Description

Technical Field

[0001] This invention relates to the field of riveting technology, and in particular to a servo riveting device that integrates dust removal and detection. Background Technology

[0002] Riveting is a crucial processing technique in the assembly of automotive electronic and precision electrical components. The riveting accuracy, cleanliness, and dimensional consistency directly impact the assembly precision and reliability of the product, as exemplified by the riveting of automotive millimeter-wave radar antennas. Currently, traditional riveting equipment is mostly a single-station, simple tooling structure, commonly using hydraulic or pneumatic cylinders for downward pressure. Riveting is completed manually by holding the workpiece and using a foot pedal to control the equipment's start and stop. Riveting quality and appearance rely entirely on human experience and random inspection. This traditional processing method has extremely low automation, significant variations in human operation, resulting in poor product consistency and low production efficiency. Furthermore, close-range manual handling of the workpiece poses significant safety hazards, making it difficult to meet the requirements of high-volume, high-consistency, and high-reliability production of automotive electronic components.

[0003] Furthermore, existing traditional riveting equipment generally lacks a comprehensive dust removal and cleanroom protection system. Most equipment only has a simple air blowing structure, or even no dust removal mechanism at all. The riveting process generates a large amount of fine metal dust and metal debris, which easily adheres to the workpiece surface, the root of the rivet head, and the gaps between components. Traditional single air blowing dust removal methods not only fail to clean the workpiece surface thoroughly but also easily cause secondary floating and adhesion of dust, resulting in secondary contamination of the workpiece. Moreover, single vacuum adsorption dust removal methods cannot effectively remove residual debris from dead corners, resulting in limited dust coverage and incomplete dust removal. Residual conductive metal debris can easily cause short circuits and malfunctions in electronic products, significantly increasing the product defect rate. Simultaneously, traditional equipment lacks a corresponding dust and debris residue detection mechanism, making automated re-inspection of dust removal effectiveness impossible. Residual defects cannot be identified and screened in advance, leading to high risks in product quality control.

[0004] Meanwhile, traditional riveting structures driven by hydraulic cylinders and pneumatic booster cylinders cannot achieve precise closed-loop control of riveting pressure and downward stroke. The parameters fluctuate greatly during the riveting process, which further leads to poor consistency in rivet head height and outer diameter contour dimensions, resulting in low product processing accuracy. Moreover, the riveting, dust removal, and dimensional inspection processes of traditional equipment are fragmented, with each process relying on manual transfer and inspection. This not only results in low inspection efficiency and large human error, but also makes it difficult to trace processing data, hindering the achievement of full-process quality control and resulting in a low overall level of automation. Summary of the Invention

[0005] The purpose of this invention is to provide a servo riveting device that integrates dust removal and detection, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a servo riveting device integrating dust removal and detection, comprising a frame, a support on the frame, a riveting mechanism and a dust removal and detection mechanism mounted on the support, a clamp transfer assembly below the support, and a carrier assembly on the clamp transfer assembly;

[0007] The dust removal detection mechanism includes a second linear module arranged horizontally on the left and right sides. The second linear module is connected to a third sliding plate. The third sliding plate is connected to a detection structure and a dust removal structure.

[0008] The dust removal structure includes a support plate connected to a third sliding plate. The support plate is equipped with a vertically arranged sliding cylinder. The sliding cylinder is connected to a pneumatic conveyor. A fume hood is located below the pneumatic conveyor. A flexible hose is connected above the pneumatic conveyor. A dust collection hood is connected to the upper end of the flexible hose. The opening of the dust collection hood is downward. A rotary nozzle assembly that can automatically rotate and blow air is provided inside the fume hood.

[0009] Further optimization includes a windshield assembly containing an upper and lower air guide tube inside the windshield. The lower end of the air guide tube is connected to a rotatable joint. The windshield has a cylindrical structure that is smaller at the top and larger at the bottom. The rotatable joint has a cylindrical structure with multiple nozzles evenly spaced along its circumference on its side. The upper end of the air guide tube is connected to an air pipe connector, which is connected to an air source.

[0010] Further optimization involves having three nozzles, each with multiple downward-sloping air holes. Simultaneous airflow from all three nozzles can drive the rotary joint to rotate.

