Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 11 shown, in the embodiment of the present invention, an infrared water vapor transmittance detection device applied to a thin film includes a main body 1. A heat preservation cover 2 is hinged to the top end of the main body 1. A sample stage 5 is arranged inside the main body 1. An upper cavity cover 3 is arranged above the sample stage 5. A glue spreading assembly is arranged below the upper cavity cover 3. A mounting seat 4 is installed at the top end of the upper cavity cover 3, and the mounting seat 4 is arranged inside the main body 1; The glue - applying assembly includes a glue - applying plate 10 arranged below the upper cavity cover 3. The bottom end of the glue - applying plate 10 is rotatably connected to an annular gear 8 through a rotating assembly. An adhesive outlet hole 11 is formed inside the glue - applying plate 10, and a control assembly is arranged inside the adhesive outlet hole 11. The bottom end of the glue - applying plate 10 is fixedly connected to a connecting pipe 12. The bottom end of the connecting pipe 12 passes through the inner wall of the annular gear 8 and is embedded inside a glue - storage plate 9. An airbag 28 is arranged inside the glue - storage plate 9. One side of the annular gear 8 is meshed with a fifth gear 33. A third rotating shaft 32 is fixedly installed inside the inner wall of the fifth gear 33, and a third motor 31 is installed at the bottom end of the third rotating shaft 32; The rotating assembly includes a second motor 13 arranged inside the annular gear 8. The top end of the second motor 13 is installed with a first rotating shaft 14. A first gear 15 is fixedly installed on the outer wall of the first rotating shaft 14. One side of the first gear 15 is meshed with a second gear 16, and the second gear 16 is fixedly installed at the bottom of one end of the glue - applying plate 10.

[0021] The airbag 28 itself has a certain elastic potential energy and stores a certain amount of gas in the initial state, assisting in discharging the sealant inside the glue - storage plate 9; Before the test, first, the PLC is used to control the second motor 13 to start. When the second motor 13 starts, it drives the first rotating shaft 14 to rotate. The rotation of the first rotating shaft 14 drives the rotation of the first gear 15. The rotation of the first gear 15 drives the rotation of the second gear 16. The rotation of the second gear 16 drives the glue - applying plate 10 to rotate by ninety degrees, making the glue - applying plate 10 perpendicular to the mounting base 4 and located at the bottom of the upper cavity cover 3; Then, the PLC is used to control the third motor 31 to start. When the third motor 31 starts, it drives the third rotating shaft 32 to rotate. The rotation of the third rotating shaft 32 drives the rotation of the annular gear 8. The rotation of the annular gear 8 drives the rotation of the glue - applying plate 10, so that the glue - applying plate 10 rotates below the upper cavity cover 3 to apply sealant to the bottom end of the upper cavity cover 3. By adopting the automatic glue - applying method, not only the glue - applying is uniform, but also the test efficiency of the device can be improved.

[0022] As Figures 1 to 11 shown, the control assembly includes ball valves 19 arranged inside the adhesive outlet hole 11. The ball valves 19 are evenly distributed. Each ball valve 19 is fixedly connected through a second rotating shaft 20. One end of the second rotating shaft 20 is fixedly installed with a third gear 21. One side of the third gear 21 is meshed with a rack plate 22. The rack plate 22 is fixedly installed inside the inner wall of the connecting rod 23. The connecting rod 23 is slidably installed inside the glue - applying plate 10. A moving plate 25 is arranged at the bottom of one end of the connecting rod 23. The moving plate 25 is slidably installed inside the annular gear 8. A second threaded rod 26 is threadedly connected to the inner wall of the moving plate 25. The bottom end of the second threaded rod 26 is fixedly installed with a fourth gear 27, and the fourth gear 27 is meshed and installed on one side of the first gear 15.

[0023] The connecting rod 23 and the moving plate 25 are magnetically connected, and the connection or disconnection between the connecting rod 23 and the moving plate 25 is not affected before and after the glue storage plate 9 rotates.

[0024] When the first gear 15 rotates and meshes with the fourth gear 27, it drives the fourth gear 27 to rotate. The rotation of the fourth gear 27 drives the rotation of the second threaded rod 26. The rotation of the second threaded rod 26 drives the moving plate 25 to move upward. The movement of the moving plate 25 drives the connecting rod 23 to move upward. The movement of the connecting rod 23 drives the movement of the rack plate 22. The movement of the rack plate 22 drives the third gear 21 to rotate. The rotation of the third gear 21 drives the rotation of the second rotating shaft 20. The rotation of the second rotating shaft 20 drives the rotation of the ball valve 19, and the glue outlet hole 11 is opened for the sealant to be discharged.

