Referring to fig. 1, an embodiment of the present application provides a welding apparatus including a rack 1, a welding mechanism 2, a first feeding mechanism 3, and a second feeding mechanism 4; the welding mechanism 2 comprises a plurality of first welding seats 20 and a plurality of second welding seats 21, the plurality of first welding seats 20 are longitudinally arranged at the upper end of the rack 1 at intervals, the plurality of second welding seats 21 can be movably arranged on the rack 1 up and down, and the plurality of second welding seats 21 are correspondingly arranged right above the plurality of first welding seats 20; the first feeding mechanism 3 is used for conveying the plurality of transverse ribs 101 to the upper ends of the plurality of first welding seats 20 in a one-to-one correspondence manner; the second feeding mechanism 4 is used for alternately conveying the single longitudinal ribs 102 to the upper ends of the plurality of first welding seats 20 at intervals; when the second welding seats 21 are moved downward, the longitudinal ribs 102 are pressed and welded to the transverse ribs 101. After accomplishing a welding operation, move one section displacement toward the direction of first welding seat 20 through a plurality of horizontal muscle 101 of 3 drive of first feed mechanism promptly, rethread second feed mechanism 4 carries a vertical muscle 102 to the upper end of first welding seat 20 to welding operation next time repeats this operation, can form network structure's steel skeleton with a plurality of horizontal muscle 101 and a plurality of vertical muscle 102 welding.

Referring to fig. 2-5, in some embodiments of the present application, the first feeding mechanism 3 includes a fixing plate 31, a push plate 32, and a plurality of stoppers 33; the fixing plate 31 is arranged on the rack 1, a plurality of positioning slots 311 (shown in fig. 3) for accommodating the single transverse rib 101 transversely penetrate through the upper end of the fixing plate 31, and the plurality of positioning slots 311 and the plurality of first welding seats 20 are arranged in a one-to-one correspondence manner; the push plate 32 is disposed on the frame 1 in a laterally slidable manner and is used for pushing the transverse rib 101 in the positioning slot 311 to move to the upper end of the first soldering base 20. During operation, the transverse rib 101 is manually placed into the positioning groove 311, so that the transverse rib 101 and the first welding seat 20 can be positioned; and the push plate 32 is contacted with one end of the transverse rib 101 far away from the first welding seat 20, so that the transverse ribs 101 are aligned with each other; pushing the push plate 32 forces the plurality of transverse ribs 101 to move transversely, so that the plurality of transverse ribs 101 are conveyed to the plurality of first soldering bases 20 in a one-to-one correspondence manner. A plurality of stoppers 33 set up in frame 1 to arrange between first welding seat 20 and constant head tank 311 in the one-to-one, and be equipped with the spacing hole that is used for single horizontal muscle 101 to pass on stopper 33, under the limiting displacement in spacing hole, can avoid making horizontal muscle 101 take place the displacement when welding operation, thereby when guaranteeing next welding operation, positioning accuracy between horizontal muscle 101 and the first welding seat 20. One end of the limiting hole far away from the first welding seat 20 gradually extends outwards in the radial direction to form a funnel-shaped structure 331, and under the action of the funnel-shaped structure 331, the transverse rib 101 can be facilitated to penetrate through the limiting hole. It should be noted that, when the longitudinal interval between two adjacent transverse ribs 101 is small, a staggered arrangement (as shown in fig. 5) is adopted between two adjacent funnel-shaped structures 331.

