[0038] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] like Figures 1 to 5 As shown, the laser installation structure of the utility model includes a frame 1, a shell 2, a mounting seat 3, a laser 4, a camera 5 and a fill light 6.

[0040] like Figures 1 to 4 As shown, the skeleton 1 is arranged in the shell 2; the mounting seat 3 is connected to the skeleton 1, and the mounting seat 3 is connected to the shell 2; the laser 4 is connected to the mounting seat 3, and the shell 2 is provided with an opening corresponding to the laser 4; the camera 5 is arranged on the end of the skeleton 1, and the camera 5 extends outside the shell 2;

[0041] As in the above structure, the frame 1 is used for installation, positioning and support of the laser 4 and the camera 5. During assembly, cameras 5 are provided at both ends of the frame 1, and the laser 4 is located between the two cameras 5. The laser 4 emits laser light to cooperate with the camera 5 to realize image acquisition.

[0042] In order to ensure structural stability and image acquisition accuracy, a mounting seat 3 is provided on the skeleton 1, and the laser 4, skeleton 1, shell 2 and mounting seat 3 are fixed as an integrated structure. In this way, the above components have good integrity and a relatively stable structure, which can ensure the image acquisition quality.

[0043] In some embodiments, the skeleton 1 is configured as a hollow structure, and the connecting harnesses of electrical components such as the laser 4 and the camera 5 are laid through the interior of the skeleton 1 .

[0044] Specifically, Figure 5 As shown, the inner wall of the housing 2 is provided with a receiving groove 201, and the mounting seat 3 is snap-fitted into the receiving groove 201;

[0045] As in the above structure, by setting a receiving groove 201 on the inner wall of the shell 2, the mounting seat 3 can be directly clamped and fixed, thereby positioning the skeleton 1 and the camera 5, and then the laser 4 can be fixed on the mounting seat 3, which can improve the convenience of positioning during assembly.

[0046] Specifically, the receiving groove 201 is formed by a portion of the housing 2 protruding inward.

[0047] Specifically, the mounting base 3, the laser 4 and the housing 2 are connected and fixed in series by bolts.

[0048] Specifically, the laser 4 is a line laser, and the laser 4 is rotatably connected to the mounting seat 3;

[0049] As in the above structure, the line laser has a high optical power and can scan the highly reflective surface, thereby obtaining more detailed point cloud data, thereby improving the imaging quality and solving the problem of poor imaging quality of conventional optical machine projection;

[0050] Specifically, when installing the line laser, a motor is provided, the motor is assembled on the mounting seat 3, and then the line laser is connected to the output shaft of the motor to realize the rotation of the line laser.

[0051] like Figure 5 As shown, the housing 2 includes a first side housing 21, a second side housing 22, a top housing 23 and a bottom housing 24, wherein the first side housing 21 and the second side housing 22 are arranged opposite to each other, and the mounting seat 3 is arranged on the first side housing 21 or the second side housing 22; the top housing 23 and the bottom housing 24 are arranged opposite to each other, and the top housing 23 and the bottom housing 24 are both connected to the first side housing 21 and the second side housing 22; the bracket frame 1, the mounting seat 3, the laser 4 and the camera 5 are all located in the space formed by the first side housing 21, the second side housing 22, the top housing 23 and the bottom housing 24;

[0052] As in the above structure, during assembly, after the skeleton 1 and the camera 5 are integrated, the skeleton 1, the mounting base 3 and the camera 5 are connected to the first side shell 21 or the second side shell 22, and then the assembly of other components is completed. Finally, the top shell 23 and the bottom shell 24 are connected and fixed to the first side shell 21 and the second side shell 22.

[0053] In some embodiments, during specific assembly, the first side shell 21 and the second side shell 22 are used to clamp the mounting seat 3 and the laser 4, and then bolts are set from the outside of the shell 2 to connect the mounting seat 3 and the laser 4 in series.

[0054] like Figure 1 As shown, the housing 2 further includes a clamping plate 25, the clamping plate 25 clamps the first side shell 21 and the second side shell 22, and the clamping plate 25 is provided with a through hole corresponding to the laser 4;

[0055] As in the above structure, by providing the clamping plate 25 to clamp the first side shell 21 and the second side shell 22, the structural stability of the housing 2 and its internal skeleton 1, the mounting seat 3, the laser 4 and the camera 5 can be ensured;

[0056] At the same time, the clamping plate 25 can also cover the bolt holes of the serial mounting seat 3 and the laser 4.

[0057] In some embodiments, the clamping plate 25 is configured as a U-shaped structure, and is clamped to the first side shell 21 and the second side shell 22; since the clamping plate 25 corresponds to the laser 4, the stability of the installation of the laser 4 can be further ensured;

[0058] In some embodiments, grooves are provided on both sides of the clamping plate 25 for installing nameplates to mark product model, parameters and other information.

[0059] like Figure 1 As shown, a plurality of fill lights 6 are arranged around the camera 5 to provide fill light and ensure imaging accuracy.

[0060] The three-dimensional laser scanner of the utility model comprises the laser installation structure as described above, and also comprises a control button 7 and a PCB board 8 .

[0061] The control button 7 is connected to the housing 2; the PCB board 8 is disposed in the housing 2, and the PCB board 8 is electrically connected to the control button 7, the laser 4 and the camera 5;

[0062] As shown in the above structure, the control button 7 and the PCB board 8 are used to control electrical components such as the laser 4 and the camera 5. In the specific layout, the control button 7 is integrated on the shell 2, and the PCB board 8 is set inside the shell 2.

[0063] like Figure 2 As shown, the control button 7 is arranged opposite to the laser 4, and a grip hole 202 is provided at a position of the housing 2 away from the laser 4;

[0064] As shown in the above structure, the control button 7 is arranged opposite to the laser 4, and a grip hole 202 is opened on the shell 2. Due to the opening of the grip hole 202, the shell 2 appears forked, which ensures the structural stability of the shell 2. The traditional scanner shell only has a gripping part without a fork and has relatively low strength.

[0065] In some embodiments, the skeleton 1 and the shell 2 are configured to have the same structure and are also composed of a detachable shell. The skeleton 1 can be configured to have two side shells, so that the camera 5 can be easily snapped in to complete the connection between the skeleton 1 and the camera 5, and it is also convenient to integrate the internal wiring harness of the scanner into the skeleton 1.

[0066] Specific implementation steps:

[0067] The camera 5 and the fill light 6 are integrated on the skeleton 1, and then connected with the first side shell 21 or the second side shell 22 of the shell 2, and then the laser 4, PCB board 8 and other components are assembled, and finally the other side shell, as well as the top shell 23, the bottom shell 24 and the clamping plate 25 are installed to form a complete shell 2. When assembling the shell 2, the control button 7 can be integrated synchronously.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
