Description

Technical Field

[0001] This invention relates to the field of laser measuring instrument technology, specifically to a fabric flatness detection device with intelligent positioning function. Background Technology

[0002] During the production of textiles, especially those produced using splicing processes, it is necessary to conduct strength tests on the fabric joints to ensure the quality of the finished product. Additionally, laser measuring instruments are used to test the flatness of the textile. The core function of the laser measuring instrument is to acquire three-dimensional morphological data of the textile surface in real time through non-contact, high-precision laser scanning, accurately quantifying the degree and distribution of defects such as flatness, unevenness, and wrinkles.

[0003] However, when using laser measuring instruments to test the flatness of textiles, the fabric tension can fluctuate, causing some parts of the fabric to become loose, which affects the accuracy of the test. Furthermore, existing testing equipment, such as flatness testing equipment and interface strength testing equipment, are two separate devices that require separate testing of the fabric rolls. This testing method is not only inefficient but also expensive. Summary of the Invention

[0004] The purpose of this invention is to provide a textile fabric flatness detection device with intelligent positioning function to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a textile fabric flatness detection device with intelligent positioning function, comprising a support, an electric winding roller rotatably mounted on the support, a platform mounted on the support, crossbeams symmetrically mounted between the platforms, a pre-inspection auxiliary device mounted between the crossbeams, an intelligent robotic arm mounted on the platform, and a laser detector mounted on the intelligent robotic arm.

[0006] The flatness testing device is equipped with a control system that operates the entire device. Two sets of electric winding rollers are symmetrically arranged. The fabric is wound onto these rollers; one roller unwinds the fabric, and the other rewinds it. The fabric then passes through a pre-inspection auxiliary device. This device consists of two sets, each located on the side of one of the two stands.

[0007] Furthermore, the pre-inspection auxiliary device includes a drive unit and several pad assemblies. The pad assemblies are installed at one end of the frame, the drive unit is installed on the crossbeam, the crossbeam has a connecting end, a rotating rod is rotatably installed between the connecting ends, a tension detection assembly is installed on the rotating rod, and gears are installed at both ends of the rotating rod, the gears mesh with the drive unit for transmission.

[0008] Each set of pre-inspection auxiliary devices includes several pad assemblies and several tension detection assemblies. Several pad assemblies are arranged in a row and set on the side of the frame, and several tension detection assemblies are connected in series on the rotating rod.

[0009] Furthermore, the tension detection assembly includes a movable cylinder and an inner liner cylinder. A sliding ring is provided on the rotating rod, and a T-shaped rod is slidably installed on the sliding ring. The movable cylinder is connected to the bottom end of the T-shaped rod. A detector is installed on the rotating rod and connected to the movable cylinder. A detection roller is rotatably installed on the movable cylinder. A tension roller is rotatably installed on the inner liner cylinder. A rotary spring is installed between the tension roller and the inner liner cylinder. The inner liner cylinder is installed on the rotating rod.

[0010] Furthermore, the tensioning roller is provided with tensioning teeth, the bottom end of the tensioning roller is provided with an opening, the tensioning roller is provided with a transition end located at both ends of the opening, the tensioning roller is provided with a protrusion, and several arc-shaped rods are installed on the protrusion. The arc-shaped rods are slidably connected to the inner liner, and a rotary spring is installed between the protrusion and the inner liner.

[0011] The transition end is used to trim the open section to prevent excessive shearing force from damaging the textile when directly biting the textile through the section.

[0012] After the initial inspection of the interface is qualified, when the flatness of the textile tension is accurately tested, the control system moves the textile interface to the middle position of the two stands. The control system activates the electric telescopic rod, the output shaft of the electric telescopic rod drives the rack to move forward, the rack drives the gear to rotate, the gear drives the rotating rod to rotate, the rotating rod drives the inner liner to rotate, the inner liner drives the tension roller to rotate, and the opening on the tension roller rotates away from its original position. Then, starting from the transition end, the tension roller gradually contacts the textile. When the tensioning teeth on the tension roller rotate to the upper surface of the sliding tooth plate, they gradually begin to mesh with the tooth groove. At the same time, the tooth groove and the tensioning teeth also bite the textile between them. The two sets of opposing pre-inspection auxiliary devices rotate in opposite directions to bite the two ends of the textile respectively. The tensioning teeth and grooves work together to generate a horizontal frictional traction force at the meshing point of the fabric. Both ends of the fabric are pulled outward by the traction force, causing the fabric to gradually enter a tensioned state. As the inner liner cylinder drives the tensioning roller to rotate further, the tensioning roller cannot deflect further under the reverse tension force exerted on it by the fabric. At this point, the tensioning roller stops, the inner liner cylinder continues to rotate, the distance between the convex strip and the groove wall decreases, the rotary spring is compressed, and the arc-shaped rod extends into the sliding hole until it reaches the bottom of the sliding hole and squeezes the inductive switch. After being pressed, the inductive switch sends a signal to the control system. Upon receiving the signal, the control system pauses the operation of the electric telescopic rod, and the tension detection component stops to avoid excessive tension, which could damage the fabric and affect the flatness detection accuracy. The fabric remains in a tensioned state, and the tension detection component enters the tensioning mode.

