[0071] The server provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0072] Embodiment 1:

[0073] As Figures 1 to 4 shown, the embodiment of the present application provides a feeding mechanism, including: a frame 1, a material 2, a plurality of suction cups 3, a plurality of hoppers 4, and a feeding device 5. It further includes: a transmission unit 6, which is arranged on the frame 1 and is used to drive each suction cup 3 to sequentially adsorb the material 2 and repeatedly transport it between the feeding device 5 and the next external device.

[0074] Furthermore, the transmission unit 6 includes: a turntable shaft 7, which is movably installed on the frame 1 and driven by a motor to rotate; a disc 8, which is fixedly installed at the lower end of the turntable shaft 7; and a plurality of lifting components 9, which are evenly distributed at the lower end of the disc 8 for lifting and adjusting the positions of the suction cups 3.

[0075] Furthermore, the lifting component 9 includes: an upper pressing cover cam 10, which is fixedly installed on the frame 1; a ring groove 11, which is arranged on the circumferential side wall of the upper pressing cover cam 10; and a plurality of connecting frame components 12, which are respectively movably and liftably installed on the disc 8, and the tops of which are all slidably engaged with the ring groove 11. Among them, the ring groove 11 includes a highest area 1101 and a lowest area 1102. When the connecting frame component 12 moves to the highest area 1101, it drives the suction cup 3 to move upward, and when the connecting frame component 12 moves to the lowest area 1102, it drives the suction cup 3 to move downward.

[0076] Furthermore, the connecting frame component 12 includes: an L-shaped connecting block 13, which is liftably inserted through the disc 8, and the bent end of which can slide along the ring groove 11; an intermediate sliding plate 14, which is fixedly installed at the bottom end of the L-shaped connecting block 13; a pair of adjusting rods 15, the upper ends of which are respectively movably and liftably installed on the intermediate sliding plate 14; a lower fixing plate 16, which is fixedly installed at the lower ends of the pair of adjusting rods 15 for installing the suction cup 3; a pair of scissor lifting frames 17, the middle shafts of which are respectively fixedly installed on both sides of the intermediate sliding plate 14, the upper two ends of which are respectively movably connected to the disc 8 through a pair of upper rocker arms, and the lower two ends of which are respectively movably connected to the lower fixing plate 16 through a pair of lower rocker arms; and a needle roller bearing 18, which is used for the rolling friction fit between the L-shaped connecting block 13 and the ring groove 11.

[0077] including the following steps

[0078] S1. Feeding: Place the material 2 in the hopper 4 to be moved to the loading position. The hopper 4 is moved to below the suction cup 3 through the cooperation of the turntable 19 and the corresponding motor.

[0079] S2. Loading: The lifting control mechanism 29 operates to engage the upper clutch body 25 and the lower clutch body 28. The motor corresponding to the spline shaft 27 runs, the single-head lead screw 24 rotates, and the pushing plate 21 rises, moving the material 1 to the loading position.

[0080] S3. Material transportation: The material 2 at the top of the hopper 4 is adsorbed by the suction cup 3. The motor corresponding to the disc 8 rotates, and the suction cup 3 rotates to above the next external device and releases the adsorption of the material 2.

[0081] S4. Repeating loading: The motor corresponding to the spline shaft 27 runs, the single-head lead screw 24 rotates, and the pushing plate 21 rises, moving the material 1 to the loading position.

[0082] S5. Repeated material transportation: The material 2 at the suction end of the bin hopper 4 is adsorbed by the suction cup 3. The suction cup 3 rotates through the disc 8 to the upper part of the next external device and releases the adsorption of the material 2.

[0083] S6. Repeat steps S4 - S5 until the material 2 in the bin hopper 4 at this position is emptied, and then enter step S7.

[0084] S7. Reset: The spline shaft 27 rotates reversely driven by the corresponding motor, and the pushing plate 21 moves down along the single - start lead screw 24 to the original position.

[0085] S8. Return to step S1 until the blanking is completed, and all motors stop running.

