Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See attached document Figures 1-5This embodiment provides an automatic sample bottle cleaning system, including: a feeding and conveying mechanism 1, a sample bottle rotating frame 2, an ultrasonic cleaning device 3, a rinsing device 4, an air drying device 5, and a bottle-dispensing mechanism 6. The sample bottle rotating frame 2 includes a rotatable main shaft 21, on which three sets of sample bottle racks 22 are fixed. Each set of sample bottle racks 22 includes multiple sample bottle racks 22 distributed around the outer periphery of the main shaft 21. Multiple sample bottles 100 are slidably arranged on the sample bottle racks 22. The ultrasonic cleaning device 3, the rinsing device 4, and the air drying device 5 are respectively arranged in a one-to-one correspondence with the three sets of sample bottle racks 22. Specifically, the ultrasonic cleaning device 3 is used to perform ultrasonic cleaning on the sample bottles 100 of the first set of sample bottle racks 22, the rinsing device 4 is used to clean the sample bottles 100 of the second set of sample bottle racks 22 again, and the air drying device 5 is used to air dry the sample bottles 100 of the third set of sample bottle racks 22. A connecting passage 200 is provided between two adjacent sets of sample bottle racks 22. The connecting passage 200 and the feeding conveyor 1 are distributed in a straight line. The bottle-pulling mechanism 6 is used to push the sample bottle 100 between the sample bottle rack 22 and the connecting passage 200 and to push the sample bottle 100 in the sample bottle rack 22 to be unloaded. Specifically, the bottle-pulling mechanism 6 pushes the sample bottle 100 that has been ultrasonically cleaned in the first set of sample bottle racks 22 to the second set of sample bottle racks 22 through the connecting passage 200. The bottle-pulling mechanism 6 pushes the sample bottle 100 that has been rinsed in the second set of sample bottle racks 22 to the third set of sample bottle racks 22 through the connecting passage 200. The bottle-pulling mechanism 6 pushes the sample bottle 100 that has been air-dried in the third set of sample bottle racks 22 onto the unloading conveyor belt. The discharge end of the feeding conveyor 1 is connected to the feed end of the sample bottle rotating frame 2. When the sample bottle 100 reaches the discharge end of the feeding conveyor 1, it is pushed into the first set of sample bottle racks 22 by the bottle-pushing mechanism 6 or other auxiliary mechanisms. Specifically, the number of sample bottle racks 22 in each set of sample bottle racks 22 is 6.

[0031] The working process of this embodiment is as follows: Sample bottles 100 on the feeding conveyor 1 reach the discharge end and are then pushed into the sample bottle rack 22. After the sample bottle rack 22 is filled with sample bottles 100, the main shaft 21 rotates, and an empty sample bottle rack 22 rotates to the discharge end of the feeding conveyor 1. Then, sample bottles 100 are pushed into the sample bottle rack 22. The above steps are repeated until the first set of sample bottle racks 22 is completely filled with sample bottles 100. The main shaft 21 rotates continuously, and the sample bottle rack 22 filled with sample bottles 100 returns to the discharge end of the feeding conveyor 1 after rotating one revolution. During this process, the sample bottle rack 22 will undergo ultrasonic cleaning by the ultrasonic cleaning device 3. That is, when the sample bottle rack 22 filled with sample bottles 100 returns to the discharge end of the feeding conveyor 1 after rotating one revolution, the sample bottles 100 in the sample bottle rack 22 have completed ultrasonic cleaning.

[0032] Then refer to the appendix. Figure 11The bottle-dispensing mechanism 6 pushes the ultrasonically cleaned sample bottles 100 through the connecting passage 200 into the second set of sample bottle racks 22. The empty sample bottle racks 22 in the first set of sample bottle racks 22 are filled by the feeding conveyor mechanism 1. The main shaft 21 rotates, and an empty sample bottle rack 22 in the second set of sample bottle racks 22 rotates to the connecting passage 200. The bottle-dispensing mechanism 6 pushes the ultrasonically cleaned sample bottles 100 through the connecting passage 200 into the second set of sample bottle racks 22. The empty sample bottle racks 22 in the first set of sample bottle racks 22 are filled by the feeding conveyor mechanism 1. The above steps are repeated until the second set of sample bottle racks 22 is completely filled with sample bottles 100. As the main shaft 21 rotates continuously, the sample bottle rack 22 located at the connecting passage 200, which contains sample bottles 100, returns to the connecting passage 200 after rotating one revolution. During this process, the sample bottle rack 22 will be cleaned again by the rinsing device 4. That is, when the sample bottle rack 22, which is full of sample bottles 100 at the connecting passage 200, returns to the connecting passage 200 after rotating one revolution, the sample bottles 100 in the sample bottle rack 22 have been rinsed.

