Description

Technical Field

[0001] This invention belongs to the field of PCBA address allocation technology, specifically relating to a control system and method for the PCBA SAS address allocation production process. Background Technology

[0002] In the current PCBA production process, there are quite a few boards that require SAS address allocation, mainly concentrated on HBA cards, RAID cards and other boards. SAS address allocation and binding management is an indispensable part of the PCBA production process, including a series of management processes such as SAS address allocation, binding, burning, and verification.

[0003] In existing technology control methods, the method of allocation on demand is generally used. That is, before the board is produced on the production line and before it reaches the testing and programming station, the operator manually scans the board's S / N and allocates and prints the corresponding SAS address label on site.

[0004] The control methods used in the existing technology have the following two drawbacks:

[0005] First: On the assembly line, labels are distributed and printed on the spot. Manually scanning, printing, and pasting labels wastes time and can easily become a bottleneck station.

[0006] Second: Lack of error prevention - missing or incorrectly pasted circuit boards cannot be detected immediately, posing a risk of them going to the next stage of production, ultimately leading to rework or even defective circuit boards being shipped to customers, resulting in huge losses.

[0007] This is a shortcoming of existing technology.

[0008] In view of this, it is very necessary to provide a control system and method for the PCBA SAS address allocation production process to solve the above-mentioned technical defects in the prior art. Summary of the Invention

[0009] The purpose of this invention is to address the deficiencies of the existing technology by providing a control system and method for the PCBA SAS address allocation production process, thereby solving the aforementioned technical problems.

[0010] The Chinese translations of the English abbreviations used in this application are as follows:

[0011] PCBA is an abbreviation for printed circuit board assembly, which refers to the assembly of printed circuit boards.

[0012] HBA is an abbreviation for Host bus adapter, referring to the host bus adapter.

[0013] RAID is an abbreviation for Redundant Arrays of Independent Disks, referring to a disk array.

[0014] SAS is an abbreviation for Serial Attached SCSI, referring to Serial Attached SCSI.

[0015] S / N is an abbreviation for Serial Number, which refers to a serial number.

[0016] PCB is an abbreviation for Printed Circuit Board, referring to printed circuit boards.

[0017] Pcs is an abbreviation for PIECES, meaning: one;

[0018] UPH is an abbreviation for Units Per Hour, which refers to production capacity.

[0019] To achieve the above objectives, the present invention provides the following technical solution:

[0020] A control system for the PCBA SAS address allocation production process includes:

[0021] The SAS address pool maintenance module is used to maintain the SAS address pool before PCBA work orders are issued, and to maintain the number and rules of SAS addresses that need to be allocated to each PCBA board.

[0022] The SAS address range allocation module is used to extract the required SAS address range for the entire work order from the SAS address pool after the work order is created, based on the number of work orders and the maintained SAS address allocation rules for the boards.

[0023] The barcode printing and pasting module prints the corresponding S / N number segment and SAS address segment barcodes according to the work order, and pastes the S / N number segment and SAS address segment barcodes onto the PCBA board one by one;

[0024] The binding record module is used to bind each PCBA board with the S / N number segment and SAS address segment barcode, and to send back the binding relationship information as a record;

[0025] The binding relationship programming module transmits the recorded binding relationship to the programming unit and programs it into the corresponding PCBA storage chip.

[0026] The final inspection and comparison module scans the S / N and SAS tag information of each board and compares it with the binding relationship information of the binding record module. Only when the comparison results match can the final packaging be carried out.

[0027] Preferably, in the SAS address pool maintenance module, the address pool is 16C92BF000000000-16C92BFFFFFFFFFF, and the SAS address allocation rule is: the first 7 bits must be 16C92BF, and the last two bits must be 00 or 80.

[0028] Preferably, in the SAS address range allocation module, the address range and the work order board S / N are set to be bound together. After binding, SAS address and S / N number ranges outside the bound range will no longer be used to avoid confusion.

