Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a new energy vehicle panel detection method, device, computer equipment and storage medium. Background Art
[0002] In recent years, the demand for new energy vehicle panels has been increasing, and the quality requirements are extremely high, which brings risks to the quality of finished product shipments. The inspection plan currently adopted by FQC is: AVI machine inspection + personnel VRS workstation inspection + secondary manual visual inspection + FQA random inspection. Through AVI machine inspection and multiple manual visual inspection processes, the risk of defective products flowing out can be reduced.
[0003] However, there are still four problems in the traditional visual inspection process:
[0004] 1. For new energy vehicle panels, multiple visual inspection processes are set up, which has low inspection efficiency and high manpower requirements;
[0005] 2. For defects on the inner wall of the hole, the currently used AVI cannot detect all aspects due to the existence of blind spots. In addition, personnel need to take photos of the hole to find such defects during visual inspection, which is difficult and inefficient. There is a high risk of defect leakage, and functional defects such as no copper in the hole cannot be intercepted 100%;
[0006] 3. Since new energy vehicle boards are generally zero-defect boards with extremely strict appearance requirements, the AVI parameters are also set very strictly, resulting in a large number of false points, which greatly reduces the inspection efficiency of the VRS workstation;
[0007] 4. When customer complaints about quality abnormalities occur, it is impossible to trace back to the scanned images of the defective boards, which causes trouble for quality analysis and improvement. Summary of the invention

[0039] S100: Obtain hole point recognition parameters of a new energy vehicle plate.
[0040] In this embodiment, the hole point identification parameter is the identification feature of the hole points on the board of the new energy vehicle board, that is, the hole point identification parameter is the distribution of the hole points on the board of the new energy vehicle board, that is, the hole point identification parameter corresponds to the size, shape and other states of the hole points on the board of the new energy vehicle board. By collecting the hole point identification parameters, it is convenient to determine the position and distribution of each hole on the current board of the new energy vehicle board, thereby facilitating the subsequent detection of true and false points of the hole points on the board of the new energy vehicle board.
[0041] S200: performing hole filtering processing on the hole point recognition parameters and the preset hole point parameters to obtain a hole point lack-filtering differential value.
[0042] In this embodiment, the hole point identification parameter is the identification feature of the hole points on the board of the new energy vehicle board, that is, the hole point identification parameter is the distribution of the hole points on the board of the new energy vehicle board, that is, the hole point identification parameter corresponds to the size, shape and other states of the hole points on the board of the new energy vehicle board.

The hole point identification parameter and the preset hole point parameter are subjected to hole filtering processing, which is to determine the difference between the hole point identification parameter and the preset hole point parameter, so as to obtain the self-distribution and morphological difference between the hole points on the board of the new energy vehicle board and the standard, that is, the difference reflected by the hole point lack filter difference value.
[0043] S300: Sending a hole point filter alarm signal to a vehicle plate quality inspection system according to the hole point deficiency filter differential value to adjust the true or false state of the hole points of the new energy vehicle plate.
[0044] In this embodiment, the hole point missing filter differential value is obtained based on the hole point identification parameter and the preset hole point parameter. The hole point identification parameter is the identification feature of the hole point on the board of the new energy vehicle board, that is, the hole point identification parameter is the distribution of the hole points on the board of the new energy vehicle board, that is, the hole point identification parameter corresponds to the size, shape and other states of the hole points on the board of the new energy vehicle board. By collecting the hole point identification parameter, it is convenient to determine the position and distribution of each hole on the current board of the new energy vehicle board, so as to facilitate the subsequent detection of true and false points of the hole points on each board of the new energy vehicle board. The preset hole point parameter is the standard identification feature of the hole point on the board of the new energy vehicle board, that is, the preset hole point parameter is the standard distribution of the hole points on the board of the new energy vehicle board, that is, the preset hole point parameter corresponds to the specified state of the size, shape and other states of the hole points on the board of the new energy vehicle board. The hole point identification parameters and the preset hole point parameters are subjected to hole filtering processing to determine the difference between the hole point identification parameters and the preset hole point parameters, so as to obtain the distribution of the hole points on the board of the new energy vehicle board and the degree of difference between the morphology and the standard, that is, the difference reflected by the hole point lack filtering differential value. After determining the hole point lack filtering differential value, the degree of difference between the current on-board hole points of the new energy vehicle board and the standard on-board hole points can be known, so as to determine the true and false hole points of the current on-board hole points of the new energy vehicle board, thereby facilitating the determination of whether the current on-board hole points of the new energy vehicle board are filtered or retained, and further facilitating the improvement of the detection efficiency of the current on-board hole points of the new energy vehicle board.
