Description

Technical Field

[0001] This invention relates to an embroidery visual printing all-in-one machine and its working method. Background Technology

[0002] The embroidery unit is a specialized mechanical device for automatically embroidering fabric patterns. Among them, the computerized embroidery unit relies on digital control technology to complete embroidery operations with high efficiency and high precision. During the embroidery process, the colorful patterns on the fabric are often composed of patterns of various colors and shapes. Currently, embroidery products mainly use two processing methods to achieve multi-color pattern effects.

[0003] The first method relies on the embroidery unit itself to switch between multiple colors of embroidery thread to achieve a colored embroidery effect. This mode requires the equipment to frequently change embroidery threads of different colors, placing high demands on the structure of the embroidery unit head and the control system. In actual production, several shortcomings have been revealed: First, achieving colored embroidery requires a large number of different colored embroidery threads, resulting in a complex embroidery unit head structure and high equipment manufacturing costs; second, the frequent switching of embroidery threads and heads during processing is cumbersome and directly reduces production efficiency; third, the preparation of pattern files for multi-color embroidery is difficult, requiring high levels of professional skills and practical experience from operators, necessitating long-term training to become competent.

[0004] The second method employs a process separation approach, using relatively simplified embroidery units. The basic pattern is embroidered with a single-color thread, and the semi-finished fabric is then transferred to an independent printer for color printing, resulting in a colored pattern. This method reduces the complexity of the embroidery unit itself, but the fabric is prone to stretching, displacement, and deformation when transferred from the embroidery station to the printing station. Even with subsequent repositioning and calibration, it is difficult to completely replicate the relative positional state at the time of embroidery completion, easily leading to defects such as misalignment between the printed pattern and the embroidery outline, and inconsistent pattern matching, severely affecting the quality of the finished product.

[0005] In summary, existing processes for processing colored embroidered fabrics either involve complex equipment structures and low production efficiency, or are prone to positioning deviations during process flow, making it difficult to guarantee product yield. Therefore, it is necessary to propose an embroidery visual printing integrated machine to solve the problems in the existing embroidery production process. Summary of the Invention

The embroidery frame assembly moves in the X and Y directions at the upper end of the machine table. The embroidery unit uses single-color or multi-color embroidery thread for embroidery.

[0009] Preferably, the printing unit includes a printing carriage, a printhead, and a printhead cleaning station. The printhead is mounted on the printing carriage and moves with the printing carriage in the X and Z directions.

[0010] Preferably, when the printing carriage is about to enter the printing area, the printing carriage first raises the printhead along the Z-axis, and after entering the printing area, the printhead lowers to the printing height; after printing is completed, the printing carriage raises the printhead again along the Z-axis, and after leaving the printing area, it resets and returns to the printhead cleaning station.

[0011] Preferably, the vision unit includes a support, a light source, and an optical camera, with the light source and optical camera mounted on the support; the optical camera acquires fabric image information and transmits the image information to the embroidery vision printing management system.

[0012] Preferably, the printing carriage includes a back plate, a printhead lifting plate, and a motor. The output end of the motor is connected to a coupling, one end of which is connected to a lead screw. A nut is connected to the lead screw, and the nut is installed on the printhead lifting plate. The motor drives the nut and the printhead lifting plate to move up and down through the coupling and lead screw. The lower end of the printhead lifting plate is provided with a printhead mounting plate, and the printhead is installed on the printhead mounting plate.

The mover and the stator drive the back plate to move along the X-direction guide rail.

[0014] Preferably, sensor mounting plates are provided at both ends of the X-direction guide rail, a photoelectric sensor is provided on the sensor mounting plate, and a sensing plate is provided on the back plate to cooperate with the photoelectric sensor.

[0015] Preferably, the back plate is equipped with a motor mounting base and a bearing housing 2. The motor is mounted on the motor mounting base, and the motor mounting base is provided with a bearing housing 1. The lead screw is mounted on the bearing housing 1 and the bearing housing 2.

