Be provided with the screw 37A that the threaded shank 54 for push rod 49 described later is screwed at the base end part (upper end of Fig. 1) of slide plate portion 37.Suitably rotate this push rod 49 by the threaded shank 54 that in this screw 37A, is screwed into push rod 49, thereby adjust the position of slide plate portion 37.The leading section of slide plate portion 37 (bottom of Fig. 1) expansion forms flange shape, and cradle portion 38 is installed.
Be provided with for the chimeric embeded slot 53 of limiter 50 at the pars intermedia of push rod 49.This embeded slot 53 forms ring-type at the pars intermedia of push rod 49.Embeded slot 53 be located at limiter 50 and under the state of positioning support push rod 49 with these embeded slot 53 tablings, by the short circuit member 33 of cradle portion 38 supportings of slide plate portion 37 reliably with the contacted positions of a plurality of terminal 5C (location of short circuit) of liquid crystal panel 5.Be provided with threaded shank 54 in the bottom of push rod 49, this threaded shank 54 is screwed in the slide plate portion 37.Thus, push rod 49 is supported in location of short circuit by limiter 50 and embeded slot 53 tablings, when the terminal 5C of liquid crystal panel 5 contacts with probe 25, by slide plate portion 37 grades short circuit member 33 is pressed on the terminal 5C.
The probe unit 11 that below constitutes like that has effect as described below.In addition, because the effect of testing fixture integral body is identical with in the past testing fixture, therefore, describe at this center that act as with probe unit 11.
By making liquid crystal panel 5 contraposition exactly that is supported on the work stage 10, and the terminal 5C of liquid crystal panel 5 and the probe 25 of probe member 24 are in contact with one another.
Then, will carry out the inspection of lighting of liquid crystal panel 5 by cable 30 grades from the terminal 5C that probe 25 imposes on liquid crystal panel 5 by the inspection signal that signal generator 31 produces.
At this moment, when unfavorable condition took place, the corresponding short-circuiting means 15 in position with producing this unfavorable condition of probe unit 11 switched to the short-circuit mode that carries out test for short-circuit from standby mode.
Be generally standby mode.That is, the chimeric claw 50A of limiter 50 breaks away from from the embeded slot 53 of push rod 49, and slide plate portion 37 is by spring 52 pull-up and become standby mode in the position of readiness standby upward.Thus, short circuit member 33 is supported in the position of leaving from terminal 5C.Switch to short-circuit mode from this standby mode.
Under short-circuit mode, press lower push-rod 49, make the embeded slot 53 of push rod 49 and limiter 50 chimeric claw 50A aligned in position and be screwed into limiter 50, make chimeric claw 50A and embeded slot 53 tablings.Thus, the top ends of short circuit member 33 (bottom) is supported in and the position of the top equal height of probe 25 or the position lower than the top of probe 25.
Under this state, make work stage 10 action, when the terminal 5C of liquid crystal panel 5 was contacted with probe 25, all terminal 5C that short circuit member 33 is contacted with probe 25 contacted, and make these terminals 5C short circuit all.
Under this state, when producing the inspection signal by signal generator 31, even in unfavorable condition is under the situation about being caused by probe unit, be sent to all the terminal 5C under the state that inspection signal on each probe 25 also can impose on by 33 short circuits of short circuit member.That is, will check that signal imposes on each terminal 5C reliably.
Under this short-circuit mode, when on liquid crystal panel 5, producing unfavorable condition, be the unfavorable condition that causes by panel as can be known.On the other hand, under short-circuit mode, not producing unfavorable condition following time on liquid crystal panel 5, is the unfavorable condition that is caused by probe unit as can be known.Carry out later processing based on this.
In probe unit 11, loosen limiter 50 and chimeric claw 50A is broken away from from embeded slot 53, make slide plate portion 37 be returned to position of readiness.
When maintenance, as shown in Figure 4, pull down screw 43, making short-circuiting means 15 is that rotate at the center with the hinge 41 as rotating mechanism.Under this state, carry out the maintenance of probe member 24 grades.Also carry out the maintenance of short-circuiting means 15 self.
As mentioned above, short-circuiting means 15 is set on probe unit 13, can switches standby mode and short-circuit mode, therefore, check when producing unfavorable condition in the operation lighting, can be easily and judge reliably this unfavorable condition be cause by panel or cause by probe unit.
Thus, do not need setting in addition and light the different inspection operation of inspection operation, can seek to check efficiency of operationization.
In addition, because short-circuiting means 15 is that rotate at the center with the hinge 41 as rotating mechanism, therefore can easily keep in repair.
Because short circuit member 33 is by the integral body of a plurality of terminal 5C of covering liquid crystal panel 5, and constitutes with the contacted conducting rubber of a plurality of terminal 5C of liquid crystal panel 5 simultaneously, therefore, can be easily and make all terminal 5C short circuits reliably.
Pressing mechanism 34 comprises slide plate portion 37 and mobile support 39, it is moving that sliding in state of short circuit member 33 relatively supported at the terminal 5C that makes short circuit member 33 with liquid crystal panel 5 by this slide plate portion 37, and short circuit member 33 can be loaded and unloaded with respect to terminal 5C, this mobile support 39 makes this slide plate portion 37 support this slide plate portion 37 movably between position of readiness and location of short circuit, therefore, when producing unfavorable condition, can seek to check efficiency of operationization by manually easily switching to short-circuit mode.
The 1st variation
