[0054] The present application will now be described by way of specific embodiments thereof, and as the skilled person will readily appreciate from the disclosure contained herein, other advantages and effects of the present application will be readily appreciated. Although the present application will be described with reference to the preferred embodiments, it is to be understood that the present application is not limited to the preferred embodiments. Rather, the preferred embodiments are intended to cover all alternatives, modifications and equivalents falling within the scope of the present application as defined by the appended claims. In order to provide a thorough understanding of the present application, numerous specific details about the preferred embodiments are included. The present application can be practiced without these specific details. In addition, well-known elements are not shown or described in detail in order to avoid obscuring the novelty of the present application. It is to be understood that the embodiments and features of the present application can be combined with each other, if not in contradiction.

[0055] With reference to Figures 1 to 7 , the present application provides a photographing device 1, which is installed on a microscope. The photographing device 1 comprises a main board 10, a supporting part 20, a driving assembly 40 and a rotating disc 30. The supporting part 20 is arranged along a first direction (Figures 1 to 3 , Figures 6 to 7 Extending in the Z-direction, the support portion 20 is vertically mounted on the main board 10. Exemplarily, the support portion 20 is plate-shaped. A drive assembly 40 is mounted on the support portion 20 and has a support shaft 41 extending in a first direction. A rotating disk 30 is parallel to the main board 10 and is fixedly connected to the support shaft 41. In other words, the support shaft 41 is positioned perpendicular to the rotating disk 30. The rotating disk 30 of this application is equipped with a first camera 50 and a second camera 60, which are used to photograph the observation sample placed on the microscope for imaging analysis and research.

[0056] like Figure 4 As shown, the rotating disk 30 is provided with a first imaging through-hole 501 corresponding to the first camera 50 and a second imaging through-hole 601 corresponding to the second camera 60. The first camera 50 takes pictures of the observed sample through the first imaging through-hole 501, and the second camera 60 takes pictures of the observed sample through the second imaging through-hole 601.

[0057] For example, the term "sample" as used above encompasses clinical samples, such as cultured cells, cell supernatants, cell lysate products, serum, plasma, biofluids, and tissue samples, as well as various precision devices, such as optical crystals, semiconductor devices, and precision mechanical devices.

[0058] The drive component 40 of this application is capable of driving the rotating disk 30 circumferentially. Figure 3 and Figure 5 The first camera 50 rotates at a first angle (as shown in the T-direction) to a first position; or, the drive assembly 40 can drive the rotating disk 30 to rotate circumferentially by a second angle to a second position. In the first position, the first camera 50 is used to photograph the observation sample placed on the microscope; in the second position, the second camera 60 is used to photograph the observation sample. Exemplarily, in both the first and second positions, the motherboard 10 does not affect the first camera 50 and the second camera 60 from photographing the observation sample in the first direction.

[0059] Essentially, the imaging device 1 of this application provides two cameras. By switching the position of the rotating disk 30 in the circumferential direction (first position or second position), the use of the first camera 50 and the second camera 60 can be switched so that the sample can be observed through different cameras, thereby enabling different imaging analyses and studies, improving the convenience of the user in using the microscope and the efficiency of imaging analysis.

[0060] For example, the first camera 50 is a bright field camera and the second camera 60 is a fluorescence camera. When the driving assembly 40 drives the rotating disc 30 to rotate by a first angle in a circumferential direction to the first position, the photographing device 1 is in a bright field imaging mode, and bright field illumination imaging can be realized to observe the sample by the bright field camera (i.e. the first camera 50). When the driving assembly 40 drives the rotating disc 30 to rotate by a second angle in a circumferential direction to the second position, the photographing device 1 is in a fluorescence imaging mode, and fluorescence illumination imaging can be realized to observe the sample by the fluorescence camera (i.e. the second camera 60). Thus, the photographing device 1 can switch between the bright field imaging mode and the fluorescence imaging mode, and realize bright field illumination imaging and fluorescence illumination imaging, respectively.

[0061] In some possible embodiments, the driving assembly 40 can drive the rotating disc 30 to rotate by the first angle in a positive direction in a circumferential direction to the first position, or to rotate by the second angle in a negative direction in a circumferential direction to the second position. That is, the rotating disc 30 can switch between the positions in the circumferential direction by positive rotation or negative rotation of the driving assembly 40. In this way, the accuracy of the driving assembly 40 in controlling the rotation of the rotating disc 30 in the circumferential direction is improved.

[0062] In some possible embodiments, the first angle is equal to the second angle.

