However, if long boards are processed as a whole, longer logs are needed, and the cost of raw materials used is relatively high. Short boards can be easily obtained because of their low requirements for raw material length. Therefore, from the perspective of raw material cost and processing convenience, if long boards are needed, short boards with smooth and flawless surfaces will be selected and bonded into long boards; when selecting short boards, the grades of the boards should be identified and divided so as to be sorted out and processed as needed; for example, if the entire short board meets the quality requirements, it can be directly screened out. If only one section (the first section or the last section) of the short board meets the quality requirements, the short board should be cut off, and the section that meets the quality should be selected and retained, and the other section should be discarded. Therefore, it is necessary to identify the information status of the front and back sides of the short board.

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.

[0032] like Figures 1 to 6 As shown, a device for identifying the front and rear side information of material selection comprises a conveying mechanism 1, on which an image recognition component 2 is arranged; wherein the image recognition component 2 comprises a first support 201, the first support 201 is connected to the conveying mechanism 1, a first fixing member 202 is connected to the first support 201, an image collector 203 is arranged on the first fixing member 202, and the image collector 203 is fixed to the first fixing member 202 by screwing; the first support 201 raises the first fixing member 202 so that the image collector 203 maintains a certain height from the conveying surface of the conveying mechanism 1, so that the image collector 203 can shoot and collect surface images of the material 8 conveyed from the conveying mechanism 1 downward; the first fixing member 202 can be rotatably connected to the first support 201 to adjust the shooting angle of the image collector 203 to the material 8 on the conveying mechanism 1, specifically, the image collector 203 shoots the front and back of the material 8 from the upper side. In this embodiment, the image collector 203 is a camera; the material 8 refers to a short wooden board.

[0033] The transmission mechanism 1 is provided with a light source illumination component 3; the light source illumination component 3 includes a second support 301, the second support 301 is connected to the transmission mechanism 1, a second fixing member 302 is rotatably connected to the second support 301, and a light source 303 is provided on the second fixing member 302. The structure and connection method of the second support 301 and the second fixing member 302 are similar to the structure and connection method of the first support 201 and the first fixing member 202, or in other words, the two sets of supports and fixing members are the same, and are respectively used to support and fix the image collector 203 and the light source illumination component 3. Therefore, the following focuses on only one set, and the first support 201 and the first fixing member 202 are used for description.

[0034] like Figure 5 As shown ( Figure 5The first support 201 and the first fixing member 202 are used for the description. A first connecting hole 2011 is provided on the first support 201 / the second support 301, and a second connecting hole 2021 is provided on the first fixing member 202 / the second fixing member 302. The first connecting hole 2011 and the second connecting hole 2021 are used correspondingly. During installation, a bolt is passed through the first connecting hole 2011 and the second connecting hole 2021, and then a nut is screwed into the tail of the bolt. At this time, the nut is not screwed tightly, so that the first support 201 and the first fixing member 202 are initially fixed. At this time, the first fixing member 202 can rotate with the first connecting hole 2011 (the second connecting hole 2021) as the center of the circle. A plurality of first fixing holes 2012 are also provided on the first support 201 / the second support 301, and the plurality of first fixing holes 2012 are dispersed and surrounded by the first fixing hole 2011. A connecting hole 2011; an arc-shaped slot 2022 is provided on the first fixing member 202 / the second fixing member 302, and the arc trajectory formed by the center line connecting the plurality of first fixing holes 2012 matches the curvature of the arc-shaped slot 2022. The purpose of the above matching is that the first fixing member 202 rotates within a certain range, and the arc-shaped slot 2022 can overlap with the first fixing hole 2012. Therefore, after adjusting the rotation angle of the first fixing member 202 (that is, the angle of the image collector 203), a bolt is inserted from the arc-shaped slot 2022 and passes through the corresponding first fixing hole 2012, and then a nut is screwed into the tail of the bolt and tightened. Then, the nut on the bolt passing through the first connecting hole 2011 and the second connecting hole 2021 is tightened to fix the first fixing member 202 on the first support 201. The second fixing member 302 is adjusted and fixed in the same manner as the second support 301 , and is used to adjust the tilt angle of the light source illumination component 3 , which will not be described in detail herein.

