Description

Technical Field

[0001] This utility model relates to the field of ballpoint pen technology, specifically to an integrated measuring device for ballpoint pen tips. Background Technology

[0002] Currently, my country has become a major exporter of pen manufacturing products worldwide. Statistics show that in 2009, the total output of my country's pen industry reached 38 billion pens. Among various types of pens, ballpoint pens had the largest output, at 13.6 billion pens annually, 70% of which were exported to countries all over the world. As a crucial component of ballpoint pens, the pen tip requires high precision; otherwise, the pen will not write smoothly, necessitating testing of the pen tip.

[0003] In the prior art, CN212807889U discloses a pen tip ball bearing force measuring device. By placing the pen tip to be tested on a support pin, direct contact with the ball bearing can be achieved. A small hydraulic rod is used to slowly and uniformly lower the pen tip to apply pressure. A pressure sensor collects the pen tip ball bearing force information in real time and sends it to an industrial control computer. An industrial camera collects the pen tip deformation information in real time and sends it to the industrial control computer. The industrial control computer analyzes the pen tip deformation image in real time, determines whether the pen tip has deformed, and outputs the pen tip ball bearing force information corresponding to the deformation.

[0004] However, the above-mentioned device lacks a mechanism for positioning the pen tip during use. The pen tip may move during the test, leading to inaccurate measurements. Furthermore, it is inconvenient to replace the support pin. After multiple measurements, the support pin may wear out, affecting the measurement results. Therefore, it does not meet the existing requirements. To address this, we propose an integrated measuring device for ballpoint pen tips. Utility Model Content
