Abstract
The invention discloses a kind of method improving piezoelectric buzzer weld intensity, belong to the making method of piezoelectric buzzer; Aim to provide a kind of method preventing electrode pin and piezoelectric ceramics piezo weld from loosening.Its method is: covered by the positive pole weld of piezoelectric buzzer with binding agent, then sends in baking oven and is heated to 75 ± 5 DEG C, heat preservation solidification 1 hour; Described binding agent is mixed by the weight ratio of 1:0.3:0.05:0.3 by bisphenol A epoxide resin, aliphatic amide, imidazoles, 501 glue.The present invention completely eliminates because product is frequently transported, vibrated and the phenomenon causing weld to loosen or come off, and reaches the anti-drop test requirements document of product completely; It is a kind of method preventing electrode pin and piezoelectric ceramics piezo weld from loosening.
Description
Technical field
The present invention relates to a kind of making method of piezoelectric buzzer, particularly relate to a kind of method improving piezoelectric buzzer weld intensity.
Background technology
Piezoelectric buzzer is a kind of sounding alarm device being widely used in household electrical appliance, is usually made up of the piezoelectric ceramics piezo be fixed in buzzing box, the electrode pin be welded in this piezoelectric ceramics buzzing.Because the silver layer on piezoelectric ceramics piezo surface is thinner, the weld stability of electrode pin and piezoelectric ceramics piezo is poor; Usually because product is frequently transported, vibrated and produce rosin joint, weld is caused to loosen or come off.
Summary of the invention
In order to overcome the defect existed in prior art, the present invention aims to provide a kind of method improving piezoelectric buzzer weld intensity.
To achieve these goals, technical scheme of the present invention is as follows: with the electrode welding Vertex cover of binding agent by piezoelectric buzzer, then sends in baking oven and is heated to 75 ± 5 DEG C, heat preservation solidification 1 hour; Described binding agent is mixed by the weight ratio of 1:0.3:0.05:0.3 by bisphenol A epoxide resin, aliphatic amide, imidazoles, 501 glue.
Compared with the prior art, the present invention is owing to have employed technique scheme, with binding agent weld is covered, solidification, effectively enhance the strength of joint of weld, completely eliminate because product is frequently transported, vibrated and the phenomenon that causes weld to loosen or come off.Test shows, after adopting technique scheme, piezoelectric buzzer freely falls for highly continuous three times from one meter, does not all occur that solder joint loosens phenomenon, reaches the anti-drop test requirements document of product completely.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described:
With the electrode welding Vertex cover of binding agent by piezoelectric buzzer, then send in baking oven and be heated to 75 ± 5 DEG C, heat preservation solidification 1 hour; Described binding agent is mixed by the weight ratio of 1:0.3:0.05:0.3 by bisphenol A epoxide resin, aliphatic amide, imidazoles, 501 glue.
In the above-described embodiments, bisphenol A epoxide resin mainly plays binding agent effect, and aliphatic amide and imidazoles play solidifying agent effect, and 501 glue play thinner effect.
Claims (1)
