Description

Technical Field

[0001] The invention is applied to the technical field of product bending, and particularly relates to a product bending method. Background Art

[0002] In the production process of various electronic products, each component will generate a certain temperature during the power-on process. Components with high requirements for ambient temperature need to be dissipated in time to prevent damage to the components caused by high temperature. At present, heat dissipation is mainly carried out through heat conduction methods such as thermal conductive silicone. In the use of thermal conductive silicone, in order to avoid poor contact and unsatisfactory heat transfer effect, the thermal conductive silicone needs to be pressed to ensure the flatness of the surface of the thermal conductive silicone so that it can be completely fitted with the contacted products. Since a layer of tear-proof copper foil is attached to the surface of the thermal conductive silicone to ensure its service life, the surface of the copper foil is prone to wrinkles or bulges during the bending and hemming process, which greatly reduces the thermal conductivity of the thermal conductive silicone. In addition, the thermal conductive silicone is prone to tearing or uneven temperature during use, resulting in a reduced service life. If a bending and pressing device with a simple structure, which can accurately control the pressing height, can bend the soft flow structure to the edge, and can prevent bending or bulging when bending and pressing the thermal conductive silicone with copper foil and keep the pressing surface flat, the above problems can be solved. Summary of the invention

[0006] Furthermore, the plurality of floating springs drive the pressing end of the floating pressure block to cooperate with the middle portion of the upper end of the heat-conducting product, and the cover plate drives the fixed pressure block to cooperate with the edge of the upper end of the heat-conducting product.

[0011] Furthermore, a stop surface is provided on one side of the heating carrier, and the stop surface cooperates with an overpressure prevention device on one side of the floating pressure block.

[0012] The beneficial effects of the present invention are as follows: the present invention solves the problem of wrinkles or bulging by means of floating pressing. When pressing the thermally conductive silicone, it will first pre-contact the middle of the thermally conductive silicone, and preferentially give a certain pressure to the surface of the thermally conductive silicone to ensure that the surface of the thermally conductive silicone is flat during the bending process, so that excess thermally conductive silicone is discharged outward to avoid bulging. For the bending wrinkles at the right angle at the lower left corner of the heat source, the problem of wrinkles can be solved by increasing the radius of the bend, increasing the space allowed for the overflow of the thermally conductive silicone, and reducing the extrusion of the right angle. The structure is simple, the pressing height can be precisely controlled, and the pressing effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] like Figures 1 to 5As shown, in this embodiment, the present invention includes a bending assembly 1 and a carrier assembly 2, wherein the bending assembly 1 includes a cover plate 3 and a pressing module 4, wherein the cover plate 3 is connected to the fixed end of the pressing module 4, wherein the cover plate 3 is in floating cooperation with the pre-pressing end of the pressing module 4, and wherein the cover plate 3 drives the fixed pressing end and the floating pressing end of the pressing module 4 to cooperate with the thermal conductive product 5 on the carrier assembly 2. It can be seen that the cover plate 3 drives the pressing module 4 to be pressed downward, and during the pressing process, the pre-pressing end of the pressing module 4 contacts the middle of the thermal conductive product 5, and is pressed downward for bonding, and after the bonding is completed, the entire product is pressed downward, which can effectively prevent wrinkles or bulging problems.

[0015] like Figures 1 to 3 As shown, in this embodiment, the pressing module 4 includes a floating pressing block 41 and a fixed pressing block 42, the cover plate 3 is connected to the upper end of the fixed pressing block 42, the upper end of the fixed pressing block 42 is provided with a floating groove 43, the floating pressing block 41 is slidably matched with the floating groove 43, the cover plate 3 is connected to the upper end of the floating pressing block 41, a plurality of floating springs 44 are provided between the cover plate 3 and the floating pressing block 41, and the cover plate 3 drives the pressing end of the floating pressing block 41 and the pressing end of the fixed pressing block 42 to cooperate with the thermal conductive product 5 on the carrier assembly 2. It can be seen that when the cover plate 3 is pressed down, the floating pressing block 41 first contacts the thermal conductive product 5, and then continues to press down the fixed pressing block 42 to fit the upper end of the thermal conductive product 5 as a whole and complete the pressing.

[0016] like Figure 2 and Figure 3 As shown, in this embodiment, the floating springs 44 drive the pressing end of the floating pressure block 41 to cooperate with the middle of the upper end of the thermally conductive product 5, and the cover plate 3 drives the fixed pressure block 42 to cooperate with the upper edge of the thermally conductive product 5. It can be seen that the floating springs 44 provide a downward pressure force to ensure that the surface of the thermally conductive silicone is flat during the bending process, so that the excess thermally conductive silicone is discharged outward to avoid bulging.

[0017] like Figure 1 As shown, in this embodiment, the carrier assembly 2 includes a heating base 21 and a heating platform 22, and the heat-conducting product 5 cooperates with the contour structure on the heating platform 22. It can be seen that the contour structure of the heating platform 22 is the same as the shape of the heat-conducting product 5, and the heat-conducting product 5 is relatively large in size. After the bending assembly 1 is pressed down, the heat-conducting product 5 can be bent.

[0018] like Figure 5As shown, in this embodiment, the heat-conducting product 5 includes a heat-conducting silicone rubber 51 and a copper foil 52, and the floating pressing block 41 and the fixed pressing block 42 cooperate to press the copper foil 52 and the heat-conducting silicone rubber 51. It can be seen that the copper foil 52 prevents the heat-conducting silicone rubber 51 from tearing under load, and the heat-conducting silicone rubber 51 can achieve efficient heat conduction and completely fit the heat source.

[0019] like Figures 1 to 3 As shown, in this embodiment, the bending assembly 1 further includes a pressing handle 6, which is connected to the upper end of the cover plate 3, and the pressing handle 6 drives the floating pressing block 41 and the fixed pressing block 42 to cooperate with the thermal conductive product 5. It can be seen that the pressing handle 6 can be used to achieve rapid lifting and lowering, and to achieve pressing and separation.

[0020] like Figure 1 As shown, in this embodiment, the lower pressing end of the fixed pressing block 42 is adapted to the contoured structure on the heating platform 22. It can be seen that the fixed pressing block 42 can drive the thermal conductive product 5 to be pressed into the contoured structure on the heating platform 22 to achieve simultaneous folding of multiple sides.

[0021] like Figure 1 As shown, in this embodiment, a stop surface is provided on one side of the heating platform 22, and the stop surface cooperates with the overpressure prevention fastener on one side of the floating pressure block 41. It can be seen that the stop surface can prevent the floating pressure block 41 from overpressing the thermal conductive product 5.

[0022] The working principle of the present invention is as follows: the heat-conducting product 5 to be bent is placed in the contoured structure on the heating platform 22 to complete preliminary positioning, the pressing handle 6 is driven to press down, the pressing end of the floating pressure block 41 contacts the middle of the thermally conductive silicone 51, and continues to press down, preferentially giving a certain pressure to the surface of the thermally conductive silicone to ensure that the surface of the thermally conductive silicone 51 is flat during the bending process, so that the excess thermally conductive silicone 51 is discharged outward to avoid bulging. After completing the preliminary pressing, the fixed pressure block 42 completes the bonding of the thermally conductive silicone 51 and the contoured structure on the heating platform 22 and continues to press, so as to achieve multilateral synchronous bending of the thermally conductive silicone 51.

[0023] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
