The invention of the present invention measures the improvement of defects in transparent solid articles. It is to provide a bond with the characteristics of an independent patent claim to achieve the main purpose. As regards the embodiments of the present invention, it is in the dependent patent claims. SUMMARY OF THE INVENTION The present invention discloses a method for 佶, 丨丨 _ 盘. The solid object of the H-111 flip-chip towel defect is exposed to the light from the first-light source, and the sub-detection is in the first place of the exposure, and the spring is based on the exposure of the work light. ,. Therefore, the image of the light of the work light and the fluorescent defect are used as a means for the dust or light deposited on the object; TM Yujin = 15 20 [Embodiment] According to the present invention, a kind has been provided A method for detecting defects in transparent solid objects. According to this method, the solid object is exposed to the under-threshold k from the first source to perform a fingerprint measurement of the fluorescence generated by the solid object in the exposure. In the second step of this method, the image processing of the fluorescence is performed. In this step, the dust particles deposited on the object are distinguished from the fluorescent defects based on the shape, size or color of the emitted gold light. According to the invention, the light emitted from the first light source is transmitted by the solid object 6 200844425: and: two: the fluorescent light emitted by the defect can detect the light in the solid object, and the dust particles can be " : The dust particles on the surface of the f-piece are also fired out. The image processing is based on the size of the ΐϋ/^ or the color, or based on its different color. In color, the pure particles (4) can be associated with the lack of fluorescence, intensity, Saturation, etc. From, color, color τ = particle can be distinguished from defects, according to the invention, this method is also external; that is, it can be carried out in the factory. So the party: , use. In a type of place, 'If a solid object contains a particularly large number of fluorescent defects, it can be regarded as unqualified and the piece is genuine.: The fluorescent defect and solid matter of the coffee piece! I" In the position of the solid object). Fluorescence 15 20 夂: the number of erections can be further determined. In addition, each fluorescent defect and t-shaped heart, pure particles can easily be self-fluorescent neutron-like shape Very long and fuzzy, and more: :: Ming); :r-like. By finding the _object = the case of the defect between the parts, and finding out the possible reasons for the defects of the solid object during the production. According to an embodiment of the present invention, the glory of the debt test After filtering, or after filtering through the second filter and the optical filter, the two transmittances of the ς' can be as high as 25% to (10)% (in terms of the luminescence of the defect), : 7 200844425 8〇/°t 95 /° is better; and its low transmittance is 0% to 20% (in the case of dust particles, k light and mouth is preferably 〇% to ίο%). In contrast, the second filter is low, The shot ratio is 〇/〇 to 2〇〇/. (In terms of the fluorescence emitted by the defect, 〇% to 1〇% is preferred and its high transmittance is 25% to 100% (as far as dust particles are emitted) Fluorescent 5 light and σ, preferably 80% to 95%. The advantage of this embodiment is that the dust particles are easily distinguished from the defects - only the fluorescent particles emitted by the dust particles have a wavelength range Regardless of the fact that the defect is shot. In this case, there is also: advancement advantage. In image processing, only dust particles are emitted based on shape, size or color. The wavelength range of the fluorescent light can make the first filter have a high transmittance, and 10 must be distinguished from the defect. According to an embodiment of the invention, the light emitted by the first light source is in the blue wavelength range or in the ultraviolet In the wavelength range of light, for example, a mercury vapor lamp, a blue laser or a blue LED (light emitting diode) can be used as the first light source. According to an embodiment of the invention, the light emitted by the first light source has a wavelength range. 