[Prior Art] The image measuring machine breaks the grid of using the manual measurement of each dimension of the product and its shape and bit tolerance to determine whether the product is qualified. The image measuring machine uses the backlight module to project the product, and then uses the lens f of the image measuring machine to judge the yield of the product shape. The traditional manual judgment is undoubtedly greatly improving the work efficiency and reducing the human error. However, the backlight module of the conventional image measuring machine cannot move in synchronization with the lens. In order to meet the needs of the lens at various positions, the backlight module has to be arranged as a strip light source that runs through opposite ends of the workbench. When the lens of the image measuring machine is moved to another place, the light source that does not correspond to the lens cannot be turned off, resulting in a waste of a large amount of energy. At the same time, the operator has a long-term view of the light source that does not correspond to the lens, which impairs the visual acuity and causes a certain human error.

At this time, the connecting member 36 is moved left and right to drive the backlight module 10 to move left and right, so that the backlight module 10 is adjusted to be on the same vertical line as the lens mounted on the beam 24. When the backlight module 10 is in the same vertical line as the lens, the screw 94 is tightened to lock the cable 100 to the positioning block 90. Turning on the power causes the backlight module 10 to emit light. When the tester operates the drive mechanism to move the lens to the right as needed, the drive mechanism pulls and the first and second fixing plates 240, 242 and the ropes 100 connected thereto move to the right. Therefore, the rope 100 connected to the first fixing plate 240 bypasses the first pulley 502 of the fixing member 50 and the third pulley 530 of the fixing member 53, and has a pulling force to the right of the positioning block 90 and the connecting member 36, and drives the positioning block. 90 and connector 36 move to the right. The rope 100 connected to the second fixing plate 242 also moves to the right. At this time, the backlight module 10 fixed to the connecting member 36 moves along with the connecting body 36 to follow the lens, thereby achieving the effect of synchronous movement with the lens. At this time, one end of the link 14 connected to the connecting member 36 moves to the right with the q-connecting member 36, and the carrier 14 is moved to the supporting portion 162 of the bracket 16 at the position of the top end of the guide rail 324 of the slide rail 32. When the tester operates the drive mechanism to move the lens to the left as needed, the motion is similar to the movement of the lens to the right, but the direction is different. In other embodiments of the interlocking mechanism of the present invention, the positioning block 90 may not be required, and a through hole for passing the rope 100 may be disposed directly on one side of the through groove 360 of the connecting member 36, and a top portion of the connecting member 36 is provided. The fixing holes intersecting the through holes pass through the fixing holes to lock the rope 100 to the connecting member 36. 13 200944744 In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations in the spirit of the present invention will be apparent to those skilled in the art. All should be covered by the following patent application.
