When applied, aluminum alloys are typically spliced ​​together to form a new structural frame. The traditional method of connecting aluminum alloys involves drilling holes in one of the connecting aluminum alloys and then using bolts or other fasteners on the other aluminum alloy to connect the two together, or using two exposed connectors to fix the two aluminum alloys.

[0003] Patent document CN202020991853.7 discloses a connection structure for aluminum materials, including a first body, a second body, and a third body. The first body has a first connecting groove on its top and a second connecting groove on one side. A first fixing bolt is provided on one side of the first connecting groove, and a second fixing bolt is provided on the bottom side of the second connecting groove. The second body is located on top of the first body, and a first connecting strip matching the first connecting groove is provided at the bottom of the second body. A first fixing screw hole matching the first fixing bolt is provided at the bottom of one side of the first connecting strip.

[0050] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0051] Example 1

[0052] like Figure 1-24 As shown, a fastener assembly system for connecting an aluminum composite frame is disclosed. The fastener 6 comprises parts a61, b62, and c63. Part a61 includes an arc-shaped block 611, the cross-section of which has a threaded groove 612 and two slots 613. Part b62 includes a circular block 621, the height of which is the same as the height of the arc-shaped block 611, and a through hole 622 on its circumferential side. Part c63 is integrally formed of a threaded rod 631 and a nut 632 at its end. The end face of part 32 is provided with an internal hexagonal groove. One end of the threaded rod 631 passes through the through hole 622 of part b62 and is installed in the threaded groove 612 of part a61, thereby assembling the fastener 6. The structure of the aluminum material is an aluminum strip 7 with a square cross-section. Each of the four sides of the aluminum strip 7 is provided with a through groove 71 for part a61 to enter from its end. The through groove 71 is provided with a stop block 72 to limit the position of part a61 and a locking block 73 that matches the locking groove 613. Each of the four sides of the aluminum strip 7 is also provided with a round hole 74 to accommodate part b62.

[0053] The assembly system includes a screening mechanism 1 that is inclined and used to output parts a of the same specification, two sets of first conveying mechanisms 2 that are located below the screening mechanism 1 and used to convey parts a, a second conveying mechanism 3 that is arranged synchronously with the first conveying mechanism 2 and used to convey parts b, an assembly mechanism 4 that is arranged on the second conveying mechanism 3 and used to assemble fasteners 6, and a material support mechanism 5 that is located below the second conveying mechanism 3 and used to support aluminum materials for connection.

[0054] The screening mechanism 1 includes a vibrating plate 11, a height limiting component 12 disposed at the output end of the vibrating plate 11, a width limiting component 13 disposed at the output end of the height limiting component 12, and a sorting component 14 disposed at the output end of the width limiting component 13.

[0055] The assembly mechanism 4 includes a first assembly component 41 disposed on the second conveying mechanism 3 for assembling parts b and c, and a second assembly component 42 disposed on the second conveying mechanism 3 for fastener assembly completion.

[0056] It should be noted that the first conveying mechanism 2, the second conveying mechanism 3, the assembly mechanism 4, and the material support mechanism 5 are all divided into two groups and distributed on both sides of the screening mechanism 1. This embodiment only describes the part on one side of the screening mechanism 1.

[0057] In this embodiment, the screening mechanism 1 and the assembly mechanism 4 work together to automatically assemble fasteners and output them one by one, achieving a high degree of automation. Pre-assembling fasteners facilitates the assembly of the aluminum frame and reduces the assembly time. On the other hand, the assembled fasteners are automatically placed at the joints of the aluminum frame and automatically tightened to complete the assembly of the aluminum frame. The structure has good linkage, improving the assembly efficiency of the aluminum frame and enabling batch automatic assembly of aluminum frames, thus increasing the economic benefits for enterprises.

[0058] In detail, the screening mechanism 1 screens out parts a of the same specification and outputs them one by one to the first conveying mechanism 2. At the same time, the second conveying mechanism 3 carries parts b and runs synchronously with the first conveying mechanism 2. The first assembly component 41 first assembles parts c onto parts b, and the second assembly component 42 then assembles parts c and parts b onto parts a, completing the fastener assembly. Then, the two aluminum strips are placed end to end vertically connected on the support mechanism 5 by the existing robotic arm or manually. The fasteners fall into the connection of the two aluminum strips one by one, and finally the fasteners are automatically tightened, completing the assembly of the two aluminum strips.

