The whole process of loading the reagent plate of the exemplary embodiment of the present invention to the desiccant and then filling the reagent plate into the packaging bag and vacuum-pumping and heat-sealing will be described in detail.

After the machine is started, referring to fig. 8 and 1, the stepping mechanism 51 in the pushing and bagging unit 5 starts to operate, and the pushing stepping motor 511 in the pushing and bagging unit 5 is started to drive the pushing sliding table 512 to rotate, so that the pushing station 513 is driven to move to the feeding end, namely the side of the reagent plate feeding unit 1.

With reference to fig. 3, 8 and 1, the receiving cylinder 121 is then activated to drive the receiving tray 122 to move upwards, and the receiving tray 122 passes through the circular hole in the pushing station 513 to a position below the reagent plate bin 111, and leaves a gap of the reagent plate 100. Subsequently, the bin cylinder 112 is started to drive the bin claw 113 to move outwards, and at the moment, the reagent plate 100 falls downwards under the influence of gravity and is supported by the receiving tray 122, wherein the shape of the reagent plate bin 111 is consistent with the outer edge of the reagent plate 100, and the direction and the shape of the falling process are ensured to be in a controllable range.

The bin cylinders 112 are then started to drive the bin claws 113 to move inwards to clamp the reagent plates 100, so that each receiving tray 122 is guaranteed to only hold one reagent plate 100, then the receiving cylinders 121 are started to drive the receiving trays 122 to move downwards, in the moving process, the reagent plates 100 are contacted with the edge chamfer of the pushing station 513, and the receiving trays 122 pass through round holes in the pushing station 513. At this point the reagent plate is affected by gravity and the edge chamfer of the pushing station, steadily falling to the pushing station 513. So far, the reagent plate feeding process is completed.

Referring next to fig. 4 and 5, the desiccant driving module 211 is started to drive the auxiliary rotating wheel 212 to rotate, drive the desiccant 200 to leave from the desiccant roll to form a strip shape, and move the desiccant to the cutting module 213, and then the cutting module 213 is started, wherein the cutting module 213 comprises a sensor, and after the sensor automatically recognizes the cut mark on the package bag 200, the blade in the cutting module 213 cuts the desiccant 200 from the strip shape into small bags.

Referring next to fig. 4 and 5, the desiccant 200 falls into the desiccant dispensing mechanism 22. The separating stepper motor 223 is started to drive the linear sliding table 222 to move, the movable guide seat 221 is driven to move left and right, the movement of the separating stepper motor is precisely controlled by the PLC in the electric cabinet 01, the movable guide seat 221 is positioned at the rightmost side when the first knife is cut under the cutting module 213, the falling drying agent 200 in the drying agent cutting mechanism 21 falls into the leftmost fixed guide pipe 224 on the movable guide seat 221, then the separating stepper motor 223 is started to drive the linear sliding table 222 to move, the movable guide seat 221 is driven to move leftwards, and at the moment, the falling drying agent 200 of the drying agent cutting mechanism 21 falls into the leftmost second fixed guide pipe 224 on the movable guide seat 221. Similarly, in each round of packaging work, the desiccant delivery unit 2 cuts four pouches of desiccant 200 and drops into four fixed ducts 224, respectively.

With reference to fig. 8, 4 and 1, the stepping mechanism 51 in the pushing and bagging unit 5 starts to operate, the pushing stepping motor 511 is started to drive the pushing sliding table 512 to move, the pushing station 513 is driven to move leftwards to be right below the drying agent feeding unit 2, and with reference to fig. 4 and 5, the baffle cylinder 225 is started, and the drying agent 200 falls from the fixed conduit 224 to be located above the reagent plate 200 in the pushing station 513. The dryer feeding process has been completed so far.

