Description

Technical Field

[0001] This utility model relates to the field of composite carrier tapes, specifically to composite carrier tapes with antistatic conductive structures. Background Technology

[0002] Composite carrier tape is a high-performance carrier material used for the packaging and transportation of electronic components. It is typically composed of multiple layers of thin films with different functions. Its features include high-precision positioning, anti-static properties, moisture resistance, and high-temperature resistance. Suitable for automated production processes such as SMT (Surface Mount Technology), it effectively protects sensitive components from physical damage and environmental influences, improving production efficiency and reliability. It is widely used in semiconductors, consumer electronics, and other fields.

[0003] In existing carrier tape technologies, there is a general lack of effective anti-static design, and static electricity is easily accumulated, which may damage internal components. At the same time, it is difficult to balance the insulation and conductivity of the carrier tape, making it difficult to achieve good static electricity conduction. In addition, the carrier tape has insufficient tear resistance and a short service life. Moreover, when the carrier tape is subjected to external impact or vibration, there is a lack of buffering mechanism, which can easily damage internal components. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned deficiencies by providing a composite carrier tape with an antistatic conductive structure. This enhances the antistatic effect, improves the tear resistance of the composite carrier tape, and effectively reduces damage to internal components. It solves the technical problems of existing technologies where static electricity easily accumulates, potentially damaging internal components, and the carrier tape's insufficient tear resistance easily damages internal components.

[0005] The objective of this utility model is achieved through the following means:

[0006] A composite carrier tape with an antistatic conductive structure includes a composite carrier tape shell. The surface edges of the composite carrier tape shell are provided with conductive grooves. The upper part of the composite carrier tape shell is a PET insulation layer. A carbon fiber bundle woven mesh is installed at the bottom of the PET insulation layer. A tear-resistant modified PP layer is installed at the bottom of the carbon fiber bundle woven mesh. Cavities are evenly distributed on the surface of the composite carrier tape shell. Fixing blocks are installed in the inner cavities of the cavities. Springs are installed on the surface of the fixing blocks.

[0007] Furthermore, the surface of the composite carrier belt shell is uniformly distributed with positioning holes, which are equidistantly distributed along the length of the composite carrier belt shell. The opening positions of the positioning holes are carefully designed to achieve precise positioning and docking with various external devices, ensuring the stability of the composite carrier belt during installation and use. The inner wall of the positioning hole is provided with annular raised anti-slip textures, which form an interference fit with the positioning pin of the external conveying equipment. This design can increase the friction between the positioning hole and the positioning pin, avoid relative displacement caused by vibration during conveying, and improve the stability of the carrier belt operation.

[0008] Furthermore, a limiting rod is installed on the surface of the fixing block, and limiting grooves are formed on the inner wall of the cavity at positions corresponding to the limiting rods. The matching design of the limiting rods and limiting grooves can effectively limit the movement range of the fixing block, prevent excessive displacement within the cavity, and ensure the reliability of the fixing block's operation. The opening of the limiting groove is provided with an outwardly inclined guide slope, and the depth of the limiting groove gradually increases along the direction closer to the center of the cavity. The guide slope can guide the limiting rod to quickly embed into the limiting groove, and the structure of increasing depth can ensure that the limiting rod can achieve stable positioning under different compression states, enhancing the fixing block's adaptability to clamping components.

[0009] Furthermore, a shock-absorbing pad is installed on the inner wall of the cavity. The shock-absorbing pad is in close contact with the surface of the fixing block. The surface of the shock-absorbing pad is provided with honeycomb-shaped shock-absorbing holes. The design of the honeycomb-shaped shock-absorbing holes can enhance the shock-absorbing effect of the shock-absorbing pad, effectively absorb and disperse vibration energy from the outside, and reduce the impact on the internal components of the composite carrier belt. The diameter of the honeycomb-shaped shock-absorbing holes gradually decreases from the side near the fixing block to the side of the inner wall of the cavity. The shock-absorbing pad is made of conductive silicone and is electrically connected to the carbon fiber bundle woven mesh. The gradual diameter design can achieve graded shock absorption and improve the buffering effect. At the same time, the conductive silicone can conduct static electricity on the surface of the components through the carbon fiber bundle woven mesh, which enhances the anti-static performance.

[0010] Furthermore, the inner cavity of the guide channel is designed with a sawtooth shape, and the tooth shape of the guide channel is an isosceles triangle. The sawtooth design can increase the surface area of ​​the inner wall of the guide channel, so that more turbulence is generated when the fluid flows in the guide channel, thereby improving the guiding efficiency. At the same time, the isosceles triangle tooth structure has a certain stability and is not easily deformed. The tips of the sawtooth structure are all rounded, and micro conductive bumps are provided on the bottom of the channel between adjacent sawtooths. The rounded corners can avoid wear on the tooth tips and extend the service life of the guide channel. The micro conductive bumps can increase the static electricity discharge path and improve the anti-static efficiency of the guide channel.

[0011] Furthermore, the inner wall of the guide channel is coated with a nanoscale conductive coating, which is made of silver paste or carbon nanotubes. The conductive coating forms a conductive path with the carbon fiber bundle woven mesh. The nanoscale conductive coating has excellent conductivity and can quickly conduct static electricity away. The conductive path formed with the carbon fiber bundle woven mesh can further enhance the antistatic capability of the composite carrier tape and effectively avoid damage to the electronic components inside the carrier tape caused by static electricity.

