Description

Technical Field

[0001] The present invention relates to the technical field of food microorganism detection, and specifically provides an automatic scribing inoculation device for food microorganism detection. Background Art

[0002] Food microorganisms are the general term for microorganisms related to food, including production-type food microorganisms, Acetobacter, yeasts, etc., molds that cause food spoilage, bacteria, etc., and foodborne pathogenic microorganisms, Escherichia coli, Clostridium botulinum, etc. Food microorganism detection is to detect the microbial indicators of the hands of production workshop operators and mechanical equipment in direct contact with food, and to monitor pathogenic microorganisms in the production area environment to meet the specified standards, so as to control the quality of food products and ensure the safety of food production.

[0003] Chinese Patent CN104403938B discloses an intelligent robot for microbial sample processing, including a machine table, on which are connected an automatic sample test tube lid removal and capping and handling device, an automatic sample test tube shaking device, a culture dish opening device, a culture dish pushing device, a culture dish clamping device, a scribing device, a test tube tray, a culture dish holding container, a culture dish recycling container, a bar code scanner, and an infrared sterilizer. The scribing manipulator drives an inoculation loop on the scribing device to insert into the infrared sterilizer for disinfection. After disinfection, the scribing manipulator moves to insert the inoculation loop into the test tube clamped by the test tube opening clamping electric cylinder to dip the sample. The inoculation loop dipped with the sample moves back to the culture dish with the lid removed for a first scribing process. After the first scribing is completed, the inoculation loop rotation electric cylinder drives the scribing device to rotate so that the second inoculation loop on the scribing device is perpendicular downward, and the foregoing operations of disinfection, sample dipping, and scribing are repeated to complete the second scribing process. After the second scribing is completed, on the scribing device, and Chinese Patent CN205115449U discloses a fully automatic microbial sample processing device, both of which use automated equipment to achieve steps such as disinfection, labeling, lid opening, and classification, aiming to replace manual scribing operations and improve work efficiency.

A flipping component 11 is arranged on the top of the second linear slide rail 10. A culture dish 12 is inserted into the top of the flipping component 11. A homogenizing component 8 is fixedly installed on the top of the test bench 1. The homogenizing component 8 includes a vortex shaker 81. The vortex shaker 81 is fixedly installed on the top of the test bench 1. The output shaft of the vortex shaker 81 is fixedly installed with a chassis 82. Three sample conical flasks 83 are inserted into the top of the chassis 82. The vortex shaker 81 is used to drive the chassis 82 to vibrate. At the same time, three sample conical flasks 83 can be installed on the chassis 82. Culture medium and sample powder are placed in the sample conical flasks 83 and are mixed evenly by the vortex shaker 81. The flipping component 11 includes a second motor bracket 111. The second motor bracket 111 is fixedly installed on the top of the slider of the second linear slide rail 10. A second servo motor 112 is fixedly installed inside the second motor bracket 111. The output end of the second servo motor 112 is coaxially connected to a second transmission shaft rod 113. A tray 114 is fixedly installed at one end of the second transmission shaft rod 113 away from the second servo motor 112. Three placement sockets 114 are fixedly installed on the top of the tray 114. The shapes of the three placement sockets 114 are all circular, and a culture dish 12 is inserted into each of the three placement sockets 114. The culture dish 12 is an agar culture dish. The three culture dishes 12 can cooperate with the samples in different sample conical flasks 83 for comparison tests. The inoculation loop 7 is used to dip different samples and inoculate them into each culture dish 12, and the growth situation of the bacterial colonies is observed.

[0038] The first driving assembly 2 includes a first motor base 21 which is fixedly installed on the top of the test bench 1. A first servo motor 22 is fixedly installed on the top of the first motor base 21. The output end of the first servo motor 22 is coaxially connected with a first transmission shaft rod 23. The steering mechanism 3 includes a box body 31 which is fixedly installed on the top of the test bench 1. A rotating shaft base 32 is fixedly installed inside the box body 31. A driven rotating rod 33 is movably installed inside the rotating shaft base 32. A bevel gear 34 is fixedly installed on the outside of the driven rotating rod 33. One end of the first transmission shaft rod 23 far from the first servo motor 22 penetrates and extends into the inside of the box body 31 and is fixedly connected with the bevel gear 34. The lifting assembly 4 includes a first electric push rod 40. One end of the driven rotating rod 33 far from the rotating shaft base 32 penetrates the top of the box body 31 and is fixedly connected with the bottom of the first electric push rod 40. The output end of the first electric push rod 40 is fixedly installed with a mounting plate 41. The second electric push rod 5 is horizontally fixedly installed inside the mounting plate 41. The first driving assembly 2 is used to change the directions of the second electric push rod 5, the mounting assembly 6 and the inoculation loop 7, so as to realize the processes of sample dipping and inoculation. First, the first electric push rod 40 contracts to lower the second electric push rod 5, the mounting assembly 6 and the inoculation loop 7. After the lowered inoculation loop 7 contacts the sample inside the sample conical flask 83. Subsequently, the first electric push rod 40 rises. The first servo motor 22 drives the first transmission shaft rod 23 and the bevel gear 34 to rotate. When the bevel gear 34 rotates, the driven rotating rod 33 drives the first electric push rod 40 and the top connecting components to rotate, so that the inoculation loop 7 moves above the culture dish 12. Finally, the first electric push rod 40 descends to make the inoculation loop 7 contact the culture dish 12 for scribing to complete the inoculation;

[0039] It should be noted that in order to inoculate multiple samples, when the inoculation loop 7 is above the homogenizing assembly 8, the position between the inoculation loop 7 and the three sample conical flasks 83 can be adjusted by the expansion and contraction of the second electric push rod 5. Subsequently, after the inoculation loop 7 is above the culture dish 12, the inoculation loop 7 is also scribed and inoculated with the three culture dishes 12 by the expansion and contraction of the second electric push rod 5.

