The frame 110 has a material taking station and a welding station, the feeding mechanism 120 is installed on the frame 110 by screwing, welding, etc., the feeding mechanism 120 is used for feeding the rivet to the material taking station, and the rivet welding device 100 is used for welding the rivet to the ferrule.

A transport mechanism 140 is spaced from the frame 110, and the transport mechanism 140 is used to transport the ferrule to a welding station in preparation for welding rivets on the ferrule. In this embodiment, the conveying mechanism 140 is fixed on the work bench, for example, the conveying mechanism 140 is fixed on the floor of the operation area, and the conveying mechanism 140 is spaced apart from the frame 110, so that when rivets are to be welded on the ferrules, the corresponding ferrules can be conveyed to the welding station by the conveying mechanism 140.

The welding mechanism 130 is movable between a take-off station and a welding station, i.e., the welding mechanism 130 is movably coupled to the frame 110, and the welding mechanism 130 is movable between the take-off station and the welding station during movement of the welding mechanism 130. Specifically, the welding mechanism 130 includes a welding tongs body 131, a clamping component 132 and a welding component 133, the clamping component 132 and the welding component 133 are disposed on the welding tongs body 131 through a bolt joint and welding, the welding tongs body 131 is movably disposed on the frame 110, when the welding tongs body 131 moves on the frame 110, the welding tongs body 131 drives the clamping component 132 and the welding component 133 to move between the material taking station and the welding station, the clamping component 132 is used for grabbing and releasing the rivet, and the welding component 133 is used for welding the rivet on the hoop. In this embodiment, when the soldering turret body 131 drives the clamping assembly 132 to move to the material taking station, the clamping assembly 132 performs a clamping operation on the rivet at the material taking station; and when the welding tongs body 131 drives the clamping component 132 and the welding component 133 to move to the welding station, the welding component 133 performs welding operation on the rivet at the welding station, and after the welding operation of the rivet is completed, the clamping component 132 can release the rivet, so that the welding mechanism 130 is convenient to reset, and preparation is made for the next welding operation of the rivet.

In the rivet welding apparatus 100, the feeding mechanism 120 is mounted on the frame 110 and configured to feed the rivet to the material taking station, the welding mechanism 130 moves to the material taking station, the rivet located in the material taking station is grabbed by the clamping assembly 132, and after the rivet is grabbed by the clamping assembly 132, the welding tong body 131 drives the clamping assembly 132 and the welding assembly 133 to move to the welding station, and the rivet is welded on the hoop of the material supplied by the conveying mechanism 140 by the welding assembly 133, after the welding operation of the rivet on the hoop is completed, the clamping assembly 132 releases the rivet, and the welding mechanism 130 resets to prepare for the next welding operation of the rivet. According to the rivet welding device 100, the rivet welding operation on the hoop is automatically completed through the movement of the welding mechanism 130 between the material taking station and the welding station and the cooperation of the feeding mechanism 120 and the conveying mechanism 140, so that the rivet welding efficiency can be obviously improved, the labor intensity is reduced, the consistency of the welding position of the rivet on the hoop and a welding spot can be ensured, and the welding quality of the rivet on the hoop is greatly improved.

In order to grasp and release the rivet, in a preferred embodiment, as shown in fig. 1 and 3, the clamping assembly 132 includes a first driving member 1321, a first clamping plate 1322 and a second clamping plate 1323, wherein the first clamping plate 1322 and the second clamping plate 1323 are movably disposed on the soldering tweezers body 131, so as to fix the first clamping plate 1322 and the second clamping plate 1323, and facilitate adjusting a distance between the first clamping plate 1322 and the second clamping plate 1323. The first clamping plate 1322 is disposed opposite the second clamping plate 1323, i.e., the first clamping plate 1322 and the second clamping plate 1323 have a gap therebetween. The first driving member 1321 is fixed to the soldering turret body 131 by screwing, welding or the like, and an output end of the first driving member 1321 is in transmission connection with the first clamping plate 1322 and/or the second clamping plate 1323 to drive the first clamping plate 1322 and/or the second clamping plate 1323 to move, so as to adjust a distance between the first clamping plate 1322 and the second clamping plate 1323. When the clamping assembly 132 needs to capture the rivet at the material taking station, or the clamping assembly 132 needs to release the rivet at the welding station, the distance between the first clamping plate 1322 and the second clamping plate 1323 needs to be adjusted to be larger, at this time, the first clamping plate 1322 can be driven by the first driving member 1321 alone to move in the direction away from the second clamping plate 1323, or the second clamping plate 1323 can be driven by the first driving member 1321 alone to move in the direction away from the first clamping plate 1322, or the first driving member 1321 drives the first clamping plate 1322 and the second clamping plate 1323 simultaneously to move in the direction away from each other, so that the rivet can enter the gap between the first clamping plate 1322 and the second clamping plate 1323 and be captured by the first clamping plate 1322 and the second clamping plate 1323. When the rivet fastener needs to be conveyed from the material taking station to the welding station for welding, the distance between the first clamping plate 1322 and the second clamping plate 1323 needs to be adjusted to be smaller, at this time, the first driving member 1321 can be used for driving the first clamping plate 1322 to move towards the direction close to the second clamping plate 1323 alone, or the first driving member 1321 can be used for driving the second clamping plate 1323 to move towards the direction close to the first clamping plate 1322 alone, or the first driving member 1321 can be used for driving the first clamping plate 1322 and the second clamping plate 1323 to move towards the directions close to each other at the same time, so that the rivet fastener can be clamped and fixed by the first clamping plate 1322 and the second clamping plate 1323, and can be conveyed to the welding station from the material taking station by the clamping assembly 132.

