Description

Technical Field

[0001] This invention relates to a cleaning device and a cleaning method for cleaning parts, particularly vehicle body parts. Background Technology

[0002] Cleaning equipment for cleaning motor vehicle body parts is known in DE102009020114A1. In painting equipment used for painting motor vehicle body parts, this cleaning equipment is typically used to clean the vehicle body parts before the actual painting process, as contamination (e.g., dust) on the vehicle body parts can affect the paint finish. In practice, feather rollers (e.g., with emu feathers) and sword brushes have become particularly effective cleaning equipment because they provide both thorough and rapid cleaning. However, particularly when using feather rollers and sword brushes, it is impossible, or at least unsatisfactory, to clean sharp edges, although this may be necessary; for example, cleaning cannot be done along wet joints (e.g., sealing joints) where the parts are not yet completely dry. If the feather roller or sword brush enters a joint that is not yet completely dry, it can cause contamination of the cleaning equipment (e.g., feathers or bristles) and the parts, and / or damage to the joint. Furthermore, sword brushes are relatively expensive. Summary of the Invention

[0003] The purpose of this invention is to provide a cleaning device and method for cleaning components, particularly vehicle body components, which can perform sharp edge cleaning on vehicle body components, i.e., lateral cleaning along local areas of the component, especially areas where the surface is not yet completely dry.

[0004] The object of this invention can be achieved by the features of the independent claims. Beneficial developments of this invention have been disclosed in the dependent claims or can be derived from the following description of preferred embodiments of the invention.

[0005] The present invention relates to a cleaning device for cleaning components, preferably vehicle body components.

[0006] This cleaning device is specifically designed for cleaning parts laterally along wet, localized areas of components (especially stationary ones).

[0007] Cleaning equipment includes cleaning stations and conveying devices, which are used to transport components through the cleaning stations (e.g., continuously or sequentially).

[0008] The cleaning equipment also includes at least one first cleaning device for extensive cleaning of the components.

[0009] The first cleaning device may be part of an automated moving machine, such as a multi-axis robot, a top machine, and / or a side machine.

[0010] The cleaning equipment is particularly characterized in that it includes at least one multi-axis robot, which includes a second cleaning device for preferably cleaning sharp edges of the component, especially narrow-area cleaning. The multi-axis robot is particularly adapted to guide the second cleaning device laterally along a local area of ​​the component so as to clean the component laterally beside the local area. Preferably, the second cleaning device does not enter the local area.

[0011] A local area of ​​a component can be (in particular) a wet (e.g., damp) local area and / or a local area where the surface has not yet dried.

[0012] A localized area of ​​a component may be a joint where the surface is not yet fully dry (e.g., a sealed joint), particularly a wet joint. Alternatively or additionally, a localized area of ​​a component may also be a painted surface that is not yet fully dry.

[0013] The sprayed surface may include painted surfaces, sealing surfaces, heat-insulating surfaces, and / or corrosion-resistant surfaces.

[0014] The coating surface can include polyvinyl chloride, etc.

[0015] The second cleaning device can be a cleaning brush, especially a plastic cleaning brush.

[0016] The second cleaning device can be a cleaning roller (especially a plastic cleaning roller), with an outer diameter preferably less than 40cm, 35cm, 32cm or 29cm, and / or greater than 5cm, 10cm, 15cm or 20cm.

[0017] In particular, the second cleaning device may include, for example, cleaning filaments for cleaning sharp edges, preferably multiple (appropriately relatively long or relatively short) fibers, bristles and / or blades, preferably made of plastic material (e.g., plastic fibers, plastic bristles and / or plastic blades). Alternatively or additionally, the second cleaning device may also include a cleaning felt and a cleaning roller.

[0018] For example, fibers, bristles, or blades, or general cleaning filaments, can be relatively short, such as a maximum of 3cm, 2cm, 1cm, or 0.5cm, but they can also be longer.

[0019] The second cleaning device (preferably a cleaning roller) may be equipped with at least one lateral shielding device (e.g., a sidewall or a limiting disc) to prevent plastic fibers, plastic bristles, plastic blades, or general cleaning filaments from laterally deflecting (e.g., deforming) outside the shielding device and thus entering localized areas. For example, if plastic fibers, plastic bristles, plastic blades, or general cleaning filaments are subjected to the action of a component during cleaning, which may cause lateral deflection (e.g., deforming), this prevents them from entering localized areas outside the shielding device. In this way, sharp edges can be effectively supported and / or cleaned.

