Description

Technical Field

[0001] The present invention relates to the field of automation, and in particular to a reagent strip bagging mechanism. Background Art

[0002] With the continuous development of science and technology, the innovation of medical devices has been further enhanced. In today's medical devices, pre-made reagent strips are often used to test samples. Reagent strip testing has the advantages of high detection efficiency, convenient operation, and good flexibility. To ensure the accuracy of reagent strip testing, it is necessary to ensure that the reagent strip production and packaging processes are not contaminated. Reagent strips are generally placed in packaging bags or test kits. If operated manually, the efficiency is low, and it is difficult to avoid the problem of reagent strip contamination due to improper operation.

[0003] Existing automated equipment can complete the packaging of test strips, such as the invention patent with application number 201821183974.8, entitled "A Material Bagging Mechanism." The material is pushed into the packaging bag by a push rod. However, the test strip may have some residual glue during the production process, so when the push rod is removed from the packaging bag, the test strip may be taken out together, resulting in the test strip not being placed in the packaging bag, that is, there is a problem of poor test strip bagging. The packaging bag is then sealed, and the sealed packaging bag cannot be opened without damaging the packaging bag. The packaging bag without the test strip can only be thrown away, which increases the packaging cost. If labor or detection equipment is added to detect whether the packaging bag has been placed in the test strip, the equipment cost and labor cost will increase. Summary of the Invention

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Reference Attachment Figures 1 to 9 A reagent strip bagging mechanism includes a machine base 100, on which a pushing device 1, a supporting block 2 and a cover plate 3 are provided. A reagent strip channel 4 is formed between the supporting block 2 and the cover plate 3. The pushing device 1 is arranged on the side of the reagent strip channel 4 and is used to move the reagent strip in the reagent strip channel 4.

[0030] The pushing device 1 includes a pushing drive assembly 11, which is connected to a dose strip push rod 12 and a desiccant push rod 13. The dose strip push rod 12 and the desiccant push rod 13 are parallel to each other, and the dose strip push rod 12 can extend into the dose strip channel 4. The desiccant push rod 13 is outside the dose strip channel. The pushing drive assembly 11 drives the dose strip push rod 12 and the desiccant push rod 13 to move synchronously. Specifically, the opened packaging bag or packaging box is placed at one end of the dose strip channel 4, and the dose strip push rod 12 at the other end of the dose strip channel 4 pushes the reagent strip from the dose strip channel 4 into the packaging bag or packaging box. The machine base 100 is also provided with a discharge assembly, which is used to drive the dose strip channel 4 to move, that is, to drive the support block 2 and the cover plate 3 to move.

[0031] During the process of bagging the dosage strips, the dosage strip pushing rod 12 may not extend out of the dosage strip channel 4. The dosage strip channel 4 is moved by the unloading assembly so that one end of the dosage strip pushing rod is exposed outside the dosage strip channel, and the dosage strips fall due to gravity.

[0032] In some embodiments, the base 100 is provided with a desiccant placement area 90 for placing desiccant, and the desiccant placement area 90 is located on the side of the desiccant push rod 13. The base 100 is also provided with a desiccant guide block 91, and the desiccant guide block 91 is provided with a limiting groove 911. The limiting groove 911 is located on the side of the desiccant push rod 13, and the desiccant push rod 13 can extend into the limiting groove 911. The desiccant guide block 91 is located on the side of the desiccant strip channel 4, and the limiting groove 911 serves as a guide to ensure that the desiccant can accurately enter the packaging bag. The limiting groove 911, the desiccant strip push rod 12, and the desiccant push rod 13 correspond to the opening position of the packaging bag.

[0033] Specifically, when the dosage stick pusher 12 pushes the dosage stick into the packaging bag, the desiccant pusher 13 simultaneously pushes the desiccant from the limiting groove 911 of the desiccant placement area 90 into the packaging bag, thereby improving the efficiency of bagging. In some embodiments, the end of the desiccant pusher 13 facing the packaging bag is longer than the end of the dosage stick pusher 12, that is, the distance between the desiccant pusher 13 and the packaging bag opening is less than the distance between the dosage stick pusher 12 and the packaging bag opening.

[0034] Specific reference Figures 1-2 The push drive assembly 11 is a conventional drive assembly that can drive the horizontal movement of the reagent strip push rod 12 and the desiccant push rod 13. The reagent strip channel 4 acts as a limiter for the reagent strip push rod 12, ensuring smooth movement of the reagent strip push rod 12 and moving the reagent strip in the reagent strip channel into the opened packaging bag or box.

