Description

Technical Field

[0001] This utility model relates to the field of heat-sealing packaging technology, and in particular to a liquid injection heat-sealing device. Background Technology

[0002] An intraocular lens (IOL) is a small, implantable material used to replace the natural lens of the human eye. IOLs need to be immersed in a special preservation solution for extended periods to maintain their shape and function. The encapsulation method involves placing the IOL in a plastic blister pack filled with the preservation solution, and then heat-sealing the blister pack with an aluminum-plastic cap.

[0003] In related technologies, liquid injection heat sealing equipment is basically a large standard piece of equipment with complicated workstations, large size, and a large space occupation. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a liquid injection heat sealing device that allows for a more compact structure.

[0005] This utility model provides a liquid injection heat sealing device for injecting liquid into a blister pack and heat-sealing a capping material onto the blister pack. The liquid injection heat sealing device includes:

[0006] The liquid injection device includes a liquid injection end for injecting liquid into the blister pack.

[0007] The picking and placing device includes a first driving member and a picking and placing end. The picking and placing end is connected to the output end of the first driving member. The first driving member is used to drive the picking and placing end to move up and down so that the picking and placing end can grasp the cover material.

[0008] The heat sealing device includes a second driving member and a heat sealing end. The pick-and-place device and the heat sealing end are respectively connected to the output end of the second driving member. The second driving member is used to drive the pick-and-place device and the heat sealing end to move up and down, so that the cover material on the pick-and-place end is placed on the blister pack, and the cover material is heat sealed to the blister pack by the heat sealing end.

[0009] The liquid injection heat sealing device according to the embodiments of this utility model has at least the following beneficial effects:

[0010] By connecting the pick-and-place device to the output end of the second drive unit, when the output end of the second drive unit drives the heat-sealing end to move downwards, the pick-and-place device can move downwards along with the heat-sealing end. This allows the cover material on the pick-and-place end to cover the blister pack while the heat-sealing end heat-seals the cover material. During this process, the output end of the second drive unit can apply a pressing force to the cover material through the pick-and-place end, pressing the cover material tightly onto the blister pack. The heat-sealing end can heat the cover material, causing the edges of the cover material to heat-seal onto the blister pack, thus achieving heat-sealing of the cover material onto the blister pack. In this way, the picking and placing of the cover material and the heat-sealing of the cover material are performed simultaneously. The station design allows for the placement and heat sealing of the cap material at the same workstation. This simplifies the workstation design of the liquid injection heat sealing equipment, making its structure more compact and reducing its size and space requirements. Furthermore, the cap material can be heat-sealed simultaneously when placed on the blister pack, eliminating the need to transfer the blister pack to the next workstation for heat sealing. This avoids misalignment of the cap material during transfer, ensuring the alignment and sealing effect of the cap material on the blister pack. It also prevents contamination of the intraocular lens in the blister pack when the cap material is manually placed.

[0011] According to some embodiments of the present invention, the heat-sealing end includes a heat-sealing head and a heating element, the heat-sealing head is connected to the output end of the second driving element, and the heating element is connected to the heat-sealing head;

[0012] The take-up and put-out end is movable and inserted into the heat seal.

[0013] According to some embodiments of the present invention, the pick-up and put-down end includes a vacuum tube and a suction cup. The vacuum tube is movably inserted through the heat-sealed head. One end of the vacuum tube is connected to the output end of the first driving member, and the other end of the vacuum tube is connected to the suction cup. The vacuum tube is used to connect to a vacuum pumping device.

[0014] According to some embodiments of the present invention, the heat sealing head is provided with a flange, which defines a receiving cavity. The first driving member can drive the suction cup to move upward through a vacuum tube and place the suction cup in the receiving cavity.

[0015] According to some embodiments of this utility model, the flange, vacuum tube, and suction cup are coaxially arranged.

The heat sealing end is connected to one side of the heat insulation component, and the first driving component and the second driving component are connected to the other side of the heat insulation component away from the heat sealing end.

[0017] According to some embodiments of the present invention, the liquid injection device includes a liquid storage tank, a liquid injection pipe and a third driving component. The liquid injection pipe is connected to the liquid storage tank, and the liquid injection end is located at the end of the liquid injection pipe away from the third driving component. The third driving component is used to output the liquid in the liquid storage tank to the outside through the liquid injection pipe.

