Description

Technical Field

[0001] The utility model belongs to the technical field of flexible circuit board production, in particular to a light source detection device for a flexible circuit board. Background Art

[0002] Flexible circuit boards are one of the most common circuit boards at this stage. They are made of flexible insulating substrates. The formed flexible circuit boards are soft and can be folded and bent, making them suitable for a wide range of applications. However, they also need to be tested after production to ensure the completeness of the functions of the formed flexible circuit boards.

[0003] A Chinese patent application (or patent) with announcement number CN217901578U discloses a display touch flexible circuit board inspection platform, including a frame, a driving mechanism installed on the top of the frame, a placement mechanism installed on the bottom of the driving mechanism, a detection mechanism installed inside the frame, the detection mechanism including a shell, the inner bottom of the shell is fixedly connected to a light source, the top of the shell is fixedly connected to a second transparent plate, the inner side wall of the shell is provided with a slide groove, and the inside of the slide groove is movably connected to a control plate; when in use, the circuit board to be inspected is placed inside the placement chamber, and under the action of the light source, light will be emitted to illuminate the control plate, thereby forming a projection on the circuit board inside the placement chamber. By comparing the circuit board with the projection, it is possible to quickly detect whether there are problems such as punching offset and missed punching on the circuit board. Compared with conventional inspection platforms that require multiple instruments to be used in conjunction, this device can accurately and quickly inspect the circuit board.

[0004] The aforementioned display touch flexible circuit board inspection platform is equipped with an inspection mechanism. The inspection mechanism uses a light source to emit light. This light is transmitted through a reference plate onto the flexible circuit board to achieve a comparison inspection effect. However, different types of flexible circuit boards have different surfaces. Using the light transmission comparison effect requires the inspector to look directly at the light source, which in turn places a great strain on the operator's eyes. In addition, when using the light source in the inspection mechanism and the reference plate for comparison inspection, the operator needs to pick up and place the flexible circuit board to be inspected back and forth during operation, which is not conducive to batch production. To this end, we provide a light source inspection device for flexible circuit boards to solve the above-mentioned problems. Utility Model Content
