Description

Technical Field

[0001] This application relates to the technical field of pipeline production, and in particular to a fully automatic inkjet printing device. Background Technology

[0002] In industrial production, clear and accurate product labeling is crucial. Coding equipment, as a key tool for product labeling, plays a vital role in improving production efficiency and product quality through technological advancements. With the continuous improvement of industrial automation, higher demands are being placed on the automation, intelligence, and processing accuracy of coding equipment. Coding equipment is widely used in various manufacturing industries, such as food, beverage, pharmaceuticals, and building materials. It can quickly and accurately print important information such as production dates, batch numbers, and QR codes on product surfaces, facilitating product traceability and management and promoting the modernization of production processes across industries.

[0003] In traditional coding operations, to ensure coding effectiveness, the surface of the workpiece is usually derusted first to ensure the coding adheres firmly. Rust removal often involves manual sanding with sandpaper or wire brushes, a labor-intensive and time-consuming method that is both physically demanding and inefficient. Sandblasting is another method, using high-pressure airflow to propel abrasive particles onto the workpiece surface, removing the rust layer through impact. However, this method generates significant dust, severely polluting the working environment, and subsequent cleaning is tedious. Traditional coding operations often use semi-automatic coding machines, requiring manual placement of the workpiece in a designated position before coding. This process is prone to inaccurate positioning and inconsistent coding quality, failing to meet the demands of large-scale, high-efficiency production.

[0004] However, existing rust removal and marking methods have significant drawbacks. Manual rust removal and semi-automatic marking are not only inefficient and difficult to adapt to the pace of large-scale industrial production, but manual operation is also prone to errors, leading to incomplete rust removal and inaccurate marking positions, affecting the product's appearance and quality. While sandblasting can improve rust removal efficiency to some extent, it causes environmental pollution and cleaning difficulties, increasing production costs and management complexity. Utility Model Content

[0005] To address the issues of low processing efficiency and poor quality stability caused by the separation of coding and rust removal processes in traditional coding equipment.

[0006] This application provides a fully automatic inkjet printing device, which adopts the following technical solution: A fully automatic inkjet printing device includes a control module, a gantry frame, a rust removal component, a coding component, and a workpiece support mechanism for carrying the workpiece to be processed; the rust removal component and the coding component are both reciprocally mounted on the main beam of the gantry frame along the length direction of the gantry frame, and the coding component is located downstream of the rust removal component; the control module is electrically connected to the rust removal component and the coding component respectively.

[0007] By adopting the above technical solution, in actual production, when the workpiece to be processed is transported to the work area via the workpiece support mechanism, the control module can first drive the rust removal component to move along the gantry and pre-treat the surface of the workpiece. Subsequently, the marking component located downstream follows along the same track to complete the marking operation, realizing the automated continuous flow of the rust removal-marking process. The integrated track design of the moving component along the gantry avoids synchronization errors caused by independent driving of multiple mechanisms, ensuring that marking is completed immediately in the optimal state after rust removal of the workpiece surface, effectively improving the adhesion and clarity of the marking. In addition, when processing workpieces of different lengths and specifications, only the moving stroke of the two mechanisms needs to be adjusted through the control module to adapt, without the need to change tooling fixtures, significantly enhancing the versatility and production flexibility of the equipment.

[0008] Preferably, it also includes a drive mechanism, which includes a drive motor and a lead screw fixedly connected to the output end of the drive motor. The lead screw is installed along the length direction of the main beam of the gantry frame. A guide slide rod parallel to the lead screw is also installed on the main beam of the gantry frame. The rust removal component and the marking component are both threadedly connected to the lead screw and slidably connected to the guide slide rod. The drive motor is electrically connected to the control module.

[0009] By adopting the above technical solution, the fully automatic marking equipment can realize the reciprocating movement of the rust removal component and the marking component along the length of the gantry main beam through the drive mechanism. The control module can control the drive motor to work, and the drive motor drives the lead screw to rotate, so that the rust removal component and the marking component, which are threadedly connected to the lead screw and slidably connected to the guide slide, move along the length of the gantry main beam. This realizes the automated reciprocating movement of the rust removal component and the marking component on the gantry main beam, and can perform rust removal and marking operations on different positions of the workpiece to be processed.

