An automatic laser marking device for a capacitor assembly line

Abstract

The invention discloses an automatic laser marking device for a capacitor assembly line, comprising: a workpiece placement area for placing multiple sets of strip-shaped capacitor workpieces through guide grooves; a processing preparation area for receiving workpiece placement areas through guide grooves Multiple sets of strip-shaped capacitor workpieces; marking processing area, used for positioning multiple sets of strip-shaped capacitor workpieces on the processing preparation area, and laser marking the strip-shaped capacitor workpieces after positioning; parts storage area, used to store lasers The marked strip-shaped capacitor workpiece; the transmission mechanism is used to drop the strip-shaped capacitor workpiece in the workpiece placement area into the parts storage area after passing through the processing preparation area and the marking processing area to complete a processing cycle. The invention realizes the automatic production of the assembly line through the automatic device, and only needs loading and unloading manually, which greatly improves the processing efficiency.

Description

technical field [0001] The invention belongs to the technical field of laser marking, and relates to an automatic laser marking device for a capacitor assembly line, in particular to a high-precision automatic laser marking device for a capacitor assembly line suitable for capacitors with small volumes and difficult to accurately locate. Background technique [0002] With the rapid development of my country's laser industry, laser marking technology has gradually become one of the largest application fields of laser processing. Its principle is to use high-energy-density laser to partially irradiate the workpiece, so that the surface material of the workpiece undergoes a chemical reaction of color change, thereby leaving a permanent mark. Compared with traditional marking methods such as acid corrosion, electric spark, and mechanical scribing, laser marking is a non-contact processing with small force / heat impact, wide material adaptability, flexible processing methods, and ...

Problems solved by technology

At present, there are two popular solutions; one is to design the mold according to the external dimensions of the workpiece, put the workpiece into the mold during processing, and process and produce by manual loading and unloading; but this method is difficult for processing efficiency. It is necessary to repeatedly replace different molds for marking different workpieces, which undoubtedly increases the difficulty and complexity of the worker's operation; the second is to add an image recognition module to the laser marking system, and use the method of image recognition to accurately identify the workpiece. However, although this method has significantly improved the marking accuracy and efficiency, the cost is too high, often the cost of an image recognition module even exceeds the value of the laser marking machine itself, so it is difficult to popularize