[0018] According to some embodiments of this utility model, the third driving component is a peristaltic pump, which is connected to the outer wall of the injection tube.

[0019] According to some embodiments of this utility model, the liquid injection heat sealing equipment further includes a worktable, which includes a fourth driving member, a first carrier, and a second carrier. The first carrier and the second carrier are respectively connected to the output end of the fourth driving member. The first carrier is used to place blister packs, and the second carrier is used to place capping materials. The fourth driving member is used to drive the first carrier and the second carrier to move to a first station or a second station.

[0020] When the first carrier and the second carrier are in the first working position, the first carrier is located below the injection end and the second carrier is located below the pick-up and drop-off end; when the first carrier and the second carrier are in the second working position, the first carrier is located below the pick-up and drop-off end.

The liquid injection device, the pick-and-place device, the heat sealing device and the worktable are respectively connected to the base, and the fifth driving member is used to drive the base to rotate.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0035] like Figure 1 As shown, this utility model embodiment provides a liquid injection heat sealing device 100, which is used to inject liquid into a blister and heat seal the capping material to the blister, thereby realizing the encapsulation of an artificial lens in the blister.

[0036] The liquid injection and heat sealing device 100 includes an injection device 10, a pick-and-place device 20, and a heat sealing device 30. The injection device 10 includes an injection end 11 for injecting liquid into the blister pack. The pick-and-place device 20 includes a first driving member 21 and a pick-and-place end 22, which is connected to the output end of the first driving member 21. The first driving member 21 drives the pick-and-place end 22 to move up and down, so that the pick-and-place end 22 grasps the capping material. The heat sealing device 30 includes a second driving member 31 and a heat sealing end 32, which are respectively connected to the output end of the second driving member 31. The second driving member 31 drives the pick-and-place device 20 and the heat sealing end 32 to move up and down, so that the capping material on the pick-and-place end 22 is placed on the blister pack, and the capping material is heat-sealed to the blister pack by the heat sealing end 32.

[0037] The following is an illustrative description of the operation process of the liquid injection heat sealing device 100 according to an embodiment of the present invention: First, the blister containing the intraocular lens can be moved below the injection end 11 and aligned with the injection end 11. Preservative solution is injected into the blister through the injection end 11 so that the intraocular lens is immersed in the preservative solution. During this process, the cap can be moved below the pick-and-place end 22 and aligned with the pick-and-place end 22. The pick-and-place end 22 is driven downward by the output end of the first driving member 21 and the cap is grasped. Then, the first driving member 21 outputs the material through the output end of the first driving member 21. The output end drives the pick-and-place end 22 to move upward; then, the blister containing the intraocular lens and preservation solution is moved to below the pick-and-place end 22 and aligned with the pick-and-place end 22. The output end of the second drive member 31 drives the pick-and-place device 20 and the heat-sealing end 32 to move downward, and the cover material on the pick-and-place end 22 is pressed onto the blister. The heat-sealing end 32 heat-melts the cover material. After the edge of the cover material melts and seals the blister, the output end of the second drive member 31 drives the pick-and-place device 20 and the heat-sealing end 32 to move upward. Thus, the encapsulation of the intraocular lens in the blister is completed.

[0038] It should be noted that the liquid injection into the blister pack and the gripping of the cap can be performed simultaneously, which can improve work efficiency. Of course, the liquid injection into the blister pack and the gripping of the cap can also be performed in stages. For example, the liquid injection into the blister pack can be performed first, followed by the gripping of the cap, or vice versa.

[0039] In this embodiment of the invention, by connecting the pick-and-place device 20 to the output end of the second driving member 31, when the output end of the second driving member 31 drives the heat-sealing end 32 to move downward, the pick-and-place device 20 can move downward together with the heat-sealing end 32. This allows the capping material on the pick-and-place end 22 to cover the blister pack while the heat-sealing end 32 heats and melts the capping material. During this process, the output end of the second driving member 31 can apply a pressing force to the capping material through the pick-and-place end 22, pressing the capping material tightly onto the blister pack. The heat-sealing end 32 can heat the capping material, causing the edges of the capping material to heat-melt onto the blister pack, thus achieving heat sealing of the capping material onto the blister pack. In this way, the pick-and-place of the capping material... The heat fusion of the cap material and the heat fusion of the cap material are performed at the same station. That is to say, the cap material can be picked up, placed, and heat-fused at the same station. This simplifies the station design of the liquid injection heat sealing equipment 100, making the structure of the liquid injection heat sealing equipment 100 more compact. The volume and space occupied by the liquid injection heat sealing equipment 100 are smaller. In addition, the heat fusion can be performed simultaneously when the cap material is placed on the blister, without the need to transfer the blister with the cap material to the next station for heat fusion. This avoids the cap material shifting during the transfer process, ensuring the alignment and sealing effect of the cap material on the blister, and avoiding contamination of the intraocular lens in the blister when the cap material is placed manually.

