Problems solved by technology

However, this method has many disadvantages
On the one hand, the tin wire is directly transported to the soldering head, and it is easy to cause waste of tin wire in the process of adding tin; on the other hand, due to the direct tin addition, the molten solder may flow to other places, making the welding quality cannot be guaranteed

Embodiment Construction

[0027] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] This embodiment relates to the improvement of the existing tin welding method. The improved welding method not only does not cause the waste of tin wire, but also can pre-detect the welding quality of the solder joint after the welding is completed, which greatly improves the soldering quality. work efficiency.

[0029] Specifically, the welding method of this embodiment is realized by welding equipment, see figure 1 As shown, the welding equipment includes a welding machine 1, a machine head 2, a welding head 3, a tinning mechanism 4 and an image mechanism 5, where the welding machine 1 is a DC inverter welding machine or an AC welding machine, which can provide 0-10V, The power supply of 0-3000A can make the welding head 3 heat up rapidly. The above welding methods specifically include:

[0030] (1) Move the welding head 3 of the w...

Abstract

The invention discloses a tinning welding method, which includes: (1) moving the welding head to the top of the solder, driving the welding head down and covering the solder; (2) heating the welding head to melt the solder and adhere to the welding head , then stop heating; (3) drive the welding head up after cooling the welding head, and move the welding head to the position to be welded; (4) drive the welding head down and cover the position to be welded, heat the welding head and melt the solder, and then stop Heating and cooling the welding head; (5) After the solder is solidified, drive the welding head up to draw the mold and heat the welding head again to realize the separation of the welding head and the solder joint. In the tin-adding welding method of the present invention, the waste of tin wire can be avoided by directly transferring the welding head to the tin wire for quantitative tin extraction; at the same time, after the welding is completed, the welding head is drawn upward after the solder is solidified, and at the solder point Applying a pre-tensioning force can well detect the firmness of the welding, thereby indirectly verifying the welding tension of the solder joints and ensuring the welding quality.

Description

technical field [0001] The invention relates to the field of photovoltaic module production, in particular to a tinning welding method for a junction box. Background technique [0002] The junction box is the current transfer station between the solar cell module and the external circuit. It is glued to the back plate of the module through silica gel. The lead wires in the module are connected to the internal circuit of the junction box, and the internal circuit of the junction box is connected to the external cable. , so that the component and the external cable are conducted to realize the function of current transfer. Since the junction box and the internal circuit are connected by soldering, the firmness of the welding is very important to the quality of the components. If there is a false weld, it will cause the junction box to heat up, break the circuit and other faults. In severe cases, the junction box will be burned and cause a fire, causing failure. recovered loss...
