[0002] At present, existing smart phones all have IR (infrared ray) sensing function. In order to cooperate with the IR sensing function, an IR hole is generally set on the glass cover of the touch screen, and IR ink is screen-printed on the IR hole to selectively transmit infrared light, thereby reducing the interference of other unnecessary light; an important parameter for whether the IR ink printing meets the standard is the transmittance. How to effectively and conveniently detect the transmittance of IR ink is an issue that industry insiders need to consider.

[0003] The traditional detection method is generally carried out manually, which manually places the glass to be tested on the IR hole transmittance tester, and then manually aligns the IR hole position of the glass with the IR hole transmittance tester, so that the IR hole transmittance tester can detect the transmittance of the IR hole position of the glass; however, its structural design is poor, and it is difficult for manual operation to accurately locate the IR hole position of the glass and the IR hole transmittance tester and align the light beam, which is easy to cause false detection and missed detection, and the eyes of the personnel are easily fatigued, and the test efficiency is low. When the glass is tested with a protective film, manual operation is more prone to the above problems and wrong judgments, the operation is cumbersome, and the use is inconvenient, which reduces the IR hole detection efficiency of the glass.

Step 3: The pick-up fixture with the workpiece is controlled by the four-axis manipulator to lower the workpiece onto the transfer platform. The transfer platform is moved to the bottom of the CCD vision device under the control of the XY direction displacement module. The CCD vision device identifies the IR hole position of the workpiece in the area to be inspected and feeds back the position information to the PLC, the industrial control host computer device and the display; Step 4: The transfer platform moves toward the IR hole transmittance tester through the control of the XY direction displacement module, and accurately moves each IR hole of the workpiece to the light line of the IR hole transmittance tester one by one according to the position information fed back by the PLC and the industrial control host computer device, so that the test light passes through the IR hole, thereby obtaining the transmittance result of the IR hole, and feeding it back to the PLC and the industrial control host computer device; Step five, the transfer platform is reset through the control of the XY direction displacement module, and the four-axis manipulator controls the film picking fixture to move toward the transfer platform so that the film picking fixture can grab the workpiece after inspection. Then, the four-axis manipulator moves the film picking fixture to the first discharging area or the second discharging area according to the inspection result feedback from the PLC and the industrial control host computer device, and places the workpiece on the corresponding discharging assembly line.