[0040] Furthermore, because the liquid injection heat sealing device 100 of this utility model embodiment has a small volume and space occupation, it can meet the volume requirements of the ultra-clean workbench. During use, the liquid injection heat sealing device 100 can be placed in the ultra-clean workbench, thereby reducing the risk of the artificial lens being contaminated by the working environment and helping to ensure product quality.

[0041] In some embodiments, the first driving member 21 is a first cylinder that can drive the pick-and-place end 22 to move up and down, and the second driving member 31 is a second cylinder that can drive the pick-and-place device 20 and the heat-sealing end 32 to move up and down. Of course, in some other embodiments, the first driving member 21 can also be other devices for driving the pick-and-place end 22 to move up and down, and the second driving member 31 can also be other devices for driving the pick-and-place device 20 and the heat-sealing end 32 to move up and down. For example, the first driving member 21 is a first push rod motor, and the second driving member 31 is a second push rod motor.

[0042] Please combine Figure 2 In some embodiments, the heat sealing end 32 includes a heat sealing head 321 and a heating element. The heat sealing head 321 is connected to the output end of the second driving element 31, and the heating element is connected to the heat sealing head 321. The heating element is used to heat the heat sealing head 321, and the heat sealing head 321 is used to heat melt the cover material.

[0043] The pick-and-place end 22 is movably inserted through the heat sealing head 321. The pick-and-place end 22 can shuttle back and forth relative to the heat sealing head 321 in the up and down direction to grasp the cover material and reset itself.

[0044] In this embodiment, by allowing the pick-and-place end 22 to movably pass through the heat sealing head 321, that is, by projecting along the vertical direction, the projection of the pick-and-place end 22 is at least partially located within the projection range of the heat sealing end 32. This makes the structure between the pick-and-place end 22 and the heat sealing end 32 more compact, reducing the volume and space occupation of the pick-and-place end 22 and the heat sealing end 32, which is beneficial to the miniaturization design of the liquid injection heat sealing device 100.

[0045] In some embodiments, the heating element is a heating rod disposed inside the heat sealing head 321 and used to heat the heat sealing head 321 inside the heat sealing head 321.

[0046] like Figure 2 As shown, in some embodiments, the pick-and-place end 22 includes a vacuum tube 221 and a suction cup 222. The vacuum tube 221 is movably inserted through the heat-sealing head 321. One end of the vacuum tube 221 is connected to the output end of the first driving member 21, and the other end of the vacuum tube 221 is connected to the suction cup 222. The vacuum tube 221 is used to connect to a vacuum pumping device. When the first driving member 21 drives the vacuum tube 221 to move downward, the vacuum tube 221 drives the suction cup 222 to move towards the cover material below until the suction cup 222 contacts the cover material. At this point, the vacuum tube 221 is evacuated using the vacuum pumping device, so that the suction cup 222 picks up and fixes the cover material. When the first driving member 21 drives the vacuum tube 221 to move upward, the vacuum tube 221 drives the suction cup 222 to reset and moves the cover material on the suction cup 222 upward to avoid the blister pack (containing preservation fluid and an intraocular lens) that subsequently moves to the bottom of the pick-and-place end 22.

[0047] In this embodiment, the pick-and-place end 22, by employing a combination of vacuum tube 221 and suction cup 222, is advantageous for effectively picking up and fixing materials with relatively weak rigidity, such as the cover material, thus avoiding scratches or tears on the surface of the cover material. Furthermore, when the second driving member 31 drives the pick-and-place end 22 downward and places the cover material on the blister pack, the suction cup 222 can apply a more balanced pressing force to the edge of the cover material, which can better heat-seal the cover material onto the blister pack.

[0048] After the suction cup 222 places the cover material into the blister pack, the vacuum device disconnects the vacuum tube 221 to facilitate the separation of the suction cup 222 from the cover material after the heat sealing of the cover material is completed.

