[0038] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0039] In this embodiment, the X direction (101), the Y direction (102), the Z direction (103) and the A direction (104) are as follows: Figure 1 The direction definitions shown in .

[0040] A specific embodiment of the utility model is as follows Figure 1 As shown, a marine profile coding and marking device is disclosed, including a workbench 1, a swing angle positioning mechanism 2, a clamping positioning mechanism 3, an X-direction column changing mechanism 4, a Y-direction line changing mechanism 5, a coding component 6 and a control system 7.

[0041] It is used to support the profile, the clamping and positioning mechanism 3 and the control system 7 are fixed on the workbench 1, the swing angle positioning mechanism 2 is rotatably connected to the clamping and positioning mechanism 3, the Y-direction line-changing mechanism 5 is movably installed on the swing angle positioning mechanism 2, and the inkjet assembly 6 includes a spray terminal 61, which is fixed on the Y-direction line-changing mechanism 5, and the nozzle of the spray terminal 61 is perpendicular to the X-direction, and the X-direction column-changing mechanism 4 is fixed on the ground or the workbench 1. The swing angle positioning mechanism 2 and the clamping and positioning mechanism 3 can respectively locate the A-direction zero return angle and the Y-direction zero return position of the spray terminal 61 during the inkjet marking process; the X-direction column-changing mechanism 4 and the Y-direction line-changing mechanism 5 are used to complete the column-changing and line-changing process of the device on the profile workpiece; the control system 7 can control the coordinated action of the swing angle positioning mechanism 2, the clamping and positioning mechanism 3, the X-direction column-changing mechanism 4, the Y-direction line-changing mechanism 5 and the inkjet assembly 6 according to the processing file, so as to complete the high-precision and high-quality inkjet and line-marking processing.

[0042] Specifically, a plurality of transmission rollers 11 are fixedly mounted on the upper portion of the workbench 1 . The plurality of transmission rollers 11 are arranged in parallel along the X direction, and can support the bottom of the profile workpiece and can cooperate with the movement of the profile workpiece in the X direction.

[0043] Further, such as Figure 6 As shown, the clamping and positioning mechanism 3 includes a fixing unit 31 and a sliding unit 32 , and the sliding unit 32 can slide toward the fixing unit 31 to clamp two sides of the profile workpiece on the workbench 1 .

[0044] Specifically, the fixed unit 31 includes a Y-direction positioning roller 311, a Y-direction positioning cylinder 312, a slide rail 313 and a slide drag chain 314, and the Y-direction moving unit 32 includes a Y-direction slide 321, a Y-direction clamping roller 322 and a Y-direction clamping roller connecting arm 323. The slide rail 313 is fixed on the workbench 1 and arranged parallel to the transmission roller 11 along the Y direction. The Y-direction positioning cylinder 312 is fixed on the workbench 1 and can drive the Y-direction slide 321 to slide along the slide rail 313 along the Y direction. Two Y-direction positioning rollers 311 are fixed on the workbench 1, located at one end of the slide rail 313, and arranged in parallel along the X direction. The Y-direction clamping roller connecting arm 323 is fixed on the Y-direction slide 321, and two Y-direction clamping rollers 322 are fixed at both ends of the Y-direction clamping roller connecting arm 323. The two Y-direction clamping rollers 322 are arranged in parallel along the X direction and parallel to the two Y-direction positioning rollers 311.

[0045] When performing Y-axis positioning on the profile workpiece, the control system 7 controls the Y-axis positioning cylinder 312 so that the Y-axis positioning cylinder 312 drives the Y-axis slide 321 to slide on the slide guide 313 toward the two Y-axis positioning rollers 311. When the two Y-axis clamping rollers 322 contact one side of the profile workpiece and the two Y-axis positioning rollers 311 contact the other side of the profile workpiece, the Y-axis positioning cylinder 312 enters elastic pressure holding and stops driving, so that the two sides of the profile workpiece are elastically attached to the two Y-axis positioning rollers 311 and the two Y-axis clamping rollers 322 respectively, thereby completing the Y-axis return to zero positioning of the inkjet terminal 61 during the coding and marking process.

