Description
technical field
[0001] The present invention relates to a fixing module for the removable fixing of a micromechanical component, such as a watch component, in order to hold and process a plurality of components during their manufacture and / or finishing. The present invention also relates to a fixing support comprising a plurality of fixing modules. State of the art
[0002] The manufacture of watch components has been undergoing significant changes for many years due to the volatile economic climate, the evolving trends and codes of the luxury market, and the overall modernization of the luxury industry. This shift has led from traditional craftsmanship to an organized, industrialized, streamlined, and automated industry, enabling various stakeholders to maintain and improve their margins and profits while adapting to the market's demands for quality, price, and product availability. Luxury brands are also attentive to the evolution of their image and performance, ensuring that this industrial approach does not diminish the appeal of their products to traditional buyers and collectors. They are expanding their target audiences by introducing new features and technologies, and improving their distribution and representation across different markets and countries worldwide.
[0003] To illustrate this point, we can take the example of electroplating or the final washing of watch dial appliqués. These small, lightweight parts consist of a head, which is the visible part, and usually two feet, typically 0.25 mm in diameter, allowing them to be attached to the dial by riveting or welding. The two feet are also used to hold the appliqués in a conventional mounting bracket, often called a "slatted bracket," consisting of an outer conductive frame that guides several dozen conductive blades. These blades hold and clamp the parts to the surface of the bracket by means of two screws passing through the frame. The guidance of these blades also ensures the electrical contact between the appliqués and the outer conductive frame, which is essential for the plating process.These bike racks are rather heavy and expensive but reusable if the user takes care of them and maintains them regularly.
[0004] Preparing the wood for coloring is a meticulous and time-consuming process, as positioning the appliques between the slats of the glass requires a certain amount of dexterity. The feet of the appliques must be positioned between the slats, which are not held in place during handling, without any undue movement that could dislodge the slats or the appliques. Once the appliques are in place between the slats, they are tightened until sufficient torque is achieved. The correct torque is determined by the operator's judgment or with a torque wrench.The holding force exerted on each of the appliques is not necessarily uniform due to manufacturing uncertainties in both the frame and the appliques. The operator is often required to apply a higher tightening torque than necessary to prevent appliques from detaching from the frame during handling. In such cases, the feet can be crushed, rendering the affected appliques unusable for assembly on the dial. Furthermore, when the frame is reused, the clearance between the tines and the outer conductive frame can decrease with each successive use. For example, in a coloring process, the colored coating is deposited on all conductive surfaces. Thus, the friction of the tines as they move within the frame gradually increases, again necessitating an increase in tightening torque to ensure the appliques remain securely in place.
[0005] Another disadvantage of lamellae rollers is that they tend to carry chemicals between different processes, for example between the baths of electroplating, given the many gaps present in the configuration of a lamellae roller.
[0006] Document CH707420 describes a mounting bracket comprising a base with a plurality of clamping units for the removable attachment of a component. Each clamping unit includes a spring element arranged so that the movable element can move between a closed position, in which the component is held within the clamping unit, and an open position, in which the component is released from the clamping unit. A second spring element holds the fixed component in the closed position. However, the clamping unit does not provide uniform clamping on the component. Furthermore, if the components vary in size, proper clamping, and therefore secure attachment of the component within the clamping unit, is not guaranteed for all components mounted in the bracket. Brief summary of the invention
[0007] The present invention relates to a fastening module for the removable attachment of a component, comprising a fixed section and a movable section configured to move relative to the fixed section; a fixed jaw integral with the fixed section; a spring element of planar geometry comprising a folded spring blade, a fixed end integrally connected to the fixed section, and a free end integrally connected to a rigid blade comprising a movable jaw. The spring element is deformable in a first direction, between a compressed position in which the movable and fixed jaws form a gap for receiving the component, and an extended position in which the component received in the gap is held fixed between the movable and fixed jaws. The movable and fixed jaws have a length in a second direction substantially perpendicular to the first direction.A damping element is arranged between the moving jaw and the spring element. The damping element is configured so that the moving jaw exerts a substantially uniform clamping force along its length on the component received in the gap when the spring element is in the extended position. The damping element comprises at least one damper blade integral with the moving jaw and attached to the rigid blade by means of a flexible pivot. The damper element has a width that is at least 20% less than the width of both the moving jaw and the spring blade.
