[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Reference Figure 1 to Figure 2 A prefabricated building wall panel keel welding device includes an operating panel 1 and a welding mechanism 3. The cross-shaped operating panel 1 is provided with a plurality of rectangular grooves running through the upper and lower parts. The operating panel 1 is provided with a clamping mechanism 2, and the welding mechanism 3 is provided with a cleaning mechanism 4.

[0033] The keel of the prefabricated building wall panel is composed of an outer frame formed by four light steel pipe fittings connected end to end and an inner frame formed by multiple longitudinally distributed and transversely distributed light steel pipe fittings welded together.

[0034] The light steel pipe fittings required for welding the prefabricated building wall panel keel are placed on the top of the operation panel 1, and the outer frame and the inner frame of the prefabricated building wall panel keel are synchronously clamped and fixed by the clamping mechanism 2. The welding mechanism 3 is installed on the external equipment, and the welding mechanism 3 is driven by the external equipment to move up, down, left and right. The welding mechanism 3 is used to perform symmetrical welding up and down, and the welding point is vertically calibrated before welding. The welding point is cleaned by the cleaning mechanism 4.

[0035] Reference Figure 1 The clamping mechanism 2 includes an outer frame clamping assembly 21 for clamping the outer frame and an inner frame clamping assembly 22 for clamping the inner frame. The rectangular grooves on the multiple operation panels 1 are arranged below the welding position of the light steel pipe fittings constituting the outer frame and the inner frame of the assembled building wall panel keel.

[0036] Reference Figure 1 and Figure 3The outer frame clamping assembly 21 includes a clamping fixing plate 211, and the top wall of the cross end of the operating panel surface 1 is fixedly connected with multiple clamping fixing plates 211 at equal intervals. The top wall of the cross end of the operating panel surface 1 is slidably connected with multiple external clamping movable plates 214 corresponding to the clamping fixing plates 211 through a spring 1 (not shown in the figure). The multiple corresponding clamping fixing plates 211 and the external clamping movable plates 214 on the same end of the cross end of the operating panel surface 1 clamp the corresponding light steel pipe fittings constituting the keel outer frame; the top wall of the cross end of the operating panel surface 1 is provided with multiple sliding grooves 212 corresponding to the clamping fixing plates 211 and the external clamping movable plates 214, and the sliding grooves 212 on the same end of the cross end of the operating panel surface 1 are slidably connected with corresponding U-shaped slides 213 through electric sliders.

[0037] Reference Figures 1 to 5 The inner frame clamping assembly 22 includes a rack group 221, and multiple rack groups 221 slidably connected to the bottom wall of the operating panel 1 are fixed on the U-shaped slide 213. Each rack group 221 consists of two symmetrically distributed rack conditions. The bottom wall of the operating panel 1 is rotatably connected to a gear 222 corresponding to the rack conditions; the shaft of the gear 222 rotates and penetrates the operating panel 1, and the top wall of the shaft of the gear 222 is fixedly connected to a cam 223 arranged above the operating panel 1. The two cams 223 corresponding to the same rack group 221 are symmetrically distributed, and the sides of the two corresponding cams 223 symmetrically distributed that are close to each other are each provided with an inner clamping movable plate 224 slidably connected to the top wall of the operating panel 1 through a spring 2 (not shown in the figure), and the corresponding inner clamping movable plates 224 clamp the corresponding light steel pipe fittings constituting the inner frame of the keel.

[0038] When the light steel pipe fitting is placed on the top of the operating panel 1, the U-shaped slide 213 slides on the slide groove 212 driven by the electric slider, and the U-shaped slide 213 approaches the outer clamping movable plate 214 and pushes the outer clamping movable plate 214 to move toward the light steel pipe fitting. The outer clamping movable plate 214 and the corresponding clamping fixed plate 211 clamp the corresponding light steel pipe fitting constituting the outer frame to ensure that it will not be displaced during welding. The clamping fixed plate 211 and the outer clamping movable plate 214 are provided with multiple groups to increase the stability of clamping.

[0039] When the U-shaped slide 213 moves, it synchronously drives the rack set 221 to slide on the bottom wall of the operating panel 1. The movement of the rack set 221 drives the corresponding gear 222 to rotate, and the gear 222 drives the cam 223 to rotate on the operating panel 1. During the rotation process, the cam 223 pushes the inner clamping movable plate 224 to approach the corresponding side wall of the light steel pipe fitting that constitutes the inner frame. When the two symmetrical inner clamping movable plates 224 approach each other, the light steel pipe fitting therebetween is clamped, so as to realize rapid clamping and limiting of the outer frame and the inner frame at the same time, improve the clamping efficiency, and save the time of welding processing.

