When the push driving member 536 drives the guiding block 533 to drive the pushing rod 535 to push the workpiece out of the positioning mechanism 54, the extended guiding rod 538 can block the next workpiece, so as to prevent the workpiece from being pushed out to fall to the ground when the pushing rod 535 returns. Therefore, the guide rods 538 not only have a guiding function, but also can play a role in blocking the workpiece.
The guide block 533 is driven by the pushing driving element 536 to slide along the guide rail 532, the guide block 533 drives the push rod 535 to horizontally move along the transverse direction above the conveying line 51 through the driving block 534, and the push rod 535 abuts against the side edge of the workpiece so as to push out the workpiece.
The positioning mechanism 54 includes a positioning platform 541, a positioning plate 542, a positioning driving member 543, and a push plate 544. The positioning platform 541 is disposed at an opposite side of the pushing driving element 536, and a top surface of the positioning platform 541 is flush with or slightly lower than the conveying surface of the conveying line 51, so that the pushing rod 535 pushes the workpiece onto the positioning platform 541. A positioning plate 542 is fixed on one side of the positioning platform 541 far from the conveying line 51, a positioning plate 542 is also fixed at one end of the positioning platform 541, a positioning driving member 543 is fixed at the other end of the positioning platform 541, a push plate 544 is arranged at the telescopic end of the positioning driving member 543, a positioning space with a push port is formed on one side of the adjacent two positioning plates 542 and the push plate 544, so that a workpiece can be pushed into the positioning space from the push port, and one side of the workpiece abuts against the positioning plate 542 which is parallel to the push plate 544 relatively. After the positioning driving member 543 drives the push plate 544 to push one end of the workpiece to abut against the positioning plate 542 which is parallel to the push plate 544, the positioning driving member 543 drives the push plate 544 to retract, so that the robot 4 can grasp the positioned workpiece. The positioning platform 541 is provided with a sensor for detecting whether a workpiece exists on the positioning platform 541, so as to determine whether to push the blocked workpiece onto the positioning platform 541.
The finished product output device 6 can adopt a belt type conveying line. However, the conveyor line 51 is not limited to this, and other conveyor lines such as a drum conveyor line may be used.
The invention also provides a welding method of the automatic spot welding equipment applying the storage basket, which comprises the following steps:
the net piece 2 is firstly sleeved in the frame 1, so that the periphery of the net piece 2 is in contact with the bottom edge strip 12 of the frame 1, and meanwhile, the periphery of the net piece 2 cannot slide under the constraint action of the side edge strip 11 of the frame 1. And placing the workpiece formed by the frame 1 and the mesh 2 which are sleeved together at the input end of the conveying line 51 of the semi-finished product input device 5.
If only one set of spot welding machine 3 and robot 4 is provided, the workpiece stops moving when it moves to the stopper mechanism 52. If a workpiece is present on the positioning mechanism 54, the workpiece temporarily rests at the blocking mechanism 52. If no workpiece exists on the positioning mechanism 54, the pushing mechanism 53 pushes the workpiece blocked by the blocking mechanism 52 onto the positioning mechanism 54 for positioning, so that the manipulator 4 can grasp the positioned workpiece and move to the lower welding electrode of the spot welding machine 3, so that the upper welding electrode descends to realize welding. The manipulator 4 drives the workpiece to move to a plurality of spot welding positions, when the workpiece moves to one spot welding position, the upper welding electrode descends to perform spot welding, and after the spot welding is performed around the periphery of the net piece 2, the frame 1 and the net piece 2 are welded together to form the storage basket. And moving the welded storage basket to a finished product output device 6, and conveying the finished product to the next procedure for processing.
When two or more sets of spot welding machines 3 and robots 4 are provided, the workpieces are moved from the input end of the line 51 to the output end thereof, and the priority order of the workpiece assignment is sequentially decreased from the stopper mechanisms 52 at the output end of the line 51 to the stopper mechanisms 52 at the input end. I.e. the work pieces are preferentially distributed to the stop 52 at the output end of the conveyor line 51, then to the adjacent stop 52, and so on, and finally to the stop 52 at the input end of the conveyor line 51. For example, three workpieces are put on the input end (right end in fig. 2) of the conveying line 51, the three workpieces are firstly conveyed to the blocking mechanism 52 at the output end (left end in fig. 2) of the conveying line 51, the blocked workpieces are pushed to the positioning mechanism 54 through the pushing mechanism 53 to be positioned, the other two workpieces depend on the blocking mechanism 52 to wait, and after the workpieces on the positioning mechanism 54 are taken away, the blocked workpieces are pushed to the positioning mechanism 54 through the pushing mechanism 53 to be positioned, and the operation is performed in a circulating manner. And similarly, conveying three workpieces at other stations to perform corresponding action processes. Therefore, workpieces can be orderly pushed into the positioning mechanism 54 of the corresponding station, an automatic production line is formed by the matched welding of the multiple groups of spot welding machines 3 and the manipulator 4, and the production efficiency can be greatly improved.
Any combination of the various embodiments of the present invention should be considered as disclosed in the present invention, unless the inventive concept is contrary to the present invention; within the scope of the technical idea of the invention, any combination of various simple modifications and different embodiments of the technical solution without departing from the inventive idea of the present invention shall fall within the protection scope of the present invention.
