[0001] The invention relates to an automated method for cleaning vehicle components using solid carbon dioxide.

[0002] DE 199 26 119 A1 discloses a blasting tool for generating a jet of CO2 snow, comprising a first nozzle for generating a CO2 snow jet and a second nozzle for generating a support or pressure jet, wherein the second nozzle surrounds the first nozzle and is a nozzle for generating a supersonic jet. DE 199 26 119 A1 also discloses a device for treating, for example, cleaning, the surface of an object, such as a workpiece or a sample table, by blasting the surface with CO2 snow using such a blasting tool.

[0003] From DE 10 2004 033 728 A1 a method is known for processing an adhesive surface of a workpiece, wherein at least the adhesive surface consists of a metal or a metal alloy with a hydrated oxide and / or hydroxide layer, in which the adhesive surface is cleaned, in which the adhesive surface is activated, in which the adhesive surface is at least partially coated with an adhesion promoter and in which the adhesion promoter is chemically converted by a post-treatment.

[0004] DE 10 2005 002 365 B3 discloses a blasting method for cleaning surfaces, in which carbon dioxide is fed into a flowing carrier gas in a blasting line and converted into dry snow by expansion, the carbon dioxide being expanded into the carrier gas in a mixing zone in which the static pressure is less than 70% of the total pressure. Furthermore, DE 10 2005 002 365 B3 discloses a device for producing dry ice, comprising a feed line for carbon dioxide, a feed line for a carrier gas, a blasting line for a dry snow-gas mixture, and a mixing zone in which the carbon dioxide is expanded into the carrier gas, a static pressure of less than 70% of the total pressure being generated in the mixing zone.

[0005] DE 199 43 005 A1 relates to a method for cleaning the surface of a plastic object for pretreatment for a subsequent coating, in particular painting, process. This method uses at least one working robot equipped with at least one jet nozzle, by means of which pellet-like dry ice particles are blown onto the plastic object. The jet nozzle is automatically moved along the plastic object by the working robot during the blowing process to clean a specific surface section. The method is used primarily before coating large-area plastic parts, such as those used in the automotive sector in the form of bumpers, trim parts, or the like.

[0006] According to DE 199 43 005 A1, a plastic object to be processed is placed on a carrier at a loading point. A conveyor system moves and transports the carriers to a work area of ​​the robot. The jet nozzles are aimed directly at the plastic object, with the jet spacing approximately 20 cm. Maintaining this jet spacing relative to the plastic object is achieved by controlling the movement of the robot, which depends on the contour or shape of the plastic object.

[0007] DE 10 2004 033 728 A1 relates to a method for processing an adhesive surface of a workpiece made of a metal or a metal alloy with a hydrated oxide and / or hydroxide layer. According to DE 10 2004 033 728 A1, the method comprises the following steps: cleaning the adhesive surface, activating the adhesive surface, coating the adhesive surface at least partially with an adhesion promoter, and post-treating the adhesion promoter. Pretreatment can also be performed mechanically using CO2 blasting. In CO2 blasting, a blasting medium consisting of solid particles is directed at high speed onto the surface to be treated.DE 10 2004 033 728 A1 relates to a method for cleaning adhesive surfaces of vehicle components using solid carbon dioxide in an assembly line with several work stations, wherein the adhesive surfaces are cleaned with cleaning parameters specifically adapted with regard to an achievable adhesive force, a process time and / or an economic efficiency.

[0008] DE 10 2007 027 618 A1 relates to a method for pretreating polymeric surfaces of components to be painted, in which at least one polymeric surface of at least one component is cleaned within a pretreatment cell. According to DE 10 2007 027 618 A1, the surface is usually cleaned using carbon dioxide snow or carbon dioxide pellets. Components made of polymeric substrates, for example plastic bumpers for the automotive industry, are subsequently typically painted in a three-layer paint system. According to DE 10 2007 027 618 A1, a device for pretreating polymeric surfaces of components to be painted comprises a pretreatment cell in the form of a pretreatment booth and an infrared radiation device arranged outside the pretreatment booth. The component to be cleaned and flame-treated is first fed to the infrared radiation device via a carrier of a conveyor device.The component is then transported via the carrier to the pretreatment booth and to a cleaning device. This is followed by a position detection device and transport to a flame treatment device. After flame treatment, the component is fed to the painting process via the carrier.

