Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention discloses a riveting nut conveying mechanism and its packaging machine.

[0025] Example 1: According to the appendix Figure 1-6 As shown, a rivet nut conveying mechanism includes: Support frame 1; Conveyor belt 2 is mounted on support frame 1 and is used to transport rivet nuts; Track mounting unit 3 is positioned above conveyor belt 2 and is used to sort defective products during the transmission process. Detection unit 4 is installed on the track mounting unit 3 and is used for multi-directional detection of the rivet nut. The switch drive unit 5 is mounted on the track mounting unit 3 and is used to control the opening and closing of the switch. The shielding unit 6 is located on one side of the track mounting unit 3 and is used to block the riveting nut. Weighing unit 7 is located on one side of shielding unit 6 and is used to detect the weight of disposable packaging. The material pushing unit 8 is located on one side above the weighing unit 7 and is used for unloading. The first processor is connected to the detection unit 4 and the turnout drive unit 5; The second processor is connected to the shielding unit 6, the weighing unit 7, and the pushing unit 8.

[0026] Furthermore, a loading platform 11 is provided at one end of the support frame 1, and the loading platform 11 is located at one end of the conveyor belt 2; the rivet nut is placed on the conveyor belt 2 through the loading platform 11, and the conveyor belt 2 runs on the support frame 1 to transport the rivet nut to the track mounting unit 3.

[0027] The other end of the support frame 1 has a discharge port 12; Waste discharge pipes 13 are provided on both sides of the middle position of the support frame 1; The other end of the support frame 1 is fixedly connected to a baffle 14.

[0028] Furthermore, the track mounting unit 3 includes: Track assembly 31; Connecting block 32, the bottom end of which is fixedly connected to track assembly 31; The horizontal block 33 is fixedly connected to the top of the connecting block 32, and the horizontal block 33 is mounted on the support frame 1.

[0029] Furthermore, the track assembly 31 includes: The conveying channel 311 is T-shaped and is used to ensure that the rivet nuts are transported in a vertical position. The rivet nuts are in a vertical position during transportation, which is beneficial for inspection and sorting. The detection channel 312 is fixedly connected to one side of the material conveying channel 311; The defective product channel 313 is fixedly connected to one side of the detection channel 312 and is connected to the waste discharge pipe 13. A branch channel partition 314 is rotatably connected at one end to the defective product channel 313. The branch channel partition 314 is connected to the branch channel drive unit 5, which drives the branch channel partition 314 to rotate. By using the branch channel drive unit 5 and the branch channel partition 314 in the track assembly 31, defective products can be automatically sorted into the defective product channel 313 according to the detection results, thereby improving production efficiency and reducing labor costs.

[0030] The inlet channel 315 is fixedly connected to one side of the defective product channel 313, and one end of the inlet channel 315 is located at the branch channel partition 314.

[0031] With its compact and rationally laid-out structure, including material conveying channel 311, inspection channel 312, and defective product channel 313, the conveying mechanism ensures smooth conveying and effective inspection and sorting of rivet nuts while maximizing space savings. This significantly reduces the footprint of the entire conveying mechanism and integrates multiple complex functions within a limited space.

[0032] The track installation unit 3 not only rationally plans the positions of each channel in the horizontal direction, but also adopts a layered design in the vertical direction, setting channels with different functions at different height levels. Through reasonable guidance and conveying devices, it realizes the smooth flow of materials at different levels. This three-dimensional layout greatly improves space utilization and achieves the integration of more functions on a limited floor space.

[0033] The compact layout of the track-mounted unit 2 makes it ideal for use in production environments with limited space. Its small footprint allows for flexible placement within existing production workshops without the need for large-scale renovations or expansions. Furthermore, its compact layout provides better mobility and adjustability. During production, companies can rearrange or adjust the equipment according to changes in production tasks. The conveying mechanism, due to its compact structure and relatively light weight, can be easily moved and reinstalled, quickly adapting to different production needs.

[0034] Furthermore, the detection unit 4 includes: Camera detection head 41 is positioned above detection channel 312 and is connected to the first processor. Camera detection head 41 is used to capture images of rivet nuts. The clamping and rotating assembly 42 is positioned directly below the camera inspection head 41. By setting up the inspection unit 4, including the camera inspection head 41 and the clamping and rotating assembly 42, multi-directional inspection of the riveted nut can be performed, effectively improving the accuracy and comprehensiveness of the inspection, reducing missed and false detections, and ensuring product quality.

[0035] Furthermore, the clamping rotation assembly 42 includes: Rotary seat 421 is rotatably connected within detection channel 312; Clamping cylinder 422 is mounted on rotary seat 421; Clamping block 423, the clamping block 423 is configured in two sets, and both sets of clamping blocks 423 are mounted on clamping cylinder 422; A geared motor 424 is connected to a rotating base 421 at its output end. The riveting nut enters the conveying channel 311 of the track assembly 31 from the loading platform 11. During conveying, the camera detection head 41 captures images of the riveting nut and transmits the image information to the first processor. Simultaneously, the clamping cylinder 422 in the clamping rotating assembly 42 drives the clamping block 423 to clamp the riveting nut, and the geared motor 424 drives the rotating base 421 to rotate, causing the riveting nut to rotate so that the camera detection head 41 can perform multi-directional detection, ensuring accurate and efficient detection of various types of riveting nuts.

