When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0051] In order to further understand the application content, features and effects of the present application, the following embodiments are exemplified and described in detail with reference to the drawings as follows.

[0052] Please refer to Figure 3 , Figure 3 , which is a three-dimensional view of a screw-twisting device. In this example, the screw-twisting device is used to automatically assemble screws onto cards, and it includes a frame 1, a first feeding mechanism 2, a second feeding mechanism 3, a picking mechanism 4, and a twisting rod mechanism 5. The frame 1 is used to carry the first feeding mechanism 2, the second feeding mechanism 3, the picking mechanism 4, and the twisting rod mechanism 5. The first feeding mechanism 2 is used to feed screws one by one. The second feeding mechanism 3 is used to feed cards one by one to the twisting rod mechanism 5. The picking mechanism 4 is used to pick up screws and transfer them to the twisting rod mechanism 5. The twisting rod mechanism 5 is used to twist the screws onto the cards.

[0053] Among them, the frame 1 is provided with a blanking groove 11. The first feeding mechanism 2 and the second feeding mechanism 3 are both arranged on the frame 1. The picking mechanism 4 is movably arranged on the frame 1. The twisting rod mechanism 5 includes a bearing assembly 51 and a twisting rod assembly 52. The bearing assembly 51 includes a bearing member 511 and a pushing member 512. The bearing member 511 is rotatably arranged on the frame 1 and is provided with a feeding port 5111. The pushing member 512 is arranged on the frame 1. The twisting rod assembly 52 is arranged on the frame 1. The second feeding mechanism 3, the pushing member 512, and the blanking groove 11 are sequentially located on the rotation path of the feeding port 5111.

[0054] Specifically, both the first feeding mechanism 2 and the second feeding mechanism 3 use the jitter feeding method to feed the screws and cards piece by piece with jitter respectively. Both are vibrating trays. The picking mechanism 4 can move on the frame 1 in the horizontal and height directions. The cross-section of the bearing member 511 is circular, and a feeding port 5111 is provided at the periphery of the side facing away from the frame 1. The bearing member 511 can rotate on the frame 1. The pushing member 512 can extend into the feeding port 5111. When the bearing member 511 rotates one week, the feeding port 5111 passes through the second feeding mechanism 3, the pushing member 512 and the discharging chute 11 in sequence. The torsion bar assembly 52 and the pushing member 512 are located on the same side of the bearing member 511, and the pushing member 512 is located above the bearing member 511. When the feeding port 5111 rotates to face the pushing member 512, the torsion bar assembly 52 also faces the feeding port 5111.

[0055] During specific application, the staff puts the screws into the first feeding mechanism 2 and the cards into the second feeding mechanism 3. The picking mechanism 4 picks the separated screws from the first feeding mechanism 2 and installs the screws on the torsion bar assembly 52 of the torsion bar mechanism 5. At the same time, when the feeding port 5111 of the bearing member 511 rotates to face the second feeding mechanism 3, the cards enter the feeding port 5111 from the second feeding mechanism 3. Then the bearing member 511 continues to rotate, and the cards follow the feeding port 5111 to rotate to the torsion bar assembly 52. The pushing member 512 pushes the cards into the feeding port 5111, so that when different cards rotate to the torsion bar assembly 52, the positions of the cards in the feeding port 5111 are kept consistent. The torsion bar assembly 52 drives the screw to move to the screw hole of the card and drives the screw to rotate, so that it is screwed into the screw hole. Then the torsion bar assembly 52 resets, and the screw exits from the torsion bar assembly 52. The bearing member 511 continues to rotate. When the feeding port 5111 moves to the discharging chute 11, the staff unloads the cards with screws installed, or automatically unloads the cards with screws installed through the discharging mechanism.

[0056] In this way, by setting the first feeding mechanism 2 and the second feeding mechanism 3 to feed the screws and cards respectively, the picking mechanism 4 transfers the screws fed by the first feeding mechanism 2 to the torsion bar assembly 52. The feeding port 5111 of the bearing member 511 first rotates to the second feeding mechanism 3 to carry the cards, and then rotates to the pushing member 512. The pushing member 512 pushes the cards into the feeding port 5111 to prevent the cards from moving or being misaligned in the feeding port 5111 during the rotation of the bearing member 511. Then the torsion bar assembly 52 twists the screw onto the card. Finally, the bearing member 511 rotates to the discharging chute 11 to unload the cards with screws twisted, realizing the process of automatically twisting screws onto the cards and improving the assembly efficiency of the fasteners.

