[0025] like Figures 1 to 15 As shown, an embodiment of this application provides a medical petri dish packaging system, including a removal mechanism 1 for removing the bottom and lid of the petri dish. A lid closing mechanism 2, a stacking mechanism 3, and a material handling mechanism 4 are sequentially provided on one side of the removal mechanism 1. A feeding conveyor belt 5 is provided between the lid closing mechanism 2 and the stacking mechanism 3. A packaging mechanism 6 is provided above the stacking mechanism 3.

[0026] The extraction mechanism 1 includes an extraction robot 11 capable of XYZ three-axis feed, and the extraction robot 11 is provided with an extraction fixture 12 that can be flipped over.

[0027] The extraction manipulator 11 has an extraction cylinder 13 mounted downwards at its end output shaft. An extraction bracket 14 is fixed to the extraction cylinder 13, and a fixture mounting plate 15 is hinged to the extraction bracket 14. The extraction fixture 12 is fixed to the fixture mounting plate 15. A rack is mounted on the output shaft of the extraction cylinder 13, and a gear 16 is mounted at the hinge of the fixture mounting plate 15. The rack and gear 16 mesh, allowing the extraction cylinder 13 to drive the extraction fixture 12 to either a vertical or horizontal position. When vertical, the bottom and lid of the culture dish are extracted from the injection molding machine 9; when horizontal, the bottom and lid are placed into the closing mechanism 2. The rack, not shown in the figure, is located to the left of the gear 16 and meshes with it.

[0028] The removal fixture 12 includes a fixture plate 121. Several rows of first positioning seats 122 for positioning the bottom and / or lid of the culture dish are provided on the front side of the fixture plate 121. A first pneumatic element 123 is provided on the back side of the fixture plate 121 corresponding to each first positioning seat 122. The first pneumatic element 123 is provided with a pair of first clamping blocks 124 that can be opened or closed for clamping the bottom or lid of the culture dish. The first clamping blocks 124 are located at both ends of the first positioning seat 122.

[0029] In this embodiment, the fixture plate 121 is provided with three columns and four rows of first positioning seats 122, wherein the two rows of first positioning seats 122 at the top correspond to the petri dish lid, and the two rows of first positioning seats 122 at the bottom correspond to the petri dish bottom.

[0030] The closing mechanism 2 includes a first positioning fixture 21 for the bottom of the culture dish, a second positioning fixture 22 for the bottom of the culture dish, a flipping fixture 23 for the culture dish lid, and a positioning fixture 24 for the culture dish lid. The first positioning fixture 21 for the bottom of the culture dish is movably mounted on the base plate 25. The second positioning fixture 22 for the bottom of the culture dish is movably mounted below the first positioning fixture 21 for the bottom of the culture dish. The positioning fixture 24 for the culture dish lid is located on one side of the second positioning fixture 22 for the bottom of the culture dish, and the second positioning fixture 22 for the bottom of the culture dish is higher than the positioning fixture 24 for the culture dish lid. The flipping fixture 23 for the culture dish lid is located above the positioning fixture 24 for the culture dish lid. A closing conveyor belt is provided below the positioning fixture 24 for the culture dish lid.

[0031] Both the first positioning fixture 21 and the second positioning fixture 22 of the petri dish bottom include a bottom positioning plate 211. The bottom positioning plate 211 is provided with a plurality of second positioning seats 212. Second clamping blocks 213 are provided at both ends of the second positioning seats 212. The second clamping block 213 located at one end of the second positioning seat 212 is fixedly connected to the first positioning cylinder 214 located at one end of the bottom positioning plate 211 by a first linkage bar 216. The second clamping block 213 located at the other end of the second positioning seat 212 is fixedly connected to the second positioning cylinder 215 located at the other end of the bottom positioning plate 211 by a second linkage bar 217. Thus, when the two opposing second clamping blocks 213 extend toward the middle of the second positioning seats 212, the bottom of the petri dish will be fixed in the second positioning seats 212. When the two opposing second clamping blocks 213 move away from the middle of the second positioning seats 212, the bottom of the petri dish will fall down through the second positioning seats 212.

[0032] In this embodiment, the first positioning fixture 21 and the second positioning fixture 22 at the bottom of the petri dish have the same structure, and each is provided with six second positioning seats 212.

