Description

Technical Field

[0001] The present invention relates to the technical field of clothing manufacturing, and particularly to a clothing label recognition device and a sewing machine. Background Art

[0002] In the clothing industry, clothing labels, also known as tags or hangtags, are information carriers attached to clothes. They usually contain important information about the product, such as brand name, size, material, washing instructions, and unique product identification, which are crucial for both consumers and brands.

[0003] In the prior art, the connection between the clothing label and the clothes mainly relies on a series of manual operations. First, it is necessary to manually distinguish the front and back directions of the clothing label and ensure that the relevant information on the clothing label, such as the logo, is accurate. Then, the clothing label is placed at a specific position on the clothes. Next, by operating the sewing machine, the clothing label is sewn and fixed on the clothes. Finally, it is still necessary to rely on manual inspection of the sewn clothing label to check whether there are problems such as incorrect clothing label information or reversed front and back.

[0004] However, when manually placing the clothing label, situations such as incorrect placement direction, reversed front and back, or incorrect logo on the clothing label often occur. Moreover, these errors are difficult to be detected in a timely manner during the operation process, resulting in an increased difficulty in subsequent quality inspection work. In addition, due to completely relying on manual visual recognition of whether the clothing label is placed correctly, working for a long time is prone to fatigue, making the error rate remain high, seriously affecting the production efficiency and product quality, and increasing the production cost. Summary of the Invention

[0005] The purpose of the present invention is to provide a clothing label recognition device and a sewing machine to solve the technical problems of low efficiency and high error rate in manually recognizing clothing labels in the prior art.

[0035] Embodiment 1

[0036] The embodiment of the present invention provides a clothing label recognition device, which can automatically recognize whether relevant information on the clothing label, such as the logo, is correct during the sewing process of the clothing label, and promptly prompt the operator.

[0037] See Figures 1 to 6 , the clothing label recognition device provided by the embodiment of the present invention includes a workbench 1 and a recognition component 2. Among them, the workbench 1 is used to place clothes and labels; the recognition component 2 is connected to the workbench 1, and the recognition component 2 includes an adjustment mechanism 21 and a monitoring probe 22. The adjustment mechanism 21 is connected to the monitoring probe 22 and is used to adjust the angle and position of the monitoring probe 22; the monitoring probe 22 is used to recognize the display information of the label located on the workbench 1 and determine whether the display information conforms to the preset information content. If not, a prompt information is generated.

[0038] The clothing label recognition device proposed by the present invention provides a stable placement platform for clothes and labels by setting the workbench 1, ensuring the stability of the label during the recognition process and creating a basic condition for accurate recognition. The adjustment mechanism 21 can flexibly adjust the angle and position of the monitoring probe 22, enabling it to comprehensively and accurately obtain the display information of the label on the workbench 1, improving the flexibility and adaptability of recognition, and meeting the detection requirements of different sizes of labels, special-shaped labels, and curved sewing positions. The monitoring probe 22 can automatically recognize the display information of the label and compare it with the preset information content. Once a non-conforming situation is found, a prompt information is immediately generated, allowing the operator to quickly know the problem and make adjustments and corrections in a timely manner. Through the linkage design of the monitoring probe 22 and the adjustment mechanism 21, this clothing label recognition device realizes the automatic recognition and direction determination of the label display information, replaces the manual visual identification operation mode, can continuously, stably, and accurately perform recognition, avoids problems such as misjudgment and inefficiency during the manual visual recognition process, and effectively improves the production efficiency.

[0039] This embodiment is based on the recognition requirements during the clothing label sewing process in the clothing production link. Of course, this device is not limited to this application scenario and also has good applicability in other fields involving clothing label and tag recognition.

[0040] The clothing label recognition device of the present invention will be described in detail below from aspects such as the specific operations of each component of the device, the mutual cooperation relationship, and the achieved effects, so that those skilled in the art can better understand and implement the present invention.

[0041] In this embodiment, the workbench 1 serves as the basic bearing component of the entire clothing label recognition device. Its structural design closely revolves around the functional requirements of placing clothes and clothing labels, while also taking into account stability, convenience, and the ability to cooperate with other components.

