Description

Technical Field

[0001] The utility model belongs to the technical field related to scanning instruments, and in particular relates to a tracking device and a tracking scanner. Background Art

[0002] The tracking device is a key component of a tracking scanner. During operation, heat generated by the tracking device is primarily concentrated in the chip, main control board, and LED light board. Currently, existing tracking devices typically dissipate heat through passive natural cooling. This involves attaching thermal pads to heat-concentrating components on the tracking device. These pads transfer the heat generated by these components to a finned aluminum alloy heat sink, which then cools naturally in the air.

[0003] Currently, the chips in existing tracking devices are generally fixed to the frame using fixings such as locating pins and screws, and then sealed with sealant. The pixel sensor and pixel regulator used on the chip are the main heat sources. This heat is transferred to the extended section of the frame and the lens barrel through the connection with the frame. The presence of this heat will cause the aluminum frame and barrel to expand and contract during the thermal equilibrium process, causing fluctuations in the intrinsic and extrinsic parameter coefficients. With the update and iteration of equipment, the camera's pixels, communication transmission speed, data processing speed and other factors are constantly improving, and the problem of heating of the entire device is becoming more and more prominent. The existing solution of using the device itself as a heat dissipation medium cannot meet the requirements of device reliability and temperature compensation consistency. Therefore, it is necessary to improve the heat dissipation method to further enhance the heat dissipation capacity. Utility Model Content

[0017] In one embodiment, a guide plate is installed in the air guide cover, the guide plate is arranged in the air duct, and the guide plate is used to guide the flow of the air in the air duct.

On the one hand, it can reduce the energy loss during air flow and improve the heat dissipation efficiency of the tracking device when it is working. On the other hand, it can also reduce the noise generated by the air cooling of the tracking device and improve the product quality of the tracking device.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] like Figures 1 to 4As shown, a tracking device 100 provided in one embodiment of the present application includes a tracking device body 10 and an air guide hood 20. The air guide hood 20 is mounted on the tracking device body 10. An air duct 201 is formed inwardly of the air guide hood 20, and a fan 30 is installed in the air duct 201. When the fan 30 is in operation, it can drive air to flow in the air duct 201 to dissipate heat from the tracking device body 10. In other words, when the tracking device 100 is in operation, it can dissipate heat from the tracking device body 10 through active air cooling. This improves the heat dissipation efficiency of the tracking device 100 during operation, meeting the reliability and temperature compensation consistency requirements of the components in the tracking device 100, thereby ensuring the scanning accuracy of the tracking scanner using the tracking device 100. Here, the aforementioned components include but are not limited to the frame 11, the camera module 12, and the main control board 13.

[0042] It should be noted that during the development and commissioning of the tracking device 100, it was discovered that temperature significantly affects scanning accuracy. With the continuous advancement of tracking scanner equipment, more stringent requirements have been placed on factors such as image quality, communication methods, data transmission, and processing speed. Accordingly, the heat generated by the tracking device 100 during operation has also continued to rise. The main heat generation components of the tracking device 100 are the image acquisition and processing module, the communication module, and the fill light module. The image acquisition and processing module has two main functions: first, capturing target features: capturing characteristic information on the surface of the scanned object or its surroundings, such as markers, textures, and geometric shapes, to provide the data foundation for tracking and positioning; and second, determining the position of the scanning head: analyzing and processing the captured images to accurately calculate the position and attitude changes of the scanning head relative to the scanned object or reference coordinate system. The main heat-generating components of the image acquisition and processing module are the camera's image processor, the FPGA / SOC used for calculation and processing, the data storage, and other chips and inductors on the PCB. The communication module primarily functions for data transmission. As the data transmission between the scanning and tracking devices transitions from wired to wireless, heat generation has also increased. The main function of the fill light module is to improve the light changes in front of the camera.

[0043] like Figures 1 to 3 As shown, the tracking device body 10 includes a skeleton 11, two camera modules 12, and a main control board 13. The two camera modules 12 are installed on the skeleton 11. Each camera module 12 includes a radiator 121, which is used to dissipate heat during operation of the camera module 12. The main control board 13 is used to control the operation of the tracking device body 10.

[0044] like Figures 1 to 3 As shown, the air guide cover 20 is fixedly connected to the frame 11 , and the air guide cover 20 is assembled and connected to the tracking device body 10 .

