- Figures 1 and 2 show a machine (1) according to the invention, designed for the treatment of parts (2) of different shapes.
- the expression “of different shapes” includes parts of different geometries and/or dimensions. This expression is not limited to parts having the same geometry but different dimensions, for example flat films of different widths.
- the machine (1) is suitable for processing both flat-shaped parts, that is to say with a very small thickness (less than 5%) compared to the other dimensions, and volume parts, that is that is to say with three dimensions of the same order of magnitude or having a close order of magnitude.
- the parts can be of revolution (for example cylinders), or even parallelepipeds.
- the parts can be of irregular shape, that is to say solids composed of surfaces that are not necessarily orthogonal to each other, or have sides of unequal dimensions.
- the machine (1) according to the invention is designed to carry out surface treatments on the parts (2).
- Surface treatments are part of the applicant's area of expertise, and may include, but are not limited to, the following treatments: chemical deposition of a thin film, activation, pickling or cleaning, texturing (i.e. making patterns in relief on the surface of the part, these patterns having dimensions of the order of a nanometer up to a tenth of a meter), heat treatment (i.e. the modification of the crystalline structure of a metal via a predetermined temperature cycle).
- These treatments are called surface treatments, or superficial treatments, insofar as the area of effect of these treatments is limited at most to a few tenths of a millimeter below the surface of the part, and they are not intended to treat a part to the heart, that is to say in the depth of the part so that the entirety of the material has undergone the treatment.
- the machine (1) comprises an enclosure (10), a vacuum system (20), a plasma generator system (30), a vacuum deposition system (40), a transport system (50), a laser system (60) and a protection system (70).
- the machine (1) may comprise a plasma generator system (30) but no vacuum deposition system (40), or else comprise a vacuum deposition system (40) but no plasma generator system ( 30).
- such a machine (1) also comprises a heating system for degassing the parts (2) and the inside of the enclosure (10) before any other treatment.
- the machine (1) also comprises a system for injecting pure gases or mixtures of gases in order to introduce into the enclosure (10) in a controlled manner the gases necessary for the treatments.
- the heating system nor the gas injection system are shown in the figures.
- the systems (10-70) can be used separately or simultaneously with one or more of the other systems (10-70).
- the operator can choose to use the laser system (60) while the enclosure (10) is under vacuum, using the vacuum system (20).
- the operator can choose to carry out a treatment with the plasma system (30) on a first part (2) simultaneously with a treatment with the laser system (60) on a second part (2).
- the operator can choose to do a treatment with the laser system (60), then move the parts to the plasma treatment system (30).
- the operator can choose to make a first deposit using the vacuum deposition system (40), then a laser treatment with the laser system (60), then a second deposit with the vacuum deposition system empty (40).
- the enclosure (10) has a parallelepipedal shape, with two parallel horizontal walls constituting the top and the bottom of the enclosure (10), as well as four vertical walls two by two parallel constituting the sides of the enclosure (10).
- the walls can be of different shapes without departing from the scope of the invention.
- a cylindrical enclosure (10) comprising a single cylindrical vertical wall.
- This enclosure (10) may comprise a single compartment (11), as shown in Figures 1 and 2, or several compartments (11) as shown in Figure 5.
- the vacuum system (20) is intended to evacuate the atmosphere present in the enclosure (10).
- the system (20) can produce an air vacuum, that is to say an extraction of the air present in the enclosure (10) so that there prevails a pressure which can range, for example, from 10 2 Pa up to 10 9 Pa.
- the plasma treatment system (30) can be used to pickle the parts (2) in order to clean them for another subsequent treatment. Also, the system (30) can be used to activate a surface so that it can react to another subsequent treatment, such as a corona treatment for plastics or ceramics. In combination with the gas injection system, the plasma treatment system (30) can be used to perform PACVD type deposits (“plasma assisted Chemical vapor deposition”, “Plasma-assisted chemical vapor deposition” in French) .
- PACVD type deposits (“plasma assisted Chemical vapor deposition”, “Plasma-assisted chemical vapor deposition” in French) .
- the vacuum deposition system (40) is intended to carry out a deposition on the surface of the parts (2).
- the system (40) can be designed for PACVD or PVD (“physical vapor deposition” in English, “Physical vapor deposition” in French).
- the vacuum deposition system (40) can optionally be used to pickle the parts (2) if it supplies enough ionized species, as is the case for example for an arc deposition source.
