[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] See Figure 1 This invention provides a reagent card assembly device for the automatic assembly of reagent cards. It automatically installs blister packs and electrode cards into a housing structure enclosed by an upper and lower cover. Specifically, it includes an assembly line 1, an electrode card feeder 2, a blister pack feeder 3, an upper cover feeder 4, and a lower cover feeder 5. The electrode card feeder 2, blister pack feeder 3, upper cover feeder 4, and lower cover feeder 5 all transfer their corresponding materials to the assembly line 1 via a transfer structure, thereby achieving the overall assembly of the reagent cards. The entire process is fully automated, ensuring not only the quality of the assembled reagent cards but also very high production efficiency.

[0053] See Figure 1 as well as Figure 2The upper cover feeder 4 and the lower cover feeder 5 use the same feeding method. For example, the upper cover feeder 4 includes an upper cover buffer bin 41, an upper cover vibrating plate module 42, and an upper cover conveyor line 43. The upper cover buffer bin 41 is mainly used to stack upper cover materials. The upper covers in the upper cover buffer bin 41 can enter the upper cover vibrating plate module 42. The upper covers can smoothly enter the upper cover vibrating plate module 42 from the upper cover buffer bin 41 by their own gravity. The upper cover vibrating plate module 42 adopts the principle of vibrating plate and conveys the upper covers to the upper cover conveyor line 43 in an orderly manner by vibration. At the end of the upper cover conveyor line 43, the upper covers in the upper cover conveyor line 43 can be grabbed by a robot and placed in a designated position for assembly. Similarly, the lower cover feeder 5 includes a lower cover buffer bin 51, a lower cover vibrating plate module 52, and a lower cover conveyor line 53. The lower cover buffer bin 51 is mainly used to store the lower covers. The lower covers in the lower cover buffer bin 51 can enter the lower cover vibrating plate module 52. The lower cover vibrating plate module 52 adopts the principle of vibrating plate, which can transport the lower covers to the lower cover conveyor line 53 in an orderly manner. At the end of the lower cover conveyor line 53, the lower covers in the lower cover conveyor line 53 can be picked up by a robot and placed in a designated position for assembly.

[0054] The electrode card feeder 2 includes a hopper loading module 21, a cutting module 22, a detection module, and an electrode card conveying line 23. In this invention, the electrode cards prepared in the aforementioned processes are usually distributed in an array on the same electrode sheet, with each electrode card as a whole. However, the electrode cards used for reagent cards are single individuals, thus requiring the cutting module 22 to divide the electrode cards within the electrode sheet. Based on this, multiple sets of electrode sheets are stacked in the hopper loading module 21. The stacked electrode sheets can be picked up by a robotic arm and transported sequentially from top to bottom, or they can be transported sequentially from bottom to top using a transport rack. The electrode sheets are transported to the cutting module 22, which typically uses a laser cutter. After being positioned by a camera, the laser cutter laser-cuts the electrode cards on the electrode sheets. Then, the robotic arm picks up the cut single electrode cards and places them into a tray. When the tray is full of individual electrode cards, the inspection module performs quality inspection on the electrode cards in the tray, mainly using visual inspection. When a defective product is detected, the corresponding electrode card is removed, and electrode cards are replenished into the tray. When all the electrode cards in the tray are good, the robotic arm picks up all the electrode cards in the tray and transfers them to the electrode card conveyor line 23. The electrode cards are then sequentially transferred to the assembly line 1 via the electrode card conveyor line 23.

[0055] In a preferred embodiment, assembly line 1 uses double-sided adhesive to bond and fix the electrode card, blister pack, upper cover and lower cover, thereby realizing the assembly of the reagent card.

