[0032] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-9 The present invention provides a technical solution: a positioning support device for welding civil defense doors, including a base plate 1 and a control system. The top of the base plate 1 is provided with a clamping and flipping assembly for placing the door panel. Above the clamping and flipping assembly are two sets of pressing assemblies for pressing and moving the frame. Below the clamping and flipping assembly is a suction cup assembly for adsorbing the door panel to ensure welding stability.

[0034] A welding robotic arm 2 is installed on one side of the base plate 1 for welding the door frame and skeleton. A camera (not shown in the figure) is fixed at the welding head of the welding robotic arm 2.

[0035] The clamping and flipping assembly includes two sets of support frames 3, which are fixed to the left and right sides of the base plate 1 respectively. A motor 4 is fixed to one side of one set of support frames 3. Both sets of support frames 3 are connected to a connecting shaft (not shown in the figure) by bearings. The motor 4 is fixedly connected to the connecting shaft. A flipping plate 7 is fixed on the two sets of connecting shafts. A placement groove (not shown in the figure) is opened on the flipping plate 7. The placement groove is used to place the door panel. Several support plates 8 are fixed on the placement groove inside the flipping plate 7 to support the door panel. A pressure sensor (not shown in the figure) is connected to each set of support plates 8.

[0036] Several clamps 5 are evenly distributed on the left and right sides of the flip plate 7 for clamping the door panel.

[0037] An air source 6 and an oil tank 31 are placed on the base plate 1.

[0038] The pressing assembly includes a sliding plate 36 and a positioning plate 17. A linear drive is provided between the sliding plate 36 and the flip plate 7, which drives the sliding plate 36 to move on the flip plate 7.

[0039] Two sets of first telescopic rods 9 are fixed to the top of the sliding plate 36. A connecting plate 14 is fixed to the output end of the two sets of first telescopic rods 9. Two sets of through slots are provided on the connecting plate 14. A limit plate 10 is slidably connected inside the through slots. A connecting sleeve 33 is fixed to the outside of the first telescopic rods 9.

[0040] The positioning plate 17 has three sets of limiting grooves 24. The inside of the limiting grooves 24 is used to place the skeleton. Two sets of connecting columns 18 are fixed on the positioning plate 17. Each set of connecting columns 18 corresponds to the first telescopic rod 9. A sliding sleeve 16 is slidably connected to the connecting column 18. Temperature sensors 37 are fixed at the bottom of both sides of the leftmost limiting groove 24 on the positioning plate 17.

[0041] The leftmost limiting groove 24 is deeper than the limiting groove 24 on the other side. A pressing plate 22 is slidably connected inside the leftmost limiting groove 24. Several balls 23 are provided at the bottom of the pressing plate 22. A third telescopic rod 21 is fixed inside the connecting column 18 of the leftmost group. The output end of the third telescopic rod 21 is fixedly connected to the pressing plate 22.

[0042] It should be noted that the initial state of the pressing plate 22 is located at the top of the leftmost limiting groove 24, so that the ball 23 is flush with the top of the other limiting groove 24.

[0043] A second telescopic rod 15 is fixed between the sliding sleeve 16 and the connecting sleeve 33. A central sleeve 11 is fixed to one set of the second telescopic rods 15. The central sleeve 11 is hollow, and first pipes 13 are connected to both sides of the central sleeve 11. A nozzle 12 is connected to each set of first pipes 13. A third valve 38 is connected to each set of first pipes 13. A central pipe 32 is connected to the central sleeve 11, and a three-way valve 34 is connected to the central pipe 32. A second pipe 26 is connected to one side of the three-way valve 34, and the other end of the second pipe 26 is connected to the air source 6. A first valve 27 and a first pump body 25 are connected to the second pipe 26. When the first pump body 25 and the first valve 27 are opened, the gas in the air source 6 is transferred to the central pipe 32 through the second pipe 26, and then sprayed out from the nozzle 12 on the first pipe 13 through the central sleeve 11.

[0044] The other side of the three-way valve 34 is connected to a third pipe 30. The third pipe 30 is connected to a second valve 29 and a second pump body 28. The third pipe 30 is connected to the oil tank 31. When the second pump body 28 and the second valve 29 are opened, the lubricating oil in the oil tank 31 is transferred to the central pipe 32 through the third pipe 30, and then sprayed out from the nozzle 12 on the first pipe 13 through the central sleeve 11.

[0045] The suction cup assembly includes two sets of horizontal plates 35, on which several electromagnetic suction cups 19 are provided. The electromagnetic suction cups 19 adsorb the door panel. Several fourth telescopic rods 20 are fixed below the horizontal plates 35. The output end of the fourth telescopic rods 20 is fixedly connected to the electromagnetic suction cups 19. Activating the fourth telescopic rods 20 can drive the electromagnetic suction cups 19 to move up and down.

[0046] The control system is electrically connected to the pressure sensor, camera, linear drive, and temperature sensor 37. Example

[0047] During welding, the door panel is placed in the placement slot, and the clamp 5 is activated to fix the door panel. After the door panel is in place, the fourth telescopic rod 20 is activated to extend and control the electromagnetic chuck 19 to adhere to the bottom surface of the door panel, ensuring the stability of the door panel.

[0048] When the electromagnetic chuck adheres to the door panel, the fourth telescopic rod 20 is retracted, causing the door panel to come into close contact with the support plate 8 until the pressure sensor detects that the pressure of the door panel on the support plate 8 reaches f, which is taken as the initial pressure value.

