[0038] That is, on the path where the press-in member 112 is moved by the press-in driving member 111, the rivet nut 920, the upset portion 921 of the rivet nut 920, the connecting hole 9101 corresponding to the upset end 131, and the upset end 131 are sequentially arranged. The outer diameter of the rivet nut 920 is greater than the inner diameter of the connecting hole 9101, the outer diameter of the upset portion 921 is adapted to the inner diameter of the connecting hole 9101, and the rivet nut 920, the upset portion 921, the connecting hole 9101, and the upset end 131 are coaxial.

[0039] The nut feeding mechanism 20 includes a release assembly 21. The release assembly 21 includes a pair of release turnover members 211, a pair of release return members 212 corresponding to the release turnover members 211, and a release fixing member 213.

The release fixing member 213 is arranged on the press-in support table 12. The release turnover members 211 are movably arranged on the release fixing member 213 through the release return members 212, so that when the rivet nut 920 in the nut placement space 2101 is moved to the upset end 131 by the press-in member 112 driven by the press-in driving member 111, the release turnover members 211 are offset by deformation of the release return members 212, and the rivet nut 920 falls from the nut placement space 2101, and the upset portion 921 of the rivet nut 920 can smoothly pass through the connecting hole 9101 and abut against the upset end 131.

[0040] The nut feeding mechanism 20 further includes a nut supply member 22 and a guide unit 23.

[0041] Preferably, the nut supply member 22 is implemented to include a vibration disc. The nut supply member 22 is used to feed the rivet nut 920 with the downward upset portion 921 and feed the rivet nut 920 to the guide unit 23.

[0042] In the present embodiment, the guiding unit 23 comprises a first guiding nut member 231 forming a first delivery passage and a second guiding tube member 232 forming a second guiding passage. One end of the first delivery passage is communicated with the nut supplying member 22, and the other end of the first delivery passage corresponds to one end of the second guiding passage. The releasing fixture 213 has a guiding passage 2131 for passing the rivet nut 920, and forms a stop wall 2132 in the extension direction of the guiding passage 2131, and a stop space 21301 for parking the rivet nut 920 sliding through the guiding passage 2131 and hitting against the stop wall 2132 is formed between the stop wall 2132 and the guiding passage 2131.

The releasing assembly 21 further comprises a nut pushing member 214 arranged towards the stop space 21301 and the nut placing space 2101, and a pushing member 215 arranged on the nut pushing member 214 in a manner that it can pass through the stop space 21301 and move towards the nut placing space 2101.

[0043] It can be understood that, after the rivet nut 920 enters the first delivery passage with the upset portion 921 downwards, the rivet nut 920 will pass through the first delivery passage, the second guiding passage and the guiding passage 2131 in turn, and hit against the stop wall 2132 to park in the stop space 21301. At this time, the nut pushing member 214 will drive the pushing member 215 to move towards the nut placing space 2101, so as to push the rivet nut 920 parked in the stop space 21301 into the nut placing space 2101 through the pushing member 215 for subsequent operation.

[0044] In another variant embodiment, the releasing fixture 213 has a guiding passage 2131 for passing the rivet nut 920. The guiding unit 23 comprises a first guiding nut member 231 forming a first delivery passage and a second guiding tube member 232 forming a second guiding passage. One end of the first delivery passage is communicated with the nut supplying member 22, and the other end of the first delivery passage corresponds to one end of the second guiding passage. The other end of the second guiding passage is communicated with one end of the guiding passage 2131. The guiding passage 2131 is arranged towards the nut placing space 2101.

[0045] It can be understood that after the rivet nut 920 enters the first sending channel with the upset portion 921 facing downward, the rivet nut 920 will pass through the first sending channel, the second guide channel and the guide channel 2131 in sequence, and enter the nut placement space 2101 under the guidance of the guide channel 2131 to perform subsequent operations.

[0046] In order for those skilled in the art to understand the utility model, in at least one embodiment of the utility model, only the guide unit 23 includes the first guide nut member 231 and the second guide tube member 232, the first guide nut member 231 forms the first sending channel, the second guide tube member 232 forms the second guide channel, one end of the first sending channel is communicated with the nut supply member 22, the other end of the first sending channel corresponds to one end of the second guide channel, the release fixing member 213 has the guide channel 2131 for passing through the rivet nut 920 and forms the stop wall 2132, the stop wall 2132 is located in the extension direction of the guide channel 2131, and the stop wall 2132 and the guide channel 2131 form the stop space 21301 for parking the rivet nut 920 sliding through the guide channel 2131 and impacting on the stop wall 2132, the other end of the second guide channel is communicated with one end of the guide channel 2131 away from the stop space 21301, and the release assembly 21 further includes the nut pushing member 214 and the pushing member 215, the nut pushing member 214 is arranged towards the stop space 21301 and towards the nut placement space 2101, and the pushing member 215 is arranged on the nut pushing member 214 in a manner that can pass through the stop space 21301 and move towards the nut placement space 2101.

[0047] Preferably, the release restoring member 212 is implemented to include a torsion spring. The nut pushing member 214 is implemented to include a pneumatic cylinder.

