  However, in the above-mentioned engraving technology by sandblasting, a large amount of dust is generated, resulting in environmental pollution, and the engraved identification symbol tends to be unclear, resulting in poor finish accuracy. There was a problem.

  The present invention has been devised in view of overcoming the above-mentioned problems, and it is possible to reliably prevent air pollution caused by dust, and to provide a glass marking laser marker and a glass marking method in which a car body number and the like by marking are clearly finished. The purpose is to provide.

(1) In order to achieve the above object, the present invention adopts the following configuration. That is, the present invention is a glass marking laser marker for marking an identification symbol such as a vehicle body number on a glass surface by irradiating a carbon dioxide laser on a glass surface of a vehicle front windshield, door windshield, rear windshield or the like. The laser marker for glass marking is characterized in that the main body of the laser marker is suspended from the hand portion of the balancer via a ball joint.

  According to the present invention, when a laser marker body having a weight of 16 kg to 20 kg is suspended from a balancer, the laser marker body can be freely moved to an appropriate position by swinging around the ball joint. For this reason, it is possible to easily move and approach the glass of the target vehicle (automobile) to be engraved with the laser marker main body without requiring much human power, and to adjust the positioning. As a result, the marking work by the laser marker can be easily performed.

  (2) The present invention is also the glass marker for glass marking according to (1), wherein the ball joint is attached between a support mechanism provided in the laser marker main body and the hand portion.

  According to this, since it comprised so that a ball joint might be attached to the support mechanism with which the laser marker main body was equipped, the laser marker main body can carry out load distribution and can be pivotally supported by a ball joint. For this reason, it is possible to avoid an excessive external force from concentrating on the laser marker main body, and to suppress deformation and damage of the laser marker main body.

  (3) In the present invention, a swing feed mechanism is provided between the laser marker body and the support mechanism, and the laser marker body can be angularly displaced with respect to the support mechanism by the swing feed mechanism.

The laser marker body is interlocked by driving the worm wheel, and the laser irradiation method can be adjusted and set. Therefore, a fine adjustment of the laser irradiation direction can be easily and easily performed by a swing feed mechanism composed of a worm and a worm wheel, and a laser marker for glass marking with good operability can be obtained.

  (5) In the present invention, any one of the above (2) to (4) is characterized in that a stopper means for restricting a swing angle of the laser marker body is provided between the laser marker body and the support mechanism. It is a laser marker for glass markings described in 1.

  According to this, even if the laser marker main body is adjusted to the maximum angle by the swing feed mechanism, the laser marker main body is inadvertently placed on the balancer hand part because the maximum tilt angle of the laser marker main body is regulated by the presence of the stopper means. Interference can be avoided and damage to the laser marker body can be prevented beforehand.

  (6) The present invention is the laser marker for glass marking according to any one of (1) to (5), wherein the laser marker main body is equipped with a suction cup that can be adsorbed to the glass surface.

  According to this, by adsorbing the suction cup to the glass surface, the laser marker main body can be reliably positioned and fixed to the glass, and the marking accuracy can be improved.

  (7) The present invention is also the glass marker for laser marking according to (6), wherein the suction cup is adsorbed to the glass surface by an air suction force.

  According to this, since the suction force of air acts on the suction cup, the suction force can be increased, and the positioning of the laser marker body with respect to the glass surface can be performed more satisfactorily.

  (8) The present invention is also characterized in that a screw feed mechanism is provided between the suction cup and the laser marker body, and the suction cup slides relative to the laser marker body via the screw feed mechanism. The laser marker for glass marking according to (6) or (7).

  According to this, since the position of the suction cup can be slid and finely adjusted by the screw feeding mechanism, the laser marker main body can be easily positioned with respect to the glass.

  (9) The present invention is also a method of marking glass using the glass marking laser marker according to any one of (1) to (8), and after attaching a tape to the glass surface to be marked. The glass marking method is characterized in that the carbon dioxide laser is irradiated from above the tape.

  According to the present invention, the dust generated when engraved by the laser marker main body is not dissipated to the outside because the engraved portion is covered with the tape. As a result, it is possible to reliably avoid environmental pollution due to the dust of the engraved glass.