[0013] After the textile fabric is in a taut state, the control system activates the intelligent robotic arm. Based on the positioning information of the control system, the intelligent robotic arm drives the laser detector to align with the interface position. The laser detector scans the interface, and in conjunction with the control system, performs fine detection and evaluation of the interface's flatness, thereby achieving the purpose of intelligent positioning and accurate flatness detection of the interface.

[0014] When strength testing of the fabric joint is required, in tension mode, the control system reactivates the electric telescopic rod, extending its output shaft to further rotate the tension detection component. The traction force at both ends of the fabric gradually increases until the required strength for testing is reached. The control system controls the deflection angle of the tension detection component by adjusting the extension of the electric telescopic rod's output shaft; a larger deflection angle results in a greater traction force, thus adjusting the traction force and activating the strength detection component. Once the traction force reaches the required strength, the control system scans the joint using a laser detector. The control system analyzes the degree of damage at the joint, thereby achieving the purpose of strength testing of the fabric joint.

[0015] Furthermore, the inner liner is equipped with a connecting frame, and the inner liner is mounted on the rotating rod through the connecting frame. The inner liner has a groove, and a convex strip is located in the groove. A rotary spring is installed between the convex strip and the groove wall. A sliding hole is opened on the groove wall, and the arc-shaped rod is slidably connected to the sliding hole. An inductive switch is installed in the sliding hole.

[0016] Furthermore, the detector includes a hollow shell mounted on a rotating rod, a detection rod slidably mounted inside the hollow shell, the bottom end of the detection rod being connected to a movable cylinder, a contact slidably mounted inside the hollow shell, a detection spring being installed between the contact and the detection rod, an elastic diaphragm being installed inside the hollow shell, a piezoelectric crystal being installed between the elastic diaphragms, and the contact being in close contact with one side of the elastic diaphragm.

[0017] During operation, two sets of electric winding rollers drive the textile fabric to be inspected to move and rewind. The lower surface of the textile fabric moves on the frame and pad assembly. The pre-inspection auxiliary device is in flatness detection mode. The detection roller is in close contact with the upper surface of the textile fabric. Under the action of friction between the textile fabric and the detection roller, the detection roller rotates around the movable cylinder. Due to the open design at the bottom of the tension roller, the tension roller does not come into contact with the textile fabric. Due to the overlapping stitching at the interface of the textile fabric, a protrusion is formed at the interface. When the interface on the textile fabric passes the detection roller, it will push the detection roller upward. Under the limiting action of the T-shaped rod and the sliding ring, the detection roller drives the movable cylinder to move vertically upward along the direction of the T-shaped rod. The movable cylinder simultaneously drives the detection rod to slide upward in the hollow shell, which compresses the detection spring. The compressed detection spring squeezes the piezoelectric crystal in the elastic diaphragm through the contact. The piezoelectric crystal generates an electrical signal under pressure. When the sewing process at the interface of the textile fabric is qualified, the height of the protrusion at the interface fluctuates little compared with the standard value. The control system compares the received electrical signal with the electrical signal value corresponding to the standard value to make a preliminary judgment on the sewing process of the textile fabric and realize the initial inspection of the flatness of the textile fabric interface. At the same time, the generation of the electrical signal also allows the control system to use the time node of the electrical signal generation, in conjunction with the moving speed of the textile fabric, and combined with the algorithm to locate and track the interface position.