[0049] Then, control the first telescopic rod 9 to extend, causing the connecting plate 14 to rise, thereby causing the positioning plate 17 to move away from the door panel via the limiting plate 10 and the connecting column 18. At this time, place the three sets of frames on the far left of the door panel (e.g., Figure 7 As shown, the three sets of limiting grooves 24 are respectively aligned with the three sets of frames. Then, the first telescopic rod 9 is controlled to retract, thereby moving the positioning plate 17 closer to the door panel and inserting the frame into the limiting groove 24. At this time, the linear drive is controlled to move the sliding plate 36 on the flip plate 7 along the length of the door panel, thereby moving the frame on the door panel and moving the frame to the appropriate position on the door panel.

[0050] The two sets of pressing components work synchronously.

[0051] Once the frame is in the correct position, the third telescopic rod 21 extends, causing the pressing plate 22 to press against the frame, ensuring close contact between the leftmost frame and the door panel. It should be noted that while the frame and door panel are in close contact, a distance is maintained between the positioning plate 17 and the door panel to facilitate subsequent welding. After the door panel and frame are positioned, the welding robotic arm 2 is controlled to operate, simultaneously starting the motor 4. The flipping plate 7 rotates the door panel along the axis of the motor 4, allowing the welding robotic arm 2 and the motor 4 to work in tandem for better welding of the door panel and frame. The welding robotic arm 2 welds from one end of the frame to the other until welding is complete; the other side of the frame and door panel is welded later.

[0052] During welding, the door panel is rotated by the flipping plate 7. At this time, the pressure sensor detects the pressure of the door panel on the support plate 8 in real time and transmits it to the control system. It is compared with the initial pressure value f. If the pressure value f does not change during the rotation, it means that the door panel is well fixed. If the pressure value f floats during the rotation, it means that the door panel vibrates during welding. The control system records this situation.

[0053] When welding is completed, the second telescopic rods 15 on both sides are extended, so that the positioning plates 17 move towards each other on the frame until the two sets of positioning plates 17 are close together. Since there are ball bearings 23 under the pressing plate 22, it is easy for the positioning plates 17 to move on the frame. When the positioning plates 17 move, the first pump body 25 and the first valve 27 are opened, and the gas in the air source 6 is pumped into the three-way valve 34 through the second pipe 26. Then it is transmitted from the central pipe 32 to the first pipe 13, and the airflow is sprayed from the nozzle 12 to the welding point to air cool the welding point of the door panel and the frame.

[0054] At the same time, the welding robotic arm 2 is controlled to move along the welding area again, and the camera is activated to take pictures of whether there is a gap at the welding area. The signal is transmitted to the control system, which is equipped with an image recognition unit that can distinguish whether there is a weld seam at the welding area.

[0055] When there are weld seams and the door panel vibrates during welding, it indicates that the vibration is affecting the welding quality. In this case, the fourth telescopic rod 20 is further retracted to enhance the contact between the door panel and the support plate 8. The positioning plate 17 is then moved closer to the door panel to ensure close contact between the frame and the door panel, guaranteeing welding stability during flipping. The welding process between the frame and the door panel is then repeated, with any existing weld seams re-welded to ensure welding quality.

[0056] If there is a weld and the door panel does not vibrate, it indicates that the frame and the door panel are not in close contact. At this time, control the second telescopic rod 15 to work separately, control the positioning plate 17 to move to the position where there is a weld, further control the third telescopic rod 21 to extend, and continue to control the pressing plate 22 to press down on the frame at the weld, so that the frame at the weld is in close contact with the door panel. Then control the welding robot arm 2 to weld, and continue to ensure the welding quality. Example

[0057] Based on Example 1, after the secondary welding is completed, the positioning plate 17 continues to be moved to air cool the weld.

[0058] Specifically, when the positioning plate 17 moves, the two sets of temperature sensors 37 under the positioning plate 17 monitor the temperature of the welding point in real time and transmit it to the control system. Since the temperature after cooling is set to a in the control system, when the temperature is lower than or equal to a, it indicates that the air cooling is qualified. When the temperature is still higher than a after the air cooling is over, it indicates that the cooling effect is not good.

[0059] The second pump body 28 and the second valve 29 are opened to pump the lubricating oil from the oil tank 31 into the three-way valve 34. The third valve 38 on the first pipe 13 on the other side is closed to prevent lubricating oil from being blown into the unwelded area on the other side. The lubricating oil is then sprayed onto the welded area through the nozzle 12 via the first pipe 13 towards the welded area to cool it down.

[0060] After cooling down, the positioning plate 17 is moved to the secondary welding point for air cooling to prevent the weld nodules at the secondary welding point from becoming too large and affecting the heat dissipation effect.

[0061] After the leftmost frame is welded, the first telescopic rod 9 is extended to move the positioning plate 17 away from the door panel. Then, the linear drive is moved to the right to make the leftmost limiting groove 24 on the positioning plate 17 correspond to the second frame.

[0062] The first telescopic rod 9 retracts, causing the leftmost limiting groove 24 to engage with the second frame. Then, the linear drive is controlled to move to the right, causing the remaining two sets of frames to move to the right until they reach the appropriate position (e.g., Figure 8 As shown), the second skeleton is welded by repeating the steps of Example 1.

[0063] After the second frame is welded, repeat the steps described in Example 3 to move the third frame to the far right of the door panel, and then repeat the steps in Example 1 to weld the third frame (e.g. Figure 9 (As shown).

[0064] Through the above steps, a pressing component can move the three sets of frames to different positions on the door panel, distributing the frames one by one on the door panel, replacing manual placement and splicing, saving working time and improving work efficiency.
