Description

Wire guide plate feeding mechanism

Technical Field

The invention relates to the technical field of manufacturing of chip inductors, in particular to a feeding mechanism of a wire guide plate.

Background

The surface mounted inductor is an electromagnetic induction element formed by winding an insulated wire, and is mainly applied to the technical field of production and manufacturing of notebook computers, automobile electronic accessories, Bluetooth earphones, sound equipment and the like. The forming process of the chip inductor is roughly as follows: firstly, the spring coil is welded and fixed on the wire guide plate, then the cutting operation is carried out, and then the surface mounted inductor is processed.

In the prior art, the procedures of feeding, welding, wire cutting and the like of the spring coil relative to the wire guide plate are usually realized in a manual operation mode, the operation is time-consuming and labor-consuming, the production efficiency is low, and a large amount of metal dust is inevitably generated in the welding process to endanger the physical and mental health of workers. For this reason, the company has recently developed an automatic welding device for a wire guide plate, which mainly comprises a base station, a feeding mechanism, an automatic receiving mechanism, a wire guide plate loading mechanism, a wire guide plate welding mechanism, and a wire guide plate cutting mechanism, wherein the automatic receiving mechanism is vertically fixed on the upper surface of the base station, and is opposite to the spring machine, and is used for receiving the formed spring coil and then transferring the spring coil to the wire guide plate loading mechanism. It should be noted that, before the above-mentioned transfer process is performed, the wire guide plate is transferred from the placing tool to the wire guide plate placing jig by the feeding mechanism, and then the wire guide plate placing jig is placed in place relative to the wire guide plate loading mechanism. The spring coil is placed in the wire guide plate. Then, the wire guide plate and the spring coil are moved to a welding station under the action of the wire guide plate loading mechanism, and the wire guide plate and the spring coil are welded and fixed by means of welding of the wire guide plate; and then, the wire guide plate loading mechanism moves the welded wire guide plate to a wire cutting station, and the wire guide plate wire cutting mechanism is used for completing the separation of the preformed product of the chip inductor and the wire guide plate. Although the automatic welding equipment for the wire guide plate effectively reduces the investment of production working hours and improves the production efficiency and the forming quality of the preformed product of the chip inductor in multiples, the automatic welding equipment for the wire guide plate has the following defects: generally, the feeding mechanism usually uses a robot to grasp and transfer the wire guide plate, however, the wire guide plate is less rigid due to its thin thickness. Therefore, in consideration of preventing the wire guide plate from deforming, a plurality of grabbing points are required to be uniformly distributed around the periphery of the wire guide plate, so that the design difficulty of a manipulator is increased, the acquisition cost is high, and the space integral design and layout of the automatic welding equipment for the wire guide plate are not facilitated; in addition, when adopting the manipulator to snatch the conductor board, can increase the structural design difficulty that the frock was place to the conductor board to a certain extent, therefore, the technical staff that await urgent need solves above-mentioned problem.
