Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention transfers a work from a transfer path that transfers a work to another transfer path that is adjacent to the work path while reversing the transfer posture. The present invention relates to a transfer device, and more particularly, to a speaker transfer device that transfers a speaker between an assembly line and a drying line in a speaker manufacturing line.

<Prior art> In a speaker manufacturing line, a yoke, a magnet, and a frame with a plate are placed in order on an assembly line to assemble, and an adhesive is applied to each joint to bond each component, and the assembled work is dried. The work is transferred to a drying line running in the furnace to dry the adhesive to form the work piece into an integral structure. Conventionally, the work is transferred from the assembly line to the drying line, or from the drying line to the next step. The transfer to the transfer line was carried out by holding the magnet part integrated with the yoke of the speaker by the chuck of the transfer device and moving the speaker in parallel without changing the posture of the speaker.

<Problems to be solved> However, in the process, the adhesive force between the yoke and the magnet during transfer is relatively strong due to the influence of the weight of the magnet. Since the adhesive force between them has not elapsed since it was placed and the frame with a plate is lightweight, the pressing force is not sufficient and even if the frame rises when moving on the drying line, There is a problem that it affects the stability of the product because it cannot be corrected.

The present invention has been made in view of such a point, and provides a transfer device for reversing the speaker when transferring the speaker from the adjacent speaker assembly transfer path to the dry transfer path. The purpose is to
