In step 100, the PSH value is a height value of the spacer on the color filter substrate. The detection of the PSH detection equipment comprises an identification module, wherein the identification module is used for identifying a first substrate ID on the color film substrate so as to report the PSH value and the corresponding first substrate ID to the control system.
In an embodiment, the PSH detection apparatus first selects at least two detection points on the color filter substrate, then detects a PSH value of each detection point, and finally calculates an average PSH value of all the detection points as a PSH value of the color filter substrate.
In this embodiment, the position of each detection point may be preset by a technician according to actual needs, and each detection point may be evenly distributed on the entire large color filter substrate or may be biased to a certain area of the large color filter substrate.
The color film substrate and the array substrate are generally attached in a large plate form, and are cut to form individual small liquid crystal panels after the large plate is attached. In the device linkage method, the color film substrate comprises a large glass, and M × N independent color film units are distributed on the large glass in an array manner, wherein M and N are positive integers, and M is larger than N.
In addition to the PSH values detected and calculated by the foregoing embodiments, in another embodiment, the PSH detecting apparatus first selects at least two detection points in each color film unit of the color film substrate, then detects the PSH value of each detection point, then calculates an average value of the PSH values of all the detection points in each color film unit as the PSH value of the color film unit, and finally calculates an average value of the PSH values of all the color film units as the PSH value of the color film substrate.
Similarly, in this embodiment, the positions of the detection points may be preset by a technician according to actual needs, and the number of the detection points in different color film units may be the same or different, even if there are no detection points in some color film units.
The control system comprises a Defect File System (DFS), an Equipment Automation System (EAS) and a production execution manufacturing system (MES), when the PSH value of the color film substrate is reported to the control system, the PSH detection unit firstly reports the PSH value and the first substrate ID of the color film substrate to the Defect File System (DFS) through an FTP protocol, and then the Defect File System (DFS) reports the PSH value and the first substrate ID of the color film substrate to the production execution manufacturing system (MES) through a TIBRV protocol.
Step 200: and monitoring the color film substrate by using a liquid crystal dropping device, and requesting a PSH value corresponding to the color film substrate from the control system when the color film substrate is monitored.

When a PSH value corresponding to the color film substrate is requested from the control system, the liquid crystal dropping device reports a first substrate ID and a request instruction on the color film substrate to the equipment automation system EAS through a CC-Link protocol, then the equipment automation system EAS reports the first substrate ID and the request instruction on the color film substrate to the production execution manufacturing system MES through a TIBRV protocol, and finally the production execution manufacturing system MES finds the corresponding PSH value according to the reported first substrate ID and then issues the PSH value to the equipment automation system EAS through the TIBRV protocol.
If the corresponding PSH value is not found by the manufacturing execution system MES according to the reported first substrate ID, that is, the color filter substrate requesting the PSH value (during the sampling inspection) is not detected by the PSH detection device, the average value of the PSH values corresponding to all other first substrate IDs in the same batch as the first substrate ID is calculated, and the average value is used as the PSH value (of the color filter substrate) corresponding to the first substrate ID and then issued to the EAS.
Step 300: the liquid crystal dropping device monitors the array substrate, when the array substrate is monitored, one-to-one corresponding laminating relation between the color film substrate and the array substrate is formed, and the formed laminating relation is reported to the control system.
When the array substrate is conveyed into the liquid crystal dropping device by the sorting and conveying device, an indexer on a loading unit of the liquid crystal dropping device is also triggered, and then the ID of the second substrate on the array substrate is obtained.
In this step 300, when the array substrate reaches the cleaning unit in the liquid crystal dropping device, the liquid crystal dropping device reports the second substrate ID on the array substrate and the first substrate ID of the color film substrate to the control system after forming a one-to-one correspondence relationship therebetween.
When the formed bonding relationship is reported to the control system, the liquid crystal dropping device reports the first substrate ID and the second substrate ID which are correspondingly bonded to the equipment automation system EAS through the CC-Link protocol, and then the equipment automation system EAS reports the first substrate ID and the second substrate ID which are correspondingly bonded to the defect file system DFS through the TIBRV protocol, and the PSH value which is issued by the manufacturing execution system MES and corresponds to the first substrate ID in step 200.
Step 400: and the control system calculates the liquid crystal dropping amount required by the array substrate according to the reported laminating relation and the requested PSH value corresponding to the color film substrate.
In step 400, when the control system calculates the liquid crystal dropping amount required by the array substrate, the defect file system DFS calculates the liquid crystal dropping amount required by the array substrate according to the reported first substrate ID and second substrate ID corresponding to the bonding, and the PSH value corresponding to the first substrate ID issued by the manufacturing execution system MES in step 200, and generates a file to store the file on the designated path.
The liquid crystal dropping amount required for calculating the PSH value of the color film substrate is related to the prior art, and is also related to the type, the process and the like of the array substrate besides the PSH value of the color film substrate, and the calculation formulas used by various manufacturers are also different, and are not limited specifically here.
Step 500: the liquid crystal dropping equipment acquires the liquid crystal dropping amount required by the array substrate from the control system, and drops the corresponding liquid crystal amount on the array substrate according to the acquired liquid crystal dropping amount.
In this step 500, when the array substrate reaches the drop unit in the liquid crystal drop device, the liquid crystal drop device finds a file corresponding to the array substrate in a specified path of the defect file system DFS, and further obtains a liquid crystal drop amount required by the array substrate.
Step 600: and the liquid crystal dropping equipment relatively sticks the array substrate dropped with the liquid crystal and the corresponding color film substrate according to the formed sticking relation.
In this step 600, when the array substrate reaches the attaching unit in the liquid crystal dropping device, the liquid crystal dropping device attaches the array substrate to the corresponding color film substrate relatively.
After the array substrate and the color film substrate are attached to form the large panel, the large panel can be sent to a panel cutting device for cutting, so that a plurality of independent liquid crystal panels are formed.
The device linkage method links the PSH detection device, the liquid crystal dropping device and the control system to automatically calculate the liquid crystal dropping amount required by the corresponding array substrate according to the PSH value of each color film substrate, so that the automatic compensation of a liquid crystal dropping process is realized, the production efficiency is greatly improved, the labor is saved, and the product yield is improved.
