of the air pressure acts on the separation pad 25, and the separation pad 25 indirectly presses the bonding film 14, so that the bonding film 14 is pressed from the center position to the outside on the surface of the lens to be packaged 16, ensuring that the bonding film 14 and the lens to be packaged 16 are seamlessly bonded. Since the separation pad 25 is made of flexible material, the entire pressing process is uniform and powerful, and the effect and quality are better than that of direct pressing with air pressure. Through this arrangement, not only can the bonding film 14 be pressed onto the surface of the lens to be packaged 16 without a gap, but also due to the output of air pressure, the bonding film 14 and the pressing seat 24 can be easily separated at this time.

[0042] The binding frame 17 is composed of two semicircular frames 18, wherein two symmetrically arranged electric telescopic rods 19 are fixedly connected to the outer side of one of the semicircular frames 18, and the output end of the electric telescopic rod 19 is fixedly connected to the other semicircular frame 18. The binding frame 17 is arranged in a form of being narrow in the center and wide at both ends;

[0043] During operation, the two semicircular frames 18 can be separated from each other by extending the electric telescopic rod 3 19, and after being transferred to the outside of the lens 16 to be packaged, the electric telescopic rod 3 19 is shortened to close the two semicircular frames 18, thereby clamping the lens 16 to be packaged, so that the function of fixing and releasing the lens 16 to be packaged can be completed; the structural setting of the binding frame 17 is that the binding frame 17 will only clamp the middle part of the lens 16 to be packaged, so as not to hinder the bonding process of the bonding film 14; at the same time, when the bonding film 14 is required to cover the side of the lens 16 to be packaged, the following operation is required: when the binding frame 17 fixes the lens 16 to be packaged and moves it between the two separation films 13, the two bonding films 14 are pressed together. The seat 24 adheres the bonding film 14 to the upper and lower surfaces of the lens 16 to be packaged, and then the two semicircular frames 18 are separated so that the semicircular frames 18 no longer contact the lens 16 to be packaged. When it is necessary to wrap the side of the lens 16 to be packaged, the area of ​​the prepared bonding film 14 needs to be larger than the surface of the lens 16 to be packaged. In this way, after the bonding film 14 is adhered to the lens 16 to be packaged, the edge of the bonding film 14 will exceed the lens 16 to be packaged, and then the air pumps 23 of the upper and lower pressing seats 24 are started successively. The generated air pressure will not only make the bonding film 14 adhere to the lens 16 to be packaged, but also the edge of the bonding film 14 will be adhered to the side of the lens 16 to be packaged under the action of the airflow leaked from the side of the pressing seat 24. As the upper and lower air pumps 23 are started successively, the edges of the two bonding films 14 are bonded to the sides of the lens 16 to be packaged, and the edges of the two bonding films 14 are also overlapped with each other. Finally, the binding frame 17 presses and fixes the sides of the lens 16 to be packaged, and the edges of the two bonding films 14 are pressed and fixed to the sides of the lens 16 to be packaged, thereby realizing the function of fully wrapping the lens 16 to be packaged.

[0044] A second electric telescopic rod 15 for driving the semicircular frame 18 to move is fixedly connected to the middle of the outer side of one of the semicircular frames 18, and the second electric telescopic rod 15 is connected to the output end of the servo motor 8;

[0045] During operation, the servo motor 8 can drive the electric telescopic rod three 19 and the binding frame 17 to rotate, and move the binding frame 17 to the top of the conveyor belt 6 or between the separation films 13. At the same time, when grabbing and releasing the lens 16 to be packaged, the electric telescopic rod three 19 and the electric telescopic rod two 15 can be started synchronously. For example, when fixing the lens 16 to be packaged, the electric telescopic rod three 19 is first extended to separate the two semicircular frames 18. At the same time, the electric telescopic rod two 15 is shortened to adjust the position of the binding frame 17. In this way, there is enough space between the two semicircular frames 18 to grab the lens 16 to be packaged. The lens 16 to be packaged remains still and stable during fixing and releasing, thereby ensuring stability during fixing and releasing.

