Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to a fully automatic microorganism culture system and a magnetic attraction shaking drive mechanism thereof. Background Art

[0002] Chinese Patent with publication number CN217202771U discloses an assembled microorganism incubation unit. By setting a shaking drive mechanism to drive the incubation module to shake, the growth of microorganisms can be accelerated; by installing the drive motor in the control area, the heat generated during the operation of the drive motor is prevented from affecting the temperature inside the incubation cabinet, and the temperature inside the incubation cabinet is prevented from exceeding the rated value; since the drive motor is installed in the control area and the drawer bracket is slidably matched with the incubation cabinet, that is, the drive motor cannot move synchronously with the drawer bracket, a clutch mechanism needs to be set. Specifically, when the drawer bracket slides out from the opening of the incubation cabinet, the clutch mechanism disengages, and at this time, the incubation module stops shaking; when the drawer bracket is slid into the incubation cabinet, the clutch mechanism engages, and the drive motor can drive the incubation module to shake. Although the existing assembled microorganism incubation unit can meet the usage requirements of microorganism incubation and improve space utilization, the applicant found the following deficiencies in the use process: (1) The power transmission of the drive motor mainly realizes the shaking of the incubation module through five transmission chains such as the motor synchronous belt, clutch mechanism, clutch driven synchronous belt, crank rocker mechanism, and shaking link mechanism. The long transmission chain makes the function realization complex and the instrument installation process complex; (2) For the first transmission chain of the power transmission of the drive motor, the power is transmitted through a synchronous pulley mechanism. The axes of the two synchronous pulleys are fixed in a "cantilever beam" manner and are connected by a belt in the middle. Since the driving torque for driving the incubation module to shake is relatively large, the belt needs to provide a large pulling force, resulting in the axes of the two synchronous pulleys approaching and tilting towards each other, and the belt sliding towards the outside of the synchronous pulley, causing wear, chip removal, and abnormal noise with the synchronous pulley, and there are risks of belt breakage and noise problems; (3) For the second transmission chain of the power transmission of the drive motor, the power is transmitted through a clutch mechanism. After the first clutch column on the first clutch disc and the second clutch column on the second clutch disc are combined, the power transmission is realized through the tangential force; when the clutch mechanism switches from the disengaged state to the engaged state, since the end diameters of the first clutch column and the second clutch column are not zero, there is a situation of jamming after the end contacts at the beginning; when the clutch mechanism is in the engaged state, since the inner diameter of the distribution circle of the first clutch column is larger than the inner diameter of the distribution circle of the second clutch column, there is a partial gap between the second clutch columns in the middle of every two first clutch columns. When the drive motor starts, the first clutch column on the first clutch disc starts to rotate first, and then moves to contact the second clutch column. During this period, there is a contact collision movement, and there are risks of collision damage of each clutch column and noise problems. Summary of the invention

[0003] In view of this, in order to solve the problems existing in the prior art, the purpose of the present invention is to provide a fully automatic microbial cultivation system and a magnetic suction and shaking drive mechanism thereof.

[0011] The present invention also proposes a fully automatic microbial cultivation system, comprising an incubation cabinet and a drawer bracket installed in the incubation cabinet, at least one incubation module is installed in the drawer bracket, the drawer bracket and the incubation cabinet are arranged to move relative to each other, and a magnetic attraction and shaking drive mechanism is provided between the incubation cabinet and the drawer bracket; The magnetic attraction shaking driving mechanism includes a shaking connecting rod assembly and a shaking driving assembly; the shaking driving assembly includes an active driving assembly and a driven driving assembly; The active drive assembly is installed on the incubation cabinet, and the active drive assembly includes a drive motor located outside the drawer bracket and a magnetic clutch driving wheel drivingly connected to the drive motor; The driven drive assembly comprises a driven shaft mounted on the drawer bracket and a magnetic clutch driven wheel drivingly connected to the driven shaft; The magnetic clutch driving wheel and the magnetic clutch driven wheel cooperate with each other to form a magnetic attraction transmission mechanism; The shaking connecting rod assembly is installed on the drawer bracket or the incubation module, and the shaking connecting rod assembly transmission connects the magnetic clutch driven wheel with the incubation module.

[0012] Furthermore, the magnetic clutch driving wheel is sleeved on the output shaft of the drive motor and rotates synchronously with the output shaft of the drive motor; the magnetic clutch driven wheel is sleeved on the driven shaft and rotates synchronously with the driven shaft; the rotating axes of the magnetic clutch driving wheel and the magnetic clutch driven wheel are perpendicular to each other.

