[0042] In the description of the present invention, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meaning of the above words in the present invention in combination with the specific content of the technical solution.

[0043] The core of the present invention is to provide a steering transfer device for a sample rack and a full-automatic sample processing system, which can be applicable to the transfer of sample racks with multiple different docking directions and realize the smooth docking of the sample racks.

[0044] In order to enable those skilled in the art to better understand the technical solutions provided by the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0045] Please combine Figures 2 - 4 with Figure 1 The present invention provides a steering transfer device for a sample rack, which is used to transfer the sample rack containing the sample container from the first position to the second position, and includes a sample rack transfer mechanism 1 and a sample rack steering mechanism 2.

[0046] Among them, the sample rack steering mechanism 2 is used to drive the sample rack transfer mechanism 1 to rotate in the circumferential direction, so that the clamping position of the sample rack transfer mechanism 1 rotates from facing the first position to facing the second position. In particular, the steering of the sample rack steering mechanism 2 can rotate within a certain range and can be bidirectional to realize the commutation function of the sample rack.

[0047] The sample rack transfer mechanism 1 is used to grab the sample rack from the first position and put it down at the second position. The first position and the second position are the track interfaces at different positions.

[0048] With the above settings, the sample rack transfer mechanism 1 completes the grasping of the sample rack, the sample rack turning mechanism 2 completes the turning, and then the sample rack transfer mechanism 1 completes the placement of the sample rack, thus realizing the function of turning and picking up the sample rack. Since the sample rack turning mechanism 2 can drive the sample rack transfer mechanism 1 to rotate within a certain range in the circumferential direction, it can be compatible with the track interfaces of different detection devices to be applicable to the transfer of sample racks with multiple different docking directions and achieve the smooth docking of the sample racks.

[0049] In a specific embodiment, as Figure 2 shown, the sample rack transfer mechanism 1 includes a first power device 109, an adapter plate 107, and a fixture 106. The adapter plate 107 is connected to the fixture 106. Specifically, the fixture 106 has a hook body and can be fixedly connected to the hanging hole of the sample rack. Of course, the fixture 106 can also be other clamping devices or hooks, and any fixture 106 that can achieve grasping and placement is within the protection scope of this case. The first power device 109 is used to drive the fixture 106 to connect to the sample rack.

[0050] When the fixture 106 is two relatively arranged jaws, the first power device 109 is a driving device for driving the fixture 106 to open and close.

[0051] Particularly, when the fixture 106 is a hook, the first power device 109 is used to drive the adapter plate 107 to move up and down and telescopically, and can quickly connect and release the sample rack. The upward movement of the hook can hook up the sample rack, and the downward movement can put down the sample rack. To prevent collision with other components during the turning process, the telescopic movement can be used to achieve the purpose of storage and space saving. It should be noted that during grasping, the first power device 109 drives the fixture 106 to sequentially perform an extending movement away from the turning transfer device direction, an upward movement, and a contracting movement in the direction close to the turning transfer device; during transportation, the sample rack turning mechanism 2 drives the sample rack transfer mechanism 1 to rotate a certain angle in the circumferential direction; during placement, the first power device 109 drives the fixture 106 to sequentially perform an extending movement away from the turning transfer device direction, a downward movement, and contract the fixture 106 after placing the sample rack.

[0052] Furthermore, the sample rack transfer mechanism 1 further includes a cam bearing 105 and a guide plate 108. The guide plate 108 is provided with a track groove, and the two ends of the track groove are respectively a grasping position and a placement position. The cam bearing 105 passes through the track groove of the guide plate 108, and the two ends are respectively connected to the first power device 109 and the adapter plate 107. Moving along the track groove can enable the fixture 106 to move up and down and telescopically.

[0053] In a specific embodiment, the first power device 109 includes two driving devices respectively for driving the up-and-down movement and the left-and-right movement, so as to achieve the purpose of the up-and-down and telescopic movement of the fixture. The driving device can be a linear motor, a telescopic hydraulic cylinder or a cylinder, etc.