[0048] In the embodiment, the guide unit 23 further includes at least one air pipe member 233. The air pipe member 233 is arranged to be communicated with one end of the second guide channel close to the first sending channel. When the rivet nut 920 enters the second guide channel, air is blown to the second guide channel through the air pipe member 233, so that the smoothness of the rivet nut 920 sliding through the second guide channel and the guide channel 2131 is improved, and the rivet nut 920 is prevented from being stuck in the inner wall of the second guide channel and the inner wall of the guide channel 2131 and unable to slide to the stop space 21301.

[0049] In another variant, the guiding unit 23 further comprises at least one air pipe 233. The air pipe 233 is arranged to communicate with the guiding passage 2131 near one end of the stop wall 2132. When the rivet nut 920 enters the second guiding passage, air is sucked into the guiding passage 2131 through the air pipe 233, thereby improving the smoothness of the rivet nut 920 sliding through the second guiding passage and the guiding passage 2131, and preventing the rivet nut 920 from being stuck in the inner wall of the second guiding passage and the inner wall of the guiding passage 2131 and unable to slide to the stop space 21301.

[0050] Preferably, the end of the second guiding passage near the first sending passage is higher than the end of the second guiding passage near the guiding passage 2131, so that after the rivet nut 920 enters the second guiding passage, it can slide into the guiding passage 2131 under the action of gravity.

[0051] Preferably, the extension direction of the first sending passage of the first guiding nut 231 is staggered with the extension direction of the second guiding passage of the second guiding pipe 232. The nut feeding mechanism 20 further comprises a passage adjusting mechanism 24. The passage adjusting mechanism 24 comprises a stagger driving member 241 and a stagger member 242. The stagger driving member 241 and the stagger member 242 are located between the first sending passage and the second guiding passage, and the stagger member 242 forms a communication space 24201. The communication space 24201 can be alternately communicated with the first sending passage and the second guiding passage when the stagger member 242 is driven by the stagger driving member 241. The communication space 24201 is adapted to the rivet nut 920.

[0052] As can be understood by a person skilled in the art, when multiple rivet nuts 920 are pushed into the first delivery channel of the first guide nut member 231, the stagger member 242 is driven by the stagger driving member 241 to make the communication space 24201 of the stagger member 242 communicate with the first delivery channel, at this time, the rivet nuts 920 in the first delivery channel close to the stagger driving member 241 are pushed into the communication space 24201 by other rivet nuts 920 in the first delivery channel, the stagger driving member 241 drives the stagger member 242 again to make the communication space 24201 of the stagger member 242 communicate with the second guide channel, the rivet nuts 920 slide into the second guide channel due to gravity, and in the process of blowing air into the second guide channel through the air pipe member 233, the rivet nuts 920 slide through the second guide channel and the guide channel 2131 and stop in the stop space 21301 after hitting the stop wall 2132, the rivet nuts 920 in the stop space 21301 are pushed into the nut placement space 2101 by the pushing member 215.

[0053] It is worth mentioning that due to the arrangement of the stagger driving member 241, a single rivet nut 920 can enter the second guide channel and the guide channel 2131 and stop in the stop space 21301 after hitting the stop wall 2132, so as to avoid multiple rivet nuts 920 entering the second guide channel and the guide channel 2131 at the same time, thereby avoiding the situation that the second guide channel cannot be smoothly blown due to being blocked by multiple rivet nuts 920 when air is blown into the second guide channel by the air pipe member 233, and preventing multiple rivet nuts 920 from being unable to enter the stop space 21301 due to being stuck in the second guide channel and the guide channel 2131.

[0054] Preferably, the stagger driving member 241 is implemented as a pneumatic cylinder.

[0055] Preferably, the nut delivery mechanism 20 further comprises a nut detection member 25, the nut detection member 25 is arranged near a pair of release flip members 211, and the nut detection member 25 faces the nut placement space 2101, so as to detect whether the rivet nut 920 is placed in the nut placement space 2101 through the nut detection member 25.

[0056] For example, when there is no rivet nut 920 in the nut placement space 2101, the guide channel 2131, the first delivery channel, the second guide channel and the stop space 21301 need to be checked to check the possibility that the rivet nut 920 is stuck in the guide channel 2131, the second guide channel and the stop space 21301.

[0057] Further, when the rivet nut 920 is stuck in the guide channel 2131, the second guide channel and the stop space 21301, the guide channel 2131, the second guide channel and the stop space 21301 need to be cleaned in time; when the rivet nut 920 is stuck in the guide channel 2131, the second guide channel and the stop space 21301, one rivet nut 920 needs to be sent into the second guide channel again, and the rivet nut 920 needs to be made to enter the stop space 21301 after sequentially passing through the second guide channel and the guide channel 2131 and hitting the stop wall 2132, so as to push the rivet nut 920 located in the stop space 21301 to the nut placement space 2101 by the nut pushing piece 214 driven by the pushing piece 215.

[0058] As a preferred, the nut detection piece 25 is implemented to include a laser sensor.

