Abstract
Description
Technical Field
[0001] This invention relates to the field of packaging substrate manufacturing technology, and specifically to an automatic expansion and contraction stacking method, apparatus, equipment, and storage medium. Background Technology
[0002] In the manufacturing process of packaging substrates, X-ray drilling is a core step in controlling expansion and contraction. Because each substrate experiences deformation or variations in processing precision during manufacturing, its expansion and contraction values differ. In subsequent mechanical drilling, different expansion and contraction data must be used for products with different expansion and contraction ranges to ensure drilling accuracy. Therefore, accurate product grouping after X-ray drilling is crucial. Expansion and contraction grouping refers to grouping products with expansion and contraction values within a specific range together so that they can be processed using the same expansion and contraction data. The accuracy of grouping directly determines the processing precision of mechanical drilling and the product yield.
[0003] Currently, the industry mainly relies on manual methods for expansion and contraction separation, or simply does not separate the stacks at all. The shortcomings of existing technologies are mainly reflected in the following aspects: (1) After the target is processed, it is sorted by hand, which is inefficient and the product is easily scratched during the operation, resulting in high quality risk. (2) Relying on manual calculation of stacking rules and data results in low accuracy and is prone to errors; (3) Inaccurate manual sorting can easily lead to low efficiency and poor dimensional accuracy during mechanical drilling, thus creating potential quality problems. (4) After the stacking is completed, the expansion and contraction data needs to be uploaded manually, which is inefficient, has a high error rate, and the process record is incomplete. Summary of the Invention

The deviation between the actual expansion and contraction value and the basic pre-expansion value is used to determine whether it is necessary to split the pile. If the result is negative, X-ray drilling is performed based on historical expansion and contraction data, and it is determined whether splitting is necessary. Based on the sorting results, the products are sorted and stacked so that the corresponding expansion and contraction data can be selected for processing in the subsequent mechanical drilling process.
[0006] In the above scheme, the method further includes: before performing the drilling operation, distributing the processing formula to the drilling machine performing the drilling operation, wherein the processing formula includes the expansion and contraction coefficient and the stacking coefficient determined based on the basic pre-expansion value or historical expansion and contraction data.

[0010] In the above scheme, the historical price fluctuation data of similar products refers to the statistical results of the actual price fluctuation values of similar products in history, including the average price fluctuation and the standard deviation of price fluctuation.
[0011] Furthermore, to achieve the above objectives, the present invention also proposes an automatic expansion and contraction stacking device, comprising: The feeding machine is configured to feed materials to the current product and read product information; A target drilling machine, connected to the feeding machine, is configured to perform target drilling operations on the current product and detect expansion and contraction information; The material feeding and sorting machine is connected to the drilling machine and is configured to sort the products according to the sorting results; The server is communicatively connected to the feeding machine, the drilling machine, and the material unloading and stacking machine, respectively.

