[0015] In one embodiment, the controller is communicatively connected to the conveying mechanism and is used to control the speed of the conveying mechanism when transporting the workpiece to be back-fired past the back-firing assembly.

[0016] In one embodiment, the vision sensor is arranged at the outer end of the back-firing assembly at the end to detect the position of the reinforcing beam at the end of the workpiece to be back-fired and obtain the back-firing position signal.

[0038] Although the present invention can be easily embodied in different forms of embodiments, only some specific embodiments are shown in the drawings and will be described in detail in this specification. At the same time, it can be understood that this specification should be regarded as a demonstration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0039] Therefore, a feature pointed out in this specification is used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to show a possible system design, these features can also be used in other combinations not specifically described. Therefore, unless otherwise stated, the described combination is not intended to be limiting.

[0040] In the embodiments shown in the drawings, the indication of directions (such as up, down, left, right, front and back) is used to explain that the structures and movements of various elements of the present invention are not absolute but relative. When these elements are in the positions shown in the drawings, these explanations are appropriate. If the descriptions of the positions of these elements change, then the indications of these directions also change accordingly.

[0041] Referring to Figure 1 , the present invention provides a back-burning device, which is applicable to the back-burning of ship structural parts during the shipbuilding process.

[0042] Back burning refers to performing hot work on the back of the weld.

[0043] The back burning device includes a longitudinally extending track 11, multiple groups of back burning components 12 arranged at intervals in the transverse direction, a conveying mechanism 13, a vision sensor 14, and a controller. By moving the workpiece to be back burned 2 through the conveying mechanism 13, collecting information through the vision sensor 14, and controlling the actions of the back burning components 12 by the controller, back burning is achieved in a way that the moving torch 123 for back burning hardly moves, improving efficiency and the quality of back burning.

[0044] Among them, the workpiece to be back burned 2 can be any structure that makes up the hull, such as a deck. The following takes the deck as an example to illustrate the back burning device.

[0045] The deck includes a plate body 21 and strengthening beams 22 arranged in parallel and at intervals on the plate body 21. The strengthening beams 22 extend along the width direction of the plate body 21, and multiple strengthening beams 22 are arranged at intervals along the length direction of the plate body 21.

[0046] The track 11 extends longitudinally. For the convenience of description, the extending direction of the track 11 is defined as the longitudinal direction, and the direction in the horizontal plane and perpendicular to the longitudinal direction is the transverse direction.

[0047] The track 11 can be arranged on the ground or underground. Loading stations and unloading stations are respectively provided at the longitudinal two ends of the track 11.

[0048] In this embodiment, the number of tracks 11 is two, arranged at intervals in the transverse direction.

[0049] The conveying mechanism 13 can move along the track 11 and pass by the back burning components 12. Among them, the conveying mechanism 13 can move along the track 11 to the loading station for loading. After loading, the conveying mechanism 13 moves and passes by the back burning components 12, and back burning is performed during the movement. The conveying mechanism 13 can also move to the unloading station for unloading, unloading the workpiece 2 to be back burned after back burning to the unloading station. That is, the conveying mechanism 13 carries the workpiece 2 to be back burned through the back burning components 12, and the back burning components 12 perform back burning on the moving workpiece 2 to be back burned.

[0050] The conveying mechanism 13 has a supporting surface for supporting the workpiece 2 to be back burned with a length extending in the transverse direction. The supporting surface extends upward beyond the top of the back burning components 12. Specifically, it means that the height of the conveying mechanism 13 is relatively high, capable of being higher than the back burning components 12 upward, so that the workpiece 2 to be back burned is located above the back burning components 12.

[0051] Specifically, the conveying mechanism 13 straddles the two tracks 11 and moves along the tracks 11. In this embodiment, the conveying mechanism 13 is a ground rail trolley.

[0052] A plurality of back-firing assemblies 12 are arranged at intervals in the transverse direction. In this embodiment, there are three back-firing assemblies 12, and there is a track 11 between any two adjacent back-firing assemblies 12, that is, back-firing assemblies 12 are provided on both opposite sides of each track 11, so that the conveying mechanism 13 can pass through the back-firing assemblies 12.

