[0036] refer to Figures 1 to 17 A riveting device according to a preferred embodiment of the present invention will be described in detail below, wherein the riveting device includes a riveting mechanism 10 and a clamping and moving mechanism 20.

[0037] Specifically, the rivet mechanism 10 is used to rivet a rivet nut 920 in each connection hole 9101 of the connecting plate 910. The rivet mechanism 10 includes a rivet assembly 11, a rivet support platform 12, and a rivet member 13. The rivet support platform 12 forms a rivet support space 1201 for placing the connecting plate 910. The rivet member 13 is arranged on the rivet support platform 12, and the rivet member 13 has a rivet end 131 protruding toward the rivet support space 1201, and the rivet end 131 corresponds to the connection hole 9101 of the connecting plate 910. The rivet assembly 11 includes a rivet driver 111 and a rivet member 112. The press riveting driver 111 is located near the press riveting support platform 12 and faces the riveting end 131. The press riveting driver 111 is arranged on the press riveting driver 111 in a manner that it can move toward the riveting end 131. When the connecting plate 910 is placed in the press riveting support space 1201 with the connecting hole 9101 corresponding to the riveting end 131, the press riveting driver 112 drives the rivet nut 920 to continuously move toward the riveting end 131, and the riveting portion 921 of the rivet nut 920 passes through the connecting hole 9101 and abuts against the riveting end 131, thereby riveting the rivet nut 920 to the connecting plate 910 in a radial riveting manner.

[0038] The clamping and shifting mechanism 20 includes a clamping and shifting drive unit 21 and a clamping member 22. The clamping and shifting drive unit 21 is located near the press riveting support platform 12. The clamping member 22 is disposed on the clamping and shifting drive unit 21 so as to be able to move closer to and farther from the press riveting support platform 12. The clamping member 22 has a pair of clamping fingers 221 that can move relative to and away from each other.

[0039] Those skilled in the art can understand that, after the pair of clamping fingers 221 are moved away from the riveting support platform 12 by the clamping material shifting driving unit 21, and the pair of clamping fingers 221 of the clamping member 22 are moved away from each other, the connecting plate 910 is manually placed between the pair of clamping fingers 221, so that the connecting plate 910 is clamped by the relative movement of the pair of clamping fingers 221, and the clamping material shifting driving unit 21 drives the connecting plate 910 to a predetermined position above the riveting support platform 12 through the pair of clamping fingers 221, and at the same time makes the connecting hole 9101 correspond to the riveting end 131, and then the connecting plate 910 is released to the riveting support space 1201 by the away movement of the pair of clamping fingers 221, so as to perform the operation of riveting the rivet nut 920 to the connecting hole 9101 of the connecting plate 910.

[0040] Preferably, the gripping fingers 221 are implemented to include pneumatic fingers.

[0041] Preferably, the riveting driver 111 is implemented to include a gas-liquid booster cylinder.

[0042] It is worth mentioning that since the connecting plate 910 is released to the riveting support space 1201 through a pair of the clamping fingers 221 in a manner that the connecting hole 9101 corresponds to the riveting end 131, the connecting plate 910 can be stably placed in the riveting support space 1201, and at the same time, the connecting plate 910 can be prevented from shaking and being unable to correspond the connecting hole 9101 to the riveting end 131, and the rivet nut 920 can be stably riveted to the connecting hole 9101 of the connecting plate 910 for stable production.

[0043] Among them, the connecting plate 910 is placed in the rivet support space 1201 through the clamping member 22 and the material clamping and shifting driving unit 21, which can avoid manual placement of the connecting plate 910 in the rivet support space 1201, thereby reducing the risk of manual hand being accidentally injured by the rivet 112 due to failure to move away from the rivet 112 in time.

[0044] Preferably, when the connecting plate 910 is placed in the pressure riveting support space 1201 in a manner such that the connecting hole 9101 corresponds to the riveting end 131, the rivet nut 920, the riveting portion 921 of the rivet nut 920, the connecting hole 9101 corresponding to the riveting end 131, and the riveting end 131 are sequentially arranged on the path where the pressure riveting component 112 is driven by the pressure riveting driver 111. The outer diameter of the rivet nut 920 is greater than the inner diameter of the connecting hole 9101, the outer diameter of the riveting portion 921 matches the inner diameter of the connecting hole 9101, and the rivet nut 920, the riveting portion 921, the connecting hole 9101, and the riveting end 131 are coaxial.