[0042] The workbench 1 is generally rectangular in shape. The top of the workbench 1 is used to place clothes, clothing labels, and for installing the clothing label recognition device. A moving mechanism is provided at the bottom of the workbench 1, and the moving mechanism can drive the workbench 1 to move on a horizontal plane, thereby improving the flexibility of the workbench 1 and enabling the workbench 1 to flexibly adjust its position on the horizontal plane according to the layout of the production site and the needs of the work process.

[0043] Specifically, side plates 11 are symmetrically installed on both sides of the bottom of the workbench 1. A bottom plate 12 is provided at the bottom corresponding to each side plate 11. The two bottom plates 12 are respectively parallel to the two wide sides of the workbench 1. A self-locking universal wheel 14 is connected to each end of each bottom plate 12. The self-locking universal wheels 14 enable the workbench 1 to move flexibly within the working area, facilitating the operator to adjust the position of the workbench 1 at any time according to the actual needs of the production process. When it is necessary to fix the workbench 1 for clothing label recognition operations, the self-locking universal wheels 14 can be locked through simple operations, and the workbench 1 can be firmly fixed at the designated position to avoid interfering with the recognition result due to the movement of the workbench 1 during the recognition process.

[0044] In addition, a cross plate 13 is fixedly connected between the two bottom plates 12. The cross plate 13 further enhances the stability of the bottom structure of the workbench 1 and improves the anti-overturning ability of the overall device.

[0045] Preferably, a start switch 15 is provided on the workbench 1. The start switch 15 is electrically connected to the monitoring probe 22, so that by pressing the start switch 15, the monitoring probe 22 can be controlled to start or stop.

[0046] Preferably, a control box 16 is provided on the workbench 1. Control elements such as a PLC and a relay are integrated inside the control box 16. The control box 16 is electrically connected to the monitoring probe 22 in the recognition component 2 through a data cable sleeved with a protective wire tube. The protective wire tube effectively protects the data cable from interference and damage by external environmental factors, ensuring the stability and reliability of data transmission. The control box 16 is responsible for receiving the clothing label image data collected by the monitoring probe 22, and accurately analyzing and processing the data according to preset programs and algorithms, thereby realizing the comprehensive monitoring and intelligent control of the clothing label recognition process. Among them, the monitoring probe 22 selects an existing CCD camera. Components such as the CCD camera, PLC, and relay are all common devices in this field, and their working principles and specific structures are not elaborated here.

[0047] The clothes label recognition device further includes a warning light 17 and a display screen 18. When the monitoring probe 22 recognizes that the display information of the clothes label does not conform to the preset information content, the control box 16 will quickly issue an instruction to make the warning light 17 start the flashing mode. This attracts the attention of the operator, ensures that the operator can promptly detect the problems existing in the clothes label, so as to take corresponding measures for processing, effectively avoiding unnecessary subsequent processing operations and reducing production costs.

[0048] The display screen 18 is installed on the workbench 1 and is fixedly supported by a column 19. The display screen 18 is electrically connected to the control box 16 and is used to display in real time the clothes label image information collected by the monitoring probe 22 and the recognition processing results. During the clothes label recognition process, the operator can directly observe the detailed images of the clothes label from the display screen 18. When the display information of the clothes label does not conform to the preset content, the warning light 17 is used to remind the operator, and the display screen 18 is used to display the specific error types, such as the front and back error of the clothes label, logo error, key text information error, etc., providing intuitive and detailed information for the operator to facilitate the operator to quickly judge and handle problems. In addition, the display screen 18 also has certain storage and historical record query functions. The operator can retrieve the clothes label information recognized in the past, which is convenient for production data statistics and quality analysis, and helps to optimize the production process and improve the product quality control level.

[0049] Among them, the display information includes: brand name, product model, size specification, etc., which can be adaptively adjusted according to actual needs during the actual operation process and are not limited here.

