Specifically, as shown in fig. 14 and fig. 15, the present embodiment further includes a blanking sensing mechanism 8 located at the rear end of the assembly line 41 on the basis of the above embodiments, the blanking sensing mechanism 8 includes a workbench 81, two guide rails 82 arranged in parallel on the workbench 81, and two sliding rods 83 arranged in parallel with the guide rails 82 and located outside the two guide rails 82; the two sliding rods 83 are fixed on the working table 81 through a plurality of fixing seats 84.
The working table 81 in this embodiment provides a plane for mounting other components, the guide rail 82 is used for bearing a jig, when the jig slides on the guide rail 82, the jig rubs against the sliding rods 83 on both sides, and finally, the jig slowly stops depending on the friction force. When the jig is transported again and cannot be transported forward, the jig detection sensor 46 detects that the jig is not moved, and the transportation of the jig can be stopped, so that the jig can be cleaned manually. The support that the workstation 81 below in this embodiment formed for the stainless steel square tube welding plays the effect of support, and foot cup and truckle are still installed to the bottom, the convenient removal.
According to the automatic laser marking tracing device, the automatic operation of product marking is realized by adopting the assembly line operation, the labor intensity of operators is reduced, the first jig positioning component and the jig forward and backward detection component can detect and support the reversed jig, so that the operators can adjust the automatic laser marking tracing device in time, and the consistent specification of the marked products is ensured; the second jig positioning component is matched with the laser marking mechanism, so that accurate marking operation of the product is realized; the cooperation of third tool locating component and sweep a yard mechanism has realized the scanning of product sign, guarantees the quality to reach standard of product, has also realized tracing to the source of product.
The present invention has been further described with reference to the specific embodiments, but it should be understood that the detailed description should not be construed as limiting the spirit and scope of the present invention, and various modifications made to the above embodiments by those skilled in the art after reading the present specification are within the scope of the present invention.
