Description

Technical Field

[0001] This invention relates to a connecting ring processing system. Background Technology

[0002] Existing connecting rings typically consist of a screw and a nut. The screw is usually made of bent metal wire, with external threads at both ends. After bending, the two ends of the metal wire form a notch resembling the letter "C". The nut typically has internal threads. The screw and nut cooperate to form a sealed "O"-shaped connecting ring. In actual processing, both ends of the screw are threaded, but to limit the rotation of the nut and prevent excessive movement, one end has a radially outward-extending shoulder, usually called the large end, and the other end is called the small end. When attaching the nut, it is usually screwed to the small end and then rotated to the large end to seal the connecting ring. Therefore, the positions of the large and small ends of the screw must be ensured during screw loading. In addition, a reinforcing rib is usually provided at the shoulder of the large end. This reinforcing rib needs to be directionally limited to prevent twisting during the first and second bending of the screw, which would affect product performance. After the screw is bent twice, it is difficult to screw the nut from the small end to the large end. Therefore, existing connecting rings typically achieve one or some functions through a single setting, and some work requires the cooperation of workers. The equipment cannot achieve integrated processing of the connecting ring, resulting in low production efficiency, large equipment size, and high production costs. Summary of the Invention

[0038] The embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0039] Depend on Figure 1 Combination Figure 2-22 As shown, a connecting ring processing system includes a frame 1, and further includes:

[0040] Screw feeding device 2, installed on frame 1, is used for screw feeding;

[0041] Screw detection device 3 is installed on frame 1;

[0042] The first bending device 4 is mounted on the frame 1 and is used for the first bending of the screw. In this invention, the first bending device and the second bending device mainly make the screw bend, which can be achieved with existing technology and will not be described in detail here.

[0043] The upper nut device 5 is set on the frame 1 and is used for feeding nuts and screwing nuts on one end of the screw rod;

[0044] The second bending device 6 is installed on the frame 1 and is used for the second bending of the screw and to make the screw form a "C" shape.

[0045] A nut-tightening device 7, mounted on the frame 1, is used to tighten the nut at one end of the screw, causing the connecting ring to close into an "O" shape. The screw feeding device 2, screw detection device 3, first bending device 4, nut-attaching device 5, second bending device 6, and nut-tightening device 7 are connected sequentially. The advantages of this invention are that by incorporating the screw feeding device, screw detection device, first bending device, and second bending device, the screw is processed as a single unit. The nut is then attached using the nut-attaching and tightening devices, allowing the nut and screw to mate into a connecting ring. This simplifies processing, reduces size and footprint, increases production efficiency, and significantly lowers production costs. Furthermore, this invention offers advantages such as simple structure, convenient assembly, reliable operation, and long service life.

[0046] The present invention also includes a connecting ring detection device 8, mounted on the frame 1 and located behind the processing position of the nut-tightening device 7. The connecting ring detection device 8 includes a detection top block 81, which pushes the connecting ring vertically to detect the connecting ring processed by the nut-tightening device 7. Specifically, the connecting ring detection device includes a connecting ring detection clamp that holds the nut portion of the connecting ring. The detection top block pushes the screw upwards. If the screw falls freely, the connecting ring is a live hook and is placed in a live hook collection box. If the screw cannot fall freely, it is a dead hook. In this invention, the connecting ring detection device also includes a pull hook mechanism, which can pull the dead hook screw outwards, changing the relative position of the nut and screw, and then clamping it onto the connecting ring detection clamp for detection. If it is a live hook, it is placed in a live hook collection box; if it is a dead hook, it is placed in a dead hook collection box. This invention uses two checks on dead hooks before finally placing them into the dead hook collection box, reducing the amount of dead hooks and making detection convenient. The hook mechanism can also convert dead hooks into live hooks, making the structure simple and the operation convenient and reliable.

[0047] The screw detection device 3 includes:

[0048] A thread detection mechanism 31 is mounted on the frame 1. The thread detection mechanism 31 includes a thread detection sleeve 311 and a thread detection drive 312. The thread detection drive 312 is connected to the thread detection sleeve 311 and is used to drive the thread detection sleeve 311 to detect the thread on the screw.

[0049] The screw rib adjustment mechanism 32 is mounted on the frame 1 and is used to adjust the direction of the screw rib.

