Description

Technical Field

[0001] This invention relates to the field of culture medium dispensing technology, and more specifically, to a lifting and shaking mixing device and a culture medium dispensing system including the device. Background Technology

[0002] Culture medium dispensing systems are crucial equipment in the field of biology. In a fully automated dispensing system, the main operational steps are: detaching the dish lid from the dish body, adding culture medium into the dish, and then reattaching the lid to the dish body to complete the automated dispensing. However, if samples or culture medium additives need to be added, the existing mechanisms and operational steps prevent proper mixing, causing the samples or additives to accumulate. This accumulation results in overlapping colonies, making colony counting impossible and affecting experimental results.

[0003] To achieve even mixing, the clutch turntable is shaken and vibrated slightly. However, this method has several disadvantages: First, the slight shaking and vibration during mixing causes the culture dish to collide with the turntable, resulting in loud noise and poor mixing effect. Second, during the culture medium dispensing process, the culture medium temperature is controlled at around 50℃ (if the culture medium temperature is too high, the amount of condensation on the dish lid will be large; if the temperature is too low, it will start to solidify during dispensing, which is not conducive to the even spreading of the culture medium). After pouring and spreading evenly, cooling and solidification are started. If the culture dish is vibrated by external force during the cooling and solidification process, it will cause the surface of the culture medium to be wavy and uneven, affecting the quality of the culture medium.

[0004] Therefore, the urgent problem to be solved in this technical field is to improve the shaking device of the culture medium dispensing system so that the shaking amplitude is close to the action of manual operation, so as to uniformly mix the sample or additive with the culture medium; the related equipment does not need to shake and mix repeatedly, so as to avoid the surface of the semi-solidified culture medium being wavy after cooling. Summary of the Invention

[0005] To overcome the above deficiencies, the present invention provides a lifting and shaking mixing device and a culture medium dispensing system containing the device, aiming to improve the problems mentioned in the background art.

[0006] The present invention provides a lifting and shaking mixing device, including a base, a rotary motor is arranged inside the base, a telescopic motor is arranged below the rotary motor, and the output shaft of the telescopic motor is connected to the rotary motor; an inclined rocking disk is arranged on the output shaft of the rotary motor.

[0007] As an improvement to the lifting and shaking mixing device of this utility model, the upper surface of the inclined shaking disk is inclined.

[0008] As a further improvement to the lifting and shaking mixing device of this utility model, a shaking disk connecting flange is provided on the output shaft of the rotary motor, and the shaking disk connecting flange is fixedly connected to the lower surface of the inclined shaking disk.

[0009] As a further improvement to the lifting and shaking mixing device of this utility model, a rotary motor mounting base made of engineering plastic with self-lubricating function is provided between the base and the rotary motor.

[0010] As a further improvement to the lifting and shaking mixing device of this utility model, a protective plate is provided directly above the rotary motor mounting base.

[0011] As a further improvement to the lifting and shaking mixing device of this utility model, a lower flange of the base is provided below the base, the telescopic motor is fixedly connected to the lower flange of the base, and the output shaft of the telescopic motor passes through the lower flange of the base and is connected to the lower part of the rotary motor.

[0012] As a further improvement to the lifting and shaking mixing device of this utility model, a telescopic motor adapter is provided on the output shaft of the telescopic motor, and the telescopic motor adapter is fixedly connected to the lower part of the rotary motor.

[0013] As a further improvement to the lifting and shaking mixing device of this utility model, a limit system is provided below the telescopic motor.

[0014] As a further improvement to the lifting and shaking mixing device of this utility model, the limiting system includes a proximity switch mounting bracket, a proximity switch mounting plate is provided on the proximity switch mounting bracket, and a proximity switch is fixed on the proximity switch mounting plate.

[0015] A culture medium dispensing system includes a chassis panel with a culture dish clutch turntable. The culture dish clutch turntable has several culture dish positioning slots for holding a corresponding number of culture dishes. The culture dish positioning slots are provided with inclined shaking disc telescopic holes. The inclined shaking disc is located directly below the culture dish.

[0016] In summary, the beneficial effects of this invention are: By using a sloping shaking plate that is in close contact with the lower side of the culture dish, the shaking amplitude during the mixing process is close to that of manual operation, so that the sample or additive is evenly mixed with the culture medium. Moreover, this type of shaking action eliminates the need for repeated shaking and mixing, and avoids the surface of the semi-solidified culture medium becoming wavy after cooling.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Figures 1-4A lifting and shaking mixing device is provided, including a base 2 (the base 2 has a cavity that runs vertically through it), a rotary motor mounting seat 110 is provided inside the base 2, and a rotary motor 11 is fixed inside the rotary motor mounting seat 110. The rotary motor 11 (rotary motor mounting seat 110) needs to move up and down along the inner cavity of the base 2. Therefore, the rotary motor mounting seat 110 will rub against the inner cavity wall of the base 2. In order to minimize the scratches on the mechanism and ensure smooth movement, the rotary motor mounting seat 110 is made of engineering plastic with self-lubricating function.

