Description

Technical Field

[0001] This invention relates to the field of filling machine technology, and more specifically to a cabinet-type filling machine and a filling method for the cabinet-type filling machine. Background Technology

[0002] A petri dish is a laboratory vessel used for culturing microorganisms or cells. It consists of a disc-shaped body and a lid, with the lid fitting between the body and the dish with a gap.

[0003] The filling of petri dishes involves opening the lid, filling with reagents, and closing the lid. When batch filling is performed, these steps are repeated, and the filled petri dishes are stacked. Manual operation of this process is labor-intensive, prone to reagent contamination, and inefficient. Therefore, automated equipment is now widely used. Current equipment often uses clamping mechanisms to open or close the lid, and different processes are performed at different stations. This results in complex structures, large equipment sizes, and significant space requirements, leading to a poor user experience. Summary of the Invention

[0013] In one embodiment of the present invention, a first photoelectric switch and a second photoelectric switch are further included.

The first photoelectric switch is correspondingly arranged with the push block, and the second photoelectric switch is correspondingly arranged with the second conveying mechanism.

[0014] Secondly, the present invention also provides a filling method for the cabinet-type filling machine, comprising the above-mentioned cabinet-type filling machine, and the following steps: S1. Stack the materials, placing the petri dishes and the lid into the hopper according to the structure of lid, petri dish, lid, petri dish; S2. Material conveying: Initially, the stop block supports the bottom cover. When the petri dish needs to be filled, the cylinder moves the U-shaped block upward. Then, the first motor drives the first belt drive, connecting shaft, and stop block to rotate, releasing the stop block from restraining the cover. The material in the hopper then falls, causing a set of covers and petri dishes to abut against the U-shaped block. Due to the stacked cover and petri dish configuration, there is a gap between the petri dish and the cover. Then, the cylinder moves, and when the U-shaped block descends to the designated position, the output shaft of the first motor reverses, causing the stop block to support and limit the cover again. Then, the piston rod of the cylinder continues to retract, causing the cover and petri dish to fall onto the circular belt. At the same time, the second ultraviolet lamp works to sterilize the petri dish. When the piston rod of the cylinder retracts a designated distance, the second motor drives the circular belt to rotate, thus conveying the cover and petri dish to the designated position. S3. Filling the culture medium: When both first photoelectric switches detect the cover and the culture dish, the second motor stops working and the third motor starts working. The rotation of the output shaft of the third motor drives the first lead screw to rotate. The push block moves linearly under the combined action of the first lead screw, the first slide bar and the first connecting frame. Under the action of the third motor, the push block pushes the cover and the culture dish directly below the filling needle. Then the filling machine body works to fill the culture medium into the culture dish. S4. Transfer the culture medium. Then, the longitudinal linear module and the robotic arm work together. The longitudinal linear module moves the tray up and down, and the robotic arm moves the tray in multiple directions. With the combined action of the longitudinal linear module and the robotic arm, the cap and culture dish after filling are transferred to the settling plate, so that the filled culture dish can be settling. S5. Ventilation and sterilization: During the static period of the petri dish, the blower connected to the outside of the hood works, and the air is sprayed out from the first and second air holes to blow horizontally and vertically into the inner cavity formed by the outer shell to meet the drying requirements of the culture medium. At the same time, the first ultraviolet lamp works to sterilize the inner cavity formed by the outer shell. S6. Sealing: After the culture dish has been left to stand for a specified time, the longitudinal linear module and the robotic arm work together to place the settled lid and culture dish between the lower limiting rod and the stop rod. Then, the fourth motor operates, and the rotation of its output shaft drives the second lead screw to rotate. The push plate moves linearly under the combined action of the second lead screw, the second slide rod, and the second connecting frame. The push plate pushes the lid and the culture dish on it to move. Due to the restriction of the stop rod, the lid and the culture dish on it separate. The push plate continues to work, moving the lid to the second conveying mechanism. When the second photoelectric switch detects the presence of the lid, the second conveying mechanism operates to transport the lid away for reuse. Afterwards, the output shaft of the fourth motor reverses. The push plate moves backward, causing the culture dish to follow. Under the action of the limiting rod, the culture dish is held between the limiting rods. Then, the longitudinal linear module and the robotic arm continue to work, moving another set of settled caps and culture dishes to the culture dish pre-positioned at the limiting rod, thus placing the cap on the culture dish. Then, the fourth motor works, and under the action of the stop rod, the cap is firmly placed on the culture dish. At the same time, the topmost culture dish is held at the stop rod. The capped culture dish is pushed onto the second conveying mechanism. Under the detection of the second photoelectric switch, the second conveying mechanism transports the capped culture dish away, thus sealing the filled culture dish. This process is repeated to seal the settled culture dishes.

