Description

TECHNICAL FIELD

[0002] In the manufacturing process of the fabricated box house, a laser welding machine needs to be used to weld the column corner support part of the house, and the column corner support part, also known as a corner column, is a vertical load-bearing component at the corner of the overall frame of the box house. The corner column mainly bears the vertical load transmitted from the roof truss, the floor slab and the wall, and therefore the side wall of the corner column is welded with a load-bearing strut. In order to improve the strength of the corner column in supporting the house structure, a load-bearing strut is welded on the corner column.

[0003] At present, the welding mechanism suitable for welding the corner column on the market generally comprises a clamping structure and a welding structure. In actual use, the clamping structure can clamp the corner column and the load-bearing strut, which can facilitate the laser welding machine to weld the load-bearing strut on the corner column, thereby improving the welding efficiency of the corner column.

[0004] However, the welding mechanism can indeed improve the efficiency of welding the load-bearing strut on the corner column in actual use, but it still has some deficiencies in actual use, such as:

When the load-bearing strut and the corner column are assembled, the verticality of the load-bearing strut and the corner column needs to be detected by manual detection equipment, thereby making the welding method of the load-bearing strut and the corner column complicated and affecting the welding quality of the load-bearing strut and the corner column.

DETAILED DESCRIPTION

[0038] In order to enable the above-mentioned objects, features and advantages of the present application to be more clearly understood, the following further describes the present application with reference to the drawings and specific embodiments.

[0039] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a variety of ways beyond the specific embodiments described herein, and the present application is not limited to the specific embodiments described below.

[0040] Example 1: Please refer to Figures 1-11 As shown in the drawings, the present application provides a technical solution:

[0041] The present application is a kind of based on assembly box room column corner piece welding mechanism, including placement base plate 1 And welding manipulator 2 It is connected on placement base plate 1, Placement base plate 1 It is distributed with support structure 3 Relatively, One of the support structure 3 On rotation has first support frame 7, Another support structure 3 On rotation has second support frame 8, Second support frame 8 Slidingly inserted in the inside of first support frame 7;

[0042] The first support frame 7 is connected to the first support structure 4, and the second support frame 8 and the part opposite to the first support structure 4 are connected to the second support structure 10. The first support structure 4 and the second support structure 10 have the same structure.

[0043] The first support frame 7 and the second support frame 8 can form a frame structure to support the corner components of the prefabricated box-type house, facilitating the welding robot 2 to weld and process the corner components of the house columns.

[0044] The first support structure 4 includes a drive slide 41 parallel to the bottom of the first support frame 7. A movable slide rail 43 and an electric push rod 44 are fixed on the first support frame 7. A connecting rod 45 is fixed to the output end of both the movable slide rail 43 and the electric push rod 44. The connecting rod 45 is fixed to the drive slide 41. A movable seat 42 is fixed to the output end of the drive slide 41. An electric gripper 49 is distributed above the movable seat 42. A support hydraulic cylinder 46 and a telescopic rod 47 are fixed between the movable seat 42 and the electric gripper 49. A dust collection shell 48 is connected to the electric gripper 49.

[0045] The movable slide rail 43 and the electric push rod 44 can drive the electric gripper 49 on the drive slide table 41 to move through the connecting rod 45, which makes it easier for the electric gripper 49 to drive the workpiece to abut against the corner component of the column, so as to realize the welding robot 2 to weld the corner component of the column.

[0046] In actual use, the support hydraulic cylinder 46 can work with the telescopic rod 47 to adjust the position of the electric gripper 49, thereby enabling the electric gripper 49 to drive the workpiece to abut against the corner component of the room column, thus improving the welding accuracy of the corner component of the room column.

[0047] A support plate frame 72 is connected to the first support frame 7. A support plate 82 is connected to the second support frame 8 at the opposite part of the support plate frame 72. An angle column 5 is clamped between the support plate frame 72 and the support plate 82. A support member 6 abuts on the angle column 5. The support member 6 is clamped on the electric gripper 49. An angle sensor 410 is connected to the electric gripper 49. A dust collection shell 48 is distributed at the abutting part of the support member 6 and the angle column 5. The angle sensor 410 is distributed on one side of the support member 6.

