Description of the invention: [Technical field of the invention] The present invention relates to a method and structure for image inspection of a partial sticker machine, which is mainly for performing a damage detection on a portion of the polarizing plate after the partial adhesion, so that after the partial sticker is applied The partial board achieved a higher yield. [Prior Art] About 70 years ago (AD 1929), polarizers were invented and patented in the United States. Most of the polarizers were used (microscopes, pilot lenses, and sunglasses...) for military and scientific purposes. Pilots used polarizers to find boats and submarines that sank under the water. After 1937, polarizers were mass-produced and used, manufactured using automated equipment, and made commercially available. The principle of polarizing plate converts the natural light that is not polarized to polarized light. When there is no polarizing plate, the light can enter and exit the liquid crystal cell freely, and is not affected by the applied electric field. However, after the polarizing plate is applied to the upper and lower layers, the light is transmitted. It can be controlled by the electric field and the electric field, so that the change of light and dark can be visually perceived. It can be seen that the polarizing plate is to convert the non-polarizing light into the polarized light, and the liquid crystal display - the polarization of the polarized light plus the liquid crystal torsional characteristics To control the passage of light, to form light and dark. The basic structure of the polarizing plate is made up of several layers of film material with a thickness of only tens of meters, and the most important photon yttrium is used to adsorb the upper-color substance by using a polymer film with good light transmittance (commonly used polyethylene glycol). (硪, dye, etc.), in a few seconds, the broken ions or dyes diffuse into the inner layer of μ in the second micro = after the human or mechanical stretching, straight Wei times, and will become a The original PVA knife is irregularly distributed at any angle. After being stretched, the molecules are gradually deflected in the direction of the force by 1277719, and the moth ions or dyes attached to the PVA are also directional, so they can be miscellaneous. The field component of the beam f parallel to the direction of the beam passes only the beam_electric field component in the vertical direction. In addition, there is a protective layer on both sides of the polarizer. Since the PVA film is extended, the mechanical properties are generally reduced and become easy. Broken, so after the polarizing substrate (PVA) is extended, a transparent substrate composed of cellulose triacetate (TAC) is attached on both sides to protect the polarizer and prevent retraction, and then more than 15 TFT TFTLCD Products will be required to post A layer of optical compensation film to increase the wide angle end of the polarizing plate protective film in a release film on the outer layer coupled to ® crystal groove so New Age. The difficulty in the process of polarizing plate is how to make a completely unbiased polarizer. In particular, the size of the products of the cheeks is large and the size is large, the difficulty of the size is increased, and the process yield will be further reduced. In addition, the current thin display has become one of the trends. At present, the overall thickness of polarized plate mainstream products is about 255//m, and the mainstream is 175/zm in the future. The future trend will emphasize increasingly thinner, and the thinner the product, the harder it is. Not only is the material more expensive, but the yield is also lower, so how the polarizer Weishang can maintain a certain yield test for larger size and thinner product manufacturing. ® Therefore, the detection of the polarizing plate is undoubtedly a very important loop. Once the detection yield of the polarizing plate is not high, the yield of the liquid crystal panel product is relatively lowered. However, the polarizing plate inspection device known in the prior art is known. The most important method is the inspection by human visual inspection. The main purpose is to transport the liquid crystal display panel to be tested to the human visual inspection machine by the feeding device, and perform visual inspection with the microscope set by the machine. It is detected whether there is a defect such as a dead point (MURA) or a bright spot (DOT/LINE) on the liquid crystal display panel after lighting, and the feeding device is sent after the detection is completed, and the human visual inspection method is not only slow in detection. The 1277719 principle, which is easy to misjudge and does not meet the automation requirements. As shown in the first figure, Taiwan's new patent number 578905 LCD panel is illuminated by the automatic image quality detection device. It is a gantry-type cross-frame device that is built across the LCD process. Above the visual inspection device, after the digital camera installed by the cross-frame motion mechanism moves to the fixed point above or below, the liquid crystal display panel (LCD Panel) is turned on and the image is completely captured by the still shooting mode. The system provides computer software analysis to identify defects such as MURA and DOT/LINE. As shown in the second figure, Taiwan's new patent announcement number: M261685 is used to detect defects in glass substrates with polarizing plates on the surface. In the case of the injury, the light source is provided by a light source to illuminate the glass substrate on which the polarizing plate is disposed, and an angle adjusting device connected to the light source is used to adjust the light source to control the light beam to illuminate the surface 5 and to be polarized. The illumination angle of the glass substrate of the board, and then the image sensor senses the defect of the glass substrate on the surface of the polarizing plate