It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0023] Unless otherwise specified, the instruments, reagents, and materials used in the following embodiments are all conventional instruments, reagents, and materials already available in the prior art and can be obtained through legitimate commercial channels. Unless otherwise specified, the experimental methods and detection methods used in the following embodiments are all conventional experimental methods and detection methods already available in the prior art.

[0024] Example:

[0025] The rinsing module includes a workbench 1, which is fixedly installed in a sterile enclosure or other enclosed space that meets sterile conditions.

[0026] The workbench 1 has a square metal tabletop, which facilitates the symmetrical arrangement of processing positions. The indexing plate 2 is centrally located at the top of the workbench 1.

[0027] The indexing plate 2 has four arc-shaped grooves on its periphery. The arc of each groove is greater than 180 degrees, and the diameter of the groove is adapted to the size of the culture dish, thus confining the culture dish within the groove and allowing it to rotate with the indexing plate 2. Because of the four arc-shaped grooves, the indexing plate 2 stops every 90 degrees, with the stopping position located in the center of one side of the workbench 1, achieving precise production cycle.

[0028] The workbench 1 has a circular opening 3 in the middle of a portion of its side. The circular opening 3 is coaxially corresponding to the arc-shaped groove that stops at that position. Each time the indexing plate 2 stops, the arc-shaped groove and the circular opening 3 are coaxially corresponding vertically. The circular opening 3 is used to provide space for other components to be centered relative to the petri dish.

[0029] Below the circular opening 3, a bracket 4 is fixedly installed relative to the workbench 1. A sliding seat 5 is fixed to one end of the bracket 4 near the side of the workbench 1. A U-shaped groove 6 is provided on the side of the sliding seat 5 near the side of the workbench 1. Opposite sliding grooves are provided on both sides of the U-shaped groove 6. An arc-shaped frame 7 that slides and engages with the sliding seat 5 passes through the U-shaped groove 6. Sliding strips 8 that slide and connect with the sliding grooves are provided on both sides of the arc-shaped frame 7. The sliding grooves, sliding strips 8 and arc-shaped frame 7 are all coaxial arcs. The arc-shaped frame 7 and sliding strips 8 are arc structures with an arc degree of not less than 120 degrees.

[0030] A lower gear 10 is rotatably mounted on the bracket 4, and a lower motor for driving the lower gear 10 is fixed on the bracket 4. An arc-shaped gear ring 9 that meshes with the lower gear 10 is provided on the side of the arc-shaped frame 7 near the axis of the indexing plate 2, thereby driving the arc-shaped frame 7 and enabling it to move through the circular opening 3 along an arc-shaped trajectory. A lower suction cup 15 is mounted on the top of the arc-shaped frame 7, and the lower suction cup 15 has the following two stroke positions based on the swing of the arc-shaped frame 7:

[0031] Horizontal position: When the suction cup opening is coplanar with the bracket, the position of the suction cup is defined as horizontal.

[0032] Tilt position: When the curved frame 7 slides outward until the suction cup opening is tilted downward relative to the vertical surface, it is defined as the tilt position. In this position, the culture dish held by the suction cup 15 is also tilted downward with the opening facing down. This facilitates rinsing and / or pouring liquid outward.

[0033] A vertical plate 11 is fixed to the corner of the workbench 1 on one side of the circular opening 3. A beam plate 12 is fixed to the top of the vertical plate 11. The beam plate 12 extends along the side of the corresponding workbench 1. An opening cylinder 13 is provided on the beam plate 12. The opening cylinder 13 is a hydraulic cylinder. An opening cylinder rod is vertically and horizontally connected to the bottom of the opening cylinder 13. An upper suction cup 14 is installed at the bottom of the opening cylinder rod. The upper suction cup 14 corresponds vertically to the circular opening 3. The opening / box lid action is completed by lifting and suction.

[0034] Both the upper suction cup 14 and the lower suction cup 15 can be made of Φ60mm food-grade silicone rubber annular soft lip suction cups. The lower suction cup 15 and the upper suction cup 14 are respectively connected to a negative pressure system, which uses -50kPa vacuum + 3N floating pre-pressure + 0.2s fast exhaust solenoid valve to safely, quickly and repeatedly adsorb Φ90mm culture dishes, realizing the switching of adsorption or release of culture dishes.

[0035] If rinsing is required, a rinsing assembly can be added to the upright plate 11. If line marking is required, a robotic arm can be installed on the upright plate 11, which is located at a corner and provides a mounting position while avoiding the operation position.

[0036] This example uses rinsing as an example. A rinsing assembly is designed to be installed on the upright plate 11. The rinsing assembly includes a connector 16, to which a water inlet pipe and a serpentine tube 17 are connected. The curvature of the serpentine tube 17 is freely adjustable, and a nozzle 18 is provided at the end of the serpentine tube 17. The nozzle 18 can be a straight columnar nozzle 18 or an umbrella-shaped shower nozzle 18. Water can be injected into the petri dish through the nozzle 18 to achieve rinsing.

[0037] The outer side of the circular opening 3 is provided with a hanging groove 19 fixed below the workbench 1. The hanging groove 19 is an open groove structure. A liquid collection box 20 is placed inside the hanging groove 19. The top of the liquid collection box 20 is an open structure, which is used to collect the liquid poured from the petri dish.

[0038] The hanging groove 19 is fixed to both sides of the workstation slot opening edge by bolts on the side closest to the worktable 1, thereby fixing the hanging groove 19. The structure of the hanging groove 19 facilitates the support of the liquid collection box 20, and makes it convenient to quickly pick up and put down the liquid collection box 20.

[0039] The liquid collection box 20 has a downward-extending liquid collection pipe 21 on the side away from the workbench 1. The bottom of the liquid collection pipe 21 is connected to a tank, through which the bacterial liquid is collected. Depending on the work station, the tank can be equipped with a stirring element inside to slowly mix the collected liquid.

[0040] This module uses the rotation of the indexing plate 2 to move the culture dish to two different working positions in a rhythmic manner. When it is in the round opening position, the upper suction cup 14 lifts and pulls the lid of the culture dish, or releases it from below, thus completing the opening and closing action. The opening range can be adjusted by adjusting the stroke of the opening cylinder 13, ensuring efficient and standardized operation.

[0041] After opening the petri dish, the lower suction cup 15 at the bottom can be used to fix the petri dish in place, making it easier to operate the culture medium. In order to coordinate with the tilting action of the petri dish, the arc-shaped frame 7 can be activated to extend outward, so that the petri dish opening can be tilted downward.

[0042] This device enables rapid opening and closing of petri dishes, facilitates rinsing operations, and allows for pouring. It also provides a foundation for other operational procedures, promoting the large-scale, standardized production of petri dishes and improving the yield and quality of bacterial cellulose fermentation.
