Description

Technical Field

[0001] This utility model relates to the field of printing equipment, and in particular to a three-dimensional scanning auxiliary device for printing equipment. Background Technology

[0002] 3D scanning for printing equipment typically refers to the 3D scanning technology used in the 3D printing (additive manufacturing) process to capture the geometry of real-world objects and convert it into digital models. These digital models can then be used for 3D printing, modification, analysis, or other manufacturing applications.

[0003] This technology has broad application prospects in multiple fields such as reverse engineering, rapid prototyping, and quality control. As the technology continues to advance, its importance in manufacturing and other industries will continue to grow.

[0004] Currently, most 3D scanning equipment uses specially designed fixed molds to fix the object to be scanned. When the size of the object to be scanned changes, the fixed mold must be replaced to fix the object. This method not only requires the prefabrication of a large number of fixed molds, which increases the cost of use, but also requires custom-made molds when the size of the object does not match the size of the prefabricated molds, which further increases the cost of use and takes a long time. In addition, existing 3D scanning equipment can only scan one object at a time, resulting in low scanning efficiency.

[0005] Therefore, a printing device using a 3D scanning auxiliary device is proposed to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a three-dimensional scanning auxiliary device for printing equipment. By setting a three-dimensional scanning object positioning fixture, the device can quickly position the object to be scanned. At the same time, it can cooperate with a turntable to achieve clamping and scanning of multiple objects at a time, thereby improving scanning efficiency.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A 3D scanning auxiliary device for a printing device includes a mounting base;

[0009] A bracket is mounted on the upper end face of the mounting base, and a linear screw module is vertically mounted on the side of the bracket.

[0010] The linear lead screw module is equipped with a slider, and a three-dimensional scanning camera body is mounted on the side of the slider; the three-dimensional scanning camera body moves linearly along the vertical stroke of the linear lead screw module via the slider;

[0011] An electric turntable is mounted on the side of the linear screw module. A drive shaft is assembled at the output end of the electric turntable. A rotating platform is mounted on the upper surface of the drive shaft. Several sets of three-dimensional scanning object positioning fixtures are distributed on the upper surface of the rotating platform.

[0012] Furthermore, the three-dimensional scanning object positioning fixture includes a push seat that is slidably disposed on a rotating table. A limit shaft is vertically disposed on the upper end face of the push seat. Two adjusting arms are rotatably disposed on the outside of the push seat, and clamping arms are integrally connected to the ends of the two adjusting arms.

[0013] Furthermore, both of the adjusting arms are provided with sliding grooves, which are arranged in an X-shape and intersecting each other. The limiting shaft rotates at the intersection of the two sliding grooves.

[0014] Furthermore, the clamping arm and the adjusting arm are arranged in an L-shape; the two clamping arms extend in parallel and are provided with clamping grooves on their opposite sides, and anti-slip textures are provided in the clamping grooves.

[0015] Furthermore, the three-dimensional scanning object positioning fixture also includes two positioning seats disposed on the upper surface of the rotating platform. A small lead screw is rotatably disposed between the two positioning seats. The small lead screw passes through and meshes with the push seat. One end of the small lead screw passes through one of the positioning seats and extends to be connected to a rotating handle.

[0016] Furthermore, the three-dimensional scanning object positioning fixture also includes a limiting seat disposed on the rotating table, and the limiting seat has an inner groove arranged in a U-shape.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. By cooperating with multiple structures within the 3D scanning object positioning fixture, it can position 3D objects of different sizes for scanning, ensuring the object remains stable throughout the inspection process. Furthermore, through the rotational engagement between the drive shaft and the rotating stage, and the arrangement of multiple sets of 3D scanning object positioning fixtures, this invention enables parallel processing of multiple objects, significantly reducing the time required to scan a single object. This allows for the simultaneous preparation and clamping of multiple objects, reducing preparation time before each scan and thus substantially improving overall production efficiency.

[0025] First embodiment;

[0026] Reference Figure 1-3 As shown, a 3D scanning auxiliary device for printing equipment is provided in a preferred embodiment of the present invention, including a mounting base 1;

[0027] Mounting base 1 is equipped with a bracket 2 on its upper end face, and a linear lead screw module 3 is vertically mounted on the side of the bracket 2.

[0028] The linear lead screw module 3 is equipped with a slider and a 3D scanning camera body 4 is mounted on the side of the slider; the 3D scanning camera body 4 moves linearly along the vertical stroke of the linear lead screw module 3 via the slider.

[0029] An electric turntable 5 is mounted on the side of the linear screw module 3. A drive shaft 6 is assembled at the output end of the electric turntable 5. A rotating table 7 is mounted on the upper surface of the drive shaft 6. Several sets of three-dimensional scanning object positioning fixtures 8 are distributed on the upper surface of the rotating table 7.

