Description

Technical Field

[0001] The utility model relates to the technical field of automatic soldering flux replenishing tanks, in particular to an automatic soldering flux replenishing device. Background Art

[0002] In the electronic manufacturing, metal welding and other industries, flux is a widely used auxiliary material. The main function of flux is to remove oxides on the welding surface, reduce welding temperature and improve welding quality. However, in the actual production process, the addition of flux often depends on manual operation, which not only increases the labor intensity, but also easily leads to inaccurate addition amount due to human factors, thus affecting the welding quality. The existing flux adding device can only perform simple quantitative addition and cannot adjust the addition amount in real time according to welding requirements. Utility Model Content

[0007] Preferably, fixing plates are fixedly installed on both sides of the centrifugal pump, and multiple groups of screw holes are provided on the outer surface of the fixing plates. The fixing plates and screw holes enable the centrifugal pump to be securely installed in an appropriate position, and the screw holes enable the centrifugal pump to be conveniently installed on any fixed structure that matches the screw holes, which also facilitates subsequent maintenance and replacement.

[0008] Preferably, an observation window is provided on the outer surface of the storage tank, which allows the operator to directly observe the liquid level of the flux inside the storage tank without opening the storage tank or relying on other detection tools, thereby helping to promptly detect liquid level changes and ensure timely replenishment of the flux.

[0009] Preferably, a spare pipe is fixedly installed on the outer surface of the feed pipe, and a manual valve is provided on the outer surface of the spare pipe. When the main feed pipe or the electronic valve fails, the spare pipe and the manual valve can be used as emergency measures to ensure a continuous supply of flux, thereby increasing the reliability of the entire system and reducing the risk of system shutdown due to a single failure point.

[0010] Preferably, a cavity is formed on the inner wall of the storage tank, and a plurality of heating tubes are arranged inside the cavity.

[0013] It can be seen from the above technical solutions that the present application has the following beneficial effects:

[0014] 1. The utility model can accurately grasp the liquid level of the flux in the storage tank through real-time monitoring of multiple groups of liquid level sensors. This real-time monitoring ensures timely replenishment of the flux and avoids production interruptions caused by low liquid level. The precise control of the electronic valve ensures that the flux can flow into the storage tank accurately and quickly. At the same time, the combination of the centrifugal pump and the feed pipe realizes the continuous feeding of the flux.

[0015] 2. The utility model opens a cavity through the inner wall of the storage tank, and arranges multiple groups of heating tubes inside the cavity. When the ambient temperature drops or the temperature of the flux drops, the control system can start the heating tube to quickly increase the temperature in the storage tank by heating, thereby ensuring the temperature of the flux is stable. The heating effect of the heating tube can not only effectively prevent the flux from agglomerating or solidifying, but also improve its fluidity, ensuring that the flux can flow smoothly from the discharge pipe when in use.

[0026] Furthermore, an observation window 5 is provided on the outer surface of the storage tank 1, which allows the operator to directly observe the liquid level of the flux inside the storage tank 1 without opening the storage tank or relying on other detection tools, thereby helping to timely detect liquid level changes and ensure timely replenishment of the flux.

[0027] Furthermore, a spare pipe 911 is fixedly installed on the outer surface of the feed pipe 4, and a manual valve 912 is provided on the outer surface of the spare pipe 911.

When the liquid level drops to the preset minimum threshold, the liquid level sensor will send a signal to the control system to start the automatic replenishment process.

The centrifugal pump 7 extracts the flux from an external source through the feed pipe 8 and delivers the flux to the storage tank 1 through the delivery pipe 4. In this process, the electronic valve 6 controls the on and off of the delivery pipe 4 to ensure that the flux can flow into the storage tank 1 accurately and quickly, and then be output from the discharge pipe 2.