[0016] Preferably, the nozzle lifting plate is provided with a photoelectric sensor two and a micro switch, and the bearing seat two is provided with a sensing plate two that cooperates with the photoelectric sensor two and the micro switch.

[0017] A method for operating an embroidery visual printing all-in-one machine includes the following steps: 1) The embroidery frame component is used to position the fabric at the embroidery station; 2) Subsequently, the fabric is embroidered under the action of the embroidery machine head assembly and embroidery frame assembly; 3) Once the embroidery is complete, move the embroidery frame component to the printing origin; 4) Acquire image information of the fabric using an optical camera; 5) Compare the image information with the standard template to determine the position, size, shape, and orientation of the image for printing, and generate the final print image file; 6) The printing unit prints the final image file onto the fabric; 7) Printing is finished, the printhead is reset, and the fabric is removed.

[0018] Preferably, after printing is completed, when the fabric needs to be embroidered a second time, the embroidery frame component returns to the embroidery station to continue embroidery. Once the embroidery is completed, the entire process ends.

[0019] The beneficial effects of this invention are: 1. This invention integrates the embroidery unit, printing unit and vision unit into a single machine structure. The fabric does not need to be disassembled and transferred between different devices. Embroidery and printing composite processing can be completed on the same machine. This avoids the problems of stretching deformation and positional displacement that occur when semi-finished fabrics are transferred across devices. It prevents the printed pattern from misaligning with the outline of the embroidery base from the root, and effectively improves the alignment accuracy of the finished pattern and the product processing yield.

[0020] 2. The embroidery unit uses a single color embroidery thread to complete the base embroidery, eliminating the need for multiple sets of color-changing embroidery threads and complex thread-changing mechanisms. This simplifies the embroidery machine head structure and reduces equipment hardware costs. At the same time, it eliminates the need for frequent thread changes and embroidery head switching during processing, reducing process waiting time, improving overall production efficiency, and also reducing the difficulty of creating embroidery pattern files, thus lowering the experience and skill threshold for operators.

[0021] 3. Equipped with a vision unit, the actual image of the fabric is captured by an optical camera and compared with a standard template to complete the coordinate positioning. This enables visual calibration and positioning of the embroidery and printing processes, ensuring the matching degree of the embroidery path and the position of the printed pattern. Even if there is slight deformation of the fabric, the processing coordinates can be corrected through visual recognition, further improving the processing accuracy.

[0022] 4. This equipment supports multi-mode cyclic processing of embroidery and printing. It can realize various alternating operation processes such as embroidery-printing, embroidery-printing-embroidery, and printing-embroidery-printing according to process requirements. It can embroider first and then print, or realize multi-layer composite processes of alternating embroidery and printing. It is suitable for more customized processing needs of fabric patterns and handicrafts, and the equipment has strong versatility.

[0023] 5. The printing unit uses a linear motor to drive the printhead to move in the X direction, and a screw drive mechanism to lift the printhead in the Z direction. Multiple photoelectric sensors and microswitches are used to complete the travel limit. With the help of the printhead cleaning station, the printhead movement is stable and reliable, and precise printing and coloring can be achieved. The whole machine is controlled by the embroidery vision printing management system. The embroidery, vision acquisition and printing processes are coordinated and orderly, with a high degree of automation.

[0024] 6. The motor and lead screw configuration of this application enables the nozzle to move up and down in the Z direction while overcoming the obstruction formed by the embroidery frame assembly on the nozzle's planar movement path, preventing nozzle collisions and ensuring the normal operation of the nozzle.

[0046] Furthermore, in a working method of an embroidery visual printing all-in-one machine, after printing is completed, when the fabric needs to be embroidered a second time, the embroidery frame component returns to the embroidery station to continue embroidery.

[0050] Furthermore, when fabric embroidery or printing processes require it, the embroidery visual printing management system can execute a print-embroidery-print-embroidery-print procedure.

[0051] Furthermore, when fabric embroidery or printing processes require it, the embroidery visual printing management system can execute the embroidery-printing-embroidery process.

