Technical Field

[0001] The utility model relates to an SMT patch carrier tape and belongs to the technical field of SMT patches. Background Art

[0002] SMT patch refers to the abbreviation of a series of process flows based on PCB processing. It generally refers to surface assembly technology and is the most popular technology and process in the electronic assembly industry. Carrier tape generally refers to plastic carriers widely used in the packaging of SMT electronic components such as ICs, resistors, inductors, capacitors, connectors, fuses, switches, relays, connectors, oscillators, diodes, transistors, etc.

[0003] When the existing traditional SMT patch carrier tape is used, the SMT patch is generally loaded first and then rolled onto the carrier tape reel. The current carrier tape structure is relatively simple, and usually a carrying groove is opened on the carrying surface. However, when the SMT patch is carried, it is easy to shake during the rolling process, which will cause the SMT patch in the carrying groove to shake and sometimes fall off, thereby damaging the SMT patch. Secondly, there is a certain gap between the carrier tapes during rolling, which will cause contamination to the SMT patch, reduce the performance of the carrier tape in protecting the SMT patch, and reduce the practicability of the carrier tape. Utility Model Content

Secondly, the SMT patch carrying area can be sealed after the carrier tape is rolled up to prevent dust from falling on the SMT patch, thereby improving the practicability of the carrier tape.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: an SMT patch carrier, including a carrier body, a bearing groove is provided on the upper surface of the carrier body, and a slide groove is provided on the inner surface of the bearing groove, a buckle block is slidably connected to the inside of the slide groove, and one end of the buckle block is fixedly connected to a spring, one end of the spring is fixedly connected to the inside of the slide groove, and a limit assembly is provided above the spring, sealing grooves are provided on both sides of the bearing groove, and sealing strips are symmetrically fixedly connected to the lower surface of the carrier body, and the sealing strips are aligned with the sealing grooves on the upper surface of the carrier body.

[0006] Preferably, the other end of the buckling block is provided with an inclined surface, and one end of the buckling block is a triangular structure.

[0007] Preferably, the limit assembly includes a limit groove, and the limit groove is located at the top of the slide groove, the limit groove is internally slidably connected to a limit block, and a connecting plate is fixedly connected to one side surface of the limit block, and one end of the connecting plate is fixedly connected to one end of the buckle block.

[0008] Preferably, a sponge pad is fixedly connected to the lower surface of the carrier body, and the sponge pad and the bearing groove are aligned with each other.

[0009] Preferably, the bottom of the sealing strip is an arc-shaped structure.

[0010] The beneficial effects of the utility model are as follows: the utility model can increase the stability of the SMT patches when the carrier tape carries the SMT patches, avoid shaking or detachment of the SMT patches when the carrier tape is rolled up, and prevent damage to the SMT patches; secondly, the SMT patch carrying area can be sealed after the carrier tape is rolled up to prevent dust from falling on the SMT patches, thereby improving the practicability of the carrier tape.

[0017] As a technical optimization solution of the utility model, the other end of the buckle block 4 is provided with an inclined surface, and one end of the buckle block 4 is a triangular structure, so it is convenient to place and remove the SMT patch.

[0018] As a technical optimization solution of the utility model, the limit assembly includes a limit groove 9, and the limit groove 9 is located at the top of the slide groove 7, the internal sliding connection of the limit groove 9 is connected to the limit block 11, and a connecting plate 10 is fixedly connected to the surface of one side of the limit block 11, and one end of the connecting plate 10 is fixedly connected to one end of the buckle block 4, which can limit the buckle block 4 to prevent the buckle block 4 from sliding during the process of storing the roll carrier body 1, thereby causing the SMT patch to be unstable.

[0019] As a technical optimization solution of the utility model, a sponge pad 6 is fixedly connected to the lower surface of the carrier body 1, and the sponge pad 6 is aligned with the carrying slot 2, so that the sponge pad 6 can be embedded in the interior of the carrying slot 2 after winding, thereby further protecting the SMT patch, thereby improving the safety of the SMT patch in the carrier body 1.

[0021] When the utility model is in use, the SMT patch is first placed on the inner side of the carrying slot 2, and then the worker slightly presses the SMT patch, and at the same time the SMT patch will squeeze the buckle block 4, and at this time the buckle block 4 will shrink to the inside of the slide slot 7, and when the SMT patch falls under the buckle block 4, the buckle block 4 will be ejected by the elastic force of the spring 8, so that the buckle block 4 is against the upper surface of the SMT patch, and when the carrier body 1 is rolled up, the sealing strip 5 on the lower surface of the carrier body 1 will be embedded in the sealing groove 3 on the upper surface of the carrier body 1 after the carrier body 1 is wound around once, thereby sealing the SMT patch inside the carrying slot 2 to prevent dust from entering the inside of the carrying slot 2.
