Description

Technical Field

[0001] The utility model relates to the field of speaker production equipment, in particular to an automatic gluing and assembling device for a sound film of a speaker product. Background Art

[0002] A speaker is a transducer that converts electrical signals into sound signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest component in the audio equipment, but it is also the most important component for the sound effect. There are many types of speakers, and the prices vary greatly. Audio electrical energy vibrates the sound membrane through electromagnetic, piezoelectric or electrostatic effects and resonates (resonates) with the surrounding air to produce sound.

[0003] However, in the existing assembly and production of speakers, the sound membrane is generally installed by applying glue and then fixing it on the speaker bracket. However, the existing gluing device generally uses a three-axis mobile frame to install and fix it (its volume is large, the span is also large, so the corresponding equipment transportation cost is also high, and there is more coordination between the mechanisms), so the production efficiency is low, that is, the multi-axis coordination of a multi-axis manipulator is required to complete the gluing of the circular bracket, and its processing efficiency is slow. At the same time, the production cost of the multi-axis manipulator is also high. Utility Model Content

[0004] The main purpose of the utility model is to propose an automatic gluing and assembling device for a sound diaphragm of a speaker product, aiming to improve the existing sound diaphragm installation equipment so that it can improve the installation efficiency of the sound diaphragm and at the same time achieve higher gluing and installation accuracy.

[0005] To achieve the above purpose, the utility model proposes an automatic gluing and assembling device for a sound film of a speaker product, comprising:

[0006] A machine base, wherein the machine base is provided with a pivotally arranged turntable, the machine base is provided with a first driving device for driving the turntable to rotate, a jig is provided along the circumference of the upper wall of the turntable, the jig is used to place the sound film, and the jig is pivotally mounted on the turntable;

[0007] A second driving device, which is arranged on the machine base and located at the lower wall of the turntable. When the predetermined jig rotates to the top of the second driving device, the second driving device is connected to the jig and can drive it to rotate. The machine base is provided with a gluing position and an assembly position, and the jig can be rotated to a predetermined position.

[0008] The gluing device is arranged above the turntable and opposite to the second driving device. The gluing device is arranged on a two-axis moving frame. When the sound film is placed in the fixture, the two-axis moving frame can drive the gluing device to move to the gluing position of the sound film.

[0009] At the same time, the second driving device drives the sound film to rotate, and enables the glue coating device to coat the glue dot area of ​​the sound film with closed-loop glue;

[0010] The clamping device can drive the speaker bracket to move to the assembly position and install the speaker bracket on the sound membrane and apply a predetermined pressure to make the two fit each other.

[0011] In the actual design, circumferentially distributed jigs are arranged on the turntable, and predetermined speaker bracket loading positions, sound film loading positions, gluing positions, assembly positions and glue curing positions are arranged on the machine base, thereby realizing automatic loading, unloading and assembly. When the sound film is placed on the jig, the turntable drives the jig on which the sound film is placed to rotate and move to the gluing position. The gluing device moves down and contacts or maintains a gap with the gluing position of the sound film. Then the second driving device drives the jig to rotate and causes the gluing device to apply glue on the outer peripheral wall of the sound film. The turntable then drives the sound film coated with glue to move to the assembly position. The clamping device clamps the speaker bracket and moves it above the sound film to make the two bond to each other.

[0012] The automated equipment has a stable structure and high production efficiency, effectively replacing manual assembly, and has higher gluing and assembly accuracy, the accuracy of which is achieved by combining the jig, gluing equipment and clamping device.

[0013] That is, the multi-axis displacement of the gluing device is replaced by the self-rotation of the jig, which effectively improves the gluing efficiency of a single sound membrane and thus improves the assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
