Therefore, the above terms should not be understood as limiting the present invention.

[0050] Implementation 1

[0051] like Figure 1-11 As shown in the figure, this automated microbial detection system can realize automatic bottle separation, bottle loading, cultivation, detection, bottle unloading and other actions, reduce manual intervention, and increase the accuracy of the test results, including:

[0052] The rack 500 is used to install each module, and also includes a shell 600 outside the rack, and the shell 600 has an entry 601 corresponding to the loading module 100;

[0053] The loading module 100 is used to input the culture bottle and perform weighing detection, code scanning detection and flipping respectively, and dock the culture bottle with the bottle pushing module 240 by flipping;

[0054] In this embodiment, if Figure 2 As shown, the loading module 100 includes a conveyor belt module 103, a loading turntable 104, a weighing disk 106, a barcode scanning gun 117, and a bottle turning clamp 114; the conveyor belt module is provided with a loading area for placing culture bottles, and the conveyor belt module can transport the culture bottles to one of the positioning notches of the loading turntable 104. The loading turntable 104 is provided with at least four positioning notches along the circumferential direction, and the loading turntable 104 can rotate to drive the culture bottles to circulate along the bottle loading position, the weighing position, the barcode scanning position and the bottle turning position. The barcode scanning gun 117 is used to scan the QR code on the culture bottle, and the bottle turning clamp 114 can clamp the culture bottle on the bottle turning position and drive the culture bottle to turn over by the clamp driver, so that it turns 180° so that it can be clamped by the bottle pushing module 240.

[0055] Specifically, the loading module 100 uses a conveyor belt module 103 to transport culture bottles, the transport speed is adjustable, and a bottle pushing module 240 is installed at the transport end.

[0056] Among them, the loading turntable 104 has four bottle positions, namely the bottle loading position, weighing position, code scanning position, and bottle turning position. The bottle position sensor 122 detects whether there is a culture bottle at the upper bottle position to determine the start and stop of the conveyor belt module 103. The weighing plate 106 at the weighing position has a weighing sensor to detect the weight of the culture bottle and judge whether the weight of the culture bottle is qualified (mainly to judge whether the weight corresponds to the weight data scanned by the QR code, if not, it is unqualified). The code scanning position is to scan and identify the QR code of the bottle body. This bottle position has a bottle body rotation function to ensure that the code scanning gun 117 can completely capture the QR code of the bottle body. The weighing and code scanning information is analyzed and interpreted by the system, and unqualified culture bottles will be discarded.

[0057] Among them, after the culture bottle reaches the bottle turning position, the clamping claws clamp the culture bottle and turn the bottle, turn the bottle to the designated position to wait for the bottle pushing claws to clamp it, and the bottle turning action is precisely controlled by the bottle turning motor 125. After the bottle pushing claws clamp the culture bottle, they push it to the upper bottle position to wait for the upper bottle claws 237 to clamp it. When the bottle lowering function is executed after the subsequent culture detection is completed, the upper bottle claws 237 take out the culture bottle from the culture rack and move it to the upper bottle position (the upper bottle and lower bottle positions are the same position), the bottle pushing claws clamp the culture bottle, the upper bottle claws 237 are released, and the bottle pushing claws clamp the culture bottle and retreat to the top of the guide groove 249. According to the negative or positive culture bottle determined by the system, it is placed in different guide grooves 249, and the culture bottle slides from the guide groove 249 to different recycling buckets.

[0058] Preferably, two recycling barrels can be provided, an unqualified recycling barrel 501 for collecting unqualified culture bottles and negative culture bottles, and a qualified recycling barrel 502 for collecting positive culture bottles. Of course, three recycling barrels can also be provided, with an additional recycling barrel to separately recycle unqualified culture bottles and negative culture bottles.

[0059] The bottle pushing module 240 is used to receive the flipped culture bottles and the culture bottles taken out by the bottle loading module 200. The culture bottles that have passed the code scanning test are pushed to the corresponding positions for the bottle loading module 200 to pick up. The culture bottles that have not passed the code scanning test and the culture bottles with negative culture results are placed in the unqualified area, and the culture bottles with positive culture results are placed in the qualified area.

[0060] In this embodiment, the bottle pushing module 240 includes a bottle pushing clamp for gripping the flipped culture bottle and a bottle pushing module 253 for driving the bottle pushing clamp to approach and move away from the upper bottle module 200. Preferably, the bottle pushing module 240 also includes a guide groove 249 for guiding the culture bottle to different areas.

[0061] The bottle loading module 200 is arranged beside the culture module 300 and the loading module 100, and is used to clamp the flipped culture bottle and flip it again, so that the culture bottle can be inserted into the corresponding bottle sleeve assembly 320 on the culture module 300 to complete the bottle loading action; and the bottle loading module 200 can drive the culture bottle to move along the XZ axis;

[0062] In this embodiment, the upper bottle module 200 includes an upper bottle clamp 237, a rotation driver for driving the upper bottle clamp 237 to rotate so that the culture bottle is flipped again, an X-axis slider module 232 for driving the rotation driver and the upper bottle clamp 237 to move back and forth along the X-axis, and a Z-axis slider module for driving the clamp assembly 230 to move back and forth along the Z-axis. The upper bottle clamp 237, the rotation driver and the X-axis slider module 232 constitute the clamp assembly 230.