Referring next to fig. 6 and 2, the bag taking cylinder 31 in the bag feeding unit 3 is started to drive the sucker fixing frame 32 to move upwards, and drive the single sucker taking module 33 to move upwards to the position below the bag storage bin 34, at this time, the sucker in the bag taking sucker module 33 is closely attached to the lowest bag 300 in the bag storage bin 34. Then the vacuum generator in the bag-taking sucker module is started, so that negative pressure is generated in the sucker in the bag-taking sucker module 33, and the lower surface of the packaging bag 300 is tightly sucked by the sucker in the bag-taking sucker module 33 under the action of pressure difference. The bag take cylinder 31 then repeats the small up and down motions to disengage the bag from the other bags 200 in the bag magazine 34.

Then the bag taking cylinder 31 is started to drive the sucker fixing frame 32 to move downwards, and the bag taking sucker module 33 is driven to suck the packaging bag 300 to move downwards to the bagging station 35. At this time, the vacuum generator in the bag taking suction disc module 33 continuously works, so that the packaging bag 300 is ensured to be horizontally placed at the bagging station 35, and the bag opening of the packaging bag 300 faces the pushing bagging unit 5.

Referring to fig. 7, 6 and 2, the blocking cylinder 46 of the bag opening and conveying unit 4 is started to drive the baffle 47 to retract upwards, and then the pneumatic sliding table 41 is started to drive the conveying table 42 to move rightwards to the position right above the bagging station 35. Then the grabbing cylinder 43 is started to drive the bag opening sucker fixing frame 44 to move downwards, and drive the bag opening sucker module 45 to move downwards until the sucker in the bag opening sucker module 45 clings to the upper surface of the packaging bag 300 on the bagging station 35. Then the vacuum generator in the bag opening suction cup module 45 is started, so that negative pressure is generated in the suction cup of the bag opening suction cup module 45, and the upper surface of the packaging bag 300 is tightly sucked by the suction cup in the bag opening suction cup module 45 under the action of pressure difference. Subsequently, the grabbing cylinder 43 is started to drive the bag opening sucker fixing frame 44 to move upwards, and drive the bag opening sucker module 45 to move upwards. At this time, the upper and lower surfaces of the packing bag 300 are opened by the bag-taking suction cup module 33 and the bag-opening suction cup module 45, and are changed from the approximately planar shape to the open three-dimensional shape.

With reference to fig. 8, 6 and 2, the stepping mechanism 51 in the pushing and bagging unit 5 starts to operate, and the pushing stepping motor 511 is started to drive the pushing sliding table 512 to move, so that the pushing station 513 is driven to move leftwards to the right (right in the drawing) of the bagging station 35. Wherein the position of the opening-supporting claw 524 of the bagging mechanism 52 in the pushing and bagging unit 5 reaches the opening of the bag 300 to be opened. The bagging mechanism 52 located at the pushing and bagging unit 5 starts bagging, wherein the bagging cylinder 521 is started to drive the push rod connecting frame 522 to move to drive the push plate 523 to move, at this time, the reagent plate 100 and the drying agent 200 are located in the pushing station 513, the push plate 523 is located at the rear (right side in the drawing) of the pushing station, and the reagent plate 100 and the drying agent are pushed to leave the pushing station 513 together when the push plate 523 moves to enter the bagging station 35.

