[0002] A full-automatic image measuring instrument is a high-precision and high-efficiency measuring device, mainly used for the measurement and analysis of two-dimensional or three-dimensional images. This kind of instrument has been widely used in many fields such as modern manufacturing, electronics industry, automotive engineering, aerospace and medical industry. The full-automatic image measuring instrument is developed on the basis of the digital image measuring instrument, integrating machine vision technology, and belongs to an advanced optical non-contact measuring device. It consists of a high-resolution camera, a precision moving stage and special measuring software, and realizes precise measurement through the combination of CCD digital image and computer screen measuring technology with spatial geometric operations. However, the parallel light illumination structure of the existing full-automatic image measuring instrument is not convenient for adjusting the height of the parallel light, so it is difficult to be applicable to the measurement of objects of different sizes, thus reducing the practicability.

After a large number of retrievals and inquiries, a parallel light illumination structure of a full-automatic image measuring instrument with the patent publication number of CN221301222U is found, which belongs to the field of image measuring instruments. This device drives the threaded shaft to rotate through a forward and reverse motor, and under the thread action of the threaded sleeve, the lamp body can be driven to lift and adjust by the threaded sleeve, so as to be applicable to the measurement of objects of different sizes.

[0004] However, there are still some problems in the above parallel light illumination structure of the full-automatic image measuring instrument. For example, since the position of the lamp body is fixed, only one side of the object can be measured. When it is necessary to measure other positions of the object, manual position adjustment is required, which makes it easy to have position errors during the adjustment process, thus affecting the overall detection result. In view of the above problems, the utility model proposes a parallel light illumination structure of a full-automatic image measuring instrument. Summary of the Utility Model

SPECIFIC EMBODIMENTS

[0023] The following will combine the attached drawings in the embodiments of the present utility model Figures 1-5 to clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0024] Please refer to Figures 1-5, in the embodiment of the present utility model, a parallel light illumination structure of a full-automatic image measuring instrument includes a base 1, on the top of which an installation table 2 is defined. A first external gear 3 is sleeved and rotatably connected on the installation table 2. An installation groove 16 for installing the first external gear 3 is provided on the base 1. A first gear 14 meshing with the first external gear 3 is rotatably connected inside the base 1. The first gear 14 is driven by a motor 6. A support frame 4 is fixed on the top of the first external gear 3. A measuring instrument mechanism 8 is slidably connected on the support frame 4. A slider 9 is fixedly connected to the measuring instrument mechanism 8. A sliding groove 12 for the slider 9 to slide and a driving mechanism 5 for driving the slider 9 to slide along the sliding groove 12 are provided on the support frame 4.

[0025] Specifically, first, the driving mechanism 5 drives the slider 9 to slide in the sliding groove 12 on the support frame 4. The slider 9 drives the measuring instrument mechanism 8 to move together. By precisely controlling the movement of the driving mechanism 5, precise position adjustment of the measuring instrument mechanism 8 on the support frame 4 can be achieved. In this way, according to different measurement requirements, the measuring instrument mechanism 8 can be adjusted to a suitable position to obtain the best measurement effect. Second, the motor 6 drives the first gear 14 to rotate. The first gear 14 meshes with the first external gear 3, thereby driving the first external gear 3 to rotate on the installation table 2. Since the support frame 4 is fixed on the top of the first external gear 3, the support frame 4 and the measuring instrument mechanism 8 thereon will also rotate together with the first external gear 3. In this way, rotational adjustment of the entire parallel light illumination structure in the horizontal direction can be realized to better align with the object to be measured, so as to facilitate the omnidirectional measurement of the object on the installation table 2, reduce the generation of errors, and improve the overall measurement accuracy.

[0026] It should be noted that the driving mechanism 5 is a structure that can drive the slider 9 to move along the support frame 4. The specific working mode and connection structure can refer to a parallel light illumination structure of a full-automatic image measuring instrument with a patent publication number of CN221301222U, or the driving mechanism 5 is an electric telescopic rod, etc. Second, the installation table 2 and the base 1 are integrally formed. The first external gear 3 can be rotatably connected to it through a bearing. At the same time, the connection mode of the overall equipment circuit is prior art. The motor 6 can adopt a positive generator 6 to realize the forward and reverse rotation of the first external gear 3 and avoid the winding of each equipment line. Further, the operation and installation of the measuring instrument mechanism are prior art and will not be described in detail here.