[0045] Preferably, the riveting device further includes a placement mechanism 30. The placement mechanism 30 includes a placement plate 31. The placement plate 31 is located near the clamping and shifting drive unit 21. The clamping and shifting drive unit 21 is located between the placement plate 31 and the riveting support platform 12. The placement plate 31 forms a plate placement space 3101 adapted for the connecting plate 910. The plate placement space 3101 is used to place the connecting plate 910 to be clamped by the pair of clamping fingers 221.

[0046] As an example, after the connecting plate 910 is placed in the plate placement space 3101, the pair of clamping fingers 221 of the clamping member 22 will be moved to the vicinity of the placement plate 31 through the material clamping shift drive unit 21 to clamp the connecting plate 910 through the relative movement of the pair of clamping fingers 221.

[0047] It is worth mentioning that the connecting plate 910 is first placed in the plate placement space 3101 and then clamped by a pair of the clamping fingers 221, which can prevent the connecting plate 910 from being accidentally injured by the pair of the clamping fingers 221 when being manually placed between the pair of the clamping fingers 221.

[0048] In this embodiment, the placement mechanism 30 further includes a pushing assembly 32. The pushing assembly 32 includes a shifting drive 321 and at least one shifting guide 322. The placement plate 31 is engaged with the shifting guide 322 in such a manner that it can move closer to and further away from a pair of clamping fingers 221 along the extension direction of the shifting guide 322. The placement plate 31 is disposed at the output end of the shifting drive 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 321 to move along the extension direction of the shifting guide 322 and closer to a pair of clamping fingers 221, so that the pair of clamping fingers 221 can clamp the connecting plate 910 in the plate placement space 3101.

[0049] The clamping and shifting drive unit 21 includes a clamping and moving member 211 and a lifting and lowering drive member 212. The clamping and moving member 211 is located between the placement plate 31 and the press riveting support platform 12. The clamping member 22 is mounted on the clamping and moving member 211 via the lifting and lowering drive member 212 so as to be movable between the placement plate 31 and the press riveting support platform 12.

[0050] As an example, the shift drive 321 drives the placement plate 31 to move along the extension direction of the shift guide 322 and approach a pair of the clamping fingers 221, and after the pair of the clamping fingers 221 move relative to each other to clamp the connecting plate 910 in the plate placement space 3101, the lifting drive 212 will drive the connecting plate 910 clamped by the pair of the clamping fingers 221 of the clamping member 22 to lift away from the placement plate 31, and the material clamping moving member 211 drives the connecting plate 910 clamped by the pair of the clamping fingers 221 to move toward the riveting support platform 12 through the lifting drive 212.

[0051] Furthermore, after the material clamping moving member 211 drives the connecting plate 910 clamped by a pair of the clamping fingers 221 to move above the riveting support platform 12 through the lifting driving member 212, and one of the connecting holes 9101 of the connecting plate 910 corresponds to the riveted end 131 of the riveted member 13, the lifting driving member 212 will drive the connecting plate 910 clamped by a pair of the clamping fingers 221 to approach the riveting support platform 12 and enter the riveting support space 1201. At this time, the pair of the clamping fingers 221 move away from each other to release the connecting plate 910 to the riveting support space 1201 in a manner that one of the connecting holes 9101 corresponds to the riveted end 131. Furthermore, in the process of the pressure rivet 112 moving and driving the rivet nut 920 to move toward the riveted end 131, the riveted portion 921 of the rivet nut 920 passes through the connecting hole 9101 corresponding to the riveted end 131 and abuts against the riveted end 131, and in the process of the pressure rivet 112 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.

[0052] Among them, since the lifting drive part 212 drives the connecting plate 910 clamped by the pair of clamping fingers 221 of the clamping part 22 to lift off the placement plate 31, the connecting plate 910 can be prevented from falling off from between the pair of clamping fingers 221 due to accidentally colliding with the placement plate 31 during the process of the material clamping moving part 211 driving the connecting plate 910 clamped by the pair of clamping fingers 221 to move away from the placement plate 31 through the lifting drive part 212.

