DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0026] like Figure 1-Figure 7As shown, the automated testing system for edge defect detection and size measurement of ultra-thin flexible glass proposed by the present invention includes a base 1, a top shell 2 is provided on the base 1, a marble platform 3 is provided on the top side of the base 1, the function of the marble platform 3 is to ensure the overall flatness of the equipment, a transport component 7 is provided on one side of the marble platform 3, a mounting frame 4 is provided on the marble platform 3, a pair of test components 6 are provided on one side of the mounting frame 4, a platform component 8 to be tested and a detection component 9 are provided in the test component 6, a moving component 81 and a flattening component 86 are provided in the platform component 8 to be tested, and the function of the moving component 81 is to allow the product to be tested 816 to move in the directions of the X-axis and the Y-axis, so that the detection component 9 completes the defect detection and size measurement of the product to be tested 816.

[0027] The moving assembly 81 includes a Y-axis moving module 811 set on the marble platform 3. The function of the Y-axis moving module 811 is to complete the movement in the Y-axis direction, with an absolute positioning accuracy of ±2 microns, to ensure the accuracy of the device size measurement. The Y-axis moving module 811 is provided with an X-axis moving module 812. The function of the X-axis moving module 812 is to complete the movement in the X-axis direction, with an absolute positioning accuracy of ±2 microns, to ensure the accuracy of the device size measurement. The X-axis moving module 812 is provided with a mounting platform 817.

[0028] A plane light source 814 is provided in the middle of the mounting platform 817. The plane light source 814 can emit strong light to make the edge defects of the product under test 816 clearer in the camera's field of view, which is more conducive to defect detection. Several columns 818 are provided around the mounting platform 817. A glass platform 813 is provided on the top of several of the columns 818. A vacuum platform 815 is provided in the middle of the glass platform 813. The product under test 816 is provided on the vacuum platform 815. The product under test 816 is first placed on the glass platform 813, and then the vacuum platform 815 in the middle of the glass platform 813 vacuum-adsorbs the product under test 816 to ensure that the product under test 816 remains in position without displacement during the detection process.

[0029] The flattening assembly 86 includes a pair of vertical ears 864, the two vertical ears 864 are symmetrically arranged on one side of the mounting platform 817, a fixed shaft 865 is movably arranged between the two vertical ears 864, and a bearing seat 866 is arranged at both ends of the fixed shaft 865. A T-axis reducer 863 and a T-axis servo motor 862 are arranged on one side of the fixed shaft 865. A glass cover 861 is arranged on the fixed shaft 865. The function of the glass cover 861 is to flatten the product 816 to be tested when it is placed on the glass platform 813. It is flexible and may be uneven, so a glass cover plate 861 is needed to flatten the product under test 816 to ensure that the product under test 816 is in a flat state, making the size detection more accurate. The T-axis servo motor 862 alone cannot drive the fixed shaft to rotate so that the glass cover plate 861 can complete the closing action. Therefore, a T-axis reducer 863 with a reduction ratio of 1:50 is required to increase the torque. The T-axis servo motor 862 drives the T-axis reducer 863 to generate rotational motion, driving the fixed shaft to rotate, so that the glass cover plate 861 can complete the closing action.

[0030] The detection component 9 includes a Z-axis moving module 91 arranged on the mounting frame 4. The Z-axis moving module 91 is driven by the internal Z-axis servo motor to complete the movement in the Z-axis direction. A 1200W camera 93 is arranged on one side of the Z-axis moving module 91, and a telecentric lens 94 is arranged at the bottom of the 1200W camera 93. The 1200W camera 93 and the telecentric lens 94 are used in combination to realize edge defect detection and size measurement of the product under test 816. A ring light source 95 is arranged at the position of the telecentric lens at the bottom of the Z-axis module. The ring light source 95 emits strong light to make the image of the product under test 816 clearer. The product under test 816 and the telecentric lens 94 need to be at a fixed distance, that is, 110 mm, to make the image of the product under test 816 clearest. Therefore, the Z-axis moving module 91 is required to ensure that the product under test 816 and the telecentric lens 94 always maintain a fixed distance.

[0031] The transport assembly 7 includes a mounting frame 2 76 provided on the base 1. A transport linear module 71 is provided on the top of the mounting frame 2 76. The transport linear module 71 can move horizontally to complete the transport action of the tested product 816. The tested product 816 is transported from the previous machine to the present device. After the test is completed, the tested product 816 is transported from the present device to the next machine. A loading lifting module 72 is slidably provided on the transport linear module 71. The function of the loading lifting module 72 is to raise the tested product 816 to a safe height during the transport process to avoid interference. The loading lifting module 72 is used for loading. A loading suction cup 73 is provided on one side of the bottom. The function of the loading suction cup 73 is to vacuum absorb the product 816 to be tested, and is used for transporting and loading. A unloading lifting module 74 is provided on one side of the loading lifting module 72. The unloading lifting module 74 is slidably set on the transport linear module 71. The function of the unloading lifting module 74 is to raise the product 816 to a safe height during the transport process to avoid interference, and is used for unloading. A unloading suction cup 75 is provided on one side of the bottom of the unloading lifting module 74. The function of the unloading suction cup 75 is to vacuum absorb the product 816 to be tested, and is used for transporting and unloading. The loading suction cup 73 and the unloading suction cup 75 are on the same side.

[0032] When in use, the staff starts the automated testing equipment for edge defect detection and size measurement of ultra-thin flexible glass. The transport linear module 71 in the transport component 7 drives the loading lifting module 72 to move horizontally. The loading suction cup 73 in the loading lifting module 72 vacuum absorbs the upstream incoming material, that is, the product to be tested 816. After the loading lifting module 72 raises the product to be tested 816 to a safe height, the transport linear module 71 drives the loading lifting module 72 to move horizontally to directly above the platform component 8 to be tested. The loading lifting component descends and places the product to be tested 816 on the glass platform 813. The vacuum platform 815 in the middle of the glass platform 813 vacuum absorbs the product to be tested 816 to complete the handover of the product to be tested 816.

[0033] The T-axis servo motor 862 drives the T-axis reducer 863 to rotate the fixed shaft 865, thereby completing the closing action of the glass cover 861 and flattening the product under test 816, ensuring that the product under test 816 is in a flat state, making the detection more accurate. The Y-axis moving module 811 and the X-axis moving module 812 drive the mounting platform 1 817 to move to the bottom of the telecentric lens 94. The Z-axis moving module 91 in the detection component 9 moves up and down to maintain a fixed distance of 110 mm between the telecentric lens 94 and the product under test 816. The annular light source 95 at the bottom of the Z-axis moving module 91 and the plane light source 814 on the mounting platform 1 817 make the image of the product under test 816 clearer.

[0034] After the inspection is completed, the Y-axis moving module 811 and the X-axis moving module 812 drive the installation platform 817 to move to the vicinity of the transport component 7, and the T-axis servo motor 862 drives the T-axis reducer 863 to rotate it, so that the glass cover 861 is opened, and the transport linear module 71 drives the unloading lifting module 74 to move horizontally to just above the installation platform 817. The unloading lifting module 74 drives the unloading suction cup 75 to descend, and vacuum absorbs the product to be tested 816. After the unloading lifting module 74 raises the product to be tested 816 to a safe height, the transport linear module 71 drives the unloading lifting module 74 to move horizontally, and transports the product to be tested 816 to the next equipment to complete the unloading. By setting up a pair of test components 6, when the first test component 6 is unloading and loading, the second detection component 9 is in the detection state. When the second test component 6 is unloading and loading, the first test component 6 is in the detection state. This cycle is repeated to improve work efficiency.
