Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to a detection card assembly and packaging production line. Background Art

[0002] Antibody-antigen detection, HCG detection, nucleic acid detection, etc. can be carried out using corresponding test strips. Generally, detection cards on the market package the corresponding test strips in a plastic shell, which is assembled by a bottom shell and an upper cover. The detection window and display window of the test strip are exposed for detection and observation and comparison. And the detection card is generally sealed in an aluminum foil bag, and a desiccant is also packaged to play a moisture-proof role. To achieve full automation of assembly and packaging, corresponding automated equipment is required, including the transportation, transfer, positioning, and assembly of the bottom shell, upper cover, and test strip, as well as the transportation, picking, positioning, and packaging of the detection card, desiccant, and packaging bag. Each link and step requires corresponding devices. The bottom shell and the upper cover are both strip-shaped, and there are also front-back and front-back and positive-negative differences during assembly. Sorting and rejection are required before assembly. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a detection card assembly and packaging production line with high automation, high production efficiency, and high yield.

[0004] The present invention is realized by the following technical solutions:

[0005] A detection card assembly and packaging production line includes a bottom shell feeding mechanism, a bottom shell conveying and sorting mechanism, a bottom shell loading mechanism, an assembly station belt, a test strip loading mechanism, an upper cover feeding mechanism, an upper cover conveying and sorting mechanism, an upper cover loading mechanism, a pressing mechanism, and a card discharging mechanism.

[0006] The bottom shell feeding mechanism is arranged on one side of the bottom shell conveying and sorting mechanism and is used to transfer the bottom shells one by one onto the bottom shell conveying and sorting mechanism; the bottom shell conveying and sorting mechanism is used to convey the bottom shells in a row to the bottom shell loading mechanism, and correct and reject the bottom shells that do not meet the requirements in terms of forward-backward or / and front-back directions during the conveying process to facilitate subsequent assembly.

[0007] Both ends of the bottom shell feeding mechanism are respectively connected to the bottom shell conveying and sorting mechanism and the assembly station belt. The assembly station belt is an annular station belt running in the plane direction, and a number of assembly jigs are arranged at intervals on the annular station belt. Driven by the assembly station belt, the assembly jigs sequentially pass through the bottom shell feeding mechanism, the test strip feeding mechanism, the upper cover feeding mechanism, the pressing mechanism and the card discharging mechanism. A number of bottom shell positioning grooves adapted to the bottom shell are arranged on each assembly jig. The bottom shell feeding mechanism is used to transfer and position the bottom shells on the bottom shell conveying and sorting mechanism into the bottom shell positioning grooves, and can pick up one bottom shell at a time. To improve efficiency, all the bottom shell positioning grooves on one assembly jig can also be filled at one time.

[0008] The test strip feeding mechanism is used to transfer the test strips into the bottom shells on the assembly jigs. To improve efficiency, all the bottom shells on one assembly jig can be loaded with test strips at one time.

[0009] The upper cover feeding mechanism, the upper cover conveying and sorting mechanism and the upper cover feeding mechanism are connected in sequence. The upper cover feeding mechanism is arranged on one side of the upper cover conveying and sorting mechanism and is used to pick up the upper covers one by one and transfer them to the upper cover conveying and sorting mechanism. The upper cover conveying and sorting mechanism is used to convey the upper covers in a row to the upper cover feeding mechanism, and correct and remove the upper covers that do not meet the requirements in the forward or / and backward direction during the conveying process to facilitate subsequent assembly. The upper cover feeding mechanism is used to pick up the upper covers on the upper cover conveying and sorting mechanism and place them on the bottom shells on the assembly jigs. All the bottom shells on one assembly jig can be covered with upper covers at one time.

[0010] The pressing mechanism is arranged above the assembly station belt and is used to fasten the upper cover on the bottom shell to form a test card. The test strip is located between the upper cover and the bottom shell, and can act on one assembly jig at a time. The card discharging mechanism is used to pick up the assembled test cards on the assembly station belt and transfer them to the next process.

[0011] Further, the bottom shell feeding mechanism or the upper cover feeding mechanism includes a blanking mechanism, a flat belt, a robotic arm and a robotic gripper. The flat belt is connected to the outlet of the blanking mechanism. The material (bottom shell or upper cover) comes to the flat belt from the outlet of the blanking mechanism. A brush or a brush roller is arranged on the flat belt and is used to sweep the materials on the flat belt into a single layer to avoid overlapping of materials. The robotic arm is arranged beside the flat belt, and the robotic gripper is arranged on the robotic arm. The robotic gripper picks up the materials on the flat belt under the drive of the robotic arm. The robotic arm can move freely in three-dimensional space. The functions of the bottom shell feeding mechanism and the upper cover feeding mechanism are similar and can have the same structure. According to the situation, two or more groups of bottom shell feeding mechanisms or upper cover feeding mechanisms can be set at the same time. The multiple groups of bottom shell feeding mechanisms or upper cover feeding mechanisms pick up the bottom shells or upper covers and transfer them to the same bottom shell conveying and sorting mechanism or upper cover conveying and sorting mechanism.

[0012] The blanking mechanism is a hoist or a vibrating disk conveyor. The hoist is used to lift materials one by one to the discharging height. The vibrating disk conveyor includes a feed bin, a primary vibrating disk, and a secondary vibrating disk. The outlet of the feed bin is docked with the inlet of the primary vibrating disk. The outlet of the primary vibrating disk is docked with the inlet of the secondary vibrating disk. The outlet of the secondary vibrating disk is docked with a flat belt. A number of vibrating troughs adapted to the width of the materials are provided on both the primary vibrating disk and the secondary vibrating disk. After the materials in the feed bin are vibrated by the primary vibrating disk and the secondary vibrating disk, they are arranged in a single-layer queue along the length direction of the materials and conveyed onto the flat belt. Vibrating disk feeding can arrange the materials neatly in the same direction, and the materials are in a single layer. Compared with the messy feeding of the hoist, it is beneficial for visual inspection and mechanical grippers to pick up materials. The time required for visual inspection is greatly shortened, and the feeding speed of the robot at the same time will also be greatly improved.

[0013] The mechanical gripper includes a number of groups of lifting cylinders and suction cups. The number of groups of the lifting cylinders are installed at the end of the same robotic arm. The telescopic end of each group of the lifting cylinders is connected with a group of the suction cups. Each group of lifting cylinders independently drives a group of suction cups to pick up a single material on the flat belt, avoiding interference or impact caused by overlapping materials on the flat belt. Two groups of suction cups picking up materials can improve the feeding efficiency. Each group of suction cups being driven by a separate pneumatic lifting cylinder to move up and down can ensure that the materials to be picked up can still be picked up even when there is interference beside them.

