Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pharmaceutical packaging, and in particular to an intelligent capping device for medical reagent bottles. Background Art
[0002] Existing capping equipment generally uses multiple rotating wheels to abut against the bottle cap, so that the friction between the rotating wheels and the bottle cap drives the bottle cap to rotate relative to the bottle body of the reagent bottle, thereby achieving the effect of tightening the bottle cap onto the bottle body of the reagent bottle.
[0003] However, when the bottle cap is tightened onto the body of the reagent bottle by the rotating wheel, the directions of the friction forces applied to the bottle cap by different rotating wheels may not be on the same plane. As a result, there are common problems such as instability when tightening the cap, loose tightening of the cap, or overtightening of the cap, which leads to a high defective rate of the produced reagent bottles. Utility Model Content
[0004] In order to facilitate tightening the bottle cap onto the reagent bottle and reduce the defective rate of reagent bottle production, the present application provides an intelligent capping device for medical reagent bottles.
[0005] The present application provides an intelligent capping device for medical reagent bottles using the following technical solutions:
[0006] An intelligent capping device for a medical reagent bottle, comprising:
[0007] The conveying component is arranged inside the rack and is used to transport the reagent bottles inside the rack;
[0008] The positioning component is connected to the conveying component and is used to position the reagent bottles transported by the conveying component to facilitate subsequent processing;
[0009] The cover screwing component is arranged close to the positioning component, and a cover clamping caliper is connected to the side of the cover screwing component facing the positioning component. The cover clamping caliper can move toward the positioning component, and a trigger switch is abutted on the side of the cover clamping caliper away from the positioning component. The trigger switch is used to control the rotation of the cover clamping caliper.
[0010] By adopting the above technical solution, the conveying component can transport the medical reagent bottle and the matching bottle cap to the positioning component and the capping component in the intelligent bottle cap screwing device for the medical reagent bottle. The positioning component can position the reagent bottles transported by the conveying component one by one, making it convenient for the bottle cap to be aligned with the reagent bottle. The capping device aligns the bottle caps with the reagent bottle one by one through the cap clamp. When the cap clamp drives the bottle cap to contact the reagent bottle, the trigger switch is activated due to the reaction force exerted on the cap clamp, and the cap clamp begins to rotate, thereby tightening the bottle cap and the reagent bottle. When the bottle cap is tightened, the reaction force exerted by the reagent bottle on the cap clamp changes again, thereby triggering the trigger switch, which controls the cap clamp to stop rotating. By controlling the rotation of the cap clamp by the trigger switch, the state of the bottle cap screwing is controlled, reducing the probability of the bottle cap being too tight or too loose, thereby reducing the defective rate of the reagent bottle production.
[0011] Optionally, the clamping cover caliper includes a plurality of clamping blocks, the number of the clamping blocks is at least 3, a limiting groove is provided in the middle of the clamping block, and the clamping block can move toward the center of the clamping cover caliper.
[0012] By adopting this technical solution, when the cap clamping caliper clamps a bottle cap, the clamping block moves toward the center of the caliper, thereby clamping the bottle cap in the retaining groove in the middle of the clamping block. At least three clamping blocks can simultaneously abut the bottle cap from at least three directions, thereby clamping the bottle cap and reducing the probability of the bottle cap falling out of the cap clamping caliper. The retaining groove further defines the position of the bottle cap on the cap clamping caliper, further reducing the probability of the bottle cap falling out of the cap clamping caliper.
[0013] Optionally, the positioning component includes a positioning turntable, a positioning slot is provided on the circumference of the positioning turntable, the positioning slot is used to clamp the reagent bottle, and a contact belt is provided at the bottom end of the positioning slot, the contact belt is used to contact the bottom end of the reagent bottle.
[0014] By adopting the above technical solution, when the reagent bottle contacts the positioning turntable, the reagent bottle is clamped into the positioning groove of the positioning turntable, and the positioning turntable clamps the reagent bottle through the positioning groove, thereby achieving the positioning of the reagent bottle. The abutment belt can abut the bottom end of the reagent bottle, so that the height of the reagent bottle is consistent, thereby determining the position of the reagent bottle and facilitating the tightening of the bottle cap on the reagent bottle.
[0015] Optionally, the conveying component includes an input end and an output end, the input end includes a bottle body input belt and a bottle cap input belt, the input end is arranged opposite the positioning turntable and connected to the abutment belt, and the output end is arranged along the rotation direction of the positioning turntable and is located on the side of the positioning component away from the input end.
