With the increasing demand for efficiency and production capacity in the automotive manufacturing industry, traditional manual testing can no longer meet the needs of large-scale production. Against the backdrop of the rapid development of new energy vehicle manufacturing, testing forms and connection methods are constantly upgrading.
The most common form of automated testing is to pre install the tested unit on a tray and then transport it to the testing station for testing interconnection. Previously, a single workstation testing system with two pallets was used for small-scale production, which resulted in low efficiency and low production capacity in single loop testing.
In order to increase the testing production line and improve capabilities, the number of testing stations has been increased, and nearly 100 trays have been added, in order to expand production capacity and achieve the goal of automated testing. By adopting rotary automation testing, the electrical, gas, liquid and other signals in the tested unit are concentrated on the tray quick connector, which automatically connects with the rack connectors of each testing station, thus realizing a multi loop automatic testing production line.
On such a multi loop automated testing assembly line, dozens of trays are operated on the assembly line, matched and docked with multiple testing stations, and different testing projects are executed. Therefore, the interchangeability and compatibility of tray and bench combination connectors are particularly important.
The connector between the tray and the rack meets the following requirements
Modular and multi combination: One testing line is used to test multiple products, and individual components need to be quickly replaced and expanded to achieve rapid testing of different types.
Correction of docking deviation: More than ten pallets are operated in a streamlined manner on the body, matched and docked with multiple testing stations, and different testing projects are executed. Therefore, it is necessary to ensure the safety and reliability of each cross station docking
High lifespan plugging and unplugging: Each testing station can meet thousands of docking times per month (calculated based on production capacity), so the connectors at the station end need to meet 100000 plugging and unplugging times
Small size and compact space: The installation space for trays and testing stations on the testing line is very compact, requiring side installation
