Therefore, the above terms cannot be understood as limiting the present invention.

[0038] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0039] refer to Figures 1 to 17 An automatic riveting device according to a preferred embodiment of the present invention will be described in detail below, wherein the automatic riveting device includes a feeding mechanism 10, a suction mechanism 20, a placement mechanism 30, a clamping mechanism 40 and a riveting mechanism 50.

[0040] Specifically, the feeding mechanism 10 includes a material discharging component 11. The material discharging component 11 includes at least one material discharging plate 111. A plurality of connecting plates 910 are placed on the material discharging plate 111 in a stacked manner.

[0041] The suction mechanism 20 includes a material suction moving unit 21 and a plurality of material suction members 22. The material suction moving unit 21 is located near the material discharge member 11. The material suction members 22 are arranged on the material suction moving unit 21 so as to press against and absorb one of the connecting plates 910 placed on the material discharge plate 111. The connecting plate 910 sucked by the material suction moving unit 21 is moved to a predetermined position by the material suction moving unit 21. In other words, after the material suction member 22 absorbs the connecting plate 910, the material suction moving unit 21 can drive the material suction member 22 to move the sucked connecting plate 910 to a predetermined position.

[0042] The placement mechanism 30 includes a placement plate 31. The placement plate 31 is positioned below the connecting plate 910, which has been sucked and moved to a predetermined position by the material suction member 22. The placement plate 31 forms a plate placement space 3101 adapted for the connecting plate 910. When the material suction and movement unit 21 drives the material suction member 22 to move the sucked connecting plate 910 to a predetermined position, the connecting plate 910 can be placed in the plate placement space 3101 for subsequent operations.

[0043] The clamping and shifting mechanism 40 includes a clamping and shifting drive unit 41 and a clamping member 42. The clamping member 42 is mounted on the clamping and shifting drive unit 41 so that it can move closer to or further away from the placement plate 31. The clamping member 42 has a pair of clamping fingers 421 that can move relative to and away from each other. The pair of clamping fingers 421 is used to clamp the connecting plate 910 from the plate placement space 3101. After the pair of clamping fingers 421 move a predetermined distance away from the placement plate 31, the connecting plate 910 is released for subsequent operation.

[0044] As an example, when the clamping member 42 is driven by the material clamping and shifting driving unit 41 and approaches the connecting plate 910 in the plate placement space 3101, the connecting plate 910 in the plate placement space 3101 can be clamped by the relative movement of a pair of clamping fingers 421, and after the material clamping and shifting driving unit 41 drives the connecting plate 910 clamped by the pair of clamping fingers 421 to move away from the placement plate 31, the connecting plate 910 can be released by moving the pair of clamping fingers 421 away from each other to perform subsequent operations on the connecting plate 910.

[0045] The rivet mechanism 50 is used to rivet a rivet nut 920 in each connecting hole 9101 of the connecting plate 910. The rivet mechanism 50 includes a rivet assembly 51, a rivet support platform 52, and a rivet flip 53. The rivet support platform 52 is located on the path where the pair of clamping fingers 421 clamp the connecting plate 910 and are driven by the clamping and shifting driving unit 41 to move. The rivet support platform 52 forms a rivet support space 5201 for placing the connecting plate 910 clamped by the pair of clamping fingers 421. The rivet flip 53 is arranged on the rivet support platform 52, and the rivet flip 53 has a rivet flip end 531 that protrudes toward the rivet support space 5201, and the rivet flip end 531 corresponds to the connecting hole 9101 of the connecting plate 910. The rivet assembly 51 includes a rivet driving member 511 and a rivet flip 512. The press riveting driver 511 is located near the press riveting support platform 52 and faces the flip riveting end 531. The press riveting member 512 is disposed on the press riveting driver 511 in a manner that it can move toward the flip riveting end 531. When the press riveting member 512 moves toward the flip riveting end 531, the rivet nut 920 located between the press riveting member 512 and the flip riveting end 531 is brought toward the flip riveting end 531. At the same time, a flip riveting portion 921 of the rivet nut 920 passes through the connecting hole 9101 corresponding to the flip riveting end 531 and abuts against the flip riveting end 531. In the process of the press riveting member 512 continuously pushing the rivet nut 920, the rivet nut 920 is press-riveted to the connecting plate 910 in a radial flip riveting manner by the flip riveting portion 921.

[0046] That is to say, on the path where the rivet component 512 is moved by the rivet driving component 511, the rivet nut 920, the riveted portion 921 of the rivet nut 920, the connecting hole 9101 corresponding to the riveted end 531, and the riveted end 531 are sequentially arranged. The outer diameter of the rivet nut 920 is larger than the inner diameter of the connecting hole 9101, the outer diameter of the riveted portion 921 is adapted to the inner diameter of the connecting hole 9101, and the rivet nut 920, the riveted portion 921, the connecting hole 9101, and the riveted end 531 are coaxial.

[0047] As an example, the riveted portion 921 of the rivet nut 920 is directed toward the connecting hole 9101 corresponding to the riveted end 531, and after being driven by the rivet component 512 and passing through the connecting hole 9101 corresponding to the riveted end 531, the inner wall of the riveted portion 921 will be pressed by the riveted end 531. In the process of the rivet nut 920 being continuously pushed by the rivet component 512, the riveted portion 921 will be guided by the riveted end 531 and folded along the radial direction of the riveted end 531 to be riveted into the connecting plate 910, thereby riveting the rivet nut 920 as a whole to the connecting hole 9101 corresponding to the riveted end 531.

