[0038] Specifically, please continue to refer to Figure 3As shown, the mobile driving mechanism 3 includes: a linear module 31, a mobile seat 32, a mobile guide rail 33 arranged in the front-to-back direction, and a mobile guide block 34 slidably matched with the mobile guide rail 33. The surface visual detection mechanism 4 and the thickness detection mechanism 5 are both arranged on the mobile seat 32. The mobile seat 32 is arranged on the linear module 31 to drive the mobile seat 32 to move forward and backward. The mobile seat 32 is fixedly connected to the mobile guide block 34. When in use, the linear module 31 is used to drive the mobile seat 32 to move forward and backward, thereby driving the surface visual detection mechanism 4 and the thickness detection mechanism 5 to move forward and backward. In the above process, the mobile guide rail 33 guides the mobile guide block 34.

[0039] In this embodiment, the surface visual detection mechanism 4 is arranged at the rear end of the moving seat 32, and the thickness detection mechanism 5 is arranged at the front end of the moving seat 32; there are two moving guide rails 33 and two moving guide blocks 34, and the two moving guide rails 33 are separated left and right.

[0040] More specifically, if Figure 5 As shown, the surface visual detection mechanism 4 includes: a camera up and down fine-tuning device 41 and a surface camera 42. The surface camera 42 is arranged on the camera up and down fine-tuning device 41 to adjust the up and down position of the surface camera 42. The surface camera 42 is arranged downward and the moving track of the surface camera 42 passes directly above the detection position. The moving seat 32 is provided with a first adjustment rail 321 arranged along the left and right direction and a first adjustment guide block 322 slidably matched with the first adjustment rail 321. The camera up and down fine-tuning device 41 is fixedly connected to the first adjustment guide block 322.

[0041] In this embodiment, there are two first adjustment rails 321, which are separated up and down, and there are at least two first adjustment guide blocks 322. Each camera up and down fine-tuning device 41 is fixedly connected to two first adjustment guide blocks 322. The two first adjustment guide blocks 322 play the role of supporting the camera up and down fine-tuning device 41 at two points.

[0042] More specifically, if Figure 6As shown, the thickness detection mechanism 5 includes: an upper laser displacement sensor 51 and a lower laser displacement sensor 52, the upper laser displacement sensor 51 and the lower laser displacement sensor 52 are arranged opposite to each other up and down, and the moving track of the upper laser displacement sensor 51 and the moving track of the lower laser displacement sensor 52 pass directly above and directly below the detection position respectively; the moving seat 32 is provided with two second adjustment rails 323 arranged in the left and right directions and two second adjustment guide blocks 324 slidably matched with the second adjustment rails 323, and the upper laser displacement sensor 51 and the lower laser displacement sensor 52 are fixedly connected with the two second adjustment guide blocks 324 respectively. When in use, the positions of the upper laser displacement sensor 51 and the lower laser displacement sensor 52 can be adjusted by the cooperation of the second adjustment rails 323 and the second adjustment guide blocks 324.

[0043] In this embodiment, there are four surface visual detection mechanisms 4 and four thickness detection mechanisms 5, and there are eight first adjustment guide blocks 322 and second adjustment guide blocks 324. The four surface visual detection mechanisms 4 and the four thickness detection mechanisms 5 are arranged in a row along the left and right directions. The four surface visual detection mechanisms 4 and the four thickness detection mechanisms 5 cooperate to detect the integrated busbar 100 with a large width. Of course, in other embodiments, the surface visual detection mechanism 4 and the thickness detection mechanism 5 can be set to other numbers.

[0044] Specifically, Figure 7 As shown, the end visual detection mechanism 6 includes: an end camera 61, a three-dimensional position fine-tuning device 62, two light sources 63, a support plate 64, and a light source up-and-down fine-tuning device 65. The end camera 61 is arranged on the three-dimensional position fine-tuning device 62 to adjust the three-dimensional position of the end camera 61. The end camera 61 is arranged toward the detection position. The two light sources 63 are separated up and down and are both located between the end camera 61 and the detection position. The light source 63 is rotatably arranged on the support plate 64 around an axis in the left-right direction. The support plate 64 is arranged on the light source up-and-down fine-tuning device 65 to adjust the up-and-down position of the support plate 64. When in use, the up-and-down, left-and-right, and front-and-back positions of the end camera 61 can be adjusted by using the three-dimensional position fine-tuning device 62; the light angle can be adjusted by rotating the light source 63; and the up-and-down position of the light source 63 can be adjusted by using the light source up-and-down fine-tuning device 65.

When in use, the two end visual detection mechanisms 6 detect different areas of the rear end of the integrated busbar 100 respectively.

[0047] Based on the above multifunctional detection device, the present invention provides a detection method for an integrated busbar, the detection method comprising:

[0048] Step A, placing the integrated busbar 100 at the detection position of the detection table 2;

[0049] Step B: The surface camera 42 of the surface visual inspection mechanism 4 moves from front to back directly above the integrated busbar 100 to take pictures and inspect the components on the upper surface of the integrated busbar 100;

[0050] Step C: The upper laser displacement sensor 51 and the lower laser displacement sensor 52 of the thickness detection mechanism 5 are respectively moved from front to back above and below the integrated busbar 100 to sense and detect the thickness of the aluminum bar 103;

[0051] Step D: the end camera 61 of the end visual detection mechanism 6 takes a picture of the rear end of the integrated busbar 100 to detect the components on the lower surface of the integrated busbar 100;

[0052] The above steps B, C and D are performed simultaneously after step A.

