FFC (Flexible Flat Cable) dimension check device

[0017] Example 1:

[0018] Such as figure 1 As shown, a specific embodiment of the present invention is an EK inspection machine, including a single-axis sliding table 4, the single-axis sliding table 4 is provided with a sensor induction sheet mounting plate 6, the sensor induction sheet mounting plate 6 can be installed on the stepping motor 7. Move along the length direction of the uniaxial sliding table 4 through the lead screw under the action of.

[0019] The "E" and "K" referred to by the EKFFC size inspection device are Hitachi's E and K dimensions for products, and "E" and "K" are Hitachi's internal definition codes for FFC product shape parameters.

[0020] A first camera mounting plate 1 is provided on the sensor sensing sheet mounting plate 6, and a first camera 2 for photographing the strip is bolted to the first camera mounting plate 1. Since the sensor mounting plate 6 can be moved along the length of the uniaxial sliding table 4 through the lead screw under the action of the stepping motor 7, the first camera 2 can slide along the single axis under the drive of the sensor mounting plate 6. The length of the stage 4 moves. Before starting work, as long as the relevant product parameters are input, the first camera 2 will automatically move to the working position according to the preset program.

[0021] The side of the first camera mounting board 1 close to the stepping motor 7 is further provided with a second camera mounting board 3 and a fixed camera mounting block 8 at intervals.

[0022] The fixed camera mounting block is fixedly connected to the single-axis sliding table 4, the second camera mounting plate 3 is fixedly connected to the fixed camera mounting block 8, and the second camera mounting plate 3 is bolted to a second camera 5 for shooting the material strip.

[0023] The first camera 2 and the second camera 5 are respectively provided at the lower corners of the first camera mounting board 1 and the second camera mounting board 3 opposite to each other.

[0024] After the FFC incoming material is transferred to the inspection window of the inspection machine, the material belt stops moving, the inspection window splint 9 is tightened, and the material belt is fixed. The first camera 2 and the second camera 5 take pictures at both ends of the width direction of the material belt at the same time, and then pass a simple After data conversion and calculation, determine whether the EK size of the product is qualified.

[0025] Since the first camera 2 is a moving lens and the second camera 5 is a fixed lens, before starting work, as long as the relevant product parameters are input, the first camera will automatically move to the working position, and during the entire inspection process, the two cameras The positions are kept unchanged. Therefore, compared with the prior art, the flying time of the camera is saved during the inspection process, and the position accuracy error generated by the lead screw is also eliminated, thereby further improving the inspection accuracy of the product. Moreover, because the two images are generated and processed at the same time, the time for image analysis and calculation is also greatly reduced, which further improves the inspection efficiency of the EK inspection machine. Experimental data shows that inspection efficiency has increased by 50%.