Referring to fig. 6 to 12, in some embodiments of the present application, the second feeding mechanism 4 includes a supporting frame 41, a rotating disc 42, a sliding frame 43, and a limiting frame 44, the rotating disc 42 is rotatably disposed on the supporting frame 41, an axis of the rotating disc 42 is arranged along a longitudinal direction, and a receiving groove 421 for receiving the single longitudinal rib 102 is axially penetratingly disposed on an outer circumferential surface of the rotating disc 42; the sliding frame 43 is obliquely arranged on the supporting frame 41, and the lower end of the sliding frame 43 extends to the upper part of the first welding seat 20; the limiting frame 44 is an arc-shaped structure, the limiting frame 44 is arranged on the supporting frame 41, and a limiting area 402 for limiting the longitudinal rib 102 to be separated from the accommodating groove 421 is formed between the inner arc surface of the limiting frame 44 and the outer annular surface of the turntable 42; a limit stop rod 441 extends from the upper end of the limit frame 44, a storage area 401 for storing the longitudinal rib 102 is formed between the limit stop rod 441 and the sliding frame 43, and a discharge area 403 is formed between the lower end of the limit frame 44 and the sliding frame 43. As shown in fig. 10, a plurality of longitudinal ribs 102 are stored in the storage area 401, when the receiving groove 421 rotates with the turntable 42 to the position of the storage area 401, one longitudinal rib 102 in the storage area 401 slides into the receiving groove 421 and rotates with the turntable 42 (during the rotation of the longitudinal rib 102 with the turntable 42, the longitudinal rib 102 is prevented from separating from the receiving groove 421 due to the limiting effect of the limiting area 402), until the longitudinal rib 102 returns to the sliding frame 43 again through the unloading area 403, and then rolls down to the upper end of the first soldering nest 20 along the sliding frame 43 under the action of its own gravity (as shown in fig. 12).

The present application does not limit the installation manner in which the turntable 42 is rotatably installed on the support frame 41, for example: as shown in fig. 8-9, the driving manner of the stepping motor 422 may be adopted, that is, the stepping motor 422 is mounted on the supporting frame 41 through the motor support 423, and the output shaft of the stepping motor 422 is coaxially and fixedly connected with the turntable 42, so that the rotation angle of the turntable 42 can be precisely controlled through the stepping motor 422.

Referring to fig. 9, in some embodiments of the present application, there are at least two (three in the drawings) turntables 42, at least two turntables 42 are coaxially arranged one above the other, and the turntables 42 are rotatable relative to each other. The application does not limit the relative rotation between the turntables 42, for example: when the stepping motor 422 is used for driving, the three turntables 42 can be screwed and fixed on the output shaft of the stepping motor 422 through nuts; when the nut is unscrewed, the offset angle between two adjacent receiving grooves 421 can be adjusted by rotation, so as to adapt to the longitudinal ribs 102 with different diameters.

Referring to fig. 8-10, in some embodiments of the present application, the turntable 42, the sliding frame 43, and the limiting frame 44 are all longitudinally slidably disposed on the supporting frame 41. According to the actual length of the longitudinal rib 102, the longitudinal positions of the formed storage area 401, the limiting area 402 and the discharging area 403 can be adjusted by longitudinally sliding and adjusting the positions of the turntable 42, the sliding frame 43 and the limiting frame 44, so that the position of the longitudinal rib 102 rolled onto the first welding seat 20 is changed. In addition, in order to improve the supporting effect on the longer longitudinal rib 102, the number of the sliding frames 43 and the limiting frames 44 can be increased; meanwhile, a positioning stop 431 (shown in fig. 8 or 10) may be further provided on one of the sliding frames 43 located at the outer side, and when the longitudinal ribs 102 are inserted into the storage area 401 through the positioning stop 431, one end of the longitudinal rib 102 is in contact with the positioning stop 431, so that the longitudinal ribs 102 are aligned with each other. The sliding installation mode of the turntable 42, the sliding frame 43 and the limiting frame 44 is not limited in the application, for example: the motor support 423, the sliding frame 43 and the limiting frame 44 may be provided with a limiting sliding groove 404, the supporting frame 41 is longitudinally provided with a limiting sliding rail 405 for slidably connecting the limiting sliding groove 404, and the limiting sliding groove 404 is locked on the limiting sliding rail 405 by a bolt.

