Electromagnetic pen frequency adjustment device and method

Abstract

The invention discloses equipment and a method for regulating the frequency of an electromagnetic pen. The equipment for regulating the frequency of the electromagnetic pen comprises a bonding engine base (37), a fixed table (31) on the bonding engine base (37), a bonding nose (35), an electric displacement platform (34) and a controller (36), wherein the fixed table (31) is used for fixing an electromagnetic pen refill (32); the bonding nose (35) is arranged above the bonding engine base (37) and used for bonding a group of pads (202 and 203), needing short circuit, in the electromagnetic pen refill (32) positioned at a working area; the electric displacement platform (34) is used for moving the fixed table (31) so as to enable the group of pads (202 and 203), needing short circuit, in the electromagnetic pen refill (32) fixedly arranged on the fixed table (31) to be in a bonding working area; and the controller (36) is used for controlling the whole automatic value regulation process. The solder with a soldering bit is replaced by a bonding mode, the heat quantity is less, the capacitance fluctuation is small, and the value regulation result is more accurate; the equipment is automatically completed without manual intervention; the repeated value regulation is convenient; and the equipment and method are beneficial to realizing the automation of the whole electromagnetic pen production line in the future.