  According to the present invention, it is possible to prevent environmental destruction due to dust dissipation such as sand and glass as in the prior art described above, and the operability of the laser marker body is excellent, and the laser marker body is easily and reliably positioned on the glass surface. Therefore, the stamped identification symbol is clearly stamped, and as a result, a laser marker for glass stamping and a glass stamping method having high stamping accuracy not found in the prior art can be obtained.

  Hereinafter, embodiments of a laser marker for glass marking and a glass marking method according to the present invention will be described in detail with reference to the drawings. 1 is a three-side view of a laser marker body, FIG. 2 is an external view of a balancer for suspending the laser marker body, FIG. 3 is a front view of the laser marker body with a support mechanism and a ball joint attached, and FIG. 4 is a right side of FIG. FIG. 5 is a cross-sectional view taken along the line V-V in FIG. 3, with the swing feed mechanism and the screw feed mechanism omitted, and FIG. 6A is a left side view of FIG. ) Is a cross-sectional view taken along line VI-VI in (a). In addition, about the laser marker main body in FIGS. 3-6, in order to avoid the complexity on a figure, detailed illustration of the external shape was omitted.

  As shown in FIG. 1, the laser marker main body 1 has a housing having a substantially quadrangular prism shape, and a laser irradiation mechanism is built in the housing. A controller (not shown) and a monitor for a personal computer are connected to the laser marker main body 1, and a marking process based on the vehicle body number is performed while monitoring, and the glass to be marked is marked by the laser irradiation. The glass stamping system to be applied is installed. The laser marker main body 1 itself has a mode in which a pulse laser using carbon dioxide gas as an oscillation medium is irradiated as described in Patent Document 2 described above. Reference numeral 2 denotes a laser transmitting glass provided in the head portion of the laser marker main body 1, and reference numeral 3 denotes an air flow for sucking or discharging external air to the inside by a fan built in the laser marker main body 1. Each mouth is shown.

  Since the laser marker main body 1 has a weight of 16 kg to 20 kg and is a heavy object, the well-known balancer 4 shown in FIG. The balancer 4 is, for example, a scalar-type universal link device driven by compressed air. The balancer 4 has a movable upright column 4a and a parallel link mechanism that swings in the range of an angle θ within the vertical plane on the column 4a. A first link portion 4b, a second link portion 4c that can be swiveled within a plane within a range of, for example, 320 °, and a free end of the second link portion 4c at the tip of the first link portion 4b; The hand part 4d as a 3rd link part which turns in the range of 400 degrees within a plane is comprised.

  The lower end of the hand portion 4d is suspended by being coupled to a support mechanism 6 (described later) attached to the outside of the laser marker body 1 via a ball joint 5 as a universal joint. Thus, the operator can be formed as one of positioning means for bringing the laser marker main body 1 close to the desired glass to be engraved by grasping and operating an appropriate portion of the hand portion 4d.

  As shown in FIGS. 3 to 5, the support mechanism 6 is an aluminum plate that is fastened to the upper surface of the laser marker main body 1 by bolts and has a gate-shaped cross section by bolting a side plate portion 6 a 1 to a part thereof. The first substrate 6a made of a metal and the second substrate 6a made of a gate-shaped aluminum plate disposed outside the side plate portion 6a1. On both sides of the second substrate 6b, shafts 7a and 7b penetrating the second substrate 6b are fixed to the first substrate 6a. Thereby, the laser marker main body 1 integrated with the first substrate 6a is pivotally supported so that the shafts 7a and 7b can be swung with respect to the second substrate 6b.

  On the other hand, as shown in FIGS. 3 and 4, a swing feed mechanism 8 is provided between the laser marker main body 1 and the support mechanism 6 to perform the angular positioning of the laser marker main body 1 while finely adjusting the swing. Specifically, the oscillating feed mechanism 8 is engaged with a worm wheel 8a fixed to a shaft 7a protruding outward from the second substrate 6b so as to be integrally rotatable with the worm wheel 8a, and is attached to the second substrate 6b. The worm 8b and the operation handle 8c provided at the shaft end of the worm 8b are formed. By rotating the operation handle 8c, the worm 8b is driven, and the worm wheel 8a meshing with the worm 8b is driven to rotate. As a result, the laser marker main body 1 is integrated with the first substrate 6a and is angularly displaced in the directions of arrows A and B in FIG. 3 around the shafts 7a and 7b so that it can be oscillated.