[0059] Furthermore, such as Figure 8 and Figure 10-14 As shown, the height limiting component 12 includes a height limiting channel 121 inclinedly disposed at the output end of the vibratory feeder 11, a height limiting rod 122 disposed on the height limiting channel 121, and a return member 123 disposed above the height limiting rod 122 for retracting the excessively tall part a. The vibratory feeder 11 is driven by a vibration motor.

[0060] The return component 123 includes a rotating rod 1231 mounted on the height limiting rod 122 via an ear plate and a plurality of return heads 1232 mounted on the circumferential side of the rotating rod 1231. The rotating rod 1231 is driven by an existing drive motor.

[0061] The width limiting component 13 includes a width limiting channel 131 disposed at the output end of the height limiting channel 121, a rotary component 132 disposed at the connection between the height limiting channel 121 and the width limiting channel 131 and used to drive the ultra-wide part a to rotate, and a stop component 133 disposed at the output end of the width limiting channel 131 and used to temporarily store a part a.

[0062] The rotary component 132 includes a plurality of rotary wheels 1321 disposed at the output end of the height limiting channel 121, and the rotary wheels 1321 are driven by existing drive motors.

[0063] The material blocking component 133 includes a material blocking frame 1331 that is lifted and disposed at the output end of the width limiting channel 131. The material blocking frame 1331 is installed on the width limiting channel 131 by an elastic telescopic component.

[0064] The sorting assembly 14 includes a disc 141 disposed at the output end of the width-limiting channel 131, a mounting plate 143 rotatably disposed at the bottom of the disc 141 via a shaft 142, two sets of first hydraulic components 144 disposed on the mounting plate 143, a transfer component 145 disposed at the output end of the first hydraulic components 144 and used to transfer a single part a, and two sets of contouring channels 146 symmetrically disposed at the bottom of the disc 141 and adapted to the part a. The two sets of contouring channels 146 are respectively used to receive parts a with different orientations. The shaft 142 is driven by an existing drive motor.

[0065] The material transfer component 145 includes a material transfer frame 1451 disposed at the output end of the first hydraulic component 144 and adapted to the material stop frame 1331, and a side plate 1452 disposed inside the material transfer frame 1451 by an elastic telescopic component.

[0066] In this embodiment, by cooperating with the screening mechanism 1 and the first conveying mechanism 2, on the one hand, parts a of the same specification can be automatically screened out and output one by one to the first conveying mechanism 2, which facilitates the assembly of fasteners; on the other hand, the transfer frame 1451 of the transfer component 145 can make parts a move along the inner wall of the disc 141, so that parts a fall into the contour channel 146 in sequence, thereby facilitating the screening of parts a with different cross-sectional orientations and facilitating the output of parts a of the same specification.

[0067] In detail, part a is output to the height limiting component 12 via the vibratory feeder 11. When part a is upright, it is blocked by the height limiting bar 122. The rotating rod 1231 of the return component 123 rotates the return head 1232, causing the return head 1232 to push the upright part a back, removing it from the height limiting bar 122. Then, the flat part a enters the width limiting component 13. The rotating wheel 1321 of the rotating component 132 drives away the part a blocking the input end of the width limiting component 13, allowing part a with its cross-section facing both sides to enter the stop component 133. Then, the shaft 142 drives the rotating component 145 to move to the stop frame 1. After stopping at the position directly above 331, the first hydraulic component 144 drives the transfer component 145 to descend, causing the transfer frame 1451 to press down the stop frame 1331 and align with the bottom of the width limiting channel 131. Then, the shaft 142 drives the transfer component 145 to move again, causing the transfer frame 1451 to carry away the single part a on the width limiting channel 131, and causing part a to revolve along the inner wall of the disc 141. When part a passes the position of the two contour channels 146, it falls from one of the contour channels 146, thereby sorting out parts a with different cross-sectional orientations and outputting parts a of the same specification.

[0068] Furthermore, such as Figure 8-10 and Figure 17-18 As shown, the first conveying mechanism 2 includes a first conveying frame 21 located below the sorting component 14, two sets of first conveyor belts 22 arranged in opposite directions and synchronously on the first conveying frame 21 and located directly below the contouring channel 146, and several sets of first contouring grooves 23 formed on the first conveyor belts 22 and adapted to part a.

[0069] It should be noted that the distance from the bottom of the first contouring groove 23 to the lower end of the contouring channel 146 is equal to the height of part a. When the first contouring groove 23 passes directly below the contouring channel 146, a single part a falls into the first contouring groove 23. The part a just detaches from the lower end of the contouring channel 146, allowing the first contouring groove 23 to carry away the single part a. The first conveyor belt 22 supports the part a, preventing it from completely detaching from the lower end of the contouring channel 146. Therefore, the first conveyor belt 22 will not carry away the part a, allowing parts a to fall into the first contouring groove 23 sequentially, thus ensuring that parts a are discharged evenly in sequence.