For example, the image is displayed with a grayscale change. Finally, an analysis module determines the defect corresponding to the development point according to the grayscale value of the development point. However, the conventional techniques described above have a very good rate of manual visual inspection, and the cost is good, and the new type of patent announcement number 578905 liquid crystal display panel (LCDPanel) in Taiwan is automatically detected after the lighting is turned on. , I;, in order to assemble the money to detect the surface to find defects, so in the process of assembly is not able to do a separate test, you need to wait for the assembly to complete the test, find the defect and then eliminate or reorganize the finished product It will waste a lot of manufacturing costs and processing process; Taiwan's new patent announcement number: 媳义5 uses the _ surface to set the polarizing plate of the glass substrate defect detection slightly cap, it must be used - specific beam and Internal _ grayscale imaging processing Ϊ 277719 旎 旎 旎 旎 旎 旎 旎 旎 旎 旎 旎 Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ Ϊ The misjudgment of the copy is really troublesome~ and the detection often causes inaccuracies. SUMMARY OF THE INVENTION The present invention is a method and structure for image inspection of a partial sticker machine, which mainly places a polarized plate after being biased on the detecting device of the present invention, and delivers the polarizing plate after being biased to the stop. In the device, the positioning camera on the stop device of the transmission device first scans the position of the polarizing plate at the time of the placement, and transmits the data after the scanning position to the polarizing plate detection system, and the error is made. The values are annotated and the comparison is analyzed, thereby correcting the scanning error of the polarizing plate by the error value, and then using the positive and negative light sources to illuminate the polarized plate after the biasing, and then performing the surface brooming again by the CCD photographic lens. The line broom image sensing method captures the light source development map of the positive light and the backlight of the polarized plate after the offset, and the computer compares the displacement of the polarizing plate after the partial pasting, the amount of the grinding edge, and the like, and Check the polarizing plate for offset or damage, etc. to ensure the φ quality of the polarizing plate. However, in view of the above-mentioned drawbacks, in the manner of manual visual inspection, it is no longer necessary to use manual-inaccurate visual inspection work, and this automated method greatly reduces the cost of human use, and the strict ratio through the present invention. The method can greatly improve the yield; the automatic detection device for the image quality after the new type patent announcement number 578905 of the LCD panel is lit up in the present invention. The present invention applies separate detection to the polarizing plate portion without going through the test. After the assembly, the defect is detected; in the case of the Taiwan New Patent Publication No.: Halla's defect detecting device for detecting the glass filament on which the polarizing plate is disposed, the present invention uses an image comparison method to achieve more 8 1277719. The lack of _ test, such as the amount of edging, offset check «, and even the hair is set to the Z stop structure plus the correction sensor function to make it fully automatic, not too much test tone, the whole It is extremely convenient and greatly improved in its use. [Embodiment] As shown in Fig. 3, the method and structure for viewing the scales are as follows: a polarizing plate inspection machine H), the front end of which is a portion of the tilting machine u, which is a surface substrate. Partially attached (4) After φ treatment, it becomes a polarizing plate, and then the processed polarizing wheel is sent to the part of the polarizing plate detecting device η to do the money-checking (although the polarizing plate inspection position can be done with the tilting machine) The machine can also be set on the polarizer of the plum.) The polarizing plate has a few parts of the slab, which is a part of the slab, which is a miscellaneous part. 14, - is the transmission part 15, one is the polarizing plate detection system μ; with the fourth picture, but the broom part ls is divided into several units: - ccd camera m 'the department is responsible for The polarizer is a complete broom, and the broom can be roughly divided into a face broom and a line broom. The face broom image technology (also known as a face array, matrix or progressive touch is a two-dimensional Matrix pixel (4)), which takes the entire image information through one exposure time without moving the pixel or CCD camera, but A line broom image sensing is a column-micro sensor (-dimensional) 'sweeping in a certain direction, the same as - taking a column signal, sequentially reading the data, then sweeping the nail-column, and it must Repeated reading of the image Wei can form a whole two-dimensional image plane, and it will transfer the light source development map after the cat to the polarizing plate detection system, but its CCD camera has various models, color, black and white, miniature, High and low resolution, etc., but generally use high-resolution CCD camera; 9 1277719 a mobile support _, of course c_f job - a crane support frame, can be smooth