[0048] Furthermore, after one rivet nut 920 is riveted integrally to the connection hole 9101 corresponding to the riveting end 531, the connecting plate 910 can be clamped again by the pair of clamping fingers 421. Driven by the clamping and shifting driving unit 41, the connecting plate 910 clamped by the pair of clamping fingers 421 is placed in the riveting support space 5201 of the riveting support platform 52 in such a manner that another connection hole 9101 corresponds to the riveting end 531, so as to continue to rivet another rivet nut 920 to another connection hole 9101 corresponding to the riveting end 531. In this way, the rivet nut 920 is riveted in each connection hole 9101 of the connecting plate 910.

[0049] Preferably, the connecting line of each connecting hole 9101 of the connecting plate 910 is parallel to the direction in which the clamping member 42 is moved by the material clamping and shifting driving unit 41, so as to ensure that the material clamping and shifting driving unit 41 can be driven by a pair of the clamping fingers 421 of the clamping member 42 to place each connecting hole 9101 in the rivet support space 5201 in a manner such that the connecting hole 9101 corresponds to the rivet end 531.

[0050] Preferably, the riveting driver 511 is implemented to include a gas-liquid booster cylinder.

[0051] It is worth mentioning that since multiple connecting plates 910 are placed in a stacked manner on the discharge plate 111, the consistency of the suction member 22 in sucking the connecting plates 910 can be improved, thereby improving the overall efficiency of the automatic riveting equipment. At the same time, since the connecting plates 910 may not be firmly adsorbed and may fall off the suction member 22 when the suction member 22 sucks the connecting plates 910, the connecting plates 910 are first placed in the plate placement space 3101 and then clamped by the pair of clamping fingers 421. This can improve the stability of the pair of clamping fingers 421 when clamping the connecting plates 910, thereby facilitating the pair of clamping fingers 421 to clamp the connecting plates 910 for subsequent operations.

[0052] Preferably, the gripping fingers 421 are implemented to include pneumatic fingers.

[0053] Specifically, the material suction and movement unit 21 includes a material suction and movement member 211, a suction and pipetting mounting member 212, and a material suction and driving member 213. The material suction and driving member 213 is mounted on the material suction and movement member 211 via the suction and pipetting mounting member 212 so as to be movable between the material discharge plate 111 and the plate placement space 3101 of the placement plate 31. The material suction member 22 is mounted on the material suction and driving member 213 so as to be driven by the material suction and driving member 213 and to press and absorb the connecting plate 910 placed on the material discharge plate 111.

[0054] As an example, when the suction member 22 sucks the connecting plate 910 and is driven by the suction moving member 211 to move to the vicinity of the placement plate 31 through the suction driving member 213 and the suction mounting member 212, the suction member 22 and the connecting plate 910 can be first driven by the suction driving member 213 to approach the plate placement space 3101, and then the connecting plate 910 can be placed in the plate placement space 3101, so that the connecting plate 910 in the plate placement space 3101 is clamped by a pair of the clamping fingers 421.

[0055] Preferably, the material suction moving member 211 is implemented as an electric cylinder, and the material suction driving member 213 is implemented as a pneumatic cylinder.

[0056] Preferably, the material suction member 22 forms a suction area 2201 and an air supply channel 2202 connected to the suction area 2201. The suction area 2201 is formed at a position where the material suction member 22 is driven by the material suction driving member 213 and pressed against the connecting plate 910, and the air supply channel 2202 is used to inflate and absorb air into the suction area 2201.

[0057] For example, when the material suction member 22 is driven by the material suction driving member 213 and pressed against the connecting plate 910, the gas in the adsorption area 2201 can be sucked through the air supply channel 2202, thereby allowing the connecting plate 910 to be sucked by the material suction member 22. Furthermore, the material suction member 22 is driven by the material suction moving member 211 to move to the vicinity of the placement plate 31 through the material suction driving member 213 and the suction mounting member 212, and when the material suction driving member 213 drives the material suction member 22 and the connecting plate 910 to approach the plate placement space 3101, air can be inflated into the adsorption area 2201 through the air supply channel 2202, thereby causing the connecting plate 910 sucked by the material suction member 22 to fall into the plate placement space 3101.

[0058] It should be noted that, in the process of sucking the gas in the adsorption area 2201 through the air supply channel 2202 , negative pressure will be formed outside the adsorption area 2201 of the suction member 22 , thereby adsorbing the connecting plate 910 and achieving absorption of the connecting plate 910 .

[0059] Preferably, the suction member 22 is implemented to include a suction cup.

[0060] In this embodiment, the placement mechanism 30 further includes a pushing assembly 32. The pushing assembly 32 includes a shifting drive member 321 and at least one shifting guide member 322. The placement plate 31 is engaged with the shifting guide member 322 in such a manner that it can move between a pair of the clamping fingers 421 and the material suction member 22 along the extension direction of the shifting guide member 322. The placement plate 31 is arranged at the output end of the shifting drive member 321, so that when the connecting plate 910 is placed in the plate placement space 3101, the placement plate 31 is driven by the shifting drive member 321 to move along the extension direction of the shifting guide member 322 and approach the pair of the clamping fingers 421, so that the pair of the clamping fingers 421 can clamp the connecting plate 910 in the plate placement space 3101.

[0061] Furthermore, the material clamping and shifting drive unit 41 includes a material clamping and moving member 411 and a lifting and lowering drive member 412. The material clamping and moving member 411 is located between the placement plate 31 and the press riveting support platform 52. The clamping member 42 is mounted on the material clamping and moving member 411 via the lifting and lowering drive member 412 so as to be movable between the placement plate 31 and the press riveting support platform 52.

