Description

Technical Field

[0001] The utility model relates to the technical field of furniture detection, and more specifically to a device for detecting surface defects of furniture panels. Background Art

[0002] Defect detection generally refers to the detection of surface defects on an object. Surface defect detection uses advanced machine vision technology to detect defects such as spots, pits, scratches, color differences, and defects on the workpiece surface. Traditional inspection methods are no longer sufficient for large-scale furniture panel surface quality inspections, so machine vision inspection technology is widely used in this field.

[0003] Patent document CN217846117U discloses a particleboard surface defect detection device comprising a frame, a conveyor mounted on the frame, and a support. The conveyor is used to move particleboards placed thereon. A camera is positioned at the top of the support, and a first light source is positioned below the support near the conveyor. This device facilitates the movement of particleboards, facilitates the identification of surface defects, and improves batch quality.

[0004] Although the device has many beneficial effects, the following problems still exist: the device lacks quick-assembly parts during use and cannot be quickly disassembled and repaired; secondly, although a conveying device is provided, after identifying defective plates, there is a lack of a rapid screening structure, and the efficiency needs to be improved, so it needs to be improved. In view of this, we propose a surface defect detection device for furniture panels. Utility Model Content

[0035] in;

[0036] The bottom of the camera bracket 110 is hung with three cameras 120 by bolts. The bottom of the camera bracket 110 is plugged with two fixing blocks 140. The top of the fixing block 140 is threadedly connected to two fixing pins 130.

[0037] The side of the conveyor belt 1 210 is plugged with a support frame 1 220 , and a control box 230 is provided on the side of the support frame 1 220 . The control box 230 is electrically connected to the camera 120 ;

[0038] A second conveyor belt 340 is provided at the bottom of the first discharge plate 310, and the side of the second conveyor belt 340 is plugged into the second support frame 350;

[0039] The side of the discharge plate 2 410 is hung and welded with the motor 1 430, and the motor 1 430 is electrically connected to the control box 230. The side of the discharge plate 2 410 is hung and matched with the conveyor belt 3 440, and the side of the conveyor belt 3 440 is plugged and matched with the support frame 3 450. The bottom of the conveyor belt 3 440 is welded and connected with the motor 2 460, and the motor 2 460 is electrically connected to the control box 230.

[0040] In some examples, when there is a PLC in the control box 230, when the PLC receives a switch signal, the motor 2 460 drives the push block 480 in front of the push rod 470 to push the discharge plate 2 410 to achieve the purpose of lifting and closing.

[0041] At the same time, in order to fix the fixing block 140 , specifically, a square groove matching the camera bracket 110 is opened on the top of the fixing block 140 , and a through groove matching the screw 150 is opened on the side of the fixing block 140 .

[0042] Furthermore, in order to facilitate the placement of the fixing pins 130, specifically, a hole matching the fixing pins 130 is opened on the top of the fixing block 140, and two fixing pins 130 are threadedly connected to the top of the fixing block 140 at equal intervals. The fixing pins 130 are made of cast copper.

[0043] It is worth noting that, in order to quickly disassemble and assemble the fixing block 140, specifically, the fixing latch 130 includes a latch housing 131, and a pin rod 132 is plugged into the interior of the latch housing 131.

[0052] Working principle:

[0053] When the device is in operation, the camera 120 in the camera assembly 100 captures the furniture panels being transported, inspecting them for surface defects. The camera bracket 110 is assembled with a fixing block 140 and a fixing pin 130. The fixing pin 130, through the combination of a pin 132 and a stopper 133, utilizes a stopper plate 134 and a spring 135 to ensure the stability and accuracy of the camera 120. The captured image data is transmitted to the control box 230, and the conveyor belt 210 on the transport assembly 200 transports the furniture panels to the bottom of the camera assembly 100 for inspection. If the furniture board is judged to be qualified, it continues to move along the conveyor belt 1 210 through the discharge plate 2 410 to the conveyor belt 3 440, and the discharge plate 2 410 is raised and lowered by the push rod 470 and the push block 480 driven by the motor 2 460; if it is judged to be a defective product, it is guided to the conveyor belt 2 340 through the discharge plate 1 310 of the transmission component 2 300, so as to achieve the results of quick disassembly and assembly and better screening effect.
