[0042] Furthermore, the first clamping body and the second clamping body are jointly arranged on the rotating plate 302, and the rotating plate 302 is rotatably connected to the workbench 101. A driving motor for controlling the rotation of the rotating plate 302 is arranged on the workbench 101.

[0046] Operation process: During the inspection, the operator controls the first grabbing member 102 and the second grabbing member 103 to adjust the spacing between the two grabbing blocks 102a to the selected cutting length, and then uses the control arm 101a at the rear end to push the two grabbing blocks 102a to a position close to the tape roll. At this time, the tape roll has been pulled out part of the length through the structure. At this time, the two grabbing blocks 102a are pushed to the tape roll, and then the grabbing plate 102b is rotated, and the pressure rod 102c on the grabbing plate 102b is used to pierce the tape roll, and the pressure knife 102d is used to cut off the two ends of the tape, and then the tape is adsorbed by vacuum adsorption through the vacuum adsorption tube 104 to complete the cutting and grabbing of the tape segment.

[0047] Then the grabbing plate 102b is rotated upward, and the angle of the control arm 101a is adjusted so that the surface of the grabbing plate 102b is parallel to the upper surfaces of the clamping block 201a and the matching body 202a, and then the first grabbing member 102 and the second grabbing member 103 are pushed so that the two grabbing blocks 102a are respectively in contact with the clamping block 201a and the matching body 202a. At this time, the vacuum adsorption tube 104 stops vacuum adsorption and uses the adhesive layer 201c to adhere the two ends of the tape segment to the clamping block 201a and the matching body 202a. At this time, the slider 202b is started to slide, thereby applying shear force to the tape segment, and then the monitoring module 204 is used to monitor the static shear force of the current tape.

The detachable component 400 separates the fitting body 202a from the slider 202b. At this time, the fitting body 202a falls freely, and the shear force at this time is detected.