15 is from 440 nm to 510 nm (440 nm repp. 500 nm to 10 nm). v According to still another embodiment of the present invention, the solid object is exposed to light from the second source according to the method, and is detected by exposure. The light emitted by the solid object and the light reflected by the solid object. Thereby, the detected light is image processed, and non-fluorescent defects in the solid object are also detected. A defect detection method based on the detection of the emitted light of 20 or the intensity distribution of the emitted light and the corresponding detection of the reflected light of the solid object or the intensity distribution of the reflected light is described in detail in DE 101 44 909 A1 and DE 10 2004 054 102 A1, the disclosure of which is hereby incorporated by reference. According to these methods, defects in solid objects (defects in plastic objects such as CD, DVD, etc.) can be detected by strong spatial resolution of reflection and emission. This makes it possible to detect optical giants n-inch (eg, eak) and small holes, as well as opaque or line dopants. By using the above-mentioned method, the method according to the present embodiment, it is possible to find the fluorescent defects and non-calender defects in the solid object in a particularly early manner. According to the present embodiment, the position of each non-fluorescent defect in the solid object: size, number and/or shape is detected by image processing. The position of a non-egg light defect, that is, it may be possible to detect the fluorescent defect: set = 10 - than #父' to obtain the type and cause of the defect, such as fluorescent defects such as gel particles, Probably in the case of the solid object production process for optical defects nn her. So get a better understanding. Such knowledge can be used to modify the cover system; the number of possible fluorescent or non-fluorescent defects can be reduced to the maximum, and the sub-solid object 15 is an immobilized strain according to an embodiment of the present invention. π戸 plastic film. The member is a plastic article or a % fluorescent-defective particle according to the embodiment of the present invention. Furthermore, the non-fluorescent defects are glass fibers or air dopants in the stains, small objects, and objects. Gel particles are *striae, plastic defects in the plastic particles before the production of plastic objects have appeared - medium defects, which are usually on the plastic object by injection into the industrial scale, the appearance of the particle t Particles can be made by ejecting plastic particles. Flow disturbance (also known as a spot). = (ie plastic objects) flow (1) smudges in plastic objects are particularly unwelcome because of the slender, relatively large defects. The small level is spherical, and the reason for the formation is that the plastic material is overheated (as during the production of the pellet). Therefore, small holes have also appeared in the plastic particles. It is gradually caused by the injection molding process, but it does not matter compared to the above: According to an embodiment, the area of the solid object is a segment exposure (ie, sub =), or a line exposure to the light of the first source or the light of the second source. According to this embodiment, the solid object is not Illumination, but by the first ancient = light or by the light of the first source, the segment is scanned (partitioned). This is the k-potential. Because the area segment illumination is used, it is possible to use a significant amount of strong source S] the entire image of the sorrow object or the camping light defect so that it can be processed by image processing. The size and power of the various sizes and the necessary resolution. Usually, the slave size is on the order of 10 mm x 10 mm (〇rder). According to another embodiment of the invention, a sample is further taken from a batch of plastic particles. This batch of plastic pellets is a plastic pellet that has been produced in one process and therefore uses the same process parameters. The solid object is produced from the sample, = not by the injection molding process. Fluorescent and/or non-fluorescent defects are also determined, and: the fluorescent or non-fluorescent defects specified in the 2 determines whether the solid object meets at least a given quality criterion. This batch of plastic pellets can only be released if the solid object meets at least one quality criterion. Sample According to the present invention, the quality control of the batch of plastic granules is carried out by taking particles from the granules to produce a plastic article. The granules are released based on defects in the plastics (plastics only meet the pre-existing quality acceptance criteria) (only if they have been rejected 20 5 15 20 200844425, after which they are approved for continued production). The plastic article thus acts as a prototype sample which is produced by trialing the particles. For paste, if the pellets are made to produce a cd substrate, the required CD substrate quality criteria are applied to the prototype. Only when the trial sample meets the quality acceptance criteria (4), it is considered that the difficulty is suitable for (3) the local product is the right one. If the automobile headlight cover is intended to be produced with the corresponding batch of particles, the prototype sample is applied with different quality acceptance. Guidelines, because in this case = can not be strict quality acceptance criteria. In this regard, the important thing is plastic

