In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0040] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0041] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0042] In the embodiment of the present application, the reagent strip filling device 100 includes a loading mechanism 1, a filling mechanism 2, a film sealing mechanism 3, a detection mechanism 4 and a discharge mechanism 5, which are arranged in sequence, and a circular transport platform 6. A material seat 7 is provided on the circular transport platform 6, and the material seat 7 is used to carry the reagent strip 10. Through the function of the circular transport platform 6, the material seat 7 that completes the loading of the reagent strip 10 at the loading mechanism 1 can pass through the filling mechanism 2, the film sealing mechanism 3, and the detection mechanism 4 in sequence to reach the discharge mechanism 5, and complete the filling, film sealing, detection and discharge of the reagent strip 10. After the discharge is completed at the discharge mechanism 5, the material seat 7 can return to the loading mechanism 1 to reload the reagent strip 10, so that the automation of the production process of the reagent strip 10 can be realized, the production capacity can be improved, and the labor cost can be reduced.

[0043] The present application is described below through specific embodiments.

[0044] Embodiment 1:

[0045] like Figures 1 to 26 As shown, in one embodiment of the present application, a reagent strip filling device 100 is provided, including a loading mechanism 1, a filling mechanism 2, a film sealing mechanism 3, a detection mechanism 4 and a discharge mechanism 5, and a circulating transport platform 6. A material seat 7 is provided on the circulating transport platform 6, and the material seat 7 is used to carry the reagent strip 10. The circulating transport platform 6 is used to drive the material seat 7 to move from the loading mechanism 1 to the discharge mechanism 5 through the filling mechanism 2, the film sealing mechanism 3, and the detection mechanism 4 in sequence, and / or drive the material seat 7 to move from the discharge mechanism 5 to the loading mechanism 1. The loading mechanism 1 is used to load the reagent strip 10 onto the material seat 7. The filling mechanism 2 is used to fill the reagent strip 10 on the material seat 7 with reagent. The film sealing mechanism 3 is used to perform film sealing on the filled reagent strip 10. The detection mechanism 4 is used to detect the quality of the film sealing of the reagent strip 10. The discharge mechanism 5 is used to discharge the reagent strip 10 from the material seat 7.

[0046] Through the action of the circulating transport platform 6, the material seat 7 that has completed the loading of the reagent strip 10 at the loading mechanism 1 can sequentially pass through the filling mechanism 2, the film sealing mechanism 3, and the testing mechanism 4 to reach the unloading mechanism 5, completing the filling, film sealing, testing and unloading of the reagent strip 10. After unloading at the unloading mechanism 5, the material seat 7 can return to the loading mechanism 1 to reload the reagent strip 10, so that the automation of the production process of the reagent strip 10 can be realized, the production capacity can be improved, and the labor cost can be reduced.

[0047] The circular transport platform 6 is used to transport the material holder 7 back and forth between the position of the loading mechanism 1 and the position of the unloading mechanism 5 to realize the automated production of the reagent strip 10. The route of the material holder 7 moving from the loading mechanism 1 to the unloading mechanism 5 cannot be the same as the route of the material holder 7 moving from the unloading mechanism 5 to the loading mechanism 1. If the routes of the two are the same, it will have a great impact on the production efficiency, resulting in low production capacity.

[0048] like Figures 1 to 5 As shown, in one embodiment, the circulating transport platform 6 includes a first transport line 61 and a second transport line 62, the two first transport lines 61 and the two second transport lines 62 are arranged in a rectangular shape, the two first transport lines 61 are arranged in parallel, the first transport line 61 and the second transport line 62 are adjacent to each other to form a rectangle, one of the two first transport lines 61 is used to drive the material holder 7 to move from the position of the loading mechanism 1 to the position of the unloading mechanism 5 in sequence through the filling mechanism 2, the film sealing mechanism 3, and the detection mechanism 4, the other of the two first transport lines 61 is used to drive the material holder 7 to move from the position of the unloading mechanism 5 to the position of the loading mechanism 1, and the second transport line 62 is used to move the material holder 7 from one of the two first transport lines 61 to the other of the two first transport lines 61. With such an arrangement, the circulating transport of the material holder 7 can be realized without affecting the progress of each process flow, thereby improving production efficiency.

[0049] In some embodiments, the first transport line 61 and the second transport line 62 are conveyor belts, the material holder 7 is placed on the conveyor belts, and the material holder 7 is circulated and transported by a rectangular conveyor belt mechanism composed of the first transport line 61 and the second transport line 62 .

[0050] In this embodiment, a first transport rail 611 is provided on the first transport line 61, and a second transport rail 621 is provided on the second transport line 62. Accordingly, a first transport slider 71 matched with the first transport rail 611 and a second transport slider 72 matched with the second transport rail 621 are provided on the material seat 7. The material seat 7 realizes reciprocating sliding on the circulating transport platform 6 through the slider and rail structure; and the material seat 7 is transported by the slider and rail structure, which can also ensure the posture stability of the material seat 7 during the movement and ensure the normal execution of the automated process flow. A track-changing auxiliary mechanism 63 is also provided on the circulating transport platform 6. When the material seat 7 moves from the first transport rail 611 to the second transport rail 621, or when the material seat 7 moves from the second transport rail 621 to the first transport rail 611, the track-changing auxiliary mechanism 63 pushes the material seat 7 to complete the matching with the auxiliary slider and rail structure to ensure the normal operation of the circulating transport platform 6.

