Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a nail-piercing device. Background Technology

[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and can close, carry, and interrupt current under abnormal circuit conditions within a specified time.

[0003] Currently, circuit breaker housings are typically assembled using rivets, and the rivets can be automatically installed on the housing using a rivet-threading device.

[0004] In related technologies, rivet insertion devices typically include a guiding mechanism, a rivet splitting mechanism, and a rivet pressing mechanism. The guiding pin of the guiding mechanism can first be inserted into the mounting hole of the housing, and then the rivet pressing mechanism pushes the rivet in the rivet splitting mechanism into the mounting hole of the housing. During the process of pushing the rivet into the mounting hole of the housing, the guiding pin also moves out of the mounting hole of the housing. Therefore, the guiding mechanism and the rivet splitting mechanism require high positioning accuracy. However, the guiding mechanism and the rivet splitting mechanism are usually designed separately. To ensure the installation accuracy of the guiding mechanism and the rivet splitting mechanism, a lot of assembly and debugging time may be required. Utility Model Content

[0066] Reference Figures 1 to 16 As shown, this embodiment provides a rivet insertion device, which can be used to insert rivets 20 into the product 10 to be assembled. The product 10 to be assembled has mounting holes 11 for the rivets 20 to pass through.

[0067] The nail-threading device includes a loading platform 110, a support base 200, a guide mechanism 300, a nail-separating mechanism 400, and a nail-pressing mechanism 500. The support base 200 includes a guide member 210. The guide mechanism 300 includes a guide seat 310 slidably connected to the guide member 210, a guide pin 320 fixed to the guide seat 310, and a guide drive member 330 disposed on the support base 200 and connected to the guide seat 310. The guide drive member 330 drives the guide seat 310 to slide and inserts or releases the guide pin 320 into or out of the mounting hole 11 of the product 10 to be assembled on the loading platform 110. The rivet-separating mechanism 400 includes a rivet seat 410 slidably connected to the guide member 210, a positioning drive member 420 disposed on the support base 200 and connected to the rivet seat 410, and a temporary storage structure 430 fixed on the rivet seat 410. The rivet seat 410 is located on the side of the loading platform 110 away from the guide base 310. The positioning drive member 420 is used to drive the rivet seat 410 to press against the product 10 to be assembled on the loading platform 110. The rivet-pressing mechanism 500 is disposed on the rivet seat 410. The rivet-pressing mechanism 500 is used to push out the rivets 20 in the temporary storage structure 430 and insert them into the mounting holes 11 of the product 10 to be assembled.

[0068] In this embodiment, when the rivet-piercing device operates, firstly, the rivet 20 is pierced into the temporary storage structure 430; secondly, the positioning drive 420 is controlled to drive the rivet seat 410 to press against the product to be assembled 10 on the loading platform 110 to position the product to be assembled 10; then, the guide drive 330 is controlled to drive the guide seat 310 to slide so that the guide pin 320 is pierced into the mounting hole 11 of the product to be assembled 10 on the loading platform 110; finally, the rivet-pressing mechanism 500 is controlled to push the rivet 20 out of the temporary storage structure 430 and pierce it into the mounting hole 11 of the product to be assembled 10, and the positioning drive 420 is controlled to drive the rivet seat 410 to reset, so as to complete the rivet 20 piercing. The guide seat 310 and the pin holder 410 are both slidably mounted on the support seat 200 via the guide member 210, which enables the guide seat 310 and the pin holder 410 to have high positioning accuracy. For example, the rivet 20 in the temporary storage structure 430, the product 10 to be assembled that is pressed and positioned by the pin holder 410, and the guide pin 320 have high positioning accuracy, which helps to improve the assembly and debugging time of the pin-threading device.

[0069] In some embodiments, the loading platform 110 may be fixed to the support base 200.

[0070] In other embodiments, such as Figure 2As shown, the loading platform 110 can be mounted on a conveying mechanism. For example, the conveying mechanism includes a cam divider and a turntable 120 connected to the cam divider. The turntable 120 has multiple loading platforms 110 spaced circumferentially. The loading platforms 110 can be conveyed between the guide seat 310 and the pin holder 410 by the conveying device. This is stable and reliable, and helps to improve the automation level of the pin-threading device, making it convenient to place the product 10 to be assembled on the loading platform 110. For example, the loading platform 110 can be provided with a receiving groove 111 for accommodating the product 10 to be assembled, so as to position the product 10 to be assembled.

[0071] For example, the surrounding turntable 120 may be provided with at least one support seat 200, such as two, and each support seat 200 is provided with a guide mechanism 300, a nail-separating mechanism 400 and a nail-pressing mechanism 500, which is beneficial to improving the nail-threading efficiency of the nail-threading device.

[0072] For example, the product to be assembled 10 can be a circuit breaker.