[0013] The present invention also proposes a fully automatic microbial cultivation system, comprising an incubation cabinet and a drawer bracket installed in the incubation cabinet, at least one incubation module being installed in the drawer bracket, the drawer bracket being arranged to move relative to the incubation cabinet, and a magnetic suction and shaking drive mechanism as described above being arranged between the incubation cabinet and the drawer bracket; the drive motor is located outside the drawer bracket; the first mounting plate is arranged on the incubation cabinet, and the second mounting plate is arranged on the drawer bracket.

[0015] Further, the second mounting plate can move relative to the first mounting plate along a direction parallel to the axis of the driven shaft; a guiding assembly for guiding the drawer bracket to move along a direction parallel to the driven shaft is provided between the incubation cabinet and the drawer bracket.

[0016] The beneficial effects of the present invention are as follows: In the full-automatic microorganism culture system of the present invention, a magnetic attraction shaking driving mechanism is provided between the incubation cabinet and the incubation bracket, an active driving component is provided on the incubation cabinet, and a driven driving component is provided on the drawer bracket. In this way, the non-contact transmission method between the magnetic clutch driving wheel and the magnetic clutch driven wheel is utilized: when the drawer bracket is pulled out of the incubation cabinet, the magnetic clutch driving wheel and the magnetic clutch driven wheel are separated, and the active driving component and the driven driving component are not in a transmission connection; when the drawer bracket is pushed into the incubation cabinet, the magnetic clutch driving wheel and the magnetic clutch driven wheel are in non-contact coupling, and the driving power on the magnetic clutch driving wheel can be transmitted to the magnetic clutch driven wheel, so that the incubation module can be driven to shake through the shaking link assembly, and the following technical effects are achieved: (1) The magnetic attraction transmission mechanism is adopted to replace the existing synchronous belt mechanism and clutch, which can effectively reduce the transmission chain and simplify the structure; at the same time, since the synchronous belt mechanism is no longer used, there is no problem of synchronous belt wear. (2) The magnetic clutch driving wheel and the magnetic clutch driven wheel in the magnetic attraction transmission mechanism are in a non-contact transmission method, which can avoid the jamming and collision problems when the drawer bracket is pushed into the incubation cabinet, and no collision abnormal sound will be generated, achieving an unexpected technical effect of solving the jamming and non-smoothness of the existing clutch during the separation and combination process.

[0017] (3) Fundamentally solved the problem of synchronous belt chipping: Specifically, on the one hand, the motors of the instruments on the market are not externally placed, so there is no need to set a clutch structure in the fully automatic microbial culture systems of these instruments. However, the heat generated by the motors will affect the microbial incubation temperature. On the other hand, in order to avoid the influence of motor heat on microbial incubation, in the prior application with the publication number CN217202771U proposed by the applicant, the motor is externally placed. Although the heat generated by the motor is isolated, the problem of chipping is caused due to the addition of a clutch structure. Through the research of the applicant, it is found that the reason for chipping is as follows: The transmission mechanism needs to be designed as a cantilever beam structure. Due to the natural defects in the design of the cantilever beam structure, and at the same time, due to the large driving torque for driving the incubation module to shake, the synchronous belt needs to provide a large tensile force, resulting in the axes of the two synchronous belt wheels approaching and tilting towards each other, and the belt sliding towards the outside of the synchronous belt wheel. In this special scenario, various factors exacerbate the problem of belt wear and chipping. Therefore, in the fully automatic microbial culture system of the present invention, by adopting a magnetic attraction shaking drive mechanism to replace the traditional clutch structure, the problem of synchronous belt chipping is fundamentally solved.

[0018] (4) Since the transmission mechanism needs to be designed as a cantilever beam structure, if the magnetic clutch driving wheel and the magnetic clutch driven wheel are coaxially arranged or arranged parallel to each other, it will lead to a complex transmission chain, an increase in the number of components, an increase in tolerance accumulation, and at the same time, problems such as abnormal noise and abnormal wear may also occur. By setting the rotating shafts of the magnetic clutch driving wheel and the magnetic clutch driven wheel to be perpendicular to each other, the present invention can solve the above technical problems.

