Technical Field

[0001] This utility model relates to the field of metal frame processing technology, specifically a metal frame stamping device. Background Technology

[0002] Semiconductor metal frames refer to the metal supports used in the semiconductor packaging process. They are usually made of metal materials, such as aluminum (Al) and copper (Cu). These metal supports play an important role in semiconductor production. Metal supports have high mechanical strength and high conductivity, which can ensure the stability and reliability of semiconductor devices during the packaging process. Commonly used metal materials include aluminum and copper. These materials perform well in electron beam lithography and welding processes. With the continuous advancement of semiconductor technology, the design and manufacturing of metal supports are also constantly being optimized.

[0003] When stamping semiconductor metal frames, the raw material needs to be placed on the lower die, and then the upper and lower dies are closed by a hydraulic rod to stamp the metal frame material. However, the metal frame material needs to be placed manually each time stamping is performed, and the formed metal frame is removed after stamping is completed. The overall production efficiency is not high and there are certain safety risks.

[0004] Therefore, this utility model provides a metal frame stamping device to solve the above problems. Utility Model Content

[0036] Example 2:

[0037] Please see Figure 1-5This embodiment provides a technical solution based on Embodiment 1: the feeding assembly 3 includes a support frame 39, the bottom wall of the support frame 39 is fixedly connected to the top wall of the workbench 2 and located on the left side of the lower mold 46, a placement frame 31 is fixedly installed on the top wall of the support frame 39, a plurality of stamping plates 32 are evenly placed inside the placement frame 31, a receiving cavity 35 is opened at the bottom of the left wall inside the placement frame 31, a through groove 37 is opened at the bottom of the right wall inside the placement frame 31, and connecting frames 38 are fixedly installed on the right side wall of the placement frame 31 at positions corresponding to the through groove 37.

[0038] In this embodiment of the utility model, the purpose of this setting is that the feeding component 3 can automatically feed materials during the stamping process, eliminating the need for manual feeding, thus providing good processing safety and preventing accidents. Furthermore, it can cooperate with the stamping component 4 to improve the production efficiency of semiconductor metal frames.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] During operation, the electric actuator 33, hydraulic rod 41, electric actuator 48, and conveying device 5 are first electrically connected via an external power supply and controller. The stamping sheet 32 ​​to be processed is first placed into the placement frame 31. The electric actuator 33 pushes the pusher seat 36 out of the receiving cavity 35 and drives the support plate 34 to slide into the placement frame 31. When the pusher seat 36 pushes the stamping sheet 32 ​​to the right, it slides into the inner wall of the connecting frame 38 through the groove 37. During the pushing, the support plate 34 will support the stamping sheet 32 ​​being pushed. Another stamped plate 32 above provides support to prevent it from falling. After the stamped plate 32 is pushed past the connecting frame 38, it continues to move above the lower die 46 until it comes into contact with the side wall of the baffle plate 417 to complete the feeding process. Then, the movable end of the electric push rod 33 retracts, driving the pusher seat 36 back into the inner wall of the receiving cavity 35, and causing the support plate 34 to slide to the left, thus causing the supported stamped plate 32 to fall, waiting for the next feeding. After feeding is completed, the hydraulic rod 41 pushes the lifting seat 44 and the upper die 45 to move downward. When seat 44 moves downward, it drives positioning rod 43 to move downward, preventing misalignment during the closing and stamping of upper die 45 and lower die 46. When upper die 45 and lower die 46 close and stamp the sheet metal 32, they drive top block 410 and sliding seat 411 to slide downward in the inner wall of mounting cavity 414. The sliding seat 411 then drives sliding block 412 to slide in the inner wall of limiting groove 415 and compress lifting spring 413. The waste material after stamping falls into the inclined discharge groove 49 and is discharged. When the movable end of hydraulic rod 41 retracts, upper die 45 and lower die 46... After demolding, the sliding seat 411 and the top block 410 are pushed by the elastic action of the lifting spring 413 to lift the stamped metal frame from the inner wall of the lower die 46. Then the movable end of the electric push rod 48 extends to push the push plate 47 close to the lower die 46 and push the lifted metal forward. The metal frame falls into the conveying equipment 5 after passing the unloading seat 416 and is then conveyed out. Then, the feeding assembly 3 is used to carry out the feeding and stamping process. The waste generated during the stamping process can be put into the inside of the waste frame 6 for unified collection.
