Description

Technical Field

[0001] The present invention relates to the technical field of welding, and particularly to a welding device and method for prefabricated buildings. Background Art

[0002] A large number of prefabricated steel components are required in prefabricated buildings. These prefabricated steel components may encounter situations such as insufficient length or other welding requirements during on-site construction. Therefore, a welding device is needed.

[0003] A patent with the publication number CN117066798A discloses a steel structure welding device for building construction. When in use, one end of the steel structure to be welded is inserted into the rotating shell body, and the steel structure is pressed and fixed by a pressing mechanism. The fourth telescopic member is used to push the horizontal position of the adjusting movable seat, so that the welding ends of the two steel structures are butted at the bottom of the welding member, which is convenient for accurately detecting the butting condition of the welding ends of the steel structures and ensuring the welding effect of the steel structures.

[0004] However, in the actual application of the above patent, when the welding ends of the two steel structures are not butted neatly, after a prompt is issued by the prompt device, the staff adjusts the butting of the steel structures. That is, it cannot automatically adjust the butting of the welding ends of the steel structures, and the staff needs to keep an eye on the prompt device. This not only increases the burden on the operator but also may introduce errors due to the intervention of human factors, affecting the welding accuracy and efficiency. Summary of the Invention

[0032] Please refer to Figures 1-9, An assembled building welding device, including a chassis 1. On the top of the chassis 1, a support one 101 and a support two 102 are respectively and fixedly connected to the left and right sides. A clamping mechanism is respectively arranged on the support one 101 and the support two 102. The two clamping mechanisms are arranged relatively to clamp and position two components to be welded. A welding device 4 is arranged on the upper part of the support one 101. The support one 101 includes an XZ moving assembly 301 and a YZ moving assembly 302.

A finished product conveying assembly is arranged on the top of the chassis 1. A detection device for detecting the butt joint condition of the welding surface of the component to be welded is arranged on the top of the chassis 1 and below the finished product conveying assembly. The finished product conveying assembly includes two parallel conveyor belts 501. A gap is left between the two conveyor belts 501 to allow the detection device to pass freely. A slag collection mechanism is rotatably arranged between the support one 101 and the support two 102.

[0033] As Figure 2 shown, the XZ moving assembly 301, the YZ moving assembly 302 and the XY moving assembly 303 all include an electric slide rail one and a cylinder. The three electric slide rail ones are respectively installed on the upper part, the middle part of the support one 101 and the upper part of the support two 102. Cylinders are installed on the sliders of the electric slide rail one. The welding device 4 is fixedly connected to the telescopic rod of the cylinder of the YZ moving assembly 302.

[0034] As Figure 2 and Figure 3As shown in the figure, both clamping mechanisms include mounting plates 201. The two mounting plates 201 are respectively fixedly connected to the telescopic rods of the cylinders of the XZ moving assembly 301 and the XY moving assembly 303. A rotating block 202 is rotatably connected to each mounting plate 201. A first clamping plate 203 is rotatably connected to each rotating block 202. A second clamping plate 204 is slidably connected to each rotating block 202. A first motor 205 is installed on each rotating block 202. The output shaft of each first motor 205 is fixedly connected to the first clamping plate 203. A screw drive assembly 206 for driving the second clamping plate 204 to slide is provided on each rotating block 202. When the component to be welded is between the first clamping plate 203 and the second clamping plate 204, the first clamping plate 203 rotates to contact one side of the component to be welded, and then the second clamping plate 204 slides close to the other side of the component to be welded, so as to clamp the component to be welded. A second motor 207 is installed on each mounting plate 201. The output shaft of each second motor 207 is fixedly connected to the rotating block 202.

[0035] As Figure 4 and Figure 5 shown, the finished product conveying assembly further includes a third motor 502. The third motor 502 is installed on the top of the chassis 1 and behind the conveyor belt 501. The output shaft of the third motor 502 is fixedly connected to a worm 503. A worm gear 504 is fixedly connected to the rotating shaft at the rear side of the conveyor belt 501. The worm gear 504 is located in the gap between the two conveyor belts 501. The worm gear 504 meshes with the worm 503. The conveyor belt 501 is driven to rotate by the third motor 502 under the meshing action of the worm 503 and the worm gear 504, so as to convey the component away through the conveyor belt 501.

