Generally, the first stopper 4158 and the second stopper 4159 are each provided in a cylindrical shape, so as to facilitate movement of the first stopper 4158 and the second stopper 4159 within the stopper hole 4157.

Example six

The main thickness gauge 332 is adjacent to the inner wall of the etched portion 33 and has a sliding structure to move to the vicinity of the outermost glass among the glasses vertically accommodated in the glass thinning jig 4, thereby facilitating detection of the glass thickness; specifically, under the control of the controller, the main thickness gauge 332 measures the thickness of the glass in real time by emitting a laser beam to the glass and transmits information about the measured thickness to the controller while the glass is undergoing a sliding process; the controller compares in real time a preset target thickness with the measured glass thickness received from the main thickness gauge 332. If it is determined that the measured glass thickness received from the main thickness gauge 332 reaches the target thickness, the controller stops operations such as thinning processing, and moves the glass thinning jig 4 along the unloading path.

Preferably, the main thickness gauge 332 may include: an emitter for emitting a laser beam; a receiver for receiving the light beam reflected by the glass; and an analyzer for analyzing the light beam received in the receiver and calculating a glass thickness.

The main thickness gauge 332 may further include an air injector for injecting air to a portion of the glass to be exposed to the laser beam emitted from the emitter. The main thickness gauge 332 controls the air injector for injecting air to a predetermined portion of the glass to be exposed to the laser beam and thus instantaneously removing the shower liquid before the laser beam is emitted by the emitter, so that more accurate glass thickness measurement data can be obtained.

Generally, the target thickness is a theoretical thickness value of the glass required after the thinning process, and the theoretical thickness value is a range value with a tolerance.

The glass thinning production line further comprises a first auxiliary thickness gauge which is arranged in the unloading channel and used for measuring the thickness of the thinned glass again, and the first auxiliary thickness gauge sends the measured thickness of the glass to the controller. The first auxiliary thickness gauge may reduce the defect of glass thinning caused by malfunction of the main thickness gauge 332 or abnormal operation when the blocking factor in the etched portion 33 cannot correctly measure the thickness of glass, where the blocking factor may be spraying blocking of the spraying liquid or vibration of the glass thinning jig 4.

The controller determines whether the thinning process is normally performed in the etched portion 33 or whether the main thickness gauge 332 is properly operated based on the glass thickness measured by the first auxiliary thickness gauge. In general, the controller determines that the main thickness gauge 332 cannot function properly or that the thinning process is not performed normally in the etched portion 33 if the thickness of the glass received from the first auxiliary thickness gauge is out of the tolerance range of the target thickness. In this case, the controller issues an alarm to notify the manager that the main thickness gauge 332 is malfunctioning or that the thinning process in the etched portion 33 is abnormal.

Failure of the main thickness gauge 332 or a thinning process anomaly in the etched portion 33 may be temporary; the controller may control the glass thinning jig 4 to return to the etching part 33 again when the glass thickness received from the first auxiliary thickness gauge exceeds the tolerance range of the target thickness, and control the glass to undergo thinning processing again in the etching part 33 to process the glass to the target thickness.

If the measured glass thickness is within the tolerance range of the target thickness, the controller controls the removal of the glass thinning jig 4 accommodating the glass that has undergone the thinning process again, and then loads the next glass thinning jig 4 accommodating the glass to be subjected to the thinning process into the etching region 3 through the loading passage.

The glass thinning production line further includes a second auxiliary thickness gauge that may be disposed in the loading channel for measuring in advance a thickness of glass to be subjected to a thinning process and transmitting information about the measured thickness to a controller.

