[0002] The names of circuit boards include: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board and printed circuit board, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Double-sided boards are an extension of single-sided boards. When single-layer wiring cannot meet the needs of electronic products, double-sided boards must be used. There are copper clad and traces on both sides, and the circuits between the two layers can be connected through vias.

This results in the installation process being extremely delicate and fragile, requiring operators to exercise extreme caution to avoid scratches, collisions, and other damage. This focus on protecting the PCB directly slows installation, impacting the efficiency of the entire inspection process, necessitating improvements. Summary of the Invention

[0032] Example, see Figures 1 to 13, is an embodiment of the present invention, which provides a PCB circuit board AOI system that can achieve the rapid installation of various types of PCB circuit boards and the effect of automatic flipping during the subsequent inspection process. It includes a detection component 100, a conveying component 200 fixed inside the detection component 100, a flipping component 300 fixed on the top of the conveying component 200, an expansion component 400 movably connected to the inside of the flipping component 300, four clamping components 500 sliding inside the expansion component 400, an elastic component 600 fixed between the flipping component 300 and the expansion component 400, a ratchet component 700 fixed to the outer wall of the flipping component 300, a trigger component 800 and a reset component 900 fixed to one side of the flipping component 300. When the PCB circuit board is installed, After placing the PCB circuit board on the clamping assembly 500, the limit of the elastic assembly 600 by the ratchet assembly 700 is released, and then the elastic assembly 600 drives the expansion assembly 400 to trigger the clamping assembly 500 to fix the PCB circuit board. The ratchet assembly 700 can adjust the initial position of the clamping assembly 500, which is convenient for placing various types of PCB circuit boards. When the conveying assembly 200 drives the flipping assembly 300 and the clamping assembly 500 to move into the detection assembly 100 for detection, and the conveying assembly 200 continues to drive the subsequent structure to move, it can drive the trigger assembly 800 to trigger the flipping assembly 300 to flip. After the conveying assembly 200 drives the subsequent structure to reset, the reset assembly 900 cooperates with the subsequent structure to drive the PCB circuit board to reset and flip.

The driving end of the motor 204 is connected to the screw 202. The motor 204 can be driven by electricity. When in use, the screw 202 and the moving block 203 are driven to move by starting the motor 204.

[0034] Further, such as Figure 4 In the figure, the flip assembly 300 includes a concave frame 301 fixed on the conveying assembly 200, a mounting shell 302 rotating on the top of the concave frame 301, a movable groove 303 is provided inside the mounting shell 302, and the movable groove 303 on the inner wall of the mounting shell 302 has four openings.

The four trapezoidal blocks 503 can form a supporting effect for the PCB circuit board and are fixed between the clamping rod 501 and the trapezoidal blocks 503. The No. 1 spring 504 is used by placing the PCB on the four trapezoidal blocks 503. The rotation of the open ring 401 can drive the clamping rod 501 in the inclined groove 404 to move inward. The trapezoidal blocks 503 will stop after contacting the PCB, and the clamping rod 501 will continue to move to squeeze the No. 1 spring 504. The end of the clamping rod 501 will extend from the trapezoid of the trapezoidal block 503, and the PCB will be fixed by the inclined surface of the end of the clamping rod 501.

[0037] Further, such as Figure 9 In the figure, the elastic component 600 includes an arc block 601 fixed at the opening of the open ring 401, a fixed block 602 sliding inside the top of the arc block 601, a No. 2 spring 603 fixed between the arc block 601 and the fixed block 602, and a ratchet groove 604 is provided on the outer wall of the arc block 601.

[0038] Further, such as Figure 10 、 11 In the figure, the ratchet assembly 700 includes a device shell 701 fixed to the outer wall of the mounting shell 302, a pull rod 702 sliding in the center of the device shell 701, a ratchet block 703 is provided at the end of the pull rod 702, and a No. 3 spring 704 is provided between the device shell 701 and the pull rod 702.

