[0041] 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.

[0042] When the first gear 15 rotates and meshes with the fourth gear 27, the fourth gear 27 rotates, 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, and the rotation of the second rotating shaft 20 drives the rotation of the ball valve 19. The glue outlet hole 11 is opened to discharge the sealant.

[0043] As shown in the figure, Figures 6 to 9 The top of the glue coating plate 10 is embedded with a protective plug 18.

[0044] The protective plug 18 can be removed, and the sealant can be added to the glue storage plate 9 through the glue outlet hole 11 and the connecting pipe 12.

[0045] As shown in the figure, Figure 9 The second gear 16 and the fourth gear 27 are symmetrically distributed on both sides of the first gear 15.

[0046] The first gear 15 is provided as a fan-shaped gear;

[0047] During glue coating, the first gear 15 is controlled to rotate counterclockwise for one revolution, so that the first gear 15 first meshes with the second gear 16, drives the glue coating plate 10 to rotate by ninety degrees and be perpendicular to the mounting seat 4, and then meshes with the fourth gear 27, drives the ball valve 19 to rotate and opens the glue outlet hole 11.

[0048] After glue coating, the first gear 15 is controlled to rotate clockwise for one revolution, so that the first gear 15 first meshes with the fourth gear 27, drives the ball valve 19 to rotate and closes the glue outlet hole 11, and then meshes with the second gear 16, drives the glue coating plate 10 to rotate by ninety degrees and be parallel to the mounting seat 4.

[0049] As shown in Figure 9 and Figure 11 , the bottom end of the connecting pipe 12 is installed with a rotating ring 17, which is rotatably installed on the inner wall of the glue storage plate 9.

[0050] When the ring gear 8 rotates, it drives the connecting pipe 12 to rotate, and the rotation of the connecting pipe 12 drives the rotating ring 17 to rotate on the top of the glue storage plate 9.

[0051] As shown in Figures 1 to 11 , the outer wall of the connecting rod 23 is fixedly installed with a side plate 24, and the side plate 24 is provided with two, which are distributed on both sides of the glue outlet hole 11.

[0052] The thickness of the sealant is generally 1mm;

[0053] When the connecting rod 23 moves up, it drives the two side plates 24 to move up, 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 glue be controlled, but also the sealant can be prevented from overflowing from both sides, improving the quality of the glue, thereby ensuring the stability and reliability of the test.

[0054] As shown in Figure 4 , Figure 5 , Figure 7 and Figure 11 , one side of the air bag 28 is fixedly connected with the inflator pipe 30, the end of the inflator pipe 30 away from the air bag 28 is connected with the air inlet pipe 39, the inside of the air inlet pipe 39 is slidably installed with the piston head 38, one side of the piston head 38 is fixedly connected with the piston rod 37, the inside of the piston rod 37 is threadedly connected with the reciprocating screw rod 36, one end of the reciprocating screw rod 36 is fixedly installed with the second bevel gear 35, the bottom end of the second bevel gear 35 is meshingly connected with the first bevel gear 34, and the first bevel gear 34 is fixedly installed on the outer wall of the third rotating shaft 32.

[0055] The outer walls of the inflator pipe 30 and the air inlet pipe 39 are provided with one-way valves;

[0056] When the ring gear 8 rotates during glue application, 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 screw rod 36, the rotation of the reciprocating screw rod 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 in the air inlet pipe 39, the external gas is drawn through the air inlet pipe 39 and discharged from the inflator pipe 30 into the air bag 28, the air bag 28 is inflated and expanded, pushing the sealant inside the glue storage plate 9 to be discharged, facilitating continuous glue application.

[0058] A protective plug is also installed at the top of the exhaust pipe 40. When adding sealant, remove it to allow the airbag 28 to vent, so that there is enough space in the sealant storage plate 9 to add sealant.

[0059] like Figures 7 to 11 As shown, a push plate 29 is provided at the top of the airbag 28, and the push plate 29 is slidably installed inside the glue storage plate 9.

[0060] When the airbag 28 inflates, it pushes the pusher plate 29 upward within the adhesive storage plate 9, thereby assisting in the discharge of sealant. This method is more even than directly using the airbag 28 to push the sealant.

[0061] like Figure 3 As shown, the mounting base 4 has a first threaded rod 6 internally threaded, and a first motor 7 is mounted at the bottom end of the first threaded rod 6. The first motor 7 is located inside the main body 1.

[0062] The upper cavity cover 3 and the mounting base 4 are detachably connected by bolts;

[0063] Before applying the adhesive, the first motor 7 is started by controlling the PLC. When the first motor 7 starts, the first threaded rod 6 rotates. The rotation of the first threaded rod 6 drives the mounting base 4 to move. The movement of the mounting base 4 drives the upper cavity cover 3 to move down, so that the upper cavity cover 3 moves to the top of the adhesive application plate 10.

[0064] After applying the adhesive, the first motor 7 is started again by controlling the PLC. Similarly, the upper cavity cover 3 is moved to one side of the sample stage 5 and installed at the bottom of the sample stage 5 for easy testing.

[0065] After the test, the first motor 7 is started again by controlling the PLC to move the upper cavity cover 3 upward, so that the upper cavity cover 3 is separated from the sample stage 5, and the upper cavity cover 3 is removed from the bottom of the mounting base 4 for cleaning and maintenance.

[0066] Working principle and usage process:

[0067] Before testing, the film is first placed on top of the sample stage 5 or attached to the bottom of the upper cavity cover 3 after applying adhesive. Then, the second motor 13 is started by controlling the PLC. 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, causing the first gear 15 to rotate counterclockwise one revolution and mesh with the second gear 16. This causes the adhesive plate 10 to rotate 90 degrees, making it perpendicular to the mounting base 4 and located below the upper cavity cover 3.

[0068] 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, and the rotation of the second rotating shaft 20 drives the rotation of the ball valve 19 to open the glue outlet hole 11.

[0069] 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.

[0070] Then the third motor 31 is started through PLC control, the third motor 31 drives the third rotating shaft 32 to rotate when it is started, the rotation of the third rotating shaft 32 drives the rotation of the ring gear 8, the rotation of the ring gear 8 drives the rotation of the glue coating plate 10, so that the glue coating plate 10 rotates below the upper cavity cover 3 to coat sealant on the bottom end of the upper cavity cover 3.

[0071] At the same time, 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 screw rod 36, the rotation of the reciprocating screw rod 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 in the air inlet pipe 39, and the external gas is drawn through the air inlet pipe 39 and discharged from the air charging pipe 30 into the air bag 28, so that the air bag 28 is inflated and expanded to push the push plate 29 upward to push the sealant in the glue storage plate 9 out of the glue coating;

[0072] After the glue coating, the third motor 31 is turned off, the second motor 13 is started through PLC control, the first gear 15 rotates clockwise for one revolution to engage with the fourth gear 27 first, and the ball valve 19 is rotated to close the glue outlet hole 11 first, and the side plates 24 are moved downward to be withdrawn into the glue storage plate 9, and then the glue coating plate 10 is rotated to be parallel to the mounting seat 4 and is moved away from below the upper cavity cover 3.

[0073] Finally, the first motor 7 is started through PLC control, the first threaded rod 6 rotates when the first motor 7 is started, 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, and the upper cavity cover 3 is installed at the top end of the sample table 5 to be tested.
