Integrated automatic microscopic welding equipment

Abstract

The invention relates to automation of welding, in particular to integrated automatic microscopic welding equipment. Automatic welding of two weldments can be realized at the same time through two integrally-mounted spot welding machine headpieces, two horizontally-clamping welding head clamps, two spot welding power sources and an automatic spot welding power device, wherein the welding head clamps are arranged at the same horizontal position side by side; welding parameters of two parallel electrode welding heads are independently adjusted to guarantee welding reliability and uniformity. Through improvements of frames of the spot welding machine headpieces, gaps between the horizontally-clamping welding head clamps which are arranged at the same horizontal position side by side can be adjusted. The brand-new automatic welding equipment is provided for production of electronic components.

[0002] The CN1382557 patent announced by the Chinese Patent Office on December 4, 2002 discloses a double welding head spot welding machine, which mainly improves the welding head clamp, and the purpose is to optimize the welding effect, and the double welding head spot welding machine is theoretically Obviously, it can improve the efficiency of spot welding. However, the double welding head spot welding machine disclosed in the CN1382557 patent cannot independently adjust the electrode force of each parallel electrode and the electrical parameters of the welding energy output. Therefore, How to make the spot welding machine with double welding heads not only improve the efficiency of spot welding, but also obtain more accurate spot welding effect is one of the problems to be solved urgently in the industry

[0003] Specifically, the traditional resistance welding spot welding equipment has the following characteristics: First, spot welding is performed with a single solder spot. Since most electronic components have two lead-out contacts that need to be spot-welded, therefore, equipment with multiple solder spots The spot welding machine will be able to provide higher spot welding efficiency; Second, the accuracy of the electrode force at the traditional resistance point can reach ±10N, while the electrode force commonly used in practice generally only needs to be below 10N, so the electrode force achieved by the traditional technology The accuracy cannot meet the requirements of spot welding

It can be seen that the spot welding machine is a kind of precision equipment, and the spot welding machine with multiple welding points is more difficult to grasp due to the further complexity of its structure, such as the overall weight of the machine head and the increase in power during operation.