[0015] The advantages and positive effects of this invention are: (1) The culture dish is placed in stillness using a feeding and unloading mechanism and a stilling plate. The structure is simple, the equipment is small, and it occupies a small space.

[0016] (2) The petri dish lifting mechanism, petri dish limiting mechanism, first conveying mechanism, pushing mechanism and discharging mechanism are used to automatically seal the petri dishes after filling. The degree of automation is high and manpower is saved.

[0017] (3) The cross and vertical air settings meet the needs of rapid drying of culture medium and control of condensation of finished product, bringing a better user experience. Attached Figure Description

[0024] Specifically, the present invention also provides a filling method for the cabinet-type filling machine, including the above-mentioned cabinet-type filling machine, and the following steps: S1. Stack the materials, placing the petri dishes and the cover into the hopper 140 according to the structure of cover, petri dish, cover, petri dish; S2. Material conveying: Initially, the stop block 1914 supports the bottom cover. When filling the petri dish, the cylinder 1901 moves the U-shaped block 1904 upward. Then, the first motor 1911 drives the first belt drive 1912, connecting shaft 1913, and stop block 1914 to rotate, releasing the stop block 1914 from restraining the cover. The material in the hopper 140 then falls, causing a set of covers and petri dishes to abut against the U-shaped block 1904. Due to the stacked form of the covers and petri dishes, there is a gap between the petri dishes and the covers. After a gap, cylinder 1901 operates. When U-shaped block 1904 descends to the designated position, the output shaft of the first motor 1911 reverses, causing stop block 1914 to support and limit the cover again. Then, the piston rod of cylinder 1901 continues to retract, causing the cover and petri dish to fall onto the circular belt 1924. At the same time, the second ultraviolet lamp 1905 operates to sterilize the petri dish. After the piston rod of cylinder 1901 retracts a designated distance, the second motor 1921 operates to drive the circular belt 1924 to rotate, thereby transporting the cover and petri dish to the designated position. S3. Filling the culture medium: When both first photoelectric switches 19903 detect the cover and the culture dish, the second motor 1921 stops working, and the third motor 1941 starts working. The rotation of the output shaft of the third motor 1941 drives the first lead screw 1942 to rotate. The push block 1945 moves linearly under the combined action of the first lead screw 1942, the first slide rod 1943 and the first connecting frame 1944. Under the action of the third motor 1941, the push block 1945 pushes the cover and the culture dish directly below the filling needle 193. Then the filling machine body 196 works to fill the culture medium into the culture dish. S4. Transfer the culture medium. Then, the longitudinal linear module 172 and the robot arm 173 work. The longitudinal linear module 172 moves the tray 174 up and down, and the robot arm 173 moves the tray 174 in multiple directions. Under the joint action of the longitudinal linear module 172 and the robot arm 173, the cap and culture dish after filling are transferred to the standing plate 160 to allow the filled culture dish to stand. S5. Ventilation and sterilization: During the static period of the petri dish, the blower connected to the wind hood 197 works, and the air is sprayed out from the first air hole 199 and the second air hole 1990 to blow horizontally and vertically into the inner cavity formed by the outer shell 130 to meet the metabolic needs of the culture medium for gas. At the same time, the first ultraviolet lamp 180 works to sterilize the inner cavity formed by the outer shell 130. S6. Sealing: After the culture dish has been left to stand for a specified time, the vertical linear module 172 and the robotic arm 173 work together to place the settled cover and culture dish between the lower limiting rod 19902 and the stop rod 19901. Then, the fourth motor 1951 operates, and the rotation of the output shaft of the fourth motor 1951 drives the second lead screw 1952 to rotate. The push plate 1955 moves linearly under the combined action of the second lead screw 1952, the second slide rod 1953, and the second connecting frame 1954. The push plate 1955 pushes the cover and the culture dish on it to move. Due to the restriction of the stop rod 19901, the cover and the culture dish on it separate. The push plate 1955 continues to work, moving the cover onto the second conveying mechanism 19905. When the second photoelectric switch 19904 detects the presence of the cover, the second conveying mechanism 19905 operates to transport the cover away for reuse. Then, the fourth motor... The output shaft of the machine 1951 reverses, causing the push plate 1955 to move backward, which in turn moves the culture dish backward. Under the action of the limit rod 19902, the culture dish is held between the limit rods 19902. Then, the longitudinal linear module 172 and the robot arm 173 continue to work, moving another set of settled caps and culture dishes to the culture dish pre-positioned at the limit rod 19902, thus covering the culture dish with the cap. Then, the fourth motor 1951 works, and under the action of the stop rod 19901, the cap is firmly placed on the culture dish. At the same time, the topmost culture dish is held at the stop rod 19901. The capped culture dish is pushed onto the second conveying mechanism 19905. Under the detection of the second photoelectric switch 19904, the second conveying mechanism 19905 transports the capped culture dish away, thus sealing the filled culture dish. This process is repeated to seal the settled culture dishes.