[0014] Further, the bottom shell conveying and sorting mechanism or the upper cover conveying and sorting mechanism includes an outer shell conveyor belt and an outer shell flipping assembly, an outer shell front and back detection assembly, an outer shell blocking assembly, and an outer shell rejection assembly arranged in sequence along the conveying direction of the outer shell conveyor belt. The bottom shell and the upper cover are collectively referred to as the outer shell. A number of outer shell conveying channels are provided on the outer shell conveyor belt. Above each of the outer shell conveying channels, a group of the outer shell flipping assemblies is provided. The outer shell (bottom shell or upper cover) with the front and back sides detected as reversed is placed on the outer shell flipping assembly by the bottom shell feeding mechanism or the upper cover feeding mechanism for flipping to make the front and back sides meet the requirements. The flipped outer shell falls into the outer shell conveying channel; the outer shell front and back detection assembly is used to detect again whether the front and back sides of the outer shell in the outer shell conveying channel meet the requirements, preventing uncorrected outer shells that have been missed or outer shells that have been corrected but not successfully corrected from entering the next process; the outer shell blocking assembly is used to block the subsequent outer shells in the outer shell conveying channel when the outer shell rejection assembly rejects unqualified outer shells, avoiding the influence of the subsequent outer shells on the rejection action; the outer shell rejection assembly is used to reject the unqualified outer shells detected in the outer shell conveying channel.

[0015] Further, the housing flipping assembly includes a first guard plate and a second guard plate which are oppositely arranged. A flipping channel is formed between the first guard plate and the second guard plate. The flipping channel includes a downward-sliding channel located in the upper section and a righting channel located in the lower section. The downward-sliding channel and the righting channel are connected to each other. The width of the entrance of the flipping channel is smaller than the width of the housing.

[0016] At a position on the second guard plate opposite to the first guard plate, there is a second inclined surface that gradually extends downward and toward the second guard plate. At a position on the upper part of the first guard plate opposite to the second inclined surface, there is a first inclined surface that gradually extends downward and toward the second guard plate. The upper edge of the first inclined surface extends to the entrance of the flipping channel. The downward-sliding channel is formed between the first inclined surface and the second inclined surface. The horizontal width of the downward-sliding channel gradually narrows from top to bottom and is smaller than the width of the housing and larger than the thickness of the housing. At a position on the lower part of the first guard plate opposite to the second inclined surface, there is an arc surface that bends toward the first guard plate. The upper edge of the arc surface is connected to the lower edge of the first inclined surface, and the lower edge of the arc surface extends to the bottom of the first guard plate. The righting channel is formed between the arc surface and the second inclined surface. The width of the righting channel gradually widens from top to bottom and is adapted to the width of the housing. The housing changes from an inclined state to a horizontal state in the righting channel. At the top of the second guard plate near the entrance of the flipping channel, there is a placement table. One side of the bottom surface of the housing is horizontally placed on the placement table, and the other side is suspended above the entrance of the flipping channel. The length direction of the housing is parallel to the length direction of the flipping channel, and the suspended side of the housing is larger than the side placed on the placement table, so that the housing turns into the downward-sliding channel due to unstable center of gravity. Under the guiding action of the first inclined surface on the first guard plate, the top surface slides down along the first inclined surface to the righting channel, and then changes from a posture with the top surface obliquely downward to a posture with the top surface facing downward in the righting channel, thus realizing the flipping of the housing.

[0017] Further, the bottom shell conveying and sorting mechanism or the upper cover conveying and sorting mechanism further includes a housing front-back direction detection component. The housing front-back direction detection component is arranged above the housing conveyor belt and at the front end of the housing blocking component, and is used to detect whether the front-back direction of the housing in the housing conveying channel meets the requirements. The housing whose front-back direction does not meet the requirements after detection is removed by the housing blocking component and the housing rejection component to prevent it from entering the next process. That is, the upper covers with the front and back sides not corrected and the upper covers with the front-back direction reversed are all in the list of rejected ones. The bottom shell can also adopt this form to remove all upper covers with the front and back sides reversed or the front-back direction reversed.

[0018] The outer shell rejection component is arranged at the end of the outer shell conveyor belt and includes a plurality of rejection cylinders and rejection plates. The rejection plates are connected to the rejection cylinders, and each outer shell conveying channel corresponds to one rejection plate. When a non-conforming outer shell is detected in the outer shell conveying channel, the corresponding rejection plate is lifted under the drive of the rejection cylinder, so that the outer shell is removed as it moves forward along with the outer shell conveyor belt. After the outer shell is removed, the rejection plate descends, and the outer shell blocking component releases the subsequent outer shells. The rejection plate continues to block the outer shells, and the qualified outer shells blocked are taken by the feeding mechanism.

[0019] The outer shell blocking component can have the same structure as the outer shell rejection component. Above each outer shell conveying channel, a blocking cylinder and a blocking block are correspondingly arranged. The blocking cylinder realizes the blocking function by driving the blocking block to press the outer shell in the corresponding outer shell conveying channel, blocking one outer shell at a time. It can also adopt the structure of one blocking cylinder and one blocking plate. A plurality of blocking blocks corresponding to the outer shell conveying channels are arranged on the blocking plate. The blocking cylinder realizes the blocking function by driving all the blocking blocks on the blocking plate to press the outer shells in all the outer shell conveying channels, blocking all the outer shells at a time.

[0020] Further, the bottom shell feeding mechanism includes a linear movement module, a lifting movement module, a picking fixture, and a buffer station. One end of the linear movement module extends to the bottom shell conveying and sorting mechanism, and the other end extends to the assembly station belt. The lifting movement module is arranged on the linear movement module, the picking fixture is arranged on the lifting movement module, and the buffer station is arranged between the bottom shell conveying and sorting mechanism and the assembly station belt. A plurality of buffer positioning grooves adapted to the bottom shells are arranged on the buffer station. The picking fixture picks the bottom shells on the bottom shell conveying and sorting mechanism to the buffer positioning grooves on the buffer station for positioning under the drive of the linear movement module and the lifting movement module, and picks the bottom shells in the buffer positioning grooves to the bottom shell positioning grooves on the assembly fixture. The picking fixture is a suction cup. In this embodiment, a set of linear movement module and two sets of lifting movement modules are provided. The two sets of lifting movement modules are installed on the same support plate, and the support plate is then installed on the linear movement module. A set of picking fixtures is installed on each set of lifting movement modules, and multiple sets of suction cups are arranged on each set of picking fixtures. A set of picking fixtures picks multiple bottom shells on the bottom shell conveying and sorting mechanism at a time, places the multiple bottom shells on the buffer station for positioning, and the other set of picking fixtures picks multiple bottom shells on the buffer station to the bottom shell positioning grooves on the assembly fixture at a time, and all the bottom shell positioning grooves on the assembly fixture are filled up at once. The two sets of picking fixtures work simultaneously, picking and placing materials at the same time. Since the bottom shell conveying and sorting mechanism is in a moving state, it is difficult to accurately position the bottom shells on it, while the bottom shells on the assembly fixture need to be accurately positioned to facilitate the subsequent insertion of the test strips and the buckling of the upper covers. Therefore, setting a buffer station between the two can play a role of buffering and positioning.