[0063] Specifically, the bottle loading module 200 is composed of a plurality of slider modules and a clamping claw assembly 230. The Z-axis slider module 216 controls the movement in the Z-axis direction. The Z-axis slider module 216 is installed between the right vertical plate 213 and the left vertical plate 214, with the support plate 215 connected on both sides and the module cover plate assembled on the top. When this structure is assembled, the support plate 215, the right vertical plate 213 and the bottle loading module bottom plate 220 are vertically installed to ensure that the bottom and top bottles are in the same Z-axis direction when loading bottles.

[0064] Among them, the X-axis slider module 232 controls the movement in the X-axis direction. The X-axis slider module 232 is installed on the clamp assembly base plate 231. The X-axis slider module 232 drives the clamp mounting base plate to move. During the movement, the rotating swing block 234 (rotational driver) can rotate the second clamp motor 90° according to the guide groove of the clamp assembly base plate 231. This movement structure can rotate the culture bottle 90° from the upper bottle clamping state position point and insert the culture bottle into the bottle sleeve 321, and can also extract the culture bottle in the bottle sleeve 321 and rotate it 90° to the discard bottle position point and the defective bottle placement position point. The second clamp motor controls the upper bottle clamp 237 to clamp the bottom of the culture bottle and cooperate with the bottle turning clamp 114 to complete the bottle loading action.

[0065] The culture module 300 is provided with multiple layers of trays 307 with concave and convex surfaces, and multiple bottle sleeve assemblies 320 are evenly spaced along the circumferential direction on each layer of the tray 307. Each bottle sleeve assembly 320 is connected to the central shaft 308 of the culture module 300, and the central shaft 308 can drive all the bottle sleeve assemblies 320 to rotate simultaneously, so that the bottle sleeve assemblies 320 will swing up and down when passing through the concave and convex surfaces on the tray 307, thereby promoting the growth of microorganisms in the culture bottle;

[0066] In this embodiment, the culture module 300 includes a central rotating shaft 308, a culture rotating motor 301 for driving the central rotating shaft 308 to rotate, a bottle sleeve fixing member 311 arranged on the outer ring of the central rotating shaft 308, a multi-layer tray 307 with a concave and convex surface, and a rotating barrel support plate 305 arranged around the tray 307 for supporting the tray 307. The bottle sleeve fixing member 311 is provided with a plurality of bottle sleeve assemblies 320 along the circumferential direction, and each bottle sleeve assembly 320 is rotatably connected to the bottle sleeve fixing member 311. The central rotating shaft 308, the tray 307, the bottle sleeve assembly 320, etc. constitute a structure similar to a rotating barrel, and the rotating barrel hereinafter refers to these structures.

[0067] Specifically, the culture module 300 uses the central shaft 308 to drive the bottle sleeve 321 to make a circular motion. When the bottle sleeve 321 moves on the tray 307, it passes through the concave and convex surface of the tray 307, causing the bottle sleeve 321 to swing up and down at an angle with the top of the bottle sleeve 321 as the origin. During this process, the liquid inside the culture bottle shakes regularly, promoting the growth of microorganisms in the culture bottle.

[0068] The bottle sleeve 321 of the bottle sleeve assembly 320 is connected to the bottle sleeve fixing member 311 by a shaft and a bearing, so that the bottle sleeve 321 makes a circular motion at a certain angle with the shaft as the center when the tray 307 moves up and down. The tray 307 is designed to have a concave and convex inclined surface, and the convex inclined surface is concave at a certain angle from the outer circle to the center of the circle, and the concave surface is a plane, so as to ensure that the culture bottle is in a state where the bottom of the bottle is lifted up at a certain angle when it is on the convex surface, and the culture bottle is in a horizontal state when it is on the concave surface. When the culture bottle rotates with the axis, it passes through the concave and convex surface to form an ups and downs wave, so as to achieve the effect of shaking the culture.

[0069] Preferably, a plunger 322 (an embodiment of a fixing member) is installed inside the bottle sleeve 321. The marble on the top of the plunger 322 effectively clamps the head of the culture bottle to prevent the culture bottle from escaping from the bottle sleeve 321 during rotation. The installation position of the plunger 322 can be adjusted according to the diameter of the head of the culture bottle to solve the problem of different sizes of culture bottles. This circular culture rack has high space utilization and stable structure, which increases the number of culture bottles and the stability of the culture process.

[0070] Preferably, another type of fixing member may be a spring sheet, which is used to fix the culture bottle. Of course, other structures that use interference fit to achieve fixation are also acceptable, and the present invention does not limit this.

[0071] The detection module 400 is disposed on one side of the culture module 300 and is used to perform growth detection on the culture bottle in the bottle sleeve assembly 320 .

[0072] In this embodiment, the detection module 400 includes one or more groups of cameras 407 , a detection slider module 403 for driving the camera 407 to move back and forth along the Z axis, and a light source 406 for supplementing light for the camera 407 .

[0073] Specifically, the detection module 400 is mainly composed of three groups of cameras 407, a light source 406 and a detection slider module 403. The brightness of the light source 406 is adjustable. During detection, the brightness of the three groups of light sources 406 is ensured to be consistent. The camera 407 is used to capture the true color of the culture bottle. The detection slider module 403 drives the camera 407 to different positions to detect culture bottles of different heights. With the rotation of the rotating barrel, all culture bottles can be detected. The simultaneous detection of the three groups of cameras 407 increases the detection speed in terms of efficiency, saves equipment operation space in terms of structure, and the simultaneous operation of the three groups of cameras 407 greatly reduces the control cost and increases the consistency of the detection results. Among them, the specific algorithm of the detection is a prior art and will not be repeated here.

[0074] The alarm module is used to issue corresponding reminders according to the detection results of the detection module 400.

[0075] In this embodiment, the alarm module is not limited to providing reminders, but can also generate a detection report.
