[0002] During the manufacturing process of the energy absorption box of the automobile anti-collision beam, the riveting device can press the nuts into the riveting holes on the back of the sheet material used to connect to the energy absorption box product according to the riveting standards. However, before pressing the nuts, the existing riveting device usually requires manual confirmation of the front and back sides of the connecting sheet material, and places the confirmed connecting sheet material on the press table with the back side facing up, waiting for the riveting device to press the nuts.

[0003] However, during the entire riveting process, the riveting device needs to continuously press nuts on a considerable number of connected sheets. This means that workers need to repeatedly perform the steps of confirming the front and back of the connected sheets and placing them on the press table. This requires a high degree of manual intervention, resulting in a low overall efficiency of press-fitting nuts. In addition, there is a low probability of manual operation errors, such as not placing some connected sheets on the press table with the back side facing up, which makes it difficult for the riveted connected sheets to meet the riveting standards.

The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0030] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0031] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0032] refer to Figures 1 to 11 According to a preferred embodiment of the present invention, an automatic nut riveting device will be described in detail below. The automatic nut riveting device can automatically detect an identification code on a sheet 91 and perform a riveting operation on the sheet 91 after detecting the identification code. The automatic nut riveting device includes an equipment body 10, a detection component 20, a feeding device 30 and a riveting component 40.

[0033] It should be noted that an identification code is set on the front of the sheet 91, and the detection component 20 can determine the placement of each sheet 91 by detecting the identification code, that is, whether the currently detected surface of the sheet 91 is the front or back.

[0034] The detection assembly 20 is disposed on the device body 10. The blanking device 30 can transport the sheet material 91, which has been inspected by the detection assembly 20 and has the front side thereof, to the riveting assembly 40. The riveting assembly 40 is configured to perform a riveting operation on the sheet material 91, which has been transported by the blanking device 30 and has the front side thereof.

[0035] Specifically, the detection assembly 20 includes a loading platform 21, a support frame 22, and a detection member 23. The loading platform 21 is connected to the support frame 22 and further defines a placement slot 2101 for placing the sheet material 91. The support frame 22 is connected to the device body 10. The detection member 23 is disposed at a predetermined vertical distance from the loading platform 21 and corresponds to the placement slot 2101 to detect the identification code on the sheet material 91.

[0036] Those skilled in the art can understand that when the sheet material 91 is placed in the placement slot 2101 of the loading platform 21, the front or back side of the sheet material 91 faces the detection component 23. At this time, the detection component 23 detects whether there is an identification code on the side of the sheet material 91 facing the detection component 23, and then determines whether the sheet material 91 is placed in a placement position with the front side facing up or with the back side facing up. Therefore, when the detection component 23 determines that the placement position of the sheet material 91 is with the back side facing up, the unloading device 30 can transport the sheet material 91 with the back side facing up to the riveting assembly 40.

[0037] In this way, the detection component 20 can automatically identify the front and back sides of the sheet material 91 instead of manually, thereby reducing manual intervention and improving the efficiency of the overall riveting of the sheet material 91. In addition, the detection component 20 can detect the sheet material 91 whose placement posture meets the riveting standard for the unloading device 30 to transport it to the riveting component 40, so that the sheet material 91 can be riveted according to the riveting standard.

[0038] In a preferred embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, the loading platform 21 is provided on the bottom wall of the placement slot 2101 to form an observation window 2102 in communication with the placement slot 2101. The support frame 22 is formed with an opening 2201 at a position near the observation window 2102 that is at least the same size as the observation window 2102. The opening 2201 is in communication with the outside world and is opposite to the observation window 2102. The detection member 23 is connected to the support frame 22 and is maintained below the loading platform 21 and facing the opening 2201, so as to detect the sheet material 91 in the placement slot 2101 from below the loading platform 21.

[0039] In a modified embodiment, the detection component 23 is connected to the support frame 22, and the detection component 23 is maintained above the loading platform 21 to detect the sheet material 91 located in the placement groove 2101 from above the loading platform 21.