[0021] Further, it also includes a front-back detection mechanism and a front-back steering mechanism for the bottom shell arranged on the assembly station belt. The front-back detection mechanism and the front-back steering mechanism for the bottom shell are sequentially arranged in the middle of the bottom shell feeding mechanism and the test strip feeding mechanism, and are respectively used to detect whether the bottom shell on the assembly jig is reversed front-back and rotate the bottom shell with reversed front-back (the front-back does not meet the requirements) to make the front-back of the bottom shell meet the requirements. At this time, no front-back detection component for the outer shell is arranged on the bottom shell conveying and sorting mechanism. The bottom shell with reversed front-back is detected and removed. These reversed bottom shells enter the assembly station belt and are rotated and corrected by the front-back steering mechanism for the bottom shell. The front-back steering mechanism for the bottom shell can be realized by correspondingly arranging a rotary cylinder or a servo motor above each bottom shell positioning groove on the assembly jig, sucking the bottom shell by a suction cup and then rotating it, and then putting it back into the bottom shell positioning groove after rotating 180 degrees to achieve front-back steering correction.

[0022] The front-back detection mechanism for the bottom shell includes a lifting slide table cylinder, a mounting plate, a proximity switch sensor, a probe and a pressing plate. The mounting plate is mounted on the lifting slide table cylinder. The probe and the pressing plate are arranged on the mounting plate, and the pressing plate is located at the front end of the probe. The pressing plate is used to press the slightly deviated bottom shell on the bottom shell positioning groove in place to facilitate the subsequent detection by the probe. One probe is correspondingly arranged for each bottom shell positioning groove. The probe is pushed up by contacting the correct front end of the bottom shell to detect whether the front-back of the bottom shell meets the requirements. The proximity switch sensor is connected to the probe and is used to sense whether the probe is pushed up. The characteristics of the front-back of the bottom shell are significantly different. When the probe contacts the front end of the bottom shell, if the probe is pushed up, it is the correct front end, and when the proximity switch sensor has a signal input, it indicates that the front-back of the bottom shell is correct, otherwise the front-back is reversed. The front-back detection component for the upper cover can also adopt this structure and form. At the same time, the upper cover can also adopt this form. The front-back and front-back of the upper cover are only corrected and removed on the upper cover conveying and sorting mechanism, and then the front-back detection and removal are carried out on the assembly station belt.

[0023] Furthermore, the front-to-rear steering mechanism of the bottom shell comprises a support frame and at least one group of rotating modules arranged on the support frame, each group of the rotating modules comprises at least one group of linear movement components and at least two groups of lifting and removing rotating components, the lifting and removing rotating components are used to grab and rotate the bottom shell to be rotated in the bottom shell positioning groove, so that the bottom shell rotates a set angle, and all the lifting and removing rotating components on each group of rotating modules are arranged in parallel along the support frame, the linear movement component is connected to the lifting and removing rotating components arranged on the outermost side to drive the lifting and removing rotating components to move linearly and pull a certain distance away from other lifting and removing rotating components, so as to facilitate the lifting and removing rotating components to rotate the removed bottom shell, avoid the lifting and removing rotating components from interfering with each other during rotation due to the length of the bottom shell, and drive the bottom shell to return to its original position after rotation; the total number of all lifting and removing rotating components on all rotating modules is consistent with the number of bottom shell positioning grooves on the assembly jig, and each bottom shell positioning groove corresponds to a group of lifting and removing rotating components;

[0024] The lifting, transferring and rotating assembly comprises a lifting and moving unit, a rotating unit and a transferring unit. The transferring unit is used to suck or clamp the bottom shell. The transferring unit is mounted on the rotating unit. The rotating unit is mounted on the lifting and moving unit. The transferring unit grabs and rotates the bottom shell under the drive of the lifting and moving unit and the rotating unit.

[0025] Furthermore, it also includes a detection card packaging device, which includes a material conveying station belt, a desiccant feeding mechanism, a packaging bag feeding mechanism, a packaging station belt, a pushing mechanism and a sealing mechanism. The material conveying station belt is provided with a plurality of material containing grooves for accommodating detection cards and desiccant at intervals. The card discharging mechanism and the desiccant feeding mechanism transfer the detection card and the desiccant to the material containing grooves respectively. A detection card and a bag of desiccant are placed in a material containing groove. The packaging station belt and the pushing mechanism are respectively arranged on both sides of the material conveying station belt. A plurality of packaging stations are arranged on the packaging station belt. The packaging bag feeding mechanism is used to place the packaging bags one by one on the packaging station. The pushing mechanism is used to push the detection card and the desiccant in the material containing groove into the packaging bag on the packaging station together. The sealing mechanism is arranged on one side of the packaging station belt and at the rear end of the pushing mechanism, and is used to seal the packaging bag loaded with the detection card and the desiccant.

[0026] Further, the desiccant feeding mechanism includes a desiccant vibrating tray, a material sorting and conveying channel, a desiccant conveyor belt, a push rod and a slide plate. The outlet of the desiccant vibrating tray is connected to one end of the material sorting and conveying channel, and the other end of the material sorting and conveying channel is connected to the desiccant conveyor belt. A number of desiccant positioning slots are provided on the desiccant conveyor belt. The desiccants in the desiccant vibrating tray enter the desiccant positioning slots on the desiccant conveyor belt through the material sorting and conveying channel. The push rod and the slide plate are respectively arranged on both sides of the desiccant conveyor belt, and the slide plate is located between the desiccant conveyor belt and the material conveying station belt. A number of slideways are provided on the slide plate. The slideways are arranged obliquely downward. The upper end of the slideway is docked with the desiccant positioning slot, and the lower end of the slideway is docked with the material accommodating slot. The push rod is connected with a push rod driving member, and the push rod driving member drives the push rod to push the desiccants in the desiccant positioning slot into the slideway. The desiccants slide down through the slideway into the material accommodating slot, and finally are pushed into the packaging bag together with the test card. The number of push rods is consistent with the number of slideways. The push rod driving member can be a cylinder. One cylinder is connected to one push rod, or one cylinder is connected to two push rods. The material sorting and conveying channel can be a conveyor belt, and a number of material blocking components are provided on the conveyor belt. The material blocking components sort the desiccants on the conveyor belt into an interval arrangement, and the interval is adapted to the interval of the desiccant positioning slots on the desiccant conveyor belt, which is convenient for putting desiccants one by one onto the desiccant positioning slots.