[0020] The second cleaning device may be equipped with lateral shielding devices on one or both sides.

[0021] For example, shielding devices can be made of materials that are elastically indeformable or have only minimal elastic deformation.

[0022] A multi-axis robot may include at least five or at least six axes of motion, and / or a second cleaning device mounted on the multi-axis manipulator.

[0023] The first cleaning device, especially for large-area cleaning, can be, for example, a rotating sword brush, a feather brush, a feather roller, especially an emu feather roller or a cleaning roller.

[0024] In an advantageous embodiment, the first cleaning device may be a first cleaning roller having a first outer diameter, and the second cleaning device may be a second cleaning roller having a second outer diameter, wherein the outer diameter of the first roller (preferably for large-area cleaning) may be larger than the outer diameter of the second roller (preferably for sharp-edge cleaning, particularly for small-area cleaning).

[0025] For example, the outer diameter of the first roller can be at least 1.5 times or at least 2.0 times the outer diameter of the second roller.

[0026] The second cleaning device may be a cleaning roller and includes a drive motor (preferably itself) for rotating the cleaning roller. Alternatively, the first cleaning device may preferably be formed as a cleaning roller and include a drive motor for rotating the cleaning roller.

[0027] For example, the drive speed of the drive motor of the second cleaning device may be greater than that of the drive motor of the first cleaning device, for example, at least 1.5, at least 2.0, at least 2.5 or at least 3.0 times greater.

[0028] For example, the cleaning speed of the second cleaning device is preferably higher than that of the first cleaning device (e.g., at least 1.5, at least 2.0, at least 2.5, or at least 3.0 times).

[0029] Therefore, when using the second cleaning device, its cleaning speed can be greater than that when using the first cleaning device (for example, the coefficient is at least 1.5, at least 2.0, at least 2.5, or at least 3.0 times).

[0030] In addition to multi-axis robots, cleaning equipment may also include at least one automated motion machine (e.g., having at least one, at least two, at least three, at least four, at least five, or at least six motion axes) that carries the first cleaning device.

[0031] Therefore, the first cleaning device is preferably carried by its own automatic motion machine (i.e., automatic motion machine), while the second cleaning device is preferably carried by its own mobile device (i.e., multi-axis robot).

[0032] The automated motion machine can be a multi-axis robot (e.g., having at least 4, 5, or 6 axes of motion) used to guide the first cleaning device to move rapidly along the part in order to clean the part.

[0033] However, automated motion machines can also include so-called top machines or side machines.

[0034] For example, cleaning equipment for cleaning components may include at least one top machine, which preferably has a first cleaning device and / or cleaning equipment may include a side machine, which preferably has a first cleaning device.

[0035] For example, the cleaning equipment may include at least one previously specified first cleaning device and / or at least one previously specified second cleaning device on each side of the conveying device.

[0036] Therefore, the cleaning equipment may include, for example, at least one automated moving machine (e.g., a multi-axis robot, a side-mounted machine, etc.) with a first cleaning device on both sides of the conveyor, at least one multi-axis robot with a second cleaning device, and optionally, for example, a top machine with a first cleaning device.

[0037] The multi-axis robot can laterally guide the second cleaning device along a local area, specifically preventing the second cleaning device from entering the local area. Alternatively or additionally, the multi-axis robot can also laterally guide the second cleaning device along a local area, where the lateral distance between the second cleaning device and the local area can be less than 2 cm, less than 1 cm, less than 0.5 cm, or less than 0.25 cm, or the lateral distance can be essentially 0 cm.

[0038] It is understood that in this invention, the first cleaning device also cleans the component, especially when the first cleaning device does not enter a localized area. However, the first cleaning device is configured for convenient large-area cleaning, and therefore, for example, it is not suitable for cleaning sharp edges. Therefore, the first cleaning device preferably cleans the component in an area sufficiently far from the localized area, for example, at least 2 cm, at least 3 cm, at least 4 cm, at least 5 cm, or at least 6 cm.

[0039] Therefore, the first cleaning device is particularly suitable for cleaning components, for example, when the lateral distance between the first cleaning device and the partial area is at least 2 cm, 3 cm, 4 cm, 5 cm or 6 cm.

