DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] refer to Figure 1-3 As shown, the utility model provides a device for welding a refrigerator hinge shaft, comprising: a loading mechanism, a welding mechanism and a unloading mechanism installed on a gantry 1, the gantry 1 is provided with a relatively rotating shaft 9, a plurality of processing stations are distributed in a circular array on the outer periphery of the rotating shaft 9, and based on the relative rotation, the plurality of processing stations can pass through the loading mechanism, the welding mechanism and the unloading mechanism in sequence.

[0027] In the present utility model, combined with Figure 1 As shown, a second motor 8 for driving the rotating shaft 9 to rotate is also installed on the gantry 1 of this embodiment.

[0028] As described above, when using the gantry 1, feeding mechanism, welding mechanism, unloading mechanism and second motor 8 provided by the utility model, the rotating shaft 9 is rotatably installed on the gantry 1 through the second motor 8, and the feeding mechanism, welding mechanism and unloading mechanism are respectively installed at different positions of the rotating direction of the rotating shaft 9. The rotating rotating shaft 9 can make the hinge seat 7 pass through the feeding mechanism, welding mechanism and unloading mechanism in sequence. When the hinge seat 7 passes through the feeding mechanism, the rotating shaft rod 13 is automatically assembled on the hinge seat 7 through the feeding mechanism. When the hinge seat 7 is at the welding mechanism, the rotating shaft rod 13 and the hinge seat 7 are welded by the welding mechanism. When the welded hinge is at the unloading mechanism, the hinge is separated from the rotating shaft 9 by the unloading mechanism. The equipment realizes the functions of automatic assembly, automatic welding and automatic unloading of hinges.

[0029] Further, in order to detachably mount the hinge seat 7 on the rotating shaft 9, refer to Figure 2 As shown, a placement seat 10 is installed in each processing station, and a magnet 18 is embedded and installed on the side of each placement seat 10 away from the rotating shaft 9, and the hinge seat 7 is magnetically attracted to the outer side of the magnet 18. The placement seat 10 provides an installation position on the rotating shaft 9, and the hinge seat 7 is restricted on the placement seat 10 by the magnet 18, so as to prevent the hinge seat 7 from being separated from the placement seat 10 when the rotating shaft 9 rotates.

[0030] In the present utility model, combined with Figure 4 and Figure 6 As shown, the feeding mechanism of this embodiment includes a lower hopper 12 and a first electric push rod 11. The lower hopper 12 is longitudinally installed on the gantry 1. A lower hole 20 is horizontally penetrated at the bottom end of the lower hopper 12. A mounting hole is provided on the hinge seat 7, and the lower hole 20 is on the same axial line as one of the mounting holes. The first electric push rod 11 is installed at the end of the lower hole 20 away from the mounting hole. A plurality of rotating shaft rods 13 are longitudinally stacked in the lower hopper 12.

[0031] As mentioned above, when using the feeding mechanism provided by the utility model, multiple rotating shaft rods 13 are stacked and installed on one side of the rotation direction of the rotating shaft 9 through the lower hopper 12. When the rotating shaft 9 rotates, the hinge seat 7 in the placement seat 10 passes through the lower hopper 12 in turn. When the mounting hole on the hinge seat 7 and the unloading hole 20 on the lower hopper 12 are on the same axial center line, the rotating shaft 9 stops rotating. At this time, the first electric push rod 11 is started, thereby pushing the rotating shaft rod 13 in the unloading hole 20 outward and allowing one end of the rotating shaft rod 13 to pass through the mounting hole, thereby realizing the automatic assembly of the rotating shaft rod 13 and the hinge seat 7. When the first electric push rod 11 is reset, the rotating shaft rod 13 above the unloading hole 20 automatically falls into the unloading hole 20, which is convenient for the next unloading.

[0032] Further, in order to limit the position of the rotating shaft rod 13, refer to Figure 1As shown, a stopper 14 is installed on the side of the gantry 1 away from the lower hopper 12, and one end of the shaft rod 13 abuts against the stopper 14. The stopper 14 is installed on the side away from the lower hopper 12. When the shaft rod 13 is pushed out of the lower hopper 12 and abuts against the stopper 14, the shaft rod 13 is completely separated from the lower hopper 12, and at this time, the shaft rod 13 is at the same size at both ends of the hinge seat 7.

[0033] In the present utility model, combined with Figure 1 and Figure 5 As shown, the unloading mechanism of this embodiment includes a shift block 3, a rotating seat 5 and a collecting bucket 2, the collecting bucket 2 is arranged below the rotating shaft 9, the rotating seat 5 is installed on the inner side of the gantry 1, a connecting rod 4 connected to the shift block 3 is rotatably installed on the rotating seat 5, a first motor 6 for driving the connecting rod 4 to rotate is installed on one side of the rotating seat 5, and the shift block 3 is arranged above one of the rotating shaft rods 13.

[0034] As mentioned above, when using the unloading mechanism provided by the utility model, the rotating seat 5 in the unloading mechanism provides an installation position for the first motor 6, and at the same time provides a rotation position for the connecting rod 4. The shift block 3 is rotatably installed on the rotating seat 5 through the connecting rod 4. When the welded hinge is under the shift block 3, the first motor 6 is started, driving the connecting rod 4 to rotate on the rotating seat 5, thereby driving the shift block 3 to swing downward, and then allowing the shift block 3 to abut against the rotating shaft rod 13, and move the hinge downward from the placement seat 10. When the downward force of the hinge is greater than the suction force of the magnet 18, the hinge detaches from the placement seat 10 and enters the collection bucket 2. At this time, the shift block 3 is reset, realizing the automatic unloading function of the equipment.

[0035] In the present utility model, combined with Figure 3 As shown, the welding mechanism of this embodiment includes two symmetrically distributed mounting plates 16, and a plurality of welding gun heads 17 are distributed in a circular array on the opposite side of each mounting plate 16. A mounting frame 15 is installed on one side of the gantry 1, and a second electric push rod 19 connected to the mounting frame 15 is installed on the opposite sides of the two mounting plates 16. Each second electric push rod 19 is used to drive the corresponding plurality of welding gun heads 17 to be located in the gap between the rotating shaft rod 13 and the mounting hole.

[0036] As mentioned above, when using the welding mechanism provided by the utility model, the mounting frame 15 in the welding mechanism will provide an installation position for the second electric push rod 19, and at the same time, the two mounting plates 16 are symmetrically installed on both sides of the area where the hinge seat 7 passes through the two electric push rods. When the hinge seat 7 with the rotating shaft rod 13 is between the two mounting plates 16, the second electric push rod 19 is started, driving the two mounting plates 16 to be relatively close, so that the multiple welding gun heads 17 on the mounting plate 16 are located in the gap between the rotating shaft rod 13 and the mounting hole, and then the rotating shaft rod 13 and the hinge seat 7 are welded in multiple directions at the same time through the multiple welding gun heads 17. After the welding is completed, the mounting plate 16 is driven to reset by the second electric push rod 19, so that the welded hinge is away from the welding area.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