[0040] Reference Figure 1 and Figure 6 The welding mechanism 3 includes a support platform 1 31 and a support platform 2 35 installed on external equipment. The support platform 1 31 and the support platform 2 35 are relatively distributed up and down. A welding robot 1 32 is installed on the bottom wall of the support platform 1 31, and a welding robot 2 36 is installed on the top wall of the support platform 2 35. The welding mechanism 3 also includes an upper stabilizing component 33 and a lower stabilizing component 34 that cooperate with each other to stabilize the welding position and calibrate the verticality of the light steel pipe fitting.

[0041] Reference Figures 6 to 9 The upper stabilizing component 33 includes a hydraulic rod 331. The hydraulic rod 331 is installed on the bottom wall of the support platform 31 away from the welding robot 32. The bottom wall of the output end of the hydraulic rod 331 is fixedly connected to an inverted U-shaped stabilizing frame 332. The bottom walls of the vertical sections of the inverted U-shaped stabilizing frame 332 have different heights. The side walls of the long vertical sections of the inverted U-shaped stabilizing frame 332 are horizontally slidably connected to a locking slider 333 through an electric slider.

[0042] Reference Figures 6 to 9 The lower stabilizing assembly 34 includes a hydraulic rod 2 341, and a hydraulic rod 2 341 is installed on the top wall of the support platform 2 35 away from the welding robot 2 36. The top wall of the output end of the hydraulic rod 2 341 is fixedly connected to a U-shaped stabilizing frame 342, and the top walls of the vertical sections of the U-shaped stabilizing frame 342 have different heights. The side walls of the long vertical sections of the U-shaped stabilizing frame 342 are horizontally slidably connected to a locking slider 2 343 through an electric slider; slots for the locking slider 1 333 and the locking slider 2 343 to slide are provided inside the long vertical sections of the inverted U-shaped stabilizing frame 332 and the U-shaped stabilizing frame 342, and the locking slider 1 333 is in a convex shape, and the locking slider 2 343 is in a concave shape that matches the locking slider 2 343.

[0043] When the outer frame and the inner frame are clamped, the welding mechanism 3 and the cleaning mechanism 4 are driven by external equipment to move to different welding positions. The external equipment drives the support platform 1 31, the welding robot 1 32 and the upper stabilizing component 33 from top to bottom to approach the light steel pipe fittings, and drives the lower stabilizing component 34, the support platform 2 35 and the welding robot 2 36 from bottom to top through the corresponding rectangular groove of the operating panel 1 and approach the light steel pipe fittings.

[0044] When welding is performed on the four corners and T-shaped welding joints of the outer frame, the support platform 1 31 drives the hydraulic rod 1 331, the inverted U-shaped stabilizing frame 332 and the engaging slider 1 333 to move downward, and the support platform 2 35 drives the hydraulic rod 2 341, the U-shaped stabilizing frame 342 and the engaging slider 2 343 to move upward, the engaging slider 2 343 and the engaging slider 1 333 engage with each other, the U-shaped stabilizing frame 342 and the inverted U-shaped stabilizing frame 332 are parallel to each other, the inverted U-shaped stabilizing frame 332, the U-shaped stabilizing frame 342 and the engaging slider 2 343 and the engaging slider 1 333 are vertically distributed, the U-shaped stabilizing frame 342 and the inverted U-shaped stabilizing frame 332 perform vertical calibration on the four corners or T-shaped welding joints of the outer frame and maintain stability during welding.

[0045] Specifically, one of the light steel pipe fittings is clamped between the two vertical sections of the inverted U-shaped stabilizing frame 332, and the other light steel pipe fitting is clamped between the two corresponding vertical sections of the inverted U-shaped stabilizing frame 332 and the U-shaped stabilizing frame 342. At the same time, the engaging slider 1 333 and the engaging slider 2 343 cooperate to tighten the corresponding pipe ends, thereby achieving vertical calibration.

[0046] When welding is performed on the cross-shaped welding part of the inner frame, the engaging slider 2 343 is driven by the electric slider to enter the slot of the vertical section of the U-shaped stabilizing frame 342, and the engaging slider 1 333 is driven by the electric slider to enter the slot of the vertical section of the inverted U-shaped stabilizing frame 332, and the support platform 1 31 drives the hydraulic rod 1 331, the inverted U-shaped stabilizing frame 332 and the engaging slider 1 333 to move downward, and the support platform 2 35 drives the hydraulic rod 2 341, the U-shaped stabilizing frame 342 and the engaging slider 2 343 to move upward, and the U-shaped stabilizing frame 342 and the inverted U-shaped stabilizing frame 332 are parallel to each other, and the U-shaped stabilizing frame 342 and the inverted U-shaped stabilizing frame 332 clamp the four angles of the cross-shaped welding, and perform vertical calibration and maintain stability during welding.

