Thing.
The present embodiment sets liftable Weighing mechanism in the gap between transfer roller, so as on a production line
It can judge that substrate whether there is mass defect by gravity detection, to ensure that person skilled can be solved in time
Problem.
The base plate transfer device operation principle of the present invention is described in detail with reference to a practical application.
Assuming that the transporting substrates, device of the present invention is set to a processing node on array base palte production line, substrate to be detected exists
Related processing is carried out on the processing node.
As shown in Figures 2 and 3, the transfer roller 11 of the present embodiment is responsible for driving by an actuating unit 7.When substrate 6 to be detected
After reaching Working position by transfer roller 11, now Weighing mechanism 2 is in holding state, after substrate 6 to be detected is stable, waits and claiming
Re-detection.
Under normal condition before detection of weighing, it is assumed that the lifting height of elevating mechanism 3 now is h1, and Weighing mechanism 2 should
Less than the support surface that transfer roller 11 is directed to substrate 6 to be detected, i.e., substrate 6 to be detected is supported by transfer roller 11 completely.
When testing process is weighed in execution, as shown in figure 4, the elevating mechanism 3 of controlling organization 4 is begun to ramp up, reach target height
After spending h2, Weighing mechanism 2 is caused to hold up substrate 6 to be detected completely, so as to measure the weight data of substrate 6 to be detected.
Weighing mechanism 2 transmits weight data is obtained to processing mechanism 5 afterwards, by processing mechanism 5 according to pre-setting
The one intact due weight of substrate institute, is contrasted with the weight data got, so that it is determined that substrate to be detected 6 is
It is no to occur broken or residue be present.
If processing mechanism 5 determines that substrate to be detected has no problem, controlling organization 4 controls elevating mechanism 3 to drop to Fig. 3 institutes
The height h1 shown so that substrate 6 to be detected is put back on transfer roller 11.
Conversely, if processing mechanism 5 determines that substrate to be detected is problematic, to avoid sending substrate 6 to be detected to production line
Upstream device, then controlling organization 4 can close the actuating unit 7 that driving transfer roller 11 is rotated, and wait operator
Member is handled.
Certainly, for above-mentioned application scenarios, the weight detecting in the present embodiment can be carried out before substrate is processed, can also
Carried out after substrate processing.Detected before processing, then relevant device can be prevented to make problematic substrates, so as to keep away
Exempt from waste of resource.Detected, then the manufacture craft of this node can be checked, and avoid defective product quilt after processing
It is sent to upstream device.

It is (exemplary that the weight data that one first weighing unit 21 is got and the ratio of the first expected value are more than 0.05% to 0.1%
Numerical value), it is determined that substrate disorder to be detected;Second control unit, for the weight got when any second weighing unit 22
When data and the ratio of the second default value are more than 0.15% to 0.2% (exemplary value), it is determined that substrate disorder to be detected.
As exemplary introduction, it is assumed that a residue 10 as shown in Figure 5 on substrate to be detected be present, then the lower right corner
Second weighing unit 22 measures weight data and is greater than the standard figures that the second control unit is pre-set, and now the second control is single
It is first then actuating unit 2 can be closed in time.
It can be seen that the preferred scheme of above-mentioned Weighing mechanism, allows the second weighing unit in center section to undertake base to be measured
Most of weight of plate, so as to reduce the numerical value of weighing of first weighing unit at four angles, and it is further on this basis
For the first weighing unit, the higher evaluation criteria (that is, smaller amount of deflection standard) of accuracy is set, it is even to be detected
There are slight breakage or residue in four angles of substrate, also can accurately be identified.
In addition, to avoid elevating mechanism during rise, there is shake, causes position to shift in substrate to be detected,
Preferably, the supporting surface that each first weighing unit 21 is used to hold up substrate to be detected is L-type, does not have the second weighing unit
22 supporting surfaces for being used to hold up substrate to be detected are round, are treated by the supporting surface of the first weighing unit L-type with more steady hold up
Detect substrate 6.
