Description

Technical Field

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

[0002] In the entire gypsum board production line, a QR code is first printed on the surface of the produced gypsum board. The QR code information includes various information such as composition information, manufacturer information, and usage information. In order to ensure that all QR codes are included on a single gypsum board when the gypsum board is cut, the distance between two adjacent QR codes and the distance between the outermost QR code and the cutter assembly are set to be equal.

[0003] After the continuous gypsum boards are cut by a cutter, the gypsum boards will enter the subsequent process section at a uniform speed. The existing method of classifying and conveying the cut gypsum boards does not combine the QR code information with the classified conveying, resulting in a relatively complicated implementation method of the classified conveying. Summary of the invention

[0004] The purpose of the present invention is to provide a two-dimensional code recognition and classification system and method for a gypsum board production line, so as to solve the technical problem that the two-dimensional code information is not combined with the classification and transportation in the prior art, resulting in a relatively complicated implementation method of the classification and transportation.

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

[0006] A two-dimensional code recognition and classification system for a gypsum board production line, comprising:

[0007] A QR code scanning camera, which is used to identify information of all QR codes on a cut single gypsum board;

[0008] a photoelectric sensor installed at the position of the two-dimensional code scanning camera, the photoelectric sensor being used to detect the gypsum board transmitted to the position of the two-dimensional code scanning camera;

[0009] A control system is connected to the two-dimensional code scanning camera and the photoelectric sensor. An interrupt signal sending module is provided in the control system. The control system regulates the operation of the two-dimensional code scanning camera based on the detection result of the photoelectric sensor. The control system calculates the interrupt time point of the two-dimensional code scanning camera, and uses the interrupt signal sending module to send an interrupt signal to the two-dimensional code scanning camera at the interrupt time point, so that the control system sequentially receives the two-dimensional code information scanned by the two-dimensional code scanning camera and classifies the gypsum board based on the two-dimensional code information.

[0010] As a preferred embodiment of the present invention, the number of two-dimensional codes printed on the surface of a single gypsum board is at least two, and the two-dimensional codes are evenly distributed on the surface of the gypsum board;

[0011] Therefore, the control system calculates the time corresponding to a single gypsum board completely passing through the QR code scanning camera as follows:

[0012] The time T for a single gypsum board to completely pass through the QR code scanning camera = the length of the single gypsum board / the running speed of the roller.

[0013] As a preferred solution of the present invention, the control system controls the two-dimensional code scanning camera to start working when the detection result of the photoelectric sensor indicates that the gypsum board is detected;

[0014] After the two-dimensional code scanning camera starts working, the two-dimensional code scanning camera suspends scanning work based on the interruption signal received from the control system, and after the two-dimensional code scanning camera suspends scanning work for the interruption time set by the interruption signal, the two-dimensional code scanning camera restarts itself;

[0015] Among them, the interrupt signal sending module adjusts the interrupt time of each interrupt signal based on the number of interrupt signals sent, and takes the number n of QR codes on a single gypsum board as an interrupt signal group, wherein the interrupt time of the nth interrupt signal in a single interrupt signal group = the length of a single gypsum board / {(n+1)*roller running speed}.

[0016] As a preferred solution of the present invention, the time points when the control system sends an interrupt signal to the QR code scanning camera are: T / n, T / n*2, ...T, wherein T is the time for a single gypsum board to completely pass through the QR code scanning camera, n is the number of QR codes, and n≥2.

[0017] As a preferred solution of the present invention, the control system sends a first interrupt signal to the two-dimensional code scanning camera at time point T / n, at which time the two-dimensional code scanning camera has completed scanning the first two-dimensional code;

[0018] At the time point T / n*2, the control system sends a second interrupt signal to the two-dimensional code scanning camera, at which time the two-dimensional code scanning camera has completed scanning the second two-dimensional code;

[0019] At time point T, the control system sends the nth interrupt signal to the two-dimensional code scanning camera. At this time, the two-dimensional code scanning camera has scanned the last two-dimensional code on the single gypsum board.

