Abstract
Description
Technical Field
[0001] The utility model relates to the field of speaker production equipment, in particular to a plasma glue coating turntable assembly machine for speakers. Background Art
[0002] A speaker is a transducer device that converts electrical signals into acoustic signals. Its performance significantly impacts sound quality. While the speaker is the weakest component in audio equipment, it is also the most crucial component for optimal sound quality. Speakers come in many varieties, and their prices vary widely. Audio electrical energy, through electromagnetic, piezoelectric, or electrostatic effects, causes the diaphragm to vibrate, resonating with the surrounding air and producing sound.
[0003] However, in the existing speaker assembly production, the paper cone needs to be fixed to the bracket. However, in the existing production, it is found that directly applying glue has a relatively smooth surface. Therefore, after applying glue, the adhesion effect of the glue to the bracket is poor (the existing ones are generally rough-molded, which is more difficult to process or the mold is more complicated). Therefore, after the paper cone is fixed with glue, it often has problems such as partial splitting or loose adhesion.
[0004] At the same time, the existing paper basin is generally fixed with a snap buckle, and the current installation is generally achieved by pressing, but the problem of rebound and falling off may occur when the opening is released, affecting production efficiency. Utility Model Content
[0005] The main purpose of this utility model is to propose a plasma glue coating turntable assembly machine for speakers, which aims to improve the existing paper cone assembly equipment so that the glue can be firmly adhered to the bracket. The paper cone can be stably installed and the combination is stable, which effectively improves the production efficiency and realizes the automated or semi-automated production of speakers.
[0006] To achieve the above purpose, the utility model proposes a plasma glue coating turntable assembly machine for speakers, comprising:
[0007] A machine base, wherein the machine base is provided with a pivotally mounted turntable, the turntable is provided with jigs spaced apart along its circumference, the jigs being pivotally mounted on the turntable, and the jigs being used to place the speaker bracket;
[0008] The outer periphery of the machine base is provided with a loading position, a plasma processing position, a gluing position, a pressing position and a unloading position in sequence;
[0009] A plasma processing device, wherein a first rotating device is provided adjacent to the plasma processing device. When the jig rotates to the plasma processing position, the first rotating device is connected to the jig and can drive the jig to rotate. At the same time, the plasma processing device sprays plasma particles circumferentially on the speaker bracket.
[0010] A gluing device is provided adjacent to the gluing device. When the speaker bracket is processed by the plasma processing device, the speaker bracket is moved to the gluing position under the rotation of the turntable. At this time, the second rotating device is connected to the jig and can drive the jig to rotate. At the same time, the gluing device applies glue to the circumference of the speaker bracket;
[0011] A pressing device, when the speaker bracket is coated with glue by the gluing device, the jig rotates to the pressing position, and the pressing device buckles the paper cone to the speaker bracket and pre-presses it for a predetermined time;
[0012] The unloading device can move the speaker bracket equipped with the paper cone and unload the material when the turntable drives the jig to rotate to the unloading position.
[0013] In actual processing, the cooperation of the first rotating device and the second rotating device enables the speaker bracket to be oriented when being processed by the plasma processing device and the gluing device, making plasma spraying and gluing faster and more convenient;
[0014] The use of a plasma processing device can form a layer of ion particles on the speaker bracket, which makes the glue more adherent without damaging the structure of the bracket, making the glue bonding more stable; the pressing device pre-presses for a predetermined time to achieve downward pressure maintenance, ensuring the stable installation of the paper cone.
