Description

Technical Field

[0002] Biochemical reagents refer to biological materials or organic compounds related to life science research, as well as reagents used in clinical diagnosis and medical research. Due to the wide range and rapid development of life science, such reagents are of various types and complex in nature. Most existing biological reagents exist in the form of solutions. In production, filling biological reagents in solution form into containers containing biological reagents through filling machines is a common means of producing biological reagents.

[0003] For example, a Chinese patent with application number CN202222224449.9 discloses a biological reagent filling device, including a workbench and a reagent containing mechanism; a turntable, a filling box, a filling nozzle and a controller are arranged inside the workbench, the filling box is connected with the filling nozzle, a motor is fixedly connected to one side of the workbench, and the output end of the motor passes through the workbench and is connected to the turntable.

[0004] However, the structural design of the above filling equipment has the following problems during use:

[0005] The above filling equipment arranges multiple reagent containing mechanisms at intervals on a turntable, and the turntable rotates to pass each reagent containing mechanism through the filling nozzle in turn, and then the reagent in the filling box is filled into the reagent containing mechanism. However, since the reagent containing mechanism is installed on the turntable manually or mechanically, there is a risk of missing, and the above equipment has no detection mechanism. When the missing position on the turntable passes the filling nozzle, the reagent will drip on the turntable, causing a waste of reagent and increasing production costs.

[0006] Therefore, there is an urgent need for a filling device that can accurately fill and avoid reagent waste. Utility Model Content

[0029] To facilitate the understanding of the present disclosure, the present disclosure will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present disclosure can be understood more thoroughly and comprehensively.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present disclosure belongs. The terms used in the description of the present disclosure in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] The present disclosure provides a filling device for biological reagents, including a conveying mechanism, a filling mechanism and a detection mechanism. The conveying mechanism includes a workbench and a conveyor belt. The conveyor belt is installed on the workbench and is used to convey a test tube jig. The filling mechanism includes a first rack, a first moving component, a filling pump and a filling nozzle. The first rack and the filling pump are both arranged on one side of the workbench. The first moving component is installed on the first rack. The first moving component is connected to the filling nozzle and is used to drive the filling nozzle to move. The filling nozzle is connected to the filling pump. The detection mechanism includes a mounting bracket and a sensing component. The mounting bracket is installed on the workbench. The sensing component is connected to the mounting bracket and is used to sense and detect the test tube jig on the conveyor belt. The sensing component is electrically connected to the first moving component.

[0033] The above-mentioned filling device for biological reagents uses a conveyor belt to transport a test tube jig. Multiple test tubes are placed in the test tube jig. The first moving component drives the filling nozzle to move so that the filling nozzle corresponds to the test tubes in the test tube jig, and then the test solution in the filling pump is filled into the test tubes through the filling nozzle. Specifically, when the test tube jig is transported to the position of the sensing component, the sensing component detects the test tubes in the test tube jig. When the sensing component detects that a test tube is not filled, the sensing component releases a signal to stop the first moving component. On the contrary, when the sensing component detects that the number of test tubes is correct, the first moving component works normally to complete the filling operation. In this way, the test solution can be accurately filled into the test tubes, and the waste of reagents is avoided.

[0034] To better understand the technical solutions and beneficial effects of the present disclosure, the following further elaborates on the present disclosure in conjunction with specific embodiments:

[0035] As Figures 1 to 3 shown, a filling device 10 for biological reagents in an embodiment includes a conveying mechanism 100, a filling mechanism 200, and a detection mechanism 300. The conveying mechanism 100 includes a workbench 110 and a conveyor belt (not shown in the figure). The conveyor belt is installed on the workbench 110 and is used to transport a test tube jig. The filling mechanism 200 includes a first frame 210, a first moving component 220, a filling pump 230, and a filling nozzle 240. The first frame 210 and the filling pump 230 are both arranged on one side of the workbench 110. The first moving component 220 is installed on the first frame 210. The first moving component 220 is connected to the filling nozzle 240 and is used to drive the filling nozzle 240 to move. The filling nozzle 240 is communicated with the filling pump 230. The detection mechanism 300 includes a mounting frame 310 and a sensing component 320. The mounting frame 310 is installed on the workbench 110. The sensing component 320 is connected to the mounting frame 310 and is used to sense and detect the test tube jig on the conveyor belt. The sensing component 320 is electrically connected to the first moving component 220.

