Description

Technical Field

[0001] This disclosure relates to the field of A-frame testing, and more specifically, to a testing device for glass-mounted A-frames used in optoelectronic displays. Background Technology

[0002] A-frames, used for transporting optoelectronic display glass, serve as the carriers for this purpose. During transport, the glass needs to be loaded onto these A-frames. Due to the large number of A-frames used and the varying sizes of optoelectronic display glass, the dimensions of the A-frames must be adjusted accordingly. This is especially problematic for larger A-frames, where manual inspection becomes difficult, leading to measurement errors and uncontrollable flatness of the back and bottom plates. An uneven bottom plate can cause uneven stress on the glass during loading, resulting in breakage. An uneven back plate can cause significant thickness differences at the four corners, leading to uneven stress on the glass during packaging, among other issues.

[0003] The current testing methods all involve manual measurement using a ruler and height gauge with standard parts. Since there are many measurement points for A-frames with large structures, manually moving the measuring tools back and forth to take measurements can easily lead to errors. Even with multiple people cooperating in the testing, measurement mistakes are unavoidable.

[0004] How to accurately detect the flatness of the back panel and bottom panel of the A-frame is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this disclosure is to provide a testing device for glass mounting A-frames for optoelectronic displays. This device detects the flatness of the back plate and bottom plate of the A-frame by changing the positions of the first and second testing scales. It eliminates the need for manual measurement with measuring tools, making it convenient and quick, and improving measurement quality and testing efficiency.
