Description

Technical Field

[0001] This utility model belongs to the technical field of gross imaging devices, specifically relating to a voice-controlled gross imaging device. Background Technology

[0002] During the collection of pathological specimens, it is necessary to periodically control the gross imaging system to perform actions such as magnification, reduction, focusing, and photography. In traditional gross imaging system control, foot pedal buttons or buttons on the main unit of the device are used for control.

[0003] The gross imaging system is controlled by pressing buttons on a foot pedal for zooming in, zooming out, focusing, and taking pictures. However, this system presents challenges for pathologists during specimen collection, as they must also keep an eye on the foot pedal. The foot is less sensitive than the hand, often leading to inaccurate control. Furthermore, foot pedals are typically wirelessly controlled, making them susceptible to signal blockage and interference, resulting in unresponsive operation. Finally, the mechanical button structure of the foot pedals is prone to damage from excessive pressing, affecting their normal use.

[0004] Traditional gross imaging systems rely on buttons on the device's main unit for zooming in, zooming out, focusing, and taking pictures. However, pressing these buttons during specimen collection can contaminate the equipment and cause cross-contamination of the specimens. Therefore, a non-contact gross imaging system is urgently needed. During specimen collection, the system requires frequent control to perform zooming, focusing, and taking pictures. Traditional gross imaging systems use foot pedals or buttons on the main unit for control. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the prior art by providing a voice-controlled gross imaging device, thereby solving the problems associated with using foot pedal buttons or buttons on the main unit of the device for control in existing gross imaging systems.

[0008] Furthermore, the camera is fixed on a mounting bracket, which is mounted on a base plate. The base plate is fixed inside the protective housing and has through holes.

[0009] Furthermore, the closed-loop motor is a stepper motor with an absolute encoder, which outputs a rotational angular displacement electrical signal and is fixed to the base plate by a motor bracket.

[0010] Furthermore, the light source module includes a ring-shaped LED light panel, a diffuser plate, a ring-shaped polarizer, and a circular polarizer; The annular LED light panel is connected to a heat sink, which is installed below the base plate. A diffuser is provided at the rear end of the annular LED light panel.

[0020] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0021] The voice-controlled general imaging device of this embodiment can realize the magnification, reduction, and focusing of the general image, as well as the opening and closing of the light source and the adjustment of brightness through voice control. (Refer to...) Figure 1 and Figure 2 Specifically, it includes: Shooting device 1, light source module 2, drive control module 3, and protective housing 4; In some embodiments, the shooting device 1, the light source module 2, and the drive control module 3 are all housed within the protective housing 4, with the light source module 2 positioned directly below the shooting device 1 to provide illumination. The drive control module 3 drives the shooting device 1 to rotate at a fixed angular displacement and controls the switching and brightness adjustment of the light source module 2.

[0022] In one specific embodiment, the shooting device 1 includes a shooting camera 5, a base plate 6, a mounting bracket 7, a zoom lens 8, a zoom ring 9, a closed-loop motor 10, a drive gear 11, and a motor bracket 12. The camera 5 is fixed on the mounting bracket 7, the mounting bracket 7 is installed on the base plate 6, the base plate 6 is fixed inside the protective housing 4, and the base plate 6 has a through hole; the front end of the camera 5 is provided with a slot, the zoom lens 8 is screwed into the slot and fixed, and the zoom ring 9 on the camera 5 is made of deformable material, and its inner hole and the outer contour of the zoom lens 8 are connected by an interference fit tension. The closed-loop motor 10 is a stepper motor with an absolute encoder, which can output a rotational angular displacement electrical signal. It is fixed on the base plate 6 by the motor bracket 12. The output shaft end of the closed-loop motor 10 is fixedly connected to the drive gear 11. The outer end face of the zoom ring 9 is designed as a gear structure. In actual operation, the drive gear 11 meshes with the zoom ring 9 to control the rotation of the closed-loop motor 10, thereby driving the zoom lens 8 to achieve precise zoom.

