Description

Title of the invention: Burn-in system and associated method of use

[0001] The present invention relates to a debugging system comprising:

[0002] - a support for receiving equipment to be tested; and

[0003] - an actuation device on which the receiving support is intended to be mounted, the actuation device is intended to generate mechanical stresses on the equipment to be tested received on the receiving support.

[0004] In such systems, for each of a plurality of equipment to be tested, a specific receiving support is provided for said equipment to be tested.

[0005] However, the receiving supports of the prior art are massive. For example, the mass of the receiving supports of the prior art ranges from 5 kg to 15 kg. The mass of some supports therefore exceeds the values ​​recommended by ergonomic standards such as standard NF X35-109. During the installation and removal of the receiving supports, failure to comply with these ergonomic standards can lead to accidents or at least cause discomfort for the operators.

[0006] Another disadvantage is the storage space required to store the various receiving media.

[0007] One aim of the invention is therefore to propose a debugging system that reduces the physical strain of handling for operators, reduces the bulk generated by the system and improves the repeatability of mechanical tests.

[0008] To this end, the invention relates to a debugging system of the aforementioned type, in which the receiving support comprises:

[0009] - a sole extending along a longitudinal direction and a direction transverse substantially perpendicular to the longitudinal direction, mounted on the actuation device;

[0010] - a base adapted to receive the equipment to be tested, the base being suitable for mounting removable from the sole.

[0011] Thanks to these features, during handling operations, only the base needs to be changed by the operators. As a result, the load to be lifted is considerably reduced. Furthermore, to carry out tests on different types of equipment, it is only necessary to provide a variety of bases adapted to the different types of equipment. The sole is common to all. The overall size of the system is thus reduced: the single sole remains mounted on the actuation device and only the bases (which are smaller than the entire receiving support) are stored.

[0012] According to other advantageous aspects of the invention, the debugging system comprises one or more of the following features, taken individually or in all technically possible combinations:

[0013] - the base includes a base defining a surface for receiving the equipment to test, the receiving surface extending in a horizontal plane substantially parallel to the longitudinal and transverse directions,

[0024] - for each through guide groove, a positioning mechanism said jaw, said positioning mechanism being integral with said jaw and intended to cooperate with the through guide groove to guide the translational movement along the transverse direction of said jaw and / or to maintain said jaw in position along the transverse direction;

[0025] - each positioning mechanism comprises:

[0026] - a screw integral with said jaw, said screw comprising a shank extending into the corresponding guide groove;

[0027] - an additional screwing member extending into the guide groove corresponding and intended to cooperate with the shank of the corresponding screw by screwing, the complementary screwing member having a cross-section taken along a plane substantially perpendicular to the transverse direction substantially complementary to a cross-section of the guide groove taken along the plane substantially perpendicular to the transverse direction;

[0028] - each guide groove has flared edges,

[0033] - the receiving support further comprises at least one fixed reinforcement mounted at remains on the sole and forms a stop against which the base is intended to rest in the longitudinal direction;

[0034] - when the base rests on the stop formed by the fixed reinforcement, the surface of reception of the equipment to be tested extends along one edge of the sole;

[0035] - the base and the stop element are made of material;

[0036] - the actuation device includes a receptacle on which the support of reception is intended to be mounted and at least one actuator configured to generate mechanical stresses on the receiving support received on the receptacle.

[0054] With reference to [Fig.1], a debugging system 10 according to the invention is described.

[0055] The burn-in system 10 includes an actuation device 12 and a support 20 for receiving equipment to be tested, intended to be mounted on the actuation device 12.

[0056] The actuation device 12 is intended to generate mechanical stresses on the equipment to be tested received on the receiving support 20, in particular by generating mechanical stresses on the receiving support 20.

[0057] The actuation device 12 is specifically intended to excite the equipment under test, received on the receiving support 20, into vibration. The actuation device 12 is, for example, a vibrating pot (also called an exciter or vibrator, or simply a "shaker" in English).

[0058] In particular, the actuation device 12 includes a receptacle 14 on which the receiving support 20 is intended to be received and at least one actuator 16 configured to generate the mechanical stresses on the receiving support 20 received on the receptacle 14.

[0059] Advantageously, the actuation device 12 further comprises a main body 13 receiving the receptacle 14 and at least one actuator 16.