[0016] By adopting the above technical solution, the bottle body is placed into the medical reagent bottle intelligent capping device from the bottle body input end, and the bottle cap is placed into the medical reagent bottle intelligent capping device from the bottle cap input end, which reduces the probability of confusion between the bottle body and the bottle cap, thereby facilitating the assembly of the bottle body and the bottle cap.
[0017] Optionally, an abutment ring is disposed on the outer side of the positioning turntable, the abutment ring connects the input end and the output end, and the abutment ring connects the side of the abutment belt away from the positioning turntable.
[0018] By adopting the above technical solution, the abutment ring can frictionally abut the reagent bottle between the input end and the output end, thereby reducing the probability of the reagent bottle being separated from the positioning turntable.
[0019] Optionally, a smart capping device for a medical reagent bottle further includes a detection device, which is used to detect whether the bottle cap is tightened.
[0020] By adopting the above technical solution, a detection device is arranged to detect whether the bottle cap is tightly closed on the reagent bottle, so as to determine whether the bottle cap is screwed too tightly and difficult to open, or the bottle cap is screwed too loosely and easily detached from the reagent bottle.
[0021] Optionally, the detection device includes a telescopic rod and an infrared detection probe, the telescopic rod is located above the positioning slot, and the infrared detection probe is arranged parallel to the end surface of the positioning turntable.
[0022] By adopting the above technical solution, the telescopic rod moves toward the bottle cap. When it touches the bottle cap, the telescopic rod will be compressed and contracted. By recording the contracted position of the telescopic rod, the height of the bottle cap can be obtained, and then it can be judged whether the bottle cap is tightened.
[0023] Optionally, a screening device is connected to a side of the detection device facing away from the tightening device, and the screening device is arranged close to the positioning turntable and connected to the output end.
[0024] By adopting the above technical solution, the screening device can screen out the reagent bottles that have been tightened through the positioning component and the tightening device, thereby delivering the reagent bottles that have been tightened in the positioning component to the output end, facilitating the transportation of good products and, at the same time, reducing the probability of transporting defective products.
[0025] Optionally, the screening device includes a baffle, an end of the baffle facing away from the abutment belt is connected to a driving cylinder, the driving cylinder is controlled by the detection device, and the baffle is located at the port of the output end and blocks the port of the output end.
[0026] By adopting the above technical solution, when it is detected that the reagent bottle is tightened properly, the baffle can rise under the drive of the motor so that the qualified reagent bottle can enter the output end, while the unqualified reagent bottle will be abutted by the baffle and cannot enter the output end. It will be sent into the collection frame along with the positioning component and collected as a defective product.
[0027] Optionally, an intelligent capping device for medical reagent bottles includes a collection frame and an infrared detector, wherein the collection frame is arranged at the end of the abutment ring along the rotation direction of the positioning turntable, and the infrared detector is located on both sides of the collection frame, and the infrared rays emitted by the infrared detector are located on the path where defective products fall.
[0028] By adopting this technical solution, reagent bottles that have not yet entered the output port fall under the action of gravity into a collection frame. Infrared detectors can detect the reagent bottles that enter the collection frame. By recording the number of reagent bottles that enter the collection frame, the number of defective products generated is determined, and the defective rate of the intelligent medical reagent bottle capping device is calculated. When the defective rate is too high, the staff can stop the device, thereby reducing the losses that may be caused by the capping device malfunctioning.
[0029] In summary, this application includes at least one of the following beneficial technical effects:
[0030] 1. When the intelligent capping device for medical reagent bottles is in operation, the conveying component transports the bottle cap and the body of the reagent bottle to the positioning component. The positioning component positions the reagent bottle and bottle cap. Then, the capping clamp in the capping component clamps the bottle cap and moves it toward the body of the reagent bottle. When the bottle cap touches the body of the reagent bottle, the trigger switch is activated, which drives the capping clamp to rotate, and the bottle cap begins to tighten against the bottle body. When the bottle cap is tightened, the trigger switch is triggered again, causing the capping clamp to stop rotating. This reduces the probability of the bottle cap being too tight or too loose, and reduces the defective rate of reagent bottles produced.
