Detailed Embodiments
[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the following will further describe the present application in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0027] Please refer to Figures 1 to 3 Figures 1 to 3 , a stable LED bracket, including a bracket cup bottom 1, a coating 2 provided on the bracket cup bottom 1, an insulating rubber strip 4 provided on the bracket cup bottom 1 and dividing the coating 2 into a plurality of blocks 3, and a first insulating pressing strip 5 and a second insulating pressing strip 6 for connecting adjacent blocks 3 and the coating 2 between adjacent blocks 3.
[0028] For a stable LED bracket of the present application, the first insulating pressing strip and the second insulating pressing strip can effectively press the gap between the insulating rubber strip and the bottom coating, reduce the shaking of the cup bottom, thereby improving the stability of the wire bonding operation, and effectively avoiding the problem of frequent wire breakage anomalies in the wire bonding operation.
[0029] Further, as a preferred implementation manner of this solution rather than a limitation, the block 3 includes a first block 31, a second block 32, a third block 33, a fourth block 34, a fifth block 35, and a sixth block 36 arranged in an S shape in sequence.
[0030] In this embodiment, by arranging the blocks in an S shape, not only the structural stability of the bracket is improved, but also the layout of the wire bonding operation is optimized. This S-shaped arrangement makes the connection between each block more compact, reduces space waste, and at the same time provides a more reasonable path for wire bonding, reducing the operation difficulty caused by space limitations. In addition, the S-shaped layout helps to evenly distribute the stress during the wire bonding process and reduce the risk of wire breakage caused by local stress concentration.
[0031] Further, as a preferred implementation manner of this solution rather than a limitation, the areas of the first block 31, the third block 33, and the fifth block 35 are respectively smaller than the areas of the second block 32, the fourth block 34, and the sixth block 36.
[0032] In this embodiment, this area distribution can optimize the layout of the solder joints, so that the smaller blocks can adapt to the size differences of the chips, thereby ensuring that each solder joint can obtain an appropriate wire bonding space and avoiding problems such as insecure soldering or wire breakage caused by insufficient space.
[0033] Further, as a preferred implementation manner of this solution rather than a limitation, the first block 31 and the second block 32 are on the same straight line, the third block 33 and the fourth block 34 are on the same straight line, and the fifth block 35 and the sixth block 36 are on the same straight line.
[0034] In this embodiment, the block layout on the bottom of the bracket cup can be made more regular and orderly, thereby improving the symmetry and stability of the structure. This design can reduce the stress concentration between blocks, lower the risk of structural deformation, and thus improve the reliability of wire bonding operations and the service life of LED products.
[0035] Further, as a preferred implementation manner of this solution rather than a limitation, the first insulating strip 5 is respectively connected to the first block 31, the second block 32, the third block 33, the fourth block 34, and the plating layer 2 therebetween.
[0036] In this embodiment, through the connection function of the first insulating strip 5, the positional relationship between adjacent blocks can be effectively fixed, the relative movement between blocks can be reduced, and thus the stability of the structure can be improved. At the same time, the first insulating strip 5 can also fill the gaps between blocks and between the blocks and the plating layer, reduce stress concentration, lower the risk of structural deformation, and further improve the reliability of wire bonding operations and the service life of LED products.
[0037] Further, as a preferred implementation manner of this solution rather than a limitation, the second insulating strip 6 is respectively connected to the third block 33, the fourth block 34, the fifth block 35, the sixth block 36, and the plating layer 2 therebetween.
[0038] In this embodiment, through the connection function of the second insulating strip 6, the positional relationship between adjacent blocks can be effectively fixed, the relative movement between blocks can be reduced, and thus the stability of the structure can be improved. At the same time, the second insulating strip 6 can also fill the gaps between blocks and between the blocks and the plating layer, reduce stress concentration, lower the risk of structural deformation, and further improve the reliability of wire bonding operations and the service life of LED products.
[0039] Further, as a preferred implementation manner of this solution rather than a limitation, the width of the first insulating strip 5 is L, and the spacing distance between the first block 31, the second block 32 and the third block 33, the fourth block 34 is S, where L > S.
[0040] In this embodiment, by ensuring that the width L of the first insulating strip 5 is greater than the spacing distance S between adjacent blocks, the first insulating strip 5 can completely cover and connect the gaps between adjacent blocks and connect the first block 31, the second block 32, the third block 33, and the fourth block 34, thereby improving the stability and connection reliability of the structure. This design can effectively reduce the relative movement and stress concentration between blocks, lower the risks of structural deformation and wire bonding breakage, and further improve the service life and reliability of LED products.
[0041] Further, as a preferred embodiment of this solution rather than a limitation, the width of the second insulating pressing strip 6 is D, and the spacing distance between the third block 33, the fourth block 34 and the fifth block 35, the sixth block 36 is B, where D > B.
[0042] In this embodiment, by ensuring that the width D of the second insulating pressing strip 6 is greater than the spacing distance B between adjacent blocks, the second insulating pressing strip 6 can completely cover and connect the gaps between adjacent blocks and connect the third block 33, the fourth block 34, the fifth block 35, and the sixth block 36, thereby improving the structural stability and connection reliability. This design can effectively reduce the relative movement and stress concentration between blocks, reduce the risk of structural deformation and wire bonding breakage, and further improve the service life and reliability of LED products.
[0043] Further, as a preferred embodiment of this solution rather than a limitation, the lengths of the first insulating pressing strip 5 and the second insulating pressing strip 6 are H, and the length of the bracket cup bottom 1 is h, where H < h.
[0044] In this embodiment, by setting the lengths H of the first insulating pressing strip 5 and the second insulating pressing strip 6 to be less than the length h of the bracket cup bottom 1, it can be ensured that the sub-potting glue does not exceed the range of the bracket cup bottom, thereby avoiding interference of the sub-potting glue with other components or process steps. This design can improve the assembly efficiency and reliability of the LED bracket, and reduce errors and rework in the production process.
[0045] Further, as a preferred embodiment of this solution rather than a limitation, both ends of the first insulating pressing strip 5 and the second insulating pressing strip 6 are spaced from both ends of the bracket cup bottom 1.
[0046] In this embodiment, by keeping a certain spacing between both ends of the first insulating pressing strip 5 and the second insulating pressing strip 6 and both ends of the bracket cup bottom 1, it can be avoided that the sub-potting glue directly contacts the edge of the bracket cup bottom, thereby reducing the risk of stress concentration and structural deformation. This design can improve the structural stability and reliability and extend the service life of LED products.
[0047] The working principle of this embodiment is as follows:
[0048] A stable LED bracket of the present application can effectively press the gap between the insulating rubber strip and the bottom plating layer through the first insulating pressing strip and the second insulating pressing strip, reduce the shaking of the cup bottom, thereby improving the stability of the wire bonding operation and effectively avoiding the problem of frequent wire breakage abnormalities in the wire bonding operation.
[0049] The above are the implementation manners provided in combination with specific contents, and it is not determined that the specific implementation of this application is only limited to these descriptions. Any method structure similar to that of this application, or several technical deductions or replacements made on the premise of the concept of this application, shall be regarded as the protection scope of this application.