[0011] Further optimization includes the addition of an ion nozzle on the pallet and an integrated dust collection bag inside the dust collection hood.

[0012] Further optimization involves a detection structure comprising a 2D camera mounted on a third sliding plate, a light source positioned below the 2D camera, a first barcode scanner positioned to the side of the light source, and a rotatable adjustment plate positioned to the side of the 2D camera, on which a 3D camera is mounted.

[0013] In a further optimization, the riveting mechanism includes a first linear module arranged horizontally from left to right, a first slide plate mounted on the first linear module, a back plate mounted on the first slide plate, an electric cylinder mounted on the back plate, and a second slide plate that can slide up and down connected below the electric cylinder, on which a riveting machine is mounted.

[0014] Further optimization involves the fixture transfer assembly comprising two third linear modules arranged side-by-side, with each third linear module having a fourth sliding plate.

[0015] Further optimization involves two carrier components, each mounted on a fourth sliding plate. Each carrier component includes a base plate on which a carrier is mounted. A rotary clamping cylinder is located on each of the left and right sides of the carrier, and each rotary clamping cylinder is connected to a clamping arm.

[0016] Further optimization involves providing two barcode scanning and binding components on the left and right sides of the fixture transfer assembly on the frame. Each barcode scanning and binding component includes a barcode scanning platform, with a second barcode scanner located above and below the barcode scanning platform, and a sensor located below the barcode scanning platform.

[0017] Further optimization includes a manual barcode scanner and a conveyor belt system positioned on the left and right sides of the front of the rack.

[0018] Beneficial effects: The servo riveting device of the present invention, which integrates dust removal and detection, realizes product riveting through the setting of the riveting mechanism; through the setting of the dust removal and detection mechanism, it realizes rotation, multi-angle blowing and vacuum dust collection of the riveting position of the product, realizing thorough cleaning and dust removal of the product riveting station without dead corners, ensuring product cleanliness, and then performs 2D and 3D detection on the product to detect whether there are debris and dust particles at the riveting position, as well as to detect the height, radial and contour dimensions of the rivet head; through the clamping and transfer components and the carrier components, it realizes the clamping and precise transport of the product, and the electric cylinder drive of the riveting mechanism realizes the closed-loop precise control of riveting pressure and displacement, realizing high-precision riveting of the product, high riveting force and stroke accuracy, and high product riveting consistency;

[0019] The rotating nozzle assembly enables 360° rotating airflow, which, combined with the pneumatic conveyor and vacuum suction hood, forms a tornado-like dust removal structure. This achieves comprehensive removal of debris and dust after riveting, overcoming the drawbacks of traditional single air blowing and single vacuum dust removal. It can clean metal debris and dust from the root of the rivet head, corners, and other dead corners, preventing secondary pollution caused by floating debris and dust. With the addition of 2D camera visual inspection, it can accurately determine the residue of debris and dust, completely solving the potential for product short circuits and failures caused by metal debris and dust residue.

[0020] By using a 3D camera to automatically measure key dimensions after riveting and by using a barcode scanner to bind the product, the problems of low efficiency, large errors, and lack of traceability in traditional manual inspection can be solved. The dual conveyor line structure formed by two third linear modules enables alternating riveting, dust removal, and inspection of products, which greatly improves the efficiency of riveting operations and the riveting yield of products. This solves the problems of slow cycle time and low yield of traditional manual operation. At the same time, the automatic riveting operation is highly safe. Attached Figure Description

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0033] like Figure 1-5As shown, this application discloses a servo riveting device that integrates dust removal and detection, including a frame 1, a support 2 on the frame 1, a riveting mechanism 3 and a dust removal and detection mechanism 4 installed on the support 2, a clamp transfer assembly 5 below the support 2, and a carrier assembly 6 on the clamp transfer assembly 5.

[0034] The dust removal detection mechanism 4 includes a second linear module 41 arranged horizontally on the left and right sides. The second linear module 41 is connected to a third sliding plate 42. The third sliding plate 42 is connected to a detection structure 43 and a dust removal structure 44.

