Description

Technical Field

[0001] The present invention relates to the technical field of color matching of computer embroidery machines, and specifically to a control system for automatic thread distribution RFID of an embroidery machine. Background Art

[0002] Currently, the color matching of computer embroidery machines requires manual configuration. The design file designed by the designer indicates the colors to be used for each color block and outputs a production process sheet. The processor places the embroidery thread spools corresponding to the design colors on the machine and sets the color sequence steps on the interface of the computer embroidery machine according to the production process sheet.

[0003] In the prior art, the current operation is relatively cumbersome and prone to errors, resulting in a large difference between the actual embroidered product and the design. This is mainly because there are a wide variety of embroidery thread colors and multiple materials. When there are many colors in the design pattern, the color matching process is even more time-consuming. In the market scenarios of personalized customization and small order quick response, manual color matching is the most time-consuming process, and it also takes a lot of time to change the thread spools on the machine. For beginners, the corresponding relationship among the embroidery thread color, the design color, and the color displayed on the system interface will increase the difficulty of getting started. Therefore, we propose a control system for automatic thread distribution RFID of an embroidery machine to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a control system for automatic thread distribution RFID of an embroidery machine to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A control system for automatic thread distribution RFID of an embroidery machine, including an embroidery thread spool;

[0006] An RFID antenna board, which is used to activate the passive electronic tag on the embroidery thread spool and transmit the tag information of the embroidery thread spool;

[0010] An LED display board, which is used to receive the color and color code sent by the embroidery machine control system and display them through LED lights;

[0011] Furthermore, it is necessary to color-match DST or DSB format files that do not contain color sequence configurations, set the embroidery thread code numbers for each color block with the embroidery thread codes unified with the computer embroidery machine system, convert them into design files in a special format with color sequence configurations, import the design files with color sequence configurations into the computer embroidery machine, enter the color sequence configuration function interface, and the system will automatically compare the embroidery thread codes of each needle bar with the embroidery thread codes in the design file. If the match is successful, the corresponding color block will be set to the corresponding needle bar. The color blocks that cannot be matched successfully will flash, display the required embroidery thread number, and prompt the suggested needle bar to be replaced. The operator only needs to replace the required embroidery thread spool to the corresponding needle bar, and at this time, the automatic color matching is completed. In the process of embroidery, when a thread break occurs, the corresponding LED light will flash, making it easier for the operator to find the needle bar with the broken thread. In the case of multiple embroidery machines being networked, the above color matching software can be connected to all machines to obtain the information of the embroidery thread spools placed on each needle bar of each machine, automatically match which machine is most suitable for embroidering the current file according to the embroidery thread code numbers used in the design file to be embroidered currently and according to the busy or idle state of the embroidery machine, and minimize the workload of replacing embroidery threads.

[0012] Furthermore, the RFID control board is connected to the RFID antenna board to cyclically scan the antenna information of the RFID antenna board. The RFID control board has two boards, namely the main board and the slave board. The main board of the RFID control board is connected to the computer embroidery machine control system through CAN communication, and the main board of the RFID control board is connected to the LED display board through analog serial communication.

[0014] Furthermore, the embroidery thread spool is equipped with an electronic tag, and the embroidery thread spool electronic tag includes embroidery thread color, material, thread number lamp information.

[0015] Furthermore, the RFID control board includes an MCU chip, an RFID module, a radio frequency switch circuit, a CAN communication module, and an antenna interface. The MCU chip is connected to the RFID module through SPI communication, and the radio frequency switch circuit is used to obtain the signals of 10 RFID antenna boards in a polling manner.

[0016] Furthermore, the MCU chip includes U1, and U1 is GD32F103RBT6. The MCU chip is used to control the IO port switching in the radio frequency switch circuit.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] DST or DSB format files without color sequence configuration need to be color-matched. The thread code number of each color block is set with the thread code unified with the computer embroidery machine system, and then converted into a special format design file with color sequence configuration. The design file with color sequence configuration is imported into the computer embroidery machine. Entering the color sequence configuration function interface, the system will automatically compare the thread code of each needle bar with the thread code in the design file. If the match is successful, the corresponding color block will be set to the corresponding needle bar. The color blocks that cannot be successfully matched will flash, display the required thread number, and prompt the recommended needle bar to be replaced. The operator only needs to replace the required thread spool to the corresponding needle bar, and then the automatic color matching is completed. In the process of embroidery, when a thread break occurs, the corresponding LED light will flash, making it easier for the operator to find the needle bar with the broken thread. In the case of multiple embroidery machines being networked, the above color matching software can be connected to all machines to obtain the thread spool information placed on each needle bar of each machine.
