Problems solved by technology

Since the pins of the dual-in-line integrated block are usually many and the spacing is small, if you cannot ensure that each pin is completely vertical and consistent when plugging in, it cannot be inserted into the board, which is more likely to cause damage to the pins, resulting in Manifold scrap
[0003] The pins of the integrated block are not completely vertical, resulting in too large a double-row pin spacing
In the existing techno

example 1

[0026] The double-in-line integrated block pin shaping device includes a base 3 , a bracket 1 , and a cylindrical rolling bearing 2 . The support 1 is fixed on the base 3 with studs, and there are two rolling bearings 2, which are installed on both sides of the support 1 respectively. Base 3 weighs 1000g. The radius of the cross-section of the two rolling bearing cylinders is the same, and the rolling bearings can rotate freely.

[0027] The support is a strip profile, which is divided into upper and lower parts. The upper part can just place the dual in-line integrated block, so that the pins are on both sides of the profile, and the width of the two sides of the lower part is slightly larger than the width of the same position of the upper part, and the difference between the two widths is not less than the thickness of the pins. This structure makes the cylindrical rolling bearings close to the two sides of the lower part of the bar profile, while leaving a gap with the t...

[0031] The double-in-line integrated block pin shaping device includes a base 3 , a bracket 1 , and a cylindrical rolling bearing 2 . The bracket 1 is fixed on the base 3, and there are two rolling bearings 2, which are installed on both sides of the bracket 1 respectively. Base 3 weighs about 1000g. The radius of the cross-section of the two rolling bearing cylinders is the same, and the rolling bearings can rotate freely.

[0032] The bracket 1 is composed of two parallel movable brackets, and the two movable brackets and their corresponding rolling bearings are respectively installed on the base 3 through studs, and can move along a straight line where the two rolling bearings are located. The base 3 is provided with a guide rail 4 corresponding to the stud, and the stud moves along the guide rail 4 . The guide rail 4 is respectively provided with screw holes at the distances of the two movable supports at 7.4 to 7.62mm, 10.16mm, 12.7mm and 15.24mm.

Abstract

The method comprises: a) placing the IC chip on the fixture in order to make two columns of pins of the IC chip are respectively located at two sides of the fixture; the shape of the fixture corresponds to the shape formed by the IC chip two columns of pins and the IC chip; b) using a rotated cylinder to roll the pins in order to make press on the pins. The invention also reveals a device thereof comprising a base, a fixture, a cylinder rolling bearing; the fixture is mounted on the base; there are two rolling bearing respectively mounted on both side of the fixture.

Description

technical field [0001] The invention relates to a method and device for processing electronic products, in particular to a method and device for shaping the pins of a dual in-line integrated block. Background technique [0002] In recent years, electronic communication, IT, automation and other industries have achieved unprecedented rapid development, and electronic products have become indispensable consumer goods in people's lives today. Therefore, the demand and production volume of electronic products are very large, especially the frequency of use of integrated blocks of key components is quite high. Before the printed circuit board of electronic products is processed and welded, whether it is manual welding or wave soldering machine welding, device insertion including integrated blocks must be performed, and the insertion of integrated blocks is the most difficult and most important in the insertion process. Since the pins of the dual-in-line integrated block are usua...
