[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: an adjustable circuit board automatic detection platform, including a detection table 2 fixed on a substrate 1 by a column, a strip positioning block 3 is movably provided on the detection table 2, support columns 4 are provided at both ends of the strip positioning block 3, and a visual detection mechanism 5 is provided on the side where the support columns 4 are close to each other. The circuit board is detected by using the visual detection mechanism 5, and clamping mechanisms 8 are provided on both sides of the strip positioning block 3. The side of the support column 4 is connected to a support assembly, and the support assembly includes a connecting arm 7, and a servo-driven flip arm 9 is installed at one end of the connecting arm 7 away from the support column 4;

At this time, the bar positioning blocks are exposed on both sides of the circuit board. The circuit board is clamped by the clamping mechanism 8, and the flipping arm 9 is driven to make the flipping arm 9 and the connecting arm 7 vertical, so that the circuit board is horizontally flipped to a vertical state, and the front and back sides of the circuit board are inspected by the visual inspection mechanism 5 at the same time. Compared with the existing technology, not only can the front and back sides of the circuit board be inspected, but also the double-sided inspection can be completed directly at the same time, so as to achieve a sufficient and thorough inspection effect and effectively improve the inspection efficiency.

[0022] The flip arm 9 is connected to the clamping mechanism 8 via an electric push rod 11;

[0023] Furthermore, the clamping mechanism 8 includes a sleeve plate 81 connected to the stroke end of the electric push rod 11, and the sleeve plate 81 is connected to the stroke end of the electric push rod 11 through fasteners. By controlling the length of the electric push rod 11, the clamping mechanism 8 can be adapted to circuit boards of different widths. A clamping plate 82 is inserted in the sleeve plate 81, and a screw 83 that passes through the sleeve plate 81 is movably installed on the top of the clamping plate 82, and a screw hole connected to the screw 83 is opened on the top of the sleeve plate 81. A movable seat is fixed on the top of the clamping plate 82, and the bottom end of the screw 83 is connected to the movable seat. The screw 83 is locked with the sleeve plate 81 through a nut 84; by rotating the screw 83, the screw 83 is moved up and down in the sleeve plate 81, and then the distance between the clamping plate 82 and the inner wall of the sleeve plate 81 is adjusted to adapt to circuit boards of different thicknesses.

[0024] Further, a motor 10 connected to the flip arm 9 is installed at the end of the connecting arm 7, and the flip arm 9 is connected to the connecting arm 7 through a driving shaft 1, and the driving shaft 1 is fixed to the flip arm 9, and the motor 10 is connected to the driving shaft 1, thereby providing power to the driving shaft 1 to rotate it ninety degrees. The motor 10 is a stepping motor so as to control its output angle. A distance sensor 2 19 is installed on the flip arm 9. The distance sensor 2 19 is opposite to the edge of the circuit board and indirectly obtains the distance between the clamping mechanism 8 and the circuit board so as to extend the electric push rod 11 by a corresponding distance for easy regulation.

[0025] Specifically, by arranging an electric push rod 11 between the flip arm 9 and the clamping mechanism 8 and adjusting the length of the electric push rod 11, the clamping mechanism 8 can adapt to circuit boards of different widths so as to clamp circuit boards of different widths, making the use more flexible and expanding the scope of application.

[0027] Furthermore, a moving opening 12 adapted to the strip positioning block 3 is provided on the inspection table 2, and a cylinder 13 connected to the strip positioning block 3 is installed on the substrate 1; by controlling the length of the piston rod of the cylinder 13, the strip positioning block 3 is moved upward or downward to avoid affecting the flipping of the circuit board.

[0028] Furthermore, a distance sensor 14 opposite to the substrate 1 is installed at the bottom of the bar-shaped positioning block 3; the distance sensor 14 is used to detect the distance between the bar-shaped positioning block 3 and the substrate 1, thereby controlling the movement amplitude of the cylinder 13.