[0018] Furthermore, the pad assembly includes a fixed pad, one end of which is connected to the frame, and an L-shaped end plate is symmetrically installed on the other end of the fixed pad. A sliding rod is installed between the L-shaped end plate and the frame, and a sliding toothed plate is slidably installed on the sliding rod. The toothed plate has toothed grooves, and a tension spring is installed between the sliding toothed plate and the L-shaped end plate.

[0019] The toothed grooves are matched with the size and number of tensioning teeth. When the sliding toothed plate engages with the tensioning roller, it slides on the sliding rod to maintain engagement with the tensioning roller, ensuring that the textile fabric is always engaged. As the sliding toothed plate moves, it drives the tension spring to stretch. When the detection ends and the tension detection component resets, the tension spring drives the sliding toothed plate to retract and reset.

[0020] Furthermore, the drive unit includes an electric telescopic rod, which is mounted on a crossbeam. A rack is mounted on the output shaft of the electric telescopic rod, and the rack meshes with a gear for transmission.

[0021] Compared with the prior art, the beneficial effects of the present invention are: 1. The control system applies the required traction force to both ends of the woven fabric for strength testing, in conjunction with a laser detector, to achieve the purpose of testing the joint strength of the woven fabric. The control system controls the deflection angle of the tension detection component by controlling the extension of the output shaft of the electric telescopic rod. The larger the deflection angle, the greater the traction force, thereby achieving adjustment of the traction force.

[0022] 2. By adjusting the tension detection component in multiple modes, multiple functions such as preliminary pre-detection of interface flatness, auxiliary detection of textile tension and interface strength can be achieved with only a single component, thus achieving the purpose of structural integration and simplification.

[0023] 3. The detection roller converts the protrusion at the interface of the textile fabric into a vertical upward displacement of the movable cylinder. This causes the compressed detection spring to squeeze the piezoelectric crystal in the elastic diaphragm through the contact. The piezoelectric crystal generates an electrical signal under pressure. The control system compares the received electrical signal with the electrical signal value corresponding to the standard value to make a preliminary judgment on the sewing process of the textile fabric and achieve the purpose of initial inspection of the flatness of the textile fabric interface. 4. The control system uses the time node of the electrical signal generation, the moving speed of the textile fabric, and the algorithm to locate and track the interface position. After the interface passes the initial inspection, the intelligent robotic arm uses the positioning information of the control system to drive the laser detector to align with the interface position. The laser detector scans the interface, and the control system performs fine detection and evaluation of the interface flatness, thereby achieving the purpose of intelligent positioning and accurate flatness detection of the interface.

[0024] 5. The tension detection assembly is rotated by an electric telescopic rod, causing the tensioning teeth on the tensioning roller to mesh with the tooth grooves, thus gripping the fabric. The meshing of the tensioning teeth and tooth grooves generates a horizontal frictional traction force on the fabric, while both ends of the fabric are pulled outwards, gradually bringing the fabric into a tensioned state. A stop signal is generated by pressing the inductive switch with an arc-shaped rod. Upon receiving the signal, the control system stops the tension detection assembly to prevent excessive tension from damaging the fabric and affecting the flatness detection accuracy, thereby achieving the purpose of fabric tensioning and providing conditions for subsequent laser inspection.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1-9 As shown, this invention provides a technical solution for a textile fabric flatness testing device with intelligent positioning function: It includes a support 1, an electric winding roller 2 rotatably mounted on the support 1, a platform 3 mounted on the support 1, crossbeams 7 symmetrically mounted between the platforms 3, a pre-inspection auxiliary device 6 mounted between the crossbeams 7, an intelligent robotic arm 4 mounted on the platform 3, and a laser detector 5 mounted on the intelligent robotic arm 4.

[0029] Two sets of electric winding rollers 2 are symmetrically arranged. The textile fabric is wound around the electric winding rollers 2. One end of the electric winding roller 2 is used to unwind the textile fabric, and the other end is used to rewind the textile fabric. The textile fabric passes through the pre-inspection auxiliary device 6. The pre-inspection auxiliary device 6 is divided into two groups, which are respectively set on the sides of the two frames 3.

[0030] The pre-inspection auxiliary device 6 includes a drive device 61 and several pad assemblies 62. The pad assemblies 62 are installed at one end of the frame 3. The drive device 61 is installed on the crossbeam 7. A connecting end 71 is installed on the crossbeam 7. A rotating rod 63 is rotatably installed between the connecting ends 71. A tension detection assembly 64 is installed on the rotating rod 63. Gears 65 are installed at both ends of the rotating rod 63. The gears 65 mesh with the drive device 61 for transmission.

