DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] In the drawings, the same reference numerals all refer to the same components.

[0019] like Figure 1-4As shown, the present invention provides a wooden board processing system and method, including a screening machine 1, a splicing machine 2, a connecting machine 3, a cold press machine 4, a first hot press machine 5, a first sawing machine 6, a first sanding machine 7, a drying room 8, a second sanding machine 9, a second hot press machine 10 and a second sawing machine 11, the screening machine 1, the splicing machine 2, the connecting machine 3, the cold press machine 4, the first hot press machine 5, the first sawing machine 6, the first sanding machine 7, the drying room 8, the second sanding machine 9, the second hot press machine 10 and the second sawing machine 11 are arranged in sequence, and a conveyor for transporting materials is provided between each device. The screening machine 1 includes a warehouse body 101, a spotlight 102, a camera 103, a light sensor 104, a control box 105 and two belt conveyor components 106. The warehouse body 101 is arranged on the ground. The two belt conveyor components 106 are arranged horizontally and spaced apart, and a part of both is located in the warehouse body 101. The spotlight 102 is arranged above the warehouse body 101, and its end faces the space between the two belt conveyor components 106. The camera 103 and the light sensor 104 are arranged above the warehouse body 101, and the control box 105 is arranged on the warehouse body 101.

[0020] In this embodiment, when the veneer to be inspected is transported by the belt conveyor assembly 106 through the gap between the two belt assemblies 106, the light of the spotlight 102 above the warehouse body 101 irradiates the veneer downward, and the light sensor 104 below the warehouse body 101 detects the light penetrating the veneer, and at the same time, the camera 103 takes a picture of the veneer; The light sensor 104 detects the brightness of the light penetrating the veneer material, and inputs the brightness data into the computer built in the control box 105 for comparison with the preset brightness data. If the brightness is greater than the preset brightness data, the veneer material is unqualified, and if the brightness is less than the preset brightness data, the veneer material is qualified; The camera 103 inputs the photographed veneer material into the computer built in the control box 105 for processing, and after processing, the computer determines whether the veneer material is qualified; If one of the detections of the camera 103 or the light sensor 104 fails, the veneer material fails to meet the standards; The camera 103 is a 2K color line scan camera, and the model of the light sensor 104 is BX-H798.

[0021] Furthermore, the unloading end of the belt conveyor assembly 106 is also provided with a rejection assembly 12, and the rejection assembly 12 includes two cylinders 1201 and an arc-shaped baffle 1202. The baffle 1202 is arranged above the unloading end of the belt conveyor assembly 106, and its inner arc surface faces the belt conveyor assembly 106. The two cylinders 1201 are respectively arranged on the brackets of the two side plates of the belt conveyor assembly 106, and the piston rods of the two are vertically upward and connected to the baffle 1202.

[0022] In this embodiment, if the veneer material is unqualified, the control box 105 controls the two cylinders 1201 in the rejection assembly 12 to drive the arc-shaped baffle 1202 to move downward, and the veneer material contacts the inner arc surface of the baffle 1202 and moves downward along the arc surface until it leaves the belt conveyor assembly 106. If the veneer material is qualified, the baffle 1202 maintains its original position; A recovery unit for unqualified veneer is provided below the belt conveyor assembly 106 .

[0023] like Figure 4-12 As shown, the present invention provides a wooden board processing system and method, comprising the following steps: S1, screening the veneer materials and removing incomplete veneer materials; S2, splicing the screened veneers into leathers of appropriate length; S3, stacking the leather together and applying pressure to obtain a wooden board; S4, performing rough surface treatment on the wood board to obtain a board blank; S5, drying the sheet blank, and then performing surface finishing to obtain a semi-finished sheet; S6, performing veneer processing on the semi-finished board to obtain a board; S7, classifying the boards to obtain finished boards of different grades.

[0024] Furthermore, S1 includes the following sub-steps: S11, sending the veneer material to be screened to the screening machine 1 for testing through the transmission mechanism; S12, if the veneer material fails the inspection, it is removed from the conveying mechanism; if the veneer material passes the inspection, it is sent to splicing through the conveying mechanism.

[0025] Furthermore, S11 includes the following sub-steps: S111, the veneer material passes through the gap between the two belt conveyor assemblies 106, and the strong light emitted by the spotlight 102 irradiates the surface of the veneer material; S112, strong light can pass through the holes in the veneer and penetrate the deeper holes on the surface of the veneer; S113, the light sensor 104 detects the light intensity under the veneer. If the light exceeds the built-in standard value, it is determined that the veneer has defects. At the same time, the camera 103 takes a photo of the veneer and processes and analyzes the photo to determine whether the veneer has defects.

[0026] In this embodiment, the spotlight 102 irradiates the veneer downward. If there are cracks or deep holes on the veneer, the light of the spotlight 102 will pass through the veneer, so that the light sensor 104 under the veneer receives more light, which in turn increases the reading of the light sensor 104. When the reading of the light sensor 104 is greater than the preset value, it can be determined that the veneer is unqualified. At the same time, the camera 103 will also take a picture of the veneer material below, and determine whether the veneer material is qualified through computer algorithm processing; If one of the detections of the camera 103 or the light sensor 104 fails, the veneer material is unqualified.

[0027] Furthermore, S2 includes the following sub-steps: S21, sending the veneer material to the splicing machine 2 through the conveying mechanism for splicing, and splicing two or more pieces of veneer material together through the splicing machine 2; S22, the spliced ​​veneer material is sent to the wire joining machine 3 through the conveying mechanism, and the wire joining machine 3 lays wire on the surface of the spliced ​​veneer material to obtain a leather of appropriate length.

[0028] Furthermore, S3 includes the following sub-steps: S31, stacking a plurality of leathers after gluing them on a cold press machine 4 for cold pressing to obtain a semi-finished template; S32, primary repair of surface defects on semi-finished wood boards; S33, a plurality of semi-finished wood boards that have completed the first-level repair are coated with glue and stacked on the first hot press 5 for hot pressing to obtain wood boards.

[0029] Furthermore, S4 includes the following sub-steps: S41, the wood board is sent to the first edge sawing machine 6 through the conveying mechanism for primary edge sawing; S42, the template after the first-level sawing is sent to the first sanding machine 7 through the conveying mechanism for first-level sanding; S43, performing secondary modification on the wooden board that has completed the primary sanding to obtain a board blank.

[0030] Furthermore, S5 includes the following sub-steps: S51, the sheet blank is sent to a drying place for drying through a conveying mechanism; S52, the dried plate blank is sent to the second sanding machine 9 through the conveying mechanism for secondary sanding and fine inspection to obtain a semi-finished plate.

[0031] Furthermore, S6 includes the following sub-steps: S61, the panels are placed on the front and back sides of the semi-finished board after gluing; S62, the semi-finished plate with the panel attached is then sent to the second hot press machine 10 through a conveying mechanism for hot pressing; S63, the semi-finished plate formed by hot pressing is then sent to the second edge sawing machine 11 through a conveying mechanism for edge sawing, and finally the edge is polished to obtain a plate.

[0032] The present invention relates to a wooden board processing system and method, which detects the transmittance of light emitted by a spotlight passing through veneer through a light sensor and a camera of a screening component, thereby judging whether the veneer is qualified. Unqualified veneer is removed by a removal component. The above scheme improves the accuracy and efficiency of veneer screening and detection, and reduces the labor intensity of workers.
