[0048] In recent years, with the rapid development of the kitchenware industry, the demand for commercial and household soup pot products has been increasing. The pot body of soup pot products has a relatively large volume. Currently, the maximum diameter of the pot body in the market can reach 600 mm, and the maximum height can reach 600 mm, making the overall mass relatively heavy when filled with soup ingredients. Welding only the pot ears is far from sufficient in terms of strength. Therefore, it is also necessary to rivet and strengthen the pot body and the pot ears to enhance the connection strength between the pot ears and the pot body.

[0049] In traditional technologies, it is necessary to manually rivet and strengthen the pot body and the pot ears through manual work or a riveting press, resulting in low production efficiency and low overall automation. Moreover, at least two people are required to cooperate with each other to complete the riveting process, consuming a large amount of human resources.

[0050] Based on the above concepts and problems, the present invention proposes a riveting device 100. It can be understood that the riveting device 100 is used for riveting soup pot 7 products, that is, riveting pot ears, pot handles or other components to the pot body. The riveting device 100 positions and fixes the soup pot 7 through the positioning mechanism 2. The positioning device also has the function of fixing and abutting the rivet 6. Through the pressing combination of the riveting mechanism 3 and the positioning mechanism 2, the riveting of the pot body and the pot ears and pot handles of the soup pot 7 is completed. The riveting device 100 is also provided with a feeding device 5 for automatic feeding and a feeding device 4 for conveying the rivets 6 to the positioning mechanism 2, effectively improving the production efficiency and the overall automation degree and saving labor costs.

[0051] Please refer to Figures 1 to 8 As shown, in the embodiment of the present invention, the riveting device 100 is used for riveting the soup pot 7. The riveting device 100 includes a machine body 1, a positioning mechanism 2, a riveting mechanism 3 and a feeding device 4. The machine body 1 forms an installation surface 11. A rotatable rotating platform 111 is provided on the installation surface 11. The positioning mechanism 2 includes a positioning block 21 and a plurality of positioning components 22. The positioning block 21 is detachably arranged on the rotating platform 111. The plurality of positioning components 22 are symmetrically installed on the periphery of the positioning block 21. The positioning components 22 are used for placing the rivets 6. One end of the plurality of positioning components 22 away from the positioning block 21 abuts against the inner wall of the soup pot 7, and the rivets 6 pass through the soup pot 7. The riveting mechanism 3 includes a riveting head 31 and a first driving member 32. The first driving member 32 is installed on the installation surface 11. The output end of the first driving member 32 is connected to the riveting head 31 to drive the riveting head 31 to approach the soup pot 7 and press against the rivets 6 penetrating the soup pot 7. The feeding device 4 is slidably arranged on the installation surface 11. The feeding device 4 is arranged adjacent to the positioning mechanism 2 and is used for conveying the rivets 6 to the positioning components 22.

[0052] In this embodiment, as Figure 1As shown in the figure, the body 1 is a structural support component of the riveting device 100, which is used to install and fix the positioning mechanism 2, the riveting mechanism 3 and the feeding device 4. The body 1 can be a base, a mounting frame, a frame, etc., which is not limited here. One side of the body 1 forms a mounting surface 11. The mounting surface 11 is parallel to the ground on which the body 1 is placed. A rotatable rotating platform 111 is provided on the mounting surface 11. On the side of the mounting surface 11 facing away from the rotating platform 111, a driving member for driving the rotation of the rotating platform 111 is provided. The rotating platform 111 and the driving member are connected by gear transmission. A slidable feeding device 4 is also provided on the mounting surface 11, and the feeding device 4 can slide to the side adjacent to the positioning mechanism 2.

