Background

Integrated circuit leadframes are the basic component for the manufacture of integrated circuit semiconductor elements. In order to meet the requirements for manufacturing semiconductor elements of integrated circuits, the surface local area of the lead frame of the integrated circuit needs to be electroplated with metallic silver or nickel-palladium-gold. The electroplating is a surface processing method for forming a coating by taking a plated base metal as a cathode in a salt solution containing a preplating metal and depositing cations of the preplating metal in the plating solution on the surface of the base metal through electrolysis.

The high-density integrated circuit lead frame to be plated is strip-shaped and is wound in an I-shaped tray, then the coiled lead frame and the tray are inserted outside the supporting shaft, and thus under the traction of external force, the strip-shaped lead frame continuously discharges materials and is plated forwards. The electroplated lead frame is wound by an I-shaped tray.

After a material tray wrapped with the lead frame to be electroplated is provided with the supporting shaft, the material tray needs to be clamped by a clamping mechanism, so that the material tray is prevented from being separated from the supporting shaft in the material placing process. After the tray releases the lead frame or rolls up the lead frame, the clamping mechanism needs to be disassembled to move the tray out.

However, the clamping relation between the existing clamping mechanism and the support shaft is complex, the operation time of workers is long, and the shaft changing speed is influenced.

Detailed Description

The present invention will be described in detail with reference to the following embodiments and accompanying drawings.

The charging tray quick detach mechanism in integrated circuit lead frame material area of this embodiment, as shown in fig. 1 to fig. 4, including support 1, cardboard 2 and elastic component 3, support 1 includes first pedestal 11 and the second pedestal 12 through bolt lock locking each other, cardboard 2 can swing inserts between first pedestal 11 and the second pedestal 12, second pedestal 12 is opened has the holding tank 121 that is "protruding" word shape that supplies 2 beat activities of cardboard, cardboard 2 is the shape of adaptation holding tank 121.

The elastic member 3 is a spring, the first seat 11 is provided with a limit slot 111 for the elastic member 3 to insert, the snap-gauge 2 is provided with a limit post 21 for the elastic member 3 to sleeve, one end of the spring abuts against the support 1, the other end of the spring abuts against the snap-gauge 2, and a reset elastic force is applied to the snap-gauge 2, so that the snap-gauge 2 keeps a deflection clamping state as shown in fig. 3, and the snap-gauge 2 abuts against the second seat 12 in the deflection state. Cardboard 2 local extension is outside support 1 to supply external force operation to put card board 2 in right, cardboard 2 supports first pedestal 11 under the state of putting, and spacing post 21 inserts in spacing groove 111 this moment.
