[0003] The current welding process generally involves first fixing the plate with a fixture, then starting the welding mechanism to lower the welding head of the lifting welding device. Each welding head corresponds to a welding point of the welding plate. After the plate is welded, the plate is removed from the fixture, turned over, and installed on the fixture again. When both sides are welded, the plate is removed from the fixture again and installed on the plate waiting to be welded. This process is repeated to complete the welding work. However, this welding workstation can only weld one plate at a time, and the welding process of the next plate can only be carried out after the previous plate is taken out, which makes the welding efficiency of the plate low.

[0020] like Figure 1-10As shown, the high-efficiency steel plate welding workstation provided in this embodiment includes a base 1, a fixed base 2 is provided on the base 1, a working disk 3 is rotatably connected to the fixed base 2, a first driving member 31 for driving the working disk 3 to rotate is provided inside the fixed base 2, an output end of the first driving member 31 is connected to the bottom of the working disk 3, four working bins 32 are provided on the working disk 3, the four working bins 32 are equidistantly arranged around the central axis of the working disk 3, and second driving members 33 are provided on the inner walls of both sides of the four working bins 32, and the output ends of the second driving members 33 are connected There is a clamping assembly 4 for preliminarily positioning the steel plate entering the working bin 32. The clamping assembly 4 includes a first telescopic member 41, a clamping plate 42 connected to the movable end of the first telescopic member 41, and a supporting roller 43 connected to the clamping plate 42. The fixed end of the first telescopic member 41 is connected to the output end of the second driving member 33. The plate entering the working bin 32 is received by the supporting roller 43. The relative extension movement of the two groups of first telescopic members 41 in the same working bin 32 drives the relative movement of the clamping plate 42 to position the steel plate entering the working bin 32. The steel plate in the working bin 32 is clamped to keep the steel plate in a straight state for subsequent welding work. The fixed seat 2 is provided with a first working bin 21, a second working bin 22, a third working bin 23 and a fourth working bin 24 which are equidistantly distributed along the central axis of the fixed seat 2. When the first driving member 31 drives the working disk 3 to rotate once, the four working bins 32 correspond to the first working bin 21, the second working bin 22, the third working bin 23 and the fourth working bin 24 respectively. At the same time, the interiors of the second working bin 22 and the third working bin 23 are both provided with There is an electric permanent magnetic suction cup 25 for positioning the steel plate, and a first position welding arm 11 and a second position welding arm 12 are provided on the base 1, and the first position welding arm 11 and the second position welding arm 12 are respectively arranged opposite to the second station bin 22 and the third station bin 23. After the steel plate is adsorbed and fixed by the electric permanent magnetic suction cup 25, the welding operation is performed by the first position welding arm 11 and the second position welding arm 12 to improve the welding accuracy and welding quality. The first driving member 31 and the second driving member 33 can both adopt devices such as servo motors.

[0021] Among them, an infrared transmitter 13 is provided at a position of the base 1 close to the third workstation bin 23, an infrared receiver 14 is provided on the inner wall of the working bin 32, a controller 15 is connected to one side of the base 1, and the infrared receiver 14 and the second driving member 33 are electrically connected to the controller 15. When the working bin 32 rotates to drive the infrared receiver 14 to rotate synchronously, and the infrared receiver 14 receives the infrared light beam emitted by the infrared transmitter 13, at this time, the infrared receiver will transmit the signal to the controller 15. After receiving the signal from the infrared receiver 14, the controller 15 controls the second driving member 33 located in the third workstation bin 23 to rotate, so as to drive the steel plate in the third workstation bin 23 to flip one side, so as to realize the welding work on the other side of the steel plate.

