With the rapid development of 5G networks, consumer electronics, automotive electronics, smart healthcare, security monitoring, smart homes, and other fields, the market demand for electronic components has increased dramatically, and with it, the demand for plastic carrier tape. Plastic carrier tape is not only used for the storage and transportation of electronic components in these products, but also plays a key role in the packaging production process, directly affecting the performance and reliability of electronic component packaging.

[0003] Existing plastic carriers are usually made of thermoplastic plastics. The manufacturing processes of plastic carriers mainly include extrusion molding, stretch molding and meltblowing molding, among which extrusion molding is the most common process. The basic structure of the plastic carrier includes the carrier body, as well as holes, grooves and other structures that may be designed as needed to facilitate the fixation and positioning of electronic components.

[0004] However, although the existing plastic carriers perform well in many aspects, there are still some defects. With the increase in the size and weight of electronic components, higher requirements are placed on the load-bearing and limiting capacity of plastic carriers. Some existing carriers may deform or break when carrying heavier components, and the existing plastic carriers have poor stability for the mounting of electronic components, which makes them easy to loosen and shake in holes or grooves, thereby affecting the safety of transportation and packaging. At the same time, the existing plastic carriers have insufficient anti-static performance, which makes the carriers subject to friction when winding or unfolding, which easily leads to adhesion and adsorption of dust in the air, affecting use.

[0006] The purpose of this utility model is achieved by the following methods:

[0007] A thermoplastic plastic carrier tape comprises a tape body, on which a plurality of bearing grooves for placing electronic components are integrally formed by hot pressing.

A raised pressing protrusion is formed on the bottom of the tape body, and a pressing groove corresponding to the number and position of the positioning ribs is provided on the pressing protrusion, so that the pressing protrusion of the tape body can be pressed with a corresponding bearing groove, thereby sealing the bearing groove. The bottom of the pressing protrusion is provided with an installation groove, and a conductive strip is embedded in the installation groove.

[0008] Further in the above description, the upper surface of the belt body is provided with a plurality of tensioning positioning holes, one end of the tensioning positioning hole is provided with a notch, the upper surface of the belt body is bonded with a detachable sealed film belt, and the surface of the sealed film belt is formed with a positioning column that is matched with the tensioning positioning hole.

[0009] By setting tensioning positioning holes distributed on the edge of the load-bearing groove, the sealed film belt can be plugged and installed with the corresponding tensioning positioning holes through the positioning columns, further enhancing the tensioning and sealing of the sealed film belt on the notch of the load-bearing groove, thereby preventing the sealed film belt from bulging and warping, and further enhancing the stability of load-bearing use.

[0010] Further in the above description, a positioning groove is provided on the upper surface of the belt body, and a positioning protrusion that matches the positioning groove is formed on the surface of the sealed film belt.

[0013] The traction positioning holes are provided to facilitate positioning and transportation with the external material tray.

[0014] Furthermore, in the above description, a conductive pressure relief hole is provided inside the bearing groove, which can prevent the negative pressure generated on the inner wall of the bearing groove from squeezing the electronic components.

[0015] The beneficial effects of the present invention are as follows: the raised positioning ribs arranged on the inner wall of the bearing groove can accurately position and fix the electronic components placed in the groove, preventing them from shifting or being damaged during transportation or use, providing stable support and protection for the electronic components, and enhancing the firmness and durability of the overall structure of the bearing groove. The design of the pressing protrusion and the pressing groove thereon enables the pressing protrusion and the bearing groove to be accurately aligned and pressed when the belt body is wound, thereby pressing and sealing the bearing groove, reducing the loosening of electronic components inside the bearing groove and the entry of dust, and arranging the conductive wire and the conductive strip to be embedded in the corresponding embedding groove and installation groove, thereby avoiding the accumulation of electric charges at the edge of the plastic carrier, so that the carrier has anti-static properties and improves the use effect.

DETAILED DESCRIPTION

[0022] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0023] In this embodiment, refer to Figure 1-Figure 5The present invention relates to a thermoplastic plastic carrier tape, comprising a tape body 1, on which a bearing groove 2 for placing electronic components is integrally formed by hot pressing. The bearing groove 2 is evenly spaced along the length direction of the tape body 1, and the inner wall of the bearing groove 2 is formed with four raised positioning ribs 3 by hot pressing. The positioning ribs 3 are distributed on the inner wall of the bearing groove 2 in pairs. Four positioning ribs 3 are formed inside each bearing groove 2, and an embedding groove 4 is provided on the surface of the tape body 1. The embedding groove 4 is distributed around the outside of the bearing groove 2, and a conductive wire 5 is embedded in the embedding groove 4. A raised pressing protrusion 6 is formed on the bottom of the tape body 1, and a pressing groove 7 corresponding to the number and position of the positioning ribs 3 is provided on the pressing protrusion 6, so that the pressing protrusion 6 of the tape body 1 can be pressed with a corresponding bearing groove 2, thereby sealing the bearing groove 2. The bottom of the pressing protrusion 6 is provided with a mounting groove 8, and a conductive strip 9 is embedded in the mounting groove 8.

[0024] The upper surface of the belt body 1 is provided with a tensioning hole 10, one end of which is notched. A removable sealing film strip 16 is bonded to the upper surface of the belt body 1. Positioning posts 11 are formed on the surface of the sealing film strip 16 to mate with the tensioning hole 10. Positioning grooves 12 are formed on the upper surface of the belt body 1, and positioning protrusions 13 are formed on the surface of the sealing film strip 16 to mate with the positioning grooves 12. The tensioning holes 10 are distributed along the edges of the bearing groove 2, allowing the sealing film strip 16 to be inserted and installed with the corresponding tensioning holes 10 via the positioning posts 11. This further strengthens the tensioning seal of the sealing film strip 16 against the notch of the bearing groove 2, preventing it from bulging and warping, and enhancing stability during use. The positioning protrusions 13 further secure the sealing film strip 16 in place within the positioning grooves 12 of the belt body 1, further enhancing the seal of the sealing film strip 16 within the bearing groove 2 of the belt body 1.

[0025] The edge of the belt body 1 is provided with conductive traction positioning holes 14, distributed in an array along the length of the belt body 1. These holes facilitate positioning and transport of the external material tray. The interior of the support groove 2 is provided with conductive pressure relief holes 15.

The positioning grooves 12 provided on the belt body 1 allow the positioning protrusions 13 of the sealed film belt 16 to be matched and installed, and the positioning columns 11 on the sealed film belt 16 are plugged into the tensioning positioning holes 10 on the edge of the bearing groove 2, so that the sealed film belt 1 6 is tightly fitted on the belt body 1, and the design of the pressing protrusion 6 and the pressing groove 7 thereon enables the belt body 1 to accurately align its pressing protrusion 6 with the bearing groove 2 when it is wound and press the sealed film belt 16, so that the bearing groove 2 can be pressed and sealed, reducing the loosening of electronic components inside the bearing groove 2 and the entry of dust. The conductive wire 5 and the conductive strip 9 are embedded in the corresponding embedding groove 4 and the installation groove 8, so that the carrier tape can avoid the electric charge from gathering at the edge of the plastic carrier tape when it is wound or stretched for transportation, thereby making the carrier tape anti-static and improving the use effect.