[0020] Furthermore, the present invention also provides a two-dimensional code recognition and classification method for a gypsum board production line, comprising the following steps:

[0021] Step 100: The control system receives the detection result of the photoelectric sensor in real time, and the control system controls the two-dimensional code scanning camera to start working based on the detection result;

[0022] Step 200, calculating the time it takes for a single gypsum board to completely pass through the two-dimensional code scanning camera, and the control system controls the two-dimensional code scanning camera to interrupt once after scanning a two-dimensional code, so as to divide the two-dimensional code information scanned by the two-dimensional code scanning camera into different data queues;

[0023] Step 300: The control system classifies and transports the gypsum boards based on the identification content of each data queue by the QR code scanning camera.

[0024] As a preferred solution of the present invention, there is a transmission gap between two adjacent gypsum boards transported to the position of the photoelectric sensor;

[0025] Wherein, the detection data of the photoelectric sensor indicates that when the transmission distance between two adjacent gypsum boards is detected, the interrupt state of the two-dimensional code scanning camera is maintained;

[0026] When the detection data of the photoelectric sensor indicates that the detection result changes from the transmission interval to the gypsum board, the control system adjusts the two-dimensional code scanning camera from the interrupt state to the start state.

[0027] As a preferred solution of the present invention, in step 200, the formula for calculating the time corresponding to a single gypsum board completely passing through the two-dimensional code scanning camera is:

[0028] The time T for a single gypsum board to completely pass through the QR code scanning camera = the length of the single gypsum board / the running speed of the roller.

[0029] As a preferred solution of the present invention, the time points at which the control system sends an interrupt signal to the two-dimensional code scanning camera are: T / n, T / n*2, ... T, wherein T is the time for a single gypsum board to completely pass through the two-dimensional code scanning camera, n is the number of two-dimensional codes, and n≥2;

[0030] Wherein, when the two-dimensional code scanning camera scans the 1st, 2nd, ..., (n-1)th two-dimensional code, the two-dimensional code scanning camera returns to the startup state each time after receiving an interrupt signal;

[0031] When the two-dimensional code scanning camera scans the nth two-dimensional code, the two-dimensional code scanning camera maintains an interrupt state each time after receiving an interrupt signal.

[0032] As a preferred solution of the present invention, in step 300, matching content is set in the control system, and the control system compares the data queue corresponding to the two-dimensional code scanned and recognized by the two-dimensional code scanning camera with the matching content;

[0033] When the data queue corresponding to the two-dimensional code scanned and identified by the two-dimensional code scanning camera is the same as the matching content, the conveying roller performs the same type of distribution of gypsum boards;

[0034] When the data queue corresponding to the two-dimensional code scanned and recognized by the two-dimensional code scanning camera is different from the matching content, the conveyor roller performs heterogeneous distribution of gypsum boards.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] After the cutter cuts the continuous gypsum boards, the gypsum boards enter the subsequent process section at a uniform speed. At this time, the QR code of each board is scanned at high speed by a QR code scanning camera and each QR code is distinguished. The classified transportation of the gypsum boards is realized based on the recognized QR code information. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] 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.

[0043] like Figure 1 As shown, the present invention provides a two-dimensional code recognition and classification system for a gypsum board production line, comprising: a two-dimensional code scanning camera 1, a photoelectric sensor 2 and a control system 3.

[0044] The two-dimensional code scanning camera 1 is used to identify the information of all two-dimensional codes on the cut single gypsum board.

[0045] The photoelectric sensor 2 is installed at the position of the two-dimensional code scanning camera 1 , and the photoelectric sensor 2 is used to detect the gypsum board transmitted to the position of the two-dimensional code scanning camera 1 .

[0046] The control system 3 is connected to the two-dimensional code scanning camera 1 and the photoelectric sensor 2. An interrupt signal sending module 4 is provided in the control system 3. The control system 3 controls the operation of the two-dimensional code scanning camera 1 based on the detection result of the photoelectric sensor 2. The control system 3 calculates the interruption time point of the two-dimensional code scanning camera 1, and uses the interrupt signal sending module 4 to send an interrupt signal to the two-dimensional code scanning camera 1 at the interruption time point, so that the control system 3 receives the two-dimensional code information scanned by the two-dimensional code scanning camera 1 in sequence and classifies the gypsum board based on the two-dimensional code information.