[0073] For example, the product 10 to be assembled is provided with a plurality of mounting holes 11, and the guide pin 320, the temporary storage structure 430 and the mounting holes 11 are arranged in a one-to-one correspondence, which is beneficial to improving the rivet insertion efficiency. In some embodiments, the diameters of the rivets 20 of the product 10 to be assembled can be the same or different. Taking a circuit breaker as an example, it requires four rivets 20 with a diameter of 1.7mm and three rivets 20 with a diameter of 2mm. The mounting hole 11 corresponding to the 1.7mm diameter rivet 20 has a diameter of 1.9mm, and the mounting hole 11 corresponding to the 2mm diameter rivet 20 has a diameter of 2.2mm. This can be accomplished using one set of guide mechanism 300, rivet splitting mechanism 400, and rivet pressing mechanism 500, or it can be accomplished using two sets of guide mechanism 300, rivet splitting mechanism 400, and rivet pressing mechanism 500. For example, one set of guide mechanism 300, rivet splitting mechanism 400, and rivet pressing mechanism 500 is used to pass through the 1.7mm diameter rivet 20, and the other set is used to pass through the 2.2mm diameter rivet 20. Among them, the guide mechanism 300, rivet splitting mechanism 400, and rivet pressing mechanism 500 located on the same support base 200 are considered as one set.

[0074] For example, the positioning drive 420 includes, but is not limited to, a cylinder.

[0075] For example, the guide seat 310 and the pin holder 410 are distributed vertically, that is, the guide seat 310 is located below the loading platform 110, and the pin holder 410 is located above the loading platform 110. It is understood that both the guide seat 310 and the pin holder 410 slide vertically. It is also understood that the guide pin 320 extends vertically.

[0076] For example, such as Figure 4 As shown, the bottom end of the rivet 20 may be provided with a groove 21, and the guide pin 320 may be inserted into the groove 21 at the bottom end of the rivet 20. In some embodiments, after passing through the mounting hole 11 of the product to be assembled 10, the guide pin 320 may pass through the groove 21 at the bottom end of the rivet 20 in the temporary storage structure 430. During at least a period of time, before the rivet 20 passes through the mounting hole 11 in the temporary storage structure 430 and after passing through the mounting hole 11, the guide pin 320 remains inserted in the groove 21 at the bottom end of the rivet 20. That is, the guide pin 320 inserted in the groove 21 at the bottom end of the rivet 20 can guide the rivet 20 to pass through the mounting hole 11 of the product to be assembled, thereby reducing the risk of the rivet 20 colliding with or even failing to pass through the product to be assembled 10.

[0077] For example, the guide pin 320 can be stepped, and the top of the small end of the guide pin 320 is conical, which is conducive to the small end of the guide pin 320 being inserted into the groove 21 at the bottom end of the rivet 20.

[0078] For example, the small end diameter d1 of the guide pin 320 is larger than the groove diameter d2 of the bottom end of the rivet 20.

[0079] For example, the large end diameter d3 of the guide pin 320 is greater than the diameter d4 of the rivet 20, but smaller than the diameter d5 of the mounting hole 11 of the product 10 to be assembled.

[0080] For example, after the guide pin 320 is inserted into the groove 21 at the bottom of the rivet 20 and guides the rivet 20 into the mounting hole 11 to a certain depth, it indicates that the rivet 20 of the product to be assembled 10 has been inserted. In this process, the rivet 20 will automatically fall down under its own weight, and the subsequent riveting process will press the rivet 20 that has not fully entered the mounting hole 11 into place completely.

[0081] In this embodiment, reference is made to Figure 1 and Figure 5 As shown, the rivet holder 410 is provided with multiple positioning blocks 440, which can press the rivet holder 410 against the product 10 to be assembled on the loading platform 110. The positioning blocks 440 have stepped side faces 441 and stepped end faces 442 arranged at an angle, for example, the stepped side faces 441 and the stepped end faces 442 are perpendicular to each other. The stepped end faces 442 of the positioning blocks 440 can abut against the product 10 to be assembled, and the product 10 to be assembled is located between the stepped side faces 441 of the multiple positioning blocks 440. It is understood that when the rivet holder 410 is pressed against the product 10 to be assembled on the loading platform 110, the stepped end faces 442 of the positioning blocks 440 abut against the product 10 to be assembled, and the product 10 to be assembled is located between the stepped side faces 441 of the multiple positioning blocks 440, which helps to improve the positioning accuracy of the product 10 to be assembled and reduces the risk of the rivet 20 failing to pass through the mounting hole 11.

[0082] For example, four, five or six positioning blocks 440 are provided to ensure the positioning accuracy of the product 10 to be assembled.

[0083] In this embodiment, reference is made to Figure 1 , Figure 6 and Figure 7 As shown, the guide member 210 can be configured as an optical axis, and at least two guide members 210 are provided. Exemplarily, the guide member 210 extends in a vertical direction.

[0084] For example, the support base 200 further includes a support body 220, a top plate 230 fixed to the support body 220, and a bottom plate 240. The guide member 210 can be connected to the top plate 230 via a first screw connector 211, for example, the first screw connector 211 passes through the top plate 230 and is threadedly connected to the top end of the guide member 210. The guide member 210 can be connected to the bottom plate 240 via a second screw connector 212, for example, the bottom plate 240 has a hole or groove for the bottom end of the guide member 210 to be inserted into, and the second screw connector 212 is threadedly connected to the bottom plate 240 and abuts against the periphery of the bottom end of the guide member 210. The positioning drive member 420 can be disposed on the top plate 230 or on the top end of the support body 220, for example, connected to the support body 220 via a fixing plate 221, the fixing plate 221 being located above the top plate 230.

