Abstract
Description
Technical Field
[0001] This invention relates to the field of industrial automation technology, specifically to a method and system for scheduling and prompting loading and unloading of a flying probe testing machine. Background Technology
[0002] Semi-automatic flying probe testers are widely used in circuit board testing. These machines require manual loading and unloading by the operator. Existing technologies, such as the indicator light system of this equipment, use simple light states, such as flashing or off, to indicate whether a board is being loaded or unloaded. For example, when the remaining testing time for the board under test is approximately 20% and there are no boards in the loading area, the board loading indicator light will flash to indicate that a board needs to be loaded.
[0003] However, existing technologies have significant limitations: 1. Inflexible prompting strategy: Fixed time thresholds cannot adapt to the differences in testing cycles for different board types, nor can they take into account the varying efficiency of individual operators. For complex boards with long testing times, a 20% time threshold advance is too long, causing operators to wait too early; for simple boards, the prompt is too late.
[0004] 2. Limited Information Dimensions: Only qualitative prompts indicating the required action are provided, lacking quantitative information on urgency or specific timeframes. Operators cannot determine whether tasks require immediate attention or can be completed later, making it difficult to rationally allocate multiple tasks.
[0005] 3. System isolation: The prompting logic only depends on the internal state of a single machine and cannot coordinate with other links in the production line, such as the material supply capacity of the previous process and the receiving capacity of the next process. This will cause waiting or accumulation between processes and become a bottleneck in the production line.
[0006] Therefore, there is an urgent need in this field for an intelligent scheduling solution that can achieve accurate prediction, personalized prompts, and collaboration with production systems. Summary of the Invention

Obviously, the described exemplary embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] See Figure 1 As shown in the embodiment of the present invention, a method for scheduling and prompting the loading and unloading of a flying probe testing machine is provided. The method includes the following steps: Step S10: Collect production data of the flying probe tester in real time. The production data includes at least: the equipment operating status of the flying probe tester, the number of boards to be tested in the machine, the identification of the current test board type, the board status in the feeding area, the board status in the receiving area, and the operator's identity information.
[0036] In this step, when collecting production data from the flying probe tester in real time, the status of the boards in the feeding area and receiving area is achieved through visual recognition cameras deployed in the corresponding areas. The collection steps include: analyzing the images captured by the cameras in real time through an image recognition model to determine whether there are boards in the feeding area and the number of boards in the receiving area.
[0037] For example, in the real-time acquisition of production data from the flying probe tester, the current test board type is "BGA-001", and the number of boards to be tested inside the machine is... The visual recognition camera captures images of the feeding area, which are then analyzed using the YOLOv5 model to determine... (No plate); Image analysis of the receiving area yielded...

The update formula is as follows: In the formula, For plate type Updated average test time For plate type Average test time before the update This represents the actual testing time of the latest completed board. This is a smoothing factor, with a value range of (0,1). For panel type identification; Based on formula Calculate the estimated remaining test time, where, This indicates the estimated remaining testing time. Indicates the number of boards to be tested inside the machine; Indicates plate type The average test time.
[0040] In this embodiment, the calculation of the personalized prompt threshold when calculating the dynamic decision parameters that trigger the loading / unloading prompt includes the following steps: Identify the current operator; Query the operator's historical response time data, and calculate the average response time and standard deviation; Based on personalized threshold formula Calculate the personalized prompt threshold, where, The preset safety factor is set to 1.

[0041] In this step, the remaining test time is estimated. The average test time for the board type is dynamically updated using an exponentially weighted moving average algorithm. For example, for board type "BGA-001", the average test time is... =120 seconds, new actual measurement =118 seconds, smoothing factor =0.2, then =0.2×118+0.8×120=119.6 seconds. =5 × 119.6 ≈ 598 seconds. Among these, the personalized prompt threshold... During calculation, the operator Historical average response time =90 seconds, standard deviation =15 seconds, safety factor =1, then =90 + 1 × 15 = 105 seconds. If this is the first test of the plate type, Use the standard value of 120 seconds; when the operator is a new employee. Larger, such as 120 seconds, The corresponding increase.
[0042] Step S30: Compare the estimated remaining test time with the personalized prompt threshold, and generate corresponding loading and unloading prompt instructions based on the board status of the feeding area and receiving area.

[0044] In this embodiment, the board ejection prompt logic is coordinated with the downstream process status, including the following steps: Collect the equipment status for the next process; If the next process is in a "busy" state, a delay threshold is applied. Make a judgment, among which Only if the following conditions are met: there are boards in the receiving area and Only then will a board prompt command be generated; If the next process status is "idle" or "normal", then the personalized prompt threshold will be used directly. Make a judgment.
[0045] In this embodiment, when generating the corresponding loading / unloading prompt instruction, the urgency of the prompt is also calculated, wherein: The formula for calculating the urgency of a board entry notification is as follows: ;
[0046] Based on the numerical range of the urgency (U), the prompt instructions are divided into different intensity levels; The formula for calculating the delay threshold of the board notification decision is as follows: In the formula, The urgency level is indicated for the board entry, dimensionless, and its value ranges from [0,1]. This is the dynamic delay threshold. This is a delay factor; when the next process is busy, .
[0047] For example, when Reduced to 150 seconds, less than =157.5 seconds, and =When "Busy" is active, the system triggers a board notification, and the command strength is determined according to... Classification.

This refers to the number of circuit boards in the receiving area. This represents the actual number of circuit boards in the receiving area obtained through visual recognition.

Number of test boards inside the machine Identification of the current test board type , Status of the circuit boards in the feeding area , Status of the receiving area's circuit boards Operator identity information The set of equipment operating states is as follows: Let the set of equipment states for the next process be: The trigger condition for the board entry prompt is: ; The trigger condition for the board exit notification is: ,in, ,and The prompting device is controlled to provide prompts according to the prompting instructions.
[0054] For example, when the board prompts, and At the specified time, the LED ring of the board output indicator flashes slowly, and the display shows +2; the audio unit emits a normal rhythmic cue; when the board input cue is activated, when... and At a certain time, the LED ring of the board entry indicator group flashes rapidly, among which, due to A value of ≈0.05 indicates a low urgency level. The display shows "-2", meaning that material needs to be added in approximately 2 minutes.
