超聲波塑膠焊接不牢固怎么處理?

Source of the article:Huacheng ultrasound | Author:Huacheng ultrasound | Issuing Time:2020-09-16

超聲波塑膠焊接不牢固,如是舊工裝,先用產(chǎn)品貼在焊頭上,觀察焊接不牢處的產(chǎn)品與焊頭之間是否有過大的間隙,判斷是否有磨損;如是新工裝,用焊頭掃描,觀察其頻率、功率及曲線,判斷是否有磨損;可先用卡尺卡對(duì)焊接后的產(chǎn)品尺寸,根據(jù)不同數(shù)據(jù)進(jìn)行調(diào)試:

 

1.產(chǎn)品整體高度過大。請(qǐng)修改焊接參數(shù)以提高焊接深度。修正后,若缺陷可排除,請(qǐng)觀察其它部位是否有滲漏;

 

2.焊接不牢處尺寸偏大,其他位置尺寸OK,請(qǐng)調(diào)節(jié)水平板,將對(duì)應(yīng)位置抬高,如果調(diào)節(jié)水平板對(duì)其他位置影響較大,可以在焊接不牢處的工裝上貼薄錫紙;

 

3.調(diào)整焊頭尺寸,請(qǐng)調(diào)整以下參數(shù):增大振幅,減小壓力,減慢焊頭下降速度,如果能消除不良,請(qǐng)確認(rèn)其他位置是否溢出;

 

以上步驟完成后,超聲波塑膠焊接仍然不牢固,或者焊接尺寸太小,請(qǐng)咨詢深圳華鋮超聲。