[0046] It should be noted that the stroke design of the Y-axis slide 321 determines the specifications of the profile workpiece. For example, the web size of the bulb flat steel profile workpiece with the largest usage in the shipyard can be easily expanded to 430 mm or even larger.

[0047] Further, such as Figure 4 The swing angle positioning mechanism 2 shown includes a printer frame 21, a swing angle mechanism 22, a swing angle return zero pressure roller 23 and a lower limit positioning roller 24. The printer frame 21 is located on one side of the swing angle mechanism 22, and includes a frame control end 211 and a frame free end 212, and the frame control end 211 is connected to the swing angle mechanism 22. The swing angle mechanism 22 is installed on the workbench 1, and the swing angle mechanism 22 can drive the frame control end 211 to rotate the printer frame 21 around the frame control end 211, so that the frame control end 211 is lifted upward and stays in a tilted state, so that the profile workpiece is conveyed to the printer frame 21 The inkjet area 83 in the lower direction of the inkjet frame 21. The swing angle return-to-zero pressure roller 23 is fixed under the inkjet printer frame 21, and is used to fit the inkjet printing surface of the profile workpiece, so that the inclination angle of the inkjet terminal 61 is returned to zero position; the lower limit positioning roller 24 is fixed on the Y-axis slide 321, and is used to support the lower part of the edge line of the profile workpiece, and plays an auxiliary role in the lower limit positioning of the profile workpiece.

[0048] This embodiment adopts a cross-connection structure in which one end of the inkjet printer frame 21 is connected to the side of the swing angle mechanism 2, so that a driving force can be applied to the inkjet printer frame 21 from the side, avoiding the restriction of the swing angle mechanism 2 on the operating angle of the inkjet printer frame 21, so that the inkjet printer frame 21 can achieve a 0-90° rotation around the frame control end 211, so that profile workpieces of more specifications can enter the inkjet printing area, greatly improving the processing capacity and range of the profile inkjet printing and marking device.

[0049] Furthermore, in order to achieve precise zero positioning of the angle of the web of the profile workpiece, the swing angle mechanism 22 of this embodiment is an elastic adaptive structure, which can enable the bottom of the swing angle zero pressure roller 23 to elastically fit the surface of the web of the profile workpiece of different specifications.

[0050] Specifically, Figure 5 As shown, the swing angle mechanism 22 includes a swing angle bracket 221, a swing angle assembly 222, a first tension spring 223, a second tension spring 224, a swing angle cylinder 225 and a limit stopper 226. The swing angle bracket 221 is vertically fixed on the Y-axis slide 321, the top of the swing angle cylinder 225 is hinged to the top of the swing angle bracket 221, and the lower end of the swing angle cylinder 225 is hinged to the swing angle assembly 222; the two ends of the first tension spring 223 are fixedly connected to the swing angle bracket 221 and the free end 212 of the frame, and the two ends of the second tension spring 224 are fixedly connected to the swing angle bracket 221 and the swing angle assembly 222; the frame control end 211 is fixed to the swing angle assembly 222.

[0051] Preferably, the swing angle assembly 222 includes a swing angle shaft 2221, a swing angle shaft slide plate 2222 and a swing angle bearing 2223. A vertical slideway is arranged on the swing angle bracket 221, and the swing angle shaft slide plate 2222 can slide vertically on the swing angle bracket 221 along the slideway. A limit stopper 226 is fixed on the swing angle bracket 221, and the limit stopper 226 can limit the upper limit position of the sliding of the swing angle bracket 221. The swing angle shaft slide plate 2222 is fixedly connected to one end of the second tension spring 224. The swing angle shaft 2221 is a crank-type transfer shaft, and preferably, the crank connecting rod of the swing angle shaft 2221 is located in the middle section of the rotating shaft. The rotating shaft of the swing angle shaft 2221 is rotatably connected to the swing angle shaft slide plate 2222 via the swing angle bearing 2223 , and one end of the rotating shaft of the swing angle shaft 2221 is fixedly connected to the frame control end 211 , and the crank connecting rod of the swing angle shaft 2221 is hinged to the driving end of the swing angle cylinder 225 .

