A feeding component 4 is fixedly installed on the top of the rotating component 3. The rotating component 3 includes a rotating shaft 31 and a grooved wheel 32. The rotating shaft 31 is connected to the top of the base plate 1 via a bearing. The grooved wheel 32 is fixedly connected to the side wall of the rotating shaft 31. A motor 33 is fixedly installed on the top of the base plate 1. A rotating block 34 is fixedly connected to the output end of the motor 33. The bottom of the rotating block 34 is fixedly... A connecting rod 35 is fixedly installed, and a sliding rod 36 is fixedly installed on the top of the connecting rod 35. The sliding rod 36 is slidably connected to the grooved wheel 32. A rotating frame 37 is fixedly connected to the top of the rotating shaft 31. The detection assembly 2 includes a support frame 21 and an electric heating wire 22. The support frame 21 is fixedly installed on the top of the base plate 1, and the electric heating wire 22 is located on the top of the support frame 21.

The support frame 23 is fixedly installed on the top of the base plate 1, and the temperature detector 24 is fixedly installed on the bottom of the support frame 23.

[0033] In this embodiment, the motor 33 is then turned on, which drives the rotating block 34 to rotate the grooved wheel 32 through the connecting rod 35 and the slide rod 36. This allows the grooved wheel 32 to rotate the rotating frame 37 by using the rotating shaft 31, making the overall stepping rotation more convenient. Finally, the temperature detector 24 is turned on to detect the temperature of the thermal conductive adhesive to test whether it is qualified.

[0034] Reference Figures 1 to 4 In one aspect of this embodiment, the feeding assembly 4 includes a second motor 41 and a threaded rod 42. The second motor 41 is fixedly installed on the top of the rotating frame 37. The threaded rod 42 is fixedly connected to the output end of the second motor 41. A lifting block 43 is threadedly connected to the side wall of the threaded rod 42. A connecting rod 44 is hinged to the side wall of the lifting block 43.

At the same time, the lifting block 43 will drive the slide plate 45 through the connecting rod 44 to slide inside the stabilizing plate 46 using the slider 47, so that the slide plate 45 can push the thermal conductive adhesive. Then, the electric heating wire 22 is turned on to heat the thermal conductive adhesive.

[0036] Working principle: First, the thermal conductive adhesive is placed on the top of the rotating frame 37. Then, the motor 41 is started, which drives the threaded rod 42 to rotate. The threaded rod 42 drives the lifting block 43 to move downward. At the same time, the lifting block 43 drives the slide plate 45 through the connecting rod 44. The slide plate 47 slides inside the stabilizing plate 46, so that the slide plate 45 can push the thermal conductive adhesive. Then, the electric heating wire 22 is turned on to heat the thermal conductive adhesive.

[0037] Then, turning on motor 33 can drive rotating block 34 to drive grooved wheel 32 to rotate through connecting rod 35 and slide rod 36, so that grooved wheel 32 can drive rotating frame 37 to rotate 90 degrees through rotating shaft 31, making the overall stepping rotation more convenient. Finally, turning on temperature detector 24 can detect the temperature of thermal conductive adhesive to test whether it is qualified.
