Description
Technical Field
The invention belongs to the field of fasteners, and particularly relates to a fastener with a traceability sensor and a preparation method of the fastener.
Background
At present, the technology of measuring the pretightening force of the external thread fastener by using an ultrasonic signal excited by a sensor by preparing the sensor on the external thread fastener has better application prospect.
In prior methods, sensors have been incorporated into the surface of a threaded fastener in two ways. One is to fix the sheet-shaped sensor to the surface of the threaded fastener integrally by means of pasting or welding, and the other is to deposit the layered structures of the growth sensor by means of vacuum coating. Either way, this is achieved by occupying a large amount of surface area of the head end face of the fastener.
For the fastener, in order to realize the traceability of the fastener processing and manufacturing, the end face of the head of the fastener is marked, and the marking contents mainly comprise: the model, specification, manufacturer mark and the like of the product. With the increasingly strict requirement of customers on the traceability of the fastener, some customers simultaneously require the head end face of the fastener to record the information of the product such as the factory batch number, the serial number and the like, so that the combination of the sensor and the fastener is difficult due to the large marking content, and the application range and the prospect of the sensor fastener are limited to a certain extent.
In addition, most fasteners are assembled, the head end face is often designed into a cross groove, a gear groove, an inner hexagon and the like, the surface area of the head end face is further reduced, and the sensor cannot be effectively combined with the head end face of the fastener. For the scheme of processing the tail part of the sensor, the tail part of the conventional bolt is usually in a hidden state due to the fact that the effective diameter of the tail part of the conventional bolt is very small and the fastener is in the actual use process, and difficulty is brought to actual detection.
Meanwhile, in order to realize the function of the sensor, the protective film layer in the three-layer structure (piezoelectric film layer, protective film layer, and polarization layer) of the conventional sensor needs to separate the polarization layer into two completely insulated parts. In order to manufacture the structure, the piezoelectric film layer and the protective film layer are generally processed, then the shielding material is adhered to the surface of the protective film layer, after the electric polarization layer is deposited, the adhered shielding material is removed, the part is not subjected to the electric polarization layer deposition, so that the protective film layer separates the electric polarization layer into two completely insulated parts, and a loop is formed in the detection process, as shown in fig. 1.