  Stopper means 9 is provided between the laser marker main body 1 and the support mechanism 6. Specifically, as shown in FIG. 7, the stopper means 9 is formed by plate members 9a and 9b having a semicircular shape as a basic form, and there is an arcuate groove (hereinafter referred to as an "arc") about the shaft 7a. 9c) is provided, and is fixed to both side plate portions 6a1 of the first substrate 6a so as to be inclined backward by a predetermined angle as shown in FIG. 3 by fasteners such as bolts (not shown). In addition, the code | symbol 9d of FIG. 7 shows the fastening hole for the said fasteners.

  Further, as shown in FIGS. 3 and 4, the clamp lever 9e is screwed onto the second substrate 6b, the arc groove 9c is loosely inserted, and the tip thereof abuts on the side plate portion 6a1. Therefore, when either end of the arc groove 9c engages with the clamp lever 9e, the maximum tilt angle in the arrow A direction and the maximum tilt angle in the arrow B direction shown in FIG. The laser marker main body 1 is prevented from being damaged due to inadvertent contact with the second substrate 6b. Further, by tightening the clamp lever 9e, the laser marker main body 1 is positioned and fixed at the current swing angle of the laser marker main body 1 that has been pivotally fed, thereby forming a single positioning means that can perform the marking operation. Become.

  Next, positioning means using a suction cup, which is another feature of the present embodiment, will be described with reference to FIGS. 3, 5, 6, 8, and 9. An aluminum fixing plate 11 shown in FIG. 8 is fixed to an end portion of the support mechanism 6 reaching the head portion of the laser marker main body 1 by a bolt (not shown). A slide plate 12 that slides in the vertical direction is attached to the fixed plate 11. The fixed plate 11 is formed with a substantially rectangular bottomed recess 11a, and a female screw portion 13a, which is an element of the screw feed mechanism 13, is fixed thereto by bolting. Further, slide rails 11b having a concave cross section in the vertical direction are provided on both sides of the front side of the fixed plate 11.

  The slide plate 12 is formed with a rectangular hole 12a having substantially the same size in the bottomed recess 11a at a position corresponding to the bottomed recess 11a, and the male screw 13b is screwed into the female screw 13a. It is designed to make it easier to work for. A slide guide 12b that engages with the slide rail 11b is provided on the back surface of the slide plate 12 in the vertical direction, and a male screw portion 13b that is an element of the screw feed mechanism 13 is provided between the pair of upper and lower bearings 13c. It is pivotally supported and screwed into the female screw portion 13a.

  A trumpet-shaped vacuum pad, that is, a suction cup 10 is attached to the front side of the slide plate 12 via a bracket 10a. A negative pressure by a vacuum pump (not shown) is applied to the suction cup 10 to induce a suction force to the glass to be engraved. In addition, the code | symbol 12c of Fig.9 (a) shows the screw hole for attachment of the slide guide 12b.

  As a result, the slide plate 12 can be attached to the fixed plate 11 so as to overlap, and the knurled handle 13d at the upper end of the male screw portion 13b is rotated, whereby the slide plate 12 is fixed to the fixed plate 11, that is, the laser marker main body 1. Therefore, one positioning means is formed by adjusting the position of the suction cup 10.

  Thus, the laser marker body 1 to which the support mechanism 6, the swing feed mechanism 8, the screw feed mechanism 13, and the suction cup 10 are attached is connected to the balancer 4 via the ball joint 5 as shown in FIG. 2 and the support mechanism 6. A glass marker laser marker is provided on the hand portion 4d.