[0053] It can be understood that the setting of the rotating platform 111 can drive the positioning assembly 22 to rotate through the positioning block 21. A rivet 6 is placed in the positioning assembly 22, and the rivet 6 is transferred to the positioning assembly 22 through the feeding device 4; when the positioning assembly 22 needs to be replenished with rivets 6, the rotating platform 111 rotates to make the positioning assembly 22 face the feeding assembly, so as to facilitate the feeding assembly to transfer the rivets 6 to the positioning assembly 22. At the same time, when multiple rivets 6 need to be riveted on the soup pot 7, after the positioning assembly 22 and the riveting mechanism 3 complete the riveting of one group, the rotation of the rotating platform 111 can drive the positioning assembly 22 to reach another group of positions to be riveted for riveting. Furthermore, the rotation of the rotating platform 111 drives the positioning assembly 22 to rotate continuously to complete all the riveting. The setting of the rotating platform 111 effectively improves the processing efficiency and automation degree of the riveting device 100 compared with the prior art of manually transferring the soup pot 7 and manually riveting.

[0054] In this embodiment, as Figures 1 to 3 shown, the positioning block 21 is detachably installed on the side of the rotating platform 111 facing away from the mounting surface 11. The positioning block 21 and the rotating platform 111 can be connected by clamping, bolt connection, pin connection, etc., which is not limited here. A plurality of positioning assemblies 22 are installed on the periphery of the positioning block 21, and one end of the plurality of positioning assemblies 22 away from the positioning block 21 abuts against the inner wall of the soup pot 7.

[0055] It can be understood that the positioning block 21 can be replaced with different sizes to fit saucepans 7 with different inner diameters. The cross-sectional shape of the positioning block 21 can be polygonal, or it can be a circular or elliptical shape with a curvature, which is not limited here. Preferably, for the convenience of installing the positioning component 22 on the positioning block 21, the positioning block 21 is selected as polygonal, so that each positioning component 22 can be installed on the edge of the polygon of the positioning block 21, so as to improve the connection tightness between the positioning component 22 and the positioning block 21, and at the same time facilitate the installation and disassembly of the positioning component 22. One end of multiple positioning components 22 away from the positioning block 21 jointly forms an abutting surface, and the abutting surface abuts against the inner wall of the saucepan 7, so that multiple positioning components 22 jointly abut against it inside the saucepan 7. While abutting against the saucepan 7, the positioning component 22 can also pass the placed rivet 6 through the hole position to be riveted on the saucepan 7, and abut against the rivet 6, and jointly squeeze the rivet 6 with the riveting mechanism 3, so that the rivet 6 is deformed, so that the pot body and the pot ear or the pot handle are riveted together. Compared with the prior art, the setting of the positioning component 22 can rivet multiple parts to be riveted of the workpiece to be riveted at the same time, and can also abut against the rivet 6 while conveying the rivet 6, effectively improving the riveting efficiency, and improving the integration and miniaturization of the equipment.

[0056] In this embodiment, as Figure 1 and Figure 6 shown, the first driving member 32 is installed on the mounting surface 11, and a riveting head 31 is provided at the output end of the first driving member 32, so that the riveting head 31 is arranged facing the positioning component 22, and the saucepan 7 is located between the riveting head 31 and the positioning component 22. The positioning component 22 pushes the rivet 6 out from the hole position to be riveted and abuts against the riveting head 31. It can be understood that when the first driving member 32 drives the riveting head 31 to move towards the positioning component 22, the riveting head 31 presses against the rivet 6, and the positioning component 22 pushes against the rivet 6 in the opposite direction, and the combined action deforms the rivet 6 to rivet the pot body and the pot ear or the pot handle tightly together.

