DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0050] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the invention is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0051] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0052] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0053] Please refer to Figures 1 to 3 The embodiment of the present invention provides an object detection and identification device 100, which is used to identify and classify the external dimensions of an object to be detected 101. It can be used for product inspection or classification in industrial production, and can also be used for item classification in daily life, such as the waste recycling industry. In this embodiment, the object to be detected 101 includes but is not limited to plastic boxes, plastic bottles, wooden blocks and other objects. The object detection and identification device 100 includes a box body 110, a carrier body 120 arranged in the box body 110, a first driving member 141 and an identification component 130. The first driving member 141 is connected to the carrier body 120 in a transmission manner. The carrier body 120 is provided with a receiving portion, and the receiving portion is used to install the object to be detected 101; the box body 110 is provided with a first storage cavity 10 and a second storage cavity 30 that are independent of each other, and the identification component 130 is located at the periphery of the carrier body 120. The identification component 130 is used to detect the external dimensions of the object to be detected 101. If the shape parameter is within the preset parameter range, that is, the object to be tested 101 meets the preset requirements, the first driving member 141 drives the carrier 120 to rotate along the first direction, so that the object to be tested 101 in the accommodating portion is turned over to the first storage cavity 10; if the shape parameter is outside the preset parameter range, that is, the object to be tested 101 does not meet the preset requirements, the first driving member 141 drives the carrier 120 to rotate along the second direction, so that the object to be tested 101 in the accommodating portion is turned over to the second storage cavity 30. In this way, the classification of the object to be tested 101 can be achieved by identifying the shape of the object to be tested 101, which has the advantages of simple structure, convenient operation and low manufacturing cost.

[0054] Please refer to Figure 4 and Figure 5 , the accommodating portion is a groove 123 provided on the carrier 120, and a delivery port 111 is provided on the box 110, and the delivery port 111 is connected to the groove 123. Optionally, in this embodiment, the object to be tested 101 is described by taking a bottle such as a mineral water bottle as an example, the carrier 120 is a hollow cylinder, one end of which has an opening 121, and the other end is provided with a bottom cover 122, the outer peripheral surface of the hollow cylinder is provided with a groove 123, the opening 121 is connected to the delivery port 111 of the box 110, and the bottom cover 122 is connected to the first driving member 141. Optionally, a transition connector 125 is provided between the bottom cover 122 and the first driving member 141, that is, the first driving member 141 is connected to the transition connector 125, and the transition connector 125 is connected to the bottom cover 122, so that it is convenient to replace the carrier 120 and the first driving member 141. The length and width of the groove 123 are designed according to the target object and are sufficient to accommodate the target object.

[0055] Further, the identification component 130 includes a plurality of detection heads arranged at intervals, and the plurality of detection heads are distributed along the groove 123 of the carrier 120, and are used to detect the shape parameters of the object 101 to be detected, and the shape parameters include length, width and / or height, that is, according to different classification standards, only the length parameter can be detected, or only the width parameter can be detected, or only the height parameter can be detected, or at least two parameters among the length, width and height can be detected, which are not specifically limited here. The plurality of detection heads are arranged on one side of the notch of the groove 123 and are distributed along the axis of the groove 123. In this embodiment, a mounting plate 128 is connected to one side of the carrier 120 where the groove 123 is opened, and the detection head is arranged on the side of the mounting plate 128 facing the groove 123, and there is a certain interval between the mounting plate 128 and the carrier 120 to ensure that the object 101 to be detected does not interfere with or collide with the mounting plate 128 and the detection head on the mounting plate 128 after entering the groove 123. Optionally, a slide groove (not shown) is provided on the mounting plate 128, and the detection head can be slidably mounted on the mounting plate 128. For example, the detection head can slide along the slide groove to a suitable position, and then the detection head position can be fixed by screw fastening or other means. The slidable installation of the detection head facilitates the adjustment of the installation position of the detection head, which is conducive to adjusting the distance between adjacent detection heads, and the arrangement is more flexible, so as to be suitable for the detection and identification of objects to be tested 101 of different shapes, and the application scenarios are flexible and the application range is wider. Further, the detection head can be fixed on a support plate (not shown), and the support plate can move along the slide groove of the mounting plate 128. When the support plate moves to a determined installation position, it is fixed by screws or bolts to realize the detachable connection of the detection head. In addition, the support plate can be provided with a height adjustment member, such as a stud or other adjustable connecting element, to realize the adjustment of the installation height of the detection head, that is, to realize the distance adjustment between the detection head and the bottom of the groove 123, so as to adapt to the identification of objects to be tested 101 of different heights. In this way, the installation of the detection head can realize both the distance adjustment along the axial direction of the mounting carrier 120 and the adjustment along the radial direction of the mounting carrier 120, which has a wide application range and is more flexible in installation and use.

