TECHNICAL FIELD

[0001] The application relates to the technical field of labeling equipment, and in particular to a full-automatic positioning and labeling device based on a CCD. BACKGROUND

[0002] In modern industrial production, labeling is an important step in product packaging. With the rapid development of various industries, the types of products are increasingly diverse, and the quality and efficiency of product packaging are continuously improved. At present, the traditional labeling device gradually exposes many problems in practical application. For example, its positioning accuracy cannot meet the needs of diversified products, and when facing different shapes and sizes of objects, it is often difficult to accurately paste labels at the specified position. Some labeling machines rely on manual positioning assistance, which is not only inefficient, but also prone to large errors in manual operation, resulting in inconsistent label attachment positions and affecting the overall appearance and packaging quality of products.

[0003] Therefore, based on the above problems, the prior art needs to be improved. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the application is to provide a full-automatic positioning and labeling device based on a CCD.

[0005] The above technical purpose of the application is achieved by the following technical scheme: a full-automatic positioning and labeling device based on a CCD, comprising a rack, an X-axis moving assembly arranged on the rack, a Y-axis moving assembly arranged on the X-axis moving assembly, a Z-axis moving assembly arranged on the Y-axis moving assembly, and a labeling assembly arranged on the Z-axis moving assembly; a printer is arranged on the rack to produce label paper; a conveying track is also arranged on the rack to receive and transport workpieces; and a positioning camera is arranged on the rack corresponding to the conveying track.

[0006] By adopting the above technical scheme, full-automatic operation is realized from label production (printer), workpiece transportation (conveying track), positioning (positioning camera and material blocking assembly) to label attachment (labeling assembly), manual intervention is reduced, production efficiency is improved, labor cost is reduced, and labeling errors caused by human factors are reduced. Secondly, through the cooperative work of the CCD vision detection system (positioning camera), X, Y and Z axis moving assemblies and the labeling assembly, the information of the workpiece and the label can be accurately obtained, and the labeling assembly can be accurately moved in three-dimensional space to accurately attach the label to the specified position of the workpiece, effectively control the labeling error, greatly improve the labeling precision and ensure the product packaging quality. Furthermore, the design of each component cooperates with each other, improves the versatility and adaptability of the device, and can adapt to workpieces and label styles of different shapes and sizes, meeting diversified production needs.

[0007] Optionally, by setting the X-axis, Y-axis, Z-axis moving assembly and the labeling assembly, the labeling operation is realized in the space full- range accurate movement, which can adapt to different shapes, sizes and location requirements of workpiece labeling; the printer can produce label paper on demand, ensuring the timeliness and flexibility of label supply; the conveying track facilitates automatic transportation of the workpiece, improving the coherence of the production process; the alignment camera can accurately obtain the workpiece position information, and work with each component to realize ultra-high precision automatic positioning labeling operation, greatly improving the labeling accuracy, ensuring product packaging quality, adapting to a variety of goods and label styles, and fully automated process reduces manual intervention, improves production efficiency, reduces labor costs and reduces human error in labeling, with strong versatility and flexibility, improving the accuracy and efficiency of labeling.

[0008] By adopting the above technical scheme, the X-axis moving assembly includes a first sliding rail, a first sliding block is arranged on the first sliding rail, and a first driving member is connected to the first sliding block. The first driving member drives the first sliding block to slide on the first sliding rail.

[0009] Optionally, the first sliding rail provides a stable sliding track for the first sliding block, ensuring the linearity and stability of movement. The first driving member drives the first sliding block to slide on the first sliding rail, so that the labeling assembly can realize accurate and rapid position adjustment in the X-axis direction. Not only does it ensure the positioning accuracy in the X-axis direction during labeling, effectively avoiding labeling position deviation caused by X-axis direction movement error, but also improves labeling accuracy. Moreover, through the control of the driving member, the speed and position can be flexibly adjusted according to the actual labeling requirements, greatly enhancing the adaptability of the entire device to different sizes and shapes of workpieces in the X-axis direction, helping to improve the versatility and working efficiency of the device, thus better meeting the diversified labeling production requirements.