[0036] In this embodiment, the sensing component 320 is installed in front of the filling mechanism 200. The conveyor belt transports the test tube jig, and multiple test tubes are arranged at intervals in the jig. When the jig is transported below the sensing component 320, the sensing component 320 detects the test tubes in the jig. If the number of test tubes is inaccurate, the sensing component 320 releases a signal to alarm, causing the device to stop working. When the number of test tubes is correct, the jig is transported to the filling mechanism 200, and the first moving component 220 drives the filling nozzle 240 to move so that the filling nozzle 240 corresponds to the test tube mouths. The filling pump 230 works to fill the test solution into the test tubes through the filling nozzle 240, completing the filling operation. Further, the sensing component 320 is a sensor.

[0037] The above-mentioned filling device 10 for biological reagents uses a conveyor belt to transport the test tube fixtures. Multiple test tubes are installed in the test tube fixtures. The first moving component 220 drives the filling nozzle 240 to move so that the filling nozzle 240 corresponds to the test tubes in the test tube fixtures, and then the test solution in the filling pump 230 is filled into the test tubes through the filling nozzle 240. Specifically, when the test tube fixture is transported to the position of the sensor 320, the sensor 320 detects the test tubes in the test tube fixture. When the sensor 320 detects that a test tube is not filled, the sensor 320 releases a signal to stop the first moving component 220. On the contrary, when the sensor 320 detects that the number of test tubes is correct, the first moving component 220 works normally to complete the filling work. In this way, the test solution can be accurately filled into the test tubes, and the waste of reagents is avoided.

[0038] As Figure 2 shown, in one embodiment, the mounting frame 310 is provided with a clamping interface 311. A part of the sensor 320 is located in the clamping interface 311 and is clamped with the mounting frame 310, so that the sensor 320 is fixed to the mounting frame 310, and the sensing port of the sensor 320 faces the conveyor belt.

[0039] As Figure 2 shown, in one embodiment, the number of the sensors 320 is multiple, and the number of the clamping interfaces 311 is multiple. The clamping interfaces 311 are arranged in one-to-one correspondence with the sensors 320. It can be understood that multiple test tubes are installed in the test tube fixture, and the number of the sensors 320 is arranged corresponding to the number of test tube placement stations in the fixture, so as to detect whether the number of test tubes in the fixture is correct through the sensors 320.

[0040] As Figure 2 shown, in one embodiment, the multiple sensors 320 are arranged at intervals along the vertical direction of the mounting frame 310. In this embodiment, the multiple sensors 320 are arranged corresponding to the test tube placement stations in the fixture, so that the sensors 320 can quickly detect whether the number of test tubes in the fixture is accurate.

[0041] As Figure 2 shown, in one embodiment, the mounting frame 310 is provided with a first screw hole 312, and the workbench 110 is provided with a second screw hole (not shown in the figure). The first screw hole 312 and the second screw hole are used for screws to pass through, so that the mounting frame 310 is screwed to the workbench 110. In this embodiment, the mounting frame 310 and the workbench 110 are fixedly screwed together by screws.

