Description

Technical Field

[0001] This utility model relates to the field of electronic component packaging, specifically to the carrier body of embossed carrier tape and the embossed carrier tape. Background Technology

[0002] Embossed carrier tape is used to protect electronic components from contamination and damage during transportation. In use, the electronic components are placed into the carrier compartments of the tape and sealed with a cover tape, then wound onto a spool. Existing embossed carrier tapes are prone to sidewall deformation, especially for electronic components with long leads. If the sidewalls of the embossed carrier tape deform after placement, it can easily cause the electronic components to deform, leading to the risk of jamming and ultimately affecting the use of the final product. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a carrier body for embossed carrier tape and an embossed carrier tape itself.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A carrier body for an embossed carrier tape includes a strip body and a plurality of carrier grids spaced apart along the length of the strip body. Each carrier grid has a carrier cavities for accommodating electronic components. The carrier grid is characterized in that a portion of the bottom wall and / or a portion of the side wall of the carrier grid has a reinforcing portion.

[0006] The carrier tape body of this application increases its strength and reduces the risk of deformation by locally providing reinforcements on the bottom wall and / or side walls of the carrier grid, thus minimizing the risk of damage to electronic components. Furthermore, compared to increasing the overall thickness to improve the strength of the carrier tape body, locally providing reinforcements reduces material usage, lowers material costs, and reduces the weight of the entire roll of embossed carrier tape.

[0007] In one embodiment of the present invention, a portion of the bottom wall of the carrier grid has a reinforcing part, the reinforcing part of the bottom wall of the carrier grid is a first reinforcing part, and the first reinforcing part is a thickened layer.

[0008] In one embodiment of the present invention, the first reinforcing part is disposed around the bottom wall of the carrier grid.

[0009] The first reinforcing part is set around the bottom wall of the carrier grid. This setting can effectively increase the bottom strength of the carrier grid, and also requires less material and has a smaller increase in weight.

[0010] In practical applications, the bottom wall of the carrier grid has four sides, and the first reinforcing part is set at the four sides of the bottom wall of the carrier grid.

[0011] In one embodiment of the present invention, a portion of the sidewall of the carrier grid has a reinforcing part, and the reinforcing part of the sidewall of the carrier grid is a second reinforcing part, which is a reinforcing rib.

[0012] In one embodiment of the present invention, the second reinforcing part is located at the junction of the side walls of two adjacent carrier grids.

[0013] The second reinforcement is located at the junction of the side walls of two adjacent carrier grids. This arrangement can effectively increase the strength of the side walls of the carrier grids, while using less material and increasing the weight less.

[0014] In one embodiment of the present invention, the second reinforcing part is located on the outer side of the sidewall of the carrier grid.

[0015] In one embodiment of the present invention, a portion of the bottom wall of the carrier grid has a reinforcing portion, the reinforcing portion of the bottom wall of the carrier grid being a first reinforcing portion, the first reinforcing portion being a thickened layer; a portion of the side wall of the carrier grid has a reinforcing portion, the reinforcing portion of the side wall of the carrier grid being a second reinforcing portion, the second reinforcing portion being a reinforcing rib;

[0016] The first reinforcing part is connected to the second reinforcing part.

[0017] The first reinforcing part is located around the bottom wall of the carrier grid, and the second reinforcing part is located at the junction of the side walls of two adjacent carrier grids. This arrangement can effectively increase the strength of the side walls and bottom walls of the carrier grid, while using less material and increasing the weight slightly. The first reinforcing part is connected to the second reinforcing part, which can make the overall strength of the carrier grid stronger and effectively reduce the risk of deformation of electronic components in the carrier tape body.

[0018] In one embodiment of the present invention, one end of the second reinforcing part extends to the strip.

[0019] In one embodiment of the present invention, the strip body is provided with a plurality of transmission holes spaced apart along its length.

[0020] In practical applications, the transmission hole can be a circular hole or a regular polygonal hole.

[0021] In one embodiment of the present invention, the carrier tape cavity has a limiting step, which is used to cooperate with electronic components to limit the distance at which the electronic components are placed in the carrier tape cavity.

[0022] In one embodiment of the present invention, the bottom of the carrier tape cavity has a separating protrusion, and the electronic component has multiple sets of pins. After the electronic component is installed, the separating protrusion is located between two adjacent sets of pins.

[0023] The separation protrusions allow for the separation of different groups of pins, ensuring the overall reliability of electronic components.

[0024] In practical applications, the carrier tape body can be made of various materials, such as polycarbonate. Polycarbonate is a high molecular polymer containing carbonate groups in its molecular chain. Polycarbonate has advantages such as high mechanical strength, good transparency, dimensional stability, and good heat resistance, which effectively improves the service life of the carrier tape body.

[0025] In one embodiment of this utility model, the area ratio of the first reinforcing part to the bottom wall of the carrier grid is 20% to 80%, preferably 20% to 45%.

