Description

Technical Field

[0001] This utility model relates to the field of crane inkjet printing technology, and more specifically, to an inkjet printing auxiliary device for cranes. Background Technology

[0002] In the production and manufacturing process of crane equipment, product model marking (consisting of a combination of fixed code and serial code) is a key link to achieve product traceability, quality control and market differentiation. Manufacturers need to complete the marking before the equipment leaves the factory, and usually use external spray painting process to ensure the wear resistance and visual recognition of the marking.

[0003] Existing external spray painting marking methods mainly fall into two categories: First, a preset model code is first printed on the surface of a special film, then the film is precisely applied to the area to be marked on the equipment, followed by overall spray painting. After the paint film cures, the film is removed to form a clear mark. However, this method has significant drawbacks. Oil stains and metal debris are easily left on the equipment surface during manufacturing, or slight curvature changes on the equipment surface may result in insufficient sealing between the film and the equipment surface, causing paint to easily seep in from the edges of the film during spraying, resulting in blurred marks. At the same time, the solvents used for spray painting can easily corrode the film substrate, causing the film to peel or fall off before the paint film cures. This not only requires rework but may also contaminate the equipment surface, increasing production losses.

[0004] Secondly, the corresponding model number grooves are machined into the inkjet printing panel using an engraving process. After the inkjet printing panel is fixed to the surface of the equipment, it is painted, and then the inkjet printing panel is removed to complete the marking. However, this method has significant limitations in mass production scenarios. A single inkjet printing panel can only match one model number. If the manufacturer produces multiple models of equipment at the same time or needs to frequently switch models, a large number of inkjet printing panels of different specifications need to be engraved in advance, which is both time-consuming and occupies a lot of storage space. Each model change also requires stopping the machine to replace the inkjet printing panel, which seriously affects production efficiency. The production and disposal of a large number of inkjet printing panels also further increases material costs. Utility Model Content

[0005] This application mainly addresses the problems of poor versatility, inconvenient replacement, and easy blurring of markings during painting of existing inkjet printing panels. To overcome the above-mentioned defects of the prior art, this application provides an inkjet printing auxiliary device for cranes.

[0006] This application provides a coding auxiliary device for a crane, including a coding panel, wherein the coding panel is provided with a fixed coding forming part and a sequential coding forming part; The fixed coding forming part includes multiple fixed coding font slots with a hollow structure, and the multiple fixed coding font slots are integrally formed on the inkjet panel; The sequence coding forming part includes multiple sequence coding windows with a hollow structure. The multiple sequence coding windows are arranged at intervals along the length direction of the inkjet panel. Each sequence coding window is equipped with a coding plate. The area of ​​the coding plate is larger than the area of ​​the sequence coding window. Each coding plate has a corresponding sequence coding font slot hollowed out. The inkjet panel and the encoder plate are provided with a connecting part for detachably connecting the encoder plate to the inkjet panel.

[0007] Compared with existing technologies, the coding auxiliary device for cranes disclosed in this application has the following advantages: Through the combined structure of an integrated fixed coding section and a detachable coding plate for the sequence coding section, it eliminates the need to manufacture a large number of complete coding panels for different equipment models. Only the coding plate corresponding to the sequence code needs to be replaced, significantly reducing the number of panels required, saving storage space and material costs, and avoiding frequent downtime for replacing entire panels, thus improving coding efficiency. The sequence coding plate has a larger area than the sequence coding window, completely covering the window edge. Combined with the detachable connection, it effectively prevents paint from seeping into gaps during spraying, solving the problem of blurred markings caused by poor adhesion and solvent erosion in traditional film application, ensuring clear printing of both fixed and sequence codes. The detachable connection supports quick replacement of the coding plate, flexibly responding to frequent changes in equipment models, meeting the needs of high-volume, multi-specification production scenarios, and reducing production losses.

[0008] In one possible implementation, the connecting portion includes a first slot located at the top of the coding panel and a second slot located at the bottom of the coding panel. The first and second slots are parallel to each other and both extend along the length of the coding panel. Each coding board is engaged between the first and second slots and slides along the length of the coding panel. Compared with the prior art, the slot-type connection eliminates the need for complex components. The coding board can be directly engaged into the first and second slots and slide along the length of the coding panel, enabling quick installation and easy adjustment of the coding board position, reducing maintenance costs. Furthermore, the sliding design reduces the difficulty of aligning the coding board. The parallel slots extending along the panel's length provide bidirectional vertical restraint for the coding board, ensuring continuous alignment between the coding board and the sequence coding window, thus improving printing accuracy.

