Detailed Implementation

[0041] The technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0042] like Figure 1As shown, a test tube capping mechanism includes a cap conveying unit 1 for conveying caps 2; a test tube conveying unit 3 for conveying test tubes; a buffer unit 4 for buffering the caps conveyed on the cap conveying unit one by one; and a gripping unit 5 for gripping the caps 2 on the buffer unit 4 to perform a capping operation on the test tubes on the test tube conveying unit 3.

[0043] The buffer unit 4 of this utility model can buffer the caps 2 on the cap conveying unit 1 one by one, so that the target cap 2 that is about to be capped can be independent of the cap conveying unit 1. This avoids the mutual interference between the gripping unit 5 and other caps 2 on the cap conveying unit 1 when the gripping unit 5 grips the cap 2, which would cause the gripping of the cap 2 to be blocked, thereby improving the efficiency and speed of gripping the cap 2.

[0044] like Figure 2-9 As shown, the pipe cap conveying unit 1 includes a hopper assembly for storing and outputting pipe caps 2; and a first chute 6, one end of which is connected to the hopper assembly and the other end of which is connected to the buffer unit 4, for conveying the pipe caps 2 output from the hopper assembly to the buffer unit 4.

[0045] The hopper assembly of this utility model can store a large number of pipe caps 2 at one time, which can reduce the number of times operators need to store pipe caps 2. Through the setting of the first chute 6 connecting the hopper assembly and the buffer unit 4 respectively, the pipe caps 2 in the hopper assembly can be transported to the buffer unit 4 one by one in an orderly manner. Since the first chute 6 can transport and store multiple pipe caps 2 at one time, when multiple pipe caps 2 are buffered to the buffer unit 4 one by one, the first chute 6 can arrange the pipe caps 2 stored in the hopper assembly in advance, so as to facilitate the pipe caps 2 to be transported to the buffer unit 4 one by one.

[0046] The hopper assembly includes a first hopper 7, a second hopper 8, and a third hopper 9 connected in sequence. The first hopper 7 is used by operators to store pipe caps 2 in an unordered manner. A picking mechanism 10 is provided inside the first hopper 7 to pick up the pipe caps 2 in the first hopper 7 one by one and transfer them to the second hopper 8. The second hopper 8 is used to buffer the pipe caps 2 input from the first hopper 7. A partition 11 is provided between the second hopper 8 and the third hopper 9. An input port 12 is provided on the partition 11 to allow the pipe caps 2 in the second hopper 8 to slide down to the third hopper 9. The third hopper 9 is provided with a second chute 13 that can move up and down and can dock with or be offset from the first chute 6 to transport the pipe caps 2 entering the third hopper 9 to the first chute 6.

[0047] By setting up multiple hoppers, this utility model not only allows operators to easily feed the pipe caps 2 directly into the hoppers for disordered storage, but also enables the disordered pipe caps 2 to be transported to the first chute 6 in an orderly manner when they are transferred between multiple hoppers, thus facilitating the transport of the pipe caps 2 one by one to the buffer unit 4.

[0048] It is understood that the picking mechanism 10 in the first hopper 7 is an existing device that can pick up and output the caps 2 one by one. In this embodiment, it specifically includes a conveyor belt 14 and a conveyor belt drive mechanism that drives the conveyor belt 14 to rotate (existing technology can be used, and it will not be described in detail). Multiple cap driving blocks 15 are evenly arranged on the surface of the conveyor belt 14, and a cap 2 transport space is formed between each two adjacent cap driving blocks 15.

[0049] The bottom of the picking mechanism 10 extends into the first hopper 7 and one side is close to the edge of the first hopper 7, so that the pipe cap drive block 15 can receive the pipe cap 2 and prevent it from sliding down from both sides of the pipe cap drive block 15 into the first hopper 7; the top of the picking mechanism 10 is connected to the second hopper 8 through the third slide 16, and the pipe cap 2 in the first hopper 7 slides down from the third slide 16 into the second hopper 8.

[0050] Furthermore, the second hopper 8 is equipped with a stirring block 17 that can move up and down to agitate the caps 2 inside the second hopper 8. When there are too many caps 2 inside the second hopper 8 and they become stuck together, preventing the caps 2 from sliding down to the third hopper 9, the up and down movement of the stirring block 17 can agitate the caps 2 inside the second hopper 8, preventing the stuck material and facilitating the better sliding of the caps 2 into the third hopper 9.

