Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of 3D scanners, and in particular to a 3D scanner with automatic calibration. Background Technology
[0002] A cabinet-style 3D scanner is a special type of 3D scanning device. It has a cabinet-like structure that allows objects to be placed inside for omnidirectional scanning, quickly acquiring the object's three-dimensional data. It is widely used in fields such as industrial design and cultural relic preservation, providing strong support for accurate modeling.
[0003] Cabinet-style 3D scanners only have one rotatable door for placing items. When servicing the 3D scanner, the cabinet is restricted by its single opening method, allowing operation only from this one direction. This makes the space inside the cabinet relatively narrow and inconvenient for maintenance personnel to operate. Moreover, if some complex faults are encountered that require observation and handling from multiple angles, this door will become a major obstacle, affecting the efficiency and quality of maintenance.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Example 1
[0034] This utility model provides, for example Figure 1-4 The 3D scanner shown includes a frame 1, a scanner body 2, a mounting frame 3, a cabinet door 4, a mounting rod 5, and a locking mechanism 6. The scanner body 2 is located inside the frame 1. The mounting frame 3 is slidably inserted into the inner cavity of the frame 1. The cabinet door 4 is rotatably mounted inside the mounting frame 3 via a pivot. One end of the mounting rod 5 is fixedly connected to the mounting frame 3. Mounting holes are equidistantly provided on the inner wall of the frame 1. The other end of the mounting rod 5 is slidably inserted into the inner cavity of the mounting holes. The locking mechanism 6 is located inside the mounting frame 3 and is used for multi-point positioning of the mounting frame 3. When a comprehensive overhaul of the cabinet-type 3D scanner is required, the mounting frame 3 and the cabinet door 4 can be easily separated by operating the locking mechanism 6. After disassembly, maintenance personnel can enter the interior without hindrance to conduct detailed inspection and repair of each component, greatly improving the convenience and efficiency of maintenance and providing a strong guarantee for the stable operation of the equipment.
[0035] Specifically, the locking mechanism 6 includes a slide rod 61, a sliding plate 62, a positioning rod 63, and a compression spring 64. The mounting frame 3 has equidistant extrusion grooves inside. The end of the slide rod 61 is fixedly connected to the inner wall of the extrusion groove. The sliding plate 62 is slidably inserted into the slide rod 61. Positioning holes are provided at the top and bottom of the inner wall of the frame 1. One end of the positioning rod 63 is fixedly connected to the sliding plate 62, and the other end is slidably inserted into the inner cavity of the positioning hole. The compression spring 64 is sleeved on the outside of the slide rod 61. One end of the compression spring 64 is fixedly connected to the sliding plate 62, and the other end is fixedly connected to the inner wall of the extrusion groove. The compression spring 64 is always in a compressed state, thus providing a stable elastic force to the positioning rod 63 through the sliding plate 62, allowing for stable locking with the positioning hole. When locking with the hole, the mounting frame 3 can be fixed inside the frame 1 for convenient normal use.
[0036] Example 2
[0037] Based on Example 1, such as Figure 5 As shown, the snap-fit mechanism 6 also includes a pull rod 65, a pull ring 66, and a limiting rod 67. Both sides of the mounting frame 3 have pull grooves communicating with the extrusion groove. The pull rod 65 passes through the pull groove and is fixedly connected to the slide plate 62. When the scanner body 2 needs to be inspected, the slide plate 62 can be pulled by the pull rod 65, thereby driving the positioning rod 63 to disengage from the positioning hole, so that the mounting frame 3 and the cabinet door 4 can be disassembled. After disassembly, the inspection space for maintenance personnel is expanded, which facilitates detailed inspection and maintenance of various components. The outer wall of the pull rod 65 has a through groove, and the pull ring 66 is rotatably set inside the through groove. The limiting rod 67 is fixedly connected to both sides of the mounting frame 3 at equal intervals. The outer wall of the limiting rod 67 has a groove that cooperates with the pull ring 66. After pulling the pull rod 65 to release the positioning of the positioning rod 63, the positioning rod 63 can be kept inside the mounting frame 3 by snapping the pull ring 66 into the groove of the limiting rod 67, which facilitates subsequent reinstallation.
[0038] Furthermore, a laser rangefinder 7 is fixedly mounted at equal intervals on the top of the scanner body 2 for automatically calibrating the position of the scanner body 2. The laser rangefinder 7 typically achieves automatic calibration through internal sensors and a control system. It emits a laser beam and receives the reflected light signal, calculates the distance to the target object based on the propagation time of the light signal. During the operation of the scanner, it continuously performs distance measurement operations and compares the measurement results with a preset standard position or reference point. If a distance deviation is detected, the control system will adjust according to the deviation value, fine-tuning the position of the scanner body 2 through a drive mechanism or other means, thereby achieving automatic calibration and ensuring the accuracy and precision of the scan.
[0039] Furthermore, an observation window 8 is embedded in the outer wall of the cabinet door 4. The observation window 8 is made of transparent material. A ventilation window 9 is fixedly connected to the outer wall of the cabinet door 4. The observation window 8 allows the operator to observe the inside of the scanner without opening the cabinet door 4, making it easier to detect problems in time. The fixed ventilation window 9 ensures air circulation inside the cabinet, prevents the equipment from overheating, and plays a good role in ensuring the normal operation of the scanner.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