[0051] The loading mechanism 1 is used to load the reagent strip 10 onto the material seat 7. For automated production, the posture error of the reagent strip 10 needs to be controlled within a relatively small range. Therefore, the reagent strip 10 should be positioned before being loaded onto the material seat 7. Since the reagent strip 10 is placed on the plane of the material seat 7, the reagent strip 10 needs to be positioned in two mutually perpendicular directions within the plane.

[0052] Specifically, Figures 6 to 11 As shown, in one embodiment, the loading mechanism 1 includes a bidirectional positioning mechanism 11 and a first manipulator 12 . The bidirectional positioning mechanism 11 is used to position the reagent strip 10 , and the first manipulator 12 is used to move the positioned reagent strip to the material seat 7 .

[0053] In this embodiment, the bidirectional positioning mechanism 11 includes a storage seat 111, a first positioning mechanism, a second positioning mechanism and a driving assembly 114. The storage seat 111 is used to place the reagent strip 10. The first positioning mechanism is arranged on the storage seat 111, and the first positioning mechanism reciprocates in the first direction, and is used to push the reagent strip 10 in the first direction to complete the positioning of the reagent strip 10 in the first direction. The second positioning mechanism is arranged on the storage seat 111, and the second positioning mechanism reciprocates in the second direction, and is used to push the reagent strip 10 in the second direction to complete the positioning of the reagent strip 10 in the second direction. The first direction is perpendicular to the second direction to ensure that the bidirectional positioning mechanism 11 can complete the positioning of the product to be positioned on the storage plane of the storage seat 111. The driving assembly 114 includes a first driving arm 1141 and a second driving arm 1142. The first driving arm 1141 is fixedly connected to the second driving arm 1142. The first driving arm 1141 is provided with a first pushing member, and the first pushing member is connected to the first positioning mechanism. The second driving arm 1142 is connected to the second positioning mechanism. The first driving arm 1141 is used to drive the first pushing block 112, and the second driving arm 1142 is used to drive the second pushing block 113. Since the first driving arm 1141 is provided with a first pushing member, the first pushing member is connected to the first positioning mechanism, the second driving arm 1142 is connected to the second positioning mechanism, the first driving arm 1141 and the second driving arm 1142 are fixedly connected, when the first driving arm 1141 and the second driving arm 1142 move in the second direction, the first driving arm 1141 drives the first positioning mechanism to move in the first direction through the first pushing member, and the second driving arm 1142 drives the second positioning mechanism to move in the first direction. When a single power source drives the second driving arm 1142 to move in the second direction, the second driving arm 1142 drives the second positioning mechanism and the first driving arm 1141 to move in the second direction, and the first pushing member on the first driving arm 1141 drives the first positioning mechanism to move in the first direction, so that the bidirectional positioning mechanism 11 in the present application can achieve positioning in two directions by one power source, and the spatial structure of the bidirectional positioning mechanism 11 is compact and the control cost is low.

[0054] The first positioning mechanism and the second positioning mechanism reciprocate in the first direction and the second direction respectively, that is, the first positioning mechanism should be slidably arranged on the storage seat 1 along the first direction, and the second positioning mechanism should be slidably arranged on the storage seat 1 along the second direction.

[0055] In this embodiment, the first positioning mechanism includes a first slide 1121 and a first push block 112. The first slide 1121 is slidably connected to the storage seat 111 along the first direction. The first push block 112 is arranged on the first slide 1121. The first push block 1121 is used to push the reagent strip 10 in the first direction to complete the positioning of the reagent strip 10 in the first direction. The second positioning mechanism includes a second slide 1131 and a second push block 113. The second slide 1131 is slidably connected to the storage seat 111 along the second direction. A plurality of second push blocks 113 are arranged on the second slide 1131. The first slide 1121 is connected to the first driving arm 1141, and the second slide 1131 is connected to the second driving arm 1142. In the automated production process, it is generally necessary to operate multiple products at the same time, that is, the bidirectional positioning mechanism 11 needs to position multiple reagent strips 10 at the same time, so multiple first push blocks 112 and second push blocks 113 need to work together. In this embodiment, the bidirectional positioning mechanism 11 simultaneously positions four reagent strips 10, that is, at least four first push blocks 112 are arranged on the first slide 1121, and at least four second push blocks 113 are arranged on the second slide 1131. The driving component 114 drives the first slide 1121 and the second slide 1131 through the first driving arm 1141 and the second driving arm 1142, thereby driving all the first push blocks 112 and all the second push blocks 113, thereby completing the positioning of the reagent strip 10.

[0056] The first driving arm 1141 is used to drive the first slide 1121, the second driving arm 1142 is used to drive the second slide 1131, and the first driving arm 1141 is fixedly connected to the second driving arm 1142. In this embodiment, a first driving member is provided on the first driving arm 1141, the first driving member is connected to the first slide 1121, the second driving arm 1142 is connected to the second slide 1131, and the first driving arm 1141 is fixedly connected to the second driving arm 1142. When the power source drives the second driving arm 1142 to move in the second direction, the second driving arm 1142 drives the second slide 1131 to move in the second direction, and the second driving arm 42 drives the first driving arm 41 to move in the second direction. The first driving arm 1141 then drives the first slide 1121 to move in the first direction through the first driving member, that is, the first driving member can convert the transmission input in the second direction into the transmission output in the first direction.

[0057] In some embodiments, the first pusher is a crank slider structure, and the first driving arm 1141 is connected to the first slide seat 1121 via the crank slider structure, so that the first driving arm 1141 can drive the first slide seat 1121 to move in the first direction when moving in the second direction.

