Description

Technical Field

[0001] The present invention relates to the technical field of vacuum lamination, and particularly to an automated code scanning and loading lamination method for a vacuum laminator.

Background Art

[0002] Printed circuit boards are used to load various electronic components. With the trend of miniaturization and high-density assembly of electronic components, coupled with a large number of complex connection lines derived from densification, the installation area on the circuit board is no longer sufficient. Therefore, multi-layer substrates have been developed, which are formed by stacking and laminating multiple layers of plates. When laminating multiple layers of plates, a laminator is required. Lamination is an important link in the production of metal substrates. Existing vacuum laminators can apply high temperature and high pressure to the stacked and aligned multi-layer plates, causing the adhesive between layers to melt under high temperature, and then strengthening the connection by high pressure and expelling the residual gas in the interlayer. It can also make the temperature and pressure distribution uniform and improve the exhaust effect by evacuating the vacuum. The operating state of the vacuum laminator directly affects the quality of the laminated materials. Different lamination programs need to be selected when laminating different plates to meet the lamination requirements. However, the lamination programs of existing vacuum laminators are mostly manually selected by operators by clicking. This selection method is cumbersome to operate and prone to misclicking, and there is a risk of incorrect program selection and damage to the laminated parts.

Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the prior art and propose an automated code scanning and loading lamination method for a vacuum laminator, which can select the lamination program by scanning the code, is convenient to select the program, is not easy to select wrongly, and performs visual recognition for secondary verification to improve safety.

[0004] To achieve the above purpose, the present invention proposes an automated code scanning and loading lamination method for a vacuum laminator, including a code scanning device and a number of barcodes corresponding to the code scanning device. The code scanning device is electrically connected to the vacuum laminator. Each barcode is respectively configured with a corresponding lamination program. When the code scanning device scans the corresponding barcode, the vacuum laminator recognizes the content of the barcode and executes the corresponding lamination program;

[0005] A phase-taking device is also provided at the loading position of the vacuum laminator. The vacuum laminator has a built-in visual recognition unit. Visual features of various materials are preset in the visual recognition unit. The phase-taking device is used to collect the material image of the lamination area before the vacuum laminator performs lamination. The barcode is also configured with corresponding material information. The visual recognition unit retrieves the corresponding material visual features according to the material information obtained after the code scanning device scans the code and compares them with the current material image of the lamination area to determine whether they are the same material. If so, the vacuum laminator executes the lamination program; if not, the vacuum laminator pauses the execution of the lamination program and outputs an alarm message.

[0006] Preferably, before the vacuum laminating machine executes the laminating process, if the image acquisition device fails to capture the material image in the laminating area, the vacuum laminating machine pauses the execution of the laminating process and outputs an alarm message.

[0007] Preferably, various visual features after the lamination of various materials are also preset in the visual recognition unit. After the laminating process of the vacuum laminating machine is completed, the image acquisition device captures the material image after lamination again, and the visual recognition unit compares the material image after lamination with the preset visual features of the material after lamination to determine whether the material after lamination is qualified.

[0008] Preferably, the barcode contains a program download link. After the barcode is scanned by the barcode scanning device, the corresponding program is automatically downloaded and executed.

[0009] Preferably, the barcode includes a general user QR code and an administrator QR code. The general user QR code and the administrator QR code have different permissions. Scanning the general user QR code can only control the vacuum laminating machine to execute a predetermined program, and the debugging interface can be called or the system and program parameters can be modified when scanning the administrator QR code.

[0010] Preferably, the barcode adopts a hierarchical encryption structure. The outer layer is a plaintext program identifier, and the inner layer parameters are encrypted by AES and decrypted by a preset key.

[0011] Preferably, the visual recognition unit retrieves the corresponding material visual features according to the material information obtained after the barcode scanning device scans the barcode and compares them with the material image in the current laminating area to determine whether they are the same material. If the result is negative, the visual recognition unit compares with all the preset visual features of various materials to determine whether there is a corresponding material. If there is, the user is asked whether to execute the corresponding material program or continue to execute the barcode scanning program; if not, the vacuum laminating machine pauses the execution of the laminating process, outputs an alarm message, and asks the user whether to continue to execute the barcode scanning program.

[0012] Preferably, the barcode is configured with corresponding operator information. When the barcode is scanned to execute the laminating process, the laminating operation is recorded and the corresponding operator information is recorded.

[0013] Advantages of an automated barcode scanning, loading, and pressing method for a vacuum pressing machine in the present invention: By providing a barcode scanning device to cooperate with barcodes, corresponding pressing programs are selected through scanning and identifying barcodes, realizing automated barcode scanning and loading of pressing programs, improving the degree of automation, making operation more convenient, avoiding damage and scrapping of pressed panels caused by incorrect selection of pressing programs by operators, with a foolproof operation that enables operators to get started faster. By providing an industrial camera and a visual recognition unit to cooperate, secondary verification protection is provided for the vacuum pressing machine. Before pressing, the appearance of the pressed panel is identified through visual recognition technology to check whether it corresponds to the appearance of the selected pressing program panel, thus avoiding incorrect barcode scanning by operators resulting in incorrect selection of pressing programs. With secondary verification, it has higher safety and is more convenient to use, and the visual recognition process is fully automated with a high degree of automation.