[0057] The riveting device 100 of this technical solution forms an installation surface 11 through the machine body 1, which is used to install and place the positioning mechanism 2, the riveting mechanism 3 and the feeding device 4. Among them, a rotatable rotating platform 111 is provided on the installation surface 11, and the positioning mechanism 2 is arranged on the rotating platform 111. The positioning mechanism 2 includes a positioning block 21 arranged at the center of the rotating platform 111 and a plurality of positioning components 22 arranged on the periphery of the positioning block 21. The plurality of positioning components 22 can abut against the inner wall of the soup pot 7 to keep it fixed, and the positioning block 21 can also be replaced to adapt to soup pots 7 with different diameters. The riveting mechanism 3 is arranged adjacent to the positioning mechanism 2. While the positioning component 22 abuts against the inner wall of the soup pot 7, it also passes the rivet 6 placed inside it through the soup pot 7. The riveting mechanism 3 rivets the rivet 6 passing through the soup pot 7 on the outer wall of the soup pot 7 to deform the rivet 6 to rivet the soup pot 7. Specifically, the riveting mechanism 3 includes a riveting head 31 and a first driving member 32. The first driving member 32 is used to drive the riveting head 31 to move towards the positioning component 22. The riveting head 31 and the positioning component 22 abut against the rivet 6 on both sides of the soup pot 7 to deform the rivet 6 to achieve riveting. The riveting device 100 is also provided with a feeding device 4. The feeding device 4 is slidably arranged on the installation surface 11 and is arranged adjacent to the positioning component 22 for feeding the rivet 6 to the positioning component 22. Through this riveting device 100, automatic riveting of the rivet 6 and automatic riveting of products of the soup pot 7 type are realized, improving the production efficiency and the degree of automation of riveting, and effectively saving labor costs.

[0058] In an embodiment, the machine body 1 forms a cavity 12. The rotating platform 111 is provided with a plurality of avoidance grooves 1111 communicating with the cavity 12. One end of the positioning component 22 penetrates through the avoidance groove 1111 and extends into the cavity 12. The avoidance grooves 1111 extend linearly from the positioning block 21 to the edge of the rotating platform 111 so that the positioning component 22 can move in the avoidance groove 1111.

[0059] In this embodiment, as Figures 1 to 3As shown in the figure, a plurality of through avoidance grooves 1111 are formed in the rotating platform 111, and the avoidance grooves 1111 are all communicated with the cavity 12. One end of the positioning assembly 22 installed on the periphery of the positioning block 21 can be placed in the avoidance hole and can extend into the cavity 12. It can be understood that since the positioning assembly 22 is relatively large in size, when it is installed on the periphery of the positioning block 21, an activity space needs to be reserved for it. At the same time, in the prior art, a set of riveting equipment 100 is usually only applicable to one mainstream product, so that the existing riveting equipment 100 has low versatility and applicability. When there is a new product, the structure of the existing riveting equipment 100 usually needs to be greatly adjusted to adapt to the new product. In this application, in order to adapt to soup pots 7 with different inner diameters, the size and shape of the positioning block 21 can also be replaced. When the inner diameter of the soup pot 7 is larger, the size of the positioning block 21 is also larger. That is, for soup pots 7 with different diameters, only the positioning block 21 needs to be replaced to achieve the adaptation to different products. At this time, the position of the positioning assembly 22 also changes compared with when it is installed on the smaller positioning block 21. The setting of the avoidance groove 1111 provides an activity space for this position change of the positioning assembly 22. Through the setting of the positioning block 21 and the avoidance groove 1111, it is more convenient to replace different models of products, and the versatility and adaptability of the riveting equipment 100 are improved.

[0060] In an embodiment, a guiding groove 1112 is formed on the side of the rotating platform 111 facing away from the mounting surface 11. The guiding groove 1112 linearly penetrates through the center of the rotating platform 111, so that the positioning assembly 22 is symmetrically arranged with respect to the guiding groove 1112. The positioning mechanism 2 further includes a positioning baffle 23. One end of the positioning baffle 23 is slidably arranged in the guiding groove 1112, and the other end abuts against the outer wall of the soup pot 7 to cooperate with the positioning assembly 22 to fix the soup pot 7.

[0061] In this embodiment, as Figures 2 to 3 shown, a guiding groove 1112 is formed on the side of the rotating platform 111 facing away from the side abutting against the mounting surface 11. The guiding groove 1112 is linearly arranged and penetrates through the center of the rotating platform 111, and the positioning assembly 22 is symmetrically arranged left and right with respect to the guiding groove 1112. One end of the positioning baffle 23 is slidably arranged in the guiding groove 1112, and the other end is curved and abuts against the outer wall of the soup pot 7. It can be understood that the soup pot 7 is arranged between the positioning baffle 23 and the positioning assembly 22, so that the positioning baffle 23 and the positioning assembly 22 jointly position and fix the soup pot 7 to prevent the soup pot 7 from shaking or tilting during riveting. At the same time, in order to adapt to soup pots 7 with different diameters, the position of the positioning baffle 23 can also change along with the guiding groove 1112, which improves the stability of the soup pot 7 and also enhances the versatility and adaptability of the positioning mechanism 2.

