Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, specifically to a method and system for marking and coding profiles. Background Technology

[0002] The shipbuilding industry requires the extensive use of various types of profiles. In the current shipbuilding process, most shipbuilding companies place the profile cutting unit and the marking and scribing unit at the same workstation. As a result, the mismatch between the marking and scribing operation cycle and the cutting operation cycle makes the efficiency of profile marking and scribing extremely low. In addition, each process based on marking and scribing is relatively cumbersome, complex and independent. The existing technology for marking and scribing profiles often requires manual product turnover between each process. This not only requires high labor costs, but also cannot guarantee the accuracy of profile marking and scribing. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention discloses a method and system for inkjet marking and scribing on profiles, which improves the efficiency and accuracy of inkjet marking and scribing on profiles.

[0004] To achieve the above objectives, this invention discloses a method for inkjet marking and scribing on profiles, comprising:

[0005] Obtain the positioning information when the profile is fixed in place, and determine the inkjet marking position of the inkjet marking machine relative to the profile based on the positioning information;

[0006] Receive the inkjet marking information and size information corresponding to the profile, and calculate the inkjet marking trajectory of the inkjet marking machine;

[0007] Based on the inkjet marking trajectory and the inkjet marking position, the inkjet marking machine is controlled to perform inkjet marking on the profile.

[0008] This invention discloses a method for inkjet marking on profiles. First, positioning information of the profile when it is fixed is obtained. This information is used to adjust the inkjet marking machine's position relative to the profile, ensuring that the inkjet marking machine performs the marking operation in accordance with the actual condition of the profile, thus improving the accuracy of the marking. Further, the inkjet marking trajectory of the machine is calculated based on the received inkjet marking and dimensional information corresponding to the profile, reducing the impact of profile deformation on the marking and improving accuracy. Finally, the obtained marking position and trajectory are used to control the machine to perform the marking task.

[0009] As a preferred example, obtaining the positioning information when the profile is fixedly placed includes:

[0010] The laser detection device preset on the inkjet marking machine is used for real-time detection. When the profile is detected, the intersection angle generated when the laser currently sent by the laser detection device intersects with the profile is obtained.

[0011] The laser detection device is used to obtain the edge line of the ball head side of the profile; wherein, the positioning information includes the intersection angle and the edge line.

[0012] This invention utilizes the laser detection device to position profiles, solving the technical problem of low accuracy caused by relying on manual experience for profile positioning, and improving the accuracy of profile marking and scribing.

[0013] As a preferred example, determining the inkjet marking position of the inkjet marking machine relative to the profile includes:

[0014] By comparing the intersection angle with the preset angle range within the inkjet marking machine, it is determined whether to adjust the angle of the inkjet marking machine.

[0015] When the intersection angle is outside the angle range, adjust the angle of the inkjet marking machine until the intersection angle is within the angle range, and obtain the current angle of the inkjet marking machine as the inkjet marking angle;

[0016] The inkjet marking machine is controlled to move away from the edge line until the distance between the inkjet marking machine and the edge line reaches a preset distance threshold; wherein, the inkjet marking position includes the inkjet marking angle and the distance.

[0017] This invention enables automatic adjustment of the inkjet marking machine by presetting angle ranges and distance thresholds within the machine, eliminating the need for manual adjustment, thus improving adjustment efficiency and consequently increasing the efficiency of inkjet marking.

[0018] As a preferred example, receiving the inkjet marking information and dimension information corresponding to the profile includes:

[0019] The laser detection device scans the profile to obtain its dimensional information, which includes length, width, and height.

[0020] The processing task sheet corresponding to the profile is parsed to obtain the inkjet marking information of the profile.

[0021] This invention calibrates the trajectory of the inkjet printing line based on the dimensional information of the profile, so as to reduce the impact of profile deformation on the inkjet printing line and improve the accuracy of the inkjet printing line.

[0022] On the other hand, the present invention discloses a profile inkjet marking system, including a profile buffer rack, a material conveying device, an inkjet marking rack, an inkjet marking machine, and a main control unit; the main control unit is electrically connected to the material conveying device and the inkjet marking machine respectively;

This main control unit controls the material conveying device to achieve profile turnover and controls the marking and scribing machine to achieve automatic marking and scribing on the profiles. Furthermore, the main control unit performs marking and scribing based on the positioning and dimensional information of the profiles during the marking and scribing process, improving the accuracy of the marking and scribing.

