Description

Technical Field

[0001] The utility model relates to the technical field of soldering equipment, and in particular to a flux-saving air knife device. Background Art

[0002] Flux air knife systems are often used on equipment that requires soldering processes, especially in the electronics manufacturing industry, especially in processes involving soldering of copper wires, cables, PCBs (printed circuit boards) and other metal components. These systems are designed to remove excess flux from the surface of metal components before soldering to ensure the quality and efficiency of soldering;

[0003] When welding copper wire or cable, when the copper wire or cable enters the high-temperature tin furnace in the welding equipment, in order to ensure that the wind knife blows off the flux on the copper wire or cable, the copper wire or cable needs to accurately pass through the center of the wind knife, and the wind knife in the prior art does not have the function of positioning the cable or copper wire. When the copper wire or cable enters the high-temperature tin furnace, the copper wire or cable is prone to position displacement, resulting in the copper wire or cable not being in the center of the annular wind knife, affecting the effect of the annular wind knife in blowing off the flux on the copper wire or cable. The position of the annular wind knife needs to be frequently adjusted, which increases maintenance costs. Therefore, a flux-saving wind knife device is designed to solve the above problems.

[0023] like Figure 1-Figure 5 As shown, the embodiment of the utility model provides that the technical problem to be solved by the utility model is to provide a flux-saving wind knife device, including an annular wind knife 1 and a bracket 2 installed on the annular wind knife 1, an internal thread 3 is provided at the right end of the central through hole of the annular wind knife 1, a guide tube 201 is provided through the center of the left side surface of the bracket 2, and an external threaded tube 202 is provided through the center of the right side of the bracket 2.

[0024] By providing a bracket, when the annular air knife 1 is installed, by installing the bracket on the soldering equipment, when the copper wire or cable with flux needs to enter the soldering equipment for soldering, the copper wire or cable first passes through the guide tube 201 on the left side of the bracket 2, and then passes through the central through hole of the annular air knife 1 and the external threaded tube 202 at the right end of the bracket 2 in sequence, and finally enters the soldering equipment for soldering. The copper wire or cable can be positioned by the guide tube 201 and the external threaded tube 202 to ensure that the copper wire or cable passes through the center of the annular air knife 1, and the annular air knife 1 blows off the excess solder resist on the copper wire or cable, which can reduce the debugging time of the air knife and reduce the maintenance cost;

[0025] The annular air knife 1 blows off the excess flux, preventing the excess flux from entering the high-temperature soldering furnace and causing tin explosion, thereby reducing potential safety hazards, reducing the generation of tin ash, reducing the amount of flux used, and improving welding quality, thereby preventing excess flux from remaining on the soldering point and affecting electrical performance and reliability.

[0026] In this embodiment, the central through hole of the annular air knife 1 is in a funnel shape with a larger diameter on the left side and a smaller diameter on the right side, so that the air in the annular air knife 1 can be discharged from the left side.

[0027] In this embodiment, the internal thread 3 matches the external threaded tube 202, and the external threaded tube 202 is threadedly connected to the internal thread 3, so that the annular air knife 1 is conveniently installed.

[0028] In this embodiment, the annular wind knife 1 includes a left ring 101 and a right ring 102. The left surface of the left ring 101 is provided with an air inlet channel 103, the right surface of the left ring 101 is provided with an umbrella-shaped groove 104, an umbrella-shaped block 105 is fixedly provided in the center of the left surface of the right ring 102, and a sealing ring 106 is fixedly provided on the outer side of the left surface of the right ring 102, and the sealing ring 106 is fixedly provided on the right surface of the left ring 101.

[0029] In this embodiment, the air inlet channel 103 runs through the umbrella-shaped groove 104 , so that an external air source can be easily charged into the umbrella-shaped groove 104 through the air inlet channel 103 .

[0030] In this embodiment, the umbrella-shaped groove 104 matches the umbrella-shaped block 105, and when the sealing ring 106 is fixed on the left ring 101, there is a gap between the umbrella-shaped groove 104 and the umbrella-shaped block 105, which facilitates the wind entering the air intake channel to blow into the central through hole of the annular wind knife 1 from the gap between the umbrella-shaped groove 104 and the umbrella-shaped block 105.

[0031] By providing the umbrella-shaped groove 104 and the umbrella-shaped block 105, the external air source enters the gap between the umbrella-shaped groove 104 on the left ring 101 and the umbrella-shaped block 105 on the right ring 102 from the air inlet channel 103 and enters the central through hole of the annular air knife 1. The gap formed by the umbrella-shaped groove 104 and the umbrella-shaped block 105 guides the wind blown into the central through hole of the annular air knife 1 to the left, so that the wind blown out by the annular air knife 1 can blow the excess solder resist adhered to the surface of the copper wire or cable passing through the annular air knife 1 to the left, further increasing the effect of blowing off the flux.

[0032] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model.