- the transport system (50) is designed to receive the parts (2) and move them in the enclosure (10).
- This transport system (50) can be constructed in different ways.
- the system (50) comprises a plate (51) rotating around a central vertical axis, and turrets (52) rotatably mounted on the plate (51) around parallel vertical axes to the central axis, forming a carousel supporting one or more coins (2).
- the turrets (52) make it possible to exploit the greatest possible height of the enclosure (10), in particular for processing small parts (2).
- the plate (51) and the turrets (52) can rotate in the same direction or in the opposite direction.
- the turrets (52) can be motorized independently, thus making it possible to rotate the plate (51) and the turrets (52) separately or simultaneously.
- the turrets (52) can be fixedly mounted on the platter (51).
- the plate (51) can be devoid of turrets (52).
- the machine (1) is also equipped with the laser system (60), comprising a laser source (61) emitting a laser beam (62).
- the laser source (61) can be pulsed and emit pulses whose durations are of the order of a femtosecond, the picosecond or nanosecond.
- the laser source (61) can be multi-spectral (choice of the wavelength depending on the material).
- the laser system (60) can include several laser sources (61) in order to be able to treat several parts (2) at the same time, or several areas of a large part (2).
- the laser sources (61) can be identical (same wavelength, same pulse duration, same polarization, same beam shape) or different (wavelengths and/or pulse durations and/or polarization and/ or different beam shapes). Thereafter, reference will only be made to "the" laser source (61), even if there may be several.
- the laser system (60) includes a window (63), which is optically transparent to the beam (62), and which marks the transition between the laser system (60) and the enclosure (10).
- the system (60) comprises various optical devices, in particular a focusing and correcting device (65) for the beam (62), making it possible to concentrate the energy of the beam (62) at a chosen distance from said device (65). It is necessary to modify the focusing when the parts (2) to be treated are of different dimensions, and when the distance between the surface of a part (2) and the laser system (60) is not the same from one part (2) to another.
- the system (60) also comprises a deflection device (66) intended to orient the laser beam (62) and to scan the surface of the part (2) to be treated.
- the laser system (60) can be used in different ways and for different purposes:
- the cavities can be arranged in a discrete pattern, i.e. the cavities are disjoint from each other.
- the cavities can be arranged in a continuous pattern, i.e. the cavities are connected to each other.
- the cavities can comprise a mixture of discrete and continuous patterns.
- the pulses of the laser beam (62) generate a redistribution of the material and nanometric patterns are formed on the surface of the part.
- the nanopatterns can be hollow, bumpy or even both. This can be used to increase the specific surface of the part (2) for example.
- the machine (1) may also include a guard system (70) to protect the window (63) from the laser system.
- a guard system (70) to protect the window (63) from the laser system.
- the window (63) of the laser system (60) must remain as transparent as possible in order to guarantee the effectiveness of the laser treatment. This loss of transparency may come from deposits on the window (63), from the material ablated during the laser texturing of the parts (2), or else from the vacuum deposition system (40), or even from the plasma generator system ( 30).
- the protection of the window (63) can therefore be a major advantage for the machine (1), not only for the performance of the laser treatments to be carried out, but also in terms of the availability rate of the machine (1), if the operations maintenance to clean or replace the window (63) are less frequent.
- the machine (1) allows the implementation of different processes, comprising: a) a step of placing the enclosure (10) under vacuum, then a combination of the following steps: b) a step of laser treatment of the parts (2), and c) a step of plasma treatment of the parts (2), and/or d) a step of performing a vacuum deposition on the parts (2).
- the different steps a) to d) can be carried out in the same machine (1), suitable for processing parts (2) of different shapes, with great versatility.
- Steps a) and b) are always present in the process, with the addition of either step c), or step d), or the two steps c) and d).
- the order of steps b), c) or d) is not chronological.
- Step a) is prior to the other steps b), c) or d).
- Steps b), c) and d) can be carried out selectively to process the part(s), either separately from the other steps, or simultaneously with one or more of the other steps.
- Steps b), c), d) or their combinations can be carried out according to a configurable sequence of use, with an order of uses and/or a number of uses variables. For example, step b) can be carried out several times before carrying out step c) and/or d).
- FIG. 3 to 17 Other embodiments of a machine (1) according to the invention are shown in Figures 3 to 17. Certain constituent elements of the machine (1) are comparable to those of the first embodiment described above and, in for the purpose of simplification, bear the same reference numerals.
