Example

[0026] Please see Figure 1-7 A PCBA circuit board testing device includes a fixed frame 1 and lamps 2 fixedly installed on the front and rear sides of the inner cavity of the fixed frame 1. Two L-shaped support legs 3 are fixedly installed on the left and right sides of the fixed frame 1, and the L-shaped support legs 3 are arranged front and rear. Openings are opened on the left and right sides of the bottom of the fixed frame 1. Drive motors 4 are respectively installed in the inner cavity of the openings. U-shaped plates 5 are fixedly installed at the output ends of the drive motors 4. Fixing components 6 are respectively installed in the inner cavity of the U-shaped plates 5 near the front and rear sides. Adjustment components 7 are installed at the bottom of the fixed frame 1. The circuit board can be pressed and positioned by the setting of the fixing components 6, and the spacing of the U-shaped plates 5 can be adjusted by the setting of the adjustment components 7.

[0027] In this embodiment, the fixing component 6 includes a pressure plate 61 disposed in the inner cavity of the right U-shaped plate 5 near the front side and a threaded rod 62 fixedly installed in the middle of the top of the pressure plate 61. A circular opening is provided at the top of the right U-shaped plate 5 near the front side, and the upper end of the threaded rod 62 passes through the circular opening and extends to the outside of the U-shaped plate 5. A threaded sleeve 63 is threadedly installed above the outside of the threaded rod 62, and an L-shaped plate 64 is fixedly installed at the top of the right U-shaped plate 5 near the front side. The upper end of the threaded sleeve 63 extends movably through to the outside of the L-shaped plate 64, which can drive the pressure plate 61 to move downward, thereby pressing and positioning the circuit board.

[0028] Specifically, a limiting telescopic rod 611 is fixedly installed on the top of the pressure plate 61 near the front and rear sides, and the upper end of the limiting telescopic rod 611 is fixedly installed on the inner wall of the U-shaped plate 5. A soft pad 612 is fixedly installed at the middle of the bottom of the pressure plate 61, which serves to limit the movement of the pressure plate 61 and also protect the circuit board.

[0029] Specifically, a knob 631 is fixedly installed at the upper end of the threaded sleeve 63, which can drive the threaded sleeve 63 to rotate.

[0030] In this embodiment: During use, the circuit board can be placed in the inner cavity of the two U-shaped plates 5, and then the knob 631 is rotated to drive the adjacent threaded sleeve 63 to rotate. When the threaded sleeve 63 rotates, it will drive the adjacent threaded rod 62 to move downward. When the threaded rod 62 moves downward, it will drive the adjacent pressure plate 61 to move downward, thereby pressing and positioning the circuit board. After positioning is completed, it can be tested. After the top surface is tested, the drive motors 4 on both sides can be started. When the drive motors 4 run, they will drive the adjacent U-shaped plates 5 to flip, thereby flipping the circuit board and making it easier for the staff to test the bottom surface. Example

[0031] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 5 The adjustment component 7 includes a fixed plate 71 located below the bottom of the fixed frame 1 and a servo motor 72 located below the middle of the bottom of the fixed plate 71. The left and right sides of the fixed plate 71 are respectively fixedly mounted on adjacent L-shaped support legs 3. A rotating rod is fixedly mounted on the output end of the servo motor 72. The upper end of the rotating rod extends movably through to the outside of the fixed plate 71. A movable gear 73 is fixedly sleeved on the output shaft of the rotating rod. A rack plate A74 and a rack plate B75 are respectively meshed on the front and rear sides of the movable gear 73. A sliding plate 76 is fixedly mounted on the opposite side of the rack plate A74 and the rack plate B75, which can drive the U-shaped plates 5 on both sides to move relative to or in opposite directions, thereby clamping and fixing circuit boards of different widths.

[0032] Specifically, hydraulic cylinders 77 are fixedly installed at the middle of the top of the sliding plate 76, and movable seats 78 are fixedly installed at the power end of the hydraulic cylinders 77. The bottom of the drive motor 4 is fixedly installed on the adjacent movable seats 78. The height of the U-shaped plate 5 can be adjusted according to the needs of implementation, which is conducive to the staff to place and pick up the circuit board.

[0033] Specifically, a support frame 721 is fixedly installed at the bottom of the servo motor 72, and the top of the support frame 721 is fixedly installed on the fixed plate 71, which serves to support the servo motor 72.

[0034] Specifically, a sliding block is fixedly installed at the middle of the bottom of the sliding plate 76, and the bottom of the sliding block is slidably installed on the fixed plate 71, which serves to guide and limit the movement of the sliding plate 76.

[0035] In this embodiment: when positioning the circuit board, the height of the U-shaped plate 5 can be adjusted by starting the hydraulic cylinder 77, so that it moves to the outside of the fixed frame 1, which is convenient for the operator. In addition, the spacing between the U-shaped plates 5 can be adjusted as needed. The operation of the servo motor 72 can drive the rotating rod to rotate. When the rotating rod rotates, it will drive the movable gear 73 to rotate. When the movable gear 73 rotates, it will drive the rack plate A74 and rack plate B75 to move relative to each other, which will drive the adjacent sliding plate 76 to move relative to each other. Thus, the hydraulic cylinder 77 and the moving seat 78 can drive the U-shaped plates 5 on both sides to move relative to each other, which can meet the fixed positioning of circuit boards of different widths.

[0036] Working principle: In use, the circuit board can be placed in the inner cavity of the two U-shaped plates 5. Then, the knob 631 is rotated to drive the adjacent threaded sleeve 63 to rotate. When the threaded sleeve 63 rotates, it will drive the adjacent threaded rod 62 to move downward. When the threaded rod 62 moves downward, it will drive the adjacent pressure plate 61 to move downward, thereby pressing and positioning the circuit board. After positioning, it can be inspected. After the top surface is inspected, the drive motors 4 on both sides can be started. When the drive motors 4 run, they will drive the adjacent U-shaped plates 5 to flip, thereby flipping the circuit board over, which is convenient for the staff to inspect the bottom surface. In addition, when inspecting the circuit board... During positioning, the height of the U-shaped plate 5 can be adjusted by starting the hydraulic cylinder 77, moving it to the outside of the fixed frame 1, which is convenient for the operator. In addition, the spacing between the U-shaped plates 5 can be adjusted as needed. The operation of the servo motor 72 can drive the rotating rod to rotate. When the rotating rod rotates, it will drive the movable gear 73 to rotate. When the movable gear 73 rotates, it will drive the rack plate A74 and rack plate B75 to move relative to each other, which will drive the adjacent sliding plate 76 to move relative to each other. Thus, the hydraulic cylinder 77 and the moving seat 78 can drive the U-shaped plates 5 on both sides to move relative to each other, which can meet the fixed positioning of circuit boards of different widths.
