The positioning component 4 is arranged on the case 1 and is positioned below the batch head for accommodating a workpiece. The power part is arranged on the support frame 2 and is in transmission connection with the screwdriver 31 to drive the screw guide head 33 and the screwdriver head to be close to or far away from a workpiece.
After the feeding assembly (e.g. hopper) feeds the screws into the guide channels of the screw guide head 33 through the feeding pipe 331, the execution instructions are sent to the power section and the plurality of electric batons 31 through the electric control module. The power portion drives the screw guide head 33 toward the workpiece. Then the screwdriver 31 rotates to rotate the screw in the screw guide head 33 to the positioned workpiece through the screwdriver head without manual screwing, so that the automatic locking of the screw on the workpiece is realized, and the effect of improving the working efficiency is achieved. And the screw is not touched by hands, so that the screw is prevented from being polluted.
Preferably, as shown in fig. 1 and fig. 2, the automatic screw locking machine in the present embodiment has 12 locking assemblies 3 in total, and the working efficiency is as high as 120/min.
In particular, referring to fig. 5 together, the lock assembly 3 further comprises a first universal joint 34, a hollow rod 35, a shaft 36, a second universal joint 37, a first spring 38 and a pin 39. One end of the first universal joint 34 is fixedly connected with the rotating shaft 311 of the electric screwdriver 31, and the other end is fixedly connected with the hollow rod 35.

Further, the auto-screwdriving machine further comprises a second spring 9. The second spring 9 is sleeved on the support shaft 22, and two ends of the second spring respectively abut against the first shaft sleeve and the second shaft sleeve. When the cylinder 5 drives the second mounting plate 72 to descend along the supporting shaft 22, the second spring 9 is compressed, and the generated elastic force is increased, so that the second mounting plate 72 and the structure thereon can descend more smoothly, and sudden descent is avoided.
Referring to fig. 7, the positioning assembly 4 includes a linear module 41 and a positioning socket 42. The linear module 41 is arranged on the chassis 1 and electrically connected with the electronic control module. The positioning seat 42 is provided with a containing groove adapted to the shape of the workpiece. The positioning seat 42 is mounted on the linear module 41. The positioning seat 42 is driven by the linear module 41 to move back and forth between the loading position and the processing position, so that the situation that both hands are accidentally injured by the locking component 3 can be completely avoided, and the safety of the screw locking machine is greatly improved. It should be noted that the electric batch 31 and the linear module 41 can be purchased through conventional approaches, and the structure thereof is not described herein in detail.
Still referring to fig. 1, the auto-screwdriving machine further includes an operation panel 10. The operation panel 10 is disposed on the chassis 1 and electrically connected to the electronic control module.
