Description

Technical Field

[0001] This utility model relates to the field of VHB double-sided adhesive, and in particular to an auxiliary mechanism for quick-tear backing paper of VHB double-sided adhesive. Background Technology

[0002] VHB double-sided tape is a high-performance double-sided tape. Due to its superior properties such as high strength and high adhesion, VHB double-sided tape is widely used in many fields, such as automobile manufacturing, electronic equipment assembly, and building decoration. When using VHB double-sided tape, the backing paper needs to be peeled off from the adhesive surface. However, due to the extremely strong adhesion of VHB double-sided tape, the backing paper is often tightly adhered to the adhesive surface.

[0003] Currently, in the process of assembling LCD modules in the field of electronic equipment assembly, VHB foam double-sided tape is required for the double-sided tape application process. Due to its high viscosity, the backing paper is difficult to peel off. Even with a backing paper peeler, it is still difficult to peel off. When pulling the peeler, the tape may even deform, affecting the assembly time of workers and thus reducing production efficiency. To address this issue, a quick-peel backing paper auxiliary mechanism for VHB double-sided tape is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick-peel backing paper auxiliary mechanism for VHB double-sided adhesive, which aims to improve the problem in the prior art that "VHB foam double-sided adhesive, due to its high viscosity, is difficult to peel off the backing paper, which will cause the adhesive to deform and thus reduce production efficiency".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-tear backing paper auxiliary mechanism for VHB double-sided adhesive, comprising an adhesive body, an upper backing paper disposed on the upper side of the adhesive body, a lower backing paper disposed on the lower side of the adhesive body, an auxiliary mechanism disposed on the outer side of the upper backing paper, the auxiliary mechanism comprising a separation component and an auxiliary component, the auxiliary component comprising a tear strip, the tear strip being fixedly connected to the front side of the upper backing paper, a first separation groove being formed through the upper backing paper near the left side of the tear strip, and a second separation groove being formed through the outer wall of the lower backing paper.

[0006] As a further description of the above technical solution:

[0007] The separation component includes a stop block, which is fixedly connected to the lower side of the bottom paper and is located on the right side near the second separation groove.

[0008] As a further description of the above technical solution:

[0009] The first separation groove is opened at an angle, and the opening angle between the first separation groove and the upper bottom paper is set to forty-five degrees.

[0010] As a further description of the above technical solution:

[0011] The second separation groove is opened at an angle, and the opening angle between the second separation groove and the bottom paper is set to 45 degrees.

[0012] As a further description of the above technical solution:

[0013] A protective component is provided on the upper side of the upper bottom paper. The protective component includes a shielding member, which is fixedly connected to the upper side of the upper bottom paper. The shielding member is located above the first separation groove. A fixing block is fixedly connected to the left side of the upper bottom paper near the first separation groove.

[0014] As a further description of the above technical solution:

[0015] The shielding member has a through hole on its left side, and the upper part of the fixing block is attached to the outside of the fixing block.

[0016] This utility model has the following beneficial effects:

[0017] 1.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a quick-tear backing paper auxiliary mechanism for VHB double-sided adhesive, comprising an adhesive 1, which is VHB foam double-sided adhesive with the advantage of high viscosity. An upper backing paper 2 is provided on the upper side of the adhesive 1, and a lower backing paper 3 is provided on the lower side of the adhesive 1. Before the VHB double-sided adhesive is used, the upper backing paper 2 and the lower backing paper 3 tightly cover the upper and lower surfaces of the adhesive 1, which plays a role in protecting the adhesiveness of the upper surface of the adhesive 1. An auxiliary mechanism is provided on the outside of the upper backing paper 2. The auxiliary mechanism includes a separation component and an auxiliary component. The auxiliary component includes a tear strip 41, which provides a convenient point of leverage for the user to easily peel off the upper backing paper 2. The tear strip 41 is fixedly connected to the front side of the upper backing paper 2. A separation groove 42 is provided through the upper backing paper 2 near the left side of the tear strip 41.