[0062] As an example, the shifting drive member 321 drives the placement plate 31 to move along the extension direction of the shifting guide member 322 and approach a pair of the clamping fingers 421, and after the pair of the clamping fingers 421 move relative to each other to clamp the connecting plate 910 in the plate placement space 3101, the lifting drive member 412 drives the connecting plate 910 clamped by the pair of the clamping fingers 421 of the clamping member 42 to lift away from the placement plate 31, and the material clamping moving member 411 drives the connecting plate 910 clamped by the pair of the clamping fingers 421 to move toward the riveting support platform 52 through the lifting drive member 412.

[0063] Furthermore, after the material clamping moving member 411 drives the connecting plate 910 clamped by a pair of the clamping fingers 421 to move above the riveting support platform 52 through the lifting driving member 412, and one of the connecting holes 9101 of the connecting plate 910 corresponds to the riveted end 531 of the riveted member 53, the lifting driving member 412 will drive the connecting plate 910 clamped by a pair of the clamping fingers 421 to approach the riveting support platform 52 and enter the riveting support space 5201. At this time, the pair of the clamping fingers 421 move away from each other to release the connecting plate 910 to the riveting support space 5201 in a manner that one of the connecting holes 9101 corresponds to the riveted end 531. Furthermore, in the process of the pressure rivet 512 moving and driving the rivet nut 920 to move toward the riveted end 531, the riveted portion 921 of the rivet nut 920 is passed through the connecting hole 9101 corresponding to the riveted end 531 and abuts against the riveted end 531, and in the process of the pressure rivet 512 continuously pushing the rivet nut 920, the rivet nut 920 is riveted to the connecting hole 9101 of the connecting plate 910 by radial riveting with the riveted portion 921.

[0064] Among them, after the lifting drive part 412 drives the connecting plate 910 clamped by the pair of clamping fingers 421 of the clamping part 42 to lift off the placement plate 31, the connecting plate 910 can be prevented from falling off from between the pair of clamping fingers 421 due to accidentally colliding with the placement plate 31 during the process in which the material clamping moving part 411 drives the connecting plate 910 clamped by the pair of clamping fingers 421 to move away from the placement plate 31 through the lifting drive part 412.

[0065] Preferably, the lifting drive member 412 and the pushing assembly 32 are both implemented as cylinders. The clamping moving member 411 is implemented as an electric cylinder.

[0066] In another modified embodiment, the material clamping and shifting driving unit 41 includes a material clamping moving member 411, a lifting driving member 412 and a telescopic driving member 413. The material clamping moving member 411 is located between the placement plate 31 and the riveting support platform 52. The telescopic driving member 413 is arranged on the material clamping moving member 411 through the lifting driving member 412 in a manner that it can move between the placement plate 31 and the riveting support platform 52. The clamping member 42 is arranged on the telescopic driving member 413, so that when the material clamping moving member 411 drives the telescopic driving member 413 to move to the vicinity of the placement plate 31 through the lifting driving member 412, the pair of clamping fingers 421 of the clamping member 42 can be sent to the two sides of the connecting plate 910 in the plate placement space 3101 by the telescopic driving member 413, so as to clamp the connecting plate 910 in the plate placement space 3101 through the relative movement of a pair of clamping fingers 421.

[0067] As an example, after the pair of clamping fingers 421 move relative to each other and clamp the connecting plate 910 in the plate placement space 3101, the lifting drive member 412 will drive the connecting plate 910 clamped by the pair of clamping fingers 421 of the clamping member 42 to lift away from the placement plate 31 through the telescopic drive member 413. At the same time, the telescopic drive member 413 will drive the connecting plate 910 clamped by the pair of clamping fingers 421 away from the placement plate 31, so as to prevent the connecting plate 910 from falling off from between the pair of clamping fingers 421 during the process in which the material clamping moving member 411 drives the connecting plate 910 clamped by the pair of clamping fingers 421 to move toward the riveting support platform 52 through the lifting drive member 412 and the telescopic drive member 413.

[0068] Furthermore, after the telescopic driving member 413 drives the connecting plate 910, which is lifted off the placement plate 31, away from the placement plate 31 via the pair of clamping fingers 421, the material moving member 411 drives the connecting plate 910, which is clamped by the pair of clamping fingers 421, to move above the pressure riveting support platform 52 via the lifting driving member 412 and the telescopic driving member 413, and aligns one of the connecting holes 9101 of the connecting plate 910 with the riveted end 531 of the riveted member 53. The lifting driving member 412 drives the connecting plate 910, which is clamped by the pair of clamping fingers 421, to approach the pressure riveting support platform 52 and enter the pressure riveting support space 5201 via the telescopic driving member 413. At this time, the pair of clamping fingers 421 move away from each other, releasing the connecting plate 910 into the pressure riveting support space 5201 in a manner that one of the connecting holes 9101 corresponds to the riveted end 531. In the process of the pressure rivet 512 moving and driving the rivet nut 920 to move toward the riveted end 531, the riveted portion 921 of the rivet nut 920 is passed through the connecting hole 9101 corresponding to the riveted end 531 and abuts against the riveted end 531. In the process of the pressure rivet 512 continuously pushing the rivet nut 920, the rivet nut 920 is riveted to the connecting hole 9101 of the connecting plate 910 by radial riveting with the riveted portion 921.

[0069] Preferably, the lifting drive member 412 and the telescopic drive member 413 are both implemented as cylinders, the material clamping moving member 411 is implemented as an electric cylinder, and the pushing assembly 32 is implemented as a cylinder.

