Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary lighting for three-dimensional scanning equipment, and in particular to auxiliary lighting equipment for scanning equipment in a dark environment. Background Art

[0002] A 3D scanner is a scientific instrument used to detect and analyze the shape (geometry) and appearance data (such as color, surface albedo, etc.) of objects or environments in the real world. The collected data is often used for 3D reconstruction calculations to create digital models of actual objects in the virtual world. These models have a wide range of uses, including industrial design, defect detection, reverse engineering, robot guidance, topographic measurement, medical information, bioinformatics, criminal identification, digital cultural relics collection, film production, game creation materials, etc. Among them, photographic 3D scanners are often used to scan the appearance and structure of objects in a dark environment.

[0003] At present, when a photographic 3D scanner scans the shape of an object in a dark environment, it mainly relies on the built-in fill light on the scanner to fill in the light around the object to ensure that the 3D scanner can scan the shape of the object normally in a dark environment. However, since the installation position and irradiation angle of the fill light on the existing photographic 3D scanner are fixed, when the 3D scanner scans the object in a dark environment, it is easy to cause the fill light to be far away from the object to be measured and the fill light angle is unreasonable, resulting in low brightness around the object to be measured, making the brightness of the 3D scanner poor after taking the photo, which is not convenient for accurate photographing and scanning of the object to be measured in a dark environment. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is to provide a kind of auxiliary lighting device for scanning equipment in dark environment, which can realize the flexible adjustment of the height and lighting angle of the fill light board and ensure the accurate scanning of the object to be tested by the three-dimensional scanner in dark environment.

[0006] (II) Technical solution

[0007] The utility model is implemented through the following technical scheme: the utility model proposes an auxiliary lighting device for scanning equipment taking photos in a dark environment, including a vertical plate, a lifting mechanism installed on one side wall of the vertical plate, the lifting mechanism including a gear rod installed on the top inner side of the vertical plate, a driving motor installed on the outer side wall of the vertical plate facing the gear rod, two threaded rods symmetrically installed on the vertical plate at the lower side of the gear rod, a transmission gear installed at the connection position between each threaded rod and the gear rod, a slide groove opened on the vertical plate at the threaded rod, a slider installed on the threaded rod, a mounting rod welded on the side of the slider facing away from the slide groove, a fill light board is installed on one side of the upper bottom end of the mounting rod through a rotating mechanism, the rotating mechanism including a mounting groove opened on the mounting rod at the fill light board, a rotating shaft installed between the inner wall of the mounting groove and the fill light board, and a rotating motor installed on one side wall of the mounting rod facing the rotating shaft.

[0008] Furthermore, a U-shaped counterweight base is welded to the bottom end of the vertical plate, and a universal wheel is connected to each of the four corners of the bottom end of the counterweight base through bolts.

[0009] By adopting the above technical solution, the U-shaped counterweight base can store the chassis of the photographic 3D scanner when in use, ensuring that the fill light panel can be located on both sides of the photographic 3D scanning device when in use, so as to provide fill light for the objects to be scanned from both sides.

[0010] Furthermore, a U-shaped push handle is welded to the upper part of the side wall of the vertical plate facing away from the slide slot, an operation panel is installed on the push handle, and a battery is also installed on the vertical plate above the push handle.

[0011] By adopting the above technical solution, the device can be flexibly moved and used by holding the push handle, which is convenient for providing supplementary light to objects when scanning in a dark environment.

[0012] Furthermore, the operation panel is electrically connected to the driving motor and the rotating motor.

[0013] By adopting the above technical solution, the operation panel mainly realizes the orderly opening and closing of the driving motor and the rotating motor by controlling the on-off of the circuit, so as to conveniently fill in the light for the object to be tested.

[0014] Furthermore, the gear rod is rotatably connected to the vertical plate, and the vertical plate is hollow in the location of the gear rod.

[0015] By adopting the above technical solution, it can be ensured that the gear rod can rotate conveniently under the action of the driving motor.

[0016] Furthermore, the transmission gear is welded to the threaded rod, the transmission gear is meshed with the gear rod, and the threaded rod is rotationally connected to the slide groove.

[0017] By adopting the above technical solution, after the gear rod rotates, the transmission gear will transmit power to the threaded rod to realize the rotation of the threaded rod. After the threaded rod rotates, the slider will rise and fall along the slide groove under the action of the thread transmission, thereby realizing the adjustment of the lighting height of the lighting panel.

[0018] Furthermore, the threaded rod passes through the slider and is threadedly connected to the slider, and the slider is slidably connected to the slide groove.

[0019] By adopting the above technical solution, stable sliding of the sliding block relative to the sliding groove can be ensured.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] In order to solve the problem that the current photographic 3D scanner scans the shape of an object in a dark environment, the scanner mainly uses the built-in fill light on the scanner to fill light the environment around the object to ensure that the 3D scanner can scan the shape of the object normally in a dark environment. However, since the installation position and irradiation angle of the fill light on the existing photographic 3D scanner are fixed, when the 3D scanner scans the object in a dark environment, it is easy to cause the fill light to be far away from the object to be measured and the fill light angle is unreasonable, resulting in low brightness around the object to be measured, making the brightness of the 3D scanner poor after taking pictures, which is not convenient for scanning the object to be measured in a dark environment. In order to solve the problem of accurate photo scanning, the utility model adopts the coordinated design of the lifting mechanism and the rotating mechanism, so that when the fill light device is in use, it can not only use the driving motor in the lifting mechanism to drive the gear rod to rotate, so that the height of the fill light board can be conveniently adjusted through the transmission gear and the gear rod while the gear rod rotates, ensuring that the distance between the fill light board and the object to be measured is appropriate, but also cooperate with the rotating motor and the rotating shaft in the rotating mechanism to adjust the illumination angle of the fill light board, ensuring that there is no illumination blind spot on the surface of the object to be measured when scanning in a dark environment, so that the three-dimensional scanning device can perform accurate photo scanning on the object to be measured in a dark environment.
