[0002] An insect specimen loading device is a device for fixing an insect specimen when observing the insect specimen under a microscope. This device is composed of a loading base and a loading arm. When in use, the loading base is placed on a flat plane, then the insect specimen is fixed on the loading arm, and then the whole is placed under the microscope for observation. If shooting is required, the loading arm needs to be manually rotated to rotate the insect specimen, but the fixed scale cannot be rotated, so that 360-degree shooting of the insect specimen cannot be achieved. Application (patent) number: CN202011441185.1 discloses a "method, system, device and medium for photographing a specimen image with a microscope", in which the microscope includes a high-precision stage and an imaging system that can move vertically in the z direction or move in three directions of x, y, and z. This structure is that the imaging system moves three-dimensionally, with a complex structure and it is difficult to photograph the bottom surface of the insect specimen. Application (patent) number: CN201710128619.4 discloses a "microscope photographing auxiliary device", which includes a base, two second columns are arranged on the base, the second columns are arranged in parallel, the top of each second column is connected to a first column through a height adjusting mechanism, a baffle is arranged at the top of the first column, a bracket is arranged on the baffle, the baffle is arranged at the bottom of the bracket, the baffle and the bracket are perpendicular to each other, and the baffle is connected to an angle adjusting mechanism. The material of this device is metal or hard plastic, with low cost, light weight and easy to place, occupying less space, and can be compatible with various brands and models of microscopes and photographing devices such as mobile phones, cameras, and small video cameras at the same time; this device is easy to operate, can adjust the height, angle and shooting distance, the shooting effect is stable, the image is clear, complete and accurate, and the length can be quantified by using the field of view diameter distance in the captured image, saving the shooting time, reducing the shooting difficulty, and improving the shooting efficiency. The disadvantage of this structure is that in order to perform 360-degree shooting of the insect specimen, the "microscope photographing auxiliary device" must move at multiple angles. Summary of the Invention

[0003] The purpose of the utility model is to provide a loading device for insect specimens used for microscope photographing. By rotating the scale indicating needle, the insect specimen carrier can be rotated by a certain angle and displayed on the 360-degree circular scale disk, so as to achieve shooting at any angle within 360 degrees of the insect specimen.

[0004] The object of the present utility model is achieved as follows. An insect specimen loading device for microscope shooting includes a loading arm, a loading base, and an insect specimen loading body. The loading base is placed under the shooting lens of the microscope. It is characterized in that a 360-degree circular scale disk is fixed on the loading base. A circular groove is provided on the loading base below the shooting lens of the microscope. An annular photographing illuminating lamp is arranged in the circular groove for illuminating the insect specimen loading body. The annular photographing illuminating lamp is connected to a power source and can be turned on and off through a switch arranged on the loading base. The circular groove enables the insect specimen loading body to rotate without obstruction. One end of the loading arm is detachably connected to the insect specimen loading body above the circular groove. The other end of the loading arm passes through the loading arm positioning base fixed on the loading base and the central hole of the 360-degree circular scale disk and is fixedly connected to a rotating handle. The loading arm is rotatably connected to the loading arm positioning base and the central hole of the 360-degree circular scale disk through bearings, so that the loading arm is supported in the loading arm positioning base through the bearings and can rotate flexibly, and the loading arm is supported in the central hole of the 360-degree circular scale disk through the bearings and can rotate flexibly. A scale indicating needle is fixed on the loading arm on one side of the scale line of the 360-degree circular scale disk. By rotating the rotating handle to drive the loading arm to rotate, the scale indicating needle rotates together. The scale indicating needle shows the required rotation angle on the scale line of the 360-degree circular scale disk, so that the insect specimen loading body linked to the loading arm rotates to the required angle, and any angle within 360 degrees of the insect specimen can be shot through microscope shooting.

[0005] Furthermore, a driven gear is fixed on the loading arm. The central hole of the driven gear is sleeved outside the loading arm and fixed on the loading arm. A driving gear meshes with the driven gear. The motor shaft of a motor passes through the central hole of the driving gear and its extension section is fixedly connected to the input shaft of an angle sensor through a connecting sleeve. The output end of the angle sensor is electrically connected to the angle signal input end of a central processor. The control signal output end of the central processor is electrically connected to the driving signal input end of the motor. The central processor is electrically connected to a terminal, and the terminal is a computer or a mobile phone.

