Description

Technical Field

[0001] The present invention relates to the technical field of material management, and particularly relates to a multi-terminal material management system and method. Background Art

[0002] The semiconductor production process mainly includes the following steps: wafer processing, oxidation, lithography, etching, thin film deposition, interconnection, testing, and packaging. The semiconductor production workshop is a closed environment. Operators are responsible for managing several production equipment and obtaining production materials from the line side warehouse. The line side warehouse is managed, verified, and registered by material handlers, and replenishment and requisition of materials are carried out between the line side warehouse and the main and auxiliary material warehouses.

[0003] Currently in the semiconductor production workshop, the interactive management between material handlers and operators lacks clear requisition and registration process management. The requisition of materials is relatively chaotic and cannot be traced back. There are problems in reconciling the requisition transfer data of materials among the main and auxiliary material warehouses, the line side warehouse, and the production workshop. Summary of the Invention

[0004] To solve the above problems, the present invention provides a multi-terminal material management system and method. Through the equipment terminal, the line side warehouse terminal, and the material terminal, the processes of inventory checking, requisition, and registration of materials are standardized. At the same time, while realizing two-way interaction among all terminals in the whole process, independent one-way transmission of data and instruction signals is achieved to complete each link process. It can perform process tracing while ensuring data security.

[0005] The present invention provides a multi-terminal material management system, and the specific technical solution is as follows:

[0006] It includes a line side warehouse terminal, an equipment terminal, a material terminal, a management terminal, and a material management terminal;

[0007] The material terminal, the equipment terminal, and the line side warehouse terminal are all operation terminals;

[0008] The line side warehouse terminal includes a production plan unit and a material inventory record unit; the production plan unit receives the production plan form locally, and the material inventory record unit records the requisitioned and remaining materials, registers them in the material inventory record form, and stores them locally;

[0009] The equipment terminal includes a work order module, and the work order module records the materials required for the current production of the equipment;

[0010] The material terminal includes a material registration unit, which records the registration information when the material requisition is confirmed;

[0011] The material terminal is respectively connected to the equipment terminal and the line side warehouse terminal in an interactive manner, and the line side warehouse terminal is respectively connected to the management terminal and the material management terminal in an interactive manner.

[0012] Furthermore, the management terminal has a login permission, and the in-line storage terminal receives the production plan sent by the management terminal.

[0013] Furthermore, the in-line storage terminal further includes a login unit and a production plan setting unit. The login unit logs in to the administrator account, and the production plan setting unit has an operation permission. After logging in to the administrator account, the production plan is formulated through the production plan setting unit and stored locally.

[0014] Furthermore, the in-line storage terminal obtains the information of the materials to be received currently according to the production plan data and the data of the material inventory record unit, and sends the information of the materials to be received currently and the information of the material handler to the material management terminal.

[0015] Furthermore, the equipment terminal registers the information of the materials required according to the materials required by the current production equipment and generates a work order; the equipment terminal transmits the recorded data of the work order to the material terminal.

[0016] Furthermore, the material terminal records the information of the materials issued according to the work order and records the information of the issuer and the recipient confirmed.

[0017] Furthermore, the material terminal is provided with a signature unit, and the signature unit calls the signature interface after the material terminal receives a signature request.

[0018] Furthermore, a two-dimensional code identifier is provided on the work order, and the material terminal is provided with a code scanning module to obtain the corresponding work order data information by scanning the two-dimensional code identifier on the work order.

[0019] Based on the above management system, the present invention also provides a multi-terminal material management method, which is specifically as follows:

[0020] S1: The in-line storage terminal obtains the production plan, generates a production plan form and stores it locally, and outputs the information of the materials to be retrieved and the current material handler information according to the production plan content and the inventory data of the current in-line warehouse. At the same time, the information of the materials to be retrieved and the current material handler information are sent to the material management terminal of the main and auxiliary material warehouses and the material terminal;

[0021] S2: The current material handler obtains the information of the materials to be retrieved through the material terminal, verifies the identity at the material management terminal of the main and auxiliary material warehouses, and retrieves the corresponding materials;

[0022] S3: After the current material handler retrieves the materials, the material management terminal of the main and auxiliary material warehouses sends a retrieved signal to the in-line storage terminal. After receiving the retrieved signal, the in-line storage terminal is set to the state of waiting for material inventory record;

[0023] S4: The current material handler stores the materials in the warehouse and sends an inbound signal to the in-line warehouse terminal through the material terminal. After receiving the inbound signal, the in-line warehouse terminal updates the material registration through the material inventory record unit;

[0024] S5: The equipment terminal generates a work order and sends it to the material terminal, and the corresponding operator picks up the materials from the in-line warehouse;

[0025] S6: According to the data information in the work order, the material terminal retrieves the material registration record form through the material registration unit, and the operator verifies the material registration content on the material registration record form;

[0026] S7: After the operator verifies, the material terminal sends a verification completion signal to the equipment terminal. After receiving the signal, the equipment terminal sends a signature request to the material terminal;

[0027] S8: After receiving the signature request, the material terminal brings up the signature interface, and the operator signs. After signing, the material terminal feeds back the material pickup information to the in-line warehouse terminal, and the in-line warehouse terminal updates the remaining material information in the material inventory record unit.