When the movable support camera moves to the polarizer to be tested, the positive and backlight sources at this time will provide the light source separately or simultaneously to achieve a positive backlight. The development effect enables the CCD camera to scan the development data of the positive and the backlight; and the polarizing plate support frame 14 is divided into the following structures: a propping platform (4), which is firstly transported through the transmission device The polarizing plate with the biased post is transferred to the supporting platform, and when the platform is sent, the anti-collision device is placed in the transmitting portion, and the polarizing plate is placed approximately sensitively, and then placed on the platform. The position of the polarizer is fixed, and the position is sent to the polarizer for analysis and analysis. The analysis is used to achieve the detection and positioning effect. A motor device (4) is installed under the support platform and supports the platform. Connection, but its polarizing plate inspection Measure the age-old age of the cake under the platform and operate the riding device. Hold the polarizing plate for the sweeping part and do the sweeping of the cat. Then pass the polarizing plate after the broom through the transmission device: Match the fifth and sixth figures. The transmission device part 15 is divided into the following structures: : The conveyor belt device 'is usually the same as the transportation belt, and the most important storage plate is sent to the inspection position after the partial polarization, and then the polarized light is measured. The board Wei Wei granules, the conveyor belt device described above is the 権 権 , , , , , , , , , 如 _ 议 议 议 议 议 议 议 议 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 With the polarizing plate (four), it will be biased after the _ light board transmits the reading platform ± 'money to the front of the platform, at the front end of the transmission device, there is a stagnation of the polarizing plate at a specific position. Then, the analysis and comparison are performed on the anti-collision device, and the analysis and comparison are performed to achieve the effect of detecting and positioning. A polarizing plate detecting system 16 can be divided into the following modules. : -Transfer the receiving module, first make the positioning information of the positioning camera to do _ _ action, and will The material is sent to the processing model, and then the (4) part is sent out to the Qingqi material to do-receive, and the broom data is transmitted to the processing module; - Dealing with Huan, Yi «Materials - Sub-reduction, prisons And the inspection position data is made - the comparison produces an error adjustment value, and then the polarizing plate scanning the light source development map is processed and compared with the preset good polarizing plate data to detect the damage between the terminals (including (4) The terminal part is damaged, the Weizi part is damaged, the secret surface, the return, the _, the transfer quantity check, the edging amount check, etc.... The test result is displayed by the display device, and the processing module outputs the predetermined stroke command to the transmission and reception. The module transmits the actuation command to the sweeper, transmits it to the polarizer floor riser section and the transmission device part to sweep the whole body to its best state. The brothers seven, eight, nine and ten maps operate for it. The side view and the top view, in the detection method, firstly, the polarized plate 2 after the partial pasting is passed through the conveyor device 1S1 of the transmission device portion 1S, and the polarized plate 20 after the offset is sent to the partial wire inspection_13 The polarizing plate support table (4) is transported to the polarizing plate When the polarizing plate of the measuring device D supports the platform (4), there is a collision preventing device 152 for stopping the polarizing plate 20 after the 1277719 is pasted at the detecting position of the polarizing plate supporting platform 141, but the polarizing plate 20 after the biasing is placed at this time. There is usually a slight error in the detection position of the polarizing plate supporting platform 141. However, after the positioning of the positioning camera 153 by the stopping device 152, the correcting function is corrected by the polarizing plate detecting system 16 to correct the offset. The position of the polarizing plate 2 is photographed, and the correction value is first stored in the polarizing plate detecting system 16, and then rotated by the polarizing plate supporting platform 141, so that the CCD photographing lens 131 in the scanning portion 13 is scanned. The image sensing method obtains the light source development map of the polarized plate after the biasing, but the scanning image sensing mode is divided into the surface scanning image technology and the line scanning image technology, and the surface scanning image technology (also called the surface) Array, matrix or progressive surface scanning) uses a two-dimensional matrix pixel (pixel) to capture the entire image information in one exposure time without the need to move the pixel or CCD camera. A line scan image sensing is a column of micro sensors (one-dimensional), scanning in a certain direction, while taking a column of signals, sequentially reading the data, and then scanning the next column, and it must be repeated The image information can be read to form an entire two-dimensional image image, and then the scanned light source development image is sent to the polarizing plate detection system 16, and the correction image is corrected in accordance with the correction value previously generated by the polarizing plate detection system 16. After the partial polarizing plate position is compared, compare it with the correct light source developing image, determine whether the polarizing plate after the pasting is damaged, and then send the detected polarizing plate by the transmission device part 15 The belt device 151 is sent to a designated place. In summary, the image inspection method and structure of the partial sticker machine of the present invention not only can achieve the expected practical effect but also is unprecedentedly designed, and has met the requirements of the patent law invention, and is applied according to law. .