  Next, a glass marking system that drives and controls the glass marking laser marker will be described. FIG. 11 shows a menu screen of this glass marking system. When a personal computer (not shown) is activated, the menu screen is automatically displayed, and each instruction is waited for. By pressing one of the menu buttons, the process displayed on the button is executed.

  When the glass (vehicle glass) marking button is instructed, the screen of FIG. 12 is displayed, and the glass marking process is actually performed based on the registered classification data. That is, on this screen, engraving locations corresponding to all the glasses from the front glass to the rear glass are displayed. Further, when the operator barcode is read by the barcode reader, the worker is set. When the work slip barcode is read by the barcode reader, the marking information is set, and the marking instruction is waited. When each data in the selection is set, marking information is set manually, and a marking instruction is waited. When the excitation ON button is pressed, the laser marker main body 1 is excited, and when the excitation OFF button is pressed, the laser marker main body 1 is released from the excitation, and the menu button returns to the menu screen of FIG.

  When the single operation button is pressed on the menu screen, the screen shown in FIG. 13 is displayed, and the glass marking process can be performed by setting the marking information independently. That is, each piece of data within a single condition can be input to set marking information. When the data transmission button is instructed, the input marking information is transmitted to the laser marker main body 1 to enter the marking waiting state. Press the condition edit button to edit and register the marking conditions. When the excitation ON button is pressed, the laser marker main body 1 is excited. When the excitation OFF button is instructed, the laser marker main body is deactivated. When the menu button is pressed, the menu screen is restored.

  When the aggregation button is pressed on the menu screen, the screen shown in FIG. 14 is displayed, and performance information aggregation processing is performed. That is, when the aggregation date is set, the performance information within the set date is displayed. When single tabulation is checked, the performance information by itself is also displayed. By instructing the external save button, the save information is set in the text format by setting the save destination, and when the menu button is pressed, the menu screen is returned.

  When the standard / maintenance management button is instructed on the menu screen, the screen shown in FIG. 15 is displayed and the standard setting necessary for the glass engraving is performed. In other words, when the edit button for the marking condition is designated, the conditions for each glass position are set. When the edit button for the marking order is designated, the marking order can be set. By pressing the operator's edit button, the worker information If you press the menu button, you will return to the menu screen.

  When an unillustrated basic condition tab on the screen of FIG. 15 is designated, the screen shown in FIG. 16 is displayed, and each instruction is awaited. That is, when a file number is selected, the stored basic conditions are recalled and displayed. Information such as laser power, scan speed, and transmission frequency can be set in this basic information. Therefore, for example, the laser irradiation conditions differ between the case of a windshield glass using laminated glass and the case of a glass other than the windshield glass using tempered glass, so the laser output and irradiation time depend on the glass structure. The specifications of the laser irradiation can be changed appropriately.

  Thus, when the transfer button is instructed, the set basic conditions are transmitted to the laser marker body, and when the call button is pressed, the basic information of the file number is received and displayed from the laser marker body, and when the save button is pressed, it is currently displayed. Save basic information and press the menu button to return to the menu screen.

  When a data storage tab (not shown) on the screen of FIG. 15 is designated, FIG. 17 is displayed and each instruction is waited for. In other words, when a backup button is specified, data is stored in the data storage location, when a restore button is specified, data is listed from the storage location, and when the storage location button is specified, the storage location can be changed and the menu button is pressed. And return to the menu screen.

  A procedure for marking the vehicle body number on the glass of the automobile 14, for example, the windshield 15, using the glass marking laser marker will be described. The hand portion 4d is held and the laser marker main body 1 is moved so as to approach the glass 15. A transparent tape 16 is attached in advance to a corresponding portion of the glass surface to be engraved as a setup.

  Considering that the windshield 15 is inclined while having a curved surface, it is necessary to confirm and adjust the printing (engraved) position and focal length. For this purpose, the laser marker body 1 is moved closer to the glass while being adjusted to an optimum position. That is, the angle of the laser marker body 1 suspended from the balancer 4 is adjusted with respect to the support mechanism 6 by the operation handle 8 c of the swing mechanism 8. Further, the suction cup 10 is positioned while being adjusted by operating the knurled handle 13d of the screw feeding mechanism 13. Optimum fine adjustment of the print position and focal length and confirmation work are performed while trial and error of such operations. When the optimum position is determined, the suction cup 10 is attracted to the windshield 15 and the laser marker body 1 is positioned and fixed.

