[0002] The snail horn is a normal horn with a snail-shaped sound-assisting cavity. It improves the sound quality and increases the volume. The snail horn is a pair of car horns. They are called snail horns because they look like snails. To distinguish them from basin-type horns, they are actually called "treble and bass horns". One of the two horns is treble and the other is bass. Due to its structure, the snail horn can make the sound louder and farther with the same power through the vibration of the resonance box. At the same time, it is relatively energy-saving, and the sound sounds majestic, loud and full. Compared with traditional horns, the sound is fuller and the life is longer.

[0003] During the assembly process of the snail horn, the diaphragm, the core and the gasket need to be assembled into a semi-finished diaphragm, and then assembled with the semi-finished base, and riveted together by a tight ring; in the existing assembly process, the various components are assembled together manually, and then the various components are riveted together by an external riveting mechanism, and the overall degree of automation is low; not only a large amount of labor costs are required, but also the assembly efficiency is low. Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the invention

Finally, the qualified products are unloaded into the external conveying device through the diaphragm unloading device 90d, and the unqualified products are unloaded into the external waste box 44d.

[0062] At this time, the qualified products are transported to the diaphragm feeding device 30e of the snail horn detection device e through the external conveying device; when the snail horn detection device e is working, the annular conveyor line 11e is used to convey the jig, wherein the tight ring feeding device 20e first feeds the tight ring into the corresponding jig, and then the annular conveyor line 11e drives it to move backward to the diaphragm feeding device 30e, and completes the flipping and feeding process of the diaphragm semi-finished product through the diaphragm feeding device 30e; then the annular conveyor line 11e drives it to continue to transport it backward to the paper pad feeding device 40e, and feeds the paper pad to the diaphragm semi-finished product through the paper pad feeding head 45e The semi-finished chassis delivered by the external conveying device is then turned over and loaded onto the paper pad by the chassis loading device 50e along with the conveying of the annular conveying line 11e; thereafter, the two riveting assemblies 63e in the tight ring riveting device 60e perform two riveting processes in sequence, so that the tight ring is deformed inwardly by 90°, thereby assembling the various components together; after the assembly is completed, the fine adjustment device 70e adjusts the screw angle, and the breath detection device detects the deformation of the diaphragm, and finally the qualified products are unloaded by the unloading device 90e, and the unqualified products can slide out through the chute 92e.

[0063] The design focus of the present invention is that by providing a snail horn diaphragm assembly device and a snail horn riveting detection device, the automatic assembly process of the diaphragm semi-finished product is first completed by the snail horn diaphragm assembly device, and then the diaphragm semi-finished product is riveted and assembled with the assembled chassis semi-finished product through the snail horn riveting detection equipment; the overall automation level is higher, only less manual participation is required, the labor cost is greatly reduced, and the automated processing method makes the overall processing efficiency higher.

[0064] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