[0053] Preferably, the lifting drive member 212 and the pushing assembly 32 are both implemented as cylinders. The clamping moving member 211 is implemented as an electric cylinder.

[0054] It is worth mentioning that since the placement plate 31 is first moved away from the pair of clamping fingers 221 and then the connecting plate 910 is placed in the placement space 3101 of the placement plate 31, it is convenient to place the connecting plate 910 in the placement space 3101, avoiding being obstructed by the pair of clamping fingers 221 when placing the connecting plate 910.

[0055] In another modified embodiment, the material clamping and shifting driving unit 21 includes a material clamping moving member 211, a lifting driving member 212 and a telescopic driving member 213. The material clamping moving member 211 is located between the placement plate 31 and the riveting support platform 12. The telescopic driving member 213 is arranged on the material clamping moving member 211 through the lifting driving member 212 in a manner that it can move between the placement plate 31 and the riveting support platform 12. The clamping member 22 is arranged on the telescopic driving member 213, so that when the material clamping moving member 211 drives the telescopic driving member 213 to move to the vicinity of the placement plate 31 through the lifting driving member 212, the pair of clamping fingers 221 of the clamping member 22 can be sent to the two sides of the connecting plate 910 in the plate placement space 3101 by the telescopic driving member 213, so as to clamp the connecting plate 910 in the plate placement space 3101 through the relative movement of a pair of clamping fingers 221.

[0056] As an example, after the pair of clamping fingers 221 move relative to each other and clamp the connecting plate 910 in the plate placement space 3101, the lifting drive member 212 will drive the connecting plate 910 clamped by the pair of clamping fingers 221 of the clamping member 22 to lift away from the placement plate 31 through the telescopic drive member 213. At the same time, the telescopic drive member 213 will drive the connecting plate 910 clamped by the pair of clamping fingers 221 away from the placement plate 31, so as to prevent the connecting plate 910 from falling off from between the pair of clamping fingers 221 during the process in which the material clamping moving member 211 drives the connecting plate 910 clamped by the pair of clamping fingers 221 to move toward the riveting support platform 12 through the lifting drive member 212 and the telescopic drive member 213.

[0057] Furthermore, after the telescopic driving member 213 drives the connecting plate 910, which is lifted off the placement plate 31, away from the placement plate 31 through the pair of clamping fingers 221, the material clamping moving member 211 drives the connecting plate 910 clamped by the pair of clamping fingers 221 to move above the pressure riveting support platform 12 through the lifting driving member 212 and the telescopic driving member 213, and aligns one of the connecting holes 9101 of the connecting plate 910 with the riveted end 131 of the riveted member 13. The lifting driving member 212 drives the connecting plate 910 clamped by the pair of clamping fingers 221 to approach the pressure riveting support platform 12 and enter the pressure riveting support space 1201 through the telescopic driving member 213. At this time, the pair of clamping fingers 221 move away from each other to release the connecting plate 910 into the pressure riveting support space 1201 in a manner that one of the connecting holes 9101 corresponds to the riveted end 131. In the process of the pressure rivet 112 moving and driving the rivet nut 920 to move toward the riveted end 131, the riveted portion 921 of the rivet nut 920 will pass through the connecting hole 9101 corresponding to the riveted end 131 and abut against the riveted end 131, and in the process of the pressure rivet 112 continuously pushing the rivet nut 920, the rivet nut 920 will be riveted to the connecting hole 9101 of the connecting plate 910 in a radial riveting manner by the riveted portion 921.

[0058] Preferably, the lifting drive member 212 and the telescopic drive member 213 are both implemented as cylinders, the material clamping moving member 211 is implemented as an electric cylinder, and the pushing assembly 32 is implemented as a cylinder.

[0059] 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 only 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 221, the placement plate 31 is arranged at the output end of the shifting drive member 321, the material clamping shifting drive unit 21 includes the material clamping moving member 211 and the material clamping shifting drive unit 21, the material clamping moving member 211 is located between the placement plate 31 and the riveting support platform 12, and the clamping member 22 is arranged on the material clamping moving member 211 through the lifting drive member 212 in a manner that can be moved between the placement plate 31 and the riveting support platform 12.