[0029] Preferably, in the binding record module, if any S / N number segment or SAS address is not opened by the work order, the binding relationship cannot be established and an error signal is issued; thus achieving first-level error prevention.

[0030] Preferably, in the final inspection comparison module, the S / N and SAS tag information of each board is scanned, and the binding relationship between the acquired information and the record is compared. If the comparison results are consistent, the process proceeds to the packaging process. If the comparison results are inconsistent, the cause is analyzed and corrected.

[0031] This invention also provides a method for controlling the production process of allocating SAS addresses in PCBA, comprising the following steps:

[0032] Step S1: The step of maintaining the SAS address pool is used to maintain the SAS address pool before the PCBA work order is issued, and to maintain the number and rules of SAS addresses that need to be allocated to each PCBA board.

[0033] Step S2: The SAS address range allocation step is used to extract the required SAS address range for the entire work order from the SAS address pool after the work order is created, based on the number of work orders and the maintained SAS address allocation rules for the boards.

[0034] Step S3: Barcode printing and pasting steps. Print the corresponding S / N number segment and SAS address segment barcodes according to the work order, and paste the S / N number segment and SAS address segment barcodes one by one onto the PCBA board;

[0035] Step S4: The binding record step, used to bind each PCBA board with the S / N number segment and SAS address segment barcode, and to send the binding relationship information back to the record;

[0036] Step S5: The binding relationship is recorded by transmitting the recorded binding relationship to the recording unit and recording it into the corresponding PCBA memory chip.

[0037] Step S6: Final inspection and comparison step. Scan the S / N and SAS tag information of each board and compare it with the binding relationship information in the binding record step. Only when the comparison results are consistent can the final packaging be carried out.

[0038] Preferably, in step S1, the address pool is 16C92BF000000000-16C92BFFFFFFFFFF, and the SAS address allocation rule is: the first 7 bits must be 16C92BF, and the last two bits must be 00 or 80.

[0039] Preferably, in step S2, the address range and the work order board S / N are bound together. After binding, SAS addresses and S / N number ranges outside the bound range will no longer be used to avoid confusion.

[0040] Preferably, in step S4, if any S / N number segment or SAS address is not opened by the work order, the binding relationship cannot be established, and an error signal is issued; thus achieving first-level error prevention.

[0041] Preferably, in step S6, the S / N and SAS tag information of each board is scanned, and the obtained information is compared with the binding relationship of the records. If the comparison results are consistent, the process proceeds to the packaging process. If the comparison results are inconsistent, the cause is analyzed and corrected.

[0042] The beneficial effects of this invention are that it effectively overcomes the drawbacks of the SAS address control process. By changing the existing approach to production line printing control, it achieves SAS address control through system logic error prevention. The pre-processing station completes the SAS barcode pasting and binding action before the board goes online, effectively improving production line efficiency. Through a two-level error prevention control process, it completely avoids the risk of incorrect SAS address pasting or binding due to operator error, thereby improving product quality and increasing production line efficiency.

[0043] Furthermore, the design principle of this invention is reliable, the structure is simple, and it has a very wide range of application prospects.

[0044] Therefore, it is evident that the present invention has outstanding substantive features and significant progress compared with the prior art, and the beneficial effects of its implementation are also obvious. Attached Figure Description

Obviously, the drawings described below are only embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0047] Figure 2 This is a flowchart of a management method for PCBA SAS address allocation production process provided by the present invention.

[0048] The modules are: 1-Maintain SAS address pool module, 2-SAS address segment allocation module, 3-Barcode printing and pasting module, 4-Binding record module, 5-Binding relationship burning module, and 6-Final inspection and comparison module. Detailed Implementation

[0049] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following implementation methods.