[0035] The image recognition component 2 and the light source illumination component 3 are arranged in pairs; they are divided according to the conveying direction of the material 8, with the image recognition component 2 and the light source illumination component 3 on the side close to the incoming direction of the material 8 as one group, and the image recognition component 2 and the light source illumination component 3 on the side close to the outgoing direction of the material 8 as another group. The image recognition components 2 and the light source illumination components 3 of the two groups are arranged symmetrically, and the shooting and irradiation angles of the material 8 are relative. Taking this embodiment as an example, the image recognition component 2 and the light source illumination component 3 are a pair, and the shooting and irradiation angles of the material 8 mentioned above are relative, which means that, combined with Figure 1 as well as Figure 2It can be seen that the material 8 is input from the right side of the conveying mechanism 1 and output from the left side. The image recognition component 2 and the light source lighting component 3 on the left are facing the feeding side, so as to illuminate the side in front of the material 8 (mainly the front end face of the material 8) for photographing and collecting. The image recognition component 2 and the light source lighting component 3 on the right are facing the discharging side, so as to illuminate the side behind the material 8 (mainly the rear end face of the material 8) for photographing and collecting. Moreover, looking at each group of image recognition components 2 and light source lighting components 3, the light source 303 is located on the inner side of the image collector 203 (with the center between the two groups of image recognition components 2 and light source lighting components 3 as a comparison). The purpose is to enhance the lighting effect on the material 8 and help to clearly collect the side image information of the material 8. In addition, the light source 303 is still higher than the image collector 203, so as not to block the image collector 203.

[0036] A mounting frame 4 is provided on the conveying mechanism 1, a longitudinal groove 2013 is provided on the first support 201 / the second support 301, and a mounting hole is provided on the mounting frame 4. The mounting hole is used corresponding to the longitudinal groove 2013. The first support 201 / the second support 301 can be fixed by connecting a screw through the longitudinal groove 2013 to the mounting hole; the longitudinal groove 2013 is helpful to adjust the height of the first support 201 / the second support 301.

[0037] Combination Figure 4 as well as Figure 6 It can be seen that a support plate 5 is arranged on the conveying mechanism 1, and a first adjusting block 501 is protrudingly arranged on the support plate 5; an elongated avoidance position 402 is arranged on the mounting frame 4, and during assembly, the mounting frame 4 can move relative to the support plate 5, and this movement is along the length direction of the support plate 5, and the first adjusting block 501 protrudes outward from the elongated avoidance position 402; a second adjusting block 403 is arranged on the mounting frame 4, and the second adjusting block 403 is connected with a bolt 404, and the bolt 404 is movably connected to the first adjusting block 501, and a through hole for the bolt 404 to pass through is opened on the first adjusting block 501, one end of the bolt 404 is fixedly connected to the second adjusting block 403, and the other end of the bolt 404 passes through the through hole on the first adjusting block 501, and this method enables the mounting frame 4 to move left and right relative to the support plate 5, thereby adjusting the left and right positions of the image recognition component 2 and the light source lighting component 3; the bolt 404 is connected with a nut 405, and after adjusting the position, the nut 405 can be tightened.

[0038] Each group of image recognition components 2 and light source illumination components 3 is correspondingly provided with a hood 6, and the hood 6 is connected to the transmission mechanism 1 by screws, and each group of image recognition components 2 and light source illumination components 3 is located within the horizontal projection area of ​​the corresponding hood 6, that is, when viewed from a top view, the hood 6 completely blocks the image recognition components 2 and light source illumination components 3, thereby achieving the purpose of protecting the image recognition components 2 and light source illumination components 3, and also reducing the dust from falling directly onto the image recognition components 2 and light source illumination components 3.

[0039] A baffle plate 7 is provided on the conveying surface of the conveying mechanism 1. The baffle plate 7 is connected to the frame of the conveying mechanism 1. The length direction of the baffle plate 7 is consistent with the moving direction of the conveyor belt on the conveying mechanism 1, and the bottom of the baffle plate 7 is not connected to the conveyor belt. Therefore, the baffle plate 7 can have a certain limiting effect on the material 8 and will not affect the conveyor belt. Figure 1 It can be seen that the feeding position of the baffle plate 7 (the right side of the baffle plate 7 in the drawing) is arranged to be opened outward, which can facilitate the material 8 to smoothly enter the area surrounded by the baffle plate 7.

[0040] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
