Problems solved by technology

[0002] There are many designs for the magnetic circuit of the speaker. The magnetic circuit composed of several fan-shaped sheets in the radial direction has the advantages of uniform and stable magnetic field, good consistency, and small distortion. However, the assembly of this magnetic circuit is relatively difficult. The original assembly process is Paste pieces of magnetic steel on the magnetic bowl with glue by hand. Because the magnetic steel is already magnetic, the magnetic steel is easy to be adsorbed in one piece during assembly, and the magnetic steel absorbed in one piece is difficult to disassemble. The assembly and disassembly process There are problems such as easy pinching of fingers and difficulty in rework, and low production efficiency and pass rate

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0026] like figure 1 , 2 As shown, a magnetic steel assembly jig is specially designed for assembling magnetic bowls with radial magnetic circuits. A drive mechanism that drives the pressure rod 2 to move up and down. like Figure 4 As shown, the magnetic steel placement plate 8 is circular, with a through hole 26 in the middle, and the surface of the magnetic steel placement plate 8 is provided with several grooves 9 for placing the magnetic steel 27 around the through hole 26, The groove 9 is radial on the magnetic steel placement plate 8, and the surface of the magnetic steel placement plate 8 is divided into several sectors of equal size; one end of the groove 9 communicates with the through hole 26, and the other end communicates with the external space. The steel 27 can enter the groove 9 through the entrance connected to the outside, and t...

Abstract

A magnetic steel assembling fixture comprises a magnetic steel placing tray, a cover plate, a compression bar and a driving mechanism which drives the compressing bar to move up and down. A through hole is formed in middle of the magnetic steel placing tray. A plurality of grooves which are used for placing magnetic steel are formed around the through hole in the surface of the magnetic steel placing tray. One ends of the grooves are communicated with the through hole, and the other ends of the grooves are communicate with exterior space. The cover plate is arranged on the surface of the magnetic steel placing tray and a via hole is formed in the position of the through hole. The walking path of the compression bar is limited within the through hole. Containing space which is used for placing magnetic bowls is formed below the magnetic steel placing tray. The magnetic steel can be arranged on the grooves neatly. The magnetic steel which is arranged at the inner end can stretch out of the through hole. The compression mechanism is started and presses the compression bar downward, and the compression bar moves downward and penetrates through the through hole. The magnetic steel which is arranged at the inner end is taken away and pushed downward until the magnetic steel is pushed into the magnetic bowls which are below the magnetic steel placing tray, and therefore assembling of magnetic steel in the magnetic bowls is completed. The magnetic steel assembling fixture is high in assembling efficiency and safer in assembling process.

Description

technical field [0001] The invention relates to an assembly tool, in particular to an assembly tool for magnetic steel in a magnetic bowl with a radial magnetic circuit in a loudspeaker. Background technique [0002] There are many designs for the magnetic circuit of the speaker.
