Description

Technical Field

[0002] In product packaging, it is usually necessary to set signs reflecting product type, specifications, batch and other information in specific areas of the packaging container (such as cardboard boxes, wooden boxes, etc.).

However, manual visual inspection is inefficient and labor-intensive, failing to meet the demands of automated production lines and prone to false positives and missed detections. Therefore, there is an urgent need for a new inspection method that can automatically detect markings on packaging containers and determine whether the information carried by these markings matches pre-set information, thereby improving production line automation.

However, those skilled in the art will appreciate that many technical details are provided in various embodiments of the present invention to facilitate a better understanding of the present application. However, even without these technical details and the various variations and modifications based on the following embodiments, the technical solutions claimed in the claims of this application can be achieved.

[0024] In the embodiments of the present invention, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," "outer," "center," "vertical," "horizontal," "transverse," and "longitudinal" to indicate directions or positions are based on the directions or positions shown in the accompanying drawings.

[0025] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0026] Furthermore, the terms "installed," "set," "provided with," "opened," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0027] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0028] Product packaging, such as photovoltaic cell packaging, often requires labels, markings, and other information to convey product-related information, including cell specifications, company information, product instructions, and customer information. Some of this information needs to be directly readable on these markings to determine whether the actual product matches the packaging and whether any labeling is missing. However, these inspections and the determination of test results are largely performed manually, resulting in low production efficiency and prone to false detection and missed detection due to manual fatigue.

[0029] In order to solve the above technical problems, an embodiment of the present invention provides an automatic label identification device for automatically identifying label information on a packaging container, the automatic label identification device comprising: a first identification and detection mechanism for automatically acquiring first label information on the packaging container on one side of the packaging container, and identifying whether the first label information matches the first target information; a second identification and detection mechanism, arranged opposite to the first identification and detection mechanism, for automatically acquiring second label information on the other side of the packaging container, and identifying whether the second label information matches the second target information; a conveying mechanism, located between the first identification and detection mechanism and the second identification and detection mechanism, the conveying mechanism being used to carry and transport the packaging container.

[0030] The automatic label recognition device of the present embodiment utilizes a conveying mechanism to transport the packaging container between a first recognition and detection mechanism and a second recognition and detection mechanism. This allows for simultaneous automatic detection on opposite sides of the packaging container, with the detection range covering a large portion of the packaging container. After detecting the corresponding label information, the first and second recognition and detection mechanisms further identify the corresponding label information to determine whether the label information matches the corresponding target information. This improves detection efficiency, avoids false detections and missed detections, reduces labor costs, and improves automated production efficiency.

[0031] It should be noted that the automatic label identification device of the present invention can also be connected to MES (Manufacturing Execution System), and cooperate with MES to realize automatic work dispatch, call detection formulas, etc., and use MES to cooperate with the transmission mechanism to control the detection rhythm and automatically classify the packaging containers that have completed the inspection according to the inspection results.

[0032] The following is a detailed description of the implementation details of the automatic label identification device of this embodiment. The following content is only provided for easy understanding of the implementation details and is not necessary for implementing this solution.

[0033] See also Figure 1, a hexahedral packaging carton is used as a packaging container for illustration. Generally speaking, for ease of identification, at least one mark (such as a card, mark or label) is set on multiple outer surfaces of the carton. Therefore, when detecting whether the mark matches the product and whether the information carried by the mark is correct, it is necessary to simultaneously detect and judge the marks on multiple outer surfaces of the carton. The automatic label identification device 1000 of this embodiment includes a first identification detection mechanism 100 and a second identification detection mechanism 200 that are relatively arranged, and a conveying mechanism 300 located between the first identification detection mechanism 100 and the second identification detection mechanism 200. The conveying mechanism 300 is used to carry the carton and transport the carton between the first identification detection mechanism 100 and the second identification detection mechanism 200. The first identification detection mechanism 100 automatically obtains the first label information on the carton on one side of the carton and identifies whether the first label information matches the first target information; and the second identification detection mechanism 200 automatically obtains the second label information on the carton on the other side of the carton and identifies whether the second label information matches the second target information.