[0059] It can be understood that, the rivet portion 921 of the rivet nut 920 is towards the connecting hole 9101 corresponding to the riveting end 131, and after being driven by the riveting element 112 and passing through the connecting hole 9101 corresponding to the riveting end 131, the inner wall of the rivet portion 921 is pressed by the riveting end 131, and in the process of continuously pushing the rivet nut 920 by the riveting element 112, the rivet portion 921 is guided by the riveting end 131 and is folded along the radial direction of the riveting end 131 to rivet into the connecting plate 910, thereby riveting the rivet nut 920 as a whole at the connecting hole 9101 corresponding to the riveting end 131.

[0060] Preferably, the riveting assembly 11 further comprises a plurality of attracting pieces 113. The plurality of attracting pieces 113 are arranged at the contact position of the riveting element 112 and the rivet nut 920, and are used to adsorb the rivet nut 920 when the riveting element 112 drives the rivet nut 920 to move towards the riveting end 131, so that the rivet portion 921 of the rivet nut 920 can stably pass through the connecting hole 9101.

[0061] As a preferred, the attracting piece 113 is implemented to include a magnet.

[0062] Specifically, the riveting element 112 forms a nut fixing portion 1121 for passing through the nut hole 9201 of the rivet nut 920 at the riveting end 131. The outer diameter of the nut fixing portion 1121 is matched with the inner diameter of the nut hole 9201.

[0063] As an example, when the pressure riveting member 112 moves towards the flip riveting end 131, the nut fixing portion 1121 will pass through the nut hole 9201, and the plurality of suction members 113 will suck the riveting nut 920, so that the riveting nut 920 can be driven by the pressure riveting member 112 to pass through the connecting hole 9101.

[0064] Preferably, the pressure riveting mechanism 10 further comprises a positioning assembly 14. The positioning assembly 14 comprises a rebounding rod 141 and a positioning rebounding member 142. The flip riveting member 13 is axially formed with a positioning accommodation space 1301. The rebounding rod 141 is coaxially arranged in the positioning accommodation space 1301 with the flip riveting end 131. The rebounding rod 141 has a penetrating end 1411 coaxial with the flip riveting end 131 and extending into the positioning accommodation space 1301, and the penetrating end 1411 matches the inner diameter of the connecting hole 9101, so as to pass through the connecting hole 9101 to stabilize the connecting plate 910 when the connecting plate 910 is placed in the pressure riveting support space 1201 with the connecting hole 9101 corresponding to the flip riveting end 131. The positioning rebounding member 142 is arranged between the end of the rebounding rod 141 away from the penetrating end 1411 and the inner wall of the positioning accommodation space 1301, and the positioning rebounding member 142 is used to realize the reciprocating movement of the rebounding rod 141 in the axial direction of the positioning accommodation space 1301.

[0065] As can be understood by those skilled in the art, after the connecting plate 910 is placed in the pressure riveting support space 1201 with the connecting hole 9101 corresponding to the flip riveting end 131, the penetrating 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 riveting nut 920 will be inserted by the nut fixing portion 1121 when the pressure riveting member 112 pushes the riveting nut 920, and the flip riveting portion 921 will push the penetrating end 1411 into the pressure riveting support space 1201 during the process of entering the connecting hole 9101, and the positioning rebounding member 142 will be compressed and deformed. After the flip riveting portion 921 of the riveting nut 920 completely passes through the connecting hole 9101 and abuts against the flip riveting end 131, during the process of continuously pushing the riveting nut 920 by the pressure riveting member 112, the flip riveting portion 921 will be guided by the flip riveting end 131 and folded along the radial direction of the flip riveting end 131 to rivet into the connecting plate 910, thereby integrally pressure riveting the riveting nut 920 at the connecting hole 9101 corresponding to the flip riveting end 131.

[0066] Preferably, the press-in mechanism 10 further comprises a displacement sensor 15. The displacement sensor 15 is arranged towards a portion of the press-in member 112, and is configured to detect a displacement distance of the press-in member 112 when the press-in member 112 is driven by the press-in driving member 111. In this way, when the press-in member 112 is driven by the press-in driving member 111 and moves the rivet nut 920 towards the position of the clinch end 131, the displacement distance of the press-in member 112 is detected to determine whether the clinch portion 921 of the rivet nut 920 has penetrated the connection hole 9101.

[0067] For example, in one aspect, when the displacement sensor 15 detects that the displacement distance of the press-in member 112 when driven by the press-in driving member 111 is less than a predetermined value, it indicates that the clinch portion 921 of the rivet nut 920 has not penetrated the connection hole 9101, and the press-in operation is not qualified. In this case, manual inspection is required to determine whether there is a mechanical failure. In another aspect, when the displacement sensor 15 detects that the displacement distance of the press-in member 112 when driven by the press-in driving member 111 is greater than a predetermined value, it indicates that the press-in member 112 and the clinch end 131 can not be placed with the rivet nut 920, or the press-in member 112 is excessively pressed into the connection hole 9101 of the connection plate 910, and the press-in operation is not qualified. In this case, manual inspection is required to determine whether there is a mechanical failure.

