Description

Technical Field

[0001] This invention relates to the field of garment manufacturing technology, and in particular to a fabric sewing inspection tool. Background Technology

[0002] With the continuous development of the garment industry, clothing has become increasingly exquisite. Garments, home textiles, and other items are all made by piecing together pieces of fabric using sewing machines. In the garment-making process, sewing thread is not only an important accessory but also serves a decorative function. The quality of the sewing affects the quality and appearance of the finished product.

[0003] The current method for inspecting fabric stitching involves using light to see through the fabric and repeatedly stretching it manually at different locations to check if the stitching meets the standards. This method has the following drawbacks: a small inspectable area per test, low inspection efficiency, a high rate of missed inspections, and the possibility of the fabric being too tight or too loose due to different inspectors, stretching times, and manual stretching forces. Summary of the Invention

[0004] Therefore, a fabric seam inspection tool is needed to solve the problems of small single-inspection range, low inspection efficiency, high missed inspection rate, and excessive or insufficient fabric tension caused by different inspectors, different stretching times, and different manual stretching forces.

[0005] To achieve the above objectives, this application provides a fabric seam inspection tool, comprising:

[0006] Base, including support plate;

[0007] The lifting mechanism includes a fixed component, a sliding component, and a driving component. The fixed component is disposed on the support plate. The sliding component can move along the fixed component in the height direction. The driving component is disposed on the sliding component and is used to drive the sliding component to move in the height direction of the fixed component.

[0008] The external support mechanism includes an external support plate, a lower connecting rod, a middle connecting rod, and an upper connecting rod. The inner end of the lower connecting rod is hinged to the sliding member, the outer end of the lower connecting rod is hinged to the middle connecting rod, the inner end of the middle connecting rod is hinged to the fixing member, the outer end of the middle connecting rod is hinged to the inner side of the external support plate, the inner end of the upper connecting rod is hinged to the fixing member, and the outer end of the upper connecting rod is hinged to the inner side of the external support plate.

[0009] Furthermore: the driving component includes a pedal, the support plate is provided with a through hole for connecting the pedal and the sliding component, the pedal is disposed on the sliding component and located below the support plate, and the pedal is configured to drive the sliding component to move in the height direction of the fixed component under the action of an external force.

[0010] Furthermore, it also includes a rotating component, through which the fixing component is mounted on the support plate.

[0011] Furthermore: the rotating component includes a bearing.

[0012] Furthermore, the top of the pedal is connected to the slider by a pull rope.

[0013] Furthermore, the distance between the pedal and the slider can be adjusted by the pull cord.

[0014] Further: the sliding member includes a sliding groove and a movable sleeve. The sliding groove is disposed on the fixed member and extends along the height direction of the fixed member. The movable sleeve is slidably sleeved on the fixed member. The inner wall of the movable sleeve is provided with a slider that is slidably connected to the sliding groove.

[0015] Furthermore, it also includes an elastic element disposed on the slider and the support plate, for resetting the slider.

[0016] Furthermore, it also includes a light strip, which is disposed on the fixing member or the outer support piece.

[0017] Furthermore: one of the outer support plates, one of the lower connecting rods, one of the middle connecting rods, and one of the upper connecting rods form one set of outer support devices, and there are four sets of outer support devices, which are evenly distributed along the circumference of the fixing member.

[0018] Unlike existing technologies, in the above technical solution, the quality inspector uses a drive component to pull the sliding component downwards along the height of the fixed component. The inner end of the lower connecting rod also moves downwards with the sliding component, causing the middle and upper connecting rods to rotate. The outer support plate expands outwards, thus stretching the cylindrical fabric fitted on the outside of the outer support plate. Conversely, when the drive component moves upwards, the outer support plate contracts inwards. In this way, the quality inspector can effectively control the tension of the fabric, overcoming the problems of small single-inspection range, low inspection efficiency, high missed inspection rate, and excessive or insufficient fabric tension caused by different quality inspectors, different stretching times, and different manual stretching forces. This improves the efficiency of seam inspection and is also convenient to operate. Attached Figure Description