[0040] The cleaning equipment may include control devices, particularly for automatically controlling a second cleaning device (e.g., its rotational speed and / or rotational direction) and / or a multi-axis robot to guide the second cleaning device to move laterally along a local area.

[0041] Therefore, for example, multi-axis robots can be adjusted and controlled, in particular, by control commands from a control device, to laterally guide a second cleaning device along a local area.

[0042] Control devices (such as control computing devices, computers, etc.) can be quickly connected to multi-axis robots and include a central control unit and / or a decentral control unit.

[0043] The control device may include a control computing device on which control programs for controlling a multi-axis robot may be stored, particularly for guiding a second cleaning device to move laterally and rapidly along a local area in a predetermined manner.

[0044] Within the scope of this invention, the control device and its functions can be distributed across multiple different hardware components.

[0045] It should be noted that cleaning of components can be internal and / or external.

[0046] It should also be noted that the first cleaning device is particularly suitable for area cleaning, such as cleaning the top and / or one or more sides of a component.

[0047] In particular, the first cleaning device is used to clean components that are laterally spaced from the local area.

[0048] The multi-axis robot used to carry the second cleaning device is preferably smaller than the multi-axis robot used to carry the first cleaning device.

[0049] Multi-axis robots and / or multi-axis robots preferably include multiple pivotable robotic arms, and are therefore particularly articulated arm robots.

[0050] The multi-axis robot is preferably arranged on a base, and the base of the multi-axis robot can be higher than the base of the multi-axis robot.

[0051] The cleaning station may include, for example, locks on the intake side and / or exhaust side, particularly sealing valves.

[0052] A conveying device can be used to transport components from a cleaning station to a painting chamber downstream of the cleaning station, wherein the painting chamber may include locks on the inlet side and / or outlet side.

[0053] A multi-axis robot with a second cleaning device and an automated moving machine with a first cleaning device are preferably arranged in the same cleaning station.

[0054] Multi-axis robots can carry only a single second cleaning device and / or automated motion machines can carry only a single first cleaning device.

[0055] The second cleaning device, consisting of cleaning felt and / or cleaning filaments such as plastic fibers, plastic bristles, or plastic blades, can conveniently clean parts, especially cleaning laterally along localized areas.

[0056] The names "first" and "second" cleaning devices are primarily used to distinguish the cleaning devices, not to determine their order of arrangement. Therefore, the second cleaning device and / or multi-axis robot can be arranged relative to the conveying / transporting direction of the parts, for example, before or after the first cleaning device and / or automated motion machine.

[0057] The present invention also includes a cleaning method for cleaning components (preferably vehicle body components), particularly using the cleaning equipment disclosed herein, and therefore the disclosure of the cleaning equipment can also be conveniently applied to the cleaning method.

[0058] This cleaning method is particularly suitable for cleaning parts laterally along wet, localized areas of the parts (especially when stationary).

[0059] The cleaning method mainly includes the following steps:

[0060] - The components are transported to the cleaning station via a conveyor system;

[0061] - The components are cleaned, preferably a large-area cleaning, using a first cleaning device; and

[0062] - A second cleaning device is guided laterally along a local area of ​​the component by a multi-axis robot to clean the component, preferably for sharp edges, and especially for small areas (narrow widths), so as to clean the component laterally next to the local area.

[0063] The order of the method steps in the claims may, but is not necessarily, fixed.

[0064] Therefore, for example, you can first perform large-area cleaning (area cleaning), and then perform sharp-edge cleaning, especially small-area cleaning (fine cleaning), or vice versa. Large-area cleaning and sharp-edge cleaning, especially small-area cleaning, can also be performed simultaneously, for example, at least multiple times at the same time.

[0065] The cleaning speed of the second cleaning device may be higher than that of the first cleaning device (e.g., at least 1.5 times, at least 2.0 times, at least 2.5 times, or at least 3.0 times).

[0066] For example, when cleaning a component using a second cleaning device, it can be done at least simultaneously with cleaning using a first cleaning device.

[0067] Alternatively or additionally, the cleaning of the component by the second cleaning device may take place at least before and / or after the cleaning by the first cleaning device.

[0068] The parts can also be sprayed to obtain a wet area some time before the cleaning method, and / or the parts can be sprayed some time after the cleaning method. Attached Figure Description

[0076] Figure 7 A top view schematic diagram of a cleaning device according to another embodiment of the present invention is shown. Detailed Implementation

[0077] The preferred embodiments of the present invention described with reference to the accompanying drawings are partially the same, wherein similar or identical parts are indicated by the same reference numerals. In order to avoid repetition, reference may also be made to the description of other embodiments.

