Description

Technical Field

[0001] This invention relates to the technical field of automated welding of large plates, specifically a segmented moving back-heating device and its usage method, and more particularly to a high-precision segmented moving back-heating device and its usage method. Background Technology

[0002] Currently, back-heating after segmented welding mainly relies on manual labor, requiring operators to crawl under the sheet metal and use a heat gun to heat the back of the weld area. This results in slow work efficiency, harsh working conditions, and high safety risks. To address this issue, some automated back-heating devices have emerged in the industry, primarily using powered rollers to transport the sheet metal, thus achieving automatic back-heating. However, existing equipment still has several problems, such as the need for manual gun alignment, sheet metal deviation during transport, and the need for continuous real-time manual adjustment of the heat gun position.

[0003] Therefore, there is an urgent need in the market for methods and devices that can efficiently achieve segmented back-burning, freeing up manpower while efficiently completing segmented back-burning operations. Summary of the Invention

[0004] The purpose of this invention is to provide an improved segmented mobile back-heating device and its usage method. Through improvements in structure and method steps, the automation level of back-heating work is increased, the operation process is stable and reliable, and work efficiency and back-heating quality are improved.

[0005] To achieve the above objectives, the technical solution of the present invention is: a segmented mobile back-heating device, wherein the back-heating device is disposed in the back-heating working area, characterized in that: the back-heating device includes two sets of correspondingly arranged segmented transfer gantry frames and a plurality of support roller devices arranged in the back-heating working area, adjacent support roller devices are parallel to each other, the support roller devices are used to support segmented longitudinal bone workpieces, the two sets of segmented transfer gantry frames can move along the arrangement direction of the support roller devices, a flame back-heating device is provided below the support roller devices, and a plurality of movable heating guns are provided on the flame back-heating device; each segmented transfer gantry includes a ground track and a gantry frame that can move along the ground track, the gantry frame is provided with a transverse transfer trolley corresponding to the number of support roller devices, and each transverse transfer trolley is provided with a liftable longitudinal bone clamp; the longitudinal bone clamps on the two sets of segmented transfer gantry frames are respectively paired up to clamp the two ends of each segmented longitudinal bone workpiece.

[0006] Preferably, the flame back-burning device includes a crossbeam and several transverse moving devices mounted on the crossbeam. The crossbeam moving devices can move along the crossbeam, and each crossbeam moving device is equipped with a heating torch. The heating torch and the crossbeam moving device are connected by a lifting device.

[0007] Furthermore, a laser vision inspection system is installed on the gantry to detect the position of the segmented longitudinal bone workpieces. The transverse transfer trolley can move laterally along the gantry. The longitudinal bone chuck is connected to the transverse transfer trolley through a chuck lifting device. A gantry control system is installed on the gantry.

[0008] Furthermore, the longitudinal bone clamp includes a jaw, and a set of symmetrically arranged elastic clamping elements are provided on both sides of the jaw.

[0009] Furthermore, the back-burning working area has 5-12 parallel support roller devices, and the gantry is equipped with 5-12 transverse transfer trolleys corresponding to the number of support roller devices.

[0010] A method of using a segmented mobile back-heating device, characterized by the following steps: a) Two sets of segmented transfer gantry frames are moved to both sides of the back-heating working area, and the segmented longitudinal bone workpieces are loaded onto the support roller device. The gantry frames then move to both ends of the segmented longitudinal bone workpieces; b) A laser vision inspection system on the gantry frames detects and identifies the segmented longitudinal bone workpieces, and then sends the information to the gantry frame control system; c) According to the position information sent by the gantry frame control system, a transverse transfer trolley moves, aligning the longitudinal bone clamps in pairs with each segmented longitudinal bone workpiece. At both ends of the segmented longitudinal workpiece, two longitudinal chucks simultaneously clamp one segmented longitudinal workpiece, and then position correction is performed; d, the laser vision inspection system inspects the segmented longitudinal workpiece again to obtain the precise position of the segmented longitudinal workpiece, and sends the position information to the flame back-burning device; e, multiple sets of heating torches on the flame back-burning device move to below each corresponding segmented longitudinal workpiece according to the position information of the segmented longitudinal workpiece, and then the heating torches are ignited; f, two sets of masts move synchronously, clamping the segmented longitudinal workpiece and moving it above the heating torches to complete the back-burning operation.

[0011] Preferably, in step c, the corresponding longitudinal clamps on the two masts simultaneously clamp both ends of a segmented longitudinal workpiece.

[0012] Furthermore, in step f, if there are a large number of segmented longitudinal bone workpieces and the back-burning operation is not completed in one go, the torch moves to the next group of segmented longitudinal bone workpieces, and the two sets of masts return to perform the back-burning of the next group of segmented longitudinal bone workpieces.

