Hold above-mentionedly, pulley blocks 130 comprises an axostylus axostyle 134, a bracing frame 136 and a pulley 138.Axostylus axostyle 134 wears the horizontal part 124 of pedestal 120, and bracing frame 136 is fixed in an end of axostylus axostyle 134, and pulley 138 is articulated in bracing frame 136.When substrate 50 transports along first direction D1 by transporting platform 110, pulley 138 is contacted with substrate 50 and is driven and rotate by substrate 50.So, when substrate 50 when being smooth, pulley 138 can be contacted with substrate 50 and one side and rotate and do not influence substrate 50 and transporting transporting on the platform 110.
Front-view schematic diagram when Fig. 3 detects the substrate out-of-flatness for the substrate detection apparatus of Fig. 2.What illustrate among Fig. 3 is that substrate 50a is irregular situation.When an irregular substrate 50a is transported transporting platform 110 along first direction D1, pulley blocks 130 is contacted with substrate 50a.Particularly, because the out-of-flatness of substrate 50a, when substrate 50a advanced along first direction D1, its protruding 52a can push against pulley blocks 130, and pulley blocks 130 is had along the displacement of second direction D2 along the profile of substrate 50a.In the present embodiment, it is close that this displacement makes pulley blocks 130 relative pedestals 120.Further, first electrical contact 132 that is arranged on pulley blocks 130 separates with second electrical contact 144 and circuit loop opens circuit.
Hold above-mentionedly, whether the substrate detection apparatus 100 of present embodiment is to utilize first electrical contact 132 and second electrical contact 144 whether contacting between the two to decide the out-of-flatness sensing signal to produce.And when the circuit loop generation of opening circuit, processing unit 142 can send out-of-flatness sensing signal display base plate 50a out-of-flatness, and the operating personnel of substrate detection apparatus 100 just can take off irregular substrate 50a by transporting platform 110.Perhaps substrate detection apparatus 100 can be done with other automation equipments and be connected, and when processing unit 142 sends signal display base plate 50a out-of-flatness, automation equipment such as mechanical arm can take off to avoid successive process to have problems by transporting platform 110 substrate 50a.
Please refer to Fig. 3, specifically, as the irregular protruding 52a of pulley 138 by substrate 50a, protruding 52a pushing and pressing pulley 138 makes pulley 138 drive bracing frame 136 and axostylus axostyle 134 makes first electrical contact 132 separate with second electrical contact 144 near pedestal 120 along second direction D2 relatively.In the present embodiment, pulley blocks 130 can comprise a slide rail (not illustrating), and pedestal 120 can comprise a chute (not illustrating), and pulley blocks 130 is slidingly installed in pedestal 120 along second direction D2.When pushing against as pulley 138 contact projection 52a and by it, pulley blocks 130 slides and close pedestal 120 along second direction D2, and first electrical contact 132 is separated with second electrical contact 144.
In addition, in the present embodiment, substrate detection apparatus 100 more comprises an elastic component 150, and for example spring is sheathed on outside the axostylus axostyle 134.Elastic component 150 is between pulley blocks 130 and pedestal 120, and the one end is connected in the horizontal part 124 of pedestal 120, and the other end is connected in the bracing frame 136 of pulley blocks 130.As illustrating among Fig. 3, when substrate 50a is the out-of-flatness state, pulley blocks 130 can along the relative pedestal 120 of second direction D2 near and compression elastic piece 150, and in the process of compression the storage elasticity potential energy.When irregular substrate 50a takes off by transporting platform 110, the elasticity potential energy of elastic component 150 discharges and pulley blocks 130 is returned to as the position among Fig. 2.So, substrate detection apparatus 100 can continue to detect other by transporting the substrate (not illustrating) that platform 110 transports.In simple terms, the setting of elastic component 150 is in order to allow first electrical contact 132 keep contacting of normality with second electrical contact 144.
It should be noted that at this circuit loop of first electrical contact 132, second electrical contact 144 and processing unit 142 can form a normality short circuit or normality opens circuit.Particularly, if circuit loop is when the normality short-circuit condition, first electrical contact 132 forms normality with second electrical contact 144 and contacts, to make pulley blocks 130 when relatively producing displacement away from the second direction D2 of substrate 50a as irregular substrate 50a, first electrical contact 132 and second electrical contact 144 are separated from each other and form and open circuit, at this moment, processing unit 142 will produce the out-of-flatness sensing signal according to off state.What in other words, the embodiment of Fig. 2 and Fig. 3 illustrated is the example of normality short circuit.
Fig. 4 is the schematic perspective view of a kind of substrate detection apparatus of another embodiment of the present utility model.Fig. 4 continues to use element numbers and the partial content of Fig. 2, wherein adopts identical label to represent identical or approximate element, and has omitted the explanation of constructed content.Explanation about clipped can no longer repeat to give unnecessary details in this with reference to previous embodiment.The difference of the embodiment of Fig. 4 and the embodiment of Fig. 2 is that mainly the embodiment of Fig. 4 is the example that a kind of normality opens circuit.
Please refer to Fig. 4, when the formation state of substrate 50 for illustrating among Fig. 4, the first electrical contact 132a can keep with the second electrical contact 144a and separate.Specifically, in the embodiment of Fig. 4, the second electrical contact 144a position is above the first electrical contact 132a, and the spacing of being separated by between the first electrical contact 132a and the second electrical contact 144a, makes both keep separation.Please then refer to Fig. 5, when the out-of-flatness state of substrate 50a for illustrating in as Fig. 5, when pulley blocks 130a touched protruding 52a, pulley blocks 130a upwards slided along second direction D2, made to be configured in the second electrical contact 144a that the pulley blocks 130a first electrical contact 132a touches the top.
That is to say, in the present embodiment, if circuit loop is when the normality off state, the first electrical contact 132a forms normality with the second electrical contact 144a to be separated, to make pulley blocks 130a when relatively producing displacement away from the second direction D2 of substrate 50a as irregular substrate 50a, the first electrical contact 132a and the second electrical contact 144a are in contact with one another and form short circuit, and at this moment, processing unit 142 will produce the out-of-flatness sensing signal according to short-circuit condition.
Fig. 6 is the schematic perspective view of a kind of substrate detection apparatus of another embodiment of the present utility model.Fig. 6 continues to use element numbers and the partial content of Fig. 2, wherein adopts identical label to represent identical or approximate element, and has omitted the explanation of constructed content.Explanation about clipped can no longer repeat to give unnecessary details in this with reference to previous embodiment.The difference of the embodiment of Fig. 6 and the embodiment of Fig. 2 is that mainly the embodiment of Fig. 6 does detection wirelessly.Or say that the embodiment of Fig. 6 makes sense process device 140 further produce irregular sensing signal in the noncontact mode, and the embodiment of Fig. 2 makes sense process device 140 further produce irregular sensing signal with the way of contact.