[0046] The laminating film 14 is composed of an electrostatic adsorption film 27 and an isolation film 28, wherein the electrostatic adsorption film 27 faces the lens 16 to be packaged, and the isolation film 28 is made of elastic material;

[0047] During operation, when the electrostatic adsorption film 27 contacts the lens 16 to be packaged, it will adhere to the lens 16 to be packaged under the action of electrostatic adsorption of electric charge, and the isolation film 28 has a certain elasticity. The contact pressure between the bonding film 14 and the pressing seat 24 and the deformation pressure generated during extrusion will be absorbed by the isolation film 28, and the electrostatic adsorption film 27 will not be affected, thereby ensuring the flatness of the electrostatic adsorption film 27.

[0048] One end of the winding roller 9 is fixedly connected to a driving motor 10 for driving the winding roller 9 to rotate. The driving motor 10 is fixedly connected to the packaging box 1. Two sets of binding seats 12 for binding the outer edges of the separation membrane 13 are fixedly connected to the packaging box 1.

[0049] During operation, the winding roller 9 is driven to rotate by the driving motor 10, and the arc-shaped laminating film 14 is wound around the outside of the winding roller 9. The winding surface of the winding roller 9 has a convex or concave structure with the same curvature of the laminating film 14, which ensures that the laminating film 14 can still maintain its own arc-shaped state when it is in the wound state, and the arrangement distance of the laminating film 14 on the outside of the separation membrane 13 is also predetermined, which ensures that when the separation membrane 13 is in the wound state, the inner and outer layers of the laminating film 14 are overlapped with each other, so that the laminating film 14 can be rolled up in an arc-shaped state.

[0050] The binding seat 12 is arranged in a long strip shape, and a slot is provided on one side of the binding seat 12 facing the separation membrane 13, and the edge of the separation membrane 13 is slidably engaged in the slot;

[0051] During operation, the setting of the restraining seat 12 allows the discharged separation film 13 to always remain on a predetermined horizontal plane, so that the pressing seat 24 can use the same force each time to separate the laminating film 14.

[0052] The outer side of the pressing seat 24 is fixedly connected with a connecting frame 21, the connecting frame 21 is fixedly connected to the electric telescopic rod 11, and the electric telescopic rod 11 is fixedly connected to the packaging box 1;

[0053] During operation, the connecting frame 21 connects the electric telescopic rod 11 and the pressing seat 24 , and the connecting frame 21 is fixed to the side of the pressing seat 24 , which will not affect the normal operation of the air pump 23 and the negative pressure machine 22 .

[0054] During operation, the lens 16 to be packaged is placed in the binding frame 17 through the arrangement of the packaging box 1 and the binding frame 17, and then the four winding rollers 9 rotate synchronously and in the same direction, so that the two bonding films 14 move to the upper and lower ends of the lens 16 to be packaged, and the bonding film 14 is pressed by the pressing seat 24. The area of ​​the bonding film 14 is larger than the bottom area of ​​the pressing seat 24, and the bottom area of ​​the pressing seat 24 is the same as the surface area of ​​the lens 16 to be packaged. The connection between the bonding film 14 and the separation film 13 is processed by opening a hole, and the pressing seat 24 is pressed to press the bonding film 14. Under the condition that the separation film 13 can be separated from the bonding film 14 more easily, the separation process is as follows: firstly, the pressing seat 24 is made to be bonded with the separation film 13, then the negative pressure machine 22 is started to generate negative pressure to adsorb the bonding film 14, and then the bonding film 14 is driven by the pressing seat 24 to approach the lens 16 to be packaged. Since the bonding film 14 is bonded with the pressing seat 24 as a whole at this time, the force generated by the pressure will not cause the bonding film 14 to wrinkle. When the bonding film 14 is bonded with the lens 16 to be packaged, the bonding film 14 and the pressing seat 24 are facing the lens 16 to be packaged. One side of the lens 16 is arc-shaped, and the arc is the same as that of the lens 16 to be packaged, so that the separation film 13 can be tightly covered on the lens 16 to be packaged. At the same time, the lens 16 to be packaged has been electrostatically treated before packaging, so that its surface carries a charge, so that the bonding film 14 and the lens 16 to be packaged can be bonded to each other under the action of electrostatic adsorption. Then, the adsorption of the negative pressure machine 22 is turned off, and the pressing seat 24 is away from the lens 16 to be packaged, so that the bonding film 14 and the pressing seat 24 are separated from each other. At this time, the upper and lower surfaces of the lens 16 to be packaged are The lenses 16 to be packaged are all wrapped by the separation film 13, and the packaging work of the lenses to be packaged 16 is completed. The packaged lenses are taken out, and then the winding roller 9 rotates to move the new bonding film 14 to the middle, waiting for the next packaging work. Through this arrangement, the packaging and laminating work on both sides of the optical lens is realized, and the whole process is mechanized and highly automated. The bonding film 14 is not heated by a hot melt mechanism, so that the bonding film 14 is naturally bonded to the surface of the lens 16 to be packaged. The entire packaging process does not cause damage to the optical lens, ensuring the quality of the finished product after packaging.

