When the installation sets up, the distance that each target ball reference column 3 outwards stretches out is controlled to be diverse to the top of each target ball reference column 3 all is fixed with the target ball (not shown in the figure).
Based on the above description of the structure of the blue light scanning part integrated detection tool, it can be seen that, in the present invention, the part to be detected 5 can be fixed on the bracket body 1 through the fixed support rod 2, and the bracket body 1 can be rotated around the axis extending in the height direction through the rotating base 4, so as to drive the part to be detected 5 to rotate, thereby realizing the turn-over operation of the part to be detected 5.

FIG. 3 schematically shows a flow chart for evaluating the quality of a part using the blue light scanning integrated part inspection tool shown in FIG. 2.
Referring to fig. 3, based on the disclosure of fig. 2, in the present invention, the blue light scanning component integrated inspection tool shown in fig. 2 is used to inspect the component 5 to be inspected so as to evaluate the quality of the component, and the method specifically includes the following steps:
step 100: two parts to be measured 5 are installed on the bracket body 1 by adopting the fixed support rod 2.
Step 200: the bracket body 1 is scanned by adopting blue light scanning equipment, the spatial position of the reference point patch is obtained, and the spatial position of the part to be detected 5 is obtained based on the spatial position of the reference point patch.
In the present embodiment, the bracket body 1 is further provided with a coding point and a scale, the spatial position of the reference point patch is obtained by using a photographic positioning method, and then the spatial position of the component 5 to be measured can be further obtained based on the spatial position of the reference point patch.
In the invention, obtaining the spatial position of the part 5 to be measured can be carried out by relying on ATOS Professional software, a camera, a scale, a reference point patch and a coding point. The identification method can be roughly divided into two steps: 1. and 2, confirming the position relation between the part to be detected 5 and the reference point patch by using a 'photographic positioning method' through the coding point, and determining the position relation between the blue light scanning equipment and the part to be detected 5 through the reference point before scanning.
In the invention, the 'photography positioning method' needs to place a coding point, a reference point and a scale on the surface of the bracket body 1, then surround the scanning area of the part 5 to be measured and the bracket body 1 at different angles, shoot and record the position relation among the coding point, the reference point patch and the scale through a camera, and then construct the space positions of all the reference point patches through computer ATOS Professional software conversion.
The blue light scanning equipment is provided with a binocular camera, the spatial position of the reference point patch can be identified through graphic perception, and the ATOS Professional software can automatically calculate the position relation between the scanner and the part to be measured 5 by comparing the spatial position of the reference point patch positioned by photography and the spatial position of the reference point identified by the blue light scanning equipment.
Step 300: adopt blue light scanning equipment to await measuring part 5 and scan to make the outward appearance face of the part 5 that awaits measuring and the non-outward appearance face of the outward appearance face of dorsad all scanned through rotating bracket body 1.
In the present invention, the support body 1 is rotated by rotating the support body 1, so that the support body 1 rotates around the axis extending along the height direction through the rotating shaft, and the part to be measured 5 is driven to rotate, so that the appearance surface (which can be understood as the surface a in fig. 3) of the part to be measured 5 and the non-appearance surface (which can be understood as the surface B in fig. 3) facing away from the appearance surface are both scanned.
Step 400: and fitting, namely comparing the scanned part surface size point cloud data with the entity three-dimensional data of the part 5 to be detected to obtain deviation data.
And comparing the part surface dimension point cloud data obtained by scanning through the blue light scanning equipment with the entity three-dimensional data of the part 5 to be detected, taking the entity three-dimensional data of the part 5 to be detected as a design standard value, and determining the difference part between the part surface dimension point cloud data obtained by scanning and the design standard value as the deviation of the actual part.
In the invention, through a blue light scanning technology, the point cloud data of the surface size of the part can be collected, and then the point cloud data is compared and analyzed with a theoretical design standard value to obtain the actual deviation of the part 5 to be measured; and then further projecting the scanned part surface size point cloud data onto the actual part to be measured 5 by using laser projection through a virtual reality technology, and marking deviations of different degrees through different colors.
Step 500: and establishing a laser projection coordinate system based on the target ball, and projecting the deviation data onto the part in different colors by adopting a laser projection method.
In this embodiment, the target ball itself is of conventional design, and is selected to be a hemispherical target ball with a diameter of 1.5 inches; because the stability and the uniqueness of the target ball positioning need to be ensured and the sphere center position of the target ball needs to be ensured to be fixed, the target ball positioning columns 3 are designed and processed on the support body, and the support grooves for arranging the target balls are arranged on the target ball positioning columns, so that the circle center position of the target ball is not changed when the target ball is placed on the target ball positioning columns 3 at any angle.
In the invention, a virtual reality technology is adopted, and the position of a target ball in the space can be determined by identifying the sphere center position of the target ball by utilizing virtual reality projection; based on the spatial position of the target ball, a laser projection coordinate system can be further established.
