[0002] Taping is a process that electronic components are accurately installed on the tape carrier according to the established rules and methods. In this process, the carrier tape plays a crucial role, especially as the main carrier of LED lamp pearl. The carrier tape is mainly applied to the electronic component mounting industry, and is used in cooperation with the cover tape (i.e. upper sealing tape) to carry and store resistors, capacitors, transistors, diodes and other electronic components in the pockets of the carrier tape, and to form a closed package by sealing the cover tape on the carrier tape to protect the electronic components from pollution and damage during transportation, thereby effectively ensuring the quality and performance of the electronic components. As a tape-shaped product designed for the electronic packaging field, the carrier tape has a specific thickness, and equidistantly distributed along the length direction of the carrier tape are the holes (also called pockets) for carrying electronic components and the positioning holes for indexing positioning. Figure 1 、 Figure 2 respectively are the front view and the top view of the ordinary carrier tape.

[0003] The mounting groove on the current LED carrier tape is a vertical upper body shape. In order to facilitate the placement and removal of the LED lamp pearl, the substrate of the LED lamp pearl is usually smaller than the inner diameter of the mounting groove, which causes the LED lamp pearl to be easily displaced in the mounting groove during placement or transportation. Especially when loading high ball cap LED lamp pearl, since the high ball cap LED lamp pearl has a large size in the height direction, the high ball cap LED lamp pearl is more likely to be displaced or even tilted in the mounting groove (as shown in Figure 3 When removing the LED lamp pearl, the placement machine cannot accurately suck up the LED lamp pearl, or even if the LED lamp pearl is sucked up, a long time is spent, which ultimately leads to the waste of LED lamp pearl and low placement efficiency. At the same time, the ordinary carrier tape has low strength due to the shape problem and has no anti-extrusion ability, and the LED lamp pearl on the carrier tape will be damaged due to extrusion during transportation. SUMMARY

[0004] The main technical problem to be solved by the utility model is to provide a special carrier tape for LED lamp pearl, which can avoid the displacement or even tilting of the LED lamp pearl in the mounting groove during placement of the LED lamp pearl (especially high ball cap LED lamp pearl and other high size LED lamp pearl) on the carrier tape or during transportation, so as to cause the low use rate and placement efficiency of the LED lamp pearl, and can also improve the situation that the ordinary carrier tape has low strength due to the shape problem and has no anti-extrusion ability, and the LED lamp pearl on the carrier tape will be damaged due to extrusion during transportation.

[0023] This invention utilizes a carrier tape with an arc-shaped structure on the inner wall of a frustum-shaped mounting groove with a large opening and a small bottom. This transforms the surface contact between the LED substrate and the inner wall of the groove into point contact, reducing friction and facilitating the insertion and removal of LED chips. This effectively improves the tape-making and mounting efficiency of LED chips. Furthermore, the arc-shaped structure restricts the displacement of LED chips, especially high-cap LED chips, preventing displacement or tilting within the mounting groove during placement or transportation. Additionally, a reinforcing rib is placed at the junction of two consecutive arc-shaped convex surfaces on the four walls of the mounting groove to enhance the strength of the carrier tape and improve its resistance to compression, effectively ensuring its quality and performance.

[0024] In some embodiments of the present application, the number of vacuum holes is equal to the number of the accommodation grooves.

[0025] In some embodiments of the present application, the vacuum holes are located at the center of the bottom of the accommodation grooves.

[0026] In some embodiments of the present application, the number of positioning holes is twice the number of the accommodation grooves and the vacuum holes, and the horizontal position of the positioning holes is tangent to the extension line of one side of the top surface of the accommodation grooves.

[0027] In some embodiments of the present application, the circular arc structures of the four inner walls of the accommodation grooves are completely the same.

[0028] In some embodiments of the present application, the cover tape covers the accommodation grooves, one side of the cover tape keeps a certain distance from the positioning holes without interference, and the other side of the cover tape coincides with the edge of the top surface of the carrier tape body.

[0029] In some embodiments of the present application, the material of the carrier tape body is plastic, and the material of the cover tape is transparent heat-sensitive plastic. Embodiment 1

[0030] Please refer to Figures 4-6 , the embodiment provides a special carrier tape for LED lamp beads, which comprises:

[0031] The carrier tape body 00 is used to provide a carrier body; Figure 4 As shown, a plurality of accommodation grooves 2 in a concave shape are arranged at one side edge of the top surface of the carrier tape body 00 and used to load LED lamp beads, a vacuum hole 3 is arranged at the center of the bottom of each accommodation groove 2, and the vacuum hole 3 can balance the air pressure, so that the LED lamp beads are more easily taken out. A plurality of positioning holes 1 arranged at uniform intervals are arranged at the other side edge of the top surface of the carrier tape body 00, the positioning holes 1 correspond to the accommodation grooves 2 in position, and are used to position the carrier tape body 00 on a taping machine or a chip mounter, so as to facilitate the machine to accurately put in or suck the LED lamp beads. The number of the positioning holes 1 is twice the number of the accommodation grooves 2 and the vacuum holes 3, and the horizontal position (longitudinal position of the carrier tape body) of the positioning holes 1 is tangent to the extension line of one side of the top surface of the accommodation grooves 2. The cover tape 01 is a cover film adhered to the carrier tape body 00 and used to seal the accommodation grooves 2. As shown, Figure 5 the other side of the cover tape 01 after sealing coincides with the edge of the top surface of the side of the carrier tape body 00 provided with the accommodation grooves 2. The material of the carrier tape body 00 is plastic, and the material of the cover tape 01 is transparent heat-sensitive plastic. The cover tape 01 is glued or heat-sealed to the carrier tape body 00.

[0032] It should be noted that, Figure 6As shown, the setting groove 2 presents a four-prism table shape with the upper large and the lower small, and the inner wall of the setting groove 2 is provided with a circular arc structure, that is, the inner surface 4 of each side wall of the four surrounding side walls of the setting groove is provided with two continuous convex circular arc structures, and the two circular arc structures on the same side are provided with a reinforcing rib 5. The four-prism table shape of the setting groove 2 with the upper large and the lower small is convenient for the LED lamp bead to be put in, and can also limit the displacement of the LED lamp bead, so that the chip mounter can accurately and quickly take out the LED lamp bead. Similarly, the circular arc structure of the inner surface 4 of the four surrounding side walls of the setting groove is also to limit the displacement of the LED lamp bead, and the reinforcing rib 5 between the two circular arc structures on the same side can improve the strength of the carrier tape and enhance the extrusion resistance of the carrier tape, so that the LED lamp bead in the setting groove 2 can be effectively protected when extrusion occurs during transportation.

Compared with the surface contact, the friction of the point contact is much smaller, which is more conducive to the putting in and taking out of the LED lamp bead, and can effectively improve the efficiency of the LED lamp bead and the efficiency of the chip mounter. The displacement of the LED lamp bead can also be limited, so that the LED lamp bead will not displace or even tilt in the setting groove during the placing or transporting process.