[0021] Embodiment 1:

[0022] Refer to Figure 1 , an automated scanning code loading and pressing method for a vacuum laminating machine of the present invention includes a scanning code device 1 and a plurality of barcodes corresponding to the scanning code device 1. In this embodiment, two-dimensional codes in the barcodes are used, and the scanning code device 1 uses a barcode scanner. The scanning code device 1 is electrically connected to the vacuum laminating machine. Each of the barcodes is respectively configured with a corresponding pressing program. When the scanning code device 1 scans the corresponding barcode, the vacuum laminating machine recognizes the content of the barcode and executes the corresponding pressing program. In this embodiment, by setting the cooperation between the scanning code device 1 and the barcodes, and selecting the corresponding pressing program by scanning and recognizing the barcodes, the automated scanning code loading and pressing program is realized, the degree of automation is improved, the operation is more convenient, the damage and scrapping of the pressed plate caused by the wrong selection of the pressing program by the operator are avoided, and it is a fool-proof operation, making it easier for the operator to get started.

[0023] Among them, the barcode contains a program download link. After the scanning code device 1 scans the barcode, the corresponding program is automatically downloaded and executed. It is convenient to obtain the pressing program.

[0024] The barcode includes a common user QR code and an administrator QR code. The common user QR code and the administrator QR code have different permissions. Scanning the common user QR code can only control the vacuum press to execute a predetermined program. Scanning the administrator QR code can call the debugging interface or modify the system and program parameters. The permission classification can facilitate the management of the equipment and prevent ordinary operators from modifying the system or pressing program by mistake.

[0025] In order to improve security, the barcode adopts a layered encryption structure, in which the outer layer is a plain text program identifier, and the inner layer parameters are encrypted by AES and decrypted by a preset key.

[0026] In order to facilitate tracing, the barcode is configured with corresponding operator information. When the barcode is scanned to execute the pressing program, the pressing operation and the corresponding operator information are recorded. The recorded information is saved to facilitate tracing after problems are found later.

[0027] Embodiment 2:

[0028] Based on the first embodiment, refer to Figure 1 , a photographing device 2 is also provided at the loading position of the vacuum press machine, and the photographing device 2 is an industrial camera. The built-in visual recognition unit of the vacuum press machine has visual features of various materials preset in the visual recognition unit. The photographing device 2 is used to collect the material image of the pressing area before the vacuum press machine presses, and the barcode is also configured with corresponding material information. The visual recognition unit retrieves the corresponding material visual features according to the material information obtained after the code scanning device 1 scans the code and compares it with the image of the pressed plate in the current pressing area to determine whether it is the same material. If so, the vacuum press machine executes the pressing program; if not, the vacuum press machine pauses the pressing program and outputs an alarm message. In this embodiment, an industrial camera and a visual recognition unit are arranged to cooperate to provide secondary verification protection for the vacuum press machine. Before pressing, the visual recognition technology is used to identify whether the pressed plate corresponds to the appearance of the selected pressing program plate, thereby avoiding the operator's scanning error causing the pressing program to be selected incorrectly. The secondary verification is safer and more convenient to use, and the visual recognition process is fully automatic with a high degree of automation.

[0029] In order to avoid the occurrence of the phenomenon of equipment mis-starting, before the vacuum laminating machine executes the laminating program, if the camera 2 does not capture the material image in the laminating area, the vacuum laminating machine will suspend the laminating program and output an alarm message. This method can prevent the vacuum laminating machine from being mis-started when the material is not loaded, avoid damage to the equipment, and avoid wasting energy.

[0030] Specifically, after the visual recognition unit obtains the material information scanned by the code scanning device 1, it retrieves the corresponding visual features of the material and compares them with the material image in the current pressing area to determine whether they are the same material. If the result is negative, the visual recognition unit compares with the visual features of all preset materials to determine whether there is a corresponding material. If there is, the user is asked whether to execute the corresponding material program or continue to execute the code scanning program. If not, the vacuum press pauses the execution of the pressing program, outputs an alarm message, and asks the user whether to continue executing the code scanning program. This step can facilitate the operator to adjust the pressing program when problems are found and enable rapid adjustment.

[0031] Embodiment 3:

[0032] Based on Embodiment 2, the visual recognition unit also presets the visual features of various materials after pressing. After the pressing program of the vacuum press is executed, the imaging device 2 collects the image of the pressed material again, and the visual recognition unit compares the image of the pressed material with the preset visual features of the material after pressing to determine whether the pressed material is qualified. This step can perform visual inspection on the finished product after pressing to detect whether the finished product is qualified. Some finished products with obvious appearance defects can be found through visual inspection, which is convenient for discovering problems in a timely manner.

[0033] Working process of the present invention:

[0034] In the working process of the automatic code scanning, loading and pressing method for a vacuum press of the present invention, before performing the pressing operation, the corresponding barcode is scanned by the code scanning device 1. When the code scanning device 1 scans the corresponding barcode, the vacuum press recognizes the content of the barcode and executes the corresponding pressing program.