[0057] Please refer to Figure 4 , Figure 4FIG. 0 is a schematic structural diagram of the first feeding mechanism. Further, the first feeding mechanism 2 includes a first support 21, a first vibrating tray 22, a connecting pipe 23, and a discharging member 24. The first support 21 and the discharging member 24 are both arranged on the frame 1. The first vibrating tray 22 is arranged on the first support 21. The connecting pipe 23 communicates the first vibrating tray 22 and the discharging member 24.

[0058] Specifically, the first support 21 is used to support the first vibrating tray 22, so that the height of the first vibrating tray 22 on the frame 1 is higher than the height of the discharging member 24 on the frame 1. When the first feeding mechanism 2 feeds materials, the staff places the screw in the first vibrating tray 22. As the first vibrating tray 22 continuously vibrates, the screw sequentially enters the discharging member 24 through the connecting pipe 23. When the material taking mechanism 4 takes materials, the material taking mechanism 4 clamps the screw from the discharging member 24 and moves it to the torsion bar assembly 52.

[0059] Please refer to Figure 5 , Figure 5 FIG. 10 is a schematic structural diagram of the discharging member. Further, the discharging member 24 includes an upper block 241, a connecting block 242, a lower block 243, a discharging cylinder 244, and a discharging column 245. The lower block 243 is arranged on the frame 1. One end of the connecting block 242 is connected to the lower block 243, and the other end is connected to the upper block 241. The upper block 241 and the lower block 243 are arranged at intervals. The upper block 241 is provided with a through hole 2411. The discharging cylinder 244 is installed in the through hole 2411 and communicates with the connecting pipe 23. The discharging column 245 is arranged on the lower block 243 and is opposite to the discharging cylinder 244. The discharging cylinder 244 has a first opening groove 2441, and the discharging column 245 has a second opening groove 2451. Both the first opening groove 2441 and the second opening groove 2451 open in the horizontal direction and have the same opening direction.

[0060] Specifically, the upper block 241, the connecting block 242, and the lower block 243 are arranged in sequence from top to bottom. The discharging cylinder 244 is arranged in the through hole 2411 of the upper block 241. The connecting pipe 23 communicates the first vibrating tray 22 and the discharging cylinder 244. The discharging cylinder 244 is opposite to the discharging column 245. The screw can slide from the connecting pipe 23 into the discharging cylinder 244. The discharging column 245 is located below the discharging cylinder 244. When the screw slides into the discharging cylinder 244, one end of the screw abuts against the discharging column 245, and the other end is located in the discharging cylinder 244, partially between the discharging column 245 and the discharging cylinder 244. The material moving mechanism can clamp the screw between the discharging column 245 and the discharging cylinder 244. After the material moving mechanism clamps the screw, the clamping mechanism drives the screw to move in the opening direction of the first opening groove 2441 and the second opening groove 2451, and the screw can be taken out from the discharging member 24.

[0061] Please refer to Figure 6 , Figure 6It is a schematic structural diagram of the material taking mechanism. Further, the material taking mechanism 4 includes a first driving component 41 and a material clamping component 42. The first driving component 41 is arranged on the frame 1, and the material clamping component 42 is arranged on the first driving component 41; the first driving component 41 drives the material clamping component 42 to move on the frame 1.

[0062] Specifically, the first driving component 41 can drive the material clamping component 42 to move horizontally or vertically on the frame 1. When the material clamping component 42 clamps, it can clamp the screw rod, and after loosening, the screw rod falls off from the clamping part 523.

[0063] Please refer to Figure 7 , Figure 7 It is a schematic structural diagram of the torsion bar mechanism. Further, the torsion bar assembly 52 includes a second driving part 521, a third driving part 522 and a clamping part 523. The second driving part 521 is arranged on the frame 1, the third driving part 522 is arranged on the second driving part 521, and the clamping part 523 is located on the rotation path of the feed inlet 5111 and is connected to the third driving part 522; the second driving part 521 drives the third driving part 522 to move along the direction of gravity, and the third driving part 522 drives the clamping part 523 to rotate.

[0064] Specifically, the second driving part 521 is used to drive the third driving part 522 to move vertically, that is, to drive the third driving part 522 to approach or move away from the carrier 511. The third driving part 522 is used to drive the clamping part 523 to rotate. The clamping part 523 is used to clamp the screw rod. After the first driving component 41 drives the material clamping component 42 to pick up the screw rod from the discharging part 24, the first driving component 41 continues to drive the material clamping component 42 to insert the screw rod into the clamping part 523.

