Description

Technical Field

[0001] The invention belongs to the technical field of adhesive detection, and in particular relates to an anti-fatigue testing device for nano-imprint adhesive production. Background Art

[0002] Nanoimprint adhesive is a special material, mainly used in nanoprinting technology to prepare micro-nano structures; these structures are widely used in optics, electronics, biomedicine and other fields; there are many types of nanoimprint adhesives, including UV-curable adhesives, thermal-curable adhesives and hot-melt adhesives; UV-curable adhesives are prepared by UV-curing technology, and after the imprinting is completed, the adhesive material is rapidly cured by irradiating UV light to form the required micro-nano structures; thermal-curable adhesives need to be cured by heating, while hot-melt adhesives are in a molten state at a certain temperature and are cured by cooling after imprinting; at present, after the preparation of nanoimprint adhesives, the nanoimprint adhesives need to be tested for shear strength. The specific test steps of shear strength are to first bond two sheet specimens according to the specified area and bonding process conditions, and then fix them on the special fixture of the tensile testing machine for uniform stretching, so that the bonding layer is subjected to increasingly large shear external forces until the bonding layer separates, and finally the shear bonding strength of the polyurethane adhesive is calculated based on the bonding area and the measured force.

[0003] However, when the existing tensile testing machine is performing shear strength testing, two sheet specimens need to be manually loaded, and after the test is completed, the two separated sheet specimens need to be manually removed, and then the bonding area is measured. The operation is cumbersome, and the nanoimprint glue on the two sheet specimens needs to be manually removed after one test before they can be used subsequently. In addition, since the existing tensile testing machine is generally used at room temperature, it is impossible to test the fatigue resistance of the nanoimprint glue under different ambient temperatures and humidity, resulting in a small detection range, making the test data unconvincing.

The fatigue resistance test device also includes: a driving mechanism 7, which is fixedly connected to the detection box 1. The driving mechanism 7 includes a fixed plate 701 fixedly connected to the detection box 1, and three servo motors 702 are fixedly connected to one side of the fixed plate 701. The output ends of the three servo motors 702 are fixedly connected to bidirectional threaded rods 703. Three vertical slide grooves 704 are provided on the fixed plate 701. The three bidirectional threaded rods 703 are respectively arranged in the three vertical slide grooves 704 and are rotatably connected to the vertical slide grooves 704. A first gear 705 is fixedly connected to the middle of the bidirectional threaded rod 703. Three horizontal slide grooves 706 are provided on the top of the fixed plate 701. The horizontal slide grooves 706 are connected to the vertical slide grooves 704. Six supporting blocks 707 are fixedly connected to the top of the fixed plate 701.The fatigue resistance testing device also includes: a pulling mechanism 8, which is arranged in the detection box 1 and is used to pull the two clamped sheet test pieces to the two ends. The pulling mechanism 8 is driven by the driving mechanism 7. The pulling mechanism 8 is arranged in three groups. One group of pulling mechanisms 8 includes two pulling blocks 801. The bottoms of the two pulling blocks 801 are fixedly connected with slide plates 802. The slide plates 802 are slidably connected with the vertical slide grooves 704. The slide plates 802 are slidably connected with a limiting screw ring 803 that passes through the slide plates 802. One side of the slide plates 802 is fixedly connected with a second magnetic ring 809, and the other side of the slide plates 802 is fixedly connected with a magnetic sheet 807. The limiting screw ring 803 is fixedly connected with a first magnetic ring 808. The first magnetic ring 808 is arranged opposite to the second magnetic ring 809, and the magnetic properties of the two opposite sides are opposite. The limiting screw ring 803 and the bidirectional screw The threaded rod 703 is connected by a thread, and a turntable 804 is rotatably connected to the opposite side of the pulling block 801. A tension sensor is installed between the two pulling blocks 801 in a pulling mechanism 8. The tension sensor is used to record the shear tension under which the sheet specimen is pulled apart after being coated with the nanoimprint glue (the pressure sensor is a prior art, not shown in the figure, and will not be described in detail here). The turntable 804 cannot rotate by itself without external force. An electric clamping plate 805 is installed on the opposite side of the turntable 804, and a supporting plate 806 is fixedly connected to the opposite side of the turntable 804. The supporting plate 806 is arranged below the electric clamping plate 805. The fatigue resistance test device for nanoimprint glue production also includes an extrusion mechanism 9, a glue injection mechanism 10, a detection mechanism 11 and a flip mechanism 12. ;

