Description

Flange spool for winding

Technical Field

The utility model relates to a spool field specifically is a flange spool for wire winding.

Background

The gold bonding wire and the copper bonding wire are used for bonding an electrode on an integrated circuit silicon wafer and a lead frame, and are important welding materials in the field of semiconductors. Usually, a gold bonding wire and a bonding copper wire are wound regularly on the bobbin, when the gold bonding wire/the bonding copper wire are wound, the bobbin needs to be fixed by using a clamp, at present, the inner hole of the bobbin is supported by a clamping jaw to be fixed, although the positioning is fast and the fixing effect is good, the bobbin is supported and deformed due to the fact that the force of the clamping jaw is not good, and the manufacturing difficulty of winding of the gold bonding wire/the bonding copper wire is caused.

In our spool product, convenient fixed when convenient follow-up use, have the spool that has the ring flange, we improve based on this kind of spool, developed a spool and clamping anchor clamps of the joint clamping of being convenient for.

SUMMERY OF THE UTILITY MODEL

For solving prior art's not enough, the utility model provides a wire winding is with flange spool, it carries out the joint clamping, has avoided the hole to be propped the deformation by the clamping, has ensured the circularity of spool, makes the wire winding of gold bonding wire bonding copper wire accomplish smoothly.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:

the utility model provides a flange spool for wire winding, includes the barrel, barrel one end sets up the flange, the barrel another side sets up the flange, have a plurality of flange holes on the flange, wherein a pair of flange hole both sides relative all set up the arc wall.

The arc wall is a countersunk groove, the width of the outer side of the arc wall is larger than that of the inner side of the arc wall, a blocking piece is arranged on the outer side of the arc wall, and a clamping groove is formed between the blocking piece and the inner bottom surface of the arc wall.

The two arc-shaped grooves are symmetrically arranged.

The diameter of the flange is consistent with that of the flange.

Contrast prior art, the beneficial effects of the utility model are that:

the utility model discloses carry out technical transformation with former flange dish spool, make wherein two flange hole both sides of ring flange increase and set up the arc wall, utilize draw-in groove on the arc wall to carry out the joint to the clamping instrument to it rotates to utilize the spool that drives after the clamping instrument of wire winding lathe clamping. The device replaces a mode that the chuck supports the inner hole to clamp and fix the bobbin, prevents the bobbin from being damaged and deformed by external force, and ensures smooth completion of wire winding of gold bonding wires/copper bonding wires.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

As shown in figures 1-4, a winding flange spool, this spool improves on original product foundation structure and forms, mainly designs because the clamping takes place the problem of deformation to present spool winding in-process barrel, and the clamping mode of spool when changing the wire winding guarantees the structural stability when the spool is wound.

The utility model provides a flange spool for wire winding, this spool include

barrel

1, 1 one end welding of barrel or integrated into one

piece flange

2, 1 another side welding of barrel or integrated into one piece flange 3, a plurality of flange holes 31 have on the flange 3, and flange hole 31 is the circumference equipartition on the flange. Arc-shaped grooves 32 are processed on two sides of the pair of opposite flange holes 31. The arc-shaped groove 32 is a countersunk groove, that is, the width of the outer side of the arc-shaped groove 32 is larger than that of the inner side, so that a circular platform is formed at the bottom in the arc-shaped groove 32. A blocking piece 33 is arranged on the outer side of the arc-shaped groove 32, and a blocking groove 34 is formed between the blocking piece 33 and the bottom surface of the inner side of the arc-shaped groove 32. The bobbin can be a metal bobbin or a plastic bobbin, and is preferably cast and injection molded, and the device is integrally molded in a mold.

This spool cooperation special fixture uses, and this anchor clamps include that center pin and two are participated in, and two are participated in the bottom and have the inserted sheet, and two are participated in and fix on the center pin, and two are participated in and are corresponded with two arc walls respectively. When the clamping fixture is used, the two plug pins are respectively inserted into the flange holes in the centers of the arc-shaped grooves, then the central shaft is rotated to enable the insertion pieces to be clamped into the clamping grooves on one side of the central shaft for fixation, so that the clamping fixture is clamped, and then the central shaft is clamped on a winding machine tool. Wherein the inserted sheet is the prototype, and the diameter of inserted sheet is unanimous with arc wall outside width.

When the clamp is clamped and clamped, the ring table at the bottom of the bobbin is used for positioning, the inserting piece is proved to be contacted with the ring table after contacting with the ring table, and the inserting piece can be clamped into the clamping groove by directly rotating the bobbin or the clamp to complete the inserting and clamping.

Because the arc wall 32 all has the setting in the both sides in flange hole to when carrying out the installation of anchor clamps, two reverse installations of optional, thereby can realize the forward and the reverse drive of spool, satisfy the wire winding and the unwrapping wire operation of spool.

Preferably, two of the arc-shaped slots 32 are symmetrically arranged. When the symmetrically arranged arc-shaped grooves 32 are used for installing the clamp, the front side and the back side do not need to be considered, and the clamping of the clamp can be quickly realized.

Preferably, the diameter of the flange 3 is consistent with that of the flange 2, so that the arrangement of the bobbins can be more uniform in the processes of packaging and transporting the bobbins.

The bobbin is redesigned by using the flange hole of the flange, so that the bobbin can be clamped and clamped, the deformation caused by clamping of the inner hole supporting claw is avoided, and the wire winding of gold bonding wires/copper bonding wires can be smoothly completed.