[0065] Please refer to Figure 8 , Figure 8 It is a sectional view of the clamping part. Further, the clamping part 523 includes an outer cylinder 5231, a sliding cylinder 5232 and an elastic part 5233. The inner wall surface of the outer cylinder 5231 is provided with a limit protrusion 52311. The sliding cylinder 5232 includes a sliding part 52321 and a limit part 52322. The sliding part 52321 is connected to the limit part 52322. The sliding part 52321 is slidably arranged in the outer cylinder 5231. The limit part 52322 encloses to form an installation hole 52323, and the wall thickness of the limit part 52322 gradually increases from the end close to the limit protrusion 52311 to the end far from the limit protrusion 52311. The elastic part 5233 is arranged in the outer cylinder 5231, and its two ends are respectively abutted against the limit protrusion 52311 and the sliding part 52321.

[0066] Specifically, the elastic member 5233 is disposed between the limiting protrusion 52311 of the outer cylinder 5231 and the sliding portion 52321. The sliding cylinder 5232 is located inside the outer cylinder 5231. The limiting portion 52322 is slidably connected to the outer cylinder 5231, with a part of it inside the outer cylinder 5231 and a part outside the outer cylinder 5231. The limiting portion 52322 encloses to form a mounting hole 52323. When the clamping member 42 inserts the screw into the mounting hole 52323, the mounting hole 52323 can preliminarily clamp the screw. When the second driving member 521 drives the clamping member 523 to move towards the bearing member 511, after one end of the screw abuts against the bearing member 511, the sliding portion 52321 slides along the outer cylinder 5231 and squeezes the elastic member 5233, and the limiting portion 52322 slides into the outer cylinder 5231. The mounting hole 52323 gradually shrinks under the extrusion of the inner wall of the outer cylinder 5231, and the screw is tightly clamped by the mounting hole 52323. At this time, the third driving member 522 can drive the screw to rotate and twist the screw into the screw hole of the card.

[0067] Please refer to Figure 9 and Figure 10 , Figure 9 which is a schematic structural diagram of the liquid dipping mechanism. Figure 10

[0068] is a schematic diagram of the matching relationship between the second feeding mechanism and the torsion bar mechanism. Further, the screw twisting device further includes a liquid dipping mechanism 6. The liquid dipping mechanism includes a second bracket 61, a fourth driving member 62 and a liquid dipping tray 63. The second bracket 61 is disposed on the frame 1. The fourth driving member 62 is disposed on the second bracket 61. The liquid dipping tray 63 is disposed on the second driving member 521, and the second driving member 521 drives the liquid dipping tray 63 to move horizontally on the frame 1.

[0069] Specifically, the liquid dipping mechanism 6 is used to hold the lubricating liquid. After one end of the screw is dipped in the liquid and then twisted into the card, it can reduce the generation of metal chips and extra heat. The second bracket 61 is used to elevate the fourth driving member 62 and the liquid dipping tray 63. The fourth driving member 62 can drive the liquid dipping tray 63 to move between the feeding port 5111 and the torsion bar assembly 52. After the torsion bar assembly 52 receives the screw installed by the material taking mechanism 4, the second driving member 521 first drives the clamping member 523 to move towards the bearing member 511, so that one end of the screw is immersed in the liquid dipping tray 63, and then drives the clamping member 523 to move away from the bearing member 511, so that one end of the screw exits the liquid dipping tray 63. Then the fourth driving member 62 drives the liquid dipping tray 63 to reset, and then the second driving member 521 drives the clamping member 523 to move towards the bearing member 511 again, so that the screw abuts against the bearing member 511.

[0070] Further, the carrier is provided with a plurality of feeding ports 5111, and the plurality of feeding ports 5111 are arranged at intervals along the circumferential direction of the carrier 511.

[0071] Further, the pusher 512 includes a fifth driving member 5121 and a push pin 5122. The fifth driving member 5121 is arranged on the frame 1, the push pin 5122 is connected to the fifth driving member 5121, and the second feeding mechanism 3, the push pin 5122 and the discharging chute 11 are sequentially located on the rotation path of the feeding port 5111.

[0072] In summary, by setting the first feeding mechanism and the second feeding mechanism to feed the screw and the card respectively, the picking mechanism transfers the screw fed by the first feeding mechanism to the torsion bar assembly. The feeding port of the carrier first rotates to the second feeding mechanism to carry the card, and then rotates to the pusher. The pusher pushes the card into the feeding port to prevent the card from moving or being misaligned in the feeding port during the rotation of the carrier. Then, the torsion bar assembly twists the screw onto the card. Finally, the carrier rotates to the discharging chute to discharge the card with the twisted screw, realizing the automatic process of twisting the screw onto the card and improving the assembly efficiency of the fastener.