[0014] Furthermore, to achieve the above objectives, the present invention also proposes a storage medium storing an automatic expansion and contraction program, wherein the automatic expansion and contraction program, when executed by a processor, implements the automatic expansion and contraction method as described above.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.
[0022] It should be understood that the sequence number of each step in the embodiment does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
[0023] Example 1 This application provides an automatic expansion and contraction stacking method, applied in the packaging substrate manufacturing process before the mechanical drilling process. Please refer to [link to relevant documentation]. Figure 1 The method in the embodiment includes: S1, feed materials into the product and obtain product information for the current product.
[0024] In this embodiment, during the manufacturing process of the packaging substrate in a certain factory, the expansion and contraction mainly involve the following processes: Figure 2 As shown in this embodiment, the specific method for obtaining product information in an automatic expansion and contraction stacking operation process is as follows: In this embodiment, the product (such as a packaging substrate) is fed in by a loader. During loading, the loader reads the product information by scanning the code. In this embodiment, the product information includes the product model, product batch number, product workstation code information, and unique identification information containing all of the above information (specifically, a QR code or barcode).
[0025] S2, based on product information, determines whether the current product is a first batch product.
[0026] Specifically, in this embodiment, the read product information is reported to the server. After receiving the product information, the server's logic module first determines whether the product is a "first batch product". In this embodiment, "first batch product" can be defined as whether there are similar products for which historical price fluctuation data can be referenced.
[0027] S3, if the determination is yes, then perform X-ray drilling operation based on the preset basic pre-expansion value and obtain the actual expansion and contraction value. Determine whether it is necessary to split the pile based on the deviation between the actual expansion and contraction value and the basic pre-expansion value.
[0028] Specifically, in this embodiment, if there are no similar products for which historical expansion and contraction data can be referenced, the current product is determined to be a first batch product. The server uses a preset basic pre-expansion value (in this embodiment, the basic pre-expansion value is obtained synchronously from the product process information while obtaining product information, such as basic pre-expansion expansion and contraction coefficients X 0.02% and Y 0.03%) as the benchmark expansion and contraction parameters of the current product. Then, the server sends the processing operation formula containing this parameter (including expansion and contraction coefficients, stacking coefficients, etc., such as expansion and contraction coefficients X 0.02% and Y 0.03%, stacking coefficients (X, Y): (between 0.015% and 0.025%, between 0.025% and 0.035%), (between 0.05% and 0.015%, between 0.015% and 0.025%), (between 0.025% and 0.035%, between 0.035% and 0.045%), (X or Y exceeding the above three ranges) to the X-ray drilling machine. The drilling machine performs drilling operations on the product based on the received formula parameters. After the operation is completed, the drilling machine reports the actual expansion and contraction values of the product (the expansion and contraction amount in the X and Y directions of each product) to the server. After receiving the actual expansion and contraction values, the server combines the previously used "basic pre-expansion value" and the preset stacking logic (for example, setting products with expansion and contraction deviations within ±0.05% to be grouped into one pile), performs logical calculations, and determines whether the product needs to be stacked (for example, whether its expansion and contraction value exceeds the current stacking range) and how to stack it.
[0029] S4. If the determination is negative, then perform X-ray drilling operation based on historical expansion and contraction data and determine whether splitting is necessary.
[0030] In this embodiment, if there are similar products for which historical expansion and contraction data can be referenced, it is determined that the current product is not a first batch product. The server calculates the applicable expansion and contraction value for this processing based on the historical expansion and contraction data of the product model or batch through an algorithm. The X-ray drilling machine is used to perform X-ray drilling operations and obtain the actual expansion and contraction value. The deviation between the actual expansion and contraction value and the expansion and contraction value applicable to this processing is used to determine whether it is necessary to split the batch.
[0031] S5: Based on the stacking results, the products are stacked for subsequent mechanical drilling processes to select the corresponding expansion and contraction data for processing.
[0032] In this embodiment, if it is determined that stacking is necessary, the server generates specific stacking instructions and sends them to the unloading and stacking machine connected to the drilling machine. The unloading and stacking machine moves the products to the designated stacking positions according to the instructions; in this embodiment, this specifically refers to the two qualified product stacking positions and one defective (NG) product position on the unloader. After the stacking operation is completed, the unloading and stacking machine reports the stacking results (such as product information and the final stacking position) to the server, completing the closed-loop record of this stacking operation. After stacking is completed, the corresponding expansion and contraction data can be selected for processing in subsequent mechanical drilling processes, which can improve the processing accuracy of mechanical drilling.
[0033] In summary, this embodiment provides an automatic expansion and contraction stacking method, which can realize intelligent management of expansion and contraction stacking, and improve efficiency and yield.
[0034] Example 2 This application provides an automatic expansion and contraction stacking method, which is basically the same as the method in embodiment 1, except that: In this embodiment, the intelligent handling robot AGV receives the stacking instruction issued by the server or drilling machine, and transports the current product to the corresponding stacking position of the unloading and stacking machine, such as... Figure 3 As shown.

The server is configured to execute an automatic expansion and contraction stacking method to coordinate and control the feeding machine, the drilling machine, and the material unloading and stacking machine. Additionally, this embodiment includes a display for showcasing functions. In this embodiment, the server and each device interact. Specifically, the feeding machine reports product information and expansion / contraction information; the server's logic module calculates and determines the stacking method and sends it to the drilling machine; the drilling machine performs drilling operations and detects expansion / contraction information, transmitting the stacking information to the material unloading and stacking machine; the material unloading and stacking machine performs the stacking operation and reports the stacking result to the server.

Of course, the memory can also include both internal storage units and external storage devices of an automatically expanding and shrinking device. In this embodiment, the memory is typically used to store the operating system and various application software installed on an automatically expanding and shrinking device. The memory can also be used to temporarily store various types of data that have been output or will be output.
[0039] In some embodiments, the processor may be a central processing unit (CPU), a controller, a microcontroller, a microprocessor, or other data processing chip.
