Furthermore, the present invention provides an apparatus for positioning or aligning an object with respect to a support plate, or an apparatus for positioning or aligning with a support plate, which irradiates the object, in particular an object to be positioned At least one light source that illuminates at least one area of the marking and, in some cases, the light of the changed wavelength reflected from the object to be positioned and in particular reflected from the marking and / or the support plate The present invention relates to an apparatus provided with a recording device for evaluation, recording and possibly determining the position of an object based on the evaluated reflected light and / or correcting the position or alignment of the object. Furthermore, the invention relates to the use of such a method and such a device.

  A method and apparatus of the kind mentioned at the outset can be obtained, for example, from JP 06633030 or US Pat. No. 3,617,744. The purpose of these known configurations is to compare the image recorded by light or radiation with a changed wavelength with a mask, in particular to detect defects in already completed printed circuit boards. The purpose is to inspect wirings or circuits already formed on the substrate. No positioning or alignment of the printed circuit board using the recorded image is provided in any known embodiment.

  In the following, the present invention will be described in detail by way of example only, particularly in the context of printed circuit board manufacture or processing, but the present invention positions an object relative to a support plate or holder or support device, or A method and apparatus for alignment, in which light reflected from a support plate or support device supporting an object or object by the emission of light having different wavelengths is recorded in the recording device It should be noted that the present invention is widely applicable in methods and apparatus in which correction of the position or alignment of the support plate with respect to the support plate or correction of the position or alignment of the support plate with respect to the processing machine is performed. Such methods and apparatus can be used in a number of applications where very precise machining or machining needs to be applied to the workpiece, such as drilling, cutting, etching, etc. In addition, accurate alignment and positioning are essential, for example, in exposure and insertion operations.

  In the context of printed circuit board manufacture or processing, for example, to perform a drilling operation, in particular a laser drilling operation, a marking is provided on a printed circuit board or a substantially plate-like member comprising a plurality of printed circuit boards, It is known to make adjustments by moving a generally plate-shaped member to a processing station and displacing it with respect to a support plate or a holder or support device forming the support plate, for example, a computer-controlled drilling program For example, to connect individual components of the printed circuit board in further processing steps, to insert additional components, or to join various layers of the printed circuit board In order to form a plurality of holes in a printed circuit board, more generally a plate-like member, usually at least 2 It is known to be effected by providing the markings.

  To date, this type of alignment and positioning operation typically involves guiding or directing light, for example, a properly bundled light, onto an object to be positioned, such as a printed circuit board, in the area of marking, Light reflected from the printed circuit board, or generally reflected from the object to be positioned, or reflected from the support plate, for example, if there is a hole-like marking that completely penetrates the object to be positioned Is recorded in a recording device, and in some cases, automatic image processing is performed to determine the position or alignment of the object to be processed with respect to the support plate, and if necessary, subsequent processing operations such as drilling operations are performed. It includes setting or adjusting to a predetermined set value so that it can be executed with appropriate high accuracy.

  Known methods and apparatus for recording such reflected light to determine the position and alignment of an object to be positioned reflect on the object to be positioned, in particular a printed circuit board or a plate-like member comprising a plurality of printed circuit boards. If the surface is at least partly provided, the area around the marking of the object to be positioned will exhibit a bright color or white, for example, to provide sufficient contrast to the marking or in the case of through-hole markings. It has the disadvantage that it is difficult or impossible to provide a correspondingly good contrast to the supporting plate. This is because the light reflected from the reflecting surface of the object to be positioned (stray light) and the light reflected from the marking or the support plate located below the marking to form a reference for determining the arrangement or orientation of the object This is because it becomes impossible to distinguish between them with the required accuracy.

  In particular, in view of the fact that, for example, components that are partly very small in size must be subsequently connected or joined, so that the applied components or for example the holes to be formed must be provided with small dimensions. For example, in the context of the high precision required for the manufacture or processing of printed circuit boards, a correspondingly large proportion of the objects are adjusted particularly sufficiently accurately when using known methods and devices. As a result, it is expected that it will not be processed accurately as a result, and therefore the occurrence of defective products must be expected. Furthermore, a large misalignment or positioning error leads to production interruption in such cases, since the control mechanism normally stops production.

