Problems solved by technology
When flexible circuit boards are used in display module products, there are often strict requirements for the distance between the FPC bending position and the edge of the display module cover. The general method is to manually control the distance accuracy one by one, or A 2.5-dimensional measuring instrument is used for measurement, but this method is time-consuming and laborious in practical application, which seriously reduces the production efficiency of the product

The invention discloses an auxiliary limiting detection jig for a flexible circuit board. The auxiliary limiting detection jig comprises a fixed bottom plate, and a product bottom plate is mounted onthe fixed bottom plate in parallel; a sliding piece is arranged between the product bottom plate and the fixed bottom plate; a groove is formed in the front end of the product bottom plate; a pendulumdevice is arranged at the position, corresponding to the groove in the front end of the product bottom plate, of the fixed bottom plate; an alarm device is arranged at the adjacent position of the pendulum device; a holder cushion block is arranged on the fixed bottom plate; a clamper is arranged above the holder cushion block; the clamper is used for driving the product bottom plate to translateon the sliding piece; the detection jig is designed for meeting the high-precision requirement in the manufacturing process of the flexible circuit board in a display module product; the detection jig can easily and quickly detect the product precision and whether the product is qualified, is simple in overall structure, easy to form, small and portable, avoids the great labor intensity of manualdetection, effectively saves the working hours, improves the working efficiency, can improve the detection precision, and guarantees the product quality.
Description
technical field [0001] The invention relates to the technical field of circuit board detection, in particular to an auxiliary limit detection jig for flexible circuit boards. Background technique [0002] Flexible printed circuit boards (FPC) are made by forming circuit patterns on polyimide or polyester film substrates, and are widely used in different electronic products due to their thinness and flexibility, such as notebook computers, smartphones, In electronic products such as digital cameras and display screens. When flexible circuit boards are used in display module products, there are often strict requirements for the distance between the FPC bending position and the edge of the display module cover. The general method is to manually control the distance accuracy one by one, or A 2.5-dimensional measuring instrument is used for measurement, but this method is time-consuming and laborious in practical application, which seriously reduces the production efficiency of ...