[0040] Preferably, the inner wall forming the placement groove 2101 is configured to be at least partially missing, so as to form a notch 2103 at the side end of the loading platform 21 that is connected to the placement groove 2101, allowing the unloading device 30 to transport the sheet material 91. It is understandable that the projections of the sheet material 91 placed in the placement groove 2101 and the loading platform 21 on the same surface at least partially do not overlap, that is, the portion of the sheet material 91 located in the notch 2103, and the unloading device 30 can act on the portion of the sheet material 91 located in the notch 2103 to transport the sheet material 91.

[0041] Preferably, the loading platform 21 is provided with two positioning portions 211 on the bottom wall of the placement groove 2101. The two positioning portions 211 are arranged opposite to each other and spaced apart, and each positioning portion 211 is configured to pass through a riveting hole of the sheet material 91, so that the sheet material 91 can be stably placed in the placement groove 2101. It is worth mentioning that the outer diameter of the positioning portion 211 can be set according to the riveting standard, that is, the sheet material 91 passed through by the positioning portion 211 and whose inner diameter of the riveting hole matches the outer diameter of the positioning portion 211 meets the conditions for riveting, thereby screening the sheet materials 91 that can be riveted.

[0042] Preferably, the detection component 23 is implemented as a CCD camera for taking photos and identifying images.

[0043] The blanking device 30 includes a clamping assembly 31 and a moving assembly 32, wherein the clamping assembly 31 is used to clamp the sheet material 91. The moving assembly 32 can drive the clamping assembly 31 to approach the sheet material 91 located in the placement groove 2101, and after the clamping assembly 31 clamps the sheet material 91, the moving assembly 32 transports the sheet material 91 clamped by the clamping assembly 31 to the riveting assembly 40.

[0044] Specifically, if Figure 5 As shown, the clamping assembly 31 includes a pair of clamping arms 311 and a clamping drive member 312, wherein the two clamping arms 311 are connected to the output end of the clamping drive member 312 in an opposed and spaced relationship to form a clamping opening 3101. The clamping drive member 312 is provided in the material moving assembly 32, and is configured to drive the two clamping arms 311 to move relative to each other to adjust the size of the clamping opening 3101, so that the size of the clamping opening 3101 is adapted to the size of the sheet material 91, thereby enabling the sheet material 91 to be clamped.

[0045] Preferably, the clamping driving member 312 is implemented as a pneumatic finger cylinder.

[0046] In a modified embodiment, the material clamping assembly 31 includes a pair of clamping arms 311 and a material clamping drive member 312, wherein the two clamping arms 311 are arranged relative to and spaced apart to form a clamping opening 3101, and one of the clamping arms 311 is movably connected to the output end of the material clamping drive member 312. The material clamping drive member 312 is provided in the material moving assembly 32, and is configured to drive one of the clamping arms 311 to move relatively closer to and away from the other clamping arm 311, so that the size of the clamping opening 3101 is adapted to the size of the sheet material 91, so that the sheet material 91 can be clamped by the material clamping assembly 31. It is worth mentioning that in this embodiment, the material clamping drive member 312 is implemented as a telescopic cylinder.

[0047] In another variant embodiment, the clamping assembly 31 includes a pair of clamping arms 311 and the same number of clamping drive members 312 as the clamping arms 311, wherein the two clamping arms 311 are arranged relative to each other and spaced apart to form a clamping opening 3101, and each clamping arm 311 is movably connected to the output end of one of the clamping drive members 312. Both of the clamping drive members 312 are arranged in the material moving assembly 32, and then when the two clamping drive members 312 are started, the two clamping arms 311 can move closer to and away from each other to adjust the size of the clamping opening 3101, thereby making the size of the clamping opening 3101 compatible with the size of the sheet 91 so that the sheet 91 can be clamped. It should be noted that in this embodiment, the clamping drive member 312 is implemented as a telescopic cylinder. In addition, compared with the previous variant embodiment, the time used to clamp the sheet 91 in this embodiment is shorter, which is conducive to improving the overall efficiency of riveting the sheet 91.

