As long as the boards are larger than the first support plate, the device can be used for inspection; the inspection structure can realize the inspection of boards of different specifications and shapes along the edge of the boards, and the infrared transmitter can be used to visualize the macroscopic display of the edge of the boards, and then the camera can be used to perform imaging and analysis and inspection using the existing technology to realize visual inspection; in summary, the present invention has the following effects:

[0020] 1. The clamping limit can be adjusted for plates of different widths and lengths. During the production or testing process, there is no need to prepare a variety of different clamping devices for plates of different specifications: for example, in a furniture manufacturing factory, there will be wooden boards of various sizes, from narrow wooden boards for making small drawers to wide wooden boards for making desktops, and this equipment can be used; it is suitable for plates of various shapes such as rectangular boards, square boards and curved boards. This versatility in shape further expands the scope of application of the equipment; in the building decoration industry, curved decorative boards will be used, and this equipment can also clamp and limit them to facilitate subsequent testing and other operations.

[0021] 2. As long as the plate is larger than the first pallet, the equipment can be used for testing. This feature enables the equipment to adapt to the plate testing needs in various production scenarios. For example, on some composite material plate production lines, the size of the plate may fluctuate to a certain extent, but as long as it meets the condition of being larger than the first pallet, there is no need to worry about the equipment being unable to be used.

[0022] 3. Since there is no need to frequently replace different clamping devices to adapt to different plates, the time for equipment adjustment and replacement is reduced. The strong versatility means that companies do not need to purchase a variety of clamping devices specifically for plates of specific sizes and shapes; this can bring significant savings in equipment procurement costs, equipment storage costs, and equipment maintenance costs.

[0039] As a preferred solution, further, the push plate 54 is symmetrical to the other end of the bracket 43 and is located above the first bracket 33, and is relatively clamped to clamp the plate front and back through the fit.

[0040] Working principle:

[0041] First, according to the width of the plate, the controller 2 on the base 1 is used to adjust the control device; that is, the second hydraulic cylinder 51 in the driving detection component 56 is first driven to drive the main frame 52 to rise, and then the electric push rod 53 is driven to limit the push plate 54 through the slide bar 55 to move it to fit the middle of the front side arm of the first support plate 33 for shielding;

[0042] Then, the plate is carried by the first support plate 33 in the first support structure 3, and the front side is limited by the push plate 54; the second support structure 4 is driven according to the width of the plate, and the support seat 43 on the first support rod 42 is driven to move forward and backward by controlling the second electric slide rail 41, so as to adjust the distance between the support seat 43 and the first support plate 33;

[0043] If the width of the plate is greater than the width of the first support plate 33, it is necessary to drive the first hydraulic cylinder 45 on the bearing seat 44 to extend, and drive the second clamping assembly 47 to rise through the bearing plate 46 passing through the lifting slot 6, so that the upper wall of the second support plate 48 on the second clamping assembly 47 is at the same level as the first support plate 33, and then the lower wall of the plate is supported by the first support plate 33 and the second support plate 48, and the plate is clamped and limited by the other end of the support seat 43 and the push plate 54;

[0044] Then, the first clamping assembly 34 and the second clamping assembly 47 are driven to clamp the left and right ends of the plate, so that the middle of the plate is located on the first support plate 33 for centering and limiting; that is, the first electric slide rail 341 is driven to drive the shaft seats on both sides to move relatively, and the clamping plates 347 are used to clamp the two ends of the plate through relative movement, so that the plate moves on the first support plate 33 for centering and clamping;

[0045] If the plate is placed on the first support plate 33, the clamping plate 347 can be moved manually to cause the clamping plate 347 to rotate through the shaft 344 with the help of the first bearing 343, and after the rotation, the clamping plate 347 applies force to the spring 346 through the baffle 345 to limit the resistance;

[0046] When the plate is centered and limited, the controller 2 drives the detection structure 5 to perform detection;

[0047] The detection structure 5 operates as follows:

[0048] By controlling the extension of the second hydraulic cylinder 51, the detection assembly 56 on the main frame 52 is raised to be above the plate, and the push plate 54 is required to be pushed against the front side of the plate to limit the position; then according to the side length parameters of the plate, the first motor 561 on the main frame 52 is controlled to drive the telescopic arm 566 on the rotating seat 562 to rotate, and the irradiation position of the infrared emitter 567 is adjusted, and the starting point is set from the position of one side edge of the plate;

[0049] Then, the telescopic arm 566 is driven to rotate by the first motor 561, and the second motor 564 is driven to rotate the gear 565 at the same time. The telescopic arm 566 is driven to slide and adjust its position on the limit block 563 through the engagement of the gear 565 and the telescopic arm 566. The infrared emitter 567 can be moved along a straight line or an arc, and the irradiation spot of the infrared emitter 567 can be moved along the edge of the plate. With the help of the camera 568, an image is formed, and with the help of the infrared emitter 567, a macroscopic display detection of the edge of the plate can be achieved.

[0050] After the spacing of the brackets 43 is adjusted, the first hydraulic cylinder 45 is controlled to drive the second clamping assembly 47 to rise, so that the second support plate 48 and the first support plate 33 are horizontally relative to each other for bearing, and the rear side wall of the plate is blocked and limited by the bracket 43, and the bracket 43 is driven by the second electric slide rail 41 to move toward the push plate 54 to clamp the front and rear sides of the plate and then relax the bracket 43;

[0051] Then, the first clamping assembly 34 and the second clamping assembly 47 are driven to clamp the left and right ends of the plate and near the four corners, so that the plate is centered above the first support plate 33;

[0052] Then, the first motor 561 in the detection component 56 can be driven to drive the telescopic arm 566 to flip, and the second motor 564 can be driven to drive the telescopic arm 566 to move forward and backward on the limit block 563, so as to adjust the position of the infrared emitter 567, so that the red light emitted by the infrared emitter 567 is irradiated on the edge of the plate (set the starting position), and then the first motor 561 and the second motor 564 are controlled according to the length and width of the plate, so that the infrared emitter 567 moves along the edge of the plate, and the image is transmitted to the controller 2 with the help of the camera 568;

[0053] When the edge of the plate is irregular, the red light spot of the infrared emitter 567 will change, and then the camera 568 will capture the image and feedback it to achieve the flatness detection of the edge of the plate;

[0054] During the edge detection process, the plate has multiple edges. In order to improve the stability of the plate and the detection requirements, the first clamping assembly 34, the second clamping assembly 47 and the push plate 54 are clamped or released in cooperation with the bracket 43 to prevent the edge of the plate from being blocked.