Detailed implementation mode

[0014] The present utility model will be described in detail below with reference to the accompanying drawings and embodiments: Embodiment 1

[0015] As Figure 1 and Figure 3 shown, a loading device for an insect specimen for microscope photographing includes a loading arm 2, a loading base 3, and an insect specimen loading body 4. The loading base 3 is placed under the photographing lens of the microscope 1. Its structural feature is that: the 360-degree circumferential scale disk 5 is fixed on the loading base 3. A circular groove 6 is provided on the loading base located under the photographing lens of the microscope. An annular photographing illuminating lamp 7 can also be arranged in the circular groove for illuminating the insect specimen loading body (see Figure 2), the circular groove facilitates the light collection of the annular photographing illumination lamp. The annular photographing illumination lamp is connected to a power source and can be turned on and off through a switch 8 provided on the loading base. One end of the loading arm 2 is detachably connected to the insect specimen carrier 4 located above the circular groove 6 (this facilitates the replacement of other insect specimen carriers). The circular groove 6 enables the insect specimen carrier 4 to rotate unobstructed (that is, the insect specimen carrier can be suspended or partially placed into the circular groove and rotate 360 degrees unobstructed. The circular groove does not block the rotation of the insect specimen carrier). The other end of the loading arm 2 passes through the loading arm positioning base 9 fixed to the loading base (at this time, the central hole of the loading arm positioning base facilitates the passage of the other end of the loading arm) and the central hole of the 360-degree circular scale 5 and is fixedly connected to a rotating handle 10. The loading arm 2 is rotatably connected to the central holes of the loading arm positioning base 9 and the 360-degree circular scale 5 it passes through through bearings, so that the loading arm is supported in the loading arm positioning base by bearings and can rotate flexibly 360 degrees. Moreover, the loading arm is also supported in the central hole of the 360-degree circular scale by bearings and can rotate flexibly 360 degrees. The scale indicating needle 11 is fixed on the loading arm on one side of the scale line of the 360-degree circular scale 5. By rotating the rotating handle 10, the loading arm is driven to rotate, and the scale indicating needle connected to the loading arm rotates together. The scale indicating needle shows the required rotation angle on the scale line of the 360-degree circular scale. The rotation of the loading arm makes the insect specimen carrier connected to the loading arm rotate synchronously and can rotate to the same angle as the angle recorded by the scale line shown on the 360-degree circular scale. At this time, photographing is carried out through the microscope. When photographing, the annular photographing illumination lamp in the circular groove can be turned on, and the insect specimen carrier connected to the loading arm is continuously rotated to achieve photographing at any angle within 360 degrees of the insect specimen.

[0016] Embodiment 2 (with an example of electric rotation)

