Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board production lines, and in particular to a two-dimensional code printing system and method for a gypsum board production line. Background Art

[0002] As gypsum board production lines gradually improve their intelligence and unmanned levels, QR code technology is now introduced into the gypsum board industry. By printing QR codes on gypsum boards and associating them with corresponding product information, the gypsum board information can be obtained by scanning the QR codes.

[0003] However, in actual applications, due to the high-speed and continuous production of gypsum boards, there are requirements for the time and location of printing the QR code. How to ensure that the printed QR code will not be split into two at the two-control cutter, and how to ensure that the QR code device accurately scans the QR code on each gypsum board without missing it during the high-speed movement of the gypsum board, have become technical problems that the QR code printing system needs to solve. Summary of the invention

[0004] The purpose of the present invention is to provide a two-dimensional code printing system and method for a gypsum board production line, so as to solve the technical problems in the prior art of how to ensure that the printed two-dimensional code will not be split into two at the two-control cutter, and how to ensure that the two-dimensional code device accurately scans the two-dimensional code on each gypsum board without missing it when the gypsum board moves at high speed.

[0005] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0006] A two-dimensional code printing method for a gypsum board production line, comprising:

[0007] The printing assembly is electrically connected to the cutter PLC control system of the second control section of the gypsum board production line, and the cutter PLC control system controls the cutter to cut the gypsum board and regulates the printing assembly to print the QR code on the gypsum board;

[0008] The position of the printing assembly is adjusted based on the length of the single gypsum board produced, so that the cutting position of the single gypsum board formed by the cutter always deviates from the printing position of the QR code.

[0009] As a preferred solution of the present invention, the cutter PLC control system determines the time interval between two downward movement of the cutter based on the length of a single gypsum board and the running speed of the roller;

[0010] The time interval between the two downward movement of the cutter is T(t2-t1) = the length of a single gypsum board / the running speed of the roller;

[0011] Among them, t2 is the time point when the cutter moves down to cut this time, and t1 is the time point when the cutter moves down to cut last time.

[0012] As a preferred solution of the present invention, the printing assembly has at least two printing heads, the cross-length of all the printing heads is less than the length of a single gypsum board, and the position of the printing heads is adjusted based on the length of the single gypsum board, so that the QR code printed by the printing head can evenly divide the single gypsum board into multiple equal-length blocks.

[0013] As a preferred solution of the present invention, the distance between the print head and the cutter is regulated based on the number of print heads of the printing assembly so that the distance between the cutter and the print head closest to the cutter is the same as the distance between two adjacent print heads.

[0014] As a preferred solution of the present invention, the cutter PLC control system regulates the cutter and the printing assembly to contact the gypsum board simultaneously.

[0015] In addition, the present invention also provides a printing system for a two-dimensional code printing method applied to a gypsum board production line, comprising:

[0016] A printing assembly is installed above the gypsum board production line and has at least two printing heads for printing a two-dimensional code identifying product information on the gypsum board. The installation position of the printing assembly is adjusted so that the two-dimensional code formed by the printing assembly divides the length of the gypsum board into equal parts;

[0017] A cutter assembly is installed downstream of the printing assembly and is used to cut the printed gypsum board into single gypsum boards of fixed length;

[0018] The cutter PLC control system is electrically connected to the cutter assembly and the printing assembly respectively, and is used to regulate the cutter assembly and the printing assembly to work simultaneously.

[0019] As a preferred solution of the present invention, the printing assembly is installed at the tail of the first control section of the gypsum board production line, and the cutter is installed at the head of the second control section of the gypsum board production line. By adjusting the installation position of the printing assembly, the distance between the printing head close to the cutter assembly and the cutter assembly is made the same as the distance between two adjacent printing heads of the printing assembly.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention installs a two-dimensional code printing component in the first control section of the gypsum board production line, and the printing component communicates with the cutter PLC control system of the second control section of the gypsum board production line. When the cutter of the second control section of the gypsum board production line runs to cut the board, the cutter PLC control system of the second control section of the gypsum board production line sends a signal to the printing component, and the printing component starts to print the two-dimensional code. Since the distance between the cutter device and the printing device is adjustable, and the length of the printing device is less than the length of the single gypsum board cut off, there will be no conflict between the position of the cutter cutting the gypsum board and the position of the two-dimensional code. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to more clearly illustrate the implementation methods of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for the implementation methods or the description of the prior art. Obviously, the drawings in the following description are only exemplary, and for ordinary technicians in this field, other implementation drawings can be derived from the provided drawings without creative work.

[0023] Figure 1 FIG. 4 is a flow chart of a laser boundary definition method according to an embodiment of the present invention. DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, the present invention provides a two-dimensional code printing method for a gypsum board production line, comprising the following steps:

[0026] The printing component is electrically connected to the cutter PLC control system of the second control section of the gypsum board production line. The cutter PLC control system controls the cutter to cut the gypsum board, and at the same time adjusts the printing component to print the QR code on the gypsum board, that is, the cutter PLC control system adjusts the cutter and the printing component to contact the gypsum board at the same time.