[0031] 2. The positioning slots on the positioning turntable can clamp the bodies of the reagent bottles in the transport assembly, thereby achieving individual positioning of the reagent bottles. At the same time, the bottom ends of the reagent bottles are abutted by the abutment belt to maintain the same height of the reagent bottles, allowing the cap clamp to better control the depth of the bottle cap screwed into the reagent bottle;
[0032] 3. After the bottle cap is tightened onto the reagent bottle, the detection device can detect whether the bottle cap is properly screwed onto the reagent bottle. When it is detected that it is qualified, the screening device can screen the qualified reagent bottles to the output end of the transport device, thereby outputting the qualified reagent bottles, while the unqualified reagent bottles will rotate with the positioning turntable and eventually be collected by the collection frame.

[0037] The following is combined with Figure 1-3 This application is described in further detail.
[0038] The present application embodiment discloses an intelligent capping device for medical reagent bottles. Figure 1 and Figure 2 The intelligent capping device for medical reagent bottles includes a conveying component 1, a positioning component 2 and a capping component 3.
[0039] The conveying component 1 is arranged inside the frame and is used to transport reagent bottles inside the frame. The positioning component 2 is connected to the conveying component 1 and is used to position the reagent bottles transported by the conveying component 1. The capping component 3 is arranged above the positioning component 2. The side of the capping component 3 facing the positioning component 2 is connected to a clamping caliper 31, which can move in a direction perpendicular to the plane where the positioning component 2 is located. The side of the clamping caliper 31 facing away from the positioning component 2 is provided with a trigger switch 32. The clamping caliper 31 can abut against the trigger switch 32, and the trigger switch 32 is used to control the rotation of the clamping caliper 31.
[0040] After the body of the reagent bottle enters the medical reagent bottle intelligent capping device, the reagent bottle is positioned by the positioning component 2, and the bottle cap moves toward the body of the reagent bottle under the clamping of the clamping cap caliper 31, and then abuts against the body of the reagent bottle. When the bottle cap abuts against the body of the reagent bottle, the trigger switch 32 is triggered, thereby driving the clamping cap caliper 31 to rotate, and the bottle cap begins to combine with the body of the reagent bottle. When the bottle cap is tightened, the trigger switch 32 is triggered again, thereby stopping the clamping cap caliper 31 from rotating, and the bottle cap is no longer tightened. By controlling the rotation of the clamping cap caliper 31 through the trigger switch 32, the probability of the bottle cap being too loose or too tight is reduced, thereby reducing the defective rate of the reagent bottle production.
[0041] Reference Figure 1 and Figure 3 The conveying component 1 includes an input end 11 and an output end 12, which are located on opposite sides of the positioning component 2. The input end 11 includes a bottle body input belt 111 and a bottle cap input belt 112, both of which are connected to the positioning component 2. The bottle cap input belt 112 is arranged near the cap clamping caliper 31. The input end 11 is connected to the abutment belt 22 and faces the center of the positioning turntable 21. The output end 12 is arranged along the rotation direction of the positioning turntable 21 and is located on the side of the positioning component 2 away from the input end 11.
[0042] The bottle body and the bottle cap are fed separately, so that the bottle body is positioned by the positioning component 2 and the bottle cap is clamped by the cap clamping clamp 31, thereby reducing the probability of confusion caused by the bottle body and the bottle cap being fed at the same time.
[0043] Reference Figure 1 The positioning component 2 includes a positioning turntable 21, and a positioning slot 211 is provided on the circumference of the positioning turntable 21. The size of the positioning slot 211 fits the reagent bottle. The bottom end of the positioning slot 211 is provided with an abutment belt 22, which can be spaced apart from the positioning turntable 21. The abutment belt 22 is used to abut the bottom end of the reagent bottle. An abutment ring 23 is provided on the outer side of the positioning turntable 21. The abutment ring 23 is spaced apart from the outer side of the positioning turntable 21. The abutment ring 23 is located between the input end 11 and the output end 12. The abutment ring 23 is fixedly connected to the side of the abutment belt 22 away from the positioning turntable 21, and the reagent bottle is clamped by the positioning turntable 21 and the abutment ring 23.
[0044] The positioning turntable 21 rotates to position the bottle body of the input end 11 separately through the positioning slot 211, thereby determining the horizontal position of the reagent bottle, and the abutment belt 22 abuts the bottom end of the reagent bottle to determine the horizontal height of the reagent bottle. Finally, it is convenient for the cap clamp 31 to tighten the bottle cap onto the reagent bottle.
