Description

Technical Field

[0001] This utility model relates to a material handling and arrangement mechanism for umbrella head screws. Background Technology

[0002] Umbrella head screws are a type of fastener with a rounded top and a flat bottom. The rounded head reduces the impact force on the screw head when it is hit, and also prevents scratches from the circumference of the screw head to others or other objects.

[0003] In the production and processing of umbrella-head screws, the umbrella-head screws are placed flat in the jig tray. However, the arc-shaped screw head makes it impossible for the robotic arm to directly grasp the umbrella-head screws from the jig tray. The umbrella-head screws must be picked up one by one by manual labor and placed upright on a flat conveyor before proceeding to the next processing step, which leads to low production efficiency and wasted manpower. Utility Model Content

[0004] This utility model proposes an umbrella head screw picking and arranging mechanism, which can pick up a plurality of umbrella head screws laid flat, and can arrange the umbrella head screws upright and place them in a conveying mechanism.

[0005] The umbrella head screw feeding and arranging mechanism proposed in this utility model has the following characteristics:

[0006] A material handling mechanism, which has:

[0007] A material handling unit that can magnetically attract the screw rod of the umbrella head screw;

[0008] A rotating shaft, around which the material handling unit can rotate;

[0009] A first driving mechanism, which can drive the material taking part to rotate about the rotating shaft as the axis;

[0010] A clamping mechanism, wherein the material-grabbing part of the material-grabbing mechanism is rotatable to face the clamping mechanism; the clamping mechanism has:

[0011] A clamping part, when the material taking part of the material taking mechanism rotates to face the clamping mechanism, the clamping part faces the material taking part; the clamping part and the material taking part can be used to jointly clamp the screw of the umbrella head screw;

[0012] A second driving mechanism that can drive the clamping part to move relative to the picking part;

[0013] A transfer mechanism, movable relative to the picking mechanism and the clamping mechanism, and having:

[0014] A magnetic attraction part that can selectively generate magnetic force and selectively attract the screw head of the umbrella head screw with magnetic force;

[0015] A third driving mechanism is provided, which can drive the magnetic suction part to move relative to the material picking mechanism and the clamping mechanism; when the magnetic suction part approaches the clamping part and the material picking part, the magnetic suction part can generate magnetic force and magnetically attract the screw head of the umbrella head screw between the clamping part and the material picking part;

[0016] A transfer guide rail is provided, and the transfer mechanism is disposed on the transfer guide rail and can move along the transfer guide rail to above the conveying mechanism; when the transfer mechanism is above the conveying mechanism, the magnetic force of the magnetic suction part disappears, and the umbrella head screw falls into the conveying mechanism;

[0017] The material-grabbing mechanism can be in a picking state and a clamping state; when the material-grabbing mechanism is in the picking state, the picking part rotates to face downward; when the material-grabbing mechanism is in the clamping state, the picking part rotates to face the clamping mechanism.

[0018] The advantage of this invention lies in its ability to magnetically attract and upright umbrella-head screws laid flat using a material-grabbing mechanism, with the screws held and stabilized by both a clamping mechanism and the material-grabbing mechanism. Next, the magnetic attraction part of the transfer mechanism magnetically attracts the screw head. Finally, the transfer mechanism moves above the conveying mechanism and the magnetic attraction part is deactivated, allowing the umbrella-head screws to fall into the conveying mechanism and stand upright. Therefore, during the production and processing of umbrella-head screws, it is unnecessary to manually pick up and upright each screw individually, saving time and labor costs and improving production efficiency.

[0019] As described above, in the umbrella head screw feeding and arranging mechanism, the clamping part has:

[0020] One clamping surface faces the material handling mechanism;

[0021] A plurality of clamping grooves are recessed into the clamping surface; when the clamping part and the material taking part jointly clamp the screw of the umbrella head screw, the screw of the umbrella head screw is respectively located in the clamping groove.

[0022] As described above, in the umbrella head screw feeding and arranging mechanism, the magnetic suction part has:

[0023] A magnetic suction surface is provided, which faces the clamping part and the picking part when the magnetic suction part approaches the clamping part and the picking part.

[0024] Multiple magnetic grooves are recessed into the magnetic surface; when the magnetic part magnetically attracts the umbrella head screw, the screw head of the umbrella head screw is located in the magnetic groove.

[0025] As described above, in the umbrella head screw feeding and arranging mechanism, the transfer mechanism has:

[0026] A magnetic component is movable relative to the magnetic attraction portion; when the magnetic component moves to contact the magnetic attraction portion, the magnetic attraction portion generates a magnetic force; when the magnetic component moves to separate from the magnetic attraction portion, the magnetic force of the magnetic attraction portion disappears.