[0050] like Figure 1 As shown in the figure, this embodiment provides a management and control system for PCBA SAS address allocation production process, including:

[0051] The SAS address pool maintenance module 1 is used to maintain the SAS address pool before the PCBA work order is issued, and to maintain the number and rules of SAS addresses that need to be allocated to each PCBA board; in the SAS address pool maintenance module 1, the address pool is 16C92BF000000000-16C92BFFFFFFFFFF, and the SAS address allocation rule is: the first 7 bits must be 16C92BF, and the last two bits must be 00 or 80.

[0052] The SAS address segment allocation module 2 is used to extract the required SAS address segment for the entire work order from the SAS address pool after the work order is created, based on the number of work orders and the maintained SAS address allocation rules for the boards. In the SAS address segment allocation module 2, the address segment and the S / N of the work order board are set to be bound together. After binding, SAS address and S / N number segments outside the bound range will no longer be used to avoid confusion.

[0053] Barcode printing and pasting module 3 prints the corresponding S / N number segment and SAS address segment barcodes according to the work order, and pastes the S / N number segment and SAS address segment barcodes onto the PCBA board one by one;

[0054] The binding record module 4 is used to bind each PCBA board with the barcode of the S / N number segment and SAS address segment, and to transmit the binding relationship information back and record it. In the binding record module 4, if any S / N number segment or SAS address is not opened by the work order, the binding relationship cannot be realized and an error signal is issued; thus achieving first-level error prevention.

[0055] The binding relationship programming module 5 transmits the recorded binding relationship to the programming unit and programs it into the corresponding PCBA storage chip;

[0056] The final inspection and comparison module 6 scans the S / N and SAS tag information of each board and compares it with the binding relationship information in the binding record module. Only when the comparison results match can the final packaging process begin. In the final inspection and comparison module 6, the S / N and SAS tag information of each board is scanned, and the acquired information is compared with the recorded binding relationship. If the comparison results match, the process proceeds to the packaging stage; if the comparison results do not match, the cause is analyzed and corrected.

[0057] Example 2:

[0058] like Figure 2 As shown in the figure, this embodiment provides a method for controlling the production process of PCBA SAS address allocation, which includes the following steps:

[0059] Step S1: The step of maintaining the SAS address pool is used to maintain the SAS address pool before the PCBA work order is issued, and to maintain the number and rules of SAS addresses that need to be allocated to each PCBA board; in step S1, the address pool is 16C92BF000000000-16C92BFFFFFFFFFF, and the SAS address allocation rule is: the first 7 bits must be 16C92BF, and the last two bits must be 00 or 80.

[0060] Step S2: The SAS address range allocation step is used to extract the required SAS address range for the entire work order from the SAS address pool after the work order is created, based on the number of work orders and the maintained SAS address allocation rules for the boards. In step S2, the address range and the S / N of the work order board are bound together. After binding, SAS address and S / N number ranges outside the bound range will no longer be used to avoid confusion.

[0061] Step S3: Barcode printing and pasting steps. Print the corresponding S / N number segment and SAS address segment barcodes according to the work order, and paste the S / N number segment and SAS address segment barcodes one by one onto the PCBA board;

[0062] Step S4: The binding record step is used to bind each PCBA board with the barcode of the S / N number segment and SAS address segment, and to return the binding relationship information to the record; in step S4, if any S / N number segment or SAS address is not opened by the work order, the binding relationship cannot be achieved and an error signal is issued; thus achieving first-level error prevention.

[0063] Step S5: The binding relationship is recorded by transmitting the recorded binding relationship to the recording unit and recording it into the corresponding PCBA memory chip.

[0064] Step S6: Final inspection and comparison step. Scan the S / N and SAS tag information of each board and compare it with the binding relationship information in the binding record step. Only when the comparison results are consistent can the final packaging be carried out.

[0065] In step S6, the S / N and SAS tag information of each board is scanned, and the obtained information is compared with the binding relationship of the records. If the comparison results are consistent, the process proceeds to the packaging process. If the comparison results are inconsistent, the cause is analyzed and corrected.