[0026] In one embodiment of the present invention, the ratio of the thickness of the second reinforcing part to the thickness of the sidewall of the carrier grid is 0.8 to 2.

[0027] In one embodiment of this utility model, the sidewalls of the carrier grid are inclined, and the angle between the sidewalls of the carrier grid and the bottom wall of the carrier grid is greater than 90°.

[0028] The sidewalls of the carrier grid are inclined to facilitate the demolding operation during the embossing process.

[0029] This application also discloses an embossed carrier tape, including the carrier tape body of the embossed carrier tape described above, and a cover tape, which is used to fix the carrier tape body and close the carrier cavities of the carrier grid.

[0030] In one embodiment of this utility model, the cover strip is a transparent cover strip.

[0031] The transparent cover allows for direct observation of the status of electronic components located inside the carrier tape cavity.

[0032] In one embodiment of this utility model, the cover strip is a light-shielding cover strip.

[0033] In one embodiment of the present invention, the carrier body has a concave-convex structure around the carrier grid, and the cover tape is hot-pressed to the concave-convex structure.

[0034] The concave-convex structure increases the connection area, thereby making the carrier tape body and the cover tape more tightly bonded.

[0035] In one embodiment of the present invention, one side of the cover strip has an adhesive tape, which is a thermoplastic elastomer and cooperates with the concave-convex structure.

[0036] The adhesive tape effectively ensures a reliable and tight connection between the cover tape and the concave-convex structure. During actual processing, the adhesive tape melts and deforms when heated, embedding itself into the concave-convex structure. After cooling, the two are reliably bonded together.

[0037] The strong bond between the cover tape and the carrier tape body reduces the risk of electronic components being contaminated, deformed, or damaged due to poor sealing, effectively ensuring the quality of electronic components.

[0038] In one embodiment of the present invention, the surface of the strip has a strip-shaped notch, and the area where the strip-shaped notch is located completely covers the opening end of each carrier grid.

[0039] The strip-shaped notch can be used for positioning and limiting when the cover strip and the strip body are heated and combined, ensuring that the position of the cover strip is reliable and stable.

[0040] In one embodiment of this utility model, the width of the strip notch is equal to the width of the cover strip.

[0041] In one embodiment of this utility model, the width of the strip-shaped notch is slightly larger than the width of the cover strip. In practical applications, the width of the strip-shaped notch can be 0.2mm to 2mm larger than the width of the cover strip.

[0042] The beneficial effects of this utility model are as follows: By setting reinforcing parts in the local structure, the strength of the carrier tape body is increased, the risk of carrier tape body deformation is reduced, and the risk of damage to electronic components is minimized. Furthermore, compared to increasing the overall thickness of the carrier tape body to improve its strength, the locally set reinforcing parts reduce material usage, lower material costs, and reduce the weight of the entire roll of embossed carrier tape.

[0063] like Figure 1 and 7 As shown, an embossed carrier tape is disclosed, including a carrier tape body 1 and a cover tape 3.

[0064] like Figure 1 , 2 As shown in Figures 3 and 6, the carrier body 1 includes a strip 11 and a plurality of carrier grids 12 spaced apart along the length of the strip 11. Each carrier grid 12 has a carrier cavity 121 for accommodating electronic components 2. Parts of the bottom wall and side walls of the carrier grid 12 have reinforcing portions. Specifically, the reinforcing portion of the bottom wall of the carrier grid 12 is a first reinforcing portion 122, which is a thickened layer; the reinforcing portion of the side walls of the carrier grid 12 is a second reinforcing portion 123, which is a reinforcing rib.

[0065] The carrier body 1 of this application has reinforcements provided locally on the bottom and side walls of the carrier grid 12, relative to... Figure 4 and Figure 5 Without reinforcement, the strength of the carrier tape body 1 is increased, reducing the risk of deformation and minimizing the risk of damage to electronic components 2. Furthermore, compared to increasing the overall thickness to improve the strength of the carrier tape body 1, locally adding reinforcement reduces material usage, lowers material costs, and reduces the weight of the entire roll of embossed carrier tape.

[0066] In some embodiments, the reinforcement may be provided only on the bottom wall or the side wall of the carrier grid 12.

[0067] like Figure 2 and Figure 3 As shown, in some embodiments, the first reinforcing part 122 is disposed around the bottom wall of the carrier grid 12.

[0068] The first reinforcing part 122 is arranged around the bottom wall of the carrier grid 12. This arrangement can effectively increase the bottom strength of the carrier grid 12, while using less material and increasing the weight less.

[0069] like Figure 2 and Figure 3As shown, the bottom wall of the carrier grid 12 has four sides, and the first reinforcing part 122 is disposed on the four sides of the bottom wall of the carrier grid 12.

[0070] like Figure 2 and Figure 3 As shown, in some embodiments, the second reinforcement 123 is located at the junction of the sidewalls of two adjacent carrier grids 12.