[0053] Combined Figure 2 with Figure 3 , the back-firing assembly 12 includes a plurality of torches 123 arranged at intervals in the transverse direction. The torches 123 are used for back-firing the workpiece to be back-fired 2. The number of torches 123 of the back-firing assembly 12 in the middle is more than that of the back-firing assembly 12 at the end. In this embodiment, the back-firing assembly 12 in the middle includes nine torches 123, and the back-firing assembly 12 at the end includes six torches 123. In other embodiments, the number of torches 123 of each group of back-firing assemblies 12 can be set according to actual needs.

[0054] Among them, the back-firing assembly 12 includes a base 121 and a cross beam 122 arranged on the base 121 and extending in the transverse direction. The base 121 is arranged on the ground on both sides of the track 11. The base 121 includes two struts arranged at intervals in the transverse direction. The struts extend vertically.

[0055] The back-firing assembly 12 includes a lifting power member 124. The lifting power member 124 is used to drive the cross beam 122 to lift relative to the base 121. Specifically, the lifting power member 124 includes a connecting rod extending in the transverse direction and a motor for driving the connecting rod to lift. The connecting rod is slidably connected to both struts, and the motor drives the connecting rod to lift. In this embodiment, the number of motors is two, and the two motors are respectively arranged corresponding to the two columns. The cross beam 122 is connected to the connecting rod and thus lifts.

[0056] The lifting power member 124 is communicatively connected to the controller to receive the control of the controller to rise to a safe height or descend below the safe height.

[0057] A plurality of torches 123 are arranged at intervals in the transverse direction on the cross beam 122. The torches 123 can be laterally translated along the cross beam 122 to adjust the distance between any two adjacent torches 123. Since the intervals between adjacent stiffening beams 22 of decks of different sizes are different, by adjusting the distance between adjacent torches 123, the back-firing assembly 12 can be adapted to the back-firing of decks of different sizes.

[0058] The back-firing assembly 12 includes a locking member 125, and the locking member 125 is used to lock the torch 123 and the cross beam 122.

[0059] Exemplarily, a plurality of sleeving members are sleeved on the outer periphery of the cross beam 122. The sleeving members can move along the cross beam 122, and the torch 123 is arranged on the sleeving members. The locking member 125 is arranged at the bottom of the sleeved design and passes upward through the bottom wall of the sleeving member. The locking member 125 is screwed to the bottom wall of the sleeving member. The locking member 125 can be rotated to raise or lower its top to abut against the bottom of the cross beam 122 or rotated away from the cross beam 122 so that the sleeving member can move.

[0060] In this embodiment, the cross section of the cross beam 122 can be square. The cross section of the sleeving member can also be square. Or the sleeving member includes a U-shaped main body and two flanges arranged at the opening of the main body.

[0061] The distance between two adjacent torches 123 is pre-adjusted according to the size of the piece to be back-fired 2.

[0062] Each torch 123 can be lifted and lowered relative to the cross beam 122. Specifically, the torch 123 is lifted and lowered by a lifting drive member 126. In this embodiment, the lifting drive member 126 includes a motor and a lead screw. The motor is specifically arranged on the top of the sleeving member, and the motor is arranged on the cross beam 122. The lead screw extends vertically, and the lead screw is connected to the output shaft of the motor. The torch 123 is connected to the lead screw. The motor drives the lead screw to rotate clockwise or counterclockwise, so as to lift or lower the torch 123, and further adjust the height distance between the gun head and the piece to be back-fired 2.

[0063] Specifically, the torch 123 is connected to the lead screw through a transition rod. The transition rod extends horizontally. The two gun heads are arranged at both ends of the transition rod along the horizontal direction.

[0064] The torch 123 includes an ignition sensor and a gun head. The gun head can spray flames outward. The ignition sensor is used to detect whether there is a piece to be back-fired 2. The ignition sensor is communicatively connected to the gun head and is used to control the start and stop of the gun head. Specifically, after the ignition sensor detects the piece to be back-fired 2, it controls the gun head to start, that is, to ignite. When the ignition sensor does not detect the piece to be back-fired 2 or detects that the piece to be back-fired 2 has moved away, it controls the gun head to stop working, that is, to extinguish. In this embodiment, each torch 123 includes two gun heads arranged at intervals along the horizontal direction. The two gun heads are inclined towards each other and both face the location of the reinforcing beam.

[0065] The back-firing assembly 12 includes a distance sensor 127 for detecting the vertical distance between the gun head of the torch 123 and the piece to be back-fired 2. Specifically, the distance sensor 127 is at the same height as the gun head. Along the horizontal direction, the distance sensor 127 is located between the two gun heads. Along the longitudinal direction, the distance sensor 127 is arranged at an interval from the gun head, and the distance sensor 127 is arranged upstream of the gun head, that is, the piece to be back-fired first passes through the distance sensor 127 and then passes through the gun head.