other hand, it may further cause defects in plastic objects. For example, the hot peppers and small holes have appeared in the (4) young children's towel. The gel causes flow disturbances, which are caused by the fact that the plastic objects are pulled away in the direction of flow. This kind of her gel particles, and its direction and (four) direction __. _ and ~, 疋 contains this method has its advantages · By producing a plastic test piece, the quality of the granules used to produce the plastic object is used as a test and thus it is possible to determine whether the granule is completely suitable as the desired plastic: To: test. Material - even before the pellet is delivered to the customer, or before the original item of 〃 2. Unsuitable granules are not used at all for the production of plastic plastics. Therefore, the cost of the Tim¥, the throne, or the delivery of the customer is reduced. In addition, the customer embraces the "reduction of the quality of the product". The result is from the high-quality product of the Qianshanling manufacturer. According to the embodiment of the present invention, it is in the form of a sheet or a plate. Produced in the injection molding machine = 2 machines, the plastic parts are generally based on the industrial scale == Advantages: Because of the plastic object, it is also produced in the same way as 11 200844425. Trial parts are also produced; they also contain similar defects caused by production because they use the same production process as mass production. The material so produced is thus particularly suitable for determining whether the particles used in its production meet the -^ quality criteria. On the one hand, plate-shaped or sheet-like plastic objects produce special sheets on the injection molding machine; on the other hand, the optical test process, plate-like, and sheet-like objects may be particularly successful. Furthermore, the lack of plastic objects is mainly due to the casting process of the injection molding machine, especially the contact surface = 3L /, the private 1 opening > tool surface. The geometry of the surface of the forming tool is a special embodiment of the use of plastic sheets as the geometry of the injection molding tool to determine whether the particles meet the _ set quality criteria and are therefore fully adequate. From/seeking; after injection of the spiral plasticization before the particles in the molding machine, the film is washed by a film (mmga (6) to produce a plastic object. The spiral plasticization of the particles is to promote the flow by injection molding snail = cut = enter 仃. Molding and (4) Forming drums contain = Table (4) layers, and may also consist of high-chromium alloys. In the case of -special real = thermal decomposition and / or cross-linking (Cr〇SSHnking) process can also be avoided. The applicable process parameters are the brothers, the pressure reaction can be controlled, and the control system includes the cycle time and the machine phenomenon (cavitation), and the w state sample injection molding is formed by a thin film: Note == The final shear stress. The shot (〇ff collapses a η_. The off-center material; = avoids the ^^ note and the material it promotes is deposited in the flow deviation region. Poor 12 200844425 The advantage is that After moving (4), the simple object passes through the wire, so that the prototype can be cooled by the hook. After the injection molding plate is cooled: it can be removed by using a suitable fixture system without touching the surface of the plate. For example, one that only touches the edge of the sheet Lateral jig. /..., 5. According to an embodiment of the invention, the deionized gas is sprayed onto at least one surface side of the solid object before the solid object is exposed to the first or first source of light. The side is discharged by a deionized gas. The dust is preferably removed from the surface. In addition, the suction surface corresponds to the suction of the dust particles. $有有- Benefits: When (4) the object is inspected by the above optical method At the time of defect 10, the dust particles appearing on the surface thereof are greatly reduced. According to the present invention, the projection surface of the surface of the maternity object exposed to light, light or non-light failure is also determined. In other words, the light emitted, emitted, and reflected by the object is detected by the camera. 