[0058] In this embodiment, the first pusher on the first driving arm 1141 is a moving cam 411, and a roller 11211 is provided on the first slide 1121, and the roller 11211 abuts against the moving cam 411. When the first driving arm 1141 reciprocates along the second direction, the first slide 1121 can be driven to reciprocate in the first direction through the cooperation between the moving cam 411 and the roller 11211. With such a configuration, the cooperation structure of the roller 11211 and the moving cam 411 is compact, and the structural reliability is high, thereby ensuring the normal operation of the bidirectional positioning structure 100.

[0059] The first slide 1121 is slidably connected to the storage seat 111. To ensure normal sliding, the first slide 1121 is provided with one of a slider 1151 and a slide rail 1152, and the storage seat 111 is provided with the other of the slider 1151 and the slide rail 1152. The slider 1151 and the slide rail 1152 cooperate to complete the sliding connection between the first slide 1121 and the storage seat 111. In this embodiment, the slider 1151 is provided on the first slide 1121, and the slide rail 1152 is provided on the storage seat 111. Similarly, the second slide 1131 and the storage seat 111 are also connected through a slider and slide rail structure, the second slide 1131 is provided with a slider 1151, and the storage seat 111 is provided with a slide rail 1152 that cooperates with the slider 1151 on the second slide 1131. Those skilled in the art can understand that the dimensions of the first slide 1121 and the second slide 22 may be different. Therefore, the dimensions of the slider 1151 set on the first slide 1121 and the matching slide rail 1152 on the storage seat 111 may be different from the dimensions of the slider 1151 set on the second slide 1131 and the matching slide rail 1152 on the storage seat 111, and no limitation is made here.

[0060] The first slide 1121 reciprocates in the first direction so that the first push block 112 can complete the positioning of the reagent strip 10 in the first direction, and the second slide 1131 reciprocates in the second direction so that the second push block 113 can complete the positioning of the reagent strip 10 in the second direction; therefore, it is necessary to ensure the accurate movement of the first slide 1121 and the second slide 1131 in the first direction and the second direction.

[0061] Specifically, in this embodiment, a plurality of slide seat positioning mechanisms 1111 are provided on the storage seat 111, and a guide rod 11111 is provided on the slide seat positioning mechanism 1111, and the slide seat positioning mechanism 1111 includes a first slide seat positioning mechanism and a second slide seat positioning mechanism, the first slide seat positioning mechanism is connected to the first slide seat 1121 through the first guide rod, and the second slide seat positioning mechanism is connected to the second slide seat 1131 through the second guide rod, and an elastic member 11112 is provided on the guide rod 11111, and the first guide rod is axially arranged along the first direction, and the second guide rod is axially arranged along the second direction. Through the action of the guide rod 11111, the first slide seat 1121 has only the degree of freedom in the first direction, and can only reciprocate along the first direction; the second slide seat 1131 has only the degree of freedom in the second direction, and can only reciprocate along the second direction, so as to ensure that the first push block 112 and the second push block 113 can accurately complete the positioning of the reagent strip 10. At the same time, the elastic member on the guide rod 11111 can prevent the first slide 1121 and the second slide 1131 from deviating and thus causing inaccurate positioning. When the slide deviates, the elastic members 11112 at different positions have different degrees of deformation, and the elastic forces acting on the slide are also different, thereby pushing the slide to avoid the slide from deviating. To ensure the guiding function of the guide rod 11111, in this embodiment, the first slide 1121 and the second slide 1131 are provided with positioning holes, the first guide rod extends into the positioning hole on the first slide 1121, and the second guide rod 11111 extends into the positioning hole on the second slide 1131. When the first slide 1121 and the second slide 1131 slide, the guide rod 11111 also slides in the positioning hole. Correspondingly, the elastic member 11112 can be set as a spring sleeved on the guide rod 11111. At the same time, in order to avoid damage to the guide rod 11111 due to vibration and other reasons, a certain gap is set between the guide rod 11111 and the positioning hole arm as a buffer to increase the service life of the two-way positioning mechanism 11. Those skilled in the art can understand that the "first" and "second" in the first slide seat positioning mechanism, the second slide seat positioning mechanism, the first guide rod and the second guide rod are only used as a distinction of the setting direction to facilitate the understanding of the present application. In this embodiment, the first slide seat positioning mechanism and the second slide seat positioning mechanism have the same structure and are set in different directions; the first guide rod and the second guide rod also have the same structure and are set in different directions. In some embodiments, according to the requirements of production and manufacturing, the size specifications of the first slide 21 and the second slide 31 may be quite different. In order to achieve a better guiding effect, first slide seat positioning mechanisms and second slide seat positioning mechanisms of different specifications, as well as first guide rods and second guide rods of different specifications may be used, which are not limited here.

[0062] In this embodiment, the first clamping block 1112 and the second clamping block 1113 are fixedly provided on the storage seat 111, and the first clamping block 1112 is arranged opposite to the first push block 112, and the second clamping block 1113 is arranged opposite to the second push block 113. The first clamping block 1112 and the second clamping block 12 are used to assist in positioning the reagent strip 10. When the first push block 112 pushes the reagent strip 10, the side of the reagent strip 10 close to the first push block 112 in the first direction contacts the first push block 112, and when the first push block 112 pushes the reagent strip 10 to the other side in the first direction and abuts against the first clamping block 1112, the positioning of the reagent strip 10 in the first direction is completed. When the second push block 113 pushes the reagent strip 10, the side of the reagent strip 10 close to the second push block 113 in the second direction contacts the second push block 113, and when the second push block 113 pushes the reagent strip 10 to the other side in the second direction and abuts against the second clamping block 1113, the positioning of the reagent strip 10 in the second direction is completed.