[0048] To facilitate understanding of the present invention by those skilled in the art, the present invention will be described below using at least one embodiment in which the two clamping arms 311 are connected to the output ends of the clamping drive member 312 in a relative and spaced manner to form a clamping opening 3101. The clamping drive member 312 is provided in the material moving assembly 32, and is configured to drive the two clamping arms 311 to move relative to each other to adjust the size of the clamping opening 3101. That is, the sheet material 91 placed in the placement slot 2101 can be clamped when the clamping drive member 312 drives the two clamping arms 311 to move relative to each other.

[0049] Specifically, in one example, the material moving assembly 32 includes a pushing member 321, a vertical drive unit 322, and a transverse drive unit 323, wherein the pushing member 321 is mounted at the output end of the vertical drive unit 322, and the clamping drive member 312 is movably connected to the pushing member 321. The vertical drive unit 322 is mounted at the output end of the transverse drive unit 323, and the vertical drive unit 322 is configured to drive the pushing member 321 in the vertical direction so that the sheet 91 is opposite to the clamp 3101. The transverse drive unit 323 is provided in the device body 10, and the transverse drive unit 323 is configured to drive the vertical drive unit 322 toward the riveting assembly 40 in the horizontal direction.

[0050] It can be understood that the vertical movement drive unit 322 is started to make the clamping assembly 31 as a whole be located at a predetermined position where the sheet material 91 can maintain a relative position with the clamping opening 3101. At this time, the pushing member 321 is started to make the clamping assembly 31 as a whole close to the sheet material 91 located in the placement groove 2101 until the part of the sheet material 91 located in the notch 2103 is located in the clamping opening 3101. Thus, the size of the clamping opening 3101 is adjusted by driving the clamping arm 311 through the clamping drive member 312, so that the sheet material 91 can be clamped.

[0051] It is worth mentioning that when the clamping assembly 31 has clamped the sheet material 91 placed in the placement groove 2101, the vertical drive unit 322 is started to drive the clamping assembly 31 and the clamped sheet material 91 to gradually move above the loading platform 21, so that the sheet material 91 is completely separated from the placement groove 2101, and then the transverse drive unit 323 is started to drive the clamping assembly 31 as a whole, the vertical drive unit 322 and the clamped sheet material 91 to move toward the riveting assembly 40 until the sheet material 91 clamped by the clamping assembly 31 is located in the area to be riveted.

[0052] Preferably, in this example, the pushing member 321 , the vertical drive unit 322 and the horizontal drive unit 323 are all implemented including but not limited to hydraulic cylinders and telescopic cylinders.

[0053] Specifically in another example, Figure 4 and Figure 5As shown, the material moving assembly 32 includes a pushing member 321, a vertical drive unit 322 and a transverse drive unit 323, wherein the pushing member 321 includes at least one limiting guide rail 3211 and a pushing drive member 3212. The limiting guide rail 3211 is fixedly connected to the support frame 22 of the detection assembly 20, and the loading platform 21 is movably connected to the limiting guide rail 3211, and the extension direction of the limiting guide rail 3211 is consistent with the moving direction of the loading platform 21. The pushing drive member 3212 is installed on the support frame 22, and the loading platform 21 is movably connected to the output end of the pushing drive member 3212. The vertical drive unit 322 can be driven and driven to be connected to the clamping drive member 312, and the vertical drive unit 322 is installed on the transverse drive unit 323. The transverse driving unit 323 is disposed on the device body 10 , and the transverse driving unit 323 is configured to drive the vertical driving unit 322 toward the riveting assembly 40 along a horizontal direction.

[0054] It can be understood that when the vertical movement drive unit 322 drives the clamping assembly 31 as a whole to be located at a predetermined position where the sheet material 91 can be maintained relative to the clamp 3101, the pushing drive member 3212 is started to drive the loading platform 21 to move along the extension direction of the limiting guide rail 3211, so that the sheet material 91 placed on the placement groove 2101 also gradually extends into the clamp 3101 along the extension direction of the limiting guide rail 3211. At this time, the clamping assembly 31 can clamp the sheet material 91 by adjusting the clamp 3101, and then continue to start the vertical movement drive unit 322 to make the clamping assembly 31 as a whole and the clamped sheet material 91 be taken away from the loading platform 21, thereby, the material moving assembly 32 can drive the clamping assembly 31 as a whole and the clamped sheet material 91 to move toward the riveting assembly 40, so that the sheet material 91 can be riveted.