[0054] In another specific embodiment, the first power device 109 is a rotary power device that can drive the rotation of a rotating shaft, such as a rotary motor, a rotary hydraulic cylinder or a cylinder, etc. The first power device 109 includes a rotary motor and a U-shaped block 110. A strip-shaped groove is provided on the U-shaped block 110, and the rotary motor is connected to the U-shaped block 110. The cam bearing 105 passes through the strip-shaped groove of the U-shaped block 110 and the track groove of the guide plate 108 and is in sliding fit. Under the combined action of the slotted opening on the U-shaped block 110 during the rotary motion of the rotary motor and the track groove on the guide plate 108, the cam bearing 105 generates up-and-down and telescopic movements.

[0055] To improve the stability during the movement of the adapter plate 107, the sample rack transfer mechanism 1 further includes a guard plate 101 and a slide rail 104. The slide rail 104 includes a vertical slide rail and a horizontal slide rail that are in relative sliding fit. The guard plate 101 is fixed with one of the vertical slide rail and the horizontal slide rail, and the adapter plate 107 is connected to the other of the vertical slide rail and the horizontal slide rail.

[0056] Meanwhile, to detect whether the grasping and placing of the sample rack are in place, the sample rack transfer mechanism 1 further includes a first sensor 102, a second sensor 103 and a third sensor 112. The first sensor 102 is used to sense whether there is a sample rack on the fixture 106 and has an anti-fooling alarm function. The second sensor 103 and the third sensor 112 are respectively used to judge the grasping position and the placing position of the fixture 106.

[0057] The steering transfer device provided in this case further includes an alarm device for alarming when the first sensor 102 senses that there is no sample rack on the fixture 106.

[0058] As Figure 3 shown, the sample rack steering mechanism 2 includes a rotating shaft 201, a bracket and a second power device 205. The transmission shaft of the second power device 205 is connected to one end of the rotating shaft 201 to drive the rotation of the rotating shaft 201. The other end of the rotating shaft 201 is connected to the sample rack transfer mechanism 1. The bracket connects the second power device 205 and the main support frame of the fully automatic sample processing system. The bracket is arranged on the fully automatic sample processing system for supporting the entire sample rack steering transfer device.

[0059] In the above embodiments, the sample rack steering mechanism 2 further includes a sensor assembly and an induction sheet 208. The induction sheet 208 is disposed on the rotating shaft 201. The sensor assembly is used to detect whether the rotation angle of the induction sheet 208 is in place. By controlling the angle of rotation of the second power device 205 through a program, the rotating shaft 201 can be rotated at different angles.

[0060] Specifically, the sensor assembly includes a fourth sensor 203 and a fifth sensor 212. The fourth sensor 203 is a pre-rotation in-place sensor, and the fifth sensor 212 is a post-rotation in-place sensor.

[0061] In addition, the method for controlling the rotation in place of the sample rack is not limited to pulse control, sensor control, and mechanical limit control.

[0062] The bracket includes two support plates 204, a bearing mounting plate 202, and a second power device fixing plate 206. The two support plates 204 are disposed opposite to each other. The bearing mounting plate 202 and the second power device fixing plate 206 are both disposed between the two support plates 204 and are arranged one above the other. The two support plates 204 are connected to the fully automatic sample processing system, and the second power device fixing plate 206 is connected to the second power device 205. The bracket is in a "ji" shape. Among them, the two support plates 204 are two sides, the bearing mounting plate 202 is disposed at the top, and the second power device fixing plate 206 is disposed in the middle. A through hole for passing through the transmission shaft is provided on the second power device fixing plate 206.

[0063] Further, a bearing cover 210 with a bearing is provided on the bearing mounting plate 202. The rotating shaft 201 passes through the bearing cover 210 and the bearing mounting plate 202 and is in transmission cooperation with the bearing.

[0064] A coupling 207 is provided between the rotating shaft 201, the bracket, and the transmission shaft of the second power device 205. The coupling 207 is located between the second power device fixing plate 206 and the bearing mounting plate 202.

