Description

Technical Field

[0001] The present invention relates to the technical field of rib cutting and glue removal equipment, and more particularly to a rib cutting and glue removal equipment for chip packaging. Background Art

[0002] The rib cutting and glue removal equipment used for chip packaging adopts an overall punching method to punch out the leads and ribs on both sides of the chip ceramic outline package integrated circuit at one time. The rib cutting and glue removal equipment not only has the effect of cutting ribs, but also has the effect of cutting and separating the waste glue generated at the edge of the packaged chip. The rib cutting and glue removal equipment also has the advantages of good cutting quality, high cutting efficiency, simple structure and low manufacturing cost.

[0003] The existing chip packaging cutting and glue removal equipment cannot accurately lock the position of the waste glue when cutting the excess waste glue in daily use, resulting in the inability to perform accurate and effective cutting when cutting the waste glue. In addition, the existing waste material is removed by using the upper and lower plates for extrusion cutting, and if the force is too great, the outer side of the chip will be broken during cutting, thereby affecting the cutting quality.

[0004] Existing chip packaging cutting and glue removal equipment will easily cause the chip to shift and affect its use when placing it due to the influence of waste materials and waste glue when cutting the chip ribs. In severe cases, it will cause damage to the chip, thus affecting the user experience of the equipment. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rib cutting and glue removal device for chip packaging to solve the problems existing in the above-mentioned background technology.

[0006] The present invention provides the following technical solution: a rib cutting and glue removal device for chip packaging, comprising a rib cutting machine box, the bottom of the rib cutting machine box is fixedly connected to a first spring, the bottom of the first spring is fixedly connected to a rib fixing plate, a right-angle cutting knife is provided on the outside of the rib fixing plate, the internal movably sleeved telescopic detection column, an air pressure control machine box is provided on the outside of the rib cutting machine box, the outside of the rib cutting machine box is fixedly connected to a compressed air pipe, the inside of the air pressure control machine box is movably sleeved with a cutter telescopic column, the outside of the cutter telescopic column is fixedly connected to a blade mover, the inside of the blade mover is movably connected to a waste cutting knife, the inside of the air pressure control machine box is movably sleeved with a circular pressure plate telescopic column, the bottom of the circular pressure plate telescopic column is fixedly connected to a rubber pressure plate, and the bottom of the rubber pressure plate is movably sleeved with a first trigger.

[0007] Furthermore, the inner movable sleeve of the rib fixing plate contacts the trigger base, and a trigger collision column is provided on the top of the trigger base.

[0008] Furthermore, the top of the rib cutting machine box is movably connected to the top pressure plate of the equipment, and the bottom of the top pressure plate of the equipment is provided with a rib cutting machine box moving groove.

[0009] Furthermore, the bottom of the top pressure plate of the equipment is fixedly connected to a metal cylinder, and a workbench is provided at the bottom of the metal cylinder.

[0010] Furthermore, a cylindrical slot is provided on the outside of the workbench, the inside of the cylindrical slot is fixedly connected to a second spring, and the top of the second spring is fixedly connected to a rubber round pad.

[0011] Furthermore, the outside of the cylindrical slot is fixedly connected to a conductive copper sheet, and the outside of the rubber round pad is fixedly sleeved with a conductive copper ring.

[0012] Furthermore, a waste cleaning groove is provided on the top of the workbench, and the interior of the waste cleaning groove is fixedly connected to the chip placement groove.

[0013] Technical effects and advantages of the present invention: 1. This invention utilizes a right-angled cutter mounted on the bottom of the rib cutting machine housing to press down, while simultaneously pressing down on the rib fixing plate mounted on the bottom of the first spring. When the force is applied, the rib fixing plate triggers the telescopic detection column to extend and retract. This detection is performed at the edge of the packaged chip. If any excess adhesive is detected blocking its downward extension, the position of the excess adhesive is detected and recorded, automatically triggering a cutting command. The waste cutter within the blade mover then moves to the appropriate position, pressing down to remove the excess adhesive.

[0014] 2. When the present invention uses a right-angle cutter to cut excess chip ribs, the rubber pressure plate simultaneously presses down and secures the packaged chip. A first trigger installed within the rubber pressure plate presses against the packaged chip, thereby triggering the high-air switch of the compressed air pipe. The air from the compressed air pipe then blows the waste rubber separated by the right-angle cutter into a waste material cleaning trough, thus preventing residual waste rubber from affecting the placement of packaged chips on the equipment.