[0051] like Figure 4-7 A drop opening 18 is provided at the connection between the third hopper 9 and the first chute 6 to facilitate the pipe cap 2 to slide from the third hopper 9 into the first chute 6. A drop adjustment block 19 is provided on the side of the drop opening 18 facing the first chute 6. The bottom edge 20 of the drop adjustment block 19 is parallel to the first chute 6 and is higher than the upper edge of the pipe cap 2 when it is in the first chute 6. The top of the bottom edge 20 extends upward to form the inclined side 21 of the drop adjustment block 19, and the inclined side 21 and the extension line of the bottom edge 20 form a first angle α. The inclined side 21 is provided to allow the pipe cap 2, regardless of its position, to fall into the second chute 13 without being properly placed. During the lifting process, ensure that the inclined side 21 is touched, and then adjust the posture during the slide so that it can smoothly slide into the first chute 6; the top of the inclined side 21 extends upward to form the side 22 of the material dropping adjustment block, and the extension lines of the inclined side 21 and the side 22 form the second corner β; the second corner β extends into the inner side of the third hopper 9, which allows the cap 2 that has not fallen into the second chute 13 to fall back into the third hopper 9 smoothly along the inclined surface, waiting for the next lifting and material handling of the second chute 13, and avoiding the cap 2 that has not fallen into the second chute 13 from getting stuck in the angle formed between the second chute 13 and the third hopper 9.

[0052] Furthermore, both the first corner α and the second corner β are acute angles.

[0053] Furthermore, a baffle 23 parallel to the first slide groove 6 is provided above the first slide groove 6, and the bottom surface of the baffle 23 is higher than the upper edge of the pipe cap 2 when it is in the first slide groove 6. The baffle 23 ensures that the pipe caps 2 can be arranged neatly in the first slide groove 6, preventing them from falling apart. Figure 7 The phenomenon shown is that the stacking of the pipe caps 2 causes poor sliding or the pipe caps 2 falling out of the groove.

[0054] Furthermore, such as Figure 8-9 As shown, a vertical drive mechanism 24 is provided at the bottom of the second hopper 8 and / or the third hopper 9 for driving the stirring block 17 and the second chute 13 to move up and down. For ease of explanation, in this embodiment, the vertical drive mechanism 24 is located at the bottom of the second hopper 8.

[0055] The vertical drive mechanism 24 includes a motor 25 and a transmission wheel 26 fixedly mounted on the partition 11; the output shaft of the motor 25 and the transmission wheel 26 are connected by a conveyor belt 27; a rotating wheel 28 is provided on the transmission wheel 26; a transmission rod 29 is rotatably mounted on the rotating wheel 28; a first slide rail 30 and a second slide rail 31 are respectively provided on both sides of the partition 11 along the direction of the conveyor belt 27; a first fixed plate 32 and a second fixed plate 33 are slidably mounted on the first slide rail 30 and the second slide rail 31 respectively; an agitator block 17 is fixedly mounted on the first fixed plate 32; one end of the first fixed plate 32 is rotatably connected to the transmission rod 29; a second chute 13 is fixedly mounted on the second fixed plate 33, and the second fixed plate 33 is fixed to the conveyor belt 27 by a clamping plate.

[0056] This invention, through the arrangement of the transmission rod 29 rotatably mounted on the rotating wheel 28 and the conveyor belt 27, not only enables the simultaneous up-and-down movement of the stirring block 17 and the second chute 13, but also simplifies the device structure, reduces the number of drive mechanisms, and lowers the cost of the device.

[0057] In this embodiment, in order to improve the efficiency of the pipe cap 2 sliding from the second hopper 8 to the third hopper 9, the bottom of the inlet 12 on the partition 11 is inclined at the same angle as the second chute 13; and the rear part of the bottom of the inlet 12 is recessed downward to form a vertical groove 34; another stirring block 17 adapted to the groove 34 is provided in the groove 34, and the stirring block 17 is also fixedly installed on the first fixing plate 32. The setting of the stirring block 17 can prevent the pipe cap 2 from sliding down and staying at the bottom of the inlet 12.