[0063] Those skilled in the art will appreciate that for reagent strips 10 of different sizes, first slides 1121 or second slides 1131 of different sizes can be provided, and considering factors such as processing difficulty and scope of application, the size of the first slide 1121 or the second slide 1131 should not be too large. When it is necessary to push the reagent strip 10 at multiple locations on a longer scale, it is possible to consider using multiple first slides 1121 or second slides 1131 to be arranged in parallel. In the present embodiment, two first slides 1121 are arranged in parallel on the storage seat 111, and rollers 11211 are provided on the two first slides 1121. Correspondingly, two moving cams 411 are also provided on the first driving arm 1141, and two places of the reagent strip 10 are pushed by the first push blocks 112 on the two first slides 1121, so that more accurate positioning can be achieved. At the same time, the storage seat 111 in the present embodiment is also provided with a plurality of first clamping blocks 1112 between the two first slides 1121, which further ensures positioning accuracy.

[0064] In order to prevent the first push block 112 or the second push block 113 from excessively squeezing the reagent strip 10 and causing damage to the reagent strip 10, in this embodiment, a limiting member 1114 is provided on the storage seat 111, and the limiting member 1114 is used to limit the first driving arm 1141 and the second driving arm 1142, thereby preventing the first push block 112 or the second push block 113 from excessively squeezing the reagent strip 10 and causing damage to the reagent strip 10. In this embodiment, the limiting member 1114 is an elastic limiting member with an elastic limiting head. The elastic limiting head of the limiting member 1114 is provided at the moving end of the first driving arm 1141 and is used to limit the first driving arm 1141 and the second driving arm 1142. Limiting by the elastic limiting head can prevent the first driving arm 1141 from being subjected to excessive rigidity and causing damage to the driving assembly 114.

[0065] In this embodiment, the power source of the driving assembly 114 is the cylinder 1143 , the output shaft of the cylinder 1143 is connected to the second driving arm 1142 , and the cylinder 1143 drives the second driving arm 1142 and the first driving arm 1141 to reciprocate along the second direction to achieve the positioning of the reagent strip 10 .

[0066] When the bidirectional positioning mechanism 11 in this embodiment is working, the cylinder 1143 is started first, and the cylinder 1143 drives the first driving arm 1141 and the second driving arm 1142. The moving cam 411 on the first driving arm 1141 squeezes the roller 11211 on the first slide 1121, so that the first slide 1121 moves, and the first push block 112 on the first slide 1121 moves away from the first clamping block 1112. The second driving arm 41 drives the second slide 1131 to move, and the second push block 113 on the second slide 1131 moves away from the second clamping block 1113, and then the reagent strip 10 is loaded onto the storage seat 111 through other equipment, and then the cylinder 1143 is started to reversely drive the first driving arm 1141 and the second driving arm 1142, and the moving cam 411 on the first driving arm 1141 relaxes the roller 11211 on the first slide 1121, and the first slide 1121 is reset; the first push block 112 on the first slide 1121 pushes the reagent strip 10, and cooperates with the first clamping block 1112 to complete the positioning in the first direction. The second driving arm 1142 drives the second slide 1131 to move, and the second push block 113 on the second slide 1131 pushes the reagent strip 10, and cooperates with the second clamping block 1113 to complete the positioning in the second direction; at the same time, the guide rod 11111 and the elastic member 11112 on the slide positioning mechanism 1111 ensure the accuracy of positioning, and the limit member 1114 prevents the first push block 112 or the second push block 113 from excessively squeezing the reagent strip 10.

[0067] After the bidirectional positioning mechanism 11 completes the positioning of the reagent strip 10 , the second manipulator 12 moves the positioned reagent strip 10 onto the material seat 7 to complete the loading.

[0068] The filling mechanism 2 is used to fill the reagent strip 10 on the material seat 7 with reagent.

[0069] like Figures 12 to 17 As shown, in this embodiment, the filling mechanism 2 includes a filling component 21 and a filling component driving member 22. The filling component 21 is used to fill the reagent into the reagent strip 10 on the material seat 7, and the filling component driving member 22 is used to drive the filling component 21 to move to complete the filling work required at different positions.

[0070] In this embodiment, the filling assembly 21 includes a mounting seat 212, a positioning plug 213, a plurality of first filling needles 2111 and a plurality of second filling needles 2112. The second filling needle 2112 contains a different filling reagent from the first filling needle 2111. In this embodiment, the second filling needle 2112 is used to fill magnetic beads. When the equipment is shut down, the second filling needle 2112 needs to be removed for reflux treatment to avoid magnetic bead deposition. The first filling needle 2111 and the second filling needle 2112 are arranged in a preset direction to complete the small gap filling of the reagent strip. The first filling needle 2111 and the second filling needle 2112 are provided with a filling needle positioning groove 2131. The mounting seat 212 is provided with a filling needle mounting hole 2121 and a filling needle mounting groove 2122, the first filling needle 2111 is arranged in the filling needle mounting hole 2121, the second filling needle 2112 is arranged in the mounting groove, the mounting seat 212 is provided with a filling needle positioning hole 2132 connected with the filling needle mounting hole 2121 or the filling needle mounting groove 2122, and the filling needle positioning hole 2132 is arranged opposite to the filling needle positioning groove 2131. The positioning plug 213 is movably arranged in the filling needle positioning hole 2132, and the positioning plug 213 can reach a first position of extending into the filling needle positioning groove 2131, and reach a second position of exiting the filling needle positioning groove 2131. When the positioning plug 213 extends into the filling needle positioning groove 2131, the first filling needle 2111 or the second filling needle 2112 is fixed and cannot move; when the positioning plug 213 withdraws from the filling needle positioning groove 2131, the first filling needle 2111 or the second filling needle 2112 is not fixed and can move. Since the second filling needle 2112 that needs to be quickly disassembled is arranged in the filling needle installation groove 2122, the second filling needle 2112 is fixed by the cooperation of the positioning plug 213 and the filling needle positioning groove 2131. When the second filling needle 2112 needs to be disassembled, it is only necessary to pull out the positioning plug 213 from the filling needle positioning groove 2131, and the second filling needle 2112 can be taken out along the filling needle mounting groove 2122. The overall structure is compact, so that the filling assembly 21 in the present application is suitable for small gap filling occasions, and during the process of disassembling and assembling the second filling needle 2112, the second filling needle 2112 moves in and out along the filling needle mounting groove 2122 without large position swing, and will not cause cross contamination.