[0008] In this disclosure, the term "width" refers to a dimension that is measured along a first x direction and the term "length" refers to a dimension that is measured along a second y direction.
[0009] The present invention also refers to a mounting support comprising a plate having a plurality of mounting modules.
[0010] Also described is an actuator system configured to cooperate with the mounting support so as to move the moving section of the clamping modules and to actuate the spring element between the deployed and compressed positions.
[0011] The fastening module described here guarantees uniform clamping on components of various shapes, received within the gap when the spring element is in the deployed position. Uniform clamping is also achieved despite manufacturing variations in the fastening module.
[0012] The yield of components treated on the mounting support is higher than when using a conventional mounting support. Brief description of the figures

Example(s) of implementation method
[0014] There figure 1The figure shows a fastening module 10 for the removable fastening of a component (not shown), according to one embodiment. The fastening module 10 comprises a fixed section 23 and a movable section 22 configured to move relative to the fixed section 23. A fixed jaw 13 is integral with the fixed section 23. The fastening module 10 also comprises a spring element 11 having a fixed end 111 integral with the fixed section 23, and a free end 112 having a movable jaw 12. The spring element 11 has a planar geometry (flat spring).
[0015] The spring element 11 is deformable between a compressed position in which the movable jaw 12 and the fixed jaw 13 form a gap 17 for receiving the component, and an extended position in which the movable jaw 12 contacts the fixed jaw 13 when no component is present. When a component is received in the gap 17, it is held fixed between the movable jaw 12 and the fixed jaw 13 in the extended position of the spring element 11. The clamping force exerted by the spring element 11 on the movable jaw 12 against the fixed jaw 13 is exerted by the extension force of the spring element 11.
[0016] According to one embodiment, the spring element 11 extends (or deforms) between the compressed position and the deployed position substantially perpendicular to the movable jaw 12 and the fixed jaw 13 (along a first direction x in the figure 1). The movable jaw 12 and the fixed jaw 13 have a length L extending along a second direction y substantially perpendicular to the direction of deformation of the spring element 11, that is to say to the first direction x.
[0017] In one embodiment, a damping element 16 is arranged between the movable jaw 12 and the spring element 11. The damping element 16 is configured such that the movable jaw 12 exerts a substantially uniform clamping force along its entire length L on the component received in the gap 17, when the spring element is in the deployed position. The damping element 16 thus ensures uniform clamping on the component received in the gap 17 when the spring element 11 is in the deployed position.
[0018] Uniform clamping is determined by the shape of the spring element 11. In particular, the stroke and homogeneity of clamping as well as durability over time can be determined by its geometry.
[0019] For example, the spring element 11 may include a leaf spring 110 having a folded shape. For example, the spring element 11 may have a sinuous shape that undulates and folds back on itself several times. The leaf spring 110 advantageously has at least one fold 113, so that the spring element has a sufficiently long stroke between the compressed and extended positions. Such a spring element is very flexible and can be of considerable length. The clamping force of the spring element 11, as well as the stroke of the spacer 17, can be determined and adapted for each of the components intended to be fixed in the fixing module 10 by adjusting the length and width of the leaf spring 110 and the number of folds 113.
[0020] According to the configuration illustrated in the figure 1 The spring blade 110 has a serpentine shape comprising at least one bend (or fold) 113, each bend alternately changing the orientation of the spring blade 110. By the term "serpentine" it is understood that the spring blade 110 comprises at least one bend 113, and preferably several bends 113 alternately changing the orientation of the spring blade 110.