[0045] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0046] Please see Figures 1 to 5 This embodiment provides a fabric seam inspection tool, comprising:

[0047] Base 1, including support plate 11;

[0048] The lifting mechanism 2 includes a fixing member 21, a sliding member 22 and a driving member. The fixing member 21 is disposed on the support plate 11. The sliding member 22 can move along the fixing member 21 in the height direction. The driving member is disposed on the sliding member and is used to drive the sliding member 22 to move in the height direction of the fixing member 21.

[0049] The external support mechanism 3 includes an external support plate 31, a lower connecting rod 32, a middle connecting rod 33, and an upper connecting rod 34. The inner end of the lower connecting rod 32 is hinged to the sliding member 22, the outer end of the lower connecting rod 32 is hinged to the middle connecting rod 33, the inner end of the middle connecting rod 33 is hinged to the fixing member 21, and the outer end of the middle connecting rod 33 is hinged to the inner side of the external support plate 31. The inner end of the upper connecting rod 34 is hinged to the fixing member 21, and the outer end of the upper connecting rod 34 is hinged to the inner side of the external support plate 31.

[0050] Unlike existing technologies, in the above technical solution, the quality inspector uses a drive component to pull the sliding component downwards along the height of the fixed component. The inner end of the lower connecting rod also moves downwards with the sliding component, causing the middle and upper connecting rods to rotate. The outer support plate expands outwards, thus stretching the cylindrical fabric fitted on the outside of the outer support plate. Conversely, when the drive component moves upwards, the outer support plate contracts inwards. In this way, the quality inspector can effectively control the tension of the fabric, overcoming the problems of small single-inspection range, low inspection efficiency, high missed inspection rate, and excessive or insufficient fabric tension caused by different quality inspectors, different stretching times, and different manual stretching forces. This improves the efficiency of seam inspection and is also convenient to operate.

[0051] Please see Figure 1 and Figure 4 According to a preferred embodiment of this application, the driving component includes a pedal 23, which is disposed on the sliding member and located below the support plate 11. The support plate 11 has a through hole for connecting the pedal 23 and the sliding member 22. The pedal 23 is configured to drive the sliding member 22 to move in the height direction of the fixed member 21 under the action of an external force. The quality inspector can use both hands and feet to apply downward force to the pedal 23, causing the pedal 23 to pull the sliding member 22 downward in the height direction of the fixed member 21. The inner end of the lower connecting rod 32 also moves downward with the sliding member 22, thereby causing the middle connecting rod 33 and the upper connecting rod 34 to rotate. The outer support plate 31 expands outward, thereby opening the cylindrical fabric sleeved on the outer side of the outer support plate 31.

[0052] In some embodiments, the driving component includes a pneumatic cylinder or a hydraulic cylinder. A pneumatic cylinder is a cylindrical metal component that guides a piston to perform linear reciprocating motion within the cylinder. Air in the cylinder expands, converting thermal energy into mechanical energy. A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, performing linear reciprocating motion (or oscillating motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, a reduction gear can be eliminated, and there is no transmission backlash, resulting in smooth movement. Taking a pneumatic cylinder as an example, a pneumatic cylinder includes a cylinder body and a piston rod. A reciprocating piston is disposed within the cylinder body, and a piston rod is disposed on the piston, extending through the cylinder body. Under the action of hydraulic oil, the piston rod can be controlled to perform linear reciprocating motion on the cylinder body. The pneumatic cylinder is positioned along the height direction of the fixing member 21, that is, the cylinder body is fixed to the fixing member 21. The inner end of the lower connecting rod 32 is hinged to the piston rod, and the movement of the piston rod drives the lower connecting member to rotate.

[0053] In some other embodiments, the drive component includes a motor and a lead screw and nut assembly. The lower connector is connected to the motor via the lead screw and nut assembly. When the output shaft of the motor rotates, the lead screw and nut assembly converts the rotational motion into linear motion, thereby driving the lower connector to rotate.