[0070] In order to enable those skilled in the art to understand the present invention, in at least one embodiment of the present invention, the placement mechanism 30 further includes the pushing assembly 32, the pushing assembly 32 includes the shifting drive member 321 and at least one shifting guide member 322, the placement plate 31 is engaged with the shifting guide member 322 in a manner that can be moved along the extension direction of the shifting guide member 322 and close to a pair of the clamping fingers 421, the placement plate 31 is arranged at the output end of the shifting drive member 321, the material clamping shifting drive unit 41 includes the material clamping moving member 411 and the material clamping shifting drive unit 41, the material clamping moving member 411 is located between the placement plate 31 and the riveting support platform 52, and the clamping member 42 is arranged on the material clamping moving member 411 through the lifting drive member 412 in a manner that can be moved between the placement plate 31 and the riveting support platform 52.

[0071] Preferably, the discharge member 11 further includes a plurality of positioning members 112, which are arranged on the discharge plate 111 in parallel with each other, and form a discharge space 1101 for stacking the plurality of connecting plates 910 between the plurality of positioning members 112 and the discharge plate 111. The plurality of positioning members 112 are used to prevent the plurality of connecting plates 910 from tilting as a whole when the plurality of connecting plates 910 are stacked on the discharge plate 111, thereby ensuring that the suction member 22 can absorb the connecting plates 910.

[0072] In one embodiment, there are four discharge plates 111. The feeding mechanism 10 further includes a conversion member 12, which includes a feed mounting disc 121 and a conversion drive 122. The four discharge plates 111 are evenly distributed along the circumference of the feed mounting disc 121, and the feed mounting disc 121 is mounted on the conversion drive 122. When the multiple connecting plates 910 stacked on one of the discharge plates 111 are sucked up by the suction member 22, the conversion drive 122 drives the feed mounting disc 121 to rotate, causing another discharge plate 111 stacked with multiple connecting plates 910 to move below the suction member 22. This reduces the time required to replace another discharge plate 111 stacked with multiple connecting plates 910, thereby improving the continuity of the suction member 22 sucking up the connecting plates 910 and thereby increasing production efficiency.

[0073] Preferably, the conversion drive 122 is implemented to include a motor.

[0074] It should be noted that the front of the connecting plate 910 has an identification code. In order to prevent the identification code on the surface of the connecting plate 910 from being blocked when the energy absorption box is installed on the automobile frame through the connecting plate 910, after the rivet nut 920 is riveted to the connecting plate 910, the rivet nut 920 needs to protrude from the reverse side of the connecting plate 910 that does not have an identification code, so that the model of the damaged energy absorption box can be checked by the identification code during maintenance, thereby facilitating maintenance and replacement. In this solution, the reverse side of the connecting plate 910 that does not have an identification code faces upward, so that the connecting plate 910 in the plate placement space 3101 is clamped by a pair of the clamping fingers 421 and moved into the riveting support space 5201, and when the rivet nut 920 is riveted to the connecting plate 910, the rivet nut 920 can protrude from the reverse side of the connecting plate 910 that does not have an identification code.

[0075] Preferably, the placement mechanism 30 further includes a photographing and detecting member 33. The photographing and detecting member 33 is positioned toward the connecting plate 910 placed in the board placement space 3101, with a predetermined distance between the photographing and detecting member 33 and the placement plate 31. The photographing and detecting member 33 is configured to photograph and detect the surface of the connecting plate 910 when the connecting plate 910 is placed in the board placement space 3101.

[0076] Preferably, the photographing and detecting component 33 is implemented to include a charge coupled device.

[0077] Preferably, the photographing detection member 33 is arranged to face the lower surface of the connecting plate 910 in the plate placement space 3101 .

[0078] As an example, when the photographing detection part 33 detects that there is an identification code on the surface of the connecting plate 910, it means that the connecting plate 910 is placed correctly, indicating that at this time a pair of the clamping fingers 421 can clamp the connecting plate 910 into the riveting support space 5201 and rivet the rivet nut 920 to the connecting hole 9101 of the connecting plate 910.

[0079] Furthermore, when the photographing detection part 33 detects that there is no identification code on the surface of the connecting plate 910, it means that the connecting plate 910 is placed incorrectly, which means that after a pair of the clamping fingers 421 take the connecting plate 910 out of the plate placement space 3101, the connecting plate 910 cannot be clamped into the rivet support space 5201 for subsequent operations until the next connecting plate 910 is placed in the plate placement space 3101 with the reverse side facing up.

[0080] Preferably, when the connecting plate 910 is placed incorrectly in the plate placement space 3101, the connecting plate 910 can be clamped by a pair of clamping fingers 421 and flipped over so that the reverse side of the connecting plate 910 faces upward, and the connecting plate 910 with the reverse side facing upward can be placed in the rivet support space 5201 and subsequent operations can be performed.

[0081] In this embodiment, the placement mechanism 30 also includes a perforated member 34 corresponding to the connecting hole 9101 of the connecting plate 910, and the perforated member 34 is used to be inserted into the connecting hole 9101 of the connecting plate 910 placed in the plate placement space 3101, thereby fixing the position of the connecting plate 910 in the plate placement space 3101 through the perforated member 34.

[0082] It is worth mentioning that after the lifting drive member 412 drives the connecting plate 910 clamped by a pair of the clamping fingers 421 of the clamping member 42 to lift off the placement plate 31, the perforated member 34 can be detached from the connecting hole 9101 to prevent the connecting plate 910 from being blocked by the perforated member 34 when the material clamping moving member 411 drives the connecting plate 910 clamped by a pair of the clamping fingers 421 to move away from the placement plate 31 through the lifting drive member 412.