[0050] The screw transfer mechanism 33, mounted on the frame 1, is used to pick up material from the screw feeding device 2 and transfer the screw to the thread detection mechanism 31 and the screw rib adjustment mechanism 32. The thread detection mechanism can detect the quality of the threads on the screw, preventing defective threads from entering subsequent processing and increasing the amount of dead hooks.

[0051] The screw rib adjustment mechanism 32 includes a screw rib detection machine 321, a screw rib sleeve 322, and a screw rib sleeve drive 323. The screw rib sleeve drive 323 is connected to the screw rib sleeve 322 and drives the screw to rotate through the screw rib sleeve 322. The screw rib detection machine 321 is located above the screw rib sleeve 322 and faces the screw to control the movement of the screw rib sleeve drive 323. This invention allows the screw to rotate through the screw rib sleeve via the screw rib sleeve drive, so that the side of the screw with ribs faces upwards. The screw rib detection machine can detect the position of the ribs; more specifically, the screw rib detection machine is an industrial camera.

[0052] The upper nut device 5 includes:

[0053] The nut loading mechanism 51 is mounted on the frame 1 and is used for loading nuts.

[0054] The upper nut clamp 52 is provided on the frame 1 for clamping the screw;

[0055] The screw turning mechanism 53, mounted on the frame 1, is used to rotate the screw after the nut is screwed onto it. This structure facilitates the screwing of nuts, is simple in design, and is easy to operate.

[0056] The upper nut clamp 52 includes a horizontally arranged first guide finger 521 and a vertically arranged second guide finger 522. The first guide finger 521 and the second guide finger 522 slide relative to the frame 1 in the horizontal and vertical directions, respectively. The first guide finger 521 and the second guide finger 522 cooperate to form an upper nut mounting hole 523 for the screw to pass through and facilitate the rotation of the screw. The screw flipping mechanism 53 includes an upper nut rotating block 531 and an upper nut rotating block driving member 532. The upper nut rotating block 531 is driven by the upper nut rotating block driving member 532 and is used to drive the screw to rotate. The arrangement of the first guide finger and the second guide finger can cooperate to form the upper nut mounting hole, that is, to limit the screw in the horizontal and vertical directions, while also allowing reliable rotation, which facilitates the upper nut rotating block to push the screw to flip, and facilitates subsequent processing by the second bending device.

[0057] The screw feeding device 2 includes:

[0058] The feeding channel 21 is located on the frame 1 and connected to the vibratory plate, and is used to receive the screw 91 on the vibratory plate.

[0059] The screw feeding clamp 22 is mounted on the frame 1 and has a first position for easy loading and unloading of the screw and a second position for clamping the screw.

[0060] The screw direction confirmation mechanism 23 is mounted on the frame 1 and is used to confirm the direction of the screw on the screw feeding fixture.

[0061] The loading robot 24 has a first position for gripping the screw on the screw loading fixture 22, a second position for holding the screw, and a second position for unloading the screw. The beneficial effects of this invention are that it includes a screw loading fixture and a screw direction confirmation mechanism to confirm the screw's direction, facilitating screw direction adjustment and subsequent processing. This invention also has advantages such as simple structure, convenient assembly, reliable operation, and long service life.

[0062] The screw direction confirmation mechanism 23 includes:

[0063] The feeding confirmation sleeve 231 is used to insert one end of the screw to determine the screw position for subsequent processing.

[0064] The confirming movement component 232 is used to move the feeding confirming sleeve 231 closer to or further away from the screw feeding fixture. Specifically, the confirming movement component may include a motor (or a cylinder or other driving component) that drives the feeding confirming sleeve to rotate and a linear motion motor that drives the feeding confirming sleeve. This ensures that even if the feeding confirming sleeve and the screw are not perfectly concentric, it can reliably rotate back and forth, reducing the precision requirements of the equipment during processing and lowering costs.

[0065] The aforementioned loading robot 24 includes:

[0066] The feeding mechanical fingers 241 have a first position for clamping the screw and a second position for picking up and placing the screw.

[0067] The horizontal drive component 242 of the robotic arm is connected to the loading robotic finger 241 and is used to drive the loading robotic finger 241 to move horizontally.

