TECHNICAL FIELD

[0001] The application belongs to the technical field of cutting the ribs of a chip tantalum capacitor strip, and particularly relates to an automatic rib cutting process for a chip tantalum capacitor strip. BACKGROUND

[0002] With the continuous development of electronic information equipment, the demand for chip tantalum capacitors is increasing. Under the premise of ensuring quality, improving production capacity has become one of the most urgent things in the current electronic component industry. In addition to increasing production capacity by purchasing equipment, the number of products loaded on each lead frame can also be increased to improve production capacity.

[0003] However, once the product density of each lead frame is increased, the plastic overflow between products will be short and firm, making it difficult to clean the overflow during the sandblasting process. The residual overflow will affect the pin forming of the product in the subsequent process, so the lead frame needs to be cut before pin forming. The current market requires manual operation, which reduces production efficiency and increases labor costs, and needs to be further improved. SUMMARY