[0083] Preferably, the outer diameter of the perforating member 34 gradually decreases from close to the placement plate 31 to away from the placement plate 31, and the outer diameter of the perforating member 34 close to the placement plate 31 is adapted to the inner diameter of the connecting hole 9101, so as to improve the smoothness of the perforating member 34 when inserted into the connecting hole 9101, so that the connecting plate 910 in the plate placement space 3101 can be smoothly fixed.

[0084] It should be noted that due to the influence of the production process, the inner diameter of the connecting hole 9101 placed on the connecting plate 910 may be smaller than the outer diameter of the riveted portion 921. At this time, the riveted portion 921 of the rivet nut 920 will not be able to pass through the connecting hole 9101, thereby making it impossible to press the rivet nut 920 to the connecting plate 910.

[0085] Those skilled in the art will appreciate that, because the outer diameter of the perforated member 34 gradually decreases from near the placement plate 31 to far from the placement plate 31, when the connecting plate 910 is placed in the plate placement space 3101 and each perforated member 34 penetrates the corresponding connecting hole 9101, if the inner diameter of one connecting hole 9101 does not meet the requirements, the entire connecting plate 910 will be skewed. By photographing the state of the identification code on the surface of the connecting plate 910 with the photographing detection member 33, it can be determined whether the inner diameter of the connecting hole 9101 of the connecting plate 910 meets the requirements.

[0086] As an example, when the identification code on the surface of the connecting plate 910 in the board placement space 3101 is photographed and identified by the shooting detection part 33 as being skewed as a whole, it means that the inner diameter of the connecting hole 9101 does not meet the requirements, that is, the connecting plate 910 is unqualified. After the pair of clamping fingers 421 clamp the connecting plate 910, the connecting plate 910 cannot be clamped into the rivet support space 5201 for subsequent operations; when the identification code on the surface of the connecting plate 910 in the board placement space 3101 is photographed and identified by the shooting detection part 33 as being flat as a whole, it means that the inner diameter of the connecting hole 9101 meets the requirements, and the pair of clamping fingers 421 can clamp the connecting plate 910 into the rivet support space 5201 for subsequent operations.

[0087] Preferably, the pressure riveting assembly 51 further includes a plurality of attracting members 513. The plurality of attracting members 513 are disposed at the contact point between the pressure riveting member 512 and the rivet nut 920, and are used to attract the rivet nut 920 when the pressure riveting member 512 drives the rivet nut 920 to move toward the riveted end 531, so that the riveted portion 921 of the rivet nut 920 can stably pass through the connecting hole 9101.

[0088] Preferably, the attracting member 513 is implemented to include a magnet.

[0089] Specifically, the rivet 512 forms a nut fixing portion 5121 toward the riveted end 531 for passing through the nut hole 9201 of the rivet nut 920. The outer diameter of the nut fixing portion 5121 is adapted to the inner diameter of the nut hole 9201.

[0090] As an example, when the rivet 512 moves toward the riveted end 531, the nut fixing portion 5121 will pass through the nut hole 9201, and at the same time, the multiple attraction members 513 will adsorb the rivet nut 920, so that the rivet nut 920 can stably pass the riveted portion 921 through the connecting hole 9101 under the drive of the rivet 512.

[0091] Preferably, the riveting mechanism 50 further includes a positioning assembly 54. The positioning assembly 54 includes a rebound rod 541 and a positioning rebound member 542. The rivet member 53 forms a positioning accommodating space 5301 along the axial direction. The rebound rod 541 is arranged in the positioning accommodating space 5301 in a coaxial manner with the riveting end 531. The rebound rod 541 has a penetration end 5411 that is coaxial with the riveting end 531 and extends into the positioning accommodating space 5301. The penetration end 5411 matches the inner diameter of the connecting hole 9101, so that when the connecting plate 910 is placed in the riveting support space 5201 in a manner that the connecting hole 9101 corresponds to the riveting end 531, the penetration end 5411 penetrates into the connecting hole 9101 to achieve the purpose of stabilizing the connecting plate 910. The positioning rebound member 542 is arranged between the end of the rebound rod 541 away from the insertion end 5411 and the inner wall of the positioning accommodating space 5301 , and the positioning rebound member 542 is used to realize the reciprocating movement of the rebound rod 541 in the axial direction of the positioning accommodating space 5301 .

[0092] Those skilled in the art will appreciate that, after the connecting plate 910 is placed in the pressure riveting support space 5201 with the connecting hole 9101 corresponding to the riveting end 531, the penetration end 5411 will enter the connecting hole 9101 and abut against the inner wall of the connecting hole 9101 to stabilize the connecting plate 910. At this time, the nut hole 9201 of the rivet nut 920 will be inserted by the nut fixing portion 5121 when the pressure rivet member 512 pushes the rivet nut 920. In the process of the riveting portion 921 entering the connecting hole 9101, the riveting portion 921 will push the penetration end 5411 into the pressure riveting support space 5201, and at the same time, the positioning resilient member 542 will be compressed and deformed. After the riveted portion 921 of the rivet nut 920 completely passes through the connecting hole 9101 and abuts against the riveted end 531, as the rivet nut 920 is continuously pushed by the pressure riveting component 512, the riveted portion 921 will be guided by the riveted end 531 and folded along the radial direction of the riveted end 531 to be riveted into the connecting plate 910, thereby riveting the rivet nut 920 as a whole to the connecting hole 9101 corresponding to the riveted end 531.

