Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of automobile new energy capacitors, in particular to a kind of automobile new energy capacitor welding positioning fixture of electrode of its capacitor inner core group is led out on automobile new energy capacitor. BACKGROUND

[0002] With the development of new energy vehicles, the demand for automobile new energy capacitors applied to new energy vehicles is also increasing. However, due to the large capacity and high current characteristics of automobile new energy capacitors, it is determined that automobile new energy capacitors usually use multiple large-capacity capacitor cores to arrange and combine and through copper bars to lead out the capacitor core electrodes. In order to improve the heat dissipation efficiency, multiple capacitor cores are arranged at a certain interval distance, and then the electrode copper bars (or large current lead-out ends) are welded and led out. This increases the difficulty of electrode copper bar (or large current lead-out end) lead-out welding positioning operation of capacitor core. The existing technology usually uses capacitor packaging shells to weld and lead out electrodes. Due to the complexity of the structure of the electrode copper bar (or large current lead-out end), it is difficult to operate the welding and positioning with the capacitor packaging shell. Some packaging shells and electrode lead-out structures also cannot be operated with the shell welding, which makes the welding and positioning operation more difficult and the welding and positioning efficiency is low.

[0003] The authorized patent number ZL202021925606.3, announced on May 14, 2021, discloses a kind of automobile electric drive capacitor core welding clamping device, including bottom plate, first shaft, storage box, push screw and buffer mechanism;The top of the bottom plate is fixedly installed with an operation table through a manual telescopic mechanism, one side of the top of the bottom plate is fixedly installed with a first side plate, the central position of the first side plate is fixedly installed with a first shaft through a bearing, the other side of the top of the operation table is fixedly installed with a second side plate, the central position of one side of the second side plate is fixedly installed with a second shaft through a bearing, and the central position of the other side of the second side plate is fixedly installed with a storage box. By setting the buffer mechanism, when the person twists the push screw to move the concave clamping plate to clamp and fix the core, the buffer mechanism can buffer the pushing force to avoid the concave clamping plate moving too much caused by the push screw, which can damage the core. Although this scheme can realize the welding and clamping of the automobile electric drive capacitor core, it is difficult to solve the above-mentioned positioning and welding effectiveness of the automobile new energy capacitor core.