[0060] Preferably, the pressure riveting assembly 11 further includes a plurality of attracting members 113. The plurality of attracting members 113 are disposed at the contact point between the pressure riveting member 112 and the rivet nut 920, and are used to attract the rivet nut 920 when the pressure riveting member 112 drives the rivet nut 920 to move toward the riveting end 131, so that the riveting portion 921 of the rivet nut 920 can stably pass through the connecting hole 9101.

[0061] Preferably, the attracting member 113 is implemented to include a magnet.

[0062] Specifically, the rivet 112 forms a nut fixing portion 1121 toward the riveted end 131 for passing through the nut hole 9201 of the rivet nut 920. The outer diameter of the nut fixing portion 1121 is adapted to the inner diameter of the nut hole 9201.

[0063] As an example, when the rivet 112 moves toward the riveted end 131, the nut fixing portion 1121 will pass through the nut hole 9201, and at the same time, the multiple attraction members 113 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 112.

[0064] Preferably, the riveting mechanism 10 further includes a positioning assembly 14. The positioning assembly 14 includes a rebound rod 141 and a positioning rebound member 142. The rivet member 13 forms a positioning accommodating space 1301 along the axial direction. The rebound rod 141 is arranged in the positioning accommodating space 1301 in a coaxial manner with the riveting end 131. The rebound rod 141 has a penetration end 1411 that is coaxial with the riveting end 131 and extends into the positioning accommodating space 1301, and the penetration end 1411 matches the inner diameter of the connecting hole 9101, so that when the connecting plate 910 is placed in the riveting support space 1201 in a manner that the connecting hole 9101 corresponds to the riveting end 131, the penetration end 1411 penetrates into the connecting hole 9101 to achieve the purpose of stabilizing the connecting plate 910. The positioning rebound member 142 is arranged between the end of the rebound rod 141 away from the penetration end 1411 and the inner wall of the positioning accommodating space 1301 , and the positioning rebound member 142 is used to realize the reciprocating movement of the rebound rod 141 in the axial direction of the positioning accommodating space 1301 .

[0065] Those skilled in the art will appreciate that, after the connecting plate 910 is placed in the pressure riveting support space 1201 with the connecting hole 9101 corresponding to the riveting end 131, the insertion end 1411 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 1121 when the pressure rivet member 112 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 insertion end 1411 into the pressure riveting support space 1201, and at the same time, the positioning resilient member 142 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 131, as the rivet nut 920 is continuously pushed by the pressure riveting component 112, the riveted portion 921 will be guided by the riveted end 131 and folded along the radial direction of the riveted end 131 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 131.

[0066] Preferably, the pressure riveting mechanism 10 further includes a displacement sensor 15. The displacement sensor 15 is disposed toward a portion of the pressure riveting component 112 and is configured to detect the displacement distance of the pressure riveting component 112 when driven by the pressure riveting driver 111. When the pressure riveting component 112 is driven by the pressure riveting driver 111 and drives the rivet nut 920 toward the position of the riveted end 131, the displacement distance of the pressure riveting component 112 is detected to determine whether the riveted portion 921 of the rivet nut 920 has passed through the connection hole 9101.

[0067] For example, on one hand, when the displacement sensor 15 detects that the displacement distance of the rivet 112 when driven by the rivet driver 111 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 riveting is unqualified, and manual inspection is required to determine whether there is a mechanical failure. On the other hand, when the displacement sensor 15 detects that the displacement distance of the rivet 112 when driven by the rivet driver 111 is greater than a predetermined value, the rivet nut 920 may not be placed between the rivet 112 and the riveted end 131, or the rivet 112 may be over-riveted to the connection hole 9101 of the connecting plate 910. In this case, the riveting is unqualified, and manual inspection is required to eliminate the fault.

[0068] It should be noted that when the pressure riveting member 112 continuously pushes the rivet nut 920 and the riveted portion 921 is guided by the riveted end 131 and folded along the radial direction of the riveted end 131 to be riveted into the connecting plate 910, the pressure applied by the pressure riveting member 112 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 131. The pressure riveting member 112 then rivets the rivet nut 920 entirely to the connecting hole 9101 corresponding to the riveted end 131.