[0060] Even more advantageously, the actuation device 12 includes other components classically implemented in prior art actuation devices 12, not illustrated in the figures and not described in more detail here for the sake of brevity.

[0061] The receptacle 14 is, for example, a tray. In one example, the receptacle 14 is removably mounted on the main body 13 of the actuation device 12. This allows, in particular, for maintenance operations to be carried out on the main body 13 and / or the receptacle 14. Alternatively, the receptacle 14 is permanently mounted on the main body 13 of the actuation device 12.

[0062] At least one actuator 16 is, for example, an electrodynamic vibrator.

[0063] With reference to figures 2 to 6, the receiving support 20 comprises a base 22 and a plinth 34A.

[0064] Advantageously, the receiving support 20 further comprises a vise 62.

[0065] Even more advantageously, the receiving support 20 further includes a device 74 for translating the jaws 64 of the vise 62.

[0066] Even more advantageously, the receiving support 20 also includes at least one fixed reinforcement 92.

[0067] Advantageously, the receiving support 20 further comprises at least one auxiliary base 34B. In what follows, only one auxiliary base 34B is described. Those skilled in the art will understand that the invention relates to a support 20 comprising as many auxiliary bases as necessary depending on the number of different auxiliary devices to be tested.

[0068] The sole 22 extends along a longitudinal direction X and a transverse direction Y substantially perpendicular to the longitudinal direction X.

[0069] A vertical direction Z substantially perpendicular to the longitudinal direction X and to the transverse direction Y is also defined.

[0070] The sole 22 is intended to be mounted on the actuation device 12.

[0071] In particular, the sole 22 has interfaces complementary to interfaces of the actuation device 12, in particular to interfaces of the receptacle 14, so that the actuation device 12, in particular at least one actuator 16, is capable of actuation of the sole 22, in particular of moving the sole 22, by actuation of the receptacle 14.

[0072] Advantageously, the sole 22 is intended to be received on the receptacle 14 of the actuation device 12.

[0073] Even more advantageously, the sole 22 has substantially the shape of a rectangular parallelepiped.

[0074] The sole 22 has:

[0075] - an upper surface 24A extending parallel to a horizontal plane PH substantially perpendicular to the vertical direction Z and intended to be oriented towards the base 34A or the auxiliary base 34B; and

[0076] - a lower surface 24B opposite the upper surface 24A and in particular intended to be in mechanical contact with the actuation device 12.

[0077] Advantageously, the upper surface 24A of the base 22 has a central portion 25 intended to be opposite the base 34A or the auxiliary base 34B mounted on the base 22, the jaws 64 of the vise 62 being intended to be arranged on either side of this central portion 25 along the transverse direction Y.

[0078] In the example of Figures 2 to 5, the sole 22 extends:

[0079] - between a front edge 26A and a rear edge 26B along the longitudinal direction X;

[0080] - between a left edge 28A and a right edge 28B along the transverse direction Y.

[0081] Advantageously, with reference to [Fig. 5], the sole 22 delimits a plurality mounting holes 30 intended to cooperate with fixing elements 98 for mounting the base 34A or the auxiliary base 34B on the base 22, and in particular where appropriate for mounting the fixed reinforcement 92 on the base 22.

[0082] Even more advantageously, the sole 22 delimits a plurality of mounting holes 31 intended to cooperate with fastening elements (not illustrated) to mount the sole 22 on the receptacle 14.

[0083] As will be described in more detail below, with reference to figures 3 and 4, the base 22 further delimits at least one groove 76 for guiding the translation device 74.

[0084] In the example of figures 2 to 5, the base 22 further includes lifting rings 32.

[0085] The lifting rings 32 are for example arranged on the left edge 28A and right edge 28B of the base 22 and are suitable for being hooked by a lifting device for lifting the base 22, for example in the case where the base 22 should be changed.

[0086] The 34A base is suitable for receiving the equipment to be tested.

[0087] The base 34A is suitable for being removably mounted on the base 22, in particular on the upper surface 24A of the sole 22, in particular on the central portion 25 of the upper surface 24A.

[0088] Advantageously, the 34A base includes a 36A base.

[0089] Even more advantageously, the base 34A includes a stop element 44A.