[0078] Figures 1 to 3 Different views of a cleaning device 100 for cleaning component C, particularly a vehicle body component, are shown. The cleaning device 100 is specifically designed for cleaning component C laterally along still wet localized areas S of component C (see [reference]). Figure 4 ).

[0079] Cleaning equipment 100 includes a cleaning station 1 and a conveying device 2, the conveying device 2 being specifically designed for linearly transporting component C through the cleaning station 1, wherein... Figure 1 The dashed arrows in the diagram indicate the direction of transport / transportation of component C through cleaning station 1. Cleaning station 1 may include, for example, locks on the inlet and / or outlet sides.

[0080] In the direction of the arrow preceding cleaning station 1, component C may be configured with a wet localized area S (see...). Figure 4 The wet localized area S may include seams, particularly sealed seams, such as PVC seams. Following the cleaning station 1 in the direction of the arrow, a paint dipping station and / or one or more paint booths may be arranged to paint the component C after cleaning. However, the wet localized area S is not limited to seams and may also include general sprayed surfaces such as coatings, sealants, insulation, or anti-corrosion coatings, which may be sprayed onto the component C in the direction of the arrow before cleaning station 1.

[0081] The cleaning device 100 includes an automated motion machine 11, preferably a multi-axis robot (e.g., having at least 5 or 6 axes of motion), located on one side of the conveying device 2. This automated motion machine 11 carries a first cleaning device 10 for cleaning a large area of ​​component C. However, the first cleaning device 10 is preferably an emu feather roller. A similar device can also be conveniently arranged on the other side of device 2. However, the automated motion machine 11 can also be configured as a top or side-mounted device (see [link to documentation]). Figure 7 ).

[0082] In addition to the automated motion machine 11, the cleaning equipment 100 also includes a multi-axis robot 21 (e.g., having at least 5 or 6 axes of motion), which carries a second cleaning device 20 for cleaning sharp edges and small areas of component C. The same device can also be conveniently arranged on the other side of the conveyor 2.

[0083] The first cleaning device 10 is used to clean a large area of ​​component C, such as cleaning the top and / or one or more sides of component C.

[0084] The second cleaning device 20 is used to perform lateral cleaning of the component C along a predetermined local area S, targeting sharp edges, small areas, and especially precise areas.

[0085] like Figure 1 As shown, the multi-axis robot 21 and / or the second cleaning device 20 may be arranged in front of the automated motion machine 11 and / or the first cleaning device 10 relative to the conveying direction of component C. However, in the context of the present invention, the multi-axis robot 21 and / or the second cleaning device 20 may also be arranged after the automated motion machine 11 and / or the first cleaning device 10 relative to the conveying direction of component C.

[0086] The multi-axis robot 21 with the second cleaning device 20 and the automated moving machine 11 with the first cleaning device 10 can be conveniently arranged in the same cleaning station 1. However, the multi-axis robot 21 with the second cleaning device 20 and the first cleaning device 10 with the automated moving machine 11 can also be installed in different cleaning stations.

[0087] Especially from the illustration Figure 4 As can be seen from this, the multi-axis robot 21 can move along... Figure 4 The dashed arrow in the middle guides the second cleaning device 20 laterally, causing it to clean the component C, particularly the still-wet local area S, so that the component C can be cleaned laterally beside the local area S. The second cleaning device 20 is preferably (particularly a relatively small) plastic roller.

[0088] The local area S can be a joint where the surface is not yet fully dry (e.g., a sealed joint, especially a PVC joint) and / or a sprayed surface that is not yet fully dry (e.g., a paint, insulation, sealant, or anti-corrosion surface).

[0089] The primary objective is to keep the lateral distance x between the second cleaning device 20 and the still wet local area S as small as possible, but to prevent the second cleaning device 20 from entering the local area S. If the second cleaning device 20 enters the still wet local area S, the second cleaning device 20 and component C will become dirty, and the local area S itself will also be damaged.