[0056] It is easy to understand that in other optional embodiments, the mounting plate 128 may also be omitted, and the detection head may be directly mounted on the inner wall of the box 110 , including but not limited to the top wall or the side wall, as long as it ensures that the object 101 to be detected in the groove 123 can be detected.

[0057] The distance between two detection heads (such as the first and the Nth) is the first reference distance, and the distance between the other two detection heads (such as the first and the Mth) is the second reference distance, and the first reference distance is less than the second reference distance; there is no object 101 to be detected in the groove 123, and the detection head detection is empty, that is, all detection heads have not detected obstacles; there is an object 101 to be detected in the groove 123, and the detection head can detect obstacles. Since the detection heads are arranged at intervals, the maximum distance between the detection heads that detect obstacles is used to determine the actual length of the object 101 to be detected. If the actual length of the object 101 to be detected is greater than or equal to the first reference distance, and less than or equal to the second reference distance, it indicates that the object 101 to be detected is within the target object range, and the first driving member 141 is used to flip the object 101 to be detected to the first storage cavity 10 of the box 110; if the actual length is less than the first reference distance, or greater than the second reference distance, it indicates that the object 101 to be detected is not within the target object range, and the first driving member 141 is used to flip the object 101 to be detected to the second storage cavity 30 of the box 110.

[0058] Optionally, an indicator light (not shown) is provided on the detection head. When the detection head detects the object 101 to be detected, the indicator light is on; when the detection head does not detect the object 101 to be detected, the indicator light is off. The indicator light is used to indicate whether the detection head detects an obstacle, thereby improving the user experience.

[0059] Please refer to Figure 6 and Figure 7Furthermore, a transition tube 115 is provided at the delivery port 111 of the box body 110, and the carrier 120 is sleeved with the transition tube 115, and the carrier 120 and the transition tube 115 are arranged on the same axis, and the carrier 120 can rotate relative to the transition tube 115. The sleeve connection here means that the inner surface of the carrier 120 is sleeved on the outer surface of the transition tube 115, or the outer surface of the carrier 120 is sleeved on the inner surface of the transition tube 115. In this embodiment, the outer surface of the carrier 120 is sleeved on the inner surface of the transition tube 115, the outer diameter of the carrier 120 is smaller than the inner diameter of the transition tube 115, and the inner wall of the transition tube 115 is provided with a connecting column 1151, the caliber of the connecting column 1151 is adapted to the caliber of the carrier 120, and the carrier 120 is connected to the connecting column 1151. In this way, after the carrier 120 and the transition tube 115 are connected, the inner wall is smoother and has no step structure. When the object 101 to be tested is placed, the object 101 to be tested falls more smoothly in the process of reaching the bottom cover 122 from the placement port 111, reducing the sense of frustration of the transition step. Optionally, the transition tube 115 is fixedly connected to the box 110 through a connector 116. In order to better prevent the object 101 to be tested that enters the placement port 111 from sliding down under the action of gravity, the box 110 is usually in a normal placement state, that is, the plane where the bottom of the box 110 is located is roughly a horizontal plane, and the axis of the carrier 120 is set at an angle of 20 to 80 degrees with the bottom plane of the box 110. That is, the carrier 120 is installed at an angle, such as an angle of 30 degrees, 45 degrees, 50 degrees or 60 degrees, so that the object 101 to be tested can slide along the groove 123, so that the object 101 to be tested after sliding down reaches the bottom cover 122 of the groove 123, so as to improve the shape recognition accuracy. Optionally, the identification component 130 may adopt an infrared sensor, an ultrasonic sensor or a laser sensor, etc., and the first driving member 141 may adopt a driving motor, which is not specifically limited here.

