[0046] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0047] See also Figures 1 to 12 , the present embodiment provides a rivet nut press-fitting device, which includes a first loader 210 and a first transfer device 220, wherein the first loader 210 is configured to supply the rivet nut 110 to the first loading station. For example, in the present embodiment, the first loader 210 is a vibration plate, and the vibration plate can supply the rivet nut 110 to the first loading station. Of course, in other optional embodiments, the first loader 210 can also be other nut loaders, and this embodiment does not impose specific restrictions on this. In addition, it can be understood that since the specific structure and working principle of the vibration plate are both prior art, this embodiment will not be described in detail. The first transfer device 220 includes a first handling mechanism 221, and the first handling mechanism 221 is configured to transport the rivet nut 110 located at the first loading station to the assembly station.

[0048] In addition to the first feeder 210 and the first transfer device 220, the rivet nut press-fitting equipment further includes a second feeder 230, a second transfer device 240, a third transfer device 250 and a press-fitting device 260, wherein the second feeder 230 is configured to supply the fixing sheet 120 to the second feeding station, and the second transfer device 240 includes a second handling mechanism 241, and the second handling mechanism 241 is configured to transport and place the fixing sheet 120 located at the second feeding station to the combination The third transfer device 250 is configured to transfer the fixed sheet 120 combined with the rivet nut 110 to the press-fitting station, and the press-fitting device 260 is arranged at the press-fitting station, and the press-fitting device 260 includes a pressing head 261, which can be lifted and lowered in the vertical direction. A guide pin 2611 is provided at the bottom of 261, and the guide pin 2611 can be inserted into the rivet nut 110, and the pressure head 261 can press the rivet nut 110 along the axial direction of the rivet nut 110. In other words, the pressure head 261 can press the rivet nut 110 in the vertical direction to deform the rivet nut 110 and form a deformed portion along its radial direction, so that the fixing sheet 120 is squeezed and limited between the deformed portion and the head of the rivet nut 110. It can be understood that when the pressure head 261 In the process of pressing down to deform the rivet nut, since the guide pin 2611 is inserted into the rivet nut 110 and gradually penetrates into the rivet nut 110 as the pressure head 261 is pressed down, the guide pin 2611 can provide a guide for the pressure head 261 to press down the rivet nut 110. On the other hand, the guide pin 2611 can also play a limiting role, thereby ensuring that the rivet nut 110 is accurately deformed radially outward, that is, the guide pin 2611 can prevent the rivet nut 110 from being skewed.

[0049] Based on the above, in this embodiment, the rivet nut 110 and the fixing plate 120 are respectively supplied by the first feeder 210 and the second feeder 230, and the rivet nut 110 and the fixing plate 120 are respectively transferred by the first transfer device 220 and the second transfer device 240, so that the rivet nut 110 and the fixing plate 120 are combined together. In addition, in this embodiment, the combined fixing plate 120 and the rivet nut 110 are transferred to the press-fitting device 260 by the third transfer device 250, and the press-fitting device 260 can automatically press the rivet nut 110 onto the fixing plate 120. Compared with manually tightening the rivet nut 110, the working efficiency of the rivet nut press-fitting equipment is higher, thereby improving production efficiency.

[0050] Specifically, the first transfer device 220 first transfers the rivet nut 110 to the assembly station, and then the second transfer device 240 transfers the fixing plate 120 to the assembly station and passes the rivet nut 110 through the mounting hole 121 on the fixing plate 120 so that the fixing plate 120 is sleeved on the outer periphery of the rivet nut 110.

[0051] It is worth noting that, illustratively, in this embodiment, the second loader 230 is a push plate type lifting loader, and the downstream end of the second loader 230 is connected to the first conveyor line 270, and the second loader 230 can convey the fixed sheet 120 to the first conveyor line 270, and the first conveyor line 270 can transfer the fixed sheet 120 to the second loading station. Of course, in other optional embodiments, the second loader 230 can also be other material loader, and this embodiment does not specifically limit this. In addition, it can be understood that since the specific structure and working principle of the push plate type lifting loader are both existing technologies, this embodiment will not be described in detail.