[0071] The first filling needle 2111 and the second filling needle 2112 are fixedly mounted on the mounting seat 212 through the cooperation of the positioning plug 213 and the filling needle positioning groove 2131. To facilitate the disassembly and assembly of the second filling needle 2112, the positioning plug 213 and the filling needle positioning groove 2131 should be easily matched.

[0072] In this embodiment, the filling needle positioning groove 2131 on the second filling needle 2112 is a circumferentially arranged groove. With this arrangement, the second filling needle 2112 can cooperate with the positioning plug 213 in the entire circumference to complete the fixation, and the operation is simple. To ensure the fixing effect, in this embodiment, the filling needle positioning groove 2131 is a V-shaped groove. The V-shaped filling needle positioning groove 2131 can decompose the pressure of the positioning plug 213 in multiple directions to ensure the fixing effect. Similarly, the filling needle positioning groove 2131 on the first filling needle 2111 can also be a circumferentially arranged V-shaped groove. In this embodiment, the positioning plug 213 is a ball plunger. When the positioning plug 213 extends into the filling needle positioning groove 2131, the elastic ball head of the ball plunger presses against the two walls of the V-shaped groove to provide sufficient pressure to fix the first filling needle 2111 or the second filling needle 2112. Accordingly, the filling needle positioning hole 2132 is a threaded hole, and the positioning plug 213 rotates forward or reversely in the filling needle positioning hole 2132 to reach the first position or the second position.

[0073] Since the second filling needle 2112 is arranged in the filling needle mounting groove 2122, the cooperation between the positioning plug 213 and the filling needle positioning groove 2131 needs to limit the three degrees of freedom of the second filling needle 2112 (the movement of the second filling needle 2112 in the axial direction, the movement of the second filling needle 2112 toward the opening direction of the filling needle mounting groove 2122 and the rotation of the second filling needle 2112 toward the opening direction of the filling needle mounting groove 2122). It is difficult to limit the rotation of the second filling needle 2112 toward the opening direction of the filling needle mounting groove 2122 by the pressure applied by a single positioning plug 213. If swinging occurs during operation, the filling assembly 21 will not be able to work normally.

[0074] Specifically, in this embodiment, the second filling needle 2112 is provided with a plurality of filling needle positioning grooves 2131, and correspondingly, the mounting seat 212 is provided with a plurality of filling needle positioning holes 2132 connected to the filling needle mounting grooves 2122. Through the action of the plurality of positioning plugs 213, the swing of the second filling needle 2112 can be effectively limited to ensure the normal operation of the filling assembly 21. In this embodiment, the axes of the plurality of positioning holes 31 are on the same plane, and the axis of the second filling needle 2112 is also on the plane, and the opening directions of the positioning holes 31 are also consistent. Such a configuration facilitates the processing of the positioning holes 31, and the operation of the positioning plugs 213 can be completed on the same side, saving space. In this embodiment, the second filling needle 2112 is provided with two filling needle positioning grooves 2131.

[0075] In this embodiment, the filling assembly 21 is used to fill the reagent strip 10 with reagents. The first filling needle 2111 and the second filling needle 2112 need to be arranged in a preset direction, and the gap between each filling needle is small. The setting of the filling needle installation groove 2122 cannot interfere with the filling needle installation hole 2121. In this embodiment, the groove wall of the filling needle installation groove 2122 is set at an angle to the preset direction, and the filling needle installation groove 2122 does not interfere with the filling needle installation hole 2121. At the same time, the filling needle installation groove 2122 is tilted, which can effectively save space and realize the rapid disassembly and assembly of the second filling needle 2112 in small gap occasions. During the disassembly and assembly process, the second filling needle 2112 moves in and out along the filling needle installation groove 2122, and does not interfere with the working space of the first filling needle 2111, thereby avoiding cross contamination. In order to ensure the fixing effect of the positioning plug 213, the axial direction of the positioning plug 213 should be perpendicular to the groove wall of the filling needle installation groove 2122. If the filling needle installation hole 2121 connected to the filling needle installation groove 2122 is directly processed on the mounting seat 212, the filling needle installation hole 2121 may be too deep, which increases the processing cost and is not convenient for the disassembly and assembly of the second filling needle 2112. Therefore, in this embodiment, a cutout 2123 is provided on the mounting seat 212, and at least one section of the cutout 2123 is parallel to the groove wall of the filling needle installation groove 2122, and the opening of the filling needle positioning hole 2132 connected to the filling needle installation groove 2122 is provided on the section. In this way, the depth of the filling needle installation hole 2121 is moderate, and the opening of the filling needle positioning hole 2132 is parallel to the groove wall of the filling needle installation groove 2122, which saves costs and facilitates the disassembly and assembly of the second filling needle 2112.

[0076] The film sealing mechanism 3 is used to perform film sealing on the filled reagent strip 10 .

