[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figures 1 to 2 , an assembly type building wall panel keel welding device, which includes an operation panel surface 1 and a welding mechanism 3. A plurality of vertically penetrating rectangular grooves are formed on the cross-shaped operation panel surface 1. A clamping mechanism 2 is arranged on the operation panel surface 1, and a cleaning mechanism 4 is arranged on the welding mechanism 3.

[0033] The assembly type building wall panel keel is jointly welded and composed of an outer frame formed by connecting four light steel pipe members end to end and an inner frame formed by a plurality of longitudinally distributed and a plurality of transversely distributed light steel pipe members.

[0034] Place the light steel pipe members required for welding the assembly type building wall panel keel on the top of the operation panel surface 1. The outer frame and the inner frame of the assembly type building wall panel keel are synchronously clamped and fixed through the clamping mechanism 2. The welding mechanism 3 is installed on an external device, and the external device drives the welding mechanism 3 to move up, down, left and right. Symmetrical welding is carried out up and down through the welding mechanism 3, and vertical calibration is carried out on the welding position before welding. The welding position is cleaned through the cleaning mechanism 4.

[0035] Refer to Figure 1 , the clamping mechanism 2 includes an outer frame clamping component 21 for clamping the outer frame and an inner frame clamping component 22 for clamping the inner frame. The rectangular grooves on the plurality of operation panel surfaces 1 are arranged below the light steel pipe members to be welded at the outer frame and the inner frame of the assembly type building wall panel keel.

[0036] Refer to Figure 1 and Figure 3, the outer frame clamping assembly 21 includes a clamping fixed plate 211. A plurality of clamping fixed plates 211 are equally spaced and fixedly connected to the top wall of the cross end of the operation board surface 1. The top wall of the cross end of the operation board surface 1 is slidably connected with a plurality of outer clamping movable plates 214 corresponding to the clamping fixed plates 211 through a first spring (not shown in the figure). A plurality of corresponding clamping fixed plates 211 and outer clamping movable plates 214 on the same end of the cross end of the operation board surface 1 clamp the corresponding light steel pipe members that make up the keel outer frame; a plurality of chutes 212 corresponding to the clamping fixed plates 211 and the outer clamping movable plates 214 are provided on the top wall of the cross end of the operation board surface 1. A corresponding U-shaped sliding frame 213 is slidably connected to the chutes 212 on the same end of the cross end of the operation board surface 1 through electric sliders.

[0037] Referring to Figures 1 to 5 , the inner frame clamping assembly 22 includes a rack group 221. A plurality of rack groups 221 slidably connected to the bottom wall of the operation board surface 1 are fixedly arranged on the U-shaped sliding frame 213. Each rack group 221 is composed of two tooth conditions symmetrically distributed. A gear 222 corresponding to each tooth condition is rotatably connected to the bottom wall of the operation board surface 1; the shaft rod of the gear 222 rotatably penetrates the operation board surface 1, and a cam 223 arranged above the operation board surface 1 is fixedly connected to the top wall of the shaft rod of the gear 222. Two cams 223 corresponding to the same rack group 221 are symmetrically distributed. On one side of the two symmetrically distributed and corresponding cams 223 close to each other, an inner clamping movable plate 224 slidably connected to the top wall of the operation board surface 1 through a second spring (not shown in the figure) is provided. The corresponding inner clamping movable plates 224 clamp the corresponding light steel pipe members that make up the keel inner frame.

[0038] After the light steel pipe member is placed on the top of the operation board surface 1, the U-shaped sliding frame 213 slides on the chute 212 driven by the electric slider. The U-shaped sliding frame 213 approaches the outer clamping movable plate 214 and pushes the outer clamping movable plate 214 towards the light steel pipe member. The outer clamping movable plate 214 and the corresponding clamping fixed plate 211 clamp the corresponding light steel pipe members that make up the outer frame, ensuring that they will not be displaced during welding. A plurality of groups of clamping fixed plates 211 and outer clamping movable plates 214 are provided to increase the clamping stability.

[0039] When the U-shaped sliding frame 213 moves, it synchronously drives the rack group 221 to slide on the bottom wall of the operation board surface 1. The movement of the rack group 221 drives the corresponding gear 222 to rotate. The gear 222 drives the cam 223 to rotate on the operation board surface 1. During the rotation of the cam 223, it pushes the inner clamping movable plate 224 towards the side wall of the corresponding light steel pipe member that makes up the inner frame. When the two symmetric inner clamping movable plates 224 approach each other, they clamp the light steel pipe member between them; so as to realize the simultaneous rapid clamping and limiting of the outer frame and the inner frame, improve the clamping efficiency and save the welding processing time.

