Description

Technical Field

[0001] The utility model relates to the technical field of circuit board welding technology, in particular to a circuit board welding auxiliary tooling. Background Art

[0002] Circuit board welding is an important technology in electronic manufacturing, which is mainly used to connect electronic components to circuit boards to realize circuit functions.

[0003] Among them, manual soldering is one of the most basic circuit board soldering methods, which uses a manual soldering iron to heat the solder wire to a molten state; then, it is applied to the components and circuit boards that need to be soldered. However, this method is prone to problems such as poor soldering and uneven soldering temperature, so the soldering temperature and time need to be strictly controlled.

[0004] In addition, hot air soldering iron welding is also a handheld circuit board welding method, which is suitable for small batch production and DIY production. The hot air soldering iron welding mainly uses a hot air soldering iron to heat the solder wire to a molten state; then, it is applied to the components and circuit boards that need to be soldered.

[0005] Furthermore, in the soldering process of the circuit board, in addition to manual soldering, there are also automatic soldering methods such as wave soldering or reflow soldering. However, whether it is manual soldering or automatic soldering; during the soldering process, the circuit board needs to be securely clamped to avoid the defect of accidental sliding displacement of the circuit board during soldering, which may cause the solder joint to shift.

[0006] Based on this, Chinese patent CN208977026U discloses a welding tool for circuit boards, which includes a bottom plate, a vertical plate and a clamping head. There are two vertical plates, both of which are vertically mounted on the bottom plate. A rotating shaft is arranged on the inner side of the two vertical plates, and the two rotating shafts are arranged oppositely. The head of the rotating shaft is rotatably mounted with a clamping head for clamping the circuit board. The clamping head includes a seat body, a mandrel and a movable clamping plate. A fixed clamping plate is arranged on the seat body, and the fixed clamping plate is connected to the seat body as a whole to form an L shape. The mandrel vertically penetrates the fixed clamping plate and is slidably connected to the fixed clamping plate. A pressure cap is arranged on the top of the mandrel, and a spring is arranged between the pressure cap and the seat body. In this technical solution, the clamping head can be used to realize the rapid clamping and fixing of the circuit board; the clamping head can be quickly flipped while maintaining the clamping state, thereby realizing the rapid flipping of the circuit board, thereby improving the welding efficiency of the circuit board.

[0007] However, the circuit board welding tool disclosed above still has the technical problem of insufficient clamping convenience. Specifically, although the circuit board welding tool disclosed above can realize the rapid clamping and fixing of the circuit board; and when welding the back side of the circuit board, there is no need to loosen the clamping of the circuit board, and the circuit board only needs to be flipped. However, when clamping the circuit board, the operator needs to manually lift the circuit board and the components to be welded so that the clamping head can realize the rapid clamping and fixing of the circuit board; and in the process of the operator lifting the circuit board, the circuit board is easily deviated from the clamping position of the clamping head due to factors such as manual shaking, thereby causing the clamping surface of the circuit board to be tilted or unstable, affecting the convenience of clamping.