[0047] In the upstream of the entire gypsum board production line, a QR code is first printed on the surface of the produced gypsum board. The QR code information includes various information such as composition information, manufacturer information, and usage information. In order to ensure that all QR codes are included on a single gypsum board when the gypsum board is cut, the distance between two adjacent QR codes and the distance between the outermost QR code and the cutter assembly are set to be equal.

[0048] After the continuous gypsum boards are cut by the cutter, the gypsum boards will enter the subsequent process section at a uniform speed. At this time, the QR code scanning camera 1 is required to scan the QR code of each gypsum board at high speed and distinguish each QR code.

[0049] In order to distinguish the QR codes, this embodiment regulates the QR code scanning camera 1 from the scanning working state to the interrupted scanning working state by sending the interruption time point at a fixed time. At this time, the QR code scanning camera 1 sends the scanned information to the control system 3. The control system 3 receives the QR code information obtained by the QR code scanning camera 1 each time, so as to distinguish each QR code and identify the product information corresponding to each QR code.

[0050] That is to say, this embodiment is used to adjust the single exposure duration of the two-dimensional code scanning camera 1. The two-dimensional code scanning camera 1 scans a two-dimensional code within each exposure duration and sends the scanned two-dimensional code information to the upper control system.

[0051] In order to facilitate the regulation of the single exposure duration of the QR code scanning camera 1, the QR code printing stage in this embodiment adjusts the working mode of the printing system, so that the number of QR codes printed on the surface of a single gypsum board is at least two, and the QR codes are evenly distributed on the surface of the gypsum board.

[0052] Therefore, the formula for the control system 3 to calculate the time corresponding to a single gypsum board completely passing through the QR code scanning camera 1 is:

[0053] The time T for a single gypsum board to completely pass through the QR code scanning camera 1 = the length of the single gypsum board / the running speed of the roller.

[0054] When identifying the QR code information of a single gypsum board, the specific implementation method of starting the QR code scanning camera 1 is as follows:

[0055] When the detection result of the photoelectric sensor 2 indicates that the gypsum board is detected, the control system 3 controls the two-dimensional code scanning camera 1 to start working;

[0056] After the two-dimensional code scanning camera 1 starts working, the two-dimensional code scanning camera 1 suspends scanning based on the interrupt signal received from the control system 3, and after the two-dimensional code scanning camera 1 suspends scanning for the interrupt time set by the interrupt signal, the two-dimensional code scanning camera 1 restarts itself.

[0057] Among them, the interrupt signal sending module 4 adjusts the interrupt time of each interrupt signal based on the number of interrupt signals sent, and takes the number n of QR codes on a single gypsum board as an interrupt signal group, wherein the interrupt time of the nth interrupt signal in a single interrupt signal group = the length of a single gypsum board / {(n+1)*roller running speed}.

[0058] When the QR code scanning camera 1 receives the interrupt signal sent by the control system 3 to suspend scanning, and after a short pause, the QR code scanning camera 1 restarts automatically and scans the next QR code until the last QR code of a single gypsum board is scanned. At this time, the QR code scanning camera 1 receives the interrupt signal sent by the control system 3 to suspend scanning, and will no longer restart automatically.

[0059] The time points at which the control system 3 sends an interrupt signal to the two-dimensional code scanning camera 1 are: T / n, T / n*2, ...T, where T is the time for a single gypsum board to completely pass through the two-dimensional code scanning camera 1, n is the number of two-dimensional codes, and n≥2.

[0060] At time point T / n, the control system 3 sends a first interrupt signal to the two-dimensional code scanning camera 1. At this time, the two-dimensional code scanning camera 1 has already scanned the first two-dimensional code;

[0061] At the time point T / n*2, the control system 3 sends a second interrupt signal to the two-dimensional code scanning camera 1. At this time, the two-dimensional code scanning camera 1 has already scanned the second two-dimensional code;

[0062] By analogy, at time point T, the control system 3 sends the nth interrupt signal to the two-dimensional code scanning camera 1. At this time, the two-dimensional code scanning camera 1 has scanned the last two-dimensional code on the single gypsum board.

