DETAILED DESCRIPTION

[0032] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0033] like Figure 1-Figure 8 As shown, a PCR8 tube rack automatic cleaning device includes a base 1, a turntable assembly 2, a drive assembly 3, a transmission assembly 4 and a clamping assembly 5;

[0034] A cleaning space 11 is provided inside the base 1, the PCR8 tube rack 8 is placed in the cleaning space 11 for disinfection, the turntable assembly 2 is provided in the cleaning space 11, the transmission assembly 4 is connected to the clamping assembly 5, and the clamping assembly 5 is used to clamp the PCR8 tube rack 8;

[0035] The driving assembly 3 is used to drive the transmission assembly 4 to move, and the clamping assembly 5 moves clockwise to flip relative to the turntable assembly 2, so as to sterilize the PCR8 tube rack 8 in all directions; the clamping assembly 5 moves counterclockwise to rotate horizontally relative to the turntable assembly 2, so as to spin dry the PCR8 tube rack 8;

[0036] Clockwise rotation for flipping motion: the driving assembly 3 drives the rotating disc 41 to rotate, while the fixed disc 22 is fixed, so that the transmission assembly 4 installed on the rotating disc 41 rotates synchronously. When the rotating disc 41 starts to rotate, a rotating wheel 43 slides upward along the first inclined portion 61. The rotating wheel 43 slides to the top of the first inclined portion 61, and the transmission member 42 has completed a 0-90° flip. As the rotating disc 41 continues to rotate, the rotating wheel 43 enters the vertical portion 63 from the top of the first inclined portion 61. The rotating motion of the rotating disc 41 drives the other rotating wheel 43 to continue to flip. The rotating wheel 43 at the vertical part 63 is pulled by another rotating wheel 43 and enters the second inclined part 62 from the vertical part 63. When the rotating wheel 43 slides to the bottom of the vertical part 63 and enters the second inclined part 62, the transmission member 42 starts to flip 90-180 degrees, realizing the flip of the PCR8 tube rack 8 from 90 degrees to 180 degrees; reciprocatingly circulates between the bottom of the fixed disc 22 and the flip groove 6 to realize the reciprocating flipping of the PCR8 tube rack 8, and cooperates with the spraying system 71 installed on the top surface of the base 1 to comprehensively clean the PCR8 tube rack 8;

[0037] Horizontal circular motion in counterclockwise direction: since the top of the horizontal groove 231 is flush with the bottom of the fixed disc 22, the movement of the rotating wheel 43 from the fixed chassis to the horizontal groove 231 will be maintained on a relatively stable horizontal plane; the rotating wheel 43 continues to rotate under the driving force of the rotating disc 41, and performs circular motion at the bottom of the fixed disc 22. When the transmission assembly 4 moves to the second inclined portion 62, the one-way single plate restricts the rotating wheel 43 from entering the second inclined portion 62, so that the rotating wheel 43 enters the horizontal groove 231 flush with the bottom of the fixed disc and continues to perform circular motion, thereby realizing the flipping of the connecting rod frame. Centrifugal force will be generated through horizontal rotation, prompting the water in the PCR8 tube rack 8 to be thrown out, thereby achieving the effect of drying;

[0038] In summary, through multi-angle flipping movements, the present invention can ensure that the disinfectant fully contacts and penetrates into every detail of the PCR8 tube rack 8, thereby greatly shortening the disinfection time and improving the disinfection efficiency; through sufficient disinfection and spin-drying treatments, it can ensure that the PCR8 tube rack 8 will not affect the accuracy of the experimental results due to residual disinfectant in subsequent experiments. The entire disinfection process is completed by automated components such as the drive component 3, the transmission component 4 and the clamping component 5, without the need for manual intervention, which greatly improves the convenience and automation of operation.

[0039] In one embodiment, the turntable assembly 2 includes a fixed seat 21, a fixed disc 22 and a guide seat 23; the fixed seat 21 serves as the base 1 of the entire turntable assembly 2 and is installed in the cleaning space 11 to provide stable support for the turntable assembly 2 and ensure stability during the entire cleaning process. The fixed disc 22 is arranged on the top of the fixed seat 21 and has a cylindrical structural feature. The fixed disc 22 not only serves as a support platform for the flipping movement of the clamping assembly 5, but also cooperates with the guide seat 23 through the sliding groove on its side wall to form a flipping groove 6. The design of the guide seat 23 ensures that the clamping assembly 5 can move smoothly along a predetermined path during the flipping process. When passing through the flipping groove 6, the transmission assembly 4 drives the clamping assembly 5 to flip in the flipping groove 6, and the sliding groove is connected to the bottom of the fixed disc 22.