[0035] The dust removal structure 44 includes a support plate 441 connected to the third sliding plate 42. The support plate 441 is equipped with a vertically arranged sliding cylinder 442. The sliding cylinder 442 is connected to a pneumatic conveyor 443. A fume hood 444 is provided below the pneumatic conveyor 443. A hose 445 is connected above the pneumatic conveyor 443. A dust collection hood 446 is connected to the upper end of the hose 445. The opening of the dust collection hood 446 is downward. A rotary nozzle assembly 447 that can automatically rotate and blow air is provided inside the fume hood 444.

[0036] In this application, the servo riveting device is used for riveting operations on millimeter-wave radar products, realizing automated riveting, dust removal and inspection, which can improve riveting accuracy, clean the product after riveting, prevent secondary pollution of the product, and achieve high product inspection accuracy. Specifically, the servo riveting device includes a frame 1, a support 2, a riveting mechanism 3, a dust removal and detection mechanism 4, a fixture transfer assembly 5, and a carrier assembly 6. The frame 1 houses the various mechanisms, components, equipment control system, power supply system, and other devices. The support 2 is used to mount the riveting mechanism 3 and the dust removal and detection mechanism 4. The fixture transfer assembly 5 drives the carrier assembly 6 to move back and forth, loading products onto the carrier assembly 6 and moving it to the riveting station of the riveting mechanism 3, the dust removal and detection station of the dust removal and detection mechanism 4, and the product loading and unloading stations. Through the cooperation of the riveting mechanism 3, the dust removal and detection mechanism 4, the fixture transfer assembly 5, and the carrier assembly 6, automatic riveting, dust removal, and detection of products are achieved, greatly improving riveting efficiency and ensuring high consistency in product riveting.

[0037] In this application, the dust removal and inspection mechanism 4 includes a second linear module 41, a third sliding plate 42, a detection structure 43, and a dust removal structure 44. The second linear module 41 drives the third sliding plate 42 to move left and right, thereby moving the detection structure 43 and the dust removal structure 44. It can automatically move to the top of the product loaded on the carrier assembly 6 to automatically remove dust and inspect the product. The detection structure 43 can detect whether there are residual debris on the product, the height of the rivet head after riveting, and the radial and contour dimensions. The dust removal structure 44 can clean the riveted product, thoroughly removing debris from the product surface to avoid the potential for short circuits or product failure due to metal debris or dust residue.

[0038] In this application, the dust removal structure 44 includes a pallet 441, a sliding cylinder 442, a pneumatic conveyor 443, an exhaust hood 444, a hose 445, a dust collection hood 446, and a rotary nozzle assembly 447. The pallet is connected to the third sliding plate 42. While the second linear module 41 moves the third sliding plate 42 left and right, it can also move the pallet 441 and other dust removal structures 44 connected to the pallet 441 synchronously, achieving precise dust removal from the riveted product. The sliding cylinder 442 is used to drive the pneumatic conveyor... The conveyor 443 and the exhaust hood 444 rise and fall synchronously, allowing the exhaust hood 444 to cover the carrier assembly 6, forming a surrounding dust collection space for the riveting area of ​​the product. The exhaust hood 444, under the action of the pneumatic conveyor 443, creates negative pressure suction, forming a vacuum dust removal structure. This allows it to absorb debris and dust generated during riveting into the exhaust hood 444, and then, with the help of the high-speed airflow generated by the pneumatic conveyor 443, deliver it through the hose 445 into the dust collection hood 446 for collecting the collected debris and dust. The hose 445 connects the pneumatic conveyor 443 and the dust collection hood 446, which collects the debris absorbed by the pneumatic conveyor 443. A rotating nozzle assembly 447 is located inside the exhaust hood 444 and automatically rotates to blow air. The generated airflow blows away debris and dust adhering to the product surface, making it easier for the negative pressure within the exhaust hood 444 to absorb and remove it, thus improving the cleanliness of the product. The rotating air nozzle assembly 447 blows air from multiple angles, and the vacuum adsorption of the pneumatic conveyor forms a tornado-like dust removal structure, blowing up and sucking away the debris and dust generated during riveting. The multi-angle rotating airflow can create a thorough airflow to the riveting head, blowing away debris and dust from multiple angles, effectively preventing debris and dust from adhering to the product surface and failing to be sucked up, avoiding secondary pollution caused by floating dust, and completely solving the problem of short circuits and failures caused by debris and dust residue on the product surface.