[0027] As described above, in the umbrella head screw feeding and arranging mechanism, the transfer mechanism has:

[0028] A fourth driving mechanism is connected to the magnetic component and can drive the magnetic component to approach or move away from the magnetic attraction part.

[0029] As described above, the umbrella head screw feeding and arranging mechanism has the following features:

[0030] A linear slide rail is provided, and the material-picking part can move along the linear slide rail. When the material-picking mechanism is in the clamping state, the material-picking part can approach or move away from the clamping mechanism along the linear slide rail. When the material-picking mechanism is in the picking state, the material-picking part faces downward and can move upward or downward along the linear slide rail.

[0031] In the umbrella head screw picking and arranging mechanism described above, the magnetic force generated by the magnetic attraction part of the transfer mechanism is greater than the magnetic force of the picking part of the picking mechanism. Attached Figure Description

Detailed Implementation

[0043] Please refer to Figure 1 This utility model proposes a screw-picking and arranging mechanism for umbrella heads, which can pick up a plurality of umbrella head screws A and arrange them in a conveying mechanism B. In this embodiment, the screw-picking and arranging mechanism can pick up flat umbrella head screws A from a tool tray C and place them upright in the conveying mechanism B, but is not limited thereto. The screw-picking and arranging mechanism includes a picking mechanism 10, a clamping mechanism 20, a transfer mechanism 30, and a transfer guide rail 40.

[0044] Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7The material handling mechanism 10 can be in a picking state and a clamping state, and has a picking part 11, a rotating shaft 12, a first drive mechanism 13, and a linear slide rail 14. The picking part 11 is movably disposed at one end of the material handling mechanism 10. Specifically, the picking part 11 can move along the linear slide rail 14, and the picking part 11 and the linear slide rail 14 can rotate about the rotating shaft 12. In this embodiment, the picking part 11 is a magnet and can magnetically attract the screw of the umbrella head screw A. The first drive mechanism 13 can drive the picking part 11 and the linear slide rail 14 to rotate about the rotating shaft 12. When the material handling mechanism 10 is in the picking state, the first drive mechanism 13 drives the picking part 11 to rotate downward, at which time the picking part 11 faces downward and can move upward or downward along the linear slide rail 14. When the material handling mechanism 10 is in the clamping state, the first drive mechanism 13 drives the material handling part 11 to rotate toward the clamping mechanism 20. At this time, the material handling part 11 can move along the linear slide rail 14 to approach or move away from the clamping mechanism 20.

[0045] Please refer to Figure 1 , Figure 3 and Figure 7 The clamping mechanism 20 has a clamping portion 21 and a second driving mechanism 22. The clamping portion 21 is movably disposed at one end of the clamping mechanism 20, and when the picking portion 11 of the picking mechanism 10 rotates to face the clamping mechanism 20, the clamping portion 21 faces the picking portion 11. The second driving mechanism 22 can drive the clamping portion 21 to move relative to the picking portion 11, so that the clamping portion 21 approaches or moves away from the picking portion 11. When the clamping portion 21 approaches the picking portion 11, the clamping portion 21 and the picking portion 11 can jointly clamp the screw of the umbrella head screw A. In this embodiment, the clamping portion 21 has a clamping surface 211 and a plurality of clamping grooves 212. The clamping surface 211 is the side of the clamping portion 21 facing the picking mechanism 10. The clamping grooves 212 are recessed in the clamping surface 211 and are arranged parallel to each other. When the clamping part 21 and the material taking part 11 jointly clamp the screw of the umbrella head screw A, the screw of the umbrella head screw A is located in the clamping groove 212.

[0046] Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 8The transfer mechanism 30 is movable relative to the picking mechanism 10 and the clamping mechanism 20, and includes a magnetic suction part 31, a magnetic element 32, a third drive mechanism 33, and a fourth drive mechanism 34. The magnetic suction part 31 is movably disposed at one end of the transfer mechanism 30 and can selectively generate magnetic force, thereby selectively attracting the screw head of the umbrella-head screw A with magnetic force. The third drive mechanism 33 can drive the magnetic suction part 31 to move relative to the picking mechanism 10 and the clamping mechanism 20, and cause the magnetic suction part 31 to approach or move away from the picking mechanism 10 and the clamping mechanism 20. When the magnetic suction part 31 approaches the clamping part 21 and the picking part 11, the magnetic suction part 31 generates magnetic force and attracts the screw head of the umbrella-head screw A between the clamping part 21 and the picking part 11 with magnetic force. Specifically, in this embodiment, the magnetic suction part 31 is a magnetic metal, the magnetic element 32 is a magnet, and the magnetic element 32 is movable relative to the magnetic suction part 31. When the magnetic component 32 moves to contact the magnetic suction part 31, the magnetic suction part 31 generates a magnetic force and can magnetically attract the screw head of the umbrella-head screw A. When the magnetic component 32 moves to separate from the magnetic suction part 31, the magnetic force of the magnetic suction part 31 disappears. In this embodiment, the magnetic suction part 31 has a magnetic suction surface 311 and a plurality of magnetic suction grooves 312. When the magnetic suction part 31 approaches the clamping part 21 and the picking part 11, the magnetic suction surface 311 faces the clamping part 21 and the picking part 11. The magnetic suction grooves 312 are recessed in the magnetic suction surface 311. When the magnetic suction part 31 magnetically attracts the umbrella-head screw A, the screw head of the umbrella-head screw A is located in the magnetic suction groove 312.