[0068] It should be noted that when the press-in member 112 continuously pushes the rivet nut 920, and the clinch portion 921 is guided by the clinch end 131 and is folded along the radial direction of the clinch end 131 to be riveted into the connection plate 910, the pressure applied by the press-in member 112 to the rivet nut 920 needs to be a predetermined value to ensure that the rivet nut 920 is riveted as a whole at the connection hole 9101 corresponding to the clinch end 131. The press-in member 112 further presses the rivet nut 920 as a whole at the connection hole 9101 corresponding to the clinch end 131.

[0069] Preferably, the press-in mechanism 10 further comprises a pressure sensor 16. The pressure sensor 16 is arranged on the press-in member 112, and is configured to detect the pressure applied by the press-in member 112 to the rivet nut 920 to ensure that after the clinch portion 921 of the rivet nut 920 penetrates the connection hole 9101 corresponding to the clinch end 131, the rivet nut 920 can be riveted as a whole at the connection hole 9101 of the connection plate 910.

[0070] The skilled in the art can understand that when the pressure sensor 16 detects that the pressure applied by the pressure rivet 112 to the rivet nut 920 does not match the predetermined value, it indicates that the operation of the rivet nut 920 being pressure riveted to the connecting hole 9101 of the connecting plate 910 is unqualified.

[0071] Preferably, the pressure riveting device capable of automatically feeding the nut further comprises a placing mechanism 30 and a clamping shifting mechanism 40.

[0072] Specifically, the placing mechanism 30 comprises a placing plate 31. The placing plate 31 is located near the pressure riveting support table 12. The placing plate 31 forms a placing plate space 3101 which is adapted to the connecting plate 910. The placing plate space 3101 is used for placing the connecting plate 910.

[0073] The clamping shifting mechanism 40 comprises a clamping shifting driving unit 41 and a clamping piece 42. The clamping piece 42 is arranged on the clamping shifting driving unit 41 in a movable manner between the placing plate 31 and the pressure riveting support table 12, and the clamping piece 42 has a pair of clamping fingers 421 which can move relatively and oppositely. A pair of the clamping fingers 421 are used for clamping the connecting plate 910 from the placing plate space 3101, and releasing the connecting plate 910 to the pressure riveting support space 1201 in a manner that the connecting hole 9101 corresponds to the pressure riveting end 131 after being moved to the pressure riveting support table 12 by the clamping shifting driving unit 41, while making the penetrating end 1411 enter the connecting hole 9101 for subsequent operation.

[0074] As an example, after the connecting plate 910 is placed in the placing plate space 3101 by manual operation, the clamping piece 42 can be driven by the clamping shifting driving unit 41 and close to the connecting plate 910 in the placing plate space 3101, and then a pair of the clamping fingers 421 can clamp the connecting plate 910 in the placing plate space 3101 by relative movement, and after the connecting plate 910 clamped by a pair of the clamping fingers 421 is moved above the pressure riveting support table 12 by the clamping shifting driving unit 41, the connecting plate 910 is released to the pressure riveting support space 1201 in a manner that the connecting hole 9101 corresponds to the pressure riveting end 131 by opposite movement of a pair of the clamping fingers 421, so as to pressure rivet the rivet nut 920 to the connecting hole 9101 corresponding to the pressure riveting end 131.

[0075] Further, after one of the rivet nuts 920 is pressed in the connection hole 9101 corresponding to the flange riveting end 131, the connection plate 910 can be clamped again by a pair of the clamping fingers 421, and under the driving of the material clamping and shifting driving unit 41, the connection plate 910 clamped by the pair of the clamping fingers 421 is placed in the rivet pressing support space 1201 of the rivet pressing support table 12 in a manner that another connection hole 9101 of the connection plate 910 corresponds to the flange riveting end 131, so as to continue to press another rivet nut 920 in another connection hole 9101 corresponding to the flange riveting end 131. In this way, the rivet nuts 920 are pressed in each of the connection holes 9101 of the connection plate 910.

[0076] Preferably, the clamping fingers 421 are implemented to include pneumatic fingers.

[0077] It is worth mentioning that, compared with the operation of placing the connection plate 910 in the rivet pressing support space 1201 by hand, the connection plate 910 is clamped and released to the rivet pressing support space 1201 by a pair of the clamping fingers 421, which can avoid the hands close to the rivet pressing support table 12 from being pressed and injured when the rivet pressing piece 112 is driven by the rivet pressing driving piece 111, thereby providing protection for the safety of workers.

[0078] As a preference, the connection line of each of the connection holes 9101 of the connection plate 910 is parallel to the direction in which the material clamping and shifting driving unit 41 drives the clamping piece 42 to move, so as to ensure that the material clamping and shifting driving unit 41 can drive each of the connection holes 9101 to be placed in the rivet pressing support space 1201 in a manner that the connection hole 9101 corresponds to the flange riveting end 131 under the driving of a pair of the clamping fingers 421 of the clamping piece 42.

[0079] Preferably, the rivet pressing driving piece 111 is implemented to include a gas-liquid booster cylinder.