In order to realize high-precision positioning of the target ball and enable projection to better identify the spatial depth of the position of the part to be detected 5, in the blue light scanning part integrated detection tool, the number of the target ball positioning columns 3 which can be preferably arranged is more than or equal to 6; for example, in this embodiment, there are 9 target ball positioning posts 3 extending outwardly at different distances, each having a bracket for receiving 9 target balls having a diameter of 1.5 inches; through the target ball placed on the 9 target ball positioning columns 3, the establishment of a coordinate system can be completed by industrial laser, and for a part 5 to be measured, which is 1m away, the positioning accuracy can meet the requirement of high-precision report projection, wherein the height of the report projection is less than 1 mm.
In the present embodiment, although there is room for randomly taking the distance that the 9 target ball positioning columns 3 extend outward, in order to ensure the accuracy of the subsequent positioning projection, there are two further requirements: 1. the distance of the outward extension of the target ball positioning column 3 is controlled to be more than 0 and less than or equal to 1000 mm; 2. and controlling the distance difference of the outward extension of the two adjacent target ball positioning columns 3 to be larger than 100 mm.
In the actual use process, an operator can confirm the specific control requirements for the target ball positioning column 3 based on the average height of the part 5 to be measured according to actual requirements.
The above two-point control requirements for the target sphere positioning column 3 may be determined based on parameters such as a projection lens, a positioning lens, a tool platform surface size, an object distance, a projection lcd prism, and a positioning lens sensor size, after a trigonometric operation and a lens imaging focal length calculation formula, in this embodiment, the two-point control requirements may specifically include the following steps (1) to (4):
(1) firstly, determining an ideal distance capable of realizing clear projection according to parameters of a projection lens: the projection range and the area of the projection lens are used for determining that the projection lens is 2.5-4 m away from the projection part, and the optimal projection range and effect can be obtained when the projection lens projects downwards in an inclined mode at an angle of 30 degrees; the projector is fixed on a support vertical to the ground, and the ideal height of the projector is 1.25-1.6 m.
(2) And calculating the parameters of the positioning lens to determine that the focal length of the positioning camera lens is 24mm, the size of a photosensitive original of the positioning camera is one half inch, and the size of the photosensitive original is calculated to be 4.8mm in the transverse direction and 6.4mm in the longitudinal direction.
(3) Substituting the positioning parameters in the steps (1) and (2) to obtain the transverse 1436-2298 mm of the position of the positioning lens at 2.5-4 m; the longitudinal direction is 1044mm to 1671 mm.
(4) Verifying the coverage range of the positioning lens: the minimum transverse coverage size of the positioning lens is larger than the maximum width of the bottom plate by 1.2m, the identification of the edge positioning column when the bottom plate is in any rotating position can be completed, and the object distance does not need to be increased.
(5) The distance of the target ball positioning column 3 which is closest to the platform and can be obtained by the longitudinal coverage size is limited to 1044mm, and 1000mm is taken as the maximum limit size of the distance of the target ball positioning column 3 which extends outwards in consideration of manufacturing deviation and bracket size.
Therefore, in the embodiment, virtual circle centers of 9 brackets can be further calculated through GOM (goal object) observation software, three-coordinate information of the virtual circle centers under a whole vehicle coordinate system is exported to projection software, and then a target ball is arranged to complete establishment of a laser projection coordinate system for a virtual reality technology.
Therefore, the establishment of a laser projection coordinate system can be completed; according to the established laser projection coordinate system, the scanned part surface size point cloud data can be imported into industrial laser projection, projection of the surface quality of the part 5 to be measured is achieved through a virtual reality mode, and the quality defect of the part 5 to be measured can be visually seen.
Step 600: and directly judging the quality of the part to be detected according to the color displayed on the part to be detected 5.
In the invention, the quality of the part to be detected can be directly judged according to the color displayed on the part to be detected 5 by further marking the deviation with different degrees through different colors. The positive out-of-tolerance of the surface size of the part to be detected can be represented by a first color, and the negative out-of-tolerance of the surface size of the part to be detected can be represented by a second color different from the first color; and the larger the absolute value of the deviation, the darker the color.
In the present embodiment, the dark red color may be used to indicate the positive out-of-tolerance of the surface size of the part to be measured, the dark blue color may be used to indicate the negative out-of-tolerance of the surface size of the part to be measured, and the darker the color, the larger the absolute value of the deviation.
Therefore, the blue light scanning part integrated detection tool can be used for simultaneously detecting the quality of two parts to be detected, and is simple to implement and high in working efficiency.
In conclusion, the blue light scanning-based part integrated detection tool disclosed by the invention can enable the blue light scanning of the front side and the back side of the part to be more convenient and faster through the structural optimization design; this integrated detection instrument of blue light scanning part only needs reference point paster once of pasting on the support body, can a plurality of parts of repeated scanning, has avoided the waste of reference point paster, improves economic nature greatly.