[0045] Preferably, the air scoop 20 is detachably connected to the tracking device body 10. This allows the tracking device 100 to be disassembled and assembled according to usage requirements to meet the heat dissipation requirements of the tracking device 100 during operation. When the fan 30 malfunctions, the air scoop 20 can be removed from the frame 11 before repairing or replacing the fan 30. This facilitates subsequent maintenance or replacement of the fan 30 on the air scoop 20. The air scoop 20 can be secured to the frame 11 using clips, screws, bolts, or the like.

[0046] like Figures 2 to 4 As shown, the radiator 121 partially extends into the air duct 201, so that the air flowing in the air duct 201 of the air guide cover 20 can dissipate heat from the radiator 121 on the camera module 12, thereby achieving efficient heat dissipation of the camera module 12. It should be noted that the radiator 121 on the camera module 12 can adopt a conventional method in existing tracking devices, which will not be elaborated here.

[0047] like Figures 1 to 3 As shown, the air guide cover 20 is provided with an air inlet 21 in the area where each radiator 121 is located, and the air inlet 21 is connected to the air duct 201. When the tracking device 100 is working, the ambient air can be introduced into the air duct 201 of the air guide cover 20 through the air inlet 21, so that the relatively low-temperature air introduced by the air inlet 21 can be directly blown to the radiator 121, which can further improve the heat dissipation efficiency of the camera module 12. Here, the air guide cover 20 is provided with an air outlet 22 in the area where the fan 30 is located, and the air outlet 22 is connected to the air duct 201. When the fan 30 is working, the fan 30 draws air from the air outlet 22 and makes the internal environment of the air duct 201 of the air guide cover 20 negative pressure, so that the ambient air can be introduced through the air inlet 21 on the air guide cover 20 and realize the flow of air in the air duct 201.

[0048] As preferably, Figures 1 to 3 As shown, the number of air inlet holes 21 is configured to be multiple, and the multiple air inlet holes 21 are arranged along the circumferential direction of the radiator 121. When the fan 30 is operating, relatively low-temperature air in the environment can enter the air duct 201 of the air guide cover 20 from the circumferential direction of the radiator 121. This allows the low-temperature air to fully contact the radiator 121, thereby further improving the heat dissipation efficiency of the camera module 12. Here, the air guide cover 20 is evenly provided with multiple air inlet holes 21 on three sides of the area where the radiator 121 is located.

[0049] like Figure 4As shown, a deflector 23 is installed in the air guide cover 20. The deflector 23 is arranged in the air duct 201 and is used to guide the flow of air in the air duct 201 to achieve the purpose of guiding the air. This can optimize the air flow field. On the one hand, it can reduce energy loss during air flow and improve the heat dissipation efficiency of the tracking device 100 during operation. On the other hand, it can also reduce the noise generated by the air cooling of the tracking device 100 and improve the product quality of the tracking device 100. Here, the deflector 23 is arranged between the radiator 121 and the fan 30, so that the air passing through the radiator 121 can flow to the air outlet 22 under the guidance of the deflector 23 and finally be blown out by the fan 30. It should be noted that the deflector 23 can be connected to the air guide cover 20 as a whole.

[0050] As preferably, Figure 4 As shown, the deflector 23 includes return air deflectors 231 located on both sides of the radiator 121 and inlet air deflectors 232 located on both sides of the fan 30. Both the return air deflectors 231 and the inlet air deflectors 232 have a certain curvature, and the inlet air deflectors 232 can prevent the generation of step vortices when air is drawn out of the air duct 201 to the environment. It should be noted that the return air deflectors 231 and inlet air deflectors 232 are devices for changing the direction or speed of fluid flow. They can be flat or angled arc plates and are installed in locations where gas flow needs to be affected. Their surfaces can be polished or textured to reduce flow resistance and optimize flow characteristics.

[0051] like Figure 4 As shown, the fan 30 is electrically connected to the main control board 13, so that when the tracking device 100 is in operation, the main control board 13 can be used to control the operation of the fan 30, thereby achieving automated control of the operation of the fan 30. It should be noted that the fan 30 and the main control board 13 can be connected using a quick-release connector to achieve electrical connection between the fan 30 and the main control board 13.

[0052] like Figure 3 、 Figure 4 As shown, the main control board 13 is connected to a heat sink 131 in a heat exchange manner, and the heat sink 131 partially extends into the air duct 201. The air flowing through the air duct 201 of the air guide cover 20 can dissipate heat from the heat sink 131 on the main control board 13, thereby achieving efficient heat dissipation of the main control board 13, thereby meeting the heat dissipation requirements of the tracking device 100 during operation.

[0053] In addition, the present application also provides a tracking scanner, including the tracking device 100 described above.

[0054] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
