A multi-purpose automatic spot welding device

Abstract

The invention provides a multifunctional automatic spot-welding device. The multifunctional automatic spot-welding device is characterized by comprising a welding joint fixture driven to lift by a welding cylinder, wherein the welding joint fixture is provided with a plurality of press-type telescopic ejection rods which are arranged in the form of an array, a plurality of welding joints and a push plate; one end of each of the plurality of ejection rods is fixed on the push plate, one welding joint is fixed at the other end of each of the plurality of ejection rods, each welding joint comprises a rod fixation part and a welding part rotationally connected to the fixation part, the fixation part and the welding part are provided with matched thread holes at a hinge point, and after rotation of each welding part, a fastener penetrates through the two corresponding thread holes to fix the welding part on the corresponding fixation part. According to the invention, one welding joint fixation can be applied by being matched with a plurality of welding machine types, and one welding joint can be applied by being matched with at least two welding pads with different sizes; the multifunctional automatic spot-welding device is simple in structure, convenient to operate and fast in welding; welding spots are fully filled with tin, uniform in size, and high in consistency; and after the multifunctional automatic spot-welding device is used, the efficiency and quality of junction box patch production can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of patch production of photovoltaic junction boxes, and in particular relates to a multi-purpose automatic spot welding device. Background technique [0002] Almost all electronic, electrical products and electromechanical products need to use junction boxes. The junction box patch production line is to sequentially perform processes such as spot soldering, spotting red glue, and patch diodes on the copper substrate. Spotting solder on the copper substrate is wiring. In the second process of box patch production, the efficiency of tin spot directly affects the efficiency and quality of patch production. At present, there is a station in the production of junction box patches. Manually hold the welding head in one hand and the solder wire in the other hand to weld the soldering points on the copper substrate. The manual welding efficiency is low, and the size and fullness of the soldering points are unstable....

Problems solved by technology

At present, there is a station in the production of junction box patches. Manually hold the welding head in one hand and the solder wire in the other hand to weld the soldering points on the copper substrate. The manual welding efficiency is low, and the size and fullness of the soldering points are unstable. Affect the efficiency and quality of patch products

[0003] In addition, the industry also attempts to replace traditional manual spot welding with automatic spot welding, and completes automatic spot welding by driving the welding head with a cylinder or lifting the welding head tooling with several welding heads. However, on the one hand, the existing welding head Tooling can only be used for one type of welding machine. On the other hand, the existing welding head can only be used for welding points of one pad size, which will also affect welding efficiency and welding quality during use.