[0010] Preferably, the rust removal component and the marking component are spaced apart on the main beam of the gantry.

[0011] By adopting the above technical solution, the rust removal component and the marking component are kept at a certain distance on the main beam of the gantry frame, so as to avoid mutual interference between the two during operation, ensure stable operation of the equipment, and improve the accuracy and efficiency of rust removal and marking operations.

[0012] Preferably, the rust removal assembly includes a first sliding block that cooperates with the lead screw and guide slide, a first support rod fixed on the first sliding block, a rust removal brush head fixed on the first support rod, a rust removal motor that drives the rust removal brush head to rotate, and an adjusting cylinder for adjusting the distance between the rust removal brush head and the workpiece to be treated. The rust removal motor and the adjusting cylinder are both electrically connected to the control module.

[0013] By adopting the above technical solution, the control module can control the rust removal motor to drive the rust removal brush head to rotate for rust removal. At the same time, it can control the adjusting cylinder to adjust the distance between the rust removal brush head and the workpiece to be treated, so that the rust removal work can be flexibly adjusted according to the actual situation. The screw and guide slide can move the rust removal component along the length of the gantry main beam to remove rust from the workpiece to be treated at different positions. The gantry, rust removal component, marking component and workpiece support mechanism can work together to complete the rust removal and marking work of the workpiece to be treated.

[0014] Preferably, the rust removal assembly further includes a blowing nozzle fixed on the first support rod, an air pump that provides an air source, and a solenoid valve that controls the air flow. The blowing nozzle is positioned facing the surface of the workpiece to be treated and is located downstream of the working side of the rust removal brush head. The air pump and the solenoid valve are both electrically connected to the control module.

[0015] By adopting the above technical solution, the blowing nozzle, air pump and solenoid valve work together to provide air source through the air pump after the rust removal brush head removes rust. The control module controls the opening and closing of the solenoid valve so that the blowing nozzle blows air onto the surface of the workpiece to be treated, blowing away the rust residue and other impurities generated during rust removal, ensuring that the surface of the workpiece to be treated is clean, and providing good conditions for subsequent coding.

[0016] Preferably, the first support rod includes a first inner rod and a first outer rod. The first outer rod is slidably sleeved on the outer periphery of the first inner rod. The blowing nozzle is installed at one end of the first inner rod extending out of the first outer rod. A first control cylinder is installed in the first outer rod. The piston rod of the first control cylinder is fixed to one end of the first inner rod that extends into the first outer rod. The rust removal brush head, rust removal motor, and adjusting cylinder are installed on the outer wall of the first outer rod. The first control cylinder, rust removal motor, and adjusting cylinder are all electrically connected to the control module.

[0017] By adopting the above technical solution, the first inner rod can slide inside the first outer rod. The first control cylinder controls the extension or retraction of the first inner rod, which can flexibly adjust the position of the blowing nozzle to adapt to workpieces of different sizes and shapes. This allows the blowing nozzle to better face the surface of the workpiece, effectively removing rust residue and other impurities generated during the rust removal process. This provides a clean surface for subsequent coding operations, improving coding quality and effect. At the same time, the fixed connection between the first outer rod and the first sliding block ensures the structural stability of the entire rust removal assembly during movement. The electrical connection between the first control cylinder and the control module enables automated adjustment of the blowing position, further enhancing the equipment's adaptability to complex workpieces.

[0018] Preferably, the coding assembly includes a second sliding block that cooperates with the lead screw and guide slide, a second support rod fixed on the second sliding block, and a coding terminal fixed on the second support rod, wherein the coding terminal is electrically connected to the control module.

