Technical Field

[0001] The invention belongs to the technical field of 3D scanning, and in particular relates to a foldable 3D scanner. Background Art

[0002] 3D scanning technology, as an emerging technology field, plays an important role in many aspects. From clinical medicine, game entertainment, film technology, cultural relics research to industrial production, aerospace technology, and military technology, three-dimensional scanning imaging technology plays an important role. Among many applications, there are occasions where 3D scanners need to be frequently moved, so there is a requirement for the portability of 3D scanners.

[0003] Existing 3D scanners can be divided into desktop scanners and handheld scanners in terms of mechanical structure. Desktop 3D scanners are simple to operate and convenient to use, but since they require a platform to place the scanned object and the body is upright, they are large and difficult to carry. In other words, existing 3D scanner products cannot simultaneously meet the requirements of ease of operation and portability. Summary of the invention

[0004] In order to solve the problems in the prior art, the present invention provides a foldable 3D scanner.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a foldable 3D scanner, which includes a body component, a scanning platform and a connecting component, the body component includes a laser fixing arm and a body, the body includes a movable part and a fixed part, the number of the laser fixing arms is two, the two laser fixing arms are respectively hinged on the left and right sides of the movable part, the two laser fixing arms are both provided with a straight line laser, the lower part of the movable part is hinged to the fixed part, the connecting component includes a screw and a glass fiber board, the screw is fixedly connected to the glass fiber board, and the two ends of the screw are respectively connected to the fixed part and the scanning platform.

[0006] Furthermore, the lower side surfaces of the two laser fixing arms and the left and right side surfaces of the movable part are provided with a first magnetic part, which is in corresponding position and attracts each other, and the hinge surfaces of the two laser fixing arms and the movable part are provided with a second magnetic part, which is in corresponding position and attracts each other.

[0007] Furthermore, the first magnetic member and the second magnetic member are both neodymium magnets.

[0008] Furthermore, the laser fixing arm is connected to the movable part through a second hinge, and the movable part is connected to the fixing part through a first hinge.

[0009] Furthermore, the movable part and the fixed part are respectively provided with a first latch lock, the hole positions of the first latch lock correspond, a second latch lock is fixed on the fiberglass board, a protrusion is provided on the movable part, a through hole is opened at the protrusion, and the second latch lock corresponds to the through hole position opened at the protrusion.

[0010] Furthermore, the scanning platform includes a bottom plate, a base and a stepper motor, the base is connected to one end of the screw, the bottom plate is arranged on the base, the stepper motor is connected to the bottom plate to drive the bottom plate to rotate, and the bottom plate is made of acrylic material.

[0011] Furthermore, the number of the screws is two.

[0012] Furthermore, a camera is provided on the upper part of the movable part.

[0013] Furthermore, the fiberglass board is provided with a handle.

[0014] Furthermore, the laser fixing arm, the movable part and the fixed part are all 3D printed parts made of ABS material.

[0015] Compared with the prior art, the invention has the following beneficial effects: the invention solves the problem that the existing desktop 3D scanner is large in size and difficult to carry. It can simultaneously achieve ease of operation and structural portability, and the processing cost and difficulty are similar to those of the traditional desktop 3D scanner, thereby improving the portability of the 3D scanner while ensuring the scanning function.

[0016] The scanner is folded using a hinge. While realizing the basic scanning function, the laser fixed arm and the body can be folded. The size of the folded scanner is greatly reduced, making it easy to carry, and the cost and processing difficulty are similar to those of traditional scanners.

[0017] The folding state and working state stability of the scanner laser fixed arm are realized by rubidium magnets, and the sides and hinges of the machine body and laser fixed arm realize the restriction of the position of the laser fixed arm. Therefore, when in use, the laser fixed arm can be changed and stabilized by simply unfolding or folding it to the desired position. The folding state and working state stability of the machine body are realized by a latch lock. A latch lock is provided on the back of the machine body and on the fiberglass board fixedly connected to the connecting screw. When switching between the folding state and the working state, only the opening and closing of the lock needs to be adjusted. That is, the operation of folding and unfolding the scanner is convenient and fast.

[0018] The scanner body and laser fixed arm are made of ABS material, which not only meets the structural strength but also reduces the weight of the scanner, making the product lighter when carrying. BRIEF DESCRIPTION OF THE DRAWINGS
