[0029] In some embodiments of the utility model, a lifting rod 25 is symmetrically provided on the top of the upper detection plate 22, and the other end of the lifting rod 25 passes through the support plate 12. The setting of the lifting rod 25 can limit the upper detection plate 22 when it moves up and down, so that when testing the viscosity of the adhesive, pulling upward can be smoother, which is conducive to the accuracy of the detection.

[0030] The detection frame 10 also includes a feeding mechanism 30 and an angle adjustment mechanism 40. The feeding mechanism 30 includes a rotating plate 31. A second hydraulic cylinder 32 is installed on the rotating plate 31. The output shaft of the second hydraulic cylinder 32 is connected to the lower detection plate 33. Two parallel slide rails 35 are also provided on the rotating plate 31. A sliding sleeve 36 is provided at the bottom of the lower detection plate 33. The sliding sleeve 36 cooperates with the sliding rail 35. One side of the lower detection plate 33 is connected to the output shaft of the second hydraulic cylinder 32.

[0031] In some embodiments of the present invention, a rectangular groove 15 is provided on the top of the support seat 11 , and the rotating plate 31 is installed in the rectangular groove 15 .

[0032] By utilizing the sliding sleeve 36 and the slide rail 35 to slide together, the output shaft of the second hydraulic cylinder 32 can be more flexible in driving the movement of the lower detection plate 33, and the two slide rails 34 can stably support the lower detection plate 33, the structure is more compact, and the adhesive lower detection plate 33 can be automatically moved to the bottom of the upper detection plate 22, avoiding the inspection personnel to extend their hands to work under the upper detection plate 22, which not only causes inconvenience to the inspection, but also the machine may cause accidental injury to the inspection personnel.

The test data not only includes vertical detection, but also test data at a certain tilt angle, which makes the detection of the adhesive more comprehensive and diverse, and is conducive to the accuracy of the adhesive test data.
