The structure of the 1st conveyer 130 and the 2nd conveyer 140 is identical, for convenience of explanation, the structure of the 1st conveyer 130 only is described.As shown in Figure 7, the 1st conveyer 130 comprises: roughly dimetric framework 132 is arranged in the base portion 100; And bracket part 134, be installed in the two sides of framework 132, by transfer screw rod 110,110 ' rotating framework 132 is moved up and down, and with transfer screw rod 110,110 ' combine.

In addition, the automatic grasping device 150 of liquid crystal board comprises: transfer bed is transferred screw rod 152, is vertically installed in the right and left end of upper and lower member in the inboard of framework 132, distinguishes rotating freely by the driving of each drive source 154; Transfer bed carriage piece 156, it is combined into and can transfers screw rod 152 handovers along each transfer bed; A pair of up and down transfer bed 162, with about the end of transfer bed carriage piece 156 when combining, have a pair of stationary fixture 159 of only controlling liquid crystal board P at a distance of preset distance; Transfer bed displacement changeable mechanism 160 is installed in the two ends of each transfer bed 162, regulates the displacement at transfer bed 162 two ends; Testing agency 157 is installed on each anchor clamps 158,159, with the size that detects liquid crystal board P or dislocation; Control part (not shown) according to the detection signal of testing agency 157, is controlled the action of each drive source 154, transfers screw rod 152 to drive transfer bed respectively.

Transfer bed displacement changeable mechanism 160 is a roller bearing component, as shown in Figure 8, comprising: base portion 172, be arranged on the transfer bed carriage piece 156 that is installed on transfer bed 162 two ends, and, be arranged to one with transfer bed carriage piece 156; The turning axle 174 that combines with base portion 172; And the rotation that combines with roller 174 is with horizontal roller bearing 176.One in the transfer bed displacement changeable mechanism 160 at two ends also has: the straight line that is installed on the side of base portion 172 moves with horizontal roller bearing 173, and is clamped in the support bed 175 between base portion 172 and the turning axle 174.In addition, the structure that is installed in the transfer bed displacement changeable mechanism 160 on the transfer bed 162 up and down all is identical, just the position opposite of left and right sides transfer bed displacement changeable mechanism 160.

As shown in Figure 9, central portion in transfer bed 162 the insides, only has a pair of stationary fixture 158 at a distance of preset distance, be used for clamping and liquid crystal board P, and, have a pair of mobile anchor clamps 159 that can move along the anchor clamps guide rail 190 that the length direction on transfer bed 162 is installed in the left and right sides of stationary fixture 158.

Although testing agency 157 at length is not shown, be subjected to optical sensor and the photoelectric sensor of luminescence sensor all-in-one-piece more than 2, the upper and lower that preferably is arranged on panel is on each transfer bed 162 up and down.As other embodiment, break away from ground holding liquid crystal plate P up and down by being subjected to optical sensor and luminescence sensor, obviously, can detect the degree of misalignment of liquid crystal board P.In addition, at the periphery of liquid crystal board P, when dislocation takes place liquid crystal board P, also can use the touch sensor that contacts and produce electric signal with this liquid crystal board.

The automatic detecting devices panel bracket of the vertical-type of the present invention of said structure can automatically be controlled liquid crystal board P as described later.

When being mounted with the liquid crystal board P of new model on liquid crystal board supply unit 220, the control part input of operator in being located at testing fixture is with the relevant data of model of the liquid crystal board P of change.Whether the operator has been present in this control part according to the model data of the liquid crystal board P that is imported, changes the action of automatic detecting devices.

When the model data are not present in control part, when transferring transfer bed 162, detect liquid crystal board P by the testing agency 157 that is installed on the stationary fixture 158 by drive source 154.