- Figure 3 shows a transport system (50) comprising only a turntable (51), without turrets (52).
- the plate (51) forms a carousel on which are arranged one or more coins (2). This configuration is advantageous for treating parts (2) of large dimensions.
- FIG. 4 shows a laser system (60) equipped with a single source (61) and a device for distributing and/or directing (67) the laser beam (62), so as to simultaneously treat several small parts (2), or several areas of the same large room (2).
- This distribution and/or orientation device (67) can be based on a division of the beam (62), for example by using semi-reflecting mirrors as illustrated in FIG. 4, or even on a deflection of the beam (62 ), for example by using prisms rotated so that the facets of the prisms direct the beam (62) successively towards one zone (or part) then towards another.
- the distribution device (67) without specifying whether it is a device for splitting or deflecting the beam (62).
- the laser system (60) can advantageously be arranged laterally. Unlike the machines (1) whose laser system (60) is arranged above, this configuration makes it possible to process so-called “volume” parts (2), as opposed to parts which are simply flat, such as discs or movies for example.
- FIG. 4 also shows turrets (52) equipped with plates (53) themselves mobile in rotation, so that three rotations could be controlled simultaneously or separately according to requirements: plate (51), turrets (52) and/or or turntables (53).
- FIG. 5 shows another machine construction (1), comprising a longitudinal transport system (50) and several compartments (11).
- the longitudinal transport system (50) comprises a carriage (54) supporting the parts (2) and rollers (55) supporting the carriage (54).
- the longitudinal transport system (50) can comprise a conveyor belt, a roller conveyor (55) without a carriage, a carriage (54) associated with an endless screw, or any other suitable device.
- the compartments (11) of the enclosure (10) are separated by vertical interior walls provided with valves (12), making it possible to partition or communicate the neighboring compartments (11). This construction is advantageous for protecting one of the systems (20-60) from pollution generated by the use of one of the other systems.
- the plasma system (30) is mounted on the upper wall of a first compartment (11), the vacuum deposition system (40) is mounted on the upper wall of a second compartment (22), and the laser system ( 60) is mounted on the upper wall of a third compartment (11).
- Other configurations can be envisaged without departing from the scope of the invention.
- Such a machine (1) generally comprises several vacuum systems (20), because during a treatment, a compartment (11) can be isolated from the other compartments (11). It is then necessary that this compartment (11) has its system (20) of pumping. The same is true for heating and gas injection systems.
- Figures 6 to 16 show different variants of protection systems (70) of the laser system (60).
- the solutions designed to be integrated into the protection system (70) are numerous, and can be used in combination in order to take advantage of the advantages of each and increase the effectiveness of the resulting overall protection.
- the system (70) comprises a cover (71) movable in front of the window (63), between an "open” position where the cover (71) is spaced from the window (63), when the system laser (60) is in use, and a "closed” position where the cover (71) is positioned in front of the window (63), when the laser system (60) is not in use while another system is used.
- This cover (71) can be a plate in the shape of the window (63), moved in translation by a jack (72). Any other relevant technical solution can also be considered, such as a diaphragm, for example.
- the system (70) comprises a film (73) movable in front of the window (63) between two rollers (74).
- This film (73) must be optically transparent with respect to the beam (62) and bring the least amount of optical disturbance to said beam (62).
- This film (73) aims to collect the projections which may arrive from the other systems (20-50), or from the parts (2) to be treated if a texturing by ablation is in progress.
- the operator can choose to leave the film (73) in a fixed position and to scroll it only when he considers that the film (73) has received too many projections, or else to scroll it continuously in order to guarantee maximum transparency of the film (73) at all times.
- An automatic advance after a certain duration can also be envisaged.
- the protection system (70) comprises a chamber (75) provided with an opening (76) and arranged in front of the window (63). This is a geometric solution aimed at increasing the distance between the window (63) and the opening (76) for the entry of the beam (62) into the enclosure (10).
- the chamber (75) defines a solid angle characterized by the ratio between the length of the chamber (75) and the width of the opening (76). If this angle is too open, as shown in Figures 10 and 13, the projections from the treatments have no difficulty penetrating this chamber (75) and coming to deposit on the window (63). But if the angle is closed, as shown in Figures 12 and 15, the chamber (75) forms a tunnel that the projections are unable to ascend, thus avoiding their deposit on the window (63).