[0068] A vertical drive unit 243 for the robotic arm is connected to the loading robotic finger 241 and is used to drive the loading robotic finger 241 to move vertically. Specifically, it also includes a robotic arm rotation drive unit 244, connected to the loading robotic finger 241, which drives the loading robotic finger 241 to rotate horizontally when the loading robotic arm 24 is in the second position. The setting of the loading robotic arm can transfer the screw when the screw's large and small ends are in the correct position, and when the screw's large and small ends are not in the correct position, the robotic arm rotation drive unit can rotate the screw horizontally by 180 degrees, thereby ensuring that the screw direction is consistent during loading, which is convenient for subsequent processing.

[0069] The present invention also includes a feeding base plate 211 and a feeding baffle 212, wherein the feeding baffle 212 is disposed above the feeding base plate 211, and the feeding base plate 211 is bent. The feeding baffle 212 and the feeding base plate 211 cooperate to form the feeding channel 21. The feeding channel formed in this way allows the screws to be stacked in multiple rows, and can reliably discharge materials, with a simple structure. The screw positioning is reliable.

[0070] The screw feeding fixture 22 includes:

[0071] Fixture base plate 221,

[0072] The first feeding clamping block 222 is provided on the clamp base plate 221, and the first feeding clamping block 222 is provided with a feeding blocking part 2221 that blocks the unloading channel 21.

[0073] The second feeding clamp 223 is mounted on the fixture base plate 221 and has a first position for easy loading and unloading of the screw and a second position for clamping the screw in conjunction with the first feeding clamp 222. The feeding shielding part is designed to block the unloading channel, enabling the screws to be fed one by one. The first and second feeding clamps cooperate with each other to quickly and reliably clamp the screws. The structure is simple and the operation is convenient and reliable.

[0074] The screw feeding fixture 22 includes:

[0075] The feeding clamp drive 224 is disposed on the clamp base plate 221 and connected to the second feeding clamp 223, and is used to drive the position change of the second feeding clamp 223;

[0076] The feeding fixture moving component 225 is connected to the fixture base plate 221 and is used to drive the fixture base plate 221 to move horizontally. This structure makes the fixture base plate move reliably and facilitates material receiving. The setting of the feeding fixture driving component facilitates reliable clamping of the screw, easy screw receiving, and easy screw direction confirmation.

[0077] The screw loading clamp 22 includes a first clamping movable block 226 and a second clamping movable block 227. The first clamping movable block 226 and the second clamping movable block 227 cooperate with each other through wedge-shaped surfaces and are used to drive the second loading clamping block 223 to move horizontally. Specifically, the first loading clamping block 222 is provided with a clamping block support part 2222 for supporting the screw, and the clamping base plate 221 is provided with a clamping guide pressure block 2211. The clamping guide pressure block 2211 cooperates with the second loading clamping block 223 to guide the movement of the second loading clamping block 223. This structure facilitates reliable cooperation between the second loading clamping block and the first loading clamping block to clamp the screw. The structure is simple and the operation is convenient and reliable.

[0078] The invention also includes a feeding support plate 25, which is mounted on the frame 1. The feeding support plate 25 is provided with a feeding receiving groove 251 for receiving the screw of the feeding robot 24. This structure facilitates material handling by subsequent devices and subsequent processing.

[0079] The nut tightening device includes a nut tightening bracket 71;

[0080] A nut mounting assembly 72 is provided on a nut holder 71, and the nut mounting assembly 72 is provided with a nut mounting groove 721 for vertical insertion of a connecting ring;

[0081] A nut-tightening component 73 is provided on the nut-tightening mounting assembly 72. The nut-tightening component 73 is provided with a nut-tightening notch 731, which is oriented toward the insertion direction of the nut-tightening mounting groove 721 connecting ring 9.

[0082] The nut tightening drive component 74 is mounted on the nut tightening bracket 71;

[0083] A nut-tightening transmission mechanism 75 is mounted on a nut-tightening bracket 71 and is driven by a nut-tightening drive component 74. The nut-tightening transmission mechanism 75 is connected to a nut-tightening component 73 and drives the nut-tightening component 73 to rotate circumferentially. The advantages of this invention are that it includes a nut-tightening component and a nut-tightening transmission mechanism. The nut-tightening transmission mechanism drives the nut-tightening component to rotate, thereby causing the nut to rotate and tighten. The structure is simple, the product is small in size, easy to operate, and reliable in action.