[0028] The beneficial effects of the present invention are as follows:

[0029] The present invention designs a one-way material pickup registration for the in-line warehouse terminal - material terminal - material management terminal and the equipment terminal - material terminal, designs a multi-terminal interactive management for material pickup replenishment based on the material terminal and the in-line warehouse terminal and material pickup for production equipment, and completes the registration record of the material pickup process. Among them, based on the in-line warehouse terminal, material terminal and material management terminal, data is synchronously and unidirectionally transmitted in the material inventory pickup link, and execution signals are unidirectionally fed back among multiple terminals. Based on the equipment terminal, material terminal and in-line warehouse terminal, data is unidirectionally transmitted among multiple terminals in the production material requisition link, and execution signals are unidirectionally interactively transmitted, avoiding the autonomous operations of the material handler and the operator during the entire process execution, ensuring the unilateral independence of the data in the in-line warehouse terminal, and the system as a whole realizes the standardization of material pickup in multiple links and multiple terminals, ensuring data security.

[0058] Embodiment 2

[0059] Embodiment 2 of the present invention discloses a multi-end material management method, based on the multi-end material management system described in Embodiment 1, as Figure 2 shown, the specific process is as follows:

[0060] S1: The in-line storage end obtains the production plan, generates a production plan form and stores it locally, and outputs the material information to be retrieved and the current material handler information according to the production plan content and the inventory data of the current in-line warehouse. At the same time, the material information to be retrieved and the current material handler information are sent to the material management end of the main and auxiliary material warehouses and the material end.

[0061] Specifically, the production plan can be received from the management end. The management personnel can set the production plan through the management end and send it to the in-line storage end.

[0062] The management personnel can also directly generate a production plan form through operations on the in-line storage end and store it locally.

[0063] S2: The current material handler obtains the material information to be retrieved through the material end, verifies the identity at the material management end of the main and auxiliary material warehouses, and retrieves the corresponding materials.

[0064] Specifically, the material handler verifies the identity at the material management end by using radio frequency interaction technology. Through the RFID receiving module configured on the material management end, the identity verification is completed by swiping the employee magnetic card.

[0065] S3: After the current material handler retrieves the materials, the material management end of the main and auxiliary material warehouses sends a received signal to the in-line storage end. After receiving the received signal, the in-line storage end is set to the state of waiting for material inventory records.

[0066] Specifically, after the material management terminal sends a received signal to the in-line storage terminal, the corresponding material receipt record is set to the received status identifier and stored locally. By node-processing each link of the receipt, it is convenient for process traceability.

[0067] S4: The current material handler stores the materials in the warehouse and sends a warehousing signal to the in-line storage terminal through the material terminal. After receiving the warehousing signal, the in-line storage terminal updates the material registration through the material inventory record unit;

[0068] The material handler picks up materials from the main and auxiliary material warehouses and stores them in the in-line warehouse. The entire process avoids data operations on the in-line storage terminal. In the entire material management system, the update of the material data at the in-line storage terminal starts from the production plan and the remaining material data, and is autonomously updated based on the signal interaction of each terminal, ensuring data security and facilitating material verification.

[0069] S5: The equipment terminal generates a work order and sends it to the material terminal, and the corresponding operator picks up materials from the in-line warehouse;

[0070] Specifically, when the production materials of the production equipment reach the end of their lifespan or an abnormality triggers an alarm, the operator operates the equipment terminal to obtain a work order according to the alarm information prompt;

[0071] After the work order is generated, if the equipment terminal is equipped with a peripheral printer, the work order can be printed out and taken to the material terminal, or the work order can be directly sent to the material terminal through the equipment terminal.

[0072] S6: According to the data information of the work order, the material terminal calls out the material registration record form through the material registration unit, and the operator verifies the material registration content on the material registration record form;

[0073] Specifically, the material terminal scans the QR code identifier on the work order to obtain the work order data, calls out the material registration record form, and then the operator verifies whether the material registration content on the material registration record form is consistent with the work order data according to the work order information.

[0074] S7: After the operator completes the verification, the material terminal sends a verification completion signal to the equipment terminal. After receiving the signal, the equipment terminal sends a signature request to the material terminal;

[0075] S8: After receiving the signature request, the material terminal calls out the signature interface, and the operator signs. After completing the signature, the material terminal feeds back the material receipt information to the in-line storage terminal, and the in-line storage terminal updates the remaining material information in the material inventory record unit.

[0076] Specifically, after the operator finishes signing, it will jump to a new signature interface for the current stock clerk to handle the signature. In practice, the current stock clerk may not be the same person as the stock clerk during the physical inventory; after the current stock clerk finishes signing, the corresponding receipt record on the material registration record form is attached with the electronic signatures of the operator and the stock clerk and stored locally with query permissions set.

[0077] The query permission is set so that only administrators can query. When a stock clerk queries, a query request needs to be sent to the management terminal, and only after receiving the feedback allowing the query can the stock clerk perform data query through the material terminal.

[0078] The present invention is not limited to the foregoing specific embodiments. The present invention extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
