AI Technical Summary

Technical Problem

The printing on existing surface-mount aluminum electrolytic capacitors is prone to cracking after the ink printing process, and the lack of a product alignment device in the ink printing equipment leads to blurry printing.

Method used

A printing device including a preheating device and a product straightening device was designed. The product is preheated by the preheating pipe to keep the temperature of the printing part between 250℃ and 300℃. The product straightening clamp is used to keep the product stable when the machine vibrates, preventing the printing from cracking and blurring.

Benefits of technology

It effectively prevents the printed text from cracking during reflow soldering, ensuring the clarity and stability of the printed text and improving product quality.

Abstract

一种贴片式铝电解电容器的奈印装置，包括产品输送装置、奈印组件和预热装置；奈印组件包括奈印模、油墨槽和奈印运动组件；奈印模连接在奈印运动组件上并且在奈印运动组件的作用下，奈印模在产品输送装置上的产品和油墨槽之间往复运动；预热装置包括预热管和连接组件，预热管连接在连接组件上，预热管的出风口正对着产品输送装置上待奈印的产品。本发明中在产品进行奈印之前对产品的奈印部位进行预热；使得奈印时候，产品外壳奈印部位的温度在250℃‑300℃之间；这样产品完成奈印，进行回流焊的时候奈印产生的印字不易开裂。