[0033] Then, the bottle-dispensing mechanism 6 pushes the rinsed sample bottles 100 through the connecting passage 200 into the third set of sample bottle racks 22. The empty sample bottle racks 22 in the second set of sample bottle racks 22 are filled by the first set of sample bottle racks 22, and the empty sample bottle racks 22 in the first set of sample bottle racks 22 are filled by the feeding conveying mechanism 1. The main shaft 21 rotates, and one empty sample bottle rack 22 in the third set of sample bottle racks 22 rotates to the connecting passage 200. The bottle-dispensing mechanism 6 pushes the rinsed sample bottles 100 through the connecting passage 200 into the third set of sample bottle racks 22. The empty sample bottle racks 22 in the second set of sample bottle racks 22 are filled by the first set of sample bottle racks 22, and the empty sample bottle racks 22 in the first set of sample bottle racks 22 are filled by the feeding conveying mechanism 1. The above steps are repeated until the third set of sample bottle racks 22 is completely filled with sample bottles 100. As the main shaft 21 rotates continuously, the sample bottle rack 22 in the third set of sample bottle racks 22, which is located at the connecting passage 200 and contains sample bottles 100, returns to the connecting passage 200 after rotating once. During this process, the sample bottle rack 22 will be dried by the air drying device 5. That is, when the sample bottle rack 22, which is full of sample bottles 100 at the connecting passage 200, returns to the connecting passage 200 after rotating once, the sample bottles 100 in the sample bottle rack 22 have been dried.

[0034] Then, the bottle-dispensing mechanism 6 pushes the dried sample bottles 100 onto the unloading conveyor belt. The hollow sample bottle racks 22 in the third group are filled by the second group of sample bottle racks 22, the hollow sample bottle racks 22 in the second group are filled by the first group of sample bottle racks 22, and the hollow sample bottle racks 22 in the first group are filled by the feeding conveyor mechanism 1. The main shaft 21 rotates continuously. When the sample bottle racks 22 pass through the connecting passage 200, the bottle-dispensing mechanism 6 pushes the dried sample bottles 100 onto the unloading conveyor belt. The hollow sample bottle racks 22 in the third group are filled by the second group of sample bottle racks 22, the hollow sample bottle racks 22 in the second group are filled by the first group of sample bottle racks 22, and the hollow sample bottle racks 22 in the first group are filled by the feeding conveyor mechanism 1. At this point, with each rotation of the main shaft 21, the bottle-dispensing mechanism 6 unloads a sample bottle 100 from one sample bottle rack 22, and all three sample bottle racks 22 are filled once. The ultrasonic cleaning device 3, rinsing device 4, and drying device 5 simultaneously perform ultrasonic cleaning, rinsing, and drying on the sample bottles 100 in the three sample bottle racks 22. This utility model has a compact overall structure and ingenious design, capable of simultaneously performing ultrasonic cleaning, rinsing, and drying on the sample bottles 100 in the three sample bottle racks 22. After each ultrasonic cleaning, rinsing, and drying cycle, it can automatically load and unload the sample bottles and automatically transfer the sample bottles 100 between the three processes.

[0035] As another embodiment of the utility model: refer to the appendix Figure 6 The feeding conveyor 1 has multiple feeding channels 9 at its feeding end for conveying sample bottles 100 of different specifications. Within each set of sample bottle racks 22, the specifications of the racks differ, allowing for the loading of sample bottles 100 of varying sizes. On the sample bottle rotating frame 2, sample bottle racks 22 of the same specifications are arranged in a straight line parallel to the main shaft 21, facilitating the transfer of sample bottles 100 between the three sets of racks 22. Specifically, the feeding conveyor 1 and the feeding channels 9 are perpendicularly distributed. This structural design enables the cleaning system to simultaneously clean sample bottles 100 of different diameters and heights without requiring manual adjustment of the sample bottle racks 22, thus improving the adaptability of the cleaning system and effectively saving investment.

[0036] In another embodiment of the utility model: the sample bottle rack 22 is provided with a material passage 221 for the sample bottle 100 to move along the length direction of the main shaft 21. The bottom of the sample bottle 100 slides along the end of the material passage 221 near the main shaft 21. The end of the material passage 221 away from the main shaft 21 is provided with a notch 222, the width of which is smaller than the diameter of the bottle mouth of the sample bottle 100. This is to prevent the sample bottle 100 from slipping off the notch 222. Furthermore, the notch 222 is provided to avoid interference between the bottle-pushing mechanism 6 and the sample bottle rack 22 when the bottle is pushed.

[0037] Specifically, the bottle-dispensing mechanism 6 is located above the connecting passageway 200.