[0053] The following takes the solder joint 1031 in the components on the upper surface of the integrated busbar 100 as an example, and takes the PIN pin in the components at the rear end of the integrated busbar 100 as an example, and describes the detection method by way of example. The detection method specifically includes the following steps:

[0054] Step A, placing the integrated busbar 100 at the detection position of the detection platform 2;

[0055] Step B: The surface camera 42 of the surface visual inspection mechanism 4 moves from front to back just above the integrated busbar 100 to take pictures and inspect the size, quantity and position of the welding points 1031 of the aluminum busbar 103;

[0056] Step C: The upper laser displacement sensor 51 and the lower laser displacement sensor 52 of the thickness detection mechanism 5 are respectively moved from front to back above and below the integrated busbar 100 to sense and detect the thickness of the aluminum bar 103;

[0057] Step D: The end camera 61 of the end visual detection mechanism 6 takes a picture of the rear end of the integrated busbar 100 to detect the size, quantity and position of the PIN pins;

[0058] The above steps B, C and D are performed simultaneously after step A.

[0059] Specifically, in step B and step D, detecting the size, quantity and position of the solder joint 1031 and detecting the size, quantity and position of the PIN needle specifically include the following steps:

[0060] Step 1: Forming the coordinate axis: Select a reference object, find the edge of the reference object in the image by contour matching, and use the edge of the reference object as the baseline;

[0061] Step 2: Identify the target component: dually locate the target component to be detected in the image through contour matching and grayscale matching;

[0062] Step 3: Determine the size, quantity and position of the target component: Calculate the size of the target component based on the contour edge of the target component, count the number of identified target components, determine the position of the target component based on the baseline, and determine whether the number and position of the target component meet the requirements.

[0063] It is worth mentioning that before detection, it is necessary to train the model through learning to determine the contour type and grayscale value range of the reference object and the target element; after acquiring the image, the image can be cropped to form multiple ROI areas, and edge finding, recognition and other operations are all performed in the ROI area.

[0064] The following is an example of detecting the size, quantity and position of solder joint 1031. Please continue to refer to Figure 1 As shown, step A specifically includes the following steps:

[0065] Step 1: Using the nickel sheet 102 as a reference, find the inner edge and front and rear edges of the nickel sheet 102 by contour matching, use the straight line where the inner edge of the nickel sheet 102 is located as the first reference line L1, and use the front and rear edges of the nickel sheet 102 as the second reference line L2 and the third reference line L3;

[0066] Step 2, identifying the solder joint 1031 through contour matching and grayscale matching;

[0067] Step 3, determine whether the diameter of the solder joint 1031 is 0.5-0.9 mm, determine whether the number of solder joints 1031 is six, determine whether the distance between the center of the innermost solder joint 1031 and the first reference line L1 is 9-12.6 mm, determine whether the distance between the frontmost solder joint 1031 and the second reference line L2 is less than 1 mm, and determine whether the distance between the rearmost solder joint 1031 and the third reference line L3 is less than 1 mm. If all the above conditions are met, the number and position of solder joints 1031 meet the requirements.

[0068] When detecting the number and position of PIN pins, the connector can be used as a reference and the PIN pins can be detected referring to the above steps.

[0069] It is worth mentioning that in step B, in addition to detecting the solder joints, the hot riveting point 1032 of the integrated busbar 100, the fuse, the QR code, and the contours of the auxiliary materials can also be detected. The detection content includes: whether the diameter of the hot riveting point 1032 meets the requirements, whether the fuse is broken, whether the QR code position is correct, and whether the auxiliary materials are missing; in step D, in addition to detecting the PIN pin, the connector contour and grayscale can also be detected. The detection content includes: whether the connector is damaged and whether there are foreign objects inside. In other words, in step B, multiple components on the upper surface of the integrated busbar 100 can be detected at the same time, and in step D, multiple components at the rear end of the integrated busbar 100 can be checked at the same time.

[0070] Specifically, in step C, the upper laser displacement sensor 51 and the lower laser displacement sensor 52 detect the thickness of the aluminum bar 103 by the triangulation method to determine whether the aluminum bar 103 in each area is over-installed, installed upside down, or missing. If the thickness of the aluminum bar 103 in an area is greater than the set value, it indicates that there are over-installed aluminum bars 103 in the area, resulting in overlapping of the aluminum bars 103. Since the thickness of the aluminum bar 103 at different positions is different, if the thickness of the aluminum bar 103 in an area is less than the set value but greater than zero, it indicates that the aluminum bar 103 in the area is installed upside down. If the thickness of the aluminum bar 103 in an area is zero, it indicates that the aluminum bar 103 in the area is missing.

[0071] Among them, the triangulation method belongs to the existing test method, which will not be described in detail here. Different from the prior art, the thickness detection mechanism 5 of the present invention performs detection in the process of synchronous movement with the surface visual detection mechanism 4.
