DETAILED DESCRIPTION

[0035] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] See also Figure 1-Figure 13 The present invention provides a lamp bead for a leather wire lamp, comprising a substrate 1, a material placement groove 18 is provided on the substrate 1, a bracket 2 is embedded in the material placement groove 18, a chip 3 is adhered to the middle of the bracket 2 through silicone, and a lens for blocking the chip 3 is provided above the bracket 2 (not shown in the figure, it is an existing conventional structure); it also includes: a support plate 4 that is pressed and matched with the chip 3, a plurality of through grooves 5 are provided on the support plate 4, a movable groove 6 is provided in the middle of the bracket 2, a plurality of hinges are rotatably connected between the bottom surface of the movable groove 6 and the support plate 4, a rotating groove 7 is provided on the side of the movable groove 6, a rotating member is rotatably connected in the rotating groove 7, and the end of the rotating member is pressed and matched with the end of the through groove 5;

[0038] In the present application, the flowing silica gel is placed into the movable groove 6, and then the middle of the top surface of the chip 3 is adsorbed by a manipulator or other equipment, so that the chip 3 contacts the support plate 4 and drives the support plate 4 to move downward, so that the hinge moves, and multiple hinges make the support plate 4 move smoothly without tilting, and the hinge of the hinge goes deep into the rotating groove 7 to fix the hinge, thereby ensuring the position of the support plate 4, and the moving silica gel enters the through groove 5 and submerges the top surface of the support plate 4;

[0039] When the hinge rotates, the rotating member is driven to rotate. On the one hand, the bottom of the rotating member presses against the silicone in the rotating groove 7, and on the other hand, the top of the rotating member rotates to press against the through groove 5, press against the fixed support plate 4, and act on the silicone, so that the silicone fills the space between the chip 3 and the support plate 4 to ensure the adhesion effect;

[0040] Finally, wait for the silicone to solidify, and the installation of chip 3 is completed;

[0041] Among them, a gold wire is arranged between the existing chip 3 and the bracket 2, which is fixed by a lens and the distribution of sweaty feet, etc., which will not be elaborated in this application.

[0042] The hinged member comprises a first hinged plate 8 hinged to the bottom edge of the support plate 4, and a second hinged plate 9 is hinged between the bottom end of the first hinged plate 8 and the bottom surface of the movable groove 6;

[0043] When the support plate 4 moves downward, the first hinge plate 8 and the second hinge plate 9 rotate, so that the support plate 4 moves vertically and smoothly, and the hinge of the first hinge plate 8 and the second hinge plate 9 enters the rotation groove 7 and acts on the rotating member.

[0044] The rotating member includes a rotating shaft 10 rotatably connected to the bracket 2, and a first rotating plate 11 and a second rotating plate 12 are rotatably connected at the edge of the rotating shaft 10. The top end of the second hinged plate 9 penetrates into the rotating groove 7 and is pressed and matched with the second rotating plate 12.

[0045] The hinge of the first hinge plate 8 and the second hinge plate 9 presses against the second rotating plate 12, so that the second rotating plate 12 and the first rotating plate 11 rotate. The second rotating plate 12 rotates to press the silicone in the rotating groove 7 for easy fixation. The first rotating plate 11 rotates to press the through groove 5, which on the one hand fixes the position of the support plate 4, and on the other hand makes the silicone active to ensure the adhesion area and fixing effect between the chip 3 and the support plate 4.

[0046] The through groove 5 is in a "+" shape, and a pressing groove 13 connected to the through groove 5 is opened at the edge of the support plate 4. The pressing groove 13 is in a trumpet shape and is pressed and matched with the first rotating plate 11. When the chip 3 presses against the support plate 4, the first rotating plate 11 rotates and presses into the pressing groove 13, and is pressed and fixed with the end of the through groove 5. This method helps the pressing silicone to move, so that the silicone is fully filled between the chip 3 and the support plate 4, thereby increasing the connection effect.

[0047] A plurality of through holes 14 are provided in the middle of the support plate 4, and the middle of the support plate 4 is in the shape of a groove, so that the silica gel can enter between the support plate 4 and the chip 3 and ensure the adhesion area of ​​the silica gel.

[0048] The rotation groove 7 is in a shape that is larger on the inside and smaller on the outside, and the hinged portion between the second hinge plate 9 and the first hinge plate 8 is plugged and fixed to the rotation groove 7 .

[0049] The bottom surface of the support plate 4 is fixedly connected with an insertion rod 15, and the bracket 2 is provided with a socket 16 which is plugged into and cooperates with the insertion rod 15. When the support plate 4 moves downward, the insertion rod 15 is driven to be inserted into the socket 16, which ensures the stability of the support plate 4 on the one hand, and stabilizes the position of the support plate 4 on the other hand, while also stabilizing the position of the hinge in the rotating groove 7.

