Description

Technical Field

[0001] The present invention relates to the technical field of production data processing, and in particular to a method for transmitting production information across workstations. Background Art

[0002] On the automated production line, the production data of several stations are very critical and need to be collected or bound. The conventional approach is to use a barcode scanner to bind the production information data with the barcode attached to the product. However, due to structural limitations of the product itself or cost considerations, these stations are not equipped with barcode scanners or cannot scan, making it difficult to collect production information data or bind data. During the production process, it is often necessary to take the workpiece out of a certain workstation for inspection. After the inspection is completed, the workpiece needs to be placed back on the original workstation to continue the next production process. This requires the data collection method to be highly flexible.

[0003] However, in the actual production process, due to space limitations, some workstations cannot be equipped with identification devices for all production information. Summary of the invention

[0004] Technical purpose: In view of the defects in the prior art, the present invention discloses a method for transmitting production information across workstations, which identifies different production information at different workstations and finally performs data collection and data binding, thereby greatly simplifying the production process and improving production efficiency.

[0005] Technical solution: In order to achieve the above technical objectives, the present invention adopts the following technical solution.

[0006] A method for transmitting production information across workstations comprises the following steps: Step 1: several workstations are set up on the production line. The products on the production line pass through each workstation in turn. An identification device is set up at each workstation. A production information identification area is attached to the product. The identification device processes the production information identification area to obtain the production information of the product. Step 2: At each workstation, the production information is obtained through the identification device and stored in the corresponding data area, and a stacking operation is performed; wherein each data area includes a plurality of storage areas, and each stacking operation is performed to store one piece of production information in one storage area; Step 3: The last workstation obtains production information and compares it with the data in the first storage area of ​​the data area of ​​the first workstation. If the comparison is consistent, a pop operation is performed and a terminator is set at the end of the popped data to complete the cross-workstation data transfer of a product.

[0007] Preferably, the product is affixed with a nameplate code, a barcode, a transition code, and an RFID electronic tag, and the nameplate code, barcode, transition code, and RFID electronic tag each carry production information.

[0008] Preferably, the identification device is a device for identifying production information in a nameplate code, a barcode, a transition code, or an RFID electronic tag.

[0009] Preferably, the data area of ​​each workstation is initialized before the production information is transmitted, that is, the storage area is initialized to the number 0 or a special character.

[0010] Preferably, the method also includes inserting products on the production line. When inserting products, step two also includes: at the workstation where the product needs to be inserted, pausing the entry of other products, and jumping down the data in the data area of ​​all previous workstations once, storing the production information of the inserted product in the top-level data of the data area of ​​the workstation and all previous workstations; and continuing to start the production line.

[0011] Preferably, the method also includes taking out products from the production line. When taking out products, step two also includes: after the product to be taken out completes the stacking operation at the workstation, stop entering the next workstation and pause the production line; after the product to be taken out is taken out from the production line, delete the top layer data in the data area of ​​the workstation and all previous workstations, and jump up the remaining data once; continue to start the production line.

[0012] Beneficial effects: 1. The method of the present invention can break through the limitations of the structure or product itself, identify different production information at different workstations, and finally perform data collection and data binding, which can simplify the mechanical structure design, greatly simplify the production process, and improve production efficiency; 2. The present invention determines the accuracy of data by comparing whether two data are consistent, so that the order of data and the order of workpieces can be guaranteed to be consistent, thereby ensuring the accuracy of data; 3. The present invention can realize the function of taking out or putting in products at each workstation by adding or deleting data in the data area of ​​each workstation, thereby increasing the flexibility of the production process.

DETAILED DESCRIPTION

[0014] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0015] As attached Figure 1 As shown, a method for transmitting production information across workstations of the present invention comprises the following steps: Step 1. Set up several workstations on the production line. The products on the production line pass through each workstation in turn. An identification device is set at each workstation. A production information identification area is attached to the product. The identification device processes the production information identification area to obtain the production information of the product; the production information identification area can be a QR code, a barcode or an RFID electronic tag, wherein the barcode includes a nameplate code and a transition barcode; the QR code, barcode and RFID electronic tag each carry production information; the identification device is a device for identifying the production information in the QR code, barcode and RFID electronic tag, such as a barcode scanner, a barcode reader, a visual identification device, an RFID identification device, etc.; the communication method between all workstations is PLC communication, Ethernet communication or serial communication.

[0016] Step 2: Each workstation obtains production information through an identification device and stores it in a corresponding data area, and performs a stacking operation; wherein each data area includes a plurality of storage areas, and the data area of ​​each workstation is initialized before the production information is transmitted, that is, the storage areas are initialized to the number 0 or a special character, and the special character can be an underscore; each stacking operation is performed to store a piece of production information in a storage area, overwriting the original number 0 or special character, and when multiple products flow through the workstation, they are stored in the storage area according to the first-in-first-out stack rule, that is, all production information is stored in storage area 0, storage area 1, storage area 2... in sequence; Step 3: The last station obtains production information and compares it with the data in the first storage area of ​​the data area of ​​the first station. If the comparison is consistent, a pop operation is performed and a terminator is set at the end of the popped data to complete the cross-station data transfer of a product. After the data is taken out, the data in the storage area of ​​all data areas jumps up once. Among them, the identification device of the last station is the same as that of the first station, which is used to verify whether the data is correct. Therefore, at the last station, the information of the first station, such as barcode information, is identified and compared with the data in the first storage area of ​​the data area of ​​the first station. If the comparison is consistent, it means that there is no problem with the data and the pop operation can be performed. If the comparison is inconsistent, it means that there is a problem with the data. If a product is inserted in the middle, an alarm must be issued to shut down the machine.