2. The light spectrum of the image processing software is analyzed, and the entire projection of all glory or non-fluorescent defects is detected. The district can also be determined. Therefore, the quality acceptance criteria can indicate all the fluorescent or non-fluorescent light related to the size of the surface of the plastic object, and the maximum allowable total projection area (for example: Qian Qianguang or (4) The maximum allowable total projection area of the defect is equal to the jump of the surface of the plastic object being inspected. If all, the total projection area of the light or non-fluorescent level is smaller than the total projection area of the largest material, the first batch is again. It is: only the entire projection area of all glory or non-glory defects (not the projection area of each defect) is used to determine whether the plastic object meets the quality criterion. If compared to the projection area of each defect, the defect shadow area is 13 200844425 According to the embodiment of the present invention, the quality criterion indicates the absence of _, or the maximum material size of each touch (4), or the maximum number of (4) according to the embodiment of the present invention, a batch of plastic particles can be Among the quality categories - at least - the material is marked, : = class, and the batch of particles is approved as the highest quality category among several quality = criteria). Pay for it. Corresponding to σ σ For example, the -quality surface may be related to cd "say === qualitatively." - the plastic object produced by the particle sample, must be very south. If the _ object does not meet the quality acceptance criteria, the vines should not be released for the production of CD or DVD substrates. In the case of a car headlight cover, this plastic material is human soil; '''°, the substrate can be released to == its quality criteria. This kind of situation has its advantages: it is based on the age of the first == the age of the classification and thus 15 and is supplied to 7 households requiring a certain quality category (^ is divided into several quality categories, from < each household (corresponding to the quality of the particles) )): ί 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种 一种The image is distinguished by a fluorescent defect. The injection-first shape, size or color can be compared with the preferred embodiment of the present invention, and will be described in more detail below with reference to the drawings. Block diagram of the device in the transparent solid object. The device f(10) contains the optical test unit 1〇2 and the computer system 1〇4. The optical test 1G2 contains the first light source 1G6 and the camera (10). Optical test unit 1〇 2 The improvement includes a lens 110 and a chopper m. The computer system includes a micro-processor 125, a memory 116, a camera interface 118, and a display screen 12. The camera 108 is connected to the camera interface 118 via a wire 122, and thus the camera 108 The recorded image can be Transfer to the computer 1〇4, ... the solid object 124 is introduced into the optical test unit 1〇2 to check the defect. The light generated by the first light source 106 is projected through the lens 11〇 to the solid object I% of the Sichuan projection area Π6 The wavelength of the light generated by the first-light source 106 is selected to excite a luminescent defect (such as (4) i30, m, m) to cause it to emit light and glory. For example, the solid object 124 may belong to a plastic object. 132, 134 may be gel particles, and emit light when excited by ultraviolet light or blue light. In order to test the fluorescent defects of the plastic object, it is possible to use a mercury vapor lamp or a blue light ray as the first light source 1 〇 6. The camera 108 is associated with the first light source 〇6, and is located behind the solid object 124 as shown in Fig. 1. The filter 112 is applied to the emitted fluorescent light (the fluorescent light is the defect 132 in the first projection area). 126 is exposed to light and has high transparency. Filter n2 also has low transparency to the light generated by first light source 106. The image of defect 132 is thus fully recordable by camera 108, independent of the first source 1 〇 6 shots of light The solid object 124 can be displaced along the y-axis (refer to the coordinate system 128). The light source/camera system (including the first light source 106, the lens 11 〇, the filter 112, and the camera 15 200844425 108) can be displaced on the x-axis (Refer to the coordinate system 128) such that the projection area 126 migrates over the entire solid object 124, and the fluorescent light emitted by the defects 130 and 134 can also be recorded. Dust particles deposited on the solid object 124 (such as dust particles 136 and 5) 138) Fluorescence is also emitted. Fluorescent dust particles can also be detected by the camera 1〇8. The filter 112 is placed in such a manner that fluorescent light from the dust particles can pass therethrough. Images recorded by camera 108 in projection area 126 can be fed to the computer via wires 122 and 71. The microprocessor I 〗 # executes the computer program product 140 to process the image. The computer program product 14 is permanently stored in the memory 1 〇 116 and has been loaded into the microprocessor 114 prior to execution. The computer program product 140 combines the image produced by the projection area 126 on the solid object 124 to form an image 142 of the solid object 124 and is displayed on the display screen 120. The computer program product 140 also performs image processing of the image 142. The dust particles 15 I36 and 138 can thus be distinguished from the defects 130, 132, 134 based on their shape. For example, if