[0040] In one embodiment, the transmission assembly 4 includes a rotating disk 41 and a transmission member 42; the rotating disk 41 and the fixed disk 22 are coaxially rotatably connected, and the rotation of the rotating disk 41 drives the transmission member 42 to move; the rotating disk 41 is located at the outer periphery of the fixed disk 22, and the transmission member 42 is located between the fixed disk 22 and the rotating disk 41. The rotating disk 41 is provided with a mounting groove, and the transmission member 42 is installed in the mounting groove and extends to the outer periphery of the rotating disk 41. The driving assembly 3 drives the rotating disk 41 to rotate, while the fixed disk 22 is fixed, so that the transmission assembly 4 installed on the rotating disk 41 rotates synchronously and moves along the trajectory of the fixed disk 22.

[0041] In one embodiment, the transmission member 42 is provided with two rotating wheels 43, and the two rotating wheels 43 are installed at the two ends of the transmission member 42 away from the installation groove; the flip groove 6 is composed of a first inclined portion 61, a second inclined portion 62 and a vertical portion 63 to form an inverted Y shape, and moves in the same direction, and a rotating wheel 43 passes through the first inclined portion 61, the vertical portion 63, and the second inclined portion 62 in sequence; the first inclined portion 61 cooperates with the two rotating wheels 43 to complete the flipping of the clamping assembly 5 by 0-90°, and the second inclined portion 62 cooperates with the two rotating wheels 43 to complete the flipping of 90-180°;

[0042] When the rotating disc 41 starts to rotate, a rotating wheel 43 slides upward along the first inclined portion 61, and the rotating wheel 43 slides to the top of the first inclined portion 61. The transmission member 42 has completed the 0-90° flip. As the rotating disc 41 continues to rotate, the rotating wheel 43 enters the vertical portion 63 from the top of the first inclined portion 61. The rotating motion of the rotating disc 41 drives the other rotating wheel 43 to continue to make a circular motion, and the rotating wheel 43 located at the vertical portion 63 is pulled by the other rotating wheel 43 and enters the second inclined portion 62 from the vertical portion 63. When the rotating wheel 43 slides to the bottom of the vertical portion 63 and enters the second inclined portion 62, the transmission member 42 starts to flip 90-180°, realizing the flip of the PCR8 tube rack 8 from 90°-180°; reciprocatingly circulates between the bottom of the fixed turntable and the flip groove 6 to realize the reciprocating flip of the PCR8 tube rack 8, and cooperates with the spraying system 71 installed on the top surface of the base 1 to comprehensively clean the PCR8 tube rack 8;

[0043] In summary, through the cooperation of the inverted Y-shaped flip groove 6 and the two rotating wheels 43, the precise flipping control of the clamping assembly 5 in the range of 0-180° is achieved, ensuring the stability and accuracy during the cleaning process; through precise flipping control, it can be ensured that the PCR8 tube rack 8 is fully rinsed and soaked during the cleaning process, thereby enhancing the cleaning effect.

[0044] In one embodiment, the guide seat 23 is further provided with a horizontal groove 231, the top of which is flush with the bottom of the fixed disc 22; and further includes a one-way baffle, which is rotatably disposed on the guide seat 23 and located at the junction of the second inclined portion 62 and the horizontal groove 231;

[0045] Since the top of the horizontal groove 231 is flush with the bottom of the fixed disc 22, the movement of the rotating wheel 43 from the fixed chassis to the horizontal groove 231 will be maintained on a relatively stable horizontal plane; the rotating wheel 43 continues to rotate under the driving force of the rotating disc 41, and makes a circular motion at the bottom of the fixed disc 22. When the transmission assembly 4 moves to the second inclined portion 62, the existence of the one-way single plate restricts the rotating wheel 43 from entering the second inclined portion 62, so that the rotating wheel 43 enters the horizontal groove 231 flush with the bottom of the fixed disc and continues to make a circular motion, thereby realizing the flipping of the connecting rod frame. The horizontal rotation will generate centrifugal force, which prompts the water in the PCR8 tube rack 8 to be thrown out, thereby achieving the effect of drying;