[0025] As Figures 6 to 9 shown, a protective plug 18 is embedded in the top of the glue application plate 10.

[0026] The protective plug 18 can be removed, and the sealant can be added into the glue storage plate 9 through the glue outlet hole 11 and the connecting pipe 12.

[0027] As Figure 9 shown, the second gear 16 and the fourth gear 27 are symmetrically distributed on both sides of the first gear 15.

[0028] The first gear 15 is set as a sector gear; When applying glue, control the first gear 15 to rotate counterclockwise for one week, so that the first gear 15 first meshes with the second gear 16, driving the glue application plate 10 to rotate 90 degrees to be perpendicular to the mounting seat 4, and then meshes with the fourth gear 27, driving the ball valve 19 to rotate to open the glue outlet hole 11; After applying glue, control the first gear 15 to rotate clockwise for one week, so that the first gear 15 first meshes with the fourth gear 27, driving the ball valve 19 to rotate to close the glue outlet hole 11, and then meshes with the second gear 16, driving the glue application plate 10 to rotate 90 degrees to be parallel to the mounting seat 4.

[0029] As Figure 9 and Figure 11 shown, a rotating ring 17 is installed at the bottom end of the connecting pipe 12, and the rotating ring 17 is rotatably installed on the inner wall of the glue storage plate 9.

[0030] When the ring gear 8 rotates, it drives the connecting pipe 12 to rotate. The rotation of the connecting pipe 12 drives the rotating ring 17 to rotate on the top of the glue storage plate 9.

[0031] As Figures 1 to 11 shown, side plates 24 are fixedly installed on the outer wall of the connecting rod 23. There are two side plates 24, and the two side plates 24 are distributed on both sides of the glue outlet hole 11.

[0032] The coating thickness of the sealant is generally 1MM; When the connecting rod 23 moves upward, it drives the two side plates 24 to move upward, so that the two side plates 24 are located on both sides of the glue outlet hole 11. When applying glue, not only can the thickness of the applied glue be controlled, but also the sealant can be prevented from overflowing from both sides, improving the quality of the applied glue, thereby ensuring the stability and reliability of the test.

[0033] As Figure 4 , Figure 5 , Figure 7 and Figure 11 shown, one side of the airbag 28 is fixedly connected with an inflation pipe 30. The end of the inflation pipe 30 away from the airbag 28 is connected with an intake pipe 39. A piston head 38 is slidably installed inside the intake pipe 39. One side of the piston head 38 is fixedly connected with a piston rod 37. A reciprocating lead screw 36 is threadedly connected inside the piston rod 37. One end of the reciprocating lead screw 36 is fixedly installed with a second bevel gear 35. The bottom end of the second bevel gear 35 is meshed with a first bevel gear 34. The first bevel gear 34 is fixedly installed on the outer wall of the third rotating shaft 32.

[0034] One-way valves are provided on the outer walls of the inflation pipe 30 and the intake pipe 39; When applying glue during the rotation of the annular gear 8, the rotation of the third rotating shaft 32 drives the rotation of the first bevel gear 34. The rotation of the first bevel gear 34 drives the rotation of the second bevel gear 35. The rotation of the second bevel gear 35 drives the rotation of the reciprocating lead screw 36. The rotation of the reciprocating lead screw 36 drives the piston rod 37 to reciprocate. The movement of the piston rod 37 drives the piston head 38 to reciprocate inside the intake pipe 39. External gas is extracted through the intake pipe 39 and discharged into the airbag 28 through the inflation pipe 30. The airbag 28 inflates and expands, pushing the sealant inside the glue storage plate 9 out, facilitating continuous glue application.

[0035] As Figure 4 and Figure 5 shown, the top end of the inflation pipe 30 is fixedly installed with an exhaust pipe 40.

[0036] A protective plug is also installed at the top end of the exhaust pipe 40. When adding sealant, it is taken out to exhaust the airbag 28, so that there is enough space in the glue storage plate 9 to add sealant.

[0037] As Figures 7 to 11 shown, a push plate 29 is provided at the top end of the airbag 28. The push plate 29 is slidably installed inside the glue storage plate 9.

[0038] When the airbag 28 inflates and expands, it pushes the push plate 29 to move upward inside the glue storage plate 9, thereby assisting the discharge of the sealant, which is more uniform than directly using the airbag 28 to push the glue.