[0060] Please refer to Figure 8 and Fig. 9Furthermore, a feedback mechanism 150 is also provided on the box 110, and the feedback mechanism 150 includes a coin dispenser 151 and / or a printer. The coin dispenser 151 is used to release coins 1501 when the object 101 to be tested in the carrier 120 is turned over to the first storage cavity 10, and the printer is used to print out an identification code when the object 101 to be tested in the carrier 120 is turned over to the first storage cavity 10. For example, the object detection and identification device 100 is used in the field of automatic recycling of items. If a user puts the object 101 to be tested into the inlet 111, and the object 101 to be tested meets the preset requirements and is stored in the first storage cavity 10, the coin dispenser 151 spits out a corresponding number (one or more) of coins 1501 to reward the user; or, the printer prints out an identification code, including but not limited to a barcode or a QR code, and the user can scan and identify the code through a mobile phone or other mobile terminal device to obtain corresponding cash or points as a reward. Among them, the points can be withdrawn or exchanged for goods, etc., which is not specifically limited here. At least one of the coin dispenser 151 and the printer can be provided, or both can be provided at the same time. The printer can be a barcode (or two-dimensional code) printer currently available on the market, which is not specifically limited here.

[0061] It is easy to understand that if the object 101 to be tested does not meet the preset requirements, that is, the object 101 to be tested is flipped and moved to the second storage cavity 30, it means that the delivery is invalid, and the feedback mechanism 150 will not make a coin spitting or barcode printing action. Optionally, the box body 110 is provided with a discarding port 113 connected to the second storage cavity 30, and the bottom surface of the second storage cavity 30 is tilted downward so that the items in the second storage cavity 30 can slide out of the box body 110 from the discarding port 113 under the action of gravity. Figure 3 .

[0062] Optionally, the coin dispenser 151 includes a coin storage barrel 152, a support plate 153, a rotating disk 154, and a second driving member 155. The support plate 153 is installed in the box body 110. The coin storage barrel 152 is fixed to the inner wall of the box body 110 and is arranged above the support plate 153. The coin storage barrel 152 is a hollow cylinder with both ends penetrated, and is used to store coins 1501. The cross-sectional size of the coin storage barrel 152 is adapted to the size of a single coin 1501, that is, the coins 1501 can only be stored in the coin storage barrel 152 in a single stacked manner, and the bottom coin 1501 is located on the support plate 153. The distance between the bottom of the coin storage barrel 152 and the surface of the support plate 153 is the thickness of 1 to 2 coins 1501. In this embodiment, the first coin 1501 on the support plate 153 has no contact with the lower edge of the coin storage barrel 152, and the second coin 1501 on the support plate 153 has not completely separated from the coin storage barrel 152, and a part of its thickness is located in the coin storage barrel 152. This arrangement is conducive to controlling that only one coin 1501 is released to the user each time, and the coin 1501 at the bottom is ejected more smoothly, and the structure is more reliable.

