Description

However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0044] It should be understood that, although the terms first, second, etc. may be used to describe various information in one or more embodiments of the present application, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0045] In the present application, a plate quality detection device is provided, which is described in detail in the following embodiments.

[0046] Figure 1 A schematic diagram of a plate quality detection device according to an embodiment of the present application is shown, which specifically includes a detection camera module 1, a camera displacement module 2, a scanning module 3, a side module 4, a plate transport module 5 and a data processing module 6, wherein:

[0047] The plate transport module 5 is used to transport the plates to be tested;

[0048] The scanning module 3 is arranged at the front section of the plate transport module 5, and is used to scan the identity code of the plate to be detected, and send the identity code to the data processing module 6;

[0049] The data processing module 6 determines the plate type of the plate to be detected according to the identity code, determines the plate size according to the plate type, and sends the plate size to the side module 4 and the camera displacement module 2;

[0050] The side module 4 is disposed between the scanning module 3 and the detection camera module 1, and adjusts the position of the plate to be detected on the plate transport module 5 according to the size of the plate;

[0051] The camera displacement module 2 adjusts the position of the detection camera module 1 according to the size of the plate;

[0052] The detection camera module 1 is arranged in the middle section of the plate detection module, and is used to collect image information of the plate to be detected, and send the image information to the data processing module 6 for data analysis to determine the plate quality data of the plate to be detected.

[0053] The plate transport module 5 adopts a conveyor belt structure; the plate to be inspected includes an identity code, which can be a barcode or a QR code. By scanning and identifying the identity code, the plate type of the corresponding plate to be inspected can be determined. In addition, the detection camera module and the camera displacement module can be integrated. Figure 1 A device schematic diagram of a plate quality detection device is provided.

[0054] Based on this, the plate to be inspected is transported by the plate transport module 5 of the conveyor belt structure, and in order to ensure the inspection efficiency, the transport speed of the plate transport module 5 of the conveyor belt structure is above 1m / s; when the plate to be inspected passes through the scanning module 3, the scanning module 3 scans the identity code of the plate to be inspected, and sends the identity code to the data processing module 6 for data processing. The data processing module 6 determines the plate type of the plate to be inspected according to the identity method, further queries the plate size corresponding to the plate type, and sends the query result to the side module 4 and the camera displacement module 2.

[0055] When the plate to be inspected arrives at the side module 4, the side module 4 determines the ideal position of the plate to be inspected according to the plate size and the width of the plate transport module 5, and moves the plate to be inspected to the ideal position; thereafter, before the plate to be inspected arrives at the detection camera module 1, the camera displacement module 2 determines the ideal position of the camera in the detection camera module 1 according to the ideal position determined above and the plate size, and moves the camera in the detection camera module 1 to the ideal position of the camera. The ideal position is the camera in the camera module, and the distance between its camera lens and the plate to be inspected is the position corresponding to the focal length of the camera.

[0056] When the plate to be inspected arrives at the inspection camera module 1, the inspection camera module 1 collects image information of the plate to be inspected. The data processing module 6 determines whether there are scratches on the plate to be inspected, whether the edge sealing is damaged, the actual size, shape, color difference and other information based on the image information, and summarizes the plate quality data.

[0057] Furthermore, the detection camera module 1 includes a front and rear camera group 11, a top camera 12, a bottom camera group 13, and a left and right camera group 14, wherein the front and rear camera group 11 uses a surface scanning camera to capture the front and rear sides of the plate to be detected; the top camera 12 uses a line scanning camera to capture the upper surface of the plate to be detected; the bottom camera group 13 uses a line scanning camera to capture the lower surface of the plate to be detected; the left and right camera group 14 uses a line scanning camera to capture the left and right sides of the plate to be detected.