[0052] When the profile workpiece is conveyed to the coding area of ​​the device, the angular swing mechanism 22 follows the Y-axis slide 321 to move toward the profile workpiece until the two Y-axis clamping rollers 322 elastically fit the edge of the profile workpiece, and the clamping positioning mechanism 3 completes the Y-axis return to zero positioning. At the same time, the control system 7 controls the swing angle cylinder 225 to stretch, so that the inkjet bracket 21 descends. At this time, the swing angle axis slide plate 2222 does not move due to the spring tension of the second tension spring 224. Therefore, the frame control end 211 does not descend, and the frame free end 212 falls due to the gravity of the inkjet bracket 21 itself. When the swing angle return to zero pressure roller 23 below the frame free end 212 presses the profile workpiece, the swing angle cylinder 225 overcomes the tension of the second tension spring 224, so that the swing angle axis slide plate 2222 slides downward, thereby causing the frame control end 211 to descend until the swing angle return to zero pressure roller 23 below the frame control end 211 also contacts the profile workpiece, and flexibly fits with the processing surface of the profile workpiece, so that the inkjet terminal 61 can be perpendicular to the processing surface of the profile workpiece, and accurately realizes the A-axis angle return to zero.

[0053] When the control system 7 controls the swing angle cylinder 225 to contract, the frame control end 211 is first pulled up until the swing angle axis slide plate 2222 hits the limit stop block 226, and then the frame free end 212 is pulled up and rotates in direction A around the frame control end 211, so that the inkjet printer bracket 21 returns to the preset position.

[0054] The swing angle mechanism 22 of this embodiment can better adapt to the various types of marine profile workpieces, the large angle changes of the web or wing plate, and the presence of bending and deformation by setting an adaptive profiling structure, so that the nozzle always remains perpendicular to the web or wing plate of the profile workpiece when spraying and marking, greatly improving the marking accuracy, spraying quality and aesthetics. Figure 2 and Figure 3 As shown, since there are many specifications of marine profile workpieces, including bulb flat steel, equilateral angle steel, unequal angle steel, flat steel, H-shaped steel, I-shaped steel, channel steel, square tube, rectangular tube and many other specifications. When it is necessary to perform coding and marking on the web or wing plate, the inclination angle between the spray terminal 61 and the workbench 1 must meet the working range of 0-90°. This embodiment adopts a cross-connection structure in which the control end 211 of the coding machine frame is connected to the side of the swing angle mechanism 2, which can avoid the restriction of the swing angle mechanism 2 on the operating angle of the coding machine frame 21, so that the coding machine frame 21 can achieve 0-90° rotation around the frame control end 211, thereby meeting the requirements for coding and marking the wing plates of profile workpieces such as H-shaped steel, I-shaped steel, channel steel, square tube, rectangular tube, etc.

[0055] Further, if Figure 7As shown, the X-direction column-changing mechanism 4 includes a clamping arm assembly 41, an X-direction slide 42, an X-direction guide rail assembly 43 and an X-direction motor assembly 44. The X-direction guide rail assembly 43 is located above the workbench 1, and is fixed to the ground below by a plurality of pillars, and can also be fixedly connected to the workbench 1. The X-direction guide rail assembly 43 includes a guide rail and a rack arranged in the X direction; the X-direction slide 42 is provided with a slider matched with the guide rail; the X-direction motor assembly 44 is fixed on the X-direction slide 42, and includes an X-direction servo motor, a motor reducer and a transmission gear, and the transmission gear is meshed with the rack of the X-direction guide rail assembly 43. When the control system 7 controls the X-direction servo motor to work, the X-direction slide 42 can slide along the X-direction straight line on the guide rail through the cooperation of the transmission gear and the rack of the X-direction guide rail assembly 43. The clamp arm assembly 41 includes a clamp arm 411 , a clamp 412 and a hydraulic cylinder 413 . The hydraulic cylinder 413 is fixed on the X-axis slide 42 . One end of the clamp arm 411 is connected to the output end of the hydraulic cylinder 413 , and the other end is provided with the clamp 412 .