[0052] In addition, the downstream end of the first loader 210 is connected to the second conveyor line 280. The first loader 210 can convey the rivet nuts 110 to the second conveyor line 280, and the second conveyor line 280 can transfer the rivet nuts 110 to the first loading station.

[0053] It can be understood that in this embodiment, the first conveyor line 270 and the second conveyor line 280 are both direct vibration conveyor lines. Of course, in other optional embodiments, the first conveyor line 270 and the second conveyor line 280 can also be selected as other conveyor line structures such as belt conveyor lines, and this embodiment does not make specific restrictions on this.

[0054] In this embodiment, the first handling mechanism 221 includes a first clamping jaw 2211, a first driving member 2212 and a second driving member 2213, wherein the first driving member 2212 is used to drive the first clamping jaw 2211 to rise and fall in the vertical direction, so that the first clamping jaw 2211 can clamp the rivet nut 110 from the first loading station or place the rivet nut 110 to the assembly station, and the second driving member 2213 is used to drive the first clamping jaw 2211 to move in the horizontal direction, so that the first clamping jaw 2211 moves between the first loading station and the assembly station. Specifically, the first clamp 2211 can firstly descend in the vertical direction at the first loading station, so as to clamp the rivet nut 110 at the first loading station, and then the first clamp 2211 is lifted and then moved in the horizontal direction to the assembly station. The first clamp 2211 moved to the assembly station descends in the vertical direction, so as to place the rivet nut 110 at the assembly station, and then the first clamp 2211 is lifted and then returned to the first loading station to clamp and transfer the next rivet nut 110.

[0055] It is understandable that in this embodiment, the first clamping jaw 2211 may be a pneumatic clamping finger, a pneumatic chuck or other clamping jaw structure, which is not specifically limited in this embodiment. The first driving member 2212 and the second driving member 2213 may be a linear driving structure such as a cylinder, an electric cylinder or a KK module, which is not specifically limited in this embodiment.

[0056] In addition, it is also worth mentioning that in the present embodiment, two mounting holes 121 are provided on the fixing plate 120. Accordingly, the second conveyor line 280 includes two conveying channels 281. The first loader 210 is a vibration plate having two feeding channels. The two feeding channels of the vibration plate are respectively connected to the two conveying channels 281 of the second conveyor line 280. Of course, in other optional embodiments, the first loader 210 may also be selected to be composed of two vibration plates, and the two vibration plates can feed materials to the two conveying channels 281 respectively, thereby simultaneously supplying the rivet nuts 110 to the first loading station. There is no specific limitation on this in the present embodiment.

[0057] Based on the above, in the present embodiment, the first handling mechanism 221 includes two first clamps 2211, and the two first clamps 2211 are both installed on the first mounting plate 223. The first driving member 2212 can drive the first mounting plate 223 to rise and fall in the vertical direction, and the second driving member 2213 can drive the first mounting plate 223 to move in the horizontal direction, thereby driving the two first clamps 2211 to move in the vertical direction or in the horizontal direction at the same time, thereby simultaneously delivering two rivet nuts 110 to the assembly station at one time.

[0058] It can be understood that the relative positions of the two first clamps 2211 can be designed according to the relative positions of the two mounting holes 121 on the fixing plate 120. Correspondingly, the relative positions of the downstream ends of the two conveying channels 281 are also designed according to the relative positions of the two mounting holes 121 on the fixing plate 120, thereby ensuring that the two rivet nuts 110 placed at the assembly station can pass through the two mounting holes 121 on the fixing plate 120 respectively.

[0059] Of course, in other optional embodiments, the fixing plate 120 may also have one or three or other numbers of mounting holes 121. Accordingly, the first handling mechanism 221 includes a corresponding number of first clamps 2211 and first driving members 2212, the second conveyor line 280 includes a corresponding number of conveying channels 281, and the first loader 210 is a vibration plate with a corresponding number of feeding channels, or the first loader 210 includes a corresponding number of vibration plates.

[0060] Based on the above, in this embodiment, the second handling mechanism 241 includes a clamping module and a third driving member 2413. The clamping module can clamp the fixing plate 120, and the third driving member 2413 can drive the clamping module to move in the horizontal direction, so as to transport the fixing plate 120 from the second loading station to the assembly station.