[0055] The sealing door 4 is opened, and the processed lens 16 to be packaged is placed on the placement table 7 below the sealing door 4. With the transportation of the conveyor belt 6, the lens 16 to be packaged is transferred to one side of the servo motor 8. The servo motor 8 controls the binding frame 17 to change its position and grabs the lens 16 to be packaged. After being grabbed and fixed, the lens 16 to be packaged is moved between two separation films 13 for film coating and packaging. After the processing is completed, the servo motor 8 controls the binding frame 17 to move to the conveyor belt 6 on the other side, and places the packaged lens on the placement table 7. With the operation of the conveyor belt 6, the lens is finally moved to the bottom of the sealing door 4 for easy removal. Through this setting, the entire packaging equipment is highly automated. It only needs to cooperate with the lens delivery mechanism and the lens recovery mechanism to continuously deliver and recover the lens to complete the fully automated packaging of the lens, which effectively improves the packaging efficiency.

[0056] At the bottom of the pressing seat 24, when working, the arc-shaped pressing seat 24 will also be arc-shaped, and the arc-shaped laminating film 14 can be laminated with the pressing seat 24 without wrinkles. The negative pressure generated by the negative pressure machine 22 generates negative pressure through multiple connecting holes 26 to adsorb the laminating film 14. After the laminating film 14 and the lens 16 to be packaged are laminated, the negative pressure of the negative pressure machine 22 is turned off, so that the laminating film 14 can rely on electrostatic adsorption to stay on the outside of the lens 16 to be packaged, and the laminating work of the laminating film 14 is completed;

[0057] When the negative pressure generated by the negative pressure machine 22 acts on its own curved surface, the negative pressure force will absorb the separation pad 25, allowing the flexible separation pad 25 to fit the curved surface. At the same time, part of the negative pressure can still pass through the separation pad 25, because the separation pad 25 is a breathable mesh cover structure woven from fine filaments, which is itself affected by the negative pressure tension. At the same time, part of the negative pressure will also pass through the separation pad 25. This arrangement will make the negative pressure more evenly dispersed on the surface of the separation pad 25 after passing through the separation pad 25, thereby generating a more uniform suction force on the surface of the bonding film 14, reducing damage and deformation to the bonding film 14. At the same time, after the bonding film 14 is bonded to the lens 16 to be packaged, in order to ensure a tight fit, the pressing seat 24 is first allowed to continue to maintain a bonding state, and the middle air pump 23 is started. When the air pump 23 is at the center of the pressing seat 24, the air pressure will come between the separation pad 25 and the pressing seat 24. In order to be discharged outward, the air pressure will move outward from the center. During the movement, the pressure of the air pressure acts on the separation pad 25, and the separation pad 25 indirectly presses the bonding film 14, so that the bonding film 14 is pressed from the center to the outside on the surface of the lens 16 to be packaged, ensuring that the bonding film 14 and the lens 16 to be packaged are seamlessly bonded. Since the separation pad 25 is made of a flexible material, the entire pressing process is uniform and powerful, and the effect and quality are better than that of direct pressing with air pressure. Through this arrangement, not only can the bonding film 14 be pressed on the surface of the lens 16 to be packaged without gaps, but also due to the output of air pressure, the bonding film 14 and the pressing seat 24 can be easily separated at this time;