[0019] By adopting the above technical solution, the marking component, through the cooperation of the second sliding block, lead screw, and guide slide rod, achieves stable movement along the length of the gantry main beam. The control module can control the working state of the marking wrench according to a preset program or real-time signals such as the speed of the drive motor. When the workpiece to be processed after rust removal by the control module moves to the marking area, the marking wrench can accurately complete the marking operation on the surface of the workpiece. The second support rod provides stable support for the marking wrench, ensuring that the marking wrench maintains a stable relative position with the workpiece surface during movement, thereby ensuring the clarity and positional accuracy of the marking.

[0020] Preferably, the second support rod includes a second outer rod and a second inner rod. The second outer rod is slidably sleeved on the outer periphery of the second inner rod. The jack is installed at one end of the second inner rod extending out of the second outer rod. A second control cylinder is installed in the second outer rod. The piston rod of the second control cylinder is fixed to one end of the second inner rod that extends into the second outer rod. The second control cylinder is electrically connected to the control module.

[0021] By adopting the above technical solution, the second outer rod is slidably sleeved on the outer periphery of the second inner rod, and the piston rod of the second control cylinder is fixed at one end inside the second outer rod. The control module can control the second control cylinder to drive the second inner rod to slide inside the second outer rod, thereby facilitating the adjustment of the distance between the marking terminal and the workpiece to be processed, so as to adapt to the marking operation of workpieces of different heights or sizes, and improve the versatility and applicability of the equipment.

[0022] Preferably, the workpiece support mechanism includes a frame, and at least two V-shaped positioning blocks are provided below the main beam of the gantry frame. The V-shaped positioning blocks are arranged along the length of the main beam of the gantry frame, and photoelectric sensors electrically connected to the control module are provided next to the V-shaped positioning blocks.

[0023] By adopting the above technical solution, the V-shaped positioning block can accurately position and support workpieces of different shapes and sizes, ensuring their stability during rust removal and marking processes. Its arrangement along the length of the gantry main beam better adapts to the equipment's workflow. Meanwhile, the photoelectric sensor next to the V-shaped positioning block can detect the position and status information of the workpiece in real time and feed this information back to the control module. This allows the control module to precisely control the operation of the rust removal and marking components, improving the equipment's automation level and work efficiency, and ensuring accurate marking positioning.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The rust removal component and the coding component are integrated into the fully automatic coding equipment, which enables the rust removal and coding operations to be carried out in a continuous manner, reducing the handling and waiting time of the workpieces to be processed between different processes, improving production efficiency. Moreover, the coding component is located downstream of the rust removal component, so the workpieces to be processed are rusted first and then coded, which improves the quality of the identification code. 2. The control module is electrically connected to the rust removal component and the marking component respectively to realize automated control, reduce manual intervention and adjustment, and ensure the consistency of rust removal and marking quality; 3. The marking component is equipped with a position sensor to detect the marking position of the workpiece to be processed and feed it back to the control module, thereby improving positioning accuracy and operational flexibility and meeting the production needs with high requirements for marking position and quality.

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 This application will be described in further detail.

[0028] This application discloses a fully automatic inkjet printing device.

[0029] Reference Figure 1 and Figure 2 A fully automatic inkjet printing device includes a control module 2, a gantry frame 1, a rust removal component 3, a coding component 4, a workpiece support mechanism 5, and a drive mechanism 6. The drive mechanism 6 can drive the rust removal component 3 and the coding component 4 to reciprocate along the length of the gantry frame 1, with the coding component 4 located downstream of the rust removal component 3. The control module 2 is electrically connected to the rust removal component 3, the coding component 4, and the drive mechanism 6. This configuration enables the device to automatically complete the rust removal and coding operations on the workpiece, improving production efficiency and quality consistency.