[0046] The one-way baffle can close the opening of the second inclined portion 62 to prevent the rotating wheel 43 from sliding back from the second inclined portion 62 to perform a flipping motion. At the same time, the one-way baffle allows the rotating wheel 43 to rotate in the direction of the horizontal groove 231, that is, the transmission assembly 4 can perform a flipping motion in the flipping groove 6 and a horizontal rotation motion in the horizontal groove 231. When the transmission assembly 4 performs a flipping motion, the transmission member 42 can slide out from the second inclined portion 62. At this time, the transmission member 42 abuts the one-way baffle against the entrance of the horizontal groove 231 during the sliding out process, thereby allowing the transmission assembly 4 to continue to move along the bottom of the fixed disk; further, a one-way baffle should also be provided at the exit of the horizontal groove 231 near the first inclined portion 61, so that when the counterclockwise flipping motion occurs, the rotating wheel 43 can smoothly enter the first inclined portion 61 instead of the horizontal groove 231. The one-way baffle is a one-way rotating structure composed of a retaining spring and a baffle, which can be regarded as being implemented using existing technology as long as the one-way rotation function can be achieved.

[0047] In one embodiment, the mounting groove is flush with the bottom of the fixed disc 22, so that the center of gravity of the clamping assembly 5 moves along the track of the bottom of the fixed disc 22, the bottom of the guide seat 23 is lower than the bottom of the fixed disc 22 and the height of the guide seat 23 is less than the distance between the two rotating wheels 43, and the mounting groove is flush with the bottom of the fixed disc 22, that is, when the clamping assembly 5 performs a circular motion, its center of gravity always moves along the track of the bottom of the fixed disc 22, which helps to maintain the stability of the clamping assembly 5 during the flipping and drying process;

[0048] In the flipping stage, the transmission component 4 moves at the bottom of the fixed disc 22 and the flipping groove 6. Specifically, the rotating disc 41 drives the transmission member 42 and the two rotating wheels 43 to move along the trajectory of the flipping groove 6, and the clamping component 5 completes the flipping of 0-180°. The height of the guide seat 23 is just enough to allow one rotating wheel 43 to move from the flipping groove 6 and the other rotating wheel 43 to move from the bottom of the guide seat 23. The 0-90° stage is guided by the rotating wheel 43 entering the flipping groove 6, and the 90°-180° stage is guided by the rotating wheel 43 moving from the bottom of the guide seat 23. The two rotating wheels 43 cooperate with the flipping groove 6 and the guide seat 23 to complete the flipping of the transmission member 42, and then the transmission member 42 drives the clamping component 5 to complete the flipping of the PCR8 tube rack 8. In the flipping process, the cleaning of the spraying system 71 can be coordinated to achieve comprehensive automatic cleaning of the PCR8 tube rack 8.

[0049] During the spin-drying stage, the transmission assembly 4 moves between the fixed disc 22 and the horizontal groove 231. Specifically, the two rotating wheels 43 enter the horizontal groove 231. The clamping assembly 5 and the PCR8 tube rack 8 rotate horizontally counterclockwise under the action of centrifugal force to achieve the spin-drying effect. During the whole process, the center of gravity of the clamping assembly 5 always moves stably along the trajectory at the bottom of the fixed disc 22.

[0050] In one embodiment, the clamping assembly 5 includes a connecting seat 51, two clamping jaws 52, a gear 53 and an abutting seat 54; the connecting seat 51 is connected to the transmission member 42, the two clamping jaws 52 are symmetrically arranged on both sides of the connecting seat 51, the gear 53 is rotatably mounted on the connecting seat 51 and is located between the two clamping jaws 52, the two clamping jaws 52 are both provided with a gear 53, and the two gears 53 are both meshed with the gear 53; the abutting seat 54 is mounted on the outer ring of the rotating disk 41, and the thickness of the abutting seat 54 gradually increases along the direction of movement of the clamping jaws 52, and the abutting seat 54 is used to abut a clamping jaw 52, ​​so that the two clamping jaws 52 can be rotated. The claw 52 replaces the clamping PCR8 tube rack 8; the connecting seat 51 can rotate relative to the rotating disk 41. When the connecting seat 51 rotates, the claw 52 on one side abuts against the abutting seat 54. Due to the gradual increase and decrease in the thickness of the abutting seat 54, the abutting seat 54 abuts against the movement of a claw 52, ​​and due to the meshing relationship of the gear 53, the movement of the claw 52 will drive the gear 53 to rotate, and the rotation of the gear 53 will drive the two claws 52 to open and close in opposite directions, thereby realizing the alternating clamping of the PCR8 tube rack 8 by the two claws 52, and further realizing the comprehensive cleaning of the PCR8 tube rack 8.