[0058] By extending the electric telescopic rod 3 19, the two semicircular frames 18 can be separated from each other and transferred to the outside of the lens 16 to be packaged, and then the electric telescopic rod 3 19 is shortened to close the two semicircular frames 18, thereby clamping the lens 16 to be packaged, so that the function of fixing and releasing the lens 16 to be packaged can be completed; the structural setting of the binding frame 17 is that the binding frame 17 will only clamp the middle part of the lens 16 to be packaged, so as not to hinder the bonding process of the bonding film 14; at the same time, when the bonding film 14 is required to cover the side of the lens 16 to be packaged, the following operations are required. When the binding frame 17 fixes the lens 16 to be packaged and moves it between the two separation films 13, the two pressing seats 2 The laminating film 14 is laminating on the upper and lower surfaces of the lens 16 to be packaged, and then the two semicircular frames 18 are separated so that the semicircular frames 18 no longer contact the lens 16 to be packaged. When it is necessary to wrap the side of the lens 16 to be packaged, the area of ​​the prepared laminating film 14 needs to be larger than the surface of the lens 16 to be packaged, so that after the laminating film 14 is laminating on the lens 16 to be packaged, the edge of the laminating film 14 will exceed the lens 16 to be packaged, and then the air pumps 23 of the upper and lower pressing seats 24 are started successively, and the generated air pressure will not only make the laminating film 14 laminating on the lens 16 to be packaged, but also the edge of the laminating film 14 will be laminating on the side of the lens 16 to be packaged under the action of the airflow leaking from the side of the pressing seat 24. As the upper and lower air pumps 23 are started successively, the edges of the two laminating films 14 are laminating to the side of the lens 16 to be packaged, and the edges of the two laminating films 14 are also overlapped with each other, and finally the binding frame 17 presses and fixes the side of the lens 16 to be packaged, and the edges of the two laminating films 14 are pressed and fixed to the side of the lens 16 to be packaged, thereby achieving the function of fully wrapping the lens 16 to be packaged;

[0059] The servo motor 8 can drive the electric telescopic rod 3 19 and the binding frame 17 to rotate, and move the binding frame 17 to the top of the conveyor belt 6 or between the separation films 13. At the same time, when the lens 16 to be packaged is grabbed and released, the electric telescopic rod 3 19 and the electric telescopic rod 2 15 can be started synchronously. For example, when fixing the lens 16 to be packaged, the electric telescopic rod 3 19 is first extended to separate the two semicircular frames 18, and the electric telescopic rod 2 15 is shortened to adjust the position of the binding frame 17, so that there is enough space between the two semicircular frames 18 to grab the lens 16 to be packaged. When fixing and releasing, the lens 16 to be packaged remains still and stable, thereby ensuring stability during fixing and releasing;

[0060] When the electrostatic adsorption film 27 contacts the lens 16 to be packaged, it will be attached to the lens 16 to be packaged under the action of electrostatic adsorption of electric charges. The isolation film 28 has a certain elasticity. The contact pressure between the laminating film 14 and the pressing seat 24 and the deformation pressure generated during the extrusion will be absorbed by the isolation film 28, and the electrostatic adsorption film 27 will not be affected, thereby ensuring the flatness of the electrostatic adsorption film 27.

[0061] The winding roller 9 is driven to rotate by the driving motor 10, and the arc-shaped laminating film 14 is wound on the outside of the winding roller 9. The winding surface of the winding roller 9 has a convex or concave structure with the same curvature of the laminating film 14, which ensures that the laminating film 14 can still maintain its own arc state when it is wound, and the arrangement distance of the laminating film 14 outside the separation film 13 is also predetermined, which ensures that when the separation film 13 is wound, the inner and outer layers of the laminating film 14 are overlapped with each other, so that the laminating film 14 is rolled up in an arc state;

[0062] The setting of the restraining seat 12 allows the discharged separation film 13 to always remain on a predetermined horizontal plane, so that the pressing seat 24 can use the same force each time to separate the laminating film 14;

[0063] The connecting frame 21 connects the electric telescopic rod 11 and the pressing seat 24. The connecting frame 21 is fixed to the side of the pressing seat 24 and will not affect the normal operation of the air pump 23 and the negative pressure machine 22.