[0030] Reference Figure 1 A drive mechanism 6 is installed on the gantry frame 1. The drive mechanism 6 includes a drive motor 61, a lead screw 62, and a guide slide rod 63. One end of the lead screw 62 is fixedly connected to the output end of the drive motor 61 and installed along the length of the main beam of the gantry frame 1. The other end of the lead screw 62 is rotatably installed on the gantry frame 1. The guide slide rod 63 is fixedly installed along the length of the main beam of the gantry frame 1 and is arranged parallel to the lead screw 62. The rust removal component 3 and the marking component 4 are both threadedly connected to the lead screw 62 and slidably connected to the guide slide rod 63. The drive motor 61 is electrically connected to the control module 2. Under the command of block 2, drive motor 61 drives lead screw 62 to rotate, thereby driving rust removal component 3 and marking component 4 to slide along the length of lead screw 62 under the limit of guide slide rod 63, so as to realize rust removal and marking of workpiece to be processed. At the same time, marking component 4 is located downstream of rust removal component 3 to ensure that the marking part of workpiece to be processed is derusted first when marking workpiece to be processed, so as to improve marking quality. Rust removal component 3 and marking component 4 are spaced apart on the main beam to avoid mutual interference during operation and further ensure marking quality.

[0031] Reference Figure 1The rust removal component 3 includes a first sliding block that cooperates with the lead screw 62 and the guide slide rod 63. A first support rod 32 is fixed on the first sliding block. A rust removal brush head 33, a rust removal motor 34 that drives the rust removal brush head 33 to rotate, and an adjusting cylinder 35 for adjusting the distance between the rust removal brush head 33 and the workpiece to be treated are installed on the first support rod 32. The rust removal motor 34 and the adjusting cylinder 35 are both electrically connected to the control module 2. The control module 2 can adjust the distance between the rust removal brush head 33 and the workpiece to be treated according to the size of the workpiece to be treated by adjusting the adjusting cylinder 35, and control the rust removal motor 34 to drive the rust removal brush head 33 to rotate to remove rust from the workpiece to be treated. In addition, the rust removal assembly 3 also includes a blowing nozzle 36 fixed on the first support rod 32, an air pump 37 that provides an air source, and a solenoid valve 38 that controls the air flow. The blowing nozzle 36 faces the surface of the workpiece to be treated and is located downstream of the working rust removal brush head 33. The air pump 37 and the solenoid valve 38 are both electrically connected to the control module 2. While the rust removal brush head 33 rotates to remove rust from the workpiece to be treated, the control module 2 controls the solenoid valve 38 to open. The high-pressure gas provided by the air pump 37 is sprayed out through the blowing nozzle 36 to remove rust residue from the surface of the workpiece to be treated, ensuring the quality of subsequent coding.

[0032] Reference Figure 2 To broaden its applicability, the first support rod 32 adopts a telescopic structure. The first support rod 32 includes a first inner rod 322 and a first outer rod 321. The first outer rod 321 is slidably sleeved around the outer periphery of the first inner rod 322. A blowing nozzle 36 is installed at one end of the first inner rod 322 extending out of the first outer rod 321. A first control cylinder 39 is installed inside the first outer rod 321. The piston rod of the first control cylinder 39 is fixed to one end of the first inner rod 322 that extends into the outer rod. The first control cylinder 39 is also connected to the control module 2. Electrically connected, the control module 2 can control the first control cylinder 39 to drive the first inner rod 322 to extend and retract relative to the first outer rod 321, thereby adjusting the position of the blowing nozzle 36 to adapt to the blowing needs of workpieces of different sizes; the rust removal brush head 33, the rust removal motor 34 and the adjusting cylinder 35 are installed on the outer wall of the first outer rod 321. The rust removal motor 34 and the adjusting cylinder 35 are both electrically connected to the control module 2. The height of the rust removal brush head 33 can be adjusted by adjusting the adjusting cylinder 35 to adapt to the rust removal needs of workpieces of different sizes.

