[0002] The manufacturing process of circuit boards includes a variety of processes, and each process relies on various production equipment. For the main production equipment, the utilization rate of the circuit boards is usually counted to evaluate the working time and production capacity of the production equipment.

[0003] At present, the main way to count the utilization rate of circuit boards is to set a one-dimensional code (barcode) or two-dimensional code or other graphic code on the circuit board, configure a code reader on the production line, and when the circuit board flows through the production line, the code reader reads the graphic code on the circuit board and labels it, so as to count the utilization rate of the circuit board based on the label.

[0004] However, some circuit boards are NPI (New Product Introduction) and do not have graphic codes. Some circuit boards are vertical, horizontal or rotated due to process requirements, and the graphic codes are beyond the reading range of the code reader. These factors will cause labeling failure, resulting in low accuracy in counting the utilization rate of circuit boards, which will have an adverse impact on circuit board production. Summary of the invention

[0034] Embodiment 1

[0035] See also Figure 1 , shows a flow chart of a method for detecting the beat utilization rate of a circuit board provided by the first embodiment of the present invention. The method can be executed by a device for detecting the beat utilization rate of a circuit board. The device for detecting the beat utilization rate of a circuit board can be implemented in the form of hardware and / or software. The device for detecting the beat utilization rate of a circuit board can be configured in an electronic device, especially an EAP (Equipment Automation Programming) system. Figure 1 As shown, the method includes:

[0036] Step 101: Determine that a plurality of circuit boards are conveyed on a production line.

[0037] During the production process of circuit boards, the EAP system will generate a unique board number Pnlid for the circuit board, encode the board number Pnlid into a graphic code such as a one-dimensional code (barcode) or a two-dimensional code, and the engineer will use related production equipment to print the graphic code on the circuit board.

[0038] Among them, circuit boards include PCB (Printed Circuit Board), FPC (Flexible Printed Circuit) and other types.

[0039] Due to the existence of NPI factors, the circuit boards belonging to NPI do not have an EAP system, and these circuit boards are not configured with graphic codes such as one-dimensional codes (barcodes) or two-dimensional codes. Therefore, some or all of the circuit boards are configured with graphic codes such as one-dimensional codes (barcodes) or two-dimensional codes.

[0040] like Figure 2 As shown, a first code reader 2022 and a second code reader 2023 are arranged at different positions of the same bracket 2021 above the crawler 202 of the production line. The crawler 202 is connected to the production equipment 203, and the circuit board 201 is transported to the production equipment 203 via the crawler 202.

[0041] Among them, the first code reader and the second code reader are both code readers matching the graphic code. The first code reader and the second code reader are both advanced production lines, and can use images, infrared and other methods to read the graphic code on the circuit board.

[0042] In addition, the model of the first code reader and the model of the second code reader may be the same or different, and this embodiment does not limit this.

[0043] In actual applications, some circuit boards are placed vertically, horizontally or rotated due to process requirements. When the circuit boards are placed on the production line, the graphic code may be located in the front, back or edge (left or right) of the circuit board with the flow direction of the circuit board as the positive direction. The code reader is required to have a wider reading range, while the reading range of a code reader is relatively limited. In this embodiment, a code reader is added on the basis of the original code reader, that is, the first code reader and the second code reader are configured at the same time to increase the reading range.

[0044] The first code reader is arranged above the edge of the production line, and the second code reader is arranged above the middle of the production line. The edge of the production line of the first code reader corresponds to the edge of the graphic code on the circuit board.

[0045] So, if Figure 3 As shown, for the graphic code 303 located at the edge of the circuit board, the first code reader can basically read the code successfully. For the graphic code 301 located in front of the circuit board and the graphic code 302 located behind the circuit board, the first code reader can mostly read the code successfully, but there is a certain probability of reading failure. For the graphic code 301 located in front of the circuit board and the graphic code 302 located behind the circuit board, the second code reader can basically read the code successfully. For the graphic code 303 located at the edge of the circuit board, the second code reader can mostly read the code successfully, but there is a certain probability of reading failure.

[0046] Furthermore, the reading range of the first code reader partially overlaps with the reading range of the second code reader. For example, the reading range of a certain model of code reader is about 300 mm. When arranged in the above manner, the reading ranges of the two code readers overlap by 30 mm. Therefore, no matter whether the graphic code may be located in front of, behind or at the edge of the circuit board, at least one of the first code reader and the second code reader can basically successfully read the graphic code.