[0052] The mover and stator of this invention are representations of a linear motor transmission mechanism, and therefore will not be described in detail here.

[0053] The working principle of the embroidery unit of this invention is similar to that of embroidery machines on the market, so it will not be described in detail.

[0054] Furthermore, the movement of the embroidery frame components is a standard technique for existing embroidery, so it will not be described in detail.

[0055] When this invention is implemented, it is also equipped with an industrial control computer, a display terminal, etc., which are mainly used for program editing, adjustment and control, displaying the working status of the equipment, recording the equipment operation data, etc., so as to ensure the stability of the equipment.

[0056] The embroidery visual printing management system of the present invention is the control unit of the equipment and executes the operating program of the equipment.

[0057] The above implementation scheme is applicable to the processing of ordinary fabrics that are embroidered first and then printed. The outline base is embroidered with single-color embroidery thread, and then the colored pattern is filled in by digital printing. The fabric is fixed in the embroidery frame assembly throughout the process and does not leave the equipment, so there will be no transfer or displacement. The coordinates are corrected by visual positioning, and the alignment accuracy between the printed pattern and the embroidery outline is high. The machine head can be greatly simplified, the equipment cost is lower, the plate making difficulty is reduced, and the production efficiency is improved.

[0058] Example 2: The hardware structure is completely identical to Example 1, the difference being that the processing technology involves alternating embroidery and printing. Some handicraft fabrics require multi-layered composite effects, necessitating secondary embroidery. The processing steps are as follows: 1) The fabric is fixed in the embroidery station using the embroidery frame assembly; 2) Subsequently, the fabric is embroidered under the action of the embroidery machine head assembly and embroidery frame assembly; 3) Once the embroidery is complete, the embroidery frame component is corrected and moved to the printing origin; 4) Acquire image information of the fabric using an optical camera; 5) Compare the image information with the standard template to determine the position, size, shape, and orientation of the image for printing, and generate the final print image file; 6) The printing unit prints the final image file onto the fabric, completing the printing process; 7) Without removing the fabric, repeat step 2) to complete the second embroidery; once the embroidery is complete, remove the fabric.

[0059] The above operations can be performed by selecting the embroidery-recognition-printing-embroidery mode in the embroidery visual printing management system according to the product's process requirements. For example, when processing three-dimensional embroidered decorative fabrics: first, embroider the underlying texture, print the first layer of color, and then continue to embroider raised decorative parts (such as sequins, beads, etc.) or embroidery threads such as gold and silver threads that cannot be printed on the already printed fabric; the entire cycle is completed within the same machine. Each round of processing will re-capture images and correct coordinates through an optical camera. Even if the fabric undergoes slight stretching and deformation after multiple processing steps, position compensation will be performed at each step, and multi-layered patterns can still be accurately aligned, meeting the processing needs of complex composite patterns for customized handicrafts.

[0060] Example 3: See Figure 7 As shown, to meet the needs of fabric embroidery or improve embroidery efficiency, multiple embroidery head components are set up, and the other hardware structures are completely consistent with Embodiment 1. For the processing of thin and easily deformable fabrics, slight local stretching is likely to occur after the fabric is clamped. The embroidery heads of the multi-head embroidery machine are designed with a set spacing, but during manufacturing, there will inevitably be errors in the distance between the multiple embroidery heads, and the fabric will also deform after embroidery. As a result, the embroidered pattern is not in the theoretically designed position. Therefore, the pattern embroidered by the multi-head embroidery machine cannot be directly copied to the designed position for printing. Instead, visual recognition is required to find the accurate position and shape of the pattern embroidered by different embroidery heads, then the image is processed, and then the processed image is copied to the position specified by visual recognition before printing.

[0061] Example 4: The hardware structure is completely consistent with Example 1. When the fabric is lace, it has its own pattern, and traditional embroidery units are difficult to position, relying purely on manual operation; however, the vision unit of this application can easily identify and position it. In the embroidery vision printing management system, the vision-embroidery or vision-printing-embroidery mode can be selected.