[0023] In some embodiments, reference Figure 3 The light source module 2 includes a heat sink 13, a ring LED light board 14, a diffuser 15, a ring polarizer 16, and a circular polarizer 17. In one specific embodiment, the annular LED light panel 14 is designed with a plurality of LEDs evenly distributed on an aluminum substrate. The annular LED light panel 14 and the heat sink 13 are bonded together using thermally conductive adhesive. The heat sink 13 is installed below the base plate 6. A diffuser 15 is provided at the rear end of the annular LED light panel 14 to make the lighting source diffuse evenly. An annular polarizer 16 is provided at the rear end of the diffuser 15 to convert the light from the annular LED light 14 into polarized light. A circular polarizer 17 is rotatably mounted on the base plate 6 and located below the zoom lens 8 (i.e., a circular polarizer 17 is provided at the front end of the zoom lens 8).

[0024] The circular polarizer 17 is mounted on the rotating device. By rotating the circular polarizer 17, its grating direction is made perpendicular to the polarization direction of the light reflected by the water droplet, thereby blocking the reflected light and retaining the projected light, thus achieving the effect of eliminating water droplet reflection. At the same time, it achieves a sealing effect to prevent dust and water droplets from splashing into the equipment during use and causing equipment failure.

[0025] Specifically, the rotating device includes a knurled rotating plate 171, a rotating plate connector 172, a rotating limit seat 173, and a circular polarizer 17 fixed on the knurled rotating plate 171. The rotating limit seat 173 is designed with a circular hole that is clearance-fitted with the circular groove of the rotating knurled plate 171, allowing it to rotate circumferentially around the circular hole. The rotating plate connector 172 passes through the circular groove of the rotating limit seat 173 and is threadedly connected to the knurled rotating plate 171, preventing the knurled rotating plate 171 from falling off the circular hole of the rotating limit seat 173.

[0026] In some embodiments, reference Figure 2The drive control module 3 includes a drive control board 18 and a voice receiver 19; the voice receiver 19 is embedded in a pre-reserved groove on the protective housing 4 and receives voice commands; the drive control board 18 is signal-connected to the voice receiver 19 and electrically connected to the closed-loop motor 10.

[0027] Among them, the voice receiving device 19 is an electret MIC-6027.

[0028] The drive control board 18 is a controller developed for the STM32F103VET6 microcontroller.

[0029] During actual operation, the voice receiving device 19 receives voice commands and pre-stores the operation program and control voice commands in the drive control board 18, using "magnification commands," "light source adjustment commands," and "focus and photograph commands." For example, during the material collection process, by using a magnification command (such as "0.5×n"), the drive control board executes the set program, controlling the closed-loop motor 10 to rotate by a fixed angular displacement. The shaft of the closed-loop motor 10 drives the active gear 11 to rotate by a fixed angular displacement, which in turn drives the zoom ring 9 to rotate by a fixed angular displacement to achieve fixed magnification. The closed-loop motor 10 has a built-in encoder that can set the motor's rotation limit angle to avoid lens collision. By using light source switch commands (such as "on / off" light source, brightness "percentage" times), the ring light source is controlled to switch on and off and adjust its brightness. By using focus and photograph commands (such as "focus / photograph"), the shooting device is controlled to perform focus / photograph operations. The operator does not need to touch the equipment itself, preventing soiling or affecting the sample. The operator uses voice commands while collecting materials, which does not interfere with the material collection process, thus improving work efficiency.

[0030] It should be noted that the voice control commands in this embodiment are merely driving commands for the entire device, and its core remains a mechanical structure.

[0031] In some embodiments, reference Figure 4 The protective housing 4 includes a housing 20 and a bottom cover 21. The bottom cover 21 is located at the bottom of the housing 20, and handles 22 are respectively provided on the two opposite sides of the housing.

[0032] In one specific embodiment, the bottom cover 21 is designed as an annular groove for placing the diffuser plate 15 and the annular polarizer 16. Soft silicone is used to fill the edge gaps to fix and seal the device. Handles 22 are respectively installed on the left and right sides of the housing 20 to facilitate the handling and movement of the equipment. The housing 20 is fixedly connected to the base plate 6, and then the bottom cover 21 is fixedly connected to the base plate 6 to form a closed state, which effectively prevents dust and water droplet splashes.

[0033] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
