[0034] The automatic screw fastening device in this embodiment integrates a vacuum suction head 7 for picking up parts to be assembled. Driven by a displacement component and an angle adjustment component 5, the vacuum suction head 7 moves the parts to be assembled onto the workpiece to be screwed. Then, an electric screwdriver 6 aligns with the screw holes of the workpiece to be screwed and performs the screw fastening operation, thereby assembling the parts onto the workpiece. Through this design, the automatic screw fastening device integrates the function of transferring parts to be assembled, effectively improving production efficiency.
[0035] Furthermore, the displacement components in this embodiment include a Y-axis linear module 2, an X-axis linear module 3, and a Z-axis linear module 4;
[0036] The Y-axis linear module 2 is mounted on the frame 1, the X-axis linear module 3 is connected to the Y-axis linear module 2, and the Z-axis linear module 4 is connected to the X-axis linear module 3.

[0038] It should be noted that the above design enables the vacuum suction head 7 and the electric screwdriver 6 to move in the X, Y, and Z axes.
[0039] Furthermore, the angle adjustment component 5 in this embodiment includes a rotary motor and a speed reducer;
[0040] The output end of the rotary motor is connected to the input end of the reducer, and the output end of the reducer is connected to the support base 11. The rotary motor drives the support base 11 to rotate around the Z-axis through the reducer.
[0041] It should be noted that, through the above design, the vacuum nozzle 7 and the electric screwdriver 6 can be rotated around the Z-axis, thereby adjusting the angle of the vacuum nozzle 7 and the electric screwdriver 6, which makes it easier for the vacuum nozzle 7 to accurately pick up and place the parts to be assembled, and for the electric screwdriver 6 to accurately tighten the screws.
[0042] Furthermore, the buffer assembly 8 in this embodiment includes a connecting block 801, a first slider 802, a second slider 804, a first elastic element 807, a second elastic element, a Z-axis slide rail 803, an X-axis slide rail 805, and a fixing block 806.

[0044] It should be noted that, through the above design, during the process of the vacuum suction head 7 moving the part to be assembled to the workpiece, the vacuum suction head 7 will apply a certain pressure to the part to be assembled so that the part to be assembled fits with the workpiece. At this time, the vacuum suction head 7 can move along the X-axis and Z-axis directions and compress the second elastic element and the first elastic element 807, thereby buffering the pressure of the vacuum suction head 7 pressing on the part by the buffer component 8, and preventing the part or workpiece from being crushed.

[0049] The CCD detection component 9 is mounted on the mounting plate 10.
[0050] It should be noted that the CCD detection component 9 in this embodiment is mainly used to detect the position of the screw hole on the workpiece, so that the displacement component and the angle adjustment component 5 can accurately drive the electric screwdriver 6 to move to the position of the screw hole, thereby accurately completing the screw fastening process.