[0013] Furthermore, in step c, the correction method is as follows: the length of the workpiece in the longitudinal direction is L, the first group of segmented transfer gantry detects a certain longitudinal bone with the transverse coordinate X, and the other group of segmented transfer gantry detects the same longitudinal bone with the transverse coordinate Y. Then, the clamp of one group of segmented transfer gantry moves laterally by a distance |XY|, so that the longitudinal bone and the gantry beam are in a perpendicular state.

[0014] Furthermore, in step e, the coordinates of the longitudinal bone and the thickness of the web plate determine the position of the grill gun. For example, if the coordinate of the longitudinal bone is X and the thickness of the web plate is t, then the optimal grilling effect is achieved when the positions of the two grill guns corresponding to the longitudinal bone are X-0.75t and X+0.75t.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides a segmented, movable back-heating device, which is disposed in the back-heating working area, as detailed below. Figure 1 The difference between this and the existing technology is that: the back-burning device includes two sets of corresponding segmented transfer gantry 3 and several support roller devices 1 arranged in the back-burning working area. The adjacent support roller devices are parallel to each other. The support roller devices are used to support the segmented longitudinal bone workpieces. The two sets of segmented transfer gantry can move along the arrangement direction of the support roller devices. A flame back-burning device 2 is provided below the support roller devices. Several movable torches 61 are provided on the flame back-burning device. Each segmented transfer gantry includes a ground track 7 and a gantry 8 that can move along the ground track. A transverse transfer trolley 10 corresponding to the number of support roller devices is provided on the gantry. Each transverse transfer trolley is provided with a liftable longitudinal bone clamp 12. The longitudinal bone clamps on the two sets of segmented transfer gantry are used one-to-one to clamp the two ends of each segmented longitudinal bone workpiece.

[0023] In operation, two sets of masts work together, clamping each segmented longitudinal workpiece in pairs using the longitudinal rib clamps on the masts and correcting for stability. Then, the flame back-heating device is moved to the corresponding segmented longitudinal workpiece, and the heat gun is ignited to perform the back-heating operation. The two sets of masts move in an orderly manner, allowing the segmented longitudinal workpieces to complete the back-heating process. This structure allows for the back-heating of multiple segmented longitudinal workpieces simultaneously, improving work efficiency, reducing manual labor intensity, and providing precise and controllable back-heating, with a high degree of automation.

[0024] Example 1 This embodiment describes a segmented mobile back-heating device. The back-heating device is set in the back-heating working area and includes two sets of corresponding segmented transfer gantry 3 and several support roller devices 1 arranged in the back-heating working area. Adjacent support roller devices are parallel to each other. The support roller devices are used to support the segmented longitudinal bone workpieces. The two sets of segmented transfer gantry can move along the arrangement direction of the support roller devices. A flame back-heating device 2 is provided below the support roller devices. The flame back-heating device is provided with several movable heating guns. Each segmented transfer gantry includes a ground track 7 and a gantry 8 that can move along the ground track. The gantry is provided with a transverse transfer trolley 10 corresponding to the number of support roller devices. Each transverse transfer trolley is provided with a liftable longitudinal bone clamp 12. The longitudinal bone clamps on the two sets of segmented transfer gantry are used one-to-one to clamp the two ends of each segmented longitudinal bone workpiece.

[0025] Specifically, the flame back-burning device includes a crossbeam 4 and several transverse moving devices 5 mounted on the crossbeam. The crossbeam moving devices can move along the crossbeam. Each crossbeam moving device is equipped with a heating torch 61. The heating torch and the crossbeam moving device are connected by a lifting device 6.

[0026] Furthermore, a laser vision inspection system is installed on the gantry to detect the position of the segmented longitudinal bone workpieces. The transverse transfer trolley can move laterally along the gantry. The longitudinal bone chuck is connected to the transverse transfer trolley 10 via a chuck lifting device 11. A gantry control system is installed on the gantry. The longitudinal bone chuck includes jaws 121, and a set of symmetrically arranged elastic clamping elements 122 are provided on both sides of the jaws.

[0027] Furthermore, the back-burning working area has 5-12 parallel support roller devices, and the gantry is equipped with 5-12 transverse transfer trolleys corresponding to the number of support roller devices. In this embodiment, 7 support roller devices and 7 transverse transfer trolleys are used, and the flame back-burning device is equipped with at least 7 torches.

[0028] Example 2 In this embodiment, a segmented mobile back-heating device is described, which mainly consists of a support roller device, a flame back-heating device, and two sets of segmented transfer gantry frames. The support rollers support the segments, the flame back-heating device heats the segments, and the gantry frames can detect and adjust the position of the board and push the segments to complete the back-heating operation.