  The present invention thus avoids the above-mentioned problems in the method and apparatus of the kind defined at the outset, and the method and apparatus of the kind defined at the outset, in particular during the high-precision production or processing of objects, In order to reduce the proportion of processed objects that do not meet the requirements, i.e. the proportion of defective products, the positioning or alignment of the object with respect to or with the support plate, simplified or facilitated recording of reflected light and cases It is intended to be further developed with the intention that some can be executed with higher accuracy by evaluation.

  In order to achieve these objectives, the type of method defined at the outset basically means that the light used for irradiation is converted into light of different wavelengths by using a luminescent material in the area of the marking, It is characterized in that light of different wavelengths is selectively recorded in a recording device and evaluated in some cases. In contrast to known methods in which light reflected directly from an object, in particular a marking or support plate, is recorded and possibly evaluated, according to the invention, for the wavelength of the light used for irradiation, Light having a different wavelength or a changed wavelength, generally conversion to electromagnetic waves is achieved by using a luminescent or luminescent material in the area of the marking, after which it has this changed wavelength Due to the fact that only light is selectively recorded and possibly evaluated in the recording device, it is reflected from the object, for example in the area surrounding the marking, and the original light used to illuminate the object, in particular the marking. Light having a wavelength is not recorded in the recording device, and as a result, is positioned or aligned with respect to the support plate, or For at least one marking of an object that is positioned or aligned with a holding plate or holder or support device, the actual position or alignment is more accurately and possibly simplified by a method of recording and evaluation. It is guaranteed that it can be determined. By converting the light used to illuminate the marking area of the object into light of another wavelength by using light emission, i.e. fluorescent or phosphorescent material, alignment and positioning accuracy is increased, Thus, after this improved and more precise positioning and alignment, it is possible to machine the object to be machined with a correspondingly increased accuracy. As a result, machining defects due to inaccurate positioning or alignment or errors in the actual position and alignment measurement are greatly reduced or completely prevented for the object to be positioned, thus reducing the respective quality requirements. The percentage of processed objects that do not satisfy, i.e., the resulting defectives, is also reduced. Furthermore, problems related to work interruptions due to significant misalignment or misalignment can be avoided or eradicated. In addition, the method according to the invention also reduces the time required for alignment or positioning, so that the application of the method according to the invention results in an increase in efficiency or productivity. In fact, while reflected light may not be introduced into the recording and evaluation device, the light applied from at least one light source to the object to be positioned or aligned is either luminescent or fluorescent or phosphorescent It is essential for the method according to the invention that it is converted into another wavelength of light, generally an electromagnetic wave, and this other wavelength of radiation is subject to recording and possibly subsequent evaluation methods. It is.

  In order to facilitate recording and possibly subsequent, for example, in particular automatic image evaluation, according to a preferred embodiment of the method according to the invention, light having a predetermined wavelength is used to illuminate the object. It is proposed to convert this light into light having a wavelength different from the wavelength of the light used for irradiation by the luminescent material.

  In the context of the method according to the invention, according to a further preferred embodiment, a filter, in particular an optical filter, is placed in front of the recording device, so that a substantially unchanged recording device can be used in the light of the prior art. It has been proposed to tune the filter to the wavelength of the light at the changed wavelength, and such a filter allows simple, reliable and accurate tuning to the converted or changed wavelength. Furthermore, the use of such a filter makes it possible to prevent, for example, light of the original wavelength reflected by the object and possible stray light from entering the recording device in a simple manner. .

  Alternatively or additionally, stray light or reflected light of the original light used to irradiate the marking area can be recorded to accommodate a preferred further development of the method according to the invention. The recording device can be provided with a plurality of recording channels for light of different wavelengths, and the channel is selected according to the changed wavelength of light in the recording of reflected light and in subsequent evaluation in some cases be able to.

