Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will explain the specific embodiments of the present invention with reference to the accompanying drawings. It is evident that the drawings in the following description are only examples of the invention, from which other drawings and other embodiments can be obtained by a person skilled in the art without inventive effort.
The embodiment of the invention discloses a novel sheet plane vision detection and thickness detection system which is used for detecting the thickness and surface quality of a coating material on the surface of a material belt. Fig. 1 is an exemplary schematic diagram of a system, from which it can be seen that the system includes: a support frame platform 10; a plurality of guide rollers 20 disposed on one side surface of the support frame platform for moving the material tape; the thickness detection mechanism 30 is arranged on the supporting frame platform and is arranged on the surface on the same side as the guide roller; two distance sensing devices in the thickness detection mechanism are respectively arranged on the two side surfaces of the material belt to detect the thickness of the coating material on the surface of the material belt; the surface detection mechanism 40 is arranged on the supporting frame platform and is arranged on the surface on the same side as the guide roller; the surface detection mechanism comprises an imaging device and a light source device, and is configured on the surface of the material belt to detect the surface quality of the coating material on the surface of the material belt.
In this embodiment, the thickness detection mechanism and the surface detection mechanism are designed on the same support frame platform, so that the thickness detection and the surface quality detection of the coating material on the surface of the material strip are respectively realized. Here, the shape and the material used for the support frame platform are not particularly limited as long as the object can be achieved since it achieves the supporting effect. For example, the support frame platform is a C-shaped metal bracket or the like.
A plurality of guide rollers are arranged on the surface of one side of the supporting frame platform to drive the material belt to move on the system, and the thickness and surface quality are detected in the moving process of the material belt. The number of the guide roller arrangements can be adjusted according to the practical application, and is not particularly limited here as well, for example, 2, 4, 5, 7 or more are arranged. The material belt moves under the drive of the guide roller, can be prepared by adopting foil materials, and can also be prepared by adopting other similar materials in practical application.
The surface detection mechanism detects the surface quality of the coating material on the surface of the material belt in an optical imaging mode, and comprises imaging equipment and light source equipment, wherein the imaging equipment and the light source equipment are arranged on the surface of the material belt, and the coating material on the surface of the material belt is shot when the material belt passes through. The coating material on the surface of the web is not particularly limited here as long as it is coated on the surface of the web to form a thin film and can move along with the web on the guide roller, for example, the coating material is an electrode material or the like.
The thickness detection mechanism is used for detecting the thickness of the coating material on the surface of the material belt, and a single distance sensor cannot measure the thickness of the coating material on the surface of the material belt, so that the purpose is achieved in the mode that distance sensing equipment is respectively arranged on the two side surfaces of the material belt in the embodiment, and the two distance sensors respectively detect the one side surface of the material belt, so that the total thickness of the coating material on the surface of the material belt is obtained according to the two detection results. The distance sensor may be selected according to practical application, for example, a laser sensor for detecting the distance between the sensing probe and the upper surface of the coating material. For the configuration mode of the distance sensor, the distance sensor can be arranged along the direction vertical to the surface coating material for the convenience of measurement; of course, the configuration may be performed along other angles, and the calculation may be performed according to the configuration angle.
In an example, as shown in fig. 2, the supporting frame platform 19 includes a first supporting portion 11 and a second supporting portion 12, where a first guiding roller 13 is fixed on the first supporting portion 11, a second guiding roller 14 is fixed on the second supporting portion 12, the first guiding roller 13 and the second guiding roller 14 are disposed on the same horizontal plane, and the material belt 18 moves between the first guiding roller 13 and the second guiding roller 14 along the horizontal direction. A third support portion 15 is further disposed between the first support portion 11 and the second support portion 12, and a first distance sensing device 16 and a second distance sensing device 17 are disposed in the longitudinal direction of the third support portion 15; the material strip 18 passes through the first distance sensing device 16 and the second distance sensing device 17 under the driving of the first guide roller 13 and the second guide roller 14, the first distance sensing device 16 detects the distance between the sensing probe and the upper surface of the coating material on one side surface of the material strip 18 when the material strip 18 passes through, and the second distance sensing device 17 detects the distance between the sensing probe and the upper surface of the coating material on the other side surface of the material strip 18 when the material strip 18 passes through.