[0017] A method for transmitting production information across workstations in this embodiment also includes inserting products on the production line. When inserting products, step two also includes: at the workstation where the product needs to be inserted, pausing the entry of other products, and jumping down the data in the data areas of all workstations before the workstation once, that is, the data in all storage areas in the data area are overwritten one bit downward in the address order of the storage areas, and the production information of the inserted product is stored in the top-level data of the data area of ​​the workstation and all previous workstations; and continuing to start the production line.

[0018] A method for transmitting production information across workstations in this embodiment also includes taking out products from the production line. When taking out products, step two also includes: after the product to be taken out completes the stacking operation at the workstation, stop entering the next workstation and pause the production line; after the product to be taken out is taken out from the production line, delete the top layer data in the data area of ​​the workstation and all previous workstations, and jump up the remaining data once, that is, the data in all storage areas in the data area are overwritten one bit upwards according to the address order of the storage areas; and continue to start the production line. Example

[0019] As attached Figure 2 As shown, in this embodiment, 4 workstations are set up and applied to the nameplate assembly production line of the meter post-processing line, that is, applied to the binding of the nameplate code, module code, and transition barcode. Due to mechanical structure limitations, the nameplate placement process, the electronic label affixing process, and the module placement process cannot be completed at the same workstation. A cross-workstation production information transmission method of this embodiment includes: When the product enters station 1, it first scans the barcode and stores the scanned barcode in storage area 0 of data area 1 to complete a stacking operation; then the product enters station 2, and after the product completes the production process at station 2, the corresponding production information data is stored in storage area 0 of data area 2 to complete a stacking operation. After entering station 3 and completing the production process at station 3, the corresponding production information data is also subjected to the same operation as station 2. Then the product will enter station 4. When the product completes the production process at station 4, the corresponding production information data is pushed into the stack. At the same time, after the barcode scanner completes the scanning, it is compared with the barcode in storage area 0 in data area 1. If the comparison is consistent, it means that there is no problem in the data transmission process, and thus a pop operation is performed. The above steps complete the cross-station data transmission of a product.

[0020] As attached Figure 3 As shown, it is a schematic diagram of the stacking operation. Figure 3 The figure shows the stacking flow chart when the digital 0 is used for initialization. The stacking operation is to store the production information data of each product at the corresponding workstation into the storage area in the data area in the order in which the products flow through the production line. This ensures that when the production information data of the product at the corresponding workstation needs to be taken out, the data in the same storage area of ​​the data area of ​​the corresponding workstation is the production information data of the product.

[0021] As attached Figure 4 As shown, it is a schematic diagram of the stacking process. Figure 4 The figure shows the stacking flow chart when the initialization method is digit 0. Since the stacking process is stored in the order in which the products flow into the production line, when the first product flows to the station where data needs to be taken out, the product is first scanned and the scanned barcode data is compared with the first barcode data of the first station (that is, the barcode data of the product stored in the first station), which is also the data stored in the storage area 0 of the data area 1. If the comparison is consistent, it means that the product is in the order of storing data and the order in which the product flows into the stacking station, indicating that the data is accurate. If it is inconsistent, it means that the order in which the product flows into the stacking station is inconsistent with the order in which the data is stored, and the data is incorrect. After the data comparison is correct, the data in the first storage area of ​​each station data area is the production information data of this product. After taking out the data in the first storage area, it is necessary to jump the data in sequence (the second data is stored in the first data, the third data is stored in the second data, the fourth data is stored in the third data, and so on, until the first data from the end is stored in the second data from the end) and then the last data is replaced with 0 or a special character; in this way, it can be ensured that the data in the first storage area is the production information data of the next product.

[0022] The method involved in the present invention has no limit on the number of intermediate workstations under the premise of ensuring storage space. The newly added workstations only need to save the data in the same stacking manner, and then take out the data at the popping workstation in the same manner and delete the taken out data. The method involved in the present invention can process data from many workstations at one time.

[0023] When a product needs to be inserted into the middle station (for example, a product needs to be inserted into station 3), in order to ensure data integrity, first stop the product from entering station 3, and when station 3 is vacant, jump down all the data of stations 1 and 2, and then put the data of the product to be inserted in stations 1 and 2 into the first data area of ​​the corresponding stations 1 and 2, and then put the product into the empty station 3, start the production line, and the insertion of a product is completed. The product can be inserted into station 2 in the same way.

[0024] When a product needs to be taken out from the middle station (for example, a product needs to be taken out from station 3), wait until the product completes the action at station 3, stop entering station 4, then pause the production line, take the product out from station 3, then delete the first data in the corresponding data areas of stations 1, 2 and 3, then jump all the data in the data areas of stations 1, 2 and 3, and restart the production line, thus completing the operation of taking out a product from station 3. It can be known from the description of the above implementation mode that those skilled in the art can clearly understand that all or part of the steps in the above-mentioned embodiment method can be implemented by means of software plus a general hardware platform. Based on such an understanding, the technical solution of the present application can be embodied in the form of a software product, and the computer software product can be stored in a storage medium, and the memory can be various types of memory, which can be a random access memory, a read-only memory, a flash memory, etc., such as a read-only memory (English: read-only memory, ROM) / RAM, a disk, an optical disk, etc., including a number of instructions for a computer device (which can be a personal computer, a server, or a network communication device such as a router) to execute the methods described in each embodiment of the present application or some parts of the embodiments.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