[0062] Example 5: See Figure 8 As shown, the printing unit and the embroidery head assembly are placed on both sides of the crossbeam, which increases the activity area of ​​the printing unit and facilitates the setting of the embroidery head assembly, making it easier for the all-in-one machine to complete the embroidery and printing work on a larger area of ​​fabric.

[0063] The working principle of each component of this invention is as follows: 1. Visual Positioning Working Principle: After the fabric is clamped and fixed on the embroidery frame assembly, the optical camera in the vision unit acquires the actual image of the fabric with the assistance of a light source, and transmits the image information to the embroidery visual printing management system. The system compares the fabric image acquired on-site with the internally stored standard template, identifies the actual position of the fabric and slight stretching deformation, corrects for true and effective embroidery processing coordinates and images for printing, eliminates positioning errors caused by fabric clamping deformation, and outputs coordinate commands to the embroidery unit and printing unit, achieving visual-assisted precise positioning.

[0064] 2. Embroidery unit working principle: The embroidery unit uses single-color embroidery thread to embroider the base outline; after receiving the embroidery path and coordinate instructions issued by the system, the embroidery frame component moves in the X and Y directions above the machine table, and the embroidery head component cooperates with the displacement of the embroidery frame to complete the embroidery operation of the outline base on the fabric.

[0065] 3. Printing unit movement and printing working principle: The printing unit is mounted on a crossbeam, and the printhead has the ability to move horizontally in the X direction and vertically in the Z direction. X-direction movement: The stator of a linear motor is set on the crossbeam, and a matching mover is configured on the back plate of the printing assembly. The interaction between the mover and the stator drives the back plate and the entire printing assembly to move laterally along the X-direction guide rail.

[0066] Z-axis lifting: The motor on the back plate drives the lead screw to rotate via a coupling. The lead screw drives the nut and the printhead lifting plate to slide up and down along the Z-axis guide rail, thereby driving the printhead to complete the lifting action. The printhead descends to the correct position to perform the printing job; when the printhead is raised, it can avoid the embroidery frame assembly to prevent collision.

[0067] When the embroidery frame moves to the printing origin, the system outputs the corrected print image. The print head moves in the X direction and rises and falls in the Z direction in coordination to print the color pattern on the already embroidered fabric base.

[0068] 4. Working Principle of Whole Machine Linkage Control: The embroidery vision printing management system serves as the core of the whole machine control, unifying and coordinating the timing actions of the vision unit, embroidery unit, and printing unit. Basic processing flow logic: Fabric clamping → Embroidery unit embroidery → Vision image acquisition and coordinate calibration → Embroidery frame returns to printing origin → Printing unit printing → Printer head reset and part removal.

[0069] If the process requires multi-layer composite processing, the system can cyclically call the "embroidery-return to printing origin-visual acquisition and comparison positioning-printing" process to realize alternating embroidery-printing-embroidery, embroidery-printing, and other embroidery-printing processes. Before each round of processing, the vision unit will re-acquire the fabric image and correct the coordinates to compensate for the deformation caused by multiple processing of the fabric and ensure accurate matching of the pattern position.

[0070] The overall technical advantages of this invention are: the fabric is fixed in the embroidery frame assembly throughout the process, eliminating the need for disassembly and transfer between the embroidery and printing equipment, thus avoiding misalignment of embroidery and printing caused by fabric stretching and displacement during transfer; combined with visual recognition to correct processing coordinates in real time, further offsetting the minor deformations caused by fabric clamping and processing; the embroidery unit uses a single-color embroidery thread as a base, reducing the complexity of the machine head structure, and in conjunction with the automated linkage of the whole machine, it balances processing accuracy, production efficiency and equipment cost.

[0071] According to actual needs, this invention can set up multiple sets of visual units and multiple optical cameras to collect image information. The embroidery visual printing management system (equipped with corresponding processing software) can crop and stitch the images and select the effective parts for use.

[0072] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
