It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] See also Figure 1-7 The utility model provides a technical solution: a sample scanning device, including a bed 1, a workbench 13 is provided on the top of the bed 1, the bed 1 is an X-axis from front to back, and the bed 1 is a Y-axis from left to right, and first sliding seats 2 are provided at both ends of the top of the bed 1 so as to be slidable along the X-axis, a first crossbeam 10 is provided between the two first sliding seats 2, a second sliding seat 5 is slidably provided on the front side of the first crossbeam 10, a laser rangefinder 6 is provided at the bottom of the second sliding seat 5, and the laser rangefinder 6 can move along the X and Y axes.

[0024] In this embodiment, the laser rangefinder 6 can move in a large range in the X-axis direction by sliding the first sliding seat 2 in the X-axis direction, and the laser rangefinder 6 can move in the Y-axis direction by sliding the second sliding seat 5 on the first beam 10. In this way, the laser rangefinder 6 can move freely on the two-dimensional plane and perform a comprehensive scan of the sample.

[0025] The sample to be scanned is placed on the workbench 13, the equipment is started, and the laser rangefinder 6 starts to move and scan the sample. The laser rangefinder 6 emits laser and receives reflected signals. By processing these signals, a digital image or three-dimensional model of the sample can be generated.

[0026] The front and rear sides of the bed 1 are fixedly connected to brackets 9, a second crossbeam 24 is provided between the two brackets 9, a third sliding seat 14 is slidably provided on the surface of the second crossbeam 24, and a camera 18 for capturing the template is provided at the bottom of the third sliding seat 14, and the camera 18 slides along its X-axis.

[0027] In this embodiment, the field of view of the camera 18 in a single shot can completely cover the X direction of the working platform and partially cover the Y direction of the working platform.

[0028] Use camera 18 to take a picture of the sample. If a single picture cannot completely cover the entire sample, multiple pictures can be taken by moving the camera 18. The data processing software can stitch the multiple pictures into one picture containing the complete sample, and obtain the approximate shape of the sample outline and its placement on the workbench 13 through the pictures.

[0029] By sliding the third sliding seat 14 on the second crossbeam 24 , the camera 18 can move in the Y-axis direction. This design allows the sample to be photographed at different angles and positions to meet diverse capture requirements.

[0030] Place the sample to be captured on the workbench 13 and ensure that it is within the shooting range of the camera 18. Start the device, and the camera 18 begins to slide along the Y-axis and adjust the shooting position and angle. When the camera 18 reaches the predetermined shooting position, it automatically captures the image of the sample. The captured image can be stored in the internal memory of the device or transmitted to the operating table 3 through the data transmission interface for further processing and analysis.

[0031] Furthermore, both ends of the top of the bed 1 are fixedly connected to a first rack 11, a first motor 19 is fixedly connected inside one of the first sliding seats 2, the output shaft of the first motor 19 is fixedly connected to a first gear 12 meshing with the first rack 11, and a second gear 15 meshing with the first rack 11 is rotatably provided in the other first sliding seat 2.

[0032] In this embodiment, when the first sliding seat 2 needs to be moved, the first motor 19 is started. Since the output shaft of the first motor 19 drives the first gear 12 to rotate, the first gear 12 and the first rack 11 are engaged, thereby driving one first sliding seat 2 to move along the X-axis. At the same time, since the two first sliding seats 2 are connected by the first crossbeam 10, and the second gear 15 in the other first sliding seat 2 is also engaged with the first rack 11, the other first sliding seat 2 will also move synchronously, thereby driving the laser rangefinder 6 and the camera 18 to scan and shoot in the X-axis direction.

[0033] Furthermore, a second rack 22 is provided on the top of the first crossbeam 10 , a second motor 20 is fixedly connected to the second sliding seat 5 , and an output shaft of the second motor 20 is fixedly connected to a third gear 16 meshing with the second rack 22 .

[0034] In this embodiment, when the second sliding seat 5 needs to be moved, the second motor 20 is started, and the output shaft of the second motor 20 drives the third gear 16 to rotate, and the third gear 16 engages with the second rack 22, thereby driving the second sliding seat 5 to move along the Y-axis. Since a laser rangefinder 6 is installed at the bottom of the second sliding seat 5, as the second sliding seat 5 moves, the laser rangefinder 6 will also be adjusted in the Y-axis direction to achieve scanning of different positions of the sample.

[0035] Furthermore, a third rack 23 is provided on the front side of the second crossbeam 24 , a third motor 21 is fixedly connected to the third sliding seat 14 , and an output shaft of the third motor 21 is fixedly connected to a fourth gear 17 meshing with the third rack 23 .

[0036] In this embodiment, when the third sliding seat 14 needs to be moved, the third motor 21 is started, and the output shaft of the third motor 21 drives the fourth gear 17 to rotate, and the fourth gear 17 engages with the third rack 23, thereby driving the third sliding seat 14 to move along the Y-axis. Therefore, as the third sliding seat 14 moves, the camera 18 will also be adjusted in the Y-axis direction to achieve shooting of different positions of the sample.

[0037] Furthermore, an L-shaped placement board 25 is detachably provided on the outer side of one of the brackets 9 , a display 4 is provided on the front side of the L-shaped placement board 25 , and an operating table 3 is provided on the top of the L-shaped placement board 25 .

[0038] In this embodiment, the L-shaped placement plate 25 and the bracket 9 are connected by bolts, snap connections, etc., and the L-shaped placement plate 25 can be easily installed and disassembled, which is convenient for maintenance and upgrading of the equipment.

[0039] The display 4 and the operating console 3 are connected to the control system of the scanning device via cables to achieve data transmission and reception of control instructions.

[0040] Furthermore, an inspection door 8 is rotatably provided on the front side of the bed 1 , and the inspection door 8 is rotatably connected to the front side of the bed 1 through a hinge 7 .

The door will smoothly rotate open under the action of the hinge 7, exposing the equipment inside or on the rear side of the bed 1. After completing the maintenance or inspection work, the operator can close the inspection door 8 and fix it in the closed position with the hinge 7.

[0042] The working principle and usage process of the present invention: After the present invention is installed, the template is first placed on the workbench 13, and the camera 18 is used to take a photo of the template. The approximate shape of the template outline and its placement on the workbench 13 are obtained through the photo. After that, the data processing software will find dozens to hundreds of important feature points on the template outline. At this time, the laser rangefinder 6 is started to accurately measure and locate the above-mentioned feature points one by one to obtain their precise coordinate values. Finally, the data processing software draws the accurate shape of the template according to the coordinate values ​​of the feature points and outputs it as a DXF drawing.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