[0049] like Figure 2As shown, the heat sealing head 321 is provided with a flange 3211, which defines a receiving cavity 3212. The first driving member 21 can drive the suction cup 222 to move upward through the vacuum tube 221, and place the suction cup 222 into the receiving cavity 3212. With the above configuration, when the second driving member 31 drives the pick-and-place end 22 to move downward and places the cover material on the blister, the flange 3211 is located on the periphery of the suction cup 222. In this way, the heat sealing head 321 can perform relatively uniform heat sealing on the periphery of the cover material, which is beneficial for the edge of the cover material to be better sealed on the blister after heat sealing.

[0050] When the suction cup 222 is housed in the receiving cavity 3212, the lower end of the suction cup 222 can be flush with the lower end of the flange 3211.

[0051] like Figure 2 As shown, in some embodiments, the flange 3211, vacuum tube 221 and suction cup 222 are coaxially arranged, that is, the central axes of the flange 3211, vacuum tube 221 and suction cup 222 coincide. This allows the heat sealing head 321 to have a better heat-melting effect on the periphery of the cover material, and is more conducive to sealing the edge of the cover material better on the blister after heat melting.

[0052] like Figure 2 As shown, in some embodiments, the liquid injection heat sealing device 100 further includes a heat insulation component 40, which is connected to the output end of the second drive component 31. The heat sealing end 32 is connected to one side of the heat insulation component 40, and the first drive component 21 and the second drive component 31 are connected to the other side of the heat insulation component 40 away from the heat sealing end 32. By providing the heat insulation component 40, the heat generated by the heat sealing end 32 can be blocked, reducing the heat diffusion to the side where the first drive component 21 and the second drive component 31 are located, thereby reducing the impact of the heat generated by the heat sealing end 32 on the first drive component 21 and the second drive component 31.

[0053] In some embodiments, the heat insulation member 40 may be plate-shaped. Of course, in other embodiments, the heat insulation member 40 may also have other shapes and structures, such as a cover structure that covers the heat-sealed end 32 and surrounds the outside of the heat-sealed end 32.

[0054] like Figure 1 As shown, in some embodiments, the liquid injection device 10 includes a liquid storage tank 12, an injection pipe 13, and a third driving component 14. The injection pipe 13 is connected to the liquid storage tank 12, and the injection end 11 is located at the end of the injection pipe 13 away from the third driving component 14. The third driving component 14 is used to output the liquid in the liquid storage tank 12 outward through the injection pipe 13. With the above configuration, the liquid injection heat sealing device 100 itself has a certain storage capacity of preservation liquid. The liquid injection heat sealing device 100 does not require an external liquid storage device, which facilitates the liquid injection heat sealing device 100 to inject liquid into multiple blister packs separately, reducing pipeline connections.

[0055] In some embodiments, the third driving component 14 is a peristaltic pump connected to the outer wall of the injection tube 13. By alternately squeezing and releasing the injection tube 13, the peristaltic pump can cause the liquid in the storage tank 12 to be output outward through the injection tube 13. By using a peristaltic pump, precise micro-volume liquid output can be achieved. Furthermore, when the peristaltic pump drives the liquid in the storage tank 12 to be output outward through the injection tube 13, the liquid only contacts the injection tube 13 and does not need to pass through the peristaltic pump itself. Thus, when cleaning the pipeline, only the injection tube 13 needs to be disassembled and cleaned, which facilitates the sterilization of the pipeline and reduces the risk of contamination of the stored liquid.

[0056] Of course, in some other embodiments, the third driving member 14 can also be other driving members used to output the liquid in the storage tank 12 to the outside through the injection pipe 13. For example, the third driving member 14 is a piston, which is in sealed contact with the inner wall of the storage tank 12 along the circumference of the storage tank 12. By extending the piston into the interior of the storage tank 12, the air inside the storage tank 12 can be compressed, thereby causing the stored liquid in the storage tank 12 to be output to the outside through the injection pipe 13. In addition, a clamp valve can be used as a pipeline switch to control the injection pipe 13, or a weighing device or a flow sensor can be used to detect whether the injection volume of the injection pipe 13 has reached the set value.