  In order to correspond to a further preferred development of the method according to the invention, a very simple marking configuration can be provided, for example, by forming the marking by a through-hole and providing the support plate with a layer of luminescent material. is there.

  Furthermore, in order to achieve the above-mentioned object, a device of the kind defined at the outset is basically light of a wavelength that has been changed relative to the wavelength of the light emitted to the object, which comprises positioning and / or Or a recording device that selectively records the light reflected by using a luminescent material in the marking area of the object to be aligned. As already mentioned above in the context of the method according to the present invention, the device according to the present invention selectively selects light with a changed or converted wavelength (the change in wavelength is realized by using a luminescent material). The recording of reflected light corresponding to the changed wavelength is prevented, and simple and reliable recording and evaluation of the position and / or alignment of the object to be positioned can be realized. become.

  In order to prevent stray light from entering and to provide a simple means for recording only light of a changed wavelength on the recording device, according to a preferred embodiment, the changed wavelength is placed in front of the recording device. It is proposed to position a filter, especially an optical filter, adapted to the light.

  Alternatively or additionally, the recording device further comprises a plurality of color channels for recording light of different wavelengths, in particular a camera, so as to correspond to a further preferred embodiment of the device according to the invention. Can be configured.

  According to a further preferred embodiment, possibly to correct the position or alignment of the object to be positioned that is required, the object to be positioned and / or aligned is displaced relative to the support plate or displaced together with the support plate.

  In the following, the invention will be described in more detail by means of exemplary embodiments schematically illustrated in the accompanying drawings.

1 is a schematic perspective view of a first embodiment of an apparatus according to the invention for carrying out the method of the invention. FIG. FIG. 2 is an enlarged partial sectional view of a region of marking of an object to be positioned or aligned for the embodiment according to FIG. In a view similar to FIG. 2, a cross section of a part of an embodiment of a variant of the device according to the invention for carrying out the method of the invention is shown. A diagram similar to FIG. 2 shows an embodiment of a further variant of the device according to the invention for carrying out the method of the invention.

  FIG. 1 shows a positioning or formation formed by a substantially plate-like member comprising a plurality of printed circuit board members schematically indicated by reference numeral 2 which is divided into individual printed circuit board members after processing and completion. 1 schematically shows an object 1 to be aligned. In the embodiment according to FIG. 1, the object 1 to be positioned and / or aligned has, for example, two markings 3 in the form of through-holes 3 as will be described in more detail with particular reference to FIG.

  Light is emitted from the light source 4 along the beam path 5 shown schematically to the marking or marking 3 region of the plate-like member 1 and will be described in more detail with reference to the following figures. As described above, since the luminescent material is provided in the region of the marking 3, light having a wavelength changed with respect to light emitted from the light source 4 along the beam path 5, generally, electromagnetic waves are represented by reference numbers. 7 is conveyed along the beam path 6 to a recording device, schematically indicated by 7. For example, an optical filter 8 is located in front of the camera 7. As will be described in more detail below with particular reference to the remaining figures, the optical filter 8 allows only light of a changed wavelength by the beam path 6 to enter the recording device or the camera 7 while marking 3 for example. Light having the same wavelength as that emitted from the light source 4 is prevented from passing through the filter 8.

  The recording device 7 performs an evaluation on the position and / or alignment of the object 1 to be positioned, for example an automatic image evaluation, in particular according to a signal received at the recording device 7, an evaluation and display device or unit 10. Are connected by a connection line 9 which is shown schematically.

  When the evaluation apparatus 10 detects a misalignment or a position error of the plate-like object 1 with respect to a predetermined value, for example, the plate-like object 1 is supported in the directions of arrows x and y according to an orthogonal coordinate system, A device 12 for positioning or displacing relative to the support device 13 is controlled by a control line 11 for positioning, for example in order to match the marking 3 to a predetermined set value in light of the exact placement and alignment of the object 1. Be controlled.