[0058] Furthermore, the inner side of the third hopper 9 is provided with inclined blocks 35 along both sides of the second chute 13; both inclined blocks 35 abut against the second chute 13; the top of the inclined block 35 near the inlet 12 is flush with the bottom of the inlet 12; when the vertical drive mechanism 24 carries the second chute 13 downward to the lowest position, the top of the second chute 13 is flush with the lower side of the inclined blocks 35, so that the cap 2 can slide from the inclined blocks 35 into the second chute 13; when the vertical drive mechanism 24 carries the second chute 13 upward to the highest position and docks with the first chute 6, the space formed between the inclined blocks 35 and the second chute 13 can be used to buffer the cap 2, so that the cap 2 can be received when the second chute 13 moves downward next time.

[0059] like Figure 10 As shown, the cache unit 4 includes a cache driving mechanism 36, a fixing block 37, and a cache block 38; the fixing block 37 is horizontally installed on one side of the bottom opening of the first slide 6, and the cache block 38 is tightly disposed on one side of the fixing block 37; the cache block 38 is provided with a cache groove 39 facing the bottom opening of the first slide 6, and the cache groove 39 is provided with an opening facing the first slide 6 for receiving the tube cap 2 that slides down from the first slide 6; the cache driving mechanism 36 is used to drive the cache block 38 to move back and forth between the fixing block 37 and the bottom opening of the first slide 6; when the cache driving mechanism 36 drives ..., the cache block 38 moves back and forth between the fixing block 37 and the bottom opening of the first slide 6. The driving mechanism 36 carries the buffer block 38 from one side of the fixed block 37 toward the bottom of the first slide 6. When the buffer groove 39 is opposite to the bottom opening of the first slide 6, the buffer groove 39 can receive the tube cap 2 on the first slide 6. When the buffer driving mechanism 36 carries the buffer block 38 from one side of the bottom of the first slide 6 toward the fixed block 37, when the buffer groove 39 is misaligned with the bottom opening of the first slide 6, the gripping unit 5 grips the tube cap 2 to seal the test tube. The other part of the buffer block 38 can block the bottom opening of the first slide 6 to prevent the tube cap 2 from continuing to slide down.

[0060] This utility model, through the cooperation of the fixing block 37 and the buffer block 38, can not only buffer the tube caps 2 of the first slide 6 one by one, but also carry the tube caps 2 to one side of the first slide 6, and perform the gripping unit 5 gripping at the position on one side of the first slide 6, so as to avoid interference from other tube caps 2 on the first slide 6 when gripping in the first slide 6.

[0061] like Figure 11-12As shown, the gripping unit 5 includes a gripping drive mechanism 40 and a gripper assembly 41. The gripping drive mechanism 40 drives the gripper assembly 41 to grip the cap 2 in the buffer slot 39 and carry the cap 2 to the test tube delivery unit 3 to perform a capping operation on the test tubes on the test tube delivery unit 3. The gripper assembly 41 includes a first gripper finger 42 and a second gripper finger 43. The bottom of the first gripper finger 42 is provided with a protrusion 44. When the gripping drive mechanism 40 carries the gripper assembly 41 to grip the cap 2, it drives the first gripper finger 42 and the second gripper finger 43 to open, and the protrusion 44 can extend into the brim on the cap 2, thereby facilitating the first gripper finger 42 and the second gripper finger 43 to better grip the cap 2. When the gripping drive mechanism 40 carries the cap 2 to perform a capping operation on the test tube, since the protrusion 44 abuts against the brim, it can prevent the cap 2 from falling off the first gripper finger 42 and the second gripper finger 43. In addition, in order to allow the first gripper finger 42 and the second gripper finger 43 to disengage from the cap 2 as quickly as possible after the capping operation, this utility model only provides a protrusion 44 on the first gripper finger 42.

[0062] Furthermore, such as Figure 13 As shown, the test tube delivery unit 3 includes a delivery drive mechanism 45 and a test tube holding mechanism 46; the test tube holding mechanism 46 includes a holding channel 47 for receiving test tubes; the delivery drive mechanism 45 is used to drive the test tubes on the holding channel 47 to the path where the gripping unit 5 is located, so as to facilitate the capping operation of the gripping unit 5.

[0063] It is understood that the cache driver mechanism 36, the grab driver mechanism 40, and the transport driver mechanism 45 involved in this embodiment are all conventional existing technologies, and therefore will not be described in detail.

[0064] In addition, this utility model also discloses a sample analysis system, including the test tube sealing mechanism described above.

[0065] The above are merely embodiments of this utility model and are not intended to limit this utility model.