[0056] See Figure 3Based on the above assembly method, this embodiment of the invention provides an assembly line 1, including a double-sided adhesive feeding device 11, used to supply double-sided adhesive to the assembly line 1, thereby assembling various materials through the double-sided adhesive. The double-sided adhesive feeding device 11 includes a double-sided adhesive unwinding mechanism 12, a cutting mechanism 13, a backing paper peeling mechanism 14, a backing paper winding mechanism 15, and a double-sided adhesive conveying line 16, which are arranged sequentially along the moving direction of the double-sided adhesive backing paper. The double-sided adhesive conveying line 16 supports the double-sided adhesive and moves along the length extension direction of the double-sided adhesive conveying line 16. The double-sided adhesive is in roll form. The double-sided adhesive is installed on the double-sided adhesive unwinding mechanism 12, and the outer end of the double-sided adhesive backing paper is connected to the backing paper winding mechanism 15. The backing paper passes sequentially through the cutting mechanism 13 and the backing paper peeling mechanism 14. Throughout the process, the backing paper is a continuous structure, while the adhesive layer on the backing paper is cut at the cutting mechanism 13, and the backing paper and adhesive layer are separated at the backing paper peeling mechanism 14. Multiple sets of limiting grooves 17 are distributed on the double-sided tape conveyor line 16. Each set of limiting grooves 17 is distributed at intervals along the length of the double-sided tape conveyor line 16, and the double-sided tape is located in each set of limiting grooves 17.

[0057] See Figure 3 as well as Figure 4 In this embodiment, the double-sided adhesive unwinding mechanism 12 is a follower mechanism. The follower shaft 18 of the double-sided adhesive unwinding mechanism 12 passes through the central shaft hole of the double-sided adhesive roll. The double-sided adhesive roll can rotate relative to the axis of the follower shaft 18. The bottom paper winding mechanism 15 is a drive mechanism. The outer end of the bottom paper is connected to the drive shaft 19 of the bottom paper winding mechanism 15. Under the drive of the motor, the drive shaft 19 can drive the outer end of the bottom paper to rotate around its own axis, so that the bottom paper can gradually wind onto the drive shaft 19, thereby achieving the purpose of winding. At the same time, it can pull the follower shaft 18 on the double-sided adhesive unwinding mechanism 12 to rotate synchronously. The double-sided adhesive roll is gradually unwound. When the double-sided adhesive roll is completely unwound, it is only necessary to replace it with a new double-sided adhesive roll onto the double-sided adhesive unwinding mechanism 12. In a preferred embodiment, the double-sided adhesive unwinding mechanism 12 is also equipped with a motor 110 (damping motor), which is connected to the follower shaft 18 for transmission. The motor 110 can play a role in tensioning and damping the backing paper.

[0058] See Figure 1 as well as Figure 3The cutting mechanism 13 provided by this invention can be a laser cutting machine, which is located near the double-sided adhesive unwinding mechanism 12. The double-sided adhesive enters the laser cutting machine horizontally with the adhesive layer facing upwards. The laser cutting machine performs laser cutting on the double-sided adhesive at a certain frequency. During cutting, the laser only acts on the adhesive layer, that is, it cuts the adhesive layer of the double-sided adhesive at equal intervals without affecting the backing paper. The broken adhesive layer moves synchronously with the backing paper. When the assembly line 1 provided in this embodiment is applied to the reagent card assembly equipment, after the adhesive layer is cut, each independent adhesive layer corresponds to a separate reagent card product. Part of the reagent card material can be bonded to the adhesive layer. Specifically, the electrode card and the lower cover can be bonded to the upper surface of the adhesive layer. The bonding process is as follows: first, a robotic arm is used to bond the electrode card on the electrode card conveying line 24 to the corresponding position of the adhesive layer. Then, the lower cover conveyed by the lower cover feeder 5 is also bonded to the upper surface of the adhesive layer by the robotic arm. The lower cover covers the entire upper surface of this section of the adhesive layer. The aforementioned electrode card is located between the lower cover and the upper surface of the adhesive layer. In addition, when laser cutting machines cut adhesive layers, they do not simply cut the adhesive layer. Each segment of adhesive layer needs to be cut into the corresponding shape according to the actual product requirements. Furthermore, there should be a certain distance between adjacent segments of adhesive layer to avoid interference between adjacent segments during assembly.