[0021] The spring blade 110 can take a different shape than the one shown in the figure 1 For example, the 110 spring blade can have a zig-zag shape. Alternatively, the 110 spring blade is coiled with at least two turns.
[0022] Uniform clamping is also ensured by the presence of the damping element 16. Uniform clamping guarantees sufficient retention of the components fixed to the fixing module 10, preventing the components from becoming detached from the fixing module 10 during the processes and handling of the fixing module 10. The damping element 16 also allows for uniform clamping despite manufacturing variations in the fixing module 10 as well as slight errors in the positioning of the component within the gap 17.
[0023] According to one embodiment, the shock-absorbing element 16 comprises at least one shock-absorbing blade 161 integral with the movable jaw 12 and connected to the elastic section 110 by an elastic pivot 162.
[0024] According to one embodiment, the shock absorber blade 161 can be arranged substantially parallel to the movable jaw 12.
[0025] The free end 112 of the spring element 11 is attached to a rigid blade 114. The elastic damper blade 161 is attached to the rigid blade 114 via the elastic pivot 162. The rigid blade 114 is substantially parallel to the damper blade 161. Preferably, the damper blade 161 and the elastic pivot 162 have a lower resistance to elastic deformation than the elastic resistance to elastic deformation of the rigid blade 114.
[0026] In general, uniform clamping along the entire length L on the component received in the gap 17 is achieved thanks to the free end 112 of the fixing module 10 which is "elastically mobile" relative to the fixed section 23. Uniform clamping can also be achieved by choosing the dimensions of the shock absorber element 16.
[0027] For example, the shock-absorbing blade 161 may have a thickness D 161 (measured along the first x direction, i.e. the width of the shock-absorbing blade 161) which is at least 20% less than the thickness (the width) of the movable jaw 12 (measured along the first x direction) and the width of the spring blade 110.
[0028] On the other hand, the length L 162 (measured along the second y direction) of the elastic pivot 162 is at least 50% smaller than the length L 161 (measured along the second y direction) of the shock-absorbing blade 161.
[0029] Furthermore, the width D 111 (measured along the second y direction) of the fixed end 111 and the width D 112 (measured along the second y direction) of the free end 112 are, respectively, at least 20% greater than the width of the spring blade 110.
[0030] Furthermore, the width I 22 (measured along the second y direction) of the movable section 22 is at least 25% greater than the length L of the movable and fixed jaws 12, 13.
[0031] It should also be noted that in order for the clamping force exerted by the spring element 11 on the movable jaw 12 against the fixed jaw 13 to remain uniform over time while allowing sufficient deformation of the spring element 11 in order to be able to insert the components into the gap 17, the stresses exerted on at least one of the parts: the fixed end 111, the free end 112, the elbows 113, the shock absorber blade 161, and / or the elastic pivot 162 should not exceed the elastic resistance of the material in which these parts are made.
[0032] The fixing module 10 can also include a stop element, for example a stop 14 arranged at each end of the movable jaw 12. The stop element 14 can serve as a reference for positioning the component in the gap 17 but also for reworking the parts in decoration and material addition / removal processes.
[0033] In one embodiment, the clamping module 10 is configured so that the spring element 11 is in the deployed position when actuated. In this case, the clamping force exerted by the spring element 11 on the movable jaw 12 against the fixed jaw 13 is exerted by the deployment force of the spring element 11.
[0034] Alternatively, the fastening module 10 is configured so that the spring element 11 is in the compressed position when actuated. In such a configuration, the fastening module 10 may advantageously include a locking element configured to hold the spring element 11 in the extended position when not actuated.
[0035] The fixing module 10 allows for the acceptance of components of different shapes. The configuration of the spring element 11 allows for a certain degree of dimensional variation from one component to another and for manufacturing variations in the fixing module 10, the variations being compensated for by the stroke of the spring element 11.