[0012] Furthermore, the contact surfaces of the carbon fiber bundle woven mesh with the PET insulation layer and the tear-resistant modified PP layer are all fixed by hot melt adhesive film, and conductive particles are uniformly dispersed in the hot melt adhesive film. The conductive particles simultaneously form an electrical connection with the carbon fiber bundle woven mesh and the nanoscale conductive coating. The conductive particles can eliminate the interfacial resistance between the layers, allowing static electricity to be quickly conducted to the conductive coating through the multilayer structure, further optimizing the conductivity efficiency of the antistatic pathway.

[0013] The beneficial effects of this invention are as follows: When static electricity is generated, the added guide channel can be guided along the guide channel, effectively preventing static electricity accumulation and achieving anti-static function; the PET insulation layer and the carbon fiber bundle woven mesh work together, with the PET insulation layer providing insulation and the carbon fiber bundle woven mesh being conductive, the combination of the two ensures both insulation and facilitates static electricity conduction, further enhancing the anti-static effect; the carbon fiber bundle woven mesh is combined with the tear-resistant modified PP layer, which improves the tear resistance of the composite carrier tape shell and extends its service life;

[0014] The composite carrier tape outer shell has cavities evenly distributed on its surface. Fixing blocks are installed inside the cavities, and springs are installed on the surface of the fixing blocks. The springs can act as a buffer, effectively reducing damage to internal components when the composite carrier tape is subjected to external impact or vibration. Attached Figure Description

The surface of the composite carrier tape shell 1 is uniformly distributed with cavities 6. Fixing blocks 7 are installed in the cavities 6, and springs 9 are installed on the surface of the fixing blocks 7.

In addition, the inner wall of the positioning hole 8 is provided with annular raised anti-slip texture. The anti-slip texture forms an interference fit with the positioning pin of the external conveying equipment. This design can increase the friction between the positioning hole 8 and the positioning pin, avoid relative displacement caused by vibration during the conveying process, and improve the stability of the carrier belt operation.

[0023] A limiting rod 10 is installed on the surface of the fixing block 7. A limiting groove 11 is opened on the inner wall of the cavity 6 at the corresponding position of the limiting rod 10.

The opening of the limiting groove 11 is provided with an outwardly inclined guide slope, and the depth of the limiting groove 11 gradually increases along the direction close to the center of the cavity. The guide slope can guide the limiting rod 10 to quickly embed into the limiting groove 11, and the structure of increasing depth can enable the limiting rod 10 to obtain stable limiting under different compression states, enhancing the clamping adaptability of the fixing block 7 to the component.

The surface of the shock-absorbing pad 12 is provided with honeycomb-shaped shock-absorbing holes. The design of the honeycomb-shaped shock-absorbing holes can enhance the shock-absorbing effect of the shock-absorbing pad 12, effectively absorb and disperse the vibration energy from the outside, and reduce the impact on the internal components of the composite carrier belt. The diameter of the honeycomb-shaped shock-absorbing holes gradually decreases from the side near the fixing block 7 to the side of the inner wall of the cavity. The shock-absorbing pad 12 is made of conductive silicone and is electrically connected to the carbon fiber bundle woven mesh 4. The gradual change in the diameter of the holes can achieve graded shock absorption and improve the buffering effect. At the same time, the conductive silicone can conduct static electricity on the surface of the components through the carbon fiber bundle woven mesh 4, which can enhance the anti-static performance.

[0025] The inner cavity of the flow guide channel 2 has a sawtooth design, and the teeth of the flow guide channel 2 are isosceles triangles. The sawtooth design can increase the surface area of ​​the inner wall of the flow guide channel 2, so that more turbulence is generated when the fluid flows in the flow guide channel 2, thereby improving the flow guide efficiency. At the same time, the isosceles triangle tooth structure has a certain stability and is not easily deformed. The tips of the sawtooth structure are all rounded.

The conductive coating and the carbon fiber bundle woven mesh 4 form a conductive path. The nano-level conductive coating has excellent conductivity and can quickly conduct away static electricity. The conductive path formed with the carbon fiber bundle woven mesh 4 can further enhance the antistatic ability of the composite carrier tape and effectively avoid damage to the electronic components inside the carrier tape by static electricity.

[0027] The contact surfaces of the carbon fiber bundle woven mesh 4 with the PET insulation layer 3 and the tear-resistant modified PP layer 5 are all fixed by hot melt adhesive film. The hot melt adhesive film contains uniformly dispersed conductive particles. These conductive particles also form an electrical connection with the carbon fiber bundle woven mesh 4 and the nanoscale conductive coating. The conductive particles can eliminate the interfacial resistance between the layers, allowing static electricity to be quickly conducted to the conductive coating through the multilayer structure, further optimizing the conductivity of the antistatic path.

[0028] In this embodiment, the composite carrier tape shell 1 has serrated guide grooves 2 on its surface edge and its inner wall is coated with a nanoscale conductive coating made of silver paste or carbon nanotubes, forming a conductive path with the carbon fiber bundle woven mesh 4.
