    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Before describing in greater detail, it should note that the like elements are denoted by similar reference numerals throughout the disclosure.
  • Referring to Fig 2 , an apparatus 3 for fastener inspection and sorting of the first preferred embodiment comprises an inlet feeding system 31 for orientating and aligning objects 4, a turntable 32 connecting to an exit of the inlet feeding system 31 and having a plurality of grooves 321 formed in an outer periphery thereof, an inspecting machine 33 for performing signals of the objects 4, a determining device 34 electrically communicating with the inspecting machine 33 to analyze quality of the objects 4, and an outlet conveyer system 35 disposed at one side of the turntable 32 for sorting the objects 4 into defective and non-defective according to analyzed results of the determining device 34; wherein, the objects 4 can be screws or nuts and hereinafter screws are adopted. Additionally, the inspecting machine 33 is utilized by an eddy current inspecting probe in the following embodiments of the present invention.
  • Further referring to Fig. 3 , an auxiliary device 5 is disposed beside the turntable 32 and provides with a support base 51 located beside the turntable 32 and extended upon the grooves 321, and a driving assembly 52 which has a power source 521 pivoted to the support base 51 and a steering rod 522 having one end thereof connected to the inspecting machine 33 and its other end pivoted to the support base 51, thereby allowing the power source 521 to straight rotate the steering rod 522 as well as the inspecting machine 33.
  • Referring to Fig. 2 and 3 , while operating, each object 4 is sequentially introduced into the groove 321 of the turntable 32 along the inlet feeding system 31 and further transferred to the appropriate detecting station, namely positioned under the support base 51 of the auxiliary device 5. Thereupon the power source 521 operatively drives the steering rod 522 rotating, and the inspecting machine 33 becomes revolving round the object 4 so as to capture circumferential defect signals thereof from different orientations. Subsequently, the captured signals are transmitted to the determining device 34 and analyzed thereby; further in view of the measuring result, the outlet conveyer system 35 would properly sort and discard the defective or malformed screw 4, thereby efficiently increasing the inspecting quality and reducing the inaccurate determination.
  • Referring to Fig. 4 and 5 , the second preferred embodiment of the present invention still has similar elements to the first embodiment; however their auxiliary devices 5 have respective formations by different installations. Particularly, a holding assembly 6 is pivoted to the auxiliary device 5 and provides with a holding base 61 attached to the power source 521 and driven thereby, and a propulsion device 7 for indirectly driving the power source 521; wherein, the holding base 61 includes a magnetic member 62 mounted therein and contains a drive plug 64 disposed at its free end for being formed complementary to a drive socket 41 of the object 4. The magnetic member 62 can be used by suitable materials, e. g. a permanent magnet or an electromagnet, and the permanent magnet is adopted to attract the object 4 in the present invention.
  • Still further, the propulsion device 7 has a casing base 71 fastened to the support base 51 for disposing the power source 521 therein and a controlling device 72 pivotally mounted on the base 51. The casing base 71 further has a slot 711 arranged thereon and the power source 521 has a protrusion 5211 laterally disposed thereon for protruding out of the slot 711 and communicating with the controlling device 72. Additionally, the steering rod 522 can still has one end thereof connected to the inspecting machine 33 and other end to be fastened to the support base 51 (shown in Fig. 6 ), or the rod 522 changes its other end to be secured to the casing base 71 (shown in Fig. 4 and 5 ). The above two installations result in immobilizing the steering rod 522 and the inspecting machine 33. Moreover, the controlling device 72 includes a drive mean 721 disposed on the support base 51 and a motor drive unit 722 (e.g. a pneumatic cylinder) engaged to one end of the drive mean 721; wherein, the drive mean has a fork-like opening 7211 arranged on the other end thereof for clamping the protrusion 5211, thereby motivating the power source 521 to perform in upward and downward movements.
  • Referring to Fig. 5 , in operation, the motor drive unit 722 begins to push the drive mean 721 forward while the object 4 is positioned under the holding base 61, whereby the protrusion 5211 is initially driven by the drive mean 721 to be moved downward along the slot 711 for descending the power source 521 and the holding base 61 as well. Further the magnetic member 62 substantially contacts the head of the object 4 and attracts it to be deviated from the turntable 32 when pulling the drive mean 721; subsequently, the power source 521 begins to drive the holding base 61 rotating and the object 4 also becomes spinning in the detection range of the immobilized inspecting machine 33, so that the inspecting machine 33 is able to perform defect detections of the object 4 from different orientations and passes the integral signals for the following inspections and dispensing, hence reducing the possibility of inaccurate determination and increasing the quality of the inspection and sorting. Finally, the turntable 32 merely pushes to relieve the object 4 of the attraction and restarts detecting the following object 4.
  • Referring to Fig. 7 , the fourth preferred embodiment of the present invention mainly comprises the concatenation of elements as the same as the second preferred embodiment. Differentially, the holding base 61 is wrapped by a shield 63. In this manner, the shield 63 assists to absorb the shock and the drive plug 64 inserted into the socket 41 prevents the object 4 from being swung when the magnetic member 62 attracts it out of the turntable 32. The subsequent procedures are the same as the previous embodiment and herein are omitted.
  • To sum up, the present invention takes advantages of the auxiliary device assisting in capturing the circumferential detection of each object from different orientations by directly driving the inspecting machine rotating or spinning the object under the magnetic attracting while immobilizing the inspecting machine, thereby obtaining accurate analyses with high efficiency and increasing the inspecting quality.
  • While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
