Description

Technical Field

[0001] This utility model relates to a feeding mechanism and belongs to the technical field of feeding equipment. Background Technology

[0002] In existing technologies, bolts, threaded sleeves, or nuts are often fed using a vibratory feeder or ductwork, and then removed by a gripper assembly or robotic arm for further processing. Sometimes, they need to be transported to an assembly station, and sometimes they need to be further processed or inspected. Existing feeding mechanisms have the following drawbacks: when bolts or nuts move under the action of the vibrator, adjacent bolts or nuts tend to stick together. When removed by a robotic arm, gripper assembly, or suction cup, the next part to be removed is easily pulled up, making sequential material handling difficult and increasing the risk of bolts falling off.

[0003] Therefore, the research objective of this utility model is to provide a feeding mechanism that can sequentially pick up materials and clamp them stably. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides a feeding mechanism that sequentially feeds bolts or nuts to pneumatic grippers via a receiving seat, and then uses a lifting cylinder to transport the bolts or nuts from the pneumatic grippers to the next workstation, thereby achieving the purpose of sequential material handling.

[0005] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows:

[0006] A feeding mechanism includes a frame, a discharge pipe fixedly provided on one side of the frame, a receiving seat movably provided below the discharge pipe, a receiving part provided on the receiving seat, the receiving part being aligned with the bottom end of the discharge pipe; a lifting plate is also provided on the frame via a slide rail slider, a gripper moving cylinder is provided on the lifting plate, the output end of the gripper moving cylinder is connected to a pneumatic gripper, the pneumatic gripper being able to extend to the receiving part under the drive of the gripper moving cylinder.

[0007] Furthermore, the receiving seat is located on one side of the bottom of the frame via a slide rail slider, and a receiving seat moving cylinder is connected to one side of the receiving seat to drive its movement.

[0008] Furthermore, the bottom of the lifting plate is connected to a lifting cylinder that drives its lifting and lowering, and the top of the frame is provided with a proximity switch for detecting the position of the lifting plate.

[0009] Furthermore, a convex shaft is fixedly provided on the lifting plate, and the gripper moving cylinder is rotatably mounted on the convex shaft via a clamping plate. The clamping plate is provided with a through hole that is interference-fitted with the convex shaft.

[0010] Furthermore, the bottom of the receiving part is provided with a receiving hole, and the bottom end of the receiving hole is connected to an air inlet pipe connector.

[0011] Furthermore, the output end of the pneumatic gripper is provided with two sets of symmetrically arranged gripping parts, and the bottom end of each set of gripping parts is provided with a semi-circular gripping groove.

[0012] The beneficial effects of this utility model are: 1. Bolts or nuts are sequentially conveyed to the pneumatic gripper for clamping via a receiving seat, and the bolts or nuts on the pneumatic gripper are conveyed to the next workstation via a lifting cylinder, thus achieving the purpose of sequential material removal; 2. An air inlet pipe connector is connected to the bottom of the receiving part. After connecting to an external air source, the bolts or nuts in the receiving part can be blown up, and the top of the bolts or nuts can be brought into contact with the gripping part of the pneumatic gripper, making it easier for the pneumatic gripper to remove the bolts or nuts; 3. A semi-circular clamping groove matching the top of the bolts or nuts is provided at the bottom of the gripping part, making it less likely for the pneumatic gripper to drop the bolts or nuts when it is clamped, and making the clamping more stable.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-8 Further analysis of this utility model is then conducted.

[0023] like Figure 1-8 As shown, a feeding mechanism includes a frame 1. A dropping pipe 2 is fixedly provided on one side of the frame 1. The top end of the dropping pipe 2 is connected to the discharge end of an external vibrating dropping plate or a linear vibrating dropping device via a flexible hose, and is connected to an external air duct to blow bolts or nuts and other parts from the flexible hose into the dropping pipe 2. A receiving seat 3 is movably provided below the dropping pipe 2. The receiving seat 3 is provided with a receiving part 301, which is aligned with the bottom end of the dropping pipe 2 and is used to receive bolts or nuts and other parts falling from the dropping pipe 2. A lifting plate 4 is also provided on the frame 1 via a slide rail slider. A gripper moving cylinder 5 is provided on the lifting plate 4. The output end of the gripper moving cylinder 5 is connected to a pneumatic gripper 6. The pneumatic gripper 6 can extend to the receiving part 301 under the drive of the gripper moving cylinder 5.

[0024] In this embodiment, preferably, the receiving seat 3 is disposed on one side of the bottom of the frame 1 via a slide rail slider, and a receiving seat moving cylinder 7 for driving its movement is connected to one side of the receiving seat 3.

[0025] In this embodiment, preferably, the bottom of the lifting plate 4 is connected to a lifting cylinder 8 that drives its lifting and lowering, and the top of the frame 1 is provided with a proximity switch 9 for detecting the position of the lifting plate 4.

[0026] In this embodiment, preferably, a convex shaft 401 is fixedly provided on the lifting plate 4. The gripper moving cylinder 5 is rotatably mounted on the convex shaft 401 via a clamping plate 10, and is used to finely adjust the direction of the pneumatic gripper 6 so that it more accurately points to the top of the bolt or nut or other parts at the receiving part 301. The clamping plate 10 is provided with a through hole 1001 that is interference-fitted with the convex shaft 401. In order to facilitate the adjustment of the tightness between the clamping plate 10 and the convex shaft 401, a slot extending to the outside of the clamping plate 10 is also provided on one side of the through hole 1001. A bolt is provided in the slot for adjusting the tightness between the through hole 1001 and the convex shaft 401.

[0027] In this embodiment, preferably, the bottom of the receiving part 301 is provided with a receiving hole 301a, and the bottom end of the receiving hole 301a is connected to an air inlet pipe connector 11. The receiving hole 301a is used to accommodate the column structure of the bolt.

[0028] In this embodiment, preferably, the output end of the pneumatic gripper 6 is provided with two sets of symmetrically arranged gripping parts 601. The bottom end of each set of gripping parts 601 is provided with a semi-circular gripping groove 602. The semi-circular gripping groove 602 makes it less likely for the pneumatic gripper 6 to fall off when it grips bolts or nuts and other parts, and the gripping is more stable.

[0029] The working principle of this utility model is as follows: The top end of the discharge pipe 2 is connected to the discharge end of the discharge device via a flexible hose, and the hose is connected to an external air duct. Air pressure blows bolts or nuts and other parts from the hose into the discharge pipe 2. At this time, the receiving part 301 of the receiving seat 3 is located below the discharge pipe 2, catching the bolts or nuts and other parts falling from the discharge pipe 2. Then, the receiving seat moving cylinder 7 moves the receiving seat 3 to correspond with the pneumatic gripper 6. Finally, the gripper moving cylinder 5 drives the pneumatic gripper 6 to move towards the receiving part 3. The machine moves to position 01 and aligns the clamping part 601 with the top of the receiving part 301 for bolts or nuts. Then, it connects to an external air source through the air inlet pipe connector 11 to blow up the bolts or nuts on the receiving part 301, so that the top of the bolts or nuts contacts the clamping part 601. The pneumatic gripper 6 closes, and the clamping groove 602 clamps the top of the bolts or nuts, thereby clamping the bolts or nuts. Finally, the lifting cylinder 8 drives the lifting plate 4 to rise, which works with the gripper moving cylinder 5 to transport the bolts or nuts to the next work station.