[0034] By positioning the first recognition and detection mechanism 100 and the second recognition and detection mechanism 200 relative to each other and performing detection and identification on different sides of the carton, the detection range can cover most areas on the carton, avoiding missed detections. The first recognition and detection mechanism 100 and the second recognition and detection mechanism 200 can use sensors to obtain the shape, size, position, and information carried by the mark on the carton, and then perform identification to confirm whether the mark on the carton matches a preset target mark and whether the information carried by the mark matches the preset target information. This can save labor, improve detection efficiency, and avoid false detections.

[0035] It is understandable that the first tag information and the second tag information may be the same or different. Similarly, depending on whether the first tag information and the second tag information are the same, the first target information and the second target information may also be set to be the same or different.

[0036] See also Figure 2 and Figure 3 The first recognition and detection mechanism 100 includes a first camera 110 and a first adjustment component. The first camera is fixed to the first adjustment component, and the first adjustment component is used to adjust the position of the first camera 110. The first camera 110 is used to automatically obtain the first tag information and automatically recognize the obtained first tag information. The first adjustment component can increase or change the detection range of the first camera 110 by changing the position of the first camera 110 to meet different actual detection requirements.

[0037] See also Figure 2The first adjustment assembly includes a vertical motion structure 120 and a first horizontal motion structure 130. The first horizontal motion structure 130 is fixedly connected to the vertical motion structure 120, and the first camera 110 is disposed on the first horizontal motion structure 130. The vertical motion structure 120 can drive the first horizontal motion structure 130 to move in the vertical direction so as to detect the mark on the carton at an appropriate height, and the first horizontal motion structure 130 can drive the first camera 110 to move in the horizontal direction so as to detect the mark on the carton at an appropriate horizontal position. It is understandable that the vertical motion structure 120 can also be disposed on the first horizontal motion structure 130, and then the first camera 110 can be disposed on the vertical motion structure 120. In this case, the first horizontal motion structure 130 drives the vertical motion structure 120 to drive the first camera 110 to move in the horizontal direction, while the vertical motion structure 120 drives the first camera 110 to move in the vertical direction.

[0038] Optional, see again Figure 2 The vertical motion structure 120 may include a vertical rail 121, a first slider 122, and a first cylinder 123. The first slider 122 is movably disposed on the vertical rail 121. The piston of the first cylinder 123 is fixedly connected to the first slider 122. The first cylinder 123 drives the first slider 122 to move in the vertical direction through the piston. The first horizontal motion structure 130 is fixedly connected to the first slider 122. Specifically, the first slider 122 is provided with a structure that can cooperate with the vertical rail 121, so that the first slider 122 can only move in the vertical direction on the vertical rail 121. The first cylinder 123 can be disposed at either end of the vertical rail 121, such as the bottom end. The piston of the first cylinder 123 is connected to the first slider 122. The first cylinder 123 can push the first slider 122 to move on the vertical rail 121 through the piston, thereby driving the first camera 110 and the first horizontal motion structure 130 to move in the vertical direction.

[0039] Alternatively, the vertical motion structure 120 may include a vertical track, a slider, a screw (not shown), and a motor (not shown). The slider is movably disposed on the vertical track. The motor is fixed to one end of the vertical track. The screw is coaxially fixedly connected to the motor's rotating shaft. The slider also has a screw hole, which passes through the screw hole and engages with the slider thread. The motor drives the slider to move in the vertical direction via the screw. The horizontal motion structure is fixedly connected to the slider. It is understood that the slider can only move in the vertical direction relative to the vertical track and cannot rotate relative to the vertical track. The screw hole of the slider extends in the same direction as the movement direction of the slider. The screw passes through the screw hole and the two are threadedly engaged. The vertical track, slider, and screw constitute a screw-slider transmission mechanism. When the motor's rotating shaft rotates, the screw rotates synchronously. Since the slider cannot rotate relative to the vertical track, the slider is driven by the screw and moves along the vertical track, thereby driving the first camera 110 and the first horizontal motion structure 130 in the vertical direction. The type and specification of the motor can be selected according to actual conditions. For example, a servo motor can be used, which has higher control accuracy.