[0040] Refer to Figure 1 and Figure 6 Figure 6 , the welding mechanism 3 includes a first support platform 31 and a second support platform 35 installed on an external device. The first support platform 31 and the second support platform 35 are distributed relatively up and down. A first welding manipulator 32 is installed on the bottom wall of the first support platform 31, and a second welding manipulator 36 is installed on the top wall of the second support platform 35. The welding mechanism 3 further includes an upper stabilizing assembly 33 and a lower stabilizing assembly 34 that cooperate with each other to stabilize the welding position of the light steel pipe fittings and calibrate the verticality.

[0041] Refer to Figures 6 to 9 Figures 6 to 9 , the upper stabilizing assembly 33 includes a first hydraulic rod 331. The first hydraulic rod 331 is installed on the bottom wall of the first support platform 31 away from the first welding manipulator 32. The bottom wall of the output end of the first hydraulic rod 331 is fixedly connected to an inverted U-shaped stabilizing frame 332. The bottom wall heights of the vertical sections of the inverted U-shaped stabilizing frame 332 are different. A clamping slider 333 is horizontally slidably connected to the side wall of the long vertical section of the inverted U-shaped stabilizing frame 332 through an electric slider.

[0042] Refer to Figures 6 to 9 Figures 6 to 9 , the lower stabilizing assembly 34 includes a second hydraulic rod 341. The second hydraulic rod 341 is installed on the top wall of the second support platform 35 away from the second welding manipulator 36. The top wall of the output end of the second hydraulic rod 341 is fixedly connected to a U-shaped stabilizing frame 342. The top wall heights of the vertical sections of the U-shaped stabilizing frame 342 are different. A clamping slider 343 is horizontally slidably connected to the side wall of the long vertical section of the U-shaped stabilizing frame 342 through an electric slider; slots for the clamping slider 333 and the clamping slider 343 to slide are opened inside the long vertical sections of the inverted U-shaped stabilizing frame 332 and the U-shaped stabilizing frame 342. The clamping slider 333 is in a convex shape, and the clamping slider 343 is in a concave shape adapted to the clamping slider 343.

[0043] After both the outer frame and the inner frame are clamped, the external device drives the welding mechanism 3 and the cleaning mechanism 4 to move for different welding positions. The external device drives the first support platform 31, the first welding manipulator 32, and the upper stabilizing assembly 33 to approach the light steel pipe fittings from top to bottom, and drives the lower stabilizing assembly 34, the second support platform 35, and the second welding manipulator 36 to pass through the corresponding rectangular slot of the operation board surface 1 from bottom to top and approach the light steel pipe fittings.

[0044] When welding the four corners and the T-shaped welding joints of the outer frame, the first support table 31 drives the first hydraulic rod 331, the inverted U-shaped stabilizer 332 and the first engaging slider 333 to move downward, and the second support table 35 drives the second hydraulic rod 341, the U-shaped stabilizer 342 and the second engaging slider 343 to move upward. The second engaging slider 343 engages with the first engaging slider 333, the U-shaped stabilizer 342 is parallel to the inverted U-shaped stabilizer 332, and the inverted U-shaped stabilizer 332, the U-shaped stabilizer 342, the second engaging slider 343 and the first engaging slider 333 are vertically distributed. The U-shaped stabilizer 342 and the inverted U-shaped stabilizer 332 vertically calibrate the four corners or the T-shaped welding joints of the outer frame and maintain the stability during welding.

[0045] Specifically, one light steel pipe fitting is stuck between the two vertical sections of the inverted U-shaped stabilizer 332, and the other light steel pipe fitting is stuck between the corresponding two vertical sections of the inverted U-shaped stabilizer 332 and the U-shaped stabilizer 342. At the same time, the first engaging slider 333 and the second engaging slider 343 cooperate to tightly press against the corresponding pipe fitting ends, thereby achieving vertical calibration.

[0046] When welding the cross-shaped welding joint of the inner frame, the second engaging slider 343 enters the slot in the vertical section of the U-shaped stabilizer 342 driven by the electric slider, and the first engaging slider 333 enters the slot in the vertical section of the inverted U-shaped stabilizer 332 driven by the electric slider. The first support table 31 drives the first hydraulic rod 331, the inverted U-shaped stabilizer 332 and the first engaging slider 333 to move downward, and the second support table 35 drives the second hydraulic rod 341, the U-shaped stabilizer 342 and the second engaging slider 343 to move upward. The U-shaped stabilizer 342 is parallel to the inverted U-shaped stabilizer 332, and the U-shaped stabilizer 342 and the inverted U-shaped stabilizer 332 clamp the four included angles of the cross-shaped welding, and perform vertical calibration and maintain the stability during welding.

[0047] Specifically, one light steel pipe fitting is stuck between the two vertical sections of the U-shaped stabilizer 342 and between the two vertical sections of the inverted U-shaped stabilizer 332, and the other light steel pipe fitting is cross-shaped with the above-mentioned light steel pipe fitting. This light steel pipe fitting is clamped from the left and right sides by the U-shaped stabilizer 342 and the inverted U-shaped stabilizer 332, and the four corners where the two light steel pipe fittings intersect are in contact with the side walls of the vertical sections of the U-shaped stabilizer 342 and the inverted U-shaped stabilizer 332, thereby achieving vertical calibration.

