Description

Technical Field

[0001] This invention relates to the field of automated production, and more specifically to a method for rapidly implementing restricted operation of the Chamber during product manufacturing. Background Technology

[0002] Existing main manufacturing equipment such as CVD and DRY have a situation where one product corresponds to multiple chambers for production. If the product produced in a certain chamber fails to meet the quality requirements, a large number of abnormal products may accumulate in a short period of time, affecting production capacity and costs. Summary of the Invention

[0003] To address the technical problems existing in the prior art, this invention provides a method for rapidly implementing chamber restricted operation during product manufacturing. Through upstream and downstream command control, the equipment can quickly receive information to prevent existing products from being sent to the restricted chamber, thereby reducing cost losses and improving production and warehousing efficiency.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] A method for rapidly achieving chamber-controlled operation during product manufacturing includes the following steps:

[0006] Step 1: The Manufacturing Execution System (MES) provides an interface to add a PLC working data address area to the MES to match the automated production control system;

[0007] Step two: The manufacturing execution system provides a message interface to generate chamber restriction signals and sends these signals to the CVD and DRY equipment via working data. After receiving the chamber restriction signals, the equipment automatically implements chamber restriction operation based on the signals.

[0008] As a preferred technical solution, in step two, after receiving the chamber restriction signal, the equipment automatically generates information about the chambers that need to be restricted. When the manufacturing execution system sends and distributes the work data, the equipment begins to automatically execute the instructions for chamber restriction operation.

[0009] As a preferred technical solution, after receiving the instruction to restrict or prohibit operation from the automated production control system, the equipment first records it in the database, determines whether to enable the restricted or prohibited operation based on the current process status, and then informs which chamber to restrict or prohibit through the automated production control system's message interface.

[0010] As a preferred technical solution, the equipment writes the restriction information to the working data address area, reports the card holder status change event to the automated production control system, and after the automated production control system responds, the equipment downloads the card holder data, reads the restriction chamber information, and automatically executes the restriction function.

[0011] As a preferred technical solution, once the production of restricted or prohibited products is completed, the automated production control system issues a shutdown command, and the restricted or prohibited operation function of the equipment is turned off.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The present invention discloses a method for rapidly implementing chamber restricted operation during product manufacturing. Through upstream and downstream command control, the equipment can quickly receive information to prevent existing products from being sent to the restricted chamber, thereby reducing cost losses and improving production and warehousing efficiency. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the data transmission communication interface in the method for rapidly achieving chamber restricted operation during product manufacturing according to the present invention;

[0015] Figure 2 This is a flowchart of a method for rapidly achieving chamber restricted operation during product manufacturing according to the present invention. Detailed Implementation

[0016] The technical solution of the present invention will be further described below with reference to specific embodiments:

[0017] like Figure 1 As shown, a method for rapidly achieving chamber-controlled operation during product manufacturing includes the following steps:

[0018] Step 1: The Manufacturing Execution System (MES) provides an interface to add a PLC working data address area to the MES to match the automated production control system;

[0019] Step 2: The manufacturing execution system provides a message interface to generate chamber restriction signals and sends these signals to the CVD and DRY equipment via working data. After receiving the chamber restriction signals, the equipment automatically generates information about the chambers that need to be restricted. Once the manufacturing execution system sends out the working data, the equipment automatically begins to implement chamber restriction operation.

[0020] like Figure 2 As shown, BC represents the equipment, MES system is the automated production control system, Redis is a log-based database, and Chamber represents a storage compartment. After receiving a restricted operation instruction from the automated production control system, the equipment first records it in the Redis database. Based on the current process status, it determines whether to enable the restricted operation, and then the automated production control system's message interface informs which chamber to restrict.

[0021] The equipment writes the restriction information to the job data (jobDate) address area, reports the card holder status change event to the automated production control system, and after the automated production control system responds, the equipment downloads the card holder data, reads the restriction chamber information, and automatically executes the restriction function.

[0022] Once the production of restricted or prohibited products is completed, the automated production control system issues a shutdown command, and the equipment immediately shuts down the restricted or prohibited operation functions.

[0023] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. Those skilled in the art can make non-inventive modifications to this embodiment as needed after reading this specification, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
