Description

Technical Field

[0001] This utility model relates to the field of optical material packaging technology, and in particular to a moisture-proof packaging structure for an absorptive near-infrared filter. Background Technology

[0002] Absorption-type near-infrared filters selectively absorb light in the near-infrared region (typically referring to wavelengths between 780nm and 3000nm) while allowing visible light to pass through. They are commonly used in photography, sensors, and other devices that require the distinction between visible and near-infrared light.

[0003] Near-infrared filters can suffer performance degradation or damage due to environmental moisture. Current encapsulation methods often rely on simple physical isolation or manual operation, lacking systematic protection against moisture penetration. For example, during the encapsulation process of an unbonded filter, the gaps in the thin film's columnar structure are easily filled by ambient water molecules, causing the center wavelength to drift with temperature changes. While bonded filters can partially alleviate this problem, insufficient sealing of the encapsulation material cannot completely prevent moisture intrusion. Furthermore, the mechanical pressing structures of existing equipment generally lack dynamic adjustment capabilities, making it difficult to precisely control the fit between the encapsulation film and the filter, easily leading to moisture penetration due to localized gaps.

[0004] Therefore, it is necessary to design a moisture-proof packaging structure for an absorptive near-infrared filter to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a moisture-proof packaging structure for an absorptive near-infrared filter.

[0006] The technical implementation scheme of this utility model is as follows: a moisture-proof packaging structure for an absorptive near-infrared filter, including a frame, a mounting frame, a first cylinder, a pressure plate, a lower mounting plate, an upper mounting plate, a rubber ring, a second cylinder, a lifting plate, an assembly frame, a limiting rod, a plastic ring, and a pushing component. A mounting frame is provided on the top of the frame, and a first cylinder is mounted on the top of the mounting frame. The piston rod of the first cylinder points downwards and extends through the upper part of the mounting frame. A pressure plate is connected to the piston rod of the first cylinder. A lower mounting plate is provided in the middle of the top of the frame, and an upper mounting plate is hinged to the top of the lower mounting plate. A rubber ring is embedded in the bottom of the inner part of the upper mounting plate. The lower mounting plate and the upper mounting plate... Each mounting plate has a slot in the center for placing the packaging film and materials. A second cylinder is installed in the lower part of the frame. The piston rod of the second cylinder points upward and extends out of the upper part of the frame. A lifting plate is connected to the piston rod of the second cylinder. The lifting plate is located between the slots of the lower mounting plate. An assembly frame is set on the rear side of the top of the frame. Four limiting rods are symmetrically arranged along the corners of the top of the assembly frame. There is a gap between the bottom of the four limiting rods and the top of the assembly frame. A placement area is formed between each limiting rod. Multiple plastic rings are stacked in the placement area. A single plastic ring passes through the gap between the limiting rod and the assembly frame. A pushing component is set on one side of the top of the assembly frame.

[0007] Furthermore, it also includes torsion springs, with torsion springs connected to both ends of the hinge shaft of the upper and lower mounting plates.

[0008] Furthermore, it also includes a mounting block, a third cylinder, a connecting rod, and a pressure block. The mounting block is provided on one side of the lower mounting plate, and the third cylinder is installed on the top side of the frame. The upper part of the third cylinder is fixedly connected to the mounting block. The piston rod of the third cylinder faces upward and is hinged to the connecting rod. The pressure block is connected to the top side of the mounting block. A movable groove is opened in the middle of the pressure block. The upper part of the connecting rod is hinged to the movable groove of the pressure block, and the side of the pressure block presses against the top edge of the upper mounting plate.

[0009] Furthermore, the pushing component includes an electric slide rail and a push plate. An electric slide rail is installed on one side of the top of the assembly frame, and a push plate is connected to the slide seat of the electric slide rail. The push plate is located at the beginning of the gap between the limit rod and the assembly frame, and the push plate smoothly passes through the gap to move and push the plastic ring.

[0010] Furthermore, it also includes an applicator. An applicator is provided on the lower rear side of the frame. The applicator includes an adhesive tank, a pump body, a conduit, and a glue gun. An adhesive tank is installed on the lower rear side of the frame. A pump body is installed at the adhesive outlet at the lower part of the adhesive tank. A conduit is connected to the pump body. A glue gun is installed at the adhesive delivery end of the conduit.

[0011] Furthermore, the coating assembly also includes an electric cylinder, which is installed on the upper rear side of the frame. The extension rod of the electric cylinder faces upward and is connected to the glue gun, which is located in the placement area formed between each limiting rod.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model achieves mechanical pressing of the encapsulation film and the filter through the coordinated action of the frame, mounting frame, cylinder one, pressure plate, lower mounting plate, upper mounting plate and rubber ring; the linkage design of cylinder two and lifting plate further compresses the empty groove in the lower mounting plate after pressing, enhancing the tightness of the fit between the encapsulation film and the filter; the combined application of the assembly frame, limiting rod and pushing component realizes the automated supply of plastic rings.

[0013] 2. This utility model uses a torsion spring to store the elastic potential energy of the upper mounting plate during rotation. This energy assists the upper mounting plate in quickly resetting when the piston rod of the cylinder retracts, reducing operation waiting time and decreasing reliance on drive components, thus extending the service life of the equipment.

