Embodiment Construction

[0022] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] like figure 1 As shown, a method for controlling the roundness of pressed glass insulators is used to control the roundness of glass insulators 10 discharged from the debinding vitrification equipment, including the following steps:

[0024] S1: Debinding and vitrification equipment removes glue and generates glass insulators in an effective temperature zone with a uniform temperature field;

[0025] S2: Use the heat insulation device as the adhesive carrier to undertake the glass insulator;

[0026] S3: Reject unqualified glass insulators by using shaker removal equipment.

[0027] Pressed glass insulators are made by firing the pressed glass powder body through vitrification and debinding.

[0028] In the initial stage of debinding and vitrification, the glass powder binder decomposes and volatilizes to get out of the green body. I...

Abstract

The invention discloses a roundness control method for a pressed glass insulator, which is used for controlling the roundness of a glass insulator discharged by glue discharging and vitrifying equipment. The method comprises the following steps that: 1, the glue discharging and vitrifying equipment discharges glue in an effective temperature area with a uniform temperature field and generates theglass insulator; 2, a heat insulation device is used as a glue discharging carrier to bear the glass insulator; and 3, unqualified glass insulators is rejected by using shaking type rejecting equipment. By controlling the temperature uniformity degree of an effective temperature zone of production equipment, the screen tray is used for bearing the glass insulators, so that the glass insulators arenot prone to deformation after glue discharging and vitrification, the glass insulators with the sizes reaching the standard are screened out through screening equipment, and the roundness of products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of packaging shells, in particular to a method for controlling the roundness of a pressed glass insulator. Background technique [0002] In the field of electronic components, the metal shell is not only the coat of the package chip, but also supports it, and is also an important part of the electronic components. [0003] The metal shell is composed of chassis, pressed glass insulator and lead wires which are sintered at high temperature. The pressed glass insulator is the key part of the metal shell, which plays the role of pressure resistance, insulation and sealing. [0004] During the preparation, the glass powder is firstly pressed into a green body, and then the binder is removed through the debinding process, and then vitrified into a glass insulator with a certain size and strength and a uniform surface color. [0005] In the prior art, the pressed glass insulator is prone to deformation after degl...
