Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to an anti-warping heat-conducting double-sided adhesive tape. Background Art

[0002] Thermally conductive double-sided tape can provide good adhesion between two surfaces, allowing two objects to fit closely together, thereby achieving better heat transfer effects. It also usually has good insulation properties, which can prevent the conduction of current or signals and prevent short circuits between electronic devices. In addition, it can also be used to fill tiny gaps between objects to improve the efficiency of heat transfer. Gaps will increase the resistance to heat transfer, and filling with thermally conductive double-sided tape can reduce the gaps and improve the efficiency of heat transfer. Thermally conductive double-sided tape is generally composed of a substrate, a thermally conductive pressure-sensitive adhesive layer, and a release paper. The thickness of the thermally conductive pressure-sensitive adhesive layer is relatively thick, so its end is more likely to warp up when it touches other objects, and the warped part of the thermally conductive pressure-sensitive adhesive layer is easy to adhere to other objects and dust, thereby affecting the adhesion of this part of the tape and causing waste of thermally conductive double-sided tape. Utility Model Content

[0003] In view of the deficiencies of the prior art, the purpose of the present invention is to provide an anti-warping thermally conductive double-sided tape to solve the problem in the above background technology that the ends of some thicker thermally conductive double-sided tapes are prone to warping, affecting adhesion.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] To solve the problem that the ends of some existing thicker thermal conductive double-sided tapes are prone to warping, affecting adhesion, please refer to Figure 1-Figure 5 , an embodiment provided by the utility model:

[0023] An anti-warping thermally conductive double-sided tape comprises a tape main body component 1, and a reinforcement component 2 installed on the inner side wall of the tape main body component 1 for increasing the overall structural strength, and an anti-warping mechanism 3 rotatably installed inside the reinforcement component 2 is mainly used to suppress the head end of the thermally conductive double-sided tape at any time to prevent it from warping and affecting the subsequent gluing effect;

[0024] The reinforcement component 2 includes a sleeve structure 201 located at the center of the tape main body component 1, a screw rod 202 is threadedly connected to one side of the sleeve structure 201, and the anti-warping mechanism 3 includes a rubber ring 301 rotatably installed inside the sleeve structure 201, and both sides of the rubber ring 301 are fixedly connected with supporting blocks 302 with a width greater than the outer diameter of the sleeve structure 201, and an elastic structure 303 is fixedly installed on the front side of one of the supporting blocks 302, and a pressing component 304 is connected to the front end of the elastic structure 303, and the pressing component 304 is located on the outside of the tape main body component 1;

[0025] Specifically, by rotating the screw rod 202, the depth of one end thereof extending into the interior of the sleeve structure 201 is adjusted. When one end of the screw rod 202 does not extend into the inner circle of the sleeve structure 201, it indicates that the rubber ring 301 is not squeezed. At this time, the anti-warping mechanism 3 can rotate along the interior of the sleeve structure 201 under the action of external force, so that during the process of the thermal conductive double-sided adhesive tape, the thermal conductive tape portion in the tape main body component 1 is peeled off and rotates. In addition, due to the elasticity and reset function of the elastic structure 303 itself, the distance between the pressing component 304 and the supporting block 302 in the anti-warping mechanism 3 is correspondingly changed as the overall thickness of the thermal conductive double-sided adhesive tape gradually decreases. The rubber ring 301 is deformed so that the pressing component 304 is always attached to the outermost side of the tape main body component 1. When the tape is not in use, the pressing component 304 is adjusted to the head end of the tape by moving the anti-warping mechanism 3, and the screw rod 202 is rotated in the set direction to extend one end of the rubber ring 301 into the interior of the sleeve structure 201 to squeeze the rubber ring 301, thereby deforming the rubber ring 301 and suppressing the random movement of the entire anti-warping mechanism 3. In addition, the length of the rubber ring 301 is smaller than the length of the sleeve structure 201, so the opposite sides of the two supporting blocks 302 extend into the interior of the sleeve structure 201, thereby avoiding the deformation of the rubber ring 301, which causes the structure on both sides of the anti-warping mechanism 3 to tilt.

[0026] Reference Figure 1 , Figure 3 and Figure 4 As shown, the pressing component 304 includes a limiting cylinder 3041 fixedly connected to the front end of the elastic structure 303, a rotating column 3042 rotatably installed inside the limiting cylinder 3041 is arranged in a L-shaped manner, a pressing plate 3043 is fixedly installed at the front end of the rotating column 3042, and its length is greater than the width of the tape main body component 1, and the pressing component 304 also includes a shift bar 3044 fixedly installed on the back of the pressing plate 3043, and a through groove 3045 arranged in a T shape is provided between one side and the bottom of the front side of the pressing plate 3043, and a telescopic sleeve 305 is fixedly installed on the front side of the other supporting block 302, and a column structure 306 adapted to the bottom opening of the through groove 3045 is fixedly installed on the front end of the telescopic sleeve 305, and a card block structure 307 arranged in a T shape is fixedly installed on the front end of the column structure 306, and the length of the front side of the card block structure 307 is greater than the length of the through groove 3045, and the length of the back side of the card block structure 307 is adapted to the through groove 3045;

[0027] Specifically, when tearing off the tape, the block structure 307 can be pulled upward so that the column structure 306 is within the range of the through groove 3045, and then the pressing plate 3043 can be moved 180 degrees to one side, and the pressing plate 3043 can be adjusted to the side away from the tape main body component 1, so that the outer side of the tape main body component 1 is not blocked, and then it is more convenient to tear off a large amount of tape. As for tearing off a small amount of tape at a time, this operation is not necessary. After a large amount of tape is torn off, the pressing plate 3043 can be adjusted to the head end of the tape for pressing, and the shift strip 3044 is used to fit the cut surface of the tape, which can further improve the anti-warping effect of the tape. At this time, the block structure 307 is used to engage in the T-shaped through groove 3045 to prevent the pressing plate 3043 from rotating without reason.

[0028] Reference Figure 2 As shown, the tape main body component 1 includes a base structure 101 arranged in a ring shape. The base structure 101 is preferably made of plastic material or rigid material according to actual conditions. The outer surface of the base structure 101 is wound with a thermally conductive pressure-sensitive colloid 102 and a release paper 103. The thermally conductive pressure-sensitive colloid 102 has a high thermal conductivity and can effectively conduct heat, so that heat energy can be quickly transferred between contacting objects, thereby improving the heat conduction efficiency. The reinforcement component 2 also includes a support rod 203 fixedly installed on the outer surface of the sleeve structure 201, and one end of the support rod 203 is fixedly connected to the inner wall of the base structure 101.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
