Description

Technical Field

[0001] This utility model relates to the field of antistatic tape technology, and in particular to an antistatic polyimide tape. Background Technology

[0002] Antistatic tape is a special type of tape that has been treated with a special antistatic process to give it antistatic properties. It can reduce the generation of static electricity in the manufacturing industry and help eliminate the problem of static electricity. The roll of antistatic tape is light yellow, but it is completely transparent when pulled open, making it easy to see the items being pasted. It can be used to paste static-sensitive devices, seal packaging bags, and package other electronic products.

[0003] When performing anti-static bonding, especially when bonding static-sensitive devices, workers usually touch the ground or other grounded conductive parts with their hands first to release static electricity from their bodies before proceeding with the above operations. However, in actual use, friction from clothing and other factors can easily cause residual static electricity to remain after the bonding process. If a worker accidentally touches a static-sensitive device, it can easily be damaged. If workers wear anti-static gloves, the gloves reduce direct contact with the adhesive and adhesion of the tape, making it difficult to accurately judge whether the tape is firmly adhered or whether there are air bubbles or wrinkles. It also reduces hand dexterity and precision. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an antistatic polyimide tape. This tape eliminates the need for antistatic gloves during application, simplifying the application process. Furthermore, the cut areas can be marked for easy reuse.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An antistatic polyimide tape includes a tape support ring and a tape body wound on the surface of the tape support ring; an antistatic release mechanism including a conductive metal ring through which the tape support ring passes, a wire connected to the rear side of the conductive metal ring, and a grounding electrode fixedly connected to the other end of the wire, the grounding electrode being made of conductive metal; and a marking mechanism for facilitating locating the cut point of the tape during future use.

[0007] Preferably, both the conductive metal ring and the grounding earth are made of copper-copper composite steel.

[0008] Preferably, the tape body is composed of an antistatic layer, a polyimide film substrate layer, and an adhesive layer.

[0009] Preferably, the antistatic layer is located on the outer side, the polyimide film substrate layer is located in the middle, and the adhesive layer is located on the inner side.

[0010] Preferably, the marking mechanism includes a rectangular guide rod that passes through the conductive metal ring, with an arc-shaped extrusion plate fixedly connected to the upper end of the guide rod, and the lower end of the guide rod being elastically connected to the inner bottom of the conductive metal ring via a spring.

[0011] Preferably, the lower end of the guide rod is fixedly connected to a rotating shaft, the lower end of the rotating shaft is rotatably connected to a rotating bar, and the lower end of the conductive metal ring is fixedly connected to a support plate that cooperates with the rotating bar.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. Through the designed conductive metal ball and conductive metal ring structure, users can effectively release static electricity from their human body to the ground through the wire without wearing anti-static gloves when using tape. This greatly simplifies the operation process, avoids the inconvenience caused by wearing additional protective equipment, and thus improves work efficiency.

[0014] 2. After each tape cut, the cut position can be easily marked, which facilitates the next use and improves the overall convenience and efficiency of use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 An antistatic polyimide tape includes a tape support ring 1 and a tape body 2 rolled on the surface of the tape support ring 1. The tape body 2 is composed of an antistatic layer 21, a polyimide film substrate layer 22 and an adhesive layer 23. The antistatic layer 21 is located on the outer side, the polyimide film substrate layer 22 is located in the middle, and the adhesive layer 23 is located on the inner side.

[0021] It also includes an electrostatic discharge mechanism, which includes a conductive metal ring 3, a tape support ring 1 passing through the conductive metal ring 3, a wire 4 connected to the rear side of the conductive metal ring 3, and a grounding 5 fixedly connected to the other end of the wire 4. The grounding 5 is made of conductive metal, and both the conductive metal ring 3 and the grounding 5 are made of copper composite steel.

[0022] It also includes a marking mechanism, which is used to facilitate finding the cut point of the tape during the next use. The marking mechanism includes a rectangular guide rod 7 that passes through the conductive metal ring 3. The upper end of the guide rod 7 is fixedly connected to an arc-shaped extrusion plate 6. The lower end of the guide rod 7 is elastically connected to the inner bottom of the conductive metal ring 3 by a spring 10. The lower end of the guide rod 7 is fixedly connected to a rotating shaft. The lower end of the rotating shaft is rotatably connected to a rotating bar 9. The lower end of the conductive metal ring 3 is fixedly connected to a support plate 8 that cooperates with the rotating bar 9.

[0023] In this utility model, when in use, the operator first places the ground contact 5 on the ground, then pulls the rotating bar 9 down, and after the height of the upper end of the rotating bar 9 is lower than the height of the support plate 8, the rotating bar 9 is twisted to rotate, and then the rotating bar 9 is released. Under the elastic action of the spring 10, the rotating bar 9 and the guide rod 7 move back. However, because the return of the rotating bar 9 is blocked by the support plate 8 at this time, it cannot move back, but the spring 10 is still in a compressed state.

[0024] This is the tape body 2 that the user can use normally. When using it, the user's hands are always in contact with the tape support ring 1, and all the static electricity on the user's body is released to the ground along the tape support ring 1, conductive metal ring 3, wire 4 and grounding 5, ensuring the elimination of static electricity. There is no need to wear static gloves, which makes the actual operation convenient.

[0025] In addition, after each application and cut of the tape, the conductive metal ring 3 can be rotated (to align the arc-shaped extrusion plate 6 with the cut), and then the rotating bar 9 can be twisted back to the initial state. Under the elastic action of the spring 10, the arc-shaped extrusion plate 6 will press against the cut, achieving the purpose of marking and making it convenient to find the cut in the next use.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
