Description

Technical Field

[0001] The utility model belongs to the technical field of chip processing, and more specifically, particularly relates to a chip pin bending device. Background Technique

[0002] With the increasingly wide application of chips in high-precision equipment, the requirements for the bending quality of chip pins are getting higher and higher. Pins are the wiring leads from the internal circuit of the chip to the peripheral circuit, and all the pins constitute the interface of this chip. The purpose of pin bending is to deform the pins of the chip into the expected shape by mechanical means to meet the process requirements during the insertion process.

[0003] In the prior art, the bending device usually fixes the chip by means of a fixed seat, and then synchronously bends the pins on one side of the chip by the bending head. It has a relatively high processing efficiency for one-side bending. However, if it is necessary to perform different types of bending on multiple groups of pins on one side of the chip, such as bending a row of pins into two columns, it is difficult to apply and has certain limitations in use. Therefore, in view of this, the existing structure and deficiencies are studied and improved to provide a chip pin bending device in order to achieve a more practical value purpose. Content of the Utility Model

One side of the supporting block is fixedly connected to a bending knife. The top of the linear module two is connected with a fixing table. The top of the fixing table is connected with a pneumatic gripper.

[0006] As a preferred technical solution of the present utility model, the linear module further includes a lead screw connected between two sets of the fixing plates. One end of the lead screw is in transmission connection with a driving motor. Both sides of the lead screw are fixedly connected with optical axes. A connecting seat is sleeved on the outer surface of the optical axis. A ball sleeve is sleeved on one side of the bottom end of the connecting seat. The ball sleeve is in threaded cooperation with the lead screw.

[0007] As a preferred technical solution of the present utility model, two sets of linear modules are arranged perpendicular to each other.

[0008] As a preferred technical solution of the present utility model, the positioning knife is arranged vertically, and the folding knife is arranged horizontally.
