Connecting box bus bar welding machine and welding detecting method thereof

Abstract

The invention provides a connecting box bus bar welding machine and a welding detecting method thereof. The connecting box bus bar welding machine comprises a welding part, a loading part and a conveying mechanism, the welding part is located at the upper portion of the loading part, and the conveying mechanism is located on the side edge of the loading part; the welding part comprises a support, and a horizontal-vertical conveying mechanism is arranged on the support and is provided with a welding mechanism; by means of the welding machine, three-axis positioning is matched with a CCD camera, automatic alignment is achieved, and the automatic degree is improved; in addition, the connecting box bus bar welding machine is more accurate in alignment compared with a traditional machine, a temperature sensor and a pressure sensor are arranged on a welding head, tight contact between the welding head and a welding wire is guaranteed by downwards pressing the welding head, welding is accurate, automatic lifting is carried out after corresponding temperature and pressure values are obtained, and the welding stability is guaranteed.

Description

technical field [0001] The invention relates to the field of automation equipment, in particular to a junction box bus bar welding machine and a welding detection method thereof. Background technique [0002] Photovoltaic modules are products that are connected and packaged by multiple photovoltaic cells. The photovoltaic module junction box is the key connection device for the solar module system. The function of the junction box is to prevent the hot spot effect when the solar module is partially blocked. If the junction box is damaged or the connection is not reliable, the junction box will not work properly, so when the solar module is partially covered, the entire solar module system will not work normally, and the covered part will emit a lot of heat, which will burn the module seriously . At present, the existing junction boxes for solar cell modules are all welded manually, the production efficiency is low, and the welding quality cannot be guaranteed. Later, some w...

Problems solved by technology

If the junction box is damaged or the connection is not reliable, the junction box will not work properly, so when the solar module is partially covered, the entire solar module system will not work normally, and the covered part will emit a lot of heat, which will burn the module seriously

At present, the existing junction boxes for solar cell modules are all welded manually, the production efficiency is low, and the welding quality cannot be guaranteed. Later, some welding equipment gradually became available, but the following problems still exist, such as the invention patent with the patent number 201410173366.9 , the disclosed junction box automatic welding machine, the position of its welding components is uncontrollable, still needs manual adjustment, its degree of automation is low, and in the existing equipment, when welding, due to the complicated structure of welding wire transmission, the equipment is large in size, and The welding head of the traditional equipment is directly welded. Due to the unevenness of the product surface, some welding heads are not pressed against the welding wire. In the end, there is no welding liquid coating, resulting in incomplete welding and other problems, and the product cannot be detected at any time after welding. welding quality