[0050] The adjustment mechanism 21 is used to flexibly adjust the angle and position of the monitoring probe 22 to improve the adaptability and versatility of the device. Specifically, refer to Figure 3 and Figure 4The adjustment mechanism 21 includes a first screw rod 211, a moving block 212 and a driving unit 213. The moving block 212 is sleeved on the first screw rod 211 and is threadedly connected to the first screw rod 211 through a ball nut. The monitoring probe 22 is connected to the moving block 212. The driving unit 213 is arranged at one end of the first screw rod 211, and is used to drive the first screw rod 211 to rotate around its own axis, thereby driving the moving block 212 to move along the axial direction of the first screw rod 211. The driving unit 213 uses a servo motor. When the position of the monitoring probe 22 needs to be adjusted, a control command is sent to the servo motor through the control box 16, and the servo motor outputs a corresponding torque according to the command to drive the first screw rod 211 to rotate. As the first screw rod 211 rotates, the moving block 212 threadably connected thereto will make a linear motion along the axial direction of the first screw rod 211 according to the pitch of the first screw rod 211, thereby driving the monitoring probe 22 connected to the moving block 212 to move synchronously. By precisely controlling the rotation direction, speed and number of rotations of the servo motor, the moving direction, speed and displacement of the moving block 212 can be precisely controlled, thereby achieving precise adjustment of the position of the monitoring probe 22.

[0051] More specifically, the adjustment mechanism 21 includes a main board 215 and two ribs 216 connected to the main board 215 and arranged opposite to each other. The three are arranged in a U shape, and the first screw rod 211 passes through the two ribs 216 in sequence.

[0052] Preferably, the adjustment mechanism 21 also includes a guide rod 214, two guide rods 214 are provided, and the two guide rods 214 are symmetrically arranged on both sides of the first screw rod 211, and the guide rods 214 are passed through the moving block 212 and are slidably connected with the moving block 212. The guide rod 214 provides precise guidance for the movement of the moving block 212. When the driving part 213 drives the first screw rod 211 to rotate, so that the moving block 212 moves along the axial direction of the first screw rod 211, the guide rod 214 can strictly limit the moving block 212 to move only in a direction parallel to the first screw rod 211, thereby avoiding the moving block 212 from deflecting or shaking during the movement. At the same time, the guide rod 214 shares part of the weight of the moving block 212 and the monitoring probe 22 during the movement, so that the force of the entire adjustment mechanism 21 is more uniform and reasonable.

[0053] Further, the adjustment mechanism 21 further includes a positioning shaft 217, a sliding sleeve 218, and a locking structure 220. One end of the positioning shaft 217 is fixedly connected to the moving block 212. The positioning shaft 217 extends in a direction perpendicular to the first lead screw 211. The sliding sleeve 218 is sleeved and slidably connected to the positioning shaft 217. The monitoring probe 22 is connected to the sliding sleeve 218. The sliding sleeve 218 can rotate around the positioning shaft 217 and move along the positioning shaft 217. The locking structure 220 can limit the rotation and movement of the sliding sleeve 218 relative to the positioning shaft 217. The cooperation between the sliding sleeve 218 and the positioning shaft 217 provides more adjustment directions for the monitoring probe 22. By rotating and moving the sliding sleeve 218 along the positioning shaft 217, the activity range of the monitoring probe 22 is further expanded, enabling it to more accurately align with a specific position on the clothing label for identification, and being able to obtain more comprehensive and accurate display information of the clothing label, reducing the recognition error caused by inappropriate angles and positions. When the monitoring probe 22 is adjusted to an ideal position and angle through the rotation and movement of the sliding sleeve 218, the locking structure 220 can limit the movement and rotation of the sliding sleeve 218 relative to the positioning shaft 217, ensuring that the monitoring probe 22 remains stable during operation without accidental displacement or angle change, thereby guaranteeing the accuracy and stability of the recognition result.

[0054] Specifically, an opening is formed along the axial direction of the sliding sleeve 218 itself. Fixed plates 219 are respectively fixedly connected to both sides of the opening. The two fixed plates 219 are arranged oppositely. The locking structure 220 includes a fixed rod 2201, a screw rod 2202, and a pressing block 2203. One end of the fixed rod 2201 is connected to the monitoring probe 22. The screw rod 2202 sequentially passes through the two fixed plates 219 and is threadedly connected to the other end of the fixed rod 2201. The pressing block 2203 is sleeved on the screw rod 2202 and is threadedly connected to the screw rod 2202. The screw rod 2202 can rotate around its own axis, driving the pressing block 2203 to move along the axial direction of the screw rod 2202, thereby squeezing or moving away from one of the fixed plates 219 to adjust the size of the opening to lock or unlock the sliding sleeve 218. When it is necessary to lock the sliding sleeve 218, rotate the screw rod 2202 to make it rotate around its own axis. Due to the threaded fit between the screw rod 2202 and the pressing block 2203, the pressing block 2203 will move along the axial direction of the screw rod 2202 and gradually squeeze one of the fixed plates 219. As the pressing block 2203 squeezes, the opening will become smaller, thereby locking the sliding sleeve 218 and restricting its movement and rotation relative to the positioning shaft 217. When it is necessary to unlock the sliding sleeve 218, rotate the screw rod 2202 in the reverse direction, driving the pressing block 2203 to move away from the fixed plate 219, the opening becomes larger, and the sliding sleeve 218 returns to the state of being movable and rotatable.