[0059] In a preferred embodiment, two parallel adhesive lines can be formed along the moving direction of the base paper. That is, along the width direction of the double-sided adhesive, it is cut into two parallel adhesive layers by a laser cutting machine. Of course, there should also be a certain distance between these two adhesive layers. Thus, the robotic arm can simultaneously grasp two or four electrode cards and bond them to the corresponding adhesive layers at the same time. Similarly, the lower cover can also grasp multiple cards and assemble them synchronously, greatly improving the bonding and assembly efficiency.

[0060] After the materials are bonded and assembled onto the upper surface of the adhesive layer, they must first pass through the pressing module 111. The pressing module 111 includes a gate-shaped frame through which the double-sided adhesive passes. A pressing cylinder is installed on the inner top side of the gate-shaped frame. The pressing cylinder is vertically positioned. When the assembled adhesive layer moves directly below the pressing cylinder, the pressing cylinder extends to press down the lower cover, ensuring the adhesion between the lower cover and the upper surface of the adhesive layer. A pressure plate should be installed at the lower end of the pressing cylinder, contacting the outer surface of the lower cover.

[0061] See you again Figure 3 as well as Figure 4After being pressed, the double-sided adhesive enters the backing paper peeling mechanism 14 to separate the adhesive layer from the backing paper. The backing paper peeling mechanism 14 includes a peeling plate 112, the upper surface of which is at the same height as or close to the lower surface of the adhesive layer. A guide roller 113 is horizontally arranged directly below the double-sided adhesive conveyor line 16, close to the feed side of the peeling plate 112. The backing paper is connected to the backing paper winding mechanism 15 through the guide roller 113. When the adhesive layer moves synchronously with the backing paper to the feed side of the peeling plate 112, the backing paper turns under the action of the guide roller 113 and continues to move downwards from the double-sided adhesive conveyor line 16. However, the adhesive layer cannot turn downwards synchronously with the backing paper due to the resistance of the feed side of the peeling plate 112. Therefore, the adhesive layer can only continue to move forward horizontally onto the peeling plate 112 under the action of the backing paper until the adhesive layer is completely on the peeling plate 112, and the backing paper and the adhesive layer are completely separated. Of course, the adhesion between the peeling plate 112 and the adhesive layer is poor, and it can be easily peeled off by a robotic arm.

[0062] See Figure 4 The structure of the peeling plate 112 is optimized, with two blocks 114 arranged opposite each other on its upper surface. The two blocks 114 are elongated and extend along the moving direction of the adhesive layer. The two blocks 114 form a limiting groove on the upper surface of the peeling plate 112 to restrict the adhesive layer detached from the backing paper to move only within the limiting groove. In addition, when the adhesive layer with the material is attached moves to the peeling plate 112, it can instruct the robot to pick up the adhesive layer and the assembly material on the peeling plate 112 and place them in a designated position to realize the subsequent assembly of the materials. For example, when assembly line 1 is used for reagent card assembly, a semi-finished reagent card is assembled on the peeling plate 112. Subsequently, the blister pack and the top cover should be assembled to the lower surface of the adhesive layer to assemble the finished reagent card. After the robotic arm transfers the aforementioned adhesive layer and materials, a waste adhesive layer remains on the stripping plate 112. Since the waste adhesive layer is a continuous whole, the assembly line 1 should also be equipped with a waste adhesive collection mechanism 115, which is located below the stripping plate 112. The waste adhesive collection mechanism 115 also adopts a winding structure, which includes a waste adhesive take-up shaft 116. The waste adhesive is wound up by rotating the waste adhesive take-up shaft 116. Of course, the waste adhesive collection mechanism 115 should also include a guide roller 117, which is used to turn and tension the waste adhesive layer. In addition, a waste adhesive full sensor 118 can be added, which is set close to the guide roller 117.