Of course, the clamping assembly 132 is not limited to the combination of the first driving member 1321, the first clamping plate 1322 and the second clamping plate 1323, and the clamping assembly 132 may also be a combination of the first driving member 1321 and a mechanical clamping jaw, where the first driving member 1321 is in transmission connection with the mechanical clamping jaw, and the mechanical clamping jaw is driven to open and close by the first driving member 1321 to grasp and release the rivet. The specific structure of the mechanical clamping jaw is the same as that of the prior art, and is not described in detail herein.

In order to weld the rivet to the ferrule, in a preferred embodiment, as shown in fig. 1 and 2, the welding assembly 133 includes a transformer 1331 and a soldering turret 1332. The transformer 1331 is disposed on the soldering turret body 131 by screwing, welding, etc., and the soldering turret 1332 is also disposed on the soldering turret body 131 by screwing, welding, etc., so as to implement the mounting connection between the transformer 1331 and the soldering turret 1332, and the soldering turret 1332 is electrically connected to the transformer 1331. When the rivet needs to be welded on the hoop at a welding station, the voltage of the transformer 1331 is reduced, a larger welding current is provided, the welding pliers 1332 can conduct the welding current provided by the transformer 1331, the current density of a welding point at the end part of the welding pliers 1332 is ensured, the contact surface of the rivet and the hoop is subjected to heat melting, and therefore the rivet is welded on the hoop, and the welding operation of the rivet on the hoop is completed.

In order to weld rivets at different locations on the ferrule, in a preferred embodiment, the welding mechanism 130 further includes a rotating assembly 134, as shown in fig. 1 and 2. The rotating assembly 134 is disposed on the frame 110, and an output end of the rotating assembly 134 is in transmission connection with the soldering turret body 131. Because the number of the rivets welded on one hoop is not limited to one, more rivets are often welded on the same hoop to improve the reliability of the connection between the hoop and other structural members (such as cage bars and the like), the position of the welding surface of the rivet can be adjusted by the rotating component 134, so that the welding surface of the rivet is adjusted to a position opposite to the welding surface of the corresponding hoop, and the welding operation of the rivet and the hoop is completed. In this embodiment, when rivets need to be welded on all the four inner walls of the ferrule, the rotating assembly 134 can rotate the soldering turret body 131, the soldering turret body 131 drives the clamping assembly 132 and the welding assembly 133 to rotate, so that the welding surface of the rivet is opposite to the welding surface of the corresponding ferrule, and the welding surfaces of the rivets and the welding surface of the ferrule can be welded into a whole by the soldering turret 1332, so as to weld the rivets at different positions of the ferrule.

When the welding surface of the rivet needs to be adjusted, the second driving member 1341 outputs power to one of the gears in the gear set 1342 to drive the gear to rotate, the gear drives the other gear engaged with the gear to rotate, and the other gear outputs a rotating force to the soldering turret body 131 to adjust the position of the soldering turret body 131. Since the clamping assembly 132 and the welding assembly 133 are both fixed on the soldering turret body 131, in the rotating process of the soldering turret body 131, the clamping assembly 132 and the welding assembly 133 rotate in a follow-up manner to adjust the welding surface of the rivet to a position corresponding to the welding surface of the corresponding hoop, the welding operation of the rivet and the hoop is conveniently completed.

When the welding mechanism 130 needs to move along the X direction, the third driving element 1351 performs corresponding actions, the third driving element 1351 outputs power to the first moving plate 1353, and the first moving plate 1353 moves along the X direction on the first sliding rail 1352, so as to drive the welding mechanism 130 to move along the X direction on the frame 110.

Accordingly, the Y-direction driving assembly 136 includes a fourth driving member 1361, a second slide rail 1362 and a second moving plate 1363.

