Description

Technical Field

[0001] The utility model belongs to the technical field of lead frames, and in particular relates to a handheld curved knife measuring instrument for a high-power lead frame metal processing. Background Art

[0002] The metal processing refers to the process of using metal materials to process and manufacture products such as lead frames. In the metal processing, the control of the lead frame's bend knife is a key parameter that affects the quality and performance of the product. The bend knife refers to the degree of bending of the material during the processing. For metal materials, a suitable bend knife can ensure the processing accuracy and overall quality of the product. At present, the metal processing process's control of the material's bend knife mainly depends on the measurement of the head and tail of each roll of material.

[0003] The traditional practice is to cut the material and then send it to the quality inspection department for scimitar measurement. However, this method will seriously affect production efficiency because it is necessary to stop the machine to wait for the measurement results. It will also increase production costs and cause material waste. However, for the middle part of each roll of material, accurate scimitar measurement cannot be performed without cutting it. This situation leads to the inability to fully monitor the scimitar during the production process, which will cause unstable or unqualified product quality. In order to solve this problem, it is necessary to provide a new type of high-power lead frame gold processing handheld scimitar measuring instrument. This instrument is designed to be light and easy to carry and operate. During the production process, the operator can hold the instrument at any time to measure the scimitar of the material, realize real-time monitoring and adjustment, avoid equipment shutdown and material waste, and improve production efficiency and quality. Through this innovative measurement method, the problem of scimitar control in the gold processing process can be effectively solved, thereby improving product processing accuracy and overall quality.