[0080] In the embodiment, the placing mechanism 30 further includes a pushing assembly 32. The pushing assembly 32 includes a shifting driving piece 321 and at least one shifting guide piece 322. The placing plate 31 is fitted in the shifting guide piece 322 in a manner that the placing plate 31 can move along the extension direction of the shifting guide piece 322 to approach or move away from a pair of the clamping fingers 421. The placing plate 31 is arranged at the output end of the shifting driving piece 321, so that when the connection plate 910 is placed in the placing plate space 3101, the shifting driving piece 321 drives the placing plate 31 to move along the extension direction of the shifting guide piece 322 and approach a pair of the clamping fingers 421, so as to facilitate a pair of the clamping fingers 421 to clamp the connection plate 910 in the placing plate space 3101.

[0081] The clamp material shifting driving unit 41 comprises a clamp material moving member 411 and a lifting driving member 412. The clamp material moving member 411 is located between the placement plate 31 and the rivet support table 12. The clamp member 42 is arranged on the clamp material moving member 411 in a manner that it can move between the placement plate 31 and the rivet support table 12 through the lifting driving member 412.

[0082] As an example, the shifting driving member 321 drives the placement plate 31 to move along the extension direction of the shifting guide 322 and approach a pair of the clamping fingers 421, and after a pair of the clamping fingers 421 move relatively to clamp the connecting plate 910 in the placement space 3101, the lifting driving member 412 drives the connecting plate 910 clamped by a pair of the clamping fingers 421 of the clamp member 42 to lift off the placement plate 31, and the clamp material moving member 411 drives the connecting plate 910 clamped by a pair of the clamping fingers 421 to move to the rivet support table 12 through the lifting driving member 412.

[0083] Further, after the clamp material moving member 411 drives the connecting plate 910 clamped by a pair of the clamping fingers 421 to move above the rivet support table 12 through the lifting driving member 412, and one of the connecting holes 9101 of the connecting plate 910 corresponds to the rivet end 131 of the rivet member 13, the lifting driving member 412 drives the connecting plate 910 clamped by a pair of the clamping fingers 421 to approach the rivet support table 12 and enter the rivet support space 1201, at this time, a pair of the clamping fingers 421 move away to release the connecting plate 910 to the rivet support space 1201 in a manner that one of the connecting holes 9101 corresponds to the rivet end 131. Further, in the process that the rivet member 112 moves and drives the rivet nut 920 to move to the rivet end 131, the riveting part 921 of the rivet nut 920 penetrates through the connecting hole 9101 corresponding to the rivet end 131 and abuts against the rivet end 131, and in the process that the rivet member 112 continuously drives the rivet nut 920, the rivet nut 920 is riveted to the connecting hole 9101 of the connecting plate 910 in a manner that the riveting part 921 of the rivet nut 920 is riveted along the radial direction.

[0084] Among them, after the lifting driving member 412 drives the connecting plate 910 clamped by a pair of the clamping fingers 421 of the clamp member 42 to lift off the placement plate 31, in the process that the clamp material 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 driving member 412, the connecting plate 910 is prevented from falling off from a pair of the clamping fingers 421 due to the mistake of colliding with the placement plate 31.

[0085] Preferably, the lifting drive 412 and the pushing assembly 32 are both implemented as a pneumatic cylinder. The material clamping moving member 411 is implemented as an electric cylinder.

[0086] In another variant, the material clamping displacement drive unit 41 comprises a material clamping moving member 411, a lifting drive 412 and a telescopic drive 413. The material clamping moving member 411 is located between the placement plate 31 and the rivet pressing support table 12. The telescopic drive 413 is arranged on the material clamping moving member 411 through the lifting drive 412 in a manner that it is movable between the placement plate 31 and the rivet pressing support table 12. The clamping member 42 is arranged on the telescopic drive 413, so that when the material clamping moving member 411 drives the telescopic drive 413 to move to the vicinity of the placement plate 31 through the lifting drive 412, a pair of the clamping fingers 421 of the clamping member 42 can be sent to both sides of the connecting plate 910 in the placement space 3101 through the telescopic drive 413, so as to clamp the connecting plate 910 in the placement space 3101 through the relative movement of a pair of the clamping fingers 421.

[0087] As an example, after the relative movement and clamping of a pair of the clamping fingers 421 to the connecting plate 910 in the placement space 3101, the lifting drive 412 drives the connecting plate 910 clamped by a pair of the clamping fingers 421 of the clamping member 42 to lift away from the placement plate 31 through the telescopic drive 413, and the telescopic drive 413 drives the connecting plate 910 clamped by a pair of the clamping fingers 421 away from the placement plate 31, so as to prevent the connecting plate 910 from falling off from between a pair of the clamping fingers 421 due to the collision with the placement plate 31 during the movement of the connecting plate 910 clamped by a pair of the clamping fingers 421 to the rivet pressing support table 12 through the material clamping moving member 411, the lifting drive 412 and the telescopic drive 413.

