[0002] With the rapid development and application of the manufacturing industry, customers have higher and higher requirements for PCB production processes.

Repeated checking takes too long, which reduces the energy efficiency of the SMT production line. Moreover, one wrong material may cause batches of products to be scrapped. Therefore, a software is needed to control the loading and unloading of materials.

[0048] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] Reference Figure 1 , Figure 1 This is a structural block diagram of the first embodiment of the placement machine loading error prevention system of the present invention.

[0050] This embodiment provides a data acquisition module 10, a background service module 20, and a loading module 30 in the placement machine loading error prevention system, wherein the background service module 20 is connected to the data acquisition module 10 and the loading module 30 respectively;

[0051] The data acquisition module 10 is used to collect the operation data of the placement machine and send the operation data of the placement machine to the background service module 20. The operation data of the placement machine at least includes the material station table information of the placement machine, the material usage information of each slot, and the material throwing information;

[0052] The backend service module 20 is configured to receive the placement machine operation data sent by the data acquisition module 10, generate and establish material station table information according to the placement machine operation data, and build a database according to the placement machine operation data and the material station table information;

[0053] The loading module 30 is used to obtain material and placement machine data, and obtain the corresponding relationship between the material and the placement machine based on the material and placement machine data;

[0054] The loading module 30 is also used to obtain the material station table information in the database of the background service module 20. When there is no corresponding relationship between the material and the placement machine in the material station table information, the machine is locked to prevent the placement machine from loading errors.

[0055] It's important to note that the backend service module is a server running on the company's server. It interacts with other modules via HTTP, primarily providing data interfaces for other modules and receiving data for storage in a database. With the rapid development and application of the manufacturing industry, customers are increasingly demanding PCB production processes. The placement machine is the absolute core of any SMT production line. However, the placement machine's preparation process is lengthy. Because material particles are indistinguishable to the human eye, manual loading is prone to errors. Repeated verification is time-consuming, sacrificing SMT production line energy efficiency. Furthermore, a single misplaced material can result in the scrapping of entire batches of products. Therefore, software is necessary to manage loading and unloading. Furthermore, we are concerned that if materials are depleted during high-speed operation of the SMT production line, the SMT line will halt production. In such cases, software is needed to monitor material usage and provide early warnings.

[0056] It should be clear that the overall architecture of the present invention is as follows Figure 2As shown, it mainly includes: data acquisition module, background service module, loading module, data warning module and data tracing module. The data acquisition module collects placement machine data and uploads it to the background. The loading module obtains real-time remaining material data for warning, and transmits the loading information to the background service after scanning the code through the PDA. The data tracing module queries data through the background service.

[0057] In this embodiment, a data acquisition module, a background service module and a loading module are set in the placement machine loading error prevention system, wherein the background service module is connected to the data acquisition module and the loading module respectively; the data acquisition module is used to collect placement machine operation data and send the placement machine operation data to the background service module, and the placement machine operation data includes at least one of the placement machine material station table information, each slot material usage information and throwing material information; the background service module is used to receive the placement machine operation data sent by the data acquisition module, generate a material station according to the placement machine operation data The loading module is used to obtain the material and placement machine data, and obtain the corresponding relationship between the material and the placement machine based on the material and placement machine data; the loading module is also used to obtain the material station table information in the background service module database, and when the corresponding relationship between the material and the placement machine does not exist in the material station table information, the machine is locked to prevent the placement machine from loading errors, thereby preventing batches of PCB placement failures in production due to loading errors without affecting the efficiency of the placement machine.

[0058] Reference Figure 3 , Figure 3 This is a structural block diagram of the second embodiment of the placement machine loading error prevention system of the present invention. Based on the above-mentioned first embodiment, the second embodiment of the placement machine loading error prevention system of the present invention is proposed.

[0059] This embodiment further includes the chip placement machine loading error prevention system through the data warning module 40, the data warning module 40 and the background service module 20 are respectively connected to the loading module 30;

[0060] The data warning module 40 is used to record the number and type of materials loaded by the loading module 30 when there is a correspondence between the materials and the placement machines in the material station table information, and obtain the number and type of materials used by the placement machines through the background service module database;

[0061] The data warning module 40 is also used to determine the remaining material based on the number and type of material loaded by the loading module 30 and the number and type of material used by the placement machine. When the number of remaining material particles is lower than the material particle number warning threshold, an audible and visual alarm is issued, and when the number of remaining material particles is lower than the stop operation threshold, the placement machine is controlled to stop running, and the stop operation threshold is less than the material particle number warning threshold.

[0062] In practice, the data warning module and the loading error prevention module share the same PDA. The module records the number and type of materials loaded from the loading module, and uses the data acquisition module to obtain the number and type of materials used by the placement machine. By subtracting materials of the same type, the remaining material in the machine is determined. The module then issues an alert based on the material count warning value set in the backend service module. If the number falls below a certain threshold, an audible and visual alarm is triggered, or the machine stops production if the number falls below a minimum threshold.

