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.

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 (in the process that the longitudinal rib 102 rotates 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 through the unloading area 403, and then rolls down to the upper end of the first welding seat 20 along the sliding frame 43 under the self 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 in a stacked manner, and the turntables 42 can rotate 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 rack 43, and the limiting rack 44 are all longitudinally slidably disposed on the supporting rack 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 adjusting the positions of the turntable 42, the sliding frame 43 and the limiting frame 44 in a longitudinal sliding manner, so that the position of the longitudinal rib 102 rolling 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 (see fig. 8 or fig. 10) may be further provided on one of the sliding frames 43 located at the outer side, and when the longitudinal rib 102 is placed into the storage area 401, one end of the longitudinal rib 102 contacts the positioning stop 431 through the positioning stop 431, so as to ensure the alignment between the longitudinal ribs 102. 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 rotating shaft 451 and the supporting frame 41, for example: as shown in fig. 7, both ends of the rotation shaft 451 are rotatably mounted on the support frame 41, the push cylinder 453 is hinged to the support frame 41, the push arm 454 is hinged to the telescopic end of the push cylinder 453, and the other end of the push arm 454 is fixed to the rotation shaft 451, so that the rotation 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.
