On the contrary, the intention of implementing the novel features described in connection with the embodiments is to cover other alternatives or modifications which may be extended based on the claims of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be practiced without these particulars. Furthermore, some of the specific details are omitted from the description so as not to obscure or obscure the present invention. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 1 to 7, the present application provides a photographing apparatus 1 installed in a microscope. The photographing apparatus 1 includes: a main plate 10, a support portion 20, a driving assembly 40, and a rotation plate 30. Wherein the supporting portion 20 extends along a first direction (shown by a Z direction in fig. 1 to 3, 6 to 7), and the supporting portion 20 is vertically installed on the main board 10. Illustratively, the support 20 is plate-shaped. The driving unit 40 is mounted on the support 20 and has a support shaft 41 extending in a first direction. The rotating plate 30 is parallel to the main plate 10, and the rotating plate 30 is fixedly connected with the support shaft 41. Equivalently, the support shaft 41 is disposed perpendicularly to the rotating disk 30. The rotating disk 30 of the present application has a first camera 50 and a second camera 60 mounted thereon, and the first camera 50 and the second camera 60 are used to photograph an observation sample placed on a microscope for imaging analysis and study.

As shown in fig. 4, the rotating disk 30 is provided with a first photographing through hole 501 corresponding to the first camera 50, and a second photographing through hole 601 corresponding to the second camera 60. The first camera 50 photographs the observation sample through the first photographing through hole 501, and the second camera 60 photographs the observation sample through the second photographing through hole 601.

Illustratively, the "sample" as described above encompasses clinical samples, including, for example, cultured cells, cell supernatants, cell lysates, serum, plasma, biological fluids, tissue samples, and the like, as well as various precision devices, such as optical crystals, semiconductor devices, precision mechanical devices, and the like.

The drive assembly 40 of the present application is capable of driving the rotary disk 30 to rotate in a circumferential direction (indicated by direction T in fig. 3 and 5) by a first angle to a first position; alternatively, the driving assembly 40 can drive the rotating disk 30 to rotate in the circumferential direction by a second angle at the second position. In the first position, the first camera 50 is used to photograph an observation sample placed on the microscope; in the second position, the second camera 60 is used to photograph the observed sample. For example, in the first position and the second position, the main board 10 does not affect the first camera 50 and the second camera 60 to shoot the observation sample in the first direction.

Equivalently, the shooting device 1 of the present application provides two cameras, and switching of use of the first camera 50 and the second camera 60 is realized by switching the position (the first position or the second position) of the rotating disk 30 in the circumferential direction, so as to observe a sample through different cameras, thereby performing different imaging analyses and studies, and improving convenience of using a microscope and imaging analysis efficiency of a user.

Illustratively, 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 along the circumferential direction by a first angle to be located at the first position, the shooting device 1 is in the bright field imaging mode, bright field illumination imaging can be realized, and the observation sample is shot through the bright field camera (i.e. the first camera 50). When the driving assembly 40 drives the rotating disc 30 to rotate along the circumferential direction by a second angle to be located at the second position, the photographing apparatus 1 is in the fluorescence imaging mode, and fluorescence illumination imaging can be performed, and the observation sample is photographed by the fluorescence camera (i.e., the second camera 60). Thus, the photographing apparatus 1 of the present application can switch between the bright field imaging mode and the fluorescence imaging mode, and perform bright field illumination imaging and fluorescence illumination imaging, respectively.

In some possible embodiments, the driving assembly 40 can drive the rotating disc 30 to rotate from the initial position to the first position by a first angle in the circumferential forward direction, or to rotate to the second position by a second angle in the circumferential reverse direction. That is, the switching of the position of the rotating disk 30 in the circumferential direction is achieved by the forward rotation or reverse rotation of the drive assembly 40. This arrangement facilitates the accuracy with which the drive assembly 40 controls the rotation of the rotatable disk 30 in the circumferential direction.

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

In addition, the specific numerical values of the first angle and the second angle are not specifically limited, and are set correspondingly according to actual shooting requirements. For example, the first angle and the second angle are 15 °, 20 °, 30 °, and the like.

In some possible embodiments, referring to fig. 1, 3, 4, 6 and 7, the rotating disc 30 of the present application is provided with a first positioning member 31 and a second positioning member 32, and the main plate 10 is provided with a third positioning member 33 and a fourth positioning member 34.

When the driving assembly 40 drives the rotating disc 30 to rotate along the circumferential direction to be located at the first position, the first positioning member 31 and the third positioning member 33 are matched with each other to limit the movement of the rotating disc 30 in the circumferential direction, and when the driving assembly 40 drives the rotating disc 30 to rotate from the first position to the second position, 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 along the circumferential direction to be located at 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 when the driving assembly 40 drives the rotating disc 30 to rotate from the second position to the first position, the second positioning member 32 and the fourth positioning member 34 are separated.