[0071] The second reinforcing part 123 is located at the junction of the side walls of two adjacent carrier grids 12. This arrangement can effectively increase the strength of the side walls of the carrier grids 12, and requires less material and results in less weight increase.

[0072] In some embodiments, the second reinforcement 123 is located on the outer side of the sidewall of the carrier grid 12.

[0073] In some embodiments, the second reinforcement 123 is located inside the sidewall of the carrier grid 12.

[0074] like Figure 2 and 3 As shown, in some embodiments, the first reinforcing part 122 is connected to the second reinforcing part 123. The connection between the first reinforcing part 122 and the second reinforcing part 123 makes the overall strength of the carrier grid 12 stronger and effectively reduces the risk of deformation of the electronic components 2 within the carrier body 1.

[0075] like Figure 2 and 3 As shown, in some embodiments, one end of the second reinforcing portion 123 extends to the strip 11.

[0076] In some embodiments, the first reinforcing part 122 occupies 20% to 80% of the area of ​​the bottom wall of the carrier grid 12.

[0077] In some embodiments, the thickness of the second reinforcing part 123 is 0.8 to 2 times the thickness of the sidewall of the carrier grid 12.

[0078] like Figure 2 As shown, in some embodiments, the sidewalls of the carrier grid 12 are inclined, and the angle between the sidewalls of the carrier grid 12 and the bottom wall of the carrier grid 12 is greater than 90°. The inclined sidewalls of the carrier grid 12 facilitate the demolding operation during the embossing carrier tape processing.

[0079] like Figure 1 As shown, in some embodiments, the strip 11 is provided with a plurality of transmission holes 111 spaced apart along its length. In practical applications, the transmission holes 111 can be circular holes or regular polygonal holes.

[0080] like Figure 2As shown, in some embodiments, the carrier tape cavity 121 has a limiting step 1211, which is used to cooperate with the electronic component 2 to limit the distance of the electronic component 2 placed in the carrier tape cavity 121.

[0081] like Figure 2 and 3 As shown, in some embodiments, the bottom of the carrier tape cavity 121 has a separating protrusion 1212, and the electronic component 2 has multiple sets of pins 21. After the electronic component 2 is installed, the separating protrusion 1212 is located between two adjacent sets of pins 21. The separating protrusion 1212 can separate each set of pins 21, ensuring the overall reliability of the electronic component 2.

[0082] In practical applications, the carrier tape body 1 can be made of various materials, such as polycarbonate. Polycarbonate is a high molecular polymer containing carbonate groups in its molecular chain. Polycarbonate has the advantages of high mechanical strength, good transparency, dimensional stability and heat resistance, which effectively improves the service life of the carrier tape body 1.

[0083] like Figure 6 and 7 As shown, the cover tape 3 is used to fix the carrier tape body 1 and close the carrier tape cavity 121 of the carrier grid 12, thereby enclosing the electronic components 2 in the carrier tape cavity 121.

[0084] In some embodiments, the cover strip 3 is a transparent cover strip 3. The transparent cover strip 3 facilitates direct observation of the state of the electronic components 2 located in the carrier cavity 121.

[0085] Due to confidentiality requirements, in some embodiments, the cover strip 3 is a light-shielding cover strip 3.

[0086] like Figure 8 As shown, in some embodiments, the carrier tape body 1 has a concave-convex structure 112 around the carrier grid 12, and the cover tape 3 is hot-pressed to the concave-convex structure 112. The concave-convex structure 112 can increase the connection area, thereby making the carrier tape body 1 and the cover tape 3 more tightly bonded.

[0087] In some embodiments, one side of the cover strip 3 has an adhesive tape 31, which is a thermoplastic elastomer. The adhesive tape 31 mates with the concave-convex structure 112. The adhesive tape effectively ensures a reliable and tight connection between the cover strip and the concave-convex structure. During actual processing, the adhesive tape melts and deforms upon heating, embedding itself into the concave-convex structure. After cooling, the two reliably bond together. The strong bond between the cover strip 3 and the carrier tape body 1 reduces the risk of electronic components being contaminated, deformed, or damaged due to poor sealing, effectively ensuring the quality of the electronic components.

[0088] In some embodiments, such as Figure 10As shown, the surface of the strip 11 has a strip-shaped notch 13, and the area where the strip-shaped notch is located completely covers the opening end of each carrier grid 12. The width of the strip-shaped notch 13 is equal to or slightly greater than the width of the cover strip 3.

[0089] The strip-shaped notch 13 can play a positioning and limiting role when the cover strip 3 and the strip body 11 are heated and combined, ensuring that the position of the cover strip 3 is reliable and stable.

[0090] In some embodiments, the width of the strip notch 13 may be 0.2 mm to 2 mm larger than the width of the cover strip 3.

[0091] It should be noted that, where there is no conflict, the features in the different embodiments of this application described above can be combined with each other. Furthermore, in each of the above embodiments, the focus is on describing the differences from other embodiments; other specific descriptions of the same / similar parts between the embodiments can be referred to (or referenced) interchangeably.