[0029] The support rollers effectively support the sheet material. The spacing between the support rollers ensures that the sheet material does not deform while bearing the load; the spacing is generally less than 1000mm × 1000mm. The support rollers are non-powered rollers, and they use rolling friction to reduce resistance during movement.

[0030] The flame back-heating device is installed below the support rollers, with the flame torch pointing upwards to heat the back of the board. The flame back-heating device is equipped with multiple torches, typically half the number of the maximum longitudinal ribs, so that the back-heating operation of the entire segment can be completed in a maximum of two actions.

[0031] Each torch in the flame back-burning device has lateral movement and lifting functions, and the movement in both directions is CNC-controlled axes controlled by servo motors, enabling precise movement.

[0032] The configured two-section transfer gantry can operate independently or move synchronously. Each gantry can move longitudinally and is equipped with multiple sections of chucks. The chucks have lateral and lifting functions, with both lateral movement and lifting controlled by CNC axes and servo motors for precise movement. They also feature a brake mechanism to ensure the position remains unchanged when stopped. The number of chucks can be adjusted according to the section size, but must be greater than two sections.

[0033] The clamps on the segmented transfer gantry can hold the longitudinal bones. The drive is pneumatic or hydraulic, and the clamping is stable and reliable. The clamping device can adopt either centering clamping or single-sided positioning clamping.

[0034] When two sets of gantry frames clamp a longitudinal rib simultaneously with the same pair of clamps, the position of the inclined plate can be corrected, so that the position of the longitudinal rib is parallel to the direction of movement of the gantry frame. Each set of segmented transfer gantry frames is equipped with a laser vision inspection device, which can detect the size of the plate and the position of the longitudinal rib, generate corresponding size and position data, and send the position to the gantry transfer device control system and the flame back-burning device.

[0035] This embodiment describes a method for using a segmented mobile back-heating device, including the following steps: a) Two sets of segmented transfer gantry frames are moved to both sides of the back-heating working area, and the segmented longitudinal bone workpieces are loaded onto the support roller device. The gantry frames move to both ends of the segmented longitudinal bone workpieces; b) The laser vision inspection system on the gantry frames detects and identifies the segmented longitudinal bone workpieces, and then sends the information to the gantry frame control system; c) According to the position information sent by the gantry frame control system, the transverse transfer trolley moves, aligning the longitudinal bone clamps in pairs with each segmented longitudinal bone. At both ends of the bone workpiece, two longitudinal bone clamps simultaneously clamp a segmented longitudinal bone workpiece, and then position correction is performed; d, the laser vision inspection system inspects the segmented longitudinal bone workpiece again to obtain the precise position of the segmented longitudinal bone workpiece, and sends the position information to the flame back-burning device; e, multiple sets of heating torches on the flame back-burning device move to below each corresponding segmented longitudinal bone workpiece according to the position information of the segmented longitudinal bone workpiece, and then the heating torches are ignited; f, two sets of masts move synchronously, clamping the segmented longitudinal bone workpiece and moving it above the heating torches to complete the back-burning operation.

[0036] Specifically, in step a, the gantry moves to both ends of the segmented longitudinal bone workpiece, about 200-500mm away from the edge of the plate; in step b, the laser vision inspection system on the gantry inspects and identifies the segmented longitudinal bone workpiece, and the inspection data includes the position of the longitudinal bone and the thickness of the longitudinal bone web.

[0037] Preferably, in step c, the corresponding longitudinal chucks on the two masts simultaneously clamp both ends of a segmented longitudinal rib workpiece. If the segmented longitudinal rib workpiece is in an inclined position when it arrives, the corresponding longitudinal chucks on both sides can straighten the sheet metal. The straightening method is as follows: the length of the workpiece in the longitudinal rib direction is L. The first set of segmented transfer masts detects a certain longitudinal rib at the transverse coordinate X, and the other set of segmented transfer masts detects the same longitudinal rib at the transverse coordinate Y. Then, the chucks of one set of segmented transfer masts move laterally by a distance |XY|, so that the longitudinal rib is perpendicular to the mast crossbeam.

[0038] Furthermore, in step f, if there are many segmented longitudinal bone workpieces and the back-heating operation is not completed in one go, the heating torch moves to the next group of segmented longitudinal bone workpieces, and the two sets of masts return to perform the back-heating of the next group of segmented longitudinal bone workpieces. In step e, the coordinates of the longitudinal bone and the web thickness determine the position of the heating torch. For example, if the longitudinal bone coordinate is X and the web thickness is t, the best back-heating effect is achieved when the positions of the two heating torches corresponding to the longitudinal bone are X-0.75t and X+0.75t.

[0039] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