[0022] When used for the first time, the box door 2 is opened and two sheet specimens are placed on two supporting plates 806 in a group of pulling mechanisms 8 respectively. At this time, the electric clamping plate 805 can be started to clamp and fix the sheet specimens. The bonding surfaces of the two sheet specimens are within the area where the supporting block 707 is located. At this time, the glue injection mechanism 10 is full of nano-imprint glue, and then the box door 2 is closed and the detection mechanism 11 is started to move downward to drive the flipping mechanism 12 to flip the sheet specimen, so that the bonding surface of the sheet specimen is located in the detection mechanism 11, and then the detection mechanism 11 is covered on the bonding surface of the sheet specimen, and then the servo motor 702 is started to reverse, driving the bidirectional threaded rod 703 to rotate, so that the slide plate 802 passes through the first The first magnetic ring 808 and the second magnetic ring 809 move inwards under the action of the limiting screw ring 803, so that the glue injection mechanism 10 sprays the nano-imprint glue on the bonding surface of the sheet specimen, and the slide plate 802 drives the pulling block 801 to move inwards, thereby moving the two sheet specimens inwards, so that the bonding surfaces of the two sheet specimens overlap, and then the slide plate 802 is limited, and the limiting screw ring 803 continues to move inwards, and the first magnetic ring 808 is separated from the attracted state of the second magnetic ring 809, and the rotation of the bidirectional threaded rod 703 will cause the extrusion mechanism 9 to clamp the parts of the two sheet specimens with the nano-imprint glue until the end of the limiting screw ring 803 without the first magnetic ring 808 contacts the slide plate 802; After the two sheet specimens are bonded by the nanoimprint adhesive and fixed together by the squeezing mechanism 9, the servo motor 702 is started to make the bidirectional threaded rod 703 rotate forwardly. At this time, since the limiting screw ring 803 is connected to the bidirectional threaded rod 703 by threads, and the magnetic end of the limiting screw ring 803 is not in contact with the slide plate 802, the limiting screw ring 803 will slide to both ends under the rotation of the bidirectional threaded rod 703 and the limiting effect of the slide plate 802, and the squeezing mechanism 9 is gradually opened and no longer squeezes the nanoimprint adhesive bonding part until the limiting screw ring 803 and the slide plate 802 are attracted by the first magnetic ring 808 and the second magnetic ring 809. At this time, the limiting screw ring 803 will drive the slide plate 802 to slide outward along the vertical slide groove 704, and then pull the two sheet specimens to both ends through the electric clamping plate 805, so that the nanoimprint adhesive bonded between the two sheet specimens is subjected to shear force until the bonding parts of the two sheet specimens are pulled apart, and the servo motor 702 can be turned off at this time; In addition, it should be noted that when the shear fatigue resistance test of the nanoimprint adhesive is carried out under low temperature, room temperature and high temperature environments, the above steps are followed.

[0023] like Figure 1 , Figure 5 , Figure 6 , Figure 8 , Fig.12 , Fig.13 , Fig.14 and Fig.16As shown, the glue injection mechanism 10 is fixedly connected to the detection mechanism 11, and the glue injection mechanism 10 is used to apply nano-imprint glue to the sheet test piece. The glue injection mechanism 10 includes a glue box 1001, and the glue box 1001 is fixedly connected to the top of the fixed plate 701. The side of the glue box 1001 close to the pulling block 801 is fixedly connected with a glue extraction tube 1002, and the glue discharge end of the glue extraction tube 1002 is fixedly connected with a piston cylinder 1003. A one-way valve is installed in the glue extraction tube 1002 so that the piston cylinder 1003 can only extract nano-imprint glue through the glue extraction tube 1002. The piston cylinder 1003 is fixedly connected in the vertical slide groove 704, and a piston plate 1004 is sealingly and slidably connected in the piston cylinder 1003. A limiting ring 1005 is fixedly connected in the piston cylinder 1003, and a magnetic plate 1006 is fixedly connected to one side of the piston plate 1004. The magnetic plate 1006 is arranged opposite to the magnetic sheet 807, and the magnetic properties of the two opposite sides are opposite. The limit ring 1005 is located on the side of the piston plate 1004 close to the magnetic plate 1006. The bottom of the piston cylinder 1003 is fixedly connected with a glue discharge pipe 1007. A one-way valve is installed in the glue discharge pipe 1007, so that the nanoimprint glue extracted from the piston cylinder 1003 can only be discharged through the glue discharge pipe 1007. The glue discharge pipe 1007 passes through the fixed plate 701 and is fixedly connected to the fixed plate 701. The glue discharge end of the glue discharge pipe 1007 is fixedly connected with a connecting hose 1008. The end of the connecting hose 1008 away from the glue discharge pipe 1007 is fixedly connected with a glue injection pipe 1009. The end of the glue injection pipe 1009 away from the connecting hose 1008 is fixedly connected with a glue coating pipe 1010. The glue coating pipe 1010 is located on both sides of the industrial camera 1104.