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0022] like Figures 1-3 As shown, the fully automatic microbial culture system of this embodiment includes an incubation cabinet 10 and a drawer bracket 20 installed in the incubation cabinet, at least one incubation module 21 is installed in the drawer bracket 20, and the drawer bracket 20 and the incubation cabinet 10 are relatively movable, that is, the drawer bracket 20 and the incubation cabinet 10 can move relative to each other, so that the incubation module 21 can be moved, so as to put or take out the incubated objects into or out of the incubation module 21. Specifically, a magnetic shaking drive mechanism is provided between the incubation cabinet 10 and the drawer bracket 20 of this embodiment. Specifically, in this embodiment, the magnetic shaking drive mechanism includes a shaking connecting rod assembly 30 and a shaking drive assembly. The shaking drive assembly of this embodiment includes an active drive assembly 40 and a driven drive assembly 50.

[0023] like Figures 3-5 As shown, the active drive assembly 40 of this embodiment includes a drive motor 41 fixedly mounted on a first mounting plate 44 and a magnetic clutch driving wheel 42 transmission-connected to the drive motor 41. Specifically, in this embodiment, the magnetic clutch driving wheel 42 is sleeved on the output shaft of the drive motor 41 and rotates synchronously with the output shaft of the drive motor 41, which can simplify the structure. Of course, in some other embodiments, the rotating shaft of the magnetic clutch driving wheel 42 and the output shaft of the drive motor 41 can also be connected to each other by a synchronous belt mechanism, a gear transmission mechanism, and a chain transmission mechanism, which will not be described in detail.

[0024] like Figures 3-5As shown, the driven drive assembly 50 of this embodiment includes a driven shaft 51 rotatably mounted on the second mounting plate 22 and a magnetic clutch driven wheel 52 drivingly connected to the driven shaft 51. In this embodiment, a driven shaft seat 53 is provided on the second mounting plate 22, and the driven shaft 51 is rotatably mounted in the driven shaft seat 53, which can effectively improve the rotational stability of the driven shaft 51. In this embodiment, the magnetic clutch driven wheel 52 is sleeved on the driven shaft 51 and rotates synchronously with the driven shaft 51, which can effectively simplify the structure. Of course, in some other embodiments, the magnetic clutch driven wheel 52 and the driven shaft 51 can also be drivingly connected by means of a synchronous belt mechanism, a gear transmission mechanism, a chain transmission mechanism, etc., which will not be elaborated here.

[0025] Specifically, the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52 cooperate with each other to form a magnetic attraction transmission mechanism. In this embodiment, the axes of rotation of the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52 are perpendicular to each other, that is, in this embodiment, the output shaft of the drive motor 41 and the driven shaft 51 are perpendicular to each other.

[0026] In this embodiment, the second mounting plate 22 can move relative to the first mounting plate 44 so that the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52 are separated or in non-contact coupling. In this embodiment, the second mounting plate 22 can move relative to the first mounting plate 44 along a direction parallel to the axis of the driven shaft 51. Specifically, when the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52 are separated, since the distance between the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52 is relatively far, there is no power transmission between the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52; when the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52 are in non-contact coupling, the distance between the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52 is relatively small, and the power on the magnetic clutch driving wheel 42 can be transmitted to the magnetic clutch driven wheel 52.

[0027] As Figure 3 shown, in this embodiment, the first mounting plate 44 is mounted on the incubator 10 or integrated with the incubator 10, that is, the active drive assembly 40 of this embodiment is mounted on the incubator 10. Preferably, the drive motor 41 is mounted on the incubator 10 and located outside the drawer bracket 20 to prevent the heat generated by the drive motor 41 from affecting the incubation temperature. In this embodiment, the second mounting plate 22 is provided on the drawer bracket 20 or integrated with the drawer bracket 20, that is, in this embodiment, the driven shaft 51 is rotatably mounted on the drawer bracket 20.

[0028] In this embodiment, the shaking link assembly 30 is installed and drivingly connected to the driven drive assembly. The shaking link assembly 30 is installed on the drawer bracket 20 or the incubation module 21. In this embodiment, the shaking link assembly 30 is installed on the drawer bracket 20. Specifically, the drawer bracket 20 includes a front drawer end plate and a rear drawer end plate respectively located at the front and rear ends of the incubation module 21, and the shaking link assemblies 30 are respectively provided on the front drawer end plate and the rear drawer end plate. The first mounting plate 44 is the top plate of the incubation cabinet 10 or is mounted on the top surface of the incubation cabinet 10. In this embodiment, the first mounting plate 44 is mounted on the top plate of the incubation cabinet 10. In this embodiment, the second mounting plate 22 is the front drawer end plate or the rear drawer end plate, or the second mounting plate is mounted on the front drawer end plate or the rear drawer end plate. Specifically, when the second mounting plate 22 is the front drawer end plate or is mounted on the front drawer end plate, the active drive assembly is arranged at the front end of the incubation cabinet 10, and the shaking link assembly 30 arranged on the front drawer end plate is drivingly connected to the driven drive assembly; when the second mounting plate 22 is the rear drawer end plate or is mounted on the rear drawer end plate, the active drive assembly is arranged at the rear end of the incubation cabinet 10, and the shaking link assembly 30 arranged on the rear drawer end plate is drivingly connected to the driven drive assembly. In this embodiment, the second mounting plate 22 is the rear drawer end plate.