[0047] Specifically, one of the light steel pipe fittings is clamped between the two vertical sections of the U-shaped stabilizing frame 342 and between the two vertical sections of the inverted U-shaped stabilizing frame 332, and the other light steel pipe fitting and the above-mentioned light steel pipe fitting are distributed in a cross shape. The light steel pipe fitting is clamped from the left and right sides by the U-shaped stabilizing frame 342 and the inverted U-shaped stabilizing frame 332, and the four intersecting corners of the two light steel pipe fittings are attached to the side walls of the vertical sections of the U-shaped stabilizing frame 342 and the inverted U-shaped stabilizing frame 332, thereby achieving vertical calibration.

[0048] During welding, the upper welding robot 32 and the lower welding robot 2 36 synchronously perform symmetrical welding processing on the upper and lower horizontal surfaces of the welding position. After the upper and lower surfaces are welded, the output end of the hydraulic rod 1 331 moves upward and the output end of the hydraulic rod 2 341 moves downward, driving the inverted U-shaped stabilizing frame 332 and the U-shaped stabilizing frame 342 away from the side of the welding position. When the inverted U-shaped stabilizing frame 332 and the U-shaped stabilizing frame 342 no longer block the vertical welding position, the welding robot 1 32 and the welding robot 2 36 respectively perform symmetrical welding synchronously from the left and right sides, so as to achieve simultaneous welding on both sides to balance the welding stress.

[0049] Reference 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 stabilizing frame 332 and the top wall of the short vertical section of the U-shaped stabilizing frame 342 are both driven and rotated by a motor (not shown in the figure) to be connected with the horizontal cleaning brush 41. The brushing surface of the horizontal cleaning brush 41 on the inverted U-shaped stabilizing frame 332 faces downward, and the brushing surface of the horizontal cleaning brush 41 on the U-shaped stabilizing frame 342 faces upward; the bottom wall and the top wall corresponding to the horizontal cleaning brushes 41 on the inverted U-shaped stabilizing frame 332 and the U-shaped stabilizing frame 342 are fixedly connected with a vertical cleaning roller 42. The horizontal cleaning brush 41 is used to clean the horizontal surface of the welding part of the light steel pipe fittings, and the vertical cleaning roller 42 is used to clean the vertical surface of the welding part of the light steel pipe fittings.

[0050] In the process of support platform 1 31 and support platform 2 35 driving the upper stabilizing component 33 and the lower stabilizing component 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 close to the horizontal welding position from the upper and lower directions, the vertical cleaning roller 42 approaches the vertical welding position, and support platform 1 31 and support platform 2 35 stop moving. The horizontal cleaning brush 41 and the vertical cleaning roller 42 are driven by a motor to rotate synchronously. The rotating horizontal cleaning brush 41 and the vertical cleaning roller 42 brush and clean the horizontal and vertical welding positions to clean the oil, rust or moisture on the welding surface of the light steel pipe fittings to avoid welding defects such as welding pores, cracks, slag inclusions, etc.

[0051] It should be noted that when the motor stops driving the horizontal cleaning brush 41 and the vertical cleaning roller 42 to rotate, the horizontal cleaning brush 41 is interlaced with the light steel pipe. When the cleaning is completed and the horizontal cleaning brush 41 does not hinder the movement of the inverted U-shaped stabilizing frame 332 and the U-shaped stabilizing frame 342, the support platform 1 31 and the support platform 2 35 continue to drive the inverted U-shaped stabilizing frame 332 and the U-shaped stabilizing frame 342 to move.

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

[0053] When the outer frame and the inner frame are clamped, the external equipment drives the support platform 1 31, the welding robot 1 32 and the upper stabilizing assembly 33 to move from top to bottom close to the light steel pipe fitting, and drives the lower stabilizing assembly 34, the support platform 2 35 and the welding robot 2 36 to move from bottom to top through the rectangular groove corresponding to the operating panel 1 close to the light steel pipe fitting, 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] Symmetrical welding is performed synchronously by welding robot 1 32 and welding robot 2 36, and the light steel pipe fittings at the welding point are vertically calibrated and supported by U-shaped stabilizing frame 342 and inverted U-shaped stabilizing frame 332 to maintain stability during welding.