[0031] Each pre-inspection auxiliary device 6 includes several pad assemblies 62 and several tension detection assemblies 64. Several pad assemblies 62 are arranged in a row and set on the side of the frame 3. Several tension detection assemblies 64 are connected in series on the rotating rod 63.

[0032] The tension detection assembly 64 includes a movable cylinder 645 and an inner liner cylinder 643. A sliding ring 631 is provided on the rotating rod 63, and a T-shaped rod 632 is slidably installed on the sliding ring 631. The movable cylinder 645 is connected to the bottom end of the T-shaped rod 632. A detector 633 is installed on the rotating rod 63 and is connected to the movable cylinder 645. A detection roller 641 is rotatably installed on the movable cylinder 645. A tension roller 642 is rotatably installed on the inner liner cylinder 643. A rotary spring 644 is installed between the tension roller 642 and the inner liner cylinder 643. The inner liner cylinder 643 is installed on the rotating rod 63.

[0033] The tension roller 642 is provided with tensioning teeth 6422, and an opening 6421 at its bottom end. A transition end 6423 is located at both ends of the opening 6421. The tension roller 642 is provided with a raised strip 6424, on which several arc-shaped rods 6425 are mounted. These arc-shaped rods 6425 are slidably connected to the inner liner 643. A rotary spring 644 is installed between the raised strip 6424 and the inner liner 643. The transition end 6423 is used to trim the cross-section of the opening 6421 to prevent excessive shearing force from damaging the fabric when directly biting it through the cross-section.

[0034] The inner liner 643 is provided with a connecting frame 6431. The inner liner 643 is mounted on the rotating rod 63 through the connecting frame 6431. The inner liner 643 is provided with a groove 6433. A protrusion 6424 is located in the groove 6433. A rotary spring 644 is installed between the protrusion 6424 and the groove wall of the groove 6433. A sliding hole 6434 is opened on the groove wall of the groove 6433. An arc rod 6425 is slidably connected to the sliding hole 6434. An inductive switch 6432 is installed in the sliding hole 6434.

[0035] The detector 633 includes a hollow shell 6331, which is mounted on a rotating rod 63. A detection rod 6332 is slidably installed inside the hollow shell 6331. The bottom end of the detection rod 6332 is connected to a movable cylinder 645. A contact 6334 is slidably installed inside the hollow shell 6331. A detection spring 6333 is installed between the contact 6334 and the detection rod 6332. An elastic diaphragm 6336 is installed inside the hollow shell 6331. A piezoelectric crystal 6335 is installed between the elastic diaphragms 6336. The contact 6334 is in close contact with one side of the elastic diaphragm 6336.

[0036] The pad assembly 62 includes a fixed pad 621, one end of which is connected to the frame 3. An L-shaped end plate 624 is symmetrically installed on the other end of the fixed pad 621. A sliding rod 625 is installed between the L-shaped end plate 624 and the frame 3. A sliding toothed plate 622 is slidably installed on the sliding rod 625. The toothed plate is provided with a toothed groove 623. A tension spring 626 is installed between the sliding toothed plate 622 and the L-shaped end plate 624.

[0037] The toothed groove 623 is matched in size and number with the tensioning tooth 6422. When the sliding toothed plate 622 engages with the tensioning roller 642, it maintains engagement with the tensioning roller 642 by sliding on the sliding rod 625, so that the textile fabric is always engaged. When the sliding toothed plate 622 moves, it drives the tension spring 626 to stretch. When the detection ends and the tension detection component 64 is reset, the tension spring 626 drives the sliding toothed plate 622 to retract and reset.

[0038] The drive unit 61 includes an electric telescopic rod 611, which is mounted on the crossbeam 7. A rack 612 is mounted on the output shaft of the electric telescopic rod 611, and the rack 612 meshes with a gear 65 for transmission.

