Description

Technical Field

[0001] This utility model belongs to the field of PCB processing technology, and in particular relates to a double-layer glass inspection mechanism for an AI visual inspection machine. Background Technology

[0002] PCB, also known as printed circuit board, is a provider of electrical connections for electronic components. The design of PCB mainly involves layout design. The main advantages of using PCB are that it greatly reduces wiring and assembly errors, improves automation and production efficiency. During PCB production inspection, testing equipment is usually needed to visually inspect the circuit lines or solder joints of the PCB to ensure that it can be produced in good condition.

[0003] Currently, the circuitry on high-end PCBs and packaging substrates is becoming increasingly fine (down to 8µm). Visual inspection (AOI) of the etched circuitry typically uses single-sided black-and-white AOI (primarily by companies like KLA, Contec, and Giagavis). The workflow is: AOI scanning inspection – defect points are transmitted to the VRS inspection station for image capture, and then manually assessed. This process has the following drawbacks: 1. Only one side of the PCB can be inspected at a time, resulting in low inspection efficiency; 2. The PCB cannot be flattened. If the PCB is severely warped or bent, the imaging effect will be poor, affecting inspection accuracy. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In one embodiment of this utility model, such as Figures 1-4 As shown, a double-layer glass inspection mechanism for an AI visual inspection machine includes a frame 1, a glass inspection platform 2, a glass cover plate 3, and a glass cover moving mechanism 4. The glass inspection platform 2 is fixedly connected to the frame 1, and the glass cover plate 3 is fixedly connected to the glass cover moving mechanism 4, and moves horizontally or vertically via the glass cover moving mechanism 4. The glass cover moving mechanism 4 is connected to the frame 1, and the glass inspection platform 2 is positioned below the glass cover plate 3, forming an inspection channel 5 with the glass cover plate. A PCB board is placed within the inspection channel 5 for imaging inspection.

[0030] The glass cover moving mechanism 4 includes a horizontal moving component 41 and a lifting component 42. The horizontal moving component 41 is connected to the frame 1, and the lifting component 42 is connected to the horizontal moving component 41. The glass cover plate 3 is connected to the lifting component 42. The lifting component 42 moves horizontally through the horizontal moving component 41, thereby driving the glass cover plate 3 to move horizontally. The glass cover plate 3 moves up and down through the lifting component 42, adjusting the height of the detection channel 5. The double-layer glass inspection mechanism of the AI ​​visual inspection machine provided in this application, through the double-layer glass structure of the glass inspection platform 2 and the glass cover plate 3, allows the PCB board to be inspected to be placed between the double-layer glass structure, simultaneously inspecting both sides of the PCB to improve inspection efficiency. The glass cover moving mechanism 4 drives the glass cover plate 3 to move downward, reducing the distance between the glass cover plate 3 and the glass inspection platform 2, and flattening and leveling the PCB on the glass inspection platform 2, preventing the PCB board from warping or bending, thereby improving imaging effect and inspection accuracy.

[0031] In another embodiment of this utility model, the glass inspection platform 2 is disposed below the glass cover plate 3 and is fixedly connected to the frame 1.

[0032] In another embodiment of this utility model, the horizontal moving assembly 41 includes a glass fixing base 411, a glass moving slide rail 412, a glass moving slider 413, a glass moving guide post 414, a glass moving guide block 415, and a glass moving frame 416. The glass moving slide rail 412 is fixedly connected to the glass fixing base, the glass moving slider 413 is slidably connected to the glass moving slide rail 412, the glass moving guide post 414 is fixedly connected to the glass fixing base 411, the glass moving guide block 415 is slidably connected to the glass moving guide post 414, and the glass moving frame 416 is fixedly connected to the glass moving slider 413 and the glass moving guide post 414 respectively. When it is necessary to move the glass moving frame 416, an external force is applied to the glass moving frame 416. Since the glass moving frame 416 is fixedly connected to the glass moving slider 413 and the glass moving guide block 415 respectively, the glass moving slider 413 will slide on the glass moving slide rail 412, and the glass moving guide block 415 will slide on the glass moving guide post 414. These two sliding actions work together to enable the glass moving frame 416 to move smoothly in the horizontal direction, thus realizing the function of the horizontal moving component 41 and driving the lifting component 42 to move horizontally along the slide rail. During the movement, the glass moving slide rail 412 and the glass moving guide post 414 guide and limit the glass moving slider 413 and the glass moving guide block 415 respectively, ensuring that the movement direction of the glass moving frame 416 is accurate and stable.