[0027] Through the setting of corresponding modules, the present invention can realize the full automation of each process from the feeding, sorting, rejection, positioning and transplanting of the bottom shell and the upper cover, to the positioning, sorting, pressing and assembling of the bottom shell, the upper cover and the test strip on the assembling jig, and then to the positioning, pushing and sealing of the test card, the desiccant and the packaging bag at the packaging station. The processes can be smoothly docked with each other, and multiple materials are taken at one time in each process, which improves the feeding speed and the assembling and packaging speed, improves the production efficiency, and positioning devices are provided in multiple processes, so that the materials can be accurately positioned and the finished product rate is high.

Detailed implementation manners

[0050] A detection card assembly and packaging production line, as Figures 1 to 4, including a bottom case feeding mechanism 1, a bottom case conveying and sorting mechanism 2, a bottom case loading mechanism 3, an assembly station belt 4, a test strip loading mechanism 7, an upper cover feeding mechanism 9, an upper cover conveying and sorting mechanism 10, an upper cover loading mechanism 11, a pressing mechanism 12, a card discharging mechanism 14, and a test card packaging device. The test card is formed by buckling a bottom case and an upper cover, with a test strip placed in the middle. When assembling the bottom case and the upper cover, there are distinctions between the front and back as well as the correct and incorrect orientations. During packaging, the test card and a desiccant are jointly sealed in a packaging bag (such as an aluminum foil bag).

[0051] The bottom case feeding mechanism 1 is arranged on one side of the bottom case conveying and sorting mechanism 2 and is used to transfer bottom cases one by one onto the bottom case conveying and sorting mechanism 2. The bottom case conveying and sorting mechanism 2 is used to convey the bottom cases in a row to the bottom case loading mechanism 3 and correct and remove the bottom cases whose front-back or / and correct-incorrect orientations do not meet the requirements during the conveying process to facilitate subsequent assembly.

[0052] Both ends of the bottom case loading mechanism 3 are respectively connected to the bottom case conveying and sorting mechanism 2 and the assembly station belt 4. A number of assembly jigs 41 are arranged at intervals on the assembly station belt 4. Driven by the assembly station belt 4, the assembly jigs 41 sequentially pass through the bottom case loading mechanism 3, the test strip loading mechanism 7, the upper cover loading mechanism 11, the pressing mechanism 12, and the card discharging mechanism 14. A number of bottom case positioning grooves 411 adapted to the bottom cases are provided on each assembly jig 41. The bottom case loading mechanism 3 is used to transfer and position the bottom cases on the bottom case conveying and sorting mechanism 2 into the bottom case positioning grooves 411. One bottom case can be transferred at a time, and for improving efficiency, all the bottom case positioning grooves 411 on one assembly jig 41 can also be filled at once.

[0053] The test strip loading mechanism 7 is used to transfer the test strips into the bottom cases on the assembly jigs 41. For improving efficiency, all the bottom cases on one assembly jig 41 can be loaded with test strips at once. The upper cover feeding mechanism 9, the upper cover conveying and sorting mechanism 10, and the upper cover loading mechanism 11 are connected in sequence. The upper cover feeding mechanism 9 is arranged on one side of the upper cover conveying and sorting mechanism 10 and is used to transfer upper covers one by one onto the upper cover conveying and sorting mechanism 10.

[0054] The upper cover conveying and sorting mechanism 10 is used to convey the upper covers in a row to the upper cover loading mechanism 11 and correct and remove the upper covers whose front-back or / and correct-incorrect orientations do not meet the requirements during the conveying process to facilitate subsequent assembly. The upper cover loading mechanism 11 is used to transfer the upper covers on the upper cover conveying and sorting mechanism 10 onto the bottom cases on the assembly jigs 41. For improving efficiency, all the bottom cases on one assembly jig 41 can be loaded with upper covers at once.

[0055] The pressing mechanism 12 is arranged above the assembly station belt 4, and is used to fasten the upper cover to the bottom shell to form a test card. The test strip is located between the upper cover and the bottom shell. To improve efficiency, it can act on one assembly fixture 41 at a time. The card output mechanism 14 is used to remove the assembled test card on the assembly station belt 4 to the test card packaging device. The test card packaging device is used to package the test card and the desiccant into a packaging bag and seal it.

[0057] The functions of the bottom shell feeding mechanism 1 or the upper cover feeding mechanism 9 are similar, and the same structure and form may be adopted. For example, a robot spider hand or a robot mechanical arm may be used to remove the bottom shell or upper cover in the silo to the bottom shell loading mechanism or the upper cover loading mechanism, and a corresponding visual inspection mechanism may be provided at the same time.

[0058] As one implementation method, in this embodiment, taking the bottom shell feeding mechanism 1 as an example, Figures 5 to 9 , which includes a material discharge mechanism (bottom shell material discharge mechanism), a flat belt (bottom shell flat belt 12), a mechanical arm (bottom shell mechanical arm 13) and a mechanical gripper (bottom shell mechanical gripper 14), the flat belt (bottom shell flat belt 12) is connected to the outlet of the material discharge mechanism (bottom shell material discharge mechanism), and the material (bottom shell 100) comes to the flat belt (bottom shell flat belt 12) from the outlet of the material discharge mechanism (bottom shell material discharge mechanism), and the flat belt (bottom shell flat belt 12) is provided with a brush 16 or a brush 16 roller, which is used to sweep the bottom shell 100 on the flat belt (bottom shell flat belt 12) into a single layer to avoid stacking. Figure 6 , the mechanical arm (bottom shell mechanical arm 13) is arranged beside the flat belt (bottom shell flat belt 12), the mechanical gripper (bottom shell mechanical gripper 14) is arranged on the mechanical arm (bottom shell mechanical arm 13), and the mechanical gripper (bottom shell mechanical gripper 14) removes the material on the flat belt (bottom shell flat belt 12) under the drive of the mechanical arm (bottom shell mechanical arm 13). The mechanical arm (bottom shell mechanical arm 13) can move freely in three-dimensional space. According to the situation, two or more groups of bottom shell feeding mechanisms 1 or upper cover feeding mechanisms 9 can be set at the same time. In order to increase the feeding speed, two groups of bottom shell feeding mechanisms 1 and two groups of upper cover feeding mechanisms 9 are set in this embodiment, and the bottom shell and the upper cover are respectively moved to the same bottom shell conveying and sorting mechanism 2 and upper cover conveying and sorting mechanism 10. A visual inspection mechanism is arranged above the flat belt (bottom shell flat belt 12) for detecting the condition of the material. For the bottom shell feeding mechanism 1, it corresponds to the bottom shell visual inspection mechanism 15, which can detect the front and back conditions of the bottom shell. The mechanical gripper (bottom shell mechanical gripper 14) selects the corresponding operation accordingly, and the same applies to the upper cover feeding mechanism 9.