[0024] The servo motor 702 is started to make the bidirectional threaded rod 703 rotate forward, and the bidirectional threaded rod 703 drives the slide plate 802 to move outward through the limit screw ring 803, so that the slide plate 802 contacts and attracts the magnetic plate 1006, and the bonding part of the sheet specimen gradually moves to the support block 707. At this time, the slide plate 802 will gradually push the piston plate 1004 to slide inward along the inner wall of the piston cylinder 1003 through the magnetic plate 1006, so that the piston cylinder 1003 passes through the pump. The rubber tube 1002 draws the nanoimprint glue in the glue box 1001 until the bonding part of the sheet specimen completely falls on the supporting block 707, and the piston cylinder 1003 is filled with nanoimprint glue. At this time, the slide plate 802 stops moving, and the bonding part of the sheet specimen is located below the rubber tube 1010. After the sheet specimen is turned over by the turning mechanism 12, the rubber tube 1010 is driven by the detection mechanism 11 to move downward, and the rubber tube 1010 injects glue into the bonding part of the sheet specimen.

[0025] like Figure 3 , Figure 4 , Fig.14 and Fig.16As shown, the squeezing mechanism 9 is arranged in the detection box 1, and is used for squeezing and clamping the parts of the two sheet specimens coated with the nano-imprinting glue. The squeezing mechanism 9 is driven by the driving mechanism 7. The squeezing mechanism 9 is arranged in three groups. One group of squeezing mechanisms 9 includes a first pushing plate 901 and a second pushing plate 905. The first pushing plate 901 and the second pushing plate 905 are both slidably connected to the transverse sliding groove 706. The first pushing plate 901 and the second pushing plate 905 are both fixedly connected with a damping rod 902 on the opposite side. A limiting rod 906 is slidably connected through the first pushing plate 901 and the second pushing plate 905. The limiting rod 906 is fixedly connected in the transverse sliding groove 706. The first pushing plate 901 and the second pushing plate 905 are fixedly connected with each other. 05 is fixedly connected with an extrusion spring 903, which is sleeved on the outer surface of the damping rod 902. An extrusion plate 904 is fixedly connected with the damping rod 902. The extrusion spring 903 is fixedly connected to the extrusion plate 904. The first pushing plate 901 is fixedly connected with a second toothed rod 908 on the side close to the second pushing plate 905. The second toothed rod 908 is slidably connected to the second pushing plate 905. The second pushing plate 905 is fixedly connected with a first toothed rod 907 on the side close to the first pushing plate 901. The first toothed rod 907 is slidably connected to the first pushing plate 901. The first toothed rod 907 and the second toothed rod 908 are meshed with the first gear 705.