[0029] In this embodiment, the second mounting plate 22 can move relative to the first mounting plate 44 along a direction parallel to the axis of the driven shaft 51; a guiding assembly (not shown in the figure) for guiding the drawer bracket to move along a direction parallel to the driven shaft is provided between the incubation cabinet and the drawer bracket. The guiding assembly can be a guiding track or the like provided between the incubation cabinet and the drawer bracket, and will not be elaborated here.

[0030] In a preferred embodiment of this embodiment, a motor heat insulation sheet 43 is provided between the drive motor 41 and the first mounting plate 44, which can prevent the heat generated by the drive motor 41 from being conducted into the incubation cabinet 10 and avoid affecting the temperature inside the incubation cabinet 10.

[0031] In a preferred embodiment of this embodiment, the transmission ratio of the magnetic attraction transmission mechanism is 2:1, that is, the transmission ratio between the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52 is 2, which increases the upper limit of the maximum transmission torque of the shaking drive assembly, can directly replace the shaking drive assembly of the existing fully automatic microorganism culture system, and ensure that the swinging speed of the incubation module 21 is consistent.

[0032] As Figures 3-5As shown in the figure, in this embodiment, the driven drive assembly 50 further includes a drive rod 54 and an eccentric shaft 55 that is eccentrically arranged relative to the driven shaft 51. The eccentric shaft 55 can rotate synchronously with the driven shaft 51 around the axis of the driven shaft 51, and the first end of the drive rod 51 is hinged to the eccentric shaft 55. In this embodiment, the shaking link assembly 30 includes a linkage rod 31 and a plurality of parallel support rods 32; the first end of the support rod 32 is hinged to the linkage rod 31 through a first shaft 33, and the second end of the support rod 32 is hinged to a second shaft 34 provided on the second mounting plate 22; the second end of the drive rod 51 is hinged to one of the first shafts 33.

[0033] As Figure 4 shown, in the preferred embodiment of this embodiment, an optocoupler sensor 23 is installed on the second mounting plate 22. The optocoupler sensor 23 is used to detect the angular range of the first end of the support rod 32 rotating around the second shaft 34. Specifically, in this embodiment, a measuring rod 35 corresponding to one of the support rods 32 is installed on the second mounting plate 21. The first end and the second end of the measuring rod 35 are respectively hinged to the corresponding first shaft 33 and the second shaft 34, and the optocoupler sensor 23 is used to detect the angular range of the first end of the measuring rod 35 rotating around the second shaft 34. In this embodiment, two optocoupler sensors 23 are provided, and the two optocoupler sensors 23 are respectively used to detect the two end positions of the angular range of the first end of the measuring rod 35 rotating around the second shaft 34. An induction sheet 35 cooperating with the optocoupler sensor 23 is provided on the measuring rod 35 of this embodiment.

[0034] The principle of the full-automatic microorganism culture system of this embodiment driving the incubation module 21 to shake through the magnetic attraction shaking drive mechanism is as follows: After the drawer bracket 20 is pushed into the incubation cabinet 10, there is no contact coupling between the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52 and power transmission can be achieved; the driving motor 41 is started to drive the magnetic clutch driving wheel 42 to rotate. Using the coupling relationship between the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52, the magnetic clutch driven wheel 52 is driven to rotate, and then the driven shaft 51 and the eccentric shaft 55 are driven to rotate. Since the eccentric shaft 55 is eccentrically arranged relative to the driven shaft 51, in this way, the first end of the drive rod 54 can be driven to swing, and then the first shaft 33, the linkage rod 31 and the support rod 32 are driven to swing around the second shaft 34, and finally the incubation module 21 is driven to shake by the support rod 32. When the drawer bracket 20 is pulled out of the incubation cabinet 10, the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52 are separated, and power transmission cannot be carried out between the magnetic clutch driving wheel 42 and the magnetic clutch driven wheel 52.

Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention. The protection scope of the present invention is subject to the claims.
