Description

Technical Field

[0001] The utility model relates to the technical field of woodworking equipment, in particular to a visual information recognition material selection machine. Background Art

[0002] In the process of processing and using woodworking materials, short boards and long boards are used according to needs. 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.

[0003] Currently, there are patents disclosed about the selection of wood materials, such as China Authorization Announcement No. CN211865880U, which discloses a small wood sorting device.

[0004] However, according to the specification and drawings of the patent document, the camera is fixedly located directly above the conveyor belt and can only take pictures vertically from top to bottom, that is, it can only collect information on the upper surface of the wood, but cannot collect images of the front, rear sides and lower surface of the wood, which has certain limitations. Based on this, the present application discloses a visual information recognition material selection machine to overcome the above defects. Utility Model Content

[0043] 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.

[0044] like Figures 1 to 12 As shown, a visual information recognition material selection machine includes a first transmission mechanism 1, a second transmission mechanism 2, and a third transmission mechanism 3 arranged according to the process flow; in this embodiment, the first transmission mechanism 1, the second transmission mechanism 2, and the third transmission mechanism 3 are all belt transmission devices, and the first transmission mechanism 1 is correspondingly provided with a front and rear side information recognition device; the connection between the first transmission mechanism 1 and the second transmission mechanism 2 is provided with an upper and lower side information recognition device; the third transmission mechanism 3 is correspondingly provided with a rotating material pushing device 13; the overall working principle of this visual information recognition material selection machine is to first collect information from the front and rear sides of the material 0, and then collect information from the upper and lower sides of the material 0, so as to know the surface condition of each piece of material 0; then the information will be transmitted to the background, and the background will output a signal to the rotating material pushing device 13 to work, so as to push out the qualified material 0 for material selection and classification. This material selection machine is mainly used in the selection of short wooden boards, because material 0 refers to short wooden boards.

[0045] Specifically, the front and rear side information recognition device includes two first image recognition components 4 arranged opposite to each other for collecting information on the front and rear sides of the material 0, wherein one first image recognition component 4 faces the feeding side of the first transmission mechanism 1, and the other first image recognition component 4 faces the discharging side of the first transmission mechanism 1; that is, the first image recognition component 4 facing the feeding side of the first transmission mechanism 1 is used to collect information on the front side of the material 0, and the first image recognition component 4 facing the discharging side of the first transmission mechanism 1 is used to collect information on the rear side of the material 0; the collected material 0 will be input into the second transmission mechanism 2 for transmission, so as to facilitate the upper and lower side information recognition devices to collect images.

[0046] The image recognition component includes a first support 401, which is connected to the first conveying mechanism. The first support 401 is rotatably connected to a first fixing member 402, and an image collector 403 is arranged on the first fixing member 402. The image collector 403 is fixed to the first fixing member 402 by screws. The rotatable connection of the first support 401 facilitates adjustment of the illumination angle of the image collector 403, and facilitates adjustment of the optimal angle for collecting the side information of the material 0. In this embodiment, the image collector 403 is a camera.

[0047] A light source illumination component 5 is arranged next to the first image recognition component 4; the light source illumination component 5 includes a second support 501, the second support 501 is connected to the first transmission mechanism 1, a second fixing member 502 is rotatably connected to the second support 501, and a light source 503 is arranged on the second fixing member 502; the structure and connection method of the second support 501 and the second fixing member 502 are consistent with the structure and connection method of the first support 401 and the first fixing member 402, which will be further described below. The light source illumination component 5 is to enhance the lighting effect on the material 0, which is conducive to collecting clear pictures.

[0048] like Figure 5 The specific structure is described by taking the first support 401 and the first fixing member 402 as an example: a first connecting hole 4011 is provided on the first support 401 / the second support 501, and a second connecting hole 4021 is provided on the first fixing member 402 / the second fixing member 502, and the first connecting hole 4011 and the second connecting hole 4021 are used correspondingly; a plurality of first fixing holes 4012 are also provided on the first support 401 / the second support 501, and the plurality of first fixing holes 4012 are dispersed and surrounded outside the first connecting hole 4011; an arc-shaped slot 4022 is provided on the first fixing member 402 / the second fixing member 502, and an arc trajectory formed by a center line connecting the plurality of first fixing holes 4012 matches the curvature of the arc-shaped slot 4022.