[0051] In one embodiment, it also includes a spraying system 71, a water inlet system 72 and a water outlet system 73; the water inlet system 72 is equipped with at least two liquid storage tanks, and the two liquid storage tanks are used to configure disinfectant; the water inlet system 72 is connected to the spraying system 71, the spraying system 71 is used to spray disinfectant into the cleaning space 11, and the water outlet system 73 is used to drain the sewage in the cleaning space 11. The water inlet system 72 includes at least two independent liquid storage tanks, which are respectively used to store different types of disinfectants or different concentrations of the same disinfectant to meet different cleaning needs or improve the cleaning effect. The user can configure an appropriate amount of disinfectant in the liquid storage tank in advance according to the actual cleaning needs; when the cleaning program is started, the water inlet system 72 According to the preset program or user instructions, an appropriate liquid storage tank is selected as the source of disinfectant, and the disinfectant is transported to the spraying system 71 through a pipeline. The spraying system 71 adopts a nozzle array, which can evenly and efficiently spray the disinfectant to the PCR8 tube rack 8 to ensure that the disinfectant fully covers all surfaces to be cleaned; the disinfectant stays on the PCR8 tube rack 8 for a certain period of time, or the test tube rack is soaked for a period of time to fully dissolve and remove the residues, stains and microorganisms attached to the tube rack. In this process, the spraying frequency and duration can be adjusted as needed to achieve the best cleaning effect. After the cleaning is completed, the water outlet system 73 is started to quickly discharge the sewage and residual disinfectant in the cleaning space 11 through the drainage pipe.

[0052] In one embodiment, it also includes a drying system, which is used to dry the PCR8 tube rack 8 after disinfection. The drying system may adopt hot air drying, infrared drying or other high-efficiency drying technologies. The heat source such as hot air or infrared rays acts evenly on the PCR8 tube rack 8 through a specific drying device (such as a drying box, a drying tunnel, etc.) to quickly remove residual moisture; it also includes ultraviolet lamp 9 disinfection. When the ultraviolet lamp 9 disinfects, the drive component 3 is started to rotate clockwise, so that the PCR8 tube rack 8 flips over, thereby achieving comprehensive disinfection of the PCR8 tube rack 8.

[0053] In one embodiment, a control system is also included, and the spraying system 71, the water inlet system 72, the water outlet system 73, the drying system and the driving component 3 are all connected to the control system and driven by the control system. The control system is equipped with a user-friendly operation interface, such as a touch screen, a button panel or a remote control terminal, allowing the user to input the parameters of cleaning and drying (such as the type and concentration of the disinfectant, the spraying time, the drying temperature and time, etc.), and the control system monitors the working status of each system and the cleaning and drying progress of the PCR8 tube rack 8 in real time through a sensor network (such as a liquid level sensor, a temperature sensor, a humidity sensor, etc.);

[0054] The control system coordinates the actions of the spraying system 71, the water inlet system 72, the water outlet system 73, the drying system and the drive assembly 3 according to the user instructions and the system status. In the cleaning stage, the control system will first start the water inlet system 72 to select and deliver the disinfectant to the spraying system 71, and then start the spraying system 71 for spraying, and at the same time start the drive system to rotate clockwise, so that the PCR8 tube rack 8 is turned over for comprehensive cleaning; after the cleaning is completed, the control system will turn off the spraying system 71 and start the water outlet system 73 for drainage; after the drainage is completed, the control system will start the drying system for drying. When drying or spinning, the drive assembly 3 rotates counterclockwise, and the PCR8 tube rack 8 seats move horizontally in a circular motion, generating centrifugal force to further spin off the water stains;

[0055] The control system supports the setting of automated processes and scheduled tasks, allowing users to preset a series of cleaning and drying operations according to experimental plans or schedules, and automatically execute them at the specified time. This not only improves the efficiency of system use, but also reduces manual intervention and reduces operational risks.