[0055] Preferably, a connecting rod 221 is fixedly installed at the end of the fixed rod 2201 away from the screw rod 2202. A U-shaped plate 222 is fixedly connected to the bottom of the connecting rod 221. The bottom of the U-shaped plate 222 is fixedly connected to the top of the detection probe.

[0056] Preferably, in order to facilitate the operator to drive the screw 2202 to rotate, a handle 2204 is provided at one end of the screw 2202 away from the fixed rod 2201, which is convenient for the operator to hold and apply force.

[0057] During the actual use process, the lens of the monitoring probe 22 is easily contaminated by sundries such as dust and fibers, which will affect its imaging quality and recognition accuracy. Therefore, referring to Figure 5 and Figure 6 , the clothing label recognition device further includes a cleaning component 3. The cleaning component 3 is connected to the monitoring probe 22. The cleaning component 3 includes a power mechanism 31 and a cleaning brush 32. The power mechanism 31 can drive the cleaning brush 32 to move on the lens of the monitoring probe 22, thereby cleaning the lens of the monitoring probe 22 and avoiding problems such as blurred images and inaccurate information caused by lens contamination.

[0058] Specifically, the power mechanism 31 includes a second lead screw 311, a movable block 312, and a power unit 313. The movable block 312 is sleeved on the second lead screw 311 and is threadedly connected to the second lead screw 311. The cleaning brush 32 is connected to the movable block 312. The power unit 313 is used to drive the second lead screw 311 to rotate around its own axis, thereby driving the movable block 312 to move along the axial direction of the second lead screw 311. Through the lead screw drive method, precise linear motion control can be achieved, ensuring that the cleaning brush 32 can accurately perform covering cleaning on the lens of the monitoring probe 22, improving the comprehensiveness and accuracy of cleaning. Secondly, the lead screw drive has good stability and reliability, which can ensure the smoothness of the cleaning brush 32 during movement, avoid jitter or jumping, and thus effectively prevent accidental damage to the lens.

[0059] In other embodiments, the power mechanism 31 can also select devices such as cylinders and telescopic motors to drive the cleaning brush 32 to move, which will not be elaborated here.

[0060] Among them, the cleaning component 3 includes two mounting boxes 314 fixedly installed at the bottom on both sides of the monitoring probe 22. A limiting groove 3141 is penetrated and provided at the bottom of each mounting box 314. A second lead screw 311 is rotatably connected inside each mounting box 314. The movable block 312 is threadedly connected to the second lead screw 311 through a ball nut. The movable block 312 is slidably connected inside the mounting box 314. A transfer rod 33 is fixedly connected to the bottom of both movable blocks 312. After the bottoms of the two transfer rods 33 pass through the bottom of the limiting groove 3141, a bearing plate 34 is commonly installed. A cleaning brush 32 for cleaning the lens of the monitoring probe 22 is fixedly connected to the center of the top of the bearing plate 34.

[0061] Furthermore, two sets of power mechanisms 31 are provided, and the two sets of power mechanisms 31 are symmetrically arranged on both sides of the monitoring probe 22. One set of power mechanism 31 is connected to each side of the cleaning brush 32, so as to provide uniform and balanced driving force from both sides of the cleaning brush 32, making the cleaning brush 32 move more smoothly during the movement.

