Description

Technical Field

[0001] This utility model belongs to the technical field of electronic components, specifically relating to a welding guide fixture. Background Technology

[0002] Currently, electronic components are becoming increasingly smaller, leading to a greater need to ensure the quality of soldering between small parts, especially for miniaturized internal conductors. Ensuring coaxiality and weld dimensions after soldering often presents significant technical challenges. Common soldering methods are characterized as follows: First, manual control of positioning and hand-soldering. However, this method cannot guarantee soldering quality, resulting in poor consistency, high defect rates, low efficiency, and is unsuitable for mass production. Second, automated equipment is used, but this equipment is expensive, complex to debug, and often cannot be used independently, requiring specialized tooling. When frequent product model changes or small-batch production are needed, production costs increase significantly, resulting in low cost-effectiveness. Furthermore, this equipment has limitations; it is suitable for soldering cup-shaped internal conductors but not for soldering straight-hole internal conductors. All of these soldering methods have significant limitations, affecting the soldering quality and efficiency of small components in terms of production quality, efficiency, processing costs, and flexibility.

The other side of the support frame has a first through hole, which connects to the flat-bottomed U-shaped through groove. There are multiple through holes, and the number of support rods and positioning cores is the same as the number of first through holes. Each first through hole is equipped with a positioning core located on one side of the flat-bottomed U-shaped through groove. One end of each support rod is inserted into and connected to one end of a product to be welded. The other end of the product to be welded extends into one end of a first through hole, passes through the flat-bottomed U-shaped through groove, and then inserts into the positioning core at the other end of the first through hole, thereby positioning the product to be welded.

[0004] Preferably, the flat-bottomed U-shaped channels are arranged along the length of the support frame, and the two ends and the top of the flat-bottomed U-shaped channels are open structures.

[0005] Preferably, each of the first through holes and the flat-bottomed U-shaped through grooves are arranged perpendicularly and intersectingly to each other.

[0006] Preferably, the plurality of first through holes are arranged at equal intervals in a straight line, and the diameter of each first through hole is the same.

[0007] Preferably, each of the support rods has a circular hole at one end; the circular hole of each support rod is inserted into and connected to one end of a product to be welded.

[0008] Preferably, each of the positioning cores is cylindrical and has a through hole extending through it axially.

[0009] Preferably, each of the support rods is cylindrical.

[0010] The beneficial effects of this utility model are:

[0011] The components used in this invention have a simple design structure, are easy to process, and have a short processing cycle, greatly reducing the production cost. All components are detachable and can be adapted to different sizes of positioning cores and support rods depending on the product. This makes it suitable not only for small-batch production but also for large-batch production, and for production situations involving frequent product type changes, thus offering high flexibility. This invention provides accurate positioning, minimal error, and reliable welding quality. It not only solves the problems of poor consistency, low efficiency, and high defect rate associated with manual flux welding but also addresses the issues of high cost, complex debugging, and limited applicability of automated welding equipment.

There are multiple through holes 102, and the number of support rods 3 and positioning cores 2 is the same as the number of through holes 102. Each through hole 102 is located on one side of the flat-bottomed U-shaped through groove 101, and a positioning core 2 is installed thereon. One end of each support rod 3 is inserted into one end of a product 4 to be welded. The other end of the product 4 extends into one end of a through hole 102, passes through the flat-bottomed U-shaped through groove 101, and is then inserted into the positioning core 2 at the other end of the through hole 102 to position the product 4 to be welded.

[0023] As mentioned above, the number of through holes 102 is the same as the number of products 4 to be soldered. Therefore, multiple products 4 to be soldered can be soldered at once using the tooling of this utility model. After positioning, the multiple products 4 to be soldered in each batch are in the same position. After the products 4 to be soldered are positioned, mechanical welding or soldering can be used, and the welding method is relatively simple.

[0027] Furthermore, the plurality of through holes 102 are arranged at equal intervals in a straight line, and each through hole 102 has the same diameter.

[0028] As mentioned above, the multiple through holes 102 are arranged at equal intervals in a straight line, so that the relative positions of the multiple products 4 to be welded installed in the support frame 1 are uniform.

[0029] Furthermore, each of the support rods 3 has a circular hole 301 at one end; the circular hole 301 of each support rod 3 is inserted into and connected to one end of a product 4 to be welded.

[0030] The circular hole 301 mentioned above is a blind hole.

[0031] Furthermore, each of the positioning cores 2 is cylindrical and has a through hole 201 extending through it axially.

[0032] The aforementioned through hole 201 is used for plugging and connecting with the other end of the product 4 to be welded.

[0033] Furthermore, each of the support rods 3 is cylindrical in shape.

[0034] As mentioned above, the diameter of the support rod 3 is the same as the diameter of the through hole 102, and they are fitted with a clearance.