[0069] Preferably, the pressure riveting mechanism 10 further includes a pressure sensor 16. The pressure sensor 16 is provided on the pressure riveting component 112 and is used to detect the pressure applied by the pressure riveting component 112 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 131, the rivet nut 920 can be integrally pressure-riveted to the connection hole 9101 of the connecting plate 910.

[0070] It will be understood by those skilled in the art that when the pressure sensor 16 detects that the pressure applied by the rivet 112 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.

[0071] For example, after one of the rivet nut 920 is press-riveted to the connection hole 9101 corresponding to the riveting end 131, the connecting plate 910 can be clamped by the pair of clamping fingers 221 again, and driven by the lifting drive member 212 and the material clamping moving member 211, the connecting plate 910 clamped by the pair of clamping fingers 221 is placed in the riveting support space 1201 of the riveting support platform 12 in a manner such that another connection hole 9101 corresponds to the riveting end 131, so as to continue to press-rivet another rivet nut 920 to another connection hole 9101 corresponding to the riveting end 131. In this way, the rivet nut 920 is press-riveted in each of the connection holes 9101 of the connecting plate 910.

[0072] Preferably, the connecting line of each connecting hole 9101 of the connecting plate 910 is parallel to the direction in which the clamping member 22 is moved by the material clamping moving member 211 through the lifting drive member 212, so as to ensure that the material clamping shifting drive unit 21 can be driven by a pair of clamping fingers 221 of the clamping member 22 to place each connecting hole 9101 in the rivet support space 1201 in a manner such that the connecting hole 9101 corresponds to the rivet end 131.

[0073] It is worth mentioning that after the connection hole 9101 of the connecting plate 910 corresponding to the riveting end 131 is riveted with the rivet nut 920, the pair of clamping fingers 221 will clamp the connecting plate 910 and lift the connecting plate 910 away from the riveting support platform 12 through the lifting drive 212. At this time, the rebound rod 141 will, under the action of the restoring force of the positioning rebound member 142, push the penetration end 1411 of the rebound rod 141 back to a position coaxial with the riveting end 131 and extending into the positioning accommodating space 1301, ready to enter another connection hole 9101 of the connecting plate 910 or the connection hole 9101 of the next connecting plate 910.

[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 221 and moved into the riveting support space 1201, 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 221 can clamp the connecting plate 910 and send it to the riveting support space 1201, and can 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 221 take the connecting plate 910 out of the plate placement space 3101, the connecting plate 910 cannot be clamped into the riveting support space 1201 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 221 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 1201 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 212 drives the connecting plate 910 clamped by a pair of the clamping fingers 221 of the clamping member 22 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 211 drives the connecting plate 910 clamped by a pair of the clamping fingers 221 to move away from the placement plate 31 through the lifting drive member 212.

[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 221 clamp the connecting plate 910, the connecting plate 910 cannot be clamped into the rivet support space 1201 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 221 can clamp the connecting plate 910 into the rivet support space 1201 for subsequent operations.

[0087] Preferably, the pressure riveting device further includes a nut feeding mechanism 40. The nut feeding mechanism 40 includes a release assembly 41. The release assembly 41 includes a pair of release flip members 411 and a pair of release return members 412, and the release return members 412 correspond to the release flip members 411. The pair of release flip members 411 are arranged between the pressure riveting part 112 and the flip riveting end 131. The pair of release flip members 411 are arranged opposite to each other, and a nut placement space 4101 for placing the rivet nut 920 is provided between the pair of release flip members 411. The nut placement space 4101 is formed above the pair of release flip members 411 in the direction of gravity. The release fixing member 413 is provided on the pressure riveting support platform 12. The release flip member 411 is movably arranged on the release fixing member 413 through the release return member 412, so that when the rivet member 112 is driven by the rivet driving member 111 and drives the rivet nut 920 located in the nut placement space 4101 to move toward the flip rivet end 131, the release return member 412 is deformed to cause the release flip member 411 to offset, thereby causing the rivet nut 920 to fall from the nut placement space 4101, 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 131.