[0039] The working principle of this invention is as follows: During operation, two sets of electric winding rollers 2 drive the textile fabric to be inspected to move and rewind. The lower surface of the textile fabric moves on the frame 3 and the pad assembly 62. The pre-inspection auxiliary device 6 is in flatness detection mode. The detection roller 641 is in close contact with the upper surface of the textile fabric. Under the action of friction between the textile fabric and the detection roller 641, the detection roller 641 rotates around the movable cylinder 645. Due to the design of the opening 6421 at the bottom of the tension roller 642, the tension roller 642 does not come into contact with the textile fabric. Due to the overlapping stitching at the interface of the textile fabric, a convex shape is formed at the interface. When the interface on the textile fabric passes the detection roller 641, it will push the detection roller 641 upward. Under the limiting action of the T-shaped rod 632 and the sliding ring 631, the detection roller 641 drives the movable cylinder 645 to move vertically upward along the direction of the T-shaped rod 632. The movable cylinder 645 simultaneously drives the detection rod 6332 to slide upward in the hollow shell 6331, which compresses the detection spring 6333. The compressed detection spring 6333 squeezes the piezoelectric crystal 6335 in the elastic diaphragm 6336 through the contact 6334. The piezoelectric crystal 6335 generates an electrical signal under pressure. When the sewing process at the interface of the textile fabric is qualified, the height of the protrusion at the interface fluctuates little compared with the standard value. The control system compares the received electrical signal with the electrical signal value corresponding to the standard value to make a preliminary judgment on the sewing process of the textile fabric and realize the initial inspection of the flatness of the textile fabric interface. At the same time, the generation of the electrical signal also allows the control system to use the time node of the electrical signal generation, in conjunction with the moving speed of the textile fabric, and combined with the algorithm to locate and track the interface position.

[0040] After the initial inspection of the interface is qualified, when the flatness of the textile tension is accurately tested, the control system moves the textile interface to the middle position of the two stands 3. The control system activates the electric telescopic rod 611. The output shaft of the electric telescopic rod 611 drives the rack 612 to move forward. The rack 612 drives the gear 65 to rotate. The gear 65 drives the rotating rod 63 to rotate. The rotating rod 63 drives the inner liner 643 to rotate. The inner liner 643 drives the tension roller 642 to rotate. The opening 6421 on the tension roller 642 rotates away from its original position. Then, starting from the transition end 6423, the tension roller 642 gradually contacts the textile. When the tension teeth 6422 on the tension roller 642 rotate to the upper surface of the sliding tooth plate 622, they gradually begin to mesh with the tooth groove 623. At the same time, the tooth groove 623 and the tension teeth 6422 also bite the textile between them. The two sets of opposing pre-inspection auxiliary devices 6 rotate in opposite directions to bite the two ends of the textile respectively. The tensioning teeth 6422 and 623 work together to generate a horizontal frictional traction force at the meshing point of the textile fabric. Both ends of the textile fabric are pulled outwards, causing the fabric to gradually enter a tensioned state. As the inner liner 643 drives the tension roller 642 to rotate further, the tension roller 642, under the reverse tension exerted by the textile fabric, cannot deflect further. At this point, the tension roller 642 comes to a standstill, the inner liner 643 continues to rotate, and the distance between the convex strip 6424 and the groove wall 6433 decreases. The rotary spring 644 is compressed, and the arc-shaped rod 6425 extends into the sliding hole 6434 until it reaches the bottom of the sliding hole 6434 and squeezes the inductive switch 6432. After being compressed, the inductive switch 6432 sends a signal to the control system. After receiving the signal, the control system stops the operation of the electric telescopic rod 611, and the tension detection component 64 stops to avoid excessive tension, damage to the textile fabric, and affect the flatness detection accuracy. The textile fabric remains taut, and the tension detection component 64 enters the tension mode.

[0041] After the textile fabric is in a taut state, the control system activates the intelligent robotic arm 4. Based on the positioning information of the control system, the intelligent robotic arm 4 drives the laser detector 633 to align with the interface position. The laser detector 633 scans the interface and, in conjunction with the control system, performs fine detection and evaluation of the interface's flatness, thereby achieving the purpose of intelligent positioning and accurate flatness detection of the interface.

[0042] When strength testing of the textile joint is required, in tension mode, the control system restarts the electric telescopic rod 611, extending its output shaft to further rotate the tension detection component 64. The traction force at both ends of the textile gradually increases until the required strength for testing is reached. The control system controls the deflection angle of the tension detection component 64 by controlling the extension of the electric telescopic rod 611's output shaft. A larger deflection angle results in a larger traction force, thus adjusting the traction force. The tension detection component 64 then enters the strength testing mode. Once the traction force reaches the required testing strength, the control system scans the joint using a laser detector 5. The control system analyzes the degree of damage at the joint, thereby achieving the purpose of strength testing of the textile joint.