[0063] The box body 110 is provided with a coin storage port 156 connected with the coin storage tube 152, so as to facilitate the storage of coins 1501 in the coin storage tube 152. The support plate 153 is provided with a through hole 1531, and the box body 110 is provided with a coin dispensing port 157 connected with the through hole 1531; the second driving member 155 is connected with the rotating disk 154, driving the rotating disk 154 to rotate so that the rotating disk 154 pushes the coins 1501 in the coin storage tube 152 to the through hole 1531, and the coins 1501 fall to the coin dispensing port 157 through the through hole 1531, so as to facilitate the user to take them out. Optionally, the rotating disk 154 is provided with a rotating shaft 158, which passes through the support plate 153 and is connected with the second driving member 155, and the rotating disk 154 is provided with a pushing part 1543, which is arc-shaped and adapted to the circumferential surface of the coin 1501, so as to facilitate the smooth pushing of the coin 1501. The rotating disk 154 is arranged close to the supporting plate 153, and the thickness of the rotating disk 154 is less than or equal to the thickness of a coin 1501, so that during the rotation of the rotating disk 154, only one coin 1501 is pushed out each time, and the pushed out coin 1501 is the coin 1501 located at the bottom of the coin storage tube 152 (i.e., the first coin 1501 on the supporting plate 153). Of course, in other optional embodiments, if the number of coins 1501 ejected each time is set to be two or more, the thickness of the rotating disk 154 should be adapted to the sum of the thicknesses of the set number of coins 1501, which is not specifically limited here.

[0064] Furthermore, a notch 1541 is provided on the rotating disk 154, and a rotation stop sensor 159 is installed in the box 110. The rotation stop sensor 159 is connected to the second driving member 155, and the rotation stop sensor 159 is used to detect the position of the notch 1541 to control the second driving member 155 to stop rotating. In this embodiment, the rotating disk 154 is not a complete whole disk, and a part is missing to form the notch 1541. The rotating shaft 158 ​​is an eccentric shaft. The rotation stop sensor 159 is blocked by the rotating disk 154 in the default state. When the rotating disk 154 rotates, the notch 1541 on the rotating disk 154 moves accordingly. When the notch 1541 moves to a position opposite to the rotation stop sensor 159, the rotation stop sensor 159 is not blocked by the rotating disk 154. When the rotating disk 154 continues to rotate, the rotation stop sensor 159 is blocked by the rotating disk 154 again. At this time, the second driving member 155 is controlled to stop rotating, that is, the rotating disk 154 is controlled to rotate only one circle each time to push the coin 1501 once. After the object 101 to be tested is effectively placed once, the turntable 154 rotates one circle, pushing the coin 1501 at the bottom layer to move to the through hole 1531, and then falling to the coin dispensing port 157, completing the coin dispensing. It is easy to understand that after the turntable 154 pushes the coin 1501 at the bottom layer to move, the coins 1501 in the coin storage tube 152 fall under the action of gravity, and the second to last coin 1501 under the coin storage tube 152 falls onto the support plate 153, waiting to be pushed by the turntable 154 next time. It should be noted that there are many ways to set the notch 1541 on the turntable 154, which can be any shape, and is not specifically limited here.

[0065] The object detection and identification device 100 also includes a controller 160, which is respectively connected to the identification component 130, the signal light, the first driving member 141, the rotation stop sensor 159 and the second driving member 155. The second driving member 155 can be a driving motor, and the rotation stop sensor 159 can be a proximity switch, a photosensitive sensor or other sensors. In the two cases of shielding and unshielding, high-level and low-level signals are respectively sent to the controller 160, so that the controller 160 controls the second driving member 155 to stop working. The controller 160 is used to receive signals from each detection head to control the signal light to light up or go out; the controller 160 is also used to determine whether the object to be detected 101 meets the preset requirements according to the signals from each detection head. The controller 160 can store a judgment program in advance to control the first driving member 141 to rotate clockwise or counterclockwise to classify the object to be detected 101. If the object 101 to be tested meets the requirements, the controller 160 controls the first driving member 141 to start, driving the carrier 120 to flip along a first direction, such as a clockwise direction, so that the object 101 to be tested on the carrier 120 falls into the first storage cavity 10 of the box 110. If the object 101 to be tested does not meet the requirements, the controller 160 controls the first driving member 141 to start, driving the carrier 120 to flip along a second direction, such as a counterclockwise direction, so that the object 101 to be tested on the carrier 120 falls into the second storage cavity 30 of the box 110, thereby realizing automatic classification of the object 101 to be tested. The controller 160 is also used to control the printer to print an identification code after the object 101 to be tested moves to the first storage cavity 10, and / or control the coin dispenser 151 to dispense coins.

