[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 4As shown, a large-scale component three-dimensional size detection device includes a device body, which includes a first support frame 2, a second support frame 3, a mechanical arm 42 mechanism fixed between the first support frame 2 and the second support frame 3, and an AGV trolley 5 for transporting workpieces; the mechanical arm 42 mechanism includes a connecting beam 41 and a mechanical arm 42, one side of the connecting beam 41 is fixedly connected to the first support frame 2, and the other side of the connecting beam 41 is fixedly connected to the second support frame 3, and the bottom of the connecting beam 41 is hoisted and fixed with a mechanical arm 42, and the mechanical arm 42 has a 3D camera 43;

[0020] The AGV trolley 5 is located below the connecting beam 41. The AGV trolley 5 has a workpiece placement platform 51. The 3D camera 43 can always illuminate and detect the workpiece placement platform 51. The mechanical arm 42 is a six-axis articulated mechanical arm 42.

[0021] In the present invention, the robot arm 42 is a six-axis articulated robot arm 42 in the prior art, and the angle and position of the 3D camera 43 on the robot arm 42 can be flexibly adjusted from the first axis to the sixth axis, from the horizontal plane to the three-dimensional space. The AGV trolley 5 and the 3D camera are also prior art.

[0022] With the above structure, the operator places the large workpiece from the machine onto the AGV trolley 5, and then controls the AGV trolley 5 to carry the large workpiece to the bottom of the mechanical arm 42 of the connecting beam 41, and then controls the mechanical arm 42 that can move in any horizontal and vertical directions to adjust, and adjusts the 3D camera 43 installed on the mechanical arm 42 to a precise detection position. The 3D camera 43 shoots the surface of the object, reconstructs the three-dimensional information of the surface of the large workpiece, and then automatically measures the key dimensions of the large workpiece. Subsequently, the large workpiece is transported out of the equipment by the AGV trolley 5, which is conducive to avoiding detection errors and production safety accidents that may occur in traditional manual detection methods, and is safer during transportation. At the same time, during detection, the large workpiece is detected by combining the mechanical arm 42 and the 3D camera 43 in an installed manner, with high detection efficiency, precise detection, and higher detection accuracy. There is no need to manually flip the detection surface of the workpiece, which is more convenient for detection.

[0023] like Figures 1 to 4 As shown, the first support frame 2 has two first columns 21 and a first beam 22 fixed on the top of the two first columns 21 , one end of the first beam 22 is fixedly connected to one of the first columns 21 , and the other end of the first beam 22 is fixedly connected to the other first column 21 .

[0024] The second support frame 3 has two second columns 31 and a second beam 32 fixed on the top of the two second columns 31, one end of the second beam 32 is fixedly connected to one of the second columns 31, and the other end of the second beam 32 is fixedly connected to the other second column 31. The fixation between the two first columns 21 and the first beam 22 and the fixation between the two second columns 31 and the second beam 32 is conducive to the stability and firmness of the main structure of the device and the firm connection.

[0025] like Figures 1 to 4 As shown, a display 6 is mounted on one of the columns of the first support frame 2 for controlling the operation of the device.

[0026] In the present invention, the display 6 is the prior art.

[0028] like Figures 1 to 4 As shown, the bottom of the AGV trolley 5 also has a plurality of casters 7.

[0029] In the utility model, the casters are prior art.

[0030] The AGV trolley 5 is conveniently moved by a plurality of casters 7 arranged at the bottom.

[0031] like Figures 1 to 4 As shown, the mechanical arm 42 has an outer sheet metal shell. By outer sheet metal shell, the appearance of the device body is both practical and aesthetic.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. At the same time, the meaning of "and / or" appearing in the full text is that it includes three schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