[0093] Furthermore, after the connection hole 9101 of the connection plate 910 corresponding to the riveting end 531 is riveted with the rivet nut 920, the pair of clamping fingers 421 clamp the connection plate 910 and lift the connection plate 910 off the riveting support platform 52 via the lifting drive 412. At this time, the rebound rod 541, under the action of the restoring force of the positioning rebound member 542, pushes the penetration end 5411 of the rebound rod 541 back to a position coaxial with the riveting end 531 and extending into the positioning accommodating space 5301, ready to enter the connection hole 9101 of the next connection plate 910.

[0094] Preferably, the pressure riveting mechanism 50 further includes a displacement sensor 55. The displacement sensor 55 is disposed toward a portion of the pressure riveting component 512 and is configured to detect the displacement distance of the pressure riveting component 512 when driven by the pressure riveting driver 511. When the pressure riveting component 512 is driven by the pressure riveting driver 511 and drives the rivet nut 920 toward the position of the riveted end 531, the displacement distance of the pressure riveting component 512 is detected to determine whether the riveted portion 921 of the rivet nut 920 has passed through the connecting hole 9101.

[0095] For example, on one hand, when the displacement sensor 55 detects that the displacement distance of the rivet 512 when driven by the rivet driver 511 is less than a predetermined value, it indicates that the riveted portion 921 of the rivet nut 920 has not passed through the connection hole 9101. In this case, the rivet is unqualified and requires manual inspection to check whether there is a mechanical failure. On the other hand, when the displacement sensor 55 detects that the displacement distance of the rivet 512 when driven by the rivet driver 511 is greater than a predetermined value, the rivet nut 920 may not be placed between the rivet 512 and the riveted end 531. In this case, the rivet is unqualified and requires manual inspection to eliminate the fault.

[0096] It should be noted that when the pressure riveting member 512 continuously pushes the rivet nut 920 and the riveted portion 921 is guided by the riveted end 531 and folded along the radial direction of the riveted end 531 to be riveted into the connecting plate 910, the pressure applied by the pressure riveting member 512 to the rivet nut 920 needs to be a predetermined value to ensure that the rivet nut 920 is entirely riveted to the connecting hole 9101 corresponding to the riveted end 531. The pressure riveting member 512 then rivets the rivet nut 920 entirely to the connecting hole 9101 corresponding to the riveted end 531.

[0097] Preferably, the pressure riveting mechanism 50 further includes a pressure sensor 56. The pressure sensor 56 is provided on the pressure riveting component 512 and is used to detect the pressure applied by the pressure riveting component 512 to the rivet nut 920, so as to ensure that after the riveted portion 921 of the rivet nut 920 passes through the connection hole 9101 corresponding to the riveted end 531, the rivet nut 920 can be entirely pressure-riveted to the connection hole 9101 of the connecting plate 910.

[0098] It will be understood by those skilled in the art that when the pressure sensor 56 detects that the pressure applied by the rivet 512 to the rivet nut 920 does not match the predetermined value, it indicates that the operation of riveting the rivet nut 920 to the connecting hole 9101 of the connecting plate 910 is unqualified.

[0099] In this embodiment, the automatic riveting equipment further includes a discharge conveyor mechanism 60. The discharge conveyor mechanism 60 is positioned along the path along which the pair of clamping fingers 421 of the clamping member 42 are moved by the material clamping moving member 411 via the lifting drive member 412. The discharge conveyor mechanism 60 forms a conveying channel 61. The conveying channel 61 is used to convey the connecting plate 910, having the rivet nut 920 press-riveted to it, through the connecting hole 9101.

[0100] It can be understood by those skilled in the art that after the rivet nut 920 is press-riveted into each of the connection holes 9101 of the connection plate 910 in the press-riveting support space 5201, the clamping moving member 411 drives the pair of clamping fingers 421 of the clamping member 42 to move through the lifting drive member 412, and the pair of clamping fingers 421 are respectively located on both sides of the connection plate 910 in the press-riveting support space 5201, so as to clamp the connection plate 910 by the relative movement of the pair of clamping fingers 421, and After the holding fingers 421 clamp the connecting plate 910, the material clamping moving part 411 drives the pair of clamping fingers 421 of the clamping part 42 to move to a predetermined position above the conveying channel 61 through the lifting drive part 412, so that after the pair of clamping fingers 421 move away from each other, the connecting plate 910 with the rivet nut 920 riveted in each connecting hole 9101 is placed on the conveying channel 61, so that the connecting plate 910 with the rivet nut 920 riveted thereon can be subsequently operated on under the conveyance of the conveying channel 61.

[0101] Preferably, the automatic riveting device further includes a waste collector 70. The waste collector 70 includes at least one waste collector 70. The waste collector 70 is positioned along the path where the pair of clamping fingers 421 of the clamping member 42 are moved by the material clamping moving member 411 via the lifting drive member 412. The waste collector 70 is used to store connecting plates 910 whose inner diameters of the connecting holes 9101 do not meet the requirements and to store connecting plates 910 that failed to meet the requirements when the rivet nuts 920 were riveted into the connecting holes 9101.

[0102] It will be understood by those skilled in the art that, on the one hand, when the surface of the connecting plate 910 is detected by the photographing detection part 33 as having no identification code, it indicates that the placement position of the connecting plate 910 in the plate placement space 3101 is unqualified. At this time, a pair of the clamping fingers 421 will move relative to each other and clamp the connecting plate 910, so that after the clamping moving part 411 drives the pair of the clamping fingers 421 of the clamping part 42 to move above the waste collecting part 70 through the lifting drive part 412, the unqualified connecting plate 910 is placed in the waste collecting part 70 by moving the pair of the clamping fingers 421 away from each other.