[0054] The advantages of using a cylinder to drive the external support mechanism 3 are that it is labor-saving, allowing the inspector to focus on the fabric seams. The disadvantages are that the pneumatic structure has a certain impact force, improper stroke adjustment can damage the fabric, and the inspection station must be equipped with compressed air, increasing equipment costs. The advantages of using a motor and lead screw and nut assembly to drive the external support mechanism 3 are that it is labor-saving, the movement stroke is accurate, and the inspector can focus on the fabric seams. The disadvantages are that the structure is complex, the installation of the inspection fixture is relatively labor-intensive, and the manufacturing cost is high. The advantages of using a foot pedal 23 to drive the external support mechanism 3 are that the structure is simple, the movement stroke is adjustable, and the manufacturing cost is low; therefore, this method is the preferred embodiment.

[0055] Please see Figure 4 According to one embodiment of this application, the fabric sewing inspection fixture further includes a rotating member 4, and a fixing member 21 is mounted on the support plate 11 via the rotating member 4. The fixing member 21 can rotate freely on the horizontal plane, which facilitates the quality inspector to inspect the quality of the sewing from various parts. This overcomes the problem of excessive or insufficient tension of the fabric caused by different quality inspectors, different stretching times, and different manual stretching forces, and overcomes the problem of high missed inspection rate and low inspection efficiency caused by operator fatigue.

[0056] Please see Figure 4According to one embodiment of this application, the rotating component 4 includes a bearing. The bearing is an important component in modern mechanical equipment, and its main function is to support the fixed component 21, reduce its coefficient of friction during movement, and ensure its rotational accuracy. The fixed component 21 is mounted on the support plate 11 via the bearing. The bearing includes an inner ring and an outer ring, with the inner ring located above the through hole in the support plate 11, facilitating the passage of the fixed component 21, the pull rope 231, or the pedal 23.

[0057] Please see Figure 1 and Figure 4 According to one embodiment of this application, the top of the pedal 23 is connected to the slider 22 by a pull rope 231. The pull rope 231 is torsion-resistant, so that when the fixing member 21 rotates, the pedal 23 does not rotate, thus keeping the inspector's position fixed. Specifically, the slider 22 and the pedal 23 are provided with through holes. Since the slider 22 is located above the pedal 23, the upper part of the pull rope 231 is fixed with a hook and hangs in the through hole of the slider 22 through the hook. The lower part of the pull rope 231 passes through the through hole on the pedal 23 and is wound around it. The pull rope 231 has sufficient strength, is easy to install, and is inexpensive.

[0058] Preferably, the pull rope 231 is made of steel wire rope, which consists of steel wires and a core. It is first made by twisting multiple layers of steel wires into strands, and then, with the core as the center, a certain number of strands are twisted into a spiral shape. Steel wire rope has high strength, light weight, stable operation, is not easy to break suddenly, and is reliable in operation.

[0059] Please see Figure 1 and Figure 4 According to one embodiment of this application, different quality inspectors have different body characteristics. If the position of the pedal 23 is not adjustable, it will affect the quality inspector's experience in using the pedal 23. Therefore, the distance between the pedal 23 and the sliding member 22 can be adjusted by the pull rope 231. Different quality inspectors can adjust the pedal 23 according to their own body conditions. For example, taller quality inspectors can raise the height of the pedal 23, and shorter quality inspectors can lower the height of the pedal 23. By adjusting the length of the steel wire pull rope 231, the distance of the pedal 23 from the ground can be adjusted, thereby controlling the movement stroke of the moving sleeve 222, so that the unfolding diameter of the outer support plate is suitable for the tension of the cylindrical fabric.

