Equipment applied to FPC (Flexible Printed Circuit) micro-resistance automatic testing

Abstract

The invention discloses equipment applied to FPC micro-resistance automatic testing, which comprises a conveyor belt, clamping assemblies are symmetrically arranged on two sides of the conveyor belt, a lifting assembly is arranged on the two clamping assemblies, and a detection end for detecting the resistance state of an FPC circuit board is arranged on the lifting assembly. A linkage assembly for driving the clamping assembly to draw close to the inner side in the descending process of the lifting assembly is arranged between the lifting assembly and the clamping assembly, and an infrared sensor used for detecting the FPC board on the surface of the conveying belt is arranged on the lifting assembly, so that the existence of the FPC board can be automatically detected; and according to the utility model, the clamping parts are arranged on the two sides of the detection end and drive the detection end to descend for resistance detection, the linkage assembly is arranged in the descending process of the detection end, the clamping parts on the two sides clamp the FPC board, the PFC board is prevented from loosening in the detection process, the detection stability and accuracy are improved, meanwhile, one driver is arranged to realize multiple actions, the driving cost is reduced, the manufacturing cost is saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of FPC board detection, in particular to equipment applied to automatic testing of FPC micro-resistance. Background technique [0002] After the FPC circuit board is produced, resistance testing is required. It is mainly measured by a micro-resistance meter. The micro-resistance meter can measure low-resistance instruments such as circuit boards and coil internal resistance. It has a wide measurement range and can quickly sample. The traditional detection method passes Manually detect the FPC boards one by one or use the detection equipment to perform resistance detection, but because the detection equipment does not have an automatic clamping linkage mechanism, the clamping mechanism cannot be linked and clamped during the feeding process of the detection end, and cannot be automatically released after leaving, resulting in Manual clamping is required, the operation is cumbersome and the efficiency is low.

[0002] After the FPC circuit board is produced, it is necessary to perform resistance detection. The micro-resistance meter is mainly used for measurement. The micro-resistance meter can measure low-resistance instruments such as circuit boards and coil internal resistance. It has a wide measurement range and can quickly sample. The traditional detection method passes Manually detect the FPC boards one by one or perform resistance detection through testing equipment, but because the testing equipment does not have an automatic clamping linkage mechanism, the clamping mechanism cannot be linked and clamped during the feeding process of the detection end, and cannot be automatically released after leaving, resulting in Manual clamping is required, the operation is cumbersome and the efficiency is low