[0026] After the adhesive is injected on the bonding surfaces of the two sheet-like test pieces, when the flip mechanism 12 is rotated to the facing direction, the servo motor 702 is still in operation and rotation, and the slide plate 802 will continue to slide along the vertical slide groove 704 until the slide plate 802 and the vertical slide groove 704 are tightly pressed against each other. At this time, the bonding surfaces of the two sheet-like test pieces completely overlap, but there is no mutual extrusion between the two. After the nanoimprint glue coating areas of the two sheet-like specimens overlap, the bidirectional threaded rod 703 continues to rotate, which will drive the first gear 705 to rotate. At this time, since the first toothed rod 907 and the second toothed rod 908 are meshed with the first gear 705, the first toothed rod 907 and the second toothed rod 908 will move inward, and the slide 802 is limited, and the magnetic end of the limiting screw ring 803 continues to move inward away from the slide 802 until the other end of the limiting screw ring 803 contacts the slide 802. At this time, the extrusion plate 904 presses the nanoimprint glue coating areas of the two sheet-like specimens to overlap. After the two sheet-like specimens are bonded together by the nanoimprint glue, when the bidirectional threaded rod 703 rotates, it will drive the first gear 705 to rotate. At this time, since the first toothed rod 907 and the second toothed rod 908 are meshed with the first gear 705, The first tooth rod 907 and the second tooth rod 908 will move to both sides, thereby pushing the second pushing plate 905 and the first pushing plate 901 to slide to both sides along the horizontal sliding groove 706 and the limiting rod 906, so that the extrusion plate 904 cannot clamp the two sheet specimens through the extrusion spring 903. During this process, the magnetic end of the limiting screw ring 803 continues to move toward the slide plate 802, and the slide plate 802 does not slide. When the first magnetic ring 808 and the second magnetic ring 809 are attracted, the limiting screw ring 803 starts to push the slide plate 802 to slide. At this time, the extrusion plate 904 completely loses the clamping state of the two sheet specimens, so it will not affect the anti-fatigue detection quality of the nanoimprint glue under the action of shear force, thereby eliminating external interference and ensuring the anti-fatigue detection accuracy of the nanoimprint glue under the action of shear force.

[0027] like Figure 1 , Figure 2 , Figure 5 , Figure 8 , Fig.12 and Fig.13As shown, the detection mechanism 11 is fixedly connected to the middle of the detection box 1. The detection mechanism 11 is used to photograph the bonding surface shape of the nanoimprint glue and the sheet test piece after the two sheet test pieces are pulled apart. The detection mechanism 11 includes a liquid tank 1103 and a degumming chamber 1106. The glue injection pipe 1009 passes through the degumming chamber 1106 and is fixedly connected to the degumming chamber 1106. The bottom of the liquid tank 1103 is fixedly connected with an injection pipe 1105. The portion where the injection pipe 1105 is fixedly connected to the liquid tank 1103 is equipped with a pump body. The pump body is used to transport the degumming agent. A spray plate 1107 is fixedly connected in the degumming chamber 1106. The injection pipe 1105 is connected to the spray plate 1107. The bottom of the glue removal chamber 1106 is connected, and a glue scraping groove 1108 is provided, which is adapted to the sheet test piece. The detection mechanism 11 also includes an electric telescopic rod 1101 installed in the middle of the detection box 1, and the output end of the electric telescopic rod 1101 is fixedly connected to a lifting plate 1102, and three industrial cameras 1104 are installed at the bottom of the lifting plate 1102. Six third tooth rods 1109 are fixedly connected to the bottom of the lifting plate 1102, and the liquid tank 1103 is fixedly connected to the top of the lifting plate 1102. The glue removal chamber 1106 is fixedly connected to the bottom of the lifting plate 1102, and the industrial camera 1104 is located between the glue removal chambers 1106.