That is, when the rotating disc 30 is located at the first position, the first positioning element 31 and the third positioning element 33 are matched with each other to play a role in positioning the rotating disc 30, and the first camera 50 can stably shoot and observe a sample, thereby improving the imaging quality. When the rotating disc 30 is located at the second position, the second positioning part 32 and the fourth positioning part 34 are matched with each other to play a role in positioning the rotating disc 30, and the second camera 60 can stably shoot and observe a sample, so that the imaging quality is improved.

Illustratively, the first positioning member 31 and the second positioning member 32 are spaced apart in the second direction (indicated by the X direction in fig. 5 and 7), and the third positioning member 33 and the fourth positioning member 34 are spaced apart in the second direction. Wherein the second direction is perpendicular to the first direction. The second direction is an extending direction of the main board 10.

Illustratively, one of the first positioning element 31 and the third positioning element 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 recess 381, and the other is a second bearing.

Specifically, in the present application, the first positioning element 31 and the second positioning element 32 are disposed on a portion of the rotating disc 30 facing the main board 10, the first positioning element 31 is a first groove, and the second positioning element 32 is a second groove; the third positioning element 33 and the fourth positioning element 34 are disposed on a portion of the main board 10 facing the rotating disk 30, the third positioning element 33 is a first bearing, the fourth positioning element 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 fixing rod 332 is sleeved with the first bearing, and the second fixing rod 341 is sleeved with the second bearing. Wherein, the portion of the main board 10 facing the rotating disk 30 is provided with a first fixed metal plate 331 and a second fixed metal plate 342. The first fixing rod 332 is mounted on the first fixing metal plate 331, and the first bearing can rotate around the first fixing rod 332; the second fixing rod 341 is mounted on the second fixing metal plate 342, and the second bearing can rotate around the second fixing rod 341.

When the driving assembly 40 drives the rotating disc 30 to rotate along the circumferential direction to be located at the first position, the first bearing is located in the first groove and plays a role in positioning the rotating disc 30 and limiting the movement of the rotating disc 30 in the circumferential direction. When the rotating disc 30 needs to be switched to be located at the second position, relative rotation occurs between the first bearing and the first groove, so that the first positioning piece 31 and the third positioning piece 33 are separated, and the rotating disc 30 can continue to move along the circumferential direction.

Similarly, when the driving assembly 40 drives the rotating disc 30 to rotate along the circumferential direction to the second position, the second bearing is located in the second groove, which plays a role in positioning the rotating disc 30 and limits the movement of the rotating disc 30 in the circumferential direction. When it is desired to switch the rotary plate 30 to the first position, relative rotation occurs between the second bearing and the second recess, such that the second positioning member 32 and the fourth positioning member 34 are separated and the rotary plate 30 can continue to move circumferentially.

Illustratively, when the rotary disk 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 photograph the observation sample.

In some possible embodiments, referring to fig. 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 limiting member 37 and a second limiting member 38. In the first position, the first limiting member 35 and the first limiting member 37 are engaged with each other, and the driving assembly 40 stops working; in the second position, the second position-limiting member 36 and the second position-limiting member 38 are engaged with each other, and the driving assembly 40 stops working. Wherein, the portion of the main board 10 facing the rotating disk 30 is provided with a third fixed metal plate 372 and a fourth fixed metal plate 382. The first stopper 37 is mounted on the third fixed sheet metal 372, and the second stopper 38 is mounted on the fourth fixed sheet metal 382.

That is, after the driving assembly 40 drives the rotating disc 30 to rotate by the first angle in the circumferential direction, the driving assembly 40 stops working. After the driving assembly 40 drives the rotating disc 30 to rotate along the circumferential direction by the second angle, the driving assembly 40 stops working. With this arrangement, the angle range of the rotation disk 30 in the circumferential direction is limited, and the driving assembly 40 is prevented from driving the rotation disk 30 to rotate in the circumferential direction without limitation, so that the photographing apparatus 1 is damaged, and the service life of the photographing apparatus 1 is prolonged. Meanwhile, the rotation accuracy of the rotating disk 30 rotating by the first angle or the second angle in the circumferential direction is improved, so that the switching of the position of the rotating disk 30 in the circumferential direction is accurately controlled, and the photographing apparatus 1 is accurately controlled to use the first camera 50 or the second camera 60. When the rotating disc 30 rotates to the first position or the second position along the circumferential direction, the driving assembly 40 stops working, which can prevent the rotating disc 30 from rotating continuously along the circumferential direction, and ensure that the rotating disc 30 is stably located at the first position or the second position, so that the first camera 50 and the second camera 60 can stably shoot and observe the sample.

Illustratively, the first and

second stoppers

37 and 38 are spaced apart in the second direction (shown by the X direction in fig. 5 and 7).

