[0002] With the continuous development of new energy vehicles, more and more functional requirements are integrated into the automotive control system chip. The miniaturization and lightness of chips has become a development trend, but with it comes a substantial increase in chip heat dissipation. The water cooling plate is designed to solve the chip heat dissipation needs. In order to ensure the heat dissipation effect of the chip circuit board, a large number of heat dissipation bases are welded on the water cooling plate to correspond to the chip board and fit together with thermal conductive adhesive. These heat dissipation bases need to be machined to ensure high-precision installation dimension requirements, and the processing dimensions need to be 100% inspected. The inspection dimensions involve surface contour, flatness, and position (a total of 150 inspection dimensions). The two ends of the water cooling plate are usually installed with vertically set current collectors, and the dimensional accuracy requirements are very high.

[0003] The current practice is to use a three-dimensional coordinate measuring machine to detect the dimensions of all the heat dissipation bases of the product. The three-dimensional coordinate measuring machine is a precision measuring instrument for three-dimensional dimensions, mainly used to detect the size, shape and relative position of parts. It has the following shortcomings: 1. Three-dimensional coordinate measuring machine detection requires a lot of time, and it takes about 80 minutes to detect a product; 2.

[0019] The working principle of a 2D and 3D detection device for a water-cooled plate 3 of the present scheme is as follows: first, the water-cooled plate 3 is placed on the product pad 16, and then the lifting cylinder 171 of the pressing component 17 is actuated, and the lifting cylinder 171 drives the Z-shaped connecting frame 172 and the pressing plate 173 to descend until the pressing plate 173 is pressed onto the water-cooled plate 3 to fix the water-cooled plate 3. The function of the first linear module 12 is to adjust the position of the entire fixed plate 13 and the product pad 16 according to the size of the water-cooled plate 3, so as to facilitate the image detection mechanism 2 to be able to fully detect. A light hole is provided on the fixed plate 13, and the product pad 16 is provided on the light hole. During detection, the 2D image detection component 23 of the image detection mechanism 2 first scans the QR code on the water-cooled plate 3 through the upper CCD232 and the lower CCD233 to identify the product.

The number of scans can be several times. The four 3D cameras 244 arranged on the 3D detection bracket 241 are arranged around the through hole 242, so that the top surface, bottom surface and two side surfaces of the water-cooled plate 3 can be scanned and recorded, thereby recording the surface contour, flatness, position and other information of the water-cooled plate 3.

During adjustment, the side push cylinder 181 drives a plurality of L-shaped push blocks 183 through the push plate 182 to push the product, thereby ensuring the position parallelism of the water cooling plate 3 and improving the detection accuracy.
