Description

Technical Field

[0001] The utility model relates to the technical field of woodworking equipment, in particular to a device for identifying upper and lower side information of material selection. 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 surface condition 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, and cannot collect information on the lower surface of the wood at the same time; therefore, if it is necessary to collect information on both the upper and lower surfaces of the wood, it is necessary either to collect the wood and turn it over and make another trip, or to turn the wood over and enter another similar device to collect information on the other side. The process is cumbersome, time-consuming, and very inconvenient. Utility Model Content

[0033] 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.

[0034] like Figures 1 to 6 As shown, a device for identifying upper and lower side information of material selection includes a conveying mechanism. The feature of the device is that the information of the upper and lower sides of the material 0 can be collected after the material 0 is conveyed once on the conveying mechanism, which is very convenient and saves process and time. Specifically, a first image recognition component 1 is arranged above the conveying mechanism for collecting the upper side information of the material 0; the conveying mechanism is provided with a hollow position 501, and the width dimension of the hollow position 501 is greater than or equal to the width dimension of the material 0 to be measured; a second image recognition component 2 is arranged below the hollow position 501, and the material 0 moves forward relative to the hollow position 501 under the action of the conveying mechanism, and the second image recognition component 2 collects the lower side information of the material 0 through the hollow position 501. The width dimension of the hollow position 501 is generally set to be greater than the width dimension of the material 0 to be measured, so that the material 0 can be detected more comprehensively. In this embodiment, the material 0 refers to a short wooden board.

[0035] The conveying mechanism includes a first conveying body 3 and a second conveying body 4. A transition plate 5 is provided at the connection between the first conveying body 3 and the second conveying body 4, and a hollow position 501 is opened on the transition plate 5; the material 0 is conveyed from one side of the second conveying body 4 to the other side of the first conveying body 3. The setting of the transition plate 5 can reduce the gap between the first conveying body 3 and the second conveying body 4, which is helpful for the smooth conveying of the material 0 and avoids material jamming and material falling; in practice, a fixed plate will also be installed at the connection between the front and rear sides of the first conveying body 3 and the second conveying body 4, and the two ends of the transition plate 5 are connected to the fixed plate.

[0036] A frame 6 is provided next to the conveying mechanism, and a movable plate 7 is connected to the frame 6 in a lifting manner. The movable plate 7 is provided with a plurality of clamping components 8; the clamping components 8 are used to press the material 0 against the conveying surface of the conveying mechanism for smooth conveying, and the movable plate 7 can adjust the height according to actual conditions to adapt to materials 0 of different thicknesses. The movable plate 7 is connected to the frame 6 by sliding up and down on a guide rail, and a first driving mechanism 9 is provided on the frame 6, and the first driving mechanism 9 is connected to a first lifting screw 10, and a nut seat 11 is connected to the back of the movable plate 7, and the first lifting screw 10 is connected to the first screw nut in the nut seat 11. According to the principle of the screw module, the first driving mechanism 9 drives the first lifting screw 10 to rotate, which can control the lifting and lowering of the nut seat 11, that is, the lifting and lowering of the movable plate 7, to adapt to the pressing of materials 0 of different thicknesses.

[0037] like Figure 3 As shown, the clamping assembly 8 includes a telescopic cylinder 801, which can be an air cylinder or an oil cylinder. One end of the telescopic cylinder 801 is rotatably connected to the movable plate 7, and the other end of the telescopic cylinder 801 is rotatably connected to the middle part of the swing arm plate 802; one end of the swing arm plate 802 is rotatably connected to the movable plate 7, and the other end of the swing arm plate 802 is rotatably connected to a pressure wheel 803. When working, the pressure wheel 803 is pressed against the material 0, and the material 0 drives the pressure wheel 803 to rotate during transportation. From the above structure, it can be seen that when the rod body of the telescopic cylinder 801 is extended, it will drive the swing arm plate 802 to rotate downward, that is, the pressure wheel 803 is lowered; when the rod body of the telescopic cylinder 801 is retracted, it will drive the swing arm plate 802 to rotate upward, that is, the pressure wheel 803 is raised. The clamping assembly 8 is also used to adjust the pressure on materials 0 of different thicknesses. It can be understood that adjustment through the clamping assembly 8 is fine adjustment, and the method of adjusting the height of the movable plate 7 is coarse adjustment.

[0038] The first image recognition component 1 includes a fixed plate 101 and a second driving mechanism 102. In actual production, an external frame or a frame is also provided on the outside of the device. The two ends of the fixed plate 101 are fixed on the external frame or the frame, and the fixed plate 101 is stationary; the second driving mechanism 102 is connected to a second lifting screw rod 103, and a second screw nut 104 is provided on the fixed plate 101, and the second lifting screw rod 103 is connected to the second screw nut 104; therefore, according to the working principle of the screw rod module, it can be known that the second driving mechanism 102 drives the second lifting screw rod 103 to rotate, which will control the second driving mechanism 102 to rise and fall relative to the fixed plate 101; the lower end of the second lifting screw rod 103 is rotatably connected to the first bracket plate 105 through a bearing, so the rotation of the second lifting screw rod 103 will not drive the first bracket plate 105 to rotate; Figure 5 As shown, in order to further enhance stability, guide rods are provided on both sides of the second lifting screw rod 103, and linear bearings are provided at the corresponding positions of the fixed plate 101, and the guide rods are connected to the linear bearings; the upper ends of the guide rods are connected to the second driving mechanism 102, and the lower ends of the guide rods are connected to the first bracket plate 105; the setting of the guide rods and the linear bearings enhances the stability of the second driving mechanism 102 in lifting and lowering relative to the fixed plate 101, and also enhances the stability of the first bracket plate 105.

