[0002] Real-time circuit board inspection systems are widely used in production lines, repair centers, and research laboratories for various electronic products, enabling real-time inspection of circuit boards. These systems often utilize automated optical inspection machines, an automatic inspection technology based on optical principles, primarily used for inspecting electronic components, printed circuit boards (PCBs), and other optical assemblies. High-definition cameras automatically scan the object to be inspected, acquiring images, which are then analyzed and processed using computer algorithms to achieve fast and high-precision inspection. While real-time circuit board inspection systems detect defective circuit boards, the difficulty of removing them from the conveyor belt presents certain drawbacks. Therefore, we propose a new real-time circuit board inspection system. Utility Model Content

[0004] Therefore, the technical solution adopted by this utility model is as follows: a real-time circuit board inspection system, including an automatic optical inspection machine, a screening table, a mounting base, a cylinder, an ejection assembly, and a guide plate. The screening table is arranged on the left side of the automatic optical inspection machine. The mounting base is bolted to the top of the screening table. Scale lines are provided on both sides of the mounting base. The cylinder is arranged on the mounting base. A fixing seat is arranged on the cylinder. First fastening knobs are threaded to both sides of the fixing seat. The ejection assembly is arranged on the rear side of the cylinder. The guide plate is arranged on the top of the screening table.

[0005] Preferably, the mounting base has two mounting holes for fixing, and the two mounting holes are symmetrically distributed.

[0006] Preferably, the fixing seat is inserted through the outside of the mounting base, and the top of the fixing seat is threaded with a second fastening knob.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a real-time circuit board detection system.

[0024] Example 1:

[0025] Reference Figure 1-4 This is the first embodiment of the present invention. This embodiment provides a real-time circuit board inspection system, including an automatic optical inspection machine 100, a screening table 200, a mounting base 300, a cylinder 400, an ejection assembly 500, and a guide plate 600.

[0026] Specifically, the screening table 200 is located on the left side of the automatic optical inspection machine 100. In use, the screening table 200 is used to install the mounting base 300, cylinder 400, ejection assembly 500 and guide plate 600 in order to screen out unqualified circuit boards.

[0027] Specifically, the mounting base 300 is bolted to the top of the screening table 200. Scale lines 301 are provided on both sides of the mounting base 300. Two mounting holes 302 for fixing are provided on the mounting base 300. The two mounting holes 302 are symmetrically distributed. In use, the mounting base 300 can be placed on the screening table 200, and then the bolts are passed through the mounting holes 302 and threadedly connected to the screening table 200 to fix the mounting base 300. After fixing, the height of the cylinder 400 can be adjusted through the mounting base 300, and the distance between the ejector component 500 and the conveyor belt during ejection can be precisely adjusted through the scale lines 301.

[0028] Specifically, the cylinder 400 is mounted on the mounting base 300, and a fixing seat 401 is mounted on the cylinder 400. Both sides of the fixing seat 401 are threaded with first fastening knobs 402. The fixing seat 401 is inserted through the outside of the mounting base 300, and a second fastening knob 403 is threaded to the top of the fixing seat 401. The two second fastening knobs 403 are symmetrically distributed. Both the second fastening knobs 403 and the first fastening knobs 402 are T-shaped studs. A hole 404 for fixing the ejector assembly 500 is provided on the rear side of the cylinder 400, and a disc is provided on the rear side of the cylinder 400. In use, the user can align the fixing seat 401 of the cylinder 400 with the bottom of the mounting base 300 and insert it. After insertion, the mounting base 300 is placed on the screening table 200, and then... After being secured with bolts, the mounting base 401 and cylinder 400 can be moved up and down. When moving, the scale line 301 can be referenced. After moving to the appropriate height, the first fastening knob 402 can be tightened to precisely adjust the distance between the ejector component 500 and the conveyor belt during ejection. This avoids damage to the ejector component 500 due to friction or impact with the conveyor belt. After installation and docking, the cylinder 400 can be extended. The extended cylinder 400 can push the defective circuit board into the guide plate 600 through the ejector component 500, and then slide down through the guide plate 600, making it easy to remove the defective circuit board. At the same time, the second fastening knob 403 can be rotated to hold the first fastening knob 402 against it, preventing the first fastening knob 402 from loosening and causing the cylinder 400 to move downwards, ensuring high stability.

[0029] Specifically, the ejector assembly 500 is located behind the cylinder 400. The ejector assembly 500 includes a round rod 501 inserted into the insertion hole 404, a spring 502 inserted outside the round rod 501 and fixedly connected to the cylinder 400, and a push plate 503 located behind the round rod 501 and the spring 502. The ejector assembly 500 also includes a buffer pad 504 bonded to the back of the push plate 503 and a pressure sensor 505 located behind the push plate 503. During use, the spring 502 provides a certain buffering effect to the push plate 503, which can reduce wear. The buffer pad 504 can also reduce wear, greatly extending the service life of the ejector assembly 500. At the same time, the pressure sensor 505 can sense pressure. When the ejector assembly 500 collides with the conveyor belt, the pressure sensor 505 can sense a large pressure and will feed back to the automatic optical inspection machine 100. The automatic optical inspection machine 100 will control the cylinder 400 to stop extending and retracting, which can prevent the ejector assembly 500 from being damaged by the collision with the conveyor belt.

[0030] Specifically, the guide plate 600 is installed at the top of the screening table 200. In use, the guide plate 600 has a guiding function to guide the unqualified circuit boards to the collection device.

[0031] The working principle and usage process of this utility model are as follows: When in use, the user can align the fixed seat 401 of the cylinder 400 with the bottom of the mounting seat 300 and insert it. After insertion, the mounting seat 300 is placed on the screening table 200 and fixed with bolts. After fixing, the fixed seat 401 and the cylinder 400 can be moved up and down. When moving, the scale line 301 can be referenced. After moving to a suitable height, the first fastening knob 402 is tightened to accurately adjust the distance between the ejection component 500 and the conveyor belt when ejecting, so as to avoid the problem of damage to the ejection component 500 due to friction or impact with the conveyor belt. After installation and docking, the cylinder 400 can be extended. The extended cylinder 400 can push the unqualified circuit board into the guide plate 600 through the ejection component 500, and then slide down through the guide plate 600, so that the unqualified circuit board can be easily removed. At the same time, the spring 502 of the ejection component 500 gives the push plate 503 a certain buffering effect, which can reduce wear. The buffer pad 504 can also reduce wear and extend the service life of the ejection component 500.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