[0103] On the other hand, when the rivet nut 920 at the connecting hole 9101 of the connecting plate 910 is unqualified by press riveting and the inner diameter of the connecting hole 9101 does not meet the requirements, the pair of clamping fingers 421 will move relative to each other and clamp the connecting plate 910, and after the clamping moving part 411 drives the pair of clamping fingers 421 of the clamping part 42 to move above the waste collecting part 70 through the lifting drive part 412, the connecting plate 910 with an unqualified placement position is placed in the waste collecting part 70 by moving the pair of clamping fingers 421 away from each other.

[0104] Preferably, the automatic riveting device further includes a nut feeding mechanism 80. The nut feeding mechanism 80 includes a release assembly 81. The release assembly 81 includes a pair of release flipping members 811 and a pair of release return members 812, and the release return members 812 correspond to the release flipping members 811. The pair of release flipping members 811 are arranged between the riveting member 512 and the flip riveting end 531, and the pair of release flipping members 811 are arranged opposite to each other, and a nut placement space 8101 for placing the rivet nut 920 is provided between the pair of release flipping members 811, and the nut placement space 8101 is formed above the pair of release flipping members 811 in the direction of gravity. The release fixing member 813 is provided on the riveting support platform 52. The release flip member 811 is movably arranged on the release fixing member 813 through the release return member 812, so that when the rivet member 512 is driven by the rivet driving member 511 and drives the rivet nut 920 located in the nut placement space 8101 to move toward the flip rivet end 531, the release return member 812 is deformed to cause the release flip member 811 to offset, thereby causing the rivet nut 920 to fall from the nut placement space 8101, and the flip rivet portion 921 of the rivet nut 920 can smoothly pass through the connecting hole 9101 and abut against the flip rivet end 531.

[0105] The nut feeding mechanism 80 further includes a nut feeding member 82 and a guide unit 83. The nut feeding member 82 is located near the release assembly 81, and the guide unit 83 is provided between the nut feeding member 82 and the release fixture 813. The guide unit 83 is used to guide the rivet nut 920 fed by the nut feeding member 82, with the riveting portion 921 facing downward, into the nut placement space 8101.

[0106] Preferably, the nut supply member 82 includes a vibration plate. The nut supply member 82 is used to turn the riveted portion 921 of the rivet nut 920 downward and deliver the rivet nut 920 to the guide unit 83.

[0107] In this embodiment, the guide unit 83 includes a first guide nut member 831 and a second guide tube member 832. The first guide nut member 831 forms a first delivery channel, and the second guide tube member 832 forms a second guide channel. One end of the first delivery channel is connected to the nut supply member 82, and the other end of the first delivery channel corresponds to one end of the second guide channel. The release fixture 813 has a guide channel 8131 for passing the rivet nut 920, and forms a stop wall 8132. The stop wall 8132 is located in the extension direction of the guide channel 8131, and a stop space 81301 is formed between the stop wall 8132 and the guide channel 8131 for the rivet nut 920 to slide through the guide channel 8131 and hit the stop wall 8132. The other end of the second guide channel is connected to the end of the guide channel 8131 away from the stop space 81301. The release assembly 81 also includes a nut pusher 814 and a push member 815. The nut pusher 814 is arranged toward the stop space 81301 and toward the nut placement space 8101. The push member 815 is arranged on the nut pusher 814 in a manner that it can pass through the stop space 81301 and move toward the nut placement space 8101.

[0108] It can be understood that after the rivet nut 920 enters the first delivery channel with the riveted portion 921 facing downward, the rivet nut 920 will pass through the first delivery channel, the second guide channel and the guide channel 8131 in sequence, and hit the stop wall 8132 to stop in the stop space 81301. At this time, the nut pusher 814 will drive the push member 815 to move toward the nut placement space 8101, so as to push the rivet nut 920 docked in the stop space 81301 into the nut placement space 8101 through the push member 815 for subsequent operations.

[0109] In another variant embodiment, the release fixture 813 has a guide channel 8131 for passing the rivet nut 920. The guide unit 83 includes a first guide nut member 831 and a second guide tube member 832. The first guide nut member 831 forms a first delivery channel, and the second guide tube member 832 forms a second guide channel. One end of the first delivery channel is connected to the nut supply member 82, and the other end of the first delivery channel corresponds to one end of the second guide channel. The other end of the second guide channel is connected to one end of the guide channel 8131. The guide channel 8131 faces the nut placement space 8101.

[0110] It can be understood that after the rivet nut 920 enters the first delivery channel with the riveted portion 921 facing downward, the rivet nut 920 will pass through the first delivery channel, the second guide channel and the guide channel 8131 in sequence, and enter the nut placement space 8101 under the guidance of the guide channel 8131 for subsequent operations.

