Automatic line drawing tool of neodymium iron boron permanent magnet

Abstract

An automatic line drawing tool of a neodymium iron boron permanent magnet is characterized by comprising a distance-adjustable transmission guide rail, a pressing wheel and a line drawing pen. The distance-adjustable transmission guide rail is used for containing and conveying the neodymium iron boron permanent magnet; the pressing wheel is used for flattening a neodymium iron boron permanent magnet strip; the line drawing pen is provided with a line drawing intensity adjusting mechanism. A motor is adopted to drive the automatic line drawing tool of the neodymium iron boron permanent magnet to automatically draw a line, labor is saved, and the efficiency is improved. The line drawing pen is inclined by a certain angle to be mounted, abrasion of the line drawing pen is reduced, the line drawing pen is pressed on the neodymium iron boron permanent magnet strip by means of the gravity of the pen and a line drawing intensity adjusting rod, and the height of the line drawing pen does not need to be repeatedly adjusted; the pressing wheel is arranged, so that the neodymium iron boron permanent magnet strip is flattened, and the line breaking condition is avoided. A compressed air nozzle is arranged, so that a drawn line can be rapidly blown dry, and the water seepage situation is avoided.

Description

technical field [0001] The invention relates to an automatic line drawing device and method for NdFeB permanent magnets, so as to automatically draw lines on the NdFeB permanent magnets according to customer requirements, and carry out marking of magnetic poles. Background technique [0002] The traditional line drawing method is manual operation. For example, Chinese patent 200810224854.2 discloses a manual line drawing tool for permanent magnets. A line drawing pen is used to vertically press the NdFeB permanent magnet, and the line drawing pen is fixed, and the product is pulled manually. Pass the product through a liner to leave a lined mark on the product. The line drawing pen is vertically installed and tightly pressed and fixed, the line drawing force is strong, the line drawing pen is easy to wear and tear, and the height of the line drawing pen needs to be adjusted repeatedly. The efficiency of this manual method is low, and there are the following problems: 1) Man...