[0040] Alternatively, the vertical motion structure 120 includes a conveyor belt (not shown), a fixed base (not shown), a motor (not shown), and multiple rollers (not shown). The multiple rollers are arranged in a vertical direction at intervals, with the axial directions of the multiple rollers perpendicular to the arrangement direction. The conveyor belt is disposed around the outer circumference of the multiple rollers and frictionally engages with the surfaces of the multiple rollers. The motor's rotating shaft is coaxially and fixedly connected to any one of the rollers. The horizontal motion structure is fixed to the conveyor belt, and the first camera 110 is fixed to the fixed base. For example, there can be two rollers, spaced apart, with the conveyor belt surrounding the outer circumference of the two rollers. When the motor is operating, the rollers rotate with the motor's rotating shaft, driving the conveyor belt to move up and down, thereby causing the fixed base on the conveyor belt to move up and down. Because the horizontal motion structure 130 is fixed to the fixed base, the first camera 110 and the first horizontal motion structure 130 also move in the vertical direction.

[0041] Similarly, see Figure 2 The first horizontal motion structure 130 may include a first horizontal rail 131, a second slider 132, and a second cylinder 133. The second slider 132 is movably disposed on the first horizontal rail 131. The piston of the second cylinder 133 is fixedly connected to the second slider 132. The second cylinder 133 drives the second slider 132 to move horizontally via the piston. The first camera 110 is fixedly connected to the second slider 132. Specifically, the second slider 132 is configured to move only horizontally on the first horizontal rail 131. The second cylinder 133 is disposed at either end of the first horizontal rail 131. When the second cylinder 133 is in operation, its piston drives the second slider 132 to move on the first horizontal rail 131, thereby driving the first camera 110 to move horizontally.

[0042] Alternatively, the first horizontal motion structure 130 includes a horizontal track, a slider, a screw (not shown) and a motor (not shown). The slider is movably arranged on the horizontal track, the motor is fixed to one end of the horizontal track, the screw is coaxially fixedly connected to the rotating shaft of the motor, and the slider is also provided with a screw hole, the screw passes through the screw hole and cooperates with the slider thread. The motor drives the slider to move in the horizontal direction through the screw, and the first camera is fixedly connected to the slider. Similarly, the horizontal track, the slider and the screw cooperate with each other to form a screw and slider transmission mechanism, which can convert the rotational motion of the rotating shaft of the motor into the horizontal linear motion of the slider. In this way, when the motor is working, the slider moves along the horizontal track under the action of the screw, thereby driving the first camera 110 to move horizontally.

[0043] Alternatively, the first horizontal motion structure 130 includes a conveyor belt (not shown), a fixed base (not shown), a motor (not shown), and multiple rollers (not shown). The multiple rollers are arranged in a horizontal direction at intervals, and the axial directions of the multiple rollers are perpendicular to the arrangement direction. The conveyor belt is arranged around the outer periphery of the multiple rollers and frictionally engages with the surfaces of the multiple rollers. The motor's rotating shaft is coaxially fixedly connected to any one of the rollers. The fixed base is fixed to the conveyor belt, and the first camera is fixed to the fixed base. Similar to the vertical motion structure 120 using a conveyor belt, when the motor of the first horizontal motion structure 130 is in operation, its rotating shaft drives one roller to rotate, causing the fixed base fixed to the conveyor belt to move horizontally, thereby causing the first camera 110 fixed to the fixed base to move horizontally. It is understood that the conveyor belt can be a belt, a crawler track, or a similar structure, and this embodiment does not specifically limit this.

[0044] In this embodiment, the first adjustment assembly further includes an angle adjustment structure 140 disposed on the first horizontal motion structure 130. The first camera 110 is disposed on the angle adjustment structure 140. The angle adjustment structure 140 is used to drive the first camera 110 to rotate. The first horizontal motion structure 130 drives the angle adjustment structure 140 to move the first camera 110 horizontally. It is understood that the angle adjustment structure 140 can be disposed on the second slider 132 of the first horizontal motion structure 130.

