Miniature workpiece sorting equipment

Abstract

The invention discloses miniature workpiece sorting equipment, and belongs to the technical field of miniature workpiece detection. The miniature workpiece sorting equipment comprises a material taking rod capable of doing vertical reciprocating movement, and a gravity sorting device capable of being used for pulling a workpiece to be tested, wherein the material taking rod passes through the gravity sorting device; an upper winnowing pipe capable of blowing away the workpiece to be tested is also arranged at one side of the gravity sorting device; a lower winnowing pipe capable of blowing away the workpiece to be tested is arranged under the gravity sorting device. The pulling intensity on the tubular workpiece to be tested is regulated and controlled through the gravity sorting device, the material taking rod can lift up a qualified product in an ascending process; the gravity sorting device can enable the qualified tubular workpiece to ascend and pass; then, the upper winnowing pipeblows away the workpiece to be tested, so that the sorting is convenient; a proper gravity standard block only needs to be set; drawing force does not need to be tested by a test tool; the monitoringis convenient and fast; the drawing force intensity is more standard; the measurement is not needed in each time of detection.

Description

technical field [0001] The invention relates to the technical field of micro workpiece detection, in particular to a sorting device for micro workpieces. Background technique [0002] Micro workpiece is a kind of precision component, which is used in electronic products and hardware parts of some precision instruments. Now electronic products often use cylindrical micro workpieces with through holes. Such cylindrical workpieces are often made of copper, and some electronic products are often made of copper. The use environment is relatively harsh, and strong vibration or pulling use often occurs. At this time, the general cylindrical workpiece processed cannot be excluded from this use condition. Some equipments are used for drawing the inner wall of the cylindrical workpiece. The strength is required to be controlled within the accurate tension range, which not only has high requirements on the inner diameter, but also has high requirements on the tensile force. If it fails...

[0002] Micro workpiece is a kind of precision component, which is used in electronic products and hardware parts of some precision instruments. Now electronic products often use cylindrical micro workpieces with through holes. Such cylindrical workpieces are often made of copper, and some electronic products The working environment is relatively harsh, and strong vibration or pulling often occurs. At this time, the general cylindrical workpiece processed cannot be unsuitable for this kind of working condition. Some equipment can pull the inner wall of the cylindrical workpiece. The strength is required to be controlled within the accurate tension range, which not only has high requirements for the inner diameter, but also has high requirements for the tensile strength. The equipment is prone to failure, and it is difficult to find the fault point and eliminate it, so the equipment using this cylindrical workpiece has high requirements for this cylindrical workpiece, but because of the mold production, the inner diameter of the cylindrical workpiece is different It is not big and cannot be distinguished by the naked eye, but it is difficult to control the accuracy of manual measurement, and it is even more difficult to measure when it exceeds the range of human strength. Moreover, it is time-consuming and labor-intensive, which makes it difficult to detect whether the drawing strength of such cylindrical workpieces meets the required requirements. In order to better detect whether the drawing strength of such cylindrical workpieces is qualified, a convenient detection method for cylindrical workpieces is now needed. The device of workpiece pulling force and inner diameter size can remove unqualified products without damaging the cylindrical workpiece, so as to ensure the qualified rate of cylindrical workpiece