[0090] Even more advantageously, with reference to Figures 4 and 5, the base 34A comprises at least one 54A mounting device for the equipment under test, in particular two 54A mounting devices as illustrated in the example in Figures 2 to 5. In particular, at least one 54A mounting device is specific to the equipment under test. For example, at least one 54A mounting device is removablely mounted on the base 36A of the 34A base, so that it can be replaced by another mounting device depending on the equipment under test.

[0091] Further advantageously, with reference to figures 2 and 5, the base 34A defines at least two vertical through-holes for fixing 56A extending along the vertical direction Z.

[0092] Even more advantageously, with reference to [Fig.4], the base 34A defines at least two horizontal fixing holes 58A extending along the transverse direction Y.

[0093] Even more advantageously, the base 34A has a length LA measured along the longitudinal direction X.

[0094] Base 36A defines a surface 38A for receiving the equipment to be tested.

[0095] Advantageously, the surface 38A further defines a central recess 43 intended to be kept away from the equipment under test. The recess 43 helps to reduce friction on the equipment under test during burn-in.

[0096] In particular, the receiving surface 38A of the base 36A extends in the horizontal plane PH.

[0097] Advantageously, the receiving surface 38A of the equipment to be tested has a geometry and / or an arrangement of fastening elements specific to the equipment to be tested.

[0098] For example, the receiving surface 38A of the equipment to be tested has an area substantially equal to the area of ​​a lower surface of the equipment to be tested, coming into contact with the receiving surface 38A when the equipment to be tested is placed on the base 36A.

[0099] In particular, the surface 38A receiving the equipment to be tested has a length LSA1, measured along the longitudinal direction X, and a width LSA2, measured along the transverse direction Y.

[0100] In particular, the receiving surface 38A is opposed to a lower surface 40A of the base 34A arranged on the upper surface 24A of the base 22 when the base 34A is mounted on the base 22.

[0101] Advantageously, the base 36A has substantially the shape of a rectangular prism. A top face of the rectangular prism defines the receiving surface 38A.

[0102] Advantageously, when the base 34A rests on the fixed reinforcement 92, the receiving surface 38A extends along the front edge 26A of the sole 22. This allows easier access to the receiving surface 38A for operators.

[0103] The stop element 44A forms a stop against which the equipment to be tested is intended to bear in the longitudinal direction X, in particular when the equipment to be tested is mounted on the base 34A, in particular on the receiving surface 38A.

[0104] The stop element 44A extends projecting from the base 36A of the plinth 34A in the vertical direction Z.

[0105] In particular, the stop element 44A extends in projection from a rear edge 37A of the base 36A of the plinth 34A.

[0106] Advantageously, the stop element 44A is substantially in the shape of a prism. One of the faces connecting the bases Bl, B2 of the prism forms a stop surface 46A against which the equipment to be tested is intended to bear along the longitudinal direction X.

[0107] For example, the abutment surface 46A extends in a vertical plane PV substantially parallel to the lateral Y and vertical Z directions.

[0108] Even more advantageously, one of the faces connecting the bases Bl, B2 of the prism has at least one inclined surface 48A extending from the face forming the stop surface 46A to the base 36A.

[0109] Even more advantageously, the stop element 44A and the base 36A were made of material.

[0110] Advantageously, at least one centering pin 50A, or in particular two centering pins 50A as illustrated in Figures 2 and 3, of the base 34A is arranged on the stop surface 46A. At least one centering pin 50A is intended to cooperate with the equipment under test to guide its positioning on the receiving surface 38A. In particular, at least one centering pin 50A is specific to the equipment under test. For example, at least one centering pin 50A is mounted removably on the stop surface 46A, so that it can be replaced by another centering pin depending on the equipment under test.

[0111] At least one fixing device 54A is intended to fix the equipment to be tested on the receiving surface 3 8A.

[0112] In particular, at least one fastening device 54A is arranged on a front edge 35A of the base 34A, in particular of the base 36A of the base 34A, so that when the base 34A is mounted on the foot 22, at least one fastening device 54A extends along the front edge 26A of the foot 22. This allows easy access to at least one fastening device 54A for an operator.

[0113] At least one vertical through-hole 56A1 among the at least two through-holes 56A of the base 34A extends through the base 36A, through the receiving surface 38A in the vertical direction Z.

