DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0019] As Figures 1 to 4As shown, the size detection platform for home decoration assembly boards of the embodiment includes platform support 1, measurement platform 2, longitudinal electric guide rail 4, transverse electric guide rail 12, longitudinal grating ruler 3, transverse grating ruler 8, camera support 10, area array camera 9, telecentric lens 13, ring light source 14, and upper computer and other components.

[0020] The platform support serves as the basic support structure of the entire device, ensuring the stability of the entire detection platform during the working process and providing a reliable basis for subsequent accurate measurement. The measurement platform 2 is used to place the home decoration assembly boards to be detected, and its surface is smooth and flat, reducing interference with the placement and measurement of the boards. The longitudinal electric guide rail 4 is installed on both sides of the short side of the measurement platform 2, enabling precise movement of the camera and other components through the electric guide rail when measuring the length and width of the boards, thereby achieving comprehensive size detection. The longitudinal electric guide rail moving head 5 on the longitudinal electric guide rail 4 is a key component for realizing guide rail movement, which is connected to both ends of the transverse electric guide rail 12, ensuring the coordination of movement in both directions.

[0021] The longitudinal grating ruler 3 is arranged parallel to each side of the longitudinal electric guide rail 4, with its scale parallel to the outside of the longitudinal electric guide rail 4, used for accurately measuring the displacement of the longitudinal electric guide rail moving head 5. The longitudinal grating ruler reading head 16 is connected to the longitudinal electric guide rail moving head 5, which converts mechanical displacement into electrical signals by reading the scale information of the grating ruler and feeding back to the upper computer. The upper computer uses these data to perform accurate position calculation, thereby determining the size information of the boards in the length direction, with a measurement accuracy of 0.005 mm, providing a strong guarantee for high-precision detection.

[0022] The transverse electric guide rail 12 is installed on the transverse support beam 7, which is connected to the longitudinal electric guide rail moving heads 5 on both sides through the connecting piece 6, constructing a stable two-dimensional motion frame. The transverse grating ruler 8 is arranged parallel to the transverse electric guide rail 12, with its reading head connected to the camera support 10, also used for accurately measuring the displacement of the camera support 10 in the transverse direction, providing accurate data support for measuring the width of the boards.

[0023] The camera support 10 is used to fix the area array camera 9 and connect the transverse grating ruler reading head 17, ensuring the stability and position accuracy of the camera during movement. The area array camera 9 is connected to the telecentric lens 13, which can effectively reduce image distortion and obtain clear and accurate board edge images, providing reliable image data for subsequent size calculation. The ring light source 14 is located below the telecentric lens 13, with its unique ring structure and the function of automatically adjusting the light direction according to the edge angle of the board to be measured, which can overcome the shadow and reflection interference caused by the reflection characteristics and angle differences of the board surface, ensuring that the board edge can be clearly presented during shooting at each detection point, improving the reliability and accuracy of edge detection.

[0024] The host computer is connected with the driving motors of the transverse electric guide rail 12 and the longitudinal electric guide rail 5, the image acquisition card of the area array camera 9 and the light source controller of the ring light source 14 through the microcontroller. The host computer can control the movement of the electric guide rail according to the preset program, realize the automatic detection process, receive and process the image data collected by the area array camera 9, calculate the size parameters of the plate in combination with the data of the grating ruler, and control the light-emitting state of the ring light source 14 according to the detection requirements, so as to optimize the detection environment.

[0025] When the size detection platform is used, first, the power supply of the equipment is turned on, the host computer is started and initialized, the guide rail heads return to the original position, the camera and the light source are self-checked. Then the home decoration assembled plate to be detected is placed in the detection area of the measuring platform 2, and the standard values such as the length, width and angle of the plate are input in the host computer. The host computer controls the longitudinal electric guide rail 4 and the transverse electric guide rail 12 to move, drives the camera bracket 10, the area array camera 9, the telecentric lens 13 and the ring light source 14 to the first detection point of the edge of the plate, adjusts the light-emitting direction of the ring light source 14, the area array camera 9 takes a picture, the host computer receives the image data and reads the data of the grating ruler reading head for recording. Then the other detection points of each edge of the plate are detected in sequence according to the preset program, until the data collection of all detection points is completed. The host computer processes and analyzes the collected data, compares and calculates the actual measurement value with the standard value, obtains the size deviation of the plate, judges whether the plate is qualified, finally displays the detection result on the host computer interface, and the equipment automatically resets to standby state after the detection is completed.

[0026] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
