[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 This utility model provides a technical solution:
[0026] A multi-point defect detection workbench for polyester-viscose woven fabric includes a workbench body 1, a detection assembly 2 on the top of the workbench body 1, conveying assemblies 3 on both sides of the top of the workbench body 1, and a support mechanism 4 at the bottom of the workbench body 1. The support mechanism 4 includes:
[0027] The tensioning assembly 41 includes a support plate 411 installed at the bottom of the platform 1. A bearing plate 412 is slidably connected to the inner wall of the support plate 411. A connecting plate 413 is fixedly connected to the bottom of the bearing plate 412. An inclined groove 414 is provided on the surface of the connecting plate 413. A bearing rod 415 is fixedly connected to the top of the bearing plate 412. The surface of the bearing rod 415 is slidably connected to the interior of the platform 1. The top end of the bearing rod 415 extends through to the top of the platform 1 and is fixedly connected to a horizontal plate 416. A pressure sensor 417 is fixedly connected to the top of the horizontal plate 416. A fixing plate 418 is fixedly connected to the detection end of the pressure sensor 417. A support frame plate 419 is fixedly connected to one side of the fixing plate 418.
[0028] The drive component 42 is located on the top of the support plate 411 and is used to adjust the height of the support frame plate 419.
[0029] The buffer assembly 43 is located at the bottom of the fixed plate 418.
[0030] A fabric roller is installed on the left side of the platform 1, and a winding roller is installed on the right side of the platform 1. The winding roller is driven to rotate by a motor, thereby realizing the winding operation of the fabric.
[0031] The top of the support plate 411 is equipped with a limiting slide rail for the drive plate 422 to slide in a limited manner;
[0032] The support frame 419 is a transparent frame and has multiple sets of lamps installed inside, which facilitates defect detection by the industrial camera 25.
[0033] As the core component of tension detection, the pressure sensor 417 adopts a high-precision S-type tension sensor. Its measurement range of 0-500N can meet the detection requirements of polyester-viscose woven fabrics of different thicknesses. The accuracy class of 0.1 ensures accurate response even when the tension changes slightly, providing reliable data for subsequent tension adjustment.
[0034] In this embodiment, the drive assembly 42 includes an electric telescopic rod 421 installed on the top of the support plate 411. The output end of the electric telescopic rod 421 is fixedly connected to a drive plate 422. Drive blocks 423 are fixedly connected to both sides of the drive plate 422. The surface of the drive block 423 is slidably connected to the inner surface of the inclined slide groove 414.
[0035] By incorporating a tensioning component 41, and utilizing structural components such as a support frame plate 419, a fixing plate 418, and a buffer component 43 in conjunction with a pressure sensor 417, the pressure of the polyester / viscose woven fabric during the conveying process can be fed back in real time. Furthermore, by using a pre-set threshold on the control panel 26, the electric telescopic rod 421 is automatically adjusted. The transmission design of the inclined slide 414 and the drive block 423 enables automatic adjustment of the height of the support frame plate 419, thereby achieving closed-loop tension control with an adjustment accuracy of ±0.5N. This avoids fabric wrinkles caused by improper tension control, which could affect detection accuracy.
[0036] In this embodiment, the buffer assembly 43 includes a buffer rod 431 installed at the bottom of the fixed plate 418. The surface of the buffer rod 431 is slidably connected to the inside of the horizontal plate 416. A buffer spring 432 is sleeved on the surface of the buffer rod 431. One end of the buffer spring 432 is fixedly connected to the bottom of the fixed plate 418, and the other end of the buffer spring 432 is fixedly connected to the top of the horizontal plate 416.
[0037] In this embodiment, the conveying assembly 3 includes conveying plates 31 installed on both sides of the top of the platform 1. The inner side of the conveying plate 31 is rotatably connected to a conveying roller 32. The upper pressure roller 33 slides inside the conveying plate 31 through an adjustment assembly. A positioning assembly 34 is provided on one side of the conveying plate 31.
[0038] The adjustment assembly includes an adjustment block and an adjustment screw. The upper pressure roller 33 is rotatably mounted inside the adjustment block, while the adjustment screw is rotatably mounted inside the conveyor plate 31. The surface of the adjustment screw is threadedly connected to the inside of the adjustment block. By rotating the adjustment screw, the height of the adjustment block and the upper pressure roller 33 can be adjusted. The surface of the conveyor plate 31 is provided with a sliding groove for sliding and limiting the adjustment block.