[0059] The unloading mechanism (bottom shell unloading mechanism) can be the hoist 11 in the figure, or can be Figure 9The shown vibrating tray conveyor, the elevator 11 is used to lift materials one by one to the discharging height. The vibrating tray conveyor includes a material bin 17, a first-stage vibrating tray 18 and a second-stage vibrating tray 19. The outlet of the material bin 17 is docked with the inlet of the first-stage vibrating tray 18, the outlet of the first-stage vibrating tray 18 is docked with the inlet of the second-stage vibrating tray 19, and the outlet of the second-stage vibrating tray 19 is docked with a flat belt (the bottom shell flat belt 12). A number of vibrating troughs 191 adapted to the width of the materials are provided on both the first-stage vibrating tray 18 and the second-stage vibrating tray 19. After the materials in the material bin 17 are vibrated by the first-stage vibrating tray 18 and the second-stage vibrating tray 19, they are arranged in a single-layer queue along the length direction of the materials and conveyed onto the flat belt (the bottom shell flat belt 12). Vibrating tray feeding can arrange the materials neatly in the same direction, and the materials are in a single layer. Compared with the messy feeding of the elevator 11, it is beneficial for visual inspection and the mechanical gripper (the bottom shell mechanical gripper 14) to pick up materials. The time required for visual inspection is greatly shortened, and the feeding speed of the robot at the same time will also be greatly improved. When the feeding mechanism (the bottom shell feeding mechanism) is a vibrating tray conveyor, the brush 16 or the brush 16 roller may not be installed on the flat belt (the bottom shell flat belt 12), or the brush 16 or the brush 16 roller may be installed at the outlet of the material bin 17.

[0060] In this embodiment, as Figure 7 , Figure 8 , the mechanical gripper (the bottom shell mechanical gripper 14) includes a number of groups of lifting cylinders (the bottom shell lifting cylinders 141) and suction cups (the bottom shell suction cups 142). A number of groups of the lifting cylinders (the bottom shell lifting cylinders 141) are installed at the end of the same robotic arm (the bottom shell robotic arm 13). The telescopic end of each group of the lifting cylinders (the bottom shell lifting cylinders 141) is connected with a group of the suction cups (the bottom shell suction cups 142). Each group of lifting cylinders (the bottom shell lifting cylinders 141) individually drives a group of suction cups (the bottom shell suction cups 142) to pick up a single material on the flat belt (the bottom shell flat belt 12), avoiding interference or impact caused by material stacking on the flat belt (the bottom shell flat belt 12). Two groups of suction cups (the bottom shell suction cups 142) picking up materials can improve the feeding efficiency. Each group of suction cups (the bottom shell suction cups 142) being driven by a separate pneumatic lifting cylinder to move up and down can ensure that the materials to be grabbed can still be grabbed even when there is interference beside the materials to be grabbed. The upper cover feeding mechanism 9 is the same.

[0061] 2. The bottom shell conveying and sorting mechanism 2 and the upper cover conveying and sorting mechanism 10

[0062] The functions of the bottom shell conveying and sorting mechanism 2 and the upper cover conveying and sorting mechanism 10 are similar, and the same structure can also be adopted. For the convenience of description, the bottom shell and the upper cover are collectively referred to as the outer shell. In this embodiment, taking the bottom shell conveying and sorting mechanism 2 as an example, as Figures 10 to 14, which includes a housing conveyor belt (bottom housing conveyor belt 21) and a housing flipping assembly (bottom housing flipping assembly 22), a housing front and back detection assembly (bottom housing front and back detection assembly 23), a housing blocking assembly (bottom housing blocking assembly 24), and a housing rejection assembly (bottom housing rejection assembly 25) arranged in sequence along the conveying direction of the housing conveyor belt (bottom housing conveyor belt 21). The upper cover conveying and sorting mechanism 10 is similar.

[0063] A number of housing conveying channels (bottom housing conveying channels 211) are provided on the housing conveyor belt (bottom housing conveyor belt 21). Above each housing conveying channel (bottom housing conveying channel 211), a set of the housing flipping assembly (bottom housing flipping assembly 22) is provided. The housing (bottom housing 100) detected with the front and back sides reversed is placed on the housing flipping assembly (bottom housing flipping assembly 22) by the bottom housing feeding mechanism 1 or the upper cover feeding mechanism 9 for flipping to make the front and back sides meet the requirements. The flipped bottom housing 100 falls into the housing conveying channel (bottom housing conveying channel 211).

[0064] To further ensure that the front and back sides of all housings meet the requirements, a housing front and back detection assembly (bottom housing front and back detection assembly 23) is also provided at the rear end of the housing flipping assembly (bottom housing flipping assembly 22) to re-detect whether the front and back sides of the bottom housing 100 in the housing conveying channel (bottom housing conveying channel 211) meet the requirements, so as to prevent the bottom housing 100 that has been missed without correction or has been corrected but not successfully corrected from entering the next process. The housing blocking assembly (bottom housing blocking assembly 24) is used to block the subsequent bottom housing 100 in the housing conveying channel (bottom housing conveying channel 211) when the housing rejection assembly (bottom housing rejection assembly 25) rejects the non-conforming housing, to avoid the influence of the subsequent bottom housing 100 on the rejection operation; the housing rejection assembly (bottom housing rejection assembly 25) is used to reject the non-conforming bottom housing 100 detected in the housing conveying channel (bottom housing conveying channel 211).

