[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides Figure 1-Figure 5 A conductive adhesive with good heat resistance shown in the figure includes a skeleton 6 and a conductive adhesive roll 5 wound around the outer ring of the skeleton 6. After the conductive adhesive roll 5 is pulled out and used, there is usually excess conductive adhesive. During actual use, the pulled conductive adhesive is difficult to rewind back along the original path, and it is difficult to align after rewinding, which will cause waste of the conductive adhesive.

[0026] Therefore, the present invention also includes a first limiting plate 1 and a second limiting plate 2, which are fixedly connected by a connecting assembly. The middle parts of the first limiting plate 1 and the second limiting plate 2 are fixedly provided with limiting holes, and a rotating drum 7 is movably fitted between the two limiting holes. A chassis 8 is fixedly provided at the outer ring of the bottom of the rotating drum 7, and the chassis 8 and the first limiting plate 1 are movably fitted. A push rod 9 is fixedly provided at one end of the rotating drum 7 extending out of the top of the second limiting plate 2. The skeleton 6 is movably sleeved on the outer ring of the rotating drum 7, and is respectively connected with the first limiting plate 1 and the second limiting plate 2. The second limit plate 2 is movably fitted together. When it is necessary to pull back the excess conductive glue, one hand holds the first limit plate 1 and the second limit plate 2, and the other hand rotates the push rod 9 to drive the rotating drum 7 and the chassis 8 to rotate, thereby driving the skeleton 6 to rotate, so that the pulled-out conductive glue can be better reeled back under the limiting guidance of the first limit plate 1 and the second limit plate 2, and no reeling deviation will occur during the reeling process, thereby solving the problem that the existing conductive glue is difficult to reel back again after being pulled out as a whole, and it is difficult to align after reeling, which will cause waste of use.

[0027] Furthermore, the diameter of the conductive adhesive roll 5 is smaller than the diameter of the first limiting plate 1 . This configuration prevents the pulled-out conductive adhesive from sliding sideways from the edge of the first limiting plate 1 or the second limiting plate 2 .

[0028] Furthermore, the connecting assembly includes a connecting rod 3, which is fixed on the top near the edge of the first limit plate 1. There are six connecting rods 3, and the six connecting rods 3 are evenly distributed in a ring with the center of the first limit plate 1 as the center point. Six slots corresponding to the positions of the connecting rods 3 are fixed on the second limit plate 2. A limiting plate is fixed on the top of the connecting rod 3, and a threaded rod is provided on the top of the limiting plate. One end of the threaded rod extending out of the upper surface of the second limit plate 2 is threadedly connected with a nut 4. The limiting plate and the lower surface of the second limit plate 2 fit each other. After the skeleton 6 is put into the rotating drum 7, the conductive film 5 is placed in place, and then the threaded rod is passed through the slot and tightened with the nut 4. The second limit plate 2 is fixed by the cooperation of the limiting plate. This arrangement facilitates the installation, fixation and disassembly of the second limit plate 2, thereby facilitating the replacement of the conductive film 5.

[0029] In addition, by installing the six connecting rods 3 , the outer circle of the conductive film 5 is restricted, so as to prevent the conductive glue on the conductive film 5 from loosening and expanding, thereby improving the placement stability of the conductive film 5 .

[0030] By installing the six connecting rods 3, when the push rod 9 is rotated to rewind, the connecting rods 3 can press down the excess conductive adhesive that is pulled out, so that it can be rewound better without manual pressing.

[0031] In order to allow the rotating drum 7 and the chassis 8 to drive the skeleton 6 to rotate when they rotate, an auxiliary component is provided on the rotating drum 7, and the auxiliary component includes a connecting plate 10. There are four connecting plates 10, and the four connecting plates 10 are evenly distributed in a ring and fixed at the inner circle of the rotating drum 7. The rotating drum 7 is provided with a long hole 14 corresponding to the position of the connecting plate 10, and a movable plate 15 is slidably provided on the inner wall of the long hole 14. Two movable grooves symmetrically distributed about the center line of the connecting plate 10 are fixedly provided in the internal structural layer of the connecting plate 10. The movable groove runs through the side of the connecting plate 10, and a sleeve rod 11 is fixedly provided at the end of the movable groove. A telescopic rod 12 is slidably provided inside the sleeve rod 11. One end of the telescopic rod 12 movably extends out of the sleeve rod 11 and is fixedly connected to the movable plate 15. A spring 13 movably sleeved at the outer circle of the sleeve rod 11 and the telescopic rod 12 is fixedly connected between the movable plate 15 and the end of the movable groove.

[0032] Specifically, when the skeleton 6 is sleeved on the outer circle of the rotating drum 7, the movable plate 15 is retracted into the inner long hole 14, so that the telescopic rod 12 extends into the sleeve rod 11, and the spring 13 is compressed, thereby acting in the opposite direction on the movable plate 15, applying a certain thrust to the movable plate 15, so that the four movable plates 15 evenly apply thrust to the skeleton 6, supporting the skeleton 6, so that when the rotating drum 7 and the chassis 8 are rotating, the skeleton 6 can be driven to rotate.

[0033] Furthermore, the side of the movable plate 15 away from the connecting plate 10 is in an arc-shaped structure. This arrangement avoids the problem that the movable plate 15 blocks the frame 6 from moving downward and enveloping the rotating drum 7.

[0034] Furthermore, a plurality of anti-slip strips evenly distributed in a ring shape are fixedly provided on the outer ring of the nut 4. The provision of the anti-slip strips facilitates the rotation of the nut 4.

[0035] Furthermore, the conductive adhesive on the conductive film roll 5 includes a conductive copper surface 501, a conductive adhesive surface 502 and a separation paper 503 from the outside to the inside. When using the conductive adhesive, pull the conductive adhesive out of the conductive film roll 5, peel off the separation paper 503, and then stick it where needed.