The material storage rod 123 extends towards the direction perpendicular to the fixing surface of the material storage rod 123, in the embodiment, the whole shape of the material storage rod 123 is rod-shaped, and the material storage rod 123 is vertically fixed on the feeding frame 121. The material pushing assembly 122 is provided with a material clamping groove 1223, the opening of the material clamping groove 1223 faces the material storage rod 123, and due to the fact that the material storage rod 123 is vertically fixed on the feeding frame 121, under the action of gravity or the action of external forces such as elastic force, the rivet button stored in the material storage cavity 1231 can freely fall into the material clamping groove 1223, and the material clamping groove 1223 can bear the rivet button falling from the material storage rod 123. The material pushing assembly 122 is fixed on the feeding frame 121 through screwing, welding and other modes, the material pushing assembly 122 is used for pushing the rivet held on the material clamping groove 1223 to the material taking station so as to complete the feeding operation of the rivet, and the rivet can be conveniently grabbed by the welding mechanism 130 at the material taking station.

In order to achieve intermittent feeding of the rivet, in particular, as shown in fig. 1, 6 and 7, the feeding mechanism 120 further includes a striker plate 124. The striker plate 124 and the feeding frame 121 are arranged at an interval, a material passing hole 125 is formed between the striker plate 124 and the feeding frame 121, and the material passing hole 125 is positioned between the material storage rod 123 and the material taking station. Because a large number of rivets are stored in the material storage rod 123, under the action of gravity or external force such as elastic force, the rivets can fall off in a centralized manner, due to the existence of the material passing hole 125, the material blocking plate 124 can block other rivets which do not need to be pushed to the material taking station, and the rivets which need to be moved to the material taking station are allowed to be sent to the material taking station through the material passing hole 125, that is, only one rivet can be pushed to pass through the material passing hole 125 by a single movement of the material pushing assembly 122 and then sent to the material taking station, so that the rivet can be conveniently grabbed at the material taking station by the welding mechanism 130, and the intermittent feeding of the rivets is realized.

As shown in fig. 1, 6 and 7, the pushing assembly 122 includes a sixth driving element 1221 and a pushing rod 1222. The sixth driving member 1221 is directly or indirectly arranged on the feeding frame 121 through screwing, welding and other modes, and the output end of the sixth driving member 1221 is in transmission connection with the push rod 1222. In this embodiment, the push rod 1222 is rod-shaped as a whole, the push rod 1222 is horizontally fixed on the feeding frame 121, and the material clamping groove 1223 is opened on the push rod 1222. When the sixth driving element 1221 moves, the driving rod 1222 can be driven to move in the horizontal direction, so as to push the rivet received in the material clamping groove 1223 to the material taking station, so as to prepare for the rivet grabbing operation of the welding mechanism 130. The sixth driving element 1221 may be one of a pneumatic element or an electric element. Taking the sixth driving element 1221 as a pneumatic element, for example, if the sixth driving element 1221 is an air cylinder, the air cylinder is fixed on the feeding frame 121 by screwing, welding, etc., the push rod 1222 is connected to the output shaft of the air cylinder, and when the air cylinder acts, the air cylinder can drive the push rod 1222 to move in the horizontal direction. If the sixth driving member 1221 is a motor-driven element, the user can specifically set the element type.

In order to further facilitate the grabbing operation of the rivet by the welding mechanism 130, specifically, as shown in fig. 1, fig. 6 and fig. 7, the feeding mechanism 120 further includes a turning member 126, and the turning member 126 is rotatably connected to the feeding frame 121. In this embodiment, the cross section of the push rod 1222 in the direction perpendicular to the extending direction thereof is triangular, when the push rod 1222 pushes the rivet to the material taking station, the rivet can obliquely overlap the material clamping groove 1223 formed on the push rod 1222, and when the push rod 1222 moves along the X direction, the rivet moves to the material taking station along with the push rod 1222, so that the welding mechanism 130 can perform grabbing operation on the rivet. The turning part 126 is provided with a material taking part 1261, when the push rod 1222 pushes the rivet to the material taking station, the material taking part 1261 can absorb and grab the rivet, and the rivet is adjusted to the position easily grabbed by the welding mechanism 130 by adjusting the angle of the rivet through the rotation of the turning part 126 on the feeding frame 121, so that the grabbing operation of the rivet by the welding mechanism 130 is further facilitated.

It should be noted that the cross section of the push rod 1222 in the direction perpendicular to the extending direction thereof is not limited to the triangle provided above, and may also be a quadrilateral or other polygons, and the invention is not limited to the specific shape of the cross section of the push rod 1222, and may be set according to the specific process. In this embodiment, the end of the flip-flop 126 is provided with a magnetic element to form the material taking part 1261, and since the rivet has magnetism, the rivet can be quickly attracted and grabbed under the magnetic action of the magnetic element, so that the welding efficiency of the rivet is improved. Of course, in other embodiments, a buckle, a clamping plate, or other elements capable of grabbing a rivet may be disposed at the end of the flip-over member 126, and the invention is not limited to how the material taking portion 1261 is disposed on the flip-over member 126.
