[0030] In addition, the terms "horizontal", "vertical", "overhanging", etc. do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0033] like Figure 1 As shown, a flexible circuit board detection device comprises a base 1, a conveying tray 2 arranged above the base 1, a plurality of slots 3 uniformly penetrated and opened along the circumferential direction of the conveying tray 2 and with the opening direction facing outward, a clamping mechanism 4 respectively arranged in the slots 3, a driving mechanism 5 connected between the conveying tray 2 and the base 1 and used for driving the intermittent rotation of the conveying tray 2, two groups of detection components 6 symmetrically arranged at the upper and lower ends of any one of the slots 3, and an adjusting component 7 for adjusting the distance between the two groups of detection components 6 and the slots 3.

[0034] In practice, the flexible circuit board is clamped and fixed on the clamping mechanism 4 in the slot 3 in sequence. During the fixed clamping process, the distance between the two groups of detection components 6 and the slot 3 can be adjusted by adjusting the component 7, so that the device can adapt to the detection needs of flexible circuit boards of different sizes. The driving mechanism 5 drives the conveyor disc 2 to rotate intermittently, so that the flexible circuit board can be rotated to the position of the detection component 6 one by one according to the preset sequence. The detection components 6 are symmetrically arranged at the upper and lower ends to simultaneously detect the images of the front and back sides of the flexible circuit board. After the detection is completed, the flexible circuit board is rotated out of the detection mechanism as the conveyor disc 2 rotates, thereby facilitating the unloading of the flexible circuit board. The device of the utility model has a simple structure and is easy to operate, which can effectively improve the efficiency and accuracy of detection, thereby ensuring product quality and reliability.

[0036] The working principle of the driving mechanism 5 is as follows: the driving motor 13 drives the driving wheel 10 to rotate, so that the sliding column 11 eccentrically arranged on the upper end surface of the driving wheel 10 moves in the sliding groove 9, thereby driving the driven wheel 8 and the conveying disc 2 fixed above the driven wheel 8. When the sliding column 11 slides out of the sliding groove 9, the driven wheel 8 no longer rotates until the sliding column 11 rotates into the sliding groove 9 again, and the driven wheel 8 and the conveying disc 2 continue to rotate, realizing the intermittent rotation of the conveying disc 2, which is convenient for the detection and loading and unloading of flexible circuit boards.

[0037] like Figure 1 and Figure 3 As shown, a groove 15 is provided on the side wall of the notch 3 opposite to its opening, and the clamping mechanism 4 includes: a first bidirectional screw rod 16 rotatably connected at both ends to the groove 15, a moving block 17 threadedly connected to both ends of the first bidirectional screw rod 16 and slidably connected to the groove 15 at the upper and lower end surfaces, a driving member driving the first bidirectional screw rod 16 to rotate, and clamping members respectively connected to the moving block 17.

[0040] During use, when it is necessary to adjust the clamping width of the clamping mechanism 4, the hand wheel 21 is turned to drive the rotating shaft 20 to rotate, thereby driving the second gear 19 at the end of the rotating shaft 20 to rotate, thereby driving the first gear 18 meshing with the second gear 19 to rotate, and then driving the first bidirectional screw rod 16 to rotate, so that the moving blocks 17 respectively threadedly connected to the two ends of the first bidirectional screw rod 16 move toward or away from each other, thereby adjusting the distance between the two clamping parts to make them compatible with the flexible circuit board; when it is necessary to adjust the clamping thickness of the clamping mechanism 4, the threaded knob 24 is rotated, thereby driving the clamping plate 23 to move up and down along the vertical plate of the L-shaped plate 22, thereby adjusting the distance between the clamping plate 23 and the L-shaped plate 22, so that flexible circuit boards of different sizes can be stably clamped and fixed, effectively preventing the flexible circuit board from bending, deformation or displacement during the detection process, thereby improving the accuracy and precision of the detection.

[0042] The working principle of the adjustment component 7 is as follows: the adjustment motor 28 drives the second bidirectional screw rod 27 to rotate in the installation groove 26, thereby driving the lifting blocks 29 respectively threadedly connected to the two ends of the second bidirectional screw rod 27 to move away from or approach each other, thereby achieving the purpose of adjusting the distance between the detection component 6 and the front and back surfaces of the flexible circuit board in the slot 3, meeting the detection requirements of flexible circuit boards of different sizes, and ensuring the correct and accurate detection of the circuit board by the detection component 6.

[0043] Among them, the detection component 6 includes a fixed plate 30 arranged on the lifting block 29, a detection camera 31 installed on the fixed plate 30, a ring-shaped light source 32 arranged around the outside of the detection camera 31, and a fixed rod 33 connected between the fixed plate 30 and the ring-shaped light source 32; the ring-shaped light source 32 is arranged on the outside of the detection camera 31, which can make the lighting of the flexible circuit board more uniform, further ensure the consistency of the brightness of the captured image, reduce interference factors such as shadows and reflections, improve image quality and the accuracy of visual detection, and thus help to reduce missed detection and false detection rates.

[0044] Among them, in order to accurately track and manage the flexible circuit board placed in the slot 3, thereby improving the detection efficiency, the upper end surface of the conveyor plate is provided with multiple two-dimensional codes 34 corresponding to the slot 3 one by one, and the outer side wall of the adjustment seat 25 is provided with a mounting plate 35, and the mounting plate 35 is provided with a two-dimensional code scanner 36.