[0085] For example, the guide seat 310 is provided with a first sliding sleeve 311, which is provided in a one-to-one correspondence with the guide member 210. The first sliding sleeve 311 is sleeved on the corresponding guide member 210, which facilitates the positioning and assembly of the guide seat 310, and the sliding of the guide seat 310 relative to the support seat 200 is stable and reliable. The first sliding sleeve 311 can be a linear bearing.

[0086] For example, the pin holder 410 is provided with a second sliding sleeve 450, which is provided in a one-to-one correspondence with the guide member 210, and the second sliding sleeve 450 is sleeved on the corresponding guide member 210, which facilitates the positioning and assembly of the pin holder 410, and the sliding of the pin holder 410 relative to the support base 200 is stable and reliable. The second sliding sleeve 450 can be a linear bearing.

[0087] Of course, the guide component 210 can also be a slide rail or other guide structure, which is not limited in this embodiment.

[0088] In this embodiment, reference is made to Figure 6 and Figure 8As shown, the support base 200 is also provided with a positioning plate 250, and the positioning plate 250 is provided with a first guide sleeve 251, through which the guide pin 320 passes. The positioning plate 250 is located between the material carrier 110 and the guide base 310. In this embodiment, the first guide sleeve 251 provides support for the guide pin 320, which helps to reduce the risk of the guide pin 320 bending or breaking.

[0089] Understandably, the first sliding sleeve 311 has a relatively long extension length. In one feasible embodiment, the positioning plate 250 is provided with a first clearance hole 312, and the first sliding sleeve 311 passes through the first clearance hole 312, which helps to improve the structural compactness of the nail-piercing device. The first clearance hole 312 and the first sliding sleeve 311 are provided in a one-to-one correspondence.

[0090] In one feasible implementation, the positioning plate 250 is provided with positioning holes (not shown), which are stepped holes. The first guide sleeve 251 is a T-shaped sleeve, which passes through the positioning hole. The positioning holes and the first guide sleeves 251 are arranged in a one-to-one correspondence. In this embodiment, the first guide sleeve 251 can be pressed into the positioning hole by a third screw connector 252. For example, each first guide sleeve 251 corresponds to at least two third screw connectors 252. The third screw connectors 252 are threadedly connected to the positioning plate 250, and the head of the third screw connector 252 abuts against the large end of the corresponding first guide sleeve 251 along the extension direction of the guide pin 320. The large end of the positioning hole can face the guide seat 310.

[0091] In one feasible implementation, the guide drive 330 is located on the side of the support body 220 away from the guide pin 320, which helps to improve the structural compactness of the pin-piercing device.

[0092] For example, the guide seat 310 may be plate-shaped, and the guide seat 310 is provided with a second clearance hole 253, through which the support body 220 passes.

[0093] In this embodiment, reference is made to Figure 7 , Figures 9 to 14As shown, the rivet-separating mechanism 400 also includes a dropping structure 460, a transferring structure 470, and a transferring drive 480. The dropping structure 460 is mounted on the rivet-separating seat 410. The transferring structure 470 is slidably mounted on the rivet-separating seat 410 and has a receiving position and a dropping position relative to the rivet-separating seat 410. The transferring drive 480 is mounted on the rivet-separating seat 410 and connected to the transferring structure 470. The transferring drive 480 drives the transferring structure 470 to slide between the receiving position and the dropping position. When the transferring structure 470 is located at the receiving position, the rivets 20 in the dropping structure 460 can fall into the transferring structure 470; when the transferring structure 470 is located at the dropping position, the rivets 20 in the transferring structure 470 can fall into the temporary storage structure 430. In conjunction with the transferring drive 480, the automatic, stable, and reliable feeding of rivets 20 into the temporary storage structure 430 can be achieved. Understandably, rivet 20 can fall into the transfer structure 470 and the temporary storage structure 430 by its own weight.

[0094] For example, the material feeding structure 460 and the temporary storage structure 430 are set up in a one-to-one correspondence.

[0095] For example, the material transfer drive 480 includes, but is not limited to, a cylinder.

[0096] In some embodiments, when the transfer structure 470 is in the dropping position, the rivet pressing mechanism 500 pushes out the rivet 20 in the temporary storage structure 430 and inserts it into the mounting hole 11 of the product 10 to be assembled. In other embodiments, when the transfer structure 470 is in the receiving position, the rivet pressing mechanism 500 pushes out the rivet 20 in the temporary storage structure 430 and inserts it into the mounting hole 11 of the product 10 to be assembled.

[0097] In this embodiment, reference is made to Figure 7 , Figures 9 to 11 As shown, the staple holder 410 includes a first mounting plate 411 and a second mounting plate 412 arranged at intervals along the vertical direction. The first mounting plate 411 is located above the second mounting plate 412. The material dropping structure 460 is disposed on the first mounting plate 411, the temporary storage structure 430 is disposed on the second mounting plate 412, and the material transfer structure 470 is slidably disposed between the first mounting plate 411 and the second mounting plate 412. The structure is compact.

