Definitions
- TITLE Automaton for applying a patch to a heated surface
- the present invention relates to the manufacture of composite parts and, in particular, the deposition of patches of pre-impregnated or non-fibrous fibrous material on a part during manufacture.
- the present invention relates more particularly to grippers used to grip and drape patches of material on a part being manufactured, a patch having the form of a thin material whose tackiness must be activated by heat so that the patch adheres well to the target part.
- Placing a patch on large surfaces is generally carried out using a gripper to pick up and then place a patch at the desired location on the surface of the target part.
- Current solutions for example, use pneumatic, electrostatic or even mechanical grippers.
- the gripper grips the patch by suction by creating a depression which allows the patch to be pressed against the gripper until the gripper is positioned facing the part on which the patch must be positioned .
- the patch is then flattened and lightly compacted against the part, the depression is stopped and the gripper withdraws, leaving the patch on the target surface to be draped.
- the patch is for example an adhesive.
- FIGS. 1a and 1b show an automaton 1 for applying a patch according to the state of the art.
- the automaton 1 comprises a carrier 2 carrying a gripper 3 capable of gripping and the application of patches on a target surface 4.
- the carrier 2 is for example a robotic arm or a numerically controlled machine.
- a remote heating system 5 is present in the environment of the target surface 4 so that the wearer 2 of the automaton 1 enters a patch on a provision device (not shown) by means of the gripper 3, then approaches the patch near the heating system 5 as shown in Figure la.
- the patch thus heated has a stickiness making it stick to the target surface 4 when the patch is positioned by the gripper 3 on the target surface 4 (FIG. 1b).
- the provision device is for example a table, a treadmill or a drawer system.
- a computer 6 supervises the gripping, heating and laying operations.
- the heating of the patch when it is in contact with the gripper activates the tackiness of the patch also on its surface in contact with the gripper, which is detrimental to the proper detachment of the patch and the gripper when placing it on the surface. target.
- the draping time of the target surface is also increased by the heating and the additional path of the wearer between the heating system and the part to be draped.
- the object of the present invention is therefore to overcome the aforementioned drawbacks and to improve the efficiency of the systems for gripping and depositing patches, while limiting the sticking of the patch to the gripper, and improving the adhesion from the patch to the target surface to be draped.
- the subject of the present invention is an automaton for applying a patch to a surface to be draped, the automaton comprising a gripper capable of grasping the patch and depositing it on the surface to be draped, and a system for heating the surface to be draped capable of directly heating said surface to be draped.
- the direct heating of the target surface to be draped makes it possible to reduce the journey time of the gripper, and consequently, to avoid overheating of the patches, in order to avoid degrading the patch, and to promote the bonding of the patch to the surface to be draped, avoiding the sticking of the patch to the gripper.
- the gripper comprises a selectively activatable gripping system and a deformable material positioned against a gripping surface of the gripping system.
- the gripping system is pneumatic or mechanical or electrostatic.
- the automaton comprises a wearer and a head carried by the wearer, the head comprising a gripper and a system for heating the surface to be draped.
- the carrier is for example a robotic arm or a numerically controlled machine.
- the automaton comprises a first carrier comprising a first head and a second carrier carrying a second head, the first and second heads comprising one of the gripper and the other the heating system.
- the heating system is connected to the head of the automaton by a mechanism or a connection so that the heating system is retractable.
- the mechanism is a pivot link.
- the heating system is a lamp, or a hot air blower, or a resistor.
- the invention also relates to a method for positioning a patch on a surface to be draped, comprising the following steps:
- FIG 2b are schematic views of an automaton for applying a patch according to a first embodiment of the invention
- FIG 3 schematically illustrates a gripper of an automaton according to a first embodiment of the invention
- FIG 4b are schematic views of an automaton for applying a patch according to a second embodiment of the invention.
- FIG 5 schematically illustrates a head of an automaton according to a first variant of a second embodiment of the invention
- FIG 6 schematically illustrates a head of an automaton according to a second variant of a second embodiment of the invention.
- FIG 7 illustrates the steps of a method for gripping and positioning a patch using an automaton according to the invention.
- the automaton 7 comprises a first robotic carrier 9 comprising a first head 10, as well as a second robotic carrier 11 carrying a second head 12.
- the first head 10 comprises a gripper 13 suitable for gripping the patch 8 on a provision device 14 and depositing said patch 8 on a surface to be draped 15.
- the provision device is for example a work table, a treadmill or drawer system.
- the second head 12 comprises a system 16 for heating the surface to be draped 15 capable of directly heating said surface 15. Direct heating means heating of the part by the heating means of the heating system, without the part being heated by an intermediate piece.