[0021] A protective plate 111 (to prevent external debris from entering the machine base 2) is fixed directly above the rotary motor mounting base 110. The protective plate 111 has a hole through which the output shaft of the rotary motor 11 passes, and a rocking disc connecting flange 101 is fixed. The rocking disc connecting flange 101 is fixedly connected to the lower surface of the inclined rocking disc 10. The upper surface of the inclined rocking disc 10 is inclined, and its structure is as follows... Figure 3 As shown, its cross-section is a right-angled trapezoidal structure. With this design, when the rotary motor 11 rotates, the inclined shaking disk 10 and the bottom of the culture dish 1002 are flatly attached, so that the culture dish 1002 does not rotate and shake on a horizontal plane. The shaking action is an undulating rotation, which greatly improves the shaking effect.

[0022] A lower flange 21 is fixed below the base 2, and a telescopic motor 12 is fixed below the lower flange 21. The output shaft of the telescopic motor 12 (in this embodiment, the telescopic motor 12 is a through-type telescopic motor, which passes through the motor via a lead screw to complete the longitudinal displacement of the output shaft; therefore, the motor output shaft here is actually a lead screw) passes through the lower flange 21 and is connected to the lower part of the rotary motor 11 via a telescopic motor adapter 121 (the control of the vertical displacement of the lead screw output shaft of the telescopic motor via the adapter is existing technology and will not be elaborated here).

[0023] like Figure 4As shown, a limit switch system is provided below the telescopic motor 12. This system includes a proximity switch mounting bracket 130, a proximity switch mounting plate 131, and a proximity switch 132. The proximity switch 132 is fixed to the proximity switch mounting plate 131. The proximity switch mounting bracket 130 is fixed below the lower flange 21 of the base. The proximity switch mounting bracket 130 has a groove 1301, through which the proximity switch mounting plate 131 and the proximity switch mounting bracket 130 are positioned. The proximity switch mounting plate 131 has an elongated hole 1310, which is bolted into the groove 1301 of the proximity switch mounting bracket 130. In this configuration, the elongated hole 1310 corresponds to the screw hole of the proximity switch mounting bracket 130, allowing for adjustable fixation (correspondingly, the adjustment of the proximity switch mounting bracket 130 can drive the adjustment of the proximity switch 132). Therefore, the proximity switch 132 can be adjusted up and down within the groove 1301.

[0024] Example 2 Figures 5-9 A culture medium dispensing system is provided, including a chassis panel 1000, on which a culture dish clutch turntable 1001 is provided. A number of culture dish bodies 1002 are provided on the culture dish clutch turntable 1001 through culture dish positioning grooves 1005. The culture dish positioning grooves 1005 are provided with inclined shaking disk telescopic holes 1006. The inclined shaking disk 10 is located directly below the culture dish body 1002. When the inclined shaking disk 10 is extended, it can pass through the inclined shaking disk telescopic holes 1006 and directly abut against the lower surface of the culture dish body 1002.

[0025] The operating flow of Embodiments 1 and 2 of this utility model is as follows (this mechanism can be controlled in conjunction with a control system during operation): When the culture dish clutch turntable 1001 rotates the culture dish body 1002 containing culture medium 1003 (with sample or additives added) to the inclined shaking disk 10 corresponding to the inclined shaking disk telescopic hole 1006, the output shaft of the telescopic motor 12 drives the rotary motor 11 to rise, so that the inclined shaking disk 10 is attached to the bottom surface of the culture dish body 1002, and the culture dish body 1002 is disengaged from the culture dish positioning groove 1005 of the culture dish clutch turntable 1001. The rotary motor 11 starts rotating, and the inclined plane rocking disk 10 starts rotating, creating a rocking motion on the inclined plane. Furthermore, the number of rotations and the duration of the rotary motor's rotation can be controlled by the system program. After the culture medium 1003 is shaken well with the sample (or additive), the rotary motor 11 stops rotating, the output shaft of the telescopic motor 12 retracts, and drives the rotary motor 11 and the inclined shaking disk 10 back to the starting position (at this time, the inclined shaking disk 10 is a certain distance from the bottom of the culture dish clutch turntable 1001 to avoid blocking the culture dish clutch turntable 1001 when it rotates).

[0026] The output shaft of the telescopic motor 12 returns to its initial position, and the output shaft (telescopic lead screw) extends from the bottom of the telescopic motor. The proximity switch 132 detects the extended output shaft (telescopic lead screw), and the telescopic motor 12 stops running. Furthermore, the proximity switch 132 feeds back the signal of the telescopic motor 12 returning to the starting point to the control system. After receiving the signal, the control system rotates the culture dish clutch turntable 1001 and then sends the next culture dish 1002 to the position corresponding to the telescopic hole 1006 of the inclined shaking plate to repeat the shaking action.

[0027] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
