[0034] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] Please refer to Figures 1 to 4 , a preferred embodiment of the present utility model provides a wooden board sorting device, which mainly includes a feeding conveyor belt 10, a visual recognition device 20, a main sorting conveyor belt 30, a sub-sorting belt, a sorting mechanism, and an industrial control computer 50.

[0036] The feeding conveyor belt 10 is used to achieve feeding. The wooden boards enter through the feeding conveyor belt 10. The feeding conveyor belt 10 can feed multiple wooden boards to be sorted at the same time. The multiple wooden boards to be sorted are arranged horizontally on the feeding conveyor belt 10. Correspondingly, the feeding conveyor belt 10 should have a certain width to be able to stably place multiple horizontally arranged wooden boards. In an exemplary implementation mode of the present utility model, three wooden boards are taken as a group, and a group of wooden boards are arranged horizontally on the feeding conveyor belt 10 and enter together. By putting multiple horizontally arranged wooden boards at the same time, the feeding and conveying efficiency can be improved, thereby helping to improve the sorting efficiency. It can be understood that multiple groups of wooden boards can also be sequentially placed on the feeding conveyor belt 10.

[0037] The visual recognition device 20 is arranged beside the feed conveyor belt 10, and is used to visually recognize the wood boards to be sorted so as to classify the wood boards to be sorted. In this preferred embodiment, the visual recognition device 20 classifies the wood boards according to the color scale value. In this exemplary embodiment, the wood boards are mainly divided into four categories, namely A, B, C and defects. The A, B and C categories correspond to light, medium and dark colors respectively and have a certain range of color scale values. The color scale values ​​of the A, B and C categories are continuous, and for wood boards with a color scale value less than that of the A category or higher than that of the C category, they can be divided according to the defect category. It can be understood that in some other embodiments, wood grain and the like can also be used as classification parameters, and there can be multiple parameters used as classification parameters. In this exemplary embodiment, the feed conveyor belt 10 passes through the visual recognition device 20. The visual recognition device 20 has a box body, which has a certain light-shielding property so as to block the external light source, so as to reduce the interference caused by the change of the external light source on the recognition. A sensor (such as a proximity switch) and a light source are arranged inside the box body to detect whether the wooden board has entered. When the wooden board enters the box body of the visual recognition device 20, it is detected by the sensor. At this time, the visual recognition device 20 receives a signal and turns on the light source. Since there is only the light source in the box body of the visual recognition device 20, it can avoid the change of the external light source and affect the color level detection, thereby ensuring the monitoring accuracy. When the wooden board enters the box body of the visual recognition device 20, after turning on the light source, the camera device (such as a CCD camera) configured by the visual recognition device 20 takes pictures of the wooden boards fed in side by side for identification, and classifies the wooden boards according to the preset classification method. At this time, wooden boards at different positions are classified into one of the A, B, C or defective categories according to the color level value. The visual recognition device 20 is equipped with a touch display 21, which can display the control interface of the visual recognition device 20 and can perform parameter setting and other operations on the visual recognition device 20 through the touch display 21. At the same time, the classification results can be displayed through the touch display 21, such as the classification corresponding to the recognized wooden board.

[0038] The front end of the main sorting conveyor belt 30 is connected to the end of the feed conveyor belt 10, and is used to receive the identified wooden boards conveyed by the feed conveyor belt 10. The positions of the wooden boards identified by the visual recognition device 20 will not be disrupted, that is, they will still enter the main sorting conveyor belt 30 in the same arrangement as on the feed conveyor belt 10. At this time, the main sorting conveyor belt 30 should also have a certain width to be able to stably place multiple horizontally arranged wooden boards. In this preferred exemplary embodiment, the width and height of the main sorting conveyor belt 30 are consistent with those of the feed conveyor belt 10, and the extension direction is also consistent.

