Description

Technical Field

[0001] This utility model relates to the field of workpiece welding technology, and in particular to an automatic welding system for box-type plates. Background Technology

[0002] Dust collector housing panels and other equipment housing panels are generally made using reinforcing ribs or profiled sheets with a frame. These panels have numerous ribs and frames, resulting in long transverse welds and sometimes longitudinal welds. Figure 6 As shown, the overall welding workload for the box panel is substantial. Given the advantages of automated welding, such as uniform and regular weld seams, stable product quality, and improved welding efficiency, current methods primarily consider replacing traditional manual welding with automated welding for mass production of box panels. However, existing automated welding equipment, such as welding robots, has limited range of motion and welding area, while box panels are generally quite long. Current automated welding equipment cannot meet the welding requirements of the box panel's stiffeners and frame. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an automatic welding system for box panels that enables long weld seams and meets the welding requirements of box panels.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an automatic welding system for box panels, including a system frame, a tooling frame for fixing box panels is installed inside the system frame, and a panel positioning mechanism is provided on the tooling frame; a traveling guide device for guiding the movement of the tooling frame is installed on the system frame, and a traveling drive device is provided between the tooling frame and the system frame; transverse welding robots are respectively provided on both sides of the traveling direction of the tooling frame, and a longitudinal welding robot is installed on the system frame above the tooling frame.

[0005] As a preferred technical solution, the traveling guide device includes a traveling track support, on which a plurality of traveling rollers are arranged and installed.

[0006] As a preferred technical solution, the traveling track support is provided with a number of side guide rollers arranged on both sides of the tooling frame.

[0007] As a preferred technical solution, the traveling drive device includes two traveling transmission wheels rotatably mounted on the system frame, and a traveling transmission chain is jointly mounted on the two traveling transmission wheels. The traveling transmission chain is provided with a traveling pusher for pushing the tooling frame to travel; one of the traveling transmission wheels is connected to a traveling drive motor.

[0008] As a preferred technical solution, the system frame is provided with a heating device located below the tooling frame.

[0009] As a preferred technical solution, a dust collection device is provided on the upper part of the system frame.

[0010] As a preferred technical solution, the system frame is provided with a rapping device for rapping the weld position at the end of the tooling frame in the direction of travel.

[0011] Due to the adoption of the above technical solution, the automatic welding system for box panels includes a system frame, within which a tooling frame for fixing the box panels is installed. The tooling frame is equipped with a panel positioning mechanism. A travel guide device for guiding the movement of the tooling frame is installed on the system frame. A travel drive device is provided between the tooling frame and the system frame. Lateral welding robots are respectively installed on both sides of the tooling frame in its travel direction, and a longitudinal welding robot is installed on the system frame above the tooling frame. In use, the box panel is placed on the tooling frame and fixed using the panel positioning mechanism. During the uniform movement of the tooling frame, the lateral welding robots perform welding on the lateral weld seams. Therefore, the lateral welding robots do not require a large range of motion to achieve welding of relatively long lateral weld seams, which is beneficial for meeting the welding requirements of box panels. When longitudinal weld seams exist, the upper longitudinal welding robot can be used to weld them. Since longitudinal weld seams are shorter, the longitudinal welding robot can meet the welding requirements of the longitudinal weld seams within its range of motion. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0021] like Figures 1 to 5 As shown, the automatic welding system for the box panel includes a system frame 1, which serves as the carrier for each component in the system. The system frame 1 can be configured as needed, and its specific structure will not be described in detail here.

[0022] The system frame 1 contains a tooling frame 2 for fixing the housing plate 9. The tooling frame 2 is equipped with a plate positioning mechanism 21. After the housing plate 9 is placed on the tooling frame 2, it is fixed and positioned on the tooling frame 2 by the plate positioning mechanism 21, facilitating accurate welding in the subsequent process. The plate positioning mechanism 21 can be implemented using a spiral clamping structure set at each of the four sides of the housing plate 9. This spiral clamping structure is a commonly used method in the tooling field, and its specific structural principle will not be elaborated here.

[0023] Of course, in actual use, the spiral clamping structures on the two adjacent sides can be left inactive and used only for positioning. After the box plate 9 is placed on the tooling frame 2, only the remaining two spiral clamping structures are clamped to achieve fixation and positioning. Similarly, when it is necessary to release the fixation, only the remaining two spiral clamping structures are clamped to release the fixation.

[0024] In actual use, the tooling frame 2 can be conveyed from the upstream riveting and welding area to the system frame 1, so that the box plate 9 can be fixed and positioned on the tooling frame 2 during upstream riveting and welding processes.

[0025] The system frame 1 is equipped with a travel guide device 3 for guiding the movement of the tooling frame 2, so that the tooling frame 2 moves in a specified direction; and under the positioning of the plate positioning mechanism 21 and the guidance of the travel guide device 3, the transverse weld 91 on the box plate 9 always moves along a fixed route, so that it can be easily and accurately welded by welding equipment.

[0026] The traveling guide device 3 described in this embodiment includes a traveling track support 31, on which a plurality of traveling rollers 32 are arranged and installed. The tooling frame 2 is supported on the traveling rollers 32, and the support points of the traveling rollers 32 together form the support surface for the traveling of the tooling frame 2. The rotatability of the traveling rollers 32 can reduce the impact of resistance on the tooling frame 2, which is conducive to the tooling frame 2 maintaining a uniform speed.

[0027] Furthermore, the travel track support 31 is provided with a number of side guide rollers 33 arranged on both sides of the tooling frame 2 to position the two sides of the tooling frame 2, and also to reduce the resistance by rotating, so as to help the tooling frame 2 maintain a uniform speed.