[0048] When the corner post 5 is clamped between the support plate frame 72 and the support plate 82, the electric gripper 49 can drive the support 6 to abut against the corner post 5. This makes it easier for the welding robot 2 to weld the support 6 onto the corner post 5. At the same time, the angle sensor 410 can detect the angle between the support 6 and the corner post 5, making it easier for the operator to stably weld the support 6 onto the corner post 5. It should be noted that the welding robot 2 shown in this document is a laser welding robot in the prior art.

[0049] Both the first support frame 7 and the second support frame 8 are U-shaped structures. A rotating column 83 is fixed at one end of the second support frame 8 and the first support frame 7 near the support structure 3. The rotating column 83 is inserted into the support structure 3. Both the second support frame 8 and the first support frame 7 rotate on the support structure 3 through the rotating column 83, which makes it easier for the support member 6 to be welded to the corner column member 5.

[0050] Example 2: Please refer to Figures 1-11 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, in this embodiment, when the welding robot 2 drives the support 6 to weld onto the corner post 5, the vacuum cleaner 9 can drive the air inside the vacuum cleaner housing 48 to be discharged to the outside through the telescopic hose 91. During this process, the inside of the vacuum cleaner housing 48 is in a negative pressure state, which can realize that the smoke and dust generated during the welding of the support 6 and the corner post 5 can be collected inside the vacuum cleaner housing 48.

[0051] A displacement slide 11 is connected to the base plate 1. The moving end of the displacement slide 11 is fixed to the bracket structure 3 connected to the second support frame 8. A vacuum cleaner 9 is fixed on the base plate 1 near the second support frame 8 and the first support frame 7.

[0052] When the support structure 3 slides on the displacement slide table 11, the distance between the second support frame 8 and the first support frame 7 can be adjusted, which enables the second support frame 8 to cooperate with the first support frame 7 to weld corner column parts 5 of different lengths.

[0053] The vacuum cleaner 9 has a retractable hose 91 connected to its storage end, and the retractable hose 91 is connected to the discharge end of the vacuum cleaner housing 48. The retractable hose 91 is elastic.

[0054] When the welding robot 2 drives the support 6 to weld onto the corner post 5, the vacuum cleaner 9 can drive the air inside the vacuum chamber 48 to be discharged to the outside through the telescopic hose 91. During this process, the inside of the vacuum chamber 48 is under negative pressure, which can collect the smoke and dust generated during the welding of the support 6 and the corner post 5 into the inside of the vacuum chamber 48.

[0055] Example 3: Please refer to Figures 1-11 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, in this embodiment, when the second support frame 8 slides on the first support frame 7, the bullseye wheel 822 can abut against the corner post 5. This allows the support plate 82 to drive the bullseye wheel 822 to slide on the corner post 5, thereby enabling the support plate 82 to support the corner post 5 at different positions.

[0056] A drive motor 71 is fixed on the first support frame 7. A rotating column 75 is fixed to the output end of the drive motor 71. A drive screw 73 is fixed on the rotating column 75. A sliding slot 74 is provided on the first support frame 7. A second support frame 8 is connected to the first support frame 7 through the sliding slot 74. The drive screw 73 passes through the first support frame 7 and extends into the sliding slot 74. At the same time, the drive screw 73 is threadedly connected to the second support frame 8. A storage cavity 84 is provided on the second support frame 8. The drive screw 73 passes through the storage cavity 84 and extends into the storage cavity 84.

[0057] When the drive motor 71 drives the drive screw 73 to rotate through the rotating column 75, the drive screw 73 can rotate inside the receiving cavity 84, and the second support frame 8 can slide inside the sliding slot 74. This allows for adjustment of the distance between the second support frame 8 and the first support frame 7, thereby facilitating the stable support of the diagonal column 5 of the second support frame 8 and the first support frame 7.

[0058] A rotary motor 81 is fixed to the bracket structure 3 near the second support frame 8. The output end of the rotary motor 81 passes through the bracket structure 3 and the rotating column 83 and is fixed. The rotary motor 81 drives the second support frame 8 and the first support frame 7 to rotate on the bracket structure 3 through the rotating column 83.

[0059] The output end of the rotary motor 81 can drive the second support frame 8 and the first support frame 7 to rotate on the bracket structure 3 through the rotating column 83, which can realize the adjustment of the welding angle of the welding robot 2 diagonal column 5 and support 6.

[0060] The support plate 82 and the support frame 72 have the same structure. The support plate 82 is connected to the part near the support frame 72 with a bullseye wheel 822. The bullseye wheels 822 are evenly distributed on the support plate 82, and the bullseye wheels 822 abut against the corner post 5.

