Embodiment 1

[0033] Embodiment 1: A magnetic steel mounting device for a loudspeaker, such as figure 1 As shown, it includes an installation platform 1, on which a fixed cylinder base 2 and a magnetic steel push mechanism 3 are arranged side by side, and a cylindrical magnetizing sleeve 4 is vertically screwed on the upper end of the fixed cylinder base to charge the cylinder. The magnetic sleeve is preferably made of aluminum alloy so as to be easily made by extrusion. like figure 2As shown, the magnetizing sleeve is provided with sealing caps 41 at both ends, and the lower end of the magnetizing sleeve is an external thread, and the upper end is an internal thread, and the corresponding lower end cap is an internal thread, and the upper end cap is an external thread. In this way, on the one hand, the cover and the magnetizing sleeve form a threaded connection; on the other hand, by setting the corresponding internal thread on the fixed sleeve, when the cover at the lower end of the mag...

Embodiment 2

[0038] Embodiment 2: A magnetic steel mounting device for a loudspeaker, such as Figure 4 , Figure 5 As shown, it also includes an installation platform 1, a fixed cylinder seat 2 and a magnetic steel pushing mechanism 3 arranged side by side on the installation platform. Unlike embodiment 1, there is no need to set a magnetic steel placement platform on the fixed cylinder base. In order to realize the automatic installation of the magnetic steel, we can set the magnetic steel installation mechanism 6 on the side away from the magnetic steel pushing mechanism of the fixed cylinder seat. The magnetic steel installation mechanism includes a delivery bracket 61 fixed on the installation table, and a The vertical conveying cylinder 62 corresponds to one of the loudspeaker skeleton positioning seats 51 of the conveying track 5 located at the lower part of the conveying bracket. The downward piston rod 621 of the conveying cylinder is made of non-ferromagnetic materials such as ...

Embodiment 3

[0042] Embodiment 3: A magnetic steel installation method for a loudspeaker, specifically comprising the following steps:

[0043] a. First put the magnetic steel blanks into a magnetizing sleeve made of non-ferromagnetic material. The magnetizing sleeve has a cover screwed to its open end, and then screw the magnetizing sleeve on Put the cover into the magnetizing machine to magnetize the magnet steel blank, so that the magnet steel blank in the magnetization sleeve becomes magnet steel. At this time, the magnetic steel in the magnetizing sleeve forms a magnetic steel string with the same polarity and is attracted to each other, and the magnetizing sleeve constitutes a storage container for the magnetic steel. Since the cross-section of the magnetic steel is usually circular, the magnetizing sleeve preferably adopts a matching cylindrical barrel structure. When the cross-section of the magnetic steel is in a rectangular shape, the inner cavity of the magnetizing sleeve The c...

Abstract

The invention discloses a device and method for installation of magnetic steel of a loudspeaker. The device for installation of the magnetic steel of the loudspeaker comprises an installation platform face. A fixing cylinder base and a magnetic steel pushing mechanism are arranged on the installation platform face side by side, the upper end of the fixing cylinder base is connected with a vertical magnetizing sleeve in a threaded mode, the magnetic steel pushing mechanism comprises a pushing rod capable of transversely moving and a power source driving the pushing rod to move forwards and backwards, the pushing rod is provided with a starting position and a stopping position after forward-movement is conducted, the side, corresponding to the pushing rod, of the fixing cylinder base is provided with a pushing rod hole matched with the pushing rod, the other side of the fixing cylinder base is provided with a magnetic steel outlet opposite to the pushing rod hole, the magnetizing sleeve and the pushing rod are both made of a non-magnet material, and a magnetic steel blank is placed in the magnetizing sleeve for overall magnetization so that a magnetic steel string with the same magnetic pole direction can be obtained and the magnetic steel can be pushed out by the pushing rod one by one, and therefore automatic installation of the magnetic steel can be achieved. According to the device and method for installation of the magnetic steel of the loudspeaker, the production efficiency is high, automatic production is easy to achieve, and reverse installation of the magnetic steel can be avoided in the process of installation.

Description

technical field [0001] The invention relates to a loudspeaker manufacturing technology, in particular to a method for installing magnetic steel on the skeleton of the loudspeaker. Background technique [0002] When assembling the loudspeaker, the magnetic steel needs to be placed in the magnetic bowl of the loudspeaker skeleton. The shape of the magnetic steel is mostly a cylinder. For example, "a kind of magnetic steel for loudspeaker" disclosed in the Chinese patent literature, the announcement number is CN202713553U, The magnetic steel body of the magnetic steel is cylindrical as a whole, one end of the magnetic steel body is provided with a tapered surface, and the inside of the magnetic steel body is provided with a truncated circular cavity. The magnet steel billet has strong magnetism after magnetization, so it will be attracted to each other messily. Therefore, when installing the magnet steel, the operator needs to separate the magnet steel first, and then distingui...