[0047] If it is determined that a plurality of circuit boards are being conveyed on the production line, the first code reader and the second code reader may be activated to read the codes simultaneously.

[0048] Step 102: Control the first code reader to scan the graphic code on the circuit board using the first mode to obtain first code reading information.

[0049] In this embodiment, the first code reader can be controlled to use a predetermined first mode to scan the graphic code on the circuit board to obtain the first code reading information.

[0050] In actual applications, the first mode is also called the crazy scanning mode, that is, the first code reader does not care about the position of the circuit board, and controls the first code reader to continuously read the graphic code on the circuit board within its reading range. When the graphic code on the circuit board enters the reading range of the first code reader, the first code reader successfully reads the graphic code; when the graphic code on the circuit board does not enter the reading range of the first code reader, the first code reader fails to read the graphic code.

[0051] If the first code reader has read the graphic code, the preset decoding algorithm can be called to transcode the graphic code into the first board number, the first timestamp can be queried from the local timer, and the first board number and the first timestamp can be recorded in the first code reading information. At this time, any data of the first code reading information (i.e., the first board number and the first timestamp) can be uploaded to the EAP system.

[0052] Furthermore, there is a certain amount of time from when the graphic code on the circuit board enters the reading range of the first code reader to when it leaves the reading range of the first code reader. The first code reader will generate a series of first code reading information. At this time, the first code reader can deduplicate the series of first code reading information and upload a valid first code reading information to the EAP system.

[0053] If the first code reader does not read the graphic code, it is determined that the first code reading information is empty, and at this time, no data is uploaded to the EAP system.

[0054] Step 103: Control the second code reader to scan the graphic code on the circuit board using the second mode to obtain second code reading information.

[0055] In this embodiment, the second code reader can be controlled to use a predetermined second mode to scan the graphic code on the circuit board to obtain the second code reading information.

[0056] In practical applications, the second mode is also called the trigger mode, that is, Figure 2 As shown, a trigger 2024 matching the second code reader 2023 is provided in the track 202 of the production line. The trigger 2024 is fixed within the reading range of the second code reader 2023. The trigger 2024 can be activated by infrared, pressure or the like, so as to detect whether there is a circuit board 201 entering the reading range of the second code reader 2023.

[0057] In the process of the circuit board triggering the trigger (i.e., the circuit board starts to trigger the trigger and stops triggering the trigger), the second code reader is controlled to read the graphic code on the circuit board within its code reading range. When the graphic code on the circuit board enters the code reading range of the second code reader, the second code reader successfully reads the graphic code; when the graphic code on the circuit board does not enter the code reading range of the second code reader, the second code reader fails to read the graphic code.

[0058] If the second barcode reader has read the graphic code, the preset decoding algorithm is called to convert the graphic code into a second board number, the second timestamp is queried, and the second board number and the second timestamp are recorded in the second barcode reading information. At this time, the second barcode reading information (i.e., the second board number and the second timestamp) can be uploaded to the EAP system.

[0059] Furthermore, in the process of the circuit board triggering the trigger (i.e., the circuit board starts triggering the trigger to stops triggering the trigger), there is a certain amount of time from the graphic code on the circuit board entering the reading range of the second code reader to leaving the reading range of the second code reader. The second code reader will generate a series of second code reading information (i.e., the second board number and the second timestamp). At this time, the second code reader can deduplicate the series of second code reading information and upload a valid second code reading information to the EAP system.

[0060] If the second code reader does not read the graphic code, an unread tag Noread is generated, which indicates that the graphic code is not read. The second timestamp is queried, and the unread tag and the second timestamp are recorded in the second code reading information. At this time, the second code reading information (i.e., the unread tag Noread and the second timestamp) can be uploaded to the EAP system.

[0061] Furthermore, in the process of the circuit board triggering the trigger (i.e., the circuit board starts triggering the trigger to stops triggering the trigger), the second barcode reader will generate a series of second barcode reading information (i.e., the unread label Noread and the second timestamp). At this time, the second barcode reader can deduplicate the series of second barcode reading information and upload a valid second barcode reading information to the EAP system.

[0062] In the process of the circuit board triggering the trigger (that is, the circuit board starts triggering the trigger to stops triggering the trigger), if the second code reading information contains both the second board number and the second timestamp, as well as the unread label Noread and the second timestamp, then the unread label Noread and the second timestamp are ignored, and the second board number and the second timestamp are kept valid.

[0063] Step 104: configuring production identification information for the circuit board according to the first code reading information and the second code reading information.