[0009] In one possible implementation, the coding panel is a thin stainless steel plate, with its upper edge folded downwards to form the first slot and its lower edge folded upwards to form the second slot. Compared to existing technologies, the thin stainless steel plate possesses excellent wear resistance and resistance to paint solvent corrosion, resisting the erosion of the panel by solvents during the painting process, while preventing panel deformation due to wear and extending the overall device's service life. By forming the slot through the folding of the panel's own edge, there is no need for additional welding or installation of independent slot components, reducing processing steps and the number of parts, thus lowering manufacturing costs. Furthermore, the folding structure integrates the slot with the panel, improving the slot connection strength, preventing the risk of slot detachment, and enhancing structural stability.

[0010] In one possible implementation, the gap of the first slot is smaller than the thickness of the encoding plate; the gap of the second slot is also smaller than the thickness of the encoding plate. Compared with the prior art, the interference fit design of "slot gap smaller than encoding plate thickness" can tightly lock the encoding plate in the slot, eliminating the gap between the encoding plate and the slot. This effectively prevents the encoding plate from loosening or shifting due to vibration or operation during the painting process, ensuring that the encoding plate is always precisely aligned with the sequence encoding window. This fundamentally avoids the problems of sequence encoding blurring and positional offset caused by encoding plate displacement, reduces rework rate, and improves painting yield.

[0011] In one possible implementation, the connecting part is a magnetic structure, comprising a first magnetic component fixed to the inkjet panel and a second magnetic component fixed to the coding plate, wherein the first and second magnetic components are magnetically matched and attracted to each other. Compared with the prior art, the magnetic connection method eliminates the need for complex actions such as plugging and unplugging or snapping. Replacing the coding plate only requires magnetic attraction and separation, significantly shortening model changeover time. This is particularly suitable for multi-batch, fast-paced production scenarios, improving operational efficiency. The precise matching of the first and second magnetic components ensures a tight fit between the coding plate and the inkjet panel, reducing gaps and preventing paint from seeping into the gaps and blurring the marking edges. Furthermore, the magnetic structure has no mechanical wear, resulting in low maintenance costs and a long service life.

[0012] In one possible implementation, an annular positioning groove is provided on the periphery of the sequence encoding window, and the encoding plate is inserted into the annular positioning groove. Compared with the prior art, the annular positioning groove can form a circumferential limit on the encoding plate, guide the encoding plate to accurately insert into the corresponding sequence encoding window position, avoid the encoding plate offset caused by visual errors during manual installation, ensure the alignment accuracy between the encoding plate and the window after each installation, and ensure consistent sequence encoding printing position.

[0013] In one possible implementation, the back of the coding panel is provided with a magnetic adsorption layer for magnetically attaching the coding panel to the surface of the metal device to be coded. Compared with the prior art, the magnetic adsorption layer can directly and tightly adsorb the coding panel onto the surface of the metal device without the need for clamps, glue, or tape, avoiding the problems of damage to the device surface and difficult-to-clean glue residue caused by traditional clamps. Moreover, installation and removal can be completed in just a few seconds, greatly improving the fixing efficiency.

[0014] In one possible implementation, the front of the inkjet panel has a mother mark corresponding to a sequence coding window, and the coding plate has a child mark matching the mother mark. Compared with the prior art, by visually matching the mother mark and the child mark, the operator does not need to use additional measuring tools such as rulers and calipers. They only need to observe whether the two are aligned to determine the installation accuracy of the coding plate, simplifying the alignment operation process, lowering the operation threshold, and making it especially suitable for fast operation scenarios.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Example 1 See Figures 1 to 6 This application discloses a coding auxiliary device for cranes, including a coding panel 1, on which a fixed coding forming part 2 and a sequence coding forming part 3 are provided.

[0021] The coding panel 1 is made of 0.5mm thick stainless steel plate and is used to cover the surface of the equipment to be coded. It is rectangular in shape and the size is designed according to the marking area of ​​the equipment to be coded. The surface of the panel is polished to avoid paint residue and the edges are rounded to prevent scratches during operation.

[0022] The fixed coding forming part 2 includes a set of hollowed-out fixed coding font grooves 21, which are integrally formed on the panel by laser cutting process.