[0057] like Figure 1 As shown, in some embodiments, the liquid injection heat sealing device 100 further includes a worktable 50, which includes a fourth drive member 51, a first carrier 52, and a second carrier 53. The first carrier 52 and the second carrier 53 are respectively connected to the output end of the fourth drive member 51. The first carrier 52 is used to place blister packs, and the second carrier 53 is used to place capping materials. The fourth drive member 51 is used to drive the first carrier 52 and the second carrier 53 to move to the first station or the second station.

[0058] Among them, such as Figure 1 As shown, when the first carrier 52 and the second carrier 53 are in the first working position, the first carrier 52 is located below the injection end 11, and the second carrier 53 is located below the pick-and-place end 22. At this time, the injection end 11 can inject liquid into the blister containing the artificial lens on the first carrier 52 below it, and the pick-and-place end 22 can grasp the capping material on the second carrier 53 below it; Figure 3 As shown, when the first carrier 52 and the second carrier 53 are in the second working position, the first carrier 52 is located below the pick-and-place end 22. At this time, the pick-and-place end 22 can place the cover material on it onto the blister pack containing the artificial lens and preservation fluid below it, and seal the cover material onto the blister pack through the heat sealing head 321.

[0059] In some embodiments, the fourth drive member 51 may be a third cylinder, which drives the first carrier 52 and the second carrier 53 to move to the first work position or the second work position. Of course, in other embodiments, the fourth drive member 51 may also be other devices for driving the first carrier 52 and the second carrier 53 to move to the first work position or the second work position, for example, the fourth drive member 51 may be a third push rod motor.

[0060] like Figure 1 As shown, in some embodiments, the liquid injection heat sealing device 100 further includes a rotating device 60, which includes a fifth driving member and a base 61. The liquid injection device 10, the pick-and-place device 20, the heat sealing device 30 and the worktable 50 are respectively connected to the base 61. The fifth driving member is used to drive the base 61 to rotate so that the liquid injection device 10, the pick-and-place device 20, the heat sealing device 30 and the worktable 50 on the base 61 rotate with the base 61 by a certain angle, thereby realizing the angle switching of the liquid injection heat sealing device 100.

[0061] like Figure 1 As shown, in some embodiments, the liquid injection heat sealing device 100 further includes a bracket 70 and a cable base 80. The liquid injection device 10, the pick-and-place device 20, the heat sealing device 30, and the heat insulation component 40 are respectively connected to the bracket 70. The bracket 70 is connected to the base 61, and the base 61 is rotatably connected to the cable base 80. The cable base 80 is used for cable insertion and cable housing. The liquid injection device 10, the pick-and-place device 20, the heat sealing device 30, the worktable 50, and the rotating device 60 are electrically connected to the controller via cables. The fifth driving component can drive the base 61 to rotate relative to the cable base 80.

[0062] Specifically, when the liquid injection heat sealing equipment 100 is in operation, the base 61 can be rotated by the fifth driving component to make the base 61 form a first angle (e.g., 90°) with the cable base 80, thereby allowing the liquid injection device 10, the pick-and-place device 20, the heat sealing device 30, and the worktable 50 to enter the interior of the clean bench, thus reducing the risk of the intraocular lens being contaminated by the working environment. When the liquid injection heat sealing equipment 100 is not in operation, the base 61 can be rotated by the fifth driving component to make the base 61 form a second angle (e.g., 0°) with the cable base 80, thereby allowing the liquid injection device 10, the pick-and-place device 20, the heat sealing device 30, and the worktable 50 to retract into the interior of the clean bench.

[0063] In some embodiments, the injection end 11 can be connected to the bracket 70 by a support to fix the injection end 11 to the bracket 70 and keep it in a stable state, so as to prevent the injection end 11 from moving during injection.

[0064] The liquid injection and heat sealing device 100 of this utility model integrates the liquid injection device 10, the pick-and-place device 20, the heat sealing device 30, and the worktable 50 into a single device, which facilitates the miniaturization of the device. In use, after the operator places the blister pack on the first carrier 52 of the worktable 50, the control system can control the liquid injection device 10 to inject liquid into the blister pack, the pick-and-place device 20 to pick up and place the capping material, the heat sealing device 30 to heat-seal the capping material, and the worktable 50 to switch between the first carrier 52 and the second carrier 53. This allows for the encapsulation of the intraocular lens in the blister pack, making the operation simple.

[0065] Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this utility model. Furthermore, embodiments of this utility model and features thereof can be combined with each other, unless otherwise specified.
