Problems solved by technology
The lead frame is stamped by a high-precision mold. However, there are the following obvious deficiencies in the stamping process: after the stamping is completed, the formed lead frame needs to be unloaded, but the existing unloading structure is inefficient. The operation time is long; at the same time, the existing unloading structure does not have an automatic reset function, which may easily cause the punching machine to punch when the unloading mechanism is not reset, and damage the mold

Embodiment Construction
[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0015] see Figure 1-2 , the present invention provides a technical solution:
[0016] An unloading mechanism with a reset function, used for unloading the lead frame after stamping and forming, and realizing automatic reset, including an unloading plate 1, which is movably arranged on the bottom mold through a reset device, and the unloading plate 1 Closely fit with the bottom mold, there is a groove 2 on the unloading plate 1, and a handle 6 is provided on ...

The invention discloses a discharging mechanism with a reset function. The discharging mechanism comprises a discharging plate, the discharging plate is arranged on a bottom die through reset devices,the discharging plate and the bottom die are closely attached, the reset devices comprise guide rails, reset springs and sliding blocks, the guide rails are arranged on the two sides of the bottom die, the sliding blocks are arranged on the two sides of the discharging plate and connected to the guide rails in a sleeving mode, and the reset springs used for driving the discharging plate to automatically reset along the guide rails are arranged between the guide rails and the sliding blocks. By arranging the discharging plate and arranging the reset springs on the guide rails, complete discharging can be conducted at a time after one-time punching, and the production efficiency is greatly improved; and meanwhile, through arrangement of the reset springs, the situation that staff work underthe situation that the discharging plate is not reset, and consequently, the die is damaged can be effectively avoided.
Description
technical field [0001] The invention relates to the technical field of lead frame production equipment, in particular to an unloading mechanism with reset function and a punching machine thereof. Background technique [0002] As the chip carrier of integrated circuits, the lead frame is a key structural part that realizes the electrical connection between the lead-out end of the chip's internal circuit and the outer lead by means of bonding materials (gold wire, aluminum wire, copper wire), and then forms an electrical circuit. The frame acts as a bridge to connect with the external wires. Most of the semiconductor integrated blocks need to use the lead frame, which is an important basic material in the electronic information industry. The lead frame is stamped by a high-precision mold. However, there are the following obvious deficiencies in the stamping process: after the stamping is completed, the formed lead frame needs to be unloaded, but the existing unloading structur...