[0039] There are three sub-sorting belts, which are arranged beside the main sorting conveyor belt 30. In this exemplary embodiment, all the sub-sorting belts are located on one side of the main sorting conveyor belt 30. In this exemplary embodiment, the three sub-sorting belts are sequentially denoted as the first sub-sorting belt 61, the second sub-sorting belt 62, and the third sub-sorting belt 63 in the direction gradually away from the main sorting conveyor belt 30. Among them, during sorting, the wooden boards corresponding to category A will be transported to the first sub-sorting belt 61 for conveying, the wooden boards corresponding to category B will always be conveyed on the main sorting conveyor belt 30, the wooden boards corresponding to category C will be transported to the second sub-sorting belt 62 for conveying, and the wooden boards corresponding to the defective category will be transported to the third sub-sorting belt 63 for conveying. At this time, the four types of wooden boards are conveyed to the rear end by different sorting conveyor belts, so that the sorting of different types of wood can be realized. It can be understood that each sub-sorting belt can be an independent sorting belt and operate independently, or a sorting belt can be divided into multiple sub-sorting belts through longitudinal partitions. For example, in this exemplary embodiment, a sorting belt is partitioned into three sub-sorting belts by two longitudinally extending side plates 49. In this exemplary embodiment, the side plate 49 is fixedly connected to the bracket 65 fixedly arranged on the sorting belt.

[0040] The sorting mechanism is arranged beside the main sorting conveyor belt 30 to transport the classified wooden boards to a corresponding sub-sorting belt, so as to realize the sorting of the wooden boards by using different sub-sorting belts to convey the correspondingly classified wooden boards.

[0041] The industrial control computer 50, as a control system, is electrically connected to the vision recognition device 20 and the sorting mechanism respectively, and is used to receive the detection signal of the vision recognition device 20 to classify the wooden boards to be sorted, and control the sorting mechanism to transport the classified wooden boards to a corresponding sub-sorting belt.

[0042] The sorting mechanism includes a support frame 41, on which a plurality of sorting units 40 are arranged. The sorting units 40 are used to carry the wooden boards. The sorting unit 40 includes a support member 42 horizontally arranged on the support frame 41. The support member 42 is located directly above the main sorting conveyor belt 30. Exemplarily, the support member 42 is a horizontally arranged rod supported by a vertical rod. A horizontal linear module 43 for realizing horizontal movement is arranged on each support member 42. The horizontal linear module 43 can adopt one of the synchronous belt type, ball screw type, and linear motor type. Through the horizontal linear module 43, smooth and precise horizontal movement can be realized. The walking path of the horizontal linear module 43 covers the main sorting conveyor belt 30 and all sub-sorting belts. The horizontal linear module 43 has a horizontal movement module, on which an electric push rod 44 for realizing vertical telescoping is arranged. An adsorption mechanism 45 capable of adsorbing the wooden board is arranged at the end of the telescopic rod of the electric push rod 44. The horizontal linear module 43 and the electric push rod 44 are respectively electrically connected to the industrial control computer 50 and are controlled by the industrial control computer 50. During implementation, the horizontal linear module 43 can drive the electric push rod 44 and the adsorption mechanism 45 thereon to move horizontally above the main sorting conveyor belt 30 and directly above one of the wooden boards 70. Then, the electric push rod 44 is driven to extend its telescopic rod and drive the adsorption mechanism 45 downward until the adsorption mechanism 45 abuts against the wooden board 70. At this time, the adsorption mechanism 45 adsorbs the wooden board 70, so that when the telescopic rod of the electric push rod 44 retracts, the wooden board can move upward together with the adsorption mechanism 45; after the adsorption mechanism 45 adsorbs the wooden board 70, according to the classification recognized by the visual recognition device 20, the wooden board 70 is carried to the corresponding sub-sorting belt. At this time, the horizontal linear module 43 drives the electric push rod 44 and the adsorption mechanism 45 thereon to move horizontally above the corresponding sub-sorting belt. Then, the electric push rod 44 drives its telescopic rod to extend and drive the adsorption mechanism 45 downward to make the wooden board 70 approach the belt of the sub-sorting belt. Then, the adsorption mechanism 45 releases the adsorption of the wooden board, and the wooden board 70 falls onto the sub-sorting belt and is conveyed backward along with the sub-sorting belt. At this time, one sorting unit realizes the sorting of one wooden board 70. It can be understood that in this exemplary embodiment, since the Class B wooden boards are always conveyed by the main sorting conveyor belt 30, the wooden boards classified as Class B do not need to be sorted and conveyed through the sorting unit. That is, for a certain type of wooden board that is always conveyed by the main sorting conveyor belt 30, it does not need to be carried to the sub-sorting belt for sorting.