[0061] It is understandable that the third driving member 2413 may be a linear driving structure such as a cylinder, an electric cylinder or a KK module, and this is not specifically limited in the present embodiment.

[0062] Furthermore, in addition to the first handling mechanism 221, the second transfer device 240 also includes a first carrier 242, which is located at the second loading station and is provided with a receiving groove 2421. The second loader 230 can move the fixing plate 120 placed in a preset direction into the receiving groove 2421, thereby positioning the fixing plate 120.

[0063] In addition, based on the content mentioned above, in this embodiment, the fixing plate 120 is placed in a preset direction along its length direction. It is worth noting that in this embodiment, the two mounting holes 121 on the fixing plate 120 are not symmetrically arranged relative to the center position of the fixing plate 120. Therefore, for the fixing plate 120 arranged along its length direction, when the fixing plate 120 is moved into the receiving groove 2421, there are two placement situations of the fixing plate 120. The first placement situation is that the fixing plate 120 is placed upright along its length direction, and the second placement situation is that the fixing plate 120 is placed inverted along its length direction. In both cases, the positions of the two mounting holes 121 relative to the receiving groove 2421 are different. In order to ensure that the subsequent rivet nut 110 can pass through the mounting hole 121 on the fixing plate 120, it is necessary to make all the fixing plates 120 sent to the assembly station by the second conveying mechanism always in the first placement situation or the second placement situation, that is, the placement situation of all the fixing plates 120 sent to the assembly station by the second conveying mechanism needs to be the same.

[0064] To this end, the second transfer device 240 also includes a second carrier 243, and a positioning groove 2431 is provided on the second carrier 243. The second handling mechanism 241 can transport the fixing plate 120 from the receiving groove 2421 to the positioning groove 2431. It can be understood that in this embodiment, the positioning groove 2431 and the receiving groove 2421 are arranged in a straight line direction. Specifically, the positioning groove 2431 and the receiving groove 2421 are arranged in parallel, and the second carrier 243 can rotate around a vertical axis, and the vertical axis passes through the center of the positioning groove 2431. On the one hand, the positioning groove 2431 can move the fixing plate 120 Secondary positioning, on the other hand, the second carrier 243 can adjust the posture of the fixing plate 120 by rotating 180°. For example, if all the fixing plates 120 sent to the assembly station by the second transport mechanism need to always be in the first arrangement state, the second carrier 243 can adjust the fixing plates 120 in the second arrangement state to the first arrangement state by rotating 180°, thereby ensuring that the positions of the two mounting holes 121 on the fixing plates 120 transferred to the assembly station meet the preset requirements, thereby ensuring that the subsequent rivet nuts 110 can accurately pass through the mounting holes 121 on the fixing plates 120.

[0065] In addition, it should be noted that if only one mounting hole 121 is provided on the fixed plate 120, and the mounting hole 121 is not arranged at the center position of the fixed plate 120, the second carrier 243 can adjust the position of the fixed plate 120 by rotation. If the fixed plate 120 is provided with several mounting holes 121, and there are two mounting holes 121 on the fixed plate 120 that are not symmetrically arranged relative to its center position, the second carrier 243 can also adjust the position of the fixed plate 120 by rotation.

[0066] It is understandable that if the mounting hole 121 is disposed at the center of the fixing plate 120, or all mounting holes 121 on the fixing plate 120 are symmetrically disposed relative to the center of the fixing plate 120, the second carrier 243 does not need to be rotated and is only used for secondary positioning.

[0067] Furthermore, a first detector (not shown in the figure) is installed on the first carrier 242, and the first detector is configured to detect the position of the fixing plate 120 accommodated in the accommodating groove 2421. Subsequently, the second carrier 243 can decide whether to rotate 180° based on the detection result of the first detector.