[0062] In one embodiment, the positioning assembly 22 includes a housing 221 and a second driving member 222. The housing 221 is mounted on the periphery of the positioning block 21. A limiting hole 2211 is formed at one end of the housing 221 away from the positioning block 21. The limiting hole 2211 is used to place the rivets 6 conveyed by the feeding device 4. A placing cavity 2212 is formed in the housing 221. The limiting hole 2211 communicates with the placing cavity 2212. The second driving member 222 is disposed in the placing cavity 2212. A top column 2221 is provided at the output end of the second driving member 222. The direction of the axis of the top column 2221 coincides with the direction of the axis of the limiting hole 2211. The second driving member 222 can drive the top column 2221 into the limiting hole 2211 and push the rivet 6 out of the limiting hole 2211 to push the rivet 6 through the soup pot 7.

[0063] In this embodiment, as Figure 4 and Figure 5 shown, the positioning assembly 22 is mounted on the periphery of the positioning block 21 through the housing 221. A cavity 12 is formed inside the housing 221. A limiting hole 2211 communicating with the cavity 12 is formed on the surface of the housing 221 on the side away from the positioning block 21. The second driving member 222 is mounted in the cavity 12. The second driving member 222 is provided with a top column 2221 whose axis direction coincides with the axis direction of the limiting hole 2211. It can be understood that the feeding device 4 conveys the rivets 6 into the limiting hole 2211 of the positioning assembly 22. The rivets 6 are placed in the limiting hole 2211 in a limited manner. When the position of the soup pot 7 and the positioning assembly 22 is determined, the second driving member 222 in the positioning assembly 22 drives the top column 2221 to push the rivet 6 to move. The rivet 6 transfers from the limiting hole 2211 to the riveting hole position of the soup pot 7, and the rivet 6 passes through the soup pot 7. Compared with the prior art, while the positioning assembly 22 pushes the rivet 6 to move through the second driving member 222, it can also abut against the rivet 6 when the riveting mechanism 3 rivets the rivet 6, expanding the usage scenario of the positioning assembly 22 and effectively improving the riveting efficiency.

[0064] In one embodiment, two rotating shafts are provided at one end of the housing 221 away from the positioning block 21. The two rotating shafts are placed in the vertical direction. A limiting plate 2213 is provided on each rotating shaft. The two limiting plates 2213 are respectively disposed on the horizontal two sides of the limiting hole 2211, and each limiting plate 2213 is elastically connected to the housing 221; a semi-circular groove is provided at one end of each limiting plate 2213 adjacent to the limiting hole 2211. The two semi-circular grooves enclose a through groove. The through groove communicates with the limiting hole 2211, so that the rivet 6 can pass through the through groove and enter the limiting hole 2211, and one end of the rivet 6 is placed in the through groove.

[0065] In this embodiment, as Figure 4 and Figure 5As shown, on the surface of the housing 221 on the side where the limiting holes 2211 are provided, there are two rotatable limiting plates 2213. The limiting plates 2213 rotate through the rotating shafts provided on both sides of the limiting holes 2211 in the vertical direction. One end of the limiting plate 2213 is arranged adjacent to the orifice of the limiting hole 2211, and the other end is elastically connected to the housing 221. Each end of the limiting plate 2213 adjacent to the orifice of the limiting hole 2211 is provided with a semi-circular groove, and the two semi-circular grooves form a through groove. The axial direction of the through groove coincides with the axial direction of the limiting hole 2211, and the through groove communicates with the limiting hole 2211. The diameter of the through groove is smaller than the diameter of the limiting hole 2211.