[0043] The extending directions of the respective sub-sorting belts are consistent with the extending direction of the main sorting conveyor belt 30. The wooden boards enter longitudinally and are longitudinally placed on the respective sub-sorting belts (if sorted), which can reduce the widths of the respective sub-sorting belts. Side plates 49 are arranged between the respective sub-sorting belts to ensure that when the sorted wooden boards are placed on the respective sub-sorting belts, they will not partially enter other sub-sorting belts.

[0044] The adsorption mechanism 45 includes a mounting rod 46 and a pneumatic suction cup 47. The mounting rod 46 is a straight square rod-shaped structure, and the extending direction of the mounting rod 46 is consistent with the extending direction of the sub-sorting belt. The pneumatic suction cup 47 is arranged at the bottom of the mounting rod 46 for adsorbing the wooden board. The wooden board can be adsorbed through the negative pressure effect of the pneumatic suction cup 47. During implementation, when a sorted wooden board needs to be transported to the corresponding sub-sorting belt, the horizontal linear module 43 drives the adsorption mechanism 45 to move to the position directly above the main sorting conveyor belt 30 corresponding to the wooden board. When the main sorting conveyor belt 30 conveys the wooden board to directly above the horizontal linear module 43, the electric push rod 44 drives the pneumatic suction cup 47 of the adsorption mechanism 45 downward to abut against the wooden board. At the same time, the pneumatic suction cup 47 generates negative pressure to adsorb the wooden board. The electric push rod 44 drives the pneumatic suction cup 47 of the adsorption mechanism 45 upward to leave the main sorting conveyor belt 30. Then, the horizontal linear module 43 drives the adsorption mechanism 45 to move to directly above the corresponding sub-sorting belt. The pneumatic suction cup 47 releases the negative pressure, and the wooden board falls onto the corresponding sub-sorting belt and is conveyed to the rear by the corresponding sub-sorting belt to achieve sorting. A buffer rod 410 is arranged between the pneumatic suction cup 47 and the mounting rod 46. The buffer rod 410 is a spring buffer rod, which has a buffering effect and can realize telescoping over a certain distance, avoiding damage to the wooden board when the pneumatic suction cup 47 abuts against the wooden board and impacts the wooden board, and can adapt to the vertical movement error of the pneumatic suction cup 47 to ensure abutment with the wooden board.

[0045] There are multiple pneumatic suction cups 47 at the bottom of the installation rod 46. The multiple pneumatic suction cups 47 are evenly arranged, and the arrangement direction is consistent with the extension direction of the sub-sorting belt. The multiple pneumatic suction cups 47 can achieve multi-point adsorption of the wooden board in the longitudinal direction to achieve stable adsorption. A horizontally arranged stop bar 64 is provided at the position of the sub-sorting belt corresponding to the sorting mechanism. The stop bar 64 is staggered from the pneumatic suction cup 47 in the horizontal direction. The stop bar 64 is fixedly arranged, such as fixedly arranged on the guardrail 48 on the side of the support frame 41 or arranged on the support 65 above the sub-sorting belt; in this exemplary embodiment, the stop bar 64 is fixedly arranged on the guardrail 48 on the side of the support frame 41 and is higher than the support 65 so that the wooden board can enter between the support 65 and the stop bar 64. By providing the stop bar 64, when the pneumatic suction cup 47 drives the wooden board to move and the wooden board is located below the stop bar 64, when the pneumatic suction cup 47 releases the adsorption of the wooden board, the wooden board may not fall naturally due to reasons such as the smoothness of the wooden board. At this time, the electric push rod 44 drives the pneumatic suction cup 47 upward, and the wooden board will contact the stop bar 64, then the wooden board can be knocked off to ensure the wooden board falls. There are multiple stop bars 64 corresponding to each adsorption mechanism 45. The multiple stop bars 64 are arranged and distributed along the extension direction of the sub-sorting belt to achieve multi-point simultaneous action on the wooden board and avoid the wooden board tilting and falling due to single-point action, which affects the accurate dropping of the wooden board onto the designated sub-sorting belt. A baffle 411 is provided at one end of the installation rod 46 away from the feeding conveyor belt 20. The baffle 411 is arranged downward and is slightly lower than the pneumatic suction cup 47. When a sorting unit 40 is used to carry the wooden board, the baffle 411 is lowered and the lower end of the baffle 411 is slightly lower than the top surface of the wooden board. At this time, the wooden board cannot pass through the baffle 411, ensuring that the adsorption mechanism can continue to adsorb the wooden board downward.