[0063] In a preferred embodiment, a baffle rod 119 is also provided on the discharge side of the peeling plate 112. There is a gap between the baffle rod 119 and the discharge side edge of the peeling plate 112, and the waste glue layer extends downward to the guide roller 117 through the gap.

[0064] See you again Figure 1 as well as Figure 2Furthermore, for the assembly of reagent cards, assembly line 1 should also include a blister packing module 120 and a top cover packing module 121. The blister packing module 120 is the upper station of the top cover packing module 121. The blister packing module 120 is mainly used to assemble the finished blister packs to the corresponding positions on the lower surface of the adhesive layer, while the top cover packing module 121 is used to assemble the top cover to the lower surface of the adhesive layer, and the top cover covers the lower surface of the adhesive layer, with the blister packs located between the top cover and the lower surface of the adhesive layer.

[0065] See Figure 1-3 The structure of the blister packing module 120 is refined, including a first rotary table 122. The blister feeder 3 is connected to the first rotary table 122 via a blister conveyor line 330. The blister feeder 3 transports finished blister packs to the end of the blister conveyor line 330. The finished blister packs are placed on the fixtures of the first rotary table 122 by a robot arm 124. Then, another robot arm 125 picks up the semi-finished reagent cards from the stripping plate 112 and places them onto the blister packs. The blister packs are bonded to the corresponding positions of the lower surface of the adhesive layer, and the lower cover is pressed down by a pressure plate to fix the blister packs to the lower surface of the adhesive layer. The blister packing module 120 is in the form of a rotary table with multiple fixtures. By rotating, the fixtures are circulated and transferred between different workstations. The blister packing action, the assembly action of the blister packs and semi-finished reagent cards, the pressure action, and the unloading action can all be completed independently, effectively ensuring the working efficiency of the blister packing module 120.

[0066] See you again Figure 1 as well as Figure 2 The structure of the top cover feeding module 121 is refined, including a second rotary table 123. A top cover feeder 4 is connected to the second rotary table 123 via a top cover conveyor line 43. The top cover feeder 4 transports the top cover to the end of the top cover conveyor line 43. A robotic arm 126 places the top cover on a fixture on the second rotary table 123. Another robotic arm 127 picks up the semi-finished product assembled by the blister packing module 120 and places it below the top cover. The top cover is bonded to the lower surface of the adhesive layer, and a pressure plate presses down on the bottom cover, fixing the top cover to the lower surface of the adhesive layer. The working mode of the top cover feeding module 121 is similar to that of the blister packing module 120. After the top cover is assembled, a reagent card is formed. After testing, the finished reagent card is unloaded through the unloading module 6. The unloading module 6 mainly includes an unloading conveyor line, where qualified reagent cards are transferred by robotic arms.

[0067] See Figure 5 This invention provides a blister feeder 3, which can be applied to the assembly equipment described above. The blister feeder 3 can be used to prepare and fill blister packs.