[0036] There figure 2represents two substantially parallel rows 29, each row 29 comprising a plurality of clamping modules 10. The clamping modules 10 in a row are kinematically connected in series, i.e. each of the clamping modules 10 is connected to an adjacent clamping module 10 in the row 29 via the spring element 11. The displacement from the deployed position to the compressed position of each of the rows of clamping modules 10 is obtained by a displacement of the moving section 22 relative to the fixed section 23. The width I 22 of the moving section 22 is shown in the figure.
[0037] In the example illustrated in the figure 2 , the two rows 29 of fixing modules 10 share the same movable section 22. In this configuration, the displacement of the movable section 22 relative to the fixed section 23 allows the spring elements 11 of the clamping modules 10 of the two rows 29 to be acted on simultaneously.
[0038] The spring elements 11 of each of the clamping modules 10 of the two rows can be actuated by pulling on one end of the movable section 22. For example, the movable section 22 may include at one end gripping means 27 allowing easier pulling on the movable section 22, or cooperating with a tool configured to pull on the movable section 22. In the example illustrated in the figure 2 The gripping means 27 includes an opening or eyelet. The movable section 22 is pulled in a direction substantially parallel to the deployment direction of the spring element 11 (indicated by the arrow in the figure 2). When the movable section 22 is pulled, the fixed section 23 can be held fixed relative to the movable section 22. To this end, the fixed section 23 can be held fixed by fixing the end opposite the pulled end of the movable section 23. The fixed end of the fixed section 23 may have fastening means 28, for example an opening made in the fixed section 23.
[0039] There figure 3 shows a mounting bracket 20 comprising a plate 21 having a plurality of mounting modules 10, according to one embodiment. In the example of the figure 3 The mounting bracket 20 comprises ten rows 29 arranged substantially parallel to each other, each row 29 comprising a plurality of mounting modules 10 kinematically connected in series. In the example of the figure 3, the fixing modules 10 included in two adjacent rows 29 share the same movable section 22, so that the displacement of the movable section 22 relative to the fixed section 23 allows the spring elements 11 of the clamping modules 10 of the two rows 29 to be acted simultaneously.
[0040] Alternatively, the plurality of fixing modules 10 can be configured so that the displacement of the movable section 22 actuates the spring elements 11 of the clamping modules 10 of each of the rows 29 independently of each other.
[0041] It goes without saying that the mounting bracket 20 can comprise a different number of rows 29 and that each row 29 can comprise a different number of clamping modules 10, as illustrated in the figure 3 The clamping modules 10 can also be arranged differently than the arrangement illustrated in the figure 3The presence of the damping element 16 on each of the clamping modules 10 also makes it possible to uniform the clamping force on all the components received in the spacing 17 of the different clamping modules 10.
[0042] The plate 21 can be made of various materials depending on the intended use. For example, the plate 21 can be made of metal such as stainless steel or any other metal, metal alloy, or any other material with the desired mechanical properties for the clamping module 10. For example, the material should allow sufficient flexibility for the spring element 11. In particular, the plate 21 can be made of sheet metal, such as highly work-hardened stainless steel. The plate 21 can have a thickness between 0.1 mm and 2 mm, with lateral dimensions that depend on the size of the components to be secured, the number of components, and the requirements of the process using them.
[0043] The material forming the mounting bracket 20 can be chosen according to its intended use. For example, electrical contact can be guaranteed on each component clamped within the gap 17 if the clamping module 10 is made of an electrically conductive material. The movable jaw 12 and the fixed jaw 13 can be made of a material with no elastically deformable zones. For example, the choice of stainless steel allows for the use of aggressive chemical and mechanical treatments to remove any material deposits made during the manufacturing processes of the components mounted on the mounting bracket 20.
[0044] The mounting bracket 20 can be manufactured by cutting the mounting modules 10 from the plate 21. The cutting of the plate 21 can be carried out by any suitable method, for example by a laser cutting method or by electro-erosion.