[0055] As an example, the transverse drive unit 323 includes a transverse drive member 3231 and a transmission member 3232, wherein the transverse drive member 3231 can be driven and driven to connect the transmission member 3232. The transmission member 3232 is connected to the device body 10, and the transmission member 3232 is arranged to extend toward the riveting assembly 40 to form a track, and the vertical drive unit 322 is driven and movably connected to the transmission member 3232, and then when the transverse drive member 3231 drives the transmission member 3232 to move the vertical drive unit 322, the clamping assembly 31 as a whole and the clamped sheet material 91 can be driven along the moving direction of the vertical drive unit 322 on the track. It should be noted that the transverse drive member 3231 is implemented as a motor. The transmission member 3232 is implemented to include a ball screw transmission device.

[0056] It is worth mentioning that the vertical movement drive unit 322 can also be configured to be composed of a motor and a ball screw transmission device.

[0057] Specifically in one example, Figures 6 to 10 As shown, the riveting assembly 40 includes a mounting frame 41, a riveting driver 42, a riveting unit 43 and a riveting platform 44, wherein the mounting frame 41 is connected to the device body 10, and the riveting driver 42 is connected to the mounting frame 41. The riveting unit 43 is movably connected to the riveting driver 42, and the end of the riveting unit 43 away from the riveting driver 42 forms a pressing portion 431, and the riveting driver 42 is configured to drive the riveting unit 43 so that the pressing portion 431 is pressed toward the riveting platform 44. In addition, the riveting unit 43 is also evenly provided with a plurality of magnetic elements 432 on the pressing portion 431 so that a nut member 92 is adsorbed on the pressing portion 431. The riveting platform 44 has a riveting portion 441 spaced a predetermined distance from the pressing portion 431, and the riveting portion 441 has an arc-shaped riveting surface with an arc surface convex toward the pressing portion 431.

[0058] It can be understood that when the riveting drive member 42 is started so that the pressing portion 431 of the riveting unit 43 presses the nut member 92 toward the riveting portion 441 of the riveting table 44, one end of the nut member 92 gradually passes through the riveting hole of the sheet material 91 conveyed by the blanking device 30. At the same time, the riveting portion 441 abuts against the inner wall of the nut member 92, so that the end of the nut member 92 passing through the sheet material 91 gradually tends to be flattened and fixed on the sheet material 91. Thus, the sheet material 91 completes the riveting operation of a riveting hole.

[0059] It is worth mentioning that each of the sheet materials 91 sent to the riveting assembly 40 by the blanking device 30 needs to complete the riveting operation on both riveting holes. Therefore, the material moving assembly 32 of the blanking device 30 can drive the clamping assembly 31 to move as a whole, so that the sheet material 91 clamped by the clamping assembly 31 follows the overall movement of the clamping assembly 31, that is, the two riveting holes of each sheet material 91 are successively moved and located on the path of the riveting unit 43 to press the nut part 92, so that the two riveting holes of each sheet material 91 can be pressed with the nut part 92.

[0060] Specifically, in another example, the riveting assembly 40 includes a mounting frame 41, a riveting driver 42, a riveting unit 43 and a riveting table 44, wherein the mounting frame 41 is movably connected to the device body 10, and the riveting driver 42 is connected to the mounting frame 41. The riveting unit 43 is movably connected to the riveting driver 42, and the end of the riveting unit 43 away from the riveting driver 42 forms a pressing portion 431, and the riveting driver 42 is configured to drive the riveting unit 43 so that the pressing portion 431 is pressed toward the riveting table 44. In addition, the riveting unit 43 is also evenly provided with a plurality of magnetic elements 432 on the pressing portion 431 so that a nut member 92 is adsorbed on the pressing portion 431. The riveting platform 44 has two riveting parts 441 spaced a predetermined distance from the pressing part 431 . The two riveting parts 441 are disposed opposite to each other and spaced a predetermined distance apart. Each riveting part 441 has an arc-shaped riveting surface that convexly faces the pressing part 431 .