[0066] Optionally, the controller 160 may be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it may also be a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. Of course, the controller 160 may also be integrated into a PLC controller, a single-chip microcomputer, etc., which is not specifically limited here.

[0067] It is easy to understand that the drive motor can be powered by a battery, an external power supply, or a solar power supply device. The use of a battery or a solar power supply device is not limited by the place of use, has a wider range of applications, is more convenient to install, and is easy to carry and move. The object detection and recognition device 100 has a simple structure, is easy to manufacture, has a low processing cost, has a wide range of application scenarios, a simple recognition principle, high accuracy, and high classification efficiency, and has great promotion and application value.

[0068] The embodiment of the present invention further provides an object detection and recognition method, comprising:

[0069] Obtain the shape parameters of the object to be tested 101; judge the shape parameters and the preset parameters; if the shape parameters are within the preset parameter range, control the first driving member 141 to drive the carrier 120 to move the object to be tested 101 to the first storage cavity 10 in the box 110; if the shape parameters are outside the preset parameter range, control the first driving member 141 to drive the carrier 120 to move the object to be tested 101 to the second storage cavity 30 in the box 110. Optionally, the object detection and identification method can be applied to the object detection and identification device 100 in the aforementioned embodiment, the object detection and identification device 100 includes a box 110 and a carrier 120 and an identification component 130 disposed in the box 110, the carrier 120 is used to install the object to be tested 101, and the identification component 130 includes a plurality of detection heads, and the plurality of detection heads are disposed on the periphery of the carrier 120.

[0070] A plurality of detection heads are arranged along a first preset direction to detect the length dimension of the object to be detected 101 in the first preset direction; the preset parameters include a first reference distance and a second reference distance, in the first preset direction, the distance between two detection heads is the first reference distance, and the distance between the other two detection heads is the second reference distance. If the length dimension in the first preset direction is greater than or equal to the first reference distance, and less than or equal to the second reference distance, the object to be detected 101 moves to the first storage cavity 10; if the length in the first preset direction is less than the first reference distance, or greater than the second reference distance, the object to be detected 101 moves to the second storage cavity 30.

[0071] Optionally, there are four detection heads, which are arranged at intervals along the axis of the carrier 120, and from the bottom cover 122 of the carrier 120 to the opening 121, they are the first detection head 131, the second detection head 132, the third detection head 133 and the fourth detection head 134. The four detection heads are mounted on the mounting plate 128, and the mounting plate 128 can be connected to the carrier 120 or the box 110, which is not specifically limited here.

[0072] The distance between the first detection head 131 and the third detection head 133 is used as the first reference distance in the preset parameters, and the distance between the first detection head 131 and the fourth detection head 134 is used as the second reference distance in the preset parameters. That is, the object 101 to be detected enters the groove 123 of the carrier 120 from the delivery port 111 of the box 110, and the first detection head 131, the second detection head 132 and the third detection head 133 detect obstacles at the same time, that is, the indicator lights of the first detection head 131, the second detection head 132 and the third detection head 133 are all on at the same time, and the fourth detection head 134 does not detect obstacles, and the indicator light of the fourth detection head 134 is off, indicating that the length of the object 101 to be detected is within the required range. At this time, the controller 160 controls the driving motor to rotate clockwise, and the object 101 to be detected in the groove 123 is flipped and dropped into the first storage cavity 10 of the box 110.

