Description

Technical Field

[0001] The present application relates to the technical field of shipbuilding, and in particular, to a device and method for spraying and printing the identity and assembly information of ship parts. Background Art

[0002] The hull structure is assembled by many parts of different sizes and styles in sequence. According to the assembly and installation requirements of the hull structure, each part needs to be classified and numbered, that is, a proprietary identity feature is set, so as to facilitate the installation of parts and prevent omissions and misinstallations during the part installation process.

[0003] In the prior art, the identity information of parts is marked during the part blanking process, that is, after the steel plate cutting is completed, workers use a paint pen to manually write the identity information of the parts on the steel plate. In different ship types, the number of hull parts is large, ranging from hundreds of thousands to millions. Therefore, the workload of marking the hull part information is huge. Moreover, when marking the part identity information, repetitive steps such as consulting, writing, and checking the part identity information are also required, resulting in problems such as low work efficiency and heavy labor load, and easily generating hidden dangers such as missing writing, wrong writing, and irregular writing, which affect the integrity assembly of the later hull structure.

[0004] Currently, the assembly line of parts mainly uses zinc powder in the cutting machine to draw lines during the part cutting stage, resulting in problems such as the line width of the lines cannot be guaranteed and the graphics are not clear. Due to the poor scribing accuracy, many scribings need to be re-scribed after secondary positioning, seriously affecting the installation accuracy and efficiency of the later hull structural parts.

[0005] In the prior art, in addition to manual marking or scribing, there is also a spraying and coding tooling device similar to the principle of a single-pen plotter, which can mark or scribe on a flat steel plate. However, when drawing complex graphics, especially when drawing curves or oblique lines, it is easy to produce uneven line thickness and uneven smooth transition of curves, affecting the installation accuracy of later parts. Therefore, the scribing accuracy of existing equipment cannot fully meet the requirements of high-precision ship manufacturing. On the other hand, such equipment has problems such as slow working speed, low efficiency, and high failure rate, so it is difficult to meet the rhythm requirements of shipbuilding.

[0006] During the installation process of ship parts, the identity information and installation position lines of parts are important bases for ensuring the construction accuracy of ships. Therefore, how to provide a device and method for quickly spraying and printing the identity and assembly information of ship parts, improving the accuracy and efficiency of writing and scribing of ship parts, and reducing the shipbuilding cycle has become an urgent problem to be solved in this field.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] In addition, in the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0043] According to the first aspect of the present application, refer to Figures 1 to 8 , first provide an inkjet printing device for the identity and assembly information of ship parts, including:

[0044] A placing table 2, with first guide rails 3 arranged on both sides of the placing table 2, and the placing table 2 is used for placing the steel plate 1 to be inkjet printed.

[0045] The moving trolley 5 is mounted on the first guide rail 3. The moving trolley 5 is electrically connected to the first motor, and the movement of the moving trolley 5 along the first guide rail 3 is controlled by the first motor. A cross beam 8 is arranged on the top surface of the moving trolley 5;

[0046] It should be noted that, as Figures 1 to 4 shown, limit blocks 23 are arranged at both ends of the first guide rail 3, and the limit blocks 23 are used to prevent the moving trolley 5 from sliding out of the first guide rail 3.

[0047] A sliding seat 7 is slidably connected to the upper part of the cross beam 8. An elevating motor and a connecting plate 10 are respectively arranged on the outer side surface of the sliding seat 7, and the output shaft of the elevating motor is threadedly connected to the top surface of the connecting plate 10;

[0048] An inkjet coding mechanism is arranged at the bottom of the connecting plate 10. After the elevating motor rotates, the height of the top of the connecting plate 10 is controlled to be adjusted, so as to adjust the height of the inkjet coding mechanism.

[0049] Specifically, as Figures 1 to 4 shown, the sliding seat 7 is a U-shaped seat covering the top of the cross beam 8. The sliding seat 7 includes a top plate and two side plates. A first elevating motor 9 and a second elevating motor 22 are respectively arranged on one of the side plates. The output shafts of the first elevating motor 9 and the second elevating motor 22 both extend downward, and threaded rods are respectively connected at the output shafts of the first elevating motor 9 and the second elevating motor 22. The bottoms of the threaded rods are both threadedly connected to the connecting plate 10. The first elevating motor 9 and the second elevating motor 22 are arranged along the width direction of the connecting plate 10. By rotating the first elevating motor 9 and the second elevating motor 22, the heights of both sides of the connecting plate 10 are respectively adjusted, so as to adjust the heights of both sides of the inkjet coding mechanism, and the adjustment can be made according to the height of the surface of the curved steel plate to ensure the uniformity and accuracy of the inkjet coding.

[0050] A control mechanism 4 is electrically connected to the first motor, the second motor, the first elevating motor 9, and the second elevating motor 22 respectively, so as to control the movement of the inkjet coding mechanism on the steel plate 1 to be printed, and at the same time adjust the heights of both sides of the inkjet coding mechanism.

[0051] It should be noted that the first guide rail 3 is arranged along the length direction of the steel plate 1 to be printed, and the cross beam 8 is arranged along the width direction of the steel plate 1 to be printed.

[0052] It also should be noted that the connection structure between the moving trolley 5 and the first guide rail 3 includes but is not limited to:

[0053] Roller connection structure, slider-guide rail connection structure, magnetic attraction connection structure, and gear-rack connection structure.