[0063] In addition, the specific values of the first angle and the second angle are not limited, and can be set according to actual photographing requirements. For example, the first angle and the second angle are 15°, 20°, 30°, etc.

[0064] In some possible embodiments, with reference to Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 , the rotating disc 30 is provided with the first positioning member 31 and the second positioning member 32, and the main plate 10 is provided with the third positioning member 33 and the fourth positioning member 34.

[0065] When the driving assembly 40 drives the rotating disc 30 to rotate in a circumferential direction to the first position, the first positioning member 31 and the third positioning member 33 cooperate with each other to limit the movement of the rotating disc 30 in the circumferential direction, and the first positioning member 31 and the third positioning member 33 are separated when the driving assembly 40 drives the rotating disc 30 to rotate from the first position to the second position.

[0066] When the driving assembly 40 drives the rotating disc 30 to rotate in a circumferential direction to the second position, the second positioning member 32 and the fourth positioning member 34 cooperate with each other to limit the movement of the rotating disc 30 in the circumferential direction, and the second positioning member 32 and the fourth positioning member 34 are separated when the driving assembly 40 drives the rotating disc 30 to rotate from the second position to the first position.

[0067] That is, when the rotating disk 30 is in the first position, the first positioning member 31 and the third positioning member 33 cooperate to position the rotating disk 30, enabling the first camera 50 to stably capture images of the observed sample and improve image quality. When the rotating disk 30 is in the second position, the second positioning member 32 and the fourth positioning member 34 cooperate to position the rotating disk 30, enabling the second camera 60 to stably capture images of the observed sample and improve image quality.

[0068] For example, the first positioning member 31 and the second positioning member 32 are along the second direction ( Figure 5 and Figure 7 The third positioning member 33 and the fourth positioning member 34 are spaced apart along the second direction (as shown in the X direction). The second direction is perpendicular to the first direction. The second direction is the extension direction of the main board 10.

[0069] For example, one of the first positioning member 31 and the third positioning member 33 is a first groove 371, and the other is a first bearing; one of the second positioning member 32 and the fourth positioning member 34 is a second groove 381, and the other is a second bearing.

[0070] Specifically, in this application, the first positioning member 31 and the second positioning member 32 are disposed on the portion of the rotating disk 30 facing the main board 10. The first positioning member 31 is a first groove, and the second positioning member 32 is a second groove. The third positioning member 33 and the fourth positioning member 34 are disposed on the portion of the main board 10 facing the rotating disk 30. The third positioning member 33 is a first bearing, and the fourth positioning member 34 is a second bearing. The main board 10 is provided with a first fixing rod 332 and a second fixing rod 341 extending along a first direction. The first bearing is sleeved on the first fixing rod 332, and the second bearing is sleeved on the second fixing rod 341. The portion of the main board 10 facing the rotating disk 30 is provided with a first fixing sheet metal 331 and a second fixing sheet metal 342. The first fixing rod 332 is mounted on the first fixing sheet metal 331, and the first bearing can rotate around the first fixing rod 332. The second fixing rod 341 is mounted on the second fixing sheet metal 342, and the second bearing can rotate around the second fixing rod 341.

[0071] When the drive assembly 40 drives the rotating disk 30 to rotate circumferentially to the first position, the first bearing is located in the first groove, which serves to position the rotating disk 30 and restrict its circumferential movement. When it is necessary to switch the rotating disk 30 to the second position, a relative rotation occurs between the first bearing and the first groove, causing the first positioning member 31 and the third positioning member 33 to separate, allowing the rotating disk 30 to continue moving circumferentially.

[0072] Similarly, when the driving assembly 40 drives the rotating disc 30 to rotate circumferentially to the second position, the second bearing is located in the second groove, which plays a role in positioning the rotating disc 30 and limiting the movement of the rotating disc 30 in the circumferential direction. When it is necessary to switch the rotating disc 30 to the first position, the second bearing and the second groove rotate relative to each other, so that the second positioning member 32 and the fourth positioning member 34 are separated, and the rotating disc 30 can continue to move in the circumferential direction.

[0073] For example, when the rotating disc 30 is in the first position and the second position, the driving assembly 40 stops working, so that the first camera 50 or the second camera 60 can stably shoot the observed sample.