Referring to fig. 6-7, in some embodiments of the present application, the second feeding mechanism 4 further includes a blocking member 45, the blocking member 45 includes a rotating shaft 451 and a blocking rod 452, the rotating shaft 451 is rotatably disposed on the supporting frame 41, and the rotating shaft 451 is longitudinally disposed above the sliding frame 43 and penetrates through the limiting frame 44; one end of the stopper 452 is disposed on the outer circumferential surface of the rotation shaft 451. As shown in fig. 10, when the rotating shaft 451 is rotated and the other end of the abutting lever 452 is forced to approach the sliding frame 43, the longitudinal rib 102 of the sliding frame 43 is restricted from rolling down. On one hand, the gravitational potential energy of the longitudinal rib 102 can be reduced, and the situation that the longitudinal rib 102 cannot stop on the first welding seat 20 due to the fact that the speed of rolling down the upper end of the first welding seat 20 is too high is avoided; on the other hand, one longitudinal rib 102 may be fed in advance into contact with the stopper 452 at the same time as the welding operation, so as to improve the feeding efficiency of the longitudinal rib 102. In addition, the present application does not limit the rotatable mounting manner between the supporting frame 41 and the rotating shaft 451, for example: as shown in fig. 7, both ends of the rotating shaft 451 are rotatably mounted on the supporting frame 41, the supporting frame 41 is hinged with the push cylinder 453, the telescopic end of the push cylinder 453 is hinged with the push arm 454, and the other end of the push arm 454 is fixed on the rotating shaft 451, so that the rotating shaft 451 can be driven to rotate by controlling the extension and contraction of the push cylinder 453.

Referring to fig. 12-13, in some embodiments of the present application, the second feeding mechanism 4 further includes a detecting member 46 for detecting whether the longitudinal rib 102 is present on the first soldering nest 20, so that when the longitudinal rib 102 does not normally roll down on the first soldering nest 20, the detecting member 46 can timely detect the longitudinal rib 102, and thus timely stop the soldering operation. The detecting element 46 includes a supporting block 461, a rotating arm 462, a return spring 463 and a sensor 464, wherein the supporting block 461 is disposed on the frame 1 and located between two adjacent first welding seats 20; the middle portion of the pivoting arm 462 is pivotally connected to the supporting block 461, the other end of the pivoting arm 462 is formed with a limiting groove 4621, and the other end of the pivoting arm 462 is connected to the supporting block 461 through a return spring 463. Under the action of the return spring 463, the rotating arm 462 is forced to rotate until the limiting groove 4621 is engaged with the lower end of the sliding frame 43 (as shown in fig. 12), so that the longitudinal rib 102 rolled on the sliding frame 43 can fall into the limiting groove 4621; on one hand, the limiting groove 4621 can limit the longitudinal rib 102 from moving laterally, and on the other hand, under the action of the self gravity of the longitudinal rib 102, the rotating arm 462 is forced to rotate, and can be detected by the sensor 464 arranged on the supporting block 461, so as to determine whether the longitudinal rib 102 normally falls on the first soldering nest 20. In addition, since the supporting block 461 (i.e., the rotating arm 462) is located between two adjacent first welding seats 20, the welding operation of the second welding seat 21 is not affected; moreover, after the welding operation, the longitudinal rib 102 is connected to the plurality of transverse ribs 101, and the whole weight of the transverse ribs 101 acts on the limiting groove 4621 through the longitudinal rib 102, so that the rotating arm 462 is forced to further rotate, and the longitudinal rib 102 can be separated from the limiting groove 4621 along one end (i.e. along the left end in fig. 12) far away from the first feeding mechanism 3; after the longitudinal rib 102 is disengaged from the position-limiting groove 4621, the position-limiting groove 4621 is rotated to engage with the lower end of the sliding frame 43 along with the rotating arm 462 by the action of the return spring 463. It should be noted that the sensor 464 itself and the working principle thereof belong to the prior art, and therefore are not described herein again.

Referring to fig. 14-15, in some embodiments of the present application, the second feeding mechanism 4 further includes a pushing block 47 for pushing the longitudinal rib 102 on the first welding seat 20 to move longitudinally, and the pushing block 47 is longitudinally slidably disposed on the frame 1. When the longitudinal rib 102 rolls down to the upper end of the first welding seat 20, the pushing block 47 is controlled to push the longitudinal rib 102 to displace, so that the positioning accuracy between the longitudinal rib 102 and the transverse rib 101 is improved.

