A calibration point sticker application device

Abstract

This utility model relates to a calibration point sticker pasting device, including a sleeve, a first rod, and a suction cup. The suction cup is fixedly installed on the bottom surface of the sleeve. The sleeve and suction cup have grooves for the first rod to slide back and forth within these grooves. The first rod is slidably positioned within these grooves. This utility model uses the suction cup to pick up the calibration point sticker. After aligning the sticker with the desired location on the scanned object, the sleeve is held to adhere the sticker to the object. The first rod is then pressed down to hold the sticker in place, while the suction cup is lifted, separating the sticker from the suction cup, thus completing the sticker pasting process. The entire process does not require touching the scanned object or the calibration point sticker and ensures accurate placement. It is particularly effective for small objects with complex geometric features that require pasting calibration point stickers in confined spaces.

Description

Technical Field

[0001] This utility model relates to the technical field of reverse scanning equipment in reverse engineering technology, specifically to an adhesive device for pasting calibration point stickers on the surface of the object to be scanned before scanning. Background Technology

[0002] In reverse engineering, obtaining a 3D model of an object through reverse scanning is crucial. Before scanning begins, the surface of the object often needs to be treated, typically by spraying on a layer of developer before attaching calibration point stickers. These calibration point stickers are usually quite small, making them difficult to apply to small objects or objects with small feature surfaces, especially on objects that have already been sprayed with developer; direct application can even cause the developer to rub against the surface.

[0003] Traditional manual pasting is difficult to operate precisely with human fingers, especially for small objects or objects with small features. This often results in problems such as smudging the surface after the developer has been sprayed or poor adhesion, leading to low efficiency and accuracy. To solve these problems, a new pasting device needs to be designed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a device for pasting calibration point stickers to overcome the shortcomings of the existing ones.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a calibration point sticker pasting device, comprising a sleeve, a first rod, and a suction cup, wherein the suction cup is fixedly installed on the bottom surface of the sleeve, and the sleeve and the suction cup are provided with a sliding groove for the first rod to slide back and forth, wherein the first rod is slidably placed in the sliding groove of the sleeve and the suction cup.

[0006] Preferably, the bottom end of the first rod is a disc-shaped pressing part.

[0007] Preferably, the inner surface of the suction cup extends into a receiving guide chamber that communicates with the slide groove, and the pressing part is placed in the receiving guide chamber and can reciprocate in and out of the receiving guide chamber.

[0008] Preferably, it also includes a second rod, which is reciprocally slidably mounted on the upper part of the sleeve, with the bottom end of the second rod connected to the top end of the first rod and the top end of the second rod positioned outside the top of the sleeve.

[0009] Preferably, a return spring is installed inside the sleeve, which is located below the second rod and sleeved on the outside of the first rod.

[0010] Preferably, a pressing cap is fixed to the top of the second rod.

[0011] Preferably, a guide groove is formed on the upper side wall of the second rod, and a guide bar is formed on the upper inner wall of the sleeve, with the guide bar slidingly engaging with the corresponding guide groove.

[0012] The advantages of this invention compared to existing technologies are as follows: This invention uses a suction cup to pick up the calibration sticker, aligns it with the desired location on the scanned object, and then, by holding the sleeve, adheres the calibration sticker from the suction cup to the object. The first rod is then pressed down to hold the calibration sticker in place, while the suction cup is lifted, separating the sticker from the suction cup, thus completing the application of the calibration sticker. The entire process requires no contact with the scanned object or the calibration sticker, and it ensures accurate placement. This is particularly effective for applications involving small objects with complex geometric features, where calibration stickers need to be applied in confined spaces. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Reference Figure 1 and Figure 2 It is known that a calibration point sticker pasting device is pen-shaped and includes a sleeve 1, a second rod 4, a first rod 2, and a suction cup 3.

[0019] The second rod 4 is reciprocally slidably mounted on the upper part of the sleeve 1. The bottom end of the second rod 4 is connected to the top end of the first rod 2. The top end of the second rod 4 is placed on the outside of the top of the sleeve 1 and a pressing cap 6 is fixed to the top end of the second rod 4.

[0020] A return spring 5 is installed inside the sleeve 2. The return spring 5 is located below the second rod 4 and sleeved on the outside of the first rod 2. This design allows the first rod 2 to automatically return to its original position after the pressing cap 6 drives the second rod 4 to move down, thereby causing the first rod 2 to move down.

[0021] The suction cup 3 is fixedly installed on the bottom surface of the sleeve 1. The sleeve 1 and the suction cup 3 have grooves 7 inside for the first rod 2 to slide back and forth. The first rod 2 is slidably placed within the grooves 7 of the sleeve 1 and the suction cup 3. (Refer to...) Figure 3 The bottom end of the first rod 2 is a disc-shaped pressing part 21; the inner surface of the suction cup 3 extends into a receiving guide chamber 31 that communicates with the slide groove 7, and the pressing part 21 is placed in the receiving guide chamber 31 and can move back and forth in and out of the receiving guide chamber 31.

[0022] Even better, a guide groove 41 is formed on the upper side wall of the second rod 4, and a guide bar 11 is formed on the upper inner wall of the sleeve 1, with the guide bar 11 slidingly engaging with the corresponding guide groove 41. Of course, in other embodiments, forming a guide bar on the second rod and a guide groove on the sleeve can also achieve the same sliding assembly effect.

[0023] This adhesive device, after the suction cup 3 picks up the calibration sticker, aligns it with the desired location on the scanned object, holds the sleeve 1, and adheres the calibration sticker from the suction cup 3 to the object. The second rod 4 is then pressed down, causing the pressing part 21 of the first rod 2 to move downwards, exiting the receiving guide chamber 31. The pressing part 21 presses down on the calibration sticker, while the suction cup 3 is lifted, separating the calibration sticker from the suction cup 3, thus completing the application of the calibration sticker. The entire process does not require touching the scanned object or the calibration sticker, and it can adhere to the accurate position. It is particularly effective for small objects with complex geometric features, where calibration stickers need to be applied in confined spaces.