[0061] It can be understood that when the unloading device 30 transports the sheet material 91 to between the pressing part 431 and the riveting part 441, the riveting driving part 42 is started so that the pressing part 431 of the riveting unit 43 first presses a nut part 92 through a riveting hole of the sheet material 91 to complete the riveting operation of one riveting hole of the sheet material 91, and then the mounting frame 41 is moved so that the riveting driving part 42 and the riveting unit 43 follow the movement, so that the pressing part 431 gradually aligns with the other riveting hole of the sheet material 91 after movement, and re-adsorbs a new nut part 92 on the pressing part 431 through the magnetic element 432, so that the other riveting hole of the sheet material 91 can complete the riveting operation.

[0062] In order to enable those skilled in the art to understand the present invention, the present invention only includes the riveting assembly 40 including a mounting frame 41, a riveting driving member 42, a riveting unit 43 and a riveting table 44, wherein the mounting frame 41 is connected to the device body 10, and the riveting driving member 42 is connected to the mounting frame 41, the riveting unit 43 is movably connected to the riveting driving member 42, and the end of the riveting unit 43 away from the riveting driving member 42 forms a pressing portion 431, and the riveting driving member 42 is configured to drive the riveting unit 43 to The pressing portion 431 is pressed toward the riveting table 44. The riveting unit 43 also evenly arranges multiple magnetic elements 432 on the pressing portion 431 to allow a nut part 92 to be adsorbed on the pressing portion 431. The riveting table 44 has a riveting portion 441 that is spaced a predetermined distance from the pressing portion 431. The riveting portion 441 has an arc-shaped riveting surface that convexly faces the pressing portion 431. That is, the clamped sheet material 91 is moved by the blanking device 30 so that both riveting holes of the sheet material 91 can be riveted to the nut part 92 by the riveting assembly 40.

[0063] In this way, when the automatic nut riveting equipment rivets the nut part 92 onto each of the sheet materials 91, the unloading device 30 can replace manual labor to complete the purpose of moving the sheet materials 91, so that both riveting holes of the sheet materials 91 can be pressed with the nut parts 92, thereby reducing the risk of manual operation while also improving the riveting efficiency of each of the sheet materials 91.

[0064] Preferably, the riveting unit 43 is further provided with a limiting portion 433 at the position of the pressing portion 431, and the limiting portion 433 extends axially outward as a whole by a predetermined length, and the limiting portion 433 has an arc-shaped guide surface that is convex in the same direction as the extension direction, and then when the nut member 92 is adsorbed on the pressing portion 431 by the magnetic element 432, the limiting portion 433 is arranged to at least partially penetrate the inner hole of the nut member 92, due to the limiting effect of the limiting portion 433, the posture of the nut member 92 adsorbed on the pressing portion 431 is determined, so that the nut member 92 can be accurately pressed toward and penetrated into the sheet material 91 by the riveting unit 43 to complete the riveting operation.

[0065] In a modified embodiment, the riveting table 44 is movably connected to the mounting frame 41, and the riveting table 44 is arranged to approach the riveting unit 43 in a direction parallel to the moving direction of the riveting unit 43, so that when the automatic nut riveting equipment performs a riveting operation on one of the sheet materials 91, the nut piece 92 pressed by the riveting unit 43 can contact the riveting part 441 more quickly, thereby shortening the time of a single riveting to improve the riveting efficiency.

[0066] Preferably, the riveting driving member 42 is implemented as, but not limited to, a telescopic cylinder. The magnetic attraction element 432 is implemented as a magnet.

[0067] Furthermore, the riveting assembly 40 further includes a spring member 45 , wherein the riveting platform 44 forms a groove 4401 penetrating the riveting portion 441 to accommodate the spring member 45 .

[0068] Preferably, the elastic pressing member 45 includes a push rod 451 and an elastic element 452, wherein the push rod 451 is movably disposed in the channel 4401 and connected to one end of the elastic element 452. The other end of the elastic element 452 away from the push rod 451 is connected to the bottom wall forming the channel 4401, and the elastic element 452 is configured to press one end of the push rod 451 so that the push rod 451 is at least partially located outside the channel 4401. When the pressing portion 431 is pressed toward the riveting platform 44, the push rod 451 is abutted by the limiting portion 433 and gradually accommodated in the channel 4401, pressing the elastic element 452.