- the chamber (75) defines an opening angle of less than 45 degrees between the window (63) and the opening (76). More preferably, this opening angle is the lateral opening angle, as distinct from the vertical opening angle.
- the protection system (70) is made by providing an oblique angle between the beam (62) and the window (63), and an oblique angle of incidence between the laser beam (62) and the surface of the parts to be treated (2).
- the projections resulting from the texturing are emitted in a direction which is not that of the passage slot of the laser beam (62) through the window (63).
- the projections directed towards the window (63) are thus reduced, or even eliminated.
- an orthogonal angle of crossing of the window (63) by the laser beam (62) is maintained and combined with an oblique incidence on the surface of the part (2).
- This can for example be obtained by offsetting the laser beam (62) with respect to the center of the rotary plate (51) or by tilting the window (63) with respect to the wall of the enclosure (10).
- the protection system (70) may comprise walls arranged between the window (63) and the enclosure (10), so as to optically isolate the path of the laser beam (62) and thus protect the window ( 63) projections.
- FIGS. 17 and 18 illustrate the advantage of providing the laser system (60) with a trajectory, focusing or shape correction device.
- this device can be used during the treatment of parts (2) not having a surface orthogonal with respect to the beam (62).
- Figure 17 shows a beam (62), projected onto a surface of the part (2) which is not orthogonal with the direction of the beam (2).
- the beam (62) is shown parallel and of circular section.
- the spot (68) resulting from the projection of the beam (62) on the part (2) is not a circle but an ellipse. This is problematic, particularly if the purpose of the laser treatment is to achieve texturing comprising circular cavities.
- the correction device makes it possible to modify the shape of the laser beam (62) so as to, in this example, correct the deformation induced by the surface.
- the laser system (60) can include a shaping module before the correction device, in order to obtain, for example, determined non-circular structures.
- Figure 17 also shows that the location of the point of impact of the beam (62) on the part (2) has an impact on the distance to be traveled between the spot (68) and the laser source (61). If the beam (62) is shifted to the right of the part (2), then the distance to be covered is greater. In reality, the beam (62) is not strictly parallel but is convergent, so as to be focused on the surface of the part (2). If the path to be traveled by the beam (62) has a variable length, then focus is lost. It is therefore judicious to provide the system (60) with a focusing correction device.
- FIG. 19 shows a cylindrical part (2) of which a part has already been treated and of which a new zone (64) is ready to be treated. Since the machine (1) may be intended to treat a large surface of one or more parts (2), this surface should be scrolled past the system or systems (20-60) in use.
- the transport system (50) is therefore designed so as to move the part (2) so that two successive treatment zones (64) are contiguous. This point will be more particularly illustrated by taking laser processing as an example, although this characteristic of the transport system (50) can be implemented with the other systems (30, 40).
- Carrying out a laser treatment implies that the surface of the part (2) must be positioned facing the window (63) of the laser system (60).
- the laser system (60) includes complex optical devices, requiring significant mechanical adjustment and stability.
- the laser system housing (60) is fixedly positioned.
- the relative movement of the beam (62) with respect to the part (2) is achieved by moving the optical devices of the laser system (60) and/or by moving the part (2) to be treated. It follows that the treatment of the parts (2) is generally done by successive zones (64), possibly with several zones (64) treated in parallel by several laser beams (62).
- the laser system (60) processes the part of the part (2) which is apparent to it.
- the part (2) is moved so as to place a next zone to be treated facing the laser system (60).
- this displacement is carried out simultaneously with the processing in progress.
- this displacement can be carried out alternately with the treatment.
- This is illustrated in Figure 19, where it can be seen that part of a cylindrical part (2) has already been treated and that a new zone (64) is ready to be treated.
- the positioning accuracy of the part (2) can for example be increased by means of a position encoding device, comprising for example an encoder placed within the kinematic chain setting in motion the plate (51) or the or trolleys (54).
- visual markers capable of cooperating with one or more optical sensors can be provided. These visual cues can for example be marks made on the part (2) so as to be detected by a camera. It is also possible to envisage that the visual cues are the already treated areas themselves, if these areas have a different color or texture which can be detected by a sensor or by a camera, with for example the use of polarized light or having a chosen wavelength.
- the part (2) can be continuously movable with respect to the laser system (60), without this changing the interpretation of the provisions explained above.
- the zone (64) being processed then becomes a zone of smaller surface area, and updated much more frequently.