[0114] The other at least one vertical through orifice 56A2 extends through the base 36A and the stop element 44A in the vertical direction Z.

[0115] Advantageously, each vertical through hole 56A of the base 34A is intended to be arranged opposite a mounting hole 30 of the base 22.

[0116] Advantageously, for each vertical through-hole 56A of the base 34A, a fastening element 98 is intended to extend through said vertical through-hole 56A of the base 34A to a corresponding mounting hole 30 of the base plate 22. Said fastening element 98 is intended to cooperate with said mounting hole 30 to secure the base 34A to the base plate 22. Said fastening element 98 is also capable of cooperating with said mounting hole 30 to secure the auxiliary base 34B to the base plate 22. In particular, the cooperation of each fastening element 98 with the corresponding mounting hole 30 and the corresponding vertical through-hole 56A makes it possible to lock the orientation and position of the base 34A or the auxiliary base 34B on the base plate 22. This ensures the repeatability and reproducibility of the burn-in.

[0117] At least one horizontal orifice 58A1 among the at least two horizontal orifices 58A of the base 34A extends from a transverse face 39A1 of the base 34A and the other at least one horizontal orifice 58A2 extends from the opposite transverse face 39A2 of the base 34A.

[0118] Thus, each of the at least one horizontal orifice 58A1, 58A2 is intended to be opposite a jaw 64 of the vise 62.

[0119] The vise 62 comprises two jaws 64 movable in translation along the transverse direction Y.

[0120] The vise 62 is intended to hold the base 34A or the auxiliary base 34B in position along the transverse direction Y between the two jaws 64.

[0121] The two jaws 64 are intended to be mounted on the base 22, in particular on either side of the base 34A or the auxiliary base 34B in the transverse direction Y.

[0122] According to the example illustrated in figures 2 to 5, each jaw 64 has substantially the shape of a rectangular prism.

[0123] For example, each jaw 64 has a length LC, measured along the longitudinal direction X, substantially equal to the length LA of the base 34A and to the length LB of the auxiliary base 34B.

[0124] Advantageously, as illustrated in figures 2 to 4, each jaw 64 includes at least one vertical through hole 66.

[0125] Advantageously, as illustrated in Figures 2 and 4, each jaw 64 includes at least one horizontal through hole 68.

[0126] Each vertical through hole 66 of the jaws 64 is intended to be arranged opposite a corresponding through guide groove 76.

[0127] Each horizontal through hole 68 of the jaws 64 is intended to be arranged opposite a horizontal hole 58A of the base 34.

[0128] Advantageously, for each horizontal through hole 68 of the jaws 64, a fastening element 69 is intended to extend through said horizontal through hole 68 of the jaw 64 to the corresponding horizontal hole 58A of the base 34A or the auxiliary base 34B. Said fastening element 69 is intended to cooperate with said horizontal hole 58 of the base 34A or the auxiliary base 34B to secure the jaw 64 corresponding to the base 34A or the auxiliary base 34B.

[0129] Even more advantageously, for each fastening element 69, a shear spacer 70 of the corresponding jaw 64 is arranged around the fastening element 69. This spacer 70 is configured to take up at least part of the shear forces applied on the corresponding fastening element 69.

[0130] The translation device 74 comprises, for each jaw 64:

[0131] - at least one through guide groove 76; and

[0132] - for each through guide groove 76, a positioning mechanism 80 of the corresponding bit 64.

[0133] In the example of figures 2 to 5, the translation device 74 includes for each jaw 64 a through guide groove 76.

[0134] Each guide groove 76 extends through the base 22 in particular along the vertical direction Z.

[0135] Each guide groove 76 further extends substantially in the transverse direction Y.

[0136] In particular, at least one guide groove 76 of one jaw 64A among the two jaws 64 is symmetrical to at least one guide groove 76 of the other jaw 64B among the two jaws 64 with respect to a median sagittal plane PSM of the receiving support 20.

[0137] Each guide groove 76 has flared edges 77.

[0138] In particular, the cross-section of each guide groove 76 taken along a plane substantially parallel to the longitudinal direction X and the vertical direction Z has substantially the shape of a V, the tip of the V being substantially arranged at the level of the upper surface 24A of the base 22.

