Description

Technical Field

[0001] The utility model relates to the technical field of lead frames, in particular to an antioxidant storage structure for lead frames. Background Art

[0002] As a chip carrier for integrated circuits, a lead frame is a structure that realizes the electrical connection between the internal circuit leads of a chip and the external leads by means of bonding materials (gold wire, aluminum wire, copper wire). When storing the frame, the frame is placed in a container for storage. This storage structure is used to store lead frames.

[0003] When storing lead frames, they are generally stored in containers. Ordinary containers have a simple structure with an internal cavity for storing lead frames. When storing, the lead frames are stacked together, and it is easy for the lead frames to collide and wear against each other. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an antioxidant storage structure for lead frames.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An antioxidant storage structure for lead frames includes a storage dish. An inner cavity is formed inside the storage dish. Slide grooves are formed in the left and right end walls of the storage dish close to the inner cavity. Slide seats are installed inside the slide grooves. Screws are inserted through the end walls of the slide seats. A top cover is installed at the top of the storage dish. Cover buttons are installed at the left and right ends of the bottom of the top cover. A cover cavity is formed inside the top cover. A screw plate is inserted through the top end wall of the top cover. Mesh holes are formed in the bottom end wall of the top cover.

[0007] Preferably, the inner cavity and the slide grooves are connected and communicated with each other.

[0008] Preferably, the storage dish and the slide seats form a sliding structure through the slide grooves.

[0009] Preferably, the slide seats are threadedly connected to the screws, and the number of screws is three times the number of slide seats.

[0010] Preferably, the top cover is snap-connected to the storage dish through the cover buttons.

[0011] Preferably, the top cover is threadedly connected to the screw plate, and at the same time, the cover cavity and the mesh holes are connected and communicated with each other.

[0012] The utility model has at least the following beneficial effects:

[0013] 1. It moves through the sliding groove and the sliding seat, which is used to slide the sliding seat and change the height position of the sliding seat. The position of the sliding seat is controllable and adjustable, making it more flexible and convenient to use. Then, tighten the screw in the middle of the sliding seat to lock and limit the sliding seat after adjusting the position. After the two screws at the side end of the sliding seat rotate and protrude, use the screws to support the lead frame, so that the lead frames are separated by the screws to prevent collision and wear between the frames.

[0014] 2. Connect the top cover and the storage dish through the cover buckle, which is convenient for disassembling and assembling the top cover and the storage dish. Then, rotate the screw plate at the top cover to open the cover cavity, which is convenient for adding dry powder into the cover cavity. It breathes through the mesh holes to protect the inside of the storage dish from moisture, preventing the lead frames stored and received in the dish cavity from getting damp, corroded, and oxidized.

[0021] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will further describe the present invention in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution for an anti-oxidation storage structure of a lead frame:

[0023] Embodiment 1:

[0024] As Figures 1-4 shown, an anti-oxidation storage structure for a lead frame includes a storage dish 1. An inner cavity 2 is formed inside the storage dish 1. Slide grooves 3 are formed in the left and right end walls of the storage dish 1 close to the inner cavity 2. A slide seat 4 is installed inside the slide grooves 3. A screw rod 5 penetrates through the end wall of the slide seat 4. A top cover 6 is installed at the top of the storage dish 1. Cover buttons 7 are installed at the left and right ends of the bottom of the top cover 6. A cover cavity 8 is formed inside the top cover 6. A screw plate 9 penetrates through the top end wall of the top cover 6. A mesh hole 10 is formed in the bottom end wall of the top cover 6.

[0025] Embodiment 2:

[0026] Based on Embodiment 1, as Figure 1 and Figure 2 shown, the inner cavity 2 and the slide grooves 3 are connected and communicated. The storage dish 1 and the slide seat 4 form a sliding structure through the slide grooves 3. The slide seat 4 and the screw rod 5 are threadedly connected. And the number of the screw rods 5 is three times that of the slide seats 4. The slide seat 4 moves through the slide grooves 3 and the slide seat 4, which is used to slide the slide seat 4 and change the height position of the slide seat 4. The position of the slide seat 4 is controllable and adjustable, which is more flexible and convenient in use. And by tightening the screw rod 5 in the middle of the slide seat 4, it is used to lock and limit the slide seat 4 after adjusting the position. After the two screw rods 5 on the side end of the slide seat 4 rotate and protrude, the screw rods 5 are used to support the lead frame, so that the lead frames are separated by the screw rods 5, preventing bumps and abrasions between the frames;

[0027] Based on Embodiment 1, as Figure 3 and Figure 4 shown, the top cover 6 is snap-connected to the storage dish 1 through the cover buttons 7. The top cover 6 and the screw plate 9 are threadedly connected. At the same time, the cover cavity 8 and the mesh hole 10 are connected and communicated. By snap-connecting the cover buttons 7 to assemble the top cover 6 and the storage dish 1, it is convenient to disassemble and assemble the top cover 6 and the storage dish 1. And by rotating the screw plate 9 at the top cover 6, the cover cavity 8 is opened, which is convenient to add dry powder into the cover cavity 8. Through the air permeability of the mesh hole 10, the inner cavity 2 of the storage dish 1 is dried and protected, so that the lead frame stored and received in the inner cavity 2 is moisture-proof, preventing the frame from being affected by moisture, corrosion and oxidation.

[0028] Working principle: The sliding groove 3 and the sliding seat 4 are movably connected to slide the sliding seat 4 for displacement and change the height position of the sliding seat 4. The position of the sliding seat 4 is controllable and adjustable, making it more flexible and convenient to use. Tightening the screw rod 5 in the middle of the sliding seat 4 is used to lock and limit the sliding seat 4 after the position is adjusted. After the two screw rods 5 at the side end of the sliding seat 4 rotate and protrude, the lead frame is supported by the screw rods 5, so that the lead frames are separated by the screw rods 5 to prevent collision and wear between the frames. The top cover 6 and the storage dish 1 are connected by snap-fastening the cover buckle 7, which is convenient for disassembling and assembling the top cover 6 and the storage dish 1. The screw plate 9 at the top cover 6 rotates to open the cover cavity 8, which is convenient for adding dry powder into the cover cavity 8. Through the air holes 10 for ventilation, the storage dish 1 is dried and protected, so that the lead frames stored and received in the dish cavity 2 of the storage dish 1 are moisture-proof, preventing the frames from being affected by moisture, corrosion and oxidation.