[0054] Specifically, the roller - type connection structure between the mobile trolley 5 and the slide rail includes a roller assembly provided on the mobile trolley 5 and a guide groove on the slide rail. The roller assembly consists of multiple rollers symmetrically distributed. Each roller is installed on the bracket 16 at the bottom of the mobile trolley 5 through an independent bearing. This symmetric distribution design enables the mobile trolley 5 to be evenly stressed when moving on the slide rail, reducing shaking or deviation caused by uneven stress. The guide groove is opened on the two side edges of the slide rail, and its shape is adapted to the outer contour of the roller. The roller rolls within the guide groove.

[0055] The slider - guide - type connection structure between the mobile trolley 5 and the slide rail includes a slider provided at the bottom of the mobile trolley 5 and a guide rail provided on the slide rail to cooperate with it. The slider is made of high - strength alloy material and is internally provided with multiple balls or rollers to form a rolling friction pair. The cross - sectional shape of the guide rail is T - shaped, dovetail - shaped or rectangular, etc., and closely fits the inner contour of the slider. Taking the dovetail - shaped guide rail as an example, the inner groove of the slider is dovetail - shaped, which can constrain the mobile trolley 5 in three dimensions, effectively preventing the mobile trolley 5 from shaking and deviating in the vertical and horizontal directions and ensuring its stable movement on the slide rail. On the contact surface between the slider and the guide rail, a lubrication channel is also provided. By injecting lubricating oil or grease, the friction coefficient is further reduced and wear is decreased. In addition, an elastic pre - tightening device is provided on the slider, which can adjust the contact pressure between the slider and the guide rail according to actual needs to ensure the stability and reliability of the connection.

[0056] The magnetic - adsorption - type connection structure between the mobile trolley 5 and the slide rail includes multiple electromagnets arranged at intervals on the slide rail, and a magnetic adsorption device is correspondingly installed on the mobile trolley 5. The electromagnet is connected to an external power supply through a control circuit, and the on - off state and magnetic force magnitude of the electromagnet can be controlled as needed. The magnetic adsorption device uses high - performance permanent magnetic materials such as neodymium - iron - boron magnets, which have a strong adsorption force. When the mobile trolley 5 needs to move on the slide rail, the electromagnet is energized to generate magnetism and attracts the magnetic adsorption device on the mobile trolley 5, making the mobile trolley 5 tightly connected to the slide rail. By adjusting the magnetic force magnitude of the electromagnet, the connection strength between the mobile trolley 5 and the slide rail can be controlled to adapt to different operating conditions. During the movement, by utilizing the adsorption effect of the magnetic force, the gap between the mobile trolley 5 and the slide rail can be effectively reduced, improving the movement accuracy and stability. At the same time, the magnetic - adsorption - type connection structure also has the characteristics of quick connection and separation, facilitating the installation, disassembly and maintenance of the mobile trolley 5.

[0057] The gear-rack connection structure between the mobile trolley 5 and the slide rail includes a rack provided on one side of the slide rail, and a gear transmission mechanism meshing with the rack is installed on the mobile trolley 5. The gear transmission mechanism includes a motor, a reducer and a gear, and the motor is connected to the gear through the reducer to provide power for the rotation of the gear. When the motor is started, the speed is reduced and the torque is increased by the reducer, and the drive gear rotates on the rack, thereby driving the mobile trolley 5 to move on the slide rail. In order to ensure the correct meshing of the gear and the rack, a guide wheel is also provided on the mobile trolley 5, and the guide wheel contacts the side of the slide rail to guide and constrain the moving direction of the mobile trolley 5. At the same time, the tooth profile of the gear and the rack is optimized and designed, and an involute tooth profile is adopted, which can improve the transmission efficiency and reduce the impact and noise during the transmission process. In addition, the gear-rack connection structure can also realize various motion states of the mobile trolley 5 such as forward, backward, acceleration and deceleration by changing the direction and speed of the motor, and has a strong motion control ability.

The control mechanism 4 adjusts the height of both sides of the connecting plate 10 through the first lifting motor 9 and the second lifting motor 22 according to the distance, so as to adjust the height of both sides of the coding mechanism in real time.

[0062] In an implementable manner, the mounting plate 13 is a trapezoidal plate arranged forward; the width of the bottom edge of the mounting plate 13 is equal to the width of the connecting plate 10, so that when the mounting plate 13 is attached to the connecting plate 10, mounting areas are formed on both sides of the top of the mounting plate 13;

[0063] A first fine-tuning motor 11 and a second fine-tuning motor 20 are respectively arranged on the mounting areas on both sides.

[0064] In an implementable manner, a first height sensor 15 and a second height sensor 18 are respectively arranged at the bottom of the mounting plate 13. During the inkjet printing process, the real-time distances between the bottom surface of the mounting plate 13 and the steel plate 1 to be printed are respectively obtained by the first height sensor 15 and the second height sensor 18 and sent to the control mechanism 4. The control mechanism 4 finely adjusts the first fine-tuning motor 11 and the second fine-tuning motor 20 according to the real-time distances, so that the bottom plane of the inkjet printing mechanism is kept consistent with the steel plate plane, thereby improving the inkjet printing quality.

[0068] In an implementable manner, the bottom of the mounting plate 13 further includes a light curing lamp assembly 25. During the inkjet printing process, the imprint information is dried and cured by the light curing lamp assembly 25.

[0069] In an implementable manner, a laser scanner 21 is provided at the front end of the sliding seat 7. Before inkjet coding, the position information of the steel plate 1 to be printed is obtained by the laser scanner 21 and sent to the control mechanism 4.

[0072] It should be noted that the position information at least includes the height difference of the steel plate edge, the origin coordinates of the steel plate, and the specific position where the steel plate is placed. After the scanning is completed, the laser scanner 21 sends the data to the control mechanism 4 for uploading.