[0010] By adopting the above technical scheme, by arranging the second sliding rail on the first sliding block, the spatial movement dimension is further expanded on the basis of X-axis movement of the X-axis moving assembly. The second driving member drives the second sliding block to slide on the second sliding rail, so that the labeling assembly can be accurately positioned in the Y-axis direction, and work with the X-axis moving assembly to realize the accessibility of any position in the plane, greatly enhancing the flexibility and accuracy of the labeling position. When facing workpieces and labels of different layouts and shapes, it can effectively ensure the accurate attachment of labels in the Y-axis direction, avoiding the influence of Y-axis direction deviation on labeling quality. At the same time, this structure helps to improve the processing capacity of the entire device for complex labeling tasks, further improving the versatility and adaptability of the device, thus improving the overall efficiency and quality of labeling operations.

[0011] Optionally, the Z-axis moving assembly comprises a third sliding rail arranged on the second sliding block, a third sliding block arranged on the third sliding rail, and a third driving member connected to the third sliding block and configured to drive the third sliding block to slide on the third sliding rail.

[0012] By adopting the above technical solution, the third sliding rail is arranged on the second sliding block, and the moving ability in the vertical direction (Z-axis) is added on the basis of the plane moving of the X-axis and Y-axis moving assemblies. The third driving member drives the third sliding block to slide on the third sliding rail, so that the labeling assembly can accurately adjust the height position in the Z-axis direction. This design makes the labeling device adapt to workpieces of different heights, and accurately meets the labeling requirements of higher or lower positions, further perfecting the positioning function of the device in three-dimensional space. In actual production, various shapes and sizes of articles with large differences can ensure that the label is accurately attached to the specified height position, effectively avoiding labeling failure or poor appearance caused by height deviation. It cooperates with the X-axis and Y-axis moving assemblies to greatly improve the response ability of the whole device to different labeling tasks, improve the labeling precision and operation efficiency, and make the device better serve the packaging needs of diversified products.

[0013] Optionally, the labeling assembly comprises a fourth sliding rail arranged on the third sliding block, a fourth sliding block arranged on the fourth sliding rail, and a fourth driving member connected to the fourth sliding block and configured to drive the fourth sliding block to slide on the fourth sliding rail, and a pneumatic suction head arranged on the fourth sliding block and configured to pick up or release the label paper.

[0014] By adopting the above technical solution, the combination of the fourth sliding rail, the fourth sliding block and the fourth driving member enables the pneumatic suction head to finely adjust the position in a small range, further improving the accuracy of the label attachment position. Even when facing a small labeling position deviation requirement, the label can also be accurately positioned. The pneumatic suction head is arranged to pick up and release the label paper, and its picking process is stable and reliable, which can accurately grasp the label paper produced by the printer. During transportation and position adjustment, the label paper is ensured not to shift or fall off. When releasing, the label paper can be accurately attached to the surface of the workpiece according to the labeling requirements, effectively preventing the label from being attached loosely or wrinkled. This structure makes the labeling process more flexible and accurate, significantly improves the labeling quality, reduces the product failure rate caused by the labeling link, and improves the working efficiency of the whole labeling device.

[0015] Optionally, a label paper holder is arranged at the paper outlet of the printer.

[0016] By adopting the technical scheme, the label paper bracket provides a stable receiving platform for the label paper just output from the printer, effectively prevents the label paper from being offset, curled or falling off due to gravity or other external forces after printing is completed, and ensures that the label paper is always in a correct and stable state before being picked up by the labeling assembly. This helps to improve the success rate and accuracy of the pneumatic suction head picking up the label paper, reduces the picking failure or abnormal posture of the label paper after picking caused by improper initial position of the label paper. At the same time, the stable state of the label paper is conducive to the accurate control of the label paper by the labeling assembly during transportation and labeling, further improving the stability and reliability of the entire labeling process, thereby ensuring the labeling precision and improving the overall efficiency of the labeling operation.

[0017] Optionally, a mounting bracket is arranged on the rack, a surface lamp is arranged on the mounting bracket, and an avoiding through hole is arranged on the surface lamp for avoiding the alignment camera.

[0018] By adopting the technical scheme, the mounting bracket provides a stable mounting position for the surface lamp, ensures that the surface lamp can be stably fixed on the rack, maintains stability during equipment operation, and avoids affecting the lighting effect due to shaking and other factors. The arrangement of the surface lamp can provide sufficient and uniform illumination for the labeling area. Especially in some dark working environments or in cases where the details of the workpiece surface and the characteristics of the label need to be clearly identified, good illumination can help the alignment camera more accurately acquire image information of the workpiece and the label, thereby further improving the positioning and labeling accuracy. The avoiding through hole arranged on the surface lamp cleverly solves the conflict between the surface lamp and the alignment camera in terms of spatial layout, ensures the normal lighting function of the surface lamp, and does not block the field of view of the alignment camera, ensuring that the alignment camera can accurately shoot and position the workpiece on the conveying track without interference, so that the components of the entire device can work cooperatively to improve the accuracy, efficiency and reliability of the labeling operation.

