Description
Technical Field
The utility model relates to the technical field of bonding wire production, in particular to a bonding wire paying-off shaft disc.
Background
The bonding wire drawing production procedure is a process of drawing a wire rod with a large wire diameter to a small wire diameter.
The process involves front-end paying-off and terminal reeling-up operations of the bonding wire. The terminal wire-collecting is equipment linkage, the wire-drawing machine can realize wire-collecting operation, and no problem exists in the wire-drawing machine;
aiming at the paying-off part, active paying-off equipment is arranged on the current market, but the active paying-off equipment is high in price, the equipment occupies a large area, the utilization rate is low, and more processes of paying off wires from a spool are actually adopted under the action of tension.
The following problems exist in the current operation process:
the axis direction of the spool must be parallel to the wire inlet direction of the wire drawing machine, so that the wire can be coiled (like a spring) during paying-off, and the problem is unavoidable; if the axis of the spool is perpendicular to the wire inlet direction of the wire drawing machine, the wire can be linearly paid off, the winding condition does not occur, but the paying-off mode needs the wire to pull the whole wire to rotate together, the wire pulling force is large, the wire is easy to break, and the wire drawing process is unstable. The advantages and disadvantages are weighed, and the wire is fed in a mode that the axis direction of the spool is parallel to the wire feeding direction of the wire drawing machine.
On the premise that the winding can be generated when paying off can not be changed, the current production practice is that the hair is stuck at the position of the spool edge, the spool edge height is increased by phase change, and excessive wires are paid out once after pulling is prevented. The pasting mode is complex, low in efficiency, easy to fall off and low in overall stability.
To sum up, the bonding wire paying-off spool is lack of improvement on the existing pasting mode, can be directly clamped on the spool, achieves quick installation, improves efficiency, and can improve overall stability.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides a bonding wire paying-off shaft disc, which solves the problems in the prior art.
In order to solve the technical problem, according to one aspect of the utility model, the wire bonding paying-off shaft disc comprises a chuck, wherein three clamping claws are fixed on the upper surface of the chuck, three clamping grooves are formed in the upper surface of the chuck, opposite ends of the three clamping grooves extend to the outer surface of the chuck, buckles are arranged in the clamping grooves, sliding grooves are formed in the left side and the right side of the buckles in a penetrating mode, burrs are arranged below the buckles in the clamping grooves, sliding rails are connected in the sliding grooves in a sliding mode, and the two sliding rails are fixedly connected with the inner surfaces of the clamping grooves.
Furthermore, the edge of the outer surface of the buckle is frosted, so that the friction force between the outer surface of the buckle and the inner surface of the clamping groove is increased.
Furthermore, the hair is a single filament made of soft materials.
Furthermore, the top ends of the hair are positioned above the clamping grooves, and the opposite ends of the three hair are positioned outside the chuck.
Further, the chuck is of a circular ring structure.
Furthermore, the opposite ends of the tops of the three clamping claws are all in arc-shaped structures.
The bonding wire paying-off shaft disc has the beneficial effects that:
when the novel hair clamp is used, the hair is placed in the clamping groove, proper lengths are reserved at the top and the two ends of the outer side, the buckle is installed in the clamping groove along the sliding rail, and finally the hair is extruded and fixed by the buckle in the clamping groove and is in an L-shaped form; after the hair is installed with the buckle, the hair and the buckle do not need to be frequently disassembled, namely, the hair and the buckle form a whole with the chuck, and when the hair clamp is used, the chuck only needs to be directly clamped on the spool, and the chuck can be clamped with the spool through the arc protruding structures of the three clamping jaws, so that the hair clamp can be used for realizing rapid installation operation, and has the advantages of convenience in use, rapid disassembly and installation, high efficiency, recycling and the like.
