Description

Double-electrode welding device Technical Field The utility model relates to the field of welding electrodes, in particular to a double-electrode welding device. Background In the process of welding the chip and the terminal, the conventional manner is to weld two pin pins of the chip and two pin pins of the terminal respectively. When the traditional welding electrode device is operated, the upper electrode and the lower electrode are required to be welded with one group of pin pins of the chip and the terminal, the electrode is removed after the welding is finished, and then the other group of pin pins which are moved to the chip and the terminal are welded again, so that the whole process is complicated. To solve this problem, the skilled person devised a double electrode welding device. However, the electrodes of the device do not achieve compression balance self-correction. Because the chip and the terminal have errors in the processing process, the thickness of the product cannot be ensured to be completely consistent every time, and the situation that one electrode is tightly attached to one group of pin pins and the other electrode is not attached to the other group of pin pins possibly occurs during welding. Therefore, the pre-pressing pressure of the electrode to the pin is unbalanced, so that welding current is split, and finally, failure phenomena such as poor welding effect, unqualified welding pull-out force of a weldment and the like are caused. For example, a weld pull resistance of only 44N may occur for one set of pin pins, while a acceptable weld pull resistance should be 75N or more. The welding tensile resistance refers to the maximum tensile force which can be born by the welding joint when the welding joint bears the action of axial tensile load, and the welding tensile resistance is taken as a key mechanical property index for measuring the welding quality, so that the tensile failure resistance of the welding joint can be intuitively reflected. Disclosure of utility model The utility model aims to solve the technical problem that the electrode in the existing double-electrode welding device cannot realize the self-correction of the compaction balance. The utility model provides a double-electrode welding device, wherein a first electrode and a second electrode have automatic adjustment capability, and the self length of the outer part of a shell can be dynamically adjusted according to actual working condition requirements. The first electrode and the second electrode are ensured to be in close contact with the workpiece, the welding current is ensured to be uniform, and the tensile resistance of the workpiece is improved. To solve the above technical problems, an embodiment of the present utility model discloses a dual electrode welding device, including: A housing including a receiving cavity; The length adjusting part is arranged in the accommodating cavity and can rotate around a first fulcrum relative to the accommodating cavity by taking a first direction as an axial direction; A first electrode carrier in contact with one end of the length adjustment section; The second electrode carrier is in parallel with the second electrode carrier along a second direction, the second electrode carrier is in contact with the other end of the length adjusting part, and the second direction is perpendicular to the first direction; The first electrode is arranged in the first electrode carrier, one end of the first electrode is connected with the first electrode carrier, the other end of the first electrode extends out of the shell, the first electrode can be driven by an external structural member to move along a third direction relative to the shell, and the third direction is perpendicular to the first direction; The second electrode, the one end of second electrode is located in the second electrode carrier, and with the second electrode carrier is connected, the other end of second electrode stretches out the shell, the second electrode can be driven by external structure along the third direction is relative the shell removes, the direction of movement of second electrode is opposite with the direction of movement of first electrode. In the processing links of the chip and the terminal, certain processing errors are inevitably generated by two first pin feet of the chip and two second pin feet of the terminal due to the complexity and limitation of the process. Such errors result in the inability to ensure that the thickness of the first pin and the second pin remain consistent during each production process. One first pin of the chip and one second pin of the terminal are a first pin group, and the other first pin of the chip and the other second pin of the terminal are a second pin group. By adopting the technical scheme, taking the thickness of the first pin group is smaller than that of the second pin group as an example, when the second electrode contacts the second pin group with
