[0017] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0018] See also Figure 1 and Figure 2 , which is a schematic diagram of the structure of an embodiment of the present application. The test tube head cap detection device of the present application mainly includes a frame 1, a flip wheel 2, a first driving mechanism, a push plate assembly 3, a first photoelectric sensor 4, a second driving mechanism, a second photoelectric sensor 5, a third photoelectric sensor 6, a first micro switch 7, a second micro switch 8, a first first connecting plate group 122 and a second first connecting plate group 123. For the specific structure, please refer to the following description.

[0019] The frame 1 is used as a support for the entire device. The frame 1 includes two side panels 1-1 and a support plate 1-2. The support plate 1-2 is disposed between the two side panels 11 and at the rear end of the frame 1.

[0020] The flip wheel 2 is disposed between the two side plates 1-1 and at the front end of the frame 1. The flip wheel 2 includes a wheel body 21 and a roller 22 disposed at one end of the wheel body 21. A horizontal groove 23 is provided in the middle of the wheel body 21, and the horizontal groove 23 is used to place and fix the test tube 9. A plurality of vertical spacing grooves 24 are provided on the wheel body 21. The flip wheel 2 is used to drive the test tube to rotate to the detection position.

[0021] The first driving mechanism is used to connect and drive the flip wheel 2 to rotate in a directional manner. Figure 2 As shown, the first driving mechanism includes a first motor 101, a first gear set 102 and a first belt 103. The first motor 101 is fixed on the frame 1, and the first motor 101 drives the first gear set 102 to rotate. The first belt 103 is sleeved on the first gear set 102 and the roller 22. The first belt 103 rotates the roller 22 under the directional drive of the first gear set 102, and then drives the flip wheel 2 to rotate in a directional manner.

[0022] The end of the push plate assembly 3 is fixed to the front end of the support plate 1-2 and is located at the upper end of the flip wheel 2. The push plate assembly 3 can rotate upward with the center point of the end. The two ends of the push plate assembly 3 are provided with contact plates 31 extending downward, and the contact plates 31 are inserted into the spacing grooves 24. As the flip wheel 2 rotates upward, if there is a test tube 9 in the groove 23, the test tube 9 touches the contact plate 31, and then the test tube 9 pushes the push plate assembly 3 to flip upward along the end.

[0023] The first photoelectric sensor 4 is fixed to the front end of the support plate 1-2 and is located at the upper end of the push plate assembly 3. The first photoelectric sensor 4 is electrically connected to the first driving mechanism. When the push plate assembly 3 is flipped to a certain angle, the first photoelectric sensor 4 is blocked, and a signal is sent to the first motor, and then the first motor stops moving.

[0024] The push plate assembly 3 and the first photoelectric sensor 4 are used to confirm whether there is a test tube 9 in the groove 23 of the flip wheel 2, so as to prepare for detection.

[0025] The second driving mechanism is fixed on the support plate 1-2. The second driving mechanism includes a second motor 111, a second gear set 112, a belt adjustment wheel 113 and a second belt 114. The second motor 111 drives the second gear set 112 to move forward or reversely. The belt adjustment wheel 113 is arranged above the support plate 1-2 and is used to adjust the direction of the second belt 114 on the support plate 1-2. The second belt 114 is sleeved on the second gear set 112 and each belt adjustment wheel 113. Driven by the second motor 111, the second belt 114 drives the first first connecting plate set 122 and the second first connecting plate set 123 to move horizontally toward or oppositely.

[0026] Combination Figure 1 and Figure 2 As shown, the first first connecting plate group 122 and the second first connecting plate group 123 are basically symmetrical structures. The head ends of the first first connecting plate group 122 and the second first connecting plate group 123 are fixed to the second belt 114 through a clamping portion 14. With the drive of the second motor 111, the first first connecting plate group 122 and the second first connecting plate group 123 move in the horizontal direction. The ends of the first first connecting plate group 122 and the second first connecting plate group 123 are located on both sides of the upper end of the flip wheel 2, and the first micro switch 7 and the second micro switch 8 that are normally open are respectively arranged in the middle of the ends of the first first connecting plate group 122 and the second first connecting plate group 123. The first micro switch and the second micro switch are located on the same horizontal line. The first first connecting plate group 122 and the second first connecting plate group 123 move in the middle under the drive of the second motor 111 and then clamp to the test tube 9, and the first micro switch 7 or the second micro switch 8 that is normally open is compressed and then triggered, thereby determining the position and direction of the test tube head cap. The specific explanation will be further described in detail in the following working principle.