[0045] In the above embodiment, after the hole point identification parameters are collected, the positions and distribution of the holes on the current board of the new energy vehicle board are determined, and then the hole point identification parameters are compared with the standard hole point identification parameters to facilitate determination of the difference between the current board hole points and the standard board hole points. Finally, based on the above difference value, the authenticity of the corresponding board hole points is sent to the vehicle board quality inspection system to facilitate determination of the authenticity of the board hole points of the new energy vehicle board, thereby facilitating filtering out false points and effectively improving the inspection efficiency of false points.
[0046] In one of the embodiments, the obtaining of the hole point identification parameters of the new energy vehicle board includes: obtaining the number of inner angles of the hole points of the new energy vehicle board. In this embodiment, the hole point identification parameters are the identification features of the hole points on the board of the new energy vehicle board, that is, the hole point identification parameters are the distribution of the hole points on the board of the new energy vehicle board, that is, the hole point identification parameters correspond to the size, shape and other states of the hole points on the board of the new energy vehicle board. By collecting the hole point identification parameters, it is convenient to determine the position and distribution of each hole on the current board of the new energy vehicle board, so as to facilitate the subsequent detection of true and false points of the hole points on each board of the new energy vehicle board. The hole point identification parameter is the number of inner angles of the hole points of the new energy vehicle board, and the number of inner angles of the hole points is the number of angles in the hole of the hole points on the board of the new energy vehicle board, that is, the number of inner angles of the hole points is the number of angles formed by the edges of the hole points on the board of the new energy vehicle board, and specifically, the number of inner angles of the hole points is the number of internal acute angles of the hole points on the board of the new energy vehicle board.
[0047] Furthermore, the hole point identification parameters and the preset hole point parameters are subjected to hole filtering processing to obtain the hole point missing filter differential value, including: obtaining the inner angle difference between the inner angle number of the hole point and the preset inner angle number to obtain the inner angle difference of the hole point. In this embodiment, the hole point identification parameters are the identification features of the hole points on the board of the new energy vehicle board, that is, the hole point identification parameters are the distribution of the hole points on the board of the new energy vehicle board, that is, the hole point identification parameters correspond to the size, shape and other states of the hole points on the board of the new energy vehicle board. By collecting the hole point identification parameters, it is convenient to determine the position and distribution of each hole on the current board of the new energy vehicle board, thereby facilitating the subsequent detection of true and false points of the hole points on each board of the new energy vehicle board. The hole point identification parameter is the number of internal angles of the hole points of the new energy vehicle board. The number of internal angles of the hole points is the number of angles in the holes of the hole points on the board of the new energy vehicle board, that is, the number of internal angles of the hole points is the number of angles formed by the edges of the hole points on the board of the new energy vehicle board. Specifically, the number of internal angles of the hole points is the number of internal acute angles of the hole points on the board of the new energy vehicle board. The preset number of internal angles is the number of standard internal angles of the hole points on the board of the new energy vehicle board, that is, the preset number of internal angles is the number of specified angles formed by the edges of the hole points on the board of the new energy vehicle board. The difference between the number of internal angles of the hole points and the preset number of internal angles is obtained to determine the degree of difference in the number of internal angles of the hole points on the board of the new energy vehicle board, so as to determine the authenticity of the hole points on the board of the new energy vehicle board.