[0045] Reference Figure 1 and Figure 2 The cap clamp 31 includes a plurality of clamping blocks 311, with at least three, preferably three or four, of which a limiting slot 312 is defined in the middle. The limiting slot 312 is preferably square and conforms to the shape of the bottle cap. An abutment block is slidably connected to the side of the clamping block 311 facing away from the positioning turntable 21. The abutment block has a chute disposed toward the center of the abutment block, into which the clamping block 311 slidably connects.
[0046] When the cap clamping caliper 31 is working, the clamping block 311 moves toward the center of the cap clamping caliper 31 to clamp the bottle cap entering through the input end 11. The bottle cap clamped by the clamping block 311 falls into the limiting groove 312, and is thereby limited by the groove wall of the limiting groove 312, thereby determining the position of the bottle cap, which is convenient for subsequent judgment of whether the bottle cap and the bottle body of the reagent bottle are tightened.
[0047] Reference Figure 1 and Figure 3 The intelligent capping device for medical reagent bottles also includes a detection device 4 for detecting whether the bottle cap is tightened. The detection device 4 includes a telescopic rod 41 and an infrared detection probe 42. The telescopic rod 41 is located above the positioning slot 211. The infrared detection probe 42 is arranged behind the telescopic rod 41 along the rotation direction of the positioning turntable 21 and parallel to the end surface of the positioning turntable 21.
[0048] When checking whether the bottle cap of the reagent bottle is tightened, the telescopic rod 41 moves toward the reagent bottle, records the position when the telescopic rod 41 touches the bottle cap, and then compares the position when the telescopic rod 41 touches the bottle cap when the bottle cap is normally tightened, so as to judge whether the bottle cap is tightened. The infrared detection probe 42 is arranged parallel to the end face of the positioning turntable 21. When the bottle cap is loose, the bottle cap will block the light path of the infrared detection probe 42, and the infrared detection probe 42 can judge whether the bottle cap is loose.
[0049] Reference Figure 1 and Figure 3 The side of the detection device 4 facing away from the tightening device is connected to a screening device 7. The screening device 7 is arranged near the positioning turntable 21 and connected to the output end 12. The screening device 7 includes a baffle 71, which is located between the output end 12 and the positioning turntable 21. The end of the baffle 71 facing away from the output end 12 is connected to a drive cylinder 72. The drive cylinder 72 is controlled by the detection device 4. Part of the transmission belt at the output end 12 is located on the abutment belt 22.
[0050] The screening device 7 can immediately screen the reagent bottles with the caps screwed on after the detection device 4 has tested them. By driving the cylinder 72 to drive the baffle 71, the conveyor belt at the output end 12 can output qualified reagent bottles. When the detection device 4 detects unqualified reagent bottles, they will be blocked by the baffle 71 of the screening device 7, thereby reducing the probability of defective products being mixed with qualified products.
[0051] Reference Figure 1 and Figure 3A smart capping device for medical reagent bottles also includes a collection frame 5 and an infrared detector 6. The collection frame 5 is located behind the baffle 71 along the rotation direction of the positioning turntable 21. The collection frame 5 is located below the positioning turntable 21 and at the end of the abutment ring 23 and the abutment belt 22. Unqualified reagent bottles will fall directly into the collection frame 5 due to the lack of abutment between the abutment ring 23 and the abutment plate. The infrared detector 6 is fixedly connected to the inner wall of the collection frame 5. Defective products that fall from the positioning turntable 21 will pass through the infrared rays emitted by the infrared detector 6.
[0052] The collection frame 5 collects defective products detected by the detection device 4. When these products fall into the collection frame 5, the infrared detector 6 detects them and records the defective product data. This recorded data is then compared with the total number of reagent bottles input to determine the defective rate of the intelligent capping device for medical reagent bottles. If the defective rate is too high, workers can promptly stop the device for repairs.
[0053] The implementation principle of the intelligent capping device for medical reagent bottles in the embodiment of the present application is as follows: during the movement of the cap clamp 31 to clamp the bottle cap to the reagent bottle, when the bottle cap abuts the reagent bottle, the trigger switch 32 will be triggered, and the cap clamp 31 will rotate, thereby starting to screw the bottle cap onto the reagent bottle. After the bottle cap is tightened, the force applied to the trigger switch 32 changes again, and the trigger switch 32 is triggered again, thereby causing the cap clamp 31 to stop rotating. Ultimately, the control of the bottle cap screwing state is achieved, reducing the probability of the bottle cap being too loose or too tight, making it easier to tighten the bottle cap onto the reagent bottle, and reducing the defective rate of reagent bottle production.
[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