[0047] Please refer to Figure 9 and Figure 10 The transfer mechanism 30 is mounted on the transfer guide rail 40 and can move along the transfer guide rail 40 to approach the material handling mechanism 10 and the clamping mechanism 20, or move above the conveying mechanism B. When the transfer mechanism 30 is above the conveying mechanism B, the fourth drive mechanism 34 drives the magnetic component 32 to rise, causing the magnetic force of the magnetic attraction part 31 to disappear, and causing the umbrella head screw A to fall into the conveying mechanism B.

[0048] In this embodiment, the picking part 11 of the picking mechanism 10 is a magnet. The magnetic attraction part 31 of the transfer mechanism 30 is a magnetic metal, and the magnetic element 32 is a magnet. By controlling the magnetic element 32 to approach or move away from the magnetic attraction part 31, the magnetic attraction part 31 generates or eliminates magnetic force. The magnetic force generated by the magnetic attraction part 31 of the transfer mechanism 30 is greater than the magnetic force of the picking part 11 of the picking mechanism 10. In other embodiments, the transfer mechanism 30 may not have a magnetic element 32, and the picking part 11 of the picking mechanism 10 and the magnetic attraction part 31 of the transfer mechanism 30 may be electromagnets, but this is not a limitation.

[0049] Please refer to Figure 1 and Figures 6 to 10First, the first drive mechanism 13 of the picking mechanism 10 drives the picking part 11 to rotate downwards, putting the picking mechanism 10 into a picking state. At this time, the picking part 11 can move downwards along the linear slide rail 14 and magnetically pick up the screw of the umbrella-head screw A lying flat in the fixture plate C. Next, the picking part 11 can move upwards along the linear slide rail 14, and the first drive mechanism 13 drives the picking part 11 to rotate towards the clamping mechanism 20, putting the picking mechanism 10 into a clamping state. Subsequently, the picking part 11 moves along the linear slide rail 14 to approach the clamping mechanism 20. At the same time, the second drive mechanism 22 of the clamping mechanism 20 drives the clamping part 21 to approach the picking part 11, so that the clamping part 21 and the picking part 11 jointly clamp the screw of the umbrella-head screw A. Then, the third drive mechanism 33 of the transfer mechanism 30 drives the magnetic suction part 31 to approach the picking mechanism 10 and the clamping mechanism 20. At this point, the magnetic component 32 contacts the magnetic suction part 31, thereby generating a magnetic force in the magnetic suction part 31 and magnetically attracting the screw head of the umbrella-head screw A. Subsequently, the third drive mechanism 33 drives the magnetic suction part 31 away from the picking mechanism 10 and the clamping mechanism 20, and the picking part 11 moves along the linear slide rail 14 away from the clamping mechanism 20. The second drive mechanism 22 drives the clamping part 21 away from the picking part 11, thereby causing the umbrella-head screw A to detach from the picking mechanism 10 and the clamping mechanism 20 and magnetically attach to the magnetic suction part 31 of the transfer mechanism 30. Finally, the transfer mechanism 30 moves along the transfer guide rail 40 above the conveying mechanism B. When the transfer mechanism 30 is above the conveying mechanism B, the magnetic component 32 separates from the magnetic suction part 31, and the magnetic force of the magnetic suction part 31 disappears, causing the umbrella-head screw A to fall into the conveying mechanism B and be conveyed to the next processing procedure.

[0050] The advantage of this invention is that the picking mechanism 10 can magnetically attract and upright the flat umbrella-head screw A, and the clamping mechanism 20 and the picking mechanism 10 together hold and stabilize the umbrella-head screw A. Then, the magnetic suction part 31 of the transfer mechanism 30 can magnetically attract the screw head of the umbrella-head screw A. Finally, the transfer mechanism 30 moves above the conveying mechanism B and the magnetic force of the magnetic suction part 31 is released, allowing the umbrella-head screw A to fall into the conveying mechanism B and be upright. Therefore, during the production process of the umbrella-head screw A, it is not necessary to manually pick up and upright each umbrella-head screw A, saving time and labor costs and improving production efficiency.
