The invention also discloses a kind of online wheel hub reading code method, comprise the following steps,
S1: motor 2 is controlled swing bolster 3 and rotated, swing bolster 3 drives code reader 4 to reading code object place;
S2: code reader 4 carries out reading code;
S3: code reader 4 adopts minimum rotation angle control strategy to reset under the control of code reader resetting means;
S4: repeat S1 to S3 step.
Particularly, please continue to refer to Fig. 6, state when swing bolster 3 is positioned at initial position is set to the first zero, state when swing bolster 3 is positioned at 360 degree position was set to for the second zero point, two state lower rotating disc at zero point orientation of 6 are identical with the signal condition of its three position transducers 5 in top, it is distinguished according to limited block 9 and the contact point of swing bolster 3 and determines, shown in limited block 9 solid lines, position is the first zero, and dotted line position was the second zero point.Herein, for the ease of distinguishing, when swing bolster 3 is positioned to initial position, the position transducer nearest apart from limited block 9 is defined as primary importance sensor 51, be defined as second place sensor 52 apart from limited block 9 second near position transducers, be defined as the 3rd position transducer 53 apart from limited block 9 position transducer farthest.The reset direction of swing bolster 3 adopts minimum rotation angle control strategy, when the starting point of swing bolster 3 is the first zero, swing bolster 3 drives code reader 4 to scan along clockwise direction, in the time that code reader 4 detects pattern in 2 D code, if primary importance sensor 51, the equal no signal of the 3rd position transducer 53, show that motor 2 rotation angle positions 0 spend, without reset; If the 3rd position transducer 53 has signal, primary importance sensor 51 no signals, show that motor 2 rotation angle are within the scope of 0 ~ 180 degree, reset direction is counterclockwise; If primary importance sensor 51, the 3rd position transducer 53 all have signal, show that motor rotation angle is just in time 180 degree, reset direction gage is decided to be counterclockwise; If the 3rd position transducer 53 no signals, primary importance sensor 51 have signal, show that motor 2 rotation angle are within the scope of 180 ~ 360 degree, reset direction is clockwise.In the time that swing bolster 3 reset to for the second zero point, code reader 4 is along scanning counterclockwise, and its reset rule is with above-mentioned.Herein, the signal that act as of position transducer 5 is proofreaded, and as discovery signals contradiction, controller will give the alarm.
Disclosed online wheel hub code-reading apparatus, in reading code process, code reader 4 can automatic rotation and the Quick Response Code of searching hub surface carry out reading code operation, traditional manual operation process has been save in whole reading code operating process, has greatly improved work efficiency; And, disclosed online wheel hub code-reading apparatus, its code reader 4 can reset with prestissimo completing after reading code operation, to carry out reading code operation next time, is applicable to the wheel hub production line that production efficiency is higher.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