[0028] When the detection mechanism 11 is used for the first time for detection, the servo motor 702 is started in the reverse direction to make the bidirectional threaded rod 703 rotate in the reverse direction. At this time, the limit screw ring 803 drives the slide plate 802 to slide inward along the vertical slide groove 704 through the attraction state of the first magnetic ring 808 and the second magnetic ring 809, and pushes the sheet test piece through the scraping groove 1108. The scraping groove 1108 scrapes away the impurities on the sheet test piece, and the slide plate 802 slides inward to drive the piston plate 1004 along the piston cylinder 1003. The inner wall slides outward, so that the piston cylinder 1003 injects glue through the glue coating tube 1010 to the bonding part of the nanoimprint glue sheet specimen where impurities are scraped off, until the bonding part is fully coated. At this time, there is still no overlapping part between the two sheet specimens. At this time, the electric telescopic rod 1101 can be started to move the lifting plate 1102 upward, and then the turning mechanism 12 is driven to work through the third tooth rod 1109, so that the turntable 804 rotates, and the bonding surfaces of the two sheet specimens are rotated to the facing direction; After the bonding parts of the two sheet specimens are separated by the pulling mechanism 8, the electric telescopic rod 1101 is started to move the lifting plate 1102 downward, thereby moving the third tooth rod 1109, the adhesive removal chamber 1106 and the industrial camera 1104 downward. When the third tooth rod 1109 enters the flipping mechanism 12, the flipping mechanism 12 will be operated, thereby rotating the turntable 804, and flipping the bonding parts of the two separated sheet specimens upward, so that the industrial camera 1104 can photograph the bonding parts of the two sheet specimens. At this time, the industrial camera 1104 photographs the bonding parts of the two sheet specimens and the nanoimprint adhesive to determine the bonding parts of the two sheet specimens. The bonding area between the two sheet specimens and the nanoimprint adhesive is measured without removing the two separated sheet specimens to measure the bonding area separately, which reduces the burden on personnel and improves the efficiency of fatigue resistance detection of the nanoimprint adhesive. Then, the servo motor 702 is started again to rotate the bidirectional threaded rod 703, and then the slide plate 802 is driven to slide outward along the vertical slide groove 704 through the limit screw ring 803, and then the flipped sheet specimen is driven to slide outward through the electric clamping plate 805, so that the bonding parts of the two sheet specimens fall on the supporting block 707, and then the electric telescopic rod 1101 is started again to make the glue removal chamber 1106 fall on the supporting block 707 through the lifting plate 1102. At this time, the sheet specimen is The bonding part between the sheet-like specimen and the nano-imprint adhesive is in the adhesive removal chamber 1106 and in the adhesive scraping groove 1108, and then the pump body can be started to extract the adhesive remover in the liquid tank 1103, and then the adhesive remover is transported to the spray plate 1107 through the injection pipe 1105, and sprayed on the bonding part between the sheet-like specimen and the nano-imprint adhesive through the spray plate 1107. After standing for a period of time, the servo motor 702 is started in the reverse direction to make the bidirectional threaded rod 703 rotate in the reverse direction. At this time, since the limiting screw ring 803 and the slide plate 802 are attracted by the first magnetic ring 808 and the second magnetic ring 809, the slide plate 802 will be driven to slide inward along the vertical slide groove 704, pushing the sheet-like specimen. The sheet specimen passes through the scraping groove 1108, and the scraping groove 1108 scrapes off the nano-imprint adhesive dissolved by the adhesive remover on the sheet specimen. After the bonding part of the sheet specimen completely passes through the scraping groove 1108, there is still no overlapping part between the two sheet specimens. At this time, the electric telescopic rod 1101 can be started to move the lifting plate 1102 upward, and then the third tooth rod 1109 drives the flip mechanism 12 to work, so that the turntable 804 rotates, and the bonding surfaces of the two sheet specimens are rotated to the facing direction until the electric telescopic rod 1101 is completely retracted, thereby realizing the automatic adhesive removal operation, reducing the burden on personnel, and further improving the efficiency of the anti-fatigue detection of the nano-imprint adhesive; like Figure 2 , Fig. 9 , Fig.11 , Fig.12 , Fig.14 , Fig.15 and Fig.16As shown, the flip mechanism 12 is installed in the driving mechanism 7, and the flip mechanism 12 is driven by the detection mechanism 11 to change the position of the pulling mechanism 8. The flip mechanism 12 includes a first synchronous wheel 1201 fixedly connected to the outer surface of the rotating disk 804, a fixed frame 1203 is fixedly connected to one side of the pulling block 801, and a second synchronous wheel 1204 is rotatably connected to one side of the fixed frame 1203. The first synchronous wheel 1201 is connected to the second synchronous wheel 1204 through a synchronous belt 1202, and a rotating rod is slidably connected inside the second synchronous wheel 1204. 1206, one end of the rotating rod 1206 is fixedly connected to the second gear 1205, the second gear 1205 is meshed with the third tooth rod 1109, the number of teeth of the third tooth rod 1109 is one quarter of the number of teeth of the second gear 1205, a movable groove 1207 is opened on the fixed plate 701, the other end of the rotating rod 1206 is rotatably connected to the movable groove 1207, the third tooth rod 1109 is adapted to the movable groove 1207, and the end of the second gear 1205 away from the rotating rod 1206 is rotatably connected to the movable groove 1207.

