[0038] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0039] Unless otherwise defined, the technical terms or scientific terms used in the present invention shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs.

Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0040] The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0041] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a sample rack conveying mechanism with an emergency function, comprising: a horizontally arranged rack body 1, and a loading mechanism 3, a horizontal pushing mechanism 5, a code scanning mechanism 6, an unloading mechanism 7 and an emergency mechanism 8 assembled on the rack body 1;

[0042] The frame 1 includes an upper panel 11 and a lower base 12 relatively fixed to the upper panel 11, and the upper panel 11 is provided with a plurality of slide grooves 111;

[0043] The loading mechanism 3 is arranged at the right end of the horizontal pushing mechanism 5 and realizes the longitudinal loading of the sample rack 9 through the slide slot 111;

[0044] The horizontal push mechanism 5 realizes the horizontal movement of the sample rack 9 from right to left;

[0045] The code scanning mechanism 6 is located at the rear side of the horizontal pushing mechanism 5 to realize the code scanning of the sample rack 9 during the horizontal movement;

[0046] The unloading mechanism 7 is arranged at the left end of the horizontal pushing mechanism 5 and realizes the longitudinal discharging of the sample rack 9 through the slide slot 111;

[0047] The emergency mechanism 8 is spaced apart from the loading mechanism 3 and is located on the left side of the loading mechanism 3 to enable the addition of emergency sample tubes.

[0048] It also includes load-in-place optocouplers, unload-in-place optocouplers, and sample rack full optocouplers.

[0049] The loading mechanism 3 pushes the sample rack 9 to realize longitudinal sampling. When the loading is in place, the optical coupler is triggered, the horizontal pushing mechanism 5 pushes the sample rack 9 to move horizontally from right to left, and the code scanning mechanism 6 realizes code scanning. After the sampling and other actions are completed, when the unloading is in place, the optical coupler is triggered, and the unloading mechanism 7 pushes the sample rack 9 to complete the unloading action. The unloading is continued until the sample rack is full and the optical coupler is triggered, prompting the customer to manually operate to recover the sample rack.

[0050] A single-tube emergency function is designed between the code scanning mechanism 6 and the sample loading rack 9. The emergency mechanism 8 is longitudinally designed to be a certain distance away from the laterally moving sample rack 9, which does not affect the lateral movement of the conventional sample rack, thereby realizing online addition of emergency samples.

[0051] The utility model realizes that emergency sample tubes can be added online at any time while the conventional sample rack is not affected in any way, and there is no need to interrupt the transportation of the sample rack for conventional tests, thereby ensuring that the emergency sample tubes and the conventional test sample rack are independent of each other and have no influence on each other in transportation actions, thus meeting the client's demand for online emergency functions, reducing costs and facilitating staff operations.

[0052] On this basis, if Figure 2 As shown, it also includes a blocking mechanism 4, which is arranged between the loading mechanism 3 and the horizontal pushing mechanism 5. The blocking mechanism 4 can separate the sample rack to be horizontally pushed from the sample rack behind, so as to ensure smooth horizontal pushing.

[0053] On this basis, if Figure 5 and Figure 6 As shown, the blocking mechanism 4 includes a first driving mechanism 41 and a driving cam 42 driven by the first driving mechanism 41 to perform eccentric rotation;

[0054] It also includes a cam follower 43, a stop baffle 44 and a first base 45. The middle part of the stop baffle 44 is rotatably installed on the first base 45. Long grooves 46 are opened on both sides of the bottom end of the stop baffle 44, and stop hooks 47 are installed on both sides of the upper end. One end of the cam follower 43 is fixed on the driving cam 42, and the other end extends into the long groove 46, so that the stop baffle 44 can rotate around the first base 45.

[0055] The driving cam 42 follows the first driving mechanism 41 to make an eccentric rotation, one end of the cam follower 43 is fixed on the driving cam 42 to make an eccentric movement together, and the other end passes through the long groove 46 of the stop baffle 44, driving the stop baffle 44 to rotate around the first base 45, and finally realizing the stop hook 47 on the stop baffle 44 to push the sample rack 9 to move. When the loading mechanism 3 pushes the sample rack, the first driving mechanism 41 drives the stop baffle 44 through the above series of transmissions, so that the stop hook 47 is located below the slide groove 111 of the upper panel 11, ensuring that the sample rack 9 passes smoothly. When the horizontal pushing mechanism 5 starts to push the sample rack 9, in order to ensure that the sample rack that is about to be pushed away horizontally will not drive the sample rack behind to move due to friction, the stop hook 47 needs to push the sample rack 9 behind a short distance backwards to separate it from the sample rack that is about to be pushed horizontally, so as to ensure the stability of the horizontal pushing.