[0014] 3. This utility model uses the hinged structure design of cylinder three, connecting rod and pressure block to apply additional pressure to the upper mounting plate during the glue curing stage, ensuring that the joint between the plastic ring and the sealing film is subjected to uniform force, preventing sealing defects caused by insufficient local stress during glue curing, thereby improving the overall reliability of the moisture-proof layer.

[0015] 4. This utility model uses a combination of electric slide rail and push plate in the pushing component. The linear motion characteristics of the slide rail enable the push plate to move smoothly through the gap of the limit rod, avoiding the plastic ring offset or jamming problems that may occur in traditional manual operation, and ensuring the continuity and accuracy of material supply.

[0016] 5. This utility model integrates the glue tank, pump body, conduit and glue gun in the coating component. The pump body stably delivers glue and transmits it to the glue gun through the conduit. Combined with the vertical positioning function of the electric cylinder, the glue gun can accurately aim at the joint between the plastic ring and the sealing film, so as to achieve uniform coverage of glue spraying and effectively block the moisture penetration path.

Detailed Implementation

[0024] Example: A moisture-proof packaging structure for an absorption-type near-infrared filter, such as... Figures 1-6 As shown, the assembly includes a frame 1, a mounting frame 2, a first cylinder 3, a pressure plate 4, a lower mounting plate 5, an upper mounting plate 6, a rubber ring 61, a second cylinder 8, a lifting plate 9, an assembly frame 14, a limit rod 15, a plastic ring 151, and a pushing assembly. The frame 1 serves as the basic framework of the entire structure. The mounting frame 2 is located on the top of the frame 1, and the first cylinder 3 is mounted on the top of the mounting frame 2. The piston rod of the first cylinder 3 points downward and extends through the upper part of the mounting frame 2. The pressure plate 4 is connected to the piston rod of the first cylinder 3. The lower mounting plate 5 is located in the middle of the top of the frame 1, and the upper mounting plate 6 is hinged to the top of the lower mounting plate 5. The rubber ring 61 is embedded in the bottom of the upper mounting plate 6. The rubber ring 61 is compressed and deformed during the pressing process to form a sealed space to prevent moisture penetration. The lower mounting plate 5 and the upper mounting plate 6 both have slots in the middle for placing the packaging film and materials. The second cylinder 8 is installed in the lower part of the frame 1. The piston rod of cylinder 28 points upward and extends through the upper part of the frame 1. A lifting plate 9 is connected to the piston rod of cylinder 28. The lifting plate 9 is located between the slots of the lower mounting plate 5. Cylinder 28 drives the lifting plate 9 to rise through the vertical movement of the piston rod, further compressing the slots inside the lower mounting plate 5 and enhancing the adhesion between the encapsulation film and the filter. An assembly frame 14 is provided on the rear side of the top of the frame 1. Four limiting rods 15 are symmetrically arranged along the corners of the top of the assembly frame 14. There is a gap between the bottom of the four limiting rods 15 and the top of the assembly frame 14. A placement area is formed between each limiting rod 15. Multiple plastic rings 151 are stacked in the placement area. The plastic rings 151 serve as a moisture-proof outer layer material. They are supplied to the designated position by the pushing component and form a sealed structure after being combined with the encapsulation film. A single plastic ring 151 passes through the gap between the limiting rod 15 and the assembly frame 14. A pushing component is provided on one side of the top of the assembly frame 14.

[0025] like Figure 2As shown, it also includes a torsion spring 7. Both ends of the hinge shaft of the upper mounting plate 6 and the lower mounting plate 5 are connected to the torsion spring 7. The torsion spring 7 stores the elastic potential energy when the upper mounting plate 6 rotates, and assists the upper mounting plate 6 in resetting when the piston rod of cylinder 3 retracts, reducing the operation waiting time.

[0026] like Figure 1 and Figure 3 As shown, it also includes a mounting block 10, a cylinder 11, a connecting rod 12, and a pressure block 13. The mounting block 10 is provided on one side of the lower mounting plate 5, and the cylinder 11 is installed on the top side of the frame 1. The upper part of the cylinder 11 is fixedly connected to the mounting block 10. The piston rod of the cylinder 11 faces upward and is hinged to the connecting rod 12. The pressure block 13 is connected to the top side of the mounting block 10. The pressure block 13 has a movable groove in the middle. The upper part of the connecting rod 12 is hinged to the movable groove of the pressure block 13. The connecting rod 12 transmits the driving force of the cylinder 11 to the pressure block 13, and the pressure is applied evenly by cooperating with the pressure block 13 through the movable groove. The side of the pressure block 13 presses against the top edge of the upper mounting plate 6. The pressure block 13 moves downward by the drive of the connecting rod 12, applying pressure to the top edge of the upper mounting plate 6, further reinforcing the sealing space and ensuring the curing of the adhesive.

