Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic component welding, in particular to a soldering flux pen for reworking of photovoltaic components. Background Art

[0002] Photovoltaic module welding is a very complex process used to connect two materials without fusing them. The main function of flux is to remove oxides on the surface of solder and the base material to be welded, so that the metal surface reaches the necessary cleanliness, prevents re-oxidation of the surface during welding, reduces the surface tension of the solder, and improves welding performance. The quality of flux performance directly affects the quality of the product.

[0003] The flux pen is used to apply flux on the metal surface before the soldering process. The main advantage of using a flux pen is that you only need to apply flux to the area where soldering is required. The mainstream products on the market are disposable and have a high cost of use; therefore, in order to solve this problem, it is necessary to improve the existing technology, and the utility model comes into being. Utility Model Content

[0004] The utility model aims to provide a soldering flux pen with replaceable soldering flux liquid to solve the above-mentioned problems mentioned in the background technology.

[0006] A soldering flux pen for reworking a photovoltaic module, the soldering flux pen comprising: a pen tube, a pen head, and a pen core, the pen head is located between the pen tube and the pen core, and the pen core is inserted into the pen head;

[0007] The pen tip has a cavity inside, namely a first cavity and a second cavity. The first cavity has a central opening, which is connected to the bottom of the pen core in the central hole of the first cavity. A sealing plug is provided between the first cavity and the second cavity, namely the sealing plug divides the inside of the pen tip into two cavities. A spring is provided in the second cavity.

[0008] One end of the sealing plug is connected to the pen core, and the other end of the sealing plug is connected to the spring in the second cavity; the bottom end of the spring is fixed inside the pen tube; in a normal non-pressed state, the first cavity and the second cavity are separated, and the flux is blocked in the pen tube; when the pen core is pressed, the first cavity and the second cavity are connected, and the flux enters the second cavity and then flows to the pen core, and the pen core absorbs the outflowing flux and coats it on the substrate to be welded.

[0009] Furthermore, the pen core is a flat structure, and the bottom connected to the pen tip is cylindrical, the head of the pen tip is flat, and the pen core is pluggable and connected to the inside of the pen tip. As long as the size of the plug-in and pull-out parts of the pen core and the pen tip is fixed, the front end of the pen core can be designed with different types of appearances, including bullet shape or chisel shape.

[0010] Furthermore, the pen tube is a cylindrical structure, including two glass beads, the head of the pen tube and the pen tip can be separated, and the bottom can also be unscrewed and separated. The glass beads play a role in mixing the flux, and shaking it when using it accelerates the mixing.

[0011] The beneficial effects of the utility model compared with the prior art are:

[0012] (1) By improving the refill structure, the refills with different shapes and sizes of the head can be replaced, so that the area of ​​flux coating can be accurately controlled to ensure the cleanliness of the welding area, and it can be applied to welding conditions of different areas;

[0013] (2) Easy to operate, the pen-shaped size is also convenient to carry, and the pen core can temporarily store the flux liquid to prevent leakage;

[0014] (3) The valve of the flux pen adopts the pressing principle, which can easily and accurately control the amount of flux applied;

[0015] (4) It is easy to clean. Since each flux formula is different, avoid mixing. Before changing the flux manufacturer, you need to clean the entire flux pen. All parts of the structure can be separated for easy cleaning. The glass ball can also make the flux mix evenly. BRIEF DESCRIPTION OF THE DRAWINGS
