[0044] Refer to Figures 1 to 7 , the embodiment of the present utility model provides a vacuum packaging production line for petri dishes, which includes a stacking module 1, a labeling module 2, and a packaging module 3 arranged in sequence along the conveying direction; the labeling module 2 is provided with a first rotating device 21, and a first feeding station 211, a labeling operation, a heat shrinking station 214, and a first discharging station 215 are arranged in sequence along the rotation direction of the first rotating device 21. The stacking module 1 and the packaging module 3 are respectively connected corresponding to the first feeding station 211 and the first discharging station 215;

[0045] Among them, the packaging module 3 includes a packaging bag feeding device 100, a second rotating device 200, a plurality of first clamping jaws 210 arranged on the second rotating device 200, and a first material taking device arranged above the second rotating device 200. The first material taking device is used to take out the petri dishes on the first discharging station 215 of the first rotating device 21 and transfer them into the packaging bags clamped by the first clamping jaws 210. A bag taking station 32, a bag loading station 33, a vacuum pumping station 34, a sealing station 35, and a second discharging station 36 are arranged in sequence along the rotation direction of the second rotating device 200. A vacuum pumping machine and a heat sealing machine are respectively arranged at the vacuum pumping station 34 and the sealing station 35.

[0046] Single loose petri dishes are automatically fed into the stacking module 1 for stacking and palletizing. After palletizing to the preset quantity, the stacked and palletized petri dishes are transferred to the labeling module 2. The labeling module 2 sleevs a film on the outside of the petri dishes and heat shrinks and fixes the film on the petri dishes. Subsequently, the petri dishes are transferred to the packaging module 3 for bagging and packing. The whole process is automated, without manual operation, effectively improving the automation degree of the enterprise and effectively improving the production efficiency.

[0047] According to some embodiments of the present application, the packaging bag loading device 100 includes a packaging bag placing frame 110, a bag suction mechanism disposed below the packaging bag placing frame 110, and a first manipulator 120 disposed between the bag suction mechanism and the first clamp 210. The bottom of the packaging bag placing frame 110 is provided with an outlet for the packaging bag to be output. The bag suction mechanism is used to suck out the packaging bag at the bottom layer in the packaging bag placing frame 110. The first manipulator 120 is used to transfer the packaging bag sucked out by the bag suction mechanism to the clamping range of the first clamp 210. Specifically, the bag suction mechanism is composed of a first lifting cylinder 130 and an adsorption assembly 140 disposed at the output end of the first lifting cylinder 130. The first lifting cylinder 130 drives the adsorption assembly 140 to approach or move away from the packaging bag at the bottom layer. Among them, the adsorption assembly 140 is composed of a mounting bracket and a suction nozzle fixed on the mounting bracket, and the suction nozzle is connected to an external negative pressure device. The working principle of the packaging bag loading device 100 is as follows: a worker places a packaging bag in the packaging bag placing frame 110. When the first clamping jaw 210 in the neutral state is driven by the second rotating device 200 to rotate to the bag taking station 32, the first manipulator 120 and the bag suction mechanism are started, and the bag suction mechanism sucks out the packaging bag at the bottom layer of the packaging bag placing frame 110. Then, the first manipulator 120 drives the bag suction mechanism to move to the bag taking station 32, and the first clamping jaw 210 clamps and takes away the packaging bag of the bag suction mechanism. The second rotating device 200 is started again and the first clamping jaw of the bag taking station is used to hold the packaging bag. 210 transfers to the bagging station 33 to wait for the first material taking device to transfer the culture dish into the packaging bag. After the bagging is completed, the second rotating device 200 starts to transfer the packaging bag containing the culture dish to the vacuum station 34 and the sealing station 35, and vacuumizes and heat seals in turn, and finally transfers it to the second unloading station 36, and the second unloading station 36 is provided with a unloading conveyor belt 31. After arriving at the second unloading station 36, the first clamp 210 releases the packaging bag, and the packaging bag falls onto the unloading conveyor belt 31. At this point, the packaging of the culture dish is completed, with a compact structure and a high degree of automation.

[0048] Among them, it is important to note that the opening of the packaging bag should face the same direction according to the placement requirements to ensure that the first clamp 210 clamps the opening of the packaging bag and ensure that the subsequent culture dishes can smoothly enter the packaging bag.

[0049] According to some embodiments of the present application, the labeling module 2 and the packaging module 3 are connected via a first conveyor belt 300 , and the first material taking device is mounted above the first conveyor belt 300 .