[0068] Exemplarily, the two mounting holes 121 are respectively the first mounting hole and the second mounting hole. In this embodiment, the first detector is a first photoelectric sensor, and the first detector is buried in the first carrier 242. When the fixing plate 120 accommodated in the accommodating groove 2421 is in the first placement state, the first mounting hole is located above the first detector. At this time, the first detector can detect that the fixing plate 120 is in the first placement state, and the subsequent second carrier 243 does not need to be rotated 180°. Correspondingly, if the fixing plate 120 accommodated in the accommodating groove 2421 is in the second placement state, the first mounting hole is not located above the first detector, and the second mounting hole is not located above the first detector. At this time, the first detector can detect that the fixing plate 120 is in the second placement state, and the subsequent second carrier 243 needs to be rotated 180° to adjust the posture of the fixing plate 120.

[0069] Of course, in other optional embodiments, the first detector may also be a camera or other visual detection structure, which is not specifically limited in this embodiment.

[0070] Furthermore, a second detector is installed on the second carrier 243, and the second detector is configured to detect the position of the fixing plate 120 accommodated in the positioning groove 2431, so as to further ensure that the positions of the two mounting holes 121 on the fixing plate 120 accommodated in the positioning groove 2431 meet the preset requirements.

[0071] Specifically, the two mounting holes 121 are respectively the first mounting hole and the second mounting hole. In this embodiment, the second detector includes two second photoelectric sensors, and the second detector is buried in the second carrier 243. When the fixing plate 120 accommodated in the positioning groove 2431 is in the first placement state, the first mounting hole and the second mounting hole are respectively located above the two second photoelectric sensors. Correspondingly, if the fixing plate 120 accommodated in the accommodating groove 2421 is in the second placement state, the first mounting hole and the second mounting hole are not located above the two second photoelectric sensors. In this embodiment, the fixing plate 120 can be accurately adjusted to the first placement state by the second detector including the second carrier 243.

[0072] Of course, in other optional embodiments, the second detector may also be a camera or other visual detection structure, which is not specifically limited in this embodiment.

[0073] Based on the contents mentioned above, the clamping module includes a first handling member 2411 and a second handling member 2412, that is, in addition to the third driving member 2413, the second handling mechanism 241 also includes a first handling member 2411 and a second handling member 2412, the first handling member 2411 can transport the fixing plate 120 from the first carrier 242 to the second carrier 243, the second handling member 2412 can transport the fixing plate 120 from the second carrier 243 to the assembly station, and the second handling member 2412 moves synchronously with the first handling member 2411, that is, the second handling member 2412 can transfer the fixing plate 120 on the second carrier 243 to the assembly station while the first handling member 2411 transfers the fixing plate 120 on the first carrier 242 to the second carrier 243, thereby further improving the working efficiency of the rivet nut pressing equipment, and further improving the production efficiency.

[0074] Specifically, the first handling member 2411 and the second handling member 2412 are both installed on the second mounting plate 2414, and the third driving member 2413 can drive the second mounting plate 2414 to move in the horizontal direction, thereby driving the first handling member 2411 and the second handling member 2412 to move synchronously in the horizontal direction. In addition, the second handling mechanism 241 also includes a fourth driving member 2415, and the fourth driving member 2415 is used to drive the second mounting plate 2414 to rise and fall in the vertical direction, thereby driving the first handling member 2411 and the second handling member 2412 to move synchronously in the vertical direction.

[0075] In this embodiment, the first handling member 2411 and the second handling member 2412 are both second clamps, a groove 122 is provided on the fixed plate 120, and the mounting hole 121 is provided on the bottom wall of the groove 122. The second clamp can be selected as a clamp structure such as a pneumatic clamp or a pneumatic chuck. The two claws of the second clamp can be stretched open, so as to be supported between the two side walls of the groove 122 of the fixed plate 120, and thus can clamp the fixed plate 120.

[0076] Of course, in other optional embodiments, the first handling member 2411 and the second handling member 2412 may also be other structures such as suction cups that can handle or release the fixing plate 120, and this is not specifically limited in the present embodiment.

[0077] It is understandable that the fourth driving member 2415 may be selected as a linear driving structure such as a cylinder, an electric cylinder or a KK module, and this is not specifically limited in the present embodiment.

