Embodiment 1

[0040] The pins of a ceramic small outline package device need to be trimmed, and the metal pins protrude from the bottom of the device and are symmetrically distributed on both sides. The device body is made of ceramics, and the place where the ceramic body contacts the metal pins is brazed and welded, and the strength is weak. Such as figure 2 , place the device in the pin cutting device, first pull up the 2-2 telescopic shaft pull rod, rotate it 90° and place it in the groove on the top of the 2-1 telescopic shaft body, at this time the telescopic shaft final shaft retracts upward threaded telescoping shaft body. Then several devices 2-3 are placed in the groove with the body facing down, and the size of the body matches the width of the groove.

[0041] With the telescopic shaft kept pulled up, place the limit pressure block under the telescopic shaft and above the notch. Insert the pressing block boss 2-6 into the groove, and then put down the pressing block as a whol...

Abstract

The invention relates to a telescopic shaft positioning and pressing type device pin bilateral cutting device, comprising two symmetrically distributed telescopic shafts, a limit base body for carrying a device, a pressing block and two supporting wing blocks; the telescopic shaft is fixed on the limit base body On the upper part, the pressing shaft faces the groove in the limit base body, the pressing block is located between the telescopic shaft and the limit base body groove, and is used for pressing the device to be cut. Advantages: The device has low manufacturing cost and easy operation. At the same time, it selectively presses some pins of the device to ensure that the root of the component pins is not torqued during cutting, and can realize cutting multiple devices at one time, which is suitable for ceramic packaged devices. Fast loading and unloading of components is achieved through elastic telescopic shafts. The grooves limit the length of the device pins, and are also the basis for supporting and clamping the pins and protecting the vulnerable parts of the pins. The wing blocks on both sides of the base body are used to ensure overall stability, and the positions of the wing blocks can be replaced, so as to conform to the cutting operation of the left and right hands or cutting tools.

Description

technical field [0001] The invention relates to a telescopic shaft positioning and pressing device pin bilateral cutting device, which belongs to the technical field of integrated circuit pin cutting. Background technique [0002] In the process of integrated circuit manufacturing and packaging, there is often a wire frame connecting the pins of multiple integrated circuits. After the mass production of integrated circuits, the pins or wireframes are often shaped and cut by a cutting machine, and each integrated circuit block is separated into standard and consistent specifications before shipment. The rib cutting machine uses pneumatic or hydraulic pressure as the power, and is equipped with blanking dies with different costs, and an automatic feeding device to adapt to mass production. The mass-produced rib cutting machine can cut tens of millions of ribs a year. [0003] For experiments or small batch production, due to the limited number of products, the annual cutting...