[0074] In some possible embodiments, with reference to Figures 1 to 7 , the rotating disc 30 is provided with a first limiting member 35 and a second limiting member 36, and the main plate 10 is provided with a first limiter 37 and a second limiter 38. In the first position, the first limiting member 35 and the first limiter 37 cooperate with each other, and the driving assembly 40 stops working; in the second position, the second limiting member 36 and the second limiter 38 cooperate with each other, and the driving assembly 40 stops working. Wherein, the part of the main plate 10 facing the rotating disc 30 is provided with a third fixed metal sheet 372 and a fourth fixed metal sheet 382. The first limiter 37 is installed on the third fixed metal sheet 372, and the second limiter 38 is installed on the fourth fixed metal sheet 382.

[0075] That is, the driving assembly 40 drives the rotating disc 30 to rotate circumferentially by a first angle, and then the driving assembly 40 stops working. The driving assembly 40 drives the rotating disc 30 to rotate circumferentially by a second angle, and then the driving assembly 40 stops working. After such setting, the angle range of the rotating disc 30 rotating in the circumferential direction is limited, which prevents the driving assembly 40 from driving the rotating disc 30 to rotate in the circumferential direction unlimitedly, so as to prevent the shooting device 1 from being damaged and prolong the service life of the shooting device 1. At the same time, the rotating precision of the rotating disc 30 rotating in the circumferential direction by the first angle or the second angle is improved, which facilitates accurately controlling the switching of the position of the rotating disc 30 in the circumferential direction, so as to accurately control the shooting device 1 to use the first camera 50 or the second camera 60. Moreover, when the rotating disc 30 rotates circumferentially to the first position or the second position, the driving assembly 40 stops working, which can prevent the rotating disc 30 from continuing to rotate in the circumferential direction, and ensure that the rotating disc 30 is stably located in the first position or the second position, so that the first camera 50 and the second camera 60 can stably shoot the observed sample.

[0076] For example, the first limiter 37 and the second limiter 38 are arranged in the second direction (as indicated by the X direction in FIGS. 1 and 2) with a spacing. Figure 5 and Figure 7 X direction in FIGS. 1 and 2).

[0077] In some possible implementation manners, the first limiting member 35 and the second limiting member 36 are sheet metal parts, and the first limiting stopper 37 and the second limiting stopper 38 are respectively provided with a groove. The first limiting member 35 and the second limiting member 36 respectively have an extension part extending along the first direction. When the rotating disc 30 is at the first position, the first limiting member 35 rotates along the circumference until the extension part is located in the groove 371 of the first limiting stopper 37, and the driving assembly 40 stops working. When the rotating disc 30 is at the second position, the second limiting member 36 rotates along the circumference until the extension part is located in the groove 381 of the second limiting stopper 38, and the driving assembly 40 stops working.

[0078] In some possible implementation manners, referring to Figures 1 to 3 、 Figure 7 , the photographing device 1 further includes an encoder 70 mounted on the mainboard 10 and having an output shaft 70a extending along the first direction, a first synchronous wheel 701 fixedly arranged on the output shaft 70a, a second synchronous wheel 46 fixedly arranged on the support shaft 41, and a synchronous belt 702 having one end sleeved on the first synchronous wheel 701 and the other end sleeved on the second synchronous wheel 46. When the driving assembly 40 drives the support shaft 41 to rotate along the circumference, the second synchronous wheel 46 on the support shaft 41 rotates synchronously, thereby driving the first synchronous wheel 701 to rotate through the synchronous belt 702, and the output shaft 70a fixedly connected with the first synchronous wheel 701 also rotates along the circumference. By arranging the encoder 70, the angle of the support shaft 41 rotating along the circumference is controlled, and the rotating angle (the first angle or the second angle) of the rotating disc 30 rotating along the circumference is precisely controlled.

[0079] Continuing to refer to Figures 1 to 7 , the rotating disc 30 is provided with a through hole 301, and the support part 20 extends out of the through hole 301 along the first direction. For example, the through hole 301 on the rotating disc 30 is a sector hole. The driving assembly 40 further includes a motor 42 mounted on one end of the support part 20 extending out of the through hole 301 through a motor support seat 43, the motor support seat 43 is arranged along the first direction and spaced apart from the rotating disc 30, that is, the rotating disc 30 is suspendedly mounted on the photographing device 1, the support shaft 41 penetrates through the rotating disc 30 and is connected with the motor 42, the motor 42 is configured to drive the support shaft 41 to rotate along the circumference, a connecting part 47 protruding from the outer circumferential surface of the support shaft 41, the connecting part 47 is located between the rotating disc 30 and the mainboard 10, is attached to the part of the rotating disc 30 facing the mainboard 10, and is fixedly connected with the rotating disc 30, for example, the connecting part 47 is in the shape of a disc, and the first fixing seat 44 and the second fixing seat 45 are arranged along the first direction and spaced apart from each other, the support shaft 41 is mounted on the support part 20 through the first fixing seat 44 and the second fixing seat 45, and the first fixing seat 44 and the second fixing seat 45 simultaneously support the support shaft 41, so that the support shaft 41 can stably rotate along the circumference.

