A PCBA functional testing device for automotive lamp assembly

Abstract

This utility model discloses a PCBA functional testing device for automotive lamp assembly, relating to the field of PCBA testing technology. It includes a testing structure located on the top of a housing, with a locking block structure on one side. A lifting platform structure for fixing the PCBA is fixedly connected at its top to a crank lifting structure, and a positioning seat structure is located at the bottom of the lifting platform structure. The positioning seat structure includes a positioning base with a placement groove at its top. When the push plate pushes the moving plate close to the connector, multiple test pins at both ends of the moving plate can be inserted into the connector and contact the contacts inside, enabling normal testing. A slider, in conjunction with a slide rail, ensures the moving plate remains stable during movement, preventing tilting when inserting or removing test pins and maintaining consistent force during insertion and removal, thereby preventing damage to the contacts inside the connector.

Description

Technical Field

[0001] This utility model relates to the field of PCBA testing technology, specifically a PCBA functional testing device for automotive lamp assembly. Background Technology

[0002] Automotive lighting PCBA refers to the printed circuit board assembly of automotive lighting fixtures. It is the core part of the automotive lighting system, undertaking important functions such as power distribution, signal transmission, and light control. Automotive lighting PCBA needs to have characteristics such as high reliability, good heat dissipation performance, and precision manufacturing. It is mainly used in headlights, taillights, and other vehicle lights.

[0003] When assembling a PCBA with automotive lights, the connector must first be assembled with the PCBA. After the PCBA and connector are assembled, the contacts inside the connector are located inside the connector, which causes some contacts to be blocked. Because the connector contacts are located inside the connector and the connector surface is not flat, traditional PCBA testing equipment cannot be used for testing. Therefore, the testing of PCBA connectors is generally done manually. That is, the operator manually inserts the test probe into the connector to make contact with the connector contacts, and then manually pulls the test probe out after the test is completed. However, when manually inserting and removing the test probe, the connector contacts may be damaged due to excessive force or tilting of the force applied by the operator. In addition, the efficiency of manual testing is also low. Utility Model Content