[0039] In this embodiment, the positioning assembly 34 includes a positioning seat 341 installed on one side of the conveyor plate 31. A positioning motor 342 is fixedly connected to one side of the positioning seat 341. One end of the output shaft of the positioning motor 342 is fixedly connected to a bidirectional lead screw 343 through a coupling. A positioning block 344 is threadedly connected to the surface of the bidirectional lead screw 343. The surface of the positioning block 344 is slidably connected to the interior of the positioning seat 341. A positioning plate 345 is fixedly connected to the top of the positioning block 344.
[0040] The positioning motor 342 is a three-phase asynchronous motor and is connected to an external power supply via a circuit.
[0041] The bidirectional lead screw 343 rotates inside the positioning seat 341, and the top of the positioning seat 341 is provided with a sliding groove for the positioning block 344 to slide and limit.
[0042] In this embodiment, the detection assembly 2 includes a detection plate 21 installed on the top of the platform 1. A cylinder 22 is fixedly connected to the top of the detection plate 21. A lifting plate 23 is fixedly connected to the bottom of the cylinder 22 through a piston rod. A light lamp 24 is installed at the center of the bottom of the lifting plate 23. Multiple industrial cameras 25 are installed at the bottom of the lifting plate 23. A control panel 26 is installed on one side of the detection plate 21. The control panel 26 is electrically connected to the industrial cameras 25.
[0043] The control panel 26 is electrically connected to the cylinder 22, the positioning motor 342, the light 24 and the electric telescopic rod 421 respectively;
[0044] Cylinder 22 is an SC63×100 model cylinder.
[0045] By setting up a positioning component 34 and using a positioning motor 342 to drive it, the distance between the two positioning plates 345 can be flexibly adjusted. The two sets of positioning plates 345 can keep the polyester-viscose woven fabric in the center during the conveying process, thereby avoiding the polyester-viscose woven fabric from shifting during the conveying process, thus improving the quality of subsequent detection of defects on the surface of the polyester-viscose woven fabric. The spring damping structure of the buffer component 43 can absorb more than 80% of the instantaneous impact load, effectively protecting the pressure sensor 417 and the fabric, extending the service life of the equipment, and reducing the defect rate.
[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0047] When in use, the polyester-viscose woven fabric roll is installed on the fabric roller, and the fabric is pulled through the conveying roller 32 and the upper pressure roller 33 of the conveying assembly 3, the top of the support frame plate 419 and the two sets of positioning plates 345 in sequence, and finally fixed on the take-up roller.
[0048] The pressure of the upper pressure roller 33 is adjusted by adjusting the component. The adjusting component drives the adjusting block and the upper pressure roller 33 to slide up and down synchronously by rotating the adjusting screw. The adjusting block slides inside the conveyor plate 31. The positioning motor 342 is started to drive the bidirectional screw 343 to rotate. When the bidirectional screw 343 rotates, the positioning blocks 344 on both sides slide in the groove opened on the top of the positioning seat 341, so that the positioning plates 345 on both sides slide synchronously to the opposite side to clamp the edge of the fabric. Then, the equipment is started and the winding roller drives the fabric to move at a uniform speed. The synchronous illumination lamp 24 and the lamp tube installed inside the support frame plate 419 are turned on at the same time, so that the industrial camera 25 can take multiple pictures of the fabric surface. The image data is transmitted to the control panel 26 for analysis and processing.
[0049] During tension adjustment, the pressure sensor 417 monitors the pressure on the support frame plate 419 in real time. When the tension deviates from the set value, the control panel 26 controls the electric telescopic rod 421 to move. The electric telescopic rod 421 drives the drive plate 422 and drive block 423 to slide, so that the drive block 423 slides on the inner surface of the inclined slide groove 414, thereby pulling the connecting plate 413. This causes the connecting plate 413, the bearing plate 412, the bearing rod 415, the cross plate 416, the buffer assembly 43, and the support frame plate 419 to rise and fall synchronously until the tension returns to the normal range. The buffer assembly 43 absorbs the impact when the fabric shakes, ensuring the stability of the detection process.
[0050] When a defect is detected, the control panel 26 records the location information and alarms on the display screen. The operator can mark the defect location according to the prompts, and the fabric that has been inspected is wound up by the take-up roller.