[0048] Furthermore, the hole point filter signal is sent to the vehicle plate quality inspection system according to the hole point missing filter differential value to adjust the true and false status of the hole points of the new energy vehicle plate, including: detecting whether the hole point internal angle difference is greater than or equal to the preset internal angle difference; when the hole point internal angle difference is greater than or equal to the preset internal angle difference, sending a hole false point filter signal to the vehicle plate quality inspection system. In this embodiment, the hole point identification parameter is the identification feature of the hole point on the board of the new energy vehicle plate, that is, the hole point identification parameter is the distribution of the hole points on the board of the new energy vehicle plate, that is, the hole point identification parameter corresponds to the size, shape and other states of the hole points on the board of the new energy vehicle plate. By collecting the hole point identification parameters, it is convenient to determine the position and distribution of each hole on the current board of the new energy vehicle plate, so as to facilitate the subsequent detection of true and false points of each hole point on the board of the new energy vehicle plate. The hole point identification parameter is the number of internal angles of the hole points of the new energy vehicle board. The number of internal angles of the hole points is the number of angles in the holes of the hole points on the board of the new energy vehicle board, that is, the number of internal angles of the hole points is the number of angles formed by the edges of the hole points on the board of the new energy vehicle board. Specifically, the number of internal angles of the hole points is the number of internal acute angles of the hole points on the board of the new energy vehicle board. The preset number of internal angles is the number of standard internal angles of the hole points on the board of the new energy vehicle board, that is, the preset number of internal angles is the number of specified angles formed by the edges of the hole points on the board of the new energy vehicle board. The difference between the number of internal angles of the hole points and the preset number of internal angles is obtained to determine the degree of difference in the number of internal angles of the hole points on the board of the new energy vehicle board, so as to determine the authenticity of the hole points on the board of the new energy vehicle board. The hole point internal angle difference is the difference between the number of internal angles of the hole points on the board of the new energy vehicle board and the standard number of internal angles. The preset internal angle difference is the standard deviation value of the number of internal angles of the hole points on the board of the new energy vehicle board. The hole point internal angle difference is greater than or equal to the preset internal angle difference, indicating that the number of internal angles of the hole points on the board of the new energy vehicle board is too large, that is, the number of hole edge gaps of the hole points on the board of the new energy vehicle board has increased, that is, the hole points on the board of the new energy vehicle board are false points, and a hole false point filtering signal is sent to the vehicle board quality inspection system to facilitate the detection of the current on-board hole points of the new energy vehicle board as false points on the board, thereby facilitating the filtering of the current on-board hole points of the new energy vehicle board.
[0049] In another embodiment, when the internal angle difference of the hole point is less than the preset internal angle difference, a hole true point reporting signal is sent to the vehicle plate quality inspection system so that the current hole point on the new energy vehicle plate is regarded as the true point on the plate, that is, the current hole point on the new energy vehicle plate is a normal drilling hole.
[0050] In one of the embodiments, the acquisition of the hole point identification parameters of the new energy vehicle board includes: acquiring the inner diameter of the hole points of the new energy vehicle board. In this embodiment, the hole point identification parameters are the identification features of the hole points on the board of the new energy vehicle board, that is, the hole point identification parameters are the distribution of the hole points on the board of the new energy vehicle board, that is, the hole point identification parameters correspond to the size, shape and other states of the hole points on the board of the new energy vehicle board. By collecting the hole point identification parameters, it is convenient to determine the position and distribution of each hole on the current board of the new energy vehicle board, so as to facilitate the subsequent detection of true and false points of the hole points on each board of the new energy vehicle board. The hole point identification parameter is the inner diameter of the hole point of the new energy vehicle board, and the hole point inner diameter is the inner diameter of the hole point on the board of the new energy vehicle board, that is, the hole point inner diameter is the size of the hole point formed by the edge of the hole point on the board of the new energy vehicle board. Specifically, the hole point inner diameter is the internal average diameter of the hole point on the board of the new energy vehicle board.