[0048] During welding, the upper welding manipulator 32 and the lower welding manipulator 36 synchronously perform symmetric welding on the upper and lower horizontal planes of the welding position. After the upper and lower surfaces are welded, the output end of the first hydraulic rod 331 moves upward and the output end of the second hydraulic rod 341 moves downward, driving the inverted U-shaped stabilizer 332 and the U-shaped stabilizer 342 away from the side of the welding position. When the inverted U-shaped stabilizer 332 and the U-shaped stabilizer 342 no longer block the vertical welding position, the welding manipulator 32 and the welding manipulator 36 respectively perform symmetric welding synchronously from the left and right sides, realizing simultaneous welding on both sides to balance the welding stress.

[0049] Referring to Figure 6 , the cleaning mechanism 4 includes a horizontal cleaning brush 41. The bottom wall of the short vertical section of the inverted U-shaped stabilizer 332 and the top wall of the short vertical section of the U-shaped stabilizer 342 are both driven and rotatably connected with a horizontal cleaning brush 41 by a motor (not shown in the figure). The brushing surface of the horizontal cleaning brush 41 on the inverted U-shaped stabilizer 332 faces downward, and the brushing surface of the horizontal cleaning brush 41 on the U-shaped stabilizer 342 faces upward; the bottom wall and the top wall corresponding to the horizontal cleaning brushes 41 on the inverted U-shaped stabilizer 332 and the U-shaped stabilizer 342 are both fixedly connected with vertical cleaning rollers 42. The horizontal cleaning brush 41 is used to clean the horizontal plane at the welding joint of the light steel pipe fitting, and the vertical cleaning roller 42 is used to clean the vertical plane at the welding joint of the light steel pipe fitting.

[0050] During the process of the first support platform 31 and the second support platform 35 driving the upper stabilizing assembly 33 and the lower stabilizing assembly 34 to move, the cleaning mechanism 4 gradually approaches the welding position, and the horizontal cleaning brush 41 approaches the horizontal welding position. When the two horizontal cleaning brushes 41 are pressed against the horizontal welding position from the upper and lower directions, the vertical cleaning rollers 42 approach the vertical welding position. The first support platform 31 and the second support platform 35 stop moving, and the horizontal cleaning brush 41 and the vertical cleaning rollers 42 are driven by the motor to rotate synchronously. The rotating horizontal cleaning brush 41 and vertical cleaning rollers 42 brush and clean the horizontal and vertical welding positions to clean the oil stains, rust or moisture on the welding surface of the light steel pipe fitting, avoiding welding defects such as welding pores, cracks and slag inclusions.

[0051] It should be noted that when the motor stops driving the horizontal cleaning brush 41 and the vertical cleaning rollers 42 to rotate, the horizontal cleaning brush 41 intersects with the light steel pipe fitting. After the cleaning is completed and the horizontal cleaning brush 41 does not block the movement of the inverted U-shaped stabilizer 332 and the U-shaped stabilizer 342, the first support platform 31 and the second support platform 35 continue to drive the inverted U-shaped stabilizer 332 and the U-shaped stabilizer 342 to move.

[0052] Referring to Figures 1 - 9, the specific operation steps of this prefabricated building wall panel keel welding device are as follows: Place the light steel pipe fittings required for welding the prefabricated building wall panel keel on the top of the operation panel 1. The electric slider drives the U-shaped sliding frame 213, drives the outer clamping movable plate 214 and the corresponding clamping fixed plate 211 to clamp the light steel pipe fittings corresponding to the outer frame, and at the same time drives the rack group 221 to slide, driving the symmetric inner clamping movable plate 224 to clamp the corresponding light steel pipe fittings.

[0053] After both the outer frame and the inner frame are clamped, the external device drives the support platform 1 31, the welding manipulator 1 32 and the upper stabilizing component 33 to move closer to the light steel pipe fittings from top to bottom, drives the lower stabilizing component 34, the support platform 2 35 and the welding manipulator 2 36 to move closer to the light steel pipe fittings from bottom to top through the corresponding rectangular slots of the operation panel 1, and the motor drives the horizontal cleaning brush 41 and the vertical cleaning roller 42 to rotate to brush and clean the horizontal and vertical welding positions.

[0054] Symmetric welding is carried out synchronously by the welding manipulator 1 32 and the welding manipulator 2 36, and the light steel pipe fittings at the welding position are vertically calibrated and supported by the U-shaped stabilizing frame 342 and the inverted U-shaped stabilizing frame 332 to maintain the stability during welding.

[0055] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