[0025] The working principle and process of this invention are as follows: In use, the petri dish and the cover are placed in the hopper 140 in the structure of cover, petri dish, cover, petri dish. Initially, the stop block 1914 supports the bottom cover. When the petri dish needs to be filled, the cylinder 1901 drives the U-shaped block 1904 to move upward. Then, the first motor 1911 drives the first belt drive 1912, the connecting shaft 1913, and the stop block 1914 to rotate, releasing the constraint of the cover. Then, the material in the hopper 140 falls, causing a set of covers and petri dishes to abut against the U-shaped block 1904. Due to the stacked form of the cover and petri dish, there is a gap between the petri dish and the cover. Then, the cylinder 1901 works, and when the U-shaped block... When block 1904 descends to the designated position, the output shaft of the first motor 1911 reverses, causing stop block 1914 to support and limit the cover again. Then, the piston rod of cylinder 1901 continues to retract, causing the cover and culture dish to fall onto the circular belt 1924. Simultaneously, the second ultraviolet lamp 1905 sterilizes the culture dish. After the piston rod of cylinder 1901 retracts a designated distance, the second motor 1921 rotates the circular belt 1924, transporting the cover and culture dish to the designated position. When both first photoelectric switches 19903 detect the cover and culture dish, the second motor 1921 stops working, and the third motor 1941 starts working. The rotation of the output shaft of the third motor 1941 drives the first lead screw 1942 to rotate, pushing block 19... 45. Under the combined action of the first lead screw 1942, the first slide bar 1943, and the first connecting frame 1944, linear movement is achieved. Under the action of the third motor 1941, the pusher block 1945 pushes the cover and culture dish directly below the filling needle 193. Then, the filling machine body 196 works to fill the culture medium into the culture dish. After that, the longitudinal linear module 172 and the robot arm 173 work. The longitudinal linear module 172 moves the tray 174 up and down, and the robot arm 173 moves the tray 174 in multiple directions. Under the combined action of the longitudinal linear module 172 and the robot arm 173, the filled cover and culture dish are transferred to the settling plate 160, so that the filled culture dish can be settling. During the filling process, the blower connected to the external fan 197 operates, and air is ejected from the first vent 199 and the second vent 1990, blowing horizontally and vertically into the inner cavity formed by the outer shell 130 to meet the metabolic needs of the culture medium. At the same time, the first ultraviolet lamp 180 operates to sterilize the inner cavity formed by the outer shell 130. This process is repeated to continuously fill the culture dishes. After the culture dishes have been left to stand for a specified time, the lid and culture dishes, which have been left to stand, are placed between the lower limiting rod 19902 and the stop rod 19901 under the combined action of the longitudinal linear module 172 and the robotic arm 173. Then, the fourth motor 1951 operates, and the rotation of the output shaft of the fourth motor 1951 drives the second lead screw 1952 to rotate.The pusher plate 1955 moves linearly under the combined action of the second lead screw 1952, the second slide bar 1953, and the second connecting frame 1954. The pusher plate 1955 pushes the cover and the culture dish on it to move. Due to the restriction of the stop bar 19901, the cover and the culture dish on it separate. The pusher plate 1955 continues to work, moving the cover onto the second conveying mechanism 19905. When the second photoelectric switch 19904 detects the presence of the cover, the second conveying mechanism 19905 works to transport the cover away for reuse. Then, the output shaft of the fourth motor 1951 reverses, causing the pusher plate 1955 to move backward, pulling the culture dish backward as well. Under the action of the limit bar 19902, the culture dish is held between the limit bars 19902. Then, the longitudinal linear module 172 and the robot arm 173 continue to work, moving another set of stationary covers and culture dishes onto the culture dish pre-positioned at the limit bar 19902, thus placing the cover on the culture dish. Afterward, the fourth motor 1951... In operation, under the action of the stop lever 19901, the lid is securely placed on the culture dish, while the topmost culture dish remains at the stop lever 19901. The capped culture dish is pushed onto the second conveying mechanism 19905. Under the detection of the second photoelectric switch 19904, the second conveying mechanism 19905 transports the capped culture dish away, thus sealing the filled culture dishes. This process is repeated to seal the culture dishes after they have settled. This cabinet-type filling machine uses the loading and unloading mechanism 170 and the settling plate 160 to settle the culture dishes. It has a simple structure, small size, and occupies little space. The culture dish lifting mechanism 190, culture dish limiting mechanism 191, first conveying mechanism 192, pushing mechanism 194, and discharging mechanism 195 automatically seal the filled culture dishes, achieving a high degree of automation and saving manpower. The horizontal and vertical airflow settings meet the gas metabolism requirements of the culture medium, providing users with a better experience.