[0019] In summary, the present application at least has the following beneficial effects:

[0020] 1. The entire process from label production (printer), workpiece transportation (conveying track), positioning (alignment camera and material blocking assembly) to label attachment (labeling assembly) is realized automatically, reducing manual intervention, improving production efficiency, reducing labor costs, and also reducing labeling errors caused by human factors.

[0021] 2. Through the cooperative work of the CCD vision detection system (alignment camera), X, Y and Z axis moving assemblies and the labeling assembly, the information of the workpiece and the label can be accurately acquired, and the labeling assembly can be accurately moved in three-dimensional space to accurately attach the label to the specified position of the workpiece, effectively control the labeling error, greatly improve the labeling precision and ensure the product packaging quality.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] In this embodiment, refer to Figures 1-3 A CCD-based fully automatic positioning and labeling device includes a frame 1, an X-axis moving component 2 mounted on the frame 1, a Y-axis moving component 3 mounted on the X-axis moving component 2, a Z-axis moving component 4 mounted on the Y-axis moving component 3, and a labeling component 5 mounted on the Z-axis moving component 4. A printer 6 is mounted on the frame 1 for producing label paper. A conveyor track 7 is also mounted on the frame 1 for receiving and transporting workpieces. A positioning camera 8 is mounted on the frame 1 corresponding to the conveyor track 7. Both the labeling component 5 and the positioning camera 8 are electrically connected to a control system. The control system processes and analyzes the workpiece image information collected by the positioning camera 8, and then precisely controls the movement of the labeling component 5, the X-axis moving component 2, the Y-axis moving component 3, and the Z-axis moving component 4 to achieve accurate picking up of the label paper and affixing it to the workpiece.

[0029] Among them, reference Figure 2, X-axis moving assembly 2 includes a first slide rail 21 mounted on the rack 1 (arranged along the X-axis direction), and a first sliding block 22 is mounted on the first slide rail 21 and can slide smoothly. The first sliding block 22 is connected with a first driving member 23 (such as a motor and a screw nut pair combination or a linear motor, etc.). In operation, the first driving member 23 drives the first sliding block 22 to slide on the first slide rail 21 according to the instruction of the control system, thereby driving the Y-axis moving assembly 3 and the subsequent components mounted on the first sliding block 22 to move in the X-axis direction, and realizing the position adjustment of the labeling assembly 5 in the horizontal transverse direction (X-axis).

[0030] The Y-axis moving assembly 3 is located on the first sliding block 22 of the X-axis moving assembly 2, and includes a second slide rail 31 arranged along the Y-axis direction, and a second sliding block 32 is arranged on the second slide rail 31. The second sliding block 32 is connected with a second driving member 33 (which can also be driven by a motor and a screw nut pair, etc.). When it is necessary to adjust the labeling position in the Y-axis direction, the second driving member 33 drives the second sliding block 32 to slide on the second slide rail 31, thereby driving the Z-axis moving assembly 4 and the labeling assembly 5 to move in the Y-axis direction, and cooperating with the X-axis moving assembly 2 to realize positioning at any position in the plane.

[0031] The Z-axis moving assembly 4 is arranged on the second sliding block 32 of the Y-axis moving assembly 3, and is composed of a third slide rail 41 arranged along the Z-axis direction, a third sliding block 42 and a third driving member 43. The third driving member 43 (such as a suitable electric push rod or a lifting mechanism driven by a motor) drives the third sliding block 42 to slide on the third slide rail 41, thereby realizing the height adjustment of the labeling assembly 5 in the vertical direction (Z-axis) to adapt to the labeling requirements of workpieces of different heights.

[0032] Referring to Figures 2-3 The labeling assembly 5 is located on the third sliding block 42 of the Z-axis moving assembly 4, and includes a fourth slide rail 51 arranged along a certain direction (such as X-axis, Y-axis or Z-axis), and a fourth sliding block 52 is mounted on the fourth slide rail 51. The fourth sliding block 52 is connected with a fourth driving member 53 (which can be driven by a small motor or an air cylinder, etc.), and the fourth driving member 53 drives the fourth sliding block 52 to slide on the fourth slide rail 51, thereby realizing the fine position adjustment of the pneumatic suction head 54 in a small range. The pneumatic suction head 54 is connected with a gas source through a gas pipe. When picking up the label paper, the gas source provides negative pressure to make the pneumatic suction head 54 generate suction force, so as to accurately pick up the label paper produced by the printer 6 and placed on the label paper holder 9; when the labeling position is reached, the gas source changes the pressure or stops supplying gas, so that the pneumatic suction head 54 releases the label paper, and the label is accurately attached to the workpiece.