[0068] In this invention, the blister feeder 3 includes a tape unwinding mechanism 31, a blister forming mechanism 32, a filling mechanism 33, a sealing mechanism 34, a tape winding mechanism 35, and a blister forming line 36. The material moves along the blister forming line 36. The aforementioned five components are arranged sequentially along the blister forming line 36. The material here is the blister material, which is usually aluminum foil. Due to the unwinding and winding method, the material is a continuous aluminum foil roll. The aluminum foil roll to be processed is installed on the tape unwinding mechanism 31. The outer end of the aluminum foil roll passes through the blister forming mechanism 32, the filling mechanism 33, and the sealing mechanism 34 in sequence and is connected to the tape winding mechanism 35. The strip unwinding mechanism 31 is a follower mechanism. The follower shaft 328 of the strip unwinding mechanism 31 passes through the central shaft hole of the aluminum foil roll. The aluminum foil roll can rotate relative to the axis of the follower shaft 328. The strip winding mechanism 35 is a drive mechanism. The outer end of the aluminum foil roll is connected to the drive shaft 37 of the strip winding mechanism 35. Under the drive of the motor, the drive shaft 37 can drive the outer end of the aluminum foil roll to rotate around its own axis, so that the aluminum foil roll can gradually wind onto the drive shaft 37 to achieve the purpose of winding. At the same time, it pulls the aluminum foil roll on the strip unwinding mechanism 31 to rotate synchronously around the axis of the follower shaft 328. The aluminum foil roll at the strip unwinding mechanism 31 is gradually unwound. When the aluminum foil roll on the strip unwinding mechanism 31 is completely unwound, another aluminum foil roll only needs to be placed on the follower shaft 328. In the preferred embodiment, the strip unwinding mechanism 31 is also equipped with a motor 38 (damping motor), which is connected to the follower shaft 328 for transmission. The motor 38 can play a role in tensioning and damping the aluminum foil.

[0069] The blister forming mechanism 32 is used to form blister packs on continuous aluminum foil. The blister packs should have openings. When they move to the filling mechanism 33, the filling mechanism 33 can inject liquid into them through the openings. After the liquid injection is completed, the sealing mechanism 34 can close the openings, thereby achieving the purpose of sealing the blister packs. The blister forming line 36 includes multiple rollers, each of which can rotate around its own axis. Some rollers are used to tension the aluminum foil, some to support the aluminum foil, and some to press against the aluminum foil. A set of traction rollers 39 is also provided. The aluminum foil passes between these traction rollers 39. Both traction rollers 39 are driven to rotate by servo motors. The rotation of the traction rollers 39 generates traction force on the aluminum foil, and the traction rollers are close to the strip winding mechanism 35.

[0070] See Figure 6Specifically, the blister forming mechanism 32 forms different shapes and sizes according to actual needs, including a pre-forming component 310, a folding component 311, and a sealing component 312. The pre-forming component 310 uses a stamping forming device 313, and the stamping die 315 is determined according to the shape and size of the blister. For example, the stamping die 315 can be hemispherical. The stamping die 315 is located above the stamping base 314, and the aluminum foil is located on the stamping base 314. Two stamping dies 315 are provided and arranged side by side along the width direction of the aluminum foil. Of course, the shape and size of the two stamping dies 315 can be the same or different, and they are also determined according to the shape of the blister. Under the action of the vertical cylinder, the two stamping dies 315 simultaneously press down on the aluminum foil at a certain frequency, thereby forming two rows of grooves (along the length direction of the aluminum foil) on the aluminum foil, and the two rows of grooves correspond one-to-one.

[0071] During the preforming stage, the aluminum foil moves horizontally on the stamping base 314. When the stamped aluminum foil with grooves enters the folding assembly 311, the folding assembly 311 can fold the horizontal aluminum foil in half. The fold line is the center line of the aluminum foil and extends along the length of the aluminum foil. After the aluminum foil is folded by the folding assembly 311, the two folded parts of the aluminum foil fit together perfectly, and the corresponding two grooves can surround and form a blister structure.