All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of this patent.

10. A filling method for the cabinet-type filling machine, characterized in that, include The cabinet-type filling machine according to any one of claims 1-9, and the following steps: S1. Stack the materials and place the petri dishes and the cover into the hopper (140) according to the structure of cover, petri dish, cover, petri dish; S2. Material conveying: Initially, the stop (1914) supports the bottom cover. When the petri dish needs to be filled, the cylinder (1901) drives the U-shaped block (1904) upward. Then, the first motor (1911) drives the first belt drive (1912), connecting shaft (1913), and stop (1914) to rotate. The stop (1914) releases the constraint on the cover, and then the material in the hopper (140) falls, causing a set of covers and petri dishes to abut against the U-shaped block (1904). Due to the stacked form of the covers and petri dishes, there is a gap between the petri dishes and the covers. After a gap, the cylinder (1901) works. When the U-shaped block (1904) descends to the designated position, the output shaft of the first motor (1911) reverses, causing the stop block (1914) to support and limit the cover again. Then, the piston rod of the cylinder (1901) continues to retract, causing the cover and the petri dish to fall onto the circular belt (1924). At the same time, the second ultraviolet lamp (1905) works to sterilize the petri dish. After the piston rod of the cylinder (1901) retracts a designated distance, the second motor (1921) works to drive the circular belt (1924) to rotate, thus transporting the cover and the petri dish to the designated position. S3. Filling the culture medium: When both first photoelectric switches (19903) detect the cover and the culture dish, the second motor (1921) stops working and the third motor (1941) starts working. The rotation of the output shaft of the third motor (1941) drives the first lead screw (1942) to rotate. The push block (1945) moves linearly under the combined action of the first lead screw (1942), the first slide bar (1943) and the first connecting frame (1944). Under the action of the third motor (1941), the push block (1945) pushes the cover and the culture dish directly below the filling needle (193). Then the filling machine body (196) works to fill the culture medium into the culture dish. S4. Transfer the culture medium. Then, the longitudinal linear module (172) and the robot arm (173) work. The longitudinal linear module (172) moves the tray (174) up and down, and the robot arm (173) moves the tray (174) in multiple directions. Under the combined action of the longitudinal linear module (172) and the robot arm (173), the cap and culture dish after filling are transferred to the standing plate (160) to achieve the standing of the culture dish after filling. S5. Ventilation and sterilization: During the static period of the petri dish, the blower connected to the wind hood (197) works, and the air is sprayed out from the first air hole (199) and the second air hole (1990) to blow air horizontally and vertically into the inner cavity formed by the outer shell (130) to meet the metabolic needs of the culture medium for gas. At the same time, the first ultraviolet lamp (180) works to sterilize the inner cavity formed by the outer shell (130). S6. Sealing: After the culture dish has been left to stand for a specified time, the cap and culture dish, under the combined action of the longitudinal linear module (172) and the robot arm (173), are placed between the lower limiting rod (19902) and the stop rod (19901). Then, the fourth motor (1951) works, and the rotation of the output shaft of the fourth motor (1951) drives the second lead screw (1952) to rotate. The push plate (1955) is positioned between the second lead screw (1952) and the second slide rod (19901). 53) Linear movement is achieved through the combined action of the second connecting frame (1954). The pusher plate (1955) pushes the cover and the culture dish on it to move. Due to the restriction of the stop bar (19901), the cover and the culture dish on it are separated. The pusher plate (1955) continues to work, moving the cover to the second conveying mechanism (19905). When the second photoelectric switch (19904) detects the presence of the cover, the second conveying mechanism (19905) works to transport the cover away for reuse. The output shaft of the fourth motor (1951) reverses, causing the push plate (1955) to move backward, which in turn moves the culture dish backward. Under the action of the limiting rod (19902), the culture dish is held between the limiting rods (19902). Then the longitudinal linear module (172) and the robot arm (173) continue to work, moving another set of settled lids and culture dishes to the culture dish pre-positioned at the limiting rod (19902), thus placing the lid on the culture dish. Then the fourth motor (1951) reverses. 951) Under the action of the stop bar (19901), the cover is firmly placed on the culture dish, and the topmost culture dish is left at the stop bar (19901). The culture dish with the cover is pushed onto the second conveying mechanism (19905). Under the detection of the second photoelectric switch (19904), the second conveying mechanism (19905) transports the culture dish with the cover away, thereby sealing the filled culture dish. In this way, the culture dishes that have been left to stand are continuously sealed.
