Problems solved by technology

However, the efficiency of manual troubleshooting is low, and when the production volume is large or the labor cost is too high, it often brings a large economic burden to the production enterprise, and it is difficult to meet the production needs of modern large-scale PVC masks.
[0004] In actual production, since the recognition resolution on the PVC mask is relatively high, its imaging accuracy is inversely correlated with the field of view of the image sensor. The field cannot cover the entire PVC mask, which poses a huge challenge for manufacturers to use image sensors to detect large-sized PVC masks

[0038] figure 1 A schematic structural view of a PVC mask detection device 10 according to an embodiment of the present invention is shown, figure 2 A functional block diagram of the PVC mask detection device 10 provided by the embodiment of the present invention is shown. combined reference figure 1 as well as figure 2, the PVC mask detection device 10 includes a control device 600 , a transmission mechanism 400 , an image sensor 200 and a marking device 300 , and the transmission mechanism 400 , the image sensor 200 and the marking device 300 are all connected to the control device 600 .

[0039] Before the PVC mask detection device 10 is used for the printing quality detection of the PVC mask, the preset detection position for the detection of the mask to be checked is demarcated in advance, and N (N is an integer greater than or equal to 2) for the image collection of the mask to be checked The preset acquisition position and the corresponding preset image acquisition...

[0052] image 3 A flow chart of a PVC mask detection method provided by an embodiment of the present invention is shown. refer to image 3 , PVC mask detection methods include:

[0053] Step S10: the control device 600 in the PVC mask detection device 10 controls the transmission mechanism 400 in the PVC mask detection device 10 to transmit the tested mask to a preset detection position, where N Preset collection location.

[0054] Since in step S11, the image sensor 200 always performs image acquisition at fixed N (N is an integer greater than or equal to 2) preset acquisition positions, so in step S10 it is necessary to transmit the inspected mask to the preset acquisition location. Only at the preset detection positions where the positions match, can it be ensured that the N partial inspected mask images collected by the image sensor 200 in step S11 can cover the entire inspected mask. Therefore, step S10 is actually a process of conveying and positioning the tested mas...

Abstract

The invention relates to the technical field of PVC facing films, and provides a PVC facing film detection method and device. The method comprises the following steps: firstly, a conveying mechanism is controlled by a controlling device in the PVC facing film detection device to convey to-be-detected facing films to the preset detection positions; then, an image sensor is controlled by the controlling device to collect and obtain N partial to-be-detected facing film images, corresponding to N preset collecting positions, of the to-be-detected facing films; then, the controlling device pieces the N partial to-be-detected facing film images together into a current facing film image and judges whether the degree of error between the current facing film image and the preset facing film image exceeds a preset error degree or not; and when the judgment result is yes, a marking device adds an error mark at a preset mark position of the to-be-detected facing films under the control of the controlling device. According to the method, the PVC facing film detection method is applied to the PVC facing film detection device, the device can realize automatic detection and error marking of a large-size PVC facing film, the detection process is efficient and accurate, and the cost of manpower resources can be saved for a PVC facing film production enterprise.

Description

technical field [0001] The invention relates to the technical field of PVC facial masks, in particular to a detection method and device for PVC facial masks. Background technique [0002] The electronic and electrical nameplate or sign made of PVC plastic is one of the important parts of electronic products, and it plays an increasingly important role in modern electronic equipment. The production of PVC masks mostly adopts the simple and fast screen printing method. By designing a fixed screen printing template, large-scale and rapid production of PVC masks can be carried out. However, due to the limitation of the technical level, in the screen printing of PVC mask silk, sometimes the words, lines or symbols on the PVC mask are not neat, the brightness is poor, the writing is not plump, jagged, broken lines, virtual edges and bullet oil There may also be serious quality problems such as light transmission and cross-color of PVC masks. [0003] After the above problems ari...
