[0022] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are 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 are within the scope of protection of this application.

[0023] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0024] The following describes in detail the monitoring method for error prevention and traceability of SMT production lines provided by the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0025] like Figure 1 As shown, a flow chart of a monitoring method for error prevention and traceability of an SMT production line provided by an embodiment of the present application is shown, as shown in Figure 1, including the following steps:

[0026] S101, obtaining a first identification of an incoming material and a second identification of a PCB board.

[0027] Incoming materials are components that are ready to be placed on PCBs before being fed into the production line. Each tray is uniquely identified by a tag, such as an RFID tag or image label. The trays are pre-loaded with the designated components.

[0028] A unique number is also etched on each PCB board to indicate the identity information of each PCB board.

[0029] Therefore, during production, the specific materials fed into the production line can be tracked through the first identification of the incoming material and the second identification of the PCB board.

[0030] In some embodiments, the first identification of the incoming material and the second identification of the PCB board are obtained by identifying the radio frequency tag or image tag on the material tray and the number on the PCB board.

[0031] S102, query the matching relationship between the first identifier and the second identifier in the electronic production work order; if the first identifier and the second identifier match, execute S103 and S105; if the first identifier and the second identifier do not match, execute S104.

[0032] The corresponding materials for each PCB are pre-configured in the electronic production work order. Specifically, the corresponding relationship between the serial number of each PCB to be patched and the unique identifier of the tray containing its corresponding components is pre-configured and recorded in the electronically generated work order. Then, based on the first and second identifiers, the electronically generated work order is used to check whether the incoming material and the PCB currently being fed into the production line match. If a match is found, the incoming material is put into production on the SMT line. If not, a prompt is given to replace the incoming material.

[0033] Before formal production, first determine whether the components to be mounted on the PCB are the corresponding components. If they are, then mount them. If they are not, prompt to replace the materials, so as to avoid mounting the wrong components on the PCB, generating a lot of scrap and causing material waste.

[0034] In some embodiments, step S102 includes the following steps:

[0035] In response to receiving the confirmation information, the matching relationship between the first identifier and the second identifier is queried in the electronic production work order; the confirmation information is information confirming that the components in the incoming material are consistent with the components corresponding to the first identifier recorded in the electronic production work order.

[0036] Because the materials are loaded in the material tray, it is inevitable that material loading errors will occur, that is, the materials actually loaded in the material tray are not the materials that should be loaded. Therefore, it can be set here that the personnel go to the production line to confirm that the materials loaded in the material tray are the components corresponding to the first identifier configured in the early stage, that is, the components in the incoming materials described by the personnel are consistent with the components corresponding to the first identifier recorded in the electronic production work order. After the personnel confirms, the confirmation information is input through the user terminal or the input device of the monitoring system to confirm that the physical materials actually loaded in the material tray are the materials that should be loaded, and then the matching relationship between the first identifier and the second identifier is queried in the electronic production work order. This can avoid, to a certain extent, the mounting errors caused by the fact that the materials actually loaded in the material tray are not the materials that should be loaded.

[0037] S103, sending the incoming materials and the PCB board to the SMT production line and starting production.

[0038] In some embodiments, before production begins, one or several PCBs can be trial-mounted and performance tested. If these trial-produced PCBs pass the test, mass production can officially begin. If the test fails, the manufacturer can investigate whether the cause is a material placement error. This further reduces the possibility of placement errors.

[0039] S104, outputting an alarm message, wherein the alarm message is used to prompt the incoming material to be replaced with a material that matches the PCB board.

[0040] S105: After the production is completed, the first identifier and the second identifier are combined to generate a third identifier of the produced PCB board.

[0041] The third identification of the produced PCB board is a combination of the second identification of the PCB board before production and the first identification of the incoming components mounted on the PCB board. This can facilitate the traceability of the PCB board and materials used in the produced PCB board.

[0042] In an embodiment of the present application, before production begins, the electronic production work order is checked to see if the first identification of incoming materials to be sent to the production line matches the second identification of the PCB. If a match is found, the materials are then sent to the SMT production line for production. If a mismatch occurs, a prompt is given to replace the incoming materials, thereby avoiding incorrect components being placed on the PCB. Furthermore, the materials used in each production process can be monitored and tracked using the first identification of the incoming materials, the second identification of the PCB, and the third identification of the PCB after production.

[0043] In some optional implementations, before S101, the method further includes:

[0044] Obtaining a first model specification of the incoming material and a second model specification of the PCB board;

[0045] Querying the matching relationship between the first model specification and the second model specification in the electronic process sheet;

[0046] If the first model specification and the second model specification do not match, output a prompt message, wherein the prompt message is used to prompt the incoming material to be replaced with a material that matches the PCB board;

[0047] If the first model specification matches the second model specification, the first identification of the incoming material and the second identification of the PCB board are obtained.

[0048] SMT production is typically batch-produced, so the number of PCB boards and materials is necessarily very large. Each PCB board and material tray has a corresponding identifier, resulting in a very large amount of data. Matching and comparing the first and second identifiers takes a long time. However, the model specifications of PCB boards and materials within the same batch are usually fixed, so the amount of data is significantly smaller. Therefore, it is possible to directly query whether the first model specification of the incoming material matches the second model specification of the PCB board. If the model specifications do match, identity matching can be performed. If neither model specification matches, a prompt is issued to replace the material, eliminating the need for identity matching, thus conserving computing resources and improving production efficiency.

[0049] In some optional embodiments, the method further comprises:

[0050] Generate a fourth identifier for returned materials, and establish mapping relationships between the fourth identifier and the first identifier, between the fourth identifier and the second identifier, and between the fourth identifier and the third identifier.

[0051] When the incoming materials are used up, returned materials will be generated. The identity identifier of the returned materials (i.e., the fourth identifier) and the mapping relationship between the fourth identifier and the first identifier, the second identifier, and the third identifier will be generated, so that the materials in production can be tracked based on these corresponding relationships when needed later (such as product qualification rate quality analysis).

[0052] The monitoring method for error proofing and traceability of an SMT production line provided in an embodiment of the present application can be executed by a monitoring system for error proofing and traceability of an SMT production line. In the embodiment of the present application, the monitoring method for error proofing and traceability of an SMT production line performed by a monitoring system for error proofing and traceability of an SMT production line is used as an example to illustrate the system for error proofing and traceability monitoring of an SMT production line provided in an embodiment of the present application.