[0036] As Figure 6 shown, the detection device includes an electric slide rail two 601. The electric slide rail two 601 is installed on the top of the chassis 1 and below the finished product conveying assembly. An electric telescopic rod 602 is slidably connected to the electric slide rail two 601. An electric rotating rod 603 is connected to the telescopic rod of the electric telescopic rod 602. A laser detector 604 is fixedly connected to the electric rotating rod 603. A controller 605 is installed on the upper part of the first bracket 101. The laser detector 604 is electrically connected to the controller 605. The telescopic rod of the electric telescopic rod 602 extends to move the laser detector 604 upward to pass through the gap between the two conveyor belts 501, and then the electric rotating rod 603 drives the laser detector 604 to rotate to change the detection direction, so as to detect the upper welding surface of the component.

[0037] As Figure 7 and Figure 8As shown, the welding slag collection mechanism includes a collection box 701. Both the left and right ends of the collection box 701 are fixedly connected with connecting rods 702. The two connecting rods 702 are respectively rotatably connected to the first support 101 and the second support 102. A fourth motor 703 is installed on the first support 101. A driving wheel 704 is fixedly connected to the output shaft of the fourth motor 703. A driven wheel 705 is fixedly connected to the connecting rod 702 at the left end of the collection box 701. The driven wheel 705 meshes with the driving wheel 704. During welding, the fourth motor 703 drives the connecting rod 702 to rotate under the meshing action of the fourth gear 705 and the third gear 704, thereby driving the collection box 701 to rotate below the welding device 4. Furthermore, the collection box 701 can collect the welding slag generated during the welding process. An opening and closing component is installed on the collection box 701. The opening and closing component is used to open or close the opening of the collection box 701 when needed.

[0038] As Figure 8 and Figure 9 shown, the opening and closing component includes a cloth winding roller 801. The cloth winding roller 801 is rotatably connected to the lower end of the collection box 701. One end of the cloth winding roller 801 is provided with a torsion spring 802. One end of the torsion spring 802 is fixedly connected to the axis of the cloth winding roller 801. The other end of the torsion spring 802 is fixedly connected to the collection box 701. A cloth blocking 803 is wound around the cloth winding roller 801. An electric wire winding roller 805 is installed on the upper end of the collection box 701. A connecting rope 804 is wound around the electric wire winding roller 805. The cloth blocking 803 penetrates through the lower end of the collection box 701. The connecting rope 804 penetrates through the upper end of the collection box 701. The end of the connecting rope 804 away from the electric wire winding roller 805 is fixedly connected to the end of the cloth blocking 803 away from the cloth winding roller 801.

[0039] Working principle: Initially, the torsion spring 802 is in a normal state. The cloth blocking 803 remains wound around the cloth winding roller 801, keeping the opening of the collection box 701 open, and the laser detector 604 is in a vertical state.