[0050] Specifically, the first material taking device includes a first transplanting mechanism and a second transplanting mechanism. The first transplanting mechanism includes a second lifting cylinder 310 and a second gripper 320 disposed at the output end of the second lifting cylinder 310. The second lifting cylinder 310 drives the second gripper 320 to reciprocate in the longitudinal direction. The second gripper 320 is used to take out the culture dish on the first conveyor belt 300. The second transplanting mechanism is used to transfer the culture dish on the second gripper 320 into the packaging bag waiting for the culture dish. Further, the second transplanting mechanism includes a transplanting bracket 330 erected above the first conveyor belt 300, a transplanting cylinder 340 disposed on the transplanting bracket 330, a third lifting cylinder 350 disposed at the output end of the transplanting cylinder 340, and a third gripper 360 disposed at the output end of the third lifting cylinder 350. After the third gripper 360 takes out the culture dish from the second gripper 320, it is driven by the transplanting cylinder 340 to be transferred to the bagging station 33 for bagging. The culture dish completed with film sleeving and heat shrinkage fixing is transported to the packaging module 3 through the first conveyor belt 300. When the culture dish is transported to one end of the first conveyor belt 300 close to the second rotating device 200, the first transplanting mechanism first clamps and lifts the culture dish closest to the second rotating device 200 to a preset height to wait for the second transplanting mechanism to reset and take the material. The specific working principle is as follows: the second lifting cylinder 310 drives the second gripper 320 to descend. After the second gripper 320 takes away the culture dish on the first conveyor belt 300, the second lifting cylinder 310 drives the second gripper 320 to rise to the waiting height. The transplanting cylinder 340 drives the third gripper 360 to move above the second gripper 320. The third lifting cylinder 350 drives the third gripper 360 to descend. After the third gripper 360 takes away the culture dish on the second gripper 320, the third lifting cylinder 350 resets. Finally, the transplanting cylinder 340 is activated to drive the third gripper 360 to move towards the bagging station 33. When it reaches above the bagging station 33, the third lifting cylinder 350 drives the third gripper 360 to descend close to the packaging bag, and the third gripper 360 releases to make the culture dish fall into the packaging bag.

[0051] According to some embodiments of the present application, to ensure that the petri dish can smoothly enter the packaging bag, the packaging module 3 is further provided with a bagging auxiliary mechanism 400. The bagging auxiliary mechanism 400 includes a fourth lifting cylinder 410 disposed adjacent to the bagging station 33, and a conical funnel 420 disposed at the output end of the fourth lifting cylinder 410. The minimum diameter section of the conical funnel 420 faces the packaging bag clamped by the first jaw 210. The fourth lifting cylinder 410 drives the conical funnel 420 to move towards the packaging bag and inserts the discharge port of the conical funnel 420 into the bag opening of the packaging bag. Further, a bag supporting mechanism 500 is disposed at the bagging station 33. The bag supporting mechanism 500 includes a fifth lifting cylinder 510 and an adsorption tube 520 disposed at the output end of the fifth lifting cylinder 510. The two adsorption tubes 520 are disposed opposite to each other, and the two adsorption tubes 520 respectively adsorb both sides of the bag opening of the packaging bag to open the bag opening of the packaging bag. The specific working principle is as follows: When the third jaw 360 reaches the position for placing the petri dish, the fifth lifting cylinder 510 drives the adsorption tube 520 to descend to both sides of the packaging bag. The adsorption tube 520 opens the bag opening of the packaging bag due to the negative pressure adsorption of the adsorption tube 520. At this time, the fourth lifting cylinder 410 drives the conical funnel 420 to descend, so that after the end of the conical funnel 420 is inserted into the packaging bag, the third jaw 360 is released, and the petri dish falls onto the conical funnel 420 and accurately falls into the packaging bag through the conical funnel 420. It should be noted that the minimum diameter of the conical funnel 420 is greater than the maximum diameter of the petri dish.