[0040] The installation component 6 includes a plate body 61. The plate body 61 is fixedly connected to the telescopic end of the second electric push rod 5. An annular groove 62 is formed inside the plate body 61. A threaded pipe 63 is fixedly installed on the inner wall of the annular groove 62. A threaded rod 64 is threadedly installed inside the threaded pipe 63. One end of the threaded rod 64 close to the annular groove 62 is movably connected to a bearing seat 65. A clamping plate 66 is fixedly installed on the outer wall of the bearing seat 65. A cap 14 is fixedly installed at the bottom of the plate body 61. The inoculation loop 7 is inserted into the annular groove 62. The clamping plate 66 is in a "C" shape. The inner wall of the clamping plate 66 fits with the inoculation loop 7. The plate body 61 is used to install the inoculation loop 7. First, insert the inoculation loop 7 into the annular groove 62. At the same time, rotate the threaded rod 64 to rotate and displace inside the threaded pipe 63. While the threaded rod 64 is displacing, it will push the bearing seat 65 and the clamping plate 66 to move. The shape of the clamping plate 66 can well fit with the inoculation loop 7 and cooperate with the annular groove 62 for clamping and fixing;

[0041] In addition, in order to meet the test requirements for multiple specimens, an alcohol disinfection lamp 13 is installed on the top of the test bench 1. When disinfection is required, the first driving component 2 rotates and adjusts the inoculation loop 7 to the direction of the specimen conical flask 83. At the same time, the second electric push rod 5 contracts so that the inoculation loop 7 is located above the alcohol disinfection lamp 13. At the same time, the first electric push rod 40 contracts so that the outer flame of the inoculation loop 7 is subjected to high-temperature disinfection to ensure the inactivation of the current microbial flora on the inoculation loop 7. Then it can be used to dip other specimens;

[0042] It should be noted that the alcohol disinfection lamp 13 is located below the cap 14. After inoculating the three culture dishes 12, the above disinfection method is adopted. Then the second electric push rod 5 continues to contract to move the cap 14 to the alcohol disinfection lamp 13, and the alcohol disinfection lamp 13 is blocked from the air by covering the alcohol disinfection lamp 13 with the cap 14 to ensure safety.

[0043] A controller 15 is fixedly installed on the side wall of the test bench 1. The first driving component 2, the lifting component 4, the second electric push rod 5, the first linear slide rail 9, the second linear slide rail 10 and the flipping component 11 are all electrically connected to the controller 15. The controller 15 is used for manually operating the start and stop of the electrically connected devices or for single-chip microcomputer automatic control to meet the needs of automatic tests;

[0044] In addition, due to different scribing methods, the test results obtained may also be different. To detect the survival habits of different microorganisms, methods such as segmented scribing, plate scribing, and zoned scribing can be used. Therefore, during the detection, a sample is first picked up by the inoculation loop 7 and simultaneously inoculated onto three culture dishes 12. The first linear slide rail 9 and the second linear slide rail 10 can drive the flipping assembly 11 and the culture dish 12 to move longitudinally and horizontally respectively, so that the inoculation loop 7 and the culture dish 12 move in opposite directions to complete the scribing operations on points and lines. The second servo motor 112 can drive the second transmission shaft rod 113 to rotate, so that the tray 114 and the culture dish 12 rotate, thereby achieving the effects of scribing on the surface and in zones, simulating various scribing techniques, and significantly improving the inoculation efficiency and increasing variables.

[0045] During use, the staff first lights the alcohol disinfection lamp 13. After determining whether to inoculate one sample or multiple samples according to the sample direction, the sample is added to the sample conical flask 83 and then shaken evenly by the vortex shaker 81. The controller 15 is used to control the first electric push rod 40 to descend so that the inoculation loop 7 contacts and picks up the culture solution inside the sample conical flask 83. At the same time, the second electric push rod 5 drives the inoculation loop 7 to rise again. The first drive assembly 2 drives components such as the lifting assembly 4 and the mounting assembly 6 to turn, so that the inoculation loop 7 moves above the culture dish 12. The expansion and contraction of the second electric push rod 5 can move the inoculation loop 7 above different culture dishes 12. Then the lifting assembly 4 contracts again so that the inoculation loop 7 contacts the culture dish 12. The first linear slide rail 9 and the second linear slide rail 10 can drive the culture dish 2 to move longitudinally and vertically, so that the inoculation loop 7 can scribe in the form of points and lines on the contact surface of the culture dish 12. The flipping assembly 11 can drive the culture dish 12 to rotate, thereby expanding the contact area to achieve the scribing effects of zoning and surface scribing. Finally, the inoculation loop 7 is disinfected by the alcohol disinfection lamp 13 to complete the inoculation. The staff only needs to collect the inoculated culture dishes 12.