[0072] See Figure 6 as well as Figure 7Specifically, the folding assembly 311 includes a folding base 316 and a folding piece 317. A folding groove 318 is formed on the surface of the folding base 316, extending through the folding base 316 along the moving direction of the aluminum foil. At least a portion of the structure of the folding piece 317 extends into the folding groove 318, and the fold line of the aluminum foil passes through the folding groove 318. During folding, the aluminum foil is first manually folded along the fold line into the folding groove 318, with the folding piece 317 positioned between the two folded parts of the aluminum foil. Thus, as the aluminum foil passes through the folding groove 318 sequentially, it is folded in half. At this time, the horizontal aluminum foil is folded into a vertical state after entering the folding groove 318. The folding groove 318 tapers along the moving direction of the aluminum foil on its inlet side, meaning the inlet size is relatively large, facilitating the placement of the folded aluminum foil into the folding groove 318. The width of the groove on the outlet side of the folding groove 318 is slightly greater than the thickness of the two layers of aluminum foil. The aforementioned flap 317 is located near the discharge side of the folding groove 318, and the portion of flap 317 extending into the folding groove 318 is close to the bottom of the folding groove 318. The gap between the two is slightly larger than the thickness of the aluminum foil. The portion of the aluminum foil corresponding to the folding line passes sequentially between flap 317 and the bottom of the folding groove 318. Flap 317 can form a folding line to press the aluminum foil, thereby optimizing the folding effect of the aluminum foil. In this embodiment, the horizontal aluminum foil is vertically folded by the folding component 311, that is, the aluminum foil is in a vertical state after folding. Thus, the aluminum foil is horizontal before the folding component 311 and vertical after folding. Therefore, the follower shaft 36 of the strip unwinding mechanism 31 and all rollers before the folding component 311 are horizontally arranged, while the drive shaft 37 of the strip winding mechanism 35 and all rollers after the folding component 311 are vertically arranged.

[0073] In the preferred embodiment, the flap 317 is a circular structure, and its center can be rotatably mounted on a bracket 329 via a pivot. Thus, when the aluminum foil passes under the flap 317, the aluminum foil can drive the flap 317 to rotate around the axis of the pivot. That is, there is rolling friction between the aluminum foil and the flap 317, which can reduce the damage to the aluminum foil caused by the flap 317.

[0074] Furthermore, the folding assembly 311 also includes a set of extrusion rollers 319. The two extrusion rollers 319 are vertically arranged, forming an extrusion groove between them for the folded aluminum foil to pass through. They are located on the discharge side of the folding seat 316, and the folded aluminum foil enters the extrusion groove between the two extrusion rollers. The roller shafts of both extrusion rollers are stepped shafts, and the shaft diameter at both ends is larger than the shaft diameter at the middle. As a result, the width of the middle section of the extrusion groove is greater than the dimensions at both ends, so that the middle section of the extrusion groove can allow the portion of the aluminum foil corresponding to the groove (the portion of the groove protrudes outward after folding) to pass through. The upper and lower ends of the folded aluminum foil pass through the upper and lower ends of the extrusion groove respectively, and a compression effect is formed, further ensuring the folding effect.

[0075] In addition, a pressure roller 320 is provided between the folding seat 316 and the preforming component 310. The pressure roller 320 is horizontally positioned and has a certain distance from the folding seat 316 to control the level of the aluminum foil. As a result, the aluminum foil between the pressure roller 320 and the folding seat 316 tilts upwards with increasing amplitude in the direction close to the folding seat 316 until it enters the folding groove 318 and is folded in half, while the aluminum foil between the pressure roller 320 and the preforming component 310 remains horizontal.

[0076] See Figure 6 as well as Figure 8 After being folded by the folding component 311, the aluminum foil enters the encapsulation component 312. The encapsulation component 312 is used to seal the blister formed by the two grooves on the folded aluminum foil. Specifically, the encapsulation component 312 uses heat sealing to seal the blister formed by the two grooves. The encapsulation component 312 includes two vertically arranged heat sealing plates 321, which are arranged opposite to each other. Both heat sealing plates 321 can move horizontally under the action of the driving component. During horizontal movement, they move away from or closer to each other. The blister forming line 36 passes between the two heat sealing plates 321. Both heat-sealing plates 321 are provided with mold cavities that mate with the protrusions on the folded aluminum foil. The heating area of ​​the heat-sealing plate 321 is annular around the mold cavity, and the annulus is broken at the upper end. Thus, when the blister pack moves to the position corresponding to the mold cavity, the driving component can drive the two heat-sealing plates 321 to move closer together, so that the protruding part of the blister pack is exactly located inside the mold cavity. At the same time, the heating areas of the two heat-sealing plates 321 clamp the aluminum foil to achieve heat sealing of the two grooves of the blister pack. Since the upper end of the heating area is broken, the upper end of the heat-sealed blister pack has an opening, that is, the blister pack is not completely sealed. Multiple sets of packaging components 312 can be provided. Multiple sets of packaging components 312 can heat seal multiple blister packs on the aluminum foil, or each packaging component 312 has multiple mold cavities on its heat-sealing plate 321, and the packaging component 312 can heat seal multiple blister packs simultaneously.