[0017] As Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, an insect specimen loading device for microscope photographing includes a loading arm 2, a loading base 3, and an insect specimen carrier 4. The loading base is placed under the photographing lens of the microscope 1. Its structural features are: a 360-degree circular scale is fixed on the loading base. A circular groove 6 is provided on the loading base under the photographing lens of the microscope. An annular photographing illumination lamp 7 can also be arranged in the circular groove for illuminating the insect specimen carrier (see Figure 2),(The circular groove facilitates the light collection of the annular photographing illumination lamp. The annular photographing illumination lamp is connected to a power source and can be turned on and off through a switch 8 provided on the loading base. One end of the loading arm 2 is detachably connected to the insect specimen carrier located above the circular groove (this facilitates the replacement of other insect specimen carriers). The circular groove enables the insect specimen carrier to rotate unobstructed (that is, the insect specimen carrier can be suspended or partially placed into the circular groove 6 and rotate 360 degrees in a circle without obstruction). The other end of the loading arm 2 passes through the loading arm positioning base 9 fixed to the loading base (at this time, the central hole of the loading arm positioning base facilitates the passage of the other end of the loading arm) and the central hole of the 360-degree circular scale 5 and is fixedly connected to a rotating handle 10. The loading arm is rotatably connected to the central holes of the loading arm positioning base it passes through and the central hole of the 360-degree circular scale through bearings, so that the loading arm is supported in the loading arm positioning base 9 by bearings and can rotate flexibly 360 degrees. Moreover, it also enables the loading arm to be supported in the central hole of the 360-degree circular scale by bearings and can rotate flexibly 360 degrees. The scale indicating needle 11 is fixed on the loading arm on one side of the scale line of the 360-degree circular scale. A driven gear 12 is fixed on the loading arm. The central hole of the driven gear is sleeved outside the loading arm and fixed on the loading arm. A driving gear 13 meshes with the driven gear (see Figure 4, which is a structural schematic diagram. In actual application, different transmission ratios are achieved through the cooperation of gears with different diameters, so as to meet the needs of the present utility model in various situations and can be realized by those of ordinary skill in the art. The motor shaft of a motor 14 passes through the central hole of the driving gear, and its extending section is fixedly connected with the input shaft of an angle sensor 15 through a connecting sleeve (the angle sensor can be fixed on a 360-degree circular scale plate or on the loading base, or fixed independently. One end of the connecting sleeve is fixedly connected with the extending section, and the other end is fixedly connected with the input shaft, that is, the connecting sleeve and the input shaft of the angle sensor or the extending section of the motor shaft are fixedly connected through a pin shaft), so that the rotation angle information of the loading arm can be transmitted to the angle sensor. The output end of the angle sensor is electrically connected to the angle signal input end of the central processor, and the control signal output end of the central processor is electrically connected to the drive signal input end of the motor; The central processor can also be electrically connected to a terminal, and the terminal can be a computer or a mobile phone. In this way, the present utility model can control or monitor the rotation angle through the computer or the mobile phone via the central processor. When it is necessary to adjust the angle of the insect specimen loading object to be photographed, people can issue commands (such as commands for 30-degree angle or 45-degree angle, etc.) through the terminal. The motor rotates under the control of the central processor. The driving gear rotates when the motor rotates, and the driven gear meshing with it also rotates synchronously. The rotation of the driven gear drives the loading arm to rotate, so that the scale indicating needle connected to the loading arm rotates together. The scale line on the 360-degree circular scale plate shows the required rotation angle (such as 30-degree angle or 45-degree angle, etc.). The rotation of the loading arm makes the insect specimen loading object connected to the loading arm rotate synchronously and can rotate to the same angle as recorded by the scale line shown on the 360-degree circular scale plate (such as 30-degree angle or 45-degree angle, etc.). At this time, photographing is carried out through the microscope. When taking pictures, the annular photographing illuminating lamp in the circular groove can be turned on, and the insect specimen loading object connected to the loading arm is continuously rotated to realize photographing at any angle within 360 degrees of the insect specimen.

[0018] Preferably, for the present utility model, it can be set that when the driven gear rotates one tooth, the scale indicating needle rotates 0.1 degree. If the driven gear has 3,600 teeth, then when the driven gear rotates one circle, it is 360 degrees. It can be set that the driving gear is the same as the driven gear, that is, the condition for a pair of gears to be correctly meshed is that they must have the same module and the same pressure angle. At this time, the motor can be controlled by the central processing unit to rotate. When the driving gear rotates one circle, the driven gear also rotates one circle, and the scale indicating needle on the load arm rotates 360 degrees. In this way, when the scale indicating needle on the load arm rotates 360 degrees, it can be displayed through the 360-degree circumferential scale disk and the terminal connected to the central processing unit, that is, displayed through a mobile phone or a computer. Of course, when the requirement for rotation accuracy is not very precise, it can be set that when the driven gear rotates one tooth, the scale indicating needle rotates 1 degree. If the driven gear has 360 teeth, then when the driven gear rotates one circle, it is 360 degrees. It can be set that the driving gear is the same as the driven gear, that is, the condition for a pair of gears to be correctly meshed is that they must have the same module and the same pressure angle. When the driving gear rotates one circle, the driven gear also rotates one circle, and the scale indicating needle on the load arm rotates 360 degrees, and it can be displayed on the computer or the mobile phone. Of course, it can also be set in other ways implemented by those skilled in the art. For example, for the driven gear and the driving gear, if the diameter size, the number of teeth, etc. are in a set ratio, the purpose of the present utility model can also be achieved.

[0019] The angle sensor of the present utility model adopts an angle sensor with a measurement range of 0 - 359°, and the output signal is in the form of 4 - 20Ma analog general signal data, which is convenient for signal processing and display with other devices, and meets the data transmission and sharing between devices. The motor is preferably a servo motor. Embodiment 3