  Instead of this, or in addition to this, in the case of misalignment of the object 1, a device 14 for displacing the support plate 13 or the holder or the support device in the directions of the arrows X and Y is used for the subsequent processing steps. In order to enable accurate placement of the plate-like object 1, it may be controlled by the evaluation unit 10. Such subsequent processing steps can include, for example, laser drilling using drilling means not described in detail.

  In the embodiment according to FIG. 1, in order to achieve an accurate spatial positioning or alignment for the object 1 to be positioned, the second recording device 7, together with a corresponding second light source 4, for example a second located oppositely. The marking 3 can be provided. Alternatively, the recording device 7 is moved correspondingly into the area of the marking 3 and light having a wavelength changed or converted relative to the wavelength used to irradiate the object, in particular the area of the marking 3, in general, Specifically, recording may be performed again with electromagnetic waves.

  From the detailed description according to FIG. 2, it is clear that the marking 3 of the substantially plate-like object 1 to be positioned is formed by a through-hole. Furthermore, in FIG. 2, a support plate or holder or support device, also indicated by reference numeral 13, is provided with a layer 15 of luminescent material at least in the region of the marking 3 of the object 1 to be positioned. It is schematically shown that the light emitted from 4 along the beam path 5 is converted by the emissive layer 15 into different wavelengths of light by the beam path 16. This different wavelength light 6 passes through the optical filter 8 and enters the recording device 7 after appropriate selection of the optical filter 8. In contrast, constant wavelength light reflected from the surface of the object 1 along the beam paths 16 and 17 is blocked by the optical filter 8 and therefore cannot enter the recording device 7, and as a result, the recording device 7. The light entering the light source is light of a changed wavelength that is converted by the light from the light source 4 colliding with the luminescent material 15 located below the marking 3 along the beam path 5, i.e. the effect of stray light or It is ensured in a simple and reliable way that the influence of the reflected light does not affect the evaluation of the exact placement or alignment of the object 1 to be positioned.

  In this way, the light emitting layer 15 is simply provided so that the light along the beam path 5 having the original wavelength can be simply converted into the light of the beam path 6 having the changed wavelength. In order to reduce or eliminate the alignment, it is possible to realize a reliable and accurate positioning of the object 1 to be positioned.

  In this case, light emitted from at least one light source 4 corresponding to the beam path 5 to the object to be positioned is absorbed by the light emitting layer 15, and the light emitting layer 15 is generally light having a changed wavelength, Emits electromagnetic waves 6 and the radiation by the beam path 6 shown schematically is substantially recorded on the recording device, in particular after passing through the filter 8, and is possibly subject to further evaluation. It is essential.

  It is also possible to replace the fluorescent or luminescent layer shown in FIGS. 1 and 2 with, for example, a fluorescent or fluorescent colored film or foil, a polymer, or glass.

  FIG. 3 shows an alternative embodiment in which the light of the original or initial wavelength from the light source 4 following the beam path 5 is again applied to the area of the marking 19 to the substantially plate-like object 18. In the embodiment shown in FIG. 3, the object 18 to be positioned is formed by, for example, a multilayer printed board. As can be seen from FIG. 3, the marking 19 is formed by a depression or a dead hole provided in the surface of the object 18 to be positioned, and the multilayer object 18 to be positioned is also at the bottom of the depression or marking 19. The region includes a layer 20 of luminescent material, so that the incident light according to the beam path 5 is converted into light by the beam path 6, which also has a changed wavelength, generally electromagnetic waves, again with reference numbers After passing through the optical filter indicated by 8, it enters the recording device 7.

  As in the embodiment according to FIG. 2, the light reflected from the surface of the object 18 again along the beam path indicated by reference numerals 16 and 17 cannot pass through the filter 8 or at a greatly reduced intensity. Can only pass through and therefore cannot enter the recording device 7.

  Therefore, in the embodiment shown in FIG. 3, in contrast to the configuration according to FIG. 2, it is not necessary to provide a light-emitting layer on the support plate 13 or the holder or the support device.