[0056] Before starting the coding and marking process, the profile workpiece is first placed on the workbench 1, and the control system 7 controls the X-axis motor to move the X-axis slide 42 toward the profile workpiece. When the clamp 413 is located at one end of the profile workpiece, the control system 7 controls the hydraulic cylinder 412 to make the clamp arm 411 drive the front clamp 413 to clamp one end of the profile workpiece; at the same time, the control system 7 controls the X-axis servo motor to move the X-axis slide 42 continuously until the coding area of ​​the profile workpiece is sent into the coding and marking working area of ​​the coding and marking device.

[0057] When the coding and marking process is being performed, the control system 7 controls the motor of the X-direction motor assembly 44 to make the X-direction slide 42 slide back and forth on the guide rail, so that the clamp arm 411 and the clamp 413 apply a thrust or a pull force to the profile workpiece in the X direction, and cooperate with the coding assembly 6 to complete the X-direction column switching action of the coding and marking process. The X-direction column switching mechanism 4 controls the sliding of the X-direction slide 42 on the X-direction guide rail assembly 43, pulling the profile workpiece to move back and forth smoothly on the transmission roller, making the X-direction column switching operation of the coding and marking process faster, more flexible, more accurate and controllable.

[0058] Further, such as Figure 8 As shown, the Y-direction line-changing mechanism 5 includes a Y-direction line-changing slider 51, a Y-direction linear guide 52, a Y-direction motor assembly 53, a synchronous belt assembly 54 and a frame drag chain 55. The Y-direction linear guide 52 is arranged on one side of the inkjet printer frame 21, the Y-direction motor assembly 53 is fixed to one end of the inkjet printer frame 21 connected to the swing angle mechanism 22, the synchronous belt assembly 54 is fixed to the inkjet printer frame 21, and the synchronous belt assembly 54 and the Y-direction linear guide 52 are parallel to each other and are located on the same side of the inkjet printer frame 21. The Y-direction line-changing slider 51 is fixed on the synchronous belt of the synchronous belt assembly 54, and a nozzle base is fixed on the Y-direction line-changing slider 51 for fixing the inkjet printer terminal 61.

[0059] When performing inkjet marking, the control system 7 controls the motor of the Y-direction motor assembly 53 to make the synchronous belt assembly 54 drive the Y-direction line-changing slider 51 to slide back and forth on the Y-direction linear guide 52, thereby driving the inkjet terminal 61 to complete the Y-direction line-changing action of the inkjet marking process. The Y-direction line-changing mechanism 5 adopts the synchronous belt assembly 54, which can make the Y-direction line-changing action precise, controllable, fast and smooth; in addition, by fixing the Y-direction line-changing mechanism 5 on the inkjet printer frame 21, the inkjet terminal 61 fixed on the Y-direction line-changing mechanism 5 can synchronously complete the Y-direction zero positioning and angle zeroing with the inkjet printer frame 21 while performing the Y-direction line-changing, making the multi-dimensional and multi-parameter inkjet marking process simpler and faster, and reducing the errors of multiple degrees of freedom.

[0060] Furthermore, the nozzle direction of the spray terminal 61 is perpendicular to the swing angle return to zero pressure roller 23, thereby ensuring that when the swing angle positioning mechanism 2 is in the angle return to zero state, the spray direction of the spray terminal 61 remains perpendicular to the profile web surface, so as to achieve high-quality, high-precision and beautiful coding and marking effects.

[0061] Furthermore, the control system 7 is fixed on the workbench 1, and can perform system integration and coordinated control of the swing angle positioning mechanism 2, the clamping positioning mechanism 3, the X-axis column changing mechanism 4, the Y-axis line changing mechanism 5 and the coding component 6, so as to complete the coding and marking operations of various specifications of marine profiles with high quality and high precision, and further can realize integrated linkage with other existing CNC and robot profile cutting production lines.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