[0042] As Figures 1 to 3As shown, in one embodiment, the first moving component 220 includes a first horizontal driving member 221, a first vertical driving member 222, and a clamping plate 223. The first horizontal driving member 221 is installed on the first frame 210. The power output end of the first horizontal driving member 221 is connected to the first vertical driving member 222. The power output end of the first vertical driving member 222 is connected to the clamping plate 223, and the clamping plate 223 clamps the filling nozzle 240. In this embodiment, the first horizontal driving member 221 drives the filling nozzle 240 to move in the horizontal direction, and the first vertical driving member 222 drives the filling nozzle 240 to move in the vertical direction, so that the filling nozzle 240 moves in multiple dimensions, thereby realizing the process of aligning with the test tube and filling the test solution into the test tube. Further, the first horizontal driving member 221 and the first vertical driving member 222 are motors or cylinders.

[0043] As Figure 4 shown, in one embodiment, the filling device further includes a loading tray 400 and a tube clamping mechanism 500. The loading tray 400 is arranged on one side of the workbench 110. The loading tray 400 is used for vibrating feeding. The tube clamping mechanism 500 includes a second frame 510, a second moving component 520, and a grasping member 530. The second frame 510 is installed on the workbench 110. The second moving component 520 is connected to the second frame 510. The second moving component 520 is used to drive the grasping member 530 to move, and the grasping member 530 is used to grasp the test tube on the loading tray 400 onto the conveyor belt. In this embodiment, the loading tray 400 is a vibrating loading tray 400 to vibrate-feed the test tubes to a preset position. The second moving component 520 is installed on the second frame 510. The second moving component 520 drives the grasping member 530 to move, so that the grasping member 530 grasps the test tubes in the vibrating loading tray 400 onto the fixture on the conveyor belt. Further, the grasping member 530 can be a cylinder clamping plate 223 or a suction-type nozzle.

[0044] As Figure 5 shown, in one embodiment, the second moving component 520 includes a second horizontal driving member 521 and a second vertical driving member 522. The second horizontal driving member 521 is installed on the second frame 510. The power output end of the second horizontal driving member 521 is connected to the second vertical driving member 522. The power output end of the second vertical driving member 522 is connected to the grasping member 530. In this embodiment, the second horizontal driving member 521 drives the grasping member 530 to move in the horizontal direction, and the second vertical driving member 522 drives the grasping member 530 to move in the vertical direction, so that the grasping member 530 moves in multiple dimensions, thereby realizing grasping the test tubes in the loading tray 400 onto the fixture on the conveyor belt. Further, the second horizontal driving member 521 and the second vertical driving member 522 are motors or cylinders.

[0045] As Figure 1 and Figure 4 shown, in one of the embodiments, the sensing member 320 is located between the tube clamping mechanism 500 and the filling mechanism 200. It can be understood that the tube clamping mechanism 500 first grabs the test tubes in the loading tray 400 to the fixture on the conveyor belt. The fixture is conveyed by the conveyor belt to the position of the sensing member 320. The sensing member 320 detects whether the number of test tubes in the fixture is correct. If the number of test tubes is correct, the conveyor belt conveys the fixture to the filling mechanism 200 for filling. If a test tube is missed during loading, the sensing member 320 emits a signal to stop the operation of the device.

[0046] This application also provides a biological reagent production device, including the filling device 10 for biological reagents described in any of the above embodiments.

[0047] Compared with the prior art, the present disclosure has at least the following advantages:

[0048] For the above-mentioned filling device 10 for biological reagents, the conveyor belt conveys the test tube fixture. The test tube fixture contains multiple test tubes. The first moving assembly 220 drives the filling nozzle 240 to move so that the filling nozzle 240 corresponds to the test tubes in the test tube fixture, and then the test solution in the filling pump 230 is filled into the test tubes through the filling nozzle 240. Specifically, when the test tube fixture is conveyed to the position of the sensing member 320, the sensing member 320 detects the test tubes in the test tube fixture. When the sensing member 320 detects that a test tube is missed during loading, the sensing member 320 emits a signal to stop the first moving assembly 220 from working. On the contrary, when the sensing member 320 detects that the number of test tubes is correct, the first moving assembly 220 works normally to complete the filling work. In this way, the test solution can be accurately filled into the test tubes, and waste of reagents is avoided.

[0049] The above-described embodiments merely represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