[0027] like Figure 4 and Figure 5 As shown, the pushing component includes an electric slide rail 16 and a pusher plate 17. The electric slide rail 16 is installed on one side of the top of the assembly frame 14. The pusher plate 17 is connected to the slide seat of the electric slide rail 16. The electric slide rail 16 provides the linear motion trajectory of the pusher plate 17 to ensure the accurate pushing of the plastic ring 151. The pusher plate 17 is located at the starting end of the gap between the limit rod 15 and the assembly frame 14. The pusher plate 17 smoothly passes through the gap to push the plastic ring 151. The pusher plate 17 moves under the drive of the electric slide rail 16 to push the plastic ring 151 from the stacking area to the designated position.

[0028] like Figure 5 and Figure 6 As shown, it also includes an applicator. The applicator is located on the lower rear side of the frame 1. The applicator includes an adhesive tank 18, a pump body 19, a conduit 20, and a glue gun 22. The adhesive tank 18 is installed on the lower rear side of the frame 1. The adhesive tank 18 is used to store adhesive. The pump body 19 is installed at the adhesive outlet at the lower part of the adhesive tank 18. The pump body 19 is connected to the conduit 20. The conduit 20 serves as a delivery channel for the adhesive. The glue gun 22 is installed at the glue delivery end of the conduit 20 to receive the adhesive delivered by the conduit 20 and spray it onto the inside of the plastic ring 151 by driving.

[0029] like Figure 5 and Figure 6As shown, the coating assembly also includes an electric cylinder 21. The electric cylinder 21 is installed on the upper rear side of the frame 1. The telescopic rod of the electric cylinder 21 faces upward and is connected to the glue gun 22. The glue gun 22 is located in the placement area formed between each limiting rod 15. The electric cylinder 21 drives the glue gun 22 to move up and down through the vertical movement of the telescopic rod, so that it is precisely aligned with the spraying position.

[0030] First, the operator places the encapsulation film and filter into the empty slots in the middle of the lower mounting plate 5 and the upper mounting plate 6. At this time, the upper mounting plate 6 is in its natural state and not fully closed with the lower mounting plate 5. Then, cylinder 3 is activated, and its piston rod extends downward, pushing the pressure plate 4 gradually closer to the upper mounting plate 6. Subsequently, the operator manually flips the cover to move the upper mounting plate 6 downward until it is fully closed with the lower mounting plate 5. During this process, the rubber ring 61 embedded at the bottom of the upper mounting plate 6 is compressed and deformed, forming a sealed space and providing a preliminary moisture-proof environment for subsequent encapsulation. At the same time, the torsion springs 7 installed at both ends of the hinge shaft store elastic potential energy due to the rotation of the upper mounting plate 6, providing auxiliary power for subsequent reset.

[0031] After the upper mounting plate 6 and the lower mounting plate 5 are closed, cylinder 8 begins to operate. Its piston rod extends upward, pushing the lifting plate 9 upward from the lower part of the frame 1. The upward movement of the lifting plate 9 further compresses the empty slot inside the lower mounting plate 5, thereby enhancing the adhesion between the encapsulation film and the filter, ensuring the tightness of the encapsulation structure. At the same time, the assembly rack 14 located at the rear top of the frame 1 enters the working state. Multiple plastic rings 151 are stacked in the placement area formed by the gaps between the four limiting rods 15 at the top of the assembly rack 14. The electric slide rail 16 in the push assembly is activated, driving the push plate 17 to move from the starting end toward the plastic rings 151. The push plate 17 smoothly passes through the gap between the limiting rods 15 and the assembly rack 14, pushing the bottommost plastic ring 151 to the designated position, providing a moisture-proof outer layer material for subsequent encapsulation.

[0032] After the plastic ring 151 is in place, the application assembly begins operation. The pump 19 inside the glue tank 18 activates, delivering glue through the conduit 20 to the glue gun 22. The telescopic rod of the electric cylinder 21 moves the glue gun 22 downwards, precisely aligning it with the joint between the plastic ring 151 and the encapsulation film. The glue gun 22 evenly sprays glue at this position, ensuring the glue layer covers all gaps where moisture might penetrate. At this time, the cylinder 3 11 activates, its piston rod extending upwards, pushing the pressure block 13 downwards through the hinge structure of the connecting rod 12 and the pressure block 13. The engagement of the movable groove of the pressure block 13 with the connecting rod 12 applies pressure evenly to the top edge of the upper mounting plate 6, further reinforcing the closed state of the upper mounting plate 6 and the lower mounting plate 5, while ensuring the glue fully penetrates and cures, forming a stable moisture-proof layer.

[0033] Once the adhesive has cured, the piston rod of cylinder 3 begins to retract, and the pressure plate 4 rises accordingly. At this time, the torsion spring 7 releases its stored elastic potential energy, assisting the upper mounting plate 6 in rotating back to its initial position around the hinge axis, releasing the pressure on the encapsulation film and the filter. Simultaneously, the piston rod of cylinder 8 retracts, and the lifting plate 9 descends to its original position, releasing the pressure in the empty slot inside the lower mounting plate 5. At this point, the encapsulated filter is retained in the sealed structure formed by the plastic ring 151 and the encapsulation film, and its moisture-proof performance is guaranteed by both adhesive curing and mechanical pressing.