[0086] In this embodiment of the present application, due to the adoption of the above - mentioned structure, when it is necessary to adsorb the material 2, the motor drives the turntable 19 shaft 7 and the disc 8 to rotate so that the suction cup 3 moves to the upper part of the bin hopper 4. At the same time, the bent end of the L - shaped connecting rod 13 slides to the lowest area 1102 corresponding to the ring groove 11 and the bin hopper 4. During this process, the L - shaped connecting rod 13, the intermediate slide plate 14 and the scissor lift 17 descend. When the scissor lift 17 descends, it pulls the upper swing arm to swing and expands itself, thereby increasing the distance between the disc 8 and the intermediate slide plate 14. The lower swing arm swings with the expansion of the scissor lift 17, causing the lower fixed plate to descend. The lower fixed plate drives the suction cup 3 to move downward to the upper part of the bin hopper 4 to adsorb the material 2.

[0087] When it is necessary to transport the material 2 to the next external device, as the disc 8 rotates, the suction cup 3 adsorbed with the material 2 rotates to the upper part of the external device and then stops. During this process, the bent end of the L - shaped connecting rod 13 slides along the ring groove 11 from the lowest area 1102 far from the external device to the highest area 1101 and then to the lowest area 1102 corresponding to the external device. During the process of the L - shaped connecting rod 13 sliding to the highest area 1101, while the L - shaped connecting rod 13 moves upward, it drives the intermediate slide plate 14 and the scissor lift 17 to move upward. The lower swing arm drives the lower fixed plate to move upward with the movement of the scissor lift 17. The lower fixed plate drives the suction cup 3 to move upward to adsorb the material 2 it adsorbs from the top of the bin hopper 4, and then slides along the ring groove 11 to the highest area 1101 and then to the lowest area 1102 corresponding to the external device. When the suction cup 3 rotates to the lowest area 1102 corresponding to the external device, the suction cup 3 releases the material 2 again, so that the material 2 falls onto the external device.

[0088] Embodiment 2:

[0089] Such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5As shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, it further includes: The feeding device 5 includes: a turntable 19, which is movably installed on the frame 1 and is driven to rotate by a motor; an upper disc cover 20, which is arranged above the turntable 19; several pushing plates 21, which can be respectively lifted and lowered in each hopper 4; several screw lifting devices 22, which are evenly distributed on the turntable 19 for driving the corresponding pushing plates 21 to lift and lower; a power device 23, which is used to drive each screw lifting device 22 to operate.

[0090] Furthermore, the screw lifting device 22 includes: a single-threaded screw rod 24, which is rotatably installed between the upper disc cover 20 and the turntable 19, and its lower end passes through the lower part of the turntable 19; a clutch upper main body 25, which is fixedly installed at the lower end of the single-threaded screw rod 24; a connecting block 26, which is installed on the single-threaded screw rod 24 through a threaded hole; wherein, one end of the pushing plate 21 extends out of the hopper 4 and is fixedly connected to the connecting block 26.

[0091] Furthermore, the power device 23 includes: a spline shaft 27, which is rotatably installed on the frame 1 and is driven to rotate by a motor; a clutch lower main body 28, which is sleeved on the upper end of the spline shaft 27 through a transmission groove 31 and can be lifted and lowered, and is located below the clutch upper main body 25 at the material suction position of the suction cup 3, and can cooperate to drive the clutch upper main body 25 to rotate; a lifting control mechanism 29, which can drive the clutch lower main body 28 to lift and lower; a socket 34, which is arranged on the clutch upper main body 25; a steel ball 35, which is movably installed at the bottom end of the socket 34; a spring A 36, which is installed in the groove of the socket 34 through a stud and presses the steel ball 35 against the outlet; a concave cavity 37, which is arranged at the upper end of the clutch lower main body 28, wherein the steel ball 35 can be cooperatively installed in the concave cavity 37.