[0077] The filling mechanism 33 is located on the discharge side of the encapsulation component 312. The heat-sealed blister pack enters the filling mechanism 33, and liquid is injected into the inner cavity of the blister pack through the filling mechanism 33. The filling mechanism 33 includes a liquid source, a liquid injection head 322, and a linear motion component 323. The liquid injection head 322 is mounted on the linear motion component 323. The linear motion component 323 can control the liquid injection head to move in the vertical direction. A liquid pump can draw liquid from the liquid source to the liquid injection head, and then the liquid injection head injects it into the blister pack.

[0078] Multiple injection heads 322 can be arranged side-by-side on the linear motion component 323, all located directly above the blister forming line 36. Under the action of the linear motion component 323, multiple blister packs can be injected simultaneously. When the heat-sealed blister pack moves directly below the injection head 322, the cylinder of the linear motion component 323 drives the injection head 322 downwards and into the inner cavity through the upper opening of the blister pack. The liquid pump then injects a measured amount of liquid into the blister pack. After injection is complete, the cylinder of the linear motion component 323 controls the injection head to move upwards and reset. The injection head 322 can be a filling injection needle. The linear motion component 323 can also control the horizontal movement of the injection head 322, which can transfer the injection head 322 to the liquid source. The liquid pump can directly draw liquid into the injection head 322. The linear motion component 323 then controls the injection head to extend into the blister pack again, and the liquid in the injection head 322 can be directly injected into the blister pack.

[0079] After the filling mechanism 33 completes the liquid injection, the sealing mechanism 34 seals the blister, sealing the inner cavity of the blister. The sealing mechanism 34 and the filling mechanism 33 can be arranged in two ways: for example, the sealing mechanism 34 can be located on the discharge side of the filling mechanism 33, with both being independent workstations, and the blister moving to the sealing mechanism 34 after liquid injection; or the sealing mechanism 34 and the filling mechanism 33 can be located at the same workstation, with the aluminum foil remaining stationary after the filling mechanism 33 injects liquid into the blister, and the sealing mechanism 34 directly sealing the blister. The sealing mechanism 34 uses the same working method as the packaging component 312, sealing the blister through heat sealing. Their overall structures are similar, using two heat-sealing plates for heat sealing, only the heating area structure differs; the heating area of ​​the sealing mechanism 34 is only for the opening of the aluminum foil.

[0080] In a preferred embodiment, the blister feeder 3 should also include a blister cutting mechanism 324, which can cut the blister after liquid injection and sealing from the aluminum foil. The material strip winding mechanism 35 is mainly used to wind up the aluminum foil waste after the blister is cut.

