In the prior art, a large number of medicine component detection and corresponding devices are also disclosed, for more accurate comparison, for example, chinese patent publication No. CN209400284U discloses a medicine detection device, which comprises a box body and a medicine component detector therein, wherein the box body comprises a medicine placing plate, a telescopic device positioned at the bottom of the medicine placing plate, and a grinding device positioned at the top of the medicine placing plate; a medicine placing cavity is arranged in the medicine placing plate; the medicine component detector is fixedly arranged at the top of the box body and is positioned at one side of the grinding device; in addition, the box body is also provided with a box door, the box door is hinged with the box body through a hinge, and the box door is provided with a see-through area and a handle.
When the medicine to be detected is placed in the medicine placement cavity, the medicine placement plate is controlled to move upwards rapidly so that the grinding head enters the medicine placement cavity and is impacted, and therefore the medicine to be detected is crashed; then the rotating motor is used for controlling the rotating shaft to rotate so as to drive the grinding head to rotate in the medicine placing cavity, so that the medicine to be measured is ground more fully and uniformly; and then controlling the medicine placing plate to move to the position right below the medicine component detector, and carrying out component analysis on the ground medicine to be detected through the medicine component detector.
However, in the process of detecting components of a drug using the above-described prior art, there are the following disadvantages:

2. Since a certain amount of medicine is required to be taken for detection when the medicine is subjected to component detection, the content of medicine components can be detected, and when the medicine detection device detects the ground medicine through the medicine component detector, the medicine cannot be quantitatively detected, so that the content of the medicine components cannot be accurately detected.