When testing agency 157 fails to detect liquid crystal board P, control part (not shown) makes each drive source 154 action transfer screw rod 152 to drive transfer bed respectively, then, transfer bed is transferred screw rod 152 rotation respectively separately, and transfer bed carriage piece 156 and transfer bed 162 move towards the surface direction of liquid crystal board P.By transfer bed 162 near liquid crystal board P, simultaneously, if be installed on the face that testing agency 157 on a pair of stationary fixture 158 detects liquid crystal board P, then not dislocation, owing to be mounted with liquid crystal board P, control part stops the action of its drive source 154, so that stop the rotation that transfer bed is transferred screw rod 152.At this moment, the moving distance data of transfer bed 162 is sent to control part and is stored, so that use when later on the liquid crystal board P of same model is loaded into conveyer.Then, the mobile anchor clamps 159 by being installed on stationary fixture 158 both sides are respectively towards move left and right, are installed in the face that testing agency 157 on the mobile anchor clamps 159 detects liquid crystal board P.Be installed on testing agency 157 on the mobile anchor clamps 159 up to the moment that can not detect liquid crystal board P, obtain the width dimensional data of liquid crystal board P, and it is transferred to control part according to the displacement of mobile anchor clamps 159.Control part calculates the position of the mobile anchor clamps 159 of can be safely the liquid crystal board P that loads being controlled, and control signal is transmitted to the drive source 191 that is wholely set with mobile anchor clamps 159, and mobile anchor clamps 159 are moved towards preposition.When being arranged on the inner face of transfer bed 162, the end has driver 192, the 192 ' action of anchor clamps 158,159, stationary fixture 158 and mobile anchor clamps 159 forwards advance, and by controlling liquid crystal board P, finish controlling of liquid crystal board P.

Different with it, testing agency 157 on the stationary fixture 158 that is installed on a side detects liquid crystal board and the testing agency 157 of the opposing party's stationary fixture 158 when not detecting liquid crystal board, means that magnitude of misalignment is equivalent to the interval till liquid crystal boards detect in the testing agency 157 that does not detect liquid crystal board.In addition, owing to detect liquid crystal board the either party, so control part stops the action of drive source 154, so that stop the rotation that detected this transfer bed is transferred screw rod 152.Afterwards, by transfer bed displacement changeable mechanism 160, regulate the displacement at transfer bed 162 two ends.Promptly, rotation is installed with horizontal roller bearing 176 in the both sides of transfer bed 162, because on any of transfer bed 162 straight line being installed moves with horizontal roller bearing 173, therefore, when making drive source 154 action so that when only rotating any transfer bed and transferring screw rod 152, the transfer bed carriage piece 156 that moves the transfer bed handover screw rod 152 that stops to be axle, and a side's who fails to detect transfer bed carriage piece 156 descends, and misplaces to revise.Then, after being installed in mobile anchor clamps 159 on the transfer bed 162 as above-mentioned occasion and similarly moving,, finish controlling of liquid crystal board P by controlling liquid crystal board P with stationary fixture 158.

Data in operator's input have been present under the situation of control part, corresponding driving drive source 154 with these data, make transfer bed transfer screw rod 152 rotations, when regulating the displacement between the two ends, mobile transfer bed 162,2~5mm for example is arranged at the interval between the liquid crystal board P end of the end of anchor clamps 158,159 and loading.After transfer bed 162 was set, when being arranged on transfer bed 162 inner faces, the end has the driver action of anchor clamps 158,159, anchor clamps 158,159 forwards advanced, and control liquid crystal board P, finish controlling of liquid crystal board P.At this moment, so according to the result who is present in the data action of control part, when liquid crystal board P is not controlled reliably, for example liquid crystal board P is misplaced and is loaded and when making a part of anchor clamps can not control liquid crystal board P, all anchor clamps 158,159 are removed and are controlled, after transfer bed 162 returned to original position, the occasion that is not present in control part with the data of aforementioned input was similarly attempted controlling of liquid crystal board P once more.

