Problems solved by technology
During this process, the nozzle 6' is directly aimed at the circuit board, its diameter is small, and it is easy to be blocked by flux crystallization, which affects the spraying operation. Therefore, it needs to be cleaned frequently, which seriously reduces the production efficiency
Moreover, the above-mentioned device directly controls the injection action through the air source, which has slow response speed, poor controllability, low precision, and poor structural installability, which is not convenient for supporting installation

Embodiment Construction
[0025] Such as Figure 2 to Figure 4 As shown, the wave soldering flux precision injection system of the present invention includes an upper gland 1 , a magnetic core seat 2 , a liquid storage chamber 4 and a nozzle seat 5 which are sequentially connected together from right to left. The upper gland 1 is provided with an electrical connector 14 for external power supply equipment. The electromagnet 13 in the magnetic core holder 2 is connected with an electrical connector 14 . The liquid storage chamber 4 is externally connected to the liquid inlet pipe 3, which reduces redundant pipe connections and sealing rings, and increases reliability. The liquid inlet pipe 3 is externally connected with flux supply equipment and compressed air supply equipment, which is convenient for inputting flux and compressed air, and the flux is sprayed out through the compressed air, and the working air source is convenient to obtain. At the same time, the liquid inlet pipe 3 communicates with ...

A precise wave-soldering flux spraying system comprises an upper gland, a magnetic core base, a liquid storage chamber and a nozzle base which are connected in sequence, wherein an electrical connector externally connected with power supply equipment is arranged on the upper gland, an electromagnet in the magnetic core base is connected with the electrical connector, the liquid storage chamber isexternally connected with a liquid inlet pipe, a cavity is formed in the middle of the liquid storage chamber, a striker assembly capable of moving back and forth along a straight line in the liquid storage chamber is arranged in the cavity, a nozzle is arranged on the nozzle base, and a sealing piece is arranged at the end of the striker assembly and used for blocking a liquid outlet of the nozzle. The precise wave-soldering flux spraying system is high in response speed, high in controllability, simple in structure and convenient to disassemble, assemble and maintain.
Description
technical field [0001] The present invention relates to a jetting device for jetting liquid or other fluids from two or more sources, and more particularly to a precision jetting system for wave soldering flux. Background technique [0002] Wave soldering flux is a chemical substance that can help and promote the soldering process in the wave soldering process, and at the same time has a protective effect and prevents oxidation reactions. Welding material surface tension", "removing oil stains on the surface of the welded material, increasing the welding area", "preventing re-oxidation", etc., there are two key roles in these aspects: "removal of oxides" and "Reduce the surface tension of the material being welded". The main function of the wave soldering flux injection system is to evenly spray rosin flux on the printed circuit board, so the quality of the injection system directly affects the soldering quality of the circuit board. [0003] At present, there are three co...