[0088] Further, after the telescopic drive 413 drives the connecting plate 910 held by the pair of clamping fingers 421 away from the placement plate 31, the material clamping moving member 411 drives the connecting plate 910 held by the pair of clamping fingers 421 to above the rivet pressing support table 12 through the lifting drive 412 and the telescopic drive 413, and makes one connecting hole 9101 of the connecting plate 910 correspond to the rivet end 131 of the rivet pressing member 13. The lifting drive 412 drives the connecting plate 910 held by the pair of clamping fingers 421 to approach the rivet pressing support table 12 and enter the rivet pressing support space 1201 through the telescopic drive 413, at this time, the pair of clamping fingers 421 move away from each other to release the connecting plate 910 to the rivet pressing support space 1201 in a manner that one connecting hole 9101 corresponds to the rivet end 131. In the process that the rivet pressing member 112 moves and drives the rivet nut 920 to the rivet end 131, the rivet end 131 of the rivet nut 920 passes through the connecting hole 9101 corresponding to the rivet end 131 and abuts against the rivet end 131, and in the process that the rivet pressing member 112 continuously drives the rivet nut 920, the rivet nut 920 is riveted to the connecting hole 9101 of the connecting plate 910 in a manner that the rivet end 131 is riveted along the radial direction.

[0089] Preferably, the lifting drive 412 and the telescopic drive 413 are both implemented as a pneumatic cylinder. The material clamping moving member 411 is implemented as an electric cylinder. The pushing assembly 32 is implemented as a pneumatic cylinder.

[0090] In order for those skilled in the art to understand the present application, in at least one embodiment of the present application, only the placement mechanism 30 further comprises the pushing assembly 32, the pushing assembly 32 comprises the displacement drive 321 and at least one displacement guide 322, the placement plate 31 is embedded in the displacement guide 322 in a manner that it can move along the extension direction of the displacement guide 322 and approach the pair of clamping fingers 421, the placement plate 31 is arranged at the output end of the displacement drive 321, the material clamping moving member 411 and the material clamping displacement drive unit 41, the material clamping moving member 411 is located between the placement plate 31 and the rivet pressing support table 12, and the clamping member 42 is arranged on the material clamping moving member 411 through the lifting drive 412 in a manner that it can move between the placement plate 31 and the rivet pressing support table 12.

[0091] It should be noted that the connecting hole 9101 of the connecting plate 910 corresponding to the riveting end 131 is pressed riveted with the rivet nut 920, and a pair of clamping fingers 421 will clamp the connecting plate 910, and the connecting plate 910 will be lifted away from the rivet pressing support table 12 by the lifting drive 412. At this time, the rebound rod 141 will be pushed back to the position coaxial with the riveting end 131 and extending into the positioning and containing space 1301 under the action of the positioning and rebounding element 142, so as to enter another connecting hole 9101 of the connecting plate 910 or the connecting hole 9101 of the next connecting plate 910.

[0092] It should be noted that the front surface 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, the rivet nut 920 needs to protrude from the back surface of the connecting plate 910 without an identification code after being pressed riveted on the connecting plate 910, so as to facilitate the maintenance personnel to check the model of the damaged energy absorption box through the identification code, and then facilitate maintenance and replacement. In this scheme, the back surface of the connecting plate 910 without an identification code is upward, so that when the connecting plate 910 in the plate placing space 3101 is clamped by a pair of clamping fingers 421 and moved to the rivet pressing support space 1201, and the rivet nut 920 is pressed riveted on the connecting plate 910, the rivet nut 920 can protrude from the back surface of the connecting plate 910 without an identification code.

[0093] Preferably, the placing mechanism 30 further comprises a photographing and detecting element 33. The photographing and detecting element 33 is arranged to face the connecting plate 910 placed in the plate placing space 3101, and there is a predetermined distance between the photographing and detecting element 33 and the placing plate 31. The photographing and detecting element 33 is used to photograph and detect the surface of the connecting plate 910 when the connecting plate 910 is placed in the plate placing space 3101.

[0094] As a preferred embodiment, the photographing and detecting element 33 is implemented by a charge-coupled device.

[0095] Preferably, the photographing and detecting element 33 is arranged to face the lower surface of the connecting plate 910 in the plate placing space 3101.

[0096] As an example, when the photographing and detecting element 33 detects that the surface of the connecting plate 910 has an identification code, it means that the connecting plate 910 is placed correctly, which indicates that a pair of clamping fingers 421 can clamp the connecting plate 910 into the rivet pressing support space 1201, and the rivet nut 920 can be pressed riveted on the connecting hole 9101 of the connecting plate 910.

[0097] Further, when the shooting detection piece 33 detects that the surface of the connecting plate 910 has no identification code, it represents that the connecting plate 910 is placed incorrectly, which means that after the pair of clamping fingers 421 take out the connecting plate 910 from the plate placing space 3101, the connecting plate 910 cannot be clamped into the rivet supporting space 1201 for subsequent operation until the next connecting plate 910 is placed in the plate placing space 3101 with the reverse surface facing upward.

[0098] As a preferred, when the connecting plate 910 in the plate placing space 3101 is placed incorrectly, the pair of clamping fingers 421 can clamp the connecting plate 910 and flip it over to make the connecting plate 910 with the reverse surface facing upward, and then place the connecting plate 910 with the reverse surface facing upward in the rivet supporting space 1201 for subsequent operation.