[0070] In this embodiment, the first conveying mechanism 2 can receive parts a in sequence, so that parts a are discharged evenly in sequence, and can be conveyed forward to facilitate the assembly of fasteners.

[0071] In detail, when the first contouring groove 23 on the first conveyor belt 22 passes directly below the contouring channel 146, a single part a falls into the first contouring groove 23. The part a just detaches from the lower end of the contouring channel 146, so that the first contouring groove 23 can carry away the single part a.

[0072] Furthermore, such as Figure 15-16 and Figure 19 As shown, the second conveying mechanism 3 includes two sets of material drop cylinders 31 symmetrically arranged on the outer wall of the disc 141 via connecting rods and containing parts b of the same specification; a second conveying frame 32 horizontally arranged on the first conveying frame 21 and located below the material drop cylinders 31; a second conveying belt 33 arranged on the second conveying frame 32 and synchronously arranged with the first conveying belt 22; and several sets of second contour grooves 34 formed on the second conveying belt 33 and adapted to the parts b.

[0073] In this embodiment, the second conveying mechanism 3 can carry part b and move synchronously with part a on the first conveyor belt 22, so that the positions of part a and part b always correspond, which facilitates the assembly of fasteners.

[0074] In detail, when the second contour groove 34 on the second conveyor belt 33 passes directly below the material drop cylinder 31, a single part b falls into the second contour groove 34. The part b just detaches from the lower end of the material drop cylinder 31, so that the second contour groove 34 can carry away the single part b.

[0075] Furthermore, such as Figure 15-16 and Figure 19 As shown, the first assembly assembly 41 includes a feed cylinder 411 mounted on the second conveyor frame 32 via a bracket and containing part c; a push plate mounted on the bracket via a first elastic element 412 for pushing part c in the feed cylinder 411 forward; a surrounding plate 413 mounted on the second conveyor belt 33 for blocking part c from advancing; several sets of notches 414 formed on the surrounding plate 413 and corresponding to the positions of the second contoured groove 34; an adjusting wheel 415 rotatably mounted on the second conveyor frame 32 via a rotating shaft for adjusting the orientation of the through hole of part b; and a baffle 416 mounted on the first conveyor frame 21. The nut of part c slides and matches the inner wall of the feed cylinder 411. The width of the notch 414 is the same as the diameter of the nut of part c. The adjusting wheel 415 is driven by an existing drive motor.

[0076] It should be noted that the parts c inside the feed cylinder 411 are added manually in batches.

[0077] In this embodiment, the first assembly component 41 can automatically adjust the orientation of the through hole of part b, making it easier for part c to be assembled into the designated position of part b, which is beneficial to the assembly of the entire fastener. On the other hand, it can enable individual parts c and parts b to be assembled in a corresponding manner, with high assembly accuracy and fast speed.

[0078] In detail, the second conveyor belt 33 carries part b to the position of the feed cylinder 411 and then stops. Part c, driven by the first elastic element 412, passes through the corresponding notch 414, so that the threaded end of part c abuts against the circumferential side of part b. At the same time, the adjusting wheel 415 drives part b to rotate in the second contour groove 34, adjusting the orientation of the through hole of part b, so that the threaded end of part c can continue to pass through the through hole of part b and abut against the baffle 416. At this time, the nut of part c is exactly located in the notch 414 of the surrounding plate 413, thereby assembling part c into the designated position of part b. Then the second conveyor belt 33 continues to carry part b forward a designated distance. The surrounding plate 413 on the second conveyor belt 33 obstructs the output of part c in the feed cylinder 411 until the notch 414 of the surrounding plate 413 passes through the position of the feed cylinder 411 again, and the assembly work of the next part b and part c is carried out.

[0079] Furthermore, such as Figure 15-16 and Figure 20-21 As shown, the second assembly assembly 42 includes a third conveyor frame 421 mounted on the second conveyor frame 32 via a connecting rod, a third conveyor belt 422 mounted on the third conveyor frame 421 and synchronously mounted with the second conveyor belt 33, several sets of mounting blocks 423 mounted on the third conveyor belt 422, a slide rod 424 penetrating and slidably mounted on the mounting block 423, a first rotating head 425 mounted on one end of the slide rod 424 via an elastic telescopic member, a top block rotatably mounted on the other end of the slide rod 424, a limiting rail 426 mounted on the third conveyor frame 421 for driving the first rotating head 425 forward, a second elastic member 427 mounted between the top block and the mounting block 423 for resetting the first rotating head 425, a gear 428 rotatably mounted on the mounting block 423 for driving the first rotating head 425 to rotate, and a rack 429 mounted on the third conveyor frame 421 for driving the gear 428.