[0066] The controller can control the lifting of the torch 123 according to the distance detected by the distance sensor 127, thereby adjusting the distance. Specifically, the controller is communicatively connected to the motor of the lifting drive member 126.

[0067] Further, the back burning assembly 12 further includes a lateral moving power member 128. That is, the back burning assembly 12 includes a base 121, a cross beam 122 disposed on the base 121 and extending laterally, and a lateral moving power member 128. The lateral moving power member 128 is used to drive the cross beam 122 to move laterally relative to the base 121. The lateral moving power member 128 is communicatively connected to the controller and is used to receive the control signal of the controller to drive the cross beam 122 to move laterally. By the movement of the cross beam 122, the torch 123 is aligned with the area to be back burned on the workpiece 2 to be back burned. Exemplarily, when the torch 123 is aligned with the stiffening beam 22 of the deck, the torch 123 can be aligned with the back side of the weld between the stiffening beam 22 and the plate body 21.

[0068] Specifically, the lateral moving power member 128 includes a lead screw and a motor for driving the lead screw to rotate. The lead screw extends laterally and is disposed on the connecting rod of the lifting power member 124. Specifically, a slide rail is provided at the top of the connecting rod, and a nut is connected to the lead screw of the lateral moving power member 128. The nut is slidably engaged with the slide rail, and the nut is fixed to the bottom of the cross beam. Therefore, when the lead screw rotates to drive the nut to move along the slide rail, the cross beam 122 also moves laterally accordingly.

[0069] The vision sensor 14 is disposed above one of the back burning assemblies 12 for collecting the back burning position information of the workpiece 2 to be back burned.

[0070] Specifically, the vision sensor 14 is disposed at the outer end of the back burning assembly 12 at the end for detecting the position of the stiffening beam 22 at the end of the workpiece 2 to be back burned to obtain the back burning position signal. Since the distance between two adjacent stiffening beams 22 in a deck of a fixed size is a fixed value, therefore, by only obtaining the position of the first stiffening beam 22 through the vision sensor 14, all the back burning position information on the deck can be determined, thereby realizing the positioning of the torch 123.

[0071] The back burning device includes a column and a support rod disposed at the top of the column and extending laterally. The column is disposed outside the back burning assembly 12 at the end, as Figure 1 shown. The support rod is located above the back burning assembly 12, and the vision sensor 14 is disposed at the bottom of the support rod.

[0072] Preferably, the vision sensor 14 is disposed at a certain distance from the column on the support rod to ensure that the vision sensor 14 can meet the detection of most sizes of the workpiece 2 to be back burned, so that the distance between the vision sensor 14 and the first stiffening beam 22 on the workpiece 2 to be back burned is relatively close, improving the detection accuracy.

[0073] Exemplarily, the vision sensor 14 may take the center of the column as the origin and detect the longitudinal coordinates of the first reinforcing beam 22 located at the end (or detect the distance between the reinforcing beam 22 and the origin). After the controller obtains the back-burning position signal, the controller controls the transverse driving member 128 to start, so that the center of the torch 123 located at the end moves to the longitudinal coordinates of the reinforcing beam 22.

[0074] The controller is communicatively connected to the vision sensor 14 and is configured to receive the back-burning position information and output a control signal based on the back-burning position information. The controller is communicatively connected to the back-burning assembly 12 and is configured to adjust the position of the torch 123 relative to the workpiece 2 to be back-burned according to the control signal.

[0075] The controller is communicatively connected to the conveying mechanism 13 and is configured to control the speed of the conveying mechanism 13 when transporting the workpiece 2 to be back-burned through the back-burning assembly 12, so that the workpiece 2 to be back-burned is back-burned during the movement. The controller controls the conveying mechanism 13 to pass through the back-burning assembly 12 at different speeds according to the thickness of the workpiece 2 to be back-burned. Generally, the greater the thickness of the workpiece 2 to be back-burned, the slower the speed, so that the workpiece 2 to be back-burned is back-burned for a longer time.

[0076] The present invention also provides a back-burning method, which uses the above-mentioned back-burning device. The back-burning method includes the following steps:

[0077] S1. Load the workpiece 2 to be back-burned onto the conveying mechanism 13, so that the length of the workpiece 2 to be back-burned extends horizontally.