[0029] When the slide plate 802 slides in the vertical slide groove 704, the fixing frame 1203 will be driven to move through the pulling block 801. At this time, the fixing frame 1203 will drive the second synchronous wheel 1204 to slide along the outer surface of the rotating rod 1206. When the third tooth rod 1109 moves downward into the movable groove 1207 and meshes with the second gear 1205, the third tooth rod 1109 continues to move downward, which will drive the second gear 1205 to rotate. Since the number of teeth of the third tooth rod 1109 is one fourth of the number of teeth of the second gear 1205, the second gear 1205 can only rotate ninety degrees. It will drive the rotating rod 1206 to rotate, and then drive the second synchronous wheel 1204 to rotate, so that the second synchronous wheel 1204 drives the first synchronous wheel 1201 to rotate ninety degrees through the synchronous belt 1202. At this time, the first synchronous wheel 1201 will drive the turntable 804 to rotate ninety degrees, so that the two sheet specimens are rotated ninety degrees, so that the bonding surfaces of the two sheet specimens are in an upward state, and in the process of the third tooth rod 1109 being pulled out of the movable groove 1207, the third tooth rod 1109 will still drive the second gear 1205 to rotate ninety degrees in the opposite direction, so that the two sheet specimens are flipped ninety degrees, so that the bonding surfaces of the two sheet specimens are in a facing state.