[0080] For example, the motor 42 described above is a servo motor. When the motor 42 is working, it drives the support shaft 41 to rotate circumferentially, thereby the connecting part 47, which is fixedly connected to the support shaft 41, also rotates circumferentially. Then, the connecting part 47 drives the rotating disk 30, which is fixedly connected to it, to rotate circumferentially to a first position or a second position.

[0081] It should be noted that the specific type of the drive component 40 is not limited to this, and any structure capable of driving the support shaft 41 to rotate in the circumferential direction is within the protection scope of this application.

[0082] In some possible implementations, refer to Figure 1 , Figures 8 to 10 The imaging device 1 of this application further includes: a first mounting part 51, which is mounted on the rotating disk 30. The first mounting part 51 includes: a first recess 511, in which the first camera 50 is mounted; and a first screw mounting hole 512, which is provided on the outer surface of the first recess 511 and extends radially ( Figure 9 and Figure 10 The first camera 50 extends and penetrates the first recess 511 in the N direction and is radially perpendicular to the first direction; the first set screw (not shown) is located in the first screw mounting hole 512 and abuts against the outer surface of the first camera 50. By tightening the first set screw, the first set screw can drive the first camera 50 to translate radially along the bottom surface 5111 of the first recess 511; the first through hole 513 extends along the first direction and penetrates the bottom surface 5111 of the first recess 511 and communicates with the first recess 511. The first through hole 513 corresponds to the first imaging through hole 501 provided on the rotating disk 30. The first camera 50 takes pictures of the sample through the first imaging through hole 501.

[0083] Essentially, the first set screw can be used to adjust the radial position of the first camera 50, that is, adjust the shooting position of the first camera 50 in the first direction. This allows the first camera 50, after being installed in the first recess 511, to be aligned with the sample along the first direction through the first through hole 513 and the first shooting through hole 501, ensuring image quality. For example, if the first camera 50 is radially offset to the left from the sample when viewed from a top-down angle in the first direction after being installed in the first recess 511, then the first set screw can be operated to press against the outer surface of the first camera 50, driving the first camera 50 to translate radially to the right along the bottom surface 5111 of the first recess 511 until the first camera 50 is aligned with the sample in the first direction.

[0084] For example, there are at least two first screw mounting holes 512 arranged along the circumferential direction. Correspondingly, there are also at least two first set screws arranged along the circumferential direction. Figure 9The number of the first screw mounting holes 512 is four, and adjacent first screw mounting holes 512 are arranged at an interval of 90° in the circumferential direction. In this way, the first set screw not only plays a role in driving the first camera 50 to move in the radial direction, but also plays a role in fixing the first camera 50, and in addition, can adjust the radial position of the first camera 50 from multiple directions (front, back, left, right, etc.), so as to ensure that the first camera 50 can be aligned in the first direction to observe the sample.

[0085] In some possible embodiments, the photographing device 1 further comprises a second mounting portion (not shown in the figure) mounted on the rotating disc 30. The structure of the second mounting portion is the same as that of the first mounting portion 51, and specific descriptions can be referred to the above description of the structure of the first mounting portion 51. That is, the second mounting portion of the present application comprises a second recess (the structure is the same as that of the first recess 511), in which a second camera 60 is mounted; a second screw mounting hole (the structure is the same as that of the first screw mounting hole 512) arranged on the outer surface of the second recess, extending in the radial direction and penetrating through the second recess, and being perpendicular to the first direction in the radial direction; a second set screw (the structure is the same as that of the first set screw) arranged in the second screw mounting hole, abutting against the outer surface of the second camera 60, and capable of driving the second camera to translate in the radial direction on the bottom surface of the second recess by screwing the second set screw; and a second through hole (the structure is the same as that of the first through hole 513) extending in the first direction and communicating with the bottom surface of the second recess, corresponding to a second photographing through hole 601 arranged on the rotating disc 30, and through which the second camera 60 photographs the sample to be observed.

[0086] For example, the above-mentioned second screw mounting hole is at least two, arranged along the circumferential direction. Correspondingly, the second set screw is also at least two, arranged along the circumferential direction.