[0058] Based on this, Figure 2 As shown in the schematic diagram of the detection camera module and camera displacement module of a plate quality detection device provided, since the transportation speed of the plate transportation module 5 belongs to high-speed transportation, a line scanning camera with higher collection efficiency is selected for collecting image information. However, the front camera and the rear camera included in the front and rear camera groups 11 are in the same straight line with the movement direction of the plate, and it is difficult to collect data through a line scanning camera. Therefore, a surface scanning camera is used; the front camera collects image information of the front and side surfaces during the transportation of the plate to be inspected, and the rear camera collects image information of the rear and side surfaces during the transportation of the inspection plate; in addition, for the front camera and the rear camera, each is configured with a corresponding infrared sensing sensor, and when the infrared sensing sensor corresponding to the current camera detects that a plate has arrived, that is, the result of sensing the plate is from nothing to something, a collection instruction is sent to the front camera, and the front camera performs image collection, and when the infrared sensing sensor corresponding to the rear camera detects that the plate has left, that is, the result of sensing the plate is from something to nothing, a collection instruction is sent to the rear camera, and the rear camera performs image collection.

[0059] In addition, the bottom camera group 13 includes a plurality of bottom cameras, which are arranged horizontally perpendicular to the running direction of the plate to be detected, and a line scanning camera is selected to collect image information of the lower surface of the plate to be detected; and Figure 3 As shown in the schematic diagram of the bottom camera of a plate quality inspection device provided, each bottom camera includes a first rotating component and a second rotating component. The first rotating component causes the corresponding bottom camera to rotate along the running direction of the plate to be inspected, and the second rotating component causes the corresponding bottom camera to rotate along the direction of its own lens as the axis, and the first rotating component and the second rotating component both include a locking mechanism to lock the bottom camera from moving. Therefore, the user can manually adjust the direction of the bottom camera through the first rotating component, the second rotating component and the locking mechanism.

[0060] Furthermore, the camera displacement module 2 includes a top camera displacement submodule 21 and a left and right camera group displacement submodule 22, wherein the top camera displacement submodule 21 adjusts the position of the top camera 12 according to the plate thickness and plate width included in the plate size; the left and right camera group displacement submodule 22 adjusts the position of the left and right camera group 14 according to the plate width included in the plate size.

[0061] Furthermore, the top camera displacement submodule 21 includes a horizontal module 211 and a vertical module 212, wherein the vertical module 212 vertically moves the top camera 12 according to the thickness of the plate; and the horizontal module 211 horizontally moves the top camera 12 according to the width of the plate.

[0062] Furthermore, the left and right camera group displacement submodule 22 horizontally moves the cameras included in the left and right camera group 14 according to the thickness of the plate.

[0063] Among them, Figure 2 As shown in the schematic diagram of the detection camera module and camera displacement module of a plate quality detection device provided, the left and right camera groups 14 include a left camera and a right camera, which are respectively arranged on the left and right sides of the plate transport module 5, and a line scan camera is selected to respectively collect image information of the left and right sides of the plate to be detected. The top camera 12 also uses a line scan camera to collect image information of the upper surface of the plate to be detected.

[0064] And, if Figure 2 As shown in the schematic diagram of the detection camera module and camera displacement module of a plate quality detection device provided, since the left and right camera groups 14 and the top camera 12 are both line scanning cameras, and the line scanning cameras do not have an automatic focus function, the left and right camera groups 14 are arranged on the left and right camera group displacement submodules 22 of the camera displacement module 2, and the top camera 12 is arranged on the top camera displacement submodule 21 of the camera displacement module 2; the left and right camera groups 14 determine the target positions corresponding to the left camera and the right camera respectively according to the plate width and the plate transport module 5 width, and the target position is the position where the distance between its camera lens and the plate to be detected is the position corresponding to the camera focal length; similarly, the top camera 12 also has a corresponding target position, which not only ensures that the distance between the camera lens of the top camera 12 and the plate to be detected is the position of the camera focal length, but also specifies the scanning starting point of the top camera 12, specifically, as Figure 4As shown in the schematic diagram of a top camera displacement submodule of a plate quality inspection device provided, the horizontal module 211 and the vertical module 212 are both in the form of guide rails. The vertical module 212 in the top camera displacement submodule 21 vertically moves the top camera 12 according to the thickness of the plate, so that the lens of the top camera 12 is at a distance from the upper surface of the plate to be inspected, which is the focal length of the top camera 12; then the horizontal module 211 determines the scanning starting point of the top camera 12 according to the width of the plate and the width of the plate transport module 5.