[0069] It can be understood that when the riveting unit 43 is driven by the riveting driving member 42 and the pressing portion 431 presses the nut member 92 toward the riveting portion 441 of the riveting table 44, the end of the nut member 92 abutted by the riveting portion 441 is gradually flattened, so that the limiting portion 433 inserted into the nut member 92 gradually abuts against the push rod 451, and then the push rod 451 is acted upon to squeeze the elastic element 452, so that the elastic element 452 is deformed along the axial direction. At this time, the push rod 451 is gradually accommodated in the groove 4401, thereby avoiding the limiting portion 433 directly abutting against the riveting portion 441, so that the part of the nut member 92 passing through the sheet 91 cannot be completely flattened, resulting in the nut member 92 being difficult to be firmly connected to the sheet 91.

[0070] Preferably, the elastic element 452 is implemented as a control spring.

[0071] Preferably, the riveting assembly 40 also includes a detector 46. Preferably, the detector 46 is movably connected to the mounting bracket 41, and the moving direction of the detector 46 is parallel to the moving direction of the riveting unit 43. The detector 46 is configured to detect the distance that the riveting driving member 42 drives the riveting unit 43 to move, so that the distance that the riveting unit 43 presses the nut member 92 toward the riveted portion 441 is controlled to prevent one end of the nut member 92 from being excessively flattened.

[0072] Furthermore, the automatic nut riveting equipment also includes a nut processing device 50, which is used to replace manual labor to provide the nut part 92 to the riveting assembly 40, and can automatically supply the nut part 92 to the riveting unit 43, so that the pressing part 431 of the riveting unit 43 can press the nut part 92 toward the riveting hole of the sheet material 91.

[0073] Specifically, if Figure 1 and Figure 3 As shown, the nut processing device 50 includes a nut supply component 51 and a nut releasing component 52, wherein the nut supply component 51 has a nut supply space 5101 for storing the provided nut member 92, and the nut supply component 51 is arranged to extend toward the nut releasing component 52 to form a transmission pipe 511 to transmit the nut member 92 to the nut releasing component 52.

[0074] The transmission pipe 511 defines a high end and a low end, wherein the high end is connected to the nut supply space 5101, and the low end corresponds to the nut release member 52. Thus, the nut member 92 transmitted through the nut supply space 5101 moves from the position of the high end to the position of the low end under the action of gravity to enter the nut release member 52.

[0075] The nut releasing member 52 includes a releasing body 521, a pair of releasing arms 522, and the same number of elastic members 523 as the releasing arms 522. The releasing body 521 is connected to the device body 10 and has a releasing channel 52101. The releasing channel 52101 is connected to the lower end of the transmission pipe 511. The two releasing arms 522 are rotatably connected to the releasing body 521 and are arranged opposite to each other and spaced apart to form a groove 52201. The groove 52201 is maintained on the moving path of the pressing portion 431 of the riveting unit 43, and the groove 52201 is arranged to extend toward the outlet of the releasing channel 52101 to communicate with the releasing channel 52101. One end of each elastic member 523 is arranged to abut against one of the release arms 522 , and the other end of each elastic member 523 is arranged to abut against the release body 521 , so that when the release arm 522 rotates, the elastic member 523 is arranged to generate elastic force along the axial direction.

[0076] It can be understood that the nut member 92 transmitted through the nut feeding member 51 can enter the release channel 52101 of the release body 521 under the action of gravity after entering the transmission pipe 511, and finally move to the release arm 522 to form the groove 52201. Then, when the riveting unit 43 is driven to move, the pressing part 431 of the riveting unit 43 presses the nut member 92 located in the groove 52201 toward the sheet material 91, and the two release arms 522 are pushed by the pressing part 431 and rotated by a predetermined angle along the axial direction of the elastic member 523 abutting against themselves. At this time, each elastic member 523 generates elastic force in the axial direction, so that when the riveting unit 43 no longer pushes the release arm 522, each release arm 522 can be driven by the elastic force to return to its original position and form the groove 52201 again to collect the nut member 92.

