Problems solved by technology

[0003] In the traditional process, the NdFeB magnets are first pasted with iron sheets before being magnetized, then assembled in the speaker, and then magnetized. However, NdFeB magnets are strong magnets, and they are often installed in the speaker iron bowl In the case of unsaturated magnetization, in order to ensure the magnetization saturation of the magnetic sheet, a high-power magnetizer is required to complete the magnetization, and the cost is relatively high. However, for the magnetized NdFeB magnetic sheet, because it is magnetic, it cannot be pasted. The process has to be carried out piece by piece, seriously affecting production efficiency

specific Embodiment

[0046] The diameter of the magnetic sheet 6 is 14 mm, the height is 4 mm, the diameter of the iron sheet is 14 mm, and the height is 2 mm. The magnetic sheet plate 2 is designed, and the distance between every two magnetic sheet grooves 22 is designed at 12-13 mm, which can ensure that the magnetic sheet 6 is scraped into When in the magnetic sheet groove 22, can not attract each other because the distance is too close, and the magnetic sheet plate 2 is compounded with an iron plate-24 simultaneously, and the magnetic sheet 6 can be firmly sucked in the magnetic sheet groove 22.

[0047] Place the magnetic plate 2 on the workbench 1, pre-position the magnetic plate 2 through the limit post 11, and insert the limit post 2 12 into the limit hole 21 of the magnetic plate to realize the positioning of the magnetic plate 2. Precise positioning ensures that the ejector pin 13 can be aligned and passes through the ejector pin hole 23 of the magnetic plate. The adhesive plate 3 is rev...

Abstract

The invention discloses a magnetic bonding process for a small neodymium iron boron belt. The magnetized neodymium-iron-boron magnetic sheet is scraped into the magnetic sheet plate by the magnetic rod; the magnetic sheet plate on which the magnetic sheets are scraped is placed on an operating platform; the bonding plate is reversely pressed on the magnetic sheet plate; pressing bonding plate by hands, the magnetic sheet is transferred into the bonding plate from the magnetic sheet plate through the workbench; gluing the magnetic sheet and adhering the iron sheet to the glued surface of the magnetic sheet; when the magnetic sheet pasting device is used, the bonding plate is placed on the workbench, the sheet taking isolation plate and the adsorption plate are pressed on the bonding plate at a time, the magnetic sheet subjected to pasting work is transferred by the bonding plate through the sheet taking isolation plate and adsorbed to the adsorption plate, and the adsorption plate is placed on the material frame and transported to a production line to be assembled and used.

Description

technical field [0001] The invention relates to the technical field of loudspeaker production, in particular to a small-sized NdFeB tape magnetic bonding process. Background technique [0002] The loudspeaker is also called "horn". It is a very commonly used electro-acoustic transducer device, which can be seen in sound-emitting electronic and electrical equipment. The speaker works through the magnetic effect of the current, and the sound is converted into currents of different sizes. The current is forced to hit the paper cone in the magnetic field, and the sound is emitted. For this reason, a NdFeB magnetic sheet needs to be assembled inside during the loudspeaker production process. [0003] In the traditional process, the NdFeB magnetic sheet is first pasted with an iron sheet before being magnetized, then assembled in the speaker, and then magnetized. In the case of unsaturated magnetization, in order to ensure the magnetization saturation of the magnetic sheet, a h...