For example, shown in Figure 10 A, when small-sized liquid crystal board P is not fed into framework 132 central of supply unit 220 with not misplacing, the any testing agency 157 of reason does not all detect liquid crystal board, when each transfer bed handover screw rod 152 rotates simultaneously so each drive source 154 up and down moves, each transfer bed 162 up and down moves to solid line position from a line position abreast with framework 132, afterwards, controls liquid crystal board P by anchor clamps 158,159.

Different with it, shown in Figure 10 B, when large-scale liquid crystal board P is not fed into the bottom of framework 132 of supply unit 220 with misplacing, because of upper detection mechanism 157 can not detect liquid crystal board, when a pair of drive source 154 action on top so that each transfer bed when transferring screw rod 152 and rotating simultaneously, top transfer bed 162 moves to solid line position from a line position abreast with framework 132, afterwards, controls liquid crystal board P by anchor clamps 158,159.

In addition, different with it, shown in Figure 10 C, when being fed into framework 132 central authorities of supply unit 220 to small-sized liquid crystal board P dislocation, cause any testing agency 157 does not up and down all detect liquid crystal board, each drive source 154 action up and down detect liquid crystal board so that each transfer bed handover screw rod 152 rotates simultaneously up to each testing agency 157.Then, when any testing agency 157 detects liquid crystal board, the rotation of the handover screw rod 152 that carries out this detection is stopped.Thus, the transfer bed carriage piece 156 that moves along handover screw rod 152 also stops.

Afterwards, the face up to another testing agency 157 detects liquid crystal board P makes another transfer bed carriage piece 156 descend correction dislocation, the angle θ thereby 162 of transfer beds stagger by transfer bed displacement changeable mechanism 160.So, after the transfer bed 162 of upper and lower all only rotated the angle that liquid crystal board P staggers, reason anchor clamps 158,159 were controlled liquid crystal board P, also can automatically control the liquid crystal board P that dislocation is loaded.

As mentioned above, will carry out as follows from the process that liquid crystal board supply unit 220 is transported to inspection portion 230 from the liquid crystal board P that secondary station is loaded on the panel bracket.

Embodiment 1

Will be the liquid crystal board P that controls of dislocation on the panel bracket be transported on the inspecting stand of inspection portion 230 with the dislocation state after, the data of the liquid crystal board P that dislocation is controlled transmit to control part.Control part transmits control signal to inspecting stand 232, inspecting stand 232 is corresponding with the dislocation of liquid crystal board on being loaded into panel bracket, receives the liquid crystal board under this state.Finish the inspection of liquid crystal board P at inspecting stand 232 after, the liquid crystal board of dislocation state keep intact by being held on the panel bracket, then, be transported to liquid crystal board supply unit 220.Afterwards, the data of loading the liquid crystal board that comes from the panel bracket dislocation are sent to control part, and to secondary station 250 transmission, secondary station 250 receives liquid crystal board according to the dislocation that is loaded into the liquid crystal board on the panel bracket to this control part with control signal.

Embodiment 2

The data of the liquid crystal board that dislocation is controlled on panel bracket are sent to control part, this control part is sent to control signal the drive source 154 of the 1st and the 2nd conveyer 130,140 of panel bracket, transfer the dislocation that transfer bed 162 is regulated in screw rod 152 rotations, the position of the liquid crystal board P that the recoverable dislocation is controlled by making each transfer bed that is connected with drive source 154.The liquid crystal board P that this is corrected is transported to inspection portion 230 from liquid crystal board supply unit 220, and, be loaded onto on the inspecting stand 232 of inspection portion 230, to check.Afterwards, check that the liquid crystal board that finishes under the state that has been corrected, is transported to liquid crystal board supply unit 220 once more from inspection portion 230, receive this liquid crystal board by secondary station 250.

In the above description, automatic detecting devices of the present invention with the panel bracket illustration vertical-type, but be not limited to this, for example adopt the automatic detecting devices panel bracket of horizontal type, the scope that does not exceed claim of the present invention equally, those of ordinary skills can carry out various variations in this scope.
