When the present embodiment uses, as shown in Figure 1, Figure 3, in the cavity volume 111 of casing 110, be provided with circuit arrangement and industrial computer (not shown) for detection of liquid crystal display 130.Liquid crystal display 130 is placed on the assigned address on the upper surface 121 of back up pad 120.Utilize wire that the circuit that is positioned at cavity volume 111 is connected with liquid crystal display 130.Wire two ends are respectively arranged with connector, on the circuit in cavity 111 and liquid crystal display, are provided with joining connector.Wire is through after through hole 124, the pegging graft to joining connector of the circuit arrangement in one end and cavity 111, the other end and liquid crystal display 130 upper to joining connector grafting.Connector with to join connector peg graft.Liquid crystal display 130 both sides cover a part for groove 125.Convenient liquid crystal display 130 and the taking-up liquid crystal display 130 placed.Groove 125 is set, both can have picked and placeed easily liquid crystal display 130, also can prevent from placing liquid crystal display 130 time, clash into liquid crystal display 130.If groove 125 is not set,, in the time placing liquid crystal display 130, before liquid crystal display 130 contacts upper surface 121, operating personnel must loose one's grip, and liquid crystal display 130 drops on upper surface 121.If prevent that liquid crystal display 130 from dropping on upper surface 121 and producing and clash into, must be very careful, and place according to certain mode just passable, length consuming time, efficiency is low.Arrange after groove 125, operating personnel's finger is arrested liquid crystal display 130, and in the time being placed on upper surface 121, finger can fall in groove 125, until liquid crystal display 130 contacts upper surface 121.Because liquid crystal display 130 is to be placed under operating personnel are hand-held on upper surface 121, and liquid crystal display 130 can entirety fall together, without complicated laying method is set again, both can place safely liquid crystal display 130, place when liquid crystal display 130 is placed and occur clashing into and damage liquid crystal display 130, and pick and place all very conveniently, consuming time short, efficiency is high.Utilize two limited blocks 123 to limit the placement location of liquid crystal display 130, in the time placing, can be placed on easily the position of appointment, conveniently coordinate with time writer 140.Two limited blocks 123 are arranged on the diagonal line of assigned address, only need two limited blocks 123 can limit exactly the position of liquid crystal display 130.
As shown in Figure 4, after liquid crystal display 130 is placed on upper surface 121.Asynchronous machine 170 starts, and drives slide block 152 and base 160 to move along guide rail 151 by driving-belt 173, and then drives time writer 140 to move along track groove 126.In time writer 140 moving process, transmitting terminal 141 is positioned at track groove 126 and all the time to liquid crystal display 130 electromagnetic signals.Liquid crystal display 130, receiving after the electromagnetic wave signal of time writer 140, can respond.Such as, on the route moving at time writer, set the position of multiple appointments, when electromagnetic wave signal is incident upon this position, this position is lit, and records this information, and this position performance is normal.These selected test positions can be also certain shape according to electromagnetic signal setting, as circle or toroidal.Be positioned at circle or an annulus on route and be all lit, can judge that these liquid crystal display 130 performances are normal.The length of track groove 126 is the stroke of time writer 140.Asynchronous machine 170 turns clockwise and is rotated counterclockwise, and can drive time writer 140 to-and-fro movements.Can judge that in one-time detection in the whether normal situation of liquid crystal display 130 performances, time writer 140 moves liquid crystal display 130 of rear detection, can detect another piece liquid crystal display 130 when return.Round trip, can detect two liquid crystal displays 130, and consuming time short, efficiency is high.Driving wheel 172 is arranged on two middle parts between support wheel 174, can make driving-belt 173 running stable, moves all the time according to fixed route, can prevent from rocking and affects the mobile alignment of time writer 140, weakens and detects effect.Utilize position detecting device 180, in the time that time writer 140 arrives stroke end, send electric signal, quit work or start reverse rotation by industrial computer control asynchronous machine 170, prevent that time writer 140 is moved beyond stroke boundary line, clash into time writer 140 and cause damage.Owing to adopting motor as drive unit, and electronic circuit and supply line etc. that checkout equipment uses all can produce interference electromagnetic wave.Disturb electromagnetic wave can cause that liquid crystal display 130 responds, and affects testing result.Therefore, the back up pad 120 in the utility model adopts antistatic plate, disturbs electromagnetic impact to shield.The electromagnetic performance of shielding of back up pad 120 is relevant with its thickness, and back up pad 120 is thicker, and screening ability is stronger; Back up pad 120 is thinner, and screening ability is more weak.In process of production, back up pad 120 adopts unified thickness conveniently to produce and to process.But the electromagnetic wave that time writer 140 is launched and interference electromagnetic wave all can shield by supported plate 140, therefore, track groove 126 is set in the utility model and reduces the electromagnetic impact that time writer 140 is launched.Track groove 126 is set, the transmitting terminal 141 of time writer 140 is positioned at track groove 126 all the time, due to being set, track groove 126 reduces back up pad thickness between transmitting terminal 141 and liquid crystal display 130, therefore, and not conductively-closed or only have sub-fraction conductively-closed of the electromagnetic wave that time writer 140 is launched.The electromagnetic wave of its transmitting still can be incident upon on liquid crystal display 130, meets detection needs.Therefore, in the time utilizing electromagnetic wave signal to detect liquid crystal display, the utility model both can shield and disturb electromagnetic impact, can complete smoothly again liquid crystal display and detect.
Detect multiple liquid crystal displays 130 because needs are extensive, the connector of wire and frequently pegging graft, pulling away joining connector on different liquid crystal displays, can damage after use a period of time.After damaging, need restringing.Restringing needs to open back up pad 120, to wire one end and the circuit arrangement that is positioned at cavity 111 are pegged graft.; because the utility model is all arranged on base, time writer, drive unit, gearing and guide piece on the lower surface 122 of back up pad 120; therefore; repeatedly opening, fasten in back up pad 120 processes; other devices are all opened, are fastened with back up pad 120, repeatedly open, can not cause in fastening process mutual alignment skew.
