Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0040] The specific implementation of the present application will be described in detail below in combination with specific embodiments.

[0041] In an embodiment of the present application, referring to Figures 1-8 The blood collection tube cap direction recognition device comprises a base 1, a base mounting plate 101 is arranged on the base 1, a slot-shaped switch support 102, a motor mounting plate 103 and a semicircular piece 106 are vertically arranged on the base mounting plate 101, a slot-shaped switch 104 is arranged on the slot-shaped switch support 102, a motor 105 is arranged on the motor mounting plate 103, and the motor body is parallel to the base mounting plate 101, a tube-dropping opening 1061 is arranged at the lowest end of the semicircular piece 106, a code disc 210 and a rotating disc 2 are installed on the output shaft of the motor 105, the code disc 210 passes through the U-shaped slot of the slot-shaped switch 104, and two detection ports that are equally divided by 180° are arranged on the code disc 210, a rotating disc holder 203 is arranged on the rotating disc 2, a rotating disc passage 2031 for the blood collection tube 3 to pass through is arranged on the rotating disc holder 203, a pair of light-electricity 201 is arranged at the middle position of the rotating disc passage 2031, the pair of light-electricity 201 is installed on the rotating disc holder 203, a baffle 207 is arranged at the upper right side of the rotating disc passage 2031, the upper end of the baffle 207 is connected with a compression spring 204, the center position of the baffle 207 is empty for the sliding block 206 to pass through, the other end of the compression spring 204 is connected with the rotating disc holder 203, the sliding block 206 is irregularly shaped, has a rectangular slot in the center, and is fixed on the rotating disc holder 203 through a limiting column 205, one end of the sliding block 206 passes through the baffle 207, and the other end of the sliding block 206 is exposed to the rotating disc 2, a diffuse reflection photoelectricity 208 is arranged at the lower right side of the rotating disc passage 2031, a rotating disc holder cover 209 is arranged on the rotating disc holder 203 to prevent the blood collection tube from falling off when the rotating disc rotates,

[0042] In the present embodiment, the working process of the device is that the test tube is pushed into the rotating disc channel 2031 by the push tube mechanism (not shown), and the blood collection tube 3 is moved under the action of the push tube mechanism (not shown) by virtue of the characteristics that the tube body of the blood collection tube 3 is small in diameter and the cap is large in diameter. When the cap of the blood collection tube 3 is pushed forward, the cap is blocked by the baffle 207, at this time, only the signal of the light emitting diode 201 has a signal, and the signal of the diffuse reflection photoelectric cell 208 has no signal. According to the state of the two photoelectric signals, the rotating direction of the motor 105 is determined. After the rotating direction of the motor 105 is determined, the motor 105 works to drive the rotating disc 2 and the code disc 210 to rotate clockwise. In the rotating process, the sliding block 206 is retracted into the rotating disc 2 under the action of the semicircular part 106. In the process of retraction of the sliding block 206, the limiting column 205 is fixed and does not move. The limiting column 205 moves through the sliding block 206 and in the middle of the sliding block 206. Since the sliding block 206 is irregularly shaped, the sliding block 206 drives the baffle 207 to move upward in the process of backward movement of the sliding block 206, and the rotating disc channel 2031 is opened. When the rotating disc 2 rotates 90° clockwise, the motor stops working. Due to the action of gravity, the cap of the blood collection tube 3 drops downward from the tube dropping port 1061. When the signal of the light emitting diode 201 has no signal and the signal of the diffuse reflection photoelectric cell 208 changes from nothing to something and then to nothing, the rotating disc 2 is driven by the motor 105 to rotate 90° counterclockwise. Under the action of the compression spring 204, the baffle 207 and the sliding block 206 return to the initial state. When the cap of the blood collection tube 3 is pushed forward into the rotating disc channel 2031, the blood collection tube 3 can be pushed to the bottom, and the baffle 207 cannot block. The light emitting diode 201 and the diffuse reflection photoelectric cell 208 both have signals. According to the state of the two photoelectric signals, the rotating direction of the motor 105 is determined. After the rotating direction of the motor 105 is determined, the motor 105 works to drive the rotating disc 2 to rotate counterclockwise. When the rotating disc 2 rotates 90° counterclockwise, the motor stops working. Due to the action of gravity, the cap of the blood collection tube 3 drops downward from the tube dropping port 1061. After a certain time delay, when the signals of the light emitting diode 201 and the diffuse reflection photoelectric cell 208 both have no signal, the rotating disc 2 is driven by the motor 105 to rotate 90° clockwise, and the rotating disc 2 returns to the initial state. Thus, the function of direction recognition of the blood collection tube is completed.

[0043] Further, if the cap of the blood collection tube 3 is forward, when the blood collection tube 3 is pushed into the rotating disc channel 2031, the motor 105 works to drive the rotating disc 2 to rotate clockwise. In the rotating process, the sliding block 206 is retracted into the rotating disc holder 203 under the action of the semicircular part 106. In the process of retraction of the sliding block 206, the sliding block 206 moves backward. Since the sliding block 206 is irregularly shaped, the sliding block 206 drives the baffle 207 to open in the process of backward movement of the sliding block 206. In this process, all the functions are realized by linkage of mechanical components, without any inspection and control, which is simple, practical, safe and reliable.

[0044] Further, the whole structure, only two photoelectric (pair of photoelectric 201 and diffuse reflection photoelectric 208) and a motor 105 with work can complete the blood collection tube 3 direction discrimination and processing work, the whole process test signal is less, control is simple.

[0045] The blood collection tube cap direction identification device of the application is to identify the cap direction of the blood collection tube 3, and to process and output the blood collection tube 3 with the same cap direction. The structure is simple and the control is simple. The application realizes the function of outputting the blood collection tube 3 with the same cap direction. The mechanical structure is simple, and the linkage limiting method is used to realize the control. The structure is simple. Only two photoelectric signals (pair of photoelectric 201 and diffuse reflection photoelectric 208) and a motor 105 are used to realize the control, so the control is simple, convenient and practical.

[0046] It can be understood that the application is described through some embodiments, and those skilled in the art can make various changes or equivalent replacements to the features and embodiments without departing from the spirit and scope of the application. In addition, the features and embodiments can be modified to adapt to specific conditions and materials under the guidance of the application without departing from the spirit and scope of the application.