[0020] As Figure 2 、 Figure 3 、 Figure 4 and Figure 6 shown, an insect specimen loading device for microscope shooting includes a load arm 2, a load base 3, and an insect specimen carrier 4. The load base is placed under the shooting lens of the microscope 1. Its structural feature is that a 360-degree circumferential scale disk is fixed on the load base. A circular groove 6 is provided on the load base under the shooting lens of the microscope. An annular photographing illumination lamp 7 can also be arranged in the circular groove for illuminating the insect specimen carrier (see Figure 2), the circular groove facilitates the light collection of the annular photographing illumination lamp. The annular photographing illumination lamp is connected to a power source and can be turned on and off through a switch 8 provided on the loading base. One end of the loading arm 2 is detachably connected to the insect specimen carrier located above the circular groove (this facilitates the replacement of other insect specimen carriers). The circular groove enables the insect specimen carrier to rotate unobstructed (i.e., the insect specimen carrier can be suspended or partially placed into the circular groove 6 and rotate 360 degrees in a circle without obstruction). The other end of the loading arm 2 passes through the loading arm positioning base 9 fixed to the loading base (at this time, the central hole of the loading arm positioning base facilitates the passage of the other end of the loading arm) and the central hole of the 360-degree circular scale 5 and is fixedly connected to a rotating handle 10. The loading arm is rotatably connected to the central holes of the loading arm positioning base and the 360-degree circular scale through bearings, so that the loading arm is supported in the loading arm positioning base 9 by bearings and can rotate flexibly 360 degrees, and also enables the loading arm to be supported in the central hole of the 360-degree circular scale by bearings and can rotate flexibly 360 degrees. The scale indicating needle 11 is fixed on the loading arm on one side of the scale line of the 360-degree circular scale. A driven gear 12 is fixed on the loading arm. The central hole of the driven gear is sleeved outside the loading arm and fixed on the loading arm. A driving gear 13 meshes with the driven gear (see Figure 4, which is a structural schematic diagram. In actual application, different transmission ratios are achieved through the cooperation of gears with different diameters, so as to meet the needs of the present utility model in various situations, which is a technology that can be achieved by ordinary technicians. The motor shaft of a motor 14 passes through the central hole of the driving gear, and its extension section is fixedly connected to the input shaft of an angle sensor 15 through a connecting sleeve (the angle sensor can be fixed on a 360-degree circular scale disk or on the load-carrying base, or fixed independently. One end of the connecting sleeve is fixed to the extension section, and the other end is fixed to the input shaft, that is, the connecting sleeve and the input shaft of the angle sensor or the extension section of the motor shaft are fixedly connected through a pin shaft), so that the rotation angle information of the load-carrying arm can be transmitted to the angle sensor, and the output end of the angle sensor is electrically connected to the angle signal input end of the central processor; the central processor can also be electrically connected to a terminal, and the terminal can be a computer or a mobile phone, so that remote control or monitoring of the rotation angle can be carried out through the computer or the mobile phone via the central processor. When it is necessary to adjust the angle of the insect specimen carrier to be photographed, people can issue a command through the terminal, control the motor to rotate through the central processor, the motor rotates, the driving gear rotates, and the driven gear meshed therewith also rotates synchronously. The rotation of the driven gear drives the load-carrying arm to rotate, causing the scale indicating needle connected to the load-carrying arm to rotate together. The scale indicating needle shows the required rotation angle on the scale line of the 360-degree circular scale disk. The rotation of the load-carrying arm causes the insect specimen carrier connected to the load-carrying arm to rotate synchronously, and can rotate to the same angle as recorded by the scale line shown on the 360-degree circular scale disk. At this time, photographing is carried out through the microscope. When taking a photo, the annular photographing lighting lamp in the circular groove can be turned on, and the insect specimen carrier connected to the load-carrying arm is continuously rotated to achieve 360-degree photographing of the insect specimen.

[0021] Preferably, for the present utility model, it can be set that when the driven gear rotates one tooth, the scale indicating needle rotates 0.1 degree. If the driven gear has 3,600 teeth, then when the driven gear rotates one circle, it is 360 degrees. It can be set that the driving gear is the same as the driven gear. That is, the condition for a pair of gears to be correctly meshed is that they must have equal module and equal pressure angle. At this time, the motor rotation can be controlled by the central processing unit. When the driving gear rotates one circle, the driven gear also rotates one circle, and the scale indicating needle on the load arm rotates 360 degrees. In this way, when the scale indicating needle on the load arm rotates 360 degrees, it can be displayed through the 360-degree circumferential scale disk and the terminal electrically connected to the central processing unit, that is, displayed through a mobile phone or a computer. Of course, when the requirement for rotation accuracy is not very precise, it can be set that when the driven gear rotates one tooth, the scale indicating needle rotates 1 degree. If the driven gear has 360 teeth, then when the driven gear rotates one circle, it is 360 degrees. It can be set that the driving gear is the same as the driven gear. That is, the condition for a pair of gears to be correctly meshed is that they must have equal module and equal pressure angle. When the driving gear rotates one circle, the driven gear also rotates one circle, and the scale indicating needle on the load arm rotates 360 degrees, then it can be displayed through the 360-degree circumferential scale disk and displayed on a computer or a mobile phone. Of course, it can also be set in other ways implemented by those skilled in the art. For example, for the driven gear and the driving gear, the number of large and small teeth, etc. are in a set ratio, then the purpose of the present utility model can also be achieved.