[0066] It can be understood that the rivet 6 has a head end and a stud end. When the rivet 6 passes through the limiting plates 2213 provided on both sides of the limiting hole 2211 from the head end, the head pushes the limiting plates 2213 to rotate towards the side of the limiting hole 2211, and the head enters the limiting hole 2211. When the head completely enters the limiting hole 2211, the two limiting plates 2213 rebound towards the direction away from the limiting hole 2211 under the action of the elastic force elastically connected to the housing 221, so that the stud is exactly in the through groove. Since the diameter of the through groove is smaller than the diameter of the limiting hole 2211 and the diameter of the through groove is slightly larger than the diameter of the stud, the stud is placed in the through groove in a limited manner, and the stud of the rivet 6 is in a horizontal state. When the second driving member 222 pushes the tubular rivet 6 out of the limiting hole 2211, the head can also push the limiting plate 2213 to rotate towards the direction away from the limiting hole 2211, so that the rivet 6 can be completely withdrawn from the positioning assembly 22. The setting of the limiting plate 2213 can not only realize the two-way entry and exit of the rivet 6 through the elastic connection between the limiting plate 2213 and the housing 221, but also realize the horizontal limited placement of the rivet 6 through the through groove, ensuring that the rivet 6 always moves along its axis direction when entering and exiting, improving the movement accuracy and avoiding deflection.

[0067] In one embodiment, the riveting head 31 gradually decreases in cross-section from the end connected to the first driving member 32 to the end facing the positioning assembly 22. The end of the riveting head 31 facing the positioning assembly 22 is provided with a riveting surface 311, and a positioning circular groove 3111 is provided on the riveting surface 311 to position and shape the rivet 6 during riveting.

[0068] It can be understood that as Figure 6 and Figure 7As shown, the outer shape of the riveting head 31 gradually decreases in cross-section from the end connected to the first driving member 32 to the end facing the positioning assembly 22, and it can be a pyramid shape or a cone shape. With such a setting, on the one hand, it can avoid the pot ears or pot handles around the hole position to be riveted, preventing movement interference; on the other hand, the gradually decreasing cross-section setting can also enable the riveting head 31 to have good centering performance, accurately aligning with the rivet 6 to be riveted and avoiding deflection. One end of the riveting head 31 facing the positioning assembly 22 is provided with a riveting surface 311, and a positioning circular groove 3111 is arranged on the riveting surface 311. The positioning circular groove 3111 can position the rivet 6 during riveting, preventing the rivet 6 from slipping off. At the same time, the concave circular arc-shaped positioning circular groove 3111 can also shape the rivet post of the rivet 6 during riveting, making it form a uniformly round and smooth arc shape, improving the aesthetics of the riveting.

[0069] In one embodiment, there are two riveting mechanisms 3, and the two riveting mechanisms 3 are relatively arranged on both sides of the rotating platform 111. The two first driving members 32 drive the riveting heads 31 to move towards the positioning assembly 22, and the straight lines where the movement directions are located both pass through the center of the rotating platform 111, so as to rivet two positions of the soup pot 7 that are symmetric about the center of the rotating platform 111.

[0070] It can be understood that, as Figure 1 and Figure 6 shown, there are two riveting mechanisms 3 provided on both sides of the rotating platform 111, and the riveting heads of the two riveting mechanisms 3 are both oriented towards the rotating platform 111. The movement directions of the two first driving members 32 are on the same straight line and pass through the center of the rotating platform 111. The two riveting mechanisms 3 can operate simultaneously and move towards the positioning assembly 22 arranged on the rotating platform 111. There are at least two positioning assemblies 22 arranged on the positioning block 21 and are respectively arranged opposite to one riveting structure, so that when the riveting mechanism 3 cooperates with the positioning assembly 22 for riveting, the two riveting mechanisms 3, the two positioning assemblies 22, and the positioning block 21 are on the same straight line, avoiding poor riveting effects or even damage to the workpiece to be riveted due to deflection.