[0065] The other end of the rotating shaft 201 is connected to the sample rack transfer mechanism 1 through a positioning pin 211. The positioning pin 211 can determine the installation position of the rotating shaft 201 and the support plate 111, and the positioning pin 211 is used to ensure the installation accuracy of the rotating shaft 201 and the support plate 111.

[0066] To prevent components from colliding and being damaged, the sample rack steering mechanism 2 further includes a limit pin 209 provided on the bracket. The limit pin 209 has a protection function. The limit pin 20-nine is used to ensure the safety and reliability of the structure during rotation and prevent the sample rack or parts from being damaged during impact.

[0067] During use, the initial position of the entire mechanism is as Figure 4In the shown state, when the sample rack on the line body is conveyed to position a, the second power device 205 in the sample rack turning mechanism 2 drives the sample rack conveying mechanism 1 to rotate. It rotates until the sensing piece 208 triggers the fourth inductor 203 and then rotates a specified number of pulses and stops (the number of pulses can be adjusted according to the actual installation position), reaching the position corresponding to a. The first power device 109 in the sample rack conveying mechanism 1 rotates to drive the fixture 106 to extend and hook the sample rack. The first power device 109 continues to rotate to drive the fixture 106 to rise and retract until the second inductor 103 is triggered and stops. The first inductor 102 determines whether there is material on the fixture 106. If there is no material, the system alarms. In the case of having material, the sample rack turning mechanism 2 drives the sample rack to rotate until the fifth inductor 212 is triggered and then rotates a specified number of pulses and stops (the number of pulses can be adjusted according to the actual installation position) and stops. At this time, the sample rack is conveyed to position b. The first power device 109 in the sample rack conveying mechanism 1 rotates in the reverse direction, driving the fixture 106 to complete the extension, descent, and retraction (U-shaped trajectory). The third inductor 112 is triggered to complete the sample rack rotation and turning action. The second power device 205 in the sample rack turning mechanism 2 drives the sample rack conveying mechanism 1 to rotate to Figure 4 the initial position.

[0068] For the above sample rack positions a and b, the specific rotation angle and position can be adjusted by adjusting the number of pulses. The sensing piece 208 triggers the fourth inductor 203 or the fifth inductor 212, and then the second power device 205 rotates a specified number of pulses and stops. The sample rack conveying mechanism 1 is driven by the first power device 109 to rotate the cam bearing 105 through the U-shaped block 110. The cam bearing 105 drives the adapter plate 107, and then the guiding is completed by the guiding plate 108 and the slide rail 104, so that the fixture 106 moves up and down or expands and contracts according to the shape in the groove of the guiding plate 108. The sample rack conveying mechanism 1 can use only the first power device 109 to enable the fixture 106 to drive the sample rack to complete the expansion and contraction and up and down movements, having the advantages of high efficiency, simple structure, and small occupied space.

[0069] In addition, the present application also discloses a full-automatic sample processing system, including the turning and conveying device of the sample rack disclosed in the above embodiment. Therefore, the full-automatic sample processing system with the turning and conveying device of the sample rack also has all the above technical effects, which will not be elaborated one by one here.

[0070] It should be noted that the full-automatic sample processing system is a small assembly line of multiple analytical instruments in parallel or an overall assembly line of instruments such as laboratory biochemical, immune, and urine analyzers. The turning and conveying device of the sample rack is only one of the functional modules on the full-automatic sample processing system.

[0071] The sample rack steering transfer device and the full-automatic sample processing system provided in this case solve the problem of realizing the line body docking function by rotating the sample rack by 180°; solve the function of separating the sample rack by the line body; can realize the function of rotating and docking different sample racks at various angles; the sample rack steering mechanism is designed with an anti-collision structure to prevent component impact and damage; this device adopts a modular design, with a simple structure, low cost, and is convenient for replacement and maintenance.

[0073] Specific examples are used in this article to elaborate on the principles and implementation manners of the present invention. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
