Description

Technical Field

[0001] The invention relates to the technical field of power box manufacturing, and in particular to an intelligent welding tool for a power box body and a use method thereof. Background Art

[0002] The power box, also known as the distribution box or distribution cabinet, is a low-voltage power distribution device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. It is used to reasonably distribute electrical energy, facilitate the opening and closing of the circuit, and has a high level of safety protection, and can intuitively display the conduction status of the circuit.

[0003] The body of the power box is generally made of multiple sheet metal plates welded according to a certain size. This structure is simple and can be welded after cutting, bending, and drilling. Preparation work is required before welding, including checking drawings and technical requirements, checking whether the welding machine is well grounded, and removing dirt on both sides of the welding edge. Flat welding should be used as much as possible during welding. If welding is done in other positions, the welding current should be adjusted to reduce it by 10% compared to the flat welding current. During the welding process, the dimensions should be measured at any time to see if they meet the requirements to prevent the distribution box from deforming. When the weld is long or the structure is assembled, it should be fixed by spot welding in sections and then welded to avoid deformation. After welding the distribution box, the coating should be knocked off, the weld nodules and welding slag should be cleaned to ensure that the weld is smooth and clean.

[0004] Because the welding of the electrical box body is generally right-angle welding, the plate needs to be fixed and clamped during the welding process to avoid displacement and deformation.

[0032] The push plate 35 may have multiple sections, correspondingly connected to each telescopic rod 33 .

[0033] The side of the fixing seat 3 facing the splicing assembly is used to place the second plate 5, and a cooling assembly is arranged at the splicing position of the fixing seat 3 relative to the first plate 4 and the second plate 5.

[0034] like Fig.10 As shown, the cooling assembly includes a rotating drum 70, a motor 71, a pumping device 72 and a refrigeration box 73, wherein the rotating drum 70 is rotatably arranged in the fixed seat 3, the driving end of the motor 71 is connected to the rotating drum 70 for driving the rotating drum 70 to rotate, the refrigeration box 73 is fixed in the fixed seat 3 for producing cooling gas, and the pumping device 72 is respectively connected to the rotating drum 70 and the refrigeration box 73 for conveying the cooling gas in the refrigeration box 73 to the rotating drum 70.

[0035] Furthermore, the rotating drum 70 is a hollow structure and is provided with a rotating shaft 701 and a partition 702 inside. The partition 702 connects the rotating shaft 701 and the inner wall of the rotating drum 70 and divides the internal space of the rotating drum 70 into two parts. The rotating drum 70 is provided with several windows 1 703 relative to one of the spaces, and the rotating drum 70 is provided with several windows 2 704 relative to the other space. The fixed seat 3 cooperates with the window 1 703 and the window 2 704 to form an air port 36, and a thermal sensing module 37 is provided between the air ports 36 for detecting temperature changes during welding.

[0036] It should be noted that: a cover plate 74 is provided at the upper opening of the rotating drum 70, the cover plate 74 is fixed on the fixing seat 3, the motor 3 71 is fixed on the cover plate 74 and the driving end passes through the cover plate 74 and is connected to the rotating shaft 701, and a through hole connected to the pumping device 72 is provided on the cover plate 74, and the pumping device 72 is an air pump but not limited to; like Figures 11-12 As shown, window one 703 is an annular structure. When window one 703 corresponds to the air port 36, the airflow in the drum 70 is in a ring shape to spray cooling airflow to the surroundings. Window two 704 is a circular structure and its area is smaller than the area of ​​the air port 36. When window two 704 corresponds to the air port 36, the airflow in the drum 70 is concentrated at the center of the circle to spray cooling airflow.

[0037] like Fig.13 As shown, the welding mechanism includes an x-axis moving module 81, a y-axis moving module 82 and a welding robot arm 83, wherein the x-axis moving module 81 is arranged on both sides of the clamping mechanism, the y-axis moving module 82 is fixed at the moving end of the x-axis moving module 81, and the welding robot arm 83 is arranged at the moving end of the y-axis moving module 82.

[0038] In actual operation, the x-axis moving module 81 and the y-axis moving module 82 are used to adjust the position of the welding robot arm 83. In one embodiment, the x-axis moving module 81 includes a set of slide rails 811, a gantry 812, a motor 813 and a rack 814. The gantry 812 is slidably matched with the slide rails 811. The motor 813 is respectively fixed on one side of the gantry 812 and a gear is provided on the driving end. The rack 814 is respectively arranged on the slide rails 811 and matched with the gear teeth on the motor 813. When the motor is started, the gear will be driven to drive the gantry 812 to move along the direction of the rack 814; the y-axis moving module 82 adopts but is not limited to the screw motor matching method; the welding robot arm 83 can autonomously adjust the welding port and locate the welding position.

