Description

Technical Field

[0001] The utility model relates to the technical field of lead frame production, in particular to a copper strip reel. Background Art

[0002] When producing lead frames, the raw materials used are pure copper strips or copper-containing alloy strips. Usually, copper strip products enter the production area in the form of copper strip coils. During actual production, the copper strip coils need to be fixed on a rotating frame, unwound and transported by a conveyor device (usually a conveyor wheel) for use in subsequent processes.

[0003] However, copper strip rolls of different widths are sometimes used during production, and the center of the copper strip roll generally has an inner paper tube. However, the inner diameter of the inner paper tube of copper strip rolls of different specifications is different, and the commonly used copper strip roll turret cannot be adjusted according to different copper strip roll specifications. Different turrets are required to match different copper strip rolls, which is more complicated to operate. Utility Model Content

[0004] In view of the above-mentioned defects, the utility model provides a copper strip reel stand, which can match copper strip reels of different widths and with different inner paper tube inner diameters, thereby facilitating the production of lead frames.

[0005] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0006] A copper strip reel comprises a fixed swivel seat and:

[0007] The movable unit comprises a bottom plate, an upper end surface of which is provided with a concave frame, a moving plate is slidably fitted in the concave frame, and a movable rotating seat is provided on the upper end of the moving plate;

[0008] A rotating rod is rotatably engaged between the fixed rotating seat and the movable unit;

[0009] There are two groups of winding units. When working, each group is located at the two side ends of the copper strip roll. The multiple winding units of each group are respectively assembled on the outer peripheral side of the rotating rod in a circular array. The winding unit includes a pasting plate assembled on the flat groove. A side clamping plate is provided at one end of the pasting plate. One side surface of the side clamping plate matches one side end of the copper strip roll. The side surface of the side clamping plate is provided with an inner top plate. One end surface of the inner top plate matches the inner peripheral side surface of the inner paper tube of the copper strip roll.

[0010] Furthermore, a first side opening is formed through the upper side surface of the fixed rotating seat, one end of the rotating rod is rotatably fitted in the first side opening, and a second side opening is formed through the side surface of the movable rotating seat which is coaxial with the first side opening.

[0011] Furthermore, a first limiting plate is provided at one end of the rotating rod, an outer rod having a diameter the same as the inner diameter of the first side opening is provided at one end thereof, and a second limiting plate is provided at one end of the outer rod.

[0012] Furthermore, a plurality of first screw holes are provided at one end of the bottom surface of the concave frame, and a plurality of first through holes matching the first screw holes are provided downwardly on the movable plate. When the first through holes and the first screw holes are screwed together to fix the movable plate to one end of the concave frame, the other end of the rotating rod rotates and fits into the second side opening.

[0013] Furthermore, a plurality of planar grooves extending in a direction parallel to the axis of the rotating rod are provided in a circular array on the outer circumference of the rotating rod, two groups of third screw holes are provided in the planar grooves along their length direction, and a second through hole matching the third screw hole is provided on the plate. The winding unit is fixed to the rotating rod by screwing the second through hole and the third screw hole.