[0050] An elastic cone block 17 that cooperates with the insertion hole 16 is fixedly connected to the top of the insertion rod 15. The top surface size of the elastic cone block 17 is larger than the bottom surface size of the insertion rod 15. The elastic cone block 17 squeezes into the insertion hole 16 to prevent the insertion rod 15 from escaping from the insertion hole 16.

[0051] Embodiment 2

[0052] See also Figure 1-Figure 2 and 14- Fig.17 A lamp bead plate 19 is provided on the substrate 1, and a positive electrode pad 201, a negative electrode pad 202 and an isolation belt 203 are provided on the bracket 2. The isolation belt 203 is used to isolate the positive electrode pad 201 from the negative electrode pad 202. The isolation belt 203 separates the positive electrode pad 201 from the negative electrode pad 202 so that when the lamp bead is welded on the leather wire lamp line by a soldering iron or laser, a short circuit caused by tinning or tinning of the lamp bead can be prevented;

[0053] The isolation belt 203 separates the negative electrode pad 202 of the lamp bead, so that the solder paste or solder cannot cross the isolation belt 203 during the welding process, which ensures the physical isolation of the lamp bead welding and avoids the problems of soldering and bridging. During the welding process, the transfer and distribution of heat is crucial;

[0054] The isolation zone 203 helps to distribute heat evenly and prevent excessive heat accumulation from causing solder paste or solder to flow, thereby reducing the risk of soldering and tinning. The isolation zone 203 separates the positive electrode pad 201 and the negative electrode pad 202, further reducing the possibility of short circuit. By effectively preventing soldering and tinning, the production process of the special lamp beads for leather-line lamps becomes more stable and reliable, thereby improving the overall performance and stability of leather-line lamps.

[0055] It is worth noting that the isolation belt 203 is a convex block protruding from the bottom surface of the bracket 2 toward the bottom of the bracket 2, and the convex block is an intermediate plastic part provided at the bottom of the bracket 2 and located on the gap separating the positive electrode pad 201 and the negative electrode pad 202;

[0056] The bump, i.e. the middle plastic part, can accurately separate the positive electrode pad 201 and the negative electrode pad 202, so that the welding parts can more accurately position and weld the lamp beads. This helps to improve the accuracy and stability of welding. The isolation belt 203 can effectively prevent the lamp beads from being tinned or connected during the welding process, thereby avoiding the occurrence of short circuits.

[0057] This can improve the quality and reliability of the lamp bead plate 19. Lamp beads without tinning or connecting can work more stably, extending the service life of the lamp beads. The design of the isolation belt 203 makes the production process smoother, reduces problems and troubles in the production process, and improves production efficiency and management level.

[0058] It is worth noting that: the material placement groove 18 on the bracket 2 is in a bowl shape and is used to accommodate the chip 3 (LED chip); the positive electrode pad 201 and the negative electrode pad 202 are both plated at the bottom of the material placement groove 18, the positive electrode pad 201 is electrically connected to the positive electrode of the chip 3, and the negative electrode pad 202 is electrically connected to the negative electrode of the chip 3;

[0059] The material placement groove 18 further improves the fixation and stability of the chip 3, ensures its accurate position on the bracket 2, and is beneficial to improving the welding accuracy and the quality of the lamp beads. By electrically connecting the chip 3 with the positive electrode pad 201 and the negative electrode pad 202, it can ensure that the current flow of the chip 3 is correct, which is beneficial to improving the working efficiency and stability of the chip 3.

[0060] It is worth noting that a fluorescent glue layer 204 for packaging the chip 3 is disposed in the material placement groove 18 , and a light guide plate 205 is covered on the fluorescent glue layer 204 .

[0061] The presence of the fluorescent glue layer 204 can protect the chip 3 from the influence of the external environment and increase its service life. The light guide plate 205 can evenly guide the light emitted by the fluorescent glue layer 204 to all directions to improve the lighting effect of the light strip. The light guide plate 205 can also improve the overall aesthetics of the light strip.

[0062] It is worth noting that: the lamp beads for the leather wire lamp, the lamp beads of the lamp bead plate 19 and the lamp bead bracket 2 are separated by a reserved gap using an intermediate plastic part protruding, and the lamp beads are welded by a soldering iron or laser. The intermediate plastic part is used as an isolation belt 203 to prevent the lamp beads from being tinned or connected during the production process, causing a short circuit. The lamp beads are mostly used in leather wire lamps or directly welded on the wires.

[0063] The advantage of the middle plastic part is that it not only serves as the isolation belt 203, but also can serve as a part of the leather wire lamp line after the lamp bead board 19 is assembled, thereby enhancing the durability and aesthetics of the leather wire lamp. At the same time, the design of the middle plastic part can also protect the lamp beads from external damage to a certain extent, thereby improving the safety of the lamp bead board 19.

[0064] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