[0052] According to some embodiments of the present application, the stacking module 1 is composed of a feeding conveyor belt 11, a stacking device, and a buffer device 700. The stacking device is arranged between the feeding conveyor belt 11 and the buffer device 700. Specifically, the stacking device includes a frame 600, a sixth lifting cylinder 610 installed on the frame 600, and a stacking platform 620 arranged at the output end of the sixth lifting cylinder 610. The sixth lifting cylinder 610 drives the stacking platform 620 to move in the longitudinal direction. Further, the buffer device 700 includes a buffer conveyor belt 710 and two baffles 720 fixed on both sides of the buffer conveyor belt 710. Among them, the two baffles 720 are arranged oppositely so that the space between the two baffles 720 forms a buffer bin 730. In addition, a transfer device for transferring petri dishes is arranged between the stacking device and the buffer device 700. Specifically, the transfer device includes a loose part transfer mechanism and a finished product transfer mechanism. The loose part transfer mechanism is used to transfer a single petri dish on the feeding conveyor belt 11 to the stacking platform 620 for stacking and palletizing, and the finished product transfer mechanism is used to transfer the petri dishes that have been stacked and palletized on the stacking platform 620 to the buffer device 700. Further, the loose part transfer mechanism is composed of a first translation cylinder 630 arranged on the frame 600, a seventh lifting cylinder 640 arranged at the output end of the first translation cylinder 630, and a picking component 650 arranged at the output end of the seventh lifting cylinder 640. The finished product transfer mechanism is composed of a second translation cylinder 111 arranged on the feeding conveyor belt 11 and a first push plate 112 arranged at the output end of the second translation cylinder 111.

[0053] The working principle of the stacking module 1 is as follows: After the unstacked petri dishes are conveyed by the feeding conveyor belt to one end close to the stacking platform 620, the first translation cylinder 630 drives the picking component 650 to move above the petri dish, and the seventh lifting cylinder 640 drives the picking component 650 to descend. After the picking component 650 sucks the petri dish on the feeding conveyor belt 11 by negative pressure, the seventh lifting cylinder 640 makes the picking component 650 rise to a certain height, and then the first translation cylinder 630 drives the petri dish to move above the stacking platform 620. The seventh lifting cylinder 640 makes the petri dish descend and approach the stacking platform 620, and the picking component 650 releases the petri dish so that the petri dish is placed on the stacking platform 620. This process is repeated to complete the quantitative stacking and palletizing of petri dishes. Among them, as the stacking height of the petri dishes on the stacking platform 620 increases, the sixth lifting cylinder 610 drives the stacking platform 620 to descend accordingly, and finally makes the top plane of the stacking platform 620 flush with the buffer conveyor belt 710 at the same horizontal plane. After the stacking and palletizing are completed, the second translation cylinder 111 is started to push the petri dishes on the stacking platform 620 onto the buffer conveyor belt 710. When the petri dishes are successfully transferred to the buffer conveyor belt 710, the buffer conveyor belt 710 is started and makes the petri dishes move a preset distance towards the labeling module 2.

[0054] Further, to prevent the finished product transfer mechanism from collapsing when transferring the petri dishes, the finished product transfer mechanism is also provided with an anti-tipping component. Specifically, the anti-tipping component is composed of an eighth lifting cylinder 660 provided on the frame 600, a third translation cylinder 670 provided on the output end of the eighth lifting cylinder 660, and a second push plate 680 provided on the output end of the third translation cylinder 670. When the second translation cylinder 111 is activated and the petri dish is pushed onto the buffer conveyor belt 710, the eighth lifting cylinder 660 is activated simultaneously to lower the third translation cylinder 670 to a preset height. Subsequently, the third translation cylinder 670 is activated to move the second push plate 680 close to the petri dish. When the first push plate 112 and the second push plate 680 reach both sides of the petri dish and jointly clamp the petri dish, the first push plate 112 and the second push plate 680 move towards the buffer conveyor belt 710 simultaneously driven by the second translation cylinder 111 and the third translation cylinder 670 respectively, and stably transfer the petri dish onto the buffer conveyor belt 710.

[0055] According to some embodiments of the present application, the labeling module 2 includes a first rotating device 21, a plurality of clamping mechanisms 800 provided on the first rotating device 21, a labeling device 22, a sorting device 23, and a heat shrinking device 24 arranged in sequence along the rotation direction of the first rotating device 21. A transfer manipulator 5 and a feeding mechanism 900 are arranged between the labeling module 2 and the buffer device 700, and the transfer manipulator 5 is used to transfer the petri dishes on the buffer device 700 to the feeding mechanism 900. Specifically, the feeding mechanism 900 is composed of a feeding conveyor belt 910, a pushing component provided at the discharging end of the feeding conveyor belt 910, and a feeding component. Further, the pushing component is composed of a receiving table 920, a pushing cylinder 930 provided on the receiving table 920, and a third push plate 940 provided on the output end of the pushing cylinder 930, while the feeding component is composed of a feeding table 950, a pushing cylinder 930 provided on the feeding table 950, and a third push plate 940 provided on the output end of the pushing cylinder 930.