[0099] In this embodiment, the placing mechanism 30 further comprises a through hole piece 34 corresponding to the connecting hole 9101 of the connecting plate 910, which is used to be inserted into the connecting hole 9101 of the connecting plate 910 placed in the plate placing space 3101, and then fix the position of the connecting plate 910 in the plate placing space 3101 through the through hole piece 34.

[0100] It is worth mentioning that after the lifting driving piece 412 drives the pair of clamping fingers 421 of the clamping piece 42 to lift the connecting plate 910 away from the placing plate 31, the through hole piece 34 can be separated from the connecting hole 9101, so as to avoid that the connecting plate 910 is blocked by the through hole piece 34 when the clamping moving piece 411 moves the connecting plate 910 clamped by the pair of clamping fingers 421 away from the placing plate 31.

[0101] As a preferred, the outer diameter of the through hole piece 34 gradually decreases from the position close to the placing plate 31 to the position away from the placing plate 31, and the outer diameter of the through hole piece 34 close to the placing plate 31 is adapted to the inner diameter of the connecting hole 9101, so as to improve the smoothness when the through hole piece 34 is inserted into the connecting hole 9101, and the connecting plate 910 in the plate placing space 3101 can be fixed smoothly.

[0102] It should be noted that due to the influence of production process, the inner diameter of the connecting hole 9101 of the connecting plate 910 may be smaller than the outer diameter of the rivet nut 920, at this time the rivet nut 920 cannot pass through the connecting hole 9101, and then the rivet nut 920 cannot be riveted to the connecting plate 910.

[0103] The skilled in the art can understand that, as the outer diameter of the perforating member 34 gradually decreases from the position close to the placement plate 31 to the position far from the placement plate 31, when the connecting plate 910 is placed in the placement space 3101 and each perforating member 34 penetrates into the corresponding connecting hole 9101, the inner diameter of one connecting hole 9101 not meeting the requirements will cause the connecting plate 910 to be overall skewed. By shooting the surface identification code of the connecting plate 910 by the shooting detection member 33, whether the inner diameter of the connecting hole 9101 of the connecting plate 910 meets the requirements can be determined.

[0104] For example, when the shooting detection member 33 shoots and recognizes that the surface identification code of the connecting plate 910 in the placement space 3101 is overall skewed, it indicates that the inner diameter of the connecting hole 9101 does not meet the requirements, i.e., the connecting plate 910 is unqualified, and one pair of the clamping fingers 421 cannot clamp the connecting plate 910 to the press-in support space 1201 for subsequent operation. When the shooting detection member 33 shoots and recognizes that the surface identification code of the connecting plate 910 in the placement space 3101 is overall flat, it indicates that the inner diameter of the connecting hole 9101 meets the requirements, and one pair of the clamping fingers 421 can clamp the connecting plate 910 to the press-in support space 1201 for subsequent operation.

[0105] In the embodiment, the press-in equipment capable of automatically feeding nuts further comprises a discharging conveying mechanism 50. The discharging conveying mechanism 50 is arranged on the path through which the clamping moving member 411 moves the pair of clamping fingers 421 of the clamping member 42 driven by the lifting driving member 412. The discharging conveying mechanism 50 forms a conveying passage 51. The conveying passage 51 is used for conveying the connecting plate 910 in which the rivet nut 920 is press-in riveted.

[0106] As can be understood by a person skilled in the art, after the rivet nut 920 is riveted in each connecting hole 9101 of the connecting plate 910 in the riveting support space 1201, the material clamping moving member 411 drives the pair of clamping fingers 421 of the clamping member 42 to move by the lifting driving member 412, and the pair of clamping fingers 421 are respectively located on both sides of the connecting plate 910 in the riveting support space 1201, so as to clamp the connecting plate 910 by the relative movement of the pair of clamping fingers 421, and after the pair of clamping fingers 421 clamps the connecting plate 910, the material clamping moving member 411 drives the pair of clamping fingers 421 of the clamping member 42 to move to a predetermined position above the conveying channel 51 by the lifting driving member 412, so as to place the connecting plate 910 with the rivet nut 920 riveted in each connecting hole 9101 on the conveying channel 51 after the pair of clamping fingers 421 moves away from each other, so as to perform subsequent operations on the connecting plate 910 with the rivet nut 920 riveted by the conveying of the conveying channel 51.

[0107] Preferably, the riveting equipment capable of automatically feeding a nut further comprises a waste collecting member 60. The waste collecting member 60 comprises at least one waste collecting member 60. The waste collecting member 60 is arranged on the path of the material clamping moving member 411 driving the pair of clamping fingers 421 of the clamping member 42 to move by the lifting driving member 412. The waste collecting member 60 is used for placing the connecting plate 910 with an unqualified inner diameter of the connecting hole 9101 and the connecting plate 910 with an unqualified riveting of the rivet nut 920 in the connecting hole 9101.

[0108] As can be understood by a person skilled in the art, in one aspect, when the surface of the connecting plate 910 is detected as no identification code by the shooting detection member 33, it indicates that the placement of the connecting plate 910 in the plate placing space 3101 is unqualified, at this time, the pair of clamping fingers 421 will move relatively and clamp the connecting plate 910, so as to place the unqualified connecting plate 910 into the waste collecting member 60 by the relative movement of the pair of clamping fingers 421 after the material clamping moving member 411 drives the pair of clamping fingers 421 of the clamping member 42 to move above the waste collecting member 60 by the lifting driving member 412.