It should be noted that, referring to fig. 8, 6, and 2, during the process of pushing the reagent plate 100 and the desiccant 200 by the pushing plate 523, the edge of the reagent plate 100 touches the inside of the opening claw 524 of the bagging mechanism 52. The outer sides of the propping claws 524 are fixed at the outer side edge of the pushing station 513 by bearings, and the propping claws 524 generate rotary motion under the force conduction action of the reagent plate 100, and the claw parts are propped up along with the displacement of the reagent plate. Since the opening holding claw 524 is in the package 300 at this time under a series of actions of the pushing stepper motor 511 before, the opening holding claw 524 contacts the inner edge of the package 300 and holds it open during the opening process, the shape of the opened package 300 is changed from an originally irregular opening to an opening having the same shape as the reagent plate 100, and the opening is slightly larger than the reagent plate 100 in size. At the same time, the reagent sheet 100 and the desiccant 200 enter the inside of the package 300 in response to the opening of the package. The design and the application of the structure ensure the smooth bagging of the reagent plate 100, and avoid the difficult problem that the reagent plate 100 is large and is difficult to automatically bag because the bag opening is too small. Then, as the reagent sheet 100 is completely inserted into the packing bag 300, the force applied to the edge of the mouth supporting claws 524 by the reagent sheet 100 is completely removed, the springs 525 on the mouth supporting claws 524 are deformed by the force previously generated by the mouth supporting claws 524, and after the force is removed, the elastic force generated by the springs 525 makes the mouth supporting claws restore to the original shape. The design and application ensures that the jaws of the jaws are retracted, so that the jaws 524 can smoothly extend into the package 300 during the next packaging process. Subsequently, the bag-taking suction cup module 33 in the bag-feeding unit 3 stops sucking the lower surface of the bag 300, and the bag 300 is suspended in half-empty by the suction force of the bag-opening suction cup module 45 in the pushing and bagging unit 5 at this time, so far, the reagent sheet bagging process is completed.

Next, referring to fig. 7, 9, and 2, the blocking cylinder 46 in the bag opening conveying unit 4 is activated, the shutter 47 is driven to fall, and then the air slide table 41 is activated. The conveying table 42 is driven to move leftwards to be above the sealing station 63, then, the bag opening sucker module 45 stops sucking the upper surface of the packaging bag 300, the packaging bag 300 falls onto the sealing station 63 under the action of gravity, and at the moment, the packaging bag slides to the appointed position of the sealing station 63 under the action of the chamfering positioning groove of the sealing station 63.

Referring to fig. 7 and 6, the blocking cylinder 46 in the bag opening and conveying unit 4 is started, the baffle 47 is driven to rise, and then the pneumatic slide table 41 is started. The conveyor table 42 is driven to displace rightward to just above the bagging station 35. At this time, the bag opening and conveying unit 4 leaves the vacuumizing thermoplastic sealing unit 6, and the next round of bagging is performed in cooperation with other units.

With reference to fig. 9 and 10, the pressing cylinder 61 in the vacuumizing thermoplastic sealing unit 6 is started to drive the sealing cover 62 to move downwards until the sealing strips at the edge of the sealing cover 62 completely fit the sealing station 63. The package with the reagent plate and desiccant therein is now completely enclosed by the seal 62 at the sealing station 63. The vacuum nozzle 64 is then activated to create a substantial negative pressure, which is generated simultaneously within the seal cap 62 by the vacuum nozzle 66. At the same time, the seal cylinder 65 is activated to displace the heat seal 66 downwardly, pressing down against the mouth of the bag 300, but leaving a thread void. At this time, since the initial state of the inside of the packing bag 300 is still the atmospheric pressure, the air inside the packing bag 300 is discharged from the air gap by the air pressure difference due to the rapid decrease of the air pressure outside thereof, and the inside of the packing bag 300 becomes a form similar to a vacuum at this time.

Referring to fig. 9, 10, 7 and 2, the heat sealing strip 66 is energized to generate huge heat, the mouth of the package 300 is instantaneously melted under the effect of high temperature, at this time, the heat sealing strip 66 is de-energized, the upper and lower surfaces of the mouth of the package 300 are rapidly cooled and tightly bonded together, and then the sealing cylinder 65 and the pressing cylinder 61 are started to drive the heat sealing strip 66 and the sealing cover 62 to be lifted. Subsequently, the baffle 47 of the bag opening conveying unit 4 pushes the packaged finished product away from the sealing station 63 along with the next displacement, so that the reagent plate 100, the drying agent 200 and the packaging bag 300 are packaged into finished products after a series of processes of feeding, bagging, vacuumizing, thermoplastic sealing and the like, the automation of the processes is realized, the production efficiency and the yield are greatly improved, and the labor cost and the error rate are reduced.

The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, and yet fall within the scope of the invention.