In this example, the first distance sensor and the second distance sensor are disposed between the first guide roller 13 and the second guide roller 14, and the first distance sensor and the second distance sensor are disposed opposite to each other in the longitudinal direction on both sides of the surface of the coating material when the web 18 passes therethrough, where the two distance sensors may be disposed symmetrically or asymmetrically as long as they are disposed in the longitudinal direction. When the first distance sensor and the second distance sensor are laser sensors, after the two sensors detect the distance H1/H2 between the sensing probes and the upper surface of the coating material on the corresponding side surfaces of the material tape 18, the thickness H3 of the material tape is also constant because the distance H between the two sensing probes in the longitudinal direction is constant, so that the total thickness h4=h-H1-H2-H3 of the coating material on the surface of the material tape 18 can be obtained.
It should be understood that, for the sake of convenience in calculation, the distance sensor is disposed in the longitudinal direction in the above example, and the distance value is detected in the longitudinal direction, and in other examples, the distance sensor may be configured in other manners, for example, configured in the horizontal direction as shown in fig. 1, etc., and the passing directions of the guide roller and the material belt may be changed accordingly. Two sets of imaging devices and light source devices are arranged in the surface detection mechanism, wherein one set of imaging devices and light source devices are arranged on one side surface of the material belt passing through, and the other set of imaging devices and light source devices are arranged on the other side surface of the material belt passing through. As shown in fig. 1, two sets of equipment are arranged along the longitudinal direction in cooperation with two guide rollers, one set of equipment is arranged above one guide roller, and the other set of equipment is arranged below the other guide roller, so that when the material belt moves along the guide rollers in a manner of passing through the middle positions of the two guide rollers, the two sets of equipment respectively detect one side surface of the material belt.
In this embodiment, the quality of the coating material on the surface of the material belt is detected by the surface detection structure, and two sets of detection devices are configured to detect the two side surfaces of the material belt respectively. Wherein the light source device is used for providing a light source, and is configured with the side edge of the imaging device; the linear array CCD chip inside the imaging device shoots and images towards the surface of the material belt, so that the defect/size of the coating material is detected. The positions of the light source device and the image forming device on the support frame platform can be designed according to practical situations, such as being arranged on the side of the guide roller. Here, the light source apparatus and the image forming apparatus may be any type of apparatus capable of achieving the object of the present invention in the related art, and are not particularly limited herein.
In another embodiment of the present invention, the novel sheet plane vision inspection and thickness inspection system further comprises: and the industrial personal computer is respectively connected with the thickness detection mechanism and the surface detection mechanism and is used for receiving and processing the detection results of the thickness detection mechanism and the surface detection mechanism.
The processing process of the industrial personal computer comprises the steps of checking OK/NG and bad marks in the whole production line, carrying out manufacturing parameter correction on a roller press at the front section of the measuring system in the production process, and carrying out auxiliary marks on bad areas at the rear end of the measuring system. In addition, the industrial personal computer is also connected with a sheet plane visual detection and thickness detection system, so that the coating operation of the roller press at the front section is modified and controlled according to the detection result, and the closed-loop adjustment and the accurate control of the product quality are realized. In the detection system, the thickness detection equipment and the optical imaging equipment are integrated together, and compared with independent control in the prior art, the system is simpler and more convenient, can save manpower and material resources, and can greatly save the occupied area of the equipment.
In addition, the system also comprises a communication device which is respectively connected with the thickness detection mechanism, the surface detection mechanism, the film coating device and the industrial personal computer and is used for respectively realizing the communication connection between the industrial personal computer and the thickness detection mechanism, the surface detection mechanism and the film coating device.
In practical application, the communication device can be a switch, and the communication connection between the industrial personal computer and the thickness detection mechanism/the surface detection mechanism/the film coating device is realized through a network port, so that the whole system can be used on line or independently without adding other equipment lines, and the expandability is strong. In other embodiments, the industrial personal computer may also be in communication with the thickness detection mechanism, the surface detection mechanism, and the film coating apparatus in other manners, which are not specifically limited herein.
