[0050] Please refer to Figures 1 to 10In an embodiment, a calibration structure 100 of a sample feeding reversing device is provided, which comprises a base 10, a reversing assembly 20, a connecting pipe 30, a driving assembly 40 and an indicating structure 50. The reversing assembly 20 comprises a housing 21 and a rotating part 22 rotatably arranged in the housing 21, the housing 21 is arranged on the base 10, and a connecting elbow 221 is arranged in the rotating part 22. The connecting pipe 30 is connected with the rotating part 22, and an adjusting handle 31 is arranged outside the connecting pipe 30. The driving assembly 40 is arranged on the base 10 and connected with the connecting pipe 30, and is used to drive the rotating part 22 to rotate. Since the connecting pipe 30 is connected with the rotating part 22, when the driving assembly 40 drives the connecting pipe 30 to rotate, the rotating part 22 is synchronously driven to rotate, so as to drive the connecting elbow 221 in the rotating part 22 to rotate, and the output end of the connecting elbow 221 can be communicated with different output pipes 200. Specifically, the connecting pipe 30 is arranged between an input pipe 300 and the connecting elbow 221.

[0051] Since the adjusting handle 31 is arranged on the connecting pipe 30, when the driving assembly 40 fails or is powered off, etc., an operator can manually rotate the connecting pipe 30 through the adjusting handle 31, so as to manually adjust the position of the connecting elbow 221, and temporarily butt the connecting elbow 221 with the corresponding output pipe 200, so as to temporarily transport the container.

[0052] The indication structure 50 is mainly used to indicate the relative position between the rotating part 22 and the shell 21, and the indication structure 50 comprises an identification part 51 and an indication part 52. The identification part 51 is arranged on the shell 21, and the identification part 51 comprises a plurality of identification units 511 which are arranged one by one corresponding to the output pipes 200. The arrangement of the identification units 511 one by one corresponding to the output pipes 200 means that the number of the identification units 511 is the same as the number of the output pipes 200, for example, in an embodiment, when the output pipes 200 are six, the identification units 511 are also six; and the arrangement position of the identification units 511 corresponds to the arrangement position of the output pipes 200, for example, in an embodiment, the six output pipes 200 are distributed along the circumference in sequence, and the six identification units 511 are also distributed along the circumference in sequence, and one identification unit 511 is opposite to one output pipe 200. The indication part 52 is arranged on the rotating part 22 and / or the connecting pipe 30, and is used to indicate the identification units 511. Since the indication part 52 is arranged on the rotating part 22 and / or the connecting pipe 30, when the connecting pipe 30 rotates, the indication part 52 also rotates, so that the indication part 52 indicates different identification units 511, and the position of the connecting elbow pipe 221 in the shell 21 can be determined. Since the shell 21 and the output pipes 200 do not rotate during rotation, the centering condition of the connecting elbow pipe 221 and the corresponding output pipe 200 can be observed intuitively. For example, when the indication part 52 points to the first identification unit 511, it indicates that the connecting elbow pipe 221 is centered with the first output pipe 200.

[0053] It can be understood that when the abnormal situation occurs and the driving assembly cannot operate normally, the position adjustment of the connecting elbow pipe becomes very difficult, and it is difficult to realize the temporary reversing of the container.

[0054] The calibration structure 100 of the sample feeding reversing device is provided with the adjusting handle 31 on the connecting pipe 30, so that when the driving assembly 40 cannot normally operate, the operator can temporarily drive the connecting pipe 30 to rotate by manually operating the adjusting handle 31, thereby adjusting the position of the connecting elbow pipe 221, manually performing the reversing operation, and connecting the connecting elbow pipe 221 with the corresponding output pipeline 200, so as to temporarily transport the container in the abnormal state. In addition, the indicating structure 50 is further provided, so that the centering condition of the connecting elbow pipe 221 can be directly observed during the manual adjustment, the accuracy of the position adjustment of the connecting elbow pipe 221 can be improved, and the connecting elbow pipe 221 can be more accurately connected with the corresponding output pipeline 200.

That is, the rotating part 22 is at least partially located outside the shell 21 and extends out of the shell 21 from the side of the first end face 211, and the indicating part 52 is arranged on the part of the rotating part 22 located outside the shell 21. Through this structure, the positions of the indicating part 52 and the identification part 51 can be closer, so that the operator can more directly observe the positional relationship between the indicating part 52 and the identification unit 511.

[0056] Preferably, in an embodiment, the identification unit 511 includes an identification arrow 5111 and a mark 5112 arranged beside the identification arrow 5111, the identification arrow 5111 points to the part of the rotating part 22 extending out of the shell 21, and the marks 5112 in each identification unit 5111 are different. The identification arrow 5111 can more directly display the positional relationship between the indicating part 52 and the identification unit 511, and the mark 5112 can make the operator more directly know the output pipeline 200 corresponding to the current identification unit 511. Specifically, in an embodiment, the arrow 5111 is a triangular structure formed by being recessed from the first end face 211, and the end point of the arrow 5111 points to the part of the rotating part 22 extending out of the shell 21. The type of the mark 5112 can be selected according to requirements, for example, numbers or symbols can be used. Preferably, in an embodiment, the mark 5112 is a number mark, so that it can be more directly matched with the corresponding output pipeline 200.