[0023] The serial coding forming unit 3 includes multiple serial coding windows 31, each with a rectangular cutout structure. These windows are arranged at equal intervals along the length of the inkjet panel 1, with a spacing of 10-20mm. The edges of the windows are roughened to reduce installation resistance of the coding plate 32. Each window is equipped with a coding plate 32, made of the same material as the inkjet panel 1 but larger than the serial coding window 31 to ensure complete coverage of the window edge and prevent paint from seeping in. Each coding plate 32 has a serial coding font groove 321 laser-engraved on it.

[0024] A connecting part is provided between the inkjet printing panel 1 and the coding plate 32, which is used to achieve a detachable connection between the coding plate 32 and the inkjet printing panel 1. After connection, the coding plate 32 and the inkjet printing panel 1 fit tightly, and no tools are required for disassembly and assembly. Moreover, the connection stability can be maintained even after multiple disassembly and assembly.

[0025] In this embodiment, the connecting part includes: the upper edge of the stainless steel inkjet panel 1 is folded downward to form a first slot 4; the lower edge of the stainless steel inkjet panel 1 is folded upward to form a second slot 5. The first slot 4 and the second slot 5 are parallel to each other and both extend along the length direction of the inkjet panel 1. The upper and lower edges of the coding plate 32 are respectively inserted into the first slot 4 and the second slot 5, and slide along the length direction of the inkjet panel 1.

[0026] In this embodiment, the gap of the first slot 4 is smaller than the thickness of the encoding plate 32; the gap of the second slot 5 is also smaller than the thickness of the encoding plate 32. After the encoding plate 32 is inserted into the slot, the clamping force generated by the interference fit can firmly fix the encoding plate 32 in the target position. Even if it is slightly bumped during the painting process, the encoding plate 32 will not shift, avoiding blurry coding or positional deviation. A slight interference fit is formed, allowing workers to remove or insert the encoding plate 32 from the slot without tools, simply by applying force manually, thus balancing reliable fixation and ease of operation.

[0027] In this embodiment, a magnetic adsorption layer is attached to the back of the coding panel 1. The magnetic adsorption layer is made of flexible rubber magnetic sheet. The coding panel 1 is directly adsorbed onto the surface of the metal equipment without the need for additional clamps, which facilitates quick positioning and disassembly.

[0028] In this embodiment, the front of the coding panel 1 is provided with a mother mark corresponding to the sequence coding window 31, and the coding plate 32 is provided with a child mark matching the mother mark. When the worker installs the coding plate 32, he can determine whether it is aligned by visually observing the relative position of the mother mark and the child mark. This avoids the slant and misalignment of the coding font caused by the offset of the coding plate 32. There is no need to use measuring tools such as rulers and calipers, and even novice workers can quickly master the alignment operation, reducing the rework rate caused by operational errors.

[0029] Implementation 2 The difference between this embodiment and Embodiment 1 is that the connecting part is a magnetic structure. The magnetic structure includes a first magnetic component fixed to the coding panel 1 and a second magnetic component fixed to the coding plate 32. The first and second magnetic components are matched and magnetically attracted to each other. That is, when the coding plate 32 is placed in the window, it automatically aligns and is magnetically fixed, facilitating quick replacement. To facilitate positioning of the coding plate 32, an annular positioning groove is provided on the periphery of the sequence coding window 31, and the coding plate 32 is inserted into the annular positioning groove. After the coding plate 32 is inserted into the annular positioning groove, the groove wall can restrict the displacement of the coding plate 32 in the plane, ensuring that the sequence coding font groove 321 on the coding plate 32 is completely aligned with the window, avoiding marking position errors caused by coding offset. Workers can quickly insert the coding plate 32 into the correct position without repeated adjustments, reducing operational difficulty and improving installation efficiency.

[0030] The beneficial effects of this application include: 1. By integrating the fixed coding section into a single piece and designing the serial coding section as a detachable coding plate 32, the number of coding panels 1 required to be manufactured due to the variety of equipment models is significantly reduced, saving storage space and material costs. The coding plate 32 can be quickly replaced to adapt to the needs of multiple models and batches of production, greatly improving the efficiency of coding operations.

[0031] Second, the use of detachable connection methods such as slots or magnetic attachment ensures a tight fit between the coding plate 32 and the panel, effectively preventing paint leakage, avoiding blurred markings, and improving printing quality and consistency. A magnetic adsorption layer on the back of the panel allows for quick installation onto metal equipment surfaces without clamps or adhesives, simplifying operation and preventing damage to the equipment.

[0032] Third, the visual alignment design between the parent and child markers reduces the technical requirements for operators, simplifies the installation process, reduces human error, and further improves production yield and applicability.