[0098] For example, when the positioning drive 420 is a cylinder, the piston rod of the positioning drive 420 can be connected to the first mounting plate 411.

[0099] For example, the positioning block 440 may be located at the bottom of the second mounting plate 412.

[0100] For example, the material transfer structure 470 can be slidably mounted on the second mounting plate 412 via a slide rail slider structure.

[0101] For example, the second sliding sleeve 450 may be disposed on the second mounting plate 412.

[0102] In one feasible implementation, the bottom end of the rivet 20 located within the transfer structure 470 abuts against the top surface of the second mounting plate 412, and the top end of the rivet 20 within the transfer structure 470 protrudes from the top of the transfer structure 470 and is located outside the dropping structure 460. It is understood that multiple rivets 20 can be installed within the dropping structure 460, and the bottom end of the upper rivet 20 of two adjacent rivets 20 abuts against the top end of the lower rivet 20. In this embodiment, the top end of the rivet 20 within the transfer structure 470 protrudes from the top of the transfer structure 470 and is located outside the dropping structure 460; that is, when the transfer structure 470 moves towards the dropping position, the rivets 20 within the dropping structure 460 and the transfer structure 470 will not interfere with each other, ensuring stability and reliability.

[0103] For example, when the bottom end of the rivet 20 located in the transfer structure 470 abuts against the top surface of the second mounting plate 412, the top end of the rivet 20 located in the transfer structure 470 protrudes from the top of the transfer structure 470 by a dimension h1 of 0.2mm-1mm, such as 0.3mm, 0.5mm or 0.6mm.

[0104] In one feasible implementation, the top of the temporary storage structure 430 is set lower than the top surface of the second mounting plate 412 to prevent positional interference between the temporary storage structure 430 and the transfer structure 470 and the rivets 20 within the transfer structure 470, ensuring stability and reliability.

[0105] For example, the top of the temporary storage structure 430 is 0.1mm-0.8mm lower than the top surface of the second mounting plate 412 by a dimension h2, such as 0.2mm, 0.3mm or 0.5mm.

[0106] In one feasible embodiment, the pin holder 410 further includes a first limiting plate 413 and a second limiting plate 414. The top of the first limiting plate 413 is connected to the first mounting plate 411, and the bottom of the first limiting plate 413 is connected to the second mounting plate 412; the top of the second limiting plate 414 is connected to the first mounting plate 411, and the bottom of the second limiting plate 414 is connected to the second mounting plate 412. Along the sliding direction of the transfer structure 470, the transfer structure 470 is located between the first limiting plate 413 and the second limiting plate 414. The transfer structure 470 located at the receiving position abuts against the first limiting plate 413, and the transfer structure 470 located at the dropping position abuts against the second limiting plate 414, so as to realize the positioning of the transfer structure 470. This is beneficial to improve the stability of transferring the rivets 20 in the dropping structure 460 to the temporary storage structure 430 through the transfer structure 470. In addition, the first limiting plate 413 and the second limiting plate 414, together with the first mounting plate 411 and the second mounting plate 412, can make the rivet seat 410 have good structural stability.

[0107] For example, the first limiting plate 413 can be connected to the first mounting plate 411 and the second mounting plate 412 by means of bolt fastening.

[0108] For example, the second limiting plate 414 can be connected to the first mounting plate 411 and the second mounting plate 412 by means of bolt fastening.

[0109] For example, both the first mounting plate 411 and the second mounting plate 412 are provided with a first positioning groove 4101 for the second limiting plate 414 to be inserted into, which helps to improve the positioning and assembly accuracy of the first mounting plate 411 and the second mounting plate 412 along the first direction and helps to improve the structural stability of the pin holder 410. The shape of the first positioning groove 4101 can be U-shaped.

[0110] For example, the first mounting plate 411 or the second mounting plate 412 is provided with a second positioning groove 4102 for the first limiting plate 413 to be inserted into, which is beneficial to improving the positioning and assembly accuracy of the first limiting plate 413 and improving the structural stability of the pin holder 410. The shape of the second positioning groove 4102 can be U-shaped.

[0111] For example, the first limiting plate 413 is provided with a first notch 4103 for insertion of the first mounting plate 411 and a second notch (not shown) for insertion of the second mounting plate 412. This is beneficial for improving the positioning and assembly accuracy of the first mounting plate 411 and the second mounting plate 412 along the second direction, and for improving the structural stability of the pin holder 410. The first and second directions are perpendicular to each other. The first direction can be the length direction of the pin holder 410, and the second direction can be the width direction of the pin holder 410. The first, second, and vertical directions can be perpendicular to each other. The shapes of the first notch 4103 and the second notch can be U-shaped.