[0045] Optional, see Figure 3, the angle adjustment structure 140 may include a motor 141 and a carrier 142. The motor 141 is fixed to the horizontal motion structure 130 (specifically, the second slider 132). The carrier 142 is connected to the rotating shaft of the motor 141. The first camera 110 is fixed on the carrier 142. The motor 141 drives the carrier 142 to drive the first camera 110 to rotate. Specifically, the rotating shaft of the motor 141 is fixedly connected to the carrier 142. The first camera 110 is fixed to the side of the carrier 142 away from the motor 141. When the rotating shaft of the motor 141 rotates, the first camera 110 can be driven to rotate through the carrier 142 to adjust the detection angle of the first camera 110 relative to the carton to adapt to actual detection needs. In some designs, the rotating shaft of the motor 141 and the carrier 142 can also be connected by a deceleration mechanism to better control the rotation speed of the carrier 142.

[0046] Alternatively, the angle adjustment structure 140 includes a motor, a support platform, a driving gear (not shown), and a driven gear (not shown). The driving gear is fixed to the motor's shaft, the driven gear is fixed to the support platform, and the support platform is rotatably fixed to the horizontal motion structure. The driving gear and the driven gear are engaged, and the motor's shaft drives the driving gear to rotate the driven gear, so that the support platform drives the first camera 110 to rotate. Specifically, the support platform 142 can be fixed to the second slider 132 via a support shaft (not shown), and the support shaft is connected to the second slider 132 via a rotary bearing, so that the support shaft can rotate relative to the second slider 132. The motor is also fixed to the second slider 132. The axis of the motor's rotating shaft is parallel to the axis of the support shaft. The driving gear is coaxial with the motor's rotating shaft and is fixed to the motor's rotating shaft. The driven gear is coaxial with the support shaft and is fixed to the support shaft. The driving gear and the driven gear are engaged. When the motor is working, the rotating shaft drives the driving gear to rotate, and the driving gear drives the driven gear to drive the supporting platform 142 to rotate. In this way, the first camera 110 fixed to the supporting platform 142 also rotates synchronously.

[0047] Similar to the first recognition and detection mechanism 100, the second recognition and detection mechanism 200 includes a second camera 210 and a second adjustment assembly. The second camera 210 is fixed to the second adjustment assembly and is used to automatically capture the second label information on the carton and determine whether the second label information matches the second target information. The second adjustment assembly can be used to drive the second camera 210 to change its detection position, expand its detection range, and move it to a suitable detection position, thereby improving the accuracy of the detection results.

[0048] See also Figure 4The second adjustment component may include a second horizontal motion structure 220 , the second camera 210 is fixed to the second horizontal motion structure 220 , and the second horizontal motion structure 220 is used to drive the second camera 210 to move in the horizontal direction to adjust the detection position of the second camera 210 .

[0049] It is understood that the second horizontal motion structure 220 can be configured with reference to the first horizontal motion structure 120, which is not described in detail here. In addition, the second adjustment component can also refer to the first adjustment component to further configure a vertical motion structure and an angle adjustment structure, which is not described in detail here.

[0050] Optionally, the first camera 110 and the second camera 210 may be AI cameras, CCD cameras, or other visual devices capable of automatically acquiring information related to markings on cartons. When the first camera 110 and the second camera 210 are AI cameras, they inherently have the ability to process data and, after acquiring information about the cardboard, shipping mark, and label on specific areas of the cartons, can automatically perform identification and analysis.

[0051] See again Figure 3 In this embodiment, the first identification and detection mechanism 100 may further include a code reader 150 disposed on the carrier 142. The code reader 150 may be used to read the QR code on the cartons. Based on the scanned code result, the MES is linked to retrieve the inspection recipe and send the inspection recipe to the first camera 110 and the second camera 210. It should be noted that the inspection recipe is the position, size, number, combination, and information carried by the card, mark, and label corresponding to a specific product on the carton.

[0052] The conveyor mechanism 300 includes a conveyor belt 310 and a position detector (not shown). The position detector is located at a detection position on the conveyor belt 310. The conveyor belt 310 is used to carry and transport cartons, and the position detector is used to detect whether a carton is present at the detection position. This allows the barcode reader 150 to be activated and the MES to be linked only when a carton is detected at the detection position, thus avoiding resource waste.

[0053] Optionally, the position detector may be a pressure sensor, an optical sensor, or another type of sensor, as long as the position detector can accurately detect whether there is a carton at the detection position.