[0062] Furthermore, in order to ensure the synchronous movement between the two sets of power mechanisms 31, the two sets of power mechanisms 31 share a power unit 313. Specifically, the power unit 313 is a micro motor. The output end of the micro motor is fixedly sleeved with a driving pulley 315. One end of each second lead screw 311 penetrates through the mounting box 314 and is coaxially and fixedly connected to a connecting shaft 318. A driven pulley 316 is fixedly sleeved at the end of the connecting shaft 318 away from the second lead screw 311. A toothed belt 317 is commonly engaged between the driven pulley 316 and the driving pulley 315. Thus, through the toothed belt 317, one driving pulley 315 can drive the two driven pulleys 316 to move simultaneously. When the micro motor is started, its output end drives the driving pulley 315 to rotate. Since the toothed belt 317 engages with the driving pulley 315 and the two driven pulleys 316 at the same time, the rotation of the driving pulley 315 is transmitted to the two driven pulleys 316 through the toothed belt 317, enabling the two driven pulleys 316 to rotate synchronously. Since the driven pulley 316 and the second lead screw 311 are fixedly connected through the connecting shaft 318, the rotation of the driven pulley 316 drives the second lead screw 311 to rotate synchronously, so as to drive the movable block 312 connected to the second lead screw 311 to drive the cleaning brush 32 to move synchronously, thereby causing frictional contact between the cleaning brush 32 and the lens of the monitoring probe 22, and achieving the cleaning effect on the lens of the monitoring probe 22.

[0063] The following specifically describes the usage process of the clothes tag recognition device provided in this embodiment.

[0064] When using this clothes tag recognition device, first, place the clothes with the tag to be recognized flat on the specific area at the top of the workbench 1. Since the workbench 1 is equipped with self-locking universal wheels 14 at the bottom, the workbench 1 can be pushed to a suitable position according to the actual layout of the operation area and the specific requirements of the work process. After the position is determined, operate the locking device on the self-locking universal wheels 14 to firmly fix the workbench 1 to prevent the workbench 1 from moving during subsequent operations and affecting the recognition effect.

[0065] Next, press the start switch 15 on the workbench 1 to start the monitoring probe 22. At this time, the control box 16 starts to work. The control elements such as the PLC and the relay inside the control box 16 receive the clothes tag image data collected by the monitoring probe 22 through the data connection line sleeved with a protective wire tube, and process and analyze it according to the preset programs and algorithms.

[0066] Then, adjust the angle and position of the monitoring probe 22 according to actual needs. By controlling the operation of the servo motor, the first lead screw 211 is driven to rotate. As the first lead screw 211 rotates, the moving block 212 sleeved on it moves along the axial direction of the first lead screw 211, thereby driving the monitoring probe 22 to move to a suitable position in the horizontal direction. During the movement of the moving block 212, the guiding rods 214 on both sides ensure the stability and accuracy of its movement, preventing the moving block 212 from shifting or shaking. Moreover, the operator reversely rotates the handle 2204, driving the screw 2202 to rotate, driving the pressing block 2203 away from the fixed plate 219, the opening becomes larger, and the sliding sleeve 218 returns to the state of being movable and rotatable. The operator rotates the sliding sleeve 218 around the positioning shaft 217 or moves it along the positioning shaft 217. After finding the most ideal recognition angle and position, the operator rotates the handle 2204, driving the screw 2202 to rotate, driving the pressing block 2203 to approach and squeeze the fixed plate 219, the opening becomes smaller, and the sliding sleeve 218 is locked and fixed to ensure the stability of the monitoring probe 22 during the recognition process.

[0067] During the recognition operation, the monitoring probe 22 collects information from the clothing label, and then transmits the collected information such as brand name, product model, size specification, etc. to the control box 16. The control box 16 analyzes and compares this information. If it is found that the information displayed on the clothing label does not match the preset content, it will immediately control the warning light 17 to flash to attract the attention of the operator, and at the same time display the specific error type on the display screen 18, such as clothing label front-back error, logo error, key text information error, etc.

[0068] To ensure that the lens of the monitoring probe 22 always remains clear and avoid affecting the recognition accuracy due to lens contamination, the cleaning component 3 is started. The micro motor in the cleaning component 3 starts to operate, and the driving pulley 315 at its output end drives two driven pulleys 316 to rotate simultaneously through the toothed belt 317. The rotation of the driven pulley 316 drives the second lead screw 311 connected to it to rotate, causing the moving block 312 sleeved on the second lead screw 311 to move along the axial direction of the lead screw. The moving block 312 drives the cleaning brush 32 to move on the surface of the lens of the monitoring probe 22, thereby realizing the cleaning of the lens.

[0069] During the entire recognition process, the operator can observe the detailed images of the clothing label and the recognition processing results in real time through the display screen 18, and can also query the information of the previously recognized clothing labels, so as to conduct statistical analysis of production data and quality analysis, providing a basis for optimizing the production process and improving the product quality control level.