[0027] In the embodiment of the present utility model, such as Figure 1 、 Figure 4 and Figure 5As shown in the figure, a second external gear 15 is sleeved and fixedly connected to the installation table 2. A rotating rod 13 is rotatably connected inside the support frame 4. The first end of the rotating rod 13 extends into the base 1 and is sleeved with a second gear 17 that meshes with the second external gear 15. The rotating rod 13 is movably connected to the base 1. The second end of the rotating rod 13 penetrates and is movably arranged on the slider 9. A second bevel gear 11 is sleeved and movably arranged on the rotating rod 13. The second bevel gear 11 is rotatably arranged on the slider 9. A blower 10 with an air outlet facing the measuring instrument mechanism 8 is fixedly connected to the slider 9. A first bevel gear 18 that meshes with the second bevel gear 11 is sleeved on the drive shaft of the blower 10. The second external gear 15 is located in the installation groove 16 at the bottom of the first external gear 3, and the diameter of the second external gear 15 is smaller than the diameter of the first external gear 3. The rotating rod 13 has a square structure. A through hole 19 through which the rotating rod 13 can pass is provided through the first external gear 3. The diameter of the through hole 19 is larger than the maximum diameter of the cross-section at the bottom of the rotating rod 13. A through groove 7 through which the drive rod of the blower 10 can move is provided through the support frame 4. The through groove 7 and the sliding groove 12 are arranged in a staggered manner. The diameter of the second bevel gear 11 is larger than the diameter of the first bevel gear 18.

[0028] Specifically, when the first external gear 3 rotates, it will drive the second gear 17 on the rotating rod 13 to rotate along the second external gear 15, causing the rotating rod 13 to rotate. The second bevel gear 11 on the rotating rod 13 meshes with the first bevel gear 18 on the drive shaft of the blower 10, thereby driving the blower 10 to work and providing functions such as heat dissipation for the measuring instrument mechanism 8. The square structure of the rotating rod 13 and the design of the through hole 19 ensure the stability of the rotating rod 13 during rotation. At the same time, the second bevel gear 11 has an inner hole that fits the shape of the rotating rod 13, so as to ensure its lifting along the slider 9. It should be noted that the second bevel gear 11 can be rotatably connected to the slider 9 through a bearing, and the rotating rod 13 penetrates the second bevel gear 11 and the slider 9; further, the staggered arrangement of the through groove 7 and the sliding groove 12 ensures the independent movement of the blower 10 and the measuring instrument mechanism 8. The diameter relationship between the two bevel gears enables the blower 10 to operate at an appropriate speed, improving the heat dissipation effect and work efficiency.

[0029] Working principle: First, the driving mechanism 5 drives the slider 9 to slide within the chute 12 on the support frame 4. The slider 9 drives the measuring instrument mechanism 8 to move together. By precisely controlling the movement of the driving mechanism 5, precise position adjustment of the measuring instrument mechanism 8 on the support frame 4 can be achieved. In this way, according to different measurement requirements, the measuring instrument mechanism 8 can be adjusted to an appropriate position to obtain the best measurement effect. Secondly, the motor 6 drives the first gear 14 to rotate. The first gear 14 meshes with the first external gear 3, thereby driving the first external gear 3 to rotate on the mounting table 2. Since the support frame 4 is fixed on the top of the first external gear 3, the support frame 4 and the measuring instrument mechanism 8 thereon will also rotate together with the first external gear 3. Through this method, rotational adjustment of the entire parallel light structure in the horizontal direction can be achieved. At the same time, when the first external gear 3 rotates, it drives the second gear 17 on the rotating rod 13 to rotate along the second external gear 15, causing the rotating rod 13 to rotate. The second bevel gear 11 on the rotating rod 13 meshes with the first bevel gear 18 on the drive shaft of the fan 10, thereby driving the fan 10 to work and providing functions such as heat dissipation for the measuring instrument mechanism 8. The overall structure is simple to operate and has high linkage, enabling better alignment with the object to be measured, thus facilitating the all-round measurement of the object on the mounting table 2, reducing the generation of errors, and improving the accuracy of the overall measurement.
