[0025] Compared with the prior art, the present invention has the following advantages and effects: the material-taking mechanism is used to place the steel wire welded to the bent and formed Bondi tube in a loading box and is mounted on two shaking rods. The shaking of the shaking cylinder can make the steel wire go down more smoothly into the outlet of the loading box. The steel wire at the outlet of the loading box is taken away by the rotation of the material-taking disc group, and then the steel wire on the material-taking disc group is taken away by the wire feeding piece. The wire feeding piece sends the steel wire to the welding mechanism of the condenser tube welder. The steel wire can be taken away conveniently and the material-taking efficiency is high.

[0026] The Bondi tube feeding and returning device is used to feed the Bondi tube that needs to be welded with steel wire to the welding mechanism of the condenser tube welder, and to retract the Bondi tube that has been welded with steel wire from the welding mechanism, that is, it is used for feeding and returning the Bondi tube to the condenser tube welder during welding. Under the push and pull action of the workstation switching cylinder, the No. 1 hanging rail and the No. 2 hanging rail work alternately. For example, the No. 1 pushing cylinder controls the No. 1 pushing material to send the No. 1 Bondi tube carrier located on the No. 1 hanging rail and with the Bondi tube hung on it into the carrier carrying beam of the vertical feeding and returning support frame. The stepper motor controls the carrier carrying beam to rise step by step, and the steel wire is welded to the Bondi tube through the welding mechanism of the condenser tube welder. Every time the carrier carrying beam rises one step, the welding mechanism is at the corresponding position on both sides of the Bondi tube. Each welds a steel wire, and at the same time, the worker can hang the next batch of Bondi tubes to be welded on the No. 2 Bondi tube carrier as a backup; when the Bondi tubes hung on the No. 1 Bondi tube carrier are welded and returned to the No. 1 material trough of the No. 1 hanging rail, the No. 2 pushing cylinder controls the No. 2 pushing material to send the No. 2 Bondi tube carrier with the Bondi tubes on the No. 2 hanging rail into the carrier carrying beam of the vertical return material support frame, and the steel wire is welded to the Bondi tube through the welding mechanism of the condensing tube welder. At the same time, the worker first removes the welded Bondi tubes from the No. 1 Bondi tube carrier, and then hangs the next batch of Bondi tubes to be welded on the No. 1 Bondi tube carrier as a backup; this cycle is carried out, and the efficiency of feeding and returning is high.

[0027] The welding mechanism controls the forward and backward movement of the bottom plate through the bottom plate push-pull structure. When it is necessary to weld steel wire on the bent Bundy tube, the bottom plate push-pull structure pushes the bottom plate forward, and the bottom plate drives the welding structure to move forward synchronously, and a steel wire is welded to the bent Bundy tube through the copper electrode rod on the welding structure; after the welding of one steel wire is completed, the bottom plate push-pull structure pulls the bottom plate backward, and the bottom plate drives the welding structure to move backward synchronously, and the bent Bundy tube is lifted up for a section, and then the bottom plate push-pull structure pushes the bottom plate forward again, and the bottom plate drives the welding structure to move forward synchronously again, and the second steel wire is welded to the corresponding position of the bent Bundy tube again through the copper electrode rod on the welding structure; the bottom plate push-pull structure pushes and pulls back and forth in this way, and the Bundy tube to be welded is gradually lifted, so that the corresponding positions of the entire Bundy tube are welded with steel wires, and the welding efficiency is high.

The racks 103 can slide backward starting from the Bondi tube feeding device 101, which is convenient for maintenance and repair of the condenser tube welder.

[0049] The material picking mechanism 106 in this embodiment includes a loading box 1, a material box fixing plate 2, a material box width adjustment plate 3, a width adjustment rod 4, a width positioning member 5, a material shaking cylinder 6, a material shaking drive rod 7, two material shaking rods 8, a servo motor No. 1 9, a reducer No. 10, a coupling 11, a driving shaft 12, a driving wheel 13, a synchronous belt 14, a driven wheel 15, a driven shaft 16, a material picking disc group 17, a wire feeding member 18, and a mechanism positioning member 22 for fixing the material picking mechanism 106 to the condenser tube welding machine, wherein the upper part of one side of the loading box 1 is the entrance, and the lower part of the other side is the outlet.

[0050] The shaking cylinder 6 in this embodiment is fixed on one side of the charging box 1, and the shaking driving rod 7 is connected to the piston rod of the shaking cylinder 6. The shaking driving rod 7 is parallel to the active rotating shaft 12, and the shaking cylinder 6 can drive the shaking driving rod 7 to shake up and down. The upper part of the shaking rod 8 is mounted on the shaking driving rod 7, and the up and down shaking of the shaking driving rod 7 can drive the upper part of the shaking rod 8 to shake up and down, and the lower end of the shaking rod 8 is against the bottom of the charging box 1, and the steel wire 100 as the material is mounted on the two shaking rods 8. The upper part of the shaking rod 8 can be shaken up and down to make the steel wire 100 as the material fall smoothly to the outlet of the charging box 1, thereby preventing the steel wire 100 from staying in the charging box 1 due to friction assistance, resulting in no steel wire 100 at the outlet of the charging box 1.

[0051] In this embodiment, the No. 1 servo motor 9 is fixed to the other side of the charging box 1 through the No. 1 reducer 10, the coupling 11 is connected to the No. 1 reducer 10, and a driving shaft 12 is fixed to one end of the driving wheel 13. The other end of the driving shaft 12 is connected to the coupling 11. The driving shaft 12 is installed on the charging box 1 through a bearing near the driving wheel 13. The No. 1 reducer 10 is rotated by the No. 1 servo motor 9, and the No. 1 reducer 10 drives the coupling 11 to rotate. The driving shaft 12 is rotated under the rotation of the coupling 11, and then the driving shaft 12 drives the driving wheel 13 to rotate.