In summary, and in other words, the invention thus results, among other things, in parametric quality optimization of a blasting process using dry ice for cleaning surfaces.

[0034] Exemplary embodiments of the invention are described in more detail below with reference to the figures. Further features and advantages will become apparent from this description.

[0035] They show schematically and by way of example: Fig. 1 shows a device for cleaning adhesive surfaces of vehicle components using solid carbon dioxide in plan view, Fig. 2 shows a device for cleaning adhesive surfaces of vehicle components using solid carbon dioxide in input side view, Fig. 3 shows a specific adjustment of cleaning parameters for adhesive surfaces of vehicle components made of a metal alloy, such as steel or aluminum alloy, and Fig. 4 shows a specific adjustment of cleaning parameters for adhesive surfaces of vehicle components made of a fiber composite material, such as carbon fiber reinforced plastic.

[0036] Fig. 1 shows a device 100 for cleaning adhesive surfaces of vehicle components 102 using solid carbon dioxide in plan view. Fig. 2 shows the device in the input side view.

[0037] The device 100 is part of an assembly line (not shown here) with multiple workstations. The device 100 is arranged in the assembly line in front of a workstation where an adhesive bonding process is performed.

[0038] The vehicle components 100 in the present case are vehicle bodies made of a metal alloy, such as a steel or aluminum alloy, or of a fiber composite material, such as carbon fiber-reinforced plastic, and at least partially coated and / or painted. The vehicle bodies each have a roof cutout, at the edge of which adhesive surfaces are arranged for gluing a panoramic roof into the roof cutout.

[0039] The device 100 comprises a chamber-like cleaning chamber 104 with side walls 106, 108, a ceiling 110, an entrance 112, and an exit 114. The entrance 112 and the exit 114 can each be closed by means of a high-speed roller door. The cleaning chamber 104 has a passive noise protection device with sound insulation and / or sound dampening means arranged on the side walls 106, 108 and the ceiling 110.

[0040] The device 100 has a transport device 116 with a conveyor and assembly supports for transporting vehicle components 102 through the cleaning chamber 104. The transport device 116 serves to transport the vehicle components 102 through the access 112 into the cleaning chamber 104, through the cleaning chamber 104, and out of the cleaning chamber 104 through the exit 114.

[0041] The device 100 comprises a blasting device 118 with a blasting nozzle 120 for blasting solid carbon dioxide onto the vehicle components 102. The blasting device 118 is, in this case, a dry ice blasting device. Dry ice blasting is a compressed air blasting process in which solid carbon dioxide, also referred to as dry ice, with a temperature of -78.9°C is used as the blasting medium. For cleaning, solid carbon dioxide particles are accelerated with the aid of compressed air as they flow through the blasting nozzle 120 and impact the adhesive surface to be cleaned at very high speed. This locally supercools and embrittles the layer to be removed. Subsequent carbon dioxide particles penetrate brittle cracks and suddenly sublimate upon impact. The carbon dioxide becomes gaseous and greatly increases its volume. In doing so, it removes dirt from the adhesive surface.The blasting device 118 is arranged on the transport device 116.

[0042] The blasting device 118 has a refillable and / or replaceable reservoir 122 for solid carbon dioxide. The reservoir 122 is replaceable to provide new solid carbon dioxide. The blasting device 118 has connecting hoses for supplying compressed air and solid carbon dioxide to the blasting nozzle 120.

[0043] The device 100 has a portal-like support device 124 through which vehicle components 102 can be guided for cleaning using the transport device 116. In this case, the support device 124 is designed as a frame made of aluminum profiles with a cross brace.