[0035] Specific reference Figures 2 to 5 The unloading assembly includes an unloading cylinder 51 and a fixed block 52 mounted on the machine base 100. A guide groove 53 is provided on the desiccant push rod 13. The unloading cylinder 51 is connected to a limiting boss 54, which is disposed within the guide groove 53. The limiting boss 54 is connected to the support block 2. A tension spring 55 is provided between the support block 2 and the fixed block 52. The fixed block 52 is provided with a slide rail 56, and the support block 2 is mounted on the slide rail 5. Connecting posts 57 are provided on both the support block 2 and the fixed block 52, and a tension spring 55 is disposed between the connecting posts 57. The support block 2 can move along the slide rail 56. The tension spring 55, the slide rail 56, and the guide groove 53 are arranged in parallel. The connecting post 57 on the support block 2 is mounted on the end near the aluminum foil bag.

[0036] In some embodiments, a return sensor 57 is provided on the side of the limiting boss 54 to sense whether the unloading cylinder 51 drives the limiting boss 54 to retract after the reagent strip is bagged.

[0037] Before the pushing device 1 works, the guide groove 53 pulls the limiting boss 54, and the tension spring 55 is in a stretched state. When the dose strip pushing rod 12 and the desiccant pushing rod 13 are pushed toward the packaging bag, the tension spring 55 is reset, and the limiting boss 54 moves in the same direction as the desiccant pushing rod 12, driving the support block 2 to move toward the packaging bag, extending the dose strip channel 4 into the packaging bag. In this embodiment, the reagent channel 4 extends into the packaging bag by 15-25 mm, ensuring that the pushing device 1 can load the reagent strip into the packaging bag. The desiccant pushing rod 13 pushes the desiccant directly into the packaging bag, and the reagent strip pushing rod 12 pushes the front end of the reagent strip into the packaging bag. The tail end of the reagent strip is still in the reagent strip channel 4. At this time, the unloading cylinder 51 drives the limiting boss 54 to move, thereby driving the reagent strip channel 4 to leave the packaging bag, that is, the support block 2, the cover plate 3 and the gate block 6 leave the packaging bag, and the front end 12 of the reagent strip pushing rod is exposed outside the reagent strip channel 4. The reagent strip falls completely into the packaging bag due to gravity, completing the reagent strip unloading action and realizing the reagent strip bagging, which can prevent the reagent strip from sticking to the reagent channel 4. Finally, the pushing drive assembly 11 drives the reagent strip pushing rod 12 and the desiccant pushing block 13 to retreat.

[0038] In some embodiments, specific reference is made to the attached Figures 3-5 And attached Figures 7-9 , a gate block 6 and an opening and closing gate assembly 7 are also provided on the machine base 100, the cover plate 3 is arranged on the support block 2, a feed slot is formed on the same side of the support block 2 and the cover plate 3, the gate block 6 is arranged on the feed slot, and the gate block 6 and the support block 2 are provided with a clamping claw avoidance groove 20, and a dosage strip channel 4 is formed between the support block 2, the cover plate 3 and the gate block 6; the opening and closing gate assembly 7 is used to drive the gate block 6 to move to realize the opening or closing of the feed slot.

[0039] Specifically, the feed slot can be exposed or blocked, the reagent strip is placed into the strip passage through the feed slot, the opening and closing gate assembly 7 closes the feed slot, and then the clamping jaws holding the reagent strip are removed from the clamping jaw avoidance slot 20. The clamping jaws are first inserted into the strip passage 4, then the reagent strip is released to fall, and finally the clamping jaws can be removed from the clamping jaw avoidance slot 20. At the same time, because the feed slot is closed and the reagent strip cannot be removed, the reagent strip will not be placed into the strip passage due to glue that may remain on the reagent strip, thereby automating the loading of the reagent strip and increasing efficiency.

[0040] The gate block 6 includes a pressing portion 61, a closing portion 62 arranged on the pressing portion 61, and a mounting portion 63 arranged on the closing portion 62. The opening and closing gate assembly 7 can contact the pressing portion 61. The closing portion 62 is arranged on the feed slot. The mounting portion 63 can be detachably mounted on the support block 2. An elastic member 64 is provided between the mounting portion 63 and the support block 2. A clamping claw avoidance groove 20 is provided on the closing portion 62.

[0041] The reagent strip passage 4 plays a certain role in limiting the reagent strip, ensuring that the pushing device 1 accurately pushes the reagent strip into the opened packaging bag, and the cover plate 3 can prevent the reagent strip from flying out from the top during the movement. The specific principle is as follows: the opening and closing gate assembly 7 cooperates with the gate block 6 to control the opening of the feed slot, and the manipulator or other existing driving mechanism drives the clamping claw to clamp the reagent strip and move it from the feed slot into the reagent strip passage 4. Then the gate block 6 closes the feed slot to prevent the reagent strip from leaving the feed slot. The clamping claw then releases the reagent strip and leaves the clamping claw avoidance groove 20 to prevent the clamping claw from taking the reagent strip away, ensuring that the reagent strip can be placed in the reagent strip passage 4. The clamping claw avoidance groove 20 on the gate block 6 corresponds to the clamping claw avoidance groove 20 on the support block 2.