[0090] Therefore, robot 21 is particularly suitable for guiding the second cleaning device 20 laterally along the local area S, that is, the second cleaning device 20 does not enter the still wet local area S, but the component C is still cleaned as much as possible toward the local area S. For example, the lateral distance x between the second cleaning device 20 and the local area S is less than 0.5 cm, or even the lateral distance x is basically 0 cm.

[0091] In this way, even though the local area S is not completely dry and is still wet, component C can still be cleaned laterally along the local area S. Therefore, it is not necessary to wait for the local area S to dry completely before cleaning component C.

[0092] The second cleaning device 20 may optionally be provided with at least one lateral shielding device 22 (e.g., Figure 4 The sidewalls or limiting discs shown schematically are designed to substantially prevent cleaning fibers from the second cleaning device 20, such as plastic fibers, plastic bristles, or plastic sheets, from deflecting (e.g., deforming) into the localized area S, particularly during sharp-edge cleaning, if the cleaning fibers are laterally deflected by the component C during the cleaning process. The second cleaning device 20 may include a single-sided or double-sided shielding device 22. The shielding device 22 may be composed of a resilient, non-deformable material or a material with very small elastic deformation.

[0093] Understandably, the first cleaning device 10 is also guided along the component C in a manner that does not enter the local area S. However, the first cleaning device 10 is suitably formed for cleaning large areas and is therefore particularly unsuitable for cleaning sharp edges. Thus, the first cleaning device 10 is preferably only used to clean areas on the component that are sufficiently far from the local area S.

[0094] The cleaning device 100 may include a control device 30 (e.g., a control computing device, computer, etc.), shown only schematically, which may store control programs for controlling the multi-axis robot 21 and / or the second cleaning device 20. The control device 30 can control the multi-axis robot 21 on one side of the conveyor 2 and / or the multi-axis robot 21 on the other side of the conveyor 2 to laterally guide the second cleaning device 20 along the local area S as previously described. However, the two multi-axis robots 21 may also be controlled by different control devices. The same applies to the second cleaning device 20.

[0095] In the described embodiment, the first cleaning device 10 is preferably a cleaning roller with a first outer diameter d1, and the second cleaning device 20 is preferably a cleaning roller with a second outer diameter d2, particularly a plastic cleaning roller, wherein the first outer diameter d1 is larger than the second outer diameter d2. Figure 5 As shown.

[0096] The outer diameter d1 of the first roller can be larger than the outer diameter d2 of the second roller, for example, at least 1.5 times or 2.0 times it.

[0097] Figure 6 A cleaning method according to an embodiment of the present invention is shown, wherein the cleaning method can be performed by the cleaning apparatus 100 disclosed herein.

[0098] In step S0, component C can be applied to obtain a wet local area S, i.e., applied before the cleaning method is performed.

[0099] In step S1, component C can be transported through cleaning station 1 via conveying device 2.

[0100] In step S2, the first cleaning device 10 performs large-area cleaning on component C.

[0101] In step S3, the sharp edges of component C can be cleaned, especially small areas, by the second cleaning device 20. The second cleaning device is guided laterally along the still wet local area S of component C by the multi-axis manipulator 21 so as to clean component C laterally next to the still wet local area S.

[0102] In step S4, component C can be sprayed, for example, painted, after the cleaning method.

[0103] Steps S1, S2, and / or S3 may be performed at least simultaneously and / or at least consecutively. Step S3 may be performed at least temporally before step S2, and vice versa.

[0104] When cleaning is performed using the second cleaning device 20, its cleaning speed is preferably higher than that when cleaning is performed using the first cleaning device 10 (for example, at least 1.5 times, 2.0 times, or 2.5 times higher).

[0105] The order of method steps in a claim may define the order of method steps, but it does not necessarily define the order of method steps.

[0106] Figure 7 A cleaning device 100 according to another embodiment of the present invention is shown.

[0107] Its characteristic is that the cleaning equipment 100 specifically includes a top machine RM with a first cleaning device 10 for cleaning large areas of component C, and preferably also includes side machines SM with the first cleaning device 10 on both sides of the conveying device 2. The cleaning devices 10 of the top machine RM and the side machines SM may be the same or different, but in any case, they are particularly suitable for cleaning large areas of component C.

[0108] This invention is not limited to the preferred embodiments described above. Instead, numerous variations and modifications are possible, which also utilize the inventive concept and are therefore within the scope of protection of this invention. Furthermore, this invention claims protection for the subject matter and features in the dependent claims, without relying on the referenced features and claims.
