Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a magnetic circuit section transfer device for a speaker manufacturing line.

Generally, the magnetic circuit section includes a yoke, a pole, a magnet section 4A, a magnet, and a plate. These magnetic circuit components are stacked in order on a yoke in which poles are connected together and connected to each other by adhesive or the like. During this assembly process, the pole should be fitted with a gap gauge or I to maintain the space around it.
E. It will be worn. In the present invention, the term "magnetic circuit section" refers not only to the magnetic circuit parts described in (-) above, but also to the pole on which one gear budane is attached and the line on which four large gear amplifier gauges are attached. It is used in the sense of including the magnetic circuit part's crystal phase, which is treated as a group.
・I'll do it. Therefore, the present invention is an assembly of all magnetic circuit components from a pole to which a gap gauge is directly attached. Transfer of goods between partial lines within an assembly line, for example, from a plate assembly line *l
Used for transferring items from the 1st and 11th lines It is widely applied to items transferred from the 1st and 11th lines to outside the assembly line.

Conventional Examples and Their Disadvantages Conventionally, components of a magnetic circuit section of a speaker manufacturing line are bonded to each other using an adhesive. The adhesive used here is an inexpensive one that takes a relatively long drying time to be suitable for mass production through assembly line operations, and in order to shorten the drying time, the adhesive was applied and stacked on top of each other. The magnetic circuit section is placed in a drying oven. In this case, each part of the magnetic circuit section has not yet been effectively glued, so it is impossible to lift and transfer the magnetic circuit section from the pallet of the magnetic circuit assembly line to the conveyor of the drying line. It was said that it was bad. Therefore, by pushing the magnetic circuit part from the side, the pallet of the magnetic circuit part stand line is moved from the pallet of the drying line.

That is, as a conventional magnetic circuit (1b) transfer device for a speaker manufacturing line, there is one shown in FIG. This is equipped with a spanning plate 33 between the plate group E1 line 31 and the drying line; The drying line 32 can be pushed to the second side of the conveyor 36.

However, in this conventional system, the pallet 34 or 36
There is a disadvantage that the magnetic circuit section 35 may get stuck or vibrate at the joint 11 between the front plate 33 and the connecting plate 33, resulting in misalignment of the magnetic components and a decrease in adhesive strength. However, if there is a misalignment of the magnet part H that affects the magnetic flux distribution, there is a drawback that the quality of the product may become uneven, such as distortion of the sound of the speaker. In addition, there is also a drawback that the bottom surface of the magnetic circuit section 35 is scratched.

In order to eliminate these drawbacks, an attempt was made to transfer the magnetic circuit parts in their entire pallets from the independent magnetic circuit part line to the drying line. There is a drawback of having to equip a large number of pallets that are loaded onto the conveyor of the line.

(Objective of the invention 2) The present invention aims to prevent the magnetic circuit from being moved during the transfer of the magnetic circuit, without causing any misalignment of the magnetic circuit components, and preventing the magnetic circuit from being scratched (=1). The white of the eyes.

<Structure and Effects of the Invention> In order to achieve two objects, the present invention attracts the magnetic circuit section at the upper attraction position of the pick-up stage, and removes the magnetic circuit at the attraction release position on the second side of the receiving stage.

After moving to restage 11, adsorption 11
The present invention is characterized in that a transfer device i'i for lowering the distal position 11 is provided.

With this configuration, the magnetic circuit 2H1 is attracted to the chuck device at the pick-up stage, lifted from the spot, and then transferred to the receiving stay 7". and then released from the chuck device. In this way, the magnetic circuit part is not moved so as to rub against the pallet, spanning board, or their navy blue; There is no misalignment of magnetic circuit components.

As a result, the assembly precision of the magnetic circuit section can be improved, the size can be reduced, and the reliability of product performance can be improved. Also,
There are scratches or other scratches on the magnetic circuit. Furthermore, since pallets are not sent into the drying line, there is no need to increase the number of pallets, and the process can be carried out at low cost.