[0033] Reference Figure 2The marking component 4 includes a second slider, a second support rod 42, and a marking terminal 43. The second slider cooperates with the lead screw 62 and the guide slide rod 63. The second support rod 42 is fixed on the second sliding block 41. The marking terminal 43 is installed on the second support rod 42 and is electrically connected to the control module 2. When marking the workpiece to be processed, the control module 2 sends a command to the marking terminal 43 to control the marking. In practical applications, the operator first stores data such as the size of the workpiece to be marked and the interval between two marks in the control module 2. The control module 2 determines the current position of the marking component 4 based on the rotation speed of the drive motor 61, thereby completing the control of marking the workpiece to be processed. To accommodate more sizes... For marking requirements of the workpiece to be processed, the second support rod 42 is also a telescopic structure. The second support rod 42 includes a second outer rod 421 and a second inner rod 422. The second outer rod 421 is slidably sleeved on the outer periphery of the second inner rod 422. The marking head 43 is installed at one end of the second inner rod 422 that extends out of the second outer rod 421. A second control cylinder 44 is installed inside the second outer rod 421. The piston rod of the second control cylinder 44 is fixed to one end of the second inner rod 422 that extends into the outer rod. The second control cylinder 44 is electrically connected to the control module 2. The control module 2 can control the second control cylinder 44 to drive the second inner rod 422 to extend and retract relative to the outer rod, thereby adjusting the height of the marking head 43 to adapt to the marking requirements of workpieces of different sizes.

[0034] Reference Figure 1 and Figure 2 The workpiece support mechanism 5 includes a frame 51. At least two V-shaped positioning blocks are provided on the frame 51 below the main beam of the gantry frame 1. The V-shaped positioning blocks are arranged along the length of the main beam to stably support the cylindrical workpiece waiting to be processed. A photoelectric sensor 53 electrically connected to the control module 2 is provided next to the V-shaped positioning block. When the workpiece to be processed is placed on the positioning block, the photoelectric sensor 53 detects the workpiece to be processed and sends a signal to the control module 2 to trigger the subsequent rust removal and marking operations.

[0035] The implementation principle of this embodiment is as follows: The workpiece to be processed is transferred to the V-shaped positioning block of the workpiece support mechanism 5. After the photoelectric sensor 53 detects the workpiece, it transmits the signal to the control module 2. The control module 2 then starts the drive motor 61, which drives the lead screw 62 to rotate, causing the rust removal component 3 and the marking component 4 to move along the guide slide 63 toward the workpiece. When the rust removal component 3 moves to the preset position above the workpiece, the control module 2 controls the adjustment cylinder 35 to adjust the distance between the rust removal brush head 33 and the surface of the workpiece to a suitable range according to the pre-stored workpiece size data. Then, the rust removal motor 34 is started to drive the rust removal brush head 33 to rotate at high speed to remove rust from the workpiece surface. At the same time, the control module 2 controls the solenoid valve 38 to open, and the high-pressure gas generated by the air pump 37 is continuously sprayed out through the blowing nozzle 36. Under the real-time control of the first control cylinder 39, the extension length of the blowing nozzle 36 is finely adjusted according to the curvature of the workpiece surface to always maintain the best blowing angle, so as to blow away the rust powder and debris generated during the rust removal process from the workpiece surface in time, ensuring that the rust removal area is clean.

[0036] While the rust removal component 3 completes the rust removal operation on the designated area of ​​the workpiece, the drive mechanism 6 continues to drive the rust removal component 3 and the coding component 4 to move. When the coding component 4 moves above the rust-removed area, the control module 2 determines the current position of the coding component 4 according to a preset program or real-time signals such as the rotation speed of the drive motor 61. When the coding component 4 moves to the preset coding position, the control module 2 controls the second control cylinder 44 to work, pushing the second inner rod 422 to extend, so that the coding dock 43 descends to the preset coding height with the workpiece surface. Subsequently, under the instruction of the control module 2, the coding dock 43 accurately sprays codes on the clean workpiece surface according to the preset coding pattern and character sequence. After the current workpiece is processed, all mechanisms reset, that is, the rust removal component 3 and the coding component 4 move to the initial position, waiting for the processing of the next workpiece, to ensure that when the next workpiece is processed, the coding component 4 is still downstream of the working position of the rust removal component 3.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