[0112] In one feasible implementation, the nail-separating mechanism 400 includes at least one material transfer structure 470, and a material transfer drive member 480 is provided in a one-to-one correspondence with the material transfer structure 470. Each material transfer structure 470 corresponds to at least one material dropping structure 460 and at least one temporary storage structure 430. In some embodiments, a first limiting plate 413 may also be provided in a one-to-one correspondence with the material transfer structure 470.

[0113] For example, there are two of each of the material transfer structure 470, the material transfer drive member 480, and the first limiting plate 413, with the second limiting plate 414 located between the two first limiting plates 413. For example, the material transfer drive member 480 can be disposed on the corresponding first limiting plate 413. The two material transfer structures 470 can slide towards or away from each other along a first direction.

[0114] In this embodiment, reference is made to Figure 9 , Figure 12 and Figure 13 As shown, the temporary storage structure 430 includes a temporary storage block 431 fixed to the pin holder 410, at least two stops 432 movably disposed on the temporary storage block 431, and a reset elastic member 433 disposed between the stops 432 and the pin holder 410. The temporary storage block 431 has a temporary storage hole 4311, and the stops 432 have a stop portion 4321. It can be understood that both the guide mechanism 300 and the pin-dispensing mechanism 400 are slidably connected to the support base 200 through the guide member 210, which is beneficial to improving the positioning accuracy between the temporary storage hole 4311 and the guide pin 320, and to reducing the assembly and debugging time of the pin-piercing device. The temporary storage hole 4311 can extend vertically.

[0115] For example, under the action of the reset elastic member 433, the temporary storage block 431 can stop the rivet 20 in the temporary storage hole 4311 from sliding towards the loading table 110, so as to prevent the rivet 20 from accidentally falling out of the temporary storage structure 430 due to its own weight. Among them, the stop portions 4321 of all the blocks 432 can abut against each other.

[0116] For example, the rivet pressing mechanism 500 can push the stop portion 4321 away from each other through the rivet 20 in the temporary hole 4311, so that the rivet 20 can be disengaged from the temporary structure 430 and pass into the mounting hole 11 of the product 10 to be assembled under the pushing of the rivet pressing mechanism 500, which is stable and reliable.

[0117] For example, the reset elastic element 433 can be a spring.

[0118] For example, the top of the temporary storage hole 4311 is provided with an inner chamfer, which facilitates the rivet 20 falling into the temporary storage hole 4311.

[0119] For example, the top of the temporary storage block 431 has a temporary storage extension post 4312, and the temporary storage hole 4311 penetrates the top of the temporary storage extension post 4312. The top of the unloading block 4621 is in contact with the bottom surface of the second mounting plate 412, and the temporary storage extension post 4312 passes through the second mounting plate 412. It is understood that the top of the temporary storage extension post 4312 is lower than the top surface of the second mounting plate 412; for example, the length of the temporary storage extension post 4312 is 11.8 mm, and the thickness of the second mounting plate 412 is 12 mm.

[0120] For example, the stop portion 4321 is provided with a concave surface 4322. When the stop portions 4321 of all the stops 432 abut against each other, a stop hole is formed between all the concave surfaces 4322. It is understood that the concave surface 4322 on the stop portion 4321 can prevent the rivet 20 from sliding down toward the loading table 110. It is understood that the minimum diameter of the stop hole is smaller than the diameter of the rivet 20.

[0121] For example, the stop hole includes a frustum-shaped section and a straight section. The small end of the frustum-shaped section communicates with the straight section, and the small end of the frustum-shaped section faces the guide pin 320. The diameter of the small end of the frustum-shaped section is equal to the diameter of the straight section. Taking a rivet 20 diameter d4 of 1.7 mm as an example, the diameter d6 of the straight section can be set to 1.5 mm.

[0122] For example, the temporary storage block 431 is provided with a relief groove 4313, which can accommodate at least a portion of the stop block 432, and has a compact structure.

[0123] For example, the stop block 432 can be rotatably mounted on the temporary storage block 431 via a pin.

[0124] In this embodiment, reference is made to Figure 9As shown, the material feeding structure 460 includes a material feeding tube 461, a material feeder 462 connected to the discharge end of the material feeding tube 461, and a material feeding sensor 463 disposed on the material feeder 462. The material feeder 462 is fixed on the rivet seat 410. The rivets 20 in the material feeding tube 461 can fall through the material feeder 462 into the material transfer structure 470 located at the receiving position. The material feeding sensor 463 is used to detect whether there are rivets 20 in the material feeder 462. In this embodiment, the feeding end of the feeding tube 461 is used to feed rivets 20 and can be connected to a vibratory feeder. The rivets 20 in the vibratory feeder slide into the feeding tube 461 according to the desired position. Under the action of gravity, the rivets 20 slide down from the feeding tube 461 into the feeder 462 and are detected by the feeding sensor 463. At this time, the transfer structure 470 can first move to the receiving position to receive the rivets 20, and then move to the feeding position so that the rivets 20 fall into the temporary storage structure 430, ensuring stability and reliability. In some embodiments, the feeding sensor 463 can be used to detect whether any rivets 20 have fallen into the transfer structure 470.

