Description

Technical Field

[0001] This utility model belongs to the field of LED light strip processing technology, and specifically refers to a solder separator for LED lamp bead welding. Background Technology

[0002] The manufacturing process of LED decorative light strips involves a series of steps, including stripping parallel cables, applying flux, and soldering the LED panels. Existing LED light strip soldering equipment incorporates a solder bath, with the melting section at the top forming a large solder tank. Both solder addition and removal occur within this tank. To prevent short circuits during LED chip soldering, a solder separator is introduced, its structure tailored to the pad layout of the LED chips. This separator is fixed to the upper and lower drive structure of the soldering equipment, and its movement is coordinated with the LED chip soldering operation. Currently, existing solder separators are typically custom-made to fit the LED chip pads, primarily using wire cutting or laser cutting to divide the middle section into multiple areas. These areas isolate the solder feet on the LED chip pads, preventing cold solder joints or bridging that could cause open or short circuits, thus affecting the quality of the finished LED light strip. Summary of the Invention

[0003] The purpose of this invention is to provide a solder separator for LED chip soldering that is simple to manufacture and saves on manufacturing costs.

[0004] The purpose of this utility model is achieved as follows: A solder separator for LED lamp bead soldering, acting between the solder pot and the LED lamp bead, includes a mounting base and a solder separator part. One end of the mounting base extends upwards and is provided with a support rod. The solder separator part is located at the top of the support rod. The mounting base, support rod, and solder separator part form a "Z" shape, facilitating vertical movement in conjunction with the solder pot to evenly solder the LED lamp bead. The center of the solder separator part is hollowed out, and the size of the hollowed-out area is adapted to the corresponding LED lamp bead soldering surface. Two parallel or intersecting solder separator wires are provided on the hollowed-out surface of the solder separator part. The solder separator wires can divide the hollowed-out surface of the solder separator part into multiple areas, and the solder feet of the LED lamp bead can be divided into these areas.

[0005] Further optimization: Aligned grooves are provided on the two corresponding edges of the solder separator. The solder separator wire is fixed in the groove by welding. The groove can accurately determine the welding position of the solder separator wire, while enhancing the fixing strength and preventing the solder separator wire from falling off.

[0006] Further optimization: The mounting base is flat, and its flat surface is provided with strip holes for easy adjustment of the installation position. During the installation process, it can be moved left and right through the strip holes to finely adjust the precise position of the solder separator, the solder pot, and the LED beads.

[0007] Further optimization: one end of the mounting seat is provided with a crack connected with the strip-shaped hole, so that the strip-shaped hole has shrinkability.

[0008] Compared with the prior art, the utility model has the advantages of reducing the manufacturing difficulty of the tin isolation frame, cutting a notch matched with the LED lamp pearl only, then fixing the soldering tin wire on the tin isolation part according to the distribution of the soldering leg on the LED lamp pearl pad, realizing the separation of the LED welding in different areas, avoiding the problem of virtual welding or continuous welding between soldering legs when soldering tin, and the tin isolation frame made by the scheme has low cost and high production efficiency.

When the tin separation frame is moved up and attached to the LED lamp bead, the tin furnace with molten liquid tin is moved up and contacted with the LED lamp bead, and the soldering of the solder pins on the LED lamp bead is started. The tin separation wire can effectively prevent the adjacent solder pins from being connected, and avoid short circuit. In the actual production process, according to the distribution of the solder pins of the LED lamp bead, the number and shape of the tin separation wires can also be adjusted.