The sliding installation mode of the pushing block 47 and the up-and-down movable installation mode of the second welding seat 21 are not limited in the present application, and only two modes are provided below for reference:

the first embodiment is as follows: as shown in fig. 14-18, the device comprises a first driving mechanism 7 for driving the second welding seat 21 to move up and down and a second driving mechanism 8 for driving the pushing block 47 to slide longitudinally. As shown in fig. 14 and fig. 17 to 18, the first driving mechanism 7 includes a driving shaft 71, a fixed frame 72, a first cam 73, a pull rod 74 and a pressure spring 75, the driving shaft 71 is longitudinally arranged on the frame 1, and the first cam 73 is arranged on the driving shaft 71; the plurality of second welding seats 21 are longitudinally arranged on the fixing frame 72 at intervals, and the fixing frame 72 is arranged on the machine frame 1 in a vertically sliding manner; the pull rod 74 is arranged on the frame 1 in a vertically sliding manner, and the upper end of the pull rod 74 is connected with the fixed frame 72; the compression spring 75 is disposed on the frame 1, and forces the lower end of the pull rod 74 to contact the outer circumferential surface of the first cam 73 (for example, the compression spring 75 generates a downward pressure on the pull rod 74 through a stopper ring 741 fixed to the pull rod 74). As shown in fig. 14 to 16, the second driving mechanism 8 includes a second cam 81, a pressing arm 82, a tension spring 83, a V-shaped arm 84, a first connecting arm 85, a second connecting arm 86 and a limiting slider 87, the second cam 81 is disposed on the driving shaft 71, and one end of the pressing arm 82 is hinged to the frame 1; the tension spring 83 is arranged between the frame 1 and the pressure arm 82 and forces the pressure arm 82 to contact with the outer annular surface of the second cam 81; the middle part of the V-shaped arm 84 is hinged on the frame 1, one end of the V-shaped arm 84 is hinged on the upper end of the first connecting arm 85, and the lower end of the first connecting arm 85 is hinged on the other end of the pressing arm 82; the other end of the V-shaped arm 84 is hinged to one end of a second connecting arm 86, the other end of the second connecting arm 86 is hinged to the pushing block 47, and the pushing block 47 is longitudinally connected to the machine frame 1 in a sliding mode through a limiting sliding block 87. When the driving shaft 71 rotates, the first cam 73 and the second cam 81 rotate synchronously, the pressure spring 75 can force the pull rod 74 to change periodically in the vertical direction, and the tension spring 83 can force the pressure arm 82 to swing periodically, so that when the pull rod 74 drives the second welding seat 21 to perform a downward welding operation through the fixed frame 72, the pressure arm 82 can drive the pushing block 47 to complete a material pushing operation sequentially through the first connecting arm 85, the V-shaped arm 84 and the second connecting arm 86, and the whole process is simple to control and has good stability. It should be noted that the installation manner of the driving shaft 71 is the prior art, that is, the driving shaft 71 is installed and fixed on the frame 1 through a bearing, and the driving shaft 71 is driven to rotate through a motor and a transmission mechanism; in addition, the sliding modes between the frame 1, the pull rod 74 and the fixing frame 72 are all the prior art, and are realized by adopting the limiting sliding fit between the sliding grooves and the sliding blocks.

In the first embodiment, as shown in fig. 12, the second soldering nest 21 includes a rod-shaped body 211, a first fixing block 212, a second fixing block 213, a fixing bolt 214 and a buffer spring 215, the fixing frame 72 is hollow along the vertical direction, the first fixing block 212 is located at the upper end of the fixing frame 72, the second fixing block 213 is located at the lower end of the fixing frame 72, and the fixing bolt 214 is disposed between the first fixing block 212 and the second fixing block 213 and forces the fixing frame 72 to be clamped between the first fixing block 212 and the second fixing block 213; mounting holes are arranged on the first fixing block 212 and the second fixing block 213 in a penetrating manner along the vertical direction; the rod-shaped body 211 is arranged in the mounting hole in a vertically sliding manner, the upper end of the rod-shaped body 211 is provided with a limiting part 2111, and the lower end of the rod-shaped body 211 is positioned below the mounting hole; the buffer spring 215 is sleeved on the rod-shaped body 211 and located between the first fixing block 212 and the second fixing block 213, and is used for forcing the rod-shaped body 211 to slide downwards until the limiting portion 2111 contacts the mounting hole.