[0084] The nut-tightening notch 731 includes a nut-tightening drive groove 7311 that connects to the nut on the connecting ring 9 for driving the nut to rotate. The end of the nut-tightening notch 731 opens outward to form a nut-tightening guide groove 7312. The nut-tightening drive groove 7311 and the nut-tightening guide groove 7312 are connected. The nut component 73 is U-shaped. This structure allows the connecting ring to reliably and quickly fall into the nut-tightening notch when it is placed into the nut-tightening mounting groove. The nut-tightening drive groove reliably drives the nut to rotate, thereby rotating the nut located at the small end of the screw, causing the nut to move towards the large end of the screw and finally connect to the large end of the screw, closing the screw and forming an O-shaped connecting ring.

[0085] The nut tightening transmission mechanism 75 is a gear transmission assembly 751, and the outer surface of the nut tightening component 73 is provided with transmission teeth 732 that are adapted to the gear transmission assembly 751. Specifically, the nut tightening transmission mechanism 75 includes a main drive shaft 752, and the nut tightening drive component 74 is connected to the main drive shaft 752 and used to drive the main drive shaft 752 to rotate. The main drive shaft 752 is connected to the gear transmission assembly 751 and used to drive the gear transmission assembly 751 to rotate. The gear transmission assembly 751 includes multiple transmission gears 7511, and the transmission gears 7511 are located circumferentially on the nut tightening component 73 and used to drive the nut tightening component 73 to rotate. This invention drives the nut tightening component to rotate through a gear transmission assembly, which has a simple structure and can transmit greater torque. Specifically, the nut tightening drive component can drive the main rotating shaft to rotate through a reducer.

[0086] There are four transmission gears 7511, and the four transmission gears 7511 are arranged in pairs on both sides of the nut-tightening component 73, with the two transmission gears 7511 on the same side arranged symmetrically vertically. Specifically, the arrangement of the four transmission gears can make reasonable use of the space within the nut-tightening assembly. At the same time, the arrangement of two transmission gears on both sides of the nut-tightening component, with the two transmission gears on the same side arranged symmetrically vertically, ensures that the transmission gears can mesh with the transmission teeth regardless of the orientation of the nut notch during rotation, thereby driving the nut-tightening component to rotate reliably and tighten the nut.

[0087] The screw-on nut mounting slot 721 is arranged in a straight line, and the screw-on nut mounting assembly 72 has a screw-on nut guide surface 722 at the insertion direction of the connecting ring in the screw-on nut mounting slot 721. This structure facilitates the insertion of the "open" connecting ring (as opposed to the "O"-shaped closed connecting ring, the inserted connecting ring has a certain gap between the large end of the screw and the end of the nut) and facilitates product processing.

[0088] The nut mounting assembly 72 includes a nut mounting plate 723 and a nut baffle 724. The gear transmission assembly 751 is disposed within the space formed by the nut mounting plate 723 and the nut baffle 724. The nut baffle 724 has a nut transmission hole or nut transmission groove facing the nut notch 731 for the gear transmission assembly 751 to pass through. This structure facilitates the installation of bearings and gear transmission assemblies, reduces product size, avoids affecting the rotation of the nut, and features a simple structure with convenient and reliable rotation.

[0089] The present invention also includes a nut positioning mechanism 76, which includes a nut positioning block 761 and a nut positioning drive component 762 for driving the movement of the nut positioning block 761. The nut positioning block 761 has a first position for opening to facilitate the placement and removal of the connecting ring, and a second position for limiting the connecting ring after it enters the nut notch 731. Specifically, the nut positioning block 761 includes a nut-shaped arcuate portion 7611, which presses against the connecting ring and limits its position when the nut positioning block 761 is in the second position. In actual production, the connecting ring may swing when the nut is rotated after being placed in the nut. The nut positioning block in the nut positioning mechanism plays a stabilizing role, clamping and limiting the connecting ring, thus ensuring reliable rotation of the nut.

[0090] The present invention also includes:

[0091] The nut positioning mounting block 763 is located on the nut positioning drive component 762;

[0092] The nut positioning block 764 is hinged to the nut positioning drive 762, and the nut positioning block 761 is disposed on the nut positioning block 764.
