Description

[0001] The present invention relates to an automatic assembling device for a probe pin,

The present invention relates to an apparatus for automatically assembling a probe pin, and more particularly, it relates to a probe pin automatic assembling apparatus, in which a sleeve, which constitutes a probe pin, and an upper, a lower plunger and an internal spring are assembled sequentially, And to reduce the manufacturing cost and to uniformize the quality of the probe pins.

Generally, a probe pin is mounted on a test socket for testing a device formed on a wafer and a semiconductor chip package, and transmits an electric signal between external connection terminals separated by a predetermined distance. Therefore, by analyzing the electric signal transmitted through the probe pin to check whether the product is defective, quality problems that may occur after shipment can be minimized.

As shown in FIG. 1, a conventional probe pin has a sleeve 1 having an upper stopping jaw 1a and a lower stopping jaw 1b facing inward at both ends thereof, An upper contact portion 2 mounted inside the sleeve 1 and a lower contact portion 3 mounted inside the sleeve 1 with an upper end fitted in the lower stopping jaw 1b and an upper contact portion 2 and a lower contact portion 3 And a coil spring 4 mounted inside the sleeve 1 so as to be positioned between the coil spring 4 and the coil spring 4.

The upper contact portion 2 is composed of a lower body portion 2a fitted in the sleeve 1 and an upper contact pin 2b extending vertically from the upper end of the lower body portion 2a. In addition, the lower body portion 2a has a step portion interfering with the upper stopping jaw 1a so that the lower body portion 2a is prevented from being separated from the sleeve 1 by the step portion.

 The lower contact portion 3 is composed of an upper body portion 3a fitted in the sleeve 1 and a lower contact pin 3b extending vertically from the lower end of the upper body portion 3a. The upper body portion 3a has a step portion interfering with the lower stopping jaw 1b to prevent the upper body portion 3a from being separated from the sleeve 1 by the stepped portion.

The conventional probe pin is manufactured through the following process.

The upper contact portion 2 and the lower contact portion 3, the coil spring 4 and the sleeve 1 (both ends are not bent) are manufactured respectively and then the coil spring 4 is wound around the sleeve 1 . The lower body portion 2a and the upper body portion 3a are inserted into both ends of the sleeve 1 so as to be opposed to each other with the coil spring 4 interposed therebetween and then the opposite ends of the sleeve 1 are inserted inward The manufacturing of the probe pin is completed with the upper contact portion 2 and the lower contact portion 3 mounted on the sleeve 1.

Conventionally, in the conventional assembly work, a worker picks up parts one by one while looking at a microscope or a monitor, manually assembles them, and relies only on manual work until the final caulking operation.

Therefore, such a conventional method of manufacturing a probe pin has a problem that the productivity is low and the manufacturing cost is reduced, and it is difficult to ensure the uniformity of the product quality.

Patent Literature 1 discloses a technique for reducing the number of parts and automating a manufacturing process by forming a sleeve forming a probe pin into a predetermined shape by drawing a plate material so as to improve productivity.

Patent Document 2 proposes a technique for manufacturing the upper contact portion, the lower contact portion and the elastic portion of the probe pin through a continuous process using a progressive metal mold and a press to simplify the production process and improve the productivity.

However, since probe pins of the type shown in FIG. 1 are still dominant rather than the probe pins shown in Patent Documents 1 and 2, it is necessary to develop a device capable of automatically assembling the probe pins.