[0060] The fabric seam inspection tool is ingeniously designed to suit different quality inspectors. It allows inspectors to effectively control the tension of the fabric, overcoming the problems of excessive or insufficient tension caused by different inspectors, different times, and different manual stretching forces. It also overcomes the problems of high missed inspection rate and low inspection efficiency caused by operator fatigue.

[0061] Please see Figure 1 , Figure 2 and Figure 4According to one embodiment of this application, the sliding member 22 includes a groove 221 and a movable sleeve 222. The groove 221 is disposed on the fixed member 21 and extends along the height direction of the fixed member 21. The movable sleeve 222 is slidably sleeved on the fixed member 21. The inner diameter of the movable sleeve 222 is slightly larger than the outer diameter of the fixed member 21, so that the movable sleeve 222 can move along the outer wall of the fixed member 21. A slider is provided on the inner wall of the movable sleeve 222, which is slidably connected to the groove 221. The slider cooperates with the groove 221 to make the sliding smoother.

[0062] In some embodiments, the way the slider and the groove 221 cooperate can be replaced by the way the pulley and the groove 221 cooperate, or the way the block slider and the groove 221 cooperate can be replaced by the way the steel ball and the groove 221 cooperate.

[0063] According to another embodiment of this application, the sliding member 22 is slidably sleeved on the fixing member 21, and the sliding member 22 and the fixing member 21 can form a telescopic rod. The sliding member 22 can be cylindrical or prismatic in shape. When the fixing member 21 is set on the support plate 11 by the rotating member 4, the sliding member 22 adopts a non-circular cross-section structure, so that the fixing member 21 can drive the sliding member 22 to rotate together when rotating. In this way, the fixing member 21 can rotate freely on the horizontal plane, which makes it convenient for quality inspectors to inspect the quality of the stitching from various parts, overcoming the problem of excessive or insufficient tension of the fabric caused by different manual stretching forces of different quality inspectors at different times, and overcoming the problem of high missed inspection rate and low inspection efficiency caused by easy operator fatigue.

[0064] Please see Figure 4 According to one embodiment of this application, a lower hanging plate 223 is provided on the movable sleeve 222. The lower hanging plate 223 has a portion disposed on the outer wall of the movable sleeve 222, and a lower connecting member is hinged to this portion. The lower connecting member is indirectly connected to the movable sleeve 222. The lower hanging plate 223 has a portion extending into the fixing member 21, and a hanging rod 224 is provided on this portion. A pull rope 231 is hung at the bottom of the hanging rod 224.

[0065] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 According to one embodiment of this application, the fabric stitching inspection fixture further includes an elastic element 5, which is disposed on the sliding member 22 and the support plate 11, and is used to reset the sliding member 22. The elastic element 5 includes a coil spring or a rubber spring, and its elastic direction is along the height direction of the fixing member 21. After the inspection is completed, the pedal 23 is released, the spring drives the moving sleeve 222 to rebound, and the lower connecting member, the middle connecting member and the upper connecting member rotate to the initial position, thereby causing the outer support plate 31 to retract inward, which facilitates the removal of the cylindrical fabric.

[0066] Please see Figure 1 , Figure 2 and Figure 4 According to one embodiment of this application, the fabric seam inspection fixture further includes a light strip 6, which is disposed on the fixing member 21 or the outer support plate 31. Taking the light strip 6 disposed on the fixing member 21 as an example, one end of the light strip 6 is located at the upper part of the fixing member 21, and the other end extends downward to the lower part of the fixing member 21. The light strip 6 can also be arranged in a circle around the outer wall of the fixing member 21, so that the light is diffused outward. The light strip 6 emits light, illuminating the fabric inside the cylindrical fabric, and the quality inspector touches the light from the outside to check whether the quality of the fabric complies with regulations. The light source of the light strip 6 is an LED (light-emitting diode), which is highly efficient and energy-saving, a cold light source, generates very little heat, and does not produce heat radiation.

