[0029] In this application, the locking mechanism 400 and the conveying mechanism 300 are provided in two sets. One conveying mechanism 300 conveys the workpiece to one locking mechanism 400, and the other conveying mechanism 300 conveys the workpiece on the other locking mechanism 400 to the feeding line 200 so that it flows to the next process.

[0030] In other words, in use, this application uses one station for feeding and processing, and another station for returning materials to be fed, so as to achieve continuous production without stopping the machine and improve production efficiency.

[0031] The conveying mechanism 300 includes a conveying unit 301 and a moving module 302. The conveying unit 301 is connected to the moving module 302, which drives it to move linearly. The moving module 302 is a linear module and is configured to drive the conveying unit 301 to move linearly, thereby conveying the workpiece on the feeding line 200 to any of the locking mechanisms 400.

[0032] The locking mechanism 400 includes a screw-locking unit 401, a screw-supplying unit 402, and a flip-fixing unit 403 for adjusting and fixing the workpiece angle. The flip-fixing unit 403 includes a rotating table 404, a first driving member 405, a pressing fixing member 406, a driving assembly 407, a mounting bracket 408, and a second driving member 409.

[0033] The second drive unit 409 can be a linear module. The second drive unit 409 is configured to drive the mounting bracket 408 to move. The moving direction of the mounting bracket 408 is perpendicular to the moving direction of the conveying unit 301, and the running direction of the feeding line 200 is perpendicular to the moving direction of the conveying unit 301.

[0034] In one embodiment, at the material handling station, one of the conveying units 301 removes the workpiece from the rotating table 404, and another conveying unit 301 places the workpiece on the rotating table 404; at the screw fastening station, the screw fastening unit 401 fastens screws on the workpiece, and the second driving component 409 drives the mounting bracket 408 to move to realize the switching of the station and the fine adjustment of the position.

The connecting part 411 is fixedly connected to the rotating shaft, and the rotating shaft is connected to the rotating table 404 through a bearing. The connecting part 411 is perpendicular to the pressing part 410. The pressing part 410 rotates and contacts the workpiece, pressing the workpiece to prevent the workpiece from shifting when the rotating table 404 rotates.

[0037] The driving assembly 407 includes a linear pusher 412 and a connecting assembly 413. The connecting assembly 413 includes a linkage mechanism 414 and a connector 415 assembled at the end of the pressing and fixing member 406.

The linkage mechanism 414 includes a moving plate 416, a connecting rod 417, and a connecting transmission member 418. The moving plate 416 is drivenly connected to the linear pusher 412. Two inclined slots 419 are formed on the moving plate 416. The connecting rod 417 is disposed in the two inclined slots 419 and slides with them. The connecting rod 417 is fixedly connected to the connecting transmission member 418, and the connecting transmission member 418 is rotatably connected to the connector 415.

[0038] The linear actuator 412 is preferably a cylinder, which is fixedly mounted on the rotating table 404. The linear actuator 412 drives the connecting member 415 to rotate via the linkage mechanism 414, and the connecting member 415 drives the pressing and fixing member 406 to rotate. The piston rod of the cylinder is fixedly connected to the moving plate 416, and the moving plate 416 is connected to the rotating table 404 via a guide rail slider; the cylinder can drive the moving plate 416 to move. The inclined groove 419 is used to convert the movement along the moving plate 416 into vertical movement. The connecting rod 417 drives the connecting transmission member 418 to move, and the connecting transmission member 418 drives the pressing and fixing member 406 to rotate via the connecting member 415.

[0039] The connecting member 415 is a gear, and the connecting transmission member 418 is a rack; the pressing and fixing member 406 fixes the workpiece, and the connecting transmission member 418 drives the pressing and fixing member 406 to rotate through the connecting member 415, thereby realizing the screwing of the side of the workpiece.

[0040] The screw fastening unit 401 includes a screw fastening machine 420, a connecting plate 421, a dual-axis moving module 422, and an adjusting component 423. The dual-axis moving module 422 is drivenly connected to the connecting plate 421, and the screw fastening machine 420 is slidably connected to the connecting plate 421. The dual-axis moving module 422 described in this application is a mature existing design, used to drive the screw fastening machine 420 to move horizontally at different workstations and vertically to fasten screws downwards. The dual-axis moving module 422 is a mature existing technology and will not be described further.

[0041] The adjusting assembly 423 includes a liftable movable rod 424, a connecting fastener 425, and an elastic element 426. The movable rod 424 and the connecting fastener 425 are connected in a traction linkage. The elastic element 426 is sleeved on the movable rod 424, and the connecting fastener 425 is fixedly connected to the screw fastening machine 420. The upper end of the movable rod 424 is a threaded rod, and the upper end of the movable rod 424 is connected to a drive motor 427. When the drive motor 427 rotates, it causes the movable rod 424 to rise or fall. The lower end of the movable rod 424 is a cut-off end, which allows the movable rod 424 to drive the connecting fastener 425 to move upward through the cut-off end. The elastic element 426 is preferably a spring, which plays a role in buffering and shock absorption.

[0042] When the dual-axis moving module 422 drives the screw fastening machine 420 to move downward and contact the workpiece, the screw fastening machine 420 can move upward, and the elastic element 426 will buffer and reduce shock.

[0043] This application uses a floating screw fastening machine 420, which can effectively reduce vibration and prevent damage to the workpiece.

[0044] The screw feeding unit 402 includes a screw feeder 428 and a drive mechanism 429 that drives the screw feeder 428 to move linearly. The drive mechanism 429 is preferably a linear module, meaning the screw feeder 428 is mounted on a mounting plate of the linear module. The drive mechanism 429 drives the screw feeder 428 to move, facilitating screw removal. The screw feeder 428 uses a readily available and mature design, which will not be described in detail here.

[0045] In one embodiment, the screw feeder 428 is connected to a feed channel 430, which is fixedly installed on a protective frame, thereby allowing screws to be added into the screw feeder 428.

[0046] The handling unit 301 includes a material picking module 303 and a gripper cylinder 304 mounted on the material picking module 303. The material picking module 303 is used to drive the gripper cylinder 304 to move vertically, and the gripper cylinder 304 is used to pick up materials.