[0063] The chip placement machine loading error prevention system further includes: a data tracing module 50, which is connected to the background service module 20;

[0064] The data tracing module 50 is used to connect to the backend service module 20 via the website corresponding to the backend service to view the machine data integrated in the data collection module 10. The machine data integrated in the data collection module 10 includes at least the machine discard rate and machine efficiency;

[0065] The data tracing module 50 is further configured to query at least the operation data in the loading module 30 through the background service module 20, wherein the operation data includes at least one of: a failed operation, an operator of a successful operation, a time, and a material type;

[0066] The data tracing module 50 is further configured to generate and display corresponding data reports based on the machine data integrated in the data acquisition module 10 and the operation data in the loading module 30 .

[0067] It should be noted that the Data Traceability Module functions as a data search and display module. Log in through the backend service's corresponding URL. You can view machine data integrated within the Data Collection Module, such as machine rejection rate and efficiency. You can also query failed operations in the Loading Module, including the operator, time, and material type of successful operations.

[0068] The data acquisition module is further configured to access the chip placement machine database to obtain at least one of the chip placement machine material station table information, each slot material usage information, and discarded material information;

[0069] The data acquisition module is further used to create a MySQL database and store the acquired information in the MySQL database.

[0070] It should be noted that this module collects SMT machine operation data. The SMT machine serves as the core workstation, and we access the SMT machine database through real-time database access. The main information obtained includes the SMT machine material station table (i.e., the correspondence between the material type of the current SMT machine station and the SMT machine slot information), material usage information for each slot, and material discard information. This collected information is stored in a custom MySQL database for quick use by other modules.

[0071] The loading module 30 is used to scan the barcode on the material and the station code on the placement machine through the PDA scanning function and compare them. If the correspondence between the barcode on the scanned material and the station code on the machine exists in the material station table, it is determined that the loading is successful. Then, the number of barcode materials is queried through the material barcode and uploaded to the background service module.

[0072] The loading module 30 is also used to lock the placement machine if the correspondence between the barcode on the scanned material and the station code on the placement machine does not exist in the material station table, and unlock the placement machine when it is correct again after the PDA manually operates the material and updates the material.

[0073] It should be noted that this module is a handheld PDA that runs on a mobile app. It communicates with the service module via HTTP and obtains the material station table information uploaded to the backend service by the data acquisition module. Using the PDA's barcode scanning function, the barcode on the material and the station code on the machine are scanned and compared. If the corresponding relationship between the two codes exists in the material station table, the loading is judged to be successful. If not, it is a failure. If this fails, the machine will be locked and production will not be allowed. Manual material operation must be performed on the PDA and the material comparison must be updated to ensure that there are no problems before the machine can be unlocked (serving as an error prevention function). If successful, the number of barcoded materials will be queried through the material barcode and uploaded to the backend service.

[0074] In this embodiment, the remote module in the chip placement machine loading error prevention system includes: the data warning module, which is used to record the number and type of materials loaded by the loading module when there is a corresponding relationship between the material and the placement machine in the material station table information, and obtain the number and type of materials used by the placement machine through the background service module database; the data warning module is also used to determine the remaining materials based on the number and type of materials loaded by the loading module and the number and type of materials used by the placement machine, and to perform an audible and visual alarm when the number of remaining materials is lower than the material number warning threshold, and to control the placement machine to stop running when the number of remaining materials is lower than the stop operation threshold, and the stop operation threshold is less than the material number warning threshold. The chip placement machine loading error prevention system also includes: a data tracing module, which is connected to the backend service module; the data tracing module is used to connect to the backend service module through the website corresponding to the backend service and view the machine data integrated in the data acquisition module, the machine data integrated in the data acquisition module at least including the machine rejection rate and machine efficiency; the data tracing module is also used to query at least the operation data in the loading module through the backend service module, the operation data at least including at least one of: failed operations, operators of successful operations, time, and material type; the data tracing module is also used to generate and display corresponding data reports based on the machine data integrated in the data acquisition module and the operation data in the loading module. The data acquisition module is also used to access the chip placement machine database to obtain at least one of the chip placement machine material station table information, material usage information for each slot, and rejection information; the data acquisition module is also used to create a MySQL database and store the obtained information in the MySQL database. The loading module is used to scan the barcode on the material and the station code on the placement machine through the PDA scanning function and compare them. If the corresponding relationship between the barcode on the scanned material and the station code on the machine exists in the material station table, it is judged that the loading is successful, and the number of barcode materials is queried through the material barcode and uploaded to the background service module; the loading module is also used to lock the placement machine if the corresponding relationship between the barcode on the scanned material and the station code on the placement machine does not exist in the material station table, and unlock the placement machine when it is correct after manual material operation and material update by PDA, thereby preventing batch PCB placement failures in production due to loading errors without affecting the efficiency of the placement machine, effectively reducing production line risks, and making all data traceable, and being able to effectively review the data level to increase production efficiency.
