[0043] See also Figure 3 and Figure 4 The screw locking assembly 3 further includes a limiting mechanism 35. The limiting mechanism 35 is mounted on one end of the second mounting member 331 close to the part to be locked 5. The limiting mechanism 35 is located on a side of the air chamber 338 close to the part to be locked 5 and is used to control the lowest point of the air chamber 338 sliding toward the part to be locked 5.

[0044] When the automatic screw tightening device of the present application is in use, the screw vibrating plate 311 delivers the screws one by one in an orderly manner through the screw supply pipe 312 and the screw supply connector 313 to the clamping flap 321 of the screw clamp mechanism 32. The clamping flap cylinder 322 controls the clamping flap 321 to close, thereby tightening the screws. The second cylinder 337 drives the third mounting member 335 and the second slider 334 to move downward toward the part to be tightened 5. The third mounting member 335, via the connecting rod 3310 and the suction elastic member 3314, pushes the air chamber 338 and the first slider 333 downward toward the part to be tightened 5. As the air chamber 338 moves downward toward the part to be tightened 5, it pushes the screw suction tube 339 downward toward the part to be tightened 5 via the first sealing member 3311, the second sealing member 3312, and the suction elastic member 3313 to suck the screws from the clamping flap 321. The clamping flap cylinder 322 controls the clamping flap 321 to open, thereby loosening the screws. The first cylinder 336 drives the second cylinder 337 to move downward toward the component 5 to be locked. The second cylinder 337 drives the third mounting member 335 to compress the elastic member 3314 downward to drive the electric screwdriver 341 on the third mounting member 335 to move downward toward the component 5 to be locked. The electric screwdriver 341 drives the screw bit 342 to move downward toward the component 5 to be locked to screw the screw into the screw hole of the component 5 to be locked. It is worth noting that in this embodiment, the second cylinder 337 is operated first to drive the screw suction tube 339 to suck the screw, and then the first cylinder 336 is operated to drive the electric screwdriver 341 and the screw bit 342 to screw the screw. In other embodiments, the first cylinder 336 can also be operated first to drive the screw suction tube 339 to suck the screw, and then the second cylinder 337 can be operated to drive the electric screwdriver 341 and the screw bit 342 to screw the screw.

[0045] The screw suction tube 339 of the automatic screw locking device of the present application adopts a vacuum suction method to suck the screws and cooperates with the screw locking mechanism 34, which can improve the stability of screw suction and locking. Compared with the traditional manual screw locking process, it can greatly improve the screw locking efficiency and screw locking yield.

[0046] The screw suction tube 339 of the present application is telescopically connected to the first sealing member 3311 at one end away from the part to be locked 5 through the suction elastic part 3313. Therefore, when the surface of the head of the screw at the clamping flap 321 close to the side of the part to be locked 5 is not attached to the surface of the clamping flap 321 away from the side of the part to be locked 5, the screw suction tube 339 can move upward by compressing the suction elastic part 3313 to adapt to the position of the screw, that is, the suction elastic part 3313 can be used to enable the screw suction tube 339 to adapt to the height difference of the head of the screw at the clamping flap 321.

[0047] See also Figure 7 and Figure 8The screw height detection assembly 4 is mounted on the displacement assembly 2 and is used to detect the height of the screw after tightening.

Specifically, the detection rail 44 is fixedly mounted on the side of the first connecting member 43 away from the detection cylinder 41, the detection slider 45 is slidably mounted on the detection rail 44, the second connecting member 46 is fixedly mounted on the detection slider 45 and is used to fix the detection slider 45 and the height detector 42, the third connecting member 47 is fixedly mounted on one end of the first connecting member 43 in the first direction M away from the to-be-locked member 5, and the detection elastic member 48 is fixedly connected to the second connecting member 46 and the third connecting member 47 at both ends in the first direction.

[0051] The fourth connecting member 49 extends along the second direction N and is mounted on the second connecting member 46 . Specifically, the fourth connecting member 49 is fixedly mounted on the second connecting member 46 .

[0052] See also Figure 7 and Figure 8 The height detector 42 can be slidably mounted on the first connecting member 43 . The height detector 42 includes a detection body 421 , a detection probe 422 , a detection sensor 423 , a detection elastic portion 424 and a detection reference block 425 .

[0053] The detection body 421 is mounted on the second connecting member 46, the detection sensor 423 is mounted on one end of the detection body 421 in the first direction N, the detection elastic portion 424 extends along the first direction M, and the two ends of the detection elastic portion 424 are respectively fixedly connected to the detection body 421 and the detection probe 422, so that the detection probe 422 can be telescopically mounted on the end of the detection body 421 away from the detection sensor 423. The detection reference block 425 is arranged around the outer periphery of the detection body 421 and mounted on the second connecting member 46.

[0054] After the screw is locked and enters the part to be locked 5, the automatic screw locking device of the present application drives the detection cylinder 41, the height detector 42, the first connecting part 43, the detection slide rail 44, the detection slider 45, the second connecting part 46, the third connecting part 47, the detection elastic part 48, the fourth connecting part 49 and the fifth connecting part 410 to move as a whole in the first direction M through the displacement component 2; then the first connecting part 43 and the height detector 42 slidably mounted on the first connecting part 43 are driven to move in the first direction M by the detection cylinder 41, so as to fit the detection probe 422 to the top surface of the head of the locked screw, and fit the detection reference block 425 to the part to be locked 5 on the periphery of the locked screw, thereby measuring the height of the locked screw, monitoring the locking yield of the screw, and improving the reliability of the screw locking.

[0055] The height detector 42 of the present application is slidably connected to the first connecting member 43 through the detection elastic member 48, the detection slider 45, and the detection slide rail 44. Therefore, when there is a height difference between the part to be locked 5 and the first connecting member 43 in the first direction M, the part to be locked 5 pushes the detection reference block 425 to move upward, and then the detection reference block 425 drives the fourth connecting member 49 and the second connecting member 46 to move upward to compress the detection elastic member 48. Then, the height detector 42 can adapt to the different heights of the parts to be locked 5 by compressing the detection elastic member 48.
