Screw detection device for screw manufacturing equipment

Abstract

A screw detection device for use in a screw manufacturing equipment comprises: a conduction-sensing sensor (100) in contact with a tail portion of a metal wire (W) for manufacturing a screw which is drawn into the interior of the screw manufacturing equipment (S); a first setting portion (410) for setting a time period in which a current conducts when the conduction-sensing sensor (100) is in contact with the metal wire (W); a first determination portion (440) for determining whether the conduction-sensing sensor (100) is in contact with the metal wire (W) and determining that the wire (W) is normal or defective by performing a comparison with the time period set by the first setting portion (410); a display portion (490) for displaying, according to the determination made by the first determination portion (440), the determination indicating whether or not the wire (W) passes. When a product defect occurs in a screw manufacturing process, the screw detection device for use in the screw manufacturing equipment can perform real-time detection on the defective product and automatically separate and discard the same without interrupting the screw manufacturing equipment (S), and can perform filtering to quickly obtain and output screws with acceptable quality. Moreover, the invention has improved detection accuracy, reliability and increased productivity.

Description

technical field [0001] The present invention is a screw detection device for screw manufacturing equipment, which is characterized in that the screw detection device can sense and distinguish the defects of screws in real time during the continuous screw production operation using screw manufacturing equipment, and detect defective products and qualified products. Screening and shipping. Background technique [0002] Generally, a screw, as a mechanical element, is often used to fasten building materials and machine parts, etc. It has a head with a cross-shaped or inline groove formed on it, and a body with threads formed on the outer diameter surface. [0003] The manufacture of the above-mentioned screws usually uses automated manufacturing equipment for continuous production operations, and the screws produced by the machine equipment often have defects due to the precision of the manufacturing equipment, the quality of the raw material wire, the working environment condit...

AI Technical Summary

Problems solved by technology

[0010] In the prior art, there is no additional device configured to detect and screen a large number of screws produced by the screw manufacturing equipment in a short period of time. Instead, it is necessary to manually sample the screws delivered by the screw manufacturing equipment. When defective products are found, then Will interrupt manufacturing equipment to find out the cause of defective products

[0011] However, most of the above-mentioned existing technical means need to be equipped with operators separately for the detection and screening work, which has caused unnecessary waste of personnel and inevitably increased production costs, and this detection method through the visual inspection of operators , will greatly reduce the efficiency and reliability of detection

[0012] In addition, because the production equipment needs to be interrupted when the product is defective, it will inevitably lead to the extension of the production time, resulting in a decrease in production efficiency
