[0051] The invention provides a pipe segment capturing device.

[0052] See also Figures 1 to 6 In one embodiment of the present invention, the pipe segment capturing device includes a terminal 100, a positioning mechanism 200 and a capturing mechanism 300. A placement space 210 for placing the pipe segment to be detected is formed in the positioning mechanism 200. A plurality of positioning positions 220 spaced apart along the circumferential direction are formed on the positioning mechanism 200. The capturing mechanism 300 is arranged above the positioning mechanism 200. The capturing mechanism 300 is communicatively connected with the terminal 100. The capturing mechanism 300 can capture the pipe segment to be detected and / or any positioning position 220. The terminal 100 can establish a basic coordinate system of the detection space when controlling the capturing mechanism 300 to capture at least one positioning position 220, and the terminal 100 controls the capturing mechanism 300 to capture the pipe segment to be detected located in the basic coordinate system to determine the placement position of the pipe segment to be detected.

[0053] In this embodiment, by using the terminal 100, the positioning mechanism 200 and the capturing mechanism 300, when in use, the capturing mechanism 300 is used to capture at least three positioning positions 220 on the positioning mechanism 200 and transmit the first spatial coordinates of each captured positioning position 220 to the terminal 100, so that the terminal 100 establishes a basic coordinate system according to the multiple first spatial coordinates collected. At the same time, the capturing mechanism 300 can capture the pipe segment to be inspected in the basic coordinate system to determine the placement position of the pipe segment to be inspected, so that the present invention can determine the position of the pipe segment to be inspected in specific use, and thus the present invention can accurately determine the position of the pipe segment to be inspected in the placement space 210 in specific use, and thus can achieve that in the process of inspecting the pipe segment to be inspected, the position of the pipe segment in the inspection space can be determined according to the mold and other equipment, so that the influence of the non-prefabricated pipe segment's own structure on the inspection accuracy of the prefabricated pipe segment can be avoided, thereby improving the inspection accuracy of the surface quality of the prefabricated pipe segment.

[0054] In some specific embodiments, the positioning mechanism 200 includes a first positioning component 230 and a plurality of second positioning components 240, the first positioning component 230 is arranged around the periphery of the placement space 210, and a plurality of positioning positions 220 are distributed at intervals along the circumferential direction on the top of the first positioning component 230, and the first positioning component 230 is also provided with a plurality of installation positions 250 distributed at intervals with each positioning position 220, the capture mechanism 300 can transmit the first spatial coordinates of at least three positioning positions 220 captured and obtained to the terminal 100, so that the terminal 100 establishes a basic coordinate system of the detection space, and the number of the plurality of second positioning components 240 is consistent with that of the installation positions 250 and is the same A corresponding arrangement is adopted, and each second positioning component 240 is arranged toward the placement space 210 and can emit separation light toward the placement space 210. Multiple separation light rays intersect and interweave in pairs in the placement space 210 to form multiple adjacent positioning grids. The pipe segment to be detected can enter the placement space 210 and intercept the separation light rays passing through it; the capture mechanism 300 can capture and obtain the second spatial coordinates of the interception position of each separation light of the pipe segment to be detected when the pipe segment to be detected intercepts the separation light, and the capture mechanism 300 can transmit all the second spatial coordinates to the terminal 100, so that the terminal 100 maps all the second spatial coordinates to the basic coordinate system to determine the placement position of the pipe segment to be detected.

[0055] In this embodiment, by setting a first positioning component 230 and a plurality of second positioning components 240, when in use, the first positioning component 230 is arranged around the outer periphery of the placement space 210, and a plurality of positioning positions 220 are distributed at intervals along the circumferential direction on the top of the first positioning component 230, and at the same time, the number of the second positioning components 240 and the positioning positions 220 are consistent and arranged one-to-one, and the set capture mechanism 300 is used to capture and obtain the first space coordinates of at least three first positioning positions 220, and the capture mechanism 300 transmits all the obtained first space coordinates to the terminal 100, so that the terminal 100 can establish a basic coordinate system of the placement space 210 according to the received multiple first space coordinates; at the same time, the set capture mechanism 300 is used to capture and obtain the second space coordinates of the truncation position of the to-be-detected pipe segment for each separation light when the to-be-detected pipe segment truncates the separation light, and the capture mechanism 300 can transmit all the second space coordinates to the terminal 100, so that the terminal 100 can map all the second space coordinates to the basic coordinate system to determine the placement position of the to-be-detected pipe segment. Therefore, the present invention can realize the function of positioning the placement position of the pipe segment to be inspected in the placement space 210 by using the cooperation of the set capture mechanism 300 with the first positioning component 230 and the plurality of second positioning components 240 during specific implementation, and can realize the positioning of the prefabricated pipe segment placed in the placement space 210 without the aid of a mold or other structures when positioning the prefabricated pipe segment, thereby avoiding the defect that the surface quality detection accuracy of the prefabricated pipe segment is affected due to the existence of external equipment, and improving the detection accuracy when the surface quality of the prefabricated pipe segment is detected. At the same time, since the capture mechanism 300 has been used to cooperate with the first positioning component 230 and the second positioning component 240 to position the pipe segment to be inspected placed in the placement space 210 before the detection, the detection equipment does not need to search for the prefabricated pipe segment in the placement space 210 when the surface quality of the prefabricated pipe segment is detected, thereby reducing the working beat of the detection equipment and improving the detection efficiency when the surface quality of the prefabricated pipe segment is detected.