[0028] A travel drive device 4 is provided between the tooling frame 2 and the system frame 1, and the travel drive device 4 drives the tooling frame 2 to move at a constant speed. In this embodiment, the travel drive device 4 includes two travel transmission wheels 41 rotatably mounted on the system frame 1. A travel transmission chain 42 is mounted on both travel transmission wheels 41, and a travel pusher 43 for propelling the tooling frame 2 is provided on the travel transmission chain 42. One of the travel transmission wheels 41 is connected to a travel drive motor. When the travel drive motor drives the travel transmission wheel 41 to rotate, the travel pusher 43 on the travel transmission chain 42, upon contacting the tooling frame 2, can propel the tooling frame 2 forward.

[0029] Based on the above structural principle, there is no direct connection between the traveling drive device 4 and the tooling frame 2. Therefore, this embodiment can be easily connected with the conveying devices of upstream and downstream processes to achieve the purpose of assembly line operation. In actual installation, multiple traveling pushers 43 can be installed on the traveling transmission chain 42 so that they can quickly generate a pushing effect on the tooling frame 2 after it is conveyed from upstream.

[0030] The tooling frame 2 has horizontal welding robots 11 installed on both sides of its travel direction to perform real-time welding of the horizontal welds 91 on the box plate 9 on the tooling frame 2 as it travels at a constant speed. The system frame 1 is equipped with a vertical welding robot 12 installed above the tooling frame 2 to weld the vertical welds 92 on the box plate 9 when they are present.

[0031] Preferably, the system frame 1 is provided with a heating device 5 located below the tooling frame 2. For the box plate 9 that has been preheated before welding, this can reduce the welding temperature difference and cooling rate, thereby reducing welding residual stress and deformation. The heating device 5 can be implemented using heating pipes or heating plates, etc., and is not limited thereto.

[0032] Preferably, a rapping device 6 for rapping the weld position is provided at the end of the tooling frame 2 in the traveling direction on the system frame 1. The rapping device 6 rapping the weld position releases the stress between metal grains and also reduces residual welding stress. In this embodiment, the rapping device 6 includes a rapping shaft 61 rotatably mounted on the system frame 1. A rapping eccentric hammer 62 is fixedly mounted on the rapping shaft 61. The rapping shaft 61 is connected to a rapping drive motor 63. When the box plate 9 passes the rapping device 6 after welding, the rapping drive motor 63 drives the rapping shaft 61 to rotate, and the rapping eccentric hammer 62 strikes the weld position on the box plate 9 at high frequency to achieve the rapping effect. In this embodiment, the rapping device 6 is mainly used for rapping the transverse weld 91. After all welds are completed, the box plate 9 can stop at the end of the traveling direction or stop after exiting the system frame 1 position. The longitudinal weld 92 on it can be rapped manually.

[0033] The upper part of the system frame 1 is equipped with a dust collection device 7 to collect the fumes generated during the welding process. Conventionally, the dust collection device 7 includes a dust collection hood installed on the upper part of the system frame 1, and the dust collection hood is connected to a negative pressure fan.

[0034] In this embodiment, during use, the horizontal welding robot 11 and the vertical welding robot 12 pre-scan and set the welding program according to the welding path and weld condition, and as follows: Figure 2 As shown, the robot is in its initial position before welding begins. When the tooling frame 2, which holds the box plate 9, reaches the designated welding starting point, the signal controls the transverse welding robot 11 and the longitudinal welding robot 12 to automatically weld the weld seam according to the set program, such as... Figure 3 As shown.

[0035] During the welding process, the welding positions of the transverse welding robot 11 and the longitudinal welding robot 12 are preferably located at a relatively far distance. For example... Figure 3As shown, when the transverse weld 91 on the right side of the travel direction is welded by the corresponding transverse welding robot 11, the longitudinal weld 92, which is close to the welding start point of the transverse weld 91, is welded by the corresponding longitudinal welding robot 12 starting from the left side of the travel direction. Similarly, the longitudinal weld 92, which is far from the welding start point of the transverse weld 91, is welded by the corresponding longitudinal welding robot 12 starting from the right side. After the tooling frame 2 has traveled a certain distance, as... Figure 4 As shown, the shorter longitudinal weld 92 is welded first, and then the transverse weld 91 on the left side of the travel direction begins to be welded by the corresponding transverse welding robot 11. When welding this left-side transverse weld 91, if there are other longitudinal welds 92, they are similarly started from a position that is always far away from the welding point of the transverse welding robot 11 during the welding process. Figure 4 As shown, by simultaneously welding at locations far apart, the weld has more room for free shrinkage after welding, which can also reduce residual welding stress.

[0036] In this embodiment, the box plate 9 is placed on the tooling frame 2 and fixed using the plate positioning mechanism 21. During its movement, it is guided by the traveling guide device 3. As the tooling frame 2 is driven to move at a constant speed, the transverse welding robot 11 welds the transverse weld seam 91. Therefore, the transverse welding robot 11 does not require a large range of motion to weld the relatively long transverse weld seam 91, which is beneficial for meeting the welding requirements of the box plate 9. When there is a longitudinal weld seam 92, the upper longitudinal welding robot 12 can be used for welding. Since the longitudinal weld seam 92 is relatively short and the box plate 9 moves at a slower speed, the longitudinal welding robot 12 can meet the welding requirements of the longitudinal weld seam 92 within its range of motion. Accordingly, the longitudinal welding robot 12 can be implemented using an existing multi-arm welding robot or a welding device with three-dimensional motion control; no limitation is made here. In summary, the box plate 9 achieves automatic welding by relying on the assembly line transport of the tooling frame 2, significantly reducing human intervention and improving welding efficiency.