[0036] The first processor determines whether the riveting nut is a qualified product based on the inspection results. If it is a defective product, it controls the switch drive unit 5 to drive the switch partition 314 to rotate, guiding the defective product to the defective product channel 313. Qualified products are transported through the merging channel 315 into the main channel 316 and then through the buffer channel 317 to the subsequent process. The first processor, the inspection unit 4, and the switch drive unit 5 are all connected. Through the inspection unit 4, the riveting nut can be inspected from multiple angles, effectively improving the accuracy and comprehensiveness of the inspection, reducing missed and false inspections, and ensuring product quality. The inspection unit 4 controls the switch drive unit 5 to drive the switch partition 314 to rotate through the processing and analysis of the first processor. By suspending the track assembly 31 above the conveyor belt 2, it automatically sorts defective products to the defective product channel 313 based on the inspection results, improving production efficiency and reducing labor costs.

[0037] Example 2: According to the appendix Figure 1-6 As shown, a rivet nut conveying mechanism includes: Support frame 1; Conveyor belt 2 is mounted on support frame 1 and is used to transport rivet nuts; Track mounting unit 3 is positioned above conveyor belt 2 and is used to sort defective products during the transmission process. Detection unit 4 is installed on the track mounting unit 3 and is used for multi-directional detection of the rivet nut. The switch drive unit 5 is mounted on the track mounting unit 3 and is used to control the opening and closing of the switch. The shielding unit 6 is located on one side of the track mounting unit 3 and is used to block the riveting nut. Weighing unit 7 is located on one side of shielding unit 6 and is used to detect the weight of disposable packaging. The material pushing unit 8 is located on one side above the weighing unit 7 and is used for unloading. The first processor is connected to the detection unit 4 and the turnout drive unit 5; The second processor is connected to the shielding unit 6, the weighing unit 7, and the pushing unit 8.

[0038] Furthermore, the occlusion unit 6 includes: Fixed base 61, fixedly connected to support frame 1; The first hydraulic cylinder 62 is mounted on the fixed base 61 and is connected to the second processor. The lifting plate 63 is fixedly connected to the output end of the first hydraulic cylinder 62.

[0039] Furthermore, the weighing unit 7 includes: Weighing platform 71 is located at the other end of conveyor belt 2. Weight sensor 72 is located below weighing platform 71. Weight sensor 72 is used to detect the weight of the riveted nuts on weighing platform 71. Weight sensor 72 is connected to the second processor.

[0040] Furthermore, the feeding unit 8 includes: The second hydraulic cylinder 81 is located on one side of the support frame 1 and is connected to the second processor. Push plate 82 is fixedly connected to the output end of the second hydraulic cylinder 81 and is located directly opposite the discharge port 12. Rivet nuts enter the weighing platform 71 through the buffer channel 317. The weight sensor 72 detects the weight of the rivet nuts on the weighing platform 71 and transmits the weight information to the second processor. As more rivet nuts are added to the weighing platform 71, until the weight reaches a set value, the second processor controls the first hydraulic cylinder 62 to drive the lifting plate 63 to descend, and then controls the second hydraulic cylinder 81 to drive the push plate 82 forward, pushing the qualified rivet nuts on the weighing platform 71 into the discharge port 12 in one go. After unloading, the push plate 82 and the lifting plate 63 reset, and the rivet nuts in the buffer channel 317 continue to be transported to the weighing platform 71.

[0041] The second processor is connected to the shielding unit 6, the weighing unit 7, and the pushing unit 8. The riveting nuts are transported to the weighing unit 7 via the conveyor belt 2. The weighing unit 7 can accurately detect the weight of the riveting nuts in the one-time packaging, ensuring the accuracy of product packaging and meeting the weight requirements of different customers. The second processor controls the shielding unit 6 to close by receiving the electrical signal from the weight sensor 72, and then controls the pushing unit 8 to push the riveting nuts on the weighing unit 7 into the packaging machine in one go, which not only improves the accuracy of packaging, but also improves packaging efficiency.

[0042] By employing a dual-processor architecture with coordinated control of the first and second processors, the control of the entire conveying mechanism and packaging machine becomes more efficient and stable. The first processor is primarily responsible for connecting with the detection unit 4 and the switch drive unit 5, processing detection data in real time, and controlling the sorting of defective products. The second processor focuses on connecting with the shielding unit 6, the weighing unit 7, and the pushing unit 8, precisely controlling the weighing and packaging processes. The two processors interact and collaborate via a high-speed communication interface, enabling parallel processing and efficient cooperation among the functional modules.

The packaging machine unit 9 includes: Equipment cabinet 91; An extension seat 92 is fixedly connected to the equipment cabinet 91, and an extrusion and hot cutting assembly is installed inside the extension seat 92. Sleeve 93 is positioned above the extension seat 92; The packaging bag conveying assembly 94 is positioned above the sleeve 93. After passing inspection and weighing, the rivet nuts enter the packaging machine unit 9. The packaging bag conveying assembly 94 conveys the packaging bag to the sleeve 93. The extrusion and heat-cutting assembly inside the extension seat 92 inserts the rivet nuts into the packaging bag and performs heat-cutting and sealing, completing the packaging process.
