Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0023] Example

[0024] See Figures 1 to 9The material handling mechanism of the condenser tube welding machine in this embodiment includes a material box 1, a material box fixing plate 2, a material box width adjusting plate 3, a width adjusting rod 4, a width positioning component 5, a material shaking cylinder 6, a material shaking drive rod 7, two material shaking rods 8, a servo motor 9, a reducer 10, a coupling 11, a drive shaft 12, a drive wheel 13, a synchronous belt 14, a driven wheel 15, a driven shaft 16, a material handling disc assembly 17, a wire feeding component 18, and a mechanism positioning component 22 for fixing the material handling mechanism to the condenser tube welding machine. The upper part of one side of the material box 1 is the inlet, and the lower part of the other side is the outlet.

[0025] In this embodiment, the shaking cylinder 6 is fixed to one side of the loading box 1. The shaking drive rod 7 is connected to the piston rod of the shaking cylinder 6. The shaking drive rod 7 is parallel to the active rotating shaft 12. The shaking cylinder 6 can drive the shaking drive rod 7 to shake up and down. The upper part of the shaking rod 8 is mounted on the shaking drive rod 7. The up and down shaking of the shaking drive rod 7 can drive the upper part of the shaking rod 8 to shake up and down. The lower end of the shaking rod 8 is against the bottom of the loading box 1. The steel wire 100, which is the material, is mounted on the two shaking rods 8. The up and down shaking of the upper part of the shaking rod 8 can make the steel wire 100, which is the material, fall smoothly to the outlet of the loading box 1, preventing the steel wire 100 from staying in the loading box 1 due to friction, resulting in no steel wire 100 at the outlet of the loading box 1.

[0026] In this embodiment, the servo motor 9 is fixed to the other side of the loading box 1 via the reducer 10. The coupling 11 is connected to the reducer 10. One end of the drive shaft 12 is fixed with the drive wheel 13. The other end of the drive shaft 12 is connected to the coupling 11. The drive shaft 12 is mounted on the loading box 1 via bearings near the drive wheel 13. The servo motor 9 drives the reducer 10 to rotate, and the reducer 10 drives the coupling 11 to rotate. The rotation of the coupling 11 drives the drive shaft 12 to rotate, and the drive shaft 12 drives the drive wheel 13 to rotate.

[0027] The material picking disc group 17 in this embodiment includes at least three material picking discs. Each material picking disc has several material picking notches evenly arranged on its circumference. The corresponding material picking notches on all the material picking discs are aligned to form a row of material picking notches. Each material picking notch is provided with a magnet for attracting the steel wire 100. The steel wire 100 can be attracted into the material picking notch under the action of the magnet. One steel wire 100 is attracted to a relatively aligned row of material picking notches. The material-picking disc assembly 17 is fixed on the drive shaft 12. The rotation of the drive shaft 12 drives the material-picking disc assembly 17 to rotate. The material-picking disc assembly 17 is matched with the outlet of the loading box 1. When the material-picking disc assembly 17 rotates with the drive shaft 12, when the row of aligned material-picking notches on the material-picking disc assembly 17 passes through the outlet of the loading box 1, the row of aligned material-picking notches can attract a steel wire 100 under the action of a magnet. As the drive shaft 12 continues to rotate, the row of aligned material-picking notches on the material-picking disc assembly 17 will successively attract a steel wire 100 from the outlet of the loading box 1, thereby completing the picking of the steel wire 100.

[0028] In this embodiment, the driven shaft 16 is mounted on the loading box 1 via bearings. The driven shaft 16 is parallel to the driving shaft 12. The driven wheel 15 is fixed to one end of the driven 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 will drive the driven wheel 15 to rotate via the synchronous belt 14, and then the driven wheel 15 will drive the driven shaft 16 to rotate.

[0029] In this embodiment, there are at least two wire feeders 18. Each wire feeder 18 is cross-shaped and has four ends: top, bottom, left, and right. Magnets for attracting wires 100 are fixed at each of the four ends of the cross-shaped wire feeder 18. The magnets fixed at these ends have a stronger magnetism than the magnets fixed in the material-retrieving notches of the material-retrieving disc, so that the four ends of the wire feeder 18 can sequentially remove the wires 100 attracted to the material-retrieving disc assembly 17. The center of the wire feeder 18 is fixed on the driven rotating shaft 16. The rotation of the driven rotating shaft 16 drives the wire feeder 18 to rotate. The wire feeder 18 cooperates with the material picking disc assembly 17. When the wire feeder 18 rotates with the driven rotating shaft 16 and the material picking disc assembly 17 rotates with the driving rotating shaft 12, the four ends of the wire feeder 18 can take away the wires 100 attracted to the material picking disc assembly 17 in turn. Then, each row of material picking notches on the material picking disc assembly 17 will sequentially pick up the wires 100 from the outlet of the loading box 1. The wires 100 on the wire feeder 18 will be welded to the Bundy tube 200 by the welding mechanism of the condenser tube welding machine. It is common knowledge to those skilled in the art that wires 100 need to be welded to the Bundy tube 200.

[0030] In this embodiment, the material box fixing plate 2 is fixed inside the material box 1. The material box fixing plate 2 is perpendicular to the drive shaft 12. The width adjusting rod 4 is fixed inside the material box 1 and is parallel to the drive shaft 12. The material box width adjusting plate 3 can move along the width adjusting rod 4. The material box width adjusting plate 3 is parallel to the material box fixing plate 2. When it moves to the desired position, the material box width adjusting plate 3 is fixed to the width adjusting rod 4 by the width positioning member 5. An area for placing the steel wire 100 is formed between the material box fixing plate 2 and the material box width adjusting plate 3. The two shaking rods 8 are located in this area. By moving the material box width adjusting plate 3 along the width adjusting rod 4, the distance between the material box width adjusting plate 3 and the material box fixing plate 2 can be changed. The distance between the material box width adjusting plate 3 and the material box fixing plate 2 is equal to or slightly greater than the length of the steel wire 100. Therefore, the position of the material box width adjusting plate 3 can be adjusted according to the specifications of the steel wire 100 to accommodate steel wires of different specifications.

[0031] The material handling mechanism in this embodiment may further include a wire alignment cylinder 19, which is fixed to the other side of the material box 1. This cylinder 19 cooperates with the wire 100 at the outlet of the material box 1. Under the action of the wire alignment cylinder 19, the wire 100 at the outlet of the material box 1 can be aligned more neatly. Alternatively, the wire alignment cylinder 19 may not be provided in this 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 wire 100, the wire 100 at the outlet of the material box 1 is already aligned.

[0032] The material handling mechanism in this embodiment may further include a detection beam 20 and a detection element 21. The detection beam 20 is fixed on the loading box 1, and the detection element 21 is fixed on the detection beam 20. The detection element 21 is located directly above the material handling disc assembly 17 and is used to detect whether the material handling disc assembly 17 has attracted the steel wire 100. Of course, the detection beam 20 and the detection element 21 may not be provided in this utility model, because under the action of the shaking cylinder 6, the shaking drive rod 7, and the shaking rod 8, there will always be steel wire 100 at the outlet of the loading box 1, and the material handling disc assembly 17 will not fail to attract the steel wire 100. The detection by the detection element 21 is an additional verification process.

[0033] In this embodiment, the mechanism positioning component 22 is fixed on the material box 1, and the material picking mechanism can be fixed to the condenser tube welding machine through the mechanism positioning component 22.

[0034] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in these claims, all of which should fall within the protection scope of this utility model.