[0045] The mounting bracket 20 can be easily cleaned as it has no obstructions, gaps, or assembled parts that could trap impurities. The mounting bracket 20 also ensures very low contamination through entrainment between different processes and very low pollution through outgassing in all vacuum, high vacuum, and ultra-high vacuum processes.
[0046] There figure 4 shows a side view and the figure 5 shows a bottom view of the mounting bracket 20, according to one embodiment. In this configuration, the periphery 22 of the plate 21 includes a flap 26 folded on at least two sides (the figure 5The figure illustrates the mounting bracket 20 with a flap 26 on all four sides of the plate 21. The flaps 26 increase the rigidity of the mounting bracket 20, allow for the stacking of multiple mounting brackets 20, and also provide a gripping interface, either manually or via specific tooling for a particular process. The flaps 26 ensure the geometric stability of the plate 21 during decoration and material addition / removal processes. However, they are not always necessary and, for certain applications, can be omitted or replaced by mechanical elements assembled to the mounting bracket (20) to create feet or gripping interfaces.
[0047] The periphery 22 of the plate 21 may include at least one positioning hole 24 and a keying feature 25. The positioning hole(s) 24 allow the precise position of each of the components held by the fixing support 20 to be known in relation to each of the positioning holes 24 present on the periphery of the fixing support 20. In combination with the stops 14, the positioning hole(s) 24 allow the components to be reused in decoration and material addition / removal processes.
[0048] The flaps 26, in combination with the positioning hole(s) 24, and possibly oblong openings 241 also arranged at the periphery 22 of the plate 21, allow for quick gripping and positioning of the fixing support 20 in processes and handling.
[0049] The mounting support can be used for machining, chemical or electrochemical processing, cleaning and storage, decoration processes and adding / removing material from components attached to the support.
[0050] According to one embodiment, an actuator system is provided to cooperate with the mounting support 20 so as to move the movable section 22 of the clamping modules 10 in order to actuate the spring element 11.
[0051] An example of an actuator system 30 is illustrated in the figure 6 .The actuator system 30 comprises actuators 31, each actuator 31 being configured to cooperate with the gripping means 27 of the mounting bracket 20 when the mounting bracket 20 cooperates with the actuator system 30. Each of the actuators 31 may include an actuator driving a connecting element 32 that engages with the gripping means 27 so as to actuate the spring elements 11 of the clamping modules 10 by pulling on the gripping means 27. The connecting element 32 may include a rod or lug that engages with each of the eyelets 27 of the mounting bracket 20.
[0052] In one variant, the actuator system 30 comprises a single actuator 31 driving several connecting elements 32 so as to actuate several spring elements 11 simultaneously.
[0053] In the configuration where the spring element 11 is in the deployed position when actuated, each of the actuators 31 can be configured to pull on the moving section 22, for example by moving the connecting element 32 towards the periphery of the actuator system 30, as shown by the solid arrow in the figure 6 In the configuration where the spring element 11 is in the compressed position when actuated, each of the actuators 31 can be configured to push on the moving section 22, for example by moving the connecting element 32 towards the center of the actuator system 30, as shown by the empty arrow in the figure 6 The movement of the connecting element 32 can be guided along a guide slot 34.
[0054] The actuator system 30 may also include fastening elements 35, each fastening element 35 being configured to cooperate with the fastening means 28 of the mounting support 20 when the mounting support 20 cooperates with the actuator system 30. For example, the fastening elements 35 may include a rod or lug engaging with each of the openings 28 made in the fixed section 23 of the mounting support 20.
[0055] The actuator system 30 can be configured to actuate at least two rows 29 of clamping modules 10 simultaneously or to actuate each row 29 of clamping modules 10 independently.