[0039] In one embodiment of this application, the rotary nozzle assembly 447 includes a windshield 4471, and an air guide pipe 4472 arranged vertically inside the windshield 4471. The lower end of the air guide pipe 4472 is connected to a rotatable rotating joint 4473. The windshield 4471 has a cylindrical structure that is smaller at the top and larger at the bottom. The rotating joint 4473 has a cylindrical structure, and a plurality of nozzles 4474 are evenly spaced along its circumference on its side. The upper end of the air guide pipe 4472 is connected to an air pipe connector 4475, and the air pipe connector 4475 is connected to an air source.

[0040] In this embodiment, the rotary nozzle assembly 447 includes a wind deflector 4471, an air guide pipe 4472, a rotating joint 4473, a nozzle 4474, and an air pipe connector 4475. The wind deflector 4471 primarily isolates the nozzle 4474 from the exhaust hood 444, ensuring that the air generated by the nozzle 4474 is directed towards the product below, rather than being sucked away by the negative pressure within the exhaust hood 444, thus rendering the blowing ineffective. The air guide pipe 4472 connects the rotating joint 4473 and the air pipe connector 4475, ensuring that the air from the air pipe connector 4475 can enter the nozzle 4474 through the air guide pipe 4472. The connector 4473 can rotate relative to the air duct 4472. That is, when multiple nozzles 4474 blow out downward-sloping air, the downward-sloping airflow will generate a reaction force. The reaction force forms a torque around the air duct 4472. By rotating the connector 4473 relative to the air duct 4472, the connector 4473 can rotate, thus achieving relative rotation of the connector 4473. That is, both the nozzles 4474 and the connector 4473 rotate around the air duct 4472, forming a rotating, multi-angle blowing, which can ensure that the debris and dust on the product surface are blown up and floated. The floating debris and dust can be easily sucked away by the negative pressure suction in the exhaust hood 444.

[0041] In this embodiment, the windshield 4471 has a cylindrical structure that is smaller at the top and larger at the bottom. This is to accommodate the structure formed by the air guide pipe 4472, the rotary joint 4473, and the nozzle 4474, while also protecting these components. The rotary joint 4473 has a cylindrical structure to ensure air can be guided and to rotate smoothly relative to the air guide pipe 4472. The other end of the air pipe connector 4475 extends out of the side wall of the pneumatic conveyor 443, facilitating connection to an air source to provide compressed gas to the nozzle 4474.

[0042] Based on the above implementation, further, there are three nozzles 4474, each nozzle 4474 having multiple downward-sloping air holes 44741. Simultaneous airflow from all three nozzles 4474's air holes 44741 drives the rotary joint 4473 to rotate. That is, the angle between any two adjacent nozzles 4474 is 120°, forming a statically balanced structure. Even if the airflow from a single nozzle 4474 deviates, the overall radial force can still cancel each other out, ensuring uniform force distribution on the rotary joint 4473, smooth rotation, minimal vibration, and high long-term reliability. The three nozzles 4474 surround the riveting position of the product from three directions, ensuring thorough cleaning without blind spots, creating a comprehensive, all-around disturbance to the rivet head, and blowing away stubborn debris and dust for subsequent vacuum cleaning. The multiple air holes 44741 on each nozzle 4474 ensure sufficient airflow and blowing range. The tangential torque generated by the three nozzles 4474 is superimposed in the same direction, providing sufficient driving force to stably drive the rotary joint 4473 and the three nozzles 4474 to rotate as a whole.

[0043] Based on the above embodiments, the pallet 441 is further provided with an ion nozzle 448, which is connected to the air pipe connector of the rotary nozzle assembly 447. This ion nozzle generates positive and negative ions, which, together with compressed air, are blown towards the product. This eliminates static electricity and blows away debris and dust adsorbed by static electricity, further improving the blowing effect and ensuring the dust removal effect of the dust removal structure 44. The dust collection hood 446 integrates a dust collection bag, which can be used to filter and adsorb the collected debris and dust, achieving solid-gas separation; it also facilitates centralized cleaning of dust and debris.