[0077] like Figures 18 to 25 As shown, in this embodiment, the film sealing mechanism 3 includes a heat sealing mechanism 31 and a film material punching mechanism 32. The heat sealing mechanism 31 is used to heat-seal the filled reagent strip 10 using a heat sealing film 3110, and the film material punching mechanism 32 is used to punch the heat sealing film 3110 to punch the heat sealing film 3110 into a suitable size.

[0078] In this embodiment, the heat sealing mechanism 31 includes a suction nozzle 311 and a heat sealing head 312. The suction nozzle 311 is used to suck the heat sealing film 3110, and the heat sealing head 312 is used to heat-seal and press the heat sealing film 3110 onto the test strip 10. The suction nozzle 311 and the heat sealing head 312 are arranged to slide relative to each other. When the heat sealing head 312 heat-seals and presses the heat sealing film 3110, the heat sealing head 312 presses the heat sealing film 3110 off the suction nozzle 311. Since the suction nozzle 311 and the heat sealing head 312 are arranged to slide relative to each other, the heat sealing head 312 presses the heat sealing film 3110 off the suction nozzle 311 when the heat sealing head 312 heat-seals and presses the heat sealing film 3110, so that the suction nozzle 311 and the heat sealing head 312 can be integrated in one workstation, that is, the two processes of heat sealing film feeding and heat sealing of the heat sealing film can be completed in one workstation, the required number of mechanisms and parts are small, the length of the machine is reduced, the cost is low, the production time is short, and the production capacity is high; before the heat sealing head 312 heat-seals and presses the heat sealing film 3110, the suction nozzle 311 keeps sucking the heat sealing film 3110, and the heat sealing film 3110 will not be displaced due to not being fixed, and the product yield rate is high.

[0079] When the heat-sealing head 312 heat-seals and presses the heat-sealing film 3110 , the heat-sealing head 312 presses the heat-sealing film 3110 off the suction nozzle 311 , and the relative positions of the suction nozzle 311 and the heat-sealing head 312 should not interfere with each other.

[0080] In some embodiments, the suction nozzles 311 are arranged on both sides of the heat-sealing head 312, and each piece of heat-sealing film 3110 is sucked up by a pair or several pairs of suction nozzles 311 arranged on both sides of the heat-sealing head 312. When the heat-sealing head 312 heat-seals the heat-sealing film 3110 to the reagent strip 10, the heat-sealing head 312 heat-seals and presses the middle section of the heat-sealing film 3110 to the reagent strip 10, and the heat-sealing film 3110 is separated from the suction nozzles 311 under the action of the heat-sealing head 312, or the suction nozzles 311 are closed at the same time to release the adsorption of the heat-sealing film 3110, so that the heat-sealing film 3110 and the reagent strip 10 can be completed. The relative positions of the suction nozzles 311 and the heat-sealing head 312 are set in this way, which is suitable for heat sealing of products that need to leave unattached sides to facilitate tearing of the heat-sealing film 3110.

[0081] In this embodiment, the heat sealing head 312 is provided with a through hole 3121, and the suction nozzle 311 passes through the through hole 3121, that is, the suction nozzle 311 is embedded in the heat sealing head 312, and the suction nozzle 311 turns on the vacuum to suck up the heat sealing film 3110, and the heat sealing film 3110 is transferred and placed on the reagent strip 10, and then the heat sealing head 312 is pressed down for heat sealing and bonding. Because the suction nozzle 311 passes through the heat sealing head 312, the heat sealing head 312 can press down for heat sealing and bonding while the suction nozzle 311 places the heat sealing film 3110. The heat sealing film 3110 is always adsorbed by the suction nozzle 311 before being pressed down by the heat sealing head 312, and there is no need to lift and remove the suction nozzle 311 first, and there will be no deviation. The relative position accuracy with the reagent strip 10 is high, thereby making the product yield high.

[0082] The suction nozzle 311 is used to suck the heat-sealing film 1 , and it should be ensured that the suction nozzle 311 can stably suck the heat-sealing film 1 and should not cause damage such as wrinkles to the heat-sealing film 3110 .

[0083] In this embodiment, the number of suction nozzles 311 is multiple, and multiple suction nozzles 311 are arranged in rows and columns. Those skilled in the art can understand that the scale of the rows and columns of the suction nozzles 311 should be set according to actual needs and conditions, for example, the number of rows should be the number of reagent strips 10 that can be heat-sealed at the same time at the workstation (a row of suction nozzles 311 sucks a piece of heat-sealing film 3110) or an integer multiple of the number of reagent strips 10 that can be heat-sealed at the same time at the workstation (multiple rows of suction nozzles 311 suck a piece of heat-sealing film 3110); the number of columns should be set according to the size specifications of the heat-sealing film 3110, and the suction nozzles 311 of appropriate density are set to ensure that there is enough suction to suck up the heat-sealing film 3110, while avoiding the inconvenience caused by the small spacing of the suction nozzles 311 during the heat-sealing process. In this embodiment, the number of reagent strips 10 that can be heat-sealed at the same time at the workstation is four, and the suction nozzles 311 are provided with four rows and six columns, that is, a piece of heat-sealing film 3110 is sucked by six suction nozzles 311, which effectively avoids wrinkles on the heat-sealing film 3110 while ensuring sufficient suction for sucking the heat-sealing film 3110.

[0084] The heat sealing head 312 is used to heat seal and press the heat sealing film 3110 onto the reagent strip 10 , so the heat sealing head 312 should be able to reciprocate in a straight line along the heat pressing direction.