[0022] The angle sensor of the present utility model adopts an angle sensor with a measurement range of 0 - 359°, and the output signal is in the form of 4 - 20Ma analog general signal data, which is convenient for signal processing and display with other devices, and meets the data transmission and sharing between devices. The motor is preferably a servo motor.

[0023] In this embodiment, the utility model can be used in conjunction with the application (patent) number: CN202110637316.1, that is, the camera of the utility model (the camera is preferably autofocus) is connected to the microscope for taking images observed by the microscope; an image quality detection device is used to connect to the camera, control the shooting of the camera, receive the images taken by the camera, and detect the defocus measure value and brightness of the images. The image quality detection device includes: a camera driving circuit connected to the camera for driving the camera, an image transmission circuit connected to the camera driving circuit for collecting the images taken by the camera, preprocessing the images and transmitting them to the central controller and then to the image quality detection device, and a central controller respectively connected to the camera and the camera driving circuit for calculating the defocus measure value according to the images taken by the camera at different heights of the microscope from the insect specimen stage, sending the defocus measure value to the central controller via the image transmission circuit so that the main controller controls the zoom of the camera according to the defocus measure value; and for calculating the brightness and complexity of the images taken by the camera, sending the brightness and complexity to the central controller via the image transmission circuit so that the central controller controls the annular photographing illumination lamp according to the brightness and complexity; the central controller is respectively connected to the image quality detection device, the camera and the motor for receiving the defocus measure value and brightness of the image quality detection device to control the zoom of the camera, the rotation of the motor, and an image analysis device connected to the central processor for receiving the images transmitted by the image quality detection device, stitching and analyzing the images; the display device is used to display the results judged by the central processor and display the images.

[0024] The central processor controls the programmable LED array circuit (when the annular photographing illumination lamp uses a programmable LED array circuit) to display the required light intensity through the COM1 communication port; the image quality detection device provides a trigger signal to trigger the camera to work through a level conversion chip. In the LED array circuit driving data protocol, the main controller sends control instructions to the LED array circuit through the COM1 communication port to control its working state, so that it outputs different working mode signals to the programmable LED array display. The working modes can include: dark light mode, strong light mode, light field mode, differential imaging mode, custom mode. In the custom mode, the light intensity can be changed in multiple levels.

[0025] For the first low-magnification image captured by the camera, the first defocus measure value is calculated using a defocus measure function, which is the gray variance function of the gray gradient operator, i.e., the second-order partial derivative is taken in the XY directions. For the second low-magnification image captured by the camera, the second defocus measure value is calculated using the defocus measure function. If the first defocus measure value is less than the second defocus measure value, the camera continues to zoom, and low-magnification images are continuously acquired. The defocus measure value of each obtained low-magnification image is compared with the previous one until the defocus measure value obtained by a certain camera zoom is greater than the defocus measure value obtained by the subsequent camera zoom, at which point the camera is fixed to end the focusing process.

[0026] It can be understood that in addition to using the gray variance function, the defocus measure function can also be implemented using the Brenner gradient function, Tenengrad gradient function, Laplacian gradient function, variance function, energy gradient function, entropy function, and Vollath function.

[0027] The complexity of the image is calculated using the weighted average of the absolute value of the difference between the luminance value of the pixels in the low-magnification image and the average luminance value of the low-magnification image.

[0028] The human eye is more sensitive to image quality degradation on low-frequency images than on high-frequency images. At the same time, images with high complexity have high spatial frequencies, and the human eye is less likely to detect image quality degradation. Regarding luminance, the human eye is more likely to detect image quality degradation in dark regions and less likely to detect image quality degradation in bright regions. Therefore, the purpose of setting the first threshold and the second threshold is to adjust the light source luminance while considering the sensitivity of the human eye to image luminance and complexity, making the imaging clearer.

[0029] The image analysis device stitches and analyzes all the low-magnification images transmitted by the central processing unit and processes them through a computer.