[0044] In another embodiment of this application, the detection structure 43 includes a 2D camera 431 mounted on a third sliding plate 42. A light source 432 is provided below the 2D camera 431. A first barcode scanner 433 is provided on the side of the light source 432. A rotatable adjustment fixing plate 434 is provided on the side of the 2D camera 431. A 3D camera 435 is mounted on the adjustment fixing plate 434.

[0045] In this embodiment, the detection structure 43 includes a 2D camera 431, a light source 432, a first barcode scanner 433, an adjustment and fixing plate 434, and a 3D camera 435. The 2D camera 431 is used to detect debris and dust particles on the product surface to determine if any debris or dust remains. The light source 432 provides light to the 2D camera 431, eliminating ambient light interference, highlighting the rivet head contour features, and improving detection accuracy. The first barcode scanner 433 binds the detection and measurement results of the 2D camera 431 and the 3D camera 435 to the corresponding QR code on the product, and then uploads them to the MES system of the servo riveting device. The adjustment and fixing plate 434 adjusts the installation angle of the 3D camera 435 to ensure accurate measurement of the product. The 3D camera 435 can measure the rivet head height, rivet head outer diameter, and rivet head contour to determine whether the riveting quality of the product is qualified.

[0046] In another embodiment of this application, the riveting mechanism 3 includes a first linear module 31 arranged horizontally from left to right, a first slide plate 32 is mounted on the first linear module 31, a back plate 33 is mounted on the first slide plate 32, an electric cylinder 34 is provided on the back plate 33, a second slide plate 35 that can slide up and down is connected below the electric cylinder 34, and a riveting machine 36 is mounted on the second slide plate 35.

[0047] In this embodiment, the riveting mechanism 3 includes a first linear module 31, a first slide plate 32, a back plate 33, an electric cylinder 34, a second slide plate 35, and a riveting machine 36. The first linear module 31 drives the first slide plate 32 and other structural components mounted on it to move synchronously left and right, facilitating the riveting of the first or more products conveyed on the fixture transfer assembly 5. The first slide plate 32 is connected to the first linear module 31 and slidably connected to the bracket 2 via a linear guide rail. The back plate 33 is positioned between the first slide plate 32, the electric cylinder 34, and the second slide plate 35, serving to reduce vibration and improve structural strength, minimizing the impact of the electric cylinder 34 and the riveting machine 36 on the first linear module 31 and the entire servo riveting device during operation, and reducing riveting and inspection defects caused by vibration. The electric cylinder 34 drives the second slide plate 35 to rise and fall, thereby driving the riveting machine 36 mounted on it to rise and fall, thus achieving product riveting. A linear guide rail is provided between the second slide plate 35 and the back plate 33 to ensure smooth and precise lifting of the back plate 33. Furthermore, the electric cylinder 34 offers higher control precision, a cleaner environment free of oil stains, convenient parameter adjustment, and stable operation. The riveting machine 36 is used to apply pressure to the product by rotating it, using rolling extrusion to cause plastic deformation at the end of the rivet, forming a rivet head, and thus securing the products together to complete the riveting operation.

[0048] In another embodiment of this application, the fixture transfer assembly 5 includes two third linear modules 51 arranged side by side, and each third linear module 51 is provided with a fourth sliding plate 52. The two third linear modules 51 form two conveyor lines, which can simultaneously drive the two fourth sliding plates 52 to move back and forth. The fourth sliding plates 52 are used for mounting the carrier assembly 6. The two carrier assemblies 6 can simultaneously carry two products, which facilitates the alternating riveting, dust removal and inspection of the two products, and can greatly improve the product riveting efficiency.