- a computer 17 directs the automaton 7 and synchronizes the two carriers 9 and 11 so that the second carrier 11 carrying the second head 12 comes to heat the surface to be draped 15 by means of the heating system 16 during that the first wearer 9, by means of the gripper 13, grabs the patch 8 on the provision device 14, as illustrated in FIG. 2a.
- the first wearer 9 moves towards the surface to be draped 15 and comes to deposit the patch 8 on the surface to be draped 15 as soon as the second wearer 11 withdraws after having heated the surface to be draped 15.
- the gripper 13 as represented in FIG. 3, comprises a gripping system 18 that can be selectively activated, for example a pneumatic gripping system capable of creating suction by depression, and a deformable material 19 positioned at the level of the gripping surface of the gripping system.
- a gripping system 18 that can be selectively activated
- a deformable material 19 positioned at the level of the gripping surface of the gripping system.
- selectively activatable is meant the capacity of the gripping system to be able to grab a patch if the gripping system 18 receives this order by command from the computer 17, or not to grab it if the command from the computer so orders.
- the deformable material 19, for example an elastically deformable foam allows the gripper to adapt to any shape of the surface to be draped 15.
- electrostatic or mechanical gripping systems can also be used.
- the heating system 16 is for example a lamp, or a hot air blower or even a resistor.
- the gripper 13 and the heating system 16 are respectively connected to the first and to the second head 10 and 12 by links 20 allowing the gripper 13 and the heating system 16 to be retractable, and /or adjustable.
- the links 20 are for example pivot links or multi-axis systems.
- the automaton 21 comprises a robotic carrier 22 and a head 23 carried by said carrier 22.
- the head 23 comprises both a gripper 24 suitable for gripping the patch 8 and place it on the surface to be draped 15, and a system 25 for heating the surface to be draped 15 capable of directly heating the surface to be draped 15.
- This embodiment is, for example, preferable if savings in resources and space are necessary .
- a computer 26 directs the automaton 21 and, after the gripper 24 has grasped the patch 8, directs the head 23 towards the surface to be draped 15, and orients in a first step the head 23 so that the heating system 25 is arranged facing the surface to be draped 15 and heats the latter.
- the head 23 pivots in order to present the gripper 24 provided with the patch 8 facing the surface to be draped 15.
- the application of the patch takes place only a few moments after the heating of the surface to be draped.
- the surface being hot it thermally activates the patch to reinforce its tacky character on the side of the surface to be draped. This avoids overheating of the patch and facilitates bonding between the patch and the surface to be draped, without activating the stickiness of the patch on the gripper side.
- the head 23 includes the gripper 24 and the heating system 25.
- the gripper 24 comprises a gripping system 27 that can be selectively activated, for example a pneumatic gripping system capable of creating vacuum suction, and an elastically deformable material 28 positioned against a gripping surface of the gripping system 27.
- a gripping system 27 that can be selectively activated, for example a pneumatic gripping system capable of creating vacuum suction, and an elastically deformable material 28 positioned against a gripping surface of the gripping system 27.
- the deformable material 28, for example a foam, allows the gripper 24 to adapt to any shape of the surface to be draped 15.
- electrostatic or mechanical gripping systems can also be used.
- the heating system 25 is for example a lamp, or a hot air blower or even a resistor. It is activated and controlled by the computer 26 and the automaton 21, for example in terms of power and heating time.
- the heating system 25 is connected to the head 23 of the automaton by a mechanism 29, for example a pivot connection, allowing the heating system 25 to be retractable and thus to have a reduced size, for example when applying the patch 8.
- the mechanism 29 directly connects the heating system 25 and the gripper 24.
- the heating system 25 and the gripper 24 are connected directly to the head 23 of the automaton 21 so that their faces intended to enter into interaction with the surface to be draped 15 are opposite and always form the same angle, for example around 90°.
- This variant requires more movements on the part of the wearer 22.
- the head 23 is also provided with a connection 20 allowing the gripper 24 and the heating system 25 to be retractable, and/or adjustable.
- the link 20 is for example a pivot link or a multi-axis system.
- the method for positioning a patch 8 on a surface to be draped 15, the steps of which are represented in FIG. 7, comprises a first step 31 of gripping a patch 8 by the gripper 13 or 24 of PLC 7 or 21.
- a second step 32 of heating the surface to be draped 15 by means of the heating system 16 or 25 is then carried out.
- a last step 33 of laying the patch 8 on the surface to be draped 15 is carried out by means of the gripper.