[0071] In one embodiment, a slide rail 112 is further arranged on the mounting surface 11. The feeding device 4 is provided with a sliding table 41 that cooperates with the slide rail 112, so that the feeding device 4 can slide along the slide rail 112. The feeding device 4 includes a third driving member 42 and a feeding component 43. The third driving member 42 is installed on the sliding table 41, and the output end of the third driving member 42 faces the positioning assembly 22. The feeding component 43 is installed at the output end of the third driving member 42, so that the third driving member 42 drives the feeding component 43 to approach or move away from the positioning assembly 22.

[0072] In this embodiment, as Figure 1 and Figure 8As shown in the figure, a slide rail 112 is provided on the mounting surface 11 along the moving direction of the first driving member 32 in the riveting mechanism 3. The feeding device 4 is provided with a sliding table 41 that cooperates with the slide rail 112, so that the feeding device 4 can slide along the slide rail 112. The feeding device 4 includes a third driving member 42 provided on the sliding table 41 and a feeding component 43 provided at the output end of the third driving member 42. It can be understood that on the one hand, the third driving member 42 can slide along the slide rail 112 through the sliding table 41, and on the other hand, it can drive the feeding component 43 to move in a direction perpendicular to the slide rail 112, so that the feeding component 43 can approach or move away from the positioning component 22. When the feeding component 43 carrying the rivets 6 moves towards the positioning component 22 under the drive of the third driving member 42 and pushes the rivets 6 in the feeding component 43 into the positioning component 22, the transfer and transmission of the rivets 6 are realized. Compared with manually loading the rivets 6 in the prior art, this device can automatically load the rivets 6, improve the automation degree of the riveting equipment 100, and effectively save labor costs.

[0073] In an embodiment, the feeding component 43 includes a support frame 431, a fourth driving member 432 and a turning plate 433. The support frame 431 is installed at the output end of the third driving member 42. The fourth driving member 432 is installed on the support frame 431. A plurality of pushing columns 4321 are provided at one end of the output end of the fourth driving member 432 facing the positioning component 22. The turning plate 433 is rotatably provided on the support frame 431. The turning plate 433 is provided with a plurality of placement holes 4331 corresponding to the pushing columns 4321 for placing the rivets 6. The turning plate 433 has a first position for loading the rivets 6 and a second position for delivering the rivets 6. Wherein, when the turning plate 433 is in the second position, the fourth driving member 432 pushes the pushing columns 4321 to move, and the pushing columns 4321 push the rivets 6 provided in the placement holes 4331 towards the positioning component 22 to deliver the rivets 6 into the positioning component 22.

[0074] In this embodiment, as Figure 8 shown, the support frame 431 is installed at the output end of the third driving member 42, and the support frame 431 is used to install and fix the fourth driving member 432 and the turning plate 433. The turning plate 433 is rotatably provided at one end of the support frame 431 facing the positioning component 22, and a plurality of placement holes 4331 are provided on the turning plate 433 for placing the rivets 6; the turning plate 433 has a first position for loading the rivets 6 and a second position for delivering the rivets 6. A plurality of pushing columns 4321 corresponding to the plurality of placement holes 4331 are provided on the output end of the fourth driving member 432.

[0075] It can be understood that when the turning plate 433 is in the first position, the maximum cross-section direction of the turning plate 433 is parallel to the mounting surface 11, and the axial direction of the placement hole 4331 is perpendicular to the mounting surface 11. At this time, the rivet 6 can be inserted into the placement hole 4331; the turning plate 433 can be driven to turn through the driving mechanism, so that the maximum cross-section direction of the turning plate 433 is in the second position perpendicular to the mounting surface 11. At this time, the rivet 6 placed in the placement hole 4331 is pushed out of the placement hole 4331 and into the positioning assembly 22 by the fourth driving member 432 provided with the pushing column 4321, realizing the loading of the rivet 6 into the positioning assembly 22. Compared with the manual loading of the rivet 6 in the prior art, the structure of the feeding assembly 43 can realize the automatic loading of the rivet 6. Through the setting of the first position and the second position of the turning plate 433, the feeding assembly 43 can freely switch the working state, improving the flexibility and automation degree of the riveting device 100.