the solid object 124 is a plastic object and the fluorescent defects 13〇, 132, and 134 are gel particles, the shape is a typical spherical shape. Therefore, these defects appear as circles in the image 142 because the camera records the projection of the solid object 124 on the coincident plane. On the other hand, dust particles such as dust particles 136 and 138 tend to be blurred and larger than defects. Dust particles 136 and 138 also generally emit fluorescence in a different color than the absence of 130 130 and 134. Fluorescent discs from dust particles may have different fluorescence from defects ~ such as in color chromaticity (c〇1〇r let "^ and / or color intensity (intensity) and / or color saturation (satumti〇n) 200844425 Dust particles and fluorescent defects are also beautiful 1 Figure 2 shows the flow chart, the steps of the method of defects in the fasteners. Two ^ = t clearly used ^ ^ measured in the solid light of the first source of light. The 2G2 7 'solid object is exposed to the defect detected by the second light source exposed to the first source light and/or the fluorescent light emitted from the solid object. Step 204 is performed on the dust particles deposited on the object based on the dust particles emitted by the object. The shot is printed on the object. V is small or color, and the fluorescent defect is shown in Figure 3. The second image is taken in the optical test unit 1G21'. The second projection area 152 of the solid object 124 is illuminated by the light source m. The camera system (including the light source 144 and the cameras 146, 148 and 15) can also be turned on. X-axis displacement (signature coordinate system 128). Plastics It can be displaced along the y-axis, so that the projection area I52 migrates over the entire object m, and the latter can be displayed as a whole. The light reflected by the solid object 124 is detected by the camera 146, and it is detected by the solid object 124. The light emitted and scattered by the defects of the plastic object 124 is detected by cameras 148 and 150. Camera 148 is located in the field of view of light source 144, while camera 150 is located in the dark field of light source 144. 200844425 The partial resolution detection signals of the machines 146 and 150 (which can also use the camera 148) make it possible to detect non-fluorescent defects in plastic objects, in particular including position, shape and size (for example, DE 10 2004 054 102 A1). Figure 4 shows a block diagram of a device for controlling the quality of a batch of particles. 5 Apparatus 400 comprises an injection molding machine 402, a die 404 and a cooling stretcher 4〇6. The controlled device 400 also includes means 408 for generating a deionized gas. The device 400 also includes an optical test unit 102 (shown in Figure i or Figure 4 and computer system 104 (shown in Figure 1). ', Sample 416 Taken from a batch of positive The granules of the tube are fed to the injection type machine to produce a plastic object (ksk) made of the sample. The injection molding machine 4〇2 contains a film washing system 41〇 and a connection (ship) 412 The data acquisition system 412 ensures that the temperature of the body and the tool is within the material=temperature range and is in the thermal decomposition or cross-linking process, and the pressure reaction may be the cavitation acquisition system 412 also controls the washing of the town, the first Baotong). _ The rate of the shell. The injection molding of the plastic is carried out by the injection system 410 into the mold, so as to avoid the flow deviation and the injection method through the direct cooling flow channel. Tool cavity is made up of at least two side modes::: move! The material contributed by the difference zone is from 5 to 1 mm (from 丨 to 4, ..., 70%, the wrong way is to produce a wall thickness of mm (4). It is better to 3. 0 mm == flow length by The plastic article 422 can be removed by the injection molding machine (for example, by loading and unloading the 200844425 tool) without damaging the surface of the plastic article 422. The mold residue is separated from the plastic article 422 by the mold 4〇4. The plastic article 422 is thereby cooled 406. Before the plastic article 422 is transported to the optical test unit 1〇2, the gas is sprayed onto at least the side surface of the plastic article 422. For this purpose, for the purpose of deionizing the gas The means tears a fan 414. The surface of the plastic object 422 is sprayed through the fan 414; and the dust is removed from the surface. After the surface discharge, the result is that the second ale particles are adsorbed to the plastic. The object 422 is far less than the previous level. 