[0078] In addition, based on the content mentioned above, in the present embodiment, the rivet nut 110 is a hexagonal nut, and accordingly, the mounting hole 121 is a hexagonal hole. In order to further ensure that the rivet nut 110 placed at the assembly station can pass through the mounting hole 121 on the fixing plate 120, in the present embodiment, the first transfer device 220 also includes a correction mechanism 222, and the correction mechanism 222 is configured to correct the posture of the rivet nut 110 located at the first loading station, so as to position the rivet nut 110, and further ensure that when the fixing plate 120 is placed later, the rivet nut 110 can accurately pass through the mounting hole 121 on the fixing plate 120.

[0079] Exemplarily, in this embodiment, the correction mechanism 222 includes a third jaw 2221, which can clamp the rivet nut 110 located at the first loading station. Specifically, the two claws of the third jaw 2221 can respectively abut against two oppositely arranged surfaces on the rivet nut 110, thereby correcting the posture of the rivet nut 110.

[0080] Based on the above-mentioned contents, in this embodiment, the correction mechanism 222 includes two third clamping jaws 2221 .

[0081] Further, based on the above, the second loader 230 is a push-plate lifting loader, and the downstream end of the second loader 230 is connected to the first conveyor line 270. In order to enable the second loader 230 to move the fixed plate 120 placed in a preset direction into the receiving groove 2421, in this embodiment, a material removal structure is provided on the first conveyor line 270, and the material removal structure is configured to remove the fixed plate 120 that is not placed in the preset direction from the first conveyor line 270. The downstream end of the first conveyor line 270 is connected to the opening 24211 of the receiving groove 2421, and the fixed plate 120 placed in the preset direction can be moved into the receiving groove 2421 through the opening 24211.

[0082] Specifically, based on the content mentioned above, the first conveyor line 270 includes a first baffle 271 and a second baffle 272, and the first baffle 271 and the second baffle 272 both extend along the conveying direction of the first conveyor line 270. A conveying passage 273 for conveying the fixed plate 120 is formed between the first baffle 271 and the second baffle 272. The width of the conveying passage 273 in a direction perpendicular to the conveying direction of the first conveyor line 270 is slightly larger than the width of the fixed plate 120. A notch 2711 is provided on the first baffle 271. Since the first conveyor line 270 is a straight vibration conveyor line, for the fixed plate 120 not placed in its length direction, when the fixed plate 120 passes through the notch 2711, the fixed plate 120 will fall out of the notch 2711.

[0083] It is understandable that the first conveying line 270 further includes a bottom plate 274 , which is disposed between the first baffle plate 271 and the second baffle plate 272 . The fixing sheet 120 is placed on the bottom plate 274 and can be conveyed forward along the bottom plate 274 . Based on the content mentioned above, a groove 122 is provided on the fixing plate 120. If the fixing plate 120 is reversed on the bottom plate 274, that is, if the groove 122 of the fixing plate 120 is opposite to the bottom plate 274, then even if the fixing plate 120 is placed in the first position, the rivet nut 110 cannot be effectively pressed onto the fixing plate 120. Therefore, the reversed fixing plate 120 also needs to be removed during the transportation process. For this reason, in the present embodiment, the width of the portion of the bottom plate 274 corresponding to the notch 2711 is smaller than the width of the transportation passage 273 and greater than half of the width of the transportation passage 273. For the reversed fixing plate 120, when it passes through the notch 2711, since the side of the fixing plate 120 close to the notch 2711 is not supported by the bottom plate 274, as the first conveyor line 270 shakes, the reversed fixing plate 120 falls out of the notch 2711.

[0084] It can be understood that an arc rod (not shown in the figure) is installed on the second baffle 272. For the stacked fixing plates 120, the arc rod can remove the fixing plate 120 located above. It can be understood that the specific structure and working principle of the arc rod are existing technologies used in vibrating feeders such as vibrating plates. Therefore, this embodiment will not elaborate on this.

[0085] Of course, in other optional embodiments, the material removal structure may also be other structures such as a visual sorting machine, and this is not specifically limited in this embodiment.