[0051] Further, the hole point identification parameter and the preset hole point parameter are subjected to hole filtering processing to obtain the hole point missing filter differential value, including: obtaining the diameter difference between the hole point inner diameter and the preset inner diameter to obtain the hole point inner diameter difference. In this embodiment, the hole point identification parameter is the identification feature of the hole point on the board of the new energy vehicle board, that is, the hole point identification parameter is the distribution of the hole point on the board of the new energy vehicle board, that is, the hole point identification parameter corresponds to the size, shape and other states of the hole point on the board of the new energy vehicle board. By collecting the hole point identification parameter, it is convenient to determine the position and distribution of each hole on the current board of the new energy vehicle board, so as to facilitate the subsequent detection of true and false points of the hole points on each board of the new energy vehicle board. The hole point identification parameter is the inner diameter of the hole point of the new energy vehicle board, and the hole point inner diameter is the inner diameter of the hole point on the board of the new energy vehicle board, that is, the hole point inner diameter is the size of the hole point formed by the edge of the hole point on the board of the new energy vehicle board, and specifically, the hole point inner diameter is the internal average diameter of the hole point on the board of the new energy vehicle board. The preset inner angle number is the standard inner hole diameter of the hole point on the board of the new energy vehicle board, that is, the preset inner angle number is the specified hole point size formed by the edge of the hole point on the board of the new energy vehicle board. The diameter difference between the inner diameter of the hole point and the preset inner diameter is obtained to determine the degree of difference in the internal diameter of the hole point on the board of the new energy vehicle board, which is convenient for determining the authenticity of the hole point on the board of the new energy vehicle board.
[0052] Furthermore, the hole point filter signal is sent to the vehicle plate quality inspection system according to the hole point missing filter differential value to adjust the true and false status of the hole points of the new energy vehicle plate, including: detecting whether the hole point inner diameter difference is greater than or equal to the preset inner diameter difference; when the hole point inner angle difference is less than the preset inner diameter difference, a hole true point reporting signal is sent to the vehicle plate quality inspection system. In this embodiment, the hole point identification parameter is the identification feature of the hole points on the board of the new energy vehicle plate, that is, the hole point identification parameter is the distribution of the hole points on the board of the new energy vehicle plate, that is, the hole point identification parameter corresponds to the size, shape and other states of the hole points on the board of the new energy vehicle plate. By collecting the hole point identification parameters, it is convenient to determine the position and distribution of each hole on the current board of the new energy vehicle plate, so as to facilitate the subsequent detection of true and false points of the hole points on each board of the new energy vehicle plate. The hole point identification parameter is the inner diameter of the hole point of the new energy vehicle board. The inner diameter of the hole point is the inner diameter of the hole point on the board of the new energy vehicle board, that is, the inner diameter of the hole point is the size of the hole point formed by the edge of the hole point on the board of the new energy vehicle board. Specifically, the inner diameter of the hole point is the internal average diameter of the hole point on the board of the new energy vehicle board. The preset inner angle number is the standard inner diameter of the hole point on the board of the new energy vehicle board, that is, the preset inner angle number is the specified hole point size formed by the edge of the hole point on the board of the new energy vehicle board. The diameter difference between the inner diameter of the hole point and the preset inner diameter is obtained to determine the degree of difference in the internal diameter of the hole point on the board of the new energy vehicle board, which is convenient for determining the authenticity of the hole point on the board of the new energy vehicle board. The hole point inner diameter difference is the difference between the inner diameter of the hole point on the board of the new energy vehicle board and the standard inner diameter. The preset inner diameter difference is the standard deviation value of the inner diameter of the hole point on the board of the new energy vehicle board. The hole point inner diameter difference is smaller than the preset inner diameter difference, indicating that the inner diameter of the hole point on the board of the new energy vehicle board is shorter, that is, the hole area of the hole point on the board of the new energy vehicle board is smaller, which meets the drilling size of the new energy vehicle board, that is, the hole point on the board of the new energy vehicle board is a true point, and a hole true point reporting signal is sent to the vehicle board quality inspection system to facilitate the detection of the current hole point on the board of the new energy vehicle board as a true point on the board, so as to facilitate the current hole point on the board of the new energy vehicle board to be regarded as a normal drilling.