15 The plastic object 422 is thus transported to the optical test unit 1G and appears to be exposed to light from the first source, 106, and the plastic object is lacking light (as long as such defects occur and can emit glory ). The two objects in the material are especially likely to be gel particles, because these particles are generally granulated. It is inevitable that the gel particles become defects in plastic objects, but they are also Scars. The direction of expansion of the marks is constant and the machine in the injection molding machine is about the direction of the machine (with a difference of 15.). During the casting of plastic objects, when the direction of the slap is pulled, the smear is formed. The palpitations are 3 spin particles. The dust particles are also exposed to the first light source 2:: fluorescing. However, due to the use of deionized gas, the dust particles 2 should be minimized. All the flaws in the towel 'because it essentially ensures that there are no defects hidden by dust particles., , = (10) (4) _ contains (4) secret traps and s light dust her image of the object 116. The camera signal is via the camera interface (not Display) Supply = 20 200844425 Computer System 104. The computer program product 140 has an image processing component 42. By the image processing component 420, the fluorescent defects of the image of the plastic object are obtained from the plastic object 422 or the camera 108 and The particles can be detected and distinguished from one another. Furthermore, the size and shape of each of the five fluorescent defects can also be determined by the image processing component 42. & the image processing component 420 can also determine the fluorescent defects in the plastic object 422. The number of products is 418. The predetermined quality criteria 418 is also integrated into the computer program product. The computer program product 140 is based on the fluorescent light found by the image processing component 42 to determine the plastic object 42. Compliance with the quality criteria 418. For example, the 'Quality Criterion 418' of δ can indicate that a fluorescent defect having a size (projection area) greater than 1 〇〇 square micron may be present in a plastic object. If the defect is greater than (10) square micrometers by the image processing component 420, the batch of particles will not be dispensed. This can be used by the computer program product 14G via the display screen W to refer to FIG. 1) to issue the corresponding information (4) Ren (four) effect. If no defects larger than 100 square microns are found, the batch of particles can be released; for example, the computer program product 140 sends a corresponding signal to the homework operator. Furthermore, non-fluorescent defects such as smudges, small holes and glass = dimensional in plastic articles 422 can also be made. To this end, the optical test 102 of FIG. 3 also includes a second source 144, and cameras 146, 148, and 15A. = Light source U4 emits light in the visible range of money, and the intensity of the reflected or transmitted domain is measured by the local resolution (lGeally coffee (four)), which is measured by cameras 146, 148, and 150. The size, position and shape of the defect can thus be determined by the intensity distribution of the reflected or emitted light (eg, de 20 200844425 10 2004 054102 A1 and DE 101 44 909 A1). The information thus obtained can be matched to one or more defined The quality criterion (also related to non-fluorescent defects) results in a decision on the release of the batch of particles. 5 10 15 20 Figure 5 is a flow chart showing the steps of the method according to the invention. A sample is taken from a batch of particles. A transparent plastic article is produced from the sample in step 502. In step 504, the transparent plastic article is tested for presence or absence of a glare defect, and may also be selected for testing for presence or absence of a fluorescent defect. In 〇6, it is determined whether the plastic article meets the given quality criterion based on the defect. If this is the case, the batch of particles is released in step 508. As determined in step 506 If the object does not meet the quality criteria, then the quality of the granules is classified in step 51. 'The quality criteria are not fully met, so the batch of granules is not released. Figure 6 shows a table in which the plastic object occurs. The defects are classified as follows. The plaque is a flow disturbance, and when the plastic sheet in the injection molded article is pulled in a certain distance, the H: and the total enthalpy contains the gel particles and their direction and flow. The direction is the same. The visibility of the spot is from 10 to 200 microns. 〇·2 to 10 mm. + The length of the spot in the moving direction - the gel particles are the material of the gel-like material. When the light and non-fluorescent gel particles are different from the plastic or blue wavelength range n (four), the object particles are exposed to ultraviolet light for a length of about 10 to 200 microns.

Glass fibers and air bubbles may also occur in plastic objects. They are less related to the above defects. Glass fibers are cylindrical and bubble, and the length is 1〇 to 8 (9) microns (mainly 30 to 500 microns), while the diameter It is from 1 〇 to 5 〇 microns (mainly 10 to 20 microns).