[0063] Among them, when the two-dimensional code scanning camera 1 has scanned the last two-dimensional code on a single gypsum board and received the nth interrupt signal, the two-dimensional code scanning camera 1 maintains the interrupted scanning state until the photoelectric sensor 2 scans the next single gypsum board into the position of the two-dimensional code scanning camera 1. At this time, the two-dimensional code scanning camera 1 that maintains the interrupted scanning state is restarted to scan the first two-dimensional code of the gypsum board. The above work is repeated to scan all the gypsum boards in sequence.

[0064] The two-dimensional code recognition classification method of the above two-dimensional code recognition classification system is as follows: Figure 2 As shown, the specific steps include:

[0065] Step 100: The control system receives the detection result of the photoelectric sensor in real time, and the control system controls the two-dimensional code scanning camera to start working based on the detection result;

[0066] Step 200, calculating the time it takes for a single gypsum board to completely pass through the two-dimensional code scanning camera, and the control system controls the two-dimensional code scanning camera to interrupt once after scanning a two-dimensional code, so as to divide the two-dimensional code information scanned by the two-dimensional code scanning camera into different data queues;

[0067] There is a transmission gap between two adjacent gypsum boards transported to the position of the photoelectric sensor;

[0068] The detection data of the photoelectric sensor indicates that when the transmission distance between two adjacent gypsum boards is detected, the QR code scanning camera is kept in an interrupt state;

[0069] When the detection data of the photoelectric sensor indicates that the detection result changes from the transmission interval to the gypsum board, the control system adjusts the QR code scanning camera from the interrupt state to the start state.

[0070] In step 200, the formula for calculating the time corresponding to a single gypsum board completely passing through the QR code scanning camera is:

[0071] The time T for a single gypsum board to completely pass through the QR code scanning camera = the length of the single gypsum board / the running speed of the roller.

[0072] The time points at which the control system sends an interrupt signal to the QR code scanning camera are: T / n, T / n*2, ... T, where T is the time for a single gypsum board to completely pass through the QR code scanning camera, n is the number of QR codes, and n≥2;

[0073] When the two-dimensional code scanning camera scans the first, second, ..., (n-1)th two-dimensional code, the two-dimensional code scanning camera returns to the start state each time after receiving an interrupt signal;

[0074] When the two-dimensional code scanning camera scans the nth two-dimensional code, the two-dimensional code scanning camera maintains an interrupt state each time after receiving an interrupt signal.

[0075] Step 300: The control system classifies and transports the gypsum boards based on the identification content of each data queue by the QR code scanning camera.

[0076] In step 300, matching content is set in the control system, and the control system compares the data queue corresponding to the QR code scanned and recognized by the QR code scanning camera with the matching content;

[0077] When the data queue corresponding to the QR code scanned and recognized by the QR code scanning camera is the same as the matching content, the conveyor roller distributes the gypsum boards of the same type;

[0078] When the data queue corresponding to the QR code scanned and recognized by the QR code scanning camera is different from the matching content, the conveyor roller performs heterogeneous distribution of gypsum boards.

[0079] That is, after the cutter cuts the continuous gypsum board, the gypsum board will enter the subsequent process section at a uniform speed. At this time, the QR code scanning camera needs to scan the QR code of each board at high speed and distinguish each QR code. In this embodiment, a QR code scanning camera is installed above the roller, and the time T for a single gypsum board to pass through the QR code scanning camera is calculated according to the length of the cut single gypsum board and the running speed of the roller. = Single gypsum board length / roller running speed.

[0080] The QR code scanning camera scans continuously, so an interrupt signal is required to the scanning device. When the scanning camera receives the interrupt signal, it means that the first QR code has been scanned and the next QR code can be scanned. Assuming that there are four QR codes evenly distributed on each gypsum board, the interrupt time of the first QR code is T / 4, the second interrupt time is T / 2, the third interrupt time is 3T / 4, and the fourth interrupt time is T.

[0081] Therefore, in this embodiment, the control system ends the interruption timer every T / n (where T is the time for a single gypsum board to pass through the QR code scanning camera completely, and n is the number of QR codes on a single gypsum board) and outputs an interruption signal. At this time, the QR code scanning camera stops scanning after receiving the interruption signal. When the interruption signal ends, the QR code scanning camera continues to scan the next QR code. In this way, the system distinguishes four QR codes and corresponds to the corresponding product information.

The protection scope of the present application is defined by the claims.