[0054] The conveyor belt 310 has a first discharge port (not shown) and a second discharge port (not shown). When the first label information does not match the first target information, and / or the second label information does not match the second target information, it indicates that the packaging does not meet the requirements, and the conveyor belt 310 conveys the carton to the first discharge port. When the first label information matches the first target information, and the second label information matches the second target information, it indicates that the packaging meets the requirements, and the conveyor belt 310 conveys the carton to the second discharge port. It is understood that when the carton is conveyed to the first discharge port, it can be manually removed and repackaged and repaired; when the carton is conveyed to the second discharge port, the next packaging process can be carried out.

[0055] See again Figure 2 and Figure 4 The first identification and detection mechanism 100 and the second identification and detection mechanism 200 can respectively include heightening brackets 160 and 230. Since the conveyor belt 310 itself has a certain height, the height of the camera and the adjustment component can be raised by raising the brackets 160 and 230 to perform height compensation, and avoid unnecessary interference between the camera and the adjustment component and the conveyor belt 310.

[0056] See also Figure 5 The automatic tag identification device 1000 further includes a first fence 500 and a second fence 600. The first fence 500 is disposed around the first identification and detection mechanism 100, enclosing the first identification and detection mechanism 100; the second fence 600 is disposed around the second identification and detection mechanism 200, enclosing the second identification and detection mechanism 200. The first fence 500 and the second fence 600 provide protection for the first and second identification and detection mechanisms 100 and 200, preventing operators or other equipment from interfering with the operation of the first and second adjustment assemblies.

[0057] In this embodiment, the automatic label recognition device 1000 further includes a control mechanism (not shown), which is electrically connected to the first recognition and detection mechanism 100, the second recognition and detection mechanism 200, and the conveying mechanism 300. The control mechanism is used to control at least one of the first recognition and detection mechanism 100, the second recognition and detection mechanism 200, and the conveying mechanism 300 according to preset conditions. For example, the control mechanism 400 can control the vertical motion structure 120, the first horizontal motion structure 130, and the angle adjustment structure in the first recognition and detection mechanism 100, and can control the second horizontal motion structure 220, the vertical motion structure (if any), and the angle adjustment structure (if any) in the second recognition and detection mechanism 200. It can also control the start and stop, movement speed, etc. of the conveying mechanism 300, and can also obtain the detection results of the first camera 110 and the second camera 210, and control the conveying mechanism 300 to transport the carton to the first unloading port or the second unloading port according to the detection results. It should be noted that the "preset conditions" are formed according to the detection formula. The detection formula contains information about the setting position, size, etc. of the brackets, marks and labels. The control mechanism can control the positions of the first camera 110 and the second camera 210 respectively through the first adjustment component and the second adjustment component based on this information, so that the first camera 110 and the second camera 210 can perform detection at the optimal position corresponding to the detection formula.

[0058] It is understandable that the control mechanism can be a power mechanism used alone to control the first identification and detection mechanism 100, the second identification and detection mechanism 200 and the transmission mechanism 300, or it can be a part of the MES, and the present invention does not make any specific limitation.

[0059] To better illustrate the automatic label identification device 1000 of this embodiment, the following describes part of the production and testing process of a production line equipped with the device:

[0060] First, a carton with a specific mark is manually placed on the conveyor belt 310, and the control mechanism 400 activates the conveyor mechanism 300 to transport the carton to the inspection position;

[0061] The carton is transported to the inspection position by the conveyor belt 310. The position detector detects the carton, and the code reader 150 obtains the tow number QR code and links with the MES to obtain the inspection recipe. The inspection recipe carries the target information. The first camera 110 and the second camera 210 obtain the corresponding label information and identify and analyze the obtained label information with the target information.

[0062] If the label information does not match the target information, a message indicating that the material does not meet the requirements will be sent to the MES, the pallet will be removed from the matching sequence, and the carton will be transported to the first unloading port, where it will be manually taken away and returned for repair.

[0063] If the label information matches the target information, the information that the material meets the requirements is sent to the MES, and the carton is transported to the second unloading port to pair the two pallet components, and then transferred normally to the warehouse to wait for shipment.

[0064] The above is a detailed introduction to the automatic label identification device provided by the embodiment of the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above implementation methods is only used to help understand the idea of ​​the present invention. There may be changes in the specific implementation methods and application scope. In summary, the contents of this specification should not be understood as limiting the present invention.