[0125] Exemplarily, the feeder 462 includes a feed block 4621 and a first quick-connect pipe connector 4622 connected to the feed block 4621. The bottom end of the feed block 4621 has a feed extension post 46211, and the feed block 4621 is provided with a feed hole 46212, which penetrates the top end of the feed block 4621 and the feed extension post 46211. The first quick-connect pipe connector 4622 is connected to the discharge end of the feed pipe 461, and the discharge end of the feed pipe 461 communicates with the feed hole 46212. A feed sensor 463 is disposed around the feed extension post 46211. In this embodiment, the feed block 4621 is disposed on the top surface of the first mounting plate 411, the bottom end of the feed block 4621 is in contact with the top surface of the first mounting plate 411, and the feed extension post 46211 passes through the first mounting plate 411. Among them, the material discharge hole 46212 can be extended in the vertical direction.

[0126] For example, the material feeding sensor 463 can be configured as a photoelectric sensor.

[0127] For example, the discharge tube 461 can be configured as a transparent tube.

[0128] In this embodiment, reference is made to Figure 7 and Figure 9As shown, the transfer structure 470 includes a transfer plate 471 slidably connected to the rivet holder 410 and a transfer block 472 fixed to the side of the transfer plate 471 away from the feeder 462. For example, the transfer block 472 is located at the bottom of the transfer plate 471. The transfer plate 471 has a first transfer hole 4711, and the transfer block 472 has a second transfer hole 4721 communicating with the first transfer hole 4711. The first transfer hole 4711 and the second transfer hole 4721 are used to accommodate the rivet 20. It can be understood that when the rivet 20 is located inside the transfer structure 470, the top end of the rivet 20 protrudes from the first transfer hole 4711, and the bottom end of the rivet 20 protrudes from the second transfer hole 4721. It is understood that the rivets 20 in the feeder 462 can fall into the first transfer hole 4711 and the second transfer hole 4721, and the rivets 20 in the first transfer hole 4711 and the second transfer hole 4721 can fall into the temporary storage hole 4311 of the temporary storage block 431. Both the first transfer hole 4711 and the second transfer hole 4721 can extend vertically. In this embodiment, the transfer structure 470 is designed as a separate unit, which helps to save materials and improve the structural compactness of the rivet-separating mechanism 400.

[0129] It is understandable that when the transfer structure 470 is moved to the dropping position, the rivet 20 in the dropping structure 460 abuts against the top surface of the transfer plate 471, which is conducive to the rivet 20 falling into the first transfer hole 4711 and the second transfer hole 4721 when the transfer structure 470 is moved back to the receiving position.

[0130] For example, the diameter of the first transfer hole 4711 is larger than the diameter of the second transfer hole 4721. The top end of the second transfer hole 4721 is provided with an inner chamfer to make the transition between the first transfer hole 4711 and the second transfer hole 4721 smooth, which is conducive to the rivet 20 falling into the first transfer hole 4711 and the second transfer hole 4721.

[0131] For example, the top of the transfer block 472 is provided with a transfer extension post (not shown), which is inserted into the transfer plate 471, which is beneficial for the positioning and assembly between the transfer plate 471 and the transfer block 472.

[0132] For example, the transfer block 472 can be connected to the transfer plate 471 by means of bolt fastening.

[0133] For example, the transfer block 472, the feeder 462, and the temporary storage structure 430 are configured in a one-to-one correspondence.

[0134] For example, the nail splitting mechanism 400 includes two material transfer structures 470, that is, the nail splitting mechanism 400 includes two material transfer plates 471, and each material transfer plate 471 is provided with at least one material transfer block 472. It can be understood that the first material transfer hole 4711 and the second material transfer hole 4721 correspond one-to-one.

[0135] In one feasible implementation, when the bottom end of the rivet 20 located in the transfer structure 470 abuts against the top surface of the second mounting plate 412, the top end of the rivet 20 located in the transfer structure 470 protrudes beyond the top of the transfer structure 470 by a dimension smaller than the distance between the bottom end of the dropping extension column 46211 and the top surface of the transfer plate 471, so as to prevent the rivets 20 in the dropping structure 460 and the rivets 20 in the transfer structure 470 from interfering with the transfer structure 470's transfer from the receiving position to the dropping position.

[0136] For example, the distance h3 between the bottom end of the material dropping extension column 46211 and the top surface of the transfer plate 471 can be 0.5mm-2mm, such as 0.7mm, 1mm or 1.5mm.

[0137] In this embodiment, reference is made to Figures 14 to 16 As shown, the rivet clamping mechanism 500 includes a rivet clamping seat 510, a rivet clamping pin 520, and a clamping drive 530. The rivet clamping seat 510 is slidably connected to the rivet distributor seat 410; the rivet clamping pin 520 is disposed on the rivet clamping seat 510; the clamping drive 530 is disposed on the rivet distributor seat 410 and connected to the rivet clamping seat 510. The clamping drive 530 drives the rivet clamping seat 510 to slide and pushes the rivet 20 within the temporary storage structure 430 through the rivet clamping pin 520, ensuring stability and reliability.

