To describe the preferred embodiments of the present invention below in detail, the example is shown in the drawings.In institute's drawings attached, with identical Reference numeral, refer to same or analogous parts as far as possible.It should be noted in the discussion above that the embodiments described herein, only for illustrating, is not limited to the present invention.
Fig. 3 is the side view of head motion failure detection device of the present invention.As shown in the figure, described head motion failure detection device comprises: kinematic link 13 and connecting shaft disk 12, wherein one end of kinematic link 13 is fixed on motor 10(as shown in Figure 1) connecting shaft disk 12 on, move reciprocatingly together with described connecting shaft disk 12; Described head motion failure detection device also comprises: sensor 14, be arranged on the sidepiece of the moving area of kinematic link 13, for carrying out sensing kinematic link 13 according to the movement of kinematic link 13, whether rupture, preferably, sensor 14 is arranged on the sidepiece of kinematic link 13, and whether the action that is beneficial to sensing kinematic link 13 is normal.
Fig. 4 is the structured flowchart of the sensor of head motion failure detection device of the present invention.As shown in the figure, sensor 14 comprises: timing unit 141, the time interval moving reciprocatingly for default kinematic link 13; Whether sensing cell 142, interdict sensor 14 for sensing kinematic link 13 within the time interval setting; And alarm unit 143, for the time interval sensing and default warning time are compared, and give the alarm according to comparative result.
Particularly, first, timing unit 141 can be preset the time interval (for example 5 seconds) that kinematic link 13 moves reciprocatingly, and that is to say, kinematic link 13 can interdict sensor 14 once every 5 seconds.Secondly, in the time interval between the every twice blocking sensor 14 of sensing cell 142 sensing kinematic links 13, if now this time interval is 5 seconds, represent kinematic link 13 normal operations; Otherwise, represent kinematic link 13 operation exceptions.Then the real time interval (for example 30 seconds) that, sensing cell 142 moves reciprocatingly the kinematic link sensing 13 sends to alarm unit 143.Finally, alarm unit 143 compares the sensing result receiving from sensing cell 142 (for example time interval of 30 seconds) and default warning time (for example 20 seconds), for example, for example, if the time interval sensing (30 seconds) exceedes warning time (20 seconds), gives the alarm.
It should be noted that, the signal of sensor 14 can send back board by PLC program, here, PLC(Programmable Logic Controller, programmable logic controller (PLC)) be the electronic installation of the digital operation operation of a kind of special application under industrial environment and design.It adopts the storer that can program, be used for storing the user oriented instructions such as actuating logic computing, sequential operation, timing, counting and arithmetical operation operation therein, and can, by digital or analog input and output, control various types of machinery or production run.The communication link of PLC can be divided into wired and wireless two kinds, and wired data link has RS-485 etc., and wireless data link has MDS data radio station etc.
In addition, sensor 14 itself comprises that signal transmitting and signal receive two parts, and the interface of board end is mainly controlled relevant I/O contact by PLC program.Due to the design difference of each equipment, therefore time interval difference to some extent, therefore, the present invention can utilize PLC to revise the default time interval, to reach best time control mode.
The present invention is applicable to be furnished with back and forth or the board of the mechanism of rocking action, its applicable equipment can be for example medicine liquid spray pipeline, its glass guide channel of the photoresistance stripping machine Be liquid spraying pipeline in its etching dipper of Wet-type etching machine, or other has the identical reciprocal or equipment of the mechanism of rocking action.
Below, with reference to Fig. 5, take the medicine liquid spray pipeline in its etching dipper of Wet-type etching machine as example, by an example, the detection method of head motion failure detection device is described in detail.

Particularly, first, when motor 10 normal operation, the shake power that is delivered to connecting shaft disk 12 by the motor shaft 11 being connected with motor 10 moves reciprocatingly kinematic link 13 in the sense of rotation of motor 10.Then, kinematic link 13 can interdict sensor 14 within the default time interval of the timing unit 141 of sensor 14 (being assumed to be 5 seconds), if the time interval between the every twice blocking sensor 14 of the sensing cell of sensor 14 142 sensing kinematic links 13 is 5 seconds, represent kinematic link 13 normal operations; Otherwise, (that is, kinematic link 13 probably ruptures in the process moving reciprocatingly, and kinematic link 13 cannot be moved reciprocatingly with connecting shaft disk 12 to represent kinematic link 13 operation exceptions, that is to say, kinematic link 13 cannot interdict sensor 14 within the default time interval.）。Then the real time interval (for example 30 seconds) that, sensing cell 142 moves reciprocatingly the kinematic link sensing 13 sends to alarm unit 143.Finally, alarm unit 143 compares the sensing result receiving from sensing cell 142 (for example time interval of 30 seconds) and default warning time (for example 20 seconds), for example, for example, if the time interval sensing (30 seconds) exceedes warning time (20 seconds), gives the alarm.
In sum, head motion failure detection device of the present invention has increased sensor 14 in head motion, make can to detect in time compared to existing head motion that the kinematic link of head motion in board exists abnormal also gives the alarm, thereby reduce the fraction defective of manufacturing cost and product, and further improve formation efficiency.
Fig. 6 is the process flow diagram of head motion abatement detecting method of the present invention.As shown in the figure, described abatement detecting method comprises the following steps: one end of kinematic link is fixed on the connecting shaft disk of motor, described kinematic link is moved reciprocatingly together with described connecting shaft disk; And by sensor setting the sidepiece at the moving area of described kinematic link, make described sensor carry out kinematic link described in sensing according to the movement of described kinematic link and whether rupture.
In one embodiment, sensor according to the movement of kinematic link come sensing kinematic link whether occur fracture specifically comprise: the time interval that default kinematic link moves reciprocatingly; Whether sensing kinematic link interdicts sensor within the time interval setting; And the time interval sensing and default warning time are compared, and give the alarm according to comparative result.
Owing to head motion abatement detecting method being have been described in detail as an example of medicine liquid spray pipeline example hereinbefore, therefore do not repeat them here.
In sum, head motion failure detection device of the present invention and method, can detect in time that the kinematic link of head motion in board exists abnormal also gives the alarm, so that maintenance personal gets involved and processes dependent failure in time, thereby reduce the fraction defective of manufacturing cost and product, and further improve formation efficiency.