  Since the personal computer is in an activated state, for example, when the glass marking button is designated on the menu screen of FIG. 11, the marking location displayed on the screen of FIG. 12 is designated, and the excitation ON button is designated, the laser marker body 1 is displayed. Excited and engraved. Thus, the marking process routine of the glass marking system is executed, and the car body number is stamped on the surface of the glass 15 by performing the marking work. Glass particles generated in the stamping operation can be collected by adhering to the adhesive surface of the covered tape 16.

  According to the present embodiment, unlike the conventional glass stamping by sandblasting, the car body number is stamped on the glass by the carbon dioxide laser, so that environmental pollution due to dust can be reliably prevented, and the car body number is stamped with a clear finish. The vehicle can be effectively prevented from being stolen. Further, since the laser marker main body 1 is suspended from the balancer 4 for marking, the labor of the operator can be reduced and the marking work efficiency can be improved. Further, since the laser marker main body is suspended from the balancer via the ball joint, the laser marker main body can be easily positioned with respect to the glass, and further, the clamping positioning fixing function of the clamp lever 9e of the support mechanism 6 and the suction cup provided on the laser marker main body. Since it is equipped with 10 suction positioning and fixing functions, positioning and fixing to the glass can be performed accurately and reliably, and the marking accuracy can be increased. In addition, since it is possible to change the specifications of laser irradiation according to the type of glass, there is also an advantage that the marking accuracy can be maintained according to the glass. Further, since the laser marker main body 1 is coupled to the ball joint 5 via the support mechanism 6, it is possible to avoid the stress concentration of the hanging load that acts directly on the laser marker main body 1, and to protect the expensive laser marker main body satisfactorily. Moreover, since the laser marker main body 1 is supported by the stopper means 9 in a manner that avoids interference with the second substrate 6b of the support mechanism 6, damage to the laser marker main body can be suppressed.

  As described above, the glass marking laser marker and the glass marking method using the same according to the present invention have been described in detail by one embodiment, but the specific configuration is not limited to this one embodiment, and the gist of the present invention. Design changes and the like without departing from the scope of the present invention are also included in the scope of the present invention.

  That is, in the above embodiment, the number of the suction cups 10 is set to four. However, the number may be an appropriate number, and needless to say, the mounting position is not limited to the above embodiment.

  Further, regarding the stopper means 9, the clamp lever 9e is attached to the second substrate 6b side and the plate members 9a, 9b are attached to the first substrate 6a side. It is.

  Moreover, the laser marker main body 1 used in the above embodiment is an example, and a laser marker main body of a form other than this may be used.

  Further, the balancer 4 may be other than the structure used in the above embodiment.

  In the above description, the case where the car body number is stamped has been described as an example. However, other than the car body number, an identification symbol such as a name, initial, pen name, and other symbols may be used.

  The present embodiment can also be applied to glass for sunroofs, mirror surfaces of fender mirrors, door mirrors, room mirrors, vanity mirrors, etc., and glass for various lamps on the front, rear, left and right provided outside the vehicle.

  Further, the slide plate 12 is configured to be able to move the suction cup 10 by sliding relative to the fixed plate 11 by the screw feed mechanism 13, but in order to position and fix the movement of the suction cup 10, the side end face of the slide plate 12 is arranged. The relative sliding may be constrained by providing a screw with the screw and engaging the free end of the screw with the fixing plate 11. With such a configuration, relative sliding can be reliably restrained, and the suction cup 10 can be positioned more reliably.

  Further, a long hole (not shown) is formed in the slide plate 12 (or the fixed plate 11) in the vertical direction, and the screw member 12d shown in FIG. 6B facing the long hole is provided in the fixed plate 11 (or the slide plate 12). May be. By engaging the screw member 12d with the end portion of the elongated hole, the relative sliding amount of the slide plate 12 with respect to the fixed plate 11 can be limited.
