Technical Field

Background

In the production of a film material, in order to ensure the quality of the film material, after the film material is formed, the surface density, thickness and surface condition of the film material need to be detected.

The existing measuring equipment generally transmits rays (such as X rays and beta rays) with certain intensity through a ray transmitting device to penetrate through the pole piece, and then detects the ray intensity of the rays passing through the pole piece through a ray receiving device, so that the surface density of the pole piece is calculated according to the change of the ray intensity. For the possible fine scratches (the width of the scratches is far smaller than the width of the radiation spot), the fine scratches are easily averaged out when the measuring device performs the area density detection, and the existence of the fine scratches is difficult to detect.

The existing measuring equipment is usually provided with two oppositely arranged laser distance measuring devices, the two oppositely arranged laser distance measuring devices are respectively positioned at two sides of the film material, and the distance between the two laser distance measuring devices and the surface of the film material is respectively detected by the two laser distance measuring devices, so that the thickness of the film material is calculated.

In the first, second and third embodiments, the laser measurement module 5 includes the first laser component 51 and the second laser component 52, where the first laser component 51 and the second laser component 52 are disposed opposite to each other, and can measure the thickness of the material located between the first laser component 51 and the second laser component 52, and the first laser component 51 and the second laser component 52 are laser rangefinder, and transmit laser to the object to be measured, and then receive the light reflected by the object to be measured, so as to obtain the distance between the object to be measured and the first laser component 51 and the second laser component 52.

The radiation measurement module 6 includes a radiation receiving component 61 and a radiation emitting component 62, the radiation emitting component 62 includes a radiation emitter capable of emitting radiation, the radiation receiving component 61 is a radiation receiver, the radiation receiving component 61 and the radiation emitting component 62 are oppositely arranged, the radiation emitting component 62 is used for emitting radiation (such as X-rays, beta-rays, etc.), and the radiation emitting component 62 is capable of emitting radiation to the radiation receiving component 61 so as to determine the surface density of the material between the radiation receiving component 61 and the radiation emitting component 62.

The image detection module 7 includes a camera, and is capable of acquiring a surface image of an object to be detected, and analyzing whether scratches, impurities, and the like exist on the surface of the object to be detected.

When in use, one or two of the laser measuring module 5, the ray measuring module 6 and the image detecting module 7 can be opened, and the rest is closed. That is, the laser measuring module 5, the radiation measuring module 6, and the image detecting module 7 may be operated independently as needed, or may be operated together as needed.

The working principle of the measuring device is as follows: the object to be detected is placed between the first laser component 51 and the second laser component 52 and between the radiation emitting component 62 and the radiation receiving component 61, and the image detection module 7 faces the surface of the object to be detected, and then the object to be detected is detected.

When the laser measurement module 5 is used for detecting an object to be detected, the first laser component 51 and the second laser component 52 are used for respectively irradiating the two side surfaces of the object to be detected, so that the distance between one side surface of the object to be detected and the first laser component 51 and the distance between the other side surface of the object to be detected and the second laser component 52 are obtained, and then the distance between one side surface of the object to be detected and the first laser component 51 and the distance between the other side surface of the object to be detected and the second laser component 52 are subtracted by using the distance between the first laser component 51 and the second laser component 52, so that the thickness of the object to be detected is obtained.

When the radiation measuring module 6 is used for detecting an object to be detected, the radiation emitting component 62 of the radiation measuring module 6 emits radiation, the radiation passes through the object to be detected, the radiation receiving component 61 of the radiation measuring module 6 receives the radiation emitted by the radiation emitting component 62, and the intensity of the radiation is analyzed to obtain data of the surface density. When the densities of the objects to be measured are inconsistent, the transmittance of the rays will change, so that the intensities of the rays received by the ray receiving component 61 are inconsistent, and the data of the surface density of the objects to be measured can be accurately obtained. For example, in the case of the same thickness, the light transmittance of the object to be measured having a smaller areal density is larger than that of the object to be measured having a larger areal density.

When the image detection module 7 is used for detecting the object to be detected, the image detection module 7 acquires an image of the surface of the object to be detected, and then whether scratches, impurities and the like exist on the surface of the object to be detected is known by analyzing the condition of the object to be detected in the image. The condition of the surface of the object to be detected can be obtained by comparing the image with the image of the standard object to be detected or analyzing the color value of the surface of the object to be detected.

In the above, the data of the laser measurement module 5, the radiation measurement module 6 and the image detection module 7 may be mutually combined for analysis, so as to improve the accuracy of the detection result. For example: by data combination analysis of the laser measurement module 5 and the radiation measurement module 6, it is known whether the intensity change of the radiation received by the radiation receiving assembly 61 is caused by a density change or a thickness change.

The laser measurement module 5, the ray measurement module 6 and the image detection module 7 are arranged at intervals, so that the phenomenon of mutual interference can not occur between the laser measurement module 5, the ray measurement module 6 and the image detection module 7 during working.

In the embodiment shown in fig. 1, the laser emitted by the laser measurement module 5 and the radiation emitted by the radiation measurement module 6 are perpendicular to (can be within a certain error range) the side surface of the object to be detected, so as to improve the accuracy of the detection data. The image detection module 7 is oriented to the side surface of the object to be detected (within a certain error range), so that the cleaning degree of the image is improved.

In the above, the object to be measured may be a film material or a sheet material, for example, a pole piece.

In some embodiments, the image detection module 7 includes a first camera 71, where a lens of the first camera 71 faces a first direction, and the first direction is a direction facing the object to be detected, so that the first camera 71 can acquire an image on the object to be detected. The first direction may be a direction perpendicular or approximately perpendicular to the surface of the object to be measured to obtain a clearer image.

The lens of the first camera 71 is provided with the first light source 73, and the first light source 73 is used for improving the light efficiency of the image position acquired by the first camera 71, so that the first camera 71 can acquire a clearer image, and the image processing difficulty is reduced.

In some embodiments of the utility model, the second camera 72 and the first camera 71 are disposed on the same mount, and the lens of the second camera 72 faces in a second direction opposite to the first direction. When the device is used, an object to be detected is placed between the first camera 71 and the second camera 72, and the lenses of the first camera 71 and the second camera 72 face towards the object to be detected, so that two side faces of the object to be detected can be detected simultaneously, the object to be detected does not need to be turned over, detection of the two side faces can be achieved, and detection efficiency is improved. In other embodiments, the first camera 71 and the second camera 72 are disposed on one side of the object to be measured, and the first camera 71 and the second camera 72 detect different positions on the same side of the object to be measured.