[0030] The specific working principle of the present invention is as follows: when in use, open the box door 2 and place two sheet specimens on two supporting plates 806 in a group of pulling mechanisms 8 respectively. At this time, the electric clamping plate 805 can be started to clamp and fix the sheet specimens. The bonding surfaces of the two sheet specimens are within the area where the supporting block 707 is located. At this time, the glue injection mechanism 10 is full of nano-imprint glue, and then the box door 2 is closed and the electric telescopic rod 1101 is started to make the lifting plate 1102 move downward, thereby making the third tooth rod 1109, the glue removal chamber 1106 and the industrial camera 1104 move downward. When the third tooth rod 1109 moves downward into the movable groove 1207 and meshes with the second gear 1205, the third tooth rod 1109 moves downward into the movable groove 1207 and meshes with the second gear 1205. The continued downward movement of the three-tooth rod 1109 will drive the second gear 1205 to rotate. Since the number of teeth on the third-tooth rod 1109 is one fourth of the number of teeth on the second gear 1205, the second gear 1205 can only rotate ninety degrees. When the second gear 1205 rotates ninety degrees, it will drive the rotating rod 1206 to rotate, and then drive the second synchronous wheel 1204 to rotate, so that the second synchronous wheel 1204 drives the first synchronous wheel 1201 to rotate ninety degrees through the synchronous belt 1202. At this time, the first synchronous wheel 1201 will drive the rotating disk 804 to rotate ninety degrees, so that the two sheet specimens rotate ninety degrees, so that the bonding surfaces of the two sheet specimens are facing The electric telescopic rod 1101 continues to drive the degumming chamber 1106 to move downward through the lifting plate 1102, so that the bonding part of the sheet specimen and the nanoimprint adhesive is in the degumming chamber 1106 and in the scraping glue groove 1108. Then the servo motor 702 is started to reverse, driving the bidirectional threaded rod 703 to rotate, so that the slide plate 802 moves inward under the action of the limiting screw ring 803 through the magnetic attraction of the first magnetic ring 808 and the second magnetic ring 809, and pushes the sheet specimen through the scraping glue groove 1108. The scraping glue groove 1108 scrapes off the impurities on the sheet specimen. At this time, the slide plate 802 moves inward and And because the slide plate 802 is attracted to the magnetic plate 1006 through the magnetic sheet 807, the piston plate 1004 will be pulled to slide outward along the inner wall of the piston cylinder 1003, so that the nano-imprint glue in the piston cylinder 1003 enters the glue discharge pipe 1007, and then is discharged into the glue coating pipe 1010 through the connecting hose 1008 and the glue injection pipe 1009, and is gradually discharged from the glue coating pipe 1010 to the bonding surface of the sheet test piece until the piston plate 1004 slides to the position of the limit ring 1005. At this time, the bonding surface of the sheet test piece completely passes through the glue scraping groove 1108, realizing the automatic glue injection operation, reducing the burden on personnel, and further improving the efficiency of the fatigue resistance detection of the nano-imprint glue; After the bonding part of the sheet specimens completely passes through the scraping groove 1108, the bonding surfaces of the two sheet specimens are coated with nano-imprint glue, but there is no overlapping part of the two sheet specimens. At this time, the electric telescopic rod 1101 can be started to move the lifting plate 1102 upward, thereby driving the third tooth rod 1109 to move upward. In the process of the third tooth rod 1109 being withdrawn from the movable groove 1207, the third tooth rod 1109 will still drive the second gear 1205 to rotate 90 degrees in the opposite direction, thereby turning the two sheet specimens over 90 degrees, so that the bonding surfaces of the two sheet specimens re-coated with nano-imprint glue are in a facing state, and the turntable 804 is rotated to rotate the bonding surfaces of the two sheet specimens to the facing direction until the electric telescopic rod 1101 is completely retracted; When the bonding surfaces of the two sheet specimens rotate to the facing direction, the servo motor 702 drives the slide plate 802 to slide inward along the vertical slide groove 704 until the slide plate 802 and the vertical slide groove 704 are tightly pressed against each other. At this time, the bonding surfaces of the two sheet specimens completely overlap, but there is no mutual extrusion between the two. When the two-way threaded rod 703 rotates during this process, it will drive the first gear 705 to rotate, thereby causing the first toothed rod 907 and the second toothed rod 908 to move inward, thereby pulling the second pushing plate 905 and the first pushing plate 901 to slide inward along the horizontal sliding groove 706 and the limiting rod 906. At this time, the damping rod 902, the extrusion plate 904 and the extrusion spring 903 will move toward the two sheet-like test pieces. When the slide plate 802 is not tightly against the vertical sliding groove 704, the extrusion plate 904 is not in contact with the two sheet-like test pieces. When the slide plate 802 is tightly against the vertical sliding groove 704, the setting of the first magnetic ring 808 and the second magnetic ring 809 will enable the two-way threaded rod 703 to continue to rotate, causing the limiting screw ring 803 to move inward, and the first The magnetic ring 808 and the second magnetic ring 809 are disengaged, and the slide plate 802 is disengaged. During this process, the second pushing plate 905 and the first pushing plate 901 will continue to move inward until the end of the limiting screw ring 803 without the first magnetic ring 808 is in contact with the slide plate 802. At this time, the squeezing plate 904 will clamp the bonding parts of the two sheet specimens through the squeezing spring 903 and the damping rod 902, thereby ensuring the firmness of the bonding surfaces of the two sheet specimens through the nano-imprint adhesive, facilitating the subsequent anti-fatigue test of the nano-imprint adhesive in different environments, so that personnel can perform anti-fatigue test of the nano-imprint adhesive without replacing the sheet specimen, reducing the burden on personnel and improving the test efficiency. In addition, the two sheet specimens can be reused, saving resources. After the two sheet specimens are firmly attached by the nano-imprinting adhesive under the extrusion of the extrusion plate 904, the servo motor 702 can be started to make the bidirectional threaded rod 703 rotate forward. At this time, since the limiting screw ring 803 is connected to the bidirectional threaded rod 703 through threads, and the first magnetic ring 808 is not in