[0139] In particular, the width of each guide groove 76, measured along the longitudinal direction X, is substantially decreasing along the vertical direction Z on at least part of the distance separating the lower surface 24B and the upper surface 24A of the sole 22, in the direction of the upper surface 24A.

[0140] Each positioning mechanism 80 is integral with the corresponding jaw 64.

[0141] Each positioning mechanism 80 is intended to cooperate with the groove of corresponding guide 76 to guide the translational movement along the transverse direction Y of said jaw 64 and / or to maintain said jaw 64 in position along the transverse direction Y.

[0142] In particular, each positioning mechanism 80 includes a screw 82 integral with the corresponding jaw 64 and a complementary screwing member 86.

[0143] The screw 82 includes a shank 84 extending in the corresponding guide groove 76.

[0144] In particular, the screw 82 is intended to extend through a corresponding vertical through hole 66 of the corresponding jaw 64 into the corresponding guide groove 76.

[0145] For example, screw 82 has a thread.

[0146] The complementary screwing member 86 extends into the corresponding guide groove 76.

[0147] The complementary screwing member 86 is intended to cooperate with the shank 84 of the corresponding screw 82 by screwing.

[0148] The complementary screwing member 86 has a cross-section taken along a plane substantially perpendicular to the transverse direction Y substantially complementary to a cross-section of the corresponding groove 76 taken along the plane substantially perpendicular to the transverse direction Y.

[0149] The complementary screwing member 86 has external surfaces 88 intended to cooperate with the flared edges 77 of the corresponding guide groove 76.

[0150] For example, the complementary screwing member 86 includes a tapping substantially complementary to the thread of the screw 82.

[0151] For example, the complementary screwing element 86 is a dowel.

[0152] Each screw 82 is configurable between:

[0153] - a screwed configuration in which the complementary screwing member 86 corresponding cooperates with the flared edges 77 of the corresponding guide groove 76, notably by friction, to hold said jaw 64 in position along the transverse direction Y; and

[0154] - an unscrewed configuration in which the complementary screwing member 86 cooperates with the flared edges 77 of the guide groove 76 to guide the translational movement along the transverse direction Y of the corresponding jaw 64.

[0155] Each screw 82 is movable between the screwed configuration and the unscrewed configuration by screwing / unscrewing the screw 82 relative to the corresponding complementary screwing member 86.

[0156] The fixed reinforcement 92 is mounted, in particular permanently, on the sole 22.

[0157] The fixed reinforcement 92 forms a stop against which the base 34A or the auxiliary base 34B is intended to bear weight along the longitudinal direction X.

[0158] Advantageously, with reference to [Fig.5], the fixed reinforcement 92 includes at least one pin 94 intended to cooperate with the base 34A or the auxiliary base 34B to guide the positioning of the base 34A or the auxiliary base 34B on the base 22.

[0159] Advantageously, the base 34A further comprises at least one accelerometer 93, for example mounted on the stop element 44A. The positioning of the accelerometer(s) 93 improves the reproducibility of the burn-in.

[0160] The auxiliary base 34B is adapted to receive an auxiliary test equipment different from the equipment to be tested.

[0161] In particular, the auxiliary equipment to be tested includes a lower surface intended to come into contact with a receiving surface 38B of the auxiliary base 34B, having a different area from the lower surface of the equipment to be tested.

[0162] With reference to [Fig.6], the auxiliary base 34B is suitable for being mounted removably on the base 22, in particular on the upper surface 24A of the base 22, in place of the base 34A.

[0163] The auxiliary base 34B includes a base 36B defining the receiving surface 38B of the auxiliary equipment to be tested.

[0164] Advantageously, the auxiliary base 34B includes a stop element 44B.

[0165] Even more advantageously, the auxiliary base 34B has a length LB measured along the longitudinal direction X substantially equal to the length LA of the base 34A.

[0166] The receiving surface 38B of the auxiliary base 34B extends in a horizontal plane substantially parallel to the longitudinal X and transverse Y directions.

[0167] The receiving surface 38B of the auxiliary equipment to be tested has a geometry and / or an arrangement of fastening elements specific to the auxiliary equipment to be tested.

[0168] For example, the receiving surface 38B of the auxiliary equipment to be tested has an area substantially equal to the area of ​​the lower surface of the auxiliary equipment to be tested.

