Embodiment approach

[0017] As an embodiment of the present invention, see figure 1 , the present invention includes the following implementation steps

[0018] 1. Change the manual brushing of anti-rust oil to automatic soaking of anti-rust oil, so that the residual rubber channel produced by molding will automatically fall off when cutting the material.

[0019] 2. A diode molded double-row discharge seat invented for single-row seat discharge. The double-row discharge seat includes discharge teeth and oil immersion grooves distributed equidistantly. Lead wire grooves are provided on the discharge teeth corresponding to the oil immersion grooves, and the oil immersion grooves are filled with foam sponges. image 3

[0020] 2. The lead groove fixes the position of the lead wire in the oil immersion tank, so that the position of the lead wire colloid flow channel is accurately soaked in anti-rust oil. image 3

Abstract

The invention discloses a process for discharging during diode die-pressing. In the process, manual painting of antirust oil is replaced by automatic immersing of the antirust oil by optimizing a discharging fixture, so that a residual glue channel produced by die-pressing can fall off automatically during discharging. The invention has the advantages of simplifying the process step, improving the working efficiency and reducing the operating difficulty.

Description

technical field [0001] The invention relates to a diode molding and discharging seat and a new molding and discharging technology thereof. Background technique [0002] The process of diode molding and packaging is characterized by a large number of single dies and a short molding time for single dies. However, in actual operation, the diode molding and packaging process has colloid flow channels flowing onto the leads. Rubber residue. Lead defects are generated in subsequent processes. Apply anti-rust oil (CRC) to the position of the colloid flow channel of the lead to reduce the bonding strength of the colloid flow channel and make it easy to remove the residual rubber on the lead. The usual process is to manually apply anti-rust oil (CRC) with a brush on the position of the colloid flow channel. The way of manual brushing wastes a lot of time in the process of nesting, which affects the efficiency. Due to the manual brushing, the anti-rust oil (CRC) is applied to the ...
