[0002] Welding is a process in which the materials of the workpieces are heated or pressurized (with or without filler materials) to combine the workpieces to form a permanent connection. At present, most of the operations in factories are manual. The front plate of the hopper and the M plate to be welded are clamped and positioned manually, and then butt-welded. This is inefficient and has poor reliability. However, as companies have higher and higher requirements for the quality of welding products, traditional manual welding can no longer fully meet the needs of current corporate development. On the other hand, due to the poor welding working environment, manual operation will cause unstable welding quality, and has high operating requirements for staff, and at the same time, it will cause safety hazards.

[0003] In the prior art, for example, a welding displacement tool with publication number CN210908755U is provided with a fixed shaft used in conjunction with a positioning assembly on a rotating disk, so that the workpiece to be welded is firmly fixed on the rotating disk, and a supporting mechanism for assisting the rotation of the workpiece is provided on one side of the rotating disk, thereby greatly improving the welding accuracy and welding quality of the equipment;

[0004] However, the patent often has the following defects in the process of preparing the composite membrane:

However, as enterprises have higher and higher requirements for the quality of welding products, traditional manual welding can no longer fully meet the needs of current enterprise development;

One clamping can realize fully automated welding of the hopper mechanism, and two workstations can be loaded and unloaded at the same time, so as to achieve efficient production and reduce manpower and material resources, and also avoid the phenomenon of unstable welding quality caused by manual operation. Multiple exhaust pipes are linked by a linkage rod, so as to drive the exhaust pipe to adjust the angle in the sliding groove. During the welding process, the welding slag generated by the welding can be blown away to prevent the welding slag from affecting the welding result, and the exhaust pipe can adjust the angle according to the welding position to improve the chip blowing efficiency, so as to solve the problems raised in the above-mentioned background technology.

An implementation process of the robot welding displacement tooling for the hopper front plate and M plate according to claim 7, characterized in that: The steps include: Step 1: When welding the M-plate, two workpieces of the M-plate are placed on the M-plate mold (3), and the two workpieces are positioned on the M-plate mold (3) using a positioning shaft, and then the crossbeam pressing plate (42) is also positioned using the positioning shaft and presses the two workpieces to be welded, and then the cylinder (41) is used to press them tightly; Step 2: When welding, the other side of the welding is pressed by the upper quick clamp (12) to achieve precise positioning. When welding the front plate of the hopper, the positioning block (132) and the positioning shaft are used to achieve precise positioning. The crossbeam pressure plate (42) and the lower quick clamp (13) are used to clamp and fix the welding workpiece to achieve precise positioning. Step 3: When the welding angle needs to be adjusted, the positioner structure (2) drives the tooling welding platform (1) to rotate through the positioner connecting flange (22) to perform position rotation; Step 4: The control system (7) uses the welding robot (5) as the control core to realize the logical control of the overall production process of the workstation. The control of the welding robot (5) and the information instruction interaction of the welding power supply and other equipment are completed through the communication module (75). At the same time, it has an alarm indication. The button box (73) mainly completes the manual operation during the welding process and notifies whether the workstation is ready or not. Step 5: The air pump (63) delivers the gas to the exhaust pipe (65) through the gas delivery pipe (64), and sprays the gas to the welding position through the nozzle to blow away the welding slag at the welding position.

9. The implementation process of the robot welding displacement tooling for the hopper front plate and M plate according to claim 8 is characterized by: In step five, the adjustment motor (661) drives the driving shaft (662) to rotate, and the driving shaft (662) drives the exhaust pipe (65) to rotate. The multiple exhaust pipes (65) are linked via the linkage rod (664), thereby driving the exhaust pipe (65) to adjust the angle in the sliding groove (663).
