The height position of the first drag chain plate 18 on the module base plate 11 is higher than that of the lead screw nut connecting piece 14 and is spaced from the lead screw nut connecting piece 14. One end of the dust-free drag chain 32 is fixed on the first drag chain plate 18. A second drag chain plate 19 is fixedly arranged on the top of the lead screw nut connecting piece 14. The height position of the second drag chain plate 19 on the module base plate 11 is lower than that of the first drag chain plate 18.

When the slider 171 slides to the end position of either end of the two ends of the linear guide 17, that is, when the connecting plate 15 and the light source box 21 move to the left limit or the right limit position, the groove sensor 173 senses the induction piece 172, feeds an electrical signal to the PLC, and the PLC controls the background to alarm and display the position information, and controls the motor 131 to pause working to prevent the lead screw 12 from continuing to rotate, resulting in damage to related components such as the lead screw nut connector 14, the connecting plate 15, and the light source box 21.

[0042] In the multi-light source switching and adjusting mechanism of the present utility model, a variety of light sources 22 are integrated on the light source box 21. The motor 131 is used to drive the lead screw 12 to rotate, driving the lead screw nut connector 14 to reciprocate on the lead screw 12, thereby driving the connecting plate 15 and the light source box 21 to reciprocate, realizing the position adjustment of the light source box 21 and the variety of light sources 22 arranged thereon; the variety of light sources 22 are powered by a light source controller, and the lighting states of the variety of light sources 22 are respectively controlled, so as to be able to realize the switching of the variety of light sources 22, meet different lighting requirements, and thus improve the detection ability and detection efficiency of the equipment.

[0043] The above embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to include these changes and modifications.