[0038] One embodiment of the bottle-dispensing mechanism 6: The bottle-dispensing mechanism 6 includes: a bottle-dispensing block 61, a lifting assembly 62, and a translation assembly 63. The translation assembly 63 is connected to the lifting assembly 62, and the lifting assembly 62 is connected to the bottle-dispensing block 61. The bottle-dispensing block 61 is located above the connecting passage 200. The lifting assembly 62 is used to drive the bottle-dispensing block 61 to rise and fall. During bottle dispensing, it descends to the side of the sample bottle 100 to facilitate the translation assembly 63 in pushing the sample bottle 100 for transfer or unloading between the three processes. When the main shaft 21 rotates, it rises above the sample bottle 100 to avoid interference with the sample bottle rack 22. Specifically, the translation assembly 63 includes: a guide rail, a slider, a lead screw, and a servo motor. The servo motor drives the lead screw to rotate. The lead screw is threadedly connected to the slider, which slides along the guide rail. The lifting assembly 62 is an electric cylinder, and the slider is fixed to the bottle-dispensing block 61 by the electric cylinder.

[0039] One embodiment of the ultrasonic cleaning device 3: Refer to the attached document. Figure 7 The ultrasonic cleaning device 3 includes a cleaning frame, an inlet pipe 32, a drain pipe 33, and an overflow pipe 34. The cleaning frame includes a cleaning tank 31 with an overall open top. The cleaning tank 31 is equipped with an ultrasonic source 35 and a first heater 36. The cleaning tank 31 includes a bottom plate and a first side plate, a second side plate, a third side plate, and a fourth side plate connected end to end. The bottom of the first side plate and the third side plate extend downward to form two bottom support plates. The two bottom support plates and the bottom plate together form a pipe receiving cavity for accommodating the drain pipe 33. The two ends of the drain pipe 33 are an inlet and an outlet, respectively. The inlet and outlet penetrate the bottom plate, and the outlet extends out of the pipe receiving cavity. The inlet pipe 32 and the overflow pipe 34 are both installed on the top of the fourth side plate. The top of the third side plate is equipped with an observation plate. The cleaning tank 31 is also equipped with a liquid level sensor and a temperature sensor, which are respectively installed on the fourth side plate. When the switch is turned on, water flows from the inlet pipe 32 into the cleaning tank 31. When the level sensor detects sufficient water, the switch closes to stop adding water. The first heater 36 begins heating the water. When the temperature sensor detects that the water temperature in the tank has reached the set temperature, the ultrasonic source 35 starts working and cleans the sample bottles 100 in the sample bottle rack 22 that have passed through the cleaning tank 31. If there is fluctuation in the water during the cleaning process, it can be discharged through the overflow pipe 34. After cleaning, the wastewater is discharged through the drain pipe 33. This invention uses ultrasonic bottom radiation cleaning, ensuring ultrasonic waves reach all areas without blind spots, resulting in excellent cleaning performance.

[0040] One embodiment of the rinsing device 4: Refer to the attached document. Figure 10The rinsing device 4 includes a fixed plate 41, a base, and a cleaning nozzle. A telescopic mechanism 42 is fixed to the base and drives the fixed plate 41 to rise and fall. A rotary joint is fixed to the fixed plate 41, and a brush 43 is detachably connected to the rotary joint. A water inlet 44 is provided at the end of the rotary joint away from the brush 43, and the water inlet 44 is connected to the nozzle at the end of the brush 43 away from the rotary joint. The cleaning nozzle is located above the brush 43 and is connected to a water supply pipe. The telescopic mechanism 42 pushes the brush 43 upward into the sample bottle 100. The rotary joint drives the brush 43 to rotate, starting to clean the sample bottle 100. Water from the water inlet 44 passes through the rotary joint and the brush 43 and is sprayed out from the nozzle to assist the brush 43 in cleaning. Since the bottle opening of the sample bottle 100 is facing downward, the wastewater and dirt washed out during the cleaning process flow out of the bottle opening along the bottle body, resulting in a high degree of cleanliness inside the bottle and a good cleaning effect. At the same time, the cleaning nozzle sprays water onto the outside of the sample bottle 100.