[0042] The gate opening and closing assembly 7 includes upper and lower cylinders 71 installed on the machine base 100 , a connecting plate 72 connected to the upper and lower cylinders 71 , and a buckle 73 provided on the connecting plate 72 . The buckle 73 is provided above the buckling portion 61 .

[0043] The opening and closing gate assembly 7 cooperates with the gate block 6 to open or close the feed slot. The reagent strip enters the strip channel 4 through the feed slot. After the feed slot is closed, the clamp avoidance groove 20 allows the clamp to pass through, ensuring that the reagent strip can be placed in the strip channel and avoiding the problem of poor bagging. Specifically, the upper and lower cylinders 71 drive the buckle 73 to move downward, the buckle 73 contacts the upper surface of the closing portion 62, and then the buckle 73 continues to move downward, the elastic member 64 is stretched, and the gate block 6 swings to expose the feed slot. After the reagent strip is placed, the buckle 73 moves upward, the elastic member 64 returns to its original position, and the gate block 6 blocks the feed slot.

[0044] The elastic member 64 is a spring. The support block 2 is provided with a mounting slot 21, within which the mounting portion of the gate block 6 is disposed. The closing portion 62 is perpendicular to the pressing portion 61. The mounting portion 63 is provided with a gate block connecting hole 66. The support block 2 is provided with a support block connecting hole 22. Connecting pins 67 are provided within the gate connecting hole 66 and the support block connecting hole 22, securing the gate block 6 and the support block 2 together.

[0045] A discharge assembly 8 is provided on the side of the support block 2. The discharge assembly 8 includes upper and lower discharge cylinders 81, left and right discharge cylinders 82 connected to the output ends of the upper and lower discharge cylinders 81, and a discharge block 83 connected to the left and right discharge cylinders 82. The discharge block 83 is provided with a discharge rod 84 and a dose bar arrival sensor 85. The dose bar arrival sensor 85 is set on the side of the discharge rod 84. The cover plate 3 is provided with a discharge groove 86. The discharge groove 86 corresponds to the position of the clamping jaw avoidance groove 20.

[0046] The previous station tests the test strips using a conventional testing mechanism. If a test strip is found defective, the discharge assembly 8 ejects it from the strip channel 4. The specific mechanism is as follows: After the strip arrival sensor 85 detects the defective strip, the upper and lower cylinders 81 drive the discharge block 83 to move up and down, while the left and right cylinders 82 drive the discharge block 83 to move horizontally. The gate assembly 7 then pivots the gate block 6 to expose the feed slot. The discharge rod 84 on the discharge block 83 then inserts into the discharge slot 86, ejecting the defective strip from the strip channel. The connecting plate 72 is a sloped structure that facilitates the discharge of defective strips.

[0047] In some embodiments, a bag opening device and a bag expanding device 40 are provided on the side of the dose strip passage 4. The bag opening device is used to open the bag, and the bag expanding device 40 is used to expand the opened bag. The pushing device 1 pushes the reagent strip in the dose strip passage 4 into the bag. The bag opening device is an existing mechanism that opens the bag. The bag expanding device 40 is provided at one end of the dose strip pushing rod 12 and the desiccant pushing rod 13.

[0048] Specific reference Figure 6 The packaging bag expanding device 40 includes an expanding base 401 arranged on the machine base, the expanding base 401 is provided with a cylinder 402, a driving rod 403 connected to the cylinder 402, and an expanding rod 1 404 and an expanding rod 2 405 arranged on the driving rod 403, and an expanding groove 406 is provided on the side of the expanding base 401, and the expanding rod 1 404 and the expanding rod 2 405 extend out of the expanding groove 406.

[0049] After the bag opening device opens the bag, the bag expansion device 40 on the side of the bag opening device expands the bag to fully expand it, ensuring that the test strip can be loaded into the bag. Specifically, the air cylinder 402 activates the drive rod 403 to move horizontally back and forth, thereby driving the expansion rod 1 404 and the expansion rod 2 405 to move further expand the opened bag. The distance between the expansion rod 1 404 and the expansion rod 2 405 can be adjusted according to the size of the bag.

[0050] The present invention provides a reagent strip bagging mechanism, wherein a reagent strip pushing rod pushes one end of the reagent strip into the packaging bag, while the other end of the reagent strip is still in the reagent strip channel; the unloading cylinder drives the limiting boss to move, and the reagent strip pushing rod is exposed outside the reagent strip channel, and the reagent strip completely falls into the packaging bag due to gravity, which can avoid the undesirable problem of the reagent strip sticking to the reagent strip channel during the bagging process, and is conducive to reducing costs; at the same time, the pushing drive component can push the reagent strip into the packaging bag, thereby realizing automatic bagging with high efficiency; the overall structure is compact, and has good practicality and versatility.