[0109] When the rivet nut 920 at the connecting hole 9101 of the connecting plate 910 is not qualified in the press riveting or the inner diameter of the connecting hole 9101 is not qualified, the pair of clamping fingers 421 will move oppositely to clamp the connecting plate 910, and after the clamping member 42 is moved to above the waste collecting member 60 by the lifting driving member 412, the unqualified connecting plate 910 is placed in the waste collecting member 60 by moving the pair of clamping fingers 421 oppositely.

[0110] Preferably, the automatic nut feeding press riveting device further comprises a feeding mechanism 70 and a suction moving mechanism 80.

[0111] Specifically, the feeding mechanism 70 comprises a material receiving plate 71. The material receiving plate 71 is located near the placing plate 31. A plurality of connecting plates 910 are placed on the material receiving plate 71 in a stacked manner.

[0112] The suction moving mechanism 80 comprises a suction moving unit 81 and a plurality of suction members 82. The suction moving unit 81 is located between the material receiving plate 71 and the placing plate 31. The suction members 82 are arranged on the suction moving unit 81 in a manner of being able to adhere to and suck one of the connecting plates 910 placed on the material receiving plate 71, and the suction moving unit 81 moves the connecting plate 910 sucked by the suction members 82 to a predetermined position above the placing plate 31. That is, after the suction members 82 suck the connecting plate 910, the suction moving unit 81 moves the connecting plate 910 sucked by the suction members 82 to a predetermined position above the placing plate 31 by driving the suction members 82.

[0113] It is worth mentioning that since a plurality of connecting plates 910 are placed on the material receiving plate 71 in a stacked manner, the continuity of the suction members 82 sucking the connecting plates 910 can be improved, thereby improving the overall efficiency of the device. At the same time, by sucking the connecting plates 910 by the suction members 82, the fatigue caused by manually placing the connecting plates 910 on the placing plate 31 multiple times can be reduced, thereby avoiding the situation that the speed of placing the connecting plates 910 on the placing plate 31 is reduced due to fatigue of the workers, so as to avoid affecting the production efficiency.

[0114] Preferably, the feeding mechanism 70 further comprises a plurality of positioning members 72, which are arranged on the material receiving plate 71 in parallel to each other and form a material placing space 701 between the positioning members 72 and the material receiving plate 71 for stacking the connecting plates 910. The positioning members 72 are used to prevent the connecting plates 910 from tilting as a whole and causing at least one of the connecting plates 910 to fall off when the connecting plates 910 are stacked on the material receiving plate 71, thereby ensuring the safety of the material suction member 82 in sucking the connecting plates 910.

[0115] In particular, the material suction moving unit 81 comprises a material suction moving member 811, a suction installation member 812 and a material suction driving member 813. The material suction driving member 813 is arranged on the material suction moving member 811 through the suction installation member 812 in a manner that it can move between the material receiving plate 71 and the placing space 3101 of the placing plate 31. The material suction member 82 is arranged on the material suction driving member 813 in a manner that it can be driven by the material suction driving member 813 and press against and suck the connecting plates 910 placed on the material receiving plate 71.

[0116] For example, when the material suction member 82 sucks the connecting plates 910 and is moved above the placing plate 31 by the material suction moving member 811 through the material suction driving member 813 and the suction installation member 812, and the connecting holes 9101 correspond to the perforated member 34, the material suction member 82 and the connecting plates 910 can be first driven by the material suction driving member 813 to approach the placing space 3101, and then the connecting plates 910 are placed in the placing space 3101 while the perforated member 34 passes through the connecting holes 9101 of the connecting plates 910.

[0117] Preferably, the material suction moving member 811 is implemented by an electric cylinder. The material suction driving member 813 is implemented by a pneumatic cylinder.

[0118] Preferably, the material suction member 82 forms a suction area 8201 and a gas supply channel 8202 connected to the suction area 8201. The suction area 8201 is formed at the position of the material suction member 82 when it is driven by the material suction driving member 813 and presses against the connecting plates 910, and the gas supply channel 8202 is used to supply gas to the suction area 8201 and suck air.

[0119] As an example, when the suction member 82 is driven by the suction driving member 813 and pressed against the connecting plate 910, the gas in the suction area 8201 can be sucked through the gas supply channel 8202, so that the connecting plate 910 can be sucked by the suction member 82. Further, when the suction member 82 is driven by the suction driving member 813 and the suction mounting member 812 to move to above the placement plate 31 by the suction moving member 811, and the connecting hole 9101 corresponds to the perforated member 34, the suction area 8201 can be filled with gas through the gas supply channel 8202, so that the connecting plate 910 sucked by the suction member 82 falls to the placement space 3101.

[0120] It should be noted that during the process of sucking the gas in the suction area 8201 through the gas supply channel 8202, the outside of the suction area 8201 of the suction member 82 can form a negative pressure, so that the connecting plate 910 can be adsorbed and sucked.

[0121] Preferably, the suction member 82 is implemented to include a suction disc.
