Optionally, as shown in fig. 3, the assembly welding line further includes a workpiece conveying line 3, and the workpiece conveying line 3 is electrically connected with the control system 14 for conveying the workpiece 2 to the welding equipment 5. The workpiece conveying line 3 in this embodiment is arranged below the feeding platform 411, so that the space of a production and processing site can be saved, and the equipment layout is more compact. The workpiece conveying line 3 comprises a conveying motor (not shown in the figure) and a conveying belt (not shown in the figure), the conveying motor drives the conveying belt to move, and the conveying belt is provided with a plurality of vacant positions for placing the workpieces 2. The workpiece conveying line 3 can automatically convey the workpiece 2 to be close to the welding equipment 5, and the workpiece 2 is taken down from the workpiece conveying line 3 by a worker and is installed on the chuck 7. The staff no longer need the manual work to transport work piece 2, has saved the manpower, has reduced staff's intensity of labour.
The working process of the invention is as follows:
the workpiece conveyor line 3 transports the flange to the welding device 5. The control system 14 controls the conveying motor to drive the conveying chain 412 to move on the feeding platform 411, and the steel pipes 1 with different codes are placed on the steel pipe placing positions 8 on the conveying chain 412. One end surfaces of the steel pipes 1 are flush, so that the control system 14 controls the transverse driving device to drive the pipe taking part 441 to take the steel pipes 1.
The code scanning detection device 42 recognizes the code on the steel pipe 1 and feeds back the code information to the control system 14, and the control system 14 knows the design length of the steel pipe 1. The length detection device 43 measures the actual length of the steel pipe 1 and feeds back the length data to the control system 14. Since the length of the steel pipe 1, the to-be-processed process and other information are recorded in the steel pipe 1 code, the control system 14 can judge whether the steel pipe 1 code is wrong or not by comparing the design length and the actual length of the steel pipe 1.
If the code is wrong, the control system 14 controls the transportation chain 412 to stop running, and the vertical moving device drives the pipe taking part 441 to move downwards to a height close to the steel pipe 1. The control system 14 controls the transverse moving device to drive the pipe taking members 441 to move according to the actual length of the steel pipes 1, and because the end faces of one end of each of the steel pipes 1 are flush, one pipe taking member 441 only needs to move for a fixed distance, and the other pipe taking member 441 only needs to move for a proper distance under the control of the control system 14 according to the actual length of the steel pipe 1. After the pipe taking members 441 on the two sides hook the two ends of the steel pipe 1, the control system 14 controls the vertical moving device to drive the pipe taking members 441 to move upwards, meanwhile, the sliding driving assembly drives the sliding frame 45 to move to the feeding hole, and at the moment, the steel pipe 1 is located right above the waste material tray 10. The control system 14 controls the transverse moving device to drive the two pipe taking parts 441 to move outwards so as to release the steel pipe 1, and the steel pipe 1 falls into the waste tray 10 under the action of self gravity.
If the code is correct, the steel pipe 1 continues to move along with the conveying chain 412 until reaching the discharge hole. The worker conveys the steel pipe 1 from the conveying chain 412 to the steel pipe bracket 52 at the discharge port, and conveys the flange from the work conveying line 3 to the chuck 7 for chucking. The control system 14 controls the movement driving device to drive the movement frame 512 to move so that the flange abuts on the end of the steel pipe 1 according to the length of the steel pipe 1. The control system 14 controls the first welding robot 531 and the second welding robot 532 to weld the flanges to the ends of the steel pipe 1 according to the encoded information of the steel pipe 1, and processes the steel pipe into a semi-finished product. After the welding is completed, the worker takes the semi-finished product off the steel pipe bracket 52 and the chuck 7 and places the semi-finished product on the first guide plate 63.
Under the non-operating condition, first guide plate 63 and second guide plate 65 all are the state of upwards overturning, and the upper surface of first guide plate 63 is same inclined plane with the upper surface of placing board 62, and the upper surface of second guide plate 65 is same inclined plane with the upper surface of flow distribution plate.
For example, when the steel pipe 1 needs to be classified into four types, the materials are marked as a first type material, a second type material, a third type material and a fourth type material, wherein the first type material is a semi-finished product which needs to be bent, and the second type material, the third type material and the fourth type material are straight pipes.
When the control system 14 judges that the semi-finished product belongs to the first type of material, the first driving device is controlled not to drive the first guide plate 63, the first guide plate 63 keeps an upward turning state, and the semi-finished product rolls from the first guide plate 63 to the transmission chain on the placing plate 62 and is conveyed to the pipe bending process by the conveying assembly 66.
When the control system 14 judges that the material belongs to the second class of material, the first driving device drives the first guide plate 63 to turn downwards, the semi-finished product falls into the third channel 13 from the first channel 11, sequentially passes through the first splitter plate, the second guide plate 65, the second splitter plate, the second guide plate 65 and the third splitter plate, and falls into the material tray 67 arranged below one side, far away from the second splitter plate, of the third splitter plate from the obliquely arranged third splitter plate.
When the control system 14 judges that the material belongs to the third type of material, the first driving device drives the first guide plate 63 to turn downwards, and the semi-finished product falls into the third channel 13 from the first channel 11. The second drive means drives the second deflector 65 between the first and second deflectors to flip down and the material falls out of the second channel 12 between the first and second deflectors into one of the material trays 67.
When the control system 14 judges that the material belongs to the fourth material, the first driving device drives the first guide plate 63 to turn downwards, and the semi-finished product falls into the third channel 13 from the first channel 11. The second driving device drives the second diversion plate 65 between the second diversion plate and the third diversion plate to turn downwards, and the materials roll over from the first diversion plate and the second diversion plate and fall out to another material tray 67 when passing through the second channel 12 between the second diversion plate and the third diversion plate.