[0077] It is worth mentioning that when the riveting unit 43 presses one of the nut members 92 toward the sheet material 91, the riveting unit 43 is partially located at the exit of the release channel 52101, thereby blocking the movement path of the other nut members 92 located in the release channel 52101. In other words, when one of the nut members 92 is being riveted, the other nut members 92 located in the release channel 52101 cannot move to the position where the groove 52201 is formed.

[0078] Furthermore, the nut processing device 50 also includes a nut operating member 53, wherein the release body 521 also has a pushing channel 52102 connected to the release channel 52101, and the pushing channel 52102 is arranged to be connected to the groove 52201 for the nut operating member 53 to push the nut part 92 into the groove 52201.

[0079] Preferably, the nut operating member 53 includes a push rod 531 and an auxiliary driving member 532, wherein the push rod 531 is movably disposed in the pushing channel 52102. The auxiliary driving member 532 is connected to the release body 521 and can be driven and movably connected to the push rod 531 to drive the push rod 531 to move toward the groove 52201. When the nut member 92 enters the pushing channel 52102 from the release channel 52101, the auxiliary driving member 532 is activated to cause the push rod 531 to gradually abut against one of the nut members 92 and tend to push the nut member 92 toward the groove 52201.

[0080] Preferably, the nut supply member 51 is implemented as a vibration plate. Each of the elastic members 523 is implemented as a torsion spring. The booster drive member 532 is implemented including but not limited to a hydraulic cylinder or a telescopic cylinder.

[0081] Furthermore, the automatic nut riveting equipment also includes a loading device 60, which can replace manual placement of the sheet material 91 on the loading platform 21 to automatically place the sheet material 91 into the placement slot 2101 of the loading platform 21.

[0082] Specifically, the loading device 60 includes a feeding component 61, at least one suction component 62 and a transfer drive component 63, wherein the feeding component 61 includes a feeding body 611 and a plurality of fixing components 612, the feeding body 611 is connected to the equipment body 10, and the fixing components 612 are evenly connected to the feeding body 611 to form at least one feeding space 6101, and the size of the feeding space 6101 is set to be adapted to the size of each of the sheets 91, so that the sheets 91 can be placed in the feeding space 6101 in a neatly stacked manner, as shown. Figure 1 and Figure 3 shown.

[0083] The suction member 62 is movably disposed on the transfer driving member 63 and maintained above the feeding body 611 , and the suction member 62 is configured to form negative pressure when contacting the surface of the sheet material 91 to absorb the sheet material 91 .

[0084] The transfer drive member 63 includes a first drive member 631 and a second drive member 632, wherein the first drive member 631 is movably connected to each of the suction members 62, and the first drive member 631 is movably connected to the second drive member 632. The second drive member 632 is connected to the device body 10, and when the suction member 62 absorbs the sheet material 91, the second drive member 632 is configured to drive the first drive member 631 to move a predetermined distance in the horizontal direction so that the sheet material 91 corresponds to the placement slot 2101 of the loading platform 21.

[0085] It can be understood that when the second driving member 632 is started to drive the first driving member 631 to move above the feeding body 611, the first driving member 631 is started to drive the suction member 62 to extend into the feeding space 6101, so that one of the sheet materials 91 contacts the suction member 62 and is adsorbed on the suction member 62. At this time, the first driving member 631 drives the suction member 62 to disengage from the feeding space 6101, so that the second driving member 632 drives the first driving member 631 horizontally to move above the loading platform 21. At this time, the suction member 62 and the sheet material 91 adsorbed by the suction member 62 follow the movement of the first driving member 631, and the sheet material 91 gradually corresponds to the placement groove 2101 in the process of approaching the loading platform 21. At this time, the first driving member 631 can be driven to drive the adsorbed sheet material 91 to extend into the placement groove 2101.

[0086] It is worth mentioning that the placement posture of the sheet material 91 placed in the feeding space 6101 remains the same as the placement posture of the sheet material 91 in the placement groove 2101, so that the sheet material 91 adsorbed by the suction part 62 from the feeding space 6101 can be moved a predetermined distance along a preset direction and then directly placed in the placement groove 2101.