In some possible embodiments, the first limiting member 35 and the second limiting member 36 are sheet metal parts, and the first limiting member 37 and the second limiting member 38 are provided with grooves. The first limiting member 35 and the second limiting member 36 respectively have an extending portion extending along a first direction, when the rotating disc 30 is at the first position, the first limiting member 35 rotates along the circumferential direction until the extending portion thereof is located in the groove 371 of the first limiting member 37, and the driving assembly 40 stops working; when the rotating disc 30 is at the second position, the second limiting member 36 rotates circumferentially until its extension is located in the groove 381 of the second limiting member 38, and the driving assembly 40 stops working.

In some possible embodiments, referring to fig. 1 to 3 and 7, the shooting device 1 of the present application further includes: an encoder 70 attached to the main plate 10 and having an output shaft 70a extending in a first direction; a first synchronizing wheel 701 fixedly provided on the output shaft 70 a; a second synchronizing wheel 46 fixedly arranged on the supporting shaft 41; one end of the synchronous belt 702 is sleeved on the first synchronous wheel 701, and the other end thereof is sleeved on the second synchronous wheel 46. When the driving assembly 40 drives the supporting shaft 41 to rotate along the circumferential direction, the second synchronizing wheel 46 on the supporting shaft 41 rotates synchronously, so that the first synchronizing wheel 701 is driven to rotate through the timing belt 702, and the output shaft 70a fixedly connected with the first synchronizing wheel 701 also rotates along the circumferential direction. By providing the encoder 70, control of the angle of rotation of the support shaft 41 in the circumferential direction is achieved, and precise control of the angle of rotation (the first angle or the second angle) of the rotating disk 30 in the circumferential direction is achieved.

Illustratively, the through holes 301 on the rotating disk 30 are scallops. The drive assembly 40 of the present application further includes: the motor 42 is arranged at one end of the supporting part 20, which extends out of the through hole 301, through the motor supporting seat 43, and the motor supporting seat 43 is arranged at intervals with the rotating disc 30 along the first direction; equivalently, the rotating disk 30 is mounted on the shooting device 1 in a suspended manner; the supporting shaft 41 passes through the rotating disc 30 and is connected with a motor 42, and the motor 42 is used for driving the supporting shaft 41 to rotate along the circumferential direction; a connecting portion 47 protruding from the outer circumferential surface of the support shaft 41, the connecting portion 47 being located between the rotary disk 30 and the main plate 10, attached to a portion of the rotary disk 30 facing the main plate 10, and fixedly connected to the rotary disk 30, and exemplarily, the connecting portion 47 has a disk shape; the support shaft 41 is mounted on the support portion 20 through the first and second fixing seats 44 and 45 along the first and second fixing seats 44 and 45 disposed at an interval in the first direction, and the support shaft 41 is simultaneously supported by the first and second fixing seats 44 and 45, so that the support shaft 41 can be stably rotated in the circumferential direction.

Illustratively, the motor 42 is a servo motor. When the motor 42 is operated, the supporting shaft 41 is driven to rotate in the circumferential direction, so that the connecting portion 47 fixedly connected with the supporting shaft 41 also rotates in the circumferential direction, and then the connecting portion 47 drives the rotating disk 30 fixedly connected with the connecting portion to rotate in the circumferential direction to be located at the first position or the second position.

It should be noted that the specific type of the driving assembly 40 is not limited thereto, and the structure capable of driving the supporting shaft 41 to rotate along the circumferential direction is within the protection scope of the present application.

In some possible embodiments, referring to fig. 1, 8 to 10, the shooting device 1 of the present application further includes: and a first mounting part 51, the first mounting part 51 being mounted on the rotating disk 30. The first mounting portion 51 includes: a first recess 511, the first camera 50 being mounted in the first recess 511; a first screw mounting hole 512 provided on an outer surface of the first concave portion 511, extending in a radial direction (indicated by an N direction in fig. 9 and 10) and penetrating the first concave portion 511, the radial direction being perpendicular to the first direction; a first set screw (not shown) disposed in the first screw mounting hole 512, the first set screw abutting against an outer surface of the first camera 50, the first set screw being capable of driving the first camera 50 to translate in a radial direction on the bottom surface 5111 of the first concave portion 511 by screwing the first set screw; the first through hole 513 extends in the first direction, penetrates the bottom 5111 of the first concave portion 511, and communicates with the first concave portion 511, the first through hole 513 corresponds to the first photographing through hole 501 provided in the rotary disk 30, and the first camera 50 photographs the observation sample through the first photographing through hole 501.

For example, when the first camera 50 is mounted in the first concave portion 511, and the first camera 50 is deviated to the left in the radial direction from the observation sample in a top view in the first direction, the first set screw is operated to press against the outer surface of the first camera 50, and the first camera 50 is driven to translate to the right in the radial direction on the bottom surface 5111 of the first concave portion 511 until the first camera 50 is aligned with the observation sample in the first direction.