[0056] The actuator system 30 may also include one or more positioning studs 35, each positioning stud being intended to cooperate with the positioning hole(s) 24 at the periphery 22 of the plate 21. The actuator system 30 may also include additional means intended to cooperate with the keying device 25 so as to ensure the correct positioning of the mounting support 20 on the actuator system 30, and be actuated manually, electrically or pneumatically.
[0057] There figure 7 The figure shows the fastening module 10 in an unclaimed embodiment. In this configuration, the shock-absorbing element 16 is not present and the free end 112 is directly and securely connected to the rigid blade 114. The movable jaw 12 is fixed to the rigid blade 114.
[0058] In this configuration, a substantially uniform clamping along the entire length L on the component received in the gap 17 can be achieved by the shape of the spring element 11 as mentioned above. Uniform clamping can further be achieved by selecting the dimensions of the fixed end 111 and the free end 112 relative to the width of the spring blade 110, as well as the dimensions of the moving section relative to the length L of the moving and fixed jaws 12, 13.
[0059] In particular, the width D 111 (along the second y direction) of the fixed end 111 and the width D 112 (along the second y direction) of the free end 112 are, respectively, at least 20% greater than the width of the spring blade 110. The width D 22 (along the second y direction) of the moving section 22 is at least 25% greater than the length L of the moving and fixed jaws 12, 13.
[0060] In the execution form of the figure 7The fixed jaw 13 may have a notch 130 configured to receive the component. In the illustrated example, the notch 130 is triangular, but other shapes of the notch 130 are possible. The presence of the notch 130 is advantageous when the component received in the space 17 is cylindrical, for example.
[0061] Note that in the presence of notch 130, the spacing 17 is always defined by the space between the movable jaw 12 and the fixed jaw 13 and will therefore vary according to the profile of the fixed jaw 13 including notch 130.
[0062] Generally, the gap 17 can be configured to be smaller than the largest dimension of the component when the spring element is in the deployed position. If the fixed jaw 13 has a notch 130, the maximum gap at the notch will be smaller than the largest dimension of the component. The gap 17 can also be configured so that, when the component is inserted into the gap 17, the deformation stroke of the spring element 11 is such that the spring element does not deform plastically. Of course, this will depend, among other things, on the geometry of the spring element 11 and the material from which it is made.
[0063] The spring blade 110 advantageously has at least one bend 113, so that the spring element has a sufficiently long stroke between the compressed and extended positions. Such a spring element is very flexible and can be of considerable length. The clamping force of the spring element 11, as well as the stroke of the gap 17, can be determined and adapted for each of the components intended to be fixed in the fixing module 10 by adjusting the length and width of the spring blade 110 and the number of bends 113.
[0064] There figure 8 illustrates a variant of the arrangement shown in the figure 2 . Here, the gripping means 27 are provided with a gripping stop 270 configured to come into contact with an indentation 230 made in the fixed section 23. In this way, the amplitude of displacement of the deployed position when pulling the movable section 22 can be limited.
[0065] There figure 9shows the mounting support 20 comprising a plate 21 having ten rows 29, each comprising twenty-five mounting modules 10. The mounting support 20 is well suited for a component having two feet intended to be inserted into the spacing 17.
[0066] There Figure 10 shows the mounting bracket 20 according to another variant, in which the plate 21 also includes two foot openings 36 for each mounting module 10. For example, the foot openings 36 can be configured to receive a third and fourth foot of a component, the other two feet of the component being inserted into the gap 17. Note that the plate 21 can include a single foot opening 36 or more than two foot openings 36 for each mounting module 10.
[0067] There figure 11shows the mounting bracket 20 according to another unclaimed variant, in which the mounting modules 10 correspond to the configuration of the figure 7 .
[0068] There figure 12 The figure shows the mounting bracket 20 according to another variant, in which each row 29 comprises the mounting modules 10 arranged in an arc. The mounting bracket 20 can comprise several rows 29 arranged along a circumference and concentrically. Reference numbers used in the figures