[0027] The position of the printing assembly is adjusted based on the length of the single gypsum board produced, so that the cutting position of the single gypsum board formed by the cutter always deviates from the printing position of the QR code.

[0028] The QR code is used to integrate the information of the gypsum board products, such as raw material information, manufacturer information, and usage instructions, so users can learn about the gypsum board information by scanning the QR code.

[0029] This embodiment adjusts the position of the printing head of the printing assembly based on the length of the single gypsum board that has been cut, thereby ensuring that the printed two-dimensional code is not cut at the cutting position of the cutter.

[0030] Furthermore, the cutter PLC control system determines the time interval between two downward cuts of the cutter based on the length of a single gypsum board and the running speed of the roller.

[0031] The time interval between the two downward movement of the cutter and cutting is T(t2-t1)=length of a single gypsum board / roller running speed.

[0032] Among them, t2 is the time point when the cutter moves down to cut this time, and t1 is the time point when the cutter moves down to cut last time.

[0033] In this embodiment, the cutter PLC control system automatically calculates the time point t2 when the cutter moves down to cut the gypsum board based on the time point t1 when the cutter last moved down to cut the gypsum board, thereby cutting the long gypsum board into a single gypsum board in sequence.

[0034] In this embodiment, in order to ensure that the cutting position of the cutter is always offset from the printed two-dimensional code, so that the two-dimensional code will not be cut and can be stably scanned and recognized, in this embodiment, the specific implementation method of adjusting the position of the printing component is as follows:

[0035] The printing assembly has at least two printing heads, the cross-length of all the printing heads is less than the length of a single gypsum board, and the position of the printing head is adjusted based on the length of the single gypsum board, so that the QR code printed by the printing head can evenly divide the single gypsum board into multiple equal-length blocks.

[0036] The spacing between the print heads and the cutter is regulated based on the number of print heads in the printing assembly, so that the spacing between the cutter and the print head closest to the cutter is the same as the spacing between two adjacent print heads.

[0037] On a gypsum board production line, after a specific QR code is printed on the gypsum board, the subsequent identification and partitioning and stacking of the gypsum boards is also carried out by scanning and identifying the QR code through the system to achieve specific classification and stacking. Therefore, in order to facilitate the subsequent identification of the QR code on the gypsum board production line, this embodiment adjusts the printing position of the print head so that the printing position can evenly divide a single gypsum board into multiple equal-length blocks, so that in the subsequent process of identifying the QR code, the scanning of the QR code can be driven in an isochronous interrupt manner to ensure that each QR code can be scanned. The system thus distinguishes the product information corresponding to each QR code, and can classify and stack the gypsum boards based on the scanned QR code information.

[0038] Therefore, in order to realize the recognition of QR codes in the entire gypsum board production line, the present embodiment prints the QR codes at equal intervals, that is, the distance between the printed QR codes and the beginning and end of a single gypsum board is the same, and the distance between two adjacent QR codes is the same. In other words, the QR code printed in this embodiment can divide a single gypsum board into equal-length blocks in the length direction.

[0039] The printing system corresponding to the two-dimensional code printing method of the above-mentioned gypsum board production line includes:

[0040] The printing assembly 1 is installed above the gypsum board production line and has at least two printing heads for printing a two-dimensional code identifying product information on the gypsum board. The installation position of the printing assembly 1 is adjusted so that the two-dimensional code formed by the printing assembly 1 divides the length of the gypsum board into equal parts;

[0041] The cutter assembly 2 is installed downstream of the printing assembly 1 and is used to cut the printed gypsum board into single gypsum boards of fixed length;

[0042] The cutter PLC control system is electrically connected to the cutter assembly 2 and the printing assembly 1 respectively, and is used to regulate the cutter assembly 2 and the printing assembly 1 to work simultaneously.

[0043] The printing assembly 1 is installed at the tail end of the first control section of the gypsum board production line, and the cutter assembly 2 is installed at the head end of the second control section of the gypsum board production line. By adjusting the installation position of the printing assembly 1, the distance between the printing head close to the cutter assembly 2 and the cutter assembly 2 is made the same as the distance between the two adjacent printing heads of the printing assembly 1.

[0044] In this embodiment, a QR code printing component 1 is installed in the first control section of the gypsum board production line, and the printing component 1 communicates with the cutter PLC control system of the second control section of the gypsum board production line. When the cutter of the second control section of the gypsum board production line is running to cut the board, the cutter PLC control system of the second control section of the gypsum board production line sends a signal to the printing component 1, and the printing component 1 starts to print the QR code. Since the distance between the cutter component 2 and the printing component 1 can be adjusted, and the QR code is evenly and equidistantly printed on the single gypsum board cut off, there will be no conflict between the position of the cutter cutting the gypsum board and the position of the QR code.

[0045] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
