s3: inputting the daily dose and the administration time interval of each medicine into a controller;
s4: the controller takes and divides the medicines according to the medicines to be taken and the dose of each medicine within the taking time period, and the method specifically comprises the following steps:
s41: the controller drives the turntable to rotate so that a medicine storage tube mechanism where a required medicine is located rotates to a radial outer corresponding position of the push piece or the concave arc-shaped push head and stops, specifically, the push piece or the concave arc-shaped push head is rotated to the push piece corresponding position when the bottom surface of the medicine is a plane according to the shape of the bottom surface of the medicine, the concave arc-shaped push head corresponding position is rotated when the bottom surface of the medicine is an arc, when the bottom surface of the medicine cannot be determined to correspond to the push piece or the concave arc-shaped push head, the medicine is respectively rotated to the push piece and the concave arc-shaped push head corresponding position, the medicine can be pushed out at the position according to the following S42 step operation, and the medicine can be determined to be rotated to the pushed out corresponding position;
s42, the linear driving mechanism drives the corresponding medicine taking and distributing driving rod to move outwards the fixed disc, in the moving process, the two sides of the U shape contact with ears and then upwards lift the ears to drive the floating medicine bin pipe to ascend, the vertical spring is compressed in the ascending process, the pushing piece or the concave arc-shaped pushing head is stopped after contacting with the floating medicine bin pipe, when the medicine taking and distributing driving rod moves outwards the fixed disc again, the horizontal spring is compressed, the pressure sensor senses a pressure signal, the lowermost medicine is exposed in the ascending process of the floating medicine bin pipe, the pushing piece or the concave arc-shaped pushing head is propped against the lowermost medicine, when the thickness of the lowermost medicine is larger than the gap formed between the floating medicine bin pipe and the fixed disc, the lowermost medicine is propped against the pushing piece or the concave arc-shaped pushing head between the inner wall of the floating medicine bin pipe, the linear driving device drives the medicine taking and distributing driving rod to enable the floating medicine bin pipe to continuously ascend, when the thickness of the lowermost medicine is smaller than the gap formed between the floating medicine bin pipe and the fixed disc, the lowermost medicine is pushed out from the inner wall of the arc-shaped pushing rod to the bottom of the corresponding medicine box under the action of the horizontal spring, the pressure sensor senses the pressure signal, and pushes the lowermost medicine box to push the second medicine box;
s43: the linear driving mechanism drives the corresponding medicine taking and distributing driving rod to move towards the fixed disc, and when the medicine which is the same as the previous medicine needs to be taken continuously, the step S42 is repeated; when another medicine needs to be taken and distributed, S41 and S42 are executed in sequence; until the medicines to be taken in the time period are measured according to the required number, all the medicines to be taken in the time period enter the medicine collecting box.
10. The automated drug dispensing method of claim 9, wherein: when the number of the medicines in one medicine bin pipe mechanism is equal to the number of the medicines taken out, and the medicines cannot be detected by the medicine detection sensor at the same time, the controller sends a prompt to supplement the medicines into the medicine bin pipe mechanism; when the medicine is taken and distributed, if the horizontal spring is popped up when the rising height of the floating medicine bin pipe is consistent with the height of the upper end of the pushing head of the corresponding pushing piece, the lowest part of the floating medicine bin pipe is judged to be free of the medicine, and the controller sends a prompt signal.