[0111] In order to enable those skilled in the art to understand the present invention, in at least one embodiment of the present invention, the guide unit 83 only includes the first guide nut member 831 and the second guide tube member 832, the first guide nut member 831 forms the first delivery channel, the second guide tube member 832 forms the second guide channel, one end of the first delivery channel is connected to the nut supply member 82, and the other end of the first delivery channel corresponds to one end of the second guide channel, the release fixing member 813 has the guide channel 8131 for passing the rivet nut 920, and forms the stop wall 8132, the stop wall 8132 is located in the extension direction of the guide channel 8131, and the stop wall 8132 is located in the extension direction of the guide channel 8131, and the stop wall 8132 is located in the extension direction of the guide channel 8131. The stop space 81301 is formed between the retaining wall 8132 and the guide channel 8131 for the rivet nut 920 that has passed through the guide channel 8131 and hit the stop wall 8132. The other end of the second guide channel is connected to the end of the guide channel 8131 away from the stop space 81301. The release assembly 81 also includes the nut pusher 814 and the push member 815. The nut pusher 814 is arranged to face the stop space 81301 and the nut placement space 8101. The push member 815 is arranged on the nut pusher 814 in a manner that it can pass through the stop space 81301 and move toward the nut placement space 8101.

[0112] Preferably, the release return member 812 is implemented as a torsion spring. The nut pusher 814 is implemented as a cylinder.

[0113] In this embodiment, the guide unit 83 further includes at least one vent pipe 833. The vent pipe 833 is connected to one end of the second guide channel near the first delivery channel. When the rivet nut 920 enters the second guide channel, air is blown into the second guide channel through the vent pipe 833, thereby improving the smoothness of the rivet nut 920 sliding through the second guide channel and the guide channel 8131, thereby preventing the rivet nut 920 from getting stuck on the inner walls of the second guide channel and the guide channel 8131 and being unable to slide into the stop space 81301.

[0114] In another modified embodiment, the guide unit 83 further includes at least one vent pipe 833. The vent pipe 833 is connected to one end of the guide channel 8131 near the stop wall 8132. When the rivet nut 920 enters the second guide channel, air is drawn into the guide channel 8131 through the vent pipe 833, thereby improving the smoothness of the rivet nut 920 sliding through the second guide channel and the guide channel 8131, thereby preventing the rivet nut 920 from getting stuck on the inner walls of the second guide channel and the guide channel 8131 and being unable to slide into the stop space 81301.

[0115] Preferably, the extension direction of the first delivery channel of the first guide nut member 831 is offset from the extension direction of the second guide channel of the second guide tube member 832. The nut feeding mechanism 80 also includes a channel adjustment mechanism 84. The channel adjustment mechanism 84 includes a staggered driving member 841 and a staggered member 842. The staggered driving member 841 and the staggered member 842 are both located between the first delivery channel and the second guide channel, and the staggered member 842 forms a connecting space 84201. The connecting space 84201 can alternately connect with the first delivery channel and the second guide channel when the staggered member 842 is driven by the staggered driving member 841. The connecting space 84201 is adapted to fit the rivet nut 920.

[0116] It can be understood by those skilled in the art that when a plurality of the rivet nuts 920 push each other and enter the first delivery channel of the first guide nut member 831, the staggered member 842 will be driven by the staggered driving member 841 to connect the communicating space 84201 of the staggered member 842 with the first delivery channel. At this time, the rivet nut 920 close to the staggered driving member 841 in the first delivery channel will be pushed into the communicating space 84201 by other rivet nuts 920 in the first delivery channel, and the staggered driving member 841 will drive the staggered member 842 again. The staggered piece 842 is connected to the connecting space 84201 of the staggered piece 842 and the second guide channel. The rivet nut 920 will slide into the second guide channel due to gravity. In the process of blowing air into the second guide channel through the ventilation pipe 833, the rivet nut 920 will slide through the second guide channel and the guide channel 8131 and stop in the stop space 81301 after hitting the stop wall 8132. The rivet nut 920 in the stop space 81301 will be pushed into the nut placement space 8101 by the push piece 815.

[0117] It is worth mentioning that due to the setting of the staggered drive member 841, the rivet nut 920 can enter the second guide channel and the guide channel 8131 individually and stop at the stop space 81301 after hitting the stop wall 8132, so as to avoid multiple rivet nuts 920 entering the second guide channel and the guide channel 8131 at the same time, thereby avoiding the situation where the ventilation pipe 833 is blocked by multiple rivet nuts 920 when blowing air into the second guide channel and cannot blow air smoothly, and preventing multiple rivet nuts 920 from being stuck in the second guide channel and the guide channel 8131 and unable to enter the stop space 81301.

[0118] Preferably, the staggered driving member 841 is implemented to include a cylinder.

[0119] Preferably, the nut feeding mechanism 80 further includes a nut detection member 85, which is arranged near a pair of the release flip members 811, and the nut detection member 85 faces the nut placement space 8101, so as to detect whether the rivet nut 920 is placed in the nut placement space 8101 through the nut detection member 85.

[0120] As an example, when there is no rivet nut 920 in the nut placement space 8101, it is necessary to check the guide channel 8131, the first delivery channel, the second guide channel and the stop space 81301 to rule out the possibility that the rivet nut 920 is stuck in the guide channel 8131, the second guide channel and the stop space 81301.

[0121] When the rivet nut 920 is stuck in the guide channel 8131, the second guide channel and the stop space 81301, it is necessary to clean the guide channel 8131, the second guide channel and the stop space 81301 in time; when the rivet nut 920 is stuck in the guide channel 8131, the second guide channel and the stop space 81301, it is necessary to re-send the rivet nut 920 into the second guide channel, and make the rivet nut 920 pass through the second guide channel and the guide channel 8131 in turn and hit the stop wall 8132 before entering the stop space 81301, so as to drive the push member 815 through the nut pusher 814 to push the rivet nut 920 located in the stop space 81301 into the nut placement space 8101.

[0122] Preferably, the nut detector 85 is implemented to include a laser sensor.