[0064] For the same circuit board, the first code reader uses the first mode to scan and obtain the first code reading information, and the second code reader uses the second mode to scan and obtain the second code reading information. The first code reader and the second code reader use different modes to scan at different positions, so that there is a certain difference between the first code reading information and the second code reading information.

[0065] In practical applications, the first queue can be used to store the first code reading information of the first code reader, and the second queue can be used to store the second code reading information of the second code reader. The first code reading information in the first queue and the second code reading information in the second queue are pieced together into a code reading combination. In the same combination, production identification information is configured for the circuit board based on the difference between the first code reading information and the second code reading information, wherein the production identification information is information for uniquely identifying the circuit board on the production line.

[0066] In one embodiment of the present invention, step 104 may include the following steps:

[0067] Step 1041: If the first code reading information includes a first board number and a first timestamp, and the second code reading information includes a second board number and a second timestamp, then compare the first board number with the second board number.

[0068] Step 1042: If the first board number is the same as the second board number, a combination of the first board number and the first timestamp or a combination of the second board number and the second timestamp is configured as production identification information of the circuit board.

[0069] If the first code reading information includes the first board number and the first timestamp, and the second code reading information includes the second board number and the second timestamp, it means that both the first code reader and the second code reader read the graphic code of the circuit board, and the first board number can be further compared with the second board number.

[0070] If the first board number is the same as the second board number, the difference between the first timestamp and the second timestamp can be ignored, and the combination of the first board number and the first timestamp, or the combination of the second board number and the second timestamp, meets the requirements of being the production identification information of the circuit board. Then the combination of the first board number and the first timestamp, or the combination of the second board number and the second timestamp, can be configured as the production identification information of the circuit board.

[0071] In a specific implementation, the timestamp read last may be used as the basis, and at this time, the first timestamp is compared with the second timestamp.

[0072] If the first timestamp is greater than the second timestamp, that is, the first timestamp is later than the second timestamp, the combination of the first board number and the first timestamp can be configured as the production identification information of the circuit board.

[0073] If the first timestamp is smaller than the second timestamp, that is, the second timestamp is later than the first timestamp, the combination of the second board number and the second timestamp can be configured as the production identification information of the circuit board.

[0074] Of course, in addition to taking the last read timestamp as the standard, the first read timestamp or the average value between the first timestamp and the second timestamp may also be taken as the standard, and this embodiment does not limit this.

[0075] Step 1043: If the first code reading information includes the first board number and the first timestamp, and the second code reading information includes the unread label and the second timestamp, filter out the combination of the unread label and the second timestamp, and configure the combination of the first board number and the first timestamp as the production identification information of the circuit board.

[0076] If the first code reading information includes the first board number and the first timestamp, and the second code reading information includes the unread label and the second timestamp, it means that the first code reader reads the graphic code of the circuit board and the second code reader does not read the graphic code of the circuit board. In this way, the combination of the unread label and the second timestamp can be filtered out, and the combination of the first board number and the first timestamp can be configured as the production identification information of the circuit board.

[0077] Furthermore, the graphic code may be located at the front, back, or edge (left or right) of the circuit board, and the difference between the first timestamp of the first board number and the second timestamp of the unread tag may be different.

[0078] When the graphic code is located in front of the circuit board, the second timestamp of the unread tag is later than the first timestamp of the first board number of the current circuit board by a standard period of the circuit board, and is close to the first timestamp of the first board code of the next circuit board.

[0079] When the graphic code is located behind the circuit board, the second timestamp of the unread tag is close to the first timestamp of the first board number of the current circuit board, and is later than the first timestamp of the first board code of the next circuit board by nearly a standard period of a circuit board.

[0080] When the graphic code is located at the edge of the circuit board, the second timestamp of the unread tag is nearly half a standard cycle of a circuit board later than the first timestamp of the first board number of the current circuit board, and is nearly half a standard cycle of a circuit board earlier than the first timestamp of the first board number of the current circuit board.

[0081] In the above three cases, the unread label and the second timestamp can be compared with the first board number and the first timestamp read from the current circuit board (within the group) and the next circuit board (outside the group).

[0082] At this time, you can query the standard cycle (also known as standard beat) set for the circuit board, where standard cycle = time / (standard line speed / (width of circuit board / 1000+standard spacing between circuit boards / 100)). For a certain type of circuit board, its width is 514.0960mm, the standard line speed is 2.1m / min, the standard spacing between circuit boards is 5cm, and the time is 60min. Then, the standard cycle of the circuit board = 60 / (2.1 / (514.096 / 1000+5 / 100)) = 16.12S.