[0073] If only the first detection head 131 and the second detection head 132 detect an obstacle, that is, the indicator lights of the first detection head 131 and the second detection head 132 are on, it means that the length of the object to be measured 101 is less than the preset parameter, which does not meet the requirements. If only the first detection head 131 detects an obstacle, that is, only the indicator light of the first detection head 131 is on, it means that the length of the object to be measured 101 is less than the preset parameter, which does not meet the requirements. If the first detection head 131, the second detection head 132, the third detection head 133 and the fourth detection head 134 all detect obstacles, that is, the indicator lights of the first detection head 131, the second detection head 132, the third detection head 133 and the fourth detection head 134 are all on, it means that the length of the object to be measured 101 is greater than the preset parameter, which does not meet the requirements. If the obstacle is detected to be empty, that is, all detection heads do not detect obstacles, which does not meet the requirements. If the first detection head 131 does not detect an obstacle, and at least one other detection head detects an obstacle, it means that the object to be measured 101 has not fallen to the bottom cover 122 of the carrier 120, which also does not meet the requirements. In any of the above situations that do not meet the requirements, the controller 160 will control the driving motor to rotate counterclockwise, flip the object 101 in the groove 123 and drop it into the second storage cavity 30 of the box 110, and then discharge it out of the box 110 from the discarding port 113.

[0074] In this embodiment, four detection heads are used, and the layout is simple, which can meet the requirements of length detection of the object 101 to be detected, has high classification and recognition efficiency, is easy to install, has strong operability, and has low manufacturing cost, which is conducive to popularization and promotion of application. It should be noted that in this embodiment, only four detection heads are arranged in a straight line to illustrate the length detection principle of the object 101 to be detected. In other optional implementations, the number of detection heads can also be two, three, five, six or more, and the layout of the detection heads can also be circular, elliptical, square, diamond or other arbitrary shapes, which can be flexibly set according to the actual detection target, and no specific limitation is made here.

[0075] Furthermore, the object detection and identification method also includes triggering the action of the feedback mechanism 150 after the object to be detected 101 moves to the first storage cavity 10, and the feedback mechanism 150 spits out coins 1501 and / or prints out an identification code outside the box 110, which is used to reward the user who puts the object to be detected 101. Optionally, the coin dispenser 151 can spits out a corresponding number (one or more) of coins 1501 to reward the user; or, the printer prints out an identification code, including but not limited to a barcode or a QR code, and the user can scan and identify the code through a mobile phone or other mobile terminal device to obtain corresponding cash or points as a reward. Among them, the points can be withdrawn or exchanged for goods, etc., which is not specifically limited here.

[0076] Optionally, multiple detection heads are arranged along the second preset direction to detect the length dimension of the object to be detected 101 in the second preset direction, such as detecting the width of the object to be detected 101, and judging whether the width of the object to be detected 101 meets the detection requirements; and / or, multiple detection heads are arranged along the third preset direction to detect the length dimension of the object to be detected 101 in the third preset direction, such as detecting the height or thickness of the object to be detected 101, and judging whether the height or thickness of the object to be detected 101 meets the detection requirements. In addition, it is also possible to detect and judge the part of the object to be detected 101, and adjust the layout position of the detection head according to the target parameters. The detection and judgment principle is similar to the above-mentioned length detection principle, and is not specifically limited here.

[0077] It is easy to understand that the controller 160 stores preset parameters, and the controller 160 is used to receive the shape parameters detected by the identification component 130, and compare the preset parameters with the shape parameters. If the shape parameters are within the preset parameter range, the controller 160 is used to control the first driving member 141 to rotate in the first direction, so that the carrier 120 flips in the first direction, and the object to be tested 101 is moved to the first storage cavity 10; if the shape parameters are outside the preset parameter range, the controller 160 is used to control the first driving member 141 to rotate in the second direction, so that the carrier 120 flips in the second direction, and the object to be tested 101 is moved to the second storage cavity 30.

[0078] In summary, the embodiments of the present invention provide an object detection and recognition device 100 and an object detection and recognition method, which have the following beneficial effects:

[0079] The object detection and identification device 100 and the object detection and identification method can be used for rapid identification and classification of the object 101 to be detected, and have a simple and compact structure, a small size, and are easy to move and carry; the use site is not restricted, the installation is convenient, the use flexibility is high, the classification efficiency is high, the operability is strong, the production cost is low, and there are corresponding reward feedbacks for users who put in effective placements, which is conducive to the implementation of popularization and promotion of application. It can not only solve the defects of the existing technology of high intensity, time-consuming and labor-intensive manual classification, but also solve the technical problem of high cost of intelligent image recognition.