[0053] In another embodiment, when the inner angle difference of the hole point is greater than or equal to the preset inner diameter difference, a hole false point filtering signal is sent to the vehicle plate quality inspection system, and the inner diameter difference of the hole point is greater than or equal to the preset inner diameter difference, indicating that the inner diameter of the on-board hole point of the new energy vehicle plate is too long, that is, the hole area of the on-board hole point of the new energy vehicle plate is too large, which does not conform to the standard size of the on-board hole point of the new energy vehicle plate, that is, the on-board hole point of the new energy vehicle plate is a false point, and a hole false point filtering signal is sent to the vehicle plate quality inspection system to facilitate the detection of the current on-board hole point of the new energy vehicle plate as a false point on the plate, thereby facilitating the filtering of the current on-board hole point of the new energy vehicle plate.
[0054] During the actual inspection process of the new energy vehicle board, the hole points on the board of the new energy vehicle board are subjected to analysis processing of the hole point identification parameters, and the true and false points are judged based on the hole point identification parameters, so as to determine whether the hole points on the board of the new energy vehicle board are drilled holes, thereby facilitating the filtering of false points and avoiding the situation where false points are used as normal drilling holes and cause waste boards.
[0055] However, even after determining that the hole point on the board of the new energy vehicle board is a true point, there are still hole wall defects at the hole point on the board of the new energy vehicle board, that is, the hole wall at the hole point on the board of the new energy vehicle board is incomplete, and it is still easy to produce a large number of defective products.
[0056] In order to improve the probability of good products of the new energy vehicle plate, the hole point filter signal is sent to the vehicle plate quality inspection system according to the hole point defect filter differential value to adjust the true and false state of the hole points of the new energy vehicle plate, and then it also includes:
[0057] Acquire a true point hole image of the new energy vehicle panel;
[0058] Acquire the true point depth-to-diameter ratio according to the true point aperture image;
[0059] Detecting whether the true point aspect ratio is greater than or equal to a preset aspect ratio;
[0060] When the true point depth-to-diameter ratio is greater than or equal to the preset depth-to-diameter ratio, a true point hole wall intact signal is sent to the vehicle plate quality inspection system.
[0061] In this embodiment, the true point hole photo image is an image of the true point of the drilling hole on the new energy vehicle board, that is, the true point hole photo image is an image of the light in the hole corresponding to the true point on the new energy vehicle board, that is, the true point hole photo image corresponds to the situation in the hole of the true point on the new energy vehicle board, and the true point hole photo image is used to show the surface structure of each position in the hole of the true point on the new energy vehicle board. According to the surface situation in the hole reflected by the true point hole photo image, the inner wall situation of the true point of the drilling hole on the new energy vehicle board is analyzed, so as to facilitate the collection of the inner wall surface state of the true point of the drilling hole on the new energy vehicle board. The true point depth-to-diameter ratio is obtained based on the true point hole photo image. The true point depth-to-diameter ratio is the ratio between the drilling depth and the drilling diameter of the true point of the drilling hole on the new energy vehicle board. The true point depth-to-diameter ratio is used to reflect the completeness of the drilling of the true point of the drilling hole on the new energy vehicle board. The preset depth-to-diameter ratio is the drilling depth of the true point of the drilling hole on the new energy vehicle board and the drilling diameter. The standard ratio between the diameters, the true point depth-to-diameter ratio is greater than or equal to the preset depth-to-diameter ratio, indicating that the ratio of the depth to the diameter of the current drilling true point on the new energy vehicle board reaches the specified ratio, that is, it indicates that the drilling parameters of the current drilling true point on the new energy vehicle board reach the preset standard, that is, it indicates that the internal hole wall of the current drilling true point on the new energy vehicle board is intact. At this time, a true point hole wall intact signal is sent to the vehicle board quality inspection system to facilitate the detection of the hole wall condition of the current drilling true point on the new energy vehicle board, so as to improve the product quality rate of the new energy vehicle board.
