[0010] Beneficial effects:

[0011] 1. The modified epoxy adhesive stretch peel tester can be driven by a servo motor to drive the transmission screw, the fixing frame, the tension sensor, the second fixing sleeve and the test plate to move along the axial direction of the transmission screw through the cooperation of the transmission disk and the transmission screw, and then perform a stretch peeling operation on the test plate located inside the first clamp and the second clamp.

The tension sensor 10 is provided with a second fixing sleeve 11 fixedly mounted on the bottom of the tension sensor 10, and a second fixture 12 is fixedly mounted inside the bottom of the second fixing sleeve 11, and the second fixture 12 can be easily disassembled and assembled through the second fixing sleeve 11. A test plate 13 located inside the first fixture 7 is fixedly mounted on the inner side of the second fixture 12, and the upper and lower plates of the test plate 13 are vertically distributed, and the modified epoxy adhesive is distributed between the upper and lower plates. A transmission mechanism 14 fixedly mounted inside the fixing frame 8 is movably sleeved inside the first fixing plate 9, and a driving mechanism 15 electrically connected to the console 5 is fixedly mounted in the middle of the top of the first fixing plate 9.

[0023] Among them, the transmission mechanism 14 includes a first limiting rod 141 and a second limiting rod 142, the top end of which is movably sleeved inside the first fixing plate 9 and the bottom end of which is fixedly sleeved inside the fixing frame 8. The first limiting rod 141 and the second limiting rod 142 extend out of the top outer side of the first fixing plate 9 and are jointly fixedly sleeved with a second fixing plate 143. The middle part of the second fixing plate 143 is internally fixedly sleeved with a transmission screw 144 located on the inner side of the first fixing plate 9 and the bottom end of which is movably sleeved inside the top of the fixing frame 8. The transmission screw 144 extends to the bottom outer side of the inner side of the fixing frame 8 and is threadedly sleeved with a nut 145. Through the coordinated use of the first limiting rod 141, the second limiting rod 142, the second fixing plate 143 and the nut 145, the tester can limit and fix the transmission screw 144 while ensuring that the transmission screw 144 can be distributed in the center.

[0024] Among them, the driving mechanism 15 includes a slewing bearing 151 fixedly installed in the middle of the top of the first fixed plate 9 and located on the outside of the transmission screw 144, and a servo motor 152 fixedly sleeved inside the first fixed plate 9. A transmission disk 153 threadedly sleeved on the outside of the transmission screw 144 is fixedly installed on the top of the slewing bearing 151, and a gear 154 meshing with the outer edge of the slewing bearing 151 is fixedly sleeved on the outside of the output shaft of the servo motor 152. The servo motor 152 can drive the slewing bearing 151 and the transmission disk 153 to rotate while driving the transmission screw 144 and the fixed frame 8 to move. The distance sensor 4 can detect the distance after the fixed frame 8 moves, so as to control the drive of the servo motor 152, and at the same time, the second clamp 12 can be quickly moved to the initially set position.

[0025] Among them, the outer side of the transmission screw 144 is provided with a limit plate 16 located above the fixed frame 8 and a limit column 17 arranged on both sides of the top of the fixed frame 8 and movably connected to the inside of the limit plate 16.

The pressing plate 128 can drive the pressing plate 128 to press and fix the test plate 13 placed on the inner side of the third slide plate 122 and the fourth slide plate 123 by rotating the bolt 127. At the same time, during the stretching and peeling operation of the tester, the upper plate of the test plate 13 can be pulled by the third slide plate 122 and the fourth slide plate 123, and after the upper plate is separated from the lower plate, the upper plate can be stably fixed on the third slide plate 122 and the fourth slide plate 123. In addition to its own gravity, the upper plate will not generate any additional force on the third slide plate 122 and the fourth slide plate 123, ensuring that the tester can accurately measure the peeling force of the modified epoxy adhesive through the tension sensor 10.

[0027] Among them, the first clamp 7 includes a first slide seat 71 fixedly sleeved inside the first fixed sleeve 6, and the outer side of the top of the first slide seat 71 is slidably connected with a first slide plate 72 and a second slide plate 73 located on the outer side of the test plate 13, and the first slide plate 72 and the second slide plate 73 are commonly threadedly sleeved with a first bidirectional screw rod 74 rotatably connected to the inside of the first slide seat 71. The first slide plate 72 and the second slide plate 73 can limit the lower plate of the test plate 13, but will not fix the lower plate, and then after the upper plate is fixed on the inner side of the second clamp 12, the lower plate will not contact the first slide plate 72 and the second slide plate 73, and sufficient space can be reserved to press and fix the upper plate, and in this process, the upper and lower parts will not be pulled, so that the first slide plate 72 and the second slide plate 73 will not generate additional force on the lower plate.

[0028] When the tester is in use, the servo motor 152 is started by the console 5 to drive the adjustment of the distance between the first clamp 7 and the second clamp 12, and then the distance between the third slide 122 and the fourth slide 123 is adjusted by rotating the second bidirectional screw rod 124, and the test plate 13 is placed between the third slide 122 and the fourth slide 123, and the second bidirectional screw rod 124 is rotated in the opposite direction to move the third slide 122 and the fourth slide 123 to the outside of the test plate 13, and the pressing plate 128 is driven by rotating the bolt 127 to press and fix the upper plate of the test plate 13, and the first bidirectional screw rod 74 is rotated to move the first slide 72 and the second slide 73 to the outside of the lower plate of the test plate 13. At this time, the lower plate is not It will contact the first slide 72 and the second slide 73, and the servo motor 152 is started by the control console 5 to rotate in the opposite direction while driving the second clamp 12 to move upward, and the test plate 13 is driven to move upward synchronously by the third slide 122 and the fourth slide 123. When the lower plate of the test plate 13 contacts the first slide 72 and the second slide 73, a pulling force will be generated on the upper and lower plates, and the generated pulling force will be measured by the tension sensor 10. After the upper and lower plates are completely separated, when the tension sensor 10 detects that the tension is 0, the servo motor 152 is automatically turned off to complete the measurement of the peeling force of the modified epoxy adhesive.