[0030] In this embodiment, the cooperation of multiple structures within the 3D scanning object positioning fixture 8 enables the positioning of 3D objects of different sizes, ensuring the object remains stable throughout the scanning process. Furthermore, the rotational cooperation between the drive shaft 6 and the rotating stage 7, along with the multiple sets of 3D scanning object positioning fixtures 8, allows for the parallel processing of multiple objects, significantly reducing the time required to scan a single object. This allows for the simultaneous preparation and clamping of multiple objects, reducing preparation time before each scan and thus greatly improving overall production efficiency.

[0031] Second embodiment;

[0032] Reference Figure 2-3 As shown, the 3D scanning object positioning fixture 8 includes a push seat 85 that is slidably disposed on a rotating table 7. A limit shaft 86 is vertically disposed on the upper end surface of the push seat 85. Two adjusting arms 87 are rotatably disposed outside the push seat 85, and clamping arms 89 are integrally connected to the ends of the two adjusting arms 87.

[0033] In this embodiment, when the push seat 85 moves toward the center of the rotating table 7, the two clamping arms 89 will move in opposite directions until the two clamping arms 89 clamp and position the three-dimensional scanned object located in the limiting seat 81.

[0034] Third embodiment;

[0035] Reference Figure 2-3 As shown, both adjusting arms 87 are provided with sliding grooves 88, which are arranged in an X-shape. The limiting shaft 86 rotates at the intersection of the two sliding grooves 88.

[0036] In this embodiment, when the push seat 85 is pushed forward, it is limited by the sliding groove 88 and the limiting shaft 86, at which time the two clamping arms 89, which are X-shaped and intersecting, will separate in a Y-shape.

[0037] Fourth embodiment;

[0038] Reference Figure 2-3 As shown, the clamping arm 89 and the adjusting arm 87 are arranged in an L-shape; the two clamping arms 89 extend in parallel and are provided with clamping grooves 810 on their opposite sides, and anti-slip textures 811 are provided in the clamping grooves 810.

[0039] In this embodiment, the clamping arm 89 and the adjusting arm 87 are arranged in an L-shape. In preferred use, the two clamping arms 89 can stably clamp the 3D scanned object. At the same time, the clamping groove 810 and anti-slip texture 811 on the clamping arm 89 can further stabilize the 3D scanned object and prevent it from loosening during clamping.

[0040] Fifth embodiment;

[0041] Reference Figure 2-3 As shown, the 3D scanning object positioning fixture 8 also includes two positioning seats 82 disposed on the upper surface of the rotating table 7. A small lead screw 83 is rotatably disposed between the two positioning seats 82. The small lead screw 83 passes through the push seat 85 and is engaged with the push seat 85. One end of the small lead screw 83 passes through one of the positioning seats 82 and extends to be connected to a rotating handle 84.

[0042] In this embodiment, the two positioning seats 82 can be used for assembling the small lead screw 83. In a preferred embodiment, bearing components can also be assembled on the positioning seats 82 to improve the smoothness of the rotation of the small lead screw 83. When the small lead screw 83 rotates, it is limited by the rotating table 7. At this time, the push seat 85 set on the rotating table 7 can make linear movements on the rotating table 7. The rotating handle 84 can be used to drive the rotation of the small lead screw 83.

[0043] Sixth embodiment;

[0044] Reference Figure 3 As shown, the 3D scanning object positioning fixture 8 also includes a limiting seat 81 disposed on the rotating table 7, and the limiting seat 81 has a U-shaped inner groove 801.

[0045] In this embodiment, the recessed groove 801 can be used by the user to place the three-dimensional object to be measured into the three-dimensional scanning object positioning fixture 8.

[0046] Specific implementation process:

[0047] Step 1: The user places the 3D object to be measured into the 3D scanning object positioning fixture 8. Then, the user uses the cooperation of multiple components in the 3D scanning object positioning fixture 8 to clamp and position the 3D object. After the 3D object is positioned, the user can drive the linear screw module 3 to move, so that the linear screw module 3 drives its slider and the 3D scanning camera body 4 mounted on the slider to move vertically up and down.

[0048] Step 2: When the 3D scanning camera body 4 moves to the side of the 3D scanning object positioning fixture 8, the 3D scanning camera body 4 can scan the 3D scanning object. After the 3D scanning camera body 4 transmits the scanned data to the printing device, the printing device can then perform 3D printing on the 3D object.

[0049] Step 3: During the scanning of a 3D object, the user can also connect the electric turntable 5 to a power source. At this time, the electric turntable 5 will drive the transmission shaft 6 and the rotating table 7 to rotate, thereby causing several sets of 3D scanning object positioning fixtures 8 on the rotating table 7 to move sequentially to one side of the 3D scanning camera body 4 for scanning. At this time, the user can prepare multiple objects to be scanned, reducing the preparation time before each scan, and enabling parallel scanning of multiple objects.