[0033] The base plate 25 is provided with a tooling bracket 251. The first positioning tooling 21 for the bottom of the culture dish is driven by a motor or cylinder and can be moved up and down on the tooling bracket 251. The second positioning tooling 22 for the bottom of the culture dish is driven by a conveying motor 252 and can be moved left and right laterally below the first positioning tooling 21 for the bottom of the culture dish. So when the bottom of the culture dish is loaded on the second positioning seat 212 of the first positioning tooling 21 for the bottom of the culture dish, the first positioning tooling 21 for the bottom of the culture dish descends, and the first positioning cylinder 214 and the second positioning cylinder 215 work to make the bottom of the culture dish fall on the second positioning seat 212 of the second positioning tooling 22 for the bottom of the culture dish.

[0034] The culture dish lid flipping fixture 23 includes two rotating rods 231, which are driven to rotate by a rotating motor 232 at one end. A third positioning seat 233 is provided on each of the two rotating rods 231.

[0035] The positions and sizes of the twelve first positioning seats 122 on the removal fixture 12, the six second positioning seats 212 on the first positioning fixture 21 of the petri dish bottom, and the six third positioning seats 233 on the rotating rod 231 are adapted to each other, so that the six petri dish bottoms and six petri dish lids removed by the removal fixture 12 at one time can be placed on the six second positioning seats 212 and the six third positioning seats 233 at one time.

[0036] The third positioning seat 233 includes a third pneumatic element 2331, which is fixed to the rotating rod 231. Each third pneumatic element 2331 is provided with three third clamping members 2332 that can open or retract relative to the central axis of the third pneumatic element 2331. When the third clamping members 2332 are above the third pneumatic element 2331, the three third clamping members 2332 are in the open state, and the petri dish lid is placed between the three third clamping members 2332. When the three third clamping members 2332 retract, the petri dish lid is clamped and fixed. The rotating motor 232 drives the rotating rod 231 to rotate, so that the third clamping members 2332 are below the third pneumatic element 2331, causing the petri dish lid to flip over.

[0037] The petri dish lid positioning fixture 24 is provided with a fourth positioning seat 241 corresponding to the third positioning seat 233. The fourth positioning seat 241 is a positioning hole with a diameter that matches the outer diameter of the petri dish lid and the bottom of the petri dish. A first support plate 242 driven by a motor or cylinder is provided on the base plate 25 corresponding to the positioning hole.

[0038] Initially, the first support plate 242 is located at the bottom of the positioning hole. The third clamping member 2332 is open, and the petri dish lid falls into the positioning hole and is held by the first support plate 242. The second positioning fixture 22 of the petri dish bottom is driven by the conveyor motor 252 to move laterally above the petri dish lid positioning fixture 24. The bottom of the petri dish passes through the second positioning seat 212 and falls onto the petri dish lid, completing the lid closing. The first support plate 242 moves downward. When the first support plate 242 is lower than the lid closing conveyor belt, the closed petri dish stays on the lid closing conveyor belt and is conveyed by the lid closing conveyor belt to the feeding conveyor belt 5, which continues to convey it to the stacking mechanism 3.

[0039] The stacking mechanism 3 includes a lifting mechanism 31, which is located at the end of the feeding conveyor belt 5. The lifting mechanism 31 includes a box 311 with a top opening 314. The top of the box 311 is flush with the feeding conveyor belt 5. A pushing mechanism 32 is provided on one side of the feeding conveyor belt 5 to push the covered culture dish into the box 311. The internal width of the housing 311 is adapted to the diameter of the culture dish after the lid is closed. Within the housing 311, a lifting rod 313, driven by a lifting motor 312, is provided for each culture dish and moves up and down accordingly. Figure 13 In the diagram, only one side panel 3111 of the box 311 is shown; the other three side panels 3111 and the bottom are hidden to show the internal structure of the box. The stacked items on top of the lifting rod 313 are the culture dishes after the lid is closed. Similarly, in Figure 4 One side panel 3111 is also hidden in the middle.