[0088] The nut feeding mechanism 40 further includes a nut feeding member 42 and a guide unit 43. The nut feeding member 42 is located near the release assembly 41, and the guide unit 43 is disposed between the nut feeding member 42 and the release fixture 413. The guide unit 43 is used to guide the rivet nut 920 fed by the nut feeding member 42, with the riveted portion 921 facing downward, into the nut placement space 4101.

[0089] Preferably, the nut supply member 42 includes a vibration plate. The nut supply member 42 is used to turn the riveted portion 921 of the rivet nut 920 downward and deliver the rivet nut 920 to the guide unit 43.

[0090] In this embodiment, the guide unit 43 includes a first guide nut member 431 and a second guide tube member 432. The first guide nut member 431 forms a first delivery channel, and the second guide tube member 432 forms a second guide channel. One end of the first delivery channel is connected to the nut supply member 42, and the other end of the first delivery channel corresponds to one end of the second guide channel. The release fixture 413 has a guide channel 4131 for passing the rivet nut 920, and forms a stop wall 4132. The stop wall 4132 is located in the extension direction of the guide channel 4131, and a stop space 41301 is formed between the stop wall 4132 and the guide channel 4131 for the rivet nut 920 to slide through the guide channel 4131 and hit the stop wall 4132. The other end of the second guide channel is connected to the end of the guide channel 4131 away from the stop space 41301. The release assembly 41 also includes a nut pusher 414 and a push member 415. The nut pusher 414 is arranged toward the stop space 41301 and toward the nut placement space 4101. The push member 415 is arranged on the nut pusher 414 in a manner that it can pass through the stop space 41301 and move toward the nut placement space 4101.

[0091] 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 4131 in sequence, and hit the stop wall 4132 to stop in the stop space 41301. At this time, the nut pusher 414 will drive the push member 415 to move toward the nut placement space 4101, so as to push the rivet nut 920 docked in the stop space 41301 into the nut placement space 4101 through the push member 415 for subsequent operations.

[0092] In another variant embodiment, the release fixture 413 has a guide channel 4131 for passing the rivet nut 920. The guide unit 43 includes a first guide nut member 431 and a second guide tube member 432. The first guide nut member 431 forms a first delivery channel, and the second guide tube member 432 forms a second guide channel. One end of the first delivery channel is connected to the nut supply member 42, 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 4131. The guide channel 4131 faces the nut placement space 4101.

[0093] 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 4131 in sequence, and enter the nut placement space 4101 under the guidance of the guide channel 4131 for subsequent operations.

[0094] 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 43 only includes the first guide nut member 431 and the second guide tube member 432, the first guide nut member 431 forms the first delivery channel, the second guide tube member 432 forms the second guide channel, one end of the first delivery channel is connected to the nut supply member 42, and the other end of the first delivery channel corresponds to one end of the second guide channel, the release fixing member 413 has the guide channel 4131 for passing the rivet nut 920, and forms the stop wall 4132, the stop wall 4132 is located in the extension direction of the guide channel 4131, and the stop wall 4132 is located in the extension direction of the guide channel 4131, and the stop wall 4132 is located in the extension direction of the guide channel 4131. The stop space 41301 is formed between the retaining wall 4132 and the guide channel 4131 for the rivet nut 920 to stop, slide through the guide channel 4131 and hit the stop wall 4132. The other end of the second guide channel is connected to the end of the guide channel 4131 away from the stop space 41301. The release assembly 41 also includes the nut pusher 414 and the pusher 415. The nut pusher 414 is arranged to face the stop space 41301 and the nut placement space 4101. The pusher 415 is arranged on the nut pusher 414 in a manner that it can pass through the stop space 41301 and move toward the nut placement space 4101.

[0095] Preferably, the release return member 412 is implemented to include a torsion spring. The nut pusher 414 is implemented to include a cylinder.

[0096] In this embodiment, the guide unit 43 further includes at least one vent pipe 433. The vent pipe 433 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 433, thereby improving the smoothness of the rivet nut 920 sliding through the second guide channel and the guide channel 4131, thereby preventing the rivet nut 920 from getting stuck on the inner walls of the second guide channel and the guide channel 4131 and being unable to slide into the stop space 41301.