The thickness of the glass to be subjected to the thinning process is measured in advance by the second auxiliary thickness gauge, and compared with the initial thickness detected by the main thickness gauge 332, it can be determined whether the main thickness gauge 332 is malfunctioning, so that it is determined whether the chamber 331 needs to be re-entered at a later stage according to the detection data of the first auxiliary thickness gauge. Specifically, when the detected thickness of the second auxiliary thickness gauge and the initial detected thickness detected by the main thickness gauge 332 are not within the tolerance range, it may be determined that the main thickness gauge 332 is malfunctioning; when the detected thickness of the first auxiliary thickness gauge does not meet the target thickness at a later stage, it may be determined that the main thickness gauge 332 is not temporarily malfunctioning, and the controller alarms to remind not to withdraw the glass thinning jig 4 into the chamber 331 any more, withdraw the glass thinning jig 4 from the etching region, and wait for the maintenance of the main thickness gauge 332 to be completed.

Example seven

The specific process flow of the glass thinning production line comprises the following steps:

s1, placing the glass thinning jig 4 vertically accommodating glass in the conversion area 1, transferring to the etching area 3 after being cleaned before being thinned by the flushing area 2 through the conversion area 1, enabling the glass thinning jig 4 to enter the etching part 33 along the loading channel in the etching area 3, and performing thinning treatment in the etching area 3;

Specifically, during the thinning process in the etching section 3, the controller controls the glass thinning jig 4 to reciprocate within the etching section 33, and the main thickness gauge 332 measures the glass thickness and transmits information about the measured thickness to the controller in real time; when the measured glass thickness reaches a preset target thickness, the controller stops the thinning process of spraying the shower liquid in the etching portion 33, and controls the glass thinning jig 4 to be taken out through the unloading passage.

In general, in the chamber 331, the specific process parameters of the thinning process are: the one-way time of a single pass in the reciprocating motion of the glass thinning jig 4 is set to be 1.5 s-4 s, the one-time reciprocating time is set to be 3 s-8 s, and the reciprocating motion amplitude is set to be about 180 mm; the flow rate of the spray liquid controlled by the spray system is set to 1500-2400 LPM, and the acid etching temperature in the chamber 331 is generally set to 20-40 ℃; under the parameters, the acid etching rate of the glass is generally 2.0-7.0 mu m/min, and the whole thinning treatment of the glass can be effectively realized.

S2, the glass thinning jig 4 subjected to thinning treatment stands by in the loading channel, and the controller performs first thinning thickness confirmation operation;

specifically, the thickness-reduction confirmation operation is implemented by comparing the detected thickness by the first auxiliary thickness measuring instrument disposed in the unloading channel with the second auxiliary thickness measuring instrument disposed in the loading channel, and when the reduced thickness does not reach the target thickness, the controller may control the glass-reduction jig 4 to retract into the chamber 331 again for re-reduction treatment.

S3, moving the glass thinning jig 4 to the flushing area 2 through the conversion area 1, and performing a second thinning thickness confirmation operation by the controller after the flushing area 2 is thinned and cleaned;

Specifically, the thickness detection is performed by the third auxiliary thickness measuring apparatus disposed in the flushing area 2, so as to implement the thickness reduction confirmation operation, and when the thickness reduction does not reach the target thickness, the glass reduction jig 4 may enter the etching area 3 again through the conversion area 1 to perform the thickness reduction treatment.

The main thickness gauge 332 is provided in the etching part 33 in which the thinning process is applied to the glass and measures the glass thickness in real time so that the glass can have a target thickness more accurately; the first auxiliary thickness gauge is additionally provided in the unloading passage and again measures the thickness of the glass subjected to the thinning process, so that it is possible to check whether the main thickness gauge 332 provided in the etched part 33 is not operated properly and to minimize the defect rate of the thinned glass; the second auxiliary thickness gauge is additionally provided in the loading passage and measures the thickness of the glass to be subjected to the thinning process in advance, so that it is possible to check whether the main thickness gauge 332 provided in the etching zone 3 cannot operate properly; the third auxiliary thickness measuring instrument is arranged in the flushing area 2, so that after the glass is thinned and cleaned, thickness detection is performed again, whether the glass which is carried out from the glass thinning production line in advance meets the standard is detected, and the defect rate of the thinned glass is further reduced.