[0022] Further, such as Figure 6 , 7 As shown, a feeding assembly 5 is also provided on the base 1, and the feeding assembly 5 is opposite to the first workstation bin 21. The feeding assembly 5 includes a loading rack 51 and a third telescopic member 52 connected to the base 1. The loading rack 51 is used for stacking steel plates. The loading rack 51 is provided with a receiving groove 53 for the movable end of the third telescopic member 52 to bend and stretch. The movable end of the third telescopic member 52 is connected with a resistance member 6. When in use, the resistance member 6 is located on the side of the plate away from the working disk 3. When the third telescopic member 52 drives the resistance member 6 to move in the direction of the working disk 3, the resistance member 6 follows the movement of the movable end of the third telescopic member 52 to push the plate into the working bin 32. At this time, under the action of the self-gravity of the stacked plates, when the bottom plate is pushed out, the upper plate falls on the bottom inner wall of the loading rack 51. Furthermore, if Figure 8 As shown, the resistance member 6 includes a connecting column 61 and a lifting column 62 slidably connected to the inside of the connecting column 61. A sloped portion 63 is provided on the side of the lifting column 62 away from the working disk 3, and the lifting column 62 is connected to the connecting column 61 through a spring 64. When the third telescopic frame drives the resistance member 6 to push the plate, the vertical surface of the lifting column 62 conflicts with the side wall of the plate to push the plate out of the loading rack 51. When the third telescopic member 52 drives the resistance member 6 to reset, the sloped portion 63 conflicts with the side wall of the plate, so that the lifting column 62 is compressed and the spring 64 moves downward and enters the connecting column 61, which is convenient for the third telescopic member 52 to drive the resistance member 6 to reset. Further, such as Figure 6 As shown, a photoelectric sensor 7 is provided on the loading rack 51, and the photoelectric sensor 7 and the first driving member 31 are electrically connected to the controller 15. When the plate in the loading rack 51 is pushed into the working bin 32 and clamped by the clamping assembly 4, the photoelectric sensor 7 detects a signal of plate discharge and transmits the signal to the controller 15. The controller 15 controls the first driving member 31 to drive the working disk 3 to rotate a certain angle, so that the working bin 32 with the plate is moved into the second working bin 22 to prepare for welding operation. Furthermore, a plurality of rolling balls 44 are rotatably connected to the support roller 43 to reduce the friction between the plate and the support roller 43, so that when the clamping plate 42 pushes the plate for clamping, the friction between the plate and the support roller 43 is reduced; Going further, Figure 5As shown, the fixing seat 2 is provided with a second telescopic member 26, the movable end of the second telescopic member 26 is connected to the electric permanent magnetic chuck 25, and the second telescopic member 26 is electrically connected to the controller 15, and the clamping plate 42 is provided with a pressure detection unit 45, and the pressure detection unit 45 is electrically connected to the controller 15. When the clamping assembly 4 clamps the plate, the plate will generate a certain pressure on the clamping plate 42. At this time, the pressure detection unit 45 will transmit the detected pressure signal to the controller 15, and the controller 15 controls the second telescopic member 26 to drive the electric permanent magnetic chuck 25 to move upward to adsorb and fix the steel plate; The first telescopic member 41, the second telescopic member 26, and the third telescopic member 52 can all be implemented by a mechanism capable of linear motion, such as an electric push rod and a cylinder; Further, such as Figure 3 As shown, a blanking plate 8 is provided inside the fourth workstation bin 24, and the blanking plate 8 is tilted downward from the direction away from the fourth workstation bin 24. After the steel plate enters the fourth workstation bin 24, the clamping assembly 4 releases the clamping fixation of the steel plate, and the steel plate falls downward onto the blanking plate 8 under the action of its own gravity, and slides out through the blanking plate 8.

[0023] like Figure 1-Figure 10 As shown, the welding method of a high-efficiency steel plate welding workstation provided in this embodiment includes the following steps: S1: Loading, first push the steel plate into the working bin 32 through the feeding assembly 5, and preliminarily clamp the plate through the clamping assembly 4. When the photoelectric sensor 7 detects that a plate passes from below, it transmits a signal to the controller 15. The controller 15 controls the first driving member 31 to drive the working disk 3 to rotate, so that the working bin 32 loaded with the plate moves to the top of the first station bin 21; S2: front welding; after the electric permanent magnetic chuck 25 in the second station bin 22 fixes the plate, the plate is welded by the first position welding arm 11; S3: reverse side welding, after the plate in step S2 moves to the third workstation 23, the infrared rays generated by the infrared transmitter 13 are received by the infrared receiver 14, and the infrared receiver 14 transmits the signal to the controller 15, and the controller 15 controls the second driving member 33 in the third workstation 23 to rotate to turn the plate over; S4: unloading. After the welding is completed, the plate moves to the fourth station bin 24, and the clamping assembly 4 releases its clamping, and the plate falls out through the unloading plate 8.