[0097] In another modified embodiment, the guide unit 43 further includes at least one vent pipe 433. The vent pipe 433 is connected to one end of the guide channel 4131 near the stop wall 4132. When the rivet nut 920 enters the second guide channel, air is drawn into the guide channel 4131 through the vent pipe 433, thereby improving the smoothness of the rivet nut 920 sliding through the second guide channel and the guide channel 4131, thereby preventing the rivet nut 920 from getting stuck on the inner walls of the second guide channel and the guide channel 4131 and being unable to slide into the stop space 41301.

[0098] Preferably, the end of the second guide channel close to the first delivery channel is higher than the end of the second guide channel close to the guide channel 4131, so that the rivet nut 920 can slide into the guide channel 4131 under the action of gravity after entering the second guide channel.

[0099] Preferably, the extension direction of the first delivery channel of the first guide nut member 431 is offset from the extension direction of the second guide channel of the second guide tube member 432. The nut feeding mechanism 40 also includes a channel adjustment mechanism 44. The channel adjustment mechanism 44 includes a staggered driving member 441 and a staggered member 442. The staggered driving member 441 and the staggered member 442 are both located between the first delivery channel and the second guide channel, and the staggered member 442 forms a connecting space 44201. The connecting space 44201 can alternately connect with the first delivery channel and the second guide channel when the staggered member 442 is driven by the staggered driving member 441. The connecting space 44201 is adapted to fit the rivet nut 920.

[0100] 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 431, the staggered member 442 will be driven by the staggered driving member 441 to connect the communicating space 44201 of the staggered member 442 with the first delivery channel. At this time, the rivet nut 920 close to the staggered driving member 441 in the first delivery channel will be pushed into the communicating space 44201 by other rivet nuts 920 in the first delivery channel, and the staggered driving member 441 will drive the staggered member 442 again. The staggered piece 442 is connected to the connecting space 44201 of the staggered piece 442 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 433, the rivet nut 920 will slide through the second guide channel and the guide channel 4131 and stop in the stop space 41301 after hitting the stop wall 4132. The rivet nut 920 in the stop space 41301 will be pushed into the nut placement space 4101 by the push piece 415.

[0101] It is worth mentioning that, due to the setting of the staggered drive member 441, a single rivet nut 920 can enter the second guide channel and the guide channel 4131 and stop at the stop space 41301 after hitting the stop wall 4132, so as to avoid multiple rivet nuts 920 from entering the second guide channel and the guide channel 4131 at the same time, thereby avoiding the situation where the ventilation pipe 433 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 4131 and unable to enter the stop space 41301.

[0102] Preferably, the staggered driving member 441 is implemented to include a cylinder.

[0103] Preferably, the nut feeding mechanism 40 further includes a nut detection member 45, which is arranged near a pair of the release flip members 411, and the nut detection member 45 faces the nut placement space 4101, so as to detect whether the rivet nut 920 is placed in the nut placement space 4101 through the nut detection member 45.

[0104] As an example, when there is no rivet nut 920 in the nut placement space 4101, it is necessary to check the guide channel 4131, the first delivery channel, the second guide channel and the stop space 41301 to rule out the possibility that the rivet nut 920 is stuck in the guide channel 4131, the second guide channel and the stop space 41301.

[0105] Furthermore, when the rivet nut 920 is stuck in the guide channel 4131, the second guide channel and the stop space 41301, it is necessary to clean the guide channel 4131, the second guide channel and the stop space 41301 in time; when the rivet nut 920 is stuck in the guide channel 4131, the second guide channel and the stop space 41301, 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 4131 in turn and hit the stop wall 4132 before entering the stop space 41301, so as to drive the push member 415 through the nut pusher 414 to push the rivet nut 920 located in the stop space 41301 into the nut placement space 4101.

[0106] Preferably, the nut detector 45 is implemented to include a laser sensor.

[0107] In this embodiment, the press riveting device capable of automatically feeding nuts further includes a discharge conveyor mechanism 50. The discharge conveyor mechanism 50 is positioned along the path along which the pair of clamping fingers 221 of the clamping member 22 are moved by the material clamping moving member 211 via the lifting drive member 212. The discharge conveyor mechanism 50 forms a conveying channel 51. The conveying channel 51 is used to convey the connecting plate 910, having the rivet nut 920 press-riveted thereto, into the connecting hole 9101.

