[0028] Example 1
[0029] Combination Figures 1 to 3 As shown, the patch fixture of the present invention is schematically shown, including a base 10 and a plurality of connecting components 20.
[0030] like Figure 1 and Figure 3 , the base 10 is provided with an adsorption area 111, which is magnetically conductive and can be adsorbed with magnetic parts. The connecting component 20 is provided with a magnetic part 30, which is preferably a high temperature resistant magnet, such as a samarium cobalt magnet or an aluminum nickel cobalt magnet, which can work in an environment above 300°C. The magnetic part 30 is connected to the adsorption area 111 by magnetic adsorption, so the position of the connecting component 20 on the adsorption area 111 can be flexibly adjusted by the production personnel. In the actual production process, the setting position of the connecting component 20 in the adsorption area 111 can be changed according to the actual design position of the connecting structure 51 of the lamp board 50 to adapt to lamp boards 50 of various sizes. The connecting component 20 is used to connect with the connecting structure 51 on the lamp board 50, and the magnetic part 30 is used to magnetically adsorb the connecting structure 51. The magnetic adsorption connection method between the connecting component 20 and the base 10 can not only flexibly adapt to lamp boards 50 of various sizes, but also facilitate the disassembly and assembly of the lamp board 50 and the connecting component 20, greatly improving the production efficiency and reducing the labor cost.
[0031] Combination Figure 2 and Figure 3 , the base 10 is provided with a plurality of magnetically conductive connecting plates 11, the connecting plates 11 have an adsorption area 111, and the connecting plates 11 are preferably iron plates, which have the advantage of low material cost under the premise of realizing the function of magnetic adsorption with the magnetic member 30. Among them, the base 10 is provided with a plurality of mounting through holes 12, the number of the mounting through holes 12 is consistent with the number of the connecting plates 11, and each connecting plate 11 corresponds to a mounting through hole 12, the area of the connecting plate 11 is larger than the opening area of the mounting through hole 12, the connecting plate 11 is covered on the mounting through hole 12, and the surroundings of the connecting plate 11 are fixed to the surroundings of the mounting through hole 12 by existing fasteners 40 such as screws or bolts, so as to realize the detachable connection between the connecting plate 11 and the base 10, so as to facilitate the maintenance and replacement of the connecting plate 11.
[0032] In order to limit the degree of freedom of the light board 50 after being connected with the light board 50, the connecting component 20 is provided with a connecting groove 21, such as Figure 3 The magnetic member 30 is arranged opposite to the connecting groove 21, and the connecting structure 51 is detachably embedded in the connecting groove 21. The connecting groove 21 has a plurality of inner side walls, and the connecting structure 51 has a plurality of outer side walls. When the connecting structure 51 is embedded in the connecting groove 21, the outer side wall of the connecting structure 51 fits against the inner side wall of the connecting groove 21. Therefore, the connecting groove 21 of the connecting component 20 can limit the freedom of the lamp board 50 on its plane, and the magnetic member 30 and the connecting structure 51 are magnetically adsorbed to limit the freedom of the lamp board 50 in its normal direction, thereby stably connecting the lamp board 50 to the base 10 so as to perform patch processing on the lamp board 50.
[0033] Further, the connecting component 20 is provided with a housing chamber 22, and the magnetic component 30 is located in the housing chamber 22. The housing chamber 22 is used to accommodate and install the magnetic component 30 and provide protection for the magnetic component 30. The housing chamber 22 is adjacent to the connecting groove 21, and the bottom surface of the connecting groove 21 is provided with a process hole 211 connected to the housing chamber 22, so that the bottom surface of the connecting groove 21 is annular. The end surface of the connecting structure 51 is provided with a screw hole 511 (blind hole), and the orifice of the screw hole 511 is likely to have burrs during the production process. Therefore, the setting of the process hole 211 can accommodate the burrs of the orifice of the screw hole 511, so that the connecting structure 51 can be completely embedded in the connecting groove 21, avoiding the burrs from interfering with the bottom surface of the connecting groove 21. Preferably, the bottom surface of the connecting groove 21 is made of a magnetic conductive material, so that the connection between the magnetic component 30 and the connecting structure 51 is more stable. In this embodiment, the inner wall of the connecting component 20, the connecting groove 21, and the housing chamber 22 is an integrally formed structure and is made of a magnetic conductive material.
[0034] In this embodiment, there is only one connecting plate 11, which is annular, that is, the adsorption area 111 is arranged in a ring shape on the base 10. This arrangement is suitable for multiple connecting structures 51 arranged around the lamp board 50, and each connecting structure 51 corresponds to a connecting component 20, so that the lamp board 50 is stably connected to the base 10 on all sides to avoid the edge warping of the lamp board 50.
[0035] In order to support the lamp board 50, so as to prevent the lamp board 50 from being accidentally bent and deformed during the patch processing, such as Figure 2 and Figure 3 The base 10 is provided with a first connection cavity 13, the bottom surface of the first connection cavity 13 is provided with a second connection cavity 14, the bottom surface of the second connection cavity 14 is provided with an adsorption area 111, the connection component 20 is located in the second connection cavity 14, the first connection cavity 13 is used to store the light board 50, and the light board 50 is attached to the bottom surface of the first connection cavity 13, that is, the bottom surface of the first connection cavity 13 can support the light board 50 to prevent the light board 50 from deforming during the patch processing. The second connection cavity 14 is not only used to store and install the connection component 20, but also to accommodate the connection structure 51 of the light board 50, so that the light board 50 can be laid flat on the bottom surface of the first connection cavity 13.
[0036] Example 2
[0037] The difference between this embodiment and Embodiment 1 is that there are multiple connecting plates 11, that is, there are multiple adsorption areas 111, and the multiple connecting plates 11 are arranged along a circular trajectory on the base 10, so that the multiple adsorption areas 111 together form a circular trajectory. This structure can also be suitable for multiple connecting structures 51 arranged around the lamp board 50, so that the lamp board 50 is stably connected to the base 10 on all sides to avoid the edge warping of the lamp board 50.
