Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabrics, and particularly relates to a cotton grabbing device with a visual detection function. Background Art

[0002] In the production process of 100% cotton spunlace non-woven fabrics, after the cotton passes through the cotton grabbing machine, opening and cleaning machine, foreign fiber machine and other equipment to form the spunlace non-woven fabric, many defects will remain on the fabric surface, and a lot of costs need to be spent in the fabric inspection process to remove these defects. This is because the raw material, i.e. cotton, will be mixed with a lot of foreign matter during the picking, processing, transportation and storage process, such as waste cotton, plastic film, oily stains, etc. If these missed foreign matter cannot be effectively removed, they will be broken after the opening and cleaning combing process, forming small defects mixed on the surface of the 100% cotton spunlace non-woven fabric, which will seriously affect the cost and efficiency of the fabric inspection process in the production process of 100% cotton spunlace non-woven fabrics. In the existing 100% cotton spunlace non-woven fabric production process, the foreign matter contained in the cotton can be screened out by the foreign fiber machine during the opening and cleaning process. Because the cotton flow speed is fast and it is easy to be wrapped in the fiber group, there are many missed inspections.

[0003] In the prior art, relatively obvious foreign matter can be separated during cotton grabbing, thus avoiding the subsequent crushing to generate a large number of small foreign matter.

[0004] For example, the patent with application number CN202010320373.2 discloses an intelligent cotton picking management system, including a cotton bale data detection module, a cotton bale data processing module, a machine vision detection module, an intelligent judgment and decision-making module, a mechanical execution control module and a cotton picking device; the cotton bale data processing module is used to process the cotton bale data detected by the cotton bale data detection module; the machine vision detection module is used to detect and process visual signals; the intelligent judgment and decision-making module performs intelligent judgment and decision-making based on the cotton bale data and the visual signal, obtains the operating parameters of the cotton picking device, and sends the operating parameters to the mechanical execution control module; the mechanical execution control module controls the operation of the cotton picking device.

[0005] For example, the patent with application number CN202410049542.1 discloses an automatic impurity removal device for cotton spinning three yarns based on source impurity removal, and the automatic impurity removal device for cotton spinning three yarns based on source impurity removal is arranged on the cotton grabbing arm of the cotton grabbing machine, which includes an image acquisition module for visually photographing the surface of the cotton bale along the cotton grabbing path of the cotton grabbing machine, a visual recognition module for identifying foreign objects in the collected images through a visual learning model; and an impurity removal module for clamping and removing identified foreign objects from the cotton bale; wherein the impurity removal module is arranged at the front end of the gripper of the cotton grabbing arm along the cotton grabbing path of the cotton grabbing machine.

[0006] The above patents all set up image acquisition modules, visual recognition modules and execution modules in the cotton plucker to automatically realize image recognition and pick out foreign objects (implemented by the execution module). However, the modification of the cotton plucker is large and the cost is high; in addition, cotton wool is flying around the cotton plucker, which can easily reduce the accuracy or life of the execution module.

The reciprocating cotton plucking machine includes a slide rail 1 arranged in a front-to-back direction, a base 2 on the slide rail 1 and capable of moving forward and backward, a cotton plucking arm 3 on the left or right side of the base 2, and a control box at the top of the base 2. The left and right sides of the slide rail 1 are both placement areas for placing cotton bales 4. The cotton plucking arm 3 is arranged in a left-to-right direction, can rotate 180°, can move up and down on the base 2, and is located directly above the cotton bale 4. The control box is used to control the reciprocating cotton plucking machine. The image acquisition module includes two image acquisition units, which are respectively located on the front and rear sides of the cotton plucking arm 3. The image acquisition unit includes a surface light source 5 and a camera 6 thereon. The surface light source 5 is arranged horizontally and downwardly, and a circular hole is provided on it for the camera 6 to pass through, which is specifically a rectangular light board arranged in a left-to-right direction. The camera 6 is arranged vertically downward and is located in the circular hole. The foreign matter collection groove 15 is located at one end (left end or right end) of the cotton grabbing arm 3 away from the slide rail 1. It is specifically a rectangular groove for placing foreign matter picked up by the operator. The placement area is divided into multiple detection areas 8 (width (front and back direction) is 0.5-1.5m) by multiple dividing lines 16 (preferably distributed at equal intervals) arranged side by side in front and back. Each detection area 8 is marked with a specific label 9. Label 9 is located on the side of the detection area 8 away from the slide rail 1. It is arranged side by side with the cotton bale 4 on the left and right. It cannot be covered by the cotton bale 4. It is specifically a positive integer starting from 1. The label 9 of the detection area 8 is numbered in sequence according to the moving direction of the cotton grabbing arm 3. The alarm module 7 is arranged on the upper side of the surface light source 5 or the upper side of the cotton grabbing arm 3, and includes one or more sound and light alarms; specifically, the surface light source 5 is arranged on the lower side of the bracket 10, and the alarm module 7 and the camera 6 are fixed on the bracket 10. The visual recognition module is used to process the image and output the detection result, which is a conventional structure.

The fixed arm 13 is located on the side of the vertical arm 11 away from the cotton grabbing arm 3. It is a rectangular frame structure (the four sides are basically flush with the four sides of the surface light source 5) that cooperates with the surface light source 5, and is located at the upper part of the vertical arm 11. The surface light source 5 is fixed on the lower side of the fixed arm 13. A plurality of (at least two) inclined supports 14 are provided between the upper end of the vertical arm 11 and the middle part of the upper side of the fixed arm 13. The inclined supports 14 extend obliquely downward from the vertical arm 11 to the fixed arm 13, and the camera 6 is fixed on the inclined supports 14. Specifically, the alarm module 7 includes four sound and light alarms (to ensure the alarm effect and the operator can see them in all directions), two of which are located at the left and right ends of the front end of the front fixed arm 13, and the other two are located at the left and right ends of the rear end of the rear fixed arm 13.