[0039] In this embodiment, the first driving mechanism 9 and the second driving mechanism 102 can be motors, directly connected to the first lifting screw rod 10 and the second lifting screw rod 103; they can also include components such as a reduction gearbox and a conveyor belt, as long as power can be input to drive the first lifting screw rod 10 and the second lifting screw rod 103 to achieve forward and reverse rotation.

[0040] The first support plate 105 is connected to a first image collector 106 , which collects information about the upper side of the material 0 . The height of the first image collector 106 is ultimately controlled by the second driving mechanism 102 .

[0041] A first light source 12 is arranged next to the first image collector 106. The first light source 12 is fixed on a light source horizontal plate 13. The light source horizontal plate 13 is connected to the lower end of a light source vertical plate 14. The upper end of the light source vertical plate 14 is connected to the second driving mechanism 102. The first light source 12 is used to illuminate the upper side of the material 0 to enhance the collection effect. The height of the first image collector 106 is also synchronously adjusted by the second driving mechanism 102.

[0042] The second image recognition component 2 includes a second image collector 201, which is located directly below the hollow position 501; the second image collector 201 is connected to the second bracket plate 202, and the second bracket plate 202 is connected to the lifting mechanism 203; the second image collector 201 is used to collect information on the bottom surface of the material 0, and the lifting mechanism 203 can be a height-adjustable component such as a screw module or a cylinder, which is not limited here, and can adjust the height of the second bracket plate 202. A second light source 15 is arranged next to the second image collector 201 to provide an illumination effect on the bottom surface of the material 0. Under the action of the conveying mechanism, the material 0 moves forward relative to the hollow position 501, so that the second image collector 201 can collect the bottom surface information of the entire material 0.

[0043] In this embodiment, the first image collector 106 and the second image collector 201 are both cameras.

[0044] The first conveying body 3 and the second conveying body 4 are both belt drive structures, that is, they include a driving shaft and a driven shaft, and the driving shaft and the driven shaft are connected by a conveyor belt; the material 0 is transported on the side of the conveyor belt. In this structure, the rotating shafts of the first conveying body 3 and the second conveying body 4 are set on the side close to the transition plate 5, and the rotating shafts of the two can be both without external power, or one of them has an external driving force and the other does not; the ends of the rotating shafts are coaxially connected with a second synchronous pulley 16, and the two second synchronous pulleys 16 are connected by a second synchronous belt 17, that is, the two rotating shafts are synchronously rotated by the second synchronous belt 17, and this synchronization helps the conveyor belts to move at the same speed, which is conducive to the smooth transition of the material 0.

[0045] In order to enhance the smoothness of the material 0 transition, the corresponding pressing wheel 803 is also synchronized. Figures 2 to 4 As shown, two adjacent pressing wheels 803 in the middle are coaxially connected with a flexible shaft 804; one of the two pressing wheels 803 is located above the first conveying body 3, and the other is located at the second conveying body 4; the connection method of the two pressing wheels 803 is that one end of the flexible shaft 804 is connected to the pressing wheel 803, and the other end of the flexible shaft 804 is connected to the first synchronous pulley 805; the two first synchronous pulleys 805 are connected by a first synchronous belt 806; Figure 4It can be seen that the flexible shaft 804 is supported by a frame near the first synchronous pulley 805, and the end of the flexible shaft 804 is rotatably connected to the frame through a bearing, and then the flexible shaft 804 will extend and connect to the first synchronous pulley 805; the purpose of the two pressing wheels 803 being controlled by the first synchronous pulley 805 and the first synchronous belt 806 is to keep the rotation speed of the two synchronized, which helps to make the material 0 transition smoothly. From the above description, it can be seen that the pressing wheel 803 can be adjusted in height by the telescopic cylinder 801, so the pressing wheel 803 is connected by the flexible shaft 804, 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 804 achieves the role of force transmission, and does not affect the micro-adjustment of the height of the pressing wheel 803 by the telescopic cylinder 801.

[0046] An encoder 807 is connected to one of the first synchronous pulleys 805. The mechanical shaft of the encoder 807 is connected to the flexible shaft 804. The movement of the material 0 drives the pressing wheel 803 to rotate, thereby driving the flexible shaft 804 to rotate. The encoder 807 recognizes the rotation of the flexible shaft 804 and converts it into a digital signal output, thereby knowing the length of the material 0.

[0047] The conveying mechanism is provided with a side leaning member, which includes a fixed seat 18, and the fixed seat 18 is connected to one end of a side plate 19. The other end of the side plate 19 is connected to a bearing 20. When the material 0 is conveyed, the side of the bearing 20 is rotatably connected to the material 0. The side leaning member helps to limit the material 0 to the bottom of the clamping assembly 8 for conveying.

[0048] 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.