[0040] The pushing mechanism 32 includes a pushing motor 321, a pushing rod 322, and a transmission rod 323. The pushing motor 321 is fixed to one side of the housing 311. The pushing rod 322 is positioned facing the top opening 314 of the housing 311. A pushing cam 324 is fixed on the output shaft of the pushing motor 321. The transmission rod 323 is rotatably disposed between the pushing cam 324 and the pushing rod 322. Transmission grooves are provided at both ends of the transmission rod 323. A first transmission block 325 is provided on the cam. A second transmission block 326 is provided on the pushing rod 322. The first transmission block 325 is slidably disposed in the transmission groove at one end of the transmission rod 323, and the second transmission block 326 is slidably disposed in the transmission groove at the other end of the transmission rod 323. When the pusher motor 321 operates, the cam rotates, causing the first transmission block 325 to swing the transmission rod 323. This, in turn, drives the second transmission block 326 to move the pusher rod 322 forward or backward. When moving backward, it clears a passage to allow the capped culture dishes to be conveyed to the front. When moving forward, the pusher rod 322 pushes the capped culture dishes into the opening 314 at the top of the lifting mechanism 31. Previously, the lifting rod 313 of the lifting mechanism 31 was driven by the lifting motor 312 to be below the top opening 314, just one product's height away from the opening 314, so that the capped culture dishes can be smoothly stopped at the top of the lifting rod 313. The lifting mechanism 31 then descends, restoring the height to one product's height from the top opening 314, until a sufficient number of products are stacked.

[0041] A sensor can also be installed at the front end of the push rod 322. When the sensor detects that there is a culture dish at the front end of the push rod 322, the push rod 322 pushes the material forward.

[0042] The packaging mechanism 6 includes a first support 61 and a second support 62 correspondingly arranged on both sides above the box body 311. An upper sealing head assembly for sealing the upper end of the bag-shaped packaging film is provided at the upper end of the first support 61 and the second support 62, and a lower sealing head assembly 64 for sealing the lower end of the bag-shaped packaging film is provided at the lower end of the first support 61 and the second support 62. A film-pulling robot 65 for tightening the packaging film and capable of moving up and down is provided on the first support 61. A film-cutting mechanism for cutting the packaging film and a pre-compression mechanism for pressing the lower end of the packaging film to facilitate vacuuming are provided on the second support 62.

[0043] The pre-compression mechanism includes a long strip 671 that can be moved laterally back and forth by a cylinder, and another long strip 671 is provided on the first bracket 61 corresponding to the long strip 671.

[0044] The film cutting mechanism is located above the upper end cap assembly, and the pre-compression mechanism is located above the lower end cap assembly 64.

[0045] In this embodiment, the upper sealing head assembly and the lower sealing head assembly 64 have the same structure. A heat sealing element 631, which can move laterally back and forth, is provided between the first support 61 and the second support 64. When the two heat sealing elements 631 are closed and pressed on both sides of the packaging film, the packaging film is heated and bonded, thus sealing the end of the packaging film.

[0046] The film cutting mechanism includes a film cutting blade 661 that is driven by a cylinder and can move back and forth, mounted on the second bracket 62. A die-cutting base 662 is provided on the first bracket 61 corresponding to the film cutting blade 661. The die-cutting base 662 can be fixed or can be driven by a cylinder to move laterally back and forth.

[0047] The film-pulling robot 65 includes a left lifting assembly 651 and a right lifting assembly 652 disposed on both sides of the first support 61. The left lifting assembly 651 and the right lifting assembly 652 are synchronously driven to lift and lower by a film-pulling motor 653 disposed at the bottom of the first support 61 through a linkage rod 654. A fourth clamping assembly 655, which is driven by a cylinder and can move laterally back and forth, is correspondingly disposed on the left lifting assembly 651 and the right lifting assembly 652. The fourth clamping assembly 655 clamps the packaging film.

[0048] The fourth clamping assembly 655 includes a fourth pneumatic element, on which a pair of fourth clamping members are provided that can be opened or retracted facing the packaging film. The film-pulling robot 65 can pull the packaging film passing through the top of the first support 61 or the second support 62 downwards. Pulling it down from the upper end between the first support 61 and the second support 62 to the lower end between the first support 61 and the second support 62, and cooperating with the film-opening fixture 68 and the film-hooking fixture 69, the stacked culture dishes that have been lifted above the top opening 314 of the box 311 are then secured.

[0049] In this embodiment, both the left lifting assembly 651 and the right lifting assembly 652 are provided with two of the fourth clamping assemblies 655.

[0050] It also includes a film-opening fixture 68 corresponding to the top opening 314 of the box 311. The film-opening fixture 68 includes a transmission belt driven to rotate by a film-opening motor 681. The transmission belt is located on one side of the top opening 314 of the box 311. A film-opening base 682 is slidably provided on both sides of the top opening 314 of the box 311. A plurality of film-opening suction cups 683 are provided facing each other on the two film-opening bases 682. One film-opening base 682 is fixedly connected to one rotating edge 684 of the transmission belt, and the other film-opening base 682 is fixedly connected to the other rotating edge 684 of the transmission belt.