[0065] The function of the housing flipping assembly (bottom housing flipping assembly 22) is to flip the bottom housing 100 by 180 degrees in the vertical plane to reverse the front and back sides. As one of the implementation manners, such as Figure 12 , Figure 13, the housing flipping assembly (bottom housing flipping assembly 22) includes a mounting frame 221 and a first guard plate 222 and a second guard plate 223 oppositely arranged on the mounting frame 221. A flipping channel 224 is formed between the first guard plate 222 and the second guard plate 223. The flipping channel 224 includes a downward-sliding channel 2241 in the upper section and a righting channel 2242 in the lower section. The downward-sliding channel 2241 and the righting channel 2242 are connected to each other. The width of the entrance of the flipping channel 224 is smaller than the width of the housing (bottom housing 100). At a position on the second guard plate 223 opposite to the first guard plate 222, there is a second inclined surface 2232 that gradually extends downward and toward the second guard plate 223 side. At a position on the upper part of the first guard plate 222 opposite to the second inclined surface 2232, there is a first inclined surface 2221 that gradually extends downward and toward the second guard plate 223 side. The upper edge of the first inclined surface 2221 extends to the entrance of the flipping channel 224. The downward-sliding channel 2241 is formed between the first inclined surface 2221 and the second inclined surface 2232. The horizontal width of the downward-sliding channel 2241 gradually becomes narrower from top to bottom and is smaller than the width of the housing (bottom housing 100) and larger than the thickness of the housing (bottom housing 100). At a position on the lower part of the first guard plate 222 opposite to the second inclined surface 2232, there is an arc surface 2222 that bends toward the first guard plate 222 side. The upper edge of the arc surface 2222 is connected to the lower edge of the first inclined surface 2221, and the lower edge of the arc surface 2222 extends to the bottom of the first guard plate 222. The righting channel 2242 is formed between the arc surface 2222 and the second inclined surface 2232. The width of the righting channel 2242 gradually becomes wider from top to bottom and is adapted to the width of the housing (bottom housing 100). The housing (bottom housing 100) changes from an inclined state to a horizontal state in the righting channel 2242; at the top of the second guard plate 223 near the entrance of the flipping channel 224, there is a placement table 2231. One side of the bottom surface of the housing (bottom housing 100) is horizontally placed on the placement table 2231, and the other side is suspended above the entrance of the flipping channel 224. The length direction of the housing (bottom housing 100) is parallel to the length direction of the flipping channel 224, and the suspended side of the housing (bottom housing 100) is larger than the side placed on the placement table 2231, so that the housing (bottom housing 100) flips into the downward-sliding channel 2241 due to unstable center of gravity. The top surface slides along the first inclined surface 2221 to the righting channel 2242 under the guiding action of the first inclined surface 2221 on the first guard plate 222, and then changes from a posture with the top surface obliquely downward to a posture with the top surface facing downward in the righting channel 2242, thus realizing the flipping of the housing (bottom housing 100). A manipulator places a small half of the housing (bottom housing 100) on the placement table 2231, and the other large half is suspended, and then the housing (bottom housing 100) automatically flips into the flipping channel 224.

[0066] The normal front and back outer shells (bottom shells) are directly placed into the outer shell conveying channel (bottom shell conveying channel 211) by the manipulator. In this embodiment, four outer shell conveying channels (bottom shell conveying channels 211) are provided on the outer shell conveyor belt (bottom shell conveyor belt 21), and each manipulator is responsible for two outer shell conveying channels (bottom shell conveying channels 211) to grab two outer shells (bottom shells). Compared with the flipping forms of structures such as rotary cylinders or motors, the structure is simple, more economical and practical, and the overall structure is small and suitable for being arranged on the outer shell conveyor belt (bottom shell conveyor belt 21). The mounting frame 221 is fixed on both sides of the outer shell conveyor belt (bottom shell conveyor belt 21).

[0067] In this embodiment, the upper cover conveying and sorting mechanism 10 further includes an outer shell front-back detection component (upper cover front-back detection component). The outer shell front-back detection component (upper cover front-back detection component) is arranged above the outer shell conveyor belt (upper cover conveyor belt) and at the front end of the outer shell blocking component (upper cover blocking component), and is used to detect whether the front and back directions of the outer shell in the outer shell conveying channel (upper cover conveying channel) meet the requirements. The outer shells that do not meet the requirements after detection are removed through the outer shell blocking component (upper cover blocking component) and the outer shell removal component (upper cover removal component) to prevent them from entering the next process. That is, the upper covers with the front and back sides reversed and not corrected and the upper covers with the front and back directions reversed are both in the list of removed ones. The outer shell front-back detection component (upper cover front-back detection component) can adopt a visual detection structure.

[0068] An outer shell front-back detection component (bottom shell front-back detection component) can also be provided on the bottom shell conveying and sorting mechanism 2 to remove the bottom shells that do not meet the requirements in the front and back directions. However, in this embodiment, the outer shell front-back detection component (bottom shell front-back detection component) is not provided on the bottom shell conveying and sorting mechanism 2, so that all the bottom shells with the correct front and back sides enter the assembly station belt 4. Then, a bottom shell front-back detection mechanism 5 and a bottom shell front-back turning mechanism 6 are provided on the assembly station belt 4 to detect and rotate the bottom shells with incorrect front and back directions. For details, see the following text.

[0069] The outer shell removal component (bottom shell removal component 25) is arranged at the end of the outer shell conveyor belt (bottom shell conveyor belt 21), such as Figure 14 , which includes a plurality of removal cylinders 251 and a removal plate 252. The removal plate 252 is connected to the removal cylinder 251. One removal plate 252 corresponds to each outer shell conveying channel (bottom shell conveying channel 211). When it is detected that there is a non-compliant outer shell in the outer shell conveying channel (bottom shell conveying channel 211), the corresponding removal plate 252 is lifted under the drive of the removal cylinder 251 to remove the outer shell as the outer shell conveyor belt (bottom shell conveyor belt 21) moves forward. After the outer shell is removed, the removal plate 252 descends, and the outer shell blocking component (bottom shell blocking component 24) releases the subsequent outer shells. The removal plate 252 continues to block the outer shells, and the blocked qualified outer shells are taken by the feeding mechanism.

[0070] The housing blocking assembly (bottom housing blocking assembly 24) can have the same structure as the housing removing assembly (bottom housing removing assembly 25). Above each housing conveying channel (bottom housing conveying channel 211), a blocking cylinder and a blocking block are correspondingly arranged. The blocking cylinder drives the blocking block to press the housing in the corresponding housing conveying channel (bottom housing conveying channel 211) to achieve the blocking function, blocking one housing at a time. It is also possible to adopt the structure of one blocking cylinder and one blocking plate. Several blocking blocks corresponding to the housing conveying channel (bottom housing conveying channel 211) are arranged on the blocking plate. The blocking cylinder drives all the blocking blocks on the blocking plate to press the housing in all the housing conveying channels (bottom housing conveying channel 211) to achieve the blocking function, blocking all the housings at a time.

