Description

Technical Field

[0001] The invention relates to the field of ultra-thin glass production, and in particular to an air permeability detection device and a detection method for mildew-proof roll paper for glass stacking. Background Art

[0002] At present, ultra-thin electronic glass needs to be isolated with mildew-proof paper during the stacking process to prevent the glass from deteriorating or being contaminated. Figure 1 As shown, the isolation paper between the stacked glasses needs to cover the upper surface of the glass during the online transmission process, and then be grabbed by the robot's suction cup gripper and neatly stacked on the shelf. The suction cup can normally grab the ultra-thin electronic glass with the paper, and the roll paper used is required to have sufficient air permeability. If the air permeability of the roll paper is poor, only a good negative pressure can be formed between the suction cup and the paper, but a good negative pressure cannot be formed between the isolation paper and the glass. The robot is prone to abnormal sheet drop during the stacking process, so it is very important to measure the air permeability of the arriving roll paper in advance. Summary of the invention

[0051] Embodiment 2:

[0052] The detection method of the air permeability detection device for the mildew-proof roll paper for glass stacking comprises the following steps:

[0053] 1) Feed the anti-mildew roll paper from the paper feeding end of the table panel 1, so that the anti-mildew roll paper passes under the paper plate 21;

[0054] 2) Manually pull the end of the anti-mildew roll paper until it passes through the paper feed roller 18;

[0055] 3) Open the second stop valve 13 and ensure that the first stop valve 12 is closed, and the negative pressure tank 9 is pumped out negative pressure through the negative pressure pump 11;

[0056] 4) When the pressure value on the digital pressure gauge 14 reaches a preset negative pressure value (e.g. -1 bar), close the second stop valve 13;

[0057] 5) The first stop valve 12 is opened by the controller 15, and the motor 20 is started at the same time to perform a continuous air permeability test on the mildew-proof paper roll.

[0058] In the preferred embodiment, in the step 5), the controller 15 opens the first stop valve 12 and starts the timer 16 at the same time, the digital pressure gauge 14 transmits the real-time pressure value to the controller 15, which is displayed on the display screen 17 after signal conversion, and the timer 16 transmits the time signal to the controller 15, which is displayed on the display screen 17 after signal conversion.