[0033] In another embodiment of this utility model, the lifting assembly 42 includes a glass lifting cylinder 421, a glass carrier plate 422, a glass lifting slide rail 423, a glass lifting slider 424, and a glass support plate 425. The glass lifting cylinder 421 is fixedly connected to the glass moving frame 416. The glass carrier plate 422 is fixedly connected to the glass lifting cylinder 421 and the glass support plate 425 respectively. The glass top cover plate 3 is fixedly connected to the glass carrier plate 422. The glass lifting slide rail 423 is fixedly connected to the glass moving frame 416. The glass lifting slider 424 is slidably connected to the glass lifting slide rail 423. The glass support plate 425 is fixedly connected to the glass lifting slider 424 and the glass carrier plate 422 respectively.

[0034] Lifting assembly 42 rising process:

[0035] When the glass cover plate 3 needs to be raised, the piston rod of the glass lifting cylinder 421 extends. Since the glass carrier plate 422 is fixedly connected to the piston rod of the glass lifting cylinder 421, the extension of the piston rod pushes the glass carrier plate 422 to move upward.

[0036] The glass carrier plate 422 is fixedly connected to the glass support plate 425, and the glass support plate 425 is fixedly connected to the glass lifting slider 424. Therefore, when the glass carrier plate 422 rises, it drives the glass support plate 425 to rise synchronously.

[0037] Driven by the glass support plate 425, the glass lifting slider 424 slides upward along the glass lifting rail 423 fixed on the glass moving frame 416. The glass lifting rail 423 provides a precise movement trajectory for the glass lifting slider 424, ensuring the smoothness of the rising process of the glass carrier plate 422 and the glass cover plate 3.

[0038] The descent process of lifting component 42:

[0039] When it is necessary to lower the glass cover plate 3, the piston rod of the glass lifting cylinder 421 retracts, pulling the glass carrier plate 422 downward.

[0040] The glass carrier plate 422 drives the glass support plate 425 to descend together, and the glass support plate 425 in turn drives the glass lifting slider 424 to slide down along the glass lifting rail 423.

[0041] The glass carrier plate 422 and the glass cover plate 3 stop descending when the piston rod of the glass lifting cylinder 421 retracts to the appropriate position, completing one descent action.

[0042] In another embodiment of the present invention, the glass lifting slide rail 423 is disposed on one side of the glass lifting cylinder 421 and is disposed parallel to the glass lifting cylinder 421. The length of the glass lifting slide rail 423 is greater than that of the glass lifting cylinder 421 to ensure the lifting stroke.

[0043] In another embodiment of the present invention, the glass support plate 425 is L-shaped, with one end fixedly connected to the glass lifting slider 424 and the other end fixedly connected to the glass carrier plate 422.

[0044] In another embodiment of this utility model, two glass cover moving mechanisms 4 are provided and arranged in parallel opposite directions. Both glass cover moving mechanisms 4 are fixedly connected to the frame 1, and the glass cover plate 3 is fixedly connected to the two glass cover moving mechanisms 4 respectively. By providing two glass cover moving mechanisms 4, the stability of the movement of the glass cover plate 3 is improved.

[0045] The double-layer glass inspection mechanism of the AI ​​visual inspection machine provided in this application, through the double-layer glass structure of glass inspection platform 2 and glass cover plate 3, allows the PCB board to be inspected to be placed between the double-layer glass structure, and simultaneously inspects both sides of the PCB to improve inspection efficiency. The glass cover moving mechanism 4 drives the glass cover plate 3 to move down, reducing the distance between the glass cover plate 3 and the glass inspection platform 2, and flattens and straightens the PCB on the glass inspection platform 2, preventing the PCB board from warping or bending, thereby improving imaging effect and inspection accuracy.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