[0056] It should be particularly and clearly stated that, in this embodiment, when the second positioning component 240 of the example emits a separation light into the placement space 210, it can only emit one light into the placement space 210, or it can simultaneously emit multiple spaced light rays in the vertical direction. In some improved embodiments, the second positioning component 240 of the example preferably emits a separation light by simultaneously emitting multiple spaced separation light rays in the vertical direction. When multiple separation light rays are emitted from the same second positioning component 240, each separation light ray should be arranged in a horizontal direction, and the separation light ray at the bottom layer should be at the lowest position of the prefabricated pipe segment, and the top position of each separation light ray should be flush with the highest position of the prefabricated pipe segment. Through this setting, the height and thickness of the prefabricated pipe segment can be determined simultaneously during the specific implementation of the present invention. Of course, it should be further clarified that, in this embodiment, the method of emitting separation light from the second positioning component 240 of the example can directly use the existing technology, and no improvement design is made in this embodiment, so it will not be described one by one here.

[0057] Of course, it should also be made clear that, in the present embodiment, all the second positioning components 240 are capable of emitting a plurality of separated light beams spaced vertically, and the topmost layer of separated light beams emitted by all the second positioning components 240 into the placement space 210 are in the same plane as the highest point of the prefabricated pipe segment, and the bottommost layer of separated light beams emitted by all the second positioning components 240 into the placement space 210 are in the same plane as the lowest point of the prefabricated pipe segment.

[0058] In some preferred embodiments, the second positioning component 240 includes a mounting base 241 and a first light source 243 component 242, the mounting base 241 is installed at the mounting position 250, and the light emitting end of the first light source 243 component 242 is set toward the placement space 210, and the light source 243 generated by the first light source 243 component 242 can be emitted into the placement space 210 through the light emitting end to form separated light.

[0063] The light-transmitting mirror 245 is installed at the light transmission hole. The light generated by the light source 243 is focused by the focusing element 244 and emitted from the light transmission hole to form a separated light.

[0064] In this embodiment, by setting a light source 243, a focusing element 244 and a light-transmitting mirror 245, when in use, by utilizing the set light source 243, the focusing element 244 and the light-transmitting mirror 245, the present invention can ensure that the separated light incident into the placement space 210 has a good focusing effect during specific use, can avoid scattering of the separated light, ensure the concentration of the separated light, and improve the positioning accuracy when positioning the prefabricated pipe segment.

[0065] It should be particularly and clearly stated that, in this embodiment, the light source 243 is preferably an infrared light source 243 with a high concentration. The focusing element 244 is preferably a focusing lens.

[0067] In this embodiment, by providing the light emission channel 246, the present invention can use the light emission channel 246 to guide the light focused by the focusing member 244, thereby ensuring the concentration of the separated light. At the same time, in specific use, multiple light emission channels 246 spaced apart in the vertical direction can also be provided, and a light-transmitting mirror 245 is installed in each light emission channel 246, thereby enabling the present invention to simultaneously inject multiple separated light rays spaced apart in the vertical direction into the placement space 210 during specific implementation, thereby ensuring the stability and uniformity of the separated light rays.

The terminal 100 can establish a basic coordinate system of the detection space when controlling the capture mechanism 300 to capture at least three positioning positions 220, and at least two positioning columns 233 are installed on each sinking section.

[0073] It should be particularly and clearly stated that, in this embodiment, the purpose of setting the sinking section 236 is to enable the present invention to improve the coordinate accuracy of the basic coordinate system when in use by cooperating with the first column 234 and the second column 235 through the setting of the sinking section 236.

[0084] It should be particularly and clearly stated that, in this embodiment, the exemplary capturer 372 is preferably a device or apparatus capable of realizing light capture and position measurement functions in the prior art. In this embodiment, it is only applied without improving its own structure, so it will not be described in detail here. Of course, in the exemplary embodiment, in order to record the movement of the truss 340 driven by the sliding drive 330, in the specific implementation, a plurality of equally spaced positioning blocks 236 are also provided on one side of the guide rail 320 of the frame 310. In the specific operation, the positioning blocks 236 can be captured instantly by the provided capturer 372 to achieve the purpose of quickly determining the specific position of the truss 340.

[0085] Of course, in this embodiment, it can be further clarified and explained that the example capturer 372 can be but is not limited to an oblique photography camera or a CCD visual camera in the prior art.

[0086] Of course, in order to enable those skilled in the art to further understand the present invention, in this embodiment, when it is specifically implemented, the specific workflow is as follows:

[0087] First, the pipe segment to be inspected is transported to and parked in the placement space 210, and then the sliding drive 330 is controlled to drive the truss 340 to slide along the guide rail 320 to the top of one side of the pipe segment to be inspected, and then the slide 360 ​​installed on the truss 340 is used to drive the capture component 370 to slide along the slide rail 350 to the corner position of the corresponding side of the pipe segment to be inspected. At this corner position, the capture component 370 is controlled by the terminal 100 to capture and obtain at least three positioning columns 233 in the area where the pipe segment to be inspected is located. When the first spatial coordinates of at least three positioning columns 233 are collected, the terminal 100 is used to establish a basic coordinate system that can be applied to the placement space 210, and then the capture component 370 is controlled to capture and obtain the truncation position of each separation light ray truncated by the pipe segment to be inspected in the basic coordinate system, and then the placement position of the pipe segment to be inspected in the placement space 210 can be determined according to the obtained truncation position.

[0088] It should be particularly and clearly stated that, in the present embodiment, the specific process of obtaining the truncation position of each separated light ray is as follows: the capture component 370 is set as an oblique photography camera. When in use, the movement stroke of the truss 340 driven by the sliding drive 330 and the capture component 370 driven by the slide 360 ​​is first transmitted to the terminal 100, and then the length of each separated light ray to the corresponding truncation position determined by the terminal 100 technology capture component 370 is used to determine the coordinates of the truncation position, and then the coordinates of each truncation position are determined, and the coordinates of all truncation positions are combined to obtain the second spatial coordinates to determine the placement position of the pipe segment to be inspected.