[0041] One embodiment of the air-drying device 5: Refer to the attached document. Figure 8 The air drying device 5 includes a fan 51, a second heater 52, and a diversion pipe 53. The fan 51 is connected to the second heater 52 through a pipe. The air outlet of the second heater 52 is connected to the diversion pipe 53. The diversion pipe 53 is connected to a lifting drying assembly 54 and an air knife drying assembly 55. The lifting drying assembly 54 includes multiple lifting air outlet pipes 541. The air outlet pipes 541 move upward and extend into the sample bottle 100 to blow hot air. The air knife drying assembly 55 includes multiple sets of air knife nozzles 551 set above the air outlet pipes 541. The multiple sets of air knife nozzles 551 are located on both sides of the sample bottle 100. The multiple sets of air knife nozzles 551 blow hot air to the outside of the sample bottle 100. The air knife nozzles 551 and the air outlet pipes 541 dry the sample bottles 100 in two sample bottle racks 22 of the third set of sample bottle racks 22, respectively. This invention achieves simultaneous drying of multiple sample bottles 100 by using a lifting drying assembly 54 and an air knife drying assembly 55 to dry the sample bottles 100 in two steps. Specifically, one sample bottle rack 22 is rotated above the air outlet pipe 541, which rises and extends into the sample bottle 100 of the rack to dry its interior. Then, the rack 22 rotates with the main shaft 21 to the air knife drying assembly 55, where the air knife nozzle 551 dries the exterior of the sample bottle 100. Simultaneously, another sample bottle rack 22 rotates above the air outlet pipe 541, which rises and extends into the sample bottle 100 of the rack to dry its interior. This invention dries sample bottles 100 in two steps by setting up a lifting drying component 54 and an air knife drying component 55, thereby achieving simultaneous drying of multiple sample bottles 100 and improving the drying efficiency of sample bottles 100.

[0042] One embodiment of sample bottle rack 22: Refer to the attached document. Figure 9The sample bottle holder 22 includes limiting rods 223 and a support plate 224. The bottom of the sample bottle 100 slides along the support plate 224. At least two limiting rods 223 are located on both sides of the sample bottle 100, and two limiting rods 223 are located above the bottle opening of the sample bottle 100. The distance between the two limiting rods 223 is less than the diameter of the bottle opening of the sample bottle 100. The limiting rods 223 and the support plate 224 form a material passage 221. The limiting rods 223 restrict the sample bottle 100 within the material passage 221, so that the sample bottle 100 can only slide along the support plate 224. The two limiting rods 223 above the bottle opening form notches 222 for subsequent bottle pushing. In this structure, the contact area between the limiting rods 223 and the sample bottle 100 is small.

[0043] As another embodiment of this utility model: refer to the appendix Figure 6 The feeding channel 9 is equipped with a rotating conveyor belt 91. A transition conveying roller 92 is provided in the gap between the conveyor belt 91 and the feeding conveying mechanism 1. The conveyor belt 91 is connected to the feeding conveying mechanism 1 via the transition conveying roller 92. The conveyor belt 91 transmits power to the transition conveying roller 92 through a gear set to drive the transition conveying roller 92 to rotate. The conveyor belt 91 is equipped with a gantry frame 93. The gantry frames 93 on the conveyor belt 91 have different specifications to allow sample bottles 100 of different specifications to pass through. The two ends of the gantry frame 93 are respectively equipped with a stop block 94. The stop block 94 is connected to a cylinder 95. The cylinder 95 is used to drive the stop block 94 to extend or retract to stop or allow the sample bottle 100 to move forward. The transition conveyor roller 92 serves as a transition, filling the gap between the vertical connection between the conveyor belt 91 and the feeding conveyor mechanism 1, increasing the friction at the bottom of the sample bottle 100, thereby preventing the sample bottle 100 from getting stuck or tipping over during the transition from the conveyor belt 91 to the feeding conveyor mechanism 1.

[0044] As another embodiment of the present invention: This embodiment also includes a pushing mechanism disposed between the feeding conveying mechanism 1 and the sample bottle rotating frame 2. The pushing mechanism is used to push the sample bottle 100 of the feeding conveying mechanism 1 into the first set of sample bottle frames 22.

[0045] As another embodiment of this utility model: refer to the appendix Figure 1 This embodiment also includes a housing 7 and multiple partitions, which divide the housing 7 into multiple isolation chambers. The ultrasonic cleaning device 3, the rinsing device 4, and the drying device 5 are each located in one isolation chamber. An exhaust pipe 300 is provided at the upper end of the housing 7, and the exhaust pipe 300 is connected to the isolation chamber. This embodiment also includes a control cabinet 8, which is located on the side of the ultrasonic cleaning device 3 near the feed channel 9. Specifically, the control cabinet 8 is also located in one isolation chamber.

[0046] In another embodiment of this utility model: the main shaft 21 is connected to the servo motor via a coupling, a reducer, and a bracket is fixed between the main shaft 21 and the sample bottle rack 22. There are three sets of brackets, each corresponding to one of the three sets of sample bottle racks 22. Each bracket has six sample bottle racks 22. The bracket corresponding to the third set of sample bottle racks 22 has six positioning pin holes, evenly distributed on the bracket. Inserting a positioning rod into the positioning pin holes effectively ensures more accurate repeated rotation positioning and reduces repeated positioning errors. This utility model offers strong bottle applicability; by changing the sample bottle rack 22, it can accommodate various sizes of sample bottles 100.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