[0169] In particular, the receiving surface 38B of the auxiliary equipment under test has a length LSB1, measured along the longitudinal direction X, and a width LSB2, measured along the transverse direction Y. Advantageously, the length LSB1 of the receiving surface 38B of the auxiliary base 34B is different from the length LSA1 of the receiving surface 38A of the base 34A and / or the width LSB2 of the surface The receiving surface 38B of the auxiliary base 34B is different from the LSB1 width of the receiving surface 38A of the base 34A.

[0170] In a specific example, the auxiliary base 34B is substantially identical to the base 34A, except for the length and / or width of the receiving surface 38B, the centering pin(s) 50A, and the fastening device(s) 54A. "The auxiliary base 34B is substantially identical to the base 34A" means, in particular, that the auxiliary base 34B also includes a base, a stop element, at least one fastening device, vertical through-holes for fastening, and horizontal holes for fastening similar to those of the base 34A, but that, for example, the dimensions of the receiving surface and / or the stop element are different from those of the base 34A. In one variant, the auxiliary base 34B has a different shape from the base 34A, in particular to be adapted to the auxiliary equipment under test. In all cases, the auxiliary base 34B remains suitable for mounting on the base 22.

[0171] Advantageously, the mass of the base 34A and the auxiliary base 34B is less than or equal to 5 kg and the mass of the base 22 is between 5 kg and 25 kg.

[0172] The following describes a method 100 of using the debugging system 10.

[0173] Advantageously, the method 100 includes a step 110 of mounting the sole 22 on the actuation device 12.

[0174] The method 100 includes a step 120 of mounting the base 34A onto the sole 22.

[0175] The method 100 further includes a step 130 of mounting the equipment to test on the 34A socket.

[0176] The method 100 further includes a step 140 of generating mechanical stresses on the equipment to be tested by the actuation device 12.

[0177] Advantageously, the method 100 further includes a step 150 of dismantling the equipment to be tested.

[0178] Advantageously, the method 100 further comprises a step 160 of mounting the auxiliary base 34B onto the base 22 in place of the base 34A. Thus, in step 160, the base 34A is removed from the base 22 and the auxiliary base 34B is mounted onto the base 22.

[0179] Even more advantageously, the method 100 further includes a step 170 of mounting the auxiliary equipment to be tested on the auxiliary base 34B.

[0180] Even more advantageously, the method 100 further includes a step 180 of generating mechanical stresses on the auxiliary equipment to be tested by the actuation device 12.

[0181] In particular, during step 160 of process 100, process 100 does not include a step for dismantling the sole 22. Thus, the process allows the following to be carried out: tests on the equipment to be tested and on the auxiliary equipment to be tested without requiring replacement of the base 22. Only the base 34A is replaced by the auxiliary base 34B, which greatly facilitates handling operations.

[0182] Advantageously, in step 160, the fastening elements 69 are disengaged from the horizontal through holes 68 of the jaws 64 and from the horizontal holes 58A of the base 34A, and the screws 82 are detached from the additional screwing elements 86 to allow the jaws 64 to be moved apart from the base 34A, and the fastening elements 98 are detached from the mounting holes 30 and from the vertical through holes 56A to allow the base 34A to be removed from the sole 22. In particular, when the auxiliary base 34B has a width LSB2 greater than or equal to the width LSA2 of the base 34A, the jaws 64 of the vise 62 are sufficiently separated from each other in the transverse direction Y to allow the auxiliary base 34B to be inserted between the jaws. 64 and the mounting of the auxiliary base 34B on the base 22, in particular on the central portion 25 of the upper surface 24A of the base 22.Next, when the auxiliary base 34B is mounted on the base 22, the jaws 64 of the vise 62 are again brought closer together in the transverse direction Y so that the vise 62 holds the auxiliary base 34B in position in the transverse direction Y between the two jaws 64.

[0183] Thanks to the invention, it is possible to replace only the base when different types of equipment need to be tested, without having to replace the soleplate. This greatly facilitates handling operations since the heavy load of the soleplate does not need to be lifted.

[0184] In addition, since the base is common for the plinth and the auxiliary plinth, the bulk generated by the system is reduced because it is not necessary to use a suitable base for the auxiliary equipment to be tested.