[0080] In this embodiment, the second assembly component 42 can automatically assemble part c onto part a, thus completing the fastener assembly.

[0081] In detail, the third conveyor belt 422 carries the first rotating head 425 and runs synchronously with the second conveyor belt 33. Driven by the limiting rail 426, the slide bar 424 carries the first rotating head 425 to the nut of part c in the corresponding notch 414. At the same time, the gear 428, driven by the rack 429, carries the first rotating head 425 to rotate, so that the first rotating head 425 matches the internal hexagonal groove of the nut and carries part c to rotate forward, so that the threaded end of part c is threaded into the threaded groove 612 of part a, thereby completing the overall assembly of the fastener.

[0082] Example 2

[0083] like Figure 8-9 , Figure 17-18 As shown in Figures 22-24, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0084] Furthermore, such as Figure 17-18 As shown, the material support mechanism 5 includes a material guiding component 51 disposed on the first conveyor frame 21 for guiding fasteners and a support component 52 disposed below the first conveyor frame 21.

[0085] The material guiding assembly 51 includes an arc-shaped guide plate 511 mounted on the first conveyor frame 21 via a connecting rod, a receiving plate 512 mounted on the output end of the arc-shaped guide plate 511, and a material leakage hole 513 opened on the receiving plate 512 and adapted to the fastener.

[0086] In this embodiment, the assembled fasteners are moved to a position below the first conveying mechanism 2 by the material guide component 51, and can fall at a fixed point at the connection of the aluminum material, so that the fasteners can be installed on the aluminum frame.

[0087] In detail, the assembled fasteners slide along the arc-shaped guide plate 511 to the material discharge hole 513 of the receiving plate 512, so that the fasteners fall into the connection of the aluminum material in sequence.

[0088] Furthermore, as shown in the figure Figure 17-18 As shown in Figures 22-24, the support assembly 52 includes an L-shaped frame 521 positioned below the first conveyor frame 21 for supporting the aluminum material for vertical connection of ends; a limiting plate 522 positioned on the L-shaped frame 521 for limiting the connection point of the aluminum material to be located directly below the material leakage hole 513; a second hydraulic component 523 positioned on the L-shaped frame 521; a stepper motor 524 positioned at the output end of the second hydraulic component 523; and a second rotating head 525 positioned at the output end of the stepper motor 524 for tightening fasteners at the connection point of the aluminum material.

[0089] In this embodiment, by cooperating with the material guide component 51 and the support component 52, the fasteners can be automatically installed on the aluminum frame and tightened to complete the assembly of the aluminum frame.

[0090] In detail, two aluminum strips are placed end-to-end on an L-shaped frame 521 using an existing robotic arm or manually. Fasteners fall from the material outlet 513 of the receiving plate 512 to the joint of the aluminum strips, causing part b of the fastener to fit into the round hole of the aluminum strip. Part a of the fastener falls from the through slot onto the stop block, making part b and part a on the same plane, ensuring the fastener is placed horizontally. The second hydraulic component 523 drives the second rotating head 525 to advance from the through slot to the nut of part c. The stepper motor 524 drives the second rotating head 525 to rotate and tighten part c. Since part a is limited by the stop block 72, it will not rotate on its own. Therefore, the threaded rod of part c forces part a to move, causing the slot of part a to engage with the locking block 73 in the through slot, thereby completing the assembly of the aluminum material. Because the slot of part a engages with the locking block 73 in the through slot, the fastener will not slide out of the aluminum strip, ensuring the firmness of the aluminum material assembly.

[0091] Work process:

[0092] Screening mechanism 1 screens out parts a of the same specification and outputs them one by one to the first conveying mechanism 2. At the same time, the second conveying mechanism 3 carries parts b and runs synchronously with the first conveying mechanism 2. The first assembly component 41 first assembles part c onto part b, and the second assembly component 42 then assembles parts c and part b onto part a, completing the fastener assembly. Then, the two aluminum strips are placed end to end vertically connected on the support mechanism 5 by the existing robotic arm or manually. The fasteners fall into the connection of the two aluminum strips one by one, and finally the fasteners are automatically tightened, completing the assembly of the two aluminum strips.