[0061] When the second support frame 8 slides on the first support frame 7, the bullseye wheel 822 can abut against the corner post 5, which allows the support plate 82 to drive the bullseye wheel 822 to slide on the corner post 5, thus enabling the support plate 82 to support the corner post 5 at different positions.

[0062] A clamping piece 821 slides relative to the support plate 82 and the support frame 72. A slide block 823 is fixed to the lower end of the clamping piece 821. At the same time, a bidirectional hydraulic cylinder 824 is fixed to the bottom surface of the support plate 82. The output end of the bidirectional hydraulic cylinder 824 is fixed to the slide block 823. The output end of the bidirectional hydraulic cylinder 824 drives the clamping piece 821 to clamp the diagonal column 5 through the slide block 823.

[0063] Once the support position of the diagonal column 5 of the support plate 82 is determined, the bidirectional hydraulic cylinder 824 can drive the clamping plate 821 to clamp the diagonal column 5 through the slide block 823, thereby realizing the stable connection of the diagonal column 5 on the support plate 82 and the support frame 72, which makes it easy for the electric gripper 49 to drive the support member 6 to abut against the diagonal column 5.

[0064] Since the welding points of the corner posts must not contain dust during welding, the following structure is proposed to enhance the strength of the load-bearing support rods welded to the corner posts;

[0065] Please see Figures 1-11 As shown, the present invention provides a technical solution that differs from Embodiment 1 in that the movable slide rail 43 has an air extraction pipe 484 fixed inside, a piston rod 487 sliding inside the air extraction pipe 484, the piston rod 487 and the connecting rod 45 are fixed, a piston plate 485 is fixed to the end of the piston rod 487 away from the connecting rod 45, a first one-way valve 486 is connected to the piston plate 485 at equal intervals, an air inlet hose 489 is connected to the end of the air extraction pipe 484 near the connecting rod 45, a second one-way valve 488 is fixed to the end of the air extraction pipe 484 away from the connecting rod 45, an exhaust box 481 is fixed to the end of the air inlet hose 489 away from the air extraction pipe 484, an exhaust port 482 and an electric slide rail 483 are provided on the exhaust box 481, and the fixed end of the electric slide rail 483 is fixed to the dust collection shell 48.

[0066] Before the welding robot 2 moves the support 6 to weld the corner post 5, the connecting rod 45 can drive the piston plate 485 to slide forward inside the suction pipe 484 through the piston rod 487. At this time, external air can enter the suction pipe 484 through the second one-way valve 488. At the same time, the air inside the suction pipe 484 can also enter the exhaust box 481 through the air inlet hose 489. The air inside the exhaust box 481 can also blow through the exhaust port 482 to the part of the support 6 and the corner post 5 that is about to be welded, which can prevent dust from being present at the welding part of the support 6 and the corner post 5.

[0067] When the connecting rod 45 can drive the piston plate 485 to slide in the opposite direction inside the suction pipe 484 through the piston rod 487, the external air cannot enter the suction pipe 484 through the second one-way valve 488. At this time, the air inside the suction pipe 484 can be squeezed by the piston plate 485. During this process, the air inside the suction pipe 484 can pass through the first one-way valve 486, which makes it easier for the piston plate 485 to drive the air inside the suction pipe 484 to be pushed into the air intake hose 489.

[0068] Meanwhile, an electric slide rail 483 is connected to the exhaust box 481. The fixed end of the electric slide rail 483 is fixed to the dust collection shell 48, which allows the position of the exhaust box 481 to be adjusted, making it easier for the exhaust box 481 to blow away the dust at the welding parts of the support member 6 and the corner column member 5. When the exhaust box 481 blows away the dust at the welding parts of the support member 6 and the corner column member 5, the staff starts the vacuum cleaner 9. This allows the dust generated during the welding of the support member 6 and the corner column member 5 to be collected inside the dust collection shell 48, enabling the welding robot 2 to drive the support member 6 to weld onto the corner column member 5, thereby improving the strength of the support member 6 welded onto the corner column member 5.

[0069] Since the exhaust box 481 is connected to the dust collection shell 48, and the dust collection shell 48 is connected to the electric gripper 49, when the electric gripper 49 drives the support member 6 to be welded to the corner post member 5 one by one, when the electric gripper 49 drives the dust collection shell 48 to move, the air discharged from the exhaust box 481 can blow on the support member 6 that has been welded to the corner post member 5, thereby achieving rapid cooling of the weld between the support member 6 and the corner post member 5 and improving the strength of the support member 6 welded to the corner post member 5.

