Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bonding device for semiconductor bonding wire, specifically a wire handling mechanism, a tension roller, a traverse mechanism, and a wire cutting machine, and a bonding wire that is fed out from a supply spool of a self-supply mechanism. The present invention relates to an improvement in a winding system in which a wire is wound on a four-winding gear of a four-window mechanism via a tension roller.

In the conventional winding device, a DC motor is installed in the winding mechanism, the winding spool is operated automatically, and the wire is drawn out from the supply spool by a pull-out method.
The traverse mechanism is configured so that the traverse mechanism is operated by interlocking the self-f motor with a belt or a transmission mechanism. .

However, in the conventional device, the wire supply mechanism uses a wire drawing method to bare the bonding wire, so that the force of the fed wire oscillates and varies greatly due to changes in the wire winding of the supply spool. The wire winding operation is unstable, so a tension roller is used, but the tension is difficult to handle.
Not only is it impossible to perform adjustment work during the first take-up operation, but even if a tension roller is used, there is a problem in that the drawn wire becomes slack when the winding is stopped.

In addition, the winding mechanism has uneven rotation due to the heavy use of the DC 7-tor
4 to the fixed position (wire hooking position) of the spool r, it is i-+, and because it is 4 dots, extra wire may be inserted, and furthermore, the traverse mechanism is a micro switch, and the response of sv- Due to the unevenness of the speed l history and the slipping of the clutch, there is unevenness in the main position and vinegar, and it is not possible to improve the side 1iysf* degree, and the pitch has to be changed.
Due to the pulling method, 4 pitches were obtained, but there were also problems such as the structure being forged. A driving mechanism consisting of a servo motor or a pulse motor is installed in each mechanism of the @trading structure, and the first speed of the wire fed out to the tension roller is subjected to tortoise pressure.
1115I is provided with a tensioner section that fully controls the tension of the wire, and the central processing unit is used to control the RDM source and the tensioner section. bl
The structure of the device is simplified, the workability is made easy, and the winding is easy! The purpose is to raise the pitch by lllll.

The conventional method of pulling out the wire from the supply spool by rotating the take-up spool has been adopted. 1. The wire is softened by the rotation of the take-up spool, and there is less variation in the alignment of the wire, and the tensioner part of the tension roller applies a constant tension of 751 r to the wire. Since the drive unit of the feeding mechanism is controlled via the central processing unit, the tension of the feeding wire is set at a constant value of 7Jr (+ machine running state or 14' stage). The wire can be taken up onto the take-up spool while being held in place, and the wire can be taken up in a good manner on the take-up spool.
