Embodiment 1

[0027] see Figure 1 to Figure 5 , the present embodiment provides a device for spraying flux with precise control of the amount applied. At least one water pump 3 is provided, and at least a filter 4 is provided on the conduit 2. The liquid outlet 11 of the conduit 2 is provided with a spray head 5. The spray head 5 includes a fixed head 51 and a needle 52, and the needle 52 is fixed on the fixed head. The needle 52 has a diameter of 0.16 mm, and a switch 21 is arranged on the catheter 2 .

[0028] continue to see Figure 1 to Figure 5 , one end of the conduit 2 located at the shower head 5 is provided with a flow meter 22 . The flow of flux can be monitored at any time to ensure the use of the device, avoid affecting product quality due to insufficient flux, and reduce unnecessary losses.

[0029] continue to see Figure 1 to Figure 5 , the liquid outlet of the conduit 2 has an internal thread. The fixing head 51 is provided with an external thread matching the internal...

Embodiment 2

[0037] see Figure 1 to Figure 5 , the figure shows a flux spraying device with precise control of the application amount provided by Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, this embodiment further makes the following technical solutions as improvements: needle The diameter of 52 is 0.11mm, 0.12mm, 0.18mm, etc., and the diameter of needle 52 in this implementation is 0.16mm. Can achieve the best spray flux effect.

Embodiment 3

[0039] see Figure 1 to Figure 5 , the figure shows a device for spraying flux with precise control of the application amount provided by Embodiment 3 of the present invention. On the basis of the above-mentioned embodiments, this embodiment further makes the following technical solutions as improvements: Conduit Two water pumps 3 are arranged on 2, and two filters 4 are also arranged on the conduit 2, and the two filters 4 are located between the two water pumps 3. Through the setting of the above structure, the functional failure caused by the blockage caused by foreign matter or other factors can be effectively prevented, and the cleanliness of the flux can be effectively maintained for a long time, and the water pump is added to ensure sufficient pressure to prevent fine-diameter blockage.

Abstract

The invention provides a soldering flux sprinkling device capable of accurately controlling an applying amount. The device comprises a liquid storing groove which is provided with a liquid outlet; a guide pipe is arranged on the liquid outlet, and is provided with at least one water pump; the guide pipe is further provided with at least a filter; the liquid outlet of the guide pipe is provided with a sprinkling head; the sprinkling head comprises a fixing head and a needle head; the needle head is fixed in the fixing head and extends out of the fixing head; the diameter of the needle head is 0.1 mm to 0.2 mm; and a switch is arranged on the guide pipe. According to the soldering flux sprinkling device capable of accurately controlling the applying amount, by reducing the caliber of the sprinkling head, the soldering flux sprinkling area can be reduced, the soldering flux sprinkling position can be flexibly controlled, the position without needing soldering flux sprinkling is effectively avoided, and therefore the after-welding loss abnormity problem caused by soldering flux is solved.

Description

technical field [0001] The invention relates to a flux spraying device, in particular to a flux flux spraying device with precise control of application amount. Background technique [0002] Flux is usually a mixture of rosin as the main component, which is an auxiliary material to ensure the smooth progress of the soldering process. Welding is the main process in electronic assembly. Flux is an auxiliary material used in welding. The main function of flux is to remove the oxides on the surface of the solder and the base material to be welded, so that the metal surface can reach the necessary cleanliness. It prevents The re-oxidation of the surface reduces the surface tension of the solder and improves the soldering performance. The performance of the flux directly affects the quality of electronic products. [0003] It is difficult to control the application amount, application position and adjustment flexibility of the existing flux spraying device, and it is impossible t...
