Technical Field

[0001] The utility model relates to the technical field of three-dimensional modeling auxiliary scanning, in particular to a point sticking auxiliary tool for laser scanning of three-dimensional modeling. Background Art

[0002] In layman's terms, "3D modeling" is to use 3D production software to build a model with 3D data in a virtual 3D space. 3D modeling can be roughly divided into two categories: NURBS and polygonal mesh;

[0003] A 3D model is a polygonal representation of an object, usually displayed by a computer or other video device. The displayed object can be a real-world entity or a fictional object. Anything that exists in the physical world can be represented by a 3D model. The best and fastest way to build a 3D model of an existing object is through laser scanning. In order to improve the accuracy of laser scanning, points are often added to the surface of the object.

[0004] The existing method of pasting dots is mainly done manually by staff. Manual pasting requires pasting the dots one by one, which has the problem of low pasting efficiency. After the scanning is completed, the dots need to be removed one by one, which is cumbersome to operate and has poor practicality. For this reason, the utility model proposes a dot pasting auxiliary tool for laser scanning of three-dimensional modeling. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The three-dimensional modeling laser scanning point sticking auxiliary tool of the utility model directly integrates a plurality of magnetic sticking points on a point sticking auxiliary belt. Therefore, in actual use, it is only necessary to stick the entire point sticking auxiliary belt once, and there is no need to stick the magnetic sticking points one by one. The sticking efficiency is high, and when removing, it is only necessary to tear off the entire point sticking auxiliary belt, and there is no need to remove them one by one.

[0024] See also Figure 1-5 The utility model provides an embodiment: a point-attaching auxiliary tool for laser scanning of three-dimensional modeling, comprising a primary square side panel 1 and a secondary square side panel 2, wherein, in order to improve the structural adaptability and external structural aesthetics of the point-attaching auxiliary tool of the utility model, the primary square side panel 1 and the secondary square side panel 2 have the same surface area, and the four corners of the primary square side panel 1 and the secondary square side panel 2 are all designed with arc structures;

[0025] The primary square side panel 1 and the secondary square side panel 2 are arranged opposite to each other, and a point-sticking auxiliary cylinder 3 is fixedly installed between the primary square side panel 1 and the secondary square side panel 2. The inside of the point-sticking auxiliary cylinder 3 is designed as a hollow structure. An inner rotating shaft 6 is rotatably installed at the center position of the inner point-sticking auxiliary cylinder 3 through a bearing. The outer part of the inner rotating shaft 6 is sleeved with a point-sticking auxiliary belt 7. A soft magnetic layer 9 is arranged on the outer side of one side of the point-sticking auxiliary belt 7, and an adhesive layer 8 is arranged on the outer side of the other side of the point-sticking auxiliary belt 7. The adhesive layer 8 can be used to stick the point-sticking auxiliary belt 7 on the object to be laser scanned;

[0026] Among them, as an optimized technical solution of the utility model, in actual use, an adhesive protection strip similar to a double-sided tape can be attached to the outside of the adhesive layer 8, so as to effectively prevent the tape bodies from sticking to each other when winding up. When in use, the adhesive protection strip can be torn off to expose the adhesive layer 8, so as to carry out the pasting work, thereby improving the use quality of the adhesive layer 8 and preventing the tape bodies from sticking to each other;

[0027] The soft magnetic layer 9 is provided with a plurality of magnetic spots 10 which are linearly distributed at equal intervals.

[0028] Furthermore, in order to facilitate the adjustment of the spacing of the magnetic points 10 to suit different use requirements and use environments, a soft magnetic sheet 11 is provided on the bottom surface of the magnetic points 10, and the magnetic points 10 are magnetically connected to the soft magnetic layer 9 through the soft magnetic sheet 11;

[0029] By magnetically connecting the magnetic sticking point 10 with the sticking auxiliary belt 7, the position of the sticking point can be adjusted while having a certain fixing effect, so that the position of a single magnetic sticking point 10 can be conveniently adjusted to meet more usage scenarios and usage requirements. The sticking point has the adjustability of dynamic removable structure, high structural flexibility, and is easy to use.