[0138] For example, the pin 520, guide pin 320 and temporary storage structure 430 are set in a one-to-one correspondence, so that the pin insertion of the product 10 to be assembled can be completed in one go.

[0139] For example, the pressure drive 530 includes, but is not limited to, a cylinder.

[0140] For example, the pressure pin seat 510 may be plate-shaped.

[0141] In this embodiment, reference is made to Figure 3 As shown, the rivet seat 510 is provided with a limiting member 550. When the limiting member 550 abuts against the piston rod of the guide seat 310 or the guide drive member 330 which is a cylinder, the rivet 20 is clamped between the guide pin 320 and the rivet pin 520.

[0142] In one feasible implementation, when the guide seat 310 abuts against the limiting member 550, the pressure pin 520 abuts against the top of the rivet 20, and the guide pin 320 is inserted into the groove 21 at the bottom of the rivet 20.

[0143] In another feasible embodiment, the guide drive 330 is configured as a cylinder. The first end of the piston rod of the guide drive 330 is connected to the guide seat 310. When the second end of the piston rod of the guide drive 330 abuts against the limiting member 550, the pressure pin 520 abuts against the top of the rivet 20, and the guide pin 320 is inserted into the groove 21 at the bottom end of the rivet 20. It can be understood that the cylinder body of the guide drive 330 is fixed on the support base 200. Of course, the guide drive 330 can also be configured as other drive components, such as a hydraulic cylinder, which is not limited in this embodiment.

[0144] Understandably, during the process of the rivet 20 being pushed out of the temporary storage structure 430 and inserted into the mounting hole 11 of the product to be assembled by the rivet pressing mechanism 500, as the rivet 20 extends into the mounting hole 11, the guide pin 320 exits the mounting hole 11. During this process, the guide pin 320 can always be inserted into the groove 21 at the bottom end of the rivet 20, or it can disengage from the groove 21 at the bottom end of the rivet 20 after the rivet 20 has been inserted into the mounting hole 11 to a certain depth. That is, the guide seat 310 abuts against the limiting member 550, or the second end of the piston rod of the guide drive member 330 abuts against the limiting member 550. This can at least accompany the initial process of the rivet 20 penetrating the mounting hole 11, that is, the process of the rivet 20 not penetrating into the mounting hole 11 and the process of just penetrating into the mounting hole 11. While guiding the rivet 20 into the mounting hole 11, it is beneficial to reduce the force of the guide pin 320 and the rivet pressing pin 520 pressing the rivet 20, making it stable and reliable.

[0145] In this embodiment, the position of the limiting member 550 along the sliding direction of the rivet seat 510 is adjustable, which can improve the applicability of the rivet insertion device, for example, it can be used to insert rivets 20 of different lengths into the product 10 to be assembled.

[0146] For example, the pressure pin seat 510 is provided with an extension plate 511, and the limiting member 550 is provided on the extension plate 511. It can be understood that the limiting member 550 can be placed on the side of the support body 220 where the guide drive member 330 is provided by the extension plate 511.

[0147] For example, the limiting member 550 can be threaded onto the extension plate 511. The limiting member 550 can be a bolt. A first fastening sleeve 560 can be threaded onto the limiting member 550, and the first fastening sleeve 560 abuts against the extension plate 511 to improve the connection stability of the limiting member 550.

[0148] Understandably, when the nail-piercing device is in operation, the nail-pressing seat 510 descends first. When the guide seat 310 abuts against the limiting member 550, or when the second end of the piston rod of the guide drive member 330 abuts against the limiting member 550, the guide seat 310 descends together with the nail-pressing seat 510.

[0149] In one feasible implementation, when both the guide drive 330 and the pressing drive 530 are cylinders, the extension speed of the piston rod of the guide drive 330 is less than or equal to the extension speed of the piston rod of the pressing drive 530. It is understood that, at least initially, during the process of the rivet 20 passing through the mounting hole 11, the guide pin 320 will not disengage from the groove 21 at the bottom end of the rivet 20. Exemplarily, after the guide seat 310 abuts against the limiting member 550, or after the second end of the piston rod of the guide drive 330 abuts against the limiting member 550, the extension speed of the piston rod of the guide drive 330 is equal to the extension speed of the piston rod of the pressing drive 530. This allows the guide seat 310 and the pressing pin seat 510 to descend synchronously, ensuring that the force with which each set of pressing pins 520 and guide pins 320 clamps the corresponding rivet 20 is moderate, which helps reduce the risk of the rivet 20 colliding with or even failing to be assembled with the product 10 during insertion. It is understandable that the extension speed of the piston rod of the guide drive 330 is equal to the extension speed of the piston rod of the pressure drive 530, and the limiting member 550 can apply a downward thrust to the piston rod of the guide drive 330, or the force between the limiting member 550 and the piston rod of the guide drive 330 is zero.

[0150] In one feasible implementation, a second guide sleeve 415 is provided on the first mounting plate 411, and the pressure pin 520 passes through the second guide sleeve 415. In this embodiment, the second guide sleeve 415 provides support for the guide pin 320, which helps to reduce the risk of bending or breaking of the pressure pin 520. The way in which the second guide sleeve 415 is installed on the first mounting plate 411 is the same as the way the first guide sleeve 251 is installed on the positioning plate 250, and will not be described in detail in this embodiment.

