Description

Technical Field

[0001] This utility model relates to the field of copper bar screw fastening technology, and in particular to a copper bar screw fastening device. Background Technology

[0002] In the manufacturing process of copper bars, screw fastening is one of the key steps, and its quality directly affects the assembly performance and reliability of the copper bars. The existing copper bar screw fastening process has the following problems:

[0003] Insufficient positioning accuracy of copper bar: Traditional positioning structures often use manual clamping or simple limiting, which can easily lead to screw attachment position displacement due to positioning deviation, resulting in defects such as stripping and misalignment, affecting product quality.

[0004] Delayed screw fastening quality inspection: Whether the height of the screws after fastening meets the standard and whether there is any damage to the appearance (such as screw head deformation, scratches, etc.) largely depends on manual visual inspection, which is not only inefficient, but also prone to inspection errors due to human fatigue, resulting in the omission of defective products.

[0005] Low level of automation: The loading and unloading of copper bars and the recycling of defective products rely heavily on manual operation, which not only increases labor costs, but also makes it difficult to adapt to the automated process of the production line, thus restricting production efficiency.

[0006] Defective product recycling is inconvenient: Defective products detected need to be manually transported to the recycling area, which can easily cause secondary damage due to improper operation and affect the continuity of production.

[0007] Therefore, in view of the problems of inaccurate positioning of copper bar, low efficiency of fastening quality inspection, insufficient automation and inconvenience of defective product recycling in the existing technology, there is an urgent need to design a copper bar screw fastening device that integrates precise positioning, automatic detection, automatic loading and unloading and automatic recycling of defective products.