[0032] The present invention provides a support frame for transporting profiles and a clamping mechanism for fixing the profiles in the working area, which facilitates the inkjet marking machine for inkjet marking.

[0033] As a preferred example, the material conveying device includes a transverse conveyor chain, which is located on one side of the support frame and spans the inkjet marking frame and the profile buffer frame. The conveyor chain is fixedly connected to a chain drive mechanism. A receiving head is provided on the conveyor chain. After the receiving head rises to receive the profile, it is transported.

[0038] The present invention provides a laser detection device on the inkjet marking machine to obtain the positioning and dimensional information of the profile, which facilitates subsequent inkjet marking of the profile based on the information of the profile, thereby improving the accuracy of inkjet marking.

[0039] As a preferred example, the main control unit determines whether to adjust the angle of the inkjet marking machine by comparing the cross angle with an angle range preset within the inkjet marking machine; when the cross angle is outside the angle range, the angle of the inkjet marking machine is adjusted until the cross angle is within the angle range, and the current angle of the inkjet marking machine is obtained as the inkjet marking angle;

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0051] Example

[0052] This embodiment discloses a method for inkjet marking and scribing on profiles. For the specific implementation process of the inkjet marking and scribing method, please refer to... Figure 1 It mainly includes steps 101 to 103, and the steps are mainly as follows:

[0053] Step 101: Obtain the positioning information when the profile is fixed in place, and determine the inkjet marking position of the inkjet marking machine relative to the profile based on the positioning information.

[0054] In this embodiment, the step mainly includes: real-time detection using a laser detection device preset on the inkjet marking machine; when the profile is detected, obtaining the intersection angle generated when the laser currently sent by the laser detection device intersects with the profile; obtaining the edge line where the ball head side of the profile is located using the laser detection device; wherein, the positioning information includes the intersection angle and the edge line.

[0055] Next, by comparing the intersection angle with a preset angle range within the inkjet marking machine, it is determined whether to adjust the angle of the inkjet marking machine; when the intersection angle is outside the angle range, the angle of the inkjet marking machine is adjusted until the intersection angle is within the angle range, and the current angle of the inkjet marking machine is obtained as the inkjet marking angle; the inkjet marking machine is controlled to move away from the edge line until the distance between the inkjet marking machine and the edge line reaches a preset distance threshold; wherein, the inkjet marking position includes the inkjet marking angle and the distance.

[0056] In this embodiment, this step achieves automatic adjustment of the inkjet marking machine by preset angle range and distance threshold within the inkjet marking machine, eliminating the need for manual adjustment, thus improving adjustment efficiency and consequently increasing the efficiency of inkjet marking.

[0057] Step 102: Receive the inkjet marking information and size information corresponding to the profile, and calculate the inkjet marking trajectory of the inkjet marking machine.

[0058] In this embodiment, the main steps are: scanning the profile using the laser detection device to obtain the profile's dimensional information, wherein the dimensional information includes length, width, and height; and parsing the processing task sheet corresponding to the profile to obtain the inkjet marking information of the profile.

[0059] In this embodiment, this step calibrates the trajectory of the inkjet printing line based on the size information of the profile, so as to reduce the impact of profile deformation on the inkjet printing line and improve the accuracy of the inkjet printing line.

[0060] Step 103: Based on the inkjet marking trajectory and the inkjet marking position, control the inkjet marking machine to perform inkjet marking on the profile.

[0061] On the other hand, this embodiment also provides a profile inkjet marking system, which includes a profile buffer rack, a material conveying device, an inkjet marking rack, an inkjet marking machine, and a main control unit; the main control unit is electrically connected to the material conveying device and the inkjet marking machine respectively.

[0062] The profile buffer rack is used to receive profiles transported from the previous workstation.

[0063] A material conveying device is provided between the inkjet marking frame and the profile buffer frame to transport the profile from the profile buffer frame to the inkjet marking frame.

[0064] The inkjet marking machine is located above the inkjet marking frame and is used to acquire the positioning and dimension information of the profile fixed on the inkjet marking frame, and send the positioning and dimension information to the main control computer.

[0065] The main control unit controls the material conveying device to transport the profile to the inkjet marking frame based on the real-time processing dynamics of the inkjet marking machine, and receives the positioning and dimension information sent by the inkjet marking machine to perform the following operations:

[0066] The inkjet marking position of the inkjet marking machine relative to the profile is determined based on the positioning information;

[0067] Receive the inkjet marking information and size information corresponding to the profile, and calculate the inkjet marking trajectory of the inkjet marking machine;

[0068] The main control unit controls the inkjet marking machine according to the inkjet marking trajectory and the inkjet marking position, so that the inkjet marking machine can perform inkjet marking on the profile.