[0151] In one feasible embodiment, the staple holder 410 further includes a third mounting plate 416, which is disposed on the side of the first mounting plate 411 away from the second mounting plate 412, for example, the third mounting plate 416 is located above the first mounting plate 411. The pressure drive 530 may be disposed on the third mounting plate 416. Exemplarily, the staple holder 410 also includes at least two supporting optical shafts 417, for example, four, with the top end of the supporting optical shafts 417 connected to the third mounting plate 416 and the bottom end of the supporting optical shafts 417 connected to the first mounting plate 411. The supporting optical shafts 417 can be connected to the first mounting plate 411 and the third mounting plate 416 by bolt fastening, facilitating assembly. For example, the pressure pin holder 510 is provided with a third sliding sleeve 512, which is arranged in a one-to-one correspondence with the support optical shaft 417. The third sliding sleeve 512 is sleeved on the corresponding support optical shaft 417 to realize the sliding connection between the pressure pin holder 510 and the pin holder 410, which is stable and reliable. The third sliding sleeve 512 can be a linear bearing.

[0152] For example, the discharge pipe 461 passes through the third mounting plate 416. In order to ensure that the section of the discharge pipe 461 between the first mounting plate 411 and the third mounting plate 416 has a high degree of straightness so as to facilitate the slippage of the rivet 20, the third mounting plate 416 is provided with a second quick-connect pipe connector 418, and the discharge pipe 461 passes through the second quick-connect pipe connector 418.

[0153] In one feasible embodiment, the pin holder 510 is provided with a limiting hole 513, which is a stepped hole. The top end of the pin 520 is provided with a positioning boss 521. The pin 520 passes through the limiting hole 513, and the positioning boss 521 is located inside the larger end of the limiting hole 513. The pin-pressing mechanism 500 also includes a pressing elastic member 540, which is located inside the limiting hole 513 and abuts against the positioning boss 521. The pressing elastic member 540 causes the positioning boss 521 to tend to abut against the stepped surface of the limiting hole 513. The smaller end of the limiting hole 513 faces the guide seat 310. In this embodiment, the setting of the pressure elastic element 540 allows the pressure pin 520 to have a certain amount of movement along its own extension direction, so as to compensate for the length error of the rivet 20, the pressure pin 520 and the guide pin 320. During at least a period of the process when the rivet 20 is inserted into the product 10 to be assembled under the push of the pressure pin 520, the guide pin 320 remains inserted in the groove 21 at the bottom end of the rivet 20, which helps to reduce the risk of the rivet 20 colliding with or even failing to be assembled with the product 10 during insertion.

[0154] Understandably, when the guide seat 310 abuts against the limiting member 550, or when the second end of the piston rod of the guide drive member 330 abuts against the limiting member 550, the setting of the pressing elastic member 540 is beneficial to improving the stability of all groups of pressing pins 520 and guide pins 320 clamping the corresponding rivets 20, and is beneficial to reducing the risk of the rivets 20 colliding with or even failing to be assembled with the product 10 when they are inserted.

[0155] For example, the maximum pressure of the pressure elastic element 540 on the pressure pin 520 is 30.6 N.

[0156] For example, the pressure pin 520 has a movement allowance of 0.3mm-1mm along its own extension direction, such as 0.5mm or 0.6mm.

[0157] For example, the pressure elastic element 540 can be configured as a spring plunger. The spring plunger can be threadedly connected to the pressure pin seat 510, meaning the position of the spring plunger is adjustable, and the pressure pin 520 has adjustable range of motion along its extension direction. For example, to improve the connection stability of the spring plunger, a second fastening sleeve 541 is threadedly connected to the spring plunger, and the second fastening sleeve 541 abuts against the pressure pin seat 510 along the extension direction of the pressure pin 520.

[0158] In this embodiment, the operation process of the nail-piercing device is as follows:

[0159] S100, the control positioning drive 420 drives the pin holder 410 to move down, so that the positioning block 440 presses against the product 10 to be assembled on the loading table 110.

[0160] S200 First, after the rivet 20 in the unloading structure 460 falls into the transfer structure 470, the transfer drive 480 is controlled to push the transfer structure 470 to the unloading position, and the rivet 20 in the transfer structure 470 falls into the temporary storage structure 430; then, the transfer drive 480 is controlled to push the transfer structure 470 to the receiving position.

[0161] Steps S100 and S200 are performed sequentially.

[0162] S300, the control guide drive 330 drives the guide seat 310 to move upward, and the guide pin 320 passes through the mounting hole 11 of the product 10 to be assembled on the loading platform 110.

[0163] S400, the control pressure drive 530 drives the nail holder 510 to move down, the nail pin 520 pushes against the rivet 20 in the temporary storage structure 430 until the limit member 550 abuts against the second end of the piston rod of the guide drive 330, the control guide drive 330 drives the guide seat 310 to move down synchronously with the nail holder 510, and the nail insertion operation of the product to be installed is completed.