[0030] In this embodiment, in order to facilitate the internal installation of the rolled-up auxiliary tape 7, a circular slot is provided at the center of the secondary square side plate 2, and a side circular plate 5 is fixedly installed on the outside of the circular slot by screws;

[0031] With this structural design, when it is necessary to place the auxiliary tape 7 inside the auxiliary tube 3, the screws on the side circular plate 5 can be removed, so that the side circular plate 5 can be removed, so that the auxiliary tube 3 can be exposed. Figure 2 As shown;

[0032] At this time, the rolled-up auxiliary tape 7 can be sleeved on the inner rotating shaft 6 of the auxiliary tube 3, so that the placement and installation of the auxiliary tape 7 can be completed;

[0033] Furthermore, in order to facilitate the stretching of the auxiliary tape 7, an outlet 4 is provided on the outer wall of one side of the bottom end of the auxiliary tube 3, and one end of the auxiliary tape 7 passes through the outlet 4;

[0034] Thus, by stretching the end of the auxiliary tape 7 in the tape opening 4, the auxiliary tape 7 can be stretched and pulled out from the auxiliary tube 3, so as to facilitate the subsequent tape body pasting work.

[0035] Working principle: Before using the point sticking auxiliary tool, roll up the belt assembly consisting of the point sticking auxiliary belt 7 and a plurality of magnetic sticking points 10;

[0036] The side circular plate 5 can be removed. After the side circular plate 5 is removed, the interior of the auxiliary tube 3 is in an open state (see the attached manual for details). Figure 2 As shown), at this time, the rolled-up belt body assembly is sleeved on the outside of the inner rotating shaft 6, and the stretched end of the auxiliary tape 7 is passed through the tape outlet 4 of the auxiliary tube 3, so that the subsequent stretching and taping can be conveniently performed;

[0037] When in use, the auxiliary tape 7 in the tape outlet 4 can be manually pulled to pull the auxiliary tape 7 out of the auxiliary tube 3 so that the auxiliary tape 7 is in a straight line.

[0038] At this time, the pulled-out point-sticking auxiliary belt 7 can be stuck on the scanned object through the provided adhesive layer 8, and a plurality of magnetic points 10 are magnetically connected to the point-sticking auxiliary belt 7, so that the three-dimensional scanning of the object can be completed through the cooperation of the magnetic points 10;

[0039] After scanning is completed, the auxiliary tape 7 can be torn off as a whole, and the magnetic dots 10 thereon can be scraped off in sequence by a scraper, so that the auxiliary tape 7 and the magnetic dots 10 can be classified and recycled. The auxiliary tape 7 can be recycled as waste, and the magnetic dots 10 can be reused with a new auxiliary tape 7.

[0040] When the belt assembly inside the auxiliary tube 3 is used up, the auxiliary tube 3 can be opened again through the side circular plate 5, and a new belt assembly can be sleeved on the inner rotating shaft 6 of the auxiliary tube 3 for continuous use;

[0041] Furthermore, in actual use, the auxiliary tape 7 can be cut into sections according to actual use requirements to be suitable for three-dimensional scanning of objects of different sizes, thereby effectively increasing the scope of use;

[0042] The three-dimensional modeling laser scanning point sticking auxiliary tool of the utility model directly integrates a plurality of magnetic sticking points 10 on a point sticking auxiliary belt 7. Therefore, in actual use, it is only necessary to stick the entire point sticking auxiliary belt 7 once, and there is no need to stick the magnetic sticking points 10 one by one. The sticking efficiency is high, and when removing, it is only necessary to tear off the entire point sticking auxiliary belt 7, and there is no need to remove them one by one.

[0043] At the same time, the torn off auxiliary tape 7 is scraped off the magnetic dots 10 in sequence by the scraper, so that the auxiliary tape 7 and the magnetic dots 10 can be classified and recycled. The auxiliary tape 7 can be recycled as waste, and the magnetic dots 10 can be reused with the new auxiliary tape 7, which has the effect of recycling and reusing waste, greatly improving the overall utilization efficiency of the structure and effectively avoiding structural waste.

[0044] The magnetic sticker 10 is connected to the sticker auxiliary belt 7 by magnetic attraction, and the position of the sticker can be adjusted while having a certain fixing effect. This makes it convenient to remove and adjust the position of a single or multiple magnetic stickers 10, thereby meeting more usage scenarios and usage requirements, greatly improving the scope of application of the utility model, and having the adjustability of the sticker dynamically removable, the structure is highly flexible, and is easy to use, effectively improving the accuracy of scanning.