[0026] Furthermore, the first separation groove 42 is inclined, and the opening angle between the first separation groove 42 and the upper backing paper 2 is set to 45 degrees, creating a sharp angle. This allows the initial force for tearing the backing paper to be concentrated on the 45° sharp angle, facilitating initial opening. Then, as the tearing area gradually increases, the originally difficult-to-tear VHB foam double-sided adhesive backing paper can be easily torn apart. At the same time, the originally annular upper backing paper 2 becomes an annular strip, making it easier to peel off the upper backing paper 2. The outer wall of the lower backing paper 3 is provided with a second separation groove 43, which is inclined and the opening angle between the second separation groove 43 and the lower backing paper 3 is set to 45 degrees. The function of the second separation groove 43 is the same as that of the first separation groove 42, which facilitates the peeling off of the lower backing paper 3, avoids damage and deformation to the adhesive layer, improves quality, and ensures production efficiency.

[0027] Reference Figure 1 and Figure 2 The separation component includes a stop block 44, which is fixedly connected to the lower side of the bottom paper 3. The stop block 44 is located on the right side near the second separation groove 43. The stop block 44 is near the sharp corner of the bottom paper 3. When peeling off the bottom paper 3, the stop block 44 is squeezed to generate a radial force, which drives the bottom paper 3 to squeeze the colloid 1, thereby allowing the bottom paper 3 to detach. This facilitates the quick peeling off of the bottom paper 3. The stop block 44 can act as a barrier, increasing the resistance when peeling off the bottom paper 3, making the detachment process smoother.

[0028] Reference Figure 1 and Figure 3 A protective component is provided on the upper side of the upper base paper 2. The protective component includes a shielding member 51, which is fixedly connected to the upper side of the upper base paper 2. The shielding member 51 is positioned above the separation groove 42. During transportation or storage, it protects the sharp corners of the upper base paper 2, preventing the upper base paper 2 from detaching from the adhesive 1 and causing foreign matter to affect the adhesiveness of the adhesive 1. A fixing block 53 is fixedly connected to the left side of the upper base paper 2 near the separation groove 42 to fix the shielding member 51 vertically, thereby preventing the shielding member 51 from loosening. At the same time, it can fix the upper base paper 2 on both sides of the separation groove 42, increasing the stability of the upper base paper 2. A through hole 52 is opened on the left side of the shielding member 51. The upper part of the fixing block 53 is attached to the outside of the fixing block 53, providing installation space for the fixing block 53. At the same time, the shielding member 51 can easily pull the upper base paper 2.

[0029] Working principle: When using the adhesive 1 and peeling off the top paper 2, the operator can move the blocking part 51 to one side to disengage the through hole 52 from the fixing block 53, pinch the tear strip 41, and apply a pulling force to the top paper 2 through the tear strip 41. Since the separation groove 42 is inclined and forms a 45-degree angle with the top paper 2, the pulling force will be concentrated at the sharp corner of the separation groove 42, so that the initial force can be effectively poured into this sharp corner, easily opening the separation between the top paper 2 and the adhesive 1. As the pulling force continues to be applied, the top paper 2 is gradually torn along the separation groove 42. The inclined angle of the separation groove 42 makes the tearing process smoother. The gradually increasing tearing area allows the top paper 2 to be smoothly peeled off from the adhesive 1 in the form of a ring strip, avoiding excessive stretching and deformation of the adhesive 1, while ensuring the integrity of the peeling.

[0030] For peeling the bottom paper 3, the operator first squeezes the stop block 44. The stop block 44 generates radial force under the pressure, which pushes the bottom paper 3 towards the colloid 1. At this time, due to the 45-degree angle design of the separation groove 2 43, which is similar to the separation groove 1 42 of the top paper 2, the sharp corner of the bottom paper 3 can be smoothly separated from the separation groove 2 43 under the action of the stop block 44. Then, the bottom paper 3 is clamped by tweezers to increase the support force. In this process, the stop block 44 not only helps the bottom paper 3 to start separating, but also increases the resistance as an obstacle in the whole peeling process, making the process of the bottom paper 3 separating from the colloid 1 more stable and smooth.

[0031] During the conveying process, the protective components on the upper side of the upper bottom paper 2 come into play. The shield 51 is located above the separation groove 42 to prevent foreign objects from entering between the colloid 1 and the upper bottom paper 2 through the separation groove 42. The fixing block 53 is attached to the outside of the shield 51 to enhance the fixation of the shield 51, further ensuring the stability of the upper bottom paper 2 and preventing it from accidentally detaching from the colloid 1.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