[0056] Specifically, multiple material clamping mechanisms 800 are arranged at intervals around the axis of the first rotating device 21. A first loading station 211, a labeling station 212, a sorting station 213, a heat shrinking station 214, and a first unloading station 215 are sequentially arranged along the rotation direction of the first rotating device 21. Correspondingly, a labeling device 22 and a heat shrinking device 24 are respectively arranged at the labeling station 212 and the heat shrinking station 214. Optionally, the heat shrinking device 24 can be a hot air blower. Among them, a sorting device 23 is arranged at the sorting station 213. Specifically, the sorting device 23 is composed of a ninth lifting cylinder 231 and a beating rod 232 arranged at the output end of the ninth lifting cylinder 231. When the Petri dish with the film sleeved is transferred from the labeling station 212 to the sorting station 213, the ninth lifting cylinder 231 is activated to drive the beating rod 232 to move up and down, so that the beating rod 232 reciprocally beats the top of the Petri dish, making the packaging film flush with the top of the Petri dish to ensure that after heat shrinking, the packaging film completely wraps the outside of the Petri dish.

[0057] Further, the material clamping mechanism 800 includes a base 810 fixed on the first rotating device 21, a clamping cylinder 820 arranged on the base 810, and a material clamping rod 830 installed at the output end of the clamping cylinder 820. As shown in the figure, two clamping cylinders 820 are arranged on the base 810, and two material clamping rods 830 are arranged on each clamping cylinder 820. The space between the material clamping rods 830 forms a sorting cavity 840 that can accommodate the Petri dish. Specifically, the clamping cylinder 820 drives the material clamping rod 830 to move, so that the distance between the opposite material clamping rods 830 changes, thereby changing the size of the space of the sorting cavity 840.

[0058] The specific working principle of the label sleeving module 2 is as follows: After the transfer manipulator 5 grabs the petri dish from the buffer device 700 and places it on the feeding conveyor belt 910, the petri dish is transported to the material receiving table 920. Then, the pusher cylinder 930 on the material receiving table 920 is activated to push the petri dish to the waiting table 950 for transfer. When the first rotating device 21 drives the clamping mechanism 800 without a petri dish to rotate to the first feeding station 211, the clamp cylinder 820 is activated to increase the distance between the relatively arranged clamping rods 830. Subsequently, the pusher cylinder 930 on the waiting table 950 is activated to push the petri dish on the waiting table 950 into the sorting cavity 840. When the petri dish completely enters the sorting cavity 840, the clamp cylinder 820 resets the clamping rods 830 to clamp the petri dish. Then, the first rotating device 21 is activated again to make the clamping mechanism 800 with the placed petri dish rotate to the label sleeving station 212, the heat shrinkage station 214, and the first discharging station 215 in sequence to perform the label sleeving process, the external film heat shrinkage process of the petri dish, and the finished product discharging respectively. It should be noted that when the petri dish is transferred to the label sleeving station, the clamp cylinder 820 will be activated again to make the clamping rods 830 no longer clamp the petri dish, so as to facilitate the label sleeving device 22 to perform label sleeving. After the petri dish completes the label sleeving process, it is transferred to the first discharging station 215, and the first discharging station 215 is correspondingly connected to the feeding end of the first conveyor belt 300. Specifically, a transfer manipulator 5 is also provided at the feeding end of the first conveyor belt 300. The transfer manipulator 5 takes out the petri dish at the first discharging station 215 from the clamping mechanism 800 and transfers it onto the first conveyor belt 300.

[0059] Furthermore, a transition component is provided on the waiting component. The transition component consists of a transition cylinder 960 fixed to the bottom of the waiting table 950 and a transition connecting plate 970 arranged at the output end of the transition cylinder 960. The transition cylinder 960 drives the transition connecting plate 970 to reciprocate to change the connection state between the waiting table 950 and the sorting cavity 840. The specific working principle is as follows: When the sorting cavity 840 in the neutral state rotates to the first feeding station 211, the sorting cavity 840 opens. Then, the transition cylinder 960 is activated to make the end of the transition connecting plate 970 extend into the sorting cavity 840. The pusher cylinder 930 on the waiting table 950 is activated to push the petri dish on the waiting table 950 into the sorting cavity 840.
