Description

Technical Field

[0001] This utility model relates to the field of transistor processing, and in particular to a marking device for a component lead forming machine. Background Technology

[0002] After transistors are manufactured, they need to be bolted to a heatsink. To ensure that the through-holes of the heatsink and the through-holes of the transistor are aligned, auxiliary lines are drawn on the outer surfaces of both the transistor and the heatsink. These lines help to align the transistor and the heatsink during the manufacturing process, making the alignment of the transistor and the heatsink more precise and facilitating subsequent bolting.

[0003] However, during the production process, transistors and heat sinks are typically placed in a feed channel and then transported to a component lead forming machine for processing. On-site personnel use scribing tools to draw lines on the transistors and heat sinks. The entire scribing process is done manually, and fatigue can easily lead to operational errors under prolonged work.

[0004] Therefore, this utility model provides a marking device for a component lead forming machine to solve the problem of drawing errors caused by fatigue after long-term operation. Utility Model Content