[0081] See Figure 8 as well as Figure 9The blister cutting mechanism 324 is refined and adopts a punching method. It includes a punching component 325, a translation component 326, a transfer component, and a fixing component 327. The punching component 325 and the fixing component 327 are arranged opposite to each other. The blister forming line 36 is located between the punching component 325 and the fixing component 327, that is, the aluminum foil moves between the two. In addition, the translation component 326 can control the horizontal movement of the fixing component 327, specifically controlling the fixing component 327 to move away from or closer to the blister forming line 36. The translation component 326 can use a cylinder to drive the fixing component 327 to move. The punching assembly 325 includes a punching blade adapted to the shape of the blister pack, punching it from one side. The fixing assembly 327 includes a positioning head fixed to the blister pack from the other side. Before punching by the punching assembly 325, the positioning head should fix the corresponding blister pack. The positioning head can be vacuum-adhesive and is also adapted to the outer side of the blister pack. After the aluminum foil moves the blister pack to the corresponding position, the translation assembly 326 drives the positioning head to approach and fix one side of the blister pack. After the blister pack is cut, the positioning head moves away from the blister pack forming line 36, and the blister pack detaches from the aluminum foil. After the punching blade cuts the corresponding blister pack from the aluminum foil, the blister pack is fixed to the positioning head of the fixing assembly 327 and detached from the aluminum foil. At this time, the blister pack on the positioning head can be transferred to a designated position by the transfer assembly. Specifically, the robotic arm of the transfer component also uses vacuum adsorption. It has an adsorption head that is compatible with the blister pack. After the adsorption head of the transfer component adsorbs the blister pack, the positioning head releases the adsorption force on the blister pack, and the blister pack is grasped by the transfer component.

[0082] In a preferred embodiment, the designated position is a horizontally positioned rotary disk that can rotate around its own axis. Several fixtures, such as four, are evenly spaced on the rotary disk. The transfer assembly places the cut blister packs onto one of these fixtures. A pressure testing module is located on one side of the rotary disk. The rotary disk can transfer the blister packs to the pressure testing module for pressure testing. If the test is successful, the rotary disk transfers the qualified blister packs to the blister pack conveyor line 330. The blister pack conveyor line 330 then transfers the qualified blister packs to the assembly line 1 to assemble the reagent cards. The pressure testing module includes a pressure head and a pressure sensor. The pressure head is adapted to the shape of the blister pack, and pressure is applied to detect whether the blister pack meets the pressure requirements.

[0083] See you again Figure 1 Based on the above-mentioned material supply and assembly methods, the material supply efficiency of electrode cards and blister packs is significantly higher than that of assembly line 1. Therefore, the assembly equipment provided by this invention includes two assembly lines 1. The blister pack feeder 3 is connected to the two assembly lines 1 respectively through two blister pack conveyor lines 330. Similarly, the electrode card feeder 2 is also connected to the two assembly lines 1 respectively through two electrode card conveyor lines 24. The upper cover feeder 4 and the lower cover feeder 5 correspond one-to-one with the assembly lines 1, thereby enabling the assembly efficiency to effectively match the material supply efficiency.

[0084] In the preferred embodiment, two assembly lines 1 are arranged in parallel and spaced apart. The blister packer 3 and the electrode card feeder 2 are both located at the beginning of the two assembly lines 1, with the blister packer 3 closer to the beginning of one assembly line 1 and the electrode card feeder 2 closer to the beginning of the other assembly line 1. The aforementioned unloading conveyor line is located at the end of the two assembly lines 1, and the two assembly lines 1 share a single unloading conveyor line. The top cover feeder 4 and the bottom cover feeder 5 are located outside the corresponding assembly lines. This arrangement allows for a very compact overall layout of the assembly equipment, occupying very little space. Furthermore, for this structural form, the blister packer conveyor line 330 includes a main blister packer conveyor line and two branch blister packer conveyor lines. The main blister packer conveyor line is perpendicular to the two branch blister packer conveyor lines and connects to the two branch blister packer conveyor lines and the transfer assembly. Each of the two branch blister packer conveyor lines corresponds one-to-one with one of the two assembly lines 1 and extends along the corresponding assembly line 1. Similarly, the electrode card conveying line 24 also adopts a similar main branch form. There are two electrode card conveying branches, which correspond to the two assembly lines 1. The electrode card conveying main line is used to continuously supply electrode cards to the two electrode card conveying branches.
