Description

Technical Field

[0001] This utility model relates to wire harness connector manufacturing technology, and in particular to a wire harness connector crimping block assembly device. Background Technology

[0002] In the production of wire harness connectors, the assembly of the crimping blocks and the connector housing, as well as subsequent soldering processes, are crucial steps determining product quality. Currently, the industry largely employs a decentralized processing model of "manual feeding + semi-automatic crimping + independent soldering," which presents the following technical problems:

[0003] Low assembly efficiency and poor positioning accuracy: The pressure blocks are small in size and numerous. When relying on manual placement of the pressure blocks into the housing assembly position, the feeding is prone to misalignment due to operator fatigue, resulting in large positioning errors that directly affect the subsequent pressing and fitting. At the same time, the manual feeding capacity is low and it is difficult to meet the needs of mass production.

[0004] Poor connection of welding process: The semi-finished products after pressing need to be manually transferred to the welding equipment. During the transfer process, the pressing blocks are prone to displacement; and there is a lack of positioning structure that matches the pressing station during welding.

[0005] In view of the shortcomings of the existing technology, there is an urgent need to design an assembly device that can realize the integrated operation of "feeding-positioning-pressing-welding" and solve the problems of positioning accuracy, press-fitting stability and welding quality. Utility Model Content

[0006] The purpose of this invention is to overcome the defects of low efficiency, poor positioning, and unstable pressing and welding quality in the existing technology, and to provide a wire harness connector crimping block assembly device.