[0039] Further, such as Figure 12 、 13In the figure, the trigger assembly 800 includes a fixed base 801 fixed to the side end of the concave frame 301, a tooth plate 802 sliding on the top of the fixed base 801, baffles 803 fixed on both sides of the tooth plate 802, and a gear 804 engaged with the top of the tooth plate 802. The teeth on the tooth plate 802 can drive the gear 804 to rotate half a circle. The inner wall of the gear 804 is connected to the rotating end of the mounting shell 302. The trigger block 805 is fixed to the top of the conveying assembly 200. When in use, the baffle 803 contacts the trigger block 805 to drive the tooth plate 802 to move. The tooth plate 802 can drive the gear 804 to rotate half a circle, and then the baffle 803 contacts the fixed base 801.

[0040] Further, such as Figure 13 In the embodiment, the reset assembly 900 includes a round tube 901 fixed to the side end of the concave frame 301 and a coil spring 902 fixed between the round tube 901 and the mounting shell 302 .

[0041] When in use, when it is necessary to install the PCB circuit board, the pull rod 702 and the ratchet block 703 are disengaged from the ratchet groove 604, so that the arc block 601 and the open ring 401 are released from the restriction. By rotating the open ring 401 and the inclined groove 404, the clamping rod 501 in the inclined groove 404 can drive the trapezoidal block 503 to move inward. After the adjustment is completed, the ratchet assembly 700 is reset, and the placement space of the four trapezoidal blocks 503 can be adjusted to adapt to the corresponding PCB circuit board. After the PCB circuit board is placed on the four trapezoidal blocks 503, the ratchet assembly 700 is released from the arc block 601 and the open ring 401. The limit of the second spring 603 in the elastic component 600 drives the arc block 601 and the open ring 401 to rotate, and the clamping rod 501 in the open ring 401 and the inclined groove 404 will move inward, and the four clamping rods 501 will drive the corresponding trapezoidal blocks 503 to squeeze the PCB circuit board. When the trapezoidal block 503 hits the PCB circuit board and cannot move, the clamping rod 501 continues to move and squeezes the first spring 504. At the same time, the inclined end of the clamping rod 501 will protrude from the trapezoidal part of the trapezoidal block 503, so that the inclined end of the clamping rod 501 will fix the top of the PCB circuit board, thereby completing the rapid fixation of various sizes. inch PCB circuit board, and then the conveying component 200 can drive the flip component 300 and its subsequent structures to move into the detection component 100, so that the detection component 100 can detect the PCB circuit board, and when the conveying component 200 continues to drive the flip component 300 and its subsequent structures to move, the flip component 300 will drive the baffle 803 in the trigger component 800 to contact the trigger block 805, thereby the baffle 803 and the tooth plate 802 will move, and the tooth plate 802 will drive the gear 804 to rotate half a circle, and the rear baffle 803 will contact the fixed seat 801, during this process, the gear 804 will drive the mounting shell 302 The mounting shell 302 and its subsequent structures as well as the PCB circuit board are flipped over. During this process, the mounting shell 302 will trigger the coil spring 902, so that the PCB circuit board can be inspected on the front and back sides in the inspection component 100. When the inspection is completed, the conveying component 200 drives the flipping component 300 and its subsequent structures to reset. The coil spring 902 will drive the mounting shell 302 and its subsequent structures to flip and reset. When the PCB circuit board needs to be disassembled, the limit of the elastic component 600 and the expansion component 400 by the ratchet component 700 is released, so that the reversal of the expansion component 400 can drive the clamping component 500 to release the fixation of the PCB circuit board.

[0042] In summary, through the expansion component 400, the clamping component 500, the elastic component 600, and the ratchet component 700, the PCB circuit board can be safely installed and quickly fixed, as well as disassembled. Through the flip component 300 and the trigger component 800, the PCB circuit board can be safely and quickly installed, and the effect of double-sided detection can be achieved through one installation.