[0085] In this embodiment, the heat sealing mechanism 100 further includes a first driving mechanism 3131, which is used to drive the heat sealing head 312 so that the heat sealing head 312 can reciprocate along a straight line in the heat pressing direction, thereby completing the heat pressing bonding.

[0086] The heat-sealing film 3110 should be evenly pressed by the heat-sealing head 312 when heat-sealing it onto the reagent strip 10 to ensure the heat-sealing quality.

[0087] In this embodiment, the first driving mechanism 3131 is connected to the heat sealing head 312 through a plurality of guide posts 314, and the plurality of guide posts 314 are arranged in an array, and a first spring 3141 is sleeved on the guide posts 314. The guide posts 314 guide the heat sealing head 312 to ensure the posture stability of the heat sealing head 312 during heat sealing. Therefore, the array arrangement of the guide posts 314 can be arranged according to the shape of the heat sealing head 312, and the posture stability of the heat sealing head 312 is ensured under the coordinated action of the guide posts 314 at multiple positions; at the same time, when the first driving mechanism 3131 drives the heat sealing head 312 to perform heat sealing, the first spring 3141 on the guide post 314 applies thrust to the heat sealing head 312. When the pressure of the heat-sealing head 312 is uneven at various places, resulting in a flatness error on the heat-sealing plane, the thrust of the first spring 3141 on each guide post 314 on the heat-sealing head 312 will also be different due to different degrees of deformation, and the raised side of the heat-sealing head 312 will continue to approach the heat-sealing film 3110 due to a greater thrust, until the pressure of the heat-sealing head 312 is uniform at various places. Through the first spring 3141 on the guide post 314, the problem of heat-sealing flatness error caused by the height difference of the reagent strip 10 and other reasons during the heat-sealing pressing process of the heat-sealing head 312 can be effectively solved, the heat-sealing quality is guaranteed, and the uniformity of the product appearance is also high. It can be understood by those skilled in the art that the guide post 314 can be directly connected to the heat-sealing head 312, or it can be indirectly connected to the heat-sealing head 312. In this embodiment, the guide column 314 is indirectly connected to the heat sealing head 312, and the heat sealing head 312 is arranged on the heat sealing head mounting block 3122. The guide column 314 is connected to the heat sealing head mounting block 3122. Such an arrangement can reduce the direct processing of the heat sealing head 312, increase the stability of the heat sealing head 312, and facilitate the inspection and replacement of the heat sealing head 312.

[0088] The suction nozzle 311 is used to suck the heat-sealing film 3110 , and therefore, the suction nozzle 311 should be able to reciprocate in the same linear direction as the heat-sealing pressure head 312 .

[0089] In this embodiment, the heat sealing mechanism 100 also includes a second driving mechanism 3132, and the second driving mechanism 31 is used to drive the suction nozzle 311 so that the suction nozzle 311 can reciprocate in the same straight line direction as the heat sealing head 312, that is, the suction nozzle 311 can reciprocate in the through hole 3121 of the heat sealing head 312 to place the heat sealing film 3110 on the reagent strip 10.

[0090] During the discharge process of the heat-sealing film 3110 , the placement height of the heat-sealing film 3110 on each reagent strip 10 should be the same to ensure the heat-sealing quality and the consistency of the appearance of the product after heat sealing.

[0091] In this embodiment, the second driving mechanism 3132 is connected to the suction nozzle 311 through a plurality of guide posts 314, and the plurality of guide posts 314 are arranged in an array, and the second spring 3142 is sleeved on the guide post 314. In this way, the same as the working principle of the guide post 314 and the first spring 3141 on the heat sealing head 312, multiple heat sealing films 3110 can be evenly placed on each reagent strip 10 at the same height to ensure the heat sealing effect and the appearance of the product after heat sealing. In this embodiment, a plurality of suction nozzles 311 are arranged on the suction nozzle mounting block 3111, and the second driving mechanism 3132 is connected to the suction nozzle mounting block 3111 through a plurality of guide posts 314. It can be understood by those skilled in the art that the pressure on the suction nozzle 311 when placing the heat sealing film 3110 and the pressure on the heat sealing head 312 when performing heat sealing and pressing are generally quite different, so the pressure that the second spring 3142 needs to provide to the suction nozzle 311 and the pressure that the first spring 3141 needs to provide to the heat sealing head 312 should also be quite different. Therefore, the first spring 3141 and the second spring 3142 should be selected with springs of different specifications. When heat-sealing and pressing certain products, the pressures required to be provided by the first spring 3141 and the second spring 3142 may be similar. In this case, the first spring 3141 and the second spring 3142 may also be selected with springs of the same specifications.

[0092] The suction nozzle 311 is used to suck the heat-sealing film 3110, and should be able to complete the material collection and loading of the heat-sealing film 3110, that is, the suction nozzle 311 can move in a height plane to the top of the material collection point of the heat-sealing film 3110, and return to the top of the loading point after the material collection is completed. Since the suction nozzle 311 is embedded in the heat-sealing head 312, the heat-sealing head 312 should be translated synchronously with the suction nozzle 311 during the material collection and loading process of the suction nozzle 311 to avoid interference between the suction nozzle 311 and the heat-sealing head 312.

[0093] In some embodiments, the first driving mechanism 3131 and the second driving mechanism 3132 can respectively drive the heat sealing head 312 and the suction nozzle 311 to translate synchronously, so as to drive the suction nozzle 311 to complete the taking and loading of the heat sealing film 3110 .