[0052] The feeding disc group 17 in this embodiment includes at least three feeding discs, and a number of feeding notches are evenly arranged on the circumference of each feeding disc. The corresponding feeding notches on all the feeding discs are aligned to form a row of feeding notches. A magnet for attracting the steel wire 100 is provided in each feeding notch. The steel wire 100 can be attracted to the feeding notch under the action of the magnet, and a steel wire 100 is attracted to a row of relatively aligned feeding notches. The feeding disc group 17 is fixed on the active rotating shaft 12, and the rotation of the active rotating shaft 12 can drive the feeding disc group 17 to rotate, and the feeding disc group 17 cooperates with the outlet of the charging box 1. When the feeding disc group 17 rotates with the active rotating shaft 12, when a row of relatively aligned feeding notches on the feeding disc group 17 passes through the outlet of the charging box 1, the relatively aligned row of feeding notches can attract a steel wire 100 under the action of the magnet. As the active rotating shaft 12 continues to rotate, the relatively aligned rows of feeding notches on the feeding disc group 17 will successively attract a steel wire 100 from the outlet of the charging box 1, thereby completing the feeding of the steel wire 100.

[0053] The driven rotating shaft 16 in this embodiment is mounted on the charging box 1 through a bearing. The driven rotating shaft 16 is parallel to the driving rotating shaft 12. The driven wheel 15 is fixed to one end of the driven rotating shaft 16. The driven wheel 15 and the driving wheel 13 are connected by a synchronous belt 14. When the driving wheel 13 rotates, the driving wheel 13 drives the driven wheel 15 to rotate through the synchronous belt 14, and then the driven wheel 15 drives the driven rotating shaft 16 to rotate.

[0054] The number of the steel wire feeding pieces 18 in this embodiment is at least two, and the steel wire feeding piece 18 is cross-shaped, and the cross-shaped steel wire feeding piece 18 has four ends, namely, upper, lower, left, and right. Magnets for attracting the steel wire 100 are fixed at the four ends of the cross-shaped steel wire feeding piece 18. The magnetism of the magnet fixed here is greater than the magnetism of the magnet fixed in the feeding notch of the feeding disc, so that the four ends of the steel wire feeding piece 18 can take away the steel wire 100 attracted on the feeding disc group 17 in turn. The center of the wire feeder 18 is fixed to the driven shaft 16. The rotation of the driven shaft 16 can drive the wire feeder 18 to rotate. The wire feeder 18 cooperates with the feeding disc assembly 17. When the wire feeder 18 rotates with the driven shaft 16 and the feeding disc assembly 17 rotates with the driving shaft 12, the four ends of the wire feeder 18 can take turns to remove the steel wire 100 sucked on the feeding disc assembly 17. Then, each row of feeding notches on the feeding disc assembly 17 sequentially sucks the steel wire 100 from the outlet of the charging box 1. The steel wire 100 on the wire feeder 18 will be welded to the Bondi tube 200 by the welding mechanism 107 of the condenser tube welder.

[0055] In this embodiment, the magazine fixing plate 2 is fixed within the magazine 1. The magazine fixing plate 2 is perpendicular to the driving shaft 12. The width adjustment rod 4 is fixed within the magazine 1. The width adjustment rod 4 is parallel to the driving shaft 12. The magazine width adjustment plate 3 can move along the width adjustment rod 4. The magazine width adjustment plate 3 is parallel to the magazine fixing plate 2. When moved to the desired position, the magazine width adjustment plate 3 is fixed to the width adjustment rod 4 by the width positioning member 5. An area for placing the steel wire 100 is formed between the magazine fixing plate 2 and the magazine width adjustment plate 3. The two shaking rods 8 are located in this area. By moving the magazine width adjustment plate 3 along the width adjustment rod 4, the distance between the magazine width adjustment plate 3 and the magazine fixing plate 2 can be changed. The distance between the magazine width adjustment plate 3 and the magazine fixing plate 2 is equal to or slightly greater than the length of the steel wire 100. Therefore, the position of the magazine width adjustment plate 3 can be adjusted according to the specifications of the steel wire 100 to accommodate steel wires 100 of different specifications.

[0056] The material taking mechanism 106 in this embodiment may further include a steel wire alignment cylinder 19, which is fixed to the other side of the charging box 1. The steel wire alignment cylinder 19 cooperates with the steel wire 100 at the outlet of the charging box 1. Under the action of the steel wire alignment cylinder 19, the steel wire 100 at the outlet of the charging box 1 can be aligned more neatly. Of course, the steel wire alignment cylinder 19 may not be provided in the present invention, because based on the premise that the distance between the material box width adjustment plate 3 and the material box fixing plate 2 is equal to or slightly greater than the length of the steel wire 100, the steel wire 100 at the outlet of the charging box 1 is already aligned.

[0057] The picking mechanism 106 in this embodiment may further include a detection member crossbeam 20 and a detection member 21. The detection member crossbeam 20 is fixed on the charging box 1, and the detection member 21 is fixed on the detection member crossbeam 20. The detection member 21 is located directly above the picking disc group 17. The detection member 21 is used to detect whether the picking disc group 17 has sucked the steel wire 100. Of course, the detection member crossbeam 20 and the detection member 21 may not be provided in the present invention, because under the action of the shaking cylinder 6, the shaking drive rod 7 and the shaking rod 8, there will always be a steel wire 100 at the outlet of the charging box 1, and the picking disc group 17 will not fail to suck the steel wire 100.