[0076] In another embodiment, an elastic latch is provided in the turning plate 433. The elastic latch is disposed adjacent to the placement hole 4331, one end of which is elastically connected to the turning plate 433, and the other end is clamped to the rivet 6. At the same time, when the fourth driving member 432 pushes the rivet 6 disposed in the placement hole 4331 through the pushing column 4321, the elastic latch is opened under the thrust of the rivet 6 to realize the two-way entry and exit of the rivet 6. After the rivet 6 is completely pushed out of the placement hole 4331, the elastic latch returns to its original position under the action of the elastic force. The elastic latch realizes that the rivet 6 can be accurately positioned and fixed to the corresponding position during the entry and exit processes, and at the same time realizes the two-way entry and exit of the rivet 6, improving its automation degree.

[0077] In one embodiment, the riveting device 100 further includes a feeding device 5. The feeding device 5 is disposed on the mounting surface 11 and adjacent to the slide rail 112. The feeding device 5 includes a screening plate 51, a slideway 52 and a fifth driving member 53. The screening plate 51 is used for placing the rivets 6. One end of the slideway 52 is connected to the screening plate 51 for transmitting the rivets 6. The fifth driving member 53 is mounted on the mounting surface 11, and the end of the slideway 52 away from the screening plate 51 is disposed directly above the output end of the fifth driving member 53, so that the rivets 6 can be placed on the output end of the fifth driving member 53 through the slideway 52; wherein, when the turning plate 433 is in the first position for loading the rivets 6, the fifth driving member 53 pushes the rivets 6 into the placement hole 4331.

[0078] In this embodiment, as Figure 1As shown in the figure, the feeding device 5 is arranged on the mounting surface 11 and is disposed adjacent to one end of the slide rail 112, and the other end of the slide rail 112 is adjacent to the positioning component 22. The screening plate 51 is used for placing and screening the rivets 6. The rivets 6 derived from the screening plate 51 are placed directly above the fifth driving member 53 through the slideway 52 and are mounted on the output end of the fifth driving member 53. At this time, the feeding component 43 can drive the turning plate 433 to reach the vicinity of the feeding device 5 through the slide rail 112. The turning plate 433 is in the first position, and the placement hole 4331 of the turning plate 433 is directly opposite to the rivet 6 in the fifth driving member 53. The output end of the fifth driving member 53 pushes the rivet 6 into the placement hole 4331 of the turning plate 433 and fixes the rivet 6 in the placement hole 4331 through the elastic locking structure, thus realizing the loading of the rivet 6.

[0079] It can be understood that the screening plate 51 can achieve the sorting of the nail heads and nail columns of the rivets 6 through its own vibration or by using the principle that the rivets 6 are heavier at the head and lighter at the foot, so that when the rivets 6 are derived from the screening plate 51, the nail heads are all facing upward or the nail columns are all facing upward. In another embodiment, the slideway 52 includes a first slideway 52 and a second slideway 52. One end of the first slideway 52 is connected to the outlet of the screening plate 51, and the other end is connected to the second slideway 52. The first slideway 52 and the second slideway 52 are arranged at an angle, and a sensor is provided directly above the interface position of the first slideway 52 and the second slideway 52 for detecting whether the rivets 6 are in place, so as to avoid the fifth driving member 53 running empty. The end of the second slideway 52 far from the connection with the first slideway 52 is arranged directly above the fifth driving member 53. When it is detected by the sensor whether the rivets 6 are in place, if they are in place, a driving member is used to push the rivets 6 above the fifth driving member 53 and make them fall onto the output end of the fifth driving member 53. Then, the output end of the fifth driving member 53 pushes the rivets 6 into the placement hole 4331 of the turning plate 433. The cooperation between the feeding device 5 and the feeding component 43 can realize the automatic sorting and screening of the rivets 6, the detection of the rivets 6 in place, the automatic loading of the rivets 6, and the automatic delivery of the rivets 6, effectively improving the automation degree of the riveting device 100. At the same time, the feeding device 5 and the feeding component 43 can also be applied to other fields and devices, having a wide range of application scenarios.