[0087] In a specific example, Figure 4 As shown, the number of the suction members 62 is set to four, and the suction members 62 are evenly and spaced apart on the first driving member 631, so that when the suction members 62 are driven to contact the surface of one of the sheet materials 91, each of the suction members 62 is configured to form a negative pressure to adsorb at least a partial area of ​​the surface of the sheet material 91, so that the sheet material 91 is stably adsorbed.

[0088] It is worth mentioning that each of the suction members 62 is implemented as a suction cup.

[0089] In a modified embodiment, the suction member 62 is configured to be connected to a negative pressure generating device to form negative pressure, thereby enhancing the adsorption effect on the sheet material 91 while also facilitating the automatic separation of the sheet material 91 from each suction member 62.

[0090] In a preferred embodiment, the first driving member 631 is configured as a telescopic cylinder, and the second driving member 632 is configured as an electric cylinder, wherein the telescopic cylinder is movably connected to the electric cylinder, and the telescopic cylinder has a telescopic end, and the suction member 62 is connected to the telescopic end of the telescopic cylinder, and then when the suction member 62 adsorbs the sheet material 91 located in the feeding space 6101, the telescopic cylinder is started so that the telescopic cylinder drives the suction member 62 close to the sheet material 91, so that the sheet material 91 can be adsorbed by the suction member 62, and after the suction member 62 adsorbs the sheet material 91, the electric cylinder is started so that the telescopic cylinder is driven in a straight line toward the loading platform 21, so that the sheet material 91 can be placed in the placement groove 2101.

[0091] In a modified embodiment, the feeding body 611 of the feeding component 61 is configured to be movable toward the suction member 62 in a vertical direction so that the sheet material 91 located in the feeding space 6101 is close to the suction member 62, so that the suction member 62 can adsorb the sheet material 91. In this way, the time for adsorbing the sheet material 91 is shortened, which is beneficial to improving the overall riveting efficiency.

[0092] Furthermore, the automatic nut riveting equipment also includes a recovery unit 70 for collecting the sheet material 91 placed in the placement groove 2101 with the front side facing up.

[0093] Preferably, the recovery unit 70 includes a recovery member 71 and a guide frame 72, wherein the recovery member 71 is connected to the device body 10 and has a receiving cavity 7101. The guide frame 72 is disposed above the recovery member 71 and extends toward the recovery member 71, and is configured to form an annular guide channel 7201. The upper end of the guide channel 7201 is configured to allow the sheet material 91 to enter, and the lower end of the guide channel 7201 is connected to the receiving cavity 7101.

[0094] It is understandable that if Figure 1 As shown, the unloading device 30 can take out the sheet material 91 placed with the front side facing up from the placement groove 2101, and carry the sheet material 91 to the high end of the guide channel 7201 formed by the guide frame 72, so that the sheet material 91 entering from the high end of the guide channel 7201 can enter the storage cavity 7101 of the recovery part 71 from the guide channel 7201 from top to bottom under the action of gravity.

[0095] Furthermore, the automatic nut riveting equipment further includes a finished product conveying unit 80, which is used to convey the sheet material 91 that has completed the riveting operation. Preferably, the finished product conveying unit 80 includes a conveying member 81 and a slide 82, wherein the conveying member 81 is connected to the equipment body 10, and the conveying member 81 is arranged in the direction of the slide 82 to form a conveying channel 8101 to convey the sheet material 91. The slide 82 is connected to the outlet of the conveying channel 8101, and the slide 82 forms an inclined slide 821, the high end of the inclined slide 821 is arranged to receive the outlet of the conveying channel 8101, and the extension direction of the low end of the inclined slide 821 is arranged to be consistent with the direction in which the conveying member 81 conveys the sheet material 91.

[0096] It is understandable that if Figure 1 and Figure 3 As shown, after the sheet material 91 completes the riveting operation, the unloading device 30 can transport the sheet material 91 to the conveying channel 8101 of the conveying component 81, so that the conveying component 81 conveys the sheet material 91 to the slide 82, thereby, the sheet material 91 that completes the riveting operation can be collected at the outlet of the inclined slide 821.

[0097] Preferably, the conveying member 81 is implemented as a conveyor belt transmission device.
