Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, and specifically designs a textile cloth detection device. Background Art

[0002] In the production of textile products, fabric surface defects are the main factor affecting the quality of fabrics. The inspection of fabric surface defects is a very important link. Fabric defect detection has always been completed by human eyes. In this way, the speed of manual inspection is 15-20 meters per minute. Manual inspection depends on the experience of fabric inspectors, the proficiency of training and other subjective factors, so there will be problems of false detection and missed detection. At the same time, during the long-term inspection process of fabric inspectors, it will cause eye fatigue, resulting in a decrease in subjective judgment ability. Therefore, the traditional manual inspection method has high labor intensity, high missed detection and false detection rates, and is easily affected by subjective factors. Although there are intelligent detection mechanisms that use cameras to identify the location of fabric defects and mark the defects with a marking pen, the current defect marking usually only drives the marking pen to move in the vertical direction. When the defect is not directly above the defect, the defect position cannot be accurately marked. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a textile fabric detection device which can accurately mark the position of defect points.

[0004] The basic scheme provided by the utility model: a detection device for textile fabrics, comprising an inspection table, on which unwinding rollers and take-up rollers are respectively arranged at two ends of the inspection table, and an inspection device, the inspection device comprising a controller and a camera, a bracket is provided on the inspection table, the bracket comprising a first support rod, a second support rod and a cross rod, the first support rod and the second support rod are respectively arranged on both sides of the inspection table, the first support rod and the second support rod are both electric lifting rods, the two ends of the cross rod are respectively connected to the first support rod and the second support rod, a slider assembly is provided at the lower end of the cross rod, the slider assembly is slidably connected to the cross rod, the camera is arranged at the lower end of the slider assembly, the lower end of the slider assembly is also provided with a marking pen, the slider is driven by a first motor to slide on the cross rod, the input end of the controller is electrically connected to the output end of the camera, the output end of the controller is electrically connected to the input end of the first motor, the output end of the controller is electrically connected to the input end of the electric lifting rod, the controller is used to receive images uploaded by the camera, and the controller is also used to control the first motor and the electric lifting rod to work.

[0005] The principle and advantage of the utility model are: the generated cloth is placed on the unwinding roller on the inspection table, one end of the cloth is wound on the tightening roller, and the tightening roller rotates, so that in the process of winding the cloth from the unwinding roller to the tightening roller, each section of the cloth will pass through the inspection table and be inspected on the inspection table. When the cloth passes through the inspection table, the camera set on the cross bar obtains the image of the cloth passing under the camera, and sends the obtained image to the controller. The controller recognizes the image of the passing cloth through the existing image recognition technology to determine whether the cloth has defects. When there are defects, the tightening of the tightening roller is stopped, and the cloth stops moving. At this time, the defect point is located below the cross bar. By controlling the first support rod and the second support rod to descend, and by moving and sliding, the marking pen moves in the horizontal and vertical directions and finally falls on the defect point. The defect point position is marked by the marking pen, which is convenient for finding the position of the defect point when the cloth is cut later. Avoid the use of defective cloth.

[0006] Compared with the prior art, in addition to enabling the marking pen to move in the vertical direction, the marking pen can also be moved in the horizontal direction, and the mark can be accurately placed on the defect point. At the same time, the camera and the marking pen are both arranged on the slider assembly, and the position of the defect point can be further identified during the movement of the slider assembly, so as to achieve the purpose of accurately locating the defect point.

[0007] Furthermore, the inspection device also includes a storage module, the input end of the storage module is electrically connected to the output end of the controller, and the controller is also used to control the storage module to record the number of defect points.

[0008] The number of defect points in each roll of fabric is recorded through the storage module, and a label can be generated later to indicate the number of defect points in each roll of fabric. When using, the fabric roll with the number of defect points can be selected according to the needs.

[0009] Furthermore, it also includes a second motor, which is used to drive the tightening roller to rotate. The output end of the controller is electrically connected to the input end of the second motor, and the controller is also used to control the operation of the second motor.

[0010] The controller can also control the second motor to work, automatically control the take-up roll to rotate and start detection, and automatically stop after detecting a defect point, and mark the defect point.

[0011] Furthermore, the marking pen is detachably connected to the slider assembly.

[0012] The marking pen is detachably connected, making it easy to remove and replace the marking pen.

[0013] Furthermore, the slider assembly includes a slider body, which is slidably connected to a cross bar via a pulley, a slide groove cooperating with the pulley is provided at the bottom of the cross bar, a push rod is provided at one end of the slider body, the first motor is provided at one end of the cross bar, a screw rod is provided on the output shaft of the motor, and the screw rod is connected to the push rod via a screw nut.

The slider body 7 is slidably connected to the crossbar 6. Specifically, a pulley is provided at the upper end of the slider body 7, and a slide groove matching the pulley is provided at the lower end of the crossbar 6. A first motor 10 is also provided below one end of the crossbar 6, and a screw rod 11 is connected to the output rod of the first motor 10, and the screw rod 11 is connected to a push rod 12 through a screw nut, and the other end of the push rod 12 is connected to the slider body 7.

[0023] It also includes a second motor, a controller, and a storage module, and the second motor is used to drive the tightening roll 3 to work. Figure 3 As shown, the input end of the controller is electrically connected to the output end of the camera 8, and the output end of the controller is electrically connected to the first motor 10, the second motor, the electric lifting rod, and the storage module.

[0024] The specific implementation process is as follows:

[0025] When in use, the cloth to be inspected is placed on the unwinding roller 2, and one end of the cloth is wound on the tightening roller 3. The tightening roller 3 is driven to rotate by the second motor, driving the cloth to be wound from the unwinding roller 2 to the tightening roller 3. When the cloth passes through the inspection table 1, the camera 8 collects the cloth image directly below and sends the image to the controller. After receiving the image, the controller uses the existing image recognition technology to identify whether there is a defect point on the cloth. When there is a defect point, first control the second motor to stop running so that the defect point is located directly below the bracket, and then control the electric lifting rod to lower so that the marking pen moves in the vertical direction. Then, by controlling the first motor 10 to work, the marking pen 9 moves in the horizontal direction. When it is finally located above the defect point, the electric lifting rod is controlled to move down for marking. After the marking is completed, the electric lifting rod and the slider assembly are controlled to reset to complete one marking, and then the second motor is controlled to continue to start. At the same time, the storage module is controlled to record once.
