After welding, the pushing element 339 can drive the pinning elements 3391 away from the positioning block 337.
FIGS. 4-5 illustrates that the welding mechanism 40 can include a cylinder assembly 41, a driving plate 43, a supporting plate 45; a welding assembly 47, a plurality of pressing assemblies 48, and a plurality of cutting assemblies 49 connected to the cylinder assembly 41. The welding mechanism 40 can be installed on the third supporting element 15. The cylinder assembly 41 can include a first air cylinder 411, a second air cylinder 413, a third air cylinder 415, and a fourth air cylinder 417. The first air cylinder 411 can be installed on the third supporting element 15, and the driving plate 43 can be fixed on the first air cylinder 411 thereby vertically moving with the first air cylinder 411. The supporting plate 45 can be positioned on the driving plate 43 thereby moving with the driving plate 43. The supporting plate 45 further include a holding plate 451, and the pressing assembly 48 and cutting assembly 49 can be positioned on the holding plate 451. The welding assembly 47 can be configured to weld the first feeding belt 200 and second feeding belt 300 (as shown in FIGS. 1-2), and the pressing assembly 48 can be configured to flatten the welded belts. The second air cylinder 413 can be installed on the supporting plate 45 and connected to the holding plate 451, to push the holding plate 451, the welding assembly 47, and the pressing assembly 48 positioned on the holding plate 451 to move horizontally with the second air cylinder 413.
The cutting assembly 49 can be positioned on the supporting plate 45 and adjacent to the welding assembly 47. The third air cylinder 415 can be located on a side of the cutting assembly 49 facing the welding assembly 47, to push the cutting assembly 49 to horizontally move to the welding assembly 47. The fourth air cylinder 417 can be installed on the driving plate 43 and under the cutting assembly 49, to push the cutting assembly 49 to vertically move to the welding assembly 47 and cut off superfluous parts of the belts.
After the belts are engaged by the pinning elements 3391 (as shown in FIG. 3), the cylinder assembly 41 can push the welding assembly 47 and the pressing assembly 48 to move to the positioning block 337 of the positioning assembly 33 which is furthest from the bracket 10 (as shown in FIG. 1), to weld the belts.
In welding, the first air cylinder 411 drives the driving plate 43 to move and welding assembly 47 can move to face and be square with the positioning assembly 33. Then, the second air cylinder 413 can push the welding assembly 47 to move to the positioning assembly 33 to weld the belts and transmit the welded belts after flattening by the pressing assembly 48, to the next manufacturing process. After a welding of the belts, the second air cylinder 413 can reset the welding assembly 47 and the pressing assembly 48. The second air cylinder 413 can push the cutting assembly 49 downward towards the welding assembly 47, and the fourth air cylinder 417 can push the cutting assembly 49 toward the welding assembly 47 to cut off superfluous parts of the welded belts.
After the welding of the belts farthest from the bracket 10 (as shown in FIG. 1), the feeding assembly 23 between the other two can transmit the belts to the middle positioning assembly 33, and the cylinder assembly 41 can push the welding assembly 47 to the middle positioning assembly 33 to weld the belts.
After the welding of the belts transmitted by the feeding assembly 23 which is in the middle, the positioning assembly 33 nearest the bracket 10 can receive the belts from the feeding assembly 23 nearest the bracket 10 (as shown in FIG. 1). The cylinder assembly 41 can push the welding assembly 47 to the positioning assembly 33 nearest the bracket 10 to weld the belts (as shown in FIG. 1).
When welding of the belts of each feeding assembly 23 of the feeding mechanism 20 is completed, a welding process is finished and a plurality of belts can be continuously added or incorporated to be welded in a next welding process.
As the welding device 100 can include a control unit 50 and a feeding mechanism 20, a positioning mechanism 30, a welding mechanism 40 controlled by the control unit 50 (as shown in FIG. 1), the welding device 100 can improve the efficiency and reduce the labor cost of the manufacturing process.