[0039] The specific welding methods are as follows: First, fix the plate 14. Place the plate 14 into the fixing groove 30 manually or by an externally set mechanical arm with the welding end facing outward. According to the thickness of the plate 14, the electric push rod 32 pushes the clamp 31 to one side of the plate 14 to locally limit the position but does not restrict the movement of the plate 14. The moving frame 60 moves to the front side of the plate 14, and the moving block 616 is adjusted to the position of the plate 14. The moving frame 60 continues to move forward. The soft pad 2 618 pushes the plate 14 into the fixing groove 30 to the splicing position. The plate 14 squeezes the push plate 35. The pressure sensing module at the bottom of the fixing groove 30 determines whether the plate 14 is in the correct position according to the detected pressure distribution state. If it is not in the correct position, it is adjusted. After the adjustment is completed, the clamp 31 clamps the plate 14 and the soft pad 2 618 is separated from the surface of the plate 14.

[0040] Specifically, the pressure sensing module detects the pressure from the telescopic rods 33 at different positions. When the plate 14 is in the correct position, a certain number of telescopic rods 33 from bottom to top receive the same thrust from the plate 14, and the number of them is related to the height of the plate 14. If one end of the plate 14 is tilted, the telescopic rods 33 will receive uneven thrust. The pressure information corresponding to each telescopic rod 33 is collected, and the difference between adjacent signals is taken and compared with the set ideal value to determine whether it is within the ideal range. If so, the plate 14 is judged to be in the correct position, otherwise the plate 1 is placed unevenly and needs to be adjusted.

[0041] Furthermore, during adjustment, the cushion 2 618 is separated from the surface of the plate 1 4, and the clamp 31 is away from one end of the surface of the plate 1 4 to eliminate the influence of the over-tightening. The cushion 2 618 pushes the plate 1 4 forward again and pulls it back, and this process is repeated until the plate 1 4 is adjusted to the correct position.

[0042] After the plate 1 4 is fixed, the plate 2 5 is adjusted and limited. The plate 2 5 is placed on one side of the fixed seat 3 manually or by an externally set mechanical arm, the moving frame 60 approaches the plate 2 5, the telescopic frame 603 is squeezed and contracted by the plate 2 5, the pressure sensing chamber 601 determines the specific position of the plate 2 5 according to the detected pressure quantity and position, and the pressure sensing chamber 604 determines whether the plate 2 5 is in the correct position according to the detected position of the movable block 605.

[0043] Specifically, the plate 2 5 pushes the telescopic frame 603 to make the pressure sensing chamber 601 detect the pressure. According to the pressure sensing chamber 601 that detects the pressure signal, the placement position of the plate 2 5 can be determined. The contraction degree of the telescopic frame 603 is related to the pressure. In the process of determining and adjusting the position of the plate 2 5, the moving block 616 moves to the middle of the plate 2 5, and the soft cushion 2 618 is used to provide support for the upper side of the plate 2 5 to prevent the plate 2 5 from tipping over. At the same time, the moving frame 60 controls the telescopic frame 603 to contract to half, and determines whether the plate 2 5 is in the correct position according to the pressure sensing chamber 604 corresponding to the pressure sensing chamber 601 that detects the pressure signal.

[0044] Furthermore, because the telescopic frame 603 is not fully retracted, the plate 25 is in an incompletely compressed state. Generally, when the plate 25 leans against one side of the fixed seat 3, it will be tilted at a certain angle. During the contraction of the telescopic frame 603, the plate 25 gradually stands upright, and the position of the plate 25 to which each movable block 605 is attached moves up, driving the corresponding movable block 605 to move up synchronously.

[0045] If the surface of the plate 2 5 is uneven and the local concave position cannot fit the movable block 605, the movable block 605 cannot move synchronously, and the position of the pressure signal detected by the pressure sensing chamber 604 corresponds to the position of each movable block 605. When the surface of the plate 2 5 is flat, the movable blocks 605 should be continuous and at the same height. When the height of the local movable blocks 605 is inconsistent, the flatness of the surface of the plate 2 5 should be checked.

[0046] Furthermore, if one side of the plate 2 5 is lifted during the limiting process, making the splicing side uneven, the corresponding movable block 605 should move up to a higher height than the other movable blocks 605. At this time, the moving frame 60 retreats and limits the position again. When it is determined that the surface quality of the plate 2 5 meets the standard and is in the correct position, the air pump 2 619 starts to pump air, and the soft cushion 2 618 is adsorbed on the surface of the plate 2 5. The plate 2 5 is moved to the splicing position according to the position of the plate 1 4. After the splicing position is aligned, the moving frame 60 continues to move forward to make the telescopic frame 603 completely retracted. At the same time, the air pump 1 612 pumps air, and the switch valve 610 corresponding to the retracted telescopic frame 603 opens, so that the soft cushion 1 609 is adsorbed on the lower surface of the plate 2 5 to achieve upper and lower limiting.

[0047] After preparation, the welding robot arm 83 locates the welding position for welding. During the welding process, the thermal sensing module 37 determines whether the welding point is centrally cooled or the surrounding area of ​​the welding point is indirectly cooled according to the heat distribution state. If the temperature of the welding point rises abnormally, the window 2 704 is adjusted to correspond to the air port 36, and the cooling airflow is input at the same time to spray the welding point centrally; if the temperature of the welding point is high, the window 1 703 is adjusted to correspond to the air port 36, and the cooling airflow is input at the same time, and the cooling airflow is sprayed around the welding point to indirectly cool the welding point with the help of heat exchange; if the temperature of the welding point is normal, no cooling is required. The judgment limit is set manually.
