On the long hole 15, there are multiple product pads 16 for supporting the water-cooled plate 3. At the bottom of the fixing plate 13, there are also multiple pressing components 17. Each pressing component 17 includes a lifting cylinder 171. The lifting cylinder 171 is connected with a Z-shaped connecting frame 172 passing through the long hole 15. At the top of the Z-shaped connecting frame 172, there is a pressing plate 173 capable of pressing on the water-cooled plate 3. The image inspection mechanism 2 includes a marble platform 21, a second linear module 22 arranged on the marble platform 21, and a 2D image inspection component 23 and a 3D scanning component 24 arranged on the second linear module 22.