[0056] On this basis, if Figure 3 As shown, the loading mechanism 3 includes a second driving mechanism 31, a second base 32 relatively fixed to the second driving mechanism 31, and a first synchronous belt 37 driven by the second driving mechanism 31;

[0057] The second base 32 is provided with a first linear guide rail 33 and a push handle fixing frame 34 sliding on the first linear guide rail 33, and push handle mechanisms 35 are respectively installed at both ends of the push handle fixing frame 34;

[0058] The first driving block 36 is also included. Two ends of the first driving block 36 are respectively fixed between the first synchronous belt 37 and the push handle fixing frame 34 to achieve synchronization between the push handle fixing frame 34 and the first synchronous belt 37 .

[0059] The second driving mechanism 31 drives the first synchronous belt 37 to move, and at the same time drives the first driving block 36 and the pusher fixing frame 34 fixed on the first driving block 36 to move. The pusher fixing frame 34 is synchronized with the first synchronous belt 37 to realize the longitudinal pushing of the sample rack.

[0060] On this basis, if Figure 4 and 5 As shown, the push handle mechanism 35 includes a push handle 352 rotatably mounted on the push handle fixing frame 34 via a pin 351 and a counterweight block 353 mounted at the bottom end of the push handle 352 .

[0061] When the sample rack 9 is placed on the upper panel 11 and the sample rack 11 is pushed manually, the sample rack 11 presses the head of the push handle 352 into the slide groove 111 of the upper panel 11, and the sample rack 9 passes through the push handle 352 smoothly and is placed in front of the push handle 352. The push handle 352 rotates around the pin 351 under the gravity of the bottom counterweight block 353 and is adaptively in a vertical equilibrium state. When the second driving mechanism 31 drives the push handle 352 to move forward, the upper part of the push handle 352 abuts against the sample rack 9, and the lower part of the push handle 352 abuts against the screw, ensuring that the push handle 352 is stationary, and the sample rack 9 is successfully pushed forward.

[0062] On this basis, if Figure 6 As shown, the transverse pushing mechanism 5 includes a third driving mechanism 51 and a second synchronous belt 52 driven by the third driving mechanism 51, and also includes a second driving block 53 and a second linear guide rail 54. The upper end of the second driving block 53 is fixed on the second synchronous belt 52, and the lower end is located on the second linear guide rail 54 and slides on the second linear guide rail 54 as the second synchronous belt 52 drives.

[0063] The horizontal pushing mechanism 5 also includes a horizontal pushing plate 57 and a horizontal vertical plate 58, which are vertically fixed. The horizontal vertical plate 58 is fixed on the second driving block 53. A first boss 55 is arranged on the horizontal pushing plate 57, and a second boss 56 is arranged on the sample rack 9. When the horizontal pushing mechanism 5 is working, the first boss 55 is clamped on the second boss 56.

[0064] The sample rack 9 is clamped between the transverse push plates 57. The transverse push plates and the sample rack are respectively designed with boss features. When the transverse push mechanism 5 is working, the first boss 55 is clamped on the second boss 56. The push plate boss just presses the sample rack boss to realize the up and down positioning of the sample rack.

[0065] On this basis, if Fig. 9 As shown, a groove 91 is provided on one side of the bottom end of the sample rack 9, a push plate clamping tongue 571 is provided on one end of the horizontal push plate 57, and a spring clamping tongue 59 is provided on the other end of the horizontal push plate 57. When the horizontal push mechanism 5 is working, the push plate clamping tongue 571 is located in the groove 91, and the spring clamping tongue 59 is against the other side of the bottom end of the sample rack 9.

[0066] The sample rack 9 is positioned in the left and right directions by the push plate clamping tongue 59 and the spring clamping tongue 59. When the horizontal pushing mechanism 5 is working, the push plate clamping tongue 57 is located in the groove 91, and the spring clamping tongue 59 is against the other side of the bottom end of the sample rack 9. The spring clamping tongue is a floating mechanism, and the spring clamping tongue is pushed by the spring to clamp the sample rack.

[0067] On this basis, if Figure 2 As shown, the unloading mechanism 7 has the same structure as the loading mechanism 3 and moves in opposite directions.

[0068] On this basis, if Fig.10 As shown, the emergency mechanism 8 includes a third base 81, on which a third linear guide 83 and a third driving block 84 sliding on the third linear guide 83 are arranged, on which a test tube rack 85 is installed, a magnetic buckle bracket 86 is installed on one side of the third base 81, on which a magnetic buckle 87 is installed, on which a magnetic buckle bracket 86 is installed, a magnetic suction piece 88 matching the magnetic buckle 87 is installed on the third driving block 84, and a sensor bracket and a sensor 89 installed on the sensor bracket are also installed on the third driving block 84. The customer manually pushes the test tube rack 9, and the magnetic suction piece 88 on the third driving block 84 is attracted to the magnetic buckle 87. At this time, the sample tube is transported in place, and the sample tube sensor 89 can identify the type of the sample tube. The position of the magnetic buckle is designed to ensure that the emergency sample tube is always located in front of the conventional sample rack in the longitudinal direction, and does not affect the lateral movement of the conventional sample rack.

[0069] On this basis, the driving parts of the first driving mechanism 41, the second driving mechanism 31 and the third driving mechanism 51 all adopt synchronous motors.

[0070] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific implementations. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