[0083] The product of the standard period and a preset ratio (such as 0.5) is calculated as the threshold.

[0084] An absolute value of the difference between the second timestamp and the first timestamp is taken to obtain a time deviation value, and the time deviation value is compared with a threshold.

[0085] If the time deviation value is less than the threshold, it means that the first board number and the unread tag both represent the same circuit board. Then the combination of the unread tag and the second timestamp can be filtered out, and the combination of the first board number and the first timestamp can be configured as the production identification information of the circuit board.

[0086] Step 1044: If the first code reading information is empty and the second code reading information includes the second board number and the second timestamp, a combination of the second board number and the second timestamp is configured as production identification information of the circuit board.

[0087] If the first code reading information is empty (i.e., the first code reading information does not exist) and the second code reading information contains the second board number and the second timestamp, it means that the first code reader did not read the graphic code of the circuit board and the second code reader read the graphic code of the circuit board. Then, the combination of the second board number and the second timestamp can be configured as the production identification information of the circuit board.

[0088] Step 1045: If the first code reading information is empty and the second code reading information includes an unread label and a second timestamp, the unread label and the second timestamp are configured as production identification information of the circuit board.

[0089] If the first code reading information is empty (i.e., there is no first code reading information) and the second code reading information includes an unread label and a second timestamp, indicating that neither the first code reader nor the second code reader reads the graphic code of the circuit board, the unread label and the second timestamp can be configured as the production identification information of the circuit board.

[0090] In this embodiment, the above four situations can be summarized as follows:

[0091]

[0092] Among them, "√" means that the barcode on the circuit board is read successfully, "×" means that the barcode on the circuit board is read unsuccessfully, " / " means empty, Pnlid1 is the first board number, Pnlid2 is the second board number, T1 is the first timestamp, and T2 is the second timestamp.

[0093] Step 105: Calculate the cycle utilization rate of the circuit board according to the production identification information.

[0094] In this embodiment, the production status of the circuit boards on the production line can be measured according to the production identification information, so as to calculate the cycle utilization rate of the circuit boards on the production line.

[0095] Furthermore, the time utilization rate and first-time pass rate of the production equipment can be statistically analyzed separately, and the product of the time utilization rate, the cycle utilization rate and the first-time pass rate can be calculated as the comprehensive utilization rate of the production equipment, so as to comprehensively evaluate the efficiency of the production equipment from the perspectives of working time and production capacity and speed.

[0096] In the specific implementation, the calculation and derivation process of the cycle utilization rate of a single circuit board is as follows:

[0097]

[0098] Among them, standard production speed = standard line speed / (board width + spacing), board width is the width of the circuit board, spacing is the standard spacing between circuit boards, and when the model of the circuit board is determined, the standard production speed is a constant.

[0099] Then, when calculating the cycle utilization rate of a single circuit board, the number of production identification information can be accumulated to obtain the actual output of the circuit board.

[0100] The time stamps of two adjacent production identifications (including the first time stamp and the second time stamp) are arranged with a time period between them, and the time periods between two adjacent production identification information are accumulated to obtain the actual cycle of the circuit board.

[0101] The ratio between the actual output and the actual cycle is calculated as the actual production speed (the unit is Pnl / min, where Pnl represents circuit board).

[0102] The standard production speed (in Pnl / min) set for the circuit board is queried locally based on the model and other parameters of the circuit board.

[0103] The ratio between the actual production speed and the standard production speed is calculated as the cycle utilization rate of the circuit board (in Pnl / min).

[0104] In the present invention, it is determined that a plurality of circuit boards are conveyed on the production line; the first code reader is controlled to use the first mode to scan the graphic code on the circuit board to obtain the first code reading information; the second code reader is controlled to use the second mode to scan the graphic code on the circuit board to obtain the second code reading information; the production identification information is configured for the circuit board according to the first code reading information and the second code reading information; the beat utilization rate of the circuit board is calculated according to the production identification information. The present invention uses the first code reader and the second code reader to read the code simultaneously, which can improve the coverage rate of the code reading range. When the circuit boards are placed arbitrarily, the code reading range can cover the circuit boards on the production line. The first code reading information read by the first code reader and the second code reading information read by the second code reader are different due to different positions and modes. The production identification information can be configured for the circuit board according to these differences, and the confidence of the production identification information is improved, thereby improving the accuracy of the statistical beat utilization rate of the circuit board and ensuring the normal production of the circuit board.
