Description

Technical Field

[0001] The utility model relates to the technical field of cover tapes, in particular to a self-adhesive upper cover tape. Background Technique

[0002] Generally, for the packaging of electronic components (such as resistors, capacitors, transistors, etc.), carrier tapes are used for loading. Multiple electronic component slots are provided on the carrier tape. The corresponding electronic components are placed in the electronic component slots of the carrier tape, and a self-adhesive upper cover is attached to the carrier tape, covering above the electronic component slots, covering the electronic component slots to form a closed storage slot to protect the electronic components from being contaminated during transportation, and finally the carrier tape is wound and collected.

[0003] The prior art patent document with the publication number CN218143296U provides a self-adhesive upper cover tape, which includes two layers of plastic films and a colloid layer. The colloid layer is located between the two layers of plastic films to bond the two layers of plastic films. The width of the lower plastic film is smaller than that of the upper plastic film. Both sides of the colloid layer extend downward towards the lower plastic film to form side colloid layers, and the side colloid layers are located on both sides of the lower plastic film; it also discloses a carrier tape, including a carrier tape body, on which a row of electronic component slots for storing electronic components are provided, and the above self-adhesive upper cover tape is pasted above each row of electronic component slots; it also discloses a carrier tape including the aforementioned self-adhesive upper cover tape. The utility model has the advantages of being able to reduce the overall thickness of the self-adhesive upper cover tape, reduce the amount of colloid used, low production cost, no colloid overflow, and compared with the traditional self-adhesive upper cover tape, only a very small pressing force is required during use to seal the carrier tape.

[0004] However, during the use of the existing self-adhesive upper cover tape, since the cover tape needs to be pasted on the carrier tape, and during the pasting process, due to the temperature of the air and the heat resistance of the colloid layer itself, there will also be certain differences in viscosity. The viscosity is lower in winter than in summer, resulting in the problem that the cover tape is not firmly bonded. For this reason, we propose a self-adhesive upper cover tape. Content of the Utility Model

[0005] (I) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides a self-adhesive upper cover tape to solve the problems raised in the above background technique.

[0007] (II) Technical Solutions

[0008] To achieve the above objectives, the utility model is realized through the following technical solutions: a self-adhesive upper cover tape, including a cover tape body, a bonding layer is fixedly connected to the bottom of the cover tape body, the bonding layer includes a high-temperature resistant adhesive, a hot melt adhesive and a low-temperature resistant adhesive, the high-temperature resistant adhesive is fixedly connected to both sides of the bottom of the bonding layer, a hot melt adhesive is fixedly connected to one side of the high-temperature resistant adhesive, and a low-temperature resistant adhesive is fixedly connected to one side of the hot melt adhesive, an anti-static layer is fixedly connected to the top of the cover tape body, a polyester film layer is fixedly connected to the bottom of the anti-static layer, a base material layer is fixedly connected to the top of the polyester film layer, an intermediate layer is fixedly connected to the bottom of the base material layer, and a PET layer is fixedly connected to the bottom of the intermediate layer.

[0010] Preferably, there are two high-temperature resistant adhesives, hot melt adhesives and low-temperature resistant adhesives respectively, and the lengths of the two high-temperature resistant adhesives, hot melt adhesives and low-temperature resistant adhesives are the same.

[0011] Preferably, the thickness of the bonding layer is 0.01 to 0.03 millimeters.

[0012] Preferably, the base material layer is made of PE material, and the thickness of the base material layer is 0.02 to 0.03 millimeters.

[0013] Preferably, the cover tape body is of a transparent structure, and the outer surface of the cover tape body is smooth.

[0014] (III) Beneficial effects

[0015] The utility model provides a self-adhesive upper cover tape, which has the following beneficial effects:

[0016] (1). For this self-adhesive upper cover tape, through the arranged bonding layer, high-temperature resistant adhesive, hot melt adhesive and low-temperature resistant adhesive, when using the self-adhesive upper cover tape, the staff installs the device in the groove of the carrier tape, and then places the cover tape body on the carrier tape. At this time, the high-temperature resistant adhesive and the low-temperature resistant adhesive on the bonding layer will self-adhere to the carrier tape. Because the high-temperature resistant adhesive and the low-temperature resistant adhesive have different viscosities at different temperatures, and the high-temperature resistant adhesive has a lower viscosity at low temperatures, the low-temperature resistant adhesive can be used to bond to the carrier tape, while the low-temperature resistant adhesive has a low viscosity at high temperatures, and the viscosity of the high-temperature resistant adhesive can be used to bond to the carrier tape. In some special cases, the cover tape body can be bonded to the carrier tape by heating the hot melt adhesive. In this way, the bonding method of the self-adhesive upper cover tape is improved, so that the self-adhesive upper cover tape can firmly bond to the carrier tape at different temperatures, making the bonding between the cover tape and the carrier tape more firm.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a self-adhesive upper cover tape, including a cover tape body 1, a bonding layer 2 is fixedly connected to the bottom of the cover tape body 1, the bonding layer 2 includes a high-temperature resistant glue 3, a hot melt glue 4 and a low-temperature resistant glue 5, the high-temperature resistant glue 3 is fixedly connected to both sides of the bottom of the bonding layer 2, a hot melt glue 4 is fixedly connected to one side of the high-temperature resistant glue 3, and a low-temperature resistant glue 5 is fixedly connected to one side of the hot melt glue 4. An antistatic layer 6 is fixedly connected to the top of the cover tape body 1, a polyester film layer 7 is fixedly connected to the bottom of the antistatic layer 6, a substrate layer 8 is fixedly connected to the top of the polyester film layer 7, an intermediate layer 9 is fixedly connected to the bottom of the substrate layer 8, and a PET layer 10 is fixedly connected to the bottom of the intermediate layer 9.

[0024] In this embodiment, specifically, a polycarbonate layer 11 is fixedly connected to the bottom of the PET layer 10, and the polycarbonate layer 11 is fixedly connected to the bonding layer 2. The PET layer 10 enables the cover tape to have an insulating function.

[0025] In this embodiment, specifically, two high-temperature resistant glues 3, hot melt glues 4 and low-temperature resistant glues 5 are provided, and the lengths of the two high-temperature resistant glues 3, hot melt glues 4 and low-temperature resistant glues 5 are the same. Since the high-temperature resistant glue 3 and the low-temperature resistant glue 5 have different viscosities at different temperatures, and the high-temperature resistant glue 3 has a low viscosity at low temperatures, the low-temperature resistant glue 5 can be used to bond to the carrier tape, while the low-temperature resistant glue 5 has a low viscosity at high temperatures, and the viscosity of the high-temperature resistant glue 3 can be used to bond to the carrier tape.

[0026] In this embodiment, specifically, the thickness of the adhesive layer 2 is 0.01 to 0.03 millimeters. The adhesive method of the self-adhesive upper cover tape is improved through the adhesive layer 2, enabling the self-adhesive upper cover tape to firmly adhere to the carrier tape at different temperatures.

[0027] In this embodiment, specifically, the base material layer 8 is processed from PE material, and the thickness of the base material layer 8 is 0.02 to 0.03 millimeters. The base material layer 8 processed from PE material is more durable and not easily damaged.

[0028] In this embodiment, specifically, the cover tape main body 1 has a transparent structure, and the outer surface of the cover tape main body 1 is smooth, enabling the staff to see the devices on the carrier tape through the cover tape main body 1.

[0029] Working principle: After the present utility model is installed, first check the installation, fixation and safety protection of the present utility model. When using the self-adhesive upper cover tape, the staff installs the device in the embedding groove of the carrier tape, and then places the cover tape main body 1 on the carrier tape. At this time, the high-temperature resistant adhesive 3 and the low-temperature resistant adhesive 5 on the adhesive layer 2 will self-adhere to the carrier tape. Because the high-temperature resistant adhesive 3 and the low-temperature resistant adhesive 5 have different viscosities at different temperatures, and the viscosity of the high-temperature resistant adhesive 3 is lower at low temperatures, the low-temperature resistant adhesive 5 can be used to adhere to the carrier tape. While the viscosity of the low-temperature resistant adhesive 5 is low at high temperatures, the viscosity of the high-temperature resistant adhesive 3 can be used to adhere to the carrier tape. In some special cases, the cover tape main body 1 can be adhered to the carrier tape by heating the hot melt adhesive 4. In this way, the use process of the present utility model is completed. The present utility model has a simple structure and is safe and convenient to use.
