Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0027] Example 1
[0028] This embodiment proposes a precise depth detection device; please refer to [link / reference]. Figures 1-4 This precise depth detection device includes a first moving component and a second moving component driven by the first moving component. For example... Figure 1 and Figure 3 As shown, the first moving component includes a first linear guide 2 that is coupled to the fixed part 1. The first linear guide 2 has a first extension 3, which faces downward. The first slider 6 slides in cooperation with the first extension 3. The first extension 3 is located beside the side of the first extension 3. Figure 1 (From the left side of the shown viewpoint) are two first wheels 5 with a gap between them. The first wheels 5 are rotatable, and the first wheels 5 have a consistent gap with the first extension 3. Figure 1 and Figure 3 As shown, the two first wheels 5 jointly support the first synchronous belt 4, allowing the first synchronous belt 4 to rotate around the two first wheels 5. It should be noted that the first synchronous belt 4 is connected to the first slider 6, and the first motor 7 is connected to one of the first wheels 5. Thus, the first slider 6 can slide relative to the first extension 3. Please continue reading. Figure 1 and Figure 3 The second moving component includes a second linear guide 8 fixedly coupled to the first slider 6. The second linear guide 8 has a second extension 9, which faces downward. The second slider 13 slides in cooperation with the second extension 9. The second extension 9 is located beside the second extension 9. Figure 1 (From the rear view shown) are two spaced second wheels 11, which are rotatable. The two second wheels 11 support a second synchronous belt 10, which is connected to a second slider 13. A second motor 12 is connected to one of the second wheels 11, allowing the second slider 13 to slide relative to the second extension 9.Figure 1 and Figure 3 For reference, in the embodiment, the first moving assembly can drive the second moving assembly to move forward and backward, and the second moving assembly can drive the second sliding block 13 to move left and right. Further, the second sliding block 13 is provided with a depth gauge 15, which is preferably a laser range finder. Further, the second sliding block 13 has a cavity 14, and two openings 16 for exposing the cavity 14, and the cavity 14 has a metal contact opposite to the opening 16, which is connected to the power supply of the depth gauge 15. The second sliding block 13 is inserted into the cavity 14 through the opening 16 and contacts the metal contact. Thus, when the first moving assembly and the second moving assembly are driven, the depth gauge 15 scans the workpiece.
[0029] In the embodiment, it is necessary to point out that the depth gauge 15 can not only scan downward, but also scan laterally. The downward scanning is mainly used to measure the depth of the internal cavity of the workpiece. If the workpiece has no cavity, the top surface of the workpiece can be scanned to determine whether there is a pit or a protrusion on the top of the workpiece. The lateral scanning is used to detect whether there is a pit or a protrusion on the side surface of the workpiece similar to the top end surface, and further to detect the quality of the workpiece. However, it should be noted that the downward scanning and the lateral scanning of the depth gauge 15 need to be adjusted. Specifically, one of the two openings 16 is downward, and the other opening 16 is forward. When the depth gauge 15 is inserted into the downward opening 16 and contacts the corresponding metal contact, the depth of the workpiece is detected. When the depth gauge 15 is inserted into the forward opening 16 and contacts the corresponding metal contact, the side surface of the workpiece is scanned. It should be further pointed out that when the depth gauge 15 scans downward, the workpiece needs to be located below the depth gauge 15, and when the depth gauge 15 scans laterally, the workpiece needs to be located in front of the depth gauge 15. It should be particularly pointed out in the embodiment that because the depth gauge 15 is an electronic device, heat will be generated during long-term use. Therefore, when the depth gauge 15 is arranged in one of the openings 16, the other opening 16 exposes the cavity 14, so that the heat in the cavity 14 can be dissipated in time.
[0030] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present disclosure.
[0031] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