[0051] When the drive belt is driven to rotate by the film-opening motor 681, the two film-opening bases 682 are fixed on different rotating sides 684, so the two film-opening bases 682 move in opposite directions. For example, when the film-opening motor 681 rotates forward, the two film-opening bases 682 move towards each other, and when the film-opening motor 681 rotates in reverse, the two film-opening bases 682 move away from each other. They move towards each other until the film-opening suction cups 683 on the two film-opening bases 682 close together, so that they are respectively adsorbed on one side of the two layers of packaging film. The movement away from each other causes one end of the packaging film to be pulled open.

[0052] In other embodiments, the two film-opening bases 682 may move in opposite directions when the film-opening motor 681 rotates forward.

[0053] It also includes a film-hooking fixture 69 corresponding to the top opening 314 of the box body 311. The film-hooking fixture 69 includes a first film-hooking cylinder 691 axially mounted on both sides of the box body 311. A second film-hooking cylinder 692 is laterally fixed on the cylinder shaft of the two first film-hooking cylinders 691. The cylinder shafts of the two second film-hooking cylinders 692 face each other and are directed toward the top opening 314 of the box body 311. A film-hooking sheet 693 is fixed on the cylinder shaft of the second film-hooking cylinder 692.

[0054] The length of the hook film 693 is greater than the width of the culture dish. The width of the hook film 693 gradually decreases from the bottom to the top. When two hook films 693 come into contact, their top surfaces adhere to each other, thus ensuring that they can be inserted into the gap at the bottom of the packaging film that has been pulled open.

[0055] The two hooked membranes 693 continue to move forward until the packaging film is opened wide enough for the closed culture dish to pass through. The lifting rod 313 moves upward and pushes the stacked culture dish into the packaging film.

[0056] The material handling mechanism 4 includes a material handling base 42 that is driven to move laterally by a material handling motor 41. A material handling lifting cylinder 45 is provided on the material handling base 42. A clamping cylinder 43 is provided on the output shaft of the material handling lifting cylinder 45. A product clamp 44 that can be opened or closed for clamping the packaged culture dish is provided on the clamping cylinder 43 facing the top of the box 311.

[0057] A vacuum device is provided on one side of the upper end of the housing 311, which can be moved up and down. After the top end of the packaging film is cut and heat-sealed, the stacked culture dishes are lifted up by the packaging film, the product clamp 44 clamps the culture dishes, and the lifting rod 313 moves downward to remove the packaging film. The suction nozzle of the vacuum equipment extends into the packaging film, and the pre-compression mechanism closes the packaging film. After vacuuming is completed, the suction nozzle retracts, and the lower sealing head assembly 64 seals the lower end of the packaging film, thus completing the packaging process for the stacked culture dishes.

[0058] A product conveyor belt 92 is provided on one side of the material handling mechanism 4.

[0059] The material handling mechanism 4 places the culture dish that has completed the packaging process onto the product conveyor belt 92 and transports it to the next process.

[0060] In this embodiment, a sampling inspection platform 8 can also be set up. When the bottom and lid of the culture dish are taken out from the injection molding machine 9, defects such as appearance are detected on the sampling inspection platform 8, and good products flow into the next process.

[0061] The specific vacuum packaging process is as follows: The film-pulling robot 65 pulls the packaging film to a set length, the film-cutting mechanism cuts the packaging film, and the upper sealing assembly heat-seals the upper end of the packaging film. The film-opening suction cup 683 sucks the packaging film open on both sides, the film-hooking fixture 69 enters the packaging film to further pull it open, the lifting mechanism 31 sends the stacked products into the packaging film, the product clamp 44 clamps the products, the lifting mechanism 31 descends and vacuum seals the product, and the material-removing mechanism 4 removes the product and places it on the product conveyor belt.

[0062] This invention is reasonably and ingeniously designed, capable of automatically removing the bottom and lid of the culture dish from the mold, and then automatically completing the processes of closing, stacking, vacuuming, packaging, and unloading the bottom and lid of the culture dish. It has a high degree of automation, reduces manual intervention, and eliminates the need for workers to touch the product, thus avoiding product contamination and damage to the product surface, improving work efficiency and reducing production costs.
