Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a full-automatic assembly, testing and packaging machine for fuses. Background Art

[0002] The double-cap fuse includes the fuse body and the pin copper caps at both ends of the fuse body. The production process mainly includes assembling the pressure caps (pressing the pin copper caps into both ends of the fuse), straightening the pins, testing whether the resistance value meets the requirements, checking whether the appearance and size meet the standards, and packaging the assembled fuse products. These processes are performed manually. Manual assembly, taping / bagging / bulk packaging are time-consuming and labor-intensive, with low production efficiency and poor product quality control. Since the product is small and has various appearance problems, it is not easy to detect small defects and all defects through manual inspection of the appearance, leading to customer complaints.

[0003] A Chinese patent with patent number CN202122946206.1 discloses a fuse cap shaping, testing and taping machine. The rolling component and the shaping base plate have narrow actual shaping surfaces, and secondary rolling is used, which is costly. In addition, the shaping mechanism uses a second drive component, which requires an additional power element. Due to the use of hard gear connection, it is not possible to directly use a large rubber wheel for shaping, and the pin bending deformation is relatively large, causing jamming.

[0004] Both the first detection mechanism and the second detection mechanism use CCD visual detectors. Although the second detection mechanism uses four groups, each group actually detects and identifies one-fourth of the arc surface of the fuse. When traditional cameras detect the appearance of cylindrical products, the area facing the camera is relatively clear, while the surrounding area is far away from the camera and is on the arc surface, making it difficult to detect accurately and the detection quality is not high.

[0005] A fuse cap shaping test taping all-in-one machine. Fuses can only be packaged in the form of taping. However, in actual use, customers have different requirements for product packaging. Some require bag packaging, and a certain amount of fuses are installed in the packaging bag. A fuse cap shaping test taping all-in-one machine cannot meet the above packaging requirements.

[0006] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a fully automatic assembly, testing and packaging machine for fuses. Summary of the invention