[0094] In this embodiment, the heat sealing mechanism 100 further includes a third driving mechanism 3133, which is used to synchronously drive the heat sealing head 312 and the suction nozzle 311, and the driving direction of the third driving mechanism 3133 is perpendicular to the driving direction of the first driving mechanism 3131. Specifically, the first driving mechanism 3131 and the second driving mechanism 3132 are both arranged on the third driving mechanism 3133, and the third driving mechanism 3133 drives the first driving mechanism 3131 and the second driving mechanism 3132 to translate, thereby driving the heat sealing head 312 and the suction nozzle 311 to translate. With such a configuration, the structure of each driving mechanism is simple, the driving method is simple, and the failure rate is reduced. When the heat sealing structure 100 in this embodiment performs heat sealing and pressing, the suction nozzle 311 is first driven horizontally to the top of the material taking place by the third driving mechanism 3133; then the suction nozzle 311 is driven vertically downward to the place where the heat sealing film 3110 can be sucked up by the second driving mechanism 3132, the vacuum of the suction nozzle 311 is turned on, and the heat sealing film 3110 is sucked up; then the suction nozzle 311 is driven vertically upward to a suitable position by the second driving mechanism 3132, and then driven horizontally to the top of the material feeding place by the third driving mechanism 3133, and the suction nozzle 311 is driven vertically downward by the second driving mechanism 3132 until the heat sealing film 3110 is placed on the reagent strip 10, and then the heat sealing head 312 is driven downward by the first driving mechanism 3131. When heat sealing and pressing, the suction nozzle 311 vacuum is closed, and after the heat sealing and pressing is completed, the heat sealing head 312 and the suction nozzle 311 are driven to reset by the first driving mechanism 3131 and the second driving mechanism 3132, and a heat sealing and pressing is completed.

[0095] The heat sealing head 312 is used to heat seal and press the heat sealing film 3110, so the heat sealing head 312 should have a suitable temperature to ensure the heat sealing quality.

[0096] In this embodiment, a heating element 3123 is provided on the heat sealing head 312, and several heating elements 3123 are embedded in the heat sealing head 312 to ensure uniform temperature at all locations of the heat sealing head 312 and ensure heat sealing quality. The heating element 3123 can be a part that can be used for heating, such as a thermal resistor, an electric heating film, etc., and is not limited here.

[0097] In this embodiment, the heat sealing head 312 is made of copper, which has good thermal conductivity, uniform temperature, and good heat sealing quality. According to the materials of the heat sealing film 3110 and the reagent strip 10, different temperatures can be set for the heat sealing head 312 to ensure the heat sealing quality. In this embodiment, the heat sealing film 3110 is an aluminum film.

[0098] To ensure that the suction nozzle 311 can stably absorb the heat-sealing film 3110, in this embodiment, the suction port of the suction nozzle 311 is elliptical, and a suction hole is opened in the center of the elliptical suction port to increase the contact area between the suction port and the heat-sealing film 3110, so that the suction nozzle 311 can absorb the heat-sealing film 3110 more stably.

[0099] The film material punching mechanism 32 is provided with a film taking port 321, and the heat-sealing film 3110 punched by the film material punching mechanism 32 is placed below the film taking port 321. When the heat-sealing mechanism 31 takes the heat-sealing film 3110, the suction nozzle 311 is extended into the film taking port 321 through the cooperation of the third driving mechanism 3133 and the second driving mechanism 3132 to suck the heat-sealing film 3110, and the subsequent heat-sealing test strip 10 operation is completed.

[0100] The reagent strips 10 sold on the market generally need to have a label or some product information on the outer shell of the reagent strip 10 .

[0101] like Figure 1 As shown, the reagent strip filling device 100 in this embodiment also includes a coding mechanism 8 and a labeling mechanism 9, which are arranged between the film sealing mechanism 3 and the detection mechanism 4. The coding mechanism 8 is used to perform coding processing on the reagent strip 10 after the film sealing is completed, and the labeling mechanism 9 is used to perform labeling processing on the reagent strip 10 after the film sealing is completed. The detection mechanism 4 is also used to detect the coding quality and labeling quality of the reagent strip 10. In this embodiment, the detection mechanism 4 detects the reagent strip 10 by visual detection, and the detection mechanism 4 includes a CCD detection component.

[0102] The unloading mechanism 5 is used to load and unload the reagent strip 10 from the material seat 7 .

[0103] like Fig.26 As shown, the unloading mechanism 5 in this embodiment includes a second manipulator 51 and an unloading transport line 52. The second manipulator 51 is used to move the reagent strip 10 that has been tested by the detection mechanism 4 from the material seat 7 to the unloading transport line 52, and the unloading transport line 52 is used to transport the reagent strip 10 to the next assembly line or the storage place of the reagent strip 10. If the product is found to be unqualified in quality (sealing quality, coding quality and labeling quality) by the detection mechanism 4, a unloading mechanism 5 with a different transportation destination can be set at the detection mechanism 4, or a plurality of unloading transport lines 52 can be set on the unloading mechanism 7, which are used to transport qualified reagent strips 10 and unqualified reagent strips 10 respectively, and sorted by the second manipulator 51.

[0104] According to the reagent strip filling equipment 100 in the above embodiment, through the action of the circulating transport platform 6, the material seat 7 that completes the loading of the reagent strip 10 at the loading mechanism 1 can sequentially pass through the filling mechanism 2, the film sealing mechanism 3, and the detection mechanism 4 to reach the unloading mechanism 5, and complete the filling, film sealing, detection and unloading of the reagent strip 10. After unloading at the unloading mechanism 5, the material seat 7 can return to the loading mechanism 1 to reload the reagent strip 10, so that the automation of the production process of the reagent strip 10 can be realized, the production capacity can be improved, and the labor cost can be reduced.