[0062] Furthermore, the detecting whether the true point aspect ratio is greater than or equal to a preset aspect ratio further includes:
[0063] When the true point depth-to-diameter ratio is less than the preset depth-to-diameter ratio, obtaining the aperture illumination tilt angle of the new energy vehicle panel;
[0064] Detecting whether the aperture illumination inclination angle is greater than or equal to a preset inclination angle;
[0065] When the aperture illumination inclination angle is greater than or equal to the preset inclination angle, an aperture illumination difference subtraction signal is sent to the vehicle plate quality inspection system to reduce the aperture illumination incident angle to the new energy vehicle plate.
[0066] In this embodiment, the depth-to-diameter ratio of the true point is less than the preset depth-to-diameter ratio, indicating that the ratio of the depth to the diameter of the current drilling true point on the new energy vehicle board has not reached the specified ratio, that is, it indicates that the drilling parameters of the current drilling true point on the new energy vehicle board are lower than the preset standard, that is, it indicates that the internal hole wall illumination of the current drilling true point on the new energy vehicle board is incomplete, and there are areas of the hole wall that lack light illumination, which easily leads to defects in the hole wall. In order to reduce the occurrence of such situations, the hole illumination inclination angle of the new energy vehicle board is obtained. The hole illumination inclination angle is the hole illumination incident angle of the new energy vehicle board. Specifically, the hole illumination inclination angle is the angle between the illumination light toward the new energy vehicle board and the normal perpendicular to the surface of the new energy vehicle board. The hole illumination inclination angle is used to reflect the inclination of the light irradiating the true point hole wall on the new energy vehicle board. The hole illumination inclination angle is greater than or equal to the preset inclination angle, indicating that the light irradiating the true point hole wall on the new energy vehicle board is too inclined, that is, it indicates that the true point corresponding to the new energy vehicle board is too large. The irradiation light in the hole does not illuminate the bottom of the hole. At this time, part of the hole wall corresponding to the true point on the new energy vehicle board is not illuminated, and a hole illumination difference subtraction signal is sent to the vehicle board quality inspection system to reduce the hole illumination incident angle of the new energy vehicle board. For example, the hole illumination inclination angle is gradually reduced in an arithmetic progression so that all the hole walls corresponding to the true point on the new energy vehicle board are illuminated, so as to illuminate the hole walls corresponding to the true point on the new energy vehicle board in all directions without blind spots, thereby facilitating the all-round and non-dead-angle illumination of the hole walls corresponding to the true point on the new energy vehicle board, thereby facilitating the all-round and non-dead-angle display of the hole wall defects corresponding to the true point on the new energy vehicle board through images.
[0067] In another embodiment, when the hole illumination inclination angle is less than a preset inclination angle, a true point full illumination signal is sent to the vehicle plate quality inspection system to determine that the hole wall corresponding to the true point on the new energy vehicle plate is displayed as a complete image, which is regarded as the required hole wall on the new energy vehicle plate without defects, that is, a qualified drilled hole.
[0068] In order to improve the drilling positioning accuracy of the new energy vehicle plate, the acquisition of the hole point identification parameters of the new energy vehicle plate also includes the following steps:
[0069] Acquire a front panel window image of the new energy vehicle panel;
[0070] Acquire the front panel window opening area according to the front panel window opening image;
[0071] Detecting whether the window opening area of the front plate target is greater than or equal to a preset window opening area;
[0072] When the front plate target window area is greater than or equal to the preset window area, a target positioning signal is sent to the vehicle plate quality inspection system to obtain the drilling starting target coordinates of the new energy vehicle plate.
