Description

Technical Field

[0001] The present invention relates to the field of FFC processing equipment, and particularly relates to an FFC two-way detection and cutting device. Background Art

[0002] When FFC is produced in the form of a coil, it is usually distributed at intervals on different planes. Therefore, when the product needs to be cut out from the coil, it is necessary to align the position of the gold fingers on the FFC for cutting. In the past, manual cutting was usually used, which not only had low work efficiency but also low precision. Although some automated devices have emerged for cutting now, the technology is not yet perfect, with low stability and low cutting precision. In addition, the previous detection and cutting were carried out separately. After the FFC tape is produced, it is necessary to detect items such as the pitch, total pitch, total width, edge width, bare barrel length, presence or absence of a reinforcing plate, and reinforcing plate scribing of the FFC through a detection device. After the detection is completed, it is then cut manually or by a device. Since there will be errors during cutting, generally, the cut products need to be detected again. Therefore, it is necessary to detect the cut products again manually or by a device, which has a complex process and requires multiple devices or manual labor to complete, making it extremely inconvenient to use.

[0032] The working principle of this embodiment:

[0033] The feeding device 1 drives the unwinding shaft 12 to rotate through the unwinding shaft driving device 13 to unwind the coil material and supply it to the left feeding device 2. The left feeding device 2 pulls the tape to convey it to the right, and transports the position of the gold fingers on the FFC tape to the position of the clamping assembly 41 correspondingly. The clamping assembly 41 clamps the tape. At this time, the right end of the FFC tape enters the right feeding device 5. The right feeding device 5 clamps the right end of the FFC tape. When the product on the FFC tape faces upward, the upper CCD detection and positioning assembly 42 takes pictures and positions and detects the FFC at this position, and transmits the position signal to the left feeding device 2 and the right feeding device 5 to control the driving stroke thereof. After the detection is completed, the clamping assembly 41 releases the tape, and the left feeding device 2 and the right feeding device 5 move synchronously to drive the FFC tape to convey to the left and transport the FFC to be cut to the two-way cutting device 3. After the two-way cutting device 3 drives the upper cutting knife 342 to move downward through the Z-axis driving device 32 to cut the tape, the right tape pulling device drives the cut tape to convey to the right, and transports the position of the gold fingers to the detection device 4 for re-detection to determine whether the product is good or not. The good products are directly sent out and received through one of the receiving slots 621 of the receiving box 62. The defective products are cut by the defective product cutting assembly 7 and then sent out. For the products facing downward on the FFC tape, the lower CCD detection and positioning assembly 43 takes pictures and positions and detects the FFC, transports the detected FFC to the two-way cutting device 3, and controls the lower cutting knife 352 to move upward to cut out the product. After the product facing downward is cut out, it is also detected by the detection device 4 again. The good products are directly sent out from the right side and received by the other receiving slot 621 of the receiving box 62. The defective products are cut and then sent out.

[0034] The above does not impose any limitation on the technical scope of the present invention.