[0071] 3. Bottom housing loading mechanism 3 and upper cover loading mechanism 11

[0072] The functions of the bottom housing loading mechanism 3 and the upper cover loading mechanism 11 are similar and can adopt the same structure. Taking the bottom housing loading mechanism 3 as an example, as Figure 15 , it includes a linear movement module 31, a lifting movement module 33, a picking fixture 34, and a buffer station 35. One end of the linear movement module 31 extends to the bottom housing conveying and sorting mechanism 2, and the other end extends to the assembly station belt 4. The lifting movement module 33 is arranged on the linear movement module 31. The picking fixture 34 is arranged on the lifting movement module 33. The buffer station 35 is arranged between the bottom housing conveying and sorting mechanism 2 and the assembly station belt 4. Several buffer positioning grooves 351 adapted to the bottom housing are arranged on the buffer station 35. The picking fixture 34 picks the bottom housing on the bottom housing conveying and sorting mechanism 2 to the buffer positioning grooves 351 on the buffer station 35 for positioning under the drive of the linear movement module 31 and the lifting movement module 33, and picks the bottom housing in the buffer positioning grooves 351 to the bottom housing positioning grooves 411 on the assembly fixture 41.

[0073] In this embodiment, the picking fixture 34 is a suction cup. One set of linear motion modules 31 and two sets of lifting motion modules 33 are provided. The two sets of lifting motion modules 33 are installed on the same support plate 32, and the support plate 32 is further installed on the linear motion module 31. One set of picking fixtures 34 is installed on each set of lifting motion modules 33, and multiple sets of suction cups are provided on each set of picking fixtures 34. One set of picking fixtures 34 picks up multiple bottom shells on the bottom shell conveying and sorting mechanism 2 at one time, places the multiple bottom shells on the buffer station 35 for positioning, and the other set of picking fixtures 34 picks up multiple bottom shells on the buffer station 35 to the bottom shell positioning grooves 411 on the assembly jig 41 at one time, and all the multiple bottom shell positioning grooves 411 on the assembly jig 41 are filled up at one time. The two sets of picking fixtures 34 work simultaneously, picking and placing materials at the same time. The two sets of picking fixtures 34 can also adopt independent drive structures. Since the bottom shell conveying and sorting mechanism 2 is in a moving state, it is difficult to accurately position the bottom shells on it, while the bottom shells on the assembly jig 41 need to be accurately positioned to facilitate the subsequent insertion of the test strips and the fastening of the upper covers. Therefore, a buffer station 35 is provided between the two to play a role in buffering and positioning.

[0074] 4. Assembly station belt 4

[0075] The assembly station belt 4 in this embodiment is an annular station belt. A bottom shell front-back detection mechanism 5 and a bottom shell front-back turning mechanism 6 are further provided above the assembly station belt 4. The bottom shell front-back detection mechanism 5 and the bottom shell front-back turning mechanism 6 are sequentially arranged between the bottom shell feeding mechanism 3 and the test strip feeding mechanism 7, and are respectively used to detect whether the bottom shells on the assembly jig 41 are front-back reversed and rotate the bottom shells with front-back reversal (the front-back direction does not meet the requirements) to make the front-back direction of the bottom shells meet the requirements. At this time, no shell front-back detection component (upper cover front-back detection component) is provided on the bottom shell conveying and sorting mechanism 2 to detect and remove the bottom shells with front-back reversal. These reversed bottom shells enter the assembly station belt 4 and are rotated and corrected by the bottom shell front-back turning mechanism 6.

[0076] The bottom shell front-back detection mechanism 5 can adopt a visual detection form. In this embodiment, such as Figure 16 、 Figure 17The bottom shell front-to-back detection mechanism 5 includes a lifting slide cylinder 51, a mounting plate 52, a proximity switch sensor 53, a probe 54 and a pressing plate 55. The mounting plate 52 is mounted on the lifting slide cylinder 51. The probe 54 and the pressing plate 55 are arranged on the mounting plate 52, and the pressing plate 55 is located at the front end of the probe 54. The pressing plate 55 is used to press the slightly deviated bottom shell on the bottom shell positioning groove 411 into place, so as to facilitate the subsequent detection of the probe 54. Each bottom shell positioning groove 411 is correspondingly provided with a probe 54. The probe 54 is lifted up by contacting the correct front end of the bottom shell to detect whether the front-to-back direction of the bottom shell meets the requirements. The proximity switch sensor 53 is connected to the probe 54 to sense whether the probe 54 is lifted up. The front-to-back characteristics of the bottom shell are obviously different. The probe 54 contacts the front end of the bottom shell. If the probe 54 is lifted up, it is the correct front end. The proximity switch sensor 53 has a signal input, indicating that the front-to-back direction of the bottom shell is correct, otherwise the front-to-back direction is reversed.

[0077] The bottom shell forward and backward steering mechanism 6 can be provided with a rotating cylinder or a servo motor corresponding to the top of each bottom shell positioning groove 411 on the assembly jig 41, and the bottom shell is sucked by a suction cup and rotated, and then put back into the bottom shell positioning groove after rotating 180 degrees to achieve forward and backward steering correction. In order to reasonably arrange and solve the problem of mutual interference when adjacent long bottom shells rotate, as one of the implementation methods, Figure 18 , Figure 19 The bottom shell front-back steering mechanism 6 includes a support frame 61 and at least one set of rotating modules arranged on the support frame 61, each set of rotating modules includes at least one set of linear moving components 62 and at least two sets of lifting and removing rotating components 63, the lifting and removing rotating components 63 are used to grab and rotate the bottom shell 100 to be rotated in the bottom shell positioning groove 411, so that the bottom shell rotates by a set angle, all the lifting and removing rotating components 63 on each set of rotating modules are arranged in parallel along the support frame 61, the linear moving components 62 and the lifting and removing rotating components arranged on the outermost side are connected to each other. The rotating assembly 63 is connected to drive the lifting and removing rotating assembly 63 to move linearly and to pull a certain distance from other lifting and removing rotating assemblies 63, so as to facilitate the lifting and removing rotating assembly 63 to rotate the removed bottom shell 100, avoid the lifting and removing rotating assembly 63 from interfering with each other when the bottom shell is too long, and drive the bottom shell to return after rotation; the total number of all lifting and removing rotating assemblies 63 on all rotating modules is consistent with the number of bottom shell positioning grooves 411 on the assembly fixture 41, and each bottom shell positioning groove 411 corresponds to a group of lifting and removing rotating assemblies 63. The linear moving assembly 62 can be an existing structure or form, and can also be as Figure 18 , Figure 19 The structures shown include the opening cylinder 621 and the opening slide rail 622.