[0086] Furthermore, the third transfer device 250 includes a carrier plate 251 and a clamping mechanism 252. The two ends of the carrier plate 251 are respectively provided with an assembly station and a pressing station. The clamping mechanism 252 includes a plurality of clamping blocks 2521. The plurality of clamping blocks 2521 are arranged at intervals along the extension direction of the carrier plate 251. The clamping blocks 2521 can clamp or release the fixing plate 120. The first driving unit 2522 is configured to drive the plurality of clamping blocks 2521 to move back and forth along the extension direction of the carrier plate 251 at the same time, and the moving stroke of the clamping block 2521 is equal to the spacing between two adjacent clamping blocks 2521. The second driving unit 2523 is configured to drive the plurality of clamping blocks 2521 to move simultaneously in a direction perpendicular to the extension direction of the carrier plate 251.

[0087] Specifically, several clamping blocks 2521 are fixedly connected to the third mounting plate 2524, the third mounting plate 2524 is slidably connected to the fourth mounting plate 2525 along the extension direction of the carrier plate 251, the first driving unit 2522 is used to drive the third mounting plate 2524 to reciprocate along the extension direction of the carrier plate 251, the second driving unit 2523 is installed on the fifth mounting plate 2526, the fourth mounting plate 2525 is slidably connected to the fifth mounting plate 2526 along the direction perpendicular to the extension direction of the carrier plate 251, and the second driving unit 2523 is used to drive the fourth mounting plate 2525 to move in the direction perpendicular to the extension direction of the carrier plate 251.

[0088] Among them, the second driving part 2523 can drive several clamping blocks 2521 to approach the fixing plate 120 combined with the rivet nut 110 at the same time, so that several clamping blocks 2521 can clamp a fixing plate 120 combined with the rivet nut 110, and then the first driving part 2522 drives several clamping blocks 2521 to move toward the side close to the pressing station along the extension direction of the carrier plate 251 at the same time, and the moving distance of several clamping blocks 2521 is equal to the spacing between two adjacent clamping blocks 2521, so that several fixing plates 120 combined with the rivet nuts 110 placed on the carrier plate 251 are all toward the fixing plate 120 close to the rivet nut 110. The side close to the pressing station steps once, wherein the fixing plate 120 combined with the rivet nut 110 located on the most downstream side moves to the pressing station, and then the clamping block 2521 releases the fixing plate 120, and the second driving unit 2523 drives several clamping blocks 2521 to move away from the fixing plate 120 combined with the rivet nut 110 at the same time, and then, the first driving unit 2522 drives several clamping blocks 2521 to move simultaneously along the extension direction of the carrier plate 251 toward the side away from the pressing station, and the moving distances of the several clamping blocks 2521 are equal to the spacing between two adjacent clamping blocks 2521, so as to perform the next transfer operation.

[0089] Based on the above, in this embodiment, the fixing plate 120 combined with the rivet nut 110 is moved on the carrier 251 in a stepping manner, so that the fixing plate 120 combined with the rivet nut 110 is stepped from the assembly station to the pressing station for pressing.

[0090] It is understandable that the first driving part 2522 and the second driving part 2523 can both be selected as linear driving structures such as cylinders or electric cylinders, and there is no specific limitation on this in this embodiment.

[0091] Illustratively, in this embodiment, a slot 25211 is provided on the clamp block 2521. When the second driving portion 2523 drives the clamp block 2521 to approach the fixing plate 120 combined with the rivet nut 110, the fixing plate 120 can move into the slot 25211, so that the clamp block 2521 can clamp and drive the fixing plate 120 to move together when moving along the extension direction of the carrier plate 251.

[0092] Of course, in other optional embodiments, the clamping block 2521 may also be a pneumatic clamping finger or a pneumatic chuck, etc., and this is not specifically limited in the present embodiment.

[0093] In addition, two loading grooves 2511 are provided on the carrier plate 251, and the two loading grooves 2511 extend along the extension direction of the carrier plate 251. The first handling mechanism 221 can place the two rivet nuts 110 in the two loading grooves 2511 respectively, and the heads of the rivet nuts 110 are accommodated in the loading grooves 2511 and loaded on the groove walls of the loading grooves 2511. On the one hand, the loading grooves 2511 can ensure that the rivet nuts 110 are stably loaded on the carrier plate 251. On the other hand, the loading grooves 2511 can provide a guide for the movement of the fixing plate 120 combined with the rivet nuts 110.