[0046] The number of sorting units is twice the number of sub-sorting belts, and each sub-sorting belt corresponds to two sorting units. By setting twice the number of sub-sorting belts of sorting units, multiple sorting units are used to sort a type of wooden board, avoiding the situation that the same type of wooden boards entering in the same batch are too many for a single sorting unit to sort, and ensuring the sorting efficiency and accuracy. In this exemplary embodiment, there are six sorting units, which are sequentially distributed in the same direction as the extension direction of the main sorting conveyor belt 30. Among them, the first and second sorting units are used to sort the wooden boards corresponding to type A, the third and fourth sorting units are used to sort the wooden boards corresponding to type C, and the fifth and sixth sorting units are used to sort the wooden boards corresponding to the defective type.

[0047] Both sides of the support frame 41 are located outside the sub-sorting belt to surround the sub-sorting belt from both sides, and guardrails 48 are provided on both sides of the support frame 41.

[0048] The main sorting conveyor belt 30 is provided with a proximity sensor 31 for detecting whether the wooden board is close to the sorting mechanism at the forward position of the sorting mechanism. The proximity sensor 31 is electrically connected to the industrial control computer 50. The proximity sensor 31 can detect the position where the wooden board enters the path of the main sorting conveyor belt 30 to obtain the path time of the wooden board. By transmitting the detection signal to the industrial control computer 50, the industrial control computer 50 controls the corresponding sorting unit to move to a certain position of the main sorting conveyor belt 30 at a certain time through the signal and controls the electric push rod 44 to move downward to realize the precise adsorption of the wooden board by the adsorption mechanism 45.

[0049] In some embodiments, it is possible that more wooden boards enter the feeding conveyor belt 10 together. For example, 5 wooden boards are arranged side by side in a form of being nested with each other on the side. After identification and classification, the 5 wooden boards need to be separated. The separation method is that the second and fourth wooden boards enter the main sorting conveyor belt 30 with a delay. At this time, a cross bar 11 is provided at the end position of the feeding conveyor belt 10. Two separating rods 12 are rotatably installed on the cross bar 11. The separating rods 12 are in a T shape and are connected to the cross bar 11 through a spring 13 (a tension spring in an exemplary embodiment) so that the separating rods 12 are tilted upward and higher than the conveying surface of the feeding conveyor belt 10. The two separating rods 12 respectively correspond to the positions of the second and fourth wooden boards. When the 5 wooden boards are transported to the end position of the feeding conveyor belt 10 together, since the two separating rods 12 respectively correspond to the second and fourth wooden boards, the first, third, and fifth wooden boards enter the main sorting conveyor belt 30 first. The second and fourth wooden boards gradually overcome the spring force to drive the separating rods 12 to rotate and move downward, and then enter the main sorting conveyor belt 30. After the second and fourth wooden boards enter the main sorting conveyor belt 30, the separating rods 12 are reset under the action of the spring 13 to realize subsequent separation operations. The T-shaped separating rods 12 can also be realized by a spring 13 that is a torsion spring to keep upward and reset after being pressed down by the wooden board. The spring 13 that is a torsion spring is sleeved on the horizontal part of the T-shaped separating rod 12, and both ends are fixedly connected to the cross bar 11.

[0050] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