[0063] Preferably, in an embodiment, the calibration structure 100 of the sample feeding reversing device further comprises a position detection structure 60, which comprises an inductive sheet 61 and a position detection sensor 62. The inductive sheet 61 is connected with the connecting pipe 30. The position detection sensor 62 is arranged in one-to-one correspondence with the output pipe 200 to detect the position of the inductive sheet 61. Wherein, the one-to-one correspondence arrangement of the position detection sensor 62 with the output pipe 200 means that the number of the position detection sensor 62 is not less than the number of the output pipe 200, for example, in an embodiment, when the output pipe 200 has six, the position detection sensor 62 also has six; and the position detection sensor 62 is arranged in correspondence with the position of the output pipe 200, at least one position detection sensor 62 is arranged corresponding to each output pipe 200, for example, in an embodiment, six output pipes 200 are distributed along the circumference in sequence, and six position detection sensors 62 are also distributed along the circumference in sequence. Since the inductive sheet 61 is connected with the connecting pipe 30, the inductive sheet 61 can rotate synchronously with the connecting pipe 30, and the position detection sensor 62 is arranged in correspondence with the output pipe 200, so that when the connecting elbow pipe 221 is rotated and connected with one output pipe 200, the inductive sheet 23 will also be rotated to the detection area of the corresponding position detection sensor 62, so that the corresponding detection signal can be output through the position detection sensor 62 to feedback the position of the connecting elbow pipe 221.

The proximity switch is a sensing device that detects the position, state, speed, and other parameters of a target by using the changing characteristics of an inductive device in an inductive load circuit. The use of the proximity switch can reduce cost, reduce the space required, and provide faster response, easy installation, and good reliability. More specifically, in an embodiment, the position detecting sensor 62 is an inductive proximity switch.

[0067] Preferably, in an embodiment, the connecting pipe 30 includes a fixed pipe 32 and a rotating pipe 33. The fixed pipe 32 is used to connect with the input pipe 300. The rotating pipe 33 is rotatably connected with the fixed pipe 32 and is connected with the driving assembly 40 and the rotating part 22, respectively. That is, in this embodiment, the connecting pipe 30 is divided into a fixed part (i.e., the fixed pipe 32) and a rotating part (i.e., the rotating pipe 33). The fixed part is used to connect with the input pipe 300, and the rotating part is used to connect with the rotating part 22. When the driving assembly 40 drives the rotating pipe 33 to rotate, the rotating pipe 33 rotates relative to the fixed pipe 32, so that the output pipe 300 is not rotated. Specifically, the adjusting handle 31 is arranged on the rotating pipe 33.

[0068] Specifically, in an embodiment, a bearing 34 is arranged between the rotating pipe 33 and the fixed pipe 32 to reduce the wear between the rotating pipe 33 and the fixed pipe 32. More preferably, in an embodiment, a sealing member is arranged on each side of the bearing 34 in the axial direction to improve the sealing effect between the rotating pipe 33 and the fixed pipe 32.

[0069] Preferably, in an embodiment, the fixed pipe 32 is provided with a connecting arm 321 at an end away from the rotating pipe 33. The connecting arm 321 is used to be inserted into a sliding groove on the input pipe 300. Through the cooperation between the connecting arm 321 and the sliding groove, the fixed pipe 32 and the input pipe 300 can be axially displaced to a certain extent to facilitate the connection between the pipes. Further, a connecting flange sleeve 35 can be arranged outside the connecting arm 321 and the sliding groove, so that the connecting position of the fixed pipe 32 and the input pipe 300 is shielded and sealed by the connecting flange sleeve 35. More preferably, a sealing member can be arranged in the connecting flange sleeve 35 to improve the sealing effect between the fixed pipe 32 and the input pipe 300.

[0070] Preferably, in an embodiment, the driving assembly 40 comprises a motor 41 with an encoder and a transmission mechanism 42 connected with the motor 41, the transmission mechanism 42 is connected with the connecting pipe 30 to drive the connecting pipe 30 to rotate by the motor 41. Wherein, the transmission mechanism 42 can adopt any power transmission structure, such as gear transmission, chain transmission, etc., as long as the power output by the motor 41 can be transmitted to the reversing assembly 20 through the transmission mechanism 42, thereby driving the connecting elbow pipe 221 to rotate, allowing the output end of the connecting elbow pipe 221 to communicate with different output pipelines 200. By setting the motor 41 with an encoder, when the driving assembly 40 drives the connecting elbow pipe 221 to rotate to the end, the pose of the motor 41 can be fed back through the encoder. And in an embodiment, the position of the sensing sheet 61 can be fed back synchronously through the position detection sensor 62, so as to determine the centering condition of the connecting elbow pipe 221 through the signals of the encoder and the rotation-to-position signal, improve the positioning accuracy of the connecting elbow pipe 221, and more stably transport the container. The encoder is superior to the proximity switch in control accuracy, accuracy recovery, anti-interference ability and resolution. Therefore, they are generally suitable for more complex and higher performance automation architecture and environment. Specifically, the encoder can be used in pairs with a grating reading head or a magnetic sensor, which can output a digital signal in real time for the controller to read, thereby determining the pose of the motor 41.

By using an absolute value encoder, the current position of the motor can be directly measured, and the anti-interference ability of the encoder and the reliability of the data can be further improved. By using a servo motor as a rotary drive source, the repeatability is high, the speed is fast, and the service life is long.

[0072] Specifically, in an embodiment, the bending radius of the connecting elbow pipe 221 is 800 mm, so as to ensure that the container passes smoothly and quickly during transmission, and to realize bidirectional transmission of the container in the calibration structure 100 of the sample feeding reversing device.
