Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a peel test device for a heat shrink tape installation system, comprising:

[0022] Support frame 1, on which mounting plate 2 is installed; mounting plate 2 is fixed to support frame 1 by bolts or welding to ensure a stable connection between the two.

[0023] The peeling test assembly includes a first U-shaped plate 7 fixed on the mounting plate 2. A first clamping plate 8 for fixing a steel plate slides on the first U-shaped plate 7. A first screw 9 is rotatably connected to the upper end of the first clamping plate 8. The first screw 9 passes through the first U-shaped plate 7 and is threaded to it. A first handle 10 is fixedly connected to the upper end of the first screw 9. Rotating the first handle 10 drives the first screw 9 to rotate, thereby driving the first clamping plate 8 to move downward. The steel plate with heat shrink tape is placed on the mounting plate 2 and located below the first clamping plate 8. The first clamping plate 8 moves downward to clamp the steel plate, thereby achieving the positioning of the steel plate.

[0024] The treatment of the steel plate and heat shrinkable tape includes a heat shrinkable tape installation mechanism. This mechanism comprises a bracket 5 rotatably mounted on a movable frame 15. The bracket 5 is connected to the movable frame 15 via a damping shaft. The damping strength of the damping shaft can support the weight of the bracket 5 and the hot air blower 6, allowing adjustment of the position of the hot air blower 6 to avoid affecting subsequent experimental operations. The hot air blower 6 is fixed on the bracket 5. Moving the movable frame 15 can move the bracket 5 and the hot air blower 6, thereby heating the heat shrinkable tape. Specifically, the steel plate sample is cleaned and polished to ensure it is free of oil, rust, etc. The heat shrinkable tape is installed according to the manufacturer's requirements, ensuring complete coverage and heating to the specified temperature to allow it to fully shrink and bond. Curing is then performed according to the product instructions, typically requiring 24 hours. This completes the treatment of the steel plate and heat shrinkable tape. The sample can then be placed without disassembly, and a peel test is conducted after 24 hours.

[0025] A second U-shaped plate 11 is slidably connected to the mounting plate 2. A tension sensor 20 is mounted on the second U-shaped plate 11. The tension sensor 20 is a resistance strain gauge type tension sensor, and its specific model can be selected according to the requirements. An industrial control computer 4 is mounted on the mounting plate 2. The industrial control computer 4 is connected to the tension sensor 20. The tension sensor 20 is connected to the industrial control computer 4 through a transmission line, and the detected data can be displayed on the industrial control computer 4.

[0026] A third U-shaped plate 12 is fixed to the tension sensor 20. A support plate 16 is fixed inside the third U-shaped plate 12. A second clamping plate 17 for clamping heat shrink tape is slidably connected inside the third U-shaped plate 12. A second screw 18 is rotatably connected to the upper end of the second clamping plate 17. The second screw 18 passes through the third U-shaped plate 12 and is threaded to it. A second handle 19 is fixedly connected to the upper end of the second screw 18. Figure 2As shown, the heat shrink tape near the first U-shaped plate 7 is pulled up and placed between the support plate 16 and the second clamping plate 17. The second handle 19 is rotated to drive the second screw 18 to rotate. The rotation of the second screw 18 causes the second clamping plate 17 to move down. The second clamping plate 17 moves down to clamp and position the heat shrink tape.

[0027] Two positioning plates 22 are fixedly connected to the bottom of the mounting plate 2. Guide rails 21 are fixed on the two positioning plates 22. A motor 13 is mounted on one of the positioning plates 22. A lead screw 14 is fixedly connected to the output end of the motor 13. The end of the lead screw 14 is rotatably connected to the other positioning plate 22. A movable frame 15 is connected to the guide rail 21. A guide block for use with the guide rail 21 is fixed on the movable frame 15. The lead screw 14 passes through the movable frame 15 and is threaded to it. Two strip grooves 3 are provided through the mounting plate 2. The movable frame 15 passes through the strip grooves 3 and is fixedly connected to the second U-shaped plate 11. The operation of the motor 13 drives the lead screw 14 to rotate, which in turn drives the movable frame 15 to move. The movement of the movable frame 15 drives the second U-shaped plate 11 to move (moving away from the first U-shaped plate 7). Driven by the tension sensor 20, the second U-shaped plate 12 moves, which in turn drives the heat shrink tape to move. The heat shrink tape moves and separates from the steel plate with resistance. The tension sensor 20 can detect the value when peeling, and can understand the bonding strength between the heat shrink tape and the steel plate.

[0028] Record the maximum peel force and peel strength (peel force divided by adhesive width) during the peeling process. The peel strength is calculated as: peel strength = maximum peel force / adhesive width. Compare the results with relevant standards (such as ISO 21809-3) or manufacturer requirements to determine whether they are qualified.

[0029] In summary, this utility model integrates the installation and peel test of heat shrink tape into one process, eliminating the need for multiple disassembly and fixing of the steel plate. This facilitates the peel test of the heat shrink tape, and the fixing of the steel plate and heat shrink tape is simple, quick, and stable, providing convenience for operators.
