Description

[Detailed Description of the Invention] This invention relates to a speaker assembly adhesive applicator for bonding and assembling speaker field parts using an adhesive.

A conventional device of this type will be described with reference to FIG.

In the figure, a rotary table 1 is index-rotated by a human command or an automatic mechanical command, and is configured to rotate once with several commands. are arranged in a ring shape at equal intervals.

When assembling the bottom plate, magnet, and plate that constitute the speaker field part, first, while the rotary table 1 is stopped, place the bottom plate shown in FIG. 2 on the jig 2 at the position Pl. 3 is supplied and set manually.

In this state, the rotary table 1 is rotated by a certain angle, the jig in which the bottom plate 3 is set is indexed to the installation position P2 of the adhesive applicator 4, and the adhesive is applied onto the bottom plate 3 by the adhesive applicator 4. Apply.

Further, at the position P3 where the rotary table 1 is indexed and rotated, the magnet I-5 shown in FIG. 2 is manually placed on the bottom plate 3 coated with adhesive and overlapped.

In addition, the bottom plate 3 is overlapped with adhesive.
and the magnet 5 are transferred to the next position P4 with the indexing operation of the rotary table 1, and the adhesive applicator 6 at this position is moved to the next position P4.
The adhesive is supplied and coated onto the magnet 5 from the above.

Next, the rotary table 1 is indexed and the magnet 5 coated with the adhesive is transferred together with the bottom plate 3 to a position P5, and a plate 7 shown in FIG. 2 is placed on the adhesive coated surface of the magnet 5. are superimposed manually.

The bonded assembly of the bottom plate 3, magnet 5, and plate 7, which are superimposed and bonded to each other with adhesive in this way, is manually removed when the bottom plate 3, magnet 5, and plate 7 come to the ejection position with the next indexing operation of the rotary table 1. Rotary table 1
It is discharged outside.

However, in the conventional equipment described above, the bottom plate, magnet, and plate supply and removal of the bonded assembly are performed manually, resulting in poor work efficiency and limited production quantities. Become.

In addition, in adhesive lamination work, which is subject to time constraints such as open time and set time, as the supply and discharge are carried out by humans, the work intervals are irregular and the quality of the laminated assembly is unstable, resulting in poor adhesion. There were drawbacks such as:

This idea was made in order to eliminate the above-mentioned drawbacks of the conventional technology, and it automatically supplies components such as bottom plates, magnets, and plates to the adhesive bonding work position and discharges the bonded assembly. An object of the present invention is to provide an adhesive applicator for speaker assembly which is designed to stabilize quality and save labor.

An embodiment of this invention will be described below with reference to FIG.

In the figure, reference numeral 10 denotes a conveyance device that moves in the direction of the arrow, and its surface serves as a workbench.

Further, a bottom plate 3 is provided on the starting end side of the conveying device 10.
A bottom plate supply device 11 is disposed to supply the bottom plate onto the workbench of the conveyance device 10.
An adhesive application device 12 for applying adhesive to the bottom plate 3 is disposed on the conveying device 10 at a subsequent stage of the adhesive application device 1 .

Reference numeral 13 denotes a magnet supply device provided after the adhesive coating device 12, and the magnet 5 is placed and supplied onto the bottom plate 3 coated with the adhesive by this magnet supply device 13.

Further, reference numeral 14 denotes a magnet 5 provided on the rear side of the magnet supply device 13 and bonded to the bottom plate 3.
This is an adhesive applicator for applying an adhesive on the adhesive, and a plate supply device 15 is disposed downstream of this adhesive applicator 14 to overlap the bonded magnet 5 that has passed through the application process. There is.

Reference numeral 16 denotes a discharge device provided at the terminal end side of the conveyance device 10 for carrying out the bonded assembly.

Further, each of the supply devices 11, 13, 15, adhesive application devices 12, 14, and discharge device 16 are driven in synchronization with the conveyance device 10.

Next, the operation of the apparatus configured as described above will be explained.

The bottom plate 3 is stored and set in a fixed quantity supply device 11.

This bottom plate 3 is supplied and set to the mounting portion of the conveying device 10 by the supply devices 1, 1 under certain conditions in synchronization with the conveying device 10.

The set bottom plate 3 is transported in the direction of the arrow by the transport device, and then an adhesive composed of two liquids is sequentially applied onto the bottom plate 3 at a location where the adhesive application device 12 is provided.

The bottom plate coated with adhesive is again transported in the direction of the arrow by the transport device 10, and at the next work station, a magnet 5 is placed on the adhesive-coated surface of the bottom plate 3 in synchronization with the transport device 10. It is supplied and placed by a driven magnet supply device.

Then, the bottom plate 3 and the magnet 5 which are superimposed on each other are transported again by the driving of the transport device, and at the next work station, an adhesive consisting of two liquids is sequentially applied onto the magnet 5 by the adhesive application device 14.

The magnet 5 with adhesive applied is attached to the bottom plate 3
The plate 7 is transported again in the direction of the arrow by the transport device 10 in the pasted state, and at the next work station, the plate 7 is applied to the adhesive-coated surface of the magnet 5 by the plate supply device 15 driven in synchronization with the transport device 10. Place the supply.

Furthermore, the bottom plate 3, magnet 5, and plate 7 which are stacked on top of each other are again transported in the direction of the arrow by the driving of the transport device, and are automatically transported out of the transport device 10 by the discharge device 16 at the next work station.

The bonded assembly of the bottom plate, magnet, and plate that is carried out here has already been fixed with an adhesive and has sufficient adhesive strength.

Note that in the above embodiment, the conveying device 10 is linear, but
The same method can be applied to a device that is driven and conveyed in a circular shape.

As described above, according to this invention, the bottom plate, magnet, plate supply device, adhesive applicator,
Since the ejecting device is configured to be synchronized with the conveying device, there is no need for humans to supply and eject speaker field components, making it possible to save labor, as well as allowing the lamination assembly to operate continuously at a fixed repetition time. This has the effect of eliminating time loss, preventing poor adhesion of bonded assemblies, etc., and improving quality even in adhesive application operations that are subject to restrictions such as open time and set time.
