[0028] refer to Figures 1 to 5 The present application embodiment provides an alternating feeding device for riveting, comprising a riveting press 10 and an alternating feeding mechanism 20, wherein the riveting press 10 is provided with a riveting head 11 and a carrier 12, and the carrier 12 is located directly below the riveting head 11; wherein the alternating feeding mechanism 20 comprises a mounting plate 21, a transmission belt 22, a first feeding platform 23 and a second feeding platform 24, wherein the mounting plate 21 is horizontally arranged on the top of the carrier 12, and support rails 211 are symmetrically arranged on both sides in the length direction, and the support rails 211 extend along the length direction of the mounting plate 21, wherein the transmission belt 22 is arranged on the top of the carrier 12, and the support rails 211 extend along the length direction of the mounting plate 21, and ... 22 and the mounting plate 21 are kept parallel and are arranged between the two support rails 211 in a closed-loop rotating manner. In addition, the sides of the transmission belt 22 close to the support rail 211 are defined as the first side 221 and the second side 222, respectively, wherein the first loading platform 23 is fixedly connected to the first side 221 of the transmission belt 22, wherein the second loading platform 24 includes a second loading carrier plate 241 and second support platforms 242 symmetrically arranged on both sides of the first loading platform 23 along the length direction of the mounting plate 21, wherein the second support platform 242 close to the second side 222 is fixedly connected to the first side 221 of the transmission belt 22, The second side edge 222 is provided, and the second loading carrier plate 241 and the mounting plate 21 are kept parallel, and are connected to the second support platforms 242 on both sides by guide columns 243 extending in the vertical direction. In addition, cam followers 244 matching with the support guide rails 211 on both sides are respectively provided on both sides of the second loading carrier plate 241, and the mounting plate 21 is provided with guide rails 25 matching with the first loading platform 23 and the second loading platform 24, so that when the transmission belt 22 rotates, the first loading platform 23 and the second loading platform 24 can be alternately oriented and moved to the bottom of the riveting head 11, and When the positions of the first loading platform 23 and the second loading platform 24 overlap, based on the cooperation relationship between the cam follower 244 and the supporting guide rails 211 on both sides, the second loading plate 241 can pass over the first loading platform 23 from above the first loading platform 23, so that the first loading platform 23 and the second loading platform 24 can be driven to move reciprocatingly and directional through the reciprocating rotation of the transmission belt 22, and then alternately move to the bottom of the riveting head 11 to complete the riveting operation, wherein the other side of the mounting plate 21 away from the riveting head 11 is the loading side, and only manual or automatic material discharge and material collection are required, without delaying the riveting operation.

[0029] In detail, taking the first loading platform 23 with the product located directly below the riveting head 11 as an example, at this time, the second loading platform 24 is located at the other end of the mounting plate 21 away from the riveting head 11, which is called a waiting position and can be used for manual or automatic loading;

[0030] After the product on the first loading platform 23 is riveted, the transmission belt 22 rotates to make the first loading platform 23 move to the other end, and the second loading platform 24 moves toward the riveting head 11. When it moves to the overlapping position, the second loading platform 241 is supported to a certain height based on the cooperation relationship between the cam follower 244 and the support guide rail 211, and then the first loading platform 23 can pass over the first loading platform 23 from above, and then reset to maintain the original height direction and move to the bottom of the riveting head 11. At this time, the first loading platform 23 moves to the waiting position, and then the product on the second loading platform 241 can be directly riveted by the riveting head 11. At the same time, the riveted finished product on the first loading platform 23 can be manually or automatically removed and replaced with the product to be riveted, and the riveting of the product on the second loading platform 241 will not be delayed. It can ensure that the riveting head 11 continues to perform the riveting operation, avoiding the process of having to take out the finished product first and then put in the new product, shortening the waiting time of the riveting head 11, and improving work efficiency.

[0031] In addition, it is also necessary to note that in the process of the second loading carrier 241 moving up and over the first loading platform 23, the second loading carrier 241 always remains connected through the guide column 243 and the second support platform 242, that is, the guide column 243 has a sufficient height to guide and limit the second loading carrier 241.

[0032] In one embodiment, a positioning plate 212 is further provided on the top of the mounting plate 21. The positioning plate 212 is fixedly provided in a suspended manner directly below the riveting head 11, and in the height direction, the positioning plate 212 is located above the first loading platform 23 and the second loading platform 24, so as to position and regularize the products on the first loading platform 23 and the second loading carrier plate 24 when the first loading platform 23 and the second loading platform 24 are in place, thereby ensuring the riveting quality.

