[0001] The utility model relates to the technical field of in vitro detection equipment, in particular to a double-track corner transport device and a sample transport system. Background Art

[0002] The assembly line is an automated, intelligent and standardized production method. In the current medical testing field, the assembly line is widely used in the testing and transportation of various types of samples, greatly improving the testing and processing efficiency of samples and saving labor costs.

[0003] With the development of assembly line systems, due to the diverse conditions of various laboratory sites, higher requirements have been placed on the layout of assembly line systems. It is necessary to increase the flexibility of assembly line placement so that the assembly line is not limited to linear transmission. Therefore, most of them add corner transport devices to change the direction of assembly line transportation, making the assembly line placement more flexible and better adapting to the space constraints of the laboratory. However, current corner transport devices mostly use a single track to transport sample racks. Before the sample racks are transported to the corner transport device, they must go through a complex scheduling process. If the conditions are not met, the sample racks will wait on the transport track. For this type of corner transport device and the corresponding single-track assembly line conveying system, the track occupancy rate is high, the occupancy time is long, and the transportation scheduling is complex, which greatly limits the transportation efficiency of the entire assembly line.

[0008] Preferably, protective baffles are provided on both sides of the sample rack conveyor belt, and the protective baffles are provided with notches corresponding to the position sensor and the telescopic rod.

DETAILED DESCRIPTION

[0021] The following is a more detailed description of the embodiments of the present invention with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the invention after studying this specification. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example

[0022] The utility model provides a double-track corner transport device, which includes a base 10 , a corner platform 11 , and two corner tracks 20 arranged on the corner platform 11 .

[0023] like Figure 1 As shown, the base 10 is provided with a rotating bearing, and the rotating shaft of the corner platform 11 is rotatably connected to the rotating bearing. The base 10 is also provided with a drive device that is transmission-connected to the rotating shaft of the corner platform 11. The drive device includes a motor 121 mounted on the base 10, a synchronous wheel 122 mounted on the rotating shaft of the corner platform 11, and a synchronous belt 123 transmission-connected between the motor output shaft and the synchronous wheel 122. When the sample rack enters the corner track 20, the motor 121 drives the corner platform 11 to rotate via the synchronous belt 123, thereby changing the transport direction of the sample rack.

[0024] Furthermore, the base 10 is provided with a plurality of position sensors 13 evenly distributed around the rotation axis of the corner platform 11. A trigger member 14 is provided at the bottom of the corner platform 11. When the trigger member 14 passes by the position sensor 13, it can detect whether the corner platform has been rotated to the correct position. The position sensors 13 can be through-beam photoelectric sensors, and there are generally four of them to detect 90° rotation of the corner platform 11.

[0025] Two corner rails 20 are provided on the corner platform 11, and the two corner rails 20 are symmetrical around the rotation axis of the corner platform 11. Figure 2The corner track 20 includes a sample rack conveyor belt 21, two position sensors 22 disposed on one side of the sample rack conveyor belt 21, and two telescopic rods 23 disposed on the other side of the sample rack conveyor belt 21. The sample rack conveyor belt 21 can be a belt conveyor for transferring sample racks. Protective baffles 24 are provided on both sides of the sample rack conveyor belt 21 to prevent the sample racks from tilting or falling during transportation and rotation. The protective baffles 24 also have notches corresponding to the position sensors 22 and telescopic rods 23. The position sensor 22 can be a photoelectric sensor, and the telescopic rods 23 can be a through-axis linear stepper motor or an electric, hydraulic, or pneumatic push rod. The spacing between the two position sensors 22 is greater than the length of the sample rack. The positions of the two telescopic rods 23 correspond to the two position sensors 22. When extended, the telescopic rods 23 extend above the sample rack conveyor belt 21 to block the sample rack. Regardless of the direction from which the sample rack enters the sample rack conveyor belt 21, when the sample rack completely passes a position sensor 22, the sample rack conveyor belt 21 stops, and the two telescopic rods 23 are simultaneously extended to control the sample rack between the two telescopic rods 23, preventing the sample rack from shifting or tipping over when the corner platform rotates, thereby improving the reliability of sample rack transportation. Example

[0026] The present invention provides a dual-track sample transport system, including a connection module 30 and an in vitro detection device, wherein the in vitro detection device is provided with a sample injection module 40. The connection module 30 and the sample injection module 40 can refer to the relevant technology. In this embodiment, Figures 3-5 As shown, the connection module 30 and the injection module 40 both include a pair of parallel transport rails 31 and a track-changing device 32 arranged between the pair of transport rails 31; the transport rails 31 can adopt a belt conveyor for linearly transporting the sample rack; the track-changing device 32 can refer to relevant technologies and be used to complete the track change of the sample rack between the two transport rails 31, usually including a support plate connected between the two transport rails 31 and a pusher for pushing the sample rack to move, thereby realizing one-way track change; two pushers with opposite moving directions can also be used to realize two-way track change of the sample rack.

[0027] A corner transport device 50 is installed between two adjacent connection modules 30, between two adjacent injection modules 40, or between adjacent connection modules 30 and injection modules 40, forming a sample rack assembly line transport system that allows for the sample racks to be transported in different directions. The corner transport device 50 is the dual-track corner transport device described in Example 1, comprising two corner tracks 20, each corresponding to a pair of transport tracks 31. Space is provided between the corner transport device 50 and the connection modules 30 or injection modules 40 for rotation.

[0028] When the sample rack is transported to the transport track 31 in front of the corner transport device 50, if the front of the current track is occupied by other sample racks, it can be transferred to another transport track 31 through the track changing device 32, and then the transport direction can be changed through the corner transport device 50. After passing the corner, the track can be changed again, solving the problems of high track occupancy rate, long occupancy time and complex transport scheduling in the single transport track assembly line conveying system.

[0029] The corner transport device 50 and the plurality of connection modules 30 and / or the injection module 40 can realize a variety of corner transport forms, and can be connected to form one of L-type, U-type, Z-type and T-type. The connection modes of L-type, Z-type and T-type are respectively as follows: Figures 3-5 As shown, the arrow in the figure indicates the transportation direction of the sample rack.

[0030] The above is a description of one or more embodiments of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