[0069] In this embodiment, the above-mentioned inkjet marking system ensures uninterrupted profile marking process through the profile buffer rack, improving process redundancy. Then, an inkjet marking rack is set up to fix the profile so that the inkjet marking machine located above the rack can perform inkjet marking and obtain the profile's positioning and dimensional information. Furthermore, a material conveying device is provided between the inkjet marking rack and the profile buffer rack to achieve automatic profile transport, avoiding manual handling and improving efficiency. A main control unit is provided in the inkjet marking system, electrically connected to both the inkjet marking machine and the material conveying device. This unit controls the material conveying device to achieve profile turnover and controls the inkjet marking machine to achieve automatic inkjet marking. Furthermore, the main control unit performs inkjet marking based on the profile's positioning and dimensional information during the marking process, improving the accuracy of the marking.

[0070] Specifically, such as Figures 2 to 6 As shown, refer to Figure 2 The inkjet marking system includes a profile buffer rack 1 for receiving profiles conveyed from the previous station and buffering the profiles, and a material conveying device 2 connected to the profile buffer rack. The material conveying device 2 is used to transport the profiles located on the profile buffer rack 1. (Referring to...) Figure 2 A crane or similar device can be used to place the profiles transported from the previous workstation onto the profile buffer rack 1. The profile buffer rack 1 can buffer multiple profiles. Preferably, refer to Figure 2 The provided profile buffer rack 1 can buffer 5 typical profiles, wherein the typical profiles are 220mm wide, 10mm thick, and 13m long, and the ball head side of the profiles should face the crane side.

[0071] Furthermore, refer to Figure 2 According to the production cycle or the real-time processing dynamics of the inkjet marking machine, the material conveying device 2 connected to the profile buffer rack 1 automatically conveys the profile to the inkjet marking rack. The material conveying device includes a transverse conveying chain, which is located on one side of the support frame and spans the inkjet marking rack and the profile buffer rack. The conveying chain is fixedly connected to a chain drive mechanism. The conveying chain is equipped with a receiving head. After the receiving head rises to receive the profile, it is transported. The chain drive mechanism drives the conveying chain to move, thereby conveying the receiving head to a designated position. Then, the receiving head descends to release the profile onto the material conveying work rack.

[0072] In this embodiment, the material conveying device 2 realizes the automatic turnover of profiles, avoids manual movement of profiles, and improves the efficiency of profile marking and marking.

[0073] Furthermore, refer to Figure 3 and Figure 4, is the inkjet marking frame 3 in the profile inkjet marking system, wherein, referring to Figure 3 and Figure 4 It is known that the inkjet marking frame 3 includes a support frame 31 arranged in the longitudinal direction. The side of the support frame 31 closest to the inkjet marking machine is set as the working area, and the side of the support frame 31 away from the inkjet marking machine is set as the discharge area. A clamping mechanism 32 is provided on the working area. The material conveying device 2 transports the profile to the working area so that the clamping mechanism 32 fixes the profile, and the inkjet marking machine performs inkjet marking.

[0074] In this embodiment, the support frame 31 is provided to transport the profile, and the clamping mechanism is provided in the working area to fix the profile, so as to facilitate the inkjet marking machine to perform inkjet marking.

[0075] Specifically, refer to Figure 3 and Figure 4 It can be seen that the clamping mechanism 32 includes a reference edge 321, a pushing mechanism 322, and a guide roller 323. The guide roller 323 in the inkjet marking frame 3 pushes the profile to the reference edge 321 for fixing, thereby pressing the profile against the reference edge 321. Specifically, the straightness of the reference edge 321 is ensured by machining and subsequent fine adjustment. Specifically, the positioning state of the profile on the clamping mechanism 32 can be referred to Figure 5 Preferably, the pushing mechanism 322 is driven by a cylinder.

[0076] Furthermore, refer to Figure 4 It is understood that a transverse mechanism 33 can also be set on the inkjet marking frame 3. The transverse mechanism 33 is driven by a servo motor and is used to transport the profile with completed inkjet marking to the feeding unit.