[0078] Among them, the conveying mechanism 13 moves to the loading station, that is, one end of the track 11, and then loads the workpiece 2 to be back-burned onto the conveying mechanism 13.

[0079] S2. The conveying mechanism 13 moves along the track 11 to move the workpiece 2 to be back-burned to the back-burning assembly 12.

[0080] S3. The vision sensor 14 detects the back-burning position information of the workpiece 2 to be back-burned.

[0081] Specifically, the vision sensor 14 detects the position of the first reinforcing beam 22 located at the end of the workpiece 2 to be back-burned, that is, the back-burning position information is obtained.

[0082] Among them, the dimension information of the workpiece 2 to be back-burned can be input into the controller in advance. The controller can obtain the positions of all the reinforcing beams 22 based on the dimension information of the workpiece 2 to be back-burned and the position of the first reinforcing beam 22.

[0083] S4. The controller controls the back-burning assembly 12 to move according to the back-burning position information, so that the torch 123 corresponds to the position to be back-burned on the workpiece 2 to be back-burned.

[0084] Specifically, after the size of the workpiece 2 to be back-fired is determined in advance, the distance between two adjacent reinforcing beams 22 is also determined. Therefore, the interval between two adjacent torches 123 can be adjusted in advance so that each torch 123 corresponds to a reinforcing beam 22.

[0085] The controller controls the movement of the cross beam 122 of each back-firing assembly 12 according to the back-firing position information of the first reinforcing beam 22 detected by the vision sensor 14, so that the torch 123 at the head end corresponds to the first reinforcing beam 22, thereby enabling each torch 123 to correspond to a reinforcing beam 22.

[0086] It should be noted that the distance between two adjacent back-firing assemblies 12 is determined. Therefore, the controller can control the movement of the cross beam 122 to enable each torch 123 of multiple groups of back-firing assemblies 12 to correspond to a reinforcing beam 22.

[0087] S5. The conveying mechanism 13 moves, causing the workpiece 2 to be back-fired to pass longitudinally through the back-firing assembly 12 to complete the back-firing.

[0088] When the conveying mechanism 13 moves the workpiece 2 to be back-fired, it detects whether the workpiece 2 to be back-fired is approaching or moving away from the torch 123 and controls the opening or closing of the torch 123 according to the detected signal.

[0089] After the ignition sensor of the torch 123 detects the edge of the workpiece 2 to be back-fired, it controls the gun head to start and the back-firing begins.

[0090] After the conveying mechanism 13 moves and the entire workpiece 2 to be back-fired passes through the torch 123, when the ignition sensor detects that the workpiece 2 to be back-fired has left its detection range, the gun head closes. The back-firing process is completed.

[0091] At the start of the back-firing, the distance sensor 127 detects the vertical distance between the gun head and the workpiece 2 to be back-fired. A preset height is set in the controller. The controller controls the lifting drive 126 to start according to the difference between the real-time distance detected by the distance sensor 127 and the preset height, so that the gun head is lifted or lowered to the preset height.

[0092] During the movement of the conveying mechanism 13 with the workpiece 2 to be back-fired and during the back-firing process, the distance sensor 127 also detects the distance in real time. The controller also controls the lifting drive 126 to start according to the difference between the real-time distance detected by the distance sensor 127 and the preset height, so that the gun head is lifted or lowered to the preset height. Therefore, by adjusting the vertical distance, it is ensured that when the back-firing assembly 12 performs back-firing, each part of the workpiece 2 to be back-fired can obtain a consistent back-firing effect, and all are good back-firing effects.

[0093] The controller controls the speed of the conveying mechanism 13 passing through the back-burning assembly 12 according to the thickness dimension of the workpiece 2 to be back-burned. That is, the workpiece 2 to be back-burned with a larger thickness passes through the back-burning assembly 12 at a smaller speed, so as to obtain a longer back-burning time.

[0094] This back-burning method moves the workpiece 2 to be back-burned to the back-burning assembly 12 by the movement of the conveying mechanism 13 along the track 11, collects the back-burning position signal through the vision sensor 14, adjusts the position of the torch 123 relative to the workpiece 2 to be back-burned according to the back-burning position information, and realizes the back-burning of the workpiece 2 to be back-burned through the back-burning assembly 12. This back-burning method has a high degree of automation, improves the back-burning efficiency and the back-burning quality.

[0095] Although the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be broadly construed within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