[0092] Furthermore, the lifting control mechanism 29 includes: an upper top base 30, which is fixedly installed between the turntable 19 and the frame 1; a transmission groove 31, which is arranged on the circumferential side wall of the clutch lower main body 28; an upper top frame 32, the middle part of which is rotatably installed on the upper top base 30 through a hinge frame, one end is in sliding transmission with the transmission groove 31, and the other end is driven to swing by a cylinder; a spring B 33, which is sleeved on the circumferential side of the spline shaft 27, and the top end and the bottom end are respectively abutted against the bottom end of the clutch lower main body 28 and the top surface of the upper top base 30.

[0093] In this embodiment of the present application, due to the adoption of the above structure, the material 2 is stacked on the pushing plate 21 of the silo hopper 4. When the turntable 19 rotates to move the silo hopper 4 filled with the material 2 to the lower end of the suction cup 3, when it is necessary to push the material 2 in the silo hopper 4 upward, the air cylinder retracts to move the upper support frame 32 upward, and the spring B33 releases pressure to push the lower clutch body 28 upward to cooperate with the upper clutch body 25. The motor drives the spline shaft 27 to drive the lower clutch body 28 to rotate. The concave cavity 37 is rotated to the position of the steel ball 35. The spring A36 presses against the steel ball 35 and is installed in the concave cavity 37. The upper clutch body 25 rotates with the rotation of the lower clutch body 28, thereby driving the single-head screw rod 24 at the upper end of the upper clutch body 25 to rotate. The rotation of the single-head screw rod 24 drives the connecting block 26 to move upward, and the pushing plate 21 pushes the material 2 in the silo hopper 4 upward to the top of the silo hopper 4 for the suction cup 3 to adsorb. When the material 2 in the first silo hopper 4 is completely adsorbed and it is necessary to restore the pushing plate 21 to the initial position, the motor drives the spline shaft 27 to rotate in the reverse direction. The single-head screw rod 24 rotates in the reverse direction to move the pushing plate 21 downward to the original position. The air cylinder pushes upward to make the outer end of the upper support frame 32 swing downward. The spring B33 contracts to drive the lower clutch body 28 to move downward, separating the lower clutch body 28 from the upper clutch body 25. The turntable 19 rotates to move the second silo hopper 4 under the suction cup 3, and repeating the above actions can completely adsorb the material 2 in each silo hopper 4.

[0094] There are two power devices. One is located below the suction position of the suction cup 3 and is specifically used to lift the corresponding pushing plate 21. The other is used to cooperate with the lower clutch body 28 that is not located below the suction position of the suction cup 3 and is specifically used to lower the corresponding pushing plate 21.

6. A conveying method suitable for the feeding mechanism according to claim 5, characterized in that, It includes the following steps: S1. Feeding: Place the material (2) into the hopper (4) to be moved to the feeding position. The hopper (4) is moved below the suction cup (3) through the cooperation of the turntable (19) and the corresponding motor; S2. Loading: The lifting control mechanism (29) operates to engage the upper clutch body (25) and the lower clutch body (28), the motor corresponding to the spline shaft (27) operates, the single-head lead screw (24) rotates, and the pushing plate (21) rises, moving the material to the loading position; S3. Transporting: The material (2) at the top of the hopper (4) is adsorbed by the suction cup (3), the motor corresponding to the disc (8) rotates, and the suction cup (3) rotates above the next external device and releases the adsorption of the material (2); S4. Repeating loading: The motor corresponding to the spline shaft (27) operates, the single-head lead screw (24) rotates, the pushing plate (21) rises, and the material moves to the loading position; S5. Repeating transporting: The material (2) at the suction end of the hopper (4) is adsorbed by the suction cup (3), and the suction cup (3) rotates above the next external device after passing the disc (8) and releases the adsorption of the material (2); S6. Repeat steps S4 - S5 until the material (2) in the hopper (4) at this position is emptied, and enter step S7; S7. Resetting: The spline shaft (27) reversely rotates under the drive of the corresponding motor, and the pushing plate (21) moves down along the single-head lead screw (24) to the original position; S8. Return to step S1 until the discharging is completed, and all motors stop running.
