[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] In order to solve the problem that the turntable of the existing medication management equipment rotates with the medicine box to complete the operation of placing and taking medicine, but the medicine box will be misplaced when following the turntable during operation; Figure 1-3 , the utility model provides the following solutions:

[0016] A device for controlling the multi-angle rotation and positioning of a turntable by multiple limit switches includes a turntable 1 and a turntable limit plate 2. The turntable limit plate 2 is mounted on the inner side of the turntable 1. A plurality of limit switch trigger assemblies 101 are provided on the inner surface of the turntable 1, wherein a reference switch trigger assembly 102 is provided between any two switch trigger assemblies 101. According to the required rotation angle, a plurality of equidistant switch trigger assemblies 101 are installed on the turntable 1, and a reference switch trigger assembly 102 is additionally installed between any two switches. This position serves as the reference position after triggering the reference switch. An arc-shaped circuit board 3 is located above the switch trigger assembly 101. A positioning switch 301 and a trigger switch 302 are provided on the surface of the circuit board body 3. There is only one positioning switch 301, and the number of trigger switches 302 used can be increased according to actual production conditions.

[0017] Example 1: N trigger switches 302 are mounted on an arc-shaped circuit board 3 concentric with a turntable 1, where N is a natural number greater than or equal to 1. When N is equal to 1, the positioning switch 301 is defined as a reference switch. The position of the trigger device when the positioning switch 301 is next triggered after being triggered by the reference switch trigger assembly 102 is defined as the reference position. Thereafter, each time the trigger device is triggered, it rotates a certain angle. The actual rotation angle is determined by multiplying the angle each time by the number of triggers.

[0018] Example 2: When N is greater than or equal to 2, after determining the reference position, each trigger device can trigger the switch N times, combining M*N angles of the trigger switch 302, where M is the number of medicine boxes. A spacer is added to each medicine box, that is, the same medicine box can store two types of medicines, and the types of medicines that can be stored can be doubled. Without changing the entire machine structure, the types of medicines can be doubled, thereby reducing production costs.

[0019] Specifically, the outer surface of the turntable limit plate 2 is provided with a main drive gear 201, and the main drive gear 201 is rotatably connected to the turntable limit plate 2. The inner side of the turntable 1 is provided with an integrally formed inner ring gear 103, and the inner ring gear 103 is engaged with the main drive gear 201. The bottom of the turntable limit plate 2 is provided with a shaft disk 202, and the turntable 1 is rotatably connected to the turntable limit plate 2 through the shaft disk 202. The main drive gear 201 is connected to the motor. When the main drive gear 201 rotates, it can drive the turntable 1 and the medicine box placed inside the turntable 1 to rotate.

[0020] Working principle: the main drive gear 201 is connected to the motor. When the main drive gear 201 rotates, it can drive the turntable 1 and the medicine box placed inside the turntable 1 to rotate. A plurality of equidistant switch trigger components 101 are installed on the turntable 1, and a reference switch trigger component 102 is installed between any two switches. This position is used as the reference position after triggering the reference switch. N switches are installed on an arc-shaped circuit board concentric with the turntable 1. N is a natural number greater than or equal to 1. When N is equal to 1, the switch is defined as the reference switch. The position of the trigger device when the switch is triggered by the reference switch trigger component 102 and the next time it is triggered is defined as the reference position. After that, each trigger device will rotate a certain angle. The actual angle to be rotated can be determined by multiplying the angle each time by the number of triggers. When N is greater than or equal to two, after determining the reference position, each trigger device can trigger N switches, combining M*N angles of the trigger switch 302.

[0021] This new invention adds a limit switch to the limit switch assembly. Each additional switch doubles the original rotation angle, effectively doubling the number of dispensable pills. This solution is simple to implement and inexpensive, without changing the mold structure or adding a limit switch trigger assembly. This reduces manufacturing, material, and installation costs, while improving operational stability and reliability.