[0078] The lifting, picking and rotating assembly 63 includes a lifting and moving unit 631, a rotating unit 632 and a picking unit 633. The picking unit 633 is used to suck or clamp the bottom shell. The picking unit 633 is installed on the rotating unit 632, and the rotating unit 632 is installed on the lifting and moving unit 631. The picking unit 633 grabs and rotates the bottom shell under the drive of the lifting and moving unit 631 and the rotating unit 632. As Figure 18 , the lifting and moving unit 631 can be a slide cylinder, the rotating unit 632 can be a rotating cylinder, and the picking unit 633 can be a suction cup or a cylinder gripper.

[0079] In this embodiment, two sets of rotating modules are provided, which are respectively arranged on the front and rear sides (along the running direction of the assembly station belt 4) of the support frame 61. Each set of rotating modules includes a set of linear moving components 62 and two sets of lifting, picking and rotating assemblies 63. There are a total of four sets of lifting, picking and rotating assemblies 63, and the four sets of lifting, picking and rotating assemblies 63 are arranged in a staggered manner to correspond to the four bottom shell positioning grooves 411 on the assembly jig respectively. When the length of the bottom shell is too long and two adjacent lifting, picking and rotating assemblies 63 need to work simultaneously, the linear moving component 62 works to separate the two sets of lifting, picking and rotating assemblies 63, and then resets after rotation to put the rotated bottom shell back, meeting the requirements of assembling detection cards of different specifications.

[0080] The front-back detection component of the upper cover can also adopt the structure and form of the above-mentioned front-back detection mechanism 5 of the bottom shell. At the same time, the upper cover can also adopt the forms of the above-mentioned bottom shell conveying and sorting mechanism 2 and bottom shell front-back turning mechanism 6. The upper cover conveying and sorting mechanism 10 only corrects and removes the front and back sides of the upper cover, and then conducts front-back detection and removal on the assembly station belt 4.

[0081] A strip loading detection mechanism 8 is also provided between the test strip feeding mechanism 7 and the upper cover feeding mechanism 9 to detect the loading condition of the test strip (whether the position is off-track and whether there is missing loading).

[0082] As Figure 20 , the pressing mechanism 12 in this embodiment adopts the form of a pressing cylinder 121, a pressing plate 122 and pressing blocks 123. A number of pressing blocks 123 are installed at the bottom of the pressing plate 122, and each bottom shell positioning groove 411 on the assembly jig 41 corresponds to a pressing block 123. The pressing cylinder 121 drives the pressing plate 122 and the pressing blocks 123 to act on the upper cover for pressing.

[0083] A pressing detection mechanism 13 is also provided between the pressing mechanism 12 and the card discharging mechanism 14 to detect whether there are situations such as off-track pressing position and non-alignment in the front-back direction.

[0084] The test strip loading mechanism 7 and the card discharging mechanism 14 can both adopt existing technologies, such as the form of a robotic manipulator, to place the neatly arranged test strips into the bottom case and transfer the test cards on the assembly jig 41 to the test card packaging device. Appropriate linear modules, lifting modules, and suction cup grippers can be set up. The slitting, arranging, and positioning of the test strips can be achieved by the test strip slitting mechanism 21 and the test strip feeding mechanism 22 as shown in the figure, or existing structures and forms can also be adopted.

[0085] 5. Test Card Packaging Device

[0086] Such as Figures 1 to 4 , the test card packaging device includes a material conveying station belt 15, a desiccant feeding mechanism 16, a packaging bag feeding mechanism 17, a packaging station belt 18, a pushing mechanism 19, and a sealing mechanism 20. A number of material accommodating grooves 151 for accommodating test cards and desiccants are arranged at intervals on the material conveying station belt 15. The card discharging mechanism 14 and the desiccant feeding mechanism 16 respectively transfer the test cards and desiccants into the material accommodating grooves 151. One test card and one pack of desiccant are placed in one material accommodating groove 151. The packaging station belt 18 and the pushing mechanism 19 are respectively arranged on both sides of the material conveying station belt 15. A number of packaging stations are arranged on the packaging station belt 18. The packaging bag feeding mechanism 17 is used to place the packaging bags one by one on the packaging stations. The pushing mechanism 19 is used to push the test cards and desiccants in the material accommodating grooves 151 into the packaging bags on the packaging stations together. The sealing mechanism 20 is arranged on one side of the packaging station belt 18 and behind the pushing mechanism 19, and is used to seal the packaging bags filled with test cards and desiccants.

[0087] In this embodiment, such as Figure 21, the desiccant feeding mechanism 16 includes a desiccant vibrating disk 161, a material sorting and conveying channel 162, a desiccant conveyor belt 163, a push rod 165 and a slide plate 166. The outlet of the desiccant vibrating disk 161 is connected to one end of the material sorting and conveying channel 162, and the other end of the material sorting and conveying channel 162 is connected to the desiccant conveyor belt 163. A number of desiccant positioning slots 1631 are provided on the desiccant conveyor belt 163. The desiccants in the desiccant vibrating disk 161 enter the desiccant positioning slots 1631 on the desiccant conveyor belt 163 through the material sorting and conveying channel 162. The push rod 165 and the slide plate 166 are respectively arranged on both sides of the desiccant conveyor belt 163, and the slide plate 166 is located between the desiccant conveyor belt 163 and the material conveying station belt 15. A number of slideways 1661 are provided on the slide plate 166. The slideways 1661 are arranged obliquely downward. The upper end of the slideway 1661 is docked with the desiccant positioning slot 1631, and the lower end of the slideway 1661 is docked with the material accommodating slot 151. The push rod 165 is connected with a push rod driving member. In this embodiment, the push rod driving member is a pushing cylinder 164. The push rod driving member drives the push rod 165 to push the desiccant in the desiccant positioning slot 1631 into the slideway 1661. The desiccant slides down through the slideway 1661 into the material accommodating slot 151, and finally is pushed into the packaging bag together with the detection card. The number of the push rods 165 is consistent with the number of the slideways 1661. The push rod driving member can be a cylinder. One cylinder is connected to one push rod 165, or one cylinder is connected to two push rods 165. The material sorting and conveying channel 162 can be a conveyor belt. A number of material blocking components are provided on the conveyor belt. The material blocking components sort the desiccants on the conveyor belt into spaced arrangements, and the spacing is adapted to the spacing of the desiccant positioning slots 1631 on the desiccant conveyor belt 163, which is convenient for putting desiccants one by one onto the desiccant positioning slots 1631.

[0088] The packaging bag feeding mechanism 17, the pushing mechanism 19 and the sealing mechanism 20 can all adopt existing structures and forms, or the forms as shown in the figure in this embodiment. The packaging bag feeding mechanism 17 alternately sucks and releases the packaging bags through a suction cup, and sucks the packaging bags one by one from the bin 17 to the packaging station; the pushing mechanism 19 pushes the push plate through a servo motor.