[0065] Furthermore, the side module 4 includes a power unit and a side baffle, wherein the power unit provides power for the side baffle; the side baffle pushes the plate to be inspected to a predetermined position of the plate transport module 5 according to the plate width included in the plate size.

[0066] Among them, Figure 1 As shown in the device schematic diagram of a plate quality detection device provided, the side module 4 is placed after the scanning module 3 and before the detection camera module 1; the predetermined position is generally set to one side of the plate transport module 5, such as the rightmost side; according to the plate width of the plate to be detected, the positions of the left and right sides of the plate to be detected are determined when it is at the predetermined position, and the side baffle pushes the plate to be detected to the predetermined position through the power output by the power unit.

[0067] Based on this, when the predetermined position is set as the edge of the plate transport module 5, the left and right camera group displacement submodule 22 will only move the camera on the other side of the predetermined position in the left and right camera group 14. If the predetermined position is the rightmost side of the plate transport module 5, then the left and right camera group displacement submodule 22 will only move the left camera to the target position, and the right camera is preset to be at a distance from the rightmost side of the plate transport module 5 by the focal length of the right camera.

[0068] Furthermore, the plate quality detection device further comprises a shutdown module, wherein the shutdown module controls the plate transport module 5 to shut down when the plate type is not included in the preset plate type library.

[0069] Furthermore, the shutdown module controls the plate transport module 5 to shut down when the detection camera module 1 detects that the actual plate size of the plate to be detected is greater than a preset plate size threshold.

[0070] Among them, there is a situation where the size of the plate to be inspected is too large, exceeding the maximum size requirement of the plate that the plate quality inspection device can detect. In this case, in order to avoid damage to the plate quality inspection device caused by the oversized plate to be inspected, two inspections are required; the plate types that can be inspected by the plate quality inspection device are all stored in the plate type library. In the first inspection, when the scanning module 3 scans the current plate to be inspected and determines its plate type, the plate type of the current plate to be inspected appears. At this time, the shutdown module controls the plate transport module 5 to shut down.

[0071] In the second inspection, the current plate to be inspected belongs to the type of plate that can be inspected by the plate quality inspection device, but due to processing errors and other conditions, the actual plate size of the current plate to be inspected exceeds the maximum plate size that can be detected by the plate quality inspection device, that is, the plate size threshold. The shutdown module also controls the plate transport module 5 to shut down.

[0072] Furthermore, the plate quality inspection device further includes an upper cleaning module 7 , wherein the upper cleaning module 7 is disposed above the plate transport module 5 to blow air toward the plate transport module 5 .

[0073] Furthermore, the plate quality inspection device further includes a lower cleaning module 8 , wherein the lower cleaning module 8 is disposed below the plate transport module 5 and is adjacent to the plate transport module 5 .

[0074] Among them, Figure 1 As shown in the schematic diagram of a board quality inspection device provided, the upper cleaning module 7 removes dust, impurities, wood chips and other stains on the board to be inspected by blowing air to the board transport module 5, ensuring that the image information collected will not cause errors in the data analysis results of the data processing module due to stains. In addition, the lower cleaning module can be composed of sponges, cloths, etc., which are below the board transport module 5 and will not affect the transportation of the board to be inspected above, and clean the board transport module 5.

[0076] The components of the data processing module 6 include but are not limited to a memory and a processor. The processor and the memory are connected via a bus, and the database is used to store data.

[0077] The data processing module 6 also includes an access device that enables the data processing module 6 to communicate via one or more networks.