[0049] The purpose of the above matching is that, during installation, a bolt is passed through the first connecting hole 4011 and the second connecting hole 4021, 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 401 and the first fixing member 402 are initially fixed. At this time, the first fixing member 402 can rotate with the first connecting hole 4011 (the second connecting hole 4021) as the center of the circle; when adjusting the angle, the first fixing member 402 rotates within a certain range, and the arc-shaped slots 4022 can overlap with the first fixing hole 4012. Therefore, after the rotation angle of the first fixing member 402 is adjusted (that is, the angle of the image collector 403), another bolt is inserted from the arc-shaped slot 4022 and passed through the corresponding first fixing hole 4012, and then the nut is screwed into the tail of the bolt and tightened. Then, the nuts on the bolts passing through the first connecting hole 4011 and the second connecting hole 4021 are tightened, and the first fixing member 402 can be fixed 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 lighting component 5 , which will not be described in detail herein.

[0050] A transition plate 6 is provided at the connection between the first transmission mechanism 1 and the second transmission mechanism 2. The provision of the transition plate 6 can reduce the gap between the first transmission mechanism 1 and the second transmission mechanism 2, which is helpful for the smooth transportation of the material 0 and avoids the occurrence of material jamming and material dropping. In practice, a fixed plate will also be installed at the connection between the front and rear sides of the first transmission mechanism 1 and the second transmission mechanism 2, and the two ends of the transition plate 5 are connected to the fixed plate. A hollow position 601 is provided on the transition plate 6. The upper and lower side information recognition device includes a second image recognition component 7 located above the transition plate 6 and a third image recognition component 8 located below the transition plate 6. The second image recognition component 7 and the third image recognition component 8 both include an image collector, that is, a camera. The second image recognition component 7 directly irradiates downward to collect information on the upper surface of the material 0. The width of the hollow position 601 is wider than the width of the material 0. Therefore, when the material 0 passes above the hollow position 601, the third image recognition component 8 collects the lower side information of the material 0 through the hollow position 601, so that the material 0 can be more comprehensively detected.

[0051] A frame 9 is arranged next to the connection between the first transmission mechanism 1 and the second transmission mechanism 2, and a movable plate 10 is connected to the frame 9 in a liftable manner, and the movable plate 10 is provided with a plurality of clamping assemblies 11; the movable plate 10 is provided with a slide rail, and the frame 9 is connected to the movable plate 10 through the slide rail; in the present embodiment, a screw module structure is adopted to control the lifting and lowering of the movable plate 10 on the frame 9; the clamping assembly 11 comprises a telescopic cylinder 1101, one end of the telescopic cylinder 1101 is rotatably connected to the movable plate 10, and the other end of the telescopic cylinder 1101 is rotatably connected to the middle part of the swing arm plate 1102; one end of the swing arm plate 1102 is rotatably connected to the movable plate 10, and the other end of the swing arm plate 1102 is rotatably connected to the pressure wheel 1103; the pressure wheel 1103 is located above the conveying surface of the first transmission mechanism 1 and the second transmission mechanism 2.

[0052] In this embodiment, the telescopic cylinder 801 is a pneumatic cylinder. When working, the pressure wheel 1103 is pressed against the material 0, and the material 0 drives the pressure wheel 1103 to rotate during transportation. From the above structure, it can be seen that when the rod of the telescopic cylinder 1101 is extended, it will drive the swing arm plate 1102 to rotate downward, that is, the pressure wheel 1103 is lowered; when the rod of the telescopic cylinder 1101 is retracted, it will drive the swing arm plate 1102 to rotate upward, that is, the pressure wheel 1103 is raised. The clamping assembly 11 is also used to adjust the pressure on materials 0 of different thicknesses. It can be understood that adjustment through the clamping assembly 11 is fine adjustment, and the method of adjusting the height of the movable plate 10 is coarse adjustment.