[0039] As Figure 3As shown, a first threaded rod 6 is internally threadedly connected to the mounting base 4, and a first motor 7 is installed at the bottom end of the first threaded rod 6. The first motor 7 is arranged inside the main body 1.

[0040] The upper cavity cover 3 and the mounting base 4 are detachably connected, namely by bolts; Before gluing, the first motor 7 is started by PLC control. When the first motor 7 starts, the first threaded rod 6 rotates. The rotation of the first threaded rod 6 drives the movement of the mounting base 4, and the movement of the mounting base 4 drives the downward movement of the upper cavity cover 3, so that the upper cavity cover 3 moves to the top of the glue application plate 10; After gluing, the first motor 7 is started again by PLC control. Similarly, the upper cavity cover 3 is moved to one side of the sample stage 5, and the upper cavity cover 3 is installed at the bottom end of the sample stage 5 for easy testing; After testing, the first motor 7 is started again by PLC control to move the upper cavity cover 3 upward, separate the upper cavity cover 3 from the sample stage 5, and remove the upper cavity cover 3 from the bottom of the mounting base 4 for cleaning and maintenance.

[0041] Working principle and usage process: Before testing, first place the film on the top of the sample stage 5 or attach it to the bottom end of the upper cavity cover 3 after gluing. Then, the second motor 13 is started by PLC control. When the second motor 13 starts, it drives the rotation of the first rotating shaft 14. The rotation of the first rotating shaft 14 drives the rotation of the first gear 15, causing the first gear 15 to rotate counterclockwise for one week and first engage with the second gear 16, thereby driving the glue application plate 10 to rotate 90 degrees to be perpendicular to the mounting base 4 and located below the upper cavity cover 3. Then the first gear 15 continues to rotate and engages with the fourth gear 27 to drive the fourth gear 27 to rotate. The rotation of the fourth gear 27 drives the rotation of the second threaded rod 26. The rotation of the second threaded rod 26 drives the upward movement of the moving plate 25. The movement of the moving plate 25 drives the upward movement of the connecting rod 23. The movement of the connecting rod 23 drives the movement of the rack plate 22. The movement of the rack plate 22 drives the rotation of the third gear 21. The rotation of the third gear 21 drives the rotation of the second rotating shaft 20. The rotation of the second rotating shaft 20 drives the rotation of the ball valve 19 to open the glue outlet hole 11. At the same time, the movement of the connecting rod 23 drives the upward movement of the two side plates 24, so that the two side plates 24 are located on both sides of the glue outlet hole 11; Then the third motor 31 is started by PLC control. When the third motor 31 starts, it drives the rotation of the third rotating shaft 32. The rotation of the third rotating shaft 32 drives the rotation of the annular gear 8. The rotation of the annular gear 8 drives the rotation of the glue application plate 10, so that the glue application plate 10 rotates below the upper cavity cover 3 to apply sealant to the bottom end of the upper cavity cover 3. Meanwhile, the rotation of the third rotating shaft 32 drives the rotation of the first bevel gear 34. The rotation of the first bevel gear 34 drives the rotation of the second bevel gear 35. The rotation of the second bevel gear 35 drives the rotation of the reciprocating lead screw 36. The rotation of the reciprocating lead screw 36 drives the reciprocating movement of the piston rod 37. The movement of the piston rod 37 drives the reciprocating movement of the piston head 38 inside the intake pipe 39. External gas is extracted through the intake pipe 39 and discharged into the airbag 28 through the inflation pipe 30. The airbag 28 inflates and pushes the push plate 29 upward, pushing the sealant inside the glue storage plate 9 out for glue application. After glue application, the third motor 31 is turned off, and the second motor 13 is started through PLC control, so that the first gear 15 rotates clockwise for one week and meshes with the fourth gear 27 first. Similarly, the ball valve 19 is rotated first to close the glue outlet hole 11, and the side plate 24 moves downward and retracts into the glue storage plate 9. Then, the glue application plate 10 rotates to be parallel to the mounting seat 4 and is removed from below the upper cavity cover 3. Finally, the first motor 7 is started through PLC control. When the first motor 7 is started, the first threaded rod 6 rotates. The rotation of the first threaded rod 6 drives the movement of the mounting seat 4. The movement of the mounting seat 4 drives the downward movement of the upper cavity cover 3, so that the upper cavity cover 3 is moved downward and installed at the top of the sample stage 5 for testing.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