[0070] Working principle: In actual use, the staff first places the corner post 5 on the first support frame 7 and the second support frame 8 between the two clamping pieces 821. When the drive motor 71 drives the drive screw 73 to rotate through the rotating column 75, the drive screw 73 can rotate inside the storage cavity 84, and the second support frame 8 can slide inside the sliding slot 74. This can realize the adjustment of the distance between the second support frame 8 and the first support frame 7.

[0071] When the second support frame 8 slides on the first support frame 7, the bullseye wheel 822 can abut against the corner post 5, which enables the support plate 82 to drive the bullseye wheel 822 to slide on the corner post 5, so that the support plate 82 can support the corner post 5 at different positions.

[0072] Once the support position of the diagonal column 5 of the support plate 82 is determined, the bidirectional hydraulic cylinder 824 can drive the clamping plate 821 to clamp the diagonal column 5 through the slide block 823, thereby realizing the stable connection of the diagonal column 5 on the support plate 82 and the support frame 72, which makes it easy for the electric gripper 49 to drive the support member 6 to abut against the diagonal column 5.

[0073] When the electric gripper 49 drives the support 6 to abut against the corner post 5, the angle sensor 410 can detect the angle between the support 6 and the corner post 5. The angle sensor 410 is connected to an external device, which has a program for analyzing the detection data of the angle sensor 410. The operator can understand the detection status of the angle sensor 410 through the external device, which makes it easier for the operator to stably weld the support 6 to the corner post 5. It should be noted that the welding robot 2 shown in this document is a laser welding robot in the prior art.

[0074] When the welding robot 2 drives the support 6 to weld onto the corner post 5, the vacuum cleaner 9 can drive the air inside the vacuum chamber 48 to be discharged to the outside through the telescopic hose 91. During this process, the inside of the vacuum chamber 48 is under negative pressure, which can collect the smoke and dust generated during the welding of the support 6 and the corner post 5 into the inside of the vacuum chamber 48.

[0075] The output end of the rotary motor 81 can drive the second support frame 8 and the first support frame 7 to rotate on the bracket structure 3 through the rotating column 83. This can realize the adjustment of the welding angle of the diagonal column 5 and the support 6 of the welding robot 2, which facilitates the rapid welding of the diagonal column 5 and the support 6 of the welding robot 2.

[0076] Before the welding robot 2 moves the support 6 to weld the corner post 5, the connecting rod 45 can drive the piston plate 485 to slide inside the suction pipe 484 through the piston rod 487. At this time, external air can enter the suction pipe 484 through the second one-way valve 488. At the same time, the air inside the suction pipe 484 can also enter the exhaust box 481 through the air inlet hose 489. The air inside the exhaust box 481 can also blow through the exhaust port 482 to the part of the support 6 and the corner post 5 that is about to be welded, which can prevent dust from being present at the welding part of the support 6 and the corner post 5.

[0077] Meanwhile, an electric slide rail 483 is connected to the exhaust box 481. The fixed end of the electric slide rail 483 is fixed to the dust collection shell 48, which allows the position of the exhaust box 481 to be adjusted, making it easier for the exhaust box 481 to blow away the dust at the welding parts of the support member 6 and the corner column member 5. When the exhaust box 481 blows away the dust at the welding parts of the support member 6 and the corner column member 5, the staff starts the vacuum cleaner 9 to work. This allows the dust collection shell 48 to collect the dust at the welding parts of the support member 6 and the corner column member 5, so that the welding robot 2 can drive the support member 6 to weld onto the corner column member 5, thereby improving the strength of the support member 6 welded onto the corner column member 5.

[0078] Since the exhaust box 481 is connected to the dust collection shell 48, and the dust collection shell 48 is connected to the electric gripper 49, when the electric gripper 49 drives the support member 6 to be welded to the corner post member 5 one by one, when the electric gripper 49 drives the dust collection shell 48 to move, the air discharged from the exhaust box 481 can blow on the support member 6 that has been welded to the corner post member 5, thereby achieving rapid cooling of the weld between the support member 6 and the corner post member 5 and improving the strength of the support member 6 welded to the corner post member 5.

[0079] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