[0073] In this embodiment, the front panel window image is a panel surface image of the previous panel of the new energy vehicle panel that needs to be opened, that is, the front panel window image is a panel window image before the new energy vehicle panel needs to be opened, that is, the front panel window image corresponds to the window situation on the front panel of the new energy vehicle panel. By analyzing the image of the front panel window image, it is easy to obtain the window situation on the front panel of the new energy vehicle panel, so as to facilitate the determination of the window size on the front panel of the new energy vehicle panel, that is, the front panel window area. Specifically, the window corresponding to the preset window area is 8×8mm. The preset window opening area is the standard window opening size on the front panel of the new energy vehicle panel, and the front panel target window opening area is greater than or equal to the preset window opening area, indicating that the window opening size on the front panel of the new energy vehicle panel has reached the standard window opening size, that is, it indicates that the area corresponding to the front panel window opening image is the target area, and a target positioning signal is sent to the vehicle panel quality inspection system to obtain the starting target coordinates of the drilling of the new energy vehicle panel, so as to facilitate the positioning of the drilling target of the current panel of the new energy vehicle panel, thereby facilitating the determination of the starting target position of laser drilling, thereby improving the blind hole alignment accuracy on the new energy vehicle panel.
[0074] In another embodiment, when the window opening area of the front plate target is smaller than the preset window opening area, a drilling withdrawal signal is sent to the vehicle plate quality inspection system to exit the current drilling process.
[0075] Further, when the window opening area of the front plate target is greater than or equal to the preset window opening area, a target positioning signal is sent to the vehicle plate quality inspection system to obtain the drilling starting target coordinates of the new energy vehicle plate, and then it also includes:
[0076] Acquiring the target window aperture according to the front plate window image;
[0077] Detecting whether the target window aperture matches the preset window aperture;
[0078] When the target window aperture matches the preset window aperture, an inner layer burning signal is sent to the vehicle plate quality inspection system to perform inner layer hollow copper processing in an area corresponding to the drilling start target coordinates.
[0079] In this embodiment, the target window aperture is the size of the window hole in the target window area of the new energy vehicle board, that is, the target window aperture corresponds to the target window hole of the new energy vehicle board, which is convenient for determining the aperture of the window hole in the target window area of the new energy vehicle board, thereby facilitating the determination of the target starting position of the new energy vehicle board to improve the drilling accuracy of the new energy vehicle board. The preset window opening aperture corresponds to the preset window opening area one by one, and the target window opening aperture matches the preset window opening aperture. Specifically, the preset window opening aperture is 2 mm, indicating that the window opening hole in the target window opening area of the new energy vehicle board is the same as the standard window opening hole, that is, the window opening size in the target window opening area of the new energy vehicle board is consistent with the window opening size corresponding to the standard target, and an inner layer burning signal is sent to the vehicle board quality inspection system to perform inner layer empty copper processing in the area corresponding to the drilling start target coordinates, so as to facilitate inner layer burning on the previous board that needs to be drilled in the new energy vehicle board, so that the inner layer copper layer in the target area of the previous board that needs to be drilled in the new energy vehicle board is hollowed out, further improving the drilling alignment accuracy, so that the alignment accuracy between the previous board that needs to be drilled and the current board in the new energy vehicle board reaches ±10μm.
[0080] In another embodiment, when the target window aperture does not match the preset window aperture, a non-target signal is sent to the vehicle panel quality inspection system to stop processing the inner layer empty copper in the area corresponding to the drilling start target coordinates, thereby effectively avoiding damage to the new energy vehicle panel.
[0081] The above-mentioned various preset variables are all set in the database for timely retrieval, and different preset variables are placed in different storage units, that is, in different storage stacks. Moreover, the true point aperture image, true point depth-to-diameter ratio, aperture inclination angle and front plate window image can be collected through corresponding detectors, for example, through the image collector in the aperture point acquisition module.

[0083] In this embodiment, after the hole point acquisition module collects the hole point identification parameters, the position and distribution of each hole on the current board of the new energy vehicle board are determined, and then the point filter processing module compares the hole point identification parameters with the standard hole point identification parameters to facilitate determining the difference between the current hole points on the board and the standard hole points on the board. Finally, the hole point filter output module sends the corresponding on-board hole point authenticity to the vehicle board quality inspection system based on the above difference value, which is convenient for determining the authenticity of the hole points on each board of the new energy vehicle board, thereby facilitating the filtering out of false points, effectively improving the inspection efficiency of false points.