[0108] 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 1201, the clamping moving member 211 drives the pair of clamping fingers 221 of the clamping member 22 to move through the lifting drive member 212, and the pair of clamping fingers 221 are respectively located on both sides of the connection plate 910 in the press-riveting support space 1201, so as to clamp the connection plate 910 by the relative movement of the pair of clamping fingers 221, and After the holding fingers 221 clamp the connecting plate 910, the material clamping moving part 211 drives the pair of clamping fingers 221 of the clamping part 22 to move to a predetermined position above the conveying channel 51 through the lifting drive part 212, so that after the pair of clamping fingers 221 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 51, so that the connecting plate 910 with the rivet nut 920 riveted can be subsequently operated under the conveyance of the conveying channel 51.

[0109] Preferably, the press riveting device capable of automatically feeding nuts further includes a waste collector 60. The waste collector 60 includes at least one waste collector 60. The waste collector 60 is positioned along the path where the pair of clamping fingers 221 of the clamping member 22 are moved by the material clamping moving member 211 via the lifting drive 212. The waste collector 60 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 press-riveting the rivet nuts 920 in the connecting holes 9101.

[0110] 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 of the connecting plate 910 in the plate placement space 3101 is unqualified. At this time, a pair of the clamping fingers 221 will move relative to each other and clamp the connecting plate 910, so that after the clamping moving part 211 drives the pair of the clamping fingers 221 of the clamping part 22 to move above the waste collecting part 60 through the lifting drive part 212, the unqualified connecting plate 910 is placed in the waste collecting part 60 by moving the pair of the clamping fingers 221 away from each other.

[0111] 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 221 will move relative to each other and clamp the connecting plate 910, and after the clamping moving part 211 drives the pair of clamping fingers 221 of the clamping part 22 to move above the waste collecting part 60 through the lifting drive part 212, the connecting plate 910 with an unqualified placement position is placed in the waste collecting part 60 by moving the pair of clamping fingers 221 away from each other.

[0112] Specifically, the feeding mechanism 70 includes a receiving plate 71. The receiving plate 71 is located near the placement plate 31. A plurality of connecting plates 910 are placed on the receiving plate 71 in a stacked manner.

[0113] The suction mechanism 80 includes a material suction moving unit 81 and a plurality of material suction members 82. The material suction moving unit 81 is located between the material receiving plate 71 and the placement plate 31. The material suction members 82 are arranged on the material suction moving unit 81 in a manner that can press against and absorb one of the connecting plates 910 placed on the material receiving plate 71. The connecting plate 910 sucked by the material suction member 82 is moved to a predetermined position above the placement plate 31 by the material suction moving unit 81. In other words, after the material suction member 82 sucks the connecting plate 910, the material suction moving unit 81 can drive the material suction member 82 to move the connecting plate 910 sucked by the material suction member 82 to a predetermined position above the placement plate 31.

[0114] It is worth noting that since multiple connecting plates 910 are placed on the receiving plate 71 in a stacked manner, the suction member 82 can improve the consistency of the connecting plates 910, thereby improving the overall efficiency of the equipment. At the same time, the suction member 82 can absorb the connecting plates 910, which can reduce the fatigue caused by manual placement of the connecting plates 910 on the placement plate 31. This can prevent manual fatigue from reducing the speed of placing the connecting plates 910 on the placement plate 31, thereby preventing the impact on production efficiency.

[0115] Preferably, the feeding mechanism 70 further includes a plurality of positioning members 72, which are disposed parallel to each other on the receiving plate 71, and a material discharge space 701 for stacking the plurality of connecting plates 910 is formed between the plurality of positioning members 72 and the receiving plate 71. The plurality of positioning members 72 are used to prevent the connecting plates 910 from tilting as a whole when the connecting plates 910 are stacked and placed on the receiving plate 71, thereby ensuring that the suction member 82 can absorb the connecting plates 910.

[0116] Specifically, the material suction and movement unit 81 includes a material suction and movement member 811, a suction and transfer mounting member 812, and a material suction and drive member 813. The material suction and drive member 813 is mounted on the material suction and movement member 811 via the suction and transfer mounting member 812 so as to be movable between the material receiving plate 71 and the plate placement space 3101 of the placement plate 31.