contact with the second magnetic ring 809, the limiting screw ring 803 will slide outward relative to the slide plate 802 under the rotation of the bidirectional threaded rod 703. At the same time, when the bidirectional threaded rod 703 rotates, it will drive the first gear 705 to rotate. The first tooth rod 907 and the second tooth rod 908 are meshed with the first gear 705, which will cause the first tooth rod 907 and the second tooth rod 908 to move to the sides, thereby pushing the second pushing plate 905 and the first pushing plate 901 to slide to the sides along the horizontal sliding groove 706 and the limiting rod 906, so that the extrusion plate 904 cannot clamp the two sheet test pieces through the extrusion spring 903. During this process, the slide plate 802 does not slide until the limiting screw ring 803 and the slide plate 802 are connected through the first magnetic ring 808 and the second magnetic ring 809. The limiting screw ring 803 will drive the slide plate 802 to slide outward along the vertical slide groove 704. During the sliding process of the slide plate 802 in the vertical slide groove 704, the fixing frame 1203 will be driven to move through the pulling block 801. At this time, the fixing frame 1203 will drive the second synchronous wheel 1204 to slide along the outer surface of the rotating rod 1206. At this time, the extrusion plate 904 completely loses the clamping state of the two sheet specimens, so it will not affect the anti-fatigue detection quality of the nano-imprint glue under the action of shear force, thereby eliminating external interference and ensuring the nano-imprint glue. The fatigue resistance test accuracy of the nano-imprint adhesive under the action of shear force is measured, and then the two sheet specimens are pulled to the two ends by the electric clamp 805, so that the nano-imprint adhesive bonded between the two sheet specimens is subjected to shear force until the bonding parts of the two sheet specimens are pulled apart. At this time, the servo motor 702 can be turned off. In this process, the state of the two sheet specimens bonded by the nano-imprint adhesive is continuously photographed by the industrial camera 1104. When the bonding parts of the two sheet specimens to be bonded are separated under the action of tension, the value detected by the tension sensor at this time is recorded; The electric telescopic rod 1101 is started to move the lifting plate 1102 downward, thereby moving the third tooth rod 1109, the degumming chamber 1106 and the industrial camera 1104 downward. When the third tooth rod 1109 moves downward into the movable groove 1207 and meshes with the second gear 1205, the continued downward movement of the third tooth rod 1109 will drive the second gear 1205 to rotate. Since the number of teeth of the third tooth rod 1109 is one fourth of the number of teeth of the second gear 1205, the second gear 1205 can only rotate ninety degrees. When the second gear 1205 rotates ninety degrees, it will drive the rotating rod 1206 to rotate, thereby driving the second synchronous wheel 1204 to rotate, so that the second synchronous wheel 1204 drives the first synchronous wheel 1201 to rotate ninety degrees through the synchronous belt 1202. At this time, the first synchronous wheel 1 201 will drive the turntable 804 to rotate 90 degrees, thereby rotating the two sheet specimens 90 degrees, so that the bonding surfaces of the two sheet specimens are in an upward state, so that the industrial camera 1104 can photograph the bonding parts of the two sheet specimens. At this time, the industrial camera 1104 photographs the bonding parts of the two sheet specimens and the nanoimprint adhesive to determine the bonding areas of the two sheet specimens and the nanoimprint adhesive. There is no need to remove the two separated sheet specimens to measure the bonding areas separately, which reduces the burden on personnel and improves the efficiency of fatigue resistance detection of the nanoimprint adhesive. Then, according to the value detected by the tension sensor when the bonding parts of the two bonded sheet specimens are separated under tension, combined with the bonding areas of the nanoimprint adhesive on the two sheet specimens photographed by the industrial camera 1104, the fatigue resistance of the nanoimprint adhesive under the action of shear force is calculated; After the calculation is completed, the servo motor 702 is started again to make the bidirectional threaded rod 703 rotate forward, and then the slide plate 802 is driven to slide outward along the vertical slide groove 704 through the limiting screw ring 803, and then the two flipped sheet specimens are driven to slide outward through the electric clamping plate 805, so that the bonding part of the sheet specimen falls on the supporting block 707, and then the electric telescopic rod 1101 is started again to drive the lifting plate 1102 to continue to descend so that the degumming chamber 1106 falls on the supporting block 707. At this time, the bonding part between the sheet specimen and the nanoimprint glue is in the degumming chamber 1106 and in the scraping glue groove 1108, and then the pump body can be started to extract the degumming agent in the liquid tank 1103, and then the degumming agent is transported to the spray plate 1107 through the injection pipe 1105, and sprayed on the bonding part between the sheet specimen and the nanoimprint glue through the spray plate 1107. After standing for a period of time, the electric telescopic rod 1101 can be started. 01, so that the lifting plate 1102 moves upward to the highest position, and the third tooth rod 1109 moves upward under the drive of the lifting plate 1102, which will drive the second gear 1205 to rotate. Since the number of teeth of the third tooth rod 1109 is one fourth of the number of teeth of the second gear 1205, the second gear 1205 can only rotate ninety degrees, and when the second gear 1205 rotates ninety degrees, it will drive the rotating rod 1206 to rotate, and then drive the second synchronous wheel 1204 to rotate, so that the second synchronous wheel 1204 drives the first synchronous wheel 1201 to rotate ninety degrees through the synchronous belt 1202. At this time, the first synchronous wheel 1201 will drive the turntable 804 to rotate ninety degrees, so that the two sheet specimens rotate ninety degrees, so that the two sheet specimens are in a vertical state, and at this time, the electric clamping plate 805 can be started so that the electric clamping plate 805 cannot clamp the sheet specimen, and then the sheet specimen can be removed; Furthermore, the temperature and humidity inside the detection box 1 can be adjusted by the heat exchanger 5 and the humidifier to simulate the bonding strength of the nanoimprint adhesive at different temperatures and humidities, thereby making the obtained anti-fatigue performance of the nanoimprint adhesive more accurate and more convincing.

[0031] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