[0033] Referring to Figure 1The printer 6 is installed at a suitable position of the rack 1, and its internal structure adopts the existing mature label printing technology, and can produce label paper according to the preset label content and format. A label paper holder 9 is arranged at the paper outlet of the printer 6, and the label paper holder 9 can be made of a material with certain friction, such as rubber or textured plastic, to ensure that the label paper can be smoothly placed on the holder after being output from the printer 6, waiting for the pickup of the pneumatic suction head 54, avoiding problems such as paper jam and deviation during the paper output process.

[0034] The conveying track 7 is installed on the rack 1, and its surface is smooth and has certain friction, so that the workpiece can move smoothly on the track. The width and length of the conveying track 7 are designed according to the size of the workpiece and the production process requirements in actual production. One or more alignment cameras 8 are installed at a suitable position of the top of the rack 1 (the number and layout are determined according to the actual positioning accuracy and field of view range requirements), and the alignment camera 8 is connected to the control system through a data line, and the workpiece image captured by the alignment camera 8 is transmitted to the control system in real time. The combination of multiple alignment cameras 8 can realize a wider illumination range, and ensure that the shape, size, surface features and position information of the workpiece are captured comprehensively from different angles. The alignment camera 8 adopts a high-resolution CCD camera, which can clearly and accurately obtain the shape, size, surface features and position information of the workpiece, and provide a basis for the accurate positioning of the subsequent labeling assembly 5. The alignment camera 8 can accurately obtain the position information of the workpiece, has a large illumination range, can comprehensively cover the workpiece and the surrounding area on the conveying track 7, and cooperates with each component to realize ultra-high-precision automatic positioning and labeling operation.

[0035] The mounting bracket 10 is installed on the rack 1 near the alignment camera 8, and has a structure that is firm and has certain adjustability, so as to ensure that the face lamp 11 can accurately irradiate the labeling area. The face lamp 11 is installed on the mounting bracket 10, and the face lamp 11 can select an LED surface light source, which has uniform light emission and adjustable brightness, and provides sufficient illumination for the labeling area. An avoiding through hole 12 is formed in the face lamp 11, and the position and size of the avoiding through hole 12 match the lens position and field of view range of the alignment camera 8, so as to ensure that the face lamp 11 can provide illumination without causing any obstruction to the shooting of the alignment camera 8, and ensure that the alignment camera 8 can accurately obtain the image information of the workpiece and the label. The mounting bracket 10 provides a stable mounting position for the face lamp 11, the face lamp 11 can provide sufficient and uniform illumination for the labeling area, further expand the illumination range of the alignment camera 8, especially in some dark working environment or in the case of needing to clearly identify the details of the workpiece surface and the characteristics of the label, the combination of good illumination and wide CCD illumination range can help the alignment camera 8 to more accurately obtain the image information of the workpiece and the label.

[0036] The implementation principle of the embodiment of the present application is as follows: in actual use, first, the workpiece to be labeled is placed on the conveying track 7, and the conveying track 7 transports the workpiece to the labeling area. The conveying track 7 stops the movement of the workpiece, the alignment camera 8 shoots the image of the workpiece in real time and transmits it to the control system, and the control system calculates the position and attitude of the workpiece according to the image information. At the same time, the printer 6 produces label paper according to the preset information and places it on the label paper holder 9. Then, the X-axis moving assembly 2, the Y-axis moving assembly 3 and the Z-axis moving assembly 4 act in coordination according to the instruction of the control system, move the pneumatic suction head 54 of the labeling assembly 5 above the label paper holder 9, and the pneumatic suction head 54 picks up the label paper. Next, the shaft moving assemblies accurately move the pneumatic suction head 54 with the label paper to the specified labeling position of the workpiece according to the calculation results again, and the pneumatic suction head 54 releases the label paper to complete the labeling. The conveying track 7 continues to start the movement of the workpiece, and the workpiece continues to be transported, and the whole process is repeated to realize the full-automatic and high-precision positioning and labeling operation.