[0033] Further preferably, the positioning plate 212 is connected to the mounting plate 21 through a first cylinder 213 and a second cylinder 214, wherein the first cylinder 213 is vertically arranged on the top of the mounting plate 21, wherein the second cylinder 214 is horizontally connected to the telescopic end of the top of the first cylinder 213, and at the same time, the positioning plate 212 is horizontally connected to the telescopic end of the second cylinder 214, so that the height position and horizontal placement of the positioning plate 21 can be flexibly moved through the cooperation of the first cylinder 213 and the second cylinder 214, so that the positioning plate 21 is suitable for positioning different products and has a wide range of applications.

[0034] In one embodiment, the guide rail 25 includes a first guide rail 251 and a second guide rail 252 extending in the same direction along the length direction of the mounting plate 21 and close to the inner side, and a third guide rail 253 and a fourth guide rail 254 extending in the same direction and located on the outer sides of the first guide rail 251 and the second guide rail 252, wherein the first loading platform 23 is slidably matched with the first guide rail 251 and the second guide rail 252, and the two second support platforms 242 are slidably matched with the third guide rail 253 and the fourth guide rail 254 respectively.

[0035] Further preferably, the two support rails 211 are respectively located on the outside of the third guide rail 253 and the fourth guide rail 254, and the support rail 211 is a support plate, and the top of the support rail 211 is a triangular structure, including a horizontal portion and inclined portions symmetrically arranged on both sides of the horizontal portion, wherein there is an arc-shaped transition between the inclined portion and the horizontal portion, and in the initial state, the cam follower 244 is opposite to the inclined portion, so that the cam follower 244 can smoothly move to the horizontal portion through the inclined portion, and finally reset in the height direction through the inclined portion, thereby ensuring that the second loading plate 241 can smoothly cross the first loading platform 23, wherein the initial state refers to the state when the positions of the first loading platform 23 and the second loading platform 24 do not overlap.

[0036] Further preferably, the support rail 211 is an annular support plate, so that the weight of the support rail 211 can be reduced while ensuring the support strength, making the alternating feeding device lightweight and more convenient to use.

[0037] In one embodiment, the first loading platform 23 includes a first support platform 232 that slides with the first guide rail 251 and the second guide rail 252 respectively, and a first loading carrier plate 231 horizontally elastically connected to the top of the two first support platforms 232. At the same time, the first loading carrier plate 231 and the first support platform 232 maintain a clearance fit, so that the riveting pressure can be avoided from being directly transmitted to the first support platform 232 when the riveting head 11 is performing the riveting operation, thereby ensuring that the first support platform 232 will not be easily deformed by the riveting pressure, thereby increasing the service life of the first support platform 232 and reducing the cost of use.

[0038] More specifically, a spring 2321 is installed in the first support platform 232, and the first loading plate 231 is locked in the first support platform 232 by the shoulder screw 2322. At the same time, the shoulder screw 2322 and the first loading plate 231 are clearance-matched, and the first loading plate 231 is elastically connected to the first support platform 232 by the spring 2321 and maintains a gap, so that the first loading plate 231 has a certain small-pitch elastic activity space in the height direction.

[0039] In one embodiment, the second loading plate 241 and the second support platform 242 are elastically connected, and the second loading plate 241 and the second support platform 242 maintain a clearance fit. This method is similar to the connection method between the first loading plate 231 and the first support platform 232. The only difference is that the elastic stroke of the spring between the second loading plate 241 and the second support platform 242 is larger, so that the second loading plate 241 can be moved up to the top of the first loading platform 23. However, the role of the spring is also to ensure that the riveting head 11 will not be directly pressed down on the second support platform 242 during riveting, so as to prevent the second support platform 242 from being deformed by the riveting pressure.

[0040] In one embodiment, one end of the mounting plate 21 extends to the outside of the riveting press 10, and the bottom of the mounting plate 21 is vertically connected to a rotating motor 26 on the outside of the riveting press 10, wherein the rotating shaft of the rotating motor 26 extends to the top of the mounting plate 21, and a driving wheel 261 is coaxially sleeved, and three driven wheels 262 that cooperate with the driving wheel 261 are also installed on the top of the mounting plate 21, so that a square structure suitable for transmitting and supporting the transmission belt 22 is formed through the driving wheel 261 and the driven wheels 262. In addition, a tensioning wheel 263 for tensioning the transmission belt 22 is also provided on the top of the mounting plate 21, which can ensure the transmission accuracy of the transmission belt 22.

[0041] It should be noted that the terms "first, second" in the present application are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0042] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