[0044] The device 100 comprises an industrial robot 126 for automatically guiding the jet nozzle 120. The industrial robot 126 comprises a manipulator and a control device and is programmable for cleaning adhesive surfaces of the vehicle components 102. The jet nozzle 120 is arranged on the manipulator and serves as an effector of the industrial robot 126. The industrial robot 126 is suspended from the support device 124. The industrial robot 126 is suitable for collaboration with a worker.

[0045] The device 100 has a charge dissipation device 128 with an ionizer for eliminating electrostatic charging of the vehicle components 102. The charge dissipation device 128 is arranged downstream of the industrial robot 126 with the blasting nozzle 120 in a transport direction a and serves to eliminate electrostatic charging of the vehicle components 102 caused by dry ice blasting. The ionizer is a controlled ionizer in which an electric field is controlled by measuring and deliberately adjusting a high voltage. The charge dissipation device 128 has a fan for blowing ionized air onto the vehicle components 102.

[0046] Adhesive surfaces of vehicle components 102 are each cleaned using specifically adapted cleaning parameters. The cleaning parameters are each adjusted with regard to achievable adhesive force, process time, and / or cost-effectiveness. To specifically adapt the cleaning parameters, one cleaning parameter at a time is first varied while the remaining cleaning parameters remain unchanged in order to determine an optimal parameter value in each case. A combination of cleaning parameters is then selected.

[0047] Fig. 3 shows a specific adaptation of cleaning parameters for adhesive surfaces of vehicle components made of a metal alloy, such as steel or aluminum alloy, with regard to a holding force.

[0048] In Fig. 3 The holding force achieved in each case is plotted in N / cm. To determine the holding force, a strip of material is applied to a cleaned adhesive surface under varying cleaning parameters and peeled off in a peel test, measuring the holding force.

[0049] First, a distance 200 of a jet nozzle from an adhesive surface to be cleaned is varied, while the other cleaning parameters remain unchanged. Subsequently, a movement speed 202 of a jet nozzle relative to an adhesive surface to be cleaned is varied, while the other cleaning parameters remain unchanged. Subsequently, a mass flow 204 of solid carbon dioxide is varied, while the other cleaning parameters remain unchanged. Subsequently, a pressure 206 for accelerating solid carbon dioxide is varied, while the other cleaning parameters remain unchanged. Subsequently, an angle 208 between a jet nozzle and an adhesive surface to be cleaned is varied, while the other cleaning parameters remain unchanged. The individual parameters can also be varied in a different order.

[0050] Reference line 210 shows the holding force achieved when cleaning an adhesive surface with isopropanol. It can be seen that higher holding forces can be achieved when cleaning an adhesive surface with solid carbon dioxide than when cleaning an adhesive surface with isopropanol.

[0051] Fig. 4 shows a specific adaptation of cleaning parameters for adhesive surfaces of vehicle components made of a fiber composite material, such as carbon fiber reinforced plastic, with regard to a holding force.

[0052] In Fig. 4 The holding force achieved in each case is plotted in N / cm. To determine the holding force, a strip of material is applied to a cleaned adhesive surface under varying cleaning parameters and peeled off in a peel test, measuring the holding force.

[0053] First, a distance 300 of a jet nozzle from an adhesive surface to be cleaned is varied, while the other cleaning parameters remain unchanged. Subsequently, a movement speed 302 of a jet nozzle relative to an adhesive surface to be cleaned is varied, while the other cleaning parameters remain unchanged. Subsequently, a mass flow 304 of solid carbon dioxide is varied, while the other cleaning parameters remain unchanged. Subsequently, a pressure 306 for accelerating solid carbon dioxide is varied, while the other cleaning parameters remain unchanged. Subsequently, an angle 308 between a jet nozzle and an adhesive surface to be cleaned is varied, while the other cleaning parameters remain unchanged. The individual parameters can also be varied in a different order.

[0054] A reference line 310 shows the holding force achieved when cleaning an adhesive surface with isopropanol. It can be seen that higher holding forces can be achieved when cleaning an adhesive surface with solid carbon dioxide than when cleaning an adhesive surface with isopropanol. Reference symbol