  In the embodiment shown in FIG. 4, the object to be positioned, indicated by reference numeral 21, has a marking 22 formed on its upper surface with a luminescent material, which results in the previous embodiment. As is the case, the light emitted from the light source 4 along the beam path 5 is converted into light having a changed wavelength that also follows the beam path 6 after impinging on the emission marking 22, and this light is optical. After passing through the filter 8, it is also recorded in the recording device 7 and in some cases further evaluation is added.

  As in the case of the embodiment according to FIG. 3, no light emitting layer is provided on the support plate 13 in the embodiment according to FIG. 4.

  In order to position each plate-like object 18 or 21 with respect to the support plate 13 or with the support plate 13, the device 12 for displacing the plate-like object and / or the support plate 13 is also provided. Device 14 for displacing together with the object in the form of an evaluation device which, like the embodiment according to FIGS. 1 and 2, is configured to follow the recording device 7 of the embodiment according to FIGS. Can be connected to.

  Furthermore, in FIGS. 2 to 4, for the sake of explanation, each of the beam paths 5 and 6 may be used to increase the resolution of the area of the recording device 10, for example, in addition to the light source 4 indicated or presented. It has been shown that it is possible to provide at least one further light source, indicated by the additional reference number 4 '.

  Instead of the additionally shown light source 4 ′, for example, a plurality of light sources 4 ′ can be arranged in a substantially annular manner around the recording device or camera 7. With respect to such an arrangement, for example, an advantage over the non-central arrangement represented by FIGS. 1 and 2 is that the influence of the shadow is small, particularly in the annular arrangement of the plurality of light sources 4 ′.

  The light source 4 can be, for example, in the visible range, or in the UV or infrared range, preferably having a narrow spectral range, so that light having each of a well-defined color and wavelength is emitted. For example, it can be composed of a light emitting diode, a laser diode, various kinds of lamps, etc. combined with a color filter. A light source 4 having an appropriate wavelength and color can be selected in coordination with the luminescent material 15, 20 or 22 used to convert the wavelength of light used to illuminate the object 1 to be positioned.

  Utilizing the intrinsic fluorescence of the printed circuit board, generally the material of the object 1 to be positioned, in particular the polymer of the object 1 to be positioned, in selecting an appropriate electromagnetic wave, for example UV light Is also possible, which is particularly applicable to the embodiments according to FIGS. In the same way, it is also possible to apply the so-called inverse contrast to the embodiment according to FIGS.

  In coordination with the wavelength changed by the luminescent material 15, 20, or 22, the filter characteristics adjusted to the color of the light emitted by the luminescent material in the area of the marking 3, 19, 22 or to the wavelength after the change. A correspondingly tuned optical filter 8 is used, in particular the light from the light source 4 or 4 'is blocked.

  It is also possible to replace the optical filter 8 in which the recording device 7 is disposed adjacently with, for example, a recording device 7 having a plurality of color channels, for example, an RGB camera. , 20 or 22 can be distinguished or set by changing the wavelength or combination of channels of the recording device 7.

  Instead of a recording device or camera having a plurality of color channels, various types of cameras such as black / white CCD, CMOS, etc. can be used as the recording device 7.

  Furthermore, it is possible to use dichroic mirrors in the area of the recording device 7 and / or at least one light source 4.

  As shown in FIG. 1, for example when using an object 1 to be positioned comprising a plurality of printed circuit boards or printed circuit board members 2, a plurality of drill holes or passages or microvias are formed in the area of the individual printed circuit board members 2. For example, the processing of the printed circuit board 2 using a drilling device, in particular a laser drilling device, is performed after the positioning and alignment of the object 1 are completed. Alternatively or additionally, milling using at least one milling machine can also be used.

  Furthermore, there is a correspondingly accurate and highly accurate alignment and positioning of the object 1 to be processed, especially in the context of processing or manufacturing printed circuit boards, such as photo printing processes, masking processes, silk screen processes, exposure or insertion operations, etc. Other required manufacturing steps can be carried out in the same way.