[0077] Specifically, after the profile is fixed by the clamping mechanism 32, the inkjet marking machine performs inkjet marking on the profile. The inkjet marking machine is equipped with a laser detection device. The laser detection device is used to obtain the intersection angle generated when the emitted laser intersects with the profile and the edge line where the ball head side of the profile is located. The laser detection device scans the profile to obtain the size information of the profile. The size information includes length, width and height.

[0078] The main control unit determines whether to adjust the angle of the inkjet marking machine by comparing the intersection angle with a preset angle range within the inkjet marking machine. When the intersection angle is outside the angle range, the main control unit adjusts the angle of the inkjet marking machine until the intersection angle is within the angle range, and obtains the current angle of the inkjet marking machine as the inkjet marking angle. The main control unit controls the inkjet marking machine to move away from the edge line until the distance between the inkjet marking machine and the edge line reaches a preset distance threshold. The inkjet marking position includes the inkjet marking angle and the distance. The main control unit parses the processing task sheet corresponding to the profile to obtain the inkjet marking information of the profile.

[0079] Preferably, in this embodiment, a coding and marking robot is used to perform coding and marking on the profile. The coding and marking robot adjusts its angle and distance according to a pre-set main control module within the robot, and then performs coding and marking on the profile. Figure 5 After the rollers 323 in the inkjet marking frame 3 push the profile to the reference edge 321 and fix it, the laser detection device 4 on the inkjet marking robot slowly approaches the end of the profile. After detecting the profile, the robot automatically adjusts the inkjet angle and its distance from the profile. When the laser beam is at a 30° angle to the profile at a distance of 50mm from the ball head, the robot sets the inkjet angle and position. At this time, the detection and positioning on the inkjet marking frame is completed, and the inkjet marking robot performs inkjet marking operation. Furthermore, a laser detection device 4 can also be set at the end of the transverse mechanism 33. The laser detection device 4 also sets the laser beam at a 30° angle to the profile at a distance of 50mm from the ball head.

[0080] Furthermore, a platform can be provided above the inkjet marking frame 3 along the longitudinal direction, and a sliding track is provided on the platform, so that the inkjet marking machine can slide along the length of the profile on the sliding track.

[0081] Specifically, a gantry mechanism is set on the inkjet marking frame 3. The gantry mechanism is a fixed gantry type and includes a crossbeam, column, robot trolley assembly, power supply system, etc. All equipment and accessories in the marking system, such as profile buffer rack 1, material conveying device 2, inkjet marking frame 3, inkjet marking robot, etc., can be installed on the gantry mechanism to enable overall hoisting and relocation without disassembling individual devices, thereby improving the versatility of the system's application scenarios.

[0082] The robot car assembly is driven by the robot's external shaft and uses a rack and pinion transmission, enabling it to achieve high operating speed and positioning accuracy. The marking and marking robot is driven by the robot car assembly and then slides on the gantry mechanism.

[0083] Optional, refer to Figure 6 Furthermore, an automatic inkjet head cleaning device 5 can be installed on the gantry mechanism. Since the inkjet printer uses an integrated ink cartridge with no external piping, the printhead is less prone to clogging. However, after marking, a small amount of ink droplets remain on the printhead, requiring timely wiping to prevent condensation. Therefore, a separate printhead cleaning device 5 is configured and installed on the column of the gantry mechanism 5. Each time marking is completed on a profile, the robot is moved to the printhead cleaning device 6 for printhead cleaning, referring to... Figure 6 The nozzle cleaning device 5 is driven by a pneumatic motor 51. A cleaning head 52 is mounted on its top and equipped with a solvent dispensing device, which can dispense solvent onto the cleaning head 52. When the nozzle needs cleaning, the solvent dispensing device dispenses solvent onto the cleaning head 52, and the pneumatic motor 51 drives the cleaning head 52 to rotate. At this time, the robot moves the nozzle onto the cleaning device, thus completing the nozzle cleaning.

[0084] This embodiment discloses a profile marking and scribing system that optimizes the production cycle of profile cutting and significantly increases the capacity of automated profile cutting production lines. It adopts more advanced and scientific detection methods in the marking device, which improves the accuracy of marking and scribing and profile cutting, and reduces the scrap rate of automated profile cutting production lines. At the same time, it designs more scientific and reasonable repeatable positioning benchmarks and methods in both marking and cutting operations, which improves the accuracy of cutting operations.

[0085] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. In particular, it should be noted that any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention for those skilled in the art.