[0049] Based on the above embodiments, further, there are two carrier assemblies 6, each mounted on one of the two fourth sliding plates 52. Each carrier assembly 6 includes a base plate 61, on which a carrier 62 is mounted. A rotary clamping cylinder 63 is located on each of the left and right sides of the carrier 62, and each rotary clamping cylinder 63 is connected to a clamping arm 64. Specifically, the two carrier assemblies 6 are correspondingly mounted on the two fourth sliding plates 52 connected to the two third linear modules 51 of the clamping transfer assembly 5. The third linear modules 51 drive the carrier assemblies 6 to move back and forth, and each carrier assembly 6 is used for loading one product. The base plate 61 connects the carrier 62 to the fourth sliding plates 52 and also mounts the rotary clamping cylinders 63. The rotary clamping cylinders 63 can drive the clamping arms 64 connected to them to rotate and move up and down, facilitating product clamping during loading and product release after riveting operations.

[0050] In this embodiment, the end of the clamping arm is also equipped with an anti-static POM pressure head, which can protect the product surface from being crushed or scratched. The POM material pressure head is relatively soft, providing a cushioning effect when clamping the product, preventing indentations and ensuring the product doesn't shift during riveting. It also eliminates static electricity, reducing the adhesion of debris and dust to the riveting location. Furthermore, in the above embodiment, the structure of the rotary clamping cylinder 63 and the clamping arm 64 can be replaced by a lever cylinder structure.

[0051] Based on the above implementation method, the frame 1 is provided with two barcode scanning and binding components 7 respectively located on the left and right sides of the clamp transfer assembly 5. Each barcode scanning and binding component 7 includes a barcode scanning platform 71, with a second barcode scanner 72 located above and below the barcode scanning platform 71. A sensor 73 is also located below the barcode scanning platform 71. The two barcode scanning and binding components 7 correspond to the two conveyor lines formed by the two third linear modules 51, respectively, enabling barcode scanning of two products on the corresponding two conveyor lines. Specifically, the product is placed on the barcode scanning platform 71 manually or by a robotic arm, and then the two second barcode scanners 72 scan the QR code, barcode, etc., on the product to confirm the product work order model and riveting parameters match. The sensor 73 is used to confirm whether there is a product on the barcode scanning platform 71. When a product is confirmed, the second barcode scanner 72 automatically scans the barcode.

[0052] In another embodiment of this application, the front of the frame 1 is also equipped with a manual barcode scanner and a left-right conveyor belt 8. The manual barcode scanner is used for manual scanning and can be used for manual verification or as a replacement for the barcode binding component 7 when it malfunctions. The conveyor belt 8 is used for product conveying and loading, facilitating material handling. A cover is provided on the top of the frame 1 to protect the various mechanisms and components mounted on the frame 1 and to ensure that the products are riveted, dusted, and inspected under specific environmental conditions.

[0053] In this application, the working process of the servo riveting device is as follows:

[0054] Place the pre-assembled product into the equipment fixture and start the equipment with both hands. Place the product on the barcode scanner 71 of the barcode binding component 7 for barcode scanning to confirm that the product order model and riveting parameters match. Then place the product on the carrier 62 of the carrier component 6, and the rotary clamping cylinder 63 drives the clamping arm 64 to press the product. Next, the clamping transfer component 5 transports the product to the riveting station below the riveting mechanism 3. The riveting mechanism 3 starts automatic riveting, and the first linear module 31 moves the riveting machine 36 to directly above the riveting position. Then, the electric cylinder 34 drives the riveting machine 36 to move downward to start riveting the product. After riveting is completed, the clamping transfer component 5 moves the product to the dust removal position, and the dust removal structure 44 starts cleaning and rotating. The nozzle 4474 of the air nozzle assembly 447 begins to blow air onto the riveting head. The nozzle 4474 and the rotary joint 4473 begin to rotate, forming a rotating, dynamic, and dead-angle-free airflow. At the same time, the pneumatic conveyor 443 also operates synchronously, using the exhaust hood 44 to vacuum the riveting station of the product, removing debris and dust from the product surface. After cleaning, the clamp transfer assembly 5 moves the product to the underside of the detection structure 43, where the 2D camera 431 detects debris and dust particles, and the 3D camera 435 detects the height and size of the riveting head. After the detection is completed, the clamp transfer assembly 5 drives the carrier assembly 6 to retract to the pick-up and drop-off position and indicates OK or NG. Then, the product is placed into the corresponding area manually or by a robotic arm.