[0053] The two adjacent pressing wheels 1103 in the middle are coaxially connected with a flexible shaft 1104; one of the two pressing wheels 1103 is located above the conveying surface of the first transmission mechanism 1, and the other pressing wheel 1103 is located above the conveying surface of the second transmission mechanism 2; one end of the flexible shaft 1104 is connected to the pressing wheel 1103, and the other end of the flexible shaft 1104 is connected to a synchronous pulley 1105; the two synchronous pulleys 1105 are connected by a synchronous belt 1106, and this synchronous structure makes the rotation speed of the two pressing wheels 1103 the same, in order to enhance the smoothness of the transition of the material 0 between the first transmission mechanism 1 and the second transmission mechanism 2;

[0054] from Figure 8 as well as Fig. 9It can be seen that the flexible shaft 1104 is supported by a frame near the synchronous pulley 1105, and the end of the flexible shaft 1104 is rotatably connected to the frame through a bearing, and then the flexible shaft 1104 will extend and connect to the synchronous pulley 1105; the purpose of the two pressing wheels 1103 being controlled by the synchronous pulley 1105 and the synchronous belt 1106 is to keep the rotation speed of the two synchronized, which helps the material 0 to transition smoothly. From the above description, it can be seen that the pressing wheel 1103 can be adjusted in height by the telescopic cylinder 1101, so the pressing wheel 1103 is connected by the flexible shaft 1104, which is an elastic hose, or a soft steel tube with a core wire in the middle and several layers of steel wires wound alternately on the outside. Here, the flexible shaft 1104 achieves the role of force transmission, and does not affect the micro-adjustment of the height of the pressing wheel 1103 by the telescopic cylinder 1101.

[0055] An encoder 1107 is connected to one of the synchronous pulleys 1105; the mechanical shaft of the encoder 1107 is connected to the flexible shaft 1104. The movement of the material 0 drives the pressing wheel 1103 to rotate, thereby driving the flexible shaft 1104 to rotate. The encoder 1107 recognizes the rotation of the flexible shaft 1104 and converts it into a digital signal output, thereby knowing the length of the material 0.

[0056] like Figure 6 As shown, the first transmission mechanism 1 is provided with a side leaning member 12 at the material feeding position, and the side leaning member 12 includes a fixed seat 1201, and the fixed seat 1201 is connected to one end of a side plate 1202, and the other end of the side plate 1202 is connected to a bearing 1203, and the bearing 1203 is located on the side of the material 0; when the material 0 is conveyed, the side of the bearing 1203 is rotatably connected with the material 0, and the side leaning member 12 helps to limit the material 0 to be conveyed below the clamping assembly 11.

[0057] The rotating pushing device 13 is arranged along the conveying direction of the third transmission mechanism 3; the material 0 that has passed the above-mentioned detection will be input into the third transmission mechanism 3, and the rotating pushing device 13 is used to kick out the material 0 that meets the conditions laterally. Specifically, the rotating pushing device 13 includes a mounting plate 1301, and the mounting plate 1301 is fixed to the third transmission mechanism 3 with mounting bolts, and the mounting plate 1301 is provided with a first cylinder 1302 and a second cylinder 1303, and the first cylinder 1302 and the second cylinder 1303 are staggered in sequence; the piston rods of the first cylinder 1302 and the second cylinder 1303 are connected with a pushing head 1304, and the pushing head 1304 is in contact with the material 0; wherein the pushing head 1304 is located above the conveying surface of the third transmission mechanism 3, and the first cylinder 1302 and the second cylinder 1303 The extension and retraction direction of the piston rod is perpendicular to the conveying direction of the third transmission mechanism 3; that is, in this embodiment, there are multiple rotating pushing devices 13. When the background transmits a signal to one of the rotating pushing devices 13 for pushing, the piston rods of the first cylinder 1302 and the second cylinder 1303 of the rotating pushing device 13 are not pushed out at the same time. One of the cylinders can be actuated, and when the background transmits another signal to the rotating pushing device 13, the other cylinder will be actuated. This dual-cylinder setting can improve the pushing speed of the entire rotating pushing device 13 as a whole. This is because when the number of materials 0 is large and flows quickly, the piston rod of one of the cylinders may be extended and the subsequent piece of material 0 will pass by before it is reset. Therefore, this setting can meet the needs of rapid material selection, avoid fatigue of a single cylinder, and extend its service life.

[0058] The third transmission mechanism 3 is also connected to a front baffle support frame 14 by bolts, and the front baffle support frame 14 is connected to a front baffle plate 15, which is located on the side opposite to the rotating pushing device 13; a material drop gap 16 is reserved between the front baffle plate 15 and the third transmission mechanism 3, and a collecting frame is placed below the material drop gap 16, that is, the material 0 pushed out by the rotating pushing device 13 hits the front baffle plate 15, and will fall along the front baffle plate 15 from the material drop gap 16 to the collecting frame for collection; the front baffle plate 15 can be made of plastic products to reduce the damage to the material 0 during the impact and also reduce the impact noise.

[0059] 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. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
