Problems solved by technology

[0002] At present, people adopt manual production when making small ultra-thin chip inductors (as shown in Figure 1), and its production efficiency is low, and its technology is like this: a), stick the hollow iron core 100 on the copper On the band terminal 200; b), winding the coil 400 on the I-shaped iron core 300; c), flipping the I-shaped iron core 300 with the coil 400 in the hollow iron core 100; The two ends of the coil 400 are on the copper strip terminal 200 on both sides respectively; e), soldering tin—take the copper strip terminal 200 in the tin furnace for welding; f), print on the surface of the I-shaped iron core 300; g), test, Package

This method has the following disadvantages: ①. Since this production method requires tin furnace welding, it will cause certain damage to the copper wire coil of the product during tin furnace welding, so that some of the inductance products produced will have poor copper wire short circuits. situation, which will ultimately affect the reliability of the product

②. At the same time, as inductive products become smaller and thinner, the current manual production method is easy to cause damage to the product, and the manual production of products requires high man-hours, low efficiency and high scrap rate , resulting in high product cost

③. When winding the wire, one end of the I-shaped iron core must be clamped by the nozzle of the winding machine to drive the iron core to rotate to wind the wire. When the product is getting smaller and thinner, the nozzle is very It is easy to pinch or crack the end of the I-shaped iron core, resulting in low yield and affecting the reliability of the product

④. On the same product, either a small PAD copper strip terminal (as shown in Figure 2) or a large PAD copper strip terminal (as shown in Figure 3) is used, so the versatility of the product is not good

⑤. When producing products of different sizes, different winding nozzles and assembly fixtures need to be replaced, which will bring inconvenience to the current diverse and small-scale production methods of inductors
