Description

Technical Field

[0001] The utility model belongs to the technical field of fiber cloth detection equipment, and in particular relates to a defect point detection device for fiber cloth surface. Background Art

[0002] Detecting defects on fabric surfaces primarily relies on machine vision technology, which uses CCD cameras and image processing algorithms to automatically detect defects such as holes, oil stains, and foreign matter. Compared to traditional manual inspection, this method not only improves detection speed and accuracy, but also effectively reduces labor costs and improves production efficiency.

[0003] Since the height of the camera used for conventional inspection is relatively fixed, the visual shooting range can only be adjusted by relying on the focal length inside the camera. The adjustment is not intuitive enough, which makes it difficult to adjust the camera viewing distance of conventional fiber cloth defect detection equipment.

[0004] To this end, we propose a defect point detection device for fiber cloth to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the camera viewing distance adjustment of conventional fiber cloth defect detection equipment is relatively troublesome, and to propose a fiber cloth defect detection device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A device for detecting defects on fiber fabric surfaces comprises a lamp holder, wherein the upper portion of the lamp holder is rotatably connected to a rotating drum, the outer portion of the rotating drum being covered with a leather sheath, the rotor of the rotating drum extending through the lamp holder, the upper end of the lamp holder being fixedly connected to a pulley, the rotating drum and pulley being symmetrically provided in a pair, a belt being rotatably sheathed on the pulley, the outer end of the belt being provided with an identification mark, the pair of identification marks being provided, the front portion of the lamp holder being fixedly connected to a probe, the rear portion of the lamp holder being fixedly connected to a fixing frame, the upper portion of the fixing frame being fixedly connected to a guide sleeve, the internal thread of the guide sleeve being provided with a bolt, the internal portion of which is slidably provided with a lifting bar, the lower end of the lifting bar being fixedly connected to a camera, the bolt pressing against the lifting bar. Loosening the bolt releases the lifting bar, and then adjusting the height of the lifting bar, which acts on the camera to adjust the camera's shooting height, and then tightening the bolt to lock the lifting bar, thereby facilitating adjustment of the camera's shooting height. The fiber cloth is pulled along the rotating drum, and the fiber cloth drives the rotating drum to rotate. The rotating drum acts on the pulley, and the pulley drives the belt to rotate. When the identification mark passes by the probe, the probe feeds back information to the intelligent control device. After receiving the feedback from the probe, the camera is driven to shoot the fiber cloth on the rotating drum, which is convenient for collecting fiber cloth images for detection.

[0008] Preferably, a reinforcement rod is fixedly connected to the upper portion of the fixing frame, so as to increase the stability of the upper structure of the fixing frame.

[0009] Preferably, the guide sleeve includes a sleeve body and a nut, wherein the nut is fixedly connected to the front end of the sleeve body, and the inner spaces of the sleeve body and the nut are communicated. The nut facilitates the spiral movement of the bolt, and the sleeve body facilitates the lifting and lowering of the lifting bar.

[0010] Preferably, the guide sleeve includes an elastic sheet, the lower end of which is fixedly connected to the upper end of the sleeve body. The elastic sheet is used to compress the lifting bar, thereby increasing the sliding resistance of the lifting bar and facilitating the suspension of the lifting bar.

[0011] Preferably, the bolt includes a knob and a threaded rod, wherein the knob is fixedly connected to the outside of the threaded rod. The knob is used to increase the length of the operating lever, and manually turning the knob drives the threaded rod to rotate, so that the threaded rod loosens or tightens the lifting strip, thereby facilitating manual operation of the bolt.

[0012] Preferably, a leather block is fixedly connected to the interior of the threaded rod, so as to increase the friction between the bolt and the lifting bar and improve the stability of the bolt pressing the lifting bar.

[0013] Preferably, the lifting bar includes a bar body and a stopper, wherein the stopper is fixedly connected to the upper end of the bar body. The stopper blocks the guide sleeve to limit the downward sliding range of the lifting bar, thereby preventing the lifting bar from falling off.

[0014] In summary, the technical effects and advantages of the utility model are:

[0015] 1. Loosen the bolts to loosen the lifting bar, then adjust the height of the lifting bar. Use the lifting bar to act on the camera to adjust the camera's shooting height. Then tighten the bolts and use the bolts to lock the lifting bar to facilitate adjustment of the camera's shooting height.

[0016] 2. Pull the fiber cloth along the drum and use the fiber cloth to drive the drum to rotate. The drum acts on the pulley, and the pulley drives the belt to rotate. When the identification mark passes the probe, the probe feeds back information to the intelligent control device. After receiving the feedback from the probe, the camera is driven to shoot the fiber cloth on the drum, which is convenient for collecting fiber cloth images for detection.

[0017] 3. Use the knob to increase the length of the operating lever, manually turn the knob to drive the threaded rod to rotate, so that the threaded rod loosens or tightens the lifting bar, making it easier to manually operate the bolt. BRIEF DESCRIPTION OF THE DRAWINGS