[0067] Please see Figures 1 to 5 According to one embodiment of this application, an outer support plate 31, a lower connecting rod 32, a middle connecting rod 33, and an upper connecting rod 34 form a set of outer support devices. There are multiple sets of outer support devices, evenly distributed along the circumference of the fixing member. If there are two sets of outer support devices, the distance between adjacent sets is 180°, and the two sets are arranged opposite each other, distributed on the left and right sides of the fixing member 21; if there are three sets of outer support devices, the distance between adjacent sets is 120°; if there are four sets of outer support devices, the distance between adjacent sets is 90°.

[0068] Please see Figure 4 According to one embodiment of this application, the middle connector and the upper connector are respectively fixed to the fixing member 21 and the outer support plate 31 by the lifting lugs 7. The outer ends of the lower connectors 32 are respectively disposed on the middle lugs of the middle connectors 33, and the inner ends of the lower connectors 32 are disposed on the lower hanging plate 223 or the movable sleeve 222 by the lifting lugs 7. Specifically, two of the four lower connectors 32 are fixed to both ends of the lower hanging plate 223, and the remaining two of the four lower connectors 32 are fixed to the movable sleeve 222 by the lifting lugs 7.

[0069] According to one embodiment of this application, the base 1 further includes a tabletop and a plurality of legs disposed on the bottom of the tabletop. The tabletop stands on the ground via the legs, and a support plate 11 is disposed on the tabletop.

[0070] The working principle of this application is as follows:

[0071] By stepping on the foot pedal 23, the hanging rod 224 mounted on the lower hanging plate 223 is driven, causing the movable sleeve 222 connected to it to move downward along the slide groove 221 in the fixing member 21. This causes the lower connecting rod 32 to swing downward around the circular hole of the lifting lug 7, causing the outer support plate 31 to unfold outward, thus tightening the cylindrical fabric fitted on the outer support plate 31. Under the illumination of the four light strips 6 fixed to the fixing member 21, defects in the seam of the entire fabric are easily detected. The entire mechanism is fixed to the support plate 11 by bearings, and the quality of the seam of different parts of the fabric can be checked by rotation. After the inspection is completed, the foot pedal 23 is released, and the movable sleeve 222 rises upward under the action of the compression spring, and the outer support plate 31 retracts, so that the inspected fabric can be easily removed. By adjusting the length of the steel wire rope 231, the distance of the foot pedal 23 from the ground can be adjusted, thereby controlling the movement stroke of the movable sleeve 222, so that the opening diameter of the outer support plate assembly is suitable for the tension of the cylindrical fabric.

[0072] The beneficial effects of this application are as follows:

[0073] 1. Quality inspectors can effectively control the tension of the fabric, overcoming the problem of excessive or insufficient tension caused by different manual stretching forces applied by different inspectors at different times, and overcoming the problems of high missed inspection rate and low inspection efficiency caused by operator fatigue.

[0074] 2. The distance between the pedal 23 and the sliding part 22 can be adjusted by the pull rope 231. Different quality inspectors can adjust the pedal 23 according to their own physical condition. For example, taller quality inspectors can raise the height of the pedal 23, and shorter quality inspectors can lower the height of the pedal 23. By adjusting the length of the steel wire pull rope 231, the distance of the pedal 23 from the ground can be adjusted, thereby controlling the movement stroke of the moving sleeve 222, so that the unfolding diameter of the outer support plate is suitable for the tension of the cylindrical fabric.

[0075] 3. Using manual stretching of different parts multiple times, taking the inspection of trouser leg seams as an example, each pair of trousers requires 12 to 14 stretches of each leg, each stretch lasting about 3 seconds. Including the time for visual inspection of the seams, inspecting one pair of trousers takes 50 to 70 seconds, with a false negative rate of about 6%. However, with the fabric seam inspection tool of this application, manual stretching is not required. Each pair of trousers is loaded and unloaded twice (once for each leg), each loading and unloading taking 4 seconds. Including the time for visual inspection of the seams, inspecting one pair of trousers only takes 15 to 20 seconds, with a false negative rate of less than 1%.