[0027] The second photoelectric sensor 5 and the third photoelectric sensor 6 are arranged on a fixed plate 15, and the fixed plate 15 is fixed to the upper end of the support plate 1-2. The second photoelectric sensor 5 is arranged at the starting position of the first first connection plate group 122. When the first first connection plate group 122 moves to the second photoelectric sensor 5, the second photoelectric sensor 5 sends a signal to control the second motor 111 to stop moving. The third photoelectric sensor 6 is arranged at the limit position of the first first connection plate group 122, and the limit position is perpendicular to the corresponding side edge of the push rod assembly 3, that is, the outer side edge of the contact edge 311. When the first first connection plate group 122 moves to the third photoelectric sensor 6, the third photoelectric sensor 6 sends a signal to control the second motor 111 to stop moving.

[0028] The working principle of this application is:

[0029] 1. Determine whether the test tube is in the flip wheel 2 and drive the test tube to the detection position.

[0030] The first motor 101 drives the first gear set 102 to rotate; the first gear set 102 rotates and drives the first belt 103, so that the first belt 103 rotates in a directional manner. The first belt 103 drives the flip wheel 2 to rotate. The test tube 9 is located in the groove of the first belt 103.

[0031] If there is a test tube 9, the flip wheel 2 rotates with the test tube 9, and the test tube 9 pushes the push plate assembly 3. The end of the push plate assembly 3 in contact with the test tube 9 tilts upward, and the other end moves downward, so that the signal of the normally open first photoelectric sensor 4 is disconnected. If there is no signal from the first photoelectric sensor 4, the first motor 101 stops working. Then there is a test tube 9 in the groove 23 of the flip wheel 2, and it reaches the specified position, and the detection position.

[0032] 2. Detection

[0033] The second motor 111 drives the second gear set 112 to rotate, and then drives the second belt 114 to make the second belt 114 rotate forward or reverse.

[0034] The second belt 114 rotates, driving the first connecting plate group 12 and the second connecting plate group 13 to move horizontally. The second belt 114 is forward, and the first connecting plate group 12 and the second connecting plate group 13 move horizontally toward the middle until the two ends of the test tube 9 are clamped, and the second motor 111 stops working; the second belt 114 is reversed, and the first connecting plate group 12 and the second connecting plate group 13 move horizontally to both sides, loosening the two ends of the test tube 9 (the function of the first connecting plate group 12 and the second connecting plate group 13 is to move with the second belt (fixed on the second belt) until the two ends contact the test tube 9 and then stop moving. After one end contacts the test tube, it will continue to move (carrying the test tube) until the two ends contact the test tube and then stop. Or it stops when it reaches the limit position of the third photoelectric sensor 6. The first connecting plate group 12 and the second connecting plate group 13 move under the drive of the second belt in order to trigger one of the two micro switches at the center of its end).

[0035] When the first connecting plate group 12 reaches the position of the second photoelectric sensor 5 or the third photoelectric sensor 6 during the horizontal movement, the second photoelectric sensor 5 or the third photoelectric sensor 6 receives a signal. If the second photoelectric sensor 5 or the third photoelectric sensor 6 has a signal, the second motor 111 stops working. The first connecting plate group 12 reaches the limit position or the starting position.

[0036] The first micro switch 7 and the second micro switch 8 are located at the center of the lower end of the first connecting plate group 12 and the second connecting plate group 13. When one of them is triggered, the position of the test tube head cap is determined according to the given test tube type. Different test tube types have different triggering positions (for example, the center of the nucleic acid tube head cap is a plane, and the center of the tail is a groove; the urine tube has a groove on the head cap and a protruding circle on the tail. Most test tubes have this characteristic, with one end concave and the other end protruding). Therefore, the position of the test tube head cap can be determined according to the different triggering points of the micro switch.

[0037] See also Figure 3 As shown, it is a schematic diagram of the use of the present application. As can be seen from the schematic diagram, the test tube head cap detection device A of the present application can be applied to the automatic labeling production line, which can play a good judgment role and effectively assist the accurate labeling.

Equivalent changes and modifications made to the present invention by those skilled in the art should all fall within the scope of the claims attached to the present invention.
