[0026] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0027] Example:

[0028] As attached Figure 1 To Attachment Figure 6 As shown:

[0029] The utility model provides a detection device for bending deformation of wooden panels, including a workbench 11, the workbench 11 is set up as the basis of the device, four groups of mounting holes 12 are opened on the workbench 11, a transmission component is arranged on the workbench 11, the transmission component includes a conveyor belt 21 and two groups of rotating hubs 22, the two ends of the two groups of rotating hubs 22 are rotatably arranged in the four groups of mounting holes 12, the conveyor belt 21 is arranged on the two groups of rotating hubs 22, a detection component is arranged on the top of the workbench 11, and the detection component includes a laser emitting module 31 and a laser receiving module 32, the laser emitting module 31 can emit laser, and the laser receiving module 32 can emit laser. Module 32 is located opposite to the laser emitting module 31 and is used to receive the laser emitted by the laser emitting module 31. Only when the plate to be inspected has not been bent or deformed, the emitted laser can be directly received by the laser receiving module 32. If the plate is bent, it will block part or all of the laser, thereby affecting the laser receiving module 32 from receiving the laser. By detecting the size of the received laser, it is possible to determine whether the plate is bent and the degree of bending. The laser emitting module 31 can use the KY-008 laser emitting module of the Loga brand, and the laser receiving module 32 can use the Mbitrobot laser head sensor module.

[0030] Please refer to Figure 2 , Figure 5 and Figure 6 As shown, the detection component also includes a screw slide 33. A first mounting member 34 is fixedly connected to one side of the workbench 11 by multiple sets of screws. The screw slide 33 is installed on the top of the first mounting member 34. A driving motor 39 is provided at one end of the screw slide 33. The driving motor 39 provides power for the screw slide 33, so that the movement of the shaft sleeve of the screw slide 33 can be realized, which provides the detection component with the function of adjusting the detection position.

[0031] Please refer to Figure 5 and Figure 6 As shown, a second mounting member 35 is provided on the other side of the workbench 11, and a slide rail 36 is provided on the top of the second mounting member 35. One end of the gantry 37 is connected to the slide rail 36 and can slide smoothly on the guide rail of the slide rail 36; and the other end of the gantry 37 is connected to the shaft sleeve on the screw slide 33. Through this connection relationship, when the drive motor 39 is started to drive the shaft sleeve of the screw slide 33 to move, the gantry 37 can be driven to slide synchronously in the slide rail 36 on the top of the second mounting member 35, which ensures the fine-tuning of the detection area with the size of the panel, and at the same time maintains the stable posture of the panel during the detection process, and will not affect the accuracy of the detection result due to position changes.

[0032] Please refer to Figure 6As shown, both sides of the gantry 37 are provided with mounting slots 38, one group of which is provided with a laser emitting module 31 which can be adjusted up and down, and the other group of which is provided with a laser receiving module 32 on the side close to the laser emitting module 31. Through this arrangement, the detection component can form a detection area on the conveyor belt 21. When the plate passes through this detection area, the laser emitting module 31 will emit a laser to the plate. If the plate is not bent, the laser will be directly received by the laser receiving module 32 on the opposite side; however, if the plate bends while passing through the detection area, its raised part will partially or completely block the laser, so that the laser receiving module 32 cannot or can only partially receive the laser. By judging whether the bending degree of the plate exceeds the standard based on the received laser, it can be judged whether it is qualified or not, which solves the problem that the traditional plate bending detection mainly adopts manual visual inspection, can realize quantitative detection, and improve detection accuracy and efficiency.

[0033] Please refer to Figure 3 and Figure 4 As shown, the transmission component also includes a transmission motor 23. The transmission motor 23 is installed on the workbench 11, and its main shaft is directly connected to one of the rotating hubs 22 through a synchronous wheel mechanism 24. In this way, when the transmission motor 23 is started, it will drive the rotating hub 22 to rotate through the synchronous wheel mechanism 24. Conveyor belts 21 are arranged on both sides of the rotating hub 22, and the conveyor belts 21 are driven by the rotating hub 22 to start running; this realizes the function that the plate can be automatically inspected through the conveyor belt 21. The conveyor belt 21 sends the plate from one end of the workbench 11. Through the drive of the rotating hub 22, the plate will be transported on the conveyor belt 21, and finally enter the detection area set under the gantry 37. Compared with the traditional method of relying on manual inspection one by one, it realizes an automated inspection process and saves labor costs.

[0034] Please refer to Figure 2 , Figure 3 and Figure 4 As shown, a support plate 13 is provided on the workbench 11, and multiple groups of fixing members 14 are connected to the bottom of the support plate 13. Each group of fixing members 14 is fixedly connected to the workbench 11 by screws, which ensures that the support plate 13 can maintain a stable and non-displaced state on the surface of the workbench 11, and the top of the support plate 13 is in contact with the conveyor belt 21; through this arrangement, the plate can be supported by the support plate 13 during the conveying process, preventing the plate from moving or tilting on the conveyor belt 21 due to external factors such as vibration, thereby affecting the detection results. The cooperation between the support plate 13 and the fixing members 14 ensures that the posture of the plate is stable during the conveying and detection process.

[0035] Please refer to Figure 2As shown, in order to classify defective products, a cylinder 15 is also provided on one side of the workbench 11, and a push plate 16 is fixed on the pneumatic rod of the cylinder 15; when the plate is defective, the cylinder 15 is started, and as the gas in the cylinder 15 drives, the pneumatic rod will extend outward, and at the same time drive the push plate 16 fixed thereon to move; at this time, the push plate 16 will touch the defective plate transported on the conveyor belt 21, and push it out of the main transport channel of the conveyor belt 21, and the push plate 16 pushes the defective plate to move to one side of the workbench 11, thereby realizing the classification and exclusion of the defective plate.

[0036] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
