Description

Laser spot welding lead wire correcting device Technical Field The utility model relates to the field of manufacturing of induction coils, in particular to a laser spot welding lead correction device. Background The inductor is used as one of three passive electronic basic elements in a circuit board of an electronic product, and is widely applied to the fields of consumer electronics, communication, industrial equipment, automobiles, new energy sources, internet of things and the like. Along with the rapid alternation of the Chinese communication technology and the large-scale construction of related industries such as the Internet of things, smart cities and the like, the market scale of the Chinese inductor rapidly develops. In order to meet the above application demands, the trend of the inductor is to be miniaturized, high-frequency and high-power. Under the trend of electronic products towards small, light and high performance, higher requirements are put on the reliability and integrated design of the inductor. The inductor mainly comprises a coil, a magnetic core and an electrode. The winding of the coil is critical to the quality of the inductor, and in the process of laser spot welding of the coil, the position of the opening of the coil lead cannot be unified, so that deviation can occur when the coil is matched with the lead frame, the machine adjustment is not facilitated, and the yield is low, as shown in fig. 1. Part of production lines depend on visual observation of operators and manual adjustment of lead positions, but manual intervention exists in that lead distance fluctuation range reaches +/-0.2 mm (spot welding allowable tolerance is +/-0.05 mm) due to correction force difference of different operators, and operation errors are easily caused by fatigue because manual intervention is needed for more than 200 times per shift. Disclosure of utility model Therefore, the utility model aims to provide the laser spot welding lead correction device which can be specially used for correcting leads and improve the qualification rate of products. In order to achieve the above purpose, the present utility model provides the following technical solutions: A laser spot welding lead correction device comprising: the base is internally provided with a guide rail extending in the vertical direction, and an upper sliding seat and a lower sliding seat are symmetrically and slidingly connected on the guide rail; the driving unit comprises two symmetrically arranged air cylinders which are respectively arranged at two ends of the base, and the end parts of piston rods of the air cylinders are connected with corresponding sliding seats; The end face of the bearing plate is provided with station grooves distributed in an array manner, an opening penetrating through the plate body and a limit groove communicating the station grooves with the opening; A tool holder assembly, comprising: The bottom of the upper tool apron is provided with a plurality of correction blocks, and the tail ends of the correction blocks are wedge-shaped tips; A lower tool apron fixedly connected with the lower slide seat; The bearing plate is positioned between the upper cutter seat and the lower cutter seat, and the wedge-shaped tip movement path of the correction block corresponds to the position of the opening of the bearing plate. The utility model further provides that the wedge-shaped tip of the correction block is of an equilateral triangle structure.