[0040] During use, the two components to be welded are respectively placed between the clamping plate 1 (203) and the clamping plate 2 (204) of the two clamping mechanisms. Then, the motor 1 (205) of each clamping mechanism is used to drive the clamping plate 1 (203) to rotate and contact one side of the component to be welded. At the same time, the screw drive assembly 206 is used to drive the clamping plate 2 (204) to slide and contact the other side of the component to be welded, so as to firmly clamp the component to be welded by the clamping plate 1 (204) and the clamping plate 2 (203). After the component to be welded is stably clamped by the clamping mechanism, the cylinders of the XZ movement assembly 301 and the XY movement assembly 303 move the clamping mechanisms connected to them towards each other, so that the welding surfaces of the two components to be welded come into contact. At this time, the laser detector 604 emits laser light. After the laser passes through the gap between the two conveyor belts 501, it scans the contact situation of the two welding surfaces and transmits the detection data to the controller 605 for evaluation. When the detection result shows that the two welding surfaces are not properly butted in the Y-axis direction, the electric slide rail 1 of the XY movement assembly 303 is used to move the cylinder and the clamping mechanism thereon until the two welding surfaces are accurately butted in the Y-axis direction. At this time, the electric slide rail 2 (601) is used to drive the electric telescopic rod 602 to move forward. At the same time, the telescopic rod of the electric telescopic rod 602 extends, so that the electric rotating rod 603 and the laser detector 604 thereon move upward, and the electric rotating rod 603 is used to drive the laser detector 604 to rotate from the vertical state to the horizontal state, so that the laser detector 604 can be aligned with the contact surface of the two welding surfaces in the horizontal direction. Then, the laser detector 604 scans the contact situation of the two welding surfaces again and transmits the detection data to the controller 605 for evaluation. When the detection result shows that the two welding surfaces are not properly butted in the Z-axis direction, the electric slide rail 1 of the XZ movement assembly 301 is used to move the cylinder and the clamping mechanism thereon until the two welding surfaces are accurately butted in the Z-axis direction. After the detection is completed, the electric slide rail 2 (601) is used to drive the electric telescopic rod 602 to move backward and reset, and the telescopic rod of the electric telescopic rod 602 retracts and the electric rotating rod 603 drives the laser detector 604 to rotate backward and reset. After that, the motor 4 (703) drives the connecting rod 702 to drive the collection box 701 to rotate downward between the support 1 (101) and the support 2 (102) under the meshing action of the driving wheel 704 and the driven wheel 705 to collect the welding slag generated during the welding process. Then, the welding device 4 moves in the Y-axis and Z-axis directions by the electric slide rail 1 and the cylinder of the YZ movement assembly 302 to adjust the welding head of the welding device 4 to align with the contact part of the welding surfaces of the two components to be welded. Subsequently, the welding head of the welding device 4 works to weld the two components to be welded. The welding slag generated during the welding process naturally falls into the collection box 701 below by gravity for collection. During the welding process, if the component needs to be flipped for welding, the motor 2 (207) is used to drive the rotating block 202 to rotate, so that the component to be welded clamped by the clamping plate 1 (203) and the clamping plate 2 (204) is flipped.And adjust the position of the welding device 4 through the YZ moving component 302 to realign the components to be welded, so that the components to be welded can be directly flipped and welded by the welding device 4. After welding, the complete component formed by the two components to be welded is still clamped by the two clamping machines. Rotate the electric wire reel 805 to wind up the connecting rope 804, so that the baffle 803 is unfolded in the collection box 701 through the connecting rope 804. During this process, the torsion spring 802 will deform and store elastic potential energy, so that the connecting rope 804 and the baffle 803 remain taut. When the baffle 803 is fully unfolded, drive the connecting rod 702 to drive the collection box 701 to rotate in the reverse direction and reset through the engagement of the motor four 703 with the driving wheel 704 and the driven wheel 705. During this process, the baffle 803 can close the opening of the collection box 701 to prevent the welding slag collected in the collection box 701 from slipping out. Subsequently, release the complete component part clamped by the clamping mechanism on the second bracket 102, and then drive the cylinder and the clamping mechanism on it to move downward close to the conveyor belt 501 through the electric slide rail one of the XZ moving component 301, and then release the complete component clamped by the clamping mechanism onto the conveyor belt 501 below through the clamping mechanism. At this time, drive the conveyor belt 501 to rotate through the engagement of the motor three 502 with the worm 503 and the worm wheel 504, so that the complete component is conveyed from the rear side to the front side through the conveyor belt 501, completing the whole welding process of a batch of components. When it is necessary to clean the welding slag collected in the collection box 701, reverse-rotate the electric wire reel 805 to loosen the connecting rope 804. At the same time, under the elastic action of the torsion spring 802, the cloth winding roller 801 gradually rewinds the baffle 803, reopening the opening of the collection box 701, so that the welding slag collected in the collection box 701 can be cleaned.,

[0041] The present invention also provides a use method applicable to the above-mentioned prefabricated building welding device, which mainly includes the following steps:

[0042] S1. Component clamping and positioning: Stably clamp the components to be welded through the cooperation of the motor one 205 and the lead screw drive assembly 206; Adjust the position of the clamping mechanism through the cylinders of the XZ moving component 301 and the XY moving component 303, so that the welding surfaces of the two components to be welded are in contact, and detect the docking situation of the welding surfaces through the laser detector 604. According to the detection results, adjust the position of the clamping mechanism through the electric slide rail one of the XY moving component 303 and the XZ moving component 301 to ensure accurate docking of the welding surfaces in the Y-axis and Z-axis directions;

[0043] S2. Welding slag collection and welding: Drive the collection box 701 to rotate downward through the motor four 703 to collect the welding slag generated during the welding process; Adjust the position of the welding device 4 through the YZ moving component 302, and weld the two components to be welded through the welding device 4;

[0044] S3. Welding Completion and Component Output: After welding is completed, the connecting rope 804 is wound up by the electric wire reel 805, and the baffle cloth 803 is unfolded to close the opening of the collection box 701, preventing the welding slag from slipping out. The complete component is released onto the conveyor belt 501 by the clamping mechanism, and the complete component is output from the front side through the conveyor belt 501.