[0094] Furthermore, a feeding channel 290 is provided at the downstream end of the carrier plate 251 . After the press-fitting device 260 automatically presses the rivet nut 110 onto the fixing plate 120 , the fixing plate 120 can be fed through the feeding channel 290 .

[0095] Furthermore, in this embodiment, the pressing device 260 also includes a mounting seat 262, a pressing block 263 and a spring (not shown in the figure), the pressing head 261 is installed on the mounting seat 262, the pressing block 263 is movably connected to the mounting seat 262 in the vertical direction, the spring extends in the vertical direction and is connected between the top of the pressing block 263 and the mounting seat 262, and the mounting seat 262 can be lowered from the first working position to the second working position in the vertical direction so that the guide pin 2611 is inserted into the rivet nut 110. When the mounting seat 262 is in the first working position, the guide pin 2611 is inserted into the rivet nut 110. When the pressing device 260 is not performing the pressing operation, the bottom of the pressing block 263 is lower than the bottom of the guide pin 2611. That is, when the pressing device 260 is not performing the pressing operation, the bottom of the pressing block 263 is lower than the bottom of the guide pin 2611. When the mounting seat 262 descends in the vertical direction for the pressing operation, the pressing block 263 first presses against the fixing plate 120. Then, the spring is compressed, and the mounting seat 262 continues to descend in the vertical direction, so that the guide pin 2611 is inserted into the rivet nut 110, and the pressing head 261 presses the rivet nut 110 to deform the rivet nut 110.

[0096] After the pressing operation is completed, the mounting seat 262 rises in the vertical direction, wherein the pressing head 261 first moves toward the side away from the fixing plate 120. During this process, the spring recovers its deformation, while the pressing block 263 still presses on the fixing plate 120, so that the pressing head 261 and the guide pin 2611 arranged at the bottom thereof can be smoothly separated from the rivet nut 110. Afterwards, the pressing block 263 moves together with the mounting seat 262 toward the side away from the fixing plate 120, thereby releasing the pressure on the fixing plate 120.

[0097] Based on the above, this embodiment can prevent the pressing head 261 and / or the guide needle 2611 from driving the rivet nut 110 and the fixing plate 120 to move together during the process of separating the pressing head 261 and the guide needle 2611 arranged at the bottom thereof from the rivet nut 110, thereby ensuring that the pressing head 261 and the guide needle 2611 arranged at the bottom thereof can be smoothly separated from the rivet nut 110.

[0098] It can be understood that, in this embodiment, two pressing heads 261 are provided on the mounting seat 262 to press-fit two rivet nuts 110 respectively.

[0099] In addition, the pressing device 260 also includes a fifth driving member 265, which is used to drive the mounting seat 262 to rise and fall in the vertical direction. The fifth driving member 265 is a booster cylinder. Of course, in other optional embodiments, the fifth driving member 265 can also be other linear driving structures such as ordinary cylinders or electric cylinders. This embodiment does not make specific restrictions on this.

[0100] Furthermore, the pressing device 260 also includes a screw 264, which extends in the vertical direction and is screwed to the mounting seat 262. The bottom of the screw 264 and the bottom of the pressing head 261 are located on the same side of the mounting seat 262. When the mounting seat 262 is descended in the vertical direction for the pressing operation, as the pressing head 261 gradually descends and presses the rivet nut 110, the bottom of the screw 264 can be pressed against the carrier plate 251, thereby preventing the mounting seat 262 from continuing to descend.

[0101] Based on the above, in this embodiment, the height of the bottom of the screw 264 can be adjusted by adjusting the position of the screw 264, thereby adjusting the minimum height of the pressing head 261 during the pressing operation, and then controlling the deformation degree of the rivet nut 110. That is, in this embodiment, the position of the screw 264 can be adjusted to ensure that the deformed part of the rivet nut 110 caused by deformation meets the requirements of subsequent screw installation.

[0102] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
