Push rods 27 are movably connected to the support plate 6. Push rods 27 extend through the support plate 6 to the outside and connect with the pressure plate 28. Threaded sleeves 14 are symmetrically installed at the bottom of one side wall of the U-shaped frame 3.

[0029] When using the circuit board component fixing fixture, the stepper motor 12 is turned on. Supported by the rotating disk 2, the stepper motor 12 drives the threaded rod 13 to rotate. With the threaded connection between the threaded rod 13 and the threaded sleeve 14, and limited by the limit sleeve 15 and the limit rod 16, the threaded rod 13 drives the threaded sleeve 14 to move. The threaded sleeve 14 drives the U-shaped frame 3, the support frame 4, the rotating disk 5, the support disk 6, and the pressure plate 28 to move to a certain height. Then, multiple sets of cylinders 26 are turned on. Supported by the rotating disk 5, the cylinders 26 drive... The push rod 27 moves, which drives the pressure plate 28 to move, causing the pressure plate 28 to disengage from the support plate 6. The circuit board component is placed between multiple pressure plates 28. The cylinder 26 is operated in the opposite direction. With the support of the support plate 6, the pressure plate 28 presses against the circuit board component, which facilitates the clamping of circuit board components of different thicknesses and the convenient adjustment of the height for clamping.

[0032] When multiple circuit board components need to be clamped simultaneously, the servo motor 7 is turned on. Supported by the frame 1, the servo motor 7 drives the worm gear 8 to rotate. Under the meshing of the worm gear 8 and the worm wheel 10, the worm gear 8 drives the worm wheel 10 to rotate. The worm wheel 10 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the rotating disk 2, U-shaped frame 3, support frame 4, rotating disk 5, support disk 6, and pressure plate 28 to rotate.

Supported by the connecting plate 21, the variable frequency motor 22 drives the second synchronous pulley assembly 23 to rotate. The second synchronous pulley assembly 23 drives the support shaft 24 to rotate. The U-shaped frame 3 provides movable support for the support shaft 24 and the auxiliary shaft 25. With the support of the auxiliary shaft 25 on the support frame 4, the support shaft 24 drives the support frame 4, rotating disk 5, support disk 6, pressure plate 28, L-shaped plate 17, power motor 18, first synchronous pulley assembly 19, and rotating shaft 20 to rotate, causing the circuit board component to rotate... At a fixed angle, when the circuit board component needs to rotate, the power motor 18 is turned on. Supported by the L-shaped plate 17, the power motor 18 drives the first synchronous pulley assembly 19 to rotate. The first synchronous pulley assembly 19 drives the rotating shaft 20 to rotate. The rotating shaft 20 drives the rotating disk 5, support disk 6, and pressure plate 28 to rotate circumferentially around the rotating shaft 20.

[0037] Working principle: When using the circuit board component fixing fixture, the stepper motor 12 drives the threaded rod 13 to rotate. The threaded rod 13 drives the threaded sleeve 14 to move. The threaded sleeve 14 drives the U-shaped frame 3, support frame 4, rotating disk 5, support disk 6, and pressure plate 28 to a certain height. Multiple sets of cylinders 26 are then activated. Supported by the rotating disk 5, the cylinders 26 drive the push rod 27 to move. The push rod 27 drives the pressure plate 28 to move, causing the pressure plate 28 to disengage from the support disk 6, placing the circuit board component between the multiple sets of pressure plates 28. The operating cylinder 26, supported by the support plate 6, causes the pressure plate 28 to press against the circuit board component, facilitating the clamping of circuit board components of different thicknesses and allowing for convenient height adjustment during clamping. When multiple circuit board components need to be clamped simultaneously, the servo motor 7 drives the worm gear 8 to rotate, which in turn drives the worm wheel 10 to rotate. The worm wheel 10 then drives the rotating shaft 9 to rotate, which in turn drives the rotating disk 2, U-shaped frame 3, support frame 4, rotating disk 5, support plate 6, and pressure plate 28 to rotate, thus completing the clamping process. One group moves to the processing area, the next group moves to the clamping area, and so on, facilitating sequential clamping. The variable frequency motor 22 drives the second synchronous pulley assembly 23 to rotate, which in turn drives the support shaft 24 to rotate. The U-shaped frame 3 provides movable support for the support shaft 24 and the auxiliary shaft 25. With the support of the auxiliary shaft 25, the support shaft 24 drives the support frame 4, the rotating disk 5, the support disk 6, the pressure plate 28, the L-shaped plate 17, the power motor 18, and the first synchronous... The pulley assembly 19 and the rotating shaft 20 rotate, causing the circuit board component to rotate at a certain angle. When the circuit board component needs to rotate, the power motor 18 is turned on. With the support of the L-shaped plate 17, the power motor 18 drives the first synchronous pulley assembly 19 to rotate. The first synchronous pulley assembly 19 drives the rotating shaft 20 to rotate. The rotating shaft 20 drives the rotating disk 5, the support disk 6, and the pressure plate 28 to rotate circumferentially around the rotating shaft 20, which facilitates convenient adjustment of the angle position and completes the use of the circuit board component fixing fixture.
